The purpose of this study is to develop the playground environment model for child care center by analyzing user needs of playground environment. To systemize the playground environment design factors and guidelines, we reviewed the previous research, actual measurement and observation were used as the research methodology. And to recognize the needs of users, the survey and picture survey was conducted to the staffs and children. The scope of survey included child care centers in Seoul and Daejeon, ultimately selecting 12 places in Seoul and 13 places in Daejeon. In terms of the survey period, actual measurement was conducted from June of 2006 to February of 2007, survey and picture survey was conducted from August to September of 2006. For analysis, we used SPSS 10.0 to check the frequency and percentage, as well as to perform cluster analysis. The findings of research can be summarized as below: 1. In playground environment, we observed the area of play ground and ground cover, the independence of play area, play equipment, and the composition of play area. The result of observation showed that while playground area varied widely, ground cover, play equipment, and the composition of play area turned out to be identical, regardless of the playground's area. Therefore, in order to classify various playground environments, we categorized them into 5 types, using the number of children and the area of play ground as a category. Type A had large facilities and small playground area. Type B had small sized facilities and large playground area. Type C had medium sized facilities and small playground area. Type D had medium sized facilities but large playground area. Type E had large sized facilities and large playground area. 2. On the other hand, staffs wanted a tunnel, playhouse, comprehensive play equipment, and a maze to be installed as play facilities, and there were requests for adventure play area and carpenter play area. The picture survey to children showed that they wanted equipments that can provide more thrill, adventure and challenge to them than the ones they see now. Therefore, existing child care center play environments must change from the monotonous and identical environments to the ones that can provide diversities, challenges, and adventures. In the contexts of 5 playground types suggested by this research, type B and D, E where the area of playground were larger than the legally required, should include various play areas and install appropriate play equipments and facilities. Type A and C where the area were small, should provide multipurpose play area to attract the various play behaviors of children.

This study was carried out in order to seek social support direction by allowing them to recognize necessity of preparing for their stably old age life and by inquiring into the preparation for old age life targeting dental hygienists who work at dental clinics. It sent questionnaire by post to dental hygienists of 1,560 dental clinics, which were sampled with a stratified sampling method, and then conducted a cross-sectional study based on self-administration. As a result of a problem of being worried in old age life, the ratio with the response as saying of being 'economy' was indicated to be the highest. The ratio of financial preparation for old age was shown to be high with 84.3%. Its method was the highest in 'fixed deposit and installment savings' with 62.6%. The satisfaction with financial preparation for old age stood at averagely 2.60, thereby having shown to be dissatisfied. It was shown to be low with 2.97 in the mean score of physical preparation for old age life, 3.59 in emotional preparation, and 2.56 in preparation for leisure. In conclusion, the satisfaction with financial preparation for old age life in our country's dental hygienists was low. Even the physical, emotional, and leisure-based preparations were shown to be low. Hence, it is considered to be likely needed to be planned preparation for old age life from the 30s. Also, for this, Korean Dental Hygienists Association needs to positively develop several kinds of programs such as education, policy and system for old age life following these people's retirement.

This study was conducted to identify the conceptual definitions and attributes of fatigue in hemodialysis patients based on the Hybrid Model of concept development. The Hybrid Model was used to investigate the main attributes and indicators of the concept by applying three stages. After a literature review, data were collected through observation and interviews including qualitative research in the field work stage. The participants included 10 patients in hemodialysis center of two hospitals in Gwang-ju, Korea. The attributes of fatigue concept in the hemodialysis patients were divided into four dimensions, physical activity, affective mood, social role, and cognitive reflection. The definition of fatigue by hemodialysis patients was defined as 'subjective feeling usually experienced in four dimensions during the process to recognize and adjust energy deficiency and limited functions caused by uremia and repeated hemodialysis for chronic renal failure'. Considering the dimensions and attributes derived from this study, it may be possible to develop an effective intervention program for fatigue in hemodialysis patients.

The era of autonomous vehicles, which drive themselves and in whose operation the driver does not intervene, is fast approaching. The safety of autonomous vehicles can be guaranteed only if they recognize the road infrastructure. However, the road infrastructure consists of road safety facilities, traffic operation systems, and cross-sectional concerns, which include a variety of components, such as types, shapes, and sizes. Therefore, it is necessary to prioritize the road information. This study was conducted to select the priority with which the road infrastructure attributes should be acquired using the AHP (Analytical Hierarchy Process) method. The road infrastructure attributes were categorized into 2 levels, levels 1 and 2, which consisted of 3 and 26 types of attributes, respectively. As a result of the AHP analysis, it was found that the highest priorities of the road infrastructure are the road safety facilities, traffic operation systems and cross sectional concerns. Also, in level-2, the priorities of the safety barriers (road safety facilities), traffic signals (traffic operation systems), and the median (cross sectional) are the highest. Also, this study provides application examples of road infrastructure extraction with the Point Cloud. The results are expected to support the recognition of technology for autonomous vehicles.

This paper describes new communication methods for transmitting torque commands between the vehicle controller that determines the amount of power generation in a range-extended electric vehicle and the engine controller that performs it. Generally, vehicles use CAN communication, but in this case, the hardware and software of the existing engine controller must be modified. For this reason, it is not easy to apply CAN communication to small and medium sized automotive reorganize companies. Therefore, this research presents a pin-pin communication method for applying the existing mass produced engine controller to range-extended electric vehicles. The pin-pin communication method converts the driver's demand torque control map inside an mass produced engine controller into a virtual accelerator opening position according to the target speed and target torque of the engine, and converts this to a voltage signal for the existing mass produced engine controller to recognize it. The virtual accelerator opening positions are mounted in the form of a control map in the vehicle controller through the reverse conversion process in an offline environment and are determined by the engine generating power requirements and engine optimal operating point algorithm. These algorithms and signal conversion circuits for engine torque transmission have been mounted on the vehicle controller to conduct the virtual accelerator opening position conversion process according to the engine target torque and to establish the virtual accelerator voltage signal using the signal converter.

This study examined the role of interpretation with various practices in art museums to seek a new meaning and a concept of art museum today. The exploration of interpretation would he a starting point to discuss about on art museums with professionals in each art-related field. While museums recognize the concept of interpretation and the scope of the functions in different levels, the study focused on the practices of collecting and exhibiting that will entrust the museum new realms of activities toward the audience. In particular, its emphases are set force on the information on the collections via the museum's web sites, interpretation policies, and theories and methodologies in exhibition development. Art museum websites well reflect how museums utilize the new medium to enhance the understanding of art works by providing in-depth art historical information, comprehensive contexts, and subject/concept based search methods. In recent decades, these have enacted changes to expand dimensions of interpretive functions in most museums, particularly in the United States and others. In an administrative perspective, Tate Gallery Interpretation Policy became an good example how an art museum put its interpretation philosophy as the basis of interpreting collection and public programs. Tate established functions of intrepretation and education not only within a task-based team but also as an intrer-divisional coorperation to provide an interpretation scheme of information provisions such as guide brochure, audio tour, multimedia content, and library. New environment and trends of museum exhibition, and its development processes stem from communication theories, object interpretation philosophy, display strategies, and various evaluation techniques through audiences, with the communication theories of Shannon and Weaver, Berlo's SMCR(Source-Message-Channel-Receiver) models were perceived as to understand the mechanism to communicate museum exhibits to visitors Suzan vogel's insight into object display strategy helped to conceive the mechanism of object recontextualization. She emphasized that the museum's practice to construe opinions and impressions through object display should be discreet and critical, therefore, the professionals to plan the exhibition should reveal the intention and their practices. For a prevailing new methodology from the field, the interpretive exhibition development processes are articulated as the front-end, formative, and summative evaluation, futhermore the team process in industrial product management models was adapted. These have turned out to be more interactive with visitors and effective to communicate the exhibition concepts and messages, hence resulting in enriched museum experiences. Finally the study concluded that understanding the aspects of interpretation should help art museums to set a framework for current practices to expand its public dimension. It can provide curators with a critical view to website planning and its content. And obviously, the interpretive exhibition development methodology will lead museum exhibition developers to be skilled in its current approaches to thematic exhibition concerning diverse subjects and topics.

Common law makes a distinction between partial breach and material breach. Attempted definitions of material breach are notoriously unsatisfactory, and the concept of partial breach does not necessarily bear an inverse relationship to substantial performance. This study will review the basic structure of common law contract remedies together with how these remedies are reflected in UCC Article 2 for sale of goods contracts. The matter is complicated because availability of remedy depends on the seriousness of the breach, and the right to cure, and (for sale of goods) these in turn depend on whether the contract is an installment contract or a single performance contract. Common law jurisdictions relegate specific performance of contracts to a last place in the hierarchy of contract remedies. Common law lawyers should recognize that this is the result of historical accident and not the product of some kind of superior intellectual effort. Not only is the attitude of civil law systems toward specific performance quite different, but for international sales contracts in developing nations, a remedy system based on the notion that substitute contracts are readily available(and therefore damage remedies are appropriate) is unrealistic. English common law courts were largely restricted to remedies in the form of monetary damages. For that reason the primary contract remedy at common law has never been specific performance. Rather, common law courts have struggled to develop an appropriate measure of monetary damages for breach of contract. Today, specific performance is viewed as an equitable remedy rather than common law. In the United States the dual court system has been abolished by a merger of law and equity courts into a single court structure. However some historical distinction linger on. The most important is that jury trials are generally not available in actions that seek equitable relief. If a plaintiff seeks in personam relief, such as specific performance of a contract, the action will be viewed as equitable and there will be no entitlement to a jury. Further, equitable relief will be granted only in those situations where the plaintiff pleads and proves that the remedy at law is inadequate. The purpose of this study aims to analyze the remedy system of breach of contract of U.K. and U.S. in the international commercial transactions with criterion of commercial rationality.

As for comics and animation, the specific gravity came to become still larger in all the art fields together with the importance in various image media now which is useful and goes the time of the 21st century new media. Especially the demand of users to the vision culture which develops day by day, Sensitivity Engineering Department is trying to realize the necessity for a sensitivity design acutely together. The influence of the comics which have toxicity most also in Japanese culture in a geographical position like South Korea on it, and animation is the actual condition in the reason which has reached from youth universally to the layer for years, to be inquired systematic to a Korean comics language. This research was conducted as we thought sufficient study on various situations are required, and among them for the research of expressions of cartoons's characters, we've divided the expressions of characters that comes out in Japanese cartoons into categories of 'happiness, anger, sadness, pleasure' and 'fear, astonishment and dislike' and based on these categories, we've drawn out the minimum elements to express emotions in cartoon and prepared image-map by relating them with languages that express emotions of people and based on this, we've made a calculating tools on how our readers would recognize the expression languages. Samples of Japanese cartoons of which we've chosen for the purpose of drawing out the elements of expressions were limited to only published cartoons and we've made a foot steps for expression analysis of animation characters in the future.

In this paper, we propose a vehicle recognition system based on the classification of vehicle identification mark and recognition of vehicle license plate. In the proposed algorithm, From the input vehicle image, we first simulate preprocessing procedures such as noise reduction, thinning etc., and detect vehicle identification mark and license plate region using the frequency distribution of intensity variation. And then, we classify extracted vehicle candidate region into identification mark, character and number of vehicle by using structural feature informations of vehicle. Lastly, we recognize vehicle informations with recognition of identification mark, character and number of vehicle using hybrid and vertical/horizontal pattern vector method. In the proposed algorithm, we used three properties of vehicle informations such as Independency property, discriminance property and frequency distribution of intensity variation property. In the vehicle images, identification mark is generally independent of the types of vehicle and vehicle identification mark. And also, the license plate region between character and background as well as horizontal/vertical intensity variations are more noticeable than other regions. To show the efficiency of the propofed algorithm, we tested it on 350 vehicle images and found that the propofed method shows good Performance regardless of irregular environment conditions as well as noise, size, and location of vehicles.

While we interact with other people or objects, the brain continuously updates our own body schema to recognize the agent of observed actions. The Extrastriate Body Area (EBA) provides an initial interface for the sense of agency by integrating visual inputs of body parts with internal signals related to self-generated body movements. Less is known, however, about how the functional use of tools contributes to such processes. Here, we investigated whether tool-specific affordance would differentially affect the neural responses in the EBA depending on the agency of imaginary actions. In each trial we presented a picture of an object in a rectangular frame. Objects were either the tools typically brought towards the body (body tools; e.g., telescope, earphones) or away from the body (world tools; e.g., pen, dice; Rueschemeyer, Pfeiffer, & Bekkering, 2010). Depending on the color of the frame, participants imagined either themselves or the other person using the tool (self vs. other conditions). These four types of trials were randomly intermixed with blank trials. As results, independently localized right EBA regions of interest showed greater activation when participants imagined themselves using body tools than using world tools whereas no such differential activations were found when they imagined the other person using the tools. The postscan test revealed no significant difference in vividness of imagery between the self and other conditions. Our results suggest that the EBA incorporates functional affordance of tools into the body schema in order to enhance the sense of agency and to guide our own actions.
