A Design on RDF and DB Query Generator for Category Search System
Yulan Cui,Hyunsuk Hwang,Changsoo Kim 한국멀티미디어학회 2008 한국멀티미디어학회 학술발표논문집 Vol.2008 No.2
The search works are common and an essential function whether in database-based system, ontology-based system or the combination of database and ontology system. The query languages like SPARQL for RDF and SQL for database are important parts for accessing information and deciding the accuracy of results. In this paper, we design RDF and DB query generator for category search system based on the database and ontology. The RDF query generator can generate SPARQL query sentences for extracting vital resource depending on defined ontologies and given conditions. The DB query generator can generate SQL query sentences for extracting the results that the user wants using the previous step's vital resource.
Applying Spatial Analysis to Facility Searching in Underground Space
Yulan Cui,Hyunsuk Hwang,Changsoo Kim 한국멀티미디어학회 2009 한국멀티미디어학회 학술발표논문집 Vol.2009 No.1
The utilization of underground space has recently increased with the complication of road, the rise of the land price, and the development of the green technology. Underground space ranges from classical excavations to subway, underground cities, and shopping mall which there always a lot of people around. Meanwhile, various types of the facilities have rapidly grown for preparations of the increasing potential disasters. Therefore, an effective facility searching work is required. In this paper, we designed and implemented a facility information system based spatial analysis to provide convenient and easy searching work to general users who do not know much about related information of facilities. This system has advantages in avoiding fussy searching work with attributes of facilities.
Design of the Ontology Based Retrieval Engine for Managing the Public Control Points
Seonghyun Shin,Yulan Cui,Myunggil Park,Hyunsuk Hwang,Yongcheol Suh,Changsoo Kim 한국멀티미디어학회 2008 한국멀티미디어학회 국제학술대회 Vol.2008 No.-
The spatial information is being more widely used with the development of ubiquitous society and the effective management of control points which are basis of the spatial information is required. The existing management system supports key words and categorized search. However, the ontology-based retrieval system is not only dealing with complex queries but also increasing effective business and convenience. Therefore, this paper proposes the design of the ontology-based retrieval engine including the function of intelligent and personalized search. Our searching engine is able to be applied to current management systems of control points and PDA and Web-based information systems related with control points.

The relationship between the single-nucleotide polymorphism (SNP) of ERBB4 gene in the microRNA binding site and the susceptibility of endometrial carcinoma was investigated. A total of 1671 patients with endometrial carcinoma and 1796 healthy controls were enrolled in the study. Genotypes of the ERBB4 gene in the microRNA binding sites at rs1595066 and rs16845990 were then determined using the TaqMan SNP method. The endometrial carcinoma patients and healthy controls showed significant differences in three ERBB4 gene genotypes in the microRNA binding site at rs1595066 (P = 0.044), whereas no difference was observed at the rs16845990 site (P = 0.313). Carriers of the AG and AA genotypes at the rs1595066 site showed lower risk of endometrial carcinoma than the carriers of the GG genotype [odds ratio (OR) = 0.82 and 95 % confidence interval (CI) = 0.70–0.94, and OR = 0.74 and 95 % CI = 0.56–0.94, respectively]. Stratified analysis showed that this protective effect was significant in subjects older than 50 years and those without a history of benign endometrial disease or a family history of cancer. The polymorphism of rs1595066 G[A in the microRNA binding site of the ERBB4 gene is possibly associated with the reduction of endometrial carcinoma risk.
Proteomic Analysis on Exosomes Derived from Patients’ Sera Infected with Echinococcus granulosus

Cystic echinococcosis (CE), a zoonotic disease caused by Echinococcus granulosus at the larval stage, predominantly develops in the liver and lungs of intermediate hosts and eventually results in organ malfunction or even death. The interaction between E. granulosus and human body is incompletely understood. Exosomes are nanosized particles ubiquitously present in human body fluids. Exosomes carry biomolecules that facilitate communication between cells. To the best of our knowledge, the role of exosomes in patients with CE is not reported. Here, we isolated exosomes from the sera of patients with CE (CE-exo) and healthy donors and subjected them to liquid chromatography-tandem mass spectrometry analysis. Proteomic analysis identified 49 proteins specifically expressed in CE-exo, including 4 proteins of parasitic origin. The most valuable parasitic proteins included tubulin alpha-1C chain and histone H4. And 8 proteins were differentially regulated in CE-exo (fold change>1.5), as analyzed with bioinformatic methods such as annotation and functional enrichment analyses. These findings may improve our understanding about the interaction between E. granulosus and human body, and may contribute to the diagnosis and prevention of CE.
