  • Objectives: The purpose of the study is to investigate the relationship between the number of remaining teeth and bone health status among adults over 65 years old. Methods: The study subjects were 1,843 adults over 65 years old drawn from the Korea National Health and Nutrition Examination Survey (KNHANES) in 2008-2010. Oral health status included the number of remaining teeth, and prosthetic appliance status. Bone health statuses were assessed using dual-energy X-ray absorptiometry (DEXA). Bone health statuses were classified into normal (T-score ${\geq}-1.0$), osteopenia (-2.5 < T-score < -1.0), and osteoporosis (T-score ${\leq}-2.5$). Complex samples chi-square test was used to estimate the relationship between the number of remaining teeth and bone health status, and related factors included in the model were analyzed with the complex samples logistic regression analysis. Results: Using the multinomial logistic regression analytic method, the elderly having 20 or more remaining teeth and those having less than 20 remaining teeth with prosthesis were compared. The latter group had 1.89 times higher rate of being diagnosed as having osteoporosis. Conclusions: This study suggests that oral health is an important factor for geriatric osteoporosis. Therefore, in order to prevent fractures due to osteoporosis and osteoporosis in old age, it is necessary to be aware of the relationship between oral health and osteoporosis, and oral health should be considered when preparing preventive management strategies.

  • Objective : The aim of this study was to investigate the individual and job related factors as risk factors for mental health of firefighters. Methods : The data of 202 fire-fighters was analyzed by using a multinomial logistic regression analysis. All participants completed self-reported questionnaires including demographics (sex, age, work duration), the Childhood Trauma Questionnaire, the Ways of Coping Checklist, the Colleague related traumatic events, the Korean occupational stress scale, the Korean Perceived Stress Scale-10, and the Beck Depression Inventory. Participants were divided into three groups according to the level of stress and depressive symptom scores: Low Stress-Low Depression (LS-LD), High Stress-Low Depression (HS-LD), and High Stress-High Depression (HS-HD). Results : A job related factor-organizational injustice-was a significant factor related to HS-LD, while individual factors such as active coping level and childhood trauma experience and a job related factor-difficult physical environment-were significantly associated with HS-HD. Conclusion : These results imply the need to take both individual and environmental approaches into account when managing the stress and depression of firefighters. More specifically, psycho-education to facilitate active coping strategy and adaptive emotional regulation at the individual level and the improvement of physical work environment of firefighters should be supported.

  • The purpose of this study is to segment and examine urban farmers behavior by applying a two-step cluster analysis and multi-nominal logit model. The data were collected by a telephone survey with two-staged stratified random sampling in the cities around the country for the purpose of acquiring representative data. Respondents were asked to describe their awareness of urban agriculture, their agricultural activity, and sociodemographic characteristics. Among 2,000 cases, 381 cases(19.1%) which were of participants in urban agriculture were analysed in SPSS. From the findings, 27.3% of respondents had heard the word 'urban agriculture', and 25.5% of them regarded themselves as urban farmers. Four different clusters were derived from two-step clusters based on motive, place, companion, area and hours. They were 'Large scale hobby farming(cluster 1)', ‘Weekend farm/ hobby farming(cluster 2)', 'Land/ Self-supporting farming(cluster 3)', and 'Small scale hobby farming(cluster 4)'. The result of multinomial logistic regression showed that there were significant differences among these four segmented groups in terms of age, city size and housing type. In other words, there is quite a possibility that urbanites select different urban farming types according to their socio-demographic profiles. Therefore, the urbanite profiles can be used as the basis for promoting policy of several urban agriculture types. According to the result, policy directions for facilitating urban agriculture were presented.

  • Objectives : This study aimed to investigate the types of unmet health care needs of the elderly and factors affecting them. Methods : This study used data from the 2012 Community Health Survey. Multinomial logistic regression analysis was conducted to identify the relevance between each type of unmet health care needs and predisposing, enabling, and needs factors, based on the cases without unmet health care needs. Results : Persons with unmet health care needs were 4,460 (9.5%) of the total sample. By types of unmet health care needs, 1,171 (2.5%), 1,026 (2.2%), and 2,263 (4.8%) persons reported inaccessibility, non-accommodativeness, and unaffordability respectively. It was concluded that the there were differences in the associated factors according to the types of unmet medical needs. Conclusions : It is suggested that unmet health care needs in the elderly should be examined from diverse angles rather than from a single aspect of partial limits. In particular, diverse types of unmet health care needs for health care in the elderly according to limited accommodation shoulder be examined. Finally, strategies to decrease unmet health care needs that reflect the associated factors should be developed.

  • The purpose of this study was to evaluate the relationship between early menopause and periodontal disease in postmenopausal women using data from the 6th Korean National Health and Nutrition Examination Survey (2013~2015). A study was conducted with 2,048 postmenopausal women aged 45 to 74 years. Participants were divided into the early menopause group (menopause occurring at age 45 years or before) and normal menopause group (menopause occurring after age 45 years). A community periodontal index greater than or equal to code 3 was used to define periodontal treatment needs. A chi-square test was used to confirm the bivariate relationship between the variables. Multinomial logistic regression analysis was used to adjust for covariates (age, education, family income, body mass index, alcohol drinking, smoking, visiting dentist in the last year, use of oral care products, frequency of tooth brushing per day). The risk of periodontal disease was higher in the early menopause group after adjusting for potential confounders (odds ratio, 1.59). In particular, the relationship between early menopause and periodontal disease was more evident in women with low education and those who did not use oral care products. The findings of this study suggest that early menopause is a significant factor of periodontal disease in Korean women.

  • This study aims to identify the decision-making factors of people who have returned to rural areas for farming and residence according to personal characteristics and regions. The survey was conducted on 420 return farmers of six cities and counties in Gyeongsangbuk-Do from September 1st to October 11th 2013. For data analysis, researchers used 280 answered sheets and utilized two-way ANOVA and multinomial logistic regression analysis. Research results indicate three factors of returning to farm which are pull to rural area, push from city, and policy factor. The highest scores of factor is pull to rural area (2.93), the second one is push from city (2.31), and the lowest score is politic factor (2.18). In addition, these three factors of returning to farm are elucidated by environmental variable, economic variable, and information and opportunity provided by government. In other words, the factor of pull to rural area is related environmental variable and the factor of push from city is affected by economic variable. Lastly, politic factor pertains to information and opportunity provided by government.

  • Purpose: The number of Korean adolescents engaging in gambling is increasing, especially among out-of-school adolescents. This study aimed to identify patterns of gambling activities and factors related to specific subgroups of out-of-school adolescent gambling activities. Methods: This descriptive study analyzed secondary data from the 2015 Korea Youth Gambling Problem Survey, including 1,200 out-of-school adolescents. Latent class analysis was conducted to identify patterns of gambling activities. The factors related to gambling subgroups were verified with multinomial logistic regression. Results: Three latent classes of gambling activities were identified: rarely gambling (RG), immediate gain gambling (IGG), and broad gambling (BG). These subgroups differed significantly in terms of gender, age at and type of first gambling experience, number and type of gambling activities, gambling frequency, time and money spent on gambling, problem gambling severity, and motivation for gambling. Compared to the RG subgroup, both the IGG and BG subgroups were strongly associated with an older age at the first gambling experience. Conclusion: Out-of-school adolescents who first gambled at an older age and who gambled mainly in order to gain money immediately were at risk of problem gambling. Developing strategies for early screening and referral to professionals is necessary to prevent gambling problems from worsening.

  • 이 연구는 1996년 "아시아 사람들의 직장 생활에 관한 조사" 자료를 이용하여 한국의 취업시장에서 사회 연결망 활용에 영향을 미치는 요인을 분석하였다. 취업자를 하위 범주로 나누지 않고 보았을 때는, 사회 연결망이 공식 경로와 직접 접촉보다 더 중요한 취업방법임을 알 수 있다. 다항 로짓 분석 결과는 대체로 취업시장에서 유리한 위치에 있는 취업자 범주가 사회 연결망을 덜 활용한다는 점을 보여준다. 이것은 한국의 취업시장이 여러 가지 기준에 따라 뚜렷하게 나뉘어 있으며, 더 나은 사회 경제적 보상을 가져다 주는 취업시장에서는 공식 경로를 통한 경쟁이 주된 취업방법이라는 한국의 취업시장의 특징을 보여준다.

  • Purpose: This study was conducted to characterize the influence of achievement motivation and the parent-child relationship on ego identity in Korean nursing students. Methods: The participants were 217 Korean nursing students in the first and fourth year of university. Data were collected through self-report questionnaires composed of items assessing ego identity, achievement motivation, the parent-child relationship, and demographic characteristics. The data were analyzed using descriptive statistics, one-way analysis of variance, the $x^2$ test, and multinomial logistic regression analysis. Results: Ego identity was related to achievement motivation; moreover, the achievement motivation of students with moratorium and achieved identity status was significantly higher than that of students with low-profile moratorium and diffused identity statuses. Ego identity was not related to the mother-child relationship, but the father-child relationship of students in foreclosure was significantly higher than that of students with diffused identity status. The factors influencing achieved identity compared to diffused identity were achievement motivation, year in school, satisfaction with school, and having religious beliefs. Conclusion: These findings indicate that nursing students' ego identity attainment was more influenced by achievement motivation than by the parent-child relationship. It emphasizes that highly motivated students can develop their own identities regardless of the parent-child relationship.
