In this study, growth rates and enzyme activities of mushroom mycelium were investigated in each cereals. Cultivation on hulled barley resulted in slightly faster mycelial growth as compared to other substrates. Enzyme activities were measured in different periods. In result, α-amylase activity was higher in Pleurotus ostreatus and Phellinus linteus cultured cereals, whereas β-amylase activity was higher in Pleurotus ostreatus and Fomitella fraxinea cultured. Protease level did not affect kinds of cereal except Phellinus linteus. The color values lightness decrease by Basidiomycetes cultivation and redness and yellowness increased. 본 연구는 곡류별 버섯 균사체의 성장률과 효소활성을 측정하였다. 현맥 배양물이 다른 곡류와 비교했을때 균사체 성장 속도가 빨랐다. 효소 활성은 기간별로 측정하였으며 그 결과, α -amylase 효소 활성은 느타리와 상황버섯균이 우수하였으며, β -amylase활성은 느타리와 장수버섯균이 우수하였다. Protease활성은 상황버섯균을 제외하고는 곡물에 관계없이 비교적 고른 생산을 보였다. 담자균 배양에 의해서 명도는 감소하고 적색도와 황색도가 증가하였다.

MLS(Microwave Landing System)는 어떤 활주로 상황에서도 기종에 관계없이 계기착륙이 필요한 항법정보를 정확하고 신롸성있는 상태에서 넓은 운용범위를 갖게되는 시스템으로서 ILS보다 장비기술 및 운용면에서 우수한 것으로 입증되었으며, 공항의 장애물과 악지형의 영향에 따라 유도특성이 방해받더라도 시스템의 가용성에는 제한이 없도록한 특징이 있다. 본 논문에서는 기존의 ISL의 접근절차로서는 불가능했던 비표준 지형과 평행 활주로에서 MSL를 이용한 접근 유도시 활주로 중심선에 대한 접근 오차 한계를 계산하고 기준 활주로와 평행 활주로 각각에 대한 접근유도시 거리오차를 산출하여 MSL를 이용한 정밀 접근유도 상태를 검토하였다. 그 결과 MSL는 비표준 지형 및 평행 활주로에서도 5NM이내의 거리에서는 접근오차가 0.1%(0.16NM)이내를 유지하여 ICAO 기준을 만족함으로써 규정상의 접근유도가 가능함을 알수 있었다. The MLS was followed by definition of a signal-in-space having the accuracy, reliability and coverage to aeronautics needs for all type of aircraft at all runway suitable for terminal instrument procedures. MLS has been demonstrated to be superior to ILS from both technical and operational capabilities. Even at runway where ground terrain and airport obstacles prevent standard split-site installations, the availability of MLS will not be limited. In this thesis, the range error and limitted error bound of a computed centerline approach is derived and identified in order to solve the problems of percision approach guidence at non-standard sitin gand parallel runway. As the result, it is known that the MLS is able to approach guidence with 0.1%(0.16NM) limited range error at non-standard siting and parallel runway within 5NM.

This study is to analyze the courses of building of and space characteristic of Dokrakdang, one of the houses in Chosun Dynasty. Specially, to analyze the space configuration of the Dokrakdang which was built by Hoejae , Lee UnJuk. The space configuration of Dokrakdang can be summarized as the followings: First, The courses of building it were made up of by several stages through long time. In other words, Dokrakdang is prior decision factor that should consider at enlargement of other domain buildings, and arrangement of building and fence and exterior space of Madang are used on active domain limitation constituent. Second, early Kyejeung which is father's pavilion and Jeung-Hye-Sa, and Hoejae's rustication by political retirement are the background of Dokrakdang construction and became important factors to determine building's characteristic. Accommodation of such various purpose gave completion and holistic to each part of it through closing and opening, connection and disconnection. Third, Exterior space of the individualized Madang was reinforced immanence of space by control of moving line by entrance position, and had suitable component ratio between the building and the fence for each domain. Fourth, by presuming original design of Anchae, Dokrakdang contains YouGang Lee's who is Hoejae's family architectural characteristics than Walsung Son's who built Seobaikdang and kwankajeung.

Prediction of thrapeutic response to radioiodine in Graves' disease is poorly understood. Although thyrotropin binding inhibitor immunoglobulin(TBII) level is a strong index for relapse after antithyroid drug medication, conflicting results are reported regarding its prognostic significance in Graves' disease treated with RAI. This study is dengned to evaluate possible relationship between post-treatment hypothyroidism and TBII in Graves' disease treated with RAI. Fourty two patient with Graves' disease after radioiodine treatment were studied retrospectively. The subject were divided into hypothyroid group and euthyroid or hyperthyroid group. We evaluated the association of hypothyroidism and TBII with radioiodine treatment dose. The mean age of hypothyroid group was 48±11 years and euthyroid or hyperthyroid group was 47±12 years. There was no difference in two groups. And there was no significant difference in post- treatment TBII between two groups(49.9±28.5%, 29.9±14.3%, p-value >0.05). The treatment-dose had no influence on post-treatment thyroid state. Euthyroid or hyperthyroid group was done with 13.6±6.9mCi and hypothyroid group was 17.0±10.4mCi(p-value > 0.05). TBII had no prognostic significance on long-term hypothyrodism in Graves' disease treated with radioiodine. And, treatment-dose had no influence on post-treatment thyroid state.

The collection efficiency of the Lapple's standard-type cyclone separator was determined in order to investigate the effects of the particle size of the dust samples, the dust loading, and the air inlet velocity to the cyclone under the ambient conditions. The experimental conditions are in the following ranges; the air inlet velocity; 5 to 14.7 m/s, the particle sizes of the mono-dispersed system; 14 to 280 ㎛, the dust loading; 17.8 to 58.6 g/㎥, respectively. The collection efficiencies determined were compared with those predicted by the semi-empirical equations proposed earlier by Strauss (³) and by Licht et al, (⁴) and those are shown to be increased, as the particle size of the sample dusts and the air inlet velocity increase, respectively. However, the effect of the dust loading in the air could not be recognized, but slightly increased. For the poly-dispersed particulate samples, having a wide particle size distribution, the grade or separation efficiency curve was experimentally determined to specify more exactly the cyclone separation performance, and the result was discussed with the statistical analysis previously worked by Herrmann.(??)

Man has produced various of technical products to more and enrich his life and make it convenient. The technical culture has been kept developing up to today, with the infinite efforts, for the purpose of meeting these natural wished of mankind. The treces which the race has trod, whichever races their countries consist of, have the traditions descending from deep roots through customs and beliefs in themselves. In the heart of these traditions, there was a technical culture of wooden technical arts which was glorious in the Chosun Dynasty's era. But as the period elapsed Dynasties changed their hands it must in turn be great pities that in accordance to the changes of the period the glorious cultural heritages should be extinguished and destroyed. On theis account, I would seek to search for 'the Korean characteristic', the flaver and beauty of Korea so that we might rediscover ours in the disappearing traditions. This thesis shows that not only the kind and use of the wooden technical arts in the Chosun Dynasty's era but especially the kind of desighs, the function and name of the metal-ornament got analysed, and that in carefully studying and examining the the designs, forms and function of hinges I would appreciate the excellent tradition and wisdom of our nation borne in the hinges. As the metal-ornament bears the human in erest of a nation most naturally and plainly, as the wooden technical arts do well represent peculiar characteristics thickening the local colors, the purpose of this thesis on the metal-ornament is to establish the function and aesthestics of the metal-ornament attached in the wooden technical arts, to reanalyse our tradition on the basis of modem views and to present the modem metal-ornament, especially the direction of hinge-designs. Therefore, the result of these researches is expected to be the available data presenting the direction of the designs and the imporvements of the modern metal-ornament.
