This study presents a meta-analysis research to test the improve effects of obesity and blood lipids on Salicronia herbacea L. (S. herbacea) intake in rats. Individual research materials were selected from database such as PubMed, Embase, RISS, DBpia, and NDSL. The Review Manager 5.3 version was used to estimate effect size through meta-analysis. A total of 9 studies were finally included. Body weight gains were decreased in S. herbacea-treated groups as compared to the high fat diet groups. But, no significant effect was observed on FER, liver index, and total cholesterol. In addition, the effect size of triglyceride was reduced, whereas high density lipoprotein (HDL)-cholesterol was increased in S. herbacea-treated group. In this meta-analysis, the results indicated that S. herbacea have a strong effect on anti-obesity through the blood lipids improvement.

웹 기술 기반의 컨텐츠 개발 및 운영으로 다른 환경에서의 컨텐츠 활용을 토대로 교육자원의 정보들을 통합 운영할 수 있는 관리 중심체인 e-learning 시스템의 중요성과 필요성이 대두되고 교육용 어플리케이션은 현재 표준화되지 않은 개발 프로세스를 기반하여 개발하고 있는 실정이다. 따라서, 국제적 표준인 SCORM(Sharable Content Object Reference Model)을 기반으로 높은 재사용성과 유지보수성을 극대화하기 위해 컴포넌트 개발 방법론(Component Based Development)을 적용해서 체계적으로 교육자원을 개발하고 지원하기 위한 교수-학습지원 시스템에 초점둔 연구가 요구된다. 따라서, 본 논문에서는 컴포넌트 개발 방법론중에서 Unified Process를 이용하여 교수-학습지원 시스템을 정의하고 SCORM기반의 메타데이터를 이용한 컨텐츠저장소에 관한 분석 및 설계를 한다. 이를 통해 실제 교수자가 필요로하는 컨텐츠 제공을 함으로써 재사용성 향상으로 교수-학습지원 시스템의 효율성을 극대화하고자 한다.

본 연구에서는 학술정보의 효율적 관리 및 서비스 체제를 수립하고 활용성을 강화하기 위해 논문 자동 수집 및 구축, 논문 투고 및 심사, 전자출판, XML 자동 구축에 이르기까지 전주기 기능 구현에 방안을 제시하고 이를 구현한 사례를 소개하고자 한다. 기존 Peer-Review 시스템은 데이터 수집 및 변환파트와 투고 및 심사, 전자출판 파트, XML 구축 파트 등으로 분리되거나 별도로 운영되어 왔다. 본 연구에서는 이러한 기능을 통합적으로 구현하기 위해 KISTI의 Peer-Review 시스템인 ACOMS와 XML 기반 학술정보서비스 시스템(KpubS) 기능 및 프로세스를 통합한 구현 방안을 제시하고 이를 시스템으로 구현하였다. 그러나 아직까지 원문 PDF를 XML로 완전 자동 변환할 수 있는 기술은 없는 상태로써 반자동 변환 기능을 탑재하였다. 본 연구 내용은 다양한 수집 채널을 통해 입수된 학술정보 및 XML 자료에 대한 입력체계를 제공하고, XML 본문으로부터 메타데이터를 자동 식별 및 추출하여 학술정보 DB를 구축 저장하며, 구축된 DB 및 XML 기반의 전자출판 기능 제공과 함께 웹서비스 단계까지의 전주기 공정에 대한 프로세스 모델 및 시스템에 관한 것이다. 이에 데이터베이스 구축을 위한 시간 및 비용을 절감할 수 있을뿐만 아니라, 시맨틱 태깅 및 수식, 표, 그림 정보 제공 등 이용자에게 다양한 형태의 서비스를 제공할 수 있게 되었다.

This paper aims to guide experts who manage dementia by exploring the various non-drug interventions and analyzing the effective intervention methods applicable according to the functional level of the elderly with dementia. Fourteen studies were analyzed in this study. Meta-analysis was performed using the means, standard deviations, and the number of samples. Subsequent meta-analysis showed that the Holnis program had the largest effect size in cognitive function, the bakery activity program in memory, and the composite intermediation program with ADL was the largest. In addition, client-centric cognitive stimulation interventions showed the most significant effect sizes, while in depression and BPSD, rhythmic movement activities had the most significant effect size. Elderly with dementia exhibit various symptoms depending on their characteristics and the progress of the disease. Therefore, more efficient arbitration could be provided if the effects of each intervention can be applied differently.

This study seeks to find a way to induce users to expand their direct participation in sports through the acceptance of digital technology. From July 1 to August 30, 2022, a survey was conducted targeting home training users who applied the Internet of Things (IoT). 129 people participated in the survey through non-face-to-face self-administration method. For data processing, frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, multiple regression analysis, and 3-step mediation regression analysis were conducted using IBM's SPSS 21.0 program. The results of the study are as follows. First, in the relationship between the home training PPM model and direct participation in sports, ease appeared to have a mediating effect. In the factors of push, simple functionality showed a complete mediating effect, and inefficiency showed a partial mediating effect. Among pull factors, enjoyment and possibility of experience showed a complete mediating effect. In the mooring factors, individual innovativeness showed a complete mediating effect. Second, in the relationship between home training PPM model and direct participation in sports, usefulness showed a mediating effect. In the factors of push, simple functionality showed a complete mediating effect, and inefficiency showed a partial mediating effect. Among pull factors, enjoyment and possibility of experience showed a complete mediating effect. Among the mooring factors, individual innovativeness showed a partial mediating effect. Through this research, it is expected that the sports industry will contribute to the expansion of consumption expenditure and economic growth through the expansion of digital technologies such as NFT, Metaverse, and virtual/augmented reality.

The semantic web is taken as next generation standards of information exchange on the internet to overcome the limitations of the current web. To utilize the information on the semantic web, tools are required the functionality of query search and reasoning for the ontology. However, most of semantic web management tools cannot efficiently support the search for the complex query because they apply Triple-based storage structure about RDF metadata. We design the storage structure of the ontology in corresponding with the structure of ontology data and develop the search system(SMART-DLTriple) to support complex query search efficiently in this research. The performance of the system using new storage structure is evaluated to compare with the popular semantic web management systems. The proposed method and system make a contribution to enhancement of a practical ontology reasoning systems due to improved performance of the ontology search.

In this paper, we confirmed that an efficient sensor network can be established at a low cost by applying Geofencing technology to a LoRa-based sensor network and verified its effectiveness in disaster management such as forest fires. We detected changes through GPS, gyro sensors, and combustion detection sensors, and defined the validity size of the Geofencing cell accurately. We proposed a LoRa Payload Frame Structure that has a flexible size according to the size of the sensor information.

최근 기계학습 기술의 급속한 발전에 힘입어 자율주행을 위한 객체 인식 및 처리 기술 역시 비약적으로 발전하고 있다. 그러나 이러한 기계학습의 성능은 모델의 구조와 학습용 데이터의 품질에 영향을 받는다. 특히 주행환경을 잘 표현하는 학습데이터가 중요한데 전혀 새로운 도로, 주행환경, 장애물, 정적 혹은 동적 객체 등을 마주하면 정확도와 안정성에서 부정적인 영향을 받을 수 있는 것이다. 해외의 주행 데이터들에 크게 의존하고 있는 우리나라의 현실에 비춰 볼 때 국내 환경에 맞는 학습데이터를 쉽고 효율적으로 확보/관리/분석할 수 있게 하는 환경의 구축이 시급하다. 따라서 본 논문에서는 자율주행을 위한 기계학습 데이터를 효과적으로 관리하고 분석하기 위한 소프트웨어를 설계하고 개발하였다. 구체적으로는 수집된 영상들을 관리하는 기능, 영상에 존재하는 노이즈 제거 및 화질 개선 처리 기능, 학습 및 검증을 위한 메타 정보 태깅 기능, 태깅 정보의 통계적 분석 기능들을 포함한다. 개발한 소프트웨어는 우리나라에서 자체 촬영한 자율주행 학습 영상들에 대해 딥러닝 모델들을 학습하고 검증하는데 활용할 예정이다.

Recently, The sensor technology Has been used in many fields, it is detected data of various types of sensors, is very difficult to integrate due to differences in the standards and each other unit. Also, when we providing a service or program on a data cloud, it is important that integrates of such data in order to take advantage of the detected data in the similar field. In this paper, we propose a approaches to integrating data to be provided as a service in the cloud of data arising from a heterogeneous sensors. The approaches are generating a standard meta-data based on ontology, it is mapping with detected data by the sensor data. Accordingly, the detected data is possible to improve the efficiency of data transfer between the sensor and the application by sending an application in a standard format.
