This study analyzes the performance of school library rehabilitation project for the past four years. The project was launched in 2002 as a 5-year project from 2003 to 2007. Based on the analysis, the author suggests some considerations for the second phase of the project. First, librarians are the focal point to manage the library newly built and remodeled at a massive budget of 300 billion Korean won. Second, when developing curriculum employing school libraries, the curriculum should be differentiated by grade. class, textbook and even chapter. Third. the project should demonstrate the positive influence of school libraries on students' academic achievement so that the parents and community leaders voluntarily promote school libraries. Forth, the project should examine diverse users to successfully meet their demand. Fifth, the project should incorporate capacity building in librarian training course. It is also crucial that librarians themselves make visible effort to achieve an expert status before students and fellow teachers.

Gene expression in five tissues of the abalone (Haliotis discus hannai) was investigated using an expressed sequence tag (EST) analysis. Randomly selected clones were obtained from cDNA libraries constructed with gill (GI), digestive diverticula(DD), hepatopancreas (HP), foot/mucus (FM) and rectangular muscle (RM). Of 1,235 clonesanalyzed (288 clones for GI, DD, HP each,166 for FM, and 205 for RM), 741 (60.0%) clones in total turned out to share significant similarity with the sequences from NCBI GenBank (less than 10/sup -3/ of e-values), 423 sequences showed poor similarity (> 10/sup -3/), and 71 sequences didn't match with any sequences in GenBank. The percent unique sequence (singleton) was ranged from 56.1% (RM) to 74.7% (FM) among libraries. On the other hand, overall percent singleton was 55.3% when all the ESTs from five libraries were assembled into contigs. Analysis of the organisms represented by the best hit for each EST (e-values < 10/sup -3/) showed that 23.8% matched with mammalian entries, 24.0% with mollusks, 14.4% with insects, 11.6% with fish and 26.2% with others. The expressed patterns differed among the tissues when judged by the categorization of the sequences from each library into 10 broad functional classes. In all the libraries, the class I (no hit o. poor similarity) was the largest category with an average of 40.1%. This largest class was followed by class V (general metabolisms) in DD (21.9%), GI (14.6%) and HP (16.7%), while the 'cell structure and motility'(class VI) was the second largest class in remaining two libraries (31.2% for RM and 9.6% for FM). The class IX (cell division and proliferation) was the smallest class in all the libraries (less than 3%). This report provides the first tissue-specific lists of expressed abalone genes, which could be a fundamental basis for genomics program of abalone species.

In the present study, a post-processing program is developed for 3D data visualization and analysis. Because the graphical user interface(GUI) of the program is based on Qt-library while all the graphic rendering is performed with OpenGL library, the program runs on not only MS Windows but also UNU and Linux systems without modifying source code. The structure of the program is designed according to the object-oriented programming(OOP) concept so that it has extensibility, reusability, and easiness compared to those by procedural programming. The program is organized as modules by classes, and these classes are made to function through inheritance and cooperation which is an important and valuable concept of object-oriented programming. The major functions realized so far which include mesh plot, contour plot, vector plot, streamline plot, and boundary plot are demonstrated and the relevant algorithms are described.

The major cuticular components have been shown to be synthesized in the epidermis. Therefore, cloning of epidermis-specific genes could yield information to be used to isolate and characterize the enzymes involved in the cuticle biosynthesis. A subtractive cDNA library was prepared from Senecio odorus in which epidermis-specific cDNAs were enriched. Differential screening of the library using epidermal and non-epidermal probes revealed two cDNAs. One of them designated epi425 was identified, based on the sequence homology, as a member of a new class in the LTP gene family and the other clone designated epi23 as a gene encoding an aldehyde decarbonylase. Northern blot analyses showed that epi425 and epi23 cDNAs hybridized with a transcript of about 600 and 2, 100 nucleotides, respectively, from the epidermis but not from the non-epidermal tissues. Further characterization of these clones will provide more information on the mechanism of the cuticle biosynthesis.

This study is to suggest a classification system to classify the agricultural information resources on the internet. In the first part, I analyzes KDC's class 520(agriculture science). The second part compares the agricultural classes of Yahoo! Korea with those of Empas search engine. The third part compares the classes of AFFIS with Agri_Directory. Based on the comparative analysis, it proposes a classificatory system for the agricultural information resources on the internet.

The purpose of this study is to confirm what the stress factors are in performing their jobs among librarians in Public libraries. The study further investigates to figure out the difference of the degree in cognition of job stress according to demographic characteristics of individuals and the impacts of the stress factors on job satisfaction. A survey was conducted for the study sending questionaires to 113 librarians working in 14 Public libraries in Pusan. The results of the study are followings: 1) Females experience higher job stress than males. 2) The younger the age, the higher the job stress. Also, the shorter the year at work, the higher the job stress. 3) The lower the license class, the higher the job stress. Also, singles than married have higher job stress. 4) In the impacts of stress factors on job satisfaction, role conflict is the most powerful factor, and then role overload, career development, role underload, role ambiguity and interpersonal relation, each in order.

This research has been done to evaluate a curricular model for the information literacy course and verify its effectiveness in a regular class. The pretest and the post-test which comprised the same 47 questions were executed to 135 students in an information literacy-related course. On the basis of the results, some general conclusions and suggestions for improving the quality of information literacy course were made.

병렬 프로세서 시스템이 제고하는 하드웨어적인 장점을 이용하기 위해서는 병렬 프로그래밍을 통한 애플리케이션의 병렬화가 필요하다. 기존의 순차적 코드의 경우에 자동 병렬화 컴파일러 기법을 통하여 병렬 프로세서시스템이 제공하는 성능을 극대화하고 있다. 그러나 자동병렬화는 과학 기술 계산용 코드와 같은 정형성을 지닌 코드에서는 유용하지만 비즈니스 응용에서 사용되는 동적인 자료구조를 사용하는 코드에서는 포인터에 의한 별명과 이에 따른 의존성 분석에 어려움으로 인해 많이 응용되고 있지는 못하다. 본 논문은 병렬 프로세서 시스템이 제공하는 기능을 이용하기 위한 한 방법으로 비즈니스 응용에서 많이 사용되는 동적인 자료 구조 중 linked list 클래스 라이브러리의 설계와 구현에 대하여 기술한다.

Framework has constructive and extendable code. It is consist of the variable design collections. In the aspect of the classes's collection, it is similar to the class library. but it is different to provide the architecture which is possible to develop the application rather than the collection of the simple classes. In framework it is very important factor to develop and control the component library. In this paper, we design the usable component model through defining the meta-relation between components and proposed the sample case using this model.

A geometric kernel is the library of core mathematical functions that defines and stores 3D shapes in response to users'commands. We developed a light geometric kernel suitable to develop CAD/CAM application systems. The kernel contains geometric objects, such as points, curves and surfaces and a minimal set of functions for each type but does not contain lots of modeling and handling functions that are useful to create and maintain complex shapes from an idea sketch. The kernel was developed on MS-Windows NT using C++ with STL(Standard Template Library) but it is compatible with UNIX environments. This paper describes the structure of the kernel including several components: base, math, point sequence curve, geometry, translators. The base kernel gives portability to applications and the math kernel contains basic arithmetic and their classes, such as vector and matrix. The geometry kernel contains points, parametric curves, and parametric surfaces. A neutral fie format and programming and document styles are also presented in this paper.
