Purpose : To investigate the role of 3D imaging in the sinonasal mass. Materials and Methods : Twenty patientswith sinonasal mass(squamous cell carcinoma[n=6], spindle cell carcinoma[n=1}, angiomatous polyp[n=1}, giant cellreparative granuloma[n=1}, non-Hodgkin's lymphoma[n=1}, melanoma[n=1}, angiofibroma[n=1}, pyocele[n=1}, invertedpapilloma[n=1}) were studied with spiral CT. Reconstruction of surface rendered 3D images and segmentations wereperformed and compared with the 2D image. Results : The 3D images enabled easy understanding of thecharacteristics of the mass in 12 casese. The 3D images displayed pathway of tumor extension in 5 cases and werehelpful in assessing the primary site of the mass in 3 cases. In two cases with encasement of ICA by the mass,assesment of relationship between the mass and vessels were possible through the segmentation. Conclusion : The 3Dimage, as an adjunct to the 2D image, can help to evaluate the virtual appearance of bony change, the degree ofextension of mass, the spreading route, the evaluation of origin site. It also provides valuable 3-dimensionalconception of the mass, especially for the surgeon.

This is a user experience study of factors that should be considered in designing home appliances experience service. Untact services are emerging, but the development of home appliances sector is in early stage. Based on the six factors of Stephen P. Anderson's Creating Pleasurable Interface Model, this study conducted surveys, 1:1 in-depth interviews, and participation observations to measure and analyze user experience. In this study, I compared 4060s and 2030s’s user experience in that the untact services raise the digital alienation among middle-senior-aged. As a result, there were significant differences between the two, including the opposite satisfaction in terms of reliable, usable and pleasurable factors. I hope that this study will be of strategic help in designing future home appliance experience services. 본 연구는 가전제품 체험 서비스를 디자인할 때 고려해야 하는 요인들에 대한 사용자 경험 연구이다. 직원 없는 비대면 형태의 언택트(Untact) 서비스가 확대되고 있지만, 가전제품 분야에 대한 개발은 아직 초기 단계인 실정이다. 이에 본 연구에서는 스티븐 앤더슨(Stephen P. Anderson)의 감성 인터페이스 제작 모형(Creating Pleasurable Interface Model) 6가지 요인을 기반으로 설문 및 1:1 심층 인터뷰, 참여 관찰을 진행하여 가전제품 체험 서비스에 대한 사용자 경험을 측정 및 분석하였다. 연구 대상에 있어서는 언택트 서비스의 문제로 제기되는 중·장년 및 노년 계층의 디지털 소외를 고려하여 4060세대와 2030세대의 사용자 경험을 비교 연구하였다. 그 결과 신뢰성, 사용성, 유희성 측면에서 반대되는 두 세대의 만족도와 그에 대한 세부적인 내용을 확인할 수 있었다. 이에 관해 본 연구에서 제시하는 시사점이 향후 가전제품 체험 서비스를 디자인함에 있어서 전략적인 도움이 되기를 기대한다.

The purpose of this study was to understand pre-service biology teachers" scaffolding of students" explanations in their inquiry teaching practices through their learning approach styles and orientations to teaching science. Four pre-service biology teachers were selected based on their science learning approach styles according to their answers on the R-SPQ-2F questionnaire developed by Biggs, Kember and Leung (2001). Two had deep approaches to learning and the other two had surface approaches to learning. Semi-structured interviews to explore the pre-service teachers" beliefs about science learning and teaching were conducted and their inquiry teaching practicum in the classroom was observed. All data was recorded and transcribed for later analysis. As a result, in the interview, four pre-service teachers showed orientations to teaching science which could effectively support their own learning approach styles. In their inquiry teaching practicum, they all intended to plan and conduct an inquiry- based science teaching, however, they showed significantly different practices in the scaffolding of students" scientific explanations, and these practices were closely linked to their science learning approach styles and orientations to teaching science. Pre-service teachers who had surface approaches to learning showed more teacher-centered explanations and required students to follow the explanation by answering to questions that were mostly factual recall questions. When they asked students to suggest an idea, they revised and compensated for the students" ideas through immediate feedback. Pre-service teachers who had deep approaches to learning asked students to explain or guess about scientific concepts and guided the students in order to help them construct their own explanations by asking for clarification, elaboration, and justification. These results can contribute to suggestions to improve the teaching professionalism of pre-service teachers in science teacher education course.

A Boy with X-Linked Inhibitor of Apoptosis Protein (XIAP) Deficiency as the Initial Presentation of Pure Red Cell Aplasia

X-linked inhibitor of apoptosis protein (XIAP) deficiency is a rare immunodeficiency disorder. A 13-month-old boy was diagnosed with pure red cell aplasia (PRCA) and treated with steroid and cyclosporine. Bone marrow showed diminished erythroid precursors, and positive results for Parvovirus B19 and Cytomegalovirus (CMV) in-fection. A genetic study of Diamond-Blackfan anemia was negative. Five months lat-er, he was admitted due to fever and lymphadenopathy. PCR showed still positive for the Parvovirus, CMV, and Epstein-Barr virus (EBV). He was diagnosed with diffuse large B-cell lymphoma that was positive for EBV. The patient received chemotherapy with R-CHOP, and achieved complete remission. Immunoglobulin (Ig) levels were within an age-matched normal range until the completion of chemotherapy. Subse-quently, he was admitted nine times due to recurrent pneumonia and acute otitis me-dia between two and eight years old. We reanalyzed the Ig levels and lymphocyte subsets: IgG, IgA, and IgM were 30 mg/dL, below 1.0 mg/dL, and 36 mg/dL, res-pectively. Lymphocyte subsets showed nearly absent CD19 (+) cells, but T- and NK cell counts were within normal ranges. A genetic study showed a hemizygous in- frame deletion mutation in exon 4 of the IAP gene without the SH2D1A mutation, consistent with a XIAP deficiency. Therefore, he was diagnosed with XIAP deficiency. Genetic analysis of his mother, aunt and elder sister showed that they were carriers of the same gene mutation. He receives intravenous Ig regularly with follow-up, and still requires a low dose steroid to maintain hemoglobin level. We report XIAP defi-ciency as initial presentation of PRCA.

This study was conducted to explore characteristics of productive and unproductive inquiry in professional learning communities (PLCs). Based on a situated and sociocultural perspective on learning, I examined how two high school science PLCs (L PLC, W PLC) engaged in social interactions to improve teaching. Each PLC participated in 5 full-day professional development sessions (“Studios”) for 6-8 months. In Studios, all science teachers in a school collaborated with researchers and coaches to plan, implement, and debrief lessons. I qualitatively examined the PLCs' discourse in the Studios. Based on the analysis, I found that L PLC mostly showed productive inquiry, while W PLC showed unproductive inquiry. The two PLCs' inquiry showed three contrasting features. First, L PLC actively used classroom data in the inquiry to improve instructional practices, while W PLC did not. Second, L PLC focused on developing and testing instructional practices that could be used across multiple contexts, while W PLC focused on separate strategies that were specific to certain lessons. Finally, L PLC gathered, analyzed, and used multiple kinds of classroom data, while W PLC only used some observational data. This study can inform educational researchers and practitioners about how to study and support teachers' collaborative inquiry in PLCs.

심수연,김용수 한국상담학회 2015 상담학연구 Vol.16 No.5

The purpose of this study is to examine the effects of uncertainty adult attachment on life stress in undergraduates and see if resilience has mediating effects on it. To attain the goal, male and female undergraduates attending two universities located in Gyeonggi-do A city were selected and a survey on adult attachment, resilience, and life stress were conducted by reseacher. Total 210 questionnaire sheets were distributed and collected, and among them, unreliably answered 10 sheets were excluded, and 200 were used for statistical analysis finally. For basic analysis of collected data, SPSS15.0 was used. In addition, to verify hypotheses AMOS 7.0 was used for confirmatory factory analysis, and SEM was utilized to verify mediating effects based on the bootstrap. The findings of this study can be summed up as follows: first, if uncertainty adult attachment (avoidance, anxiety) is higher, life stress becomes higher. Second, if resilience is higher, life stress gets lower. Third, according to the result of analyzing resilience’s mediating effects between uncertainty adult attachment and life stress, resilience has partially mediating effects between uncertainty adult attachment and life stress. This shows that the indirect effects of uncertainty adult attachment on life stress with the mediation of resilience are bigger than the direct effects of uncertainty adult attachment on life stress. The findings of this study imply that it will be effective to intervene with not only uncertainty adult attachment but resilience when counseling undergraduates suffering from life stress and it will be needed to develop programs for improving resilience to reduce life stress. 본 연구는 대학생의 불안정 성인애착이 생활 스트레스에 미치는 영향을 알아보고 회복 탄력성의 매개효과가 있는지를 알아보기 위한 연구이다. 이를 위해 경기도 A시에 소재한 2개 대학교의 남녀 대학생을 대상으로 불안정 성인애착, 회복탄력성, 생활 스트레스에 관한 설문을 실시하였으며, 총 210부의 설문지를 배포하여 회수된 설문지 중 응답이 미비한 10부의 자료를 제외하고 최종 200부를 통계분석 하였다. 수집된 자료는 SPSS 15.0프로그램을 이용하여 기초 자료를 분석하였고, 가설 검증을 위해 AMOS 7.0프로그램을 이용하여 확인적 요인분석, 구조방정식모형(Structural Equation Model: SEM)을 이용한 부트스트랩(bootstrap) 방법을 통한 매개효과 검증을 수행하였다. 본 연구에서 도출된 연구결과는 다음과 같다. 첫째, 불안정 성인애착(회피, 불안)이 클수록 생활 스트레스는 증가하는 것으로 나타났다. 둘째, 회복 탄력성이 클수록 생활스트레스는 감소하는 것으로 나타났다. 셋째, 불안정 성인애착과 생활스트레스에 대한 회복탄력성 매개효과를 분석한 결과, 불안정 성인애착과 생활스트레스에 대한 회복탄력성은 부분매개효과가 있었다. 이는 불안정 성인애착이 생활스트레스에 직접적으로 영향을 주는 것보다 불안정 성인애착이 회복탄력성을 매개로 하여 생활스트레스에 간접적으로 영향을 주는 것이 더 크다는 것을 보여준다. 이러한 연구결과는 생활 스트레스를 받고 있는 대학생들을 상담할 때 불안정 성인애착 뿐 아니라 회복탄력성에도 개입하는 것이 효과적일 수 있으며, 생활 스트레스를 줄이기 위한 회복탄력성 향상 프로그램 개발의 필요성을 시사하고 있다.

심수연,이선영 미래음악교육학회 2023 미래음악교육연구 Vol.8 No.2

The purpose of this paper is to analyze the relationship between creativity, and creative music acheivement of adolescents majoring in Korean Traditional music. To analize these relatioanthip, this study set creativity as independent variable, two types of music performance (imitative performance ,improvisation) as dependent variavle. and set types of mentoring as moderator. The study consisted of two sub-studies. In Study 1, to confirm the effect of creativity on improvisation, the effect of creativity on two types of rhythmic performance tasks (imitation, improvisation) was conducted for 57 high school students majoring in traditional music. In Study 2, mentoring factor was added to the same design as in Study 1 for 43 high school students to test the moderating effect of the mentoring type. The main results of this study are as follows. First, as a result of checking which type of performance creativity predicts among the two types of performance, imitative performance and improvisation, it was found that creativity predicts improvisation. Second, as a result of checking how creativity affects improvisation, Remote Association Ability positively predicted Performance Fluency and Performance Originality of improvisation. On the other hand, Idea Generation Ability was found to negatively predict Performance Originality. Third, as a result of examining the moderating effect of the mentoring type on the effect of creativity on improvisation, the moderating effect was found in the mentoring of the role model function among the three types of mentoring. 본 연구의 목적은 국악전공 청소년의 창의적 특성이 멘토링 유형에 따라 즉흥연주에 어떻 게 영향을 미치는가를 확인하는 것이다. 본 연구는 2개의 연구로 구성되었는데 연구 1에서는 창의적 특성이 즉흥연주에 미치는 영향을 확인하기 위하여 57명의 국악전공 고등학생을 대상 으로 두 유형의 장단 연주과제(모방연주, 즉흥연주)를 제시하고 창의적 특성이 어떤 장단 과 제에 영향을 미치는가를 분석하였다. 연구 2에서는 국악전공 고등학생 43명을 대상으로 연구 1과 동일한 설계에 멘토링(경력 및 심리·사회적기능, 역할모형기능, 예술경력 노출기능)요인을 추가해 독립변수인 창의적 특성이 멘토링 유형의 조절효과에 따라 종속변수인 즉흥성에 미치 는 영향을 분석했다. 연구 결과는 다음과 같다. 첫째, 창의적 특성이 모방연주와 즉흥연주의 두 연주 유형 중 어떠한 유형의 연주를 예측하는가를 확인한 결과 즉흥연주를 예측하는 것으 로 나타났다. 둘째, 창의적 특성이 즉흥연주에 어떻게 영향을 미치는가를 확인한 결과 창의적 특성의 하위요소(아이디어 생성능력, 원격연합능력, 창의적 성향) 중 원격연합능력이 즉흥연주 의 연주유창성과 연주독창성을 긍정적으로 예측하였고, 아이디어 생성능력이 연주독창성을 부정적으로 예측하는 것으로 나타났다. 셋째, 창의적 특성이 즉흥연주에 미치는 영향에서 멘 토링 유형의 조절효과를 검증한 결과 세 가지 유형의 멘토링 중 역할모형 기능의 멘토링에서 조절효과가 나타났다.

As the level of the global economy was enhanced, the amount of meat consumption has increased rapidly. Environmental pollution by livestock excretion has become a big problem worldwide because the number of livestock farms has increased. However, we need to consider the availability of livestock manure as an organic matter resource in sustainable agriculture. Here, we survey the effects of purified liquid fertilizer (PLF) and liquid Bio-fertilizer (LBF) on plant growth. We evaluated the plant length, leaf width, leaf length, chlorophyll concentration (SPAD), stem diameter, and the number, fresh and dry weights, and sugar contents of tomato fruits in tomato under PLF and LBF treatments by comparing to chemical liquid fertilizer (CLF) treatment. Furthermore, the antioxidant activities (total polyphenol, total flavonoid, and DPPH) were evaluated in both liquid fertilizer-treated groups. We observed the increased values of plant length and SPAD in the PLF group, and the width and length of leaves, stem diameter, and fruit number in the LBF group, respectively. However, no significant differences were observed in the fresh and dry weight of tomatoes between PLF and LBF. Overall, the CLF group showed improved plant development in tomatoes compared to PLF and LBF groups developed from livestock. Interestingly, the DPPH scavenging activities were increased in PLF and LBF groups. The PLF group showed the fastest maturity of tomato fruits in both groups.

嶺南地域 出土 豆形土器의 性格

심수연 한국고고학회 2011 한국고고학보 Vol.79 No.-

The mounted dish was used from the Round Attached-rim Pottery Phase to around the beginning of the 1st century AD. It is a type of plain coarse pottery, fired in an oxidizing atmosphere, which consists of a dish and mount attached together. It was first introduced from the Liaoning region into the Korean peninsula during Early Iron Age, along with round attachedrim pottery. In the Yeongnam area, in particular, mounted dishes dating to the Wooden Coffin Tomb Phase (which yields archaic-type grey earthenware) have been identified. Among the characteristics of this pottery type, the inner and outer shape of the mount and the shape of the dish are seen to be temporally sensitive. Each of the types (Aa-Ga, Aa-Na, Ab, Ba-Na and Bb)experienced popularity and decline. Throughout the entire period of their use, types with tall and short mounts were consistently used together (Groups 1, 2 and 3). The time period during which mounted dishes were used in the Yeongnam area can be largely divided into 3 phases, and each of these 3 phases can be further divided, thereby forming a total of 6 phases. Among these, Phases I, II and III, which mark the different time periods, demonstrate significant changes. Firstly, Phase I marks the introductory period during which the mounted dish was not used as a grave good nor in funerary ceremonies. In this period, the mounted dish was made using horizontal tightening, twisted tightening and mount hole widening techniques. Phase II witnessed growth in popularity of the mounted dish, which began to be used as a grave good in the area of the Daegu basin. Increased production and type differentiation and variation are characteristics of this period, and production utilized both new and preexisting techniques, such as mount hole widening, longitudinal and oblique tightening and widening by means of rotation. Phase III witnessed the reduced production and eventual disappearance of this pottery type. The number of examples identified was reduced greatly and the varied production techniques of Phase II were no longer used. In addition, the mounted dish did not make the transition to grey earthenware, but continued to be made with a plain coarse fabric. They were also made in lacquerware and functioned as prestige goods. The mounted dish is typically known to be a kind of ritual vessel, but the possibility that it may have been used as tableware is considered. The dishes with higher mounts would have been used more frequently in rituals. In other words, the differences in mount hight can be seen to reflect differences in function, rather than hierarchy or time period. It is thus possible to suggest that the mounted dish was a type of pottery with highly flexible functions.
