유기 분자들은 대부분 전기가 잘 통하지 않아, 그 응용이 매우 제한적이었으나, 1985년의 C. W. Tang 교수의 다층 구조 전자소자의 보고를 기점으로 급격한 발전을 이루었다. 현재는 유기분자를 이용한 디스플레이인 AMOLED(아몰레드)를 적용한 스마트폰, TV등이 상용화 되었을 정도로 기술 성숙도가 매우 높아졌다. 그러나 여전히 분자 시스템에서의 전하 수송에 대해서는 하나의 정립된 모델이 없다. 일례로, 밴드 수송과 호핑 수송 등 두 가지 다른 전하수송 특성이 보고되고 있다. 본 발표에서는 계면 에너지레벨 접합과, 분자층 내부의 분자간 상호작용(호핑 수송 위주로) 측면에서 분자 시스템의 전하 수송에 대해 논의한다.

The recently developed military system adopts System Engineering for quality insurance. The process of military system's development basically adopts specification(MIL-STD-499) and system engineering(ISO/IEC 15288) that was developed by America. Recently the level of company's capability maturity is granted by measurement and assessment for the level of CMM or CMMI that was developed by Carnegie Mellon University. This article introduces adopted range of process that developed military system adopted additional process of CMMI. This article writes a merit of process for military system's output that is developing device adopted diverse process.

It is being emphasized that management of core process is another crutial factor in the development of a product, besides of management of quality factors for the product itself. The study purposes to introduce process quality concept to digital contents market, and also aimes at meauring of process maturity, based on level 2 and 3 of Capability Maturity Model, for domestic companies especially devoted to digital contents area. The result shows that the maturity level of most of companies surveyed is very low and that mobile and game fields are slightly more matured than animation field. The paper also proposes some of future efforts to be made fur improving maturity level of digital contents companies.

The Korean government developed an organizational maturity model for public data quality management based on international standards to evaluate the data quality management level of public organizations, However, as the model has too many indicators to apply on the site, a new model with reduced number of indicators is proposed in this paper. First, the number of processes is reduced by integrating and modifying the processes of the previous model. Second, a new maturity evaluation method is proposed based on capability levels focused on the activity, not on the process. Third, the maturity level of public data quality management is represented by five discrete levels or real values of 1 through 5. Finally, characteristics of the proposed model are compared with those of the previous model.

21세기에 들어서면서 급속도로 성장한 한국의 게임 산업은 어느덧 국내에서 성숙기 단계를 맞이하고 있다. 또한 게임 산업의 꾸준한 확장을 위해서는 글로벌 시장에서 인정받을 수 있는 게임 개발이 절실히 요구되고 있다. 본 논문은 이를 위한 한 단계로서 MMORPG 장르의 게임 중에 오랫동안 이 분야에서 성공 가도를 달리고 있는 월드오브워크래프트를 몰입도 관점에서 성공 요인을 분석하고, 이를 바탕으로 2011년도에 주목 받고 있는 신생 게임 테라의 특징을 동일한 관점에서 분석한다. 몰입도 분석 방법은 정보이론과 정신물리학에 기반하며 게임의 레벨과 스킬의 개수에 의존적인 함수로서 정량적인 접근 방법을 제안한다. 제안 방법에 따르면 월드오브워크래프트는 확장팩 대격변을 전후하여 레벨에 따른 스킬 콘텐츠를 재배치하여 새로운 시도를 선보였다. 그 반면에 테라는 화려한 그래픽을 강점으로 내세우지만 낮은 몰입도와 레벨에 따른 스킬 콘텐츠가 부족하고 그 의도마저 모호하다. 이러한 특징은 실제 테라를 플레이할 때 나타나는데 월드오브워크래프트에 비해 상대적으로 단조로운 스킬 선택권과 직업 선택권의 형태로 발견되어지는 문제로서 제안하는 방법이 몰입도를 측정하는 하나의 방법으로 평가된다.

The hardware-based software has been loaded in almost all industrial fields including the embedded system field. As it is increasingly important to control product quality, the more businesses are expending great quality cost. However, most domestic corporations in Korea are bent on spending more money solving problems caused by poor quality rather than prevention of quality loss cost. Therefore, it's time to improve to use quality prevention cost efficiently. As for this, there has been a growing interest in controlling quantitative quality, but the managing activities for quantitative quality require a high maturity process, belonging to Level 4 and 5. So it is necessary that statistical quality control activities should be fulfilled. This study introduces various measures to build up quality control among the process areas of TMMi Level 5 to help establish the high maturity test processes of statistical quality control.

The purpose of information system audit is to proactively identify and efficiently manage all risk factors that may arise during the process of constructing an information system, in order to assist in achieving the objectives of information system development. However, there is currently significant dissatisfaction with the quality and effectiveness of the auditing process, leading to ongoing research aimed at finding effective solutions. In this paper, we propose a multi-level evaluation model to enhance mutual understanding between auditors and evaluators and present a model that undergoes a maturity process, improving its levels and stages. We introduce a maturity-based evaluation model platform, enabling efficient communication between auditors and evaluators, allowing for real-time feedback, and supplementing it through continuous search. By presenting this multi-level model aimed at maturing the entire system, we aim to efficiently manage the system development process.

Technology readiness assessment is a procedure for managing defense project risk factors based on the preemptive identification of technical risks. Under current regulations, technology readiness is determined based on considerations of the ratings of factors itemized on a checklist, whether unsatisfied factors have a fatal impact on the project, and whether countermeasures for unsatisfied factors have been established. However, objective criteria for assessing the impact of unsatisfied factors have not been presented, and thus, at present, the results of technology readiness level determinations are largely subjective. In addition, the importance of questions on the checklist is dependent on individual project characteristics and this is not considered during the assessment process. In this paper, we propose an improved technology readiness assessment procedure that considers the characteristics of each project. Using the proposed procedure, we quantitatively determined the importance of each checklist item using a weighting method. We found the devised procedure improved the reliability and objectivity of technology readiness assessment results. A case analysis of a complex weapons system is presented to demonstrate these improvements.

CMMI는 조직의 역량 성숙도를 향상시키기 위한 소프트웨어 프로세스 개선(SPI) 모델이다 CMMI의 단계적 형태(Staged Representation)의 2레벨을 획득하기 위해서 요구되는 요구사항 관리 프로세스 영역은 요구사항에 대한 협의 확정(Commitment) 활동을 포항하고 있다. 요구사항 관리 프로세스 영역은 이전에 협의 확정된 요구사항이 필요한 경우 변경이 가능하도록 허용하고 있는데, CMMI와 같이 프로세스 중심적인 모델에서 이러한 변경 가능성은 협의 확정 사항의 무한정 확대(Escalation of Commitment)와 같은 문제점을 야기할 수 있다. 본 논문에서는 SPI학계에서 사용되는 협의 확정에 대한 정의를 살펴보고, 이 정의를 CMMI에 적용함으로써 요구사항 관리 프로세스 영역의 협의 확정을 수행하는 활동에서 발생할 수 있는 문제점을 해결하기 위한 방안을 제시한다. 협의 확정의 개념은 Brown에 의해서 정의된 속성(1)과 Meyer에 의해서 제안된 형태(2)를 적용하여 정성적이고 정량적인 관리가 가능할 수 있다. 이를 통하여, 요구사항의 협의 확정에 대한 체계적인 관리가 가능해질 수 있다.
