전 세계적인 저성장 기조로 인하여 주요 선진국에서는 도시축소문제가 도시정책의 주요 이슈로 대두되고 있다. 국토연구원의 연구결과(2016)에 따르면 우리나라 77개 도시 중 23개 도시가 지속적 또는 일시적 축소도시로 진단되었다. 그러나 축소도시를 진단하는 기준은 단순한 인구통계학적인 측면에 머물러 있으며, 도시의 공간적 축소패턴은 고려되지 않고 있다. 따라서, 본 연구에서는 도시공간구조 분석방법의 하나인 인구밀도경사함수를 이용하여 다핵도시인 영주시의 특성을 고려한 도시축소현상을 진단하였다. 진단결과, 영주시는 CBD의 인구밀도 및 인구밀도경사도가 증가하는 축소도시의 특성을 보이고 있다. 동지역의 경우 CBD의 인구밀도 및 인구밀도경사도가 감소하는 스프롤(sprawl) 현상이 나타났다. 또한, 풍기읍의 경우 CBD의 인구밀도만 감소하는 단순축소 현상이 나타났다. 본 연구결과는 한 도시 내에서도 중심지마다 공간변화의 패턴이 상이하게 나타날 수 있다는 것을 보여주었으며, 다핵구조를 갖는 도시의 경우에는 도시 전체뿐만 아니라 세부 지역에 대한 개별적인 진단이 필요하다는 시사점을 도출하였다.

Interactive space became one of the modern contemporary society design paradigms. For elevating the interactive effect, we need Interactive design development which uses the influential factors on the interactivity. Digital technology is resulted in a change to a society as well as to the life of human and its way of communication. This study is inquiry into the relations and the common characteristics between ecological architecture space and eco-centric environmental philosophy by making a comparative research. This aims to examine type of spatial contexts for performed through literature research for theory by interactive space and case studies for ecological construction elements to design. And the range of case study is limited to interaction space in addition of interactive elements and user interface. And analysis conclusion is show the many type. Five principles that draw at ecological design conceptualization process, whole unity, variety of organic at ecological design conceptualization process, circularity, homeostasis, allness, biological evolution, diversity have involved with concept that presents in ecological esthetics and organic property of ecology-system.

For enhancing network efficiency, content-centric networking (CCN) allows network nodes to temporally cache a transmitted response message(Data) and then to directly respond to a request message (Interest) for previously cached contents. Also, CCN is designed to utilize a hierarchical content-name for transmitting Interest/Data instead of a host identity like IP address. This content-name included in Interest/Data reveals both content information itself and the structure of network domain of a content source which is needed for transmitting Interest/Data. To make matters worse, This content-name is human-readable like URL. Hence, through analyzing the content-name in Interest/Data, it is possible to analyze the creator of the requested contents. Also, hosts around the requester can analyze contents which are asked by the requester. Hence, for securely implementing CCN, it is essentially needed to make the content-name illegible. In this paper, we propose content-name encoding schemes for CCN so as to make the content-name illegible and evaluate the performance of our proposal.

Nuclear Power Plant consists of about 1.4 million facilities. and the design standards and design requirements for the continuos utilization and safety of facilities are complexly connected with the facilities. When a design change for facilities or design requirements is occurred at the time of construction or operation, there are a lot of facilities, design requirements, and design bases that are affected by the facilities or design bases being changed. The above design changes are so complex that the existing document-bases design change process is time-consuming and may also cause human error. In this study, we developed a design requirement taxonomy that can be applied to the data-centric design bases document that can improve it. To do this, we analyze the design elements from the highest level to the lowest level applied to the nuclear power plant, and classify the design elements according to the characteristics of the design elements.

Smart lighting systems have become increasingly popular in several public sectors because of trends toward urbanization and intelligent technologies. In this study, we designed and implemented a web application platform to explore and monitor data acquired from lighting devices at Thammasat University (Rangsit Campus, Thailand). The platform provides a convenient interface for administrative and operative staff to monitor, control, and collect data from sensors installed on campus in real time for creating geographically specific big data. Platform development focuses on both back- and front-end applications to allow a seamless process for recording and displaying data from interconnected devices. Responsible persons can interact with devices and acquire data effortlessly, minimizing workforce and human error. The collected data were analyzed using an exploratory data analysis process. Missing data behavior caused by system outages was also investigated.

This study searched fundamental basis of four-constitution medicine from the principle of "Yeokgyeong(易經)" that is scientific foundations of Dongmu(東武) Ijema(李濟馬)'s four-constitution medicine based on system of "Yeokgyeong(易經)" and looked into the principle of our-constitution medicine ontologically. That is to say, the translation of five phase(五行) that represented in "Hwangjenaegyeong(黃帝內經)" regulated that substance of five phase is spleen-earth(脾土). But four-constitution medicine mentions the substance as heart-earth(心土) in place of spleen-earth. Because of it's standpoint, the differences on meanings between spleen-earth and heart-earth on the substance of five-phase becomes motive to interpret scientific system of four-constitution medicine fundamental wrongly. For that reason, the research of this title is needed. The results was summarized as follows. First, in ontological view point of structure of four-constitution, five phase is substance and phenomenon, in other words it includes earth of unrevealed substance and wood, fire, metal and water of self-manifestation of existence. Second, in axiological view point, the four-constitution represent principles and contents of four virtues of human nature. And so the innate four virtues ontologically based on four-constitution of heaven. Therefore a human being is endowed innately benevolence, courtesy, justice, intelligence of four virtues. Third, the concept of greater and lesser of Eum(陰, yin) and Yang(陽, yang) in Dongmu(東武)'s four-constitution medicine is four-constitution in "Yeokgyeong(易經)". Greater principle(太極) and four-constitution is a relation of substance and phenomenon. Fourth, the origin and structure of four-constitution medicine includes the structure and principle of natural philosophical Eumyang and four-constitution, the human-centric theory and sciences of human nature and natural laws and medical experience of traditional oriental medicine and medical principle.

According to our recent investigation that the increase in the occlusal vertical dimension made the appendage muscle strength got higher, the occlusal appliances were made by increasing the occlusal vertical dimension "from the centric relation" position of the mandible. In this experiment, the authors tried to study the change in the appendage muscle strength due to increase in occlusal vertical dimension from intercuspal position(ICP) of mandible with the same subjects and manner as the former experiment. For this study, ten male athletes in a mean age of 23 year who were joined the former study were selected. All the subjects had a complete or almost complete set of natural teeth and reported no subjective symptoms of temporomandibular disorders. Upper and lower casts were mounted on the semi-adjustable articulator at the intercuspal position and a point was marked on the attached gingival area between the right canine and the right 1st. premolar in each upper and lower cast. From the points, the occlusal vertical dimension was increased by 2mm, 3.5mm and 5mm, and then each 10 maxillary type occlusal splint at each 3-increased position were fabricated with heat curing clear acrylic resin. Including the intercuspal position, the 3 kinds of occlusal splints were placed on the subjects individually, and then isokinetic muscle strength on 7 parts of the human appendage which are shoulder, knee, ankle, wrist, forearm, elbow and hip was measured with the CYBEX 6000 SYSTEM (Lumex, NewYork, USA). The results were as follows: The highest mean value in muscular strength was shown at the position of 2mm-increased vertical dimension. The muscle strength during internal/external rotation of shoulder and knee, plantarflexion of ankle, flexion of elbow, and flexion and extension of hip at the increased occlusal vertical dimension position were significantly higher than them at the intercuspal position (p<0.05). Only in view of the increase in the appendage muscle strength, regardless of the way of making the occlusal splints by elevating the occlusal vertical dimension from the centric relation position or intercuspal position, the occlusal splints had an effect on the increase of isokinetic muscle strength at the occlusal vertical dimension which increased within the proper range on the habitual arc of closure.
