Background: There is a distinction in alcohol consumption behavior between adults and college students. This study aims to verify the usability and the optimal cutoff point of Alcohol Use Disorders Identification Test-Korean revised version (AUDIT-KR) for screening alcohol use disorder in college students when the diagnostic and statistical manual of mental disorders (DSM), 5th edition diagnostic criteria is applied. Methods: A total of 922 college students living in Daejeon were enrolled and divided into two groups based on how many items they corresponded to among DSM-5 alcohol use disorder diagnostic criteria: those who corresponded to ${\geq}2$ of the 11 items were classified into the patient group (107 males, 89 females) while the others into the control group (311 males, 415 females). The participants were evaluated using AUDIT-KR to find the optimal cutoff point for screening alcohol use disorder, sensitivity, and specificity. Results: The mean${\pm}$standard deviation scores in the AUDIT-KR were $12.76{\pm}7.27$, $10.72{\pm}4.62$ for males and females, respectively, in the patient group. In contrast, in the control group the scores were $6.26{\pm}5.23$ and $3.95{\pm}3.59$ in males and females, respectively. The area under the receiver operating characteristic curve (95% confidence interval) regarding alcohol use disorder screening by AUDIT-KR was 0.768 (0.715-0.821) and 0.883 (0.848-0.919) for males and females, respectively. The optimal cutoff point of alcohol use disorder for males was >9, sensitivity 64.49%, and specificity 76.85%. The optimal cutoff point for females was >6, sensitivity 82.02%, and specificity 80.48%. Conclusion: This study suggested that AUDIT-KR can be used as a screening tool for alcohol use disorder in groups of college students when DSM-5 diagnosis criteria are applied.

The purpose of this study is to analyze and diagnose the curriculum framework of dental hygiene department. Through document analysis process, this study found several empirical data which could give us a clue to understand characteristics of curriculum changes and factors which have impacts on those changes in curriculum at college level. In this study, we could conclude that even curriculum changes at college level had been influenced by social changes like extention of academic years from 2 years to 3 years and changes in licensure test at national level. And also, essential issues in college curriculum like amount of credits, course titles, and requirements-electives distinction etc. also were changed in accordance to social changes and requests. This study found that there is many difference of objectives, credits and course titles among colleges. For that, colleges will form a consultative group under the college level. Based on these results, we can suggest that college curriculum should be flexibly and effectively adapted to changes coping with social and policy changes.

Kompsat-5 is the first Earth Observation Satellite which is equipped with an SAR in Korea. SAR images are generated by receiving signals reflected from an object by microwaves emitted from a SAR antenna. Because the wavelengths of microwaves are longer than the size of particles in the atmosphere, it can penetrate clouds and fog, and high-resolution images can be obtained without distinction between day and night. However, there is no color information in SAR images. To overcome these limitations of SAR images, colorization of SAR images using Cycle GAN, a deep learning model developed for domain translation, was conducted. Training of Cycle GAN is unstable due to the unsupervised learning based on unpaired dataset. Therefore, we proposed MS Cycle GAN applying multi-scale discriminator to solve the training instability of Cycle GAN and to improve the performance of colorization in this paper. To compare colorization performance of MS Cycle GAN and Cycle GAN, generated images by both models were compared qualitatively and quantitatively. Training Cycle GAN with multi-scale discriminator shows the losses of generators and discriminators are significantly reduced compared to the conventional Cycle GAN, and we identified that generated images by MS Cycle GAN are well-matched with the characteristics of regions such as leaves, rivers, and land.

This study tries to study the poetic beauty of the space deconstructed by the medium appearing in Moon Sam-seok's children's poetry to help with simultaneous education and guiding methodology. The research method is based on the assumption that semiotics spatial image is read. In other words, we intend to derive the poetic beauty of the space in which the great pole space built by is deconstructed by the intervention of by the medium term . Among Moon Sam-seok's series of works, the research text is "The Wind and the Fire," "The Wind and the Empty Bottle," "The Wind and Salt," "The Wind and the Rock." According to the study, the wind deconstructed a space that was differentiated by the presence or absence of matter into a "coexistence space." These poetic spaces symbolize poetic beauty as ideal places of life that coexist in a distinction but not discrimination. Second, the wind has eliminated the gap between alienation, suffering and solitude. In other words, the wind deconstructed poetic space produced poetic beauty with the 'space of communication' based on homogeneity of the nature of existence. In conclusion, Moon's poetic speech can be seen that he intended to express the discreteness of the poetic space as 'communication' and 'common life' by deconstructing it with deviation and convergence by introducing a medium.

Although the use of social media by doctors raises important issues concerning medical professionalism, the relevant professional bodies in South Korea have failed to issue clear guidelines on social media usage. The Korean Medical Association's newly revised ethics guidelines do require members to maintain dignity while using social media, but the idea of "maintaining dignity" is far from clear, and its premodern connotation prevents it from being reliably used in professional codes of conduct. The authors of this article examine the concept of maintaining dignity and conclude that once it is clarified and redefined it can and should be used as a viable ethical standard in a variety of contexts, including the use of social media. Social media's unpredictability and uncontrollability, and the blurred distinction between professional/public and personal/private can be a threat to medical professionalism. In order to deal with this threat, the concept of dignity is important. We present three examples in which the dignity of medical professionals is undermined and explain why these jeopardize public trust. We conclude that in order to maintain public trust the Korean Medical Association should provide more detailed guidelines on the use of social media by its members.

This study analyzed the influencing factors for urban redevelopment projects with a relatively long project duration in the context of Seoul's increasing urbanization rate and aging. Among the business areas that have been designated since 2005 and have been approved for the management and disposal plan of the entire Seoul area, 75 business areas have been set as targets. A hedonic price model was used to analyze the project area, economic, and locational characteristics as independent variables with the project duration from designation of zones to approval of management and disposal plans as dependent variables. As a result of the analysis, the smaller the project area, the larger the area occupied per union member, the larger the land price change rate, and the smaller the KOSPI index, the shorter the required period. This study has the distinction of empirically analyzing the effect of characteristic variables considering size and economic and locational characteristics on period. It provides implications that the area of the business area, the number of union members, and economic conditions should be considered when establishing a business area.

Based on spontaneous speech data collected in 2020, this study examined the production and perception of Korean lenis, aspirated, and fortis stops. Unlike the controlled experiments of previous studies, lenis and aspirated stops of males in their 30s were not distinguished by voice onset time (VOT) in spontaneous speech. Perceptual experiments were conducted on young females, the leaders of language change. F0 was found to serve as the primary cue for the perception of lenis stops, and then VOT distinguished the aspirated and fortis stops. The fact that the sounds were always perceived as lenis stops when F0 was low, irrespective of whether VOT was short or long, showed that F0 plays an absolute role in the perception of lenis stops. However, in some cases the aspirated and lenis stops were distinguished only by VOT, which does not happen in production. In terms of sound change, disagreement between production and perception systems occurs when sound change is in progress. In particular, when production change precedes perception change, it indicates that the sound change is in its latter stages. Young females still maintain the previous system in perception because the distinction of lenis and aspirated stops by VOT was valid in their parents' generation. In other words, VOT is still used for perception to communicate with other groups.

Cyber attacks targeting critical infrastructure are on the rise. Critical infrastructure is defined as core infrastructures within a country with a high degree of interdependence between the different structures; therefore, it is difficult to sufficiently protect it using outdated cybersecurity techniques. In particular, the distinction between the physical and logical risks of critical infrastructure is becoming ambiguous; therefore, risk management from a comprehensive perspective must be implemented. Accordingly, as a means of further actively protecting critical infrastructure, major countries have begun to apply their security and cybersecurity systems by design, as a more expanded concept is now being considered. This proactive security approach (CSbD, Cybersecurity by Design) includes not only securing the stability of software (SW) safety design and management, but also physical politics and device (HW) safety, precautionary and blocking measures, and overall resilience. It involves a comprehensive security system. Therefore, this study compares and analyzes security by design measures towards critical infrastructure that are leading the way in the US, Europe, and Singapore. It reflects the results of an analysis of optimal cybersecurity solutions for critical infrastructure. I would like to present a plan for applying by Design.

The purpose of this paper is to examine the determinants of public attitudes toward welfare spending in relation with the perception of welfare level. Data from the national survey of 'the SSK Good Government Research Unit' are used to perform a logistic regression analysis of the association between welfare attitudes and government perceptions, political orientations, and socio-economic backgrounds. The most prominent finding is that the determinants of welfare attitudes differ markedly between the two different groups of welfare perception. The empirical results say that persons living in a corrupt government tend to prefer welfare spendings despite having low level of welfare, and persons living in a unjust government tend to prefer welfare expansion because welfare level must be low. Persons living in a government of great capacity tend to have positive attitudes to welfare spending despite having a high level of welfare, whereas persons living in a government of less capacity tend to have negative attitudes to welfare expansion because the level of welfare is too high beyond government capacity. This distinction between the two perceptions of welfare level provides a systemic understanding of public attitudes toward welfare spending.

The purpose of this study is to critically reflect on whether the higher education(HE) restructuring & funding policy proposed by the Moon administration can properly tackle the structural problems confronting Korean HE system. The three major structural problems having entrenched during the rapid expansion of Korean HE system since 1945 can be identified as (1) a 'high cost - low efficiency system' based heavily on 4-year private universities, (2) lack of clear distinction of the roles and connection among different types of higher education institutions (HEIs), and (3) provider-oriented education system and culture seemingly still being widespread at Korean HEIs. This study analyzed the validity of Moon Administration's HE restructuring and funding policy from both a macro- and micro-perspective. From a macro-perspective, this study raised concerns regarding the projects to nurture a national university and a government-dependent private university which will require huge public money. In terms of both the feasibility to secure enough funds and the validity of the proposed policy measures in the existence of unclear roles between public and private HEIs in Korea, this study criticized these policies and proposed, as an alternative policy measure, a low-cost and flexibly operated HEIs such as a government-dependent polytechnic, and a measure to increase connection between different types of HEIs. From a micro perspective, this study suggested, based on 'the expanded principal-agent theory (Waterman & Meier, 1998)', that it would be considered to introduce a more flexible approach in designing the level of government intervention depending upon the maturity of quality assurance procedure at individual universities and the level of goal conflicts between government and individual university.
