Purpose: The Emission Trading Scheme (ETS), which enables structuring emission credits as a financial product, is taking a crucial position of global collaboration against climate change. Previous studies that have covered ETS subjects from the macro perspective contribute to facilitating legal enactment of this scheme. However, they have rarely addressed challenges aligned with issues arising from labor burdens for ETS works from the business perspective. Research Design, data and methodology: This study presents conceptual models that are expected to help design an electronic system. The study model contains four modules: emission allocation, data interface, reduction technology sharing, and emission trading. Two validation approaches, the Analytic Hierarchy Process (AHP) and regression analysis, are applied in confirming the feasibility of the proposed model. Results: This study suggests an IT system methodology to help improvement of the current K-ETS mechanism. In particular, this study addresses effectiveness for real businesses and the adaptability of this mechanism to other nations. Conclusions: The proposed IT platform diagram can contribute to successful operation of ETS by providing multiple benefits to participating companies through in-house allocation mechanisms, the soft-landing of ETS adoption to participating companies through reduction of technology-sharing, group purchases, and transaction costs through the trading system.

Purpose - In this study, the importance of interpersonal relations in the workplace as well as its correlation to satisfaction of social workers were investigated. In addition, effects of organizational culture as well as its implications for human resource management in social welfare workers were outlined. Research design, data, and methodology - A questionnaire was conducted on job satisfaction measured by the Minnesota Job Satisfaction (MSQ) questionnaire. For reliability, the questionnaire was distributed and collected by the self - filling method. From the collected data, reliability analysis, validity analysis (exploratory factor analysis) and multiple regression analysis were used. Cronbach's alpha was used to measure the reliability of the measurement variables and validity analysis was conducted to see if the questionnaires had the same concept as well as SPSS 19.0. Results - The results showed that group culture, hierarchical culture, and rational culture had significant positive effects on job satisfaction. Developmental culture had no effect on the job satisfaction levels. Conclusions - It is important to maintain the hierarchy in order to improve the efficiency of social welfare organizations, but social welfare organizations must accept external opinions and actively listen to the opinions of the employees in the organization.

Currently, the investment on Research and Development(R&D) for defense core technology is continuously increasing to maintain advanced country's R&D level. In accordance with this trend, the national defense R&D investment management system is being more strengthening, and importance of performance evaluation is being emphasized more and more. However, the existing indicators of performance evaluation for defense core technology R&D is limited in efficient management because of the qualitative evaluation items and subjective allocation of points. In this paper, we developed a novel indicator for defense core technology R&D performance evaluation through domestic and foreign related literature and inquiry, brainstorming, and analysis techniques by Stepwise Multiple linear Regression(SMR) and Analytic Hierarchy Process(AHP). And we verified effectiveness of proposed indicators of performance evaluation by comparing with the existing evaluation indicators. Our proposed indicators for performance evaluation will create superiority performance on defense R&D fields.

Purpose : This study aimed to identify the factors influencing the professional quality of life of intensive care unit (ICU) nurses working in university hospitals. Methods : A survey was conducted on 171 ICU nurses in university hospitals in B City, South Korea. This study used the Professional Quality of Life instrument, which consists of three subscales, namely, compassion satisfaction, burnout, and secondary traumatic stress. Data were analyzed using stepwise multiple regression analysis. Results : Compassion satisfaction was influenced by resilience, ICU job satisfaction, and innovation-oriented culture, and these variables explained 37.1% of the variance in compassion satisfaction. Burnout was influenced by resilience, a hierarchy-oriented culture, and ICU job satisfaction, and these variables explained 42.9% of the variance in burnout. Secondary traumatic stress was influenced by a task-oriented culture and resilience, and these variables explained 12.5% of the variance in secondary traumatic stress. Conclusion : These findings suggest the importance of improving resilience and job satisfaction to enhance the professional quality of life in ICU nurses. Moreover, creating an innovation-oriented culture rather than a hierarchical and task-oriented culture can effectively improve the professional quality of life of ICU nurses.

In this study, we investigated the relationship between friendship level within a hospital organization and job satisfaction, organizational commitment and job stress. Focusing on the hierarchy and occupation of a hospital, different from previous introductory studies. As a study tool, structured questionnaire were devised and used. The subjects were nurses, administrators and medical technicians who worked at 17 tertiary hospitals in Seoul and Kyongin area. To analyze the data, we conducted frequency analysis, t-test, one-way ANOVA, two-way ANOVA and multiple regression analysis.The main results of our study can be summarized as followings:Firstly, seen from the viewpoint of social demographic characteristics, on the whole friendship level with fellows is the highest, and then that with subordinates and that with bosses the lowest. Secondly, the friendship level with bosses, subordinates and fellows had a significant relationship with job satisfaction, organizational commitment and job stress, though there were some differences among them. In case of junior managers, the friendship level with fellows had a significant relationship with job satisfaction and organizational commitment; in case of middle managers, the friendship level with fellows had significant relationship with job satisfaction. We found that the friendship level with the bosses had a deeper relationship with job satisfaction, organizational commitment and job stress as we went down the hierarchy. Thirdly, analyzing the differences between occupation, administrators and medical technicians had relatively higher significant relationship with the friendship level with bosses than nurses in job satisfaction, organizational commitment and job stress. High friendship level with the bosses influenced job satisfaction significantly for the nurse; yet, in case of administrators and medical technicians, the friendship level with bosses influenced all of job satisfaction, organizational commitment and job stress. Based on our study, we recommend facilitating friendly relationship between the bosses and the subordinates in order to enhance job satisfaction, organizational commitment and job related stress reduction.

VoIP (Voice over Internet Protocol) is a technology of transmitting and receiving voice and data over the Internet network. As the telecommunication industry is moving toward All-IP environment with growth of broadband Internet, the technology is becoming more important. Although the early VoIP services failed to gain popularity because of problems such as low QoS (Quality of Service) and inability to receive calls as the phone number could not be assigned, they are currently established as the alternative service to the conventional wired telephone due to low costs and active marketing by carriers. However, VoIP is vulnerable to eavesdropping and DDoS (Distributed Denial of Service) attack due to its nature of using the Internet. To counter the VoIP security threats efficiently, it is necessary to develop the criterion or the model for estimating the information security level of VoIP service providers. In this study, we developed reasonable security indicators through questionnaire study and statistical approach. To achieve this, we made use of 50 items from VoIP security checklists and verified the suitability and validity of the assessed items through Multiple Regression Analysis (MRA) using SPSS 18.0. As a result, we drew 23 indicators and calculate the weight of each indicators using Analytic Hierarchy Process (AHP). The proposed indicators in this study will provide feasible and reliable data to the individual and enterprise VoIP users as well as the reference data for VoIP service providers to establish the information security policy.
