Computer programming in computer education draws much attention recently. Encouraged by the increased tendency of acquiring logical ability and creativity through learning, various attempts have been made to develop them through learning computer programming in the area of computer education as well. The fact that a computer program is the representation of a computer algorithm expressed in a computer language makes us realize that the devise of a logical method for a solution - i.e., the design of an algorithm - is the key to the solution of a problem. Recognizing the importance of computer algorithm would lead us to such a point that systematic investigations for directional establishment for algorithm education are necessary. We observe that researches on teaching computer algorithm have concentrated mostly on specific problems such as sorting and searching, which can be characterized as problem-dependent and individual. In this paper, the idea of conceptual algorithm is stated from the standpoint of conceptual types of problem-solving methods which are considered as problem-independent and collective. A novice approach to algorithm education based on the characteristics of types of conceptual algorithms is proposed for the purpose of developing systematic, problem-independent, algorithmic problem-solving capabilities of learners, which is widely different from the current methods of individual and problem-dependent algorithm education.

Objective: The purpose of this study was to compare the precision of three-dimensional (3D) images acquired using iTero$^{(R)}$(Align Technology Inc., San Jose, CA, USA) and Trios$^{(R)}$(3Shape Dental Systems, Copenhagen, Denmark) digital intraoral scanners, and to evaluate the effects of the severity of tooth irregularities and scanning sequence on precision. Methods: Dental arch models were fabricated with differing degrees of tooth irregularity and divided into 2 groups based on scanning sequence. To assess their precision, images were superimposed and an optimized superimposition algorithm was employed to measure any 3D deviation. The t-test, paired t-test, and one-way ANOVA were performed (p < 0.05) for statistical analysis. Results: The iTero$^{(R)}$ and Trios$^{(R)}$ systems showed no statistically significant difference in precision among models with differing degrees of tooth irregularity. However, there were statistically significant differences in the precision of the 2 scanners when the starting points of scanning were different. The iTero$^{(R)}$ scanner (mean deviation, $29.84{\pm}12.08{\mu}m$) proved to be less precise than the Trios$^{(R)}$ scanner ($22.17{\pm}4.47{\mu}m$). Conclusions: The precision of 3D images differed according to the degree of tooth irregularity, scanning sequence, and scanner type. However, from a clinical standpoint, both scanners were highly accurate regardless of the degree of tooth irregularity.

The e-Learning quality assurance is a part of responsibility for education in latest information age, and should be understood as a basic direction for qualitative enhancement rather than quantifiable expansion. In such a context, this study sought to survey latest trends of e-Learning quality assurance activities deployed around overseas countries, so that it could give possible implications on how to plan and perform e-Learning quality assurance in Korea. So, this study focused on surveying actual conditions, coverage, target and useful indices of e-Learning quality assurance activities deployed by 9 institutions across 5 countries, and characterizing those activities across 5 countries. As a result, this study could find out its implications such as acquisition of various resources available for e-Learning, nationwide consolidation of e-Learning quality assurance activities, development of specialists in e-Learning quality assurance, and choice and focus for e-Learning quality assurance system. In other words, it was found that e-Learning quality assurance should be approached from nationwide standpoint in the interest of better educational quality, rather than from viewpoint of task.

Purpose is the purpose of this study is to develop medical services for the elderly and qualitatively enhance physical therapy for them by analyzing Korean students' attitudes of the elderly through social science convergence. Methods is a total of 1027 male/female undergraduate students majoring in physical therapy were selected to examine the attitudes of the elderly. T-test, One-way-ANOVA and Scheff test were used. Result is positive attitudes toward the elderly was 46.0%. 51.48% in the population over 30, and 47.52% in the male group was more positive. In addition, when the elderly with no experience in the relevant lecture course (t = -2.035, p = 0.0042) in elderly and when the living experience more positive attitudes (t = 2.951, p = 0.003). Conclusion is education of students in the process of aging of the elderly in a positive standpoint, lectures and hands-on so that you can see the need to change direction.

A lot of designers are adopting a mixed imitation as techniques of cretion because cultural boundary and structure of meaning in the era of post-modernism are collapsed and dissolved. I raise up a question mark to how can genuine and creative designers can be identified at this epoch when we are today familiar with the trend of informationalization, opening and globalization. Characterisitics of multi-culturalism and compromising blending are meshed with appearance of a theory of disorganization and consumer-driven economic activity of multi-national enterprises in the age of post capitalism. Accordingly it can be said that designers are leaning upon public and consumeroriented pattern rather than pursuing a creative cultural production. With mass media in rapid advancement and public culture in father dissemination, mass production and mass re-production became a natural cultural phenomenon strengthen ing its root. Creative designers somewhat slow and limitative in pace of adaption to rapid changing society amid such social backgrounds and flooded information are coming to dead-end of wall. A mixed imitation as techniques of creation is a result of borrowing, duplicating or re-combining of existing things because the mixed imitation is equivalent to borrowing, copying, compilation and recombination of well-known artworks, motive, diverse people's cultural features, image, techniques and the likes. It is too delicate thing for one to definitely distinguish such cultural phenomenon from either one as creative work or a plagiarized work. Looking into the facts as they are, we should recognize the designers limitation in their creative works by means of the mixed imitation. thus we can have a view upon them from a criticizing standpoint against the designers creation and imitation. On the other hand, when we look at things how the mixed imitation appears in the fashion as a piece of culture, we can understand something of the contemporary designers. I try to find a significance in seeking out a method of approaching to creative fashion designers direction in future times.

The recent development of embodiment technology of the medical images makes most medical institutions introduce PACS in haste. However, while many older HIS and PACS systems are not yet capable of some of the integration, several new systems are moving rapidly in that direction. Typical PACS system architecture begins with the HIS since this is where the correct patient demographic information and in many cases the orders originate. So, PACS developed convenience of users and to satisfy user's demand because of financial limitations and administrator-oriented considerations in the process of development. Therefore, we have developed a CDA (Clinical Document Architecture) based PACS with HIS, by which we can search and refer to the patient's medical images and information with few restrictions of time and space for diagnosis and treatment. Target model of this research limited to 135 of hospital have 200 beds. We'll make more effort to develop the application which insures the better quality and information of medical images. Medical Image History manages the patient's image files and various medical informations like film chart in connection with time. This trial will contribute to the reduction of the financial loss caused by unnecessary devices and improve the quality in the medical services. The demand on the development of the program which refers to the medical data quickly and keeps them stable will be continued by the medical institute. This will satisfy the client's demand and improve the service to the patients in that the program will be modified from the standpoint of the users.

Carlos Jimenez's 'House and Studio' was self-designed to fully function as both a home and workplace. Since its establishment in 1983, the installation has been continuously updated for almost 30 years solely under the guidance of the owner's life occurrences and routine needs. The additions and alterations succeeding the building's erection were executed to incorporate small yet symbolic fragments of the resident's memories and life episodes. The particularity of the 'House and Studio' can be compared with other residential remodeling and expansion projects in regards to certain key aspects. These means of comparison include, but are not limited to, building strictly under the direction of a master plan of development vs. allowing natural adaptations that comply with the resident's needs, rapid development vs. gradual advancement, the ornamenting by exposing showy features vs. the enhancing by addition of modest natural components, sustainability vs. sustenance, systematic room divisions vs. ambiguous spatial organization, possession as a materialized asset vs. preservation as a recollection of memories, and finally the recognition as one example of signature architecture vs. the witnessing of a maturing animated shelter. The given propositions can be further explained with the comprehension of Erich Fromm's theory of the 'Having' mode and 'Being' mode, two mechanisms that categorize the essence of human life. The 'Having' mode is described by the human greed for wealth, power, and influence, whereas the 'Being' mode is comprised of compassion, joy, and productivity. Fromm's thesis applies to the general sense of human life, but the ideas can be narrowed to accommodate the architectural standpoint. In architecture, the 'Having' mode can be translated to be the conspicuous form-oriented and self-contained object. The 'Being' mode, on the other hand, is transposed as the more natural form, incorporating the needs of the owner before commercialization. The growth of Jimenez's 'House and Studio' can be perceived as an architectural suggestion to the overcoming of human indifference caused by fixation on the 'Having' mode.

Due to rapid urbanization around the world, various social problems and side effects are occurring. Accordingly, the creation of smart city is being promoted to improve the quality of life of citizens and promote sustainable urban development. In Korea, visions and strategies for the creation of smart city have been presented for each ministry within the government. But they are proposed from the standpoint of each ministry, not from the national level. Therefore, it is necessary to establish a vision and core strategies at the national level. In this study, the problems of Korea smart city were derived, and a smart city vision was established as a solution. In addition, STEEP analysis was conducted through Korea and overseas smart city status analysis and literature review, and based on this, CLDs (Causal Loop Diagrams) were drawn up to derive major smart city strategies. The smart city vision and major strategies proposed in this study are expected to be helpful in setting the direction for future successful smart city creation.

By examining care from a normative perspective projected in the Constitution of South Korea, this paper attempts to assess care from the standpoint of justice and establish the status of care as a concrete political value. The point that this paper focuses on in the Constitution is about the "human worth and dignity" and "right to pursue happiness" clauses of the Article 10 at the beginning of Chapter II which defines the rights and duties of citizens. The clauses of "human worth and dignity" and the "right to pursue happiness" are generally interpreted as the highest values of the constitutional order. While exploring the human dignity and the pursuit of happiness clauses in light of care, this paper intends to address the value of care as human dignity, which is the highest ideology and constitutional principle of the Constitution and, at the same time, the limitation of explaining the freedom to care with a liberal concept of freedom implied in the pursuit of happiness. Ultimately, this paper argues for the justification of putting 'care' in the Constitution. In the end, this paper aims to emphasize the significance of care as a guiding principle for the maintenance of our lives and society, a primary principle of social regulation and public governance, and a direction for a just state which can identify and rectify care injustices.

This study was conducted to investigate the changes in the structural parts of the craniofacial skeleton subsequent to chincap therapy in the juvenile skeletal Class III patients. The subject consisted of 29 Korean children(14 males, 15 females) who had skeletal Class III malocclusion and were undergone chincap therapy from the beginning of the treatment (and an auxilliary upper removable appliance, if necessary). The control group was composed of 21 children(10 males, 11 females) with skeletal Class III malocclusion who had no orthodontic treatment. Cephalometric data at the mean age of 7 and 2 years later were analyized by finite element method, and compared between groups by independent group t-test(p<0.05). The results of the present study were as follows; 1. There were no significant changes in the cranial base, posterior face, upper anterior face, ramus, chin and soft tissues by the chincap therapy. 2. The mandibular body showed significant differences in the minimum extention ratio and the overall shape ratio. This means that the vertical direction of growth was retarded by the chincap therapy. 3. The major direction of the growth in the maxillary basal bone was significantly more horizontal in the experimental group, which suggests that the vertical growth of maxilla was inhibited. 4. There was statistical difference in the major direction of the growth of the anterior face between groups. This may be due to the significant difference in the major direction of growth of the lower anterior face, supposed to be resulted from the mandibular rotation and/or displacement by the chincap therapy. The change in the oral functional space seemed to be caused by the same reason. 5. From the standpoint of these results, the retardation of growth, the changes of the growth direction and the morphological changes could be accepted partly, but the major effect of the chincap seems to be the rotation and the displacement of the mandible.
