1. In oriental medicine, the case of sinusitis can be explained, not only external invasion such as PUNG HAN(wind-cold), PUNG YUL(wind-hot), SHUP YUL(damp-heat), but also functional disorder of internal organ such as spleen(脾), lung(肺), kidney(腎) The western medicine classified the cause of sinusitis as two factors. That is bacterial infection factor-Haemophilus influenza, streptococcus pyogeues, streptococcus pneumonia- and viral infection factor-Rhinovirus, parainfluenza, Echo28, Coxsacki21, Sinusitis is complicated to allergic rhinitis, chronic otitis media purulent, chronic tonsilitis, sinubronchitis. On the condition of nasal septum deformity, turbinates deformity, nasal septum deviation, sinusitis can be developed. the predisposing factors of sinusitis is swimming, air pollution, malnutrition, shortage of immunity.2. According to survey, sinusitis occurred that children from 4 to 12 years old and from 5 to 7 years old occupied 70% 3. From the past history data, they experienced chronic tonsillar hypertropy(20%), otitis media, atopic dermatitis, allergic rhinitis, bronchial asthma, pneumonia, bronchiolitis, chronic sore throat, urticaria, milk allergy in sequence. 4. the symptoms of sinusitis is nasal obstruction, postnasal dripping, purulunt(yellow)or white discharge, cough, nose bleeding in sequence. nasal obstruction take the portion of 95%, postnasal dripping 65%, night time or early morning cough 60%. 5. The suffering period of sinusitis is 6 month minimum, 4 years maximum, most cases are included in a year. The suffering period of children was shorter than adult. 6. Diagnosis depend on inspection of nasal cavity, postnasal dripping, X-ray finding. 75% of patient(15case) showed both maxillary sinusitis, 25%(5cases) showed left or right maxillary sinusitis. 7. Treatment of oriental medicine, consist of Herb-medicine, acupuncture and exposing of Lazer beam. Kamihyunggyeyungyotang(加味荊芥蓮翹湯) is administered mainly as the medical therapy, Kamigwaghyangjeungkisan(加味藿香正氣散) Kimizwakwieum(加味左歸飮), Kamihyangsosan(加味香蘇散) is administered for a additional symptoms which occurred by influenza recurrence. Kamijeonxibackchulsan(加味錢氏白朮散) is administered to treat gastro-intestine trouble patients who have sinusitis. 8. The period of treatment is varied with patient conditions and X-ray finding. The minimal period is 35days, maximal period is 202days. So it took about 86days in average and about 50% of patient(10cases) is recovered in one or two month.

Lentiviral vector system is efficient vehicles for the delivery of exogenous genes, and it is generally used in the generation of transgenic chickens. In this study, we used recombinant lentiviral vectors to generate transgenic chicks that express the human superoxide dismutase-3 gene driven by the chicken ovalbumin promoter. It is well known that superoxide dismutases(SODs) are believed to play a crucial role in protecting cells against oxygen toxicity. There are three forms of SOD proteins: cytosolic Cu-Zn SOD, mitochondrial Mn SOD, and extracellular SOD(SOD-3). The recombinant lentivirus containing the human SOD-3 gene was injected into the subgerminal cavity of freshly laid eggs. Subsequently, the embryos were incubated to hatch using phases II and III of the surrogate shell ex vivo culture system. From 341 injected embryos, the 78 chicks hatched after 21 days incubation. The hatched chicks were screened for the human SOD-3 gene by using PCR. Two of 47 male chickens that survived to sexual maturity contained the human SOD-3 gene in their semen. These results showed that our transgenic chicken generation system was completely established.

Five cases infected with Rhabditis sp. were detected in a survey to examine the stool specimens from rural primary school children. A large number of the larvae of Rhabditis sp. detected by the direct cellophane thick smear were cultured by the alter paper method. The eBamination was carried out in April through June, 1980 in Tangjeong-Myon, Ahsan.Gun, and in September 1983 in Sandong-Eup, Yeongwol-Gun. The results obtained in this study were as follows: 1. Prevalence: Out of 925 children, 5(0.54%) children were found to be positive. The number of the detected larvae was 110/0.1gm of feces in case 1, 35 in case 2, 130 in case 3, 86 in case 4 and 62 in case 5. 2. Larvae: The larvae were prepared by means of the direct fecal smear and measured by a micrometer equipped in the microscope. Twelve (12) through 15-day old larvae in culture were $197.1{\mu}{\textrm{m}}$ long in average, and the maximum size of the matured stage larvae was $884.0{\times}25.9{\mu}{\textrm{m}}$. However, the length variation was ranged as 173.0 to $884.0{\mu}{\textrm{m}}$. 3. Adults: The size of clubbed adult female was $1, 357{\mu}{\textrm{m}}(1, 176~1, 419)$ in length and $80{\mu}{\textrm{m}}(79~82)$ in width. Length of buccal cavity was $33{\mu}{\textrm{m}}$. A long cylindrical esophagus($273{\mu}{\textrm{m}}$) of the worms with a valved posterior cardiac bulb and with median bulbar swelling was morphologically indicated. Ditance from mouth to vulva was occupied 58% of body length. Male worm was $1, 006{\mu}{\textrm{m}}(890~1, 148)$ in length and $49{\mu}{\textrm{m}}(48~49)$ wide. Caudal alee of bursa and spicules ($75{\mu}{\textrm{m}}$ in length) were well developed. 4. Eggs: The oval shaped eggs in the female uterus, when cultured, were $66{\times}56{\mu}{\textrm{m}}$ in sixte, and the eggs laid by the adult could not be detected. So, reproduction might be thought to be ovoviviparity. 5. The five cases were re-examined during the period from the 1st to the 3rd week after stool examinations, but Rhabditis sp. were detected again in 4 cases in 1st week. When they were examined in 3rd week, larvae could not be detected. So, it was thought that the infection of Rhabditis sp. to humans was facultative.

Although magnetic resonance imaging without linear hardening of CT is recognized as a method of obtaining high contrast of tissue and excellent resolution image in brain disease and head and neck examination, magnetic susceptibility artifact is generated in case of metal implants in the oral cavity, which is an obstacle to image diagnosis. Therefore, an effort was made in this thesis to find a method to reduce artifacts caused by dental implants and prosthesis in MRI. Implant-induced artifacts in magnetic resonance imaging showed that the signal size increased with shorter TE in GE technique and was inconsistent with water temperature change. In SE technique as well, the signal size of water was generally higher than that of air, but the signal to noise ratio (SNR) was not different by air and temperature. In EPI technique, images with fewer artifacts were obtained quantitatively and qualitatively when there was more water than air, and the signal to noise ratio was measured the highest, especially at water temperatures of 20° and 30°. In conclusion, when examining using the EPI technique rather than the SE or the GE technique, obtaining brain diffusion using a 20° and 30° water bag reduces the magnetic susceptibility artifacts caused by implants and prosthesis, suggesting that it may provide images with high diagnostic value.

Spontaneous pneumothorax is rarely occurred as an initial sign of primary lung cancer. As a lot of these cases have already advanced, even then surgical resection is performed, the prognosis is often undesirable, We happened to find a ruptured cavity on a 65-year-old male patient who had suffered from pulmonary tuberculosis in the past, while performing VATS bullectomy for simple spontaneous pneumothorax, Then, as a result of frozen biopsy, it was diagnosed as squamous cell cancer Because the tumor was infiltrated from the upper lobe into the lower lobe passing by fissure, we should remove by pneumonectomy and the pathologic stage was found stage I(T2N0M0). When we made an follow-up observation for one year and a half, there was neither relapse nor complication. When there appears spontaneous pneumothorax to the high risk group for lung cancer who were smokers over forty-year old, with chronic bronchitis or pulmonary emphysema, it needs to have a closer observation on a base lung disease such as lung cancer through chest CT, and it is also necessary to make more active approach by performing the surgical operation through a thoracoscopy when there is a continued air release.

A clinical study of 36 cases of pulmonary tuberculosis that had had a surgical resection during the period of 13 years from January 1979 to December 1992 was performed in the Department of Thoracic and Cardiovascular Surgery, Chonbuk National University Hospital The ratio between male and female was 3.5 1 and the age of peak incidence was in the 2nd and 3rd decades. The common prodromal symptoms were chest pain (38.9 %) and hemoptysis or blood tinged sputum (36.1 %). Preoperative diagnostic examination of sputum positivity for AFB stain despite antituberculosis chemotherapy was noticed in 22.8 oyo . Surgical indications were destroyed lobe or segment with or without cavity (58.3 oyo), mass unable to differentiate from lung cancer (16.7 %), total destroyed lung (13.9 %), bronchostenosis with atelectasis and distal bronchiectasis (11.1 %). Types of resection were pneumonectomy in 16.7%, lobec omy and segmentectomy 2.7%, lobectomy 50 %, segmentectomy 27.8%, and wedge resection 2.7%. Postoperatively, pulmonary function Improved compared to the preoperative examination, although these changes were not statistically significant. One patient died of ulcerative colitis due to drug hypersensitivity, and the postoperative complications were remnant dead space in 11.1 %, spreading of tuberculosis in 5.5%, and empyema with BPF in 5.5%.

Background: Pleural drainage following video-assisted thoracic surgery has traditionally been achieved with largebore, semi-rigid chest tubes. Recent trends in thoracic surgery have been toward less invasive approaches for a variety of diseases. The purpose of this study was to evaluate the safety and efficacy of drainage by means of small, soft, and flexible 14Fr Blake drains. Material and Method: Between December 2007 and March 2008, 14Fr silastic Blake drains were used for drainage of the pleural cavity in 37 patients who underwent a variety of video-assisted thoracic surgical procedures at our institution. Result: The average postoperative length of hospital stay was 3.26 days (range, 2~12 days), Blake drains were left in the pleural space for an average of 3.15 days (range, 1~7 days), and the average amount of drainage was 43.8 ml/day. The maximal amount of blood removed daily by a Brake drain was as much as 290 mL. There were no drain-related complications. Blake drains seemed to cause less pain while in place, and particularly at the time of removal. Conclusion: The use of a Blake drain following minor thoracic surgery appeared to be safe and effective in drainage of fluid or air in the pleural space, and were associated with minimal discomfort.

In this study, 2-D seepage analysis is conducted for the evaluation of Box-Culvert installation, Cut-off Wall Length, permeability reduction of soil under the Box-Culvert effects on Levee Box-Culvert safety. The result of analysis it is obtained that the safety of seepage and slope stability of levee is declined by the installation of Box-Culver. And also obtained that the piping from poor compaction and cavity around Box-Culvert Is Prevented by the Cut-off wall installation below breast wall and levee toe, so it is recommended that the Cut-off Wall below breast wall and levee toe must be installed. And the Cut-off Wall installed below levee center is considered when the safety of piping is declined for the whole levee section. On the other hand, for the realistic analysis it is recommended that the 3-D seepage analysis is more suitable for the safety evaluation of Box-Culvert installed levee when it is considered that the saturated field is dispersed to the ground.

It is very important that analysis of textures in rock, the moving of hydrothermal solution along the structures, epithermal vein textures, mineralization and composition minerals to confirm the hydrothermal ore deposits and ore genesis. The purpose of this study is to confirm the gold mineralization and ore genesis through the moving of hydrothermal solution along the structure lines and epithermal vein textures by using Color-corescanner techniques. The three drilling hole cores of Sunshin Gold Mine in Haenam area in Jeonnam Province were into a digital image data. Digital image data of gold bearing epithermal vein textures were analyzed detaily by Color-corescanner. There are several epithermal vein textures, namely Comb texture, Cavity texture, Bladed texture, Zonal texture, Brecciated texture and Combined texture. Gold mineralization is dominated in vein type textures, but high grade gold are enbedded in brecciated texture. Ore genesis is epithermal gold deposit. This Color-corescanner techniques can cover the missing part of the examine with the naked eye, and can examine closely the situation of ore deposit development and genesis by detail checking the textures in rock, mineralization and so on.

Objectives : The purpose of this study was to correlation between the index of dental caries in primary teeth and the habits of diet and snack which are expected to influence on the index. The subjects of this study were 165 parents of the children who visited a pediatric dental hospital located in Gyeong-gi do from Jun. 15th to Sep. 26th, 2009, and the self-report questionnaire survey was performed. Methods : A questionnaire used in a previous study was revised and completed for this study and it consisted of 15 items on general characteristic, nine items on dietary habit, and five items on snack intake habit. The collected data was analyzed using SPSS program and findings are as follows Results : 1. The index of dental caries in primary teeth by ages was that children of four years old has 4~5 with 27.5%, children of five years old has 2~3 and 4~5 with 33.3% and children of six years old has 1 and 8~9 with 25.6%, showing a statistically significant(${\chi}^2$=37.72, p<.01). 2. The frequency of brushing teeth was found to have statistically significant negative correlation with the number of primary teeth with dental caries (${\chi}^2$=61.20, p<.001). 3. The frequency of taking snack was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=51.42, p<.001). 4. The desirability of dietary habit was found to have statistically significant negative correlation with the number of primary teeth with dental caries (${\chi}^2$=36.51, p<.001). 5. The frequency of taking biscuit was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=67.74, p<.001). 6. The frequency of taking bread was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=29.63, p<.01). 7. The frequency of taking caramel and candy was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=38.85, p<.001). 8. The frequency of taking soft drinks was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=52.92, p<.001). 9. The frequency of taking ice-creams was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=75.07, p<.001). Conclusions : Those findings show that the children with undesirable dietary habit and higher frequency of taking snack have higher index of dental caries in primary teeth, therefore, it is considered that the regular brushing teeth and establishment of desirable dietary habit are very important for keeping health oral cavity. It is recommended that the continuous concern and repeated learning are needed in house and group of rearing infants so that the children take foods of fruits which have function of self-purification than the food of carbohydrates which has high adhesion and level of sweetness.
