Recently, Phising attack uses trick of URL and sites, and technical concealment method which infiltrates sophisticated malicious code. However, sometimes Phising security technology cannot cover all of Phising methods. Consequently, this research proposes inspection to solve this problem. First, we can install Proxy server for a strong open information exchange of web environment between web servers and clients. Therefore, it compares and analyzes harmful site and Phising URL with White domain list, and filters them. Finally, designs for stable web based information so that we can block Phising with least regulation and active control. So the purpose of this paper is introducing this design system and structure, and inspect them.

In the communications systems with diversity, we are commonly faced on needing of new source coding technique, error resilient coding. The error resilient coding addresses the coding algorithm that has the robustness to unreliability of communications channel. In recent years, many error resilient coding techniques were proposed such as data partitioning, resynchronization, error detection, concealment, reference picture selection and multiple description coding (MDC). Especially, the MDC using correlating transform explicitly adds correlation between two descriptions to enable the estimation of one set from the other. However, in the conventional correlating transform method, there is a critical problem that decoder must know statistics of original image. In this paper, we propose an enhanced method, the MDC using whitening transform that is not necessary additional statistical information to decode image because the DCT coefficients to apply whitening transform to an image have uni-variance statistics. Our experimental results show that the proposed method achieves a good trade-off between the coding efficiency and the reconstruction quality. In the proposed method, the PSNR of images reconstructed from two descriptions is about 0.7dB higher than conventional method at the 1.0 BPP and from only one description is about 1,8dB higher at the same rate.

This study is on the image of a woman's body exposure, expressed in various situations or images in the modern fashion. The results of this study can be summarized as the following. First, either the exposure or stress of a woman's specific body parts like breast, waist, hips, or legs which can be sensed totally different from man's or the ironic disclosure of body parts always lapped around emphasizes femininity by giving full play the unique sexual beauty of a woman's body. Second, the desire of disclosure to have others' attention with the concealment as suggestive exposure expresses the eroticism. The modified eroticism is found different from the conventional concept and is based on the desire to make others notice one's existence continually by the sexual exposure dress particularly to entire the other sex, the dismantlement of changing an underwear to an outer-dress, and so forth. Third, both exposure of a woman's sexual body parts and expression of exposure to the utmost by laying a woman's entire body bare can mean sex liberty in the laissez-faire generation. This may suggest a pleasure-oriented way of thinking of the self-consolation rather than showing others, or feature the personality and the liberty endowed women with.

The goal of auricular cartilage harvest is to obtain a sufficient amount for reconstruction and to minimize the change in ear shape. The cartilage can be harvested by a posterior or anterior approach, and each method has advantages and disadvantages. The posterior approach presents the advantage of scar concealment, but there are limits to the amount of cymba cartilage that may be harvested. In contrast, the anterior approach may cause a noticeable scar. However, as cartilage is collected, the anterior approach provides a view that facilitates the preservation ear structure. In addition, it is possible to obtain a greater amount of cartilage. From January 2014 to December 2015, we harvested auricular cartilage graft material in 17 patients. To prevent the development of trapdoor scars or linear scar contracture, short incisions were made on the superior border of the cymba and cavum. Two small and narrow incisions were made, resulting in suboptimal exposure of the surgical site, which heightens the potential for damaging the cartilage when using existing tools. To minimize this, the authors used a newly invented ball-type elevator. All patients recovered without complications after surgery and reported satisfaction with the shape of the ear.

The following study has examined possible methodological approach and prospect of implementing storytelling in rural tourism field. It is aimed towards deducing principles of space composition behind securing placeness of rural tourism village through storytelling. The research had been conducted by archival research and case study on field of interest, and its findings are as follows: 1) Storytelling exhibits principles of narrative structure (exposition, complication, climax, and resolution) in various fields, and has shown tendency to structuralize a plot. 2) It can be said that storytelling is deeply related with people's associations of their inner mind. This can be a logical explanation of a certain sight or location, which is a physical environment itself being the actual narrator and distributor in storytelling. 3) In order to convey a story in a more convincing way, storytelling a naming strategy based on a rhetorical technique, which has been shown to positively influence creating unique placeness of a rural village. As indicated in our study, means of storytelling-"Continuity and tourist circulation of space composition with a narrative structure, spatial hierarchical order, concealment and revelation, cast, and naming based on rhetorical technique and facilities positioning"-is a viable solution that can bring recovery of the rural village's unique placeness, as well as spatial development for sustainable rural tourism.

Psychoanalytical film theory promoted by Metz supplied theoritical base in analyzing the effects of mass culture to subject. This theory may be also applied to computer games, so that we would promote studies in depth about game critics and game culture. In this article, first inspected the theories of Freud and Lacan and then examined the psychoanalytical film theory by Metz and Baudry. Computer games analyzed by the frame of artificial regression, first identification and concealment of marks of enunciation. As a result, computer games appeared that deeply effect to the subject similarity cinema.

Reversible DNA watermarking is capable of continuous DNA storage and forgery prevention, and has the advantage of being able to analyze biological mutation processes by external watermarking by iterative process of concealment and restoration. In this paper, we propose a reversible DNA watermarking method based on histogram multiple shifting of noncoding DNA sequence that can prevent false start codon, maintain original sequence length, maintain high watermark capacity without biologic mutation. The proposed method transforms the non-coding region DNA sequence to the n-th code coefficients and embeds the multiple bits of the n-th code coefficients by the non-recursive histogram multiple shifting method. The multi-bit embedding process prevents the false start codon generation through comparison search between adjacent concealed nucleotide sequences. From the experimental results, it was confirmed that the proposed method has higher watermark capacity of 0.004-0.382 bpn than the conventional method and has higher watermark capacity than the additional data. Also, it was confirmed that false start codon was not generated unlike the conventional method.

It is the law that injured workers must be paid compensation through occupational health and safety insurance. But sometimes, construction companies cover the compensation for an accident by themselves in order to conceal the fact of an accident. The reason for this concealment is that they wish to get a high mark in PQ. From the point of view of a subcontractor, another reason is to avoid any negative consequences in bids. According to interviewees, some workers, knowing the vulnerability of their employers in this area, demand unreasonable levels of compensation. This study examined the circumstances, influences and participants' perception of accidents on construction sites.
