In this paper, we introduce the concept of fuzzy ${\gamma}$-quasi open sets which are generalizations of fuzzy ${\gamma}$-open sets, and obtain some basic properties of such fuzzy sets. Also we introduce and study the concepts of fuzzy ${\gamma}$-quasi continuous mapping and fuzzy ${\gamma}$-quasi open(closed) mapping.

The aim of this article is to introduce hesitant fuzzy paraopen and hesitant fuzzy mean open sets in hesitant fuzzy topological spaces. Moreover we investigate and extend some properties of hesitant fuzzy mean open with hesitant fuzzy paraopen, hesitant fuzzy minmimal open and maximal open sets in hesitant fuzzy topological spaces.

The purpose of this research is to find the effect of the lesson using open-inquiry report Lubric on open-inquiry standard and science process skill; to find the change of cognition on open-inquiry for elementary school 5th grade students. Two classes (elementary school 5th grade) were selected which located in a small and medium-sized city for this research and they were separated as an experimental group and a comparative group. Open-inquiry lesson was done by referring teaching method which introduced through the curriculum. The procedure was understanding about open-inquiry, making open-inquiry subject, planning, and performing inquiry, mid-term, performing inquiry, making a report, presentation, and evaluation. Open-inquiry report Lubric which developed by Sook-Kyung Kim et al. (2010) was provided to the experimental group. Comparative group was instructed by using open-inquiry report which introduced to the elementary school 5th grade science text book. Interview paper was developed in order to check out the effect of the research by using a test paper of science process skill. The following could be found out through the research. After open-inquiry lesson, 10 open-inquiry reports(5 reports from experimental group, 5 reports from comparative group) have been drawn at random as samples from the total 62 sets (30 reports from experimental group, 32 reports from comparative group) and evaluated by a researcher and two elementary school teachers who have master degree. The reliability of the 3 scorers was 0.923 of mean correlation coefficient. And then the researcher evaluated all open-inquiry reports. The average score of open-inquiry report was 66.78 for experimental group, 54.27 for comparative group, respectively. And there was a significant difference at p<0.05 level as a result of the t-test. The experimental group rated high at p<0.05 level according to the analysis of post-science process skill test. According to the result of survey, both experimental group and comparative group had understood open-inquiry activity. It was especially rated high for experimental group on understanding scientific inquiry process, interest and satisfaction in open-inquiry and re-participation rate. By interviewing experimental group, it is recognized that the students utilized Lubric very well through the overall process. Finally, self-evaluation was done during open-inquiry activity and it was reported that the students gained more knowledge about science and changed to positive about science. As a result, the lesson using open-inquiry report Lubric was effective for students to improve writing skill of an open-inquiry report and science process skill and finally changed the cognition to positive about open-inquiry lesson.

On this research we investigated variables affecting university students' time management and verify relationship between the time management and life satisfaction. 438 students at Korea National Open University in Seoul were questioned through questionnaires composed of 47 questions. Data was analyzed by t-test, one-way ANOVA, Duncan's multiple range test and Person's correlation. The variables affecting time management were religion(those who believe in organized religion vs. those who do not), individual income, family income, teaming experiences for time management and reading books related to time management. fender, age, marriage status and occupation didn't affect the time management of students. The relationships between time management and life satisfaction showed a little positive relation. Some proposals for future researches and practices are given.

We propose a parallel mesh smoothing algorithm using graph coloring and OpenMP library for shared memory many core computer architectures. The proposed algorithm partitions a mesh into independent sets and performs a parallel mesh smoothing using OpenMP library. We study the effect of using various graph coloring and color reordering algorithms on the efficiency of performing the proposed parallel mesh smoothing algorithm. We also investigate the influence of using various OpenMP loop scheduling methods on the parallel mesh smoothing efficiency.

Purpose: The purpose of this study was to compared the muscle activities of vastus medialis, vastus lateralis, rectus femoris in open kinetic chain and closed kinetic chain. Methods: Subjects of the study were 30 adults students. They were divided into 2 group, one for open kinetic chain and other for closed kinetic chain of extension, flexion, the maximum extension for vastus medialis, vastus latarealis, rectus femoris muscle activation. Results: Rectus femoris increased open kinetic chain group about all posture and vastus medialis increased open kinetic chain group about the maximum extension and flexion. and vastus lateralis increased open kinetic chain group about the maximum extension and flexion. Conclusion: Muscle activation are at the highest with the open kinetic chain in vastus medialis, vastus lateralis, rectus femoris. probably steady exercise thinked for open kinetic chain and closed kinetic chain.

The recent spread of smart devices has led to creating a variety of services based on the smart device, and the needs for the user-centric services that fit the individual users according to their situations and characteristics are increasing. However, current services can not fulfil the individual requirement of individual user, because these services are intended for unspecified individual. This paper, as a key technology of automatic user-centric service mash-up considering the situation of individual user, investigated the similarity comparison method between the Open API parameters by calculating the amount of mutual information of the parameters extracted from the Open API documents.

본 논문에서는 OpenCV를 이용한 영상처리 작업환경에서 영상처리 결과에 따라 마커를 기반으로 한 복잡한 형태의 3D 애니메이션 객체를 띄우기 위해 사용되는 증강현실 라이브러리(ARToolkit, OpenVRML)를 함께 사용하는 시스템을 제시하였다. OpenCV 라이브러리와 증강현실 라이브러리는 카메라로부터 이미지를 얻어오기 위한 함수 및 가져온 이미지 타입이 다르고 각각의 라이브러리에 맞게 이미지를 처리하기 위한 설정 및 최종적으로 디스플레이 하기 위한 일련의 과정에 있어서 호출되는 모듈들이 상이하였다. 또한 ARToolkit내에서도 보다 복잡한 3D객체의 렌더링을 수월하게 하기 위한 OpenVRML 기반 렌더링과 개발자가 원하는 렌더링을 손쉽게 수행할 수 있는 OpenGL 기반 렌더링과의 병렬적인 연동에 있어서 두 라이브러리를 사용하는 프로젝트의 카메라 및 렌더링 설정과 렌더링 처리 절차에 차이가 있어 두 프로젝트의 기능별 모듈을 하나로 통합하였다. 그리고 영상처리 라이브러리의 이미지 처리에 대한 모듈을 전체 시스템의 처리 순서에 맞게 알맞은 함수들로 배정하여 이 함수 내에서 추후 개발자가 개발한 시스템에 맞게 직접 편집하여 활용할 수 있도록 하였다.
