The purpose of this study was to examine the level of recognition, information acquisition behavior, level of knowledge, level of behaviors to decrease exposure, and education need towards endocrine disruptors of middle and high school students. The data were collected from 180 middle and high school students in Seoul, Incheon, Daejeon, Daegu, Busan and Gwangju. Frequencies, Cronbach's alpha, t tests, analysis of variance, Duncan's multiple range tests, and chi-square tests were carried out by SPSS WINDOWS Version 14.0. The results of this study were as follows. The level of concerns about endocrine disruptors was somewhat low. Many respondents obtained information about endocrine disruptors from TV/radio and school, and wanted to get the information from school and TV/radio. Both the level of knowledge and the level of behaviors to decrease exposure were not particularly high. In addition, they showed high level of education need for endocrine disruptors.

건축물 마감재료의 연소시 발생되는 독성가스는 대형화재로 인한 인명피해의 주된 원인 중의 하나이다. 현행 건축법에서는 건축물마감재료에 대하여 동물의 평균행동정지시간을 측정하는 가스유해성시험을 실시하고 있다. 본 연구는 동물시험이 아닌 NFPA 269에 의한 유효량분율(FED: Fractional effective does)을 이용하여 건축물 마감재의 독성지수를 도출하였다. 현행 가스유해성 평가 방법에서 사용되는 채임버(피검상자)를 이용하여 적외선분광분석 및 산소분석기로 연소가스를 정량 분석하였으며, NFPA269에서 규정하는 FED를 도출하였다. 몇 가지 건축재료에 대한 가스유해성시험의 평균행동정지시간과 FED의 상대적인 비교를 통해 연소가스독성평가를 수행하였다.

컴퓨터교과는 학생들의 일반적인 학업성취 개인차 요인과 더불어 필수 교과가 아니기 때문에 학교 혹은 교사마다 교육하는 내용이 상이하여 학생들이 상급학교로 진학하였을 때 학생들 간의 수준 차가 심화된다. 이러한 다양한 수준차가 있는 학생들을 교사 1인이 한정된 시간 안에 모든 학생들의 수준에 맞추어 지도하는 것은 대단히 어렵다. 또 넓은 컴퓨터실에서는 학생들의 주위가 분산될 우려가 많으므로 학생들의 행동을 수시로 관리할 필요가 있다. 이러한 컴퓨터교과 실습수업 시에는 보다 효과적인 지도방법이 요구된다. 이에 본 연구에서는 컴퓨터교과 실습지도 방법의 장단점을 분석하고, 컴퓨터교과 실습수업 시 널리 사용되는 시범 실습법의 단점을 보완할 수 있는 도우미학생 활용 시범 실습법을 제안하고, 중학교 컴퓨터 정규교과 시간에 적용하여 그 효과를 검증하였다. 도우미학생 활용 시범 실습법이란 교사는 실습내용을 설명하고, 모든 학생들은 교사의 설명과 동시에 실습을 하며, 도우미학생의 실습내용이 빔 프로젝트를 통해 다른 학생들에게 보여짐으로써 교사의 시범을 대신하는 방법을 말한다. 컴퓨터교과는 설명만으로도 실습 가능한 내용이 많아 이러한 지도방법이 가능하다 이 방법은 실습내용을 최소한의 작은 단계로 구분하고, 각 단계별로 교사의 설명과 개별지도, 모든 학생의 실습과 관찰이 동시에 이루어진다. 이 방법은 교사의 행동이 자유로워 설명과 동시에 개별지도가 가능해 개별지도의 확대를 가져올 수 있으며, 학생들에게 보다 많은 즉각적인 피드백을 줄 수 있으며, 학생들의 행동을 수시로 관리할 수 있다는 장점이 있다. 또한 본 연구에서는 검증도구로 'html 태그' 단원 5차시 분량의 과제수행능력평가도구를 개발하여 사용하였다. 검증결과 학업성취 중하수준의 도우미학생 활용 시범 실습으로 수업한 집단은 통제반과 유의미한 차이가 없었으나, 학업성취 중상수준의 도우미학생 활용 시범실습으로 수업한 집단은 통제반에 비해 과제수행능력에 있어서 유의미한 차이를 보였다 이로써 제안한 지도방법의 효과성을 입증하였다.

This study aimed to analyze users' behaviors to use mobile services of academic libraries by indirectly observing users' experiences based on their diaries. Ultimately, this study intended to contribute to the development of mobile services in academic libraries by helping academic libraries understand users and their needs of mobile services. For this, diary method was conducted with 20 students at two academic libraries. These participants should report detailed process and thoughts immediately after using mobile library services at least once a day during a week. Totally 137 diaries were collected. And then this study conducted a content analysis to figure out what information needs they had, whether or not the needs were solved, what menu they selected, and what steps and gaps they got. In addition, on the basis of the findings, this study suggested further steps for improving mobile services at academic libraries.

The purpose of this study was to measure repeated the process of non-suicidal self-injury individuals change in everyday life through the Ecological Momentary Assessment(EMA) daily diary. The study subjects of were 17 adults aged 19 to 29, accessed a link sent by text message on a cell phone and recorded a diary of the day's affects, interpersonal conflicts, self-injury thoughts, and behaviors once a day for two weeks. Using a total of 238 reported entries, the contextual factors of NSSI were examined, and the effects of affects and interpersonal conflicts on NSSI analyzed through a multi-level model. As a result, the negative affects of that day have a significant relation with within subject NSSI behavior and positive affects have a significant relation between subject NSSI behavior. These findings means that overall individuals with low positive affects have a higher risk of self-injury behavior compared to those with higher levles of positive emotions, and an increase in negative emotions on that day within an individual increases the risk of self-injury behavior on that day. In other words, it implies that it is important to manage negative emotions and strengthen overall positive affects for that day in the intervention of emotion-regulation of experienced self-injury individuals. It is meaningful that this study explored NSSI risk factors experienced in daily life through the short-term longitudinal study.

This study conducted a online survey (URL), DM, , E-mail, etc. were used to sample 371 people using the standard convenience sampling method, and 320 valid samples excluding 51 unfaithful respondents were analyzed by applying causality (SEM). First, the hypothesis was adopted with the influence of positive (+) on the emotional response of the human brand's goods value. Second, the hypothesis was adopted that emotional response has a positive (+) effect on consumption behavior. Third, the human brand's goods value has a positive (+) effect on consumption behavior, and the hypothesis was partially adopted. Finally, the indirect effect of emotional response in the relationship between goods value and consumption behavior was found to be statistically significant.

The ammonium salt of nitrosophenylhydroxylamine, called cupferron, has been used not only as the ligand but also as an oxidizing agent for adsorptive catalytic stripping voltammetry (AdCtSV). Cyclic voltammetry was used for elucidating the electrochemical behavior of Os-cupferron complex in 1 mM phosphate buffer. The optimal conditions for osmium analysis were found to be 1 mM phosphate buffer solution (pH 6.0) containing 0.1 mM cupferron at scan rate of 100 mV/s. By using the plot of reduction peak currents of linear scan voltammograms vs. osmium concentration, the detection limit was $1.0{\times}10^{-7}M$.

The purpose of this research is to investigate the experience for behavior intervention and awareness of positive behavior support among beginning special education teachers. For this, 5 special education teachers with less than 2 years of experience participated in this research. One-on-one in-depth interviews were carried out with them, and all interview results were transcribed and analyzed according to the constant comparison method resulted in 4 major themes follows: 'motivation', 'a series of choice', 'regret for intervention' and 'awareness of Positive Behavior Support'. also, 9 sub themes follows: 'educational needs', 'living needs', 'starting intervention', 'process of intervention', 'results of intervention', lack of resources', 'lack of communication', 'new attempts', 'new areas'. During a discussion, requests for behavior intervention and awareness of positive behavior support, which had been drawn in the research results, were discussed, and the limitation of this research was suggested.
