Purpose: In recent years, since 2000 many hospitals have established a master plan. However, there are some hospitals proceeding in different way from the master plan while the process of execution plan. This is because the study of master plan has been incomplete yet and there is no feedback on the master plan. Therefore, the purpose of this study is to find the reasons why differences are occurred. Methods: Comparison analysis of five hospitals which have established master plans and constructed with execution plans and Questionnaire to an architect of execution plan have been conducted. Results: This study has found three points. The first one is the change in scope of business and the change of administrator. The second one is that administrator and staff of hospital have more demands for improvement in functional area rather than public area, like lobby. The last one is to check a possibility of the solution by architectural analysis. Implications: It is necessary to determine the cause of changes from master plan and execution plan, in order to reduce the change in advance.

It requires a great deal of efforts to maintain a distributed system. What is important here is that we should be able to upgrade/maintain a distributed system without stopping the system in operation. For this, what we need is a dynamic reconfigurable framework for highly available distributed systems. In this paper, we propose objects-hot-swapping methods as a solution to our problem. These methods permit us to dynamically upgrade/expand a system without stopping the system in operation. In addition, we analyze these methods and show that an approach based on proxy is the most efficient. Furthermore, we propose two proxy-based approaches: the first one based on the static proxy provides for a fast execution time but it is difficult to implement. The second one based on the dynamic proxy provides for a slow execution time but it is easier to implement. Finally, we propose a hot swapping framework for these static and dynamic proxy.

The Pfair scheduling algorithm, which is an optimal scheduling algorithm in the hard real-time multiprocessor environments, propose the necessary and sufficient condition for the schedulability and is based on the fixed quantum size. Recently, several methods that determine the optimal quantum size dynamically were proposed in the mode change environments. But these methods considered only the case in which the period of a task is increased or decreased. In this paper, we also consider the case in which the execution time of a task is increased or decreased, and propose new methods that determine the optimal quantum size dynamically.

Multithreading is attractive in that it can tolerate memory latency and synchronization by effectively overlapping communication with computation. While several compiler techniques have been developed to produce multithreaded codes from functional languages programs, there still remains a lot of works to implement loops effectively. Executing lops in a style of multithreading usually causes some overheads, which can reduce severely the effect of multirheading. This paper suggests several methods in terms of architectures or compilers which can optimize loop execution by multithreading. We then simulate and analyze them for the matrix multiplication program.

Since a government design department office was set up in 2007, active design projects have been implemented. With this opportunity, each local self-governing organization has improved its administration and institutions, and are planning intensive research on public design for efficient execution of public design projects. However, recent public design projects have caused many problems due to unspecialized design processes, a lack of cooperation with relevant organizations, and unsatisfactory management systems after projects. Therefore, to overcome such problems in the execution of public design projects, a procedure-centered model should be developed. This study aims to analyse the process structures for the strategic execution of public design projects, and the methods and content of the execution process. For this purpose, this study looked into the process structures of public design projects based on design management strategies in order to draw suggestions needed for the execution process through advanced cases. The study is summed up as follows: First, when the process of public design projects was examined in terms of management strategies and design management strategies, it included two dimensions: the management structure of general projects and the design of development projects. Secondly, through the analysis of public design cases, this study discovered useful methodologies and the main programs used and drew suggestions needed for each step in public design projects. It is expected that the results of this study will be helpful for the development of a process model appropriate for national public design projects based on the current status of the project execution and to make a contribution to systematic development in national public design.

Pyramid fusion usually adjusts the Laplacian weights of pixels of the input images by evaluating predefined criteria. This has advantages that it can selectively express intense color and enhance the contrast when applied to HDR exposure fusion. But it may cause noise because the weights are determined by pixel importance without considering the interdependent pixel relationship that constitutes a scene. This paper proposes a fusion method using simple weight criteria generated from the gray pixel values, which is expected to preserve the interdependent relationship and improve execution speed. In order to evaluate the performance of the proposed method we examine a homogeneity measure, H and compare the execution time for both methods. The proposed method is found to be more advantageous with respect to homogeneity and execution speed.

Purpose: The purpose of this study was to identify factors influencing in intention and execution of blood donation among nursing college students. Methods: A total of 241 nursing students in D city participated in this cross-sectional study. Participants completed a questionnaire regarding intention, execution, knowledge, and motivation of and attitude toward blood donation. Data were analyzed with t-tests, $x^2$ test, Pearson correlation coefficients, and linear and logistic regression. Results: There were significant correlations among intention and motivation of blood donation attitudes toward donation, and altruism. The results of regression analyses, intention of blood donation ($R^2=.14$) was significantly associated with motivation. In addition, execution of blood donation was significantly associated with knowledge (Odds Ratio [OR]=2.24, 95% CI 1.13~4.44, p=.021), motivation (OR=2.25, 95% CI 1.03~4.88, p=.041), and intention (OR=2.41, 95% CI 1.20~4.84, p=.013) of blood donation. Conclusion: Therefore, the knowledge, motivation, and intention of blood donation should be considered to encourage blood donation programs for college students.

Arduino is used in various places such as education, experimentation, and industry. Due to the easy accessibility of Arduino, it is often used by non-majors, and it is also used in media art and toy programs. Although Arduino is relatively easy to use compared to other devices, it is not easy to control various IoT components at the same time. Some tasks run independently of other tasks, while others run dependently. In this paper, I proposed the Arduino Task Framework to efficiently execute many tasks in these various situations. The design framework of this paper is largely composed of two types: synchronous execution and asynchronous execution. These two execution methods can be combined to create several independent and dependent execution routines. Asynchronous tasks are independently executed tasks and are managed by AsyncTaskGroup, while synchronous tasks are dependently executed tasks and are managed by SyncTaskGroup. AsyncTaskGroup instance and SyncTaskGroup instance are instances of the same Task and can be used in combination with another task. The Arduino framework proposed in this paper simplifies the program structure and can easily compose various tasks.

The purpose of this study is to explore factors influencing them and properties of exercise behaviors among rural elderly in Korea. To implementing it, data were gathered from a total of 356 elderly aged 65 and over living at the Seniors Well-being Villages being developed by the Rural Development Administration in Korea, using the structured questionnaires. also, data were analyzed by the SPSS / windows program. Results show that the exercise behavior of rural elderly was medium level as the average of 3.06 score($1{\sim}5$ score) and 44.2 percent among them didn't exercise regularly and 66.8% didn't participate in sports groups. Second, there were the difference in exercise behavior according to sex and age. Specifically, elderly men exercised more regularly and were aware of proper exercise methods than elderly women. However, there were no difference in exercise behavior according to age. Third, when we analyzed the difference in exercise behavior with the regularity of execution, the elderly who exercise regularly showed higher preference, awareness of necessity, regularity of execution, execution of stretching, participation in sports gatherings and awareness of proper methods than the counterparts. Fourth, we found that unhealthy elderly were more aware of necessity of exercise, exercised regularly, and participated in sports groups frequently than healthy elderly. Also, there was a positive influence of regularity of execution on exercise behavior. These results suggested that regular exercising is very important in health of rural elderly. Therefore, to improve their health, above all, exercise program must be developed
