흰쥐 편도체에서 칼슘결합단백인 calbindin-D28K함유 신경세포의 생후 발달에 관한 면역조직학적 연구
정윤영,김종중,문정석,박영란,정상봉,김현곤,박상수 조선대학교 2001 The Medical Journal of Chosun University Vol.26 No.1
Background and Objectives : The calcium-binding protein, calbindin-D28K(CB) is widely distribution of CB in rat amygdala during postnatal maturation, in order to provide an insight into the developmental role it may play in the amygdaloid neurons. Materials and Methods : The present study is based on 28 postnatal cases ranging from the day of birth, postnatal day 0 (P0) to 30 days (P5, P10, P15, P20, P30), and these cases were compared with adult rat amygdala. Cryostat sections processed free-floating with monoclonal antibody by immunohistochemistry. Results : CB-immunoreactive neurons were already found at birth in all amygdaloid nuclei except the intercalated nucleus. The intensity and number of immunoreactivity of CB-containing neurons increased during the first 10 days of postnatal life but dramatically decreased at P15. Mature patterns of CB-immunoreactive neurons were achieved at P20. In the adult amygdala, CB-immunoreactive neurons were distributed in almost all amygdaloid nuclei except the intercalated nucleus. Conclusion : The present results show early appearance of CB immunoreactivity in the amygdala. It may be related to the early appearance of CB immunoreactivity in many other brain regions, and suggests that CB may play a functional role during the development of the nervous system including amygdala.

To contribute to promotion of health and preservation of labor power of Korean laborers, the body height and body weight were measured for 10,407 workers(6,201 male, 4,206 female) in the age group of 20-29, engaged in manufactures in the Gumi industrial complex, Gumi city, Kyungpook province. The above data were extracted from the 1985 periodic examination chart for calculation of the mean body weight, mean body height, correlation coefficient and regression equation between weight and height, standard body weight, body mass index(BMI) and distribution of laborers within Garrow's classification of BMI by age and sex group. Mean body height of 20-29 age group was 168.2±5.61 cm for male and 155.9±5.26 cm for female. Mean body weight of 20-29 age group was 61.4±6.56 kg for male and 52.4±6.00 kg for female. Correlation coefficient and regression equation of 20-29 age group were +0.541 and Y(Wt)=0.632X(Ht)-44.975 for male and +0.559 and Y(Wt)=0.637X(Ht)-46.898 for female. Standard body weight of 20-29 age group was 53.0 kg at 155 cm, 59.3 kg at 165 cm, 65.6 kg at 175 cm for male and 51.8 kg at 155 cm, 58.2 kg at 165 cm at 64.6 kg at 175 cm for female. Range of normal body weight of 20-29 age group was 47.5-58.5 kg at 155 cm, 53.8-64.8 kg at 165 cm, 60.1-72.1 kg at 175 cm for male and 46.9-56.8 kg at 155cm, 53.2-63.2 kg at 165 cm, 59.6-69.6 kg at 175 cm for female. Range of obesity of 20-29 age group was 64.1 kg and over at 155 cm, 70.3 kg and over at 165 cm, 76.7 kg and over at 175 cm for male and 61.8 kg and over at 155 cm, 68.2 kg and over at 165 cm, 74.5 kg and over at 175 cm for female. Body mass index(kg/m²) of 20-29 age group was 21.7±1.95 for male and 21.6±2.05 for female, 75.9% of male laborers and 71.3% of famale counterparts fall in the desirable range of BMI by Garrow's classification.

발전소에서 운용계획을 만들기 위해 단기의 최대부하를 예측해야 한다. 부하예측의 경우에 휴일정보나 온도경향과 같은 요인에 관해서는 불충분하고 비수량적인 정보 만을 얻을 수 있다. 그러므로 시계열모델을 이용한 부하예측이 필요하다. 본 연구에서는 기온-부하모델을 구성하여 주간변동, 계절변동을 제거하고 불규칙변동은 자기회귀모델을 이용하여 제거한다. 예측결과 3개월 평균오차는 여름의 평균오차가 약 3.5%정도 인 것을 제외하고 모든 계절에서 2%보다 적었다. 이것은 예측구간을 세분화 하므로서 예측보차를 줄일 수 있을 것으로 사료된다. To make weekly operational plan for power stations, we have to forecast short-term peak load. In case of load forecasting, we can obtin only insufficient and unnumerical information with respect to load such as holiday information and trend of temperature. Therefore the forecasting using a time series model is necessary. In this paper, construct temperature-load model and remove weekly variation, seasonal variation and unknown factors using autoregressive model. Average forecasting percentage error of 3 months is less than 2% in all season except summer. Average forecasting percentage error of summer is about 3.5%. But this will be decreased by subdividing forecasting-section

목적 : Pityrosporum ovale는 지루피부염의 발생에 중요한 역할을 하며 이 친지성 진균은ketoconazole제재에 감수성이 있다고 알려져 있다. 이에 저자들은 두피에 사용하기 편리한 2% ketoconazole 샴푸로 지루피부염을 치료하여 그 효과를 확인하고자 본 조사를 실시하였다. 대상 및 방법 : 두피의 지루피부염 환자 52명에게 소양감의 정도를 설문조사하고 피부과 의사의 육안으로 인설의 양을 검사한 후 광학현미경 고배율하에서 진균학적 검사를 실시하였다. 결과 : 지루피부염 환자의 소양감과 인설의 양은 치료전에 비해 치료 2주와 4주 모두에서 유의하게 감소하였으며(p<0.05) 이들 환자에서 실시한 Pityrosporum ovale의 평균 포자수 역시 치료전에 비해 치료 2주와 4주 모두에서 유의하게 감소하였다(p<0.05). 결론 : ketoconazole 샴푸는 지루피부염의 임상 및 진균학적인 면 모두에서 치료효과가 있는 것으로 판단되며 간접적으로나마 Pityrosporum ovale가 지루피부염의 발생에 관여한다는 사실을 알 수 있었다. It is suggested that Pityrosporum ovale may play an important role in the pathogenesis of seborrheic dermatitis and this organism is sensitive to ketoconazole compound. So the efficacy of 2% ketoconazole shampoo in the treatment of seborrheic dermatitis was tested and was calculated by mean scores of scale, itching and yeast cells. We interviewed fifty two patients with seborrheic dermatitis about the degree of itching and examined with naked eyes the scale of scalp of them. In a group of the patients, mycological study of P. ovale was also performed by direct smear with 20% KOH solution containng 1 : 1 Parker-ink^R The results were as follows : As for itching and scale of the scalp, the scores were significantly decreased at week 2 and week 4 as the duration of treatment prolonged in comparison with that of week 0. The mean yeast cell score at the two points of time was also significantly decreased in comparison with that of week 0. There was no significant difference in the response from the view of age, sex and duration of seborrheic dermatitis. It is suggested that the shampooing with ketoconazole 2% shampoo every three other days gave a good result clinically and mycologically.

The great span length of suspension bridges makes their static and dynamic behavior under the action of vertical, torsional and lateral forces an important engineering problem. The most significant vertical, torsional and lateral forces are due to wind, earthquake, symmetrical and unsymmetrical trafic loads. But the suspension bridge is greatly influenced by wind loads among bridges. And then, the analysis of a suspension bridge subjected to wind forces is needed. In this study, the engineering behavior problem for vertical, torsional and lateral free vibrations of suspension bridges is analyzed by using Ahmad M.Abdel-Gaffar's theory. By using this developed computer program, this study determines natural frequencies and mode shapes for the Nam-hae Bridge and compares with another result of the study.
