Some local governments in Korea are currently developing various Urban Information Systems (UIS) to computerize their work. But they have spent too much money on their own UIS development because they have not reused the existing UIS of others. It has caused the central government to invest money repeatedly. The work of some local governments is generally very similar to those of others. The purpose of this paper is to suggest a solution to the reinvestment problem. To solve the problem, this paper suggests that they could model a city's business using Unified Modeling Language and Component-Based Development Process (CBD). They could also develop a UIS from the existing models, and then other municipalities can reuse the developed UIS. This paper illustrates the water supply business of P City in Korea and Rational Unified Process as a CBD. This paper also describes methods to apply CBD, to establish a reusable business model, analysis model, and design model, and to develop the software components of ActiveX Controls form for the water supply business.

It is important to operate an education resources which could be integrated to an system. But most of existing education information system was not developed with standardization. It is need the core education asset and reusable education service to make a good education system. Consequently, it is needed to use Sharable Content Object Reference Model(SCORM) based contents managing in order to reuse the contents of education. And it needs assembling and producing method with reusable core asset of education system to develop the application program for education. In this thesis, we study the Teaching-Learning supporting system to support systematic education resources. Teaching-Learning support system is developed of educational domain assess through development process based on Model Driven Architecture(MDA) and core asset on each stage. Application program of education is developed using MDA automatic tool through analyzing and designing for contents storage which is based on contents meta model. We finally can develop the application software of education with low cost and high productivity by raising the reusability of education contents and by using the core asset to the whole development process.

Reusing of electroless Co-Cu-P waste solution was investigated in the respect of plating time, plating rate, solution composition and deposit. Plating time of cobalt-catalytic surface took longer than that of zincated-catalytic surface. It was possible to reuse the waste solution by mixing $50\%$ fresh solution at batch type. Plating time of initial solution at continuous type took longer 7.5 times over than that of batch type. Plating time of $50\%$ waste solution additive at continuous type took longer 2.5 times over than that of batch type. Component change of cobalt-topper for electroless deposition was greatly affected by deposit inferiority and rapid decrease in plating rate.

In recent years, the development of ubiquitous computing technology as vital information anytime, anywhere to monitor and manage the demand for U-healthcare services is increasing. Accordingly, remote blood sugar management, remote blood pressure management, and research on U-healthcare service have been very active. But, the existing U-healthcare service monitoring devices and services has been implemented in different operating platforms and programing languages which are provided by diverse application service providers. For this reason, the users have difficulty in receiving diverse U-healthcare services. In this paper, SOA-based U-healthcare monitoring system has been designed and implemented. Through implementation, it is confirmed that the proposed SOA based U-healthcare monitoring system can increase the reuse of each service component to make it easier to reconstruct the structure of the new services.

Systematic modeling methods. which can correctly represent user requirements, are absolutely required to extract components when developing components. But, components are designed and developed In general based on the concept of object modeling so that they lacks in supporting representing cooperation and interaction as well as reuse. It means extracting components is not easy to be applied to complicated and sophisticated large-scale systems. This paper utilizes a role modeling method based on the role of objects, not on objects themselves, to complement object modeling. The Role modeling can break down a complicated system into simple models through abstracting the pattern of objects based on roles of the objects. In this study, an UML-based method extracting components through role modeling is embodied. UML can represent models from various standpoints so that role models arc also viewed from several points of view.

For the purpose of reuse the wasted by-products from the skate process to the health functional food or medicinal material, chondroitin sulfate was extracted from the skate cartilage with the method of hydrolysis with protease enzyme, and the contents of chondroitin sulfate and hydrolyzed protein were measured qualitatively and quantitatively. The effects of chondroitin sulfate on body weight or liver weight changes, hepatotoxicity elimination and anti-inflammatory actions were measured from in vivo test with feed-treated mice. From the hydrolytic extraction of skate cartilage with the mixture of 1% alcalase and 1% protease for 4 hours, the extraction yield of chondroitin sulfate was about 32.55%. The content and molecular weight of chondroitin sulfate was 26.63% and $2.85{\times}10^5Da$., respectively and the content ratio of chondroitin sulfate to protein was measured to 1 to 2.76 with gel permeation chromatography. For the odor component, trimethylamine decreased about 30% but almost not ammonia from chondroitin sulfate with the treatment of activated carbon. From the feeding chondroitin sulfate to mice, the control effect of body and liver weights decrease was measured, anti-inflammatory action and hepatotoxicity elimination action were also measured. From these results, process operation conditions for manufacturing of chondroitin sulfate were suggested.

The current status and prospect of decommissioning technology development at KAERI are reviewed here. Specifically, this review focuses on four key technologies: decontamination, remote dismantling, decommissioning waste treatments, and site remediation. The decontamination technologies described are component decontamination and system decontamination. A cutting method and a remote handling method together with a decommissioning simulation are described as remote dismantling technologies. Although there are various types of radioactive waste generated by decommissioning activities, this review focuses on the major types of waste, such as metal waste, concrete waste, and soil waste together with certain special types, such as high-level and high-salt liquid waste, organic mixed waste, and uranium complex waste, which are known to be difficult to treat. Finally, in a site remediation technology review, a measurement and safety evaluation related to site reuse and a site remediation technique are described.

The aim of this study was first to expand participation types in the field of beauty design by examining activities in the field, and second, to seek practical methods for addressing the important issue of social responsibility amid the current pandemic situation. Accordingly, social responsibility in design was examined through a review of previous studies. The features of practice domains and design performance fields were examined comparatively. As a result, it was found that social practices take place in various sectors, with sensibility toward the environment being escalated to a new level in the cosmetics industry. In terms of cosmetics enterprise practices, collecting, recycling, manufacturing, and retail networking has been established to reuse up to 95% of waste resources. Furthermore, ethical responsibility and participation concerning product and service waste resources are recommended, resulting in the supply of eco-friendly products in a virtuous cycle. In terms of systematic policy, even component transformation (such as organic certification and excluding toxic substances) is being carried out. However, it was difficult to identify such responsible activities in Korea; thus, systematic practice is needed. Designers take part in talent donation activities, and it was the sector they prefer the most. However, it is necessary to conduct studies on limitations such as venues equipped with cosmetics procedure equipment and public cosmetics sanitation and make systematic improvement, such that activities can be led with initiative from passive participation.

Use of recycled aggregates in portland cement concrete construction can offer benefits associated with both economy and sustainability. Testing performed to date indicates that RBMA can be used as a 100% replacement for conventional coarse aggregate in concrete that exhibits acceptable mechanical properties for use in structural and pavement elements, including satisfactory performance in some durability tests. RBMAC is currently not used in any type of construction in the United States. However, use of RBMAC could become a viable construction strategy as sustainable building practices become the norm. Rating systems such as LEED offer points for reuse of building materials (particularly on-site) and use of recycled materials. If renovations at an existing facility call for the demolition of existing brick masonry constructions, the rubble could be included as RBMA in new concrete pavement, sidewalks, or curb and gutter. Other potential uses for RBMAC could include those in the precast concrete industry, particularly in architectural precast concrete applications. In addition to providing acceptable strength and economy, the color of RBMA could be an attractive component of architectural precast concrete panels or other façade components. This paper explores the feasibility of use of RBMAC in several types of sustainable construction initiatives, based upon the findings of previous work with RBMAC produced from construction and demolition waste from a case study site. Guidance for obtaining and using RBMA is presented, along with a summary of material properties of RBMAC that will be useful to construction professionals.

In this paper, we propose the standard architecture for the IFF interface SW in naval combat management system(CMS). The proposed standard interface architecture is a method designed to reduce modification efforts and man-month of reliability test for the existing the IFF interface SW of 11 types. We identified highly dependent CMS and GFE information, leading to the redefinition of standard requirements and functions, and proceeded with the initial design applying the Naval Shield Component Platform(NSCP). Subsequently, using the Feature Model, we derived additional common and variable elements for the interface of multiple CMS and GFE. Considering the S.O.L.I.D principles, we designed the final architecture. The proposed IFF Interface SW, based on the standard architecture, is expected to enhance management efficiency through a common architecture, increase code reusability and scalability, and reduce development costs by shortening reliability testing times.
