Botryoid odontogenic cyst (BOC) is considered a rare multilocular variant of the lateral periodontal cyst. In this report, a 67-year-old male visited with chief complaint of severe mobility on mandibular incisors. Multilocular radiolucent lesion was seen from the right premolar to the left premolar area, involving almost the whole mandible. Histologically, the botryoid odontogenic cyst showed focal nodular thickening of the lining epithelium. These thickening often showed swirling appearance of the cells. Cyst enucleation and bone graft on mandible anterior and both body area were performed under general anesthesia, and postoperative healing was favorable without recurrence.

This research focuses on the development of a fast datum transformation model to be used in GIS that utilizes real-time data transformation. Instance, when a GIS data constructed according to a datum is conformed to another datum, instead of transforming the axes of the original data, the data is transformed right before the results are reflected on the monitor. In this research, the prospects of calculating transformation parameters for every grid cells on the area based on two-dimensional conformal transformation model in order to decrease real-time datum transformation time while maintaining a high accuracy has been investigated. Research results showed that for a fixed area, the accuracies of the two-dimensional conformal transformation and the three-dimensional datum transformation, which requires more computing time, were almost equal and fast transformation speed, high accuracy real-time datum transformation is made feasible by implementing the grid-divided two-dimensional conformal transformation model.

This study is aimed to personally measure the body of physically handicapped women and compare the measurements to the results of the fifth project to investigate the measurements of the body of Koreans, identity the differences in the measurements in accordance with the subjects' handicap types and age, and find the characteristics of their physical figures, with a view to propose basic data for developing clothes suitable to the body of physically handicapped people. The findings of this study are summarized in the following: 1. There were significant differences in the measurements of the subjects' shoulder width, breast circumference, waist circumference, hip circumference, armpit circumference, left and right upper arms' circumference, length between front walls of the armpit, and length between back walls of the armpit after the subjects' handicap types were classified into paralysis of the lower half of the body, cerebral apoplexy, cerebral palsy, and amputation and the differences in the subjects' bodily measurements were compared and analyzed. 2. The shoulder width gradually increased for those in their 50s or younger while that of those in 60s or older is almost the same as that of those in their 30s. The waist circumference gradually increased in all the subjects. As a result, the present author concludes that the body of physically handicapped women increases the same way as the body of ordinary adult women does in its circumferential measurements as the subjects grow older.

This study examines the variation in diagrams of the kidney, and the effects on location of the Life Gate as a result. My study analyzes diagrams of kidney form and location, such as appearance, the vertebral spine, ShenXi, and "Life Gate", and also explores the causes for such variations. The kidney is commonly described as having the shape of a bean, which throughout medical history has showed almost no variation. The spine was initially described with a total of 21 vertebrae, and later with a range of 19-25 vertebrae. Regarding the height of kidney in relationship to the spine, it was initially described as beginning at the 14th vertebrae, and later changed to the 15th or 17th vertebrae. However, there have been no changes in the perception of the height of kidney. Initially, the location of the Life Gate could not be identified. Three different suggestions of its location were found throughout historical literature, including: (1) at or within the right kidney; (2) between two kidneys; and (3) between 14th-15th spine. There were also variations noted in the process of copying diagrams of kidney in many books not only because the work of copying was not precise, but also because each medical practitioner had a different interpretation of the kidney's form and function in Traditional Korean and Chinese Medicine. It appears that some practitioners may have been influenced by their understandings of theory of Life Gate.

The purpose of this study is to analyze the physiological effects of non-elastic corset on women's health and pain through measuring the clothing pressure, subjective pressure sensation, blood velocity and metabolism. 5 women in their twenties were picked as our subjects, their average size being 85cm at bust girth, 69 cm at waist girth. With the subjects each wearing a corset, we are testing in artificial environment with a treadmill according to the planned exercise procedures. The average pressure of the corset is 0.938 kPa (maximum 3.006 kPa at 45 degree front bowing), which is 10.2 times higher than the control group, averaging from 9.3 times higher at resting, 11.4 times at walking, 11.1 times at running. The effect of corset pressure on the physiological responses of the body is increased more when exercise than when resting. Clothing pressure increased in the order of the postures: sitting > standing with 45 degree bowing > standing. They experienced a high level of tighten discomfort of 5.6 in the scale of 1.0 to 7.0 due to the high pressure of the corset when resting, after intense exercise the level increased to 6.0, while without corset the level increased 1.7 to 2.2. With corset on, the blood circulation did not increase even though when the body exercised and blood flow became unbalanced making great gaps between both at the right and left finger tips. Perspiration of chest and back decreased 37.3% when wearing corset; 27.5% at resting, 56.7% at walking, 25.8% at running, and 39.0% at recovery. With corset on oxygen consume and metabolism increased 9.0%, 7.9%, respectively, which means the corset makes the body uncomfortable. Lung volume exchange VE decreased almost 4.1~7.3% with corset on and $VCO_2/VO_2$, RER and total volume in lung, VT also decreased too, which means the digestion of stomach and lung function are inhibited due to the high corset pressure.

This study was carried out from 1 November 2000 to 29 March 2001 and objects are 20 college students located Taegu area. Also to determine effect of ultrasound and manipulation on temporomandibular joint pain and limited range of motion. Results obtained were as follows 1. The mean value of open mouth rate are ultrasound group more high than manipulation group between two group until first visiting treatment, but after second visiting treatment tend to increased manipulation group. We are find out that mean are reciprocal action between two group and visiting times 2. Rate of open mouth are almost same between two group, but after 3 times, manipulation group are more effect than ultrasound group. There are no significantly difference(P<.005) between rate of open mouth due to the treatment times(P<;.ool ) and two group. 3. The mean value due to the treatment times have tendency to increased on the left and right lateral motion mean. but no statistical significantly difference between two group. Also two group have effects according to treatment times, but no significantly difference between two group.

A scanning electron microscopic stuey on the glochidial encystment study on the golchidal encystment and excystment of Anodonta fukudai on Acheilognathus yamatsutae, a common natural hostfish, was conducted. The glochidium easily attached to the unscaled surfaces of the host fish such as the fins, lips, and the wall of the buccal cavity. For this study, the fins infected with the glochidia wer mainly observed in a series. The process of encystment was slowly progressed, for 21-25 hours for the early cyst and for 2-4 days for the thick walled cyst. The process of excystmint was visually detected on the 12th day since the attachmint was occurred. The first visible sign was a little tear of the cyst wall covering the hinge and marginal zones of the juvenile clam and once the little sign was appeared the progress of emerging and dettachmint of the juvenile clam from the host was finished relatively in short time. During the process of the encystmint, the cells participationg in covering the attached glochidirm were seened mainly supplied by migration from the surroundings. the shapes of the cells migrating and covering the glochidium were considerably changed and the surface structures of the cells lost their normal pattern of the surface ridges. The unstable forms of the cells were observed almost all throughout the period of the glochidial attachment. No cells of the host epithelium, which were still attached to the juvenile clam energing from the cyst, were observed. The most juvenile clams escaped from the cysts were a little bigger than the glochidia and they were still possessed of the golchidial hooks even though much degenerated. The first growth line was appeared on the shell valves of the juvenild clam when observed right after dettachment.

With the coming of the digital era, encryption has become common in everyday life. Almost anyone can easily acquire encryption software and use it to prevent unwanted third parties from accessing one's private information. However, the spread of encryption has also seriously hindered law enforcement during the investigation of cybercrimes, which hides incriminating digital evidence in encrypted hard drives and files. Therefore, many countries have attempted to compel criminals to decrypt encrypted evidence and it has been inevitable to examine privilege against self-incrimination as basic right on the side of constitution. This study analyzed the past court decisions on the issue of compelled decryption in the US and whether the Government can compel a defendant to disclose his password in Korean legal system on the constitutional side. Finally, this study suggests an approach to create a legal procedure to make it a crime for a suspect or defendant to refuse to disclose his password to law enforcement for criminal cases in Korea.

This study is a design study related to the application of 3D printer technology for garment printing. Knitting, which used to be a home industry in the early days, originally comes from hand-knitting. This evolved with various personal devices as a small job for the self-sufficiency of early European housewives. In addition, since the Industrial Revolution, mechanical production entered the mass production mass supply system, and various apparel products were provided to consumers in accordance with mass standardized dimensions. This is similar to the development process in Korea. In addition, it has formed a considerable market with the situation that it can produce and supply apparel products at low labor costs of first-generation Namdaemun and Dongdaemun merchants. As the production shifted to the Southeast Asian region due to the increase in labor costs in the domestically developed social situation, the production of garment products in Korea is now almost 5%. As a result, apparel-related production facilities and related companies are constantly moving to other countries to move production facilities sensitively due to rising labor costs. Recently, smart factory automation has been planned to explore new possibilities. In addition, in recent years, with the evolved appearance of consumers, the appropriate supply of the right amount of production has appeared, and the 3D printer applied to personal garment output has attracted considerable interest in the customized market. Therefore, in order to become a new hope and a small addition to various clothing workers, this study conducted related research on the following 3D printers for clothing output and attempted to proceed with a new design.

Angiosarcomas are rare tumors, seen most commonly in the skin and soft tissue of head and neck legion. But it has been described in numerous body sites including thyroid, breast, liver, spleen, bone, etc.. Their biological behaviors depend on the microscopic grade, site of origin, and multifocality. We report the unique cytological features of an angiosarcoma in pleural fluid. A 61-year-old woman presented with a 6 month history of dyspnea on exertion and chest pain. Chest computerized tomography(CT) revealed multiple subpleural small nodules in the right lung and widespread all space consolidation and pleural effusion in the left lung. CT of liver revealed multiple small low attenuated lesion. The smears obtained from pleural fluid showed hypocellularity with a hemorrhagic background. The tumor cells were highly pleomorphic oval or spindle in shape and presented singly, in loose groups, in knitted syncytial aggregates, and in acinar pattern. Their nuclei had vesicular chromatin with delineated, thick nuclear membranes and occasionally a large eosinophilic, prominent nucleolus. The cytoplasm was plump, thin or protected in spindly fashion. Almost ail tumor cells showed variable sized intracytoplasmic vacuoles and their nuclei were sometimes crescentic by a huge vacuole. Occasional binucleated tumor cells and mitotic figures were present. Cellular debris and streaky materials were identified. Needle biopsy specimen from the pleura revealed anastomosing slit-like spaces lined by pleomorphic tumor cells. The tumor cells showed a strong reactivity for CD31 and vimentin and focal weak reactivity for factor VIII-related antigen.
