The origin of Korean mime is traceable to sacred actions of prehistoric age. There are materials about mime of this age in the archeological materials of this age, oral literature/myth, and written literature about this age. There were traces of the most original form of mime in primitive ritual of tribal nation age. The mimes of Samkooksidae/Tree Nation Age of Korea were presented to forms of Kamoobekhee(歌舞百戱)/Sanakbekhee(散樂百戱). We can discover traces of mime of this age in Hosunmoo(胡旋舞), Gwangsumoo(廣袖舞), Kweraehee(傀儡戱), Keeak(伎樂), Kummoo(劍舞) Muaemoo(無㝵舞), and so forth. Especially, Keeak in Beckjae was mask mime of Buddhistic contents. We can recognize that secular theatres were more diversified and strengthened than sacred thaetres in Nambukgooksidae/South-north Nation Age. According to these changes, there were many changes in the mime of this age. We can concretely find traditions of mime of this age in Cheryongkamoo(處容歌舞), Hwangchanmoo(黃倡舞), Taemyun(大面), Wuljen(月顚), Sodok(束毒)', Sanyae (狻猊), and so forth. Mimes of Koreasidae/Korea Age take diverse forms of puppet play, mask play, dance play. Established traditional mimes as Cheryongkamoo(處容歌舞) were widely disseminated in society. And dance plays of mime form as Hunsundo(獻仙桃), Pokurak(抛毬樂), Yunhwadae(蓮花臺)' were imported from Song Nation of China. Mime of Chosundidae/Chosun Age were developed with changes of theatre that were divided into Kyusickjeehee[規式之戲] as Kwangdae(廣大), Ser-in(西人), Joojil(注叱), Rongryung(弄鈴), Kendoo(斤頭) and Sohakjihee[笑謔之戱] as Soochuk(水尺) Sengkwangdae(僧廣大). Styles of theatre in this age were specialized into mudangkuk, Pungmoolkut, Inhyunguk/Puppet play, Talnoree/Mask paly, Pansori, Kungjoong Kamuakguk. According to this changes, mime of this age were specialized into diverse aspects. Korean mime were specialized into Kutnorum-formed mime, Inhyungnorum-formed mime, Jabsaeknorum-formed mime, Talnorum-formed mime, Kungjoongmuyong-formed mime, Pansori-formed mime, and so forth.

There are the farmer's needs to develop early-maturing cultivar adaptable to mid-northern inland plain and alpine area. Furthermore, it is required to develop a rice variety to produce new rice before concentrated marketing dates, even in the years of early Chuseok. 'Joun' is a new extremely early-maturing japonica rice cultivar developed in 2009 from the cross of SR14880-173-3-3-2-2-2/Unbong20 at Cheolwon Substation, National Institute of Crop Science (NICS), Rural Development Administration (RDA). The heading date of 'Joun' is July 23 in mid-northern alpine area, which is 7 days earlier than that of Odaebyeo. It has about 61 cm in culm length with semi-erect plant type. Panicle has a few awns and its exertion is good. The number of spikelets per panicle is smaller than that of Odaebyeo and 1,000 grain-weight of brown rice is 21.2 g which is less than 26.3 g of Odaebyeo, but the complete grain ratio is higher. Milled kernels are translucent with non-glutinous endosperm and palatability of cooked rice is good. It shows strong resistance to cold treatment, lodging, premature heading, wilting and viviparous germination during ripening stage. This cultivar shows resistance to leaf blast disease but susceptible to bacterial blight, virus disease and insect pests. The milled rice yield performance of 'Joun' is about 5.18 MT/ha by ordinary culture in local adaptability test for three years. This cultivar may be highly adaptable to the mid-northern inland plain and alpine area, north-eastern coastal area and middle plain area.

Since USSR successfully launched its satellite "Sputnik"in 1957, many countries including US and USSR began military use of space, and engaged in arms race in space, which is against spirit and ideals of peaceful use of space as common heritage of mankind stipulated in many treaties such as Outer Space Treaty. With worsening Cold War between East and Western Bloc, this military use of space and arms race in space has been intensifying. Regarding the ideals of peaceful use of space, it is interpreted that military use of space is possible unless it does not have the purpose of aggression. The military use of space may have diverse forms such as attacking satellites in space, or attacking from satellites, making use of present and future technologies available which should include the use of nuclear and kinetic/hyper-speed weapons, laser, particle beams, near explosion, disturbance weapons in different directions (i.e., surface to space, space to space, and space to surface). Arms control is being implemented by the efforts of many countries in different formalities including legislature of international treaties under the auspices of UNCOPUOS and prohibition of weapons of mass destruction. Taking outstanding examples aiming at arms control by international community, there are confidence building measures (CBM), strengthening implementation of existing treaties, partial ban of nuclear tests, countryand regional approach, comprehensive approach and measures having legally binding force. While U.S. has surpassed other countries concerned in the area of military useof space, it withdrew from OST in early 2000s, thereby raising concern of international community. It requires concerted efforts of cooperationand implementation by international society to make sure peace of mankind and environmental conservation through arms control in space. Observing de facto possession of nuclear weapons by North Korea following series of nuclear tests and launching satellites, and efforts of launching rockets by South Korea, it is strongly needed for both countries to take part in arms control efforts by international community.

Introduction: The objective of the present study was to investigate the independent effects of major depressive disorder (MDD) and insomnia on somatization, respectively. Methods: A total of 181 participants (73 males and 108 females ; mean age $41.59{\pm}8.92$) without serious medical problem were recruited from a community and a psychiatric clinic in Republic of Korea. Subjects were divided into 4 groups based on the Structured Clinical Interview for DSM-IV axis I disorder (SCID-IV) and sleep questionnaire : 1) normal controls (n=127), 2) primary insomnia (n=11), 3) MDD without insomnia (n=14), and 4) MDD with insomnia (n=29). All participants were requested to complete the somatization subscores of the Symptom Checklist-90-Revised (SCL-90-R). Results: There were significant between-group differences in somatization score (F=25.30, p<0.001). Subjects with both MDD and insomnia showed higher somatization score compared to normal control (p<0.001), subjects with primary insomnia (p=0.01), or MDD subjects without insomnia (p<0.001). Subjects with primary insomnia had higher somatization score than normal controls (p<0.01), while there was no significant difference between MDD subjects without insomnia and normal controls. In multiple regression, presence of insomnia predicted higher somatization score (beta=0.44, p<0.001), while there was only non-significant association between MDD and somatization (beta=0.14, p=0.08). Conclusion: In the current study, insomnia was associated with somatization independently from major depression. Subjects with primary insomnia showed higher somatization. Within MDD patients, presence of insomnia was related to higher somatization. Our finding suggests that insomnia may partly mediate the relationship between depression and somatization.

Wild grape is a traditional medicine plant in north-eastern part of Asia and has been known to have healing properties for various illnesses. This study was to determine the optimum extraction condition and antioxidant activity of ethanol extracts of wild grape (V. coignetiae) seed. Also, organic solvent fractions of hexane, chloroform, ethyl acetate and butanol were obtained from the ethanol extract of wild grape seed at different temperatures. Total ethanol extraction yield of wild grape seed ranged from $4\%\;to\;12\%$ depending on the ethanol concentration, extraction temperature and time condition. The highest extraction yield of $11.9\%$ was obtained at $90\%$ ethanol condition for 12 hour at $70^{\circ}C$. However, the strongest free radical scavenging effect $(RC_{50})$ with $20.93\mu g/mL$ was observed in $70\%$ ethanol extract of wild grape seed extracted for 6 hour at $70^{\circ}C,\;while\;RC_{50}\;with\;40.42$\mu g/mL$ was observed in $90\%$ ethanol extract for 12 hour at $70^{\circ}C$. Antioxidant activity of ethanol extracts of wild grape seed increased as total phenol contents increased. Among each fraction obtained from organic solvents, ethyl acetate fraction was found to have the strongest $RC_{50}\;(8.6\mu g/mL)$ and 636.77 mg GAE/g phenol contents .

This study suggested methodology of Citizen Science as a tool of ecosystem conservation and management to achieve Wetland Protected Area (WPA) Conservation Plan and examined whose applicability in 3 WPAs (Jangrok of Gwangju metropolitan city, Madongho of Goseong in South Gyeongsang Province, and Incheongang estuary of Gochang in North Jeolla Province). It consists of a) figuring out main interests and stakeholder or beneficiaries of WPA and their information demand based on conservation, utilization, and management target in the WPA Conservation Plan, b) conducting research activities to gain outcome to address stakeholder's demand, and c) returning the research outcome to citizen scientists and making diffusion to the society. Based on the suggested method and process, citizen scientists conducted ecosystem monitoring (plants including Invasive Alien Plants, terrestrial insects, traces of mammals, discovering unknown wetland). As a result, citizen scientists contributed to collecting species information of 16 plans, 43 species of terrestrial insects, 5 mammals including Lutra lutra (Endangered Species I) and Prionailurus bengalensis (Endangered Species II). The authors constructed and provided distribution map of Invasive Alien Plants, which included information of location and density which citizen scientists registered, for Environment Agencies and local governments who manage 3 WPAs to aid data-based ecosystem policy, In further studies, not only accumulating research data and outcomes acquired from citizen science to suffice the policy demands but also deliberate reviewing policy applicability and social·economic ripple effect should be processed for the suggested Citizen Science in WPA to be settled down as a tool of ecosystem conservation and management.

DNA barcoding without assessing reliability and validity causes taxonomic errors of species identification, which is responsible for disruptions of their conservation and aquaculture industry. Although DNA barcoding facilitates molecular identification and phylogenetic analysis of species, its availability in clariid catfish lineage remains uncertain. In this study, DNA barcoding was developed and validated for clariid catfish. 2,970 barcode sequences from mitochondrial cytochrome c oxidase I (COI) and cytochrome b (Cytb) genes and D-loop sequences were analyzed for 37 clariid catfish species. The highest intraspecific nearest neighbor distances were 85.47%, 98.03%, and 89.10% for COI, Cytb, and D-loop sequences, respectively. This suggests that the Cytb gene is the most appropriate for identifying clariid catfish and can serve as a standard region for DNA barcoding. A positive barcoding gap between interspecific and intraspecific sequence divergence was observed in the Cytb dataset but not in the COI and D-loop datasets. Intraspecific variation was typically less than 4.4%, whereas interspecific variation was generally more than 66.9%. However, a species complex was detected in walking catfish and significant intraspecific sequence divergence was observed in North African catfish. These findings suggest the need to focus on developing a DNA barcoding system for classifying clariid catfish properly and to validate its efficacy for a wider range of clariid catfish. With an enriched database of multiple sequences from a target species and its genus, species identification can be more accurate and biodiversity assessment of the species can be facilitated.

This study was carried out to assess the variation of saponin contents in 293 Korean native soybean landraces reintroduced from USA to Korea in 2007. Group A saponin content ranged from 149.8 ${\mu}g\;g^{-1}$ to 1279.0 ${\mu}g\;g^{-1}$ with an average of 484.9 ${\mu}g\;g^{-1}$. Group B saponin content ranged from 2160.1 ${\mu}g\;g^{-1}$ to 7868.6 ${\mu}g\;g^{-1}$ with an average of 3670.0 ${\mu}g\;g^{-1}$. Total saponin content including both group A and B contents ranged from 2502.8 to 8764.0 ${\mu}g\;g^{-1}$ with an average of 4154.9 ${\mu}g\;g^{-1}$. Five promising landraces for use as breeding materials that showed higher than any other landraces in group B and total saponin content were IT226841, IT226761, IT226841, IT226828 and IT228534. IT226841 showed the highest saponin content with group B content of 7868.5 ${\mu}g\;g^{-1}$ and total saponin content of 8764.0 ${\mu}g\;g^{-1}$ among landraces. In the relationship among each components, group A saponin content showed a positive correlation with group B saponin content (r=0.3708) and total saponin content (r=0.5119). Group B saponin content showed a very high positive correlation (r=0.9876) with total saponin content. When landraces were compared for the total saponin content based on collected location, landraces from North Korea showed the highest, Gyeonggi-do showed second highest content, followed by Chungcheongbuk-do, Gangwon-do, Gyongsangbuk-do, Chungcheongnam-do, Gyongsangnam-do, Jeollabuk-do and Jeollanam-do. Landraces were also grouped according to seed size and seed coat color. Small seed group was higher than medium and large seed groups that showed no significant difference in total saponin content. Seed coat colors showed no significant difference in total saponin content.
