As a new paradigm called modeling and simulation(M&S) or simulation based acquisition(SBA) has arisen, necessity of applying it to Korea has been increased. Not only rational construction of SBA but development of model which can evaluate driving results and improve relating processes to SBA is needed. Therefore we suggests the framework of capability maturity model for M&S development and SBA. The ultimate purpose of our model is improving processes relating to M&S development and SBA. The last section include detailed model which has practices for improving some SBA processes.

Stable and reliable air traffic service is required for users (aircraft pilot, air traffic controller, airlines and public) through enhancing capability related to airport operation and continuously improving air navigation system. ASMS (air navigation service provider (ANSP) safety maturity survey) is to determine the level of management and safety requirement such as organization, risk, policy, process, training and environment in Air traffic service field. We designed and developed the survey (26 study areas of management part and 23 study areas of safety part) considering global best practices (Eurocontrol and FAA) and customizing domestic circumstances with quantitative level assessment regarding management and safety issue of Air navigation system. The survey enables the performance of Air navigation system to enhance and prevents from occurring accident or incident. Therefore, we provides best information with users as well as high quality Air traffic service.

The recent studies indicated that the major sources of the failure in carrying out the programs of weapon systems development would be the unsatisfaction of the required key performance and also the use of premature technology. As such, to manage the risk during the weapon systems development, the use of the technical performance measurement (TPM) and the technology maturity assessment (TMA) turned out to be necessary. However, the TPM studied so far seems to cover the assessment of performance at the component level only, and thus is insufficient in considering the system integration effect. On the other hand, the system readiness level (SRL) method has been presented by reflecting the effect on system integration, but the system performance and maturity has not been considered. To overcome this, a measurement method is proposed in the paper by utilizing the combined system readiness level and achieved technical performance at the system level. This system performance measure can be useful in managing the risk in the weapon systems development.

SEI(Software Engineering Institute)의 CMM(Capability Maturity Model)은 소프트웨어 개발 공정 및 조직의 성숙도를 5개의 계층적인 단계로 분류, 평가하며, 성숙도 측정의 기준으로 계량적인 메저먼트를 각 단계별로 제시하고 있다. 본 연구에서는 CMM에 의해 제시된 메저먼트에 근거하여 정의되고 사용된 척도의 선정에 정보시스템 개발 및 품질 관리 기법인 QFD(Quality Function Deployment)를 적용하였다. 척도 사용자 그룹으로부터 CMM의 관심 영역, 사용 척도, 척도 계산에 필요한 측정치, 소프트웨어 개발 생명주기에 이르는 과정을 단계적인 흐름으로 파악하여 적절한 척도를 선택하는 데 본 연구의 목적이 있다.

최근 들어 보안사고의 대응 방식이 네트워크 보안이나 운영체제 보안과 같은 전통적인 방법에서 벋어나 개발생명주기보안이나 SW 공급망 보안으로 확대되고 있다. 이러한 흐름에서 주목받는 것이 BSIMM과 같은 소프트웨어 보안성숙도 모델이다. 보안성숙도 모델은 소프트웨어 시스템의 보안성 향상을 위해 관리자와 개발자가 중점을 두어야 할 부분을 스스로 평가할 수 있도록 하는 프레임워크이다. 본 고에서는 BSIMM을 통해 보안성숙도 모형이 갖는 특징을 소개하며, 이의 활용에 대해 살펴본다.

There are orthodontic treatment which involves tooth movements and orthopedic treatment which involves skeletal movement. In childhood and adolescence, especially for the treatment of orthopedic treatment, the evaluation of bone maturity and growth potential is very important. The purpose of this study is to assess the developmental stage and to compare the amount of mandibular growth with cephalometric radiographs and hand-wrist radiograph in 6 to 13-year-old children with normal occlusion. The results are as follows : SMI and CVM showed a significant correlation (p < 0.05). Ar-Go, Co-Go, N-Go, S-Gn, N-Me, Co-Gn, Go-Me, Go-Gn increased with increasing maturity of hand-wrist and Ar-Go, Co-Go, N-Go, S-Gn, N-Me, Co-Gn, Go-Me, Go-Gn increased with increasing maturity of cervical vertebrae maturation. Also Ar-Go, Co-Go, N-Go, S-Gn, N-Me, Co-Gn, Go-Me, Go-Gn showed a significant correlation with each of the cervical vertebrae maturation stages and hand-wrist maturation stages (p < 0.05). These results suggested that mandibular growth had a significant correlation with cervical vertebrae maturation stages and hand-wrist maturation stages.

DRM software should conform completeness, correctness and appropriateness for the related function to protect digital right properly. Therefore, the systematization of functionality evaluation method based on the related standard is essentially required. In this paper, based on the software quality standard, I intended to construct a model to measure the quality about functionality including suitability, accuracy and interoperability of DRM software. To this, we developed functional suitability evaluation model by analyzing infra-technology of DRM software and quality requirements about functional suitability. I think that through this study, functionality criteria to enhance the quality level of DRM software. Through the accumulation of future evaluation practices, it is necessary to improve the suitability and validity of the DRM software functional suitability evaluation model.

The purpose of study is for the certified correlations of hand-wrist radiograph with cervical vertebrae for skeletal maturation in children. Normal evaluation devices of growth stage is sexual feature, biological age, tooth development stage, height and weight. Evaluation of growth potential is very important for childhood and puberty. The skeletal developmental stages were evaluated by using the hand-wrist radiograph and cephalometric radiograph that obtained from 6 to 18 years old children. 1. Chronologic age was not more suitable indicator of skeletal development compared to Skeletal Maturity Indicators(SMI) and Cervical Vertebrae Maturation(CVM) stages. 2. SMI and CVM stages for females occurred earlier than that for male. 3. SMI 1 and 2 stages were corresponded to CVM 1; SMI 3,4 = CVM 2; SMI 5,6 = CVM 3. 4. Reproducibility and reliability of observer for SMI and CVM were excellent. This results suggest CVM stage is comparable to SMI stage in terms of evaluating the skeletal development.

소프트웨어 공학이 소프트웨어 시스템에 관한 방법론, 기술 및 툴 등의 유지보수와 개발에 중점을 두어 왔는데 최근에는 프로세스 개선과 프로세스 능력수준의 향상에 초점을 두는 방향으로 발전하면서 CMM 및 SPICE 활동이 증가하고 있다. 이와 같은 심사기법은 대규모의 회사에서 주로 시행되고 있어서 중소규모의 조직을 위한 간략한 심사기법의 도입이 요구되는 있는 상황이다. 본 논문에서 제시하는 심사기법은 CMM 심사를 위한 KPA 설문서의 rating 방법을 응용한 것으로서 SPICE 심사를 받은 국내 기업 중 일부 회사를 대상으로 하였다. 이 방법론에 대한 신뢰성의 평가는 아직 미흡한 상황이다. 이를 위해서 통계학적 접근방법을 도입하였는데 사용된 통계 기법은 상환계수를 통한 가설검정이다. 그 결과 성숙도 설문서(MQ) 선정모델의 적합성을 통계적 기법을 통해서 검증하였다.

This paper proposes a novel appoach which can assess the system technical maturity for use in Defense R&D Program reviews. As the weapon systems become more complicated, the success and effectiveness of R&D outcome heavily depend on the application and tailoring of systems engineering process and methods. It is a difficult task to assess the system readiness level(SRL) of the system being developed. A system-focused approach for managing weapon systems development and making effective and efficient decisions during the development lifecycle is critical to ensure the success of the program. The proposed weighted average SRL can facilitate the system technical maturity assessment without expending heavy work load.
