This paper reviewed the diving standards for underwater work in hostile environment and analyzed applied Navy diving technique, diving equipments and procedure for rescue operation of Navy ship Cheonan's missing crew occurred near Bak Ryung Do in March 2010. The operation was done beyond the international standards and safety practice, and by considering the nature of the mission, urgency and effectiveness as well as the detailed facts such as duration and depth of the dive, type of work to be performed, environmental conditions, time constraints of early rescue operation, it is analyzed that using air scuba diving system was adequate.

The efficiency tests of automatic positioning transmitter (APT) using satellite on life jacket were carried out to minimize casualties of fishermen and to make system optimization for effective SAR (Search and Rescue) operation. As the result of the tests, average position was equaled on the comparison between SPOT using low earth orbit satellite and DGPS (Differential Global Positining System), but standard deviation of DGPS for latitude and longitude were 66.4% and 46.3% smaller than those of SPOT. The position precision of SPOT was almost two times lower than LGT using geostationary satellite to compare 95% circular error probability. However, the success rate of receiver for SPOT was revealed as 86.5~94.1% on the experiments in the South Sea and the West Sea and it was 4.5 times higher than LGT. Therefore, SPOT is expected to contribute greatly to the rapid rescue of victim.

Clinostomum (C.) complanatum is one of the trematode helminthes in birds and causes incidental infection in human. A black-tailed gull (Larus crassirostris) was referred to the Jeju wildlife rescue center. Because of the death of bird after two weeks treatment, necropsy was performed to the bird. Grossly, many living worms adhered to the oral mucosa including pharynx and esophagus were observed. The worms removed were identified as C. complanatum after morphological observation. The linguiform adult worms were $5.19{\pm}0.48mm$ long and $1.80{\pm}0.18mm$ wide. Histopathologically, severe necrosis and surrounding inflammation were observed at the infection sites of adult worm in pharynx and esophagus. This is the first report for C. complanatum infection in wild black-tailed gull in Korea.

Purpose: The purpose of this study was to identify relationship between knowledge and infection control behavior about Hepatitis B patient in health care-related majors. Methods: Data was collected from health care related majors-nursing, emergency rescue and dental hygiene with questionaire. Total respondents were 306 and we use all of them. We analysed students' knowledge and infection control behavior about Hepatitis B patient and their relationship. Uni-variate analysis, t-test, ANOVA and correlation analysis test were conducted using SAS version 9.2. Results: Students who go the Hepatitis B lecture were significantly high Knowledge level about Hepatitis B(p<.05). Students who go to clinical education about Hepatitis B were significantly better behavior about infection control in clinical practice(p<.05). The relationship between knowledge about Hepatitis B and infection control in clinical practice was significantly negative(p<.05). Conclusions: It needs to be educated both infection control lectures and clinical practice to health care-related majors to prevent cross-infection between patients and health care providers.

Open reading frame 4 of Bombyx mori nucleopolyhedrovirus (BmNPV), designated as Bm4, is a gene whose function is completely unknown. With the recently developed BmNPV bacmid and a modified pFastBac1 whose polyhedrin promoter was replaced with ie1 promoter, a recombinant bacmid expressing Bm4-EGFP fusion protein under the control of ie1 promoter in BmN cells was successfully constructed. The result not only showed that the polyhedrin promoter can be replaced efficiently with other promoters to direct the expression of foreign gene in BmN cells by using Bac-to-Bac/BmNPV baculovirus expression system but also laid the foundation for rescue experiment of Bm4 deletion mutant due to the ability of ie1 promoter to direct gene expression throughout the infection cycle.

In this study, an educational game named "Jumbini 2: Mountain Rescue Operation" is compared and analyzed as a case of highly effective educational as well as significant popular game. In order to develop effective game software for education, stories and structure elements of the game are examined. Significant results are found on aspects of value and effect as an educational game, analyzing based on goal, rule, competition, challenge, fantasy, safety and fun, which are general elements for educational games.

This research paper surveyed the awareness of general administrative officials who oversee the disaster management and firefighting officials who take part in emergency rescue work in local governments on disaster response exercises. The result of the survey showed that both officials acknowledged the need of the equipment used in disaster response exercises, securing the budgets for exercises, establishing a network among related institutions, reflecting actual conditions and local characteristics to the exercises, reflecting the result of exercise evaluations to the disaster response manual and next exercises, and securing a command communication system required for exercises.

This paper introduces a mobile robotic system being developed for urban search and rescue. In order to search human victims in narrow spaces, we developed two types of serially linked mobile robots, named KAEROT-Centipede and KAEROT-SnakeTV1, that can climb over large vertical steps or travel inside narrow vertical pipes. To send such mobile robots to the disaster areas coping with large obstacles, we also developed a assistant mobile robot, named KAEROT-QuadTrack, that has 4 articulated track modules. This paper describes the mechanical structure and control architecture of the serially linked mobile robots and the supporting configuration for torque reduction of the assistant mobile robot during spinning motion that usually requires large driving torque. The experimental results show that such robotic systems have good mobility over the various terrains in disaster areas.

Prader-Willi syndrome (PWS) is a complex multisystem genetic disorder characterized by hypothalamic-pituitary dysfunction. The main clinical features include neonatal hypotonia, distinctive facial features, overall developmental delay, and poor growth in infancy, followed by overeating with severe obesity, short stature, and hypogonadism later in development. This paper reviews recent updates regarding the genetic aspects of this disorder. Three mechanisms (paternal deletion, maternal disomy, and deficient imprinting) are recognized. Maternal disomy can arise because of 4 possible mechanisms: trisomy rescue (TR), gamete complementation (GC), monosomy rescue (MR), and postfertilization mitotic nondisjunction (Mit). Recently, TR/GC caused by nondisjunction at maternal meiosis 1 has been identified increasingly, as a result of advanced maternal childbearing age in Korea. We verified that the d3 allele increases the responsiveness of the growth hormone (GH) receptor to endogenous GH. This paper also provides an overview of endocrine dysfunctions in children with PWS, including GH deficiency, obesity, sexual development, hypothyroidism, and adrenal insufficiency, as well as the effects of GH treatment. GH treatment coupled with a strictly controlled diet during early childhood may help to reduce obesity, improve neurodevelopment, and increase muscle mass. A more active approach to correct these hormone deficiencies would benefit patients with PWS.

To provide an easy operation of drift prediction model in SAR(search and rescue) mission a GUI program running on Window environment has developed. Users can make choice of input data on the screen by just clicking the mouse and the prediction results of datum points and trajectories of vessels are drawn on the map. The program contains both Leeway Equation model and mathematical model. The FORTRAN language was used in programming and Lehay Winteracter 4.0 software was utilized for graphic presentation. The result of May, 2001 Busan field experiment was plotted with that of model prediction for demonstration purpose.
