This quantitative study aims to examine the effect of family ownership on company performance empirically. Specifically, this study examines the moderating effect of corporate governance on the relationship between family ownership and company performance which has never been explored in the previous studies. This study's main target population was all listed companies in the Indonesian Capital Market Directory (ICMD) for 2008-2018. The study used criteria, namely data completeness, to measure research variables and obtained 2996 data or firm-year observations. The research contingency model to test the proposed hypothesis was the General Moment Method (GMM). The study presents the results of data descriptions shows the average, median, maximum, minimum, and standard deviation values for each variable. The descriptive data shows that family ownership is common in Indonesia: 64% of 244 companies in the sample. The inferential analysis results using a multiple regression model test show that family ownership significantly reduces company performance. However, corporate governance proxied by the board of directors, managerial risk profile, and independent commissioners significantly moderate the relationship between family ownership and company performance. Besides, the managerial risk profile and independent commissioners strengthened while the board of commissioners' presence weakened the effect of family ownership on performance.

The purpose of this paper is to examine the use of material flow cost accounting (MFCA) in Vietnam's coal-fired thermal power plants. This study is based on the contingency and system theories to explain the application of management tools and analyze steps of input, output, and process in manufacturing. Costs in producing process-based MFCA include material cost, energy cost, system cost, and waste management cost. The exploratory case study methodology is used to describe and answer two questions, namely "How coal flow cost is recognized?" and "Why waste in material consumption can be harmful to the environment?". By analyzing the Quang Ninh and Pha Lai coal-fired thermal power plants that are the typical plants, this paper identifies the flow of primary material in these plants as a basis for determining losses for the business. The material flow of coal-fired thermal power plants provides the basis for the use of the MFCA. The manufacturing of electrical items in these plants is divided into four stages, each with its own set of losses. As a result, some phases in the application of MFCA are suggested, as well as some other elements required for MFCA application in coal-fired thermal power plants.

Recently, the Korean government has been actively promoting the smart city as their strategic agenda. However, to build smart cities that are greener, the authors believe it is essential to rapidly transit conventional energy sources such as fossil fuels to renewable energy. Although there is a big potential for Offshore wind in Korea, there has not been a full-scale commercial offshore wind farm until today. Since Korea is relatively a new market compared to the EU, it can be risky for developers. The authors will introduce risk management best practices in the offshore wind industry applicable to the Korean environment. This paper will mainly introduce an offshore wind project size of 99 MW. The project is expecting a Finance Close (FC) in Q3 2022, so the project team has prepared a risk register with over 150 risks and levers throughout the project lifecycle. Overall risks include risks with Development Expenditure (DEVEX) impact, a Capital Expenditure (CAPEX) impact, and an Operating Expenditure (OPEX) impact. Based on the identified risks, a more qualitative assessment of Cost and Schedule Impact was conducted. In conclusion, a Monte Carlo simulation was performed to propose a quantitative risk assessment to evaluate a benchmark contingency of the project cost.

Although the NutriPlus program has shown considerable evidence of enhancing users' nutritional status, the budget does not cover all eligible mothers and children. This study aimed to conduct a cost-benefit analysis of the NutriPlus program to assess its economic efficiency. 53 families with 79 users in the NutriPlus program at Daejeon Dong-gu Health Center participated in this study with informed consent. The costs and benefits were estimated from both the administrator's and users' perspectives. We converted the time cost into Korean currency based on the minimum wage in 2014. The value of nutrition education and service (B2), estimated by contingency valuation method (CVM), was counted as an economic benefit. 6 families (11.3%) were recipients of national medical care and 22 families (41.5%) paid 10% of the food package cost by themselves. The total cost was \7,450,167 and the total benefit was \12,402,239. The budget for the health center (C1+C2+C3+C4) was \5,984,381 a month. Time and transportation cost for receiving nutrition education (C6) differed significantly according to the economic status of families. Household food consumption increase (C4-B4) was 40,379 in the poverty group, which was four times more than in the other groups. The net benefit (B-C) was \4,852,172 and the B/C ratio was 1.66. Therefore, the NutriPlus program is beneficial in the economic aspect as well as in the nutritional aspect. If the enhancement of nutritional status was also considered, the total benefit would be even higher. These results confirm the legitimacy of a secure budget for the NutriPlus program. And we suggest expanding its budget to cover more eligible individuals to improve people's health and welfare.

Purpose: There is little controversy that a classic indication such as hemodynamic instability or any sign of peritoneal irritation requires an immediate laparotomy in the management of abdominal stab wounds. However, omental herniation or bowel evisceration as an indication for an immediate laparotomy is controversial. The purpose of this study was to evaluate the significance of these factors as indications for an immediate laparotomy. Methods: The medical records of 98 consecutive abdominal stab wounds patients admitted to the Emergency Center of Masan Samsung Hospital from January 2000 to December 2006 were carefully examined retrospectively. Using multivariate logistic regression analysis, thirty-nine factors, including the classic indication and intraabdominal organ evisceration, were evaluated and were found to be associated with a need for a laparotomy. Also, the classic indication was compared with a new indication consisting of components of the classic indication and intra-abdominal organ evisceration by constructing a contingency table according to the need for a laparotomy. Results: Multivariate logistic regression analysis revealed any sign of peritoneal irritation, base deficit, and age to be significant factors associated with the need for a laparotomy (p<0.05). The sensitivity, specificity, and accuracy rates of the classic indication were 98.6%, 72.0%, and 91.8%, respectively, and those of the new indication were 93.2%, 84.0%, and 90.8%, respectively. The differences in those rates between the above two indications were not significant. Conclusion: Intra-abdominal organ evisceration was not a significant factor for an immediate laparotomy. Moreover, the new indication including intra-abdominal organ evisceration was not superior to the classic indication. Therefore, in the management of abdominal stab wounds, the authors suggest that an immediate laparotomy should be performed on patients with hemodynamic instability or with any sign of peritoneal irritation.

This study was conducted to evaluate usefulness of numerical weather prediction data generated by the Unified Model (UM) for plant disease forecast. Using the UM06- and UM18-predicted weather data, which were released at 0600 and 1800 Universal Time Coordinated (UTC), respectively, by the Korea Meteorological Administration (KMA), disease forecast on bacterial grain rot (BGR) of rice was examined as compared with the model output based on the automated weather stations (AWS)-observed weather data. We analyzed performance of BGRcast based on the UM-predicted and the AWS-observed daily minimum temperature and average relative humidity in 2014 and 2015 from 29 locations representing major rice growing areas in Korea using regression analysis and two-way contingency table analysis. Temporal changes in weather conduciveness at two locations in 2014 were also analyzed with regard to daily weather conduciveness (C_i) and the 20-day and 7-day moving averages of C_i for the inoculum build-up phase (C_inc) prior to the panicle emergence of rice plants and the infection phase (C_inf) during the heading stage of rice plants, respectively. Based on C_inc and C_inf, we were able to obtain the same disease warnings at all locations regardless of the sources of weather data. In conclusion, the numerical weather prediction data from KMA could be reliable to apply as input data for plant disease forecast models. Weather prediction data would facilitate applications of weather-driven disease models for better disease management. Crop growers would have better options for disease control including both protective and curative measures when weather prediction data are used for disease warning.

In this study, a correlation between execution of quality management activities and their results was verified by applying the Malcolm Baldrige model (hereafter referred to as the MB model) as a quality management performance measurement indicator for small and medium enterprises (SMEs) in South Korea. To achieve this goal, we need to determine whether the categorical requirements in the MB model are recognized consistently in SMEs, as a prerequisite. To this end, factor analysis was conducted for measurement variables in each category, which revealed that the process indicator was made up of six factors and the outcome indicator was made up of five factors, like those configured in the MB model. This result can be interpreted to mean that the requirements in each category of the MB model were well produced and recognized consistently throughout SMEs in South Korea. In addition, the analysis of causality between the process indicator (quality management activities) and the outcome indicator (management results) showed high causality between them. Although the quality management levels of SMEs in South Korea are inferior to those of conglomerates or other national quality award-winning companies, this study is significant in that the causality between quality management activities and results was verified, since this study targeted SMEs in South Korea as the target of investigation. Thus, it is empirically proven that the MB model can contribute to improved management results for SMEs in Korea.

The objective of this study were 1) to determine the stages of concern of HE teachers about the practical problem-based curriculum approach, as illustrated by the Ohio's Work and Family Life Curriculum (W&FLC); 2) to determine the relationships between home economics (HE) teacher's stages of concern about W&FLC and personal and professional characteristics of HE teachers; and 3) to determine aspects of interest about the practical problem-based curriculum approach, such as the Ohio W&FLC. Respondents in this study were 225 HE teachers. The data were collected during the in-service teacher training sessions after presentation about W&FLC. Concerns Based Adoption Model (CBAM) was modified to provide a conceptual framework for this study. Frequencies, SD, mean, mode, range were used to determine the stages of concern of HE teachers. To determine the relationships between stages of concerns and personal and professional characteristics of HE teachers, coefficient of Chi-Square contingency tables was used. Content analysis was used to determine aspects of interest about the practical problem-bsed curriculum approach, such as W&FLC. The median of the stages of HE teachers' concerns about W&FLC was Stage 1, Information Stage. About 60% of HE teachers were interested in learning more details about W&FLC. Chi-square revealed no statistically significant relationships between stages of concerns about W&FLC and characteristics of HE teachers. Content analysis was used to determine aspects of interest about W&FLC of HE teachers. Nine categories were found: content, teaching strategies, implementation of the curriculum, philosophical framework, how to adopt W&FLC, resource materials, students' outcomes, in-service teacher training, and HE teacher organization. The majority of HE teachers were interested in relationships with family and others, resource management, family relationships, personal development, communication skill, family life, creating a self-identity, life planning, roles of family members, homemaking management, child care, and parenting.
