In this study, the relationship between the awareness of blood program and the blood donation experience has been studied to know whether they corelate or not. The awareness of blood program was divided into 4 areas of knowledge and measured: the eligibilityt of blood donation, knowledge about blood, blood donation program, and general facts about blood donation. The experience of blood donation was divided into 3 groups: the registered donor, the non-registered donor, and the nondonor. The result in this study shows that the awareness of blood program is related with 3 factors, such as the eligibility of blood donation, blood donation program, and general facts about blnation. The difference in this case is significant at 0.05 level. However the knowledge about the blood is not corelated with blood donation experience, but only with sex(P<0.05). These results suggest that stable blood supply should be realized by securing new donors and by estsablishing of fdonor registration system. This is realized by the stir up the level of awareness and interest of blood program through strengthening public relations.

PURPOSE: This study examined to explore factors influencing on employment stress of university students. METHODS: The data were collected by structured questionnaires to students who agreed to be the subjects of this study. And 230 cases were finally analyzed. T-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression were conducted for data analysis using SPSS/WIN 18.0. RESULTS: Significant differences revealed in age, department of major, residental type and school year on employment stress by general characteristics. Also, employment stress showed negative correlation with self-esteem, and satisfaction in major. Self-esteem and satisfaction in major, department of major were confirmed as a factors influencing on employment stress and accounted for 36% of the variance. CONCLUSION: Further studies that discover factors influencing on employment stress of university students are needed, and also practical programs are necessary to decrease employment stress of university students.

Access to the craniofacial skeleton and skull base requires osteotomies. An adequate exposure of neoplasms occupying the skull base and the oral cavity and oropharynx, especially retromolar trigone, is very important for precise tumor ablation. The demonstration by Tessier of the capacity for large segments of bone to survive removal and replacement has enabled skull base tumor surgery to grow into a subspeciality. Through the refined craniofacial exposure osteotomies, the surgery is safer, the operation shorter, and the result better both oncologically and reconstructively. We experienced 24 cases of exposure osteotomies consisting of 12 cases transzygomatic approaches, 1 case tranglabellar osteotomy, 1 case lateral transmaxillary approach, 1 case Le Fort II & midline splitting, and 9 cases mandibulotomy. There was no significant complication except a local wound infection in transzygomatic approach and one case of minimal malocclusion after parasymphyseal mandibulotomy. The orthotopic bone graft and the rigid fixation enables the postoperative morbidity to decrease. It seems that the previously inaccessible craniofacial tumors can be treated through the various exposure osteotomies.

Fibrofolliculoma is a benign follicular neoplasm which usually occurs in multiple and rarely solitarily. We have found only seven cases of previous reports of solitary fibrofolliculomas worldwide and only two in Korean literature. Herein we report on a 40-year-old female patient with a solitary flesh-colored bean sized mass on the scalp which histopathologically proved to be a fibrofolliculoma.

STUDY OBJECTIVES: To identify the value of symptoms in head trauma patients with alert mental status requiring a head CT scan. METHODS: A retrospective study was performed at an emergency center over 8 months period. Patients(age > or = 7) were enrolled if they presented with a Glasgow Coma Scale score of 15 and underwent head CT after head trauma. The symptoms and signs were recorded in the entry forms prior to head CT The symptoms found in the patients with normal CT were compared with those in abnormal CT showing intracranial injuries. RESULTS: Among the 168 patients, traumatic intracranial abnormality was identified in 34(20.2%) by CT. Skull fracture was idendified in 8(4.8%) in normal CT, 17(10.1%) in abnormal CT group by simple X-ray and CT. In the normal CT group without skull fracture, 65(52.0%) had headache, 61(48.8%) had loss of consciousness( LOC), 43(34.4%) had vomiting, 24(19.2%) had nausea, 7(5.6%) had dizziness. In the abnormal CT group without skull fracture, 14(77.8%) had heacache, 9(50.0%) had LOC, 9(50.0%) had vomiting, 2(11.1%) had nausea, 2(11.1%) had dizziness. The patients with headache were significantly more common in the abnormal CT group. CONCLUSION: A head CT is required in alert head trauma patients with any symptoms and signs of intracranial injuries, especially with headache.

PURPOSE: Sexual differences in the incidence and crystalline composition of urinary stones in humans are well-known, but it is unclear why men have a higher incidence of calcium oxalate stones than women. We investigated the effects of male sex hormones on stone formation using an ethylene glycol (EG) - induced urolithiasis model in rats. MATERIALS AND METHODS: Adult male Sprague-Dawley rats were divided into 4 groups, each containing 10 rats. One group of rats was left untreated and served as control. The other 3 groups were fed a 1% ethylene glycol (EG) lithogenic diet for 4 weeks. Among these, one group was non-castrated, one group was castrated and one group was non-castrated and given finasteride orally. Serum testosterone, creatinine, electrolytes, 24-hour urine levels of oxalate and citrate, and creatinine clearance were measured. The crystal deposits were examined by light and polarizing microscopes. RESULTS: Testosterone promoted calcium oxalate stone formation in EG - treated rats. Finasteride administration significantly decreased urinary oxalate excretion and calcium oxalate deposition, compared with controls. Urinary citrate was significantly decreased in EG-treated rats, but was not influenced by castration or administration of finasteride. There were no significant differences in serum concentrations of creatinine, sodium, or potassium among the control and experimental groups. CONCLUSIONS: Our data suggest that testosterone promotes calcium oxalate stone formation, and that dihydrotestosterone may be partially responsible for the exaggerated hyperoxaluria in EG-treated rats. Additionally, male sex hormones have a lesser influence on urinary citrate than oxalate.

In view of the potential of replicase protein as a diagnostic reagent for human caliciviruses (HuCVs), we have cloned and over-expressed this gene from the Snow Mountain-like Korean strains in Escherichia coli as a fusion protein with glutathione S-transferase (GST, and described the preliminary antigenic characterization of the recombinant products. Each 470bp fragment corresponding to highly conserved region of RNA-dependent RNA polymerase was generated by RT-PCR from stools of two diarrheal children, cloned in pMOSBlue T-vector, and subcloned between the EcoRI and SalI restriction sites of pGEX-47-3, a GST gene fusion vector, yielding pGCVpol. This construct expressed a Snow Mountain-like HuCV replicate under the control of the IPTG-inducible pac promoter. An extract prepared by sonication of the E. coli cell inclusion bodies bearing pGCVpol products was purified and analyzed by SDS-PAGE. After Coomassie blue staining, it was shown that the recombinant replicase migrated on the gels with an approximate molecular mass of 46.5 kDa, that was subsequently cleaved into a 26 kDa GST fragment and a 20.5 kDa replicase protein upon digestion with thrombin protease. The replicase was recognized on immunoblotting with the sera from symptomatic children with the HuCV-associated diarrhea but not by asymptomatic sera from adults. The results presented the first biological activity of individually expressed HuCV replicase subunit and provided important reagents for diagnosis of HuCV infection.
