This study investigated predictors of the behavior related to particulate matter in nursing students. The participants in this descriptive study were 186 nursing students at K university in G city from May 1 to 14 in 2018. Collected data were analyzed by t-test, one-way ANOVA, Pearson's correlation coefficient, and multiple linear regression using SPSS WIN 18.0 program. The level of knowledge(10.6/15), attitude(59.94/75) and behavior(42.56/60) were relatively high. The significant predictors of the behavior were attitude(β=.591, p<.001), smoking(β=-.134, p=.049) and respiratory disease(β=.133, p=.025), and explained 40.1% of it. Educational programs to enhance nursing students' health promoting behaviors against particulate matter must be focused on attitude change.

지금까지 수행되었던 원자력발전소의 확률론적 안전성 평가 (Probabilistic Safety Assessment; PSA) 결과, 노심손상 빈도의 30% - 70%가 인간행위와 관련이 있는 것으로 밝혀져 PSA에서 인간행위를 적절히 다루는 것은 매우 중요하다. 특히 원자력발전소의 정지운전인 경우에는 자동으로 작동하는 계통이 거의 없어 고장수목(fault tree)과 사건수목(event tree)의 모델링에 많은 운전인 행위가 포함되기 때문에 노심손상 빈도와 관련이 있는 인간행위는 전출력 운전(full power operation)에 대한 PSA 결과의 경우보다 많은 것으로 나타났다. PSA에서 인간신뢰도분석(human reliability analysis)은 PSA의 논리구조인 고장수목과 사건수목에 모델링될 인간행위를 파악하고 정량화하는 것이다. 현재 인간신뢰도분석은 인간행위에 대한 데이타의 부족과 인간행위 자체의 다변성(variability)으로 인해 분석에 어려움이 있고 분석자의 주관성이 개입될 여지가 많은 실정이며, 이에 따라 분석 결과에는 많은 불확실성을 내포하게 된다.

This study aimed to explore anxiety, risk perception, information literacy, and performance level of infection prevention practices against coronavirus disease (COVID-19) among nursing students during the pandemic. A descriptive online survey was conducted, targeting a total of 224 nursing students from June 8, 2020 to 14, 2020. The collected data were analyzed using descriptive statistics, t-test, analysis of variance, and correlation analysis using SPSS 26.0. The nursing students' level of anxiety was 6.86 out of 10, which was normal. Their information literacy level and performance level of infection prevention practices were 3.50 out of 4 and 4.44 out of 5, respectively, and these scores were considered high. The higher the level of anxiety, risk perception, and information literacy, the higher the level of infection prevention practices. The level of anxiety with respect to infection and risk perception may increase when new types of infectious diseases such as COVID-19 break out. Therefore, it is necessary to promote the accurate understanding of the infectious diseases by providing sufficient information. Accurate understanding of new infectious diseases can reduce the risk of transmission as it encourages people to thoroughly perform infection prevention practices.

전력시장에서의 공정경쟁의 중요성은 새삼 강조의 필요가 없을 만큼 중요한 것이다. 대표적인 전력시장에서의 불공정행위로는 시장지배적 사업자에 의한 시장지배력 행사와 다수 사업자에 의한 부당공동행위, 즉 담합행위를 들 수 있다. 불공정행위의 실제 행위는 시간별 가격과 용량을 입찰하는 과정에서 부당한 이익을 위한 전략적 행위를 행사함으로써 발생한다. 인위적으로 가격을 올리거나 가격이 낮은 발전기의 용량을 축소 입찰함으로써 정상적인 시장가격보다 높은 시장가격이 형성되어 이러한 부당행위의 당사자가 부당을 이익을 얻게 되는 과정이다. 이러한 행위는 상당히 은밀하고 전략적으로 행사되므로 그 적발이 용이하지 않지만 전력시장을 관찰함으로써 징후를 포착하고. 정밀조사를 통하여 부당행위를 적발, 시정하는 지속적인 활동이 필요하다. 본 연구에서는 이러한 부당행위를 적발하기 위한 기본과정으로서 입찰용량의 적정성 판정을 위한 지표개발을 시도하였다. 설비용량과 보수용량을 감안한 입찰가능용량과 실제 입찰한 용량의 상관관계를 분석함으로써 정밀조사 대상이 되는 비정상 입찰행위 식별지표인 용량철회 가능성 감지지표를 개발하였다.

The purpose of this study is to examine the importance of family environment for middle school student's health behavior. In order to do this we collected data through the questioning of 543 male students and 512 female students in 4 Pusan middle schools. The results of this study are summarized as follows. The score on their family cohesion and adaptability was 57.8, 43.5 on the average for male students and 59.8, 44.8 in female students. The score on their family adaptability and cohesion was higher in fema1e students than male students. The score of their Breslow health behavior was 4.20 from a total of 7.00, the total score of health behavior was 131.4 from a total of 176.0 scores. The students had a 43.9 out of 60.0 in personal hygiene and daily habits, 32.8 out of 40.0 for infectious disease preventive behavior, 30.2 out of 40.0 in accident prevention, 24.5 out of 36.0 in mental health. In the cases of males, the score for Breslow health behavior was higher the lower the school grade, the younger the parents, the higher the educational level of parents, the more comfortable the family, and the higher the economic state. There was a statistically significant difference with regard to family cohesion and adaptability. In the cases of females, The total score for health behavior was higher. However, the difference was not significant in other fields. With the multiple regression analysis, the health behavior of middle school student was associated significantly with sex (female students), grade, family cohesion, and adaptability. In Breslow health behavior, scale sex (male students), father's age, family cohesion and the harmony of parents were significant variables. From the results of this study, a good family environment fur middle school students is very important.

The shift in the perspective on learning as participation draws attention to learners' identity work. This manuscript foregrounds the ongoing and fluid processes of identity, and focuses on the structure surrounding learners where identity work occurs and the expression of individual agency. From the perspective of learning as participation, we introduce Holland et al. (1998) identity-in-practice theory, as the theoretical lens that dialectically describes structure, agency and identity. The concepts representing this theory are 'figured world', 'positionality' and 'authoring self'. The figured world is a web of meaning encompassing the continuous construct/reconstruct through human actions and also exerts as the social force that shapes human actions. 'Positionality' on the other hand, means an understanding of one's social position in the world. The notion of 'authoring self', is a dimension that synthesizes the above two concepts, which describes the improvisation of one's self through the orchestration and collaboration of various social voices. Next, we analyzed and described various cases of this theory that we found within the scope of science education. However, due to the nature of this theory, which takes a sociocultural approach, international research studies cannot be simply applied to the Korean context. Therefore, we sought to expand the applicability of this theory as a methodological tool, by discussing the directions in which this theory can be used in a domestic context. It is intended that the introduction of this theory, which emphasizes multi-layered, continuous and cumulative identity work, will be used as a resource to further expand the horizon of science education reform that is required for the times.

In this paper, we develop a dynamic structural model based on a dynamic supergame and measure market power for the Dallas-Forth Worth fluid milk market in the U.S. In particular, we compare the conduct parameter estimates from a static model with that from the dynamic model and illustrate bias in the market-power measure in a static model. And we also analyze the cyclical behavior of firm conduct. We find that the conduct parameter in a static model underestimates true market power if firms' behaviors are posited by a dynamic oligopoly game. We also verify that firm conduct in the Dallas-Forth Worth fluid milk market is countercyclical against demand shocks and expected future cost shocks. Our results indicate that the firms' conduct in the Dallas-Forth Worth fluid milk market is consistent with what dynamic oligopoly models predict. This implies that the firms consider not only the contemporary reactions of the other firms' but also future market competition. Therefore, the measurement of market power requires the specification of fully dynamic pricing relationship.

This study was a descriptive study to identify the effect of health promoting behavior on fatigue and depression and to investigate these levels among nurses. Data were collected from September 19th 2012 to September 25th 2012 by questionnaires from 243 hospital nurses of 3 hospitals in Kyungsang-Bukdo. The data was analyzed using descriptive statistics, t-test, Pearson's correlation coefficients, ANCOVA, and Stepwise multiple regression. The result showed that in health promoting behavior, shift nurses had higher scores than it of non-shift nurses. The health promotion behavior predictors of fatigue were spiritual growth and stress management and the predictors of depression were physical activity and interpersonal relationship. This results suggest that development of professional health promoting program which is strengthened these parts of spiritual growth, stress management, physical activity and interpersonal relationship, is needed.

The purpose of this study was to investigate health concern, health information orientation, e-health literacy and health behavior, and to identify affecting factors of health behavior on elderly women. The subjects consisted of 203 elderly women in the C city. The variables were measured using questionnaires, analyzed using descriptive statistic, t-test, ANOVA, and multiple regression analysis. The health concern, health information orientation and health behavior were not significant difference in 60s and 70s. The e-health literacy was significant difference. Factors influencing health behavior in 60s was health information orientation, and explanation of health behavior is 14.8%. In 70s was living situation, and explanation of health behavior is 6.6%. These results suggest that it is necessary to develop health promotion program to improve health behavior for elderly women, and including health concern, e-health literacy in the information era.
