The purpose of this study is to collect and analyze costumes presented in international dance sports competitions, and summarize the features of Latin American dance costumes' design. As for research methods, standards of Latin American dance costume design were analyzed via a literature review on dance sports. The scope of the study extended for six years from 2010 to 2015 to include the, top three UK Latin American dance competitions. The results are as follows. First, the silhouette analysis determined that the X silhouette to the lead with, -145 costumes (78%), followed by the H silhouette at 25 (13%), and other at 16 (9%). Amongst those there were 174 one-piece dresses (94%). Furthermore, the analysis on colors of Latin American dance sports costumes revealed that, amongst the 186 costumes, 115 were without color (62%), Bl(black) is the most frequent with 37%, then Wh(white) with 21% and Gr(gray) with 4%. Costumes with colors, based on the six basic colors in the Munsell color system, are comprised most often of red with 12%, the followed by Y(yellow) at 10%, B(blue) at 8%, YR(yellow-red) at 4%, P(purple) at 2%, and G(green) at 2%. Thirdly, the cloth materials of Latin American dance costumes are recognized through image inspection. Among visually recognizable materials, beading materials are the most common with 104 costumes (60%). Shiny materials like mesh, chiffon, organza, lace and burn-out are in 36 costumes in total (19%). Other cloth materials included Luster materials and; non-sheen materials, which were in 46 costumes (25%).

Generally, in terms of the development of irrigation scheme, the efficient water resource management that supplies the irrigation water in consideration of the required time and accurate quantity to grow the crop should be conducted. The water resource assessment should precede to supply the irrigation water efficiently. The water resources assessment is divided into the water requirement analysis and the water availability assessment. In case of Korea, the major crop is paddy rice unlike crops of Africa, such as sugarcane, maize, and cassava, etc. Because it is not familiar with the method for upland irrigation development in tropical area, it needs to know the water resources assessment for irrigation scheme development about these crops. The Natama Scheme in Chiradzulu District of the Southern Malawi was selected as study area, which has tropical climate. From the collected meteorological data, the evapotranspiration was analyzed by Penman-Monteith Method and the effective rainfall was analyzed by USDA Soil Conservation Service Method. This study displays the results that for study area, the evapotranspiration varies from 2.80 mm/day to 5.51 mm/day and the effective rainfall varied from 2.1mm to 149.0mm. According to the selected crop (Green Maize, Dry Maize), the unit water requirement (UWR) and water demand (WD) considering the irrigation efficiency, irrigation time and irrigation area were estimated to be $0.00122m^3/s/ha$ and $0.0122m^3/s$ respectively. For the water availability assessment, the runoff of Natama scheme was calculated by specific yield method. The water availability was evaluated through reviewed differences of discharge between $Q80_{intake}$ and Total WD, and the irrigation water can be supplied sufficiently in the existing 10ha of Natama scheme. As a result of reviewing the extensibility of irrigable area, total WD of scheme is $0.02313m^3/s$, and $Q80_{intake}$ is $0.02387m^3/s$ ($Q80_{intake}$ > Total WD). Therefore, Natama scheme can be extended from 10 ha to 17 ha in the dry season in consideration of the $Q80_{intake}$.

This report describes the first prize design of Midongsan Eco-park, which is located in Chungcheongbuk-do (North Chungcheong) province. Criteria of the winning design are as follows: 1) The design should include a neighborhood park as well as a portion of a green zone, in order to harmonize the area ecosystem, gradually assimilate the surroundings, and serve as an education tool for the public. 2) According to an analysis of area maps and a site-inspection, a preserved area, a buffer area, a restored area, and a developed area should be developed. In the buffer and restored areas, major facilities and activity spaces should be set up. 3) Observation trails should be accessible to visitors, and a variety of adventure programs should be available. 4) The eco-park should be designed to provide a habitat for the Gorani (Chinese water deer) which used to live around Midongsan. 5) For sensuous and vivid visitor experiences, diverse programs are to be designed to accommodate different seasons, visitor ages, and required time. Environment and eco-education are to be emphasized to maximize the effect of the eco-programs. 6) Optimal activities for visitors of different ages, optimal time intervals and eco-programs by age are also suggested. 7) Facilities are zoned into three sections according to level of development. Each section has a main area and supplementary areas for better understanding. 8) Nature-friendly arrangement of facilities and construction should minimize earthwork and adverse effects on the local ecology. Throughout the planning, the following things were learned: longer-term analysis including all season's observation is essential; planning, designing, bui Iding and managing should be based on this careful, extended observation. The contest should have taken plate over a longer period of time in order enable more detailed planing of the eco-park For improved management and activities, a volunteer system in linked with schools eco-institutions and NGOs should be developed with eco-interpreters.

Leaf spot symptoms were observed in a commercial Palenopsis cultivated fields. Circular-elliptical watersoaked spots surrounded by a light green or yellow halo and turned to black when it was severe infection or blacken with gathered symptoms. These spots were finally enlarged to form of larger areas. Under the favorable conditions of temperature and moisture, the infection extended rapidly and dispersed to the crown and sometimes the infected plant became dead. A bacterial organism, isolated from the advancing margins of the lesions, was tested to characterize causing bacterium based on pathogenicity. The biochemical and physiological tests of that bacterium identified that as an Acidovorax avenae subsp. cattleyae. Therefore, we suggested to call that the new Phalaenopsis disease was bacterial brown spot caused by A.avenae subsp. cattleyae in Korea.

Pre-mRNA splicing further increases protein diversity acquired through evolution. The underlying driving forces for this phenomenon are unknown, especially in terms of gene expression. A rice alternatively spliced transcript detection microarray (ASDM) and RNA sequencing (RNA-Seq) were applied to differentiate the transcriptome of 4 representative organs of Oryza sativa L. cv. Ilmi: leaves, roots, 1-cm-stage panicles and young seeds at 21 days after pollination. Comparison of data obtained by microarray and RNA-Seq showed a bell-shaped distribution and a co-lineation for highly expressed genes. Transcripts were classified according to the degree of organ enrichment using a coefficient value (CV, the ratio of the standard deviation to the mean values): highly variable (CVI), variable (CVII), and constitutive (CVIII) groups. A higher index of the portion of loci with alternatively spliced transcripts in a group (IAST) value was observed for the constitutive group. Genes of the highly variable group showed the characteristics of the examined organs, and alternatively spliced transcripts tended to exhibit the same organ specificity or less organ preferences, with avoidance of 'organ distinctness'. In addition, within a locus, a tendency of higher expression was found for transcripts with a longer coding sequence (CDS), and a spliced intron was the most commonly found type of alternative splicing for an extended CDS. Thus, pre-mRNA splicing might have evolved to retain maximum functionality in terms of organ preference and multiplicity.

We report for the first time highly efficient trans-reflective color filters capable of demonstrating coloration in both transmission and reflection modes by taking advantage of a multilayer stack consisting of MgF₂ and TiO₂ used respectively as the low and high index materials. In order to enable such trans-reflective performance, securing an optimal stop band assuming an appropriate bandwidth within the visible regime is pivotal, which was realized by tailoring the thicknesses and the numbers of TiO₂-MgF₂ bi-layers. Three devices were designed through rigorous simulations and developed via e-beam evaporation to demonstrate vivid blue, green, and red colors in the reflection mode, and yellow, magenta, and cyan colors in the transmission mode, featuring an enhanced efficiency exceeding 90% under normal incidence. The color performance of the filters was examined by referring to the chromaticity coordinates of the transmission and reflection spectra, alongside photographed color images. The dependence of the performance on the angle of incidence was explored with respect to incident polarization, indicating that a transmission surpassing 60% could be stably maintained up to an angle of 75°. Polarization independent transfer characteristics were especially achieved for the normal incidence. The proposed devices may be readily extended to other spectral regimes by adjusting the thicknesses of the films.

In this study, we studied solar cell and fuel cell. To estimate the technology competitiveness, we used patent analysis using patent information and delphi method. For patent analysis, PII indicating the impact of patent was used. Also to analysis PII, citations data of registered and published patent were used from 2001 through 2010 in the United States, Japan, South Korea and the European Patent Office. And the delphi method results of the 'International trend analysis on the Green Energy Technology and the establishment of international cooperation models(2009)' were cited to estimate the technology level. According to the analysis results, Korea's patent registration growth rate was fairly high, but the patent impact and technology levels were significantly lower than in the United States, Japan and Germany. Especially in the solar cell, United States's PII is 1.8, but Korea's PII is 0.2. And the technology level of United States is 7 to 8, but Korea's is 5 to 6. Therefore, to improve technology competitiveness, Korea need to enhance the core technology R&D, and set up the consumer-oriented R&D strategy for commercialization from R&D planning phase. In this study, we analysed competitiveness of renewable energy which is not actively discussed. But there are limitations of the study because we used the result of past research and patent data in the past 10 years. Therefore to accurate research the period of patent data should be extended. Finally diverse indicators for measuring the technology competitiveness should be researched and developed.

The current surveys of Ulva in the subtidal area around Jeju Island give a chance to discover unrecorded green algal species of the Korean macroalgal flora. As a result of this investigation, we found Ulva adhaerens Matusmoto & Shimada, inhabiting the subtidal regions, up to 15 m deep, and conducted the DNA barcoding on plastid rbcL-3P and tufA regions with describing the morphological characteristics. Our specimens of U. adhaerens forms a monophyletic clade with the Japanese type specimen and U. piritoka Ngāti Kuri, Heesch & W.A. Nelson from New Zealand exhibiting each 0.3% sequence divergences, respectively, in the plastid rbcL-3P. The genetic variation of U. adhaerens clade is 1.0-3.9% in rbcL-3P and 4.8-9.8% in tufA to each Ulva species, including the generic type, U. lactuca Linneaus. The morphology of Korean U. adhaerens specimens is identical to the type specimens of U. adhaerens from Japan having the development of rhizoidal filaments from both of the cell layers of the distromatic blade and the extension of rhizoidal clumps with adhesive trait between blades by extended rhizoidal clumps at the basal blades. The thallus attachment to substrate is by numerous minute discoidal plates made up of rhizoids originating from the inner part of distromatic blades in basal. Although there are still some problems to resolve the relationship between U. adhaerens and U. piritoka in the rbcL dataset and the phylogenetic pattern of the Group II intron of rbcL, we propose the new record of U. adhaerens in Korean macroalgal flora based on the morphological characteristics of Korean specimens. Continued study of the genus Ulva by morphological and molecular assessment will delimit the species of Ulva, elucidate the relationships between them, and uncover the species diversity.

Radish kimchi is a typical side-dish in Korean traditional food and is a way of keeping vegetables for a extended period using fermentation. This study examined the classification, usage, eating history, variety, and recipes of Korean radish kimchi through ancient and modern era literature. The Korean radish kimchi were categorized into six groups: kkakttugi, seokbakji (or nabakkimchi), dongchimi, jjanji, jangachi, and jangkwa. According to the record, the eating history of radish kimchi comes from before the age of the Three Kingdom period. Radish was preserved in salt, vinegar, soybean paste or lees of fermented liquor in the early times. This pickled radish was not supposed to be watery. Radish kimchi was divided into watery kimchi (dongchimi) during the period of United Silla and the Koryo Dynasty. Kimchi was mixed with Chinese cabbage to make seokbakji or nabakkimchi. Up to the early Chosun Dynasty, the key ingredient of kimchi was radish. After the middle of the Chosun Dynasty, kimchi was mixed with red pepper powder, salted fish, soybean sauce, and various ingredients. There were many kinds of radish kimchi during the late Chosun Dynasty. In the 11 Korean recipe books published within the past 100 years, there are nine kinds of kkakttugi, three kinds of seokbakji, four kinds of dongchimi, three kinds of jjanji, nine kinds of jangachi, and five kinds of jangkwa. Kkakttugi (cubed, sliced or julienne radish) was pickled with salt, red pepper powder, garlic, green onion, oyster, sugar, salted fish, and more. Seokbakji and nabakkimchi were not as salty, so they could not be preserved as long. Dongchimi (watery radish kimchi without red pepper powder) was made of radish, water, salt, 18 side ingredients, 13 condiments, and seven garnishes. Jjanji was pickled to be very salty and was eaten during summer. Jangachi can be used as a regular side dish and is made of radish or dried radish slices pickled or seasoned with salt, soy sauce, vinegar, soybean paste, lees of fermented liquor, and spices. Jangkwa is used as a stir-fry method and has been segregated from jangachi relatively recently.

This study was conducted to investigate the vegetable eating behaviors and preferences of elementary school students by stage of change for vegetable intake. The subjects consisted of 191 fourth and fifth grade elementary school students from Gyeonggi province. The stage of change for vegetable intake was categorized into three groups: precontemplation (PC, 18.4%), preparation (P, 43.5%), and action/maintenance (A&M, 48.2%). The trend to eat a variety of foods was more distinctive as the students went from the PC to the A&M stage. The stage of change for vegetable intake was closely related with the kimchi-eating pattern of the students. The A&M group ate more vegetables than the PC group because they liked vegetables and/or wanted to prevent disease. The PC group had a lower tendency to follow recommendations for vegetable eating than the P and A&M groups. The PC group also had an incorrect notion that low vegetable consumption over an extended time would not have a big impact on their health. The vegetables of high preference for the elementary school students were potato, sweet potato, lettuce, radish, perilla leaf, cucumber, and cabbage. The vegetables of low preference were spinach, onion, balloon flower, and green pepper. The PC group had lower preferences for most vegetables than the P and A&M groups. Therefore, careful nutrition education is necessary especially for students in the PC group in order to explain the positive effects of vegetable intake and negative effects of an unbalanced diet. It is also necessary to survey students' tastes consistently and to develop recipes that encourage them to consume more vegetables agreeably.
