OBJECTIVES: The purpose of this study was to estimate the incidence of injuries and to identify their causes by classifying injuries according to various categories including age, sex, mechanism of injury, body parts injured, and place of injury. METHODS: This study used data from the Korea National Hospital Discharge In-depth Injury Survey (KNHDIS) from 2004 to 2016. The KNHDIS is conducted annually by the Korea Centers for Disease Control and Prevention, and its survey population includes all hospitalized patients discharged from medical institutions that have 100 or more beds, such as hospitals, general hospitals, and secondary community health centers. The number of injured cases is weighted and estimated using the mid-year estimated population of each year. RESULTS: The injury discharge rate steadily increased since 2004 (1,505 per 100,000 population in 2004, 2,007 per 100,000 population in 2016) and most injuries were unintentional (annual average of 94.7%). On average, during the 13-year study period, the injury rate for males was 1.5 times as high as for females. The 2 main causes of injury were consistently traffic accidents and falls. Notably, the rate of injuries resulting from falls rose by 1.7-fold from 463 to 792 per 100,000 people, and exceeded the rate of traffic accidents in 2016. CONCLUSIONS: The incidence of injuries steadily increased after the survey was first conducted, whereas mortality resulting from injuries mostly remained unchanged. This suggests that effective strategies and interventions should be reinforced to reduce unintentional injuries.

The effects of nacl concentration, temperatura, light and growth regulator(GA3, kinetin) on the tuber germination of s. maritimus were investigated. The germination percentage increased with decreasing nacl, showing salt tolerance through time, and with increasing temperature untile 20~30oC light / dark (12/12 hr) of optimal temperature. The multiplication of nacl and temperature on germination percentage and velocity, increased significantly in higher temperature than lower temperature in saline. The germination percentage showed high value in dark condition than in light condition which is the charracteristics of underground organ. and ga3 act as germination stimulator to overcome the inhibitory effect of nacl. The effect of ga3 showed significant differances on tubers of s. maritimus of germination but that of kinetin had a litter sffects on germination. Factors of nacl and temperature interacted significantly and the effects of nacl on germination percentage and velocity depended on temperature condition.

Background: The adoption of a western lifestyle in Asian countries may result in a higher prevalence of diverticulosis. Approximately 20% of all patients with diverticula develop acute diverticulitis. The aims of the present study were to evaluate the clinical feature of acute diverticulitis and analyze the risk factors of complications. Methods: The medical records of 228 patients who were hospitalized due to acute diverticulitis between January 2008 and June 2014 were reviewed, retrospectively. The patients baseline characteristics, clinical symptoms, treatment and complications were assessed. Results: Mean age of the patients was 54.76 ± 17.53 years and male to female ratio was 138 to 90 . Recurrent attack was noted in 47 patient (20.6%). The most common symptom was abdominal pain(92.1%), fever (50%) and bloating(46.5%). Right colon involvement was more common(74.1%). Complication was noted in 54 patients(23.7%). The most common complication was abscess formation(9.6%) and perforation occurred in 7%. Abscess formation was treated by percutaneous drainage catheter insertion and colon perforation was treated by surgery. During the follow up period, 29 patient(12.7%) experienced recurrent attack of diverticulitis. Previous history of diverticulitis is not related with complication occurrence. Patients older than 60 years more frequently developed complications during hospitalization ( P=0.047, odds ratio : 1.857). Especillay, the frequency of perforation was high (P=0.02, odds ratio : 6.22). The risk factors for complication include older age than sixty, shock and fever. Conclusion: The most common symptom of acute diverticulitis is abdominal pain, fever and bloating. The right sided diverticulitis is dominant. Complications rate was 23.7%. The risk factor of complication include older age than sixty ,shock and fever. Therefore, we should pay particular attention to the patients who have these risk factors about occurrence of complications.

Purpose : This study was undertaken in order to find out the actual correlation between skipping breakfast of school-aged children and their mothers. Method : The subjects of this study were 724 children and their mothers. The subjects were selected from two schools out of six offices of education in Busan between December 1 and December 20, 2002. The collected data was analyzed through real numbers, percentage, mean and standard deviation, cross tabulation, $\chi^2$-test, t-test, F-test, Scheffe-test and Pearson correlation coefficient using the SPSSWIN 11.0. Results : The results of this study are summarized as follows. 48.6% of children skipped breakfast while 54.7% of mothers skipped breakfast. The case that both children and mothers skipped breakfast were 37.1%. The correlation of children's skipping breakfast and their mothers characteristics was statistically significant(r=.288(p<0.001). There was relationship between the life styles of children and their mothers, but there was no relationship between life styles and the frequency of skipping breakfast. Conclusion : children are affected by or depend on their mothers eating habits and other tendencies in daily life.
