In this study, the assessment and the factor analysis of the self-directed learning readiness for engineering students were conducted. As measurement tool was used the self-directed learning readiness scale of Guglielmino's SDLRS questionnaire in Korean translation. It was surveyed under 519 students of Faculty of Engineering of Korea University of Technology and Education. Responded questionnaires were 496. As a result, seven factors were identified: (1)openness to learning, (2)initiative and inquiring mind, (3)independence and basic learning skills, (4)creativity, (5)accepting responsibility for learning, (6)love of learning, (7)positive orientation of the future. And the scale was confirmed in validity. It was confirmed that the mean value of openness to learning and of love of learning were higher than average, while mean value of independence and basic learning skills, accepting responsibility for learning were lower than average, there was the difference in SDLRS by students' personal backgrounds, but there were statistically significant differences in seven factors.

This study is designed to evaluate the contents of the separation of prescribing and dispensing roles(SPD) policy based on the theoretical backgrounds. The results are as follows; Considering the purpose of SPD policy, 'increasing the efficiency in manpower management by separating the role of medical doctor and pharmacist and improving the quality of SPD service through specialization of function' as a policy objective is valid and very important agenda in health care. But the objectives are not working well by no keeping the detail means to actualize it. Also, some policy objectives are unclear or inappropriate and it makes the focus of that policy obscure or misleads inadequate policy alternatives. In terms of means of policy, it is evaluated to have some limits in effectiveness, efficiency, equity, rationality, technical feasibility, economic feasibility, administrative feasibility, social and time feasibility. In conclusion, it's necessary to investigate the some problem mentioned in this paper with empirical evidence. Also, it should be needed to improve the validity of policy by correcting policy objectives and means in execution of policy.

Since seasonal changes, blooming of a flower, etc., which take place in accordance with passage of time, transpire over an extended duration of time, one performs the Time-Lapse so that one can watch them quickly by compressing time. Because such a Time-Lapse records a wide range of conditions including the place, angle of view, and time found in a natural state in accordance with a precise interval of time and in the samestate, it is also referred to as Interval recording. The Time-Lapse technique is used widely in various fields such as education, science, documentary, and the media. In terms of acquiring a Time-Lapse image, by making it possible for one to treat an image by deleting and adjusting unnecessary backgrounds excluding the main subject for photography such as the flower unlike existing methods and by making it possible for one to apply extensively the real-life recorded image as a library or image data in 2D or 3D, the present study seeks to propose a technique for the background treatment of Time-Lapse image that allows for everyone to bestow creativity to image production easily and conveniently.

Background Many surgical specialties have had pioneering influences from plastic surgeons. However, many of these areas of practice have evolved to include surgeons from diverse training backgrounds. This raises the question as to whether the prominence of other specialties in clinical practice translates to greater research productivity in these areas. The objective of this paper is to investigate the publication volumes of plastic surgeons in selected areas of practice compared to surgeons from other disciplines. Methods PubMed was used to examine publication trends in areas associated with plastic surgery. Searches for the following topics were performed: head and neck reconstruction, hand surgery, breast reconstruction, ventral hernia repair, abdominal component separation, brachial plexus injury, craniofacial surgery, and aesthetic surgery. Affiliation tags were used to examine contributions from nine specialties. Web of Science was used to identify the top cited articles for the last 10 years in each area. Results Articles by non-plastic surgeons comprise the majority of the literature for all areas of practice studied except for breast reconstruction and aesthetic surgery. Despite this, plastic surgeons contributed the greatest number of top cited articles over the last 10 years for five of the areas of practice. Conclusions While plastic surgeons do not contribute the greatest proportion of articles published each year in several of the selected areas of practice, they do publish a larger number of articles that are the most cited. Plastic surgeons remain the dominant academic force in terms of volume and citations for both breast and aesthetic surgery.

The existing subtract image based intrusion detection system for CCTV digital images has a problem that it can not distinguish intruders from moving backgrounds that exist in the natural environment. In this paper, we tried to solve the problems of existing system by designing real - time intrusion detection system for CCTV digital image by combining subtract image based intrusion detection method and background learning artificial neural network technology. Our proposed system consists of three steps: subtract image based intrusion detection, background artificial neural network learning stage, and background artificial neural network evaluation stage. The final intrusion detection result is a combination of result of the subtract image based intrusion detection and the final intrusion detection result of the background artificial neural network. The step of subtract image based intrusion detection is a step of determining the occurrence of intrusion by obtaining a difference image between the background cumulative average image and the current frame image. In the background artificial neural network learning, the background is learned in a situation in which no intrusion occurs, and it is learned by dividing into a detection window unit set by the user. In the background artificial neural network evaluation, the learned background artificial neural network is used to produce background recognition or intrusion detection in the detection window unit. The proposed background learning intrusion detection system is able to detect intrusion more precisely than existing subtract image based intrusion detection system and adaptively execute machine learning on the background so that it can be operated as highly practical intrusion detection system.

Purpose: C57BL/6 mice, which are among the most common backgrounds for genetically engineered mice, are resistant to the induction of periodontitis by oral infection with periodontal pathogens. This study aimed to develop a periodontitis model in C57BL/6 mice using coaggregation between human pathogens and the mouse oral commensal Streptococcus danieliae (Sd). Methods: The abilities of Porphyromonas gingivalis ATCC 33277 (Pg33277), P. gingivalis ATCC 49417 (Pg49417), P. gingivalis KUMC-P4 (PgP4), Fusobacterium nucleatum subsp. nucleatum ATCC 25586 (Fnn), and F. nucleatum subsp. animalis KCOM 1280 (Fna) to coaggregate with Sd were tested by a sedimentation assay. The Sd-noncoaggregating Pg33277 and 2 Sd-coaggregating strains, PgP4 and Fna, were chosen for animal experiments. Eighty C57BL/6 mice received oral gavage with Sd once and subsequently received vehicle alone (sham), Fna, Pg33277, PgP4, or Fna+PgP4 6 times at 2-day intervals. Mice were evaluated at 5 or 8 weeks after the first gavage of human strains. Results: Fnn, Fna, and PgP4 efficiently coaggregated with Sd, but Pg33277 and Pg49417 did not. Alveolar bone loss was significantly higher in the PgP4 group at both time points (weeks 5 and 8) and in all experimental groups at week 8 compared with the sham group. The PgP4 group presented greater alveolar bone loss than the other experimental groups at both time points. A higher degree of alveolar bone loss accompanied higher bacterial loads in the oral cavity, the invasion of not only PgP4 but also Sd and Fna, and the serum antibody responses to these bacteria. Conclusions: Periodontitis was successfully induced in C57BL/6 mice by oral infection with a P. gingivalis strain that persists in the oral cavity through coaggregation with a mouse oral commensal bacterium. This new model will be useful for studying the role of human oral bacteria-host interactions in periodontitis using genetically engineered mice.

Maintaining our tradition makes us have pride for our nation and plays important role for recognition and establishment of identity for our unique culture in the world. Contrast to the western scientific technique, the scientific technique of Silla Bell absorbed in the life of our nation is the fruit of wisdom science found through rich life and experience by harmony between our nation and nature. Today, ideological backgrounds for many cultural heritages weren't be found and there are many overflowing hypothesis. Silla Bell is the plastic art including cumulative utopia of the racial spirit. So there would be the information of the racial spirit including symbolization, artistry, creativity, and historicity. However, unlikely with the words, it is the profoundly concentrated shape, so the meaning can be diluted or distorted in later generation. The efforts to figure out the symbolization in Korean bells, especially Silla bell according to its exclusive shape, but no hypothesis was accepted as an established theory of academia by gaining extensive agreements. Thus this paper traces the symbolic meaning accumulated in the shape and prepares for the theoretical background accessing to the artistic spirit of forebears who created super-humanity formativeness. Also regarding the Silla bell which is regarded as the best Buddhist metal craft that people believe they can be free from the anguish at the time of listening to its sound, we studied the symbolization of the bell as the religious ritual custom as well as the possibility to utilize the bell as a motif of living art in the aspect of formative expression.

The suggestions that follow are about the device to assure the effectiveness of administrational regulation and supervision in Korean private security. First, government clearance should be reinforced. For this it is necessary that the qualification for security dealer-careers and academic backgrounds with security etc.- should be elucidated in Security Law. Also it should be achieved to increase the capital fund and to keep security guards for insuring substitutional manpower. Second, after legal permission governmental supervision should be done in quality by means of setting up the competent institutions independently. Third, the punishment for obtaining security license mendaciously, carrying out illegal or unfair task and assigning Security Guard Supervisors expediently should be strengthened. Also to prevent expedient acts it is necessary to prescribe illegal or unfair acts in the concrete in Security Law and violators should be legally responsible. Fourth, to lay the foundation for security industry itself and make up for perfunctory governmental direct System for Professional License (of private security guard) should come into effect.
