본 연구의 목적은 직장인의 주관적 안녕감에 대한 업무 효능감/의미감의 역할을 조사하는 것이다. 이를 위해 본 연구는 긍정 정서, 부정 정서, 삶의 만족과 같은 주관적 안녕감의 구성요인들과 업무 효능감, 업무 의미감으로 구성된 이론모형을 제안하였다. 설문방법을 이용하여 자료를 수집하였고, 구조방정식모형을 사용하여 자료를 분석하였다. 분석결과 첫째, 예상대로 긍정 정서는 삶의 만족에 긍정적인 영향을 미치는 반면 부정 정서는 삶의 만족에 부정적인 영향을 미치는 것으로 나타났다. 둘째, 업무 효능감과 업무 의미감은 긍정/부정 정서와 삶의 만족 간의 관계를 매개하는 것으로 나타났다. 업무 효능감 및 의미감이 직장인의 행복감에 의미 있는 영향을 미친다는 본 연구의 결과는 조직 관리자들이 효과적인 지휘 전략을 수립하는데 기초 자료가 될 것으로 기대된다.

본 논문은 목회자 사모들의 정신건강과 영적 안녕감 간의 관계를 파악하기 위해 부정적 정신건강 요소인 우울과 긍정적 정신건강인 심리적 안녕감이 영적 안녕감에 미치는 영향을 분석하였다. 그 결과 우울은 영적 안녕감과 부적 관계를, 심리적 안녕감은 영적 안녕감과 정적 관계가 있었고, 우울보다 심리적 안녕감이 영적안녕감에 더 많은 영향을 주는 것을 알 수 있다. 우울과 심리적 안녕감의 하위요인들이 영적안녕감에 미치는 영향도 분석하였다

This study aims to explore science inquiry teaching efficacy that middle school science teachers implementing science practice-based teaching for one year recognized as necessary for teaching science through science practice. Examining interview data in this study, science inquiry teaching efficacy was identified in both planning and implementing in the areas of managing efficacy, instructional strategy efficacy, and content knowledge efficacy. In planning science inquiry instruction, there is science curriculum management efficacy under managing efficacy. There are the efficacy of outlining science inquiry lesson, efficacy of organizing science practice, efficacy of questioning for science practice, and efficacy of understanding student science practice under instructional strategy efficacy. Under the content knowledge efficacy are contents and science practice understanding efficacy and core ideas efficacy. In implementing science inquiry instruction, managing efficacy includes science practice time management efficacy and science practice classroom culture efficacy. Instructional strategy efficacy includes efficacy of motivating student science practice, efficacy of responding to student science practice, efficacy of stimulating student active thinking, efficacy of student active engagement in argumentation, efficacy of evaluating student participation. No content knowledge efficacy have been identified in implementing science inquiry instruction.

본 논문에서는 전자계의 시간 변화 파형을 측정하기 위한 모노폴 안테나의 감도 특성을 개선하기 위해 리액턴스 소자를 안테나에 직렬 또는 병렬 연결한 경우의 감도 특성에 관하여 검토하고 있다. 이론 해석의 결과, 리액턴스 소자를 병렬로 연결할 경우에는 장하 리액턴스의 갑이 무한대일 때 감도 특성이 가장 양호하였으며, 직렬로 연결한 경우에는 최대의 감도 특성을 갖는 리액턴스의 값이 존재한다는 것을 알 수 있었다.

부분압 분석 장비의 감도 측정 시스템을 설계 제작하였다. 이 시스템을 이용하여 부분압측정기기로 많이 쓰이는 Quadrupole Mass Spectrometer의 N2, O2, Ar, CO, H2에 대한 감도를 10-4∼10-8torr 영역에서 측정하여 감도의 압력 의존성을 보고 검출 방식, Emission current, Secondary Electron Multiplier 전압 등이 감도에 미치는 영향도 측정하였다. 실험 결과 기체 종류에 따라서는 물론 사용조건에 따라서도 감도의 절대값 변화 및 압력 의존성 변화가 아주 심한 것을 알 수 있었다. 따라서 Quadrupole Mass Spectrometer를 정량적인 측정에 이용하기 위해서는 이에 대한 감도 측정 및 특정조사가 반드시 선행되어야 한다.

In recent years, the VR-interactive action contents industry, which utilizes five senses of human bodies, has continued to grow through areas such as games, tourism, movies, performances and exhibitions, but it has reached to breaking point by unrealistic visual elements. Therefore, the purpose of this study is to analyze the effect of each evaluation factor based on visual immersion of interactive type of VR action contents to overcome the limitations. For this study, firstly, prior research is reviewed. Secondly, the evaluation factors of visual immersion of interactive type of VR action contents and hypothesis are to be derived. Research finding is that there is no difference to recognize proximity, three-dimensionality, visibility and immersion by gender. Also, in order to influence visual immersion, it is important that 3D modeling of characters and objects must be sophisticated to be fit in with their surroundings and lighting. This makes user to be confused where they are actually in.

The purpose of this study was to investigate whether there were difference between gender of engineering students in terms of academic achievement, self-efficacy and engineering self-efficacy. A total of 387 engineering students (male=284, female=103) completed the self-efficacy and engineering self-efficacy test. And students self-reported their grade point average(GPA) in their former semester. The results of t-test with gender about academic achievement indicated that there were not differences in academic achievement between gender. The results of MANOVA with grades indicated that there were differences in self-efficacy and engineering self-efficacy between gender. Male students scored significantly higher than female students in self-efficacy, and engineering self-efficacy.

The purpose of this study is to confirm the effect of the young generation's Fairness perception on the hopelessness at the present time when the hopelessness of the future that young generation is experiencing is growing with social interest. This study examined the mediating effects of the perceived control and moderating effect self-esteem between the fairness perception and the hopelessness of the young generation. For this purpose, the self-reporting data of 313 young people in their 20s and 30s were collected. The results were as follows: First, fairness awareness was positively correlated with perceived control and self-esteem, and the hopelessness was negatively correlated with fairness awareness, perceive control and self-esteem. Second, perceived control mediated between fairness perception and the hopelessness, Third, self-esteem moderated the relationship between the fairness perception and the hopelessness. The high self-esteem group showed little change in hopelessness due to fairness perception while the low self-esteem group showed a big change in hopelessness due to fairness perception, which means that high self-esteem plays a role in alleviating hopelessness when fairness perception is low. The results of this study can be used as basic data to plan ways to improve mental health and quality of life.

An efficient algorithm for inverting static-shifted magnetotelluric (MT) data has been proposed to produce a three-dimensional (3D) resistivity model. In the Gauss-Newton approach, computational costs associated with construction of a full sensitivity matrix usually make 3D MT inversion impractical. This computational difficulty may be overcome by using approximate sensitivities. We use four kinds of sensitivities in particular orders in the inversion process. These sensitivities are computed 1) analytically for an initial, homogeneous earth, 2) exactly for a current model, 3) approximately by the Broyden method, and 4) approximately using the previous adjoint fields. Inversion experiments with static-shifted synthetic and field MT data indicate that inversion results are highly dependent on characteristics of data and thus applying various combinations of sensitivities is helpful in obtaining a good image of the subsurface structure with reasonable computation time.
