Purpose: This study intended to improve quality of prehospital emergency care for trauma patients by figuring out its current situations and problems based on run-sheets and questionnaires of 119 emergency medical technicians (EMTs). Methods: This study conducted a research of 425 trauma patients transferred to the 3rd hospital in G-city by 119 ambulances from July 1, 2008 to June 30, 2009. We aslo utilized 114 copies with questionnaires of 119 EMTs working in J-province. The data were analyzed with SPSS 18.0. Results: There were 425 trauma patients including 272 men and 137 patients with traffic accident. When it comes to types of 119 EMTs who delivered cares to patients, there were 206 (48.5%) advanced EMTs, 101 (23.8%) basic EMTs, 50 (11.8%) nurses and 43 (10.2%) rescue education receivers. The most frequent measured vital sign was pulse rate (54.1%). Regarding assessment of systolic blood pressure, pulse rate and respiration rate, there were some significant differences in accordance with type of 119 EMTs. Among the 317 patients evaluated 'emergency' in field, 137 patients returned to their home. Prehospital emergency cares accounted for 861, around 2.0 treatments per a patient. In view of questionnaire, the 74.6% of 119 EMTs hoped supplement of man power for proper prehospital care to trauma patients. Conclusion: This study suggested that it is necessary to develop detailed guidelines for trauma patients so as to improve quality of trauma patient evaluation and prehospital care. Furthermore, improvement of emergency care systems will reduce mortality of trauma patients and lead to their good outcome.

Participants of this 1998 survey included 100 physical therapists working in hospitals located in Andong City. 77.7% of the participants were in their twenties and 20.2% in their forties. 46.4% of the participants were 3rd year students at a junior college, and 1.0% were college graduates. 67.6% of the participants had less than 5 years experience and 1.0% 16 years experience in their field. 59.6% of the participants were married. Regarding questions about occupational satisfaction, many of the participants replied "normal" for the first and third questions, and few answered "very much". Most of the participants answered "normal" for all the questions concerning their work environment with few replying "very much". With regards to awareness of the physical signs of fatigue, "occasionally, yes" were the most frequent answers. Regarding awareness of the psychological signs of fatigue, the similar proportions of participants answered "occasionally, yes" as that for "feeling nothing". Similarly, with regard to awareness of the neuro-sensitive signs of fatigue, there was a similar ratio of participants answering "occasionally, yes" and "feel nothing". It can be concluded that there are many causes of fatigue amongst physical therapists. Improvements in daily nutrition, mental health and general well-being are important in tackling these problems. It appears that fatigue amongst physical therapists may be cumulative and due to prolonged working hours To promote better daily functioning and early recovery from fatigue, appropriate assignments of working and resting hours are necessary. They would also benefit the prevention of symptomatic problems in the waist and shoulder.

In order to prevent traffic accident, it is very important that the driver regulates the location of rear view mirror using the automatic seat regulation system which guarantees the maximum vision of the possibility for accuracy. In order to solve this problem the paper deals with the automatic seat control system which guarantees comfortable and safe seating and good visual field. Also a automatic car seat control algorithm has been developed to regulate the back mirror. Particularly, the automatic seat control algorithm function for the air bag operation in case of an accident has been added depending on passengers weight. Moreover when the driver passes a dangerous area an algorithm has been developed which gives the driver a naming sign and has been simulated in a ubiquitous environment. The simulation result proved that the Intelligence analysis for traffic accidents can reduce franc accidents more than 25% than the currently existing methods.

The purpose of this study is to elicit preference for drug listing decision criteria and to estimate the ICER threshold in South Korea using the discrete choice experiment (DCE) method. To collect the data, a DCE survey was administered to a subject sample either educated in the principle concepts of pharmacoeconomics or were decision makers within that field. Subjects chose between alternative drug profiles differing in four attributes: ICER, uncertainty, budget impact and severity of disease. The orthogonal and balanced designs were determined through computer algorithm to take the optimal set of drug profiles. The survey employed 15 hypothetical choice sets. A random effect probit model was used to analyze the relative importance of attributes and the probabilities of a recommendation response. Parameter estimates from the models indicated that three attributes (ICER, Impact, Severity of disease) influenced respondents' choice significantly(p${\pm}$0.001). In addition, each parameter displayed an expected sign. The Lower the ICER, the higher the probability of choosing that alternative. Respondents also preferred low levels of uncertainty and smaller impact on health service budget. They were also more likely to choose drugs for serious diseases rather than mild or moderate ones. Uncertainty however is not statistically significant. The ICER threshold, at which the probability of a recommendation was 0.5, was 29,000,000 KW/QALY in expert group and 46,500,000 KW/QALY in industry group. We also found that those in our sample were willing to accept high ICER to get medication for severe diseases. This study demonstrates that the cost-effectiveness, budget impact and severity of disease are the main reimbursement decision criteria in South Korea, and that DCE can be a useful tool in analyzing the decision making process where a variety of factors are considered and prioritized.

Comics are a genre that convey meaning through compositional arrangements of dialogue and images as well as through the flow of panels across a page. Communicating that meaning to readers through a combination of language and visual lexicons is the essential process of drawing comics, a process that in itself is significant. The semiotics of comics is a field of scholarship grounded in the broader discipline of semiotic theory in which all the components of comics, both visual and verbal, are the subject of study and research. By adopting a semiotic approach we are able to objectively analyze and understand the symbolic, social and ideological meanings embedded in the signs and sign processes expressed in comics. The fundamental pedagogical mission of teaching comics is to cultivate human nature through the study of theory as well as through the production and completion of original works that explore new modes of expression. To go further, interpreting those embedded meanings in the context of comics fosters effective and creative skills of expression that go beyond a mere fascination for the genre itself. In short, because the semiotic approach to understanding visual communication is the essence teaching comics, we can expect that the act of reading and creating comics plays a significant role in understanding visual communication.

Duck viral hepatitis is an acute, highly infectious viral disease of young dacklings aged from two days to three weeks. The significant lesion associated with the disease was enlarged liver including necrotic foci and numerous hemorrhagic spots. We have isolated five strains of duck hepatitis virus (DHV) from field cases showing about 20% mortality with a sign of opisthotonos. When a-day-old ducklings were intramuscularly inoculated with one of the isolates, 92% of the birds were died within 5 days. We attempted to develop an attenuated strain of duck hepatitis virus (DHV) using one of the isolates by serial chicken embryo passages. The propagation of DHV in chicken embryos was carried 140 passages. The virus titer increased gradually from the $21^{st}$ through the $50^{th}$ passage, but there was no significant increase of virus titer in subsequent passages after then. Through the serial passages, the virulence of the virus for chicken embryos was gradually increased but decreased for ducklings. The pathogenicity of the virus for ducklings was preserved up to the $21^{st}$ passage but disappeared at the $50^{th}$passage. An attenuated Korean isolate which was passaged 140 times in chicken embryos gave good protection in ducklings against both challenge infection to a Korean virulent strain and to a DHV-DRL strain, a type 1 reference strain of DHV, which indicated that the Korean isolates could be classified as DHV type 1. And the above results suggest that an attenuated Korean isolate can be used for developing a live DHV vaccine.

The legal relationship between patient and physician is legally equal relationship. But, in times past, patients be compelled to sign an unequal contract, substantially. Because of the imbalance between supply and demand in the health care market. Today, the law of supply and demand in the health care market is running well. And as the cognition of citizens' rights grows, the relationship between patient and physician can also get a lot of changes. Patients have the right to know the information about medical care, and to decide whether or not to get treatment including invasions against their own bodies. In other words, Doctors have an obligation to explain to their patients. If doctors did not provide patients sufficient explanation or information, it violates the right of patients. This is a tort, or a breach of contract. To improve the remedy for violation of patient's right, patient is able to be protected by status as consumer. If patient is a kind of consumer in terms of medical consumption, he/she as consumer can enjoy supplementally the consumer's right. The patient as a consumer can exercise now a consumer's right as a constitutional right. In addition, with respect to consumer's rights, Framework Act on Consumers was enacted. This Act is based on constitutional provisions of Article 124 and the Act can be seen as a law that embodies consumer right because the provision of the constitutional law delegates specific contents. In the health care field, patients need to win recognition the statue of the consumer to hold the sovereignty of the consumer. In particular, if patients are consumers, they may be able to make good use of the quickly and efficiently collective dispute resolution and association lawsuit to rescue their damage, the Alternative Dispute Resolution(ADR) of Framework Act on Consumers.

Most video coding systems use YCbCr color space for their inputs, but RGB space is more preferred in the field of high fidelity video because the compression gain from YCbCr becomes disappeared in the high quality operation region. In order to improve the coding performance of RGB video signal, this paper presents an adaptive frequency-selective weighted prediction algorithm. Based on the sign agreement and the strength of frequency-domain correlation of residual color planes, the proposed scheme adaptively selects the frequency elements as well as the corresponding prediction weights for better utilization of inter-plane correlation of RGB signal. Experimental results showed that the proposed algorithm improves the coding gain of around 13% bitrate reduction, on average, compared to the common mode of 4:4:4 video coding in the state-of-the-art video compression standard, H.264/AVC.

The long term plan for apartment housing has a important role to make a decision making whether a repair work should be done or not. But, items for repair works are so various that field workers could not understand the context or plan the repair cost and time. These difficulties are drawn from the number of repair items, duplicated application and meaning, new material application and technology time-gap. Therefore, it needs to change or coordinate the repair items to improve the repair condition, reflecting the current material level or repair technologies. In this paper, it aimed at coordination of the repair items through the repair recording sheet which was surveyed in 22 metropolitan areas of Seoul, conducted between 2011 and 2014. The surveyed data are classified into six categories such as building exterior, building interior and so on, according to long term repair plan and the number of data are 1,918. It analyzed the appearing word for repair-concerned and compared the existing items of the long term plan. Items of building exterior are proposed as roof, exterior wall and painting. Building interior has a little meaning to propose the repair items. The water supply facilities are proper to keep the existing repair items. Items of the outdoor facilities could not need a sign board, drainage root and PVC sheath. Through this study, we can coordinate the repair items in apartment and provide the repair item and cost level.
