전립성 결절성 증식증의 발병기전을 형태학전으로 규명하고자 10례의 환자에서 적출된 전립선을 광학 및 전자현미경적으로 검색하였으며 전립선의 분비선과 간질조직의 증식정도를 알기 위하여 형태계측법을 시행하였다. 아울러 대조군으로 2례의 부검시 적출된 정상인 전립선을 같은 방법으로 검색하였다. 그 결과를 요약하면 다음과 같다. 대조군에서 전립선의 분비선 상피세포는 분비과립, lysosome,mitochondria,ER 및 Golgi장치가 풍부하였으며 간질조직의 평활근세포 및 섬유아세포는 세포소기관의 양이 빈약하였다. 결절성증식증에서는 분비선 상피세포는 분비과립과 lysosome이 약간 있었을뿐 세포소기관의 양이 적었다. 간질조직에서는 평활근세포 및 섬유아세포내의 세포소기관의 양이 증가되었다. 형태계측법에 의한 전립선의 분비선 대 간질조직의 비는 대조군에서 0.28±0.04이었으며 결절성 증식증에서는 0.10±0.03으로 간질조직이 증가되었다. 이상의 성적으로 보아 전립선의 결절성 증식증은 일차적으로 간질조직의 증식에 의해 일어나는 질환으로 인정된다. Normal and prostatic nodular hyperplasia were studied by quantitative light microscopic measurements and electron microscopy. Two cases of normal prostate obtained from the autopsy and ten cases of nodular hyperplasia were examined. Electron microscopically, glandular lining cells of the normal prostate showed abundant secretory granules, lysosomes, endoplasmic reticulums, mitochondria, and Golgi apparatus. Smooth muscle cells and fibroblasts had a few cell organelles. the epithelial cells of the hyperplastic glands demonstrated less cell organelles. However, smooth mucle cells and fibroblasts revealed abundant cell organelles. On the morphometry, the ratio of gland to stromal tissue were 0.28±0.04 in control group and 0.10±0.03 in nodular hyperplasia. According to the above results, it is suspected that the nodular hyperplasia is primarily a stromal disease.

A 34-year-old man was stabbed with knife in the left fourth intercostal space. He was admitted to Kyung Hee University Hospital Emergency room with Cardiac tamponade state. Through a left anterior thoracotomy, a tense hemopercardium was released. A 2㎝ wound of right ventricle was sutured with 3-0 prolein. Seven month after the injury he was readmitted for cardiac catheterization. Cardiac catheterization confirmed the presence of an interventricular septal defect in the membranous septum with left ventricle to right ventricle shunt. A laceration of the septal leflet of mitral valve was also demonstrated. The pulmonary blood flow as 1.22 times the systemic flow. A longitudinal incision was made on the right atrium on the cardiopulmonary bypass. An 1×0.5㎝ interventricular septal defect was found in the membranous septum. In order to achieve and adequate repair interventricular spetal defect and mitral insufficency. The ventricular septal defect was repaired 3-0 prolein plegeted suture with interrupted. Artifical atrial septal defect was made and the septal leflet defect(1.5㎝) was reattached with 3-0 prolein plegeted suture interrupted. The partient had and uneventful post operative recovery and was discharged the Hospital on the 24day post operative day.

This study investigates the decisive factors affecting the survival or collapse of cable networks in the Korean paid broadcasting market from 1993 to 2010. The effects of performance variables discussed in previous studies were verified through survival analyses. According to the results, the most influential factors in the survival of cable networks were horizontal integration (MPP), channel genre, the scheduling of HDTV content, and the proportion of access program scheduling. These findings imply that the differentiation strategy of content suppliers is the most decisive factor among all business performance-related factors. Specifically, the content supply power and strategy of the program provider (PP) have the greatest influence on cable network viability. The present study is meaningful as the first attempt to establish the performance of PPs in Korean pay broadcasting markets through the viewpoint of organizational mortality. Accordingly, the present study can supplement the results of cross-sectional studies conducted with smaller samples.

ICT contents market is globally considered as an industry of high added value, where sustainability is accomplished through stories that cover wide range of consumers. However, the need for long-term internationalization strategy is growing as countless number of applications and games has pushed the local market to its limit. Thus, this research explored on the industrial characteristics and the internationalization of ICT contents firms through acquisition of competency. Based on Resource Dependence theory, the authors studied how pursuit of legitimacy and autonomy functioned in the expansion process of ICT contents firms. A survey analysis of 212 key decision makers of Korean ICT content firms were performed, to reveal that resource environment and interdependence must undergo a thorough consideration.

Truing process is a very important process for recovering the shape of wheels worn by continuous grinding operation. In this study, the devices, controller, and spindle for electro-discharge truing were developed, and the electro-discharge truing method was applied to metal-bonded grinding wheels and compared with the conventional truing method. The shapes of the grinding wheels were measured by a surface profile measurement device. The protrusion of abrasives on the surface of the wheels was compared with the conventional truing method using an optic microscope measurement device. The experimental results showed that the performance of the electro-discharge truing method, in terms of the protrusion of abrasives on the surface of the wheels and the recovery of the shape of the worn wheels, was similar to that of the conventional truing method.

본 연구는 중소기업청의 자료를 기반으로 창업보육센터가 제공하는 ‘보육활동’과 ‘운영모델 특성(운영주체, 소재지, 특화 여부)’이 창업보육 성과에 어떠한 영향을 미쳤는지를 실증적으로 살펴봤다. 분석결과 ‘교육지원’ ‘경영컨설팅지원’ ‘기술지원’ ‘마케팅지원’ 등의 보육활동이 보육기업 매출 증가에 긍정적 영향(+)을 미치는 것으로 나타났다. 더불어 공공이 운영하는 창업보육센터가 민간 운영 보육센터보다 성과가 더 좋은 것으로 밝혀졌다. 그러나 창업보육센터의 특화는 보육기업의 매출과 고용에 오히려부정적 영향(-)을 미치는 것으로 나타났으며, 창업보육센터의 소재지에 따른 이점 또한 확인할 수 없었다. We empirically studied the impact of incubating programme and business incubator operation (operational subjectivity, location and specialization) to start-up companies`` sales growth and labor environment. Main variables, such as educational support, business consulting, technological base and marketing channel were positive to start-up``s sales growth. However, the relationships between main variables and hiring rates were not significant. Furthermore private finance based incubators, were less influential than public organizations. Specialization strategy of business incubators was negative to incubating performance (sale growth and labor environment of start-ups). This paper indicates that multiple side of business incubators by testing empirically the relationship between operational characteristics and organizational performance.

본 연구는 정부의 다양한 정책 유형과 창업기업의 성과 간의 영향관계를 실증함으로써 혁신과 고성장 창업을 촉진할 수 있는 정부 지원정책의 방향성을 점검한다. 이를 위해 국내창업 생태계의 특성과 정책이슈를 전반적으로 점검하고, 최근 6년간 정부지원을 받은 창업기업을 대상으로 각 정책 유형이 매출과 고용성과에 미치는 영향력을 분석했다. 패널 회귀모형을 통해 분석한 결과 ‘지원 수단’ 중에서는 ‘기술개발’과 ‘사업화’ 지원, ‘창업교육’, ‘창업자금융자’ 등 창업기업의 역량을 높이는 주는 사업이 창업기업의 성과 증진에 기여한 것으로 나타났다. ‘지원 대상’의 관점에서는 ‘청년’, ‘시니어’ 그리고 ‘재 창업’ 지원이 창업기업성과에 유의미한 영향을 미쳐 맞춤형 지원의 실효성을 확인할 수 있었다. 마지막으로 ‘지원방식’ 특화에서는 창업기업의 정책수요를 종합적으로 고려한 ‘패키지 지원’의 효과를 확인했다. 본 연구는 창업의 경제적 성과와 사회적 성과를 종합적으로 고찰했다는 데에 그 의의가 있다. This study examines the performance of startup promotion program from various types of policy, and explores the supportive programs to promote the innovation and high performance of the startup companies. It focuses on the overall attributes of startup ecosystem in Korea with policy concerns, and studies the performance of policy based on the group of startups receiving governmental support for the past six years in terms of sales and employment. This empirical study is analyzed through panel regression model and confirmed ‘supporting programs’ which directly transfer the resources such as technology development and industrialization support, startup educative program, investments for startup funds supports the improvements in the performance of startup companies. Moreover, the study found evidence supporting ‘the young’, ‘seniors’, and ‘re-startup’ are significant for the performance as ‘supporting target’. Lastly, ‘supporting mode’ demonstrated that providing the integrated solutions over the stages in the business gives the actual effect. Therefore, this study implies the economic and social performances in startups.
