The purpose of this case study is to analyze the economics of journals of Science and Technology using the cost per use(CPU) approach. To achieve this purpose, we selected 1,745 foreign academic journals randomly among the holdings at K institute in Korea, and analyzed the relationships between the CPU and 5 factors of journal, i.e., Impact Factors (IF), Overlap numbers of holding with other institutes, Language, Cost, and Frequency of use. It is found that all factors, except IF, are significantly influence to the CPU of foreign journals, and further detailed analysis is provided in term of the group differences within each factors.

"농업 농촌 및 식품산업기본법" 제47조의 2 신설로 기후변화가 농업 농촌에 미치는 영향, 취약성을 5년마다 조사 평가 공표하고 실태조사를 실시하기 위한 법적 근거가 2014년 5월 마련되었다. 지구 온난화 등 기후변화가 농업 농촌에 미치는 영향을 심층적으로 조사 및 분석하여 기후변화에 선제적으로 대응해야 한다. 국가 수자원 총 이용량의 48%가 농업용수로 이용되고 있다. 논면적(964천ha) 수리안전답은 575천ha에 불과하고, 19.4%(187천ha)는 별도 용수공급시설이 없어 자연강우에 의존하고 있으며, 용수공급시설을 갖춘 관개전은 140천ha로 전국 밭면적의 18.5% 수준('15.7월 행정조사)에 그쳐 논에 비해 열악한 수준이다. 기후변화에 대응하여 농업용수의 안정적 공급을 위해 기후변화에 따른 농업용수의 영향분석 및 취약성 평가를 위한 지표 개발이 시급한 실정이다. IPCC에 따르면 기후변화의 영향과 심각성은 수자원, 생태계, 산림, 보건, 농업 및 사회기반시설 등 다양한 분야에서 관측 혹은 전망되고 있는데 특히 가장 취약한 부분은 강수패턴의 변화로 인한 영향이다. 강수패턴의 변화 의미는 강수 공간, 기간 및 강도의 변화를 의미하는 것으로 강수에 민감한 농업분야가 기후에 가장 먼저 영향을 받는다. 본 연구에서는 기후변화 관점에서 강수의 패턴 변화(공간, 강도, 기간)를 분석하여 농업용수에 미치는 영향을 평가하고자 한다.

Overleaf is a cloud-based LaTeX editor, allowing users to easily create and collaborate on documents without the need for separate LaTeX installation or configuration. Thanks to this convenience, users from various fields worldwide are writing, editing, and collaborating on academic papers, reports, and more via web browsers. However, the caching that occurs during the process of converting documents written on Overleaf to PDF format poses risks of exposing sensitive information. This could potentially lead to the exposure of users' work to others, necessitating the implementation of security measures and vigilance to caution against such incidents. This paper delves into an in-depth analysis of Overleaf's security vulnerabilities and proposes various measures to enhance the protection of intellectual property.

The purpose of this study is to investigate communication efficacy of advertisement text through audience responses. This study approached qualitatively to KT&G TV commercials. The research proceeded as follows: First, as background theory, studies on audience focusing advertisement criticism and the interpretation of advertising texts were reviewed. Secondly, the characteristics of the audiences of the advertisements, analyzed through in-depth individual interviews as well as group interviews, were incorporated into a broad theme and then divided into different dimensions. Finally, the audiences' decoding code and critic reponses in reading ambiguous advertising texts, and the interrelationship between strategic ambiguity were discussed under a unified model. The major findings of this study are as follows: In interpreting the ambiguous advertising texts, the audiences use various decoding codes such as language, visuals, technology and rhetoric, and various critic responses such as linguistic, macroscopic, schematic, non-verbal and socio-cultural factors, in quite comprehensive manner. Also, it was shown that audiences make use of different decoding strategies in terms of their recognition, reliability, emotional attitude, and behavior. It can therefore be concluded that the strategic ambiguity has its limit in explaining its effectiveness in the entire dimensions of recognition, emotional attitude, and behavior, in the sense that the strategic ambiguity is most effective in recognition while it invokes more negativity in the behavioral dimension. Finally, this empirical study, focusing on qualitative analyses, may have its limit as well; however, deeper statistic-qualitative studies in the future could compensate for it.

The purpose of this study is to identify factors influencing treatment result in patients with Tuberculosis by patient characteristic, admission and disease characteristic, and hospital characteristic from 2006 to 2012. Survey data was using Korean national hospital discharge in-depth survey data produced by KCDC(Korea Center for Disease Control and Prevention). Study subjects were 8,305 inpatients with TB(A15.0~A19.9) and analyzed frequency, chi-square test, and logistic regression by using SPSS 20(Statistical Package for the Science). The results of this study show that influencing factors of treatment result were ages (20-39, 40-64, and over 65 years), type of insurance(medical aid), disease code (A16, A17, A18, A19), LOS (31-90, and 91-180 days), beds of hospital (300-499, 500-999, over 1,000 beds) and hospital district (non-metropolitan). These findings implied that it is necessary to support successful prevention and management for high risk TB groups and to build middle and long-term policies as well as short -term policy.

A geological repository system consists of a disposal canister with packed spent fuel, buffer material, backfill material, and intact rock. The buffer is indispensable to assure the disposal safety of high-level radioactive waste. Since the heat generated from spent nuclear fuel in a disposal canister is released to the surrounding buffer materials, the thermal properties of the buffer material are very important in determining the entire disposal safety. Especially, since thermal expansion can cause thermal stress to the intact rock mass in the near-field, it is very important to evaluate thermal expansion characteristics of bentonite buffer materials. Therefore, this paper presents a thermal expansion coefficient prediction model of the Gyeongju bentonite buffer materials which is a Ca-bentonite produced in South Korea. The linear thermal expansion coefficient was measured considering heating rate, dry density and temperature variation using dilatometer equipment. Thermal expansion coefficient values of the Gyeongju bentonite buffer materials were $4.0{\sim}6.0{\times}10^{-6}/^{\circ}C$. Based on the experimental results, a non-linear regression model to predict the thermal expansion coefficient was suggested and fitted according to the dry density.

This study explores the characteristics and ways to improve the area of science education in secondary teacher employment test (hereafter, TET). We investigated ways to differentiate second-phase science education tests from those of the first phase in the TET, and ways to improve practical tests such as designing instructional plans, teaching demonstrations, in-depth interviews, and science experiment tests. Major findings of the study include increasing the proportion of teaching demonstration while maintaining the test of designing instructional plans, which have a different focus from the paper-based exam in the first phase of the TET. Teaching demonstration tests, applying the credit of student-teaching to the TET, assessing teaching expertise in real classroom contexts focusing on subject teaching expertise, etc. along with science experiment tests, making the science experiment test compulsory for all municipal offices of education, and the necessity of evaluating the experimental design and teaching of scientific inquiry. Based on these results, developing and implementing tests such as teaching demonstrations, in-depth interviews, etc. at the local municipal education offices, introducing the apprentice teacher system, and introducing graduate schools of education were suggested.

An effect of coupled thermo-hydro-mechanical and chemical (THMC) behavior is an essential part of the performance and safety assessment of geological disposal systems for high-level radioactive waste and spent nuclear fuel. Furthermore, numerical models and modeling techniques are necessary to analyze and predict the coupled THMC behavior in the disposal systems. However, phenomena associated with the coupled THMC behavior are nonlinear, and the constitutive relationships between them are not well known. Therefore, it is challenging to develop numerical models and modeling techniques to analyze and predict the coupled THMC behavior in the geological disposal systems. It is also difficult to verify and validate the development of the models and techniques because it requires expensive laboratory tests and in-situ experiments that need to be performed for a long time. DECOVALEX was initiated in 1992 to efficiently develop numerical models and modeling techniques and validate the developed models and techniques against the lab and in-situ experiments. In Korea, Korea Atomic Energy Research Institute has participated in DECOVALEX-2011, DECOVALEX-2015, and DECOVALEX-2019 since 2008. In this study, all tasks in the three DECOVALEX projects were introduced to the researcher in the field of rock mechanics and geotechnical engineering in Korea.
