In Korea, fire is the second frequent disaster. A total of 32,966 fires were happened in 2002, and injured 2,235 people and damaged 12 million dollars. So, we developed several components related to fire in order to decrease these victims and the amount of damage and have applied those components to Daegu Fire Agency. In this paper, we describe the developing system. It consists of 5 major components: mobile fire facility management component, web service component, fire management component, fire server, and fire application. They were developed in object-oriented computing environment, ATL/COM and Visual C++. So, they have some advantages such as high reusability, full interoperability, and easy understanding.

One major development in bridge life cycle cost analysis (LCCA) in recent years is to develop deterioration model for bridge components so that the times of repair/replacement throughout a component's life span can be properly determined. Taiwan also developed her own bridge LCCA model in 2003, integrating with the bridge inspection database in the local bridge management system (T-BMS). Under the framework of the local LCCA model, this study employs the reliability method in developing a deterioration model of bridge components. A component deteriorates through time in its reliability, which represents the probability of a component's condition index exceeds a user specified threshold. Model assumptions and rationale are described in the paper. The steps for applying the developed model are explained in detail. Results and findings are reported.

To be dyed with cationic Berberine, the cotton fiber was modified with reactive anionic agent. The Berberine, a natural cationic colorant of pure yellow, is the major component of Amur Cork tree extract and also can be employed as a natural antimicrobial agent due to its characteristic of cationic quaternary ammonium salt. By LC/MS analysis, it became obvious that the Berberine was contained in Amur Cork tree extract as a major color component. The adsorption of the Berberine on the cotton fabrics pretreated with the anionic agent was greatly increased comparing to that of untreated fabric. Because the anionic agent was colorless, it did not cause unintended color change of the dyeings. The dyed fabric with the Berberine has strong antimicrobial activity showing 99.5% of reduction of bacteria against Staphylococcu aureus.

The zone conditional two-fluid equations are derived and validated against DNS database of a premixed turbulent flame. The conditional statistics of major flow variables are investigated to understand the mechanism of flame generated turbulence. The flow field in burned zone shows substantially increased turbulent kinetic energy, which is highly anisotropic due to reaction kinematics across thin f1amelets. The transverse component may be larger than the axial component for a distributed pdf of the flamelet orientation angle, while the opposite occurs due to redistribution of turbulent kinetic energy and flamelet orientation normal to the flow at the end of a flame brush. The major source or sink terms of turbulent kinetic energy are the interfacial transfer by the mean reaction rate and the work terms by fluctuating pressure and velocity on a flame surface. Ad hoc modeling of some interfacial terms may be required for further application of the two-fluid model in turbulent combustion simulations.

The inorganic compositions of traditional lye, and lyes prepared from the stalks of five different agricultural products: beans, wheat, barley, buckwheat and red peppers, were analyzed. Traditional lye was composed mainly of a weak alkaline salt, potassium carbonate as the major component and neutral salts, potassium chloride and potassium sulfate as minor components. The ash and lye contents of buckwheat have significantly higher then those of the rest agricultgural products. Bean and red pepper stalks lyes were composed mainly of potassium carbonate, similar to the composition of traditional lye, but also contained potassium chloride or sulfate. In contrast, postassium chloride was the major component of wheat and barley stalk lye.

Since Component-Based Development, or CBD, struck Korea SI industry a heavy blow several years ago, many major SI companies in Korea have implemented the CBD practices in real world, leveraging supports from the government and academic world. The result, however, falls short of their expectations. The major reason is that they have mainly focused on CBD processes and technical issues around it, although it is necessary as well to deal with other non-technical issues in order to make business values from CBD. This paper begins with reminding us what CBD tries to achieve indeed in terms of software development processes, then recognizes what we have achieved so far introducing a recent CBD project case, BOK-WIRE system. Thereafter, it reveals the chances that SI companies must take in order to make their CBD efforts succeed, pointing out what are the roadblocks really.

Mathematical formulation of the zone conditional two-fluid model is established to consider flame-generated turbulence in premixed turbulent combustion. The conditional statistics of major flow variables are investigated to understand the mechanism of flame generated turbulence. The flow field in burned zone shows substantially increased turbulent kinetic energy, which is highly anisotropic due to reaction kinematics across thin flamelets. The transverse component of rms velocities in burned zone become larger than axial component in the core of turbulent flame brush. The major source or sink terms of turbulent kinetic energy are the interfacial transfer by the mean reaction rate and the work terms by fluctuating pressure and velocity on a flame surface.

사전 제조된 컴포넌트들을 재사용하여 애플리케이션을 개발하는 컴포넌트 사용자의 관심사는 사용자의 요구사항에 따라 적절히 다른 컴포넌트들과 협동하는지 여부를 확인하는 것이다. 따라서 컴포넌트 기반 소프트웨어의 경우 개발 환경이 아닌 새로운 환경에서 소프트웨어를 구성하는 컴포넌트들이 잘 연동되는지를 테스트할 수 있는 상호운용성 테스트에 관련된 연구가 중요시되고 있다. 본 논문에서는 컴포넌트 기반 소프트웨어의 상호운용성 테스트를 위한 테스트 모델을 정의하고, 유스케이스 명세로부터 테스트 모델을 생성한 후 생성된 모델로부터 테스트 케이스를 생성하는 기법을 제안한다. 또한 테스트 모델로부터 테스트 시퀀스를 생성하는 프로시저를 구현한 도구를 소개한다.

Health promotion programs are becoming a vital component of comprehensive health care services worldwide for individuals and population, and health promotion activities have been a major component in advancing overall health of population. Promoting the health of individuals is akin to promoting the health of the community as these are closely linked to each other. Likewise, the health of every community in every state determines the overall health status of the Nation.(omitted)

A retrospective analysis was performed with 270 cases of canine urolithiasis examined at Laboratory of Clinical Pathology, College of Veterinary Medicine, Seoul Nat'l University in the period between January 2001 and December 2003. The Shih-Tzu (64 cases), Yorkshire terrier (60 cases), miniature schnauzer (41 cases) and maltese terrier (36 cases) had higher incidences than other breeds. Canine urolithiasis occurred from 4 months to 15 years of age, but the most prevalent age was 3 years. Mean age was $5.68\pm3.14$ years. The major mineral component. of calculi was struvite (54.1%) and calcium oxalate (30.4%). There was no sex prevalences: male 131 cases, female 132 cases. The most prevalent anatomic locations of calculi were urinary bladder (53 of 131 cases), urethra (24 of 131 cases) and bladder/urethra (45 of 131 cases) in males and urinary bladder (103 of 132 Cases) in females. The major mineral component of calculi in urinary bladder was struvite (102 of 160 cases), and that in urethra (13 of 25 cases) and multiple locations (29 of 62 cases) was calcium oxalate: The major components of calculi were not always consistent with the components which could be expected from urine pH and crystals. So it is suggested that the components of the calculi must be analyzed after surgical removal to prevent the recurrence when the calculi could not be dissolved by diets or urine pH modifiers.
