The patients who visited the Health Promotion Center were compared between the visceral fat area according to CT fat measurement position and the visceral fat area measured by Inbody. In the CT measurement, the visceral fat area measured at the L4-5 and CT Umbilicus positions was not different regardless of gender. In addition, there was no difference between CT visceral fat area and Inbody visceral fat area in the correlation between visceral fat area according to CT measurement position and visceral fat area measured by Inbody. The highly correlated CT measurement position were male L4-5, L5-S1, female L3-4, L4-5, L5-S1, and Umbilicus. In addition, when studying the relationship between the inbody visceral fat area and CT visceral fat area regardless of gender, it is suggested to compare the visceral fat area at the CT L4-5 position.

Parosteal lipoma is a rare type of lipoma, the incidence being approximately 0.3% of all lipomas. Moreover, parosteal lipoma coexisting with osteochondroma is extremely rare. A few cases with coexistence of osteochondroma and parosteal lipoma have been reported and they were thought to be reactive changes of adjacent bone by parosteal lipoma. However, temporal relationship of these tumors could not be explained. Here, we report a case of parosteal lipoma associated with osteochondroma of the right ilium developed over 6 years, with follow-up radiographs.

The purpose of this study was to analyze the relationship between hematologic hyperlipemia index and severity of fatty liver abdominal ultrasonography. A total of 412 adults from January 1, 2017 to December 31, 2017 who underwent abdominal ultrasonography and hematologic data within 3 months of the ultrasound examination, were the target of the investigation. As a result of the study, the hematological values according to the degree of fatty liver were statistically significant in triglyceride, AST and ALT (p<.05), fatty liver was associated with gender, triglyceride, AST and ALT (p<.05). In conclusion, the degree of fatty liver was not directly related to the hematologic value of hyperlipidemia, but we confirmed the necessity of co-management with fatty liver and hyperlipidemia by confirming its relevance.

This study retrospectively analyzed the test results of 441 patients who visited Hospital I in Busan from October 2021 to December 2021 and conducted both mid-term ultrasound and fibroscan tests. The purpose of the study was to investigate the usefulness of fibroscan in inter-fat evaluation by conducting correlation analysis and chi-squared test of inter-fat evaluation using liver ultrasound and fibroscan. As a result of analyzing the correlation between the fatty liver reading result of abdominal ultrasound and Fibroscan UAP, the correlation was found to be r=0.600 and p=0.000. In the inter-provincial evaluation, Fibroscan showed high validity in predicting objective results using inter-provincial values.

우리나라는 지속적인 저출산과 고령화로 인해 지방 소멸 위험지역이 점차 늘어나고 있다. 본 연구는 지방 소멸과 관련된 다양한 요인을 '인구 소멸'이라는 키워드를 포함하는 신문 기사에 대한 토픽모델링을 통해 발견하고, 추출된 토픽과 관련된 공공 데이터를 수집하여 비슷한 특징을 가지는 지역을 묶는 군집분석을 수행한다. 그리고 지방소멸위험지수로 분류된 소멸 위험지역과 군집분석 결과를 비교한다.

본 연구에서는 SPI지수를 이용하여 내륙지방의 가뭄을 분석하였다. 본 연구에서 적용된 SPI가뭄 지수는 국내에서 발생하였던 과거의 가뭄사상 특성을 분석하기 위하여 SPI(Standardized Precipitation Index)지수를 선정하여 안동관측소의 1983년~2016년까지의 월평균 강우자료를 취합하여 가뭄지수를 산정하였다. 또한 이를 이용하여 가뭄발생을 3개월, 6개월, 9개월, 12개월로 나누어 가뭄기간 조사를 통하여 내륙지방의 대표적인 도시인 안동지방의 가뭄특성 및 주기를 분석하였다. 그 결과, SPI-3은 겨울과 이듬해인 봄까지는 가뭄현상이 심화되며, 여름철에는 장마로 인해 가뭄이 완화되는 것으로 분석되었다. 또한, 가뭄의 주기성을 분석한 결과 5년 내외 주기가 유의한 것으로 나타났으며, SPI-3의 분석결과 1년에서 2년의 주기성을 보였다. 따라서 SPI가뭄지수를 이용하여 안동지역의 가뭄을 분석한 결과 2000년 이후 길게는 6년을 주기로 가뭄지수가 나타났으며, 관측된 강우자료를 이용하여 가뭄을 산정하데 있어서 효과적인 분석에 적용될 수 있을 것으로 판단된다.

Fat accumulation in adipocytes occurs through the process of adipogenesis in which preadipocytes differentiate into adipocytes. Obesity is a metabolic disorder caused by excessive accumulation of fat in the body, which increases the incidence of cardiovascular diseases, hypertension, type 2 diabetes, hyperlipidemia, and various cancers. Recently, inhibition of adipocyte differentiation was shown to be a potential antiobesity strategy. In this study, the inhibitory effect of dichloromethane fractions from Illicium verum Hooker fil. water extract on the differentiation of 3T3-L1 preadipocytes to adipocytes was investigated. Dichloromethane fractions from I. verum Hooker fil. significantly inhibited adipocyte differentiation when applied during the adipocyte differentiation process, as assessed by measuring fat accumulation using Oil-red O staining. In addition, dichloromethane fractions from I. verum Hooker fil. reduced important adipogenic transcription factors, such as CCAAT/enhancer binding protein ${\alpha}$ ($C/EBP{\alpha}$), $C/EBP{\beta}$, and peroxisome proliferator activated receptor ${\gamma}$ ($PPAR{\gamma}$). The expression of FAS and LPL, which are terminal differentiation markers of mature adipocytes, was also reduced in the 3T3-L1 adipocytes treated with dichloromethane fractions from I. verum Hooker fil. In addition, the treatment significantly inhibited mitotic clonal expansion, which is essential for adipocyte differentiation, by arresting the G1 phase of the cell cycle. Taken together, these results suggest that dichloromethane fractions from I. verum Hooker fil. may be a natural material with antiobesity effects.
