The purpose of this study was is leading landmark efforts to prevent the major causes of commercial-aviation fatalities about controlled flight into terrain (CFIT) in approach-and-landing accidents. The paper of major analysis for controlled flight into terrain (CFIT) was Guam accident, Mokpo accident and Gimhae accident in commercial transport-aircraft accidents from 1997 through 2002. CFIT occurs when an airworthy aircraft under the control of the flight crew is flown unintentionally into terrain, obstacles or water, usually with no prior awareness by the crew. This type of accident can occur during most phases of flight, but CFIT is more common during the approach-and-landing phase. The paper believed that prevention for CFIT accident was education and training for flying crew and upgrade for equipment such as EGPWS, and need more research for professional organizations of airlines.

Major analysis for controlled flight into terrain (CFIT) of Guam accident, Mokpo accident and Gimhae accident in commercial transport-aircraft accidents from 1993 through 2002 was made. CFIT occurs when an airworthy aircraft under the control of the flight crew is flown unintentionally into terrain, obstacles or water, usually with no prior awareness by the crew. This type of accident can occur during most phases of flight, but CFIT is more common during the approach-and-landing phase. Key prevention for CFIT accident was education and training for flying crew and to upgrade for equipment such as EGPWS, and the need for more research by professional organizations of airlines.

There have been many reports about infections in patients with rheumatoid arthritis (RA) being more frequent than general population. Increased susceptability to infections in RA could be related to disease itself, comorbid conditions, and use of immunosuppressive drugs and steroid. Herpes zoster viral infections also have been reported to be more frequent in RA. We describe a case of 60-year-old woman with RA presented with ophthalmoplegia associated with herpes zoster ophthalmicus. Initially she complained of right orbital and periorbital pain. Six days later, she noted a cutaneous herpes zoster eruption involving the right 1st division of trigeminal nerve. Three days after developing skin eruption, she developed a right ptosis with external ophthalmoplegia and pupil dilatation resulting from the 3rd and 6th cranial nerve involvement. She was placed on intravenous acyclovir for 7days. Eight weeks after the onset of ophthalmoplegia, she recovered nearly completely.

Since beginning with the first organ transplantation from brain-dead donor in 1979, organ transplantation has been developing continuously in Korea. However, organ shortage still is a serious problem in the field of solid organ transplantation. For this reason, it is necessary to promote deceased donor organ transplantation and achieve self sufficiency. There are two system requirements managing deceased donor organ transplantation; operational and regulatory systems. In operational system, mutual and balanced cooperation between transplantation centers, organ procurement organism (OPO), registration/allocation system and NGOs is one of most important determinants to maximize brain dead donor. Especially, transplantation center and OPO need to improve in their organ donation process through evaluating donation practices and developing critical pathway for each step. In addition, public education program focusing on the hospital staff, the family of deceased donors and students should be enhanced to increase public awareness for organ donation. In regulatory system, national transplantation authority for the transplant coordination among various structures and policy-making on the issue of organ donation is necessary. For this purpose, Korean Network for Organ Sharing (KONOS) has to be improved into professional and authoritative body and establish more expanded national database network system. Further improvement in operational and regulatory systems to activate organ donation could enable to achieve the Asian leadership in the field of transplantation as well as self sufficiency for organ transplantation.

BACKGROUND/AIMS: We aimed to evaluate the cost-effectiveness of preoperative stent insertion for treating left-sided malignant colorectal obstruction. METHODS: Patients with left-sided malignant colorectal obstruction were included in this study. The stent group (ST, n=24) included those patients who were treated with preoperative stent insertion followed by curative surgical resection. The clinical course and management cost of the ST group was compared to those of the emergency operation group (EO, n=22). RESULTS: The patients' age (60.6+/-3.1 yrs vs. 62.1+/-3.2 yrs, p=0.74) and the male to female ratio (12:12 vs. 15:7, p=0.25) were not different between the ST and EO groups. The distribution of the postoperative pathologic stages was also not different. All the patients in the ST group underwent only one surgical operation, while 6 patients (27.3%) in the EO group underwent 2 or more surgeries (p<0.01). The mean hospital stay in the ST group was 22.0+/-0.8 days compared to 26.3+/-2.4 days in the EO group (p=0.09). Postoperative care in the intensive care unit was necessary for one patient (4.2%) in the ST group, while 7 patients (31.8%) in EO group needed postoperative care (p=0.02). Postoperative complications developed in one patient in the ST group, while 6 patients in the EO experienced postoperative complications (p=0.04). The mean total cost per patient was 7,974,236 won for the ST group while this was 9,271,630 won for the EO group (p=0.06). CONCLUSIONS: Preopreative stent insertion for treating left-sided malignant colorectal obstruction is more cost-effective than an emergency operation.

With an aging population, the number of patients with difficulty in swallowing due to medical conditions is gradually increasing. In such cases, enteral nutrition is administered through a temporary nasogastric tube. However, the long-term use of a nasogastric tube leads to various complications and a decreased quality of life. Percutaneous endoscopic gastrostomy (PEG) is the percutaneous placement of a tube into the stomach that is aided endoscopically and may be an alternative to a nasogastric tube when enteral nutritional is required for four weeks or more. This paper is the first Korean clinical guideline for PEG developed jointly by the Korean College of Helicobacter and Upper Gastrointestinal Research and led by the Korean Society of Gastrointestinal Endoscopy. These guidelines aimed to provide physicians, including endoscopists, with the indications, use of prophylactic antibiotics, timing of enteric nutrition, tube placement methods, complications, replacement, and tube removal for PEG based on the currently available clinical evidence.
