  • Three kinds of anti-complementary system and macrophage activating polysaccharides, AB-20-Ia, AB-20-IIa-2a and AB-20-IVa-2 were isolated from the fruit body of Agaricus bisporus and their structures were characterized. The proteoglycan, AB-20-IVa-2 showing the most potent anti-complementary and macrophage activity was composed of glucose, galactose, mannose, xylose, fucose and arabinose in a molar ratio of 3.48:1.83:1.00:0.79:0.74:0.11 and its main component amino acids were phenylalanine (34.72%) and valine (27.84%). The neutral polysaccharides, AB-20-Ia and AB-20-IIa-2a showing lower activity than AB-20-IVa-2, consisted of xylose, glucose, mannose, fucose and arabinose in molar ratios of <0.05:<0.05:2.07:1.00:2.72 and 2.16:1.58:1.00:0.20:0.14, respectively. The molecular weights of AB-20-Ia, AB-20-IIa-2a and AB-20-IVa-2 were 840,000, 750,000 and 650,000 respectively. In the $^1H-\;and\;^{13}C-NMR$ spectra of AB-20-Ia and AB-20-IIa-2a, AB-20-Ia showed only ${\beta}-configuration\;(^1H:\;4.8\;ppm,\;^{13}C:\;107.0\;ppm)$ in the anomerization of the glycosidic linkages, while AB-20-IIa-2a had both ${\alpha}-anomer\;(^1H:\;5.4\;ppm,\;^{13}C:\;102.0\;ppm)\;and\;{\beta}-anomer$. Especially, AB-20-Ia and AB-20-IIa-2a showed acetyl signals $(^1H:\;2.5\;ppm,\;^{13}C:\;21.0\;ppm)$. In the methylation analysis of the three polysaccharides, high proportion of 1,6-linked glucofuranosyl residues were detected in AB-20-Ia, whereas 1,6-linked glucopyranosyl residues and branches linked at position 4 of those mainly contained in AB-20-IIa-2a. AB-20-IVa-2 consisted mainly of 1,2-linked xylofuranosyl residues and 1,6-linked glucopyranosyl residues and branches linked at position 3 of those.

  • CheomSeongDae (瞻星臺) is a stone structure built in Gyeongju, the former Silla Dynasty capital, during the reign of Queen Seondeok (632~647AD). There exist dozens of hypotheses regarding its original purpose. Depending on to whom you ask, the answer could be a celestial observatory, a religious altar, a Buddhist stupa, a monumental tower symbolizing scientific knowledge, and so on. The most common perception of the structure among lay people is a stargazing tower. Historians, however, have suggested that it was intended as "a gateway to the heavens", specifically the Trāyastriṃśa or the second of the six heavens of Kāmadhātu located on the top of Mountain Sumeru. The name "Cheom-seong-dae" could be interpreted in many different ways. 'Cheom (瞻)' could refer to looking up, staring, or admiring, etc.; 'Seong (星)' could mean a star, heaven, night, etc.; and 'heaven' in that context can be a physical or religious reference. 'Dae (臺)' usually refers to a high platform on which people stand or things are placed. Researchers from the science fields often read 'cheom-seong' as 'looking at stars'; while historians read it as 'admiring the Trāyastriṃśa' or 'adoring Śakra'. Śakra is said to be the ruler of Trāyastriṃśa' who governs the Four Heavenly Kings in the Cāturmahārājika heaven, the first of the six heavens of Kāmadhātu. Śakra is the highest authority of the heavenly kings in direct contact with humankind. This paper examined the usages of 'cheom-seong' in Chinese literature dated prior to the publication of 『Samguk Yusa』, a late 13th century Korean Buddhist historical book that contains the oldest record of the structure among all extant historical texts. I found the oldest usage of cheom-seong (瞻星臺) in 『Ekottara Āgama』, a Buddhist script translated into Chinese in the late 4th century, and was surprised to learn that its meaning was 'looking up at the brightness left by Śakra'. I also found that 'cheom-seong' had been incorporated in various religious contexts, such as Hinduism, Confucianism, Buddhist, Christianism, and Taoism. In Buddhism, there was good, bad, and neutral cheom-seong. Good cheom-seong meant to look up to heaven in the practice of asceticism, reading the heavenly god's intentions, and achieving the mindfulness of Buddhism. Bad cheom-seong included all astrological fortunetelling activities performed outside the boundaries of Buddhism. Neutral cheom-seong is secular. It may help people to understand the nature of the physical world, but was considered to have little meaning unless relating to the spiritual world of Buddhism. Cheom-seong had been performed repetitively in the processes of constructing Buddhist temples in China. According to Buddhist scripts, Queen Māyā of Sakya, the birth mother of Gautama Buddha, died seven days after the birth of Buddha, and was reborn in the Trāyastriṃśa heaven. Buddha, before reaching nirvana, ascended from Jetavana to Trāyastriṃśa and spent three months together with his mother. Gautama Buddha then returned to the human world, stepping upon the stairs built by Viśvakarman, the deity of the creative power in Trāyastriṃśa. In later years, King Asoka built a stupa at the site where Buddha descended. Since then, people have believed that the stairway to the heavens appears at a Buddhist stupa. Carefully examining the paragraphic structure of 『Samguk Yusa』's records on Cheomseongdae, plus other historical records, the fact that the alignment between the tomb of Queen Seondeok and Cheomseongdae perfectly matches the sunrise direction at the winter solstice supports this paper's position that Chemseongdae, built in the early years of Queen SeonDeok's reign (632~647AD), was a gateway to the Trāyastriṃśa heaven, just like the stupa at the Daci Temple (慈恩寺) in China built in 654. The meaning of 'Cheom-seong-dae' thus turns out to be 'adoring Trāyastriṃśa stupa', not 'stargazing platform'.

  • This study is about the availability of Chinese internal arbitration institutions by Korean invested companies. Generally, Chinese internal arbitration institutions lack independence from government. However, because parties seeking an arbitration award have ways to get neutrality from internal arbitration institutions that guarantee party autonomy, these Korean companies can use Chinese internal arbitration institutions to resolve disputes in China. Special attention should be given to the following. First, because Korean companies invested in China are legally in the same position as Chinese companies, unless foreign-related factors intervene, when disputes occur with Chinese companies or individuals, the disputes correspond to internal dispute, and when it comes to choosing the arbitration institution, these Korean companies must choose either a Chinese internal arbitration institution or foreign-related arbitration institution. Second, most Chinese internal arbitration institutions still lack independence from government, which can influence the fairness of arbitration in the future. Therefore, Korean companies invested in China should think about alternative ways to get a minimum impartiality in arbitration cases. Third, the parties are allowed to choose arbitration rules freely in Beijing, Xian, Chongqing, Guangzhou, and Hangzhou arbitration commissions. Therefore, in arbitration cases, the parties can get impartiality by choosing arbitrators according to the arbitration rules which they agree on, or by choosing partially modified arbitration rules of those arbitration commissions. Fourth, in order to get an impartial arbitration award from Chinese internal arbitration institutions in China, it is important for Korean lawyers or arbitration experts -- fluent in Chinese -- to be registered in the List of Arbitrators of Chinese internal arbitration institution by way of signing a MOU between the Korean Commercial Arbitration Board, or the Korean Association of Arbitration Studies and arbitration commissions such as those of Beijing, Xian, Chongqing, Guangzhou, and Hangzhou which comparatively do guarantee party autonomy. Fifth, because application of the preservation of property before application of arbitration is not approved in China, in practice, in order to preserve property before application of arbitration, it is best to file another suit in China based on other legal issue (e.g., tort) independent from the contract which an arbitration agreement is applied to. Sixth, in arbitration commissions which allow different agreement regarding arbitration procedures or arbitration rules, it is possible to choose a neutral arbitrator from a third country as a presiding arbitrator via UNCITRAL arbitration rules or ICC arbitration rules. Seventh, in the case of Chinese internal arbitral award, because the court reviews the substantive matters to decide the refusal of compulsory execution, the execution rate could be relatively lower than that of foreign-related cases. Therefore, when Korean companies invested in China use Chinese internal arbitration institution, they should endure low rate of execution. Eighth, considering the operational experiences of public policy on foreign-related arbitration awards so far, in cases of Chinese internal arbitration award, the possibility of cancellation of arbitral award or the possibility to refuse to execute the award due to public policy is thought to be higher than that of foreign arbitral awards. Ninth, even though a treaty on judicial assistance in civil and commercial matters has been signed between Korea and China, and it includes a provision on acknowledgement and enforcement of arbitral award, when trying to resolve disputes through Chinese internal arbitration institution, the treaty would not be a big help to resolve the disputes, because the disputes between Korean companies invested in China and the party in China are not subject to the treaty. Tenth, considering recent tendency of conciliation by the arbitral tribunal in China and the voluntary execution rate of the parties, the system of conciliation by the arbitral tribunal is expected to affect as a positive factor the Korean companies that use Chinese internal arbitration institution. Finally, when using online arbitration, arbitration fees can be reduced, and if the arbitration commissions guaranteeing party autonomy have online arbitration system, the possibility of getting impartial arbitration award through them is higher. Therefore, the use of online arbitration system is recommended.

  • In this study, the good brewing conditions for the 24 $^{\circ}Brix$ freeze-concentrated apple wine were investigated. The four selected Saccharomyces cerevisiae strains MM10, SS89, SS812, and WW108, could ferment quickly when brewed with high sugar levels. During the fermentation, the reducing sugar contents slowly declined while the total acid in all the yeasts increased and the final alcohol content was 12-13%, a typical wine's alcohol content. The viable counts were shown to be 6-6.8 log cfu/ml. During the fermentation, the organic acid content was shown to be within the range of 2.36-3.11%, and the free sugar content, except for the SS89 and WW108 strains, was shown to consist only of sorbitol, although fructose was somewhat detected in the SS89 and WW108 strains. Methanol was not detected, or only a trace of it was detected, and the aldehyde content was 107.68-114.27 ppm. As for the fusel oil contents, a trace of propanol was detected. Isobutanol and butanol were present in 40.16-54.65 and 25.47-27.73 ppm, respectively. The isoamy1 alcohol content was shown to be the highest (108.88-217.26 ppm). The final total phenolic compounds were shown to be 0.1-0.16%. The final Hue values were shown to be 1.3-3.6, and the final intensity was 0.1-0.45. The lightness (L) was within the range of 91.78-98.51, the redness (a) was at a neutral position at red and green, and the yellowness (b) was within the range of 2.38-7.7. In the sensory evaluation, the SS812 strain was found to be the best in terms of color, the SS89 strain in terms of odor, and the WW108 strain in terms of taste. Overall, SS812 was found to be the best apple wine.

  • Objectives : An in vitro biomechanical study of posterior lumbar interbody fusion(PLIF) with threaded cage using two different approaches was performed on eighteen functional spinal units of bovine lumbar spines. The purpose of this study was to compare the segmental stiffnesses among PLIF with one long posterolateral cage, PLIF with one long posterolateral cage and simultaneous facet joint fixation, and PLIF with two posterior cages. Methods : Eighteen bovine lumbar functional spinal units were divided into three groups. All specimens were tested intact and with cage insertion. Group 1(n=12) had a long threaded cage($15{\times}36mm$) inserted posterolaterally and oriented counter anterolaterally on the left side by posterior approach with left unilateral facetectomy. Group 2(n=6) had two regular length cages($15{\times}24mm$) inserted posteriorly with bilateral facetectomy. Six specimens from group 1 were then retested after unilateral facet joint screw fixation in neutral(group 3). Likewise, the other six specimens from group 1 were retested after fixation with a facet joint screw in an extended position(group 4). Nondestructive tests were performed in pure compression, flexion, extension, lateral bending, and torsion. Results : PLIF with a single cage, group 1, had a significantly higher stiffnesses than PLIF with two cages, group 2, in left and right torsion(p<0.05). Group 1 showed higher stiffness values than group 2 in pure compression, flexion, left and right bending but were not significantly different. Group 3 showed a significant increase in stiffness in comparison to group 1 for pure compression, extension, left bending and right torsion(p<0.05). For group 4, the stiffness significantly increased in comparison to group 1 for extension, flexion and right torsion(p<0.05). Although there was no significant difference between groups 3 and 4, group 4 had increased stiffness in extension, flexion, right bending and torsion. Conclusion : Posterior lumbar interbody fusion with a single long threaded cage inserted posterolaterally with unilateral facetectomy enables sufficient decompression while maintaining a majority of the posterior elements. In combination with a facet joint screw fixation, adequate postoperative stability can be achieved. We suggest that posterolateral insertion of a long threaded cage is biomechanically an ideal alternative to PLIF.

  • Korean Shamanism has long been regarded as the peripheral cult or supersition by the majoriy of the society. This fact is a result by the influence of the mass media, especially the motion pictures, which intentionally reflected the negative images of the Shamanism. The documentary films, which stress the objectivity and the reality, rather disclose the neutral position toward the Shamanism. In fact, the directors of the documentary films who have more or less close relationship with the Shamanism have tried to exhibit the mental world and the traditionality of the Shamanism. In this paper, I will explore the value of Shamanism reflected in the documentary films. I focus of two films; directed by the Korean and directed by a foreigner. In this way, I can compare the attitudes of the two directors toward the Korean Shamanism. The director of confessed that he was attracted by the aspect of a musical underlied in the shaman ritual. However, the film does not show the artistic beauty of the shaman music because the director failed to understand the essential aspect of the shaman ritual, that is, the music. In this way, the director failed to show the distinct characteristics of the shamanism to the audience. The director of , a music herself, was focused on the music of the shamanism. The story flows to the adventure to seek a "master" with a long journey to enjoy diverse genres of Korean performing arts. This story resembles the epic shaman song, the Princess Bari. In this way, the audience can easily grasp the beauty of Korean culture. Music is said to be a universal language and, at the same time, a non-universal language which reflects a special trait of a cultural community. The Korean shaman ritual music is a non-universal language that is an accumulation of the Korean culture for a long time. The Korean director fails to exhibit the essential characteristics of the Shamanism since he does not have enough knowledge toward the shaman ritual music in . However, the foreign director, who is a music herself, successively disclose the underlying beauty of Korean shaman ritual music and Korean traditional culture in .
