Objectives: Although vaccination rates have increased, problems still remain in the storage and handling of vaccines. This study focused on inspecting actual vaccine storage status and awareness, and comparing them before and after education was provided. Methods: In the primary inspection, a status survey checklist was completed by visual inspection. A questionnaire on the awareness of proper vaccine storage and handling was also administered to vaccine administrators in private medical institutions in 4 regions in Gyeongsangbuk-province. One-on-one education was then carried out, and our self-produced manual on safe vaccine storage and management methods was provided. In the secondary inspection, the investigators visited the same medical institutions and used the same questionnaire and checklist used during the primary inspection. The results before and after education were compared, by treating each appropriate answer as 1 point. Results: The average checklists score was 9.74 (out of 15 points), which increased significantly after education was provided (by 0.84, p<0.001). The participants demonstrated improved practices in recording storage temperatures(p=0.016), storing vaccines in the center of the refrigerator (p=0.004), storing vaccines with other medication and nonmedical items (p=0.031) after education. The average score calculated from the questionnaires was 10.48 (out of 14points), which increased after education (by 1.03, p<0.001). Conclusions: This study suggests that vaccine storage practices and awareness are inadequate, but can be partially improved by providing relevant education. Repetitive education and policy-making are required to store vaccines safely because one-off education and unenforced guidelines offer limited efficacy.

Due to the bitter competition in markets and the need changes of consumers, customer relationship management(CRM) plays a key role in determining management strategies in companies. In addition, due to the advance of Ubiquitous environment, new applications are developed in the CRM arena. Since traditional data gathering methods can invade people's privacy and cause inaccurate data, new methods are required. In this paper, we propose an RFID-based automatic analytical information generation system for a ubiquitous CRM. Firstly, we develop an RFID middleware. And then, we store the data acquired from the middleware into a database. Finally, we analyze the data automatically and convert the data into meaningful information. By applying our system to an exhibition hall, automatically generated analytical information are given to companies and customers. The proposed system can make many companies meet their customers' needs in a ubiquitous way and can give them more accurate data by using clustering, associating, sequencing when they make a decision for their successful marketing.

The purpose of this research paper is to develop Mobile application-based Nursing Process Programs on 'Nursing Diagnosis', 'Nursing Interventions' and 'Nursing Outcomes Classification' targeting nurses and nurse students. To achieve it, this paper uses 'standard classification-focused research data' on the basis of Nursing Diagnosis Classification established by NANDA (North American Nursing Diagnosis Association), NIC (Nursing Interventions Classification) and NOC (Nursing Outcomes Classification) mainly developed by Iowa State University. The existing research methods are difficult to be applied to patients, since such methods put a restriction on choosing, developing, and generalizing 'Nursing Process Programs' in clinical spheres. But, this research thesis focuses on developing guidelines applicable to any clinical experiences, with the use of the framework in mutual links with all the nursing diagnosisoutcomes- interventions. In this regard, the Korean version programs were developed and registered in App store in March. Thus, it is expected that these programs would be wildly-available as tools for nursing education.

Data Mining is widely used to discover knowledge in many fields. Although there are many methods to discover association rule, most of them are based on frequency-based approaches. Therefore it is not appropriate for stream environment. Because the stream environment has a property that event data are generated continuously. it is expensive to store all data. In this paper, we propose a new method to discover association rules based on stream environment. Our new method is using a variable window for extracting data items. Variable windows have variable size according to the gap of same target event. Our method extracts data using COBJ(Count object) calculation method. FPMDSTN(Frequent pattern Mining over Data Stream using Terminal Node) discovers association rules from the extracted data items. Through experiment, our method is more efficient to apply stream environment than conventional methods.

The purpose of this study was to examine the extent of purchase of processed foods and the awareness about food label among middle school students. This survey was conducted by involving 350 middle school students in Incheon city, Korea from June 17~19, 2015. Middle school students consumed confectioneries, bread, carbonated drinks, and juices and ice creams once or twice a week at the rate of 53.4, 53.0, 40.6, and 36.9%, respectively. The most frequent place, time, and reason to purchase the processed foods were 'convenience store (36.2%)', 'after school (26.8%)', and 'hunger (77.9%)'. The subjects exhibited top priority (57.0%) on the taste at the time of purchasing the processed foods. Interestingly, the girl-students (44.7%) checked the labels of food more than the boy students (34.0%). The reasons for checking the food labels included acquiring significant information about the shelf life (27.0%), price (18.1%), nutrient (19.1%), and food additives (14.1%). Among the food labeling information, the name of the product (55.7%), the date of manufacture (49.3%) and the content (32.6%) were checked mainly by the subjects. In addition, the major reason for not confirming the food labeling was 'the food label was too small or crude (31.9%)'. It is necessary to inform about the processing methods and ingredients of the processed to middle school students so that they can make the correct choice of processed foods. Development of proper education methods on nutrition for middle school students is necessitated for healthy living.

This study was to propose a basic model of specialization in home economics for vocational high school development in JellaNamdo. The results were summarized as follows. First. based on the changes in economic environment into service industry and national educational policy and local vocational educational Policy, it may be good time to socially discuss special vocational high school in home economics in JellaNamdo in the light of meeting local students' demand. Secondly, considering local students' preference and the conditions of local economy and industry. Thirdly, the system for specialization in home economics of vacational high school may be suggested. The basic model was organized plans of system reformation by stages, a substantial plans, and academic or employment course development. System reformation plans was that the high school-concentrated district should be first selected by area and department and one high school should be selected as special high school in home economics. Then specific method should proceed school name, the measure to recruit students, specific method for reorganizing department. and curriculum. Finally, the annual plan to establish new department and to recruit students should be Prepared. Substantial plans were to actually forward such methods to reorganize system and to enhance the qualify of vocational high school education. the method for making substantial should be studied further It may include: the methods to ensure special teachers, training room, and facilities. the prospect and direction of career development, employment, or initiation, special research, and the application to educational environment. Employment courses were developed SOHO establishment in small capital and special store management. And academic courses was to enter a collage or university in conjunction with major departments.

Solving a system of linear or non-linear equations is required to analyze any kind of structures. There are many ways to solve a system of equations, and they can be classified as implicit and explicit techniques. The explicit methods eliminate round-off errors and use less memory. The dynamic relaxation method (DR) is one of the powerful and simple explicit processes. The important point is that the DR does not require to store the global stiffness matrix, for which it just uses the residual loads vector. In this paper, a new approach to the DR method is expressed. In this approach, the damping, mass and time steps are similar to those of the traditional method of dynamic relaxation. The difference of this proposed method is focused on the method of calculating the damping. The proposed method is expressed such that the time step is constant, damping is equal to zero except in steps with maximum energy and the concentrated damping can be applied to minimize the energy of system in this step. In this condition, the calculation of damping in all steps is not required. Then the volume of computation is reduced. The DR method for form-finding of membrane structures is employed in this paper. The form-finding of the three plans related to the membrane structures with different loading is considered to investigate the efficiency of the proposed method. The numerical results show that the convergence rate based on the proposed method increases in all cases than other methods.

Since a migration method of the mobile agent is a factor that affects the overall performance of the entire distributed system, it is necessary to find efficient migration methods of the mobile agent within the sensor network and to collect and store data related to various components(server, sink and sensor node) of the sensor network, thereby providing consistent naming services. Accordingly, this paper presents design and implementation of MetaTable that is divided into MetaData where information on the sensor data server is stored and SubMetaData where various types of information on sink nodes and data on sensor nodes connected with the sink nodes is stored. Moreover, the paper also presented the implementation of forward migration of an active rule mobile agent applying the naming method based on RMI that used the meta_table and proposed the possibility of constructing efficient sensor network application environment. In this paper, for registration, release and retrieval methods suitable for new sensor network environment, we designed and implemented the naming agent by applying J2EE model based on RMI-IIOP(Internet Inter-ORB Protocol) technique.

Lots of application systems are developed for applying business GIS in marketing or strategic planning of the company, recently. Almost of the systems require statistics for some areas(trade areas or sales areas) as the important information of decision support. As far as now, trade areas are defined for individual stores using know-how of the specialists, but there is no well-defined method for defining of trade areas of the specific business domains or trade areas of the customers. In this study, we have applied the spatial data mining methods to the point features in GIS, evaluated the results of each methods, and discussed the feasibility of defining of trade areas. From the results of this study, we have concluded that the defining of trade areas from point features, such as franchisees of credit card company or memberships of retail chain store, and that the DENCLUE(DENsity-based CLUstEring) method is the best suitable spatial data mining algorithm for this purpose.

Nowadays, space branding becomes more important since it reflects and synthesizes the diverse experiences of the consumer. The objective of the research is to present the new possibilities that space branding offers by analyzing the brand strategy and the design characteristics of branded hotels, which are being projected as constructed branded environments. By integrating the brand with visible or invisible elements of the hotel, such as unique space planning, service, and consumer experience, a branded hotel can be a good vehicle to reflect fast changing consumer lifestyles and trends; it enables the consumer to experience brands in his or her everyday life, and it conveys the overall image of the brand by considering the consumer's multi-sensual experiences. The study processed with theoretical research which is related to the hotel space and branded environment. Four brands were selected with distinct business area and brand strategy, and studied to analyze the strategy and the characteristics of the branded environment in a branded hotel. In particular, the case study attempted to evaluate the distinctiveness of the branded hotel's spatial design by comparing each brand's representative flagship store with the hotel. As a result, four characteristics of branded environments in branded hotels were identified, namely, strengthen brand image, consistent brand strategy, extend brand perception, spatialize brand experience. Armani emphasizes their consistent brand image by applying similar design methods in both retail stores and hotel spaces. IKEA, in contrast, applies not their design identity but their brand concepts like practicality, efficiency, and low prices. Pantone gives an expanded brand experience by using synesthetic sensual stimulation using their color system. Missoni mixes and composes their patterns and materials in a three-dimensional manner and strengthens design possibilities and spatiality. This study suggests specific design methods to construct a branded environment in a branded hotel and offers new strategic directions for space branding.
