This study was conducted to identify the correlation between the school-life stress, depression and college adjustment of dormitory residents, in order to provide the basic data needed to establish a strategy to improve the adjustment of college students. The subjects were 210 students in Korea. The data were collected using a self-report questionnaire from September 13 to 19, 2014, and analyzed by frequency, t-test, ANOVA and Pearson's correlation using the SPSS Win 21 program. The school-life stress, depression and college adjustment of the students residing in the dormitory on a 5-point scale were 2.43, 1.88 and 3.81, respectively. School-life stress had a significant positive correlation with depression (r=.639, p<.001) and significant negative correlation with college adjustment (r=-.709, p<.001). Depression had a significant negative correlation with college adjustment (r=-.788, p<.001). Those students with a higher school-life stress showed higher levels of depression and lower levels of college adjustment. Those students with a higher level of depression showed a lower level of college adjustment. Therefore, it is necessary to develop and test a suitable program in order to understand the differences between psychological adjustment based on gender, and to decrease school-life stress and depression and increase college adjustment.

The purpose of this study was to investigate the correlations between ADHD, depression, anxiety, suicide risk and suicide risk of university freshmen, and to investigate factors affecting suicide risk of university freshmen. As a result, the correlation between suicide risk and ADHD, depression, and anxiety were statistically significant. The correlation between suicide risk and ADHD (r=-.411) was moderately negative, while depression (r=-.594) and anxiety (r=-.563) were high negative correlations. According to the logistic regression analysis, the significant factors affecting suicide risk of college freshmen were ADHD, depression, and anxiety. In the abnormal group of variables, ADHD (OR=3.17; 95% CI 1.36-7.38), depression (OR=10.80; 95% CI 4.32-27.02) and anxiety (OR=3.39; 95% CI 1.55-7.41) were identified as influencing factors. As such, suicide risk groups of college freshmen are highly associated with ADHD, depression, and anxiety. Therefore, personal counseling and regular psychological tests of college freshmen will be provided to the high-risk suicide program to help students' psychological stability and adjustment to school life.

This study conducted a sediment culture experiment to investigate the effects of sediment oxygen demand (SOD) and environmental factors on sediment and water quality. We installed a leaching tank in the laboratory, cultured it for 20 days, and analyzed the relationship between P and Fe in the sediment. As a result, the dissolved oxygen of the water layer decreased with time, while the oxidation-reduction potential of the sediment progressed in the negative direction to form an anaerobic reducing environment. The SOD was measured to be 0.05 mg/g at the initial stage of cultivation and increased to 0.09 mg/g on the 20th day, indicating the tendency of increasing consumption of oxygen by the sediment. The change is likely to have caused by oxygen consumption from biological-SOD, which is the decomposition of organic matter accumulated on the sediment surface due to the increase of chl-a, and chemical-SOD consumed when the metal-reducing product produced by the reduction reaction is reoxidized. The correlation between SOD and causality for sediment-extracted sediments was positive for Ex-P and Org-P and negative for Fe-P. The analysis of the microbial community in the sediment on the 20th day showed that anaerobic iron-reducing bacteria (FeRB) were the dominant species. Therefore, when the phosphate bonded to the iron oxide is separated by the reduction reaction, the phosphate is eluted into the water to increase the primary productivity. The reduced substance is reoxidized and contributes to the oxygen consumption of the sediment. The results of this study would be useful as the reference information to improve oxygen resin.

This is an investigative study to identify the degree of post-traumatic stress and anxiety of nurses in relation to the COVID-19 pandemic, and to analyze the relationship with the nurse's belief in behavior and control that affects nursing intentions to determine their impact on the belief in behavior. The subjects of this study were nurses with experience of directly nursing COVID-19 patients at medical institutions located in Gyeonggi-do. The SPSS 22.0 version was used for the descriptive analysis, independent t-test, one-way ANOVA, Pearson's correlation coefficients and multiple regression. Post-traumatic stress of the participants in this study was found to be 24.20±20.58, anxiety 48.31±6.61, behavior beliefs -1.00±17.12, and control beliefs 3.41±11.66. According to this study, the belief in conduct is negatively correlated with post-traumatic stress (r=-4.71, p<).001) and showed a significant negative correlation with anxiety (r=-2.248, p<.05). There was no significant correlation with control beliefs (p>.05). Based on the results of this study, it is proposed to develop an appropriate psychological arbitration program for mediating post-traumatic stress in order to promote the nurse's behavior beliefs.

본 연구에서는 한국 주식시장에서의 주가결정과정에 비합리적인 요소가 내포되어 있는지의 여부를 정가하기 위하여 Fama-French(1988)의 검증방법론을 이용하여 한국종합주가지수, 자본금규모별 주가지수, 산업 별 주가지수, 그리고 한경다우지수 등을 대상으로 실증분석을 실시하였다. 주가의 평균회귀과정(mean-reverting process)이 주식수익률들간의 음의 자기상관관계를 유발한다는 관찰에서 출발한 본 연구는 미국에서의 실증분석 결과와는 판이하게 주식수익률들이 2년까지의 수익률계산기간(return horizon)에서 지속적인 양의 자기 상관을 갖고 있음을 발견하였다. 본 연구에서 발견된 실증분식결과는 대상주가지수에 관계없이 일관성있는 패턴을 유지하고 있는데, 이는 Fama-French(1988)의 결과에 정면으로 배치된다. 따라서 본 연구에서의 실증분석 결과는 우리나라 주식시장의 경우 주가에 비합리적인 평균회귀요소(mean-reverting components)가 포함되어 있다는 가설을 지지하지 않는 것으로 해석 될 수 있을 것이다. 물론, 이것이 반드시 우리 주식 시장에서의 주가결정이 합리적으로 이루어진다는 것을 의미하지는 않으며, 단지 본 연구에서 주장되고 있는 것은 우리 주식시장에서의 주가결정과정을 랜덤웍과 평균회귀과정의 합성 혹은 평균회귀과정 그 자체로 모형화하려는 시도는 실증적 증거에 뿌리를 두고 있지 않다는

다양한 소프트웨어 척도들이 절차적 패러다임에서 유용하다는 것이 밝혀졌고 객체지향 패러다임에 대해서도 많은 설계 척도들이 언어 독립적으로 제안되었다. 언어 독립적인 척도로부터 특정 프로그램밍 언어에 대한 척도를 명확하게 하는 것이 중요한데도 불구하고 Java 언어에 대한 척도는 거의 제안되지 않고 있는 형편이다. 따라서 본 논문에서는 Briand가 제안한 속성을 만족하는 척도들과 Java 언어의 특징인 내부 클래스를 반영한 척도와 크기 척도 등 13개의 척도를 Java 프로그램에 적용하여 척도들 사이의 관계를 분석하였다. 클래스의 크기와 메소드 호출 빈도, 응집도, 자식 클래스의 수, 내부 클래스와 상소 계층의 깊이가 주요 인자라는 것을 보여준다. 또한 응집도가 다른 척도들과 음의 관계를 가진다는 것이 발견되었다. 보다 적은 척도를 가지고 인자를 설명할 수 있는 회귀식을 도출하고 교차검증을 실시하였다.
