The numbers of the elderly who suffer Empty Nest Syndrome have been accelerated as an aging population has increased vastly and nuclear families have been a dominating family type in modern Korean society. To make the elderly get out of this phenomenon and live actively, the scheme of converting their existing houses into shared houses was set as a hypothetical solution in this study, and finding out the responses of the elderly who owns their own houses is the purpose of the study. A small workshop panel method was used and the elderly aged 55 years upwards took part and they own a detached house that is relatively large for the elderly or the elderly couple to live alone. The workshop was consisted of 3 stages: 1. a survey 2. an interview 3. a site visit. Through this, problems that the elderly have been experiencing within their houses were looked into and the responses of the elderly on converting their houses to shared houses by introducing developed schematic plans. As a result, positive responses from the house owners were carried out based on the fact that subsidies from the government on house renovation and tenants matching programs are supported. Shared houses could provide home owners economical support with rents and help them to feel less lonely. This is one way of supporting the elderly to live and age actively in their later lives. Therefore, this idea should be established in connection with preparing aging, aged, and super-aged society.

In korean society, the chronic life style diseases are increasing. It is caused by the approach of the aged society and the highly increasing income. Accordingly the preventive side of the health promotion and management is very important. In the oriental medicine, the general disease pre-estimate and the management program are necessary. On this point, the sign forecast is very significant in connection with the disease pre-estimate in the preventive disease management side. The sign forecast according to the human shape type diagnosis is mainly the sign of the super-early stage, The difference of the shape type has the difference of the special affinity about the disease. Accordingly we can find the sign forecast from the latent disease in the early stage. In NAE-GYEONG(內經), the theory of "five body form's type" can be pre-estimated the latent tendency and the clue of the disease and the growing tendency of disease in relation to the Differentiation of Syndrome, In the disease pre-estimate side, the graspe and management of the sign forecast from the latent disease will be the part of the new development.

In recent years, the construction of high-rise buildings are promoted. According to these, there are many needs about new technologies to strengthen the building performance and high-strength steel is regarded as one of these for promoting building performance. In Korea, high-strength steels which stress are over 600MPa are on market and in aborad, super high-strength steels over 1000MPa are developing and they expected to promote the building performance. But there are still doubts about applying high-strength steel members because of size effect and worry of brittle fracture. In this reports, we propose results of performance and analysis tests for use with general steel. We propose the characteristic of high-strength steels first and next the results of performance test to show they satisfy the performance that designers expect. And last, we compare the results of test and analysis for acquire the alanysis reliability in non-linear analysis with high-strength steels.

The ubiquitous network revolution is beginning with the onset of digital convergence, whereby computers, horne appliances, and communications and broadcast media are being unified into digital media with the founding of the information super high speed. This technical advancement is creating a new culture and a new space and accelerating society's transition to the new and unique social paradigm of a 'ubiquitous society'. In particular, studies on ubiquitous communications are well underway. Lately, the focus has been on the Bluetooth technology due to its applicability in various environments. Applying Bluetooth connectivity to new environments such as ubiquitous or sensor networks requires finding new ways of using it. Thus, the scalable Bluetooth piconet scheme with independent slave device is proposed. It follows from work by Sea et al. But extended scatternet is not considered is Kiisc05 paper. Therefore, we propose secure bridge connection scheme for scalable Bluetooth scatternet.

As the size of container ships continues to increase, not many existing harbors can host the super-container ship due to its increased draft and the corresponding dredging requires huge budget. In addition, the minimization of waiting and loading/offloading time is the most important factor in harbor competitiveness. In this regard, mobile-harbor concept has been developed in Korea to achieve much improved harbor capacity and efficiency. In developing the concept, one of the most important elements is the operability of crane between two or more floating bodies in side-by-side arrangement. The container ship is to be stationed through a hawser connection to an outside-harbor fixed-pile station with the depth allowing its large draft. The mobile harbors with smart cranes are berthed to the sides of its hull for loading/offloading containers and transportation. For successful operation, the relative motions between the two or more floating bodies with hawser/fender connections have to be within allowable range. Therefore, the reliable prediction of the relative motions of the multiple floating bodies with realistic mooring system is essential to find the best hull particulars, hawser/mooring/fender arrangement, and crane/docking-station design. Time-domain multi-hull-mooring coupled dynamic analysis program is used to assess the hydrodynamic interactions among the multiple floating bodies and the global performance of the system. Both collinear and non-collinear wind-wave-current environments are applied to the system. It is found that the non-collinear case can equally be functional in dynamics view compared to the collinear case but undesirable phenomena associated with vessel responses and hawser tensions can also happen at certain conditions, so more care needs to be taken.

This research presents the actual situation analysis and suggestions for the changes, experiences, and process of adaptation that college students have experienced throughout their studies and life over the past two years and more. In-depth interviews were conducted with university students, who are educational objects, and qualitative analysis methods were used to explore the overall living experiences under the pandemic situation. The interview questions were composed to cover classes, life, and emotional experiences after COVID-19, and the result of analyzing the responses boiled down to four super-categories of 'adaptation process to a new system, daily incontinence, struggle for health, and longing for connection.' This study is significant in that it analyzed the experiences and intimate changes of individual college students in unexpected and challenging situations, and urged the myriad aspects that universities, society, and the government should illuminate and respond to.

This study aims to analyse the U-City characteristics through the U-City historical mapping. The U-City characteristics were analysed by building the U-City historical map in terms of STIM model which consists of service, technology, infrastructure and management. The data for analysis is the National Informatization White Paper published by the NIA (National Information Society Agency) from 2002 to 2013. As a result, first, the U-City service were evolved from administration informatization, enterprise informatization, administration/living informatization and administration/space/private informatization through the intelligence facilities and space. Second, the U-City technology were changed through wire network, sensor/network, processing/super-highway network, convergence of network/security. Third, the U-City infrastructure have had evolutionary process such as wire computer network, wire/wireless network, intellectualization facility and intelligent facility space. Forth, the U-City management were carried out with making the unit network/infrastructure management, information connection/operating management and information integration/participation management. Therefore, the history of U-City has been making rapid development in government computerization, computer oriented society, information city and ubiquitous city.

Currently, finding one's way in the underground spaces associated with subway stations in large cities is becoming a serious problem, and an environment that facilitates wayfinding is becoming more important. This study investigated interior treatments that function as visual cues in the subway stations of Seoul, Tokyo, and Taipei in order to develop design guidelines that would improve the place-cognition environment. A theoretical study has shown that there are three categories of visual cue for place cognition: marked trails, regional differentiation, and landmarks. The case study showed that marked trails involve treatments like vertical markers, confrontational positioning, and subway color codes. Regional differentiation involves patterns on the floors and walls, and accent colors on the walls and columns. Landmarks include treatments such as super graphics, symbolic features, artistic decoration and special lights. In the cases of Seoul, marked trails and regional differentiation were predominant. In addition, the Olympic symbol 'Hodori' and the ancient Korean character "Hunminjungeum" were used as landmarks. In the cases of Tokyo, regional differentiation predominated over marked trails because of the complexity of the spatial structure and subway line connection system. In the cases of Taipei, simple, unified images predominated, and there was minimal dependence on marked trails and landmarks. The need for regional differentiation was weak, because the stations studied have open structures that guarantee an open field of view. The results of this research could be used as design guidelines, after further experimental verification, that would help to improve the public environment in terms of wayfinding.

The KOINONIA is developed to communicate with connection of the short-range devices by the technique of the WPAN. The piconet consists of one master and slaves above one, the multi-poconet consists of parent piconet and child piconets which is formed the basis of parent piconet. The child piconet consists of the child master and slaves. The child master takes a role of the master in the child piconet and the slave in the parent piconet. In this paper, the multi-piconet is made as above, then we estimate the max capacity of assigned CTA by level, number of slaves in child piconet. A super-frame is the maximum 65.535ms of usable capacity. Because of it is a fued number, We suggested quantitatively the fixed reduction of an usable capacity by increases of number of slave and child-master in the piconet. And we analyze the reduction of an available capacity by the increase of number of child piconet.
