The need to assess preoperative psychological characteristics of orthoganathic surgery patients has recently been recognized. Fifty six patients were involved in this study, they were investigated in the preoperative psychosocial aspects. Korean Version Eysenk Personality Questionaire and Korean Version Tennessee Self-Concept Scale were used for psychological test. The results were as follows : 1. There was no significant difference of sex and age in the personality diamension, the selfconcept scale, and the preoperative tests(P>0.05). 2. 37% of subjects showed phonetic problem, 60% masticatory problem and 56% social problem for facial deformity. The first choice was the face in the order of correctionfor mastication, phonation and face. And 83% of the subjects forecasted the change in their face after surgical correction, The answer was generally vague. 64% of the subjects expected their personality to become more lively as a result of their operation. 3. Total positive self score and personal self score were less improved in the groups with high scores of toughmindness and neuroticism(P<0.05), degree of suffering was increased in the group with high scores of neuroticism(P<0.05). 4. Degree of subjective deformity, self-consciousness, and degree of dissimilarity were more improved in the group of intraversion, there was a significant correlation with degree of dissimilarity in the group with high score of toughmindness(r=-.64, P<0.05). 5. There was a significant correlation with the forecast of change in the groups with high score in extraversion(r=.59, P<0.01) and with low score in neuroticism(r=-.39, P<0.05).

김효남,정완호,정진우,양일호,김영신 한국교원대학교 과학교육연구소 1999 청람과학교육연구논총 Vol.9 No.1

이 연구는 우리 나라 학생들의 과학의 정의적 특성의 성취 수준을 종단적으로 분석하여 국가 수준에서 과학교육 성과를 가늠해 봄으로써, 과학교육의 질을 향상시킬 수 있는 과학교육 정책의 기초자료를 제공하는데 그 목적이 있다. 이를 위하여 1997년 2월에 초중고학생 3603명, 1999년 3월에 초중고학생 4737명을 대상으로 과학의 정의적 특성을 조사하였다. 본 연구의 결과는 학교급별 과학의 정의적 특성의 성취 수준이 초등학교에서 중학교까지 통계적으로 유의미하게(p<.05) 하락 한 후 고등학교에서 상승하는 것으로 나타났다. 또한, 남학생이 여학생보다 통계적으로 유의미하게 높게 나타났다(p<.05). 남녀간의 성취수준의 차이는 학년이 올라갈수록 감소하는 것으로 나타났다. 지역별로는 소도시보다 대도시가 높게 나타났으며, 시간이 지날수록 그 차이가 커지는 것으로 나타났다. 1997년과 1999년의 성취 수준을 비교해보면 1999년의 성취수준이 통계적으로 유의미하게 낮게 나타났다. 또한, 국가수준의 과학에 대한 성취도를 분석할 수 있는 모니터 과정이 계속적으로 이루어지길 기대한다. The purpose of this study was to longitudinally analyze Korean students' trend on science-related affective characteristics and provide descriptive data for improving the quality of Korean science education. In this longitudinal study, 3603 students and 4737 students were sampled in elementary and secondary schools, respectively in January 1997 and March 1998. The result showed that students' affective characteristics were decreased with statistical significance(p<0.05) during elementary and junior high school periods, but students' affective characteristics were increased during high school period. Affective characteristics of male were significantly higher than those of females' (p<0.05). Difference on affective characteristics between female and male students was being decreased by increasing grades. Students' affective characteristics in metropolitan areas were significantly higher than those in regional areas and difference between them was increased in 1999 comparing to 1997. The students' affective characteristics in 1999 were lower than those in 1997 totally.

Objectives : The objective of this study was to evaluate an association between posttraumatic stress disorder (PTSD) and altered immunity m North Korean defectors who were more likely to develop medical conditions and other stress-related psychiatric disorders. Methods : Twenty-four North Korean defectors with PTSD and twenty-two controls without PTSD were recruited from the resettlement and training center for North Korean defectors in South Korea. Peripheral T lymphocyte subsets, natural killer(NK) cells, NK cell activity and plasma hormones (ACTH and cortisol) were obtained from all subjects. We also applied the Hamilton Rating Scale for Depression (HAM-D) and Hamilton Rating Scale for Anxiety (HAM-A) for all subjects. Results : We found NK cell activity was relatively lower than number of NK cells in North Korean defectors with PTSD. Subjects with PTSD had higher HAM-D and HAM-A scores than controls. However, there were no statistical differences in ACTH. cortisol, CD3, CD4, CD8, CD4/CD8 ratio, CD19 and CD56 between the two groups. Conclusion : These findings suggest North Korean defectors with PTSD show higher levels of depression, anxiety and impaired or weak immune function in NK cells.

Hyo Jeong Oh,Hak Ryul Kim,Ki Eun Hwang,So Young Kim,Sun Ho Ahn,Sei Hoon Yang,Eun Taik Jeong 대한내과학회 2006 The Korean Journal of Internal Medicine Vol.21 No.4

A 44-year-old Korean male died of rapidly progressive respiratory failure and refractory hypoxemia in 8 days after being admitted with a fever and dyspnea. The patient was diagnosed with pseudomembranous necrotizing tracheobronchial aspergillosis by fibroptic bronchoscopy and it was not related to an invasion of the pulmonary parenchyma. To the best of our knowledge, this case represents a patient with pseudomembranous necrotizing tracheobronchial aspergillosis that developed in an immunocompetent host, rapidly resulting in airway obstruction with acute respiratory failure and refractory hypoxemia without an invasion of the pulmonary parenchyma.

We isolated human mesenchymal stem cells (hMSC) from dental pulp. These cells are multipotent and serve as precursors for various mesoderm-type cells such as osteoblasts, chondroblasts and adipocytes, as well as several other types of cells. This study investigated the possible role of gangliosides in osteoblast differentiation of hMSCs. Gangliosides, which exist in glycosphingolipid-enriched domains on the cell membrane The role of gangliosides that play in osteoblastogenesis is not yet clearly understood. Therefore, in this study, We investigated the relationship between gangliosides and osteoblast differentiation of human mesenchymal stem cells (hMSCs). The results of high-performance thin-layer chromatography (HPTLC) showed that ganglioside GD1a expression was increased during the differentiation of hMSCs into osteoblasts. Furthermore, we showed that involvement of alkaline phosphate (ALP) with GD1a by immunostaining. Taken together, these results suggest that gangliosides GD1a may play a role in the osteoblast differentiation process of hMSCs.

Background and ObjectivesThere are limited data regarding the clinical efficacy of the proximal optimization technique (POT) in the treatment of coronary bifurcation lesions. We investigated the influence of POT on the clinical outcomes of patients with coronary bifurcation lesions. MethodsWe enrolled a total of 1,191 patients with a bifurcation lesion with a side branch (SB) diameter ≥2.5 mm treated with a drug-eluting stent from 18 centers between January 2003 and December 2009. The primary outcome was major adverse cardiac events (MACEs: cardiac death, myocardial infarction or target lesion revascularization [TLR]). We performed one-to-many (1:N) propensity score matching with non-fixed matching ratio. ResultsPOT was performed in 252 patients. During follow-up (median 37 months), the incidence of MACE was lower in the POT group than it was in the non-POT group (adjusted hazard ratio, 0.43; 95% confidence interval [CI], 0.24–0.79; p=0.006). After propensity score matching, these were 0.34; 95% CI, 0.17–0.69; p=0.003 for MACE and 0.37; 95% CI, 0.17–0.78; p=0.01 for TLR. The use of POT was associated with significantly lower TLR in patients treated without kissing ballooning, but was not in those who underwent kissing ballooning (p for interaction=0.03). ConclusionsIn coronary bifurcation lesions with a large SB, POT may be beneficial to improve long-term clinical outcome, particularly in patients treated without kissing ballooning during the procedure.
