  • Because of development of information technology, moving picture can run various platforms. We should consider and apply users' attitude as well as production technique because convergence between mobile and media technology may be increased full-browsing service using mobile device. Previous research related to production technique in various platforms only focus on video quality and adjustment of screen size. However, besides of technical side, production techniques should be changed such as image production as well as image editing by point of view aesthetic. Mise-en-scene such as camera angle, composition, and lighting is changed due to HD image. Also image production should be changed to a suitable full-browsing service using mobile device. Therefore, we would explore a new suitable production techniques and image editing for smart phone. To propose production techniques for smart phone, we used E-learning production system, which are transition, editing technique for suitable converting system. Such as new attempts are leading to new paradigm and establishing their position by applying characteries such as openness, timeliness to mobile. Also it can be extended individual area and established as expression and play tool.

  • The display technology on the retina is the key role in inspecting the condition of the patients. 2-dimensional retina image is widely used in the eye examination as of today. Recently, 3-dimensional retina image ones have been introduced to this area, but the quality of the image is not fully satisfied to the operator. For the purpose of developing 3-D retina imaging instrument, the optimization of a 3-D retina imaging system using Code-V tool was investigated in this thesis. He-Ne laser having the wavelength 632.8 nm was used to make a power source to detect the retina. Several lenses and mirrors installed on sledge which were developed to perform focus control on 3-D device were designed to make a beam focusing and direct line. Polygon scanner having 24 mirror facets and galvanometer making tilting movement were utilized to make a 2-D laser plane. Also, design of eye ball had been fulfilled to see the focus of the 2-D plane. Reflected ray from retina detected on the sensor array with the same path. All cognitive components were optimized for aberration correction in order to focus on retina. Results of optimization were compared to those of initial designed optics system. On the basis of above results, the result of third aberration has been corrected to stable values to the optical system. MTF evaluating the resolution of an image has been closely correlated to the diffraction limit and PSF indicating the strength distribution of an image has shown the SR value as 0.9998 having high performance. The possibility of new and powerful 3-D retina image instrument was verified by simulating each component of the instrument by Code-V.

  • For successful privatization of environmental facility, a sound environmental policy is required to satisfy social motivation and economic. The primary purpose of environmental facility is not profit, but to supply a good quality service, an efficient management tool is needed to run the facility. In foreign countries, the privatization policy was originally based on the principle of complete competition achieving economic effiency. There were efficient cooperation and division of labor between civillian and public sector. First of all, the local government had independant budget. But, we found that the environmental facility have two important problems, the first is low effiency of operation and the second is comsumed to government finances as a homemade rate 50% in the technic application For a successful privatization of the environmental facility, The law of private capital introduction should be amended to promote fund raising. There are some other strategies ; overcoming of Nimbyism, research development of the privatization, field trip to the successful foreign environmental facilities. To support an efficient privatization policy, the environmental budget should be managed by cost-benefit analysis.

  • This paper proposes an educational community service system that manages information of good quality intensively without overlapping, and that provides an effective searching function by using a personal community with many user layers. This system raises the efficiency of searching and management by using Metadata and Category. It is a self-leading educational community system that brings merits into relief and improves weak points. We constructed an autogenous Blog chain service as a tool which verifies this system, which is called 'EduLOG(Educational Blog) service' Especially we extracted Metadata suitable for this service, which is on the basis of worldfamous Dublin Core Metadata. And we made a new category on the basis of categories which were proposed by some educational community sites and public educational authorities, and we applied it to this system. To ascertain whether this service system provide adequate function or not, we made a questionnaire on the basis of the appraisal table in websites, and evaluated it at the request of experts. In view of the results so far achieved, it returned good scores (above 3.5/5.0) in accuracy of evaluation, low-end reappearance ratio, easiness of registering and approaching information, and intensive management of a categorical information, confirming the efficiency of the ECSS system. Therefore we believe firmly that the ECSS system will play a efficient information storing and searching roles in the near future.

  • Promoting job growth and quality has been central to developing countries to reduce poverty for decades. In this regard, Nepal is not unique in its need to develop effective TVET programme as it is considered showing positive association with workforce development and productivity. While the copious academic literature has highlighted upon staff training programme in general education, it encounters lack of adequate attention in the field of TVET education. The purpose of the study is to identity and prioritise the professional development needs for the teachers of TVET sector in Nepal. A sample(N=317) of Nepalese teachers from seven provinces were asked to answer the scale. The Borich needs assessment model was employed to assess the perceived level of importance and present preferred training modules among 29 teaching subjects. Moreover, a quadrant analysis using 2×2 matrix was used as a diagnostic tool to denote overriding training topics. The result shows that following competence skills constructs were perceived to be in high need of enhancement as well as in existence of discrepancies: 'occupational characteristics of TVET trainer', 'training needs analysis and curriculum development', 'curriculum development based on national competence standard(NCS)', and 'Institution management evaluation'.

  • With the change of medical environment, people are taking interest not just in treatment but in the prevention of oral diseases. As people's interest in oral diseases increases, the number of dental institutions is increasing continuously and this is heightening the necessity and importance of professional dental hygienists equipped with expert knowledge of oral health. Thus the present study purposed to survey and analyze the current state and weight of works carried out by dental hygienists, and to propose dental hygienists' works desirable in the medical environment changing its focus from treatment to prevention. The results of this study are as follows; 1. In the results of dividing dental hygienists' works into oral examination and preliminary examination, preventive works, assistance to dental treatment, oral health education, hospital administration and management, and surveying the performance rate of these works, the work of the highest performance rate in preliminary examination was collection of patients' systemic history (87.6%). It was also scaling (96.9%) in preventive dental treatment, preparation for treatment (96.5%) in assistance to dental treatment, education on the toothbrushing method (92.3%) in oral health education, and tool disinfection and management (72.2%) in hospital administration and management. 2. When the performance rate was surveyed according to age, institution, and work experience, the performance rate by work area was highest in dental hygienists aged between 27~28, those working at a dental clinic, and those with 4~6 years' work experience. 3. The weight of dental hygienists' works was high in order of assistance to dental treatment (59.1%), observation of oral health condition and preliminary examination (12.4%), oral health education (12.4%), hospital administration and management (10.4%), and preventive dental treatment (5.8%), but in the results of surveying perception on the importance of works, the importance was high in order of oral health education (34.7%), preventive dental treatment (29.0%), observation of oral health condition and preliminary examination (19.3%), assistance to dental treatment (11.2%), and hospital administration and management (5.8%), showing that the weight of works carried out current was different from perception on the weight of works regarded as important. 4. To the question on parts to be developed in response to the change of medical environment, the most frequent answers were the establishment of their roles as preventive dental practitioners (75.7%), and the establishment of their roles as oral health educators (74.9%). This was consistent with the works that dental hygienists gave the highest weight to, and suggested that dental hygienists regarded preventive dental treatment as most important. Development of abilities to give counsel to patients was 55.2%, acquisition of theoretical knowledge of dental treatment 42.1%, improvement in quality as a hospital manager 28.2%, and acquisition of skills to assist dental treatment 23.2%. These show that, even with regard to the development of future oriented dental hygienists' capacities, assistance to dental treatment was perceived less important as it was with regard to the importance of work.

  • Design is a fatal factor to differentiate and survive one product from the other in fierce competition of the market, when other conditions such as price or quality makes no much difference. Among many marketing tools, package design is known as a direct communication that visualizes and forms the very initial brand image of a product. Package design is not only for packing, transporting, storing and loading but for engraving the brand image in a consumers' mind and lead them to purchasing. One of recent package design trands is various ways of using character, not just as a printed image on the surface but as a part of three dimensional structure of package. If it succeed, the package design could give out the secondary fun and impact to the consumers. The package design with an effective character is itself a great marketing tool and valuable design asset, which can bring a further profit to the company. Especially, character-package can be a powerful and effective marketing method for various local products, in needs of further publication and sales with limited cost. It should motivate the sales of the products by grabbing their attention and taken as a souvenir. This research takes a character package as a useful marketing method for a local brand in Jeonju, South Korea, and tries to design a three dimensional package using its own character. Through the process, the research aims to propose an important design strategy for repositioning or enhancing an existing brand.

  • Platelet rich plasma (PRP) has been widely used nowadays for several common orthopaedic-related sports medicine conditions with the theoretical basis that PRP supplies numerous autologous growth factors from concentrated platelets needed to promote the healing process of injured tissue. Even though there are many basic sciences, animal studies and some clinical studies regarding PRP injections for musculoskeletal injuries which suggested good results, it is difficult to compare these various studies due to marked methodological differences such as PRP preparation method, the timing, volume and number of injection, and the outcome measurement tool. In addition, many studies have no control groups or a limited sample size, and there are few prospective randomized controlled trials assessing the efficacy of PRP injections. Therefore, well designed high-quality randomized studies are required to confirm the preliminary results until now and provide scientific evidence to support its use, and the paucity of scientific clinical evidence suggest that the administration of PRP on humans for musculoskeletal injuries should be performed with caution.
