The purpose of this study was to systematically review about randomized controlled trials the characteristics and effect of cognitive function intervention for patient with dementia. We searched studies published from January 2010 to June 2021 in 5 databases. A total 1,104 studies were found and included 27 studies in final analysis. Methodological quality was assessment with the Cochrane's RoB(risk of bias) tool. Mini-Mental State Examination(MMSE) was the most used as the assessment tool for identifying the cognitive function. Cognitive function intervention were exercise, art, cognitive stimulation, reminiscence, music, multimodal cognitive rehabilitation, virtual reality, horticultural, computerized cognitive training, intentional snoezelen, beauty, cooking, korean traditional familiarity program. Most of the intervention except exercise 2, virtual reality 1, beauty 1 were effective in improving cognitive function. This study provided a clinical evidence for planning and implementing intervention for cognitive function intervention. In the future, various intervention studies suitable for the characteristics of dementia should be conducted by improving the quality of research methods.

With the increased creation, distribution, and use of image in context of the development of digital technologies and internet, research endeavors have accumulated drastically. As two dominant aspects of image retrieval have been considered content-based and concept-based image retrieval, concept-based image retrieval has been focused in the field of Library and Information Science. This study aims to systematically review the accumulated research of image retrieval from the perspective of LIS field. In order to achieve the purpose of this study, two data sets were prepared: a total of 282 image retrieval research papers from Web of Science, and a total of 35 image retrieval research from DBpia in Kore for comparison. For data analysis, systematic review methodology was utilized with bibliographic analysis of individual research papers in the data sets. The findings of this study demonstrated that two sub-areas, image indexing and description and image needs and image behavior, were dominant. Among these sub-areas, the results indicated that there were emerging areas such as collective indexing, image retrieval in terms of multi-language and multi-culture environments, and affective indexing and use. For the user-centered image retrieval research, college and graduate students were found prominent user groups for research while specific user groups such as medical/health related users, artists, and museum users were found considerably. With the comparison with the distribution of sub-areas of image retrieval research in Korea, considerable similarities were found. The findings of this study expect to guide research directions and agenda for future.

The purpose of this study aimed to examine the effects of ecological systems factors on childhood depression. A total of 2,119 children data from 2013 Korean Children & Youth Panel Survey(the fourth wave)were used in this study. The results of hierarchical regression showed the most ecological systems factors; organisms(child's gender, aggressiveness, attention problems), microsystems(parental neglect, parental abuse, good relationships with friends), exosystem(supportive community environment); had effects on depression. The most influential factors were child's aggressiveness, parental abuse, good relationships with friends, supportive community environment. Finally, this study suggested some implications for practical intervention and further research in childhood depression.

지금까지의 한국어 자연언어 처리에 기반이 되는 사전 품사 체계에 대한 연구는 형태소 분석, 구문 구조 분석, 그리고 의미 분석 등의 다양한 분야에서 이루어져 왔다. 한국어 자연언어 처리 각 분야는 자체의 고유한 독립성을 가지는데, 이러한 특성은 사전 품사 체계의 다양화를 초래하였으며, 연계성있는 자연언어 처리를 위한 통합 환경 조성을 저해시켜 왔다. 본 논문에서는 한국어 자연언어 처리 전반에 걸친 통합 환경 조성을 위한 범용적인 사전 품사체계의 필요성에 따라 한국어 자연언어 분석의 각 분야에 적합한 사전 품사체계에 대하여 살펴 본 후, 한국어 자연 언어 처리 전반에 사용될 범용적이고 통합적인 기본 사전 품사체계 구축을 위한 방안을 제시한다.

최근 공공기관 및 금융권에서는 경쟁력 향상을 위한 정보시스템의 통합으로 프로젝트 규모가 대형화되고 또한, 프로젝트 수가 증가하고 있어 적절한 소프트웨어 프로젝트 관리 방안이 필요하다. 그러나 프로젝트 관리 영역간의 미치는 영향에 대하여 체계적인 연구가 미흡하였다. 따라서 선행 연구를 통하여 프로젝트 관리에 중요한 영역을 도출하였고, 도출된 "범위, 일정, 품질, 인력, 위험"의 각 영역들간의 상호 미치는 영향도의 분석과 각 영역의 진행 상태를 "계획, 실행, 완료" 단계로 구분하여 수행도를 분석하였다. 분석된 영향도와 수행도의 결과를 종합하여 프로젝트 관리 수준을 평가하는 모델을 제시하였다. 본 연구는 IT 분야의 전문가 그룹을 통해 프로젝트 관리 영역들간의 영향 분석이 실증적으로 연구가 이루어졌고, 또한 각 영역의 진행상태를 측정 함으로써 실무적인 측면에서 더욱 체계적이고 균형 잡힌 프로젝트 관리와 감리 수행 시에 활용할 수 있을 것이다.

The purpose of this study is to systematically analyze the results of the existing research on mathematical beliefs, compare and synthesize the valuable results and to suggest implications for mathematical beliefs and research. As a result of checking the methodological quality of 59 articles in total using the MQA(Methodological Quality Assessment) checklist, most of them surveyed mathematical beliefs using questionnaires, and most of the studies were conducted on prospective teachers. As a result of systematic review, the conceptual characteristics of mathematical beliefs, object-specific characteristics, and the educational influence of mathematical beliefs were able to synthesize the meaning. Mathematical beliefs had important educational influences in the practice of teachers, students, and math classes. As the results of the study, we emphasize the importance of changing the beliefs of students and teachers in order to solve the problem of mathematical education, where students rely on private education rather than activity thinking, and teachers do not pay attention to students thinking. It has been shown that concrete support is needed for practicing participatory instruction focused on mathematical thinking.

The systematic validation of the ITS devices' performance reliability is very important because it helps their performance reliability to be maintained in a certain level, enabling to assure the reliability of the collected data, processed data and provided information. Although the government's regulation, "Transportation Efficiency Act", which requires ITS devices to be validated, was passed in 2001, no systematic inspection and calibration procedures have been developed so far. Therefore, in this study the systematic and efficient inspection and calibration method or procedure is investigated by reviewing the similar cases and best practices in Korea and overseas and some recommendations are made.

The purpose of this study is to review systematically the literatures on the research of the elderly speech signal processing based on the domestic gender innovation and to introduce the utility and innovation of the gender analysis methods. From 2000 to present, among the 37 research papers published in the Korean Journal, 25 papers were selected according to the inclusion and exclusion criteria. And gender analysis methods were applied to gender research subject and design. Research results show diversity of research field and high gender recognition of R & D team are needed in research and development of engineering of gender innovation perspective. In addition, government-level regulation and research funding should be systematically applied to gender innovation research processes in the elderly voice signal processing and various gender innovation projects. In the future gender innovation in the elderly speech signal processing can contribute to the creation of a new market by developing a voice recognition system and service that reflects the needs of both men and women.
