This study was to investigate if cervical vertebrae maturation stages are as useful as hand-wrist maturation stages in evaluating the mandibular growth. The subject consisted of 292 girls aged from 8 to 16 years with normal occlusion. They were classified according to diagnosis by using studycast. lateral cephalogram, and handwrist X-ray film. The results were as follow: 1. Cervical vertebrae and hand-wrist maturation stages increased with age. 2. All mandibular measurements (Ar-Go, Go-Me, N-Go, S-Gn, N-Me) increased linearly with cervical vertebrae maturation stages. 3. Ar-Go, Go-Me, N-Go, S-Gn increased linearly with hand-wrist maturation stages. 4. Ar-Go, Go-Me, N-Go, S-Gn increased relatively rapidly between cervical vertebrae maturation stages 3 and 4. Go-Me and S-Gn increased relatively rapidly between hand-wrist maturation stages 6 and 7. 5. Ar-Go, Go-Me, N-Go, S-Gn, N-Me had high correlations with cervical vertebrae maturation stages as well as hand-wrist maturation stages. These results suggest that cervical vertebrae maturation stages are reliable on evaluating the mandibular growth. 하악골 성장을 평가하는 데 경추골 성숙도가 수완부골 성숙도만큼 유용한가 규명하고자 본 연구를 시행하였다. 정상교합을 가진 만 8세∼만 16세 여성 292명을 연구대상으로 하여 진단석고모형,측모두부규격방사선사진,그리고 수완부방사선사진을 이용하여 경추 및 수완부의 골성숙도를 비교하여 다음과 같은 결과를 얻었다. 1. 연령 증가에 따라 경추 및 수완부의 골성숙도가 일정하게 증가하였다. 2. 경추골 성숙도가 증가할수록 Ar-Go,Go-Me,N-Go,S-Gn,N-Me이 일정하게 증가하였다. 3. 수완부골 성숙도가 증가할수록 Ar-Go,Go-Me,N-Go,S-Gn이 일정하게 증가 하였다. 4. 경추골 성숙도 3단계와 4단계 사이에서 Ar-Go,Go-Me,N-Go,S-Gn이 크게 증가하였고,수완부골 성숙도 6단계와 7단계 사이에서 Go-Me,S-Gn이 크게 증가 하였다. 5. Ar-Go,Go-Me,N→Go,S一Gn,N-Me은 경추 및 수완부 골성숙도와 각각 유의 한 상관성을 보였다. 이상의 결과는 하악골 성장을 평가하는 데에 경추골 성숙도가 수완부골 성숙도처럼 유용하게 사용될 수 있음을 시사한다.

Serum leptin, glucose, lipid profiles (free fatty acid, triglyceride, total cholesterol) were determined in two groups of subjects undergoing long and short strenous cycle race, 8 men who fasted overnight and then pedaled 20km cycle race and 8 men, 150km cycle race, respectively, Blood samples were collected before race, immediately after cessation of race and 2hr, 6hr after the end of race period. Cyclist pedaling 20km cycle race and cyclist pedaling 150km cycle race showed no statistical differences in leptin level. After 6hr of rest, leptin concentrations were gradually decreased but showed no statistical different in both groups. Epinephrine (p〈.01) and norepinephrine (p〈.001) concentration in comparison to pre-race levels were increased significantly. But insulin concentration in comparison to pre-race levels were decreased significantly (p〈.001). Glucose (p〈.01), free fatty acid (p〈.001), cholesterol (p〈.001) and triglyceride (p〈.01) were increased immediately after cessation of race in both groups.

Background : Enterococci are important cause of nosocomial infections. Recently, vancomycin-resistant enterococci (VRE) has been increasingly reported as significant nosocomial pathogens. Therefore, accurate identification of enterococcal species is a prerequisite step for the appropriate antibiotic treatment and epidemiologic surveillance. We wanted to know the usefulness of PCR method compared with Vitek automatic identification system. Methods : Totally 105 isolates were identified on the species level by Vitek (GPI card and software version R06.1), methyl-α -D-glucopyranoside test, and PCR methods. Results : Among 105 enterococcal isolates, 59 were identified as E. faecium, 11 E. faecalis, 6 E. gallinarum by Vitek. But 29 isolates (28%) were unidentified. Subsequently all of these isolates were analyzed by PCR, the results of which were as follows : 17 E. faecium, 5 E. casseliflavus, 7 E. gallinarum. Two isolates identified as E. gallinarum by Vitek were reidentified as E. casseliflavus by PCR and other methods far phenotypic characterization. Conclusoin : PCR method was more accurate and sensitive than Vitek for the identification of enterococci species. (Korean J Infect Dis 33:123∼127, 2001)

These bays, the Modern Art has the correlated formative elements which can't be divided into categories. The Pop Art, which became the center of the modern Art after the Second World War having the similar artistic correlations with Funk, Super Object Ceramics. These two kinds of art changed many sociocultural situations into art through the formative form called object. These Objects showed not a superficial imitation but recent actual reality which was deprived the identification. The Pop Art and the Realistic Ceramics presented the warnings against the tradition, system, material and human of the society in which it is formed and accepted, and they also represented the vision of a new life. Especially, What the interest of Realistic Ceramics is the socialization of the Modern Art. Finally. The Realistic Ceramics interrelationship : art has an effect on a society and vice versa. This research shows that the Realistic Ceramics is the new form of the Modern Art which expresses today's social reality.

일제기 지방행정의 특성에 관한 연구 : 사회 및 복지행정을 중심으로 Social and Welfare Policy

It is intended in this study to find out the factors that had arrested the development of the Korean local autonomy during the Japanese colonial period. The results of the analysis of the Japanese colonial policies in Korea explain us the process of the breakdown of the traditional local communities which had been the local autonomy units. The serial reorganization of the local administration area and its governning structure had deprived the inhabitants of the local community identity and the positive participation. The Japanese Registration Project of Landownership had made the rural communities fall in destitution. The destitution had been the strong rural pushing factor and had resulted in collapse of the entity of local communities. The Japanese colonial social welfare policy for the destitute had weakened the inhabitants of their traditional emotional community interdependancy. All of these are the factors that had arrested the development of the local self governning system in Korea.

휴전선 인접 마을의 새마을운동 사례를 통해 본 1970년대 한국 농촌사회 정치·경제적 변화 : 강원도 철원군 사곡2리와 군탄1리를 중심으로

김수경,최은봉 이화여자대학교 2005 사회과학연구논총 Vol.14 No.-

이 논문은 1970년대 권위주의 유신체제 하에서 농촌근대화를 목적으로 추진되었던 새마을운동이 한국 농촌사회에 어떠한 정치적·경제적 변화를 초래하였는지 살펴보는 것을 목적으로 한다. 실증적인연구제시를 위해 강원도 철원군 근남면 사곡2리와 갈말면 군탄1리 두 마을의 새마을운동을 사례로 분석하였다. 이 사례연구는 한수이남에 집중되어 있던 기존 새마을운동 연구의 공간적 범위를 휴전선인접지역까지 확장시켰다. 1970년대 당시 두 마을 새마을지도자들과의 인터뷰 자료와 현재 마을회관에 남아 있는 새마을운동사업 기록을 토대로 마을간 사업추진 방식과 두 마을 주민들의 참여태도, 사업성과 둥을 분석하였다. 철원군 근남면 사곡2리와 갈말면 군탄1리의 새마을운동 전개양상은 마을의 입지조건 및 마을 구성원의 차이에 따라 상이한 결과로 나타났다. 사례연구의 케이스가 협소하긴 하지만, 이 연구를 통해서 새마을운동이 직 ·간접적으로 농촌사회에 가져온 변화를 찾을 수 있었다. 새마을운동은 마을 단위로 진행되었기 때문에 동일 지역에서도 마을구성의 상이한 조건적 차이로 인해 새마을운동의 결과도 다르게 나타났다. The objective of this thesis is to see political and economic changes in Korean rural society in 1970s when Saemaul Undong(Movement) was launched by authoritarian government for the modernization in an agricultural district. This paper focuses on Saemaul Undong in two villages of Cheorwon, Kangwon Province or Sagok2-ri and Cuntanl-ri in order to provide actual evidence. Based on the interviews of two towns' then Saemaul Leaders and the information on Saemaul Undong of those areas during the 1970s, this research analyzes people's attitudes, the way of the Movement and the achievement of the Movement. In addition, this paper emphasizes on some changes in political and economic areas of the two villages for about 8 years, comparing to before and after the movement being implemented. They have similarities as well as differences in the stages of Saemaul Undong. firstly, it led the dwellers to actvely participate in the process. Secondly, the residents could express their opinion to the government through the town meefngs. Thirdly, newly-elected leaders, called Saemaul Undong leaders were main actors who are at the center of the course. Although they took the helm just within the Saemaul Undong project, their capacities resulted in various consequences of the Movement under the autonomy of the town unit. Apart from other changes, it altered the appearances of the rural communities. It came to build new roads, convert old houses to modernized ones. It is difficult to say that Saemaul Undong has drawn the actual increase in the economic incomes. However, development in the repairing facilities in it played a key role in going up in the crop productivity, Therefore, it is fair to say that Saemaul Undong had a positive effect on the agricultural economy to some extent.
