  • The purpose of this study was to discuss the difference of stress by the grade, examine the relationship between characteristics and main stress, and to investigate the effect of the National Examination of Registered Nurses on stress by using the stress self-rating scale targeting university nursing students (n=314), The stress self-rating scale consists of three subscales: stress responses, stressors and coping parts, such as perceived social support and a sense of humor. The data were analyzed by descriptive statistics, t-test, Pearson's correlation coefficient and regression analysis. The results showed that passing the National Examination of Registered Nurses was the first problem among the stressors. Stressors of the living factors and nursing factors, and subjective stressors of the surveyed nursing students were the highest among the senior students, but stressors of nursing factors increased according to the grade of the nursing students. Perceived stress responses were high in psychological responses of other aspects, and perceived stress responses increased according to the grade (p<.001). Senior students had a high weight of perceived stress responses (problem-focused, emotion-focused). and active and negative coping modes. Significant factors that explained the stressors were coping mode(r=.62-82. p<.01) and cognition(r=.19. p<.01). including the social support. These findings suggest that social support was very important for seniors. and that we have to develop approaches to decrease stress according to the student grade for nursing education process.

  • A group of Hanwoo (Korean cattle) steers (n=14,386) was sampled from a commercial abattoir located in Seoul over one year period (spring, summer, autumn and winter) and their carcass traits were collected. Carcass traits assessed by an official meat grader comprised degree of marbling, meat color, fat color, texture and maturity for quality grade, and back fat thickness, ribeye area and carcass weight for yield grade. A heavier carcass with a higher marbling score, more red meat color and white fat color received better quality grade (p<0.05). Regression analysis showed that the marbling score was the strongest attribute (partial $R^2=0.88$) for quality grade. Lighter carcasses with a thinner back fat and larger ribeye area received higher yield grade score. The back fat thickness was the most negative determinant of yield grade (Partial $R^2=-0.66$). The slaughter season had a little effect on quality and yield grades. As slaughter weight increased, back fat thickness and ribeye area increased linearly, whereas marbling score reached its asymptotic level at approximately 570 kg. As a consequence, quality grade showed a considerable improvement up to 570 kg, but increases in slaughter weight afterward showed a little benefit on quality grade. There was a clear curvilinear relationship between slaughter weight and yield grade in that the yield grade reached its highest point at approximately 490 kg and decreased afterward. These results suggested that 570kg at the age of 24 months might be the economic slaughter weight for quality grade but 490 kg for yield grade.

  • This study was designed to develop the evaluation scale for health-grade of families. For this goal the related references and the programs of Healthy-Families-Center were analyzed. In the context with the goals and objects of programs in Healthy-Families-Center the index for the evaluation the health-grade of families was deducted. And the concrete items of health-grade of families in 3 parts(R: relation, M: management, E: environment) was discussed. In order to verify the validity and significance of the scale the survey for 200 samples was performed and the data from 191 samples was statistically analyzed. We suggested the application methods of this evaluation scale for health-grade of families. So the 8 types of families were came out: RME, RMe, RmE, rME, Rme, rMe, rmE, rme. Using this type of families the consulting and counselling for the enhancement of health-grade can be developed. We reached the conclusion that this evaluation scale has to be continuously developed and eleborated because the health-grade of families is one of the most important index for the effect of programs of Healthy Families Center.

  • An observational study was conducted to evaluate the effect of anterior pituitary gonadtropin on super-ovulation in donors, embryo quality, development stage of embryo, transfer location, corpus luteum quality of recipient, ease of transfer and induced versus natural estrus on pregnancy rates. The data were collected from 451 non-surgical transfers of fresh and frozen bovine embryos. 1. The average number of CL, formed in ovaries which were stimulated with follicular stimulating hormone, and/or APG, were 11. 1${\pm}$1.21, 12.3${\pm}$1.84, respectively. The numbers of embryos recovered were 8.2${\pm}$1.35, 8.7${\pm}$ 1.39, and the numbers of transferable embryos were 6.4${\pm}$0.98. 6.6${\pm}$1.01. respectively. 2 There was no effect of spontaneous versus prostaglandin-induced estrus of recipients on pregnany rates of either fresh (61.5% vs. 59.5%) or previously frozen(54.5% vs. 58.5%) embryos. 3. There were significant differences(p<0.05) in pregnancy rates for embryo grade 1(63.6%), grade 2 (45.4%) and grade 3 (30.4%) in fresh group and for grade-1 (60.5%), grade-2 (47.8%) and grade-3 (18.1%) in previously frozen embryos. 4. The recipients transfered with embryo morulae were found to have a lower (p<0.05) pregnancy rates than those transfered with embryos of blastocyst in be th fresh and previously frozen embryos. 5. There was no significant difference between transfer locations in pregnancy rates using both fresh and frozen embryos. 6. Attempts to select recipients for high pregnancy rates on the basis of corpus luteum (CL) quality were performed. CL were classified into 3 quality grades, on the basis of size and prominence. Quality grades 1 and 2 group had higher (p<0.05) pregnancy rates than grade-3 group using both fresh and frozen embryos. 7 Ease of transfer was ranked to a scale of one to three on the basis of increasing difficulty (time required). Transfers ranted as ease score 1 and 2 had significantly higher (P<0.05) pregnancy pregnancy rates (45.8%, 66.6%) than ease score 3 (27.7%, 31.8%) using both fresh and frozen embryos respectively.

  • This study examined the longitudinal effects of appearance satisfaction and Korean language skills on the self-esteem and school adjustment of multicultural adolescents. The study used data from 1,151 multicultural adolescents from the $3^{rd}$, $4^{th}$, and $5^{th}$ waves of the Multicultural Adolescents Panel Study (MAPS). Data were analyzed by means of descriptive statistics, Cronbach's alpha, correlation, and structural equation modeling. The results are as follows. First, appearance satisfaction and Korean language skills at grade 6 significantly predicted higher self-esteem at grade 7. Second, there was a significant influence of high levels of self-esteem at grade 7 on positive school adjustment of grade 8. Last, the self-esteem at grade 7 had a significant mediating effect in the relationship between appearance satisfaction and Korean language skills at grade 6 and school adjustment at grade 8. The results of this study highlighted the importance of self-esteem as a mediating factor in the connection between appearance satisfaction and Korean language skills as well as the level of school adjustment. This provides supporting evidence to many educators and parents for the implementation of effective support practices for multicultural adolescents to enhance their school adjustment. Other related implications of these findings and suggestions for future research are also discussed.

  • The effects of quality grade and storage time on physicochemical, sensory properties and microbial population of Hanwoo striploin beef were investigated. After a total of 30 Hanwoo beef were slaughtered, the cold carcasses were graded by official meat grader at 24 h postmortem. The carcasses were categorized into five groups (quality grade 1++, 1+, 1, 2, and 3) and were vacuum-packaged and stored. The samples were kept for 1, 4, 6, 8, 11, 13, 15, 18, 20, 22 and 25 d for analyses. As the quality grade was increased, moisture, protein and ash contents decreased (p<0.05). Higher quality grade corresponded with higher fat contents. The shear force values decreased with increasing quality grade and showed decreases sharply during the first 4 d (p<0.05). pH, water holding capacity, cooking loss, and volatile basic nitrogen for grade 1++ groups were lower than for grade 3 (p<0.05). CIE L* and b* values increased as increased quality grade (p<0.05). Meat color decreased until 13 d and fluctuated after 15 d of storage (p<0.05). Regarding the sensory scores, higher quality grade corresponded with higher juiciness, tenderness, flavor, fatty and palatability scores (p<0.05). Generally, increased storage time for 15 d improved sensory scores attributes. Results indicate that a high quality grade could positively influence physicochemical and sensory properties.

  • 본 연구는 음악영재의 학년수준에 따른 완벽주의, 스트레스, 그리고 진로결정 유형을 조사하고자, 예술 중학교에 재학 중인 음악영재를 대상으로, 다차원적 완벽주의 척도(Hewitt & Flett, 1991), 청소년 스트레스 척도(이정순, 1988), 그리고 진로결정 척도(Harren, 1984)를 실시하였다. 연구 결과, 음악영재의 학년수준에 따라 완벽주의 하위 요인에서- 자기지향, 타인지향, 그리고 사회적으로 부과된- 차이가 나타났다. 학년이 올라갈수록 음악영재의 완벽주의 성향이 강해지는 것으로 나타났다. 스트레스 역시 학년수준에 따라 유의한 차이가 나타나, 음악영재는 학년이 올라갈수록 자아발전, 부모자녀관계, 또래관계, 학교생활에서 스트레스를 점차 많이 경험하는 것으로 나타났다. 예술 중학교에 재학 중인 음악영재의 진로결정 유형에 미치는 학년수준의 효과는 합리적 진로결정 유형과 과도적 진로결정 유형에서만 나타나, 학년이 올라갈수록 합리적 진로결정 유형은 증가하나 과도적 진로결정 유형은 감소하는 것으로 나타났다. 한편, 음악영재의 합리적 진로결정 유형에 미치는 완벽주의와 스트레스의 영향을 조사하였을 때, 자기지향 완벽주의와 자기발전 스트레스 요인만 합리적 진로결정 유형을 유의하게 예측하는 것으로 나타났다. 이에 본 연구는 연구 대상자의 특징과 반응을 근거로 연구 결과를 논의하고 향후 상담 및 진로지도를 계획할 때 고려해야 하는 사항과 방향을 제안하였다.
