BacJung-pil(百中丸) using in stagnation-syndrome of gi and blood(痺證) is a expience prescription, A female patient diagnosed as wind syndrome of head(頭風), and stagnation-syndrome of gi and blood(痺證) showed severe pruritus, rash and eruption of skin. After the patient took BackJun-Pill, two hours later, We examined her change and witnessed macular papule and severe pruritus. Those symptoms disappeared in 7 days since we administer anti-histamine, steroid and GamDu-TangGamiBang(甘豆湯加味方).

Fused deposition(FD) modeling by Stratasys Inc., is one of the material deposition subfamilies of solid freeform fabrication(SFF) technologies. In this process, build material in the form of a flexible filament, is heated to a semi-liquid state and extruded from a robotically controlled deposition head onto a fixtureless table in a temperature controlled environment. The position of nozzle is computer controlled relative to the base, which allows geometric complex models to be made to precise dimensions. FDM provide what the part was directly tested by the worker. It provide believable data. This study is experiment on surface roughness of part at FDM

Many researches on measurement technology has been made and developed by various methods. Considering the measurement environment with cutting fluid, coolant and the like, contact type measurement methods are mostly used. But contact measurement method has measuring force and so the sensing head becomes worn. By these reasons, we considered sensors not influenced by the former fluid and so can acquire accrate measured values using error compensation due to temperature and vibration. For this purpose, eddy current sensors and Extended kalman Filter Algorithm for processing measured data has been used. In this paper, we present new technology that can be used for measuring workpiece with previous bad environment using direct method and comparison measurement method. We used cylindrical workpieces which were produced by grinding machine for the target.

The hat is the most flexible human head covering. Almost entirely enveloping the hair, it can be simple, pure, elegant and mysterious. Yet it is frequently a highly decorative form of dress. The hat also takes a part in the extension of the area of art as soft-sculpture. My purpose of this thesis is to present diverse artistic hats with natural images by nontraditional materials and natural resources. The reason why I select nature as them is that it is absolutely the origin of life and art. To develop the innovative hat design, I focus on the material to extend the range of art expression. I observe nontraditional materials such as wire, paper and so on that enhance heterogenetic feeling from natural images. The attempt is made to enhance the visual effect by harmonizing the disharmonious feeling. Natural resources such as moss, orange, feather and so on could be adapted to the hat and applied for unique design, which supplies new expression. Therefore, the harmony of natural images and natural resources could avoid dullness, bestow elegance and polish the unique beauty creation of the hat.

Cystic lesions of the neck are frequently encountered on clinical basis. The usual differential diagnosis includes branchial cleft, cystic hygroma, dermoid cyst, tuberculous lymphadenitis, benign detached goiterous thyroid cyst, and Cavitation epidermoid carcinoma. Most of cysts are benign and malignant cysts are rare. The most common form of cystic malignancy in the lateral neck is cystic degeneration of epidermoid carcinoma metastatic to cervical lymph nodes. Cystic neoplasia may result from malingnant changes occurring within the wall of a previously benign cyst Complete head and neck examination on the primary focus is important Especially, when palpation of thyroid is negative, thyroid carcinoma is easily overlooked. Recently, we experienced papillary carcinoma of the thyroid seen as lateral neck cyst. So we report this case with review of literatures.

The dimensions of the human body vary by age, sex, and race. The internal structure and outer dimensions of a body exposed to an electromagnetic field is important for accurate dosimetry. The average physical size of Korean adult males between the ages 18 to 24 was investigated, and a male volunteer was selected whose physical condition is within the physical standards, ${\pm}5%$. Magnetic resonance images and partially computerized tomography images of the volunteer were acquired. The intervals between the transverse images were 1 mm for the head and 3 mm for the rest of the body. About 30 different tissues were manually classified by an anatomist on the raw images, and the segmented images were implemented in the form of a text file appropriate for numerical formulation.

A new laser diode range-finding speedometer is proposed, which is modulated by a pair of positive and negative triangular pulse current superimposed on a dc current. Since a target velocity is directly obtained form a pure Doppler beat frequency measured during the non-modulation period, the new sensor is free from the difficulties due to the critical velocity encountered in the previous sensor. Furthermore, the different amplitude of the two triangular pluses are so adjusted that the measurable range using only one laser head is greatly expanded to 10cm through 150cm, which is about two times that of the previous sensor. The measurement accuracy for velocity of .+-.6mm/s through .+-.20mm/s and for range is about 1%, and 2%, respectively. Because the new sensor can be operated automatically using a microcomputer, it will be useful for application of a 3-D range image measurement of a slowly moving object.

In recent years, the study of self-assembly peptide used in drug delivery system has been attracted great interest from scientists. In the category are self-assembly peptides in the structure either with one hydrophobic surface and another hydrophilic or a hydrophobic head and a hydrophilic tail. Here, we focus on a novel designed peptide EYK with double amphiphilic surfaces, investigating on the capability of peptide as a carrier for hydrophobic compound model pyrene. The fluorescence data presented the dynamic process of the transfer, showing that the pyrene was in the crystalline form in peptide solution, and molecularly migrated from its peptide encapsulations into the membrane bilayers when the peptide-pyrene suspension was mixed with liposome vesicles. The results indicated that the peptide EYK could stabilize hydrophobic pyrene in aqueous solution and delivered it into EPC liposome as a potential carrier.

Nowadays, most small form-factor drives adapt a load/unload mechanism and the flying height of the head becomes more and more low. So, the load/unload velocity also becomes one of the important factors to ensure the reliability of the load/unload operation. To control the load/unload velocity accurately, velocity sensing is most important because there is no special velocity sensor during the load/unload operation. In this paper, we proposed a very practical method that measures the velocity from the BEMF voltage of a VCM. Then, the proposed method is applied to the load/unload velocity control using 2.5' drives in order to verify its usefulness.
