This study is intended to figure out determinants affecting the economic preparations for old age of pastors from major four protestant associations having a church ministerial pension system: the General Assembly of Presbyterian Church in Korea (GAPCK), the Presbyterian Church of Korea (PCK), the Presbyterian Church in the Republic of Korea (PROK), and the Korean Methodist Church (KMC). Thereby, it conducted a survey to 452 pastors from the four religious associations in Korea. The followings sum up the results of this research. First, it was shown that the conventional idea that there is no need for pastors to prepare for their old age or their preparations for old age imply disbelief had been diminished. Second, there were few pastors who had made economic preparations for their old age privately. Third, associations adopting a compulsory church ministerial pension system were PCK, PROK, and KMC indicating a high occupation of more than 75% whereas GAPCK with an optional system showed a very low percentage of 11.5%. Fourth, with regard to the national pension system, the associations except for PROK (61.8%) had more non-enrolled pastors (53.3%), and they responded economic difficulty as the biggest reason for the unenrollment. Fourth, determinants affecting their economic preparations for old age were academic career, total income, church independency, church reserving, and national pension enrollment. Fifth, among the pastors from the four associations, the ones of PROK prepared for their old age best in consideration of GAPCK. According to the results of this paper, the most critical determinant affecting pastors' economic preparations for old age was total income. Pastors with higher income can make church ministerial pension, national pension, and private preparations while the ones with lower income cannot afford for public as well as private preparations; that is, there exists a polarization phenomenon in pastors' economic preparations for old age. Therefore, it is necessary to make devices to narrow the income gap between pastors in religious associations. Second, even in the associations having a compulsory church ministerial pension system, many pastors were not insured, so it is needed to reform or improve the pension system. Third, it is also required to better the national pension system and change the recognition on it.

This study is aiming at identifying the foreward and backward lingkage effects of the farm land base development project. Korean Government has continuously carried out farmland base development projets including the integrated agricultural development projects. large and medium scale irrigation projects and the comprehensive development of the four big river basin including tidal land reclamation and estuary dam construction for the all weather farming since 1962. the starting year of the five year economic development plans. Consequently the irrigation rate of paddy fields in Korea reached to 75% in 1998 and to escalate the irrigation rate, the Government had procured heavy investment fund from IBRD. IMF and OECF etc. To cope with the agricultural problems like trade liberalization in accordance with WTO policy, the government has tried to solve such problems as new farmland base development policy, preservation of the farmland and expansion of farmland to meet self-sufficiency of foods in the future. Especially, farmland base development projects have been challanged to environmental and ecological problems in evaluating economic benefits and costs where the value of non-market goods have not been included in those. Up to data, in evaluating benefits and costs of the projects, farmland base development projects have been confined to direct incremental value of farm products and it's related costs. Therefore the projects'efficiency as a decision making criteria has shown the low level of economic efficiencies. In estimating economic efficiencies including Leontiefs input-output analysis of the projects could not be founded in Korea at present. Accordingly this study is aimed at achieving and identifying the following objectives. (1) To identify the problems related to the financial supports of the Government in implementing the proposed projects. (2) To estimated backward and foreward linkage effects of the proposed project from the view point of national economy as a whole. To achieve the objectives, Hwangrak benefited area with reservoir which is located in Seosan-haemi Disticts, Chungnam Province were selected as a case study. The main results of the study are summarized as follows : a. The present value of investment and O & M cost were amounted to 3,510million won and the present value of the value added in related industries was estimated at 5.913million won for the period of economic life of 70 years. b. The total discounted value of farm products in the concerned industries derived by the project was estimated at 10,495million won and the foreward and backward linkage effects of the project were amounted to 6,760 and 5,126million won respectively. c. The total number of employment opportunities derived from the related industries for the period of project life were 3,136 man/year. d. Farmland base development projects were showed that the backward linkage effects estimated by index of the sensitivity dispersion were larger than the forward linkage effect estimated by index of the power of dispersion. On the other hand, the forward linkage effect of rice production value during project life was larger than the backward linkage effect e. The rate of creation of new job opportunity by means of implementing civil engineering works were shown high in itself rather than any other fields. and the linkage effects of production of the project investment were mainly derived from the metal and non-metal fields. f. According to the industrial linkage effect analysis, farmland base development projects were identified economically feasible from the view point of national economy as a whole even though the economic efficiencies of the project was outstandingly decreased owing to delaying construction period and increasing project costs.

Mokpo port marked the $131^{st}$ anniversary of its opening in 2018. while the Mokpo has taken the new port development initiatives, it is limited by inefficient port functioning due to the lack of maritime port policy and government investment. Hence, port logistics has not been activated. Additionally, studies on Mokpo port have not been conducted, and knowledge available on the port is declarative in nature. On the other hand, research on port competitiveness focuses on how to analyze the factors that determine port competitiveness. Therefore, this study was intended to expand the existing research on Mokpo port and conduct an analysis of non-competitiveness factors and suggested improvements by considering the operational aspect of Mokpo port. In this regard the importance of non-competitiveness factors was assessed through an analytic hierarchy process(AHP) analysis and the influence of the non-competitiveness factors was analyzed through an fuzzy structural modeling(FSM) analysis. The result of the AHP analysis show ed the important non-competitiveness factors included the deactivation of industrial complexes around Mokpo port, the number of liner route, the cost of the pilot and tug. Accor ding to the FSM analysis, the top level included the non-competitive factors at Mokpo port; the intermediate level included the number of liner routes, cost of pilot and tug, enrance and clearance fee, costs of inland transportation, fee for port facilities, and loading and unloading costs; and the bottom level comprised the most non-competitive factors including the deactivation of industrial complexes around Mokpo port, hinterland connectivity, access to international port, incentives, and cost of transportation and storage. Based on the results of analysis, improvements were suggested for non-competitive factors of Mokpo.

With the advancement of Fourth Industrial Revolution technologies, the maritime sector is actively developing technologies and policies related to autonomous ships. This study aims to identify and prioritize various factors influencing the adoption of Maritime Autonomous Surface Ships (MASS) by conducting surveys among experts and professionals in the maritime industry. To achieve this, relevant factors related to the adoption of autonomous ships were examined through a review of previous research, and survey questions for pairwise comparison using the Analytic Hierarchy Process (AHP) were developed based on the insights of industry experts. The pairwise comparison items were categorized into four main factors at the highest level, with each factor further subdivided into sub-factors to establish their priorities. The survey results, which distinguish between shipowner and non-shipowner groups, reveal that, among the main factors-economic, legal and policy, safety and security, and technical-the shipowner group prioritized economic factors, though the difference from safety and security factors was relatively minor. In contrast, the non-shipowner group rated safety and security factors as the highest priority, with economic factors ranked lowest. Further analysis of the sub-factors across both groups indicated that, for economic factors, the increase in operational profit was most critical; for legal and policy factors, regulations related to structural equipment were paramount; for safety and security factors, the risk of equipment and machinery failure was key; and for technical factors, accident response technology was most significant. This study provides strategic insights for stakeholders by systematically analyzing decision factors for adopting MASS through AHP analysis. The findings enable companies to establish efficient resource allocation and investment strategies, while policymakers can utilize the results to guide policy and regulatory directions. Moreover, the study contributes to the existing body of knowledge by solidifying the framework of determinants for MASS adoption, incorporating commercial considerations alongside technical and legal factors. The results not only offer fundamental information for future research but also provide a rationale for informed decision-making in the shipbuilding and maritime industries regarding MASS adoption and operation.

This paper constructed the single country sequential dynamic CGE model to analyze the economic impacts of subsidizing water industry under the GHG emission abatement policy in Korea. We introduced the carbon tax to reduce the GHG emission and made two scenarios. One is to transfer the total tax revenue to household. The other is to mix the tax transfer and water industry support. Our Simulation results show that the macroeconomic effects might be positive by subsidizing water industry compared with the pure tax transfer. However, the support of water industry doesn't contribute to head for the non-energy intensive economy because it's economic activity highly depend on fossil energy and energy intensive products as intermediate demand. This means that it is important to make efforts on the cost effective measures such as energy technology progress, alternative energy development, and energy efficiency improvement in water industry against climate change policy.
