This paper presents a method for the multilingual product retrieval agent through XML and the semantic networks in e-commerce. Retrieval for products is an important process, since it represents interfaces of the customer contact to the e-commerce. Keyword-based retrieval is efficient as long as the product information is structured and organized. But when the product information is expressed across many online shopping malls, especially when it is expressed in different languages with cultural backgrounds, buyers' product retrieval needs language translation with ambiguities resolved in a specific context. This paper presents a RDF modeling case that resolves semantic problems in the representation of product information and across the boundaries of language domains. With adoption of UNSPSC code system, this paper designs and implements an architecture for the multilingual product retrieval agents. The architecture is based on the central repository model of product catalog management with distributed updating processes. It also includes the perspectives of buyers and suppliers. And the consistency and version management of product information are controlled by UNSPSC code system. The multilingual product names are resolved by semantic networks, thesaurus and ontology dictionary for product names.

Companies that use a variety of software use patch management systems provided by security vendor to manage security vulnerabilities of software to improve security. System administrators monitor the vendor sites that provide new patch information to maintain the latest software versions, but it takes a lot of cost and monitoring time to find and collect patch information because the patch cycle is irregular and the structure of web page is different. In order to reduce this, studies to automate patch information collection based on keyword or web service have been conducted, but since the structure to provide patch information in vendor site is not standardized, it was applicable only to specific vendor site. In this paper, we propose a system that automates the collection of patch information by analyzing the structure and characteristics of the vendor site providing patch information and using web crawler to reduce the cost and monitoring time consumed in collecting patch information.

In the parts including a vehicle, standard and contents are different according to type of automobile. Although the parts are same, the quality and requirement all are different according to vehicle production version. Also the business is shared at each department in a production line. So if a part is changed, each team or the department must recognize information which is changed. But currently if the event can occur at like this each department, because of parts management through handwork, the unification of information is difficult. Therefore in this paper, we applied POP systems at the automobile part enterprise and constructed POP based the automobile part productive integrated management system. This system supported productive information from mechanical, equipment, worker, and products in real-time and data update also is processed automatically. When this system is introduced, work time and cost remarkably will be reduced.

데이터베이스와 연동하는 웹 응용에 대한 수요가 비즈니스를 포함하는 모든 분야에서 급속히 증가하고 있다. 그러나 급증하는 수요에 비해 웹 응용의 작성 및 유지.보수에 많은 시간과 노력이 소요되고 있다. 본 논문에서 소개하는 웹 데이터베이스 응용 자동 생성기 WebGen은 웹 응용에 필요한 폼들과 이 폼들을 통해 이루어지는 질의에 대해 데이터베이스와 연동하여 처리하는 웹 스크립트들을 자동 생성하는 소프트웨어 도구다. WebGen은 웹 응용 개발자가 작성하는 구성파일(configuration file)에 정의된 선언적인 내용을 스크립트의 기본 원형인 내장된 템플릿(template)에 반영하여 5개의 웹 스크립트들(Search, Select, Edit, Information, Action)을 생성한다. Action 스크립트를 제외한 나머지 스크립트들은 사용자 인터페이스로 각각 해당되는 웹 폼을 생성한다. 따라서 웹 응용 작성을 위한 시간과 노력을 크게 줄여 웹 응용의 생산성을 향상시킨다. 상용 웹 응용 생성기들과 달리, WebGen은 독립적인 템플릿을 기반으로 하기 때문에 버전 관리가 용이하고 한 폼에 표현 가능한 정보도 관심의 대상인 엔티티 외에 이 엔티티와 직.간접적으로 연관된 모든 엔티티들을 포함한다.

In software development process, appropriate design can exist more than one. And software architectures can be restructured by modification and update during design processes. Therefore, the method that specify efficiently the modification elements of architectures, and manage different versions of architecture designed through various aspects is required. In this study, we propose software architecture restructuring mechanism that can restructure legacy architecture and a new software architecture designed with reuse of it in integrated form, and define specification elements and structure of the proposed restructured architecture specification. It provides the method that can reference and reuse architectures designed with various aspects of developers in architecture design processes. In addition, it supports flexible specification method for specification of modification elements such as revision, substitution, update of legacy software architecture.

This paper proposes a computer vision and deep learning-based technique for surveillance camera system for vehicle counting as one part of parking lot management system. We applied the You Only Look Once version 2 (YOLOv2) detector and come up with a deep convolutional neural network (CNN) based on YOLOv2 with a different architecture and two models. The effectiveness of the proposed architecture is illustrated using a publicly available Udacity's self-driving-car datasets. After training and testing, our proposed architecture with new models is able to obtain 64.30% mean average precision which is a better performance compare to the original architecture (YOLOv2) that achieved only 47.89% mean average precision on the detection of car, truck, and pedestrian.

After examining the current situations of financial frauds and the reasons for their occurrence in the financial institutions through examples of financial frauds in domestic and abroad, this study presents ways to prevent such financial scams. The preventive measures consist of activities before and after the occurrence of financial frauds and during normal financial operations. The activities are as follows: 1. Preventive activity should be strengthened before the occurrence of financial frauds. That is, first, the enforcement of consistent internal control is needed. Second, in order to block the probability of financial frauds involved with employees, ethics education and a reward program for inside tippers need to be run. Third, financial institutions need to apply for comprehensive insurance policy to minimize the lost in case. 2. Preventive activity should be strengthened during normal financial operations. First, self authentication system for customers needs to be introduced. Second, dealings of day, week, and month need to be thoroughly checked and the system of audit needs to be expanded. Third, message service for the information on financial frauds and their preventive measures needs to be expanded. Fourth, public notification system against examples of financial frauds needs to be expanded. 3. Preventive activity after the occurrence of financial frauds should be strengthened. First, awareness for preventive measures such as imposing penalty on the manager needs to be enhanced. Second, strict restrictions on financial frauders such as a criminal charge needs to be strengthened. Third, there should be legal devices and resolutions in order to retrieve all the money deceived by financial frauds.
