N/A Scintigraphic measurement of gastric emptying time has been reported to be influenced by the variation in depth of radionuclide within the stomach. In order to determine the effect of tissue attenuation in the measurement of gastric emptying time, 15 gastric emptying studies were performed with Tc-99m labeled egg sandwiches. Single anterior detector method overestimated the T1/2 by an average of 13% than geometric mean method and the range of overestimation was wide (from -13% to +32%). Therefore, to evaluate the gastric empthying time accurately, methods of attenuation correction are needed.

본 연구는 교회의 작은도서관의 현황과 특성을 파악하고 운영 활성화 방안을 제안하기 위함이다. 교회도서관 현황은 매우 열악한 수준이었으며, 교회도서관 운영 활성화 요인 분석 결과, 보유 장서수가 운영활성화 수준에 가장 큰 영향을 미치고 있었다. 규모, 인력, 이용현황에 대한 군집 분석 결과, 극소수의 도서관만이 우수한 수준을 보였다. 따라서 교회도서관의 운영 활성화 방안으로 첫째, 교회도서관의 운영 목적과 목표를 뚜렷이 정하고, 안정된 운영예산과 운영을 책임질 수 있는 전담 인력과 직원을 확보해야 한다. 둘째, 교회시설을 활용하여 도서관의 특성에 맞는 프로그램 개발, 독서의 질을 높일 수 있는 양질의 지식콘텐츠를 서비스해야 한다. 셋째, 도서관 협력 네트워크를 활용한 타도서관과의 상호대차, 순회사서 시스템을 활용할 수 있어야 하고, 적극적인 마케팅 활동으로 지역주민들이나 교인들에게 홍보해야 한다. 또한 목회자와 책임운영자는 헌신과 봉사의 마음으로 지역사회에 서비스해야한다. In order to explore the exact current status and features of small church libraries and suggest implications on how to facilitate their operations, this study has analyzed general conditions of their current operations. Firstly, all aspects of facilities, books, and people of small church libraries, the three elements of libraries, have turned out to be under poor conditions compared to small regular libraries. Secondly, out of all factors that encourage the use of church libraries, the number of retained books in libraries appears to be most influential. Thirdly, it is shown in the results of an analysis on each category group that most church libraries are under poor conditions and only few of them are excellent in terms of the current status of their sizes, labor forces, and users. Based upon these findings, this study suggests implications on facilitating church library operations as follows. First of all, it is highly crucial to have full-time workers and professional staffs who can set aims or purposes of church libraries and be in charge of stable management of budget and library operations. Secondly, it is also important to develop programs suitable for each library’s features and knowledge contents to improve the quality of reading experience. Thirdly, through utilizing library cooperative networks, interlibrary loan or librarian rotation systems should be available. Also, through proactive marketing activities, libraries should be promoted to local communities or church members. Lastly, the most significant part for facilitating church library operations is passions of pastors and chief operators in charge. They need to be willing to contribute to their local communities with their dedications and commitments.

The prevalence of thyroid nodule has been reported to be from 13 to 67% in the world and from 14 to 41% in Korea. Oh et al. (2010) reported that solid thyroid nodules were found in 39%. The prevalence of thyroid cancer was 2.5% among total subjects, and 6.5% among the subjects with thyroid nodules. The prevalence of papillary thyroid carcinoma (PTC) has increased, but the prevalence of follicular thyroid carcinoma and anaplastic thyroid carcinoma has decreased in Korea between 1980’s and 2000’s. The prevalence of BRAF mutations were reported to be 66∼83% in Korean PTC. The prevalence of ret/PTC rearrangement was 13%, but ras mutations were not detected. Jung et al. (2010) compared the clinicopathologic characteristics of 1,139 papillary thyroid microcarcinoma (PTMC) with those of 1,296 PTC more than 1 cm. Aggressiveness was less frequent in patients with PTMC, but recurrence and mortality rates for PTMC were also significantly lower than those of PTC (p<0.05). The prevalence of PTC variants in Korea was 6.7% and it was much lower than previously reported. The disease-specific survival and recurrence-free survival in classic PTC were not different from those of the favorable variants, but they were higher than those of the aggressive variants (p<0.01).

N/A Drug abuse is widespread in worldwide and has been associated with neurologic complication. Zipeprol is one of drugs which been abused for psychological satisfaction in some adolescents. This agent is non-opioid antitussive agent, which is not legally considered as being capable of creating dependence or abuse liability at therapeutic serum levels. But it has been reported that acute or chronic overdose create neurologic complication such as convulsion as well as dependence. Recently we experienced six zipeprol abusers who admitted due to convulsion and variable neurologic symptoms. The aim of our study was to determine the role of Tc-99m- HMPAO brain SPECT in those patients. EEG and brain CT showed no abnormal finding, but brain SPECT showed focal or multiple perfusion abnormalities in frontal, parietal, occipital cortex, basal ganglia, thalamus and especially at temporal cortex. These results suggest that brain SPECT may be a useful diagnostic tool to evaluate the cerebral dysfunction indused by zipeprol abuse.
