As malicious comments are emerging as social problems, the solution is needed. Many studies have been conducted in various perspectives to understand and prevent malicious comments. In the previous researches, the neutralization of malicious comments has attracted attention as an important factor explaining the malicious comments, but the difference of the degree of neutralization according to the gender has not been rarely considered. In addition, although there are many environmental characteristics that are different from reality in online, research with malicious comments is insufficient. Based on these facts, this study examined moderating effects of gender on relationship between malicious comments and neutralization, and demonstrated the effects of online environmental factors (anonymity, lack of social presence) on malicious comments. As a result of the study, we discovered that the influence of online environmental factors was not found, but neutralization of malicious comments had strong direct influence on malicious comments and moderating effect of gender difference. Based on the results of this study, we discuss academic and practical implications and suggest limitations of research and future research directions.

The 'education panic' is one of the most phenomenal social issue in the current Korean society. The explanations of it until now, however, are rather superficial in a way that they only describe apparent facts and its seriousness, rendering further examination of the psychological motivation of parents who are the protagonist of education panic necessary. With 548 elementary, middle, and highschool students and their parents, the present study has investigated the impact of parents' past experience of 'han', regret, and learning effect regarding education on their parenting style as well as on their children's academic experience. The result revealed that parents' learning effect was related with more affective/autonomous parenting style and reasonable expectation for their children's educational career. On the contrary, parents' 'han' and regret indicated relationship with hostile and controlling parenting style and also with blind intention toward their children's educational career. The negative emotions also seemed to increase their children's academic stress, and lower academic self-efficacy. Such results suggest that the extraordinary education panic in Korea is more than a simple quantitative matter of intensity. The psychological basis and motivation of the people included, a much more quantitative information, should be taken into account.

This study is a descriptive research study to determine the mediating effect of anxiety in the relationship between patient care communication and patient satisfaction among hospitalized patients. Data was collected using self-administered questionnaires from October to December 2021. The collected data were analyzed using descriptive statistics, Pearson's correlation coefficient, and hierarchical multiple regression using the SPSS 24.0 program, and the effectiveness of the mediation effect was tested using the Sobel test. As a result of the study, there was a positive correlation between patient care communication and patient satisfaction, and a negative correlation between patient care communication and anxiety. And there was also a negative correlation between patient satisfaction and anxiety. In the relationship between patient care communication and patient satisfaction, anxiety had a partial mediating effect (z=2.93, p<.001), with an explanatory power of 38.4%. In order to improve patient satisfaction based on the results of this study, it is necessary to develop a program that can improve nurses' patient care communication capabilities and reduce patients' anxiety.

This study was a descriptive research conducted to confirm the mediating effect of self-efficacy in the relationship between caregivers' patient safety knowledge and patient safety management activities. Subjects were 197 caregiver's and data collection was conducted from July 1 to 29, 2022. Data were analyzed using t-test, ANOVA, Scheffe's test, Pearson correlation coefficients and Hierarchical multiple regression analysis using the SPSS 28.0 program. There was a significant positive correlation between caregivers' patient safety knowledge and self-efficacy(r=.653, p<.001), and patient safety knowledge and patient safety management activities(r=.467, p<.001). In addition, the complete mediating effect of self-efficacy was confirmed in the relationship between caregivers' patient safety knowledge and patient safety management activities, and the explanatory power was 46.8%. Therefore, strengthen the patient safety management activities of caregiver's, systematic program development and educational opportunities should be provided to improve self-efficacy.

Longitudinal data are measured repeatedly over time from the same subject, so there is a correlation from the repeated outcomes. Therefore, when analyzing this correlation, both serial correlation and between-subject variation must be considered in longitudinal data analysis. In this paper, we will focus on the marginalized models to estimate the population average effect of covariates among models for analyzing longitudinal binary data. Marginalized models for longitudinal binary data include marginalized random effects models, marginalized transition models, and marginalized transition random effect models, and in this paper, these models are first reviewed, and simulations are conducted using complete data and missing data to compare the performance of the models. When there were missing values in the data, there is a difference in performance depending on the model in which the data was generated. We analyze Korea Health Panel data using marginalized models. The Korean Medical Panel data considers subjective unhealthy responses as response variables as binary variables, compares models with several explanatory variables, and presents the most suitable model.

We have measured the magnetic susceptibilities of a CuF/sub 2/ .center dot. 2H/sub 2/O sample by means of the SQUID(superconducting quantum interference device) at the magnetic fields of 0.5 T and 1 mT, in the temperature range 5-300 K. The sample was found to contain some nonmagnetic calcium and magnesium impurities by the elemental analysis. Our measurements differ from known results for pure Cu F/sub 2/ .center dot. 2H/sub 2/O and are well explained by the effect of the nonmagnetic impurities in our sample. The purity of our sample derived from the temperature dependence of the susceptibilities was compared with that from the elemental analysis.

새로운 시스템의 수용은 대부분의 경우 유용성이나 사용용이성과 같은 이성적인 평가와 함께 기존 시스템 사용에 대한 무의식적인 습관에 따라 결정된다. 흥미롭게도 기존 시스템에 대한 습관의 효과는 상이한 방향을 가질 수 있다. 어떤 경우에는 전환비용 때문에 부정적이 될 수도 있지만 어떤 경우에는 현 시스템에 대한 풍부한 경험 때문에 긍정적인 효과를 보일 수도 있다. 본 연구에서는 기존 시스템에 대한 습관과 새로운 시스템에 대한 판단 간의 관계가 새로운 시스템에 대한 직접 경험에 따라 달라질 수 있음을 가설로 제시하였다. 즉, 새로운 시스템에 대한 경험이 없으면 부정적인 관계가 되겠지만 경험이 있는 경우에는 긍정적인 관계가 될 수도 있다. 이 가설들에 대한 타당성을 보여 주기 위해 168명의 우리나라 대학생들을 대상으로 실증적 검증을 하였다. 수용 대상은 구글 닥스(Google Docs) 이었고 조사에 참여한 학생들은 이전에 구글 닥스에 대한 경험을 가지고 있지 않았다. 조사 참여자 전부에게 구글 닥스에 대한 특성을 설명한 뒤 임의로 두 그룹으로 나눈 다음 한 그룹은 구글 닥스를 실제 사용할 기회를 주었고 다른 그룹에게는 주지 않았다. 결과적으로 경험을 한 그룹은 기존 시스템에 대한 습관과 새로운 시스템에 대한 주관적 판단 간에 부정적인 관계를 보인 반면 경험이 없는 그룹은 긍정적인 관계를 보였다.

가스 하이드레이트는 물분자와 저분자량의 가스분자가 고압과 저온에서 수소결합을 이루며 형성되는 결정성 화합물을 말한다. 최근 가스 하이드레이트의 물리적 특성과 형성 원리를 이용하여 다양한 분야로의 적용 연구가 수행되고 있는데 이의 효과적 달성을 위해서는 가스 하이드레이트의 상평형 연구가 필수적이다. 기존에 수행되는 상평형 실험 방법은 온도의 변화에 따라 하이드레이트를 해리시키고 압력의 변곡점을 찾는 것으로 최소 24시간이 소요되지만, 본 연구진이 제안하는 QCM을 이용한 방법은 1 ng의 무게에 1 Hz의 변화를 나타내는 수정진동자의 민감성을 이용한 것으로 약 2~3시간 내에 상평형 실험을 수행할 수 있고, 하이드레이트의 기억효과(Memory Effect)를 이용하여 연속적인 상평형 실험도 가능하다. 본 연구에서는 QCM 반응기의 원리 및 실험 방법에 대하여 설명하고 열역학적 촉진제를 첨가한 상평형 실험결과를 제시함으로써 상대적으로 저렴한 가격으로 다양한 촉진제와 억제제 첨가 시 나타나는 상평형 효과를 빠른 시간 내에 선별할 수 있는 방법으로 QCM을 이용한 방법을 제안하고자 한다.
