  • 최근 간호교육의 질적 향상을 위한 노력이 지속되고 있으며, 디지털 기술의 활용에 대한 관심이 높아지고 있다. 간호실습교육 분야에서도 디지털 기술의 활용이 강조되고 있는데, 이는 학습자들에게 보다 효과적이고 접근성이 용이한 교육 경험을 제공할 수 있을 뿐 아니라 개별학습자의 학습성과를 통합적으로 관리할 수 있다는 잠재력을 지니고 있다. 본 연구는 이러한 전망을 바탕으로 디지털 간호실습교육 플랫폼을 개발, 교수자와 학습자들이 실습교육에 필요한 교육 내용과 콘텐츠의 특성에 따라 기능을 선택할 수 있도록 하였다. 또한 UI는 학습자가 주어진 과업과 과제에 대한 정확한 이해와 수행을 돕도록 디자인되었다. 본 연구에서는 플랫폼의 설계 및 구현 과정을 상세히 기술하고, 10명의 각기 다른 실습 교과목을 담당하는 교수자의 피드백을 바탕으로 플랫폼의 유용성을 검증하였다. 디지털 간호실습교육 플랫폼의 높은 사용성이 확인되었고, 학습자들의 학습 효과 향상에 유의미한 영향에 대한 가능성을 확인할 수 있었다. 이러한 디지털 플랫폼은 향후 간호교육의 혁신적인 전환을 이끌어 낼 수 있을 것으로 기대된다.

  • The Aerial platform Truck is widely used for work in high place with the aerial platform. The most important thing is that worker's safety and worker must be able to work with trustworthiness so it needs to be verified its stiffness, deflection of boom, and dynamic condition concerned with a rollover accident. It should have an analytical exactitude because it is directly linked with the worker safety. In this point, we are trying to develop a proper CAE analysis model concerned with a rollover safety, bending stress and deflection for load. The Aerial platform Truck have a dynamic characteristics by load and moving of boom in the work field, so its static and dynamic strength analysis, structural mechanics are very important. Therefore, we evaluate the safety of each boom to calculating its stress, deflection. A computer simulation program is used widely for doing applying calculation of stiffness and structural mechanics, then finally trying to find a optimum design of the Aerial platform Truck.

  • This paper describes the design of an asynchronous implementation of a sensor network processor. The main purpose of this work is the reduction of power consumption in sensor network node processors and the research presented here tries to explore the suitability of asynchronous circuits for this purpose. The Handshake Solutions toolkit is used to implement an asynchronous version of a sensor processor. The design is made compact, trading area and leakage power savings with dynamic power costs, targeting the typical sparse operating characteristics of sensor node processors. It is then compared with a synchronous version of the same processor. Both versions are then compared with existing commercial processors in terms of power consumption.

  • Length of a vehicle is an important variation to generate different variants of an automotive platform. This parameter is usually adjusted by embedding dimensional flexibility into different components of the Body in White (BIW) including the floor pan. Due to future uncertainties, it is not necessarily possible to define certain values of wheelbase for the future products of a platform. This work is performed to add flexibility into the design process of a length-variable floor pan. By means of this analysis, the cost and time consuming process of optimization is not necessary to be performed for designing the different variants of a product family. Stiffness and mass of the floor pan are two important functional requirements of this component which directly affect the occupant comfort, dynamic characteristics, fuel economy and environmental protection of the vehicle. A combination of Genetic algorithm, GMDH-type of artificial neural networks and TOPSIS methods is used to optimally design the floor pan associated with arbitrary length of the variant in the defined system range. The correlation between the optimal results shows that for a constant mass of the floor pan, the first natural frequency decreases by increasing the length of this component.

  • 창의적, 능동적인 문제해결 능력을 가진 지식노동자를 요구하는 정보화 사회에서는 교수자 중심이 아닌 학습자 중심의 온라인 교육 콘텐츠 기술의 발전이 급속히 요구되고 있다. 대부분의 온라인 학습 콘텐츠의 특성은 학습자 중심이라기보다 교수자 중심의 강의 진행, 콘텐츠 제작과 콘텐츠 제공 플랫폼의 부족한 기능들로 학습자가 중심이 되는 온라인 학습 특성을 만족시키지 못하고 있는 실정이다. 본 연구에서는 온라인 학습 특성인 학습자 중심의 온라인 교육을 위한 콘텐츠 제공 플랫폼에 대해 기존의 콘텐츠 제공 플랫폼과 상호보완적 입장에서 구성하는 방안에 대하여 제안하고자 한다.

  • This study has four objectives: (1) Identifying factors that affect customer satisfaction on online service quality of Tiki.vn, (2) Measuring the level of impact of the factors, (3) Testing the difference in satisfaction among groups of customers with different characteristics in terms of gender, age, income, academic level, and occupation, and (4) Proposing some managerial implications to improve the quality of online services by interviewing directly and online 200 individual customers who have shopped at Tiki.vn E-commerce platform for at least the last six months, using the convenient sampling method. This study analyzes the reliability of the scale through the Cronbach's alpha coefficient, Exploratory factor analysis, and Linear regression analysis. The findings identified four factors that influence positively customer satisfaction regarding the quality of online services in Tiki.vn E-commerce platform in the order of descending strength: (1) Trust, (2) Customer service, (3) Web design and (4) Safety. In addition, the results show no difference in customer satisfaction according to different academic levels, but in terms of occupation and income, gender, and age. The results show that the factors influencing most customer satisfaction are Reliability and Customer Service. Some managerial implications are then proposed to improve the quality of online shopping services at Tiki.vn.

  • In this paper, path generation using the sensor platform is proposed. The sensor platform is composed two electric motors which make panning and tilting motions. An algorithm fur a real path form and an obstacle length is realized using a scanning algorithm to rotating the sensors on the sensor platform. An ARV (Autonomous Robot Vehicle) is able to recognize the given path by adapting this algorithm. In order for the ARV to navigate the path flexibly, a kinematic model needed to be constructed. The kinematic model of the ARV was reformed around its body center through a relative velocity relationship to controllability, which derives from the nonholonomic characteristics. The optimal controller that is based on tile kinematic model is operated purposefully to track a reference vehicle's path. The path generation algorithm is composed of two parks. On e part is the generating path pattern, and the other is used to avoid an obstacle. The optimal controller is used for tracking the reference path which is generated by recognizing the path pattern. Results of simulation show that this algorithm for an ARV is sufficient for path generation by small number of sensors and for low cost controller.

  • A large number of offshore wind turbines with fixed foundations have been installed in water depths up to 30 meters supporting 3-5MW wind turbines. Some floating platform concepts of offshore wind turbines were designed to be suitable for deployment in water depths greater than 60 meters. However the optimal design of this system in water depth 50 meters remains unknown. In this paper, a 5-MW wind turbine located on a TLP type platform was suggested for installation in this water depth. It is moored by a taut mooring line. For controlling the wind turbine always be operated at the upwind direction, one yaw controlling was attached at the tower. To study motion characteristics of this platform, a model was built with a 1/128 scale ratio. The model test was carried out in various conditions, including waves, winds and rotating rotor effect in the Ocean Engineering Wide Tank of the University Of Ulsan (UOU). The characteristic motions of the TLP platform were captured and the effective RAOs were obtained.
