The purpose of this study was to verify the clinical utility of th Korea Child Behavior Checklist 16-18(K-CBCL 6-18) in diagnosing ADHD among children with psychological disorders in child welfare institutions. The participants were 509 elementary school children(309 boys and 200 girls) who lived in child welfare institutions. They were assessed using the Korean ADHD Rating Scale(K-ARS) and K-CBCL 6-18. Only five scales of the K-CBCL 6-18 related with attention were used for analysis: syndrom total, externalizing total, aggressive behavior, attention problems and DSM-oriented ADHD scales. The results were as follows. First, K-ARS and K-CBCL 6-18 had significantly positive correlations with all five scales. Second, as a result of a t-test on the ADHD and the non-ADHD groups, which were divided using K-ARS, the mean scores of ADHD group were significantly higher than the non-ADHD group for all five scales of the K-CBCL 6-18. The hit rate of all five scales of the K-CBCL 6-18 was 60 to 70 percent. The syndrom total and externalizing total scales had high sensitivity, whereas the aggressive behavior, attention problems, and the DSM-oriented ADHD scales had high specificity. In addition, all scales had high positive predictive values. Third, as the result of a t-test on the ADHD group and the emotional disorder group, there were significant difference in the mean scores of the attention problems and the DSM-oriented ADHD scales. The attention problems and the DSM-oriented ADHD scales had a similar percentage of hit rate, high specificity and low sensitivity. Especially, the DSM-oriented ADHD scale revealed higher specificity than the attention problems scale. The results of this study suggested that the five scales related to attention of the K-CBCL 6-18 are useful in diagnosing ADHD in child welfare institutions.

Recently, the aspect of regulating the legal system in North Korea has increased in quantity and shows the improvement of the evaluation of the lack of systematic consistency in the past. North Korean legislation has been negatively criticized for its lack of function and role of the legislative body and ambiguity of the legal system. In particular, the newly adopted "Legislation Law" in relation to the revision of the legislative system of North Korea contains important and clear contents to understand the legislative system and procedures of North Korea. The contents of the "Legislation Law" can be found a glimpse of the process by which the framework and procedures of the North Korean legislative process are organized more systematically. The North Korean legislation provides legal and institutional grounds for promoting internal and external policies under the Kim jong-un's regime. North Korea is focused on the nuclear issue, so there is limited information on other areas. In light of this, the purpose of this study is to examine the legislative theory and system of North Korea, and outline the theoretical basis of North Korea's emphasis on strengthening socialist judicial life, the socialist legal system, and the state theory of socialist rule of law. In addition, it can be analysed the content of actual legal reform in light of North Korea's legislative theory and system. In the study, it will examine the legislative system of North Korea and its characteristics by examining the legislative process and legislative process of North Korea. Moreover, it can be compared the contents of the Legislative Law of China with the legislative process of the DPRK and examine its characteristics. We will look at the challenges to the legislative system in North Korea and look into the future direction of the legislation. Kim jong-un's announcement of the revised legislation until recently through the publication of the 2016 Supplementary Codes is an important data for the current state of the North Korean legislation. This is because it confirms the content of the laws and regulations already known through "Democratic Chosun(a newspaper issued by North Korea Cabinet)'s statutory interpretation." However, in the case of laws and regulations related to the North Korean political system, it is still a remnant of the lagging legislation that the announcement is delayed, or it remains undisclosed or confidential. North Korean laws are developed and changed according to the changes of the times. In particular, the contents of the maintenance of foreign investment and the foreign economic law system and related internal legal system are found to change in accordance with the development direction of the socioeconomic system. If the direction of Kim jong-un's regime is to be expanded to the path of reform and opening up in the economic sector, the revision of the related laws and regulations will accelerate. Securing the transparency and objectivity of the North Korean legislative process and procedures will help to broaden the understanding of the inter-Korean legal system and to seek institutional measures for inter-Korean integration. In the future, in-depth research on the North Korean legal system will be emphasized as a basis for ultimately forming a unified Korea's legal system.

In this paper, the main subjects with which I deal are as follows: (1) Is Distancing Philosophy from the real ruling power a way of practical-philosophical resistance, based on social reformation as a axiological directivity of Kim Tae-Gil's ethical thought, though it is negative type of resistance? Or is it a sort of transformed value-free opportunist behavior which allows antidemocratic ruling group to coerce the people into submission, assuming an uncompromising stand seemingly? (2) Is Kim's defense argument on the opening of the course of National Ethics and the all-out activation of National Ethics education under Park's Yushin Regime derived from his own philosophical belief? Or is it brought out from the external conditions and circumstances surrounding Kim Tae-Gil which forces him to participate in the national undertaking for the settlement of the course of National Ethics in the university? The 'provisional' answers about the two subjects are as follows: (1) Kim's Distancing Philosophy is a type of practical philosophical revolt against the dictatorship power under Yushin Regime, though it is negative form of resistance. We can accept this philosophical elucidation above all by confirming the fact that the reform of reality is the main ethical trait running through his entire ethical thought system. However distancing philosophy disclose the crucial limits to allow itself to boil to the philosophical practice compromising with real ruling power eventually, though it is intended upon its own social ethical directivity and conviction. (2) The primary factor which affects Kim to propose such an advocation argument on the course of National Ethics and the education of National Ethics is the external conditions and circumstances surrounding him, especially the power-relation between he and ruling group and intimate human relation between he and his superior philosophers who carries out the role of a ideologue for the Yushin Regime, rather than his own philosophical belief. But no matter what primary factor, Kim's action to make a advocating argument to support the course and the education of National Ethics is to blame, on that account that he cannot adequately his social responsibility and role given to him as a reformist moral philosopher who will pursue the realization of righteous democratic society. Along with that, It is not too enough to criticize him sharply for such defending action. The reason is that his supporting stance for National Ethics education is brought out, by not adhering closely to the philosophical way of distancing from the dictatorial power devoid of political legitimacy and moral justification.

The present study was carried out with a view to understand the distribution and ecology of Clihton retropictus (Martens, 1879), a class II endangered wildlife designated and protected by the Ministry of Environment, Republic of Korea, and to suggest the effective conservation and management measures for this species and its habit. First, the distribution of Clihton retropictus was investigated nationwide, and environmental factors such as salinity and substratum were analyzed in consideration of the ecological characteristics of this species. In addition, the individual size, density, and movement of Clihton retropictus per each district surveyed were analyzed. Due to its nature of inhabiting in the brackish water zone, the analysis showed that the salinity of this species was 0.7 ~ 16.6‰ at low tide and 1.0 ~ 17.3% at high tide. It was learned from the analysis of substratum that its composition in each river under investigation was slightly different, but most of substratum had a higher composition ratio than gravel (pebble, 16 ~ 64 mm). On the other hand, the size of each individual was checked by measuring the length of its diameter, and there was almost no change in the individual when the inhabited range of Clihton retropictus was short. However, there was tendency that the longer the habitat range, the bigger the individual size. From surveying the population density by season, it was made clear that, during the summer (July to August) and fall (September to October), the density was relatively higher while the number of individuals decreased significantly during winter (November to December) when the water temperature was lowered. In an effort to effectively establish conservation and management measures, the moving distance was measured, and it became known that, during the surveys in summer and fall when the individuals were active, the individuals moved in more distances than during the winter survey. The results of this study are expected to be utilized as basic data for establishing effective management plans such as creation of habitats for Clihton retropictus, its migration projects and selection of migration destinations which get unavoidable due to development projects.

Objectives: This study was carried out to understand the seroprevalence and risk factors for severe fever with thrombocytopenia syndrome (SFTS) among the Korea National Park Service (KNPS) workers. Methods: We used the stored serum samples (763) and survey results collected from the previous investigation on scrub typhus and Lyme disease among the KNPS workers during 2016-2017. The serum samples were analyzed by double-antigen sandwich enzyme-linked immunosorbent assay, which was used to test the total antibody including IgG and IgM. Results: The SFTS seroprevalence among the KNPS worrkers was 1.4%. In multivariate logistic analysis, the national park exploration programs (odds ratio, 3.48; 95% confidence interval, 1.01-12.01) was significantly associated with the seroprevalence of SFTS. Conclusion: This study was the first serological study of SFTS among forestry workers in South Korea. Although the KNPS workers are at a high-risk group of SFTS, the prevention activities related to the working environment and habit was insufficient. Thus, systematic prevention education and training for the KNPS workers need to be strengthened.

This study analyzed the healing effect of the design elements of healing environment from the perspective of environmental stress, which is one of the contents of environmental psychology. By examining the objective healing effects of the design elements of the healing environment, this study attempted to prepare a theoretical basis for contributing to the construction of a systematic and systematic healing environment. This study consists of three phases. Firstly, three environmental stress theories (Attention Recovery Theory, Evolutionary Psychology, and Environmental Stress Model) were examined to review the academic basis of which the theoretical concept of the healing environment has been derived and developed. Second, we analyzed 16 previous research on the design elements of healing environment and used them as an analysis framework of this study. Thirdly, 11 foreign studies that proved the healing effects of healing environment design elements through objective research methods were considered and analyzed as an analysis framework, and the basis for applying design elements in constructing healing environment was prepared. The research results are as follows. First, the concept of healing environment was developed from Lazarus's psychological stress theory and Ulrich's theory of evolutionary psychology, suggesting that it can be used as one of the noninvasive healing tools that affect stress reduction. Second, the healing environment design elements could be divided into 15 factors and categorized as physical environment, psychological environment, and social environment, and it was found that most of them were mentioned and studied in the previous research in order of nature-friendly, aesthetic, and openness. Third, most of the previous research on the healing effects of the design elements of the healing environment were related to natural affinity and aesthetics, and it was found that the visual elements of the healing environment could affect the actual stress reduction.

This research aims to provide the characteristics of the world's first active lidar sensor Atmospheric Laser Doppler Instrument (ALADIN) wind data and Geostationary Korea Multi Purpose Satellite 2A (GK2A) Atmospheric Motion Vector (AMV) data by comparing two wind data. As a result of comparing the data from September 2019 to August 1, 2020, The total number of collocated data for the AMV (using IR channel) and Mie channel ALADIN data is 177,681 which gives the Root Mean Square Error (RMSE) of 3.73 m/s and the correlation coefficient is 0.98. For a more detailed analysis, Comparison result considering altitude and latitude, the Normalized Root Mean Squared Error (NRMSE) is 0.2-0.3 at most latitude bands. However, the upper and middle layers in the lower latitudes and the lower layer in the southern hemispheric are larger than 0.4 at specific latitudes. These results are the same for the water vapor channel and the visible channel regardless of the season, and the channel-specific and seasonal characteristics do not appear prominently. Furthermore, as a result of analyzing the distribution of clouds in the latitude band with a large difference between the two wind data, Cirrus or cumulus clouds, which can lower the accuracy of height assignment of AMV, are distributed more than at other latitude bands. Accordingly, it is suggested that ALADIN wind data in the southern hemisphere and low latitude band, where the error of the AMV is large, can have a positive effect on the numerical forecast model.

The extraction of polyphenol and flavonoid from citrus peel was performed by the ethanol, sugar, hot water (80$^{\circ}C$), and subcritical water extraction methods. The maximum yields of total polyphenolic compounds (27.25${\pm}$1.33 mg QE/g DCP, QE and DCP indicate quercetin equivalent and dried citrus peel, respectively) and flavonoids (7.31${\pm}$0.41 mg QE/g DCP) were obtained by subcritical water extraction (SWE) with operating conditions of 190$^{\circ}C$, 1300 psi, and 10 min. The yields by SWE were over 7.2-, and 8.5-fold higher than those of total polyphenols (3.79${\pm}$0.73 mg QE/g DCP) and flavonoids (0.86${\pm}$0.27 mg QE/g DCP) obtained using the ethanol extraction, which showed the highest extraction efficiency among tested conventional methods, respectively. Antioxidant activities of extracts obtained by different methods showed no significant differences. However, the relative antioxidant yield per 1 g dried citrus peel by SWE (190$^{\circ}C$, 10 min) was over 9.5-fold higher than that by the ethanol extraction.

The extraction of polyphenol and flavonoid from black rice bran was performed by diverse extraction methods using the sugar solution, ethanol, hot water ($80^{\circ}C$), and by subcritical water extraction (SWE) method. By SWE under operating conditions of $190^{\circ}C$, 1,300 psi, and 10 min, the maximum yields of total polyphenolic compounds (35.06${\pm}$1.28 mg quercetin equivalent (QE)/g dried material and flavonoids (7.08${\pm}$0.31 mg QE/g dried material) could be obtained. These results were over 11.77- and 12.21-fold higher than those of the ethanol extraction, which showed the highest extraction efficiency among tested conventional methods in total polyphenols (2.98${\pm}$0.74 mg QE/g dried material) and flavonoids (0.58${\pm}$0.21 mg QE/g dried material), respectively. Though the highest antioxidant activity (87.14${\pm}$1.14%) was observed at the dried extract obtained from ethanol method, the relative antioxidant activity per 1 g dried black rice bran by SWE ($190^{\circ}C$, 10 min) was over 11.53-fold higher than that by the ethanol extraction.

Nowadays Korean main archives and manuscript repositories are planning to develop archival information service for students and teachers in their web sites. This study is aimed at discovering main issues of developing archival information service for students and teachers and finding a solution. The goal of archival information service for students and teachers is the promotion of use through launching service and the gradual growth of archival management program. The customer group is segmented into the students and teachers who are learning and teaching Korean history in classroom. As a result of analyzing curriculum and educational environment, the archival information must be developed into teaching-learning materials. And the processing archival information into archival content is needed. Consequently the character of archival information service for students and teachers is conceptualized as archival content service for teaching-learning materials. At every step of developing archival content service for teaching-learning materials, the next main points are considered and achieved. First, the strategy of customer-focused service must be the same from beginning to end. Second, the growth of traditional archival management(e.g. classification, description and finding aids) must be contributed. Third, the collaboration system leading by professional education staff must be organized. Fourth, the archival information must be related with teaching-learning activities. Fifth, the quality of content is more important than the quantity of it. Sixth, the networking with another agencies for cooperation must be considered.
