  • In general, user requirements in web-based learning systems are divided into functional and non-functional requirements. Developers are responsible for the verification of quality related requirements, which is known to be difficult to perform. This paper suggests a verification method that can be applied in the area where the conformance of implementation for non-functional requirements is required. The paper performs tests for non-functional requirements by using the information extracted from quality related features that have imposed constraints on design activities.

  • This study proposes proportions of functional areas in the ward of general hospitals, which are derived from 5 big university hospitals in order to establish the ward area standard for hospital design. The results of this paper are as follows. First, functional areas of hospital ward are composed of bedroom area, nursing area, training area, service area, and common area. Of course common area can be divided into first common area and secondary common area. The first common area(inter departmental common area) includes lobbies, elevator lobbies, corridors, restroom, and mechanical shafts. The secondary common area means the common area within special department such as ward or radiology department. Second, a standard method of calculating ward areas has been proposed: the standard is based on the center line of the wall between functional areas. Third, the proportions of 6 functional areas in ward are suggested.

  • The rapid growth of complexity and scale can be witnessed in the design and development of modern systems. As such, the severity of damages in the occasional accidents has attracted great deal of attention lately. Although a variety of methods have so far been studied to overcome or reduce the disastrous results of hazards, the issues seem still persistent and even complicated due to the situation mentioned above. The concept of functional safety has been regarded as one approach to handling the matters by shifting up to the functions level from the consideration of each physical component itself. The outcomes of those efforts would be the international standards on functional safety such as IEC 61508 and its relatives including IEC 62278, EN 50128, ISO26262, and so on. In this paper, a method of how hazards can be analyzed to be coped with those standards has been studied. In the method proposed, the systems modeling language (SysML) is playing a key role to model and analyze the hazards from the viewpoint of functional safety. The approach taken has been applied in the analysis of the hazards in railroad systems. In spite of focusing on the individual components hazards, the method based on functional safety has analyzed them collectively with the added effect of identifying the cause originated from the interface between the functions.

  • Objective: Setting therapeutic goals assist to identify patient priorities and predict problem that may arise in performing daily and functional activities. Goal setting is associated with improved rehabilitation outcomes in individuals with hemiparetic stroke. This study was conducted to assess the effects of having awareness and satisfaction of goals on the functional status of individuals with hemiparetic stroke. Design: Cross-sectional study. Methods: Eighty-one people who had been diagnosed with stroke participated in this study. The study was conducted through a face-to-face surveys to identify participants' awareness and satisfaction of goals and standard assessment tools were used to evaluate patients' functional status. This study measured functional status through three clinical measures including the manual function test (MFT), Berg Balance scale (BBS), and modified Barthel index (MBI). Results: In participants with hemiparetic stroke, the MBI, BBS, and MFT scores were significantly higher in the participants who were aware of the therapeutic goal than in those who were unaware (p<0.05). The MBI, BBS, and MFT scores were not significant between the participants who were satisfied with the goal and those who were unsatisfied. Conclusions: This study suggests that having awareness in therapeutic goal-setting could lead to improvement of functional status in those with hemiparetic stroke. This study highlights how goal-setting can have a positive effect on persons with hemiparetic stroke.

  • Increasing knowledge on the link between diet and human health has generated a lot of interest in the development of functional foods. However, several challenges, including discovering of beneficial compounds, establishing optimal intake levels, and developing adequate food delivering matrix and product formulations, need to be addressed. A number of new processes and materials derived from nanotechnology have the potential to provide new solutions in many of these fronts. Nanotechnology is concerned with the manipulation of materials at the atomic and molecular scales to create structures that are less than 100 nm in size in one dimension. By carefully choosing the molecular components, it seems possible to design particles with different surface properties. Several food-based nanodelivery vehicles, such as protein-polysaccharide coacervates, multiple emulsions, liposomes and cochleates have been developed on a laboratory scale, but there have been very limited applications in real food systems. There are also public concerns about potential negative effects of nanotechnology-based delivery systems on human health. This paper provides an overview of the new opportunities and challenges for nanotechnology-based systems in future functional food development.

  • Purpose: The purpose of this study was to explore factors that influence care dependency of institutionalized patients with dementia. Method: This study utilized descriptive correlational design. The convenience sample was composed of 110 residents with dementia of two long-term care facilities in Korea. Stepwise multiple regression was used to identify significant factors influencing care dependency in patients with dementia. Care dependency was measured using the Care Dependency Scale, Korean version(CDS-K). Cognition was measured by the MMSE-K. Functional disability was measured by the PULSES Profile. Behavioral dysfunction was measured by the modified E-BEHAVE AD. Result: Care dependency was significantly influenced by cognition, functional disability, behavioral dysfunction, and duration of dementia. This regression model explained 61 % of the variances in care dependency. Cognition explained 37% of the variances, and functional disability explained 21% of the variances. Conclusion: Results of this study suggest that professional caregivers intervene more effectively in caring for their patients with dementia by recognizing the patients cognitive, functional, behavioral disability, and its periodic change. Individually, remaining abilities-focused intervention should be applied to enhance patient to be dependent and to prevent unnecessary independency.

  • The use of electricity to evoke s skeletal muscle response is FES, which is a form of functional electrical stimulation. In the case of the damaged spinal cord, the technique can supply stimulation to the lower moter neurons and their muscle fiber, which have been disconnected from control of the higher nervous system. Recent advances in electronics, particularly miniaturization, have made possible the design of much improved systems of electrodes and stimulaters for FES. Clinical research has followed two main lines: the use of FES in the upper extremities for producing functional hand rehabilitation in quadriplegics and in the lower extremities for producing standing and gait in paraplegics.

  • In this paper, we consider a service system with bi-functional servers, which can switch between the primary service room and the secondary room. A service policy is characterized by the switching paints which depend on the queue length in the primary service room and the service level requirement constraint of the secondary room. The primary service room is modeled as a Markovian queueing system and the throughput of the primary service room is function of the total number of bi-functional servers. the buffer capacity of the primary service room, and the service policy. There is a revenue obtained from throughput and costs due to servers and buffers. We study the problem of simuitaneously determining the optimal number of servers, buffer capacity, and service policy to maximize profit of the service system, and develop an algorithm which can be successfully applied with the small number of computations.
