The human mandible is always under the condition of loading by the various forces extorted by the attached muscles. The loading is an important condition of the stomatognathic system. This condition is composed of the direction and amount of forces of the masticatory muscles, which are controlled by the neuromuscular system, and always influenced by the movement of both opening and closing. Mandible is a strong foundation for the teeth or various prostheses, nevetheless it is a elastic body which accompanies deformation by the external forces on it. The elastic properties of the mandible is influenced by the various procedures such as conventional restorative treatments, osseointegrated implant treatments, reconstructive surgical procedures and so forth. Among the treatments the osseointegrated implant has no periodontal ligaments, which exist around the natural teeth to allow physiologic mobility in the alveolar socket. And so around the osseointegrated implant, there is almost no damping effect during the transmission of occlusal stress and displacements. If the osseointegrated implants are connected by the superstructure for the stabilization and effective distribution of occlusal stresses, the elastic properties of mandible is restricted according to the extent of 'splinting' by the superstructure and implants. To investigate the change of elastic behaviour of the mandible which has osseointegrated implant prosthesis of various numbers of implant installment and span of superstructre, a three dimensional finite element model was developed and analyzed with conditions mentioned above. The conclusions are as follows : 1. The displacements are primarily developed at the area of muscle attachment and distributed all around the mandible according to the various properties of bone. 2. The segmentation in the superstructure has few influence on the distribution of stress and displacement. 3. In the load case of ICP, the concentration of tensional stress was observed at the anterior portion of the ramus($9.22E+6N/m^2$) and at the lingual portion of the symphysis menti($8.36E+6N/m^2$). 4. In the load case of INC, the concentration of tensional stress was observed at the anterior portion of the ramus($9.90E+6N/m^2$) and the concentration of tensional stress was observed at the lingual portion of the symphysis menti($2.38E+6N/m^2$)). 5. In the load case of UTCP, the relatively high concentration of tensional stress($3.66E+7N/m^2$) was observed at the internal surface of the condylar neck.

최근 한국 정당의 개혁조치에 대한 평가

김용호(Yong-Ho Kim) 한국정당학회 2008 한국정당학회보 Vol.7 No.1

이 글의 목적은 2002년 3김 은퇴 이후 한국정당이 시도한 개혁조치를 평가하고, 향후 새로운 정당발전 방향을 제시하는 것이다. 평가의 대상은 지구당 폐지, 지지자중심의 정당 만들기, 원내정당화, 국민참여경선제, 당정분리 등이다. 이러한 개혁조치는 3김 정당정치의 폐해인 고비용 정당구조, 머신정당, 비민주적 공천제도, 제왕적 총재문제 등을 해결하는 데 상당히 기여하였다. 그러나 이러한 개혁조치들이 예상하지 못한 새로운 문제점을 초래하였는 바, 기존의 지방정당조직과 당원의 충성심을 약화시켜 정당조직의 역할이 매우 축소되는 바람에 미디어와 시민단체와 네티즌집단 등의 정치적 영향력이 상대적으로 강화되었다. 앞으로 한국정당은 국민의 생활정치 요구를 입법화하여 삶의 질을 향상시킴으로써 정당지지자를 많이 모아서 명실상부한 대중정당을 건설하는 것이다. The major purpose of this paper is to evaluate recent reforms which South Korean political parties have so far made since political retirement of the longtime party leaders often called “three Kims” in 2002. These reforms include the legal abolition of the local party chapters at the electoral district-level, the introduction of U. S.-style primary system to elect presidential candidate, some attempts to transform a machine-type party into a parliamentary-oriented party for the autonomy of the party’s parliamentary members, and the reorientation of the member-centered party management into the supporter-oriented one. These reforms certainly contributed to a certain degree to the elimination of some negative aspects of the “three-Kims-style” party politics. At the same time, these reforms had also brought some “unintended” consequences of weakening the party's organizational strength as well as the partisan loyalty of party members. Hereafter, the South Korean parties need to cultivate their support bases at the grass-roots level by providing more substantial benefits to the voters with the effective legislation of the economic and social polices.

김정은 체제 외교정책변화의 결정요인 분석: 대북제재와 국내정치 동학

조현용 ( Jo Hyun-yong ),정기원 ( Jung Key-one ),김용호 ( Kim Yong-ho ) 국방대학교 안보문제연구소 2019 국방연구 Vol.62 No.4

이 글은 2018년 정상회담을 계기로 나타난 김정은 외교정책 변화의 결정요인을 분석하고 있다. 보다 구체적으로 북한 외교정책의 변화를 대내외 변화에 대한 정치적 동학을 통해 규명함으로써 북한의 대내정치 과정에서 파생되는 정치변수들에 대한 분석 역시 한반도 비핵화를 둘러싼 국제정치적 동학 못지않게 중요한 작용을 하고 있음을 주장하고 있다. 독재체제의 정권유지와 경제발전에 대한 정치경제이론을 적용하여 이념 중립적 시각에서 정책변화의 동인을 추적하였으며 기존연구들이 간과해 온 국제환경과 국내정치 간의 상호작용 동학에 의한 변화라는 대안적 분석틀을 제시했다. 이 과정을 통해 도출된 외교정책변화의 핵심변수는 대외요인으로 ‘자원권력’, 국내정치요인으로 지도자의 ‘정치적 생존’과 ‘정치체제’로 나타났다. 김정은 정권의 외교정책변화는 경제제재에 의한 북중무역의 붕괴로 촉발된 것으로 분석되며, 내부적으로 지배연합에 대한 통제력 강화, 군부의 정치 영향력 축소, 제도적으로 당-국가체제 확립을 통한 국내정치적 필요라는 변수가 작용한 것으로 분석됐다. The article analyzes the determinants of North Korean foreign policy in the wake of the 2018 summit. The paper argues that his new foreign policy initiative was motivated by his perceived shortage in his co-optation resources resulted from Chinese active participation on international sanction. In particular, Chinese participation in the ban of coal export triggered his policy changes because North Korea’s export of coal has served as the key source of North Korea’s co-optation resource to maintain Kim’s political survival. In so doing, the paper focuses on the interaction between international environment and domestic politics, which previous studies have overlooked. This paper also identifies key variables of North Korea’s foreign policy changes, “resource power” as external factors, and the leader's “political survival” as domestic variable.

Purpose: We have carried out prospective randomized clinical trial to compare survival benefit and side effect among three postoperative adjuvant chemotherapeutic regimens in serosa-negative gastric cancer patients. Materials and Methods: Total 317 cases were recognized as serosa negative and randomized into three groups at operating room. Out of them, 172 cases were excluded because of various reasons and 135 cases were analyzed finally; Group A 36 cases, Group B 49 cases, Group C 50 cases. Group A were treated with intravenous FP combination therapy, group B with MF combination therapy and group C with oral $UFT^{(R)}$ (mixture of Tegafur and Uracil) for one year. The median follow-up period was 30 months. Results: $88.9\%$ of Group A, $83.7\%$ of Group B and $90.4\%$ of Group C received adequate chemotherapy. The complication rates of Group A ($44.4\%$) was significantly higher than group B ($20.4\%$) and group C ($24.0\%$)(P<0.05). Most frequent complications were nausea and vomiting. The 3-year survival rates and disease-free survival rates were $92.2\%$ and $89.9\%$ respectively (Group A: $96.6\%,\;87.8\%$, B: $90.3\%,\;87.7\%$, C: $95.7\%,\;93.8\%$). There were no significant differences in survival rate and disease-free survival rate among the three groups (P>0.05). Conclusion: This study might suggest that the survival benefit of postoperative adjuvant chemotherapy for gastric Pseudomonas aeruginosa, and therefore it may be a useful adjunct tool for detection of Pseudomonas aeruginosa infection in combination with other conventional techniques.

민주화이후 한국 대통령제의 진화과정 분석

김용호 ( Kim Yong-ho ) 한국의회발전연구회 2017 의정연구 Vol.23 No.1

이 글은 비교정치제도적 시각에서 민주화이후 지난 30년간 한국 대통령제의 진화과정을 분석, 평가, 전망하였다. 민주화이후 한국 대통령제는 3김시기의 제왕적 대통령제에서 3김이후 “대통령중심적 대통령제(president-centered presidentialism)”로 진화하였다. 이러한 진화과정에 제도적 요인(정치자금법을 비롯한 주요 정치관련법, 각 정당의 제도 개혁)과 비제도적 요인(대통령의 리더십성격)이 작용하였다. 이러한 진화과정을 분석한 결과 우리들은 앞으로 정치제도개혁을 통해 현행 “대통령중심적 대통령제”를 “대통령-의회 권력분립형 대통령제”로 발전시킬 가능성을 발견하였다. 특히 지난 30년간의 민주화 추세를 고려해보면 한국 대통령제가 장차 권력분립형 대통령제로 발전해 나갈 수 있을 것으로 전망된다. 이제 통치과정에서 대통령 우위의 “대통령중심적 대통령제”에서 벗어나 앞으로 행정, 입법, 사법 3부가 서로 대등한 통치의 주체로서 견제와 균형을 이루어 민주주의를 발전시켜 나가야 한다. 그동안 국회의 대통령 견제와 감독기능의 증가, 사법부의 독립성 증대, 시민사회의 책임 있는 정치적 참여 증가등이 권력분립형 대통령제를 가능하게 할 것으로 본다. 따라서 지난 30년간 대통령제하에서 우리들이 이룩한 민주적 성과를 유지, 발전시켜 나가려면 현행정부형태를 바꾸지 않고 대통령제를 유지하는 가운데 현행 대통령제의 문제점을 시정해 나가는 것이 바람직하다. 이를 위해 현행 헌법상의 대통령 권한을 축소하고, 4년 중임의 정부통령제로 변경하는 개헌이 필요하다. 또 현행 헌법의 내각제적요소를 제거해야 한다. 그리고 권력분립형 대통령제를 뒷받침할 수 있도록 국회제도, 정당제도, 선거제도, 대선후보 경선제도를 개선하고 대통령제와 관련된 잘못된 인식과 잘못된 정치적 관행을 고쳐 나가야 한다. The major purpose of this paper is to analyze the evolution of the presidential system in South Korea during the past three decades ever since the country`s democratization in 1987 from the comparative institutional perspective. As imperial presidentialism during the so-called three Kim`s era(1987-2003) disappeared right after the political retirement of the three Kims in 2003, then president-centered presidentialism emerged during the post-three Kim`s era, since the country`s recent three presidents possessed their relatively low-level of partisan power in terms of their control of National Assemblies and their respective presidents` parties during their presidencies. South Korea has now a strong possibility to transform the current president-centered presidentialism into the American-style separatist presidential system in the near future, since the country`s National Assembly has continuously been making its efforts to function as an effective governing body being compatible with the American Congress. In addition, the country`s judiciary branch has effectively been playing a political role like the US supreme court ever since the country`s democratization in 1987. It is also emphasized that South Korea`s civic society is currently playing as a guardian of democracy through its effective and responsive political participations in many public sectors for promoting civic liberties, public welfare, and other democratic values. South Korea now needs to carry out constitutional revisions, political reforms of legislative system, party system, and electoral system as well as correct some contradictory political understandings and habits in a way to transform the current president-centered presidentialism into American-style separatist presidential system in the near future.

Sympathetic ganglionic stimulants (DMPP, Wy-615, TMA and McN-A-343) produced pressor response in chickens anesthetized with phenobarbital sodium. In adrenalectomized chickens the pressor activity of DMPP, Wy -615 and TMA was less than in normal chickens but that of McN-A-343 was unchanged. Hexamethonium (20 mg/kg) and chlorisondamine (5 mg/kg), ganglionic blocking agents, reduced the pressor response to DMPP and Wy-615 but did not abolish the response. The pressor effect of McN-A-343 was not potentiated by the ganglionic flocking agents, but abolished by atropine.

The powder manufacturing process using the gas atomizer process is easy for mass production, has a fine powder particle size, and has excellent mechanical properties compared to the existing casting process, so it can be applied to various industries such as automobiles, electronic devices, aviation, and 3D printers. In this study, a modified A4032-xSn (x = 0, 1, 3, 5, and 10 wt.%) alloy with low melting point properties is investigated. After maintaining an argon (Ar) gas atmosphere, the main crucible is tilted; containing molten metal at 1,000℃ by melting the master alloy at a high frequency, and Ar gas is sprayed at 10 bar gas pressure after the molten metal inflow to the tundish crucible, which is maintained at 800℃. The manufactured powder is measured using a particle size analyzer, and FESEM is used to observe the shape and surface of the alloy powder. DSC is performed to investigate the change in shape, according to the melting point and temperature change. The microstructure of added tin (Sn) was observed by heat treatment at 575℃ for 10 min. As the content of Sn increased, the volume fraction increased to 1.1, 3.1, 6.4, and 10.9%.
