This study inverstigates growing seedling of onion for 91 farmhouses at Muan, Hampyeong and Sinan which are major areas of production from Jan. to Apr., 1994 to enhance the research effect of onion and then the following results are obtained. Over 60% of the farmhouses have cultured onion continuously over 11years. Early mature variety cultured is over 9 varieties and among them Kinkyu variety is cultured most frequently. Late mature variety is over 13 and Changyongdaego, Bonganwhang and Chunjudaego varieties are cultured most. Most of the farmhouses used seeds less than 6 dl at small area less than $40m^2$ and especially in the case of early variety ,they purchased it at seed stores with 15,000-20,000 won/dl and sowed them with broadcasting method. Amount of fertilizer level of onion seed is ranged from nonfertilizer level to $16.8g/m^ and most of the farmhouses employ molding after seeding with straw and compost and they did not use thinning. Irrigation is performed by 1-4 times before sprouting of onion seed and most of the farmhouses transplant long nursery plant over 46 days hand weeding is used.

This paper describes a SVPWM overmodulation scheme of NPC type three-level inverter for traction drives which extends the modulation index from MI=0.907 to unity. SVPWM strategy is organized by two operation modes of under-modulation and over-modulation. The switching states under the under-modulation modes are determined by dividing them with two linear regions and one hybrid region the same as the conventional three-level inverter. On the other hand, under the over-modulation mode, they are generated by doing it with two over-modulation regions the same as the conventional over-modulation strategy of a two level inverter. Following the description of over-modulation scheme of a three-level inverter, the system description of a vector controlled induction motor for traction drives has been discussed. Finally, the validity of the proposed modulation algorithm has been verified through simulation and experimental results.

Traditionally, surface energy fluxes are obtained by model simulations or empirical equations with auxiliary meteorological data. These methods may not effectively represent the surface heat fluxes in a regional scale due to scene variability. On the other hand, remote sensing has the advantage to acquire data of a large area in an instantaneous view. The remotely sensed data can be further used to retrieve surface radiation and heat fluxes over a large area. In this study, the airborne and satellite images in conjunction with meteorological data and ground observations were used to estimate the surface heat fluxes over Taiwan's Chaiyi Plain. The results indicate that surface heat fluxes can be properly determined from both airborne and satellite images. The correlation coefficient of surface heat fluxes with in situ corresponding observations is over 0.60. We also observe that the remotely sensed data can efficiently provide a long term monitoring of surface heat fluxes over Taiwan's Chaiyi Plain.

LSM(Least-Squares Method) has inherent limitation that precise system identification over wide frequency band is difficult especially at low frequency hand. In this paper we propose to use decimation, a spectrum analysis method widely used in signal processing. The merits of decimation are the flexibility of selection of the frequency hand concerned and the function of LPF(Low Pass Filter). In this paper, frequency-domain is divided into separate frequency bands which will be combined into full frequency-domain by using MDM(Multiple Decimation Method). In this way, free selection of sampling frequency for each hand is possible and the low frequency oscillation modes of LSM are avoided.

During the 8 months from October 1985 to May 1986, the survey was performed on 211 leprosy patients over fifty years old, settled in the four villages of Iksan county, North of Chulla province. In that obserbation, we investigated the frequency and the degree of impairments according to sex, age, and anatomical location by the 'guides to the evaluation of permanent impairment'. The noticeable findings were made as follows: 1) Frequency of impairment by anatomical location was significantly higher in hand than eye and foot (p<0.01). 2) Frequency of impairment was significantly increased in eye according as age increase (p<0.01). 3) The degree of impairments of all patients was the highest in hand as 28.7%. 4) By the kinds of impairment, the flextion and the amputation were most common in hand and foot, and loss of central vision was common symptom in eye. 5) The degree of impairments of 211 leprosy patients was shown as 44.1% and increased according as age increase.

A simple efficient method of spotting and recognizing hand gestures in video is presented using a network of hidden Markov models and dynamic programming search algorithm. The description starts from designing a set of isolated trajectory models which are stochastic and robust enough to characterize highly variable patterns like human motion, handwriting, and speech. Those models are interconnected to form a single big network termed a spotting network or a spotter that models a continuous stream of gestures and non-gestures as well. The inference over the model is based on dynamic programming. The proposed model is highly efficient and can readily be extended to a variety of recurrent pattern recognition tasks. The test result without any engineering has shown the potential for practical application. At the end of the paper we add some related experimental result that has been obtained using a different model - dynamic Bayesian network - which is also a type of stochastic model.

Acupuncture and acupressure apply needles or pressure to anatomical points for therapeutic benefit. The over 350 mapped acupuncture points in the human body can each treat various conditions, but anatomical variations make precisely locating these acupoints difficult. We propose a computer vision technique using the real-time hand and face tracking capabilities of the MediaPipe framework to identify acupoint locations. Our model detects anatomical facial and hand landmarks, and then maps these to corresponding acupoint regions. In summary, our proposed model facilitates precise acupoint localization for self-treatment and enhances practitioners' abilities to deliver targeted acupuncture and acupressure therapies.

Article 67 of CISG which provides for the passing of risk of loss of the goods applies to the contract of sale involving carriage of the goods. The risk here is in nature the price risk. Under Article 67(1), if the seller is bound to hand the goods over to a carrier at a particular place, the risk passes to the buyer when the goods are handed over to the carrier at that place; if the seller is not bound to hand them over at a particular place, the risk passes to the buyer when the goods are handed over to the carrier. In these cases, the risk passes even though the seller duly retains documents controlling the disposition of the goods. Article 69 of CISG applies to the contract of sale that does not involve carriage of the goods. Under Article 69(1) which covers the situation that the buyer is bound to take over the goods at the place of business of the seller, the risk passes when the buyer takes over the goods, however if the buyer does not take over the goods in due time, the risk passes at the time when the goods are placed at the buyer's disposal and he commits a breach of contract by failing to take delivery. Under Article 69(2) which covers the situation that the buyer is bound to take over the goods at a place (including his own place of business) other than the place of business of the seller, the risk passes when delivery is due and the buyer is aware of the fact that the goods are placed at his disposal at that place. Under these provisions of CISG, this study suggests what should be the definition of the contract of sale involving carriage of the goods. This study goes further to looks into what should be the concepts of the handing over of the goods by the seller to the carrier, the taking over of the goods by the buyer and the placing the goods at the buyer's disposal by the seller. This study may, we hope, provide a guidance for clearer understanding of the exact time of passing of risk under CISG.

Purpose: This study examined the improved sensory, hand function, postural balance and activities of daily living (ADL) through somatosensory stimulation, such as the facilitation of functional reaching and tactile, proprioceptive stimulus of the upper limb (UL) and hand. Methods: Seventeen stroke patients having problems with motor and somatosensory deficits were selected in Bobath Memorial Hospital adult rehabilitation center. The patients were divided into two groups; the sensorimotor deficit group (SMDG) and motor deficit group (MDG). Somatosensory stimulation on the UL, physical therapy and occupational therapy were carried out three times a week over a six week these treatments were performed in both group period. To compare each group, the following assessment tools were used: such as tactile detection thresholds (TDT), two point discrimination on the affected side (TPDas), unaffected side (TPDus) stereognosis (ST) manual function test, hand function on the affected side (HFas) and unaffected side (HFus), Postural Assessment Scale for Stroke (PASS) and Korean version Modified Barthel Index (K-MBI). Results: In the SMDG, somatosensory stimulation on the UL was statistically important for TDT, TPDas, TPDus (except for the thener), ST, hand function on HFas, on HFus, PASS length of displacement with foam (LDFSEO), and K-MBI. In the MDG, somatosensory stimulation on the UL was important for TDT, TPDas, TPDus (except index finger) length of displacement with the eyes open, LDFSEO, HFas, HFus, PASS and K-MBI. In addition, there was a significant difference in the PASS between SMDG and MDG. Conclusion: Somatosensory stimulation on the UL affects the sensory, hand function, postural control and ADLs performance.

Purpose: The purposes of this study were to explore changes in pain, mood and the level of posttrauma risk for 2 weeks after acute hand microsurgery and determine predictors of pain 2-week after microsurgery. Method: Using a sample of 84 patients with hand microsurgery, pain, mood, and posttrauma risk were measured by the Brief Pain Inventory-Korea, the modified Profile of mood states, and the Posttrauma risk checklist at 1-day, 1-week and 2-week post-microsurgery. Repeated measures ANOVA and Multiple regression analysis were conducted to evaluate changes in pain, mood, and posttrauma risk over time after the surgery and determine predictors of pain 2-week after the surgery. Results: Pain significantly decreased (F=63.22, p<.001), mood significantly improved (F=41.04, p<.001) 2 weeks after microsurgery and interestingly, posttrauma risk significantly decreased from baseline to 1-week microsurgery but increased at 2-week after microsurgery (F=24.66, p<.001). Approximately 57% of the variance of pain 2-week post-microsurgery was explained by pain at 1-week post-microsurgery, mood and the numbers of injured fingers. Conclusion: The findings suggest the pain control for 1week after acute surgery being critical and posttrauma rehabilitation of injured finger being necessary. Developing nursing interventions is urgently needed to help individuals with impending hand microsurgery.
