Thanks to information technologies, sharing economy services offer a new way of consumption. Carsharing appeared as a novel type of service that transformed the conventional way of personal transportation, from owning a vehicle to using an on-demand service. Allowing users to use a vehicle without owning a car, carsharing provides various social benefits such as the reduction of resource allocation inefficiencies and the alleviation of transportation problems. To strengthen such positive aspects of carsharing service, it is essential to understand an individual's service usage pattern and reveal factors that affect users' reuse behavior. This study investigates the factors that have an influence on carsharing reuse of users applying RFMC (Recency, Frequency, Monetary, and Clumpiness) model, the popular model for understanding the reuse likelihood of customers. Using data from a leading carsharing service provider in South Korea, we empirically analyze the effect of RFMC on carsharing reuse behavior. The findings show that recency and monetary values are negatively related to reuse while frequency is positively related to carsharing service reuse. Moreover, the impact of recency and monetary value are more salient whereas the impact of frequency is smaller among users with higher clumpiness. Based on these findings, this study elaborates on theoretical and practical implications.

The purpose of this study is to understand the adjustment process of families adopting an older child, and to generate a substantial theory. To achieve this purpose, we conducted in-depth interviews with mothers adopting an older child and analyzed data with qualitative analysis approach. From the analysis, theoretical model has been made, and the model includes the adoptive families' diverse experiences, barriers to adjustment as well as resources and strategies that they mobilized and used for smooth adjustment. Their experiences in the process of adjustment consisted of five phases: unfamiliar meeting, shock, fighting alone without support, control, and stability. Barriers to adjustment process were composed of adoptees' problem behaviors, loss of time, lack of preparation, lack of experiences, repetition of the vicious circle, withstanding alone, improper resources, lack of support, and being criticized. Resources and strategies that families adopting an older child utilized were individual resources and ability such as rearing experiences, intellectual ability, willingness, belief, and perspective change; family system such as spouse and other offsprings; informal support system such as extended families, relatives, friends, neighbors, and other families adopting an older child; formal resources such as adoption workers and helping professionals. From our results, we suggested policy and practice guidelines to help adjustment experiences for families adopting an older child.

Housewives' perception on obesity related variables to their family members according to the composition of children in the family was explored. Ninety housewives responded to a questionnaire consisted of sociodemographic informations, body weight perception, eating behaviors perception, and physical activity level for herself as well as her family. They were categorized into three groups based on child composition of the family; boys only (BO), girls only (GO), and boys and girls (BG) families. Boys in BO showed higher value of height, weight, and WHR than girls in GO (p <.05), while no differences were noticed in BMI and the waist girth between the groups. Mothers of BO perceived boys were active while mother of GO did girls were inactive (p <.05). Girls in GO ate meals less regularly than boys in BO and girls in BG. In general, housewives' perception on body weight of family members was relied on BMI and waist girth. As mother's BMI increased, the boy's BMI in BO was also elevated (p <.05), but not in others. Mothers' perception on caloric intake and activity encouragement were not accounted for morphological characteristics. Results suggest that housewives perceived obesity related variables differently based on the composition of children of the family.

Self efficacy is a term used in psychology, roughly corresponding to a person's belief in their own competence. It has been defined as the belief that one is capable of performing in a certain manner to attain certain goals. It is believed that our personalized ideas of self-efficacy affect our social interactions in almost every way. Understanding how to foster the development of self-efficacy is a vitally important goal for positive psychology because it can lead to living a more productive and happy life. The objective of this study is to show difference of the relationship between user and non-user in smartphone by self efficacy. For this purpose, we propose a research model which consists of 3type' self efficacy. For empirical test of this model, the sample data is collected from employee in a company and divided into two groups by user and nonuser. By multi-group analysis, we show two groups are different from each other in the relationship between user and nonuser of smartphone. Results show difference of the relationship smartphone user and non-user's self-efficacy(self-control self-efficiacy and problem difficulty preference).

The Korean society has been dramatically changed in its population, with rapidly increasing number of multicultural families through international marriages. The objective is to investigate the dietary patterns as an acculturation for multicultural families in urban area. The research target was 89 marriage immigrant females in Daejeon, in whom 50.6 % was in their twenties and 49.4 % was in their thirties to forties. 39.3% of the subjects was from China and 28.1 % from Vietnam, which showed similar pattern to the ratio of marriage immigrants' homeland in Korea. As age goes higher, cultural adaptation in Korea was the integration pattern. Marriage immigrant females from Vietnam showed the highest rates of marginalization pattern as cultural adaptation. Moreover, those with longer marriage duration and with children tend to show higher rates of integration pattern. 'Food attitude', 'food diversity', and 'balance life' as eating behaviors are related with acculturation. In conclusion, the multicultural families in urban area showed integration acculturation patterns, which could be influenced by their socioeconomic factors, such as residence period and Korean language ability and food diversity as dietary patterns factors. Further study with a quantitative analysis is needed in order to understand the effect of dietary patterns on acculturation in the multicultural families.

It is crucial to process not only social cognitive information but also various emotional information for appropriate social interaction in everyday life. The processing of emotions embedded in social stimuli is affected by various context and external factors and the features of their own. Emotion discrimination tasks using point-light biological motion were conducted in this study to understand the factors influencing emotion processing and their effects. A target biological motion with angry or happy emotion was presented in the first task in red, green, white, or yellow color. A white angry, happy, or neutral "cue" biological motion was displayed simultaneously. Participants judged the emotion of the target relative to the cue stimulus by comparing the target with the cue. The second task used only emotionally neutral stimuli to find effect by the color itself. The results indicated an association between the specific color of the target and emotion. Red facilitated processing anger, whereas green appeared to facilitate happy emotion. The discrimination accuracy was high when the emotions of the cue and the target were identical in general, but the combination of red color and anger yielded different results compared with the rest of the conditions. Some illusory emotional responses associated with the target colors were observed in the second task. We could observe the effects of external factors in this study, affecting the emotional processing using biological motion rather than conventional face stimuli. Possible follow-up studies and clinical research were discussed.

This study was designed to investigate and evaluate the dietary intake of 30 housewives, aged 35 to 59. The subjects kept daily diet records lot a period of one year. Their mean daily nutrient intakes met or exceeded the RDA (recommended dietary allowance) for all categories except energy, calcium, iron, vitamin A, and vitamin B$_2$. Mean daily calorie intakes were 81.2% of the RDA. The subjects received about 19% of their energy from fat and 15% from protein. Nutrient adequacy ratios (NAR) were 0.60 for calcium, 0.62 for iron, 0.71 for vitamin A, and 0.76 for vitamin B$_2$. The mean adequacy ratio (MAR) was 0.79. Subjects received various nutrients from rice, pork, eggs, and Kimchi. Rice was a major contribute. to many subjects' nutrient intake due to the high amount of consumption. Pork, rice, and vegetable oil greatly contributed to fat intakes while eggs, pork, and beef supplied a high level of cholesterol compared to other foods. Kimchi, anchovies, and milk were the major contributors of calcium, while rice, pork, and Kimchi were the major contributors of iron. These results indicate that the major nutritional problem of middle-aged housewives is an overall inadequate intake of energy, calcium, and iron.
