Rural life improvement has remained a key policy concern for the governments of most developing countries. However, developing countries mostly focused on agricultural productivity and technology development while implementing rural development policies. This paper was aimed at constructing the trends and identify the major tasks implemented through the rural life improvement programs in Korea and describing rural development efforts in Ethiopia after the Second World War. The data was generated through an intensive review of literature and focus group interview in Korea. The two countries in general and their rural areas in particular, were poor and almost similar initially. While the condition of rural Korea rapidly transformed since 1960s, rural Ethiopia has not yet experienced major improvement. Although different rural development efforts have been made in Ethiopia, erratic policies implemented by the different political regimes across time emerge to be one of the main factors behind the poor performance of the of the rural sector. Further, while the Korean government's rural development policy gave equal emphasis to improvement of agricultural production base as well as rural life improvement right from its inception, the Ethiopian rural development policy has rather neglected the rural life improvement aspect. Diversification of rural economy was also another priority area in Korea's rural development policy through agro-processing, rural tourism, and non-farm employment opportunities whereas this has not been the case in Ethiopia's rural development policy. We suggest some lessons that Ethiopia might adapt for its rural life improvement endeavors.

Due to the 4th Industrial Revolution announced at the Davos Forum, the World Economic Forum, in 2016, industrial trends around the world are changing rapidly and intelligently. Among them, the digital twin is drawing attention from all industries as a groundbreaking technology that reduces unnecessary costs and trial and error by implementing real objects, systems, and environments in the same way in the real virtual world and using them to perform simulation analysis. In particular, there is a lot of interest in the application of digital twin technology in solving ports safety and efficiency challenges at once. However, there is a lack of in-depth research for the application of digital twin technology in the port, and in particular, there is a lack of research on measurable data for the implementation of the digital twin in ports. The purpose of this study was to increase granularity and connectivity through measurable data investigation for the application of digital twin technology at container ports. Based on the study results, data factors for container port application were classified into crane data, operational data, physical data, and transportation data, and factor composition, correlation with factors, and fitness were confirmed through confirmatory factor analysis.

This study analyzed Corporate Social Responsibility (CSR hereafter) of construction companies, especially focusing on small-medium companies. Surveys on construction companies' CSR activities and intensive interview with experts were executed to analyze and draw some implications. The empirical results shows that most of construction companies feel keenly necessity of CSR. The level of small-medium companies' awareness is lower than that of large companies'. CEO and board members of small-medium companies are less concerned about CSR yet. Carrying CSR activities co-working with NGO is preferred because of expertise and network. This study also suggests future strategy for CSR in the construction industry, focusing on small-medium companies. First of all it is necessary for small-medium companies to enhance the level of awareness and encourage participation in CSR. Second, it is required to strengthen relation with NGO and share information for CSR. Third, it is really significant to strengthen budget support and secure personnel to activate CSR. The systematic support by gevernment is also important. Lastly, it is essential to mount a publicity campaign and develop various CSR program. The role of 'Construction Industry Foundation for Social Responsibility' is emphasized because small-medium companies have very little room for CSR.

This study analyzed what consumer characteristics affect the experience of using overseas direct purchase at a time when the overseas direct purchase market is rapidly increasing and consumers' interest in overseas direct purchase is increasing accordingly. For the study, personal data from the 2022 Korea Media Panel Survey were used, and data from 6,734 people who responded "yes" or "no" to whether or not to use overseas direct purchase among 9,941 total respondents were used for analysis. In addition, three variables (demographic, media utilization status, values and lifestyle) were selected among the items of the Korea Media Panel Survey. First, general characteristics were analyzed fo 6,734 people, then, Chi-square test and t-test were performed for comparative analysis between each variable according to the use of overseas direct purchase. Finally, logistic regression analysis was performed to identify the factors affecting overseas direct purchase. As a result of the analysis, 4 out of 5 demographic variables, 2 out of 3 media utilization variables, and 3 out of 7 values and lifestyle variables were derived as decisive factors for using overseas direct purchase. These results can be used to establish marketing strategies that can increase the use of consumers through domestic shopping malls, such as providing differentiated services for the sale of overseas direct shopping products on domestic shopping sites.

Since the global financial crisis, major countries have been executing policies related to two top-priority goals to create more jobs: revitalization of entrepreneur activity and the cultivation of small and medium-sized companies. In South Korea, the interest of policy makers is increasingly focusing on the role of SMEs that have a technological competitive edge in the realization of a "job-centered creative economy." Due to the nature of the field, the health and medical industry requires a particularly long time until the achievement of industrialization, Also, because of the complex distribution structure, it is essential for related government ministries and institutions to jointly devise strategies. A lack of policy supports for the industry has thus far resulted in its development being relegated for the most part of small and medium-sized companies, which consequently means low global competitiveness. Now is the time for the South Korean government to provide the revolutionary supported options and strategies. This study aims to propose a general policy direction and policy areas for the cultivation of Korea's small and medium-sized companies in the healthcare industry into global small giant companies through an exploration of the German case. It is crucial to first cultivate the international competitiveness of Korean small and medium-sized companies (as in the case of Germany) so that they can grow into global small giant companies. Another important task is the creation of an environment that expedites the qualitative growth of promising SMEs as well as technological development. After securing competitiveness in terms of both product quality and technology in the global health market, substantive policy supports will be necessary to cultivate global small giant companies that are export-based (e.g. job creation effect, sales value added).

The number of people with disabilities is increasing recently in Korea, in particular the proportion of children with disabilities is approximately above 5%. While there are many studies focusing on satisfaction of payment policy due to increased concern about children with disabilities, the studies on comparison and the effect factor of user satisfaction depending on the cash and voucher are not sufficient. Based on the need to recognize and research this issue, the ultimate goal of this study is to lead to implications for the payment policy by investigating user satisfaction depending on the type of payment of policy on children with disabilities. The result that analyzes the effect of general characteristics on user satisfaction shows that in case of in-cash, children and the degree of disability affect user satisfaction. In the case of voucher, the gender of parents, the degree of disability and the average income affect it. The implication of this study suggests practical implication and policy implication. Implications of the study is that provide a customized service considering general characteristics. Second, It needs to extend the range of amount of payment of in-cash. Third, extend and pay the amount of in-cash, and the service of voucher. Fourth, provide low-income group(including public aid recipients and near poverty group) with voucher to ease financial burden.

The metaverse is a virtual world where individuals engage in social, economic, and cultural activities using avatars, which represent an alternate version of oneself within the virtual realm. While the metaverse has garnered global attention recently, research exploring the identity manifested through avatars within the metaverse remains limited. This study investigates the influence of four IT artifact characteristics related to avatar usage in the metaverse-avatar representation, avatar copresence, avatar profiling, and avatar-space interaction-on perceived avatar identity verification. A survey was conducted with 196 experienced users of the Zepeto platform, and hypotheses were tested using structural equation modeling. The analysis results indicate that the use of IT artifacts enabling avatar representation, avatar copresence, and avatar-space interaction has a positive impact on perceived avatar identity verification. This achieved self-verification indirectly influences the satisfaction and subsequent intention to continue using the metaverse. This study contributes to the academic field by empirically verifying the metaverse technological factors that influence the projected identity onto avatars within the metaverse. Furthermore, it is expected to provide effective guidelines for metaverse platform companies in designing and implementing the metaverse.

Existing studies on mixed ratings that combine ESG ratings and credit ratings have been rare. Through meta-frontier analysis, this study examines the relationship between the prime and non-prime groups in ESG ratings, credit ratings, and mixed ratings that consider ESG ratings and credit ratings at the same time. Efficiency was compared. Meta-frontier analysis was used to compare the efficiency of 143 listed manufacturing companies in Korea between the prime and non-prime groups based on the ESG ratings assigned to them by KCGS and the credit ratings assigned by Korea's three major credit rating agencies. As a result of this study, first, the meta-efficiency of the prime mixed-grade group was statistically more efficient than the non-prime mixed-grade group under the variable return scale (VRS) assumption. Second, the prime ESG rating group had a relatively higher proportion of scale inefficiency than the non-prime ESG rating group. Third, in terms of economies of scale, the prime credit rating group had a higher proportion of diminishing returns to scale (DRS) than the non-prime credit rating group. This study will help companies interested in sustainability management to do ESG management.

지속가능한 국가 발전을 위한 물관리 정책은 항상 국정 과제의 중심에 있다. 물관리는 수재해예방, 양질의 안정된 물이용, 충분한 식량생산, 수생태계와 물환경의 보호, 효과적 재정투자 등과 같이 다양한 분야에 계층적이면서도 상호연계성 있는 전문성을 요구한다. 동시에 물관리의 효과와 편익은 경제활동의 기반이 되고 환경보전의 원천이므로 정책의 수요는 정부뿐만 아니라 국민과 더불어 자연으로부터 기인한다. 특히 기후변화의 불확실성 또는 감염병 대발생과 국가적 위기에도 지속가능한 국가 발전을 이행하기 위해서는 시의성 있고 유효한 물관리 정책은 필수이다. 그동안 우리나라 물관리 정책의 세분화 또는 파편화는 물관리 전문성 강화의 효과보다는 비효율성의 결과를 더 크게 생산해 왔었다. 특히 부족한 협력과 조정은 과잉·중복 투자, 비일관적 정책, 비효율적 성과라는 왜곡된 통합물관리 정책 순환이 반복되게 하였다. 최근 정부는 국토교통부의 하천수량(홍수 포함) 및 광역상수도 관리 기능을 환경부로 이관하는 물관리일원화를 추진하여 통합물관리의 발판을 마련하는 계기를 달성하였다. 하지만 비록 정부조직법 개정과 물관리기본법 제정으로 통합물관리 정책의 틀은 마련되었으나, 국토교통부가 하천법 상의 일부 사무를 담당하므로서 하천관리 정책의 복잡성과 다원화는 높아졌다. 따라서 하천의 이용 및 관리에 관한 만족도, 관리주체, 미래상, 물관리일원화 후 정책수요, 기후변화에 관한 인식, 하천관리 참여 의향 등을 조사하는 연구는 시급한 실정이며 향후 하천기본계획, 생태하천복원사업, 소하천정비사업 등과 같은 재정사업의 추진 방향에도 매우 중요한 주제라고 할 수 있다. 본 연구에서는 현재와 미래 하천의 이용 및 관리, 그리고 정책방향에 대하여 일반 시민(4,500명)과 전문가(168명) 대상의 설문조사를 실시하였으며 인식의 공통점과 차이를 비교분석하였다. 설문조사의 내용은 3가지 부문(하천이용, 하천관리, 하천정책)으로 구분하여 각 부문별로 세부문항으로 구성하였다. 일반 시민과 전문가 간의 인식조사 비교 결과, 공통적으로 시민과 전문가는 하천의 바람직한 미래상으로 '깨끗한 수질의 하천'을 가장 높게 선호하였다. 하천관리 우선순위를 묻는 질문에 대한 시민과 전문가의 응답도 대하천, 도랑이나 개울, 중하천, 소하천 순으로 동일하였지만, 1순위와 2순위의 격차는 시민(26.1%)보다 전문가(1.2%)가 낮았다. 또한 시민과 전문가는 하천관리의 주체로 '물전문기관'을 가장 높게 선호하였지만, 전문가는 '물전문기관' 다음으로 중앙부처(20.2%)를 선호하였지만, 시민은 중앙부처(6.8%)를 가장 선호하지 않는 하천관리 주체로 응답하여 두 집단 간의 큰 인식의 차이를 알 수 있었다. 물관리일원화 후 보다 큰 관심을 가져야할 정책으로는 '건강하고 깨끗한 수질'을 시민(38.9%)과 전문가(47.0%)는 1순위로 선택하였으나, 2순위는 시민은 '생태서식공간'(11.6%)을 전문가는 '안정적 수량확보'(20.2%)를 선택하여 두 집단의 인식 차이가 있음을 알 수 있었다.
