The purpose of this study is to survey of specialists cognition to authorize credits for the same subjects in entering a department of the same area in college among technical high school graduates. Today with generalized college education, about 80% of technical high school graduates enter college. Therefore, authorization of credits for the same subjects is necessary to reduce educational waste in terms of articulation among technical high schools, junior colleges and universities. In this study, a survey was conducted with 100 specialists in technical education, including technical high school teachers, researchers, and professors at junior college or technical college in university, getting answers from 84 subjects (81.25%). The results of this research can be summarized as follows: First, it is valid to authorize credits for all practical subjects completed in technical high school when technical high school graduates enter the same department at college but most of junior college professor unsuitable response. Second, it is valid to authorize credits through its own prescribed test for the same subjects when technical high school graduates enter the same department of engineering at junior college or technical college in university but opposed 62.5% of junior college professor. Third, it is most of respondent valid to authorize credits for the same subjects if results of its own examination for authorization by university are at a fixed level or higher when technical high school graduates are admitted as a junior at the same department in technical college of university after graduation from the same department at junior college.

As part of effort to develop the strategies of internationalization of social science academic journals in South Korea, this study attempts to verify the measurement invariance of journal selection criteria across the groups of library and information science researchers and social science researchers. The authors collected 146 survey responses from researchers who have published at least one paper in SSCI/Scopus-indexed social science journals between 2014 and 2016. As a result of the study, it was found that the configural and partial metric invariance of the journal selection criteria held across the two groups, implying that the model of journal selection criteria is appropriate to use in the field of social science as well as library and information science. Additionally, the authors investigated the perceptions of journal selection criteria indicators in the two groups, and it was shown that researchers in both groups considered peer review and indexing in major databases important. The findings of this study could be useful for publishers or academic societies to develop improvement strategies of their journals.

The purpose of this study is to comparatively analyze academic achievement and class satisfaction in college general mathematics between face-to-face classes and remote classes. For this study, we selected 97 first-year students from three departments of an engineering college at M University. Among the subjects of the study, 39 students in Department A and 36 students in Department B took remote classes using pre-recorded class videos, and 22 students in Department C took face-to-face classes. The subjects of this study were evaluated by one professor as the same type of problem with the same content for the same textbook. Among the subjects of the study, 35 students in department A, 34 students in department B, and 17 students in department C who entered through rolling admissions were collected and homogeneity tests were conducted. And then we analyzed the scores of these students' midterm and final exams for general mathematics in the first semester of 2021. Also, we compared and analyzed the academic achievement and class satisfaction of general mathematics subjects for face-to-face classes and remote classes for all study subjects. The results of this study are as follows. First, there is a significant difference in students' academic achievement of general mathematics between face-to-face classes and remote classes. Second, there is a significant difference in class satisfaction between face-to-face classes and non- face-to-face remote classes.

지문 템플릿(Fingerprint Template)을 보호하기 위해 암호학적 기법인 퍼지볼트(Fuzzy Vault)가 적용되었다. 퍼지볼트 기법은 지문으로 부터 추출되는 특징점을 은닉하기 위하여 지문 템플릿에 다수의 거짓 특징점을 "임의"로 삽입하는 방법이다. 그러나 최근 이러한 지문 퍼지볼트를 효과적으로 크래킹 할 수 있는 상관공격(Correlation Attack)에 관한 연구가 발표되었는데, 이것은 동일한 지문으로 부터 생성되는 두 개의 지문 템플릿을 획득함으로써 진짜와 거짓 특징점을 쉽게 구별하는 방법이다. 본 논문에서는 상관공격에 강인도록 지문 퍼지볼트를 생성하는 방법을 제안한다. 제안한 방법은 특징점의 각도 정보를 이용하여 거짓선분(Chaff Line)을 생성한 후 "규칙적"으로 거짓특징점을 삽입함으로써, 두 개 지문 템플릿을 획득하더라도 동일한 지문에 대해 삽입된 거짓 특징점의 위치와 각도가 유사하기 때문에 진짜와 거짓 특징점을 구별하기 어려워 상관공격을 피할 수 있다. 실험을 통하여 거짓 특징점을 규칙적으로 저장하는 방법을 적용함으로써 기존 방법의 인식 성능을 유지하면서, 상관 공격에 강인함을 확인하였다.

In this study, we analyze South Korea and China have already concluded FTA rules of origin. By comparison and analysis of the relevant provisions in the country of origin of signed FTA, we obtained the necessary implications of origin on the FTA negotiations that will be concluded in the future. FTA between Korea and China's opening level is much lower than the already concluded FTA's, and Korea and the ASEAN FTA has already been signed with similar concessions. However, in understanding the rules of origin in China, it is important for us that China is the first trading partner of the trade. Korean companies are well aware of the rules of origin in China, and it should be noted to prevent damage caused due to the rules of origin in the process of expanding trade with the Contracting Parties.

Although accurate time perception is necessary to properly respond to the environment, it was discovered that non-temporal features also affect time perception. Previous studies have identified various factors that affect time perception, but there was no attempt to directly investigate the possible effects of the distance between participants and the stimuli on time perception. The current study examined the effects of viewing distance on time perception, by considering the retinal, physical, and perceived size of the stimuli. The viewing distance had no effect when either the physical size or the perceived size of the stimulus was the same. Viewing distance was found only to have an effect when the retinal size of the stimulus was the same. This effect might be a size effect rather than a distance effect because as the viewing distance increases the size should also increase to maintain the retinal size. These results imply that temporal perceptual constancy is preserved irrespective of the viewing distance, when distance information is not limited.
