Environment has formed characters of one society and the society has formed its characteristic cultural behaviors. Oppositely cultural behaviors make the characteristic products like environment and space products. It gives the idea that we can create cultural space by examining cultural characteristics. This research bases on the 5 cultural dimensions of Geert Hofstede to inspect cultural quality of Korea and the 10 cultural factors of Edward. T. Hall in order not to omit some part of cultural characters. From April 2004, KTX which is originated from TGV of France began toroll in Korea. It is interesting that the same interior of train is used by two different cultures. The method to find out the special quality of transportation culture of Korea passed 5 steps like following; 1) making a questionnaire to understand general concepts 2) observation to make dear what are the special behaviors in the interior of train 3) comparison valuation with marking sheet of the interiors of KTX and HSR in order to find out which space Korean people prefer 4) comparison of behaviors in the interior of KTX and TGV 5) Interviewing and surveying the opinions of passengers of KTX. With these methods it would be possible to seek out the characters, preferencesand needs for the interior space of train. There were remarkable things like following 1) importance of privacy from the other's eyes 2) seriousness of individual seat because of the short term transportation 3) necessity of continuous information because of 'Uncertainty Avoidance Culture' 4) absence of moving 5) requirement of bright and comfortable interior like one's inner room 6) preference to take a seat as a group with their friends or family due to 'Collective Culture' 7) self-defense and self-protection of one's baggage because of 'Uncertainty Avoidance Culture'. With these discoveries this research suggests guidelines to design interior of train of Korea.

This study aims to obtain technical data for improvement of utilization of Blast Furnace Slag(BFS), recycled aggregate in the future by complementing fundamental problems of BFS such as manifestation of initial strength and excessive alkali quantity as well as weakness of recycled fine aggregate through manufacturing of recycled fine aggregate mortar using BFS. The recycled aggregate includes the cement paste hardened as the surface and the type of the aggregate, which contains plenty of calcium hydroxide($Ca(OH)_2$) as well as the unhydrated cement. Accordingly, the objectives of this study are to inspect the manufacturing the recycled fine aggregate mortar used with blast furnace slag, to consider the effects of the recycled aggregate on the strength development of ground granulated blast furnace slag, and then to acquire the technical data to take into consideration the further usages of the recycled aggregate and blast furnace slag. In eluted ions from recycled aggregate, it showed that there were natrium($Na^+$) and kalium($K^+$), expected to be flown out of unhydrated cement, as well as calcium hydroxide($Ca(OH)_2$). Application of this water to mix cement mortar with ground granulated blast furnace slag was observed to expedite hydration as calcium hydroxide($Ca(OH)_2$) and unhydrated cement component were expressed to give stimuli effects on ground granulated blast furnace slag. The results of the experiment show that the recycled aggregate mixed with blast furnace slag has comparatively higher hydration activity in 7 day than the mortar not mixed with one in 3 day mortar does, causing the calcium hydroxide in the recycled fine aggregate to work on as a stimulus to the hydration of ground granulated blast furnace slag.

National plant quarantine inspector of exporting country should inspect agricultural products according to the quarantine requisites of counterpart country when the commodities are shipped. Export of pear fruits was held because quarantine pests including Conogethes punctiferalis were found at the point of entry in Canada. In order to examine the problems in detail, the inspected pear fruits were stored at a low temperature for 43 days, almost the same period necessary for fruit sorting, quarantine procedures, and transportation by ship. Dead larvae of fruit moths, C. punctiferalis and Grapholita molesta were found during cold storage. Quarantine pathogens were not found, but non-quarantine ones such as Penicillium sp. was infected through wounds by bruises and stabs resulted from sorting procedures. Because of the wounding problem during export procedures, pear fruits with thin exocarp, such as fruits of P. pyrifolia Nakai cv. Whangkeumbae, are required more careful handling during fruit sorting and conveyance.

This study suggested the problems and their improvement measures for the operation of fire detectors and sprinkler heads installed at apartment houses. According to a census on population and housing in 2010, apartment houses account for 71.6% of the total housing facilities. And by fire statistics data of the National Emergency Management Agency, approximately 25.0% of fire accidents and 46.4% of casualties occur at apartment houses every year. Therefore, this study conducted for identifying the causes and characteristics of fire to establish the fire safety improvement measures for apartment houses. And this study was carried out virtual fire simulation at domestic apartment houses. The scenario of the simulation contains a comparative analysis on the operation time of standard sprinkler heads and residential sprinkler heads, heat detectors and smoke detectors. As a result of simulation, it was found that standard sprinkler heads and heat detectors installed at the existing apartment houses should be replaced with residential sprinkler heads and smoke detectors for rapid fire suppression. In addition, sprinkler systems should be considered to be installed for excluded floor at apartment houses. Especially, it is necessary to construct remote inspect systems like advanced countries for efficiency of apartment houses safety management.

Retail is called location business because it is one of the most important factors to estimate management of stores for retailers who are going to sell products directly to customers. Retailers' management achievements are shown in sale in general. Therefore, retailers tend to focus on ways to increase the numbers of customers in order to raise sales. First of all, in this research, I am going to examine the most fundamental models such as Reilly's retail gravitation, converse model, huff probability model and multiful losit model in selecting stores. Secondly, I am going to provide the process and analyzing ways to predict estimated sales amount with the previous theory model. Also I am going to predict estimated sales amount of the department store L which is located in D metorpolitan city. Lastly, I am going to argue about the problem of this research and the next research subject. Our main goal is to provide ways to complement and inspect sales estimation models, which can be used in fields after taking characters of high class structure of Korea into consideration on the base of previous researches. According to the result of the research, my conclusion is that if the process of analysis and changing factors are complemented, revise model, which can reflect reality of Korea, will be provided. Therefore, in the future study, we have to build up theory models to suit for our retail market through critic reviews about the existing high class structure of Korea.

Recently, security behavior of members of organizations has been recognized as a critical part of information security at the corporate level. Leakage of customers' information brings more attention to information security behavior of organizations and the importance of a task force. Research on information breach and information security is actively conducted of personal behavior toward security threats or members of organizations who use security technology. This study aims to identify factors of influence on information security behavior of members of organizations and to empirically find out how these factors affect information security behavior through behavior toward attitude, subjective norm and perceived behavior control. On the basis of the research, this study will present effective and efficient ways to foster information security activities of members of organizations. To this end, the study presented a research model that applied significant variables based on integration of Theory of Planned Behavior (TPB) and Theory of Protection Motivation (TPM). To empirically verify this research model, the study conducted a survey of members of organizations who had security-related work experience at companies. So, it is critical for members of organizations to encourage positive word of mouth (WOM) about information security behavior. Results show that based on the integration of TPM and TPB, perceived vulnerability, perceived severity, perceived efficiency and perceived barriers of information security behavior of members of organizations had significant influences on mediating variables such as behavior toward attitude, subjective norm, perceived behavior control and intention. They also had significant influences on organization information security behavior which is a dependent variable. This study indicates companies should introduce various security solutions so that members of the organizations can prevent and respond to potential internal and external security risks. In addition, they will have to take actions to inspect vulnerability of information system and to meet security requirements such as security patches.

In order to efficiently inspect rapidly increasing old tunnels in many well-developed countries, many inspection methodologies have been proposed using imaging equipment and image processing. However, most of the existing methodologies evaluated their performance on a clean concrete surface with a limited area where other objects do not exist. Therefore, this paper proposes a 6-step framework for tunnel crack detection deep learning model development. The proposed method is mainly based on negative sample (non-crack object) training and Cascade Mask R-CNN. The proposed framework consists of six steps: searching for cracks in images captured from real tunnels, labeling cracks in pixel level, training a deep learning model, collecting non-crack objects, retraining the deep learning model with the collected non-crack objects, and constructing final training dataset. To implement the proposed framework, Cascade Mask R-CNN, an instance segmentation model, was trained with 1561 general crack images and 206 non-crack images. In order to examine the applicability of the trained model to the real-world tunnel crack detection, field testing is conducted on tunnel spans with a length of about 200m where electric wires and lights are prevalent. In the experimental result, the trained model showed 99% precision and 92% recall, which shows the excellent field applicability of the proposed framework.

To improve fuel performance and specific characteristics of long storage and moving through fuel systems additives should be added in kerosene type aviation turbine fuel (AVTUR) such as antioxidant, fuel system icing inhibitor (FSII), electric conductivity improvers and so on. The dosage of additives has to be analyzed qualitatively and quantitatively due to inspect the quality of abnormal fuel and distinguish other petroleum products. Multi-dimensional GC-MS (MDGC-MS) with Deans switching technique are applied the determination of antioxidant and FSII, which are added with AVTUR containing complex mixture of hydrocarbons. Antioxidant and FSII in the range of 2.5-20 mg/L was quantitatively and qualitatively analyzed using MDGC-MS and the detection limit was about twice as low as that of the 1-dimensional GC-MS results. The method in this study has been higher peak resolution compared with GC-MS and could be simultaneously analyzed different two additives without sample pre-treatment.
