Purpose In present, MDCT has come into wide use. But outrun often occurs due to fast scanning and rotation time in lower extremity CT angiography with-64 MDCT. We studied the prevention to outrun in lower extremity CT angiography. Materials and Methods Between October 2006 and January 2007, during a period of 4 months, total 210 patients underwent a lower extremity CT angiography with 64 channel MDCT. We scanned patients from the level of lumber-spine three to feet in a single helical scan with 64 MDCT. Examination was scanned by each of different scanning methods. We changed the scan parameter in 3 ways. First, we set the delay time to 6.4 sec and the rotation time to 1sec. We called it to PG 1 (aorta slow). Second, we set the delay time to 20 sec and the rotation time to 0.4 sec. We called it PG 2 (aorta fast). Third method was same as PG 1 except of setting triggering level to popliteal artery. It was called for PG 3 (popliteal fast). The data from scanning was transmitted to 3D software program. Three-dimensional images were obtained using MIP(maximum intensity projection). Four radiologist evaluated all the results in reference to outrun, vein contamination, motion artifact and enhancement of vessel. Results In PG 1, there was no outrun. But it had some vein contamination and motion artifact because of long scan time. In PG 2, there was some outrun. But it had hardly vein contamination and motion artifact due to fast scan time. In PG 3, there was no outrun, too On the a:her hand, it had some vein contamination. Conclusion The best way to prevent outrun is program one (PG 1) or program three (PG 3) in lower extremity CT angiography with 64 MDCT. But each method has inherently a merit and demerit. We should use the protocol which is fit to patient history.

The objective of this study is to investigate a perceived discomfort and cause of Korean elderly in various activities such as work and leisure as well as in daily activities. 120 subjects (30 female and 30 male for each age: the young and elderly) participated in the interview type of questionnaire. Each participant answered to 41 items of activities of daily living. The examination of each item was progressed with 3 steps: whether to do the activity or not, degree of activity discomfort, and the reasons or causes of discomfort. Borg's CR10 scale is used to measure the degree of discomfort of daily activities. As a result, there are differences for the proportion of performers between two age groups, except for essential activities such as individual maintenance and housekeeping. The elderly complained about their daily activities more than the young did, and the degree of discomfort of women was significantly larger than that of men with aging. There are seven items, the mean degree of discomfort of which is over three points for the elderly, and they showed significant difference between two age groups. It was the important reason that physical capacities such as muscle strength and suppleness are declined. The results showed the characteristics of Korean elderly in the whole daily activities. These will be used to understand various life styles of them and to propose a field or direction of study related to the aging.

본 연구는 청소년 후기 삶의 만족도가 코로나19 전후로 어떠한 변화가 있는지와 삶의 만족도에 영향을 미치는 요인들을 알아보고자 실시되었다. 이를 위해 통계청에서 실시한 2019년 사회조사와 2021년 사회조사를 사용하여, 2019년 2,242명(남자 1,083명, 여자 1,159명), 2021년 2,262명(남자 1,089명, 여자 1,173명)의 자료를 분석했다. 분석 결과 여성은 가정 우선시 집단의 개인적 인간관계 만족도가 낮아졌고, 남성은 가정 우선시 집단의 개인적 인간관계 만족도가 상승했다. 청소년 후기 삶의 만족도와 성취 만족도는 2019년에 비해 2021년에 낮아지고 개인적 인간관계 만족도는 높아졌다. 다중 회귀분석 결과 청소년 후기의 삶의 만족도에 조사 연도(2021년)와 1인 가구, 대학 진학 이상, 전반적 생활 여건 변화, 개인적 인간관계 만족도, 성취 만족도가 영향을 미치는 유의미한 변인으로 나타났다. 본 연구의 의의는 코로나19 전후를 비교한 종단연구이며, 통계적으로 신뢰할 수 있는 통계청 사회조사 자료를 이용했다는데 있다. 추후 연구에서는 각 변인들 간의 인과관계를 살펴볼 필요가 있다. This study was conducted to find out what changes in life satisfaction in the late adolescents before and after COVID-19 and the factors affecting life satisfaction. To this end, data from 2,242 (1,083 men and 1,159 women) in 2019 and 2,262 (1,089 men and 1,173 women) in 2021 were analyzed using the 2019 social survey conducted by the National Statistical Office. According to the analysis, women's satisfaction with personal relationships in the family-first group decreased, and men's satisfaction with personal relationships in the family-first group increased. Life satisfaction and achievement satisfaction in the late adolescents decreased in 2021 compared to 2019, and personal relationship satisfaction increased. As a result of multiple regression analysis, it was found that the survey year (2021), single-person households, college entrance, changes in overall living conditions, personal relationship satisfaction, and achievement satisfaction affect life satisfaction in the late adolescents. The significance of this study is that it is a longitudinal study comparing before and after COVID-19, and statistically reliable social survey data from the National Statistical Office were used. Future research suggests that it is necessary to examine the causal relationship between each variable.

상주 동천 상류부 산간분지의 출구에 위치하는 공검지는 통일신라시대 말기에 조성된 것으로 파악된다. 공검지 제방이 축조되기 이전에는 분지에 넓은 습지가 형성되었으며, 갈수기에는 공기 중에 노출되면서 대단히 치밀한 실트층이 퇴적되었다. 청동기시대 초기와 초기철기시대의 분지에는 주로 밭에 기장을 재배하였다. 삼국시대에는 논농사와 밭농사가 이루어졌을 것으로 생각되지만 퇴적층이 발견되지 않았다. 제방이 축조되면서 분지 내 밭에는 기장을 재배하며 논농사를 병행하였을 것이다. 공검지 일대의 청동기시대 초기기후는 냉량하였고 초기철기시대 동안의 기후는 대체로 온난하였다. 제방이 축조된 통일신라시대 말기부터 고려시대 중기까지도 역시 온난하였으나, 이후 냉량, 온난한 시기를 반복하다가 고려시대 말부터 점차 냉량해진다. Gonggeomji, located at the outlet of intermontane basin in the upper reaches of Dong River, is known as being constructed in the late Unified Silla Dynasty. Extensive wetlands were developed before the construction of embankment at Gonggeomji and very compact silty layers were deposited during dry seasons. Paniceae was cultivated on a dry field in the basin during the early Bronze and Iron Ages. Although it is supposed that agricultural activities on a paddy and dry field prevailed during the Three Kingdoms Age, the indicating layer was not found. As the construction of the embankment, Oryza sativa as well as Paniceae were cultivated in the basin at the same time. The climates during the early Bronze are cool and Iron Ages are estimated to be generally warm. From the late Unified Silla Dynasty and middle Goryeo Dynasty when the embankment was constructed, it was still warm, and then, shows alterations between cool and warm conditions. Since the late Goryeo Dynasty, it gradually became cool.

Reserved liver function is one of the most important determinants of survivial in advanced hepatocellular carcinoma (HCC). Especially in cirrhotic patient with decompensated liver function, sorafenib for HCC with main portal vein invasion have limited efficacy and survival benefit. Therefore many clinicians or centers still try locoregional therapy (LRT) such as transarterial chemoembolization (TACE), radiation therapy (RT), or combination with LRT and sorafenib in this situation. However this multidisciplinary approach may increase treatment related toxicity such as liver failure, etc. Recently, studies for combination of RT and sorafenib for HCC with portal vein invasion have been tried and reported not only bettertherapeutic efficacy, but also more hepatic toxicity.Based on above suggestions, we herein offer our experience of a patient that although achieved survival gain via partial remission of intrahepatic tumor and main portal vein thrombosis and metastatic lymph node by combination therapy of RT and sorafenib, finally expired due to hepatictoxicity. Further study, maybe regarding a combination of locoregional and systemic therapy, is necessary on how to manage decompenstated cirrhotic patients with HCC with main portal vein invasion.

Hepatocellular carcinoma (HCC) patients with main portal vein invasion have a poor prognosis associated with a median survival time of 2.7 months. Though many guidelines recommended sorafenib in HCC patients with macrovascular invasion (MVI), many clinicians or centers still select locoregional therapy (LRT) such as transarterial chemoembolization (TACE), radiation therapy (RT), or combination with LRT and sorafenib because the survival improvement by sorafenib only is expected to be shorter than that without MVI. However this multidisciplinary approach may increase treatment related toxicity such as liver failure etc. Stereotactic body radiation therapy (SBRT) is new technology providing very highly conformal ablative radiation dose for a small numbers (3-5 fractions) of large fraction size and is expected to new effective modality for HCC with MVI. Based on above suggestions, we herein offer our experience of a patient with perforation of radiation induced gastric ulcer after complete remission of tumor and main portal vein thrombosis by combination therapy of SBRT and sorafenib. Further study, maybe regarding a combination of locoregional and systemic therapy, is necessary on how to manage HCC patients with main portal vein invasion.
