Purpose: The purpose of this study was to investigate the academic achievements, satisfaction and educational demands of nursing students at a college of nursing. Methods: The study subjects consisted of 134 senior nursing students who completed their clinical practicums. The students were asked to complete the evaluation survey for the curriculum. The evaluation survey for the curriculum consisted of three parts: 1) academic achievements of educational objectives, care of subjects, and skills; 2) satisfaction with the curriculum, clinical practice environment, and educational environment; 3) demands on the curriculum and clinical practicum. Results: The mean scores on the achievement levels of educational objectives, care of subjects and skills of the students were $3.68{\pm}0.53$, $3.69{\pm}0.59$, and $3.77{\pm}0.56$, respectively. The low rated domains were 'understanding and delivering culturally competent nursing' and 'competence in fundamental nursing skills' in their levels of achievements. Overall, students were satisfied with the nursing curriculum and educational environment. However, their satisfaction scores for the hours and arrangements of the clinical practicum, and the ratios and arrangements of lectures and clinical practicum were relatively low. Conclusion: The findings of this study are important to redesign nursing curriculum in order to prepare graduates for rapidly changing health care environments. We need to try various strategies to improve the clinical competencies of students by designing a curriculum based on social change and student needs.

The delay times due to the propagating of data on PCB depend on the shape and length of interconnection lines when memory controllers and high speed memories are soldered on the PCB. The dependency on the placement and routing on the PCB requires redesign of I/O logic or reconfiguration of the memory controller after the delay time is measured if the controller is programmable. In this paper, we propose architecture of configuring logic for the delay time estimation by writing and reading test patterns while initializing the memories. The configuration logic writes test patterns to the memory and reads them by changing timing until the correct patterns are read. The timing information is stored and the configuration logic configures the memory controller at the end of initialization. The proposed method enables easy design of systems using PCB by solving the problem of the mismatching caused by the variation of placement and routing of components including memories and memory controllers. The proposed method can be applied to high speed SRAM, DRAM, and flash memory.

This work proposes an optimality criteria applicable to the optimum design of plane frames subject to multiple behavioral constraints on member stresses and lateral displacements of nodes and also to side constraints on design variables. The method makes use of a first order approximation for both deflection and stress constraints instead of the zero order approximation based on the concept of FSD (fully stressed design). A redesign algorithm is derived from a mathematically rigorous method which uses the Newton-Raphson method to solve the system of nonlinear constraint equations and reduces the design space whenever minimum size restrictions become active. When applied to worked examples it proved more accurate and efficient, and it is often found that optimum designs are not fully stressed designs. This fact suggests that this rigorous method is worth what it claims for complicated computing and thus had better replace the crude stress ratio algorithm adopted by the majority of optimality criteria approaches. This is particularly true as long as we enjoy ever-increasing computing power at negligible costs.

Today, current society is unceasingly changing. This phenomenon accelerate building to high-rise and complex. According to that, to build a construction structure, the safety management facilities, safety education & training for employee and consciousness for safety should be set aside. But, the occurrence of safety injury is not decreasing now. Therefore, to reduce safety injury and to enhance the consciousness of employee for safety, redesign of safety management system, reallocation of safety liability for privity, revise of safety educational system were suggested in this paper.

Recently, due to the popularity of object-oriented programming languages, object-oriented modeling and development methodologies become widely applied to information system development. When object-oriented methodology is adopted, using object-oriented modeling languages for business analysis and redesign has the advantages such that business modeling results can be easily understood and referred by information system developers. In this paper, UML-B, Unified Modeling Language extension for Business modeling is proposed, which uses UML notation for modeling organization structure, actors, use cases, business processes, and entities in business systems. It also utilizes extension mechanisms of UML to facilitate business modeling activities, and supports business process reengineering with object-oriented modeling.

Songjung beach located in Busan has been developed without design concept or any specific plans for its characteristics. This study attempts to suggest design ideas with specific plans and 3D perspectives in order to develop Songjung beach based on the characteristics and needs of the visitors and provide its own identity. The research was performed in three steps: First, the researcher visited the beach and explored how the beach facilities were used. Second, the satisfaction level and needs on the beach were investigated by questionnaire. Third, the specific plans were suggested based on the above results, which included 5 poly units with restroom, shower room, snack bar, fast-food restaurant, internet Cafe and cafeteria, etc. The form and color of the poly units were decided to show Korean traditional roof image and provide unique image to Songjung beach. This study will show a good example of beach design project reflecting visitors' specific needs through the research.

The dam made reservoir, a major means to overcome the problems caused by water resource's uneven supply by time and space, plays an important role, particularly, of water supply. The role of water supply will get more important, considering the usage of water resource becomes more intensive. Therefore, it is continuously required to construct new dams securing water supply and to study on effective operation plans of the dam. The size of reservoir needs to be measured according to possible supply estimation in the pre-design stage. The depth of water, at this point, should be taken. Among many ways of sounding, echo sounding has been frequently used recently. This study, therefore, presents a new way of sounding that takes less time with stronger accuracy, uniting GPS and echo sounder to apply a means of obtaining three dimensional position data. This enables the designer to escape from the conventional way of sounding in the estimation of reservoir to design and redesign a new dam.

The importance of prediction is becoming more emphasized, due to the uncertain business environment. In order to implement the predictive model, a number of data engineers and scientists are involved in the project and various prediction ideas are suggested to enhance the model. it takes a long time to validate the model's accuracy. Also It's hard to redesign and develop the code. In this study, development method such as Lego is suggested to find the most efficient idea to integrate various prediction methodologies into one model. This development methodology is possible by setting the same data layout for the development code for each idea. Therefore, it can be validated by each idea and it is easy to add and delete ideas as it is developed in Lego form, which can shorten the entire development process time. Finally, result of test is shown to confirm whether the proposed method is easy to add and delete ideas.
