The purpose of this study was to examine physiological changes of the body according to various weight loads and the holding during carrying object. The experiments were conducted with utilizing physiological analyses for five male and five female adults as subjects. The results were as followed. 1. Any significant difference was not shown in heart rate, ventilation and amount of oxygen uptake of male subjects in the case of no load and 5kg. And also no significant difference was shown in expiratory exchange ratio of male subjects of no load, 5kg and 10kg, but in other measure items and other stages of weight was shown. 2. Significant differences were shown in heart rate, ventilation, defluxion of carbon dioxide, oxygen uptake per body weights, respiratory exchange rate, respiration rate and all other measure items of female subjects in all stages of load. 3. In the MMH job, there was no influence on male subjects up to 5kg loads, but there was an significant difference in male subjects in load walking from 5kg. It shows that even in 5kg weight MMH work, female subject's expiratory function was influenced. 4. 10kg load was the limit weight of female subjects and 15kg was of male subjects when they walked on treadmills with 4km/h velocity for 3 minutes, holding loads in the right and vertical types.

This paper considers the problem of detecting elliptical curves using Advanced Hough transform. Storage and efficiency problems are over come by decomposing the problem into two stages. The first stage uses a novel constraint as the basis for a Randomined Hough transform to detect the ellipse centre while the second stage finds the remaning parameters using simple but efficient focusing implementation of the Advaned Hough transform. The method is applicable in many situations where previous Hough transform schemes would fail. Results are demonstrated for comolicated image data containing several occluding ellipses.

저자들은 척수압박으로 하지마비를 보인 환자에서 수술 후에 급성 백혈병에 동반된 과립구성 육종으로 진단된 환자 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Granulocytic sarcoma(GS) is an uncommon tumor composed of immature cells of the granulocytic series. Most case of GS occur in the course of acute leukemia and the blast crisis of chronic leukemia, Rarely, however, it may present before leukemia becomes clinically apparent. It may also occur in patients with myeloproliferative disoders. GS has been reported that it occurs in 3% to 9% of patients with acute myelogenous leukemia(AML) and the incidence of GS is reported to be higher in patients with t(8;21). GS occurs relatively commonly in africa and has been reported to affect 10-25% of black children presenting with AML. This is very rare case of granulocytic sarcoma with AML(FAB M5) presented with spinal cord compression which was supported by decompression laminectomy.

A case of Lupus vulgaris associated with scrofuloderma in a 11 year old girl is reported. The girl presented painless swellings, the left being more severe, on her both cheeks. A red, elevated, about 3 x 5 cm in size, partly eroded plaques is seen on her left cheek. On diascopy couple of so called apple jelly nodes are found within the plaque. A long linear red, scar like lesion is also found on her dlavicular area. Submandiblar lymph nodes are enlarged and hard. On right submandibular region there were two finger tip sized dome shaped red swellings which are connected with hard enlarged lymph nodes by cord like strings. The biopsy from left cheek disclosed typical picture of lupus vulgaris. The patient was refered to surgical clinic and was never seen again.

Epidermolytic Hyperkeratosis is a rare variant of ichthyosis, transmitted as autosomal dominant inheritance. A 2-year-old male baby, in whom no hereditary back ground was found, showed typical clinical and histopathological features of Epiderrnolytic Hyperkeratosis. The possibility of occuring the disease without hereditary back grcund, clinical features, and histological characteristics of the disease are discussed.

<P>Intracellular reactive oxygen species (ROS) are essential secondary messengers in many signaling cascades governing innate immunity and cellular functions. TLR3 signaling is crucially involved in antiviral innate and inflammatory responses; however, the roles of ROS in TLR3 signaling remain largely unknown. In this study, we show that TLR3-induced ROS generation is required for the activation of NF-κB, IFN-regulatory factor 3, and STAT1-mediated innate immune responses in macrophages. TLR3 induction led to a rapid increase in ROS generation and a physical association between components of the NADPH oxidase (NOX) enzyme complex (NOX2 and p47<I><SUP>phox</SUP></I>) and TLR3 via a Ca<SUP>2+</SUP>-c-Src tyrosine kinase–dependent pathway. TLR3-induced ROS generation, NOX2, and p47<I><SUP>phox</SUP></I> were required for the phosphorylation and nuclear translocation of STAT1 and STAT2. TLR3-induced activation of STAT1 contributed to the generation of inflammatory mediators, which was significantly attenuated in NOX2- and p47<I><SUP>phox</SUP></I>-deficient macrophages, suggesting a role for ROS-STAT1 in TLR3-mediated innate immune responses. Collectively, these results provide a novel insight into the crucial role that TLR3-ROS signaling plays in innate immune responses by activating STAT1.</P>
Effects of Fan-Aspirated Radiation Shield for Temperature Measurement in Greenhouse Environment
Yang, Seung-Hwan,Lee, Chun-Gu,Kim, Joon-Yong,Lee, Won-Kyu,Ashtinai-Araghi, A.,Rhee, Joong-Yong Korean Society for Agricultural Machinery 2012 바이오시스템공학 Vol.37 No.4
Purpose: Provision of accurate temperature measurement is an essential element to ensure a precise control in greenhouse environment. This study was organized to compare the effects of six solar radiation shields with different shapes for temperature measurement and find the most appropriate shield for greenhouse environment. Methods: A fan-aspirated radiation shield was designed and manufactured. Using the fan-aspirated radiation shield and five other shapes i.e., the cup shape, horizontal pipe, vertical pipe, parallel boards and commercial shields, temperature measurement was conducted over the lawn surface as well as greenhouse indoor environment. The measurement height varied at 0.5, 1.0 and 1.5 m from the floor. Results: The measured temperatures by the fan-aspirated radiation shield were 1.30-$1.49^{\circ}C$ lower than the values recorded by other different-shaped shields at 1.5 m of measurement height. As the measurement height decreases, observed differences between measured temperatures of the fan-aspirated radiation shield and other shields demonstrate a declining trend. However, at low measurement heights, the radiation emitted from the bottom surface would be the source of error in temperature measurement. Conclusions: The fan-aspirated radiation shield is a required tool for exact measurement of air temperature in greenhouse temperature control.

A decrease in pass ratio of Korean exporting pears causes several negative effects including an increase in pesticide dependency. In this study, we attempted to establish the pest forecasting management system, composed of weekly field forecasting by pear farmers, meteorological data obtained by automatic weather station (AWS), newly designed internet web page (http://pearpest.jnu.ac.kr/) as information collecting and providing ground, and information providing service. The weekly field forecasting information on major pear diseases and pests was collected from the forecasting team composed of five team leaders from each pear exporting complex. Further, an abridged weather information for the prediction of an infestation of major disease (pear scab) and pest (pear psylla and scale species) was obtained from an AWS installed at Bonghwang in Naju City. Such information was then promptly uploaded on the web page and also publicized to the pear famers specializing in export. We hope this pest forecasting management system increases the pass ratio of Korean exporting pears throughout establishment of famer-oriented forecasting, inspiring famers` effort for the prevention and forecasting of diseases and pests occurring at pear orchards.
