A new silkworm variety, Juhwangjam, was bred for the producing of light pink colored cocoon. The Juhwangjam variety was selected and succeeded from the F1 of 2303 × BP Heehong in 2016 autumn. Hatchability (96%) and pupation percentage (97.6%) of Juhwangjam was matched to the authorization criteria for commercial silkworm variety. Laval period and other economical characters of Juhwangjam were similar to the authorized silkworm variety, Goldensilk. Cocoon yield of Juhwangjam in spring and autumn season was 20.0 and 14.3 kg, respectively. Therefore, a new silkworm variety, Juhwangjam for light pink cocoon, might be adaptable to culture in spring season rather than autumn season.

As it gets nearer to the modern society, social and cultural situations are changing and the spatial form of public space is changing into the complex structure where it is interlinked with each other diversely. In particular, as the development of large-scale complex spreads nationwide, the form of complex commercial space assuming the nature of malls appears prominently. In such a large-scale complex commercial space, the diverse visual elements make the environment difficult to be perceived. Like this, the attention in the commercial space where a variety of visual stimuli are in the presence, is important element, so the plan of VP(visual presentation) is needed for effectively selecting or inducing the space. Thus, in this study, human visual and perception process will be reviewed and a method to evaluate the attention will be proposed. Also, the attention of each stores in the complex commercial spaces will be evaluated to propose the indicators for resonable spatial panning in the future.

Pyropia, economic red algae species, have been cultivated in Korea (referred to as 'gim'), Japan ('nori'), and China ('zicai') for over 300 years. Vegetable seaweed Pyropia species are sold in the public markets in various forms as commercial seafoods. In Korea, two kinds of Pyropia seafood made with species of Pyropia and Ulva (sea lettuce, referred to as 'parae') are also sold. These are referred to as 'parae-gim' (with Pyropia spp. and U. linza) and 'gamtaegim' (with Pyropia spp. and U. prolifera). There is currently no method for identifying the seaweed species that comprise Pyropia seafood products. Therefore, we developed novel molecular markers to identify Ulva species in commercial Pyropia seafoods. Based on rbcL molecular markers, we identified informative characteristics to discriminate U. linza and U. prolifera as seafood ingredients. Moreover, PCR with 3'-end mismatch primers successfully isolated the specific rbcL sequences of U. linza and U. prolifera from Pyropia seafoods. Therefore, our novel molecular markers will be useful for identifying the ingredient species of commercial seafoods.

Recently, the roof garden of the large commercial facilities has been changed as a complex cultural space follow the users' diverse needs. It is focused on large commercial facilities on Seoul and Gyeonggi area but large commercial facilities of the province still has not been able to respond to the needs of users. Thus, the present condition of roof gardens was compared space components with physical environmental factors in Seoul, Gyeonggi and Daejeon, Chungcheong. Throughout the comparison, roof gardens in Daejeon and Chungcheong area were focused on finding ways to improve As a result, roof gardens in Seoul and Gyeonggi area were applied to a variety of factors in space components experience, learning, performance, exhibition and etc. It is composed to take place of various acts in the roof garden. On the other hand, roof gardens in Daejeon and Chungcheong were not applied a variety space components by comparing Seoul and Gyeonggi area. Physical environmental factors also were insufficient by comparing Seoul and Gyeonggi area the landscape, awning facilities, amenities for handicapped. As described above, space components and physical environmental factors in Daejeon and Chungcheong area roof gardens were insufficient. To perform the role of the roof garden changing as a complex cultural space and to confront to the users' needs space component such as learning, performance, exhibition should be considered during planning. And physical environmental factors supportable space components should be considered together.

Following to current interior design that becoming more varied and composite, minimal tendency has also been changed. Furthermore, according to the lapse of time, minimalism, a space design, has been developed in a new look among such complex trends. Therefore, in this study, changes of tendency into a style of minimalism and characteristics thereof shown in interior design amid current of times were carefully reviewed, and local and foreign artists together with their works were investigated and analyzed having focused on the inclination of minimalism displayed in interiors of commercial spaces, especially before or after 2000s by dividing them into distinctive features in connection with space, material and type. It is thought that the interior space under the concept of minimalism will be changed and developed further in a variety of shapes to suit the environments in the current era getting rid of simple physical characteristics.

Though a variety of non-conventional feedstuffs have been successfully evaluated in research stations in Asian countries, there had been little adoption of these technologies at the small farm level. The methodology and results of three separate on-farm trials evaluation the possible use of some non-conventional feedstuffs in broiler diets under small farm conditions in Sri Lanka are reported in this paper. In all trials, the commercial mash, that in normally used in the farms, served as the control. In trials 1 and 2, 5 and 10% cassava leaf meal, respectively, was substituted (w/w) for the commercial mash and fed to broilers for six weeks. In trial 3, several non-conventional feedstuffs (cassava leaf meal, rubber seed meal, ipil ipil leaf meal and died poultry manure) were substituted (w/w) for the commercial mash at levels of 15-20%. The results demonstrated that these non-conventional feed resources can be used in broiler diets under small farm conditions, with no adverse effects on performance. The salient features of on-farm animal research are highlighted.

Commercial vehicle ESC assessment for curvature road was conducted. The previous study of ESC activation condition for losing controllability utilizing the test protocols of double lane change and sine with dwell method was conducted without considering the geometric complexity of roadway design. Since critical rollover accidents were frequently observed in the exit ramp zone, variety of curve, slope and bank have been added for analysis conditions. Detailed feature of the ramp including location, dimension and design characteristics have been analyzed from the typical trumpet type ramp design. Analyzing accident data from 2008, two specific ramps have been selected due to their complexity in design and severity in steering operation.

Installation art in 20th century shows an expanded trend as a result of material, time, or spatial expansion of subject, therefore subjects could be either materials or non-materials. This trend says that three elements-objet, space, and spectator-is inseparable essence of installation art. Nowadays, the borderline between installation art and everyday human life is getting indistinctive, and both Installation art and human life are becoming a part of another. By adapting the flexibility of installation art into the interior space, more interaction could happen, therefore, people will recognize spatial and visual character of Interior space as a visually satisfying Installed object. The main goal of this study is to understand changing of spatial composition in consequence of expressional variety as a result of dispersion of spatial elements. Especially, this study gives a fundamental ideas about private character of installations art in commercial spaces and expressional character of modern installations.

We determined the genetic relatedness among 81 commercial varieties of oyster mushrooms by either comparison of fruiting body characteristics or using PCR amplification with URP primers. Also, we assessed their temperature adaptation by using box cultivation. Based on our data, some varieties such as Wonhyung and variety 1, Suhan and variety 20, Wang-hukpyung and variety 4, Chunchu #2 and variety 6, Shinong #11 and variety 1, Samgu #1 and variety 2, showed the close genetic relatedness between each other. It is known that mushroom culture room is affected by outer temperature because mushroom need the adequate aeration for their growth. Therefore, in aspect of saving energy, the cultivation of season favorable mushroom species has been recommended. Eight different commercial varieties including Sa-chul, Yeoreum and Bunhong(Pink) grew well at high temperature ($16^{\circ}C$). Also, about 51 different oyster mushroom strains were good at relatively high temperature. However, other 64 different oyster mushroom varieties were grew well at low temperature ($11^{\circ}C$). Fourty-nine varieties were adapted well in most temperatures. The slow growth rate were observed in some varieties including Kun(P. eryngii ), Awi(P. nebrodensis ), and Cheunbok(P. abalonus ), which are not suitable for box cultivation. We believe that the culture characterization of each mushroom varieties should help many farmers in many aspects such as saving energy, quantity improvement and new variety development etc.

Using commercial radish varieties for processing, about 30% of radish was discarded due to the root shape and low purity. To raise the processing ability, we tried to develop a new variety producing H-shaped root. As another characteristic required in variety for processing is high purity, we tried to raise purity using simple sequence repeats (SSR) markers for testing seed purity in every segregating generation. To develop Male-sterile (MS) seeding parent, we crossed commercial variety of 'Gwan dong spring' and 'Gyeo ryong spring'. One elite inbred was selected as recurrent parent for the MS plant. The major horticultural traits of selected inbred line were disease resistance, late bolting, heat resistance and bright green root top color. To develop pollen parent, we crossed commercial variety of 'Tae sang king' and 'Seoul spring'. We used individual selection method to develop H-shaped hard root and disease resistant inbred. In each segregating generation, we selected one plant based on phenotype and the uniformity of selected plant was tested by SSR markers using self-pollinated seeds. In the first segregating generation, 64.6% of sib plants shared the same band in PCR amplification using ACMP-490 primer and 66.7% using cnu-316 primer. The uniformity of segregating generations using ACMP-490 and cnu-316 raised in second generation to 68.8%, 70.8%, respectively; in third generation to 93.8%, 100%; in fourth generation to 93.8%, 100%; in fifth generation to 95.8%, 100%; in sixth generation to 100%, 100%. A novel cross was made using selected MS parent and pollen parent. When we checker the horticultural traits using autumn cultivation, the novel cross variety produced H-shaped root comparing other commercial varieties and produced highly uniform radish. Thus we registered this novel cross variety as 'YR ORE' at 2013 (Registration No. 4550).
