의류산업은 대표적인 노동집약적인 산업 중 하나로 의류 제조의 기본 공정인 봉제 작업은 인력에 대한 의존도가 매우 높다. 의류 생산비용은 라인의 효율성에서 큰 영향을 받는데, 생산비용의 절감을 위해서는 생산 속도를 조절하여 라인의 균형 유지하는 것이 중요하다. 그러나, 현재 의류 생산라인에서 활용되고 있는 인력에 의한 생산 실적 집계 방식은 이를 위한 부수적인 인력의 소요 등으로 인한 추가 비용이 소요되어 중소기업들이 직접 적용하기 쉽지 않다. 완제품의 인력에 대한 의존도는 집계 시간의 추가 소요와 인적 오류가 크게 잠재되어 생산비용의 증가와 함께 효율성의 저하를 초래할 수 있다. 본 논문에서는 에너지 소비 데이터를 수집하고 이를 CNN (Convolutional Neural Network) 기법을 적용하여 분석함으로써 재봉 작업을 통하여 생산한 제품의 수량을 추적하고 자동으로 집계할 수 있는 봉제 작업 생산 추적 시스템을 제안한다. 개발된 시스템을 통하여 2종의 재봉 작업을 테스트 한 결과, 최대 98.6 %의 정확도를 보이며 재봉 작업을 감지할 수 있었다. 개발도상국에서 의류봉제산업은 매우 중요한 산업이나, 위에 언급한 문제들을 해결하기 위하여 고가의 첨단기술을 적용하는 등 많은 자본을 투입하는 것은 크게 제한된다. 적정 기술을 적용한 본 기술은 이러한 개발도상국의 의류산업에 큰 도움을 줄 수 있을 것으로 판단된다.

In labor-intensive enterprise, such as garment factory, assembly line is widely used as a manufacturing process for reducing costs and production time. However, for the sake of the various working capacity of worker, idle or delay may happen and influence the rear processes. If these unforeseeable delay happened continuously, it may influence the whole manufacturing process and a model, which is called limited-cycle model with multiple periods (LCMwMP), is assumed to evaluate the influence risk. In order to minimize the risk, the assignment of the workers is focused on. In this paper, we deal with an assembly line as LCMwMP model when two kinds of workers exist, whose efficiency is assumed to two different groups. We consider an optimization problem for finding an assignment of workers to the line that minimizes total expected risk, which is exchanged to expected cost by reset model of LCMwMP. First, reset model as a simple model of LCMwMP is introduced. Then, some hypotheses of the rules of the optimal worker assignment are proposed and some numerical experiments are researched assuming the processing time as Erlang distribution. Finally, the other rules on other certain conditions are discussed.

As apparel manufacturers have increased their outsourcing garment making to cope with the rapid changing market, the information sharing has been the most important factor for the Korean apparel industry. The purpose of this research was to identify the properties and effects of information sharing system between Korean apparel manufactures and contractors. For this study, two apparel manufactures which actually used the information sharing systems were case-studied for the properties and effects of the information sharing system. The results of this study are shown as follows; 1) The companies ("J" and "S"), studied in this paper used sharing information mostly on order, delivery, and accounts within their contractors based on information sharing system. Company "J" turned out to have strong partnership with their contractors and developed more flexible manufacturing system and QR strategy. They shared not only basic transaction information but also quality inspection information and work-in-process information by using information sharing system. 2) The effects of information sharing system were proved as business transaction time reduced more than 60 percent, compared when staffs had to face to face, or use phone or fax to deliver documents. This study was investigated to provide an example which introduces information sharing system objectively and systematically to the apparel industry.

Studying employees' personality and relationship to their job would help to improve high unemployment and turnover rate in the current Korean fashion and textile industry. Based on personality which is an important influential factor, this research studied types of fashion and textile-related occupations and differences among employees' personalities related to the types. Using disclosed data from Korea Employment Information Service, 27 fashion and textile-related occupations were selected for the final analysis. Ward's Minimum Variance Cluster Analysis, MANOVA, and ANOVA by SAS 9.3 was used to analyze data. First, fashion and textile-related occupations were classified into three groups. Group 1 was mostly consisted of occupations related to manufacturing process of fashion and textile including mechanical technicians. Group 2 included occupations in garment designing and manufacturing. Designers and manufacturers including shoes, bags, and jewelry belong to group 3. Second, after observing differences in personalities among the three groups, group 1 answered that most of the personalities were not important for performance of their duties, group 2 said that only some of them were important, and group 3 regarded most of them as important. Specifically, group 1 considered precision as the most important personality but rest of the personalities not as necessary. It was revealed that personalities in relationship with other personnel such as sociality and leadership were not important. The results in this study will be used for analyzing whether job seekers' desired occupations in fashion field corresponds to their personalities and is expected to become a basic data of students' career counseling for educators.

This study aimed to systematize the apparel vendor work processes and provide useful information to future employees of clothing export units by analyzing the processes of vendors' manufacturing tasks. A survey of 20 apparel vendors servicing mainly U.S. buyers was conducted on employees of overseas business departments working for more than five years. buyers. Based on the results, vendors mainly manufactured cut-and-sew knit products. Regarding the production method, OEM was used more frequently than ODM. Fourteen (70%) companies used the ODM method. This suggests that vendors are expanding their production method from OEM to ODM. In order to summarize the work of each business based on the clothing production process research results, buyers were in charge of planning products and the vendors were in charge of sampling. Production of materials and the approval of material tests were out sourced. Overseas factories of vendors were in charge of bulk (mass) production and garment finishing, as well as packaging and shipping the completed products. Even though the vendors' head offices do not directly produce clothes, they play a pivotal role in ensuring planning and management progress in clothing production. As buyers prefer direct contracts for cost reduction, the vendor additionally performs the role of an agent. Also, with the increase in ODM production ratio, the work area of the vendor is expanding. If Korean clothing exporters improve their global competitiveness by investing in the R&D of materials and design to enhance the ODM method, the development of Korea's clothing and export industry will benefit significantly.
