No full textLõputöö kirjutamise vajadus tulenes tarneahela juhtimise olulisuse kasvust maailmas. Tarneahelate ja nende osade efektiivne juhtimine ja täiustamine ning varude juhtimise kaardistamine annab sisendit ettevõttes eelkõige kulusäästule. Ettevõte, millel töö põhineb - FLIR Systems Estonia OÜ on FLIR Systems Inc.’i globaalse tarneahela üks oluline lüli, olles teatud toodete ainutootja üle terve maailma. Töös käsitletud kitsas tarneahel asub FLIR Systems Estonia OÜ ning EMEA regiooni kesklao vahel. Töös kirjeldati seda tarneahelat ning kaardistati varude juhtimise meetodit selles. Töö eesmärgini jõudmiseks analüüsis autor kitsa tarneahela tooteportfelli ja selle varude tasemete tulemusnäitajate ajalugu ning kesklaost tehtud müügi statistikat. Vahend, mis loodi eesmärgi täitmiseks on varude juhtimise mudel, mida rakendades muutub kitsa tarneahela varude juhtimine täpsemaks ning S&OP plaaniga koordineeritumaks. Lisaks tõi autor välja ettepanekud nii kitsa kui FLIRi globaalse tarneahela täiustamiseks. Tulemuseni viinud analüüsi toetas teooria osa, milles autor käsitles tarneahela ja varude juhtimist ja strateegiad, prognoosimist ja nõudlust tarneahelas ning varude liike ja juhtimise süsteeme. Kolmandas peatükis koostatud varude juhtimise mudel 2020. aastaks, kasutades varude tasemete arvutamiseks tellimuspunkti valemit S&OP plaani nõudluse kogustega, andis kohese säästu laoväärtuses 17,9 % ning kiirendas laokäibeväldet 3 korra võrra. Rakendades mudelit samade perioodide tagant muutub kitsa tarneahela varude juhtimine täpsemaks ning sääst ja toodete käibe tootlikuse kiirus veelgi. Mudeli täiustamiseks jäid lahti kaks teemat, mida võiks edasi uurida, reservvaru vajadus ning S&OP plaani ja reaalse nõudluse seosed. Need teemad aitaksid autori loodud mudelit veelgi paremaks teha. Viimasena tõi autor välja neli kitsa tarneahela täiustamise ettepanekut, mida saaks rakendada ka FLIRi globaalse tarneahela osades – sealt tulenev sääst rahas ja ressursi efektiivistamine oleks juba kõrgemal tasemel. Viimaks soovitab autor FLIR Systems Estonia OÜ kitsas tarneahelas juurutada loodud varude juhtimise mudel, uurida edasi kahte teemat, mis autor välja tõi ning teistes FLIRi tarneahelates rakendada autori poolt sobivaks tunnustatud ettepanekuid.The need to write this thesis was due to the growing importance of supply chain management in the world. Effective management and improvement of supply chains and their parts, as well as inventory management mapping, provide input to the company primarily for cost savings. The company on which the work is based - FLIR Systems Estonia OÜ is an important link in the global supply chain of FLIR Systems Inc., being the only manufacturer of certain products worldwide. The narrow supply chain discussed in this work is located between FLIR Systems Estonia OÜ and the central warehouse of the EMEA region. The paper describes this supply chain and maps the inventory management method in it. To achieve the goal of the work, the author analyzed the history of performance indicators of the narrow supply chain product portfolio and its inventory levels, as well as sales statistics from the central warehouse. The tool created to meet this goal is an inventory management model that makes inventory management in a narrow supply chain more accurate and coordinated with the S&OP plan. In addition, the author made suggestions for improving both the narrow and FLIR global supply chain. The resulting analysis was supported by a theory section in which the author addressed supply chain and inventory management and strategies, supply chain forecasting and demand, and inventory types and management systems. The inventory management model for 2020 developed in Chapter 3, using the re-order point formula together with S&OP plan demand quantities to calculate inventory levels, resulted in immediate savings in stock value of 17,9 % and accelerated inventory turnover by 3 times. By implementing the model at the same time intervals, inventory management in a narrow supply chain becomes more accurate, and savings and product turnover productivity rates become even more accurate. To improve the model, two issues remained that could be further explored, the need for safety stock and the relationships between the S&OP plan and real demand. These topics would help to make the model created by the author even better. Finally, the author outlined four proposals for improving the supply chain, which could also be implemented in parts of FLIR's global supply chain - the resulting savings in money and resource efficiency would be at a higher level. Finally, the author recommends to implement the created inventory management model in the narrow supply chain of FLIR Systems Estonia OÜ, to further investigate the two issues raised by the author and to implement the proposals recognized as suitable by the author in other FLIR supply chains

Formula student Fest18 uprights designing
No full textAntud lõputöös projekteeriti Formula Student klassi vormelautole FEST18 esi-ja tagakäänmikud. Käänmiku ülesandeks on ühendada ratas läbi õõtshoobade vormeli kerega. Samuti on käänmik ülekandekorpuseks, ning elektrimootor kinnitub käänmiku külge. Eesmärgiks seati projekteeida toimiv lahendus, mis oleks kergem kui eelneva aasta käänmikud ning peaksid vastu suurematele jõududele. Ühtlasi taheti lihtsustada ja kiirendada külgkalde seadistamisvõimalust. Esmalt kirjeldati Formula Student Team Tallinna poolt saadavaid lähteparameetreid ning ostutooteid mis peavad käänmikutega ühilduma. Selgitati mida peab ostutoodete puhul arvessevõtma käänmike projekteerimise käigus. Tootmismeetodiks valiti freesimine ning otsustati valmistada kõrgtugevast alumiiniumisulamist Alumec 89. Tootmisprotsessi silmas pidades asuti käänmike projekteerima raalprojekteerimis tarkvaras Catia V5. Kirjeldati uute lahenduste valikut ning nende vajalikkust. Uute lahendustena tuuakse välja ülemise õõtshoova kinnitus- , käänmike tagakaante kinnitus-, tagakaane tihendus- ja külgkalde reguleerimis plaatide disaini. Pidurisadulate kinnituskohad paigutati massikeskme alandamise eesmärgil nii madalale kui võimalik. Seejärel teostatakse käänmikele tugevusanalüüs LEM tarkvaraga Ansys R17.2. Kirjeldatakse käänmike analüüsi ülesehitamiseks vajaminevaid rajatingimusi ning analüüsitavaid olukordi. Lõpptulemusel eesmärgid täideti. Projekteeritud esikäänmiku kaal vähenes 0,039 kg ja tagakäänmiku oma 0.068 kg võrra, samas taludes suuremaid vedrustuse jõudusid. Rattakülgkalde reguleermine muutus mugavamaks ja kiiremaks. Antud vormelauto on läbinud esimesed testipäevad ning projekteeritud detailid on vastu pidanud. Kõik vedrustuse koostus olevad komponendid ühildusid projekteeritud käänmikega ning nende koostamisel ei esinenud probleeme. Autori arvates oleks võimalik käänmike kaalu alandada veel ülekandekorpuse arvelt, kui ülekannet optimeeritakse väiksemaks. Vedrustuse hoobade kinnituste arvelt seda teha ei oleks mõistlik, sest olulist kaaluvõitu sealt ei saavutataks.The following graduation thesis Formula Student FEST18 uprights designing target was to design uprights for Formula Student formulacar FEST18. Upright´s task is to connect wheel through the suspension link to the formula car´s body. Also the upright is drivetrain housing and electrical motor connects to it. The goal was to design a working solution that would be lighter than last year's uprights and would resist larger forces. At the same time, author wanted to simplify and speed up the camber adjustment. Firstly were described the design parameters and purchasing products, which must be compatible with the uprights. Explaind what purchasing products parameters should be taken in mind while designing uprights. Uprights were choosed to mill from high-strength aluminum alloy Alumec 89. The uprights were designed in Catia V5, in the view of the production process. The choice of new solutions and their necessity were described. New solutions are new upper suspension link monting, uprights backcovers mounting, backcovers sealing and camber plates desing. Brake calipers mountings were placed as low as possible to reduce center of gravity height. Then the strenght analyzes were done with the FEM software Ansys R17.2. Describes the basic structure of analyze and analyze situatsions for the uprights. The end result was fulfilled. The front upright´s weight dropped 0.039 kg and the rear upright´s 0.068 kg, while suppording the larger suspension forces. Camber adjustment went more comfortable and faster. The formula car has passed the first test days and all the designed items have hold on. All suspension components were compatible and didn´t face any problems while assembling them. In the author´s opinion, it would be possible to reduce upright weight from drivetrain housing if it would be more optimized. It would be not reasonable to reduce weight from the uprights suspension link mountings, since a significant weight loss would not be achieved there
Growth of rudd (Scardinius erythrophthalmus L.) in Saaremaa Karujärv and its part in the fish fauna
No full textKäesoleva bakalaureusetöö eesmärgiks on kirjeldada Saaremaa Karujärve kalastikku ja
roosärje kasvuparameetreid. Roosärge peetakse tööstuslikult vähetähtsaks kalaks, seega
teadusliku uurimisobjektina ei paku ta suurt huvi kuna roosärg on inimese toidulaual
vähetähtsusetu oma madala toiteväärtuse tõttu. Kuid inimesele suhteliselt vähetähtis kala
võib mängida olulist rolli Eesti ühe ainsa taimtoidulise kalana ning rõõvkaladele
toiduobjektina. Töös antakse ülevaade roosärje levikule, bioloogiale ja elutegevusele. Töös
võetakse kokku aastate 2002, 2008 ja 2014 katsepüügi käigus kogutud andmed ning
antakse ülevaade Karujärve olemasolevast kalastiku liigilisest koosseisust,
milles vaadeldakse roosärjele toidu/elupaiga konkurentsi pakkuvaid liike ning ka
roosärge toiduks tarbivaid liike.
Katsepüügil uurimismeetod on ühtne Euroopa standardne püügimetoodika EVS-EN
14757:2005 nõudest ”Water quality – sampling of fish with multi-mesh gillnets“.
Seirepüügil kasutati teadusotstarbelisi mitmesektsioonilisi Nordic tüüpi nakkevõrke.
Roosärje juurdekasvu arvutamiseks mõõdeti soomustel aastaringide vahed ning arvutati
valemi abil isendite iga-aastased juurdekasvud. Pikkuse tagasiarvutamiseks mingis kindlas
vanuses kasutatakse R. Lee valem valemit: Tln = Tlx(Rn/R) (Chugunova, 1959).
Olulisemateks tulemusteks oli Saaremaa Karujärve roosärje pikkuse kasvutempo ning
kaalu kasvutempo eripärad. Roosärje kasvutempo on kõige kiirem esimesel eluaastal ning
aeglustub vanuses 11+. Töö autori andmete põhjal asendub pikkuskasv Saaremaa
Karujärves kaalkasvuga vanuses 10+.The goal of this thesis was to describe the growth parameters of rudd and the fish fauna of
Saaremaa Karujärv. Rudd is considered to be industrially inessential fish, which means it
does not pose as an interesting subject for scientific research, because it does not play an
important role in people's food table for its low nutritional value. At the same time this fish
expendable for people plays an important role as one of the most phytophagous Estonian
fish and as a feeding object for carnivorous fish. The distribution, biology and life
activities of rudd are reviewed in this thesis. The collected fata from 2002, 2008 and 2014
research catches are summarized and the present composition of species in Karujärv are
surveyed. Based on this, a review on species, which compete with rudd for food and
habitat and which consume rudd as food themselves, is made as well.
The research method of the experimental fishing is applicable wit European standard
fishing methodics EVS-EN 14757:2005 requirement ”Water quality – sampling of fish
with multi-mesh gillnets“. Multisection Nordic gillnets for research purposes were used
during the experimental fishing. The radius length of the annulus of lagenar was used to
determine the increment of rudd and to calculate the annual growth of specimens. To
calculate the growth in length during a specific age R. Lee formula was used: Tln =
Tlx(Rn/R) (Chugunova, 1959).
The most essential results are the rate of the growth in length and weight of Saaremaa
Karujärv rudd. The rate of growth of rudd is fastest during the first year of life and slows
down after the age of 11+. By the data gathered by the author of the thesis, the growth in
length substitutes with the growth in weight in the age of 10+
Aspects of the social geography of the province of Sistan/Baluchestan, Iran
No full textThe Kordi (Kurd) tribe now living in Iranian Baluchestan would appear to be an offshoot of the far more numerous Kurdish peoples of the north-western Zagros Mountains of Iran-Iraq. The Kordi were settled in their present location possibly in the l6th Century AD, but much more likely in the l8th Century, originally to act as tax-gatherers on behalf of the Shah-in-Shah. For many years they lived as pastoralists (often nomadic), tax gatherers, guardians of the frontier, and by raiding and plunder. Their habitat, round the Kuh-e-Taftan massif (one of the more fertile areas in the extremely arid and topographically difficult region of Baluchestan) allows some agriculture; and since the 1940's especially, the Kordi people have turned increasingly to a settled way of life based on mixed farming - mostly cultivation, with some animal herding. The thesis examines the origins of the Kordi, their geographical environment, social organisation and demography; and considers present and future evolution of this people in a changed and changing Iranian State
Integrated Design of Museum's Indoor Climate in Medieval Episcopal Castle of Haapsalu
No full textAbstractThe ruins of medieval Episcopal Castle of Haapsalu in Estonia are planned to be taken into use as a museum. Due to conservational, architectural or economic reasons, it is difficult or sometimes also impossible to install climate systems into historic buildings. Before the design process, indoor climate measurements have been carried out to get an overview of the current situation, the needs for changes, to get data for model calibration and to work out the design strategy. Combined heat, air, and moisture simulations were performed with IDA-ICE software together with different indoor climate control strategies and different outdoor climatic conditions (typical year, warm summer, cold winter, humid autumn). The interaction of indoor air and moisture performance of building envelope was taken into account. Simulation model was calibrated based on field measurements and the results of simulations showed reasonable agreement with field measurements. By simulations, different climate control systems were analyzed and their necessity and the extent of performance were determined. The main target is to find out capability of passive measures for climate conditions to avoid active drying and humidifying.Resultsshowed that: with only passive indoor climate measured the indoor climate is strongly dependent of the outdoor climate as well as the massive limestone walls with large thermal and moisture capacity. Without indoor climate systems there is extensive indoor temperature and relative humidity fluctuation throughout the year. To ensure suitable indoor climate, room heating, humidification during winter period, and dehumidification during summer and autumn periods is needed. It was difficult to provide strict required indoor climate conditions for museums through the year only with passive measures
Penyuluhan perilaku hidup bersih dan sehat (oral hygiene) di Sekolah Pendidikan Anak Usia Dini Ayah Bunda Sayang, Lombok Barat
No full textThe mouth and teeth are one of the entry points for microorganisms such as fungi, bacteria and so on which can cause health problems. Oral and dental health can be achieved by implementing clean and healthy living behaviors (PHBS) oral hygiene such as brushing your teeth properly and being able to keep your toothbrush clean. This community service activity aims to increase the knowledge of young children regarding the practice of maintaining oral and dental health. The method of activity that the author uses is in the form of counseling and mentoring with lecture methods, discussions, and demonstrations on how to brush your teeth properly and correctly. This activity was attended by 16 participants. The player is accompanied by the teacher to fill out the questionnaire. The results of the questionnaire showed that almost of the PKM participants had not properly implemented the behavior of maintaining oral and dental hygiene. Participants took part in this counseling enthusiastically and the results of the evaluation revealed that all participants understood oral hygiene behavior, namely knowing the practice of brushing their teeth and how to maintain cleanliness in brushing their teet
現代日本人の歯髄腔形態の分析, とくにTaurodontismについて
No full textThis article concerns with an anthropological investigation of pulp cavity morphology of the molar teeth in the modern Japanese. The author proposed a five-class classification method of the pulp cavity morphology which was modified from that presented by Shaw （Figure 2）. The results obtained are as follows: 1） No hypertaurodonty was observed in lower molars of the Japanese. 2） The basic form of the pulp cavity of M1 appears to be a cynodonty seen from the evolutionary point of view. 3） There is an apparent trend in M2 in which the pulp cavity changes from hypotauroclont.y to cynodonty with increase of ages. However, since this change is relatively slight, the shape of the pulp cavity seems to be relatively stable in this tooth. 4） On the contrary to M1, hypotaurodonty appears to be the basic form in M3. 5） Generally in the lower molars, the frequency of hypercynodont is higher and that of mesotaurodont is lower in the higher age groups. 6） No between-sex difference of this trait is observed in M1. On the other hand, in M2 and M3, a trend towards taurodont is a little more apparent in females than in males when all the age groups are combined. 7） The relative size of the pulp cavity shows the relationship of M1 ≦ M2 M3. 8） In case of personal identification from the pulp cavity morphology, M1 and M2 must be observed in combination, and detailed observations of hypertaurodont should be clone. 9） The internal morphology of the human teeth, or that of taurodont in particular, is a character of quite importance in relation to the external morphology of the teeth. This is especially true when the teeth are investigated from the evolutionary point of view. At the sametime, the author recommends the method of classification proposed in this article to evolutionary studies of the human teet
