Electric power utilities are facing increasing uncertainties regarding the economic, political, societal, environmental constraints under they operate and plan their future systems. The utilities have to integrate consumers' interruption cost representing reliability worth of electricity into the process of determining the optimum investment level. In order to do so, the estimated outage cost must be included into quantitative index corresponding to system capital and operation investment cost to establish an optimal expansion plan. This paper is a study on the outage cost assessment by using macro approach for calculating IEAR(Interrupted Energy Assessment Rates) and the TRELSS(Transmission Reliability Evaluation for Large-Scale Systems) program was used to calculate EENS(Expected Energy Not Served).

최근 공유가치창출(CSV: Creating Shared Value)이 초미의 관심을 끌고 있다. 이는 기존의 기업의 사회적 책임(CSR: Corporate Social Responsibility) 성과에 사회적 경제적 가치창출이라는 사회적 문제해결의 대안이 될 수 있다는 시각이 작용하기 때문이다. CSR과 CSV의 성과를 구분하여 확인하기는 어려움이 있다. 따라서 CSV 성과에 대한 실증분석 기법의 개발과 소비자의 CSV에 대한 인식 및 태도가 검증될 수 있는 방법론의 개발이 필요하다. 기업은 가치사슬의 혁신을 통한 사회문제의 해결과 더불어 경쟁우위를 점할 수 있어야 한다. 진일보한 CSV 논의가 필요한 시점으로 파악하는 까닭은 아직 CSV가 초기 연구 단계에 머물러 있는 실정이기 때문이다. 이에 본 연구는 우선적으로 CSV 의의와 필요한 배경, 기업의 사회적 책임(CSR)과 공유가치창출(CSV)의 상호비교 분석을 하였다. 더 나아가 CSV의 기존 연구의 범위가 매우 협소했던 한계점을 넘어 가치사슬에서 CSV의 필요성을 피력하고자 한다. 오늘날 다수의 기업들은 기업의 사회적 책임을 수행하기 위한 노력을 기울여 왔다. 그러나 기업의 지속성장성 측면에서 단순히 CSR의 충족만으로는 수익창출을 위한 비즈니스모델로써는 한계가 있음이 지적되었다. 하나의 대안으로 최근 공유가치창출 도입의 필요성이 제기되고 있는 것이다. 선행연구를 통해 가치사슬관점의 CSV를 경제적 사회적 문화적 가치가 기업이미지 및 기업신뢰도를 매개로 구매의도로 이어지는 인과관계를 실증분석을 통해 밝혀 보았으며 구체적인 연구 결과는 다음과 같다. 첫째, 사회적 가치와 문화적 가치는 기업이미지에 긍정적 영향을 미치는 것으로 나타났다. 이는 CSV 활동을 통하여 소비자들이 해당 기업에 좋은 인상을 가질 수 있도록 하는 단초가 됨을 시사한다. 둘째, 사회적가치는 기업신뢰도에 긍정적 영향을 미치는 것으로 파악되었다. 따라서 CSV가 기업의 비용으로만 인식되는 것이 아닌 미래의 발전과 더불어 상생의 대안이 될 수 있다는 관점으로 접근해 나가야 할 것이다. 셋째, 기업이미지와 기업신뢰도 모두 구매의도에 영향을 미치는 것으로 나타났다. CSV 활동을 통해 기업에 대한 호의적인 평가를 유도할 수 있다는 관점에서 기업의 최종 목표인 지속적 이익창출과 연계된다는 것을 감안하여 중장기적 전략으로 접근할 필요성이 있다고 판단된다.

본 연구의 목적은 한국의 학교교육이 학생들의 공동체의식을 함양하는데 기여하고 있는지 여러 문헌과 자료들에 근거해서 알아보는 것이다. 공동체의식과 밀접하게 관련 있는 주제로, 학교에서 이루어지고 있는 도덕교육, 학생들의 자원봉사활동 및 한국사회에 대한 인식을 살펴보았다. 그 결과, 우리의 학교교육은 공동체의식을 함양하는데 그 목적을 두기 보다는 개인의 목표를 달성하기 위한 도구적 기능에 국한되어 있었다. 도덕교육은 형식적인 수준에 머물러 있었으며, 자원봉사활동도 점수를 따기 위한 의무적인 활동의 성격이 강했다. 학생들의 학교와 한국국민 및 한국사회에 대한 인식도 상당히 부정적이었다. 결론에서, 이러한 현실에 대한 비판적 시각에서 공동체의식을 함양할 수 있는 방안을 논의하였다.

Purpose: This study conducted an economic evaluation of hospital-based home care services for the patients who had undergone breast cancer surgery. Methods: A total of 12,483 patients over 18 years of age who had received breast cancer surgery in 26 tertiary hospitals in 2018 were analyzed with the claim data from the Health Insurance Review & Assessment Service using cost-minimization analysis and societal perspectives. Results: There were 156 patients who utilized hospital-based home care services within 30 days after breast cancer surgery, and they received 2.17 (SD=1.17) hospital-based home care service on average. The average total cost was 5,250,028 KRW (SD=1,905,428) for the group receiving continuous hospital-based home care and 6,113,402 KRW (SD=2,033,739) for the group not receiving continuous hospital-based home care (p<.001). The results of the economic evaluation of continuous hospital-based home care services in patients who had undergone breast cancer surgery indicated a total benefit of 953,691,000 KRW, a total cost of 819,004,000 KRW, and a benefit-cost ratio of 1.16 in 2018. Conclusion: Continuous hospital-based home care was considered economically feasible as the total costs for the group receiving continuous hospital-based home care were lower than those of the group not receiving continuous hospital-based home care. Therefore, policy modification and financial incentives are recommended to increase the utilization of hospital-based home care services for patients who had undergone breast cancer surgery.

Purpose: The purpose of this study was to compare the costs and benefits of home nursing care services between public health centers (PHC) and private hospitals. Method: Participants were 105 patients who had received home nursing care services from a private hospital or public health center. From a societal perspective, the researcher identified the costs and benefits of the services using performance data and calculated the net benefit and benefit/cost ratio. Result: The net benefit of the home nursing care service based in the PHC was 165.9 million won and benefit/cost ratio was 2.0, while the net benefit of the home nursing care services by the private hospital was 141.1 million won and benefit/cost ratio was 1.7. Both types of programs were economically validated. Conclusion: Home nursing care services were basically efficient as the results showed a positive net benefit. A cost-benefit analysis indicated that the PHC-based home nursing care services were more efficient than that of the private hospital. With limited human resources and management standards in public health centers, results suggest the need for a more systematic management of the home nursing care service to improve the health of this vulnerable community population.

As conversational AI systems such as ChatGPT have become more advanced, researchers are exploring ways to use them in education. However, we need effective ways to evaluate these systems before allowing them to help teach students. This study proposes a detailed framework for testing conversational AI across three important criteria as follow. First, specialized benchmarks that measure skills include giving clear explanations, adapting to context during long dialogues, and maintaining a consistent teaching personality. Second, adaptive standards check whether the systems meet the ethical requirements of privacy, fairness, and transparency. These standards are regularly updated to match societal expectations. Lastly, evaluations were conducted from three perspectives: technical accuracy on test datasets, performance during simulations with groups of virtual students, and feedback from real students and teachers using the system. This framework provides a robust methodology for identifying strengths and weaknesses of conversational AI before its deployment in schools. It emphasizes assessments tailored to the critical qualities of dialogic intelligence, user-centric metrics capturing real-world impact, and ethical alignment through participatory design. Responsible innovation by AI assistants requires evidence that they can enhance accessible, engaging, and personalized education without disrupting teaching effectiveness or student agency.

In recent times, many accidents have occurred due to challenges in accurately identifying the location of workers, posing a significant societal concern demanding resolution. Therefore, it is essential to develop smart luminescent safety attire to enhance worker visibility in dim environments, thereby curbing accidents. In this study, we propose the utilization of textile-based OLED devices in creating smart luminescent safety clothing, aiming to augment the discernibility of workers over extended distances in low-luminance environments. In view of this, we engineered an attachable textile-based OLED module that balances high luminous efficiency with wearer comfort. Subsequently, a prototype smart luminescent safety clothing was demonstrated, and a performance evaluation was conducted to determine whether any discomfort occurred on wearing it. The fabricated OLED luminous module exhibited high luminance, thus validating the feasibility of creating smart luminescent attire with adequate brightness. Furthermore, there was no significant wearing stress observed, even after wearing it for more than 8 hours, and there was no impediment to various work-related movements. Through this research, we successfully demonstrated OLED based on smart luminescent safety clothing, which has the potential for wide-ranging applications across various industries and occupations, and is expected to play a crucial role in averting safety incidents.

Objectives: Overactive bladder(OAB), defined as 'urgency, with or without urge incontinence, usually with frequency and nocturia', is a major burden for patients and impairs quality of life. The aim of this study is to evaluate the cost-effectiveness of antimuscarinic agents for the treatment of overactive bladder including quality of life in societal perspective. Methods: A decision-analysis model was developed to compare the cost-effectiveness of solifenacin and tolterodine IR over 12 weeks. We used data from the published literature to develop the framework for the model. Resource utilization and costs were calculated with public institutional data and supplemented this information with clinical expert opinion, where necessary. Results: The expected costs per patient for solifenacin were 48,762 KRW less expensive than tolterodine IR over 12 weeks. Also, all outcomes including quality of life for solifenacin were more effective than tolterodine IR over 12 weeks. In conclusion, solifenacin dominates tolterodine IR and appears to be cost-effective options for the management of overactive bladder.

This study was conducted to analyze the cost-utility of ramosetron monotherapy, trimebutine monotherapy and trimebutine+loperamide combination therapy in male diarrhea-predominant patients with irritable bowel syndrome (IBS) in Korean healthcare setting. We constructed a decision-analytical model to estimate both total costs for each state of health and outcomes such as IBS-symptoms improvement for 3 and 6 months time horizon. Base analysis found that for ramosetron treatment with the price of KW910 for 5 ${\mu}g$ tablet, incremental cost effectiveness ratios (ICERs, cost per quality-adjusted life day) were KW85,000 and KW62,000 for 3 months and 6 months, respectively, compared with trimebutine. But ramosetron was a dominant strategy when compared with trimebutine+loperamide for both 3 months and 6 months. Sensitivity analyses showed robust results for drug acquisition costs till ramosetron price of KW950/tablet. In conclusion, ramosetron was a cost-effective regimen compared with trimebutine or trimebutine+loperamide from the societal perspective.

The overall goal of a safety based railroad system is either to eliminate hazards in designing or to minimize the possibility of it. In order to indicate system safety or low risk although it may not be possible to achieve zero risk conditions, first, it shall ensure that any disasters would occur due to system operation because the prescribed specifications are properly fulfilled and there are no failures of any kind. Second, the risk of faults or failures leading to a mishap must be eliminated or minimized by using fault-tolerance or fail-safe procedures. This paper will attempt to summarize the personal and social risk criterion at widely scattered points, presently used as a safety approach in all over EU, in order to establish the step by step procedures of the detailed standard for railway facilities. In addition, we present the new safety analysis method using the SIL-based evaluation standard and the Reachability Graph of the Petri Net.
