trans-[FeHCl$(dppe)_2$](1)과 KSeCN의 반응으로부터 trans-[FeH(NCSe)$(dppe)_2$](2)가 합성되었다. 화합물 2-$CH_2Cl_2$의 구조가 X-ray회절법으로 규명되었다. 화합물 2 내에서 수소 리간드가 M-H${\cdots}$H-C유형의 이수소 (dihydro gen) 결합에 참여하고 있다. Reaction of $trans-[FeHCl(dppe)_2]$ (1) with KSeCN led to the formation of $trans-[FeH(NCSe)(dppe)_2](2).$ Compound 2 $·CH_2Cl_2$ was structurally characterized by X-ray diffraction, in which the hydride ligand appears to be involved in the dihydrogen bonding of the type M-H${\cdot}$${\cdot}$${\cdot}$H-C.

지방육종은 전체 암의 1% 정도를 차지할 정도로 성인에 발생하는 연조직육종 중 가장 흔하지만 회음부에서 발생하는 지방육종은 드문 질환으로 술 전 진단이 용이하지 않아서 대부분 수술 후 병리조직학적 검사로 확진된다. 저자는 약 4달전부터 서서히 커지기 시작한 양측 회음부의 무통성 종물을 주소로 내원한 33세 여자의 회음부 지방육종에 대해 완전한 수술적 절제 후 보조 방사선 치료 하지 않고 수술로 완전 절제가 이루어져 국소재발 없이 치료에 성공한 사례를 보고하는 바이다. Liposarcoma is one of the most common soft tissue sarcoma of adults and accounts for 1% in all malignant neoplasm. A liposarcoma of perineal origin is excessively rare, and preoperative diagnosis is difficult. Perineal liposarcoma was diagnosed in a 38-year-old woman. She presented with a large soft lump in the both perineal region of 4 months duration. We report a case of a liposarcoma on perineum which was treated with complete surgical resection without adjuvant radiation therapy. The patient has survived 2 years with no evidence of a recurrence.

Malignant tumors of the maxilla represent about 3-4% of head and neck malignant neoplasm and the origins are maxillary gingiva, hard palate and maxillary sinus. We are to investigate clinical features and results according to various treatment modalities of maxillary malignant tumor to get information for better treatment results. Sixty patients with malignant maxillary tumors treated at Yonsei medical center from 1992 to 1997 were studied retrospectively. They are evaluated according to clinical signs & symptoms, stages at first diagnosis, primary site, histopathologic features, treatment method, recurrence and survival rate with clinical records, biopsy results and CT radiograph. The most common primary site was maxillary sinus and most common histopathology was squamous cell carcinoma. The local recurrence rate was 18% at 5 years, neck failure was 3% and distant metastasis was 18%. Overall survival rate was 78% at 2 years and 69% at 5 years. Failure at primary site is the main problem in the curative treatment. So, to improve survival in these patients efforts should be directed toward improvement of local control.

영유아교사의 교수효능감과 영유아와의 상호작용 관계에서 교사전문성의 매개효과
백지영(Baek, ji young),백영숙(Paik, Young Suk),오현숙(Oh, Hyun Suk) 학습자중심교과교육학회 2021 학습자중심교과교육연구 Vol.21 No.14
목적 본 연구는 영유아교사의 교수효능감이 교사-영유아 상호작용과의 상관은 어떠하며, 교사전문성를 매개로 그 효과를 살펴보는데 목적을 두고 있다. 방법 이를 위하여 K시의 영유아교사 386명을 대상으로 영유아교사의 교수효능감, 교사-영유아 상호작용, 교사전문성관련 변인을 측정하기위한 검사를 실시하였다. 수집된 자료는 PASW 24.0을 활용하여 분석하였으며, 매개효과 검증은 Baron과 Kenny(1986)의 매개효과 검증절차에 따라 교사전문성의 매개효과를 분석하였다. 결과 연구결과는 첫째, 영유아교사의 교수효능감, 교사-영유아 상호작용, 교사전문성 변인 간에 모두 의미 있는 정적상관이 있는 것으로 나타났다. 둘째, 영유아교사의 교수효능감과 영유아 상호작용과의 관계에서 교사전문성의 매개효과를 살펴보기 위해 교수효능감과 교사전문성을 순차적으로 투입한 결과, 영유아교사의 교수효능감은 교사-영유아 상호작용에 더하여 교사전문성을 추가한 연구결과는 통계적으로 의미가 있는 것으로 확인되었다. 결론 따라서 영유아교육현장에서 교수효능감과 전문성을 증진시켜 교사-영유아 상호작용의 질 향상 뿐 아니라 교수효능감과 교사전문성을 증진시킬 수 있는 교사교육이 필요함을 시사한다. Objectives The purpose of this study is to examine the relationship between the teacher s teaching efficacy and the teacher-child interaction, and the effect of teacher expertise as a medium. Methods To this end, a test was conducted to measure the variables related to the teaching efficacy of early childhood teachers, teacher-child interaction, and teacher expertise, targeting 386 early childhood teachers in K city. the collected data was analyzed using PASW 24.0, and the parameters verification were analyzed the mediating effect of teacher expertise in accordance with the verification procedure of Baron and Kenny(1986). Results In the research results, first, it was found that there were significant positive correlations between early childhood teachers teaching efficacy, teacher-child interaction, and teacher expertise. Second, in order to examine the mediating effect of teacher expertise in the relationship between early childhood teachers teaching efficacy and teacher-child interaction, teaching efficacy and teacher expertise were sequentially introduced. In addition, the research results that added teacher expertise were found to be statistically significant. Conclusions Therefore, this suggests that teacher education is needed to improve teaching efficacy and teacher expertise as well as improving the quality of teacher-child interaction by enhancing teaching efficacy and their expertise in the early childhood education sites.

채소섭취 변화단계에 따른 초등학생의 채소 식행동과 기호도

This study was conducted to investigate the vegetable eating behaviors and preferences of elementary school students by stage of change for vegetable intake. The subjects consisted of 191 fourth and fifth grade elementary school students from Gyeonggi province. The stage of change for vegetable intake was categorized into three groups: precontemplation (PC, 18.4%), preparation (P, 43.5%), and action/maintenance (A&M, 48.2%). The trend to eat a variety of foods was more distinctive as the students went from the PC to the A&M stage. The stage of change for vegetable intake was closely related with the kimchi-eating pattern of the students. The A&M group ate more vegetables than the PC group because they liked vegetables and/or wanted to prevent disease. The PC group had a lower tendency to follow recommendations for vegetable eating than the P and A&M groups. The PC group also had an incorrect notion that low vegetable consumption over an extended time would not have a big impact on their health. The vegetables of high preference for the elementary school students were potato, sweet potato, lettuce, radish, perilla leaf, cucumber, and cabbage. The vegetables of low preference were spinach, onion, balloon flower, and green pepper. The PC group had lower preferences for most vegetables than the P and A&M groups. Therefore, careful nutrition education is necessary especially for students in the PC group in order to explain the positive effects of vegetable intake and negative effects of an unbalanced diet. It is also necessary to survey students` tastes consistently and to develop recipes that encourage them to consume more vegetables agreeably.

목적: CXCL13은 B 세포의 귀소 반응에 관여하는 케모카인으로 알려져 있으나 최근 T 세포 관련 염증에 관여한다는 보고가 있고, Th17 세포에서 주로 분비된다는 보고도 있다. 이에 본 연구에서는 소아 천식에서 CXCL13의 임상적인 의의와 기관지과민성, 폐기능과 기도 내 호산구성 염증과의 관련성에 대해 알아보고자 하였다. 방법: 세브란스 어린이 병원에 내원한 만 6세에서 15세 이하의 소아 160명을 대상으로 하였다. 천식 환아는 80명, 대조군은 80명이었다. 전체 대상아에서 폐기능 검사, 메타콜린 기관지 유발 검사를 시행하였고, 혈액 내 호산구 수, 혈청 총 IgE, ECP 및 유도객담 내 호산구 수, ECP 및 CXCL13을 측정하였다. 결과: 유도 객담 내 CXCL13은 천식군에서 대조군에 비해 의미 있게 높았으며(P=0.003), 객담 내 호산구 수(r=0.190, P=0.017) 및 ECP(r=0.285, P=0.002)와 양의 상관관계를 보였다. 혈액 내 호산구 수 및 ECP, 총 IgE와는 통계적 연관성을 보이지 않았고, 폐기능 및 메타콜린 기관지과민성과 도 연관성을 보이지 않았다. 결론: CXCL13은 소아 천식에서 호산구성 염증과 관련하여 기도 내 만성 염증에 역함을 담당할 것으로 사료되며, 유도 객담 CXCL13은 향후 케모카인과 천식의 연관성을 연구하는데 도움이 될 것으로 생각된다. Purpose: CXCL13 is known to be a chemokine delivering B cell to the secondary lymphatic follicles, such as spleen, lymph nodes, and Peyer`s patches. Recently, there have been some reports that CXCL13 is important for T cell inflammation and expressed by Th17 cell which produces IL-17. This study attempted to examine the clinical implication of CXCL13 in children with asthma. Methods: This study included a total of 160 children aged 6 to 15 years who visited Severance Children`s Hospital. There were 80 children with asthma and 80 children without. The pulmonary function test and the methacholine challenge test were performed. Total eosinophi1 count, eosinophil cationic protein (ECP) and total IgE in serum and eosinophils, ECP and CXCL13 in sputum were measured. Results: The mean age of the subjects was 8.3±2.3 years for the asthma group and 9.3±2.5 years for the control group. The male to female ratio was 67.5% and 55.0% respectively. The sputum CXCL13 level for the asthma group was significantly higher than that level for the control group (P=0.003). This significance persisted even after adjustment for age and sex (P=0.010). The sputum CXCL13 level showed a positive correlation with that of sputum eosinophils (r=0.190, P=0.017) and ECP (r=0.285, P=0.002). Conclusion: Our results suggest that CXCL13 may play an important role in the pathophysiology of asthma related to eosinophilic inflammation. Further studies on sputum CXCL13 could help to reveal the role of chemokines in asthma. [Pediatr Allergy Respir Dis(Korea) 2009;19:420-428]
