The objective of this study is to develop an search technique for control valve to cut off in case of accident of pipeline. A graph algorithm is used for searching technique for control valve. The graph algorithm consisted of generating pipeline data and searching valve parts. The pipe networks data is constructed in form of adjacent lists and considered as undirected graphs. Breadth-First Search (BPS) is used for graph traversal to find the control valve. This selection algorithm of the control valve was applied to the pipe net work of water supply system, as a result, we can traverse all pipe in pipe networks and find the control valves minimizing the area of which water supply is suspended. Therefore, the technique described herein could be convenient and effectively used for controlling valves when pipeline break accident occurred.

As yet, no comparative analyses have been conducted regarding the comparative antioxidant activities and HPLC profiles of thistles distributed in Korea. Thus, this study was performed in order to evaluate the antioxidant potentials of seven Korean thistles: Cirsium lineare, Cirsium chanroenicum, Cirsium setidens, Cirsium japonicum var. ussuriense, Cirsium nipponicum, Cirsium pendulum and Carduus crispus, via peroxynitrite and DPPH free radical assays. Among seven Korean thistles, Carduus crispus exhibited the most significant antioxidant activity in both DPPH assay and peroxynitrite. In order to characterize the compounds contained in Korean thistles, we conducted HPLC analyses on the following ten flavonoids: luteolin-5-glucoside (1), luteolin-7-glucoside (2), apigenin-7-glucoside (3), hispidulin-7-neohesperidoside (4), apigenin-7-glucuronide (5), cirsimarin (6), pectolinarin (7), luteolin (8), apigenin (9) and acacetin (10). The results of our HPLC analyses indicated the presence of pectolinarin in the whole plants of C. setidens, C. lineare, C. nipponicum, C. pendulum, the aerial and underground parts of C. japonicum var. ussuriense, and the aerial parts of C. chanroenicum. Moreover, we were able to identify hispidulin-7-neohesperidoside and luteolin-7-glucoside in the whole plants of Carduus crispus, acacetin in the aerial parts of C. chanroenicum, cirsimarin in C. lineare.
