In this paper we present a newly improved telescope control software and a newly developed data analysis software package for effective use of the Solar Flare Telescope(SOFT) The telescope control software permits us to make not only auto tacking of the SOFT, but also quantitative measurement of the solar irradiation, allowing us to provide weather monitorings. In addition we introduce an IDL widget software package for both monochromatioc (MONO version) and polarimetric data (VMG version) analysis. The MONO version is capable of loading FITS files, changing colors and contrast, image processing, displaying plots, and saving displayed plots by selected formats The VMG version, on the other hand provides a calibration of polarimetric data and plots of reduced vector magnetic fields.

SOFT( So–––lar F––lare T––elescope So_larF_lareT_elescope ) installed at BOAO(Bohyunsan Optical Astronomy Observatory) is purposed for observing solar active regions using four refractors on single mount with a 400"×300" 400"×300" field of view: Two refractors with a diameter of 15cm(f15) are observe the white light and Hα Hα , and the other two refractors with a diameter of 20cm(f8) are observe the magnetic field distribution and Doppler shifts at the solar chromosphere. Three Lyot filters, one of the most important observational instruments, are installed on the optical rails for VMG, LMG, and Hα Hα that possible to very narrow pass band observation under high precision stability of temperature. From the combination of KD*P and quarter wave plate in the Lyot filter possible observe the magnetic fields strength and doppler shifts by using the characteristics of polarization components. In this paper, we introduce the basic characteristics, optical system, and monitor system of the SOFT.

Sweet potato β-amylase is a tetrameric enzyme consisting of four identical polypeptide chains with a molecular weight of 5.6×10 exp (4), though most of the other β-amylases are monomeric enzymes. But, the relationship between subunit structure and catalytic function of the enzyme is not known. This study was done to know what the function of the subunit structure of the enzyme is. We obtained the monomer from the enzyme by the treatment of SDS, alkali pH buffer and urea. But the monomer had not activity. We tried to prepare the active monomer from the enzyme by the modification with periodate-oxidized soluble starch. In the result, we succeeded in isolating an active monomer as an oxidized soluble starch-conjugated form. The active monomer had 57% of the original activity, 13.2% of the sugar and the molecular weight was estimated to be 6.4×10 exp (4). This results suggest that the tetrameric form of the enzyme is a most stable one and exists in nature, and the subunit structure of the enzyme plays an important role in stabilization but not catalytic function.

Background: Salvia has been widely cultivated for use in flavoring and folk medicines in many countries, including Korea and China. In this study, we investigated the anti-inflammatory activity and the underlying active compounds of Salvia extract and its fractions.Methods and Results: The anti-inflammatory activity was measured by assessing the inhibition of cysteinyl leukotriene production in rat basophilic leukemia (RBL)-2H3 mast cells. Salvia plebeia R. Br. was found to have the most potent inhibitory activity on leukotriene production than S. japonica and S. chanroenica had. Fifty percent ethanol extracts of S. plebeia R. Br. were successively partitioned with n-hexane, methylene chloride, ethyl acetate, 1-butanol and water. The ethyl acetate (EtOAc) fraction showed stronger anti-inflammatory activity than other solvent fractions did. The EtOAc fraction was subjected to silica gel column chromatography elution with a chloroform and methanol gradient system (100 : 1 → 1 : 1) yielding 10 fractions. Three kinds of fractions (chloroform:methanol = 20 : 1, 10 : 1 and 5 : 1) showed high inhibitory activity on leukotriene production. We confirmed the major compounds with anti-inflammatory activity from S. plebeia R. Br.Conclusions: In this study, the major components of S. plebeia that showed leukotriene production inhibitory activity were isolated using solvent extraction and silica gel column chromatography. Rosmarinic acid, hispidulin and luteolin were identified as the major compounds with anti-inflammatory effect.

본 연구에서는 기능성이 우수한 도라지를 이용하여 흑도라지를 제조하였으며, 흑도라지 추출물, 사과즙, 대추추출물의 혼합비율을 달리하여 흑도라지 사과주스를 제조하고 각각의 품질특성과 기능성을 분석하였다. 흑도라지 사과주스의 pH는 3.90∼4.15이었으며, 산도는 1.2에서 1.5 사이를 나타내었다. 당도를 측정한 결과 흑도라지 사과주스 E가 가장 높은 값(9.33 °Brix)을 나타내었으며, 환원당 함량의 경우 흑도라지 사과주스 E가 85.05 mg/mL로 가장 높은 함량을 나타내었고, 흑도라지 사과주스 B가 41.23 mg/mL로 가장 낮은 함량을 보였다. 당산비 수치의 경우 당도와 환원당 함량이 가장 높은 흑도라지 사과주스 E가 6.98%로 가장 높은 수치를 보였다. 색도는 명도와 황색도는 흑도라지 사과주스 E가 가장 높았으며 적색도는 흑도라지 사과주스 C가 가장 높았다. 관능적 특성을 측정한 결과 향미를 제외한 모든 항목에서 흑도라지 사과주스 C가 가장 우수하게 나타났다. 총 폴리페놀 함량은 흑도라지 사과주스 D가 가장 높은 폴리페놀 함량(706 ㎍/mL)과 항산화 활성을 보였으나 흑도라지 사과주스 C와 항산화 활성에 유의적인 차이는 없었다. 따라서 흑도라지 사과주스 C가 관능적 특성 및 항산화 활성이 우수하여, 흑도라지 사과주스 제조를 위해 흑도라지 추출물, 사과주스, 대추추출물을 2:4:1의 비율로 혼합하는 것이 가장 바람직 할 것으로 판단된다.

This paper presents a finite element analysis to evaluate thermal conductivity of FRP (Fiber Reinforced Polymer) retrofit system in reinforced concrete structure. Especially, this paper focused on near-surface-mounted retrofit method; FRP is mounted into the groove after making a groove in concrete. Midias-FEA program was used to analyze the case that the epoxy was covered by various board to resist fire such as, calcium silicate or alumino silicate board. Analysis results give that the prediction of temperature transition from surface is possible by FE analysis and the result can be used to evaluate fire resistance of certain fire proof materials in FRP retrofit system.

Recently, retrofit by using fiber reinforced polymer (FRP) has been widely applied to building structure. However, it loose the retrofit contribution under high temperature due to fire because of its low glass transition temperature. In this manner, this paper presents a study on the development of fire resistant capacity in FRP retrofit system. Thermal transition of various fire resistant materials were verified by performing high temperature loading test. As a result, it was found that calcium silicate and alumino silicate had high resistance on the heat transition.

For the reclamation of HEP (1-hydroxyethylpiperazine) and MDG (methyl diglycol) from waste photoresist stripper, lab-scale experiments with a packed bed vacuum column were carried out. Purity of recovered solution mixture of HEP and MDG was measured to be 99.3% and recovery yield was to be 65%. Those results confirm that some organic solvents reclaimed from waste PR stripper satisfies the product specification required for the formulation of photoresist stripper.

Recently, retrofits by using fiber reinforced polymer (FRP) have been widely performed for strengthening of reinforced concrete structure. However, in spite of the weakness of FRP for fire, the research result of it is not enough for practical use. In korea, fire is most frequent disaster which occurs in building. This means the improved structural capacity of building by a retrofit with FRP may be lost by fire if the FRP was not properly protected from it. In this paper, a fire analysis result is presented for the evaluation of damage of reinforced concrete member enhanced by FRP. As a result, the loss of strength of RC member is able to be predicted by using FE analysis with proper material properties for temperature variation.

This study was carried out to evaluation of biomass generation mechanisms and to propose the estimation method of biomass generation. Agricultural by-product biomass is generated during crops cultivation and after harvest. However these are not uniformly generated yearly and these depending on the seasons. For planning of biomass utilization, accurate information of the biomass resources is needed, especially characteristic and productivity of biomass are necessary. Agricultural by-product biomass are generated in a wide area being scattered and it is one of the major reason why agricultural biomass utilization is not activated compared with other waste biomass. In this study, estimation and evaluation biomass generation is achieved in specific spatial and temporal boundary, A-city in Gyeongi–do and september to November respectively. Quantity and quality of by-product biomass show big difference depending on the crop species and cultivation periods and these difference bring up that accurate biomass estimation should be considered during planning of biomass utilization and technology selecting for biomass converting to energy and other forms.
