There is increasing need for network connecting personal computers(PC) together. Thus Local Area Network(LAN) emerged, which was designed to allow multiple computers to access and share multiple files and programs and expensive peripheral devices and to communicate with each user. We built PC-LAN in our department that consisted of 1) hardware-9 sets of personal computers(IBM compatible 80386 DX, 1 set:80286 AT, 8sets) and cables and network interface cards (Ethernet compatible, 16bits) that connected PC and peripheral devices 2) software - network operating system and database management system. We managed this network for 6 months. The benefits of PC-LAN were 1) multiuser (share multiple files and programs, peripheral devices) 2) real time data processing 3) excellent expandibility and flexibility, compatibility, easy connectivity 4) single cable for networking ) rapid data transmission 6) simple and easy installation and management 7) using conventional PC's software running under DOS(Disk Operating System) without transformation 8) low networking cost. In conclusion, PC-LAN provides an easier and more effective way to manage multiuser database system needed at hospital departments instead of more expensive and complex network of minicomputer or mainframe.

PURPOSE: This study examined patients with facial bone fracture visiting Pusan National University Dental Hospital to understand the trends, and to enhance appropriate care and treatment for patients with facial bone fracture. METHODS: We investigated 531 patients presenting with facial bone fracture in Yangsan and 802 patients in Busan from January 2010 to December 2013. We divided the patients by year, month, gender, age, site, and cause to compare with historic data and other studies. RESULTS: The gender ratio was 3.58:1 in Yangsan and 4.31:1 in Busan. Patients aged in their 20s had the highest number of facial bone fractures in both Yangsan and Busan. The most frequent fracture site was the mandible, and the most frequent cause was slip down in both Yangsan and Busan. CONCLUSION: The investigation and comparison of patients with facial bone fracture who visited Pusan National University Hospital located at Yangsan and Busan from 2010 to 2013 found a difference in the total number of patients at each hospital, but the trends were not significantly different.

Purpose:
This study aimed to conduct a systematic literature review and meta-analysis of the exercise intervention effects for the prevention of musculoskeletal injuries in military personnel.
Methods:
Among studies that included military personnel as participants, we identified randomized controlled trials (RCTs) and cluster-RCT studies that used exercise interventions as a method for injury prevention. Exercise encompassed all types of physical activity, and the effect size was determined by the ratio of injuries between groups.Literature searches were conducted with search terms modified to ensure common inclusion of keywords such as “Soldier,” “Injury prevention,” and “Exercise.” For the analysis of potential factors, variables selected for group differentiation included gender, risk of bias, exercise volume, injury location, exercise type, and study design.
Results:
Among a total of 8,598 search results, 10 papers were finally confirmed. The meta-analysis of all 10 papers showed that there was no statistically significant injury prevention effect, and significant heterogeneity was observed among the studies (incidence rate ratio, 0.82; 95% confidence interval, 0.62–1.09, I2 =83%). Subgroup analysisrevealed a significant 44% reduction in injuries in studies where exercise volume for injury prevention was relatively high. However, no significant injury prevention effects were observed in other potential factors between groups.
Conclusion
The results of this study suggest that the effectiveness of injury prevention exercises in military settings was not statistically significant. However, through the analysis of potential factors, it was confirmed that increasing the time spent on injury prevention exercises may have a preventive effect on injuries.

BACKGROUND: This study was designed to evaluate the efficacy and safety of midazolam premedication administered by a jet-injector in pediatric patients. METHODS: Children undergoing outpatient surgery were randomized into three groups: intravenous induction with thiopental sodium (control group, n = 20), oral midazolam premedication (PO-med group, n = 20) or midazolam premedication using a jet-injector (Jet-med group, n = 20). In the PO-med and Jet-med group patients, anesthetic induction was performed by sevoflurane inhalation and an intravenous catheter (IVC) was inserted after the children had been anesthetized by sevoflurane inhalation. For the control group patients, an IVC was placed in the preoperative holding area. Agitation scores were recorded in the preoperative holding area and recovery room. Anesthesia times and the views of the medical staff concerning the technique benefits were also noted. Patients and parents were interviewed on the following day. RESULTS: Maximum agitation scores in the preoperative holding area and during separation with parents were significantly lower in the PO-med and Jet-med groups. The induction time was significantly longer in the PO-med and Jet-med groups. No statistically significant differences were found for the recovery characteristics. Though interviews with patients and parents produced similar results for patients in each group, the medical staff satisfaction levels were significantly higher for patients in the PO-med and Jet-med groups. CONCLUSIONS: The findings of this study suggest that the application of the jet-injector for midazolam premedication may be clinically useful in children who do not have an IVC. The use of the jet-injector could be a substitute for the oral route for midazolam administration.

A 36-year-old woman with an unremarkable medical history presented for laparoscopic cholecystectomy. Routine preoperative assessment of the patient's airway revealed normal jaw opening. Upon induction of anesthesia, her jaw locked in a nearly closed position. X-ray and MRI of the temporomandibular joints that were taken postoperatively showed normal findings except for the steeper posterior angles of the articular eminences. During the next induction of anesthesia, intubation was readily accomplished by opening the mandible with a forward pulling of the chin.

Benign prostate hyperplasia (BPH) is a common disease in old-age males, accounting for approximately 77% of morbidity within the age range of 40 to 70 years. It has been shown that morbidity increases with social graying. Quisqualis indica linn (QI) has been used to treat inflammation, stomach pain, and digestion problems. In this study, we evaluated the symptom-regulating effects of QI extract on a testosterone-induced BPH rat model. After inducing BPH in rats using testosterone propionate (TP) injection, we assessed basal intraurethral pressure (IUP) and increments of IUP elicited by electrical field stimulation (5 V, 5, 10, or 20 Hz) or phenylephrine (Phe) (0.01, 0.03, 0.1 mg/kg IV). To induce BPH, 8-week-old rats were subjected to a daily subcutaneous TP (3 mg/kg) injection for 4 weeks. Finasteride (Fina) (10 mg/kg PO) was administered to the rats in the first treatment, while QI (150 mg/kg PO) was administered to those in the second group. Blood pressure was measured together with IUP, after which low urinary tract (LUT), ventral prostate (VP), testicle, and corpus spongiosum were isolated and weighed. Basal IUPs for the Fina- and QI-treated groups were 87.6 and 86.8%, respectively.LUT and VP organ weights in the QI group were lower than those in the Fina group. However, the QI group showed significantly reduced electrical stimulated or Phe-induced IUP increment compared to the Fina and BPH groups. These results proved that QI can be beneficial for BPH symptoms by inhibiting 5α-reductase and consequently decreasing prostate and releasing urinary pressure.

A Dieulafoy lesion is a relatively rare, but potentially life threatening cause of gastrointestinal bleeding, which accounts for only 1~2% of acute cases. The most common site is the stomach and most extragastric lesions are frequently found in the duodenum followed by the esophagus, the colon, and rectum. However, jejunum and ileum are extremely rare. I report on a case of a 38-year-old female who underwent laparoscopic resection of a bleeding Dieulafoy's lesion in the jejunum following intraoperative endoscopy.
