환경의 가치, 특히 물의 가치는 시대와 함께 변화하고 있다. 그동안 국내 하천관리는 환경적 측면보다는 이수와 치수에 보다 초점이 맞춰져 있어, 하천 고유의 수생태계 서비스기능 유지에 필요한 용수의 확보에 정책적인 배려가 부족하였다. 그러나 최근 소득수준이 향상되고 환경개선에 대한 관심이 늘어나면서 물관리에 있어 이용뿐만 아니라 환경측면을 고려한 지속가능한 하천관리에 대한 정책적 관심이 높아지고 있다. 이에 하천 수생태에 대한 정책 역시 과거보다 강화되고 있는 추세이며, 최근 물환경보전법 공포를 통해 수생태건강성 유지를 위한 환경생태유량에 대한 법적 근거가 마련된 바 있다. 실질적인 환경생태유량 공급 정책방안 마련을 위해 환경생태유량 공급이 하천 수생태에 주는 효과에 대한 편익 정보를 산정해볼 필요가 있다. 이에 본 연구에서는 환경생태유량 공급효과에 대한 편익을 산정해 보았으며, 이를 위하여 대표적인 비시장재화 가치평가법인 선택실험법을 적용하였다. 한편 환경생태유량 공급효과에 대한 많은 연구에서는 환경생태유량 공급효과를 하천의 주요 어종 관련 지표를 통해 나타내고 있다. 이에 본 연구에서도 환경생태유량 공급에 대한 편익산정시 하천고유어종 변화, 하천 어종 수 변화, 외래어종 변화의 3가지 속성에 대한 한계지불의사액을 추정하였다. 본 연구결과는 환경개선을 위한 정책수행, 특히 수생태계 환경개선을 위한 정책결정시 기초자료로 활용될 수 있을 것으로 판단된다.

생산자 폐기 책임 규제 강화로 인하여, 제조업 영역이 제품 제조(BOL) 뿐만 아니라 사용, 보수(MOL)와 폐기(EOL)까지 확장 수명주기로 확대 되고 있다. 또한 EOL상에서 개별 제품에 대한 제품 복원 관리 시스템 (PRMS: Product Recovery Management System)에 관한 연구가 활발히 진행 되고 있다. 그러나 BOL, MOL과 EOL간의 정보 단절 문제, MOL상의 정보를 저장하고 사용할 수 없었던 문제는 EOL관리의 자동화를 저해한 큰 요인이다. 최근 유비쿼터스 기술의 발달로 개별 제품 추적이 가능해 졌지만, EOC 등의 식별부호(ID)만으로는 PRMS에 필요한 제품 정보를 얻을 수 없다. 본 논문에서는 제품 ID로부터 MOL상의 정보를 연결하고, 국제표준 기반 정보모델을 이용하는 PRMS를 개발한다. 이를 위해: (1) PRMS에 필요한 정보를 국제표준(ISO10303-239 등)을 기반으로 모델링하고, (2) 제품 ID를 통해 MOL상의 정보를 수집하여 제품 복원에 대한 의사결정을 수행할 수 있는 PRMS를 설계하고, (3) 시제품 구현을 통해 제안된 데이터 모델 및 시스템의 유효성을 검증한다.

운전자의 인지 능력을 충분히 고려하지 않은 도로 교통 표지판은 운전 상황에서 순간적인 의사 결정을 어력베 하여 교통사고의 가능성을 증가 시킬 수 있으므로 이에 대한 개선책이 시급하다 하겠다. 그러므로 본 연구에서는 수도권 도로 교통 표지판의 인지적 문제를 설문 조사와 현장 조사를 통하여 구체적으로 분 석하고 이에따른 개선안을 제시하였다. 이를 위해, 서울 시내의 사고 다발 지역을 중심으로 교차로 표지 판의 인지공학적 결함을 면밀히 분석하였고, 1997년 표지판 개정안의 설계 원칙에 대한 인지적 문제점을 도출하였다. 그 중, 교차로의 방향 표지, 방향 유도 표지에 나타난 정보 처리 과정의 문제점 및 노면 표지 의 설계가 운전자의 인지적 혼돈을 유발시킬 수 있다는 가정하에 이에 대한 모의 실험을 실시 하였다. 24명 의 피설험자를 대상으로, 개선된 표지판과 현 표지판을 모의 운전 상황에 따라 간헐적으로 컴퓨터 화면을 통해 관측하게 한 후 인지된 내용의 정확도와 반응 시간을 비교하여 분석하였다. 그 결과에 따라 기존 노면 표지의 형태를 개선하고, 방향 예고 표지판과 방향 표지판의 인지적 구별을 명확하게 하는 것이 운전자에게는 정확하고 신속한 의사 결정을 하게 한다는 것을 발견 하고 이에 대한 원칙을 제시하였다. 결론적으로 표지판의 설계와 설치에 있어 행정적인 지원과 인지적인 요인에 대한 고려가 된다면 표지판의 오독으로 인한 교통 사고를 줄여 나가는데 기여할 것으로 기대된다.

Compared with other industries, construction industry shows a higher rate of death accidents and recently companies' legal responsibilities are to be increasingly enforced. The trend causes tremendous concerns for construction firms and increases the importance of forecasting and pro-actively managing death accidents in construction fields. The objective of the study is to develop a predictive analytics model for forecasting death accidents in building projects based on a decision tree technique, which enables to forecast the probabilities of death accidents by trade. The use of the model helps to decrease risks of legal punishments and to assist the safe execution of building projects by forecasting and pro-actively managing death accidents.

This study identified the characteristics of video contents related to waste cycle in Korean social media. The contents of broadcasting companies were the most popular among production entities, and mainly current affairs contents and educational contents were popular. Among the solutions to recycle wastes, 'Improvement of systems and policies' was predominantly covered in the video as solutions to the waste circulation problems. 'Broadcasting companies', 'local governments', 'non-profit private organizations' and 'central administrative agencies' actively used the social media to deliver solutions and engage consumers. However, very few contents were produced by companies that are socially responsible for waste. The results of this study show the importance of communication-oriented, public-friendly content development in the process of video production related to waste cycle. These are expected to be useful guidelines for decision-making supporting the development and improvement of related systems and policies.

This study aims to verify culture-universal invariances and culture-particular differences in the relationship of job stress, flourishing, and job engagement. For this purpose, we selected a global korean company having a local corporation in China in order to minimize the influence of organizational factor and a self-report questionnaire survey was conducted by 141 personnels of head office and 107 personnels of chinese branch. At first, the mediating effect of flourishing on the relationship between job stress and job engagement was significant for both korean and chinese personnel. Second, regression analyses were conducted in order to demonstrate influence of detailed job stress on flourishing and job engagement. As for flourishing, decision making and responsibility factor was significant for korean personnel, and lack of social support factor and job characteristic factor were significant for chinese personnel. Regarding job engagement, lack of social support factor and job characteristic factor were significant for both two samples and decision making and responsibility factor was significant for korean personnel whereas non-significant for chinese personnel. The results could give a meaningful perspectives to companies interested in extending their business abroad. Finally, implications and limitations of the study and suggestions for future research were discussed.

As the society's expectations of business have drastically amplified in recent years, an increasing number of companies have devoted their resources and managerial attention to corporate social responsibility. However, little information bas been reported on consumers' expectations on social responsibility of restaurant companies. This research studied the consumer's perception on the socially responsible business practices of restaurant companies. The research also investigated if the customer's expectations differ based on the types of restaurants. Overall, it was found that the consumers strongly feel the necessities of restaurants' socially responsible activities and publicity of those activities (4.08 and 4.05, respectively, out of 5). They also responded that the socially responsible behaviors of restaurants somewhat affect their purchase decisions (3.74 out of 5). As a result of a principle component analysis, five types of socially responsible activities(i.e., philanthropic responsibility, economic responsibility, community responsibility, environmental protection responsibility, and consumer protection responsibility) were extracted. In addition, the results showed that the consumer's expectations toward socially responsible activities of restaurants differ based on the types of restaurants (multivariate F=4.616, p=0.000).

It is necessary for undergraduate students whose citizenship reaches a maturity stage to recognize the importance of citizen participation in social issues related to science and technology and to be able to make meaningful use of citizens' rights and responsibilities. Therefore, in order to understand the actual status of undergraduate students' perceptions and practice capacity for citizen participation in science and technology, university students were selected from the department of arts physical studies (33 cases), humanities social studies (62 cases), and science engineering studies (67 cases) at D university in Gyeonggi province. Then, we investigated the scientific technology and society's interaction oriented by citizen participation, responsible decision-making ability, and the effectiveness of the social issue by scientific technology. Analyses of the results reveal that the overall perception level of the students about the interaction between scientific technology and society was high according to department of the arts physical studies, humanities social studies, science engineering studies, in that order, but the scores were not all in average. Therefore, it was found that the current undergraduate students lacked a deep understanding of the interaction between scientific technology and society regardless of the major field. In addition, the students' perception on citizen participation in the interaction between scientific technology and society was found to be problematic regardless of the major field. In responsible decision-making ability, undergraduate students were found to have difficulties in selecting the best alternative in terms of individual beliefs and welfare of others and formulating the action strategies. In addition, the self-confidence of the students about knowledge, skill, and capacity for action related science and technology in the effectiveness of the social issue by scientific technology was very low regardless of major field. We discussed educational implications of these findings.

This study examines how labor unions change in the 21st centry and what is needed for successful transformation of Korean labor union. The study identifies four major driving forces of change in union's role. They are changes in industrial and occupational structures, utilization of information technology, labor substitution, and changing attitude of workers. The effects are decrease in union membership, shrinking coverage of bargaining, weakening voice mechanism, and representation. Thus, labor unions in the 21st centry transform themselves into service union, individual representation system, and worker participation model. Korean labor union, with its current reputation of militant unionism, needs to transform into above mentioned model. Two keys for the change are market competition and family unionism.

In medical litigation, there are various cases where a doctor's 'explanation' of a patient becomes problematic. Medical explanations and guidance are required from the doctor, starting from the beginning of diagnosis, through treatment processes such as surgery, when hospitalization is necessary for treatment, during hospitalization, upon discharge, and after discharge. Furthermore, notification from the doctor or medical institution may be requested regarding the economic costs that will be incurred due to medical treatment. South Korea's judiciary has been developing legal principles regarding such doctor's explanations by distinguishing between explanations for obtaining consent for medical treatment and medical explanations related to guidance on patient treatment methods, taking into account related laws such as the stage of treatment and the Medical Service Act. Additionally, the Constitutional Court recently ruled on the non-benefit cost notification system linked to the explanation of economic costs. However, holding a doctor accountable solely because the doctor's explanation was insufficient has aspects that do not correspond to the actual situation in clinical reality, and may have a reflexive disadvantage that results in a decline in legal rights. Therefore, the doctor's explanation needs to be examined from both perspectives: guaranteeing the patient's right to self-determination and protecting his or her right to decision.
