Simulators were introduced in education as a tool to make advanced training standardized, less expensive, and without danger to those involved. In 1922 in the Unites States, Edward Link presented his homemade flight simulator, which became common place in both military and civilian aviation, known as the "Link Trainer". The development of mannequin simulators used for education, training, and research is reviewed, tracing the motivations, evolution to commercial availability, and efforts toward assessment of efficacy of those for teaching cardiopulmonary resuscitation, cardiology skills, anaesthesia clinical skills, and crisis management. This will provide a brief overview of simulators and trainers in several domains.

In this study, we will analyze the artistic character of Jogakbo as a element of fashion art design. Korean traditional Jogakbo is a common homemade item made from clothing remnants and is a part of the culture of women�s quarters. Currently, Jogakbo is higly regarded for its artistic value and it finds a variety of uses in fashion. In particular, it is striking how its modern-style geometric lines and color composition are congruous with abstract art. In applying Jogakbo to fashion art design, we study the artistic expression of Jogakbo in 4 aspects; namely, line, color, material, and technique; and analyze the 4 artistic characteristics; beauty of naivety, simplicity, moderation and freedom. 8 dresses designed based on these 4 characteristics are presented as examples.

[ $C_f/C-Cu$ ]composites were fabricated by infiltrating molten Cu into different $C_f/C$ preforms prepared by chemical vapor infiltration, resin impregnation and carbonization. The microstructure and properties of the composites were investigated. The results show that Cu in the composites filled the pores and showed network-like distribution. Compared with homemade J204 brush material and certain grade pantograph slider from abroad, the composites have higher flexural strength and better electrical conductivity. The friction and wear properties of the composites are better than that of J204, and closed to that of the abroad material.

Highly ordered and perforated anodic aluminum oxide membranes were prepared by anodic oxidation and subsequent removal of the barrier layer. By using these homemade anodic aluminum oxide membranes as templates, metal selenide nanowires and nanotubes were synthesized. The structure and composition of these one-dimensional nanomaterials were studied by field emission scanning electron microscopy as well as transmission electron microscopy and energy dispersive X-ray spectroscopy. The growth process of metal selenide inside anodic aluminum oxide channel was traced by investigating the series of samples using scanning electron microscopy after reacting for different times. Straight and dense copper selenide and silver selenide nanowires with a uniform diameter were successfully prepared. In case of nickel selenide, nanotubes were preferentially formed. Phase and crystallinity of the nanostructured materials were also investigated.

A program is developed to analyze and design the frequency and rigidity of the corrugated plates with various corrugation shapes (the considered corrugation shapes are triangular and trapezoidal) and 36 kinds of boundary conditions using smeared theory. The system is consisted of input, solution and output routines, and its routine is made up pull-down menu type and run in Window basis using Visual Basic Language. The input routine helps the design engineers to make the input data user-friendly. The solution routine uses the homemade solver. In the output routine, automatic designs can be done using AutoCAD and Intent Tool package by interfacing the input data.

FRMLs consist of thin sheets of high strength metal, which are laminated using a structural adhesive and high strength fibers. ARALL(Aramid-fiber Reinforced Aluminum alloy Laminates) of FRMLs is a new class of hybrid material. HERALL(Heracron Reinforced Aluminum Laminate) i.e. domestic ARALL is made of homemade aramid fibers, adhesives and adhesive technique. Domestic aramid fiber is Heracron manufactured by KOLON and domestic adhesive is epoxy resin manufactured by Han Kuk Fiber. In this study, Fatigue crack propagation behavior was examined in a 2024-T3 aluminum alloy/aramid-fiber epoxy 3/2 laminated composites, HERALL and ARAL $L^{ⓡ}$-2 LAMINATE comparing with 2024-T3 aluminum alloy. The extrinsic toughening mechanisms in HERALL and ARALL were examined, the crack bridging behavior of fibers was analyzed by new algorithm, which measures crack bridging stress, and the crack bridging zone length was measured.

A real-time monitoring of immersed antenna type inductively coupled plasma (ICP) was done with a homemade 2 dimensional voltage probe array to check the uniformity of the plasma. Measured voltage values with a high impedance voltmeter are close to the floating potential of the plasma. As the substrate carrier was moving into a magnetron sputtering plasma diffusive from a $125mm{\times}625mm$ size cathode, measured results showed reliably separation of plasma into the upper and lower empty space over the carrier. Infra red thermal imaging camera was used to observe the cross corner effect in situ without eroding a target to the end of the usage. 3 dimensional particle trace model was used to analyze the magnetron discharge's behavior.

This paper addresses the development and design of the HAUSAT-l (Hankuk Aviation University SA'Tellite-D communication subsystem, which is a next generation picosatellite, developed by SSRL (Space System Research Lab.) of Hankuk Aviation University. The communication subsystem generally consumes the majority of power and volume for picosatellites, and thus its design is critical to the overall satellite and mission plans. The HAUSAT-l designs are implemented by using the 145.84 MHz for uplink and 435.84 MHz for downlink frequency bands. The simulation and test results of the homemade radio and the TNC (Terminal Node Controller) integrated on the HAUSAT - I , a picosatellite scheduled to launch on September 2004 by Russian launch vehicle "Dnepr", are presented for EM, QM and FM, respectively.

This study was designed to investigate the contents of icariin during ripening of Epimedium koreanum with sugar and Soju (25, 30, and 35% alcohol contents) using a homemade method. Contents of icariin of Epimedium wine were examined using high performance liquid chromatography. Icariin levels in Epimedium wine increased during the first 3 days of storage; after 6 days, icariin contents decreased gradually until 30 days. Contents of icariin in Epimedium wine by storage temperature (5 and $20^{\circ}C$) were not different during storage. After 30 days, icaiin was not detected in all tested Epimedium wines. Epimedium wines were assessed for 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) and (ABTS) radical scavenging activity. DPPH and ABTS radical scavenging activities increased in early storage periods, however, after 6 or 9 days, activities decreased gradually.

The purpose of this study was to investigate the preparation patterns of traditional fermented soybean products(jang) from the housewives living in Yangsan. 89.4% of the respondents used once a day, every meal and the frequency of eating was higher with getting older. 70% answered that the taste of their homemade doenjang was good, while only 2.5% were not be satisfied with their doenjang. According to the survey, 82.2% of the housewives used the meju made by the traditional method for jang preparation, of which perparation patterns showed remarkablely in the housewives living in the independent home. On the other hand, we could see that the amount of jang preparated one time in each home of Yangsan region was approximately 6∼10kg or 16∼20kg. The hard tasks of jang preparation were seasoning, storing and meju preparation. Especially, housewives living in the communal house had a difficulty in storing of jang. But most wants to continue to prepare jang by traditional method at home.
