Purpose: ACR (American College of Radiology) offers variable parameters to PET/CT quality control by using ACR Phantom. ACR Phantom was made to evaluate parameters which are uniformity, attenuation, scatter, contrast and resolution. Manual analysis method wasn't good for the use of QC because values of parameter were changed as it may user and it takes long time to analysis. Ki-Chun Lim, a nuclear scientist in AMC, developed program that automatically analysis values of parameter by using ACR Phantom to overcome above problems. In this study, we evaluated automatic analysis program's usability, through the comparing SUV of each method, reproducibility of SUV when repeated analysis and the time required. Materials and Methods: Using Flangeless Esser PET Phantom, the ideal ratio of 4 : 1 hot cylinder and BKG but it actually showed a ratio of 3.89 to 1 hot cylinder and BKG. SIEMENS Biograph True Point 40 was used in this study. We obtained images using ACR phantom at Fusion WB PET Scan condition (2 min/bed) and 120 kV, 100 mAs CT condition. Using True X method, 3 iterations, 14 subsets, Gaussian filter, FWHM 4 mm and Zoom Factor 1.0, $168{\times}168$ image size. We obtained Max. & Min. SUV and SUV Mean values at Cylinder (8, 12, 16, 25 mm, Air, Bone, Water, BKG) by automatic program and obtained SUV by manual method. After that, we compared manual and automatic method. we estimate the time required from opened the image data to final work sheet was completed. Results: Automatic program always showed same result and same the time required. At 8, 12, 16 and 25 m cylinder, manual method showed 6.69, 3.46, 2.59, 1.24 CV values. The larger cylinder size became, the smaller CV became. In manual method, bone, air, water's CV were over 9.9 except BKG (2.32). Obtained CV of Mean SUV showed BKG was low (0.85) and bone was high (7.52). The time required was 45 second, 882 second respectably. Conclusions: As a result of difference automatic method and manual method, automatic method showed always same result, manual method showed that the smaller hot cylinders became, the lager CV became. Hot cylinders mean region size, the smaller hot cylinder size becomes we had some trouble in doing ROI poison setting. And it means increase in variation of SUV. The Study showed the time required of automatic method was shorten then manual method.

연구목적 : 우리나라에서 산업 재해로 신체적 손상을 입고 입원해 있는 일부 근로자들을 대상으로 PTSD 발병여부를 조사하고, 산업 재해와 관련된 위험 인자를 파악하여 산업재해 이후 근로자들이 겪게 될 신체적 건강문제 뿐만 아니라 정신적 건장 문제 회복에 도움을 주고자 하였다. 방 법 : 2000년 7월에서 2000년 9월 사이에 산업 재해로 인해 신체적인 부상을 입고 입원 중인 인천 소재 산재병원의 남성 입원환자 47명을 대상으로 PTSD 발병여부와 관련 인자를 연구하기 위하여 구조화된 설문 조사와 CAPS를 이용한 진단적 면담을 시행하였다. 결 과 : CAPS를 이용한 면접조사 결과 최종 연구 대상자 47명중 12명(25.5%)이 PTSD로 나타났으며, 모두 증상의 지속 기간이 3개월 이상인 만성 외상후 스트레스장애로 분류되었다. PTSD군 12명과 non-PTSD군 45명을 비교한 결과 BDI, STAI-I, STAI-II, IES 점수는 PTSD 군에서 유의하게 높게 나타났다. 또한 SCR-90-R의 세부항목 중 편집 사고를 나타내는 PAR 점수가 유일하게 두 군 사이에 유의한 차이를 보이지 않았고 그 외의 항목들은 PTSD 군에서 유의하게 높았다. 산재 관련 위험 인자의 비교에서 환자가 주관적으로 보고한 의식의 상실 경험만이 PTSD군에서 유의하게 높게 나타나 이전의 다른 연구자와 일치된 소견을 보였다. 결 론 : 이상의 결과는 산재 사고 이후에 PTSD가 발생하고, 증상이 장기간 지속되어 만성화를 겪을 가능성이 있다는 것을 보여준다. 위험 인자 중에서 사고 관련 위험 인자로 의식의 상실에 대한 주관적인 보고만이 관련성이 있는 것으로 나타났으나, 그 외의 다른 인자들은 관련서이 없는 것으로 나타났다. 그러나 여러 가지 연구의 제한점이 많으므로 연구 시점을 달리하고 많은 대상자를 포함한 후속 연구를 시행해야 산업재해와 PTSD에 대한 이해를 높일 수 있을 것으로 사료된다. Objectives : This study was conducted to assess the development of posttraumatic stress disorder(PTSD) after occupational physical injuries and the risk factors in occupational accident patients for PTSD. Methods : Forty-seven occupational accident patients with physical injuries were administered BDI. STAI I and II, SCL-90-R, IES and questionnaires for risk factors and Clinician-Administered PTSD Scale(CAPS). Results : 1) 12 patients(25%) were diagnosed as PTSD. 2) The BDI, STAI I and II and IES scores are significantly high(<0.05) in PTSD group than non-PTSD group. 3) The subscales of SCL-90-R, with an exception of PAR subscale, showed higher scores(<0.05) in PTSD group. 4) The loss of consciousness(LOC) was only significant risk factor in the occupational accident related factors(<0.05). Conclusion : The results of this study show the development of PTSD among occupational accident patients. The loss of consciousness(LOC) was the only significant risk factor for PTSD in occupational accident patients.

This was done to find optimal conditions of musical aptitude test as a preliminary study for developing such test. In this study. five considerations might be suggested as follows. First. an united concept about musical aptitude needs to be established through professional musician's theoretical judgements and empirical studies such as factor analysis. Second, test materials need to be adopted from musical context itself rather than from simple mechanical sounds. Also, it is necessary that test contents should include musical sensitivity and musical preferences Third. in developing musical aptitude tests, a paradigm needs to be changed from indirect measurement to direct measurement. Fourth, considerations on measurement characteristics such as reliability, validity, standardization should be emphasized. Fifth, it is necessary to develop our own musical aptitude test which is appropriate to our cultural background.

Hereditary spherocytosis is a common cause of hemolysis and hemolytic anemia. Some children remain asymptomatic into adulthood but others may have severe anemia with pallor, jaundice and fatigue. After infancy, the spleen is usually enlarged, and pigmentary gallstones may form as early as age 4~5 year. But it increases abruptly after age 10 year. At least 50% of unsplenectomized patients ultimately form gallstones, although for the most part they remain asymptomatic. We report herewith a case of multiple gallstone with obstructive jaundice in 5 years old patient with hereditary spherocytosis.

석산폐석을 활용한 쇄석골재의 물리적 및 화학적 특성 연구

송기범,김경수 大田産業大學校 1996 한밭대학교 논문집 Vol.13 No.0201

골재의 수요는 매년 크게 중가하고 있으나 천연 골재는 점차 고갈되어 가고 있다. 따라서 기존석산들에서 발생되는 폐석자원을 쇄석골재로 활용하면 일거양득의 효과가 있다. 본 연구는 국내에서 가장 대규모 석산단지인 포천 및 익산지역 기존석산에서 발생되는 석산폐석에 대한 물리적, 화학적 및 광물학적 시험·분석을 실시하여, 쇄석골재로서 석산폐석의 특성규명과 활용가능성을 평가하였다. 연구결과, 포천과 익산지역에서 발생되는 석산폐석을 쇄석골재로 활용할 수 있을것으로 판단되었으며, 폐석자원을 쇄석골재로 활용함으로써 골재의 수요에 보충하고, 산림 및 자연경관의 훼손과 환경오염을 야기할 수 있는 석산골재 신규개발 의 억제에도 효과가 기대된다. The natural aggregate have been enormously consumed and eventually scarce due to the gradual growth of urbanization during the last several decades, a replacement of the conventional material being necessary. Such a replacement can be achieved by the utilization of quarry wastes. The annual quantity of the wastes produced in the Pocheon and Igsan areas, which are known as the biggest quarry sites in this country, was estimated and their quality was investigated as well, The quarry wastes collected from both of the areas were tested for their physical properties, chemistry and mineralogy in order to appraise their utilization potential as crushed aggregate. Based on all the test results, the wastes of the quarries in the Pocheon and Igsan areas May be utilized as crushed aggregate. It is expected that the quarry wastes will control the future development of quarry only for the production of aggregate which may give rise to the damage and pollution of natural environment.

This study was carried out to determine the effect of various fertilizer levels on the growth and yield of Agrimony. this experiment was conducted for 2years from 1998 to 1999 in Medicinal Plant Experiment Station, Kyungnam ARES. The results obtainned were summarized as follows : 1. The growth characteristics such as plant height, tillers and leaf numbers were more increased at 22-10-10 plot than of other fertilizer levels. 2. Variations of percent flowering of Agrimonia pilosa L. treated with different fertilizer levels were more increased at 22-10-10 plot than of other fertilizer levels. 3. Yield per 10a of Agrimonia pilosa L., Fresh weight was 1,500kg in 22-10-10 plot, and 243kg in non-treatment plot. The dry weight was 736kg in 22-10-10 plot, and 96kg in non-treatment plot. Yield of Seed and Fruit following to different application levels was highest at the fertilizing plot of N, P2O5, K2O=22-10-10.
