본 조사는 대한건축학회의 일부조사비보조로 이루어진 것으로 폭발사고는 금년 11월11일 밤9시15분 전북이리역 구내에서 다이너마이트와 전기뇌관등 약 40t의 고성능 폭발물을 가득 실은 화차가 폭발,고성능 대형폭탄이 터진 곳과 같은 충격과 폭파력으로 이리시 전역을 거의 강타 1,000명이 넘는 사상자를 냈으며 9,500 여채의 가옥이 부서지는 초유의 대참사를 빚었으며 이로 인해 토목,건축물에도 많은 피해를 주었다. 필자들은 폭발후 약 일주일후에 대한건축학회 회장임의 협조로 피해 현장을 조사할 기회를 얻었다. 조사후 아직 얼마되지 않아 자료를 정리할 수 없는 현상이므로 상세한 보고는 후일에 하는것으로 하고 이번에는 이리시내의 각종 건물의 피해의 개략을 소개하고자 한다.

Purpose 68Ga-labeled 1,4,7,10-tetraazacyclododecane-N,N′,N″,N‴-tetraacetic acid-D-Phe1-Tyr3-octreotide (68Ga-DOTATOC) istaken up by activated macrophages, which accumulate in active inflammatory lesions. The purpose of this study was toinvestigate the feasibility of 68Ga-DOTATOC PET/CT for assessment of vulnerable plaque, by evaluating correlation betweenaortic uptake of 68Ga-DOTATOC and cardiovascular risk factors. Methods Fifty patients with neuroendocrine tumors who underwent 68Ga-DOTATOC PET/CT were retrospectively enrolled. The uptakes in the thoracic aorta were measured by two methods: multi-sample region-of-interest (ROI) method and singlevolume-of-interest (VOI) method. TBRmax-avg, TBRmean-avg, TBRmax-VOI, and TBRmean-VOI were defined by maximum and meantarget-to-background ratio (TBR) from the multi-sample ROI method and the single VOI method, respectively. Results Framinghamrisk score (FRS) exhibited significant correlations with TBRmax-avg and TBRmean-avg, aswell as TBRmax-VOI(r = 0.3389–0.4593, P < 0.05 for all). TBRmax-avg and TBRmax-VOI were significantly higher in high FRS group than in low FRSgroup (1.48 ± 0.21 vs. 1.70 ± 0.17, P < 0.001 for TBRmax-avg and 1.90 ± 0.33 vs. 2.25 ± 0.36, P = 0.002 for TBRmax-VOI). TBRexhibited high correlations between the two measuring methods (r = 0.9684, P < 0.001 for TBRmean-avg and TBRmean-VOI and r =0.8681, P < 0.001 for TBRmax-avg and TBRmax-VOI). Conclusions 68Ga-DOTATOC uptake in the thoracic aorta exhibited a significant correlation with cardiovascular risk factors,which suggests the feasibility of 68Ga-DOTATOC PET for vulnerable plaque imaging, with a simple measurement of the singleVOI method that is comparable to the multi-sample ROI-based approach.
An Update on [18F]Fluoride PET Imaging for Atherosclerotic Disease

Atherosclerosis is the leading cause of life-threatening morbidity and mortality, as the rupture of atherosclerotic plaques leads to critical atherothrombotic events such as myocardial infarction and ischemic stroke, which are the 2 most common causes of death worldwide. Vascular calcification is a complicated pathological process involved in atherosclerosis, and microcalcifications are presumed to increase the likelihood of plaque rupture. Despite many efforts to develop novel non-invasive diagnostic modalities, diagnostic techniques are still limited, especially before symptomatic presentation. From this point of view, vulnerable plaques are a direct target of atherosclerosis imaging. Anatomic imaging modalities have the limitation of only visualizing macroscopic structural changes, which occurs in later stages of disease, while molecular imaging modalities are able to detect microscopic processes and microcalcifications, which occur early in the disease process. Na[18F]-fluoride positron emission tomography/computed tomography could allow the early detection of plaque instability, which is deemed to be a primary goal in the prevention of cardiac or brain ischemic events, by quantifying the microcalcifications within vulnerable plaques and evaluating the atherosclerotic disease burden.

Planar scintigraphy using Tc-99mpertechnetate is useful for snapshot evaluation of hot thyroid nodules, which are pathologicallyfollicular adenoma and seldom, if ever, malignant. The autonomy of the hot nodules has been demonstrated by the presence ofthyroid-stimulating hormone-dependent extra-nodular thyroid tissue besides the hot nodules. Here, we present two cases of hotthyroid nodules in patients who underwent quantitative single-photon emission computed tomography/computed tomography(SPECT/CT). In addition to the nodules, contralateral normal thyroid parenchyma was evaluated based on standardized uptakevalues. One patient had a traditional follicular adenoma suppressing other thyroid tissue, whereas the other patient seemed to havea nodule erupting from underlying hyperfunctioning, not suppressed, thyroid tissue. This novel approach using quantitativeSPECT/CT unveils a new pathology of hot thyroid nodule that does not suppress, but coincides with hyperfunctioning thyroidtissue.

본 연구에서는 철근콘크리트 기둥에서 주근의 좌굴성장을 수치 해석법으로 조사하는 것을 목적으로 콘크리트의 모델과 철근과 콘크리트의 경계면에서의 상호 힘의 전달을 나타내는 수치 해석모델을 제안하였다. 본 연구에서 제안된 수치 해석법에 의해 콘크리트의 변형도 연화 및 철근의 좌굴을 고려한 해석이 가능한 것으로 판단되었으며 또한 취급된 해석예에서는 주근의 좌굴은 띠철근의 간격 및 주근의 배근위치에 크게 영향을 받는다는 것을 알 수 있다. The study summarized in this paper is concerned with the buckling of longitudinal bars in reinforced concrete columns with numerical analysis method. The objectives of this study are (1) to investigate the stress transfer mechanism between concrete and reinforcement and (2) to propose a modeling equation. The results give an acceptable agreement between the proposed modeling equation and published computer packages as follows; (1) the proposed equation is a possible of strain softening of concrete and buckling of reinforcement. (2) the buckling of longitudinal bar is mainly influenced by spacing of hoop and location of the bar
