This study examined the relationship between the death perceptions and attitudes of the severely diseased persons in hospice facilities based on their general characteristics. The surveys were conducted from March 10 to July 31, 2013 on 149 patients at hospice facilities in ${\bigcirc}$ city, Gyeonggi-do. The data was analyzed by the SPSS WIN 18.0. First, positive death attitudes showed significant differences according to the patients' general characteristics (F=6.218, p<.001). Second, the patients' death attitudes by their death perceptions showed meaningful results (F=6.634, p<.001). Third, the death attitudes revealed a positive relation with hospice use (r=.496, p<.001). Overall, patients, who have positive death perceptions and attitudes, have high expectations for hospice use and these results support for welfare policies to encourage hospice use of severely diseased persons.

This paper proposes a novel method for deriving the Fourier transform pairs of high order pulses given in a generalized form. Primarily, modifying the PRS system model, we establish a new model which simplifies the process of Fourier analysis of the n-th order pulse signal, resulting in a representative relationship. In succession, we present the Frame Formula which plays a role of substituent for the parameters in table look-up procedures. Each look-up table contains all the parameters needed to obtain the Fourier transform of the corresponding pulse of any order. Regarding the amount of calculations and the complexity of procedures required to derive the transforms of pulse signals, analytically or numerically, this method is more compact and timesaving than conventional methods. When pulse has a much narrow width of equivalently higher the order of several pulses, the method presented here acts to the best of its true merit.

The purpose of this study is to find the relation between the detailed categories of the self-efficacy of workers in the field of railroad signaling and the detailed categories of their fatigue in the use of analysis of moment structure(AMOS) model. A self-administered questionnaire survey of workers in the field of railroad signaling had been conducted and a total of 341 copies were analyzed. This study had the assumption that their general self-efficacy and social self-efficacy would negatively influence their physical fatigue and mental fatigue. As a result, their general self-efficacy negatively influenced their physical fatigue and mental fatigue, whereas their social self-efficacy didn't influence their physical fatigue and mental fatigue. Therefore, it is possible to reduce the fatigue of the study subjects by enhancing corporate support to increase their general self-efficacy.

식생의 성장은 수문순환과 밀접히 연관되어 있으며 특히 강수량은 식생의 연간변동성의 주된 요인이다. 하지만 국내의 경우 이러한 식생과 강수량과의 관계를 알아보기 위한 정량적인 접근은 시도되지 않은 실정이다. 순일차생산량(NPP)은 광합성으로부터 생성된 유기물질에서 성장에 필요한 호흡량을 뺀 것이며, 이는 식생량을 산정할 때 주로 이용된다. 본 연구에서는 우리나라 전역의 50 지역의 5년간의 NPP와 연강수량이 분석에 사용되었다. 비록 자료기간이 관계를 정립하기에는 다소 부족하며 NPP자료 자체의 불확실성이 내포되어 있지만 각 지점별 NPP와 강수량과의 상관성이 매우 높은 지역들이 있는 것으로( ��0.6) 나타났다. 하지만 모든 지역의 자료를 동시에 고려하였을 경우에는 결정계수가 크게 감소하였다($R^2$=0.310). 추가적으로 강우이용효율과 연강수량의 관계를 분석하였으나 결정계수가 0.022로 기존의 문헌과는 달리 이들 사이에 뚜렷한 관계가 나타나지는 않았다. 본 연구를 통하여 확인된 사실은 우리나라의 식생과 강수량 관계에서는 우리나라 전역을 전반적으로 설명할 수 있는 일반적인 선형 관계를 찾기는 힘들다는 것이며, 다만 지역별로 살펴볼 경우 식생-강수량 관계가 비교적 잘 맞는 지역들이 다수 존재한다는 것이다. 따라서 우리나라를 대상으로 한 생태적요소가 고려된 수문모형을 개발할 경우 지역적 특성들이 모형 구조에 반영되어야 할 것이다.

This paper describes the Korean Question answering system using the syntactic-relation information d verbs to overcome lack of reliable knowledge and linguistic resources. The syntactic-relation information consists d the original form d a verb, usual usage pattern, semantic category of each dependent noun, synonym verbs and passive verbs. We use the syntactic-relation information to parse sentences or phrases with usual usage pattern of the verb and semantic conditions of dependent components on the verb. We also use that information to parse answer candidate sentences, and find an answer from questioned case slot. Our experiments that usage of the syntactic-relation information of verbs to mm lack of reliable knowledge and linguistic resources can be utilized efficiently for the Korean question answering system.

Only a few studies investigated the relationship between exchange structure and solidarity in online communities and even reported conflicting results. This study attempts to shed lights on this relationship by introducing a moderating variable, i.e., exchange benefits, based on the social exchange theory. Also, distributed knowledge is considered as a determinant of exchange structure. The results of a field study from 380 online communities show that both direct and generalized exchange structures have positive effects on community solidarity, but their effects vary depending on the level of exchange benefits. When exchange benefits are high, generalized exchange influences community solidarity more than direct exchange does, whereas at a low level of benefits there are no significant differences between the two exchange structures. Also distributed knowledge turns out to be a significant influencer of generalized exchange.

The purpose of this study is to verify the general characteristics in the previous studies and the magnitude of the correlation between the learner's satisfaction and the academic achievement in the education and training program. To do this, we searched relevant literature from 2000 to 2016, and conducted a systematic review of the literature on the final 31 studies through the selection criteria and quality evaluation. Among them, 27 meta-analysis of the literature was conducted. The finding of the study were as follows. First, a total of 31 studies were conducted from 2000 to 2016, and more than half of them(16) were conducted for the last 4 years(2009~2012). In terms of education and training students, there are 18 college students, 9 workers, and 4 elementary students in order of study. In terms of methods, 15 collective education, 14 distance education, 2 blended education. In terms of learner's participation, 22 the general participation, 9 the active participation. Second, as a result of the meta-analysis, the magnitude of the correlation between satisfaction and achievement was moderate(ZCOR=.297, 95%: CI .210~.383). Third, as a result of verifying the difference in the magnitude of the correlation effect between satisfaction and achievement according to the characteristics of the education and training program, there was no difference between the groups in the student object and education method, but there was a difference in the magnitude of the correlation effect depending on the participant type(Q=15.40, df=1, p<.0001). The active participation showed a correlation effect size larger(ZCOR=.588, 95%: CI .422~.754). The effect size of the general participation was lower than the median(ZCOR=.211, 95%: CI .12 ~.300).

The purpose of this study is to examine the relationships between teacher's efficacy and job stress and the effects of educare center teacher's teaching efficacy on job stress. The subjects of this study were 200 teachers at the public, private, or home child-care centers in Pyeongtaek, Songtan and Osan. To analyze the general characteristics of subjects, frequency analysis and descriptives, ANOVA and correlation analysis, and multiple regression were used. The results of this study were as follows: First, educare center teacher's teaching efficacy level was a little higher than the average. The mean score of general belief of teaching efficacy was a little higher than the personal belief of teaching efficacy. Second, educare center teacher's job stress level show to be lower than average. Job related stress is the highest. Next is, the child related stress, personal related stress. Third, teaching efficacy significantly influenced on the job stress. The result indicated the higher educare center teacher's belief of efficacy was, the lower the job stress was. While general teaching efficacy was not associated with teaching efficacy, personal teaching efficacy was significantly related to teaching efficacy. The result of analyzing the effects of educare center teacher's teaching efficacy on job stress showed personal teaching efficacy had a strong influence on job stress. In detail, there was a significant negative correlation between personal teaching efficacy and job stress. Among the general factors such as the level of education, monthly income, work hours had significant influence on job stress. Therefore, the higher the level of education, the less monthly income, the longer work hours, it appeared that educare center teacher's job stress is higher.

The purpose of this study is to understand the effects of ego-resilience, empathic ability of preliminary broadcasters on communication ability and to explore what university should do. The subjects of the study analyzed the relationship between self-resilience, empathic ability and communication ability among 333 preliminary broadcasters in the journal and broadcasting, media related departments of five universities in Busan. As a result of the research analysis, first, the preliminary broadcasters had the highest empathic ability, followed by communication ability and ego-resilience. Second, ego resilience according to the general characteristics of preliminary broadcasters was significantly different according to gender, major satisfaction, and club activities. There were significant differences according to satisfaction and club activities. Third, the correlation between ego resilience, empathic ability, and communication ability of preliminary broadcasters has a significant static correlation, and the correlation between empathic ability and communication ability is the highest. Fourth, the factors influencing communication ability were empathic ability, ego resilience, and gender. It will be meaningful as a study that the factors influencing communication ability related to preliminary broadcasters are empathic and ego resilience. Therefore, it is necessary to prepare a plan such as opening a curriculum to improve the communication ability of preliminary broadcasters.
