This experiment was carried out to study the effects of nitrogen concentration of cultural solution, rhizobium inoculation, and planting density on nodulation, contents of total-N and allantoin-N of the plants, and contents of crude fat and protein of the seeds with 4 cultivars and 1 non-nodulation isogenic line (Hwangeumkong, Jangbaegkong, Paldalkong, Clark, non-nodulating Clark) in nutri-culture. Modulation was increased significantly by the rhizobium inoculation and decreased by the increase of nitrogen concentration of the cultural solution and planting density, and more nodule per plant was observed in Hwangeumkong than other cultivars. Total nitrogen contents of the soybean plant were higher in Hwangeumkong and Janbaegkong compared with other two cultivars, and were increased by rhizobium inoculation and the increase of nitrogen concentration of the cultural solution except in case of $R_3$ stage of non-inoculation of rhizobium, and was decreased by the increase of planting density. Allantoin nitrogen contents of stem were lower in Paldalkong compared with other cultivars and was increased significantly by the rhizobium inoculation, and thus was correlated significantly with nodulation. Allantoin-N contents were also decreased by the increase of planting density and nitrogen concentration of the solution, and was very low in case of non-nodulating isogenic line at any level of nitrogen concentration. The contents of crude fat of the seed were lower in cases of higher nitrogen concentration of the solution and more plants per pot, but no effects of rhizobium inoculation was observed. The contents of crude protein were tend to increase by the increase of nitrogen concentration, but were little effected by rhizobium inoculation and planting density.

The current situation and problems of sensory console games was analyzed focusing on the Nintendo 'Wii.' In order to develop the limitation of contents that lean strongly towards sports and fail to offer diversity one step further into glocal cultural contents, a solution of applying 'Bollywood,' which has a main musical format, is presented. Bollywood is a unique cultural code of India which can stimulate the purchase desires of consumers with its exotic freshness in third countries, and can be used to lead sales of a new form of game culture that is familiar yet in a new format in the 1.1 billion population Indian market. The political, social and economic codes of Bollywood are examined in this study in addition to cultural contents and codes that include Bollywood to develop contents that are not foreign to their culture.

The fruiting body of Paecilomyces sinclairii was collected in Baekyangsa, Jeollanam-Do, Korea. Cultural conditions for the mycelial growth and fruiting body formation were investigated. Its optimum mycelial growth was obtained at 25℃ and pH 8 on potato dextrose agar and Hamada media among the various media tested. The carbon and nitrogen sources for the optimum mycelial growth were dextrin and glutamine, respectively. The optimum C/N ratio was about 20:1 in case that 1% glucose was supplemented to the basal medium as a carbon source. The favorable mycelial growth was obtained from corn meal extract medium mixed with 30% (w/v) milk solution. The maximum fruiting body was formed in unpolished rice medium supplemented with 20% (w/w) silkworm pupae at $25^{\circ}C$ under 500lux.

The influence of noxious corrosive gas, which is the product of fossil fuel, and the acidic descent material, which becomes the reason for such reaction, on wax which protects the cultural assets, and the habitat factor were researched. It could be viewed that corrosion occurred rapidly due to the acidic descent material, which have the long staying on the material, rather than harmful corrosive gas. Also, it could be figured out that such corrosion began from whitening phenomenon of coated wax. As the acidity increased, more whitening phenomenon occurred, and eventually, it could be found out that whitening effect began due to the acidic descent material, corrosive gas and various 0.1 M acid solution, which lead to the exposure of internal metal, and corrosion occurred. The wax with the greatest resistance to the acidity due to its least changing aspect seemed to be Renaissance wax, except sulfuric acid.

Bacteria with ability for iron reduction in the soil can use corrosion products of iron remains as energy source. The activities of this bacteria cause the change of corrosion products. As a result, it can be difficult to identify corrosion products promoting corrosion of iron remains. The purpose of this study, is to investigate the change in corrosion products that bacteria causes and to improve understanding about the corrosion of iron remains. To simulate corroded condition of excavated iron remains, carbon steel corroded by solution of NaCl and $Na_2SO_4$ was prepared. Then the prepared carbon steel was immersed in a liquid medium with bacteria. The incubation period was 42days. After experiment, the carbon steel was analyzed by SEM-EDS, X-ray diffraction method. The result is that the carbon was changed to green because of activity of bacteria and that the plate crystal and lozenge crystal were generated on the corrosion specimen. Also, we confirmed that the activities of bacteria differenciated colors and forms of corrosion products.

Excavated archaeological cast iron objects in improper storage are quickly corroded and disintegrated into block and powder finally. Hence desalination treatment which is a way of removing internal corrosive factors, especially chloride ion, is an important process. But desalination is often omitted or objects are dehydrated by alcohol because the destruction of objects could occur during desalting. Although current desalting methods mostly use an aqueous alkali solution, $OH^-$ ions of water could accelerate corrosion and broaden internal cracks cause of high surface tension. Therefore this study experimented desalting using ethyl alcohol, which is low surface tension, to investigate an effect of desalination. As a result, desalting using ethyl alcohol showed the similar or more effective results of desalting using water. In addition, as aspects of desalting safety, ethyl alcohol desalting method was smaller destruction of objects and extraction of Fe from the objects than the aqueous alkali solution. However, this study explored the possibility of desalting methods using organic solvent in fieldwork, so the results would provide basic date for making the safe and effective desalting method for archaeological cast iron objects through further experiments.

The feasibility of the geopolymer as a cultural asset restoration material was studied by investigating compressive strength and chromaticity change. Metakaolin that was synthesized by calcination of the kaolin at $750^{\circ}C$ for 6 hours was used as a geopolymeric starting material. Kaolin lost its crystallinity and changed into non-crystalline phase during calcination. NaOH solution and water glass were used as an initiator for the geopolymeric reaction. As the concentration of NaOH solution and water glass increased the compressive strength increased. When alumina was substituted with metakaolin, the compressive strength decreased at a small amount of alumina, but increased at a large substitution. For the most composition of geopolymers, the change of chroma values remained within the limit of slight variation after exposure to sunlight for 8 and 100 days. However, even small amount of organic pigment addition increased chroma values of metakaoline. It was shown that geopolymer had excellent chroma value change over epoxy resins.

This is a study of George Lindbeck's postliberalism that views religion as a cultural-linguistic approach. Knowing that the conceptual-propositional approach of the traditional Christian theology and the experiential-expressive approach of liberalism cannot be a solution for the post-modem religious phenomenon, George Lindbeck proposes an alternative. He proposes a cultural-linguistic approach to overcome the previous approaches. The first insight of Lindbeck's postliberalism is to understand religion as culture or language, because human beings become acquainted with a religion as they learn a language. The second insight comes out of the first, to understand doctrine as grammar. If we understand religion and doctrine this way the troubles and conflicts among religions will be resolved naturally, because each religion can be interpreted in its own system just as a language cannot be said to be good or bad, right or wrong. This approach makes several contributions as follows: it promotes a dialogue among religions, it emphasizes practice; and it preserves the Bible as an authoritative theological text. However it also brings many limitations as follows: it emphasizes the church's interpretation rather than the text's own interpretation; it views the truth simply as coherence; it promotes radical relativism and elitism; and through theological eschatology he makes his theory return to a propositionalism. Accordingly, the researcher concludes that Lindbeck's cultural-linguistic theory of religion is not an alternative that overcomes the limitations of theological conservativism and liberalism.
