The purpose of this study to develop IT Outsourcing service quality evaluation measurement have been frequently used to apply a model KS-SQI in the service industry. Primary needs fulfillment, unexpected benefits, reliability, individual empathy, positive assistance, accessibility and physical environment were selected as independent variable, they evaluate IT outsourcing service quality in order to verify their suitability as a tool for IT outsourcing service evaluation measurement, to analyze how that affects IT outsourcing satisfaction, and to investigate whether affecting IT outsourcing satisfaction on recontract intentions. To validate the hypothesis by path analysis conducted between variables using LISREL, primary needs fulfillment, reliability, individual empathy, positive assistance, accessibility and physical environment have significant effect on IT outsourcing satisfaction, but unexpected benefits don't have effect on IT outsourcing satisfaction, and IT outsourcing satisfaction showed significant effect on recontract intentions. Six Measurement tools has been proved to be suitable as a IT outsourcing service quality evaluation tool. Contribution of this study to evaluate the quality of IT outsourcing services, KS-SQI model developed by applying the measuring tool was achieved theoretical extensions and practical aspects of a recontract with the provider of IT outsourcing and IT outsourcing services for as a tool to assess the quality of can be used.

Recently, in order to build a cyber threats have increased in number and complexity. These threats increase the risk of using personally owned devices for work. This research addresses how to utilize an AI-enabled breach analysis tool. To this end, we developed and proposed the feasibility of using an AI-based breach analysis tool that reduces the workload of analysts and improves analysis efficiency through automated analysis processes. This allows analysts to focus on more important tasks. The purpose of this research is to propose the development and utilization of an AI-based breach analysis tool. We propose a new research direction in the field of breach analysis and suggest that automated tools should be improved in performance, coverage, and ease of use to enable organizations to respond to cyberattacks more effectively. As a research method, we developed a breach analysis tool using A.I. technology and studied various use cases. We also evaluated the performance, coverage, and ease of use of automated tools, and conducted research on predicting and preventing breaches and automatically responding to them. As a result, this research will serve as a foundation for the development and utilization of AI-based breach analysis tools, which can be used to respond to cyberattacks more effectively through experiments.

In a program that runs an engineering education certification, program outcomes refer to the knowledge, skills, and attitudes a student must have until graduation. In general, capstone design is used as a tool for evaluating program outcomes. This paper applies the intraclass correlation coefficient (ICC) to measure the raters' reliability in assessing program outcomes. Several raters evaluate program outcomes, and the result is used to obtain the raters' ICC. ICC measures the reliability of ratings or measurements for clusters - data that has been collected as groups or sorted into groups. If the ICC is close to 1, it means that the reliability among the raters is high. We evaluated the proposed method's usefulness through case analysis. As a method for assessing an evaluation tool's objectivity, multiple raters measure the same evaluation tool. As a result, we measured the ICC values for all POs, and analyzed the cause for the low measured POs. We applied this method to evaluate program outcomes of the Department of Computer Engineering in the past two years. As a result, we derived guidelines for improvement and program outcomes.

디자인의 여러 프로세스중 중요 행위는 사용자가 바라는 점을 파악하여, 제안하는 행위 중심으로 이루어진다. 사용자의 니즈를 파악하는데 있어, 사용성 평가를 활용하면, 논리적이고, 구체적인 불편요소를 파악하는데 도움을 받을 수 있다. 또한, 디자인 개선안의 효용성을 파악하는데도 디자이너에게 유용한 디자인 개발 프로세스로 자리 잡았다. 사용성 평가를 통해 사용자의 불편요소를 파악하는 방법으로는 크게 두가지 방법이 있는데, 하나는 데스크 탑 컴퓨터를 활용한 시뮬레이션 기법을 들수 있고 다른 하나는 모바일 폰을 활용하는 모습을 직접 촬영하여, 분석하는 방법을 들 수 있다. 데스크 탑 컴퓨터를 활용한 시뮬레이션 기법은 화면의 해상도와 인터렉션 방법이 상이하고, 직접 촬영 방법의 경우, 피 시험자가 카메라를 의식하거나, 분석상에 연구자의 바이어스가 개입할 여지가 많아 각각의 단점이 있다. 본 연구에서는 디자이너가 해결안을 프로토타이핑 하는 방법으로 모바일 폰의 프로세서를 활용한 로그를 남기는 방법으로 사용성 평가를 진행할 수 있는 도구를 만들고 이를 통한 사용성 평가 기법의 방안을 제안하였다. Mobile phone 의 Software User Interface 의 개선안을 검증할 수 있는 툴로 제작된 Interactive Mobile Phone Logger 라는 프로그램을Visual Basic 과 JAVA를 이용하여 개발하였다. 이를 활용하면, 디자이너의 해결안을 자동으로 JAVA Class 파일의 패키지로 생성해주고, 서버를 이용하여 패키지를 전송, JAVA를 지원하는 모바일 폰이면 어떠한 모델이든 실험에 참가할 수 있도록 제작 되어있다. 또한, 실험의 결과 데이터는 종료시 자동으로 실험자의 서버를 통해 분석될 수있도록 제작되었다.

There are life-style and many different cultural differences between countries. Among them, food is different from other areas. Especially, if Food Tools are used by food type, even though the design factor is same, the function is different. Therefore, research and development of a Food Tool design is necessary to use a Universal Food Tool between countries. The purpose of this research is to develop a behavior analysis process for food, finding similarities and differences by food type; and cultural differences between countries; and to propose a design Food Tool design that can be used between countries. This research on methods and content is for the development of the consumer behavior analysis process about food, grafting theoretical studies about behavior analysis and working behavior analysis on the spot, to develop a food action analysis process. Second, do comparative analysis process of food order and evaluation between countries; and think about the problems and symptoms, then propose methods to resolve the problems. Third, each process is divided by category, to find the features by each category of foods between countries. Results may be obtained through research and the comparative analysis of each country's, foods, behavior and restaurant types. Specifically, researchers can use food tool design to obtain results and compare the same items between countries, compare university design education, and create new ideas through cooperation and complementary research.

최근 많은 관심을 끌고 있는 지문인식시스템은 사용자의 지문영상을 입력 받아 사전에 등록된 템플릿과 비교하여 사용자 여부를 확인하는 사용자 인증 도구이다. 지문을 입력 받기 위한 센서와 매칭 알고리즘 등이 활발히 개발되고 있으며, 실제로 전자상거래나 출입통제시스템 등의 많은 분야에 적용되고 있다. 지문인식시스템에 대한 기존의 평가는 수집된 지문 DB 에 대해 인식 성능이 얼마인지, 쌍둥이들을 잘 구분하는지, 위조 지문을 파악할 수 있는지 등 주로 지문인식 자체의 성능에 초점이 맞추어져 있었다. 하지만 지문인식은 사용자나 환경과 관련된 많은 요인에 영향을 받기 때문에, 시스템을 효과적으로 적용하기 위해서는 이들에 대한 분석이 필요하다. 지문인식시스템에 대한 사용성 평가는 시스템이 대상환경에 효과적으로 적용되도록 하고, 사용성 분석을 통해 보다 편리하고 효율적인 사용자 인터페이스의 개발을 유도한다. 본 논문에서는 지문인식에 영향을 주는 요인을 사용자와 시스템 측면에서 분석하고, 사용성 평가를 통해 효과적인 지문인식시스템 인터페이스 구축을 위한 가이드라인을 제시한다.

Currently, usability tests for web sites with representative users are conducted in laboratory environment that disturbs subjects' natural behavior. These test methods are inefficient for tests that require large number of subjects, because experimenters and subjects should be located in the same place at the same time during the test. In this study, a remote usability test tool, called 'RIO' has been developed to cope with these laboratory-based experiment problems - the 'synchronism' and the 'unnatural environment'. The tool is separated into three parts: 'Project Manager', 'Remote Interaction Observer', and 'Interaction Analyzer'. 'Project Manager' sets up overall experimental parameters and actual tasks to be peformed by subjects. 'Remote Interaction Observer', endued with Microsoft Internet Explorer Control, is a modified Web Browser which records user interactions, screen images and elaborate browser events while subject performs given tasks. This module is distributed to subjects as an installable software package. When they finish all the tasks, the captured interaction data is compressed and sent to 'Interaction Data Server' automatically. 'Interaction Analyzer' visualizes interaction data from the 'Interaction Data Server'. It also generates project-scope statistics which facilitate discovering peculiar cases among interaction submissions.
