  • This is a pilot study to survey the general demand of senior-assistive necessities before a standardization system for senior-assistive necessities is developed as well as to describe health professionals' opinions about the demand and quality of Oriental medical aids and necessities for daily living for the elderly. This is a descriptive survey in which 29 health professionals are questioned, using structured questionnaires based on ISO 9999. The questionnaires were developed by 7 expert conduction standardization system of senior-assistive products in Korea. The data is analyzed by descriptive statistics. The result is as follows : First, with regard to the demand for all of the items in Oriental medical aids for the elderly, the demand of cupping glasses is the highest, followed by instrument used to apply heat treatment, massage equipment, thermo-therapeutic mattress, and heat or ice packs. With regard to the demand for all of the items for the necessities for daily living for the elderly, chairs are the highest, followed by rolling chairs, beds for health, and heigh adjustable beds. Second, with regard to quality of Oriental medical aids, ${\ulcorner}$aids for hair care${\lrcorner}$ are the best, whereas ${\ulcorner}$aids for boiling Oriental medicine${\lrcorner}$ are the worst. In quality of the necessities for daily living, ${\ulcorner}$chairs${\lrcorner}$ are the best, whereas ${\ulcorner}$beds${\lrcorner}$ are the worst. Above all, this result shows that with ${\ulcorner}$aids for heat or cold treatment${\lrcorner}$, there is relatively high demand and low quaily of Oriental medical aids, and with ${\ulcorner}$Beds${\lrcorner}$, there is relatively high demand and low quality. Therefore, aids for heat or cold treatment and beds in th necessities for daily living are required to be developed for standardization of senior-assistive necessities.

  • Background: Ginsenosides are known as the principal pharmacological active constituents in Panax medicinal plants such as Asian ginseng, American ginseng, and Notoginseng. Some ginsenosides, especially the 20(R) isomers, are found in trace amounts in natural sources and are difficult to chemically synthesize. The present study provides an approach to produce such trace ginsenosides applying biotransformation through Escherichia coli modified with relevant genes. Methods: Seven uridine diphosphate glycosyltransferase (UGT) genes originating from Panax notoginseng, Medicago sativa, and Bacillus subtilis were synthesized or cloned and constructed into pETM6, an ePathBrick vector, which were then introduced into E. coli BL21star (DE3) separately. 20(R)-Protopanaxadiol (PPD), 20(R)-protopanaxatriol (PPT), and 20(R)-type ginsenosides were used as substrates for biotransformation with recombinant E. coli modified with those UGT genes. Results: E. coli engineered with $GT95^{syn}$ selectively transfers a glucose moiety to the C20 hydroxyl of 20(R)-PPD and 20(R)-PPT to produce 20(R)-CK and 20(R)-F1, respectively. GTK1- and GTC1-modified E. coli glycosylated the C3-OH of 20(R)-PPD to form 20(R)-Rh2. Moreover, E. coli containing $p2GT95^{syn}K1$, a recreated two-step glycosylation pathway via the ePathBrich, implemented the successive glycosylation at C20-OH and C3-OH of 20(R)-PPD and yielded 20(R)-F2 in the biotransformation broth. Conclusion: This study demonstrates that rare 20(R)-ginsenosides can be produced through E. coli engineered with UTG genes.

  • 군에서 사용하는 무기체계의 경우 경제적이고 효율적인 조달·관리 및 유지를 위하여 국방규격을 제정하여 관리한다. 국방규격은 제품 및 용역에 대한 기술적인 요구사항과 요구필요조건의 일치성 여부를 판단하기 위한 절차와 방법을 서술한 문서로, 작성된 국방규격은 무기체계의 생산, 품질보증, 형상관리 등에 활용된다. 소프트웨어도 국방규격의 하나로 다른 국방규격(국방규격서, 품질보증요구서, 도면, 부품/BOM 목록)과 같이 작성되고 관리되나, 소프트웨어의 일부(또는 전부)를 포함하지 않고 규격화를 수행하는 경우가 있다. 이 경우 개발업체를 제외하고는 다른 업체들은 제품을 생산할 수 없어 경쟁계약이 제약될 뿐만 아니라, 승인 없이 업체가 임의로 소프트웨어를 변경할 수 있어 무기체계의 품질에도 큰 영향을 미친다. 따라서 소프트웨어의 규격화 누락 여부의 검증은 반드시 필요하나, 하드웨어 내부에 탑재되는 펌웨어의 경우 개발업체 외에는 규격화 누락 여부의 확인이 매우 어렵다. 본 연구에서는 실제 품질보증 업무 수행 시에 활용할 수 있는 소프트웨어 규격화 누락 여부의 검증 방안을 제시하였으며, 이를 통해 무기체계의 효율적인 생산, 품질보증에 기여할 것이다.

  • 컴퓨터에 전자적 형태로 저장된 의무기록인 EMR의 표준화에 대한 논의가 활발하다. 이는 EMR 표준화를 통해 의료 서비스의 향상을 기대할 수 있을 뿐만 아니라, 의료와 IT의 융합영역인 의료 빅데이터의 가치가 점차 높아지고 있기 때문이다. EMR 표준화와 관련한 주요 이슈 중 하나는 EMR 표준화의 필요성과 효과성을 이해관계자들에게 설득시키는 일이다. 연구자는 EMR 표준화에 대한 의사들의 인식을 기술 관점과 경제적 관점에서 살펴보고자 설문조사를 실시한 후 이에 대해 통계분석을 실시하였다. 실증분석 결과, EMR 시스템의 기능 품질과 경제적 가치는 EMR 표준화에 대한 유용성 인식과 수용 의도에 정(+)의 영향을 미치는 반면, 상호운용성은 유용성 인식에만 영향을 미치는 것으로 나타났다. 또한, 경제적 가치가 EMR 표준화 필요성에 대한 공감대 형성에 가장 중요한 변수로 확인되었다.

  • Background: Korean Hospital Standardization Program(KHSP), as a hospital accreditation program initiated and promoted by Korean Hospital Association since 1981, has played a key role in the hospital quality improvement in structural aspect particularly. Recently, however, KHSP has been critisized by hospitals and health personnels in that it is unpractical to be utilized as an initiative to improve hospital quality. In particular, the section of quality assurance in KHSP, strongly influenced by old version of Hospital Accreditation of Joint Commission in U.S.A., has been required to be fundamentally revised. For design of new criteria in quality assurance section, a survey for evaluation of existing program and collection of opinions for ideal one was conducted. Methods: For a month in 1994, structured questionnaires were administered by mailing to 470 hospital staffs from 200 hospitals, participated in the survey for the 1994 KHSP in each hospital. The total number of respondents was 116. Results: Less than half of the respondents(34.5%) value positively on the impact of current KHSP in general on the quality improvement of their hospitals. Moreover, most responses indicated that KHSP should be reorganized towards more practical and applicable one. Current KHSP criteria for quality activities in hospitals were regarded as a unpractical one which should be basically renewed. For new criteria and standards, most respondents emphasized the importance of applicability of those in real situations. Conclusion: For the KHSP to be effective, new evaluation criteria for quality activities should be more practical and fully accommodated to hospital situations in reality.
