Objectives : The purpose of this study is to study the effects of acupuncture on Young-gol and Dae-back on night fever and investigate the meridian and collateral aspects of Dong-Si acupuncture through cases of night fever due to Yin deficiency. Methods : Patients have received acupuncture on both sides(Young-gol and Dae-back) at 10 pm. The acupuncture treatment lasted for 15 minutes. Body temperature, pulse, and Numeric Rating Scale(NRS) scores for dryness of mouth were measured for the evaluation. Results : Both patients reported symptomatic reduction including night fever, pulse rate, NRS about dry mouth following the described treatments. The night fever disappeared after acupuncture treatment. The mean of pulse rate changed from 82.6 to 74.8(case 1), from 83.5 to 74.3(case 2). The mean of NRS changed from 4.2 to 1.7(case 1), from 3.3 to 2.4(case 2). Conclusions : In both cases, acupuncture was effective in relieving night fever symptoms. This can be considered from meridian and collateral aspects and the Korean medicine physiological perspective. In the future, systematic and diverse studies related to this will be needed.

This study presents the analysis of flow and bed change characteristics considering bed protection work built on the immediate downstream of weir to protect river bed from scouring. The study area is 37km reach from Hyunpoong station to Masuwon station including Hapcheon- Changryoung multi-function weir in the Nakdong river. CCHE2D model is calibrated and validated for evaluating the flow and bed change characteristics during Typhoon Kompasu in 2010. Three simulation conditions are set up: Case 1 is a natural channel without installation of weir. Case 2 involves an installation of weir in the natural channel. Case 3 involves an installation of weir with bed protection in the natural channel. Flood frequency (50, 100 and 200yr) is applied to each scenario to analyze the effects of bed protection work. While the sediment rate is increased in the downstream of fixed gate and sluice-type gate, river bed scouring rate is increased in the downstream of lift-type gate in Case 2 comparing with the results of Case 1. The river bed scouring is not occurred in the immediate downstream of weir (~30m) due to the effect of bed protection, but larger amount of sediment is occurred in the downstream of weir (60m~) which the bed protection is not installed comparing with the results Case 1. Through the results of simulation considering bed protection work, this study would be helpful to expect bed change and operate the weir as well as manage.

Recently, Wu proposed a three small classes of finite fields $F_{2^n}$ for low-complexity bit-parallel multipliers. The proposed multipliers have low-complexities compared with those based on the irreducible pentanomials. In this paper, we propose a new Repeated Polynomial(RP) for low-complexity bit-parallel multipliers over $F_{2^n}$. Also, three classes of Irreducible Repeated polynomials are considered which are denoted, respectively, by case 1, case 2 and case3. The proposed RP bit-parallel multiplier has lower complexities than ones based on pentanomials. If we consider finite fields that have neither a ESP nor a trinomial as an irreducible polynomial when $n\leq1,000$. Then, in Wu''s result, only 11 finite fields exist for three types of irreducible polynomials when $n\leq1,000$. However, in our result, there are 181, 232, and 443 finite fields of case 1, 2 and 3, respectively.

Dilated cardiomyopathy in two dogs showing dyspnea was diagnosed at veterinary teaching hospital. In radiographs, cardiomegaly, pleural effusion, pulmonary edema, ascites, and hepatomegaly were seen at case 1. ‘Reversed D’ shape due to right heart enlargement was shown at case 2. In echocardiography, dilatation of chambers was predominant in case 1 and 2. Arrythmia was complicated in case 2.

Nitrogen oxides (NOx) have recently been very influential in the generation of ultrafine dust, which is of great social interest in terms of improving the atmospheric environment. Nitrogen oxides are generated mainly by the reaction of nitrogen and oxygen in air in a combustion gas atmosphere of high temperature in a combustion apparatus such as thermal power generation. Recently, research has been conducted on the combustion that recirculates the exhaust gas to the cylindrical burner by using a piping using a Coanda nozzle. In this study, three types of burners were carried out through computational fluid analysis. Case 1 burner with the outlet of the combustion gas to the right, Case 2 burner with both sides as gas exit, Case 3 burner with left side gas exit. The pressure, flow, temperature, combustion reaction rate and distribution characteristics of nitrogen oxides were compared and analyzed. The combustion reaction occurred in Case 1 and Case 2 burner in the right direction with combustion gas recirculation inlet and Case 3 burner in the vicinity of mixed gas inlet. The temperature at the outlet was about $100^{\circ}C$ lower than that of the other burners as the Case 2 burner was exhausted to both sides. The NOx concentration of Case 1 burner at the exit was about 20 times larger than that of the other burners. From the present study, it could be seen that it is effective for the NOx reduction to exhaust the exhaust gas to both side gas exits or to exhaust the exhaust gas to the opposite direction of inlet of recirculation gas.

The period from .1959 to 1976, authors experienced 13 cases of thymoma at the Department of Thoracic and Cardiovascular Surgery in National Medical Center. Ten patients were male, and 3 patients were female.Main complaints were cough 76.9%, dyspnea, 69.2%, chest pain 61.6%, myasthenia gravis 23.1 % and S.V.S 23.1%. All of them located anterior mediastinum. 7 cases were benign and 6 cases were malignant. Lymphocytic type was 5 cases, epithelial type 3 case,spindle cell type 1 case, mixed type 2 cases, cystic type 1 case and seminomatous type 1 case. All cases were surgically approached but in malignant cases, only 1 case was palliatively removed and followed radiation therapy. 4 cases were made only biopsy, among them, obstained good response with radiation therapy in seminomatous type case. In benign cases, excellent result was obtained but 2 cases which were combined myasthenia gravis were relapsed the symptoms.

We have experienced 6 cases of esophageal perforation from September, 1988 to June, 1993, in the department of Thoracic and Cardiovascular Surgery, Chungang Univesity Hospital and obtained the following results. The number of male patients was 5, and female 1.The causes of esophageal perforations were spontaneous, post-emetic in 2 cases, spur of cervical spine in 1 case, foreign body in 1 case, surgical trauma in 1 case and blunt trauma in 1 case. Perforation developed in cervical esophagus in I case,and others in distal third of the esophagus. One case needed only conservative treatment, and others needed surgical intervention minor or major. There were 2 mortality cases, and 2 cases healed satisfactorily without complication, 2 cases had complications that needed reoperations.

As the first step toward real-time multi-core computing, this paper presents a novel approach to bounding the worst-case performance for threads running on multi-core processors with shared L2 instruction caches. The idea of our approach is to compute the worst-case instruction access interferences between different threads based on the program control flow information of each thread, which can be statically analyzed. Our experiments indicate that the proposed approach can reasonably estimate the worst-case shared L2 instruction cache misses by considering the inter-thread instruction conflicts. Also, the worst-case execution time (WCET) of applications running on multi-core processors estimated by our approach is much better than the estimation by simply assuming all L2 instruction accesses are misses.

Objectives This study aimed to provide a basis for treatment of soyang person by investigate published case series of soyangin Methods We have reviewed case series of soyangin in the Journal of Sasang Medicine from 2007 to 2016. Results A total of 16 case series related to soyangin were reported. Among them, herbal medicine was used in 16 papers (100.0%), of which 'Hyeongbangjihwang-tang' was the most frequently used, reported in five papers (31.3%). For acupuncture of 12 papers (75.0%), acupoint 'ST36' was the most frequently used, reported in four papers (33.3%). Conclusions Most of the included case series were effective in treating patients of soyangin. However, the number of papers was insufficient to suggest standardized treatment for "diseases-Sasang medicine pattern-treatment" systems.

We have investigated correlation between airtightness measured by blower door and airborne sound insulation measured in the upper and lower units. We consist of two cases : all windows sealed(CASE 1) and not sealed(CASE 2). As a result, CASE 1 is tighter than CASE 2 in airtightness, but CASE 1 is lower than CASE 2 in sound level difference. This is because of big wind on measuring CASE 1. Thus we are going to measure them at another fields considering this factor. Finally we ought to find out the correlation between airtightness and sound insulation.
