한인수,Han, In-Soo 대한예방의학회 1974 Journal of Preventive Medicine and Public Health Vol.7 No.2
An observation on bacteriological conversion upon 56 bocteriological positives out of 131 cases of lepromatous leprosy treated by antileprosy morbile service was carried out. Those 131 lepromatous cases were a part of 335 total registered from three Guns of Gangjin, Hwa sun, and Goheung, Cheollanamdo, since 1957 to 1973 that has been under the control of antileprosy morbile unit. The results obtained are summalized as follows, 1. Lepromatous type was 36.9% of all cases. The ratio of male to female was 4.9 to 1. Age between 30-44, the most productive ages, occupied 38.0% and age over 60 occupied 18.0% of all. 2. 42.7% of lepromatous type was bacteriological positive. 43.1% was for male and 43.1% was for female. Age between 20 to 24 shown the highest positive at 63.7% and followed by aged over 60 (62.5%) and under 19 (60.0%). The lowest one was seen at age between 40 to 44 at 29.2%. 3. Bacteriological positive rate at registration was different in accordance with duration of treatment received befor registration. It came up to the highest 100.0% at the group treated one year before registration. That of the group not received any treatment was 56.4%, and the group received 4-5 years was the lowest at 26.1% 4. Bacteriological conversion rate was 44.6% and 14.3% of all positive casese regressed in bacterial number. 37.5% of all active cases converted bacteriologically within 5 years. 5. Bacteriological conversion rate in group received 1 year treatment before registattion was 66.6%. That in group not received any treatment was 31.8% and group received 4-5 years was 33.3%. 6. Considering of total duration reaseved treatment together with before and after registration, 33.9% of all active cases resulted bacteriological conversion or regression within 5 years.
플라스틱 소재의 고 변형률 인장특성 평가를 위한 홉킨스바(Split Hopkinson Pressure Bar) 측정 장비에 관한 연구

Split Hopkinson Pressure Bar (SHPB) is a general test equipment for measuring the mechanical properties of high modulus metal and composite materials at high strain rate. However, for the soft plastic material, it is difficult to hold the specimen and achieve dynamic stress equilibrium due to the weak transmitted signals. In this study, SHPB test apparatus were designed to measure accurately the high strain rate stress-strain curve of the soft plastic materials by changing the incident bar materials and the shape of the specimen holder parts. In addition, to verify the high strain-rate tensile strain data obtained from SHPB, the strain distribution of the specimen was measured and analyzed with a high-speed camera and the digital image correlation (DIC), which was compared with the strain history measured from SHPB.

본 연구에서는 벌크 중합법을 이용한 폴리스티렌 중합공정의 폭주반응에 대한 열적 위험성을 가속속도열량계(ARC)와 소규모 반응열량계(MM)를 이용하여 평가하였다. 당해 중합공정은 반응온도 120 ℃~ 130 ℃로 운전되어져야 하며, 130 ℃ 이상의 반응온도에서는 반응 생성물의 급격한 점도 증가로 인하여 반응기의 온도제어 실패에 따른 폭주반응의 위험성이 존재하였다. 또한 당해 중합공정의 반응온도(120℃ ~ 130 ℃)에서 공정운전 초기에 반응기의 냉각실패가 발생할 경우 폭주반응으로 인해 반응기의 온도와 압력이 각각 30 ~ 50분 이내에 약 340 ℃, 5.3 bar 까지 급격히 상승하여 반응기의 파열판이 파열되거나 반응기가 폭발할 수 있는 열적 위험성이 높게 나타났다. The aim of this study is to assess thermal hazards of polystyrene polymerization process by bulk polymerization with accelerating rate calorimeter(ARC) and Multimax reactor system(MM). From this study, we found out that the polymerization process should be operated at reaction temperature of 120 ℃ ~ 130 ℃. At reaction temperature over 130 ℃, there was a runaway reaction hazard due to the temperature control failure following a viscosity increase of reaction products. With a cooling failure of a reactor in the early stage of process operation at the reaction temperature (120℃ ~ 130 ℃), there was a high thermal hazard of burst of a reactors rupture disk or explosion of a reactor caused by the rapid rise of temperature and pressure to 340 ℃, 5.3 bar respectively within 30 - 50 minutes.

본 연구는 연구개발조직의 창의적이고 혁신적인 연구 성과를 창출을 위한 팀 창의성 영향 요인들을 살펴보는 것이다. 먼저, 구성원 개인 창의성, 팀 다양성, 팀 자율성 등의 선행요인들이 팀 창의성에 미치는 영향을 알아보았다. 둘째, 이들 선행요인들과 팀 창의성의 관계에서 팀 효능감의 매개효과를 살펴보고자 하였다. 셋째, 이러한 팀 창의성과의 관계에서 임파워링 리더십의 조절된 매개효과를 통합적으로 검증하고자 하였다. 이를 위해 본 연구에서는 5개 R&D조직에 종사하는 연구팀을 대상으로 설문조사를 실시하여 521명의 자료가 가설검증을 위해 사용되었다. 주요한 분석결과는 다음과 같다. 첫째, 팀 구성원 개인 창의성은 팀 창의성에 긍정적으로 유의한 영향을 미치는 것으로 나타났다. 둘째, 매개효과 분석에서 팀 효능감이 팀 다양성 및 팀 자율성과 팀 창의성간의 관계를 유의하게 매개하는 것으로 나타났다. 마지막으로, 임파워링 리더십의 조절된 매개효과 분석에서, 팀 자율성이 팀 효능감을 통해 팀 창의성에 영향을 미치는 간접효과가 임파워링 리더십이 높을 때 더 긍정적인 것으로 나타났다. 그러나 이외의 다른 변인에서는 조절된 매개효과가 발견되지 않았다. 이러한 연구결과를 토대로 이론적·관리적 시사점 도출 및 연구의 한계 와 미래의 연구방향을 제시하였다. This study first attempts to investigate the influence that a variety of antecedents, including creativity of individual team members, team diversity and team autonomy have on team creativity for the creative and innovative output in the R&D organizations. Second, it intends to investigate the mediation effect of team efficacy in the relationships established between the antecedents and team creativity. Third, it aims to verify the moderated mediation effect of empowering leadership that occurs in the relationship between the antecedents, team efficacy and team creativity. In this study, a survey has been carried out on researchers working in five R&D organizations where 521 individuals of 102 teams have been selected for the final analysis. The results of this study are summarized as follows. First, creativity of individual team members had a positively significant influence on team creativity. Second, the analysis on the mediating effect demonstrated that team efficacy possesses certain positive qualities in mediating the relationship between individual creativity of team members, team diversity and team autonomy on team creativity. Finally, in the moderated mediation effect analysis of empowering leadership, the indirect effect where team autonomy influences team creativity through team efficacy was more positive when the empowering leadership was high. However, in the rest of the variables, no moderated mediation effect was found. Based on these results, the study also examines the implications of the research in theoretical and managerial perspectives, as well as possible limitations that it may bear, according to which several suggestions are made in regards to the potential direction of future research.
