  • Purpose - The purpose of this study was to examine the relationship between CEO name uncommonness and R&D intensity while focusing on CEO ownership and CEO tenure as moderators of the relationship. Design/methodology/approach - This study collected data from various American databases such as national data on given names from Social Security Administration, COMPUSTAT, and Execucomp. The sample of this study includes 2,494 (firm-year) observations from U.S. firms between 2005-2011. This study conducts Feasible Generalized Least Square (FGLS) regression analysis to test the hypotheses. Findings - First, we found CEO name uncommonness was positively related to R&D intensity. In other words, CEOs with unusual names prefer being distinctive by increasing R&D investments. Second, we examine the moderating roles of CEO characteristics (i.e., CEO ownership and tenure). The results show that CEO tenure strengthens the positive relationship between CEO name uncommonness and R&D intensity. Research implications or Originality - First, this study extends the CEO characteristics and R&D literature by investigating how CEO name uncommonness affects R&D intensity. In addition, our study also supports the intitutionalization of CEO power arguments by showing that CEOs with unusual names are more likely to pursue distinctive strategies when they have longer tenure. For practical implications, our results allow the investors to better predict corporate future R&D expenses. It suggests that ceteris paribus, CEOs with unusual names, vis-a-vis CEOs with common names, are more likely to increase R&D expenses.

  • Pig production is one of the viable enterprises of the livestock sub-sector of agriculture. It contributes significantly to the economy and animal protein supply to enhance food security in Africa and globally. This article explored the present status of pig production in Africa, the challenges, prospects and potentials. The pig population of Africa represents 4.6% of the global pig population. They are widely distributed across Africa except in Northern Africa where pig production is not popular due to religio-cultural reasons. They are mostly reared in rural parts of Africa by smallholder farmers, informing why majority of the pig population in most parts of Africa are indigenous breeds and their crosses. Pig plays important roles in the sustenance of livelihood in the rural communities and have cultural and social significance. The pig production system in Africa is predominantly traditional, but rapidly growing and transforming into the modern system. The annual pork production in Africa has grown from less than a million tonnes in year 2000 to over 2 million tonnes in 2021. Incidence of disease outbreak, especially African swine fever is one of the main constraints affecting pig production in Africa. Others are lack of skills and technical know-how, high ambient temperature, limited access to high-quality breeds, high cost of feed ingredients and veterinary inputs, unfriendly government policies, religious and cultural bias, inadequate processing facilities as well as under-developed value-chain. The projected human population of 2.5 billion in Africa by 2050, increasing urbanization and decreasing farming population are pointers to the need for increased food production. The production systems of pigs in Africa requires developmental research, improvements in housing, feed production and manufacturing, animal health, processing, capacity building and pig friendly policies for improved productivity and facilitation of export.

  • Widespread damages from extreme winds have attracted lots of attentions of the resilience assessment of power distribution systems. With many related environmental parameters as well as numerous power infrastructure components, such as poles and wires, the increased challenge of power asset management before, during and after extreme events have to be addressed to prevent possible cascading failures in the power distribution system. Many extreme winds from weather events, such as hurricanes, generate widespread damages in multiple areas such as the economy, social security, and infrastructure management. The livelihoods of residents in the impaired areas are devastated largely due to the paucity of vital utilities, such as electricity. To address the challenge of power grid asset management, power system clustering is needed to partition a complex power system into several stable clusters to prevent the cascading failure from happening. Traditionally, system clustering uses the Binary Decision Diagram (BDD) to derive the clustering result, which is time-consuming and inefficient. Meanwhile, the previous studies considering the weather hazards did not include any detailed weather-related meteorologic parameters which is not appropriate as the heterogeneity of the parameters could largely affect the system performance. Therefore, a fragility-based network hierarchical spectral clustering method is proposed. In the present paper, the fragility curve and surfaces for a power distribution subsystem are obtained first. The fragility of the subsystem under typical failure mechanisms is calculated as a function of wind speed and pole characteristic dimension (diameter or span length). Secondly, the proposed fragility-based hierarchical spectral clustering method (F-HSC) integrates the physics-based fragility analysis into Hierarchical Spectral Clustering (HSC) technique from graph theory to achieve the clustering result for the power distribution system under extreme weather events. From the results of vulnerability analysis, it could be seen that the system performance after clustering is better than before clustering. With the F-HSC method, the impact of the extreme weather events could be considered with topology to cluster different power distribution systems to prevent the system from experiencing power blackouts.

  • This study was analyzed by comparing it with paid-employed to understand the mental health level of self-employed people during the COVID-19 pandemic. The subjects of this study were 6,736 self-employed and 15,196 paid-employed using the 6th data of the Korean Working Conditions Survey(2020-2021). As a result of the study, self-employed people are more anxiety(F=-2.81, p=0.001) than paid-employed. Sleep disorders (F=-18.05, p=2.035), and depression levels(F=19.80, p=1.176) were all high, and the positive perception of subjective health(F=29.70, p=1.020) was also lower than that of paid-employed. Therefore, it is suggested that long-term and practical government policy and social security systems are needed for groups particularly disadvantaged by COVID-19.

  • This study analyzes the development process of Environmental, Social, and Governance (ESG) policies in Korea and corporate response strategies, comparing them with cases from major countries. The results show that while Korea has established a basic framework for ESG policies through the K-ESG guidelines and plans for mandatory ESG disclosure, these policies lack the specificity and enforceability seen in major countries. In terms of corporate response, large companies are actively formulating ESG strategies, but strengthening ESG capabilities of small and medium-sized enterprises (SMEs) remains an urgent task. Industry-specific ESG strategies reflect the characteristics of each sector, such as carbon neutrality in manufacturing, expansion of responsible investment in finance, and enhanced data security in IT. This study suggests improving Korean ESG policies by enhancing the alignment of ESG disclosure standards with international norms, strengthening tailored support for SMEs, and developing industry-specific policies. For effective corporate ESG response, the study proposes strategic integration of ESG, enhanced communication with stakeholders, and improved ESG data management capabilities.

  • Today, over seventy five percent of nursing in Korea provide a psychiatric experience in the basic curriculum. The psychiatric affiliation presents numerous major problems of adjustment to the student. The Importance of positive attitude toward the nursing care of psychiatric patients is recognized by the nursing profession. I have fined out the unfavorable attitude of non collegiate nursing students toward psychiatric nursing affiliation by previous research. This study was undertaken in response to a felt need to explore the use of several devices which might yield information about attitudes toward psychiatric nursing as a basis for future planning of the program offered at a selected hospital. This study is designed to meet the following objectives; (1) In order to find out the expressed attitudes of fifty·three collegiate nursing students toward their psychiatric affiliation. (2) To compare responses given by selected group of collegiate and non collegiate nursing students to same questionnaire (3) To determine the relationship between the attitudes of nursing students toward psychiatric nursing and the type of instructions where experience was obtained. A questionnaire, a Korean translation of the "Psychiatric Nursing Attitude Questionnaire" by Moldered Elizabeth fletcher, was administered to fifty-three collegiate nursing students who had completed a four-week psychiatric affiliation in a S hospital psychiatric ward during May 7, 1973 to Dec. 16, 1973. - The questionnaire of 100 statements was administered in the following way; (1) Part Ⅰ, Preconceptions, was, given in individual conferences with each subject, during the first few days of their affiliation, and again during the final week of affiliation. The responses to Part I were oral. (2) Part Ⅱ, Expectations, Part Ⅲ, Personal Relations, Part Ⅳ, Personal Feelings, and Part V, Attitudes and Activities of Patients were given to all of the subjects in a group meeting during the second week of the affiliation, and again, during the fourth week at the termination of the affiliation. Responses to Parts Ⅱ, Ⅲ, Ⅳ·, and V, were written. Each of the 100 statements of the questionnaire was considered to be either Positive or Negative. A favorable response was assigned the positive value of 1 and an unfavorable response was assigned the Negative value of O. The coefficient of correlation was computed between the two sets of scores for the fifty-three nursing students, The mean score, the standard deviation, and the differences in the means on each of the five parts of the questionnaire were computed and the relationships calculated by at-test. The results of the study were as follows; 1. There was no significant correlation between the two sets of the scores for the fifty-three nursing students during the four-week psychiatric affiliation. (r= 0.36) 2. There was no significant difference in the mean scores between the first and final tests for any of the questionnaire. 3. The Part Ⅰ, Preconceptions, data indicated collegiate nursing students have positive attitudes in preconceptions than non collegiate nursing students and preconceptions toward the psychiatric affiliation which affect their psychiatric nursing experience. 4. The Part Ⅱ, Expectations, data indicated more appropriate expectations of collegiate nursing students related to pre psychiatric affiliation orientation and sufficient theory learning than non-collegiate nursing students. 5. The Part Ⅲ, Personal relations, data indicated some students have negative attitudes in personal relations with normal people in respect to psychological security and social responsibilities. 6. The Part Ⅳ, Personal feelings, data indicated nursing students have psychological insecurity & inappropriateness. 7. The Part V, Attitudes and activities of patients, data indicated collegiate nursing students have more positive attitudes to the psychotic behavior of certain situations due to sufficient theory learning. 8. The data indicated collegiate·nursing students have more positive attitude than non-collegiate nursing students. 5. The Part Ⅲ, Personal relations, data indicated some students have negative attitudes in personal relations with normal people in respect to psychological security and social responsibilities. 6. The Part Ⅳ, Personal feelings, data indicated nursing students have psychological insecurity & inappropriateness. 7. The Part V, Attitudes and activities of patients, data indicated collegiate nursing students have more positive attitudes to the psychotic behavior of certain situations due to sufficient theory learning. 8. The data indicated collegiate·nursing students have more positive attitude than non-collegiate nursing students through psychiatric affiliation.

  • Objectives: This purpose of this study was to make clear the fitness to data of the causality model related to father's child-rearing participation in a double-income household. Methods: Subjects of this survey consisted of the fathers of 2,006 households that use 21 day-care centers and 4 kindergartens whose cooperation was received via the city government departments that have jurisdiction over day-care centers and kindergartens in cities A and B in prefecture I and in city C in prefecture II (city A: 499 households; city B: 1,113 households; city C: 988 households). The surveyed items consisted of the father's age, the father's educational history, the number of children, the age of the youngest child, the father's parental-role awareness, the father's daily working hours, the father's return-home time, and child-rearing participation by the father. Results: The fit indices were found to be CFI = 0.912, GFI = 0.948, and RMSEA = 0.082. Regarding the path coefficients, the path coefficient of the pathway from the age of the youngest child to the father's parent positivity (0.08) and the path coefficient of the pathway from the father's parent positivity to child-rearing participation (0.19) were both at statistically significant levels. Also, the father's return-home time and the working hours, which were considered as disincentives exhibited a direct effect on child-rearing participation without being influenced by the father's parent positivity or parent negativity. The path coefficient of the pathway from return-home time to child-rearing participation was -0.43, and the path coefficient of the pathway from working hours to child-rearing participation was -0.13. The value of the path coefficient expressing the relationship between the return-home time and working hours was 0.80. Conclusion: Authors infered that it'll be the basic material to build a generation mechanism about vanity and father's child-rearing participation appropriately as a result of this research.

  • The school is committed to the role of public education for the effective development of student academic achievement and intellectual ability. It is also a space to expand the range of care and understanding for others with as a member of the academic community as well. However, the reality of our country schooling has been pointed out that if a lot about the lack of character education related to the attitude of life care for others and feel a sense of responsibility. An individual is not necessarily emotional intelligence There are side out, as well as grow into adults, schools are obliged to teach a variety of methods associated with it. Nevertheless, education is not of the country beyond the formal excessive administrative work or other activities due to the process of character education to neglect, including the work of teachers. Therefore, students brought the expansion of the act that should not, and eventually lead to serious social issues that directly harm others, such as school violence. Therefore, students brought the expansion of the act that should not, and eventually lead to serious social issues that directly harm others, such as school violence. This study is based on an act of juvenile delinquency and criminology education was to refine the concept of toughness and validate the relationship between school violence through empirical research. Accordingly, from July 1, 2013 September 31, 2013 to 277 high schools across the country are attending the third year of the schools available for non-response and analysis of the students who participated in the admission and simulated typical presentation of K University in Gyeonggi-do not judge students in the final analysis, except for the data and data from a total of 1045 patients were utilized. As a result, many schools have experienced violence, male student work can be applied to a lot of rock school violence was experienced. Also, a lot of experience can be applied to a healthy student rock school violence, anger-control and empathy, this is considered a low student showed consciousness experienced school violence exerted.

  • This study analyzed safety management system against disasters perceived by local residents of Chungcheongbuk-do and then examined the policy directions to be considered in order for local governments to improve the safety level of residents and build an effective safety management system against disasters. The findings were as follows. First, in their recognition of risks of safety against disasters, recognition on the possibility of the occurrence of natural disasters was higher than that of social disasters or safety accidents. Secondly, also in the aspect of the importance of category of safety management against disasters, they recognized that of natural disasters far higher than others. Third, they showed satisfaction higher than average with basic job performance of local governments related with safety management, whereas they showed relatively less satisfaction with the aspects of check and publicity of risk factors, and short-term restoration system out of phased job performance. Fourth, in the aspect of capability of local governments for safety management against disasters, they rated positively capability of the responsible departments and the professionality, whereas they relatively underestimated the scale or budget of safety-related organizations. Fifth, the policy directions to be taken for safety against disasters by local governments included strengthening of regular education like experience-based training, expansion of education among local residents, more support for relevant facilities and resources, activation of residents-participating campaigns, improvement of apparatus and personnel treatment related with firefighting and security, frequent patrol and oversight, more exercises against disasters. So, to strengthen safety management system against disasters in local governments and build a effective responding system may need to extend programs assisting vulnerable class to safety against disasters, build a community-friendly safety management system, extend the cooperation system by participation of residents, enhance collaboration and support system with safety-related bodies like police, firefighters.
