소프트웨어 산업의 발전에 따라 소프트웨어 개발조직에서는 소프트웨어 품질이 중요한 이슈로 부각되었다. 특히 여러 종류의 테스트 성숙도 모델을 통해 조직의 소프트웨어 테스트 성숙도 향상에 대해 다양한 방면으로 시도하고 있다. 하지만 현재 테스트 성숙도를 측정할 수 있는 모델들은 기존의 개발 성숙도 측정 모델을 기반으로 개발하여 테스트 부분에 대한 언급이 부족하고 단지 테스트 성숙도 레벨만을 측정하였다. 이러한 문제점을 해결하기 위해 소프트웨어 개발프로세스와 한께 테스트 프로세스를 수행할 수 있도록 이중 V모델과 테스트 성숙도의 용이한 평가를 위한 테스트 평가 속성과 레벨을 정의한 테스트 속성과 상호관련 매트릭스를 제안하였다. 테스트 프로세스 개선(Test Process Improvement: TPI)의 개선제안(Improvement Suggestion) 방법을 통해 테스트 성숙도 모델 확장하고, 측정된 성숙도를 향상시킬 수 있는 개선방향을 제시한다. 또한, 본 연구에서 제안하는 테스트 성숙도 상호관련 매트릭스는 테스트 성숙도를 정량적으로 평가하기 위해 사용하였다. 결과적으로는 확장된 테스트 성숙도 모델을 통해 조직의 테스트 성숙도를 높이는데 기여 할 수 있으리라 생각한다.

Maturity models allow organizations to assess and compare their own practices against best practices or those employed by competitors, with the intention to map out a structured path to improvement. This research explores the aspects of the Maturity Models that are relevant to distinguish them from one to another. The different Project Management maturity models for define maturity differently and measure different things to determine maturity. Because of this, organizations should give careful consideration to select appropriate maturity model. The main reason behind this research lies on the modification to the existing Organizational Project Management Maturity Model (OPM3) by adding four knowledge areas, dedicated to construction industry as best practices. These are Safety, Environment, Financial and Claim Management. This Model contains (Yes/No) questions; all of these questions must be answered before the user reviews the results that describe the overall maturity and areas of strength and weakness of an organization. The research presents the implementation of the proposed Model Construction Enterprises Maturity Model (CEM2). All the components of the developed Model have been implemented in Microsoft Access. CEM2 helps Construction Enterprises to assess their Maturity Level and know Areas of Weaknesses for future improvement. The easy to use Yes/No user interfaces help enterprises' employees to assess the maturity level of their enterprises. The Model maintains users' responses in its database; as such, many employees from different enterprise divisions can be involved during assessment phase in several sessions.

This paper proposes an e-business maturity model for small and medium-sized enterprises. The model consists of five maturity levels, which are on-line access, on-line business, matured on-line business, and full on-line business from least matured level to most matured level. The model can be used to assess e-business maturity level of individual enterprises. individual enterprise's maturity level can be assessed by examining sample check lists. Additionally, this paper summarizes the results of an application of the proposed model to a couple of small and medium-sized enterprises. This model can also be used to suggest what individual enterprises need to be upgraded towards higher maturity level.

소프트웨어 아키텍처는 소프트웨어 집중적인 시스템의 가장 주요한 부분으로, 아키텍처 평가는 시스템에서 매우 중요한 과정이고 소프트웨어 재앙을 예방할 수 있는 가장 저렴한 방법이다. 본 논문은 성숙모델을 통하여 아키텍처를 평가하는 새로운 방법을 소개한다. 기존의 성숙모델들은 소프트웨어나 소프트웨어 프로세스에 관한 것으로 지금까지 빠른 속도로 발전되어 왔다. 본 논문에서는 이러한 기법들을 소프트웨어 아키텍처에 적용한 SAMM(Software Architecture Maturity appraisal Model)을 제안한다. SAMM은 여섯 등급으로 구성되어 있다 제안한 성숙 모델 SAMM은 시스템 개선을 관리하는 발전된 아키텍처를 구성하고 소프트웨어 아키텍처 설계를 개선하기 위해 필수적으로 요구되는 아키텍처 요구사항들을 명세한다. 또한, 아키텍처 설계를 위한 노력을 줄이고, 질 높은 아키텍처를 구성할 수 있는 지침을 마련해주며, 아키텍처를 평가하여 등급을 매긴다.

At a time when children of multicultural families have begun to enter adolescence in Korea, this study examined the effects of parental support and bicultural acceptance on the career attitude maturity of multicultural adolescents. This study tried to derive the implications related to the career path of multicultural adolescents by verifying the effects of self-esteem on the relationship between parental support, bicultural acceptance, and career attitude maturity. Using the 8th Multicultural Adolescent Panel Survey data (MAPS), the relative influence of antecedent variables on career attitude maturity was confirmed by hierarchical regression analysis of the data from 1,197 respondents. Model 1 included gender and parental support, Model 2 added bicultural acceptance to Model 1, and Model 3 added self-esteem to Model 2. As a result of the study, in Model 1, women had higher career attitude maturity than men, and the more supportive their parents were, the more positive the level of career attitude maturity. The adjusted R2 of Model 1 was .058, which did not have much influence. In Model 2, gender, parental support, and bicultural acceptance had statistically significant effects on career attitude maturity, and the amount of change in F was also significant. The adjusted R2 of Model 2 was .132. In Model 3, parental support was not statistically significant, and gender, bicultural acceptance, and self-esteem had statistically significant effects on career attitude maturity. The amount of change in F was statistically significant and the adjusted R2 was .185. That is, it was confirmed that the more the women, the more the bicultural acceptance, and the higher the self-esteem, the more prepared and determined the career path. Based on the research results, the implications related to career preparation of multicultural adolescents were presented.

There are no objective standards for selection and improvement of SLA evaluation metrics for IT service. In this study, we analyze the current IT maturity models for selection and improvement of the metrics and then we derive them according to the maturity levels and propose the redesigned maturity model. To verify whether the model is applicable, we execute a case study based on the D company. We apply the proposed evaluation metrics of the maturity models to the D company and evaluate the metrics. We select a proper level of the D company and an improvement line after measuring evaluation metrics in the maturity level 2. We propose improvement guidelines of evaluation metrics which score is less than the improvement line's and derive SLA evaluation metrics. By using the SLA evaluation metrics for a year, we prove that the way of selection and improvement is useful.

This paper proposes a model to assess the maturity level of Six Sigma activities. We classify the maturity level into 5 stages: initial, forming, storming, performing and mature stage. To evaluate the maturity level, 10 categories of Six Sigma with 3 factors each are identified: management leadership, belt system, expert training, establishing execution system, compensation, organization, corporate culture, customer focus, project selection, and management of project results. Scoring 277 items in total, the value of each factor is evaluated by weighted average of those items. Maturity level is appraised by rating the sum of scores of 10 categories that are obtained by summing up the values of its 3 factors. Values of weights and criteria of rating maturity levels are determined by analyzing 90 companies and Six Sigma exper's opinion. This study also shows the actual appraisal results of some companies.

Approximating the implied volatilities and estimating the model parameters are important topics in quantitative finance. This study proposes an approximation formula for short-maturity near-the-money implied volatilities in stochastic volatility models. A general second-order nonlinear PDE for implied volatility is derived in terms of time-to-maturity and log-moneyness from the Feyman-Kac formula. Using regularity conditions and the Taylor expansion, an approximation formula for implied volatility is obtained for short-maturity nearthe-money call options in two stochastic volatility models: Heston model and SABR model. In addition, we proposed a novel numerical method to estimate model parameters. This method reduces the number of model parameters that should be estimated. Generating sample data on log-moneyness, time-to-maturity, and implied volatility, we estimate the model parameters fitting the sample data in the above two models. Our method provides parameter estimates that are close to true values.

Many previous studies of data quality have focused on the realization and evaluation of both data value quality and data service quality. These studies revealed that poor data value quality and poor data service quality were caused by poor data structure. In this study we focus on metadata management, namely, data structure quality and introduce the data quality management maturity model as a preferred maturity model. We empirically show that data quality improves as data management matures.
