      • Spray Dryer를 이용한 배연탈황의 수치모사

        오의경,이형근,김선근,장순희 중앙대학교 생산공학연구소 1995 생산공학연구소 논문집 Vol.4 No.1

        반건식 배연탈황공정에서 사용되는 spray dryer absorber(SDA)에 대한 수치모사를 행하였다. 기본 방정식으로는 기체와 액적의 각 성분들의 물질수지식, 에너지수지식과 액적의 운동 방정식등이 포함되었다. 만들어진 모델은 대부분이 기존의 SPRAYMOD-M보다 실제의 pilot plant date를 더 잘 모사하였다. 실제 pilot plant에서 사용되는 값의 범위 내에서 선정된 공정변수가 SDA의 성능에 미치는 효과를 계산하고, 이를 SO₂의 흡수속도, 배연기체의 체류시간, 그리고 액적의 건조시간 및 속도 등에 의해 검토하였다. 또 SO₂제거율을 두 개의 독립된 공정 변수의 함수로 구하였으며, 그 결과를 3차원 또는 2차원의 등가선으로 표시하여 SDA의 설계에 쉽게 적용될 수 있도록 하였다. A mathematical model has been developed for simulating the spray dryer absorber (SDA) used in semi-dry flue gas desulfurization process. Fundamental equations include the component mass and heat balances in both gas and droplet phases and the equation of motion for a single droplet. The model developed described the pilot-plant data much better than the existing SPRAYMOD-M model. The effect of the process variables, whose values were chosen within the operation limits of the actual pilot plants, on % SO₂removal or conversion of the sorbent were calculated, and discussed in terms of SO₂absorption rate, the residence time of flue gas, the velocity and drying time of droplets. Finally, the % SO₂removal was calculated with two independent process variables and the results were shown on three-dimensional or two-dimensional diagrams with the lines of constant % SO₂removal, so that they can be easily applied to preliminary design of the SDA.

        Purpose: This study was aimed to specify roles of nurses from the anesthesia and recovery room by analyzing nursing activities as well as anesthesia nursing during surgery. Method: The objects were 12 RNs working in the recovery room of a university hospital located in Incheon. Self-report was performed by measuring stop-watch for five days from May 17th to May 21st in 2004. Research method was designed to record the time and frequency of the nursing activity from anesthesia and recovery room based on nurses' statement and other references for five days. The data were analyzed with descriptive statistics, ANOVA, and t-test via SPSS Win 10.0 program. Result: Nursing activities in anesthesia recovery room were classified into two different characteristics such as direct and indirect nursing activity. The activities consisted of 11 direct nursing areas and 39 nursing activities in anesthesia preparation room. The indirect nursing was classified into 8 nursing areas and 32 nursing activities. The direct nursing was classified into 12 nursing areas and 55 nursing activity. Also, the indirect nursing was classified into 7 nursing areas and 21 nursing activities in recovery room. In terms of prevalence of nursing activities in the anesthesia preparation room, observation and cooperation of anesthesia was the most prevalent activity, drug and eqipment management the second prevalent, and drug administration the third. On the other hand, in the recovery room, the most prevalent activity was vital sign checking and observation, the second most prevalent activity informative activity, and the third body temperature control. Nursing activity time was recorded according to the nursing characteristics. In the anesthesia preparation room, the direct nursing spent for 8092.20 minutes was larger than the indirect nursing spent for 7198.50 minutes. Also, in the recovery room, the direct nursing spent for 2361.16 minutes was larger than the indirect nursing spent for 1134.13 minutes. 4. Nursing activity time was compared to duty shifts. In the anesthesia preparation room, the direct nursing was more prevalent on day shift and the indirect nursing was prevalent on evening shift. However, in the recovery room, both direct and indirect nursing activities were prevalent on day shift. Conclusion: The role of anesthesia and recovery room nurses was analysed according to the time, frequency, and its characteristics.

        Zr계 Vitreloy 박막의 특성에 대한 조사

        이경민,이병준,김병훈,이의완,박동수 慶北大學校 師範大學 科學敎育硏究所 1999 科學敎育硏究誌 Vol.23 No.-

        We have grown Zr based vitreloy alloy thin films by thermal deposition methode and ion beam sputtering method and compared them with Zr-Ti-Cu-Ni-Be bulk metallic glass bulk. Thermal analysis caused Zr-Ti-Cu-Ni-Be bulk metallic glass to recrystallize in the two region. The onset point temperature of the first region was 414.12℃ and the peak temperature was 410.02℃. The onset point temperature of the second region was 445.21℃ and the peak point temperature was 454.45℃. The X-ray diffraction measurement and thermal analysis as a function of temperature showed that the bulk metallic glass thin films recrystallize in the same temperature region. As a result, Zr based vitreloy alloy was the same as phase transition of bulk metallic glass bulk and bulk metallic glass thin film.

      • 상속세법상 비상장주식평가규정의 개정이 조세공평성에 미친 효과

        이의경 한국산학경영학회 2004 산학경영연구 Vol.17 No.2

        본 논문은 상속세법상 비상장주식의 평가규정이 개정되면서 조제공평성이 제고되었는가에 대해 검토한 것이다. 조세공평성의 제고효과를 확인하기 위해서 구체적으로는 상속세법상 비상장주식평가 규정을 이용한 평가액이 실제주가에 어느 정도 근접하는가를 체크하였다. 세법상 평가액이 실제주가에 근접할수록 조세공평성이 높아지는 것으로 볼 수 있기 때문이다. 2003년 현재를 기준으로 보면 상속세법상 비상장주식평가규정은 크게 1999년과 2000년 두 차례에 걸쳐 개정되었다. 1999년 이전에는 모든 비상장주식을 순자산가치와 순손익가치의 평균값으로 평가 하였지만 1999년 이후에는 순손익가치가 순자산가치의 50%이상인 기업과 50%미만인 기업으로 구분하여 전자의 경우에는 종전규정을 적용하지만 후자의 경우에 해당하는 기업의 주식은 순자산가치로만 평가하도록 하였다. 그리고 2000년부터는 순자산가치와 순손익가치 중 큰 금액으로 주식을 평가 하도록 다시 변경된 것이다. 본 연구에서는 상장기업을 대상으로 하여 거래소에서 형성된 실제주가를 기준으로 해서 상속세법상 평가액을 개정단계별로 산출해서 실제주가와 비교하여 그 차이에 대한 통계적 유의성을 분석하였다. 그 결과 세법개정은 세법상 평가액이 현실적인 주가를 좀더 정확하게 반영하는 방향으로 이루어졌음을 확인할 수 있었다. 이러한 결과는 상속세법상 비상장주식평가규정이 과세당국의 의도대로 조세불공평을 완화하는 방향으로 이루어졌음을 증명하는 근거가 될 수 있다. This paper examines the effect of the amendment of the valuation method for unlisted stocks in the inheritance tax law. There were many criticisms on the valuation method of the inheritance tax law because the method is not effective in the respect of the fairness in taxation. The method in the inheritance tax law was amended four times since the year 1991. This research focused on whether these amendments increased the impartiality in taxation or not. The finding of the empirical test indicates that as the valuation method were amended, the stock prices calculated by the valuation method were closer to the real stock price. On this ground, I could conclude that the amendments were effective in decreasing the partiality in taxation. In spite of the result, considering the cycle of stock market, I found that the problem of unlisted stock valuation in the inheritance tax law. The law lacks flexibility and elasticity.

        루소에 나타난 성과 정치 : "극장에 대하여 달랑베르에게 보낸 편지"를 중심으로 In the Letter to M. D'Alembert on the Theater

        박의경 淑明女子大學校 亞細亞女性問題硏究所 2004 아시아여성연구 Vol.43 No.2

        “극장에 대하여 달랑베르에게 보낸 편지(이하 <달랑베르>)”에서 루소가 극장을 비난하는 것은 진정성에 대한 루소의 관심으로 보아 지극히 당연한 결과로 판단된다. 극장에 가는 사회문화적 관행과 연극적 표현의 구조는 지속적으로 관리되어야 하는 자기편애(amour propre)를 가진 시민이나 자아를 그 자체로서 가지고 있는 자연적 인간에게 여러 가지 문제를 제기한다. <달랑베르>의 말미에 개진된 공화주의적 연극에 대한 논의에서 연극의 활성화와 연계된 정치적 타락은 성적 타락에 그 뿌리를 두고있다고 루소는 역설한다. 연극에서 만들어진 성적 정체성은 시민적 통일성을 형성하기도 하고 파괴하기도 한다는 것이다. 여기서 개인성은 역할의 수행 자체가 아니라, 역할의 혼동에 부정적 영향을 받게 되고, 조작된 명성과 평판이 바로 그 본질적 성격이다. 성적으로 진솔(authentic)하기 위해서는 행위자 자신이 행동, 자태, 언어 등을 통해서 타인에게 자신을 연출하는 행위양식이 연극에 포함되어야 하고, 이러한 연출을 통한 대표의 의미는 연극의 공연 그 자체에 내재되어 있다는 것이 바로 그에 대한 루소의 대책이었음을 필자는 본 논문에서 논하고자 한다. 강요된 정체성은 언제나 불안정하고, 루소의 정치학은 “무질서한 성성이 지속적인 위협요인”임을 명백히 한다. 게다가 계몽사상가들의 담론이 명백해지면서, 그 정체성이 드러내는 불평등과 부정의는 논쟁거리가 될 수 있다. 루소는 이를 수사학적으로 맞받아친다. 그는 육체를 도입하여 시민의 정치적 상상력을 구속한다. 육체를 도입함으로써 성적 정의에 대한 평가가 성적 욕망이라는 경험적 진실과 분리 불가능하게 된다. 이를 통해서 루소는 입법자의 역설적 딜레마에 명백한 해결책을 제공한다. 필요한 것은 위협이 매력적으로, 역설이 자연스럽도록 보이게 하는 것이다. 따라서 힘이나 이성에 의지하지 않고, 폭력 없이 강제하고 확신 없이 설득하는 작업이 필수적이다. 이는 결과적으로 평화적인 정치적 기초를 설정하는 현명한 입법자의 이미지나 자유의 상징으로서 처벌을 자랑스럽게 생각하는 존경받는 위법자의 이미지에 호소하여 가능한 일이 아니다. 그러나 사랑의 이미지를 통한다면 가능할 것이라고 루소는 주장한다. 이것이 우리가 고통 속에서 즐거움을 발견해 낼 수 있는 일종의 기적이라고 루소는 역설한다. Rousseau’s condemnation of the theater in Letter to M. D’Alembert on the Theater seems to be a logical consequence of his concern for authenticity. Both the sociocultural practice of theatergoing and the structure of theatrical representation pose multiple problems for the citizen whose amour propre must be kept in check and for the natural man who must be kept “entirely for himself.” The discussion of republican entertainments near the end of the Letter to D’Alembert supports the concusion that the political corruption associated with theatergoing is rooted in corrupt sexualities. According to his analysis on the theater, citizen unity is forged or destroyed by sexual identities which must be scripted and choreographed. Here individuality is undermined by the confusion of roles, not by role-playing itself, and an organized publicity the one of its essential moments. As I will argue, Rousseau’s remedies suggest a mode of action in which the self-cum-actor represents itself to others through gestures, poses and worlds and the meaning of the representation is contained within the performance itself. An identity that is enjoined is perpetually unstable and Rousseau’s politics reveal the degree to which disordered sexuality remains a continual threat. Futhermore, as philosophe discourse had made evident, the inequality and injustice that those identities represent can become the subject of disputation. Rousseau enchains the citizens’ political imagination by bringing in the body, thereby making any assessment of gender’s justice inseparable from the experiential truths of engendered desire. In so doing he offers an apparent resolution to the legislator’s paradoxical dilemma. What is required is a way to make the threatening appear inviting and the paradoxical appear natural, and thus, without recourse to force or reasoning compel without violence and persuade without convincing. This is not, finally, possible, by invoking the image of the wise lawgiver who manages a pacific political founding, or the image of the respected lawbreaker who proudly through images of love, whose miracle, Rousseau has discovered, is that it can make us find pleasure in suffering.

        의료기관 외래 이용자의 복약순응 관련 요인분석

        이의경,박정영 한국의료QA학회 2002 한국의료질향상학회지 Vol.9 No.2

        Background: The purpose of this study was to investigate the current status of medication compliance of outpatients and to analyze the factors contributing to mediation non-compliance. Methods: Telephone survey was conducted to the 1,000 outpatients who visited medical institution during the period from January 2002 to April 2002. Subjects were randomly selected from the telephone directories of the nation, and the socio-demographic characteristics of the respondents such as age, gender and region were matched based of those of outpatients in 2001. Results : The results of survey reveals that those who complied with doctors' regimen in the right way accounted for 82.4%. The compliance increased with the strong belief in the medication, less unwanted side effects and inconvenience, more severity of disease, and lower perceived health status. Compliance rate was also higher in the patients group who experienced the drug education by the pharmacists than those who did not. Conclusion: In order to improve drug compliance, drug information on efficacy, adverse reaction, drug interactions, and basic disease information are to be provided to the patients. Drug education needs to be focused not only on providing knowledge of drugs and diseases but also changing attitude on drug use of the patients.
