소프트웨어 개발 프로젝트에서 메트릭 수집 및 분석 활동이 점차 중요하게 인식되고 있다. 메트릭 수집 및 분석 활동은 조직/프로젝트, 팀, 개인 모든 레벨에서 수행되어야 하는 중요한 활동으로 여겨져 오고 있다. Personal Software Process(PSP)[1]에서 개발자 개개인이 수행해야 되는 메트릭 수집 및 분석 활동이 제시된다. 이러한 메트릭 수집 및 분석 활동을 통해 개발자는 소프트웨어 품질 향상, 계획 단계에서 보다 정확한 예측 활동, 개인 프로세스의 정량적 관리 등의 이득을 얻을 수 있다. 이러한 이득을 얻기 위해서는 신뢰성 있는 메트릭 데이터의 수집이 무엇보다 중요하게 된다. 그러나 메트릭 수집의 오버헤드와 context switching 과 같은 문제로 인해 개발자가 신뢰성 있는 메트릭을 수집하는데 많은 어려움이 겪는다[2, 3]. 또한 PSP 가 제시하는 분석 기법만으로는 수집된 메트릭에 대하여 의미 있는 분석을 하기 어려운 문제점이 존재한다. 이러한 문제점들을 감소 시키기 위해 메트릭 수집 및 분석 도구를 개발하였고 본 논문에서는 이 개발된 도구를 설명한다. 이 도구의 핵심은 메트릭의 자동 수집과 다양한 분석 결과의 제공을 통해 신뢰성 있는 메트릭 데이터의 획득과 의미있는 분석을 가능케 하는 데 있다.

This study investigates the impact of privacy concerns, perceived utility, and awareness of the right to personal data self-determination on the effective use and expansion of MyData services, which are critical to the data economy. Integrating the value-based adoption model with privacy calculus theory, the research examines how perceived utility, privacy concerns, trust, and personal innovativeness influence perceived value, perceived privacy, and the intention to provide personal information. Data collected from an online survey of 442 MyData service users and prospective users were analyzed using PLS-SEM and Bootstrapping methods via SmartPLS 4. The results indicate that perceived utility positively affects the intention to provide personal information, while privacy concerns have a negative impact. Trust and personal innovativeness positively influence the intention to adopt MyData services, and the awareness of personal data self-determination rights moderates these intentions. The findings underscore the importance of developing beneficial services that mitigate users' privacy concerns and build trust for the successful implementation of MyData services. Additionally, the study highlights the need for education and awareness campaigns to enhance understanding of the right to personal data self-determination.

This study empirically analyzes casual relationships among psychological and financial factors influencing the subscription of individual pension and identifies mediation effect by the structural equation model. The analysis based on survey data (N=928) from common people living in the seven major cities in Korea shows that potential longevity, coping efficacy to the financial risks from longevity, subjective knowledge on longevity (cognitive factor), trust in insurers (social factor), and financial literacy(financial factor) are key players exercising direct influence over the subscription of individual pension. It also has been shown that affect on longevity, potential longevity, trust in government, and coping efficacy influence the emotions on longevity, fear and worry, and emotions on longevity are not significant in explaining the subscription of individual pension. Trust in insurers and financial knowledge of prospects have also been reaffirmed to be crucial factors in the activation of individual pension subscription.

The use of the Internet is spread over all areas of our lives. However, its features raised serious social issues due to unethical behavior. To understand the level of Internet ethics among undergraduate students, a survey questionnaire of 31 questions regarding netiquette awareness, ethical norms, information credibility, and personal background is devised; data was collected from 830 students. Descriptive analysis shows low level of netiquette awareness, considerable deviation from six categories of ethical norms and problems of network information credibility. Results of statistical testing show gender and grade level as factors affecting Internet ethics. However, there is no significant difference in Internet ethics depending on related education experience. Based on the results, recommendations to promote Internet ethics are suggested.

Drawing on Protection Motivation Theory(PMT), this study attempts to clarify antecedents that influence the intention to protect individuals' privacy on the Internet. Protection motivation forms through individuals' cognitive appeal involving threat and efficacy. Then protection motivation causes privacy behavioral change. Protection motivation factors are established privacy trust and privacy risk, which are related to privacy attitude and belief. This proposed model is empirically analyzed by utilizing structural equation analysis(SEM). According to the result of the empirical analysis, it is founded that almost paths have statistically significant explanatory power except path from efficacy to privacy risk and path from privacy trust to privacy behavioral intention. This study shows powerful evidence of antecedent factors based on protection motivation of individuals' privacy behavioral intention in online environment.

As business marketers placed greater emphasis on building long-term relationships, trust has assumed a central role in the development of marketing theory(Dwyer, Schurr, and Oh 1987; Mogan and Hung 1994) and practice(Dertouzos, Lester, and Solow 1989). Marketing research on trust primarily focuses on two targets of trust: supplier firms and their salesperson. Trust of firm and trust of salesperson, though related, represent different concepts(Doney and Cannon 1997). Also, the definition of trust proposed by Ganesan(1994) reflects two distinct components: (1) credibility, which is based on the extent to which the buyer believes that the seller has the required expertise to perform the job effectively and reliably and (2) benevolence, which is based on the extent to which the buyer believes that the seller has intentions and motives beneficial to the buyer when new conditions arise, conditions for which a commitment was not made. The existing marketing research focuses on how trust of a firm and its salesperson has a differential effects on loyalty. However, these extant research pays little attention to the moderating effects that explicitly examine how two trust dimensions of salesperson(credibility and benevolence) affects loyalty of firm. The purpose of this study is to provide new insight into boundary conditions(individualism and industry type) that credibility and benevolence influences loyalty.
