Objectives : The original plant species of Schisandrae Fructus (O-mi-ja) is prescribed as Schisandra chinensis $B_{AILL.}$, in Korea, but S. chinensis $B_{AILL.}$ and S. sphenanthera $R_{EHD.}$ et $W_{ILS.}$ in China. Moreover, fruit of several other species in genus Schisandra also have been used as the same herbal medicines. To develop a reliable method for correct identification of Schisandrae Fructus and to evaluate the phylogenetic relationship of S. chinensis and its related species, we analyzed internal transcribed spacer (ITS) sequences of nuclear ribosomal DNA (nrDNA). Methods : Twenty-four plant samples of three Schisandra species and one Kadsura species, S. chinensis $B_{AILL.}$, S. spenanthera $R_{EHD.}$ et $W_{ILS.}$, S. nigra $M_{ax.}$ and Kadsura japonica $D_{UNAL}$ were collected from each different native habitate and farm in Korea and China. The nrDNA-ITS region of each samples were amplified using ITS1 and ITS4 primer and nucleotide sequences were determined after sub-cloning into the pGEM-Teasy vector. Authentic marker nucleotides were estimated by the analysis of ClastalW based on the entire nrDNA-ITS sequence. Results : In comparative analysis of the nrDNA-ITS sequences, we found specific nucleotide sequences including indels (insertions and deletions) and substitutions to distinguish C. chinensis, S. spenanthera, S. nigra, and K. japonica. These sequence differences at corresponding positions are avaliable nucleotide markers to determine the botanical origin of O-mi-ja. Moreover, we evaluated the phylogenetic relationship of four plant species by the analysis of nrDNA-ITS sequences. Conclusions : These marker nucleotides would be useful to identify the official herbal medicines by the providing of definitive information that can identify each plant species and distinguish it from unauthentic adulterants for O-mi-ja.

건강한 성인 83명을 무작위로 선정하여 실시한 신경전도속도 검사에서 다음과 같은 결과를 얻었다. 1) 상지의 정중신경에서는 운동신경의 TL이 3.0-4.2msec 이고, MNCV는 각각 52.1-70.3m/sec(W-E), 44.6-71.0m/sec(E-Ax), 56.6-70.8m/sec(W-E), 50.5-75.1m/sec(E-Ax)이며, CNAP의 진폭은 $6.5-46.1{\mu}V$였다. 2) 척골신경에서는 운동신경의 TL이 2.4-3.4msec이고, MNCV는 각각 54.6-72.8m/sec(W-E), 41.1-64.9m/sec(E-Ax)1987년 3월부터 동년 12월까지 영남대학교 의과대학 부속병원에서 시행된 개심술마취 40례를 대상으로 저체온 체외순환시 저체온상태의 동맥혈과 정맥혈을 동시에 각각 채혈하여 $37^{\circ}C$ 혈액가스분석기로 측정한 비보정치와 환자의 실제 저체온으로 보정한 보정치를 각각 얻어 이를 비교하여 보았던 바 보정치가 비보정치에 비하여 pH는 높았고 이산화탄소분압과 산소분압은 낮았으며 $HCO_{3^-}$, 염기과잉, 이산화탄소분압 및 산소포화도는 온도보정에 영향을 받지 않았다. 이상의 결과로 미루어 보아 저체온상태의 혈액가스분석시 pH와 이산화탄소분압에 대한 온도보정의 영향은 크며, 저온상태에서의 pH 중심점이동과 산염기가 환자상태에 미치는 영향을 고려한다면 환자실제 저체온으로의 온도보정은 필요치 않을 것 같으며 오히려 $37^{\circ}C$ 비보정치로 판독하여 환자상태를 판정하는 것이 임상적으로는 더 타당한 방법이라 사료된다.

This paper is based on the 36 wild Japanese quails which migrated to and settled in the Weishan Lake area. The gene frequency of 10 loci encoding the enzymes in viscera and muscle was detected. After collecting the same data about 20 quail colonies in China and other countries, it clusters the 21 quail populations by fuzzy cluster analysis. The study indicates that the wild Japanese quail in the Weishan Lake area is closer to domestic quail for phylogenetic system than wild Japanese quails in Japanese Islands. The paper supports the thesis that the quail domestication area should be further studied.

As a primary step in studying the effects of the netting porosity on the net-shape in the four-seam trawling net, a series of experiments were performed changing the porosity of each panel, with the simplified mo:iel of the bag net made of porous vinyl film and that ma:ie of net webbing. These models were suspended horizontally in circularly flowing water, with two pairs of susp~nding threais to four points of symetry at the border of the bag mouth in place of both wing nets. And then, the section shape of the bag mouth photographed and the tensions on both pairs of suspending threads were measured with two load cells in circularly flowing water. From the results, the auther estimated an experimental equation from the relationship between the porosity of each panel in the bag net and the section shape of the bag mouth, h/w=k (l-Pr_u/lPr_s)

Alfalfa (Medicago sativa L) is a high-quality forage for ruminants and the main stem is the dominant morphological component contributing to the forage nutritive value in mature alfalfa forage. Shearing force, a fracturing property of plant stem, is an important indictor of forage value. The objectives of this study were to investigate the effects of morphological characteristic on shearing force, the relationship between shearing force and chemical composition, and the relationship between shearing force and in situ digestibility of alfalfa stem. The results showed that linear density (weight per unit length of stem) was more important than chemical composition in affecting shearing force. There was a positive relationship between lignin content and shearing force (r = 0.78). Correlations were not found between shearing force and other chemical components such as neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose and hemicelluloses. In situ digestibility (of dry matter and NDF) was related to shearing force. A negative correlation was found between shearing force and dry matter (DM) digestibility (r = -0.70), and there was also a negative correlation between shearing force and NDF digestibility (r = -0.87). When shearing force was standardized for stem diameter or stem linear density, the relationship between shearing force and digestibility was consistent regardless of stem diameter and stem linear density. Shearing force was significantly correlated with lignin content and in situ digestibility (of DM and NDF), and was a more direct indicator for estimating forage nutritive value related to animal performance, so it can be used to predict the forage value of alfalfa.

The purpose of this study is to establish more rational and practical planning theory for amusement park. It analyze and consider the fluctuation of people who come and use the Tong-Ch'on amusement park. The results drawn from this reserch work are as follows; 1. The main visitors of the Tong-Ch'on amusement park are students in their twenties and thirties, and people whose incomes are below 300,000 Won a month. The purpose of visit is for a rest rather than for amusement and user prefer summer, while the user is so rare in wintertime. Those phenomena observed are somewhat different from the real purpose of a amusement park which is on purpose to make profits by offering entertainments to the users. So planner should pay attention to the three points. They are varieties, seasonable diversification and fantastic character of facilties, in the amusement park. 2. The access time of the Tong-Ch'on amusement park was 41 minutes, the use frequency was 4 times a year and resident time was 164 minutes. The relationship of the three factors are as follows; log Y(F) =1.7832-0.0277(A.T) R$^2$=0.75 Y(R. F)=31.8885+3.3217(A.T) R$^2$=0.53 Y(R. T)=224.8959-87.8309 1og(F) R$^2$=0.38 F;Use frequency(time/year) A.T;Access Time(minute) R.T;Resident Time(minute) 3. In the choice of space, there were much differences according to tole user's age, job, degree of education, companion type and purpose of use. 4. There are considerable correlation between use fluctuation and some factors. The factors are season(summer, winter) as a time, temperature, cloud amount, duration of sunshine, weather(rainy-day) as a climate and a day of the week(weekday, holiday) as a social system. The important variables are temperature, cloud amount, duration of sunshine and a day of the week(weekday, holiday) to estimate the user of amusementpark. 5. 1 can reduce the following two types of regression models. 1) log$\sub$e/ Y1 = 6.9114 + 0.l135 TEM + 0.00002 SUN -0.4068W1 + 0.4316 W3 (R$^2$= 0.94) 2) log$\sub$e/ Y2 = 7.2069 + 0.l177 TEM - 0.0990 CLO + 0.4880 W3 (R$^2$=0.95) Y; Number of User TEM; Temperature CLO; Amount of cloud SUN; Duration of Sunshine W1; Weekday W3; Holiday Those model is in order to estimate the user for management of Tong-Ch'on amusement park and use on the computation of facility sloe for reconstruction. Besides the amusement park, city park and outdoor recreation area could estimate of user through this method. But, I am not sure about the regression models because I did not apply the regression models to the other amusement park, city Park or outdoor recreation area. Therefore, I think that this problem needs to be studied on in the future.

In this study, among the W-S-R(Wiper-Signal-Rainfall) relationship methods used to produce sensor-based rain information in real time, we sought to produce actual rainfall information by applying machine learning techniques to account for the effects of wiper operation. To this end, we used the gradient descent and threshold map methods for pre-processing the cumulative value of the difference before and after wiper operation by utilizing four sensitive channels for optical sensors which collected rain sensor data produced by five rain conditions in indoor artificial rainfall experiments. These methods produced rainfall information by calculating the average value of the threshold according to the rainfall conditions and channels, creating a threshold map corresponding to the 4 (channel) × 5 (considering rainfall information) grid and applying Optima Rainfall Intensity among the big data processing techniques. To verify these proposed results, the application was evaluated by comparing rainfall observations.
