Adult stem cells can make identical copies of themselves for long periods of time. They also give rise to many differentiated mature cell types that have characteristic morphology and specialized function. Human adult stem cells are the attractive raw materials for the cell/tissue therapy, however, it is not easy to get from the adult tissues. In the present study, we tried to isolate a cell population derived from human umbilical cord vein which has been discarded after birth. The cells were isolated after treatment of the umbilical vein with collagenase or trypsin. After 3 days of culture, two kinds of cell populations were found consisting of adherent cells with endothelial cell-like and fibroblast-like morphology, respectively. When these cells were subcultured 12 times over a period of 3 months, almost cells appeared uniformly to exhibit fibroblastoid morphology which was different from that of mesenchymal stem cells obtained from human bone marrow The results of RT-PCR analyses showed distinct expression of BMP-4, oct-4, and SCF genes but not of GATA, PAX-6 and Brachyury genes. On immunohistochemical staining, the cells were negative for the von Willebrand factor(vWF), alpha-smooth muscle actin and placental alkaline phosphatase. From these observations, it is suggested that stem-like cells might be present in human umbilical cord vein.

Purpose: The aim of this study was to develop an appropriate nursing information guideline according to corrected age, after investigating parents' concerns about the growth, development, and diseases of their premature infants after discharge from the neonatal intensive care unit (NICU). Methods: The parents of premature infants (birth weight, <2,500 g; gestational age, <37 weeks) who went to a neonatal follow-up clinic after NICU discharge at Seoul St. Mary's Hospital from January 2005 to December 2009, were asked with regard to their concerns about their infants through a questionnaire survey. The results of physical examinations, including body measurements and neurodevelopmental status at 4, 8, 12, and 18 months of corrected age, were retrospectively reviewed in 390 infants. Results: The most common parental concerns were developmental delay, poor growth, and feeding and nutritional problems. Parental concerns about developmental delay, growth failure in improvement in body weight and length, and overweightness were high in specificity but very low in sensitivity. After NICU discharge, 30% of premature infants experienced infectious diseases before 18 months of corrected age, the most common of which was respiratory tract infection. Conclusion: For guiding of premature infants in outpatient day clinics after NICU discharge, it is necessary to identify the parents' highest concerns, to educate them about the possibilities of growth and neurodevelopmental disabilities in their infants and to provide them with handouts containing guidelines on the management of infectious diseases, especially respiratory infections.

Objective: The purpose of this study was to examine children's disclosure to parents in different domains of their daily activities. Methods: The participants were 340 children(100 kindergarteners, 120 3rd graders and 120 6th graders in elementary school) and their mothers in Seoul and Gangwon-do, Korea. The data was analyzed with one-way ANOVA, paired t-test, and MANOVA. Results: First, 3rd graders and 6th graders experienced more daily activities than kindergarteners in most domains. Second, 3rd graders disclosed more than kindergarteners and 6th graders in most domains. The response of mothers with 3rd graders was most similar to their children's response about children's disclosure to parents. Third, the reasons for nondisclosure of children were different according to domains. The reasons for nondisclosure of children that mothers perceived were different from those of their children, especially in the school(institute)-related domain. Conclusion/Implications: The results of this study indicated that the aspects of children's disclosure to parents were different according to domains of their daily activities based on developmental stages. Mothers perceived their children's disclosure differently compared to their children. The results suggest that it is necessary to approach children's disclosure to parents based on domains of daily activities and developmental stages.

Objective: This study aimed to explore the effect of the national preschool curriculum on children's development in Korea, focusing on teachers' daily practice. By comparing the effect of the teachers' curriculum practice to that of quantitatively measured free play, it tried to add practical implications beyond the statistical significance. Methods: Participants were 512 three-year-old children who participated in the Panel Study of Korean Children and their teachers. National curriculum practice and free play time at the age of three was put in the hierarchical linear regression models to discover children's developmental outcomes at the age of four, in domains of language, cognitive development, and social development. Results: Results demonstrated the significant positive influence of national curriculum practice on every domain of developmental outcomes. However, no facilitative influence of free play time was observed. Conclusion/Implications: The importance of teachers' practice of the national curriculum was emphasized. It was implied that the quantity of free play time itself did not assure the sound development of children. Policy implications were discussed regarding teacher practice and education.

일본은 1990년 이후 사회복지제도를 개혁하는 과정에서 이용자본위의 서비스지원, 자기결정에 따른 서비스이용, 자립생활을 지원하는 서비스 등을 새로운 개혁이념으로 제시하면서, 이를 실천하는 제도적 장치의 하나로써 서비스에 대안 이용지원제도를 제시하였으며, 개호보험제도의 개호지원전문원이 당해 역할을 담당하게 되었다. 따라서 개호지원전문원의 도입은 사회복지서비스의 이용과정의 따른 패러다임의 변화를 가져왔다. 즉, 조치제도에 따른 서비스이용의 타율성과 서비스의 이용과정의 복잡성을 고려할 때, 개호지원전문원이라는 단일창구를 통한 서비스의 종합적 상담 지원 그리고 시장기능에 따라서 움직이는 개호지원전문원의 역할을 고려할 때, 요원조고령자의 서비스 선택폭은 크게 확대 강화되었다. 한편, 개호지원전문원제도는 구조적 취약점도 지니고 있다. 즉, 개호지원사업자(소)를 중심으로 한 개호지원기능 개호지원사업자와 서비스사업자간의 병행 운영, 개호지원전문원의 업무내용과 범위의 모호, 개호지원전문원의 겸무허용에 따른 업무과다, 처리역량을 벗어난 사례담당에 따른 어려움, 사회적 지원제도의 부족, 역할과 신분을 초과하는 의무와 처벌 등이 이에 해당된다. 한편, 일본의 개호보험제도와 비슷한 노인수발보장제도와 평가관리원의 도입을 추진하고 있는 한국의 입장에서 보면 이와 같은 개호지원전문원제도의 구조와 특징은 많은 시사점을 줄 수 있을 것으로 본다.

Korean children reading Hangul was studied in children between 2 and 5 years of age. Subjects were 400 young children in each age group from kindergartens or day care centers in 6 cities of Jeon-buk Province. Teachers used a checklist based on Lee, Cha-Suk(2003) to assess children's reading ability. Data were analyzed by frequency, percentage, and $x^2$ using SPSS 10.0 program. Results showed age differences in young children's reading of Hangul. Developmental levels consisted of looking at pictures because of absence of linguistic awareness about words, skipping pages of text without pictures, pronouncing phonemes, being aware of phonemes and of the difference between pictures and print, and knowing that the same phonemes can be applied to different words.

Although a family-centered approach to health care for developmentally disabled children has been advocated, existing systems of care have not adequately addressed the support needs of the family system and the essential role that parents play in the daily care of these children. The overall purpose of this research is to examine family system adaptation to the care of a developmetally disabled child using the Resiliency Model of Family Stress, Adjustement, and Adaptation Framework. Relationships among family system demands (stressors, strains, transitions, child's illness factors) and family system strengths and capabilities(resource of social support) were examined to determine their separate and combined contribution to explanining the variability in family system outcomes (family system coping ). The subject for this study was 46 families who have a child with developmental disabilities(mental retardation and / or autism) from three special educational programs in Seoul, Korea. Results from correlation and hierachial regression analysis revealed that perceived social support operated as a resiliency factor between family stress and coping. Child and family characteristics appeared to be important predictors of perceived social support and coping. In summary, there is evidence that the resource of social support as a family strength and capability was found to improve the family coping. These findings also must be viewed within the context that sample of families of children with disabilities was relatively small and eligible families from support group of special educational program.

Purposes: The purposes of this study are to describe the health problems experienced by VLBW premature infants and their health care services utilization during the first year of life Method: Eighteen mothers of VLBW premature infants completed a survey questionnaire, asking socioeconomic/demographic information, health/developmental problems experienced by their infants, and their use of health care services. Results: Of the 18 infants, 78% experienced respiratory problems such as cold/running nose and wheezing during the first year and 33% experienced gastrointestinal problems such as vomiting, diarrhea and constipation. Twelve (67%) infants visited the emergency department at least one time and 10 infants (56%) were hospitalized at least once during their first year of age. Interestingly, infants without chronic lung disease visited the emergency department more than infants without chronic lung disease (p=.213). Infants living in non-disadvantaged neighborhoods were hospitalized more than infants living in disadvantaged neighborhoods (p=.000). Conclusions: Health care providers should initiate educating mothers, particularly those living in disadvantaged neighborhoods, about post-NICU discharge health care needs of their VLBW premature infants while their infants were still in the NICU so that unnecessary visits to the emergency department and rehospitalizations can be possibly prevented.

In this thesis, Chapter I Introduction suggested the necessity of this research and defined related terms, and Chapter II defined hospice for children and examined the symptoms of pediatric cancers as well as the general characteristics of pediatric cancer patients. In particular, we surveyed the physical condition, psychological and emotional condition, financial condition, environmental aspect, educational aspect and spiritual aspect of pediatric cancer patients’ families, investigated pediatric cancer patients’ parents and siblings with regard to their understanding of the pediatric cancer patients’ death, and lastly considered spiritual care. Chapter III presented summaries and conclusions. In their developmental stage, pediatric cancer patients lack abilities to express themselves and are highly dependent on their parents, so parents who take care of cancer children have to make hard decisions and cancer children’s families are heavily burdened by the situation of preparing their children’s death and sending them away while denying their death, and for this reason they need help from specialists. That is, for pediatric cancer patients, we need highly experienced pediatricians or nurses skilful in managing young terminal patients as well as hospice counseling and family counselors for consulting on family crises. In particular, there is a keen need of child life support specialists. In addition, clergymen’s help is critical for spiritual care to ease the fear and terror of the unknown world, fear of death, etc. Moreover, in order to prevent cancer children from failing to adjust themselves to school life or peer relation after recovery, hospice service should provide cancer children with opportunities to learn school curriculums and associate with friends.
