본 연구는 2008년부터 2017년까지 10년 간 재정지원사업 선정 여부와 횟수에 따른 집단 간 대학성과 차이를 분석하기 위해 집단 간 평균비교(t-test)를 실시하였으며, 재정지원사업의 선정 횟수에 따라 집단 간 대학성과의 차이를 분석하기 위해 분산분석(ANOVA)을 실시하였다. 연구 결과 및 논의를 토대로 한 결론은 다음과 같다. 첫째, 재정지원사업의 선정 여부와 선정 횟수에 따른 집단 간 차이를 분석한 결과, 재정지원사업에 선정되지 않은 대학보다는 선정된 대학이, 재정지원사업에 많이 선정된 대학일수록 대학성과가 긍정적인 것으로 나타났다. 대학은 재정지원사업에 선정되기 위해 일시적인 투자를 하기 보다는 장기적으로 보았을 때 전체적으로 대학성과의 질적 향상을 위해 전략적으로 접근할 필요가 있다. 둘째, 재정지원사업 선정 횟수가 많은 대학을 보면, 여러 사업에 선정되어 지원을 받는 경우가 대다수였다. 재정지원사업의 선정과 이를 통한 대학성과의 향상이 다른 재정지원사업에 선정될 확률을 높여주고, 이후에는 또다시 대학성과가 향상되는 순환구조를 만들어, 재정지원사업의 선정 횟수를 높여주는 원동력이 된 것으로 보인다. 대학들은 선정 여부에 따른 집단 간 차이 분석에서 차이가 큰 변인들을 더욱 더 주의하여 관리할 필요가 있다. 또한 재정지원사업을 통해 대학성과의 향상, 학생 교육역량을 강화하는 타 대학의 제도, 프로그램, 우수사례 등을 적극적으로 벤치마킹하여 각자의 대학 특성에 맞게 접목시켜야 한다. 반면, 재정지원사업에 선정된 대학은 대학성과의 균형적인 성장에 주목할 필요가 있다. 선정된 대학들은 이러한 변인들에 집중하여 한정된 대학 재정 내에서 효율성을 극대화시키기 위해서는 이미 향상된 변인 보다는 취약한 요소를 찾아 투자하여야 한다.

본 연구는 중등교사의 자기표현과 직무만족의 관계에 대한 적응적 인지적 정서조 절의 조절효과를 살펴보고자 하였다. 이를 위하여 서울 및 경기지역의 중·고등학교에 근무하고 있는 교사 333명(남 116명, 여 217명)을 연구대상으로 하여, 자기표현 척도 (Self Expression Scale: SES), 인지적 정서조절 질문지(Cognitive Emotion Regulation Questionnaire: CERQ), 직무만족 척도(Korea Teacher Opinionnaire: KTO)를 측정하였다. 수집된 자료를 바탕으로 측정 변인의 일반적 경향을 알아보기 위해 상관분석을 실시하였고, 변인간의 관계를 알아보기 위해 단순회귀분석을 실시하 였으며, 조절효과를 살펴보기 위해 위계적 회귀분석을 실시하였다. 본 연구의 결과는 다음과 같다. 첫째, 자기표현과 직무만족은 각각 적응적 인지적 정서조절과 정적 상관 이 있는 것으로 나타났고, 자기표현과 직무만족 간의 관계에서도 정적 상관이 있는 것으로 나타났다. 둘째, 자기표현은 직무만족을 유의미하게 예측 하였다. 셋째, 적응적 인지적 정서조절도 직무만족을 유의미하게 예측하는 것으로 나타났다. 넷째, 자기표 현과 직무만족 사이에서 적응적 인지적 정서조절은 조절효과를 보였다. 이상의 연구 결과를 통해 교사를 대상으로 하는 상담 및 교사연수에서 적응적인 방법의 인지적 정 서조절의 사용을 높일 수 있는 개입의 필요성을 제언하였다는데 의의가 있다. In this study, we investigate the moderating effect of adaptive cognitive emotion regulation on the relationship of self-expression and job satisfaction of secondary school teachers. 333 teachers(male; 116, female; 217) in middle and high schools in Seoul and Gyeonggi area were participated in this study. Self-expression scale(SES), Cognitive Emotion Regulation Questionnaire (CERQ), Job Satisfaction Scale (KTO) were used as measurement tools. The collected data were subjected to correlation analysis to determine the general tendencies of the measured variables. Also, simple regression analyses were carried out to determine the relationships between variables. and hierarchical regression analysis was conducted to examine the moderating effect. The results of this study are as follows. First, self-expression and job satisfaction were positively correlated with adaptive cognitive emotion regulation and also the relationship between self-expression and job satisfaction were found to be positively correlated. Second, self-expression significantly predicted job satisfaction. Third, adaptive cognitive emotion regulation was also found to significantly predict job satisfaction. Fourth, adaptive cognitive emotion regulation between self-expression and job satisfaction showed the moderating effect. This results suggested the need for interventions to increase the use of adaptive cognitive emotion regulation through counseling and training for teachers.

이상현,안우상,이우석,최진혁,김선연,Lee, Sang Hyeon,Ahn, Woo Sang,Lee, Woo Seok,Choi, Jin Hyeok,Kim, Seon Yeon 대한방사선치료학회 2017 대한방사선치료학회지 Vol.29 No.2

목 적: Machine Performance Check (MPC)는 Electronic Portal Imaging Device(EPID)를 기반으로 빔 출력을 별도의 설치 없이 측정할 수 있는 장점을 지닌 자체 검사 소프트웨어이다. 본원에서는 MPC와 QA Beamchecker PLUS 간의 일간 빔 출력을 비교 및 상관관계를 분석하여 MPC의 유용성을 확인하고자 하였다. 대상 및 방법: 본 실험을 진행하기 위해 선형가속기(Truebeam 2.5)를 이용하였고, 광자선(6 MV, 10 MV, 15 MV, 6 MV-FFF, 10 MV-FFF), 전자선(6 MeV, 9 MeV, 12 MeV, 16 MeV, 20 MeV) 총 10개의 에너지를 대상으로 5 개월간 치료 전 빔 출력을 MPC와 QA Beamchecker PLUS로 측정하여, 총 80 회의 데이터를 획득하였다. Pearson 상관계수를 사용하여 MPC와 QA Beamchecker PLUS 간의 빔 출력을 비교 및 상관관계를 평가하였다. Pearson 상관계수는 0.8 이상은 아주 강함, 0.6 이상 0.8 미만 강함, 0.4 이상 0.6 미만 보통, 0.2 이상 0.4 미만 약함, 0.2 미만 아주 약함을 의미한다. 결 과: MPC와 QA Beamchecker PLUS 모두 일간 빔 출력 일치도는 2 % 이내로 나타났다. MPC의 빔 출력은 광자선이 $0.29{\pm}0.26%$, 전자선이 $0.30{\pm}0.26%$로 나타났고, QA Beamchecker PLUS의 빔 출력은 광자선이 $0.31{\pm}0.24%$, 전자선이 $0.33{\pm}0.24%$로 나타났다. MPC와 QA Beamchecker PLUS 사이의 Pearson 상관계수는 광자선의 경우 15 MV에서는 아주강함, 6 MV, 10 MV, 6 MV-FFF 그리고 10 MV-FFF에서는 강함으로 나타났고, 전자선의 경우 16 MeV, 20 MeV에서 강함, 9 MeV, 12 MeV에서 보통, 6 MeV에서 아주 약함으로 나타났다. 결 론: MPC는 일간 빔 출력 평가 면에서 광자선과 고에너지 전자선에서는 QA Beamchecker PLUS와 강한 상관관계로 보임을 확인할 수 있었다. 다만, 저에너지 전자선(6 MeV)에서는 낮은 상관관계를 보였지만, 관찰기간동안 MPC, QA Beamchecker PLUS 모두 빔 출력 일치도는 2 % 이내로 일간 빔 출력 확인 용도로는 적절할 것으로 판단된다. MPC는 기존의 일간 빔 출력 측정 도구 보다 빠르게 수행 할 수 있어 사용자 입장에서 효과적인 방법인 것으로 사료된다. Purpose: Machine Performance Check (MPC) is a self-checking software based on the Electronic Portal Imaging Device (EPID) to measure daily beam outputs without external installation. The purpose of this study is to verify the usefulness of MPC by comparing and correlating daily beam output of QA Beamchecker PLUS. Materials and Methods: Linear accelerator (Truebeam 2.5) was used to measure 10 energies which are composed of photon beams(6, 10, 15 MV and 6, 10 MV-FFF) and electron beams(6, 9, 12, 16 and 20 MeV). A total of 80 cycles of data was obtained by measuring beam output measurement before treatment over five months period. The Pearson correlation coefficient was used to evaluate the consistency of the beam output between the MPC and the QA Beamchecker PLUS. In this study, if the Pearson correlation coefficient is; (1) 0.8 or higher, the correlation is very strong (2) between 0.6 and 0.79, the correlation is strong (3) between 0.4 and 0.59, the correlation is moderate (4) between 0.2 and 0.39, the correlation is weak (5) lower than 0.2, the correlation is very weak. Results: Output variations observed between MPC and QA Beamchecker PLUS were within 2 % for photons and electrons. The beam outputs variations of MPC were $0.29{\pm}0.26%$ and $0.30{\pm}0.26%$ for photon and electron beams, respectively. QA Beamchecker PLUS beam outputs were $0.31{\pm}0.24%$ and $0.33{\pm}0.24%$ for photon and electron beams, respectively. The Pearson correlation coefficient between MPC and QA Beamchecker PLUS indicated that photon beams were very strong at 15 MV, and strong at 6 MV, 10 MV, 6 MV-FFF and 10 MV-FFF. For electron beams, the Pearson correlation coefficient were strong at 16 MeV and 20 MeV, moderate at 9 MeV and 12 MeV, and very weak at 6 MeV. Conclusion: MPC showed significantly strong correlation with QA Beamchecker PLUS when testing with photon beams and high-energy electron beams in the evaluation of daily beam output, but the correlation when testing with low-energy electron beams (6 MeV) appeared to be low. However, MPC and QA Beamchecker PLUS are considered to be suitable for checking daily beam output, as they performed within 2 % of beam output consistency during the observation. MPC which can perform faster than the conventional daily beam output measurement tool, is considered to be an effective method for users.

How to control the differentiation of mesenchymal stem cells (MSCs) into vascular lineage cells have still left much unclear even with numerous studies. Most in vitro studies on the differentiation of stem cells have utilized biochemical reagents. However, recent studies show the potentials of physical and co-culturing environments in control of differentiation. Therefore, we first factored out the in vivo conditions into biochemical reagents, co-culture, and physical stimulation. Then combinational effects of those factors on the differentiation of MSCs into vascular lineage cells were studied. For this EGM (R) -2, co-culture, and shear stress were adopted to meet biochemical, neighboring cells, and physical condition, respectively. A total 4 experimental groups were set depending on co-culture and shear stress. Cell density was 1×104cells/cm2 at all group. For the co-cultures, MSCs were mixed with human umbilical vein endothelial cells (HUVECs) in the ratio of 1:2. The 12 dyne/cm2 of shear stress was engaged: 4 hr/ day for 2 days followed by 48 hr after seeding. For the analyses, the immunofluorescent staining and PCR was performed to evaluate the differentiation of MSCs into vascular lineage cells. The co-culture group without shear stress showed the ECs-related markers even on the first day of the culture. And this was more observable on day 4. However, differentiation of MSCs into smooth muscle cells was found dominant when shear stress was engaged even MSCs were cultured with HUVECs and EGM (R) -2. From this study we confirmed that physical stimulation (12 dyne/ cm2 in our study) plays an important role in controlling differentiation of MSCs into vascular lineage cell types when MSCs were co-cultured with ECs.

In this study we investigated the combinational stimulation effects of uniaxial tension and intermittent hydrostatic pressure (IHP) on the differentiation of mesenchymal stem cells (MSCs) into osteoblast without any biochemical agents. For this, we designed a novel bioreactor which can generate not only tensile stimulation and IHP but also combinational stimulation of tension and IHP. We classified experimental groups based on the types of stimulation as follows: (1) NS: no stimulation as a control; (2) IHP: IHP stimulation only (magnitude: 0.1 MPa, intermittent pattern of hydrostatic pressure: 2 min/15 min (on/off), duration: 3 hr/day, for 2 days); (3) TS: tensile stimulation only (magnitude: 3%, frequency: 0.5 Hz, 48 hr in a row); (4) CS: combinational stimulation of (2) and (3). We conducted various biological analyses; DNA contents, ALP activity, Live & Dead staining, F-actin staining, von Kossa staining, and ALP staining. As results, the groups applied mechanical stimulation (IHP, TS, and CS group) showed higher proliferation rate than the group applied no stimulation (NS) at day 8. And amounts of ALP normalized by DNA contents in the groups of TS and IHP were higher than those in CS group at day 5 and day 8, respectively. The highest expressions of ALP and von Kossa staining were observed in IHP group. The expressions of ALP and von Kossa staining in CS were negligible compared with IHP. From this study, we concluded that the single type of mechanical stimulation (IHP or tension) has positive effects but the effect of combinational mechanical stimulation was imperceptible on osteogenesis of MSCs.
