Our study aims to provide a guideline of deer-proof fence heights to prevent roadkill of water deer (Hydropotes inermis), the most frequently killed by a vehicle collision, in South Korea. With 27 water deer in deer ecology center of the National Institute of Ecology, we measured the ability of water deer to jump gradually higher fences from 0.5cm by 10cm until the deterrence rate reached 100%. Ourresultrevealed that the deterrence rate became 96.7% at the fence height of 1.5m and the rate reached 100% at the 1.8m. We believe that our result provides the fundamental information to prepare a standard of deer-proof fence height. This evidence-based standard will contribute to improving the guideline for wildlife crossing construction and management, established by Ministry of Environment Korea.

The objective of this study is to identify the difference in attitude toward medical care between patients who visited a university hospital or an oriental medical hospital of oriental medical college, and physicians who engaged in the same hospitals. The subjects of this study were 397 cases who agreed to respond the prepared questionnaire, including 288 patients(146 university hospital utilizers and 142 utilzers for an oriental medical hospital) and 109 physicians(76 physicians and 33 oriental medical doctors). The attitude toward medical care was measured by the structured questionnaire developed for this study, which had high validity and reliability according to factor analysis, item discriminant validity, and Cronbach's $\alpha$ coefficients. On the criteria of mean value of care and cure score, the attitude toward medical care was classified into 4 groups encompassing a group with dependent attitude on medical care, a group with skeptical attitude toward it, a group with cure-oriented attitude, and a group with care-preferred attitude. The results of chi-square test, discriminant analysis, and logistic regression analysis were as follows; patients who visited a univisity hospital, patients who visited an oriental hospital, physicians, and oriental medical doctors included in the group with dependent attitude, the group with cure-oriented attitude, the group with skeptical attitude, and the group with care-preferred attitude, retrospectively. Among the subdomains of care and cure domains, which classified in reference to the result of factor analysis on pilot study, those that patients ranked more importantly than physicians were 'the importance of medical equipment for diagnosis and treatment', 'authority of physician, 'aggressiveness of treatment', 'information giving', 'personal interest' in the case of western medicine. In the case of oriental medicine, those were 'the importance of equipment for diagnosis and treatment', 'aggressiveness of treatment', 'amenities and accessibility', 'coordination of medical staff'. Both physicans and patients put the subdomain, 'physicians' medical knowledge and skillfulness' on the highest rank. The differences in ranking the important attributes of medical care between patients and physicians were apparent in the area of an 'importance of medical equipment for diagnosis and treatment' and so on. It meant that patient had over-expectation on medical care and suggested that the policy on demanad side such as the developement and dissemination of an evidence-based recommendation protocol for health care consumers might be important in Korea. In addition, regarding the attitude of physicians, during the medical education and training it may be neccessary to emphasize the aspect of 'care' of medical care rather than 'cure'. In planning on heath care delivery system, it should be considered that there is a difference in the attitude toward medical care between western medicine and oriental medicine as well as between health care providers and consumers. We expect that more valid measurement tool be developed in this area, which may be major limitation of this study and that this kind of research be expanded into the non-academic settings.

WSN has been utilized in various directions from basic infrastructure of environment composition to business models including corporate inventory, production and distribution management. However, as energy organizations' private information, which should be protected safely, has been integrated with ICT such as WSN to be informatization, it is placed at potential risk of leaking out with ease. Accordingly, it is time to need secure sensor node deployment strategies for stable enterprise business. Establishment of fragmentary security enhancement strategies without considering energy organizations' security status has a great effect on energy organizations' business sustainability in the event of a security accident. However, most of the existing security level evaluation models for diagnosing energy organizations' security use technology-centered measurement methods, and there are very insufficient studies on managerial and environmental factors. Therefore, this study would like to diagnose energy organizations' security and to look into how to accordingly establish strategies for planning secure sensor node deployment strategies.

Fresh Kills is the largest landfill in the world located in the west side of Staten Island, New York. The landfill served as a storage area for New York City's trash for more than 50 years. After years of civilian and political pressure, state and local legislation decided its closure of landfill operation in Fresh Kills in March 2001. Soon after, Department of City Planning announced a Fresh Kills international design com-petition: 'Landfill to Landscape'. The winning entry was promised to be outline for the redevelopment of the 2,200 acre site which the size of three times Central Park. Forty-eight teams representing more than 200 offices from around world submitted proposals, from which six finalists that mostly led by landscape architects were selected. In December 2001, a jury of architects, landscape architects and city officials unanimously selected Field Operations as the winner. The plan, named Lifescape, visualizes the gradual 20-year transformation of the whole Staten Island into a 'natural lifestyle island' recognizing that Staten Island is home to coastal wetlands that shelter one of the most diverse ecosystems in the New York metropolitan area. It suggested that an ecologically reconstituted Fresh Kills could become the center of integrated parks and greenways system on the island otherwise fragmented. The project will be one of the largest and most ambitious undertakings in the metropolis in years developing a complex web of habitats and parklands on top of mountain of trash. This study tries to achieve two goals: One is to provide general explanations on the project, Lifescape, breaking down to its background, geographical context, design concepts and phased development plan. Another is to introduce the unique and innovative design approaches by Field Operations that are different from a conventional landscape architectural attitude. Since this project was well published through many magazines and newspapers, main focus will be upon aspects that differentiate this project from usual landscape projects. Conceptually Lifescape brought provocative notions on nature/culture relationship and the role of urban park as an active agency rather than just a green rest area. Also this project introduced pioneering graphics like plan collage, diagrammatic plan, phasing diagram and photo montage as vehicles conveying information, imagination and provocation. Witnessing the influence of the project gradually in the field of academic and practice in the States, this study is intended to become a constructive reference to similar landscape projects dealing with large and complex urban context in conjunction with restructure of contemporary city.

Reduced crew performance is frequently cited as a major causal factor in maritime accident causation. Although considerable research has been conducted on the hours of work undertaken by seafarers through interviews and the analysis of records, experimental studies to observe the effects of factors such as high workload, shift patterns, stress, sleep deprivation and disturbance on the cognitive performance of mariners have been limited. Other safety-critical transport industries, such as aviation and rail, have developed fatigue management tools to help manage the work patterns of their operators. Such a tool for mariners would assist shipboard crew, marine pilots and shore management in planning and improving work schedules. The overall aim of this paper is to determine a fatigue factor, which can be applied to human performance data, as part of a software program that calculates total cognitive performance. This program enables us to establish the levels of cognitive performance of a group of marine pilots to test a decision-making task based on radar information. This paper addresses one of the factors that may contribute to the determination of various fatigue factors: the effect of different work patterns on the cognitive performance of a marine pilot.

The whole design process drawing outputs from design planning is based on designers' intuitive ideas and differences in technical ability. However, every design professional agrees to the fact that such design process is filled with individuals' implicit acts or inherent intuition rather than following directions in a certain defined frame. If the design process based on such intuition and experience can start from the rational and scientific process, it would be possible to move more systematic design process to the next step. This study aims to examine what system of thinking are used by designers to conduct the design information process, by using the protocol analysis which is the representative qualitative study method of cognitive science, on designers' cognitive behaviors like the contents of the design sketch process which is the initial step of the kitchenware development process, in order to understand professionals' and non-professionals' design application direction. Thus, the scope of this paper would be limited to "the initial protocol analysis on kitchenware" and "encoding of the analysis on thinking" in the qualitative study that can be the most basic to understand the design cognitive science. As a procedure to solve this study question, it aimed to seek for the product development flow and the educational effect by considering the preceding researches and also re-interpreting cognitive thinking in systematic methods.

Allocated water storage of dam at the planning and design stage does not seem to be maintained well at the operation stage because of unexpected critical reasons. A dam is likely to be subject to negative effects caused by changes of dam operation conditions and it is hardly avoidable. Therefore, it must be timely improved to recover its original functions and looked for better alternatives to keep its original roles. Specifically the improper management of river condition degrades flood control capability in a dam and river eco-system. The dam downstream river improvement work is needed for normalizing dam functions and its valuations. This study focuses on estimating water use benefits from recovering its own effective storage buffer restricted for flood control. As the results, the water supply and the hydropower benefits in Imha, Daechung and Youngdam Dam are recovered totally by 19.9 million $m^3$/year and 20.8 GWh/year respectively. Also those results are used for the basic information of the economic analysis in the dam downstream river improvement work.

The conventional four-step travel demand model is still widely used as the state-of-practice in most transportation planning agencies even though it does not provide reliable estimates of travel demand. In order to improve the accuracy of travel demand estimation, implementing an alternative approach would be critical as much as acquiring reliable socioeconomic and travel data. Recently, the role of travel demand model is diverse to satisfy the needs of microscopic analysis regarding various policies of travel demand management and traffic operations. In this context, the activity-based approach for travel demand estimation is introduced and a case study of developing a spatial-temporal activity presence-based approach that estimates travel demand through forecasting number of people present at certain place and time is accomplished. Results show that the spatial-temporal activity presence-based approach provides reliable estimates of both number of people present and trips actually people made. It is expected that the proposed approach will provide better estimates and be used in not only long-term transport plans but short-term transport impact studies with respect to various transport policies. Finally, in order to introduce the spatial-temporal activity presence-based approach, the data such as activity-based travel diary and land use based on geographic information system are essential.

This report is the result of interim evaluation of a health promotion project which was operated by a public health center of K Gu in the year of 2000. It evaluated the aspects of the aim of a project, a target group. and adequacy and appropriateness of a approaching strategy by considering data of public health center's self-evaluation, and guidelines of a group assigned to evaluate the project. The way of evaluation was dividing the project into a colligated evaluation and a evaluation by projects in the aspects of the structure, the procedure. and the result of a result. Through this. a device to improve the health improvement project was derived. The target data for evaluation was the second data and data of self-evaluation, reported data, membership register data of a health management. and interview materials with the people in charge by projects that are all collected as a project management documents. The result of evaluation is stated below. 1. Main purpose of a health promotion project is building a environment of healthy life practicing and providing information through various ways to increase the rate of practicing healthy life. Through overall project. the ultimate purpose and definite purpose were same, however, it was not quite satisfied to offer planning of a time, and a target amount in detailed strategy. As the purpose was to build environment of healthy life practicing. most of the projects had the whole community citizen as a target group. That made difficult to operate detailed projects. so the result was hard to estimate as much as the effort put into it. Also, there were too many kinds of projects and target groups to be equal to by the human source of a health promotion project team. so we were just bent on operating a project. and could not prepare for the evaluation. As the most of former evaluation of public health service was just counting number of the objects, the new way of evaluating a project wasn't familiar to us. so the evaluation of a detailed project cannot be done well. Techniques and advices needed for all of these things weren't offered appropriately. For the forward direction of unfolding project. it is desirable to operate project by selecting focused target and considering a strategy of evaluation as a strategy of reasonable spread. The evaluation of the project became difficult as participation of citizen for it was poor. So, approach strategy that can lead the motivation of community citizen should be derived. 2. For the continuation of a health promotion project, technical assistance system. description of a field in charge, and arrangement of the amount of task should be developed as a central level. Furthermore, as the health promotion project focus on behavioral modification program whose purpose is to lessen dangerous factors. the public health service model which is incorporated with former project should be developed and spread out in the field for the object-centered project plan.
