본 논문은 재구성가능생산시스템 환경에서 e-MarketPlace를 통한 거래상황을 도입한 주기적 검토 재고모형을 연구한다. 의사결정권자는 고객의 확률적 수요를 만족시키기 위해서 생산용량/생산량을 확장/축소하거나 e-Marketplace를 통해 긴급으로 재고를 보충/처리한다. e-MarketPlace로부터의 거래 시 재고의 보충/처리에 걸리는 리드타임은 시스템의 생산리드타임보다 짧지만, 단위거래비용(구매/판매비용)은 생산용량/생산량을 한 단위 확장/축소하는 비용보다 높기 때문에 각 대안들의 비용-리드타임간의 trade-off가 고려된다. 추가적으로 e-MarketPlace로부터 재고를 보충하거나 생산용량을 확장하는 경우 그 수량에 따른 규모의 경제를 고려하기 위해 고정 비용이 포함된다. 우리는 제안되는 모형의 최적 정책형태를 규정하기 위해 동적계획모형과 K-convexity 기법을 적용하고, base stock policy와 (s,S) type policy의 조합으로 구성된 최적 생산-재고관리 정책을 제시한다.

Inventories of finished products exist in each stage of the channel between production and consumption. An inventory has several functions, which make it possible to produce by economic lot size and to elevate services for consumer by shortening delivery time, etc$\cdots$. Finished products may be inventoried in delivery-center as well as at the plant where production takes place. So, finshed products must be dealt with as multistage inventory problem, because an inventory functions differently according to its place. The purpose of this study is to determine how much to carry in stock and what stage to carry Though there may be several channels between production and consumption, this study deals with only one main channel, that is, series of ncomponents and determines the optimal inventory policy by introducing the concept of selling probabilities.

People in the Ancient Society of Korea liked golden earrings. The Royal Family or the nobility wanted to make more splendorous golden earrings in order to display their high-ranking positions. However, appearances or production methods of golden earrings differ a little by countries, for example, Goguryeo, Silla, Baekje, Gaya, etc. Therefore, by closely examining articles discovered from tombs, we can know which country they were from. In particular, earrings of Goguryeo and Silla are similar to each other while those of Baekje and Gaya are similar. This would be closely related with political relationships between the two countries. The shape of golden earrings in the middle of the $5^{th}$ century A.D. is relatively simple. However, since the latter half of the $5^{th}$ century, golden earrings in the Ancient Society of Korea changed in the direction of long length or significantly splendorous surface decoration. Accordingly, we can estimate the period of production by analyzing golden earrings discovered from a tomb. In addition, the above trend was common all the earrings in the Ancient Society of Korea, which implies that each nation closely exchanged reciprocally at that time.

The standard of agricultural mechanization is one of the important indicators for measuring the realized degrees of agricultural modernization in some regions. The Pearl river delta is most fertile, and thereby reputed as a land of fish and rice in the province. Studying the proceedings, profits and experiences of agricultural mechanization in the region obviously possesses the generally guiding significance for Guangdong to realize agricultural modernization by the year 2010. this paper involves these fields such as duainage, irrigation, harrowing, harvesting, transportation, processing and etc, in the Pearl River Delta, Results show as follows: (1) 80% work load in main production links has been mechanized ; (2) changed took place in traditionally agricultural production means and ways so took place in traditional agricultural production means and ways so that individual farmer in this region became commercial producer and then march toward commodity production of moderniza ion with high yields, good guality and high profits ; (3) further taping production potential to improve land output and labour productivity. Results also show that the degrees of agricultural mechanization in the Pearl River Delta are closely related to government' spolices, finance, moderate land scale management, rural industrialization and machine utility as well as talent training, shortage of which will surely; affect the proceeding of agricultural mechanization. Therefore, government must be urged to guarantee it by preferential policies and financial loan so as to greatly run rural industry, to create conditions for land scale management, to set up the socialized service system of agricultural mechanization, to actively train scientific talents and to introduce advanced equipments and technology from aborad in order to quicken the progress of agricultural mechanization in this regions.

This paper explores whether there is correlation between consonants' place and duration of adjacent vowels in English and Korean. The results showed that in English the vowels preceding alveolar stops were in general longer than the vowels before bilabial or velar stops. Consonants appeared to have their inherent length due to their place and to exhibit some compensatory effects on the duration of preceding vowels. This effect can be explained in a physiological term that the tongue tip is the organ which might be more agile in articulatory movement than the tongue body for the velars or the lower lip (and the jaw) for the bilabials is and the shorter production time of the alveolars caused the lengthening of the adjacent vowels. However, this physiological account did not hold in the case of Korean, which exhibited less consistent patterns across speakers for the consonants' place and the vowel duration. The segmental duration seemed to be timed quite consistently within a language but the pattern was not universal across languages.

근영 및 근중 등 원료삼의 품질에 관한 전통요인 7개를 새로운 요인인 화학성분 및 약리효과와 관련하여 검토하였다. 그 외의 요인인 산지는 이들 여덟가지 요인의 종합결과라고 볼 수 있다. 산지의 중요성은 상지에서 최우수원료삼이 생산된다는 것을 의미한다. 의약용 제품의 품질규정에 원료삼의 품질은 거의 기재되지 않고 제조에 의한 변화만 기록되어있는데 이것은 원료삼 품질을 무시해서가 아니고 원료삼의 전통적 방법에 의해서 공급되기 때문이다. 분석적 사고에 익숙한 세대를 위하여 약전에 원료삼 품질을 표기하는 것이 바람직하다. 제품의 품질관리를 유효성분이든 지표성분이든 성분에 의하여 한다면 여러 가지 성분의 구성비가 가장 좋을 것이다. 전통품질요인에 필적할 물리화학적 품질기준의 확립이 필요하며 이를 위하여는 여러 산지와 생육조건에서 생산된 원료삼의 비교연구가 필요하다. 제품에 산지와 원료삼 등급을 표시하는 것은 소비자들에게 올바른 정보를 줄 것이며 성가도 높아질 것으로 생각된다.

The purpose of this study is to provide the fashion industry in Korea with materials that could enhance its international competitiveness by suggesting marketing strategies for fast fashion brands after taking product, price, place, and promotion into consideration. The product strategy should focus on developing products that accurately reflect the general market trend and consumer demand, selecting optimal materials, and pursuing internal production. This, coupled with strategic cooperation with designers, will ensure reliable quality and enhance the brand image. The pricing strategy should place greater emphasis on reducing production costs. Diverse task outsourcing and design competition, for instance, can lower the cost of design development. The place strategy should be set according to the operation of a systematic and efficient distribution system based on SPA, an automatic delivery system, sales or return system, speed control system, and a value chain that consists of horizontal business alliances. The promotion strategy should be run under the central control of the headquarters using various unique VMDs. Furthermore, online marketing campaigns, spectacular fashion shows, design competitions, catalogue marketing campaigns, and other new sales promotion schemes could all be introduced.

The aim of this study is to empirically examine fundamental factors that drive FDI to a particular location. This study further explores operating conditions of Korean firms in Myanmar. A survey methodology and then a regression analysis are employed. The study finds that the factors such as transportation, production factor, market, and cost play an important role for the location of FDI. However, the Korean investment in Myanmar decreases from 2013. The decrease of Korean investment implies that investing in Myanmar has not been profitable. The empirical study finds a complicated pattern of FDI. Large Korean firms are located far from the consumer market, thus, bear an increased transport cost to reach the consumer market. They are rather located in a place where they can access to a transport means and raw materials with low cost to export final products. They place FDI into a host country to serve as a production platform for exports to neighboring countries.

To survive in the current shipbuilding industry it is of vital importance for shipyards to achieve an optimal utilization of resources, make an achievable planning and ensure that this planning is kept. Possible problems should be eliminated before production starts and if unexpected disturbances occur in the actual production the right measures should be taken. Due to the dynamic nature of the production process, the continuous variation in products and the complexity of both, all this can hardly be achieved with conventional static planning and analysis systems. Simulation provides a solution here, since this enables the modelling and evaluation of the dynamic relations between product and production process. After a global introduction to production simulation in general and the application of simulation at the Flensburger shipyard, this paper presents a tool that has been developed to simulate the various complex assembly processes taking place at shipyards. Subsequently the simulation model for the subassembly production at Flensburger, in which this tool is applied, will be discussed.
