지금은 이미 지하수가 말라버리고 건조한 동굴이 되었지만 프린스 맘모스 동굴과 같이 큰 포화수대 기원의 터널이나 지하천이 사행하면서 거의 수평으로 발달한 장대한 동굴계는 미국의 대동굴 지대의 전형이라고 할 수 있다. 이 켄터키를 중심으로 북쪽은 펜실베니아, 남쪽은 알라바마까지의 애팔레치아 지방까지 펼쳐진다. 대조적으로 북조지아의 에리존즈동굴은 이 지방의 동굴과 달리 일직선으로 뻗어져 있다. 10이상의 길이로, 양단은 거대한 수직동굴로 되어 있으며 피지온산의 밑을 관통하고 있다. 입구의 수직동굴은 환타스틱 피트, 인크레져블 피트라 불리우며 양쪽모두 150M의 깊이이다. 미국동부의 동굴은 이차생성물은 일반적으로 그렇게 발달되어 있지 않은 것이 하나의 특징이다. 그러나 예외도 있는데 버지니아의 루뤠이 동굴에는 멋진 생성물을 볼 수 있고 관광동굴화 되어 있다.(중략)

인류의 종교사에서 커다란 사건 가운데 하나를 꼽으라면 아마 조로아스터교의 출현을 들 수 있을 것이다. 고대 아시아에서 배화교라고도 알려진 이 종교는 종교사 만큼이나 세계사의 흐름을 바꿔 놓는 데도 큰 역할을 했다. 우선 조로아스터교의 등장은 진정한 세계 제국이 등장할 수 있는 토대가 되었다. 그 이전의 모든 종교는 민족 종교의 성격이 강했다. 그래서 어느 민족이 패권을 잡게 되면 피지배 민족의 신은 철저하게 배척당하거나 파괴되었다. 성경을 접해본 사람이라면 구약의 이스라엘 민족이 정복한 민족과 그들의 신을 얼마나 철저하게 파괴하는지를 알 수 있다. 그러나 조로아스터교의 경우는 다른 종교들과는 조금 달랐다.

The differentiation of the sebaceous gland is remarkably species-specific and sebocytes may play crucial parts in the pathophysiologic processes and disorders of pilosebaceous unit SZ95 cell is an immortalized human sebaceous gland cell line that shows characteristics of normal human sebocytes, In this study, we investigated the effect of testosterone and the anti-androgenic effect of 13-cis-retinoic acid (13-cis-RA) on lipid synthesis in SZ95 cells. Cytoplasmic lipid droplets were shown by Oil-red staining. The majority of the SZ95 cells positively labeled with Oil-red dye, while HaCaT cells negatively labeled with Oil red dye. Total lipid level of SZ96 cells is higher 4 times than that of HaCat cells. Testosterone markedly increased 2 times lipid synthesis of SZ95 cells in compared with control. 13-cis-RA significantly inhibited lipid synthesis and cell proliferation in SZ95 cells. Combined treatment with testosterone and 13-cis-RA resulted in a lower total lipid levels than that with androgen alone. In conclusion, SZ95 cells well resembled the morphologic and functional characteritics of normal human sebocytes. This in vitro model could provide a valuable tool for the study of sebocytes with a key role in pathophysiology and differentiation of sebaceous glands.

The purpose of this paper is to explore the hegemonic masculinity in Disney animated feature films in terms of Antonio Gramsci's hegemony and R. W. Connell's hegemonic masculinity. According to Gramsci, hegemony refers to the predominance of a dominant group over other groups. By the same token, Connell uses the term hegemony as the configuration of gender practice which embodies the domination of men and the subordination of women. He describes four masculinities to explore male hierarchy in male groups: hegemonic masculinity, subordinated masculinity, complicit masculinity, and marginalized masculinity. Through Connell's terms, this study investigates masculinities in Disney films, especially Beauty and the Beast (1991) in relation to hegemonic masculinity. As a result, Disney describes repeatedly hegemonic masculinity as hard body defined by Susan Jeffords and supports tacitly the domination of a specific male group.

This article examines how India's major colonial cities-Madras, Calcutta, Bombay (today, Chennai, Kolkata, Mumbai) and New Delhi- are described in India's history textbooks and analyzed them from the perspective of Indians. It is explained the major colonial cities as the process of making the cities and their political, social, economic and cultural changes, the separation between British and Indian, urban planning, colonial architectures built by British colonial power in Indian history textbooks. The viewpoint of its descriptions is featured by the coexistence of 'deprivation, exclusion, discrimination, resistance, challenge' and 'grant of opportunity, acceptation, absorption'. That is, this characteristic maintains a mutual confrontational and inseparable relation. And in a multi-layer, it enables to consider the inherent characteristics of a colonial city reflecting the British ruling ideology and the society within which the rulers and proprietors are forming without simplifying the cultural characteristics. It is clear that there was a resistance against the unreasonable discrimination and exclusion that had been suffered by the British colonial government as well.

Recently, many supports about the education linked with industrial field have been provided in technical specialized high schools. In order to keep pace with the global trend to emphasize software education and to move away from traditional grammar-based programming learning, various physical computing tools have been used in the education fields. For this study, we conducted a programming class using Raspberry Pi for technical high school students. In the class, students were instructed to produce actual results based on the knowledge they had learned. Project-based learning was used to help students create products and thus they performed tasks while discussing and collaborating on a team-by-team basis. In particular, self-regulation learning strategies were considered to provide effective project-based instruction. After the class, we interviewed the students' satisfaction with it. The results showed that the students' satisfaction was high, and the fellow teachers also had a lot of possibilities and expectations about the programming instruction and project-based learning using Raspberry Pi.

Efficiency study of chamomile and Thyme essential oil about the basal layer & sebaceous gland in dry-skin induced by surfactant is as following : 1. Formal observation of outer skin layer and basal layer There was refreshing effects about Surfactant induction skin inflammation in Chamomile, Thyme essential oil processing group but effect in surface layer appeared by higher thing in Chamomile essential oil and it could know that thing which do not use Thyme essential oil in case Thyme essential oil is ultraviolet rays allergy at skin care because Melanocyte appear on the surface is bigger than Chamomile essential oil that it was usefully reaction in basal layer. 2. Formal observation result of sebaceous glands. There are few damages in all group but there is recuperative through excessive water damage by excessive a sebaceous gland made of mulberry bark secretion because Thyme essential oil application group cause chapped skin phenomenon after surface-active agent processing but is seen that difference does not exist greatly and Thyme essential oil that general skin is strong in permeation is effective, but Surfactant induction skin inflammation estimates that Chamomile essential oil is effective. Therefore, it was considered that use of Chamomile essential oil is effectiveness than Thyme essential oil by essential oil used for recovery after damage of inflammation etc..
