This paper intends to predict characteristic of the balcony space composition in apartment that residents want by analyzing floorplans utilizing balcony that is directly described by housewives in competitions. According to change of age, Modern's lifestyle is variously changed and future housing life may undergo changes continuously. Therefore, development of apartment housing plans is reflected by grasping and collecting space residents desire. Purpose of study is 1) arrangement characteristic of balcony space housewives prefer 2) relations characteristic between balcony and room adjoining balcony 3) characteristic of balcony space composition Through this study, the public space that family use together prefer facing the front side and the kitchen is required to face the front side. Balcony adjoining bedroom is utilized according to user of the bedroom, and independent space like hobby room do not have distinctive relationships with adjacent space. Recent trend that space is reflected in various lifestyle of resident require needs that exercise room for well-being life and other room for various functions. Based upon the study, the results show the basic information and understanding how the plans are supposed to change, particularly to facilitate the usage of the balcony.

In the field of clinical medicine, diagnostic accuracy studies refer to the degree of agreement between the index test and the reference standard for the discriminatory ability to identify a target disorder of interest in a patient. The receiver operating characteristic (ROC) curve offers a graphical display the trade-off between sensitivity and specificity at each cutoff for a diagnostic test and is useful in assigning the best cutoff for clinical use. In this end, the ROC curve analysis is a useful tool for estimating and comparing the accuracy of competing diagnostic tests. This paper reviews briefly the measures of diagnostic accuracy such as sensitivity, specificity, and area under the ROC curve (AUC) that is a summary measure for diagnostic accuracy across the spectrum of test results. In addition, the methods of creating an ROC curve in single diagnostic test with five-category discrete scale for disease classification from healthy individuals, meaningful interpretation of the AUC, and the applications of ROC methodology in clinical medicine to determine the optimal cutoff values have been discussed using a hypothetical example as an illustration.

This paper introduces a novel concept of the pulsed neutron facility (PNF) for maximizing the production of the thermal neutrons and its application to medical use based on prompt gamma neutron activation analysis (PGNAA) using Monte Carlo simulations. The PNF consists of a compact D-T neutron generator, a graphite pile, and a detection system using Cadmium telluride (CdTe) detector arrays. The configuration of fuel pins in the graphite monolith and the design and materials for the moderating layer were studied to optimize the thermal neutron yields. Biological samples - normal and cancerous breast tissues - including chlorine, a trace element, were used to investigate the sensitivity of the characteristic γ-rays by neutron-trace material interactions and the detector responses of multiple particles. Around 90 % of neutrons emitted from a deuterium-tritium (D-T) neutron generator thermalized as they passed through the graphite stockpile. The thermal neutrons captured the chlorines in the samples, then the characteristic γ-rays with specific energy levels of 6.12, 7.80 and 8.58 MeV were emitted. Since the concentration of chlorine in the cancerous tissue is twice that in the normal tissue, the count ratio of the characteristic g-rays of the cancerous tissue over the normal tissue is approximately 2.

The purpose of this study is to present the form of Korean policeman's headgear which is endowed with traditional Korean characters and a creative property that has distinctive from other headgears. The investigation was carried out through the researh of policeman's headgears in foreign countries such as United Kingdom France Belgium Italy germany and Japan. The dom-estic investigation was carried out through the Focused Group Interview and analysis on the domestic policeman's service and headgear. Lastly the research into the characteristic of Korean traditional headgear's from was carried out. Consequently two types of policeman's head-gear hat and cap were newly developed and the system of practical use was suggested. The results of this study were as follows: 1. Through the use of traditional and formal elements of Korean ancient headgears korean policeman's headgears were improved in distinc-tion and dignity. 2. Through the use of unisexual form police-man's headgears were improved in uniformity. 3. Through the use of transformal accessories policeman's headgear were improved in simplified system. 4. Through the use of newly formed and lighten weighted materials policeman's head-gears were improved in functionability.

In this paper, a conceptual approach of the stress path method was newly proposed for a rational estimation of settlements of saturated clay deposits. In the proposed approach, settlement-related characteristic deformation behaviors of a specific clay deposit, which can cover all probable stress changes expected in the field, are experimentally evaluated in advance. Then settlements of various structures constructed on the deposit are easily estimated with only the characteristic deformation behaviors and without any additional experimental effort. In Part I of this paper, in order to provide practicality to the new conceptual approach, we developed a detailed procedure which is capable of evaluating characteristic deformation behaviors of a saturated clay deposit with only a limited number of tests and easily predicting deformations under a given stress change using the characteristic deformation behaviors. The applicability of the developed procedure was clearly shown by presenting an actual application example.

In recent times, with the development of virtual convergence technologies, the market for the Metaverse, a digitally virtual space that combines virtuality and reality, is experiencing significant growth. These Metaverses are realizing new value in both reality and virtual spaces through the development of diverse services and content. However, existing research on the Metaverse mostly revolves around its conceptualization and categorization, with limited exploration of intentions to use the Metaverse. Consequently, this study examined the impact of Metaverse service characteristic factors on trust and intention to use within the Metaverse. The results of this study are as follows. First, among the service characteristic factors of the Metaverse, presence, interactivity, and playfulness were found to have a positive impact on Metaverse trust. On the other hand, informativeness was found not to have a significant influence on trust in the Metaverse. Second, Metaverse trust was found to have a positive impact on intention to use the Metaverse. Based on the research results above, this study aims to propose effective communication strategies for activating the Metaverse and developing services within the Metaverse platform.

The purpose of this study was to use the Korea Health Panel to determine how the mother's characteristic and household characteristic variables were associated with dental clinic use of children in childhood and adolescence. The logistic regression analysis found that mother's education level was statistically significantly positively correlated with underage child's dental clinic use and children in single-parent family were less likely to use a dental clinic than those in two-parent family. As for dental clinic use by diseases, the higher level of mother's education, the more likely to use a dental clinic due to dental caries and children in single-parent family were less likely to use a dental clinic due to dental caries than those in two-parent family. No difference in dental clinic use due to tooth extraction was found by any of mother's characteristics or household characteristics, probably because age has an absolute impact during the period between milk teeth and permanent teeth. Lastly, mother's education level and household income were significantly positively correlated with dental clinic use due to orthodontics. On the basis of these results, it is necessary to develop a customized strategy reflecting children's growth stages and household characteristics in making a plan for promoting oral health of children and adolescents.
