Purpose: The aim of this study was to determine the reliability and validity of the metacognition rating scale (MCRS), which is a revised version of the existing metacognition questionnaire (MCQ) with anger and anxiety added. Methods: A survey was conducted on 591 nursing students at colleges in North and South Gyeongsang Provinces, South Korea. The collected data were processed for the reliability and validity of the MCRS through Cronbach’s α and confirmatory factor analysis using SPSS 26.0. Results: Cronbach’s α for the reliability of MCRS was calculated at .88, .86, .77, .74, and .66 for five subfactors. Among the five subfactors, the first, second, third, and fifth factors showed high correlation in each of six items. Factor 4 was highly correlated in 5 out of 6 questions. Conclusion: The data confirm that the MCQ revised to include anger and anxiety is both reliable and valid for nursing students. Therefore, this scale can be used to identify the maladaptive metacognition of nursing students in stressful situations.

Juels와 Sudan의 퍼지 볼트 기법은 기법이 갖는 오류 내성 때문에 많은 연구에 사용 되어오고 있다. 그러나 이들의 퍼지 볼트 기법은 그들의 논문에서 영화 애호가 문제를 예를 들었음에도 불구하고, 사람들이 일반적으로 갖는 선호도(preference)의 차이에 대한 고려가 존재하지 않는다. 한편, Nyang과 Lee는 안전하고 성능이 좋은 얼굴인증 시스템을 만들기 위해서, 얼굴 특징이 서로 다른 가중치를 갖도록 얼굴 특징과 퍼지 볼트(vault) 사이에 특별한 연관 구조를 갖는 얼굴 인증 시스템(이른바, 퍼지 얼굴 볼트)을 소개하였다. 그러나 그들의 기법은 일반적인 특징 추출 기법들이 클래스 내부/간 차이를 최적화하려는 특성이 있기 때문에 인증 실패율을 성공적으로 낮추지 못할 것으로 쉽게 예상할 수 있다. 이 논문에서는 퍼지 볼트의 유연성을 제공해주기 위하여 Nyang과 Lee의 퍼지 볼트기반의 얼굴 인증 시스템에서 가중치 아이디어를 다른 방식으로 구현한 버킷(bucket) 구조와 사용자 선호도와 시스템 구현 간 관계를 공식화하는 세 가지 분포 함수에 대해서 소개한다. 또한 이를 바탕으로 선호도 매치메이커(preference matchmaker) 기법을 제안하며, 영화 데이터베이스를 이용하여 이러한 매치메이커의 연산 성능을 확인해본다. Juels and Sudan’s fuzzy vault scheme has been applied to various researches due to its error-tolerance property. However, the fuzzy vault scheme does not consider the difference between people’s preferences, even though the authors instantiated movie lover’ case in their paper. On the other hand, to make secure and high performance face authentication system, Nyang and Lee introduced a face authentication system, so-called fuzzy face vault, that has a specially designed association structure between face features and ordinary fuzzy vault in order to let each face feature have different weight. However, because of optimizing intra/inter class difference of underlying feature extraction methods, we can easily expect that the face authentication system does not successfully decrease the face authentication failure. In this paper, for ensuring the flexible use of the fuzzy vault scheme, we introduce the bucket structure, which differently implements the weighting idea of Nyang and Lee’s face authentication system, and three distribution functions, which formalize the relation between user’s weight of preferences and system implementation. In addition, we suggest a matchmaker scheme based on them and confirm its computational performance through the movie database.

연결불가능성(unlinkability)과 추적불가능성(traceability)은 그룹서명이 만족해야 하는 기본적인 요구사항이다. 본 논문에서 최근 Lee등과 Zhu등에 의해서 제안된 두 그룹 서명기법들이 갖는 취약점을 분석하였다. Lee등의 기법은 합법적인 서명자가 생성한 서명을 검증할 수 없는 설계상의 치명적인 문제를 갖고 있으며, 검증과정이 안고 있는 문제와 별개로 동일한 서명자가 생성한 서명을 항상 링크할 수 있음을 보인다. 또, Zhu등의 그룹서명기법에서 그룹의 관리자가 추적할 수 없도록 서명을 생성하는 것이 가능함을 보이고, 저자들의 주장과 달리, 그들의 기법이 전방향 안전성을 만족하지 않음을 보인다. Unlinkability and traceability are basic security requirements of a group signature scheme. In this paper, we analyze two recent group signature schemes, Lee et al.'s scheme and Zhu et al.'s scheme. We show that Lee et al.’s scheme does not work correctly. Further, it fails to meet unlinkability, that is, anyone who intercepts or receives group signatures are able to check if they are from the same signer. We also show that Zhu et al.'s scheme is unable to satisfy traceability, that is, a malicious group member can generate valid group signatures that cannot be opened. Moreover, once becoming group member, the malicious group member will never be revoked from group. Besides, Zhu et al.'s scheme fails to satisfy forward security, a requirement claimed by authors.

한국어 프레젠테이션 능력 향상을 위한 기호 읽기 교육 연구 -학습자 발표에 나타난 기호의 언어화를 중심으로-

이경희 ( Lee¸ Kyunghee ) 한국언어문화교육학회 2021 언어와 문화 Vol.17 No.3

This study aims to examine what Korean language learners should learn to restore symbols of presentation materials in natural sentences. How to verbalize the compressed content of visual materials in the presentation is significant. Symbols are a typical way used to compress content. Therefore, restoring symbols to complete sentences is an essential element of presentation ability. This study analyzed the process of Korean language learners organizing visual materials and using them to present them. In particular, we focused on how they expressed symbols in vocabulary, grammar, and sentence patterns in the target language. The significance of the study is that it reminded us of the importance of verbalizing symbols in the Korean language presentation. (Kyung Hee University)

Objective: This study was performed to examine the relationship between community-based social support and psychosocial distress in workers. Methods: The study subjects were 596 workers recruited from 11 companies in Chungju city. A structured questionnaire was used to assess sociodemographics, health-related behaviors, job characteristics, job stress, work-based social support, community-based social support and level of psychosocial distress. Results: Hierarchical multiple regression analysis showed that workers with no chronic disease, exercise and sufficient sleep had a higher score of psychosocial distress than those with chronic disease, no exercise, and not enough sleep. Coworker's work-based social support and community-based social support were negatively associated with psychosocial distress. The R square value of total independent variables on psychosocial distress was 0.409, and that of community-based social support on psychosocial distress was 0.052. Conclusion: This study showed that community-based social support served as a protective factor against psychosocial distress in some workers. We recommend the establishment of a worksite stress reduction program in occupational level as well as community-based social support.

다양한 멀티미디어 서비스의 등장으로, 네트워크를 통한 멀티미디어의 원활한 전송에 대한 요구가 높아지고 있다. 이에 따라 이러한 기술 들을 검증하고 실험하기 위한 멀티미디어와 네트워크의 통합 프레임워크의 필요성은 높아졌다. 따라서, 이 논문에서는 멀티미디어의 네트워크 전송에 관한 연구를 위한 새로운 프레임워크를 제안한다. 본 프레임워크는 멀티미디어 프레임워크를 네트워크 시뮬레이터에 통합하여 멀티미디어 프레임워크에서 지원되는 다양한 멀티미디어 코덱을 시뮬레이터와 연동하여 사용하게 하고 네트워크 상태를 피드백으로 멀티미디어 프레임워크에 주어 수용하게 한다. 이 프레임워크는 기존 연구에 비해 다양한 코덱 지원, 네트워크 피드백기반 멀티미디어 코딩, 실시간 비디오 전송 관찰 등의 장점이 있다. 또한 제안된 프레임워크의개별 연구를 수행하여 그 효용성을 입증하였다.

동서양 음악미학 고찰을 통한 한국음악의 정체성 연구(1) : 고대 그리스 음악관과 「예기」에 나타난 음악사상비교 The Musical Thoughts of Ancient Greece and Yueh Chi (樂記)

이경희 민족음악학회 2003 음악과 민족 Vol.26 No.-

It is not an easy task to answer the question, How can we define Korean music in the whirl of 21th-century globalization? For the first stage to define the identity of Korean Music in the 21th century, the author chose the method of comparison between music aesthetics of Eastern and that of Western. In order to diagnose the present situation, the author thinks that it would be helpful to go back to the roots of the musical thoughts of both cultures. In the part of Eastern music aesthetics, the author reviewed the Confucianism first among the various traditional thoughts in the history of Korean music. Yueh Chi (樂記) or the Book of music, Especially which was originally contained in Li Chi (禮記), was chosen as the representative text which contained the fundamental musical thoughts of Confucianism. On the other hand, in the part of Western music aesthetics, various writings of the representative philosophers such as Plato and Aristotle were consulted. Although there was no actual interaction between Ancient Greece and China, the striking similarities of both musical thoughts attracted the author and led to investigate the reason why ancient people in both cultures viewed music in similar ways. In this paper, three common aspects of musical thoughts in both cultures were chosen, i. e. cosmological, moral (educational) and political aspects. The present Korean music consists of various musics from different historical backgrounds and viewpoints. If we would find the common basis for various musics by investigating the both roots of Eastern and Western musical thoughts, we could make some positive steps forward to understand the identity of Korean music. The author hopes that such trial could contribute to set the place and direction of Korean music in the map of the world music. However, keeping in mind that it could not be done within a short period and with one trial, the author will expand and develop this research into broad areas and various methods.
