Chronic granulomatous disease (CGD) is a primary immunodeficiency disease caused by impaired phagocytic function. Hematopoietic stem cell transplantation (HSCT) is a definitive cure for CGD; however, the use of HSCT is limited because of associated problems, including transplantation-related mortality and engraftment failure. We report a case of a patient with CGD who underwent successful HSCT following a targeted busulfan and fludarabine reduced-toxicity myeloablative conditioning. Intravenous busulfan was administered once daily for 4 consecutive days (days -8 to -5), and the target area under the curve was $75,000{\mu}g{\cdot}hr/L$. Fludarabine ($40mg/m^2$) was administered once daily for 6 consecutive days from days -8 to -3. Antithymocyte globulin (2.5 mg/kg/day) was administered from days -4 to -2. The patient underwent successful engraftment and did not have any severe toxicity related to the transplantation. Conditioning with a targeted busulfan and fludarabine regimen could provide a better outcome for HSCT in CGD, with close regulation of the busulfan dose.

주제명은 이용자가 어린이 그림책을 효과적으로 접근하도록 지원한다. 그러나 어린이 그림책은 다른 자료에 비해 표제나 목차와 같이 자료 자체에서 주제명을 선정하기가 어렵다. 또한 텍스트 외에 그림이 주는 정보량이 큰 편이다. 따라서 그림책의 주제접근을 위해서는 별도의 주제명 목록을 작성할 필요가 있다. 그런데 어린이 그림책에 일반 도서용으로 개발된 주제명을 그대로 사용하기는 적절하지 않을 수 있다. 주제명의 유형과 수준이 상이할 수 있기 때문이다. 이에 본 연구에서는 어린이 그림책에 적합한 주제명표를 개발하고자 하였다. 기본 주제명의 선정을 위해서는 영미권에서 발행된 그림책 주제명표를 참고하였는데, 이 과정에서 우리 문화와 언어에 맞도록 기존의 표목을 수정 추가하였다. 또한 그림책의 주요 독자층인 어린이에게 적합한 표목을 선정하기 위해 초등국어사전과 같은 참고자료도 활용하였다. 그리고 시범적으로 구축된 주제명표를 어린이 그림책을 대상으로 한 권장도서 목록에 적용하여, 주제검색이나 브라우징, 도서 추천 등에 활용하는 방안을 제시하였다.

Recently, many childcare centers have actively participated in assessment accreditation. 115 teachers who did participate or did not participate in the accreditation process completed a structured questionnaire, We examined differences between teachers in accredited centers and in non-accredited centers in terms of their individual characteristics, work environment, the utilization of activity materials and the interaction with children. In addition, using the regression model, we analyzed the effects of several characteristics of teachers and childcare center's accreditation on the utilization of activity materials as well as the interactions between teachers and children. The main results of this study are as follows. First, overall, the level of work environment of non-accredited centers was lower than that of accredited centers. Second, compared with teachers in non-accredited centers, teachers in accredited centers used more and higher levels of activity materials, and demonstrated a higher level of interactions with children. Third, including accreditation, use of helpers had a significant effect on the interactions between teacher and children. Forth, not only the accreditation system, but also work hours, work experience, children's age and use of helpers had a significant effect on using materials in childcare activities. Conclusively, understanding the experience of teachers in accredited centers is important hi terms of facilitating the quality of activities and the interactions with children.

Purpose - The main purpose of this paper is to examine the effect of children's age on maternal labor supply in Korea using survival analysis. Specifically, we focus on the career re-interruption of women having children under age 12, which has rarely been studied in the existing literature. Research design, data, and methodology - We use micro data from the Korea Labor and Income Panel Study (KLIPS) surveyed from 1998 to 2016. Instead of using a pre-school child dummy or the number of young children as an explanatory variable, 9 children's age dummies are included to capture the effect of nurturing 0 to 9 years old children. This study estimates the hazard of a woman's exiting the labor market after her first experience of the career interruption, rather than the hazard of the first career interruption itself. A Cox proportional hazard model is applied to numerically capture the impact of children's age on behavioral changes in maternal labor supply. The sample used in this analysis is women between 15 and 54 years old. Most of all, we restrict the sample to women who had at least a child between 0 and 12 years old at the time of quitting their jobs. Results - The Cox proportional hazard model estimates show a strong negative effect of a 0-year-old child on maternal labor supply. Mothers with newborns have a high hazard ratio of labor force exit after the re-entry. The hazard of women with infants is three times higher than those with children aged 10 to 18. Additionally, the results show that not only newborns, but also children in the age of school-entry have a negative impact on their mother's labor supply. Conclusions - The findings reveal that children's ages need to be properly expanded and included when analyzing the effect of children and their ages on married women's labor supply, especially on women's career re-interruption. A large negative effect of 7-year-old children on maternal labor supply found here indicates that supporting mothers with school age children as well as pre-school children is necessary to prevent mothers from leaving the labor market.

Immature ganglion cell (IGC) is known for its relationship with intestinal motility and its impact on postoperative functional outcomes of Hirschsprung's disease (HD). There are few studies on the relationship between intestinal dysmotility and IGC in HD patients. 67 patients pathologically diagnosed with HD and who received definitive operation in Seoul National University Children's Hospital from 2010 to 2011 were included. 10 patients were excluded due to inadequate immunohistochemical staining results. The proximal end of resected ganglionic segment was evaluated with immunohistochemistry examination with MAP-2, a marker of ganglionic cells and bcl-2, a marker of IGCs The median age at operation was 155 (15-4678) day-old. 55 (96.5%) patients positive for bcl-2, were regarded as having IGC, and 2 (3.5%) patients positive for MAP-2 but negative for bcl-2, were regarded as having only mature ganglion cells. In the bcl-2 positive group, there were 7 patients (12.7%) with constipation, 15 patients (27.3%) with soiling, 3 patients (5.5%) with perianal excoriation and 6 patients (10.9%) with medication use. In bcl-2 negative group, intestinal dysmotility was not seen. There was no statistical significance in the two groups. Considering that HD is diagnosed at a young age, the rate of IGC present is very high and it might be inappropriate to relate IGC to functional outcome at young ages.
