  • This paper presents an automated API translator for embedded software development based on a model-driven approach. Since MDA(Model Driven Architecture) provides little support for the development of embedded software, we propose a new approach containing its advantages. First, we define #generic APIs# which do not depend on any RTOS#s but provide most of typical RTOS services. We can describe RTOS-related behaviors of target application using these generic APIs in a CIC(Common Intermediate Code). Then, we propose a transformation tool for translating between a CIC using generic APIs and a C-code for specific RTOS. The proposed API translator converts them using XML transformation rule which is defined outside. It indicates that an API translator extends to other RTOS#s by modifying or adding the transformation rule. From the experiment. we validate the proposed method.

  • The aim of this study on the Munich Olympic Park is to understand the characteristics and design techniques of the environmental design of G$\ddot{u}$nther Behnisch's architecture. This particular work is chosen because it represents a turning point in his architectural life in terms of his approach to environmental design. The goal of this paper is to research Behnisch's design techniques in order to realiz a way to apply nature-friendly design in contemporary-architecture. In Behnisch's architectural works, the organic design philosophies of Hugo H$\ddot{a}$ring and Hans Scharoun are clealy echoed. The site and natural surroundings are always important in his architecture. In terms of his environmentally-friendly approach, Behnisch's architecture can be defined as one which espresses a harmony between architecture and the naturale-surroundings. In terms of the structural aspect, Behnisch's architectural forms are not imposing, but rather waiting to be discovered naturally. In terms of spatial characteristics, Behnisch's spaces are based on organic characteristics and have a strong relationship between the outside and inside. In particular, the artificial architectural landscape in the Munich Olympic Park through cable-construction connects perfectly with nature.

  • Recently, the educational community has attempted to implement the theory of multiple intelligences. In approaching multiple intelligences, teachers have applied the same structural approach which has been so successful with cooperative learning. Cooperative learning is easy to learn and implement, fun for teachers and students, and produce profoundly positive outcomes along a remarkable number of dimensions. Different structures are designed for different outcomes, including enhanced mastery of subject matter, improved thinking skills, team building, class building, development of social character and social skills, communication skills, classroom management, classroom discipline, and development of and engagement of each of the multiple intelligences. Cooperative learning is becoming an increasingly popular teaching strategy. In this study, it is aimed to clarify the application of cooperative learning in health education. Cooperative Learning in health education enhances student learning by: 1) providing a shared cognitive set of information between students, 2) motivating students to learn the material, 3) ensuring that students construct their own health knowledge, 4) providing formative feedback, 5) developing social and health group skills necessary for success outside the classroom, and 6) promoting positive interaction between members of different cultural and socio-economic groups. Cooperative Learning structures and techniques in health education are following. Flash Card, Focused Listing, Structured Problem-solving, Paired Annotations, Structured Learning Team Group Roles, Send-A-Problem, Value Line, Uncommon Commonalities, Team Expectations, Double Entry Journal, Guided Reciprocal Peer Questioning, What if. Because the purpose of health education is the practice, therefore health specialists have to guide powerful and effective teaching method The application of cooperative learning in health education may improve its effectiveness.

  • There are presently two general ways of accounting for hazardous metal creep in structural fire analyses: either we incorporate creep strains implicitly in hardening model ('implicit-creep' plasticity) or we account for creep explicitly ('explicit-creep' plasticity). The first approach is simpler and usually used for fast engineering applications, e.g., following proposals of EN 1993-1-2. Prioritizing this approach without consideration of its limitations, however, may lead to significant error. So far the possible levels of such error have been demonstrated by few researchers for individual structural elements (i.e., beams and columns). This paper, however, presents analyses also for selected beam-girder assemblies. Special numerical models are developed correspondingly and they are validated and verified. Their important novelty is that they do not only account for creep in individual members but also for creep in between-member connections. The paper finally shows that outside the declared applicability limits of the implicit-creep plasticity models, the failure times predicted by the applied alternative explicit-creep models can be as much as 40% shorter. Within the limits, however, the discrepancies might be negligible for majority of cases with the exception of about 20% discrepancies found in one analysed example.

  • In this paper, a meshfree shell adaptive procedure is developed for the applications in the sheet metal forming simulation. The meshfree shell formulation is based on the first-order shear deformable shell theory and utilizes the degenerated continuum and updated Lagrangian approach for the nonlinear analysis. For the sheet metal forming simulation, an h-type adaptivity based on the meshfree background cells is considered and a geometric error indicator is adopted. The enriched nodes in adaptivity are added to the centroids of the adaptive cells and their shape functions are computed using a first-order generalized meshfree (GMF) convex approximation. The GMF convex approximation provides a smooth and non-negative shape function that vanishes at the boundary, thus the enriched nodes have no influence outside the adapted cells and only the shape functions within the adaptive cells need to be re-computed. Based on this concept, a multi-level refinement procedure is developed which does not require the constraint equations to enforce the compatibility. With this approach the adaptive solution maintains the order of meshfree approximation with least computational cost. Two numerical examples are presented to demonstrate the performance of the proposed method in the adaptive shell analysis.

  • Maritime industry is affected by outside factors significantly due to its derivative demand characteristics. However, the supply side can not react to these changes immediately and due to this uniqueness, maritime industry repeats the boom-bust cycle. Therefore the government itself needs to operate early warning system in order to monitor the market and notice the upcoming risks by setting up a system to prepare for the situations. In this research, signal approach is used to establish early warning system. Overall leading index is composed of crisis index that is based on BDI(Baltic Dry Index) and various leading indexes such as finance, economy, shipping and the others. As a result of computing overall leading index which is early warning system in maritime through signal approach, the index showed a high correlation coefficient with actual maritime risk index by difference of 4 months. Also, the result was highly accurate with overall leading index's QPS(Quadratic Probability Score) at 0.37.

  • We reviewed 56 patients who received mandibulotomy at Yonsei medical center between 1989 and 1999. We also analysed the complications associated with mandibulotomy and its contributing factors. The complications occur in 16 patients(28.6%) and are classified into two categories; intraoperative and postperative complications. Nonunion was observed in 5 patients and osteoradionecrosis in 5. The patients who received preoperative radiation therapy were more tend to develop nonunion and osteoradionecrosis. This study suggests the benefits of mandibulotomy as a surgical approach to oral cancer: 1. Paramedian osteotomy was recommended for preservation of neurovascular bundle and ease of surgical access. 2. By using thin saw blade, reapproximation was improved with minimal bone loss. 3. osteotomy on anterior mandible which lies outside the usual portals of radiation therapy decreases the incidence of osteoradionecrosis.

  • In case with severely atrophied mandibular ridges, it may be difficult to achieve adequate retention and stability of dentures through the normal functional impression process of complete dentures. In these patients, an approach using the neutral zone raising technique may be an effective alternative. The neutral zone is defined as the area where the pressure of the tongue towards the outside of the mouth and the pressure of the cheek and lips towards the inside are balanced during the normal oral function of the muscular-nervous system. Complete dentures made through neutral zone impression not only improve retention and stability, but also provide adequate tongue space in the posterior teeth area. Additionally, food residues are reduced in the area around artificial teeth, and aesthetics are improved through appropriate facial support.

  • According to Sun Tzu's Art of War, "if you know yourself and your enemy you win hundred battles out of a hundred." This is also apply for international business field. International business negotiation will not be failed if you know counter party's behavior and understand their culture and customs. The cooperative approach is known as interest-based negotiation. Interest-based negotiation is particularly effective in a global business characterized by diversity. We often need to reach agreement with people who are different from us - culturally, ethnically, or economically. If we cannot get beyond the differences, they can create obstacles to agreement. To do this, we need to focus on the interests of the parties instead of on the parties' differences. Every culture has their own distinctive feature that the people from outside seems not understand but they must have the optimistic attitude which complies with. The purpose of this paper, from the point of view above, is to examine cultural differences that could make sure comparative advantage in business negotiation of the enterprises who eager to expand their market or to invest internationally. This paper especially shows cultural deferences among Korea, China and Japan in terms of business we must consider.

  • This is an era in which companies should realize sustainable management through business models that propose social values beyond financial benefits and solve social problems. Accordingly, the role of corporate designers should be extended to social value propositions and materializations, including corporate profit-seeking. Among the members and organizations of the company, design organization and designers have strengths in terms of humanities and creativity compared to other organizations and members. We should actively seek opportunities for corporate designers to find the context of connecting businesses and society on their own, actively seek opportunities to integrate them with corporate design, expand the role of corporate designers through creative ideas, and actively pursue sustainable and wide social career development that encompasses both inside and outside of the company. To this end, we suggested three transitions of thougths to change the perception of fixed and straight-line forms of enterprise organization, enterprise design approach and product development process so far to present useful insights through case studies, how enterprise designers can accommodate social impact through new communication and access.
