US DoD operated JCIDS(Joint Capability Integration and Development System) for top down requirement generation. Although the JCIDS can be a good practice for the countries which are trying to shift from bottom up to top down requirement generation, it contains many processes related with review and approval. In this study we structured a joint capability integration and development process from the JCIDS eliminating the organization dependent review or approval process so that it can be applied to any organization with some modification. Furthermore we implemented the process in the computer aided systems engineering tool, Cradle, for convenient use of the process. The result of this study can provide a basic process for top down capability development, and an efficient why of doing each element of the process using CASE tool.

Although 19 years have passed since the enforcement of the Framework Act on Health and Medical Services, the Plans for Development of Health and Medical Services has not been established. This Plan is a 5-year basic long-term plan that covers the whole of health and medical services. This Plan should point to the direction of 30 long-term plans of healthcare, and this Plan should serve as a combination and coordination of 30 long-term plans and 22 related laws. The United States, the United Kingdom, and Japan have established long-term healthcare plans (4-, 10-, and 20-year plans, respectively). The long-term health plan of the United States has been approached bottom-up, those of the United Kingdom and Japan have been approached top-down. The rapid environmental changes that Korea is and will be experiencing emphasize urgently the need for establishing the Plan for Development of Health and Medical Services.

Biological and chemical characteristics and trophodynamics in the frontal zone were investigated in the southern waters of Korea, Temperature, nutrients (dissolved inorganic nitrogen, $PO_4^{3-}-P$, and $SiO_2^{-}-Si$) chlorophyll a and zooplankton were collected and analyzed along the two transects, the frontal zone and the non-frontal zone, in April, 1994. Nutrients were higher in the non-frontal zone than in the frontal zone. But chlorophyll a concentration was high in the frontal zone, particularly at the 20 m depth of the main frontal station (St. TII-2), where was located at the junction between the stratified layer and the non-stratified layer with the lowest nutrients. Zooplankton was more abundant in the frontal zone than in the non-frontal zone, particularly at the innermost station of the frontal zone. Copepods showed high composition rate more than $90\%$ at all stations except the main frontal station (St. TII-2). At the main frontal station (St. TII-2), euphausiids and siphonophores were dominated. Chlorophyll a revealed a significant relationships with $SiO_2^{-}-Si$ in both transects and copepods in the non-frontal zone. Copepods also showed very close relationship with siphonophores in the frontal zone. This suggests that the abundance of copepods could be controlled as bottom-up in the non-frontal zone and as top-down in the frontal zone.

Cost information in the Korean construction industry is mainly controlled by the government agencies. However, there have been wild-spread speculations among participants on the adequacy of these unit prices and difference with the actual market condition. Korean public-led unit prices are developed using mainly a top-down approach by a few designated public institutions. Due to the rapid fluctuations in market prices and high-volume of information, it is impossible for a few public institutions to properly consider market conditions. However, there are almost none private cost reference while many are available in other countries to supplement the public cost references. Needs for private cost references have recognized, and this study can be seen as a pilot study to support them. This study attempts to identify the problem areas of Korean cost references and to provide guidance by benchmarking other countries. This study has confirmed the need of developing market-driven cost references by employing a bottom-up approach in which a large number of various construction participants are fostered to provide their own cost information and share with others. It is envisioned that this study provides foundations for further study on the development on-line construction market platform based on abundant and appropriate cost information.

Introduction of wave model, considered the effect of shoaling, refraction, diffraction, partial reflection, bottom friction, breaking at the coastal waters of complex bathymetry, is a very important factor for most coastal engineering design and disaster prevention problems. As waves move from deeper waters to shallow coastal waters, the fundamental wave parameters will change and the wave energy is redistributed along wave crests due to the depth variation, the presence of islands, coastal protection structures, irregularities of the enclosing shore boundaries, and other geological features. Moreover, waves undergo severe change inside the surf zone where wave breaking occurs and in the regions where reflected waves from coastline and structural boundaries interact with the incident waves. Therefore, the application of mild-slope equation model in this field would help for understanding of wave transformation mechanism where many other models could not deal with up to now. The purpose of this study is to form a extended mild-slope equation wave model and make comparison and analysis on variation of harbor responses in the vicinities of Ulsan Harbor and Ulsan New Port, etc. due to construction of New Port in Ulsan Bay. We also considered the increase of water depth at the entrance channel by dredging work up to 15 meters depth in order to see the dredging effect. Among several model analyses, the nonlinear and breaking wave conditions are showed the most applicable results. This type of trial might be a milestone for port development in macro scale, where the induced impact analysis in the existing port due to the development could be easily neglected.

The purposes of this exploratory study were to interrelate the scholastic discipline of the ‘development communication’ into ‘community development’ and ‘adult education’ in terms of interests, views and theoretical backgrounds of these fields of social sciences; and to draw some implications for developing scholastic interactions among these fields to pursue common social changes of human society. Development communications provide opportunities to set goals, to decide contents, and to utilize communication media in developmental efforts. Contemporary trends of development communication, community development and adult education are concerned with indigenous, two-way, bottom-up and people-centered communication from exogenous, one-way, top-down and institution-centered communication of the past. Multidisciplinary approaches to communication concepts and methodology may increase the potentials of community development and adult education in terms of efficiency and effectiveness. Some of the development communication approaches such as traditional and folk media approach. new media or ICT(information & communication technology) approach, participatory communication for development approach, communication support development approach and mass media approach may be applicable for community development and adult education. Better understanding on development communication approaches will be needed for the adult educators as well as community development practitioners.

We have been aware fer some time. that it is becoming harder to develop ASIC only, using the vendor wire model for the current top-down/bottom-up process. Because VDSM has a much bigger wired delay than cell delay, it is also difficult to reduce development time, as well as time-to-market, while developing several million gate ASIC's. The same is true for high frequency ASIC's with VDSM (which have larger wire delay versus cell delay). Therefore, a solution called “RTS-GDS”, using physical constraints fur SOC with timing met, is being actively discussed. This paper suggests a methodology for SOC development by utilizing a top down flow via CWLM along with discussing potential problems. This paper also provides a design flow, including physical synthesis, DFT, floor plan and CWLM, all of which are relevant to proper SOC development.

Objective: The objective of the study is to develop a portable assistance device to help elderly users reduce strain on the knee and leg muscle while the elderly are standing up. Background: The pose of standing up from a chair is a basic movement, but the elderly often have difficulty standing up due to their weak muscles. We focus on designing a solution that helps the elderly reduce physical problems and support them standing up. Method: This study consists of three parts. Part I explores the way to reduce the refrain of leg muscle while standing up from a chair. In the process of structural development, we found that the moment is minimized when user pushes down the armrests due to a decrease in the force acting on the center of mass. In part II, a user test of 20 participants was carried out to rank the order of comfort of two stimuli: the chair with fixed armrests and the chair with the four-link mechanism that we created-in three different ways; (1) to stand up without touching armrests, (2) to stand up by pushing down on fixed armrests, and (3) to stand up by pushing down on armrests and being supported by the mechanism. To examine the statistically significant differences among the rank means, a Friedman test was conducted. In part III, we analyze the results of the user test and interview feedbacks, focusing on establishing a design strategy from UPO and visualizing it in 1:1 scale. Results: In part I, we decided to develop the four-link mechanism. The bottom is lifted up as the link rises. In part II, based on the rank data, we empirically found that UPO was assessed as the most comfortable during the stimuli. The thigh angle is smaller and the bottom of UPO is separated from a seat. In part III, after assessing the results and feedbacks, we created a visualization strategy for UPO: light, friendly, and novel. Conclusion: The portable and non-mechanical UPO comprises a four-link system that lifts the user's hips while standing. It can help users avoid knee and leg muscle strain. Its universal design considers the elderly's difficulties. Application: In a future study, combining light and durable material in UPO is expected to increase its usability. And this study is an opportunity to design various types of standing assistance devices.
