This study aimed to guide the practice of group art therapy among Korean college students through a systematic review. Therefore, 164 studies relevant to group art therapy for Korean undergraduate students published in Korea from January 2001 to June 2021 were selected. This systematic review included 46 publications based on the PICO standards. The author systematically reviewed the included studies, summarized the characteristics and therapy effectiveness, and analyzed the overall research trends. The primary findings were as follows: First, the number of publications on group art therapy among Korean college students has significantly increased. According to a review of group art therapy characteristics, the majority of studies enrolled 6-10 participants (32 studies, 66.7%), applied 6-10 sessions (23 studies, 47.9%), and had an intervention time for each session of 90 minutes (25 studies, 53.2%). Second, research outcomes of group art therapy among Korean college students were grouped into self-related, society-related, emotion-related, and career-related outcomes. Regarding career-related outcomes, all studies found that group art therapy had a statistically significant impact on career-related outcomes, particularly on the levels of career decision-making and maturity. Most studies suggested that group art therapy had a positive effect on self-related, society-related, and emotion-related outcomes, with 6 studies finding no statistically significant effect of group art therapy on college students. Third, the most effective intervention for college students was the media-based group art therapy. In particular, college students had the most effective performance in career-related outcomes. This study is significant in that it uses a systematic review to integrate and summarize research results on group art therapy among college students over the last 20 years. This study revealed that group art therapy could positively and effectively affect Korean college students. Based on this systematic review, we expect to practice and develop group art therapy in Chinese college students with comprehensive guidance and convincing data.

Purpose: The purpose of this study was to investigate the effects and characteristics of health care programs for pregnant women with gestational diabetes mellitus (GDM) in Korea. Methods: This study was conducted according to the Cochrane Collaboration's systematic literature review handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guideline. We searched eight international and domestic electronic databases for relevant studies. Two reviewers independently selected the studies and extracted data. For each study, information on the research method, participants, characteristics of the program, and results were extracted using a previously established coding table. The National Evidence-based Healthcare Collaborating Agency's risk of bias assessment tool for non-randomized studies was used to assess the risk of bias of the included articles. A qualitative review of the selected studies was performed because the interventions differed considerably and the measured outcomes varied. Results: Out of 128 initially identified papers, seven were included in the final analysis. The risk of bias was evaluated as generally low. Health care programs for pregnant women with GDM showed positive effects on blood glucose control. Anxiety and depression were reduced, and self-management and self-care behavior, self-efficacy, and maternal identity improved. Conclusion: Our study provides clinical evidence for the effectiveness of health care programs for pregnant women with GDM, and its results can be used to support the development of health care programs for GDM. More well-designed research is needed on GDM, especially studies that deal with emotional stress and apply a family-oriented approach.

Objectives: No systematic review has explored the challenges related to worldwide universal health coverage (UHC). This study reviewed challenges on the road to UHC. Methods: A systematic electronic search of all studies that identified the challenges of worldwide UHC was conducted, without any restrictions related to the publication date or language. A hand search and a bibliographic search were also conducted to identify which texts to include in this study. These sources and citations yielded a total of 2500 articles, only 26 of which met the inclusion criteria. Relevant data from these papers were extracted, summarized, grouped, and reported in tables. Results: Of the 26 included studies, 7 (27%) were reviews, 6 (23%) were reports, and 13 (50%) had another type of study design. The publication dates of the included studies ranged from 2011 to 2020. Nine studies (35%) were published in 2019. Using the World Health Organization conceptual model, data on all of the challenges related to UHC in terms of the 4 functions of health systems (stewardship, creating resource, financing, and delivering services) were extracted from the included studies and reported. Conclusions: This study provides a straightforward summary of previous studies that explored the challenges related to UHC and conducted an in-depth analysis of viable solutions.

Predictive maintenance has been considered fundamental in the industrial applications in the last few years. It contributes to improve reliability, availability, and maintainability of the systems and to avoid breakdowns. These breakdowns could potentially lead to system shutdowns and to decrease the production efficiency of the manufacturing plants. The present article aims to study how predictive maintenance could be planed into the production scheduling, through a systematic review of literature. . The review includes the research articles published in international journals indexed in the Scopus database. 165 research articles were included in the search using #predictive maintenance# AND #production scheduling#. Press articles, conference and non-English papers are not considered in this study. After careful evaluation of each study for its purpose and scope, 50 research articles are selected for this review by following the 2020 Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA) statement. A benchmarking of predictive maintenance methods was used to understand the parameters that contributed to improve the production scheduling. The results of the comparative analysis highlight that artificial intelligence is a promising tool to anticipate breakdowns. An additional impression of this study is that each equipment has its own parameters that have to be collected, monitored and analyzed.

The purpose of this study is theoretical research on risk. The research is focused on systematic risk. Chapter I is objective of this study, Chapter II includes definition and measurement of risk. Chapter III introduces attitudes toward risk and classification of risk. Chapter IV discusses Portfolio theory, Capital market line and Shape and Lintner model The objective of firm is assumed to maximize its value. In a world of uncertainty, value is not determined by earnings alone, the degree of risk involved with the streams of earnings. Financial manager has to consider the risk in order to maximize the value of firm. Total risk can be classifier into two parts : Systematicrisk and unststematic risk by Sharpe. Systematic risk is important because investors can't diversify it. Blume and Jensen measured f and they testified that the f is stationary over the time For further study, Korean stock mark has to take emperical study about $\beta$ and its stationarity.

Either systematic sampling or stratified sampling is usually applied to the business conditions survey when companies don't have much difference in their size. But the cutoff systematic sampling is an efficient method when only a few companies are so large that the total of them almost equals to the total of whole companies. Throughout this paper, three estimators of total and their variance estimations depending on three kinds of sampling schemes are discussed, and are compared with them via their variances. It is proved that the cut-off systematic sampling is most efficient by using a real data of the logging business conditions survey.

Purpose: This study was to examine the impacts of systematic health education on elementary school students and their health knowledge and health promotional behavior. Methods: This data collected compared 163 students who implemented the seventeen systematic health education behaviors with147 students who did not implement the behaviors during the same period. Results: The health knowledge scores for the implemented group was $18.45{\pm}3.04$ but $15.29{\pm}4.55$for the nonimplemented group. The scores for the implemented group were significantly higher (t=7.26, p<.001). The scores in health promotion behavior for the implemented group was $4.26{\pm}0.41$ and was higher also compared with the scores for the non-implemented group $3.85{\pm}0.50$. The scores for the implemented group were significantly higher (t=3.43, p<.001). The implemented group showed higher health knowledge, health promotion behavior than the non-implemented group. Conclusion: Because systematic health education has significant positive effects on elementary student's health knowledge and health promotion behavior, school health teachers need to maintain and progress continuous systematic health education in their schools.

Purpose: The aims of this study were to identify the psychosocial interventions for patients with alcohol use disorder and to assess the effects of those interventions. Methods: A systematic literature search was conducted using PubMed, the Cochrane Library, Embase, CINAHL, PsycINFO, KoreaMed, KMBASE, RISS, KISS, Science ON, and DBpia to identify studies reported in English or Korean from 2012 to 2021. Results: From the 4,051 studies extracted, 14 studies were selected for review. The majority of the psychosocial interventions were focused on cognitive therapy or cognitive-behavior therapy. Most of the studies reported that the interventions made positive effects on alcohol consumptions. In addition, the psychosocial interventions for patients with alcohol use disorder were effective on coping, support, alcohol avoidance behavior, and hostility bias. Most of the studies reporting positive effects of psychosocial intervention programs applied computers, mobile phones, or similar electronic devices. Conclusion: The findings of this systematic review suggest that the use of computers or mobile devices in psychosocial intervention programs will be effective. It can be said that this systematic review reflects the current trends involving the development of information and communication technology. This systematic review can provide basic data for establishing evidence and suggesting future directions for psychosocial interventions for patients with alcohol use disorder.

In this paper we will introduce an posture error reduction algorithm for Mobile Robot. We classified odometry error into two categories. and focus on systematic odometry error correction only. Because it is the primary reason for mobile robot navigation. For this procedure we used some robot specifications and modeled robot behavior. Through some experiment, we could obtain new system specs. After modeling, Robot navigation precision was improved.
