The study aims at constructing adaptation model, CampusQual, to evaluate the services which Tsinghua provides for Korean Students. The study is based on ServQual’s “expectation-feeling difference” via conducting a survey on satisfaction on their campus life. We implement a survey including 30 questions in 5 sections: demographic statistics, study & information literacy, campus life, social & culture and regulations. Then through CampusQual model, we analyze the Korean students’ adaptation level. CampusQual is a new service model that would enable Korean students to better live and study in universities in China. It also provides feasible suggestions and guidance for administrators on improving campus services for Korean Students.

PurposeAnti-CD19 chimeric antigen receptor T-cell immunotherapy (19CAR-T) has achieved impressive clinical results in adult and pediatric relapsed/refractory (r/r) B-lineage acute lymphoblastic leukemia (B-ALL). However, the application and effect of CAR-T therapy in B-ALL patients with extramedullary relapse are rarely issued even disqualified in some clinical trials. Here, we examined the efficacy of 19CAR-T in patients with both bone marrow and extramedullary involvement.Materials and MethodsCAR-T cells were generated by transfection of primary human T lymphocytes with a lentiviral vector expressing anti-CD19 single chain antibody fragments (scFvs) with the cytoplasmic domains of 4-1BB and CD3ζ, and used to infuse patients diagnosed as having r/r B-ALL with extramedullary origination. Clinical responses were evaluated by the use of bone marrow aspiration, imaging, and flow cytometry. ResultsEight patients received 19CAR-T infusion and all attained complete remission (CR). Only one patient was bridged to hematopoietic stem cell transplantation (HSCT). Although three patients relapsed after infusion, they received 19/22CAR-T infusion sequentially and attained a second remission. To date, five patients are in continuous CR and all eight patients are still alive. The mean follow-up time was 21.9 months, while the 24-month estimated event-free survival is 51.4%. Conclusion19CAR-T therapy can lead to clinical remission for extramedullary relapsed pediatric B-ALL patients. However, the problem of CD19+ relapses after CAR-T remained to be solved. For patients relapsing after CAR-T, a second CAR-T therapy creates another opportunity for remission for subsequent HSCT.

어머니의 완벽주의와 아동의 수면문제의 관계 : 어머니의 우울의 매개효과를 중심으로

Xinyu Gu,Myoung Ho Hyun 동중앙아시아경상학회 2018 한몽경상연구 Vol.29 No.2

본 연구는 어머니의 완벽주의가 아동의 수면에 영향을 미치는 데 어머니의 우울의 매개효과를 확인하려고 하였다. 총 136쌍의 어머니와 아동(남아=67; 여아=69)을 모집하여 설문지를 완료하도록 하였다. 어머니의 평균연령은 35.7(SD=3.618)세였고, 아동의 평균연령은 4.65세였다. 어머니의 완벽주의와 우울은 MPS와 BDI-Ⅱ로 측정하였고, 아 동의 수면문제는 Sleep-Waking Questionnaire로 측정하였다. 연구결과를 보면, 어머니의 총 완벽주의가 어머니의 우 울과 아동의 수면문제와 유의한 상관을 보였고, 이러한 결과가 사회부과 완벽주의와 자기지향 완벽주의에서도 보였 다. 그러나 타인지향 완벽주의가 어머니의 우울과 아동의 수면문제와 유의한 상관을 보이지 않았다. 매개분석 결과는 어머니의 총 완벽주의와 자기지향 완벽주의의 매개효과가 유의하게 나타난 것으로, 사회부과 완벽주의의 부분매개효 과도 유의하게 나타났다. 이러한 결과를 통해 어머니의 완벽주의가 높을수록 아동의 수면에 부정적인 영향을 미치며 이러한 경로에 어머니의 우울을 통해 아동의 수면에 영향을 미친다는 것을 알 수 있다. Present study was to test the role of mother's depression on the relation between mother's perfectionism and children' sleep problem. one hundred and thirty six pairs of mother and children(boys=67; girls=69) were recruited as participants to complete questionnaires. The mean age of children was 4.65(SD=.991), and mothers' was 35.7(SD=3.618). Mother‘’s perfectionism and depression was assessed by MPS and BDI-Ⅱ, children’s sleep problem was estimated by Sleep-Waking Questionnaire. The result that mother's total perfectionism, self-oriented perfectionism and socially prescribed perfectionism can predict children' sleep problem was verified. But mother's other-oriented perfectionism affects children' sleep problem insignificantly. And mother's depression had a significant influence on children' sleep. Result of the mediation model was that mother's depression played a role of mediating effect on the relation between mother's total perfectionism and children' sleep problem. In detail, self-oriented perfection had a perfect mediating effect on the relation between mother's perfectionism and children' sleep problem, and socially prescribed perfectionism played a partial mediating effect on the relation between mother's perfectionism and children' sleep problem. However, other-oriented perfectionism did not has significant correction with children' sleep problem, so the mediating effect of mother's depression did not exist. Present results indicated that mother's perfectionism may not affect children' sleep problem directly but through depression.

재한 중국인 유학생의 내면화된 수치심이 대학생활적응에 미치는 영향

고흔우(Xinyu Gu),구해경(Hae-kyung Koo),조윤경(Yun-Kyung Cho),김희중(Hee-Joong Kim),현명호(Myoung-Ho Hyun) 대한스트레스학회 2017 스트레스硏究 Vol.25 No.4

본 연구는 중국인 유학생을 대상으로 수치심과 대학생활적응과의 관계를 밝히고 이 관계에서 적응적인 인지적 정서조절전략의 효과를 발견하고자 하였다. 서울 소재 한 대학교에 재학 중인 173명의 중국인 유학생을 대상으로 내면화된 수치심, 적응적인 인지적 정서조절전략(수용 및 긍정적 재평가), 대학생활적응을 평가하는 설문을 하였다. 그 결과, 내면화된 수치심과 대학생활적응은 부적 상관이 있었다. 또한 수용과 긍정적 재평가는 내면화된 수치심과 대학생활 적응의 관계를 조절하여, 수용과 긍정적 재평가가 낮은 경우에만 내면화된 수치심이 높으면 대학생활에 잘 적응하지 못하나 수용과 긍정적 재평가가 높으면 내면화된 수치심이 대학생활 적응에 미치는 부정적 효과가 사라졌다. 이러한 결과는 중국인의 유학생활 적응에 임상적 개입을 할 때 내면화된 수치심을 위험요인으로, 적응적인 인지적 정서조절전략을 보호요인으로 고려할 필요성이 있음을 시사한다. Background: The purpose of present study was to examine a relation between internalized shame and adaption to college life of Chinese international students and to identify a moderating role of adaptive cognitive emotion regulation on this relation. Methods: A sample of 173 Chinese international students in Seoul was recruited to answer the questionnaires of internalized shame, adaptive cognitive emotion regulation (acceptance & positive reappraisal) and adaption to college. Results: Internalized shame showed a significant negative correlation with adaption to college. So, the higher internalized shame was, the lower adaption to college showed. And the internalized shame was negative effect on level of adaption to college when level of acceptance was high, but the effect of internalized shame on adaptation to college was disappeared when level of acceptance was low. The similar result was also found in positive reappraisal. So, the moderating effect of acceptance and positive reappraisal on the relation between internalized shame and adaption to college was confirmed. Conclusions: These results suggest that during clinical intervention, practitioners should consider internalized shame as a risk factor and cognitive emotion regulation as a protective factor when dealing with foreign students’ adaption in college.

Liu Xinyu,Yuan Shaoheng,Gu Bo,Chen Qiongxuan,Pu Xinyu,Zhang Jiangtao 한국물리학회 2022 Current Applied Physics Vol.36 No.-

The result of the structural, electronic and thermoelectric performance of monolayer Sb2S2Te, which is a brannew material, is calculated by using the method of full-potential linearized augmented plane-wave (FP-LAPW), and the exchange-correlation potential selected in this paper is generalized gradient approximation (GGA) scheme. There are no negative frequencies in the calculated phonon spectra, which demonstrates that dynamics of monolayer Sb2S2Te is stable in theory. The average value of lattice thermal conductivity (κl) is smaller than that of other thermoelectric (TE) materials, and monolayer Sb2S2Te has larger figure of merit (ZT) comparing with other well-known materials. According to the TE parameters (Seebeck coefficient S, electrical conductivity σ, electronic thermal conductivity κe and lattice thermal conductivity κl) of monolayer Sb2S2Te, an idealized model of thermoelectric generator (TEG) and a realistic model of maximum power point tracking (MPPT) are built. In addition, this paper studies the influence of different temperature zones, different temperature differences, cross sectional area, height and the number of P–N junction on output power and conversion efficiency of TEG. The results of physical calculation and simulation models show that the conversion efficiency of TEG of monolayer Sb2S2Te is larger than or close to that of other well-known materials, and the tracking accuracy of MPPT proposed in this paper is higher than or close to that of other researches.
