Because of the open data in public domains, it is easy to collect the public data. However, people find difficulty in visualizing the data in material that they actually want. Especially, A map is a difficult material to do the visualization work, without using the specific tools and learning. Therefore, in this paper, we proposed an interface tool for map data visualization that user can easily visualize various national statistics data on the map. We designed the interface by classifying the properties of the map systematically, focusing on the completion and convenience for making the map. After that, we developed a web-based application using D3.js. After user evaluation, we found that our application can visualize the map more quickly and completely than any other web interfaces for map data visualization. Users also found a higher satisfaction in operating convenience.

Land-based seaweed (Gracilaria) cultivation systems may provide products with high quality and biosafety for human consumption, as well as for other high value applications. However, a limitation for this land based system is high management costs. The objective of this study was to determine if the management costs for Gracilaria cultivation can be reduced without a decrease in productivity by using $CO_2$ injection along with a high stocking density and high photosynthetically active radiation (PAR), and commercially available fertilizers. When Gracilaria tikvahiae was cultivated at a high stocking density and high PAR, coupled with $CO_2$ enhancement, the productivity was significantly higher than that at a lower stocking density, low light without $CO_2$ injection. We also found that G. tikvahiae grown in a medium of commercially available fertilizer (Jack's Special, JS) showed a similar growth rate and productivity to that grown in von Stosch's enriched (VSE) seawater, while the cost for JS media is only 2% of the cost for VSE. These results suggest that $CO_2$ injection and commercial fertilizer may be a potential way to provide sustainability in land-based Gracilaria cultivation systems.

A pathogenic fungus causing balloon flower root rot (Platycodon grandiflorum) was isolated from naturally infected roots. The microbial characteristics of the isolated microorganism were similar to those of Rhizoctonia solani. About 500 bacterial species from field soils were screened for a biological agent against the above-mentioned putative pathogen, and several bacteria with the antifungal activity were isolated. Among them, the isolated JS2 was identified as Pseudomonas aeruginosa. This strain showed a broad spectrum of antifungal activity potentially. When the antifungal substance was purified from a broth culture of JS2, it was identified as 2,4-diacetylphloroglucinol (Phl).

In this paper, evaluation of physical properties about dielectric relaxation phenomena by the detection of the surface pressures and displacements current on the monolayer films of phospolipid monomolecular DLPC, DMPC using pressure stimulus. As a result, the changed surface pressure, displacement current and the transition forms of dipole moment of phospolipid monomolecular in area per molecular by pressure stimulus were conformed well. It was known that the monolayers by linear relationship for decision of dielectric relaxation time between compressure speed $\alpha$ and molecule area $A_m$ By according to the linear relationship relation get that frictional constant $\xi$, DLPC was $1.89{\times}10^{-19}$[Js] and DMPC was $0.722{\times}10^{-19}$[Js]. It is found that the phospolipid monolayer of dielectric relaxation takes a little time and depend on the molecular area.

Porcine epidemic diarrhea virus (PEDV) strain Chinju99, which was previously isolated from piglets suffering from severe diarrhea was used to characterize the membrane (M) protein gene to establish the molecular information, and the results will be useful in elucidating concepts related to molecular pathogenesis and antigenic structures of PEDV isolates. The Chinju99 M gene generated by reverse transcription and polymerase chain reaction (RT-PCR) consisted of 681 bases containing 22.3% adenine, 22.3% cytosine, 23.1% guanine and 32.3% thymine nucleotides, and the GC content was 45.4%. It had some nucleotide mismatches from M gene of other PEDV strains, such as CV777, Br1/87, KPEDV-9, JMe2, JS2004-2 and LJB-03 with 97-99% nucleotide sequence homology to these strains. Also, it encoded a protein of 226 amino acids, which had some mismatches from those of CV777, Br1/87, KPEDV-9, JMe2, JS20004-2 and LJB-03, as the amino acid sequence homology showed a 97-98% to these strains. The Chinju99 had a very close relationship to the Japanese strain JMe2 for the nucleotide and amino acid sequences of the M gene. The amino acids predicted from Chinju99 M gene consisted of mostly hydrophobic residues and contained three potential sites for asparagine (N)-linked glycosylation, two serine (S)-linked phosphorylation sites by protein kinase C, and two S- or threonine (T)-linked phosphorylation sites by casein kinase II.

Furniture is very important in our lives. Especially traditional wood furniture of Korea has been developed practically in the area of form, compositions, manufacturing technique and etc because of the rapid environmental changes. Jang Sung has a very efficient geographical characters to get the adequate timbers for furniture. And the late Mr Seol SeokCheol had devoted all his life to out-and-out artisan spirit for the purpose of korean wood furniture manufacturing. In this paper, l try to explain regional and cultural characteristics of JS, special designs for wood furniture of JS, manufacturing process of traditional wood furniture, especially in the center of his works. Tradition is an essential power to a country and a race. Now we are living living in the state-of-art age and we share all the cultures and merchandise globally but nevertheless, a nation and a race who has a unique tradition is still a cultural advanced country and these works of our ancestors are the best souvenir for the tourists. So we have to memorize these facts and we will have to raise and develop our power of traditional cultures, including from the traditional wood furniture.

The solid-liquid mass transfer coefficients $k_L$ in a gas-liquid-solid three phases agitated vessel were measured with conventional impellers (e.g. Rushton turbine, paddle, and propeller). For the conventional impellers the rotational speed for the complete suspension $N_{js}$ changes with the impeller height and gas flow rate. Mass transfer coefficient of the Rushton turbin impeller, for which the particle suspension was independent of the aeration, is correlated only with Pgv. Mass transfer coefficients $k_L$ for the Rushton turbine, paddle and propeller impellers were affected by the impeller position.

This paper presents a novel shore-to-sea maritime data transmission system based on time-code diversity, using visible light in maritime environments to overcome the limitations of conventional maritime wireless communications. The proposed system is primarily comprised of existing LED-based lighthouses and maritime transceivers (marine beacons, buoys, etc.), and thus is considered cost-effective in terms of implementation. We first analyze maritime visible-light communications on the basis of the unique properties of a maritime environment, i.e. sea states (wave height, wind speed, etc.), plus atmospheric turbulence, using the Pierson-Moskowitz (PM) and JONSWAP (JS) spectrum models. It is found that the JS model outperforms the PM model, and that the coverage distance depends on the LED power and sea states. To combat maritime fading conditions that significantly degrade performance and coverage distance, we propose a time-code diversity (TCD) scheme in which the delayed versions of the original data are retransmitted using orthogonal Walsh codes. This TCD scheme is found to be superior, in that it offers three orders of magnitude in terms of BER performance, compared to a conventional (non-TCD) transmission scheme. The proposed scheme is robust and efficient in overcoming the effect of impairments present in maritime environments with a BER of approximately $10^{-5}$and a data rate of 100 Kbps at a distance of 1 km.
