  • Objective: The study was designed to determine the cytotoxic effect of gallic acid (GA), obtained by the hydrolysis of tannins, on mice TM4 Sertoli cells apoptosis. Methods: In the present study, non-tumorigenic mice TM4 Sertoli cells were treated with different concentrations of GA for 24 h. After treatment, cell viability was evaluated using WST-1, mitochondrial dysfunction, cells apoptosis and necrosis was detected using JC-1, Hoechst 33342 and propidium iodide staining. The expression levels of Cyclin B1, proliferating cell nuclear antigen (PCNA), Bcl-2-associated X protein (BAX), and Caspase-3 were also detected by quantitative real-time polymerase chain reaction and Western-blotting. Results: The results showed that 20 to $400{\mu}M$ GA inhibited viability of TM4 Sertoli cells in a dose-dependent manner. Treatment with $400{\mu}M$ GA significantly inhibited PCNA and Cyclin B1 expression, however up-regulated BAX and Caspase-3 expression, caused mitochondrial membrane depolarization, activated Caspase-3, and induced DNA damage, thus, markedly increased the numbers of dead cells. Conclusion: Our findings showed that GA could disrupt mitochondrial function and caused TM4 cells to undergo apoptosis and necrosis.

  • As the first of Philip Roth's recent series of novels that delve into American Cold War history deeply entwined with the post-war Jewish American experience, American Pastoral traces the tragic fall of a third-generation Jewish American named Seymour "Swede" Levov, whose dream of complete assimilation to the post-ethnic American paradise is irrecoverably disrupted when his young daughter blows up the local post office to protest against the Vietnam War. This essay proposes to examine Swede Levov's interrupted pursuit of the American dream by locating it within specific Cold War contexts and national imaginaries propagated particularly during the years from John F. Kennedy to Lyndon B. Johnson. In so doing, I will argue that Roth presents a paradoxical vision of Jewish American identity that could be acquired by performing perpetual self-effacement and submergence into the non-place of anonymity and doubleness, a mythic location of the post-ethnic Cold War American family. Levov's life becomes true part of the mythic narrative of American history when he realizes that his life, just like the nation's history, is a series of temporalities radically discontinued without any manageable detour ot divine bypass to cross over. Rather than indicating Roth's retraction from the postmodern understanding of subjectivity, the novel's historical realism, I will argue, serves to illuminate the postmodern conditions of American Cold War history and ethnic identity.

  • As a means to activate eco pastoral system in alpine grassland, the government can consider public pastures, which are currently unused, to scale them up into public ranches. Depending on ownership and operation, four management models proposed as follows: 1) Government-Owned and Operated with Balanced Profit and Loss 2) Government-Owned and Operated with Revenue Generation 3) Government-Owned but Privately Operated by Outsourced to Professional Manager 4) Full Privatization (Ownership and Operation by Private Individuals). The study outlined above proposes four management models for the activation of eco pastoral system in alpine grassland. It also suggests methods for the selection and performance evaluation of manager to establish a profitable structure. Additionally, the research provides management methods for the conservation of grazing ecology in pastoral ecosystems. Particularly, the adaptation of tools commonly used in South Korean business sector for the selection and performance evaluation of manager within the system of the proposed management models. This aspect is deemed valuable as it aligns these tools with the specific characteristics of eco pastoral system in alpine grassland, contributing not only to the effective implementation of the models but also to the enhancement of the revenue structure.

  • Beef and dairy cattle are the primary ruminant livestock in Korea, but there is a serious shortage of both fresh and dry forages. Small areas of forage crops or pastures, unfavorable soil and climatic conditions, high costs for pasture production, low establishment and management technologies, etc. are the main factors limiting roughage production in Korea. To meet the roughage demand of cattle several suggestions are presented. About 845,000 ha of hilly area could be developed for pastureland. Almost the same area of paddy field, and more than 200,000 ha of reclaimed land could be used for pasture production. If all the potential area is developed for pastureland, the area could be extended to 10 times more than is presently used for pasture crops and pastureland. Productivity would be increased by developing new technologies of establishment and management. Silvo-pastoral systems should be introduced to Korea.

  • Seamus Heaney, a famous Irish poet after Yeats, has written some pastoral lyrics from his experiences of farm life and childhood memories. These poems, in spite of his simple overt praise of a rustic farm life, have layers of meaning with their vast allusiveness and implications. He is an extremely literary writer dealing with history from the Celtic myth and a long English literary history. Though his style reminds that of a Victorian poet through his allusions of nature, he is a modern poet of innovative skills and senses. The explication of his representative sonnet sequence, the "Glanmore Sonnets" will reveal exquisite, complicated poetics of a modern poet. The poems are basically love poems, and the love is directed to his beloved wife, his lifetime companion. The poems relate the cultivation of a land to the poet's excavating language from the classics and to the images of love making. Through a careful reading of the sonnets this article will broaden our knowledge on how a modern love lyric of layered meanings can retain the past tradition in its complicated poetics.

  • This study is to be used for research material for pastoral counseling, by analyzing grounded-theoretically how substance abusers' awareness of self and experience of relations affects problems in abusing drugs. The subject of this study was chosen as 9 prisoners who were able to participate in group counseling, among those who were in prison for substance abuse and had more than 6 months of penal servitude left. In addition, in order to indicate counseling research methods through this study, 12 group counselings were carried out during October 24th. 2002 and February 14th. 2003 and verbatim were written out to be used as original material. After the research material was analyzed, they could be categorized into 60 concepts on the whole from 'conflict' and 'constraining thinking' to 'rationalization' and 'avoidance'. When these concepts were organized into groups of similarity, there were all together 20 categories. From this study, it can be found that substance abusers had "problems about self" and "problems about relations". The factor which affected their use of drugs was the area of relations, where as henceforth their use of drugs, the situation in which they could not escape from the use of substances was affected by problems within the area of self. When facing such problems as substance abuse, the pastoral counselor must create a holding environment through counseling, and perform good enough mothering by being insightful and providing active support on the problem. They must also help one's growth into "an empathizing self", "an accepting self", "a trusting self", "a hopeful self", who can empathize, accept, trust and hope, through experience in separation from the problem, conversion, meta-communication, self-rumination, relations and inspiration of hope. Likewise, the church must be able to act as a "place of growth and skill" which aids in the forming of relations and helps to be aware of self through experience in, and understanding of, relations.
