  • Safety is built in to the activities of the prudent ship operator. Ant investment made towards this end is likely to have a measurable payback in positive terms. That there must be an investment is inevitable, because the industry at large has let things slip too far too long. Those who have not allowed it to slip too far and who are the first to recognize that safety, far from costing money, in the long term actually preserves it, will be wieners. Too many seem to have lost sight of the fact that every one hundred pennies saved is a full one hundred pennies profit. Every hundred pennies of additional revenue contributes no more then fifteen pence to profit. Environmental protection is not so simple, nor so financially attractive. Man needs the minerals of the Earth as well as the products of the soil and sea survive. We(the human race) are still not in the position, politically or financially to manage the Earth's assets without causing damage. The evidence of our damage is evident in many different parts of the Glove and will in some cases haunt several generations still to come. We have learned a lot, and continue to learn, but despite the best intentions some Government needs for their people will be at the expense of people in another region for the foreseeable future. We sailors ply the seas with the raw materials of commerce as well as the finished and part finished goods. It does not always sit well to consider too deeply what effect the ship and the cargo it carries is having, or may have, on some communities, or on the sea through which sail. None my generation can hold up his head and claim to be without blame in the pollution of the seas. Times are changing though, and Governments are turning their attention more to the protection of our planet and its precious resources. This will not be without cost. The investment will have to be made not for our benefit, but for the benefit of generations yet to come, however the cost will have to be borne by society as a whole, not by the shipping community alone. The debate surrounding the choice between engineering our way to a better tomorrow, or adapting our working practices will continue. Each method has the same goal as its target and as long as we attain the goal does it really matter how we get there?

  • Kojongsi persimmon (Diospyros kaki L.) is the major cultivar of dried persimmon in Korea. The purpose of this study was to investigate the antioxidant and anti-inflammatory activities of water-soluble extracts from the calyx (PCE), peel (PPE) and leaf (PLE) of Kojongsi persimmon. PCE showed the highest total phenolic and flavonoid contents. In addition, the antioxidant activities (diphenylpicrylhydrazyl, 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid), nitric oxide and reducing power) of PCE were higher than those of PPE and PLE. Moreover, PCE, PPE and PLE significantly suppressed the production of inflammatory mediators (nitric oxide and $prostaglandinE_2$) and pro-inflammatory cytokines (tumor necrosis factor-${\alpha}$ and interluekin-$1{\beta}$) by lipopolysaccharide-stimulated RAW 264.7 cells in a dose-dependent manner. PCE showed the highest anti-inflammatory activity. Thus, these results suggest that the calyx of Kojongsi persimmon may be highly valuable as a natural product owing to its high-quality functional components as well as its-antioxidant, ant-iinflammatory activities.

  • The total amount of dry matter for the green manure crops was great wheat> rye> barley> Italian ryegrass in that order. The green manure crope were verified to have the reducing effect of injury of successive croppingin peper, mainly reducing the occurance of the most important pepper disease, Phytophthora capsisi, and enhancing the pepper quality in the fruit length and diameter. The direct seeding using current commercial pepper variety was proved as not economical one. In the first year of compost application, the growth and yield of red pepper were rather somewhat decreasing compared with those of check plot applied with organic fertilizers. compst application increased the content of organic matter in soil, which suggested compost could be applied for the sustainable purposes. In preference analysis about taking the new technique, the smaller farmer's cultivation area the more they wanted to accept the LISA farming, compared with the conventional one, could be possible to save 12% in the inorganic fertilizer expenses but wasted 412% ant 163% in both organic fertilizer and operator labor expenses, respectively. At the same time, the LISA decreased 15% in production cost but increased 225% and 139% in organic fertilizer quantity and operator labor hours. Since there was a great deal of difference in technological and economic factors from two farming methods, LISA multi-goal decision modeling is further required.

  • Transverse rib web of orthotropic steel decks is highly susceptible to stress concentration due to out-of-plane and oil canning deformation caused by longitudinal rib distortion. In particular, stress concentrations are observed in the crossing point of longitudinal rib-transverse rib-deck plate, and cutout parts of transverse rib. The main objective of this study is to improve structure performance and to reduce the stress concentration of aforementioned susceptible parts. It is known that the installation of diaphragm alleviates stress concentrations between crossing point ant cutout. The influence of transverse rib placement and cutout width on stress concentrations was thoroughly investigated through numerical analyses. The numerical result showed that diaphragms produce the structural details for improved structure performance, when the transverse rib was placed in the same location with diaphragms. In any case, it is certain that the installation of diaphragms has more advantageous than the case without diaphragms in terms of structure performance of orthotropic steel decks. In this study, the distance ratio($y_i/y_{total}$) is defined as the ratio of the distance($y_{total}$) between the deck plate and longitudinal rib bottom to the distance($y_i$) between the deck plate and crossing point of longitudinal rib-transverse rib in cutout part. It has been found that the optimal distance ratio was 0.85 from the numerical simulation.

  • Satae cheon, a tributary of the Suip cheon in Yanggu, Gangwon province, is an international river extended to North Korea. Most of drainage basin area of the river was the fierce battle field during the Korean War(1950-1953) and hard to access as it located between the MDL(Military Demarcation Line) and the CCZ(Civilian Control Zone: about 10km south from MDL). By the restriction of access to the sites, most of natural landscape have been well conserved except limited use for military activities. Even the landfoms in that area were not studied, except the government's heritage reports. Satae Cheon's channel follows the Imdang fault line(N-S) to Satae-ri and flow to west to the Dutayeon area. The river meanders along geological structure or weak line at the Dutayeon area. The meandering channel was shorten by the meander cut which linked the thalweg line of meander loop ant the meander neck. As a result of this cut, the river cliff formed by the Satae cheon became the part of newly formed channel bed and the S-forms are formed. After the channel route stabilized, channel incised the rock with large potholes and undulating walls were formed. The channel width changes from 1m to 10m with restriction of the undulating walls, so this part can be regarded as inner channel or inner gorge. From the point of planar forms it also can be slot-type canyon.

  • Die heutigen Experimente, die seit fast 20 Jahren in den Theaterbereiche $durchgef{\ddot{u}}hrt$ werden, sind so verschieden, $da{\ss}$ wir gar nicht voraussehen $k{\ddot{o}}nnen$, wieweit sie ihre Grenze mehr erweitern werden. Sie brechen alle vertrauten theatralischen Konventionen, ob diese Konventionen mit Text, Schauspielkunst oder Raum usw. zu tun haben. Und sie fragen sich selbst, was Theater in der heutigen simulierten Gesellschaft bedeuten soll. Die vorliegende Arbeit untersucht anhand einigen $Auff{\ddot{u}}hrungen$, die von solchen Selbstbefragen ausgehen, wieweit sie sich von den tradtionellen Theaterabeiten entfernen und welche neue $Theater{\ddot{a}}sthetik$ sie herzustellen versuchen, um der $gegenw{\ddot{a}}rtigen$ Gesellschaft, besonders nach 1990 Jahre, zu entsprechen. Nach dem Zusammenbruch des Ost-Blocks hat sich die Welt radikaler denn je $ver{\ddot{a}}ndert$. Durch die $revolution{\ddot{a}}ren$ Technologien wie Mobilfunk und Internet verwischen sich die Grenzen zwischen Wirklichkeit und Fiktion, zwischen Original und Nicht-original mehr und mehr. Die letztliche globale Finanz- und Wirtschaftskriese hat die ganze Welt in Schockzustand versetzt, aber man scheint bei den verschiedenen Schreckenzeneraien und den negativen Meldungen daraus noch keine "Lehre" gezieht zu haben. Die Experimente, die in dem Bereich der zeitigen Theaterarbeiten gewagt werden, sind die Versuche, die Theater selbst macht, um eine den radikalen gesellschaflichen $Ver{\ddot{a}}nderungen$ entsprechende neue $k{\ddot{u}}nstliche$ Aufgabe zu suchen. In dieser Arbeit $m{\ddot{o}}chte$ ich sie, $ant{\acute{i}}-theatralische$ Strategien nennen, weil sie jenseits der konventionellen theatralischen Arbeitsweise liegen. Diese $R{\ddot{a}}ume$, wo solche $Auff{\ddot{u}}hrungen$ gespielt werden und $nat{\ddot{u}}rlich$ auch den Zuschauerraum $einschlie{\ss}en$, sind, die $R{\ddot{a}}ume$ des Abwesenheit und des Abweichens,,, weil sie dem $gew{\ddot{o}}hnlichen$ Wunsch des Publikums, alles zu sehen, entgegenkommen. Sie fordern dem Zuschauer, der auch zu ihren wichtigen theatralische Element $geh{\ddot{o}}rt$, $da{\ss}$ er an ihren $Auff{\ddot{u}}hrungen$ mit den ganz anderen Sichtweise als den ${\ddot{u}}berlieferten$ aktiv, teilnehmen, $mu{\ss}$. Sie wollen ihre $Auff{\ddot{u}}hrungen$ zu den $Erfahrungsr{\ddot{a}}umen$ machen, wo der Zuschauer ${\ddot{u}}ber$ sich und sein eigenes Leben selbst reflektieren kann, indem er die wahrgenommenen Ereignisse zu seinen eigenen Erfahrungen $zusammenf{\ddot{u}}gt$.

  • Beta glucan was purified from Phellinus baumii and tested for its effect on the group performance of ants, a principal model of eusociality and of superorganisms. Japanese carpenter ants (Camponotus japonicus) were reared on diets containing beta glucans to characterize their effects on eusociality. Culturing structures for ants were assembled by implanting autoclaved soil into polyethylene terephthalate bottles. Three different eusocial strength indices were used to study the effect of beta glucan extract (BGE) on eusocial activities - the number of residence chambers, cooperative defense index (CDI), and group size and composition. Control, low- BGE, and high-BGE diets were prepared with the following three levels of BGE supplements in sucrose powder: 0, 20, and 50% (g/g). More residence chambers were observed in the BGE-fed groups than in the control. The CDI against a foreign queen ant was calculated according to the time taken to subdue the foreign queen. The high-BGE group took less time to complete their defense formation than the other groups. Differences were evident between control and BGE-fed groups in the total numbers of ants and eggs. The BGE-fed groups showed a significant increase in both the number of workers and the number of eggs. When fed with BGE, ants responded positively for all three eusocial strength indices. These results show that BGE exerts beneficial effects on the eusociality of ants as a superorganism.

  • Built upon ethnographic method such as participant observation and in-depth interview, this study analyzes the material culture of electronic flower auctions at Yangjae Flower Market. From the viewpoint of Actor-Network Theory(ANT), this research examines how human actors like dealers and auctioneers interact with nonhuman actors such as market devices and these interactions form networks called "agencement." This research is focused on three main objectives: first, to study how the performance of auctions - i.e. the interactions between auctioneers and dealers - change in the wake of new market devices in the auctions; secondly, to look into what changes artifacts bring to the social relationships between auctioneers and dealers; lastly, to analyze the influence of new market devices on auction price in the market. The results of this research are as follows. First, the appearance of new market devices generates changes in the performance of auctions, which means the change of 'agencement' of flower auctions. Direct interactions between auctioneers and dealers turned into indirect interactions through new market devices. Moreover, the changes in the agencement brought changes to the identity of auctioneers and dealers. Secondly, the new agencement caused by the inflow of new market devices formed the trust between the devices and human actors, which gave rise to the trust in electronic auction and in counterpart actors as well. In addition, new market devices lowered direct interactions between auctioneers and dealers and thus made more equal relationships between the two than before. Lastly, market devices like trading screen reduced the leverage of auctioneers by providing dealers with bidding information previously possessed by auctioneers much openly and dealers were able to decide auction prices in more reasonable and dispassionate manner. Economic agency, power, trust, price, and information in the market is material and sensory.

  • Among the numerous duties of a librarian in a library, the work of arranging books is a job that the librarian has to do one by one. Thus, the cost of labor and time is large. In order to solve this problem, the interest in book-arranging robots based on artificial intelligence has recently increased. In this paper, we propose the K-ACO algorithm, which is the shortest path algorithm for multi-stops that can be applied to the library book arrangement robots. The proposed K-ACO algorithm assumes multiple robots rather than one robot. In addition, the K-ACO improves the ANT algorithm to create K clusters and provides the shortest path for each cluster. In this paper, the performance analysis of the proposed algorithm was carried out from the perspective of book arrangement time. The proposed algorithm, the K-ACO algorithm, was applied to a university library and compared with the current book arrangement algorithm. Through the simulation, we found that the proposed algorithm can allocate fairly, without biasing the work of arranging books, and ultimately significantly reduce the time to complete the entire work. Through the results of this study, we expect to improve quality services in the library by reducing the labor and time costs required for arranging books.
