Purpose: To report the clinical results of two cases of coronoid process fractures that were treated with volar plating through a medial approach. Materials and Methods: Two fractures of the coronoid process that needed to be fixed were managed with open reduction and internal fixation through a medial approach using 2.4 mm locking compression plates (Compact Hand set$^{(R)}$, Synthes, Switzerland). The patients were followed up for 14 months and 17 months and were evaluated using the Mayo Elbow Performance Score (MEPS). Results: The MEPS was 95 for Case 1 and 100 for Case 2. Active elbow joint motions were $5^{\circ}-120^{\circ}$ (Case 1) and $0^{\circ}-130^{\circ}$ (Case 2). Supination and pronation fully recovered. Conclusion: Satisfactory results can be obtained in cases of coronoid process fractures because volar plating through a medial approach allows sound fixation and early mobilization of the elbow joint.
Chromosome size, number and shape were studied by the centromeric index, the arm ratio and the relative length of chromosome. The chromosomes of 50 early chick embryos which were derived from a pure line of Single Comb White Leghorns were examined. Using a colchicine, hypotonic treatment, fixation and air-drying technique, the clear prometaphase figures were obtained from the whole embryo. The results of the present investigation of chromosome pairs were as follows, 1. Pair 1 and 2; metacentric and submetacentric chromosomes which could be clearly distinguished from each other by size. 2. Pair 3 and 4: acrocentric chromosomes of similar length but the 4th pair had a distinct short arm which was not present in the 3rd. 3, Pair 5; metacentric sex chromosomes, 2 chromosome had relative 5th length but the W chromosome had slightly shorter length than 7th pair of chromosomes. 4. Pair 6; acrocentric chromosomes similar in shape to pair 3 but of little more than half the size. 5, Pair 7 and 8; acrocentric chrocentric but the 7th pairs had a definite short arm. 6. Pair 9; similar length to the 7, 8 pairs but had a medially placed centromere. 7. microchromosomes of 30 pairs ; nearly all acrocentric chromosomes which appeared as paired dots. The total number of diploid was appeared to 72-78. But a number of observations presented the total diploid number in 78 (58%). The inconstancy in number observed in this study was presumably due to the minute size of the microchromosomes. Thus, the modal numbers for the diploid chromosome was at least 78.

This experiment was conducted to clarify the functions of supernodulating characters on seed yield determination through the comparison of agricultural traits of supernodulating soybean mutants, Sakukei4, SS2-2, and their parent cultivars, Enrei and Shinpaldalkong2. The plant dry weights of supernodulating mutants, Sakukei4 and SS2-2, were $52\%$ and $61\%$ of their wild type parents at full seed stage (R6). However, the relative growth rate (RGR) from the pod set stage (R3) to R6 of Sakukei4 was 0.022 g/g/day and that of SS2-2 was 0.016 g/g/day, which were higher than those of their parents. Nodule number and dry weight were increased in two supernodulating mutants by the R6 stage. The nitrogen concentrations of leaf, petiole and stem of Sakukei4 were higher than those of Enrei. SS2-2 showed higher nitrogen concentration in petiole than Shinpaldalkong2 had. The positive correlations were appeared between nodule dry weight, plant dry weight and pod number, in two supernodulating mutants during the period from R3 to R6 stage. Although all of the yield components and seed yield were lower in two supernodulating mutants than their parents at the stage of full maturity (R8), the harvest index was higher in supernodulating mutants. The increasing rates of pod number to stem dry weight in two supernodulating mutants showed the higher than those of two their parents at R8 stage. In conclusion, the relative growth rates during the early to the middle reproductive growth period were higher in supernodulating mutants than the wild types. This could be resulted in an increase in pod number. The increase of relative growth rate was the result of the successive supplement of nitrogen source from biological nitrogen fixation (BNF) of nodules during the middle reproductive growth period in supernodulating mutants.
Five soybean varieties of two early maturing; Karikei 73 and SS79168, and three late maturing; Tohoku 76, Baegunkong and Jangbaegkong, were used and evaluated in the study, Of the varieties examined, Karikei 73 was characterized by the delayed leaf senescence, To investigate the periodical trends of sugars in plant organs and their roles to the nitrogen fixing activity of root nodules, the concentrations of reducing and non-reducing sugar in root and nodules during the grain filling period were measured. The concentration of non-reducing sugar in roots was not changed up to the stage of R6 for all of the varieties but it decreased rapidly thereafter for the varieties except Karikei 73. No such rapid decrease in the concentration of non-reducing sugar in the roots was observed for Karikei 73 having the characteristics of delayed leaf senescence. The concentration of reducing sugar in the root nodules was not greatly changed for all of the varieties up to the stage of R6 regardless of the earliness of varieties but increased temporarily at R6.5 when there was a rapid decrease in ARA. The phenomenon explained the fact that nitrogen fixing activities were controlled not only by supplying sugars as the source of energy for nitrogen fixation, but also by the need for fixed nitrogen of the plant. The concentration of non-reducing sugar in root nodules also increased up to the stage of R6-R6.5 but decreased at R7, which could apply the same explanation as in the concentration of reducing sugar of the root nodules.

Purpose: Arthroscopic repair of rotator cuff tears are many techniques that have been developed to improve the initial postoperative strength of the repair. There was a doubt that current arthroscopic cuff repairs using a single row of suture anchors reproduce insufficient area of the anatomic cuff insertion, and concerns about failure of fixation often lead surgeons to limit early motion. Newer technique of double-row repair in arthroscopic treatment may provide initial stronger fixation and more contact with bone at the repair site than single-row repair did. We studied the comparison between clinical outcomes of arthroscopic single- and double-row repair in cuff tears at 1year postoperatively. Materials and methods: We retrospectively analyzed 40 shoulders with single-row repair and 38 shoulders with double-row repair of full-thickness rotator cuff tears between May 2002 and October 2004. Out of total 78 shoulders, 42 (54%) were male patients and 36 (46%) were female patients and the mean age at surgery was 56 years. All patients were diagnosed by physical examination and MRI. At 1year' follow-up after operation, we evaluated with the ASES and the Constant scoring system, and measured muscle power of abduction, internal and external rotation of the affected shoulder then compared with each other. Results: Mean ASES scores and Constant scores in double-row repair group improved more than single-row repair group significantly at 1year postoperatively. Muscle power of abduction and internal rotation, especially abduction power, improved more significantly in double-row repair group than in single-row repair. Conclusion: Arthroscopic double-row repair for the full thickness rotator cuff tear may be a superior technique, which showed better clinical outcomes and restoration of muscle power compared with single-row repair at relatively short period of postoperative follow-up. Restoration of footprint close to normal anatomy by double-row repair seems to play an important role in the recovery of muscle strength.
Objective : The purpose of this non-randomized prospective study was to evaluate the safety and efficacy of continuous intravenous nalbuphine-ketorolac-droperidol(CIA) versus continuous infusion of epidural morphine-bupivacaine(CEA) for pain control after lumbar spinal surgery. Methods : Twenty-one patients who underwent spine surgery including laminectomy, fusion with fixation were assigned to receive an intravenous bolus of nalbuphine 5mg and ketorolac 15mg, followed by a continuous infusion of nalbuphine 25mg, ketorolac 105mg, and droperidol 5mg mixed with normal saline 98cc(2cc/hr). Twenty patients received a bolus infusion of morphine 2mg and 0.125% bupivacaine 8cc followed by a continuous intravenous infusion of 100cc 0.125% bupivacaine and morphine sulfate 8.0mg(2cc/hr). Pain score was measured on a visual analogue scale(VAS). It's safety and efficacies were compared with the results of continuous infusion of epidural morphine-bupivacaine, which was reported previously by same authors. A continuous infuser was used to give epidural morphine-bupivacaine and intravenous nalbuphine-ketorolac-droperidol. Results : In general, mild pain, pain less than 3 VAS scores, was observed postoperatively from 30minutes to 72hours in CEA group, and from 6 hours to 72 hours in CIA group. The early postoperative pain was controlled easily in 6 hours in CEA group, compared to CIA group(p<0.05). However, there was no statistical significance in 72 hours on pain scores between CEA and CIA groups after 6-12hours of pain managements. Pruritus, nausea and vomiting, and urinary retention were more frequent in CEA group. Conclusion : CIA and CEA are considered effective methods in postoperative pain managements. However, adequate doses in early intravenous infusion and continuous intravenous analgesia with nalbuphine-ketorolac-droperidol will be needed for better control in early postoperative pain with less side effects.

The low and unstable yield of soybean has been a major problem in Japan. Excess soil moisture conditions are one of the major factors to restrict soybean productivity. More than 80 % of soybean crops are cultivated in converted paddy fields which often have poor drainage. In central and eastern regions of Japan, the early vegetative growth of soybean tends to be restricted by the flooding damage because the early growth period is overlapped with the rainy season. Field observation shows that induced excess water stress in early vegetative stage reduces dry matter production by decreasing intercepted radiation by leaf and radiation use efficiency (RUE) (Bajgain et al., 2015). Therefore, it is necessary to evaluate the responses of soybean growth for excess water conditions to assess these effects on soybean productions. In this study, we aim to modify the soybean crop model (Sinclair et al., 2003) by adding the components of the restriction of leaf area development and RUE for adaptable to excess water conditions. This model was consist of five components, phenological model, leaf area development model, dry matter production model, plant nitrogen model and soil water balance model. The model structures and parameters were estimated from the data obtained from the field experiment in Tsukuba. The excess water effects on the leaf area development were modeled with consideration of decrease of blanch emergence and individual leaf expansion as a function of temperature and ground water level from pot experiments. The nitrogen fixation and nitrogen absorption from soil were assumed to be inhibited by excess water stress and the RUE was assumed to be decreasing according to the decline of leaf nitrogen concentration. The results of the modified model were better agreement with the field observations of the induced excess water stress in paddy field. By coupling the crop model and the ground water level model, it may be possible to assess the impact of excess water conditions for soybean production quantitatively.
Fracture about proximal humerus may be classified as the articular segment or the anatomical neck, the greater tuberosity, the lesser tuberosity, and the shaft or surgical neck. Now, usually used, Neer's classification is based on the number of segments displaced, over 1cm of displaced or more than 45 degrees of angulation , rather than the number of fracture line . Absolute indication of a operative treatment a open fracture, the fracture with vascular injury or nerve injury , and unreductable fracture-dislocation . Inversely, the case that are severe osteoporosis, and eldly patient who can't be operated by strong internal fixation is better than arthroplasty used by primary prosthetic replacement and early rehabilitation program than open reduction and internal fixation. The operator make a decision for the patient who should be taken the open reduction and internal fixation, because it's different that anatomical morphology, bone density, condition of patient. The operator decide operation procedure. For example, percutaneous pinning, open reduction, plate & screws, wire tension bands combined with some intramedullary device are operation procedure that operator can decide . The poor health condition for other health problem, fracture with unstable vital sign and severe osteoporosis , are the relative contraindication. The stable fracture without dislocation is not the operative indication . The radiologic film of the prokimal humerus before the operation can not predict for fracture evaluation. It's necessary to good radiologic film for evaluation of fracture form. The trauma serise is better than the other radiologic film for evaluation. The accessary radiologic exam is able to help for evaluation of bone fragment and anatomy. The CT can be helpful in evaluating these injury, especially if the extract fracture type cannot be determined from plain roenterogram of the proximal humerus, bone of humerus head. If the dislocation is severe anatomically , we could consider to do three dimentional remodelling. The MRI doing for observing of bony morphology before the operation is not better than CT If we were suspicious of vascular injury, we could consider the angiography.
One form of the anomalies of stock price changes as reaction to earnings information is believed to be caused by the so-called earnings fixation, which is the overreaction of stock prices to earnings. According to the Sloan (1996) study, stock price changes are positively associated with earnings at the time of earnings releases, but the association becomes negative after that, as the early overreaction is corrected. However, the problem in his study is to use cash flows computed by adjusting earnings with appropriate income statement and balance sheet items. As Bahnson et al. (1996) show, these cash flows substantially deviate from SFAS No. 95 cash flows and the sample used in this study is found to be subject to this substantial measurement error. Therefore, the result of Sloan might be driven by this error and the reexamination of earnings fixation is warranted. The results are generally consistent with those in Sloan. First, earnings is positively associated with stock price changes at the time of earnings releases, but the association becomes negative after that. Second, cash flows show a weak association with stock price changes at the time of earnings releases, but the association become stronger thereafter. Third, when seperated from cash flows, accruals have an incremental explanation about stock price changes beyond that of cash flows, accruals have a negative association later on. This finding is consistent with stock price overreaction to accruals, even when more cleaner cash flow data are used.
In 1814, Giovanni Battista Monteggia first described two cases of fracture of proximal third of ulna with a dislocation of radial head, and this combined injury is now known as the Monteggia fracture. Despite its rarity, the importance of early recognition of dislocated radial head and correct treatment bas been emphasized. Eight cases of Monteggia fracture were studied from March, 1984 to June, 1987. The results are as follows 1. Male patients were six and female were two. 2. The frequent cause of injury was fall down in four cases. 3. Bado type I accounted for 50%, type II for 12.5% and type III for 37.5%. 4. The level of ulna fracture was above upper one third of ulna in seven. 5. The common direction of dislocated radial head was anterior. 6. Two children and two adults were managed by closed reduction. Four ulna fractures in adult were treated by open reduction and internal fixation using a semitubular plate. 7. The results (by Bruce et al. criteria) were 3 excellent, 2 good, 1 fair and 2 poor.
