This article researched the changes of terrestrial local broadcasting companies in a crisis of management. According to the following: First, the structure of the internal organization of local broadcasting companies has been changed to put more emphasis on 'management'. Second, most of the interviewees responded that this change was an inevitable choice. However, some responded that their 'role identity' was changing in a negative direction. Third, these changes have led to the emergence of programs that could undermine public interest. It also showed an increase in the production of 'funding-based' programs and 'mobile first' programs.

The purpose of the present study is to investigate the structural relationships of work-family culture, work-family balance and organizational commitment among Korean hotel employees. In order to achieve the study goal, frequency analysis, confirmatory factor analysis, reliability analysis, correlation analysis and covariance structure analysis were undertaken using SPSS(18.0) and AMOS(18.0). The results showed that 'managerial support' had a significantly positive effect on work-family balance, and 'fewer negative career consequences' had a significantly positive effect on affective organizational commitment. In addition, work-family balance had a significantly positive effect on affective organizational commitment, Hence, in order to enhance employees' affective organizational commitment, the atmosphere in which employees can take advantage of family-friendly policies without any worry about the future disadvantages should be built. Also, management has to consider employees' work-family balance to be important and needs to develop various policies to keep employees' work and family stability.

최근 손상된 생체조직의 재생 또는 대체를 위하여 다공성의 지지체(scaffold)를 이용하는 연구가 활발히 이루어져 왔다. 지지체 재료는 조직 재생을 목적으로 하는 경우에는 생분해성 고분자, 생흡수성 세라믹스 또는 이들의 복합재료가 사용되고, 조직 대체를 목적으로 하는 경우에는 금속 또는 세라믹스 재료가 단독으로 사용된다. 현재 경조직 대체를 위한 임플란트 재료로 사용되고 있는 금속재료 중 대부분이 타이타늄 또는 타이타늄 합금이다. 타이타늄은 비강도, 내식성이 우수하며, 생체 내 환경에서 부동태피막 재생 속도가 빠르고, 섬유상 결체조직 형성 두께가 얇아 생체의료용 소재로서 각광을 받고 있다. 다공성 타이타늄은 기존 타이타늄 소재의 장점에 다공체의 구조적인 특성을 부가하여 하중을 받는 골 결손부에 사용될 경우 뼈와의 탄성계수 차이에서 기인하는 응력차폐(stress shielding) 효과를 최소화할 수 있고, 다공체 내부로 골조직 성장을 유도할 수 있어 지지체와 골조직이 일체화되는 골융합 효과의 극대화를 기대할 수 있다. 본 연구에서는 기공 구조를 다양하게 제어할 수 있고, 3차원적 연결 기공구조를 만들 수 있는 적층조형(layer manufacturing) 기술을 이용하여 3차원 다공성 타이타늄 지지체를 제조하였으며, 이에 대한 세포독성, 조골세포 증식능 등 in vitro 생체적합성을 평가하고, Rat model 을 이용한 in vivo 생체적합성을 평가하였다. 또한 지지체의 골조직 재생 유도성의 증대를 위한 생체활성처리 영향도 분석 평가하였다.

Since warfare surroundings getting complex and diverse in the future, it is not simple to make appropriate structures and organizations for military groups along the phenomenon. Therefore, this study proposes a methodology of verification for army staff's structure and organization by units in the future using System Dynamics(SD). The procedure of using SD for the verification is a calculation of database(DB), the design of causal loop diagram, and the simulation and analysis. First, DB such as individuals' workload and time is calculated through observation after a real group of staff. Second, the causal loop diagram is considered by a flow of task, and it is modeled. Third, the DB is entered into the model and simulated for analyzing of appropriacy. This study used Powersim program for designing the SD model. One of the weaknesses of the methodology of this study is possibilities of a different result by the DB by observers and perspectives by analysts. As supplementation for the weakness, this study includes research analysis and surveys for the total analysis. The meaning of this study is that it suggests a methodology of warfighting experimentation to analyze structure and organization of military groups with quantifying suitability in the scientific method.

Recent years have witnessed various attempts of firms to acquire new knowledge. Purchasing intellectual property or merger and acquisition (M&A) can be such attempts, but joint venture can also be an effective way internalizing new complementary assets from external partners. However, due to difficulties in the formation and implementation of learning strategies, many joint ventures have failed to acquire necessary knowledge. In this respect, based on contingency theory and dynamic capability, the current research aims to investigate the failure case of knowledge transfer in an international joint venture - KEFICO established by Hyundai motors and BOSCH. Case firm optimized for hardware technology but did not establish a differentiated learning strategy and organizational structure to acquire software skills, which are intellectuals of different natures. Due to this inconsistency, it was not able for KEFICO to absorb new type of knowledge (skills related to engine control system). This study suggests the theoretical framework illustrating the case and provides some important implications for organizational learning.

The purpose of this study is to interpret how the long-term care evaluation system implements in the actual service settings with institutional isomorphism and decoupling based on new-institutional theory. This study conducted in-depth interview with employees engaged in 7 long term care service facilities. Directed qualitative content analysis was used to analyze the data. As a result, unlike the intention of the long-term care evaluation system to improve the efficiency of the organization by market competition, it found that organizations forcibly adapted a evaluation system to rely on government's resources and it results in isomorphism phenomena which is similar between organizations. This results confirmed that the evaluation system has implemented in the direction of enhancing the government's role to standardize and institutionalize the long-term care service rather than improving the efficiency of the organization by market competition. This study also partially found the phenomenon of decoupling between organizational formal structure accompanied by isomorphism and real behaviors. These results suggest that it is required to improve government's evaluation indicators on the issue of inefficiency caused by dual structure of organizations. In addition, this study proposes that government's evaluation index which is reflected the characteristics of care service is necessary for operating.

For this study, 373 students of H cyber university were chosen to conduct a survey in the spring semester of 2011. The result of this study through structural equation modeling analysis was as follows: First, organizational support significantly affected perceived isolation. Second, organizational support and perceived isolation significantly affected satisfaction. Third, perceived isolation and satisfaction significantly affected learning persistence, while organizational support didn't. In addition, satisfaction was verified as a mediating variable between organizational support, satisfaction, and learning persistence, and satisfaction was verified as a mediating variable between perceived isolation, organizational support and learning persistence. These results imply that perceived isolation and organizational support should be considered for the design and development strategies of instructional courses in order to enhance satisfaction and learning persistence of students in cyber educational environment.

The development of group-specific tissue probability maps (TPM) provides a priori knowledge for better result of cerebral tissue classification with regard to the inter-ethnic differences of inter-subject variability. We present sequential procedures of group-specific TPM and evaluate the age effects in the structural differences of TPM. We investigated 100 healthy volunteers with high resolution MRI scalming. The subjects were classified into young (60, 25.92+4.58) and old groups (40, 58.83${\pm}$8.10) according to the age. To avoid any bias from random selected single subject and improve registration robustness, average atlas as target for TPM was constructed from skull-stripped whole data using linear and nonlinear registration of AIR. Each subject was segmented into binary images of gray matter, white matter, and cerebrospinal fluid using fuzzy clustering and normalized into the space of average atlas. The probability images were the means of these binary images, and contained values in the range of zero to one. A TPM of a given tissue is a spatial probability distribution representing a certain subject population. In the spatial distribution of tissue probability according to the threshold of probability, the old group exhibited enlarged ventricles and overall GM atrophy as age-specific changes, compared to the young group. Our results are generally consistent with the few published studies on age differences in the brain morphology. The more similar the morphology of the subject is to the average of the population represented by the TPM, the better the entire classification procedure should work. Therefore, we suggest that group-specific TPM should be used as a priori information for the cerebral tissue classification.
