We demonstrated the synthesis of organic carbonates using alkyl/aryl 4,5-dichloro-6-oxopyridazine-1(6H)- carboxylates and alcohol in the presence of aluminum chloride. Alkyl/aryl 4,5-dichloro-6-oxopyridazine- 1(6H)-carboxylates were reacted with alcohol in the presence of AlCl3 in toluene at room temperature to afford the corresponding unsymmetric and symmetric organic carbonates in good to excellent yields. These are efficient and convenient processes. Alkyl/aryl 4,5-dichloro-6-oxopyridazine-1(6H)-carboxylates are solid, stable and non-toxic CO2/CO2R(Ar) source. It is noteworthy that the reaction is carry out under an ambient and acidic conditions, the easy-to prepare and readily available starting materials and the quantitative isolation of reusable 4,5-dichloropyridazin-3(2H)-one.

칸트의 미학은 정치적인가? 전통적인 주석가들과는 달리, 랑시에르와 리오타르는 이 물음에 긍정적인 답변을 제시하면서 정치에 저마다 고유한 의미를 부여한다. 랑시에르는 『판단력비판』의 ‘미의 분석학’에서 출발하되, 실러의 유희 개념에 담긴 사회적 함의를 참조하면서 자신의 정치 개념을 구축한다. 그에 따르면, 정치란 ‘감각적인 것의 새로운 나눔’이자 그러한 나눔이 야기하는 ‘불화’다. 리오타르는 『판단력비판』의 ‘숭고의 분석학’에서 출발하되 버크의 숭고론을 참조하면서 숭고의 논리를 갱신한다. 예술적 아방가르드는 버크적 숭고의 논리인 ‘이중의 박탈’의 모범적 사례로서, 역사의 최종 목적을 상정하는 정치적 시도들에 비판적 함의를 갖는다. 이 글의 목표는 칸트라는 분기점에서 출발한 두 미학이 가로지른 변형과 이탈의 경로들을 파악하고, 그 새로운 경로들의 방향성과 가치를 가늠하는 데 있다.

The purpose of this paper is to read Ranciere's "Aesthetics as Politics" in relation to Kant's aesthetics. The relations between Ranciere and Kant are found in two aspects. The first is the re-joining of two meanings of aesthetics. Following Kant's terminology, aesthetics has been used in two different senses: as a theory of human sensibility and as a theory of art (more exactly, what he calls the "aesthetic regime of art"). Combining the two in his own way, Ranciere argues that politics has a characteristic of the theory of human sensibility (aesthetics of politics) in the same manner that the theory of art has a political characteristic (politics of aesthetics). Especially for the latter, the politics of aesthetics, he makes reference to Kant's "Analytic of Beauty" in the Critique of Judgment. Ranciere defines it as a politics of aesthetic experience/ education, for which Kant's concept of play is used as a theoretical model. In the Kantian sense, play means a sort of aesthetic attitude. It takes on a double role: The first is the transition from regulative judgment to reflective judgment. Through this transition, reason loses its control over sensibility. The second is the indifference of aesthetic judgment. Benefiting from this indifference, aesthetic judgment can assert its universality, despite being a singular judgment. Existing theories of modernism have explained the political function of art based on the autonomy of the artwork and the personality of the artist. Contrary to such theories, Ranciere insists that the main point of his aesthetics is in the aesthetic experience/education (more exactly, the possibility of expanding a certain aesthetic attitude, i.e., play), not in the artwork or the artist. However, the thing with Kant is, he only rediscovers the order of nature in play. In contrast to him, Ranciere expresses sympathy with Schiller's view, insisting on the advent of renewed humanity through aesthetic experience/education. If a new distribution of the sensible (Le partage du sensible) can be established, it would be possible in the aesthetic experience/ education acquired and expanded in play.

With the current consumer trend toward health and wellbeing, the demand for consumption of fresh cut vegetables has been increasing. As a popular vegetable with functional components, sedum (Sedum sarmentosum) is widely used in Korea as a side dish that needs no cooking. In this study, to provide a hurdle technology for postharvest sedum, the effects of combined treatment of 1% acetic acid for washing and 10 kJ/m2 UV-C irradiation on the microbial growth and quality of sedum were examined. After the treatment, the sedum samples were stored at 10℃ for six days, and the results of their microbial analysis as well as their color, vitamin C content, and antioxidant activity were analyzed. The combined treatment with acetic acid and UV-C irradiation reduced the initial populations of the total aerobic bacteria and the yeast and molds in the sedum by 3.28 and 4.22 log CFU/g, respectively, compared to those in the control. The Hunter L, a, and b values of the sedum did not significantly differ across the treatments. In addition, the vitamin C content and the antioxidant activity decreased significantly during the storage, regardless of the treatment. These results suggest that the combined treatment with 1% acetic acid and 10 kJ/m2 UV-C irradiation can be useful as a hurdle technology for retaining the microbiological safety and quality of sedum during its storage.
