Purpose: The prevalence of problematic internet usage among college students is a cause for concern. There is a lack of study examining influences of cognitive protecting or buffering factors on internet addiction among college students. The purpose of this study was to examine influences of depression, ego-resilience, and active stress coping on internet addiction tendency (IAT) among college students. Methods: A cross-sectional, descriptive design was used. Data were collected between October and December 2013. A convenience sample of 244 students completed self-report questionnaires consisting of Ego-resiliency Scale, Ways of Coping Checklist, Center for Epidemiologic Studies-Depression, and Self-report Scale for Internet Use. Stepwise multiple regression analysis was performed for data analysis. Results: We found that higher levels of depression were associated with higher levels of IAT. However, an inverse association was found between active stress coping and IAT. Students who mainly used the internet for chatting showed lower levels of IAT than those who used the internet for games or blogs. These factors explained 15.1% of the variance in IAT of college students. Conclusion: The study results suggest that stress coping strategies and depression are important factors for evaluation when developing intervention programs targeting college students with problematic internet use.

This case report describes the effectiveness of cervical corrective exercises in a patient with cervical radiculopathy (CR) who experienced radicular pain, upper limb paresis, and limited functional activity. A 39-year-old male with cervical radiculopathy performed the cervical corrective exercises for reducing pain. Pain intensity, cervical posture, and active range of motion of cervical intersegmental spine motion were measured baseline, after 4 weeks, and after 8 weeks with self-reported questionnaire and radiographs. After 8 weeks of intervention, the patient demonstrated alleviated radicular symptoms, improved neck posture and active range of flexion and extension of the cervical intersegmental spine. Especially in the angle between the cervical vertebra 6 and 7, the angle was changed from $-4.69^{\circ}$ to $3.30^{\circ}$ during resting position after intervention. The present case indicates that the cervical corrective exercises might be a possible treatment to effectively reduce radicular symptoms, improve neck posture, and active cervical intersegmental motion for patient with CR.

Vedolizumab (VDZ) has been approved for the treatment of inflammatory bowel diseases (IBDs) in patients aged ≥18 years. We report a case of a pediatric patient with Crohn disease (CD) who was successfully treated with VDZ. A 16-year-old female developed severe active pulmonary tuberculosis (TB) during treatment with infliximab (IFX). IFX was stopped, and TB treatment was started. After a 6-month regimen of standard TB medication, her pulmonary TB was cured; however, gastrointestinal symptoms developed. Due to the concern of the patient and parents regarding TB reactivation on restarting treatment with IFX, VDZ was started off-label. After the second dose of VDZ, the patient was in clinical remission and her remission was continuously sustained. Ileocolonoscopy at 1-year after VDZ initiation revealed endoscopic healing. Therapeutic drug monitoring conducted during VDZ treatment showed negative antibodies to VDZ. No serious adverse events occurred during the VDZ treatment. This is the first case report in Korea demonstrating the safe and effective use of VDZ treatment in a pediatric CD patient. In cases that require recommencement of treatment with biologics after recovery of active pulmonary TB caused by anti-tumor necrosis factor agents, VDZ may be a good option even in pediatric IBD.

Objectives: Active participation of poultry breeder in surveillance system of Avian Influenza (AI) is very important. Therefore this study was conducted to present basis data for active report of AI that is affected by media's coverage in poultry breeder. Methods: Subjects were 88 persons, 28 who were poultry breeder at epidemic area of AI and 60 who were general person at non-epidemic area. Data were collected by the trained investigator from Jul. 1 to Aug. 31, 2008. Respondents were interviewed by means of a structured questionnaire. Results: The third-person effect among perceptions of influence in media's report on the AI was higher in breeder (32.1%) than in non-breeder (10.0%). However, Confidence to media report on the AI was lower in breeder than in non-breeder. Intention to report of the AI was 71.4% in breeder respectively, was 90.0% in non-breeder. There was statistically significant lower in breeder than non-breeder. The cause of avoidance of report was 'economic damage' for 87.5%, which acocounted for the majority of cases. Confidence to media report on the AI were positively correlated with concern on the AI and perception on seriousness of the AI, but negatively correlated with the third-person effect. Conclusions: These results showed that intention to report of the AI of breeder was susceptible to influenced by the third person effect and confidence in media's report on the AI. Therefore we should give a special attention to increase active report of poultry breeder during epidemic period of AI which is consideration of reasonable strategy of media's coverage, including mind and emotion state of poultry breeder.

Excessive oral and maxillofacial bleeding causes upper airway obstruction, bronchotracheal & gastric aspiration and hypovolemic shock. Therefore, the rapid & correct bleeding control is very important for life-saving in the medical emergency room. In spite of the bleeding control methods of the wound suture & direct pressure, the postoperative bleeding can be occurred, because of the presence of various bleeding disorders & postoperative delayed wound infections. The proper care of bleeding disorders & wound infections are very important for the control of the delayed postoperative rebleeding. In spite of these methods, active oral bleeding can be presented by the other causes of head injury. A rare but particularly dangerous sort of bleeding that may have an especial importance to the patient with severe basal skull fracture that damage large vessels and even the cavernous sinus. The occurrence of profuse nasal or oropharyngeal bleeding may arise from damage to the anterior and posterior ethmoidal vessels, but when mixed with brain tissue it is evidence of mortal damage. In this condition, rapid entire oropharyngeal packing is essential for the control of active oral bleeding. This is a case report of rapid rational bleeding control method by much amount of wet gauze packings, in a 44-years-old male patient with active oropharyngeal bleeding by basal skull fractures.

The most common local cause of active gingival bleeding is the vessel engorgement and erosion by severe inflammation. Abnormal gingival bleeding is also associated with the systemic disturbances. Hemorrhagic disorders in which abnormal gingival bleeding is encountered include the following: vascular abnormalities (vitamin C deficiency or allergy), platelet disorders, hypoprothrombinemia (vitamin K deficiency resulting from liver disease), and other coagulation defects (hemophilia, leukemia). There are many conventional methods for gingival bleeding control, such as, direct pressure, electrocoagulation, direct suture, drainage, application of hemostatic agents and crushing and packing. If the active continuous gingival bleeding is not stopped in spite of the application of all conventional bleeding control methods, the life of patient is threatened owing to upper airway obstruction, syncope, vomiting and hypovolemic shock. Therefore, the rapid and correct hemostatic method is very important in the emergency dental care. This is a case report of active gingival bleeding care via dental crown removal and emergency primary endodontic drainage as a last method in liver cirrhosis patient with advanced periodontitis.
