The purpose of this study is to investigate children's preceptions of sexual abuse and to suggest the basic data for the development of sexual abuse prevention program. The sampling subjects for this study were 121 students of 3rd grade in elementary school and 105 children of 7 years old in kindergarten. Statistical analysis were performed using the Statistical Analysis System(SAS). The obtained date were analyses by frequency, percentage and chi-squre test. The major finding were that (1) Most children perceived that different types of sexual abuse and they had an idea to reject them. (2) Children's perception about sexcual abuser and sexual abused were various. The perceived that sexual abused would be mostly girls and young children and sexual abuser would be mostly boys in middle school or hight school student. (3) Most children firmly perceived the risks in 8 supposed situation based on the previous study. Risk perception of sexual abuse is a little bit different by children's gender and age. (4) Most children answered sexual abuses might happen to themselves, because they were young and helpless. In that case, they would be very unhappy. It showed that they had a very unrealistic, passive perveption about prevention of sexual abuse.

Toluene diisocyanate(TDI) is widely used in the production of flexible polyurethane foams, as well as in the formulation of polyurethane paints and coatings. The commercial material is generally a mixture of 2,4- and 2, 6-TDI, the predominant mix being 80% 2,4 and 20% 2,6-TDI. The 2,4-isomer is considerably more reactive than the 2,6-TDI at ambient temperatures due to steric factors involving the positions of the isocyanate groups relative to the ring methyl group. Because of this difference in the reactivities of the isomers, it seemed probable that there might be an increase in the amount of 2,6-TDI offgased relative to the 2,4-isomer. Therefore a relative enrichment of the 2,6-TDI has been found in industrial atmospheres. Toluene diamines, which are metabolites of TDI, in urine have a linear relation with exposure to TDI, so that urianry TDA could be used as a biological index of the exposure to TDI. This study was conducted to investigate the distribution of TDI isomer in industrial atmospheres and to propose proper biological monitoring methods by identifying the relationships between the environmental TDI exposure and concentration of TDA in urine. Concentrations of 2, 4-TDI and 2, 6-TDI in air were 4.38㎍/㎥ and 25.43㎍/㎥, respectively. The Threshold Limited Value of 40㎍/㎥ was exceeded for the 2, 6-TDI in about 46.8%(22 samples) of the samples, while the 2, 4-TDI was not at all exceeded. The ratio between 2, 4-TDI and 2, 6-TDI varied in air samples in the range of 2.4%:97.6%-51.0%:49.0%. There was an enrichment of 2, 6-TDI in air relative to the 2, 4-TDI. Concentrations of 2, 4-TDA and 2, 6-TDA in urine were 1.31㎍/g creatinine and 4.16㎍/g creatinine, respectively. The ratio between 2, 4-TDA and 2, 6-TDA varied in urine samples in the range of 1.4%:98.6%-99.9%:0.1%. There was an enrichment of 2, 6-TDA in urine relative to the 2, 4-TDA. No relation between the concerations of TDA isomer in urine and concerations of TDI isomer in air was found. Above results of this study, workers were more exposed to the 2, 6-TDI relative to the 2, 4-TDI in industrial atmospheres. Therefore, the establishment of TLV for 2, 6-TDI should be considered. Also, the further studies on biological monitorigs of workers exposed to TDI should be continued.

This paper deals with a mathematical model and an algorithm for the problem of determining k most vital arcs in the shortest path problem. First, we propose a 0-1 integer programming model for finding k most vital arcs in shortest path problem given the ordered set of paths with cardinality q. Next, we also propose an algorithm for finding k most vital arcs in the shortest path problem which uses the 0-1 integer programming model and shortest path algorithm and maximum flow algorithms repeatedly. Malik et al. proposed a non-polynomial algorithm to solve the problem, but their algorithm was contradicted by Bar-Noy et al. with a counter example to the algorithm in 1995. But using our algorithm. the exact solution can be found differently from the algorithm of Malik et al.

무용 활동을 통한 자아 신체능력 평가와 자아존중 정도에 관한 연구

안재연 한국유아체육학회 2003 한국유아체육학회지 Vol.4 No.-

본 연구는 Sonstroem(1978:1984)의 가설적 모형과 실험적 선행 연구 그리고, 체육 연구소 집에 발표된 정청희·허정식·성창훈(1993)의 실험논문에 근거를 두고 초등학교 4, 5, 6학년 여학생을 대상으로 지속적인 무용교육이 자기 신체평가와 자기 존중심에 긍정적인 영향을 미치는지를 검증하여 무용의 교육적 중요성을 확인하려 하였다. 이를 위하여 본 연구에서는 무용 교육 무경험 집단 100명과 무용교육 유 경험집단 111명 중에서 A(무용교육 6개월~l년 미만) 45명, B(무용교육 1년 이상~5년 미만) 32명, C(무용교육 5년 이상~) 34명 총 211명을 대상으로 Sonstroem이 제작한 자기 실체평가 척도 간편형 (1974)과 Rosenberg가 제작한 자기존중심 척도 간편형(1965)에 대한 반응을 연구문제별로 비교, 분석했다. 결론적으로 지속적인 무용 활동은 자아신체능력과 자아존중에 긍정적인 영향을 미쳤으며 무용 활동 경험기간이 길수록 더 긍정적인 영향을 미쳤다. 이러한 관점에서 볼 때, 지속적인 무용 활동은 일반적인 아동 뿐 만 아니라 높은 자아존중과 자신감이 요구되어지는 아동들에게 유익한 프로그램인 것이 검증되었다. This study is based on Sonstroem(1978:1984)'s model and experimental studies, and experimental theses of Jung Chung-hee, Huh Jung-sik and Sung Chang-jun(1993) published in a small collection of studies on P.E. (Physical Education). The purpose of this study is to inspect if continuous dance education exerts a positive influence on self-perception and self-concept, and if there is a correlation between by comparing the difference of self-perception and self-concept between girl students who experienced continuous dance education and the others who didn't among some 4th, 5th and 6th graders of elementary school. Among various psychological variables, self-respect is an important variable which is related to physical exercise, and a lot of studies including Sonstroem(1984)'s show that continuous physical exercise makes a clear improvement of self-respect, and they suggest the degree of change is remarkable. Although these results are not directly related to dance, but it implies a lot in that dance is in the same category of physical exercise. To identify the purpose of this study, the researcher selected a group of 101 elementary school girls who do not have any experience of dance education and the other groups of experienced students (A 46, B 32, C 33)- total 212 students. The researcher made a comparison between the two groups using Sonstroem's simplified scale of perceiving one's body(1974), and Rosenberg's simplified scale of self-concept(1965). The test paper was filled by self-evaluation, and the data was analyzed by sub program of SPSS PC+, ccrrelation analysis and dispersed analysis. The results of the statistical analysis are summarized as follows. First, there is meaningful difference between self-concept of the two groups(p<.001), and there is also meaningful difference among the groups with experience of dance education in their concept of their body (p<.001) in the aspect strong body, cooperating power, sense of exercise, function, leadership, self-confidence, talent, timing, competence, muscular strength and competence except strength. Second, there is meaningful difference between self-perception of the two groups (p<.001), and there is also meaningful difference among the groups with experience of dance education(p<.001) in the aspect of satisfaction, quality, strong points, competence, pride, value, success and attitude except existence and self-pride. Third, there is meaningful difference in self-perception according to the experiencing period of continuous dance activity (p<.05). The group of more than 5 years' experience has the highest average score followed by the group of more than a year but less than 5 years' experience, and the group of more than six months but less than a year's experience has the lowest score. Looking at the difference in sub areas of self-perception according to the experience of dance activity, there is meaningful difference in strong body, cooperating power, sense of exercise, muscular strength and competence except function, strength, talent and timing. Fourth, looking at differnce in self-concept according to the experiencing period of dance activity through post-inspection, the group of more than 5 years' experience has the highest score followed by the group of more than 6 months but less than 1 year's experience, and the group of more than 1 year's but less than 5 years' experience has the lowest score. There is no meaningful difference between the group of more than 6 months but less than 1 year's experience and the one of more than 1 year's but less than 5 years'experience. Looking at difference between sub areas of self-concept according to the experiencing period of dance activity, there is meaningful difference between the group of more 5 years' experience and that of less than five years' experience, and the group of more 5 years' experience has higher score in the aspect of quality, strong points, pride and value except satisfaction competence, existence, success and attitude. Fifth, as the result of analysing correlation between self-perception and self-concept, correlation variable is r=.530, which shows direct correlation(+)(p<.01). In each sub area of self-perception, all show positive (+) correlation with self-perception or self-concept except in strength, competence, and self-pride. Also, as the result of analysing correlation between self-perception and self-concept of each group, the correlation variable is r=.502 in case of having dance experience, and there is no ccrrelation at p<.05 in case of no dance experience. In case of having dance experience of 6 months to 1 year, the correlation variable is r=.319(p<.05), .451(p<.01) in case of more than 1 year but less than 5 years, and .841(p<.01) in case of more than 5 years' experience. In conclusion, lasting dance experience positively influences self-perception and self-concept, and it will become a useful program for general children, children with bad relationship with their parents and some other children who should have high self-concept than others. Also, recognizing the wide influence of self-concept on individual life, we should develop variety of dance education programs for each subject and period of experience that will positively influence their self-perception and self-concept.

The purpose of this study is to investigate the consumers' cognition and buying behavior on sports brand character. Since the character industries are booming, this study focused on the source and the expression method of sports brand characters that are already known to consumers. Subjects of this study were university students who were interested in sports brand characters, living in Seoul and Kyenggi-do. The questionnaire were developed based on the previous studies. Data were analyzed by Frequency analysis, ANOVA, Duncan Test, and Spearman's Rho. The results were as follows: 1. The most preferred source of sports brands character was "illustrated human figure"(i.e. a famous athlete like Michael Jordan). And the most favorite expression method of character was the combination of letter and symbol as the character of ASICS and NIKE, 2. The important design factors of sports brand character were the symbolism and aesthetics. The consumer recognized NIKE as the most well-designed character design. 3. Consumers' preference of sports brand was found to be NIKE, REEBOK, ADIDAS, and FILA, in order. The reasons for preference were the design, the brand image, and the quality. On the other hand, the most frequently purchased brand was NIKE, FILA, and ADIDAS in order. Most of the purchase took place in the brand outlet store, and the consumers usually came with their friends for purchase of sports brand. The display of store was the consumers' major source of information. 4. The preference group of sports brand character recognized more importantly color, design, brand, and especially fashionability than the non-preference group. And the most important criteria for brand selection were design, price, and comfort orderly. 5. Female consumers recognized more importantly color, design, brand, and others' recommendations that male consumers. The aged consumers recognized importantly durability, comfort, and quality.

This study was conducted to find out the characteristics, type of the duty and job satisfaction of health care managers at the worksite. The subjects of this study were 306 health care managers serving at worksite situated in Kyungin presently in 1994, concerning their job. Major dependent variables were health management, environmental management, and health planning related with health care managers job; these variables were measured by nominal scale consisted of 9 items respectively. The collected data were analysed and some major results are as follows: 1. It appeared that according to the qualification of health care managers, nurses showed high performing rate in duty of health management and health planning, industrial hygienist showed high performing rate relating to working environment managemant, and regarding their holding an additional post, the number of environmental managers held more an additionnal post than other qualified managers, thereby showing significant relatively, and however, no relation with qualification was there in decision-making. 2. The performing rate relating to health management was significantly correlate with female, youth, unmarried, higher education, general affairs in post of duty, general employee in position, only duty of health, low monthly income and nurse. But, the performing rate relating to environmental management was significantly correlate with manufacturing industries, industrial health and safety committee, male, old age, married, long work duration, additional post, high monthly income, and hygienist and environmental managers. The performing rate relating to health and environmental management, but the performing rate relating to health management was not significantly correlate with the performing rate relating to environmental management. 3. In multiple regression analysis, common major determinants of the performing duty relating to health management, environmental management and health planning were industrial health and safety committee, type of industry, education, and qualification of industry's health care managers. Additionally, age was selected as highly correlated with the performing duty relating to environmental management, and work duration and post of duty of health care managers in industry were selected as highly correlated with the performing duty relating to health planning. Based on the results indicated above, it could be understood that characteristics of the worksite - industrial health and safety committee, scale and types of industry, and characteristics of health care managers - age, education, post of duty, work duration and qualification had relations with their type of the duty. Therefore, it is required that the reference to the above-showing results such as guiding for them to precisely grasp their performing duty according to their qualification, heightening their participation in decision-making, extending the industrial health service, etc., operation and management of health care managers at the worksite should be made into being more efficient.

Nitric Oxide (NO), derived from L-arginine, is produced by two types (constitutive and inducible) of nitric oxide synthase (NOS: cNOS and iNOS). The NO produced in large amounts by the iNOS is known to be responsible for the vasodilation and hypotension observed in septic shock and inflammation. The inhibitors of iNOS, thus, may be useful candidate for the treatment of inflammatory diseases accompanied by the overproduction of NO. We prepared alcoholic extracts of herbal drugs which have been used for the treatment of inflammation in oriental medicine. We have screened the inhibitory activity of NO production in lipopolysaccharide (LPS)-activated macrophages after the treatment of these extracts. Among the 81 kinds of extracts of herbal drugs, 34 extracts showed potent inhibitory activity of NO production above 50% at the concentration of 50 (μg/ml. The inhibitory activities of NO production were also evaluated for several solvent fractions at three different concentrations. Especially, hexane soluble fractions of Agrimonia pilosa, Hydrangea serrata, Machilus thunbergii, Prunella vulgaris, Saussurea lappa, Tussilago farfara, and ethyl acetate soluble fractions of Angelica gigas, Ostericum koreanum, Torilis japonica, Perilla frutescence showed moderate activity at 10 and/ or 25 (μg/ml. These fractions are promising candidates for the study of the activity-guided chromatographic purification of active compounds.

To evaluate the differences of benzidine exposure patterns of the workers in two benzidine-based dye manufacturing factories, the concentration of benzidine in air, blood and urine were measured. The air levels of benzidine dihydrochloride and benzidine-based dye were measured by high performance liquid chromatography with ultraviolet detector. Blood samples were collected at 3 hours after exposure and urine samples were collected at the end of shift. Blood and urine samples were analyzed by high performance liquid chromatography with electrochemical detector. The level of benzidine in reaction process (input, diazotization, and coupling) was 0.381±7950g/㎥. The blood benzidine was deteced in 25 workers among 38 in reaction process and their mean levels were 0.0153±.0376 ng/mg Hb. The urinary benzidine was detected for 11 workers among 38 workers in the reaction process. The level of benzidine-based dye in drying and packing process was 52.1748±14.4111g/㎥. The blood benzidine was deteced in 6 workers among 38 in drying and packing process and their mean levels was 0.0062±.0274 ng/mg Hb. The urinary benzidine was detected for 1 worker among 38 workers exposed to benzidine-based dye. The blood and urinary benzidine were detected in workers exposed to benzidine-based dye. Such results suggested that some part of benzidine-based dye was metaboized to benzidine. Therefore, some regulations for manufacturing and use of the benzidine-based dye are needed to prevent its hazards in industries.
