Since fairness issue has been found to be important in many different business contexts such as marketing, organizational psychology and management in general. The purpose of this exploratory study was to identify the factor structure of fairness and its effects on customer satisfaction and word-of-mouth. In this survey, we collected data from the respondents who have experienced online shopping from 61 online shopping companies. The data were analyzed by structural equation model using LISREL 8.5. The results indicated that fairness has a four-factor structure, which is composed of distributive, procedural, interpersonal, and informational fairness, which is different from three-factor structure. In addition, perceived justice as a second-order construct were found to have a positive effect on customer satisfaction and word-of-mouth intention. The study suggests that online shopping mall should increase customer satisfaction and positive word-of-mouth by enhancing multiple aspects related to fairness.

The threat to information security is growing globally. To this, organizations are increasing the weight of adapting and operating the more specialized information security policy and system. Information security requires participation from the employees who execute the security system and policy, and to increase the level of organization's internal security, requires organization's systematic support to improve employees' information security compliance intention. This research finds the mechanism for improving employee's information security compliance intention by applying justice theory and goal setting theory in information security. We use structural equation modeling to verify the research hypothesis, and conducted a survey on the employees of organization with information security policy. In other words, this research performs verification of the research model based hypothesis which claims that security policy goal setting has positive influence on employee's level of security related justice recognition, and claims that justice has positive influence on compliance intention. The object of study is the employees of the organization that adapts information security policy, and 383 valid samples were collected via survey. Structural equation modeling was performed to verify the research hypothesis. The result shows that security policy goal factor (goal difficulty, goal specificity) improves employee's security related justice recognition, and that security related justice (distribution, process, and information justice) has positive influence on compliance intention. The result suggests the strategic approach directions for improving employees' compliance intention on organization's security policy.

TFRC(TCF-friendly Rate Control) 혼잡제어는 연속적인 재생을 필요로 하는 멀티미디어 서비스를 위한 TCP-friendly 알고리즘이다. 이러한 TCP-friendly 알고리즘의 성능을 결정하는 가장 중요한 요인으로 기존 TCP 혼잡제어 알고리즘을 이용하는 트래픽과의 전송대역폭에 대한 공정성(fairness)이다. TFRC 혼잡제어 알고리즘에서는 이러한 공정성을 만족시키기 위하여 TCP를 모델링한 식에 의하여 전송률을 결정한다. 그러나 TFRC 혼잡제어는 혼잡이 심한 네트워크 상황에서는 공정성이 급격히 떨어진다. 본 논문에서는 TFRC 혼잡제어알고리즘의 전송률 결정방법의 개선을 통하여, 높은 손실률을 보이는 혼잡한 네트워크상황에서 공정성이 떨어지는 문제를 해결한다.

In recent years, many organizations protect their information resources by investing in information security technology. However, information security threats from insiders have not been reduced. This study proposes a method for reducing information security threats within an organization by mitigating negative information security behaviors of employees. Specifically, the study finds a relationship between information security related role stress and negative behavior and suggests whether organizational justice mitigates role stress. That is, the purpose of the study is to suggest a mechanism between organizational justice, information security related role stress, and negative behavior. Negative behavior consist of avoidance behavior and deviant behavior, and security related role stress consist of role conflict and role ambiguity. Organizational justice consist of distributional justice, procedural justice, and informational justice. The research model is verified through structural equation modeling. After establishing a research model and hypothesis, we develop a survey questionnaire and collect data from 383 employees whose organizations have already implemented security policies. The findings appear that security related role stress increases negative behavior and that organizational justice mitigates role stress. The results of the analysis suggest the direction of organizational strategy for minimizing insider's security-related negative behaviors.

Labor work information can be converted into the useful construction information in an effort to analyze project status, measure performance, and design a new similar project plan. The labor work information can also be used to make productivity data, which can be used to analyze the relationship between 'as planned' and 'as built' in scheduling management of a project, and to calculate 'percent completion' as well as analyzing delay cause. It is require to effectively collect the labor work information base on the activities. In general, current project management heavily depends on the experience and judgment of project managers, according to the work progress. However, relying on the oかy experience and judgment of the project managers might deteriorate the transparency or reliability of the collected labor work information. The purpose of this research is thus to develop a computer-based system for monitoring the work information generated by labors input in activities using PDA and Barcode technologies, and to propose a application method of the productivity data for effective project management.

반도체 공정은 웨이퍼를 제작할 때 오류가 발생할 경우 웨이퍼 전체를 사용하지 못하는 손실이 발생한다. 이로 인해 반도체 공정제어 소프트웨어는 높은 품질을 요구하고 있다. 반도체 공정제어 소프트웨어를 위한 테스트의 중요성도 높아졌다. 하지만 반도체 공정제어 공정제어 소프트웨어 테스트는 대상이 되는 프로그램에 따라 테스트 스크립트의 변화가 많다. 이로 인해 테스트 스크립트 작성의 비용이 높으며, 이미 작성된 스크립트의 재사용이 어렵다. 이러한 문제를 해결하기 위해 이 논문에서는 반도체 공정제어 소프트웨어를 위한 테스트 스크립트 생성과정과 생성된 스크립트의 재사용성을 높이기 위한 색인방법을 제안한다. 제안한 스크립트 생성과정은 반도체 공정제어에서 사용하는 일반적인 테스트 과정을 기반으로 스크립트 생성의 복잡도를 줄일 수 있다. 소프트웨어에 존재하는 함수의 수정으로 인한 스크립트 재사용성 불가 문제를 해결하기 위해 함수에 대한 정보를 색인하여 기존 스크립트의 재사용성을 높인다.

As protecting organizations' information assets affects their substantiality, they are increasing their investments in policies, regulations, and technologies for systematic information asset management and protection. This study confirms the impact on information security(IS) compliance from the perspective of employees who apply IS policies to actual work. In particular, this study identifies mechanisms linked to IS policy awareness, sanction, justice, and IS compliance from the perspective of expanding deterrence theory. We applied 316 samples obtained from workers of organizations that applied IS policies and regulations to work and verified the relationship between mechanisms by using AMOS and SPSS packages. As a result of the verification, IS policy awareness had a positive effect on organization justice and compliance intention through the severity and clarity of sanctions. Individual justice sensitivity had a moderating effect on the cause and outcome of justice. The sanction-related mechanism presented in this study provides strategic implications for organizations that require active IS activities by insiders.

본 논문은 멀티캐스트 혼잡제어방식 제안 중의 하나인 PGMCC의 공정성 향상 방법에 관한 것이다. 안정적인 멀티캐스트 전송과 혼잡제어를 위한 여러가지 방법중에서 PGMCC는 유력한 방식으로 제안되었다. 하지만 PGMCC에도 고정된 timeout 값의 사용과 불확실한 acker 선출로 인하여 공정성을 낮추는 요인들이 몇가지 지적되고 있다. 본 논문에서는 TCP와 같은 적응적인 timeout값의 적용과 acker 선출에서 추가적인 방법의 적용으로 이와 같은 문제를 해결하여 공정성이 향상되는 것을 확인 할 수 있었다.

The aim of this study is to investigate the role of information service failure severity within existing framework of service recovery justice research and analyse the effects of the attribution of service recoveries on recovered user satisfaction and revisit. For empirical analysis, A total of 452 valid questionnaires were used to analyse the data gathered from university students who experienced the information service failures of university library. Some findings of the research are as follows: First, service failure severity has negative effect on service recovery justice. Second, procedural and interactional recovery justice has positive effect on recovered user satisfaction. Third, service recovery justice has significant influence on procedural and interactional justice. Finally, recovered user satisfaction has positive effect on user revisit and mouth of word.
