Hepatopulmonary syndrome (HPS) is a serious complication of end-stage liver disease, which is characterized by hypoxia, intrapulmonary vascular dilatation, and liver cirrhosis. Liver transplantation (LT) is the only curative treatment modality for patients with HPS. However, morbidity and mortality after LT, especially in cases of severe HPS, remain high. This case report describes a patient with typical findings of an extracardiac pulmonary arteriovenous shunt on contrast-enhanced transesophageal echocardiography (TEE), and clubbing fingers, who had complete correction of HPS by deceased donor LT. The patient was a 16-year-old female who was born with biliary atresia and underwent porto-enterostomy on the 55th day after birth. She had been suffered from progressive liver failure with dyspnea, clubbing fingers, and cyanosis. Preoperative arterial blood gas analysis revealed severe hypoxia (arterial O2 tension of 54.5 mmHg and O2 saturation of 84.2%). Contrast-enhanced TEE revealed an extracardiac right-to-left shunt, which suggested an intrapulmonary arteriovenous shunt. The patient recovered successfully after LT, not only with respect to physical parameters but also for pychosocial activity, including school performance, during the 30-month follow-up period.

The purpose of this study was to evaluate the effects in respire-circulatory function and cadio-pulmonary endurance capacity. Twelve females(trained 6, untrained 6) participated in dancesport program that is 90min/day, 2day/week for 20weeks. The results were obtained as follow : 1. No significant difference was found in heart rate, ventilation and respiration rate among pretest, after 10 weeks and 20 weeks of dance program and between trained and untrained group. 2. Significant differenced was found in VCO₂between pretest and 20Weeks later in untrained group. 3. There was significantly increased VO₂max in 20 weeks dance program later compared with pretest and significant difference between groups. 4. There was no significant difference in ventilatory threshold and exercise time was not significant difference among trials and between groups. Conclusively, respiro-circulatory function and cardio-pulmonary endurance capacity were not changed at submaximal stage of excise test but those were significantly increased at maximal of exercise test during 20 weeks. Therefore, it is suggested that long term dancesport exercise program is expected more effective on the repiro-circulation function and cardio-pulmonary endurance capacity.

제1대구치는 저작과 혼합치열기 이후의 수직적 교합관계형성에 핵심적인 역할을 하고 악골의 성장발육에 관여한다. 제1대구치의 매복은 하안면 고경의 감소, 낭의 형성, 치관 주위염, 인접치의 치근 흡수, 부정 교합 등의 문제점을 야기할 수 있다. 치료방법으로는 주기적 관찰, 외과적 노출술, 교정적 견인, 외과적 재위치술, 발치 등이 있으며 이중 외과적 노출술이 가장 기본이 되는 술식이다. 외과적 노출술시에는 맹출로의 개방성을 유지하는 것이 중요하며 개방성을 유지시키기 위한 방법으로는 레진관의 접착, 산화 아연 유지놀 시멘트, 치주포대 등을 노출된 부위에 충전시키는 방법 등이 있다. 본 증례에서는 매복된 하악 제1대구치에서 장애물의 제거와 외과적 노출술을 시행한 결과 자발적인 맹출을 관찰할 수 있었다. 또한 surgical pack과 투명상유지장치를 사용하여 간편하고 효과적으로 맹출로의 개방성을 유지할 수 있었다.

Airline industry is going to change more rapidly according to innovation of high technical circumstance. Especially, increasing of internet user add to the importance of that. Today, people like to get the any information and take action from the internet web site. I studied internet web site of airline corporation with internet marketing strategy. It is adapted with 4P's of internet marketing and give new internet marketing strategy for the airline corporation. The samples are 21 big airline corporations web site which are divided by 4 alliance program. These are Star alliance, One world, Wings, Atlantic excellence. Ater a result, I could suggest several internet marketing strategy. Internet is more importance things in the next century. A number of people want to get any information and contact directly by using internet. In case of airline corporation, the product sales pattern will be change from the pattern of airline corporation→agent(travel agency)→customer to the pattern of airline corporation→customer. Of course, although there are somethings to solve the problem which are contact circumstance, contact speed, payment security device and limitation of number of internet user, but it will be overcome through in a few years. Thus, they should prepare about that situation and more make new system and manage to satisfy their customer. Now, we need more specific study on this subject in the next time.

목 적 : 사회기술훈련, 환자교육, 가족교육, 집단치료, 예술치료, 작업치료와 같은 포괄적인 정신재활 치료를 약물치료와 병행할 경우 약물치료만 시행할 때에 비해 정신분열병 환자의 재발율, 입원횟수, 입원일수, 직접 치료경비 등에 어떤 효과가 있는 지를 알아보기 위함이다. 연구방법 : 1993년 9월부터 1995년 2월까지 양산 신경정신병원의 폐쇄병동에서 퇴원한 20∼35세 사이의 정신분열병 환자 173명을 대상으로 46명에게는 6개월동안 정신재활 치료를 시행하였고 127명에게는 통상적인 외래치료만 시행한 후 연구시작 시점을 포함하여 2년동안 양군에 속한 환자들을 대상으로 재발율, 입원횟수, 입원일수, 직접 치료경비 등을 1년 단위로 추적 조사하였으며, 연구시작 시점을 기준으로 전과 후의 매년 평균 입원횟수, 입원일수, 직접 치료경비도 서로 비교하였다. 결 과 : 정신재활 치료를 약물치료와 병행할 경우 약물치료만 시행할 때에 비해 재발율, 입원횟수, 입원일수, 직접 치료비용이 현저히 감소되었다. 그리고 정신재활 치료를 받은 군에서는 치료 전에 비해 치료 후에 재발율, 입원횟수, 입원일수, 직접 치료비용이 유의하게 감소하였지만 통상적인 외래치료만 받은 군에서는 치료 전과 후간에 유의한 변화를 보이지 않았다. 결 론 : 정신분열병 환자들에게 정신재활 치료를 약물치료와 병행할 경우 약물치료만 시행할 때에 비해 환자의 임상적 경과를 호전시킬 뿐 아니라 가족의 경제적 부담도 줄일 수 있다. Objective : We evaluated the clinical efficacy of a comprehensive psychiatric rehabilitation of schizophrenia, including family psychoeducation, patient education, social skills training, group psychotherapy, art therapy, and occupational therapy. Method : From September 1993 to February 1995, 173 chronic schizophrenics who met DSM-IV criteria and were discharged from a locked ward were assigned into the psychiatric rehabilitation service group(psychiatric rehabilitation group, n=46) or the customary out-patient service group(out-patient group, n=127) prospectively, but not randomly. Assignment was based on preferences of patients and their relatives, Each subject included in the psychiatric rehabilitation group received twice weekly patient education, social skills training, family psychoeducation, group psychotherapy, art therapy, occupational therapy and maintenance chemotherapy during a 6-month period. Those in the out-patient group received individual supportive psychotherapy and maintenance chemotherapy according to their clinical needs for 10-20 minutes once per week. After entry into the study, all subjects were assessed for the number of readmission, days of hospitalization, and the direct treatment costs through the first and second year of follow-ups. These outcome variables were also compared pre-and post-2 years at the time point of entry into the study. Aftercare chemotherapy on a weekly to monthly basis continued for the remainder of the two year follow-up period. Results : With regard to the mean number of hospital admissions per year, the mean days of hospitalization per year, and the direct treatment costs per year, the psychiatric rehabilitation group had significantly decreased all clinical outcomes 2 years after compared with before receiving psychiatric rehabilitation. But there were no significant differences in the all clinical outcomes between before and after study intake in the out-patient group. For the number of relapse regardless of drug compliance, 4 patients(9%) during first year and 14 patients(30%) during second year were relapsed in the 46 subjects of the psychiatric rehabilitation group. In contrast, 75 patients(59%) during first year and 90 patients (71%) during second year relapsed in the out-patient group. When considering the effect of drug noncompliance to relapse, 4(9%) and 14 patients(30%) were relapsed while on medication respectively during the first and second year in the 46 of the psychiatric rehabilitation group, vs. 27(34%) of 79 patients on medication during the first year and 31(46%) of 68 patients on medication during the second year were relapsed in the out-patient group. Conclusions : These results indicate that the comprehensive psychiatric rehabilitation can be useful therapeutic intervention both to improve the clinical outcomes of schizophrenic patients and to reduce the economical burden of their relatives.

In the design process of a press product, the reverse engineering is a necessary process. Therefore, the method of measurement must be constructed for a blank shape. In order to measure a blank shape, the vision system with non-distortion ren was constructed, and the image processing, the shape recognition and the element extraction module was made with the Visual C++ language. For the shape recognition, the distance-angle function with a shape characteristics ware used and, for the shape of element extraction, the slop function with a element characteristics was used. In this study, the shape of the rectangular gage block and circular product with a simple shape was recognized and elements in the polygon were extracted by using this system.
