The importance of reliable electric power has increased rapidly with the proliferation of sophisticated communication systems, computers and critical surgical operations and it considered as one of the most important issues which must be reflected on initial engineering for construction. In this connection, this paper describes the basic conception of peak shaving and cogeneration which are widely used to control the electric power supply recently.

The electrons, which are accelerated to nearly light speed from LINAC(Linear Accelerator), put into Storage Ring. And this electrons circulate in an ultra high vacuum chamber and their orbit is controlled by the electromagnets such as DIPOLE, QUADRUPOLE, SEXTUPOLE & CORRECTION MAGNET. Among them, the dipole magnet is to bend the electron and to produce Synchrotron Radiation(S.R). This paper describes the key point during manufacturing of this magnet, and introduce the field measurement results of the HEECO's successful prototype.

As this study is to estimate resistance of cement mortars using crushed sand under chemical attacks. Besides tests have been carried out with cement mortars by river sand and crushed sand by fine sand, cement mortars mix various proportions of silica fume and fly ash(up to 15% and 50% by weight for cement) were prepared and immersed in pure water, sodium sulfate solution, magnesium sulfate solution, seawater for 28days, 60days, 90days and 180days. Test on the change in the weight and compressive strength of cement mortars according to the duration of immersion time and the content of silica fume and fly ash was performed.

This research was performed to activate various new technology for indoor container, and attempt to a desirable planting environment of indoor plant by verify effect that indoor container slit ventilation system gets in growth and root activation of Korea Native Plants. Main result is as following. 1. Davallia mariesii, typical epiphyte fern, was appeared that growth of top and root activation was helped by slit ventilation system in indoor container and were very positive in rhizome development specially. 2. Hedera rhombea was helped growth of top by slit ventilation system, and specially, effect of plant height and number of shoot. Also, this slit system was positive in root activation. So, this indoor container appeared by thing which is very desirable in climbing plants as well as epiphyte plants. According to result that see effect getting in growth and root activation of Davallia mariesii and Hedera rhombea for indoor container slit ventilation system, Growth of top was different in plant but root activation was developed.

Thermo-chromic Liquid Crystal(TLC) particles were used as temperature sensor for thermal fluid flow. 1K $\times$ 1K CCD color camera and Xenon Lamp(500w) were used for the visualization of a Hele-Shaw cell The characteristic between the reflected colors from the TLC and their corresponding temperature shows strong non-linearity A neural network known as having strong mapping capability for non-linearity is adopted to quantify the temperature field using the image of the flow. Improvements of color-to-temperature mapping was attained by using the local color luminance (Y) and hue (H) information as the inputs for the constructed neural network.

Review is made on the sweat in 'Donguibogam' from the view point of Hyungsang medicine. The conclusions are as follows: Clinically sweet is an important indicator for the condition and constitution of the patients. Sweat should be taken into consideration in diagnosis and treatment. Sweat is one of the symptoms that appears when there is a disharmony among Jung(精), Ki(氣) and Shin(神). The cause and phase of sweat varies with every patient. Dam type persons (膽體) are inclined to have night sweat, while Bangkwang type persons(膀胱體) are apt to have day sweat.
