Hydrogen isotopes accountancy and storage are important functions in a nuclear fusion fuel cycle. The hydrogen isotopes are safely stored in metal hydride beds. The tritium inventory of the bed is determined from the decay heat of tritium. The decay heat is measured by circulating helium through the metal hydride bed and measuring the resultant temperature increase of the helium flow. We are reporting our preliminary experimental results on the hydrogen isotopes accountancy and storage performance in a metal hydride bed.

Transmesenteric hernia, a type of internal hernias, is a rare cause of intestinal obstruction. This intraperitoneal hernia has no sac and is formed by protrusion of a loop of bowel through an aperture in the mesentery. Incarceration leads to intestinal obstruction and subsequently, strangulation and gangrene of varing lengths of intestine. This is a case report of 4-year-old girl with transmesenteric herniation of the terminal ileum through a defect in its own mesentery. Strangulation of the affected bowel necessitates resection and primary anastomosis with repair of mesenteric defect. The postoperative course was uneventful. Acute intestinal obstruction in the absence of an external hernia and with no history of a previous surgical procedure suggests the possibility of an internal hernia, especially if the patient has a history of chronic intermittent abdominal distress.

외상으로 인한 횡격막 파열과 그로 인한 신장 이탈은 드문 현상이며, 더욱이 신장 이탈시 신장 다리(renal pedicle)가 완전히 찢어지는 현상은 매우 드물게 발생하며 응급 수술을 시행하지 않으면 생명이 위험할 수 있다. 이에 저자들은 외상성 횡격막 파열과 함께 흉강 내 혈관과 요관이 완전히 찢어진 상태로 신장이 탈출한 1예를 경험하였기에 간단한 문헌 고찰과 증례를 보고하는 바이다.

Fourteen cases of diaphragmatic hernias surgically treated at the Dept. of Thoracic ＆ Cardiovascular Surgery in Kosin Medical Center from Jan. 1979 to Feb. 1991, were reviewed in this study. This report includ 9 cases of traumatic diaphragmatic hernia, 5 cases of congenital diaphragmatic hernia. Among the traumatic hernias, 5 cases were blunt trauma and 4 cases were penetrating trauma. Five cases of congenital diaphragmatic hernias were presented, including 2 cases of esophageal hiatal hernia, 2 cases of Bochdalek's hernia and a case of Morgagni's hernia. Operation was performed in all patients. Results of all treated cases were excellent.

The occurrence of traumatic hernia is rare. However, traumatic lumbar hernias are the most frequently occurring traumatic hernias. Superior lumbar hernias occur more frequently than inferior lumbar hernias, but for anatomical reasons, among traumatic lumbar hernias, inferior lumbar hernias occur more frequently than superior lumbar hernias. Repair of a lumbar hernia is very difficult. Mesh fixation to the bony part and general weakness of surrounding tissue make repair of a lumbar hernia tricky. A traumatic lumbar hernia was repaired using transfascial fixation around the defect to secure the mesh. This technique is another choice for a lumbar hernia technique.

Foramen of Morgagni hernia is the least common type of all congenital diaphragmatic hernias. These foraminal hernias result from a congenital defect in the development or attachment of the diaphragm to the sternum and costal arch. They occur most commonly on the right side, possibly because of pericardial reinforcement of the left. In our case, occurred on the right side and the contents of the hernial sac were omental fat and a part of transverse colon. We performed transthoracic approach for reduction and repair of foraminal hernia with ligation and interrupted mattress sutures of the margin of the defected diaphragm to the posterior part of the sternum and costal cartilage. The postoperative course was uneventful except posttraumatic delirium and discharged at 21st postoperative day.

Esophageal hiatal hernia is common disorder in western sociey, and mainly affects mid-aged women, There are two types of hiatal gernia; common and more benign type is sliding [type I], and more severe type is paraesophageal [type II], and Skinner subdivided type II as true II, IIA, III, and paraesophageal group, As Skinner`s nomination, this case could be belong to IIA, which imply the state that natural hiatus is occupied with gastric antrum or duodenum instead of normal esophago-gastric junction, Main problem of paraesophageal hernia comes from its complication; intestinal obstruction, volvulus, strangulation, and incarceration, as well as pulmonary aspiration. So, as soon as confirm diagnosis, it should be corrected surgically to prevent above complications, and sometimes it could result in serious condition. We have experienced paraesophageal hiatal hernia in 3-day newborn infant and have repaired it successfully. We used transabdominal approach to repair and to prevent reflux Nissen`s fundoplication was performed. We would report that with reference study.

Morgagni, in 1760, 1st. described the findings of substernal herniation of abdominal contents into the thoracic cavity, based upon 25 postmortem dissections. Herniation through the foramen of Morgagni is the rarest occurrence of the congenital diaphragmatic hernias and is usually a few symptoms. With the increasing use of routine chest roentgenogram & the need to exclude the possibility of a mediastinal neoplasm, most such cases are brought to the attention of a surgeon. We had experienced 2 cases of Morgagni hernia, which one caused a simple mechanical intestinal obstruction & diagnosed as acute appendicitis with perforation & another one was diagnosed as mediastinal lipoma on routine chest X-ray film at arrival due to traffic accident. We had performed left paramedian abdominal incision as misdiagnosis of acute appendicitis with perforation and repair of the defect and returned transverse colon & stomach into abdominal cavity in one patient. And in another patient, we preferred to approach through right thoracotomy incision and then left upper paramedian abdominal incision and returned the omentum into the abdominal cavity. The post-operative courses were in uneventful and we report these cases and review and discuss the literatures.

Palpable inguinal mass in children should be differentiated from inguinal hernia, hydrocele, lymph node, and tumor. Though using ultrasonography, fatty tumor would be misdiagnosed as incarcerated inguinal hernia containing fatty component. We experienced the huge inguinal lipoblastoma in 5-year-old girl mimicking recurrent incarcerated hernia. Laparoscopic exploration revealed it was not incarcerated hernia but well demarcated bulging mass from abdominal wall. Mass was about $10{\times}4{\times}3cm$ and extended from internal inguinal ring to saphenous opening. It was near total excised because of right external iliac vein injury. Pathologically, it was proven as lipoblastoma containing mature adipocyte with lipoblast and fibrous septa. Postoperatively, we noticed a segmental thrombotic occlusion of external iliac vein. After 1 year, she has no symptom related to occluded vessel. The remained lipoblastoma showed no interval change. Even lipoblastoma has a good prognosis with low recurrence rate, we need careful follow-up.

In this research, important mechanical characteristics of Compliant Press-Fit Pin and PHT are studied through the analysis of deformation mechanisms of Press-Fit Pin and by elastic-plastic finite element method. The direct data for the optimal design of pin was obtained without interfere with the criterion on insertion force and retention force. Also, the insertion force and retention force of new type pin were measured by precision type tensile testing machine and it revealed good agreement with analytical results. In conclusion, it is believed that above results will contribute satisfactorily to the practical design of Press-Fit Pin.
