  • This study applied the theory of Landscape Ecology to representative resources of Jeju Olle-gil, which is a representative subject of walking tourism, to identify ecological characteristics and to establish a technique for landscape ecological analysis of Olle-gil resources. Jeju Olle Trail type based on the biotope type, major land use, vegetation status around Olle Trail and roads were divided into 12 types. Based on the type of ecological tourism resource classification, the Jeju Olle-gil walking tourism resource classification was divided into seven types of natural resources and seven types of humanities resources, and each resource was characterized by Geotope, Biotope, and Anthropopope, just like the landscape ecology system. Geotope resources are strong in landscape characteristics such as coast and beach, rocks, bedrocks, waterfalls, geology and Jusangjeolli Cliff, Oreum and craters, water resources, and landscape viewpoints. The Biotope resources showed strong ecological characteristics due to large tree and protected tree, Gotjawal, forest road and vegetation communities, biological habitat, vegetation landscape view point. Antropotope include Culture of Jeju Haenyeo and traditional culture, potting and lighthouses, experience facilities, temples and churches, military and beacon facilities, other historical and cultural facilities, and cultural landscape views. Jeju Olle Trail The representative resources for each type of Jeju Olle Trail are coastal, Oreum, Gotjawal, field and Stonewall Fencing farming land, Jeju Village and Stone wall of Jeju. In order to learn about the components and various functions of the resources representing the Olle Trail's ecological culture, the landscape ecological technique was interpreted. Looking at the ecological and cultural characteristics of coastal, the coast includes black basalt rocks, coastal vegetation, coastal grasslands, coastal rock vegetation, winter migratory birds and Jeju haenyeo. Oreum is a unique volcanic topography, which includes circular and oval mountain bodies, oreum vegetation, crater wetlands, the origin and legend of the name of Oreum, the legend of the name of Oreum, the culture of grazing horses, the use of military purposes, the object of folk belief, and the view from the summit. Gotjawal features rocky bumps, unique microclimate formation, Gotjawal vegetation, geographical names, the culture of charcoal being baked in the past, and bizarre shapes of trees and vines. Field walls include the structure and shape of field walls, field cultivation crops, field wall habitats, Jeju agricultural culture, and field walls. The village includes a stone wall and roof structure built from basalt, a pavilion at the entrance of the village, a yard and garden inside the house, a view of the lives of local people, and an alleyway view. These resources have slowly changed with the long lives of humans, and are now unique to Jeju Island. By providing contents specialized for each type of Olle Trail, tourists who walk on Olle will be able to experience the Olle Trail in depth as they learn the story of the resources, and will be able to increase the sustainable use and satisfaction of Jeju Olle Trail users.

  • Purpose : To investigate a disposal method of disposing contact lenses and the recognition of environmental pollution by micro plastics which may be caused by the wrong disposal method of domestic contact lens wearers. Methods : Two hundred sixty one adults(124 males, 137 females, mean age $21.48{\pm}3.14years$) were participated in this study. They were given the questionnaire survey on contact lenses purchasing place, type of contact lenses, duration of wearing contact lenses, the disposal method of disposing contact lenses and the recognition of the occurrence of environmental pollution. Results : It appeared that eyeglass shop(50.0%) and contact lens shop(48.3%) were the main purchasing places, and the most common type of contact lenses were disposable lenses(38.5%) and daily wearing lenses(52.5%). On the duration of wearing contact lenses they answered more than 5 years(29.3%), less than 1 year (26.0%), less than 1 year to less than 3 years (26.0%), and on wearing a contact lens during a week they did 1-2 days (32.0%), 1 week (28.0%), 5-6 days (22.4%) and 3-4 days (17.6%). It was shown "no(78.3%)" and "yes(21.7%)" to the questionnaire of whether they received information or education about a disposal method at the place where the contact lens was purchased, and "no(87.5%)" and "yes(12.5%)" to the questionnaire of whether they received information or education from schools, public institutions or public media such as the internet. As for the disposal methods, landfill waste(45.6%), recycled garbage(29.6%), and drainage(16.8%) from the sink or toilet responded in order. Although men were more educated and informed about disposal than women (t=3.63189, p<0.00001), women were more aware of environmental pollution(t=2.44269, p=0.01605). Conclusion : In order to reduce the environmental pollution issue caused by the contact lens which does not decompose at the sewage treatment facility and become micro plastics, it is urgent to provide information about correct disposal methods after using contact lenses and to educate contact lens wearers.

  • Purpose : We investigated the change of spherical and comma aberrations after wearing aspheric soft contact lens (ASCL) in young myopes. Methods : Fifty young myopes ($23.15{\pm}1.70years$, spherical equivalent: $-2.90{\pm}1.75D$) were recruited and refractive errors were corrected using ASCL (Biotrue, Bausch+Lomb, USA). High order aberrations were measured in the 4 mm pupil size using the wavefront analyze and pupil sizes were measured with a pupillometer at the modes of scotopic condition (light off) at 3.5 m in the 100 lx illuminance condition. Results : Spherical aberrations and coma aberration of the 20s myopes were $0.026{\pm}0.031{\mu}m$ and $0.078{\pm}0.039{\mu}m$ respectively, and $0.019{\pm}0.026{\mu}m$ and $0.082{\pm}0.038{\mu}m$ after ASCL wear that spherical aberration was decreased and coma aberration was increased. However, spherical aberration was decreased in the 68% of the subject have positive spherical aberration, and increased in the 11% of the subject have negative spherical aberration. Coma aberration was increased in the 53% of the subject, did not change in the 19% of the subjects, and decreased in the 28% of the subject. Spherical aberration was not different with the refractive errors in low and moderate myopies, however, coma aberrations was higher in the higher myopes. Conclusion : In a scotopic condition without accommodation stimuli, spherical aberration is decreased after wearing ASCL, however in the subject have negative spherical aberration spherical aberration could be increased, and which is thought to be the influence of contact lens design and pupil size.

  • Traditionally, the origin of the Han River has been thought as Utongsu(于筒水) and Geumgangyeon(金剛淵). As both of these places are located in Odaesan(五臺山) the $Ma{\tilde{n}}ju{\acute{s}}ri$(文殊) Holy Place, we can well assume the possibility of Buddhist influence on them. In the Buddhist understanding on the origin of the Han River, what we should first notice are 'the recognition on the water of Buddhism' and 'the recognition on the river in Indian culture.' With the reviews, we may come to see by what standpoint these could become existed, if there were Buddhist influences on the recognition of Han River's origin. Based on these Buddhist and Indo-cultural view points, the author tries to make more dearly the definition of Utongsu and Geumgangyeon that are recognized as the origin of the Han River. Through it, we can check the relation of Buddhism and Indian culture in their influence on the concepts of Utongsu and Geumgangyeon. In Indian culture, what is noticed in relation with the origin of the river is Anavatapta, in which the sacredness of the water named the 8 virtuous waters is recorded. It is the materialistic sacredness which can be compared with the sacred feature of Utongsu that "its color and taste are far greater than other waters, and so is its weight. ${\cdots}$ Its color and taste do not change even after it flows into the Han River." Furthermore, both of Anavatapta and Utongsu have the same symbolism of dragon that the highest dragon king and a divine dragon were told to live in respective lakes. This similar structure found in the recognition of two rivers' origin may become an evidence of Buddhist influence on the recognition of the Han River's origin. The recognition of the Han River's origin is based on the traditional culture. Therefore, it may be natural that there is the Buddhist culture in it. At the same time, some viewpoints of Chinese culture can be found in it. So, the traditional recognition on the Han River's origin comprises diversity and complexity of Indian and Chinese cultures together.

The Body of Male Domination and the Problem of the Phallic Ideology: The Strategy of the Deconstruction of Penis-Narcissism and the Penis-Cartel (남성지배의 몸과 남근 이데올로기의 문제: 페니스 나르시시즘과 페니스 카르텔의 해체전략)

  • This article aims to deconstruct the mechanism of male domination that constantly reproduces the hegemonic class of men. In order to overcome misogyny, we should no longer deny the ontological dimension of the reality of women's oppressions and the pre-eminence of the material condition of women's existence. In addition, the possibility of the category of women as a modality of resistance should be taken into consideration. First, I will highlight the correlation between penis and phallus according to which the phallus refers to the penis which is malleable and fragile and which disappears without being castrated by the external factor. From here we could deduce the fragility and imperfection, the non-absoluteness of the phallic order. Secondly, I will analyze the mechanism of penis-narcissism, which is the modality of the constitution of the individual identity of man. The penis is not only a physiological organ, but a site of self-estimation and the validity of the succession of power and authority of the father's law. With this penis-narcissism, man is constituted as a hegemonic body that can let itself go without worrying about the reactions of others. Thirdly, I will focus on the mechanism of the penis-cartel which is the modality of the formation of the collective identity. The penis-cartel is reinforced by the mutual affirmation of the superiority of men among themselves, but also by the permission and the tacit agreement of their absurdity and lack of rationality and corruption. Because the privilege of men is not monopolized by a small part of the elite, but is consciously and unconsciously shared by all men who are part of the hegemonic and collective category. In order to deconstruct the penis-narcissism and the penis-cartel, it is necessary to demonstrate that the penis is not a self-sufficient body, nor a closed and impermeable body, but that it is a porous body where the organ serves both ejaculation and urinary ejection. The penis is a porous body that is at once the site of sublimity and degradation, purity and impurity. In addition, the penis is no longer an all-powerful and aggressive organ, but it is a malleable and fluid flesh that constantly changes its shape. Linked to a phallus-organ that is the notion of Jacques-Alain Miller, it is a site of deficiency and vulnerability that is not the axis of the penis-cartel. It is through the notion of the double porosity of the penis and the phenomenology of the flesh of the penis, I try to provide the modality of undoing the reproductive mechanism of predatory masculinity. Because this would be an effective strategy to overcome misogyny.

  • To understand the morphological differentiation of the 26 accessions of Foxtail Millet collected in Korea (15 accessions), China (7 accessions) and Pakistan (4 accessions), we analyzed 9 morphological characteristics such as plant height, panicle length, leaf number, tiller number, heading time, seed weight and panicle color etc. Most accessions of foxtail millet collected in Korea showed late heading time, tall plant height and long conical panicles. While foxtail millet accessions of Pakistan showed early heading time, short plant height and short conical panicles. In case of Chinese accessions, some accessions of them showed similar characteristics with Korean accessions, and the other showed similar characteristics to Pakistan accessions. In ANOVA analysis, most of quantitative characteristics such as plant height, leaf number, internode number and heading time showed significant differences among foxtail millet accessions collected from Korea, China and Pakistan. Principal component analyses clearly discriminate foxtail millet accessions of Korea from those of China and Pakistan. In PCA analysis, most of quantitative characters such as panicle length, leaf number and internode number greatly contributed in positive direction, whereas several quantitative characters such as tiller number, seed weight and panicle color contributed in negative direction on the first axis. Thus, these morphological characteristics could be used to classify the foxtail millet accessions collected in Korea, China and Pakistan. The present results could expand our understanding of the morphological variation in foxtail millet accessions from Korea, China and Pakistan, and also could be useful for foxtail millet germplasm preservation.

  • This study was conducted to obtain basic information on mainstem, branch and leaf characteristics related to canopy for development of high yielding cultivar using 70 Korean soybean cultivars developed from 1913 to 2000. Variations of canopy width, branch length, and canopy width/length ratio were higher compared to other characteristics among 12 mainstem and branch characters. Variations of petiole angle, leaflet width/length ratio and compound leaf dry weight were higher than other characteristics among eight leaf characters related to plant canopy. Three classifications of soybean cultivars were used based on usage: I)soy sauce and tofu, II)bean sprout, and III)cooking with rice. Canopy width/length ratio was higher in group III, cooking with rice than group I, soy sauce and tofu, and group II, bean sprout, and there was no difference between the two, group I and group II. The total branch length/main stem height ratio was higher in group II, bean sprout and group III, cooking with rice than group I, soy sauce and tofu. Mainstem and branch characteristics related to plant canopy were classified into four groups by ratio of canopy width/length and total branch length/main stem length, respectively. Soybean cultivars with narrow canopy and high dependence of mainstem were Danweonkong, Keumkangkong, Shelby, and Shinpaldalkong. Soybean cultivars with broad canopy and high dependence of mainstem were Kanglim, Keumkangdaelip, and Jinyulkong, and a cultivar with broad canopy and high dependence of branch were Geomjeongkong 2. Leaflet length/width ratio was lowest in cooking with rice and there was no difference between soy sauce and tofu and bean sprout. Compound leaf area was largest in cooking with rice and smallest in bean sprout. Leaf petiole length was short in bean sprout and there was no difference between soy sauce and tofu and bean sprout. Leaf petiole angle was highest in cooking with rice and lowest in bean sprout. Leaf type was classified into four groups based on leaflet width/length ratio and compound leaf area, respectivly. Buseok and Taekwangkong had an oval leaflet and largest area of compound leaf. Eunhakong and Sohokong had extreme narrow leaflet and smallest area of compound leaf. Leaf petiole type was classified into three and four groups based on leaf petiole length and angle, respectively. A soybean cultivar with the shortest petiole length and smallest petiole angle was Eunhakong and cultivars with short petiole length and large petiole angle were Alchankong, Muhankong, and Pureunkong. A soybean cultivar with long petiole length and small petiole angle was Sinpaldalkong 2. Among a total of 70 Korean soybean cultivars, Eunhakong had an extreme narrow type in leaf, smallest compound leaf area, shortest petiole length, and smallest petiole angle of compound leaf.

  • First-order cybernetics during the 1940s and 1950s aimed for control of an observed system, while second-order cybernetics during the mid-1970s aspired to address the mechanism of an observing system. The former pursues an objective, subjectless, approach to a system, whereas the latter prefers a subjective, personal approach to a system. Second-order observation must be noted since a human observer is a living system that has its unique cognition. Maturana and Varela place the autopoiesis of this biological system at the core of second-order cybernetics. They contend that an autpoietic system maintains, transforms and produces itself. Technoscientific recreation of biological autopoiesis opens up to a new step in cybernetics: what I describe as third-order cybernetics. The formation of technoscientific autopoiesis overlaps with the Fourth Industrial Revolution or what Erik Brynjolfsson and Andrew McAfee call the Second Machine Age. It leads to a radical shift from human centrism to posthumanity whereby humanity is mechanized, and machinery is biologized. In two versions of the novel Demon Seed, American novelist Dean Koontz explores the significance of technoscientific autopoiesis. The 1973 version dramatizes two kinds of observers: the technophobic human observer and the technology-friendly machine observer Proteus. As the story concludes, the former dominates the latter with the result that an anthropocentric position still works. The 1997 version, however, reveals the victory of the techno-friendly narrator Proteus over the anthropocentric narrator. Losing his narrational position, the technophobic human narrator of the story disappears. In the 1997 version, Proteus becomes the subject of desire in luring divorcee Susan. He longs to flaunt his male egomaniac. His achievement of male identity is a sign of technological autopoiesis characteristic of third-order cybernetics. To display self-producing capabilities integral to the autonomy of machinery, Koontz's novel demonstrates that Proteus manipulates Susan's egg to produce a human-machine mixture. Koontz's demon child, problematically enough, implicates the future of eugenics in an era of technological autopoiesis. Proteus creates a crossbreed of humanity and machinery to engineer a perfect body and mind. He fixes incurable or intractable diseases through genetic modifications. Proteus transfers a vast amount of digital information to his offspring's brain, which enables the demon child to achieve state-of-the-art intelligence. His technological editing of human genes and consciousness leads to digital standardization through unanimous spread of the best qualities of humanity. He gathers distinguished human genes and mental status much like collecting luxury brands. Accordingly, Proteus's child-making project ultimately moves towards technologically-controlled eugenics. Pointedly, it disturbs the classical ideal of liberal humanism celebrating a human being as the master of his or her nature.

  • Genetic diversity and relationships within and among Korean, Japanese and Chinese Jilin provincial wild soybeans based on SSR markers were evaluated to enlarge genetic variation in soybean breeding in the future. A total of 184 wild soybeans including 67 Korean, 71 Japanese and 46 Chinese Jilin provincial wild soybeans were analyzed to evaluate genetic diversity and relationships based on 23 SSR markers. Korean and Japanese wild soybeans were obtained from National Agrobiodiversity Center, Korea, and Biological Resource Center in Lotus and Glycine, Frontier Science Research Center, University of Miyazaki, Japan, respectively. Chinese wild soybeans were collected from Jilin province, China. Twenty three SSR markers generated a total of 964 alleles with an average of 41.9 alleles per marker. Number of alleles ranged from 23 (Satt635) to 56 (Satt157). Genetic diversity (PIC value) of 184 wild soybeans ranged from 0.880 to 0.968 with an average of 0.945. Number of alleles for Korean, Japanese and Chinese Jilin provincial wild soybeans was 513 with an average of 22.3, 511 with an average of 22.2, and 312 with an average of 13.6 per marker, respectively. PIC value for Korean, Japanese and Chinese Jilin provincial wild soybeans was similar with an average of 0.905, 0.897, and 0.850, respectively. Cluster analysis based on genetic distances estimated by SSR markers classified wild soybeans into 3 clusters. Cluster I included only Chinese Jilin provincial wild soybeans. Cluster II included most of Japanese wild soybeans including 5 Korean wild soybeans. Cluster III included most of Korean wild soybeans including 6 Japanese and 1 Chinese Jilin provincial wild soybeans. Cluster I was not subclassified, but cluster II and III were subclassified into various groups. Genetic distance evaluated by SSR markers between Korean and Japanese wild soybeans was closer than that of between Korean and Chinese Jilin provincial, and between Japanese and Chinese Jilin provincial wild soybeans.

  • This study was undertaken to investigate the genetic diversity and to develop a technique for cultivar discrimination using SSR markers in rice. Sixty-seven recently distributed rice cultivars in Korea from 1998 to 2005 were evaluated by 20 SSR markers. A total of 149 alleles were produced ranging from 4 to 14 alleles with an average of 7.5 alleles per locus. The molecular weight of alleles per locus varied from 4 bp (RM253) to 51 bp (RM335), and PIC values ranged from 0.45 (RM202) to 0.87 (RM204) with an average of 0.67. Of them, seven markers, RM204, RM257, RM21, RM224, RM249, RM253, and RM264, were selected as key markers for differentiating rice varieties. The seven markers produced a total of 67 alleles with an average of 9.6 alleles per marker. PIC values ranged from 0.48 (RM253) to 0.87 (RM204) with an average of 0.72. The 63 cultivars (94%) out of 67 cultivars could be individually identified by the genotype using the seven SSR markers, which will be applicable to discriminating rice cultivars.
