Gender is frequently being identified as a key moderator in consumer behavior studies. However, there has been insufficient studies in this field in rural tourism areas. The purpose of this study examined the structural relationships among rural tourism motivation, satisfaction, and loyalty including the moderating effect of gender. Data were collected from 442 farmstay visitors by field survey in rural areas. SPSS 15.0 and LISREL 8.80 statistical package were used to analyze the data. Principle component analysis and path analysis were carried out to identify the structural relationships. Results showed that refreshment and family togetherness of tourism motivation had a negative effect on satisfaction. However, rural life of tourism motivation had a positive effect on satisfaction. Tourists' satisfaction had a positive effect on loyalty. The results also indicated that gender moderated the relationship among tourism motivation, satisfaction, and loyalty. The study suggested that it was important for tourism service marketers to develop proactive relationship marketing techniques that could have a lasting impact on customer retention.

Objectives: People are living longer, but often with diseases or chronic conditions. As a consequence, interest in resolving insurance blind spots is growing. This study provides substandard risk-relevant statistics to help substandard risks who are likely to fall in insurance blind spots obtain insurance coverage, such as the reimbursement of medical costs, as well as to stimulate insurance product development. Methods: This study uses National Health Insurance Service (NHIS) cohort data to determine the relevant statistics. The incidence rates of severe diseases are derived and compared against standard risks to establish a set of relative risk factors. These incidence rates of standard and substandard risks are then compared. Results: Currently, an individual's cancer history is used in the underwriting process for simplified issue insurance. However, underwriting focusing on hospitalization and procedures related to serious illnesses could lower premiums for substandard risks. Moreover, the statistical results could be used to expand the coverage of health insurance products. Conclusions: This study's relative risk factors can be used to derive simplified issue premium rates for substandard risks. They can also be used to implement discount and loading schemes for medical reimbursement insurance and help insurance companies implement proactive risk management.

Should the Korea Maritime Police Agency (KMPA) be a comprehensive, multi-functional organization for a unique on-scene service at sea, as in the case of the U.S. Coast Guard, or should it be simply a water police agency, confining its mission only to law enforcement? The argument about enlarging or limiting KMPA's function has been and will be repeated. In this paper, Lee Sangjib highlights the internal and external issues facing KMPA, stemming partly from deficiencies of its struggles for advancement of the organization and partly from shortcomings of political support for it. In this regard, he urges KMPA to practise a scientific management system for maximizing cost-effectiveness of its administrative resources and for maintaining its identity and characteristics as a lead maritime agency. In addition, he also suggests that KMPA adopt the Total Quality Management System for quality improvements in services and greater efficiency in its organization structure to meet the future competition in the changing political and legal environment. He further recommends the proactive, non-regulatory 'Prevention Through People' program, pioneered by the U.S. Coast Guard, as a way of changing KMPA's existing lopsidedly legalistic culture. He concludes by providing a 6-point vision statement for KMPA from the standpoint of favoring enlarging the function of KMPA.

This paper discussed environmental health policies for the past and coming decade by reviewing the First Comprehensive Environmental Health Plan (2011~2020) and introducing the Second Comprehensive Environmental Health Plan (2021~2030). The major achievement of the First Comprehensive Environmental Health Plan was the establishment of receptor-oriented environmental health policies. However, the main limitations were insufficient policy support for relief and/or recovery from environmental pollution damage and low public awareness of environmental health policies. The Second Comprehensive Environmental Health Plan presents the following major policy tasks: establish an omnidirectional environment health investigation and monitoring system, provide customized environmental health services, improve the environmental health damage relief and recovery system, and promote regional environmental health policies. The Second Plan has a clear distinction from the First Plan in that it expands the field of environmental health from the prevention and management of environmental risk factors to proactive damage response and recovery, which will effectively contribute to alleviating the burden of environmental disease.

Current international negotiation and cooperation for sustainable development are focused on three main themes. The first theme is implementation of Sustainable Development Goals (SDGs). The second theme is development of measures for climate change. The third theme is sustainable management of biodiversity and ecosystem services. In South Korea, responses of government policies and academic studies have been predominantly to one of these three themes. There have not been many integrated efforts to develop countermeasures considering all three international themes. In addition, while "green growth" policies have been setting national agendas for Korea's sustainable development, they must be scrutinized such as why they have not dealt with some parts of these three themes and whether they have ignored one of these themes due to lack of integrated responses. This study finds critical issues in South Korea on how to harmoniously respond to the three themes of international efforts and improve green growth policies. First, to achieve SDGs, the domestic statistical system must be reorganized to track the achievement of "inclusiveness" and "green growth". Second, the climate change response policy should seek inclusion between countries and between social groups. Third, in the field of biodiversity and ecosystem services, it is necessary to establish Korea's identity in global geopolitics and enhance its own traditional ecological knowledge. Fourth, it is necessary to consider how to solve discrepancy between climate change response policies and biodiversity-ecosystem service management policies. Finally, proactive improvement of laws and institutions must occur to promote inclusive green growth.

Purpose: Establishment of a real-time monitoring system for odor control in traditional markets in Gangwon-do and a system for linking prevention facilities. Research design, data and methodology: Build server and system logic based on data through real-time monitoring device (sensor-based). A temporary data generation program for deep learning is developed to develop a model for odor data. Results: A REST API was developed for using the model prediction service, and a test was performed to find an algorithm with high prediction probability and parameter values optimized for learning. In the deep learning algorithm for AI modeling development, Pandas was used for data analysis and processing, and TensorFlow V2 (keras) was used as the deep learning library. The activation function was swish, the performance of the model was optimized for Adam, the performance was measured with MSE, the model method was Functional API, and the model storage format was Sequential API (LSTM)/HDF5. Conclusions: The developed system has the potential to effectively monitor and manage odors in traditional markets. By utilizing real-time data, the system can provide timely alerts and facilitate preventive measures to control and mitigate odors. The AI modeling component enhances the system's predictive capabilities, allowing for proactive odor management.

Korean aviation authority required air service providers to submit public disclosure of aviation safety investment to encourage proactive and voluntary safety investments. In 2023, two airport operators and seventeen airlines disclosed their safety investment results and plans for the first time. This study aims to examine and analyze the current status of the disclosure system, identify insights for its development, and set directions for the future. Safety investments by airport operators decreased by 14.3% in 2022 compared to 2021 due to decreased aviation demand. Airline increased their safety investment by 46% to 4 trillion won, investing heavily in MRO and aircraft replacement, leading to a decrease in the average fleet age by 0.8 years. FSCs have shown a significantly higher level of safety investment compared to LCCs. However, LCCs show higher safety investment relative to revenue. It is necessary to consider the characteristics of each operator as well as the scale when comparing safety investments. A roadmap is suggested based on the importance of disclosure items for the strategic approach and improvement measures for the aviation safety investment disclosure system.

The Low Earth Orbit satellite network has the unique characteristics of the non-uniform and time-variant traffic load distribution, which often causes severe link congestion and thus results in poor performance for delay-sensitive flows, especially when the network is heavily loaded. To solve this problem, a novel adaptive routing algorithm, referred to as the delay-oriented adaptive routing algorithm (DOAR), is proposed. Different from current reactive schemes, DOAR employs Destination-Sequenced Distance-Vector (DSDV) routing algorithm, which is a proactive scheme. DSDV is extended to a multipath QoS version to generate alternative routes in active with real-time delay metric, which leads to two significant advantages. First, the flows can be timely and accurately detected for route adjustment. Second, it enables fast, flexible, and optimized QoS matching between the alternative routes and adjustment requiring flows and meanwhile avoids delay growth caused by increased hop number and diffused congestion range. In addition, a retrospective route adjustment requesting scheme is designed in DOAR to enlarge the alternative routes set in the severe congestion state in a large area. Simulation result suggests that DOAR performs better than typical adaptive routing algorithms in terms of the throughput and the delay in a variety of traffic intensity.

Developing a personalized system on a user's behalf which is working around the Internet-based marketplace is one of the challenging issues in intelligent e-business, especially mobile commenrce. It has been highly recommended that such a mobile personalized system has to perceive the user's needs a priori by tracking user's current context such as location with activity and then to identify the current needs dynamically and proactively. Automatically and unobtrusively getting user's context is an inevitable feature for the development of autonomous mobile commenrce. However, personalization methodologies and their feasible architectures for context-aware mobile commerce have been so far very rare. Hence, this paper aims to propose a context-aware mobile commerce development methodology by applying agent and semantic web technologies for personalized reminder system, which is one of the mobile commerce support system. We revisited associationism to understand a buyer's need identification process and adopt the process as 'purchase based on association' to implement a personalized reminder system. Based on this approach, we have showed how the agent-based semantic web service system can be used to realize need-aware reminder system. NAMA(Need-Aware Multi-Agent), a prototype system, has been implemented to show the feasibility of the methodology and framework under mobile setting proposed in this paper. NAMA embeds bluetooth-based location tracking module and identify what a user is currently looking at through her/his mobile device such as PDA. Based on these capabilities, NAMA considers the context, user profile with preferences, and information about currently available services, to aware user's current needs and then link her/him to a set of services, which are implemented as web services.
