Recently, indoor air quality (IAQ) has been one of the major concerns of people. Indoor parking lots are subject to be exposed to high concentrations of air pollutants emitted from vehicles. This study was performed to investigate indoor air quality (IAQ) at indoor parking lots. Sampling sites were selected 5 indoor parking lots. Target indoor air quality parameters include a number of criteria pollutants such PM$_{10}$, CO, CO$_2$, and HCHO. In addition, a variation of IAQ according to ventilation system operating was measured at C site (underground parking lot). In general, all pollutants were maintained below indoor air quality maintenance standards. The indoor air quality at indoor parking lots was affected by the availability of the ventilation facility and their operation frequency. At the underground parking lot (C site) with ventilation system, TVOC concentration according to ventilation system operating were found to be lower operating (488.2 ${\mu}g/m^3$) than non-operating (1,401.2 ${\mu}g/m^3$).

정보화의 효과는 투자와 구축뿐만 아니라 정보시스템의 운영 수준에 따라 다를 수 있다. 본 연구는 국내 중소 제조기업의 정보시스템 운영 환경과 품질 수준을 조사 분석하고, 기업의 성과 지표에 어떤 영향을 미치는지 알아보고자 한다. 정보시스템 운영환경 요인이 정보시스템 품질수준을 매개로 생산성 성과와 재무성과에 미치는 영향을 구조 모형을 통해 분석하였다. 분석 결과로, 정보시스템 운영환경 요인들의 수준이 높을수록 품질수준은 높아지고, 품질수준이 높을수록 생산성 성과는 높아지며, 생산성 성과가 높을수록 재무성과는 높아진다고 할 수 있다. 정보화의 효과는 정보시스템 구축 후 운영 환경과 품질 수준에 달려 있다고 판단된다.

The purpose of this study was to investigate how the operating system quality of Cheongwon Organic Festival, a local festival held in Cheongju, affects visitor satisfaction, and to also revitalize the Cheongwon Organic Life Festival through this study. 344 visitors of the Cheongwon Organic Life Festival were recruited to become participants of this study using a random sampling method. There were significant differences in the evaluation of the operating system quality at the Cheongwon Organic Life Festival depending on the visitors' gender, age, education, household income, acquisition of information, purpose of visit, considerations of the purchase of festival goods, purchase of a pre-sales ticket, and residence.Different factors such as the visitors' gender, age, education, household income, acquisition of information, purpose of visit, considerations while purchasing festival goods, and residence impacted the visitors' satisfaction of their visit to the Cheongwon Organic Life Festival. It was found that there was a correlation between the operating system quality at Cheongwon Organic Life Festival and the visitors' satisfaction. The operating system quality as a whole and the event programming showed the highest correlation with the visitors' satisfaction.

Study on the performance characteristics of the solar hybrid system with heat pump operating temperature during winter season has performed by using an experimental test. The system performance and operating characteristics with the heat pump operating temperature, hour and load condition were investigated and analyzed. As a result, the hot water temperature was significantly affected by the heat pump operating temperature at the morning(time 1) and noon(time 2). However, hot water temperature was set by the radiation quality and collecting operation hour at the afternoon(time 3). In addition to the solar fraction was decreased for the high heat pump operating temperature because the heat pump operated with a long operating time and short operating period.

본 논문은 SDR(Software-Defined Radio) 송수신기의 운용 소프트웨어 품질평가를 위한 평가 척도를 제시하고 평가를 자동화할 수 있는 평가 소프트웨어 개발에 대해 설명한다. SDR 운용 소프트웨어는 하드웨어에 종속적인 동작을 하기 때문에 이에 맞는 평가 척도를 도출하기 위하여 동작 환경 및 운영 분야와 동작 방식에 근거한 품질평가 요구사항을 추출하였다. 도출된 평가 척도를 이용한 품질평가의 자동화를 위하여 평가 소프트웨어를 C#언어와 MySQL 데이터베이스를 이용하여 개발하였다. 평가 소프트웨어는 데이터베이스를 이용하여 평가 요소를 입력 또는 갱신할 수 있으며 스크립트를 이용한 자동 평가 기능이 있으며 평가 결과의 시각적 표현이 가능하도록 개발되었다. 도출된 평가 척도와 평가 소프트웨어를 사용하여 파악된 소프트웨어 품질 향상을 위한 개선점은 고품질 SDR 운용 소프트웨어 개발에 유용하게 사용되고 있다.

Objectives: The purpose of this study is to provide comprehensive information of qualification systems of developed countries needed to establish our national system for QI(Quality improvement) specialists. Methods: All articles related to any applicable domestic or foreign countries' laws, operational status, and detailed programs for professional qualification system of QI were reviewed. Result: In the United States, a non-profit organization, Healthcare Quality Certification Commission (HQCC) has set the policies, procedures and standards in the field of health care quality. And qualification system of CPHQ (certified professional in healthcare quality) has been operated in order to authenticate the qualifications in the field of quality management. IBQH(international Board for quality in healthcare), a qualification system of experts in the United Kingdom, was designed to assist the qualification of professionals to improve the quality of healthcare. In addition, Health Research Center of Feinberg School of Medicine in Northwestern University has been operating Master's and doctoral degree programs in the field of the quality of care and patient safety and IHI (institute for healthcare improvement) open school was operating a professional training course related to the quality of care and patient safety. Conclusion: Quantity and complexity of information of the quality of care and patient safety have been increased. For reform of the health care system, a special training course of the expertise and leadership are needed. So far, there is no national professional certification courses in our nation. Therefore essential job skill should be acquired individually. For systematic and effective quality improvement activities, the educational and certification system with professional development model are needed.
