EMP(Electromagnetic Pulse) protection facility was evaluated according to standard of shielding effectiveness. To comply with the standard, transmitting antenna was placed on outside of protection facility and receiving antenna was placed on inside of protection facility. However, measurement is impossible that place does not have enough space between protection facility and external concrete structure. In this paper, we performed a various of tests that put transmitting antenna inside the EMP protection facility in order to find out test method for measuring the shielding effectiveness of electromagnetic wave. Transmitting antenna was placed on inside of the EMP protection facility for measuring the shielding effectiveness to compare and analyze the impact of the position regarding to the transmitting and receiving antenna. As a result of test, in case that transmitting antenna was placed on inside of the EMP protection facility, it was found that test frequency range 10 kHz~1 GHz were occurred overall average difference of ${\pm}4$ dB level.

Fuel assembly's mechanical characterization test facility (FAMeCT) in KAERI was constructed with upgraded functional features such as increased loading capacity, underwater vibration testing and severe earthquake simulation for extended fuel design guideline. This facility is designed and developed to provide out-pile fuel data for accident analysis model and fuel licensing. Functional tests of FAMeCT were performed to confirm functionality, structural integrity, and validity of newly-built fuel assembly mechanical test facility. Test program includes signal check of data acquisition system, load delivering capacity using real-sized fuel assemblies and a standard loading cylindrical rigid specimen. Fuel assembly's lateral bending test was carried out up to 30 mm of pull-out displacement. Limit case axial compression loading test up to 33 kN was performed to check structural integrity of UCPS (Upper Core Plate Simulator) support frame. Test results show that all test equipment and measurement system have acceptable range of alignment, signal to noise ratio, load carrying capacity limit without loss of integrity. This paper introduces newly constructed fuel assembly's mechanical test facility and summarizes results of functional test for the mechanical test equipment and data acquisition system.

This study is researched to provide design guidelines of service facilities and programs that apartment residents want along with the increased quality of life. This study is signifiant because it sought effective methods to activate the com-munity culture through service facilities in apartment complexes and the design standard and planning direction for residents. The study results are as follows. In the result of the correlations analysis and multiple regression analysis for the importancy of service facilities in apartment complexes, the following orders were considered as important factor; man-ager office, open space, resident community facility, elderly people meeting and activity facility, walking paths, resident athletic facility, a children's playground, library, and rest areas in the complex. and result of the correlations analysis and multiple regression analysis is the following: service facilities whole importance (y) = 1.413$+0.262^*{\times}1$ (manager office importance)$+0.271^*{\times}2$ (open space importance) $+0.185^*{\times}3$ (resident community facility importance) $+0.136{\times}4$ (elderly people meeting and activity facility importance)$+0.036^*{\times}5$ (walking paths importance) $+0.031^*{\times}6$ (resident athletic facility importance) + $(-0.042)^*{\times}7$ (a children's playground importance) + $(-0.045)^*{\times}8$ (library importance) + $(-0.0097)^*{\times}9$ (rest areas importance).

Play areas of childcare facility capable of stimulating the interests of children is extremely important. However, Childcare facility play areas in Korea are often placed in 'leftover' spaces due to institutional inadequacies. As a result, unlike the diverse play areas found in other countries, play areas in Korea have a standard appearance. Therefore, this study aimed to examine the specific causes of the physical differences in the childcare facility play areas of Korea and other countries. This study compared regulations, handbooks and guidelines and examined case studies of childcare facility play areas outside of Korea. Five institutional-level differences related to play areas between countries were identified as a result of this analysis. Suggestions for improvement at the institutional-level were proposed to each of the identified categories. This study focuses on the play areas of childcare facility and suggests directions for the improvement of play areas that are both institutionally and physically realistic.

With increasing interest in an underground-type ammunition storage facility, several design results have been provided recently. However, since not only experts in the tunnel but also military persons in charge of ammunition have not fully understood the safety distance standard, reliable design results are not being produced. In this study, the effective design method of an underground-type ammunition storage facility was provided by analyzing the current safety distance standard. First, the critical safety distances that dominate the size of construction site for underground-type ammunition storage facilities were evaluated, which are the layout of chambers and the configuration of the entrances. Then, the decreasing effect of inter-chamber distance was studied according to the rock type and the storage density of ammunition. In addition, the method of designing tunnels with parallel lines and two-floors was considered for arranging more chambers while complying with the safety distance standards. In particular, numerical simulations were carried out to determine the satisfaction of the safety distance standards when an underground-type ammunition storage facility is composed of two-floor and the decreasing effect of inter-chamber distance according to the inner explosive pressure reduction. Finally, the method to adjust the size of entrances and the path of pressure were studied for decreasing the safety distance at the entrance.

There are main issues of defect type that condensation, concrete crack and noise in apartment buildings. Especially, according to the Apartment Defect Dispute Mediation Committee in Korea (ADDMC) at Ministry of Land Infrastructure and Transport in Korea (MLIT), condensation defects are great importance (14 percent) on whole number of reported cases of faults from 2015 in Korea. Most condensation defects have many different causes that take a toll on the resident's life and space. So it is very important to early detection and repair. For preventing the condensation in apartment buildings, there are building codes in Korea such as 'Standard of Method and Judgment for Apartment defect of investigation, Repair cost Estimate'. This research aims to study on the improvement of preventing the condensation aforementioned korea standard. Types and characteristics (opaque wall, windows, doors) of cause of occurrence and existing state condensation defect is analyzed from evaluation of real application 100 case in 2015 ADDMC data.

Place names of road sign mean various place names being used on road signs for path guidance of drivers such as administrative district, facility, road, etc. It is very important that not only the choice method of place names for connectivity of road signs but standard establishment of spatial impact zone according to place names. However this standard are not established currently, so it is difficult to fix the spatial range for changing place names around the main facility according to the new construction or relocation of main facility in urban region. Considering the use of big data, one of the Government 3.0, we need to utilize actively the road sign management system database. This paper suggested a methodology for standard establishment of spatial impact zone according to place names of road sign in urban regions based on the road sign management system database. To perform a case study, we selected a major facility ("City Hall") which is the most frequently used the place name of road signs and presented standard of spatial impact zone by urban size in 84 cities.
