The aim of this study is to examine the relative economic benefits between the septic tank and exclusive sewage pipe line in designing the large building at combined sewer districts. With the case study of Lotte World Tower Building, we analyze a cost-benefit between two alternatives. The research results showed 2 years of payback period, about ￦6.17 billion of NPV, and 1.93 of B/C ratio for installing the exclusive sewage pipe line in comparison with septic tank. This results provide useful guidelines for policy establishment of the septic tank closure and for plausibility of installing exclusive sewage pipe line when constructing a large building. In the future, it will be necessary to consider additional cost-benefit analysis including burden charge borne by causers, the burden of management responsibility with a exclusive sewage pipe line, and the economic benefits of reducing odor.

In the circumstance of standing out the climate change issue, the purpose of this study is to compare the efficiency of offshore and coastal fisheries according to whether or not greenhouse gas (GHG) emissions are considered, and then to present policy alternatives based on the analysis results. For analysis, the traditional data envelopment analysis (DEA), the slacks-based measure (SBM) and the SBM-undesirable models were used, and robust analysis of variance (ANOVA) and Wilcoxon Signed-rank tests were performed. As a result, the study showed that the average efficiency of fisheries decreased as the traditional DEA extended to the SBM model considering the slack and the SBM-undesirable model including the GHG emissions. Specifically, the average efficiency of the traditional DEA model, SBM model, and SBM-undesirable model was analyzed as 0.7350, 0.5820 and 0.4976 respectively. In addition, the results of the robust ANOVA and Wilcoxon Signed-rank tests all showed that there are statistically significant differences in efficiency between offshore and coastal fisheries as well as among traditional DEA, SBM and SBM-undesirable models. As a policy alternative to the analysis, it was suggested that to improve the efficiency of coastal and offshore fisheries, it is necessary to actively implement the new fishing vessel project and develop smart and electric hybrid fishing vessels.

The purpose of this study is to investigate factors that affect the suicidal ideation of the people with mental disabilities. To this end, the independent variables were analyzed by categorizing them into individual psychological factors, social factors, and demographic characteristics. The analysis data include 969 people with mental disabilities who participated in the 2017 Ministry of Health and Welfare's Research, 'Survey on the Current Status of Mental Disabilities in Community'. The analysis method was frequency analysis, descriptive statistics, and hierarchical multiple regression analysis with SPSS 23.0. As a result of the study, in terms of individual psychological factors, the higher the depression and the lower the mental health confidence, the more suicidal ideation increase. In terms of social factors, the more unregistered disabled groups, the more exposure to violence and discrimination, and the more they live in large cities, the higher their ideation of suicidal. The regression model explained 26.9% of suicidal ideation. The practical and policy implications for the prevention of suicide of the people with mental disabilities based on these results are as follows: First, social factors should be evaluated and considered together, rather than focusing only on individual psychological factors, in seeking policies and intervention programs that reduce suicidal ideation in the people with mental disabilities. Second, in seeking suicide prevention policies for the people with mental disabilities, Protection & Advocacy services should be provided to reduce violence and discrimination experiences. Third, in order to reduce the suicidal ideation of the people with mental disabilities, the mental disability registration system should be reorganized, and policy alternatives should be devised so that those experiencing mental distress can be included into the system.

This paper focuses on the situation in which, as pluralistic democracy spreads globally from the mid-20th century, the concept of publicness, the reason for the existence of traditional public art, is not limited to the physicality of occupying public space or the conditions for creation by public funds, but is seeking a new direction and examine the social significance of these changes. For this purpose, the main body of this paper analyzes the major public art projects of Freee Art Collective who were active in the UK in the early 2000s. Freee performed various public art projects in which individuals constituting a community critically reflect on political, social, and economic issues related to public goods and provide a discourse space for democratic discussion. Their practice suggested a methodology for socially-engaged public art that resists the "Third Way" cultural policy of the New Labour administration. Therefore, this paper argues that Freee's public art seeks alternatives to publicness in that it allows one to resistively think about problematic aspects of hegemonic cultural production of neoliberal cultural policy that pursues political consensus and social harmony. This research about Freee's public art would be significant in that it can serve as an opportunity for critical reflection on the contemplative form and public role of contemporary public art.

Changes have been taking place in North Korea, which has been pushing for selective informatization with a priority on a system safety. North Korea has been developing its own mobile communication industry over the past decade by expanding base stations, producing smartphones on its own, and developing applications useful in real life. Recently, the introduction of 5G technology has been elevated to the status of a national agenda to be fostered as a key industry for national economic development. The time has arrived when the needs of North Korea, which has to advance technology, are aligned with the capabilities of South Korean mobile communication companies, which are seeking to new markets to overcome stagnant growth. The purpose of this paper is to illustrate a cooperative scenario for mobile communications companies between the two Koreas in the early stages of the 4th Industrial Revolution and its core technology 5G, while also making a timely proposal to position North Korea in the GVC. Mobile communications is a large-scale industry that can create synergies from inter-Korean economic cooperation by facilitating exchanges and cooperation between the two Koreas, inducing numerous derivative industries and driving job creation. Joint mobile communications activities with North Korea would be an effective cooperative aspect that can contribute to the economic prosperity of the entire Korean Peninsula.

This study focused on real estate rental income, which is being interested as a means of preparing for old age in the age of low growth and aging. Rental income is seen to function as a safety net of society at a time when it is necessary to live a difficult old age due to the disconnection of income and the extension of the average life span. Therefore, this study conducted the following study on 1,025 households that own rental real estate nationwide. First, the relationship between the characteristics of the household of the rental real estate owner and the real estate rental income was analyzed, and second, it examined whether there is a difference in rental income between the group that engages in income activities other than rental income and the group that only has rental income without income activities. As a result of the analysis, among the demographic and sociological characteristics, gender and spouse were identified as significant variables in rental income. Among the economic characteristics, income and total debt were found to be significant variables. In the case of income activities, rental income was low, and rental income was high when the total debt was high. However, if interest rates rise and the economic recession is prolonged due to unpredictable causes, the owner may suffer from double-use. In preparation for this, it is necessary to review real estate policy alternatives such as easing the period of real estate holdings.

The purpose of this study is to verify the practical validity of financial sanctions, which has recently emerged as the most powerful form of economic sanctions preferred by U.S. foreign policy tool. Based on the theoretical discussion, analyse this study the trend of de-dollarization appearing in connection with financial sanctions and argue that the effectiveness of financial sanctions erode the dollar financial hegemony, which is the source of its power can be degraded, so that its effectiveness could not be so great as most people likely think about. After World War II, there has been an increasing tendency in the international community to favor economic sanctions over the use of military force as an effective means of foreign policy. Among these economic sanctions, a distinct feature that has recently appeared is the remarkable increase in the frequency of use of financial sanctions. The country that favors financial sanctions most is the United States. The reason is that they believe that the power of their own dollar financial hegemony can exert deadly pressure on other countries. Financial sanctions favored by the United States are said to have increased the effectiveness of sanctions by upgrading the pressure of sanctions to the next level. Nevertheless, financial sanctions have a side that underestimates the cost. This problem is found in the signs that the backlash from not only countries subject to financial sanctions but also many countries with interests in these countries is leading to a tendency to de-dollarization. This study will try to see how likely this de-dollarization trend is to offset the effectiveness of financial sanctions.

Carbon neutrality, the international community's practical challenge in response to climate change, is becoming a key industrial strategy for the future development of nations. Despite concerns that China, as an economic powerhouse in the G2, may face challenges leading global climate change efforts due to its high-carbon-emitting industrial structure, it is leveraging carbon neutrality to enhance its industrial competitiveness. The Chinese government has formulated national policies for achieving carbon neutrality and detailed sector-specific plans to implement them. In particular, it aims to leverage carbon neutrality industrial strategies as a lever for adjusting the domestic industrial structure and fostering new industries, at the same time responding to international climate norms and external pressures. However, the effectiveness of carbon-neutral industrial strategies is expected to vary based on regional conditions such as economic and industrial levels. This article analyzes the regional conditions for implementing carbon neutrality in China, as well as the contents and characteristics of major industrial policies. Due to differing levels of economic development and industrial structures, significant variations in carbon emissions, size, emission sources, and efficiency are inevitable across regions. These disparities introduce diverse initial conditions and endogenous factors in pursuing carbon-neutral goals, limiting the direction and implementation of carbon-neutral industrial strategies favoring certain regions. In particular, the extent of policy autonomy granted to local governments regarding carbon neutrality implementation will influence the regional dynamics of central-local environmental governance. Consequently, it is crucial to emphasize regional monitoring alongside comprehensive national research to accurately navigate the path towards carbon neutrality in China. In summary, the article underscores the importance of understanding regional variations in economic development, industrial structure, and policy autonomy for successful carbon neutrality implementation in China. It highlights the need for regional monitoring and comprehensive national research to determine a more precise direction for achieving carbon neutrality.
