The expectoration of blood is always a fearful experience for the patient and a matter of grave concern to the attending physician, because it may be the warning sign of serious diseases. When such bleeding occurs, the possibility of its being due to pulmonary tuberculosis, bronchiectasis or carcinoma of the lung is promptly suggested. Nowadays, with the advance of modern diagnostic studies, differential diagnosis has become possible for the hemoptysis patients to have appropriate treatment. This evaluation is based on the review of 75 cases of patients whom we performed emergency open thoracotomies for 6 years from March 1992 to February 1997 in the Department of Thoracic and Cardiovascular Surgery, Seoul Adventist Hospital. The mean age of the patients was 36.6 years old with a range from 19 to 68, and most prevalent age group was thirties. The most common underlying lung disease causin hemoptysis was tuberculosis(44%). Most accurate diagnostic study was bronchoscopy during hemoptysis(95 Vo) and right middle & lower lobe(17.3%) was the most common site of lesion. Lobectomy(50%) was the most frequent operative method and recurrent hemoptysis(31.6%) was the most common postoperative complication. But most of the patients(82.6%) were completely recovered by surgical treatment. Now we concluded that the proper management of hemoptysis was completed by surgical approach with definite diagnosis and supportive medication.
Packaging takes an extremely important element of optical module cost due primarily to the added complication of alignment between semiconductor devices and optical fiber, and many efforts have been devoted on reducing the cost by eliminating the complicated optical alignment procedures in passive manner. In this study, we fabricated silicon optical benches on which the optical alignments are accomplished passively. To improve the positioning accuracy of a flip-chip bonded LD, we adopted fiducial marks and solder dams which are self-aligned with V-groove etch patterns, and a stand-off to control the height and to improve the heat dissipation of LD. Optical sub-assemblies exhibited an average efficiency of -11.75$\pm$1.75 dB(1$\sigma$) from the LD-to-single mode fiber coupling and an average sensitivity of -35.0$\pm$1.5 dBm from the fiber and photodetector coupling.
Oronasal fistula are a well-known complication of surgical treatment of cleft palate, occurring most frequently in the alveolus and hard palate. Previous reports have demonstrated that oronasal fistulas, particularly if greater than l cm in diameter, had an adverse effect on speech. The aim of this study was to demonstrate the relationship between the size of the fistula and the influence on velopharyngeal function. The site and size of the fistula were indicated on graph paper with calipers and measured in $mm^2$. Speech assessment was carried out using a Nasometer, VPI articulation differential test, spectrography. Patient whose fistulas affected their speech had significantly larger fistulas than those whose fistulas did not. The study shows that the larger the fistula, the greater the risk of hypernasality and nasal emission, but even small fistulas can cause speech problems. If obstruction of the nasal passage is eliminated in a patient with a previously asymptomatic fistula, it may result in a fistula becoming symptomatic, resulting in hypernasality and nasal emission. In conclusion, even small fistulas can influence speech production and should be considered before any treatment is planned. The study lends support to early closure of oronasal fistulas, particularly before pharyngeal flap surgery is contemplated.
A ten-year-old female mongrel dog was presented to Veterinary Medical Center, Chungbuk National University with the signs of anorexia, weakness, and hemoglobinuria. Patient had been diagnosed as dirofilariasis based on heartworm antigen test and treated with adulticide (melarsomine) at local hospital one day before admission. On laboratory examinations, there were hypochromic and microcytic regenerative anemia, thrombocytopenia, moderate neutrophilia, and increase ALT, AST, and ALP. Radiographic exam showed main pulmonary artery bulging, pulmonary infiltration and hypervascularity, reduced abdominal serosal detail and mild hepatomegaly. Abdominal ultrasonographic exam showed mild peritoneal effusion and large hyperechoic thrombi at trifurcation of the porta hepatica and the splenic vein. In addition, intraluminal low density area and intravascular filling defect were confirmed on contrast enhanced CT scanning at the same anatomic locations. Patient was treated with anticoagulant and thrombolytic therapy. On day 42 after treatment, complete resolution of thrombi was confirmed via ultrasonography and improvement of clinical signs was observed.
This study is trying to analyse the correlation between the crime behavior and the social alteration or development. Capitalism reposes on economic competition, and the impact of capitalism is according to crime behavior. Then the type of crime and the diversity of crime are transformed by the social environment and the social development. So this study is divide into 3 parts. The first is the correlation between industrialized and crime. It means that the industrialized is accompanied with the urbanized and arouse a material desire, these social phenomenon are a high correlation with increase of violent behavior and the crime. The second party is explain and analyse the correlation between the information and the crime. The information causes other type crime by contrast with the industrialized age and society. If the industrialized has caused the violent behavior and the crime, the information is too clever by half and break out the crime in the companionship of innumerable unspecifiness. So, the crime of the information age is a very wide scope and casualties, especially has a concealment of crime. And the third party describe in conclusion the social alteration and the extension of crime. Social alteration or social development is according to economic development. Competitive economic development include many complication and friction in a society, these factors are expressed in various crime. In the result the occurrence and the type of crime is a high correlation between the social alteration or development.
With the recent enlargement and complication of buildings, damage caused by the incidents of fires breaking out are escalating. Consequently, the use of sprinkler facilities is increasing among water-based fire extinguishing systems. Piping materials used in fire prevention systems include carbon steel (for general or pressure pipeline), CPVC, copper, and stainless-steel. Among these, the steel and CPVC pipes, which are commonly employed in fire prevention, were considered for testing the reliability of the water-based systems. This analysis was performed using the PIPENET software to perform hydraulic calculations in order to examine the flow and pressure at the terminal head when the corrosion coefficient was applied; this coefficient was applied considering the aging of pipes. Assuming a uniform pipe diameter in the steel pipes, the rated flow in the pump installed on the first floor of the basement was reduced by over 10% after 20 years had passed (C value of 90); moreover, the reduction in pressure and flow at its terminal head exceeded 30% and 16.5%, respectively. The results indicate that it is difficult to ensure the reliability of these fire prevention facilities. Furthermore, according to our estimation, considering 30 years had passed (C value of 80), the rated flow of the pump was reduced by over 15%, and the corresponding reduction in pressure and flow at its terminal head exceeded 42% and 24%, respectively.
Clinical Observation was made on 37 cases of Endotracheal intubation patients in the ICU of Oriental Medical Hosptal of Tae- Jon University from January in 1992 to June in 1995. 1. There were many cases of Endotracheal intubation in ischemic attack hemorragic in order. 2. Cerebral embolism mostly occured in the MCA territory and cerebral thrombosis, ICH, in the pons, generally. 3. On admission the consciousness of the most patients was 3 to 7 point by GCS. 4. The ordinary preceeding disease was hypertension. 5. Most patients were discharged from ICU after 2 days. 5. Most patients were discharged from ICU after 2 days. 6. Endotracheal intubation was done most frequently from 1 p.m. to 3 p.m. and intubated time was less than 2 hours. 7. Endotracheal intubation was done in case of heart arrest than dyspnea cases. 8. The main complication of patients of C.V.A. in ICU were urinary tract infection, pneumonia in order. 9. There were no side effects after and by Endotracheal intubation.
Purpose: To evaluate the results and prognosis of operative repair to acute rupture of achilles tend on associated sports injury. Materials and Methods: 21 cases were surgically treated and average follow-up period was 1 year and eight months. The forth decade was most common with $55\%$ and soccer was most common in sports with 5 cases. End-to-end suture of ruptured achilles tendon was performed, and paratendinous structure was wrapped sufficiently. Postoperatively. ankle was plantarflexed for 6 weeks with longleg cast. And then 2 weeks interval, short leg cast with equinous position was conversed to functional position. About 10 weeks after operation, ankle was recovered to right angle. Hooker scale was used to evaluate the results. Results: Compared to normal side, heel-floor distance of ruptures side was decreased 0.7 cm in average, and 0.8 cm was deceased after 20 times weight loaded dorsiflexion. Mid-calf circumference was deceased 0.3 cm, and active dorsiflexion and plantar flexion of ankle was decreased each 3 and 5degree. 16 cases showed ‘excellent’result and 5 cases showed ‘satisfactory’. There was no complication, such as re-rupture or infection at operation site. Conclusion: After end-to-end operative repair to achilles tendon, sufficient wrapping of paratendinous structure is efficient for healing and prevention of postoperative adhesion. And serial dorsiflex-ion cast change is considered to be a successful treatment for preventing residual equinus deformity.
Purpose: The purpose of this study was to assess the 2-year follow-up results of patients with a trimalleolar fracture, who had undergone an anterior incision cannulated screw fixation of the posterior malleolar fragment, which had more than 25% of articular involvement or had no cortical continuity with the distal tibia. Materials and Methods: Among 28 patients with a trimalleolar fracture who had undergone fixation of the posterior malleolar fragment between February 2005 and February 2010, 14 patients, who underwent an anterior incision cannulated screw fixation of posterior malleolar fragment and were followed-up for more than 2 years, were selected. The postoperative clinical and radiological findings immediately and at the 1- and 2-year follow-up were compared. The clinical findings were evaluated as American Orthopaedic Foot and Ankle Society (AOFAS) score. The radiological assessment was evaluated as the maintenance of reduction, period to bone union, and the presence of nonunion, malunion, and complications. Results: The clinical outcome by mean AOFAS score revealed 83.0 points in the group with preoperative displacement below 2 mm and 80.7 points in the group with preoperative displacement above 2 mm postoperatively. The mean AOFAS score was 91.7 and 93.1 points in the group with preoperative displacement below 2 mm on 1- and 2-year follow-up, respectively, and 89.8 and 91.7 points in group with the preoperative displacement above 2 mm on 1- and 2-year follow-up, respectively. After a 2-year follow-up among 14 cases selected for this study, 13 cases showed an excellent reduction state and only 1 case (7.1%) showed a displacement of more than 2 mm. No complication were encountered in the group with preoperative displacement below 2 mm. On the other hand, among 8 patients in the group with preoperative displacement above 2 mm, there were 3 with limitations of the range of motion of the ankle joint (37.5%) and 1 post-traumatic arthritis (12.5%) at the 2-year follow-up. Conclusion: Anterior incision cannulated screw fixation of the posterior malleolar fragment could be a valuable method for the treatment of trimalleolar fractures that provides satisfactory results.
Statement of problem. The performance and maintenance of implant-supported prostheses are primarily dependent upon load transmission both at the bone-to-implant interface and within the implant-abutment-prosthesis complex. The design of the interface between components has been shown to have a profound influence on the stability of screw joints. Purpose. The Purpose of this study was to compare the strength and the fatigue resistance of 1-piece and 2-piece abutment connected to oral implant, utilizing an internal conical interface. Material and methods. Twenty $Implatium^{(R)}$ tapered implants were embedded to the top of the fixture in acrylic resin blocks. Ten $Combi^{(R)}$(1-piece) and $Dual^{(R)}$(2-piece) abutments of the same dimension were assembled to the implant, respectively. The assembled units were mounted in a testing machine. A load was applied perpendicular to the long axis of the assemblies and the loading points was at the distance of 7mm from the block surface. Half of 1-piece and 2-piece abutment-implant units were tested for the evaluation of the bending strength, and the others were cyclically loaded for the evaluation of the fatigue resistance until plastic deformation occurred. Nonparametric statistical analysis was performed for the results. Results. Mean plastic and maximum bending moment were $1,900{\pm}18Nmm,\;3,609{\pm}106Nmm$ for the 1-piece abutment, and $1,250{\pm}31Nmm,\;2,688{\pm}166Nmm$ for the 2-piece abutment, respectively. Mean cycles and standard deviation when implant-abutment joint showed a first plastic deformation were $238,610{\pm}44,891$. cycles for the 1-piece abutment and $9,476{\pm}3,541$ cycles for the 2-piece abutment. A 1-piece abutment showed significantly higher value than a 2-piece abutment in the first plastic bending moment (p<.05), maximum bending moment (p<.05) and fatigue strength (p<.05). Conclusion. Both 1-piece and 2-piece conical abutment had high strength and fatigue resistance and this suggests long-term durability without mechanical complication. However, the 1-piece conical abutment was more stable than the 2-piece conical abutment in the strength and the fatigue resistance.
