The purpose of this study is to evaluate chemical properties, textural characteristics and sensory properties which produces the mokwapyun from the tapioca starch. The mokwapyun-added tapioca starches hold higher moisture contents than mung bean starches. And, the ratios of tapioca starch indicate differences in the study (p<.001). The pH increases with the increasing amounts of tapioca starch and acidity measurement decreases as amount of tapioca starch increases. The 0% addition of tapioca starch is the highest for lightness and 20% addition of tapioca starch is the lowest. Both the redness and yellowness are being increased with increases in the addition of tapioca starch. According to the results of texture, 0% addition of tapioca starch is the highest for hardness, springiness and chewiness of mokwapyun which increases with additional percentages of tapioca starch. Nevertheless, it decreases the cohesiveness and brittleness due to increases in the percentage of tapioca starch. According to the result of DSC analysis, the more tapioca starch added to the mokwapyun, the higher the To, Tp, Tc temperatures become. The result of this study shows that the right contents of tapioca starch with 15% additions make positive acceptability, prepared sensory and machinery characteristics.

In this study Muffins adding each 0, 1, 3, 5 7% of Acai Berry powder, which has very high anti-oxidant constituent, have been made, and its quality characteristics have been surveyed. From the volume and specific volume measurement, it has been decreased for MA1, 1% of Acai Berry powder added muffin, but the tendency thereafter has shown increasing (p<0.001). From texture characteristics gumminess and chewiness of MA0, reference group, was the highest by 885.86 g/ cm and 6645.71 g, and has shown decreasing tendency as per the adding rate of Acai Berry powder increased (0.001). The electronics scavenging activity of MA7, 7% added muffin, was the highest by 68.91%, and the ascending order was MA1 < Reference Group < MA3 < MA5 < MA7. From the preference test of Acai Berry powder added muffin, MA3, 3% added muffin, was the most preferable one from color, taste as well as total preference. As the added volume of Acai Berry powder is 5% or more, the typical taste and flavor of Acai Berry gives influence to the taste and flavor of muffin, so the preference level has been decreased. Thus the added volume of Acai Berry powder 5% or more is not recommendable.

Purpose: This study was conducted to investigate the physical and sensory properties of seasoned powders utilizing tomato. Methods: Tests of salted tomato powder were performed for the physiochemical properties (moisture content, pH value, titratable acidity, color value, salinity content, and solubility content), sensory characteristics and sensory preference. Results: Moisture content of salted tomato powder containing fully ripened tomato (RT) was higher than that of salted tomato powder containing cherry tomato (CT), with the exception of CT 10%. The pH values of RT was relatively high and increased salt addition increased the pH as well. The titratable acidity was opposite the result of pH measurement. The color values of RT was higher than that of CT for the L, a, and b values. The salt content of RT was higher than that of CT. RT 10% showed the highest dissolution followed by CT 10%. In addition, the sensory preference for CT 10% was the highest, with the best scores for appearance and taste. Conclusion: It was concluded that 10% salt addition is the most suitable sensually for the manufacture of salted tomato powder.

In recent years, building commissioning has often been part of a standard delivery practice in construction, particularly in the high-performance green building market, to ensure the building is designed and constructed per owner's requirements. Commissioning, therefore, intends to provide quality assurance that buildings perform as intended by the design and often helps achieve energy savings. Commissioning, however, is not as widely adopted as its potential benefits are perceived. Owners are still skeptical of the cost-effectiveness claims by energy management and commissioning professionals. One of the issues in the current commissioning practice is that not every project is guaranteed to benefit from the commissioning services. This, coupled with its added cost, the commissioning service is not acquired with great acceptance and confidence by building owners. To overcome this issue, this paper presents a unique methodology to enhance owner's predicting capability of the degree of success of commissioning service using the Bayesian theorem. The paper analyzes a situation where a future building owner wants to use a pre-commissioning in an attempt to refine the success rate of the future commissioned building performance. The author proposes the Bayesian theorem based framework to improve the current commissioning practice where building owners are not given accurate information how much successful their projects are going to be in terms of energy savings from the commissioning service. What should be provided to the building owners who consider their buildings to be commissioned is that they need some indicators how likely their projects benefit from the commissioning process. Based on this, the owners can make better informed decisions whether or not they acquire a commissioning service.

실시간 시험자료 토픽은 시험을 수행하는 네트워크에 연결되어 있는 여러 계측 장비로부터 실시간으로 데이터를 수신하여 분석 처리하고 계측장비로 데이터를 제공하거나 가시화 할 수 있는 일종의 패킷 형태를 의미한다. 기존 UDP 통신프로토콜을 활용한 구조에서는 모든 계측장비들이 전송하는 데이터를 하나의 패킷으로 통합 설계하여 계측장비들의 필요유무와 상관없이 송 수신 하는 한계점이 존재하였다. 하지만 DDS(Data Distribution Service)를 활용하여 제안하는 시스템의 토픽 설계는 다음과 같은 장점들이 있다. 각 시스템에서 사용하는 플랫폼에 유연하게 공통된 API를 사용하여 개발이 가능하며 향후 장비 업그레이드 시 필요 토픽의 추가 선언 등 최소 작업만 필요하고 전체 시스템을 재설계하지 않아도 된다. 또한 시스템 간 연계를 위한 계측장비 및 시스템이 추가로 도입 시에도 공통 메시지 포맷을 적용하여 개발하기 때문에 기존 장비의 수정이 불필요하여 시스템의 확장이 용이하다. 추가 장비의 도입은 토픽의 QoS(Quality of Service) 튜닝을 통하여 우선 적용할 수 있기 때문에 통신의 성능을 조정 및 유지할 수 있다. 본 논문에서는 이종 시스템간의 플랫폼과 통신 프로토콜을 통합 설계한 DDS 미들웨어를 활용하여 새로운 센서 및 계측장비 도입 시 기존 시스템 구성장비들의 수정과 시스템의 별도 통신 커넥션, 신규 장비의 도입 및 업그레이드에 따른 시스템 S/W 재설계를 지양하는 토픽의 설계를 통해 보다 효율적인 자료 전달체계를 제안하고자 한다.
