The study aimed to explore the association between tourism experience and the quality of life among the elderly over aged 65. Using a sample from Jeju, this study clarifies tourism experiences of the elderly and examines the relationship among tourism experience, six different life domains, and overall quality of life by generating theoretical and practical implications. Structural Equation Modeling approach was used to identify the relationships among the constructs. The results revealed that travel experience positively influences satisfaction with family, social, material, psychological, health, and leisure life domain. However, not all life domain satisfaction affects overall quality of life. Satisfaction with family, leisure, health, psychological well-being life domains was linked to overall life satisfaction among the elderly.

This paper describes the Korean Question answering system using the syntactic-relation information d verbs to overcome lack of reliable knowledge and linguistic resources. The syntactic-relation information consists d the original form d a verb, usual usage pattern, semantic category of each dependent noun, synonym verbs and passive verbs. We use the syntactic-relation information to parse sentences or phrases with usual usage pattern of the verb and semantic conditions of dependent components on the verb. We also use that information to parse answer candidate sentences, and find an answer from questioned case slot. Our experiments that usage of the syntactic-relation information of verbs to mm lack of reliable knowledge and linguistic resources can be utilized efficiently for the Korean question answering system.

본 연구의 목적은 치료면의 질에 따른 복합균형운동프로그램이 균형능력에 어떠한 영향을 미치는지 알아보기 위해 본 연구를 실시하였다. 정상 성인 21명을 대상으로 연구를 진행하였으며 복합균형 운동을 실시한 Aero-step군(ASG)과 평지면군(Flat floor group;FFG) 그리고 처치 없이 실시한 대조군에게 Biodex balance system을 이용하여 전체안정성지수(Overall stability index;OSI), 전후안정성지수(Anteroposterior index;APSI), 좌우안정성지수(Mediolateral stability index;MLSI)를 측정하였다. 본 연구 결과에서 전체안정성지수와 전후안정성지수는 Aero-step군의 그룹 내 비교에서 유의한 차이가 있었으며 좌우안정성지수는 평지면군의 그룹 내 비교에서 유의한 차이가 있었다. 전후안정성지수의 그룹간 비교에서 유의한 차이가 있었다. 본 연구의 결과에 따라 치료면의 질에 따른 복합균형운동이 안정된 지지면 보다는 불안정한 지지면의 균형능력 향상에 더 효과적이라 사료된다.

디지털 콘텐츠의 증가에 따라 이들의 효율적인 검색과 관리를 위하여 내용 기반 검색에 관한 많은 연구가 이루어지고 있다. 이러만 내용 기반 검색의 질의 방법으로는 유사한 영상을 질의의 사용하는 QBE(Query By Example)와 영상을 사용자가 직접 스케치하여 질의에 사용하는 QBS(Query By Sketch)가 대표적이다. 본 논문서는 질의로 용할 정확한 영상이 필요한 QBE 방법의 제약과 질의할 영상 전체를 처음부터 스케치해야 하는 QBS 방법의 문제점을 보완하는 개선된 질의 방법을 제안한다. 제안하는 방법은 입력 영상을 단순화하여 스케치의 근간이 되는 밑그림을 제공하고 사용자치 수정 과정을 거쳐 질의하는 방법으로 정확한 검색 결과와 검색 시 소요되는 시간과 노력을 절감할 수 있는 장점이 있다.

In this paper, we propose an efficient data management scheme for path queries and containment queries which are occurred frequently. The proposed data management scheme considers a change of the containment of products during a transport and supports a path of changed products by representing a path of various containments. Also, the compression utilizing the structure of supply chain reduces the stored data volumes. As a result, our method outperforms the existing methods in terms of storage efficiency and query processing time.

인터넷 네트워크의 발달로 3D 콘텐츠와 같은 대용량의 미디어 파일을 인터넷 프로토콜을 이용하여 전송 가능해 졌다. 또한 사용자는 스마트 폰, 스마트 TV, tablet-PC 등과 같은 다양한 디바이스를 통해 인터넷 접근이 가능한 여러 장소에서 원하는 콘텐츠를 전달받아 소비하는 형태가 널리 퍼지고 있다. 이에 따라 안정적인 인터넷 네트워크 환경의 필요성과 IP기반 스트리밍 서비스와 같은 기술의 중요성이 부각되고 있는 실정이다. 하지만 유동적인 인터넷 환경에서는 스트리밍 서비스의 QoS(Quality of Service)를 보장하기 힘들고, 3D 입체영상과 같은 고화질, 고용량의 미디어 파일을 대상으로 할 경우 사용자에게 끊김없는 스트리밍 서비스를 제공하기 어렵다. 이러한 문제를 해결하기 위해서, 인터넷 네트워크 환경을 고려하여 사용자들이 원하는 콘텐츠를 고품질 혹은 저 품질로 제공 할 수 있는 적응적 스트리밍 서비스에 관한 기술 개발이 등장하게 되었고, 현재 국제 표준화 기구인 MPEG(Moving Picture experts Group)에서 DASH(Dynamic Adaptive Streaming over HTTP)라는 이름으로 표준화가 진행 중에 있다. 이에 본 논문에서는 DASH를 이용한 3D 콘텐츠의 적응적 스트리밍 서비스를 위하여 스테레오스코픽 영상의 세그먼트 파일규격 구성방안에 대해서 제안한다. DASH를 이용한 3D 스트리밍 서비스는 사용자들에게 IP 망을 통해 다양한 품질의 3D 콘텐츠를 제공할 수 있으며, 또한 하나의 3D 콘텐츠로 다양한 디바이스에 적용 가능하다는 이점이 있다.

The aims of this study were to investigate the level of activity in the elderly residing in city and rural area and to determine the contributing factors to quality of life (QOL). Subjects were 537 who were older than 60 years of age. QOL was assessed by the SF-36, and the level of activity was assessed by the Korean Activity Checklist. QOL in the elderly residing in city was higher than that in the elderly residing in rural area, and the level of activity was also higher in the elderly residing in city in instrumental activities of daily living, low and high level of physical activity, and social activity compared with the elderly residing in rural area. There was a significant correlation between the level of activity and QOL. The contributing factors to QOL were QOL lower level scores, the Korean Activity Checklist scores, health status, and occupation in the elderly residing in city, whereas the contributing factors to QOL were QOL lower level scores, the Korean Activity Checklist scores, health status, age, and level of education in the elderly residing in rural area. From the findings of this study, the environment in that the elderly can enjoy meaningful activity should be constructed and various programs should be developed.

In Semantic Web, metadata and ontology for representing semantics and conceptual relationships of information resources are essential factors. RDF and RDF Schema are W3C standard models for describing metadata and ontology. Therefore, many studies to store and retrieve RDF and RDF Schema documents are required. In this paper, we focus on some results of analyzing available query patterns considering both RDF and RDF Schema and classify queries on RDF and RDF Schema into the three patterns. RDF and RDF Schema can be represented as graph models. So, we proposed some strategies to store and retrieve using the graph models of RDF and RDF Schema. We can retrieve entities that can be arrived from a certain class or property in RDF and RDF Schema without a loss of performance on account of multiple joins with tables.

The Purpose of the study was to examine the structural relationship among social support(social activity, family/social relationship), emotional problem and quality of life of Elderly Employment Program participants. An analysis was conducted on 2,005 participants from the data of the '2012 Elderly Employment Program Participants Survey'. The major findings were as follows: First, family/social relationship had positive effects and emotional problem had negative effects to quality of life. Second, social activity had negative effects to emotional problem. Finally, social activity had mediator effects to quality of life through emotional problem. Based on the results, the implications for social work practice and policy were suggested.

This study aims to examine how the elderly's internet use affects changes in life, loneliness, self-esteem factors, and life quality. According to the research result, it was found that the elderly's loneliness has a series of relationships with internet use. In other words, the basic model of the initial research suggests as in previous research a hypothesis that internet use relieves the elderly's loneliness; however, according to the final analysis result, the elderly's loneliness is rather a motive that makes them use internet. Also, it was analyzed that as the old's self-esteem gets higher, they show higher satisfaction with their life quality, and internet use affects the improvement of their self-esteem greatly. According to the result of estimating the final model, it was found that the factors of life changes resulted from internet use and influence on the improvement of their self-esteem were far stronger than other variables. Therefore, to improve the old's life quality, it is needed to increase the old's self-esteem, and for improving self-esteem, it will bring a great effect to use the media of internet.
