  • Risk assessment should be processed when physical circumstances of airspace such as establishment of new flight procedures or reconstruction of existing airspace are planned to change and one of the alternatives for the change have to be selected. This is an effort to find the best alternative which is able to maintain at or above the acceptable risk level. ICAO and its contracting states provide specialized guidance material for 'Safety Management System' relating to handing airspace matters. These manuals include a conceptual framework for managing safety as well as some of the systemic processes and criteria used to meet the objectives of a State's safety programme. This criteria must be established in compliance with the State's laws and regulations for air safety and for the fulfillment of the State's safety goals. This study is to carry out the risk assessment criteria through literature reviews relevant to the safety management, and to propose the results of criteria to be applicable for establishing flight procedure design process.

  • The knowledge of the behavior of any roller compacted concrete (RCC) dam and its foundation is gained by studying the service action of the dam and its foundation using measurements of an external and internal nature. The information by which a continuing assurance of structural safety of the RCC dam can be gauged is of primary importance. Similarly, the fact that the information on structural and thermal behavior and the properties of concrete that may be used to give added criteria for use in the design of future RCC dams is of secondary importance. Wide spread attention is now being given to the installation of more expensive instrumentation for studying the behavior of concrete dams and reservoirs and forecasting of any adverse trends. In view of this, the paper traces installation and need of the comprehensive instrumentation scheme implemented to monitor the structural and thermal behavior of 102.4 m high RCC dam constructed near Mumbai in India. An attempt is made in the present paper to emphasize the need to undertake an instrumentation program and evaluate their performance during construction and post construction stage of RCC structures. Few typical results, regarding the thermal and structural behavior of the dam, obtained through instrumentation installed at the dam site are presented and compared with the design considerations. The fair agreement is seen in the response observed through instrumentation with that governing the design criteria.

  • Purpose - The purpose of this study was to propose a specific and empirical continuous transaction strategy through service quality of improvement to small and medium Korean companies whose main business is B2B distribution and sale of general-purpose SW. Research design, data, and methodology - The research procedure is largely divided into two phases. In the first phase, the service quality, the customer satisfaction, and the continuous transaction research hypothesis and the verification are carried out. Experimental data were collected from 450 companies, CEO companies of SMEs innovation institutes, and 510 companies from medium and large enterprises. From September 15 to October 5, 2015, 215 questionnaires were used. And research hypothesis and test were conducted by SPSS SW Ver. 20. Results - The results of the study confirm that service quality has a positive effect on customer satisfaction and continuous transaction: as the detailed items for improving the service quality, 'responsiveness', 'assurance' and 'empathy' have been adopted. Therefore, there are critical factors of a company's survival through continuous transaction. Conclusions - Through this study, we confirmed that the survival of small businesses require continuous improvement in service quality. Among the factors improving service quality, empathy means service satisfaction of customers; so, it is necessary to continuously improve it by evaluating customer satisfaction. Responsiveness means rapid response to customer needs and reliability; it is necessary to enhance customer responsiveness by continuous job training and service training. Finally, assurance is the same as sales product or after service. This means that it is necessary to not only issue the "supply contract," but also improve the reliability of the sales product by securing the competence of the consulting professional. However, because the service quality measurement factors selected in this study are the measurement factors that are mainly applied to large companies or those in the service industries, it is important to consider the type of sales of software distribution companies.

  • 현재 국내 건설 산업은 고층화, 대형화 되어감에 따라 새로운 기술 개발로 비약적인 발전과 함께 품질향상을 위해 품질관리기법 및 품질관리제도 개선을 하고 있지만, 기술개발에 비해 건축물의 품질향상수준은 미흡한 수준이다. 반면에, 사용자의 의식변화로 건설품질에 대한 관심이 증가됨에 따라 요구품질수준이 높아지고 있다. 정부에서는 책임감리제도의 시행 및 해외업체의 국내 감리업무진출 허용 등의 품질제도를 강화하였고 및 민간부문에서도 사전자격심사제도의 시행 및 ISO 9000시리즈의 품질보증 등을 통한 품질 향상을 꾀하고 있지만, 현행 건설공사는 설계, 재료, 공법 등이 이미 확정된 발주자의 공사 시방서에 의한 공사를 수행함에 따라 정해진 사항의 이행 여부만을 판단할 뿐 수급자의 품질 개선을 위한 기술 개발의 필요성 및 기회를 제공하지 못하고 있다. 따라서 본 연구에서는 건설 공사단계에서 수급자가 자발적으로 품질확보를 할 수 있는 지불규정제도의 업무프로세스와 제도개선 방안을 제시하였다.

  • Background: Korean Hospital Standardization Program(KHSP), as a hospital accreditation program initiated and promoted by Korean Hospital Association since 1981, has played a key role in the hospital quality improvement in structural aspect particularly. Recently, however, KHSP has been critisized by hospitals and health personnels in that it is unpractical to be utilized as an initiative to improve hospital quality. In particular, the section of quality assurance in KHSP, strongly influenced by old version of Hospital Accreditation of Joint Commission in U.S.A., has been required to be fundamentally revised. For design of new criteria in quality assurance section, a survey for evaluation of existing program and collection of opinions for ideal one was conducted. Methods: For a month in 1994, structured questionnaires were administered by mailing to 470 hospital staffs from 200 hospitals, participated in the survey for the 1994 KHSP in each hospital. The total number of respondents was 116. Results: Less than half of the respondents(34.5%) value positively on the impact of current KHSP in general on the quality improvement of their hospitals. Moreover, most responses indicated that KHSP should be reorganized towards more practical and applicable one. Current KHSP criteria for quality activities in hospitals were regarded as a unpractical one which should be basically renewed. For new criteria and standards, most respondents emphasized the importance of applicability of those in real situations. Conclusion: For the KHSP to be effective, new evaluation criteria for quality activities should be more practical and fully accommodated to hospital situations in reality.

  • Achievement of objectives of education and training is one of significant factors influencing quality of life. Higher education institutions use different work, teaching methods and tools; however they are inadequate in many cases. Today higher education institutions have problems concerning sustention and rise of certain level of education by giving the job for graduates, using of new technologies that help to present, manage, evaluate and control knowledge. The main objectives of quality management system (QMS) at higher education institutions are as follow: to assure continuous improvement of education quality; to demonstrate performance results and relevant facts to the interested parties (customers of college or university, social partners, administrative institutions) showing the abilities of education institution to prepare high qualification specialists that fully correspond to changing requirements of labour market. The QMS at education institutions should be designed as continuous process, considering that the quality of final product is the result achieved in primary processes. The process shall involve all interested parties. Parameters and indicators of education quality can help to analyze the efficiency and effectiveness of existing QMS. The results of quality audits should be also taken into account when designing and implementing QMS at organization. Literature review showed that for the assurance of education quality three different approaches prevail: total quality management (TQM); requirements of quality awards and assessment models; and QMS corresponding to the requirements of ISO 9001 standard. The case study of QMS design and implementation at Vilnius Law and Business College is presented in the paper. The peculiarities, difficulties and obstacles of QMS implementation in the higher educations institutions are analysed in more detail in this article.

  • Quality Assurance of Deep Mixing to fulfill the requirements of geotechnical design cannot be achieved only by the process control During production conducted by the deep mixing contractor but it should involve relevant activities that are carried out prior to, during and after the construction by all the parties involved in a deep mixing project. The requirement is different for different application, and hence, QA/QC method/procedure and verification technique may be different for different application. In order to maintain the high quality of deep mixing work in the global market, it is necessary to conduct a research project, such as investigation of illustrations, the variety of existing QA/QC methods/procedures, the correlation between the outcomes of different QA/QC methods. In these reason, it has been held the international meeting to discuss them, in that kind of activities in 2009 it will be held Symposium. Also Collaborative study for QA/QC is on goin, and conduction by all participated members.

  • 본 연구에서는 횡등방성 특성을 갖는 인쇄회로기판(PCB)의 물성 예측을 위한 방법을 제안하였다. 등방성 소재와 달리 횡등방성 소재의 물성 취득을 위한 별도의 시험기준은 없으며, PCB와 같이 적층된 형태의 박판 구조물에 대해서는 재료시험 또한 쉽지가 않다. 모달시험을 통해 취득한 모달 파라미터와 상용 소프트웨어인 $OptiStruct^{(R)}$의 치수 최적화 기법을 활용, 시험-해석 간 주파수 차이를 최소화시키는 강성행렬 성분을 도출하여 기계적 물성을 예측하였다. 또한 주파수 별 모드형상을 MAC(Modal Assurance Criteria) 값을 기준으로 비교, 검토하여 예측 물성에 대한 유효성을 확인하였다. 제안된 방법은 향후 PCB를 포함하는 전장제품의 설계검증을 위한 구조해석에 확대 적용될 것으로 기대한다.
