This study surveyed the selection attributes and degree of satisfaction among Japanese restaurant customers by conducting frequency analysis on the data. Among all types of Japanese restaurants customers selected sushi bars the most (48.2%), and they considered taste (73.9%), price (34.8%), and service (22.2%) to be very important. When eating at Japanese restaurants, satisfaction differences among sanitation (p<0.05), price (p<0.05), and unique design (p<0.1) each had a significant difference with F values of 3.313, 3.208, and 2,702, respectively. factor analysis of the effect of selection attributes on Japanese restaurant performance revealed three factors; image, service, and food. Their combined satisfaction was 61.41%, and each of these three factors showed a Cronbach's ${\alpha}$ value of 0.744, 0.739, and 0.623 in the reliability analysis, respectively, thus demonstrating the overall level of reliability. Multiple regression analysis showed that increased overall satisfaction of Japanese food was related to the satisfaction levels of food and service, and not to that of surrounding satisfaction.

최근 많은 기업들이 개개인의 인적자원을 기업 가치 창출의 핵심 자산으로 인식하고, 기업 경쟁력 강화를 위하여 역량기반의 인적자원관리 및 인재육성에 많은 노력을 기울이고 있다. 국내 건설업에서 큰 비중을 차지하고 있는 종합건설회사의 건설기술자는 건설 프로젝트 생애주기의 각 단계에서 다양한 참여주체와 함께 공사관리 업무를 수행하며, 건설기술자의 역량은 건설공사의 성패에 직접적인 영향을 미치는 중요한 요소이다. 하지만 현재 국내의 건설기술자 능력 평가 방식은 자격 위주의 평가로서 실제 공사관리 업무에 대한 소화능력과는 거리가 있다. 이와 같은 관점에서 본 연구는 건설업의 기본관리 항목 중 하나인 원가관리의 업무 프로세스 및 세부 수행항목을 분석하여 원가관리 업무 숙련도 수준을 제시하였고, 이를 바탕으로 건설기술자 직급별 요구역량 대비 현 수준 분석 및 업무 단계별 건설기술자 업무역량 분석을 실시하여 시사점을 도출하였다. Recently, many companies recognize the individual human resource as a core asset of the corporate value creation and devote a lot of effort to develop and manage competency-based human resource in order to strengthen the corporate competitiveness. As the integrated construction company taking the major portion in Korean construction industry, its construction engineers perform the construction supervision task with various related parties at each stage of the life cycle of the construction project. Therefore, the competency of a construction engineer is an important factor which have a direct impact on the success of the construction project. However, the current capability evaluation scheme of the domestic construction engineers is mainly oriented on the qualification factors such as the certificates or the seniority and this is quite different from evaluating the actual ability for construction management tasks. In this point of view, this study proposes the appropriate level of proficiency in cost management by analyzing the work process and its detailed items of the cost management that is the one of the basic management items of the construction industry. Based on this, this study analyzes the current competency level of the construction engineer by comparing with the required competency of each job position and also performs the engineer's work competency analysis of each work step.

The optimum condition for phenolics contents extraction from purple sweet potato was 12 hrs. in 50% ethanol. The electron donating scavenging activities (DPPH), ABTS radical cation decolorization (ABTS) and antioxidant protection factor (PF) of Jami, Yeonjami and Shinjami were higher than general sweet potato, and thiobarbituric acid reaction substance (TBARs) was below 30%. The minimum inhibitory concentration (MIC) against Staphylococcus aureus and Escherichia coli on skin were each 5,000 and 2,500 ppm in all purple sweet potatoes, and MIC of Jami was the lowest as 2,500 ppm against Staphlococcus epidermidis. The whitening (tyrosinase inhibitory) activity of purple sweet potatoes was the highest as 62.5% and 48.7% in Jami water and ethanol extracts. The anti-inflammation (hyaluronidase inhibitory) activity of purple sweet potatoes was the highest as 25.3% and 94.4% in Jami water and ethanol extracts. The safety of cosmetic with Jami extracts was assessed by various safety profiles. pH and viscosity change of essence for 90 days was not detected. Cosmetic was stable to temperature and light for 90 days. The result to measure changes of skin color and pore size of the skin was that an aged skin was more effective than young skin.

가와사키병은 다른 원인이 없는 발열과 함께 피부점막에 특징적인 병변을 보이는, 소아에서는 비교적 흔한 질환으로 일반적으로 급성기에는 혈역학적으로 안정적이다. 저자들은 심한 저혈압과 함께 급성 신손상이 있는 상태에서 내원한 8세 남아가 치료 중에 가와사키병으로 진단된 증례를 경험하였다. 최근에는 가와사키병 초기에 불안정한 혈역학적 상태를 가와사키병 쇼크증후군이라는 개념으로 정의하고 있다. 환아는 면역글로불린 치료 후 임상적으로 회복되었으나 관상동맥 확장 합병증이 확인되어 아스피린을 복용하고 있으며, 가와사키병의 합병증으로서는 비교적 드문 고혈압이 확인되어 베타 차단제를 사용하고 있다. 본 증례를 통해 가와사키병 쇼크증후군의 임상 양상을 알고, 혈관염이라는 가와사키병의 특성을 고려해볼 때 혈압 모니터링의 중요성을 깨닫게 되었다. Kawasaki disease (KD) is an acute febrile mucocutaneous lymph node syndrome that commonly presents with stable hemodynamic status during the acute phase. An 8-year-old boy initially presented with severe hypotension and acute kidney injury. He was placed in the intensive care unit and was diagnosed with KD. Observed clinical features were defined as KD shock syndrome. His coronary artery was dilated during the subacute phase. Furthermore, he was given anti-hypertensive medications, owing to hypertension as an unusual complication of KD. We knew the importance of monitoring for blood pressure considering vasculitis as an aspect of the main pathogenesis of KD.

건천마와 발효천마의 추출물을 이용하여 항노화 활성과 신경성장인자 유도효과를 비교하였다. 항산화 활성을 비교하여 측정한 결과 모든 추출물에서 비교적 높은 항산화력을 나타내었으며, 발효하지 않은 건천마 추출물보다 발효과정을 거친 발효천마 추출물에서 다소 높은 항산화력을 나타내었다. Angiotensin converting enzyme(ACE)와 xanthine oxidase(XOase) 저해 활성을 측정한 결과 DW 추출에서 DPPH가 건천마 64.14 ± 0.89%, 발효천마 66.21 ± 1.03%으로 나타났고, ABTS가 건천마 54.15 ± 1.37%, 발효천마 60.24 ± 2.25%로 나타났다. 70% EtOH추출에서도 유사한 결과를 보여 발효천마 추출물이 ACE에 대해 높은 저해활성을 나타내었으나, XOase에 대하여 발효 및 건천마 추출물의 차이는 크지 않다는 것을 알 수 있다. 그리고 nerve growth factor(NGF) 활성 측정 결과 모든 추출물에서 40%의 신경돌기 성장효과를 나타내었다. 이와 같이 건천마와 발효천마의 추출물을 상대로 천마의 항노화 활성과 신경성장인자 유도효과에 대한 기능성을 탐색한 결과 발효천마가 건천마보다 우수한 생리기능성을 가지는 것을 알 수 있어, 발효과정을 통하면 천마의 활용도를 높일 수 있다는 것을 증명할 수 있었다. This study was performed to examine the increasing biological activities of both nerve growth factor induction and anti-aging activity of gastrodia (Gastrodia elata) with fermentation process. Antioxidant activities, taken in the fermenting, were investigated to verify utility value of gastrodia for functional food and cosmetics. Fermented gastrodia extracts showed higher antioxidant activities than dried gastrodia extracts. During the routine check of all the practical use potential as functional food, inhibition effect of angiotensin converting enzyme (ACE) and xanthine oxidase (XOase) was tested among water extracted dried gastrodia (WEDG), water extracted fermented gastrodia (WEFG), 70% ethanol extracted dried gastrodia (EEDG) and 70% ethanol extracted fermented gastrodia (EEFG). DPPH was shown as WEDG = 64.14 ± 0.89%, WEFG = 66.21 ± 1.03%, EEDG = 82.25 ± 0.52%, and EEFG = 82.36 ± 2.37%. ABTS was shown as WEDG = 54.15 ± 1.37%, WEFG = 60.24 ± 2.25%, EEDG = 59.18 ± 1.86%, and EEFG = 77.17 ± 4.23%. Therefore, ACE activity was dramatically inhibited by EERG while there was no difference of XOase inhibition between EEFG and EERG. Nerve growth factor (NGF) activity was measured and indicated about 40% increased neurite growth effect. To conclude, biologically active compounds of gastrodia were increased by fermentation process. It seems to be that ferment gastrodia enhance the use ranges from functional food to fuctional cosmetics, and to all processing industry.

목적: 제주도에 거주하는 뇌전증 진단을 받은 소아 환자들을 대상으로 항경련제 치료 종결 후 발작의 재발에 영향을 미치는 예측 인자를 살펴보고자 하였다. 방법: 2001년 3월부터 2013년 5월까지 첫 발작으로 제주대학교 병원을 방문한 환자들을 연구 대상으로 하였다. 뇌자기공명영상이 정상이면서 마지막 경련으로부터 2년 이상 경과하고 치료 종결시 뇌파가 정상인 환아들을 최종 연구 대상으로 하였다. 그리고 최소 관찰 기간 1년 이상인 경우로 제한하였다. 결과: 재발은 전체 68명 중 23명에서 발생하여 치료 종결 후 1년 완치 비율은 66.2%였다. 치료 종결 후 재발 환자들의 평균 재발 간격은 6.9±7.1개월이었다. 누적으로 계산시 항경련제 중단 도중 4명, 3개월 이내 16.2% (11/68), 6개월 이내 19.1% (13/68), 1년 이내 86.9% (20/23), 19개월 1명, 22개월 1명, 24개월 1명으로 대부분의 재발은 1년 이내에 발생하였고 모든 환자는 2년 이내에 재발하였다. 재발에 영향을 미치는 인자에 대한 단변량 분석에서 10세 이상에서 첫 발작 발생(P=0.007), 후기 관해(P=0.020), 2년 이상 항경련제 치료(P=0.018), 복합열성발작(P=0.001)이 통계학적으로 의미있게 재발군에서 높은 빈도로 나타났다. 뇌전증 가족력(P=0.068)은 경계선상의 통계학적인 의미를 보였다. 다변량 분석 결과, 복합열성발작(P=0.009, odds ratio= 24.2, 95% CI 2.23-262.28), 10세 이상 첫 발작 발생(P=0.002, odds ratio=16.7, 95% CI 2.76-101.31), 후기 관해(P=0.047, odds ratio=4.4, 95% CI 1.02-18.93)에서 뇌전증 환자의 치료 종결 후 재발에 영향을 미치는 인자로 확인되었다. 결론: 복합열성발작, 10세 이상 첫 발작 발생, 항경련제 치료 후 12개월 이내 경련 조절 실패에 해당하는 변수가 뇌전증 환자의 치료 종결 후 재발에 영향을 미치는 독립 인자로 확인되었다. Purpose: We evaluated the risk factors for relapse of unprovoked seizures after drug withdrawal in epileptic children in Jeju Island, South Korea. Methods: A population-based retrospective study was performed in 632 children whose first unprovoked seizure occurred between March 2001 and May 2013. The study included children experiencing a seizure free-state during a minimum of 2- year treatment period with anti-epileptic drugs (AEDs) with at least 1-year follow-up after AED withdrawal at the Pediatric Department at the Jeju National University Hospital. Results: Sixty-eight children including 36 boys and 32 girls, met the above-mentioned inclusion criteria, and subsequent seizure relapse occurred in 23 patients (33.8%). The mean age at the first unprovoked seizure was 79.1±45.9 months and the mean number of unprovoked seizures was 7.1±4.9. Partial and generalized seizures were observed in 19 and 49 patients, respectively. Several variables such as the age at onset of the first seizure, late remission, duration of AED treatment longer than 2 years, and complex febrile seizures before the first unprovoked seizure affected the risk for relapse. Multivariate analysis identified complex febrile seizure, age at the first seizure onset being more than 10 years, and late remission as significant predictors of relapse. Conclusion: We identified three independent risk factors for relapse following an unprovoked seizure in epileptic children after AED withdrawal : complex febrile seizure, age at the first seizure onset being more than 10 years, and late remission.

N/A Backgroud: Gastric cancer remains the main cause of cancer-related death in Korea. Accurate preoperative staging of gastric cancer is essential to predict prognosis and to plan optimal treatment. Although there are many reports dealing with the diagnostic values of conventional methods, controversies are still present especially in the field of preoperative staging. In this study, we evaluated the accuracy of gastroscopy and upper gastrointestinal series(UGI) for diagnosis of gastric cancer, and determined the usefulness of ultrasonography and computed tomography for preoperative staging. Methods : One hundred twenty-three patients, who underwent operation from Aug. 1991 to Mar. 1995 under the diagnosis of gastric cancer were analyzed. We excluded 15 patients because their postoperative definitive stagings were undetemined. Results : 1) Among 123 patients, the proportion of early gastric cancer was 26.0%(32/123) and that of the advanced gastric cancer was 74.0%(91/123). 2) The sensitivity of endoscopic diagnosis of gastric cancer was 96.7%(119/123), and the accuracy to determine the depth of invasion was 82.9% (102/123). 3) The sensitivity of UGI study for gastric cancer was 89.9%(98/109), and the accuracy to determine the depth of invasion was 61.5%(61/109). 4) The sensitivity of abdominal ultrasonography to detect the tumor was 11.3%(8/71), the accuracy to determine the T stage was 29.2%(28/96), and the sensitivity and specificity to detect lymph node metastasis was 13.6%(8/59), 100%(37/37), respectively. 5) The sensitivity of abdominal CT to detect the tumor was 74.3%(26/35), the accuracy to determine the T stage was 32.5%(13/40), and the sensitivity and specificity to detect lymph node metastasis were 34.5%(9/29), 72.7%(8/11), respectively. 6) The accuracy of preoperative staging was 45.5%(56/123). The 49.6%(62/123) of gastric cancer was downstaged, whereas only 4.1%(5/123) was overstaged. Conclusion: Our results show that high accuracy for diagnosis of gastrie cancer with the gastroscopy and UGI. However preoperative staging with ultrasonography and computed tomograpy was often underestimated, which could be concluded that the usefulness of the radiologic methods was limited.

최재홍 ( Jae Hong Choi ),최수한 ( Soo-han Choi ),김도현 ( Do-hyun Kim ),최용성 ( Yong-sung Choi ),윤기욱 ( Ki Wook Yun ) 대한소아감염학회 2022 Pediatric Infection and Vaccine Vol.29 No.3

장기화된 코로나19의 유행으로 많은 임산부들이 분만에 임박하여 감염되는 사례들이 많아진 반면, 이런 상황에서 출생하는 신생아들을 처치 및 검사에 대한 국내 권고 사항은 코로나19 유행 초기에 만들어져 진료 현장에서 어려움이 많았다. 다행히 최근에 축적된 자료와 외국의 최신 지침을 반영한 국내 권고 사항이 개정 발표되어 이를 소개하게 되었다. 대표적인 변화로는 코로나19 확진 산모에게 출생한 신생아의 처치 및 검사가 반드시 음압 격리 시설 내에서 이루어질 필요 없이 적절한 보호장구를 착용한 상태에서 신생아실에서 이루어질 수 있도록 하였다. 또한 코로나19 검사도 생후 48-72시간에 1회 시행할 것을 권고하였으며, 모자 동실을 할 경우에는 증상 없는 건강한 신생아라면 검사 없이 경과 관찰할 수 있도록 하였다. 입원이 필요한 경우에는 기존 권고 사항과 같이 생후 24시간, 48시간 째에 각각 두 번 검사를 시행하도록 하였다. 개정된 권고 사항이 코로나19 확진 산모와 신생아의 진료에 유연성을 주면서 감염의 확산을 최소화할 수 있으리라 기대한다. For the extended duration of the coronavirus disease 2019 (COVID-19) pandemic, reports emerged that mother-to-child transmission rates were low. However, the pandemic protocols including strict isolation, testing for severe acute respiratory syndrome coronavirus 2, and negative pressure isolation remained in Korea. Recently, the guideline for the management of neonates born to mothers with COVID-19 have been revised based on guidelines in other countries. Here, we introduce this newly developed guideline and review the foreign guidelines that were used for reference.

김은미,최재홍,Kim, Eun-Mi,Choi, Jae-Hong 한국섬유공학회 2008 한국섬유공학회지 Vol.45 No.4

The dyeing characteristics and fastness of rayon-mimetic (RMM) fiber were examined with some commercial disperse dyes compared to those of poly(ethylene terephthalate) fiber. Similar exhaustion yields were achieved at $120^{\circ}C$ to $130^{\circ}C$ which ranged from 90% to 99%. Critical adsorption range of disperse dyes on RMM fiber was lower than regular PET fiber about $10^{\circ}C$. Exhaustion was saturated at 2% owf dye concentration. Color fastness of RMM was similar to those of PET dyeings including fastness to wash, rubbing and light.
