Fixed point theorems for two hybrid pairs of single valued and multivalued noncompatible maps under strict contractive condition are proved, without appeal to continuity of any map involved therein and completeness of underlying space. These results extend, unify and improve the earlier comparable known results.

It is commonly found that liquid crystals stored in a common environment degrade with time, trapping more and more ion impurity in the materials. In this paper, we demonstrate how the electrical property of an old batch of liquid crystal can be effectively restored by a novel regenerative agent.

This paper is concerned with a flow-shop scheduling problem for all jobs having the common due date using V-Shape penalty cost function for earliness and lateness. The objective of the paper is to develop an efficient heuristic scheduling algorithm for minimizing total penalty cost function and for determining the optimal common due date. In addition, the between-job-delay for two machines are considered for developing the algorithm. A numerical example is given for illustrating the proposed algorithm.

In this paper we prove certain coupled coincidence point and coupled common fixed point results in partially ordered metric spaces for a pair of compatible mappings which satisfy certain rational inequality. The results are supported with two examples.

This study considers enlargement phenomenon in hair style as one of Costume types and analyzes its artistic characteristics based on the comparison between Hair style in the late Chosun Dynasty and that of the Rococo. First, its formative property, one of the common aesthetic characteristics, breaks the concept of traditional balance in Clothing and emphasizes its transformation, changes, and space beauty. This formative property shows the Enlargement and exaggeration beyond the concept of Space. Its sensuous property reflects women's psychological minds; exaggeration and sensualism. Artistic property doesn't focus on hair style only or clothing style only and considers hair style as renter of beauty as well as its important element. It shows the traditional beauty of nature and creativity in the Chosun Dynasty. Second, its formative property, one of the differential aesthetic characteristics, shows these following differences considering the aesthetic characteristics in the late Chosun Dynasty and that of the Rococo; mutual transformation, independent transformation, focus on distortion, harmony in scale, disharmony between irregularity and exception, extension and separation in space, etc. Sensuous property shows the temperate beauty and metaphorical sense, affected by the Practical Science, in the late Chosun Dynasty while it shows the secular sense and exaggerated beauty, affected by the Enlightenment, in the Rococo. Artistic property shows the harmony with the Clothing style, balanced wearing lines, and natural beauty, as one part of Clothing, in the late Chosun Dynasty. However it shows creativity, as separate part from Clothing, in the Rococo.

This paper quantitatively compares the intrinsic features of the daily USD-GBP exchange rates in two different periods, the 1920s and the 2010s, under the same freely floating exchange rate system. Even though the foreign exchange markets in the 1920s seem to be much less organized and developed than in the 2010s, this paper finds that both the long memory volatility property and the structural break appear to be the common intrigue features of the exchange rates in the two periods by using the FIGARCH model. In particular, the long memory volatility properties in the two periods are found to be upward biased and overstated because of the structural breaks in the exchange markets. Thus this paper applies the Adaptive-FIGARCH model to consider the long memory volatility property and the structural breaks jointly. The main finding is that the structural breaks in the exchange markets affect the long memory volatility property significantly in the two periods but the degree of the long memory volatility property in the 1920s is reduced more remarkably than in the 2010s after the structural breaks are accounted for; thus implying that the structural breaks in the foreign exchange markets in the 1920s seem to be more significant.

We study the theoretical background on the relationship between the equality property and operations treated in different sub-areas in secondary school mathematics curriculum respectively studied. Furthermore, we discuss in detail the equality property in rational numbers field $\mathbb{Q}$ and the real numbers field $\mathbb{R}$. Through this study, professional knowledges of school teachers are enhanced so that these aforementioned knowledges are connected smoothly to teaching activities in classrooms.

This article focuses on the legal systems and practice of intellectual property protection in Japan and China, including the relating civil litigation and administrative litigation procedures. The challenge of balancing the relationship between an invalidation trial and an invalid defense during the process of civil patent infringement litigation is a common issue to be solved in both Japan and China. In addition, it is quite usual that the IP products are being imported and exported across the borders due to the expansion of international trade. Accordingly, one of the most symbolic and difficult issues is how to balance the development of international trade and IP protection in each country. In other words, there is a practical issue regarding whether a parallel import of patented products is acceptable to a country or not. The key to determining this issue depends on the judgment of international exhaustion.

Brining property and antimutagenic effects of organically cultivaged Chinese cabbage kimchi (OC kimchi) and common Chinese cabbage imchi (CC kimchi) were studied. The salt absorption rate of leaves was faster than that of stems of the Chinese cabbages. Due to the large portion of leaf in organic Chinese cabbage, organic Chinese cabbage(OC) was much faster in terms of salt absorption rate than common Chinese cabbage(CC). The antimutagenic effects of methanol extracts of CC kimchi and OC kimchi were studied against aflatoxin B1(AFB1) using Ames test on Samonella typhimurium TA 100 and N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) using SOS chromotest. Methanol extract from 6 -day fermented OC kimchi at 15 $^{\circ}C$ showed 80% inhibition rate against the indirect mutage, aflatoxin B1 induced mutagenicit where as that from 6-day fermented CC kimchi at 15 $^{\circ}C$ showed 54% inhibition rate in the Ames test. Methanol extracts from 6-day fermented CC kimchi and OC kimchi showed 27 % and 58 % inhibition rate against direct mutagen , N-methyl-N'-nitro-N-nitrosoguanidine induced mutagenicity, respectively in SOS chormotest, thus OC kimchi exhibited higher antimutagenic activity than kimchi.

P & I Clubs are mutual and non-profit making insurers which offer shipowners cover for the contractual and third-party liabilities. Whereas most shipowners obtain P & I insurance to cover for their legal liabilities, they also obtain hull insurance to cover against damages to the hull of their vessels from commercial hull insurers. P & I insurance was distinguished from hull insurance in respect that it offered non-limited cover to shipowner member, but there was a serious debate between P & I Clubs in respect of the non-limited cover. A compromise by International Group of P & I Clubs eventually emerged under which, with effect from 20 February 1997, a financial cap was placed on the obligation of each shipowner to pay catasrophe calls to his club(20% of each ship's property limitation fund under 1976 Limitation Convention). Nevertheless many shipowners felt that this new cap on their potential catastrophe call had been set still too high, while others resisted any reduction in the figure established by the compromise. In the Meantime, the European Commission issued a Statement of Objections in June 1997, in which it indicated its objections with a compulsory single limit common th all the Group clubs as high as the 1997 compromise. Eventually the board of all the Group clubs decided that the figure of 20% of the Limitation Convention per ship property funds should be dropped down to 2.5% from 20 February 1999.
