This research focuses on accomplishing analysis problems and issues by examining the policies and systems related to geo-spatial big data which have recently arisen, and suggests political and systemic improvement plan for service activation. To do this, problems and probable issues concerning geo-spatial big data service activation should be analyzed through the examination of precedent studies, policies and planning, pilot projects, the current legislative situation regarding geo-spatial big data, both domestic and abroad. Therefore, eight political and systematical improvement plan proposals are suggested for geo-spatial big data service activation: legislative-related issues regarding geo-spatial big data, establishing an exclusive organization in charge of geospatial big data, setting up systems for cooperative governance, establishing subsequent systems, preparing non-identifying standards for personal information, providing measures for activating civil information, data standardization on geo-spatial big data analysis, developing analysis techniques for geo-spatial big data, etc. Consistent governmental problem-solving approaches should be required to make these suggestions effectively proceed.

Even though Joseon Dynasty strictly identified between military and civil officials, the dress and its ornament have been studied only based on embroidery emblems that are correctly identified between military and civil officials. Thus, this study intends to research the features of the only military officials uniform, Cheollik, different from the civil officials's identifying them with other features shown from the records, unearthed relics, stone statue, Joseon-tongsinsa-haengnyeoldo(Illustration of Joseon Delegation to Japan), etc., and its results are as follows: First, for wearing examples of the military officials, from the facts that they had worn mainly ordinary clothes, etc. on announcement of military service examination. There was no difference between military and civil officials's clothes by Daejeonhusokrok and the other documents, and there was an assertion that the form of the military and civil officials's clothes should be different by the document, Hongjejeonseo, in the latter term of the Joseon Dynasty. It is presumed that length, width and shape of sleeves might have been different. Second, unearthed Cheollik of the military officials are mostly from the 16th~17th centuries and most of them have removable sleeves according to statistics. The skirt had an opening and one or two slits. Various textiles were used. Third, military official statues of high governor wear small caps and helmets. They wear Cheollik with the collars same as the collar of Bangryeong and Jikryeong, which is also called Dopji Cheollik. It would be considered as they wear the Bangryeong on top of the Cheollik. Fourth, militarly officials described on the Joseon-tongsinsa-haengnyeoldo(Illustration of Joseon Delegation to Japan) wear Cheollik, Rip, Donggae, Okro, Hongsadae, Hwando, Deungchae.

The current public survey performance review extracts samples according to the set screening ratio, and examines the extracted samples to determine the suitability or inadequacy of the survey performance. The examiner directly judges the survey performance submitted by the performer, and extracts it in consideration of various field conditions and topography for each subject. However, it is necessary to secure fairness in the examination as it is extracted with different extraction methods for each subject and the judgment of the examiner. Accordingly, in order to automate sampling for public survey performance review, the detailed sampling criteria of the reviewer were investigated to prepare a volume calculation table, and the automation of sampling using Python was studied. In addition, by reviewing items that can and cannot be automated, the application of the automated decision tree algorithm of sampling was reviewed.

Since comprehensive examination of flexible pavement is complex, evaluation of its condition has been based on subjective judgements. Especially, qualitative measure of pavement has been based on linguistic expressions which often cause misinterpretation. There has been no such a criterion that can appropiately assess pavement status. Therefore, this study was devised to develop an approach, using fuzzy set concept, for evaluation of current and expected service conditions of flexibel pavement surface course. An example study was conducted to verify its usefulness. Since arithematic operation of fuzzy set can quantify the linguistic values and translate them into illustrative models, the results shown in the example was easy for anyone to understand.

A long-term structural health monitoring (SHM) system comprising over 700 sensors of sixteen types has been implemented on the Guangzhou Television and Sightseeing Tower (GTST) of 610 m high for real-time monitoring of the structure at both construction and service stages. As part of this sophisticated SHM system, 48 temperature sensors have been deployed at 12 cross-sections of the reinforced concrete inner structure of the GTST to provide on-line monitoring via a wireless data transmission system. In this paper, the differential temperature profiles in the reinforced concrete inner structure of the GTST, which are mainly caused by solar radiation, are recognized from the monitoring data with the purpose of understanding the temperature-induced structural internal forces and deformations. After a careful examination of the pre-classified temperature measurement data obtained under sunny days and non-sunny days, common characteristic of the daily temperature variation is observed from the data acquired in sunny days. Making use of 60-day temperature measurement data obtained in sunny days, statistical patterns of the daily rising temperature and daily descending temperature are synthesized, and temperature distribution models of the reinforced concrete inner structure of the GTST are formulated using linear regression analysis. The developed monitoring-based temperature distribution models will serve as a reliable input for numerical prediction of the temperature-induced deformations and provide a robust basis to facilitate the design and construction of similar structures in consideration of thermal effects.

The vulnerability of concrete to its environment is significantly dependent on the fact that concrete is a porous material. For well-consolidated and well-cured concrete, its service life is a very long and an entrance of aggressive substance might be only pores. However, for cracked concrete, cracks should be preferential channel for the penetration of aggressive substance such as chloride ions. The effect of crack on chloride penetration depends on its size for example, crack width and crack depth. The purpose of this study is examining the effect of crack width and crack depth on chloride penetration. In order to visualize chloride penetration via cracks, RCM (rapid chloride migration) testing is accomplished. Crack width is examined using an optical microscope and CMOD value is used to estimate average crack width. From the examination on the trend of chloride diffusion coefficients of concrete specimens with various crack widths, a critical crack width and a critical crack depth are found out.

This study aims to analyze Sungkyunkwan Students' uniform during Chosen dynasty through literature and paintings. Confucian scholar's coshime of Chosen dynasty was said to imitate that of Chinese counterpart's. The first Confucian scholars costume, which was officially instituded during King Taeiong's reign, was a Yugon worn on the head and a Chongkeum (blue collar). But Chinese Gukjagam students'uniform in the early Ming years was a Nansam and later became a blue Wonryong which reflected the changes in the Ming Period. Though Chosun's Chongkeum was the official Confucian scholar's costume on record, it was not worn widely. Corfucian scholars rather wore a red Jikryong or a white coat up to the mid-Chosun dynasty, and in the late Chosen period, a black Danryong or a red Danryong were more popular for Confucian scholars. Because the official Confucian scholar's uniform Chongkeum was not used widely and other costumes were worn more popularly, various attempts had been made to adopt the Nansam, like that of Ming's, as the official Costume scholar's uniform from King Snio to King Youngio. Finally, King Youngjo decided to adopt the Nansam as the official costume for those who passed the civil service examination, ending the controversies concerning an official costume. We cannot find the Nansam and the Aengsam of the late Chosen period from the paintings either. This conirms that Aengsam was the costume which originated from the late Chosun period. The term "Chongkeum" was used either to imply "Confucian scholar' or to indicate various 'Confucian scholar's costume rather than its original meaning of blue collar.
