본 논문에서는 임의 위치에서 기존의 무선 통신 시스템에서 사용되는 주파수 대역이 전체 스펙트럼 자원에 존재하는 비율로서 정의되는 스펙트럼 사용 계수를 이용하여 스펙트럼 사용량을 정량적으로 나타내는 방법을 제안하였다. 기존 무선 시스템과 동일 공간에서 스펙트럼을 사용하기 위해 기존 시스템의 안테나 패턴과 송신 전력 등의 함수로 스펙트럼 사용 계수를 나타내었고, 계산된 결과를 서울 지역의 실제 고정 서비스 무선국에 적용하여 스펙트럼 사용량을 계산하였다. 본 논문에서 나타낸 스펙트럼 사용 계수를 이용하면 새로운 무선 시스템을 동일 공간에서 사용하고자 하는 경우 사용되는 스펙트럼을 정량적으로 나타낼 수 있기 때문에, 스펙트럼이 사용되지 않는 공간을 단순한 빈 공간이 아닌 정량적으로 나타낼 수 있게 되어 스펙트럼 공간을 효율적으로 사용할 수 있다. In this paper, spectrum use factor as the ratio between used spectrum bandwidth by the existing system and total spectrum resources at specific locations was derived and calculated. Spectrum use factor was also presented as a function of antenna patterns and transmitter power of existing systems. Real spectrum use factor was calculated for fixed radio station as a validity of this paper. With the results of this paper, we can use the spectrum more efficiently because the white space of spectrum space is replaced by the quantificated spectrum space.

Background : There was seldom study about method that diagnose 8 Constitution beside method of pulse diagnosis in 8 Constitution Medicine. Objectives : This study is to make out 8 Constitution Medicine Diagnosis Expert System Development used CBR(Case based Reasoning). Methods : First, at case base construction process we constructed case base for CBR embodiment because gathering 925 cases all to patient who constitution is verified, and second, at study model establishment process superior expert system development by purpose CBR of reasoning process dividing fundamental type CBR that spend basis data value and expert type CBR that reflect weight in basis ⅠⅡⅢ data value according to advice expert opinion, and third, system embodiment process explained about way to give process and weight that diagnose constitution through Nearest Neighbor Method sampling process of CBR techniques, and fourth, at system estimation process we selected superior CBR model because comparing and estimate the diagnosis rate of expert system with fundamental type system (GECBR) model and expert typeⅠⅡⅢ CBR system (AVCBR, AACBR, AGCBR) model that reflect expert opinion in fundamental type system. GECBR and AGCBR chose on superior study model. Through such 4 study process, we developed 8 constitution diagnosis expert system lastly. Results : 1. When we select GECBR that is fundamental type by reasoning system, diagnosis rate 78.91% of 8 constitution diagnosis expert system is expected, and the constitution diagnosis rate Hepatonia 90.4%, Cholecystonia 63.0%, Pancreotonia 91.1%, Gastrotonia 0%, Pulmotonia 71.2%, Colonotonia 74.4%, Renotonia 37.5%, Vesicotonia 67.1% expect. 2. When we select AGCBR that is expert type Ⅲ by reasoning system, diagnosis rate 77.51% of 8 constitution diagnosis expert system is expected, and the constitution diagnosis rate Hepatonia 93.4%, Cholecystonia 58.5%, Pancreotonia 91.1%, Gastrotonia 0%, Pulmotonia 73.1%, Colonotonia 64.4%, Renotonia 41.7%, Vesicotonia 72.2% expect. Conclusion : Based on this study, 8 constitution diagnosis expert system may give help to diagnose 8 constitution, and it is going to utilize as objective estimation tool of 8 constitution diagnosis, and further study for 8 Constitution Medicine Diagnosis Expert System Development used CBR(Case based Reasoning) is needed to supplement this study.

참죽나무 순채 조기생산을 위하여 하우스와 노지재배에서 생산된 잎의 무기성분을 분석한 결과는 다음과 같다. 참죽나무 순채의 생장속도는 노지에 비하여 하우스 재배에서 다소 빠른 경향이었고, 정아의 경우 초장, 가지수 등 생육과 생체중, 엽록소 함량 등 품질은 노지와 하우스재배 처리 간 큰 차이가 없었다. 참죽나무순채의 색도(a값)는 측아보다는 정아에서 적색도가 다소 높았으나 하우스와 노지재배 간에는 차이가 거의 없었다. 참죽나무 정아 및 측아의 pH는 5.7~6.2 정도였고 N 함량은 측아의 평균 500.5㎎ · ㎏<SUP>?1</SUP>에 비해 정아에서 3.1배 많았고, 노지재배(1,430㎎ · ㎏<SUP>?1</SUP>)보다는 하우스 재배에서 1.2배 많았다. P, Ca, Mg 및 Fe 함량도 노지재배에 비하여 하우스 재배에서 유의성 있게 높았는데, P는 1.1배, Ca는 1.7배, Mg는 2.0배, Fe는 2.3배 정도 많았으나 K 함량은 하우스 재배의 2.94㎎ · ㎏<SUP>?</SUP>1에 비하여 노지재배에서 1.6배 많았다. Ascorbic acid 함량은 하우스 측아에서 1,461㎎ · ㎏<SUP>?1</SUP>으로 가장 높았고 노지 측아, 노지 정아, 하우스 정아 순이었다. 이상의 결과를 종합하면 고품질 참죽나무 순채생산을 위해서 하우스 재배가 필요한것으로 생각된다. In this study, we investigated the changes of growth characteristics, mineral and chlorophyll content of young leafy vegetable of Chinese toon grown under greenhouse and open fields. Results showed that growth of young leafy vegetable of Chinese toon was somewhat accelerated in greenhouse compared to the open field. In case of apical bud growth, several parameters such as plant height, number of branch, fresh weight and chlorophyll content showed similar tendency in both greenhouse and open field. In the changes of minerals, N content in apical buds recorded significant increase to 3.1 times compared to that of later buds. Its content was 1.2 times higher in greenhouse than that of open field. Mineral contents including P, Ca, Mg and Fe were significantly increased in greenhouse. Highest ascorbic acid content was observed in lateral buds grown in greenhouse and then it was followed such as lateral bud in open field, apical bud in open field, and apical bud in greenhouse, in turn. These results indicate that greenhouse culture could be applicable to new culture in order to produce young leafy vegetable of Chinese toon with high quality.

Background: There was seldom study about method that estimate expertness of pulse diagnosis in 8 Constitution Medicine in spite of the diagnostician importance in 8 Constitution Medicine Objectives: This study is to evaluate diagnostician`s consistency and accuracy about pulse diagnosis in 8 Constitution Medicine using Gage R&R study. Methods: The subjects were comprised of 28 volunteers. Among theme, 3 diagnosticians and 10 participants were chosen through questionnaire. Diagnosticians diagnosed participant`s Constitution by pulse diagnosis in 8 Constitution Medicine with hiding their eyes by eyepatch. MINITAB statistical software(ver. 13.20) was used for statistical analysis: Attribute Gage R&R study was used to verify the results. Results: 1. In the measurements of consistency, diagnostician b(agreement=80%, Value of k=0.8276) was very good, diagnostician a(agreement=70%, Value of k=0.7465) was good, and diagnostician c(agreement=50%, Value of k=0.5365) was moderate. 2. In the measurements of accuracy, diagnostician b(agreement =70%, Value of k=0.6812) was good, diagnostician a(agreement=60%, Value of k=0.6414) was good, and diagno-stician c(agreement=0%, Value of k=-0.1000) was poor. 3. In confidence of diagnosis, diagnostician c was 75%, diagnostician a was 70%, and diagno-stician b was 64%. Conclusion: The results suggest that diagnostician`s consistency and accuracy about pulse diagnosis in 8 Constitution Medicine can be evaluated by Gage R&R study. Further study is needed for estimation method of pulse diagnosis in 8 Constitution Medicine.
