  • Let G be a finite group. By a sequence over G, we mean a finite unordered sequence of terms from G, where repetition is allowed, and we say that it is a product-one sequence if its terms can be ordered such that their product equals the identity element of G. The large Davenport constant D(G) is the maximal length of a minimal product-one sequence, that is, a product-one sequence which cannot be factored into two non-trivial product-one subsequences. We provide explicit characterizations of all minimal product-one sequences of length D(G) over dihedral and dicyclic groups. Based on these characterizations we study the unions of sets of lengths of the monoid of product-one sequences over these groups.

  • Objectives: The aim of this study was to compare the cyclic fatigue resistance of the WaveOne Gold Glider, ProGlider and One G glide path instruments in artificial doublecurvature canals. Materials and Methods: This study included 15 WaveOne Gold Glider (size 15/0.08), 15 ProGlider (size 16/0.08), and 15 One G (size 16/0.06) nickel titanium files. The files were used in accordance with the manufacturer's instructions until they were broken in artificial double-curvature canals made of stainless steel. The time to fracture was recorded via a digital stopwatch and the number of rotations until fracture was also calculated. The data were statistically analyzed via the Kruskal-Wallis test. Results: The highest average number of rotations until fracture of the files was found for the WaveOne Gold Glider, followed by ProGlider and One G in order. Statistically significant differences were present between all groups of files (p < 0.05). Conclusions: In our study, the resistance of the WaveOne Gold Glider nickel-titanium (Ni-Ti) file to cyclic fatigue in S-shaped curved canals was found to be higher than that of the ProGlider and One G Ni-Ti files.

  • Well-balanced meal is very important in its quantity and quality. Especially on the quantity field it becomes difficult for a foodservice operation to decide proper portion for individuals uniformly. These study was focused to setting up a proper portion by each food service operation. The results obtained were: 1. Individual consumption size from dormitory food service of college: cooked rice 282 g, soups 161 g, pot stewes 162 g, stir fries 53 g, stews 32 g, kimchies 47 g, fresh and boiled salads 43 g, one course dishies 477 g, pan broiles 44 g, meunieres 124 g. Individual consumption size from industry foodservice (white collar worker): cooked rices 228 g, soups 205 g, pot stewes 251 g, stir fries 20 g, stewes 76 g, kimchies 57 g, fresh and boiled salads 36 g, one course dishies 423 g, pan broiles 63 g, meunieres 38 g. 2. Proper portion of meal based on a statistical data is as follows: at college foodservice - cooked rices $280{\sim}290$ g, soups $155{\sim}170$ g, pot stewes 170 g, stir fries 60 g, stewes 35 g, kimchies $40{\sim}60$ g, fresh and boiled salads 50 g, one course dishies 480 g, pan broiles 50 g, meunieres 130 g and at industry foodservice (white collar worker) - cooked rices $220{\sim}250$ g, soups 210 g, pot stewes 250 g, stir fries 20 g, stewes 80 g, kimchies 60 g, fresh and boiled salads 40 g, one course dishies 430 g, pan broiles 70 g, meunieres 40 g.

  • In order to convert the one ryang of Guizhi-tang into the modern weights and measures, herbs whose dose was expressed by number in Treatise on Feverile Disease of Zhongjing were measured actually. The results obtained are as follows. 1. Size of Jujubae fructus in Guizhi-tang is an average and if remove the seed, 12 Jujubae fructuses corresponds to 20g. These weights are the same as Belamcandae Rhizoma, Persicae Semen, Gleditsiae Fructus, Gardeniae Fructus and Armeniacae amarum Semen whose dose was expressed by number in Treatise on Feverile Disease of Zhongjing. If one ryang corresponds to 6.5g, 20g corresponds to three ryang. If one ryang corresponds to 15.6g, 20g corresponds to 1.3 ryang. When herbs were added in Guizhi-tang, the used weights were two more ryang. Almost unit of weights in Formulae of Zhongjing is the constantly multiplied. 2. Half sheng(升) of Pinelliae Rhizomae is 15 Pinelliae Rhizomas and corresponds to two and a half ryang. 14 Pinelliae Rhizomas are contained in 50 mL egg. 3.1 geun(斤), maximal amount of Gypsum Fibrosum and amount of one egg are the same weight supposing one ryang corresponds to 6.5g. 4. 2 ryang of Rhei Radix et Rhizoma is the 6.8 balls(碁子) of baduk and similar as 5-6 balls of baduk of Jisilchijasi-Tang. 5. General dose of Glycyrrhizae Radix is two ryang and 20mL, the size of thumb is 13g. 6. Half geun approaches the 3 flattened spoons. Consequently the presumption that one ryang in Guizhi-tang is 15.6g is wrong. One ryang is assumed as 6.5g.

  • Selecting appropriate G values in flocculator operation is important to produce high quality filter effluent in water treatment plants. However, misunderstanding and misleading of G calculation for the case of having power sources more than one or many paddles with one power source in a flocculation basin sometimes have led to low performance in flocculation. Theoretical analysis confirmed that the total G value in one flocculation unit having power sources more than one or with many paddles is the root-square of the sum of square of individual G value. This analysis also can give a simple calculation method of G value for designers and operators in fields.

  • We prove that if a graph G of bounded degree has finitely many p-hyperbolic ends($1) in which every bounded energy finite p-harmonic function is asymptotically constant for almost every path, then the set $\mathcal{HBD}_p(G)$ of all bounded energy finite p-harmonic functions on G is in one to one corresponding to $\mathbf{R}^l$, where $l$ is the number of p-hyperbolic ends of G. Furthermore, we prove that if a graph G' is roughly isometric to G, then $\mathcal{HBD}_p(G')$ is also in an one to one correspondence with $\mathbf{R}^l$.

  • Let G be a connected graph. A pebbling move on a graph G is taking two pebbles off one vertex and placing one of them on an adjacent vertex. The pebbling number of a connected graph G, f(G), is the least n such that any distribution of n pebbles on the vertices of G allows one pebble to be moved to any specified, but arbitrary vertex by a sequence of pebbling moves. In this paper, the pebbling numbers of the lexicographic products of some graphs are computed.

  • Let $K_{\alpha}(G)$ (resp. $K_s(G)$) be the abelian (resp. symmetric) Kac algebra for a locally compact group G. We show that there exists a one-to-one correspondence between the subgroups of G and the sub-Kac algebras of $K_{\alpha}(G)$ (resp. $K_s(G)$). Moreover we obtain similar correspondences between the subgroups of G and the reduced Kac algebras of $K_{\alpha}(G)$ (resp. $K_s(G)$).

  • This experiment was conducted to investigate the effects of growth retardant uniconazole on the growth and flowering of Cymbidium Pine Clash 'Moon Venus' and Cym. Green Sour 'A One'. Reduction in leaf length of both cultivars was proportional to the amount (0-5g) of uniconazole and growth reduction of 'A One' was more remarkable than 'Moon Venus'. The inflorescence length was reduced 18.4% in 'Moon Venus' and 15.3% in 'A One' by 5g treatment of uniconazole. There was no significant difference in flowering time, number of inflorescences and florets and size of lower sepal regardless of uniconazole treatment. It was concluded that uniconazole treatment is effective in reducing the leaf growth of Cymbidium. However, as high concentration (5g) of uniconazole reduced the growth of inflorescence causing low quality, 1g was recommended as useful concentration.
