Dewey Decimal Classification (DDC) was first published in 1876. Since its first edition it has been revised, on an average, 6 years, and now it has become the widely used library classification system of which the scheme was translated in various languages. The purpose of this study is to find out the chief causes for the development of the DDC. The results of the study can be summarized as follows: 1. It allows materials to be shelved in a relative location as the collection expands. before the DDC was introduced, libraries used a fixed location for materials in which each item was assigned to a certain location set aside for a subject. 2. It is a practical system. The fact that it has survived many storms in the past hundred years and is still the most widely used classification scheme in the world today attests to its practical value. 3. The pure notation of arabic numerals is universally recognizable. People from any cultural or language background can adapt to the system easily. 4. The use of the decimal system enable infinite expansion and sub-division. And it has adaptability for use in libraries of various size and kinds because of its hierarchically expressive notation which permits varying degrees of inclusiveness and exclusiveness within its decimal structure. 5. The notation is simple and easily understood. The self-evident numerical sequence facilitates filing and shelving. And the mnemonic nature of the notation helps the readers to memorize and recognize the class numbers. 6. The relative index brings together different aspects of the same subject scattered in different disciplines. 7. We can avail of DDC numbers for specific titles easily because of its use by many central bibliographic services. 8. It is being continuously revised by a permanent office established in the library of congress in 1933. This office has been responsible for editing all editions of the DDC since the 16th (1958). And the periodic revision at regular intervals ensures the currentness of the scheme. 9. It has adaptability both for conventional (manual) shelf or classed catalogue analysis and also, through its meaningful nation, for retrieval through mechanization and computerized systems.

Background: Recently, the number of patients visiting pain clinics has been increasing with the augmented concerns of those patients about the management of their pain. We conducted this study in order to elucidate the characteristics of patients visiting pain clinics and to determine a method to further raise their awareness about pain treatment. Methods: We reviewed 1,424 new patients who visited our pain clinic from March 2003 to December 2004. We analyzed these patients according to their age and sex, treatment method before visiting the pain clinic, coexisting disease, chief complaint and pain location, resident district, route of visiting pain clinic, and degree of impairment due to pain by use of questionnaire. Results: In age distribution, the largest proportion (23.5%) was in their 50's. Most patients (64.0%) had received treatment in an oriental medicine clinic before visiting the pain clinic. The most common coexisting disease was hypertension (20.3%) and low back pain was the most common chief complaint (68.3%). Most of the patients lived in Gyeonggido (87%) and most visited our pain clinic on the recommendation of other patients who had visited our pain clinic before. Conclusions: We need to guide pain patients to undergo proper treatment much earlier using patient education or a referral system. Moreover, we should be more careful in patients with diabetes mellitus, and should have greater concern in the treatment of low back pain.

장애인복지관은 장애패러다임의 변화와 더불어 사회서비스 체계의 민영화, 사회복지시설 평가 강화로 경쟁체제로의 전환을 요구받고 있으며 국고보조금의 축소로 재원마련도 고심해야 하는 환경에 놓여있다. 2000년 이후부터 환경변화가 급속화되면서 장애인복지관의 최고관리자들은 조직의 존립과 발전을 동시에 생각해야 하는 리더십의 과제에 직면해 있다. 본 연구에서는 이러한 환경변화 속에서 장애인복지관의 발전을 도모할 수 있는 효과적인 리더십을 분석하기위하여 Weick(1995)의 센스메이킹(sensemaking) 이론적 틀에 근거한 질적연구를 실시하였다. 서울, 경기 지역 소재 장애인복지관 6곳의 관장, 팀장, 실무자와 한국장애인복지관협회 직원 1명을 포함한 20명이 연구에 참여하였다. 2012년 3월 말부터 5주에 걸쳐 반구조화면접을 실시한 후 녹취록을 Atlasti 질적분석 프로그램을 이용하여 주제별 분석을 하였다. 연구결과 구성원의 환경인식, 조직의 방향성 정립, 직위 간 의사소통의 세가지 주제들로 분석할 수 있었다. 결론적으로 6개 장애인복지관은 같은 환경변화 하에 놓여 있었지만 최고관리자의 센스메이킹 여하에 따라 중간관리자는 물론 일선실무자의 업무 인식과 실행이 영향을 받고 있음을 알 수 있었다. 최고관리자가 자신의 경험에 대한 성찰과 더불어 구성원과의 상호작용이 일상적으로 이루어지는 센스메이킹을 할 때 조직 구성원들을 같은 방향으로 이끄는 리더십이 발현되는 것으로 해석되었다.

The bogie of monorail vehicles applies rubber wheel system not steel wheel system. In addition, The structure of the bogie is very complicated because vehicle operates on the elevated road and vehicle drives with wrapping the guide way. When the monorail vehicle applies air brake system, lower device of vehicle may be complex and some devices may be limited. On the other hand, hydraulic brake equipment is compact and not weighing. Braking force is also outstanding compared with air brake so the hydraulic brake equipment is suitable for monorail vehicle. Also urban transit system such as monorail, applies mixed system both friction brake and electric brake in order to save electric energy. But application case of hydraulic brake in the country is very rare because hydraulic brake have difficulty in satisfaction of control requirement and maintenance. Therefore, this study suggests ways to design hydraulic brake system with blending brake for monorail vehicle and applies the ways to future monorail.

For the system benefit optimization by considering risk or reliability from a multiple reservoir system using the Monte Carlo Technique, Many stochastically generated inflow series have to be used for the system analysis. In this study, the stochastically generated inflow series for the multiple reservoir system operation are preprocessed according to the considering system objectives and operating time periods. Through this procedure, several representative inflow series which have discrate probability levels and operation horizons are selected among the thousands of generated inflows. Then a deterministic optimization technique is applied to the hydropower energy estimation from the Han River Reservoir System which considers five reservoirs in this study. It took much less computational requirements than using the original Morite Carlo Technique, even though estimated result was almost similar.
