We have studied vortex dynamics in$ Bi_2$$Sr_2$$CaCu_2$O$_{8}$single crystals of unirradiated and irradiated samples by using 100 $\times$ $100\mu\textrm{m}^2$Hall sensor. Doses equivalent magnetic fields are 20 G, 100 G and 1 kG. In the magnetization measurement, a second magnetization peak (SMP) was observed in unirradiated, 20 G dose and 100 G dose samples in contrast to 1 kG dose sample. In the unirradiated sample, the SMP was observed in the range of 18 K ~ 35 K and the amplitude of the SMP decreased with increasing temperature. With increase of the irradiation dose, temperature region and sharpness of the SMP were reduced. In the magnetic relaxation measurement, we observed that the normalized relaxation rate S decreased with increasing the irradiation dose. Our results suggest that the vortex dynamics is not greatly affected by low-density columnar defects.s.

In this study, a conjoint analysis was conducted to derive a combination of fishing quota management system by fish species preferred by fishermen. In the analysis, detailed levels were set according to each attribute of the system. For analysis, this study conducted a design question survey for conjoint analysis on 303 fishermen engaged in fishing activities in the offshore and coastal sea. The Conjoint analysis was conducted on all fishermen, offshore fishermen and coastal fishermen. In addition, an analysis was conducted on TAC system participants and non-TAC system participants, and the targets were classified for comparison according to the characteristics of fishermen. Fishermen's preference for the system confirmed for six attribute ("catching fish even if there is no fishing quota", "how to allocate fishing quota", "fishing quota management agency", "upper limit of fishing quota," "Possibility of Trading in the Fishing Quota", and "Application of Other Regulations.") and the detailed level of each attribute. As a result of the analysis of the importance of attributes, fishermen thought that "fishing quota management agency (24.1%)" was very important, and "catching fish even if there is no fishing quota (23.9%)" and "how to allocate fishing quotas (22.9%)" were also given some importance.

This essay interpreted and analyzed 3 Bonpuri (shamanic rituals) of Jeju Island from Jungian perspectives. These rituals (Chokong, Euigong, and Samgong Bonpuri) includes myths about gods who have both anthropomorphic and supreme aspects. 3 myths showed significant psychological motifs such as hieros gamos, parental complex, ethics, numinose, creativity, and return to the origin. Compared to other religious worshipping ceremony such as shamanism in North America, sufism, and tantraism, similar psychological motifs are discussed. Understanding and amplifying the psychological symbols and process related these motifs may help analysis to be more meaningful and revivifying the human psyche especially in distress and sadness.

Adoration for nature constitutes one of the primary subjects that literature has tackled since the origin of human history. Nature expressed through a poet's subjective imagination is the internalized and reorganized nature. This study examines the view on nature enacted in Ch'o-Jung's three-verse poems (sijo) in light of the traditional views on nature implicated in the ancient three-verse poems (koshijo), which is in line with the long-established Oriental view on nature. To dignitaris(sadaebu) in the Chosun Dynasty, nature appeared as the idealistic subject for moral culture ($shims{\breve{o}}ngsuyang$), which also becomes the literary space where the purity and justice of the world view of Neo-Confucianism(Sungrihak) is contained in the form of the three-verse poem, the lyrical poetic space where the "I" is united with nature by way of "enjoying of wind and moon"($umpungnongw{\breve{o}}i$) and "living in quiet retiremen"($yuyuchaj{\breve{o}}k$), and the object for the poetical perception of the surrounding world. Ch'o-Jung' s three-verse odes are found in Reed pipe ($Ch'oj{\breve{o}}k$), Sixty Five Pieces of Three-Verse Odes (Samhaengshi-$yukshipopy{\breve{o}}n$), Autumn Fragrance ($Hyangginam{\check{u}}n-ga{\check{u}}l$), and The Words of Zelko va Tree ($N{\check{u}}tinamu{\check{u}}i-mal$). This study analyzes 212 pieces of Ch'o-Jung' s three-verse poems chosen from theses books. In Ch'o-Jung's poems, the traditional view on nature expressed in the ancient three-verse poems is rendered in such a way that metaphysical understanding of nature is indirectly transmitted through the objective correlatives found nature. Nature is no longer the object of straightforward utterance, but transformed, displaced, and removed: that way, nature gets objectified to form a complicated and multi-layered structure. In conclusion, the view on nature manifested in Ch'o-Jung's three-verse poems is based on traditional metaphysics. Second, nature is the object of lyrical nostalgia and adoration. Third, nature is imbued with the fundamental affection for parents. Fourth, nature is associated with organic life. Fifth, the nature in Ch'o-Jung's poems reveals the beauty of stillness endorsed in Lao-tse's and Chung-tze's philosophy. And last, nature is the agent for self-realization and meditation.

This study examined the Korean folklore "Borrowed Fortune from Heaven" from the perspective of Analytical Psychology, considering it a manifestation of the human psyche, and tried to gain a deeper understanding of what happens in our mind. Through the exploration, the researcher was able to re-identify the ongoing psychological process operating in the depths of our mind, pertaining to the emergence of a new dimension of consciousness. Particularly the researcher was able to gain some insights into how the potential psychic elements for the new consciousness are prepared in the unconscious, how they get integrated into the conscious life, and what is essential for the accomplishment of the process. The tale begins with a poor woodcutter who, in order to escape from poverty, starts gathering twice as much firewood. However, the newly acquired amount disappears overnight, so the woodcutter gets perplexed and curious about where it goes and who is taking it. He seeks to find out the truth, which leads him to an unexpected journey to Heaven. There he learns the truth concerning his very tiny amount of fortune, and discovers another big fortune for an unborn person. By pleading with the ruler of Heaven, the woodcutter borrows that grand fortune, on the condition that he must return it to the owner when the time comes. After that, the woodcutter's life undergoes a series of changes, in which he finally becomes a wealthy farmer, but gradually is reminded more and more that the destined time is approaching. In the end, the fortune is completely transferred to the original owner, resulting in a dramatic twist and the creation of a new life circumstances. The overall plot can be understood as a reflection of the psychological process aiming at the evolution of consciousness through renewal. In this context, the woodcutter can be considered a psychic element that undergoes a continuous transformation in preparation for participating in the upcoming new consciousness. In other words, the changes brought about by this figure can be interpreted as a gradual and increasingly detailed foreshadowing of what the forthcoming new consciousness would be like. Interestingly, as the destined time approaches, the protagonist's anguish in conflict reaches its climax, despite his good performance in his role until then. This effectively portrays the difficulty of achieving a new dimension of consciousness, which requires moving past the last step. All the events in the story ultimately converge at this point. After all, the resolution occurs when the protagonist lets go of everything he has and follows the will of Heaven. This implies what is essential for the renewal of consciousness. Only by completely complying with the entire mind, the potential constituents of the new consciousness that should play important roles in a renewal and evolution of consciousness through experiencing, can participate in the ultimate outcome. As long as they remain trapped in any intermediate stage, the totality of the psyche would develop another detour aiming at the final destination, which means the beginning of another period of suffering carrying a purposeful meaning. The tale suggests that this truth will be applied everywhere that renewal of consciousness is directed, whether for an individual or a society.

This text attempts two types of critical analysis. First is to explore Luxun's critical research attitude toward classical Chinese texts, studying how Luxun critically examines 'liyue (ceremony- music)'. With the way the 'madman' in 《A Madman's Diary》 handles China's old text as a hint, the attitude with which Luxun critically examines the editing and passing down of classical Chinese philology was studied. Luxun pays attention to the situation in which when classical literature is passed down and transmitted throughout history, the context of events are concealed and text is blockaded while text is edited and restructured. Also, Luxun critically examines how the ancient culture of 'liyue' operates on the constitution of Chinese culture, society, and politics, in addition to the process of passing down of texts, as well as how it has effect even in the present day. Classics are closely intertwined not only with issues of the past but with the conventions, moral emotions, and government of today. Second, based on Luxun's examination of 'liyue', the <sheng-wu-ai-le-lun> of the 《Jikangji》 which Luxun sympathized with all his life is criticized. This text, stating that 'There is no sadness or happiness in sound', deeply ponders upon the issue of 'liyue' essential to the logic of Chinese cultural composition, and deviates from the Confucian thoughts centered around social integrity and inspiration. Further, it stresses the autonomy of affective subject, and the process of deliberation by an entity toward harmony and commonness. By the work of examining Jikang through Luxun and Luxun through Jikang, the uncompleted work of classical criticism by Luxun is restructured, and the possibility of classical Chinese texts to relate to today's life is examined.

Using an electrolyte additive, we examined, for the first time, a novel self-ordering regime of 160~200 V in high-field anodization which had been used for a fast fabrication of self-ordered anodic alumina nanotemplate. FE-SEM analyses conducted after the high-field anodization, pulse detachment and chemical widening of pores showed the relationship of 2.2 nm/V in this voltage range, which was identical to the previously reported one in the literature. The growth rate of the alumina film was about 60 um/hr, which was 30 times faster than that of phosphoric acid mild anodization. This study provides a new process for the fast fabrication of nanotemplates with interpore distances larger than 300 nm.
