This study was conducted to investigate the relationship between an eating disorder, body image, depression and self-esteem amongst a subject group of 282 college women between Jan.,1st and 30th,2002, to provide base data for eating disorder levels of college women and to provide base data for health control. The evaluative instrument was a constructive questionnaire that consisted of 8 items of general characteristics and weight control questions, 24 questions relating to eating disorders, 17 questions pertaining to body image, 10 questions pertaining to depression and 10 questions pertaining to self-esteem. To identify the levels of an eating disorder, body image, depression and self-esteem perceived by subjects, the researcher used means and SDs. To test the significance of a subject's eating disorder, body image, depression and self-esteem according to the BMI, the researcher used the t-test. To test the correlation between the BMI, an eating disorder, body image, depression and self-esteem, the researcher used Pearson correlation coefficient. The results of this study are as follows. The mean score for anorexia nervosa was 31.52 and the mean score for bulimia nervosa was 24.12. Differences between the underweight group and the normal weight group in the level of eating disorders were significant (t=-6.94, p=.000). There were high positive correlations between the BMI and an eating disorder (r=.383, p<.01), between an eating disorder and depression (r=.161, p<.01), between body image and self-esteem (r=.653, p<.01). In addition, there were high negative correlations between an eating disorder and body image (r=-.214, p<01), between an eating disorder and self-esteem (r=-.196, p<.01), between depression and body image (r=-.541, p<.01), and between depression and self-esteem (r=-.537, p<.01). These results indicate that Korean college women need more education and counseling on dietary habits. Also, the systemic efforts reestablish the social standard of the beauty should be taken. Further empirical and experimental studies would be required for investigating for the factors influencing the eating attitude of the college women and discriminating the variables affecting the various specific dimensions of the eating attitude.

Purpose: Renal size is an important indicator to determine adequate organ growth in children. The aim of this study was to estimate renal size with Technesium-99m dimercaptosuccinic acid (DMSA) scan and propose a simple formula for predicting renal length in normal Korean children. Methods: This study included 346 children (148 boys and 198 girls; age range, 1 month to 17 years) in whom renal length was measured using the DMSA scan. Patients with anatomical renal abnormalities or acute pyelonephritis were excluded. Children were divided into two groups: 214 children (61.8%) were less than a year old (group 1) and 132 (38.2%) were ${\geq}1$ year (group 2). Results: Renal length was larger on the left side than the right side, and there was no significant gender-related difference in renal length. We propose the following formula for renal length based on the analysis of the 346 children in our study: the formula was as follows: $4.682{\times}age(month)^{0.137}$, $R^2=0.780$. In group 1, the formula was renal length $(cm)=0.127{\times}age(month)+5.144$, $R^2=0.354$, and in group 2, the formula was $0.334{\times}age(year)+6.477$, $R^2=0.829$. Conclusion: It is difficult to establish simple formulae in infants ($R^2=0.354$). Therefore, further studies including relevant variables are needed for this age group. We proposed formulae to estimate renal length in Korean children over 1 year of age by using the DMSA scan.

Pleurotus eryngii, known as king oyster mushroom has been widely used for nutritional and medicinal purposes. This study was initiated to screen the suitable conditions for mycelial growth and to determine the phylogenetic relationship of the selected strains. Optimal mycelial growth was observed at $30{^{\circ}C}$ and minimum mycelial growth observed at $10{^{\circ}C}$. This mushroom tolerates a broad pH range for mycelial growth, with most favorable growth observed at pH 6. Results also indicated that glucose peptone, yeast malt extract and mushroom complete media were favorable growth media, while Hennerberg and Hoppkins media were unfavorable. Dextrin was the best and xylose the least effective carbon sources. Results revealed that inorganic nitrogen sources were less effective than organic sources for the mycelial growth of P. eryngii. Investigation of genetic diversity is necessary to identify the strains. The ITS region of rDNA were amplified using PCR. The size of the ITS1 and ITS2 regions of rDNA from the different strains varied from 214 to 222 bp and 145 to 236 bp, respectively. The sequence of ITS2 was more variable than that of ITS1, and the 5.8S sequences were identical. A phylogenetic tree based on the ITS region sequences indicated that selected strains could be classified into six clusters. Fourteen IUM and ATCC- 90212 strains were also analyzed by RAPD with 20 arbitrary primers. Fourteen of these primers were efficiently amplified the genomic DNA. The number of amplified bands varied with the primers and strains, with polymorphic fragments in the range from 0.2 to 2.3 kb.

Purpose: This study was a descriptive research to investigate the health behavior, health status and self-efficacy according to the concepts of Sasangin. Method: Participants in this study were 214 nurses in hospitals in Seoul, Kyunggi and B city. Data were collected using interview with questionnaires from Oct.2 to Nov.30, 2003. The measurement tools were the QSCC II by Kim et al., Health Behavior by Kim, CMI by Nam and self-efficacy by Sherer, all of which have resported reliability. For the purpose of the study, the collected data were analyzed by Frequency, ANOVA, and Pearson correlation coefficients. Results: 1) There was a significant difference in health behavior according to constitution (F=1 273, p=.020). 2) There was a negative correlation between health behavior and health status for Taeumin (r=-.376, p=.002). There was also a negative correlation between health status and self-efficacy for Taeumin (r=-.271, p=.029). Conclusion: The results of this study showed that there were significant differences in health behavior, health status and self-efficacy for the participants according to the constitution of each nurse. So, based on these results, determining and fully understanding the client's constitution are important as these are the foundations of Eum-Yang and personal characteristics. Therefore, we have to consider the constitution when we provide nursing care. However, this study did not show a correlation between health behavior, health status and self efficacy for Soyangin and Soeumin. Further research is needed to determine if there is a relation between these variables according to various constitutions.

Scrub typhus and murine typhus are common endemic febrile illness in the fall in Korea. Scrub typhus is caused by Orientia tsutsugomushi, murine typhus is caused by Rickettsia typhi. Trombiculid mites are known as both the vector and the reservoir host of O tsutsugamushi, the mites which transmit O tsutsugomushi have been reported to be Leptotrombidium pallidum and L scutellare. The author carried out an epidemiological study of scrub typhus and murine typhus in Kyodong-Myeon, Kanghwa-Gun, Incheon in relation to the residents and the host rodents, such as their distribution, seroepidemiology, and population density of chigger mites. 1. Out of 900 residents, 33(3.7%) showed positive reaction to O tsutsugamushi, 24(2.7%) to R typhi. 2. In the seropositives to O tsutsugamushi or R typhi, between the sixties and the seventies of the age were dominant. 3. In the seropositives to O tsutsugamushi serotypically Gilliam was dominant. 4. Among the total 42 field rodents trapped by the sherman traps, 18 rodents were Apodemus agrarius(42.9%), 13 rodents were Crocidura lasiura(31.0%), 5 rodents were Musmusculus(11.9%), 2 rodents(4.8%) were Crocidura suaveolens, Rattus norvegicus, Tscherskia triton, respectively. 5. Out of 42 field rodents, 25 were parasitized by 4,419 chigger mites, showing 59.5% of the infestation rate and 98.8 of the chigger index. L pallidum parasitized in A agrarius, C lasiura, M musculus, R norvegicus and T triton, and L scutellare parasitized only C lasiura. 6. Antibodies in the sera of field rodents against O tsutsugamushi and R typhi were investigated by indirect immunofluorescent antibody technique. Positive rate of antibody against O tsutsugamushi were 11.9(5 of 42) and all of the positive is A agrarius. Antibody against R typhi was not detected. These results might provide the basic information for the management of scrub typhus and murine typhus in Kyodong-myeon, where the epidemiological studies on scrub typhus and murine typhus was not carried out enough.

내분비장애 추정물질의 분류를 위해 많은 시험법이 연구되고 있는데 추후 내분비장애 추정물질로 분류된 기등록 농약에 대한 자료요구 또는 신규 등록농약에 대한 등록기준의 추가 등을 고려하여 OECD와 EPA에서 권장하는 시험법을 확립하고자 본 연구를 수행하였다. 시험약제를 30일간 경구 투여하여 조사한 결과, alachlor 투여 수컷에서 25 mg/kg/day, 50 mg/kg/day에서 고환과 갑성선의 중량이 증가하였다. Alachlor 투여 암컷에서는 질의 중량이 25, 50 mg/kg/day에서 감소하였고 25 mg/kg/day에서 갑상선의 중량이 감소하였다. Alachlor 투여 암컷 25, 50 mg/kg/day에서 주요 갑상선 호르몬인 T4와 성호르몬 testosterone이 감소하였다. 따라서 pubertal assay 결과 alachlor는 갑상선 호르몬성 영향이 의심되었다. 시험세포를 이용한 시험 결과, 시험약제를 1 nM에서 1000 nM까지 처리하였을 때 음성대조군과 비교하여 alachlor는 100-134%의 갑상선 호르몬성 영향을 나타내었다. 따라서 세포를 이용한 시험에서는 alachlor에 의한 갑상선 호르몬성 영향이 나타나는 것으로 판단되었다. 항갑상선 호르몬성 영향 시험에서는 시험약제 100 nM과 T4의 혼합 처리시 alachlor는 항갑상선 호르몬성 영향은 나타나지 않았다.
