In order to analyze the current status of trade with Korea and FTA partner countries, the Trade Intensity Index and the Market Comparative Advantage index were calculated and analyzed using panel gravity model. In the case of trade, trade intensity index has been strengthened according to each FTA enforecement, and in some cases, trade inensity has been weakened. In the case of the comparative advantage index, there was a case in which the comparative advantage was strengthened or the comparative advantage was not significantly changed according to each Chapter of HS code. This means that the Korea's FTA enforcement effect has not directly affected the increase of the trade intensity and the increase of the market comparative advantage index. The panel gravity model using the trade intensity and the comparative advantage index as the dependent variable and the trade volume between the two countries as the dependent variable was analyzed.

Visualization of the homology information is an important method to analyze the evolutionary and functional meanings of genes. With a database containing model genomes of Homo sapiens, Mus muculus, and Rattus norvegicus, we constructed a web­based comparative analysis tool, BioCovi, to visualize the homology information of mammalian sequences on a very large scale. The user interface has several features: it marks regions whose identity is greater than that specified, it shows or hides gaps from the result of global sequence alignment, and it inverts the graph when total identity is higher than the threshold specified.

Purpose - This study, in seeking to understand the trade structure of both Korea and China, aims to strengthen Korea-China economic cooperation; it examines trade impediments by analyzing the problems affecting trade and addressing these problems, thereby discovering ways to expand trade between these countries. Research Design, Data, and Methodology - The index of trade intensity developed by the trade intensity theory (Kruger, 1997) is used to analyze the trade decision factors of both countries. Although specific factors should have materialized from the analysis of trade decision factors, determining concrete explanations is difficult in reality, as there are many unsolved and diverse factors. Results - First, the index of A value/B value is the index of Korean versus Chinese market share/Korean versus world market share, which is a measure of comparative market intensity. Second, Korea has a comparative advantage in export specialization and, conversely, China has a comparative advantage in import specialization. Third, compared to 2000, the revealed comparative advantage (RCA) indexes are considerably improved. Conclusions - This study used quantitative measurement for analysis, applying trade intensity theory, trade specialization, and RCA indexes to gauge how inter-trade relations have changed between Korea and China during the past 10 years (2000, 2005, and 2012).

This study focused on the analysis of residential satisfaction and environment awareness depending on the environment-friendly level on the outdoor space of the housing complexes. The purpose of this study is to present basic materials of the environment-friendly outdoor space planning of housing complexes. The major findings of the study are as follows. First, the results of the comparative analysis of the satisfaction of the outdoor space of apartment complexes show that the complexes with the most application of environment-friendly elements had higher residential satisfaction. But there was no meaningful statistical difference between the complexes with the higher level of application of the environment-friendly elements and the complexes with medium level of application. Secondly, according to a comparative analysis, the overall residential satisfaction of the apartment complexes was the same as the residential satisfaction of the outdoor space. Thirdly, the results of the correlative analysis of residential satisfaction and environmental awareness showed that the satisfaction of the apartment complexes decreases as the awareness of the environment-friendly apartment complex increases. The results of this study can be used as basic materials for environment-friendly outdoor space planning of apartment complexes.

Background: Toxoplasma gondii can infect humans and most animals and has a very high infection rate worldwide, including in China. The number of people infected with T. gondii in China increases with the number of cats. Objectives: We investigated the seropositive rate of T. gondii in cats over the last five years and analyzed the risk factors via meta-analysis. Methods: We retrieved 20 studies, with a total of 5,158 cats, published between 2016 and 2020, used the DerSimonian-Laird model and calculated seroprevalence estimates with the variance stabilizing double arcsine transformation. Results: The overall seroprevalence rate after sinusoidal conversion was 19.9% (95% confidence interval [CI], 15.9-23.9; 966/5,158), lower than the domestic report from 1995 to 2015 (24.5%, 95% CI, 20.1-29.0). There was substantial heterogeneity among studies (χ² = 262.32; p < 0.001; I² = 64.6%). Regression analysis of possible heterogeneous causes and subgroup analysis showed that age and whether cats were stray or not have a significant effect on the seropositive rate. Conclusions: Articles published in recent five years suggest that the seroprevalence estimates of Toxoplasma gondii in cats has decreased. Cats, as the final host of T. gondii, are an important cause of the spread of the parasite, and this is an important concern for public health.

Purpose: A network meta-analysis was conducted to assess the comparative effects and ranks of repositioning for pressure ulcer prevention in adults. Methods: A network meta-analysis was performed in a frequency method, using the "netmeta" package of R software version 4.1. The effects of repositioning intervention were confirmed by the odds ratio. The comparative ranking of the repositioning effects was confirmed using the cumulative probability (P-score). Results: Seven intervention studies were included in this study. Based on the P-score, the use of the repositioning system was ranked as the most effective among all interventions (P-score 78.7%). Next was 3~4-hour repositioning combined with memory foam mattress use (P-score 77.2%), use of wearable sensor (P-Score 61.4%), 2-hour repositioning combined with memory foam mattress use (P-score 59.1%), 2-hour repositioning combined with powered air pressure redistribution mattress use (P-score 18.0%), and 4-hour repositioning combined with powered air pressure redistribution mattress use (P-score 18.0%). Conclusion: This study provides information on the relative comparative value of various repositioning interventions to prevent pressure ulcers using network meta-analysis. This is expected to be useful for nurses' decision-making when applying repositioning interventions in clinical practice

The cultural identity of each nation has appeared as a major issue in this multi-cultural era, and needs to define It clearly through comparisons with other cultures have been raised. The purpose of this study is to figure out ‘similarity’ and ‘dissimilarity’ on design characteristics of traditional storage furniture in interior context of Korea, China and Japan. Comparative analysis of traditional furniture was conducted in two terms, in terms of inner space, first, spatial elevation and front patterns, second, flooring materials of the interior space and types of furniture legs. Result of first comparative analysis showed that composition of windows, one of the major decorative elements of interior space, positively influenced on furniture, and reflected unique patterns of each country. Second comparative analysis showed that structures and shapes of traditional furniture vary depending on flooring materials. As a result of it, Korean furniture has the structure of ‘punghyeol’ and Chinese furniture has the structure of ‘aja’ with ‘takni’ , a combination of legs. In contrast to the two countries, Japanese furniture has rarely legs. The result of analysis is expected to act a role of establishing the cultural identity of our own country.

The study examined and compared relationships among self-esteem, self-efficacy, and academic achievement of children in poverty and the comparative groups. The subjects of this study were 97 elementary school students who had benefited from the free meal project and 97 students as the comparative group who did not receive the benefit. Descriptive statistics, Cronbach's ${\alpha}$ tests, and multiple regression analysis were employed to analyze the data. The results showed that academic scores of the comparative group were statistically higher than those of children in the poverty group in Korean language, mathematics, science, and sociology. Also, self-esteem of children in the poverty group was lower than that of the comparative group's in terms of leadership and popularity. The poverty group also showed lower self-efficacy in self-regulated efficacy tasks. Finally, multiple regression analysis demonstrated that different sub-factors of self-esteem and self-efficacy predicted the academic achievement of children in poverty group and the comparative groups.
