주기교대눈떨림와 주기교대주시편위는 이상안구 운동에서도 흔히 관찰되지 않는다. 이런 안구운동은 뇌교와 소뇌에 병변이 있을 때 나타난다고 보고되고 있다. 50세 남자 환자가 과음을 하고 난 이후 심하게 구토를 하여 입원하였다. 다음날 아침에 의식이 없었으며 주기교대눈떨림과 주기교대주시편위가 관찰되었다. 뇌자기공명영상에서는 뇌교나 소뇌에 병변없는 교뇌외수초용해증에 합당한 소견을 보였다. 저자는 아마도 교뇌외수초용해증이 소뇌와 전정신경핵의 경로중에 GABA 시스템에 이상이 발생하여 주기교대눈떨림과 주기교대 주시편위가 나타났을 것으로 추정한다. Background; Periodic alternating gaze deviation(PAGD) and periodic alternating nystagmus(PAN) are rare forms of abnormal eye movement. Multiple lesions in the cerebellum and brainstem have been reported with PAN and PAGD. Case Report; A 50-year-old man presented with severe vomiting after binge drinking. The next morning he. became vegetative state and showed PAGD and PAN. Brain MRI showed findings compatible with extrapontine myelinolysis(EPM) without any brainstem or cerebellar lesions. Conclusions; We postulate that the disturbed GABAnernic system in the pathway from the cerebellum to vestibular nuclei caused probably by EPM developed PAGD and PAN.

예전 인구에 근거하여 연구된 논문들은 편두통이 뇌졸중의 위험성을 높일 수 있다는 보고를 하였으며, 전조증상을 동반한 편두통은 중추신경계와 연관된 병인론적 과정을 통하여 뇌졸중과의 관련성이 있다는 보고가 있다. 그러나, 편두통성 뇌졸중의 병태생리는 아직 정확히 밝혀지지 않았다. 편두통의 발생 원인에서 혈관성 이론은 편두통을 혈관수축으로 발생하는 전조증상과 함께 대뇌 조절 장애로 발생한다는 이론으로 뇌허혈증상은 일으킬 수 있다. 전조증상을 동반한 편두통성 뇌경색은 허혈성 뇌졸중의 드문 원인이며, 또한 편두통과 허혈성 뇌졸중사이의 관련성은 아직 논란으로 남아 있다. 우리는 혈관경련 수축으로 나타날 수 있는 전조성 편두통과 관련된 뇌경색에서의 가역적 후뇌 동맥 폐색 1례를 보고한다. Several previous population-based studies reported an increase risk of stroke in association with migraine. Migraine with aura increased stroke risk with pathogenetic process in the central nervous system. However, the pathologic mechanism of migrainous infarction remains elusive. The vasogenic theory ascribes migraine to cerebral dysregulation with aura resulting from vasoconstriction. Migrainous infarction with aura is a rare cause of cerebral ischemic stroke. Also, the relationship between migraine and ischemic stroke remains controversial. We report a case of cerebral infarction associated with migraine with aura that shows reversible arterial narrowing which might be caused by vasospasm.
익명성 관련 측도에 기반한 데이터 프라이버시 확보 알고리즘에 관한 연구

익명화 기법은 마이크로 데이터에서 프라이버시를 보호하기 위해 제안된 방법 중의 하나이다. 원본 데이터로부터 그룹화를 기반으로 프라이버시를 확보하고자 하는 익명화 기법은 k-익명성(k-anonymity) 개념을 효시로 하여 ℓ-다양성(ℓ-diversity), t-밀접성(t-closeness) 등의 개념이 차례로 제안되면서 발전된 모습을 보여주었다. 프라이버시 측도 관점에서 각각의 익명성 관련 개념들이 상호 보완적인 관계에 놓여 있으나, 데이터의 유용성과 익명성 개념들을 복합적으로 고려한 실질적인 익명화 알고리즘 개발에 관한 연구는 아직까지 미진한 상태이다. 본 논문에서는 먼저 기존에 발표된 익명성 개념들에 기반한 익명성 측도들과 정확성 관련 측도들에 대하여 비교 분석한다. 또한, k-익명성을 만족하는 데이터로부터 블록 합병 방법에 의하여 ℓ-다양성을 확보하는 알고리즘을 새롭게 제안한다. Technique based on the notions of anonymity is one of several ways to achieve the goal of privacy and it transforms the original data into the micro data by some group based methods. The first notion of group based method is k-anonymity, and it is enhanced by the notions of ℓ-diversity and t-closeness. Since there is the natural tradeoff between privacy and data utility, the development of practical anonymization algorithms is not a simple work and there is still no noticeable algorithm which achieves some combined anonymity conditions. In this paper, we provides a comparative analysis of previous anonymity and accuracy measures. Moreover we propose an algorithm to achieve ℓ-diversity by the block merging method from a micro-data achieving k-anonymity.

Korean is a complex subtle language. Many Korean users upload personal stories to the Internet, but Korean language in the field of natural language processing is not developed due to the relatively low number of users. In this paper, we investigated the possibility of using Opinion Mining as a Post-Occupancy Evaluation method. The focus of this study is on how we can translate customer - provided housing experiences into useful information in data analysis. We analyzed the articles posted in the online community using the Python package called ‘KoNLPy’. In this process, I felt the difficulty of Korean language processing. In Korean natural language processing packages, it is possible to break up into an eulogy unit, but it is not possible to grasp the meaning of the correct word or to classify it into a proper morpheme. The construction industry in Korea is very conservative and it will not be easy to apply Opinion Mining to the practical stage. However, if the vocabulary network related to the residence experience is established and the skill level of observing the tendency of the people through the social network analysis is increased, the utilization of the natural language processing in the construction industry is expected to be very high.

Background: Sleep duration is associated with hearing loss, especially presbycusis, which is the most common type of hearing loss; however, there is limited evidence regarding this association among the Korean population. We aimed to determine the relationship between sleep duration and high-frequency hearing loss in Korean adults aged ≥40 years.Methods: We examined 5,547 Korean adults aged ≥40 years who completed audiometric tests and questionnaires regarding sleep duration during the 2010–2012 cycle of the Korea National Health and Nutrition Examination Sur-vey. Mild presbycusis was defined as >25 decibels (dB) and <40 dB, whereas moderate-to-severe presbycusis was defined as >40 dB pure tone averages at high frequencies (3,000, 4,000, and 6,000 Hz) for both ears. Additionally, the sleep duration was divided into quartiles. Odds ratios and 95% confidence intervals were estimated using mul-tivariable logistic regression after adjusting for covariates.Results: The prevalence of presbycusis in South Korean adults was 62.1%, of which 61.4% showed moderate to se-vere presbycusis. The incidence of moderate-to-severe, but not mild, presbycusis showed a significant positive cor-relation with sleep duration.Conclusion: Our findings suggest that sleep duration is associated with the prevalence of presbycusis.
