옥종호,이창우 서울産業大學校 2005 논문집 Vol.54 No.2

The Ministry of Education and Human Resource Development has implemented the Construction Cost Saving Policy since 1998. The National Universities and Regional Education Committee have been required to follow the details of the Policy in constructing educational facilities in their jurisdiction. While the Policy has positive effect on construction cost saving of the entities, it has been criticized from the beginning of the Policy implementation because of its negative impact on project quality, education quality, trust in the public sector construction business, and solvent operation of the private construction companies which build the educational facilities in the entities. The research aims at investigating the pitfalls of the Policy and suggesting more reasonable approaches that can satisfy both the governmental entities and the private companies.

리스크 영향을 반영한 공기산정 방식에 관한 연구 : Fuzzy Set 이론 적용기법

옥종호,오병석 서울産業大學校 2005 논문집 Vol.54 No.2

Risk and uncertainty are inherent in all construction projects. Appropriately determining a project schedule under risk and uncertainty is one of the most important factors in a contractor's succeess on a project. However, when the likelihood of inccurring risk events and the risk-associated consequences (schedule overrun or schedule reduction) is uncertain, contractors face difficulties in estimating a project duration. While the Critical Path Method (CPM) has been widely used in scheduling a project, it is frequently criticized because (1) CPM assumes that an activity's duration can be estimated with certainty and (2) in consequence, CPM cannot reflect the project risk and uncertainty in schedule estimation. The main objective of this paper is to present a schedule risk quantification method for estimating a risk-associated activity's duration. The uncertainty in the quantified risk consequences (activity duration loss or gain) is accounted for by using a fuzzy set approach. A numerical example is presented to show how the method can be put into practice and how suitable it is in measuring risk-associated activity duration.

옥정원,이종호,권희준 한국방송광고공사 2009 광고연구 Vol.0 No.83

본 연구의 주요 목적은 크게 세가지 차원에서 언급될 수 있는데, 먼저 모바일 쿠폰의 미소지로 인한 후회감과 이러한 후회감에 영향을 주는 모바일 쿠폰의 특성이 무엇인지를 살펴보는데 있다. 둘째, 그러한 후회감의 해소과정이 어떻게 형성되는지 살펴보는 데 있으며, 마지막으로 이러한 후회감형성과 후회감 해소과정이 해당 소비자들의 구매후 행동에 어떠한 영향을 미치는지를 알아보는데 있다. 본 연구의 결과, 모바일 쿠폰의 특성은 해당 쿠폰의 미소지로 인한 후회감과 어느정도의 영향관계가 있는 것으로 밝혀졌으며, 이러한 후회감은 이를 해소하기 위한 과정으로 이어짐이 나타났다. 특히, 정보탐색과 후회감 해소에 대한 기대의 경우 해당 고객의 만족과 재구매 또는 방문과 관련이 있는 것으로 나타났다. 다만, 선행연구와 달리 인지부조화에 바탕으로 둔 자기설득의 경우에는 모바일 쿠폰의 후회감 해소과정에 있어 상대적으로 중요하게 작용하지 않은 것으로 나타났다. 이러한 연구결과는 모바일 쿠폰의 표적 선정에 있어 후회감 지각 및 이의 해소과정과 관련한 사용성향이 중요하게 고려될 수 있음을 반증하는 것으로 모바일 쿠폰을 통한 프로모션 전략을 수립시 차별화의 요소로 작요할 수 있다. The goal of this study is to examine that how the regret that consumers feel when they don't use mobile coupon affects consumers' behaviors after purchasing in connection with the common use of mobile coupon. Also, this study examines that the regret about unusing coupon, negative emotion regards as a mediator between satisfaction/dissatisfaction and post-purchase behaviors. Especially this study analyze three path model, to explain the effect of consumer regret on repeat and switching behavior. The results from the our research are following: First, propensity to use and recognized benefit of mobile coupon affect significantly regret by not using it. Second, regret by not using mobile coupon makes customers have regret solution. Third, regret solution by not using mobile coupon, information research effort and recovery expectancy increase customers satisfaction and intention of repurchase. Forth, in regret solution, self persuasion doesn't increase customer's satisfaction and intention of purchasing. Therefore, it is expected that efficiency and effectiveness of promotion program are improved by understanding consumers' needs as it is and by issuing mobile coupon that is suitable to targets. Also, it is driven marketing methods in promotions through mobile coupon system that is differentiated suitably will help to increase satisfaction, intention of using and re-visit.

옥종호,경갑표 서울産業大學校 2005 논문집 Vol.54 No.2

건설분쟁은 주로 계약당사자간의 계약조건을 둘러싼 갈등으로부터 야기된다. 그러나 직접적인 계약관계가 없는 발주자 또는 계약자 하부조직 간의 갈등 역시 빈번하게 계약당사자 간의 분쟁요인을 제공하게 된다. 그러한 조직 간의 갈등요인을 파악하고 효과적인 해결방안을 마련하는 것은 건설관리자가 수행하여야 할 중요한 업무중의 하나이다. 성공적으로 하부조직 간의 갈등을 해결하기 위하여 건설관리자는 여러 가지 갈등해결 방법의 장단점, 각 방법 운용에 따른 갈등해결의 결과, 해결 과정에 내재되어 있는 심리적인 전이 등을 이해함이 필요하다. 본 연구의 목적은 발주자 하부조직 간의 갈등사례연구를 통하여 위와 같은 사항에 대한 건설관리자의 이해를 높이기 위한 것이다. 우리나라 한 지방정부의 시민회관을 건립하는 과정에서 공사에 관련된 두 단위 조직간에 발생하였던 갈등 관계를 분석하며 그 갈등 해결 과정에 포함되어 있는 접근 방법과 갈등당사자간의 심리적인 변화 등을 분석한다. 사례 분석 결과를 바탕으로 건설사업 추진 시 효과적인 갈등해결을 위한 향후 연구방향을 제안한다.

118 patients with hemoptysis were reviewed retrospectively to identify etiologic factors, clinical features, and treatment and to evaluate the usefulness of fiberoptic bronchoscopy. 63 cases (53.4%) were blood-tinged sputum, 2 cases (1.7%) were more than 600ml a day in amount of hemoptysis. Pulmonary tuberculosis was 37 cases (31.36%), the most common cause of the known etiologic factors. Lung cancer was 6 cases (5.09%). 6 patients (5.09%) were treated with bronchial artery embolization, 1 patient (0.85%) treated with right lower lobectomy. 1 (4.3%) of 23 patients with hemoptysis and normal chest roentgenogram was found to have lung cancer. We suggest that in patients with hemoptysis and normal chest roentgenogram, routine fiberoptic bronchoscopy is not necessary to exclude malignancy.

김주옥,김선영,김관형,서지원,박석영,이종진,박성학 대한감염학회 1995 감염 Vol.27 No.4

목적:폐렴, 기관지염, 만성기관지염에서 fluoroquinolone제제로서 항균력이 강하고, 혈중 반감기가 길고, 객담과 조직내 농도가 높은 sparfloxacin의 안전성과 효과를 enoxacin과 비교하기 위해 본 연구를 시행 하였다. 방법:1994년 10월부터 1995년 4월까지 충남대 부속병원과 대전 성모병원에 내원한 폐렴, 급성기관지염, 만성기관지염이 급성으로 악화된 환자 63명을 대조군(32명)(enoxacin 100 mg 1일 3회 경구투여), 실험군(31명)(sparfloxacin 200mg 1일 1회 경구투여)으로 나누어 임상증상, 세균학적 객담 검사, 혈액검사, 실험실내 항균력검사로 그 치료율 및 안전성을 비교하였다. 결과: 1) 임상종합 평가, 세균학적 균소실, 안전성, 유용성에서 두군간에 의미 있는 차이는 없었다. 2) 시험관내 항균력검사상 MIC가 실험군이 대조군보다 현저하게 낮았다.(p<0.05). 3) 경미한 두통, 식욕감퇴, 상복부 불쾌감, 설사등이 대조군 9예, 실험군 7예에서 발생하였고, 검사실 소견상 SGOT 혹은 SGPT 의 일시적 경미한 상승이 대조군 2명, 실험군 3명에서, 혈중 creatinine 상승이 실험군 2명에서 있었으나 경미하였다. 결론:이상의 결과로 sparfloxacin은 폐렴, 급성기관지염, 만성기관지염의 악화에서 하루 한번 투여로 enoxacin 하루 3번 투여와 유사하게 효과적이고 안전하며, 시험관내 항균력이 enoxacin보다 월등히 우수하여 임상에서도 유용하게 사용될수 있을것으로 생각된다. Background: Sparfloxacin, a new oral quinolone, has a broad spectrum, potent antimicrobial activity, prolonged half life, high concentration in sputum. The clinical efficacy and safety of sparfloxacin have been reported by some previous clinical studies performed in Japan. The objectives of this study were to evaluate the clinical and antimicrobial efficacy of this drug in respiratory tract infections compared to those of enoxacin. Methods:We performed an open controlled, randomized study in 63 patients with acute bronchitis, pneumonia, and exacerbation of chronic bronchitis at Chung Nam University hospital and Dae Jeon St. Mary's hospital from October, 1994 to April, 1995. In the control group(n=32), 100 mg enoxacin was administered orally 3 times a day and in the test group(n=31), 200 mg sparfloxacin once a day. Results: The results were as follows; 1) There were no significant differences between the two groups in clinical efficacy, bacteriological finding, and usefulness. 2) Means and SD of MICs were 0.44±0.89 ㎍/ml in the control group, 0.13±0.24 ㎍/ml in the test group. There was a significant difference in MICs between the two groups(p<0.05). 3) Headache, epigastric discomfort, and loss of appetite were observed in 7 cases of the control group and in 9 cases of the test group, and transient elevations of hepatic enzyme in 2 cases of the control group, and in 3 cases of the test group. There was mild elevation of serum creatinine in 2 cases of the test group. Those laboratory abnormalities by therapy might be associated with their underlying diseases. There were no significant adverse effects caused by the drugs Conclusion:In conclusion, sparfloxacin of 200 mg once a day was as effective and well tolerated as enoxacin of 100 mg three times per day in the treatment of respiratory tract infections. Sparfloxacin is more potent antibiotics because MICs of sparfloxacin were very lower than those of enoxacin.

Polymerase chain reaction (PCR) is the most sensitive and rapid method for the diagnosis of M.tuberculosis infection. Many reports have shown different methods for mycobacterial DNA extraction, but revealed many differences in simplicity and time-consumption. We studied which method was the best among 7 different ones for DNA extraction from 32 smear-positive sputa, using PCR of targeting 123bp DNA fragment of IS6110. The methods were the following : SDS-Microwave oven method, NaOH Lysis method, Triton X-100, Proteinase K method, Lysis buffer method. SDS-Proteinase K method, Bead Beater method, and Bead Beater/CTAB method. The amplification products were identified by electrophoresis on ethidium bromide-stained agarose gels, and confirmed by restriction enzyme, Southern blot hybridization, and DNA sequencing. All 32 cases were positive (100%) by the 7 different methods. It took 1 hour or more to detect DNA in SDS-Microwave oven method, NaOH Lysis method, and Bead beater/CTAB method. It took 2 hours or less in the others. SDS-Proteinase K method and Bead Beater/CTAB method were simpler and more convinient than the others. These results suggest that SDS-Proteinase K method and Bead Beater/CTAB method might be better than the others for the extraction of mycobacterial DNA in terms of simplicity and time-consumption, although all the methods were sensitive.

The present study aims at the analysis of the rise of business houses and economic concentration in India. The causes of concentration of economic power in the hands of a few business groups in Indian industries are various. Primarily these are to be found in the nature and distribution of entrepreneurship among the India people. Also important are the historical and other forces which did not allow the growth of a proper climate of enterprise in India. The concept of 'Business House' in India, for a long time, continued to be equated with a 'Managing Agency House'. Factors behind the rise of business house can be divided in this study into three broad categories. In the first category are placed the factors that have had their origin in the problems of entrepreneurial growth in India, its nature and regional distribution. From the very beginning up to this date entrepreneurial activities in the fields of industry and trade have been concentrated in certain religious and regional groups like the Marwaris, Parsis and the Gujaraties. This regional and commercial concentration of economic power is an extremely important sociological phenomenon which cannot be ignored in India condition. In the second category are placed the factors that have their roots in the shortage of venture capital and finance in the country in the colonial context. The nature of industrial finance in India, the difficulties faced by the new entrepreneurs in securing the necessary finance for their project are to be considered here. In the third category includes the factors which owe their origin to the economic policies of the state. The role of the state after independence in promoting private business and concentration of economic power is also important factor. It is hoped that the present work may contribute to a proper understanding of the complex problem of business houses and concentration of economic power in India.

김(海苔) 貯藏中의 褐變反應

With respect to sugar, amino acid, pigment and other components in dried laver, every individual component has been known so get lost during the storage. In this study, th spectral property of the brownish pigment appeared in the water dialyzed fraction from laver extracts, which might be produced by such reactions as degradation and interactions among the components was investigated. Futhermore, the related reaction for the formation of browning pigment like nonenzymatic browning and tendency of the reaction under different storage conditions were also discussed. In the analysis of absorption spectra of the brownish pigment, and absorption maximum at 320 nm and two absorption zones in between 440 to 460nm, and 500 to 560 nm, while the peak at 320 nm reduced with the progress of browning but two others showed gradual increase. the absorption at 440 to 560 nm corresponded to the wavelengths generally applied to the determination of browning. From the results of the model system where xylose or glucose added alone or both (1:1 mole ratio) to the extracts of laver, the addition of sugar and amino acid, the increase of heating temperature, and the prolongation of reaction time activated markedly the reaction rate as generally encountered in the Maillard type browning reaction and so the system was progressively affected by pH increase of 3 to 6 and showed a reduced rate of reaction by th addition of inhibitor that the browning of laver is elucidated as the sugar-amino reaction. The 20 to 30 percent loss in both amino acid and reducing sugar content during 2 month storage was closely correlated with the increase of absorbance at 440 nm, which supports that the consumption of sugar and amino acid was attributed to the formation of brown pigment. In the observation of spectral changes when stored under four different conditions where at water activity of 0.065 and 0.76, 30℃ and room temperature respectively, the reaction rate was decisively affected by the water activity rather than the storage temperature. In consideration of above results, it is concluded that the brown pigment in laver extracts is formed by sugar-amino reactions and that the ambient humidity during the storage is assured to influence the rate of browning reaction.
