The mulberry variety, Jeonweon No. 1, has been cultivated in some parts of Ho-Nam District since the variety was selected at the Jeonbuk Provincial Silkworm Egg Production Station in the latter half of 1920s. However, the characteristics of the ariety have not been reported. Therefore, the cultivation experiment on the variety was carried out to investigate the characteristics of the variety at Jeonju and Suweon for four years from 1979 to 1982. 1. The mulberry variety, Jeonweon No. 1, belongs to the Morus alba L. and the sprouting stage is medium. 2. The branch growth of the variety was rather slow, however the number of branches was more and the posture of branches opened wide. 3. The rate of cold injury of shoot tips was a little high, but resistance to disease and the lodging of branches was weaker, compared with the Gaeryangbbong variety. 4. The annual yield of leaves of the variety per 10a was 1,474kg, 14% less than that of the Gaeryangbbong variety.

The $12^{th}$ rib syndrome is a disease that causes pain between the upper abdomen and the lower chest. It is assumed that the impinging on the nerves between the ribs causes pain in the lower chest, upper abdomen, and flank. A 74-year-old female patient visited a pain clinic complaining of pain in her back, and left chest wall at a 7 on the 0-10 Numeric Rating scale (NRS). She had a lateral fixation at T12-L2, 6 years earlier. After the operation, she had multiple osteoporotic compression fractures. When the spine was bent, the patient complained about a sharp pain in the left mid-axillary line and radiating pain toward the abdomen. On physical examination, the $10^{th}$ rib was not felt, and an image of the rib-cage confirmed that the left $10^{th}$ rib was severed. When applying pressure from the legs to the $9^{th}$ rib of the patient, pain was reproduced. Therefore, the patient was diagnosed with $9^{th}$ rib syndrome, and ultrasound-guided $9^{th}$ and $10^{th}$ intercostal nerve blocks were performed around the tips of the severed $10^{th}$ rib. In addition, local anesthetics with triamcinolone were administered into the muscles beneath the $9^{th}$ rib at the point of the greatest tenderness. The patient's pain was reduced to NRS 2 point. In this case, it is suspected that the patient had a partial resection of the left $10^{th}$ rib in the past, and subsequent compression fractures at T8 and T9 led to the deformation of the rib cage, causing the tip of the remaining $10^{th}$ rib to impinge on the $9^{th}$ intercostal nerves, causing pain.

Background and Purpose: Sybsun-points are located at the tips of all fingers, 0.1chon from the finger nails, totaling 10 points on both hands. These points have been used for emergency care, fainting, epilepsy, cerebrovascular accidents, hypertension, unconsciousness, high fever etc. The most common technique is bleeding with a needle at these points. Hypertension and fever are the main factors for stroke patients’progress. We investigated whether venesection at Sybsun-points has effects on blood pressure and body temperature in stroke patients. Materials and Methods: 79 stroke patients were enrolled in this study from 1 Jan. 1999 to 30 Sep. 1999. All of them were admitted in Kyunghee University, Hospital of Oriental Medicine. Among them, 62 patients were hypertensive people, 17 were normal. Among the hypertensive patients, 27 were stage 1,20 were stage 2, 15 were stage 3 by classification of JNC 1997. All of the hypertensive patients had been taking drugs, while the normal group did not. From 2pm to 3pm, every 30 minutes we checked patients' blood pressure and body temperature by 24ABPM and tympanic thermometer. After 30 minutes passed, we phlebotomized patients Sybsun-points with Samneung needle 2-3cc of blood. Right after the bleeding, we checked blood pressure and body temperature. After the bleeding, for the next hour and a half, we checked each patient’s blood pressure and body temperature every thirty minutes, or a total of three times. We compared the blood pressure and the body temperature before and after treatment(p<0.05). Results: 1. Venesection at Sybsun-points significantly decreased systolic blood pressure on stage 3 hypertensive patients(p<0.0l). 2. Venesection at Sybsun-points significantly decreased diastolic blood pressure on stage 3 hypertensive patients(p<0.05) 3. Venesection at Sybsun-points had no effect on the change of body temperature. Conclusions: Though further study is needed, our findings suggest that Venesection at Sybsun-points may alleviate hypertension in stroke patients.

To determine the critical level for optimum maturity of flue-cured tobacco leaves (KF118) at the stalk position from cutter to tips, the reflectance index using ground-based remote sensors and chlorophyll meter were investigated. The sensors estimated were Crop $Circle^{TM}$ (Holland Scientific), Green $Seeker^{TM}$ (Ntech Industries), Spectroradiometer (LICOR, LI-1800), Chlorophyll meter (SPAD502, Minolta), and Field $Scout^{TM}$ Chlorophyll meter (CM-1000, Spectrum). The L, a, b values and greenness for flue-cured leaf were measured and estimated for correlation with sensor's measurement of harvested leaf. On a reflectance curve of 340nm~1100 nm, the reflectance peaks on 550nm and 675 nm for the harvested leaf were lowered as change from light green to darker green. Darker green leaf harvested produced darker flue-cured leaf. The reflectance at 675 nm for flue-cured leaf decreased as greenness increased in the harvested leaf. This result means that the red edge band of 675 nm wavelength is related to the absorbance of chlorophyll for photosynthesis. The greenness of flue-cured leaf showed significantly positive correlation with the entire reflectance indexes for harvested leaf while the L value by colorimeter showed negative correlation with greenness of cured leaf. The critical level for optimum maturity of harvested leaf were less than 22, 135, and 0.43 for SPAD reading, CM-1000 reading, and gNDVI by Crop $Circle^{TM}$, respectively. Consequently, ground-based remote sensing providing a non-destructive real-time assessment of plant greenness could be a useful tool in the selection of optimum maturity of flue-cured tobacco leaves in relation to high quality of flue-cured tobacco.

Weak persistence of white clover (Trifolium repens L.) under continuous grazing management has been limited its availability in the mixture with grasses. The experiment was carried out to determine the effect of defoliation interval on the regrowth and morphological characters of the clover cultivars. Individual plants of Regal (large leaf), Grasslands Huia (medium-small leaf) and Aberystwyth S184 (small leaf) were grown in 15cm plastic pot containing a 1: 2: 1 soil:sand:Promix mixture for 55 days, and then clipped to remove all fully expanded leaves every 7, 14 or 28 days. For the analysis of the cultivar response, plants were sampled on the final harvest date(0), and 1, 3, 7, 14 and 28 days after the final harvest date. Harvested dry weight of all cultivars declined as defoliation interval was increased, and that of Regal was the highest compared to the other cultivars. During the regrowing period, increase of total plant dry weight was due to that of leaf and petiole dry weight, and that of Osceola was greater than the others. Although total leaf area and mean single leaf area were increased during the regrowing period, they were reduced with increased defoliation interval and those of Osceola were the greatest until 14-days regrowth. S184 possessed the most number of leaves and Osceola did the longest petiole since 14-days regrowth although the more defoliation, the less nunber of leaves per plant and the shorter petiole. Stolon length and growing tips of all cultivars increased steeply during regrowth, while they were decreased with increased defoliation interval and those of S184 were the highest. More frequent defoliation had detrimental effects on regrowth of white clover, although larger leaf type was productive but less persistent in a mixture with grasses than smaller leaf type.

Background: There have been many studies on the growth conditions of Zostera marina and Zostera japonica, but few studies have examined how spatial and temporal factors affect growth in established seagrass beds or the distribution range and shoot density. This study aims to clarify the factors that determine the temporal and spatial distribution of Zostera marina and Zostera japonica in the Seto Inland Sea east of Yamaguchi Prefecture. Methods: The study site is in Hiroshima Bay of the Seto Inland Sea, along the east coast of Yamaguchi Prefecture, Japan. We monitored by diving observation to confirm shoot density, presence or absence of both species and observed water temperature, salinity by sensor in study sites. Results: The frequency of occurrence of Zostera marina was high in all seasons, even in water depths of D.L. + 1 to -5 m ($80{\pm}34%$ to $89{\pm}19%$; mean ${\pm}$ standard deviation), but lower (as low as $43{\pm}34%$) near the breakwall, where datum level was 1 to 2 m, and it was further reduced in datum level -5 m and deeper. The frequency of occurrence of Zostera japonica was highest in water with a datum level of +1 to 0 m. However, in datum level of 0 m or deeper, it became lower as the water depth became deeper. Datum level +1 m to 0 m was an optimal water depth for both species. The frequency of occurrence and the shoot density of both species showed no negative correlation. In 2011, the daily mean water temperature was $10^{\circ}C$ or less on more days than in other years and the feeding damage by S. fuscescens in the study sites caused damage at the tips. Conclusions: We considered that the relationship between these species at the optimal water depth was not competitive, but due to differences in spatial distribution, Zostera marina and Zostera japonica do not influence each other due to temperature conditions and feeding damage and other environmental conditions. Zostera japonica required light intensity than Zostera marina, and the water depth played an important role in the distribution of both species.

This experiment was performed to investigate the flowering habit of sesame (Sesamum indicum L.). Sesame varieties tested could be classified into 8 different plant types by their morphological traits such as capsule shape, capsule setting habit and branching types among sesame gene pool of Crop Experiment Station, ORD. The first flower was appeared at the lowest node on main stem. Flowers were appeared progressively toward the tip of the main stem and also toward the tips of branches. The interval of flowering for a node was about one day, but 3 to 8 days for the flowers on the tips. Side flowers started at 4 to 5 nodes lower than those of center flower at the same day. Flowers were beared 2 by 1 node on the middle part of flower setting node (7-9) in mono capsule setting habit in spite of its normal is 1 by 1 node on the other nodes. Flowers were beared opposite direction on each node of stem and flowering toward the tip of main stem composed of cross shape between nodes and spiral, reverse of clockwise direction. We called this habit as cross spiral flowering order and cross spiral phyllotaxis. The first flower on branches was appeared when center flower on the 5th node of main stem began to flower. The branches produced at higher nodes on main stem showed larger flowering periods and more number of flowers than that at lower parts. BTB (Branch, Tricapsule, Bicarpels, 4 Loculi) type showed three capsule setting habits and same flowering period both on main stem and branches while BTQ (Branch, Tricapsule, Quadricarpels, 8 Loculi) type showed three capsule setting habit on main stem and mono-capsule setting habit on branches. In BTQ type, the period of flowering was much shorter on branches than on main stem. Branching type was considered more promising than non branching type for the breeding of early maturing high yielding variety because branching type has the advantage of bearing a lot of flowers in comparatively short flowering period.

Purpose In a cyclosporine experiment using a robotic liquid handing system has found a deviation of its standard curve and low reproducibility of patients's results. The difference of the test is that methanol is mixed with samples and the extractions are used for the test. Therefore, we assumed that the abnormal test results came from using methanol and conducted this test. In a manual of a robotic liquid handling system mentions that we can choose several setting parameters depending on the viscosity of the liquids being used, the size of the sampling tips and the motor speeds that you elect to use but there's no exact order. This study was undertaken to confirm pipetting ability depending on types of liquids and investigate proper setting parameters for the optimum dispensing ability. Materials and Methods 4types of liquids(water, serum, methanol, PEG 6000(25%)) and $TSH^{125}I$ tracer(515 kBq) are used to confirm pipetting ability. 29 specimens for Cyclosporine test are used to compare results. Prepare 8 plastic tubes for each of the liquids and with multi pipette $400{\mu}l$ of each liquid is dispensed to 8 tubes and $100{\mu}l$ of $TSH^{125}I$ tracer are dispensed to all of the tubes. From the prepared samples, $100{\mu}l$ of liquids are dispensed using a robotic liquid handing system, counted and calculated its CV(%) depending on types of liquids. And then by adjusting several setting parameters(air gap, dispense time, delay time) the change of the CV(%)are calcutated and finds optimum setting parameters. 29 specimens are tested with 3 methods. The first(A) is manual method and the second(B) is used robotic liquid handling system with existing parameters. The third(C) is used robotic liquid handling system with adjusted parameters. Pipetting ability depending on types of liquids is assessed with CV(%). On the basis of (A), patients's test results are compared (A)and(B), (A)and(C) and they are assessed with %RE(%Relative error) and %Diff(%Difference). Results The CV(%) of the CPM depending on liquid types were water 0.88, serum 0.95, methanol 10.22 and PEG 0.68. As expected dispensing of methanol using a liquid handling system was the problem and others were good. The methanol's dispensing were conducted by adjusting several setting parameters. When transport air gap 0 was adjusted to 2 and 5, CV(%) were 20.16, 12.54 and when system air gap 0 was adjusted to 2 and 5, CV(%) were 8.94, 1.36. When adjusted to system air gap 2, transport air gap 2 was 12.96 and adjusted to system air gap 5, Transport air gap 5 was 1.33. When dispense speed was adjusted 300 to 100, CV(%) was 13.32 and when dispense delay was adjusted 200 to 100 was 13.55. When compared (B) to (A), the result increased 99.44% and %RE was 93.59%. When compared (C-system air gap was adjusted 0 to 5) to (A), the result increased 6.75% and %RE was 5.10%. Conclusion Adjusting speed and delay time of aspiration and dispense was meaningless but changing system air gap was effective. By adjusting several parameters proper value was found and it affected the practical result of the experiment. To optimize the system active efforts are needed through the test and in case of dispensing new types of liquids proper test is required to check the liquid is suitable for using the equipment.

Availability of white clover (Trifolium repens L.) has been limited due to its poor introduction to swards and lack of persistence under improper grazing management. This experiment was conducted to determine the effects of initial defoliation stage and defoliation interval on the growth of white clover varieties. Individual plants of Regal (large leaf), Louisiana S.1 (medium-large leaf), Grasslands Huia (medium-small leaf) and S184 (small leaf) were grown in containers (4.5 $\times$ 13.5 cm) containing a 1:2:1 soil:sand:Promix until reaching to the stage of 1, 4, or 8 trifoliolates, and then clipped to remove all fully expanded leaves every 7 or 28 days (d). For analysis of morphological parameters, plants were sampled on the final harvest date (0 d), and 7, 14, 21, and 28 d after the final harvest date. Harvested dry weight (dw) of all varieties declined as defoliation interval declined or initial defoliation was made earlier. That of Regal was the highest as initial defoliation was delayed. On the 7 d regrowth shoot and root dw were increased as initial defoliation was delayed or interval lengthened, whereas on the 28 d regrowth the trend was alleviated. Root dw and biomass of Regal were higher than the other varieties during the whole regrowing period, when the increase of biomass resulted from that of shoot dw. Leaf areas and petiole lengths of all varieties declined under 7 d defoliation interval. The area and the length declined with earlier initial defoliation on the 7 d regrowth but not on the 28 d regrowth. Stolon length and growing tips of S184 were the highest and increased more steeply during regrowth, while those of Regal were the lowest and did slightly. It is concluded that the continuous defoliation and the first defoliation at earlier growth stage have detrimental effects on growth of white clover, although larger leaf types are more productive but less persistent in a sward than smaller leaf types.
