Preformed stainless steel crown is an useful restorative material for the treatment of badly broken down primary teeth. However iatrogenic damage to adjacent teeth might occur during the process of tooth reduction. Such damages might lead to plaque accumulation and increase the risks of caries initiation. Especially the damage can make a problem in the first permanent molar. Purpose of this study was to investigate an iatrogenic damage to the first permanent molar during preparation of second primary molar for preformed stainless steel crown. Twelve children restored with preformed stainless steel crown to second primary molar were selected. Contact areas were separated with separation elastics, and tooth surfaces were cleaned. After taking negative impression using vinylpolysiloxane impression material, the specimens were examined by scanning electron microscope for the detection of iatrogenic damage. The prevalence of iatrogenic damage was 66.7% and variable appearances and So we can suggest that when preparing teeth for preformed stainless steel crown, we should be careful about adjacent teeth not to make an iatrogenic damage.

Under representative democracy, members of the National Assembly exercise their authority to propose, enact, and revise bills on behalf of the people, and the legislation of such lawmakers has a great impact on individuals and society. There exist criticisms that the quality of legislator-sponsored bills has not improved while the number of them has been expanding recently. This study examines the type, productivity, and efficiency of legislation in the 17~19th National Assembly, and empirical analysis is conducted on how the lawmaker's legislations respond to election-related variables such as voter turnout and election competition. The results show that legislator-sponsored bills are mainly produced in the area of governance, finance, macroeconomic policy, social welfare, and health. The number of legislator's proposals increases, while the passing rate decreases, and the processing period extends. Constituents' participation in voting has been shown to enhance legislative efficiency. Based on the results, the paper emphasizes the enhancement of transparency in the legislative process, the improvement of the people's political knowledge, and the revitalization of election functions for the improvement of parliamentary legislation.

I investigated whether network structure of legislators affects legislative performance in a cosponsorship network. I presented the theoretical basis with network closure and structural holes, and analyzed the network in the 19th National Assembly of Republic of Korea. In the directed and weighted network, each tie means that cosponsors support the bill sponsors proposed. The performance was measured by the number of initiatives and the ratio of reflected legislation, and the network structure was measured by size, density, hierarchy, and constraint. I found that the legislators with brokerage structure have a lot of initiatives in making connection with many legislators in various groups and the legislators with hierarchical structure have the higher ratio of reflected legislation with the continuous and strong support from the members of their group. I also found that the network of ruling party lawmaker is more hierarchical than the network of opposition lawmaker.

Gingival recession could occur after orthodontic or endodontic treatment. This could influence not only functional and aesthetic problem, but also patient's treatment satisfaction. There are a lot of techniques for preventing gingival recession, but laterally positioned flap with subepithelial connective tissue graft could get definite advantages such as increase of keratinized gingival width and harmonious color match between graft tissue and surrounding tissue. Clinician should select a right patient case and diagnosis with clinical and radiography exam. In a surgical procedure, getting enough amounts of subepithelial connective tissue and flap coverage should be taken into consideration. The clinical outcomes in this case report shows laterally positioned flap with subepithelial connective tissue graft could be a treatment with predictive outcome.

이글은 대의민주주의에서의 입법 메커니즘에 대한 이론적 논의를 전개한다. 이러한 논의를 근거로 한국 국회의원의 입법생산성에 영향을 미치는 변수들을 도출하고, 이 변수들이 16대와 17대 국회의 입법생산성에 미치는 효과를 분석한다. 이글의 경험분석은 국회의원의 입법생산성은 이들의 학력, 법조경력, 관직경력, 의정경력 같은 개인적 배경과 서로 무관하다는 사실을 보여준다. 이글의 경험분석에 의하면, 국회의원들의 개인배경보다는 원내 정당간의 역학관계와 소속정당의 여당지위, 그리고 의회요인들이 국회의원들의 입법생산성에 영향을 미치는 것으로 밝혀졌다. 이러한 분석결과는 한국 대의민주주의의 작동과 관련된 함의를 제공한다. 국회의원의 입법활동에 대한 정보를 접하기 어려운 환경에서는 국회의원의 개인배경에 의존하는 국회충원 방식이 대리인문제를 유발할 가능성이 높다. 이글은 국회의원 입법활동에서 발견되는 대리인 문제의 해소를 위한 제도적 방안들에 대해 논의한다.

본 연구는 할당제를 통해 정계에 진입한 비례대표 여성의원들과 맑은넷 출신 여성의원들이 여성계를 위해 어떤 법률안을 얼마나 많이 발의하였는가 하는 문제의식에서 출발하였다. 여성단체가 할당제와 맑은넷 운동을 벌인 이유는 여성을 가장 잘 대변할 수 있는 것은 여성이라는 논리가 내재해있었기 때문이다. 16, 17대 국회에서 여성의원에 의해 대표발의된 법률안을 분석대상으로 한 본 연구는 여성의원이 증가함에 따라 여성관련 법률안이 증가하였는지 살펴 보았고, 어떤 내용의 입법안을 발의하였는가 분석하였다. 이같은 분석을 통해 여성의원의 대표발의 활동에 있어서 여성의원간에 어떤 차이가 나타났으며, 궁극적으로 할당제를 채택한 것이 효과가 있었는가 하는 것을 분석하였다.

Physiologic tooth attrition is accepted as a natural change. But when pathologic changes, such as loss of occlusal vertical dimension, masticatory pain, loss of masticatory function, and loss of esthetics occur, restorative measures should be taken by dentist. A patient visited the clinic with the chief complaint of 'My lower teeth bite the palate and it hurts'. It was diagnosed as iatrogenic attrition of lower natural dentition caused by inappropriate upper restorations, resulting in traumatic overbite. Through model analysis and diagnostic wax up, increase in vertical dimension was decided. Upper and lower dentitions were restored with new prostheses. After restoration, satisfactory outcomes were achieved both in functional and esthetic aspects.

The purpose of this study is to verify that voting behavior of congressmen can vary depending on the different candidate selection methods of political parties. Specifically, this paper examines whether congressmen elected through a primary tend to deviate from the party line vote in the floor voting, compared to those who did not. As a result, it was founded that congressmen who went through competition of the primary are more likely to defect from the party line vote than who did not. This empirical evidence suggests that if the introduction of the open primary system is further expanded in the future, it may lead to weakening of party cohesion and reinforcing lawmakers' autonomy.
