  • Volatile components of domestic Meju and Doenjang were extracted by simultaneous steam distillation extraction, and analyzed by GC-MS. Sixty-four kinds of compounds were identified from neutral fraction. The contents of pentanal, hexanal and 1-octen-3-ol were high in cooked soybean while those of 3-methylbutanal and 1-butanol were high in Meju. In the case of Doenjang, so many compounds including acetic acid, ethylester were identified which was not appeared in Meju. The main compounds in Meju were 3-methyl-1-butanol, 2-furancarboxyaldehyde, 1-octen-3-ol, benzeneacetaldehyde, methyloctadecadienoate and methyloctadecenoate. Of the eleven compounds identified from basic fraction, the contents of 2,6-dime-thylpyrazine, trimethylpyrazine and tetramethylpyrazine were high in Meju and Doenjang. Nine kinds of compounds were identified from phenolic fraction and appeared that 4-vinylphenol and p-ethylguaiacol were major compounds in Meju and Doenjang. Fifteen kinds of volatile compounds were contained in acidic fraction. Only four acidic compounds were identified in cooked soybean and Meju, but in Doenjang ten compounds were identified which did not appeared in other samples. Among them pentadecanoic acid was major compound.

  • The genus Armillaria is important because they produce Gastrodia tubers. Seventy two isolates of Armillaria were obtained from fruit bodies grown on decayed wood in Korea. Twenty four isolates from Pinus koraiensis were identified as A. ostoyae. Two isolates from G. elata growing in the field were identified as A. mellea. Seven isolates from Acer ginnala and Quercus spp. were identified as A. tabescens. Thirty nine isolates were identified as A. gallica. Armillaria gallica was isolated from Quercus spp., Ainus japonica, Vitis amurensis and Prunus sargentii. Armillaria spp. isolates were divided into four groups based on the cultural characteristics. Group II (A. gallica KNU-A110) was better than the other groups for mycelial growth and rhizomorph formation. Isolate KNU-A110 proved to be good for production of G. elata tubers. This fungus forms mycelial fan in the plant tissue and rhizomorphs in contact with G. elata tubers. Gastrodia spp. was found in thirteen sites in Kangweon province in Korea. The plants were divided into three different kinds based on stem color. Plants with stems of brownish orange and greyish yellow were identified as G. elata, and those with greyish green colored stems were identified as G. gracilis. Gastrodia was collected mainly from humus soils rich in leaf debris, and slopes facing south from mid-May to mid-July. Once the new tubers are formed from the ancestry tuber, the ancestry tuber begins to decay. The offspring tuber, apparently gaining nutrients through rhizomorphs, begins to grow in length and slowly to enlarge. It takes three years for the offspring tuber to become ancestry tuber.

  • In this paper presented is a temperature controller for a semiconductor test handler. Using ARMAX model and least square method, the chamber model for the design of a controller is identified through experiment. With the identified model an LQG/LTR controller is designed. Experiment with a real test handler demonstrated good performance in that its overshoot is small and response time is fast.

  • In this paper, impulse response of giant magnetostrictive material (GMM) is identified by using M-transform. First, the displacement of GMM was measured by using the dual frequency laser interferometer. The noise included in the measured signal was removed by using M-transform. The impulse response of the GMM was identified from the input current of the driving coil and the displacement.

  • In this paper, we design a nonlinear adaptive controller using wavelet neural network. The method proposed in this paper performs for a nonlinear system with unknown parameters, identification with using a wavelet neural network, and then a nonlinear adaptive controller is designed with those identified informations. The advantage of the proposed control method is simple to design a controller for unknown nonlinear systems, because we use the identified informations and design parameters are positioned within a negative real part of s-plane. The simulation results showed the effectiveness of proposed controller design method.

  • A cytotoxic material was produced by strain No. 5-99 which was isolated from soil. Analyzing the cell wall components, LL-diaminopimelic acid was identified. From the existance of glycine in the cell wall, this strain was identified to Streptomyces sp. which has cell wall chemotype I and peptidoglycan type A3 connected by glycine. So, we named this strain to Streptomyces sp. YJB-599. The Active material was purified through solvent extraction, silica gel column chromatography and crystallized to needle-shaped white -crystal. Analyzing the structure of this crytal by instrumental analysis and database, it was determined to genistein.

  • Phytoplankton flora of Chinyang Lake and Hapchun Lake were studied. A total of 161 species(Chinyang Lake, 135 species; Hapchun Lake, 80 species) were identified. The major species of two lakes were Melosira granulate var. angustissima and M. italica. As the bloom causing species, Microcystis aeruginosa, Ceratium hirundinella, and Peridinium sp. were identified. The chlorophyll a concentration of Chinyang Lake was higher than Hapchun Lake.

  • In this paper some of the main management control theories are reviewed and six dominating paradigms are identified. The identified management control paradigms are compared and analysed in relationship with the European Excellence Model (EEM) in order to investigate whether the EEM can be adopted as a management control model. Based on the analysis. advantages as well as disadvantages of the EEM as control model are discussed.

  • The authors investigated the spider fauna of Mt. Yebongsan from May 1994 to Aug. 1996. In this paper, 265 species from 21 genera, and 28 families were identified and compared with those from islands geographical with differing i.e., Is. Paikryung-do, Is. Chin-do, and Is. Ulrung-do distribution and climate. Spiders from 45 palaearctic regions(3.69%), 13 holarctic regions(1.06%), 4 oriental regions(0.32%) and 5 cosmopolitans(0.41%) are identified. Various methods were used for collecting specimens during the period including pitfall, beating, sweeping and looking up-down.

  • It is very important to increase defence capability rapidly against any surprise attack. This can be done by fast deployment of mobilization reserved resources. This paper is forcused on optimal allocation of special reserved resources. First of all, the location of special reserved resources is identified and then the location of combat and mobilization units and amount of requirement resources of each unit are identified. Finally, optimal allocation of the special reserved resources is obtained by Out of Kilter method.
