This study was conducted to investigate the efficacy of larval stages of three species, namely, Tenebrio molitor, Protaetia brevitarsis seulensis, and Ptecticus tenebrifer larvae, in degrading poultry manure, specially, broiler and duck manure. The survival rates of larvae were also noted. For the experiment, T. molitor (n=300), P. brevitarsis seulensis (n=60), and P. tenebrifer (n=300) hatched larvae were randomly divided into six groups with three replicates. The degaradation efficacy tests were then performed for 30 days in a laboratory. The test groups were as follows: T1, 110 g broiler manure + T. molitor larvae (n=50); T2, 110 g duck manure + T. molitor larvae (n=50); T3, 125 g broiler manure + P. brevitarsis seulensis larvae (n=10); T4, 125 g duck manure + P. brevitarsis seulensis larvae (n=10); T5, 105 g broiler manure + P. tenebrifer larvae (n=50); and T6, 105 g duck manure + P. tenebrifer larvae (n=50). The groups showed significant efficacy in degrading broiler and duck manure (p<0.05). The highest survival rates were recorded for T. molitor larvae in both manure types [T1 (92.67%) and T2 (50%)], followed by P. brevitarsis seulensis larvae (T4, 40%) and P. tenebrifer larvae (T6, 14.67%) in duck manure. Next, the survival rates of P. brevitarsis seulensis (T3) and Ptecticus tenebrifer larvae (T5) in broiler manure were 0%. In conclusion, these results point to the feasibility of using insect larvae to degrade broiler and duck manure.

본 연구는 솔잎 토착미생물을 이용하여 제조된 발효사료 급여가 돼지의 성장, 혈액성상, 도체형질 및 경제성에 미치는 영향을 규명하고자 실시하였다. 평균 체중 75kg인 3원교잡종 (Landrance${\times}$Yorkshire${\times}$Duroc) 180두를 공시하여 돈방 당 15두씩 시험구당 3반복으로 실시하였다. 발효사료는 원료 사료와 미생물을 혼합 후 혐기적 상태로 10일간 발효시켰으며, 양돈용 사료에 0 (대조구, CON), 3 (T1), 5 (T2) 및 10% (T3)로 대체하여, 42일간 급여 후 도축하였다. 발효사료의 조단백질 함량은 발효 후가 발효 전보다 높았지만 (p<0.05), 조섬유 함량과 pH는 낮았다 (p<0.05). 돼지의 혈중 Hemoglobin 함량은 T3구가 대조구에 비해 높았고 (p<0.05), Hematocrit 함량은 대조구와 T1구가 T2구와 T3구에 비해 높았고 (p<0.05), Platelet 함량은 T1구가 T2구와 T3구에 비해 높았다 (p<0.05). 대조구의 혈중 total cholesterol, LDL-cholesterol 및 Triglycerides 함량은 발효사료를 대체한 모든 시험구에 비해 높았으나 (p<0.05), HDL-cholesterol 함량은 적었다 (p<0.05). 지육중량과 지육율은 T1구와 T3구가 대조구와 T2구에 비해 높았으며 (p<0.05), 등지방 두께는 T1구와 T2구가 T3구에서 비해 낮았다 (p<0.05). 육 등급은 발효사료를 대체한 모든 시험구가 대조구에 비해 개선되었으며 (p<0.05), kg 증체당 사료비는 발효사료를 급여했을 때 약 2-6% 적었다. 따라서 솔잎 토착미생물을 이용하여 제조한 발효사료의 급여는 돼지의 건강과 육 등급 개선 및 사료비 절감에 도움이 될 것으로 사료된다.

This study was conducted to investigate whether exercise therapy applied in an efficacy expectation promoting program based on the self-efficacy theory of Bandura(1977) would increase self-efficacy and metabolism in NIDDM patients. The study design was a nonequivalent control group pre-test post-test quasi-experimental desist The exercise therapy applied in the efficacy expectation promoting program was composed of a staged exercise program, a small booklet relating personal experience with diabetes mellitus and a telephone coaching program on performance accomplishment. vicarious experience and verbal persuasion, which are all induction modes of efficacy expectation. The subjects of the study were twenty eight NIDDM patients who received follow-up care regularly through the out-patient department of endocrine medicine in one general hospital which had a diabetic clinic. Fourteen were assigned to the experimental group and fourteen to the control group. The experimental group participated in the exercise therapy applied in the efficacy expectation promoting program from three to five times per week for four weeks and the control group did not have the program. The collected data were analyzed using the X²-test, t-test, paired t-test, and Cronbach's Alpha using SPSS /PC/sup +/. The results are summarized as follows 1. Experimental group had higher efficacy score than control group(t=5.98, p=.00). And. There was a significant different in the efficacy score before exercise therapy applied in the efficacy expectation promoting program and after in experimental group(t=-6.42, p=.00). 2. Experimental group did not have lower level of glucose metabolism than control group(FBS : t=.32, p=.75, HbAlC : t=.60, p=.55, pc 2hrs. glucose : t=-.29, p=.78). But, There was a significant different in the aunt of glucose metabolism before exercise therapy applied in the efficacy expectation promoting program and after in experimental group(FBS : t=3.63, p=.003, HbAlC t=4.20, p=.00, pc 2hrs. glucose : t=1.93, p=.001). 3. Levels of lipid metabolism were partly a significant different between Experimental group and control group(triglyceride t=-1.87, p=.07, HDL cholesterol : t=-.29, p=.77. body weight : t=1.78, p=.09, Total cholesterol : t=-2.17, p=.04). And, There was partly a significant different in the amount of lipid metabolism before exercise therapy applied in the efficacy expectation promoting program and after in experimental group(triglyceride : t=2.50, p=.03, HDL cholesterol : t=-.43, p=.67, body weight : t=5.34. p=.00, Total cholesterol : t=2.26, p=.04). In conclusion, it was found that exercise therapy applied in an efficacy expectation promoting program was an effective nursing intervention for increasing self-efficacy and metabolism.

The author compared indices of thyroid function in 76 patients with panic attack and 80 control subjects. And SCL-90-R was performed to evaluate the relationship between the psychiatric symptoms and thyroid indices in the patients with panic attack The results were as follows: 1). No siginificant differences in T3, T4 or TSH were found between the two groups. But T3 level was significantly lower in male panic patients than male controls(p<0.005). 2) The T3 level was significantly lower in male panic patients who had higher depression socre than average in SCL-90-R(p<0.025). 3) The TSH level was significantly lower in patients with higher anxiety(p<0.001) and phobia(p<0.05) score and in female panic patients(p<0.001) with higher anxiety and phobia score than average in SCL-90-R. 4) The phobic symptom(p<0.001) was siginificantly higher and the T3 level(p<0.005) was lower in the male than the female patients with panic attack.

Topex/Poseidon(T/P)고도계 자료를 조석 수치 모델에 혼합하여 북동 아시아 해역의 $M_2,\;S_2,\; K_1$, 및 $O_1$ 분조를 $5'{\times}5'$ 분해능으로 계산하여, 북동 아시아의 조석을 산정하였다. Blending 방법에 사용되는 가중 인자 값에 대한 모델반응을 검토하기 위해 $M_2$ 분조만을 고려한 수치 실험이 수행되었으며, 수치 실험을 통해 T/P 자료를 정확히 재현하되 혼합함으로써 발생하는 잡음을 줄이기 위해 가중 인자 값은 수심의 평방근에 반비례하도록 설정하였다. T/P자료에서 구한 $M_2,\;S_2,\; K_1$, 및 $O_1$ 분조를 동시에 혼합한 수치 모델 결과는 연구 해역 내의 모든 T/P궤도 자료와 비교되었다. 진폭 오차와 지각 오차의 평균은 거의 0으로 나타났다. 진폭 오차의 표준 편차는 2 cm 내외였으며, 지각오차의 표준 편차는 $10^{\circ}$보다 작았다. T/P자료를 혼합한 모델 결과는 특히 얕은 수심(h<250m)의 T/P 궤도 자료와 거의 일치하는 것으로 나타났다. 그러나 T/P 자료만으로부터 계산된 진폭과 지각은 깊은 수심 해역에 대해서는 불합리한 공간 변화를 보이는 반면, 이들 자료를 동화시킨 모델 결과는 T/P 자료와는 차이를 보이나 합리적인 진폭과 지각의 공간 분포를 보였다. 한편 T/P자료를 혼합한 모델 결과는 자료 동화에 사용하지 않은 연안 관측 자료와도 비교적 잘 일치하였다.

Purpose: This study intends to investigate gender role identity and egalitarianism consciousness among adolescents and to determine the relationship between the two factors. Method: Data were collected from 376 middle and high school students in U City. Tools used were the Korean Sexual Role Identity (Kim, J. H., 2005) and the Gender Egalitarianism Consciousness among Adolescents (Kim, 2002). Data were analyzed using SPSS 12.0 for t-test, one-way ANOVA and Pearson correlation coefficient. Results: There was no significant difference between boys and girls in sender role identity. Boys' gender role identity was different according to school grade (t=-3.19, p= .00), frequency of mother's hugging (t=-2.28, p= .02) and girls' according to religion (t=-2.24, p= .03) mother's job (F=3.59, p= .02), father's education level (F=3.20, p= .04), mother's education level (F=3.24, p= .04), family harmony (F=7.28, p= .00), and frequency of mother's hugging (t=-2.41. p= .02). There was significant difference in egalitarianism consciousness according to sender (t=-12.70. p= .00) Boys' egalitarianism consciousness was different according to school type (t= .02, p= .00) and father's education level (F=4.97, p= .02), and girls' according to school grade (t=-4.21 p= .00), school type (t=-3.12, p= .00), father's level of education (F=3.78. p= .02), decision maker of important domestic matter (F=4.95, p= .00) and frequency of mother's hugging (t=2.53, p= .01). In Girls, sexual role identity and sender egalitarianism consciousness were significantly correlated with each other (r= .01, p= .04). Conclusion: Through the study, it was found that boys' concern for sexual equality of was remarkably lower than girls. Therefore, it is necessary to offer curriculums for boys and to start social education for parents.
