  • The Household Income and Expenditure Survey is a representative survey of Statistics Korea, which aims to measure and analyze national income and consumption levels and their changes by understanding the current state of household balances. Recently, the disconnection problem in these time series caused by the large-scale reorganization of the survey methods in 2017 and 2019 has become an issue. In this study, we model the characteristics of the time series in the Household Income and Expenditure Survey up to 2016, and use the modeling to compute forecasts for linking the expenditures in 2017 and 2018. In order to evenly reflect the characteristics across all expenditure item series and to reduce the impact of a specific forecast model, we synthesize a total of 8 models such as regression models, time series models, and machine learning techniques. In particular, the noteworthy aspect of this study is that it improves the forecast by using the optimal combination technique that can exactly reflect the hierarchical structure of the Household Income and Expenditure Survey without loss of information as in the top-down or bottom-up methods. As a result of applying the proposed method to forecast expenditure series from 2017 to 2019, it contributed to the recovery of time series linkage and improved the forecast. In addition, it was confirmed that the hierarchical time series forecasts by the optimal combination method make linkage results closer to the actual survey series.

  • This study examined the relationship between physical education and externalizing(aggression) and internalizing(depression, social withdrawal) problem behaviors among adolescents. The moderating role of gender and time in the association between physical education and problem behavior was also identified. This study used data from the second, third, and fourth waves of the middle school student cohort (N=2,133, N=2,151, N=1,979) of the Korean Children-Youth Panel Survey(KCYPS). Main analyses involved multilevel growth model with interaction terms. The dependent variables were aggression, depression, and social withdrawal. The independent variables were gender and physical education (exercise hours) at school. The control variables were abuse, school-adjustment, annual household income and parents' highest level of education. The major longitudinal findings of this study are as follows: First, there was significant change according to the passage of time only in aggression among externalizing and internalizing problems. Second, gender differences exist in aggression and depression. Third, exercise hours of physical education had a negative relationship with internalizing problems. Fourth, there were no gender differences over time in both externalizing and internalizing problems. Fifth, the interaction between exercise hours of physical education and time was statistically significant for social withdrawal. Sixth, the interaction between exercise hours of physical education and gender was statistically significant for depression. The results of this study may become an academic basis for suggesting policy directions that promote increased exercise hours in physical education classes at school.

  • The health care services are the most basic social institutions that are provided to citizen including disabled persons for improvement of health. However, the study of the difference of health care services according to the speech therapy use in the people with speech-language disorders was insufficient. The aim of this investigation was to compare the awareness of health care services and characteristics of people with speech-language disorders according to speech therapy use. The researchers selected 229 people with language disorder using raw data of National Survey of the Disabled Person (2017). We compared the characteristics and health care services of people with speech-language disorders by distinguishing between speech therapy non-users and speech therapy users. Among the 229 people with language disorder, speech therapy users were 37 persons (16.2%). In comparison with non-users, users were younger, more preschoolers, more family incomes, and intellectual disabilities and autistic disorder were the most common types of disability enrollment. Users had a lower proportion of unmet medical needs than non-users. For the reasons of unmet medical need, there were 6.8% and 6.3% of the "economic reasons" and "communication difficulties" Both users and non-users responded that "disability management services" need to be strengthened by the government. In conclusion, we suggest that access to health care services needs to be increased to lower the barriers of speech therapy use.

  • This study examined the prevalence of and factors associated with unmet care need among community-dwelling middle-aged and older people in Korea. Data were from the 2006 Korean Longitudinal Study on Ageing (KLoSA), a national survey of 10,254 non-institutionalized adults aged 45 or older. Having unmet care needs was defined as needing personal assistance with activities of daily living (ADL) or instrumental activities of daily living (IADL) but having no available helper. Weighted logistic regressions were fitted to examine factors associated with unmet care needs. Overall, 7.3%, 14.5%, and 41.8% of subjects among the middle-aged, younger old, and older old, respectively, reported care needs of these, 34%, 33%,and 24% had unmet needs. Factors associated with unmet needs differed among the three groups: Education and income level were negatively associated with unmet needs among the middle-aged, but living alone was the only factor positively associated with unmet needs in both the younger and older old. The prevalence of and factors associated with unmet care needs differ by life-stage. Needed are home- and community-based care and services to meet the need for personal assistance among the elderly living alone in a community.

  • This study set out to investigate implementation agency effect on participants' self-sufficiency in self-support program. Self-support program's implementation agency consist of civil groups and social welfare corporations. The final sample size was 602 program participants and 18 implementation agencies in Gwangju city, South Korea. Two-level hierarchical linear model was used for analysis. The major findings of this study are as follows. First, civil groups' participants were healthier, more often participated in business model, earned higher monthly income, participated shorter time rather than participants in social welfare corporation. Second, civil groups' participants showed low level of self-sufficiency than participants in social welfare corporations. These results means that self-support policy is not delivered uniformly because front-line implementation agencies develop work habits that influence the outcome of policy. And limitations and implications of this study were discussed with respect to further studies.

  • After industrialization, the labor force participation rates of women, especially married women is drastically increasing. So, this study was designed to analyze the determinants of married women's employment status considered. For this, the determinants of married women's employment status were divided into individual-related, children-related, household-related and job-related variables to establish the research models. Based on this, the following results were drawn from a multinominal logistic regression analysis of the determinants of married women's employment status. First, an analysis of individual-related variable showed that married women had the employment status of labor wages with residence in the center of the city and high academic background. Second, an analysis of children-related variable showed that they had the employment status of labor wages with many their children and no their children under the age of six. Third, an analysis of household-related variable showed that they had the self-employment status of labor wages with nuclear family and few income earners of family members. Finally, an analysis of job-related variable showed that they had the employment status of labor wages when they got a job before they got married, their husband didn't get a job, and their husband worked in a professional field. As for findings stated above, as there was a difference in the determinants of married women's employment status, the ways for improvement in the married women's employment status would be suggested as follows. First, married women with young children have the low employment status, basically, requiring problem-solving ways for this because the housekeeping and child-rearing burden caused by marriage and childbirth are factors that continue to obstruct a job. For this, the flexible working hours system, which housekeeping and child-rearing can harmonize with economic activities like developed countries, needs to be activated. But the activation of such flexible working system will produce actual results under institutional protection, such as a related-protection law. Second, the Leave of Child Care System is debated as one of the most representatively systems that housekeeping can harmonize with economic activities. Now, although the System is legislated, the use is very poor.

  • This study was performed to investigate socioeconomic factors relating to obesity and inadequate nutrient intake in women in low income families residing in Seoul. The subjects were 125 women (aged 41-87 y) recruited from the local health center for free health examination for low income families. The socioeconomic status such as educational level, income level, and housing condition were poor. For subjects aged less than 65 years, the prevalence of obesity was 44% based on BMI (${\geq}\;25\;kg/m^2$), 48% based on WHR (${\geq}\;0.85$), and 50% based on waist circumference (${\geq}\;80\;cm$) and for those more than 65 years, these were greater and 57%, 81%, and 79%, respectively. The main food sources of daily diet were vegetables, grains, and fruits. Energy and other nutrient intake was not adequate for all subjects and the inadequacy was more profound in the elderly, showing percentages of subjects whose intake was less than EAR were greater than 50% for all nutrients except for iron and below RI were also greater than 50% for all nutrients. The prevalence of obesity and nutrient inadequacy were not associated with socioeconomic status in subjects aged less than 65 years, however, obesity was associated with household income and nutrient inadequacy was related to education (vitamin A) and housing status (protein, phosphate, and iron) in the elderly. After adjustment for ages, in the elderly, OR for obesity (BMI ${\geq}$ 25, OR = 12.601; 95% CI = 2.338-67.911) and central obesity (WC ${\geq}$ 80 cm, OR = 4.778; 95% CI = 1.103-20.696) were greater in subjects who earned less than 500 thousand Won per month than who earned more. For inadequate nutrient intake, the OR for inadequate intake of Vitamin A (OR = 4.555; 95% CI = 1.491-13.914) was greater in subjects with no education than those educated. Subjects without her own house had greater risk for inadequate intake for protein (OR = 3.660; 95% CI = 1.118-11.981), phosphate (OR = 3.428; 95% CI = 1.157-10.158), and iron (OR = 3.765; 95% CI = 1.205-11.766) than subjects possessing her house. In elderly females in low income families, the socioeconomic status was associated with the risk for obesity (income level) and inadequate nutrient intake (education level and housing status). More attention on these groups should be given for prevention of obesity and inadequate nutrient intake.

  • This study aimed to investigate consumption status of cooked rice with different grains as well as examine related factors of Koreans. Based on the Korea National Health and Nutrition Examination Survey of the second year (2011) in the fifth stage, we extracted data on 7,190 people aged 1 year and higher who consumed cooked rice with one or more grains and legumes for at least one meal per day. A total of 15,250 meals were analyzed. Approximately 67.6% of subjects consumed cooked rice with different grains for more than one meal. Age was the strongest influencing factor for consuming cooked rice with different grains. Compared with people in their 40s, those aged 19~29 and in their 30s showed lower probabilities (0.5 and 0.6, respectively) of intake of cooked rice with different grains, whereas those in their 50s and 60s showed relatively higher probabilities (1.9 and 5.0, respectively). The intake ratio of cooked rice with different grains was higher in subjects who were females (64.5%), aged 1~18, over 50s, and residing in a metropolis (62.0%). Breakfast (69.6%) showed a higher intake ratio of cooked rice with different grains compared to lunch (49.1%) and dinner (57.9%). Intake of cooked rice with different grains was highest at home (71.2%), whereas it was lowest in restaurants (11.2%). The findings of the current study may be useful in planning dietary guidelines for intake of cooked rice with different grains.

  • The purpose of this study was to examine the oral symptoms, self-rated systemic health state and oral health status of industrial workers in a bid to provide some information on oral health education geared toward industrial workers. The subjects in this study were 294 workers who got a medical checkup in Korea Industrial Health Association in North Gyeongsang Province. Those who felt less inconveniences in the oral cavity led a better quality of life related to oral health in every area except physical handicaps (p<.001, p<.01). The men's OHIP-14 was higher than the women's, and the younger workers led a better quality of life related to oral health in the area of social separation(p<.01), and the married ones did in the area of physical handicaps, mental disorder and social separation(p<.05). And the workers whose household income was larger lived a better quality of life related to oral health in the areas of Psychological discomfort, physical handicaps, mental disorder, social disorder and social separation(p<.05). Those who found themselves to be generally in good health(p<.001, p<.05) and whose subjective oral health state was led a better quality of life in every area(p<.001, p<.05). The findings of the study showed that there were differences in the quality of life according to awareness of oral symptoms, general health status and oral health state.
