For better understanding of population dynamics of Symplocarpus renifolius, some aspects of seed production were studied in natural populations for 3 years. The rate of reproducing plants (RP) was 8.06% among the whole studied. The RPs were 0.0% in leaf size class under 500cm2 per individual, and 3.6% in 500~1,000cm2, and 44.3% in over 3,000cm2. The resource allocated to sexual organ was 11.6% of total biomass at the end of growing season, and that to belowground was about 80% regradless of presence or absence of sexual organ. In the previous and the next years of seed production, the energy allocated to sexual organ didn't affect the changes of leaf size, year by year. After flowing season. Especially, a large number of sex organ were degraded in April, a period of pollination and fertilization. The number of seeds per individual was degraded in April, a period of pollination and fertilization. The number of seeds per individual was 13~22 and didn't relate to leaf size. But the weight per seed increased along leaf size per individual. Therefore, in S.renifolius population, large individual produced large seeds rather than many seeds.

Objective : The explanations regarding the function, region, and related internal organ and meridian of Jonggeun as discovered in historical texts were studied in an attempt to understand the true concept of Jonggeun. Method : Texts were searched to extract sentences that are relasted to Jonggeun, and these were used to categorize and analyze the area, related meridian and organ, function, and disease symptom. Thereafter, how Jonggeun affects the whole body and the regions of Jonggeun were contemplated. Result & Conclusion : Jonggeun can be divided into what is related to sexual intercourse, and into sokgol and Ligigwan. Here, things related to sexual intercourse explains the function of penis arousal. The functions of Sokgol and Ligigwan signifies that they serve as the base points for the body when it exercises, and they cooperate with Chungmaek to provide blodo and vitaility to body joints. There are two major differing opinions regarding the region of Jeonggeun. One explains that it exists within the genitalia, and the other sees fit to believe that it exists within small abdomen. Considering the functions of Sokgol and Ligigwan, it is right to view that Jonggeun exists around Gigahyeol, and the view limited to genitalia only considers Jonggeun around sexual intercourse.

Sexual health education for the patients is an independent function as well as a professional responsibility of nurses. Education should be based on the needs of patients in order to be successful and effective. Therefore nurses must identify sexual health education needs of their patients. A sexual health education protocol for hysterectomy patients was developed by the researcher for this study and included physiosexual and psychosexual topics as well as the topic of sexual interaction. The subject pool was composed of 108 post op total hysterectomy patients who had undergone doing a hysterectomy 5 to 10 days previously at 5 hospitals located in the Seoul and Kyunggi-do area from July 23 to September 30, 2001. The questionnaire was composed of 60 items on sexual health education and used a Likert-type 4-point scale. Internal consistency of this questionnaire in this study was cronbach's $\alpha$=.9495 for sexual health educational needs. For data analysis, the study executed a t-test, ANOVA, and Duncan's Test, in accordance with the purpose of the study using SPSS/PC Win 10.0. The results were as follows: The need for education was highest in the psychosexual area (3.38 point) with education related to sexual interaction the lowest (3.20 point). Osteoporosis (3.75 point) was ranked overall as the highest area of educational need. The degree of educational need varied in correlation with other characteristics of the patients including age, status of marriage, duration of marriage, religion, academic career, monthly income, occupation, the number of children age of menarche, menstruation, other diseases except gynecological disease, previous genital organ operation experience, disease discovery method, pre-explanation for the hysterectomy, average sexual intercourse frequency, how to acquire sexual health information and previous sexual health education (p<.05). In conclusion, the degree of sexual health education needs of hysterectomy patients was very high. Therefore, sexual health educational programs planned according to characteristics of the participating women is necessary.

이 글은 $\ulcorner$청구영언$\lrcorner$에서 남녀의 생식기를 지칭하는 '연장'이 등장하는 만횡청류를 재론하는 데 목적이 있다. 재론한 결과로, 남성화자는 큰 연장(대물), 여성화자는 작은 연장을 바라고 있었다. 연장의 크기로 보면 남녀의 경향이 상반된 듯하지만 서로에게 성적 만족을 주고 받아야 한다는 생각 즉 '여합부절(如合符節)을 향하고 있다는 점에서는 일치한다. 그래서 $\ulrcorner$얽고검고??큰구레나롯그것조차길고넙다$\sim$(#1993, *569)$\lrcorner$를 '남성에 의해 일방적으로 훼손당하는 여성의 성'으로 이해하기보다 남편과 자신의 '연장'크기에 대한 만족과 그에 따른 '여합부절(如合符節)'을 자랑하는 것으로 파악할 수 있었다.

The purpose of this study is to identify the relationship between sexual attitude and risk behaviors, between risk behavior and sexual experiences in Korean girls high school students. The subjects for this study were 522 girls, who were samples from a target population of 63,375 11th grade students from 200 regular high schools and 70 vocational high schools in Seoul. The data were collected from June 22 to July 18, 2002. A structured questionnaire was used that included measurement of general characteristics, sexual attitudes, risk behaviors and sexual experiences. The data were processed with the SAS program, which uses descriptive statistics, t-test, and ANOVA in its an alyses. The results of this study are as follows : 1. The frequency of sexual experience is as follows ; 'holding hands' had the highest percentage, 57.4 7%, followed in order by 'arms around' 50.19%, 'act of embracing' 50.19%, 'kiss' 37.74%, 'french kiss' 30.84%, 'touch breasts' 8.62%, 'touch sexual organs' 3.26%, 'coitus' 2.30%, 'contraception' 0.77%, 'pregnancy' 0.19%, 'abortion' 0.19%, and 'prostitution' 0.19%. 2. The score of conservatives types was significantly different depending upon exposure to pornographic material and drinking. In comparison, the score of permissiveness types was significantly different depending upon exposure to pornographic material, drinking, and running away from home. But the score of pleasure seeking types was not significantly different than that of the risk behaviors types. 3. There was statistically significant difference in the sexual experience depending upon exposure to pornographic material, drinking, smoking, and running away from home. 4. In the relationship between sexual attitude types and sexual experience, there was a negative correlation between the conservatives types and sexual experiences such as 'holding hands', 'arms around', 'act of embracing', 'kiss', 'french kiss', 'touch breasts', 'touch sexual organs', and 'coitus'. There was a positive correlation between the permissiveness types and sexual experiences such as 'holding hands', 'arms around', 'act of embracing', 'kiss', 'french kiss', 'touch breasts', 'touch sexual organs', and 'coitus'. There was also a positive correlation between the pleasure-seeking types and sexual experiences such as 'touch sexual organ', 'contraceptions', 'pregnancy', and 'prostitution'. Based on the finding of this study, this society should develop a integrated program to prevent risk behaviors and sexual experiences in girls high school students.

Background: The aim of this study was to clarify the relationship between the sexual reproduction and the resource allocation in a natural Polygonatum humile population grown in a temperate mixed forest gap. For this aim, the plant size, the node which flower was formed, the fruiting rate, and the dry weight of each organ were monitored from June 2014 to August 2015. Results: Firstly, in 3-13-leaf plants, plants with leaves ${\leq}8$ did not have flowers and in plants with over 9 leaves the flowering rate increased with the number of leaves. Among plants with the same number of leaves, the total leaf area and dry weight of flowering plants were larger than those of non-flowering plants. The minimum leaf area and dry weight of flowering plants were $100cm^2$ and 200 mg, respectively. Secondary, the flowers were formed at the 3rd~8th nodes, and the flowering rate was highest at the 5th node. Thirdly, cumulative values of leaf properties from the last leaf (the top leaf on a stem) to the same leaf rank were greater in a plant with a reproductive organ than in a plant without a reproductive organ. Fourthly, fruit set was 6.1% and faithful fruit was 2.6% of total flowers. Biomasses of new rhizomes produced per milligram dry weight of leaf were $0.397{\pm}190mg$ in plants that set fruit and $0.520{\pm}0.263mg$ in plants that did not, and the difference between the 2 plant groups was significant at the 0.1% level. Conclusions: P. humile showed that the 1st flower formed on the 3rd node from the shoot's base. And P. humile showed the minimum plant size needed in fruiting, and fruiting restricted the growth of new rhizomes. However, the fruiting rate was very low. Thus, it was thought that the low fruiting rate caused more energy to invest in the rhizomes, leading to a longer rhizome. A longer rhizome was thought to be more advantageous than a short one to avoid the shading.
