In recent, the direction of water resources policy is changing from the typical plan for water use and flood control to the sustainable water resources management to improve the quality of life. This change makes the information related to water resources such as data collection, management, and supply is becoming an important concern for decision making of water resources policy. We had analyzed the structured data according to the purpose of providing information on water resources. However, the recent trend is big data and cloud computing which can create new values by linking unstructured data with structured data. Therefore, the trend for the management of water resources information is also changing. According to the paradigm change of information management, this study tried to suggest an application of big data and cloud computing in water resources field for efficient management and use of water. We examined the current state and direction of policy related to water resources information in Korea and an other country. Then we connected volume, velocity and variety which are the three basic components of big data with veracity and value which are additionally mentioned recently. And we discussed the rapid and flexible countermeasures about changes of consumer and increasing big data related to water resources via cloud computing. In the future, the management of water resources information should go to the direction which can enhance the value(Value) of water resources information by big data and cloud computing based on the amount of data(Volume), the speed of data processing(Velocity), the number of types of data(Variety). Also it should enhance the value(Value) of water resources information by the fusion of water and other areas and by the production of accurate information(Veracity) required for water management and prevention of disaster and for protection of life and property.

In the medical environment today, new technology has compelled new work paradigm, as it has been other areas of our lives. However it is very difficult to see the changes that have been taken place, even though new computer technology has changed the medical industry so rapidly. In this study, new concept of human computer interaction focusing on tangible interaction for anaesthetic procedure in an operating theatre has been explored with a 5 years technological and social perspective. This project is not intended to redesign the equipment itself but to focus on enhanced human computer interaction concepts. The exper iment shows that how new technology affects anaesthetic nurses' work in an operating theatre in the near future to improve quality of the medical service by helping to increase work efficiency and enhance patient satisfaction. As a result of the study, the KEY brings new visions to the anaesthetic nurses via various types of interaction. Thanks to the KEY, the nurse is really free from the machines so that he can keep attention to patient most of the time during the whole operation. The discussion in this study is still preliminary, and further elaboration is strongly needed. It might be certain that additional further studies, such as high-fidelity prototyping and logistical user testing, should be followed not only to refine and communicate the ideas to audiences, but as a means of stimulating and generating further ideas.

A unit modular system is a construction method which installs on site by manufacturing 50%~90% of the whole process in the factory. This method can minimize the process in the site and maximize the operation, which will reduce the duration and improve the overall quality. The recent paradigm of construction is to be sustainable building. Modular system can be regarded as a sustainable building construction method because it can reduce the amount of construction waste by recycling partial or whole part of overdue building be torn down. A unit modular system is the answer to cope with the increasing market of small size housings. A unit modular system is the most appropriate option at this point. This research proposes the standard operation and construction process of modular system, which enable to optimal system. A case study of reconstructing small-size housing was introduced to support this proposal. Finished unit modular is the reasonable way. However, 80% of complication rate of the modular is the most rational when a defect occurrence during delivery is considered.

Background: The recent change in pharmaceutical education system following the paradigm shift to patient-oriented pharmacy service requires an in-depth discussion to reorganize a future direction and establish a basis for maximizing social values of community pharmacy service. Objective: This study was conducted to review the current status of community pharmacy service provision in Korea based on published literatures. Methods: The electronic databases of National Digital Science Library and Electronic National Assembly Library were used to search the journal articles and dissertation papers. A search term "community pharmacy" was used and the published period was limited to papers published after year 2001, when the legal separation of prescribing and dispensing was implemented. Relevant study reports were also searched manually. Information about pharmacy service provision and study outcomes were retrieved from the selected papers, and classified by predefined individual service scope. Results: A total 33 papers reporting services provided by community pharmacies were selected (journal article 11, dissertation paper 17, and study report 5). Pharmacy services identified in these papers could be classified into prescription dispensing service, pharmaceutical care service, self medication service, other products service, and health promotion service. Twenty papers reported prescription dispensing services, three papers reported pharmaceutical care service, and only two papers reported health promotion service. Current community pharmacy services are highly dependent on prescription drugs while expanded services such as pharmaceutical care and health promotion are peripheral. Most prevalent research topic was medication counseling service (18 papers), reflecting that community pharmacists generally consider it to be the most important and fundamental service. Overall, current pharmacy services are very limited and focus on prescription dispensing service. Conclusion: At this point of time requiring expansion and quality improvement of community pharmacy services, we suggest further lively discussion to strengthen pharmacist's functional identity and set conditions for providing socially expected services.

Compressive Sensing (CS) is a new signal acquisition paradigm which enables sampling under Nyquist rate for a special kind of signal called sparse signal. There are plenty of CS recovery methods but their performance are still challenging, especially at a low sub-rate. For CS recovery of natural images, regularizations exploiting some prior information can be used in order to enhance CS performance. In this context, this paper addresses improving quality of reconstructed natural images based on Dantzig selector and smooth filters (i.e., Gaussian filter and nonlocal means filter) to generate a new regularization called smooth residual error regularization. Moreover, total variation has been proved for its success in preserving edge objects and boundary of reconstructed images. Therefore, effectiveness of the proposed regularization is verified by experimenting it using augmented Lagrangian total variation minimization. This framework is considered as a new CS recovery seeking smoothness in residual images. Experimental results demonstrate significant improvement of the proposed framework over some other CS recoveries both in subjective and objective qualities. In the best case, our algorithm gains up to 9.14 dB compared with the CS recovery using Bayesian framework.

Used gas to the vehicle fuel are the problems of the 'survival' beyond the 'quality of life' improvements and revive a new paradigm of 'sustainable development' which pursues economic development in harmony with environmental conservation. However, the fatalities caused by explosions and fires increases every year with the increase in the use of LPG; gas accidents in large-scale storage facilities also cause severe damage to property. In this study, a suitable storage tank is designed in which the surface area of the fuel exposed to flames is minimized in order to prevent explosions; thus, the occurrences of explosions in underground storage tanks can be minimized. According to the optimum design of storage tank obtained in this study, underground containment space was minimized; the minimized diameter and length of a 20-ton storage tank was 3 m and 4.83 m, respectively. Thus, safety was ensured since surface area exposed to flames decreased by 89.4%, which is less than the exposed surface area in the currently used storage tanks.

In the past, expressways focused on mobility. However, the paradigm of expressways fuction today has been changed from fast expressways to safe expressways as people's quality of living and consciousness level heightened. In 2012, 3,550 traffic accidents occurred on expressways and 371 people died. The fatality rate of traffic accidents on expressways is almost twice that on general national roads. This study developed accident forecast models (safety performance functions) based on the number of traffic accidents and traffic volumes on six major lines on expressways. It is difficult to forecast safety performance functions for each expressway line because the lines and the scales of expressways are different from each other; therefore, integrated safety performance functions of six lines were determined first, and the coefficients, which can correct the traffic accidents on each line, were calculated. It is believed that this study will contribute in the safer management of expressways by being used as basic information in the establishment of traffic safety strategies for each expressway line in prevention of traffic accidents. Moreover, more studies would be required in the future, which would suggest reliable accident forecasts by calculating correction coefficients by line through integrated models by groups dependent on the characteristics of each line.

Because of development of information technology, moving picture can run various platforms. We should consider and apply users' attitude as well as production technique because convergence between mobile and media technology may be increased full-browsing service using mobile device. Previous research related to production technique in various platforms only focus on video quality and adjustment of screen size. However, besides of technical side, production techniques should be changed such as image production as well as image editing by point of view aesthetic. Mise-en-scene such as camera angle, composition, and lighting is changed due to HD image. Also image production should be changed to a suitable full-browsing service using mobile device. Therefore, we would explore a new suitable production techniques and image editing for smart phone. To propose production techniques for smart phone, we used E-learning production system, which are transition, editing technique for suitable converting system. Such as new attempts are leading to new paradigm and establishing their position by applying characteries such as openness, timeliness to mobile. Also it can be extended individual area and established as expression and play tool.
