The computerization is an important factor for scientific construction management. Con-struction management softwares are being widely used for computerizing project control and scheduling. The code systems in those softwares enable various classifications of con-struction information such as filtering, sorting and grouping, and facilitate easy appli-cation of computer system. This study analyzes the code systems of three softwares, which are representatively used in the construction sites, through a comparative analysis for the applicability in construction management. Finally the study suggests a desirable structure of code system and a selection criterion of software to improve the applicability of construction management softwares in the construction sites.

비양성자성 용매에서 2-tert-Butylcyclohexanone tosylhydrazone의 열분해 반응

郭永佑 慶北大學校 1989 論文集 Vol.47 No.-

In aprotic media tosylhydrazone compound thermally decomposes with loss of nitrogen giving carbene. Decomposition of 2-tert-butylcyclohexanone tosylhydrazone in the presence of N-methylpyrrolidone and sodium methoxide led to a mixture of hydrocarbon products, which are descerned via gas chromatograph on a methyl phenyl silicone column. The observed products, 1-tert-butylcyclohexene and 3-tert-butylcyclohexene, were identified by spectroscopic mithods. The product ratio indicated the approximate order of migration for hydrogen.

김승수,곽병곤,김영대,김우경,김영균,이종국 白中央醫療院 2005 仁濟醫學 Vol.26 No.1

Objectives: The aim of this study was to describe the clinical characteristics of enuretic children and to evaluate the efficacy of treatments. Methods: Our study subjects enrolled were 52 children with nocturnal enuresis, who visited outpatient clinic of pediatrics in Seoul Paik Hospital and Ilsan Paik Hospital, during the period from October 1998 to August 2004. The data of gender, age, family history, symptom, clinical type of enuresis and drug therapy were collected and analyzed retrospectively. Results: The male : female ratio was 2.25 : 1. The mean age at diagnosis was 6.8 years with an age range from 4.3 years to 12.5 years. Fourty five cases(86.5%) were diagnosed as primary enuresis and 7 cases(13.5%) were diagnosed as secondary enuresis. A family history of enuresis was noted in 5 cases(9.6%) including 4 cases with parental enuresis history. The accompanying urinary symptoms were urgency(11.5%), frequency (7.7%), and dysuria(2.0%). Conclusion: We found frequent occurrences of enuresis in boys and primary type and an occasional association with a family history of enuresis. The two main treatment modalities were behavior control with an alarm system and drug therapy with imipramine, desmopressin, or oxybutynin. We recommend continuous drug medications to control nocturnal enuresis along with encouragement.

송화영,곽이경,김민,조종래,엄태현,장우익 대한감염학회 2009 감염과 화학요법 Vol.41 No.5

Although Staphylococcus epidermidis is a frequent cause of prosthetic valve endocarditis (PVE), it is regarded as a rare pathogen of native valve endocarditis (NVE). We report a case of NVE caused by methicillin-resistant S. epidermidis in a 62-year-old man. The bacterium was isolated from blood and tissue culture. The patient underwent valve replacement due to heart failure and was successfully treated by surgery and vancomycin administration for 7 weeks.

아세톤 溶媒속에서 N,N^´-디메칠아닐린의 벤조일레이숀 親核置換反應에 관한 연구

呂壽東,郭永佑 慶北大學校 1975 論文集 Vol.20 No.-

The rate of the reaction of N, N'-dimethylaniline with various substituted benzoylchlorides has been measured by using spectrophotometer in acetone at 580㎚ and three different temperatures. The reaction was second order overall and pseudo first order with respect to each reactant. The rate constants were increased by electron-donating substituents, while they were decreased by electron-withdrawing groups. However, reaction of p-bromo and p-chloro benzoylchloride with N, N'-dimethylaniline had an abnormality in comparison with m-nitro and p-nitro benzoylchloride. Kinetic investigation carried out on this reaction showed that C-Cl bond breaking reaction predominates in the case of electron-releasing substituent but C-C bond making reaction becomes increasingly in the case of electron-withdrawing substituent. Activation parameters for the benzoylation were calculated.

물-메타놀 混合 溶媒에서 Pb-Acetate의 熱力學的 性質에 關한 硏究

朴裕哲,吳相午,郭永右 慶北大學校 1973 論文集 Vol.17 No.-

Activity coefficients and solubility products of Pb-Acetate(10^(-1)∼10^(-4) mole/l) from aqueous solution to the solution of water-methanol mixtures are investigated by electromotive force measurements at 25℃. The effect of dielectric constant of various solvents on these physical constants have been considered on quantitative basis. We are suggested that the relationship between the meen activity coefficients(r^*_±) and solubility products(k^*_s) in a reference solvent and those in other solvents is represented as follows; logr^s_±=logr^*_±+n, where n is -logr^*_s/k^s_s. Futher, we estimated the difference of the free energy change of transfer of Pb-Acetate from aqueous solution to the solution of water-methanol mixtures and the ion-size parameter of Pb-Acetate. The values of the ion-size parameter varies from 3.8Å to 4.4Å. Considering the free energy change, it is possicle to assume that the salt in the solvent of higher dielectric constant may be dissolved by electrostatic force rather than non-electrostatic force.

敎育政策의 實際的 變遷에 관한 實證的 硏究 : 敎育豫算 彈性値 分析을 중심으로

This study aims to expose what is going on in educational policy change at a financial level for thirty years (1960-1990). Based upon this research questions' findings, we enabled to compare the planning with the implementation of educational development programs. To analyze these research questions, this study uses data including educational budget and policy reports made by the ministry of education during 1960-1990. The educational budget data were analyzed with regression models using loglinear transformation. This study finds scale of educational budget to total government budget is a little elastic(elastic coefficient= 1.05). However, in the near future we cannot expect the amount of educational budget to increase as much as we need to make students' educational circumstances at an optimum level. This is because of "small government policy" in the sense of financial scale, which has helped Korean firms to accumulate capital through exemption from many kinds of taxation. We think the policy priority of economic and social development goals(esp. excellence of education) should be readjusted as soon as possible. The most important policy to our ministry of education during the last thirty years seems to increase the equal opportunity of education in terms of access. It is prior to other educational policy goals such as an equal opportunity of educational process, excellence of education etc.. What is surprising is that budget of special education for handicapped to total educational budget is quite unelastic(elastic coefficient =.870). Special education has to be supported more strongly if the ministry of education considers equality of education the most important policy goal. Regarding policy of excellence education, textbook compilation, budget and audio-visual education budget to total budget of the ministry of education are unelastic. Good textbooks and teaching methods are critical for a high quality of education. The ministry of education should concern these areas financially as well as nominally in order to improve the quality of education in an efficient way. Both the budget of vocational education(1.06) and that of social education(1.32) to total budget are elastic. The former seems to be considered very important in an economic sense and the latter in the sense of equality of educational opportunity for non-school population. However, the budgetary amount of vocational education should be increased much more in the near future. If not, the present proportion of highschool students of nonvocational school to vocational school(64 : 36) will not be able to be reverted to nominally aimed proportion(3 : 7). The lack of supply of workers in the Korean labor market today will not be loosened, either. What is more important among this study's findings is a gap between nominal policy goals and actual goals. That is in most educational policy fields we did not find statistically significant differences in terms of educational budget scale between years announced officially to be important and years not announced. These findings prove dual structure between educational planning and implementation. We argue planning and financial allocation to be consistent in order to get rid of educational planning divorced from implementation contexts, or implementation unhitched from some form of planning. Without strong links between the planning and implementation of educational development programs, we cannot achieve programs of educational development efficiently.
