Purpose: Early morning delivery markets have grown exponentially in the last few years. This study aims to verify the effects of brand experience factors and brand personality factors of Market Kurly, a representative early morning delivery brand, on brand attachment and brand loyalty. Research design, data, and methodology: For this purpose, 204 ordinary people in their 20s and 40s who have experience in using Market Kurly were surveyed. 7 hypotheses were verified by using hierarchical regression analysis. Results: Affective experience, intellectual experience, and behavioral experience among brand experience factors had a positive effect on brand attachment. Also, brand personality-self-image congruence and brand personality-human brand congruence as brand personality factors had a positive effect on brand attachment. The brand attachment was identified as an important preceding factor to explain the brand loyalty of Market Kurly. Conclusions: When applying brand experience factors to the early morning delivery service context, each brand experience factor affected brand attachment and brand loyalty. The scope of research on brand personality-self-image congruence was expanded in that it considered both brand personality-human brand congruence and brand personality-self-image congruence. This study provides academic and practical implications by revealing that brand experience factors and brand personality factors can positively affect brand attachment and brand loyalty.

Trade in service, which deals with intangible product, is distinguished from trade of goods for tangible product. The current multilateral service trade is based on GATS which includes MFN, securing the predictability as well as transparency of related service rules, specific commitment basis market access national treatment. Recently the WTO service disputes are increasing according to the frequent filing complaints against the regulation of service trade in China. The rules of GATS are not as strict as those of GATT. The commitment schedules, which were materialized between members, gets binding effect through the obligatory provisions of GATS. The GATS is inseparable relation with the Appendix of finance, of telecommunication, and of air transport, with the schedules of commitment of member states, and with the reference paper to the 4th protocol. GATS article XIV which is the general exception of GATS has a similar structure of GATT article XX. Based on the possibility of filing to the WTO, there is a need to examine whether the whole rules, regulation, and policy international trade in service of Korea perfectly macthed with the GATS. Korea with poor resources should take up the more positive attitude for the opening of international service market. According to the reciprocal aspects of concession, if Korea doesn't open a service market, the other WTO member country wouldn't allow Korea to access the their market as well as national treatment.

Fama asserted that in an efficient market, we can't make a trading rule that consistently outperforms the average stock market returns. This study aims to suggest a machine learning algorithm to improve the trading performance of an intraday short volatility strategy applying asymmetric volatility spillover effect, and analyze its trading performance improvement. Generally stock market volatility has a negative relation with stock market return and the Korean stock market volatility is influenced by the US stock market volatility. This volatility spillover effect is asymmetric. The asymmetric volatility spillover effect refers to the phenomenon that the US stock market volatility up and down differently influence the next day's volatility of the Korean stock market. We collected the S&P 500 index, VIX, KOSPI 200 index, and V-KOSPI 200 from 2008 to 2018. We found the negative relation between the S&P 500 and VIX, and the KOSPI 200 and V-KOSPI 200. We also documented the strong volatility spillover effect from the VIX to the V-KOSPI 200. Interestingly, the asymmetric volatility spillover was also found. Whereas the VIX up is fully reflected in the opening volatility of the V-KOSPI 200, the VIX down influences partially in the opening volatility and its influence lasts to the Korean market close. If the stock market is efficient, there is no reason why there exists the asymmetric volatility spillover effect. It is a counter example of the efficient market hypothesis. To utilize this type of anomalous volatility spillover pattern, we analyzed the intraday volatility selling strategy. This strategy sells short the Korean volatility market in the morning after the US stock market volatility closes down and takes no position in the volatility market after the VIX closes up. It produced profit every year between 2008 and 2018 and the percent profitable is 68%. The trading performance showed the higher average annual return of 129% relative to the benchmark average annual return of 33%. The maximum draw down, MDD, is -41%, which is lower than that of benchmark -101%. The Sharpe ratio 0.32 of SVS strategy is much greater than the Sharpe ratio 0.08 of the Benchmark strategy. The Sharpe ratio simultaneously considers return and risk and is calculated as return divided by risk. Therefore, high Sharpe ratio means high performance when comparing different strategies with different risk and return structure. Real world trading gives rise to the trading costs including brokerage cost and slippage cost. When the trading cost is considered, the performance difference between 76% and -10% average annual returns becomes clear. To improve the performance of the suggested volatility trading strategy, we used the well-known SVM algorithm. Input variables include the VIX close to close return at day t-1, the VIX open to close return at day t-1, the VK open return at day t, and output is the up and down classification of the VK open to close return at day t. The training period is from 2008 to 2014 and the testing period is from 2015 to 2018. The kernel functions are linear function, radial basis function, and polynomial function. We suggested the modified-short volatility strategy that sells the VK in the morning when the SVM output is Down and takes no position when the SVM output is Up. The trading performance was remarkably improved. The 5-year testing period trading results of the m-SVS strategy showed very high profit and low risk relative to the benchmark SVS strategy. The annual return of the m-SVS strategy is 123% and it is higher than that of SVS strategy. The risk factor, MDD, was also significantly improved from -41% to -29%.

This research was to identify the relationships between sex role attitude and the preference of fashion advertising formatted by sex role expression, and to examine the relationships among sex role attitude and sociographic variables. This research has been done for 618 university students and working group who are living in Cheongju and Seoul. For data analysis, descriptive analysis, ANOVA, and t-test were used. The results are the following: 1. In the view of the preference of fashion advertising, the stereotypical fashion advertising has more point than the androgynous fashion advertising. 2. The advertising formation preference showed a little difference significantly by sex role attitude. The group with conservative sex role preferred the stereotypical fashion advertising. The group with open-minded sex role preferred the androgynous fashion advertising. 3. Women preferred the androgynous advertising. As the aged, they preferred the stereotypical fashion advertising and have the conservative sex role. University students have more intention to buy with an androgynous fashion commercial than working group have and they have the open-minded about sex. The group subscribed the fashion magazine has more preference for androgynous fashion advertising, as they have more open-minded sex role than other group not subscribed the fashion magazine. This results imply that the androgynous formatted advertizing is still hard to get the influence of a general market promotion because most consumers have a low androgynous fashion advertizing preference. The preference of the fashion advertizing which expressed a sex role showed significant differences as social demographics, and a sex-role attitude. Therefore, the market segment and advertising strategies which are based on sex role and consumer characteristics would be very effective.
