This paper presents comparative analysis of the traits of personal network structure shaping in local press organizations of Korea. For this analysis, this study attempts to investigate three topics. First, the density traits of personal network structure in the whole of local press organization. Second, the comparison of density trait shaping in personal network structure between press section of local broadcasting stations and local newspaper companies. Third, the positional trait in each local press organization. To answer the questions, the data concerning commissioners and executive members in local daily newspapers and local broadcasting organizations from the Civic Government to the People's Government have been collected and analyzed. The interconnections of regional(birthplace) and educational(university graduated) aspect were analyzed via methods of cross analysis, density analysis and correspondence analysis. In brief, major findings of this study are as follows ; As a result of analyzing cross analysis and density analysis of the personal network based of regional and educational aspect, the numerical value of density was too high on the whole of local press organizations. But, especially local newspaper companies has been showed that was higher density compared with press section of local broadcasting stations. And, positional distance between local press organizations were showed obviously in the case of regional(birthplace) aspect. But, in case of educational aspect, positional distance were showed obviously between commissioners and executive members.

Heat wave is a disaster, which increases morbidity and mortality in temperate regions. Climate model results indicate that both intensity and frequency of heat wave in the future will be increased. This study shows the result about relationship between excess mortality and offensive airmass in 7 metropolitan cities, and an operational Heat-Health Warning System (HHWS) in Korea. Using meteorological observations, the Spatial Synoptic Classification (SSC) has been used to classify each summer day from 1982 to 2007 into specific airmass categories for each city. Through the comparative study analysis of the daily airmass type and the corresponding daily mortality rate, Dry Tropical (DT), and Moist Tropical plus (MT+) were identified as the most offensive airmasses with the highest rates of mortality. Therefore, using the multiple linear regression, forecast algorithm was produced to predict the number of the excess deaths that will occur with each occurrence of the DT and MT+ days. Moreover, each excess death forecast algorithm was implemented for the system warning criteria based on the regional acclimatization differences. HHWS will give warnings to the city's residents under offensive weather situations which can lead to deterioration in public health, under the climate change.

In this paper insights from studies on the middle income trap and value chains analyses are combined to investigate one particular industry in one particular region: the sugarcane industry in Northeastern Thailand. Focusing on this region enables an in-depth focus on geographical differentiation of the middle income trap. The empirical outcomes demonstrate that policymakers involved with sugar should look at the particular challenges in Northeastern Thailand: 1. The role of brokers which is unaddressed in the current regulatory environment; 2. A lack of information of the regulatory environment among growers; 3. Distrust between growers and millers; 4. Alack of implementation of R&D efforts; 5 .A lack of support from associations; 6. The labor shortage problem, and 7. No incentives for growers, brokers and millers to improve quality and embark on upgrading. Since agricultural value chains in Southeast Asia often start in relatively poor rural areas it is imperative that policymakers balance the interests of upstream, midstream and downstream actors. Unfortunately, this is rather difficult as midstream actors (millers) and wholesalers are powerful and therefore, are in the best position to defend their interests. Our insights could function as comparative material for similar studies within other Southeast Asian upstream value chains.

Recently. the interest in Physical distribution has increased in economic geography This paper aims to review and prospect the internatonal physical distribution studies of international trade and international freight flows. And it has examined the changes in methodology of international physical distribution. Author has defined international physical distribution as the physical distribution of international trade and international freight flow The results are as follows : (1) As the methodology of international physical distribution studies developes, the physical distribution should be recognized not only as transportation phenomenon but also as total logistics which is understood as the combination of production and consumption including information flow. (2) The studies about model of international physical distribution flow ill need to study regional relations including urban, in the future. And economic geography and location theory adding culture and behaviour elements will be restructured, because not only state but also multinational corporation appear as trade subject in global economy. (3) The studies for the relation of habor and its hinterland in Physical distribution need to analyze the factors causing habor use with decision-making behaviour of corporation. (4) After oil crisis. as air freight is important, the studies for hinterland and foreland of freight centering international airport are needed because of necessity of light and small freight. flexible Production system, free trade, and high speed freight transportation of freshing food and flowers and so forth.

The Ministry of Education and Human Resources Department of Korea have formulated various policy for development of teacher's ICT competence. But most of efforts expended upon ICT utilization currently, emphasize the ability which can handle computer skillfully than the ability for practical use in instruction, so that cannot induce distinct competence according to the duties and operations of teachers. This study aims to make scales for teacher's ability of ICT utilization in education of Korea. For the original purpose of evaluation, this tool made by job analysis and comparative studies with the existing appraisal standards. It can be the standards for evaluation of teacher's wholly duties on ICT applied education and proper self-evaluation tool for improvement of teacher's ability on ICT utilizing instruction. I processed measurement value of participant of Gwangju and Jeollanamdo area in this system and analyzed the level of teacher's abilities using ICT, a sex gap, regional difference, duty position difference and education career difference etc.

The discussion of this paper is concerned with the epistemology of urbanism and rurality, that is, the justification of certain knowledge claims about how to intervene in understanding of urban and rural way of life and their implications to space. It is not concerned with the search for "truth" as such, but rather with the construction and presentation of knowledge as truth that subsequently lead to interpretation in the form of scholarly arguments. Rural areas vary considerably, and we define it as of a socially constructed category and so does urban as a comparative construction. As with community, rurality has been defined in widely different ways so has urbanism. In identifying and interconnecting these two concepts, we incorporate diverse western epistemologies such as empiricism and pragmatism. In addition, we heed particular attention to the intellectual history of Silhak, a philosophical ideology of Korea, to identify the relationships and it's effect on social way of life encompassing the realm of rural and urban spaces. We found that Silhak is particularly useful in that it deals with substantive issues of the relationship between rurality and urbanism arising from the discordance between values and perceive conditions of the rural and urban way of lives. This paper argues that the epistemology of Silhak is particularly superior to those of western ideologies since it accentuates unity of spaces rather than differentiating urban and rural way of life. We concludes with demanding more studies in the field of urban and rural analyses incorporating more diverse concepts of Korean orthodox epistemology.

The objectives of this research were to evaluate antioxidant activities and nutritional components, including phenolic acid, catechin, organic acid, sugar, and amino acid, of persimmon juice from persimmons grown in different regions around Korea. Persimmon (Diospyros kaki) exhibits potent antioxidant effects in DPPH, ABTS, reducing power, and FRAP methods of analysis. The levels of nutritional constituents showed significant differences among all the samples. In particular, tartaric acid, glucose, gallic acid, epicatechin gallate and aspartic acid were observed to be the predominant component for each of their general chemical groups, with total average contents of 1876.51 mg/kg, 62.69 g/kg, 12.73 mg/kg, 208.99 mg/kg, and 31.84 mg/100 g, respectively. Interestingly, persimmons from the Hadong region presented the highest sugar (130.60 g/kg), phenolic acid (42.27 mg/kg), and catechin (527.97 mg/kg) contents in comparison with other regional samples. Moreover, this location exhibited the greatest antioxidant activity with highest total phenolic (298.01 mg GAE/kg) and flavonoid (32.11 mg/kg RE) contents. Our results suggest that strong antioxidant activities of persimmons correlate with high phenolic acid and catechin contents, particularly gallic acid and epicatechin gallate. Additionally, these two compounds may be key factors when considering the useful ingredients of persimmon.

This paper studies the change process and characteristics of the 'Korean community cinema movement'. The community cinema movement that has been active since the 2010's can be said to be a turning point in the Korean film culture movement. However, academic and policy definitions and research on the community cinema movement are extremely insufficient and only appear in some seminars or policy research reports. This study aims to discover the characteristics of the 'Korean community cinema movement' in the flow of the Korean alternative screening movement. A comparative study through a diachronic approach to the Korean alternative screening movement and case analysis of community cinema is intended to identify the characteristics of Korean community cinema and suggest policy measures for which a support system has not yet been prepared.

Recently, attention to the pandemic situation represented by COVID-19 emerged problems caused by unexpected shortage of medical personnel. In this paper, we present a method for diagnosing the presence or absence of lesional sign on PA chest X-ray images as computer vision solution to support diagnosis tasks. Method for visual anomaly detection based on feature modeling can be also applied to X-ray images. With extracting feature vectors from PA chest X-ray images and divide to patch unit, region-specific abnormality can be detected. As preliminary experiment, we created simulation data set containing multiple objects and present results of the comparative experiments in this paper. We present method to improve both efficiency and performance of the process through hard masking of patch features to aligned images. By summing up regional specificity and global anomaly detection results, it shows improved performance by 0.069 AUROC compared to previous studies. By aggregating region-specific and global anomaly detection results, it shows improved performance by 0.069 AUROC compared to our last study.
