In response to the recent rapid technological and market changes, the importance of the design of ambidextrous organization has been increasingly emphasized as one of the dynamic capabilities. Firms that show a high performance in the rapid technological and market changes appear to design and implement ambidextrous organization successfully. They have achieved both exploitative competence for continuous innovation with product development and exploratory competence for discontinuous innovation with new market and new technologies. We have examined why and how to design and operate ambidextrous organizations and the effects of ambidextrous organizational characteristics on the performance from structural, contextual and leadership perspectives. We conducted case studies on 3 Korean firms that showed different characteristics of industrial product, company size, etc. Longitudinal case studies exhibit different processes of design and operating ambidextrous organization according to innovative strategy and industrial characteristics.

Soft tissue tumor classifications should be an important part of radiology, oncology and, for clinicians and pathologists, they provide diagnostic instruction and prognostic guidelines. In soft tissue tumor classification systems, the World Health Organization (WHO) classifications have become dominant, enabled by the timely publication of new 'blue books' which included detailed text and numerous good illustrations. The new WHO classification of soft tissue tumors was introduced in 2002. Because the classification represents a broad consensus concept, it has gained widespread acceptance around the globe. This article reviews the changes which were introduced the adipose tumors, fibroblastic/myofibroblastic tumors, so-called fibrohistiocytic tumors, smooth muscle tumors, pericytic tumors and skeletal muscle tumors which have been first recognized or properly classified during the past decade.

Histological study of eel was carried out to determine the effect of drying on muscular tissue and fat movement. The results are as follows: (1) Changes of muscular tissue during drying may he divided into two stages early and late. In the early stage there was apparent dehydration of connective tissue while in the late stage muscle fibre dehydration appears to occur. (2) Movement of fat during drying depends upon division and contraction of the myocommata caused by inner structural changes. This phenomenon appeared to be more apparent in the late rather than the early drying stage.(3) After freeze-drying traces of ice crystals were detected around the muscle cells. These ice crystals remained even after rehydration. (4) When muscular tissue was heated the connective tissue melted while muscle fiber dehydrated and solidified.

In the case of ICT-enabled organizational changes such as Smart Work, appropriate change management is required. To achieve work-life balance, organizational change management should be conducted from both a structural and a cultural perspective. This study looked at organizational factors that affect Smart Work facilitation through a case study with the view of ICT-enabled change management. From November to December 2019, eight Smart Workers of Company A were interviewed and analyzed for organizational support. The results show that structural support such as institutionalization, ICT infrastructure office environment improvement, Smart Work center as well as cultural support such as enhancing autonomy, communicating style of managers, trusting organizational climate are required. The findings suggest balanced organizational support to provide cultural support along with structural support for activating Smart Work operations. In the future, it is necessary to demonstrate the causality between structural/cultural support factors and outcome factors.

The prior purpose of this study is to introduce a optical biopsy and evaluate whether the optical biopsy, real-time, non-invasive technique, is a reliable tool to assess response to radiotherapy Four healthy volunteers, and four patients with inflammatory conditions of the oral cavity participated on the study. was obtained from each person enrolled in the study. Using FastEEM(Ercited Emission Matrix) as a optical biopsy tool, normal and tumor spectra are taken from the normal and the tumor regions. And then second optical biopsy are taken from the tumor regions in 4 patients with time delay at 7days.. Using a diagnostic algorithm, made by Gillenwater based on spectra excited at 337nm The Optical Biopsy turned out to be more suited for tumor diagnostic resulting in significant difference fluorescence spectra. The fluorescence intensity of cancerous tissue showed a higher position. The second fluorescence intensity of optical biopsy of cancerous oral tissue has more smaller than the first result. I conclude that optical biopsy, which technique don't need to remove tissue sample from body, and is a real time , and non-invasive measurement is a reliable tool to access to radiotherapy because FastEEM can do measure the variation of the tissue composition chemical, biological, and morphological after radiotherapy. Based on the fluorescence spectrum are taken from the optical biopsy in normal and tumor spectra as well as tumor spectra after 7days.

In this study, we measured the absorption coefficient of the tissues of mouse (brain, heart, liver, muscle and tumor) and human brain (normal and tumor) in the wavelength between 500nm~900nm. The optical coefficient is a representative of the characteristics of the materials. So, we can characterize the biological tissue with the optical coefficients. Using the spectrograph monometer and PDA(Photo Diode Array), we experimented with quick-frozen sectioned specimens. Because the optical coefficient is concerned with the conformation and biochemical component of the biological tissue, we experimented as the wavelength between 500nm~900nm on the normal and tumor samples of the animal and human. For the mouse, there are distinctive differences of the absorption coefficients between normal tissues and tumor. The absorption coefficient of the normal tissue varies 0.1~0.2cm$^{-1}$ with wavelength. But, the absorption coefficient of the brain tumor is changed round about 0.4~0.5cm$^{-1}$ as the wavelength. The absorption coefficients we measured can be a useful implement to detect diseases.

In recent years, many high-rise buildings have been constructed for the purpose of redevelopment of urban environments in Korea. However, generally the construction durations do not increase in proportion to the number of the floors or the height of the building. So new materials, equipments, and methods are applied to high-rise building construction in order to overcome this problem. In most cases, applying these new resources is considered mainly as the technical issue, and the organizational aspects of this is frequently overlooked. This study discussed the performance variance in time and identified the causes of time variance in high-rise building construction from organizational viewpoint .

This study analyzes the influence of the construction of a high-speed railroad on territorial organization in France. After development of a new transportation network, the French territorial organization has been largely modified. Many economic urban areas are modified by their position in the territorial hierarchy according to their condition of connection with the TGV network. At first, spatial convergence is the most important effect of the TGV network construction. Second, the development of a transportation network concentrated in the Paris area has influence as an intensified factor on metropolitan areas and as a weakening factor on middle- and small-sized cities. Thus, this system has risk in increasing territorial imbalance in France. Third, to implant an economic activity zone around new TGV stations, a new town or a new economic center starts to develop. This is going to grow into a second core outside of the old city center so that regional spatial organization is transformed from a mono-polarized(mono-centric) organization to a multi-polarized(polycentric) one. Lastly, the integration of the EU railroad system enhances the concentration of economic activity in European metropolitan areas as each metropolitan area tries to develop more competitive space for its rising position in the global urban hierarchical system.

The purpose of this study is to review the relationship between psychological capital and organizational commitment/ innovative behavior, and the moderating effect of organizational support. In order to verify and achieve the purposes mentioned above, questionnaire data were gathered and analysed from 315 professors and teachers of Korea Politechnics Colleges. Multiple regression and multiple hierarchical regression analysis were applied to test the proposed hypotheses: 1) the relationship between psychological capital and organizational commitment, 2) the relationship between psychological capital and innovative behavior, 3) the moderating effect of organizational support on the relationship between psychological capital and organizational commitment, 4) the moderating effect of organizational support on the relationship between psychological capital and innovative behavior. Empirical survey's findings are as follows; First, self-efficacy and optimism appeared to be positively related with organizational commitment, and all psychological capital factors(self-efficacy, resilience and optimism) appeared to be positively related with innovative behavior. Second, organizational support appeared to have moderating effect partly on the relationship between psychological capital and organizational commitment, but it did not have a moderating effect on the relationship between psychological capital and innovative behavior. Self-efficacy and optimism appeared to be more positively related with organizational commitment in higher organizational support situation than in lower organizational support situation.

The histological morphology on the skin of Misgurnus anguillicaudatus was described in the three regions such as dorsal, lateral, occiput and subsequently morphological variations of the skin were monthly observed for a year. The skin consisted of epidermis having epithelial cell, club cell and mucus cell, and dermis of mainly connective tissue fiber, embedded scale and blood capillary. Unicellular mucus cells situated at the epidermis underwent seasonal change in its size, as well as number and amounts of mucus-secreting materials, which they greatly increased in winter, but did not in summer. As it is getting cold, the mucus cells' shape changed from initial spherical to oval or elongated form. Such considerable changes in the mucus cell were particularly most evident in the occiput during winter. Moreover, the dermis largely thickened about 2~3 times in winter than in summer. Based on these results, we discussed function for the mucus on what it mainly acts in nature and information on whether mucus cells' seasonal variations affect on hibernation and cutaneous respiration.
