In order to evaluate the nature, severity and characteristics of psychotic symptoms in mania, we investigated 22 manic patients with psychotic features and also 22 manic patients without psychotic features and 22 schizophrenics as control group. All of these patients were assessed with SADS(Schedule for Affective Disorders and Schizophrenia) at admission and two months later. The results were as follows ; 1) At admission, manic patients with psychotic features and schizophrenics showed similar scores on the following items ; ie delusion of reference, delusion of being controlled, mind being read, thought broadcasting and the severity of delusions. Two months later, the total severity of delusions-hallucinations were significantly greater in schizophrenics than in manic patients with psychotic features(p<0.05). 2) Manic patients with psychotic features showed significantly higher scores on the items of loss of sleep, usually energetic, increased activity, grandiosity, speeded thinking, and poor judgement than manic patients without psychotic features at admission and two months later(p<0.05). 3) Flight of ideas was significantly greater in the manic patients with psychotic features than in schizophrenics(p<0.001). Incoherence, loosening of associations, illogical thinking, and neologisms occured in manic patients with psychotic features as frequently as in schizophrenics. Poverty of content of speech was significantly greater in schizophrenics than in manic patients with psychotic features(p<0.001). 4) In manic patients with psychotic features, treatment responses were significantly better than in schizophrenics(p<0.001), but poorer than in manic patients without psychotic features(p<0.01). 5) Manic patients have more alcoholics in their first-degree relatives than schizophrenic group. These results suggest that the manic with psychotic features is a distinct diagnostic entity from schizophrenia, and a more severe form of mania.

이 연구는 최근 지자체 차원에서 빠르게 확산되고 있는 복지기술이 어떻게 생산되고 확산되어 상용화되는지를 개발자의 경험을 통해 분석하고 구조화함으로써 복지기술 개발에 대한 정책적, 실천적 함의를 찾고자 하는 것이다. 이를 위해 복지기술 관련 기업 개발자에 대한 포커스 그룹 인터뷰(FGI)를 통해 질적 자료를 수집하였다. 분석 결과, 총 46개의 개념이 확인되었으며, 1) 복지기술 사업 참여배경과 제품개발, 2) 복지기술 제품개발 유형과 사업화 과정 등 2개의 주요 범주가 도출되었다. 주요 결과를 토대로 복지기술 기업의 특수성과 복지기술 생산과정에서의 민관협력의 실제, 정부의 구체적인 역할 등을 확인하였으며, 복지기술 개발에서 데이터 활용에 대한 정부의 합리적 가이드라인과 규칙 제정이 필요함을 제안하였다.

Potential Rise Characteristics of a Grounding Grid Subjected to Lightning Currents
최종혁,이재석 한국조명.전기설비학회 2016 조명·전기설비학회논문지 Vol.30 No.6
This paper presents the results of an investigation into the factors that affect the impulse response of a grounding grid under the passage of lightning currents. We carried out simulations of potential rise of a 10m×10m square grounding grid comprising 4 meshes buried in the soil of about 140Ω․m resistivity. The potential rise profiles of the grounding grid stressed by lightning currents were computed by EMTP software. The dissipation current and the potential rise for the 0.25/100μs current wave were significantly concentrated around the current injection point. The impulse coefficient for a corner-positioned lightning strike point showed a doubling of the impulse coefficient compared to the corresponding central strike point of the grounding grid.
