Objectives: The aim of this study was to investigate the correlation between fatigue degree and Comprehensive diagnosis of Qui Xui Shui in patients with functional dyspepsia. There again, we investigated an association between scores obtained from Comprehensive diagnosis of Qui Xui Shui and state of skin sympathetic tone or cardiovascular reactivity. Methods: Subjects were 56 patients with Functional dyspepsia and 8 healthy People. Fatigue degree was assessed by questionnaires consisting of subjective complaints of fatigue. Comprehensive diagnoais of Qui Xue Shui was investigated by questionnaire and physical examination, total score and composition score were calculated from the symptom score. Skin sympathetic tone was measured by Ryodoraku Score(RS) and Cardiovascular Reactivity(CV Reactivity) was checked by Pulse diagnostic apparatus. All patients were divided into two groups by RS $40{\mu}A$(below and above) or by CV Reactivity(decreased and increased or not decreased). Results: There was highly significant correlation between Fatigue Degree and total score and each composition score of Comprehensive diagnosis of Qui Xui Shui. And total score of patients was significantly higher than that of health controls : in the patients, females than males. Significance related with the level of RS $40{\mu}Aor$ the state of CV Reactivity were not remarkable in both patients and health control group. Conclusions: Fatigue degree seems to have a special feature reflecting the state of Comprehensive Diagnosis of Qui Xui Shui in patients with functional dyspepsia.

Streptomces sp. MET 0515의 균체외 Alginate lyase의 정제 및 특성
김현경,이재창,강남현,김송희,김종국,정기철,Kim, Hyun-Kyoung,Lee, Jae-Chang,Kang, Nam-Hyun,Kim, Song-Hee,Kim, Jong-Guk,Chung, Ki-Chul Korean Society of Life Science 2007 생명과학회지 Vol.17 No.5
알긴산분해효소(EC 4. 2. 2. 3)를 균체외로 생산하는 새로운 방선균을 전라남도 완도의 연안토양으로부터 분리하고 이 균주를 Streptomyces sp. MET 0515라 명명하였다. 이 균주가 생산하는 균체외 알긴산분해효소를 아세톤 침전, 음이온 교환 크로마토그래피(Q-Sepharose and DEAE-Sepharose), 젤 크로마토그래피(Sephacryl S-200 HR gel filtration chromatography)를 이용하여 정제하였다. 이 효소의 최적 활성 온도과 pH는 각각 $70^{\circ}C$와 pH 7.5이고, 온도 안정성은 $0-50^{\circ}C$, pH 안정성은 pH 6.0-9.0였다. 이 효소는 $Mn^{2+}$ 이온 첨가시에는 활성이 증가하였으며 1mM $Fe^{3+}$, 1mM EDTA, 1mM $Zn^{2+}$ 이온 첨가시에는 활성이 억제되었다. 또한 이 효소는 poly-alpha 1,4-L-guluronate와 poly-beta 1,4-D-mannuronate두 종류의 기질에 대하여 활성을 나타냈다. 따라서 본 효소는 다른 미생물 기원의 효소와 비교해 볼 때 Streptomyces sp.가 생산하는 첫번째 효소로 인정되었다. We isolated a new extracellular alginate lyase-producing microorganism, which displayed alginate-depolymerizing activity in plate assays, from coastal soils in Wando, Jeollanam-do, Korea. This alginate-depolymerizing bacterium belonged to the genus Streptomyces and it was named Streptomyces sp. MET 0515. An extracellular alginate lyase(ALY1) secreted by Streptomyces sp. MET 0515, was purified to homogeneity by a combination of acetone precipitation, anion-exchange chromatography (Q-Sepharose and DEAE-Sepharose) and Sephacryl S-200 HR gel filtration chromatography. Its molecular mass was 26 kDa as determined by SDS-PACE analysis. The enzyme had an optimal temperature of $70^{\circ}C$ for its activity, and was most active at pH 7.5. The thermal and pH stability were $0-50^{\circ}C$, and pH 6.0-9.0, respectively. The enzyme activity was stimulated by 1mM $Mn^{2+}$, and inhibited by 1mM $Fe^{3+}$, 1mM EDTA and 1mM $Zn^{2+}$. Preliminary analysis of substrate specificity showed that this alginate lyase had activity on both poly-alpha 1,4-L-guluronate and poly-beta 1,4-D-mannuronate in the alginate molecule.

김현경,남은미,이경은,이순남,Kim, Hyun-Kyung,Nam, Eun-Mi,Lee, Kyoung-Eun,Lee, Soon-Nam 한국호스피스완화의료학회 2012 한국호스피스.완화의료학회지 Vol.15 No.1
목적: 우리나라에서는 의과대학에서 말기환자 돌봄에 대한 교육이 충분치 못하다. 이 연구는 의과대학생에서 말기환자 돌봄 교육이 학생들의 말기환자의 돌봄에 관한 인식과 태도에 미치는 영향을 평가하고 교육에 대한 요구도를 파악하고자 하였다. 방법: 이화여자대학교 의학전문대학원 의학과 4학년 학생 166명을 대상으로 말기환자의 호스피스 완화의료에 관한 설문조사를 교육 전과 후에 조사하여 분석하였다. 결과: 사전의료의향서 작성시기에 관한 질문에 교육 전에는 '임종이 가까운 말기'가 33.6%로 가장 빈도가 높았으나 교육 후에는 '건강할 때'가 58.7%로 가장 많았다. 무의미한 연명치료의 유보나 중지에 관하여는 수업 전과 후에 심폐소생술은 48.1% 대 92.5%, 기관삽관이나 인공호흡기 38.3% 대 92.5%, 혈압상승제 39.1% 대 85.8%, 혈액투석 60.9% 대 94.8%, 총정맥영양공급 27.8% 대 56.0%로 유의한 변화를 보였다. 안락사에 대한 반대 의사는 46.6%에서 82.1%로 현저히 증가하였다. 모든 학생이 말기환자 돌봄 교육이 필요하다고 동의하였다. 결론: 대부분의 의과대학생은 임종환자관리 교육과정을 통해 죽음의 의미에 대해 성찰하는 시간을 갖고 말기환자의 호스피스 완화의료 교육의 필요성을 인식하였다. 또한 말기환자의 돌봄에 관한 인식과 태도의 변화가 컸다. 향후 이러한 교육과정이 모든 의과대학에서 정규교육과정으로 포함되어야 할 것이다. Purposes: Most medical schools in Korea do not provide adequate education in end-of-life care. This study was designed to illustrate the need to improve end-of-life care education and to assess the effect of the education on fourth-year medical students' awareness and attitude towards hospice and palliative care for terminally ill patients. Methods: One hundred sixty six fourth-year medical students were surveyed with questionnaires on end-of-life care before and after they received the education. Results: Before receiving the education, students most frequently answered "at the end of life" (33.6%) was appropriate time to write an advance medical directive. After the education, the most frequent answer was "in healthy status" (58.7%). More students agreed to withholding or withdrawing futile life-sustaining treatment increased after the education (48.1% vs. 92.5% (P<0.001) for cardiopulmonary resuscitation, 38.3% vs. 92.5% (P<0.001) for intubation and mechanical ventilation, 39.1% vs. 85.8% (P<0.001) for inotropics, 60.9% vs. 94.8% (P<0.001) for dialysis and 27.8% vs. 56.0% (P<0.001) for total parenteral nutrition). Significantly more students opposed euthanasia after the education (46.6% vs. 82.1%, P<0.001). All students agreed to the need for education in end-of-life care. Conclusion: After reflecting on the meaning of death through the end-of-life care education, most students recognized the need for the education. The education brought remarkable changes in students' awareness and attitude towards patients at the end of life. We suggest end-of-life care education should be included in the regular curriculum of all medical schools in Korea.

In 2020, Yi Hunwoo was discovered as one of the earliest modern architects in Korea. However, his personal life was yet mostly unknown, including the time of his death. The research team ('the team' hereafter) searched for the records of his personal life and professional career. First, his family genealogical chart revealed that he died in 1937. Having located and contacted Yi's direct descendents, the team was able to clarify his family background with the descendants' testimonies. They possess the photographs of him and his family members, including Yi's picture when he was a freshman at the Nagoya Higher Technical School in Japan. The team also identifies his birthplace and the location of his grave as Hadong, Gyeongsangnamdo, Korea. The team visited his project site in Jinju, Gyeonsangnamdo, Korea and obtained more detailed information about the Ilshin Girls' High School, which he designed in 1928. Gyohoan, the congregation records of Cheondogyo, one of the leading religions in Korea during Yi's times, confirmed that he was one of the congregation members. The field research also discovered the house he designed and built in his hometown of Hadong, probably the only surviving architectural project by him. This paper is to report the result of the research on Yi's life and career with the aim of providing materials for further studies in identifying and positioning him more properly in the early 20th century Korean architectural scene.

홍삼함유 과채류 복합 추출물의 증숙열처리 및 유산균 발효에 의한 장관면역 활성
김현경,Kim, Hyun Kyoung 국제문화기술진흥원 2022 The Journal of the Convergence on Culture Technolo Vol.8 No.6
본 연구의 목적은 과채류 복합추출물에 소량의 홍삼을 첨가하여 증숙가열 및 유산균 발효에 의한 진세노사이드 대사산물의 활성 증가와 장내면역 활성이 현저히 개선되는지를 알아보고자 하였다. 홍삼 단독 추출물 또는 과채류복합추출물에 비해 홍삼을 함유한 과채류 복합추출물에서 시너지 효과에 의한 장내면역 활성의 증가가 관찰됨을 확인하였다. 다음으로 홍삼을 함량별로 첨가하여 유산균 발효에 따른 시너지 효과를 얻을 수 있는 홍삼의 농도를 결정하였다. 그 결과, 홍삼을 과채류 혼합물 질량에 대하여 3~10%의 질량비로 혼합하여 증숙 및 유산균 발효 추출하였을 때 시너지 효과가 나타나는 것을 확인하였다. 또한 홍삼을 함유한 과채류 복합추출물은 200㎍/ml의 농도로 처리하였을 때 홍삼이 함유되지 않은 과채류 복합추출물에 비해 NO 생성을 약 60% 억제하였으며, IL-1β의 발현은 63%, IL-6의 발현 69%, TNF-α의 발현 76% 수준으로 억제하여 장내면역 활성이 크게 향상되었음을 확인하였다.
