Desorption characteristics of waste activated carbons collected from chemicals manufacturing industries in Shiwha/Banwal industrial complex were investigated. Activated carbons were decomposed in a thermogravimetric analyzer (TGA) at 513K with heating rate of 10 ℃/min under nitrogen atmosphere. Activation energies and reaction orders for desorption, from the waste activated carbon were estimated by employing Friedman method and Freeman-Carroll method. It was found that the reaction orders of desorption in waste activated carbons were 0.27-1.69, and activation energies were 15.2-45.7 kJ/mol in Friedman method and 13.7-17.1 kJ/mol in Freeman-Carroll method.

The study focuses on analysing situation of disasters and characteristics in construction process which the technical construction firms accomplish. Besides, the study aims at the role and responsibilities of technical construction firms in construction safety. It is found out by a questionnaire and interviews in this study that safety control and management have a key role to prevent accidents in construction projects. Based on the result of the research, it is concluded that institutional improvement and support strategies are suggested and that additional to the support of the government and institutions in charge of the field of construction safety the effort of the first contractor, the second contractor and the laborer it is also important.

when adopting and implementing GHS system in Korea and to draft the revision proposal for Industrial Safety and Health Act taking into account of unique domestic situation. The research method is to conduct a survey for 2 month period from early April to late May in 2006 to 830 randomly selected chemical manufacturing, importing and exporting, and consumption companies out of all the companies surveyed by the Ministry of Labor under 2004 Work Environment Status National Survey. A total of 610 survey was collected and analyzed. The results of this thesis is summarized as follows , First, based on the survey analysis it is vital to conduct a national PR using pamphlet, internet, and daily newspaper and to provide technical assistance such as training expert and publishing GHS manual by expert organization such as Korea Occupational Safety and Health Agency (KOSHA) for early settlement of GHS in Korea. Second, it is also needed to give a grace period of 1 to 2 years to minimize the dramatic impact for industry, to encourage the establishment of the GHS team utilizing safety managers within companies, and to develop and distribute the standard GHS software by government. Third, taking into account of difficult situation of small companies, KOSHA needs to provide a full technical and financial support for companies with less than 100 employees and especially for chemical manufacturing companies. Fourth, it is also needed to operate an Interministrial GHS Committee (IGC) involving 7 related ministries for smooth GHS implementation and to develop an infra by sharing responsibilities among related ministries and establishing internationally recognized organization for hazard classification, labelling, and MSDS.

지속가능한 발전과 관련된 새로운 패러다임이 우리사회가 도달해야할 목표로 간주 되고 있다. 물류는 자원순환형 시스템의 실행역할을 하고 있으며, 지속가능발전을 위해서 환경친화적으로 구축되어야 한다. 최근 물류분야에서도 환경이 중요한 경쟁수단으로 등장하고 있어서 이에 대한 연구가 필요하다. 이에따라 본 연구는 물류활동 중에서 수송활동과 포장활동을 중심으로 어떻게 환경친화적으로 수행하고 있는 지를 기업의 사례를 통하여 살펴보고 방향을 제시하고자 한다. 이를 위하여 198사를 대상으로 77개 항목에 대하여 조사하였으며, 이를 바탕으로 기업들이 추진해야할 환경친화적 물류활동의 추진방안을 제시하고자 한다.

Ten years have passed since the establishment of KOSHBA(Korea Small and medium enterprises Hybrid Business Association). KOSHBA is composed of over 400 regional groups; over 6,000 enterprises are participating in the association. To become a dynamic and vital association, it is necessary to share, learn, and discuss their managerial problems based on mutual trust and respect at the regular monthly meeting.

In this study, the removal efficiency of 24 odorous compounds was measured in diverse control process units of 7 individual chemical companies located in Ban-Wall & Shi-Wha Industrial Complex in Gyeonggi-do, Korea from March to August, 2007. To quantify the removal efficiency rates of major odorous compounds, we collected odor samples from the inside process and both the front and rear side of 7 control process units. As the results of this study, it was shown that toluene, ammonia, trimethylamine (TMA) and acetaldehyde were dominant odorous compounds in the inside process. In addition, VOCs, TMA and acetaldehyde were also detected at higher concentrations in the stacks and 10 (toluene, acetone, ethyl benzene, xylene etc.) out of 24 index compounds were found to have negative removal efficiencies. According to the removal efficiency evaluation of seven odor control facilities, a company equipped with two connected absorption processes was shown to have positive (＋) removal efficiencies for 16 odor substances and NH₃, TMA, acetaldehyde, the priority odor substances, which meant the proper control system was installed and operated. Hence, to obtain best removal efficiency of odorous pollutant emission, the database on source characteristics and the development of management techniques of diverse control process units are continually needed.

The 5 working day's a week increase to fixed cost. Specially, the small & medium size company more increase to manufacturing cost. The introduction of 5 working day's rule influence to labor cost in manufacturing cost. Also, it make disappearance to fixed cost of 0.5 working day. Almost manufacturing company expect to have difficulty in product cost. The case of japan, many manufacturing company move to Asian countries after introduction of 5 working day's a week rule. The purpose of this study are the analysis of change product cost and suggest to solutions of productivity for a type of industries..
