  • Statistical differences between men and women are investigated for a total of eleven joint motions during level walking. Human locomotion which exhibits nonlinear dynamical behaviors is quantified by the chaos analysis. Time series of joint motions was obtained from gait experiments with ten young males and ten young females. Body motions were captured using eight video cameras, and the corresponding angular displacements of the neck and the upper body and lower extremity were computed by motion analysis software. The maximal Lyapunov exponents for eleven joints were calculated from attractors constructed and then were analyzed statistically by one-way ANOVA test to find any difference between the genders. This study shows that sexual differences in joint motions were statistically significant at the shoulder, knee and hip joints.

  • Morphological differences were studied using the analysis of variance between various partial length and shell length of three populations of Saxidomus purpuratus on the Korean waters. The Relative growth equations, that is, SH-SL, SW-SL, TW-SL of S. purpuratus by sex were estimated. The analysis of variance of four morphological characters proved that each population has no sexual differences (p>0.01). But the three populations are significantly different in morphological characters (p<0.01).

  • We investigated the pollinators of Centipede's foot orchid (Cleisostoma scolopendrifolium) at five locations in southern Korea. Only one species of megachilid bee (Megachile yasumatsui) was observed at three of the sites (Mokpo, Haenam, and Wando). We assumed that the megachilid bee worked as a sole pollinator of C. scolopendrifolium based on the visiting behavior of the bees the attached pollinia. Fruits were observed at the three locations that bees visited: 74% fruit set at Mokpo, 59% at Wando, and 31% at Haenam. By contrast, at two of the locations where megachilid bees did not visit the plants (Naju and Jindo), there were no fruits set. The differences in fruit set rates at the three orchid populations where bees were observed appear to be related to bee abundance and flower visitation rate rather than to differences in flower abundance. The pollination interaction between C. scolopendrifolium and megachilid bees appears to involve sexual deception since only male bees were attracted to the flowers. The underlying mechanism involved in this interaction needs investigation.

  • This study was designed to measure the physical, mental-emotional and social health status of elderlies according to rural areas, medium - small cities, and large city environment. Data collection was done from July 18 to August 17 1990. The subjects were a convenience sample after their place of residence was stratified into large, medium- small cities and rural areas. Those who attended elderly centers in Seodaemun, Mapo, and Kangnam districts in Seoul were considered to be residents of a large city and interviewed by trained research assistants and student nurses. Elderlies living in Chungju, Jinju, Chuncheon, and Jeonju cities were coded as residents of medium-small cities and were interviewed by professors of nursing colleges. Rural residents were interviewed by the community health practioners working in community health clinics in North and South Kyongsang, North and South Jeolla, and Kyonggi provinces. The tool used in this study was the health assessment tool developed by Choi, Young Hee in 1990. This tool was organized into 20 physical health status, 17 mental - emotional health status, and 37 social health ststus items. Physical health status items consisted of six factors - personal hygiene activity ability, external activity utilizing traffic, mass media, and spare time ability, sexual ability, digestive system related ability, sexual ability, sensory ability, and elimination ability. Mental - emotional health status items consisted of two factors - mental health factor and emotional health factor. Social health status items consisted of seven factors -grandparental role ability, parental role ability, spoused role ability, friendship role ability, kinship role ability, group member role ability, and religious believer role ability. Data Analysis included frequencies, percentage, mean, standard deviation, ANOVA, and chi - square test. The results of the analysis are as follows : 1. The mean physical health status score for large city residents was 4.1132, for rural residents 4.0787, and for medium and small city residents 3.9565. There were significant differences according to residential area for personal hygiene activity ability, external activity ability, sexual ability, and digestive system related ability items 2. The mean mental -emotional health status score for rural residents was 3.8291, for medium and small city residents 3.7967, and for large city residents 3.7807. There was a significant difference according to residential area in the mental health ability item. 3. The mean social health status score for medium and small city residents was 3.0000, for rural residents 2.9362, and for large city residents 2.8960. There were significant differences according to residential area for kinship role ability and religious believer role ability items. The following conclusion was derived from the above results 1. The physical health status of elderlies residing in medium - small cities and in rural areas was lower than that of those residing in Seoul, a large urban area. Therefore, more medical facilities are needed in rural area so as to monitor their health, prevent disease, and promote their health. 2. The mental -emotional ststus and social health status of elderlies residing in the large city were lower than that of those residing in medium - small cities and rural areas. This may reflect weakening of the strong traditional family bond that may happen with urbanization. Continued support for elderly parents is essential and education should emphasize the traditional cultural norm and value of filial piety. 3. Facilities and programs for elderly are needed so that they may spend their time more valuably in their urban environment.

  • 본 연구는 남녀의 병리적 자기애와 데이트폭력 가해의 관계에서 거부민감성의 매개효과를 규명하고, 각 변인에 있어서 성차가 있는지, 매개 경로를 성별이 조절하는지 검증하고자 하였다. 이를 위해 전국에 거주하는 20대 성인남녀 381명을 모집하여 병리적 자기애, 거부민감성, 네 가지 유형의 데이트폭력 가해 경험에 대한 온라인 자기보고 설문을 실시하였다. 성별에 따른 차이를 검증한 결과 여성은 남성에 비해 자기애적 취약성과 거부민감성 수준이 높고 심리적 폭력, 성적 폭력, 통제행동을 더 많이 하는 것으로 나타났다. 매개분석 결과 병리적 자기애가 심리적 폭력, 통제행동에 미치는 영향에서 거부민감성이 부분매개 역할을 하였으나, 성적 폭력에 미치는 영향에서는 완전매개 효과를 보였다. 반면 병리적 자기애와 신체적폭력의 관계에서 거부민감성의 매개효과는 나타나지 않았다. 다음으로 이 매개 경로에서 성별의 조절효과를 측정한 결과 자기애적 웅대성과 자기애적 취약성이 거부민감성을 매개로 통제행동에 미치는 영향에서 성별의 조절된 매개효과가 검증되었다. 이 같은 결과는 남녀 모두 병리적 자기애가 심리적 폭력, 성적 폭력을 촉진하며 이 과정에서 거부민감성이 매개변인으로 작용한다는 것을 보여준다. 또한 병리적 자기애가 거부민감성을 통해 통제행동 가해에 미치는 영향이 남성보다 여성에서 유의하게 높아 매개 경로에 성차가 있음을 나타낸다. 마지막으로 본 연구의 시사점 및 제한점과 후속 연구를 위한 제언이 논의되었다.

  • Purpose: This study was done to compare health risk behavior prevalence for youth living in metropolitan, medium sized and small cities or rural area, in order to enhance understanding regional differences. Methods: For this study, data from the 2006 Youth Health Risk Behavior Online Survey collected by the Korean Center for Disease Control were analyzed using SPSS. Results: In the metropolitan areas, prevalence for disease and perceived obesity were higher than in other areas. Lack of intense or moderate physical activity, obesity, fast food intake, and insufficient sleep showed higher prevalence than in rural areas. Prevalence of lifetime smoking, lifetime alcohol consumption, present alcohol use, fruit intake less than once a day, and not wearing a seat belt were higher in rural areas than in urban areas. Gender, smoking, and alcohol use were correlated. Spearman correlation between living with parent and skipping breakfast were significant. Smoking, alcohol use, and sexual behavior were correlated. Conclusion: As significant differences in prevalence of youth health risk behaviors exist between regional areas, health education and health promotion programs considering these differences have to be developed and implemented for adolescents. Programs for prevention of smoking and alcohol use, programs for improvement of fruit intake and safety are suggested for adolescents in rural areas, whereas programs to enhance physical activity and obesity management are suggested for adolescents in metropolitan areas.

  • The purpose of this study was to investigate the differences in traditional baby-delivery practices between young mother and grandmother generations. The subjects were 118 young mothers and 118 their own mothers or mothers-in-law in Tae Gu district. Young mothers had the first baby aged from 2-to 2.5-year-old. The subjects answered the questionnaires on Korean traditional baby-delivery practices developed by the researchers based on literature reviews. The data were analyzed using Frequencies, Percentages, Crosstabs, and t-test. The results of this study were as follows: 1. More grandmothers believed in supernatural being who influenced pregnancy and used to be called as 'grandma Sam Shin', expected to have son, and had charms then young mothers. But less grandmothers had sexual intercourse at the time of ovulation, took physical care, and practiced fetal education than young mothers 2. On the other hand, no generation differences were found in dreaming of foretelling conception(Te Mong), eating a restroative and food to get pregnancy, and washing own's hair or body and avoiding attending a funeral near the time of baby-delivery. 3. Most of young mothers gave birth in hospital with the doctor's heap, whereas most of grandmothers did at their home with the help of the experienced old women. Most of young mothers'husbands were at the waiting room in the hospital, but about half of grandmothers'husbands were at work when their wives grove birth.

  • This study was designed to analyze normal nasal respiratory resistance in prepubertal children. The subjects consisted of 30 prepubertal children (male: 15, female: 15). The mean age was 11.4 years in male children and 11.5 years in female children. The results were as follows: I. The normal nasal respiratory patency was lower than the normal values from RION corp. 2. The normal nasal respiratory airflow rates showed no sexual differences. And there were no differences between inspiration and expiration. 3. Before and after use of nasal decongestants, there were no significant differences of normal nasal respiratory airflow rates and after the administration of nasal decongestants, nasal respiratory patency manifested lower variability. 4. The normal nasal respiratory resistance without nasal decongestants at 150 Pascal in inspiration was $0.30Pa/cm^3/sec({\pm}0.07)$ and peak nasal inspiratory airflow rate was $1016.83cm^3/sec({\pm}223.89)$. 5. The normal nasal respiratory resistance with nasal decongestant at 150 Pascal in inspiration was $0.25Pa/cm^3/sec({\pm}0.05)$ and peak nasal inspiratory airflow rate was $1148.33cm^3/sec({\pm}234.29)$.
