Purpose: study of the mutual influence of the individual anatomical regions damage in patients associated with falls from heights. Methods: 561 medical reports of patients associated with falls from heights admitted to Republican Research Center of Emergency Medicine (RRCEM), in period of 2010-2013 yy, were analyzed retrospectively. Patient's age range was from 15 to 89. Treatment of these patients held in three stages: period of acute disorders of vital functions; relative stabilization period; stabilization of vital functions. The scope and content of medical diagnostic procedures performed on pre-hospital and intensive care stages. The severity of each injury was scored according to the AIS scale, the total severity of lesions was scored by points due to ISS. Digital material is treated by methods of mathematical statistics. Results: Falls from heights leads to associated injuries for 4 times more than isolated trauma, and increases according to height of fall and falling surface. Patients with TBI+chest trauma, are most serious contingent that has highest mortality and complications (36.8%). TBI+musculoskeletal system trauma are characterized by high blood loss, traumatic shock and fat embolism, forming a vicious circle. Conclusion: in patients associated with falls from heights clinical manifestations of injuries mutual aggravation syndrome will be seen. TBI leads to complication of chest trauma, delayed diagnostics of abdominal and chest trauma, aggravation of coma condition. Developing of high blood loss and fat embolism in musculoskeletal system trauma leads to shock and pulmonary embolism, which increases probability of death in the presence of abdominal or chest trauma, but abdominal trauma or chest trauma has no significant effect on the severity of the musculoskeletal system trauma.

Purpose: The purpose of this study was to identify effects of a tilting training program on lower extremities function, depression, and self-efficacy among stroke inpatients. Method: The subjects were 60'stroke patients hospitalized in an oriental medical hospital; 31 in the experimental group and 29 in the control group. A nonequivalent control group pretest-posttest design was used. The tilting training program consisted of 3 sessions and was implemented for 30 minutes daily during 3 weeks. Data was collected from Feb to July 2003, and analyzed by percentage, Fisher's exact probability, $\chi^2-test$, and t-test using the SPSS/Win 10.0 computerized program. Result: After treatment with the tilting training program, the experimental group was significantly increased in the mean score for function of lower extremities (t=2.72, p=.009) compared to the control group, especially for keeping standing balance (t=2.78, p=.007) and standing by oneself (t=3.32, p=.002). However, in the mean scores of depression and self-efficacy, there were no significant differences between the two groups. Conclusion: The tilting training program was effective for increasing the function of lower extremities and to improve walking ability earlier among stroke inpatients. Therefore, the tilting training program is applicable to increase the balance level in standing and walking ability at the early rehabilitation stage for stroke patients.

The purpose of the study was to find out the level of knowledge, attitude, subjective norm, social interaction, and behavioral intention of nursing students regarding AIDS. It also identified factors that predict behavioral intentions and to provide care for patients with AIDS using Theory of Reasoned Action. The subjects consisted of 117 nursing students at three universities. Data was collected with self reporting in a questionnaire of with 67 items. Data was analyzed by an SPSS pc+ program. The results were as follows; 1. The mean age of the subjects was 20.98 years. The mean score for HIV/AIDS knowledge was 24.444 out of 32. Mostly Korean students were quite knowledgeable about the basic facts and symptoms of AIDS but confused about the made of transmission such as public toilets, prevention methods, and especially infection control. 2. This study found that social interaction, attitudes and subjective norms of Korean nursing students explained the intention to care for AIDS patients. The students who had a more positive attitude toward caring for AIDS patients and those who perceived more support from their significant others for caring the AIDS patients reported a more positive intention to care for AIDS patients. 3. In stepwise multiple regression analysis, 47.58% of the variance in AIDS patient care intention was accounted for by social interaction (33.41%), attitude (9.1%), and subjective norm (5.0 %). According to the finding of this study, and social interaction are the most significant predictors of intentions. Therefore it can be suggested that a HIV/AIDS prevention program should focus on transmission modes and prevention methods, especially in infection control. AIDS education efforts aimed at nursing students should place greater emphasis on correcting these kinds of misconceptions. Nursing intenvention for reducing fear of contagion, improving perception of social interaction, fostering positive attitudes and increasing intention to care for AIDS patients should be provided for nursing students. They also recommended that nursing students be adequately prepared to care for AIDS patients because of the increasing probability that they will encounter AIDS patients. Therefore it is important that education about HIV/AIDS should be incorporated within current undergraduate curriculum.

Objective : The purpose of this clinical study was to investigate the effects of moxibustion on functional recovery in stroke patients. Methods : Forty two stroke patients were randomized into either the standard physiotherapy treatment combined with moxibustion group or a control group with standard physiotherapy alone. They were 8 weeks from onset to the start of this study. Moxibustion was applied at 合谷(LI14), 外關(TE5), 曲池(LI11), 太衝(LIV3), 懸鍾(絶骨,G39), 足三里(S36) in hemiplegic upper and lower extremity, once a day for 6 weeks. The effect of treatment on functional recovery was assessed using the Functional Independence Measure scale. Statistical significance was achieved if the probability was less than 5%(p<0.05). Result : These 2 groups had comparable clinical characteristics; sex, age, lesion, and pre-treatment FIM score. After 6 weeks, patients in the moxibustion group performed better on FIM. The differences were significant(P=0.001). Conclusion : These results suggest that moxibustion is an effective treatment for functional recovery in stroke patients.

Purpose: Although the duodenum and the pancreas are protected by surrounding organs and have a low probability of injury during trauma, the mortality and the morbidity due to complications is high. This report includes the pancreaticoduodenal injuries we observed that were treated at a single institute. Methods: The medical records of patients admitted to our institute between 2001 and 2012 for pancreaticoduodenal injury were retrospectively reviewed. Results: In our hospital, between 2001 and 2012, 15 patients were admitted for a pancreaticoduodenal injury. All patients experienced blunt trauma, 6 of whom were involved in traffic accidents and 9 of whom received injuries from physical assault. Most of the patients were men(13 of 15 patients, 86%) with a mean age of 23 years (range, 5?39 years). All patients were admitted to the emergency center and managed by the surgeons on duty. The mean value of the injury severity score was 22. The mortality rate was 6%(1 of 15 patients). Seven of the fourteen surviving patients(50%) had duodenal injury, 6 patients(42%) had a pancreatic injury, and 1 patient(7%) had a combined pancreaticoduodenal injury. The surgical procedures were targeted at damage control. Conclusion: In conclusion, we believe that damage control surgery is the optimal management for a pancreaticoduodenal injury.

Precipitation forecasts from MM5 have been verified for the period 1989-2001 over Yeongdong region to show a tendency of model forecast. We select 57 events which are related with the heavy snowfall in Yeongdong region. They are classified into three precipitation types; mountain type, cold-coastal type, and warm type. The threat score (TS), the probability of detection (POD), and the false-alarm rate (FAR) are computed for categorical verification and the mean squared error (MSE) is also computed for scalar accuracy measures. In the case of POD, warm, mountain, and cold-coastal precipitation type are 0.71, 0.69, and 0.55 in turn, respectively. In aspect of quantitative verification, mountain and cold-coastal type are relatively well matched between forecasts and observations, while for warm type MM5 tends to overestimate precipitation. There are 12 events for the POD below 0.2, mountain, cold-coastal, warm type are 2, 7, 3 events, respectively. Most of their precipitation are distributed over the East Sea nearby Yeongdong region. These events are also shown when there are no or very weak easterlies in the lower troposphere. Even in the case that we use high resolution sea surface temperature (about 18 km) for the boundary condition, there are not much changes in the wind direction to compare that with low resolution sea surface temperature (about 100 km).

Protein homology detection is an important issue in comparative genomics. Because of the exponential growth of sequence databases, fast and efficient homology detection tools are urgently needed. Currently, for homology detection, sequence comparison methods using local alignment such as BLAST are generally used as they give a reasonable measure for sequence similarity. However, these methods have drawbacks in offering overall sequence similarity, especially in dealing with eukaryotic genomes that often contain many insertions and duplications on sequences. Also these methods do not provide the explicit models for speciation, thus it is difficult to interpret their similarity measure into homology detection. Here, we present a novel method based on Word Conservation Score (WCS) to address the current limitations of homology detection. Instead of counting each amino acid, we adopted the concept of 'Word' to compare sequences. WCS measures overall sequence similarity by comparing word contents, which is much faster than BLAST comparisons. Furthermore, evolutionary distance between homologous sequences could be measured by WCS. Therefore, we expect that sequence comparison with WCS is useful for the multiple-species-comparisons of large genomes. In the performance comparisons on protein structural classifications, our method showed a considerable improvement over BLAST. Our method found bigger micro-syntenic blocks which consist of orthologs with conserved gene order. By testing on various datasets, we showed that WCS gives faster and better overall similarity measure compared to BLAST.

In this study, a deep learning-based tillage boundary detection method for autonomous tillage by a tractor was developed, which consisted of image cropping, object classification, area segmentation, and boundary detection methods. Full HD (1920 × 1080) images were obtained using a RGB camera installed on the hood of a tractor and were cropped to 112 × 112 size images to generate a dataset for training the classification model. The classification model was constructed based on convolutional neural networks, and the path boundary was detected using a probability map, which was generated by the integration of softmax outputs. The results show that the F1-score of the classification was approximately 0.91, and it had a similar performance as the deep learning-based classification task in the agriculture field. The path boundary was determined with edge detection and the Hough transform, and it was compared to the actual path boundary. The average lateral error was approximately 11.4 cm, and the average angle error was approximately 8.9°. The proposed technique can perform as well as other approaches; however, it only needs low cost memory to execute the process unlike other deep learning-based approaches. It is possible that an autonomous farm robot can be easily developed with this proposed technique using a simple hardware configuration.
