A Study on the Development of Canal in Nakdong-River
Full text linkAll the nations that utilized well the water and waterways have been prospered from the ancient civilization to the present. Even now, the advanced nations such as the United States of America and several European countries have been contributing much to the national economy by utilizing waterways well. However, our country has utilized rivers only transportation means of materials but at present, as the roads have been constructed depending almost upon the purpose of transportation of materials instead, it is determined that construction of road is no longer able to be made and reached to the limit due to increase of construction cost of roads and encroachment of national land. At the same time a harmful influence has been given upon the envelopment caused by hazardous materials that are discharged from vehicles. The advanced European countries have been not only transporting cargoes using small size ships through waterway from the land to harbor but also earning a lot of tourist income through waterway sightseeing.
Nakdong river is the longest in our country connecting to the inland area. In order to eliminate excessive construction cost and to promote smooth transportation of materials by utilizing the waterways well as transportation means in our country, some researchs on practical use of Nakdong river need to be conducted. Especially, in consideration of the situation such as the depth and width of the river, and based on the situation, the river development has to be carried out.
Therefore, this study aims to investigate the possibility on the canal development of Nakdong river in view of engineering point.
The actual utilization of waterway of our country, development of transportation means using waterways should be made for the future.목차

A Study on the Dispute of Islands in the Northeastern Asia:With Emphasis on the Territorial Dispute about Tokdo
Full text linkUnited Nations Convention on the Law of the Sea had been concluded in 1982 through a long session, and by many times of argument, and entered into force in November, 1994. United Nations Convention on the Law of the Sea that 157 States put an agreement under their signature, 138 nations ratified up to now February, 2002 was arranged as The Magna Carta of the sea.
United Nations Convention on the Law of the Sea has an object to settle dispute between subjects of International law, or to settle dispute that has already occurred between subjects of International law in an amicable way. In the northeastern Asia, United Nations Convention on the Law of the Sea did not achieved it's object, but produced "a quite contrary result". Because United Nations Convention on the Law of the Sea regulates the exclusive right of the coastal State positively, and the coastal States are anxious to expand the bounds of the sea that they can govern like land.
This phenomenon is detected obviously at the dispute of islands. In the northeastern Asia, Korea, Japan, China(Taiwan), and Russia are pitted against each other for its interest on the other side of the sea. They recognize the importance of the sea, so it leaves some room to dispute.
In the northeastern Asia, there are 3 disputes of islands. Russia and Japan are pitted against each other about the islands of the southern Kuril Islands, and the confrontation of small island adjacent Taiwan is going on.
Firstly, dispute about "Northern Territories(Japan designated)" between Russia and Japan. Secondly, dispute about "Senkaku Islands(Japan designated)" between China, or Taiwan, and Japan.
The third, the last, one is the dispute about "Tokdo" that the antagonism is going on.
When I study about dispute about "Tokdo", first of all, I arrange two aspects of dispute about "Tokdo".
The Northen Territories is occupied by Russia, but there is stronger will of Japan about the Northern Territories than will of Japan about other disputing region, so there is substantial negotiation using economic support as intermediation at the northern territory. In 1991, since The Soviet Union broke down, both Russia and Japan cleared hostile relation, and built companion relation under the end of the Cold War, furthermore they made diplomatic effort to settle dispute about territory.
Specially, with collapse of The Soviet Union, New force of Reformation in Russia that got faced with total crisis established a principle that they return four islands of Kuril Islands by stages on condition of economic support in a big way. Also, Japan that concluded that they could recover the northern territory, because the Yeltsin adminstration needed economic support of Japan after the end of the Cold War, so Japan concentrated on negotiation about the northern territory on condition of economic support. As a result, both Russia and Japan reached conclusion with adopting the joint declaration
There are some importances that China can't concede Senkaku Islands. Firstly, in the southern sea of China, any concession can't be expected, because the southern sea of China is related other dispute of island, secondly, existence of petroleum is clarified at the coast, therefore China is expected that it shows the effectiveness of armaments to consolidate the effectiveness against this waters, or that it tries substantial exploration to make foundation of possession.
Against this, Japan is evading positively the phenomena that lead the result that can magnify or deepen character of dispute to maintain substantial control. Senkaku Islands are certainly belongs to Japan, therefore what is useless to debate about Senkaku Islands are Japan's standpoint.
Japan's will looks passive against "Tokdo" as compared to Japan's will about the northern territory and standpoint of Senkaku Islands, but it is very positive as compared to position of Korea. As compared to the government of Korea that insists "no dispute" about "Takesima(Japan designated)"-like Japan that insists "no dispute" about dispute about Senkaku Islands-, the government of Japan stresses that there is a dispute by formal announcement of the government of Japan with presenting wrongfulness about the occupation of "Tokdo" of Korea.
Japan is the nation that adopts expansive policy of the sea, with establishing exclusive economic zone, continental shelf, or straight baseline for its interest from the island that doesn't satisfy essential condition for island. With considering these factors, against dispute about island, Japan is expected that it doesn't concentrate on triumph on one place, but it aims at overall triumph.
There is no guarantee not to apply the method of Japan that lead advantageous situation of Japan by progress of negotiation through economic intermediation, or by manipulation of public opinion of circumference for "Tokdo", therefore Korea has to prepare certain foundation about assertion of dominium of "Tokdo", with dismissing disregarding, and avoiding position about phenomenon.목차

Effects of the Load Changes of Diesel Engine Driven Generator on the Torsional Vibration
Full text linkA number of researches on the torsional vibration of vessel's propulsion shafting system have been conducted. But the research on shafting system of driven generator in a diesel engine has hardly been reported, because the system has been considered as less important. However, if the engine power is increased, the shaft can be easily broken down by the incorrect design without considering its excessive torsional torque.
In this study, the effect of the torsional vibration amplitude by increasing load of the driven generator was conducted on actual operation of diesel engine, and the result was that the increase of torsional vibration amplitude was very infinitesimal in proportion to the load increase. The reason is that the more increasing the load is the more increasing the exciting force, which results the torsional vibration increases. Moreover, the dumped force is increased due to the damper winding of the diesel engine driven generator.
The excessive torsional vibration in the shaft occures when generator's parallel operaton begins or when auxiliary machines suddenly start or stop while normal load operation, Through the experiment of the effects about the load variation on the vibration of a generator's shaft, It was found that the torsional vibration amplitude increased about 56% during the "ABC-on", and 44% during the "ABC cutoff", compared to the condition before "ABC-on". In addition to, when the load suddenly change, the torsional vibration amplitude increased about 138% compared to that of steady-state load.
It seams important that these results might be considerd for generator shaft designs and Register's approvals.Abstract

An Experimental Study on Exhaust Gas Emission Characteristics according to the Piston Crown Cavity of Diesel Engine
Full text linkRecently the environment of the world has been exposed to the severe air pollution emitted from the rapid developing industries. And the necessity of controlling the emission from the diesel engines such as NOx, PM, SOx, COx also has been raised up gradually. Among them the NOx emission from the oceangoing vessels has been layed under regulation from international convention of MARPOL Annex Ⅵ of IMO, dated from 1st January, 2000.
Various measures have been tried to reduce the NOx emission from diesel engine but with partial success, because the mechanisms of NOx formation and PM formation appear to have trade-off relation between each other. Therefore it has been known to be difficult to reduce NOx emission and PM emission simultaneously.
Two stage combustion method ie. a combustion process which has rich combustion stage and lean combustion stage one by one, has been developed successfully to reduce NOx formation in continuous combustion chambers such as in the boilers. But until yet it is not successful to apply the same method in intermittent combustion chamber like in the diesel engine cylinder, as it was, only several research works were carried out.
In this study the various modification of configurations of piston crown and spray impingement was attempted to attain a geometry that realize the two stage combustion in the diesel engine cylinder and to acquire a simultaneous reduction of NOx and PM.
It was found that the NOx emission decreased significantly at various condition of operation both with the two stage combustion type engines & impinge swirl type engines of this series of configuration, but other values such as smoke, CO and specific fuel consumption deteriorated as usual. And it was suggested that the weakening of swirl intensity due to the existence of radial division of rich-lean combustion region and reduction of penetrating momentum due to the spray impingement act as a reason of ineffectiveness of this series of combustion chamber geometry.목차

An Empirical Study on Consumer's Perception and Purchase Attitude in Internet Business based on Life Style
Full text linkThe internet business sharply becomes activated along with the recent rapid increasing of Internet Using. The biggest reason which the business through the internet makes activated is which the customer is easily acquired without the time and space restriction, and every charge and expense under the commercial business transaction can be largely reduced, and also it has appeared as the new market which overcomes the time and space restriction owned by the traditional market and unites the whole world beyond the concept of border.
Therefore, the purpose of this study is to examine the characteristics as like the life style, attitude and character of consumers based on the internet business formed by the environmental and psychological factors upon the Demographical characteristics, to understand the recognition standard toward the internet purchasing of University Students in Busan, Korea, to analyse the peculiar life style of consumers who purchase the products through the internet upon its type, and then to clarify which the group upon the type of each life style has any effect upon each purchasing attitude, and also to subdivide the market based on it, and thus to establish the marketing strategy upon the analysis results.
In this study, I would like to analyze the recognition and purchasing attitude of consumers toward the internet business upon the type of life style of University Students in Busan, Korea empirically.
Also, I kept pace with the theoretical study and the empirical study in order to analyse the recognition and purchasing attitude of consumer toward the internet business upon the life style.
At first, I executed the theoretical and document consideration with regard to the concept and the characteristics of life style. Through the document study, I arranged the life style , concept and purchasing attitude of consumer's behavior, the purchasing course of consumer through the internet business, the concept of internet business, the development and problems of internet business and the cyber marketing constituents of internet business and empirically analysed the relationship per the constituents upon the type of life style of University Students in Busan, Korea.
In the empirical study, I collected the data by use of the questionnaire method based on AIO Analysis, centering around the university students located at Busan, Korea.
The frequency analysis was made by use of SPSS for win10.0 in order to check the characteristics of sample and then the factor analysis to examine the propriety of each variable.
Then, the cluster analysis was carried out not only to classify the type of life style by use of factorial discretion extracted from the factor analysis but also to find out any difference in the attitude of consumers toward the internet purchasing upon the characteristics of each group by the type of life style. Also the ANOVA(Analysis of variance) was carried out in order to examine the differences in the purchasing attitude upon Demographics.
The Results of this analysis are as shown in the followings.
Firstly, as the results of understanding the recognition standard and the actual using conditions of university students in Busan, Korea toward the purchasing
attitude through the internet, 310 persons which is 70.2% of the replier 440 persons answered which they have the experience to purchase the goods through the internet and thus it is investigated which many students have actually purchased the goods through the internet.
Secondly, I intended to classify the type of life style of university students in Busan, Korea through AIO variables used in the study of life style, centering around the university students in Busan, Korea.
As its results, the university students were subdivided into 4 life style groups, and the first group was named as the Rational Self-Pursuit Type, the second group as the introspective self-centering type, the third group as the conservative activities type and the fourth group as the positive dignity-keeping type.
Thirdly, as the results of clarifying which there is any difference in the purchasing attitude through the internet upon the group of each life style type, the purchasing attitude statistically showed the significant difference in every item upon the life style.
Fourthly, as the result of executing the ANOVA in order to clarify which the purchasing attitude toward the internet business has any difference in the Demographic variables, it showed the significant difference about the searching course on the internet, but it appeared which there is no significant difference in other items.
Through the above-mentioned results of study, the university students have the characteristic life style and it can be known which they show the different purchasing attitude upon the life style.
This study has supplied the effective standard to clarify the consumer of target market on subdividing the purchasing market through the internet, and systematically classified and suggested the preference upon the concrete characteristics of target consumer which becomes the target market, and thus when the market mix for reaching the target group very effectively is decided, this study will offer the valuable information.목차

(A) Study on Construction of Real Time Ship-Handling Simulator Using the Distributed Processing Network Method
Full text linkAs sea traffic has been complicated and ships have been enlarged recently, we require a safety of ship in the coastal and areas. Although the maneuvering performance of ship herself almost clearly become, the important control quality of human being is not exactly grasped. The real time ship-handling simulator can be used as the most useful way when we understand the safety of ship maneuvering performance in the harbor area. The most important things of real time ship handling simulator are mathematical model and 3 dimensional image. We can manage the 3 dimensional image by using the 3 dimensional graphic technique. The distributed processing method is thought as one of the most effective ways to network communication system. We developed the real time ship handling simulator using the distributed processing network method.Abstract = 1

Korean Eojeol Classification Using Instance-based Learning
Full text linkGenerally, Internet users have exploited search engines to find the information that they need. Such search engines require fast processing and particularly morphological analysis in Korean. The notorious problem in Korean morphological analysis is over-generation, which is caused by the lack of morphotactics. This paper describes the eojeol classification in order to lighten the burden of the over-generation. In other word, we want to reduce the search space for morphological analysis using eojeol categories. In this paper, we propose a method for eojeol classification using an instance-based learning technique.
To evaluate our proposed system, we use two test corpora (KAIST and ETRI) that are part-of-speech tagged in Korean. In addition, we use the cross validation method for training and evaluation since the test corpora are not enough. The average accuracies of the test corpora are 97% and 96.6% under 22 features, respectively, but the average accuracy is reduced into 95.5% even though the two corpora are combined. We believe that the tragedy results from the inconsistent tagging method in spite of the larger amount of training data. To select optimal features for our system, we employ backward sequential selection. As a result, we choose 16 features as the optimal features and the performance of our system is improved by about 0.2%. Furthermore the reduction rate is 35% on average when our system is applied to Korean morphological analysis.목차
