Backgoround: This study aimed to examine the influence of anxiety sensitivity on task performance and physiological stress response, and to assess the effect of depression in this process for the youth population. Methods: We presented participants with an uncontrollable stress situation where they were required to perform mental arithmetic, based on the Montreal Imaging Stress Task (MIST). A total of 29 participants volunteered for this study. They completed the Anxiety Sensitivity Index-Revised and Patient Health Questionnaire-9 to measure their levels of anxiety sensitivity and depression. Two saliva samples, one before and one after the experiment, were collected to assess the change in cortisol levels as an index of physiological stress response. Results: Participants with high anxiety sensitivity showed lower performance on the mental arithmetic tasks and a significant increase in a salivary cortisol level, compared to those with low anxiety sensitivity. Furthermore, cortisol levels showed a remarkable increase where high anxiety sensitivity was coupled with depressed mood. In other hands, the levels of cortisol remained unchanged despite high anxiety sensitivity with low depressed mood. Conclusions: Our results confirm that the interaction between anxiety sensitivity and depression affects participants' task performance and stress response, as measured through behavioral tasks and physiological data with self-report indices. Also, through the physiological data, we examined that those who have a high level of anxiety sensitivity showed maladaptive responses under high stressful situation.

본 연구는 착색렌즈의 광투과율에 따른 명소시 대비감도의 변화를 분석하여 색렌즈를 착용할 때 색상에 따른 적절한 광투과율 기준을 제시하고자 하였다. 정상 시기능을 가진 남자 24명과 여자 13명을 대상으로, 광투과율 80~90%, 60~80%, 43~60%, 30~43%로 착색된 4개의 색렌즈(회색, 갈색, 적색, 녹색)를 순서대로 착용시키고 F.A.C.T. 시표를 이용하여 대비감도 검사를 실시하였다. 검사 결과, 광투과율이 감소될수록 대비감도는 감소되었고, 시감도는 갈색이 가장 높은 것으로 나타났고, 반대로 적색이 가장 낮은 것으로 나타났다. 대비감도 검사결과를 고려한 색상별 권장 광투과율은 갈색, 회색과 녹색 38% 이상, 적색 52% 이상인 것으로 나타났다. 이러한 결과들로 보아 일상생활에서 눈을 보호할 목적으로 색렌즈를 선택할 때 색상과 그 색상에 적절한 광투과율이 고려되어야 한다.

본 연구는 모성취업에 대한 태도에 따른 영아보육의 특성과 어머니의 심리적 복지감 간의 관계를 밝히고자 했다. 취업 중이거나 학교를 다니는 809명의 미국여성을 대상으로 하였으며, 이들의 자녀가 생후 1개월, 6개월, 그리고 15개월일 때 면접조사를 실시하였다. 모성취업에 대해 긍정적인 태도를 가지고 있는 어머니들은 그렇지 않은 어머니에 비해 더 나은 심리적 복지감을 보였으며, 개별 보육보다 시설 보육을, 그리고 더 많은 시간의 보육을 이용하였다. 이들 어머니들은 자녀들이 친인척에 의해 보육되는 경우(relative care)보다 보육시설(child care center)을 이용할 때 더 낮은 수준의 역할 긴장과 높은 수준의 취업결정 만족감을 나타냈다. 보다 부정적 태도를 가진 어머니들은 가정보육(child care home) 이용시 역할긴장 수준이 낮았다. 영아들이 생후 6개월 무렵 두 집단의 어머니 모두 보육시간이 증가함에 따라 취업 결정에 대한 만족도가 낮았으나 15개월에는 부정적 태도의 어머니에게만 이 관계가 유의했다.

본 논문에서는 초등 현직 교사 146명을 대상으로 실시한 소프트웨어 교육 교수효능감 검사지(Software Education Teaching Efficacy Belief Instrument, SE-TEBI) 조사 결과에 따라 교사의 성별, 지역, 경력, 연수 경험 및 시간, SW 교육에 대한 태도와의 상관을 알아보기 위하여 이변량 상관관계 분석을 실시하였다. 그 결과, 소프트웨어 교육 교수효능감(Software Education Teaching Efficacy, SE-TE)에 가장 높은 관련성을 보이는 것은 SW 교육에 대한 태도였으며, 그 다음의 관련성을 보이는 것은 연수 경험 및 시간이었다. 성별은 부적 상관을 보였으며, 지역과 경력은 통계적으로 유의한 상관을 보이지 않았다. 이러한 분석결과는 초등 교사의 SE-TE를 증진시키기 위해서는 SW교육에 대한 긍정적인 태도를 함양할 수 있도록 지속적인 연수 경험을 제공하여야 함을 시사한다.

협력적 필터링은 추천시스템을 구축하는 알고리즘으로 고객별 선호도를 예측하는데 사용되고 있다. 이에 본 연구는 행복감에 영향을 주는 요인인 자존감과 생활여건을 사용하여, 협력적 필터링을 기반으로 한 예측정확도가 높은 모형을 연구하고자 한다. 이를 위해, 자존감과 생활여건에 대한 응답자 간의 유사도 가중치를 각각 계산한 후, 자존감 유사도 가중치를 적용한 모형으로 행복감을 예측하고, 자존감 유사도 가중치에 생활여건 유사도 가중치를 부여한 유사도 가중치를 적용한 모형으로 행복감을 예측하였다. 그 결과 전자의 모형이 후자의 모형보다 예측정확도가 높게 나타났다.

The study aims at analyzing and comparing the effect of video teleconferencing English class with native speakers on class satisfaction and self-efficacy of elementary school students according to grades. Revised Kim's self efficacy and researcher's class satisfaction measuring tools were used for this. Grade 3 got the highest score and grade 6 had the lowest one in class satisfaction. In post-testing on self efficacy, average score was lower than in pre-testing except grade 3. Grade 3 got the highest score and grade 6 had the lowest one in self efficacy. I conclude that as students' grade goes up, their interests decrease in teleconferencing class and native speaker teachers.

The purpose of this study is to study of correlation of characteristcs of bio-medical ethics and self-esteem for undergraduate students and to compare bio-medical ethics perception between health science and non-health science undergraduate students. We investigated bio-medical ethics and self-esteem of 651 undergraduate students including health science students and non-health science students for two weeks in May, 2015. The results of this study showed significant correlation between self-esteem and bio-medical ethics. The higher self-esteem, the more important bio-medical ethics. But it showed no significant difference between two groups in bio-medical ethics about brain death, euthanasia except biotechnology.

This study was conducted to see if a correlation between social support, self-efficacy and quality of life of stroke patients. The study sample was composed of 60 stroke patients who participated in the rehabilitation hospital in G-city and P-city. The survey period for data collection was from August 8.1 - October 10.1, 2017. social support, self-efficacy and quality of life of stroke were administered to those patients. Among the sum of social support, self-efficacy and quality of life marks, a significant correlation was shown statistically at all levels. Through this study, it shows a solid data base is necessary for the improvement of cognitive function in elderly stroke patients.

The Purpose of this study was to examine the relationship social capital between self efficacy, and the elderly in participated employment or not. The subjects were 340 elderly people in K, S, Y City in Jeonnam. The statistics used for data analysi were reliability, frequency, percentage, mean, standard deviation, one way ANOVA, correlation and multiple Regression. The results of this study were as follows ; First, the degree of social capital of the elderly in participated employment was 86.5(median value 81), while the degree of social capital who did not participated was 79.7. And the degrees of elderly's self efficacy was 43.2, those data showed higher than median. while the degree of self efficacy who did not participated was 39.1. Second, The elderly's social capital level in participated employment were significantly according to residence, religion, living state, economic state, frequency of employment, health state, spouse, monthly income, and the elderly's self efficacy level in participated employment were significantly according to social capital, economic state, monthly income, spouse, health state, living state, education, religion, frequency of employment, Third, participation on the employment for elderly' social capital was the highest correlation variable in self efficacy. Fourth, The variables that affect the elderly's social capital level were economic state, health state, spouse, religion, which explained about 13% of the total variance. And the variables that affect elderly's self efficacy level norm, economic state, network, participation, residence, health state, trust, age, spouse, which explained about 34% of the total variance.

The patient radiation dose is different depending on selection of Ion chamber when taking Chest PA which using AEC. In this paper, we studied acquiring the best diagnostic images according to selection of Ion chamber on AEC mode as well as minimizing patient radiation dose. Experimental methods were selection of Ion chamber and change of sensitivity under the same conditions as Chest PA projection. At AEC mode, two upper ion chambers sensors and one lower ion chamber sensor were divided into 7 cases according to selection of on/off. after measuring five times respectively, we obtained average value and calculated exposure dose. Image assessment was done with measured Modulation Transfer Function, Peak Signal to Noise Ratio, Root Mean Square, Signal to Noise Ratio, Contrast to Noise Ratio, Mean to Standard deviation Ratio respectively. In exposure assessment results, selection of two upper chambers was the lowest. In resolution assessment results, image of two upper chambers had the second high spatial frequency at sensitivity at 625(High) was 1.343 lp/mm. RMS value of image selecting two upper chambers was low secondly. SNR, CNR, MSR were the high value secondly. As the sensitivity was increased, radiation dose was decreased but better image could be obtained on image quality. In order to obtain the best medical images while minimizing the dose, usage of two upper ion chambers is considered to be clinically useful at sensitivity 625(High).
