This study aims to investigate and practically examine the effect of environmental qualifications based on the theoretical background on the area. First, the economic effect of the acquisition of the qualifications was to be studied from the viewpoints of individuals and from an actual analysis on it, its effect was to be proved. Second, its non-economic effect was to be proved from the same way as the first analysis. On the basis of theoretical background, a study model was formulated in a way that the effect of qualifications in individuals side was divided into an economic effect (wage, employment, promotion, job-switching) and non-economic effect (self-development, self-efficiency, satisfaction on the job, ability to cope with the advancement of technology, job performance, signal effect, the settlement of uneasiness at unemployment). Then, survey was carried out with questions designed in accordance with this model. The hypotheses were proved as the following. First, for hypothesis 1(Environmental qualifications will bring up positive impacts on an individuals economic effect), environmental qualifications was shown to have positive impacts on wage, job-switching in personal economic effect. But, no personal economic effect appeared for employment and promotion. Second, for hypothesis 2(Environmental qualifications will bring up positive impacts on an individuals non-economic effect), environmental qualifications appeared to have positive impacts on self-efficiency, ability to cope with the advancement of technology, job performance and signal effect. Besides, no impact was shown in satisfaction on the job and the settlement of uneasiness at unemployment and self-development.

This paper attempts to understand the factors that affect the social and economic performance of social venture and thereby obtain practical and useful implications. We analyze how such factors as social entrepreneurship, management competency, and organizational culture affect economic and social performance of 185 social venture in korea. In addition, we examine how government support may moderate the relationship of each variable. We find that innovativeness, proactiveness, risk-taking and social value orientation positively affect economic performance, whereas innovativeness, proactiveness and social value orientation can enhance social performance. We also learn that social entrepreneur's competency can have a direct effect on the enterprise's profitability, while organizational culture seems to affect performance of the companies only slightly. Government support is shown moderate effect of social entrepreneurship, competency, and organizational culture on the company's performance. Interestingly, our findings indicate that raising competency of social enterprise can be more effective than government support for enhancing performance of companies. Lastly, social venture's economic performance is shown to affect its social performance.

PURPOSES : This study aimed to analyze the experimental and numerical behavior of warm mix asphalt pavement prepared using steel slag and RAP and to conduct economic analysis of pavement construction. METHODS : For developing high performance asphalt pavement, we performed three evaluations: fundamental analysis, experimental testing, and 3D finite element analysis. In particular, 3D finite element analysis was conducted on several pavement structures by adopting the results of experimental tests. RESULTS : Through the various evaluations, it was established that steel slag was effective for use as asphalt mixture aggregate. Moreover, asphalt mixture constituting steel slag and RAP demonstrated higher performance behavior compared with conventionally used asphalt mixture. Furthermore, based on the 3D FE modeling, we established that the developed asphalt pavement constituting steel slag and RAP can be utilized for thin layer pavement with comparable performance behavior. CONCLUSIONS :Warm mix asphalt pavement prepared using steel slag and RAP is more competitive and economic compared to hot-mix asphalt pavement. Moreover, it can be applied for preparing thin layer asphalt pavements with reasonable performance. The developed warm mix asphalt pavement prepared using steel slag and RAP can be an alternative pavement type with competitive performance based on the reasonable economic benefit it provides.

Scientific and technological performances (e.g., patents and publications) made through R&D play a pivotal role for national economic growth. National governments encourage academia-industry cooperation and thereby pursue continuous development of science technology and innovation. Increasing R&D-related investments and manpower are crucial for national industrial development, but evidence of poor performance in business performance, efficiency, and effectiveness has recently been found in Korea. This study evaluates performance efficiency of the 6T sector (Information Technology, Bio Technology, Nano Technology, Space Technology, Environment Technology, Culture Technology), which is considered a high-potential promising industry for the next generation growth and currently occupies two thirds of the national R&D projects. The study measures the relative efficiency of R&D in a comparative perspective by employing the Data Envelopment Analysis (DEA) method. The result reveals overall low efficiency in basic R&D (0.2112), applied R&D (0.2083), development R&D (0.2638), and others (0.0641), confirming that economic performance and efficiency were relatively poor compared to production efficiency. Efficient R&D needs policy makers to create strategies that can increase overall efficiency by improving productivity performance and quality while increasing economic performance.

Purpose - As globalization progresses, complexity also increases, and various factors that threaten port functions are emerging. Accordingly, the demand for port security to prevent the crisis and resilience that quickly recovers its original function after the crisis is also increasing in port operations. However, few studies have examined how to ensure the port security and how the resilience affects operation performance of port and sustainability performance as well. So the study aims to find out how port security affects port resilience and port operational performance, and consequently, this two factors affect socioeconomic and environmental sustainability performance respectively and synthetically. Design/methodology - Confirmatory Factor Analysis (CFA) was first performed to determine the validity of the factors of model and hypothesis test was performed using Structural Equation Model (SEM) to analyze the Port Performance Model, which show the perception logic among port security level, port resilience, operation performance, and sustainability performance. In order to empirically analyze this model, total 264 respondents from port security operators, shipping companies in South Korea were surveyed. Findings - As result of SEM, First, port security level positively affected the resilience (H1) and cargo operational performance (H2) but not in both of the sustainability performances (H3, H4). Second, resilience positively affected only cargo operational performance (H5) and socio-economic sustainability performance (H7). Last, cargo operation performance positively affects the both of sustainability performances (H8, H9). Originality/value - It was confirmed that port security could improve cargo operational performance through ensuring port resilience and eventually increase the socio-economic sustainability. Therefore the study implies that careful integration and management of port security, port resilience, and sustainability are required, along with compromise on sustainable development goals in the social, economic, and environmental area among all stakeholders.

The purpose of this study is to analyze the factors affecting cooperation between industry and public research institutes, in addition to the effects of cooperation between them; on technological and economic performance of firms. Based on existing research relating to the factors affecting industry-university-research institutes cooperation and the relationship between them and firm performance, this study selected the competence of government-funded research institutes, R&D capabilities and organizational characteristics of firms, and support of government and local governments; as factors influencing cooperation between industry and public research institutes. This study sets seven hypotheses on the relationship between the factors promoting industry-public research institute cooperation, technological performance and economic performance. A questionnaire survey was used to collect data for hypothesis testing and 116 questionnaires were completed and used in this research. The PLS-MGA was used as a method for hypothesis testing. In the analysis results, we found that the competence of government-funded research institutes, organizational characteristics of firms, and the support of government and local governments have a positive impact on cooperation between industry and public research institutes. We also found that the collaboration between industry and public research institutes, positively affects firms' technological performance. In addition, we found that the technological performance of a firm, positively affects a firms' economic performance. On the other hand, firms' R&D capabilities have no significant effect on cooperation between industry and public research institutes, and industry-public research institute cooperation does not directly affect the economic performance of firms.

This study investigates the voluntary corporate disclosure of environmental information via stand-alone environmental reports or company web-sites. Quality of disclosure was assessed using the content analysis index proposed by Clarkson et al. (2008) based on GRI guidelines. Descriptive statistics on disclosure scores by category suggest that the level of disclosure is low relative to the expectation implied by the GRI reporting guidelines, and points to the need for improvement in the future. Specific areas where improvement is required include the disclosure of environmental performance indicators. Corporate environmental performance was measured in terms of the percentage of toxic wastes that was treated or processed by each firm and economic performance, by industry-adjusted annual return, which was subject to a series of association tests designed to explore the interrelations among environmental disclosure, environmental performance, and economic performance. The individual equation approach based on OLS procedures suggests a positive association between environmental performance and the level of discretionary environmental disclosures, which is not the case between environmental and economic performance. An integrated analysis using simultaneous equations approach does not indicate any significant relationships among three constructs, suggesting the lack of endogeneity, inconsistent with Al-Tuwaijri et al. (2004). Additional analysis assesses the level of environmental disclosure made in footnotes to the audited annual reports, which suggests that the quality of disclosure is very low and that footnote disclosure does not serve as a meaningful channel for the provision of corporate environmental information.

The purposes of this study are to examine the economic conditions and parenting of custodial fathers/mothers and to explain their impacts on the children's social adjustment after divorce. A total of 185 custodial parents divorced within the last 5 years completed a structured questionnaire. Children's social adjustment was the dependent variable in this study and was defined as their school performance and behavior problems. Results show that compared with divorced custodial fathers, divorced custodial mothers demonstrate more effective parenting, but there were no differences in economic conditions between them. In addition, children in single-father divorced families have lower school grades and more behavior problems than those in single-mother divorced families. Results also indicate that the economic conditions and parenting have different effects for children across family type. For children raised with a custodial father in divorced families, the economic conditions and the divorce duration are associated with lower school grades and behavior problems. For children with a custodial mother, however, the effective of parenting and the children's age have significant effects on the children's social adjustment after the parent divorced. Based on these results, this study proposes strategies for the improvement of children's adjustment in divorced families.

The purpose of the study is carried out volume optimization of a combined system consisting of an LNT and SCR catalysts from the standpoint of its economic feasibility and de-NOx performance. Under the rich air-fuel ratio conditions for 5s (${\Phi}$=1.1), CO, $H_2$ and THC were generated at levels of 4%, 1.2% and $110ppmC_1$, respectively. The NOx conversion of the 1+1 combination was 5% lower than that of the 1.5+0.5 combination, however the reduced volume of the LNT catalyst decreased the total cost by about 6%. Therefore, the optimal volume ratio of the LNT and SCR catalysts was found to be the 1+1 catalyst combination, which has the highest total score in the terms of an economic feasibility and the NOx performance.
