  • The purpose of this study was to extract the evaluation factors and assess the relative importance between the factors. For this purpose, the evaluation factors were extracted through literature review and the process of brainstorming with experts, who are related to port security. The evaluation factors were then classified into four higher factors and twelve sub- factors through the use of the AHP method. A survey on the classified factors was conducted by experts composed of public officials, port authority employees and education institutions officials. We also carried out statistical tests to determine the perception gap of weights between the groups. As a result of a relative importance analysis of strength, the security operating system factor was highest, followed by improvement of hardware facilities and increase of security personnel. There was a difference in perception among the groups in policy support, facility support and personnel resources budget support. The results of the analysis show that the strength operating system through the establishment of an integrated monitoring system is a priority. It is necessary to understand the difference of perception between groups and build a systematic cooperation system. The evaluation factors extracted from this study can be used for the measurement of port security efficiency in further work.

  • Objective : Shunt infection is a common complication while treating hydrocephalus. The antibiotic-impregnated shunt catheter (AISC) was designed to reduce shunt infection rate. A meta-analysis was conducted to study the effectiveness of AISCs in reduction of shunt infection in terms of age, follow-up time and high-risk patient population. Methods : This study reviewed literature from three databases including PubMed, EMBASE, and Cochrane Library (from 2000 to March 2019). Clinical studies from controlled trials for shunt operation were included in this analysis. A subgroup analysis was performed based on the patient's age, follow-up time and high-risk population. The fixed effect in RevMan 5.3 software (Cochrane Collaboration) was used for this meta-analysis. Results : This study included 19 controlled clinical trials including 10105 operations. The analysis demonstrated that AISC could reduce the infection rate in shunt surgery compared to standard shunt catheter (non-AISC) from 8.13% to 4.09% (odds ratio [OR], 0.48; 95% confidence interval [CI], 0.40-0.58; p=0.01; I2=46%). Subgroup analysis of different age groups showed that AISC had significant antimicrobial effects in all three groups (adult, infant, and adolescent). Follow-up time analysis showed that AISC was effective in preventing early shunt infections (within 6 months after implant). AISC is more effective in high-risk population (OR, 0.24;95% CI, 0.14-0.40; p=0.60; I2=0%) than in general patient population. Conclusion : The results of meta-analysis indicated that AISC is an effective method for reducing shunt infection. We recommend that AISC should be considered for use in infants and high-risk groups. For adult patients, the choice for AISC could be determined based on the treatment cost.

  • The purpose of this study is to develop a perceived elderly stigma scale for intergenerational research and practice. Although negative stereotypes on elderly population have worsened physical and psychological health of older people, there has been a lack of systematic efforts to measure and monitor stigmatic perception and behavior of younger generation on elderly people. We initially constructed a 34-item perceived elderly stigma scale, by integrating the processes of literature review and exploratory item generation. After confirming the face validity of the scale, a 31-item perceived elderly stigma scale was tested with 252 adults recruited from an online research panel. The result of an exploratory factor analysis suggests a 5-factor solution with 28 items: ability, personality, appearance, authoritarian dependancy, and family-obsession. The convergent/discriminant validity was confirmed by examining its relationships with ageism, elderly discrimination, attitude toward elderly, and respect for elderly. After a series of refinement and empirical tests, the perceived elderly stigma scale would contribute to understanding the current state of elderly discrimination in our society and to develop necessary policies and promotion strategies to eliminate intergenerational conflicts.

  • Objective : The purpose of this study was to verify the effect of virtual reality interventions (VRIs) on cognitive function in individuals with stroke through a systematic literature review and meta-analysis. Methods : We reviewed randomized controlled trials (RCTs) the last 10 years using academic databases. PubMed, MEDLINE, and CINAHL were used for international studies, and DBpia, KISS, Kyoboscholar, and e-article were used for Korean studies. For the quantitative meta-analysis, subgroups of outcomes were classified into general cognitive function (G-CF), attention and memory (A&M), and executive function (EF). Results : Nine RCTs were analyzed. The total number of participants was 271 (140 in the experimental group). The effect size (Cohen's d) was estimated using a random effects model. The effect sizes of the outcome subgroups of were as follows: small to medium for G-CF (d=0.422; 95% CI: 0.101~0.742; p=0.010), small for A&M (d=0.249; 95% CI: -0.107~0.605; p=0.170), and medium for EF (d=0.666; 95% CI: 0.136~1.195; p=0.014). Conclusion : Considering the various stimuli provided by the virtual environment and the results from available research, virtual reality should be applied to interventions for integrated cognitive functions. In addition, it would be appropriate to be used as an additional intervention to traditional cognitive rehabilitation for stroke.

  • The purpose of this study was to determine the present state of disabled people participating fully in sports for all, analyze its legal, organizational, and policy status, and present a future direction for parasports in pursuit of better sports welfare. For this purpose, literature review was performed, obtaining the following results concerning a parasports activation plan. First, it is necessary to increase large-scale, systematic public relations through association between the government and private organizations with the objective of increasing the number of disabled people participating fully in sports for all. Second, it is necessary to implement full revision of the Sport Promotion Act and establishment of a Parasports Promotion Act actively. Thorough preparation for legislation is most of all required to meet the realities and cope with temporal changes. Third, it is necessary to build an effective system through convergent governance of parasports and relevant ministry. It is necessary to clarify the dual concepts of 'physical activity' and 'sports for all,' present a proper direction for policies, and implement efficient policies and projects. Fourth, it is necessary to reinforce participation by diverse expert groups in the development of parasports policies. This requires convergence of such elements as philosophy, rehabilitation, education, marketing, and laws in addition to sport elements.

  • It is not easy to predict the future society in the rapidly changing present, but it is said that a new social environment of sensibility and virtuality will come, and we should pay attention to the fact that women have entered this as the subject. This study is a literature review study on gender roles. Through the study, it was found that gender stereotypes that exist in our society allow men to enjoy a lot of vested rights just by being male, and that women have to endure pain because they are women is accepted as a matter of course. Living in the 21st century, we were able to know the reality that we could not escape the pre-modern patriarchal ideology and still worshiped the idea of preferring boys. Through this study, unlike other elderly groups, elderly people who live alone are likely to be cut off from society and lead a limited life in their own world. However, through the efforts of the government, local organizations, and individuals, the goal of welfare for the elderly is to increase the satisfaction of life for the elderly living alone so that they can enjoy a successful old age. From this point of view, the support measures for the elderly living alone will be effective only when systematic and complementary in various dimensions such as family structure, physical, economic, and social aspects.

  • In this study, trends in ICT education were investigated by analyzing the frequency of appearance of keywords related to machine learning and using conversion of iteration correction(CONCOR) techniques. A total of 304 papers from 2018 to the present published in registered sites were searched on Google Scalar using "ICT education" as the keyword, and 60 papers pertaining to ICT education were selected based on a systematic literature review. Subsequently, keywords were extracted based on the title and summary of the paper. For word frequency and indicator data, 49 keywords with high appearance frequency were extracted by analyzing frequency, via the term frequency-inverse document frequency technique in natural language processing, and words with simultaneous appearance frequency. The relationship degree was verified by analyzing the connection structure and centrality of the connection degree between words, and a cluster composed of words with similarity was derived via CONCOR analysis. First, "education," "research," "result," "utilization," and "analysis" were analyzed as main keywords. Second, by analyzing an N-GRAM network graph with "education" as the keyword, "curriculum" and "utilization" were shown to exhibit the highest correlation level. Third, by conducting a cluster analysis with "education" as the keyword, five groups were formed: "curriculum," "programming," "student," "improvement," and "information." These results indicate that practical research necessary for ICT education can be conducted by analyzing ICT education trends and identifying trends.

  • This study was conducted for the purpose of the basic direction for the new regulations and categories of Ruralism changing in the new era. To this end, the results of Delphi analysis and AHP analysis by dividing it into the definition, criteria, scope and component items of Ruralism based on systematic literature review are as follows. First, through studies representing most rural areas, it was found that Ruralism was the most problematic keyword and most of the studies did not cover it as they were studying various ranges of rural areas. Second, the Delphi survey was able to derive keywords that can be used as evidence for item classification and clear concept establishment for the regulation and category setting of Ruralism. Third, through the hierarchical decision-making method, it was found that landscape factors are the most important thing in forming Ruralism as well as deriving priorities that can be a baseline for each item. This study is meaningful in providing a minimum baseline as basic data for establishing the concept of Ruralism, and it is believed that future-oriented Ruralism can be established if reviews are added from various perspectives to overcome limitations dependent on expert groups.
