  • The purposes of this study were: a) to develop the a quality measurement tool for the contract-managed hospital foodservice, and b) to evaluate their performance with the developed quality measurement tool, and c) to verify the reliability and validity of the quality measurement tool. The developed quality measurement tool comprised two parts, which were foodservice management and medical nutrition care service. The foodservice management part was classified into six functional categories which were Menu, Procurement and Storage, Production and Distribution, Facility and Utility, Sanitation and Safety, and Management and Evaluation. The medical nutrition care service part indicated the medical nutrition care provided. Quality measurement tool had 91 standards and 324 indicators. The quality measurement tools were distributed to the hospital foodservice manager employed by the foodservice company. The 324 indicators were measured by foodservice manager on the 5-Likert-type scales, and then adapted to a 100 point scale. The SPSS Ver. 11.0 was used for statistical analysis. The categories whose scores were evaluated as being high were Procurement', General Sanitation', Personal sanitation' and Waste' and the categories whose scores were evaluated as being low were Diet Order Manual', Standard Recipe', Appropriateness (Facility and Utility)', Check (Facility and Utility)'and Information Management'. All the categories of medical nutrition service were evaluated as having seriously low scores. Therefore, it was necessary for the contract-managed hospital foodservice to improve its performance in the area of medical nutrition care service. For the verification of the developed quality measurement tool, the reliability obtained by calculating Cronbach's α was 0.8747, and the content validity was also proved by scrutiny of the modification of the Professional group's techniques.

  • 본 연구는 중국 대리시의 근린공원인 얼허공원(洱河公園)을 대상으로 공원 내 환경요소들이 노인의 만족도에 미치는 영향 요인을 도출하고 만족도를 분석하여 개선 방안을 제안하고자 한다. 먼저 노인을 대상으로 한 공원 및 외부 공간의 환경 평가와 관련된 선행연구를 통해 평가 지표를 선정하였으며, 설문조사와 요인분석을 실시하여 영향 요인을 도출하였다. 다음으로 노인들의 만족도를 알아보기 위해 퍼지 종합 평가를 실시하였으며, 개선 방안을 제시하기 위한 중요도와 성취도분석(IPA) 을 수행하였다. 연구 결과를 살펴보면, 요인분석을 통해 공원 환경요소들을 시설적합성 및 쾌적성, 이용편의성 및 안전성, 자연쾌적성, 도로편의성 4가지로 유형화하였다. 이를 바탕으로 얼허공원 환경요소에 대한 전체 만족도 등급은 만족과 보통 사이로, 자연쾌적성의 등급은 만족이고 시설적합성 및 쾌적성, 이용편의성 및 안전성의 등급은 보통으로, 도로편의성의 등급은 만족에 가깝게 나타났다. IPA 분석 결과 중요도는 높지만 만족도가 낮아 중점 개선이 필요한 항목은 휴게시설의 적절성, 편익시설의 적절성, 시설의 관리 상태, 진입의 안전성, 조명시설로 분석되었다. 본 연구의 결과는 향후 노인 친화형 공원을 신설하거나 재정비할 때 활용 가능한 기초자료를 제공하여 만족도를 높이고자 하는데 의의가 있다.

  • 미끄럼방지포장은 도로의 부속물로서 도로 및 교통 특성으로 인해 미끄럼저항을 충분히 확보하지 못한 곳이나 도로선형의 변화가 심한 구간에서 포장의 미끄럼저항을 높여 자동차의 안전한 주행을 도모하기 위한 시설이라고 명시하고 있다. 특히, 눈, 비, 블랙아이스와 같은 기상 악천후 상황에서 미끄럼방지포장의 미끄럼저항성능은 도로교통 및 운전자의 안전에 큰 영향을 미친다. 하지만 현재 미끄럼저항성능을 측정하는 데 주로 사용되는 BPN은 시험 면적이 0.009 m2에 불과하여 전체 포장면에 대한 대표성을 나타내기 어렵기 때문에 미끄럼방지포장 유지관리를 위한 신뢰성 있는 미끄럼저항성능 평가방법이 필요한 실정이다. 본 연구에서는 지침 및 표준 조사를 통하여 BPN, SN, GN 시험의 미끄럼저항 성능평가 방법을 비교하고 현장 미끄럼저항 성능평가에 적용하고자 하였다. 또한, 미끄럼방지포장의 체계적인 유지관리를 위하여 미끄럼방지포장재 미끄럼저항 성능평가 Test-bed 및 실도로 실증 현장에 미끄럼저항성능이 다른 미끄럼방지포장을 설치하여 성능평가방법(BPN, SN, GN)별 미끄럼저항성능을 비교하였다. 실험결과, SN과 GN은 미끄럼저항성능이 비슷한 경향으로 나타났으며, GN은 BPN × 0.01 과 유사하게 도출되었다.

  • Risk-based estimation has been successfully introduced into the construction industry. By incorporating historical data associated with probability analysis, risk-based estimate is an effective decision support aid in considering whether to launch a particular project. The industry challenges, however, especially related with management issues, such as labor shortage, wage growth, and supply chain complexity, have often resulted in poor cost performance. The insufficient assessing the project characteristics (i.e., resource availability, project complexity, and project delivery method) can be the main reasons in the poor cost performance. Because the accuracy level of cost performance prediction can be enhanced by extensive evaluation of the subject project characteristics, a new approach for predicting cost performance in an earlier stage of a project can improve the Industry substantiality, in other words, value maximization. The purpose of this paper is to develop a new methodology in developing a risk-based estimate tool by incorporating extensive project characteristics. To do this, an extensive industry survey was conducted from both private and public sectors in building industry in Korea. In addition, significant project characteristics were identified in terms of cost performance indicator. Although the data collection is limited to Korean industry the suggested approach provides the industry with a straightforward methodology in risk management. As many researchers maintained that front-end planning efforts are crucial in achieving the successful outcome in building projects, the new method for risk-based estimation can Improve the cost performance as well as enhance the fulfillment in terms of business sustainability.

  • An open rack vaporizer is a facility that vaporizes liquefied natural gas using sea water. When a vaporization efficiency of the open rack vaporizer decreases, liquefied natural gas can leak, which can cause great damage to the facility. Operators have to monitor the operation state of the facility in real-time to prevent the accident. However, operators have visited the site and have checked the state by looking at the value of sensors installed in the open rack vaporizer through indicators. For the safe operation of the open rack vaporizer, a monitoring system is needed to monitor the operation state of the open rack vaporizer in real-time without the need for operators to visit the site. In this paper, we developed a long term evolution based monitoring system to monitor the operation state of the open rack vaporizer. The developed system can monitor the real-time operation state of the open rack vaporizer at a control center far from the facility. For the system development, data transmission infrastructure using long term evolution was built. Afterwards a software was developed to monitor the operation state of the open rack vaporizer in real-time using the transmitted data. Finally, performance evaluation was conducted to confirm that the developed system operated successfully without data transmission delay or data missing.

  • Since the basement building like the communication hole and etc. is built under the ground where it is pressed by the water, the leakage happens due to the dried-shrinking crack, the sinking crack, the creation of the work-joint of the building and etc. caused by the character of the material and construction way of the reinforced concrete building. Especially, a lot of repair for the leakage cannot help but being taken in temporary way without any noticeable countermeasure. Therefore, this kind of repair is socially criticized many times that this is defective construction even if this costs a lot. The fundamental reason of the above mentioned symptoms can be found in the creation of the work-joint caused by the character of the concrete building, the limitation of the physical performance of the existing water-proof and repair material, the limitation of the construction, the limitation of the physical sustaining performance of the concrete building, the limitation(heat-injury, deterioration) of the constancy of the durability caused by aging and etc. Therefore, in this study, we would like to present the better understanding on the water-proof seal relating to the application at the spot and its test evaluation related data since the necessity of the establishment of the quality control standard and the performance testing way on the relevant water-proof seal is rising a lot to regulate the water-proof technology and the leakage repair technology in accordance with the growth of the demand on the facility.
