        온톨로지 기반 대용량 코호트 DB 검색 시뮬레이션

        송주형,황재민,최정석,강상길,Song, Joo-Hyung,Hwang, Jae-min,Choi, Jeongseok,Kang, Sanggil 한국시뮬레이션학회 2016 한국시뮬레이션학회 논문지 Vol.25 No.1

        Many researchers have used cohort DB (database) to predict the occurrence of disease or to keep track of disease spread. Cohort DB is Big Data which has simply stored disease and health information as separated DB table sets. To measure the relations between health information, It is necessary to reconstruct cohort DB which follows research purpose. In this paper, XML descriptor, editor has been used to construct ontology-based Big Data cohort DB. Also, we have developed ontology based cohort DB search system to check results of relations between health information. XML editor has used 7 layered Ontology development 101 and OWL API to change cohort DB into ontology-based. Ontology-based cohort DB system can measure the relation of disease and health information and can be used effectively when semantic relations are found. We have developed ontology-based cohort DB search system which can measure the relations between disease and health information. And it is very effective when searched results are semantic relations. 코호트 DB(DataBase)를 이용하여 질병 발생 예측 및 확산을 추적하는 많은 연구가 진행되고 있다. 코호트 DB는 대용량의 질병 및 건강정보가 단순한 개별적인 DB 테이블의 집합으로 구성되어있어 연관관계 검색을 위해서는 코호트 DB를 연구 목적에 맞게 재구성하는 작업이 필요하다. 본 논문에서는 대용량 코호트 DB를 온톨로지 기반으로 구축하기 위해 XML descriptor, editor를 이용하였다. 또한, 원활한 연관관계 검색결과 확인을 위해 온톨로지 기반의 코호트 DB 검색 시스템과 UI를 개발하였다. XML editor에서는 코호트 DB를 온톨로지로 구성하기 위해 7단계로 구성된 Ontology development 101 방법론과 OWL(Ontology Web Language) API를 이용하였다. 이와 같은 온톨로지 기반 코호트 DB 검색 시스템은 질병 및 건강정보의 연관성을 측정하고 의미적인 연관관계를 검색 시 효과적으로 활용 가능하다.

        호텔 직원의 커뮤니케이션 만족, 조직후원인식, 집단응집성 그리고고객지향성 간의 구조적 관계에 관한 연구

        송주형(Joo Hyung Song),김성혁(Sung Hyuk Kim),김용일(Yong Il Kim) 한국호텔외식관광경영학회 2014 호텔경영학연구 Vol.23 No.2

        The purpose of this study was to examine, in a service context, construct validity of the relationship between 4variables: communication satisfaction of the hotel staff in an organization; perceived organizational support; organization cohesiveness and customer orientation. This research, in order to achieve its goals, has established hypothesis with theoretical background and analyzed it with actual examination. The examination in this research was carried out for about a month from 15th of Aug. 2012 to 15th of Sep. 2012. A total of 350 surveys were distributed. 320 of them were collected and 282 were used for analysis. The Results are presented as follows. Firstly, four factors for the communication satisfaction were extracted such as ``communication between colleagues``, ``communicational atmosphere``, ``communication with manager layer``, ``communication both inside and outside the department``. Second, communicational atmosphere had the most positive effect on perceived organizational support followed by communication both inside and outside the department, communication between colleagues, communication with manager layer. Third, communication between colleagues had the most significant effect on organization cohesiveness followed by communication with manager layer. Fourth, perceived organizational support ad a positive effect on organization cohesiveness. Finally, perceived organizational support and organization cohesiveness had effects on customer service orientation. The results reveal that the effect of satisfaction in communication hotel staff have are interlinked with perceived organizational support and organization cohesiveness, which in turn, will have direct impacts on customer service orientation.

        신이식 후 발생한 Posttransplant Lymphoproliferative Disease

        변승운 ( Seung Woon Byun ),박혜원 ( Hye Won Park ),송주형 ( Ju Hyung Song ),오지선 ( Ji Seon Oh ),김은희 ( Eun Hee Kim ),허주령 ( Joo Ryung Huh ),서철원 ( Cheol Won Suh ),박수길 ( Su Kil Park ) 대한신장학회 2006 Kidney Research and Clinical Practice Vol.25 No.5

        Posttransplant lymphoproliferative disorders (PTLD) is an infrequent but serious complication of transplantation. Previous studies have suggested the terms of reference, early PTLD (referring to PTLD that occurs within 1 year of transplantation) and late PTLD (PTLD that occurs after 1 year). Early PTLD generally involves a single organ or nodal region and often responds favorably to a decrease in immunosuppression. Late PTLD tends to be disseminated, responds less frequently to a decrease in immunosuppression, and has a dismal prognosis. We encountered a diffuse large B-cell lymphoma in a 44-year-old man who underwent kidney transplantation over 10 years ago, in 1995. In situ hybridization for Epstein-Barr virus showed positive results in tumor cell. With decreased immunosuppressants and chemotheraphy, he is currently in complete remission.

        폐타이어로 성형제조된 부정형 과립담체에 부착된 미생물의 측정방법

        박종웅,송주형 대한상하수도학회 2003 상하수도학회지 Vol.17 No.2

        This study was carried out to know the physicochemical properties and determine the measurement method of attached biomass in irregular shape granular (ISG) media molded with waste tire. The size of ISG media and specific surface area were Φ4-10㎜ and 0.00412㎡/g, respectively. The using of pretreatment agents as 0.8N CuSO_4-0.7N Sulfamic acid was proper to prevent self-oxidation of attached biomass on ISG media. The detaching method of attached biomass in ISG media was suitable for conducting ultrasonic and alkali treatment at the same time. The optimum alkali concentration and washing time were 0.125N NaOH and 120min, respectively. Finally, it was concluded that the result of this study could be establishing as a measurement method of attached biomass on ISG media molded with waste tire.
