This study investigated whether an educational program could alter students' perceptions of the causes of and solutions to climate change. On October 23, 2020, a 3-hour climate change educational program was provided to 400 high school students in Suncheon City, (Jeonnam Province, South Korea). According to the program, climate change represents a social dilemma, or tragedy of the commons; it also asserts that collective action aimed at strengthening government policy is the optimal solution to climate change, and concludes that motivated citizens should convey their opinions directly to the government through political action. After the program, the students made and shared placards calling for policy-based responses to climate change. Questionnaires completed by the students before and after the program revealed that their perceptions of the causes of and solutions to climate change changed significantly. This case study indicates that education programs have the potential to alter students' perspectives and promote actions aimed at mitigating and adapting to climate change.

The objective of this paper is to formulate strategies and action programs for developing sustainable agriculture in Korea. There is increasing evidence that agriculture has been preoccupied with increasing productivity much to the detriment of environmental degradation. The issue of increasing agricultural productivity so as not to undermine the environment is a difficult task. In reality, there are many definitions of sustainable agriculture and sustainable agricultural development. In this paper, sustainable agriculture is defined by its ability to ensure future supplies of agricultural products at acceptable economic and environmental costs to the society. Sustainable agriculture development refers to the optimal level of interaction among the three dimensions - the environmental, the economic and the social - through dynamic and adaptive processes of trade-off. In order to formulate the strategies for developing sustainable agriculture, three stage approaches such as strategic analysis, strategic choice, and strategic implementation are employed. The basic framework for strategies of sustainable agriculture development consists of five steps such as vision, targets, principles, action plan and policy instruments. The major action plans for activating formulated strategies are suggested as integrating agricultural and environmental policy measures, establishing the system of optimal agri-environmental resources management practices, establishing safe and high quality product system and its effective marketing system, increasing the R&D investment for developing sustainable agro-technology, developing indicators for measuring sustainable agricultural development, and taking a share in related roles for all parties including farmers, consumers, policy makers, researchers and NGOs.

The stability, reliability and efficiency of a smart ship are important issues as the interest in an autonomous ship has recently been high. An automatic collision avoidance system is an essential function of an autonomous ship. This system detects the possibility of collision and automatically takes avoidance actions in consideration of economy and safety. In order to construct an automatic collision avoidance system using reinforcement learning, in this work, the sequential decision problem of ship collision is mathematically formulated through a Markov Decision Process (MDP). A reinforcement learning environment is constructed based on the ship maneuvering equations, and then the three key components (state, action, and reward) of MDP are defined. The state uses parameters of the relationship between own-ship and target-ship, the action is the vertical distance away from the target course, and the reward is defined as a function considering safety and economics. In order to solve the sequential decision problem, the Deep Deterministic Policy Gradient (DDPG) algorithm which can express continuous action space and search an optimal action policy is utilized. The collision avoidance system is then tested assuming the $90^{\circ}$intersection encounter situation and yields a satisfactory result.

한 때 세계 7위의 규모를 자랑하던 한진해운 파산 원인을 두고 대부분의 학자와 언론은 경영의 실패나 CEO 리스크로 바라보았다. 그러나 이 연구에서는 한진해운을 파산하게 한 원인을 행동경제학 관점에서 선박 투자의 군중집단행동에 있다고 바라보았고, 이 군중집단행동이 생기게 된 배경으로 우리 정부의 유연하지 못한 선대 확충 정책이 있었음을 지적하였다. 요컨대 한진해운 파산 원인은 호황기 선박 매입에 있었고 호항기 선박 매입의 근본 원인으로 '타인을 행동을 쫓아서 행동해야만 안심을 하는 군중집단행동'을 지적하였다. 또한, 우리 정부가 설정한 '해운경쟁력 = 선대 규모'라는 목표를 달성하기 위해 불황기와 심지어 호황기에도 선박 매입을 유도하는 정책을 펼쳤고, 이 정책이 시장으로 하여금 '지금 선박을 사도 좋은 시기'라는 신호를 주었음을 지적할 수 있다.

Purpose: This paper proposes the non-periodic preventive maintenance policy based on the level of cumulative hazard intensity. We aim to construct a cost-effectiveness on the proposed model with relaxing the constraint on reliability. Methods: We use the level of cumulative hazard intensity as a condition variable, instead of reliability. Such a level of cumulative hazard intensity can derive the reliability which decreases as the frequency of preventive maintenance action increases. We also model the imperfect preventive maintenance action using the proportional age setback model. Conclusion: We provide a numerical example to illustrate the proposed model. We also analyze how the parameters of our model affect the optimal preventive maintenance policy. The results show that as long as high reliability is guaranteed, the inefficient preventive maintenance action is performed reducing the system operation time. Moreover, the optimal value of the proposed model is sensitive to changes in preventive maintenance cost and replacement cost.

This study attempted to develop integrated family policy. For this purpose, a delphi survey was conducted twice among 15 professionals regarding the general contents of family policy, the goals and outcomes of president Roh's administration, the direction and plan of action for future family policy. The results of this study are as follows: Firstly, the main results of president Roh's administration were the creation of the Ministry of Women and Families, and the Healthy Families Law. Nevertheless, that government had no long-term vision or action programs. Secondly, there are two aspects of family policy which one is family members based and the other is family life cycle based. Accordingly the subjects of this study insist that family policy has to cover people's whole life, all families regardless of family structure, and has to integrate the plans and programs which have been served to individuals, for example, women, child, youth, and elderly. Thirdly, the orientations of future family policy are to be toward happiness, health, equality, coexistence, harmony, growth, generosity, diversity, self-control, and a sustainable society. So the concept of the integrated family policy has to cover all aspects of the family and the diversity of family life. Therefore, the service delivery system for family policy has to converge into the Healthy Family Center.

Although the New National Health Promotion Plan 2010 target to reduce health inequalities, whether the program will be effective for reducing the health inequalities in Korea remains quite unclear. More and more developed countries have been started to concentrate on comprehensive policies for reducing health inequalities. The health policies of the UK, Netherlands, and Sweden are the most wellknown. I propose that a comprehensive blueprint for tackling health inequalities in Korea should be made and that it must contain five domains: a target, structure and process, life-course approach, area-based approach, and reorganization of health care resources. The target should be based on determinants of health and more attention should be paid to socioeconmic factors. The structure and process require changes from the national health care policy based on medical services to the national health policy that involves the establishment of a Social Deputy?Prime Minister and the strengthening multidisciplinary action. A life-course approach especially focused on the early childhood years. Area-based approach such as the establishment of healthy communities, healthy schools, or healthy work-places which are focused on deprived areas or places is also required. Finally, health care resources should be a greater investment on public resources and strengthening primary care to reduce health inequalities. The policy or intervention studies for tackling health inequalities should be implemented much more in Korea. In addition, it is essential to have political will to encoruage policy action.
