정춘화 한국도서관정보학회 1995 한국도서관정보학회지 Vol.23 No.-
The purpose of this paper is to analyse the current status of reference education and to suggest directions for reference education in America and in Korea. For this purpose, the historical developments of reference services, and the names, problems and changes of reference courses are studied. The findings of the study can be summarized as follows; 1. The names of reference courses are various. In America, On-Line Services or Information Services are used in general, but in Korea, Reference Services are widely used. 2. In America, some library schools have only subject literature courses including business, law, music, etc. instead of basic reference courses. 3. Only one reference course is given by most schools in America and in Korea. However, a few schools which have no graduate courses provide two reference courses in Korea. 4. Analysis of textbooks used in reference courses shows that Reference Research by Joon-Shik Park, Reference Services and Reference Sources by Ock-Soon Noh are used in general. In addition, Introduction to Reference Work by Katz is used. 5. Lecture methods are generally used in teaching reference courses, but reviews of reference materials in library, class presentation, and case study method are also used. It is desirable that role playing and pathfinders' used in U.S. are introduced to our schools. 6. Analysis of library user instruction courses in Korea shows that 7 of 11 universities have the courses,, only one university teaches library user instruction as a part of reference courses, 3 universities don't. 7. Analysis of opinions about the directions for reference education shows that changes of reference courses names, expansion of courses contents, emphasis on communication technique, changes of teaching methods, proper combination of theory vs. practice, an increase in electronic reference education and training of subject specialist are needed.

This study was performed to investigate the asbestos contents on bulk samples of 4 building types(public, commercial, residential, school) in chungbuk area and collected from june 3, 2010 to July 10, 2011. We classified the bulk samples into the regulated asbestos containing building materials(ACBM) and architecture materials by 4 building types at removal and disposal sites. The results were as follows. The detection rate of the ACBMs were found mainly public(86.6%), and residential (82.1%) buildings. The founded asbestos were chrysotile and amosite. Compared with 4 building types, the contents of chrysotile in public, commercial, residential and school were 32.6% (3-70%), 43.9% (5-87%), 39.6(5-72%) and 46.7%(range 4-89%), respectively. The miscellaneous materials were found chrysotile and a mixed form with chrysotile and amosite for 4 building types. In the architecture materials, the contents of chrysotile was found mainly in slate (11.4%, range 2-37%). The slate in residential had high asbestos content of chrysotile (15.9%, range 1-31%). The textiles which collected from 4 building types were found chrysotile, the mixed form. The contents of chrysotile in cement flat board in public, commercial, residential and school were 8.9% (2-24%), 7.1% (1-16%), 7.9%(1-29%) and 3.7%(1-9%), respectively. In conclusion, this study is suggested that it should be contributed to manage the ACBM in 4 building types and to protect the health of workers at building removal sites.

조선업 용접공의 용접흄 생애누적노출량을 이용한 환기기능 평가
정춘화,임현우,구정완,박정일 大韓産業醫學會 2002 대한직업환경의학회지 Vol.14 No.4
목적 : 조선업 용접공들의 용접흄 생애 누적노출량을 이용하여 그들의 환기기능을 평가하기 위하여 본연구를 실시하였다. 방법 : 1개 대규모 조선소에서 용접흠에 5년이상 노출된 남자근로자 241명과 대조군으로 사무직 남자 근로자 80명을 대상으로 개인별 생애 누적노출량을 산출하였고 환기기능으로서 노력성폐활량(FVC), 1초량(FEV_1), 1초율(FEV_1%), 최대중간호기 속도(MMF), 최고호기기류속도(PEER)와 호기 FVC의 50%, 75% 시점에서의 최대호기기류인 FEF_50, FEF_75를 얻고저 노력성 호기곡선과 최대호기기류-용량곡선을 측정하여 분석한 결과는 다음과 같았다. 결과 : FEF_50과 FEF_75의 예측치에 대한 백분율(%pred)의 평균은 노출군이 대조군보다 유의하게 감소하였고 MMF는 감소하는 경향을 보였다. 현재의 노출수준 증가에 따라 감소하는 유의한 환기지수는 없었다. 환기지수 중 MMF, FEF_50 및 FEF_75는 노출 기간이 길수록 유의하게 감소하였다. 노출수준×노출기간으로 산출한 용접흄 누적노출량(C1)이 증가함에 따라 최대노출군에서 유의하게 감소한 환기지수는 FEF_75 뿐이었다. 노출수준, 노출기간, 환기시설, 생산량, 보호구사용, 용접봉 및 와이어 종류 등의 변수들을 고려하여 산출한 용접흠 누적 노출량(C2)이 증가함에 따라 최대노출군에서 유의하게 감소한 환기지수는 FEF_75이었으며 MMF 및 FEF_50은 감소하는 경향을 보였다. 또한 환기지수중 MMF, FEF_50 및 FEF_75의 경우 생애 누적노출량(C2)이 증가함에 따라 비정상적인 환기기능을 보인 근로자 비율이 유의하게 증가하였다. 결론 : 본 연구결과는 노출 관련 요인들을 고려하여 산출한 생애 누적노출량(C2)을 이용하여 용접흠에 노출된 근로자들의 환기기능을 평가하는데 있어서 MMF, FEF_50 및 FEF_75가 유용한 지수이었다. Objectives : This study was conducted to evaluate the ventilatory function in shipyard welders using the lifetime cumulative exposure to welding fumes. Methods : Ventilatory function tests were performed on 241 male welders at one large shipuad. exposed to welding fumes for over five years, and was compared to 80 male control subjects. Ventilatory function indices, such as forced vital capacity(FVC). one-second forced expiratory volume(FEV), rato of FEV_1 to FVC(FEV_1%), maximal mid-expira-tory flow(MMF). peak expiratory flow rate(PEER) and maximal expiratory flow at 50 and 75% of expited FVC(FEF_50 and FEF_75), were obtained by analuyzing forced expiratory spirograms and maximal expiratory flowvolume curves that were simultaneously mea-sured by an Impulse ocillometry(IOS) program in the standing position. Results : FEF_50 and FEF_75 expressed as a percentage of the predicted values were significatly lower in the exposure group than in the controls, and the MMF tended to decrease. The mens of all the ventilatory indices, expressed as percentage of the predicted values, were not significantly increased at the current exposure levels. The MMF, FEF_+50 and FEF_75, expressed as a percentage of the predicted values, were significantly decreased with an increase in exposure duration. Onlu the FEF_75, expressed as a percentage of the predicted value, was significantly decreased with an increase in the cunulative exposure to welding fumes(C1). The FEF_75, expressed as a percentage of the predicted value, was significantly decreased with an increase in the cumulative exposure to welding fumes(C2), The above parameters were calculated to consider the durrent exposure level, exposure duration, application of the ventilator sustem, production rate, personal protection device, electrode and swelding wire. The MMF and FDF_50, expressed as a percentage of the predicted value, tended to decrease, The proportion of workers with abnormal MMF, FDF_50 and FDF_75 were significantly increased with an increase in the cumulative exposure to welding fumes(C2). Conclusions : These findings suggested that the MMF, FDF_50 and FDF_75 are sensitive and practical indices for the evaluation of the ventilatory function of workeers exposed to welding fumes, when the lifetime cumulative exposure(C2) is considered as a factor affedting exposure.

The purpose of the present study is to analyze leadership of the public library organization in Korea using Fiedler's Contingency Theory. The study is only to analyze leader-member relations, task structure, position power of the public library organization in Korea by questionnaire method. After follow-up mailing, of the 143 responses received from librarians in 16 public libraries of Pusan and Kyung Sang Nam Do, 111 responses are analyzed. The results are summarized as follows: 1. Leader-member relations of public library organization in Korea are good. 2. The task of public library organization in Korea is unstructured. 3. The position power of public library organization in Korea is strong. In the light of this situation, relationship-oriented leaders will be more effective than task-oriented leaders in the Korean public library organization.
