  • In this paper, an intelligent demand control system was introduced. This system are composed of demand controller, RTU, power line modem and HMI program. The proposed demand controller was capable of synchronizing with watt-hour meter recommended by KEPCO(Korea Electrical Power Corporation). To control remote loads, network function using powerline communication is implemented in RTU with HMI program and novices are able to operate system easily. Additionally using the power line, the cost and time of installation can b saved. The system performance was proved with a several experiments.

  • Interest in mannual therapy appears to continue to grow among physical therapists. The term 'mannual therapy' has traditionally been associated with physical therapists who examine and treat Patients who have disorders related to the neuro-muscular-articular system.. The manipulative means skilled and specialised use of manual and/or mechanically applied movement techniques, as a part of comprehensive orthopaedic physical therapy for disorders of the moving parts of body. Physical therapists use a large variety of manually applied examination procedures as part of the clincal decision-making process. The purpose of this article is to define and clarify the basic concepts of mannual therapy by comparing the geneal concepts and evaluation schemes of James Cyriax, John McM. Mennell, Geoffrey Maitland, Freddy Kaltenborn, Robin McKenzie, and Ola Grimsby. This article stresses the importance of developing stills in evaluation. Gimsby's approch is presented as a example of modem mannual therapy.

  • For each reference station and user, the proposed DGPS system is implemented by a GPS module and a modem. The reference station makes plans of the receiving schedule from the satellite sets at each period and then provides the correction data for various satellite sets in a period. Users can utilize the correction data continuously and efficiently through the recursive least squares lattice filters. Furthermore, after taking DGPS techniques, we can improve the positioning accuracy using a kalman filter by decreasing anti-common errors between a reference station and a user. Experimental results show the positioning accuracy of better than 5 meters in almost real time.

  • The purpose of this study is to analyze the aesthetic characteristics of grotesque images in fashion specially focused on the postmodern grotesque with the relationship between body and fashion. The results are as follows: The postmodern grotesque fashion images in the years of 1990-2000 can be analyzed as trans-stylistic, trans-boundaries which have been set by the modem western white elite men group. The postmodern grotesque fashion images in the years of 1990-2000 can be categorized as 1) unclear boundaries between genders: body and dress; human being and non-human being; life and death; wholeness and fragmentation; clear body and abject body. 2) violence to the body: body mutation by simplification, exaggeration; body injury.

A Study on Dress Design from the Development of Materials Focused on Tapestry (타피스트리 중심의 소재개발을 통한 의상디자인개발에 관한 연구)

  • This study focused on the development of creative materials by applying tapestry to produce original and high-grade dresses with consideration the modems' tendency to place high value on personal taste and style. The development remained sensitive to current trends and attempted to expand into high value-added dresses. Materials in modem fashion design, as a basis of the fashion industry, can lead to a current of new fashion and produce novel and creative ideas by stimulating the designers' creativity. Designers can diversely express a form according to their intention, since tapestry allows the expression of various feelings of texture and forms according to the combination mode of technique, structure and materials on a basic plane. Moreover, tapestry encrourages the development of varied designs because it can effectively display the texture and color of a textile surface through the careful selection of materials even under the same technique. Tapestry can apply forms similar to a textile's basic structure to fashion design and can create high added value with the merit of being 'handmade'.

  • Case study was peformed to analyze energy load for department stores and develop energy load model to be applied to a cogeneration system. Energy loads of 14 departments were analyzed based on energy load sheets written by operators and energy load of one department store was measured through modem communication for a year. Energy load of department stores shows various variations depending on when they are opened or closed and, hours, days and months. In this paper, the measurement was compared with data in energy load sheets and resolved, and energy load model for a department store was built. It is important to use an accurate energy load model for an accurate feasibility study applying a cogeneration system to buildings.

  • Modem rotorcraft is required to have the capability to operate in all-weather conditions. Also icing condition is important issue to aircraft safety and certification. And rotorcraft icing research has come a long way during the past few decades. The aircraft icing is the most difficult to handle. So, icing-related accidents, incidents and operating problems still occur regularly in service, despite improvements in design and test techniques. By reviewing icing certification requirement of FAR(Federal Aviation Regulations) and KAS(Korean Airworthiness Standard), this paper describes methods how to demonstrate safety in the flight and consideration of icing when rotorcraft is required TC(Type Certification).

  • Modem after-treatment technology has been developed variously in order to decrease exhausted emission in diesel engine. However, it seems very difficult to comply with updated stringent emission standards. Specially, it has been many years that exhaust gas from gasoline automobile rather than from diesel is the major object concerned by Korea and other countries, and it is strongly required on the reduction techniques on harmful NOx and PM among those compositions. Thus, this research focused on the electronic control EGR and the target for this research is heavy-duty turbo-diesel engine with EGR technology(High pressure route and low pressure route system).

  • Miniaturization is the central theme in modern fabrication technology. Many of the components used in modem products are becoming smaller and smaller. The direct write FIB technology has several advantages over contemporary micromachining technology, including better feature resolution with low lateral scattering and capability of mastless fabrication. Therefore, the application of focused ion beam(FIB) technology in micro fabrication has become increasingly popular. In recent model of FIB, however the feeding system has been a very coarse resolution of about a few ${\mu}{\textrm}{m}$. It is not unsuitable to the sputtering and the deposition to make the high-precision structure in micro or macro scale. Our research is the development of nano stage of 200mm strokes and l0nm resolutions. Also, this stage should be effectively operating in ultra high vacuum of about 1$\times$10$^{-5}$ pa. This paper presents the concept of nano stages and the discussion of the material treatment for ultra tush vacuum.

  • Expressing transparency has various significances in modem society because modern people want transparent objects and space due to the complication, numerous unreasonable facts and the lack of honesty in the society. It is necessary to summarize the processes of changes in transparent materials that have been substantially emerging in the areas of indoor spaces and furniture since the 1960s by organizing the concepts such as the characteristics of materials, the processes of development and the methods of shaping centering on representative artists and works. And the concept of transparency in terms of space enabled the expansion, overlapping and connection of spaces. It can be said that these factors express the openness, purity and non-materiality of spaces. It can also be connected to the thought of minimal ism and this concept could be confirmed by analyzing the works of the famous designers leading the times.
