Objective : This study investigated results of treatment of Atopic Dermatitis(AD) patients diagnosed as damp-heat type with herbal medicine and wet dreesing. Method : Six AD subjects diagnosed as damp-heat type were selected from the outpatient department of East-West Neo Medical Center in the period of Dec. 2006 to Feb. 2007. Each subject was treated with herbal medicine and wet dressing. Severity Scoring of Atopic Dermatitis(SCORAD) was used to evaluate the effect of treatment and pictures were taken of the Atopic dermatitis lesions. Result & Conclusion : We observed improvement on SCORAD score, especially intensity score of damp-heat type when they were treated with herbal medicine and wet dressing. However, it is less effective and AD often recurs in case of chronic adult-type AD. In addition, nipple eczema in some patients has showed a tendency to improve slowly and recur easily compared to other lesions.

The corneal formation of compound eye of Pieris rapae L., which was mostly made during pupal stage, was morphologically investigated with light microscope, scanning electron microscope and transmission electron microscope. The regeneration of the microvilli were found on the surface membranes of corneagen cells and retinular pigment cells of preommatidium after apolysis pupal cuticle. The microvilli were finally differentiated to corneal nipples of the ommatidium. The corneal cuticle was generated on the superficial layer of the preommatidium from corneagen cells and retinular pigment cells. The corneal process was also formed under the cuticular layer from the corneagen cells. The pore canal was appeared within the cuticular layer and connected with the retinular pigment cell as if the root of interommatidial hair was connected. The interommatidial hair was projected randomly among the ommatidial facets and cornal nipple was arrayed regular on the ommatidial facets. The cornea was convex lens and the refracting power by its convex shape was 4 diopter.

The stress behavior analysis of a-rings and packing for a LPG filling unit has been presented using a finite element analysis technique by non-linear MSC/MARC program. The sealing performance and endurance of a-rings and packing are affected by working conditions such as filling pressure, friction coefficient, compression ratio, and material properties. The elastomeric polymers of O-rings and packing are nitrile butadiene rubber (NBR) and polytetrafluoroethylene (PTFE), which are selected as proper materials of a-rings and packing based on the stress analysis results. The calculated FEM results showed that the proper material of O-ring is NBR as a secondary sealing component and the recommended material of packing is PTFE as a primary sealing unit during a LPG filling process.

It is necessary to analyze the mechanical behaviors of the power steering hose, which must play a proper role under severe operating conditions, in order to prepare a preventive measure fur contrary effects expected in unfavorable circumstances. In this paper, the stress and deformation characteristics of the hose components such as rubber, sleeve, nipple and reinforced braids during the swaging process, are analyzed using the finite element method. Contact conditions identical to the manufacturing process are taken into account, and the material properties based on experimental data are used in the analysis. Investigations into the mutual relations between the manufacturing conditions and the hose performances are done with respect to the jaw stroke on the basis of the stress and strain values of the hose components after swaging process.

Purpose: Mondor's disease is commonly known as a benign breast condition after augmentation mammaplasty, and some authors have also reported its association with other breast surgeries such as reduction mammaplasty or axillary lymph node biopsy. Here we report two cases of Mondor's disease after immediate breast reconstruction with silicone implant. Methods: Two women, 51-year-old and 36-year-old, underwent immediate breast reconstruction with silicone implants after nipple-areolar skin-sparing mastectomy. Results: Subcutaneous cord-like firm lesion appeared on upper abdomen, axillary area following surgery. The lesion was painless and spontaneously subsided with no medications. Conclusion: To our knowledge, this is the first report of Mondor's disease developed after immediate breast reconstruction using silicone implant.

The full-field digital mammography (FFDM), which has been known as a digital breast imaging system, carries out more outstanding performance than the screen-film mammography in overall image quality, skin & nipple, description of pectoral muscle and expression of micro-calcification. Thus, in this thesis, I perform experiments for both the enhancement of image quality and accurate estimation of the result in question, when detecting the very tiny-sized lesions in mammography. The image of digital breast X-rays is the important diagnostic tool for detecting early breast cancer and micro calcification lesion. The experiment of how much compression rate has an effect on the result of diagnosis in the case of microcalcification lesion, with JPEG2000 40:1 compression and over 50% enlargement led to obscure or definitely unacceptable diagnostic results is performed. And in another study of assessment of PSNR degree. I recognized the importance of standardized management system in mammography, where not to mention the accurate reading of the image has the most crucial role in diagnosis

There prevailed lymphocystis disease with 1 to 2cm in size in the skin and pins of cultured Sebastes schlegeli in fish farms in Tongyoung-gun, Sanyang-myeon, Kon-ri from summer, 1987 to fall, 1988. Though there were some difference between each fish farm, this disease prevailed widely from immature fish to mature fish, less than 10cm to 30cm in body length with about 8 through 80% of infection rate. Sebastes schlegeli with the lymphocystis disease showed combined nipple-shaped mass by doubly, triply propagated lymphocystis. But the author considered that lymphocystis disease was not a direct cause of death of Sebastes schlegeli, the fish showed marked inflammation by seconary infection of pathogenic organisms.

Transsexual individuals with gender dysphoria or gender identity disorder are rare, with a prevalence reported to range from 0.002% to 0.014%. Studies have shown that mastectomy yields significant improvements in body image and self-esteem in female-to-male transsexual patients. In patients with grade III breast ptosis, mastectomy with a nipple-areolar complex (NAC) graft is the most commonly used technique, although it has several disadvantages. In the case described herein, a bilateral mastectomy preserving the NAC in an inferior pedicle was performed. Additionally, a thin superior thoracic dermal-fat flap was preserved and eventually sutured at the previous inframammary fold, preventing an inverted T scar. This case shows the advantage of this technique for preserving the blood supply and innervation of the NAC, with a low hypopigmentation risk. Furthermore, in this technique, the patch effect does not impair the results of the NAC graft, and there is no need to use an inverted T scar that may result in thoracic feminization.

A combined cartilage holder and crusher is described that allows the surgeon to hold, crush, morselize, and suture a single piece or stack of cartilage graft without letting it slip. The customized slit-shaped jaws allow adequate room for the suture needle, while the serrated surfaces hold the cartilage firmly. The use of this instrument is advocated primarily in rhinoplasty for manipulating and suturing a small cartilage graft or a stack of grafts. The use of this instrument may be extended to aesthetic or reconstructive cases where cartilage grafts need to be sutured or shaped, as in eyelid, ear, and nipple reconstruction.
