본 연구는 제5기 국민건강영양조사를 이용하여 만 19~64세 성인 10,608명을 대상으로 BMI를 기준으로 분류한 체형과 주관적 체형인식의 차이를 기준으로 실제 체형보다 마르게 인식하는 RL군, 실제 체형을 올바르게 인식하는 RA군과 실제체형보다 비만하다고 인식하는 RH군으로 분류하여 각 그룹의 영양소 섭취, 체중조절 여부, 정신건강상태를 비교하였다. 1) RH군의 비율은 19~29세, 30~49세, 50~64세에서 남자는 12.1%, 9.5%, 10.0%였고, 여자는 31.2%, 29.0%, 20.3%로 여자에서 RH군의 더 비율이 높았고, RL군의 비율은 남자 19~29세, 30~49세, 50~64세에서 26.0%, 24.2%, 28.8%였고, 여자는 3.9%, 5.7%, 14.6%로 남자에서 RL군의 비율이 더 높았다. 2) 남녀 연령대별 BMI에서 남자 19~29세, 30~49세의 평균 BMI는 RA군이 가장 높고 RH군, RL군 순위였으며 50~64세에선 RL군이 가장 낮았다. 여자 19~29세에서는 RL군이 가장 낮았으며, 30~49세, 50~64세에선 RA군이 가장 높고 RH군, RL군 순이었다. 3) 남자의 경우 19~29세에서 탄수화물 섭취량은 RH군이 가장 낮게 섭취하였다. 여자는 30~49세에서 총에너지 섭취량은 실제체형보다 비만하게 인식하는 RH군이 에너지 섭취가 가장 낮았으며 RL군이 가장 많이 섭취했다. 여자 30~49세와 50~64세에서 탄수화물 섭취량이 RH군에서 가장 낮았고 총에너지 섭취량에 따른 탄수화물 섭취비율 또한 30~49세에서 실제체형보다 비만하게 인식하는 RH군에서 가장 낮아 실제체형보다 비만하게 인식하였을 때 탄수화물 섭취량이 적었으며 이로 인해 에너지 섭취량이 적었다. 4) 남자 50~64세를 제외한 남녀 모든 연령대에서 실제체형보다 비만하게 인식하는 RH군이 체중 감량 시도를 가장 많이 한 것을 알 수 있고, 남자 19~29세, 30~49세, 전 연령대의 여자에서 실제체형보다 비만하게 인식하는 RH군에서 체중이 증가한 경우가 가장 적었지만, 주별 중등도 운동일수에는 차이가 없어서 체형인식과 운동량은 관련이 없었다. 5) 남자 19~29세에서 실제체형보다 비만하게 인식하는 RH군이 우울감을 느낀 비율이 높았지만, 남자 50~64세에서는 실제체형보다 마르게 인식하는 RL군이 우울감 경험비율과 스트레스가 높아 체형인식에 따른 우울감은 남성에서 연령별로 차이를 보였다. 결론적으로 본 연구를 통해 성별과 연령에 따라 다소 차이가 있지만 실제체형보다 자신을 비만하다고 인식할 때 탄수화물의 섭취를 줄이고, 체중조절을 더 시도하며, 젊은 남성들에서 우울감 경험률이 높음을 알 수 있었다. 이에 따라 올바른 신체상을 확립하기 위해선 마른 몸매 선호에 대한 왜곡된 사회문화적 분위기를 개선하고 자신의 체형에 대한 올바른 인식이 필요함을 확인하였다. Purpose: The objective of this study was to examine the effect of the body shape discordance, the difference between true body type based on body mass index (BMI) and self-recognized body image, on nutrient intake, weight control attempt, and mental health in Korean adults. Methods: Subjects were persons aged 19~64 years (4,382 men and 6,226 women) who participated in the 2010~2012 Korea National Health and Nutrition Examination Survey. Subjects were categorized as RL (Group recognized as lighter than BMI criteria), RA (Group with agreement between BMI criteria and self-recognized body image), and RH (Group recognized as heavier than BMI criteria) according to the difference between actual body type based on BMI and self-recognized body image. Results: Means of BMI in RH groups were lower than or equal to that of RA groups in all groups. No significant differences in total energy intake were observed among the three groups in men, but total energy intake was higher in the RL group than in the RH group in 30~49 year old women. Proportion of carbohydrate was the highest in the RL group among 30~49 year old women. RH groups paid more attention to weight control and had less weight gain than other groups. Higher proportions of depressive symptoms were reported in the RH group in 19~29 year old men, while a higher proportion of depressive symptoms were reported in the RL group in 50~64 year old men. Conclusion: The current findings suggest an association of perceiving body shape with energy intake, weight control attempt, or depressed mood in some age groups. Body image perception can influence eating, weight control attempt, and depressed mood, therefore proper body image perception should be established in Korean adults.

심명보,임지현,마대완,김미도리 국립중앙박물관 2011 박물관보존과학 Vol.12 No.-

국립김해박물관에서 발굴 조사가 이루어진 창원 다호리 유적에서 칠기검집에 철검이 끼워져 있는 상태의 칠초철검(漆鞘鐵劍)이 출토되어 이에 대한 보존처리 과정을 소개하고자 한다. 부식되어 상태가 취약한 청동제검심(劍鐔)은 강화제로 사용 중인 Incralac을 도포한 후 현미경을 이용하여 표면의 문양을 노출하였다. 칠기검집의 표면은 이물질을 제거함과 동시에 HPC 2% 수용액를 도포하여 피막을 보호하였다. 이물질 제거가 완료된 칠 표면에는 Caparol binder 5% 수용액를 2~3회 도포하여 보호피막을 형성한 다음 한지와 알루미늄 호일로 감싸 주었다. 이후 우레탄폼으로 유물을 안전하게 고정한 후 뒤집어 뒷면을 위와 같은 방법으로 보존처리를 실시하였다. 두께가 얇은 유물을 지지하기 위해 검집의 뒷면에 한지를 3겹으로 붙여 힘을 받을 수 있도록 하였으며, 내부의 철검은 검집에 도포한 HPC 2% 수용액를 주입하여 굳히는 정도로 마무리하였다. 이후 투명 아크릴 상자에 보관하여, 향후 전시 등에 활용될 수 있도록 하였다. This study presents an investigation into the conservation process of an iron dagger and scabbard, which are a lacquered scabbard and a dagger inserted in it, excavated in the Daho-ri relic of Changwon by Gimhae National Museum. The bronze dagger whose condition was poor due to corrosion was coated with Incralac, an intensifier, to reveal the surface patterns through a microscope. The lacquered scabbard was removed of foreign substances on the surface and coated with HPC 2%(in water) to protect the film. Applied onto the surface from which foreign substances were removed was Caparol Binder 5%(in water) two to three times to form a protective film and then faced with Korean paper. Once it was fixed in a polyurethane foam in a stable manner, it was turned over to receive the same process on the back. Three layers of Korean paper were attached to the back of the scabbard to support the thin artifact. HPC 2%(in water), which was applied to the scabbard, was also applied to the iron dagger inside for cementing effect. After all the processes were completed, the artifact was put in a transparent acrylic box for future display.

The placenta is an extraembryonic tissue that is formed between mother and fetus and mediates delivery of nutrients and oxygen from the mother to the fetus. Because of its essential role in sustaining the growth of the fetus during gestation, defects in its development and function frequently result in fetal growth retardation or intrauterine death, depending on its severity. Vertebrate Hox genes are well known transcription factors that are essential for the proper organization of the body plan during embryogenesis. However, certain Hox genes have been known to be expressed in placenta, implying that Hox genes not only play a crucial role during embryonic patterning but also play an important role in placental development. So far, there has been no report that shows the expression pattern of the whole Hox genes during placentation. In this study, therefore, we investigated the Hox gene expression pattern in mouse placenta, from day 10.5 to 18.5 of gestation using real-time RT-PCR method. In general, the 5' posterior Hox genes were expressed more in the developing placenta compared to the 3' Hox genes. Statistical analysis revealed that the expression of 15 Hox genes (Hoxa9, -a11, -a13/ -b8, -b9/ -c6, -c9, -c13/ -d1, -d3, -d8, -d9, -d10, -d11, -d12) were significantly changed in the course of gestation. The majority of these genes showed highest expression at gestational day 10.5, suggesting their possible role in the early stage during placental development.

김지영(Jiyoung Kim),신민서(Minseo Shin),김성희(Sunghee Kim),서지현(Jihyun Seo),마혜선(Hyesun Ma),양윤정(Yoon Jung Yang) 한국영양학회 2017 Journal of Nutrition and Health Vol.50 No.4

Purpose: This study examined and compared the associations of the iron status and food intake with the blood lead, mercury, and cadmium concentrations among Korean adolescent girls, premenopausal women, and postmenopausal women. Methods: The data from the 2010~2011 Korea National Health and Nutrition Examination Survey (KNHANES) was used. The subjects were classified into three groups: adolescent girls (n = 268), premenopausal women (n = 1,157), and postmenopausal women (n = 446). The iron status was assessed by hemoglobin, hematocrit, serum ferritin, and iron concentrations, as well as the total iron binding capacity (TIBC). The food intake was estimated by a food frequency questionnaire. Results: The blood heavy metal concentrations and poisoning rate in postmenopausal women were higher than in the other groups. The iron status in the adolescent girls and postmenopausal women was higher than that in the premenopausal women. In the adolescent girls, the iron status was inversely associated with the blood cadmium concentration. The dairy food intake was inversely related to the blood lead and cadmium concentrations. In premenopausal women, the iron status was inversely associated with the cadmium concentrations. The fish and shellfish food intakes were positively associated with the mercury concentrations. In postmenopausal women, the iron status was positively associated with the mercury and cadmium concentrations. Fast foods and fried foods were inversely associated with the lead concentration. Conclusion: The premenopausal women showed a lower iron status than the adolescent girls and postmenopausal women. The associations of the iron status with the blood heavy metal concentrations were different among the adolescent girls, premenopausal women, and postmenopausal women. In addition, the relationships of the food intakes with the blood heavy metal concentrations differed among adolescent girls, premenopausal women, and postmenopausal women. Further studies will be needed to confirm these findings.
