목적: 작업관련 근골격계질환은 중요한 직업관련성 질환 중의 하나이고 작업관련 수근관증후군은 이러한 작업관련 근골격계질환 중에서도 많은 부분을 차지한다. 이 연구는 작업관련 수근관증후군의 역학적 특성에 대해 알아보고자 수행되었다. 방법: 본 연구에서는 '수근관증후군 감시체계'를 통해 2000년 6월부터 2003년 2월까지 보고 된 672례의 수근관증후군 사례를 분석하였다. 직업력이 확인된 314명을 대상으로는 직업 및 작업내용에 따라 작업관련성 수근관증후군의 비율이 어떻게 달라지는지를 분석함으로써 수근관증후군 위험요인을 조사하였다. 결과: 직업력이 확인된 314명의 환자 중 작업 관련성이 의심되는 사람은 228명 (72.6%) 이었다. 직업별로는 '단순노무종사자', '농림어업숙련자', '서비스종사자' 등에서 작업관련 수근관증후군의 비율이 여성에서 유의하게 높게 나타났으나 연령, 비만도 지수, 과거병력 등에 따른 차이는 관찰되지 않았다. 주관적 증상 중에 '손을 많이 사용한 후 심해진다'와 '손을 털면 덜해진다'라는 항목을 작업관련성 수근관증후군 환자에서 더 많이 호소하였고 다른 증상은 별다른 차이를 보이지 않았다. 작업관련성 수근관증후군 환자가 비교적 많이 노출되는 작업은 '지나치게 손을 뻗쳐서 하는 일', '손을 불편한자세로 유지하는 일' 등이었다. 결론: 전체 수근관증후군 중 작업관련성이 있다는 비율이 매우 높은 것을 확인할 수 있었다. 수근관증후군 감시체계가 작업관련성 수근관증후군의 여러 특성을 밝히는데 매우 효과적인 것으로 나타났으나 현재까지는 중재 대상을 구체적으로 특정하기에는 한계가 있다. Objectives: Carpal tunnel syndrome (CTS) is one of the most important work related musculo-skeletal diseases in Korea. However, there are few epidemiologic studies on the work-related CTS (WR-CTS). This study aimed to investigate the epidemiologic characteristics of WR-CTS in Korea. Methods: Data obtained from the "CTS Surveillance System". Physician case-reports in the surveillance were used to document patterns of WR-CTS by age, gender, occupation, sign, symptom, working history. Results: Six hundred and seventy-two cases of WR-CTS were ascertained of which 3 14 with complete information on occupational history were analyzed. It has been estimated that as many as 72% of' all CTS cases are work-related. The highest proportion of WR-CTS was observed in 'elementary occupation workers', followed by 'skilled agricultural, forestry and fishery worker'. The distributions of WR-CTS cases were similar with respect to age, obesity, and past medical history. The proportion of WR-CTS was higher in females. There was no significant difference in physical examination findings between WR-CTS and non WR-CTS cases. Repetitive work and the inappropriate hand posture seemed to be the risks for WR-CTS. Conclusion: WR-CTS is a significant public health problem. The CTS surveillance system is quite useful to elucidate the characteristics of WR-CTS, but it remains of limited use in targeting specific industries and occupations for intervention.

A Corpus-based Study of the Truth-related Words in Korean Used as Discourse Markers. Kim, Taeho & Jeong, Seon-yeong . 2012. Studies in Cross-cultural studies. This study investigates how the truth-related words in Korean, which were originally noun or adverb with ``truth`` related meaning, can be used as discourse markers with the functions such as ``emphatic marker``, ``attention getter``, or ``hesitation marker``, and it argues that such functions of the discourse markers are the result of grammaticalization process. That is to say that the truth-related words have acquired new functions as discourse markers from their corresponding lexical items as a noun or an adverb through grammaticalization process. In this study, we demonstrate that the truth-related words tend to appear sentence-initially or sentence-medially when they are used as discourse markers. We also show that they are most likely to be used as emphatic marker because of the lexical meaning of the truth-related words. Finally, we state that truth-related words differ from one another in where they appear and what function they are used with.

1960년대 미국 흑인 정치 상황과 랭스턴 휴즈의 시

정호선 신한영미어문학회 1998 새한영어영문학 Vol.40 No.-

Ask Your Mama and The Panther and the Lash illustrate the two tendencies in Hughes's ideas during the 1960's - toward an affirmation of black soul, and toward a view of the Negro as properly a part of an interracial America. Hughes found it difficult to resolve the political implications of these two perspectives. Integration is impossible, he believed, because white people will not accept Afro-Americans. However he thought separatism also impossible, because the black community is weak and the black bourgeoisie unreliable. And Hughes found separatism undesirable, for his ultimate goals were racial harmony and brotherhood. These contradictions led Hughes to a third alternative, a radical answer. But the radical poems collected in The Panther and the Lash, with their emphasis on antiimperialism and third world liberation, fail to provide any guidance to Afro-Americans beyond inspiring them with a diffuse feeling of militance and resistance. Should the Negro look for allies among the white workers? Should he support black business or a black political party? How is he to break out of the cycle of poverty? Hughes really didn't know. Because of the emotional conflict between his attraction toward blackness and the Negro masses on the one hand, and his belief in the possibility and desirability of integration on the other, Hughes was at his best when exposing black's problems rather than offering solutions. The parts of Ask Your Mama which voice poignantly the rootlessness of the Negro, or the angry protest poems of The Panther and the Lash, express Hughes's indignation and love for his people without confronting the difficult question, “What should be done?”

As result of computing the speed just before jump, it was 22.6 m/s in the vacuum, 21.6 m/s in the groundfriction, 20.2 m/s in the air resistance and ground friction, in application of the dynamic theory. The difference of the speed, if little, was 1.0-2.4 m/s and the frying distance was 6.6-30 m through compuer simulation. In the step of jump, the vertical speed of jumper was found to be "V_t = 2h/t" by using the model of spring, the frying distance, in the case of "t = 0.12s" (i. e. the flying elevation of 5), was 25m longer, than in 't = 0.21s', and in order to increase the effect of jump. The result of simulation on four kinds of model poses in Fig-5 proved that the pose of d type is the most efficient.

정송란,최남기,양규호,김선미,송호준 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.3

컴포머(compomer) 충전물이 파절될 경우 즉, 컴포머 수복이 실패했을 때 기존 컴포머의 파절된 부분(aged compomer)을 복합레진으로 수복해야 하는 경우를 고려해야 한다. 본 연구에서는 컴포머의 표면처리 방법에 따른 수리(repair)를 위한 복합레진과의 전단결합강도 변화를 알아보기 위해 두 개의 mold를 만들어서 Dyract AP, F2000를 컴포머 수복재료로, Z250을 수리용 복합레진 재료로 사용하여 컴포머와 레진을 부착시킨 시편을 제작하였다. 컴포머와 복합레진의 종류 조합, 본딩레진 사용유무, 열순환 처리 유무, 표면거칠기 부여 유무, 기존 수복물의 시효(aging)에 따라 10개의 군으로 나누어, 컴포머와 복합레진간의 전단결합강도를 측정하고 그 파절양상을 관찰하여 다음과 같은 결과를 얻었다. 1. 컴포머의 복합레진에 대한 전단결합강도를 측정한 결과, Dyract AP가 F2000 보다는 높은 전단강도 값을 보였으나 통계적으로 유의한 차이는 없었으며 (p>0.05), fresh 컴포머군이 aged 컴포머군보다 결합강도가 높았다(p<0.05). 2. 각 군간의 전단결합강도를 측정한 결과 Dyract AP에 접착제를 도포하고 Z250을 접착시킨 제 5군이 가장 높았으며, Dyract AP를 충전하고 1주일간 물에 보관한 후 건조시켜 표면을 roughening 한 후 Z250을 충전시킨 제 9군에서 가장 낮았다(p<0.05). 3. 열순환을 시행한 군이 시행하지 않은 군보다 전단결합강도가 낮게 나타났으나 통계적으로 유의한 차이는 없었다. 4. 각 재료들의 결합실패가 일어난 파절단면을 조직학적으로 관찰한 결과, 전반적으로 접착파괴를 보였으나, 접착제를 도포한 군에서는 응집파괴가 우세하게 나타났다. 이상의 결과 fresh 컴포머 위에 접착제를 도포한 다음 수리용 복합레진 재료를 사용함으로써 컴포머와 복합레진간의 결합력을 증가시킬 수 있음을 알 수 있었다. 그리고 fresh 컴포머 위에 복합레진을 즉시 충전한 경우가 높은 결합력을 얻을 수 있었다. Aged 컴포머와 복합레진간의 성공적인 결합력을 얻으려면 aged 컴포머의 표면을 mechanically roughening하고 접착제를 도포한후 복합레진을 충전해야 할 것으로 사료된다. For the purpose of comparing the bond strengths of compomers to composite resin, composite 2250, and two polyacid modified composite resin, Dyract AP and F2000, were selected and investigated using universal testing machine for measuring the shear bond strengths. Additionally, the failure modes were examined by observing the fractured surfaces of each specimen. The following results were obtained. 1. The shear bond strength of Dyract AP to Z250 were higher than those of F2000, but there was no statistically significant difference between group 1 and group 3(p>0.05), and groups using fresh compomers showed higher bond strength than those using aged compomers(p<0.05). 2. After measuring the shear bond strength of each group, it was highest in group 5 and was lowest in group 9(p<0.05). 3. Although there was no statistically significant difference, groups treated with thermocycling showed lower bond strengths than those of non-thermocycling groups. 4. Overall compomer/composite resin failures were adhesive. Cohesive failures occurred mainly in groups using bonding agent. Based on these results, the application of a bonding agent on fresh polyacid-modified resin composite increases the bond strength between polyacid-modified resin composite and composite resin. Additionally, the surface of aged polyacid-modified resin composite has to be roughened mechanically and a bonding agent has to be used in combination with composite resin.
