This study examined one of the hypotheses on the consonant reduction in Korean inferred from the Articulatory Phonology framework through phonetic experiments: Degree of consonant reduction depends on the height of the neighboring vowels--the lower the height of the neighboring vowel is, the higher the degree of reduction of stop closure period is. The results of this study, in general, turned out to support the hypothesis with some cases requiring other phonetic considerations, e.g., rate of some tongue tip movement in the case of dental lenis stop /t/ or the facts that bilabial lenis stop /p/ share its primary articulators, lips, with the neighboring vowel /u/ and that for bilabial closure, the upper lip lowers more for compensation of little movement of lower lip when its raising gets disturbed for some reasons.

In this paper we propose a resource management method which enables to guarantee the quality of experience (QoE) for handover in the overlaid macro-femtocell networks. How to cope with the resource demand of handover calls is necessary to efficiently support the movement of mobile terminals, the QoE degradation or the load control. We attempt to satisfy the QoE requirements of users and maximize the capacity of the system at the same time. In order to achieve this goal, this scheme divides the shared resources into two part for the movement of MT and QoE degradation, and allocates those resources with the competition between four types of handovers. Simulation results show that our scheme provides better performances than the conventional one with respect to the outage probability, data transmission throughput.

Location prediction has been successfully utilized to provide high quality of location-based services to customers in many applications. In its usual form, the conventional type of location prediction is to predict future locations based on user's past movement history. However, as location prediction needs are expanded into much complicated cases, it becomes necessary quite frequently to make inference on the locations that target user visited in the past. Typical cases include the identification of locations that infectious disease carriers may have visited before, and crime suspects may have dropped by on a certain day at a specific time-band. Therefore, primary goal of this study is to predict locations that users visited in the past. Information used for this purpose include user's demographic information and movement histories. Data mining classifiers such as Bayesian network, neural network, support vector machine, decision tree were adopted to analyze 6868 contextual dataset and compare classifiers' performance. Results show that general Bayesian network is the most robust classifier.

A safety management system is a information system. This system finds out hazards which could occur during safety management activities, and analyze and evaluate their natures, and then plan to take measures. Therefore accidents could be prevented. To establish the information system, robust architectures are required. A purpose of this research is to derive procedure of establishment in relation to developing safety management systems, which is needed to be advanced. To accomplish it, we reviewed a movement of architectures to establish electronic information and a movement of technology development And then we led definitions of requirements and architectures development process from those that are based on review of the trends.

In the advent of the fourth industrial revolution, which was to become an innovative society, we now face the forefront of a technological revolution, and in response to these changes, the world is actively developing the maker movement to nurture new innovations. Accordingly, it is necessary to change the functions of the library in order to play a leading role in a changing life environment. In addition, it is necessary to present certain directions in policies in order to help expand the library's capabilities to utilize a cultural technology. In this study, we have conducted a survey on public library librarians' perceptions towards makerspaces, and based on this, we have proposed directions and support policies for public library's makerspaces and a dissemination structure of makerspaces for the public library.

This study is about the Spatial Composition and Area Calculation in Plastic Surgical Clinics. 1. The space of the plastic surgical clinics are divided into 4 sections; exam, exam support, the staffs, and waiting and reception area. 2. The average G/N ratio of width was 1.46. The Plastic surgical clinics which had great deviation in the ratio showed these characteristics; first, when they were planned at first, the operation rooms were not assigned enough space; second. space for supporting exam and the activities of staffs was given too little consideration in their first drafts. 3. The average size of operation rooms was $21.76m^2$. The most desirable size was found to be $26.4m^2$ when we put the number of staffs, the movement area of stretcher, and the movement lines of operation room into consideration.

This study aims to investigate present situations and problems of local Bookstart program, difficulties faced by local organizations in the course of them implementing the program, and awareness on institutional support system, and ultimately propose strategies for its activation. In particular, considering that public libraries with easier access to babies having highly limited mobility and accessability should be the base of the program, the essay focuses on strategies of its activation for public libraries.

In this study, an electronic parts assembly training system using Leap Motion was developed in consideration of the processes actually operated in the assembly process of electronic products. Based on Leap Motion and Oculus VR equipment, the system was developed to transfer user's hand movement data in real time and convert it into hand movement in virtual space so that electronic parts assembly simulation can be performed step by step. Through this, it was confirmed that the user can obtain an experience similar to the actual electronic parts assembly work, prevent errors that may occur during the assembly process, and improve proficiency. It is expected that this thesis will provide directions for the quality improvement and development of various education and training programs for virtual reality-based manufacturing processes.

The community mixed-support facility in Japan is making efforts to try various approaches according to the changes made to allow the privatization of public facilities on the basis of Act on Special Measures for Urban Regeneration since 2004. Due to this change in policy, the community mixed-support facility is now taking further steps in trying to implement variety of approaches in the perspective of urban regeneration and urban maintenance and at the same time the trend of installation of community facility has gone through vivid changes for the last 20 years. The causes of this are from the social demand that claims for of new facilities and the change in the subsidy system in relation to equality in facility installation. Examples of the first cause can be the building of perpetuating educational society, an execution or a movement towards the society of gender equality, a countermovement for an aging society as well as a welfare society, and recently social phenomenon related to consumption is becoming an issue. And for the last, the number of construction of facilities is increasing that grow out of the traditional facility system. The complex of community mixed-support facility will provide public administrative and community mixed-support services to local people as well as to form a notion of community and a feeling of solidarity. Ultimately, this will develop local areas by regional interchanging of information. In this very research, we will analyze the community mixed-support facility and its characteristics as well as its implications and consider the types of complex through many preceding instances in Japanese community mixed-support facility.
