Side-channel attacks are a quiet mighty type of attack that targets specific physical implementations vulnerabilities. Even though several researchers have examined diverse means and methods of detecting side-channel attacks, at the present time a systematic review of these approaches does not exist. The purposes of this paper are to give an extensive analysis of literature on side-channel attack detection and offer intuitiveness from past research studies. In this study, a literature survey is conducted on articles related to side-channel attack detection between 2020 and 2022 from ACM and IEEE digital libraries. From the 10 publications included in the study, it appears they target either a single type of side-channel attacks or multiple types of side-channel attacks. Therefore, a vital review of each of the two categories is provided, as well as possible prospective research in this field of study.

The purpose of this study is to provide basic data and guideline to STEM(Science, Technology, Engineering, Mathematics) educators who prepare engineering education in elementary and secondary school. For this, this study develops a composition model for engineering education program of elementary and secondary school. To do this, a literature research, experts interview and Delphi survey were conducted. Through the literature research, we extracted the components of model for engineering education program of elementary and secondary school and then made a first draft of the model. The draft was revised by experts while Delphi survey was used to validate the model based on Delphi panels' opinions. The panels for the Delphi survey consisted of 51 experts in the STEM education field. The survey was conducted three different times and importance survey was included in the third stage. The conclusions of this study were as follows: First, the model consist of definition, 4 directions, 4 characteristics, 3 educational goals according to school level, educational contents area and element, teaching and learning method and evaluation method. The educational contents area and element consist of 2 major areas, 7 areas and 18 elements. Second, all components of the developed model were valid in most of the statistics such as mean, standard deviation, the degree of consensus and convergence, and CVR(Content Validity Ratio). Third, importance for education contents area and element according to the school level are analyzed.

This study was conducted for the purpose of developing a basic-level TRIZ curriculum to improve students' creativity and problemsolving abilities. Towards this end, literature review, field application study, and a survey on the demand for such curriculum were conducted, as the research methodologies. Specifically, literature review was performed on the TRIZ-related research trends and education trends, and the researchers, who had experience running a TRIZ education program for a few years, ran a basic-level TRIZ for 40 hours as part of the extra-curriculum of A University. An actual survey was also conducted to determine the demand for the development of a basic-level TRIZ curriculum. Of the total of 40 students who were subjected to the curriculum, 31 responded sincerely 1 to the survey. Based on the survey analysis results on the students' recognition of the TRIZ curriculum and of the TRIZ task performance, and on the contents and educational effects of TRIZ, basic guidelines for the development of a basic-level TRIZ curriculum were formulated. Reflecting the results of the survey on the demand for a basic-level TRIZ curriculum, such a curriculum was proposed based on 16-week-long, 3-credit lectures considering the curricula of other subjects in the university.

In order to achieve the objectives of this research, related literature was examined, a Delphi Survey was conducted. In order to select potential future occupations, this research used a qualitative method that involved interviews with specialists. More specifically, a Delphi Survey was used to collect the specialists' opinions. The potential occupations were selected using a three-prong procedure involving an analysis of related literature and materials, a Delphi Survey, as well the holding of conferences with specialists and visits to those in the actual field. Through this process, 33 different potential future occupations were selected.

The present study is a literature survey aimed at . providing a means to improve the bibliographic apparatuses for Korean studies. The need for a study like this has proven urgent with the promotion of Korean studies both within and without in recent years. The study examines the social science literature on Korea produced in English between 1876 and 1945(A study is under way for literature since 1945 also). Selection of the titles for investigation was made on the basis of the relative importance of the works confirmed after reading book reviews and examining a variety of bibliographies. Each title selected was examined in terms of its subject matter, contribution to the discipline it belongs, references cited, relations with similar works in the field, and bibliographic features. Published books, dissertations both published or not published, and periodicals are included. Primarily a critical review it is also designed to provide background information on the present status of Korean studies and the historical development of Western studies on Korea. Special attenttion is given to the factors contributing to the foundations of the modern Western scholarchip on Korea in the late 19th century.

This study aims to review observational methods for assessing postural loads such as OWAS, RULA and REBA, and to compare them, based on the literature survey. The literature was searched through academic database of ScienceDirect using the key words of observational methods, OWAS, RULA and REBA. The results exhibited that of the thee methods, RULA was cited in the literature and applied to manufacturing industries the most frequently. Although it has been known that RULA is appropriate for assessing upper body postures, it has been applied to healthcare and social work activities, agriculture, forestry, fishing, construction, mining and quarrying, which require unstable lower limb postures. The countries where more number of relevant studies have been carried out were USA, India, Brazil, UK, etc. It was recommended that of the three techniques, RULA may be better for assessing postural loads, because it evaluated postural loads more highly, irrespective of industry, work type and lower limb postures, and its assessment results had higher agreement rate with experts' assessments than those of OWAS and REBA. It is expected that the results of this study will be used as a guideline for selecting an appropriate observational method.

Objectives : The purpose of the study was to investigate the overall research trend and change in dental fear during 9 years(2004-2012) and to identify the major outcomes and future directions to research. Methods : Descriptive literature review was conducted for dental fear in Korea. The research setting should be elementary, middle, high schools and adults. Results : In this study, the literature review of the most used tools to measure fear was that DFS. The most commonly used instrument was Dental Fear Survey(DFS) in the literature review. The number of dacayed tooth was proportional to subjective fear and anxiety. The indirect experience of dental pain was heard from family and friends. So the fear caused the patients to have negative bias toward dental treatment. The negative reliability towards the dentist increased the dental fear to the patients. Conclusions : Through the literature review, dental hygienists are able to understand the dental fear of the patients.

인터넷 이용은 전 세계적으로 아주 빠른 속도로 확산되고 있고 이러한 추세는 한국도 마찬가지이다. 인터넷 성장은 사회 시스템 전반에 큰 영향을 미치고 있으며, 대표적 자료수집방법인 서베이 분야에도 그 영향은 예외가 아니다. 이미 미국, 유럽의 선진국에서는 인터넷 서베이가 크게 각광받고 있으며, 우리나라의 여러 조사기관들도 인터넷 서베이를 실시하고 있다. 인터넷 서베이는 우리나라에도 어느 정도 그 여건이 성숙되어 있다고 볼 수 있다. 그렇지만 아직 응답자의 응답에 영향을 주는 요인에 대한 선행연구조차 정리되어 있지 못하고 있는 설정이다. 본 연구는 전자우편 설문조사에 있어 어떤 요인들이 응답자의 반응, 즉 응답률과 응답속도, 응답품질에 영향을 미치는가 하는 문제에 대한 기존의 연구결과를 정리하고 있다. 문헌연구의 대상으로 포함된 영향요인은 개인화, 조사기관의 성격, 응답자에 대한 보상, 설문지의 물리적 특성, 사전알림, 후속편지의 여섯 개다. 이들 여섯 개 영향요인을 중심으로 전자우편 설문조사를 이용한 기존의 선행연구 결과들을 정리해보고자 한다.

통행을 포착할 수 있는 자료가 양적으로 방대해지며 가구통행실태조사와 같은 전통적 교통조사에 대한 무용론이 제기되고 있다. 그러나 통행의 목적과 수단을 파악할 수 있는 등 가구통행실태조사는 그 중요성이 여전하다. 이에 본 연구는 국내외 교통조사 사례 및 관련 문헌을 검토하여 가구통행실태조사의 현황을 파악하고 개선방안을 논의한다. 본 연구는 가구통행실태조사가 직면한 한계점 중 긴 조사주기, 짧은 조사기간, 유효표출률의 감소, 의무통행 중심의 문항 구성에 대해 다룬다. 이에 대한 개선방안으로 조사주기 단축, 연중조사 시행, 주중조사와 주말조사의 병행 시행, 주말통행 관련 항목 세분화 등을 제안한다. 본 연구는 교통분야 외에 관광, 보건, 사회 등의 분야에서도 응용할 수 있도록 확장성을 감안하며, 제약된 예산 하에서 현실적인 개선방안을 고려한다는 데에 의의가 있다.
