This study was conducted to determine the injury type and frequency of bearded dragons during single and group breeding according to stocking density, for 16 weeks. A total of 14 bearded dragons compromising three groups were selected for this study. Six and four bearded dragons bred in a cage of 45 cm × 45 cm × 45 cm were designed as group A and B, respectively. Group C was made of four partitions (20 cm × 20 cm × 20 cm) of equal size in the kennel, and the dragons, four in number, were reared alone. Injury type criteria were given 1 score each in 6 stages. Most of the injury types in group A were primary tail cutting, which was 1 point, depending on the score, except for 4 scores. The injury type of group A varied, that is 1, 2, 3, and 5 scores, and the pattern lasted for 2 to 9 weeks. After 10 weeks, the dragons showed no response to injury type, except 4 scores at 11 weeks and 2 scores at 14 weeks with a frequency of one, respectively. The representative injury types of the group B were primary tail cutting, which was 1 point, and the scores of the injury type from 2 to 11 weeks were the highest; the frequency of occurrence at 1 and 2 scores was 5 times and 3 times, respectively, and the frequency of occurrence at 3 scores was twice. In addition, 5 scores were found to have the lowest frequency of occurrence. Solitary breeding showed no response to the type of injury for 16 weeks. Consequently, single breeding with an appropriate stocking density did not affect stress, and it could be expected a positive aspect for pet welfare.

Recently supporting policy of government for agricultural is changing from individual to workplace. For this reason, the number of industrial injury is increasing due to increase workplace in the agriculture. However, because the studies on the characteristics and causes of injury have not been performed, the effective measure for the prevention of industrial injury is difficult to establish. The aim of this study is to analyze the industrial injury characteristic and prepare the effective counterplan to prevent industrial injury of the workplace in the agriculture. This study analyzed 2,970 cases of industrial injury during the last five years (2008-2012) in the agriculture sector. The data was offered by Korean Occupational Safety and Health Agency. The results of analysis the industrial injury characteristic of the workplace in the agriculture, number of industrial injury for source of industrial injury was 12.3% in the outdoor floor and injury type was 23.1% in the fall. This study analyzed industrial injury characteristic which size and type of workplace, injury type and source of industrial injury through the case of industrial injury in agriculture. The result of this study will be helpful to identify the industrial injury characteristic in the agriculture and prepares the effective industrial injury prevention method.

In the animal model of acute respiratory distress syndrome (ARDS) induced by N-nitroso-N-methylurethane (NNNMU) the secretory activity of alveolar type H cells during acute alveolar injury was investigated by determining phospholipid and pulmonary surfactant associated proteins in crude surfactant. The mechanism of the secretory change was studied by determination of DNA and RNA levels in the lung tissue. After induction of acute alveolar injury with NNNMU, pulmonary hemorrhage, atelectasis and gross hypertrophy were observed. Seven days after NNNMU treatment the level of total DNA in lung homogenate was increased markedly indicating that a hypertrophy was induced by cellular proliferation. Although the total DNA level increased, the RNA/DNA ratio was gradually decreased after NNNMU treatment. Seven days after NNNMU treatment the RNA/DNA ratio returned to the normal control level. During the acute alveolar injury, phospholipid and surfactant associated proteins were reduced significantly as compared with the control, implying that the secretory activity of alveolar type II cells was altered during acute alveolar injury induced by NNNMU. The protein content in crude surfactant during peak injury(7 days after NNNMU) was decreased significantly but phospholipid/protein ratios were identical in both control and NNNMU treatment groups. SDS-PAGE of proteins in crude pulmonary surfactant showed a decrease in major surfactant associated protein(M.W. 38,000) during acute alveolar injury. The present study may suggest that while alveolar type H cells proliferate markedly, transcription of alveolar type ll cell gene was inhibited by an unknown mechanism such as DNA methylation induced by NNNMU. Such an inhibition of transcriptional activity is thought to be associated with the decreased secretory activity of alveolar type ll cells, which may lead to pulmonary atelectasis and edema during the acute alveolar injury.

Fatality of accidents on curved roads where rollover accidents are likely to take place was higher than that on straight roads. We ought to investigate factors affecting injury severity of occupant in a vehicle rollover accident. From January 2011 to December 2013, we collected data about rollover motor vehicle crash accident. We surveyed occupant's injury, vehicle type, safety devices, type of rollover accident and the number of turn in accident. Of the 132 subjects, 56.1% were males, 50.8% were drivers, 48.5% fastened seat belt, and air bag deployed in 12.1%. Among injuries sustained head, chest and abdomen were major sites of severe injury(Abbreviated injury scale>2). Seat belt use, rollover type, and the number of 1/4 turn were found to have significant positive correlations with Injury Severity Score. The regression analysis herein found significance in safety belt use and the number of 1/4 turn. Seat belt use was a significant factor affecting injury severe of occupant in rollover accident.

Soccer is type of sport that carries a high risk of injury. Injury is not only cause in the unlucky soccer carrier and also team performance as well as financial effects can be worse since soccer is a team-based game. The duration of recovery from a soccer injury typically relies on its type and severity. Therefore, we conduct this research in order to predict the probability of players injury type using machine learning technologies in this paper. Furthermore, we compare different machine learning models to find the best fit model. This paper utilizes various supervised classification machine learning models, including Decision Tree, Random Forest, K-Nearest Neighbors (KNN), and Naive Bayes. Moreover, based on our finding the KNN and Decision models achieved the highest accuracy rates at 70%, surpassing other models. The Random Forest model followed closely with an accuracy score of 62%. Among the evaluated models, the Naive Bayes model demonstrated the lowest accuracy at 56%. We gathered information about 54 professional soccer players who are playing in the top five European leagues based on their career history.

Objective:This study aims to devise industrial injury prevention measures by analyzing industrial injury characteristics including the status of industrial injuries, source of industrial injury and accident type in order to prevent aging workers' industrial injuries that account for more than half in the workplaces in agriculture. Background: Continuous migration from farm to city takes place among young people in rural areas in Korea, a traditionally agricultural country due to rapid industrialization and economic development. The aging rate in rural areas in 2013 was 37.3%, about three times higher than the total aging rate of 12.2% in Korea. According to industrial injury statistics of the Ministry of Employment and Labor, the number of industrial injuries in agriculture shows an uptrend and the industrial injuries of aging workers account for more than 50% each year. Method: Of the 2,970 industrial injury cases occurred in the workplaces in agriculture for five years during 2008 and 2012 offered by a national agency related to health and safety, this study analyzed 1,767 industrial injury cases of aging workers. Results: As a result of an analysis on aging workers' industrial injuries by company size in agriculture, 89.8% of the total number of industrial injuries were analyzed to occur in small scale company. According to aging workers' industrial injuries by source of industrial injury and accident type, the outdoor floor and a fall were analyzed to be the highest at 16.5% and 26.1%, respectively. Conclusion: This study analyzed aging workers' industrial injuries by company size, age, job duration, accident severity, gender, nationality, the source of industrial injury and accident type in order to identify industrial injury characteristics in agriculture. Application: The identification of industrial injury characteristics of aging workers in agriculture is judged to be helpful to devising effective measures to prevent industrial injuries.

Other than gunshot injuries, sacral penetrating injuries with a foreign body exiting to the other side are extremely rare. We encountered a case of sacral injury in which a long metallic pipe penetrated from the anus into the lower back of a patient. Since the pelvis contains various organs, management of a penetrating injury requires multidisciplinary treatment involving several medical specialties. Due to the infrequency of this type of injury, there are no definitive guidelines for effective management. We described our experience surgically treating a sacral penetrating injury and conducted a literature review. On this basis, we suggest a surgical strategy for treating this type of injury.
