유태용,김도영 광운대학교 디지털경영연구소 2003 디지털 경영연구 Vol.9 No.-

이 논문에서는 최근에 사회과학 분야 학술잡지의 개관 논문들에서 사용빈도가 점점 증가되고 있는 통합분석을 상관계수의 통합 방법을 중심으로 소개하고 분석에 사용되는 계산공식과 실제 계산 예를 제시하였다. 개별연구의 결과에 영향을 미치는 표집오차에 대한 추정과 이에 대한 교정을 기술하고, 통합분석을 통하여 조절변인의 존재를 알아보는 방법을 예시하였다. 예측변인과 준거에 대한 측정의 오차와 예측변인의 범위 축소로부터 야기되는 인공물(artifact)에 대한 교정을 다루고, 표집오차, 측정오차, 범위축소를 함께 교정하는 통합분석의 예를 제시하였다. 끝으로, 통합분석이 지니는 제한점과 앞으로 국내에서의 사용 전망을 논의하였다. Recently, meta-analysis is frequently used in studies of social science. The purpose of this article was to introduce the meta-analysis for integrating correlation coefficients and demonstrate computational formulas and examples. We described the estimating procedure for sampling error, it's correction method, and the procedure for identifying moderator. In addition, we dealt with the correction procedures for measurement error in both predictor and criterion and range restriction of predictor. An example of meta-analysis was presented for correcting sampling error, measurement error, and range restriction simultaneously. Finally, the limitation of the meta-analysis and the usability of this analysis in Korea were discussed.

최근에 산업 및 조직심리학에서 직무수행의 구성영역을 확장하는 데 대한 관심이 고조되면서 전통적으로 연구되어 왔던 과업수행 이외에 어려움에 처한 동료를 돕거나 조직의 목표 달성에 윤활유 역할을 할 수 있는 맥락수행의 구성요인과 선행요인에 대한 연구의 필요성이 대두되고 있다. 이 연구의 목적은 기존의 문헌들과 국내 기업장면으로부터 맥락 수행의 행동 예들을 수집한 후, 직무 현직자들의 자기평정에 의한 실증적 자료를 요인분석하여 맥락수행의 구성요인들을 밝히는 데 있다. 이를 위해 집단면접을 통하여 국내 기업장면에서 맥락수행 행동들을 수집하고 국내 및 국외의 문헌 개관을 통하여 총 177개의 맥락수행에 관한 행동 진술문을 얻었다. 다양한 조직에서 근무하는 396명으로부터 얻은 자기평정 결과를 요인분석하여 7개의 맥락수행 구성요인을 도출하였다. 7개 요인은 조직에 대한 헌신, 타인에 대한 도움, 직무에 대한 헌신, 조직규범 준수, 분위기 고취, 정보공유 및 제안, 타인에 대한 배려였다. 이들 중 분위기 고취와 타인에 대한 배려 요인은 외국문헌에서의 구성개념과는 중복이 덜 되는 국내 기업장면에서의 독특한 요인으로 간주할 수 있다. 이러한 결과를 토대로 외국에서 얻어진 맥락수행 구성요인과의 공통점과 차이점을 논의하고 국내에서의 맥락수행에 대한 앞으로의 연구과제를 제시하였다. The purpose of this study was to identify components of contextual performance in work organizations by comprehensive literature review and factor analysis on empirical data from job incumbents. One hundred seventy seven behavioral statements of contextual performance in work organizations were obtained by both literature review and focus group interview. Self-ratings from 396 job incumbents employed in a variety of work organizations were analyzed by factor analysis. Consequently, seven factors were derived: Organizational dedication, Helping others, Job dedication. Following organizational rules, Inspiring work atmosphere, Sharing and proposing information, and Showing consideration. Among 7 factors, Inspiring work atmosphere and Showing Consideration were unique factors found in Korean work organizations and less overlapped with other factors found in other countries or cultures conceptually. Based on the finding, similarity and difference between 7 factors of contextual performance found in this study and the other factors in previous studies were discussed. In addition, future research tasks on contextual performance in Korea were suggested.

Washed rice was coated by spraying aqueous dandelion (Taraxacum officinale) extracts at 20, 30, 40 'Brix and dried at room temperature. The coating procedure was conducted 5 mL/min for 10min. Property changes in the dandelion coated rice and un-coated cooked rice were observed during 2 days of storage. Increasing the coating concentration was associated with lower color values (L, a value) and moisture contents. Sensory and texture properties generally decreased in the cooked rice coated with dandelion more than the control (non-coated rice). But, D-20(20 °Brix of the dandelion concentration) resulted in better textural properties and s ensnry scores for hardness and overall acceptability in cooked rice. Compared to the control, the washed rice roated with 20 °Brix for 0 and 2 days showed better quality in sensory activities, a lower gel consistency and better textural activities. It was concluded that the optimum coating ration of rice and added dandelion extract for cooking were 20 °Brix and 5% respectively, in proportion to the total weight of raw rice.

Objectives : The aims of this study were to identify the intake and following process for subjects at high risk of transition to schizophrenia and to examine the neurocognitive, social, and emotional functions of the subjects compared with healthy controls. Methods : Symptomatic individuals judged at high risk for schizophrenia ('clinical high risk') within Youth Clinic were assessed and followed up. They performed a neurocognitive function test, a social function test and an affective function test. Twenty healthy controls were recruited in this study. Results : Among eighty-two subjects contacted through the Youth clinic, sixteen subjects were judged as the clinical high risk group. Fourteen subjects among the clinical high risk group showed deficits in several domains of neurocognitive functions, such as visual recall memory, verbal short term memory and executive function. Social and affective functions are also impaired in the Cli-nical high risk group compared with healthy controls. Two of 15 subjects (13%) developed a psychotic disorder within 6 months. Conclusion : This study illustrates the state of follow-up study for a clinical high risk group. Despite low numbers and short durations, some impairment of several functions in the clinical high risk group suggests possible predictors of psychosis.

유재두,김종오,윤여헌,고영도,배서영,이정준 대한골절학회 2002 대한골절학회지 Vol.15 No.4

목 적 : 주상골 골절 치료에 사용하는 Herbert/Whipple 나사못의 바람직한 삽입 위치를 알아보고자 하였다. 대상 및 방법 : 4개의 사체에서 분리한 주상골을 이용하여 각 주상골마다 12개씩 주물 모형을 제작하여 대상으로 하였다. 각 모형에서 핀 삽입 안내 장치(jig, Zimmer??)를 이용하여 안내핀(guide wire)을 원위부에서 근위부를 향해 삽입하되 원위부에 A, B, C, D의 4개 근위부에 0, 5, 10의 3개의 지점을 설정하여 총 12가지 방법으로 삽입하였다. 각 모형은 주상골의 장축에 직각인 방향으로 근위부, 요부, 원위부의 세 단면을 만들고 핀 삽입의 흔적과 가장 가까운 피질골 표면과의 거리를 측정하여 이 거리가 대적으로 길 때 안전한 것으로 평가 하였다. 결 과 : 핀 삽입의 흔적과 가장 가까운 표면과의 거리가 근위부에서는 D5, 원위부에서는 C10이 유의하게 길었다. 원위 삽입 위치를 기준으로 하였을 때 근위부에서 C가 유의하게 거리가 길었고 요부, 원위부, 그리고 근위 목표 지점을 기준으로 하였을 때의 측정된 거리는 유의한 차이가 없었다. 결 론 : Herbert/Whipple 나사못의 삽입 위치는 근위부 골절에서는 D5군, 원위부 골절에서는 C5군이 가장 바람직한 위치라고 할 수 있엇고 요부 골절에서는 A0군과 D0군을 제외하면 별 다른 차이 없이 비교적 안전하다고 할 수 있다. 바람직한 위치 선정을 위해서는 근위부의 목표지점보다 원위부의 지점을 정확히 하는 것이 중요하다고 사료된다. Purpose : To evaluate optimal placement of the Herbert/Whipple screw in scaphoid fracture Materials and Methods: Forty eight model molded from four cadaver scaphoids were used for this study. Using the Herbert/Whipple jig, the guide wire was placed distal to proximal into each scaphoid with twelve method which were four entry points and three target points. Guide wire placement was then evaluated with three planes in the proximal, middle, distal planes and distance from the nearest cortex. Results : The most concentric position in the proximal plane was D5, in the middle plane C10. As distal entry point, the most concentric position in proximal plane was C. There were no statistical concentric, as middle, distal plane, and proximal entry point, Conclusion : The most ideal placement were D5 in proximal fractures of the scaphoid, C5 in distal fractures. In waist fractures of the scaphoid, there were relatively safe, except A0 and D0. The position of entry points was more important than that of target points for ideal screw placement.

The electrical properties of Maleate copolymer (C_(18)MA-VE_(2)) and Itaconate copolymer (C_(18)ITA-VE_(2)) Langmuir-Blodgett (LB) films for in-plane were investigated to develop the gas sensor. The C_(18)MA-VE_(2) and C_(18)ITA-VE_(2) were used as sensitive materials and deposition on the slide-glass substrate using LB method which could control the thickness in the molecular order (Å). The current-voltage (I-V) characteristics were measured to investigated the response characteristics in chloroform, acetone, ethanol and methanol gases. The conductivity of sensitive films were 10^(-)7[S/cm] for an in-plane. The change of conductivity was occurred by behavior of organic gases, which mean that the behavior of organic gases could be analyzed using conductivity change and application to gas sensor. In the experimental results, the relation between sensitive films and organic gases could be divided by three-type. Thus, we could analyze the modeling of the response characteristics of organic gases using the conductivity change of sensitive films.

The recreation research held in Korea is mostly based on a social survey method, empolying a theoretical approach to recreation's principles. In the US and Canada, however, the research is more practical and academical, including sociology, psychology, economics, urban engineering, and ecology. A sociological approach to recreation was initiated by T.B.Vebren in 1899. His essential contribution was "The theory of leisure class : an economic study in the evolution of institutions." The so-called leisure sociology supported by experimental data came into being in the 1920s-1930s. Up to now, then, the sociological tendencies in recreation research show the increasing number and areas of applied studies, focused on scientific and contributing to the solution of actual problems of everyday life.
