정보화의 진전으로 행정 및 공공기관이 보유한 데이터에 대한 활용요구가 증대하고 있으나, 데이터 품질 문제로 많은 행정 및 공공기관이 공공 데이터의 개방 공유에 적극적으로 참여하고 있지 못하다. 본 연구에서는 선행연구에서 제시된 데이터 품질관리 성공요인을 조직적 차원과 관리적 차원으로 구분하고 이들 요인이 조직의 데이터 품질관리 수용을 통해 품질수준에 영향을 미치는지를 분석하였다. 연구결과, 품질관리 권장 및 지원과 같은 조직차원의 요인은 품질관리 수용에 영향을 미치며, 기관의 데이터 품질 수준과 관계를 가지는 것으로 나타났으나, 법제도 및 책임소재의 명확화와 같은 관리적 차원의 요인은 품질관리 수용에 영향을 미치지 않는 것으로 나타났다. 본 연구는 공공기관을 대상으로 한 품질관리가 초창기인 현 상황을 고려할 때 관리적 접근보다 전사차원의 공감대 형성이 필요함을 제시하였을 뿐만 아니라, 품질 수준에 직접적으로 영향을 미치는 품질수용 요인을 도출하여 제시하였다는데 의의를 가진다.

Purpose: This study aims to examine such relationships as the experiential value that customers respond to with regard to maintenance service by empirically revealing how the quality of auto maintenance and repair service affects both customer satisfaction and intention to reuse the same service through the Perceived-experiential Value of customers. Research design, data and methodology: The research model was designed with service qualities such as human quality, material quality, interaction quality, and system quality as independent variables, perceived-experiential value as a parameter, and service satisfaction and return visit intention as dependent variables. Through a questionnaire composed of 24 items, a total of 319 survey data from customers with the experience of using car maintenance service centers in Korea were collected and analyzed using a structural equation. Results: The material quality did not affect the customers' perceived-experiential value, whereas the interaction quality had the greatest influence. It is confirmed that human quality, interaction quality, and system quality can generate customer satisfaction and repurchase intention through the perceived-experiential value. Conclusions: The experiential value of customers can play an important medium role in improving satisfaction, with customers considering interaction quality important. Therefore, the auto maintenance and repair service should consider relationship-focused service strategies.

The purpose of this study was to measure the effects of value and satisfaction moderating the relationship between foodservice quality and behavioral intention. A total of 273 questionnaires were completed. Moderated regression analysis was used to measure the relationships between variables. Results of the study demonstrated that the analysis result for the data also indicated excellent model fit. The main effects of foodservice quality, value, and satisfaction on behavioral intention were statistically significant. The interaction effect of quality and satisfaction on behavioral intention was not statistically significant. The interaction effect of value and satisfaction on behavioral intention was not statistically significant. As expected, the interaction effect of quality and value on behavioral intention was statistically significant. Moreover, foodservice quality on behavioral intention was statistically significant at all levels of value and satisfaction, except for when value level was low, and satisfaction level was high. The results of this study indicated that restaurant marketers should attach importance to the interaction effect of service quality and customer value to understand the elements of market demand and customer loyalty.

수질지수는 여러 수질 데이터 값을 수학적으로 결합하고 다 변수 특성을 줄여 수치 및 등급으로 나타낸 지표이다. 수질지수를 통해 수질을 평가하고 서로 다른 위치와 시간의 수역을 종합적으로 비교할 수 있으며 수자원관리에 있어 정책입안자, 의사결정자, 국민이 수질에 대해 일반적이고 쉽게 이해할 수 있다. 현재 환경부에서는 국내수질자동측정망 최근 12시간 데이터 값을 근거로 실시간수질지수 RTWQI(Real-Time Water Quality)값을 제공한다. 국내 호소에 설치된 수질 자동측정망은 총 8개소이며 매 시간 공통 항목인 수온, pH, DO, 전기전도도, TOC 5개, 선택항목인 탁도, Chl-a, TN, TP, 중금속, 생물감시항목 등 27개를 측정한다. RTWQI는 캐나다에서 2001년에 개발된 CCME WQI(Canadian Council of Ministers of the Environment Water Quality Index) 산출식을 기초하였으며 F1(기준치를 위반하는 수질항목의 개수/ 총 수질항목 개수), F2(기준치를 위반한 샘플들의 총 횟수/총 샘플횟수) F3(기준치를 위반한 정도) 3가지의 요소로 계산된다. 그러나RTWQI 산출식의 기초인 CCME WQI는 개발 이후 여러 문제점들은 개선되었으나 F1이 다른 F2, F3 보다 CCME WQI 점수의 기여도가 2배 이상 높은 문제점은 개선하지 못하였다. 본 연구에서는 수질자동측정망이 설치된 2012년 7월부터 2021년 12월 동안 매 시간 별 수질 데이터를 이용하였다. 또한 CCME WQI 문제점을 개선한 MWQI(Modification of Canadian water qaulity index)를 기초하여 실시간 수질지수를 재 산정하였다. 추가적으로 Pearson 상관관계 분석 및 추가 통계분석을 통해 환경부에서 제공하는 기존의 RTWQI, 개선된 실시간수질지수, 한국형 호소수질평가지수 LQI(Lake Water Quality Index)를 비교 및 평가하였다. 이러한 연구를 통해 정확성 높은 수질지수를 찾고 수자원 관리 정책 수립에 적극 활용 될 수 있을 것으로 사료된다.

This study is an analysis of distribution of patients who installed Xive implant in Yonsei University Hospital and types of implant site for about 2 years recall check and cumulative survival rate. 41 implant were used in this study. It shows the conclusion below. 1. Patients at the age of 40s and 50s were 60% of all implant cases and average number of implant was 2.4(man), and 1.9(woman). All cases were operated on mandible, 3 implants on anterior region and 38 implants on posterior region. 2. The major cause of tooth loss is dental caries(48.8%), followed by periodontal disease. 3. Most distribution of bone qaulity for mandibular implant site was type II(65.8%) and bone quantity was type B(75.6%). 4. The majority of implants were those of 11, 13mm in length(95%) and regular diameter in width (64%). 5. The 41(19 persons) Xive implants that were placed in the mandibular anterior and posterior region were all survival and showed a 100% 2 year cumulative survival rate. The results provided us with basic data on patient type, implant distribution, bone condition, and survival rate. We wish that our results coupled with other research data helps assist in the further study for better implant success rates, etc.

This study is an analysis of distribution of patients who installed Implantium implant in Yonsei University Dental Hospital and types of implant site for about 1 years recall check and success rate. 164 implants were installed to 52 patients in this study. It shows the conclusion below. 1. Patients at the age of 40s and 50s were 65% of all implant cases and average number of implant was 4 (man), and 2.7 (woman). 75 implants were operated on maxilla and 89 were mandible. 19 implants on anterior region and 145 implants on posterior region. 2. Most distribution of bone qaulity for implant site was type III(37.2%) and bone quantity was type C(61. 7%) 3. The majority of implants were those of 10, 12mm in length (85%) and regular diameter in width (48.8%). 4. 30 implants were installed with the advanced technique-GER, window opemng, osteotome technique. 5. Two implants were removed before prosthodontic treatment due to the osseointegraton failure. The success rate was 98.8% in 15.2 months follow up period and the marginal bone loss was 0.28mm. The results provided us with basic data on patient type, implant distribution, bone condition, and survival rate. Within the limit of present study, It was concluded that Implantium implant could be used satisfactorily in various clinical situations.
