Toward High Utilization of Heterogeneous Computing Resources in SNP Detection
임명은,김민호,정호열,김대희,최재훈,최완,이규철 한국전자통신연구원 2015 ETRI Journal Vol.37 No.2
As the amount of re-sequencing genome data grows, minimizing the execution time of an analysis is required. For this purpose, recent computing systems have been adopting both high-performance coprocessors and host processors. However, there are few applications that efficiently utilize these heterogeneous computing resources. This problem equally refers to the work of single nucleotide polymorphism (SNP) detection, which is one of the bottlenecks in genome data processing. In this paper, we propose a method for speeding up an SNP detection by enhancing the utilization of heterogeneous computing resources often used in recent high-performance computing systems. Through the measurement of workload in the detection procedure, we divide the SNP detection into several task groups suitable for each computing resource. These task groups are scheduled using a window overlapping method. As a result, we improved upon the speedup achieved by previous open source applications by a magnitude of 10.

스포츠 스폰서십에 대한 소비자 반응 : 인지된 스폰서 노력의 조절효과
임명서,박경배 한국상업교육학회 2013 상업교육연구 Vol.27 No.5
본 연구는 설득지식모델의 관점에서 개인차 변수인 인지된 스폰서 기업의 노력과 상황적 변수로 서의 스폰서십 조건이 소비자의 스폰서에 대한 태도에 미치는 영향을 검증하는 것을 목적으로 한 다. 다중회귀분석 결과 인지된 스폰서 기업의 노력은 기업의 규모(대기업/중소기업), 마케팅 투자(평 균이상/평균), 스폰서 후원종목의 인기도(인기/비인기) 각각과 유의한 상호작용 효과를 보여주었다. 이에 인지된 노력과 기업의 규모, 마케팅 투자, 스폰서 후원 종목에 따른 공변량분석을 실시하였다. 분석결과 인지된 스폰서의 노력이 높을수록 스폰서 태도에서 더 호의적인 결과가 나타났다. 상호작 용효과에서는 마케팅 투자가 평균이상인 조건에서 인지된 노력의 수준이 높을 때 더욱 호의적인 스 폰서 태도가 나타났다. 스폰서 후원 종목에 있어서는 비인기종목에 대한 후원이면서 인지된 노력이 높을 때 더욱 호의적인 스폰서 태도가 나타났다. 이와 같은 결과를 토대로 기업이 효과적인 스폰서 십을 수행하기 위한 이론적, 실무적 시사점을 제시하였다. In this study, the sponsor attitude of consumers according to perceived effort as the individual differences variable in terms of persuasion knowledge model and the sponsors sponsorship conditions as the contingent variables has been verified. Firstly, multiple regression analysis revealed significant interaction effect with the perceived sponsor effort and each kind of contingent variables such as the size of the company(big/small), marketing investment(above average/average)and sponsored event(popular/unpopular). Secondly, interaction effect analysis was perform with perceived sponsor's effort and contingent variables according to analysis of covariance. As the results of the main effects, the higher the perceived effort showed more favorable attitude to sponsor. The analysis for interaction effect with perceived effort and marketing investment showed that higher perceived effort had more favorable attitude than lower perceived effort, when marketing investment is greater than the average. As the interaction effect between perceived effort and sponsored event, when less popular event, the higher perceived effort showed more favorable attitude than popular event. Based on these results, theoretical and practical implication are discussed.

F-124 The Relationship between the change of lung function and dietary intake
임명남,김우진,이상아,홍윤기 대한결핵 및 호흡기학회 2016 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.121 No.-
Introduction: Dietary intake has an effect on pulmonary function. High dietary intake is positively associated with lung function and is associated with improved lung function. We assessed the relationship between the change of lung function and dietary intake in a cohort of subjects in Korea. Methods: Surveys for this cohort study were conducted in the dusty area in Korea from 2012. At baseline and at 1-year follow-up, lung function was measured, dietary data were obtained using 24-hour recall method. The change of lung function was calculated as absolute change. The change of lung function divided into two groups (Up and Down change group) according to cutoff=0. Each dietary component was categorized into tertiles. We investigated the association between the change groups of lung function and dietary intake by multivariate logistics analysis after controlling for sex, age, BMI, energy intake (kcal/day). Results: A total of 234 subjects were followed for 1 year. After adjustment for covariates, the up group of lung function was significantly associated with intake of protein (OR=3.348, 95% CI: 1.123-6.817), LIPID (OR=2.979, 95% CI: 1.410-6.296) at 1-year follow-up. Lung function increase was highest for the upper tertile. The change in lung function was not significantly associated with dietary intake at baseline. Conclusions: There was a significant relationship between the change of lung function and dietary intake at 1-year follow-up in this cohort. These results suggest that high dietary intake was positively associated with lung function.

체육교육실기 수업구조 변화에 따른 초등 예비교사의 경험과 의미
임명재 한국초등체육학회 2017 한국초등체육학회지 Vol.23 No.2
본 연구의 목적은 교육대학에서 운영된 체육교육실기 수업구조 변화에 따른 초등 예비교사의 경험과 의미를 탐색하는 데 있다. 본 연구에서는 인터뷰와 연구참여자의 체육일기를 통해 자료를 수집하였고, Spradley(1979)가 제안한 영역 분석과 분류 분석을 토대로 분석한 결과는 다음과 같다. 첫째, 연구참여자들은 체육교육실기 강좌를 통해 ‘이해’의 과정에서 통합적 목표의 형성, ‘체험’의 과정에 대한 어색함과 반가움, ‘소통’의 과정에서 교수자와 학습자 간의 긍정적 관계 형성 등이 도출되었다. 둘째, 연구참여자들은 체육교육실기 강좌를 통해 체육수업 운영의 자신감 형성, 학생을 가르치는 교수관 형성 그리고 ‘좋은 수업’에 대한 기준을 형성 하는 등의 교육적 의미를 도출하였다. 논의에서는 연구참여자들의 교육적 경험과 의미 그리고 체육실기 강좌를 통한 성장과 변화를 선행연구와의 관계성 속에서 분석하고 해석하였으며 향후 체육교육실기 강좌의 운영 방안을 제시하였다. 이 연구는 교육대학의 체육교육실기 강좌의 경험과 의미를 교육적 시각에서 바라보고, 통합적인 체육교육실기 운영 방안을 설계하는 데 도움이 될 것이다. The purpose of this study was to investigate pre-school elementary school teacher’s experience and significance on the structural change of practical training in physical education at university of education. Data were collected through interview and study participants’ physical education diary. The results of analysis based on domain analysis and taxonomic analysis suggested by Spradley(1979) are as follows. First, the study participants presented the development of formation of integrated goals in the course of understanding, the awkwardness and joy of the experience and establishing positive relationships between learners and learners in the course of communication through the course of practical training in physical education as the details of experience. Second, the study participants deduce the educational significance such as building self-confidence in conducting a physical education class, developing a teaching perspective to teach a student, and setting the standard for ‘good class.’ In the discussion, this study analyzed and interpreted educational experience and significance and growth and change through the course of practical training in physical education in relation to precedent studies, and presented a scheme of running a course of practical training in physical education in the future. This study will be helpful in seeing the experience and significance of course of practical training in physical education at university of education from the educational point of view, and designing a scheme of conducting the integrated practical training in physical education.
