DNA 컴퓨팅은 분자 수준(molecular level)에서 연산을 수행한다. 따라서 일반적인 실리콘 기반의 컴퓨터에서와는 달리, 순차적인 연산 제어를 보장하기 어렵다는 특징이 있다. 그러나 DNA 컴퓨팅은 화학반응에 기초한 연산이기 때문에, 실험자가 의도한 연산을 많은 수의 분자에 동시에 적용할 수 있으므로 실리콘 기반의 컴퓨터와는 비교할 수 없는 병렬 연산을 구현할 수 있다. 병렬 연산을 구현하고자 할 때, 일반적으로 연산에 사용하는 모든 DNA 분자들을 대상으로 연산을 구현할 수도 있다. 그러나 전체가 아닌 일부의 분자들을 상대로 연산을 수행하는 것 역시 가능하며 이 때 자연스러운 방법으로 사용할 수 있는 방법이 배깅(Bagging)이나 부스팅(Boosting)과 같은 앙상블(ensemble) 계열의 학습 방법이다. 일반적인 부스팅과 달리 가중치를 부여하는 것이 아니라 특정 학습자(learner)를 나타내는 분자들을 증폭한다면 가중치를 분자의 양으로 표현하는 것이 가능하므로 분자 수준에서 앙상블 계열의 학습을 구현하는 것이 가능하다. 본 논문에서는 앙상블 계열의 학습 방법 중 특히 부스팅의 효과를 DNA 컴퓨팅에 응용하고자 할 때, 어떤 방법이 가능하며, 표현 과정에서 고려해야 할 사항은 어떠한 것들이 있는지 고려하고자 한다. 본 논문에서는 규모를 사전에 한정할 수 없는 진화 가능한 그래프 구조(evolutionary graph structure)를 학습할 수 있는 방법을 찾아보고자 한다. 진화 가능한 그래프 구조는 기존의 DNA 컴퓨팅 방법으로는 학습할 수 없는 문제이다. 그러나 조합 가능한 수를 사전에 정의할 수 없기 때문에 분자의 수에 상관없이 동일한 연산 시간에 문제를 해결할 수 있는 DNA 컴퓨팅의 장정을 가장 잘 발휘할 수 있는 문제이기도 하다.개별 태스크의 특성에 따른 성능 조절과 태스크의 변화에 따른 빠른 반응을 자랑으로 한다. 본 논문에선 TIB 알고리즘을 리눅스 커널에 구현하여 성능을 평가하였고 그 결과 리눅스에서 사용되는 기존 인터벌 기반의 알고리즘들에 비해 좋은 전력 절감 효과를 얻을 수 있었다.과는 한식 외식업체들이 고객들의 재구매 의도를 높이기 위해서는 한식 외식업체의 서비스요인, 식음료요인, 이벤트 요인 등을 강화함으로써 전반적인 종사원 서비스 품질과 식음료품질을 높이는 전략을 취해야 한다는 것을 시사해주고 있다. 본 연구는 대구 경북소재 한식 외식업체만을 대상으로 하여 연구를 실시하여 연구의 일반화와 한식 외식업체를 이용하는 이용 고객들이 한식 외식업체를 재방문하는 재구매 의도가 발생하는데 있어 발생하는 과정을 설명하는 종단적 연구를 실시하지 못한 한계점을 가지고 있다.아직 산업 디자인이 품질경쟁력에 크게 영향을 미치는 성숙단계에 이르지 못하였음을 의미한다. (2) 제품 디자인에게 영향을 끼치는 유의적인 변수는 연구개발력, 연구개발투자 수준, 혁신활동 수준(5S, TPM, 6Sigma 운동, QC 등)이며, 제품 디자인은 우선 품질경쟁력을 높여 간접적으로 고객만족과 고객 충성을 유발하는 것으로 추정되었다. 상기의 분석결과로부터, 본 연구는 다음과 같은 정책적 함의를 도출하였다. 첫째, 신상품 개발과 혁신을 위한 포괄적인 연구개발 프로젝트를 품질 경쟁력의 주요 결정요인(제품의 기본성능, 신뢰성, 수명(내구성) 및 제품 디자인)과 연계하여 추진해야 할 것이다. 둘째, 기업은 디자인 경영 마인드 제고와 디자인 전문인력 양성을, 대학은 디자인 현장 업무를 통하여 창의력 증진과 기획 및 마케팅 능력 교육을, 정부는 디자인 기술개발 및 디자인 교육지원의 강화를 통하여 각각 디자인 경쟁력$\righta

국내대학은 학령인구 감소와 등록금 동결로 재정적인 어려움을 겪고 있다. 2018년 대학기본역량진단평가를 받으면서 선택과 집중을 통한 생존전략을 모색하고, 효율적으로 대학을 운영하는 방법이 주목받고 있다. 교육서비스 품질의 향상은 대학 행정직원의 업무 몰입을 통해서 가능하며, 이는 직원 만족도의 향상을 통해 이루어진다. 대학 행정직원의 실제 만족도는 사전에 갖고 있던 일정 수준의 기대가 영향을 미친다. 본 연구에서는 사전 기대와 실제 성과의 차이인 직무기대 불일치가 전반적인 직무만족에 미치는 영향을 조사하였다. 이를 통해 지원정책의 우선순위를 제시하여 효율적인 전략수립에 도움을 주고자 한다. 남성은 여성에 비해 보수결정과정과 조직내 인간관계를 더욱 중요하게 여기고 있으며, 여성은 정년보장을 더욱 중요하게 여기고 있다. 근무기간이 짧을수록 보수결정과정, 급여의 적절성, 복지제도에서 기대불일치가 높고, 승진의 공정성에 대한 기대불일치는 낮다. 전반적인 직무만족 결과가 개인 특성별로 차이가 존재하므로 직원 지원정책 수립과정에 개인 특성을 고려한다면 제한된 재원으로 효율적인 전략을 수립할 수 있을 것이다.

According to the Library Act enacted in 1963, the national bibliography of Korea has been publishing annually since 1965. Unlike countries around the world that have been promoting the continuous development of national bibliography and service innovation, Korean national bibliography is rarely used due to service degradation and structural problems of data. The national bibliography has great significance as a symbol that reflects a country's knowledge culture, as it is a comprehensive records of publications published domestically or related to the country. This study intends to propose a data construction and operation strategy for improving the Korean national bibliography. To this end, this study (1) analyzes trends and key contents of international guidelines for national bibliography, (2) examines the meanings and sustainability of national bibliography at current information environment, and (3) suggests detailed operational strategies to improve the quality and service of Korean national bibliography. Data was collected and utilized through case studies, interviews with stakeholders including national library staffs, and literature reviews.
