Recently, the use and application of computer graphics in the mobile and ubiquitous environment are growing. Real-time rendering and modeling for computer graphics are due to system performance, there're lots of limitation in lower system such as PDA and cell phone etc. Therefore, we suggested the intelligent Serving Rendering Middleware which is to provide adaptation service of computer graphics contents fit to user's environment real-time whatever environment the users are in. The Service Rendering Middleware needs multi-level configurations and applications, so, in this paper we propose multi-level algorithm to decide adaptation levels are deal with separately according to device performance.

스마트폰과 스마트TV와 같은 다양한 콘텐츠 소비 단말들이 급속히 보급되는 최근의 IT환경에서는 콘텐츠 제작, 유통, 소비에 있어서 예전과는 다른 패러다임을 요구하게 되었다. 예를 들어 각기 다른 해상도, 연산량, 사용자환경 등의 다양한 조건들에 대한 고려가 중요한 문제로 부각되고 있다. 이를 해결하고자 단일 서비스 콘텐츠 패키지로 여러 단말들에게 적응적인 서비스를 제공하는 Scalable Application Description Language(SADL)에 기반한 스케일러블 어플리케이션 프레임워크가 제안되었다. 본 논문에서는 이러한 스케일러블 어플리케이션 프레임워크에서 적응형 서비스 콘텐츠를 쉽게 생산하고 패키징 할 수 있도록 이클립스 공개소스 플랫폼 기반의 저작도구를 제안 및 개발하였다. 개발한 저작도구는 유지 보수 및 확장성을 고려하여 모델-뷰-컨트롤러에 기반한 Graphical Editing Framework(GEF)를 이용했다. 제안하는 저작도구는 다양한 운영체제에서 작동하며, 유지보수 및 확장성이 우수하다. 또한 서비스 콘텐츠 개발을 위해 이클립스 플랫폼이 지원하는 다양한 플러그인 도구들을 그대로 활용 가능하다는 장점을 갖는다. 뿐만 아니라 본 저작도구는 기능의 추가적인 확장을 통해 홈 내 가상화 장치들을 위한 응용 프로그램 제작에도 활용할 수 있다.

As the game industry is blooming, the generation of contents is far behind the consumption of contents. With this reason, it is necessary to afford the game contents considering level of game player's skill. In order to effectively solve this problem, Procedural Content Generation(PCG) using Artificial Intelligence(AI) is one of the plausible options. This paper proposes the procedural method to generate various monsters considering level of player's skill using genetic algorithm. One gene consists of the properties of a monster and one genome consists of genes for various monsters. A generated monster is evaluated by battle simulation with a player and then goes through selection and crossover steps. Using our proposed scheme, players adaptive monsters are generated procedurally based on genetic algorithm and the variety of monsters which are generated with different number of genome is compared.

실제공간체감을 극대화하기 위해 실제 물리적인 공간과 가상현실 공간을 융합하는 인터랙티브 아키텍쳐 기반 적응형 혼합현실 기술이 최근 연구되고 있다. 이러한 혼합현실 공간에서 동적인 사용자 위치에 따라 물리공간적 몰입감 증대를 위한 오디오 Sweet Spot 최적화 기술을 연구하였다. 이를 위해 주파수 대역 별 소리의 물리적 감쇠현상을 활용하여 주파수 별 오디오 신호 보상 전처리를 통해 동적인 사용자 위치에 원음과 동일한 음색의 오디오 Sweet Spot이 형성이 가능한지 실험한 결과 주파수 별 감쇠의 차이를 보정함으로써 원음 그대로의 음색이 재현될 수 있다는 것을 확인할 수 있었다.

The purpose of this study was to review articles and theses on adjustment of college freshmen from domestic researches conducted during the past 11 years, to identify overall research trends, and to suggest direction and strategies for college freshman's adjustment. The final 24 articles were selected from three databases, RISS, KISS, and NAL (National assembly library) using specific inclusion criteria. Twenty were correlation studies and four were experimental studies. In 2009, the first study on adjustment of college freshmen was published. Since then several more studies have been conducted to date. This means that people have recognized the importance of adjustment of college freshmen. Twenty three studies that are reviewed used Baker and Siryk's college adjustment tool. From reviewed correlation studies, mean score of college students' adjustment was 3.25. The related variables with adjustment of college freshmen revealed 20 items, especially self-esteem, self-efficacy, and stress showed important related concepts. The general characteristics related to adjustment of freshmen were outgoing character, living with family, aged students, satisfied with the area of study, and satisfied with school life. The findings of this study indicated that colleges when planning for the freshmen orientation program should focus on improving self-efficacy of students, stress management, mentor program, and freshmen adjustment program for each department of the school and college.

자본과 노력의 결실로 이뤄진 온라인데이터베이스의 정당한 가치를 보호하기 위해 우리나라는 저작권법, 컴퓨터프로그램보호법, 온라인 디지털콘텐츠산업발전법 등의 관련법을 제ㆍ개정해 이에 적극적으로 대처하고 있다. 구체적으로 데이터베이스의 보호를 강화하기 위해 2003년에 저작권법을 개정했다. 이것은 저작권법이 그만큼 빠르게 변화하는 추세에 적응하기 위한 노력이라고 평가할 수 있다. 아울러 컴퓨터프로그램보호법과 온라인디지털콘텐츠산업발전법을 제정해 시행하고 있다. 이에 이번호에는 온라인데이터베이스를 보호하는 저작권법, 컴퓨터프로그램보호법의 주요내용을 살펴보고 법적 문제를 다루고자 한다.

This study aims to examine the effects of adjustment factors to college life on the work values of public health major students. We sampled 530 undergraduate students majoring in public health administration and engineering from Kyunggi-do, and analyzed the data using t-test, correlation and regression methods obtained from SPSS Win 21.0 software. We found that (1) a student's intrinsic work value is positively related to their adjustment to college life factors but extrinsic work value is positively related to 'professor-student interaction', 'college life satisfaction' and 'expectation for the service college'; (2) 'social integration', 'professor-student interaction' and 'expectation for the service college' influenced to intrinsic work value; (3) 'career identity', 'family support', and 'college life satisfaction' influenced to extrinsic work value. Based on the results of this study, that the improvement of adjustment to college life factors influence on the work values were discussed.

The purpose of this study is to investigate the moderating effect of interpersonal relationship skills in adapting military life and stress in the army. For this purpose, 453 soldiers in Chungnam and Daejeon were surveyed. First, the main result of this study is the difference in interpersonal skills and group life adjustment in accordance with the rank and class of the soldiers. Second, too much stress can cause difficulty to adapt military life and interpersonal skills. Also high interpersonal skills can help to adjust well to military life. Third, according to the survey, it was confirmed that the openness in the sub-factors of military life and military life stress was effective. This study suggests that it is important to help control the stress of military life to improve the ability of the openness of interpersonal skills in order to increase the adaptability military life.

Pre-proposed AHHS(Adaptive Hierarchical Hexagon Search) is a kind of the fast hierarchical block matching algorithm based on the AHS(Adaptive Hexagon Search). It is characterized as keeping the merits of the AHS capable of fast estimating motion vectors and also adaptively reducing the local minima often occurred in the video sequences with higher spatio-temporal motion activity. The objective of this paper is to propose the method effectively extending the horizontal biased pattern and the vertical biased pattern of the AHHS to improve its predictive image quality. In the paper, based on computer simulation results for multiple video sequences with different motion characteristics, the performance of the proposed method was analysed and assessed in terms of the predictive image quality and the computational time. The simulation results indicated that the proposed method was both suitable for (quasi-) stationary and large motion searches. While the proposed method increased the computational load on the process extending the hexagon search patterns, it could improve the predictive image quality so as to cancel out the increase of the computational load.

This research was conducted to verify the moderating effect of gender, which impacts learning strategy, negative emotions, and influence that university life adjustment of undergraduates has on academic achievement. Therefore, this survey was conducted on learning strategy and negative emotion in February, targeting 654 freshmen of a university in Seoul on their academic and social adaptation and grades which has been measured and analyzed three months later at the end of the term. The moderating effect according to genders was analyzed through hierarchical regression analyses, and diagram was presented after conducting the simple gradient verification as a post analysis on interactive effect. As a result of analysis, although learning strategy and academic adaptation was appeared to be significantly affecting grades regardless of gender, the impact of negative emotions on academic achievement were significant only to females, and the impact of social adaptation on academic achievement was significant only to males, which enabled the researchers to confirm the regulation effects on different genders. The implications and proposal for a follow-up study about learning strategy, emotion, and adaptation based on the research resulted in the discussion of academic achievement in university.
