This study was designed to produce rounded belt pattern and tight-skirt pattern drafting method using 3D body scan data. Subjects were thirty women in their early twenties. In order to figure out the optimum cutting points, namely, where darts are made, using CAD program, curve ratio inflection points on the horizontal curve of waist, abdomen, and hip to find 1 point in the front, two points in the back part. The average length from center front point to maximum curve ratio was 7.7 cm(46.3%) on the waist curve; 7.9 cm(39.4%) on the abdomen curve. And the average length from center back point to maximum curve ratio point was 6.9 cm(39.0%) for first dart and 11.2 cm(63.3%) for second dart on the waist curve; 8.9 cm(35.8%) for first dart and 15.7 cm(63.3%) for second dart on the hip curve respectively. The cutting lines from were made up by connecting curve inflection points. After divided using cutting lines, each patch was flattened onto the plane and all the technical design factors related with patternmaking were measured, such as dart amount, lifting amount of side waist point, etc. Based on the results of correlation analysis among these factors, regression analysis was done to produce equations to estimate the variables necessary to draw up pattern draft method; F1=F8+1.1, $F4=2.5{\times}F2+0.9$, $F5=0.9{\times}F4+1.0$, $F6=0.3{\times}F4+0.4$, $B1=0.9{\times}B8+2.3$, $B4=2.1{\times}B2+1.3$, $B5=0.9{\times}B4+3.5$, and $B6=0.3{\times}B4+0.4$.

Agricultural workers who mix/loads and spray pesticide in fields expose to pesticide through dermal and inhalation routes. In such situation, exposed amount should be measured quantitatively for reasonable risk assessment. Patch, gloves, socks and mask will be good materials for monitoring for dermal exposure while personal air monitor equipped with solid adsorbent and air pump will be a tool for inhalation exposure. For extrapolation of absorbed amount in dermal exposure matrices and of trapped amount in solid sorbent to total deraml or inhalation exposure, Korean standard body surface area and respiration rate were proposed in substitution of EPA data. Important exposure factors such as clothing and skin penetration ratio of dermal and inhalation exposure were suggested based on Spraying time for exposure monitoring must be long enough that the amount of pesticide to get absorbed/trapped in exposure matrices results in reasonable analytical value. In domestic case for the both of speed sprayer and power spray machine, spraying time of 20~40 minutes (0.1~0.2 ha) will be reasonable per single replicate before extrapolating to 4 hours a day with triplicates experiment.

The genus Paracalanus Boeck, 1864 dominate zooplankton communities in waters off Korean peninsula. Zooplankton samples collected from four waters (Uljin, Hadong, Youngkwang, Cheju) were sorted for specimens belonging to the genus Paracalanus. Paracalanus sp. regarded to p. paMus or p. indicus were examined. Body of male has cephalosome dorsal hump (CDH). Urosomites have four segments in female and five segments in male. In male, antennule is symmetry and fused without geniculation. The male antennule carries more aesthetascs than those in female antennule. Female P1-P4 is similar to those of male in seta and spine formular. Spinules on surface of legs are different each other. The female P5 is symmetrical, and composed of 2 segment. In male, it is aymmetrical and left leg composed of 5 segments, right leg 2-segmented. Male found patch of fine spinule on terminal inner surface of outer process on fifth segment. Sexual dimorphism appear saliently in mouth appendages. Mandible lacks of gnathobase; maxillule is apparently reduced; maxilla degrades it i]l female and remains vestiges between maxillule and maxilliped; maxilliped terminal part indistinctly articulated and carrying behind three strong plumose setae. With the absence of gnathobase in male, we conclude that male Paracalanus sp. does not feed.

Korea mountain ginseng known as oriental miracle drug is an important medicinal plant. The effect of mountain ginseng adventitious roots extract has been described. The valuable root of mountain ginseng contained several kinds of ginsenosides that have been confirmed to have many active functions for the human body. However, the study of mountain ginseng has a limit because the price of wild ginseng is very expensive and rare. The mountain ginseng adventitious roots were derived from mountain ginseng callus that were induced from mountain ginseng roots. Adventitious roots were separated from callus and grown in solid media(Murachige and stoog media). It was cultured in a 20L bioreactor. After culturing for 40days, adventitious roots were harvested. Afterwards the harvested mountain ginseng adventitious roots were dryed and extracted. We examined the effect on melanogenesis of mountain ginseng adventitious roots extrac. Here, we report the inhibitory effect of melanin biosynthesis on the adventitious roots extract of In vitro test. Also, we assessed the safety of adventitious roots extract. In vitro, cytotoxicity of adventitious roots extract was assessed in mouse fibroblast using two method: The neutral red uptake assay and the MTT assay. In vivo, the allergic and irritant were patch tested in 30 patients. Consequently, extract of mountain ginseng adventitious roots have inhibitory effect on melanin biosynnthesis in B-16 melanoma cell test, tyrosinase inhibitory test and DOPA auto-oxidation test. There were decreased 86%(0.5% concentration), 45%(1% concentration) and 61%(1% concentration), respectively

Person re-identification is to match pedestrians observed from non-overlapping camera views. It has important applications in video surveillance such as person retrieval, person tracking, and activity analysis. However, it is a very challenging problem due to illumination, pose and viewpoint variations between non-overlapping camera views. In this work, we propose a viewpoint invariant method for matching pedestrian images using orientation of pedestrian. First, the proposed method divides a pedestrian image into patches and assigns angle to a patch using the orientation of the pedestrian under the assumption that a person body has the cylindrical shape. The difference between angles are then used to compute the similarity between patches. We applied the proposed method to real-time global multi-object tracking across multiple disjoint cameras with non-overlapping field of views. Re-identification algorithm makes global trajectories by connecting local trajectories obtained by different local trackers. The effectiveness of the viewpoint invariant method for person re-identification was validated on the VIPeR dataset. In addition, we demonstrated the effectiveness of the proposed approach for the inter-camera multiple object tracking on the MCT dataset with ground truth data for local tracking.

This study was established to understand how Arte Povera has affected the contemporary fashion based on the analyses of its characteristics and may provide a prospective view to predict style of future fashions. The results were as follows : 1) “The poverty” shows such characteristics as patch work, intentional mismatch, and tendency to prefer slightly used style. This meaning can be explained as direct expression from a sense of alienation, against to consumer economy, and dual-expression between poverty and wealth. 2) “Anti-formativeness” can be described for misinterpretations of creation, arrangement, and informal silhouette due to distortion of the human body. This expression includes such meanings as against to traditionalism, ignorance of rationality, and disorganization of the concepts between the beauty and the ugly. 3) “Naturalism” indicates as characteristics of use of natural materials and primitive expression. This expression could be generated from adaptation to the nature and desire toward uncivilized society due to skepticism about modern society. 4) “Symbolism” shows such expressions as an isolated feeling from society, and metaphoric sense from specific situations because there are too many applications of imported materials. This tendency can be also explained with the creations of spaces for opened concepts through disorganizations of territory, obscurity, and irregularity.

The objective of this study is to model and simulate the nonlinear lubrication performance of the sliding part between the piston and cylinder wall in a hydrostatic swash-plate-type axial piston pump. A numerical algorithm is developed that facilitates simultaneous calculation of the rotating body motion and fluid film pressure to observe the fluid film geometry and power loss. It is assumed that solid asperity contact, so-called mixed lubrication in this study, invariably occurs in the swash-plate-type axial piston pump, which produces a higher lateral moment on the pistons than other types of hydrostatic machines. Two comparative mixed lubrication models, rigid and elastic, are used to determine the reaction force and sliding friction. The rigid model does not allow any elastic deformation in the partial lubrication area. The patch shapes, reactive forces, and virtual local elastic deformation in the partial lubrication area are obtained in the elastic contact model using a simple Hertz contact theory. The calculation results show that a higher reaction force and friction loss are obtained in the rigid model, indicating that solid deformation is a significant factor on the lubrication characteristics of the reciprocating piston part.

With the aid of extracorporeal circulation, nine dogs underwent orthotopic cardiopulmonary transplantation after preservation of the donor heart in a hypothermic amino acid[glutamate, aspartate] enriched high potassium extracellular solution, and preservation of the donor lung with hypothermic low potassium dextran solution from June 1990 to May 1991. The mean body weights of dogs were 20kg and the recipients` preoperative hematologic and hemodynamic pictures were within normal range except slightly decreased level of albumin and total protein, which was supposed to be due to malnutrition. The following modifications of the original Stanford technique were emphasized: [1] the posterior mediastinum is dissected as little as possible with meticulous hemostasis; [2] the surgical procedure is kept away from the phrenic and vagus nerves; [3] the tracheal anastomosis may be wrapped with recipient`s pulmonary artery flap or surrouding soft tissues. A combination of Cyclosporine, Azathioprine, corticosteroid was used as perioperative immunosuppressive therapy. Postoperatively all recipients could be weaned from extracorporeal circulation, showing favorable vital signs, but within 24 hours, irreversible congetive heart failure, ascites, arrhythmias developed with a mean survival time 13.6$\pm$6.6[n=9, range=6~26] hours. Hemoglobin and platelet counts were significantly[p<0.05] decreased postoperatively, which is thought to be attributed to blood damage by cardiopulmonary bypass and hemodilution. Postmortem finding included multiple subendocardial patch hemorrhage in both atrial and ventricular cavities, pulmonary and liver congestion, and all tracheal anastomoses were intact. Further consideration about quality control of the animal, infection, rejection, the effect of cardiopulmonary bypass on the experimental animal is required to improve the results.

Purpose: This study explored the validity of a new type of thermometer and parent satisfaction with the new device. This 24-hour continuous monitoring smart wearable wireless thermometer (TempTraq^®) uses a very small semiconductor sensor with a thin patch-like shape. Methods: We obtained 397 sets of TempTraq^® axillary temperatures and tympanic temperatures from 44 pediatric patients. Agreement between the axillary and tympanic measurements, as well as the validity of the TempTraq^® axillary temperatures, were evaluated. Satisfaction surveys were completed by 41 caregivers after the measurements. Results: The TempTraq^® axillary temperatures demonstrated a strong positive correlation with the tympanic temperatures. The Bland-Altman plot and analysis of TempTraq^® axillary temperatures and tympanic temperatures showed that the mean difference was +0.45 ℃, the 95% limits of agreement were -0.57 to +1.46 ℃. Based on a tympanic temperature of 38 ℃, the results of validity of fever detection were sensitivity 0.85 and specificity 0.86. Satisfaction scores for TempTraq^® temperature measurement were all > 4 points (satisfactory). Conclusion: TempTraq^® smart axillary temperature measurement is an appropriate method for measuring children's temperatures since it was highly correlated to tympanic temperatures, had a reliable level of sensitivity and specificity, and could be used safely and conveniently.

In Pleuronectiformes, blind-side malpigmentation (hypermelanosis) is common in cultured flatfishes, and is economically important. To understand the mechanism of blind-side hypermelanosis in flatfishes, we examined when the malpigmentation initially occurred, and studied how the symptoms proceeded during early development of the starry flounder, Platichthys stellatus. To assess quantitative pattern changes of blind-side skin, we observed morphological development of the whole body from 22 (total length [TL] $10.0{\pm}0.2$ mm and body weight [BW] $8.8{\pm}0.57$ mg) to 110 days (TL $23.4{\pm}0.7$ mm, BW $193.6{\pm}23.3$ mg) after hatching (DAH), and also examined the malpigmented area rate of blind-side skin and the malpigmented fish ratios. The experimental animals were reared in fiberglass-reinforced plastic (FRP) tanks in water at a temperature of $18.9{\pm}1.9^{\circ}C$ and salinity of $32.6{\pm}0.6$ psu and were fed with rotifer and Artemia nauplii from 22 to 48 DAH, and with A. nauplii and commercial feed from 49 to 110 DAH. As results, the first staining patch seen by the naked eye was observed around the area between the anus and pelvic fin or caudal edge of the trunk at 80 DAH (TL $20.6{\pm}0.5$ mm, BW $112.5{\pm}8.8$ mg). The pigmented area and the pigmented fish ratios were significantly increased from 80 to 110 DAH. These results indicated that malpigmentation on the blind side of starry flounder was initially observed at about 2 cm in length and 100 mg in weight, and the pigmented domain on the blind-side skin was continually broadened by the differentiation of pigmented cells (melanophores and xanthophores) with growth.
