Midfacial retrusion is one of characteristics of cleft patients due to underdevelopment of the midface. In this case, Le Fort II advancement is indicated. But there has not been reported on intraoral approach to Le Fort II osteotomy for correction of midface, which traditional technique resulted in facial scar. To overcome the problems, Le Fort II osteotomy via only intraoral approach named 'Intraoral Le Fort IT osteotomy' was developed by Choung in 1994, this technique was applied to cleft patients. A new technique of Intraoral Le Fort IT osteotomy for correction of midface in cleft patients was successfully carried out with good results. This technique showed no noticeable relapse nor complications, which is reported.

An additional consideration for using general Induction Motor are about copper loss by harmonic component of source, and increase of iron loss due to switching frequency in semiconductor devices, so that these losses come to be significant elements on design for motors used for variable V/F. In this paper, therefore, the effects of the losses are discussed, in the case the source is generated by square wave and PWM Inverter.

Angiolymphoid hyperplasia with eosinophilia(ALHE) is a benign subcutaneous lesion that primarily affects head and neck region. It is characterized by single or multiple nodules in the subcutaneous tissue associated with eosinophilia in the peripheral blood. Kimura's disease, originally reported by Kimura et al., is similar lesion with ALHE in the clinical and histopathological aspects. There has been considerable controversy about the relation between Kimura's disease and ALHE. In Korea, 26 cases of Kimura's disease and ALHE have been reported since 1975. We present a case of recurred ALHE occurring on the left cheek in a 58-year-old woman. Including this case, we summarized all cases that were reported as Kimura's disease or ALHE in Korea through literature review. We also give an outline of clinical and histopathological characteristics of cases reported in Korea.

In general, shape optimization design of the flow system has done to obtain the effects, which are required in the engineering fields. Most of these designs are accomplished by empirical or numerical analysis. But, in empirical analysis case, it is difficult to obtain an optimal shape in the feasible design region. And, in numerical method case, it usually needs many design parameters, because of the required object-function. In this paper, we present a newly numerical analysis, the growth-strain method having only one design parameter. That optimizes a shape by distributing a design parameter such as dissipation energy to be uniformed in the flow system. Also, we apply this shape design process to the three-flow systems, and then we identify that the resulting shape approaches the known optimal shape in the numerical values. Consequently, we confirm that the proposed method is very efficient and practical in the shape optimization of the flow system.

The study was clinically performed with the 128 out patients of dermatic disease who had visited the Dept. of dermatology, Dongzhimen Hospital, Beijing traditional medical college from May 2nd to February 14th 1996. The results were as follows. 1. The dermatologic findings which showed higher incidence in this study were Acne of Melasma 27 cases($21.0\%$), Psoriasis 25($19.5\%$), Eczema including Contact dermatitis 21($16.4\%$), Seborrheic dermatitis including Alopecia of hair 12($9.3\%$) and Urticaria 11($8.5\%$). 2. The sex ratio of male to female was 4.5 : 5.5. The peak incidence of age group was 30-39($21.8\%$). 3. In the duration of disease, 37 cases($28.9\%$) were between 1 year and 5 years. 27($21.1\%$) were over 10 years. 4. About the single herb drugs, they are Angelicas gigantis Radix, Paeoniae Radix and Salviae Radix in order of frequencies. In the case of pill type, Danggui gosam hwan. Chunggan hwan. Whaeo hwan and Shinnongjiyang hwan are most frequently used. In the case of topica, Whangyeongo, Juachanggo and Soeungo are used in high frequencies. 5. For the test and surgical treatment KOH surgical treatment of Molluscum contagiosum in 8 cases and the bloody treatment of Chronic psoriasis in 3 cases.

Operations using the da Vinci robot have performed in for many surgeries, but the adoption of robotics to general thoracic surgery has been slow. The patient (age 74, male) visited our hospital complaining of hiccups and dysphagia. The CT scan and endoscopic biopsy revealed esophageal cancer (squamous cell carcinoma). We performed transthoracic esophagectomy using a da Vinci robot and this was followed by gastric tube mobilization via laparoscopy. Cervical esophago-gastric anastomosis was done using the hand-sewn method. The gastric tube was brought into the neck through the retrosternal route. The patient was discharged without any complications. We report here on a case of successful da Vinci robotic esophgagectomy.

7 cases of Acute Gastric Anisakiasis have been reviewed at the Department of Internal Medicine. Yeungnam University Hospital from March, 1983 to December 1986. 1. Of 7 cases, the ratio of male and female was 3:4 and the age 30s occupied most (5 cases) the 50s' followed (2 cases). 2. Chief complains were in order of epigastric pain (6 cases), vomiting (3 cases), Nause (2 cases), Ulticaria (1 case) & epigastric fulling sensation (1 case). 3. In all 7 cases, the causative fish is Astroconcer myriaster. 4. The onset of symptoms was observed within 5 to 7 hours after eating the causative raw fish. 5. Gastrofiberscopic exam was undergo within 18 hours since onset of symptoms. 6. The gastrofiberscopic findings were gastric mucosal edema and redness in all 7 cases. One case also had mucosal erosion. The involved sites of the stomach were in frequency of order, the body (5 cases), the antrum (2 cases). 7. The symptoms of the patients relieved spontaneously without medical treatment after the extraction of the larva with biopsy forcep during gastrofiberscopy. 8. In Korea, many people take raw fish and there may be many patients of Anisakiasis so if much concern and careful observation are paid to whom, with severe cramping epigastric pain after taking of raw marine fish in about 10 hours, we could find out and confirm more patients suffering from Anisakiasis by immediate endoscopic gastrofiberscopy.

CSD is Active RFID based Container Security Device which is proposed by the U.S Department of Home Security. It is mounted inside the container to sense opening of the container door. ConTracer is the CSD which is developed in this research whose major features are sensing door opening status as well as history inquiring on internal environment and shock to the container by mounting the temperature/ humidity/ shock sensors. Moreover, its RFID frequency bandwidth uses 433MHz and 2.4GHz to correspond actively to the frequency used by different countries. This paper introduces the development trend of CSD, compares the ConTracer which is developed thru this research and other company's CSD, and introduces CSD System which is designed and established using ConTracer. Finally, the implemented CSD System is verified by applying the demonstration service to container distribution between Korea and China.

Pleuropulmonary blastoma (PPB) is an unusual intrathoracic blastoma presenting in childhood and charac-terized by a biphasic neoplastic population of undifferentiated, small round blastemal cells and larger spindle-shaped sarcomatous cells with entrapped benign epithelial-lined structures. We experienced the cytologic features of PPB in imprint smear from the pleural-based huge mass of the middle lobe of the right lung in a 4-year-old boy. The smears showed high cellularity composed of small ovoid blastemal elements and scattered spindle mesenchymal tumor cells. Lobectomy and pathologic investigation confirmed the diagnosis. PPB seems to be a tumor in which accurate diagnosis may be achieved by cytoiogy if appro-priate clinical information were given. Timely and accurate diagnosis of PPB by cytology paves the way for attempting preoperative treatment in future cases.
