This study investigated the quality characteristics of factory-style ssamjang (FSS) and commercial handmade-style ssamjang (HSS) products. Moisture, crude protein, and crude fat contents were significantly higher in the HSS groups (49.37~62.12%, 9.39~13.46%, and 4.40~8.35%) than the FSS groups (41.94~45.83%, 7.50~9.09%, and 1.81~3.36%). Salt content was higher in the HSS groups (6.33~11.18%) than the FSS groups (6.10~7.57%). Moreover, the average salt content (7.51%) of the HSS groups and the FSS groups was lower than that of commercial ssamjang (8.73%). Hunter's color value was also significantly higher in the FSS groups. However, free sugar, organic acid, and free amino acids contents varied greatly between the FSS groups and the HSS groups, which was likely due to the different manufacturing method, ripening degree of doenjang and the main material used for ssamjang.

In order to construct an information pool on the production characteristics and efficiency of Korean railroad industry, various alternative approaches have to be applied. In this paper we present an empirical application of the distance function to measure the technical efficiency and the production characteristics of Korean railroad industry, The distance function firstly introduced by Shephard (1953) provides the advantage that it does not need information about prices, so it can accommodate the multiple output nature of the railway only using the quantifies as data. This is of great relevance in the context of the public sector such as railroad industry where there are often distinct control mechanisms on input prices. Also the distance function allows us to obtain a measure of technical efficiency as well as a measure of production characteristics. From annual data on Korean railroad industry during 1964-2004, multiple output distance function is estimated using quadratic programming model. The resulting technical efficiency estimates has tended to be improved over the period $1980{\sim}2004$. The indirect Morishima elasticities of substitution indicate that the substitutabilities for labor are relatively very low or impossible. The average scale elasticity is 2.7 which means that increasing the scale by 1per cent will result in an output increase by 2.7 percent. This result indicates that economies of scale are present in the Korean railroad industry.

우리나라 신발산업에서 중요한 위치를 차지하고 있는 부산 신발산업의 재구조화 과정을 도입기, 대량생산기지로서의 성장기, 구조 조정기, 네트워크 생산체제의 정착기 등 네시기로 구분하고 시기별 특성을 요약하면 다음과 같다. 첫 번째 시기는 1920년대 신발산업이 부산에 도입된 이후부터 1960년대까지이다. 이 시기의 주요 생산품은 고무신류이며, 소수의 대기업에서 대량의 저임금 남녀노동력을 고용하여 기업조직 내에서 일괄대량생산이 이루어졌다. (중략)

"Charmdlerak" a new high-quality Korean wheat, was produced with production management from the Rural Development Administration (RDA). We evaluated the characteristics of grain, flour, and end-use quality of "Charmdlerak" wheat to assess consumer satisfaction with this new variety of wheat. Eighty-two farmers (450MT/100 ha) in Gwangju metropolitan city produced Keumkangmil wheat and 23 farmers (30 ha) produced "Charmdlerak" wheat "Charmdlerak" wheat had 1.55% ash content and 11.0-13.0% protein content "Charmdlerak" flour was milled by a commercial machine in Samyang Milmax. The protein content of "Charmdlerak" was slightly higher than that of flour from Hard Red Winter Wheat (HRWW), the most popular multipurpose flour in Korea. The ash content and color of "Charmdlerak" wheat were similar to those of HRWW. End-use quality testing of cooked noodles and bread indicated that "Charmdlerak" flour resulted in softer noodles and similar bread loaf volume compared with products made from Keumkangmil wheat.

The purpose of this paper is to examine the spatial characteristics of the medical device industry in accordance with the promotion of regional industrial policy. For this aim, I suggest a research methodology that can examine the productivity of production activity and the profitability of sales activity by the government. As the government's large-scale support is localized by the 'selective support' method, the spatial characteristics of the productivity and profitability of the industry are different. In this context, the results of the review of the government's regional industrial policy in three aspects are as follows. First, the government's support did not come down to increased productivity and profitability. Second, high productivity at the regional level did not necessarily lead to high profitability. Finally, the high market share in terms of profitability did not guarantee high profits. Therefore, it is necessary for the government to reconsider the direction of regional industrial policy so that the link between productivity and profitability can be secured in the examination of the achievement of industrial specificity and policy support.

The continuing enlargement, deepening integration of EU and penetration of extra-EU enterprise into EU market are forming a new geographical restructure of the production system. In this paper, I analyse the changing geography of the EU automotive production system. The globalization and regionalisation of production activity intensify a competition among the enterprise. The European automotive production system changes to a platform system and a modular system for a diminution of productive costs, a development of various products and a frequent innovation of products. The European automotive enterprise is restructuring geographically the production functions and products in order to promote efficiency on a new production system, enlarged production space and intensified economic integration. The European automotive industry tends to a spatial specialization and agglomeration according to the locational factors of production functions and products and the locational condition of regions. This intensifies the geographical hierarchic structure of production activity between the core and the periphery.
