Illumination in church building has played an important role in making workship space more suitable for divine service. As time has changed, however, the worship space of Protestantism is no longer somber and reverent, but changing into practical and multipurpose space with bright and colorful image. This study investigates intensity of illumination of worship space during day and night respectively and figures out the change of psychological change of congregation in accordance with brightness and color temperature in worship space in order to find out preference and look into the usage and change of illumination in recent Protestantism in compliance with the needs of the time and influence. Then, result value is to be compared to Korean Standard intensity of illumination. Also, the correlation between intensity of illumination and color temperature by Kruithof's curve theory is used to identify the comfortableness of the worship space during day and nigh. And it is a common task of space designers and pastors to map out the worship space in terms of illumination suitable for its own purpose with even more modern and Korean sensibility and to create spiritual space for worshippers by collecting opinions from congregation, the main user of the space. With appropriate usage of illumination in Protestantism worship space, the atmosphere and purpose of worship can be enhanced.

The Donggwanwangmyo Shrine was built in the period of Joseon Dynasty in 1602. There are Clay Statues (Gwanwo, Jangbi, Woojanggun, Juchang, Jojaryoung and so on) enshrined in the inside of the main hall. Original color of these Clay Statues are deteriorated by inorganic pollutant like dust. And the origanal forms were damaged during several process of restorations and repaintings. This study carried out XRD, SEM-EDS, P-XRF and chromaticity measurement for characterization of pigments which painted on Clay Statues. As a result, cinnabar, hematite and red lead were used to paint in pigments for the red and brown colors. Light red pigment was made by gypsum with these minerals that make colors. Graphite and gold were used to color of black and gold pigment, respectively. Green pigment is identified of malachite, atacamite and glauconite. Blue pigment which is clearly painted on Clay Statues is interpreted a morden industrial pigment that were painted at repair work. White pigments are detected calcite, gypsum and silver white. Orpiment and litharge were used to color of yellow and light yellow pigment.

The pH, moisture, solid, total sugar, amylose, viscosity, line spread and color of Tarakjuk containing puffed rice powder were investigated. The pH of rice Tarakjuk was higher than that of puffed rice powder. Also, samples with whole milk powder were higher than fresh milk (p<0.05). The highest moisture contents, 84.56% was observed in rice Tarakjuk prepared with whole milk powder, while lowest 81.04% in puffed rice powder sample with fresh milk (p<0.05). Samples with lower moisture contents resulted in greater solid contents (p<0.05). Higher total sugar contents were noticed in cooked samples than uncooked ones, however no differences were found among cooked ones (p<0.05). Amylose contents of puffed rice powder Tarakjuk were higher than rice sample (p<0.05). The rice Tarakjuk showed higher viscosity and lower spreadability (p<0.05). Higher "L" value was observed in rice. Highest "a" values were shown in puffed rice powder and lowest value in rice with fresh milk (p<0.05). The "b" value tended to be similar to "a" value.

We present a etrospective analysis of arterial embolectomies performed at the Inje University Seoul Paik Hospital. During the period of March 1987 Feburary 1996 twenty-six patients underwent embolectomies, eighteen patients were male and eight patients were female, mean age of patients was 56.8 years. Rest pain was the chief complaint in 24 patients, the remaining two patients complained of long term history of claudication after recovery of acute symtoms. But only 10 patients had sensBrylmotor symtoms. Heart was the most common source of embolization and frequent predisposing factor of embolism was ischemic heart disease in 8 cases and valvular heart disease in 11 cases. The sites of embolization were upper extremities artery in 6 cases, saddle embolism in 2 cases, lower extremities artery in 18 cases and the most common site of embolism was femoral artery in 1 1 cases. Preoperative angiography was taken in the diagnosis and planning of the embolectomy in 1) patients while in the other patient p eoperative angiography was not taken. Only two cases were operated within the golden period of 6 hours and other cases were operated in more than 6 hours after embolization. In all patients, the Fogarty embolectomy catheter was used without bypass surgery via bachial ateriotomy in the embolism of upper extremities artery, bilateral groin approaches in the saddle embolism and transfemoral approach in the embolism of lower extremities artery. However 3 patients were re-operated via transpopliteal approach in the distal poplitiotibial embolism. Eighteen patients received perioperative anticoagulation therapy by heparin or fraxiparine and wafarin was used in 17 patients at the time of discharge and the indication of anticogulation was patients of valvular heat disease andfor atrial fibrillation, peripheral artery atherosclerosis and recurrent embolism. Postoperative results of the embolectomy were as follows: fouteen pateints had excellent results, five cases had symtom improvement after re-operation, B. K. amputation in 1 case who had severe atherosclerosis of lower extremities, recurrent embolism in 1 case and death in 2 cases the cause of death were acute renal failure and cerebral artery embolism, respectively. The complications of the embolectomy were reperfusion syndrome, pseudoaneurysm and intimal dissection in one case each. Conclusively the problems of embolism is delayed diagnosis and increasing number of old aged patient who had suffered from ischemic heart diease. Preoperative angiography was not always needed for embol ectomy. Selective anticoagulation therapy can decrease incidence of re-embolism. In the distal poplitiotibial embolism, embolectomy of tibial artery was difficult.

The detection and distribution of Aeromonas in water supplies were investigated by using the USEPA Method 1605. Water samples were collected from the Han River, finished waters and tap waters supplied from Water Treatment Plants in Seoul monthly from July 2002 to December 2003. Aeromonas species in each water sample were quantified based on the development of yellow colonies on the surface of membrane filter using a selective medium (Ampicillin-Dextrin Agar with Vancomycin). The Quality Control (QC) for this study met the acceptance criteria of Method 1605. The concentrations of Aeromonas species in surface water samples ranged from $1.0{\times}10^{0}\;to\;9.8{\times}10^{3}\;CFU/ml$. Aeromonas species were found only in one tap water sample with concentration of 1 CFU/500 ml. No Aeromonas species were found in any finished water samples. Aeromonas species detected here were identified as A. salmonicida(51%), A. caviae(4.7%), A. schubertti(3.4%), A. sobria(3.8%), A. hydrophila(2.1%), and A. ichithiosmia(0.4%). A. salmonicida was the dominant species, which is of no significance to human health. Chlorine resistance of A. salmonicida was evaluated and as a result, 99.99% of A. salmonicida decreased after 30 seconds exposure at residual free chlorine 0.2 mg/L. These suggest that the waters supplied in Seoul may be safe against the pathogenic agent Aeromonas.

A novel folding process is proposed using a repeated cold-die forging and annealing to form a sterling silver ring. Sterling silver plate was cut into a doughnut shape, and lattices with 0.43-mm line-width were imprinted on it. The sample was folded by forging using dies with slopes of $45^{\circ}$, $60^{\circ}$, and $75^{\circ}$ and annealing. For comparison, samples were also fabricated without annealing. Strain was identified by measuring the length of lattices. Vernier calipers, a Vickers hardness tester, an optical microscope, and a UV-VIS colorimeter were used to determine the size, hardness, microstructure, and body color. Without annealing, cracks occurred. However, successful deformation was possible when annealing was used. The results of macro strain measurements show that the outer diameter and width decreased, while the inner diameter and thickness increased after the final process. The maximum strain was increased 0.128 toward the parallel direction. The Vickers hardness decreased after annealing and increased after the folding process. The microstructure results showed that the grain size increased after annealing but decreased after folding. The color difference based on the Lab index was under 10 for all processes. Eventually, a doughnut-shaped silver plate was successfully deformed into a ring shape by the folding process.

Aronia (Aronia melanocarpa cv. Viking) contains high amounts of anthocyanins, which are susceptible to heat. This study was conducted to identify an efficient coating material for encapsulating aronia extract to enhance the stability of anthocyanins during cooking. Maltodextrin, maltodextrin+gum Arabic, and maltodextrin+carboxymethyl cellulose were chosen as the coating materials, mixed with aronia extract at a ratio of 2:1, and freeze-dried after homogenization. The encapsulated aronia extract was then used as a sulgidduk ingredient. Sulgidduk prepared with the encapsulated aronia had significantly higher values for redness, anthocyanin retention, total phenolic content, and antioxidant activity compared to sulgidduk prepared with non-encapsulated aronia. In addition, the sensory evaluation revealed that sulgidduk prepared with encapsulated aronia produced better color and taste. These results indicate that the encapsulation of aronia extract improved the stability of the anthocyanins in aronia, and encapsulated aronia can be used as a functional colorant in the food industry.

Growing urban areas modify patterns of local land use and land cover. Land use changes associated with urban expansion. One way to understand and document land use change and urbanization is to establish benchmark maps compiled from satellite imagery. Old satellite Imagery is useful data to extract urban information. CORONA is a photo satellite reconnaissance program used from 1960 to 1972 and its imagery was declassified and has been available to the public since 1995. Since CORONA images are collected with panoramic cameras, several types of geometric distortions are involved. In this study we proposed mathematical modeling method which use modified collinearity equations. After the geometric modeling, we mosaicked images. We can successfully extract urban boundaries using GLCM method and visual interpretation in CORONA (1972) and SPOT (1995) imagery and detect urban changes in Seoul quantitatively.
