류공식,최상구,이화우 群山大學校基礎科學硏究所 1993 基礎科學硏究 Vol.8 No.-

에폭시 수지의 경화제와 경화조건을 변화시켜가며 유리섬유/에폭시 적층판의 충격특성을 연구하였다. 상온경화에서는 분자사슬이 긴 폴리아미드(G-1034)를 경화제로 사용했을 때 가장 큰 충격강도를 나타내었다. 가열경화에서는 파괴개시에너지가 상온경화에 비하여 높게 나타났으며, 후경화에서는 파괴 전파에너지가 높게 나타났다. 저온시험에서는 모재로부터 섬유의 이탈이 많이 일어난 것이 높은 충격 강도를 나타내었다. The influence of hardener and curing condition were studied on the impact properties of epoxy resin laminated with glass- fiber experimentally. Generally, the initiation energy of the epoxy composites was increased with heat - cure, and the propagation energy was also increased with post-cure. The total impact strength of composites cured with hardener of polyamide type was than that of aliphatic or aromatic amine type. The impact strength was increased with enhancement of propagation energy when it was tested at low temperature.

This study was conducted by collecting and analyzing curricula of 19 colleges that has the department of dental laboratory technology throughout the country and analyzed by use of a questionnaire designed by the researcher with regard to details of actual operation in each college. Credit points for clinical training that has been conducted based on curricula vary from 3 to 20 points depending on colleges. But around 10 credit points are considered as ideal. For evaluation, the evaluation table was not applied but used as reference only. As criteria for evaluation such as evaluators, evaluation items and criteria for point distribution do not provide objectivity or reliability, development of accurate evaluation tools is required. It dis necessary for the bodies of colleges to maintain a level of mutual trust by visiting the sites of practical training regularly for the formation of progressive industry-academia cooperative relationships. When selecting the sites of practical training, it would be desirable to look for sites with better conditions for practical training in conjunction with related institutions. Besides, regarding clinical training education, in order for students to adapt themselves correctly to work environments and rapidly cultivate practical capabilities at site, systematic and efficient operation of training sites is required.

Lead poisoning is still prevalent and one of important occupational disease in Korea. To prevent undue high lead burden and maintain good health condition of lead workers in lead using industries, periodic health examination and regular biological monitoring of lead workers are often required in addition to the fundamental improvement of their working condition. To evaluate the effect of comprehensive occupational health program with regular biological monitoring on the level of lead exposure of lead workers in lead using industries, 11 year database from 1983 to 1994 of one storage battery factory was reviewed. From 1983 to end of 1986 only periodic health examination was provided to the lead workers, but from 1987 comprehensive occupational health program with regular biological monitoring was provided to maintain better health condition of lead workers. Selected study variables for lead exposure were blood lead(PbB), zinc protoporphyrin in blood(ZPP), δ-aminolevulinic acid in urine(ALAU), hemoglobin(Hb), hematocrit(HCT). Information on sex, age and work duration was also reviewed. 5 years data from 1983 to 1987 and 3 years data from 1990, 1993 and 1994 were available for all lead exposure indices except ALAU which has only 5 years data from 1983 to 1997. The results of 11 years longitudinal observation of lead indices are all follows: 1. The mean value of ZPP of lead workers in 1983 was 148.7±73.1 ㎍/㎗(Male: 145.5±72.3, Female: 168.1±79.1), whereas that of ZPP of lead workers in 1994 was decreased to 64.3±32.7 ㎍/㎗(Male: 60.2±28.8, Female: 95.2±43.4). 2. The mean value of PbB of lead workers in 1983 was 56.4±18.8 ㎍/㎗(Male: 55.59±19.1, Female: 59.6±19.1), whereas that of PbB of lead workers in 1994 was dcreased to 35.4±11.9 ㎍/㎗(Male: 35.7±12.0, Female: 32.8±10.8). 3. The mean value of Hb of lead workers in 1983 was 14.1±1.4 g/㎗(Male: 14.4±1.1, Female: 11.7±0.8), whereas that of Hb of lead workers in 1994 was increased to 15.6±1.5 g/㎗(Male: 15.9±1.2, Female: 12.9±1.1). 4. Blood lead is most highly correlated with ZPP(r=0.522, male:0.54 and female:0.50) and also correlated with ALAU and work duration also. 5. The simple regression analysis of PbB and ZPP showed different coefficient of regression by the measurement year, but there was no difference of coefficient of regression between sex. The slope of equation of pooled data for 1983-1986 without comprehensive occupational health program was 2.16 and differed from that of pooled data for 1987-1994(1.25). This difference suggests that the unit effect of blood lead on ZPP was relatively smaller in later period of comprehensive occupational health program than carly period without comprehensive program. The slope change in the analysis of linear regression of PbB on ZPP in lead workers can be used to evaluate the possible effect of health intervention to prevent undue high lead absorption in lead using industries. 6. 11 years occupational health service in this storage battery factory brought out considerable improvement of health status of lead workers in terms of decrease of PbB and ZPP and increase of Hb and the improvement was more remarkable after the introduction of comprehensive occupational health program.

A survey on school nurses presently engaged in school health services in Korea was conducted in December 1969 for the period of one month, to find out activities, line of supervision, general and special preparation for the job, preferances for geographical location and level of school, and a composite picture of school nurses. Study population was 765 nurses presently engaged in school nursing and method used for data collection was a questionnaire consisting of 65 items which were distributed and replies obtained by mail. 63 per cent of the study population responded and returned the questionnaires. An analysis of the data collected showed the following findings. 1. General composition of school nurses: majority of nurses were in the age group of 25-29 and married nurses appeared to have a preference in school nursing. Basic nursing training of the nurses showed that the technical nursing school graduates occupied posts at primary schools and collegiate program graduates and diploma graduates held posts at middle and high schools. The experiences of nurses revealed that more nurses with long nursing experience were engaged at the lower level of schools. This may be revealing the history of school nursing services at the different level of schools. 2. Special training in school nursing: 60 per cent of total respondents have had short or long term training to perepare themselves for the job. Large proportion of older nurses had some form of special training in public health. For the preparation of school nursing in basic nursing education, the graduates of lower level of school appeared to have less learning experience. 3. Area preference of respondents: majority of diploma graduates and all collegiate graduates are engaged in urban schools while majority of technical graduates and a small proportion of diploma graduates hold positions in rural schools. 4. Common number of classes in a rural school ranged from 30 to 49 while urban schools showed a wider range of 40 to 79 classes in a school. However, the work of a school nurse in general was shown to be overloaded regardless of characteristics of community. 5. Common walking distance from school to nearest health facilities was found to be 15 minutes in both communities. Nearest health facilities in both communities was private clnics, and health center heald in second nearest place in rural community. 6. School nurse's line of professional supervision was none existance except administrative one. 7. As for the school nurses activites, functions of. management and teaching, direct health services, case finding and follow-up care, class teaching participation of health related subjects were included. The proportion of class teaching and health counselling in daily activites was about 10 per cent while larger proportion of time was allocated for teaching of non-health subjects as substitutes of regular teaching when professional teachers were absent due to some reason. With the consideration of the above mentioned factors related to school nurses activities, the following recommendations are made: 1. Standardized professional preparation of school nurses should be provided. 2. Multiple angle of administrative coordiantion and improvement of its mechanism should be brought about for better and proper utilization of school nurses through recognition of importance of school health services. 3. Active participation of school nurses to professional organization for personal as well as professional growth should be emphsized. 4. Provision of job descriptions, standards for qualification and practice must be made. 5. Opportunity for refresher courses should be givent to school nurses to inform up to date development in fields of public health and related areas.

The twin sisters case of folie simultanee is reported here in this paper. A case of folie simultanee is described as two or more people becoming psychotic simultaneously and sharing the same delusion. The results of psychodynamic approach for this case are as follows. 1. There are a variety of conflicting hypotheses on the orgin of the disorder, ranging from the etiological explanation of organic factor to various psychodynamic approach. In this case, there is no evidence of hereditary factor on the laboratory findings and family history. Therefore the authors stressed that the psychodynamic formulation of the disorder is on the importance .of the etiological rol. It seem significant to describe that the etiology is multidimensional and includes factors such as character structure formation in processing of object relations, the emotional relationship between the partners, socio-environmental conditions and hereditary predisposition. 2. There are two issues in folie simultanee. The one is related to diagnosis. It is consider to distinguish the inductor from the recipient. The other is subject to treatment. It is important to determine whether separate the inductor and recipient by admitting the inductor for a psychiatric center or not. Furthermore, the inductor and recipient's weak ego state should be recognized in planning various psychiatric treatments. 3. It could be found in the role reversal phenomenon between the inductor and recipient during long-term course.
