본 연구는 영유아 보육료 지원정책이 보육시설공급률에 따라 노동공급과 출산율에 상이한 영향을 미쳤음을 분석하였다. 구체적으로 보육시설공급률이 높을수록 보육료 지원에 의해 보육시설 입소에 유리한 다자녀모의 경력유지 확률이 증가했을 뿐 아니라 첫째 자녀의 출산율이 높아졌고, 국공립 어린이집의 공급률이 높은 경우에는 보육비 지원 이후 둘째 자녀 출산율도 유의하게 높아졌음을 보여준다. 이는 보육료 지원정책의 효과가 출생순위에 따른 보육시설 입소 우선순위, 거주지역 보육시설의 양적, 질적 공급 정도에 따라 달라짐을 보여준다.

Background: Acute respiratory infections (ARIs), especially pneumonia, remain a major cause of infant mortality worldwide. In Indonesia, pneumonia is the second most common cause of infant and toddler deaths. Exclusive breastfeeding and basic immunization can protect infants and children from contracting pneumonia. Purpose: Our goal was to assess the risk factors for childhood pneumonia in regions with a high prevalence of pneumonia in Indonesia. Methods: This case-control study was conducted between March and April 2019. A total of 176 infants and toddlers aged 10-59 months were enrolled and selected from among patients who visited the community health center. Cases of pneumonia were diagnosed clinically based on the World Health Organization guidelines, and the control was nonpneumonia. Results: The risk factors for the diagnosis of pneumonia included no or nonexclusive breastfeeding (odds ratio [OR], 7.95; 95% confidence interval [CI], 3.52-17.94), incomplete basic immunizations (OR, 4.47; 95% CI, 2.22-8.99), indoor air pollution (OR, 7.12; 95% CI, 3.03-16.70), low birth weight (OR, 3.27; 95% CI, 1.19-8.92), and a high degree of wasting (OR, 2.77; 95% CI, 1.06-7.17). Other variables such as nutritional status (height-for-age z score), age, sex, and educational status of the mother were not risk factors for pneumonia. Conclusion: No or nonexclusive breastfeeding, incomplete basic immunizations, indoor air pollution, a history of low birth weight, and severe malnutrition were risk factors for childhood pneumonia. Breastfeeding was the dominant factor, while sex modified the relationship between exclusive breastfeeding and the incidence of pneumonia.

The purpose of this study was to investigate the effect of the environmental factors on the life-positioning and the self-concept of adolescents from the military families. Subjects were 75 male and 92 female students from Y-middle school in Kye-Ryong city. The results of this study were as follows: First, the life-positioning was influenced by the scholastic achievement of an adolescent and father's rank. Second, the self-concept was influenced by the gender, the order of birth, the scholastic achievement of an adolescent and parent's age, social economic status, and father's rank. Finally, the self-concept of an adolescent was influenced by one's life-positioning.

After the real birth of vascular surgery occurred with the introduction of the first practical arterial prosthesis about 50 years ago, a variety of potential vascular graft had been tested and rejected. Polytetrafluoroethylene [Teflon, PTFE] was first used as a vascular prosthesis in 1957. Thereafter this pros-thesis was first used clinically in 1972 and has subsequently been widely applied as a small and medium sized vessel replacement because it is easy to use and readily available. There are numerous reports of good results about Polytetrafluoroethylene graft. We experienced the three cases of arterial bypass graft using polytetrafluoroethylene vascular pros-thesis. First, 21 years old female patient had suffered from Takayasus disease which affected the left subclavian artery and right subclavian-left axillary extra anatomical bypass graft as done. Second, 64 years old male patient had suffered from Leriche syndrome for 12 years and the left axillofemoral and femorofemoral extra anatomical bypass graft was done. Third, 34 years old male patient had suffered from recurrent Buergers disease which affected the left popliteal artery and the isolated popliteal artery segment bypass graft was done. Relatively satisfactory result was obtained in early post-operative period in all three cases.

This study was formed to propose a theoretical background trying to create a positive delivery experience by understanding college women's subjective accounts (their view and attitude) on delivery. Method: Q- methodology was used to appreciate the highly abstract concept in an objective manner, since delivery can be assessed differently with each experience. Result: There were three types of opinions about the delivery in college women. The first type (matured type) understood delivery to be a precious experience that enables women to gain the value of life through labor pain, and granted then more appreciation to their own mothers. The second type (will type) recognizes delivery as an option rather than an obligation for women. They think women chooses whether or not to experience the process, especially since delivery requires a great deal of responsibility. The third type (positive type) takes delivery as a valuable, worthwhile, and marvelous process that they wish to experience. They are not even afraid of giving birth multiple times. Conclusion: The study explains and allows us to understand college women's overall opinion and attitudes about delivery. Thus this study aids the seizure of an opportunity to build a theoretical base for delivery management.

The Purpose of this study is to explore the conceptions of childhood and the practices about childrearing in the period of the Three States.

Parallel lines are often used to increase production rate in many manufacturing systems where the main line splits into several lines in parallel, and after some operations, they merge into a main line again. Queueing networks with finite buffers have been widely used for modeling and analyzing manufacturing systems. This paper provides an approximation technique for multi-server two-stage networks with merge configuration and blocking which will be a building block for analysis of general manufacturing systems with parallel lines and merge configuration. The main idea of the method is to decompose the original system into subsystems that have two service stations with multiple servers, two buffers and external arrivals to the second stage are allowed. The subsystems are modeled by level dependent quasi-birth-and-death (LDQBD) process.

This study investigated differences of opinion between youth and their parents about having permission to date. Opinions on youth dating permission was gathered from 150 adolescents and their parents. The results were as follows: first, for adolescents there were significant differences of opinion about youth dating permission depending on gender, age, scholastic record, and birth order, but for parents, the difference related to the gender and age of adolescents. Second, the result indicated that adolescents had a greater acceptance of dating permission than their parents, expressing a generational difference. Third, where the scholastic record of subjects was low, where subjects were non-eldest siblings, and where the parents' level of youth dating permission was high, the level of youth dating permission was higher. A main predictor of youth's level of dating permission was the level of the parents about youth dating.

Coexistence of paroxysmal kinesigenic dyskinesia (PKD) with benign infantile convulsion (BIC) and centrotemporal spikes (CTS) is very rare. A 10-year-old girl presented with a 3-year history of frequent attacks of staggering while laughing and of suddenly collapsing while walking. Interictal electroencephalogram (EEG) revealed bilateral CTS, but no changes in EEG were observed during movement. The patient's medical history showed afebrile seizures 6 months after birth, while the family history showed that the patient's mother and relatives on the mother's side had similar dyskinesia. Genetic testing demonstrated that the patient had a heterozygous mutation, c.649_650insC, in the PRRT2 gene. To our knowledge, this constitutes only the second report of a patient with PKD, BIC, CTS, and a PRRT2 mutation.

The fertility rate of Korea has rapidly decreased to the lowest in the World. The fertility rate below replacement fertility level might result in many social problems. First, this study investigated the cause of low fertility rate. Second, the theories of the relationship between fertility rate and women's employment were reviewed. The previous studies suggested that the fertility rate was not always related to women's employment negatively and there was mediating factors between them. Third, the various factors that mediated the negative relationship between fertility rate and women's employment were described in personal, family and social levels. Finally, this study suggested the policies and strategies to solve the low fertility rate problem in Korea.
