Ambidexterity in organizations, in general, is interpreted as flexibility that enables organizational innovation, which is important for survival in a competitive market. It applies to individual workers as well since the ambidexterity of explorational and exploitational IS use will enable the flexible transition between dynamic and operational work, and hence, increase the work performance. The current study will therefore investigate the individual levels of exploratory and exploitative IS use, as well as the complementary relationship between exploratory and exploitative IS use. In a third step, the differential influence of IS on work performance will be evaluated. The current study validated that complementary fit of IS use exploration and IS use exploitation increases performance. Polynomial regression and surface analysis are used to validate the incongruence of IS use pattern. They showed that the incongruence of ambidexterity is composed of two types of divergent vs. convergent ambidexterity which depends on the type of work that need dynamic or operational capability.

This study established the relationship between job stress and burn-out syndrome of firefighters. The research targets were 582 firefighters who worked at five fire stations in the D metropolitan city. The survey was conducted using a self-administered questionnaire during the period from July 1st 2019 to September 30, 2019. On the correlation analysis, burn-out showed a significant positive correlation with job stress. On the results of the logistic regression anaylsis, the risk ratio of high levels of burn-out was significantly higher in the very high stress groups than that in the groups with low job stress. According to the multiple regression analysis, the factors having an influence on burn-out were gender, age, the specific level of job career, shift work, the physical burden of work, the sense of satisfaction with the work, consideration for quitting the job and job stress. These findings suggest that the job stress of firefighters is closely related to burn-out. This demands the development and implementation of programs that can properly control and curb the factors of job-stress.

Epidemiological studies showed that high trans-fat consumption is closely associated with getting the risks of cardiovascular disease. The objective of this study was to produce trans-free fat through lipase-catalyzed interesterification, as a substitute for the cream margarine commonly used in industry. Optimum conditions for interesterification in a packed bed enzyme bioreactor (PBEB) were determined using response surface methodology (RSM) based on central composite design. Three kinds of reaction variables were chosen, such as substrate flow rate (0.4-1.2 mL/min), reaction temperature (60-70$^{\circ}C$), and ratio of fully hydrogenated canola oil (FHCO, 35-45%) to evaluate their effects on the degree of interesterification. Optimum conditions from the standpoint of solid fat content (SFC) were found to be as follows: 0.4 mL/min flow rate, 64.7$^{\circ}C$ reaction temperate, and 42.8% (w/w) ratio of FHCO, respectively. The half-life of immobilized lipase in PBEB with two stages at 60$^{\circ}C$ ($1^{st}$ stage) and 55$^{\circ}C$ ($2^{nd}$ stage) was about more than 30 days as estimated by extrapolating the incubation time course of tristearoyl glycerol (TS) conversion, whereas the half-life of the enzyme in PBEB with single stage at 65$^{\circ}C$ was only about 15 days. Finally, the results from SFC analysis suggest that trans-free fat produced in this study seems to be a suitable substitute for the cream margarine commonly used in industry.

This study was performed to predict spatial change of future forestland area in South Korea at regional level for supporting forest-related plans established by local governments. In the study, land use was classified to three types which are forestland, agricultural land, and urban and other lands. A logistic regression model was developed using transitional interaction between each land use type and topographical factors, land use restriction factors, socioeconomic indices, and development infrastructures. In this model, change probability from a target land use type to other land use types was estimated using raster dataset(30m×30m) for each variable. With priority order map based on the probability of land use change, the total annual amount of land use change was allocated to the cells in the order of the highest transition potential for the spatial analysis. In results, it was found that slope degree and slope standard value by the local government were the main factors affecting the probability of change from forestland to urban and other land. Also, forestland was more likely to change to urban and other land in the conditions of a more gentle slope, lower slope criterion allowed to developed, and higher land price and population density. Consequently, it was predicted that forestland area would decrease by 2027 due to the change from forestland to urban and others, especially in metropolitan and major cities, and that forestland area would increase between 2028 and 2050 in the most local provincial cities except Seoul, Gyeonggi-do, and Jeju Island due to locality extinction with decline in population. Thus, local government is required to set an adequate forestland use criterion for balanced development, reasonable use and conservation, and to establish the regional forest strategies and policies considering the future land use change trends.

This study examined characteristics and usefulness of middle-aged and older people's vocational training participation. Among sub-age groups categorized by the position in career cycle and the employability, 61~68 year old group(after retirement age group) had the biggest difficulties on the training including computer-based training and showed the lowest employment result compared to other sub age groups; major career(30~45), career transition preparation(46~52), career transition(53~60). However, the career transition age group utilized vocational training in the aspect of career search and the after-retirement age group in the aspect of preparation for older age and hobby. On the other hand, factors such as career adaptability and perceived education difficulties affected on the training usefulness in the aspects of career search and preparation for older age and hobby while perceived career barriers, career relevancy and relationship ability affected on the employment result. Based on these findings, this study suggests that vocational training provide more suited course for the boundaryless career seekers and include relationship enforcement and positive attitude development to overcome perceived career barriers for middle-aged and older people.

The study started with the question, "Is Japan's normalization of nationalization a return to militarism?" Therefore, in order to analyze this, the characteristics of the international system after the inauguration of the Japanese Empire during World War I and World War II and the Abe's 2nd Cabinet in contemporary Japan were compared. Through this, there were some differences in the characteristics of the international system of the two periods, and as a result, it was intended to derive the differences between the two examples. During the prewar period of World War I, the militaristic Japanese Empire suffered great damage from the national pride of being the only power in Asia through the Paris Enhancement Conference, the Washington Navy Treaty, and the London Navy Treaty. However, the Western powers with colonies in Asia still existed in the region, so it was not possible to turn them into immediate power expansion. Meanwhile, World War II broke out in Europe. As a result, the Western powers had to focus on the whole of Europe, and the militaristic Japanese empire became a regional hegemony without missing the international system characteristic of "the hegemony." Unlike in the past militarism, Japan's case of pursuing common nationalization since 2012 has been carried out in the order of Northeast Asia in the composition of the "cold war" new cold war. In particular, Japan is attempting to transform itself into a normal state to strengthen the US-Japan alliance on a self-reliant level due to the lack of quantitative military power compared to the neighboring countries.
