The purpose of this study was to examine the effect of difficult endotracheal intubation education in the 119 rescue services. The subjects in this study were 60 members of the 119 rescue services that was under the umbrella of the Fire Service Headquarters of J province. A SPSS 14.0 program was utilized to find out the effect of tough tracheal intubation education on their relevant knowledge, self-confidence, academic self-efficacy and technical Performance in consideration of general characteristics. The findings of the study were as follows: 1. They showed a significant improvement in all the knowledge, self-confidence, academic self-efficacy and technical Performance after they received that education. 2. As for connections between general characteristics and knowledge before and after that education, there were significant differences in their knowledge according to gender and career of working in the hospital, and their rank and career of working in the hospital made a significant differences to their self-confidence. Their academic self-efficacy significantly differed with rank, career of working in the hospital and academic credential. There were significant gaps among them technical Performance Case 1 according to career of working in the 119 rescue services, and technical Performance Case 2 significantly varied with age and academic credential. There were significant gaps in technical Performance Case 3 according to career of working in the 119 rescue services and career of working in the hospital after that education was provided, and technical Performance Case 4 significantly varied with age and rank before and after the education was conducted. In conclusion, the kind of education programs that aim at stirring up the interest of the 119 rescue services in advanced airway and helping the members learn about tracheal intubation accurately with confidence is urgently required.

Background : Nowadays asthma is considered to be the inflammatory disease characterized by airway hyperresponsiveness and pulmonary eosinophilia, and mediated by Th lymphocytes expressing the Th2 cytokine pattern. In many recent studies, molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of asthma. Objective : We aimed to identify the effect of Armeniacae Arnarum Semen and Platycodi Radix on the transcriptional activities of cytokine IL-4, IL-5 and IL-6 involved in asthma model. Materials and Methods : RBL-2H3 cell lines were used. Cells were stimulated with calcium inophore for maximal gene expression. After 24 hours of Armeniacae Arnarum Semen and Platycodi Radix-treatment, total cellular RNAs were collected using Trizol solution method. Then transcriptional activities of IL-4, IL-S and IL-6 were measured by RT-PCR with electrophoresis. Results : In IL-4 study, Armeniacae Arnarum Semen treated group showed 48.4% of transcriptional activities compared to the control group and Platycodi Radix treated group showed 45.4% of transcriptional activities compared to the control group. In IL-5 study, Armeniacae Arnarum Semen treated group showed 52.7%of transcriptional activities compared to the control group and Platycodi Radix treated group showed 60.2% of transcriptional activities compared to the control group. In IL-6 study, Armeniacae Amarum Semen treated group showed 42.3% of transcriptional activities compared to the control group and Platycodi Radix treated group showed 69.1% of transcriptional activities compared to the control group. Conclusion : This study shows that Armeniacae Arnarum Semen and Platycodi Radix have the inhibitory effect on the transcription of IL-4, IL-5 and IL-6 gene expression in RBL-2H3 cell lines. Advanced studies are required to investigate the mechanisms of inhibition by herbal medicine in asthma model.

In general, the patients who transferred to the hospital by 119 rescue service at night go to the emergency room(ER) of general hospital rather than that of their nearby the 1st(clinic) and 2nd(local hospital) hospital. And the hospital is mainly selected not by 119 EMST but by patients or his/her conservators. Therefore we had studied retrospectively with emergency situation diary and medical chart for 697 patients of being transferred to one emergency medical center for 6 months since January 2004, and results are as follows. 1. The 280 patients(42.5%) of being transferred hospital at night by 119 rescue service were not emergency case and their average staying time in hospital was about $7.15{\pm}10.06$ minutes. 2. Transfer time was distributed in each time intervals of 1819, 2021, 2223, and 2401 and patients ratio in each intervals were 15.1%, 17.8%, 16.4%, and 15.2%. 3. In response of ambulance, the average time from the spot to the hospital was $14.53{\pm}9.27min$. and average distance of that was $7.95{\pm}9.21km$. 4. Diseases rather than traffic accidents or traumatic injury were main causes of ambulance calling and its value was 533(76.5%), and accidents were mainly occurred in patients' house and its value was 479(68.7%). 5. In time of transfer by 119 rescue service, hospital was mainly selected by patient/conservator and its value was 648(93.0%). In result. the hospital was selected not by EMST but by patient/conservator. 6. The case that the 1st grade EMT was rode in ambulance was 161(23.1%), and the case that 2nd EMT and emergency team member who educated for emergency were rode in ambulance were 504(72.3%). So the number of the 1st grade EMT was short in fire station of Kwangju metropolitan city than other city. 7. The first aids for patients before reaching hospital were limited to oxygen inhalation, airway control, and BLS for maintaining limbs and spine. So it seems to be a simple patients transfer. Consequently, to establish an efficient emergency medical system, it has been thought that it should be advanced a moderate education and public information about the appropriate use of emergency medical system toward citizen, and also need the hospital selection by the patients categorizing standards for 119 rescue service member, securing the 1st grade EMT, appropriate first-aids education, and securing professional human power in emergency room of the Ist(clinic) and 2nd(local hospital) hospital at night.

This study analyzed current prehospital emergency care for severe trauma patients administered by different number of 119 EMS (emergency medical services) teams. Out of 1,067 severe trauma patients transferred by 119 EMS teams in J province from January 1st to December 31st 2015, 438 were evaluated in this study. IBM SPSS Statistics 21.0 was used to analyze collected data. The number of patients with severe trauma during the period of study was higher in male with two and three ambulance crews of 119 EMS teams with 242 patients (70.6%) and 66 patients (69.5%) respectively. The percentage of transfers made to local emergency medical centers was highest in those two groups, being 44.0% (151 patients) and 49.5% (47 patients), respectively. Total time spent at the scene did not differ between ambulance crews of two and three, nor did the frequency of practicing advanced airway management and IV (intravenous) cannulation, or the success rate of IV cannulation (p=0.253, p=0.362, p=1.000). Overall, the results indicated that merely increasing the number of paramedics does not improve the quality of prehospital care for severe trauma patients. Measures such as securing professional paramedics, simplifying direct medical oversights, activating indirect medical oversights, and expanding the legally allowed work scope are required.

The purpose of this study was to investigate the changes of the pharyngeal space when the following appliances were inserted: the mandibular advancement appliance (MAA), tongue retaining appliance (TRA), and mandibular advancement-tongue retaining appliance (MATRA). Nine male dental students exhibiting Class I occlusion, normal body mass index (BMI), and no signs and symptoms of snoring were selected for this study. The three kinds of snoring appliances (MAA, TRA and MATRA) were fabricated for each subject. The mandibular advancement of the MAA and MATRA was set at a distance of 5 mm, and the TRA and MATRA were made to hold the tongue in front of the maxillary incisors by 10 to 20 mm. Lateral cephalometric radiographs of the following four states - with no appliance, MAA, TRA, and MATRA - were taken to examine any anatomical changes resulting from the application of the appliances. All four radiographs were traced and analyzed for twenty selected variables related to the pharyngeal space, cranio-cervical posture, and position of the soft palate and hyoid bone. According to the results of this study, there were significant increases in both the upper and lower oropharyngeal spaces when the mandible and tongue were protruded simultaneously, although there was a significant increase only in upper oropharyngeal space when the mandible or tongue was advanced separately. In conclusion, it is suggested that the MATRA may result in more positive effect on the control of snoring and OSA compared to a single use of the MAA or TRA, especially for the patients whose upper airway obstruction occurs in the lower oropharynx.

The author obtained some useful information for the class III treatment from long term observation on the growing patients with class III malocclusion. 8 patients were selected for this study and presentation. From these observation so far my conclusions might be as follows: First in the early correction of the anterior crossbite, considerable forward growth changes were observed in the maxilla Second, as for the growth modification of jaws by orthopedic treatment only limited effects were recognized from the long-term observation Thrid, at early age of patients with anterior crossbite, any data couldn't make me predict the stability after treatment on the long-term basis. Fortunately, however, genial angle showed a marginal possibility of it prediction. Fourth, at an advanced age/ retraction orthopedic force on the mandible and the rapid change in the mandibular position may cause some trouble in the T.M.joint. Finally, the followings are recommendable. As for the anterior crossbite, correct it early as possible, and use orthopedic force under the age of ten. Do not enter the phase II treatment directly. Just wait and observe until the growth were almost completed, focusiong on some important factors such as airway problem, tongue position, and third molar development. Of course, these factors may have some effects on the mandibular growth. for the female, at the age of around 14 years old and the male, around 17 years old, make a final decision whether the patients will continue to be treated orthodontically or surgically Thereby, (I think) the relapse and retreatment problem after treatemnt we have observed so far might be minimized. Furthermore, the active treatment time may be also reduced.

In 1994, the North Korea indicated their intention to open up airspace. The air route passing through from Daegue FIR to Pyungyang FIR has established in 1996. The air transport cooperation between South and North Korea seemed to be reinforced at the event of President Kim, Dae-Jung's visit to North Korea by passing through a temporarily established Yellow Sea Airway in the year of 2000. The nature characteristics of air transport burdening of many circumstantial situations, however, have kept cooperation between South and North Korea from being facilitated till now. Recently as the more exchange between North and South Korea, the more frequent opportunities to discuss economic cooperation, which in sequence increased political credibility has been increased. The rail, road, and port reconnecting has realized which have been regarded impossible. Furthermore, it is expected to transport personnel and goods through South-North direct connected routes in the near future This study shows several meanings of air transport cooperation between South and North Korea. It will be far beyond simply partial air route connecting in this region, it gives great significance to realize economic cooperation and Northeast hub through air transport industry sector. This will be an exit for air transport industry have suffered limits derived from North Korea troubles and difficulties in growing as Northeast air hub. Namely, South-North air connection denote its meaning in providing opportunities Korea to be Northeast Hub and advanced country having globally competitive air transport industry To develop strategy for air transport cooperation between South and North Korea. they were developed by SWOT analysis on the basis of circumstantial analysis. These strategy need to be commanded properly to the changes of surrounded circumstances. The study result show it is desirable to apply phasal strategies by using strengths, weaknesses, threats and opportunities factors underlying analysis of inner and outer circumstances to cooperate in air transport sector.

Background : The incidence of lung adenocarcinoma, which is more prevalent in women and nonsmokers, is increasing. The aim of this study was to determine the prognostic factors of an adenocarcinoma of the lung. Material and method : The clinical information of patients diagnosed with an adenocarcinoma of the lung at the Kosin University Gospel Hospital from January 1994 to July 2004 was reviewed retrospectively. The survival time of these patients was analyzed by the patient's age, gender, performance status, weight loss, smoking history, location of the primary tumor, clinical stage, serologic tumor markers, and treatment modality. Results : For all 422 patients with an adenocarcinoma of the lung, 247 (58.5%) were male, and their mean age was 59.8 years the. The majority of patients were smokers (58.3%), and the tumors were located in the periphery (59.7%). In the smokers, the tumor was located more in the central airway compared to the non-smokers (42.8% vs. 31.9%, p=0.12). The overall median survival time was 390 days (95% CI;304-436 days). Univariate survival analysis revealed that an older age (${\geq}65$ years old), male, weight loss, smoker, central type, advanced clinical stage, elevated serum carcinoembryonic antigen (CEA, >5 ng/ml) and neuron specific enolase (NSE, >15 ng/ml), and the supportive care only were significantly poor prognostic factors. The median survival time was shorter in the smokers than nonsmokers (289 days vs. 533 days, p<0.001). In addition, it was also shorter in the elevated NSE group than in the normal range group (207 days vs. 469 days, p<0.001). Multivariate analysis showed that age, clinical stage, serum NSE, smoking status, and treatment modality were independent predictors of survival (hazard ratios: 1.68, 1.94, 1.92, 2.39 and 1.57, respectively). Conclusions : Smoking is an important prognostic factor in an adenocarcinoma of the lung, but not gender. This suggests that the better prognosis of women is more related with the lower rate of smoking. In addition, the elevated serum NSE is also an important prognostic in an adenocarcinoma of the lung.
