This study investigated the classification and characteristics of augmented reality (AR) content of fashion brands. The AR contents of fashion brands were classified according to user participation space and content delivery method. Based on these types, eight case studies were conducted, along with a discussion of AR characteristics in terms of presence, interactivity, and immersion. The results showed that AR content could be divided into four types: offline visit-external information type, offline visit-internal experience type, online utilization-external information type, and online utilization-internal experience type. It was also found that there were differences in characteristics for each type of AR content. First, the offline visit-external information type requires various new content that can provide entertainment immersion to users. Second, the offline visit-internal experience type requires a powerful inducement for users to visit a specific space providing AR content and to participate in augmented environments. Third, the online utilization-external information type needs a series of AR content that can consistently incite users' curiosity about brands and products. Fourth, the online utilization-internal experience type needs effective content to improve users' shopping experience with the virtual fitting of fashion accessories, such as eyewear, hats, jewelry, and watches. Accordingly, fashion companies should create contents that can provide appropriate presence, interactivity, and immersion by AR type.

This study classified the current work-life balance of full-time female paid workers and tested the typology by using the 2009 Korean Time Survey. The categorization demographic and psychological characteristics of women belonging to each type were comparatively analyzed. It was found that full-time female paid workers used an average of 435.7 minutes for work, 146.4 minutes for family, 104.5 minutes for leisure, and 17.7 minutes for growth. On the basis of times used in each area of work and life, individuals were classified into family-oriented type, work-leisure parallel type, work-oriented type, work-growth parallel type, and work-family parallel type. Psychological characteristics were examined by type. The work-oriented type women experienced feelings of lack of time and fatigue the most compared with women of other types. From examining the influence that the amount of time used in each area of work and life had on psychological characteristics, it was shown that the activity time relevant to leisure influenced psychological characteristics the most. Lastly, based on the limitations of this study, future assignments are discussed.

Fault current in power system is expected to increase by demand of power capacity. Therefore, when the fault occurred, fault current was increased in the power system. Many studies have been progressed to limit the fault current. Superconducting fault current limiter (SFCL) is one of them which has been studied in worldwide. In this paper, we will analyze characteristics of a transformer-type SFCL by reclosing operation when the voltage increases. Twice opening times in the reclosing of circuit breaker were set as the 0.5 and 15 seconds, respectively. Turn's number of primary and secondary coils set 4:2 and we increased voltages from 120V to 280V for each experiment. By the current waveform, maximum fault current in second and third cycles was lowered when the voltage was increased. In the recovery waveform, recovery time was increased as the voltage was increased. The reason was that power burden of the SFCL increased when consumption power was increased, so the time to get back to SFCL took longer. We compared the characteristics of a resistive-type and transformer-type SFCL. As a result, we found that the fault current of a transformer-type was lower than resistive-type and recovery time of the SFCL was shorter. Consequently, transformer-type SFCL was more profitable for limitation of fault current and recovery time under the same condition for reclosing operation.

The college students selected by random sampling were classified into several groups by their impulse buying pattern and the psychological characteristics that cause them. Their life styles, fashion leadership, self-confidence and self-image in clothing were the subjects of comparative analysis. The results of this research can be summarized as follows. 1. The college women students could be classified into several groups by their impulse buying orientations. 2. The student life styles were different by their shopping orientations. The high shopping involved shopping type and the leisure pursuit shopping type attached great importance to material life and modern life style. The economic shopping type took the intellectual self-image seriously, and the low shopping involved type thought much of the traditional life style. 3. The high shopping involved type and the leisure pursuit shopping type were more impulse buying oriented. They showed the tendencies to the fashion innovativeness and fashion opinion leadership. But the economic shopping involved shopping type and low shopping involved shopping type showed quite different tendencies. The high shopping involved shopping type and low shopping involved shopping type were contrast in their self-confidence in shopping. The former showed the highest self-confidence and the latter showed the lowest self-confidence. 4. The high shopping involved shopping type were more extroversive, dominant, sensitive and pioneering. These psychological characteristics were supposed to contribute to their impulse buying. 5. The high shopping involved shopping type and the leisure pursuit shopping type perceived themselves as more sophisticated, modern, creative and sociable. They thought they had diverse life styles. These two groups were more impulse buying oriented, and their self-images were different from economic shopping type and low shopping involved shopping type.

This study was conducted to evaluate the growth of lactic acid bacteria and quality characteristics of Baechu kimchi prepared with four types of salt (Solar salt, Flower salt, Hanju salt, and Roasted salt) at two different concentrations (10, 15%) during storage. The quality characteristics of kimchi were examined by investigating acid production, growth of lactic acid bacteria, sensory properties, salinity, texture, and color characteristics. Baechu kimchi was fermented for 18 days at $10^{\circ}C$. The pH and total acidity did not change during storage according to type and concentration of salt. Growth of lactic acid bacteria was not affected by type of salt, whereas it was inhibited at 15% salt concentration after 9 days of fermentation. In the quantitative descriptive analysis of sensory properties, kimchi prepared with 10% salt showed significantly higher scores in term of overall acceptability (p<0.05). Meanwhile, there was no significant difference by type of salt. For texture characteristics, hardness of kimchi prepared with 10% salt was significantly higher than that with 20% salt. For color characteristics, L value (brightness) and b values (yellowness) of kimchi prepared with 10% salt increased during fermentation, whereas a value (redness) did not change by type and concentration of salt. The results of this study show that there were no considerable differences in quality characteristics of Baechu kimchi prepared with various types and concentrations of salt. However, Solar salt resulted in more favorable sensory properties and salinity of kimchi than any other types. Further, kimchi prepared with 10% salt showed significantly higher scores in terms of overall acceptability, growth of lactic acid bacteria, salinity, texture, and color characteristics.

In this study, the charactersistics of horizontal drains used to stabilize the dredged fill are investigated experimentally by doing tensile strength test, discharge capacity test, and filter clogging test. The types of the drains selected for the study are filament type (Tyre-E), embossed type(Type-P) and heat bonded cubic type with the thickness 10mm(Type-010) and 5mm(Type-05). The results of tensile strength and discharge capacity test show that the performance of drain Type-O10 was better than the other drains. This is caused by the fact that the lattice shape core of drain Type-O10 has strong rigidity and minimizes the loss of the sectional area of discharge with increased confining pressure. Analyzing the compatibility of filters by the results of the strength characteristics test and clogging test, the filter of filament type drain produced with polyester clothed polyamide performed well.

Dynamic characteristics of the bell-type structure including acoustic effects and transient dynamic problems were analyzed numerically. Natural frequencies, mode shapes and transient dynamic analysis used the finite element method with 3-D general shell element. Mode shapes and stress distributions of transient dynamic analysis were expressed by computer graphics. The method using this study was evaluated by comparision of theoretical results at reference papers(14), (15) and the experimental test using Fast Fourier Transform analyzer. Vibrational modes governing acoustic characteristics of the typical bell-type structure depended on the first flexural mode(4-0 mode) and the second flexural mode(6-0 mode). Asymmetric effects by Dangiwas, acoustic holes gave rise to beat frequencies, and the Dangjwa was found to be most effective. When impact load acted on the bell, stress concentration occured at the rim part of bell. It was found that the bell type structure should be designed thickly at the rim part in order to prevent impact load from stress concentration.
