In recent years, many organizations protect their information resources by investing in information security technology. However, information security threats from insiders have not been reduced. This study proposes a method for reducing information security threats within an organization by mitigating negative information security behaviors of employees. Specifically, the study finds a relationship between information security related role stress and negative behavior and suggests whether organizational justice mitigates role stress. That is, the purpose of the study is to suggest a mechanism between organizational justice, information security related role stress, and negative behavior. Negative behavior consist of avoidance behavior and deviant behavior, and security related role stress consist of role conflict and role ambiguity. Organizational justice consist of distributional justice, procedural justice, and informational justice. The research model is verified through structural equation modeling. After establishing a research model and hypothesis, we develop a survey questionnaire and collect data from 383 employees whose organizations have already implemented security policies. The findings appear that security related role stress increases negative behavior and that organizational justice mitigates role stress. The results of the analysis suggest the direction of organizational strategy for minimizing insider's security-related negative behaviors.

Urban green spaces, as a means to mitigate social problems and environmental risks, are getting more attention in evaluating urban environment. The inequity of green space distribution is becoming a major issue in urban planning and management. This study investigated the characteristics of green space in 3 districts (Jung-gu, Dongdaemun-gu, Seongdong-gu), that are composed of 46 administrative divisions in central Seoul, to analyze the environmental equity of urban green spaces. The correlations between the amount of green space, including the coverage of street trees, and the socioeconomic status of each administrative division were analyzed. To deduce the effects of plant coverage on the urban temperature regime, the relationship between the normalized difference of vegetation index (NDVI) and land surface temperature (LST) was analyzed. The research revealed that the mean NDVI of an administrative division was negatively correlated with the percentage of basic living recipients and disabled people. The LST of a division with low NDVI was higher due to the lack of green coverage. Such environmental inequities were closely related to residential building type, which was strongly affected by the economic status of residents. The LST of an apartment area was $2.0^{\circ}C$ lower than that of single-family houses and multi-housing areas. This is expected as the average NDVI of the apartment area was more than twice as high as the other environments considered in this study. The inequity can be exacerbated without urban planning which is deliberately designed to reduce it.

Objective: The purpose of this study was to investigate the effects of distribution justice, procedural justice, and interactional justice which are the sub-factors of organizational justice on organizational commitment and turnover intention, so as to enhance the quality of childcare and identify the importance of organizational justice. Methods: For the study, the data were collected by measuring the organizational justice, organizational commitment, and turnover intention of 251 teachers working in home day care centers in Busan, Ulsan, and Gyeongnam, and then Pearson's product moment correlation coefficient and regression analysis (stepwise) were conducted. Results: The results are as follows. First, organizational commitment was significantly different in the age in terms of the general background of daily care teachers, as well as the period of service of their current organization, and the turnover intention showed a significant correlation with their salary. Second, the sub-factors of organizational justice and organizational commitment were positively correlated, but turnover intention was negatively correlated. Among them, in terms of organizational commitment, procedural justice and turnover intention were highly correlated with distribution justice. Third, the relative impact of the sub-factors of organizational justice on organizational commitment was high in procedural justice and distribution justice. The relative influence on turnover intention was high in distribution justice and interactional justice. Conclusion/Implications: Therefore, the results of this study indicate that organizational justice is a influential variable on organizational commitment and turnover intention, and suggest that it needs to make efforts to strengthen organizational justice for the operation of home daycare centers.

The primary purpose of this study is to find policy implications by examining the trends in income inequality of the Korean aged and factors contributing to these. For analysis, this study used the 2nd, 5th, 7th and 9th wave of 'Korean Labour and Income Panel Study'. The findings are as follows. First, total income inequality of the elderly rose greatly after 1998 and is decreasing after 2001. Secondly, the Gini coefficient decomposition by income sources shows that earned income was the factor most responsible for the income inequality of the elderly. But its influences of the elderly income inequality is gradually decreasing during analysing periods. Third, assets income and public pensions have a great effects on the elderly income inequality. They increases the income inequality of the elderly households. Forth, interfamily transfer income and public assistance income reduces income inequality of the elderly.

The aim of this study is to examine the effect of transformational leadership of the leader in the wedding industry on the behavior of employees, and also to examine the equity perception of employees on their behavior. As a result of analysis, when the relation between transformational leadership and organizational citizenship behavior was examined, transformational leadership had not effect on behavior of employees. Thus, hypothesis 1 was rejected. As transformational leadership had significant effect on equity perception, hypothesis 2 was adopted. When the relation between equity perception and organizational citizenship behavior was analyzed, equity perception had significant effect on organizational citizenship behavior. Thus, hypothesis 3 was adopted. When the mediating effect of equity perception in the process of the effect of transformational leadership on organizational citizenship behavior as hypothesis 4 was examined, equity perception had partial mediating effects. Thus, hypothesis 4 was partially adopted. Accordingly, the leader in the wedding industry needs to demonstrate transformational leadership in order to promote organizational citizenship behavior of employees and also makes employees to feel impartial treatment and procedural impartiality. Further studies on practical measures of this issue are recommended.

In recent, the primary concern of the forest policy paradigm, which has been mostly focusing on reducing emissions by the effort of afforestation and reforestation, is moving to the REDD activities that are operated by deforestation and forest degradation. In response, the phased studies is going well to visualize performance outcomes of REDD activities. This study brings up the optimum baseline approach for operating the national REDD program by simulating six different baseline approaches broadly used throughout the worldwide, and classified forestry condition for each province in Korea. From this study, we could aware that the carbon credit of HFLD has a low acquisition, but LFMD and LFHD has a high acquisition. Therefore, there are not many reasons for performing REDD activities due to the lack of economical benefits in compared to the devleopment of producing district in HFLD. All kinds of forestry condition, satisfactory baseline approach are needed to enhance the participation and the actuality about REDD program. When evaluating the participation and actuality, the rational decision should be considered as the most appropriate Corridor Approach. This study suggests that the modified Corridor Approach is required for overcoming the weak points, so that we developed the New Corridor Approach which could be easily adopted to Korea environment.

Generational contracts are specified into public pensions based on generational solidarity. The Korean National Pension has been reformed with a focus on generational equity with a narrow meaning related to contribution rate and benefit level. As a result, the Korean National Pension has only emphasized generational equity and not contributed to generational solidarity. We investigate changes in the content of the generational contract and propose to reconstruct generational contract to contribute to solidarity with a more comprehensive perspective. A new social contract by reformed pension system should not concentrate on narrowed generational equity. It should be reconstructed in the direction of enhancing efficacy and the stability of generational solidarity with an emphasis on social sustainability. Investment into the next generation would be one of many policy measures to decrease conflicts around intergenerational redistribution and improve the financial stability of the public pension by creating population structure and labor market changes.

As the need for security of SCADA systems is increasing, significant progress has been made in research on security of control protocol. However, very few security solutions were adapted to legacy SCADA system. The reasons for non-adoption are latency, cost and key management problem. We propose a low latency, economic security Solution to solve these issues. The proposed solution performs security function in data link layer and has minimum overhead to minimize latency. Furthermore, we try to solve the key management problem by providing systematic security keys and key distribution method.

In order to provide a proper mobile internet service, Mobile IP is necessary to support IP mobility. Service network should be a backbone network among mobile agents which support mobility, and MPLS(Multi-protocol Label Switching) of IETF(Internet Engineering Task Force) is being considered as a backbone network because of its speed, scalability and the excellent service capability. MPLS, however, doesn't provide a way to support the mobility of the nodes. In this paper, we present an efficient IMT-2000 network architecture using MPLS to handle Mobile IP. The proposed architecture combines the MPLS label distribution and Mobile IP registration. It doesn't use the layer 3 encapsulation, instead it uses layer 2 for tunneling the data, reduces the size of the header, and it can tunnel the data without delay, which is needed to look up the mobility binding list, as a result.
