  • This paper uses our proposed model for connecting ubiquitous physical objects over the web using URI, while utilizing the already developed frameworks, for ubiquitous service discovery like JINI, UPnP, and RDF/OWL for semantic web. By using this proposed scheme, we have presented architecture of a service oriented modular distributed ubiquitous middleware i.e. MDMA

  • A track type underwater construction robot(URI-R) which can trench on seabed is being developed by Korea Institute of Ocean Science & Technology. During the underwater trenching work, the robot is exposed high intensive noise and vibration so the underwater localization signal may not be obtained properly by the acoustic tracking system. Therefore it is necessary to research about continuous localization even though the measured position signal comes in intermittently. In this paper, the experiments were carried out on land to simulated the underwater operating environment characteristics. To estimate its position, inertial navigation system and global navigation satellite system are used. The effects of the period variation while localizing is investigated by the experiments, and the application for URI-R is proposed.

  • This study was done to determine the effect of additional nitrogen fertilization on the yield and quality of the Korean wheat cultivars Keumkang, Jokyoung, Baegjoong, Sooan, Uri and Goso. Different levels of nitrogen applications (109, 82, 55, 41, and 27 kg/ha) were applied to six cultivars. The results show that the yield and protein contents were increased in all tested cultivars. The grain yields of the cultivars Keumkang, Jokyoung, Baegjoong and Sooan were greatly increased in the case of double fertilization treatments. Moreover, Uri and Goso had greatly increased yields by the additional fertilization at a 50% rate compared with korea wheat standard fertilization rate. A significantly higher yield was observed in Uri. Baegjoong was the highest yielding cultivar among the tested cultivars with the additional nitrogen fertilization. As the fertilization was increased up to double the fertilization treatment, the yield of Baegjoong also showed a constant increase. Positive correlations were found between the nitrogen fertilizer application levels and the protein contents of the grain in all the cultivars except for Uri, and among these, Jokyoung had a most significant correlation between the nitrogen fertilizer application level and the increase in its protein contents. Keumkang had the highest protein contents and highest increase in the protein content change according to the amount of nitrogen application. However, amylose, damaged starch and ash contents were not significantly changed by the different levels of nitrogen applications.

Research on Minimizing Access to RDF Triple Store for Efficiency in Constructing Massive Bibliographic Linked Data (극대용량 서지 링크드 데이터 구축의 효율성을 위한 RDF 트리플 저장소 접근 최소화에 관한 연구)

  • In this paper, we propose an effective method to convert and construct the MEDLINE, the world's largest biomedical bibliographic database, into linked data. To do this, we first derive the appropriate RDF schema by analyzing the MEDLINE record structure in detail, and convert each record into a valid RDF file in the derived schema. We apply the dual batch registration method to streamline the subject URI duplication checking procedure when merging all RDF files in the converted record unit and storing it in a single RDF triple storage. By applying this method, the number of RDF triple storage accesses for the subject URI duplication is reduced from 26,597,850 to 2,400, compared with the sequential configuration of linked data in units of RDF files. Therefore, it is expected that the result of this study will provide an important opportunity to eliminate the inefficiency in converting large volume bibliographic record sets into linked data, and to secure promptness and timeliness.

  • Objectives : To explore the factors influencing antibiotics prescription by primary health physicians for acute upper respiratory infections(URI). Methods : We performed a survey of 370 primary health physicians randomly sampled in April, 2003. The questionnaire consisted of a prescription on the scenario of acute bronchitis case, along with opinions and reasons for prescribing antibiotics on URI. Results : We found that 54.7% of the physicians prescribed antibiotics on the example case of acute bronchitis which is known as not needing antibiotics. Female physicians and ENT physicians had a greater tendency to prescribe antibiotics. The factors influencing antibiotics prescription on URI were the belief about the effectiveness of antibiotics, preference for their own experiences rather than clinical guidelines, perception of patients' expectations, and perception of competitive environment. The prescription of antibiotics in the example case was affected by how much they usually prescribe antibiotics (OR=2.400, 95% CI=1.470-3.917) and the physicians who thought that antibiotics were helpful for their income prescribed antibiotics more than others (OR=6.773, 95% CI=1.816-25.254). Conclusion : These findings demonstrated that the false belief on the effectiveness of antibiotics, patient's expectation of medication and fast relief of symptoms, and perception of competitive environment all affected the physicians prescription of antibiotics on URI. It may help to find barriers to accommodate scientific evidence and clinical guidelines among physicians and to specify subgroups for education about appropriate prescription behaviors.

  • Objectives : This study examined the factors influencing variation by local areas of antibiotics prescription rate in upper respiratory infections (URI) according to the public reporting. Methods : We used the National Health Insurance Claims Data which the clinics claimed for URI (Korean Standard Classification of Disease, J00 ~ J06) in ambulatory care. The period of analysis was from the first quarter (from January to March) of 2005 to the first quarter of 2007. The number of samples was total 242 local areas that included all clinics (N = 7,942), which prescribed antibiotics for URI in ambulatory care. Results : None of the demographic and socioeconomic characteristic indicators was statistically significant. Among the provider factors, An increase in number of doctors and the average annual antibiotics prescription rate (from 2003 to 2004) for URI by local area were significantly related to an increase of antibiotics prescription rate according to the public reporting. And an increase in number of pediatric clinics, the proportion of clinics less than 5 years since has opened and the average annual fluctuation of antibiotics prescription rate (from 2003 to 2005) were significantly related to a decrease in antibiotics prescription rate by local area according to the disclosure of information. Conclusions : According to the public reporting, the antibiotics prescription rate in clinics had decreased sharply. However, the reduction of antibiotic prescription rate varied in different local areas. The factors influencing variation by local areas in antibiotics prescription rate can be used for establishing effective strategies to reduce variation by region in antibiotics prescription rate.

  • In order to provide VoIP service that using SIP on the Internet, users must register their current location to receive call from other cal]or. 13y using REGISTER method, users register his or her SIP URL address and currently contactable addresses to registrar server. The registered addresses are not only SIP URI but also mai]to, http, tel, and so on. In these procedures, we must consider authentication mechanism whether he/she has authority to handle the record or not. In this paper, we will briefly describe authentication mechanism that used in SIP and design of registrar server that support the 3rd party registration.
