The rate constants for the hydrolysis of the derivatives of α-bromobenzaldehyde-p-nitro-phenylhydrazone (p-H, p-OCH_3, p-Cl, p-NO_2) at various pH have been determined by UV spectrophotometry in 50% dioxane at 25℃ and the following rate equations which can be applied over wide pH range were obtained. i. e. α-bromobenzaldehyde-p-nitrophenylhydrazone; kobs.=1.25×10 exp (-7) + 7.92×10 exp (-11)/〔H^+〕+1.51×10 exp (-7) α-bromo-p-chlorobenzaldehyde-p-nitrophenylhydrazone; kobs.=1.06×10 exp (-7) + 1.08×10 exp (-10)/〔H^+〕+1.45×10 exp (-7) α-bromo-p-methoxybenzaldehyde-p-nitrophenylhydrazone; kobs.=1.79×10 exp (-7) + 1.40×10 exp (-10)/〔H^+〕+4.08×10 exp (-7) α-bromo-p-nitrobenzaldehyde-p-nitrophenylhydrazone; kobs.=7.10×10 exp (-8) + 2.89×10 exp (-10)/〔H^+〕+2.37×10 exp (-7) Below pH 2, the rate of hydrolysis of α-bromobenzaldehyde-p-nitrophenylhydrazone is accelerated by electron-donating group (ρ=-0.91). Above pH 5, however, this reaction is slowded down by electron-attracting group (ρ=0.37). From the rate equation and the effect of solvent and substituent upon the rate of reaction, below pH 2, the hydrolysis proceed through SN_1 mechanism. Above pH 5, the hydrolysis proceed through 1.3-dipolar ion mechanism. And in the range of pH 2∼5 these two reactions occur competitively.

The structure-antifungal activity correlations between the structure of fourteen new 1-(phenoxymethyl)benzotriazoles (I) (Y=0), 1-(thiophenoxyrnethyl)benzotriazoles (II) (Y=S) and 1-(azidomethyl)benzotriazole (Ⅲ) derivatives were synthesized, and their activity, fifty percent inhibition of mycelial growth(pI_(50)), in vitro against Pyricularia oryzae, Fusarium axysporum f. sp swami, Valsa ceratosperma and Botrytis cinerea were investigated using a generalized QSAR method. The activity of (I) was superior to those of (II) and (Ⅲ). The effect of the substituents (X) on the phenoxy group (I) was rationalized by a parabolic function of electronic (σ), steric (B₁) and hydrophobic parameter(π), and hydrogen bonding (HB). Where the optimal values of substituent on the fungicidal activity againt P. oryzae and F. axcysporum f. sp. sesami are B₁=1.40A; (H) and σ=0.07∼0.15;(H), and those of substituent on the fungicidal activity against V. ceratosperma and B. dare σ=0.23∼0.28; (Cl), π=0.70; (Cl), respectively. The most effective compound ( I a) and ( I d) were examined in this study.

權奇星,朴文奎,成洛道 충남대학교 자연과학연구소 1974 學術硏究誌 Vol.1 No.1

The rate constants for the addition reaction of iso-propylmercaptan to ethylcrotonate have been measured by iodometry and for the proposed reaction mechanism a rate equation which can be applied over wide pH range was derived. From this rate equation, it was found that below pH 6.0 the reaction is started by addition of iso-propylmercaptan molecule and above pH 11.0 this reaction is proceeded by the iso-propylmercaptide ions and a t the range of pH 6.0-11.0 two reactions are competitive. Consequently, it is found that the observed data are satisfactorily accorded with the theoretical values over various pH range.

Ethylcinnamate에 對한 Iso-propylmercaptan의 親核性 添加反應에 關한 反應速度論的 硏究

權奇星,李天培,成洛道 圓光大學校 1977 論文集 Vol.11 No.-

ethylcinnamate에 대한 iso-propylmercaptan의 친핵성 첨가반응 속도상수를 측정하여 넓은 pH 범위에서 잘맞는 반응속도식을 얻었다. 이 식에 의하면 pH 6.5 이하에서는 iso-propylmercaptan과 iso-propylmercaptide ion의 첨가가 경쟁적으로 일어난다. pH 10이상에서는 ethylcinnamate에 iso-propylmercaptide ion의 첨가만이 일어남을 알수 있다. 그러므로 본 실험에서 구한 반응속도식으로부터 실험측정값과 계산 값(이론 값)이 여러 pH를 통하여 잘 맞기 때문에 넓은 pH범위내에서 일어나는 친핵성 첨가반은 mechanism을 잘 설명할 수 있었다. The rate constants of nucleophilic addition reaction of iso-propylmercaptan to ethylcinnamate were determined at various pH and a rate equation which can be applied overwide pH range was obtained; ?? The rate equation reveals that below pH 6.5 the reaction is initiated by addition of iso-propylmercaptan molecule, from pH 6.5 to 10.0 iso-propylmercaptan and iso-propylmercaptide ion are competitively added. Above pH 10.0 the addition reaction of iso-propylmercaptide ion occurs. From these rate equation, we found that observed data accorded satisifactorily with theoretical value over various pH range. Hence, the mechanism of nucleophilic addition reaction over wide pH range can be fully explained.

인간심리와 지도력의 상관관계에 관한 연구

권기성 光云大學校 1985 論文集 Vol.14 No.-

The purpose of this study is to build and examine the hypotheses about the relationship between cognitive psychology and leadership in Korean government organizations. In order to study the relationship, this theses attempts to research the followings; 1) Cognitive psychology……concept, affecting factors, and styles. 2) Leadership……concept and styles. 3) Correlation between cognitive styles and leadership styles. 4) The human behavioral management model in government organizations that comes from the integration of cognitive styles and leadership styles. For this study, hypotheses shall be formed through critical relate littratures. The questionaire method has been used to theme hypotheses. The data collected for this thesis was analysed by using mean, standard deviation, coefficient of correlation and F-ratio. The findings of the examination of hypothesis mentioned above are the followings: Frist, in the Korean government organizations, the negative cognitive attitudes (M= 2.57, S=1.14) and the punishment cognitive attitudes(M=2.55, s=1.15) are dominant. Second, it is shown that in the Korean government organization authoritorian leadership is dominant (M=2.70, s=1.17). Third, the examinition of the correlation between the cognitive styles and leadership styles in Korean government organizations reveals the followings: (1) The correlation between authoritarian leadership and positive cogntion is a negative relationship (r=-0.78). (2) The correlation between authoritarian leadership and negative cognition is a positive relationship (r=0.63). (3) The correlation between democratic leadership and positive cognition is a positive relationship (r=0.58). (4) The correlation between democratic leadership and negative cognion is a negative relationship(r= -0.52). (5) The corretation between authoritarian leadership and reward cognition is a neagtive relationship (r=-0.79). (6) The correlation between authoritarion leadership and punishment cognition Is a positive relationship (r=0.69). (7) The correlation between democratic leadership and reward cognition is a positive relationship (r=0.77). (8) The correlation between democratic leadership and punishment cognition is a negative relationship (r=-0.57). Fourth, the examination of the human behavioral management model in the Korean government organizations(which comes from the integration of the leadership styles and the cognition styles) indicates the followings; (1) Positive-authoritarian style is of high productivity (M=4.56, s=0.532), and negative-authoritarian style is of low productivity(M=2.76, s=0.387) (F=36.71, d. f. =1/457, p<0.01). (2) Positive-democratic style is of high productivity(M=4.75, s=0.432) and negative-democratic style is of low productivity(M=2.65, s=0.496) (F=35.78, d.f.=1/457, p<0.01). (3) Reward-authoritaran style is of high productivity(M=4.12, s=0.62) and punishment-authoritaran style is of low productively(M=2.73, s=0.49) (F=42.15, d.f.=1/457, p<0.01). (4) Reward-democratic style is of high productivity(M=4.56, s=0.45) and punishment-democrutic style is of low productivity(M=2.81, s=0.50) (F=40.08, d.f.=1/457. p<0.01).
