Early Head Start (EHS) can provide services to a child and family from pre-birth until the child is three years old. Services are comprehensive, intensive, individualized and flexible according to child and family needs, and integrated with community service delivery systems. The local program designs and operations were developed and carried out within the framework of the Head Start Revised Performance Standards, which included specific provisions for services to pregnant women, infants and toddlers and emphasized prevention, early intervention, safety, and health education. As with preschool Head Start, EHS programs are required to make available 10 percent of their enrollment for infants and toddlers with disabilities as defined by Part C regulations of the state in which the program operated. Quality child care has become a priority for EHS. A majority of EHS children need child care, and the quality is important to their development. An evaluation of EHS in 17 programs selected from the first program cohorts showed that the program had significant and positive impacts on a wide range of parent and child dimensions, some with implications for children's later school success. Among the issues for policy attention identified by American EHS for the Korean system are: - The need to create a comprehensive infant/toddler care system - The need to address access of teachers for young children - The need to improve quality.

Purpose: The normal values for lung resistance and lung capacity of children, as determined by impulse oscillometry (IOS), are different for children of different ethnicities. However, reference values there is no available reference value for Korean preschool children have yet to be determined. The aim of the present study was to determine the normal ranges of IOS parameters in Korean preschool children. Methods: A total of 133 healthy Korean preschool children were selected from 639 children (aged 3 to 6 years) who attended kindergarten in Seongnam, Gyeonggi province, Korea. Healthy children were defined according to the European Respiratory Society (ERS) criteria. All subjects underwent lung function tests using IOS. The relationships between IOS value (respiratory resistance (Rrs) and reactance (Xrs) at 5 and 10 Hz and resonance frequency (RF)) and age, height, and weight were analyzed by simple linear and multiple linear regression analyses. Results: The IOS success rate was 89.5%, yielding data on 119 children. Linear regression identified height as the best predictor of Rrs and Xrs. Using stepwise multiple linear regressions based on age, height, and weight, we determined regression equations and coefficients of determination ($R^2$) for boys ($Rrs_5=1.934-0.009{\times}Height$, $R^2$=12.1%; $Xrs_5=0.774+0.006{\times}Height-0.002{\times}Age$, $R^2$=20.2% and for girls $(Rrs_5=2.201-0.012{\times}Height$, $R^2$=18.2%; $Xrs_5=-0.674+0.004{\times}Height$, $R^2$=10.5%). Conclusion: This study provides reference values for IOS measurements of normal Korean preschool children. These provide a basis for the diagnosis and monitoring of preschool children with a variety of respiratory diseases.

Purpose: To assess the feasibility of the use of spin-echo echo-planar imaging (SE-EPI) magnetic resonance elastography (MRE) in livers of children and young adults. Materials and Methods: Patients (${\leq}20$ years old) who underwent 3T SE-EPI MRE were included retrospectively. Subjects were divided into three groups according to the purpose of the liver MRI: suspicion of fatty liver or focal fat deposition in the liver (FAT group), liver fibrosis after receiving a Kasai operation from biliary atresia (BA group), and hepatic iron deposition after receiving chemotherapy or transfusions (IRON group). Technical failure of MRE was defined when a stiffness map showed no pixel value with a confidence index higher than 95%, and the patients were divided as success and failure groups accordingly. Clinical findings including age, gender, weight, height, and body mass index and magnetic resonance imaging results including proton density fat fraction (PDFF), $T2^*$, and MRE values were assessed. Factors affecting failure of MRE were evaluated and the image quality in wave propagation image and stiffness map was evaluated using the appropriate scores. Results: Among total 240 patients (median 15 years, 211 patients in the FAT, 21 patients in the BA, and 8 patients in the IRON groups), technical failure was noted in six patients in the IRON group (6/8 patients, 75%), while there were no failures noted in the FAT and BA groups. These six patients had $T2^*$ values ranging from 0.9 to 3.8 ms. The image quality scores were not significantly different between the FAT and BA groups (P > 0.999), while the scores were significantly lower in the IRON group (P < 0.001). Conclusion: The 3T SE-EPI MRE in children and young adults had a high technical success rate. The technical failure was occurred in children with decreased $T2^*$ value (${\leq}3.8ms$) from iron deposition.

This study explores the life quality(LQ) of Korean married women compared to Korean married men's LQ, examines personal factors' and home environmental factors' influences to Korean married women's LQ via psychological factors such as social belongingness, positive emotion, self-esteem, and sense of intemal control in causal model, and explores Korean married women's perceived important factors and perceived enhancement required factors in life. The questionnaire was administered to 941 Korean married women and their husbands who have one or more children in Pusan. The results indicated that: 1. The overal and most sub dimensional LQ of Korean married women mark medium level and were lower than that of Korean married men's. Korean married women who is highly educated, keeps efficient communication with their husband, self-esteem, sense of internal control, social belongingness, and positive emotion, and possess high SES and much available resources shows higher LQ than those who doesn't. 2. The efficient communication with husband and available resources have direct and indirect influences on Korean married women's LQ. The psychological mediatory factors of these two variables' influences on women's LQ are such as social belongingness, positive emotion, self-esteem and sense of intemal control. SES has direct influence only and the educational level has indirect influence via social belongingness only on Korean married women's LQ. All these factors explain 58% of Korean married women's LQ variance. 3. Korean married women rank family health, family reconciliation, husband's success, and children's achievement as the very important factors in life. They also rank husbands success, economic abundant, family reconciliation, family health, and their self-actualization as the very required factors for enhancing the given LQ.

한국사회는 IMF로부터 지원을 받는 경제불황기를 경험하면서 많은 변화를 겪어왔다. 이 연구에서는 이러한 급격한 사회변동 이후에 한국사람의 성공에 대한 의식을 살펴보고자 하였다. 이러한 결과를 IMF시대 이전의 선행연구(김의철, 박영신, 1998)와 비교하므로써, 한국사람의 성공에 관련된 사회적 표상을 토착심리학적 시각에서 분석하고 종합하는데 주된 목적이 있다. 분석대상은 총 988명으로, 초 중 고 대학생 481명과 그들의 부(236명) 모(271명)로 구성된 성인 507명이었다. 분석결과, 가장 자랑스러운 성공경험으로 학생은 학업성취를, 성인은 성공적인 가정생활을 지적하였다. 한국사람들에게 성공적인 가정생활이란, 자녀의 교육적 성취와 자녀의 발전 및 화목한 가정을 주로 의미하였다. 성공에 가장 큰 도움을 준 사람은 가족이었는데, 학생의 경우는 부모, 성인의 경우는 배우자가 가장 많았다. 초 중학생에서는 부모가 특히 중요하고, 고등학생 이후는 친구의 중요성이 증가하였다. 어떠한 분야에서든 성공하기 위해 다른 사람으로부터 받은 도움으로서, 학생과 성인 모두 정서적 지원을 가장 중요하게 인식하였다. 성공의 가장 중요한 원인으로서 과반수 정도의 청소년이 자기조절을 지적하였고, 성인 남자는 자기조절을, 성인 여자는 가정환경을 더욱 중요한 것으로 보았다. 이 연구의 결과를 IMF시대 이전의 선행연구 결과와 비교해 볼 때, 국가적인 경제 위기상황 이후에 가족의 중요성에 대한 지각이 더욱 증가하였지만, 학업성취 및 성공적인 가정생활의 중요성, 사회적 지원의 제공자로서 부모와 배우자, 이러한 가족으로부터 정서적 지원의 중요성, 성공의 원인으로서 자기조절에 대한 강조와 같은 핵심적인 결과가 일치하였다. 이와같이 반복적으로 나타난 유사한 결과를 통해, 한국인의 토착적인 성공의식을 종합하고, 이러한 의식의 기저에 있는 신념 및 가치체계에 대해 논의하였다.

The purpose of this study was to determine the success rate of air reduction as the primary treatment of intussusception and whether the success of air reduction could be predicted by plain x-ray. The authors reviewed the medical records of 54 consecutive patients diagnosed with intussusception from Jan 2005 to Dec 2007 at the Department of Surgery, Masan Samsung Hospital. The natures of symptoms and findings of plain abdominal radiography performed in the emergency department (ED) were reviewed. Air reduction failed more frequently (26.3 %) in patients who visited ED more than 24 hours after symptom onset (p=0.009). The mean duration of symptom for operated patients was longer than air reduction group (p=0.01). Also, 3/4 of patients having localized distension of small bowel in the left upper quadrant abdomen had unsuccessful air reduction (p=0.002). In conclusion, the time interval from symptom onset to arrival at ED and localized distension of small bowel in the left upper quadrant abdomen significantly increased the failure rate of air reduction.

As development of exhibition, it has been an important issue to analyze exhibition for the next success of exhibition. A lot of existing researches have focused on the exhibitor's and visitor's satisfaction problem. However, the exhibitor's satisfaction and success of exhibition come from the analysis of exhibition in the network level. Booths composing exhibition are regarded as nodes in network, so the trace of visitors visiting booths can construct the arc of networks. The purpose of this study is to analyze the booth visiting pattern and components of network through social network analysis using data collected in the $17^{th}$ International KIDS & EDU EXPO for Children. This research is the first approach of network-leveled analysis of exhibition, and the result of network analysis is helpful to support the booth arrangement in next exhibition. Our analysis results the following implications. First, Booths with high degree centrality or betweenness centrality should be deployed in the wide space or corner of the exhibition hall. Finally, booths within a block should be deployed in the same space of the exhibition hall to provide convenience to the visitors and to enhance exhibition performance.

To examine the key success factors for long-lasting restaurants, we visited 10 restaurants with 30 or more than 30 years of tradition, located in Seoul and Gyeonggi-do districts, to research these restaurant menus and customer characteristics by observation and interview. The results were analyzed using descriptive statistics. The outstanding feature noted was that each and every restaurant had its own simple and specialized menu. We found that this feature created a virtuous circle that reinforced itself through a positive feedback loop. The simple and specialized menu increased both the cooking efficiency and food quality while it reduced both food and labor costs, this enabled the customers to eat at an affordable price and have generous servings. This lead to customer satisfaction and revisits to the restaurant, which triggered word-of-mouth referral and expansion of their customer base. This in turn created higher operating profit margins that could be reinvested in the business. The secret recipes for cooking, invented by their founders, were passed on from generation to generation. Their customer base included customers of all ages from children to senior people. And their regular customers consisted of neighboring office workers and families traveling from a long distance. We hope that our findings on long-lasting restaurants, especially of the virtuous cycle created due to the simple and specialized menus with secret recipes, will contribute to the development of Korean style long-lasting restaurant model.
