Series of (E)-1-aryl-3-(2-pyrrolyl)-2-propenones, that were aldol condensation products between pyrrole-2- carbaldehyde and m- and p-substituted acetophenones, were prepared and their 1H and 13C NMR spectra were examined to obtain the information on the conformation of the enone system. Similar studies were carried out with (E)-3-aryl-1-(2-pyrrolyl)-2-propenones that were prepared from 2-acetylpyrrole and m- and p-substituted benzaldehydes. The substituent chemical shifts were studied by applying the Hammett relationship.
Substituent Chemical Shifts of (E)-1-Aryl-3-thienylpropen-1-ones

Substituent chemical shifts were examined for the 2- and 3-thiophene derivatives of chalcone and compared to the thiophene series of derivatives with the phenyl series. The chemical shift values for the α-carbons of the enones showed and inverse correlation with the Hammett σ values, but the correlation coefficients were moderate (r = 0.836 - 0.878). On the other hand, the β-carbons showed a normal correlation with excellent correlation coefficients (r = 0.994). The absolute magnitude of the ρ values for the α-carbon are about half of those of the β-carbon. The observation may be the result of a through-space transition of the electronic effect of the substituents in addition to the through bond transition
協力에 의한 地方政府 改革의 例 : 大都市圈域共同體를 中心으로(프랑스) le Cas des Communautes Urbaines en France
韓仁淑 東亞大學校 大學院 1980 大學院論文集 Vol.4 No.1
L'exemple des communautes urbaines parait significatif de la facon dont s'etablissent les rapports de 1'Etat et des collectivites territoriales. Au depart, le legislateur souhaite diminuer le cout financier des services et des eguipements dans les grandes villes et, partant, croit que 1'Etat aura moins souvent a intervenir pour equilibrer les budgets des communes. Mais, 1e jeu des differents acteurs dejoue ces previsivons. Les communes rejettent sur la communaute urbaine le maximum de charges. Celle-ci doit recourir a 1'Etat. Or, ces charges sont devenues, sous la pression conjuguee de toutes les parties prenantes, beaucoup plus importantes qu'elles ne l'etaient initialement. L'Etat doit donc non seuilement intervenir, mais encore il doit apporter une aide accrue. Certes, la population n'est sans doute pas mecontente de voir ameliorer son cadre de vie par la multiplication des travaux d'equipements et de 1'autonomie des collectivites locales, on est amene a penser que la loi du 31 decembre 1966 a echoue.

Secondary schools in Korea have been faced with several critical problems with regard to science education. Among them one of the most fundamental problems is associated with laboratory-based science education. There fore as a part of research project for the improvement of science education in secondary schools, this study had its abjectives to inquire into the following areas related to laboratory experiment. ○ Survey and analysis of theoretical backgrounds for science teaching focused on laboratory experiments. ○ Status survey of experiment-based science teaching in high schools. ○ Development of model for improving experiment-based science teaching. In order to fulfill these objectives this study used methods of eiterature review, survey, and interviews. The major finding are as follows: ○ Some topic for laboratory experiments as oppeared in the textbooks are not appropriate in the light of sience curricular operations in high schools. ○ In some schools equipments and facilities of school laboratories are for from sufficiency. ○ Laboratory experiments are not financially supportel for ideal science teach in both mide schools and high schools. These are not on exhaustive list of findings from this study More finding and teaching model for improvement of science education are also described in this paper.

Anticoagulation therapy must be done to patients with mechanical heart valves for prevention of thromboembolism (TE). But, there are no guidelines for the optimal therapeutic range of anticoagulation therapy in Korean patients. Thus, this study performed to evaluate the optimal therapeutic range in International normalized ratio (INR) value in Korean patients with mechanical heart valves. The charts and ACS records of 252 patients with mechanical heart valves who have been followed up at the department of thoracic cardiovascular surgery of Korea university Anam hospital were reviewed retrospectively from Feb. 2002 to Sep. 2005. The target INR range was between 1.5 and 2.0. Mean duration of follow up was 2.9 years and total duration was 746.67 patient-years. All patients were treated with antiplatelet agents. Complications occurred in 18 patients (10 cases of TE, 8 cases of major bleeding), but only 12 cases(7 of TE, 5 of major bleeding) contributed to analysis of the complication incidence. The incidence of complications per 100 patient-years in each INR 1.0~1.49, 1.50~1.99, 2.0~2.49, 2.5~2.99, ≥3.0 was 2.41, 0.35, 0.80, 2.52, 11.43, respectively. In conclusion, the INR range of the lowest incidence rate of complication was between 1.5 and 2.49 in Korean patients with mechanical vale replacement (p=0.01).
