In this paper, we implemented a smart mirror that helps users to measure the results before the procedure by reflecting various hairstyles on the head. When the camera is used to capture a face in real time and recognize the face, the stored hair image is uploaded to provide a virtual image. In addition, the high production cost, which is a problem of the existing smart mirrors, was reduced by using Raspberry Pi, Open CV, and half mirror film, and various functions were implemented through touch control. It is also designed to provide information such as weather, calendar and time.

In this study, the earth retaining structure using a row of piles considering plastic flow of the ground is suggested for shallow excavation works instead of conventional anchored sheet-pile wall method in the marine clays with high groundwater level. The behavior of the earth retaining structure using a row of piles is precisely observed during excavation by inclinometer and piezometer installed in opposite to the excavation side. As a result of field measurement, it was found that the behaviors of the piles and the soil were influenced mainly by slope of excavation face, interval ratio of piles, fixity condition of pile head, and stability number, etc. The earth retaining structure using a row of piles is ascertained for workability, stability, and economical construction on the soft ground having no adjacent structures.

For having good therapeutic value, putting the ideal of diagnosis and treatment based on overall analysis of symptoms and signs[辨證施治] into practice is very important, so the Eastern Medicine's peculiar diagnosis without interference by the western medical diagnosis is very important. The peculiar method of Eastern Medicine's diagnosis is four methods of diagnosis(四診法), a joint term for inspection, auscultation and olfaction, interrogation, pulse feeling and palpation. In the process of interrogation[問診], from analyzing the perspiration phase, doctor can get various physical information. Especially perspiration from particular region can be a clue for founding focus or cause of disease. This thesis divide the phase of perspiration into eight bodily region, perspiration from all body, head, face, back, chest and armpit, stomach, pubic region and lower part, hands and feet, and inquire the possible causes and principles of these perspirations. In conclusion, the regional perspiration can be a clue point out the origin of fever and condition of Gi(氣) flow. Perspiration from head, back, chest and armpit, hands and feet means that certain fever cannot extend to the outside of body, and at the same time, means the Gi(氣) flow of outside is being intercepted. So the perspirations from that region become an object of medical treatment.

Myopericytoma is a benign tumor that is composed of myoid-appearing oval to spindle-shaped cells with a concentric perivascular pattern of growth. The tumor is morphologically heterogeneous and can exhibit a broad histologic spectrum. We describe a case of multiple myopericytoma occurring in the head and neck skin region with involvement of the parotid gland where it is known to occur very rarely. A 40-year-old woman noticed multiple enlarging, painless, round-shaped masses on her left cheek. The patient had experienced a similar lesion of the same area 8 years earlier which was completely excised and the pathological diagnosis was spindle cell type myoepithelioma. On a computed tomographic image, one mass involved the superficial parotid gland and was well encapsulated. Excision of the facial masses and superficial parotidectomy with facial nerve preservation were performed. A diagnosis of myopericytoma was established in light of the immunohistochemical pattern with the histopathological findings. Over the 4-year follow-up period, there was no evidence of recurrence. As many perivascular myoid neoplasms share common morphologic features with myopericytoma, we should consider the differential diagnosis, and confirm the histological findings with appropriate immunohistochemical staining. After identifying myopericytoma, it should be treated with wide surgical excision to prevent local recurrence.

Mucinous Eccrine carcinoma (MEC) is a rare malignant tumor related to the eccrine sweat gland and is commonly located on the face, especially around the eyelids and scalp. Most of these tumors are diagnosed at age 40's to 60's and exhibit a wide variety of patterns in addition to the general appearance previously reported. MEC is difficult to diagnose clinically, but can be diagnosed by accompanying biopsy. We present the case of a 75-year-old man who complained of a gradually growing Left lower lid tumor of duration one year. Initially, the tumor was mistaken for an epidermal cyst and treated by surgical resection. However, biopsy findings resulted in a diagnosis of Mucinous Eccrine carcinoma. Therefore, we performed wide excision and flap reconstruction surgery. In a one year follow-up examination, the patient achieved successful functional and aesthetic results without regional or distant metastasis and recurrence.

Connective tissue massage(CTM, Bindegewebs massage) are developed and named by Mrs. Elizabeth Dicke, a German physical therapist. The CTM is used primarily for internal disorder such as myocarditis, coronary insufficiency, high blood pressure, functional stomach and intestinal disorders, inflamma-tion of the gallbladder, and hepatitis, arterial circulatory problems, venous disorders, headache, particularly trauma to the head, and some gynecologic disorder, etc. Which is performed with special stroking technique of the subcutaneous tissue of the trunk, extremities, and face. The mechanism of effectiveness of CTM is based on a viscerocutaneous reflex. The stroking stimulates the nerve end-ings of the autonomic nervous system. The impulses activated by stroking travel to the sympathetic trunk and the spinal cord and brain, which causes a change in reaction susceptibility. The most important for apply CTM is necessary to know the reflex zone (Head's zone, Mackenzie's zone and Dicke's connective tissue zone). Dicke's connective tissue zones are only found by the special dia-gnostic stroking. Because the connective tissue zones no discomfort when unmanipulated, and thus the patient is unaware of them. It is characterized by diagnostic stroking that causes a sharp pain in the tissue. As a general rule, all treatment are preceded by the basic stroke from the level of the coccyx to the first lumbar vertebra and each stroke is done three times. The right side is done first, then the left side.

A 14-year-old male patient was referred to us for evaluation of Right TMJ clicking sound and mandibular deviation during mouth opening. On examinaaation, protrusion and lateral excursion was also restricted. Radiographs showed hook-like curved elongation of Right coronoid process with limitation o right condylar translation. His past medical and dental history was noncontributory. This patient underwent an extraoral coronoidectomy and the specimen revealed coronoid process malformation mimicking condylar head. Microcoically, the specimen discloses mature bony trabeculae. At postoperative 5 days, physical therapy was instituted. At present, this patient could open his mouth well with any clicking sound and mandibular deviation. The asymmetric face of this patient is expectated to be corrected by periodic observation and remained growth porential. If not to be corrected, orthognathic surgery will be done.

Xeroderma pigmentosum is a rare autosomal recessive disease, related to defects in DNA repair mechanism. It presents skin lesions on sun-exposed areas, leading to various skin cancer. Skin lesions can be treated with cryotherapy, skin resurfacing, 5-FU, Imiquimod, topical T4 endonuclease V, radiotherapy and genetic therapy, but invasive skin cancer should be treated by a surgery. We report a 12-year-old female xeroderma pigmentosum patient with recurrent basal cell carcinoma successfully treated by skin grafting. In that there is no cure for this disease, prevention and patient education is most important.

The turbocharger, to decrease the harmful exhaust gas(CO, HC and etc.) and $CO_2$ emission as well as the increase of the engine output, would be an useful method for engine downsizing. Therefore the thermal endurance of turbine blade, the lubrication of turbine shaft and the engine knock according to the supercharge of the inlet air, had been studied. And there had been much progress in these research tasks to be achieved a breakthrough. But a study on the built-in WGV of a gasoline engine for a passenger car which may effect on the engine performance, is few. In this paper, the effect of the embedded WGV on the engine performance was performed through the endurance test, which was conducted more than 300 hrs using the 4 stroke, 1998 cc, water-cooled engine. To sum up the major results, there were an abrasion in the area of the WGV head edge and the thermal deformation on the WGV head face, These phenomena led to reducing the boost pressure which caused the reduction in the volumetric efficiency of the engine. It resulted in decreasing the engine power gradually during the life cycle of the embedded WGV.
