The purpose of this study is to examine the effect of the soldier's resiliency on the their adjustment in military. For the research, resiliency was consisted of interpersonal relation, vitality, emotion control, curiosity and optimistic. This study analyzed 150 military soldiers by survey. The results of this study are summarized as follows: soldier's resiliency and adjustment in military was showed high level. Soldier who had high resiliency adapted to the military life better than who had low resiliency. Interpersonal relation, curiosity and optimistic among resiliency showed positive influence on soldier's adjustment in military. This study finally discussed theoretical implications for future study and practical implications on the results.

In this paper, we propose a new dynamic syllabus composition system to solve the problems of a static syllabus which can appear in the field of computer education, where the relationship between pre-post study subjects is clear and teachers may grasp easily the degree of understanding of learners in real time. Our dynamic syllabus composition system is designed to be adjusted according to the physical change of the amount of education and the level of learners, which is based on the priority of educational objects. The result of instance performed on two groups of different entering behavior shows that the proposed method enhances the degree of transfer of education and helps us teach a class around the representative subject which has to be dealt with in the class, so that it is very effective for the achievement of educational objects prior to others.

In this paper, we present a 3D reconstruction method of color volume data for a computerized human atlas. Binary volume rendering which takes the advantages of object-order ray traversal and run-length encoding visualizes 3D organs at an interactive speed in a general PC without the help of specific hardwares. This rendering method improves the rendering speed by simplifying the determination of the pixel value of an intermediate depth image and applying newly developed normal vector calculation method. Moreover, we describe the 3D boundary encoding that reduces the involved data considerably without the penalty of image quality. The interactive speed of the binary rendering and the storage efficiency of 3D boundary encoding will accelerate the development of the PC-based human atlas.

The purpose of this study is to examine the effect of Gratifications Obtained (GO) on behavioral intention targeting Over-the-Top (OTT). The study chooses quality of content, variety of content, leisure activity, entertainment, the convenience of watching, and reasonable rate ratio as factors of GO. The number of subjects for the research is 330 people aged from their twenties to thirties in Daegu and Gyeongbok province. This study employs multi-regression analysis to analyze the impacts of GO on behavioral intention. The analysis shows that quality of content and variety of content influence behavioral intention at a significance level of 0.01, and entertainment and the convenience of watching influence at a significance level of 0.05.

Principal component analysis was used for ana1zing growth data to know the relationship between growth characteristics and yield as well as its components. The first principal component accounted for average time of the specific leaf area sampled, leaf area index, and dry weight, and the second component for the position of the changing point of growth characteristics. The component scores were more affected by the nitrogen level than variety. Yield were affected by fertility ratio and number of spikelets per hill which have close relation with the component score of leaf area index and dry weight per hill.

It is clear that students attending at technical high schools, which are commonly believed to have low mathematical learning standard, are able to improve their mathematical learning abilities through concrete operational activities. One thing that teachers should remember is that the subject in learning is the student not the teacher any more, so that teachers are able to become assistants by letting students study independently rather than passively.

G009는 단백다당체로서 분자량 0.5-200만 사이에 광범위하게 분포되어 있으며 구성당은 glucose를 주로하여 galactose, mannose 등으로 구성되었고, 아미노산은 glycine, leucine, alanine 이외 기타 아미노산으로 구성되어 있다. 담도결찰 쥐에서 G009투여군은 대조군에 비하여 간섬유화 유발물질로 추정되는 혈중 Procolagen type III peptide의 감소시켰고 간조직중 총 collagen의 양도 감소시켰다. 또한 조직학적 검사 결과로도 간섬유화의 억제가 뚜렷하였다. 각종 간손상 유발물질에 대하여도 G009투여군은 대조군에 대하여 정상군과 동일한 수준으로 GOT, GPT, triglyceride수치를 보였으며 간조직도 정상군에 가까운 결과를 보였다.

The frequency synthesizer thar has very short transient time is the key to construct the Fast Frequency Hopping(FFH) system. A Direct Digital Frequency Synthesizer(DDFS) whose transient time is in the nS range has been implemented and the performance of which has been examined through this paper. And by considering the hopping characteristic it is confirmed that the DDFS is suitable for the FFH system. Finally an improvement method which can greatly enhances the SNR with the state-of-the-art techniques and simplifies the system design is presented.

차세대 웹 문서의 새로운 표준으로 자리 잡아 가고 있는 XML은 전자 상거래나 병원 관리 등과 같이 다양한 응용 분야에 적용되고 있다. 이러한 응용 분야는 XML 문서의 각 구성 요소 수준의 세밀한 액세스 제어를 요구한다. 따라서, 현재 XML 문서의 미세 접근 제어 기법에 대한 연구가 활발히 이루어지고 있다. 현재 제안된 XML 문서를 위한 미세 접근 제어 기법은 대부분 묵시적 권한 기법을 사용하여 상위 구성요소에 한번의 권한 부여로 하위노드에 권한을 부여하는 효과를 가지는 장점을 가지나, 각 구성 요소간의 권한을 체크하는 시간 오버헤드를 가지는 단점이 있다. 본 논문에서는 권한을 체크하는 시간을 감소시키기 위하여 XML 문서의 미세 접근 제어를 위한 명시적 권한 기법을 제안하고, 이를 이용하여 노드의 권한에 대한 모든 정보를 저장하고 있는 접근 권한 트리 모델을 제시하였다. 본 논문에서 제안한 접근 권한 트리 모델을 사용하면, 권한 정보를 저장하는 공간 오버헤드가 있지만, 권한 체크 시간을 감소시켜 사용자에게 보다 빠른 뷰를 제공할 수 있다.
