본 연구는 동영상을 활용하여 자아성찰을 통한 자율실습 후 기본간호 수행능력 및 수행자신감, 학업적 자기효능감, 실습만족도에 미치는 효과를 규명하기 위해 비동등성 대조군사후설계 유사실험 연구를 수행하였다. 연구대상은 G지역 일개대학 간호학과 2학년을 대상으로 하였으며, 실험군 57명, 대조군 56명이었다. 자료수집은 2017년 4월1일부터 6월 14일까지였다. 자료는 SPSS 22.0 Program을 이용하여 동질성 검정은 ${\chi}^2$ test, t-test 및 Fisher's exact test로 분석하였고, 변수에 대한 집단 간의 사전동질성 검정은 Independent-test를 시행하였다. 연구결과 기본간호 수행능력 및 수행자신감, 학업적 자기효능감(t=15.304, p<.001), 실습만족도(t=15.304, p<.001) 모두 실험군이 대조군보다 점수가 향상되었을 뿐만 아니라 통계학적으로 유의한 차이를 보였다. 결론적으로 기본간호 자율실습 시 동영상을 촬영한 후 자아성찰을 통한 실습방법은 자율실습 참여에 긍정적인 효과를 초래하였을 뿐만 아니라 학습자들의 학습동기를 높여 적극적이고 능동적인 실습참여에 기여할 수 있을 것으로 예측된다. 따라서 본 연구결과를 토대로 기본간호 술기능력을 향상시키기 위해 보다 다양한 실습에 적용해볼 것을 제안한다.

반도체와 전자부품의 코팅제로 사용되는, 특히 LCD와 PDP 커넥터주위의 보호를 위해 사용되는 폴리실록산(시편)의 흐름성(flow) 및 퍼짐성(self-leveling)을 측정할 수 있는 시험 장치가 고안되었고, 점도가 각기 다른 실록산 폴리머 견본들을 이용하여 고안된 시험장치를 시험하였다. 이 장치를 사용하여 시편의 흐름성 및 퍼짐성을 측정한 결과, 이 장치가 점도를 통해 흐름성 및 퍼짐성을 예측하던 것을 대신 할 수 있다고 판단되었다. 특히, 흐름성이 적절히 조절되어야만 하는 LCD, PDP 및 반도체 커넥션 보호 코팅제의 특성 평가에 유용하게 활용될 것으로 기대된다.

Purpose: This study was conducted to investigate factors affecting the dementia screening test based on the health belief model. Methods: The survey was conducted with structured questionnaires assessing the knowledge of dementia, health beliefs, self-efficacy and cue to action for dementia screening. Study participants were 156 older adults and data from 121 respondents were analyzed. Descriptive statistics, frequency percentage, chi-squared (${\chi}^2$) test, t-test and logistic regression analysis were conducted using SPSS version 23.0. Results: Factors influencing the dementia screening test were found to be gender, self-efficacy on dementia screening, and the presence of family or friends who underwent dementia screening. Older adults who were female (OR=4.92, p=.003), showed an increasing average score of self-efficacy for dementia screening (OR=2.85, p=.002), and had family members or friends who underwent dementia screening (OR=4.60, p=.003) were more likely to receive dementia screening. Conclusion: This study showed that education and programs enhancing self-efficacy associated with the dementia screening test, as well as utilizing the network of family or friends are necessary to increase the rate of dementia screening.

본 논문에서는 저잡음 증폭기 (Low Noise Amplifier, LNA)를 위한 프로그램 가능한 RF (고주파) BIST (Built-In Self-Test) 회로를 제안한다. 개발된 BIST 회로는 온 칩 형태로 DC 측정만을 이용하여 LNA의 RF 변수들을 측정할 수 있다. BIST 회로는 프로그램 가능한 커패시터 뱅크 (programmable capacitor banks)를 가진 test amplifier와 RF 피크 검출기로 구성되어 있다. 이러한 온 칩 회로는 각각 GSM, Bluetooth 및 IEEE802.11g의 응용을 위해 세 가지 주파수 대, 즉 1.8GHz, 2.4GHz 및 5GHz에서 사용할 수 있도록 프로그램 되어있고, LNA가 가지는 RF 사양들, 즉 입력 임피던스 및 전압이득 등을 DC 전압으로 변화시켜주는 역할을 한다.

The primary purpose of this study was to investigate the relation between paternal self-esteem, child-rearing behaviors and child's self-esteem. The secondary purpose was to examine whether there were significant relational differences according to child's sex. 272 dyads consisting of fifth and sixth grade children in elementary school and their measured by the Self-Esteem Inventory (for children), the Self-Esteem Scale (for fathers), and the Iowa Parent Behavior Inventory: Father form. Pearson's r., F-test, and Ducan's multiple range test were used for data analysis. Paternal self-esteem was significantly associated with 'parental involvement', 'reasoning guidance', and 'intimacy'. Paternal self-esteem was positively correlated with girl's self-esteem. Child's self-esteem was positively related to 'parental involvement', 'limit setting', 'responsiveness', 'reasoning guidance' and 'intimacy'. In sex differences, only boy's self-esteem wasn't related to paternal 'limit setting'. Boys' self-esteem was strongly related to 'parental involvement', and girls' self-esteem was strongly related to 'reasoning guidance'.

The solidification crack susceptifility of aluminum alloy weld metal have been evaluated by means of the slef restraint and external restraint cracking test. It has been observed expermently as follows : (1) The manganese is beneficial to decrease the solidification cracking susceptibility. (2) Weld metal containing zirconium is less sensitive to the solidification cracking than the weld metal containing chromium does. (3) The self restraint test method shows the same tendency in results as the external restraint test does.

This research is to investigate the self-weight consolidation settlement and desiccation shrinkage settlement of soft marine dredging clay by performing numerical and experimental works. Large column test were carried out investigate the consolidation settlement considering effect of the self-weight and desiccation shrinkage, and centrifuge model test was also carried out investigate self-weight consolidation settlement. Results of centrifuge model and large column experiments about changes of settlement with time were analyzed by using the numerical technique of explicit finite difference method considering effect of the self-weight and desiccation based on the finite strain consolidation theory. Centrifuge model test results were in relatively good agreements with analyzed results in terms of self-weight consolidation settlement with time. Large column test results showed quite different values from the numerically estimated one, carried by experimental conditions.

The purpose of this study was to investigate the effects of mindfulness meditation programs based on stress management on the perceived stress, self-control, self-esteem and satisfaction with life scale in nursing college students. A quasi-experimental study with a non-equivalent control group pretest-posttest design was used. Participants consisted of an experimental group(n=18) and a control group(n=22). The experimental group received the mindfulness meditation program for 60 minutes a week for 13 sessions. Data were analyzed using descriptive statistics, ${\chi}^2-test$, Fisher's exact test, t-test, Mann-Whitney U test. The results showed there were significant decrease for perceived stress(t=-9.43, p=.025) and improved self-esteem(t=1.98, p=.038) in the experimental compared to group control group. These findings indicate that mindfulness meditation programs is effective to psychological well-being in nursing college students. Therefore this program needs to be considered as a nursing curriculum for students.

The purpose of this study was to investigate the relationship between adolescent's attachment on parent and self-concept. The subjects were 271 students in the second grade of the junior high school in Busan. The Inventory of Parent and Peer Attachment scale(IPPA) and the Self-Concept test were used for collecting data. For the statistical analysis of data, t-test, F-test, Scheffe test, Pearson correlation and Regression were used. The results were as follows : 1. There were significant differences in attachment according to socio-demographic variables(sex, parent's age, parent's education, parent's job, income). 2. There were significant differences in self-concept according to socio-demographic variables(sex, parent's age, parent's education, parent's job, income). 3. Adolescent's attachment on parent was significantly correlated with adolescent's self-concept.
