The SSE-CMM model is how to verify the level of information protection as a process-centric information security products, systems and services to develop the ability to assess the organization's development. The CMM is a model for software developers the ability to assess the development of the entire organization, improving the model's maturity level measuring. However, this method of security engineering process improvement and the ability to asses s the individual rather than organizational level to evaluate the ability of the processes are stopped. In this research project based on their existing research information from the technical point of view is to define the maturity level of protection. How to diagnose an information security vulnerabilities, technical security system, verification, and implementation of technical security shall consist of diagnostic status. The proposed methodology, the scope of the work place and the current state of information systems at the level of vulnerability, status, information protection are implemented to assess the level of satisfaction and function. It is possible that measures to improve information security evaluation based on established reference model as a basis for improving information security by utilizing leverage.

Production processes of double wall bellows can be roughly categorized into two steps. In the first step, inner and outer bellows are made of STS316L in austenite stainless steel due to their excellent formability and corrosion resistance. In the second step, the double wall bellows are manufactured using the welding method with both the inner and outer bellows. The microstructure and defects of each weldment are observed to ensure the reliability of bellows since weldment is a highly vulnerable part, which can crack and fracture when bellows are formed or used. In this study, optimum welding conditions were derived from the analysis of microstructure and inspection of weldment of bellows that were produced using various welding procedure. Moreover, the mechanical properties were evaluated through hardness measurement of substrate, weldment and the heat-affected zone.

Many organizations have had deep interests in studies concerning leadership and also in academic area, not only management but also psychology. Until now, the leadership has been accentuated to managers or team leaders especially. Recently, however, the concept of self-leadership that lead one's own activities toward right direction through self-control or self-management is being focused on practices and academia. This study is to investigate the influence between self-leadership strategies and learning performance at IT classes mediated by attitude of attendance focused on the social science students in an university. Research results can give us right direction of task-taking attitudes in firms or learning attitudes in teaching organization and implications to human resource manager who are in charge of improving learning performance or productivity.

The object of this paper is established for a paradigm for the organization. Although concerns on management get increased in these days, there is no general and systematic framework for a unified sector. Therefore this study proposes the new general and systematic framework for managing in organization, through applying Service-Engineering model. The new framework of this study provides the general sector of organization model, the method of analyzing BSC and RMS, and system model for Risk Management. Furthermore, this study suggests the practical ways of developing a paradigm.

The microstructure and mechanical properties of unidirectionally solidified Al-Fe-Ni and Al-Fe-B alloys have been studied in varying the some conditions. To investigate the change of microstructure and mechanical properties was carried out by the varying the composition and solidification rate from 1.2 to 80 mm/min at temperature gradient 60 .deg. C/cm. The results obtained are as follow; 1. In proportion to the increase of the solidification rate, the type of crystallized phase of these composite alloys was changed by added element. a) The crystallized phase of composite alloy in added nikel was changed from the rod-type fiber to platetype fiber. b) The crystallized phase of composite alloy in added boron was changed from the plate-type fiber to rod-type fiber. 2. The strength was rapidly increased with the changing process of crystallized fiber from the plate-type fiber to the rod-type.

The standard and code of safety for diving systems include requirements in the area of diving plant, personnel qualification, diving medicine and operation. In this study the necessity of Korean standard and code of safety for diving system is suggested through the review and comparison of the diving system regulations of domestic as well as foreign governments and other private organizations. Furthermore, by reviewing the status of oversea's diving organizations the proposition was made which can lead the commercial diving sector to international cooperation.

A turbulent premixed flames of layer formed between burned hot gas and unburned mixture were investigated by means of schlieren photograph with fluctuations of temperature and ion current. The combustion intensity between burned hot gas and shear layer was higher than the intensity between unburned mixture and shear layer. A wrinkled laminar flame and flamelet were appeared at downstream to exist and distributed reaction zone was at upstream as a result of analyzed probability density functions of temperature fluctuation. The initial combustion intensity of reaction zone of eddy between burned hot gas and shear layer was higher than that of final, flowing downstream, and vice versa between unburned mixture and shear layer.

The demands for continuous process optimization require a radical rethinking of how information systems are designed and constructed. Information systems must be capable of sustained, graceful change in response to evolving business requirements. This proposition is supported by the fact that information systems have helped increase productivity only when they were built to support new and better ways of conducting the business. In such context, business process engineering (BPF) is recognized the first but most critical stage in developing information systems as well as in launching business improvement and innovation projects. However, more often, there exist great gaps and inconsistencies between the results of BPE and the business itself, which turn into huge maintenance overhead during an information system lifecycle. In order to solve such an ever lasting problem, this paper orthogonal models, procedure, guide, and work flow are constructed in our engineering discussions focus on decentralized organizations, the method is general enough to be applied easily to other types of organizations without difficulties.

제2차 석유위기 이후 국내외에서의 에너지의 효율적인 이용을 위해 보급된 COGN시스템은 앞으로 개발을 더해야 할 과제가 남아 있음에도 불구하고 계속 증설되고 있는데 이러한 추세는 앞으로 더욱 가속화 될 것이다. 본고에서는 COGN시스템에 대해 전반적으로 다루려고 하였으나 지면관계상 국내외의 현황과 과제 및 전력계통과의 연계부분에 대해 중점적으로 다루었다. 그러나 이러한 COGN시스템의 급격한 보급에도 불구하고 해외와는 달리 국내외에서는 이에 대한 현황자료의 정리와 과제 및 운용전략 등 차후의 방향 정립에 대해 매우 미진한 실정에 있다. 따라서 전력회사, 엔지니어링 회사, 산업용 및 민새용 COGN시스템의 관련 전문가들이 가칭 [COGN시스템 연구개발위원회]를 조직하여 순차적으로 기술적, 환경적, 운용적 및 정책적인 과제 등 앞으로의 문제들을 구체적으로 심도있게 다루어야 할 것으로 사료되며, 이를 통하여 우리나라에 COGN시스템의 더 많은 보급과 효율적인 에너지 사용이 이루어질 것으로 기대된다.

점차적으로 다양해져 가는 고객의 요구에 따라, 전자산업에 민감한 영향을 받는 엔지니어링 플라스틱 생산체제도 점차 다품종 소량 생산체제로 전화하고 있다. 이에 따라 기업의 내부조직에 있어서 생산성을 우선적으로 고려하는 생산부문과 납기를 우선적으로 고려하는 영업부문과의 생산스케쥴링에 관한 협의 업무가 전체 생산성을 저하시키는 요인으로 작용하고 있다. 본 시스템은 생산스케쥴링을 자동적으로 작성함으로써 영업부문에 스케쥴링 능력을 부여함으로써 생산스케쥴업무를 단일화하여 양 부문간의 협의업무를 간소화하고 생산부문에서는 생산에만 전력할 수 있도록 하여 전체 생산성을 향상시키는 데 그 목적이 있다. 본 시스템의 개발에 있어서 전문가 시스템 개발 tool로는 ART-IM을 사용하였고, GUI는 OSF/Motif로 구현하였다.
