As the need for the integration of administrative datasets and address information increases, there is also growing interest in POI (Point of Interest) data as a source of location information across applications and platforms. The purpose of this study is to develop an alias database management method for efficient POI searching, based on POI data representing position. First, we determine the attributes of POI alias data as it is used variously by individual users. When classifying aliases of POIs, we excluded POIs in which the typo and names are all in English alphabet. The attributes of POI aliases are classified into four categories, and each category is reclassified into three classes according to the strength of the attributes. We then define the quality of POI aliases classified in this study through experiments. Based on the four attributes of POI defined in this study, we developed a method of managing one POI alias through and integrated method composed of word embedding and a similarity measurement. Experimental results of the proposed POI alias management method show that it is possible to utilize the algorithm developed in this study if there are small numbers of aliases in each POI with appropriate POI attributes defined in this study.

Many researches have been done to develop and improve the performance of personal (individual) dosimeter response to cover a wide of neutron energy range (from thermal to fast). Depending on the individual category of the dosimeter, the semiconductor sensor has been used to simplify and lightweight. In this plan, it's very important to have a fairly accurate counting of doses rate in different energies. With a general design and single-sensor simulations, all optimal thicknesses have been extracted. The performance of the simulation scheme has been compared with the commercial and laboratory samples in the world. Due to the deviation of all dosimeters with a flat energy response, in this paper, has been used an idea of one semi-conductor sensor to have the flat energy-response in the entire neutron energy range. Finally, by analyzing of the sensors data as arrays for the first time, we have reached a nearly flat and acceptable energy-response. Also a comparison has been made between Lucite-PMMA ($H_5C_5O_2$) and polyethylene-PE ($CH_2$) as a radiator and $B_4C$ has been studied as absorbent. Moreover, in this paper, the effect of gamma dose in the dosimeter has been investigated and shown around the standard has not been exceeded.

The risk of multi-unit nuclear power plants (NPPs) at a site has received considerable critical attention recently. However, current probabilistic safety assessment (PSA) procedures and computer code do not support multi-unit PSA because the traditional PSA structure is mostly used for the quantification of single-unit NPP risk. In this study, the main purpose is to develop a multi-unit Level 2 PSA method and apply it to full-power operating six-unit OPR1000. Multi-unit Level 2 PSA method consists of three steps: (1) development of single-unit Level 2 PSA; (2) extracting the mapping data from plant damage state to source term category; and (3) combining multi-unit Level 1 PSA results and mapping fractions. By applying developed multi-unit Level 2 PSA method into six-unit OPR1000, site containment failure probabilities in case of loss of ultimate heat sink, loss of off-site power, tsunami, and seismic event were quantified.

The purpose of this study is to suggest public roles and responsibilities about Architecture Heritage under Act on Value Enhancement of Hanok and Other Architecture Asset by analyzing the Architecture Heritage System of Spain. The case study on Spain, Catalonia, Barcelona's Act of architectural heritage was conducted to analyze the laws and guidelines related to Architectural Heritage and to confirm the perspective on Architectural Heritage and roles by subjects through interviews with the department in charge. The role of the central governments is to the responsibility of preservation that can be offset by create incentives and expand programs to create consensus among citizens. The architecture asset survey, which is the responsibility of the municipal governments, should increase confidence by the detailed survey to define the authority and role of the basic local government. And the municipal governments must increase the architectural heritage more support and incentive. Excellence architectural assets must diversify the range of incentive and preservation, and ask for registration that various subjects can apply it by expanding category of application to public sector, non-governmental organization, citizens rather than an owner.

The prediction of spall response of reinforced concrete members like columns and slabs have been attempted by earlier researchers with analytical solutions, as well as with empirical models developed from data generated from physical or numerical experiments, with different degrees of success. In this article, compared to the empirical models, more versatile and accurate models are developed based on model-free approach of artificial neural network (ANN). Synthetic data extracted from the results of numerical experiments from literature have been utilized for the purpose of training and testing of the ANN models. For two concrete members, namely, slabs and columns, different sets of ANN models were developed, each of which proved to have definite advantages over the corresponding empirical model reported in literature. In case of slabs, for all three categories of spall, the ANN model results were superior to the empirical models as evaluated by the various performance metrics, such as correlation, root mean square error, mean absolute error, maximum overestimation and maximum underestimation. The ANN models for each category of column spall could handle three variables together: namely, depth, spacing of longitudinal and transverse reinforcement, as contrasted to the empirical models that handled one variable at a time, and at the same time yielded comparable performance. The application of the ANN models for spall prediction of concrete slabs and columns developed in this study has been discussed along with their limitations.

Objectives: This study identified changes in social communication and interaction among children with autism spectrum disorder (ASD) through Theraplay. Methods: This study included 20 children who were diagnosed with ASD by a child and adolescent psychiatrist and were recommended to undergo Theraplay in 2012-2017. The Marschak interaction method was used to identify and analyze the interactions between parents and their children. The Korean version of the Social Communication Questionnaire (K-SCQ) was used to evaluate symptoms of ASD. The Wilcoxon signed-rank test was used to compare the differences before and after Theraplay. Results: Upon comparing the differences in total K-SCQ scores, there were statistically significant changes (z=-3.269, p=0.001) in children with ASD. Changes were also confirmed in each category, namely social interaction, communication, and limited and repetitive behavior patterns (p=0.011, p=0.025, p=0.039, respectively). Conclusion: This study found that Theraplay may cause significant changes in social communication in children with ASD. Further studies are needed to establish the effectiveness of Theraplay in children with ASD.

In this paper, we describe a rule-based risk classification algorithm to perform Risk-based Inspection (RBI) on imported goods at customs. The RBI system is a method to automatically select which cargos have to be inspected and manage potential risks in boarder. In this study, we designed a rule-based risk classification algorithm for RBI solutions and implemented them using the Svelte web application framework. The risk classification algorithm proposed in this paper uses different indicative risk factors such as HS code, country of origin, importer's reliability, trade relationships, and logistics routes to classify cargos into Green, Yellow, and Red channels. To achieve this, we assigned risk categories to each risk factor and randomly generated risk scores within a specific range for each risk category. This system is expected to contribute to the increased efficiency of customs operations and protect public safety by minimizing the risk of imported hazardous materials.

Although ugliness had long been considered a negative form of beauty, it has become an independent aesthetic category. However, most previous art studies have focused on Rosenkranz's theory, making its application to contemporary fashion analysis challenging. Therefore, it is necessary to redefine ugliness. This study highlighted four modern ugliness categories from a modern perspective following the examination of the historical considerations of the ugliness concept, namely ugliness as a violation of taboo, ugliness as an unpleasant emotion, ugliness as a vulgar taste, and ugliness as an ethical flaw. From this perspective, SHOWstudios for fashion films were analyzed in the present study. The results of our analysis showed that ugliness in the film was related to socially sensitive subjects and stimulating images. Whereas costumes in the film were used as a tool to convey the subject and to enhance the visual effect of the image. In addition, clothing was identified as a core subject element of the video, particularly when considering ugliness as an ethical defect. This study provides further insights into contemporary fashion analysis, expanding the ugliness perspective, which had been limited to the specific perspectives of scholars.
