It is reported that the causes of unaesthetic proportion of anterior teeth vary widely. Especially, when the unaesthetic tooth proportion of the mandibular incisors arises due to the wear of the anterior teeth accompanied by the compensation of the alveolar bone, it may cause serious functional and aesthetic problems. In such case, it should be considered that the evaluation of vertical dimension and tooth proportion as well as smile line, soft tissue and hard tissue morphology. And, increase of vertical dimension or clinical crown lengthening followed by prosthodontic restorations is needed to improve the interdental mesial/distal, width/length ratio considering the anterior guidance. This case report demonstrates functional and aesthetic improvements through systematic diagnosis and treatment procedures in a 48-year-old male patient with unaesthetic anterior teeth proportion because of tooth wear accompanied by the compensation of alveolar bone and defect of several central incisors due to chronic periodontitis. 상, 하악 전치부 치아의 비심미적인 비율을 갖게 되는 원인은 매우 다양하다고 보고된다. 특히 하악 치조골의 정출을 동반한 전치부 치아의 마모 시, 치은연 상승에 의한 치은 노출 양 증가 및 부적절한 치아 비율로 인해 심각한 기능적, 심미적 문제를 일으킬 수 있다. 이런 경우, 임상적, 방사선학적 방법을 이용한 수직고경 평가와 함께 미소선, 연조직 및 경조직의 형태뿐 아니라 치아의 해부학적 형태와 비율 또한 고려하여야 하는데, 수직고경의 증가 또는 임상적 치관 연장술 및 보철적 수복을 통해 치아간의 근/원심, 폭/길이 비율을 개선시켜야 하며, 이 때 전방 유도를 함께 고려해야 심미적, 기능적으로 만족스러운 치료결과 및 예후를 얻을 수 있다. 본 증례는 48세 남성 환자로서 만성치주염으로 인한 상악 좌, 우측 중절치 및 하악 좌측 중절치의 결손, 하악 전치부 치아의 마모 및 치조골의 정출 등으로 인하여 비심미적인 상, 하악 전치부 비율을 갖고 있었으며, 체계적인 진단 및 치료계획을 통해 기능적, 심미적으로 만족할 만한 결과를 얻었기에 이를 보고하고자 한다.

N/A The Precipitation behavior of Al-Li-X(=Ti, Zr) alloys produced by a rapid solidification process and heat treated in the temperature range of 160℃ to 240℃ was investigated. The solid solubilty If Li atoms was shown to extend to 4.95w/o. The discontinuous precipitation reaction resulted from the preferential growth of δ´ phase. Also, the driving force of the growth was depend on the fluctuations of solute concentration. The coarsening rate of δ´phase followed a (time)^(⅓) dependency obeys the MLSW theory. The addition of Ti or Zr had a little effects on the formation amount better than the growth rate of δ´phase.

The goal of the transitional system in post-Mao China is to establish a new economic governance structure that reduces the planning control of the state domains, and enlarges the autonomy of the market domains. By using the concept of a policy network, this article analyzes the changes in the state-market relationship and the formation of a new economic governance structure, which is in the process of a system transition. For this analysis, Chapter Three discusses the reform process of economic management organizations of the Chinese government with reference to the market system and appearance of the NGOs (non-government organizations). The NGOs play the role of intermediation by relating to both the state and market. Chapter Four discusses the interaction mode of the state and market by focusing on personnel resources, financial resources, information resources and legitimacy resources. The Chapter later examines the character of the policy network. The Chinese policy network does not deviate from the category of corporatism concept, however it has dual characteristics that accommodate the institutional legacy of a planed economic system, and that is adapting to the new circumstances of a market economic system. Finally, it shows possibility of a new economic governance structure.

중국 상하이의 도시 거버넌스와 국가-사회관계

정해용(Jeong Hae-yong) 고려대학교 아세아문제연구소 2008 亞細亞硏究 Vol.51 No.1

Through the reform and openness policy, the urban space of China has rapidly changed, so the urban regime could not confront with the social complexity through the past control apparatus anymore. In this context this study examined how the urban regime ruled by the Communist Party has endeavored for maintaining the governable society in the case of Shanghai, and whether those endeavors are the reflection of the continuity of past apparatus or the start of new transition. In the concrete this study firstly examined how the internal policy process of the party-government system has changed, and which meaning has the various government reform measures and growth coalition appeared in the urban development process to the urban governance. Secondly, after the reform and openness policy, under the conditions of shifting the axis for social management to grass-roots unit because of relaxing danwei(?位) system, it was examined whether the new changes such as community(社?) construction are democratic participation and the strengthening of autonomy or the striving process for a new control instrument. Thirdly, in the process of deepening class stratification and expanding the organization of social groups, it was examined how the state-society relationship in urban level has developed, and how the newly formed various interests are accepted and communicated by the urban regime.

중국 상하이(上海)의 도시발전 전략과 세계도시 전망

정해용 ( Hae Yong Jeong ) 국제지역학회 2005 국제지역연구 Vol.9 No.2

이 연구는 중국 상하이의 도시발전 전략이 역사적으로 어떻게 제기되어 왔는지, 그 과정에서의 성과와 한계, 그리고 체제적 특수성과 도시정치의 성격을 어떻게 규정할 수 있는지, 나아가 세계도시를 지향하는 현재의 발전전략은 어떠한 한계와 가능성을 갖고 있는지를 검토하는 데 목적이 있다. 상하이의 발전담론은 1980년대 도시성장의 위기를 거치면서 1990년대 푸동(浦東)개발을 계기로 이른바 중국경제의 용머리(龍頭) 전략으로 표출되었다. 이를 실현하기 위한 정책수단은 크게 도시의 환경적 여건을 개선하여 외자를 유치하려는 공간촉진 전략과 산업구조 조정이나 전략산업 육성 등 정부주도의 시장개입 전략이 주로 활용되었다. 이러한 상하이의 도시발전 과정은 중앙정부의 국가 프로젝트로 시작되었지만, 그 과정에서 도시 내부에 새로운 성장연합이 등장함으로써 가능하였다. 그러나 1990년대의 도시발전 전략은 적지 않은 한계를 드러내었고, 이를 극복하고 중국의 WTO 가입 등 새로운 체제환경에 적응하기 위한 세계도시 담론이 새롭게 제기되었으며, 최근 상하이의 세계도시 경쟁력은 크게 강화되는 것으로 평가할 수 있다. The purpose of this paper is to review: first, how the urban development strategy of Shanghai is historically put forward; second, what are the achievements and limits of this strategy; third, how to define the particularities of system, and the characteristics of Shanghai`s urban politics; and lastly what kind of limits and possibilities are included in the present development strategy for being a world city. The discourse of development of Shaghai is put forward, through the crisis of urban growth in 1980`s and the launch of the Pudong New Development Zone in 1990s, which is so called the Dragon Head project of Chinese economy. As for the policy implementation of this strategy, two strategies were used: place promotion which is intended to induce foreign investment through the improvement of the urban environment, and the government inducing market intervention for the adjustment of industry structure, the advancement of mainstay industry and so on. The process of urban development of Shanghai was initiated as the national project of central government, but its success was only possibile owing to the appearance of the new urban growth coalition. In addition, the urban development strategy of 1990s revealed comparative limits, so in order to overcome these limits and to adapt the new environment of WTO system, Shanghai raised the world city strategy and already was strengthened the competitiveness as a world city.

This study focusing on the Shanxi Province, examines which factor of the regional policy in China's reform era has induced the differential regional policy, what kind of political economic situation was brought about as the result of that policy in underdevelopment region, and in recent for the purpose of resolving that problem, how the central-local interaction is progressed. In Mao period, Shanxi Province has accomplished the continuing economic growth owing to the inland oriented policy. But in the reform era, because of coastal oriented development strategy of the central government, non-preferential policy to the inland province, the differential price structure between the region, the role of energy base to the coast region, and the political control of central government, Shanxi Province has entered the path of underdevelopment. With the result, in Shanxi Province, the transition process to the market economy system has delayed and the bureaucratic governance structure was embedded, so that resolving this problem, in recent it is broadly accomplished the policy coordination within the central-local interaction. This coordination is accomplished through the decisive reform of local party-government governance system, and the example of this coordination is presented at the ‘yinhuangrujin(引黃入晋) project' as the typical example of problematic policy enforcement case at Shanxi Province.

6·25 전쟁 전후의 경계 공간에 대한 공간적 고찰

정해용 ( Hae-yong Jeong ) 한국지리정보학회 2019 한국지리정보학회지 Vol.22 No.1

본 연구는 한반도 분할과 관련된 경계에 대해 공간적으로 분석한 것이다. 북위 38°선에 대한 추출과 정전협정 전문의 부록의 지도를 디지타이징 함으로써 그 범위를 추출하였고, 정전협정 전문과 부록, 유엔사 규정 등 근거로 하여 보다 정확한 범위를 추출하고 잘못된 정보에 대해 올바르게 분석하고자 하였다. 비무장지대의 범위는 UNC 551-4(2014)와 UNC 551-5(2015)에 의거남방한계선의 위치 변경이 없음과 비무장지대 내 군사정전위원회 본부구역이 제외됨을 확인하였다. 그 결과 비무장지대의 면적은 889.7㎢로 측정되었다. 군사분계선과 한강하구수역의 표식물을 확인하였으며, 특히 군사분계선의 표식물의 간격은 관리주체에 따라 다름을 확인할 수 있었다. 본 연구를 기점으로 보다 정확한 자료로써 공신력 있는 기관에서의 검증을 거쳐 DMZ 및 접경지역연구, 교육에서 필요한 기초자료로서 활용할 수 있을 것이다. This study is a spatial analysis of the boundaries related to the division of the Korean peninsula. The boundary space was extracted by extracting 38th parallel and digitizing the map of the Armistice Agreement Annex. The purpose of this analysis was to extract more accurate scope based on the armistice agreement, the appendices, and the UNC regulations and to analyze the wrong information correctly. The range of demilitarized zones was determined by UNC 551-4(2014) and UNC 551-5(2015) to ensure that there is no change in the location of the Southern Limit Line. It also confirmed that the MACHA was excluded in the DMZ. As a result, the area of the DMZ was measured at 889.7㎢. Also this study identified the interval and number of markers in the MDL and the Han River estuary. It could be confirmed that the interval of markers within the MDL depends on the subject of management. This study is more accurate from the start and can be used as basic data needed in the study and education of DMZ and border areas after verification by public organizations.
