However, Endoscopic retrograde cholangiopancreatography (ERCP) is still helpful procedure for the diagonosis of the pancreatobiliary disease and treatment through endoscopic sphinterectomy (EST) is relatively safe, these have possiblity of complications such as hemorrhage, infection, panceatitis, and perforation. ERCP related perforation was rarely reported in 0.3 to 1.1% of previous study, but most serious complication. A report of Pneumomediastinum, Tension Pneumothorax complicating perforation after ERCP and EST is very uncommon. In our hospital, we experienced case of pneumomediastinum, subcutaneous emphysema, and tension pneumothorax after ERCP and EST, and the patient (a 58 years old female with suspicious common bile duct stone) was treated successfully with conservative treatment.

Abstract - The high-speed fiber-optic networks rapidly has come into wide use and in the process of use because the last developing acceleration of the telecommunication technology but, they must need the high foundation cost therefore a heavily populated district was suitable. On the order hand a lightly populated district incongruent. Powerline communications merit attention because the lower foundation cost for using of the existing powerlines. The coupling Circuits are High pass filter and blocking high-voltage. The coupling circuits consist of capacitance so called the coupling capacitor. In the thesis the coupling capacitor try design, simulation and fabrication. After studying a characteristic of frequency in the temperature that the fabrication capacitor study conformability of the coupling capacitors.

In GaAs devices, the development of a finer insulator instead of SiO₂to be used the insulator of Si has been made good progress. That, however, is not to be enough. We studied the development of the finer insulator in GaAs devices. The AIN has the characteristics of thermal stability over 2400℃ and resistivity over 10 13 Ω, and superior insulator characteristic to have rate of thermal expansion(a=4.2x10 -6, b=5.3x10 -6/K) similar with SiO₂and GaAs. An AIN has been evaluated good applied insulator for above characteristics in chemical compound. Then, the purpose of this paper is a development of MIS devices using AIN as an insulator, and is to investigate a electrical characteristic changing by H₂addition to AIN. The ratio of H₂addition was established by 5%. The pressure was maintained by 5 mTorr and the DC power was supplied by 150W during the experiment. The H₂addition to AIN may have an effect on diminishing impurities on surface and improves the properties as an insulator to a MIS structures.

Pseudomembranous colitis (PMC) is a disease caused by Clostridium difficile proliferation. The causative drugs are clindamycin, third-generation cephalosporins, flouroquinolone and so on. Rifampicin has been reported as a cause of PMC in the 1980s, and the frequency of PMC is increasing because rifampicin is a first line drug for anti-tuberculosis therapy. Two patients were recently admitted to our hospital due to watery diarrhea for 1 month and they were diagnosed with PMC by sigmoidoscopy. Their onset age were 74, 72 years old and latent period of symptoms were 60, 129 days, respectively. In one case, the patient displayed coexisting hypertension and diabetes. The clinical symptoms improved after discontinuing the rifampicin and then administering oral metronidazole. We report here on two cases presumed to be rifampicin-induced PMC.

A clinical case review of 220 patients of replantation which performed at the Department of Plastic and Reconstructive Surgery, National Medical Center from April 1981 to October 1984 is presented. The total replants were 377 with overall success rate of 85 percent. This result is comparable to Tamai , Kleinert, O'Brien, and Urbaniak. Particularly it deserves attention that the success rate of salvage procedure which performed at zone Ⅱ and Ⅲ was relatively high with 62% success rate. The clinical results are as follows: 1. The average age is 24 years and male to female ratio is 6:1 2. The causes of injury are detailed as follows: presser,cutter,electric saw. 3. The average ischemic time is 13 hours. 4. The survival rate is 85 percent. 5. The survival rate is more related to type of injury than ischemic time.

In this thesis, we studied the design and fabrication of microwave multilayer chip filter using by coupled stripline resonator. The microwave multilayer chip filter operating at 700[MHz] is fabricated and designed. The size of microwave multilayer chip filter is 4.5×4.4×1.8[mm]. Insertion loss and center frequency of the fabricated chip filter are 2.58[dB] and 692.5[MHz] respectively. The center frequency was lower 7.5[MHz] than design result, but other characteristics of chip filter were similar to the results of simulation.

In this paper, designed and fabricated the 1.9GHz band isolator for wire-less communication base-stations. It was investigated that characteristics of insertion loss and return loss. The characteristic results of dual structure design showed values that insertion loss was about -40dB and return loss was about -23dB at 1.93~1.99GHz.

The purpose of this study was to investigate the change of related factors in cardiovascular function variables after long duration regular exercise programs. The subjects of this study were 40 older man and women residing Seoul-Seniors-Tower. All of subjects divided to four groups, exercise group 20(man = 10, women = 10) was participating in an exercise program for 3 years, and the other group or non-exercise group 20(man = 10, women = 10) was not in that program. In the results, Changes of cardiovascular function were significantly improved in peak oxygen uptake, ventilation, rest blood pressure of cardiovascular function variables in male or female exercise groups after 3 years' exercise program. Also, we have been known to the facts that although the cardiopulmonary variables of men are superior to those of women, if being exercised for a long time, the women's cardiopulmonary variables(e.g. Endurance time, HRrest, SBPrest, SBPmax, DBPrest, RPPrest, and RPPmax) would not different from those of the men especially in old ages. As a conclusion, we could know that not only the regular exercise might increase or change almost the cardiovascular function variables except for V ˙O2max, Ventilation, and HRmax of elderly people, but also the sex's differences were vanished in endurance time, HRrest, SBPrest, SBPmax, DBPrest, RPPrest and RPPmax between males and females. Therefore, we might tell that exercise programs could provide an excellent parameters for enforcing or keeping the cardiovascular functions of elderly people.

Background : An important issue in health care today is in trying to center service around the hospitalized patient. There is a "kindness Movement" developing now. Where in the focus of Health Care is being changed from simply treating the basic physical needs of the patient with sophisticated technology. to keeping emotional well being healthy with more humane and attentive treatment. In our attempt to reach the goal of a completely satisfied patient, we undertook a study of the common complaints of patients, and the subsequent nature of the interventions. Method : The study was carried out in two stages, first the patients made known their complaints by filling out questionnaires, then we collected data on the attempts to alleviate the complaints. The questionnaire provided 19 different complaints, which were then analysed for such variables as content, source of complaint, persons treating the complaint, and length of time and method used to solve the complaint. Result : 1. The Chief complaints made by patients(99.1%) were of physical discomfort, such as pain, nausea, vomiting, indigestion, diarrhea and constipation. 2. The complaints were vioced primarily by either a member of the patient's family, or by the patients themselves(78.4%). 3. The complaints were intervened by nurses alone(53.5%), physicians alone(25.5%), or by nurses and physicians together(19.25%). 4. The method by which the complaints were resolved included the utilization of prescriptions(55.7%), turther explanation and education (25.5%) and notification after treatment(13.2%). 5. Most complaints were voiced during the dayshift (42.6%, 7:00~15:00), followed by the evening shift(36.0%, 15:00~22:00) ;and then the nightshift(21.3%, 22:00~07:00). 6. The time required for successful resolution of the patient's problems varied from 10~88.9mi, according to the nature of the complaint. Conclusion : Hopefully by knowing beforehand the nature of both complaint and intervention, we can anticiapte problems and shorten reaction time, in order to provide for a more satisfied patient.
