As game players have been more diverse and new features of digital games have been emerged in recent days, it is important to find out and understand how recent game players recognize and classify digital games. Thirty game players conducted Q-analysis of twenty-nine Q-statements extracted from previous studies on game typology. By using a QUANL program, three different types were revealed. For game classification, 'Physical Environment Centric Players' type highly values external game elements from the outside perspectives. 'Contents Centric Players' type considers internal game elements as the most important criterion. 'Emotional Experience Centric Players' type values his/her subjective feeling and thoughts. Based on this study, it is expected to make a contribution in developing a framework of game players with their perspectives on game classification.

The rapid development of information and communication technology has made it for people to pirate digital contents easily and quickly. Although many studies have investigated the underlying factors that lead to an individual engaging in digital piracy, few studies have provided holistic and integrative view on this issue. Therefore, this study attempts to build integrative research model based on theory of planned behavior (TPB), norm activation model (NAM), and habit. For this purpose, this study develops nine hypotheses that explain the relationship between attitude, personal norm, habit, and behavioral intention, and tests them with survey data collected from 337 participants. The results of this study show that attitude, perceived behavioral control, personal norm, and habit have impact on behavioral intention of digital piracy while subjective norm does not affect behavioral intention. This study contributes to expand existing studies by identifying the relationship between attitude, personal norm, habit and behavioral intention.

Along with the aging society, the prevalence of dementia is also increasing. Dementia causes short-term memory loss as well as difficulties of performing daily activities and gradually causes suffering of the patients and their family. In spite of various programs for prevention of dementia of older people are being implemented, there is a lack of developing natural-based program for physical and mental health promotion. Therefore, it is necessary to develop programs for the elderly living alone who are more vulnerable to dementia because of their social and economic isolation. The purpose of this study was to develop a natural-based program and investigate the effects of 10 weeks forest therapy program for dementia prevention to improve the psychological and physical health of the elderly living alone. The experimental subjects were 30 elderly (aged 65 or older) and 31 elderly participated in control group. The Stress response, depressive symptoms, weight, body mass index (BMI), fat mass and muscle mass were measured for pre and post test. The results showed that the experimental group showed subjective stress relief (t=5.249, p=.000), improvement in symptoms of depression (t=4.152, p=.000), and decreases in weight (t=2.686, p=.012), BMI (t=2.629, p=.014) and fat mass (t=2.918, p=.007) after the forest therapy program. The experimental group showed lower stress reactions(t=-7.185, p=.000) and less depressive symptoms (t=-5.303, p=.000) than control group after participating the program. These results suggest that periodic forest exposure can help having less stressful and depressive status than non-forest exposure and the forest therapy program can reduce participants' psychological and physical risk factors of dementia.

Purpose Virtual communities (VCs) are becoming ever more important in these days, sometimes more than offline communities. Notably, they have become significant sources of knowledge sharing. Therefore, in order to foster a VC, it is very important to understand why people share their knowledge in the VC. Under this background, this paper aims at proposing the behavioral model best explains knowledge sharing activities in VCs. Design/methodology/approach We basically design our behavioral model for knowledge sharing in VCs based on theory of reasoned action (TRA). However, to understand knowledge sharing in VCs better, we specify knowledge sharing by dividing it into knowledge contribution and knowledge use. Also, instead of 'subjective norm', we adopt 'sense of virtual community (SOVC)' as a main social factor, which has been found to be important in the literature. We also include the antecedents such as 'quality of the shared knowledge', 'trust in community members', 'passion of the community leader', 'reciprocity', and 'self efficacy', which affect VC users' attitude towards knowledge sharing and SOVC. To test the hypotheses in our proposed model, we collected 253 valid surveys from the VC users. Structural equation modeling (SEM) using AMOS 23 is employed to assess the relationships proposed as the hypotheses. Findings Major findings are as follows. SOVC positively affects both intention to contribute knowledge and intention to use knowledge. And, trust in community members positively affects the attitude towards knowledge use and SOVC. The attitude towards knowledge use is also affected by the quality of the shared knowledge. Reciprocity is found to strongly positively affect the attitude towards knowledge contribution. However, passion of the community leader and self efficacy are found to have insignificant effect on SOVC and the attitude towards knowledge contribution respectively. Our study sheds a light on how to foster VCs from the perspective of knowledge management.

Objectives: This study examined the characteristics and nutritional risk of the elderly who receive home delivery services. We then analyzed the effects of the characteristics of the elderly who receive the home-delivery meal service on their nutritional risk. Methods: A total of 220 respondents who receive home-delivery meal service in Seoul participated in the survey. The survey consisted of the characteristics of the elderly (health status, tooth condition, physical activity, social participation activity, depression and relationship with neighbors), nutritional risk assessment and other general matters. The data was analyzed by using the SPSS program. Cross-tabulation analysis, t-test, correlation analysis and regression analysis were all conducted. Results: 47.0% of the subjects were under 80 years old and 53.0% were over 80 years old, The nutritional risk score, as evaluated by a Nutrition Screening Initiative (NSI) checklist was 10.7 points, and the high nutrition risk group was 91.5% of the subjects. The subjective self-health status score was 2.24 points (out of a total of 5 points) and the tooth status score was 3.30 points. The physical activity level was 2.17 points for the under 80 years old group and 1.76 points for the over 80 years old, and there was a significant difference according to age (p<0.01), The higher the health status, tooth condition, physical activity and social participation activity level, the lower was the nutritional risk. Further, the higher the degree of depression, the higher was the nutritional risk. Conclusions: For the healthy life of the elderly in the community, various welfare policies should be planned to increase social participation as well as to promote physical health and reduce depression.

This study is a descriptive research study for examining the general characteristics and health-related characteristics of the elderly in a local community, investigating factors for the fear of fall and identifying the relationship between the fear of fall, attitude to fall and fall efficacy. The subject of this study was 140 senior citizens who are using a community center in D city. The collected data was analyzed with the SPSS/WIN 21.0 program. The result of the study showed there was a significant difference in the fear of fall according to gender, person living together, subjective health condition, pain and unsafe gait. There was a significant negative correlation between the fear of fall and fall fear and fall efficacy. However, fall fear and fall efficacy were positive correlated. This study aims to provide necessary preliminary data for developing fall prevention program that can improve the fear of fall, attitude to fall and fall efficay based on the results of this study.

This study conducted a survey from September 5 to 30, 2020 targeting 415 workers participating in regional self-sufficiency center programs in four locations in Daejeon and Daegu. The purpose of the study was to examine oral symptoms of the study subjects and the effects if psychological anxiety parameters on oral health and quality of life. As a result of the study, oral dryness, temporomandibular joint symptoms, and periodontitis all had a significant effect on oral health and quality of life, and psychological anxiety factors had a partial mediating effect. The subjective oral symptom problems led to a negative psychological state, which could further impair the quality of life. In the future, the results of this study can be used as basic data for expanding psychological counseling programs for self-supporting workers and improving oral health policies for regular oral health education.

Objectives: We aimed to find the relationships between employment status and hs-CRP level among Korean wage workers using the 2016 Korean National Health and Nutrition Examination (KNHANE, revised). Methods: This study was conducted on 1,937 daytime wage workers over the age of 19 and within a normal weight range (18.5≤BMI≺25). Regular workers were defined as those granted an employment guarantee until reaching retirement age, and non-regular workers were defined as temporary, non-typical, dispatched, short-term workers and contractors. For hs-CRP, three divisions were classified as recommended by the Centers for Disease Control and Prevention (CDC) and American Heart Association (AHA) with less than 1.0 mg/L indicating low risk of cardiovascular disease, above 1.0 mg/L and below 3.0 mg/L considered moderate risk, and more than 3.0 mg/L indicating high risk. To find the relationship between work type and hs-CRP level in Korean wage workers, multinominal logistic regression analysis was performed. Results: For non-regular workers, the odds ratio of the cardiovascular moderate-risk group and cardiovascular high-risk group was statistically significant compared to regular workers. After adjusting for factors such as gender, age, subjective health status, income, education, smoking, and physical labor, the odds ratio of the cardiovascular high-risk group was statistically significant. Conclusions: In this study, the relationship between non-regular workers and high hs-CRP level was examined. Based on this, institutional strategies should be pursued to prevent and manage cardiovascular disease among non-regular workers.

Intestinal obstruction diagnosis method based on X-ray can affect objective diagnosis because it includes subjective factors of the examiner. Therefore, in this paper, a detection method of Intestinal Obstruction from X-Ray image using Hough transform and PCM is proposed. The proposed method uses Hough transform to detect straight lines from the extracted ROI of the intestinal obstruction X-Ray image and bowel obstruction is extracted by using air fluid level's morphological characteristic detected by the straight lines. Then, ROI is quantized by applying PCM clustering algorithm to the extracted ROI. From the quantized ROI, cluster group that includes bowel obstruction's characteristic is selected and small bowel regions are extracted by using object search from the selected cluster group. The proposed method of using PCM is applied to 30 X-Ray images of intestinal obstruction patients and setting the initial cluster number of PCM to 4 showed excellent performance in detection and the TPR was 81.47%.

Objectives: We examined which socioeconomic and intergenerational characteristics were associated with the level of intention to marry among Korean men and women in young adulthood. Method: Data came from 351 men and 391 women who were 25-34 years old, had never been married, and had at least one living parent. We conducted multiple regression analyses by gender after controlling for age and current romantic relationship. Results: Among the socioeconomic characteristics, more years of education was linked to both men's and women's higher levels of intention to marry. For women, having a secure, full-time job was related to greater intention to marry. For men, the higher their subjective socioeconomic status, the greater their intention to marry. Among intergenerational characteristics, both men's and women's positive attitudes toward supporting elderly parents were related to a higher level of intention to marry. For men, the frequency of providing instrumental support for their parents was negatively associated with the men's intention to marry. For women, higher levels of agreement with parents' responsibility to support their adult children as well as greater affection for their parents were positively related to greater intention to marry. Conclusions: The findings suggest that young adults' socioeconomic resources and the family context are important predictors of young adults' marital intentions. The results also reveal gender differences in the factors associated with young adults' marital intentions.
