With lots of portable convergence mobile device coming out into the market, companies are now facing to take up consumers' needs. The products are popularized by 'skin function' in the field of hardware, whereas software wise, it's still a long way to follow up the needs. It's been hypothetically known that the Image of Sensitivity Adjective chosen by the users can increase the brand image and value creating capabilities through visualization. We collect the 'adjective' of images of recent products first and on that base, we sort out the most popular 'adjective' through grouping, then we actualize the image with that sample collective body. Then through analyses of the image, we find how they are correlated and what their elements are with the result.

Background: Tobacco use is one of the leading causes of preventable death across the world today and the smoking rates among men in the Arab world are amongst the highest in the world. Smoking of dokha, a traditional Arab tobacco is common in some of the Middle East countries such as the United Arab Emirates and Iran. This review focuses on the prevalence, pattern and health effects of dokha use in the Middle East. For this purpose an electronic search was performed in the following databases and websites: MEDLINE, EMBASE, Proquest and Google scholar up to December 2012. The search strategy was based on Internet search for the synonyms of dohka or midwakh. From the results of the review it emerged that younger people are the most common users of dokha. Hence effective outreach health education programs, targeting adolescents, especially school students before they take up the habit of smoking, may thus curb the emergence of the problem.

Recently, domestic datawarehouse marketplaces take up the most important part of information technology investments with ERP(Enterprise Resource Planning), EC(Electronic Commerce) construction projects in spite of a business slowdown for IMF environment. Therefore, in industrial fields as finances, communications, manufactures, distributions, and so on, datawarehouse was constructed or is under construction, and datawarehouse success stories was showed around some enterprises that has constructed previously datawarehouse. This study is intended to be henceforth an index and direction for an actual proof study by discussing a study of methodology for datawarehouse construction in order to compare and analyze Top-down & Bottom-up approach for datawarehouse that has constructed in actual enterprises.

With the advent of the 21th century, Korea surrounded by the three sides of the sea has been underlining the fact that it will become one of the strongest maritime powers near future as ever in the past. The study shows that in order to build up Korea as a powerful maritime country, not only should we urge its government to take more in-depth political interest in the field of the shipping industry, but the effective training and the managing program for sea-farers employing in th forefront of the shipping business(as the centric panel of the competent merchant marine officers) also have to be taken into a sufficient consideration. According to the large scale, higher speed and automatization of vessels, a number of seamen who have so well-workable brain as to dexterously operate the up-dated scientific equipments have come into be demanded. This study therefore has not only suggested that an improvement for the system of the education for merchant marine officers and the effective scheme of the management on them, but especially underlined the problems of seamen' and their families' economic and social securities as well.

Three-dimensional mesh models have been widely used in various applications such as simulations, animations, and e-catalogs. In such applications the normal vectors of mesh models are used mainly for shading and take up the major portion of data size and transmission time paper over networks. Therefore a variety of techniques have been developed to compress them efficiently. In this paper, we propose the MOEC (Modified Octree Encoding Compression) algorithm, which allow multi lever compression ratios for 3D mesh models. In the algorithm, a modified octree has nodes representing their own positions and supporting a depth of the tree so that the normal vectors are compressed up to levels where the shading is visually indistinguishable. This approach provides efficient in compressing normals with multi-level ratios, without additional encoding when changing in compression ratio is required.

We study the dust and star-formation characteristics of a nearby dwarf elliptical galaxy, NGC 855. With various archival data from ultraviolet to far-infrared, we build up the spectral energy distribution (SED) that can give us constraints on stellar populations, dust characteristics, star-formation history, etc. From GALEX and SDSS data, slightly de-centered bluer central core is confirmed, where star formation might take place. This regions is coincident with seemingly dis-integrated cores detected by Spitzer IRAC data and with bright Ha feature observed at ground-based telescope. The PACS and SPIRE data by Herschel Space Observatory show the dominant dust features at the center. Lastly, we propose necessary follow-up observations with ground-based telescopes to investigate spectral properties of NGC 855.

Particle size distribution in a Continuous Mixed Suspension Mixed Crystal Removal (CMSMPR) crystallizer has been analyzed using the Population Balance (PB) model. This method presents difficulties when the growth rate of crystal depends on the crystal size. Recent studies indicate that in many cases the growth rate is dependent on size when the crystal sizes are small. In this study, a Residence Time Distribution(RTD) model was proposed to take the size dependence into account together with an appropriate numerical scheme. When compared with the approximate results based on PB model, RTD model results showed improvements also a nucleation effect which is normally unimportant for steady state analysis. Start-up data for NaCl-Water-Ethanol system was compared with computed values.

Many researchers are studying on humanoid robots in all over the world. However the humanoid robots are still limited in doing works like picking up objects on the ground or moving rapidly. In this study, a humanoid robot based on the wheel-driving was developed. It can operate with a human working area keeping the stability. Also, the developed robot can take up the object on the floor since it has knee(1DoF) and waist(3DoF), and do service quickly and steadily. The hardware and software structure and algorithms of the developed robot, SEROPI are introduced in this paper.

In this paper, it is described on the exportation trend and future development paradigm of the localized small aircraft which was recently developed four seated canard type aircraft for exportation purpose. Presently, even though the development of small aircraft is recessed, if we start development of the proper airplane models by integrating domestic power of industry-university-institute on the base of research experience from now on, we can go into the global market and take up the level of world top 10 makers without doubt. For successful operation of exportation system of small aircraft, it is needed to set up development strategy paradigm by forming consortium centering around the medium and small enterprises.

Thermotropic liquid crystalline polymer made up of poly(p-hydroxybenzoate) (PHB)-poly(ethylene terephthalate)(PET) 8/2 copolyester, poly(ethylene 2,6-naphthalate) (PEN) and PET were mechanically blended to pursue the liquid crystalline phase of ternary blends. Complex viscosities of blends decreased with increasing temperature and PHB content. DSC thermal analysis indicated that glass transition temperature (Tg) and melting temperature (Tm) of blends increased with increasing PHB content. Both tensile strength and initial modulus increased with raising PHB content and take-up speed of monofilaments. In the WAXS diagram, only PEN crystal reflection at 2Θ=$15.5^{\circ}C$ appeared but PET crystal reflection was not shown in all compositions. The degree of transesterification and randomness of blends increased with blending time but sequential length of both PEN and PET segment decreased.
