WiBro(휴대 인터넷)는 언제 어디서나 고속으로 무선 인터넷 접속이 가능한 서비스를 위한 기술이다. 노트북을 비롯한 휴대가 간편한 PDA, 스마트폰으로 사람이 보행 또는 차량 주행 중에서도 끊김없이(seamless) 무선 인터넷 서비스가 가능하다. 휴대 인터넷 서비스는 무선랜과 3G 이동통신이 제공하는 데이터 통신을 융합하고, 두 서비스의 단점을 보완하는 형태의 무선 통신 서비스라고 할 수 있다. 이동성과 고속 무선 통신이 가능한 서비스에서 가장 중요한 기술 요소 중 하나가 보안이다. 본 논문은 안전한 서비스를 제공하기 위하여 WiBro 무선 네트워크에서의 UICC 기반의 EAP-AKA 인증 프로토콜을 적용한 사용자 인증 메커니즘의 상세한 프로토콜을 제안한다. 따라서 EAP-AKA 기반의 무선 네트워크 인증을 통하여 WiBro 무선 네트워크에서 뿐만 아니라 USIM 기반의 WCMDA 등의 이기종 무선 네트워크와의 연동(interworking)에서도 보다 효율적으로 적용할 수 있다. WiBro(Portable Internet Service) is service being capable to provide a high data rate wireless internet access with Personal Subscriber Station under the stationary or mobile environment, anytime and any where. It will fill the gap between very high data rate wireless local area networks and very high mobility cellular systems. The security is an important point of WiBro providing high data and mobile wireless services. This paper proposes user authentication mechanism of WiBro wireless networks applied EAP-AKA authentication protocol. As a result of Wireless authentication based on EAP-AKA, this mechanism is capable to be used in WiBro-WLAN-3GPP interworking scenario as well as the WiBro authentication mechanism.

The purpose of this study is to investigate the dietary life status according to smart device use among university students. In 2015, data was collected during a 3 month survey of the eating behaviors, lifestyles, eating habits, and use of smart devices of 550 university students, as well as their dependency on smartphones. Ultimately, 520 subjects (94.5% analysis rate) were divided into three groups based on their daily use time of smart device: low-use group (<4.7 hours, n=173), medium-use group (${\geq}4.7hours$ and <6.4 hours, n=174), and high-use group (${\geq}6.4hours$, n=173). The more frequent use groups showed a higher level of dependency on the smartphone. Breakfast was found to be the most commonly skipped meal; and the high-use group showed a higher response of irregular meals than low-use group. In assessment of eating habits, the subjects with less smart device usage ate more regularly and at fixed times, did not overeat, drank milk everyday, and did not consume processed food as often. To sum up, more irregularity of meal and undesirable eating habits were found among university students with higher use of smart devices. These results suggest that a control of smart device usage would lead to a more desirable dietary life in university students.

Purpose: To report an immunocompetent patient with more than 1-year survival after treatment with voriconazole, despite invasive paranasal sinus aspergillosis involving the orbital apex. Case summary: A 74-year-old woman with only preexisting hypertension visited our clinic complaining of pain and immovable left eye that occurred approximately 4 days prior. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a sphenoid sinusitis with suspicious lesion involving the orbital apex of the left eye. A biopsy by functional endoscopic sphenoid surgery (FESS) was performed through the sphenoid sinus, which enabled us to diagnose aspergillosis. The patient had esotropia, ophthalmoplegia, positive RAPD, and ptosis in the left eye. On follow-up, a new MRI showed acute to subacute stage infarction at the left occipital lobe. After the patient was treated with intravenous voriconazole, ptosis, and ophthalmoplegia improved. At the 13-month follow-up, she was alive with no disease recurrence. Conclusions: Invasive aspergillosis of orbit and cerebrum in healthy patients is a rare clinical entity. In case of central nervous system involvement, the survival outcome is poor with high mortality; however, good results can be obtained by treatment with voriconazole.

Purpose: To suggest a diagnostic criteria of pattern visual evoked potential (VEP) in adult monocular amblyopic patients in comparison to normal subjects.<br /> Methods: The medical records of patients’ military service certificates from January 2000 to December 2011 were reviewed. The parameters of pattern VEP were analyzed by comparing monocular amblyopic patients with normal controls.<br /> Results: This study included 47 monocular amblyopia and 39 normal control patients. All parameters of pattern VEP were statistically significantly different between monocular amblyopic eyes and normal eyes. The cut-off values for diagnosis of adult amblyopia using receiver operating characteristic (ROC) curve were 113.50 msec (P100 latency), 1.05 (ratio of P100 latency), 8.50 msec (interocular difference of P100 latency), and 5.25 μV (interocular difference of P100 amplitude). Cut-off value sensitivities were generally low: (51.1%, 70.2%, 53.2%, and 31.9%, respectively).<br /> Conclusions: The value of pattern VEP parameters had limitations due to low sensitivity and could be considered as ancillary diagnostic criteria when diagnosing amblyopia. <br /> J Korean Ophthalmol Soc 2013;54(12):1875-1881

N/A Background/Aims: The a-glucosidase inhibitors, acarbose and miglitol have been successfully used to control postprandial hyperglycemia in diabetics. They probably work by slowing down carbohydrate digestion and absorption, but the nature of their effect on the enzymes and the level of specific action have not been studied. This animal experiment is aimed to evaluate the effects of acarbose on intestinal disaccharidase activity and to explore the gene expression of the intestinal sucrase after intake of acarbose. Methods: Fifty normal adult rats were given acarbose orally in doses of 20 mg/ kg for 5 days and then sacrificed at the first(Group A), fourth(Group B), seventh (Group C), and 14th day(Group D) after withdrawal of acarbose. Intestines of 50 rats were obtained and divided into 3 equal length. Mucosal homogenates were prepared for measurement of specific activities of disaccharidases. Total RNA was extracted for determination of the amount of sucrase mRNA by Northern and slot hybridization. Results: The specific activities of sucrase were significantly reduced in mucosal homogenates of proximal segment of small intestines in Groups A, B, and C as compared witb those in control group(p0.05). But there were no changes in rniddle and distal segments in Groups A, B, and C. And decreased specific activities of sucrase in proximal segment in Groups A, B, and C were completely recovered in Group D. The amount of sucrase mRNA was correlated with the specific activities of sucrase in the proximal segment of small intestine in groups A, B, and C(r=0.67, p-- 0.05). Conclusions: Acarbose reversibly inhibits sucrase activities only in the proximal segment of small intestine. Genetic regulation determining inhibition of a-glucosidase by acarbose is considered to occur at the transcription level. (Korean J Gastroenterol 1995;27:300 - 308)
