건물군 인벤토리가 고려된 다차원법을 활용한 홍수피해액 산정
이석호,이석호,김길호,김병식 한국방재학회 2018 한국방재학회논문집 Vol.18 No.7
As a result of recent climate change, flood damage originating from local floods and typhoons has become more frequent, costing many lives and damaging property. Especially in city centers, a large amount of damage can occur due to inundation caused by river flooding. In this study, flood damage area was calculated using the Flo-2D flood inundation model, and the estimated flood damage was calculated using multi-dimensional flood damage analysis. In general, the flood damage rate can be calculated using the area ratio according to the land use in the affected administrative district. However, in this study the flood damage rate was calculated using the flood damage rate proposed in the multi-dimensional flood damage analysis. The estimated flood damage as a function of return period were estimated using the estimated flood damage rate. The flood damage rate estimated using the area ratio was estimated to be at least 51% with a maximum 75% lower than the flood damage rate estimated using the building group, and the total damage was underestimated when the area ratio was used. Therefore, it is necessary to estimate damages using building inventories presented in the multidimensional law for residential and industrial areas. 최근 기후변화로 인해 국지성 집중호우 및 태풍으로 제내지 침수로 인한 홍수피해가 빈번하게 발생하고 있으며, 많은 인명피해와 재산피해가 발생하고 있다. 특히 도심지에서 하천의 범람으로 인한 침수로 많은 피해액이 발생하게 된다. 따라서 본 연구에서는 도심을 흐르는 도시하천인 원주천유역을 대상으로 홍수범람모형인 Flo-2D모형을 이용하여 홍수피해면적을 산정하였으며 다차원법을 이용한 피해액 산정방법을 통하여 빈도별 예상홍수피해액을 산정하였다. 일반적으로 행정구역상 토지이용에 따른 면적비를 이용하여 침수편입률을 산정하나 본 연구에서는 다차원법에서 제시하는 침수편입률 산정방법을 이용하여 산정하였다. 산정 결과 면적비를 이용한 편입률이 건물군을 이용한 편입률 보다 최소 51%, 최대 75% 낮게 산정되었으며 면적비를 이용하였을 때 과소 산정되는 것으로 나타났다. 따라서 다차원법을 이용한 피해액 분석시 주거, 산업의 경우 다차원법에서 제시되고 있는 건물군을 이용하여 피해액을 산정하는 것이 필요하다고 판단된다.

Facioscapulohumeral muscular dystrophy (FSHD), the third most common inherited muscular dystrophy, is an autosomal dominant disease characterized by progressive weakness and wasting of the facial, shoulder-girdle, upper arm, foot extensor, and pelvic girdle muscles. FSHD is caused by contraction of the polymorphic D4Z4 repeat in the subtelomere of chromosome 4q. However, there has been no report of genetically confirmed FSHD in Korea. We report a patient with FSHD who was found to have a deletion of D4Z4 repeat on chromosome 4q35.

Analyses of SGTR Accident With Mihama Unit Experience
이석호,김갑,김효정,은영수,Lee, S.H.,Kim, K.,Kim, H.J.,Eun, Y.S. Korean Nuclear Society 1994 Nuclear Engineering and Technology Vol.26 No.1
A SGTR accident postulated at Kori unit 1 is simulated with Mihama unit experience, which occurred on February 1991, to evaluate the capability of plant to cope with the transient. The system design and plant conditions of Kori Unit 1 are much similar with those of Mihama Unit 2. Therefore, special concern has been given to evaluate the sequence and the resulting consequence of the postulated SGTR accident at the Kori unit 1 An analysis is peformed as realistically as possible, with following the EOP of Kori unit 1. The result indicates that the leak through tube break terminates within about forty minutes, and the Kori unit 1 may be sufficient to cope with SGTR accident with same type of sequence. However, the reconsideration may be required for the design of Kori unit 1 which disconnects non-safety AC power from off-site power on SI signal generation. It may be pointed out that the content of EOP for SGTR accident is not enough to require operator's proper judgements. An analysis of SGTR accident tested in the LSTF which simulated the SGTR accident at the Mihama Unit 2 is peformed using the RELAP5/MOD3. The results indicates that the code yields in general good agreement with the test, except the break flowrate at the early stage of the event.
