Purpose: The study aimed to identify factors affecting unintentional injuries at school focusing on violent experiences in adolescents. Methods: The study used the raw data of the Korea Youth Risk Behavior Web-based Survey (2019). A total of 60,040 students were included in the analysis. Descriptive statistics, χ2 test, and multiple logistic regression were performed, using SPSS version 25.0. General characteristics, gender, school, academic achievement, living with family, socioeconomic status, vigorous physical activity, perceived stress, sleep satisfaction, high caffeine drinking, risky alcohol drinking, smoking, sexual experience, drug use, and safety education, were adjusted for and the relationship between unintentional injuries and violence was analyzed. Results: The results showed 2.4% of the adolescents had experienced violence and 24.7% had suffered unintentional injuries. Violent experiences had a significant effect on unintentional injuries among adolescents. Injuries were 1.93 times higher among adolescents who had experienced violence. Gender, school levels, high-intensity physical activity, stress, sleep satisfaction, high caffeine drinks, dangerous drinking, drug use, and safety education were associated with unintentional injuries among adolescents. Conclusion: Adolescents at high risk of suffering violence and injuries should be identified and assessed preemptively. In addition, it is necessary to implement systematic school health-centered safety education programs in order to prevent violence and injuries.

The aim of this study is to describe degree of fatigue and factors related to fatigue in patients with rheumatoid arthritis. The subjects of the study consist of one hundred fifty-eight outpatients with rheumatoid arthritis at three university hospitals in Taegu between July 10 and August 30, 1999. The instrument used in this study was the Multidimensional Assessment of Fatigue developed by Belza et al.(1995) and revised by Jung, Bok Hee. Kim, Myung Ae(1998). Analysis of data was done by using the descriptive statistics, t-test, ANOVA and Duncan with SPSS program. The major findings can be summarized as follows: 1. Degree of fatigue in patient with Rheumatoid Arthritis was shown the average 22.91 out of the total scores 40. Four subscales of fatigue scores are common fatigue degree 6.37, fatigue timing at the last week 5.92, distress due to fatigue 5.40 and degree of daily activity fatigue 5.22. Among the realms of daily activity fatigue, outdoor activity(6.00), sexual life(5.84), doing the household(5.66), shopping(5.61), other exercise except stroll(5.54) were shown the high degree of fatigue and cooking(4.97), a stroll(4.48), recreation(4.35) showed the low degree of fatigue. 2. There were no significant differences on the total degree of fatigue according to demographic variables. But there were some significant differences on the subscale fatigue scores according to demographic variables. Degree of daily activity fatigue according to sex was shown significant difference (t=-2.358, p=.020), and according to education level was shown significant difference(F=3.938, p=.005) and common fatigue degree according to age was shown significant difference(F=2.853, p=.026). Conclusively fatigue is one of difficult problems for patients with rheumatoid arthritis. Therefore it is necessary to develop some nursing intervention for reducing fatigue of rheumatoid arthritis patients.

This experiment was carried out to develop a new technique of identifying XX of XY-bearing bisected embryos prior to implantation by immunological method. H-Y antiserum prepared in inbred Wastar female rats by repeated immunization with spleen cells from males of the same strain. The reactivity of H-Y antibody was confirmed by culturing mouse embryos in the medium containing H-Y antiserum and complement obtained from the guinea pig. The optimal condition for the activity of H-Y antibody was also investigated by culturing embryos under the concentraton or affected H-Y antibody was also investigated by culturing embryos under the concentration or affected H-Y antibody and culture rate. However, production of live young or sex rates of male and female from embryos transferred with psudopregnant. The biological test with the morula stage embryos showed that H-Y antibody was formed in all female rats immunized with spleen cell, but it was formed only in 80% female rats immunized with the antigen. When the bisected mouse embryos were cultured in vitro for 5~6 hours in morula stage, of 457 bisected embryos 81.4% of then were developed to the blastocyst stage. When the concentration rate of complement to H-Y antiserum varied from 1.0~5.0${mu}ell$, the lysis-rate of embryo was 19.5 to 67.3%. The concentration rate of complement did not influence the lysis-rate of embryos(P<0.05). The morphology embryos of bisected, zona-free and intact embryos showed the embryos lysis rate of 58.6, 42.7 and 48.5% respectively(P<0.05). Pregnancy rate were 50.0, 45.5 and 57.1% in psudopregnant recipient transferred with bisected, zona-free and intact blastocyst embryos. However, production of live youngs, sexual rate of male or female was 24(50.0:50.0), 22(45.5:55.5) and 36(58.3:41.7)mice, but affected and non affected half embryos with H-Y antiserum treatment was 23.1 and 26.7%. Also production of live youngs and sexual rate was 14(92.9:7.1) and 17(17.6:82.4)mice in affected and non affected half embryos in H-Y antiserum treatment(P<0.05).

Ginseng has been used in maintaining physical vitality throughout the far-eastern countries and recently its metabolism and actions on neurologic, cardiovascular, and endocrinologic systems are studied. Korean red ginseng (KRG) has been used in various ailments, and to prove its efficacy for erectile dysfunction an international study on Asians other than Korean was performed. Patients with borderline organic and psychogenic erectile dysfunction were included. KRG were given daily, and placebo were given as controls. Treatment lasted a total of 3 months. Surveys including libido, erection, ejaculation, sexual activity, and sexual satisfaction were given. Serum testosterone and erectile function study were taken. Among the 64 patients, 37 patients were followed with KRG. Five had diabetes, 5 hypertension, 5 hypercholesterolemia, 6 low testosterone, 6 psychogenic, and 11 idiopathic. The improvement after KRG administration was $70.2\%$ on objective questionnaire and $75.7\%$ on subjective analysis. When KRG were given, all parameters surveyed have shown improvements compared to the placebo. The effects of KRG in Chinese and Singapores were similar to the Koreans. Serum testosterone levels were nonnalized in 6 patients with KRG, who's serum testosterone levels were reduced from pre-study. Two patient reported constipation, and 2 gastric upsets in the KRG group. In conclusion, KRG has beneficiary action on male erectile capabilities with little side effects. KRG is effective in Koreans and also Asians. The exact action mechanism and the active ingredients in KRG need to be studied.

솔껍질깍지벌레 성충의 탈피(우화 : eclosin) 및 우화후의 탈출 (emergence)습성이 실내조건에서 조사되었다. 수컷성충의 탈피는 일종 특정한 시간에 국한되지 않으며 갓 탈히한 성충은 실온에서 정지성충(pre-emergence adult)으로 0.5~2.5일 경화후 고치로부터 탈출하였다. 대부분의 수컷성충은 일조후 1시간 이내에 탈출하였으며 이러한 탈출현상은 광도가 높은 경우 더욱 빨리 진행되었다. 암텃성충은 우화후 곧 탈피장소에서 이동하며 대부분 일조후 3시간이내에 우화하였다. 수컷이 우화후 고치속에 일정기간 정치하여 있는 것은 갓 우화한 성충의 생리적 성숙을 돕고 또한 번식활동을 일중 특정한 시간에 하기 위한 것으로 풀이된다.
