      • 인문계 고등학생의 학업성취도와 성격-기질과의 상관성에 관한 연구

        진범수(Bum-Su Chin),윤승현(Seung-Hyun Yun),조수민(Su-Min Cho),함병주(Byung-Ju Ham) 대한사회정신의학회 2005 사회정신의학 Vol.10 No.1

        연구 목적: 고등학생들의 학업 성취도와 성격-기질, 심리적 요인과의 상관관계를 알아보고 그들의 학업 성취도를 예견할 수 있는 요인을 탐색해보고자 하였다. 방 법: 인문계 고등학교 1학년에 재학 중인 205명의 남, 여학생을 대상으로 성격-기질과 심리적 요인들을 자기 보고형 설문지로 조사하 였고 이를 공통으로 실시한 모의고사 성적과 비교하여 고등학생의 성격-기질, 심리적 요인과 학업 성취도와의 관계를 조사하였다. 결 과: 1) 남학생의 경우 여학생보다 학업성취도(Grade-point averages, GPA) 점수가 유의하게 높았다. 2) 전체 학생을 대상으로 시행한 부분상관분석 결과 성격기질검사(Temperament and Character Inventory, TCI)의 기질 차원인 novelty seeking(NS)와 reward dependence(RD)가 GPA와 음의 상관관계를 나타내었고, persistence(P)는 GPA와 유의한 양의 상관관계를 나타내었다. 3) 남학생에서는 RD만이 GPA와 유의한 음의 상관관계를 나타내었다. 여학생의 경우 P와 State-Trait Anxiety Scale(STAIX)의 상태불안 점수가 GPA와 양의 상관관계를 나타내었다. 4) 회귀분석 결과, 남학생에서는 학업성취도를 가장 잘 설명해주는 변인은 RD(F=4.789, p<.05)로, 설명변량은 4.7%였으며, P(F=4.561, p<.05)가 추가됨으로써 설명변량은 8.6%로 증가되었다. 여학생의 경우 회귀분석상 상태불안 점수(F=5.610, p<.05) 만이 유의한 설명변인으로 분석되었다. 결 론: 인문계 고등학생의 GPA는 남학생에서 RD와 P가, 여학생에서 상태불안이 유의한 예언 변인이라는 것을 발견하였다. Objective:This study investigated the relationships between character-temperament and academic achievement in high school students. Method:The study subjects were 205 first-year students of a high school during one academic year(2004). Gradepoint averages(GPA) from the second semester of the first year of high school were obtained as a measure of academic achievement, and all participants completed the Temperament and Character Inventory, Beck depression Inventory, and State-Trait Anxiety Inventory. Results:In general, our results revealed novelty seeking and reward dependence(RD) were negatively correlated with GPA, and persistence(P) was positively correlated with GPA. If data were divided by gender, only RD was negatively correlated with GPA in boys, and P and state anxiety were positively correlated with GPA in girls. In stepwise regression anaysis, RD and P were significant predictive variables for GPA in boys, and trait anxiety was only predictive variable in girls. Conclusion:We were able to delineate relationships between character-temperament and academic achievement.

        고등학생의 인터넷 중독경향과 기질특성의 관계

        진범수(Bum-Su Chin),정은영(Eun-Young Chung),백경아(Kyung-Ah Baek),조하나(Ha-Na Cho),조명선(Myung-Sun Cho) 한국중독정신의학회 2008 중독정신의학 Vol.12 No.2

        Objectives:The purpose of this study was to investigate the relationship between internet addiction tendency and temperament characteristics in high school students. Method:Participants were 280 high school students who resided in Anyang (male/female=148/132). The participants completed a standard questionnaire related to internet use patterns, the Temperament and Character Inventory (TCI), the Korea Internet Addiction Scale (KIAS), and the Beck Depression Inventory (BDI). The subjects were classified into either a risk group or a non-risk group according to their KIAS scores. Results:There was no difference between male and female students in internet addiction tendencies. Compared to the non-risk group, the risk group showed significantly higher ‘novelty seeking’ and ‘harm avoidance’, lower ‘reward dependence’ and ‘persistence’, and a higher BDI score. Persistence was positively correlated with tolerance in the KIAS subscales. Conclusion:This study suggests that high school students with internet addiction tendencies have specific temperament characteristics.

        지각된 통제소재 (Locus of Control)가 통증환자의 심리상태에 미치는 영향

        조선미,진범수,송호정,김찬,한경림,Cho, Sun-Mi,Chin, Bum-Su,Song, Ho-Jeong,Kim, Chan,Han, Gyung-Lim 한국정신신체의학회 2002 정신신체의학 Vol.10 No.2

        연구목적: 통증환자의 인지적 특정은 통증에 대한 지각이나 치료에 대한 반응에서 중요한 역할을 한다. 지각된 통제소재와 같은 인지적 특정이 통증환자의 정서장애나 대처방식과 어떤 관련이 있는지 알아보고자 하였다. 방법: 통증클리닉을 내원하여 치료를 받고 있는 환자 96명을 대상으로 지각된 통제소재를 알아보는 질문지와 미네소타 다면적 인성검사 (MMPI), 대처방식질문지, 주관적으로 통증의 정도와 시간, 괴로움정도, 통제정도를 평정하도록 하여 이 자료를 토대로 분석하였다. 결과: 자료분석결과 환자가 지각하는 통제소재가 내부에 있다고 믿을수록 통증에 대한 통제감이나 통증을 감소시키려는 노력을 했을 때 감소정도가 높은 것으로 보고하였다. 반면 외부통제감이나 우연에 의한 통제감이 높을수록 지각된 통증정도나 통증경험시간, 일상생활 장애정도가 높았다. 또한 내부통제감은 MMPI척도중 자아방어관련척도와 유의한 정적상관을 보였으며, 우울, 불안, 정서억압과 같은 척도와는 부적상관을 보였다. 대처방식 중에서 자기진술 및 감각의 재해석과 같은 방식은 내부통제감를 유의한 정도로 설명하였고 외부통제감과 우연에 의한 통제는 재앙화에 의한 설명변량이 유의한 수준에 이르렀다. 결론: 통증은 비록 신체적 장애이지만 주관적 통증지각이나 일상생활기능정도, 정서적 어려움에는 지각된 통제감과 같은 인지적 요인이 영향을 미친다. 따라서 환자가 통증에 효율적으로 대처하도록 하기 위해서는 내부통제감을 증가시키고 보다 효율적인 대처방식을 사용하도록 인지들 수정해수는 것이 필요하다. Objectives: Cognitive-behavioral scientists have long been interested in how a pain patient's cognition such as locus of control relates to coping and adjustment. The present study examined the relationship of locus of control orientation to pain coping strategies, psychological distress and perceived pain intensity of patients with pain. Methods : Subjects were 96 patients with pain who visited pain clinic. All patients were administered the Multidimensional Health Locus of Control Scales, the Minnesota Multiphasic Personality Inventory, the Coping Strategies Questionnaire, and rating for perceived pain intensity, distress, and duration. Results : Correlational analysis revealed that patients who viewed outcomes as controlled by internality tended to have better ability to control and decrease pain. Also they tended to be less depressed and anxious. Regression analysis indicated that patients having a internal locus of control were more likely to use coping self-statement and reinterpreting pain sensation. Powerful others and chance locus of control orientation were predicted reliance on catastrophizing. Conclusion : The clinical implication of the present study is that cognitive factors of patients with pain such as locus of control influence emotional distress and coping. this study show that these factors should be applied to cognitive behavioral therapeutic intervention.

        Effects of temperature and pressure on properties of SiC-ZrB2 composites prepared by spark plasma sintering

        이정훈,진범수,강명균,김인용,전안균,박진형,김동기,신용덕 한양대학교 세라믹연구소 2013 Journal of Ceramic Processing Research Vol.14 No.4

        Silicon carbide (SiC)-zirconium diboride (ZrB2) composites are produced by subjecting a 60 : 40 vol% mixture of β-SiC powder and ZrB2 matrix to spark plasma sintering (SPS). Sintering is carried out for 60 sec at temperatures of 1400 o C and 1500 o C and uniaxial pressures of 40 MPa, 50 MPa, and 60 MPa, under argon atmosphere. The physical, mechanical, and electrical properties of the sintered SiC-ZrB2 composites are examined. Evidence of reactions between β-SiC and ZrB2 in the SiC-ZrB2 composites sintered under argon atmosphere is not observed by high-resolution x-ray diffraction (HR-XRD) analysis. The trends in the apparent density and flexural strength of the sintered SiC-ZrB2 composites are not dependent on the uniaxial pressure when the sintering temperature is 1500 o C. Among the sintered SiC-ZrB2 composites, the specimen produced at 1500 o C and 50 MPa shows the lowest volume electrical resistivity at room temperature, 0.617 × 10-3Ω·cm. By energy-dispersive spectroscopy (EDS) mapping, it is confirmed that ZrB2-chain formation in the sintered SiC-ZrB2 composites uniformly occurred at 1500 o C and 50 MPa. The flexural strength of the sintered SiC-ZrB2 composites is dependent upon their apparent density, but the volume electrical resistivity is independent of the apparent density. Densification of a sintered SiCZrB2 composite through hot pressing is dependent on the sintering temperature and pressure. However, this study confirms that the densification of SiC-ZrB2 composites through SPS does not depend on the uniaxial pressure.

        SiC-ZrB<SUB>2</SUB>복합체의 특성에 미치는 SPS의 압력영향

        이정훈(Jung-Hoon Lee),진범수(Bm-Soo Jin),신용덕(Yong-Deok Shin) 대한전기학회 2011 전기학회논문지 Vol.60 No.11

        The SiC-ZrB<sub>2</sub>composites were produced by subjecting a 40:60 vol.% mixture of zirconium diboride(ZrB<sub>2</sub>powder and β-silicon carbide (SiC) matrix to spark plasma sintering(SPS). Sintering was carried out for 60sec at 1400℃ (designation as TP145 and TP146), 1500℃(designation as TP155 and TP156) and uniaxial pressure 50MPa , 60MP under argon atmosphere. The physical, electrical, and mechanical properties of the SiC-ZrB<sub>2</sub>composites were examined. The relative density of TP145, TP146, TP155 and TP156 were 94.75%, 94.13%, 97.88% and 95.80%, respectively. Reactions between β-SiC and ZrB<sub>2</sub> were not observed via x-ray diffraction (hereafter, XRD) analysis. The flexural strength, 306.23MPa of TP156 was higher than that, 279.42MPa of TP146 at room temperature, but lower than that, 392.30MPa of TP155. The properties of a SiC-ZrB<sub>2</sub> composites through SPS under argon atmosphere were positive temperature coefficient resistance (hereafter, PTCR) in the range from 25℃ to 500℃. The electrical resistivities of TP145, TP146, TP155 and TP156 were 6.75×10<sup>-4</sup>, 7.22×10<sup>-4</sup>, 6.17×10<sup>-4</sup> and 6.71×10<sup>-4</sup>Ω·cm at 25℃, respectively. The densification of a SiC-ZrB<sub>2</sub> composite through hot pressing depend on the sintering temperature and pressure. However, it is convinced that the densification of a SiC-ZrB<sub>2</sub> composite do not depend on sintering pressure under SPS.
