Objective : Chu Cheng(褚澄) was known as the author of Zayaofang(雜藥方) and Chushiyishu(褚氏遺書). His mentions in the medicine have been sufficiently told in his posterity. However, there have been no studies on Chu Cheng and his work like Chushiyishu in Korea. Here, I seek to investigate Chu Cheng and his ideas in the medicine. Method : I investigate Chushiyishu, known as written by Chu Cheng and his scattered portions. Result & Conclusion : His nom de plume(字) is Yandao(彦道). It was supposed that he was born before the year of 420, the era of Dong Jin(東晉) and died in 483. He wrote Zayaofang and Chushiyishu. However, the former was lost. The latter consists of 10 pieces of medical theories. The contents carved on the stone plate was discovered for the first time before 934 at a place presumed as his grave. Then, it was stored as the inner and outer coffins in the tomb of Xiao Guang(蕭廣) in 935 and written on the paper by Buddhist monk Shi Yikan(釋義堪) in 1127. Then, Liu Jixian(劉繼先) carved on the wood for publication and finally, the work was released in 1201. But, it deeply looks that the book was written by other follower. Chu Cheng was a doctor excellent in the inspection and pulse method and his medical ideas prioritized Huo(火) in Mingmen(命門) and Spleen(脾). He expressed his opinions on the four phases of life, sexes and birth defects through Yangjing(陽精) and Yinxue(陰血). In addition, he explained the human pathology through Qixue(氣血). Unsmooth flow of Qi causes diseases by congestion. The entity circulating Yinxue is Yang and protested using urine to treat the hemoptysis(咳血) instead of medicine with cold features. It was frequently mentioned by his predecessors with the fact that Chu Cheng used different medications on housewives from widows and Buddhist nun monks. In addition, Chu Cheng proposed various opinions on cure, diagnosis, treatment, drug usage, pulse positions and hermaphrodites(半陰陽).

Purpose : The aim of this study was to identify the relation of cognition and visuospatial perception in stoke patients. Methods : A total of 16 stroke patients recruited from two hospital located in Donghae, Kang-won participated in this study(Right hemiplegia : twelve, Left hemiplegia : four). All participants scored higher than 20 point on the MMSE-K. To assess the cognitive function, we performed the Korean version of Mini Mental State Examination(MMSE-K), spatial perception domain of Lowenstein Occupational Therapy Cognition Assessment(LOTCA), Figure Color Copy(FCC), Linebisection Test(LBT) and Albert's test in stoke patients. Results: The Korean version of Mini Mental State Examination and spatial perception domain of Lowenstein Occupational Therapy Cognition Assessment were the highest points in sixty ages, Figure Color Copy is difference between Right hemiplegia and Left hemiplegia. Linebisection Test(LBT) and Albert's test had much relation, visuospatial perception had not relationship. Conclusion: Aging was cognition function and visuospatial perception had an interrelationship. visuospatial perception according to affected side in brain had an interrelationship but cognition function and visuospatial perception had not any interrelationship.

Background: Esophageal cancer is one of the major health concerns in Southeast Asian countries, including Thailand. However, only a limited number of studies have been reported from this region. This study was designed to evaluate the prevalence, clinical characteristics and survival rate of esophageal cancer in Thailand. Materials and Methods: Clinical information, histological features and endoscopic findings were collected from a tertiary care center in central region of Thailand between September 2011- November 2014 and reviewed. Results: A total of 64 esophageal cancer patients including 58 men and 6 women with mean age of 62.6 years were enrolled. Common presenting symptoms were dysphagia (74%), dyspepsia (10%) and hematemesis (8%). Mean duration of symptoms prior to diagnosis was 72 days. Esophageal stenosis with contact bleeding was the most common endoscopic finding (55.6%). The location of cancer was found in proximal (16%), middle (50%) and distal (34%) esophagus. Squamous cell carcinoma was far more common histology than adenocarcinoma (84.2% vs 10.5%). However, esophageal adenocarcinoma was significantly more common than squamous cell carcinoma in distal area of esophagus (100% vs 22.9%; p=0.0001, OR=1.6, 95%CI=1.1-2.2). Esophageal cancer stages 3 and 4 accounted for 35.2% and 59.3% respectively. Overall 2-year survival rate was 20% and only 16% in metastatic patients. Conclusions: Most esophageal cancer patients in Thailand have squamous cell carcinoma and nearly all present at advanced stage with a grave prognosis. Screening of high risk individuals and early detection might be important keys to improve the survival rate and treatment outcome in Thailand.

This paper deals with the performance analysis of LIPCA(Light-weight Piezo-Composite actuator) including the material nun-linearity of the embedded 3203HD PZT wafer. For this analysis, we used a piezo-shell element code based on a nine-node assumed strain shell element formulation. The material non-linearity was implemented in the formulation due to a large observed discrepancy between the measured displacement and the computed actuation displacement based on the linear analysis. An experimentally extracted piezo-strain function of the PZT wafer and incremental formulation were incorporated into the linear finite element code to improve the accuracy of the estimated actuation displacement of the LIPCA. The non-linear piezo-shell program was used to predict the non-linear performance of the LIPCA. The simulated actuation displacement from the non-linear code showed much better agreement with the measured data.

The present study was aimed at investigating the metabolic regulation of insulin-like growth factor-I(IGF-I) expression in fasting animals. The expression of IGF-I gene was determined by a solution hybridization/RNase protection assay using total RNA from control, 4d-fasting, and 2d-fasting-refed rats. The levels of IGF-I transcripts were reduced in 4d-fasting than in control by decreasing its transcriptional rate, which was measured through nuclear nun-on assay. DNase I footprinting, which was performed using nuclear extracts from fasting rat, demonstrated protein binding to a sequence that extended from +179 to +210 (termed region B). These data suggest that the expression of IGF-I is transcriptionally regulated through DNA-liver enriched protein binding in a sequence which is located downstream from major transcription initiation site of IGF-I gene.

In vitro propagation of Neoregeria carorinae 'Tricolor' was achieved by using immature flowers and lateral buds, and the plantlets from tissue culture were transplanted and cultivated in greenhouse. The picking times of explants to decrease disappearance of stripes, and in vivo the growth and flowering of regenerated plantlets as influenced by in vivo healed nun were investigated. The normal plantlet were obtained at a frequency of 67%, in the culture of immature flowers picked at 4 weeks after flower bud differentiation, while all leaf stripes disappeared in the culture of immature flowers picked 1 and 5 weeks after flower bud differentiation. In vivo growth of plantlet from immature flower buds was better than those from lateral buds, and the flowering of 27.8% showed in the greenhouse culture of plantlet from immature culture, but the plantlets from lateral buds did not flower at all. The plantlets rooted on the medium with 0.5 mg/L IBA were the most favorable in green house culture, and the kinds and concentrations of auxin in vitro did not have any influence on variation of plane cultured in greenhouse.

In this paper, we propose a real tine moving object tracking system based on block-based image processing technique and human visual processing. The system has two nun features. First, to take advantage of the merit of the biological mechanism of human retina, the system has two cameras, a CCD(Charge-Coupled Device) camera equipped with wide angle lens for more wide scope vision and a Pan-Tilt-Zoon tamers. Second, the system divides the input image into a numbers of blocks and processes coarsely to reduce the rate of tracking error and the processing time. Tn an experiment, the system showed satisfactory performances coping with almost every noisy image, detecting moving objects very int and controlling the Pan-Tilt-Zoom camera precisely.

Printed wiring boards(PWBs) of the obsolete computers are composed of various organic and inorganic compounds as well as metals and alloys. As convinced that the valuable metals obtained from the PWBs are effectively utilized as secondary resources when recovered by economical methods, in this study, an investigation for characterizing the physical separation techniques is conducted. For the recovery of them, the sockets and chips dismantled from PWBs by scraping and residual resin boards are subjected to the appropriate separation processes according to the physical properties of each part. In the case of crushed socket scraps size ranged from -2.36 mm to +1.18 mm, approximately 97 wt% of the product obtained by magnetic separation consists of metallic compounds. In the case of chip scraps, 97% of Fe-Ni alloy and 95% of Cu metal are recovered by the combined process of air classification and dry magnetic separation in the size range from -2.36 mm to +0.15 mm. Ball milling is adopted in order to improve the removal efficiency of the thin-printed metallic materials on the residual resin boards and approximately 77% of Cu metal is recovered by zigzag separation after ball milling.

Quality of fresh-cut tomato slices was compared during cold storage under various modified atmosphere packaging conditions. Chilling injury of slices in containers sealed with Film A was higher than with Film B; these films had oxygen transmission rates of 87.4 and 60.0 ml h-1 m-2 nun-1 at $5^{\circ}C$ and $99\%$ RH, respectively. While slices in containers with an initial atmospheric composition of air, $4\%$ CO2 + 1 or $20\%\;O_2, \;8\%\;CO_2+1$ or $20\%\;O_2$, or $12\%\; CO_2+\;20\%\;O_2$ showed fungal growth, slices in containers with $12\%\;CO_2 +\;1\%\;O_2$ did not. Low ethylene in containers enhanced chilling injury. Modified atmosphere packaging provided good quality tomato slices with a shelf-life of 2 weeks or more at $5^{\circ}C$. Experiments were conducted to compare changes in quality of slices of red tomato (Lycopersicon esculentum Mill. 'Sunbeam') fruit from plants grown using black polyethylene or hairy vetch mulches under various foliar disease management systems including: no fungicide applications (NF), a disease forecasting model (Tom-Cast), and weekly fungicide applications (WF), during storage at $5^{\circ}C$ under a modified atmosphere. Slices were analyzed for firmness, soluble solids content (SCC), titratable acidity (TA), pH, electrolyte leakage, fungi, yeasts, and chilling injury. With both NF and Tom-Cast fungicide treatments, slices from tomato fruit grown with hairy vetch (Vicia villosa Roth) mulch were firmer than those from tomato fruit grown with black polyethylene mulch after 12 days storage. Ethylene Production of slices from fruit grown using hairy vetch mulch under Tom-Cast was about 1.5- and 5-fold higher than that of slices from WF and NF fungicide treatments after 12 days, respectively. The percentage of water-soaked areas (chilling injury) for slices from tomato fruit grown.

In den kommunikativen orientierten Sprechbehandlungen lassen sich negative $S\"{a}tze$ allgemein als Klasse kommunikativer Operlationen mit spezifischen kommunikativ-pragmatischen Funktionen kennzeichnen. Diese Funktionen, die der Sprecher mit den sogenannten negativen $Behauptungss\"{a}tzen$ in wirklichen kommunikativen Sprechakten $ausdr\"{u}ckt$, stellen dabei Handlungs-bzw. Sprechhandlungsintentionen des Sprechers dar. Sie $k\"{o}nnen$ aus den in negierten $\"{A}u{\ss}erungen$ implizierten Sprecher-Einstellungen zu bestimmten Sachverhalten, die in den vorangehenden $\"{A}u{\ss}erungen\;seines\;Gespr\"{a}chpartners\;ausgedr\"{u}ckt$ werden, abgeleitet werden. In diesem Zusammenhang sind die negativen $Behauptungss\"{a}tze$ erst dann sinnvoll darzustellen, wenn sie mit Voraussetzungsstruktur verbunnden werden. D.h. also die Funktionen der negativen $Behauptungss\"{a}tze\;k\"{o}nnen$ im Zusammenhang mit einer(bzw. mehreren) vorangehenden $\"{A}u{\ss}erung(en)\;des\;Gepr\"{a}chpartners$ oder den aktuellen $Sprechhandlungsumst\"{a}nden\;besser\;erkl\"{a}rt$ werden. Aus solchen kommunikativen Situationen kann man bestimmte Einstellungen des $Gespr\"{a}chspartners$ annehmen. So haben wir negative $Behauptungss\"{a}tze$, die mit den in Grammatiken angenommenen verschiedenen $Negationsw\"{o}rtern$ verwirklicht werden, in die Subkategorie der Sprechhandlungen eingesetzt, um ihre sinnvollen Funktionen zu bezeichnen. Dabei stellen wir fest $da\ss$ den negativen $Behauptungss\"{a}tzen$ nicht nur eine Sprechhandlung 'Verneinen' zuzuordnen ist. In den aktuellen Sprechhandlungen zeigen sie auch die anderen kommunikativ-pragmatisch orientierten Funktionen. Wir klassifizieren nun die folgenden illokutionaren Typen: 1) Verneinen(bzw. Negieren); 2) Widersprechen; 3) $Pr\"{a}zisieren$ (oder Korrigier); 4) Behaupten; 5) Antworten auf Wortfrage; 6) Zustimmen; 7) Verweigern
