The spatial variability in the food chain structure of an estuary environment (Nanakita estuary, Japan) was investigated using fatty acid. Potential organic matter sources (terrestiral plants, macroalgae, benthic microalgae, dinflagellates and bacteria), sedimentary organic matters and benthic invertebrates (Nuttallia olivacea and Nereidae) were sampled in four locations with different tidal flat type. The main objective of the present study was to determine the origin of sediment and the food sources of N. olivacea and Nereidae along with small-scale spatial variability. The origin of sedimentary organic matters were mainly the fatty acid of bacteria and benthic microalgae. Especially, The organic matter of terrestrial plant origin was found the highest in station C. The diets of N. olivacea and Nereidae were found to be dominated by diatoms and terrestrial plants. Whereas, macroalgae and dinoflagellates showed little influence to benthic invertebrates. Moreover, according to principal component analysis, it is showed that benthic invertebrates in the same region are using the same food without relation with species. On the other hand, the N. olivacea and Nereidae of station D clearly contrasts with station B in terms of main food sources. From these results, it is suggested that food competition of benthic invertebrates revealed high a connection between small-scale spatial variability and food source in estuary.

Main aims of this study are to clarify petrochemistry of the granitic gneiss in the Durye-Suncheon area. The origin of the metamorphic rock is evaluated from the abundance of $Na_2O$, the $TiO_2$/$Al_2O_3$ratios, the Harker variation diagram and $Al_2O_3$($Na_2O$ +$K_2O$ + CaO) ratios of the major elements. and the frequency distribution and average abundance of the trace elements . The trace elements of the granitic gneiss in the studied area are compared with those of the granitic rocks with shales in the other areas. The abundance of $Na_2O$ is lower than 3.27% and the $TiO_2$/$Al_2O_3$ ratio is 0.04. Also the Harker's variation diagram indicate this granitic gneiss correspond to sedimentary origin or S-type granite. The average abundance for trace elements of the granitic gneiss is similar to that of the shale, and the frequency distribution shows extensive distribution and irregularly . But xenolith are observed in the field survey, it is evidence of igneous origin , and then origin of the granitic gneiss in studied area is S-type granite.

This study examined the effects of social support on the perceived life satisfaction of middle-aged wives. To better understand the effects of social support on the perceived life satisfaction of middle-aged wives this study considered the following four different types of social support: emotional material informational and companionshp support. In addition each type of social support from the following five sources-the family of origin network the family of husband network friends neighbors and social organization-were examined separately in relation to the perceived life satisfaction of middle-aged wives. The data for his study were collected in the winter of 1995 from 417 housewives in Pusam wholse youngest child has graduated from elementary schools. Analyses of these data proved that (1) contrary to the classical "middle-age cristis" theory the average level of the perceived life satisfaction of middle-aged wives is relatively high; (2) there is a strong positive correla ion between the global level of social support and the overall life satisfaction of middle-aged wives; (3) the family of origin network is the most important provider of social support to middle-aged wives; and (4) the effects of social support on the perceived life satisfaction of middle-aged wives differ across types and sources of support. Findings showed that emotional informational and companionship support from the family of origin network have significantly positive effects on the perceived life satisfaction of middle-aged wives. On he other hand the material support from the family of origin network proved to have little effect.le effect.

The purpose of this study was to measure the estimated coefficient and marginal willingness to pay of attribute level: origin logo, origin description, traditional food, fusion food, service guarantee, and price, which influence tourist preference for restaurants. Also, the study identified the attribute which confers the highest importance to tourists. Conjoint experiment and the ordinal probit model were used for this study. A total of 210 surveys were conducted by tourists. The findings from this study were as follows. First, the effects of all attributes on tourist preference for restaurants were statistically significant. Second, tourists regarded an origin logo as the very important attribute, and were more willing to pay for the case where the menu contained origin logo. These findings suggested new marketing opportunities for restaurant managers. Although this study provides some evidence on the value of the local product brand to tourists, a similar measure has not been developed for local residents. This is an area in need of future research.

This paper deals with the question of the origin of polo. Although it is a sport that has been mainly active in the West since the nineteenthcentury, it is well known that British troops in the northern part of Pakistan learned about the sport from the local people there. Most agree that the origin of polo is Iran. However, in this paper, rather than specifying a specific area as the birthplace of polo, it is argued that polo was a cultural phenomenon commonly found on the Silk Road. This is based on the fact that polo has been known for centuries in China, the Korean Peninsula, and Japan, as well as throughout Iran, northern India, Tibet, Central Asia, and the Uighur Autonomous Region. Yet, the transmission of polo cannot be traced chronologically according to the supposed propagation route. This cultural phenomenon has changed over a long period of time according to the local environment, and the change was caused by mutual exchanges, not by one party. Therefore, there are limitations to interpreting cultural phenomena linearly. Thus, the origin of polo could also be identified with another area, namely Baltistan in modern day Pakistan, instead of Iran. These results support the argument that to understand Silk Road civilization, a process-centric approach based on 'exchanges', not a method of exploring archetypes to find 'the place of origin', should be utilized. Polo is undoubtedly an important cultural artifact with which to read the Silk Road as a cultural belt complex, as well as an example of the common culture created by the whole Silk Road.

Radio-loud active galaxies have been found to exhibit a close connection to galactic mergers and host galaxy star-formation quenching. We present preliminary results of an optical spectroscopic investigation of the AKARI NEP field. We focus on the population of radio-loud AGN and use photometric and spectroscopic information to study both their star-formation and nuclear activity components. Preliminary results show that radio-AGN are associated with early type, massive galaxies with relatively old stellar populations.

There has been an enormous increasing trend of widening gap of social inequalities since economic crisis at the end of 1997 in Korea. Since then, Korean society has deteriorated in economic and social conditions; the unemployment rate, temporary or casual workers and absolute poverty have increased. This paper presents the origin of inequalities in work and health in Korea. The origin of inequalities in work begins with the relationship between the capitalist and labourers in the capitalist mode of production. The conception and execution are dissolved in the work process in the capitalist mode of production. Thus, captitalists become control over ther labour process from workers. An alienation of the work process from the workers. The distribution of work is the majour source if inequalities in many countries as well as Korea. This paper presents the increasing tendency of unhealthy states such as mortality, early death, morbidity, physical work load, workplace injury amongst the under-privileged: ordinary workers, unemployed people, casual workers and socially deprived people in Korea.

Thermal deformation of machine origin of machine tools due to internal and external heat sources has been the most important problem to fabricate products with higher accuracy and performance. In order to solve this problem, GMDH models were constructed to estimate thermal deformation of machine origin for a vertical machining ceneter through measurement of temperature data of specific points on the machine tool. These models are nonlinear equations with high-order polynomials and implemented in a multilayered perceptron type network structure. Input variables and orders are automatically selected by correlation and optimization procedure. Sensors with small influence are deleted automatically in this algorithm. It was shown that the points of temperature measurement can be reduced without sacrificing the estimation accuracy of $\pm$5${\mu}{\textrm}{m}$. From the experimental result, it was confirmed that GMDH methodology was superior to least square models to estimate the thermal behavior of machine tools.

According to the literature, soybean cultivation originated from Wang-Gong (B.C. 685-643) of China who brought it from northeast Asia, for the first time. FUKUDA, of Japan divided soybean into three species-the wild, the cultivated and the intermediate. From the result of that study, he concluded that the soybean originated in northeast Asia. But Wang Kum Rung of China insisted that soybean originated in Hwa-Nam, because the soybean is a shortday plant and the agricultural history of Hwa-Nam, south of China, is older than that of northeast Asia. However, agriculture in northeast Asia had been already begun about B.C. 4000-6000 and the origin of culture cannot be decided only by photosensitivity. It has been proved that soybeans found in Korea were same as the ones of B.C. 2000. The soybeans of northeast Asia meet the conditions of the probable place of origin of cultivated crops established by Vabilov. Accordingly it is concluded that soybean has been originated from northeast Asia.
