Papulonecrotic tuberculid is an eruption of necrotizing papules, particularly affecting the extremities and occurring in more or less symmetrical crops, and responding to antituberculosis therapy. Individual lesions heal with scarring. Histologically, vascular involvement is seen in early lesions. Late lesions are divided into two forms. In superficial forms, wedge shaped area of necrosis forms in epidermis and upper dermis. Epithelial and lymphoid cells gather around its periphery. In deep forms, with no epidermal change, granulomatous changes surrounded by well defined palisading histiocyte and lymphoid, epithelioid cells are seen. In mid-dermis and perivascular area, vessel shows vasculitis. In the first case, leukocytoclastic vasculitis and early granuloma formation were seen. In the second case, palisading granuloma formation was seen. In the third case, tuberculoid granuloma formation was seen. We report three cases of papulonecrotic tuberculid showing three different stages of histological finding, in individual cases.

백영석,안동현,조연규,남정현,최보율,강윤주,고복자 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.3

연구목적 : 청소년을 대상으로 장애가 있는 식이태도 및 식이행동과 관련된 요인들에서 인종과 문화적 차이가 있는가를 보는 것이다. 방 법 : 1996년도에 3129명의 중고등학교 남녀 학생을 대상으로 학교 장면에서 신체 계측과 설문지를 통하여 수집하였으며 연령은 13세부터 16세 사이의 학생들로 분포되었다. 학생들의 분포는 서울 지역의 663명, 양평 지역의 821명, 조선족이 사는 연길 지역의 830명 그리고 한족이 사는 길림 지역의 815명이었으며, 그들은 모두 키, 몸무게, 신체질량지수, 부모의 수입, 아버지의 학력, 체중조절 설문지, 신체상 척도 및 식이태도검사 등의 내용을 완성하였다. 결 과 : 신체질량지수(BMI)에서는 지역, 성별, 사회경제적 상태에 따른 차이가 없었다. 연길과 길림 지역의 학생들이 서울과 양평 지역의 학생들보다 심한 저체중과 심한 과체중을 갖는 학생들이 많았다. 연길과 길림 지역의 학생들이 서울과 양평의 학생들보다 식이태도검사(EAT-26)의 평균치가 높아 식이태도와 식이행동이 나빴다. EAT-26의 20점 이상인 식이장애의 고위험군은 연길 지역의 학생이 6.9%로 네 집단 중에서 가장 많았다. 한국의 양평지역과 서울 지역의 학생들이 신체상 척도(BIS)의 평균치가 연길 지역과 길림 지역의 학생들보다 의미있게 높았다. 즉 한국의 학생들이 중국의 학생들보다 자신의 신체에 대하여 부정적인 생각을 갖고 있었다. 체중조절 행동의 유병율은 서울 지역 학생들이 26.7%, 양평 지역 학생들이 23.2%, 연길 지역 학생들이 10.6%, 그리고 길림 지역 학생들이 4.6%이었다. 식이조절과 운동은 한국의 학생들이, 식이조절과 약물사용은 중국의 학생들이 가장 많이 하는 방법이었다. 결 론 : 본 연구를 통하여 한국과 중국에서도 식이장애가 결코 적지 않을 것이라는 사실을 확인하였고, 식이장애는 인종과 사회문화적 요인에 의해 크게 영향을 받는다는 것, 마지막으로 식이태도와 식이행동 및 그와 관련된 요인들을 통해서 네 지역간의 문화전이 상태를 확인할 수 있었다. Objectives : The goal of this research was to attempt to examine ethnic and cultural differences in factors associated with disordered eating attitudes and behaviors. Methods : Data were collected from the four groups of 3,129 high school students aged between 13 and 16 years who completed school-based survey conducted in 1996. The students (663 Korean urban, 821 Korean rural, 830 Korean-Chinese and 815 Chinese adolescents) completed an instrument which assessed weight, height, Body Mass Index(BMI), parental income, father's level of education, weight control questionnaire, Body Image Scale(BIS), and eating attitudes and behaviors using the Eating Attitude Test-26(EAT-26). Results : BMI did not vary significantly by race, sex, and socioeconomic status. There were many severely underweight and severely overweight students among Korean-Chinese and Chinese than among Korean urban and Koran rural students. The EAT-26 mean scores of Korean-Chinese and Chinese subjects were significantly higher than those of Korean urban and Korean rural subjects. The EAT-26 mean score of Korean-Chinese was the highest among the four racial groups. The prevalence of high risk EAT-26(EAT-26≥20) students of Korean-Chinese was 6.9% which was the highest among the four groups. The BIS mean scores of Korean rural and Korean urban subjects were significantly higher than those of Korean-Chinese and Chinese subjects. The Korean subjects were more dissatisfied with their body than the Chinese. The prevalences of weight control behaviors were 26.7% in Korean urban, 23.2% in Korean rural, 10.6% in Korean-Chinese, and 4.6% in Chinese subjects. Dieting and exercise were most popular for weight reducing in Korean subjects. Dieting and drug use were most popular in Chinese subjects. Conclusion : These data suggest that there must be many eating disorder patients in Korea and China, and the eating attitudes and behaviors are influenced by ethnic and cultural factors. Implications for understanding sociocultural influence on eating attitudes and behaviors and acculturation are discussed.

Crude saponin(100g) were obtained by extracting the radix(5kg) of Scrophalariae koraiensis Nakai. Crude saponin were positive in the Liebermann-Burchard test. We observed 5 sports by TLC using BuOH saturated with H_2O : ethyl acetate : water(4:1:5, upper phase) as solvent and 1% Ce(SO_4)_2 in 10% H_2SO_4 as a color former. We divided into 3 fractions by common column chromatography using BuOH saturated with H_2O : ethylacetate : water(4:1:5, upper phase) as solvent.

Angioneurotic edema is rarely seen in dental practice and manifested by acute attacks of swelling of the extremities, face, airway, or abdominal visera, occuring spontaneously and suddenly or secondary to trauma. Two types are recognized : hereditary and nonhereditary. Prophylatic therapy may be used by fresh frozen plasma or antifibrinolytic agents in hereditary type. Good supportive care for acute attacks, together with a knowledge of course of the disease, can prevent asphyxiation from airway obstruction. A case of acute angioneurotic edema of the facial area in a 19-year-old man is presented in conjunction with a review of the literature. Angioneurotic edema attacks him acutely after the extraction of the lower, right 3rd molar.

The study considered various procedures for the application of chitosan on cotton fabric, the effect of the biopolymer on the exhaustion and dyeing efficiency. The application of the polycationic biopolymer chitosan to a cotton fabric allows an increase in dye exhaustion leading to a reduction in reactive dyestuff consumption, and less dye in waste waters. Chitosan boosts dyeing efficiency.

This study was performed to evaluate the actual temperature rise on the surface of Buchanan plugger using thermocouple. The heat carrier system 'System B Heatsource'(Model 1005, Analytic Technologies, Redmond, WA, USA) and the Buchanan pluggers of F, FM, M and ML sizes are used for this study. The temperature was set to 200℃ on digital display and the power level on it was set to 10. Five thermocouples were placed in direct contact with the surface of each size of Buchanan's pluggers at 1 mm increments from the tip to the 4 mm length of shank. The heat control spring was touched for 5 seconds, and temperature rise on the surface of the pluggers were measured at 1 sec intervals for more than 5 seconds with an accuracy of 0.01 using Data Logger. The data were statistically analyzed by one-way ANOVA. The results were as follows. 1. The position at which the temperature peaked was approximately at 1~2 mm far from the tip of Buchanan plugger (p<0.01). 2. The peak temperature was 215.25±2.28℃ in F plugger, 185.94±2.19℃ in FM plugger, 169.51±9.12℃ in M plugger, and 160.79±1.27℃ in ML plugger and the peak temperature was highest in F plugger and followed by, in descending order, FM plugger, M plugger. ML plugger showed the lowest peak temperature (p<0.01). 3. The temperature on the pluggers was decreased with the increase of touching time. This results suggest that the actual temperature on the surface of the pluggers dose not correlate well with the temperature set on digital display. Heat concentrates around the up. The larger plugger reveals lower temperature rise relatively.

This paper studies the schemes to apply the Simulated Annealing algorithm that is used as an optimization stchnique for neural Network as a technique for finding the optimal design of experiments and compares this implemented results with those of Branch and Bound algorithm which completely gurarantees the optimality in order to evaluate their performance. In this comparison, D-optimality is used as a criterion for optimization.

A basic fluidelastic excitation mechanism causes large whirling vibrations of tubes in model arrays when the flow velocity exceeds a critical value. The nondimensional critical velocity is ?? where ?? the threshold instability constant is a function of the tube pattern and spacing. In this paper, ?? were given that were obtained from experiment on single-row tube array in uniform crossflow. The vibration characteristics of tube array were described as a function of flow velocity.
