통상적으로 표준적인 최적배분은 층별 조사비용을 고려하여 표본을 배분한다. 만일 조사단위당 비용이 서로 다를 경우 보다 현실적인 배분방법을 고려할 필요가 있다. 즉, 개별 조사단위의 특성에 따라 이익비용비를 최대로 하는 단위를 먼저 표본으로 고려하는 동적배분을 고려하였다. 이러한 관점에서 층별 표본수를 배분하고, 배분된 표본규모에 따라 임의로 표본을 선정하는 방식인 표준적인 최적배분과는 차이가 있다. 이 논문은 약물오용, 낙태, 알콜중독 등과 같은 민감한 특성을 조사하는 층화확률화 응답기법에 대해 각 층별로 표본을 배분할 경우 최적 동적배분을 고려하여 보다 현실적인 문제를 해결하고자 하였으며, 수치적 예제를 통해 동적배분 방법의 효과성을 증명하였다.

According to the Ministry of Health and Welfare, the portion of physical disability was 51.4% which was the highest among the registered disabled in December 2015, followed by visual disability(10.1%), disability of the brain lesions(10.0%), hearing disability(10.0%). The aim of this study is to investigate the types of disability in patients with disabilities visiting the Pediatric Dentistry, Chonbuk National University Dental Hospital in 2016. Of the patients who visited the pediatric dentistry, 196 patients (7.5%) had disabilities, and 19 patients had two or more disabilities. Twelve patients (6.1%) had both disabilities of brain lesion and intellectual disorder. Of the 177 patients with only one disability, 54 patients (30.5%) had physical disorders and 123 patients (69.4%) had psychiatric disorders. In psychiatric disorders, intellectual disorder was the most with 98 patients (55.3%), followed by autistic disorder with 23 patients (12.9%). In physical disorders, disability of brain lesion was the most with 37 patients (20.9%), followed by speech disability with 8 patients (4.5%). In this study, as a result of analyzing the types of disability with the patients who visited the Pediatric Dentistry of Chonbuk National University Dental Hospital, most of them had either intellectual disorder, disability of brain lesion, or autistic disorder. Dentists need to understand their general and dental characteristics to treat children and adolescents with disabilities. Since the most chief complaint of the patients was dental caries, early interventions should be made by dentist to reduce the incidence of the disease.

This study attempted to estimate the level of perceived lack of time in Korean society, to link it to time management and to identify the possible association that accounts for time shortage. I employed the gender perspective in order to reveal the dynamics and complexity of the perception of a lack of time in the population. The sample for the study was drawn from the 1999 and 2009 Korean time diary data collected by the Korean National Statistical Office. From the original data, I selected a sample of second shift families(men and women who are presently working and raising children) living in metropolitan areas(including Seoul and six major urban areas in Korea). The dependent variable was time pressure measured by a single-item question on a four-point likert scale. The results of the study showed that working mothers perceived a greater time shortage as compared to working fathers. The time use pattern showed change during the periods, indicating that people worked fewer hours in paid labor and enjoyed more leisure hours and personal care hours. However, on average, people seemed to have experienced a greater time lack in 2009 as compared to 1999. The results from the ordered logistic regression model revealed that even though there were similarities in the impact of relevant factors, men's perception of a lack of time was more closely linked with their work role and social status, while for women, this perception was influenced by work and family duties. This indicates that Korean working mothers and fathers are facing a double jeopardy of time shortage in terms of combining their work and family roles. As a result, the level of time pressure by gender is converging toward a "never enough" phase. These findings generated policy implications and detailed suggestions.

This paper measured elderly consumers' perceptions of purchasing problems, and classified elderly consumers into 5 categories of purchasing problems using cluster analysis, and analyzed the relationships between the elderly consumers' perception type, socio economic variables, activities of daily living, and activities of healthy living. The data was collected from 500 elderly consumers in Ulsan Metropolitan City. Three clusters were extracted. 56.4% of the sample was included in 'redress and contract problems group', and 22.6% of the sample was included in 'less perception of purchasing problems group, and 21.0% of the sample was included in 'the perception of strong purchasing problems group. The elderly consumers' perception type of purchasing problems were related with socio-economic variables such as sex, existence of a spouse, the number of family living together, the number of children, education, the average monthly household income and allowance, activities of daily living, and activities of healthy living. The redress and contract problems group was found to be of midium level in socio-economic and health status, and included more females and less spouselessness. The perception of less purchasing problems group was found to be the highest level in socio-economic status, and included more males and less spouselessness. The perception of strong purchasing problems group was found to be at the lowest level of socio-economic status.

Although breastfeeding is recognized to be vital to the health and well-being of children and women, the rate of breastsfeeding among Korean women has continuously decreased. One barrier to breastfeeding has been identified to be associated with health care providers. Health care professionals do not give sufficient advice and encouragement, next do hospitals provide supportive environments for breastfeeding by separating infants from mothers or providing formula. The purpose of this study was to investigate prenatal breastfeeding education and infant feeding practices in public health centers and baby-friendly hospitals. A telephone survey was carried out on 57 public health centers located in the Seoul and Chungcheong areas and 13 baby-freindly hospitals from February to April in 2000. Among the public health centers, 43.8% offered periodic prenatal education for pregnant women who visited the centers. Most of them used leaflets or pamphlets developed by the Ministry of Health and Welfare or UNICEF. Twenty six percent of the public health centers developed their own educational materials. All of the 13 baby-friendly hospitals gave additional fluids to infants, did not allow mothers and infants to stay together 24 hours a day, and did not foster the establishment of breatfeeding support groups among the mothers. Most of the baby-friendly hospitals gave artificial teats, did not help mothers initiate breastfeeding within a half-hour of birth. Findings indicate that current practices even in the baby-friendly hospitals are not consistent with the '10 steps to success breastfeeding'. Therefore, deliberate efforts should be made to incorporate adequate breastfeeding education into prenatal program in both public health centers and hospitals, and create environments to support breastfeeding in hospitals, even in baby-friendly hospitals.

우리 생활의 급격한 변화와 서구화 속에서 성인과 함께 아동, 청소년의 비만율이 빠르게 증가하고 있다. 그간 관련 부처와 지자체에서는 이에 대응해 비만관리 정책과 사업을 추진해왔다. 비만 관련 법률은 건강증진법, 어린이식생활 관리특별법, 학교급식법 등 총 25개로 복지부 등 6개 부처가 관장하고 있다. 여러 기관이 각각 추진하다보니 사업의 연계성이 떨어지고 시너지효과를 얻기 어렵다는 지적이 상당하다. 특히, 식생활지침, 연구 조사, 인력 기관 분야의 경우에는 상당부분 중복되어 혼선을 초래할 우려가 높은 것으로 보인다. 단기적으로는 부처간 조정위원회를 통해 비만 관련 정책 및 사업을 조정이 필요하다. 중장기적으로는 부처간 업무조정을 검토해볼 필요도 있다.

Objectives : This study aimed to examine the association between public social expenditure(PSE) and suicides in the 27 countries of the Organization for Economic Cooperation and Development(OECD) from 1980 to 2003. Methods : The age-standardized suicide rates and their annual change(%) were obtained from the OECD Health Data 2007. As a measure of social protection, the PSE(% GDP) was used. The covariates included the annual divorce rate(/100,000 population), fertility rate(number of children/woman aged 15 to 49 years), GDP per capita(US$ PPP), male unemployment rate(%), life expectancy(years) and alcohol consumption(liter/capita) for each country, which were all obtained from the OECD Health Data 2007 and the OECD Social Indicators 2006. Using hierarchical linear models that included these covariates, the effects of PSE on suicides(Model 1) and the annual percent change (Model 2) were examined(Model 3). Also, sub-sample analyses were done for six countries that experienced political/economic transition. Results : We could not find significant effects of PSE on suicides(Model 1), but we observed significantly negative effects on the annual percent change for men and women(Model 2). Such findings were replicated in the sub-sample analysis, and moreover, the effect size was much larger(Model 3). Conclusions : Our finding suggests that social welfare protection can be a pivotal factor for suicide epidemiology, and especially in countries experiencing a social crisis or transition.

본 연구에서는 민감한 변수와 변환된 변수로 구성된 Bar-Lev 등 (2004)의 승법모형에 무관한 양적변수를 새롭게 추가한 승법 무관양적속성 확률화응답모형을 제안하였다. 그리고 무관한 양적변수에 대한 정보를 알 때와 모를 때로 구분하여 민감한 양적속성 추정에 대한 이론적 체계를 마련하고자 하였다. 또한 제안한 승법 무관양적속성 확률화응답모형과 기존의 승법모형인 Eichhorn-Hayre 모형, Bar-Lev 등의 모형, 그리고 Gjestvang-Singh 모형과의 관계를 살펴보았고, Bar-Lev 등의 모형과의 효율성을 비교하였다. 그 결과, 기존의 승법모형들이 제안한 승법 무관양적 속성 확률화응답모형의 특별한 경우임을 확인할 수 있었고, 제안한 모형과 Bar-Lev 등의 모형과의 효율성을 수치적으로 비교한 결과 $C_x({\sigma}_x/{\mu}_x)$값이 작을수록 그리고 $C_z({\sigma}_z/{\mu}_z)$값이 클수록 제안한 승법 무관양적속성 확률 화응답모형이 Bar-Lev 등의 모형보다 효율성이 좋게 나타남을 알 수 있었다. 그리고 제안한 승법 무관양적속성 모형은 $p_1=p$값이 커질수록 또한 ${\mu}_z=1$일 때 보다 ${\mu}_z=0.5$일 때가 더 효율적인 것으로 나타났다.
