Computer system performance has always had the possibility of affecting business profitability, but with the advent of the World Wide Web where customers interact directly with Web servers, response time can have a direct and dramatic impact on business revenue. This paper is written in the operation environment and system analysis of HTS(Home Trading System) running K Securities. This paper also shows the method for performance improvement through investigation and analysis for the overall systems resources whether HTS has an appropriate performance or not. Performance analysis includes specially CPU analysis, Memory analysis, Disk Input/Output analysis and application analysis. Besides providing more detailed server specification for expansion from now on, system performance can be maintained with effect in the future. Through this study it is possible to manage the performance of HTS more easily and to solve problems such as a bottleneck more quickly.

국내 주식거래 시장에서 사용되는 홈트레이딩시스템(HTS)은 PC와 인터넷만 연결되어있으면 누구나 쉽게 내려받아 이용할 수 있는 주식거래 프로그램이다. 집에서도 이용할 수 있는 장점 때문에 증권회사별로 HTS를 만들어 배포하고 있으며 사용자의 편의성과 효용성을 만족하게 하려고 다양한 HTS를 개발하고 있다. 하지만 사용자 편의성에 중심을 두다 보니 아직 보안에 대해 미흡한 점이 발견되고 있고 이러한 취약점에 대해 보완을 하고 있다. 따라서 본 논문에서는 아직 보완해야 할 부분이 많은 메모리 영역에서의 보안취약점에 대해서 알아보고 이를 막으려는 대응방법을 제시한다.

최근 컴퓨터와 인터넷의 발달로 과거 창구거래를 이용하던 방법에서 HTS(Home Trading System)을 이용하여 거래하게 됨으로써 개인투자자들도 쉽게 주식투자를 할 수 있게 되었다. 그러나 개인들이 방대한 양의 과거 데이터를 분석하기에는 상당한 어려움이 있다. 본 논문에서는 주식 데이터베이스로부터 과거 특정 종목들 간 연관성을 추출하여 투자자들로 하여금 주식 선별에 참고가 될 수 있는 방안에 관하여 논의한다. 기존의 논문에서 제안된 과거 패턴을 이용하여 미래의 주가변화를 예측하는 것과 달리, 종목들 간에 연관성을 통하여 하나의 테마가 형성 되었을 때 주도주의 변화로 관련주의 변화를 파악하여 투자에 유익한 정보를 제공하는데 목적이 있다.

Modernization of cities and housing in Malaysia is a reflection of the history of the establishment of colonial trading ports for worldwide maritime trade and exchange. In cosmopolitan cities, new housing typology appeared from the influence of various ethnic immigrants and with the fusion of traditional Malay housing characteristics. This study is to focus on classifying the housing typologies of Malaysia which were formed through the modernization process of cities. The typologies of modern housing in Malaysia can be classified into two categories. The first category is the 'transformation of traditional housing'. The representative typology of this group is the ubiquitous shophouse. The shophouse was originally brought in by the Chinese immigrants from the south coast of China and transformed into the Malaysian urbanscape. The other typology is a detached-house known as the bungalo, which was the housing style combining the Malay traditional timber house and European palazzo. The second category is the 'modern urban housing typology'. Modern urbanization after the independence from the British in 1957 required the maximum utilization of land. To accommodate new social and economic needs, the new typologies were developed in the form of medium-density terrace houses (row houses) and high-density apartment. In the suburban areas, the British terrace house was adopted and developed into unique Malaysian terrace house and semi-detached house based on the British system of land sub division. In premium area of the city, luxurious housing type in the form of high-end condominium is one of the popular housing for upper middle-class and high-class society.

Uzbekistan, one of the top five cotton-producing countries in the world, primarily focuses its textile and fashion industry on raw cotton exports and the sewing industry. For Uzbekistan to achieve high added value, it is essential for the textile and fashion industry, which is currently at the CMT(cut, make, and trim) stage, to upgrade to OEM (original equipment manufacturing), ODM (original design manufacturing), and OBM (original brand manufacturing). South Korea recognizes Uzbekistan as a potential manufacturing base and trading partner and has invested Official Development Assistance (ODA) funds for the development of Uzbekistan's textiles and apparel sector. This study aims to evaluate Uzbekistan's fashion higher education in the context of global competitiveness and measure the need and prospects for education ODA from the Korean government in this field. Comprehensive investigations, including surveys of academics, industry experts, and government officials, in-depth interviews, and focus group interviews, were conducted to understand Uzbekistan's current fashion education environment. According to the research results, despite the textile and fashion sectors playing a pivotal role in the Uzbek economy, there is room for improvement in the curricula and teaching and learning methods of the fashion higher education programs. This study holds significance as foundational data for establishing education ODA strategies.

In order for Busan New Port to secure more trading volumes than the competing ports at home and abroad, an alternative plan for the new port management policy needs to be sought. By the way, aiming to minimize trial and error while maximizing effect in establishing and driving the new port management policy, there is necessity of referring to the developmental strategies of the advanced ports such as Singapore and Hong Kong that are possessing the globally leading position as well as maximizing the substantial value added and the employment-creation effect even qualitatively. Accordingly, the purpose of this study is to propose for a reasonable development strategy for Busan New Port in line with conditions and characteristics of Busan New Port by comparing and analyzing conditions and characteristics of these two advanced ports and by comparative analysis on the developmental strategy according to this.

Due to the overwhelming importance the Internet gained nowadays, more and more sophisticated security services are requested. However many applications such as Internet Banking, Home Trading System, Electronic Medical Recede, electronic commerce, etc. are related to non-repudiation. Non-repudiation services are one of these new security requirements. ill comparison to other security issues, such as privacy or authenticity of communications, non-repudiation has not been studied intensively. Informally, we say that a protocol is fair if at the end of the protocol execution either originator receives a non-repudiation of receipt evidence and recipient receives a non-repudiation of origin evidence or none of them receives any valid evidence. The most non-repudiation protocols rely on a trusted third party(TIP) that has to intervene during each protocols run. the TIP may create a communication bottleneck. ill this paper, we suggest the digital signature recorder that guarantees fairness logically and supplies minimal network bottleneck to be composed verification server physically.

Recently, the need for non-stop service is increasing by the business mission-critical Internet banking, e-payment, e-commerce, home shopping, securities trading, and petition business increases, clustered in a single database of existing, redundant research on high-availability technologies related to technique, etc. is increasing. It provides an API based on the Active Log in addition to the technique of redundancy, ALTIBASE$^{TM}$ Log Analyzer (below, ALA), provides scalability and communication of the same model or between heterogeneous. In this paper, we evaluated the performance of ALA by presenting the design of the database system that you can use the ALA, to satisfy all the synchronization features high scalability and high availability, real-time.
