To investigate the prevalence of Toxoplasma gondii in pork on the market in Korea, an in-house enzyme-linked immunosorbent assay for tissue fluid (CAU-tf-ELISA) was developed using a soluble extract of T. gondii RH strain tachyzoites. As the standard positive controls, the piglets were experimentally infected with T. gondii: Group A (1,000 cysts-containing bradyzoites), Group B (500 cysts-containing bradyzoites) and Group C ($1.0{\times}10^3$ or $1.0{\times}10^4$ tachyzoites). The CAU-tf-ELISA demonstrated infection intensity-dependent positivity toward tissue fluids with average cut-off value 0.15: 100% for Group A, 93.8% for Group B and 40.6% for Group C. When tissue-specific cut-off values 0.066-0.199 were applied, CAU-tf-ELISA showed 96.7% sensitivity, 100% specificity, 100% positive and 90.0% negative predictive values. When compared with the same tissue fluids, performance of CAU-tf-ELISA was better than that of a commercial ELISA kit. Of the 583 Korea domestic pork samples tested, anti-T. gondii antibodies were detected from 9.1% of whole samples and 37.9% from skirt meat highest among pork parts. In the 386 imported frozen pork samples, 1.8% (skirt meat and shoulder blade) were positive for anti-T. gondii antibodies. In Korea, prevalence of anti-T. gondii antibodies in the pork on retail markets appeared high, suggesting that regulations on pig farming and facilities are necessary to supply safe pork on the tables.

Purpose: The purpose of this preliminary study was to investigate gender equality consciousness among elementary school teachers and the 6th graders at 3 rural area in Korea. Methods: There were 78 teachers and 323 6th graders from five elementary schools in Y area in Jeonnam province. The data was collected with 3 structured self-reported questionnaire from June to July 2003. The instrument, which was developed by Korean Women Development Institute to test gender equality consciousness, was composed of 20-items (Cronbach's ${\alpha}$ = .87 in teachr group; Cronbach's ${\alpha}$ = .83 in children group) with four subcategories: family life, school life, business life, and social life. The data was analyzed by a one-way ANOVA and t-test using SPSS/PC+. Results: 1. Teachers' gender equality consciousness: The teachers' gender equality consciousness was significantly more affirmative in females (t = 5.313, p = .001) and in the younger teacher group (F = 24.710, p = .001). On the other hand, there was no significant difference according to marital status. The differences in all four subcategories were also significantly affirmative in the female and younger teacher group. 2. Students' gender equality consciousness: The gender equality consciousness among the 6th graders was somewhat different from the teachers'. School girls (t = 8.988, p = .001) and children from double income families (t = 3.171, p = .042) were more affirmative in gender equality consciousness than the other groups. In the four sub-categories, school girls were also significantly more affirmative in all four subcategories. On the other hand, according to the family income source, the children from double income families also tended to be more affirmative only in the subcategory of family life (t = 3.196, p = .042) Conclusions: Gender equality consciousness is remarkably different according to gender both in Korean elementary school teachers and in school children. Age was a key variable in teachers for gender equality consciousness. Further research in gender equality consciousness of parents, school principals and urban school population would be useful. In order to promote gender equality consciousness, various educational materials and a mass education campaign should be developed.

Instroduction: The purpose of this study was to investigate safety education-related backgrounds and safety behaviors of elementary school children at a local area in Jeonbuk province. Methods: Study subjects were 308 5th and 6th graders from 6 schools located in J City and the data were collected from June 16-27, 2003. Research instrument to test safety behaviors was 4-points summated scale (Cronbach${\alpha}$= .94) composed of 54-items with three sub-categories school life safety (${\alpha}$= .88), traffic safety (${\alpha}$= .86), and daily life safety (${\alpha}$= .84), The data was analyzed by percentage, x2-test, t-test, ANOVA and Duncan test using SPSS/PC 10.0. Results: 1. Safety Education-related Characteristics: Safety education was mostly conducted during extracurricular hour as picnic (37%) and regular class (37.2%); and the instructors of safety education were school nurse (33.2%), classroom teacher (30.9%), and parents (23.4%) in order. About two third (71.0%) of the subjects have had many kinds of school event program such as essay writing, poster drawing, oratorical contest in the course of safety education According to gender, girl students was more favorable about school events as a effective safety education measure (x2=9.188, p= .010); and according to school location, nural school taught more at moming & closing session (x2=7.383, p= .025), by school nurse or classroom teacher (x2=36.574, p= .001), and had more frequent (x2=63.337, p= .001) safety education class. 2. Practice of safety behaviors: Mean scores of safety behaviors was $106.9{\pm}24.92$ out of 162 points. According gender, the scores of girl students (t=-3.296, p= .001) were significant higher than boy students. But there was not any significant difference according to school area According to safety education-related characteristics, the scores of safety behaviors was significantly higher in the group who thought that school event program was more effective on safety education (F=4.024, p= .019), and who were more interested in current safety education class (F= 10.203, p= .001) Conclusions: From the above findings, the authors concluded that school-based safety education was mainly conducted at extra-curricular and regular class, and by school nurse or classroom teacher in elementary school. Even though the mean scores of safety behaviors of elementary school children was in medium level, those. were significant higher in girl students and in rural school children. And extra-curricular activities and school event programs were suggested as more effective strategies for school-based safety education Based on the above findings, safety education class can be recommended in regular curricular basis; and various extracurricular activities and school event programs need to be developed for more effective school-based safety education. In addition, further study on gender-specific factors on safety behaviors and nationwide survey on school-based safety education should be needed.

These studies were carried out to find out the polishing properties and cooking quality of the cut-polished barley. Naked barley, Youngsanbori which was produced in Chonnam province, Korea in 1981, was applied for this experiment. Polished barley was produced by the conventional method and cut-barley was manufactured by the method established by Wheat and Barley Research Institute. The yield of cut-polished barley was 68.2% and that of conventionally polished barley was 70.1 %. The ratio of length to width was 2.88 in cut-polished barley and that of conventionally polished barley was 1.36. And weight of 1,000 kernel was 9.5g in cut-polished barley and 18.5g in conventionally polished barley. Energy consumption was found to be 91.1kW/1,000kg in conventionally polished barley and 105kW/1,000kg in cut-polished barley. Whiteness, water uptake ratio and expanded volume of cooked barley were 45.5, 225.7 and 283% in conventionally polished barley and 49.5, 312.7 and 318% in cut-polished barley, respectively.

The effect of circumvaginal muscle(CVM) exercises to improve sexual function in married women has not been investigated by currently acceptable research methods, nor have appropriate instruments and techniques to carry out such investigation been available. The purpose of this research was to study the effect of CVM exercise on sexual function, and of measuring CVM function after CVM exercises. The research tools used were a modified Derogates Sexual Function Inventory questionnaire and a pressure sensitive intravaginal balloon device. This research was conducted in Kwangju-city and Chonnam province, Korea from July, 1994 to July, 1995. The research used a non-equivalent control pre-post test quasi-experimental design. Forty-five healthy married female volunteers, aged 30-58, and were randomly assigned by age using the matching fixed-length blocks to two groups. The experimental group consisted of 21 women who were assigned a 25-minute per day CVM home exercise program for six weeks. The control group of 24 women did not do the CVM home exercises. The CVM home exercise was developed by Dougherty(1989a) and adopted to Korea by Lee (1993). Data were analyzed by $x^{2-}$test, Paired t-test, Spearman product-moment correlation using SAS /P $C^+. The results are summarized as follows : 1. There were no significant differences in the characteristics of the subjects between the experimental and control groups before the CVM home exercises. 2. Hypothesis 1 that married women who participated in CVM home exercises would have higher mean scores on the sexual function(SF) than in those who did not participate in home exercise was supported. 3. Hypothesis 2 that married women who participated in CVM home exercises would have higher vaginal pressure on SF than in those who did not participate in home exercises was supported (mean maximum pressure, t＝－7.338, P＜.0001, peak maximum pressure, t＝－11.164, P＜.0001). 4. Hypothesis 3 that the more often(number of days) and the more frequent (numbers of time per day) that married women do CVM home exercise, the higher their mean scores on SF and vaginal pressures was supported（r＝0.233, P＜.01 ; r＝0.352, P＜.05）. A six week CVM home exercise program using a tape recording showed that SF can be improved. Results of this study showed that married women who exercise on a regular basis for six weeks improve their sexual function and increase the mean vaginal pressure and peak maximum pressure (tested by electronic monitor). In conclusion, CVM exercise is effective in increasing SF.SF.

This study investigated the influence of life satisfaction, accomplishment value, peer attachment, and relationship with teachers on the self-esteem of adolescents in three time points. The study population consisted of a nationally representative sample of middle school 1st grade students who completed the Korean Children and Youth Panel Survey(KCYPS) of the National Youth Policy Institute in 2010, 2012, and 2014. Descriptive statistics used included frequency, percentage, average, and standard deviation; in addition, reliability, repeated measure ANOVA, and regression results were reported using SPSS statistics. The results were as follows. First, this study showed that the longitudinal changes of self-esteem, life satisfaction, accomplishment value, peer attachment, and relationship with teachers were significantly different across three time points. Second, longitudinal changes in adolescents' self-esteem, life satisfaction, peer attachment, and relationship with teachers differed by gender, but accomplishment value did not. Third, life satisfaction was the most influential to self-esteem and peer attachment was the second most influential in the three data sets after controlling for gender, parents' academic attainment, and residential area. The influence of life satisfaction on self-esteem decreased across the three time points, but that of peer attachment increased over time. Instruction on life satisfaction and peer attachment needs to be more highlighted in Home Economics classes to enhance the self-esteem of adolescents.

Since the mid 1990s, policies have been actively promoted to improve safety and pedestrian environment around the school such as the improvement of School zone. However, the prevention of accidents was not effective because it did not extend to the school road where the main transportation route for children's commuting takes place. In addition, due to the rapid increase of automobiles, trunk road traffic in the peak time bypasses the back roads, which threatens children's safety and the environment by invading the school area, which is the main living space of children. In this study, the characteristics of domestic children's traffic accidents were investigated and the problems were analyzed by conducting a field survey on Yeouido Secondary School in Seoul and Unjung Elementary School in Gyeonggi Province. In addition, Variable speed limit signs and Beacons were installed in the pedestrian road of comunity including School zone, and the effects of facilities on the speed of vehicles were analyzed. As a result of the analysis, the Variable speed limit sign showed a deceleration effect of about 8.3km/h, and the Beacon showed a phenomenon in which the traveling speed of 0.8km/h increased only slightly. In addition, the traffic violation rate of passenger cars, buses, and lorries decreased by about 3% as a result of investigating the number of traffic violation vehicles before and after installation.

A growth trial was conducted to determine the optimal supplement of dietary magnesium hydrogen phosphate (MHP, $MgHPO_4$) which was manufactured from swine manure and phosphorus (P) requirements of juvenile carp Cyprinus carpio. Graded MHP of 0.5, 1.0, 1.5 and 2.0%, each was added to the basal diet (control) in lieu of cellulose to become the range of available P from 0.4 to 0.7%. The lowest weight gain (WG) and highest feed conversion ratio (FCR) were found in the control group (P<0.05). The group fed a diet supplemented with 2.0% MHP showed the highest WG, which was not significantly different from those of fish groups that received 1.0% and 1.5% MHP (P>0.05). The lowest FCR was observed in fish groups fed 1.5% and 2.0% MHP. Plasma inorganic P was significantly higher (P<0.05) in all fish groups fed MHP-supplemented diets than in control group. A second-order regression analysis on WG revealed that the optimum dietary MHP level and the available P (AP) requirement were found to be 1.85 and 0.66%, respectively. Expressed in terms of 'g AP intake per kg $BW^{0.8}$ per day', the AP requirement was found to be approximately 0.032 g/kg $BW^{0.8}/d$.
