Objectives : Studies have reported differences between depressed adults and controls in quantitative measures of EEG alpha asymmetry, but, there are few using Korean subjects. So, the present study compared EEG regional alpha asymmetries of patients having major depressive disorder(MDD) and normal controls. Methods : The subjects in this study were 11 unmedicated unipolar depressed patients and 11 non-depressed, age matched controls. Resting EEG(eyes closed and eyes open) was recorded from each participant using 8 scalp electrodes. Beck Depression Inventory(BDI), 17-item Hamilton Depression Rating Scale(HDRS), Zung's Self-Rating Depression Scale(SDS) and Spielberger's State-Trait Anxiety Inventory(STAI) were used to evaluate depression and anxiety symptoms. Results : The severities of depression measured by self-report questionnaires were positively associated with those of anxiety(state and trait) ; The subjects were both anxious and depressed. Anxious-depressed patients differed from controls in alpha asymmetry at T4 channels. They showed evidence of greater activation over right than left temporal site. Conclusion : These findings are consistent with the previousely reported alpha asymmetry of depressed patients with an anxiety disorder. The failure to find the evidence of reduced right parietal activity in depression is presumed to be due to opposing effects of comorbid anxiety on parietotemporal activity.

Objective : Tellegen Absorption Scale(TAS) is an instrument intended to assess hypnotizability and designed to sample absorbing and self-altering experiences, including dissociative experiences. The present study attempted to identify the internal structure of TAS. Methods : One hundred and thirty nine undergraduates completed the Korean version of Tellegen Absorption Scale(TAS-K). Cronbach's alpha was calculated and factor analyses were done. Results : An exploratory principal-components analysis yielded three factors accounting for 31.06% of variance. Factor 1 included dissociative(dissociation-like) experiences, factor 2 tapped imaginative involvements, and factor 3 had to do with perceptual sensitivity. Conclusion : TAS-K may include absorbing and self-altering experiences. 연구목적 : 한국판 텔레겐몰입척도(the Korean Version of Tellegen Absorption Scale ; 이하 TAS-K)는 몰입 경험을 표현한 자기-기술식 설문 척도로서 최면감수성을 반영하는 것으로 알려져 있다. 본 연구에서는 TAS-K의 내적 신뢰도를 포함하여 그 요인구조를 알아보고자 하였다. 방법 : 서울 소재 일 대학교의 학생 139명을 대상으로 TAS-K를 사용하여 설문조사를 시행하였다. 척도의 신뢰도 계산을 위해 내적 일관성 지수인 Cronbach's alpha를 산출하였으며 구성 타당도를 검증하기 위해 요인분석을 실시하였다. 결과 : TAS-K의 Cronbach's $\alpha$의 값이 0.82로 나타나 척도의 내적 신뢰도가 비교적 높은 것으로 나타났다. 요인분석을 실시한 결과에서는 고유치 1.0 이상의 요인들을 추출했을 때 3개의 하위요인이 추출되었는데, 1요인은 일시적인 유사 해리 경험, 2요인은 상상적 몰두, 3 요인은 지각적 민감성 등을 각각 반영하고 있었으며, 총 분산의 31.06%를 설명하였다. 결론 : TAS-K는 비교적 내적 신뢰도가 높았으며, 하위요인은 최면감수성과 관련된 특성들을 반영하고 있었다.

비보존력을 받는 보-부재의 질량행렬, 탄성강도행릴, circulatory비보존력의 방향변화로 인한 load correction강도행력, 그리고 Winkler 및 Pasternak지반강도행렬을 고려한 운동방정식을 유도하고 divergence 및 flutter에 의한 안정성 해석을 수행한다. 또한 내적 및 외적 감쇠계수를 운동방정식에 포함시킴으로써 감쇠효과를 고려하고, 2차 고유치문제의 해법(quadratic eigen problem solution)을 적용하여 flutter에 미치는 영향을 조사한 후, Beck's column, Leipholz's column 및 Hauger's column에 대하여 비보존력의 방향파라미터 ${\alpha}$에 대한 임계하중의 영향, 내적 및 외적 감쇠계수 및 Winkler 및 Pasternak지반에 의한 임계하중의 영향을 각각 조사한다. Equation of motion of non conservative system considering mass matrix, elastic stiffness matrix, load correction stiffness matrix by circulatory force's direction change and Winkler and Pasternak foundation stiffness matrix is derived. Also stability analysis due to the divergence and flutter loads is performed. And the influence of internal and external damping coefficient on flutter load is investigated applying the quadratic eigen problem solution. Additionally the influence of non-conservative force's direction parameter, internal and external damping and Winkler and Pasternak foundation on the critical load of Beck's and Leipholz's and Hauger's columns are investigated.

이준석,방춘석,최일윤,엄주환,Lee, Jun Seok,Bang, Chun Seok,Choe, Il Yun,Eom, Ju Hwan 한국터널지하공간학회 1999 자연, 터널 그리고 지하공간 Vol.1 No.1

The Grout-reinforcement technique which is widely used during the excavation of a shallow or an endangered tunnel can be classified into a couple of groups according to the properties and injection methods of the grout. The reinforcement design will, therefore, take a different approach based on the grouting method under consideration. However, the injection procedure is mainly performed by the experience of the foreman rather than engineering judgement , specifically the permeation grouting through the rock joints and its reinforcement effect Is not fully under-stood during the design stage, In this study, the anisotropic material properties of the grout-reinforced rock masses are derived from the concept of composite materials and the effect of intact rock, vertical grouting and permeation grouting is, therefore, fully accounted for. Through the parametric studies on the characteristics of rock joints, intact rock and grouting materials, various case studies have been considered. The results, illustrated via the design charts, can be directly used during the reinforcement design.
