In Seongju, Gyengsangbuk-do, the Placenta Chamber (胎室, Taesil) of 18 sons and a son of the crown prince of King Sejong(世宗大王) is located in one place. Taesil refers to the place where the umbilical cord and placenta, which are separated when the baby is born, are placed in a jar made of pottery and stone box and then buried on the ground. The placenta chamber in Seongju has the Buncheong ware (粉靑沙器) cover buried on the ground to protect the baby's placenta. These covers are all hemispherical, with a diameter of more the 20cm. The decorations were made using black and white inlaid techniques only on the outside. The Buncheong ware cover with this shape and pattern has been confirmed only in the placenta chamber in Seongju. This study targets 6 of the Buncheong ware cover whose owners were identified, when and where they were prepared, what the stylistic features and meanings are, and where it was produced. The results of the study are as follows. First, ss a result of reviewing the production background and procurement system of this bowl, it was inferred that it was sourced from Jangheunggo (長興庫) at the central government office, between 1436 and 1439, when the event to bury the placenta of royal members in the ground was the most active. Second, it analyzed the unique features of this cover, such as the shape, pattern, and baked traces. The shape and pattern were compared to the ritual objects contained in the Sejong Silok Oryeui (『世宗實錄』 「五禮」, Five Rites of King Sejong Chronicle) and the lid of the royal placenta jar made in the 15th and 16th centuries. Third, this study suggests that the baking method was based on the shape and location of the traces remaining outside the cover. Finally, the following data were used to estimate the production site: the relationship with the ‘ Jagiso (磁器所, ceramic workshop) registered in the Sejong Silok Jiriji (『世宗實錄』 「地理志」, Geographical Appendix of King Sejong Chronicle); various records of contribution and dedication about the Buncheong ware made here; and the Buncheong ware and related tools excavated from the kiln site in the area. The place where the Buncheong ware cover was produced is estimated to be the most likely production site for the kiln site in Chunghyo-dong Kiln Site, located in Jeolla-do province by synthesizing the data above. 세종의 대군·군과 세손을 포함하여 총 19기 태실이 모여 있는 성주 세종대왕자 태실은 여러 태실이 한 공간에 조 성된 유일한 사례이자, 태를 봉안·보호하는 장태용 그릇의 구성과 조형 역시 다른 곳과 구별되어 주목받아왔다. 본 글 은 성주 태실에서 출토된 장태용 그릇 중 하나인 <분청사기 상감연판문 반구형뚜껑>에 집중하여 제작의 특징을 구 명하고 제작지 고찰에 초점을 맞추었다. 연구 대상은 태주가 확인된 6점에 한정하였다. 성주 태실은 세종 연간 왕실의 장태와 태실 조성에 관한 다양한 논의와 행사가 가장 성행한 1436~1439년에 계획 되고 세워졌을 것이다. 태를 담은 항아리를 덮어 보호하는 목적으로 태와 함께 장태 된 이 분청사기 뚜껑은 장태에 필요 한 여러 잡물 가운데 중앙 관청에 분정된 잡물의 용도와 일치하며, 장흥고에서 장태 행렬 이전에 마련하여 조달한 품목 으로 유추된다. 뚜껑의 크기·형태·장식 등의 조형적 특징은 15~16세기 왕실용 태항아리 뚜껑과 공통되는 부분이 있고, 『세종실록』 「오례」에 수록된 길례용 제기 및 가례용·빈례용 준작 기물과 친연성이 높다는 점을 확인하였다. 뚜껑의 꼭지 를 에워싸고 있는 태토빚음의 번조받침 흔적은 15세기 후반~16세기 전반 왕실용 태항아리 뚜껑에 남아 있는 흔적과 상 통한다. 덧붙여 번조받침 흔적의 형태와 위치를 통해 이 분청사기 뚜껑은 꼭지를 아래로 향하게 한 후 받침 도구와 갑발 등을 이용하여 번조하였을 가능성이 있다. 이상의 분석과 『세종실록』 「지리지」에 등재된 자기소 내용, 15세기 전반 자기 의 진헌·공납 관련 기록, 현재까지 조사된 분청사기 가마터 출토 유물 등의 정보를 종합적으로 검토하였을 때 이 분청사 기 뚜껑을 제작한 곳은 현 광주광역시 북구 충효동 분청사기 가마터가 가장 유력할 것으로 사료된다.

This study aimed to investigate which areas AI is sensitive when inputting panoramic radiographs with dental area masked and when inputting unmasked ones. Therefore, the null hypothesis of this study was that masking dental area would not make a difference in the sensitive areas of osteoporosis determination of AI. For this study 1165 female(average age 48.4 ± 23.9 years) from whom panoramic radiographs were taken were selected. Either osteoporosis or normal should be clearly defined by oral and maxillofacial radiologists. The panoramic radiographs from the female were classified as either osteoporosis or normal according to the mandibular inferior cortex shape. VGG-16 model was used to get training, validating, and testing to determine between osteoporosis or normal. Two experiments were performed; one using unmasked images of panoramic radiographs, and the other using panoramic radiographs with dental region masked. In two experiments, accuracy of VGG-16 was 97.9% with unmasked images and 98.6% with dental-region-masked images. In the osteoporosis group, the sensitive areas identified with unmasked images included cervical vertebrae, maxillary and mandibular cancellous bone, dental area, zygomatic bone, mandibular inferior cortex, and cranial base. The osteoporosis group shows sensitivity on mandibular cancellous bone, cervical vertebrae, and mandibular inferior cortex with masked images. In the normal group, when unmasked images were input, only dental region was sensitive, while with masked images, only mandibular cancellous bone was sensitive. It is suggestive that when dental influence of panoramic radiographs was excluded, AI determined osteoporosis on the mandibular cancellous bone more sensitively.

Formation mechanism of residual carbon layer, frequently observed in the $CuInSe_2$ (CIS) thin film prepared by direct solution coating routes, was investigated in order to find a way to eliminate it. As a model system, a methanol solution with dissolved Cu and In salts, whose viscosity was adjusted by adding ethylcellulose (EC), was chosen. It was found that a double layer, a top metal ion-derived film and bottom EC-derived layer, formed during an air drying step presumably due to different solubility between metal salts and EC in methanol. Consequently, the top metal ion-derived film acts as a barrier layer inhibiting further thermal decomposition of underlying EC, resulting a formation of bottom carbon residue layer.

This study evaluated the influence of cooking methods (blanching, pan-frying, and microwaving) on the antioxidant activity of Ligularia fischeri (LF) using myoglobin methods against five different reactive oxygen species (ROS) (i.e., 2,2-diphenyl-1-picrylhydrazyl (DPPH), hypochlorite ions, hydroxyl radicals, peroxyl radicals, and peroxynitrite ions). With respect to DPPH scavenging activity, the antioxidant activities of blanched LF and pan-fried LF were significantly higher (P<0.05) than that of fresh LF for all cooking times. Pan-fried LF and microwaved LF showed higher antioxidant activities against hydroxyl radicals and peroxyl radicals than uncooked LF, while the protective effect of blanched LF was low, except for the at the 3 min cooking time point. Microwaved LF showed high antioxidant activity against all ROS at the 2 min cooking time point. Interestingly, LF that had been microwaved for 2 min and 3 min had high antioxidant values, whereas blanched LF and pan-fried LF had low antioxidant values. The activities of cooked LF against five different ROS were characterized comprehensively by 5-axe cobweb charts.
