유비쿼터스 환경에서 다양한 개인화 서비스에 적용하기 위한 사용자 모델링의 일반화 방법론
이주연(Juyeon Lee),이성진(Seongjin Lee),이수원(Soowon Lee) 한국정보과학회 2006 한국정보과학회 학술발표논문집 Vol.33 No.2B
최근 연구가 활발히 진행되고 있는 ‘유비쿼터스’라는 새로운 패러다임은 기존보다 더욱 많은 컴퓨팅 자원을 이용하여 사용자의 편의를 지원하는 것을 그 목표로 하고 있다. 유비쿼터스 컴퓨팅 환경에서 사용자를 지원하기 위한 대표적인 예로 개인화 서비스를 들 수 있으며, 개인화 서비스는 사용자에 대한 모델링이 필수 요소가 된다. 개개인의 행동 패턴 혹은 선호도 정보로 구성된 사용자 모델은 다양한 개인화 서비스의 원활한 지원을 위해 지금까지 유용하게 사용되고 있지만, 기존의 사용자 모델은 각 서비스가 개발될 때, 그 서비스에 적합한 형태로 매번 설계되어야 하는 문제점을 지닌다. 본 논문에서는 이러한 문제점을 해결하고자, 사용자 모델을 구성하는 정보들을 분석하여, 모델 설계에 필요한 일반화된 입력 패턴들을 도출하고, 도출된 패턴들을 바탕으로 더욱 쉽고 빠르게 사용자 모델을 생성할 수 있는 방법을 제안한다.

Objective: We evaluated the clinical significance of clinical factors and hematological parameters as prognostic factors in patients with locally advanced cervical cancer (LACC) who received definitive concurrent chemoradiotherapy (CCRT). Methods: We retrospectively analyzed 125 patients with LACC (FIGO stage IIB to IIIB) who received definitive CCRT. Clinical factors and hematological parameters, including neutrophil-to-lymphocyte ratio (NLR) were assessed pre- and post-CCRT. Neutrophil-to-lymphocyte ratio (NLR) was calculated by dividing absolute neutrophil counts by absolute lymphocyte counts. Tumor size was determined by measuring the largest tumor diameter in MRI or CT images. Univariate and multivariate analysis for disease-free survival (DFS) and overall survival (OS) were performed using clinical factors and hematological parameters. Results: Disease recurred in 46 (36.8%) patients, and 24 patients (19.2%) died. On multivariate analysis, tumor size, paraaortic lymph node metastasis, post-treatment NLR, NLR (pre-treatment NLR/post-treatment NLR) and PLR (platelet-to-lymphocyte ratio) (pretreatment PLR /posttreatment PLR) were significant prognostic factors for DFS. Among them, only post-treatment NLR and tumor size were a significant prognostic factor for OS (p<0.001). Combination of tumor size and post-treatment NLR were significant prognostic factor for DFS and OS. Patients with large tumor size and elevated post-treatment elevated NLR were shown poor prognosis. Conclusion: Combination of tumor size and post-treatment NLR may serve as a prognostic indicator in patients with LACC who received definitive CCRT.

Purpose: The purpose of this study was to develop an integrated nursing practicum education matrix based on the learning outcomes of each stage. Methods: In this Delphi technique study, 10 experts, consisting of six professors and four nurses, participated in the development of the matrix. The first step was an in-depth review for the composition of the questionnaire and the second step was the Delphi technique. The Delphi survey was conducted two times in order to complete the components of the matrix. The survey data was analyzed for statistical averages and standard deviations to decide the order of priority. Results: According to each stage (i.e. fundamental stage, competent stage, and proficient stage), the matrix was composed of education contents, methods, evaluation methods, and curriculum outcomes. Conclusion: The integrated nursing practicum education matrix of Y University was completed. The developed matrix will result in a reduction in the gap between nursing education and clinical practice and an improvement in nursing competency.
Identification of quantitative trait loci for fusarium wilt resistance in radish (Raphanus sativus)
Juyeon Jung,Jaehwang Ryu,Yeonok Choi,Young-Pyo Lee 한국육종학회 2015 한국육종학회 심포지엄 Vol.2015 No.07
Radish, Raphanus sativus(2n = 18), belonging to the brassicaceae family, is herbaceous plant with 1-2 years life cycle. It is cultivated worldwide for producing leafy and root vegetables. Although an economically important crop, the genetics of yield and quality traits, disease resistance are not well-studies. The major purpose of this project is development of molecular breeding technology in radish. In this project, quantitative trait loci (QTL) for Fusarium wilt resistance of radish were analyzed. To identify QTL, genetic linkage map of radish was constructed using F2 mapping population derived from a cross between two inbred lines, “DB01” (resistant) and “DB05” (susceptible). A total 319 markers have been mapped into nine linkage groups, covering 639.3cM with an average distance of 2cM between loci. QTL mapping detected 2 loci conferring Fusarium wilt resistance. Two QTLs were located on LG3 and LG7, respectively. The QTL of LG3, flanked by EAGGMCT6 and WALK500 marker, exhibited a LOD value ranging from 2.3 to 8.7, and the R2 (Phenotypic variations) ranging from 28 to 48% in four tests. This QTL was named qYR1. The QTL of LG7, flanked by EACCMCAC-202 and DCJ14-390 marker, exhibited a LOD value ranging from 6.2 to 10.6, and the R2 ranging from 42 to 55% in four tests. This QTL was named qYR2. The results of the QTL analysis may be useful in marker-assisted selection (MAS) of Fusarium wilt resistant radish cultivars.
School Counselors’ Recognition of the Ultra-High Risk for Psychosis

The ability to identify students at ultra-high risk (UHR) for psychosis in school settings is crucial for enabling appropriate referral to a clinician and positive therapeutic results. The aim of this study was to examine school counselors’ recognition of the diagnosis and appropriate treatment recommendations for students at UHR for psychosis. In total, 132 school counselors completed surveys, including questions relating to a vignette about a student at UHR for psychosis. In total, 12.4% of the sample provided the correct diagnosis, much lower than that for other schizophrenia spectrum disorders and non-psychotic disorders, including depressive disorder. Although most school counselors preferred psychiatrists as the first-line treatment for students at UHR for psychosis, counseling centers were also mentioned as potential treatment options. In terms of medication, antipsychotics were preferred over other medication classes. It is necessary to design appropriate educational and training programs for school counselors to promote identification and effective referral of those at UHR for psychosis.

We investigated the association between problematic internet use (PIU) and post-traumatic stress disorder (PTSD) symptoms in children and adolescents in South Korea. A cross-sectional survey was administered to community students who attended primary, secondary, and high schools in the Jindo area 1–2.5 months after the Sewol ferry disaster. Of the 1,744 respondents, 392 students who were exposed to the disaster, witnessing the rescue work directly, were evaluated. PTSD symptoms were measured using the University of California Los Angeles Post-traumatic Stress Disorder Reaction Index (UCLA PTSD-RI). The severity of impairment caused by excessive internet use was evaluated using Young’s Internet Addiction Test. The Center for Epidemiological Studies Depression Scale (CES-D) and State Anxiety Inventory for Children (SAIC) were also used. Logistic regression analysis revealed that PIU was significantly and independently associated with a high level of PTSD symptoms. Our findings suggest that children and adolescents with PIU require intensive follow-up and special care to prevent the development of PTSD symptoms following a disaster.
