This study focused on the effects of median type on drivers' subjective sense of speed and the changes in this sense by driver age. Participants were 61 drivers: 20 young (aged 20-39 years), 19 middle-aged (40-59 years), and 22 older drivers (60+ years). The participants watched each of two driving scenarios, showing either a guardrail-equipped or a concrete median. The participants were asked to push a button when they perceived speeds of 60 km/h, 80 km/h, or 100 km/h. All drivers perceived higher speeds in the guardrail condition than in the concrete condition. Perceived speeds increased with driver age in both guardrail and concrete conditions. These results mean median type affects drivers' subjective sense of speed even as driver age increases, and that drivers' subjective sense of speed tends to increase with age.

From January 2 to December 30, 2017, out of 691 children diagnosed with dermatophytoses infection, 179 children had infections caused by Trichophyton among the total 13,093 patients who visited the Dermatology department. According to a survey, the patients included 317 adolescents, 203 elementary school age children, and 171 infants. In seasonal variation, the diagnosis was higher in summer (195 cases, 28%) and winter (191, 28%) and comparatively lower in spring (165, 24%) and autumn (140, 20%). The infection among the patients was caused by, from maximum to minimum, T. pedis (351, 51%), T. corporis (91, 13%), and T. unguinum (77, 11%). In all age groups, the highest number of patients were infected with T. pedis. After T. pedis, in descending order, the infection was caused by T. corporis, T. unguinum, T. manus and Tinea capitis in the infants and elementary school age children and by T. corporis, T. unguinum and T. cruris in adolescents. Among infections caused by Trichophyton, T. rubrum was the highest isolated causative agent. This data analysis confirmed the distribution of dermatophytoses and the different species according to paediatric age and will aid the study of paediatric dermatomycosis through continuous research.

This study has been done to understand the relationship between age norms and negative perception on older workers, and to find out moderating effect of recognition of employment welfare services in those relationships. And the purpose of this study is to suggest alternative ways to improve pessimistic perception on older workers, which is basal ageism. For this purpose, the survey has been conducted with 630 participants, who were 20 years old and over and lived in 15 different provinces. The collected data has been analysed by using SPSS Win 18.0. The results as followed: first, there were significant differences of negative perception on older workers among provinces(metropolitan areas, small towns, and rural areas); second, age norms significantly influenced on pessimistic perception on older workers; third, moderating effect of recognition of employment welfare services has been verified. These results suggest that it is necessary to promote people to take a flexible attitude toward older adults using media broadcasting and promotion of employment welfare services. Public and private cooperation should be needed to change people's negative perception on older workers. Lastly, programs, which are appropriated and tailored in specific provinces, improving awareness of older workers should be required.

Purpose : AOM is the most common bacterial URI in children. The bacteriology and antibiotic Tx of AOM in children has been studied in many countries. But, there is few study of causative pathogens and antibiotic Tx of AOM in our country. In this aspect, we performed prospective clinical study to confirm the causative pathogens and assess the clinical responses of cefprozil in AOM patients. Methods : Thirty three AOM patients enrolled in this study. Tympanocentesis for isolation of causative pathogens were performed before Tx of cefprozil. The study patients received cefprozil with dose of 15 mg/kg/bid.po/day for 10-12 days, and initially assessed the clinical response at 4-5 days after receiving cefprozil and finally at the end visit. In vitro susceptibility tests of cefprozil to isolated pathogens were done by disc diffusion method, and in vitro susceptibility tests of cefaclor and cefixime to isolated pathogens were simultaneously performed. Results : Bacterial pathogens[S. pneumoniae(10), H. influenzae(5), S. aureus(2), M. catarrhalis(1) and Group A stretococcus(1)] were isolated from 19 patients. Clinically, all patients had history of abrupt high fever except one. Tympanic perforation was dominant in pathogens isolated cases, and otalgia was significantly developed in non-pathogens isolated cases. The ages of pathogens isolated cases were usually below 2 years. Eighty four point nine percent of the patients including two cases with isolation of intermediate resistant S. pneumoniae were clinically improved. Antimicrobial in vitro activity to S. pneumoniae of cefprozil were superior than that of cefacor and cefixime. Conclusion : We confirm that bacteria has the causative role in about 60% cases, and S. pneumoniae is the most common pathogen. Clinically, there were some differences in symptoms, signs and ages between pathogens isolated and non-pathogens isolated cases. The clinical responses of cefprozil in our patients revealed similar outcomes to other countries. And we reconfirm that cefprozil may be clinically effective in cases of AOM due to intermediate resistant S. pneumoniae.

Purpose To assess the prevalence of incidentally detected lumbar spondylolysis in children. Materials and Methods We retrospectively reviewed the data of 809 patients under the age of 11 years (mean age, 7.0 ± 2.7 years; boys:girls = 479:330) who underwent abdominal and pelvic CT between March 2014 and December 2018. We recorded the presence, level, and laterality (unilateral or bilateral) of spondylolysis. Patients were divided into two groups based on the presence of spondylolysis: the spondylolysis (SP) and non-SP groups. Results In total, 21 cases of spondylolysis were detected in 20 patients (20/809, 2.5%). The mean age of the SP group was higher than that of the non-SP group (7.8 ± 1.8 vs. 6.9 ± 2.7 years, p > 0.05). The prevalence of spondylolysis in boys was higher than that in girls (15/479 [3.1%] vs. 5/330 [1.5%], p > 0.05). The prevalence of spondylolysis in school-age children (6-10 year olds) was higher than that in preschool-age children (0-5 year olds) (17/538 [3.2%] vs. 3/271 [1.1%], p > 0.05). L5 was the most common level of spondylolysis (76.2%); one 8-year-old boy had two-level spondylolysis. One case of isthmic spondylolisthesis was detected in a 10-year-old boy (1/809, 0.1%). There were 11 unilateral spondylolysis cases (11/21, 52.4%). Conclusion In our study, the prevalence of spondylolysis in children under the age of 11 was 2.5%. The prevalence was higher in boys than in girls and in school-age than in preschool-age children, despite the lack of any statistically significant differences.
