The advancement of information technology and the popularization of Internet has explosively increased the amount of multimedia contents. Therefore, the requirement of multimedia recommendation to satisfy a user's needs increases fastly. Up to now, CF is used to recommend general items and multimedia contents. However, general CF doesn't reflect visual characteristics of image contents so that it can't be adaptable to image recommendation. Besides, it has limitations in new item recommendation, the sparsity problem, and dynamic change of user preference. In this paper, we present new image recommendation method FBCF (Feature Based Collaborative Filtering) to resolve such problems. FBCF builds new user profile by clustering visual features in terms of user preference, and reflects user's current preference to recommendation by using preference feedback. Experimental result using real mobile images demonstrate that FBCF outperforms conventional CF by 400% in terms of recommendation ratio.

South Korea became the country where there is the most plastic surgery per person in the world. Plastic surgery already has been the core part in the beauty industry. Therefore, in order to understand the beauty industry, we studied the characteristics of the plastic surgery's websites. From 2006 to 2011, we researched total number of 407 plastic surgery websites including, 166 the most visited plastic surgery websites, 241 comparing of bench mark websites. The collected data was analyzed by using the method of Multiple Discriminant Analysis(MDA). As a result of the research, firstly, the most visited plastic surgery websites were not a contents provider but a community website, secondly, well organized and actively adaptable of the rapid changes from environment. In addition, there were also competitiveness to become the most visited plastic surgery website and by the possibilities, the relatively large size of plastic surgery had high probability to own the most visited website. This research paper is looking forward to be used as the understanding the e-business of the plastic surgery.

In other to establish the exact determination method of amino nitrogen (AN) in salt-fermented fish sauces, we determined the AN in fish sauces according to the measuring methods and also investigated the main factors influencing on determination method of AN. AN in salt-fermented anchovy sauce increased linearly as fermentation progressed, and was shown the highest amount measuring by the Formol method, followed by the trinitrobenzene sulfonic acid (TNBS) method and the Copper-salt method. AN concentration in anchovy sauces fermented for 12 months was $88.2\%$ and $77.6\%$ for the TNBS method and the Copper-salt method, respectively, on the basis of Formol method. The ratio of AN/total nitrogen (TN) in anchovy sauce fermented for 12 months was higher than that in commercial anchovy sauces. The determination of AN in anchovy sauce by the TNBS method was not affected by salt concentration, and slightly affected by heating. The effect of MSG on AN contents by Copper-salt method was shown higher than those by the Formol method and the TNBS method. The TNBS method was adaptable to measure the content of AN in fish sauce by this study.

Structural control through integration of passive damping devices within the building structure has been increasingly implemented internationally in the last years and has proven to be a most promising strategy for earthquake safety. In the present paper an alternative configuration of an innovative energy dissipation mechanism that consists of slender tension only bracing members with closed loop and a hysteretic damper is investigated in its dynamic behavior. The implementation of the adaptable dual control system, ADCS, in frame structures enables a dual function of the component members, leading to two practically uncoupled systems, i.e., the primary frame, responsible for the normal vertical and horizontal forces and the closed bracing-damper mechanism, for the earthquake forces and the necessary energy dissipation. Three representative international earthquake motions of differing frequency contents, duration and peak ground acceleration have been considered for the numerical verification of the effectiveness and properties of the SDOF systems with the proposed ADCS-configuration. The control mechanism may result in significant energy dissipation, when the geometrical and mechanical properties, i.e., stiffness and yield force of the integrated damper, are predefined. An optimum damper ratio, DR, defined as the ratio of the stiffness to the yield force of the hysteretic damper, is proposed to be used along with the stiffness factor of the damper's- to the primary frame's stiffness, in order for the control mechanism to achieve high energy dissipation and at the same time to prevent any increase of the system's maximum base shear and relative displacements. The results are summarized in a preliminary design methodology for ADCS.

A new HPLC-method for separation and quantitative determination of ginsenosides in Panax ginseng, Panax quinquefolium and in pharmaceutical drug preparations is elaborated. A reversed-phase-system with ${\mu}Bondapak\;C_{18}$ column (3.9 mm $I.D.{\times}30\;cm$) using acetonitrile-water (30:70) 2 ml/min and acetonitrile-water (18:82) 4 ml/min is suitable for the base-line separation of $Rb_1,\;Rb_2,\;Rc,\;Rd,\;Rf,\;Rg_2,\;respectively\;Re,\;Rg_1$ in 30 minutes. The ginsenosides are directly detected at 203 nm (without derivatization) with the LC-55 or LC-75 spectrophotometer (Perkin-Elmer) at $100\%$ transmission. Detection limit is 300 ng at a signal-to-noise ratio of 10:1. The ginsenosides-peak identification is carried out with HPTLC (high performance thin layer chromatography), with MIR-IR (multiple internal reflection-IR-spectros-copy) and with FD-MS (field desorption mass spectrometry). The calibration curve of each ginsenoside has a correlation coefficient very near to 1. Relative standard deviation for quantitative determinations depends upon the amount of ginsenosides and is approximately 1\%$ for ginsenoside contents of 1\%$. This method is adaptable for routine analysis in quality control laboratories.

Choi Dong-hoon's films tend to have not been well treated academically in Korea. But from the point of view that his works have succeeded in box office and survived in the market for some reason, there seems to be new possibilities to treat them. In this paper, the two movies with ten million audiences, and that are Choi's original scenario and caper film genre are tried to examine the success factors in box office on "making well made story". Often, well-made films have both genre-customary and creative aspects. Choi Dong-hoon's movies are the same. and faithfully follow the rules of caper film genre. At the same time, these two films have complex adaptive systematic creativity, in which multiple characters are self-organizing with their story patterns actively. And since there is a proper coexistence of customary and original aspects in the and , these two films are seemed to be at the edge of the chaos, which is the most market adaptable.

This study is a clinical single case study of the application of Theraplay approach for the treatment of children with eating disorder based on Polyvagal Theory. The first research question is how children with eating disorder change through Theraplay. The second research question is to analyze what the therapeutic factors are for changes in children with eating disorder. To do this, I used a qualitative case study method that explores a small number of cases closely and reveals the case deeply. As a result, the client has a sense of security in Theraplay session, expands the window of tolerance and develops a social engagement system. Through these, client become increasingly adaptable and overcome eating disorder. The results of this study can contribute to neuroscience validation of the counseling effect.

The worldwide population is aging rapidly. In this circumstance, Korean society is in need of the urgent comprehensive countermeasures that will help the elderly with their health problems and infection control in their daily life. Universal design has supportive, adaptable, accessible and safety-oriental design standards for the elderly. Is this study, we propose the guidelines of the mobile application development based on the application of the universal design for infection control in the elderly. From the perspective of the universal design, there are several important guidelines including 'generalized access', 'simple and intuitive usage', 'low physical effort', and 'visualized language' based on the KCDC(Korea centers for disease control and prevention) principles for the elderly. These findings show that the guidelines for improving the health literacy of the mobile application via universal design are necessary to enhance the health behavior of infection control for the elderly.

Critical practicality problems are cause to search the presentation and contents according to user request and purpose in previous internet system. Recently, there are a lot of researches about dynamic adaptable ontology based system. We designed ontology based educational system which uses discrete probability and user profile. This system provided advanced usability of contents by ontology and dynamic adaptive model based on discrete probability distribution function and user profile in ontology educational systems. This models represents application domain to weighted direction graph of dynamic adaptive objects and modeling user actions using dynamically approach method structured on discrete probability function. Proposed probability analysis can use that presenting potential attribute to user actions that are tracing search actions of user in ontology structure. This approach methods can allocate dynamically appropriate profiles to user.
