While the role of local community is getting important in reducing greenhouse gases, current financial supports have not considered these efforts. Instead, development activities have been the only basis of fiscal distribution, which have led to unsustainable development. In this context, this paper analyzes the emission and absorb of air pollutants by local districts in Daegu Metropolitan city and constructs an empirical energy database for local energy use and environmental emissions. Based on the data, it prioritized environmental contribution by region through using MCDM methods, that include maximin & maximax method, simple additive weighting (SAW) and hierarchical additive weighting method (HAW). This concludes the possibility of policy methodology through which we can input environmental variables in distributing local budget.

This study aims to evaluate the effectiveness of the dual-punishment system by analysis of the financial performance of pharmaceutical companies before and after introduction of the dual-punishment system. This study analyzed the business performance of 136 pharmaceutical companies from 2009 to 2011. The results from paired t-tests found that sales, operating cost, and EBITDA showed significant differences in performance, and, according to the variance analysis, the five groups obtained through a hierarchical cluster analysis differed from each other in sales, operating cost, EBITDA, and research and development cost. Differences in financial performance among the groups seem to be related to the strategy for response to the regulation. The introduction of the dual-punishment system is generally acknowledged to have had positive effects on the pharmaceutical industry. However, some companies appear to be continuing kickback practices.

Numerous solution methods for scheduling problems such as part dispatching problem, operation sequence problem have been suggested as a means to be embedded in hierarchical or centralized shop floor control. Under the preceding control philosophies, however, response to changes in the shop floor status is quite slow and timely decision is sometimes impossible. Moreover, the control software becomes too large and it is almost impossible to modify the control software when the configuration of the shop floor changes. In agile manufacturing which emerged recently to cope with quick response and easy modifiability when unexpected changes occur, a new control policy is needed. CSCW[Computer Supported Cooperative Work] based shop floor control casts a different view on scheduling problems. Decisions are made locally when requested and useful information is scattered among agents for its efficient use. Adaptation is easy because agents are -'plug compatible or portable. In this paper, scheduling problems occurring under CSCW based shop floor control are identified and characterized. Traditional scheduling problems are reviewed from the CSCW viewpoint. All the control entities involved in the shop floor can be found and used to defined agents. With these entities and CSCW concept, possible scheduling problems are identified.

The study aims to investigate methods for companies to contribute to not only social and national developments, but also on the promotion of individuals and companies by re-examining the various phenomena that define companies. The study examines the relationship between subordinate factors of social responsibility activities and job performances as well as the role of CEOs in showing authentic leadership and meaningfulness of work. A total of 312 valid questionnaires were obtained, and hypotheses were tested using regression analysis, hierarchical regression analysis, and 3-way interactions. The results suggest that corporate social responsibility activities not only enhanced the performance of the members, but also confirmed the importance of the authentic leadership of the CEO. Additionally, the role of the members in the company also showed to play a very significant role in a company's developments. The results also show that the CEO and members need to make efforts to increase ethics as well as gain more competitiveness and improve their reputation by promoting their sense of calling and feeling of compassion in the workplace. In other words, the members of the high-ranking book and the members of the relatively low position will have different degrees of information transfer and evaluation of the company policy may be different.

Purpose - The purpose of this study was to analyze the effects of education & training and organizational culture on job satisfaction and organizational commitment and then examine the difference that would appear depending on the job title in the case of Korean employees in the manufacturing industry. Research design, data, and methodology - Our sample consisted of 1,013 administrative employees in the manufacturing industry with data extracted from the 4th Human Capital Corporate Panel (2011) survey. Descriptive statistics and multiple regression analysis were conducted. Results - Results showed that education & training had positive effect only on job satisfaction while organizational culture had positive effect on both job satisfaction and organizational commitment. Components under education & training (duration of the formal learning, efficacy of formal learning and efficacy of informal learning) and organizational culture (equity, communication, talent recognition, innovation) that were found to be affecting job satisfaction and organizational commitment revealed to be different depending on the hierarchical position of the employee. Conclusions - Different approach and policy for each group of job title could be considered in order to increase job satisfaction and enhance organizational commitment of the employees.

We analyzed the introduction factor of ASP-based information system on the order of importance using AHP techniques. We classified the introduction factors from previous studies into three categories : Organizational factors revealed organizational factors to be of highest importance, followed by environmental and Quality factors. The analysis on both primary and secondary hierarchical factors revealed CEO support as the most important, followed by IT capability, provider reliability, and cost-cutting expectation.

Applications have evolved with the evolution of smartphones, and the search structure is changing as well. In this study, we searched through various cases of cross platform and found out the search pattern and suggested correct usage method accordingly. As a result, the search structure for cross platform can be divided into persistent navigation, temporary navigation, and auxiliary navigation. Persistent navigation is available in a hierarchical structure using springboards, lists, galleries, and top menus. Temporary navigation can take advantage of drawers, toggle menus, and pie menus, while secondary navigation can provide the same experience across platforms using an accordion menu or scrolling.

Constructing an effective production control policy is the most important issue in wafer fabrication factories. Most of researches focus on the input regulations of wafer fabrication. Although many of these policies have been proven to be effective for wafer fabrication manufacturing, in practical, there is a need to help operators decide which lots should be pulled in the right time and to develop a systematic way to alleviate the long queues at the bottleneck workstation. The purpose of this study is to construct a photolithography workstation dispatching rule (PADR). This dispatching rule considers several characteristics of wafer fabrication and influential factors. Then utilize the weights and threshold values to design a hierarchical priority rule. A simulation model is also constructed to demonstrate the effect of the PADR dispatching rule. The PADR performs better in throughput, yield rate, and mean cycle time than FIFO (First-In-First-Out) and SPT (Shortest Process Time).

This study investigated social determinants and their interaction effects on the health of school-aged children in diverse environmental factors pertaining to the individual, family, and peers from an ecological systematic perspective. Data were drawn from the first wave of the Korean Children and Youth Panel Survey (KCYPS) developed by the National Youth Policy Institute and conducted in 2010. Data were analyzed by descriptive statistics, Cronbach ${\alpha}$, correlation, and hierarchical regression analysis using SPSS ver. 18. The results from this study showed that sex and age were related to the health of school-aged children, as social determinants. Self-rated levels of the health of boys and younger children were more positive than girls and older children; in addition, levels of self-resilience, satisfaction of peer relation, and parenting rearing attitude were found to have a positive impact on self-rated levels of the health of school-aged children as protective factors. Especially, according to the result of interaction analysis between factors, self-resilience, and parenting rearing attitude were moderators of the effects on between sex and household income and self-rated level of the health of school-aged children respectively. The findings from this study suggested the need to expand the social intervention range to improve school-aged children's health.

Recent years have witnessed an increasing number of alternative school students in Korea. However, few studies have empirically examined these students' school adjustment and peer relationship skills. To address this gap in the literature, this study examines the effects of individual characteristics, family characteristics and peer relationship skills on these students' school adjustment. Four aspects of school adjustment were measured as dependent variables. These four aspects included peer relationship adjustment, relationships with teachers, school environment adjustment, and schoolwork attitude adjustment. The peer relationship skills included three components, namely initiative, mutual closeness, and order awareness. Data were collected from 323 alternative middle and high school students through a structured questionnaire. The statistical analysis methods included descriptive statistics and a hierarchical regression analysis using SPSS WIN 19.0. According to the results, peer relationship skills as well as family background characteristics, including the age of the father, the education level of the father, the family economic level, and the number of close family members, had significant effects on school adjustment. The results highlight the importance of peer relationship skills for these students' successful school adjustment and have important policy and theoretical implications.
