N/A Background: Since asthma caused by toluene diisocyanate (TDI) was reported at a polyurethane paint factory, occupational asthma there has been increasing concern of in both allergic and occupational health. However, the statistics of occupational asthma did not reflected its seriousness because of many barriers related to legal reporting. Since fild a voluntary report from a clinician sent directly to a surveillance center would allow more cases to be filed without any disadvantage to workers and employers, we developed a surveillance system to facilitate the reporting of occupational asthma. Methods : Allergists and pulmonary physicians were asked to report to the Occupational Asthma Surveillance Center(OASC) using a mail, fax or e-mail if work-related asthma was diagnosed. A claimed case for occupational asthma to the Occupational Health Research Institute was also included. The OASC contacted the workers by phone and investigated the workplace if necessary. The reported cases from October, 1998 to November, 1999 were analysed. Results: Thirty-three cases were reported with 29 males and four females. The mean age was 44 and the mean latency period was 5.4 years. Twenty-one cases were caused by a known allergen inducer with objective evidence. The causative agents included TDI in 45.5 %(15), followed by reactive dye in 24.2 %(8). welding fume(2), formaldehyde(1), paint (1), toluene(1). styrene(1), exhaustive gas(1), and wood dust(1). Among these cases, there were seven dyers, four painters, three machine operators and furniture finishers, two assemblers and tanneries. Eighteen cases had claimed Workers Compensation Insurance and all were accepted. The reasons for not claiming Insurance included ignorance(28.5%), feat of job dismissal (23.8%), other reasons (9.5 %), agreement with the employer(14.3%) and employer hirnself(9.5 %) Conclusion : The OASC by allergists was an effective system to find unreported cases and to provide a prevention strategy of occupational asthma. Occupational asthma was mostly caused by TDI and reactive dye. Painters and dyers were the most common occupations causing occupational asthma. Only half of occupational asthma patients claimed compensation because of workers ignorance and fear of being fired. (J Asthma Allergy Clin Immunol 20: 906-15, 2000)

Korea, high-rise buildings are likely to cause fire hazards and property damage caused by many casualties and natural disasters. While scholars and experts are asking for solutions to this problem, we still consider the standard of a building to be complementary to the safety of a high-rise building. This is because the current law, such as the Building Act and the Fire Prevention Act, has not been enacted in particular. The purpose of the study is to provide safe housing in high-rise buildings in Korea. A focus on evacuation plans for fires classified as major risk items.

전기도금을 이용하여 구리 박막을 성장 시킬 때, 가속제가 미치는 영향에 대하여 조사 하였다. 구리 seed layer 위에 전착된 구리박막에 대해, 4-탐침법으로 표면저항을 측정하였고, 전착률 및 두께는 FE-SEM을 이용하여 측정하였다. 표면 거칠기는 AFM을 이용하여 측정하였다. 형성된 구리 박막의 불순물 유무는 XPS를 이용하여 측정 하였다. 전해용액(CuSO₄ㆍ5H₂O 40 g/ℓ, H₂SO₄10 g/ℓ , HCI 50 ppm), 유기 첨가제(억제제 2.5㎖/ℓ, 평탄제 2 ㎖/ℓ고정 하였을 때, 가속제의 첨가량이 증가할수록 전착률이 증가하였고 표면 거칠기는 감소하였다. 가속제의 첨가량이 6 ㎖/ℓ 일 때, 전착막의 비저항 값이 가장 낮았다. We investigated the effects of an accelerator on the growth of Cu films by electrochemical plating. Cu thin film were deposited by electroplating process over Cu seed layer. The sheet resistance was measured with a four-point probe. The deposition rate and thickness was measured by a FE-SEM. the surface roughness was measured by AFM. The impurity presence of the Cu thin film was measured by XPS. The plating electrolyte(CuSO₄ㆍ5H₂O 40 g/ℓ, H₂SO 10 g/ℓ , HCI 50 ppm) and organic additives (suppressor; 2.5 ㎖/ℓ , leveler; 2 ㎖/ℓ) were fixed. According to increase of accelerator, the deposition rate increased and the surface roughness decreased. The resistivity was the lowest when accelerator of 6 ㎖/ℓ is added

RSIF(Robot System integration Framework)는 Blackboard System과 Service Agent를 다루는 서비스 지향 아키텍쳐이다. 현재 RSIF에서는 서비스 지향 아키텍쳐의 특징 중 하나인 서비스의 발견 및 검색이 지원되지 않고 있어 상대방의 정확한 URL을 알 지 못하는 경우에는 서비스를 이용하기가 어렵고 서비스 에이전트의 등장이나 접속 여부 또한 알아내기 힘들다. 우리는 이를 해결하기 위해 서비스 에이전트들의 엘로우 페이지 역할을 해줄 서비스 에이전트를 구상하였고, 이를 구현한 후 실제로 시험해 보았다.

The diaphragms were used to protect the purity of hydrogen and to prevent the hydrogen leakage. In this study, the structural analysis of a Diaphragm were numerically evaluated under cavity radius and several pressure conditions. the analysis model is simplified by removing the needless part of compressor at the structural analysis. The diaphragms had two high stress zones : at the center of gas diaphragm and at the outside condour of oil diaphragm. The stress distribution of diaphragm is varied by cavity shape. The cavity shape is more important variable than the pressure applied on the diaphragm plane.
