A Study on the Enhancement Strategy for Operational Efficiency in Busan Container Terminal:Primarily on ON-Dock System
Full text linkIn 2000, the port of Busan gets to be jumped as the port which handles the third materials mobilization quantity of container in the world.
In spite of this outward progress, the current of container has been passed through ODCY as like the former days, and thus the expenses of materials distribution payable by the consignee has not been reduced and the intra-urban traffic congestion caused by the transportation vehicles of container has not been improved.
So, the container terminal which has operated the existing marshalling yard gets to introduce On-Dock System which offers the overall service of unloading, keeping and transporting within the container terminal for the purpose of reducing the traffic congestion, making the high added value on the service given by the container terminal , reducing the expenses of materials distribution and improving the service quality toward the customer.
It can be said to be essential which the time required to when the consignee is shipped to the vessel from the door of consignee, and to when it is delivered to the cargo owner after the discharging of cargo makes minimized and thus the expenses makes reduced and also the quality of service is improved.
Therefore, it is expected to be contributed to the reduction of materials distribution expenses between the parties concerned as well as it enhances the competition of container terminal and the consignee and shipping companies can be guaranteed the high-quality-service.
So, the purpose of this study is as shown in the followings.
First, the operational system of existing container terminal will be analysed , centering around the port of Busan.
Secondly, the current conditions of container terminal On-Dock in the port of Busan will be analysed and then will be compared with ODCY system.
Thirdly, the problems of On-Dock System Operation of container terminal in the port of Busan will be analysed in the practical tendency.
Fourthly, the effective improvement way for the operation of container On-Dock System will be suggested.
As the method and scope of this study, I jointly performed the analysis which uses the secondary data and the interview with the person in charge of field together with the literature investigation in order to consider the current conditions of container terminal in Korea and the efficient improving way of On-Dock System.
At first, I arranged the current conditions and function of container terminal in the port of Busan through the existing literature study on the function of port and container terminal and On-Dock system, and jointly executed the meeting with the person in charge of the shipping company which uses On-Dock and the interview with person in charge of field which gives On-Dock Service, and looked for the efficient improving way of On-Dock System based on the problems shown these interviews.
As result of analysing this study, it is the directions of container terminal to be progressed which it offers the optimal On-Dock Service as like the necessity of Network Unification through the rationalization of materials distribution from now on.
The container terminal offers the high-quality service together with the expenses reduction and thus will be able to maximize the satisfaction of shipping company, consignee and transportation company which are the customer. Moreover, the container terminal will have to seek positively the relative marketing strategy which lays stress on the continuous relationship with the major customers and then to be accustomed to the ambient environment of rapidly-changing container terminal.
The container terminal operational way must be sought in the strategic scope together with the stabilized acquisition of materials in order to be existent in the extreme competition with each container terminal.
In order to accomplish the management target as like the effective operation of container terminal, the effective On-Dock System Making will be able to be said as the essential object.목차

Force Tracking Control for the Hydraulic Servosystem using a Proportional Pressure Control Valve
Full text linkThe fluid power system is applied to various fields of modern industries because it is able both to generate great force or torque and to control precisely the movement of hydraulic actuators. Amongst those to which the fluid power is applied, active suspension system and four wheel steering system on a passenger car have the force control hydraulic servosystem.
The electro-hydraulic servo valve and the proportional pressure control valve can be used as control valve, an essential component of the force control hydraulic servosystem. The electro-hydraulic servo valve requires feedback of control output in the hydraulic servosystem. But the proportional pressure control valve does not require feedback of control output in the force control servosystem.
In this paper, the linear model of the hydraulic servosystem for force tracking control which consists of a proportional pressure control valve and a double acting cylinder is derived. The performance of the hydraulic servosystem is analysed through computer simulations. And the limitations on designing the controller in feedback control system are studied. In addition, performance of position tracking control system as well as the limitations on feedback control is examined.
In the force tracking hydraulic servosystem, the velocity of piston acts as feedback term from the position output of the cylinder to pressure differential across the piston. Therefore, the poles of the plant manifest themselves as the zeros of the open-loop transfer function. Moreover, these zeros can't be changed via feedback and simple algorithms are severely bandwidth limited. In the position tracking control system, by the stable pole-zero cancellation the poles of the plant do not appear as the zeros of the open-loop transfer function.
The result from the study shows that a simple algorithm for force tracking purposes beyond the bandwidth limitation is not suitable and the need of more advanced algorithms are confirmed. On the other hand, It is confirmed that the position control system is properly controlled by means of simple algorithms.Abstract = 1

A Study on Navigable Areas for Improvement of the Korean Ship Safety Act
Full text linkNavigable Areas System for Vessels was firstly introduced by Vessel safety Ordinance of Japanese Government-General of Korea in 1935 and the same statute had been applied after independence. Above all, because Vessel safety Ordinance that enacted in 1961 was carried on Japanese Statute, the Navigable Areas System that Japan set the area includes Korea in 1966 is using by this time.
There is 4-district system for navigation area in the Korea Ship Safety Actphysical factors of hull, systemic factor for safe navigation and human resources factor, which is main subject for safe navigation. However, every factor that determines the broad seaworthiness abilities is remarkably developed than 1966 and we cannot deny it has big differences with actuality.
Based on the facts, this thesis tried to examine the historical background and progresses that established navigation zone and compare it with present navigation zone system by studying the standard of establishment and also tried to drew the differences by comparing the physical & human matters in those days that enacted the Korea Ship Safety Act and in present. And this thesis researched the systems that was established and forced that did not existed in the past for safe navigation and explained with systemic matters. Its intention is to be the foundation of reliable information when it needs to be amended afterwards.Harbor district , inshore district , coastal district and ocean. The legislative object of the Korea Ship Safety Act is to secure the physical steadiness, that is, seaworthiness ability for vessel, which is the mean of marine transportation. The Safety for Vessel that regulated by the Korea Ship Safety Act is so-called physical seaworthiness and the restricted objects are hull, engine and equipment. Therefore, Human safety that required by Maritime Law or Maritime Transportation Regulation does not include human seaworthiness.
So, Physical seaworthiness for vessel regulated by the Kora Ship Safety Act only means hull, engine and equipment and set the basic required standard for facilities in vessel during the voyage.
The standard is the minimum standard that maintains the seaworthiness ability during the voyage in the Ocean. And the Korea Ship Safety Act is enforcing the administrative control that enlarge the seaworthiness ability with the methods to control the navigation area of relevant vessel by taking above general seaworthiness as the standard and then add the factors such as length & speed of vessel. The meaning of vessels seaworthiness, however, is physical seaworthiness for vessel and also it covers human seaworthiness including qualification and capability of sailor. Especially, the meaning of vessels seaworthiness in Marine Transportation is broad including above both two factors. The Korea Ship Safety Act is regulating only physical seaworthiness of vessel and the human seaworthiness is regulated by Regulation for shipping employees and the Korea Seamen Act.
As a result, seaworthiness of vessel that is decisive factor to set the navigation zone could be established with broad concept목차

Maritime Lien and It's Execution
No full textMaritime lien means a statutory security right with a priority to any other right to vessel and its adjuncts which admits a person having a specific maritime claim to be paid before any other creditors.
Maritime lien with a priority not having a public notice may damage to the other creditors. And the ship's arrest for the enforcement of maritime lien may stop the ship's operation. So adjustment of the interest between the person concerned is requested.
Maritime lien's recognition was found in the theory of procedural, personification, Conflict, and now in the special circumstances of the maritime corp., limitation of the ship owner's liability, public policy, causam pignoris facere etc.
Claims with maritime liens are discussed for the adjustment of interest between a liener and any other creditor. The Commercial Law at art 861(1) provides the claims for which a maritime lien is risenIndemnities for collisions and for damage caused to voyage facilities, harbour facilities and navigable ways by other accident of navigation, indemnities for personal injury to passenger or crew.
A suggestion to the legislation of the claims is in the adjustment of the claims' scope and rank, of the scope of debtor, and the differentiation of maritime liens.
The conflict if interest between owner and liener is shown in the enforcement of maritime lien. For the owner, (1)the order of delivery of a ship's nationality certificate before the application of the sale, (2)the order of anchorage, (3)the order of receipt of a ship's nationality certificate, and (4)the measure of watching and preserving are prescribed.
A suggestion to the legislation of the enforcement of maritime lien is in the deletion of the application of mortgage(art 681(2) second sentence), the deletion of the prohibition of arrest, the revision of the admission of navigation, the prescription for the withdrawal of the arrest by security letter and the certificate for no-security right and ship registration.Remuneration for salvage and the contribution of the vessel in general averageCalms arising out of the contract of engagement of the crew and other persons hired on boardLaw costs due to the State incurred in the common interest of the creditors, expenses incurred in the sale of the vessel and its adjuncts, public taxes to the vessel for the navigation, pilotage and towage dues, the cost of watching and preservation from the time of the entry of the vessel into the last port第 1 章 序論 = 1

An Experimental Study on the Evaporation Heat Transfer of R-22 in Small Tubes
Full text linkThe evaporating heat transfer of R-22 in small tubes has been experimentally studied. The tubes in present work are single square tube and single round tube. The hydraulic diameter of the tubes is 1.67㎜. The experimental apparatus consists of a refrigerant pump, a condenser and a receiver, the small-tube test section, a subcooler of liquid refrigerant, a preheater for control of refrigerant quality at the inlet of test section. The heat flux is generated by heating wire wound on the outer wall of the test section. A set of five thermocouples are embedded at the wall of the test section to measure the wall temperature at five locations. The refrigerant flow rate is measured using a high-pressure rotameter. The pressure drop across the test section is measured using a differential pressure transducer.
For refrigerant mass flux of 384 ㎏/㎡s and 570 ㎏/㎡s, the inlet qualities are varied from 0.0 to 0.8 and the wall heat fluxes are varied from 4 ㎾/㎡ to 10 ㎾/㎡. The measured evaporating heat transfer coefficients in the small tubes are 620 ∼ 4760 W/㎡K, which are lower than those observed in the typical large-diameter circular tubes. The evaporating heat transfer coefficient in the square tube shows lower heat transfer coefficient than the round tube. The pressure drop increases with increasing quality.Abstract

A Study on the Sensorless Speed Control of Induction Motor by Neural Network.
Full text linkRecently, with the development of vector control technology, induction motors has been used more in the industrial variable speed drive system.
Generally, induction motor controller requires rotor speed sensors for commutation and current control, but they increase cost and size of the motor.
So in these days, various researches including speed sensorless vector control are reported and some have been put to practical use.
Many sensorless control algorithms use mathematical model based upon analysis techniques which have been used for the steady and transient states of induction motor.
However, their control performances are greatly influenced by the parameters and load deviations. Futhermore, many difficulties occurred in starting and low-speed range.
In this paper a new speed estimation method using neural networks is proposed.
The neural network structure was again found by trial and error and it was found that the 8-16-1 neural network has given correct results for the instantaneous rotor speed.
The eight inputs to the neural network are monitored values of the stator voltages and stator currents. The neural network contains a singles hidden layer with 16 nodes, and the activation functions used in the hidden layer are tansigmoid. The output layer contains a single node, which outputs the rotor speed.
A feedback signal is necessary for only training. Supervised learning methods, through which the neural network is trained to learn the input/output pattern presented, are typically used.
The back-propagation technique is used to adjust the neural network weights during training. The rotor speed is calculated by weights and eight inputs to the neural network.
Also, the proposed methods have advantages such as the independency on machine parameter, the insensitivity to the load condition, and the stability in the low speed operation.
The results of simulation and experiment indicate good response characteristics even in the low speed range and in the parameter variation.목차

The Study on Liang Qi-chao and Shin Chae-ho's Perception for The Theory of Social Evolution
Full text linkThis paper has the purpose to study Liang Chi-chao and Shin Chae-ho's perception for the theory of social evolution. They are the representative intellectual of Korea and China from late in 19th century to early in 20th century when traditional value order is changed. From late in 19th century to early in 20th century, East Asian three countries became to face unparalleled crisis due to internal contradiction of traditional order and external impact of Western modern order. Specially, invasion of Western imperialism in earnest had intellectuals who previously absorbed in traditional thought to search the necessity to percept new reality and countermeasure for it.
Western authority revealed in the process of expansion was major cause that had revolution-oriented intellectuals to actively introduce Western thought. Utilitarianism, liberalism, the theory of social contract, democracy, the theory of social evolution and other various Western thought were introduced but the theory of social evolution was most rapidly introduced among them. The theory of social evolution was suitable for ideology to support the right of the strong in imperialism country but did a different role for East Asian country. The theory of social evolution became the theory to explain the reason that East Asian country became the weak in the struggle for existence, the method to be the strong and the necessity of modernization and civilization and provide the reasonableness for it. So the theory of social evolution in East Asian country is transformed to not the theory to justify the interest of the strong but the theory to help the weak to become the strong by itself.
But the context of Western thought absorbed in East Asian countries is different according to the corresponding method of intellectuals, the subject of absorption in each country. Specially, Japan was under different international environment to Korea and China from the view of international politic order of Confucianism area and showed lukewarm aptitude for rapid escape from international politic order of Confucianism area and rapid entry to international order of Western area through most sensitively reacting to Western menace although it was slow and narrow when it is compared to Korea and China. The resistance against new order on the basis of old order was so powerful so absorption of Western civilization was delayed.
Due to above reason, the type and context of absorbing Western thought of Korea was more similar to one of China and that Western thought introduced to Korea was not directly introduced from West but introduced through filtration of China so it has the type of indirect absorption. Specially, among many thoughts introduced to Korea, the theory of social evolution was largely influenced by one of China, specially, the theory of social evolution Liang Chi-chao largely influenced to one of Korea.
The theory of social evolution was introduced when traditional thought and Western thought was variously mixed and Liang Chi-chao and Shin Chae-ho were powerful in China and Korea respectively in the process that Western thought affects to intellectual's establishment of national thought. This paper starts studying with the assumption that two peoples' character of the theory of social evolution was similar because the transmission course that the theory of social evolution was introduced to Shin Chae-ho via Liang Chi-chao was confirmed. The reason to select those two peoples as targets was due to judgment that two people could explain the contemporary social state well because those two peoples' thought was organized early in 20th century when the conflict between traditionalism and modernization was appeared and various ideologies was absorbed.
With those assumptions, this paper will unfold study on the basis of following articles.
First, what is the background of the theory of social evolution introduced to China and Korea and how it was developed?
Second, how Liang Chi-chao and Shin Chae-ho who affected to development of the theory of social evolution of China and Korea recognized the theory of social evolution.
Third, what function has the theory of social evolution in the period of patriotic enlightenment and how it influenced to organization of the theory of nation.
Fourth, how Liang Chi-chao's Sin-min theory affected to Shin Chae-ho's Sinkookmin theory.
This paper was organized like follows.
Chapter II, Surveyed the context of the theory of social evolution of Spencer and Huxley as the assumption to absorb the theory of social evolution.
Chapter III, On the basis of understanding absorption and unfolding process of the theory of social evolution of China and Korea, in Paragraph 1, surveyed international politic environment of East Asia and the background to absorb the theory of social evolution and in Paragraph 2, surveyed the type to absorb the theory of social evolution and unfolding process of it.
Chapter IV, surveyed Liang Chi-chao's perception for the theory of social evolution. In Paragraph 1, surveyed Liang Chi-chao's organization of thought and type to absorb the theory of social evolution and in Paragraph 2, surveyed Liang Chi-chao's Sin-min theory.
Chapter V, surveyed Shin Chae-ho's Sinkookmin theory and the effect of Liang Chi-chao's Sin-min theory to it

A Position Tuning Control of Multiple Cylinders Using Variable Design-Parameter Fuzzy PID Controller
Full text linkIn general a hydraulic system which uses a single rod hydraulic as an actuator is modeled as a nonlinear system. Especially it is well known that the system reveals uncertain parameter characteristics such as the density variation of hydraulic oil and is subjected to load variations and severe disturbances during operation. In order to cope with these undesirable internal and external problems, a nonlinear and time-varying control theory is needed and must be developed.
This paper is devoted to three main objectives eventually to accomplish a synchronizing position control of multiple hydraulic cylinders.
At first, a fuzzy PID control algorithm is thoroughly discussed which has nonlinear time-varying control parameters and is named a variable design-parameter fuzzy PID control. It is developed to control the systems whose mathematical dynamics are unknown and whose behaviors reveal nonlinear system characteristics. By way of computer simulations for several example systems, the effectiveness of the suggested algorithm is proved and the online time variation characteristics of the PID control parameters such as K_p,K_d and K_i are investigated.
At second, the discussed variable design-parameter fuzzy PID algorithm is applied to the position control of a single rod hydraulic cylinder system as a real control world of typical nonlinear systems. Computer simulation results reveal that the composed system is useful and effective in view of control performance and real time control possibility.
At last, a comprising method of position-synchronizing control of multiple hydraulic cylinders is suggested. The method is to comprise the control system using only electronic devices including synchronizing control algorithm. In order to prove the usefulness of the suggested method, computer simulations are executed for two cases. One is the case two cylinders have the same specifications except for different operating conditions. The other is the case two cylinders have different specifications as well as different operating conditions.
In the conclusion, according to the simulation results, the discussed variable design-parameter fuzzy PID control algorithm turned out adequate to control nonlinear systems and revealed very accurate PID control actions regardless of operating input ranges. The suggested position-synchronizing control method was proved so effective that it could be applied to the synchronizing control of multiple hydraulic cylinders with small position differences.목차

Vehicle Control and Performance Analysis of 4WS Passenger Cars using Robust Control Techniques
Full text linkIn this dissertation, a lateral control design is presented for automatic steering of active four-wheel steering (4WS) vehicles for highway driving. The linearized two degree-of freedom (2 DOF) equations for the lateral dynamics are derived using the Newton's equations. A robust controller using -analysis and synthesis is designed for a linear model of a passenger cars moving a given path. The performance of the robust controller is then evaluated using simulation studies.
It is shown that the presented control method possesses the inherent advantages that are robust to complex uncertainty for typical driving maneuvers. Finally, the active 4WS vehicle achieves good performance for a wide range of uncertainty in the highway operating conditions
