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.

( Kyu Tae Kwak ),( Kyung Hee Song ),( Soo Kyung Park ),( Bong Gyou Lee ) 한국인터넷정보학회 2014 KSII Transactions on Internet and Information Syst Vol.8 No.2
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.

The purpose of this study is to improve the whitening phenomenon around the PET preform gate for blow molding. CAE analysis of plastic injection molding has been applied to design of preform shape and select the injection molding conditions. A ceramic insulation gate with lower thermal conductivity than metal is applied to improve the whitening phenomenon created around the gate in the injection molding process. According to the results of CAE analysis, the warpage deformation at the square corner was estimated to be about 0.34 mm at the bottom. From the results of the temperature history analysis, it was confirmed that the resin near the gate cooled more rapidly than the cavity. Ceramic insulated gates were fabricated to reduce the cooling rate and experiments were conducted to confirm the effectiveness of the whitening phenomenon improvement. As a result of the ceramic insulation gate experiment, it was confirmed that the whitening phenomenon was significantly reduced around the gate.

This investigation examined why users are resistant to the interaction in Mobile social networking environment. For the specified study on Mobile social network service (Mobile SNS), this study analyzed and suggested the antecedents of decreasing in usage of mobile SNS. Existing research were limited in the exploratory approach to direct relationship between materiality of IT system and user`s feeling stress. In addition, most past studies were focused on the technostress in work environment, mainly related with distraction when users face multitasking. To overcome weakness of naive approach, extending construct of stress in organization to general circumstance, we concerned some antecedents in terms of technology and society, Technology Use factor and Social Influence factor. This trial was helpful for searching explanatory variable of information overload and relation-burden that user experience in the ubiquitous space. Transaction based stress model (TBS), theoretical foundation in social psychology were suggested as holistic frame to analyze problem of technological use. In contrast to only stimuli based approach and response based analysis, TBS is specified and contextualized to interactive communication environment. It is expected to find user`s conduct and tendency in real complex world. Furthermore, relational attribute of the stress, relation burden were also concerned with main variable, for the expression of user`s resistance to networked society. Information overload, often discussed as the key feature of opened online community, were suggested as the main component of stress and core to decrease of task performance of user. For the sake of empirical support to this model, We surveyed 202 users who have the experience of using KAKAOTalk in their daily life. Since the KAKAOTalk is so familiar to most of phoneuser and dominant paradigm of ubiquitous society in Korea, it is inferred as representative exemplar of mobile social networking platform. Lisrel 8.54 and SPSS 18.0was used as analytical tools, and the research hypothesis was tested after verifying the reliability and validity through the analysis of the structural equation modeling. As a result, Ubiquity, Poly-chronicity and Simplicity were dominant reason to information overload in mobile communication. However, relation burden were only supported by two factors of social influence and simplicity, we inferred simple feature of interface and information structure is effective and dominant for the designing mobile social service. Furthermore, information overload and relation-burden were operated as the main factor to reluctant to use when users face with social interface. Results of this study illuminate some micro-structure in stress when user adopt Mobile SNS and expand established framework of stress research. It is expected for this work to re-conceptualize the context of social and technological based stress initiated in information systems research. On the other hand, when targeting the range of Mobile SNS only single services were considered, and considering entire KAKAOTalk users as the range, the number of sample is relatively small. Also there is limitation of not being able to consider individuals` mechanism for coping with stress. Nevertheless, this study has the following theoretical significances. First, this research attempts to review the concept of stress in the context of dyfunctional usage of SNS, and also provided the basis for the theorization of Mobile SNS stress. Existing studies on SNS have intermittently discussed on the relationship between the negative perception of SNS usage and its actual use, but have also been understudied in social scientific conceptualization of the actual social stress, mobile stress, and SNS stress. Since there have been cases that did not specifically distinguish stress influence factors and stress response factors, the concept of SNS stress that is proposed in this study will be able to provide new perspec

기업가정신/벤처/창업/정책 : 창업보육센터(BI) 운영성과의 영향요인: 보육활동과 BI 운영모델 특성을 중심으로
곽규태 ( Kyu Tae Kwak ),최세경 ( Se Kyoung Choi ) 한국중소기업학회 2015 中小企業硏究 Vol.37 No.4
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.
