Objectives : To gather information about the factors which influence the interest and intention of admission into charging nursing hones for the elderly(CNH), as these homes represent an important method for resolving the problems related to the rapid population aging occurring in Korea. Methods : A face-to-face interview survey was carried out with 320(men 159, women 165) patients over 60 years old who were admitted at 2 university hospitals and 5 general hospitals in the Busan area between December 1998 and March 1999. Data were analyzed through t-test, ANOVA, correlation and multiple regression analysis. Results : The mean age and years of education of the study population was 67.0 and 7.7 years, and the types of chronic degenerative disease included musculoskeletal disorders(20.1%), cerebrovascular disease(17.1%), and diabetes(14.3%). The major forms of household living arrangement prior to admission were elderly alone(22.6%), and elderly couple(33.5%), while about half of them(55.5%) didn't want to live with their children id the future. Almost half were paying medication fees by themselves(46.6%). The level of actual intention of admission$(3.07{\pm}1.39)$ into a CNH was lower than that of interest$(3.22{\pm}1.33)$(p<0.01). Multiple analysis revealed that the intention of admission increased with decreasing number of future supportive persons$(\beta=-0.107)$, lower level of activity in daily life$(\beta=-0.447)$, and longer years of education$(\beta=-0.447)$ with 32.7% of $R^2$. As for the factors which determined the admission into a CNH, the fee and facilities were considered to be most important, and professional nursing and physician's care were the most desired services. In nomenclature, they preferred 'elderly hospital' or 'elderly health center' to CNH. Conclusions : Interest in CNH is increasing recently, but existing studies about patient experiences in CHN are still limited. This study may form a basis for future examinations of the needs and uses for CNH. Active financial support and public information are considered by the authors to be important factors for the induction of welfare services for the elderly, though CNH.

This paper is the output of a collaborative European project concerning the barrier free accessibility for disabled persons to regional and long distance trains in Europe. Disabled people represent around 13% of the population in Europe. This is approximately 63 million people. The range of disabilities includes people with reduced mobility including wheel chair users, viewing and hearing impaired people and other forms of impairment. Improving accessibility aims at contributing to the provision of public transport services to all citizens in an equitable way. The purpose of the project was to analyse and to evaluate the existing solutions at selected European railways for all required modules at the entrance (doors, information and safety solutions), to derive a design concept, to develop a mock-up in meeting the needs of rail travellers with the above mentioned impairments and to test it with user groups. The project also aims at deriving components for the determination of standards. The EUPAX Design Mock-up test was performed to verify the advantages of the layout of the train segment including the different modules such as access area (including the access door, gaps between platform and train as well as boarding aid devices), entrance vestibule, information systems inside and outside the train, emergency facilities, toilet with all conveniences and the additional test arrangements regarding push buttons, steps and emergency equipment. For this purpose a questionnaire was developed for the assessment of the EUPAX segment and the additional test arrangements. With the help of this questionnaire it was possible to execute a quantitative and qualitative evaluation. During three test phases 67 experts and handicapped persons from 6 countries have evaluated the Industrial Design mock-up based on this questionnaire. The test group covered persons from North (Denmark) to the South (Italy) and from the West (Spain) to the Middle of Europe (Germany). This is especially important for the generalization (harmonisation) of the results for all European countries. According to COST 335 the information for people with reduced mobility should be clear, concise, accurate and timely. So that all information can be received from persons, they must be transferred on at least two of the three possible ways (acoustical, visual, tactile), a so called "2-sense-principle". Based on the results ergonomic specifications/ solutions for the ergonomic design of the access area, the acoustic, visual and tactile information and the emergency devices including the emergency communication system were developed, related to the benefiting passenger groups.

Libraries are one of the essential living infrastructures in urban regeneration. Beyond its meaning as a basic living infrastructure, it is necessary to first understand the role, nature and forms of participation in existing urban regeneration projects in order for libraries to perform their functions and roles effectively as participants of urban regeneration. Therefore, this study investigates the contents related to libraries in the contents of the strategic plan related to urban regeneration projects, and considers them in terms of the role of the library and the form of participation. Through this, the city's library would seek to maximize its role and function as a participant in urban regeneration. As a result, the library in urban regeneration is expected to improve the quality of living environment, Urban vitality, culturally, educationally, socially/welfare role closely related to life, and the role of community as a hub. In addition, the types of library participation could be largely divided into regional and geographical libraries, hybrid libraries combined with various services, libraries based on community cooperation and linkage, and regional community hub libraries based on community participation. In the future, the library needs to promote a more active role change based on the five roles expected as participants in urban regeneration. In addition, more detailed discussions on librarians, services, and programs, which are the main subjects of library services, will be needed in developing urban regeneration plans in order for libraries to successfully fulfill their role as urban regeneration centers.

Modern high technology has developed from a printing type-oriented culture to sight and hearing-oriented one. Such changes helped raise users' interests and desires on being seen and heard, encouraging research for various usages and types. In particular, with the common use of high speed Internet and firmer standing of Internet as advertising media, Internet banner advertisement has been growing twice as much as the previous year, every year. With this accelerated development of multimedia Kinetic Typography has been used for a variety of forms. During this series of process, the most important one is the expression of the movement of Kinetic Typography. Information able to obtain from the existing way of reading became transferred to the process of multi-dimensional process of obtaining such as seeing and hearing. Accordingly, more effective expression with interesting factors considered together with more activeness for users' obtaining information through Internet, can expect more positive effects. Towards this goal, more various new tries should be made for Internet banner advertisement. In particular, with the larger role in Kinetic Typography to play the role of users' reading for information obtainment, the principles & factors of expression for Internet banner advertisement would be studied, and expression types and structure would be considered, and data from them would be collected and analyzed, to suggest the direction of development.

This paper presents the implementation and design of the advanced WI-FI systems with beam-forming antenna that radiate their power to the direction of user equipment to improve the overall throughput, contrast to the general WI-FI systems equipped with omni-antenna. The system consists of patch array antenna, DSP, FPGA, and Qualcomm's commercial chip. The beam-forming system on the FPGA utilizes the packet information from Qualcomm's commercial chip to control the phase shifters and attenuators of the patch array antenna. The PCI express interface has been used to maximize the communication speed between DSP and FPGA. The directions of arrival of users are managed using the database, and each user is distinguished by the MAC address given from the packet information. When the system wants to transmit a packet to one user, it forms beams to the direction of arrival of the corresponding user stored in the database to maximize the throughput. Directions of arrival of users are estimated using the received preamble in the packet to make its SINR as high as possible. The proposed beam-forming system was implemented using an FPGA and Qualcommm's commercial chip together. The implemented system showed considerable throughput improvement over the existing general AP system with omni-directional antenna in the multi-user communication environment.

Recently, unconventional high-rise building shapes have attracted attention as a landmark of metropolitan cities and the search for innovative building forms in architecture is ongoing. In this study, $Isotruss^{(R)}$ grid(ITG) used in smaller scale structures was applied to building structural systems and its structural performance was examined. The structural behavior of an ITG was compared with that of a diagrid structure as a reference structure. The stiffness-based design method of the diagrid system was used for the preliminary design stage of member sizing in an ITG. The structural design of 16, 32, and 48-story buildings was carried out for the two systems with the same size. The angle of the inclined columns for ITG and diagrid was $59^{\circ}$ and $68.2^{\circ}$, respectively. The lateral stiffness, steel tonnage of the exterior frame, axial strength ratio, story drift ratio, and natural frequency of the two systems were compared. Based on the analysis result of 6 buildings, the two systems had similar structural capacity; 93.3% and 88.7% of the lateral load was carried by the perimeter frame in the ITG system and diagrid system, respectively. This suggests that the ITG system is better in arranging core columns. Therefore, the proposed ITG system has not only a unique façade, but also substantial structural capacity equivalent to the existing system.

In order to measure the deposition velocity of $I_2$ vapor for radish plants and its translocation factor for their roots, radish plants were exposed to $I_2$ vapor for 80 min. at different growth stages between 29 and 53 d after sowing. The exposure was performed in a transparent chamber during the morning time. Deposition velocities ($ms^{-1}$) were on the whole in the range of $1.0{\times}10^{-4}{\sim}2.0{\times}10^{-4}$ showing an increasing tendency with an increase in the biomass density. The results showed some agreement with existing reports that a higher relative humidity would lead to a higher deposition velocity. The acquired deposition velocities were lower than by factors of several tens than some field measurements probably due to a very low wind speed (about $0.2\;ms^{-1}$) in the chamber. Translocation factors (ratio of the total iodine in the roots at harvest to the total plant deposition), estimated in a more or less conservative way, were $1.3{\times}10^{-3}$ for an exposure at 29 d after sowing and $5.0{\times}10^{-3}$ for an exposure at 53 d after sowing. In using the present experimental data, meteorological conditions and chemical and physical forms of iodine need to be carefully considered.

Recently, circulating ransomware is becoming intelligent and sophisticated through a spreading new viruses and variants, targeted spreading using social engineering attack, malvertising that circulate a large quantity of ransomware by hacking advertising server, or RaaS(Ransomware-as-a- Service), from the existing attack way that encrypt the files and demand money. In particular, it makes it difficult to track down attackers by bypassing security solutions, disabling parameter checking via file encryption, and attacking target-based ransomware with APT(Advanced Persistent Threat) attacks. For remove the threat of ransomware, various detection techniques are developed, but, it is very hard to respond to new and varietal ransomware. Accordingly, in this paper, find out a making Signature-based Detection Patterns and problems, and present a pattern automation model of ransomware detecting for responding to ransomware more actively. This study is expected to be applicable to various forms in enterprise or public security control center.

Regarding countless network disorders or invasions happening nowadays from 2014 until 2015, illegal access intended to attack through the communication line provided by ISP (Internet Service Provider) appears to be the source of the problem. As a defensive way to prevent such network-based attacks, not only stabilization structures for network communication but various policies as well as physical security devices and solutions corresponding to those have been realized and established. Therefore, now is the time to gain foundational research data to secure network security sections by producing logical area on communication bandwidth or such, suggest tasks to expand the communication line which is another research topic in the network security market, and recognize the fact that the active communication bandwidth linkage paradigm using network communication bandwidth is needed as one of the areas that can realize physical security. Additionally, it is necessary to limit the data in the forms of organizing visible security structures into a certain range of physical information by re-dividing communication capacity being currently provided by telecommunicators into subdivided organizational areas and applying the logical virtualization of communication capacity in each of the areas divided. By proposing a network security section based on a logical field application in place of the existing physical structure, basic data that designs a stable physical network communication structure will be provided.
