The purpose of this study was to identify the factors affecting mental health status according to gender of persons with physical disabilities and to try their healthy life. Using the 6th Korean Retirement and Income Study, 333 persons with physical disabilities were included in the study. Descriptive statistics, t-test, and regression analysis were conducted to examine the general characteristics, instrumental activities of daily living, material support, and the effects on mental health status. There was no statistically significant difference in mental health status by gender, but there was a difference in Instrumental Activities of Daily Living and life satisfaction. In the case of males, instrumental daily activities performance, material support, depression, and life satisfaction were found to be influential. In the case of females, spouse, depression, and life satisfaction were factors affecting mental health status. Based on the results of this study, we will be able to understand persons with physical disabilities and use them as a basis for developing mental health promotion programs.

This study examines the mediating effects of social support on the relationship between health status and depression of the elderly in Korea. Through stratified multi-state random sampling, 1409 individuals aged 65 and over who lived in Seoul and Chunchen, and who had their own children were selected. Social support was composed of three types: emotional support, instrumental and financial support, and included both support-received from and provided to children. The multiple regression model proposed by Kenny and Baron was used. As the results, first, the elderly get more depressed when having lower health status and lower social support. Second, there is a partial mediating effect of social support in association with health status and depression. Comparing by gender, instrumental support received from children, and emotional and instrumental support provided to children are mediators in the link between health status and depression in the case of male. In the case of female, emotional, instrumental and financial support received from children, and instrumental and financial support provided to children shows the mediating effects between health status and depression. The results suggest that social support both received from and provided to children reduces the negative impacts of health status on depression of the elderly in Korea.

This study surveyed the elementary school teachers' use of visual representations and their perceptions of the functions of visual representations in the teaching of electricity unit. A total of 110 elementary teachers who have experiences in teaching electricity unit responded to online survey. The result showed firstly that most of the teachers use visual representations in their teaching and it is mostly limited to those presented in textbooks or images that they can get easily from internet search. Secondly, elementary teachers thought that they have high ability in using visual representations and low ability in understanding students' visual presentation ability. Thirdly, visual representations are more often preferred to be used as teacher-centered ways than student-centered ways for motivating students and conceptual understanding. However, in case of scientific inquiry, both teacher-centered and student-centered ways were equally preferred. Lastly, the teachers' perceptions of the functions of visual representations were categorized into 'teaching-instrumental function', 'learning-instrumental function', 'communicative-instrumental function' and 8 subcategories were found. The most frequent function was the 'information delivery function' in the 'teaching-instrumental function' category. Implications for teacher education and further studies were discussed.

This paper examined the longitudinal changes observed in the emotional and instrumental values of children of primiparous mothers during the first to fourth year of childhood. Using latent growth modeling, the authors analyzed the four waves of data collected from 937 mothers and their firstborn babies nationwide in South Korea. This data was harvested from the Panel Study on Korean Children conducted by the Korea Institute of Child Care and Education. The results indicate that emotional and instrumental values of children showed decreasing patterns. When each year's parenting stress was controlled, the emotional value of children tended to increase, whereas the instrumental value of children showed no significant change. Generally, it was found that the higher the parenting stress of each year, the corresponding year's value of the children tended to be lower, except in the case of the first year's emotional value of children. How these results can be best interpreted as well as the implication of these results is also discussed.

This study investigates how dramatic increase of university and college graduates affects labor market outcomes. Using a series of seven repeated cross sections of the Vietnam Household Living Standards Surveys, this paper analyzed the changes in the rate of returns to higher education attainment along with the increased supply of university and college graduates due to the higher education expansion throughout the 2002-2014 period. The study utilized a ratio of number of university and college students to the number of upper-secondary pupils within each province as an instrumental variable to calculate the effects of higher education expansion on the labor wage. The study found that, with the basic equations, the coefficients for higher education attainment are statistically significant and have positive values for the whole period. Our instrumental variables were found to be valid. For instrumental variable estimation, the return to higher education in IV earning equations was quite high. The findings of this study suggested that the expansion of the higher education system in Vietnam during 2002-2014 had positive effects on wages for those who increased their education attainment due to the reforms and there was a declining trend of the returns to higher education toward the end of the period.

This study is an instrumental case study based on a theoretical proposition on animal phobia as a single case, Six categories were derived for the purpose of psychological analysis of the father of a female research participant suffering from the earthworm phobia. They are 'a fearful existence', 'problems with the woman who is always by her father's side', 'secret adultery and shock', 'fear of punishment', 'symbol for earthworm and fear displacement', and 'earthworm phobia'. Anxiety about punishment from a fearful father was the cause of the phobia. For the study participant, the earthworm phobia was the displacement of her father's fear of earthworm, and the earthworm phobia was interpreted as a substitute for her father. In other words, earthworm phobia should be understood as an escape and defense process as it replaces the re-emergence of long-repressed fearful feeling toward her father, and its symbolism can be seen as a metaphorical transformation of the pathological family atmosphere.

In this study, we explored the characteristics of instrumental genesis in high school students' scientific inquiries. Twenty-three 10th to 11th graders in a science research club participated in this study. The students in 6 groups autonomously planned and performed their own scientific inquiries for one semester. Their activities were videotaped and recorded. Semi-structured interviews were conducted. Material request papers and group worksheets were also collected for analysis. The results of the study suggested that students' practices were categorized as instrument genesis. When instrument genesis did not occur, the cases at the beginning of and during the practice were described respectively. Instrumental genesis was found to appear in three categories: instrumentation; instrumentation and instrumentalization; and instrumentalization. The characteristics and details of case represented in each category were described and discussed related to affordance as the results of the study. On the bases of the results, the implications for the reconsideration of the instruments in school science inquiries are discussed.

Purpose - The study was designed to explore and examine the business relationships of the owners and the employees of Market Basket to analyze the implications of their recent turbulence and decisions. This article focused on two issues - business profit and labor union - to describe the uniqueness of this case. Design, methodology, data, and approach - This article, based on its purpose, applied all three approaches of case studies that are identified and described by Stake (1995), instrumental, intrinsic, and collective, to present the core nature of the issue and to improve and gain a clear understanding of this particular phenomenon. Results - The analysis of this case clearly indicates that seemingly dichotomous concepts of profit and employee welfare are not necessarily antithetical to each other Conclusions - The instant case of Market Basket serves as a testimonial for the rejection of the basic premises of corporate profits and labor unions. This case serves as a model and a practical example for many large retailers, especially the family operated retailers, and workers throughout the world.
