Purpose: Dairy marketing cooperatives operate in the agricultural sector of the Ethiopian economy and are supposed to increase the efficiency of the marketing system. This paper aims to study factors affecting the participation of farm households' in dairy marketing cooperatives. Research design, data, and methodology: The research has focused on one primary question. What are the possible factors that affect farm households' participation in dairy marketing cooperatives? The survey questionnaire was developed and an interview was made using enumerators. A total of 1500 sample households were selected randomly using the method of sampling with probability proportionate to size. Descriptive and inferential statistical analysis (binary logit model) was used for analysis. Results: The study result revealed that among thirteen explanatory variables hypothesized to affect dairy producer farmers' participation in dairy marketing cooperatives; eleven were found to be statistically significant. From these findings, it is observed that members of the dairy cooperatives have significant advantage over nonmembers. Conclusions: Both internal and external intervention measures are suggested. Internally, the cooperatives' board of directors should design appropriate strategies to attract nonmembers to improve future participation, and, externally, government, NGOs, and other stakeholders need to emphasize methods that increase nonmembers' participation in dairy marketing cooperatives.

The study aims to investigate differences between men and women in influence of various socio-demographic factors on choice of mode of transport. For this purpose, a binary logit model of choice probabilities is implemented on survey data of a developing country city. Results indicate women's choice of travel mode to be more environment-friendly than that of men. Well-educated, working and middle-aged individuals appear to be the most likely to choosing more-polluting modes of transport for frequent travelling purposes. Individuals in the sample who are the least socioeconomically well off are found the most likely to be promising for the environment. The findings of this study suggest the future transportation policies toward development of existing infrastructure of greener modes of transportation in the city such as, public transportation services and pedestrian lanes, so as to manage the rising issues of degrading environmental quality. The study highlights how the consideration and inclusion of socio-demographic factors is crucial for policy recommendation regarding curtailing the environmental damages contributed by transportation sector. Because mobility crucially affects all other indicators of empowerment, and women are the ones using green modes extensively, the city's transportation system should be so developed which gives their safety and security due importance.

Purpose - A traditional retail market is a place that offers economic opportunity to employees and employers alike it also is a place where the community can meet. The Korean government has invested three trillion won to improve physical and non-physical aspects in traditional retail markets since 2004. However, little research on this has been conducted. We explore this research gap that could lead to theory extension. We analyze consumption behavior with respect to traditional retail markets through an empirical analysis, thus overcoming limits in previous research. We empirically analyze policy effects of traditional retail market projects supported by the Korean government. Research design, data, and methodology - We propose a traditional retail market improvement plan via the relation between cause and effect resulting from the analysis. More specifically, logit analysis was carried out with 1,754 consumers in 16 cities nationwide. In order to analyze consumer consumption behaviors nationwide, the probability was analyzed using a logit model. This research analyzes the link between support and non-support by the Korean government using binary values. The dependent variable is whether Korean government support is implemented; the binomial logistic regression is used as the statistical estimation technique. The object variables are:1 (support) or 0 (nonsupport), and the prediction value is between 1 and 0. As a result of the factor analysis of questions related to attributes of service quality, four factors were extracted: convenience, product, facilities, and service. Results - The results indicate that convenience, product, and facilities have a significant influence on consumer satisfaction in accordance with the government's traditional retail market support. Additionally, the results reveal that convenience, product, facilities, and service all have a significant influence on consumer satisfaction in a traditional retail market's service quality and consumer satisfaction. Finally, the analysis indicates that the highly satisfied traditional retail market customer has a significant influence on revisit intention. Moreover, the results reveal that the highly satisfied traditional retail market customer has a significant influence on recommendation intention. Conclusions - This research focused on consumers nationwide to measure policy effects of traditional retail markets compared to previous research that focused on one traditional retail market or a specific area. We verified the relationship of service quality and customer satisfaction and consumer behavior based on service quality theory. The results indicate that consumer satisfaction of traditional retail markets supported by service quality factors has a significant impact. In a concrete form, the results indicate that these effects are from facility modernization projects and marketing support projects of the Korean government. The results also imply that these facility and management support effects from the Korean government have been consistent. We realize that the Korean government has to selectively support traditional retail markets in major cities and small and medium-sized cities. To that end, the Korean government needs to select a concentration strategy for the revitalization of traditional retail markets.

최근 제품과 서비스를 보호하고 차별화하기 위한 기업 경쟁력의 핵심 자원으로서 상표의 중요성이 증대되고 있다. 글로벌 기업들은 자사의 핵심가치가 투영된 브랜드 관리와 점차 빈발하고 있는 상표권 분쟁 대응을 위해 상표권 확보에 매진하고 있고, 창업기업과 개인은 안정적 사업 영위와 투자금 유치를 위해 상표권 확보에 매진하고 있다. 이러한 가운데 본 연구는 국내 벤처창업기업의 상표와 비즈니스 전략간 연관성 규명을 위한 실증분석을 실시한다. 분석데이터는 2021년 벤처기업정밀실태조사 중 2,230개의 법인기업 응답데이터가 활용되었고, 분석방법으로는 성향점수매칭법, 구조방정식모형분석, 이항로짓분석이 활용되었다. 분석 결과 국내 벤처창업기업의 상표 보유는 비즈니스 전략의 수준 측면에서 큰 차이를 만들지는 않는 것으로 확인되었다. 이는 국내 벤처창업기업의 상표는 주로 내부역량화 과정을 통해서만 비즈니스 전략을 고도화하는 반면 외부역량화 과정을 통한 비즈니스 전략 고도화는 매우 미미하기 때문인 것으로 확인되었다. 한편 벤처창업기업의 비즈니스 전략 수준 중 원가우위전략 수준이 상표 보유성향을 강화하는 것으로 확인되었는데 이는 원가우위수준의 완성도가 높아 지면 높아질수록 상표보유를 통해 제품·서비스의 안정적 판매·공급을 위해, 그리고 향후 고부가가치화로 전환하기 위해 상표보유를 확대하는 경향이 있음을 보여준다.

This study aims to analyze what factors are associated with child care accreditation in Chungbuk province. This study examined three questions about which factors influence the accreditation of childcare centers: 1) if they passed the accreditation criteria, 2) the total score on the accreditation criteria, and 3) the domain scores for the six domains of environment, management, process, interaction and teaching, health and nutrition, and safety. The characteristics of 1,212 childcare centers, the independent variables, were commit management, type, specialized service, maximum capacity of children, registration ratio, target age groups of children, duration, and city size. The formal expert committee evaluated objective scores for 952 childcare centers. I derived the data for this study from the i-sarang Childcare Information Portal site (http://info.childcare. go.kr/). Frequency, descriptive statistics, binary logit model, and OLS model analysis were used to examine the accreditation and scores by factors of childcare centers. The findings of the present study are as follows. First, about 80% of the 1,212 childcare centers in Chungbuk province were accredited. Second, the accreditation of the child care center was affected by the specialized service, registration ratio, and duration. Finally, the total score of accredited childcare centers was associated with the maximum capacity of children, registration ratio, and duration. The factors of childcare centers influencing sub-area scores were different by environment, interaction and teaching, health and nutrition, and safety. The present study is important because it offers preliminary data identifying accreditation characteristics that can judge problems related to the quality of service of childcare centers and suggest childcare policy implications.

중국은 2000년대 들어 '삼농(三?)'문제(농민, 농업, 농촌)를 국가 최우선과제로 추진하고 있다. '삼농'문제 해결책의 하나인 농지유동은 최근 10여 년간 급속히 성장하였다. 특히 농지유동을 추진함에 따라 농촌경제가 발전하였으며 동시에 농가 생활수준도 크게 개선되었다. 그러나 전포방식 위주의 농지유동유형은 농가의 농지유출 의욕을 저해하여 궁극적으로 대규모 농지유동의 저해요인으로 작용하고 있다. 본 논문은 중국 농가의 농지유동유형 영향요인과 농지유동가격 결정요인을 분석하였고, 그 결과를 토대로 다음과 같은 시사점을 찾았다. 첫째, 농가들이 입고방법으로 농지를 유출하도록 지도해야 하고; 둘째, 계약기간을 장기화해야 하며; 셋째, 작물별 농지유동 대응책을 마련해야 하고; 넷째, 농지유출 농가에 대해 교육프로그램을 구축해야 한다.
