  • The purpose of this study was to study the Relationships between Sport for All Participation and Physical and Mental Function affecting the Elderly's Self-perceived Health. For accomplishing this purpose of this study, the 308 subjects were selected by the multi-stage stratified cluster sampling method from the Seoul, in the years of 2008. presently. Out of the 360 questionnaires responded to, only 308 were used for data analysis because 52 were responded to incompletely or incorrectly. The survey questionaries were used to collect data. The questionary for physical function state were developed and standardized by kung-hee chung(1993), yang-lae Kim(2005). And mental function state were divided two parts; self-perceived scale and depress scale. The questionary for self-perceived scale were based on MMSE-K(Mini Mental State Examination-Korea). The questionary for Depression were based on Depression Scale developed by Beck(1978), adapted in Korean and standardization by Lee Young-ho & Song Jong-yong(1991), regulated by Jo Gyu-whang(2004). From the analysis of this study, the following conclusions were obtained: First, according to the elderly people's participation in leisure sport activities, it partially affected physical and mental function state. Second, according to the degree of elderly people's participation in leisure sport activities, it partially affected physical and mental function state.

  • Objectives : Based on a national sample survey, we present an analysis of the current situation in the use of moxibustion therapeutics by qualified medical practitioners in Korea. Methods : The survey population of 11,737 hospitals is stratified by administrative regions, and 331 of them are randomly selected from the list of hospitals. The same number of Korean medical doctors is interviewed under the computer-assisted telephone interviewing(CATI) system. The bound on the error of estimation is ${\pm}\;5.0%$ point. Results : Of the 331 Korean medical doctors surveyed, 69% have used moxibustion therapy for remedial treatment. About half of those doctors have employed the therapy for their patients over 30%. The average number of acupuncture points per treatment using the therapy mostly ranges 1 between 5. The percent of practitioners, who have the number of average minutes less than 20 in treatment, is 74%. The number of practitioners who primarily use modified moxibustion is 4 times as many as that of those using traditional moxibustion. Conclusions : Considering the survey results, if the laser heater, alternative to conventional moxibustion, which not only gives high thermal effect but also reduces both the users inconvenience and side effects, are developed, it may benefit more patients as well as Korean medical doctors.

  • We present a mixed multiplicative quantitative randomized response model which added a unrelated quantitative attribute and forced answer to the multiplicative model suggested by Bar-Lev et al. (2004). We also try to set up theoretical grounds for estimating sensitive quantitative attribute according to circumstances whether or not the information for unrelated quantitative attribute is known. We also extend it into the stratified mixed multiplicative quantitative randomized response model for stratified population along with two allocation methods, proportional and optimum allocation. We can see that the various quantitative randomized response models such as Eichhorn-Hayre's model (1983), Bar-Lev et al.'s model (2004), Gjestvang-Singh's model (2007) and Lee's model (2016a), are one of the special occasions of the suggested model. Finally, We compare the efficiency of our suggested model with Bar-Lev et al.'s (2004) and see that the bigger the value of $C_z$, the more the efficiency of the suggested model is obtained.

  • Purpose: The purpose was to determine the content validity of a semantic revision of items on a reliable and valid instrument, the Sieloff-King Assessment of Group Outcome Attainment (Power) within Organizations in Korea (K-SKAGOAO). Methods: The target population for research was chief nurse officers (CNOs) of all hospital within Korea. A sample of 303 hospitals from across the Korea was selected through a stratified random sampling process. A total of 174 CNOs comprised the final sample. Psychometric evaluation of the K-SKAGOAO included: (a) criterion-related validity (b) factor analysis and (c) internal consistency reliability using Cronbach's alpha coefficients. Results: The Convergent validity and criterion-related validity were supported. Cronbach's alpha coefficient for the K-SKAGOAO was .95. Subscale alphas ranged from .60 to .86. Conclusion: The K-SKAGOAO and related subscales show validity and internal reliability. A nursing group of any size can use the K-SKAGOAO to both assess the group's level of outcome attainment and develop strategies to further improve that level.

Method: Data were collected through questionnaire surveys. Internal consistencies for this questionnaire ranged from 0.63 to 0.88. The subject used in this study consisted of 922(delinquent : 367, student : 555), using the proportional stratified random sampling method. Statistical methods employed were Chi-square and t-test. Results: \circled1 The rate of suicidal attempts were 10.8%, and the highest peak age of suicidal attempt was 17-18 year old (16.9%). \circled2 Delinquents(19.6%) showed a higher rate of suicidal attempts than students (5.1%). Among the students, girls (43.3%) showed a higher rate of suicidal attempt than boys (19.1%). Whereas, boys (80.9%) showed a higher rate of suicidal attempt than girls (56.7%) among delinquents. \circled3 Those who attempt suicide have more familial problem such as incest, psychosis, depression, attempted suicide, committed suicide, and alcoholism in their family. They also have more dysfunctional family dynamics, environment, and maladaptive personalities than non-attempters. Conclusions: Suicide and suicidal behaviors are multifaceted events. For suicide prevention, independent assessments of variables such as familial problems, personality, family dynamics, and environment must be considered.

  • Objective: This study was an attempt to identify associations between health behavior, such as smoking, alcohol consumption, healthy diet, and physical activity, and psychosocial factors. Methods: This crosssectional study was conducted among 1,500 participants aged between 30 and 69 years, selected from a population-based database in October 2009 through multiple-stratified random sampling. Information was collected about the participants' smoking and drinking habits, dietary behavior, level of physical activity, stress, coping strategies, impulsiveness, personality, social support, sense of coherence, self-efficacy, health communication, and sociodemographics. Results: Agreeableness, as a personality trait, was negatively associated with smoking and a healthy diet, while extraversion was positively associated with drinking. The tendency to consume a healthy diet decreased in individuals with perceived higher stress, whereas it increased in individuals who had access to greater social support. Self-efficacy was found to be a strong predictor of all health behaviors. Provider-patient communication and physical environment were important factors in promoting positive healthy behavior, such as consumption of a healthy diet and taking regular exercise. Conclusions: Psychosocial factors influence individuals' smoking and drinking habits, dietary intake, and exercise patterns.
