Smartphones have all the recent technology integration and NFC (Near Field Communication) Technology is one of them and become an essential these days. Despite using smartphones with NFC technology widely, not many security vulnerabilities have been discovered. This paper attempts to identify characteristics and various services in NFC technology, and to present a wide range of security vulnerabilities, prevention, and policies especially in NFC Contactless technology. We describe a security vulnerability and an possible threat based on human vulnerability and traditional malware distribution technic using Peer-to-Peer network on NFC-Enabled smartphones. The vulnerability is as follows: An attacker creates a NFC tag for distributing his or her malicious code to unspecified individuals and apply to hidden spot near by NFC reader in public transport like subway system. The tag will direct smartphone users to a certain website and automatically downloads malicious codes into their smartphones. The infected devices actually help to spread malicious code using P2P mode and finally as traditional DDoS attack, a certain target will be attacked by them at scheduled time.

The purposes of this study are to look into the formative characteristics of the bolero and to evaluate the visual effects and images according to changes in the line and length of the connecting lines of the neck, center front, and hem lines from analyzing the bolero style shown in 2005 S/S domestic fashion. Theoretical examination of the bolero was made philologically with reference books, theses and some articles. And the bolero style shown in 2005 S/S domestic fashion was analyzed with pictures from a fashion magazine "Ceci" and a fashion website 'Interfashion Planning" from Feb. to Aug. of 2005. As a result, the basic lines of the bolero are classified into three different categories according to the connecting lines of the neck, center front line, and hem line. We altered the length of the bolero in three categories with the changes in the waistline-5 cm, 8 cm, and 11 cm. For the visual evaluation, 9 stimuli were placed in mannequins, and were estimated by the experts in the fashion design. For the visual evaluation according to changes in the line and length of the bolero, we used 12 pairs of items to find the visual effects, and 13 pairs of adjectives to measure the visual images. The stimuli and adjectives were randomly given to the evaluators and were evaluated by the 7-Point Likert Type Scale. Data we got from this experiment was analyzed statistically by using the SPSS 12.0 and practiced the Factor Analysis and Correlation Analysis. In the current women's garments, the bolero is a new fashion item which combines with jackets or cardigans. Usually the bolero jacket is made out of a cotton, denim, leather or fur, and the bolero cardigan usually used knitted materials. The design could be very varied depending on the roundness of the center front line, and hem line. According to the result of factor analysis of the visual effects of the Bolero, four factors were identified the whole silhouette, neck line, breasts and shoulders. According to the result of factor analysis of the visual image of the Bolero, three factors were identified maturity, tenderness, neatness.

The purpose of this study was to propose various directions for effectively proposing window displays that satisfy changing consumer needs by investigating and analyzing the characteristics of unexpected expressions used in recent Christmas windows. Research was conducted by investigating unexpectedness in window displays through literature reviews and previous studies. To observe unexpectedness in Christmas windows, website-based case images of window displays from the six years between 2010 and 2015 were collected from the department stores of Bergdorf Goodman, Printemps, Selfridges, and Isetan. Unexpected expressions in department-store Christmas window displays could be categorized into four expressive methods of hybrid expressions, figurative expressions, amusing expressions, and exaggerative expressions. The results were as follows: First, hybrid expressions are interpreted by consumers as having new or diverse meanings that change the original external forms of subjects or objects. Second, Christmas colors are used in the window backgrounds' figurative expressions, but these windows do not use excessive expressions; furthermore, these windows personify people as animals and anthropomorphize animals as people, using subjects to depict other subjects to show unfamiliar images. Third, amusing expressions are used to decorate windows with unique and novel ideas that provide stimulation and amusement for customers and capture their attention through the composition of windows that entail childish props and elements that create funny. Fourth, exaggerative expressions deliberately stretch and expand subjects or objects in windows to elicit customers' curiosity and interest through emphasis.

This study analyzed the effect of perceived interactivity in health information websites on users. First, this study analyzed the effect of users' individual characteristics on the perceived interactivity. As a result, hypochondriasis had a negative relationship with perceived interactivity, and health literacy had a positive relationship with it. On the other hand, although the perceived interactivity had a positive effect on users' attitudes toward health information websites and expected outcomes, it did not have an effect on continuous usage intention. However, their attitudes and perceived outcomes had a positive influence on continuous usage intention and at the same time mediated the perceived interactivity. Eventually, the perceived interactivity had an effect on continuous usage intention of health information websites by the medium of other positively related variables.

The present study introduces a procedure to prepare and manage a high-resolution rainfall and soil moisture (SM) database in the LAMP prediction system, especially for landslide researchers. The procedure also includes converting the data into spatial resolution suitable for their interest regions following proper map projection methods. The LAMP model precipitation and SM data are quantitatively and qualitatively evaluated to identify the model prediction characteristics using the ERA5 reanalysis precipitation and observed 10m depth SM data. A detailed process of converting LAMP Weather Research and Forecasting (WRF) output data for 10m horizontal resolution is described in a step-wise manner, providing technical convenience for users to easily convert NetCDF data from the WRF model into TIF data in ArcGIS. The converted data can be viewed and downloaded via the LAMP website (http://df.ncam.kr/lamp/index.do) of the National Center for AgroMeteorology. The constructed database will contribute to monitoring and prediction of landslide risk prior to landslide response steps and should be data quality controlled by more observation data.
