In a one-stage approach, where the implant installation is performed simultaneously with the iliac bone graft, various complications are observed. The observed complications are as follows; severe bone resorption at the maxillary anterior region and the area adjacent to the nasal cavity, shortage of soft tissue to cover the augmented alveolar bone, difficulties with oral hygiene care caused by the diminished vestibular space and non-esthetic prosthesis. These are good reasons for choosing the two-stage approach over the one-stage approach in spite of all the advantages it has, and should be taken into careful consideration when diagnosing and planning treatment using the one-stage approach.

The deployable space structure is necessary to minimize the satellite volume and launch cost. For the deployment, passive deployment mechanism has widely been used to attenuate a latch shock induced when the structure is just fully deployed. To reduce the latch shock, viscous damper is applied to the passive deployment mechanism and it can control the deployment speed of the structure. In this paper, dynamic analysis of the deployable space structure using the passive deployment mechanism with the viscous damper has been performed. The viscous damping values have been optimized through numerical simulation. The satellite's attitude influenced by pyro activation for the release of the structure has also been investigated.

Objectives : This study is planned to classify correlation between thoracic kyphosis angle and prevalence of cervical intervertebral disc. Methods : We Measured the thoracic kyphosis angel of the 110 men and 179 women patients with neck pain in 00 Korean Medicine Hospital. We use Cobb's angle method and Thoracic cage dimension method for measuring the thoracic kyphosis. And We use Magentic Resonance Imaging(MRI) for classifying the patient who has cervical intervertebral disc or not. Results : 1. There was statistical difference on the thoracic cage dimension with gender(P<0.001), while there was no statistical difference on Cobb's angle with gender(P=0.882). 2. Age and thoracic cage dimension(r=0.383) is statistically more correlative than age and cobb's angle(r=-0.59). Conclusions : 1. Thoracic cage dimension and gender, Thoracic cage dimension and age were statistically concerned on patient who has neck pain, while Cobb's angle had no statistical correlation with age and gender. 2. There was no statistical difference on the Cobb's angle and Thoracic cage Dimension between patient who has one or more cervical disc herniation(Protrusion disc, Extrusion disc) segment and patient who didn't have cervical disc herniation(Protrusion disc, Extrusion disc) segment.

Vertical integration is a persistent structural phenomenon in the Korean film industry. Generally, vertical integration can incur both positive and negative effects. Its positive effect which occurs in the individual firm is gains in efficiency in resource management through internalization while the negative effect which occurs in industry level is a distortion of resources management by discriminating the non-affiliates. This paper analyzes the behaviors of two major film companies that achieved vertical integration from investment, production, distribution to screening. This paper is differentiated from the pervious literature by analyzing the discriminating behaviors of the major film firms in allocations of seats and time of screening to films of the non-affiliates. This paper shows that the major film companies treated its affiliates unfairly by allocating more number of seats in golden time to the films distributed by them. Even though the major firms treat its affiliates, its discrimination did not show good box-office performance. Therefore, in the Korean film industry, the vertical integration plays a kind of barriers for the non-affiliates to enter the film market. That leads to loss in efficiency of the Korea film industry.

영국의 베버리지언적 연금발전: 노인빈곤으로의 함의

최영준 ( Young Jun Choi ) 한국사회보장학회 2011 사회보장연구 Vol.27 No.2

본 연구는 영국에서 실시된 연금개혁의 핵심적 내용과 성격을 고찰하고 이러한 변화가 최근 노인빈곤의 추이에 어떠한 함의를 가지고 있는지를 분석하고자 한다. 영국의 연금개혁에 관해서는 일부 논문들은 소개된 바 있으나 연금개혁이 빈곤 등 복지성과에 어떠한 영향이 있었는지에 관련된 거시적 논의는 국내외적으로 거의 이루어지지 않았다. 이에 이 논문은 영국의 연금개혁 과정을 추적하면서 그러한 변화들이 최근의 빈곤에 어떠한 함의를 가지는지를 논하고자 한다. 영국은 전후 시기부터 국가가 최저수준을 보장하는 데에 초점을 둔 베버리지언적 연금발전을 해왔다고 일반적으로 평가받는다. 이러한 변화는 1970년대에 일부 변화 조짐이 있었으나 1980년대부터 대처정부에 의해서 강력하게 추진되어온 시장중심의 개혁을 통해서 국가가 일층을 담당하고 민간이 이층을 담당하는 뚜렷한 구조를 정착시키게 되었다. 1990년대 말에 들어선 신노동당은 빈곤문제 해결을 위해 기초연금의 강화를 추진하였으나, 보수당과 비교해 전반적인 연금구조와 개혁의 기조는 가장 최근인 2007년의 개혁까지 크게 변화하지 않고 있다. 기초보장을 핵심으로 하는 베버리지언 연금발전에도 불구하고, 최근 영국 노인가구의 빈곤의 변화를 살펴보면 그다지 성공적이지 못함이 나타난다. 보수당 시절 확대되던 불평등은 다소 완화가 되었지만, 신노동당에서 강하게 추진하였던 노인빈곤 감소 정책은 그다지 실효성 있지 못한 것으로 나타나고 있다. 이에 본 논문에서는 연금발전과 노인빈곤의 최근 추이를 통하여 영국의 자산조사를 기반으로 운영되는 노인기초보장제도가 가지고 있는 한계점을 지적함과 동시에 민간주도의 이층연금이 빈곤감소라는 차원에서 성공적이지 못했음을 지적하고 있다. The aim of the study is to analyse pension developments and reforms in the United Kingdom and their implications for old-age poverty. While much has been written on the British pension system, there are few studies on the relationship between pension reforms and old-age poverty in the United Kingdom, both domestically and internationally. Therefore, the research attempts to carefully examine the process of pension developments, on the one hand, and discusses how the process directly and indirectly has influenced old-age poverty. It is generally argued that the British social security is a typical Beveridgean-type model in which basic security and poverty prevention is a core concept. Though this feature seemed to disappear in the mid-1970s, market-oriented reforms driven by Thatcher government in the 1980s settled down the current structure of pension schemes where there is a strict divide between the public-managed first tier for basic security and the private-dominated second tier for income maintenance. The New Labour inaugurated in the late 1990s tried to strengthen the basic pension for poverty prevention, but the two-tier pension model has not changed until now. In spite of the Beveridgean-type developments, it is observed that old-age poverty has not been successfully eradicated in the United Kingdom. While inequality has been reduced compared to the Thatcher era, old-age poverty has remained more or less same in spite of the introduction of the minimum guarantee programme. This paper, therefore, points out the limitations of the current basic pension and the private-dominated second tier pensions in the terms of old-age poverty.

본 연구는 경추 및 흉추부 스트레칭과 근력강화 운동프로그램이 머리전방자세에 미치는 효과를 알아보고자 연구하였다. 머리전방자세를 갖고 있는 일반인 32명을 대상자로 자세교육과 운동프로그램을 적용한 실험군 16명과 자세교육만을 받은 대조군 16명을 대상으로 시행하였다. 두개척추각(CVA:Craniovertebral Angle)과 두개회전각(CRA:Cranial Rotation Angle)을 X-ray로 검사하고, PACS(Picture Archiving and Communications System) πviewTM 각도를 측정하였다. 연구결과 실험군은 두개척추각과 두개회전 각이 통계적으로 유의한 차이가 있었다. 그러나 대조군은 두개회전각에서만 유의한 차이가 있었다. 또한, 실험 전 그룹 간 차이는 없었으나 실험 후 그룹 간 비교에서는 통계적으로 유의한 차이가 있었다. 이 연구에서는 경, 흉추부 스트레칭 및 근력강화 운동프로그램이 연구대상자들의 머리전방자세를 감소시키는 척 추자세정렬을 향상시킬 수 있었다. 이 연구 결과들은 자세증진 치료들에 있어서 향후 발전되는 운동프로 그램을 위해 기초자료가 될 수 있다. This study was to find out the effect of cervical and thoracic stretching and strengthening exercise program on forward head posture. 32 adults had forward head posture were selected as the subjects for the study. The training program of the exercise group(n=16) consist of postural education with exercise program, subjects in the control group(n=16) participated in a postural education only. Postural measurements of Craniovertebral Angle(CVA) and Cranial Rotation Angle(CRA) were obtained from the using x-ray and PACS(Picture Archiving and Communications System) πviewTM. The results were compared with change of CVA and CRA exercise group were significant(p<.05) compared to the control group. However CRA of contol group was significant(P<.05). Also, there were no significant difference(p>.05) between groups on any pre-test measure. however there were significant difference(p<.05) between groups on CVA and CRA post-test measure. This study showed that cervical and thoracic stretching and strengthening exercise program can improve spinal posture alignment for decreasing forward head posture in subjects. These results can be fundamental data for further development of exercise program in interventions of postural improvement.

Recently, ready-mixed concrete companies are using disqualified aggregates which lack in both grade and grain shape due to the shortage of natural aggregate. However, still there aren t any clear and accurate blending method and quality standard existing. In this paper, we surveyed ready-mix concrete companies about the quality level and blending of aggregates in order to standardize the blended aggregates on concrete. Survey results indicated that blending of aggregates is common for the aim of quality improvement, and usually grade and grain shape were the main cause of the blending. To sum up the ready-mixed concrete companies view point, once the blended aggregate s quality standard is set, the supply shortage and quality problem of aggregates can be solved.

陽明學 志向者에게 보이는 ‘狂’의식 考察

최영준(Choi Young-jun),김춘희(Kim Choon-hee) 한국양명학회 2008 陽明學 Vol.0 No.21

역사적으로 볼 때 16ㆍ17세기의 동양사회는 구체제가 그 한계를 드러내면서 각종 사회 모순으로 말미암아 새로움과 변화에 대한 갈망과 에너지가 응집되던 시기였고 이와 더불어 사상적 문학적 업적을 남긴 천재적인 인물들을 많이 배출한 시기이기도 하다. 이지나 허균과 같은 사상적 문예적으로 천재성을 보였던 인물들이 바로 그런 사람들이다. 그러나 이들은 강력한 전제주의체제아래에서 주자학을 지배이념으로 삼는 집권지배층에 의해 대개는 세상을 어지럽히는 광혹한 인물로 지목되어 비극적인 삶을 살다가 생을 마감하였다. 본고에서는 먼저 역사의 전환점에서 역동적인 삶을 살다간 이들이 공통적으로 직면하였던 ‘광’의 의미를 추적해보았다. 그리고 새로운 질서를 위해 한계에 도전했던 인물들이 사회로부터 배척되는 과정을 살펴봄으로써 명대와 조선대에 있었던 ‘狂士’ 배척의 배경의 숨겨진 의미를 찾고자 하였다. 동서를 막론하고 세상을 놀라게 하는 업적을 남긴 천재들에게서 흔히 보이는 천재성은 광기와 가깝다고 알려져 왔다. 특히 예술 방면의 천재들에게서 흔히 기행이나 광기가 발견되는데 그렇더라도 그 때문에 우리는 그들을 제거해야 한다고 생각하지는 않는다. 왜냐하면 몇 몇 천재들에게서 볼 수 있는 광기라 부를 수 있는 번뜩임이 인류의 문학사 과학사 사상사를 더욱 더 풍요롭게 하였고 세상을 좀 더 밝은 곳으로 이끌어 나갔으며 인류의 문화를 좀 더 풍요롭게 해주기 때문이다. The 16th and 17th century oriental society had historically been a period where the old establishment revealed its limits. It was an era where objections toward the old and desperate desire for change had solidified due to various social contradictions. It was also an era where geniuses who produced eminent achievements in literature and philosophy appeared. Li Zhi and Heo Gyun were amongst those who displayed such genius in literature and philosophy. However, the two met their end, marked out by the ruling class who, under a powerful absolute monarchy, took Nee-Confucianism as the ruling ideology. The following study first tracks the meaning of “lunacy” which was the problem that both Li Zhi and Heo Gyun had to confront in their days. The study also examines the course and stage of how people who challenged limits to find new order for society had been rejected by society in the Ming and Chosun Dynasty. This will help find the hidden meanings of the background behind such ostracism. Across the ages and in all countries of the world, the acts of genius displayed by masterminds are known to be similar to madness. Such eccentricity and madness is observed particularly frequently for masterminds of the arts. Nevertheless, we do not believe that such geniuses deserve to be eliminated because of their eccentricity. The flash of genius from a few of these masterminds which in times may seem like madness has made the History of Literature, Science and Political Thoughts much more affluent. Such eccentricity is what has driven the world to a more brighter place and has greatly contributed into making the world more culturally prosperous.
