Objectives : This study aimed to investigate the difference of brain activities in viewing a common emotional situation according to perspective-taking. Methods : Using fMRI, brain activities were measured while performing the task viewing a common emotional situation on either self-perspective or third-person perspective in fourteen healthy men. The relatively activated brain areas on each perspective were investigated, then the relationship between the activated brain regions and the scores of self report about some emotion or empathic ability were explored. Results : The relatively activated brain areas on self-perspective were bilateral paracentral lobule(BA 5), right postcentral gyrus(BA 3), right precentral gyrus(BA 4), left superior temporal gyrus(BA 22), left medial frontal gyrus(BA 6), whereas on third-person perspective right inferior frontal gyrus(BA 47), left caudate body and tail, right superior temporal gyrus(BA 38), right medial frontal gyrus(BA 8) were activated. The relative activity of left superior temporal gyrus on self-perspective was positively correlated with the score of Beck Depression Inventory. Conclusion : This study demonstrated that the activated brain region according to perspective-taking were different while viewing a common emotional situation. The depressive feeling would have an influence on the brain activity related to perspective-taking.

스마트 TV가 최근 IoT 생태계의 중심으로 떠오름에 따라 그 중요성은 갈수록 높아지고 있다. 스마트 TV 내 취약점이 발생하는 경우 도청, 도촬로 인한 사생활 침해 및 개인정보 유출의 측면 뿐만 아니라 금전적 피해까지 발생할 가능성이 있다. 본 논문에서는 스마트 TV 취약점 분석의 완전성을 높이기 위해 STRIDE 위협 모델링을 통해 위협을 체계적으로 식별하고 공격 대상에 대한 특성을 파악하였다. 또한 Attack Tree와 취약점 점검리스트를 제작하고 실제 취약점 분석을 통하여 점검리스트의 효과성을 검증하여 안전한 스마트 TV 사용 환경을 위한 보안 요구사항을 도출하였다. As smart TVs have recently emerged as the center of the IoT ecosystem, their importance is increasing. If a vulnerability occurs within a smart TV, there is a possibility that it will cause financial damage, not just in terms of privacy invasion and personal information leakage due to sniffing and theft. Therefore, in this paper, to enhance the completeness of smart TV vulnerability analysis, STRIDE threat classification are used to systematically identify threats. In addition, through the manufacture of the Attack Tree and the actual vulnerability analysis, the effectiveness of the checklist was verified and security requirements were derived for the safe smart TV use environment.

Purpose: To report a case of cancer-associated retinopathy developed in a patient with small cell lung cancer, which is a kind of paraneoplastic syndrome. Methods: A 78-year-old woman presented complaining of decreased visual acuity and visual field that had developed about 15 days previously. She was diagnosed with small cell lung cancer 1.5 years ago and underwent 3 cycles of chemotherapy. At presentation, the best-corrected visual acuity was hand motion in both eyes and there was no afferent pupillary defect. Slit-lamp biomicroscopic examination revealed no specific abnormality in the anterior segment of either eye, and intraocular pressure was normal. Posterior segment examination demonstrated remarkable arteriolar narrowing in both eyes, but there was little doubt about the presence of an optic nerve lesion such as optic disc edema or pallor. Results: Fluorescein angiography and brain magnetic resonance imaging (MRI) revealed no significant abnormalities. However, electroretinograms (ERG) demonstrated marked reduction in the a and b waves. Visual evoked response was delayed for the latency period. She was treated with systemic steroid, after which her visual acuity gradually improved.

Purpose: To quantitatively compare the role of posterior vitreous detachment in macular edema associated with branch retinal vein occlusion (BRVO) using OCT. Methods: A retrospective study of 36 eyes with BRVO-associated macular edema was carried out from November 2003 to February 2005. There was posterior vitreous detachment (PVD) in 23 eyes [PVD (+) group], and vitreoretinal attachment on the fovea in 31 eyes [PVD (-) group]. PVD was detected with an indirect ophthalmoscope or 90D lens. The foveal thicknesses of the two groups were measured and compared. Results: The mean foveal thicknesses of the PVD (-) and PVD (+) groups were 398.0±217.2 ?m and 233.6±80.6 ?m, respectively (p=0.000, Mann-Whitney test). The mean BCVA (log MAR) was 0.77±0.52 in the PVD (-) group and 0.40±0.37 in the PVD (+) group (p=0.002, Mann-Whitney test). Conclusions: The extent of macular edema associated with BRVO was significantly less in the PVD(+) group and BCVA was significantly better in the PVD (+) group as well.

Purpose: To report a male infant with bilateral Duane`s retraction syndrome treated with bilateral horizontal transpositions of vertical recti to the lateral rectus muscle. Methods: An 8-month-old boy showed bilateral Duane`s retraction syndrome with esotropia of 45PD, severe limitation of abduction (-4 and -3.5 in each eye) and mild globe retraction in both eyes. It was assumed that he inherited the condition from his father through an autosomal dominant pattern. His father showed esotropia of 25PD with -4 limitation of abduction in the left eye and a left head-turn of 10。. He also had +2 globe retraction, +1 upshoot and +2 downshoot in adduction of the left eye. Transposition of two vertical recti to the lateral rectus muscle was performed in both eyes of the boy. Results: Nine months after surgery, the boy had achieved a microesotropia of 6PD in primary gaze with stereopsis of 3000 seconds of arc and considerable improvement in abduction (-2, -1.5 in each eye). The amount of correction of esodeviation was 39PD. This favorable state was maintained at follow-up 3.5 years after surgery. Conclusions: An 8-month-old boy who had esotropia of 45PD caused by bilateral Duane`s retraction syndrome, underwent bilateral horizontal transpositions of vertical recti to the lateral rectus muscle. He achieved a microesotropia of 6PD in primary gaze and considerable improvement of abduction with only mild eyeball retraction.

Purpose: To compare the effect of intravitreal triamcinolone injection with and without bevacizumab for diabetic macular edema. Methods: Of 69 patients (69 eyes) diagnosed with diabetic macular edema without any history of other intraocular disease or intraocular operation, 45 eyes (45 patients) were injected with intravitreal triamcinolone (4 mg) and the remaining eyes (24 patients) were injected with triamcinolone (2 mg) and bevacizumab (1.25 mg). The visual acuity and central macular thickness of treated eyes from both groups was measured using OCT, and these measurements were compared between the two groups. Results: There were no statistical differences between the two groups with respect to baseline data. Central macular thickness (CMT) was reduced in both groups, and BCVA improved in both groups. No significant differences were detected in changes in CMT or BCVA between the two groups. Conclusions: Intravitreal injection of triamcinolone had a beneficial effect on DME in terms of CMT reduction and BCVA improvement. Addition of three consecutive intravitreal bevacizumab injections, however, did not show any significant addictive effect during the follow-up period. J Korean Ophthalmol Soc 49(8):1269-1274, 2008
