Status epilepticus (SE) has been described as a rare manifestation of hepatic encephalopathy. Massive bleeding and subsequent anemia may precipitate atherothrombotic cerebral infarction. Stroke is one of the possible causes of SE. A 69-year-o1d male with decompensated alcoholic liver cirrhosis presented with altered mental state and generalized convulsive SE after massive hematemesis due to varix bleeding. The hemoglobin level was 5.5 mg/dL and blood ammonia level was more than twice the normal level. The seizure was resolved after prompt and aggressive treatment for SE. The blood ammonia level was normalized after treatment for hepatic encephalopathy, but the patient' s mental state was not recovered. Brain MRI revealed multiple ischemic lesions in the both cerebral hemisphere. We present the patient as SE after acute ischemic stroke associated with anemia in hepatic encephalopathy.

간경화 환자에서 조증으로 발현한 메트로니다졸 뇌병증

Although mania is commonly associated with bipolar disorder, it can have many etiologies. Secondary mania results from pharmacological, metabolic, or neurologic causes. Mania as adverse effects of antibiotics such as metronidazole is infrequent. We report a 51-year-old man with liver cirrhosis but no past history of psychiatric illness, who developed mania after receiving metronidazole. Brain magnetic resonance imaging (MRI) showed characteristic lesions which indicated metronidazole-induced encephalopathy. After stopping metronidazole, his manic symptom disappeared. Neuroimaging examination suggests that our patient’s manic symptom was ascribable to damage to the rostral brainstem monoaminergic nuclei and its projections to the frontal-subcortical circuit components.

A Case of Psychogenic Paraplegia Documented During Sleep by Video Monitoring

오형근,이경석,박형국,양광익 대한수면연구학회 2009 Journal of sleep medicine Vol.6 No.1

Psychogenic paraplegia is an uncommon conversion disorder characterized by nonorganic loss of motor function precipitated by some type of traumatic event. A 60-year-old man was referred from neurosurgery department with the chief complaint of paraplegia. One year ago he was involved in a motor vehicle accident. Whole spine magnetic resonance imaging (MRI) and electrophysiological study couldn’t explain the organic cause of paraplegia. We decided to observe him during his sleep as we suspected a psychogenic cause for the symptoms. Irregular, non-stereotyped and involuntary leg movements were documented during sleep by video monitoring, and he was diagnosed as psychogenic paraplegia. In conclusion, if a psychogenic paraplegia is suspected, video monitoring during sleep could be recommended as a differentiation tool from neurological disorder.

북한의 소방대에 관한 연구

오형근 북한연구소 2023 북한학보 Vol.48 No.2

Fires are caused by various causes and cause serious damage to human life, which also acts as a factor of social anxiety. Countries around the world have firefighting teams composed of personnel, equipment, and fire extinguishing water to minimize the occurrence of fires and the damage caused by them. North Korea has set up fire teams in safety ministries set up in cities and counties across the country to handle fire fighting and fire prevention activities. The Ministry of Security, which directs and supervises the fire brigade, is a sub-executive agency of the Ministry of Social Safety, which is responsible for monitoring and controlling residents throughout North Korea. However, safety from fire is prioritized by residents' perception of fire, and the fire brigade's smooth fire fighting activities are attached to institutions that have factors of conflict with residents, even though they can only be effective if they have close relationships with residents. These organizational limitations of the North Korean fire brigade can serve as a major factor that makes it difficult to integrate fire in the future, such as inter-Korean fire cooperation, win-win period, and further unification stage, along with doubts about whether the North's fire brigade is functioning normally. This study is a basic study that examines the operation status of firefighting forces, mainly by fire brigade installed in the Ministry of Safety in North Korea, and through this, we would like to present policy focus for fire development and cooperation between the two Koreas. 화재는 다양한 원인으로 발생하여 인간 생활에 심각한 피해를 주는것으로 사회불안의 요인으로도 작용한다. 세계 각국은 화재 발생과 그로 인한 피해를 최소화하기 위해 인력과 장비, 소화 용수 등으로 구성된 소방대를 두고 있다. 북한은 전국의 시와 군 단위에 설치되어 있는 안전부에 소방대를 두어 화재진압과 화재 예방 활동을 담당하도록 하고 있다. 소방대를 지휘하고 감독하는 안전부는 북한 전역에서 주민을 감시하고 통제를 담당하는 사회안전성의 하부 실행기관이다. 그러나 화재로부터의 안전은 불을 다루는 주민들의 인식이 우선하는 것으로 소방대의 원활한 소방활동은 주민들과의 긴밀한 관계가 있어야 만이 효과를 발휘할 수 있음에도 주민과의 갈등 요인을 가지고 있는 기관에 부속된 것이다. 이러한 북한 소방대의 조직편제 상 한계는 북한의 소방대가 정상적인 기능을 하고 있는지에 대한 의구심과 함께 향후 남북한 소방협력이나 상생기, 나아가 통일단계에서 소방 통합을 어렵게 하는 주요 요인으로 작용할 수 있다. 본 연구는 북한의 안전부에 설치된 소방대를 위주로 소방력의 운영실태를 살피는 기초연구이며, 이를 통해 남북한 소방 발전과 협력을 위한 정책적 착안점을 제시하고자 한다.

Population Genetic Structure of the Bumblebee, Bombus ignitus (Hymenoptera: Apidae), Based on Mitochondrial COI Gene and Nuclear Ribosomal ITS2 Sequences

오형근,윤형주,이주영,박정선,김익수 한국잠사학회 2013 International Journal of Industrial Entomology Vol.27 No.1

The bumblebee, Bombus ignitus (Hymenoptera: Apidae), is a valuable natural resource that is widely utilized for greenhouse pollination in South Korea. Understanding the magnitude of genetic diversity and geographic relationships is of fundamental importance for long term preservation and utilization. As a first step, we sequenced a partial COI gene of mitochondrial DNA (mtDNA) corresponding to the “DNA barcode” region and the complete internal transcribed spacer 2 (ITS2) of nuclear ribosomal DNA from 88 individuals collected in nine South Korean localities. The complete ITS2 sequences were longest among known insects, ranging in size from 2,034 bp ~ 2,052 bp, harboring two duplicated 112-bp long repeats. The 658-bp long mtDNA sequences provided only six haplotypes with a maximum sequence divergence of 0.61% (4 bp), whereas the ITS sequences provided 84 sequence types with a maximum sequence divergence of 1.02% (21 sites). The combination of the current COI data with those of published data suggest that the B. ignitus in South Korea and China are genetically a large group, but those in Japan can be roughly separated into another group. Overall, a very high per generation migration ratio, a very low level of genetic fixation, and no discernable hierarchical population were found to exist among the South Korean populations of B. ignitus , which suggests panmixia. This finding is consistent with our understanding of the dispersal capability of the species.

The purpose of this study is to analyze e-Sports keywords utilizing the big data analytical technique, and provide the basic data required for establishing e-Sports policies. To achieve this purpose of research, text mining, sentiment analysis, and CONCOR analysis were performed. The search volume analysis results for e-Sports keywords showed the maximum search volume as of October 2021. This period is the time of the 2021 LoL World Championships, and the success of the events has been shown to affect e-Sports interest. For keyword frequency analysis results, sports, games, Korea, competitions, athletes, league of legends, venues, battlegrounds, zenji, competitions were shown the highest frequency and derived as key keywords. As a result of sentiment analysis, the positive rate (75.81%) was found to be very high, and that was classified as good, recommendation, new, growth, best, wanted, etc. The negative rate was 24.19%, and negative keywords such as difficult, esoteric, caution, bad, etc. were classified. As a result of the CONCOR analysis, ‘National e-Sports League’, ‘e-Sports Professional Training’, ‘Asian Games’ and ‘Amateur e-Sports Events’ were formed as a group. These results are believed to reflect interests of demand for national and international e-Sports events and fostering the specialized workforce through the professional training courses.

탈북자의 주거지 소방안전인식에 대한 연구

오형근 한국방재학회 2019 한국방재학회논문집 Vol.19 No.3

정부는 탈북자들이 입국할 경우 정착지원제도를 통해 주거지를 알선하고 있으며, 탈북자들은 주로 일자리 확보가 용이한 도시지역의 아파트를 선호하고 있다. 그러나 아파트는 고층이면서 열에너지와 가연성 내장재를 사용하고 있어 화재위험이 잠재해 있으나 이에 대한 소방안전 교육과 훈련이 이루어지지 않고 있어 화재시 인적·물적 피해의 위험에 노출되어 있다. 이에 본 연구는 아파트에서 거주하는 탈북자들을 대상으로 설문을 실시하여 소방안전에 대한 인식을 도출하고 이를 바탕으로 이들의 거주지 소방안전 향상방안을 제시하고자 한다. When defectors enter the country, they arrange their residence through a settlement support system. Defectors prefer apartments in urban areas where job hunting is easy. However, the apartments are high-rises and use thermal energy and flammable interior material; therefore, there is a risk of fire, but fire safety training is not conducted, and there is the risk for human and material damage in the case of fire. The purpose of this study is to suggest ways to improve the fire safety of residents based on the results of a questionnaire on defectors living in apartments.
