The objectives of this study were to develope the uncooked-restructured belly (URB) and the processed-restructured bacon (PRB) using a protein-emulsion material (PEM) from pork, and to evaluate the quality characteristics of the URB and PRB. The PEM used to adhere muscle and fat tissues was prepared with a salt-soluble protein and emulsions (ratio 9:1). In color measurements, L$\^$*/, a$\^$*/ and b$\^$*/ values were significantly (p＜0.05) higher in URB than PRB. There was no significant difference in L$\^$*/ value between PRB from fresh pork and PRB from thaw pork PRB showed significantly (p＜0.05) higher water holding capacity compared to URB. Tensil strength of PRB was also significantly (p＜0.05) higher than that of URB. However, PRB from thawed pork marked the lowest color score among restructured meats in sensory evaluation. The scores of juiciness and tenderness were significantly (p＜0.05) Higher in URB compared to PRB. Consequently URB had significantly (p.＜0.05) higher score of overall acceptability than PRB. These results suggested that URB made with PEM could have a better sensory characteristics compared to PRB. Results also suggested that the PEM would not be enough to adhere fresh muscle and fat tissues as much as PRB, even though the possibility of PEM was confirmed as a meat glue.

인삼은 우리나라에서 오랜 역사동안 많은 연구가 진행되어 왔으며, 현재는 다양한 방법으로 홍삼과 흑삼으로 만들어 식품, 화장품, 의약품 등 다양한 방면으로 사용하고 있다. 본 연구에서 시중에서 구매한 새싹삼(인삼새싹) 잎/줄기에 함유된 진세노사이드(Re, Rg1, Rb1, Rg3, Rh1) 함량을 높이기 위하여 증숙과 초음파 추출조건에 관한 연구를 수행하여 우수한 항노화 소재를 개발하기 위하여 실시하였다. 실험은 새싹삼 잎/줄기를 증숙 온도와 시간의 조건에서 진세노사이드 함량이 가장 높은 조건을 선정하였으며, 선정된 조건의 새싹삼 잎/줄기에 파장과 출력에 대한 조건으로 초음파 추출을 진행하여 진세노사이드가 가장 높은 함량을 보이는 조건을 선정하였다. 그 결과 새싹삼 잎/줄기추출물(GSE; Ginseng Sprout Extract)의 진세노사이드 함량은 4.8 mg/g으로 확인되었으나 증숙공정을 통해 8.82 mg/g으로 함량이 증가되었으며, 상기 증숙된 새싹삼 잎/줄기에 초음파공정을 적용하여 추출한 새싹삼 잎/줄기초음파추출물(SU-GSE; Steaming & dry Ultrasonication-Ginseng Sprout Extract)에서는 최대 10.65 mg/g으로 함량이 증가되었다. 반면, 새싹삼 뿌리의 진세노사이드는 2.30 mg/g으로 확인되었으나 증숙공정을 통해 4.95 mg/g으로 함량이 증가되었으며, 초음파추출공정을 통해 최대 5.82 mg/g으로 함량이 증가된 것을 확인할 수 있었으나, 새싹삼 잎/줄기에 비해 진세노사이드 함량이 낮은 것을 확인하였다. 항노화 소재로의 활용가능성을 평가하기 위하여 새싹삼 잎/줄기추출물 GSE와 SU-GSE에 대한 세포생존률, 항산화 및 항노화에 대한 효능평가를 진행하였으며 GSE의 경우 $100{\mu}g/ml$에서 세포생존률이 82.4%를 보인 반면 SU-GSE에서는 $1,000{\mu}g/ml$의 농도에서 101.8%의 세포 생존률을 보였다. 항산화 활성의 경우 GSE와 SU-GSE $100{\mu}g/ml$ 농도에서 각각 52%와 81%의 항산화 활성을 나타냄으로써 SU-GES의 조건에서 항산화 활성이 우수한 것으로 확인되었다. 또한, 항노화 활성에 대한 실험결과 MMP-1 유전자 발현에 대한 억제율을 비교한 결과 GSE와 SU-GES $100{\mu}g/ml$의 농도에서 각각 18%와 29%의 억제율을 보임에 항노화 소재로의 활용가능성을 확인하였다.

To analyse components of fresh ginseng and some white ginsengs with different processing conditions, approximate composition, extraction yield, total saponin content and composition and free sugar composition of fresh ginseng, white ginseng, Taeguksam A and Taeguksam B were examined. Yield of hot water extraction was two times higher than that of 80% methanol extraction. Hot water extraction yields of fresh ginseng, white ginseng, Taeguksam A and Taeguksam B were 56.4, 39.9, 42.9 and 46.6%, respectively, while the 80% methanol extraction yields ranged from 15.8% to 21.9%. Total saponin contents of the above were 2.40, 1.73, 1.45 and 1.79%, respectively, with hot water extraction and were 2.15, 2.99, 2.81 and 2.35%, respectively, with 80% methanol extraction. Ginsenoside compositions of the above varied with processing conditions and extraction solvents. Hot water and 80% methanol extracts of fresh and white ginseng composed of fructose, glucose, sucrose and maltose. Rhamnose was detected only in the extract of Taeguksam A and B.

Marine magnetic surveys provide a rapid and cost-effective method for pioneer geophysical survey for many purposes. Sea-surface magnetometers offer high accuracy but are limited to measuring the scalar total magnetic field and require dedicated cruise missions. Shipboard three-component magnetometers, on the other hand, can collect vector three components and applicable to any cruise missions. However, correcting for the ship's magnetic field, particularly viscous magnetization, still remains a challenge. This study proposes a new additional correction method for ship's viscous magnetization effect in vector data acquired by shipboard three-component magnetometer. This method utilizes magnetic data collected simultaneously with a sea-surface magnetometer providing total magnetic field measurements. Our method significantly reduces deviations between the two datasets, resulting in corrected vector anomalies with errors as low as 7-25 nT. These tiny errors are possibly caused by the vector magnetic anomaly and its related viscous magnetization. This method is expected to significantly improve the accuracy of shipborne magnetic surveys by providing corrected vector components. This will enhance magnetic interpretations and might be useful for understanding plate tectonics, geological structures, hydrothermal deposits, and more.

경부 염증을 주 증상으로 하는 이상와 누공의 치료로써, 전통적으로 외과적 절제술이 주로 시행되었으나, 근래에 들어서는 수술 관련 위험성이 적은 삼염화아세트산 소작술이 선호되고 있다. 본원에서, 2004년 5월부터 2013년 3월까지 컷 다운 튜브를 이용한 삼염화아세트산 소작술을 통해 이상와 누공을 치료한 5명 환자의 증례를 보고한다. 이전까지의 삼염화아세트산 소작술에서, 여러 도구를 이용해 누공의 입구만을 막는 시도를 했던 것과는 달리, 본 증례에서는, 컷 다운 튜브를 이용해 20~50%의 삼염화아세트산을 누공로에 주입함으로써, 이상와 누공 전장을 폐쇄하고자 하였다. 3명의 환자에서는 추적 관찰 중 재발 소견 없었으며, 2명의 환자는 추적 관찰 기간 중 재발하여 삼염화아세트산 소작술을 재시행하였다. 모든 증례에서 부작용 및 합병증은 발생하지 않았다.

Anemia commonly occurs in kidney transplantation (KT) recipients. Many factors such as viral infection, bleeding, erythropoietin deficiency, and immunosuppressants are the causes of chronic anemia in KT recipients. We report 2 cases who developed severe anemia caused by parvovirus B19 infection and were successfully treated with intravenous immunoglobulin in pediatric KT recipients.

Purpose: The objectives of this study were to investigate the degrees of emotional labor and the effects of Type A personality, emotional expressiveness, job stress, and social support on the emotional labor among clinical nurses. Methods: The subjects of this study were the clinical nurses working at the general hospital in Seoul. The subjects were selected by quota sampling in consideration of the length of employment and the working units. The self-reported questionnaires were administered to 286 clinical nurses and the data were analyzed with SPSS 12.0 software Results: The level of emotional labor of the subjects was revealed moderate to high. Significant explanatory variables of the degrees of emotional labor included psychological job load, the lack of job autonomy, and role conflicts. These three variables demonstrated the explanatory power of 11.4% of the emotional labor. Conclusion: The findings suggested that the intervention program intervening emotional labor should be developed in order to improve psychological job load, the job autonomy, and role conflicts among clinical nurses.
