고로쇠수액의 채취적기인 3월에 채취한 수액과 후기인 4월에 채취한 수액의 이화학적 특성을 비교분석하고, 고로쇠 수액의 품질을 향상시키고자 한외여과 전후의 품질특성을 살펴보았다. 4월에 채취된 고로쇠수액이 3월에 채취된 수액보다 총균수 및 탁도가 높았지만, 한외여과 후 탁도는 비슷한 수준으로 감소하였고 미생물을 검출되지 않았다. 유기산, 총산, 유리당 및 총당 함량은 4월의 고로쇠수액이 3월 수액보다 약간 낮았지만, 조회분과 무기성분은 높은 함량을 나타내었다. 특히 칼슘은 3월과 4월에서 각각 129.40 및 166.38 ㎎/L로 4월이 높았다. 고로쇠나무 수액의 영양성분은 한외여과 후 약간의 감소를 나타내었지만 채취적기 이후(4월)에 채취되는 수액을 한외여과 할 경우 미생물제거 및 탁도 향상등 품질을 향상시킬 수 있으며, 무기성분이 더 많이 함유되어 있기 때문에 영양적으로 우수할 것으로 판단되었다. We investigated the effects of ultra filtration (UF) of Goroshoe (Acer mono Max.) sap collected in March and April. The total bacteria and turbidity of the sap collected in April were higher than in March. However, after UF, the turbidity decreased and bacteria were not detected. The total acidity and total sugar of the sap collected in April were lower than that collected in March. After UF, total acidity and total sugar decreased slightly in sap from both of the collection times. The crude ash and mineral content of the sap collected in April were higher than in March. In particular, the calcium and potassium content of the sap collected in April were 166.38 and 29.47 ㎎/L, respectively, which was much higher than in March. Again, after UF, the crude ash and mineral content were decreased in the sap from both collection times. We concluded that UF of Goroshoe sap increased its quality regardless of collection time.

The Sijeon (Licensed Markets) legally permitted by the government along the Jongno and the Namdaemunro Avenues played a central commercial role in Hanyang. However, after the opening of the port in the late Joseon era, the Licensed Markets suffered a blow and declined due to the introduction of a new product of civilization and the appearance of foreign merchants. Although the Licensed Markets, which have been maintained without major changes for a long time, have played a major role in the urban spatial structure, the exact location has not been still determined, and researches until now has remained limited for such that. In this study, based on the 1912 land survey records, the location of the Licensed Markets pre-and post- 1910 is identified, and the spatial change of the dismantling process is investigated.

소아에서 복막투석도관 삽입시 복강경을 이용한 방법과 기존의 수술법에 따른 초기 합병증 발생의 차이

정수인,이현영,이철구,서정민,이석구,김수진,곽민정,진동규,백경훈,Jeong, Soo-In,Lee, Hyun-Young,Lee, Cheol-Gu,Seo, Jeong-Meen,Lee, Suk-Koo,Kim, Su-Jin,Kwak, Min-Jung,Jin, Dong-Kyu,Paik, Kyung-Hoon 대한소아신장학회 2007 Childhood kidney diseases Vol.11 No.1

목적 : 복강경을 이용한 복막투석도관 삽입술은 직접 복강 내를 들여다보며 시술할 수 있어 위치 선정이 쉽고, 조직 손상이 적으며 합병증이 적다는 장점이 있으나, 소아에서의 경험은 많지 않다. 본 연구에서는 소아에서 복강경을 이용한 복막투석도관 삽입술의 유용성을 평가하고자 한다. 방법 : 2002년부터 2006년까지 삼성서울 병원에서 31명의 환아를 대상으로 복강경을 이용하여 복막투석도관 삽입술을 시행한 21례와 고식적 수술 방법으로 투석도관을 삽입한 16례의 의무기록을 바탕으로 복막투석관 삽입 후 첫 2개월간 투석도관의 누출, 폐쇄, 삽입 부위의 감염, 위치 이동 등 복막투석관 삽입과 관련된 합병증에 대해 후향적 분석을 시행하였다. 결과 : 고식적 수술을 받은 군(16례)에서 1례(6.3%)에서 수술 직후 심한 출혈로 재수술을 받았고, 복막액의 누출은 2례(12.5%) 있었으며, 보존적인 치료로 호전되었다. 삽입 부위 감염은 없었으나, 2례(12.5%)에서 복막염이 발생하였다. 투석도관의 이동으로 인한 기능부전이 3례 있었고 이중 2례에서 재수술을 받았으며, 1례는 보존적인 치료로 호전되었다. 복강경 수술을 받은 군(21례)에서 2례(9.5%)에서 투석액의 누출이 있었고, 보존적인 치료로 호전되었다. 삽입 부위의 감염은 없었고, 복막염이 2례(9.5%)에서 있었다. 1례에서 투석도관의 막힘이 있었고, 이 경우는 기존의 고식적 수술로 투석관 삽입 후 투석관 이동으로 재 삽입 후 불응성 복막염으로 투석관을 제거한 뒤 복강경 수술을 받은 증례였다. 투석도관의 이동은 없었다. 두 군의 합병증의 발생빈도는 통계적으로 유의한 차이는 없었다. 결론 : 본 연구에서 소아에서 복강경적 투석도관 삽입술을 시행한 경우, 1세 미만의 소아에서도 시술이 가능하였으며, 기존의 수술법에 비해 합병증이 증가하지 않았다. 또한 절개범위를 더 넓히지 않으면서도 장간막 절제 및 투석도관의 고정이 가능하여, 이를 통해 추후 투석도관의 이동이나 폐쇄의 위험요소를 줄일 수 있다는 장점이 있었다. 따라서 소아에서 복막투석도관 수술 시 복강경적 방법을 이용하는 것이 효율적인 복막 투석을 위해 유용하다고 생각된다. Purpose : To assess the early complication of laparoscopic peritoneal dialysis catheter implantation in children. Methods : Medical record review was carried out on 21 laparoscopic and 16 conventional peritoneal dialysis catheter implantations which were performed in 31 children under 18 years of age between 2002 and 2006. All medical records were retrospectively analyzed. The patients were followed until 2 months after catheter placement. Patient characteristics and catheterrelated complications, such as significant bleeding, leakage, obstruction, migration, insertion site infection and peritonitis during the first 60 days after implantation were recorded. Results : After conventional operation, dialysate leakage occurred in 2 of 16 cases and all cases improved after conservative management. In 1 case, significant bleeding occurred and re-operation was performed. Three cases of obstruction due to migration were reported, 2 cases underwent reoperation and 1 case improved without intervention. After laparoscopic surgery, outflow obstruction occurred in 1 out of 21 cases, which was caused by adhesion after several reinsertions of the catheter and recurrent peritonitis. No migration was noted after laparoscopic surgery. There was no significant difference in the complication rate between the two groups. Conclusion : Laparoscopic peritoneal dialysis catheter placement is feasible in children of all age groups, with at least equivalent functional results compared to conventional surgery. The additional advantage of laparoscopic catheter insertion is the option to identify and eliminate anatomical risk factors, such as intra-abdominal adhesions, and to perform partial omentectomy without additional incisions.

Objective: To evaluate the significance of the expression of HER-2/neu oncoprotein as a prognostic factor, we retrospectively examined its overexpression rates in epithelial ovarian cancer and their relationships with prognostic factors. Methods: Immunohistochemistry for Her-2/neu oncoprotein was performed on formalin-fixed, paraffin-embedded tissues from 45 epithelial ovarian cancer operated between 1999 and 2002. We analyzed relationships between the overexpression of HER-2/neu oncoprotein and prognostic factors including age, histologic type, surgical stage, residual tumor ≥2㎝, and recurrence. Results: The rate of overexpression of HER-2/neu oncoprotein in epithelial ovarian cancer was 31.1% (14/47). The overexpression of HER-2/neu oncoprotein showed associations with residual tumor ≥2㎝ (p=0.049) and recurrence (p=0.029) in univariate analysis. But, there were no associations between the overexpression of HER-2/neu oncoprotein and overall survival. Conclusion: The overexpression of HER-2/neu oncoprotein was associated with residual tumor and recurrence in univariate analysis, but appeared to have no prognostic significance for overall survival of epithelial ovarian cancer. Further and larger prospective studies using multivariate analysis are necessary to establish the clinical applicability of these observations.

This research collected and organized the various materials about the economic effect of design and design strategies of major nations and cities. It aims to verify that aggressive investment in design is essential through demonstrating design as a core keyword to overcome the economic crisis in the era of worldwide recession. Namely, it confirms that design is a shortcut to overcome the economic crisis and a foundation for the new growth and economic take-off. There are many cases. England, receiver of the IMF loan at the end of 1970s, overcame the crisis through realization of the proposition, ``Design or Resign.`` With the leadership of Margaret Thatcher as a prime minister, England promoted Redesign project changing fundamental basis of the industry and restructuring enterprises and organizations. The great depression in 1930s was the period offering new anticipations to the designers. It also gave GM, who invested drastically to design, an opportunity to take the world market, while it gave Ford, who aimed at generally popular cars, a disappointment loosing the market. The more crisis it is, the more likely it is that design is important and emphasized. ``For revitalization of the economy, design is important`` by John Cotton Dana in 1928 and ``Design loves a Depression`` by Michael Channel in 2009 both stressed that design is important to economic recession. We developed the concept of DESIGNOMICS based on the idea that ``Design becomes more important in times of depression.`` Designomics is a compound word of design and economy emphasizing the economic aftereffect of design. The primary point of view of Designomics is that design has a great effect to economy, and especially in the period of depression there are many cases overcoming the economic crisis relying on design. Therefore, Designomics is used to highlight the necessity of design management and the significance of strategic approach as well as regular and continuous investment. Through the analysis of the historical and modern meaning of Designomics and the strategies of each country and city, we confirmed the great ripple effect of design and the necessity of design management. For example, an average period and expenses for the development of design can be reduced from 1/10 up to 1/20 comparing to that of technology. With that less effort, however, the research on the English enterprises shows that the company with more emphasis on design has the higher and stabler stock prices. It tells us that design facilitates the value and stability of the enterprise, and serves as a momentum to innovate the enterprise. Many companies practically channel to design based enterprise through continuous innovation of merchandises, production, management, organization, image, and etc. by design. It is same with the nation and the city. England, Japan, and USA all put a premium on design. Also rising nations are trying to control the world market through design innovation. Many cities develops symbol, revitalize underdeveloped areas, change the life of citizens, and nurturing art, contents as well as tourist by various design projects. In that Designomics of Seoul function as a principal strategy to overcome the recession by getting over the limit and at the same time building growth power of the future. To the current Seoul with the level of urban infrastructure in 10 thousand dollars in spite of the national income close to 20 thousand dollars, the recession can be the chance. Utilizing the recession, Seoul can channel to sustainably growing city by promoting the various design management improving the urban infrastructure and creating the brand and image of Seoul. Without the effort, Seoul will pay dear for the deteriorated urban environment. In that point, Designomics of Seoul is not an extravagant project wasting the taxes, but a project securing sustainable growth potentiality overcoming the worldwide recession.

정수정(Su Jeong Jeong),이창현(Chang Hyeon Lee),김현영(Hyun Young Kim),이상훈(Sang Hoon Lee),황인국(In Guk Hwang),신창섭(Chang Seob Shin),이준수(Junsoo Lee),정헌상(Heon Sang Jeong) 한국식품영양과학회 2012 한국식품영양과학회지 Vol.41 No.1

자작나무수액의 채취시기에 따른 성분 변화를 분석한 결과 갈변도와 탁도는 수액 채취시기가 늦어질수록 증가하여 각각 0.076~0.222 및 0.048~0.138의 범위를 나타내었으며, pH는 채취 후반부로 갈수록 감소하였으며, 총산도는 증가하였다. Citric acid는 채취 초기에는 검출되지 않았으나 후반기에 미량 검출되었고 malic acid는 채취 후반기로 갈수록 점차적으로 증가하였다. Glucose는 0.497~0.664%의 범위에서 증가하였다가 감소하였고, fructose는 0.364~0.433% 범위에서 채취 후반기로 갈수록 증가하였다. 조단백질 함량은 3.40~32.37 mg%의 범위에서 채취시기 후반기에 크게 증가하는 경향을 보였으며, 조회분은 0.01~0.04% 범위에서 수액 채취 후반기로 갈수록 증가하였다. 무기성분으로는 Cu, Fe, Ca, Mg, Mn 및 K이 검출되었고 채취 후반기로 갈수록 증가하였으며, 그중 K는 5.25~37.27 mg/L의 범위에서 채취 후반기에 크게 증가하였다. 이상의 결과는 당류와 무기성분 및 단백질 등의 각종 성분이 함유된 자작나무수액을 이용한 기능성 소재 및 가공식품의 개발에 기초자료로 제공될 수 있을 것이며, 채취 후반기의 수액은 갈변도 및 탁도의 증가로 음용하기에 문제가 있지만, 영양성분의 증가로 인하여 영양적으로 우수할 것으로 판단되므로 수액의 품질을 일정하게 유지하기 위한 적절한 가공법이 적용된다면 자작나무 수액의 이용률 향상에 도움이 될 것으로 판단된다. This study evaluated the quality characteristics of white birch (Betula platyphylla var. japonica) sap with different collection times. The changes of browning index, turbidity, pH, total acidity, organic acid, free sugar, crude protein, crude ash, and mineral content were investigated. The browning index and turbidity increased from 0.076 to 0.222 and from 0.048 to 0.138, respectively, with increasing collection time. The pH decreased from 6.09 to 4.72, while total acidity increased with increasing collection time. Citric and malic acids were detected and malic acid increased with increasing collection time. Glucose and fructose as free sugars were detected and their contents were 0.364~0.433% and 0.497~0.664%, respectively. Crude protein and crude ash contents remarkably increased from 3.40 to 32.37 mg% and from 0.01% to 0.04%, respectively, with increasing collection time. Cu, Fe, Ca, Mg, Mn, and K were detected, and increased with increasing collection time. Particularly, K increased remarkably from 5.25 to 37.27 mg/L over time. These results indicate that the optimum processing method to improve the quality of white birch sap is necessary, because the quality of sap decreased as collection time increased, but nutritional value increased.

This study examined existing research on Hanyang, specifically its T-shaped road structure. The focus was on the formation and role of intersections in Hanyang, particularly in the district boundaries of Hanseongbu 5. This study explored the possibility that, during the early planning stages, a north-south axis connected the Sejong-daero intersection and Gyeongbokgung Palace with Namdaemun. The Bell Tower Intersection emerged as a crucial transportation hub and the center of Hanyang, linking Jongno, Namdaemun-ro, and Jeondong-ro. Analysis of old maps and literature confirmed the presence of crossroads throughout Hanyang, with Sageori serving as the name for administrative districts. These intersections held significance for both security management and military purposes, making the Bell Tower Cross a representative element of Hanyangs urban landscape during the late Joseon Dynasty.
