Purpose : To compare the size of the masseter and lateral pterygoid muscle between the affected and the unaffected side of the patients who have the chief complaints of the mandibular asymmetry. Materials and Methods : Twenty two patients (male: 4, female: 18, average age: 21.3 year-old) were radiographed using posterior-anterior (P-A) cephalography and computed tomography (CT). On P-A cephalography, the degree of deviation was determined by the distance from the mentum to the vertical reference line through the crista galli and the anterior nasal spine. On the scanned tracing papers of the maximum cross-sectional area of the masseter and lateral pterygoid muscle using axial CT images, the pixel number was measured. The ratio of the affected : unaffected sides were obtained. For the masseter and lateral pterygoid muscle, the relationship between the muscular volume and degree of skeletal hypoplasia was studied. Results : The half cases showed no skeletal asymmetry. The lateral pterygoid muscle of the affected side was larger significantly than unaffected side (p<0.05). However, there was no significant difference between two sides in the cases of skeletal asymmetry. There was only significant difference in the cases without skeletal asymmetry (p<0.05). Conclusions : To some extent, the slight mandibular hypoplasia could affect the growth of some masticatory muscles.

Given the magnitude of problems encountered by poverty-stricken mother-headed families and the significant impact that the families will have on their children, investigation on quality of life and specific welfare needs of the families is of an urgent need. Although previous research on the mother-headed families focused on the various aspects of living arrangement and some of the problems that those families have, most of them heavily relied on dada generated by social survey research. Using qualitative dada gathered through the grounded theory research method, this study highlights subjective meanings of quality of life perceived by the respondents and identifies subsequent social welfare needs of the target population. The result of this study shows that among the 18 respondents who participated in our research, one category of respondents perceived their current life as "lining in hell" which is expressed by the terms of hardship, misgiving, sorrow, broken-heart while the other perceived it as "self-sufficient" which is expressed by the terms of a little fortunate, satisfied, good stroke from others. The former includes persons who have server economic and health problems as well as the problems of family relationship especially with their children. however, the latter includes persons who are currently employed and have no serious health problems. Factors such as the degree to which their children's academic performance in school is acceptable and their religious beliefs are strong enough are significantly related to the positive and negative perceptions or their current life. In conclusion, economic, health, and educational needs of the poverty-stricken mother-headed families are found to be important, Welfare policy and social work services must be arranged to cope with those unment needs of the vulnerable families. Building an informal helping network as a specific intervention method of social work has been strongly recommended along with the changed role of social welfare centers in delivering services for those families. The issue of empowerment and feministic counseling have also been discussed in this article.

단백질분해효소를 생성분비하는 호알칼리성 Coryneform bacterium TU-19의 분리 및 동정

최명철,양재섭,강선철 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.2

토양으로부터 알칼리성 단백질분해효소를 생성분비하는 호알칼리성 미생물을 분리하였다. 이 균의 형태적 특징은 Gram 양성이었으며, 포자를 형성하지 않고, 운동성이 없으며, 불규칙적인 간균의 형태를 하고 있는 호기성 미생물이었다. 또한 기타 다른 형태적, 생리생화확적 특징과 종합적으로 비교해 볼 때 이 균주는 Coryneform 세균과 매우 유사하였다. 따라서 본 분리균주는 Coryneform bacterium TU-19로 잠정적으로 동정하였다. 그러나 화학적 분석 결과 및 부분적인 생리생화적 특징들에 있어서는 Coryneform bacteria의 어느 종과도 정확히 일치하지 않았다. An alkalophilic bacterium producing alkaline protease(s) was isolated from soil. It was a Gram-positive, non-sporulating, immotile, irregular rod, strictly aerobic, and weak acid-forming bacterium. The morphological, physiological, and biochemical characteristics of the isolate resembled those of the Coryneform bacteria. However, there was not any species within this genera to which microorganism can be closely matched. Therefore, it is provisionally identified as a Coryneform bacterium TU-19.

朴宣東,崔外哲 대한본초학회 2001 大韓本草學會誌 Vol.16 No.2

The purpose of this study was to research the effect of Gunggwichongsoyjungtant(芎歸蔥蔬理中湯) and its component groups on diabetes in alloxan-induced diabetic rats. Sprague-Dawley male rats weighing 200±10 gm were randomly assigned to two normal, two control and eight experimental groups. The experimental groups were classified into Gunggwichongsoyijungtant(GT group), Bogihyulyak(G-1 group), Onleeyak(G-2 group) and Balsanyigiyak(G-3 group). Diabetes was experimentally induced by abdomental injection of 100 ㎎/㎏ of body weight of alloxan. Animals were sacrificed at the 6th and 11th day of diabetic states. The results were obtained as follows: In carbohydrate metabolism, the level of glucose in control group was three-fold higher after alloxan injection than that of normal group. In GT group the level of glucose was decreased by 48% compared with that of control group, and in component groups it was decreased by 72%, 81%, and 82% respectively. In fat metabolism, the level of triglyceride in serum were lower in GT group by 74% with high significant difference and had similar tendency in components groups compared with that of control group. The levels of total cholesterol in serum were lower in GT group by 81% with significancy and had similar tendency in components groups. And the levels of HDL on serum were increased in GT group by 144% with significant difference. And in component group it had similar tendency compared with that of control group. In protein metabolism, the level of total protein and albumin were higher in GT group by 121% and 134% respectively with high significant difference, and G-1, G-2 group in component group also increased with significant difference compared with control group. In kidney function, the level of creatinine and BUN were decreased in GT group by 77% and 62% respectively with high significant difference, and other groups were lower but with no significancy compared with control group. In liver function, the level of GOT, GPT, γ-GTP, ALP and bilirubin were lower in GT group with significant difference. And in component group, it had similar tendency compared with control group. These results suggest that Gunggwichongsoyijungtant(芎歸蔥蔬理中湯) has strong effect on diabetes, so it is useful to prevent diabetes, and G-1 group had more effect on diabetes than any other groups in component groups.

In the case of the reasons they did not visit the skin care rooms, the proportion of 'no interest' was highest (36.6%). 23.2% did not visit them because they thought the fee for skin care was expensive and 19.5% did not visit them because they thought the skin care room were only for women. 7. In the variables of giving advice concerning skin care, the proportion of 'their own' was highest (29.8%). The proportion of female family members was 28.2% and the proportion of the girl friend was 27.7%. In the case of the age related to having the girl friend's advice, the proportion of 'over 25 years old' was 31.9% and the proportion of '20 years old to 24 years old' was 26.4%. The proportion of 'less than 19 years old' was 23.5%. The older they were, the more they had the girl friend's advice. 8. According to the sources of getting information on skin care, the proportion of mass media (TV, Radio etc.) was highest (36.7%). 26.0% of them obtained them through the girl friend and 13.9% obtained them through female family members. Only 8.4% got them through magazines. 9. The factors influencing the experience of visiting skin care rooms were experience of side effect of foundation cosmetics, concern about skin care, expiration date of cosmetics or checking of directions of using cosmetics, donsideration of skin character when using soap, and regular exercise for health. From above results, it can be concluded that skin care and beauty specialists working in beauty academies or the department of cosmotology at colleges or universities must make efforts to change the negative recognition of male skin care through deep and comprehensive research. It is also necessary to develop systematic education course and institutionalize the qualification management system.
