The purpose of this study was to analyze and identify the higher-grade primary school children's needs for sexual education. We got the data with open question from 481 children from March to July 1999. We analyzed them according to the framework suggested by the Sex Information and Education Council of USA. The framework involves the six domains such as human development, relationship, personal skills, sexual behavior, sexual health, and society & culture. In the analysis of need for sexual education according to domain, need for human development was highest (79.2 ％), after that followed society & culture (8.3 ％), sexual health (5.8％), sexual behavior (3.6％), and relationships (3.1％). There was no need for personal skills. By topics, there were needs for puberty (38.0％), reproduction (32.5％), gender roles (6.0％), body image (4.9％), sexual abuse (2.4％) and reproductive health (2.4％). Girls and boys all mostly wanted to know human development 41.0 ％ and 38.2 ％ each. Society & culture (3.4 ％), sexual behaviour (2.7％), sexual health (2.6％), relationship (2.4％) were domains selected by boys. Girls wanted to know society & culture (4.9％) and 'sexual health (3.2％). Comparing by grade, fourth, fifth and sixth grade children are commonly interested in development, society & culture. Fourth grade children scarcely show attention on the relationship, sexual behaviour and sexual health; meanwhile sixth grade children would like to know sexual behaviour and sexual health. When their grade became higher, they would like to know more precise, concrete and deep information. We suggest that the textbook/guidebook for sexual health for the higher-grade primary school children should be developed considering the sex and grade.

The purpose of this study is to investigate the drinking culture and attitude difference by gender and grade of Korean college students. A questionnaire was conducted to analyze the characteristics and meaningful differences by two variables about drinking pattern, culture and related policies. The analysis showed that regardless of gender, far more students were against than in favor of prohibition on drinking within campus, whose legislation recently failed. Meanwhile, there was a significant difference by grade in victimization experience regarding drinking within the campus, and by gender in frequency, beverage type, volume, onset of drinking within school. There was no statistically significant gender-based difference in response to experience of damage caused by drinking, but the research results of the related papers show that the female students are more dangerous and need special attention and care. Universities should implement a professional counseling program that is customized according to gender or level of education, and managed by group. Moreover, health authorities must seek a way to lead this move, such as providing incentives to the universities, which efficiently deal with students' drinking problem. And the prohibition on drinking within campus, whose legislation recently failed should be reconsidered.

This study was conducted to investigate the difference of general feature and ginsenoside content of 6 years old ginseng root among different grade of roots. Total weight of a 1st grade-6 years old ginseng root was 115.1g and weight, length, diameter and specific gravity of main root were 64.68g, 8.39cm, 3.31cm and 0.96, respectively. Main root of 1st grade ginseng root was larger in size and specific gravity and more heavy than that of End or 3rd grade of the roots. Though crude saponin contents were not so different among the different grade of roots, but ginsenoside Rb1, Rg1 and Re content were higher in 1st grade of root than that of 2nd or 3rd grade of root. Those ginsenosides were located mainly in periderm and cortex.

This experiment was investigated the effect of presence of granulosa cells from follicles of different size on bovine oocyte maturation, cleavage and development to late stage. The nuclear and cytoplasmic maturation of oocytes in the IVM-IVF system are critical for subsequent embryo development. Granulosa cells when the co-cultured with oocytes may interact with cumulus-oocytes complexes and influence the development competence of the oocytes. Granulosa cells from medium (2~6 mm) and large(>1O mm) size follicles were recovered by aspiration, washed 3 times by centrifugation at 500 x g for 5 min. and used for co-culture at a concentration of 2~3 x 106 cells/mi. The oocytes were matured in vitro (IVM) for 24 hrs. in TCM-199 supplemented with 35 $\mu$g/ml FSH, 10 $\mu$g/ml LH, 1 $\mu$g/ml estradiol-17$\beta$ and granulosa cells at 39$^{\circ}C$ under 5% $CO_2$ in air. They were fertilized in vitro (IVF) by epididymal spermatozoa treated with heparin for 24 hrs., and then the zygotes were co-cultured in vitro (I VC) with bovine oviductal epithelial cells for 7 to 9 days. The assessment of maturation revealed that Grade J oocytes showed significantly(P

Purpose: The purpose of this study was to empirically test a model of associations linking locations and competition among nursing homes (NHs), mediated by facility grade and registered nurse (RN) turnover, on activities of daily living (ADLs) in Korean NHs. Methods: This study used a cross-sectional design to identify causal factors on NH residents' ADLs. Data were collected from June 2017 to August 2017. A disproportionate stratified cluster sampling method of NHs across Korea was used to gain representation. The collected data consisted of location and the Herfindahl-Hirschman Index (HHI), RN turnover rate, facility grade, and NH residents' ADLs. Results: All pathways affecting ADLs were not significant, and the effect on facility grade was significant in RN turnover (β = -.59, p < .001). RN turnover associated negatively with facility grade. In other words, the higher the RN turnover, the worse the facility grade. Conclusion: This study is the first to examine the impact of location and HHIs, mediated by RN turnover rate and facility grade, on NH residents' ADLs. To improve residents' ADLs, subsequent studies are needed to identify the factors affecting ADLs utilizing other variables because this study did not identify factors that affect ADLs.

Purpose: The present study aimed to develop guidelines regarding initial choice of antibiotics for diabetic foot ulcers (DFU) by investigating bacterial isolates. Materials and Methods: This study included 223 DFU patients that visited a single tertiary hospital and underwent bacterial culture between January 2016 and February 2020. The study was conducted in two parts: 1) to compare bacterial isolates and wound healing according to comorbidities such as chronic kidney disease (CKD) and peripheral artery disease (PAD), and 2) to compare bacterial isolates according to wound depth using the Wagner classification. Results: Of the 223 patients, 43 had CKD (group A), 56 had PAD (group B), 30 had CKD and PAD (group C), and 94 had none of these comorbidities (group D). The isolation rate for multidrug-resistant gram-negative bacteria (MRGNB) and gram-negative to gram-positive bacteria ratio were highest in group C (p=0.018, p=0.038), and the proportion that achieved wound healing was lowest in group C (p<0.001). In the second part of the study, subjects were classified into 5 grades by wound depth using the Wagner classification; 13 grade I, 62 grade II, 60 grade III, 70 grade IV, and 17 grade V. No significant difference was observed between these grades in terms of isolation rates or gram-negative to gram-positive bacteria ratios. Conclusion: This study suggests antibiotics that cover gram-negative bacteria including MRGNB produces better results in the presence of CKD and PAD and that initial antibiotic choice should be based on the presence of CKD and PAD rather than wound depth.

The nudear changes of bovine oocytes during 24 hrs. of culture for mejotic maturation were examined. Bovine oocytes were collected from small(<2 mm), medium(2~6 mm) and large(>6mm) follicles and classified into three grades by their morphological characteristics. A total of 242 oocytes collected were obtained:from 184 small, 157 medium and 1 large follicles, respectively and were classified into 95 grade I, 155 grade H and 92 grade III oocytes. All the bovine oocytes collected and graded were washed with a basal medium and incubated in groups of 10 for 24 hrs in 5% $CO_2$ and 39$^{\circ}C$. The basal medium used was composed of TCM-199 supplemented with sodium bicarbonate, sodium pyruvate, streptomycin, penicillin G and 10% FCS. The oocytes were cultured in drops of 50,$\mu$l basal medium supplemented with 35$\mu$g /ml FSH, 10$\mu$g /ml LH and 1$\mu$g /ml estradiol-17$\beta$. The oocytes were fixed and examined on their chromosomal status by 1% acetorcein staining in the interval of 3 hrs. Most of the grade I oocytes developed to germinal vesicule stage at 0 to 3 hrs., germinal vesicle breakdown at 6 hrs., metaphase I at 9 to 15 hrs., anaphase I and telophase I at 18 hrs., and metaphase II and the first polar body at 24 hrs. after culture for meiotic maturation. However, it was found that compared to grade I oocytes, grade H and W oocytes reached earlier to germinal vesicle breakdown and most of them developed earlier to M II stage at 21 hrs. after culture.

This study was conducted to investigate the effects of 10-week dietary education on elementary students in an after-school program in Seoul. Participants were 20 1-2 grade students and 283-6 grade students, and the dietary program consisted of dietary education and activities focused on children's levels of understanding. The results were as follows: Total participant's food habit scores and nutrition knowledge significantly increased (p<0.05) after dietary education. Food habit and nutrition knowledge scores of lower grade participants (grade) increased desirably (p<0.05). Meanwhile higher grade participants' (grade) food habit scores also changed (p<0.05), but their nutrition knowledge scores were changed. Boy's food habit scores significantly changed (p<0.05), whereas girl's food habit scores did not change significantly. Further, female participants' nutrition knowledge scores did not changesignificantly after education. Participants' obesity knowledge scores significantly changed after the education (p<0.05), but their attitudes on obesity increased insignificantly. Lower grade participants' attitudes on obesity significantly and desirably changed (p<0.05), whereas higher grade participants' attitudes on obesity changed insignificantly. Girl's knowledge and attitudes on obesity significantly and desirably changed (p<0.05-0.01). This study revealed the correlation between food habit scores and attitudes on obesity (p<0.01), demonstrating that participants with high food habit scores have advisable attitudes on obesity. The result of this study shows that lower grade participants' food habit scores, nutrition knowledge, and attitudes on obesity changed desirably after dietary education. Therefore, this study promote the development of adequate nutrition education and materials focused on lower grade students and the need for systematic and continuous dietary education programs based on elementary school.

This study was undertaken to assess grade and gender differences in dietary behavior, food preference and perception about body image of students in 4, 5 and 6th grades in elementary school in Kwangju. Anthropometric data showed that mean height and weight were $137.98{\pm}6.79cm\;32.69{\pm}6.09kg$, in the 4th grade, $144.11{\pm}6.91cm,\;36.88{\pm}7.60kg$ in the 5th grade and $151.52{\pm}7.47cm,\;42.68{\pm}8.06kg$ in the 6th grade. Height and weight of male and female students of each grade were very similar to those of the Korean standard Growth data. Females in the 5th and 6th grades were taller than those in male students, which suggested the height growth spurt in females. Furthermore, both genders showed marked variability even in the same group. All the three different obesity indices(BMI, Rohrer and % of ideal body weight) showed higher value in males than in females consistently. Male respondents desired taller and heavier body shape while females perceived they were heavy and desired only taller and thinner body image. There were significant differences in satisfaction with height, weight and body image by grade(p<0.05). 36.7% of subjects responded that they did not eat despite hunger. In higher grade they felt guilty after eating sweet things. Strikingly, it was noted a small number of students tried to take a diet pills or vomited on purpose. Data on food preference showed that female did not like sweet food and pork. While male students preferred red meat and chicken. Thus result indicated that there was a great difference in food preference by gender.
