As workplace incidents has been being declining in Korea, there is criticism of the effectiveness of occupational safety policy implementation. It is unknown that which policy target group needs to be targeted to yield effective injuries prevention. The purpose of this paper is to analyze and reveal the policy intervention group with a high priority in terms of industrial incident prevention and the related investment cost. A Policy Priority Model(PPM) is composed of 6 indicators regarding influences of both the incident reduction and the cost reduction. Z-score analyses are used to confirm the high policy priority area or policy target group. Overall, workplace with worker below 50 persons, construction site with the sales of more than a hundred million won, workplace with relatively small percentage of female employees and relatively higher percentage of older worker should be prioritized to reduce workplace injuries. This paper provides an analytic way that can be used to decide the policy priority workplace in order not only to reduce work-related injuries&illnesses and the related investment cost but to further lessen the related societal costs.

항공기 설계검증 체계를 갖추기 위한 투자 및 인프라개발, 그리고 이 과정에 동반되는 항공기개발의 경제적인 타당성을 분석하였다. 투자와 항공기 양산판매만을 고려한 현금흐름분석에서는 음의 순현재가치가 산정되어 경제적 타당성이 부인되었으나, 수출효과, 수입대체효과 및 사고감소효과를 감안할 때에는 순편익이 투자액의 3-5배에 달하는 것으로 평가되었다. 편익의 전유성이 매우 낮다는 점을 감안할 때 이 투자는 정부가 주체가 되어 실행하여야 하며, 재정지출의 경제적 타당성이 충분한 것으로 확인되었다.

In the era of the 4th Industrial Revolution, the importance of information protection is increasing day by day with the advent of the 'hyper-connection society', and related government financial investment is also increasing. The source of the government's fiscal investment projects is taxpayers' money. Therefore, the government needs to evaluate the effectiveness and feasibility of the project by comparing the public benefits created by the financial investment projects with the costs required for it. At present, preliminary feasibility study system which evaluates the feasibility of government financial investment projects in Korea has been implemented since 1994, but most of them have been actively carried out only in some fields such as large SOC projects. In this study, we discuss the feasibility evaluation of public projects for the purpose of information security. we introduce the case study of the personal information protection program of Korean public institutions and propose a cost-effectiveness analysis method that can be applied to the feasibility study of the information protection field. Finally, we presented the feasibility study and criteria applicable in the field of information security.

Purpose: This study explores the level of relevance of liability of foreignness (LOF) in foreign firms' decision to relocate or to expand their regional headquarters (RHQ) in Singapore. Research design, data and methodology: The research question is: what are the mitigating factors of LOF for RHQs operating in Singapore? This explorative study uses various resources from the government agencies: Singapore Economic Development Board such as annual reports between 2012 and 2022, investment programs and published interviews with RHQ's CEOs, Singapore Department of Statistics such as economic, socio-economic and investment data. Results: My study shows that years of nation-building toward a world-class infrastructure, identifying key-industries and conscientiously enhancing workforce skills and competency, developing and reviewing investment programs to attract and retain RHQs were the mitigating factors of LOF. Conclusion: This implies a low level of relevance of LOF in foreign firms' strategic choice to relocate or to expand their regional headquarters to Singapore. As such, the steady growth of multinational enterprises' (MNEs) RHQs in Singapore presents a challenge to the theoretical postulation of LOF positing that foreign firms are discriminated in host country-environment. As a result, incurring additional costs operating in an unfamiliar environment manifested by varying responses from the local actors. Singapore is a case in point.

No one doubts that textile and apparel industries have contributed to economic miracles of the export-led growth in Korea. However, by the turning of 1990′s, these sectors have encountered many problems such as decreasing of domestic production and exports mainly due to wage rise and shortage. Therefore, foreign direct investment to the low labor cost countries has been enlarged for a way of improving its competitiveness and increasing exports. However, no intensive study has been made exploring current investments and future directions. This study focuses Vietnam as one of the promising overseas investment countries. The purposes of this study are to analyze current investment status of Korean textiles and apparel firms in Vietnam, to explore merits and problems Vietnam has, and to present useful implications and strategies for Korean textiles and apparel companies. Analysis of current secondary data suggests that Korean apparel industry, rather than textiles industry, have invested more in Vietnam, mostly in southern Ho Chi Minh City. Investments of Korean apparel and textile firms have shown steady increase from 1990 but have turned to a decrease from 1995. Findings suggested that Vietnam has merits for attracting foreign investment since it provides relatively cheap labor and outstanding skillful hands suitable for apparel and textiles industries. In addition, because of EU quota increase and the trade agreement between Vietnam and USA it is likely for firms in Vietnam to increase exports to EU and USA Rapid expansion of domestic apparel market and "Korean trend (Han Rue)" in Vietnam resulted from successful star marketing of Korean firms are another merits Vietnam has to the Korean fm. However, regulations of central government, low efficiency of bureaucratic and stiff administrative process, difficulty of making decision in case of joint venture, lack of social overhead capital, high factory construction costs, weak construction condition, and the excessive competition among investment enterprises have found to be problems. Based on pros and cons of investment to Vietnam, marketing strategies, practical implications and future directions were suggested.

Thorium ($^{232}Th$) is four times more abundant than uranium in nature and has become a new important source of energy in the future. This is due to the ability of thorium to undergo the bombardment of neutron to produce uranium-233 ($^{233}U$). The aim of this study is to investigate the production cost of thorium oxide ($ThO_2$) resulted from the thorium extraction process. Four main parameters were studied which include raw material and chemical cost, total capital investment, direct cost and indirect cost. These parameters were justified to obtain the final production cost for the thorium extraction process. The result showed that the raw material costs were $63,126.00 - $104,120.77 (0.5 ton), $126,252.00 - $178,241.53 (1.0 ton), and $1,262,520.00 - $1,782,415.33 (10.0 tons). The total installed equipment and total cost investment were estimated to be approximately $11,542,984.10 and $13,274,431.715 respectively. Hence, the total costs for producing 1 kg $ThO_2$ were $6829.79 - $6911.78, $3540.95 - $3592.94, and $501.18 - $553.17 for 0.5, 1.0, and 10.0 tons respectively. The result concluded that with higher mass production, the cost of 1 kg $ThO_2$ would be reduced which in this scenario, the lowest production cost was $$501.18kg^{-1}$-$$553.17kg^{-1}$ for 10.0 tons of $ThO_2$ production.

This paper is to study globalization motives and strategies of Japanese and Korean industries by analyzing the causes and patterns of foreign direct investment (FDI) of the firms of the two countries during the 1980s and 1990s. First we develop a FDI function from the profit maximizing model of firms. Then we use regression analysis to determine internally driving-out factors and externally-inducing factors. Japanese FDI strategy has gone through three different stages; from natural resource-seeking investment in the 1950s and 1960s to market-expansion investment in the 1970s and 1980s and to a combination of cost-reducing (low-cost labor-seeking) investment and market-penetrating investment in the 1990s. On the other hand, Korean FDI behavior has gone through four different stages; from the learning stage with small investments in the 1970s, to natural resource-seeking investment in the early and mid 1980s, to the growth stage in the late 1980s and the early 1990s, to the maturity stage of the mid and late 1990s. The last two stages were characterized by a combination of cost-reducing investment and market-seeking investment. As a late comer, Korea began its FDI two decades later than Japan, but caught up the patterns of Japanese FDI by the mid 1990s and is in a competing position with Japan. Our findings show that both Japanese FDI and Korean FDI in Asia and other developing countries tendto be in labor-intensive sectors where their firms are losing their comparative advantages at home. The main motive for FDI into these regions is low-cost resource seeking. On the other hand, both Japanese FDI and Korean FDI in the U.S. and Europe tend to be knowledge-intensive sectors where Japanese and Korean firms attempt to internalize transaction and information costs by globalizing its production. The main motive for FDI into these regions is market-seeking. Firms in both countries have increased their investments in Mexico and Western and Eastern Europe in order to penetrate large economic blocs such as the EU and NAFTA area. Korean firms are more aggressive in expanding into new and untested markets than are their counterpart in Japan. Evidence of this can be seen in the scarcity of Japanese FDI and abundance of Korean FDI in Eastern Europe and China.
