The purpose of this study was to identify factors that influence school adjustment in male high school students. The participants were 569 male high school students (1th and 2nd grade) in A city. We analyzed quality of life, family strength, self-resilience, and school adjustment of subjects. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients and multiple regression with the SAS program. The result of this study was that school adjustment was significantly different by school achievement, financial abilities, job of father, scholarship of mother, smoking and drinking alcohol, suicidal ideation and suicide attempts. The school achievement, suicidal ideation, and other quality of life, family strength, self-residence explained 61.4% of school adjustment. Based on the results, if we develop the program which focusing on quality of life, family strength, self-resilience, we could make a meaningful improvement of school adjustment of high school student.

The purpose of this study was to compare perception of importance and performance of the preceptor's role in clinical education between nursing students and preceptor nurses. Data were collected using a questionaire from 339 nursing students and 52 preceptor nurses. The perceived importance of preceptor's role was higher than the performance. Also, the perceived importance of the preceptor's role was correlated with the performance of nursing students only. It is essential to consider importance and performance of the preceptor's role in developing clinical education program for nursing students. These findings suggest that the guideline for role model and the strategies to increase performance of the preceptor's role are needed.

The purpose of this study is to investigate the levels of depression of the college students, and correlation of depression and anxiety, unemployment stress, self-esteem, and finally to explore the moderating effect of resilience between those variables. The participants of the survey were 298 college students. The data were analyzed with t-test, ANOVA test, Pearson correlation coefficient, and moderated multiple regression by SPSS Win 18.0. The major findings were as follow; students appear to have more depression when they are female, in 1st, 2nd, 4th grades than 3rd grade, and in a low economical status. Students' depression had a positive correlation with anxiety and unemployment stress, and had a negative correlation with self-esteem, resilience. In moderated multiple regression analysis, self-esteem and anxiety were influenced by resilience such as self-control ability. Therefore, the intervention strategies for decreasing depression of college students should include development of resilience, especially self-control ability in specific, besides control of the anxiety and unemployment stress.

In this research, in order to investigate the principles for the development of mathematics textbook for decision-making based on storytelling, we conceptualized the educational meaning of decision-making and specified the principles and the methods for the textbook based on decision-making. We illustrated the principles and the methods by the cases from the model textbook for the conditional probability that we have developed. We discussed the implication for the future development and implementation of mathematics textbook for decision-making based on storytelling.

This article described the development of transparent antimicrobial oxo-biodegradable (AOB) film with the function of enhanced freshness of food by employing oxo-biodegradable masterbatch (MB) and antimicrobial MB together with organic metal salt, organic acid, or unsaturated fatty acid. Antibacterial test of the AOB film with the different contents of the antimicrobial MB resulted in the significant freshness extension of plum. Tensile strength and elongation rate of the AOB films before UV treatment were similar to those of polyethylene films used as control. The reduced mechanical properties of AOB film after UV treatment (340 nm) suggested that the AOB film could be degraded by oxo biodegradation. The developed AOB films can effectively prevent decomposition of food by providing antibacterial function and preserving freshness.

The purpose of this study is to analyze the 'Framework for Information Literacy for Higher Education' filed by the ACRL (Association of College and Research Libraries) Board on February 2, 2015 and adopted on January 11, 2016. Six concepts central to information literacy in Framework and four main theories or models (i.e., threshold concepts, metaliteracy, Backward Design, and Liminal Space) underpinning the Framework were analyzed. The Framework provides conceptual or descriptive approach. In addition, the Framework is not designed to be implemented in a single information literacy session in a student's academic career. Instead, it is intended to be systematically integrated into the student's academic program at variety of levels. This study recommends curricular development and assessment methods supporting Framework as a further study.

목적: 의료수준의 발전과 더불어 대중들의 건강요구와 건강증진에 대한 기대 수준도 점점 높아지므로 간호사는 대상자의 요구를 이해하고 양질의 간호를 제공하여 환자의 건강상태를 바람직한 방향으로 변화시켜야 한다. 따라서 이 연구는 환자가 인지한 간호에 대한 경험과 대상자가 경험한 간호에 대한 만족도를 파악하고, 그 관계를 규명함으로써 환자 간호의 질향상과 간호 만족도 향상을 위한 기초 자료를 제공하고자 한다. 연구방법: 본 연구는 일 종합병원의 127명의 입원 환자가 간호 경험정도와 제공받은 간호에 대한 환자 만족도 정도를 규명하기 위한 서술적 상관관계 연구이다. 연구결과: 첫째, 입원환자의 간호 행위에 대한 간호 지각도의 정도는 각 항목별 비교 분석한 결과 신체적 간호행위에 대한 지각도가 평균평점은 2.74로 가장 높았으며, 또한 환자가 지각한 간호행위에 대한 만족도는 기술-전문적 간호행위(M= 3.55)의 만족도가 가장 높았다. 둘째, 일반적 제특성과 전체 간호행위의 지각도와 차이가 있는지 분석한 결과 연령(p< 0.1)에 따라 유의한 차가 있는 것으로 나타났다. 즉 연령이 높을수록 간호행위에 대한 지각도가 높게 나타났다. 그리고, 간호행위에 대 한 지각도의 하부영역 분류중 신체적간호행위에 대한 지각도는 입원과(p< 0.05)에 따라 유의한 차가 있는 것으로 보였다. 또한 일반적 제특성과 전체 간호행위의 만족도와의 관계에서는 입원과(p< 0.05)에 따라 유의한 차가 있었다. 일반외과 환자가 내과 환자보다 만족도가 높은 것으로 나타났다. 셋째, 입원환자의 간호 행위에 대한 환자의 지각도와 만족도간의 관계(r= 0.39, p= 0.00)는 서로 상관성이 있는 것으로 나타났다. 결론: 본 연구의 대상은 1개 종합병원에 국한된 것이므로 연구결과를 일반화 할 때는 신중을 기해야 한다. 연구결과에서 보여주듯이 정신적 간호행위가 가장낮은 지각도로 나타났듯이 간호사는 환자들의 정신적 지지의 간호가 잘 이루어 지도록 노력해야 할 것이며, 또한 교육적 간호행위의 만족도가 가장 낮게 나타났으므로 보다 더 환자와 간호사간의 정보교환이 잘 이루어지도록 해야 한다. 연구결과를 기초로 하여 전 진료과 병동으로 확대 반복 연구를 제언하며, 환자의 간호 만족도를 향상시키기 위해 전문적 지식 및 긍정적 의사표현등을 포괄하여 간호사의 적극적 간호행위가 수행되어야 할 필요가 있다.

This study attempts to find out the characteristics of digital currency and currency transformation through the analytical descriptions of the literature. In the early days of the emergence of new currency, market-oriented autonomous monetary adjustment was made along with various attempts by the private sector, and then government-centered central currency management and coordination were made for the national monopoly of profits and power. Digital currency can be seen as the emergence of a new form of money that will bring about paradigm changes. CBDC can be divided into direct and indirect types. CBDC is expected to require a strategic approach by the government or firm as it will bring about changes in the ecosystem of related industries. Libra is a stablecoin designed to minimize price fluctuations, and if it succeeds in commercializing it, it is expected to bring about revolutionary changes in the financial industry around the world.

In this paper, a clock and data recovery (CDR) circuit for a serial link with a half rate 4x oversampling phase and frequency detector structure without a reference clock is described. The phase detector (PD) and frequency detector (FD)are designed by 4X oversampling method. The PD, which uses bang-bang method, finds the phase error by generating four up/down signal and the FD, which uses the rotational method, finds the frequency error by generating up/down signal made by the PD output. And the six signals of the PD and the FD control an amount of current that flows through the charge pump. The VCO composed of four differential buffer stages generates eight differential clocks. Proposed circuit is designed using the 0.18um CMOS technology and operating voltage is 1.8V. With a 4X oversampling PD and FD technique, tracking range of 24% at 3.125Gbps is achieved.

In this paper, an integrated optical, evanescent-wave biosensor utilizing a multimode interferometer based on a Si₃N₄ rib-optical waveguide consisting of the Si/SiO₂/Si₃N₄/SiO₂ stacked structure was described. The theoretical background of the multimode interferometer was reviewed, and the structure and design process were presented through numerical computational analysis. We analyzed how the dimension (length, width) of the multimode interferometer affected the sensor performance. It has been confirmed through computational analysis that the changes in the refractive index of an analyte greatly affect the mode pattern formation position and output optical power of a multimode interferometer, and proved that this principle could be applied to integrated-optic biosensor.
