Fast curve generation is one of important techniques which facilitate fast process of computer graphics applications. It is possible to resolve the task through hardware or software. But rapid development of computer graphics area need methods for more fast generation of curves. This paper propose a algorithm (called CDAUD), which computes the coordinates of points on curve only with add operations using for ward differences and draw the curve fast. It also contains the method for generation of smooth and fully connected curves. Time complexity of CDAUD shows that it is superior than the existing method for constrained case, and it's superiority was validated through experimental implementation.

All Korean professional engineer′s great joy Is to welcome the Japanese professional engineers and relevant guests to the 1987 Japan-Korea Professional Engineers Joint Convention organized by the Korean Professional Engineers Association. As there exists an effort of blood, sweat and tear behind a succeeded theatrical stage, so an exquisite devotion with drawing up a master plan, investigation, supervision and etc by engineering firms is soaked through every part of huge construction projects and large unit factory buildings. It is over 14 years that the Engineering Service Promotion Law has been enacted by the Ministry of Science and Technology. In the meantime, the domestic engineering (engineering service) have reached a remarkable higher level while the number of engineering firms participating in overseas market has gradually been increasing. From a small scale of under water investigation to a large scale planning of atomic reactor or petrochemical plant, engineering service business can be said "The Software of Total Industry." Engineering service is what is called a higher business which offers specialized engineering know-how and experience. Engineering service compaines offer Its specialized knowledge and experience to government, industry and commerce. Whether the task is to modernize plant equipment, to design a building or to manage construction, an engineering company will develop and implement the most appropriate and cost effective solution. Clients use the engineering service of firm knowing that the engineer′s professional judgement is not influenced or biased by other commercial affiliations. While benefiting from the diverse experience that professional engineers can apply to a specific problem, government and industry also reduce the need for permanent in-house engineering staff. Engineering firms may be specialized or multi-disciplinary.

This research focuses on the cadastre and cartographic tradition regarding the representation of Rome that had lasted until the middle of 18th Century. Since the early period of Roman Republic until the early 18th Century, map was considered as a effective medium to record the status of urban facts and also a manifestation of changing perception of reality. These facts allow to diagnose social and conventional changes that had occurred in the field of representation techniques and methodologies derived from diverse intention and objective in elaboration of each map. Cartography also has affinity to architectural drawing as many categories of individuals are involved, clients, researchers, craftsmen, publisher and collectors. Fundamental task of documenting the contemporary physical reality was given to the map, however, as architects had practiced through the drawings, cartographers also reconstruct in subjective way specific buildings and urban aspects according to various needs and demands. As such, philology and imagination play important role as two constitute extreme poles in the evolution of the cadastre. Through analysis of paradigmatic examples in the genealogy of cartography of Rome, it was possible to understand the changing episteme that testify the mentality and custom in the field of visual representation.

Purpose: The ward division is a representative part of the hospital, where a variety of user activities are performed. Users can be broadly categorized as patients and carers, visitors, and medical staff (doctors and nurses). The relationship between these two is a major issue with ward planning as the patient's place of life centers around the hospital room and the task of the clinical workforce centers around the nursing station (NS). Against this backdrop, the study divides the ward units of the General Hospital of China into patient areas, medical team areas, supply areas, and public domain, with the focus on the ward areas affecting most significantly in the hospital patients. Methods: The theoretical advance studies of the standard ward unit are identified by the associated guidelines, articles, and documentation. Results: This study is a summary analysis of relevant regulations, reference literature, and drawing data from the target hospital. Further work is expected to be undertaken, including further surveys and observational surveys, to produce more detailed results. Implications: It is expected that the research in this paper will provide an effective reference for the future research of China General Hospital Ward department, so as to promote and improve the work system of China General Hospital Ward department.

There has been an explosion of new research and writing about all aspects of the information disciplines. Nevertheless, both academics and practitioners often find it difficult to engage in successful writing strategies. Indeed, writing is hard work, and doing it in a way that leads to publication is an even harder task. Since reading is essential to good writing, the challenges of learning to write are obvious. In this essay, I am drawing on many years of experience in writing and publishing, as well as considerable reading of writers’ memoirs, advice books on writing, literary studies, and other perspectives on the experience of writing in order to offer a set of approaches that can be pursued over a lifetime of scholarship and practice. Writing is a craft or art to be learned, and learning demands paying attention to the audience, having clear objectives, being an avid reader, and possessing the ability to accept and learn from criticism. While information professionals and scholars incessantly write for each other, there are large segments of the public and other disciplines who they ignore. Fortunately, the tools and resources for improving one’s writing are both broad and deep; discipline and realistic strategies are all that are required to improve one’s writing and, ultimately, to achieve success in publishing.

Nowadays computer technology is being applied in various areas of apparel design. In particular, since the task of pattern making is to be performed by a set of predefined drawing rules, the effect of computer application in pattern making will be significant, There have been a large number of studies on pattern making program. For instance, the previous studies have developed computer programs for pattern making of women's wear, men's wear, children's wear, Han-Bok, etc. Most of them have focused on the development of computer program for a particular kind of apparel only and, however, have disregarded the feasibility of developing a multi-purposed computer program so that is just can be modified to adopt for various styles. For example, by widening the hem-wide of the basic H-Line skirt and then connecting its waist line and widened hem-wide, we can draw the A-Line skirt. Therefore, we have developed a program which can make a pattern for the basic skirt and can mae, with a slight change of he program, other patterns for various style as well. The objective of this paper is to identify and organize modules which will be used for developing a general pattern making computer system. This general pattern making system is a computer program by which we can draw a variety of apparel styles. This system is restricted to skirt pattern making only. there presentation scheme used in organizing these modules is an AND-OR tree, the one being often used in representing a complex problem in artificial intelligence domain.

Purpose: Do close linkages among employees during service encounters always enhance customer satisfaction? Drawing on literature in social psychology, this research argues that under certain circumstances close linkages among employees undermine customer satisfaction. More specifically, this research explores a service failure context and shows that higher task interaction among employees during service encounters leads to higher perceived firm entitativity, resulting in an individual employee's service failure being detrimental to customer satisfaction with the firm. Data and research methodology: A series of experiments using scenarios across different service contexts was used in order to test hypotheses. Data was collected via Amazon Mechanical Turk and the models were tested using Hayes PROCESS. Results: The results show that interactions among employees during service result in 1) lower satisfaction with the firm and 2) lower revisit intentions in the future when there is a service failure by an individual employee. Following the main effects analysis, mediation analysis shows that the effect of employee interaction on customer satisfaction with the firm and revisit intention is mediated by perceived firm entitativity. Implications: By examining contexts where employee interaction may be detrimental to firms, this research provides novel insights on how to manage communications among service employees.

In architecture, each project participant must maintain organic relationship with others. However, current practices are rather procedural and discrete than organic, which result in considerable inefficiencies. The cool-downs of Korean construction market also force the architects to be familiar with the new construction methods and systems. This research mainly focuses on the pre-development stage of such systems, analysing relationships between the information of architectural design and other parts of construction information like structure, construction, environment, and so forth. The result of analysis can be organized into attributes of members in a physical building, which can be modeled in a 3D system. The resulting model can be used for automated generation of drawing, Bill of Materials, finite element meshes for structural analysis and energy analysis, etc. by extracting meaningful information from it. Hence, the purpose of this research is to analysis the relationship among domain-specific information (e.g. structural engineering, construction detail, energy evaluation) that are represented in drawings, and to represent the attributes of the information relevantly so that they can be applied to each unit task that forms the whole project. Therefore, an object oriented methodology is introduced to compose design informations in three dimension, and expressing properties of building factors and materials, and to construct a database for computers to recognize architecture informations.

The safety of nuclear power plants is analyzed by a probabilistic risk assessment, and the fault tree analysis is the most widely used method for a risk assessment with the event tree analysis. One of the well-known disadvantages of the fault tree is that drawing a fault tree for a complex system is a very cumbersome task. Thus, several graphical modeling methods have been proposed for the convenient and intuitive modeling of complex systems. In this paper, the reliability graph with general gates (RGGG) method, one of the intuitive graphical modeling methods based on Bayesian networks, is improved for the reliability analyses of dynamic systems that have various operation modes with time. A reliability matrix is proposed and it is explained how to utilize the reliability matrix in the RGGG for various cases of operation mode changes. The proposed RGGG with a reliability matrix provides a convenient and intuitive modeling of various operation modes of complex systems, and can also be utilized with dynamic nodes that analyze the failure sequences of subcomponents. The combinatorial use of a reliability matrix with dynamic nodes is illustrated through an application to a shutdown cooling system in a nuclear power plant.
