  • It is essential to build a high quality database in developing a UIS to enhance the administrative effectiveness of municipal governments. To secure such a high quality DB, a proper methodology of quality control should be established. It is imperative to have such a method fit UIS DB considering that the conventional method has mainly been focusing on the quality control of the digital layers itself. Therefore, this study have analyzed the city of Inchon's UIS DB to devise a proper method to categorize the types of errors and to identify major relevant items. Also, the magnitude and frequency of each error along with its major cause have been analyzed to propose a quality control procedure to minimize the errors

  • In this study, we investigated methods of quality check for digital basemaps and proposed effective methods of quality check. We used new statistical methods for quality control in order to carry out quality check for digital basemaps. We proposed 2-stage complete sampling and 2-stage cluster sampling method to improve present statistical methods of quality check(1-stage complete sampling method). We estimated error rate and number of omitted objects using simulated data about all delivered digital basemaps and estimated variances about it. We could determine confidence interval about error rate and number of omitted objects.

  • This research, through an empirical analysis of the management of food materials in the super deluxe and deluxe hotels in Seoul, verified the difference, and established strategies according to the difference. According to the study, to enhance the level of the food material management, the introduction of scientific methods and system of the deluxe hotels has to be preceded, the training of special inspectors and the utilization of inspection methods needs improvement, and the purchasing contracts and effective purchasing methods have to be renewed. As for the storing management, the difference between hotel grades was low. The implication of this study as follows. First, to enhance the efficiency of man power operation, we have to introduce computer systems. Second, training based on the food materials purchasing manual has to be achieved. Third, we have to increase inspectors' specialty through the arrangement of man power rotation.

  • 국가 간 무역 활성화로 인하여, 국제 물류의 고도화가 요구되는 현 시점에서 보세창고의 운영 효율성을 제고할 필요성이 커지고 있다. 그러나 현재의 보세창고 프로세스 중 검수 및 장치화물관리 프로세스는 수작업으로 인한 오류발생률이 높아 효율성이 저하되는 문제점을 가지고 있다. 따라서 본 논문에서는 이에 대한 해결책으로 보세창고에 RFID 기술을 적용하여 검수작업을 자동화하는 방안을 제시하였다. RIFD 기술 도입은 검수 작업의 효율화뿐만 아니라, 향후 실시간 장치화물관리, 창고 내 Resource 관리 등 창고관리의 제 분야에 활용되어 보세창고관리의 효율성을 제고시킬 것으로 기대된다.

  • Many companies have struggled to manage Web vulnerabilities and security incidents have also frequently happened. The current inspection methods are mainly based on the OWASP vulnerabilities. In practice, however, it is very difficult to cope with frequent changes of Web applications. In this paper, we first investigate the existing quantification of Web application vulnerabilities and verification process. Then we propose an improved inspection framework which is focused on removing essential and realistic vulnerabilities and active verification process.

  • Many GIS systems are not to be trusted becuase many GIS project managers often fail to notice importance of GIS data Construction. With this reason, it is a lively discussion on GIS administration system's adaption. The definition of GIS administration system is not clear, but GIS administration system generally is devided information system administration, audit guideline for the data construction of GIS. Audit guideline for the data construction of GIS. GIS data construction's goals are logical and reasonable action policy of GIS data construction in widespread filed, the other goal is creation of product to the purpose exactly. Audit guideline for the data construction of GIS is composed of optimum of GIS data construction's planning, optimum of GIS data construction's activity, optimum of GIS data quality management, optimum of consultations of GIS data construction, GIS data audit. GIS data audit is the phase of detection product's potential error in each level. GIS data audit is composed of filed examination or filed verification, examination with the naked eye, screen verification, program verification, auto verification. GIS information system's efficiency is linked with auto verification system's function variety, accuracy. this paper offer introduction of Audit guideline for the data construction of GIS, efficient auto verification program

  • This study was conducted to investigate the perception of the management of food service in schools. The subjects consisted of 271 school dietitians in the Daegu and Gyeongbuk areas. The questionnaire included the food temperature management and the frequency of the food quality confirmation. The sanitation performance of the delivery workers was evaluated with a 5-point Likert scale. The food items for which the proper temperatures while they were being received were difficult to maintain were as follows: ready-to-use vegetables, 49.8%; frozen foods, 30.3%; and fish paste, 27.7%. The frequencies of the food quality confirmation whenever the foods were received were as follows: for beef, 87.5%; pork, 84.5%; chicken, 84.1%; eggs, 73.4%; seafood, 59.4%; and processed foods, 52.8%. The total mean score of the dietitian-perceived sanitation management performance of the delivery workers was 3.86/5.00. The school dietitians said the percentage of the mixed delivery of food items in vans was 80.4%. The percentage of the dietitians who thought this mixed delivery influenced food sanitation and quality was 92.3%. Therefore, safe foods should be supplied to schools with a thorough inspection process and hygiene education, and professional research is required on the appropriate inspection process.

  • SOFC 발전시스템의 상용화를 위해 선행되어야 할 것은 스택의 안정적 출력 및 신뢰성 확보이다. 이를 이루기 위해서는 스택을 구성하는 구성요소의 신뢰성 있는 규격 및 검수가 필요하다. 즉, 셀, 밀봉재, 분리판 및 집전체로 대변되는 구성요소들이 스택에 장착되었을 때 그 기능을 최대한 발휘하면서도 점진적 또는 급격한 품질저하가 발생되지 말아야 한다. 특히, 셀의 경우 스택의 성능에 직접적인 영향을 미치는 구성요소로서 품질에 대한 명확한 검수기준이 필요하다. SOFC용 셀은 다공성 anode, 치밀한 전해질, 그리고 다공성 cathode로 구성된 세라믹 소결체이다. 이 때 치밀한 전해질에 결함이 내재되어 있거나 물리적 힘에 의해 신규로 발생할 경우, 연료로 사용되는 수소와 공기가 만나는 cross-over가 발생하게 된다. Cross-over는 연료가 소모되는 문제도 있지만 발열로 인한 Hot spot을 형성시켜서 주변과의 온도구배를 유발하고, 이로 인해 고체 전해질의 균열전파를 일으킬 수 있고 나아가 급격한 셀의 파괴를 야기할 수 있다. 본 연구에서는 SOFC에 사용되는 셀의 형상측정, 물리적 강도 및 결함 검출을 위한 검수기법을 개발하여 스택의 신뢰성 향상과 향후 규격표준화를 위한 기반을 제공하고자, 평판형 셀의 3차원 형상을 정밀하게 측정하는 장치와 일정 면압을 인가하여 특정 형상을 갖고 있는 셀의 물리적 파괴여부를 판단할 수 있는 장치, 그리고 셀의 전해질에 내재된 결함을 검출할 수 있는 장치를 제작하였다. 본 장치들은 $1,000cm^2$급 평판형 셀까지 검수할 수 있도록 고안하여 양산시스템에 접목시킬 수 있도록 고안된 것이다. 본 장치들을 이용한 검수결과, 현재 $700cm^2$급 평판형 셀의 경우 최대 camber가 4mm 이하, 전해질의 He leak rate는 $5{\times}10^{-5}mbar.l/s.cm^2$ 이하라는 검수규격을 본 연구소에서 운전하는 스택에 1차적으로 적용하였으며 현재 검수규격의 신뢰성 및 강화를 위한 연구를 수행 중에 있다.
