  • 본 논문에서는 경영학 재무 분야에서 국내외적으로 지속적인 관심의 대상이지만, 학문적 의견 일치를 보이지 못하고 있는 주제가 연구되었다. 즉, 기업의 수익성에 대한 재무적 결정요인과 상호 차별성이 가설검정을 통하여 상호 비교되었다. 연구 분석 방법과 관련하여 본 연구에서는 국내 재벌 계열사들을 대상으로 표본기간은 국제금융위기 이후의 기간으로 설정되었으며 시장가치와 장부가치 기준의 두 분류의 수익성 지표들이 각각 분석되었다. 첫 번째 가설검정 결과 관련, 총 7개의 설명변수들 중, 기업 규모와 부채비율을 제외한 나머지 변수들이 재벌기업들의 수익성 결정에 유의성 있는 영향을 줄 수 있는 재무적 요인들이었으며, 동 결과는 비교그룹인 비재벌 소속 기업들에 대한 검정 결과와도 일반적으로 유사하였다. 또한, 다항로지스틱 모형을 활용한 두 번째 가설 검정에서는, 표본기업인 재벌기업들이 수익성 수준을 기준으로 3단계로 분류되었다. 이를 기준으로 부채비율, 부도위험성 그리고 잠재성장성을 나타내는 변수들이 재벌기업들 간의 차별성을 나타내는 변수들로서 판명되었다. 본 연구의 결과들은 국제금융위기라는 재무적 시점을 경험한 국내 재벌기업들의 수익성 결정요인들을 판명하는 측면에 새로운 방향을 제시할 수 있다고 판단하며, 또한 선순환적 관점에서 정부와 기업을 포함한 이해관계자들의 향후 이익 제고에도 기여할 수 있다고 판단된다.

  • 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.

  • 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.

  • Purpose: This study was conducted in order to identify factors that influence depression for low-income elderly who live at home from the International Classification of Functioning model (ICF). Methods: The subjects were 205 elderly people living at home in two public health centers located in metropolitan cities. Subjects were divided according to their depression scores, which were measured using the GDS-short form, including normal, risk, and depression groups. Each variable was consistent with factors of the ICF model, including health condition, individual factors, environmental factors, body function, activities, and participation. Data were collected using structured questionnaires. ANOVA, $x^2$, Pearson's correlation coefficient, and Multinomial logistic regression with IBM SPSS 21.0 were used for analysis of the data. Results: Statistically significant differences were observed among normal, risk, and depression groups regarding personal factors. Gender, education level, numbers of diseases, perceived health, life satisfaction, and social support were identified as the variables that had a significant impact on depression of low-income elderly living at home. Conclusion: Results of this study indicate that there is a need for construction and implementation of strategies that strengthen life satisfaction and social support in order to lower depression of low-income elderly.

  • Objectives: This study was conducted to examine the association between health condition and leaving the labor market among middle-aged and older adults in South Korea. Methods: Data was obtained from individuals aged 45 years and older participating in the 2006 and 2008 Korean Longitudinal Study of Ageing. We used various health measures including chronic diseases, comorbidities, traffic accident injuries, disabilit of instrumental activities of daily living, depressive symptoms, and self-rated health. The odds ratios of job loss, and retirement, versus employment were calculated using multinomial logistic regression by each health measure. Results: In our cross-sectional and longitudinal analysis, health problems related to physical disabilities had the greatest effect on leaving the worksite. A shift in health condition from good to poor in a short period was a predictor of increased risk of unemployment but a persistent pattern of health problems was not associated with unemployment. Women with health problems showed a high probability of retirement, whereas among men, health problems instantly the possibility of both job loss and retirement. Conclusions: Health problems of middle aged and older workers were crucial risk factors for retirement and involuntarily job loss. Especially functional defect and recent health problems strongly and instanty affected employment status.

  • Purpose: This secondary data analysis study was aimed at identifying the factors related to the patterns of alcohol use (normal alcohol use, hazardous alcohol use, and alcohol dependence) in the Korean adult. Methods: This study analyzed the cross-sectional data from 230,715 Korean adults aged 19 year and older who participated in the 2009 Korean Community Health Survey. Multinomial logistic regression was used to uncover associations between demographic, health related factors and the patterns of alcohol use. Results: The patterns of alcohol use was differentiated from the sociodemographic variables (residential area, gender, age, marital status, educational level, monthly income, and occupation) and with health related factors (smoking status, hours of sleep, body mass index, pain or discomfort, subjective health, stress level, liver disease, cardio/cerebro vascular disease, and depression). Hazardous alcohol use was lower in rural areas and lower among women, but higher among people who smoke, reported severe stress, and/or depression. Similarly, alcohol dependence was lower among women and among those in rural areas, and was more likely associated with those who smoke, have severe stress and depression. Conclusion: A number of factors are associated with patterns of drinking. Smoking, severe stress and depression seems to confound the problems of alcohol use. Additional research is needed to isolate those factors that are the most important influencing the use of alcohol.
