This study aims to find out about the traditional life and consciousness of the Yi dynasty used its residence as the place where rites of passage were heid. This study is tuying to classify the rites of passage according to the procedures by which those rituals are being held and to analyze them based upon the space where rituals take place. The results of research and analysis are as follows : 1. The most frequently used area in the house as a variety of ceremonies were held includes SARANGBANG and DAECHUNG belonging to SARANGCHE and ANBANG and DAECHUNG that belong to ANCHE. So naturally these areas are located in the main space of the house. 2. ANMADANG as well as SARANGMADANG was used as the main walkway in the house and as the main place for the ceremonies such as marriage and funenal. MADANG space in the house played a semi-indoor-space fole andperformed the functions which limited indoor space couldu's carry out when ceremonies took place. 3. It seems that SADANG had net been utilized in the daily routine but located within the residence due to the ritualism.

The Norwegian architect, Sverre Fehn who was born in 1924 and died in 2009 designed various buildings in his country. Since he studied architecture, he had been interested in the domestic/local architectural environment as well as international modern movement such as CIAM. Pavilion of the Nordic Nations designed in 1960s gave him world reputation for the peculiar design characteristic in which Scandinavian tradition and modern design were integrated. Fehn introduced his unique architectural philosophy that is called 'Platform Architecture'. This concept is based on the Fehn's long-term interest in the philosophy of Genius Loci and place-specificity. It consists of three theoretical elements: Tectonic of Place, Horizontality of Space and Visual-Perception by Light. This paper focuses on three case projects: Villa Busk in 1990, Norwegian Glacier Museum in 1991, Aukrust Museum in 1993. It is aimed to discover differences as well as similarities of the projects, and ultimately to summarize the cases under the light of 'Platform Architecture'. As a conclusion, it is found that each case project has unique spatializing method to organize the given place and program by 'Platform' architectural design. 'Platform Architecture' is still relevant in the contemporary architecture and interior design because of its deep consideration on place, environment and human.

The temperature control of in-place concrete is the most important factor for an early age of curing concrete. Heat stress of mass concrete caused by the heat of hydration can induce the crack of concrete, and a frost damage from cold weather casting concrete results defect on compressive strength and degradation of durability. Therefore, success and failure of concrete work is dependant on the measurement and control of concrete temperature. In addition, the compressive strength assessment of in-place concrete obtained from the maturity calculated from the history of temperature make a reduction of construction cycle time, possible. For that purpose, wireless temperature measuring system was developed to control temperature and assess strength of concrete. And, it was possible to monitor the temperature of concrete over 1km apart from site office and to take a proper measure; mesh-type network was developed for wireless sensor. Furthermore, curing control system that contains the program capable to calculate the maturity of concrete from the history of temperature and to assess the compressive strength of concrete was established. In this study, organization and practical method of developed curing control system are presented; base on in-place application case.

Place names of road sign mean various place names being used on road signs for path guidance of drivers such as administrative district, facility, road, etc. It is very important that not only the choice method of place names for connectivity of road signs but standard establishment of spatial impact zone according to place names. However this standard are not established currently, so it is difficult to fix the spatial range for changing place names around the main facility according to the new construction or relocation of main facility in urban region. Considering the use of big data, one of the Government 3.0, we need to utilize actively the road sign management system database. This paper suggested a methodology for standard establishment of spatial impact zone according to place names of road sign in urban regions based on the road sign management system database. To perform a case study, we selected a major facility ("City Hall") which is the most frequently used the place name of road signs and presented standard of spatial impact zone by urban size in 84 cities.

Space and place have distinctively different meanings from each other. As virtual reality has become a routine of daily life, placeness concepts have been introduced on discussion tables. Yet, place has not been widely discussed in conceptual approaches Thus, using the concepts of space and place this study attempts to figure out the structure and the processes of how users recognize digital space and give placeness. For the study purpose, it identifies core elements of placeness attribution in digital game places, and then explains the development processes of space into place through characteristics of MDA(Mechanics-Dynamics-Aesthetics)framework. Based on present theoretical concepts and their application process this study also demonstrates the transformation process through which physical space becomes a place in the similar context with a necessary condition in order for a space to be a place. This study confirms that digital games can be transformed into a space that creates placeness in the process. Considering that players' affinity and nostalgia are generated through the placeness acquiring process in digital game space, the processes eventually imply an extension of largely meaningful and influencing contents as digital games induce players' immersion.

This study aimed to find out the formation of ecologically educational place identity of nature trails in national parks, which elementary school students to adults can understand, by analyzing the connectivity between characteristics (signs) of nature trails and elementary science environment-related key concepts and the domain of ecological education in the course of environment and by developing a semiotic interpretation model of place identity based on Barthes's semiotic theory. When analyzing correlations between the interpretation board-focused surrounding environment of nature trails and the content system of ecological education, this study found out that it showed the highest connectivity with the domain of 'System of Ecological Environment'. When analyzing the formation of place identity of nature trails in terms of semiotics, this study discovered that geographical locations or landscapes, artificial environments and physical elements as characteristics of surrounding environments mostly acted on the formation of placeness. Besides, it was found that both knowledge and attachment elements equally could act on the formation of a sense of place. Being likely to develop through interaction between placeness and a sense of place, place identity was mostly composed of behavioral internal stages and sympathetic internal stages. To diversify the formation of place identity, however, this study found it necessary to develop environment education projects and create surrounding environments and interpretation boards with the environmental uniqueness of nature trails reflected much more.

With the growing acceptance of the educational benefits for the use of robot- based teaching, their use in classrooms is increasing. However, the vast majority of studies taking place are based within normal classroom environment. Therefore, this study was focused on the adaptations that need to be made for the use of robot-based teaching within a special-needs environment, specifically a program for pre-service teachers of a special needs Elementary school. The results indicate robot-based teaching has a place within special education and it is hoped that this study will spur further investigation into the field.

Mobile IP has been designed only to maintain communication as they move form place to place, so it doesn't guarantee Quality of Service(QoS). QoS in mobile IP is important to provide multimedia and real-time applications services in mobile, and it is closely related to handoff delay. Therefore, handoff delay problem is actively studied to guarantee QoS as a main issue in mobile IP research area Next generation Mobile IPv6 resolve this problem somewhat, triangle problem for first packet and handoff delay still remain. In this paper, we suggest SNMP Information-based routing that adds keyword management method to Information-based routing in active network in order to resolve such a problem, and then suggest QoS controlled handoff based on SNMP Information-Based routing. After modeling of suggested method and existing handoff method simulations we carried out with NS-2 for performance evaluation. The results of simulations show the some improvement on handoff delay, and therefore on QoS improvement.

Nowadays, in the so-called 'smart era', people are likely to feel more comfortable in on-line meetings than in off-line meetings. However, on-line meetings are often considered unimportant and it is difficult for participants to share their feelings. This paper suggests a mobile application that can revitalize off-line meetings to address these problems. Wecok Application, which suggests the best meeting place by applying users' preferences and their locations, provides a function-oriented user interface and simple touch flow. Wecok consists of a client/server software, and currently supports only three users simultaneously. It enables exchange of off-line and on-line communication by expanding meetings from on-line to off-line. By using Wecok, users can easily decide on an off-line meeting place.

PURPOSES : The purpose of this study is to analyze the performance life of hot central plant recycling (HCPR) and hot in-place recycling (HIR) pavements applied to the National Highway for the past 20 years and compare it with conventional hot-mix asphalt (HMA) pavement. METHODS : In order to analyze the performance life of recycling asphalt pavements, a comprehensive literature review was conducted to investigate the government law and official system for the use of recycling asphalt pavement in Korea and foreign countries. Next, the application information of using a hot central plant recycling and hot in-place recycling pavements in the national highway is collected from the database of pavement management system (PMS) and then their field condition is visually surveyed. Finally, the performance life of recycling asphalt pavements in the national highway is analyzed and compared with conventional hot-mix asphalt pavement. RESULTS :Institutions are encouraging the promotion of using recycled asphalt pavement through various legal systems in Korea as well as abroad. Based on analysis results for the average performance life of hot central plant recycling pavement applied to the national highway, the average performance life is estimated to be 10.2 years. However, the average performance life of in-place recycling pavement is estimated to be 6.5 years. However, it is expected to increase performance life after the HIR construction system is modified. CONCLUSIONS : Based on the limited data analysis of the performance life of recycled asphalt pavements, HCPR shows similar performance life to conventional asphalt pavement but HIR shows shorter performance life than conventional asphalt pavement. However, it is noted that all performance life data is very limited and it should be monitored and analyzed further.
