The purpose of this study is to identify the problems of the distribution and maintenance of the KOLAS, and provide the developmental direction of the KOLAS. The research methods for this study are both survey and field interview. The results show that first, the National Library of Korea should continue to distribute the KOLAS to public libraries, and second, there are a lot of problems for maintenance of the KOLAS. However, some of the problems of KOLAS could be resolved, but not all of them. Thus, this study proposes the developmental plan of the KOLAS for future. The National Library of Korea should open the KOLAS to open source software for public, so that libraries and vendors may develop new ILS based upon the KOLAS.

The purpose of this study is to build outcomes evaluation system for measuring outcomes of programs provided by a public library. For the study, we constructed outcomes evaluation system(LibOutcomes system) that applied library outcome measurement framework based on the logic model and this system made librarians to measure outcome directly import data from the KOLAS and upload it. As a result, LibOutcomes system was useful for verifying outcomes as visual result. In addition, since the system was built a web-based system, it is possible to secure accessibility and ease of use. Finally, we suggested possibility to expand the system as a function of KOLAS in the future.

The purpose of this study is to analyze the characteristics of OPAC displays of three children's libraries in Korea: Seoul Children's Library, Cheongju Miracle Library, and Yongsan Public Library. 'OPAC Display Guidelines( Draft)' Published by IFLA is used to examine the details of OPAC displays, and to suggest their improvement. Discussed are such topics as the features of basic and detailed search screens, the brief display of search results, the arrangement and full display of bibliographic records, and the use of terms and labels. All three libraries offer their users the same KOLAS' OPAC, only designed to serve general users rather than children, i.e., their primary user group. They show some weakness, and much improvement is urgently required to satisfy specifically the needs and information seeking behavior of children.

K-water have been operating as an International accredited calibration organization for ISO 17025 regarding float, ultrasonic and radar type since 2008. Due to the absence of on-site calibration system, water level meter could only be calibrated from a laboratory. Therefore K-water institute developed an mobile calibration system for water-level meter in 2015 to calibrate the water-level meter on site. The mobile calibration system was certificated by KOLAS(Korea Laboratory Accreditation Scheme) in 2016. In this paper a mobile calibration system, which is a method to calibrate float type water level meter on site, is established. A mathematical equation was derived by reviewing characteristics of standard equipment and measurement. By developing the mobile calibration system, it is possible to achieve reliability of data through scientific system operation on hydrological data.

The purpose of this study is to determine how to apply ISO/IEC/IEEE 29119 software test procedures and ISO/IEC 25023 software test evaluation items to software-accredited testing laboratories based on the ISO/IEC 17025 international standard requirements. As a method, the overall requirements for their application to a test laboratory were analyzed by mapping ISO/IEC/IEEE 29119 and ISO/IEC 25023 based on ISO/IEC 17025. According to the mapping analysis, a total of 29 documents were created, including quality manuals, procedures, and test guidelines for the operation of the test laboratory. As a result of the study, a test laboratory management system was developed using Confluence 6.15 software by applying the analyzed results of the overall requirements. The test procedures, documents, and records were stored in, and operated from, this system. Verification of suitability for operation of the test laboratory was conducted by KOLAS evaluators through a document review and an on-site audit at the LG Electronics SW Accredited Test Laboratory in Seoul. In conclusion, it was confirmed through the KOLAS evaluation that the test laboratory management system and the operation of the test laboratory are appropriate and, compared with previous cases, the test laboratory operates effectively, and the overall schedule of accreditation could be shortened.

The requirements for medical laboratories ISO 15189 is examined in organization and a quality management system, stressing the importance of evidence, document control, and control of records and clinical material. Medical services are provided from the areas of resource management, and pre-examination, examination and post-examination processes. The main goal of ISO 15189 accreditation is to improve the quality of laboratory services provided for patients and clinical users not only through compliance with consensually developed and harmonized requirements but also by adopting the philosophy of continual improvement using the Plan-Do-Check-Act cycle. Laboratory quality should be evaluated and improved in all steps of the testing process as the state-of-the art indicates that the pre- and post-analytical phases are more vulnerable to errors than the intra-analytical phase. The Korea Laboratory Accreditation Scheme (KOLAS), a national accreditation body, provides medical laboratory accreditations for appropriate approaches to evaluating the competence of a medical laboratory in providing effective services to its customers and clinical users. Adoption of ISO 15189 in 2010s as a government policy has been delayed, and only 5 laboratories have been accredited to date in Korea. The medical laboratories should seek the adoption of ISO 15189 with a positive attitude for quality improvement and strengthening of international competitiveness.

The tipping-bucket and weight measuring type precipitation gauge has long been used worldwide for measuring rainfall. However, the conventional gauge has observation errors and its measurement range is limited by the device's resolution. In this paper, a new type of precipitation gauge that uses an innovative method by applying a new ultrasonic flow measuring technique was developed. This is the first time this technique is being used to gauge rainfall. The prototype was tested in the laboratory designated by the Korea Laboratory Accreditation Scheme (KOLAS). The rainfall intensity condition was 20~420 mm/H and the Standard Correction System for Precipitation Gauges was used. Results of the laboratory experiment showed that the proposed gauge has a ${\pm}2%$ margin of error. Consequently, it was proven that the proposed gauge is quite accurate and reliable for measuring precipitation.

This paper introduces the IN-FLEX system using aluminum clad flex cable, which is expected to alternate the conventional wiring method, such as, a steel pipe wiring method, and a synthetic resin pipe wiring method. The aluminum clad flex cable has a superior operation characteristics in heat dissipation property, in installation and maintenance facility, flammability, and appearance. Moreover, the IN-FLEX system adopted an easy connection mechanism which enable to reduce the time, hands and expense for the installation and maintenance of the system. Certification tests verifying the superior operation characteristics and reliability of the system using aluminum clad flex cable were carried with standard method in KOLAS certification institute.

This research aims to develop a voyage performance monitoring system based on international standards. The developed system is equipped with an electronic navigational chart(ENC) that provides onshore and offshore information, as well as supports standardized interfaces with navigational equipment, such as a gyro compass, a differential global positioning system(DGPS), and an automatic identification system(AIS), to monitor the navigation route in real time. In addition, the proposed system adopts a car navigation system to provide a graphical user interface, an intuitive menu-driven configuration, and an easy guide for safer sea navigation. The system, interfaced with the gyro compass and DGPS, was verified without any data loss, and passed a test conducted under extreme conditions by the Korea Laboratory Accreditation Scheme(KOLAS). Finally, the system contributes to preventing collision of vessels and minimizing casualties by maximizing the convenience of mariners which a conventional system does not provide.
