        이수한,이인숙,이효정,유수인,김정은,김유진,박소훈,장경태,이민호 (사)한국조리학회 2022 한국조리학회지 Vol.28 No.3

        After COVID-19, healthy drinks, especially with taste and nutrition, has been increasing. This study intends to develop mixed juice using delicious Gold kiwi and nutritious Wa-song. The Gold kiwi and Wa-song were extracted in a weight ratio (a) of A (10:0), B (7:3), C (5:5), D (3:7), E (0:10) and volume ratio (b) of F (7:3), G (5:5), and H (3:7). There was no difference in pH according to the juice method, and the higher the mixing ratio of wa-songs, the higher it was. The sugar content was (a) Brix% in which mixed juice was higher than (b). The values for red was affected by the content of gold kiwi, and the values for yellow increased as the content of wa-song increased. The brightness decreased over time except for sample G. The higher the Gold kiwi content, the higher the DPPH radical scavenging activity, and the lower the IC50 value, the more showing higher radical scavenging ability. If you develop mixed juice, which is a sample B (7:3) of gold kiwi and wa-song (a), it will be excellent in quality and taste and effective in antioxidant. .

        공기압 실린더의 궤적 추적 제어를 위한 직접 적응제어

        이수한,장창훈,Lee, Su-Han,Jang, Chang-Hun 대한기계학회 2000 大韓機械學會論文集A Vol.24 No.12

        This study presents a direct adaptive controller which is derived by using Lyapunovs direct methods for trajectory tracking control of a pneumatic cylinder. The structure of the controller is very simple and computationally efficient because it does not use either the dynamic model or the parameter values of the pneumatic system. The bounded stability of the system is shown in the presence of the bounded unmodeled dynamics. The bounded size of tracking errors can be made arbitrarily small without giving andy influences on either input or output variables. The trajectory tracking performance and the stability of the control system is verified experimentally. The results of the experiments show that the proposed controller tracks the given trajectories, sine function and cycloidal function trajectories, more accurately than PD controller does, and it stabilizes the system and adaptive variables.

        지방정부 긴급재정관리제도의 적용 가능성 분석

        이수구(李修求) 한국지방정부학회 2019 지방정부연구 Vol.23 No.3

        본 연구에서는 파산제와 긴급재정관리제도의 개념을 살펴보고, 긴급재정관리제도가 작동될 가능성이 있는 유용한 제도인가의 여부를 검증하는데 초점을 두었다. 이를 위하여 선행연구와 정부자료를 토대로 지방재정위기관리제도의 6가지 지표를 활용한 분석모형을 수립하고 전국의 지방정부를 대상으로 재정건전성을 분석하였다. 분석결과 모든 지방정부들이 6개의 재정건전성 기준을 충족하고 있으므로 긴급재정관리제도가 적용될 가능성은 거의 없는 것으로 나타났다. 그리고 지방재정위기관리제도의 운영과정에서 6가지 재정건전성 지표의 상대적 중요성도 고려해야함을 발견할 수 있었다. 예산대비 채무비율과 채무상환비 비율이 가장 중요한 지표인 것으로 나타나 긴급재정관리제도의 핵심적 목표가 지방채의 관리에 있음을 시사하였다. 대안으로는 행정체제의 개편방향과 지방정부의 사무배분에 따른 재원배분체계를 수립할 필요가 있음을 제안했으며, 특히 보충성의 원리에 입각하여 지방정부의 재원확충에 우선순위를 두어야 할 것을 강조했다. 또한 중기적 재정상황을 예측할 수 있는 새로운 재정지표의 모색을 위한 후속적 연구의 필요성을 제안했다. This study focuses on examining the concept of the bankruptcy system and the Emergency Financial Management System and checking if the Emergency Financial Management System is a useful system that can work. For this, this study has established the six indicators for the Local Financial Crisis Management System based on the earlier studies and the Korean government data and analyzed the financial soundness of the local governments nationwide. The analysis shows that as all the local governments meet the financial soundness standard, there is no chance that the Emergency Financial Management System will be applied. Furthermore, the analysis finds out that the relative importance of the six financial soundness indicators have to be considered in operating the Local Financial Crisis Management System. The fact that the debt-to-budget ratio and the debt repayment ratio serve as the most important indicators suggests that the crucial objective of the Emergency Financial Management System lies in managing the local debts. As an alternative, it suggested that it is necessary to establish a financial allocation system according to the reorganization direction of the administrative system and the administrative affairs allocation of the local government. In particular, it emphasized that the priority should be placed on the expansion of the financial resources of the local government based on the principle of supplementation. In addition, it suggested the necessity of follow-up research to find new financial indicators that can predict mid-term financial situation.

        젖소 17두의 주목나무 독성 중독

        이수한,배춘식,정병현 한국임상수의학회 2003 한국임상수의학회지 Vol.20 No.3

        We found seventeen dairy cattle with the abnormal signs in cardiovascular and gastrointestinal systems after feeding of the yew foilage. Among them three cattle were dead due to yew poisoning. Among the remaining fourteen dairy cattle, four cattle showed similar symptoms as did dead cattle. Although the remaining ten dairy cattle did not show any abnormal signs, we conducted a therapy of forced magnesium sulfate infusion because the yew consumption might have been occurred in all cattle. As a result of the therapy, we could not found further signs of yew poisoning. The performance of the therapy and the treatment procedures adapted by the therapy could be concluded as follows: The cardioselective toxicity and inhibition of peristaltic activity by the taxine in yew foilage might be involved in the symptoms of acute poisoning as anorexia, dullness, muscle tremor, dyspnea, and sudden death. We also performed the dose response relationship of taxine to the range of clinical symptoms and examined recovery performances. Through the autopsy of the cattle, we could confirm the presence of yew foilages that might have caused the poisoning in the gastrointestinal tract. However, we could not identify further abnormalities in other organs. In this case report, we demonstrated that practice of the forced magnesium sulfate infusion in yew poisoning was helpful for the attenuating the taxine poisoning by blocking the further proceeding of the toxic effect.

        돼지감자분말을 첨가한 도토리묵의 제조 및 품질평가

        이수한,유수인,정남용,신미혜 한국외식산업학회 2019 한국외식산업학회지 Vol.15 No.4

        This study examined the quality characteristics to evaluate the optimal mixing ratio of a Jerusalem artichoke powder (among 0%, 2%, 4%, and 6%) in Acorn Muk. The moisture contents of a Acorn Muk increased significantly (76.13~84.01%) with increasing amount of Jerusalem artichoke powder. The a and b values of the Hunter's color value decreased significantly in proportion to the amount of Jerusalem artichoke powder. In the physical properties, the hardness, chewiness and springiness of Acorn Muk decreased significantly and the cohesiveness of Acorn Muk increased significantly in proportion to the amount of Jerusalem artichoke powder. The total polyphenol contents(22.37~26.35 mg/mL), DPPH free radical scavenging activities(9.58~15.13%) and ABTS free radical scavenging activities(61.23~79.33%) of Acorn Muk increased significantly in groups of Jerusalem artichoke powder. The Acorn Muk containing 4% Jerusalem artichoke powder showed a high score with regard to flavor, moistness, chewiness and overall acceptance. These results suggest that the appropriate amount of Jerusalem artichoke powder for making Acorn Muk is 4%. This study indicate that Acorn Muk treated with Jerusalem artichoke powder had the highest functional component and antioxidant activity.

        수퍼비전 작업동맹척도(WAI-T) 요인구조 탐색

        이수현(李守賢),김동민(金東敏) 서울대학교 교육연구소 2011 아시아교육연구 Vol.12 No.2

        본 연구는 수퍼비전 작업동맹 척도(WAI-T)의 요인구조를 탐색할 목적으로 수행되었다. 이를 위해 수퍼비전을 받고 있는 상담 수련생 245명(남 26명, 여 219명)을 대상으로 수퍼비전 작업동맹 척도를 실시하고 확인적 요인분석과 탐색적 요인분석을 통해 요인구조를 검토하였다. 확인적 요인분석을 실시한 결과 1요인 모형, 2요인 모형, 3요인 모형 모두 적합하지 않은 것으로 나타났다. 다음으로 새로운 요인추출 가능성을 탐색하기 위해 탐색적 요인분석을 실시하였다. 그 결과 2 요인이 추출되었다. 요인 1은 긍정진술문 문항으로 구성되어 있었고, 요인 2는 부정 진술문 문항(역채점 문항)으로 구성되어 있었다. 각 요인에는 원래 목표, 과제, 정서적 유대로 분류되었던 문항들이 골고루 포함된 것으로 나타났다. 이 같은 결과는 수퍼비전 경험이 많은 참여자만을 대상으로 했을 때도 동일하게 나타났다. 또한 부정 진술문 문항으로 구성된 요인 2는 요인 1과 그 의미상 같은 구인을 측정하는 것으로 판단되지만 전체 WAI-T의 구인 타당도와 신뢰도에는 부정적인 영향을 미치고 있는 것으로 나타났다. 이러한 분석 결과를 바탕으로 WAI-T의 활용에 대한 시사점을 논의하였다. The purpose of this study was to examine the factor structure of supervisory Working Alliance Inventory-Trainee(WAI-T). WAI-T was administered to 245 trainees who were currently engaged in clinical supervision. Then, a confirmatory factor analysis was conducted to find the best model among the three models(one factor model, two factor model, three factor model). However, none of these models showed acceptable values on the fitness indices. To examine the possibility of other factor structure, an exploratory factor analysis was conducted. In this analysis, two factors were extracted. Regardless of the original item classifications, the items loaded on Factor 1 were all positively stated. All the negatively stated items were loaded on Factor 2. Factor 1 showed higher correlations with the Counselor Activity Self-efficacy sub-scales than both Factor 2 and full WAI-T. The results of the analysis suggested that at least some of the Factor 2 items were problematic, in that they were interfering with construct validity and internal consistency. Overall, this study suggests that at least Korean trainee may not judges supervisory relationship on the basis of goal, task, and emotional bond as suggested by Bordin(1983).
