To investigate the pigments used in modern and contemporary oil paintings, thirty-two paintings by Jiho Oh and Bonung Gu were selected. The white pigment found in the ground and painting layers was identified as lead white (hydrocerussite), zinc white (zinc oxide), titanium white (titanium dioxide in anatase or rutile forms), calcite (calcium carbonate), and barite (barium sulfate). Further, this indicated that pigments differ according to the artist and date of the painting's creation. However, both Oh and Gu used zinc white during the modern and contemporary period, while lead white was replaced by titanium white, barite and calcite. Compared with the overseas studies on pigments and oil paints, the change patterns of pigments were the same with them but the periods of the use were partially different. It seems to be due to the fact that South Korea is linked to the historical background of the art material which was imported from Japan instead of Western countries. Therefore, it is inevitable that any change in the white pigments used for domestic oil paintings occurred at a different time from global transitions. If the results of this study are used in the analysis of art works it is suggested that a database recording such aspects as material properties of oil paints, artistic techniques, and chronology would become important for future conservation science and the study of art history.

This study was conducted to evaluate the quality characteristics of different soy sauces. The soybean sauces brewed tty the A. oryzae koji(SAO), M. pilosus-1 koji(SMP) and the mixture of 50% M. pilosus-1 koji(SAM) during 90 days fermentation. Total nitrogen contents of the SAM, SAP and SMP were 13.6%, 1.15% and 1.22%, respectively. Content of amino type nitrogen in SAM was 0.78%, and the content was higher than those of SAO and SMP. Total free amino acid contents of SAO, SMP and SAM were 533.8, 732.4 and 807.3 mg/100 mL. The highest contents of free, amino acids were glutamic acid(65.20 mg/100 mL) in SAG, alanine(101.42 mg/100mL) in SMP, glutamic acid(130.52 mg/100 mL) in SAM. The highest activities of pretense and ${\beta}$-amylase showed in SAM, and the lowest activities of ${\alpha}$-amylase and glucoamylase were in SAO and SMP respectively. Hue angle values showed 56.3 in SAO, 29.0 in SMP and 32.2 in SAM. Monacolin K contents, as inhibitor of cholesterol bio-synthesis were 6.21 $\mu\textrm{g}$/mL for SMP and 3.10 $\mu\textrm{g}$/mL for SAM, and the inhibitory activities of SMP ane SAM aginst HMG-CoA reductase were 21.5 md 10.2%, respectively. Sensory scores for color, flavor, savory taste and overall taste of SAM was higher than those of SAO and SMP.

There are fifteen solar radiation measurement stations over the entire country in Korea. However, they are not capable of supplying reliable solar radiation data for remote areas including islands. The un-manned automated insolation measurement station is suitable for these areas due to the electric power shortage and the maintenance problems at these isolated areas. Our main aim in this work is to develop a solar radiation measurement system which collects and stores data by itself utilizing a PV module and a battery as power source for entire system irregardless of the environmental condition. A developed KIER's prototype system along with an independent HWS reference system has been installed at the designated remote island, Dok-do. Global solar radiation has been measured every hour for a 6-month period of time by both systems at this site. A comparison between the measured solar radiation data by each system indicates that there is an excellent agreement showing average 3.0% of an absolute error. It has been observed that the 8-month average global solar radiation was $2,330W/m^2$ day at this island. We came to the conservative conclusion that the developed KIER system is applicable for measuring solar radiation and for supplying reliable fundamental design data for solar energy utilization system at the remote areas.

Volatile flavor components of soybean koji kochujang made from a glutinuous rice by improved method were analyzed by using a purge and trap method during fermentation, and identified with GC-MSD. Fifty-six volatile flavor components including 16 alcohols, 15 esters, 7 acids, 4 aldehydes, 5 alkanes, 3 ketones, 1 benzene, 1 alkene, 2 phenol and 2 others were found in improved kochujang. The number of volatile flavor components detected immediately after making kochujang were 32 and increased to 46 components after 30 day of fermentation. The most number 55 of volatile flavor components were found after 90 day of fermentation. Thirty-one kinds of volatile flavor components were commonly found through the fermentation period 9 alcohols such as 2-methyl-1-propanol, ethanol, 3-methyl-1-butanol, 8 esters such as methyl acetate, ethyl acetate, 2-methylpropyl acetate, 3 aldehydes such as butanal, acetaldehyde, furfural and 11 othesrs. Although the various types of peak areas (%) of volatile flavor components were shown in kochujang during the fermentation days, ethanol. ethyl acetate, ethyl butanoate, 2-methylpropyl acetate, 2-methyl-1-propanol and 3-methyl-1-butanol were mainly detected during fermentation. Those might be the major volatile flavor components in kochujang made by improved method. Peak area of ethanol was the highest one among the volatile flavor components at immediately after mashing and 90 day while ethyl acetate showed the highest Peak area after $30{\sim}60$ day of fermentation and 3-methyl-1-butanol showed the highest peak area after $120{\sim}150$ day of fermentation.

Pseudomonas sp. GRC3 produced extracellular chitinase(s) and ${\beta}$-1,3-glucanase(s), possible biocontrol agents. Both of enzymes appeared to inhibit the growth of plant phathogens, especially Phytophthora capsici. Antifungal activities of Pseudomonas sp. GRC3 determined was more than 78% inhibition rate against P. capsici.

우리나라 전체 산업재해의 상당수가 상시근로자 300인 미만의 중소기업에서 발생하고 있어 산업재해예방을 위한 주된 노련이 중소기업에서 이루어져야 함에도 불구하고 중소기업이 경영여건 등 제반사유로 인하여 중소기업의 자율적 안전 관리가 미흡한 것이 우리의 현실이다. 현재 대다수의 중소기업은 대기업의 납품업체 또는 하청업체로써 생산 활동을 하고 있으며, 중소기업의 산업재해는 대기업에서 필요한 부품의 납품지연이나 생산차질로 연계되기 때문에 대기업과 중소기업이 하청으로 연결되어 있는 경우 근로자의 안전보건 문제는 대기업이나 중소기업 모두에게 있어 생산활동에 중요한 관리대상이 되고 있다.(중략)
