Despite the importance of customer satisfaction corresponding to the phenomenal development of the gas industries, supplier-centered management still prevails in the city gas industry due to the monopolistic market environment. However, customer's demands for diverse and higher services are ever growing in the midst of the development and the accelerated competition of the service industries. In this context, customer satisfaction management may be the best style of management for establishing a short, mid and long-term foundation of growth. This paper derives directions for improving customer satisfaction management in such 3 areas as systematic, technological and service improvement from the environmental changes as well as from the customer needs. Based on the survey and comparative analysis of customer satisfaction, we also suggest 5 growth strategies to maintain sustainable development of the gas industry in the midst of competitive environment between city gas companies and among diversified energy businesses and to protect rights of the city gas consumers.

Background: A job-specific Worker's Health Surveillance (WHS) for hospital physicians is a preventive occupational health strategy aiming at early detection of their diminished work-related health in order to improve or maintain physician's health and quality of care. This study addresses what steps should be taken to determine the content of a job-specific WHS for hospital physicians and outlines that content. Methods: Based on four questions, decision trees were developed for physical and psychological job demands and for biological, chemical, and physical exposures to decide whether or not to include work-related health effects related to occupational exposures or aspects of health reflecting insufficient job requirements. Information was gathered locally through self-reporting and systematic observations at the workplace and from evidence in international publications. Results: Information from the decision trees on the prevalence and impact of the health- or work-functioning effect led to inclusion of occupational exposures (e.g., biological agents, emotionally demanding situations), job requirements (e.g., sufficient vision, judging ability), or health effects (e.g., depressive symptoms, neck complaints). Additionally, following the Dutch guideline for occupational physicians and based on specific job demands, screening for cardiovascular diseases, work ability, drug use, and alcohol consumption was included. Targeted interventions were selected when a health or work functioning problem existed and were chosen based on evidence for effectiveness. Conclusion: The process of developing a job-specific WHS for hospital physicians was described and the content presented, which might serve as an example for other jobs. Before implementation, it must first be tested for feasibility and acceptability.

Most automated vehicle evaluation scenarios are developed based on the typical driving situations that automated vehicles will face. However, various situations occur during actual driving, and sometimes complex judgments are required. This study is to define a situation that requires complex judgment for safer driving of an automated vehicle as a dilemma situation, and to suggest a driving strategy necessary to secure driving safety in each situation. To this end, we defined dilemma situations based on the automated vehicle ethics guidelines, the criteria for recognition of error rate in automobile accidents, and suggestions from the automated vehicle developers. In addition, in the defined dilemma situations, the factors affecting movement for establishing driving strategies were explored, and the priorities of factors affecting driving according to the Road Traffic Act and driving strategies were derived accordingly.

Norovirus (NoV) prevalence was investigated in 100 sewage samples collected from 35 individual septic tanks around the drainage basin of Jaran Bay, Korea in January, May, and July of 2017. Genotypes and diversity of NoV strains detected in sewage samples were also assessed using the conventional RT-PCR and phylogenetic analysis. NoV GI or GII were detected in 22 (22.0%) and 24 (24.0%) samples, respectively. Thirteen genotypes were identified with three dominant genotypes (GI.9, GII.5 and GII.17) and GII.17 showed relatively higher prevalence during the survey period. GII.17 strains were clustered into recombinant type variant or NoV GII.17 Kawasaki variant. NoV GII.17 strains were considered emergent epidemic variants with widespread circulation. NoV surveillance strategy should include both environmental (sewage) and clinical data to reveal minor NoV genotypes likely cause of asymptomatic or underreported infections in the local population.

This report presents guidelines for the systematic management of packaging, storage, transportation, and traceability of source cells used for organoid research. Given the important role of source cells in organoid studies, it is important to ensure the preservation of their quality and integrity throughout transportation and distribution processes. The proposed guidelines, therefore, call for a cohesive strategy through these stages to minimize the risks of contamination, deterioration, and loss-threats that significantly compromise the safety, efficacy, and efficiency of source cells. Central to these guidelines is the quality control measures that include roles and responsibilities across the entire supply chain, with recommendations specific to packaging materials, transportation facilities, and storage management. Furthermore, the need for an integrated management system is emphasized, spanning from source cell collection to the final application. This system is crucial for maintaining the traceability and accountability of source cells, facilitating the sharing, distribution, and utilization on a global scale, and supporting to advance organoid research and development.

The study aimed to investigate the influence of perceived patient safety culture on patient safety management activity in the dental hygienists. Methods: A self-reported questionnaire was completed by 292 dental hygienists in Seoul, Incheon and Gyeonggido from March 1 to April 8, 2016. The questionnaire consisted of general characteristics of the subjects (9 items), patient safety culture (44 items), and patient safety management activity (25 items) by Likert 5 point scale. Data were analyzed by t test, one way ANOVA, stepwise multiple regression test, and post-hoc Tukey test using SPSS 18.0 program. Results: The perceived patient safety culture was 3.50 on average. Entire organization was the highest score (3.68) and followed the communication process (3.55), the environment of work unit (3.47), the attitude of supervisor/manager (3.45), and the frequency of events reported (2.98). The average of patient safety management activity was 3.71. As for the factors of patient safety culture on patient safety management activity, communication process was the most influential factor (${\beta}=0.268$), and followed the entire organization (${\beta}=0.265$), the environment of work unit (${\beta} =0.166$), the frequency of events reported (${\beta}=0.104$), and among the control variables. Work place proved to be the only significant variable. Conclusions: In order to promote patient safety management activity of dental institutions, the patient safety culture should be created and established. The influence of communication process and patient safety culture at entire organization level was huge. So the environment of work unit and the perceived patient safety culture in the process of reported events were influencing factors. The strategy for patient safety management activity should be considered because of low level of perceived patient safety culture.

In this study, a systematic survey was employed to investigate managers' awareness on the safety culture project in small- to medium-sized industries. The existing regulatory and technology-oriented disaster prevention strategy has been implemented to reduce industrial accidents within a short timeframe, but it is essential to reduce fundamental accidents as well by improving the organizational safety culture or software elements, such as safety awareness. Questionnaires and interviews were conducted to examine the managers' awareness about safety culture, consisting of 17 questions related to safety consulting and with the participation of 191 executives and safety managers. The results showed a significant difference in the self-pay rate of safety consulting depending on the size of the workplace under evaluation. Based on the results, the safety-consulting business focused on providing differentiated consulting support and realistic improvement plans according to the workplace size. The study concluded that it is possible to reduce fundamental human errors and improve organizations' safety awareness or safety culture by employing safety consulting differentiated by workplace size.

This study was undertaken to strategize the mixed traffic operation of autonomous vehicles in the pilot zone. This was achieved by analyzing the changes expected when autonomous vehicles are mixed in the autonomous vehicle pilot zone. Although finding a safe and efficient traffic operation strategy is required for the pilot zone to serve as a test bed for autonomous vehicles, there is no available operation strategy based on the mixture of autonomous vehicles. In order to presents a traffic operation strategies for each period of autonomous vehicle introduction, traffic efficiency and safety analysis was performed according to the autonomous vehicle market percentage rate. Based on the analysis results, the introduction stage was divided into introductory stage, transition period, and stable period based on the autonomous vehicle market share of 30% and 70%. This study presents the following traffic operation strategies. Considering the traffic flow operation strategy, we suggest the advancement of the existing road infrastructure at the introductory stage, and operating an autonomous driving lane and the mileage system during the transition period. We also propose expanding the operation of autonomous driving lanes and easing the speed limit during the stable period. In the traffic safety strategy, we present a manual and legal system for responding to autonomous vehicle accidents in the introductory stage, an analysis of the causes of autonomous vehicle accidents and the implementation of preventive policies in the transition period, and the advancement of the autonomous system and the reinforcement of the security system during the stable period. Through the traffic operation strategy presented in this study, we foresee the possibility of preemptively responding to the changes of traffic flow and traffic safety expected due to the mixture of autonomous vehicles in the autonomous vehicle pilot zone in the future.

최근 남중국해(South China Sea: 南中國海)가 동아시아 해양안보의 중심 이슈로 대두되고 있다. 아울러 남중국해 문제가 당사국 간 해양분쟁 및 해양경계획정 이슈만이 아닌, 제3자 개입 등의 다자간 해양분쟁과 대립으로 확산되는 매우 복잡한 양상을 보이고 있다. 이러한 남중국해 해양문제는 미국과 중국 간의 강대국 경쟁구도가 적용되어 힘의 시현을 위한 대결 국면이 되는 반면, 중국이 전통적 해양이익을 구단선(nine dash line)을 근거로 주장하면서 국제법 적용 문제에 따른 법적 문제의 성격을 나타내고 있다. 이에 따라 최근 남중국해 상황은 '항해의 자유(Freedom of Navigation)' 보장을 주장하는 미국, 역사적 권리 보장을 위해 일반적 조치를 강행하고 해군력을 증강시키는 중국, 그리고 남중국해를 경유하는 수많은 선박들의 항해 안전(navigational safety)을 강조하는 역내 국가 간 의견이 표출되는 복잡한 양상으로 나타나고 있다. 특히 최근 중국이 상설중재재판소의 남중국해 중재판결을 무시하여 국제법 적용이 어려운 가운데 포괄적 동아시아 해양안보 차원에서 남중국해 이슈 해결을 위한 새로운 접근방안이 요구되고 있다. 이는 남중국해에 대한 당사국 간 평화적 분쟁 해결과 더불어, 강대국 간의 전략적 함의에 의한 해결이 병행되어야 함을 의미한다.
