  • Purpose - The purpose of this study is to investigate economical ventilation effectiveness to reduce hazardous materials exposure and damage of workers by analyzing exposure amount of noxious substances under various ventilation conditions of nail salon for indoor environments. Research design, data, and methodology - This study was carried out with cooperation of Nail shop located in SeongNam city to involve an analysis of the environmental impact indoor air quality, pollutant exposure and economical cost-effectiveness in the nail workplace. The hazardous substances were PM-10(Particulate Matter-10㎛), VOCs(Volatile Organic Compounds) and Formaldehyde, which are the major materials of nail workplace. Results - PM-10 is reduced by about 60% with air cleaner, forced artificial ventilation by 32%, and natural ventilation by about 12%. TVOCs and Formaldehyde showed similar efficiency (80~100%) after natural ventilation and ventilation after 60 minutes. The removal efficiencies of VOCs and formaldehyde were similar to those of natural ventilation and mechanical ventilation system. However, in case of dust, natural ventilation was reduced by artificial ventilation system due to inflow of external dust during natural ventilation. Conclusions - If the pollution degree of outdoor air is not high, air volume is high, and natural ventilation is performed when the air conditioning and heating system is not operated. Even at the end of the work, it keeps operating for 60 minutes to remove the pollutants generated. Results of this analysis demonstrated that the worker environment can be improved by adopting institutional legislation and guidelines for ventilation.

  • PCB(Printed Circuit Board) 제조공정에서의 수율은 제품의 원가와 품질을 결정하는 중요한 관리 요인이다. PCB 제조공정은 일반적으로 많은 단계의 미세공정을 거쳐서 제품인 칩(Chip)이 생산되기 때문에 높은 수율을 보장하기가 현실적으로 어렵다. 제품의 수율을 향상시키기 위해서는 저수율의 원인이 되는 불량요인을 분석하고, 불량요인에 영향을 미치는 중요공정 및 설비를 찾아서 관리해야 한다. 본 연구는 로지스틱 회귀분석 및 변수선택법을 이용하여 혐의공정 및 설비를 찾는 방법을 제안하였다. 데이터는 실제 현장의 로트 데이터를 사용하였고, 각 로트는 진행한 설비 및 불량유형별 불량수를 갖고 있다. 또한 분석 결과는 실제 현장 확인을 통하여 수율에 미치는 영향을 확인하였다.

  • The goal of this study was to investigate the impacts of customer satisfaction, store image, and switching barrier on store loyalty of the clothes shops at a large-scale discount store. The subjects were 357 female adults living in Suncheon City, Jeollanam Province. The questionnaires were conveniently sampled from June 1 to 30, 2006. The collected data were factor and reliability analyzed using the SPS program. And LISREL was used to test and evaluate the relationships between the constructs through confirmatory factor analysis and covariance structure analysis. Among the six hypotheses set in the research model, total four were selected through empirical analysis and the rest two were rejected. The analysis results were useful in making a conceptual model that could keep the simplicity about store loyalty and had increased explanatory power. Thus it turned out the deciding factors of store loyalty for the clothes shop at a discount store were customer satisfaction and switching barrier rather than store image. Customer satisfaction had the biggest influences on store loyalty among the expected variables. Considering the direct impacts of switching barrier on store loyalty, it's important to work on switching barrier along with customer satisfaction in order to maintain the customers' store loyalty. The efforts to identify the various factors of store loyalty in addition to switching barrier, customer satisfaction, and store image will lead to such marketing strategies as can vitalize the clothes shops at a large discount store.

  • Since Deng Xiaoping's implementation of the "One China, Two Systems" policy, mainland China and the other Chinese regions of Hong Kong and Macau have cooperated in various ways to work towards successfully developing China's overall economy and industries. Particularly, cooperation between Guangdong Province and adjoining Hong Kong have been contributing to China's development, and this study explores their industry conditions including their current two governments policies designed to promote collaboration. The two partners were in a cooperative relationship even before the handover of Hong Kong, beginning with a "front shop, back factory" model built on their respective comparative advantages in labor-intensive industries in the 1980s. This cooperation effectively propelled the Pearl River Delta Region's industrialization process and enabled Hong Kong to transform from a manufacturing industry-based economy to a service industry-based economy. From the early 2000s, Guangdong and Hong Kong diversified their collaboration project from culture to high-tech. Also, both authorities produced several types of policies not only to promote both industries but also to harmonize their two different economic levels and models. As a result, the Guangdong and Hong Kong economies have developed remarkably well during the past two decades and continue to form future plans that carry plenty of optimism. Nonetheless, this study showed discrepancies between engineers and scientists from the two areas in their perception of their technology and science cooperation. Hong Kong experts were more negative in their responses but noted some successes of the collaboration, while Guangdong's group showed overall positive responses. This difference results from an unbalanced role in cooperation. Hong Kong's side responds to cooperation plans and takes on leading roles with more frequency than Guangdong's side in actual cooperation project processes.

  • The purpose of the study lied on supporting the reeducation program which was focused on the demand with the clients by analyzing the recognition on the real situations of the reeducation on the hair designers in the nation. As a result on the subject, the responders said they could usually learn new information through the various seminars that were held by beauty product suppliers and companies, and most of the high school or under high school level designers have participated in various seminars while the designers who graduated from a junior college or universities had experienced new trends at life time education establishments(p<0.01). A hair designer who was single and paid low salary usually depended on the course inside the shop(p<0.01), and most of the information they got was through the suppliers of the beauty products. In that case, regular sources of information, such as educational establishments, informative magazines, Internet were highly recommended. A reason for unsatisfactory reeducation was due to lack of time and a reason for not participating the seminar was also due to time shortage caused by regular working hours, which was reflecting the real situation of the hair designers. As a suggestion for the reeducation establishment, most of the responders wanted vocational schools or life-time educational center. They wanted a fixed regular period for reeducation, especially over the weekend for after working hours. It means they want long-time systematic education. Considering the results, a course which is organized for a long-time systematic purpose is suggested for the hair dressers who want to be professionals in the field with the class equipped with contents of the classes, period, and place. For the purpose to be realized, improvement of the working hours in needed and it will be an incentive to make the hair designers satisfied with their work.

  • Purpose - In general, large companies have larger organizations, funds, and systems to provide more effective and efficient services in the market. However, development needs to support the livelihood of ordinary citizens who work for small businesses as well. This research suggests that a new distribution channel, called a "foothold style Kosa mart," that cooperates jointly with a distribution center and a large discount mart can provide direct solutions to small and mid-size distributors. This new distribution channel can achieve a limited type of "Nadle shop (small supermarket) foster project" related to building a joint distribution center and improvement in wholesale supply. Research design, data, and methodology - Data about the Korea distribution situation, the Nadle stores, and the logistics centers were collected from literature, Statistics Korea, journals, and reports. Specifically, we investigated information about Kosa Mart and Nadle stores. We focused on the redesign of the distribution center for the Nadle store. Results - The Kosa Mart distribution center now includes 18 warehouses, and has been handling 2000-3000 items. Most of the warehouses have been simply designed and items loaded and stored without refrigeration; thus, it is possible to store only products of certain manufactured goods. The current logistics center has no wholesale function because it failed to resolve the joint purchasing and product supply issues of competitively priced products. Conclusions - This study aimed to identify ways to strengthen the competitiveness of small- and medium-sized retailers. A Kosa Mart redesign aims to unifying the logistics center, stores, and customers. First, the joint wholesale logistics system, equipped with an integrated ordering system, needs to process customer orders and store orders at the same time. Second, excellent small business product development has to connect with production. Third, the store composition needs to support a shipping hub. Fourth, the Mart differentiates itself from convenience store goods by supplying regional and specialized products to customers. Fifth, a service buying agent and direct transactions between producers and consumers need to be established, and exhibits and displays of goods need to be improved.
