본 연구는 성행동, 부모 및 친구와의 성 의사소통, 성태도 및 성지식 정도와 성행동에 영향을 미치는 요인을 파악함으로써 성건강 향상을 위한 성교육 프로그램의 기초자료를 제공하고자 시도되었으며, 2012년 3-4월 서울과 천안 소재 2개 간호대학에 재학 중인 간호대학생 218명의 설문지를 분석하였다. 연구결과 간호대학생의 성행동, 부모 및 친구와의 성 의사소통, 성태도 및 성지식 정도는 중간이상인 것으로 나타났다. 성행동은 부모와의 성 의사소통, 성태도 및 성지식과 부적상관관계를 나타내었고, 간호대학생의 성행동에 영향을 미치는 요인은 성 관련 정보의 출처, 성지식, 과거 이성교제 경험, 부모와의 성 의사소통 순으로 나타났다. 성문제는 삶의 다양한 측면에 영향을 미치므로 간호사는 성문제를 가지고 있는 대상자를 간호할 때 성문제에 대한 깊은 이해를 가질 필요가 있다. 따라서 간호대학생을 위한 성교육 프로그램은 부모와 친구를 포함한 개인간 접근 전략을 요구하며, 간호대학생 스스로 성건강 관리에 적극적으로 나설 수 있도록 유도해야 할 것이다.

This experiment was conducted with 30 adult wool producing Angora rabbits of either sex, to evaluate the effect of replacing soyflakes (SF), on equal protein basis, with low gossypol containing cottonseed meal (CSM) either alone or in combination with lysine and methionine; on the biological performance, total wool yield, wool yield per shearing, wool characteristics and mortality. Three experimental mash diets were prepared by incorporating SF (6%) as standard / control protein source $(T_1)$ and CSM (9%) as test protein source ($T_2$ and $T_3$). In $T_3$, amino acids-lysine and methionine (0.1 % each) were added. Animals were given the experimental diets about $150g{\cdot}day^{-1}{\cdot}head^{-1}$, for a period of 225 d or three shearing, and ad libitum Kudzu-vines. No significant effect of $T_2$ or $T_3$, on the body weight gain, total wool yield, wool yield per shearing and wool characteristics, was observed compared to $T_1$. However, the digestibility of dry matter, crude fibers, ether extract, acid detergent fibers, neutral detergent fibers, cellulose and hemicellulose was significantly (p<0.05) depressed in CSM based diets. Mortality of about 20% was recorded in $T_2$ and $T_3$, but not related to the addition of CSM or gossypol toxicity. More studies are needed to standardize the safe level of CSM, duration of safe feeding of CSM, and level of amino acids supplementation in CSM based diets.

This study was conducted to analyze the priority of environmental problems in Korea by investigating the environmental professionals' perception. The delphi technique was applied to identify their risk perception towards some specific items related with pollution. A standardized questionnaire on environmental problems and their priorities was used to 74 subjects. In the questionnaire, the environmental problems were divided into the general ones,9 items, and the specific ones,30 items. Also, the perception was associated with two points of view which were the risk on general human health or ecosystem, and on the present situation in Korea. The priority of risk from general environmental problems on human health or ecosystem was analyzed in the order of 'water pollution', 'air pollution', 'soil contamination', 'waste', 'toxic chemical pollutants', 'food contamination', 'ocean contamination', 'odor pollution', and 'noise pollution'. The priority of risk on the present situation in Korea was analyzed in the order of 'water pollution','air pollution','waste','toxic chemical pollutants','food contamination','soil contamination','ocean contamination','odor pollution', and 'noise pollution'. And these priorities were significantly related with the characteristics of respondents such as sex, age, and major concerned area. However, for the first five priorities of risk from the specific environmental problems on human health or ecosystem, the environmental professionals agreed with 'automotive vehicle exhaust', 'domestic and industrial source pollutants to surface water', '$CO_2$nd g1oba1 warming effect','toxic air pollutant' and 'industrial source air pollution'. The priorities of risk on the present situation in Korea were similar to these results.

The purpose of this study was to explore consumption status of scented textile products and to determine differences in consumption behaviors of scented textile products among subject groups separated by demographic (sex, age) and lifestyle (health concern, fashion involvement, innovativenss) characteristics. A total of 530 consumers who had used scented textile products participated in the web survey for the study. Consumer data were analyzed through descriptive statistics, chi-square test, factor analysis, t-test, ANOVA, and LSD test. In the results, the most often used products were small commodities, socks, bedding, and underwear of hub and flower scents. Consumers considered a product test as the most crucial information source and scent as the most significant decision making factor for purchase. Demographic and lifestyle group differences were found in some of the product types in use as well as in purchase behaviors (total spending amount, purchase venue, information source, considering factors when purchasing). The applicability of the study result to the theory of innovation adoption was discussed. Marketing implications were suggested based on the study results.

As an initial step toward the improvement of sexual education in middle school students, a survey on sexual attitudes and experience was done in Kangwon - Do, Korea. Questionnaires consisted of 68 items distributed to 240 boys and 240 girls from November 1 to December 20, 1996. Answers from 420 students were subjected to an analysis with SPSS. 92.4% of the girls experienced menstruation. Of them, 74.0% showed a negative reaction. 52.0% of the boys experienced night ejaculation. Of them, 81. 7% showed a negative reaction. Boys (64.3%) masturbated more than girls (17. 6%) (p= 0.0000). The understanding of masturbation was higher in boys than in girls (p = 0.0000). 87.2% of the subjects wished meetings with the opposite sex. During the meeting with the opposite sex, 12.9% of the students enjoyed drinking or smoking, 8.8% had intercourse. Boys(91.9%) watched pornography or porno-video more than girls(40.5%)(p=0.0000). 83.3% of the girls thought that both males and females should keep their virginity untill marriage. However, only 48.6% of boys thought that(p=0.0000). Of boys who had experienced sexual touch, 34.8% had intercourse. Of the 30 students(26 boys, 4 girls) who experienced sexual intercourse, 22 students had partners of the opposite sex and were friends. First intercourse 63.4% of these students had their in middle school period. The frequencys of sexual intercourse (more than 6times) was written by 12 students (40.0%). 24 students(16 boys and 8 girls) experienced sexual violence. As for dealing with sexual violence, 14 suffered by him or herself whill 7 students discussed it with a friend. There was a significant difference in the sources of information between boys and girls(p= 0.000), 36.0% had learned from an official sexual education source, usually from school nurses (74.0%). 92.6% of the students thought that sexual education was necessary. They believed that the appropriate person for sexual education was from a school nurse (53.1%) or from parents (19.5%). According to the above results, the following might be suggested: Realistic and future-directed sexual education material should be developed : Education programs to improve students insight and control sexual desire should be prepared: a systematic approach to activate the role of school nurse in sexual education should be prepared.

The three-way rotational crossing experiment has been conducted to evaluate heterosis effects on jumping height and body weight. Yonakuni wild mice (Y) and two genetic groups of $CF_{{\sharp}1}$ (C) and C3H/HeNCrj (H) laboratory mice were used as materials. Reciprocal rotational crossing was made by crossing C male${\times}$Y female and Y male${\times}$C female to produce basic group designated $G_0$ and ${G_0}^{\prime}$, respectively. The females of the $G_0$ and ${G_0}^{\prime}$ were mated to the H sire to produce second generation ($G_1$ and ${G_1}^{\prime}$), and at the following generation the replacement females were mated to Y or C sire according to the basic group to produce $G_2$ to $G_3$ and ${G_2}^{\prime}$ to ${G_3}^{\prime}$. Individual jumping height data at Wk6 and body weight data at 1 (Wk1), 3 (Wk3), 6 (Wk6) and 10 (Wk10) weeks of age were analyzed. The results showed that effects of genetic group, sex and interaction of genetic group by sex were significant (p<0.01) for jumping height. For males, 55.34%~79.17% and 54.46%~78.29% of heterosis were reached at $G_1$ to $G_3$ and ${G_1}^{\prime}$ to ${G_3}^{\prime}$, respectively. While for females at $G_1$ to $G_3$ and at ${G_1}^{\prime}$ to ${G_3}^{\prime}$, heterosis effects were 61.53%~80.42% and 47.79%~85.86%, respectively. For body weight, genetic group was a significant source of variation at all ages studied. Sex effect was significant at Wk3, Wk6 and Wk10, and interaction between genetic group and sex was significant at Wk6 and Wk10 (p<0.01). C sires resulted in the highest body weight of offspring, while H sires were the intermediate and Y sires were the lightest. The significant positive and negative heterosis effects for body weight were exhibited. Crossing involved the Y sires in addition to smaller maternal effects of Y dams tended to result in small heterosis.

The seroprevalence of human toxoplasmosis has been increasing in Korea, and it is controversial whether cats are an important infection source or not. This study was performed to evaluate the seroprevalence of Toxoplasma gondii infection in a high risk group (cat sitters) and to determine the possible importance of cats as an infection source in Korea. Risk factors, including the age, sex, and diet of cat sitters, their contact experience and contact frequency with stray cats, and origin, number, and outdoor activity of their pet cats, were analyzed using structured questionnaires. A total of 673 serum samples from people who have frequent contact with cats (high risk group) and 1,114 samples from general people (low risk group) were examined for specific IgG antibodies against T. gondii by ELISA. The results revealed that the overall seroprevalence of T. gondii infection was 7.4% (n=1,787). The seroprevalence among low risk group was 8.0% (89/1,114), whereas that among high risk group was rather lower 6.4% (43/673), though this difference was statistically not significant (P=0.211). Among the risk factors, only the outdoor activity of pet cats was important; people having cats with outdoor activities revealed 2 times higher seroprevalence than people having cats with only indoor activities (P=0.027). In conclusion, the seroprevalence of T. gondii was not significantly different between the high risk group and low risk group, and the importance of cats as a source of infection in Korea is questionable.

This experiment was conducted to determine the effects of enzyme supplementation on the performance of 80 growing-finishing pigs (26.2 kg) fed diets containing either soybean or canola meal. Barley-based diets formulated using either soybean meal or canola meal were fed with or without enzyme (Allzyme Vegpro, Alltech Biotechnology Centre). Eight castrates and twelve gilts were fed each diet. Digestibility of dry matter, crude protein and gross energy was 8.0 (p=0.0001), 7.9 (p=0.0005) and 7.9 (p=0.0003) percent lower for pigs fed diets containing canola meal compared with soybean meal. Enzyme supplementation had no effect on nutrient digestibility (p>0.05). There was a significant interaction between protein source and enzyme for all three nutrients. Over the entire experimental period (26.2 to 77.9 kg), pigs fed canola meal consumed 9.4% less feed (p=0.001), gained weight 20.4% slower (p=0.001) and had a 12.9% poorer feed conversion (p=0.001) than pigs fed soybean meal. Weight gain, feed intake and feed conversion were unaffected by enzyme addition (p>0.05). Castrates gained weight 11.4% faster (p=0.001), consumed 9.3% more feed (p=0.001) and had a 2.6% better feed conversion (p=0.026) than gilts. There was a significant interaction between protein source and sex of pig for feed conversion. Pigs fed diets based on canola meal had a significantly lower carcass value index (p=0.01), lower lean yield (p=0.007) and lower lean depth over the loin (p=0.001) than pigs fed diets based on soybean meal. Enzyme addition significantly increased lean depth over the loin (p=0.01). There was a significant interaction between protein source and enzyme for carcass value index (p=0.04), estimated lean yield (p=0.05) and fat depth over the loin (p=0.05). These results confirm previous studies which have demonstrated poorer pig performance when canola meal completely replaces soybean meal in diets fed to growing-finishing pigs. In addition, the results provide little justification for the inclusion of the Vegpro enzyme in diets fed to pigs of this weight range.
