Golf has emerged as one of the key leisure activities in Korea. This study examines the characteristics of golf consumption typology. A total of 256 questionnaires were collected from membership and public golf courses in the Incheon and Gyeonggi district. This study explores user satisfaction with and service at the golf course. The results of this research show that there are primary factors in user satisfaction regarding course facility, scores and operational services. Detail responses regarding these golf courses prove that the whole of the golf course, satisfaction with the course layout, landscaping and user gratification with the golf facilities are influenced by contentment with the management of the golf course. Satisfaction with scores were correlated with user contentment with the golf course. Detailed factors regarding operational services cited such aspects as ease of reservations, staff and tee time, all factors related to the smooth arrangements and progress that are influenced by operational services. This research was more concerned with course design and facility operations than marketing operations, which can satisfy users through investment in variety and expansion of the course facilities. Satisfaction in these areas is correlated to revisits and recommendations to others. The types of membership and public golf courses face difficulty in development, operation, and facilities maintenance, among other features. This paper will help separate out each quality in order to formulate difference stratagems for marketing and operation tactics in the future.

복수학위/교환학생 프로그램의 활성화로 강좌의 교수진과 학생들이 글로벌화되고 있다. 그동안 기존의 오프라인 위주의 강좌에서 벗어나 온라인 강좌나 블렌디드 학습 기반 강좌가 연구개발 되어 왔다. 하지만 기존의 연구는 대학 내에 국한되어 있어 복수학위나 교환학생 프로그램에 대한 고려는 이루어지지 않고 있다. 글로벌 강좌를 개발하고 운영하기 위해서는 비용이나 효율성 측면에서 여러 가지 어려움이 수반된다. 이를 효과적으로 해결하기 위한 방안으로 온/오프라인을 융합한 블렌디드 글로벌 강좌의 운영이 필요하며 이에 대한 연구가 시급하다. 이를 위해 본 연구에서는 블렌디드 글로벌 강좌 모형을 제시 개발하였다. 해외 석학 중심의 글로벌 강좌 개설 및 운영을 위해 블렌디드 러닝 방법을 반영하여 개설 시기와 온/오프라인 상호 유기적 관계에 따라 크게 8가지로 유형을 고안하고 이들 유형 간의 상호 비교 분석을 하였다. 본 연구에서 제안하는 블렌디드 글로벌 강좌는 글로벌시대에 적합한 인재를 대학에서 양성하는 데 적용할 수 있을 것이다.

시간경로 유전자 발현자료에 대한 본격적인 통계분석을 수행하기에 앞서 의미있는 정보를 제공하지 못할 것으로 여겨지는 유전자들은 선별하여 미리 제거함으로서 자료의 차원을 축소시킬 수 있을 뿐 아니라, 잡음이나 변이가 낮은 자료로 인한 잘못된 판단을 감소시킬 수 있다. 본 논문에서는 관측표본에 대한 백분위수 기준과 붓스트랩 표본에 대한 백분위수 기준 하에서 무 변화 패턴을 갖는 유전자들을 제거시킬 수 있는 기존의 필터링 함수들을 비교하였다. 이스트(yeast) 자료에 적용하여 두 가지 필터링 방식에 대해 가장 유사한 결과를 보인 것은 분산 함수였다.

생물학자들은 시간에 따라 발현 수준이 변화하는 유전자의 군집화를 시도하고 있다. 지금까지는 마이크로어레이 자료의 군집분석에 관한 연구의 경우 군집 방법 자체를 비교하는 연구가 주를 이루었다. 그러나 군집화 이전에 의미있는 변화를 보이는 유전자 선택에 따라 군집화 결과가 달라지기 때문에, 군집 분석에 있어서 유전자 선택 단계도 중요하게 고려되어야 한다. 따라서, 본 논문에서는 시간 경로 마이크로어레이 자료를 군집 분석하는데 있어서 유전자 선택, 군집 방법 선택, 군집평가 방법 선택 등 3가지 요인을 고려한 폭 넓은 비교 연구를 하였다.

본 연구에서는 가우시안 과정회귀방법을 소개하고 시계열 마이크로어레이 유전자 발현데이터에 대해 가우시안 과정회귀를 적용한 사례를 보이고자한다. 가우시안 과정회귀를 적합하여 로그 주변우도함수 비를 이용한 유전자를 선별방법에 대한 모의실험을 통해 민감도, 특이도, 위발견율 등을 계산하여 선별방법으로의 활용성을 보였다. 실제 효모세포주기 데이터에 대해 제곱지수공분산함수를 고려한 가우시안 과정회귀를 적합하여 로그 주변우도함수 비를 이용하여 차변화된 유전자를 선별한 후, 선별된 유전자들에 대해 가우시안 모형기반 군집화를 하고 실루엣 값으로 군집유효성을 보였다.

The course timetabling problem is a problem assigning a set of subjects to the given classrooms and different timeslots, while satisfying various hard constraints and soft constraints. This problem is defined as a constraint satisfaction optimization problem and is known as an NP-complete problem. Various methods has been proposed such as integer programming, constraint programming and local search methods to solve a variety of course timetabling problems. In this paper, we propose an iterative improvement search method to solve the problem based on constraint programming. First, an initial solution satisfying all the hard constraints is obtained by constraint programming, and then the solution is repeatedly improved using constraint programming again by adding new constraints to improve the quality of the soft constraints. Through experimental results, we confirmed that the proposed method can find far better solutions in a shorter time than the manual method.

This paper introduces a class model based on a course, Internet English, offered by an English department at a university. The course has dual purposes of developing students I English skills and Internet using skills at the same time. In support of using the Internet for language learning, the advantages of project-based language learning and constructivist learning in relation to CALL are explored. The activities in this course, which are basically project-based under the paradigm of constructivist learning perspective, are explained in detail to show the relationship between second language learning theory and teaching application. The way how the four language skills - speaking, listening, reading, and writing - are integrated in this class is described as well. Finally, judgmental evaluation of the course by the students is noted. The results show that a project-based CALL class could be a promising class model to realize an integrative, constructivist, and authentic learning.

This paper presents the approach followed to develop a course that introduces reliability into the design of power electronics converters. The course is part of the curriculum of a master of science in electrical engineering program, and it is aimed at providing reliability tools that can be used in a straightforward manner, while avoiding the mathematical intricacies. The reliability calculations are performed according to the Military Handbook 217, using the evaluation version of a commercial software package which greatly reduces the computational burden usually associated with this task. The course assessment shows that, after attending the course, students were able to improve the mean time between failures in a power-electronics converter, from a minimum of 5%, up to 100%.

This paper proposes learning modules as a kind of integrated instruction model for soft skills program outcomes to enable CEA. Learning modules consist of course learning objectives(outcomes) described in detail, learning content(elements), learning activities(teaching learning methods), evaluation methods, evaluation rubrics so that they can be evaluated based on the performance criteria of the program learning outcomes. The unit of time for the learning module is 50 minutes. If this learning module is applied, it is expected that the soft skill program outcomes can be evaluated in the technical course. As a result of the expert feasibility study, the positive answers were much higher than the negative answers in most of the questions about the composition of the learning module or the method of managing the class.

Liver is the major organ to regulate the systemic glucose homeostasis and insulin resistance. Excess energy intake leads to triglyceride accumulation in adipose tissue first and subsequent accumulation in liver, resulting in obesity and type 2 diabetes. The representative pathological animal model for obesity associated insulin resistance is a high fat diet (HFD) fed mice model. Given the essential role of liver fat accumulation in developing systemic insulin resistance in obesity, I measured the liver triglyceride contents in HFD fed mice as a function of time. As such, in this report, I show the cause and effect relationship with regard to time during a HFD feeding between a variety of factors that are related to systemic insulin resistance including glucose intolerance, plasma insulin level and inflammatory gene expression in liver and adipose tissue.
