This study came up a library thought and the theory of cataloging through analyzing the life and writings of Seymour Lubetzky who founded the principals of cataloging in the twentieth century. This study investigated the historical social, ideological, and cultural context, using a literature survey and the methodology of historical research. Moreover, this study aimed a comprehensive research based on the results of domestic and foreign fragmentary studies, and analyzed the effects of Lubetzky's thought of cataloging. Thus, this study found Lubetzky's library and cataloging thought. The theory of cataloging that analyzes the above findings is the design of cataloging rules and a bibliographical relationship establishment. First of all, the principles of descriptive cataloging should contain the necessity, simplicity, unity, consistency, finality, and the characteristics of interrelations, and clarify the purpose of cataloging. The bibliographical relationship is built on dividing a work as an intellectual product into a book as a physical substance. Moreover, a basic entry is entered on the basis of author names for planning the concentration of works, and a corporate name and an anonym are contained in the author names for extending the concept of author.

Yamada's mountain ordering is to be said as an upward system, because the area and volume of the mountains become the larger as more than two lower order mountains constitute the higher order mountain. However, his mountain ordering shows some limitations to totally understand the mountain systems and to systematically manage the various kinds of mountainous informations. Because the independent third, fourth and so on, as well as the second lower order mountains are included in the higher order mountain. In order to solve the problem above, the downward system is suggested as the alternative of his upward system. The downward system means that the higher order mountain is classified into the second lower order mountains, and the second lower order mountain is classified into the third lower order mountains and finally the 2nd order mountain classified into the 1st order mountains. The method to classify a certain mountain systematically into all mountainous elements and the new nomenclature to be used for the classified elements are developed, using the downward system above. And the structure of database could be also suggested for the integrated and systematic management of mountain informations.

One of the important roles used to ensure victory in a war is to maximize the overall military forces and to make sure that the capability of the military forces can be sustained as much as possible. Although several researchers have proposed various possible methodologies for logistics support, no research trials have been undertaken to investigate logistics support that considers all relevant elements of such. Unlike previous in trials that consider and analyze the system fault ratio as the main methodology, we propose an approach that simultaneously decides and recommends logistic priority by reflecting and combining item costs, transportation, fault-ratio, and system complexity. Also, we designed an algorithm that can recommend optimized logistics support priority using stationary distribution.

This research was examined to evaluate whether the websites of 6 policy research institutes provide web resources which were collected and provided as information resources, and that they were sure that the web resources had value as policy information by content analysis method. Web resources provided as policy information in policy research institutes were classified into and evaluated by 4 categories. Evaluation had been conducted on 10 items in the 4 categories of content, design, accessibility and meta data. From the result, the information content have been found to be reliable and up-to-date although more thorough description is required. Navigation and the search function in the design category were found to be excellent, but dead links were present in all of the institutions. The accessibility was proven to be great as it was able to access information with only three clicks. However, it has been found that a comprehensive review of the meta data is required in order to improve the accuracy of search functions. In conclusion, improvements to the dead link problems, quality control of the meta data, systematic and professional management plan of policy research information, and the establishment of a comprehensive policy research information portal system have been proposed.

진천지역의 지하수 유동체계를 분석하기 위해 진천지역 내 530개 공의 지하수위를 1년간 관측하였다. 이중 360개 공에서는 분기별로 한번씩 총 4회, 130개 공에서는 월1회씩 총 12회 지하수위를 관측하였으며, 40개 공에 대해서는 1시간 간격으로 자동관측을 실시하였다. 관측결과를 수집하여 지하수위의 변동특성, 지하수위 분포, 지하수 심도분포 등을 실시하였으며, 이와 같은 지하수위 분석 결과를 바탕으로 지하수 유동체계를 분석하였다. 조사지역의 평수기 지하수위 분포에 대해 수리학적인 접근법(hydraulic approach) 및 동수역학적 접근법(hydrodynamic approach)에 근거하여 수리수두(hydraulic head) 및 전수두(total head)를 분석하여 2차원 및 3차원 수리경사도를 작성하였다. 이러한 지하수위 분포에 따른 분석 성과와 지형 및 수문지질을 고려하여 함양 및 배출지역을 분류하였으며, 이와 함께 기분석된 지하수위 등고선에 따른 유선망도를 작성하였다. 지하수는 지하수위의 표고 및 압력에 따른 위치 에너지 차에 의하여 대수층 매질을 통하여 유동하며 수두가 높은 곳에서 낮은 곳으로 일정한 수리경사를 갖고 지하수 등수위선에 연직 방향으로 형성된 유선을 따라 이동한다. 따라서 지하수의 유동방향은 지하수 수리경사 분석이 이루어진 8개 방향의 지하수위 경사 중 최대경사를 갖는 방향으로 지하수 유동이 발생하므로, 이를 지하수위 유동방향으로 결정하였다. 이와 같이 분류된 지하수 함양 중간 및 배출 지역과 지하수의 함양과 배출의 양적인 측면에 서 유동체계의 규모를 고려하여 조사 지역을 8단계로 구분하였다. 또한 조사지역의 지하수 유동체계를 종합적으로 규명하기 위하여 기 분석한 조사지역의 지하수위 등고선, 지하수위 등심도선, 지하수 수리경사, 지하수 유동방향 및 지하수 함양-배출체계와 지형기복, 그리고 주요 하천 등의 제반 요소를 중첩 분석하여 종합적으로 규명하고, 그 결과를 지하수 유동체계도로 작성하였다. 지하수 유동체계 분석결과는 수문지질 평가와 오염취약성 평가 및 지하수 관리 방안 수립에 활용될 수 있을 것으로 기대된다.

Panax ginseng has often been suggested as a geriatric restorative. This study is a double blind crossover trial to test whether ginseng can improve function in subjects with the depression and reduced abilities associated with senescence. 49 screened subjects were given 1500 mg Korean Red ginseng and identical placebo each for ten days, with a washout period in between the dosages. Standard tests of mental function, neuromuscular reflexes, responsiveness, mood and well being were used. The subjects were somewhat better at the co-ordination and speed test ('number copying') but tests of concentration and memory ('Concentration', 'Paired Association', 'Digit Span' and 'Object Learning') gave equivocal results. There were small improvements in mood and well being ('Life Satisfaction' and 'General Health Questionnaire') while the subjects indicated increased energy, alertness and less sleep, but also less happiness on the daily analogue scales. The major result was a highly significant improvement in reactivity, speed and co-oridnation at the tapping test, and the visual, auditory and disjunctive reaction timer. These are the most objective and accurate tests used in this trial. It is therefore concluded that ginseng can increase function in senile individuals. This effect is most easily visualisable in objective psychophysical tests, rather than the more subjective memory and concentration tests.

The purpose of this study is to investigate the research trends and the present conditions of real digital texts on "Visual Transformation." For the purpose of this study adopted two different methods: meta analysis and case study. The research trends on visual transformation of digital text were investigated through analyzing the total of 167 literature by means of synthetic meta analysis. Relevant literature was categorized into three types of research: functional, dynamic, and interactional transformation. The type of literature and research methods in each literature were analyzed. The present conditions of real digital texts on visual transformation were investigated by means of case study. The well designed 12 e-learning contents selected and analyzed in terms of the analysis framework which was drawn by the research trends. The results suggested problems as follows in designing e-learning contents. Firstly, there were some cases that did not follow the basic design principles related to typography. Secondly, the content was just provided in each learning steps without consideration of design to enhance text comprehension in many cases. Thirdly, web technology adequately was not applied to design e-learning contents.

Last February, $\ulcorner$The Act on Ubiquitous City Construction and etc.$\lrcorner$ was approved by the National Assembly. The law stipulates the regulations on the planning, construction and management of the Ubiquitous City. As its national-level law system is about to take its effects, future new city developments are expected to have its legal basis to be built to meet ubiquitous city requirements. Also, it is anticipated that such needs would require much more planning techniques and strategies. In reaction to those upcoming needs, this study is to search for new planning approaches to realize the u-City in reality. It is also to supply with the framework to execute the u-City projects in more structuralize and systemize manner. Therefore, with the purpose of the establishment of comprehensive planning system, the theoretical bases were sought in relation to planning u-City, pre-existing u-City development cases and regarding regulations were analyzed, and then basic concepts, features, and constituent factors were set up.
