Dissolved silica is one of fatal components at a boiler facility Therefore, a dissolved silica measurement system should be equipped for managing efficiently the boiler facility. Most of silica measurement systems are composed of a sensor module of single-beam type structure, and silica density is measured with a infrared spectrometry using the Lambert-beer method. However, such a system occurs measuring error of large range and inconsistency of a light source, because of measuring a standard sample and a measuring sample alternatively. This paper introduces a method that the sensor module has a split-beam type structure and a tungsten lamp. The proposed system can measure silica density quickly and precisely more than those composing of a single-beam type structure, because of measuring and comparing with two samples at a same time. And examination results are shown to compare efficiencies of the system and existing commercial products, and for an ammonia influence.

The construction of an underground silo structure was the first stage of erecting the Gyeongju low-and-intermediate-level radioactive waste disposal facility. The facility, completed in 2014, has a scale of 100 000 drums and is currently in operation. The underground silo structure, 25 and 50 m in diameter and height, respectively, consists of cylindrical (for storing waste packages) and dome parts. The dome is divided into lower (connected to the operation tunnel) and upper parts. The wall of the underground silo structure is an approximately 1-m-thick reinforced concrete liner. In this study, finite element analysis was performed for each phase of the construction sequence and operation of the underground silo structure. Two-dimensional axial symmetric finite element analysis was implemented using the SMAP-3D program. Three-dimensional finite element analysis was also performed to examine the reliability of the two-dimensional axial symmetric finite element model. The structural behavior of the underground silo structure was predicted, and its structural safety was examined.

This article examines the effects of education service quality of culinary education facility on the learning outcome. For this, items for figuring out the relation between education service quality and the learning outcomes has been deducted through IPA regarding education service quality. Further, the factors of education service, which is for verifying the effects of relevant experiences (culinary certificate) have been examined according to advanced studies. Self administered questionnaires have been prepared by 231 samples in total and the collected data have been analyzed through frequency, factor, reliability and regression analyzing methods by using SPSS 18.0. The results from paired t-test performed on the importance and performance of culinary education service quality indicate that expertise, level of knowledge, education method of instructor and additional convenience facilities (locker and lounge etc) are the most important factors respectively. The results from IPA analysis show that the quadrant 1 includes knowledge level, education method, kindness of instructor. The quadrant 2 contains awareness of instructor while the third one includes culinary facility, tool structure and convenience facility. In addition the quadrant 4 includes hygiene of learning place. According to the results from hypothesis test, education service quality affects learning outcome and the experience (certificate) of learner from culinary education facility results in difference in education service quality and awareness of learning outcome therefore the hypothesis is partially verified.

It is not feasible for agricultural facility managers to estimate how severe damages are and what are causes of them when agricultural hydraulic facilities get damaged for some reasons. Moreover, it is nearly impossible for agricultural facility managers to take immediate actions to repair and reinforce the damaged structures. Thus, there have been needs for well-established systems to help agricultural facility managers understand its severity and causes, and take proper actions to reduce speed of deterioration and to repair/reinforce them. Thus repairing and reinforcing systems of agricultural hydraulic structures based on agricultural facility management policies, developed in this study, can be efficiently used in field works to determine top priority location and the budget of repairing and reinforcing projects if detailed information of damages in concrete structures and damage types are well compiled and classified with standardized image data complemented.
