  • Information providers on WWW have been rapidly increasing, and they provide a vast amount of information in various fields, Because of this reason, it becomes hard for users to get the information they want. Although there are several search engines that help users with the keyword matching methods, it is not easy to find suitable keywords. In order to solve these problems with a specific domain, we propose an intelligent information agent(HHA-la : HongIk Information Agent) that converts user's q queries to forms including related domain words in order to represent user's intention as much as it can and provides the necessary information of the domain to users. HHA-la h has an ontological knowledge base of animal domain, supplies necessary information for queries from users and other agents, and provides relevant web page information. One of system components is a WebDB which indexes web pages relevant to the animal domain. The system also supplies new operators by which users can represent their thought more clearly, and has a learning mechanism using accumulated results and user feedback to behave more intelligently, We implement the system and show the effectiveness of the information agent by presenting experiment results in this paper.

  • For efficient and precise searches in the Web environment, resources should be coded in a structured way. HTML does not cover semantic structure because of its fixed tagging. XML, which has emerged as an alternative standard markuplanguage, uses custom tags that allow structural searching. Therefore, this study aims to compare XML with HTML in terms of their characteristics and retrieval functions. In order to test retrieval functions of XML- and HTML-based systems, we constructed an experimental XML-based system. The XML-based system has several advantages over the HTML system. However, some improvements are needed to make the XML system more comprehensive and effective. First, XML document search engines with user-friendly interfaces are needed. Second, popular Web browsers such as Explorer and Communicator need to support XML 1.0 specification completely. Third, Open DTD format, which will allow information retrieval systems to retrieve documents and compress them into one single format, is also needed to control Web documents more efficiently.

  • Purpose: The purpose of this study was to provide a basis for non-humidified low flow oxygen by nasal cannula and to provide a guide for consistent care in nursing practice. Methods: A methodological study on the development of guidelines with experts' opinions on collected items, framing PICO questions, evaluating and synthesizing texts which were searched with the key words (low flow oxygen, nasal cannula, humidification of oxygen, guideline) from web search engines. Results: Of the 45 researched texts on the web, 9 texts relevant to the theme were synthesized and evaluated. All patients with humidified or non-humidified oxygen therapy reported that they had no discomfort. Conclusion: The results indicate that there are no tangible grounds for patients' perceived differences between the humidified and non-humidified oxygen under 4L/min supplied by nasal cannula. with oxygen. Therefore, non-humidification oxygen therapy is strongly advised when suppling under 4L/min oxygen by nasal cannula (recommended grade A).

  • Ontologies have provided supports in integrating heterogeneous and distributed information. More and more ontologies and tools have been developed in various domains. However, building ontologies requires much time and effort. Therefore, ontologies need to be shared and reused among users. Specifically, finding the desired ontology from an ontology repository will benefit users. In the past, most of the studies on retrieving and ranking ontologies have mainly focused on lexical level supports. In those cases, it is impossible to find an ontology that includes concepts that users want to use at the semantic level. Most ontology libraries and ontology search engines have not provided semantic matching capability. Retrieving an ontology that users want to use requires a new ontology selection and ranking mechanism based on semantic similarity matching. We propose an ontology selection and ranking model consisting of selection criteria and metrics which are enhanced in semantic matching capabilities. The model we propose presents two novel features different from the previous research models. First, it enhances the ontology selection and ranking method practically and effectively by enabling semantic matching of taxonomy or relational linkage between concepts. Second, it identifies what measures should be used to rank ontologies in the given context and what weight should be assigned to each selection measure.

  • Purpose: This study was to analyze the trend of research on intervention for patients with metabolic syndrome. Method: Using Pubmed, Medline, and CINAHL search engines, a randomized controlled trial(RCT) researching titles such as 'metabolic syndrome', 'intervention', 'lifestyle modification', or 'community-based' were collected. A total of 16 researches were analyzed based on the guidelines of the National Cholesterol Education Program - Adult Treatment Panel(NCEP-ATP III). Results: 1) The total period of the intervention was from 12 to 24 weeks, the frequency was 3 to 5 times per week, and the duration of each session was from 45 to 60 minutes. The types of intervention included exercise, diet, and medication. Among these types, diet was performed most frequently. 2) The outcomes of the intervention was measured with physical aspects such as anthropometric measures, body composition, or biological markers. No studies have evaluated psychosocial outcomes such as quality of life. 3) In terms of effectiveness of the intervention, anthropometric indicators, body composition, or serological markers showed positive effects, whereas results on endothelial or urine indicators were inconsistent. Conclusion: Methodological research developing comprehensive therapeutic lifestyle modification programs and intervention studies are needed for patients with metabolic syndrome. In addition, effects should be evaluated with multidimensional perspectives.

  • ICT in the IOT era is the core basis of modern society. This study investigated and analyzed the recent commercialization trends of smart fashion products internationally and domestically, to utilize them as the basis of data for developing user-friendly smart fashion products that can meet the needs of consumers. Keyword research using the most representative search engines, Google and Naver was conducted for searching for various wearable items commercialized actively since 2010. The final 78 products were classified by the physical area, and the key features and benefits were analyzed. Smart fashion products were classified as four physical types for the head and face, torso, arms and hands, and ankles and feet. Smart fashion products for each body part were developed in various ways, such as hats, glasses, lenses, virtual screens, earphones, headsets, clothing, watches, wrist bands, gloves, rings, wallets, bags, anklets, shoes, socks, and insoles. The main features were music playback, bluetooth, a camera based on NFC, virtual effects, health and safety protection through measuring heartbeat and momentum, and social network sharing of all kinds of information, based on inter-working with a smartphone. These functions represent the physical, social, and emotional interactions among users and their surroundings, as well as the users, themselves. The research results are expected to be used in future studies on planning user-friendly and marketable products through in-depth analysis of the design characteristics of smart fashion products as well as consumer responses.

  • PURPOSE: The aim of this study was to review the effects of exercise intervention on blood glucose control in obese type 2 diabetic patients. METHODS: The PubMed and KERISS search engines were used and 61 papers that met the key questions were selected. RESULTS: Exercise is an effective intervention for the control of blood glucose in type 2 diabetic patients because it does not impair glucose transport in the skeletal muscle induced by muscle contractions. Insulin resistance, which is characteristic of type 2 diabetes, is caused by decreased insulin sensitivity or insulin responsiveness. Acute exercise improves the glucose metabolism by increasing the insulin-independent signaling pathways and insulin sensitivity in the skeletal muscle, and regular long-term exercise improves the skeletal muscle insulin responsiveness and systemic glucose metabolism by increasing the mitochondrial and GLUT4 protein expression in the skeletal muscle. CONCLUSION: The improvement of the glucose metabolism through exercise shows a dose-response pattern, and if exercise consumes the same number of calories, high intensity exercise will be more effective for the glucose metabolism. On the other hand, it is practically difficult for a patient with obese type 2 diabetes to control their blood glucose with high intensity or long-term exercise. Therefore, it will be necessary to study safe adjuvants (cinnamic acid, lithium) that can produce similar effects to high-intensity and high-volume exercises in low-intensity and low-volume exercises.

  • Context: Tobacco is the single largest cause of preventable death among adults globally, as it is in India. Despite this alarming situation, there is very minimal inclusion of tobacco in formal education systems, including the medical discipline, in India. Aims: The present study analyzed the extent of integration of tobacco control related content in Masters of Public Health (MPH) curricula of various institutes in India. Materials and Methods: This cross-sectional study was conducted during January 2011 to May 2011 in all colleges of the country offering a MPH course. The colleges were enlisted using various internet search engines (Google Scholar, Pubmed, Medline), other published literature and snowball technique. A 50 items semi-structured questionnaire was designed, posted and e-mailed (followed by hard copy) to the Person-In-Charge of the MPH program. Statistical Analysis: Descriptive statistics were used to profile the tobacco control content in respective institutions. All data entry and analysis was conducted using SPSS (version 16) for windows. Results: The duration of the MPH course was two years in all institutes and had accreditation with some affiliated body. Tobacco related diseases were covered under 'non communicable diseases' section by every institute. However, a mere 41.4% of institute's had faculty who had received specialized training in tobacco control. More coverage was given to health risks and effects of smoking as compared to cessation interventions (5 A's), symptoms of withdrawal and pharmacological treatments. Only 25% of institutes were in process of introducing tobacco courses into their curricula. Lack of expertise and administrative barriers were cited as perceived major problems in inclusion of tobacco control in MPH curricula. Conclusions: It can be concluded that tobacco control is not receiving adequate attention in public health curricula in India. There is a need for coordinated efforts in the area of tobacco control so as to reduce morbidity and mortality from tobacco induced diseases.

  • With the era of the 4th Industrial Revolution, the number of data-centric integrated researches increases. The integrated researches make information identification and linkage more important, so it is necessary to seek a method to efficiently manage and share academic-information for supporting the researches. Therefore, this study aims to analyze identification system and linkable information types of 12 major academic search engines and bibliographic databases(ASEBDs) in Korea and abroad and to propose a method to identify and link academic-information. The analysis was conducted 2 times, and academic-information types, searchable fields, linkable information types, used identification system were investigated. As a result, the ASEBDs link directly or/and indirectly 3~4 information types based on their own identifiers with persistent identifiers. In addition, they identify academic-information semi-automatically based on machine learning methodology and collect and manage the related data. Finally, the method for academic-information linkage was proposed in terms of practice and society: linkage based on persistent identifiers and linkage based on collaborative network of institutions.
