The purpose of this study is to provide fundamental data for the development of new course on 3D printing in the fashion design department. In order to investigate the perception of and educational needs in 3D printing, the data were collected from 266 students (female 68.8%, male 31.2%) majoring in fashion design aged 18-25 living in the capital area. The results of this survey showed that when investigating perceptions of 3D printing, it was found that 68.8% of answerers had indeed heard of 3D printing. Regarding the path they came to know about 3D printing, mass media such TV was the most frequent answer (54.6%). On the other hand, to the question asking about their intention to take the subject if given, approximately 71% said "Yes". Also, if a modeling class were given, the division that they wanted to explore most in the fashion industry was fashion jewelry. Finally, to the question asking interest in starting a business, 71.1% answered that they had interest. Out of those that answered that they had interest, when questioned about in which field they wanted to start a business, the most frequent answer was fashion online shopping mall. Finally, NCS-based 3D printing courses were suggested in the Fashion Design area. As 3D printing techniques are actively applied to the fashion industry overseas, creative education is needed through the integration of fashion and 3D printing technology by introducing 3D printing related programs in colleges.

This paper studied the safety management network system of infrastructure which constructed smart sensors, closed-circuit television(CCTV) and monitoring system. This safety management of infrastructure applied to bridge, cut slop and tunnel, embankment etc. The system applied to technologies of standardization guidelines, data acquirement technologies, data analysis and judgment technologies, system integration setup technology, and IT technologies. It was constructed safety management network system of various infrastructure to improve efficient management and operation for many infrastructure. Integrated safety management network system of infrastructure consisted of the real-time structural health monitoring system of each infrastructure, integrated control center, measured data transmission using i of tet web-based, collecting data using sf ver, early alarm system which the dangerous event of infrastructure occurred. Integrated control center consisted of conference room, control room to manage and analysis the data, server room to present the measured data and to collect the raw data. Early alarm system proposed realization of warning and response within 5 minute or less through development of sensor-based progress report and propagation automation system using the media such as MMS, VMS, EMS, FMS, SMS and web services of report and propagation. Based on this, the most effective u-Infrastructure Safety Management System is expected to be stably established at a less cost, thus making people's life more comfortable. Information obtained from such systems could be useful for maintenance or structural safety evaluation of existing structures, rapid evaluation of conditions of damaged structures after an earthquake, estimation of residual life of structures, repair and retrofitting of structures, maintenance, management or rehabilitation of historical structures.
Since the Korean War, Korea has experienced modernization. The population increase by baby booming has asked for more space for educational facilities. In such a situation, the purpose of educational facilities was to accommodate continuously increasing students, rather than seeking for quantitative demands. In addition, in accordance with social changes, educational shifts were required. After the revision of the seventh national curriculum in education in 1997, the school buildings became varied. The design of buildings in accordance with educational curriculum has been improved, but still lack of forming comfortable environment and considering energy efficiency in school buildings. For the improvement of educational environments, educational media such as TV and computers have been provided, and energy systems, including heating and cooling systems, has been continuously increased. As a result, it appeared that energy use in school buildings and facilities has been steadily increased and that the structure of energy consumption has been also changed, especially with regard to electricity use. Living in the 21st century, human beings face global environmental issues, such as global warming, geographical climate changes, and ozone destruction that are the consequences of fossil energy use. Therefore, even in industrial areas, considering a counterplan for low energy use is being paid attention. Starting with Kyoto Protocol in 1992, people try to decrease carbon dioxide and to develop alternative energies (i.e. natural energy); for example, solar energy, wind force, terrestrial heat, and water power. Advanced countries already set up a criterion for $CO_2$ decrease ranging from office buildings to residential houses and also propose alternatives for the $CO_2$ decrease. However, there is no such a plan for low energy use and $CO_2$ decrease in school facilities, and any research on the actual conditions was not accomplished. Thus, this study examines energy demand in classrooms that take up a large portion of energy demand in school building structure.
A study was conducted during the period of August 13 to August 18, 1974 to obtain information on knowledge and attitude of the rural area housewife toward health care and antibiotics using. Interviewed 242 housewives dwelling in Soodong and Hwado Myun, Yangju Gun, Kyunggi Do, a typical rural area in Korea and the following results are obtained: 1. Of 242 housewives interviewed, 20.2% were illiteracy, 68.2% was graduated from primary school, 9.1% from middle school and 2.5% from high school. 2. Of those interviewed, 8.7% were Christian, 5.0% Bueldist, 2.9% Confucianism, and 83.4% of those were no religious preference. 3. Utility rate according with the kind of mass media in home was 85.1% of respondants possessed radio, 16.1% of magazine, 12.8% of newspaper, and 4.1% of television. 4. In the case of patients occure in a family, 13.0% out of 242 respondants had chosen physician's clinics for inicial medical care place, 58.4% drug stores, 0.9% herb medicine and 27.7% of those had chosen folk medicine at home. 5. Antibiotics effective complaints listed by the respondants were skin diseases with 43.8%, suppurated wound 30.0%, URI like symptoms 18.2%, diarrhea 14.5%, low back pain 12.9%, fever 6.2%, loss of appetite 3.3%, all kind of diseases 2.5%, urethral discharge 2.1% and tuberculosis 0.8% respectively. 6. Only 14.7% of respondants had obtained antibiotics for medical care from physician's clinics and 85.3% of the respondants had obtained antibioties from drug store (70.7%), village shop (10.4%), and salesmen in street market without any physician's prescription. 7. Eighty-nine percent of the respondants were understanding on patient care activity as the local health subcenter but only 11.0% of those on M.C.H., 29.0% of those on family planning, 21% on vaccination, and only 6.6% on tuberculosis control activity. 8. Utility rate of the local health subcenter was 71.9% out of the patients indicated medical care of medical facilities.
This study was investigated on the consciousness of middle school students in Jeju city about the environmental education through questionnaire, in order to understand the actual conditions of environmental education and to find out the solutions about them. Middle 'school students responded that environmental education in school was taken at the class for the special activity or voluntary service, not in regular class and was worked as in the form of the field trip. They generally obtain the knowledge and informations on the environmental problems from mass media such as TV, radio and newspaper than from regular environment class in school. And 36.0% of students perceive that environmental education is needed as a regular class and 31.3% of students perceive that the regular class in school is effective to the environmental education. These results suggest that many students are interested in the regular environment class in school. However, the most of students responded that the regular environment class in school is not worked or is not worked at all, suggesting that the environmental education in middle school is not worked effectively. Most of students prefer to take the environment class in the form of observation or field trip, and they think that observation or field trip is more effective to obtain environmental informations. In conclusion, the special activity such as observation or field trip needs to be supplemented to regular environment class in order to improve the environmental education in middle school more effectively.

DBS offers actual services to mass-media and communication system of very broad region in information society. Especially, the DBS is the only system to access TV broadcasting service on a sailing ship. But the ship's DBS receiver is required a complex antenna tracking system because ships are under complex moving such as pitch, roll, and yaw etc. This study is motivated to develop a tracking antenna system to receive the koreasat on small silo ship. Therefore, this system is researched to small size, light weight, simple operation, and low cost of the product. The mount structure have been a compact size and easy operation to the Az/El 2-axis type which is operated by step motor. And it is very useful on a ship in the around sea of korean peninsula. The antenna has a plate type of micro-strip array, and is a domestic production. The vibration sensor is selected to gyro sensor of ultra-sonic rate type for ship's moving control. Tracking method is used the step-tracking algorithm, and the ship's moving compensation is adapted to the closed loop control method by ship's moving detection of gyro sensor. Tracking test is operated by the ship's moving simulator, we examined the actual receiving state on sailing shipboard in the near sea of korean peninsular.
Recently, there has been much interest in realistic broadcasting that is a new field following HDTV and 3DTV. In general. the realistic broadcasting is composed of diverse components such as aquisition, authoring, compression, transmission and display, posing many challenging tasks. It is necessary that the types of realistic contents need to be defined prior to the development of realistic broadcasting systems. Based upon them, other components need to be designed and developed. In this paper, we propose some realistic contents suitable to the realistic broadcasting as well as techniques of generating them. Our proposed contents consist of stereoscopic multiview sequences, object-based stereoscopic images, depth map-based image compositing and the composition of stereoscopic real and graphics images. Content generation techniques and their associated software modules are presented with realistic images produced from our experiments. Those contents are produced to deliver stereoscopic perception, immersion and realism to the users as shown in our experimental results.
In this paper we propose the structure of MPEG-4 multimedia player platform for Terrestrial Digital Multimedia Broadcasting (DMB) Service. Korea will launch DMB service at next 2004 you based on Eureka-147 Digital Audio Broadcasting (DAB) Service System. This new mobile multimedia broadcasting services provide not only high quality digital audio broadcasting services, but also various multimedia data broadcasting services including high quality video. For the sake of MPEG-4 Systems technologies, it will provide an interactive service to users in the near future. Therefore it terminal shall have various functionalities as well as playing audio-visual contents. However there is no precedence standard for such mobile interactive multimedia broadcasting system. Therefore it is very import to provide the multimedia player platform of DMB service for accelerating the development process of commercial terminal and providing a direction of next DMB terminal structure.

This paper presents the design of a broadcasting scenario and system for an 8K-resolution content. Due to an 8K content is four times larger than the 4K content in terms of size, many technologies such as content acquisition, video coding, and transmission are required to deal with it. Therefore, high-quality video and audio for 8K (ultra-high definition television) service is not possible to be transmitted only using the current terrestrial broadcasting system. The proposed broadcasting system divides the 8K content into four 4K contents by area, and each area is hierarchically encoded by Scalable High-efficiency Video Coding (SHVC) into three layers: L0, L1, and L2. Every part of the 8K video content divided into areas and hierarchy is independently treated. These parts are transmitted over heterogeneous networks such as digital broadcasting and broadband networks after going through several processes of generating signal messages, encapsulation, and packetization based on MPEG media transport. We propose three methods of generating streams at the sending entity to merge the divided streams into the original content at the receiving entity. First, we design the composition information, which defines the presentation structure for displays. Second, a descriptor for content synchronization is included in the signal message. Finally, we define the rules for generating "packet_id" among the packet header fields and design the transmission scheduler to acquire the divided streams quickly. We implement the 8K broadcasting system by adapting the proposed methods and show that the 8K-resolution contents are stably received and serviced with a low delay.
This study was conducted to investigate the weight concerns of female university students living in Jeonju, as well as their control on behavior. Self-administered questionnaires were collected from 285 students. Statistical data analysis was completed using the SPSS v. 11.0 program. The results are summarized as follows: The average weight, height, and BMI of the subjects were 21.43 kg, 161.93 cm, and 19.8, respectively. With regard to body image, most were dissatisfied with their figures, especially the hips and thighs. About 42% of the students estimated their figures as 'slightly fat', while 5.4% stated 'very fat', even though their BMI classified as 'normal'. Four percent of the underweight students described themselves as being 'fatty'. Approximately 93% of the students had strongly pursued weight control, and 45.3% reported wanting to lose about $2{\sim}5$ kg. Almost 73% of the respondents had weight loss experience. The primary reason for weight control was to improve self-confidence. Only 19.6% had succeeded in losing weight, while nearly 48% had stopped dieting. To reduce weight, about two thirds of the students ate less(e.g. no snacks, no sweets). Fifty percent tried to reduce weight by more physical activity(e.g. sports). Television(50.9%), friends(48.4%), and newspapers/magazines(40.4%) were essential sources of pertinent information. In conclusion, the results show that female students in Jeonju have a great interest in weight reduction. Thus, the majority are willing to try several methods for weight reduction, which however, are not promising and not based on a lasting nutritional change. Therefore, it's necessary to increase cooperation among those concerned(e.g. dietitians, teachers, parents, media) and to develop weight-control programs that take into consideration lifestyle and daily habits, as well as combine physical activity, nutrition, and behavioral and personality training.
