The purpose of this paper is to analyze the effect of users guild system on game community activation. For the analysis, the paper used 2,876 users data of online game 'Gunju(Monarch)'. Social support between gamers who belong to guilds was more influential to community activation than that of gamers who doesn't belong to guilds. Especially, the fact was found that social support between guild members (internal social support) plays more important role on community activation than that between guild members and non guild members (external social support).

Polychaetous community survey in Tomioka Bay was carried out 5 times seasonally from May 1991 to March 1992 by quantitative grab sampling (0.05m2) at 11 stations. Based on the granulometric composition and environmental factors, a homogeneous soft bottom was found in St.5-10. The species of the polychaete were classified into three feeding groups using the Fauchald and Jumars' feeding guild system. According to polychaetous community composition data, deposit feeders predominate in sandy silt area where the silt-clay content is $60-69.3\%.$ These deposit feeders were subdivided into surface deposit feeders and subsurface deposit feeders by their living position and mode. Also, suspension feeding group comes as the third dominant group. Seasonal changes of each feeding group were described in terms of numerical density and biomass. Feeding layer and types of dominant species (Lumbrineris longifolia: surface deposit feeder; Praxillella pacifica: subsurface deposit feeder; Chone duneri; suspension filter feeder, etc.) were examined in the intact sediment core samples. Also, longterm density change among the three dominant species during 10 years was disussed.

The oversea export of agricultural-product about item and quantity has not increased recently; especially the fresh-product has a tough issue because of period of production, price large fluctuations, customs clearance, quarantine, and uncertainty about actual locality, we need the information based construction to exchange information quickly about whole range of export and to focus capacity of participation subject for increasing the export. In this study we design the agricultural-product transaction information system based on crowdsourcing to transact the agricultural-product and the information of influencing benefit directly, and the information offering about export-procedure from participation of customs clearance, finance, distribution, buyer, and producer's guild, etc. We expect the producer's guild about agriculture that has not participate the trade to be able to export the agricultural-product and the stabilization of price to transact the product of collapsed or boomed through the agricultural-product information system based on crowdsourcing.

The objectives of the study were to determine fish fauna and compositions during 2010~2011 in Walpyung Conservation Park along with analysis of fish community structures and trophic and tolerance guilds. Total number of species and individuals sampled were 31 and 2667, respectively and dominant species was Zacco platypus (46.6%) and subdominant species was Acheilognathus lanceolatus (8.7%), which were composed of >50% of the total. Total number of Korean endemic species including Microphysogobio yaluensis was 10 and the proportion of the individuals was 8.7%. Also, natural monument No. 454 of Iksookimia choii, which is endangered species and legal protected species, was sampled and the total number of individuals was only three. According to the analysis of fish community structures, species richness index in the mid-stream reach ($M_r$) was 3.145, which is higher than any other stream reaches ($U_r$ and $D_r$). In contrast, the richness index was 2.180 in the up-stream reach ($U_r$), which is minimum among the sampling sites. Species diversity index was 1.785 and 1.975, respectively in the headwater ($U_r$) and mid-stream reach ($M_r$) and the low values in the down-stream reach ($D_r$, 1.660) were due to the influences of pointsource (i.e., road construction) and non-point sources (sporadic agricultural spots). According to analysis of tolerance guilds, the proportion of tolerant species (TS), based on the number of individuals, was composed of 64.2% and sensitive species (SS) was only 3.3%, indicating a predominance of tolerant fishes in the compositions. The proportion of omnivore species (OS), however, was composed of 64.0% and insectivore species (IS) was 29.3%, indicating a predominance of omnivore fishes in the stream. The high proportions of tolerant and omnivore species in this stream indicates that the water quality and physical habitat environments were degradated in this system. For these reasons, especially natural monument and endemic fish species in this region should be protected from the massive constructions and required to provide efficient stream management strategies.

This paper critically studies Meidner's wage-earner funds project. On the basis of this, this paper intends to create new prospects for a universal welfare regime. From the perspective of the welfare system, the funds project is a correction or supplement of the Swedish welfare system of the Swedish model centered on 'redistribution'. However, the funds project shares the ideology of Swedish model and its fundamental premise, I.e. guild socialism and labor-centrism. This paper discusses the limitations of the funds project resulting from this, especially with regard to its three purposes: equalization of property distribution, economic democracy and the correction of excess profit. It then highlights that the alternative to overcome the limitations of the funds project and the Swedish universal welfare system should be based on a new ideology and fundamental premise that is cut off from guild socialism and labor centrism. As an alternative fulfilling this, this paper focuses on theories that suggest that the Common Wealth Fund should be created and basic income should be implemented in the form of dividends as its dividend. As a result, Commons Capital Stock and the basic income as its dividend are presented as alternative prospects for the funds project.

The objective of this study was undertaken to investigate changes in fatty acid profile of breast and thigh muscle of old laying hens as transferred from cage to backyard raising system and to provide basic information on using old laying hens to producers for environmental managements. Overall, percentages of unsaturated fatty acid obtained from breast and thigh muscle with cage and backyard raising system are the most abundant, followed by saturated fatty acid. For breast muscle, there were no differences (P>0.05) between cage rearing system and backyard raising system in saturated fatty acid (SFA) and mono unsaturated fatty acid (MUFA). Poly unsaturated fatty acid (PUFA) and PUFA:SFA ratios were significantly higher in backyard raising systems in comparison with cage rearing systems (P<0.05). No differences (P>0.05) were detected between both rearing systems for MUFA, PUFA, and PUFA:SFA ratios with thigh muscles. SFA in thigh muscle was significantly (P<0.05) higher in cage rearing systems compared with backyard raising systems. In conclusion, using breast and thigh muscle meats from old laying hens as functional foods or investigating impact assessment on the improvement of farm management system may serve as a good management practice to encourage producers.

This study was to analyze characteristics of fish compositions and longitudinal distribution, based on trophic and tolerance guild at 22 sampling sites of Yeongsan River watershed during 2003$\sim$2006, and also to compare before and after the estuary dam construction. The collected fishes, based on catch per unit effort (CPUE), were 44 species in the watershed and dominant fishes were Zacco platypus, Acheilognathus macropeterus, Zacco temminckii and Carassius auratus. According to comparative analysis of fish in the non polluted sites (NPS) vs. polluted sites (PS), the number of species and individuals was lower by 70% in the PS than the NPS, indicating ecological degradations by chemical pollutions or/and habitat modifications. The relative abundance of sensitive and insectivore species decreased as the stream order increases, while tolerant and omnivore species increased with the stream order. In this survey, largemouth bass (Micropterus salmoides), which is a top-carnivore and exotic species, may influence trophic guild system throughout active predations on endemic species, resulting in modifications of ecological functions. The construction of estuary dam on Yeongsan River in 1981 resulted in wider lacustrine zone and desalinated through limitation of seawater input. These physical changes have caused increases of lentic dwelling species and limited fish migrations (i.e., eel). Overall, fish fauna and composition analyses showed that the number of species and individuals in this water body may be reduced due to inputs of pollutants from the watershed, habitat modifications, and increases of exotic species (largemouth bass). For these reasons, effective lake management strategies are required for the ecosystem conservation.

This study is the first research that examines the fashion manufacturers and merchants of the late 18th century France. Fashion specialists, (known as) Marchande de modes, started to appear in literature in the mid 18thcenturyandthe profession was officially recognized by the guild system in 1776. Rose Bertin was elected as the first representative. At the same time, there were two types of fashion specialists, tailleur and couturi${\grave{e}}$re. Tailleur had monopolized the production of the bodice and the skirt, which were the most important female dress parts. On the contrary, couturi${\grave{e}}$re only had the right to make petticoats, but they were not allowed to decorate it. In 1781, the couturi${\grave{e}}$re obtained the right to make and decorate the other parts of the dress, and this resulted in the two groups fighting over the rights to make dresses. And during this struggle, the Marchand de modes started to appear as a new occupation. Marchande de modes were privileged fashion merchants making or selling trimmings for dress and coiffure, and had authority to make capes and bonnets. Contemporary critics praised their talents for creating innovative and beautiful fashion styles, while some criticized them as women who just made luxury items. These records revealed how marchande de modes were viewed during that time.

The construction method of scaffolding structures is different from Mortise and Tenon and bucket arch structure of traditional large woodwork. It forms an independent construction system-fixing nodes with knots, a large number of diagonal braces are used to fix shelves and the structures mostly contain X-shape and triangular shape details. Simple ones include stalls, sheds, rain sheds, altars, lamp racks etc. But the scaffolding with larger scale and more complicated structure are modeled on archways, theatres and other buildings which are used in commercial and festival activities. At present, Macao, Hong Kong, Guangdong, Sichuan, Shanxi and other places in China have retained the custom of using scaffolding structures in important festival activities, but their uses, techniques and building types are slightly different from place to place. Due to building and demolishing at any time, the construction and service cycle is short. As a result, there are almost no physical objects left. We can only deduce the use and technical characteristics of ancient scaffolding skills through the colorful building styles that have been preserved with folk activities in various parts of China, the craftsmanship handed down from generation to generation by the scaffolding guild and artisans, and the description of cultural and historical materials and the mutual corroboration of visual materials.
