Purpose: This study examined the factors that may affect the growth status of preterm infants. Methods: This study included 91 preterm infants born at <37 weeks of gestation (22.9-36.9 weeks of gestation), including 48 (52.7%) males and 43 (47.3%) females. Diet-related data were collected through parental questionnaires, and growth-related data, such as height and weight, were collected through the hospital medical records. Results: No significant difference in weight and growth was observed between early and late preterm infants. On the other hand, smaller averages of all weight z-score (recent weight at 40 weeks of gestation) included lower birth weight, height, and head circumference. On the other hand, infants' birth weight, height, and head circumference in the weight z-score of <0 (<50% in the age-weight growth chart) was smaller than those in the weight z-score of ≥0. Furthermore, neonatal intensive care unit (NICU) hospitalization period and NICU discharge were shorter with growth cessation age in weight z-score of <0. The weight growth velocity was associated with gestational age, birth weight, and medical treatment in the NICU. Thus, parents of preterm infants with low growth rates prefer more community care services for their children. Conclusion: Birth weight, age of preterm infants, and medical treatment in the NICU were factors related to early birth weight growth. Following NICU discharge, poor intake and intake issues were associated with poor growth after 40 weeks of gestation. Therefore, monitoring the growth of preterm infants requires continuous active involvement and supports for growth-promoting factors after NICU discharge.

현행 사학연금법은 공무원연금법 제46조 제1항 제4호 "정원 감소로 퇴직한 때부터 연금 지급" 조항을 준용함에 따라 정원감축 및 폐교에 따른 퇴직을 할 경우 법에 명시된 연금지급 개시연령이 아닌 퇴직 후 5년 이후에 조기연금을 지급하도록 하고 있다. 본 연구의 목적은 현행 지급개시연령 규정의 타당성을 검토하고 개선방안을 제시하는데 있다. 이를 위해 사학연금 지급개시연령 현황 및 사립학교 폐교 현황과 사학연금이 공무원연금법을 준용함으로써 발생하는 문제점 및 현행 규정에 따른 연금지급 시 사학연금재정에 미치는 영향을 분석하고 법 개정의 타당성을 검토하여 개선방안을 모색하였다. 주요 연구결과는 다음과 같다. 65세 정년이 되어 은퇴하지 않고 중도에 퇴직하거나 고용이 취소되어 지급개시연령 보다 훨씬 일찍 조기연금을 지급하게 될 경우에는 퇴직연금 자체가 노후소득보장제도이기 보다는 실업급여의 성격으로 전락하게 되는 측면이 있다. 또한, 폐교에 재직 중인 교직원은 근로가 가능한 연령과 건강상태임에도 불구하고 즉시 연금을 수급하게 됨으로써 재취업을 하지 않을 경우 연금에 대한 의존성이 높아지고 근로유인을 저해할 수 있다. 그리고 최근 잦은 폐교로 인한 연금수급자 과다 발생 및 재정적 지속가능성의 문제가 있다. 또한 사학연금 가입자와 공무원연금 가입자의 특성을 비교하면 중요한 차이점이 발견된다. 국공립학교의 경우에는 해당 학교가 폐교 또는 정원이 감소될 경우 다른 지역 학교로 해당 재직 교직원을 이동 배치하는 등의 대처 방안을 시행하기 때문에 사실상 퇴직하는 사례가 거의 없는 반면, 사학연금 가입자의 경우 공무원연금 가입자에 비해 상대적으로 고용불안에 노출되어 있고, 학령인구 감소 등으로 인해 사립학교 폐교 가능성이 상존하므로 이들에 대한 생활안정대책이 필요하다. 또한 공무원 조직의 개폐 및 정원 감소는 법령으로 정하고 있지만, 사립학교 교직원의 개폐 및 정원의 감소는 사학기관의 특성에 따라 차이가 있다. 그리고 공무원의 경우 공무원연금의 대상이면서도 고용형태의 상대적 취약점을 감안하여 임기제 공무원의 경우 고용보험의 가입이 일부 허용되나, 사학연금 가입자의 경우에는 전면적으로 가입이 제한되어 직역연금 간 형평성 문제가 발생하고 있다. 그리고 국민연금과 비교할 때 다음과 같은 차이점이 있다. 국민연금법의 경우 사업장가입자로 적용받고 있다 하더라도 준용법과 같은 사립학교 폐교 시 조기연금 수급 규정이 없으며, 고용보험법의 적용으로 실직 시 실업급여 등의 대응책이 있긴 하나 연금 수급을 통한 소득보장 수준에는 못 미치는 제도적 보완책을 갖추고 있다. 또한, 국민연금 가입자는 고용보험에 적용되나, 사학연금 가입자는 실업상태에 놓였을 경우 고용보험의 적용을 받지 못한다는 점에서 차이가 존재한다. 이에 다음과 같은 개선방안을 제시하였다. 폐교 시 사학연금 가입자의 생활안정을 위해 고용보험 가입을 검토할 필요가 있고, 재정안정화를 위해 연금을 전액지급하기 보다는 퇴직일부터 지급개시연령까지의 잔여기간에 따라 차등지급하는 방안을 모색해 볼 수 있으며, 고용보험법상의 실업급여 제도를 원용하고 소정의 연금지급기간을 설정하여 연금을 지급하는 방안을 고려할 필요가 있다. 이에 더하여 사학연금제도 내에서 별도의 고용보험기금을 마련하는 방안도 모색해볼 필요가 있다.

The Purpose of this study are to examine the middle-age and old worker's employment rates by age and gender at economic depression and recovery periods after the economic crisis, to identify the main 3causes of the change of the middle-age and old worker's employment rates between two periods, and to analyze whether the determinants affecting the middle-age and old worker's employment may be different by age and gender. For this study, The Annual Korean Labor Panel data(from 1st to 7th) are used. The results show that the employment rates are increased in the economic recovery period, and the difference between male and female employment rates decrease as ages go up. As we predicted, the determinants affecting the middle-age and old worker's employment are different by age and gender. For example, the existence of partner has positive effect on the male employment, but negative effect on female employment. The increases of the middle and old age worker's employment rates in the recovery period are mainly caused by the extension of the individualism(that is, the increases of the middle and upper class workers' employment), rather than the increases of the poor workers' employment rates due to the poverty(that is, the increases of the lower and poor class workers' employment). In the recovery period, comparing to the economic depression periods, the middle-age and old workers in the high class were likely to remain his(her) a good job while those in lower class are more difficult to get a job. This results show that the polarization of middle-age and old worker's employment has been appeared in the recovery periods(after 2001).

In order to analyze factors that support effective health care delivery system, this study aimed to research general public's perception on the functions of medical institutions(based on the levels of treatment: primary care, secondary care, and tertiary care), choices of medical institution when contracted with an unfamiliar disease, and recognition of diseases based on their severities. We collected data using self-administered survey from 400 general public living in Seoul, S. Korea from April 25 to May 18, 2011. The analysis was conducted using frequency analysis, chi-square test, and t-test; we analyzed the data to see if there are differences based on gender, age, and level of education. The result of both recognition of functional differences of medical institutions and selection of medical institutions when contracted with unfamiliar diseases showed that there were no significant differences based on the gender; however there were significant differences when considering the age and education. Looking at the result of the knowledge of the disease classification based on its severity, there were significant differences in age, gender, and education. In order to provide sustainable and effective health care delivery system, utilization of primary care as well as education and promotion regarding the functional differences of medical institutions and classification of disease based on its severity need to be encouraged.

This study explores the pattern of socio-demographic characteristics of divorced couples of international marriage in Korea. This paper focuses on analyzing the effect of dissimilarity between husband and wife on the duration of marriage of divorced couples. It examines whether the differences of socioeconomic characteristics of the married couples are linked to different process within their relationships and duration of marriage. Attention is focused on couple's age and education. Micro-data from divorce registration for the period of 1995-2005 are utilized. Results of analyses reveal the following. First, married couples may have different responses to dissimilarity between the partners according to the combination of nationality of the couples. This indicates that cross-border marriage does not represent the same type of union in different societies or cultures. Second, both dissimilarities of age and education show negative impacts on the marital duration of the couples with foreign wives, but there is a difference in its pattern. Age dissimilarity displays higher impacts on the duration. Third, the result also indicates that the contribution of dissimilarity of age and education on marital duration is relatively small among the couples with foreign husbands.

Purpose : We evaluated and compared clinical and laboratory characteristics of patients with measles in three epidemics(1989~90, 1993~94, and 2000~01) in Daejeon, Korea. Methods : Retrospective analyses were performed using medical records of 520 patients with measles at the Catholic University of Korea, Daejeon St. Mary's Hospital during three epidemics. We divided the subjects into three groups, i.e., those who admitted during 1989~1990(group I, 116 patients), those during 1993~1994(group II, 127 patients), and those during 2000~2001(group III, 277 patients). We compared clinical, demographic and laboratory characteristics among these 3 groups. Results : In age distribution, ratios of under 2 years of age in three groups were 61%, 58% and 57%, respectively with no statistical differences. However there are differences in age distribution above 2 years of age, as 21% in 2~5 years of group I, 28% in 6~9 years of group II, and 21% above 10 years of group III. No statistical differences were present between 3 groups in the male to female ratio, MMR vaccination rate in above 2 years of age, duration of fever, incidence of hepatitis. Hospitalization days(P=0.019) and rate of complications(P=0.012) were longer and higher in group I than in group III. Conclusion : In three epidemics, the second peak age group(except 0~1 year) of children above 2 years of age who had mostly received MMR vaccination showed a trend for increased age with increasing time(statistical difference). This result suggest that secondary vaccine failure may have a role in each epidemics. So, if measles outbreaks is happened in the future, we will have consideration in this aspect.

Purpose : This study was intended to measure seropositivities and the level of mumps- and rubella-specific IgG of MMR vaccinees from 12 to 17 years of age in Korea. Materials and Methods : From May 1996 to July 1996 we obtained sera from students of 1 middle and 2 high schools in Seoul, who were MMR vaccinees from 12 to 17 years of age and had no evidence of immunodeficiency. These 216 study population include 110 males and 106 females. Mumps- and rubella-specific IgG antibody levels were measured by ELISA. Cut-off values for seropositivity were 20 U(Gamma Unit) in mumps and over 0.17 in rubella. Results : 1) As age increased, seropositivities to mumps increased, being 68.4% in 12 year, 79.3% in 13 year, 72.2% in 14 year, 82.0% in 15 year, 87.5% in 16 year, 87.0% in 17 year, which however has no statistical significance. 2) As age increased, the level of mumps-specific IgG antibody(mean+standard deviation, GU) increased, being $52.0{\pm}49.2$ in 12 year, $65.9{\pm}51.4$ in 13 year, $71.1{\pm}66.0$ in 14 year, $67.8{\pm}53.6$ in 15 year, $82.8{\pm}67.8$ in 16 year, $92.0{\pm}68.9$ in 17 year, which however has no statistical significance. 3) As age increased, seropositivities of rubella-specific IgG increased significantly, being 26.3% in 12 year, 20.7% in 13 year, 50.0% in 14 year, 67.2% in 15 year, 66.7% in 16 year, 65.2% in 17 year(P<0.001). 4) As age increased, rubella-specific IgG increased significantly, being $0.13{\pm}0.145$ in 12 year, $0.087{\pm}0.101$ in 13 year, $0.194{\pm}0.168$ in 14 year, $0.260{\pm}0.187$ in 15 year, $0.305{\pm}0.213$ in 16 year, $0.325{\pm}0.221$ in 17 year(P<0.001). There was positive correlation between age and rubella-specific IgG titer(rubella-specific $IgG=0.0517{\times}age-0.5586$, r=0.3752, P<0.001). Conclusion : In adolescent, seropositivities and the level of mumps-specific IgG remained relatively high, but approximately 20% of study population showed seronegativity. Seropositivities and the level of rubella-specific IgG showed the lowest level at 13 years of age and were increased with age after 14 years of age. Further evaluation may be needed to elucidate the cause of these changes of rubella-specific IgG.

The purpose of this study is to compare with work satisfaction, job stress and turnover intention of nurses who work in Comprehensive nursing care service ward, Anshim unit and general ward. The subjects are nurses of general ward, Anshim unit, Comprehensive nursing care service ward from two hospitals in Seoul and one hospital located in Gyeongi province. The summary of the research is as follows. Nurses in a general ward, a Comprehensive nursing care service ward and an Anshim unit don't have meaningful difference in job satisfaction(F=0.50, p=.602), job stress(F=1.12, p=.326), turnover intention.(F=0.02, p=.972). There were some statistic differences of Work satisfaction, job stress and turnover intention according to general characteristics. Henceforth it needs diverse consideration on these factors to reduce turnover intention of nurses.

Purpose : Flow cytometric automated reticulocyte analysis is a superior method to manual reticulocyte counting, with respect to precision and sensitivity. Furthermore, flow cytometric analysis is able to measure immature reticulocyte fraction(IRF) and reticulocyte cellular indices(RCI : cell hemoglobin content : CHr, mean cell volume : MCVr, cell hemoglobin concentration mean : CHCMr, distribytion width : RDWr, HDWr, CHDWr). In this study, we investigated the mean values and clinical significances of IRF and RCI in healthy children and pediatric anemia patients. Methods : IRF and RCI were measured with an automated blood cell analyzer, ADVIA 120(Bayer, USA) using oxazine 750 dye, in 57 healthy children and 61 children with anemia. The anemia group consisted of 27 iron deficiency anemia(IDA) patients and 34 patients with anemia associated with acute infection(AAI). We compared the mean values of IRF and RCI in the control group classified according to age, between anemia groups and the control group, and between the IDA group and the AAI group. Results : For the normal control group, the mean values of IRF, CHr, MCVr and HDWr were higher in neonates when compared to older children. The mean values of IRF and RDWr were significantly higher, and the mean values of CHr and CHCMr were significantly lower in the IDA group when compared to the control group. The mean value of IRF was significantly higher, and the mean value of CHDWr was significantly lower in the AAI group when compared to the control group. The mean values of IRF, CHr and CHCMr were significantly lower in the IDA group when compared to the AAI group. Conclusion : We could determine the normal mean values of IRF and RCI in healthy children classified according to age for understanding of hematopoietic response differences according to age. The evaluation of IRF and RCI by automated reticulocyte analyzer seemed to be accurate and clinically useful for the early diagnosis of anemia and the differentiation of IDA from AAI.
