  • Personalized smart devices such as smartphones and smart pads are widely used. Unlike traditional feature phones, theses smart devices allow users to choose a variety of functions, which support not only daily experiences but also business operations. Actually, there exist a huge number of applications accessible by smart device users in online and mobile application markets. Users can choose apps that fit their own tastes and needs, which is impossible for conventional phone users. With the increase in app demand, the tastes and needs of app users are becoming more diverse. To meet these requirements, numerous apps with diverse functions are being released on the market, which leads to fierce competition. Unlike offline markets, online markets have a limitation in that purchasing decisions should be made without experiencing the items. Therefore, online customers rely more on item-related information that can be seen on the item page in which online markets commonly provide details about each item. Customers can feel confident about the quality of an item through the online information and decide whether to purchase it. The same is true of online app markets. To win the sales competition against other apps that perform similar functions, app developers need to focus on writing app descriptions to attract the attention of customers. If we can measure the effect of app descriptions on sales without regard to the app's price and quality, app descriptions that facilitate the sale of apps can be identified. This study intends to provide such a quantitative result for app developers who want to promote the sales of their apps. For this purpose, we collected app details including the descriptions written in Korean from one of the largest app markets in Korea, and then extracted keywords from the descriptions. Next, the impact of the keywords on sales performance was measured through our econometric model. Through this analysis, we were able to analyze the impact of each keyword itself, apart from that of the design or quality. The keywords, comprised of the attribute and evaluation of each app, are extracted by a morpheme analyzer. Our model with the keywords as its input variables was established to analyze their impact on sales performance. A regression analysis was conducted for each category in which apps are included. This analysis was required because we found the keywords, which are emphasized in app descriptions, different category-by-category. The analysis conducted not only for free apps but also for paid apps showed which keywords have more impact on sales performance for each type of app. In the analysis of paid apps in the education category, keywords such as 'search+easy' and 'words+abundant' showed higher effectiveness. In the same category, free apps whose keywords emphasize the quality of apps showed higher sales performance. One interesting fact is that keywords describing not only the app but also the need for the app have asignificant impact. Language learning apps, regardless of whether they are sold free or paid, showed higher sales performance by including the keywords 'foreign language study+important'. This result shows that motivation for the purchase affected sales. While item reviews are widely researched in online markets, item descriptions are not very actively studied. In the case of the mobile app markets, newly introduced apps may not have many item reviews because of the low quantity sold. In such cases, item descriptions can be regarded more important when customers make a decision about purchasing items. This study is the first trial to quantitatively analyze the relationship between an item description and its impact on sales performance. The results show that our research framework successfully provides a list of the most effective sales key terms with the estimates of their effectiveness. Although this study is performed for a specified type of item (i.e., mobile apps), our model can be applied to almost all of the items traded in online markets.

  • The sensory characteristics of red wine Gerbong (G), Campbell (C), Moru (M), Gerbong + Moru (70 : 30, GM), Gerbong + Campbell (70 : 30, GC) and French wine (F, Carbernet Sauvignon, 1998) were evaluated. The preferences of color, flavor, taste and total evaluation were determined by a ranking test, and the organoleptic characteristics were evaluated by a quantitative descriptive analysis (QDA) method. The mean color scores of C, GM, F, GC, M and G were 4.74, 3.94, 4.67, 3.70, 2.65 and 1.47, respectively (p<0.001). The order for the mean score for flavor was GM (4.12) = M (3.94) = C (3.76) = F (3.76) ${\geq}$ GC (3.12)>G (2.29) (p<0.01), and the order for taste was F (4.75) ${\geq}$ C (4.25) ${\geq}$ GM (3.37) = GC (3.50) ${\geq}$ G (2.75) = M (2.37) (p<0.001). The total evaluation of mean scores showed G, M, C, GM, GC and F were 237, 2.44, 4.06, 3.87, 3.64 and 4.81, respectively (p<0.001). Influences of sensory characteristics on the total evaluation, in percentages, were 69.3% for taste, 3.7% for color, and 1.5% for flavor. The influences of taste, color, and flavor in red wine were 17% for sweet, acid, bitter and salty taste, 28.9% for purple and red color, and 14.4% for grape flavor. The attributes of the purple and red colors showed a positive correlation with grape flavor, oak flavor, grape taste, and floral tastes, but a negative correlation with $SO_2$, flavor. The attribute of sweet taste showed a positive correlation with grape flavorand floral flavor, but a negative correlation with bitter and astringency tastes, according to Pearsons correlation analysis (p<0.01).

  • As a type of mass media, cartoon has been changed by political, economic, and social cultural influences. Certainly, sports cartoon also has been influenced by them. Ever since Park Ki Jung's cartoon came out, which was assumed as the first sports cartoon in Korea, sports cartoons had been used as a means of vicarious satisfaction until 1980s. Sometimes they reflected the phases of the era that struggled to overcome poverty, and adversity followed by war. Sometimes they showed people's suppressed feelings against their society. However, in modern society, the perspective of readers changes in various ways because of the influence by postmodernism. They put more weight on individualism rather than on group, they consider individual tastes very important since personal tastes and diversity has been one of significant factors. For these reasons, sport cartoons were no more what they had used to be. By 1990s, sports cartoons had attracted readers' attention again by presenting distinctive characters, and describing fancy sports skills in cartoons trying to escape from cliche story plots such as stories about rivals, competitions, winners-losers composition, and characters' diligence. Moreover, some sports cartoons contained professional contents focusing on expert sport knowledges, and deepen information of sports. From the point of cultural industries view, these tendencies are heavily affected on sportainment industry which stands out as an emerging industry recently. The ultimate purpose of sportainment industries is making a profit by providing entertainment and amusement for their readers beyond sports games. This study focused on influences that the transition of sports cartoons affects sportainment through concrete cases in context of cultural industries since 90s. The study will analyze the concept of sportainment industries, and discuss the process of sports cartoons' transition. Once sports cartoons keep trying to challenge, and make a progress with aggressive changes, it would give great influences not only to sportainment industries but also to other kinds of pop cultural industries.

  • Iatrogenic injury following dental treatments and the use of local anesthetics may cause taste disorders. The aims of this study were to investigate quantitative and qualitative changes of taste due to unilateral inferior alveolar nerve block anesthesia and further to evaluate potential effects on taste function related to anesthesia or hypoesthesia of inferior alveolar nerve, possibly occurring after dental procedure. 30 healthy volunteers in their twenties participated in this study (male to female = 1:1, mean age of $24.0{\pm}1.8$ years). Each subject received inferior alveolar nerve block anesthesia on his or her right side with 2% lidocaine HCl containing 1:100,000 epinephrine. Before and after anesthesia, electrogustometric test and chemical localized test for salty, sweet, sour and bitter tastes were performed on the eight sites in the oral cavity; right and left anterior and lateral tongue and circumvallate papilla of the tongue and soft palate. Unilateral inferior alveolar nerve anesthesia produced elevation of electrical taste threshold and reduction of intensity ratings for all 4 tastes (salty, sweet, sour and bitter) over anterior and lateral tongue and circumvallate papilla on the ipsilateral side (p<0.05). Contralateral sides exhibited decreased intensity ratings for salty and sweet taste (p<0.05) on anterior and lateral tongue while there was no significant difference in electrogustometric testing. Based on the results of this study, it is assumed that unilateral local anesthesia on inferior alveolar nerve can affect chorda tympani and glossopharyngeal nerves on the same side, leading to taste deficits. Taste intensity on the contralateral side may, in part, be deteriorated as well.

  • To obtain basic da1a on the preparation of Cudrania tricuspidata leaves tea, the quality and anti-oxidative characteristics of dried raw leaves (RT), pan-fired leaves tea (PT) and fermented leaves tea (FT) were investigated. General characteristics of RT, PT and FT, respectively, were: moisture content 18.47, 6.23 and 8.50%; crude protein content 17.77, 20.46 and 19.13%; and carbohydrate content 54.42, 62.52 and 61.96%. The crude lipid and ash contents were in the range 0.05 - 0.07% and 9.27 -10.74% respectively; the water soluble solid content was in the order FT > PT > RT and ranged from 23.10 - 37.38%; there were no significant differences in the total polyphenol content (815.24 - 835.16 mg%). Although $L^*$ values of PT (20.94) and FT (20.85) were lower than those of RT (34.71), the $a^*$ value in PT and the $b^*$ value in FT were highest. In all ethanol extracts the reducing power, electron-donating ability and superoxide dismutase (SOD)-like activity increased in a concentration-dependent manner. Furthermore, the activity in FT was higher than in PT or RT. The total free amino-acid content was higher in FT (1429.93 mg%) than RT (1108.94 mg%) or PT (833.13 mg%). The major amino acids were L-asparagine and L-valine in RT, L-cysteine and L-glutamic acid in PT and L-proline in FT. In a sensory evaluation of PT and FT, bitter and astringent tastes were decreased relative to RT, while sweet and savory tastes, flavor, color and overall acceptability were increased. These results indicate that FT bas a higher antioxidant effect and free-amino-acid content than PT, while the sensory quality of FT is similar to that of PT.

  • Hydrolytic peptides of salted and fermented anchovy sauce, and anchovy actomyosin for the development of a rapid fermentation method with conventional tastes and flavors were studied. The optimal temperatures of crude enzymes isolated from anchor, liver and viscera of squid were 55, 40$\~$45 and $45\~60^{\circ}C$, respectively. Crude enzyme isolated from anchovy was more effective on hydrolysis of anchovy actomyosin than that from squid liver and viscera. But the crude enzyme from squid liver was less effective on NaCl than that from anchovy. Three peptides occurred in anchovy actomyosin hydrolyzed with crude enzymes from anchovy and squid liver for 30 min. Their molecular weight were determined by Superdex 200 gel chromatography as 10,800, 5,800 and 2,600 dalton. When anchovy sauce was hydrolyzed with crude enzymes of anchovy, squid liver and viscera, and Protamex during 70 days, ranges of their low molecular weight of hydrolyzed peptides were 300$\~$1,000dalton detected by Sephadex G-50 and their major amino acid compositions were glutamic acid, glycine and alanine, which was related with conventional tastes. Those amino acid compositions were similar to those of anchovy sauce hydrolyzed with squid liver, In the case of Protamex treatment, hydrolyzed peptides had high levels of isoleucine and leucine, being associated with the bitter, but a low level of glutamic acid.

  • This study explored the architectural nature, the thought reflected in the place and the 'meaning-landscape' characteristic of a place, to where a retired scholar had lived. The object of the study is the Maechun-Byulup Toesu-jeong wonlim, which consists of a summer house and a garden forest. The results of the study are as following. Toesu-jeong wonlim is located at Daejeong-ri, Sannae-myeon, Namwon-si. It had been built by Maechun Park Chi-Gi in 1870 for his residence after retirement. It is a villa type pavilion and a garden forest which have Banseondaegi(伴仙臺記), Banseondae-10-yeong, Toesu-jeong(退修亭) Sangryangmun, a writing dedicated when putting up the ridge beam of a wooden house), Toesu-jeong Wonwun Byeongsoseo, hanging boards and tablets with poems written on them. In the Toesu-jeong wonlim, there are various 'meaning-landscapes' such as the Maechun-Byulup, Banseondae, Yabakdam and Simjinam together with engraved calligraphy related to the landscaping culture. It is also possible to find the remains of beautiful engraving on the stones and woods at Goksoo Yoogeo(曲水流渠) that suggest the banquets they had while discussing the elegant tastes and appreciating the landscape. The Toesu-jeong wonlim consists of the Toesu-jeong area(a pavilion), the Gwanseon-jae area(a shrine) area and the Gyejeong area(a garden with a brook) area. The pedantic 'meaning-landscape' elements, as the residence of retired scholar who spent his remaining life with elegant tastes, and the expertise of Maechun Park Chi-Gi, as a landscaping architect who built a villa and a garden forest in the motif of a Taoist hermit, can be extracted through the Banseondae-10yeong. The Banseondae-10yeong is the first Toesu-jeong poem and consisting of the Samseon-dae, Sejin-dae, Samcheong-dam, Yabak-dam, Samseo, Takgeum-dam, flat stones, caves, stone sculptures and harvest. The existing vegetation and plants in the Toesu-jeong wonlim are; natural pine forest in the rear garden, zelkova trees, wild cherry trees, apricot trees and pine trees bent to the waterfront direction. Except some ornament-species and shielding-species such as the poplars, most of current trees and vegetation keep the shape of the original Toesu-jeong wonlim landscape.

  • The purpose of this study was to investigate the recognition and satisfaction with the menu quality of food services in an immigration detention center. The survey was conducted from January 22, 2010 to April 22, 2010 by questionnaires. A survey with 265 respondents was conducted and data analyzed by the SAS Program. In analyzing leftovers, the most common was kimchi (37.61%), followed by breads (21.52%), and beans/bean curd (17.99%). The common cause for leftover were undesirable taste (31.84%), sickness or a lack of desire for eating (19.85%). In terms of cooking methods, stir-frying, broiling, and frying were highly preferred to steaming, boiling, and salting. In the analysis of preferences in the taste and satisfaction of food service, there were significant differences in hot, sour, bitter, and light tastes (p<0.05, p<0.01, p<0.001). Satisfaction was low with hot and light tastes, whereas sour and the bitter tastes showed a high degree of satisfaction. In the opinions for quality improvement, most immigrants wanted a tastier food supply (58.69%), a diverse food supply (40.54%), and clean utensils (36.68%). In the analysis of the gap between importance and performance, food taste, variety, and sanitation were recognized as poorly performed, causing major dissatisfaction with the food. The overall satisfaction score was 'average' (3 points out of 5 points) with 3.26 points. The satisfaction score showed insignificant difference depending on religions and duration of stay in Korea, but showed significant differences depending on nationality (p<0.001).

  • This study was intended to investigate the alcohol drinking characteristics, Makgeolli drinking behavior, and perception of Makgeolli focusing on the Chinese students studying in Korea. 550 copies of self-administrated questionnaire for a survey were distributed from May 2nd to June 30th, 2012, and then 461 copies were adopted for the analyses. The drinking frequency and drinking amount at a time increased as the length of stay in Korea and monthly pocket money increased, and Makgeolli was second preferred, following beer. 97.5% of the students experienced drinking Makgeolli, the drinking rate and drinking amount of Makgeolli increased with the length of stay in Korea, and they mostly drank at restaurants and bars. Common motivations for drinking Makgeolli were taste and atmosphere while drinking it, and bad taste and headache were the most common reasons for disliking Makgeolli. The awareness of commercial Makgeolli types was low, and for the price and health promoting effects of Makgeolli, 92.4% and 85.8% of the students replied positively, respectively. These results suggest that the development of high quality Makgeolli adapted to the tastes of Chinese and relieving hangover, and advertising the health benefits would promote Makgeolli consumption in Chinese market.

  • What is an appropriate length of an article in the mobile era producing new tastes of contents combining computing and mobile communication? Is it still valid to have a lengthy article as high level journalism even in the mobile era? Is there any possibility to have a short article combination to give us readability and the amount of information? This study aims to find some answers to these questions. The length of articles were controlled with a field experiment; from an article of 346 syllables(including spaces between syllables) which does not need finger scrolling on a mobile phone to articles of 633, 1033, 1368 syllables(including spaces between syllables) which frequently appear in newspapers and broadcasting news program. All the main themes were same for 4 articles which have different length. Three hundred and eighty four students viewed one of the 4 articles through mobile phone or newspaper. Each participant checked their preference and evaluated quality on the article, were asked to recall contents of the article. In newspaper group, articles with 346 or 1033 syllables were highly evaluated. Mobile group seemed to prefer articles of 346 or 633 syllables. In conclusion, we need to consider various strategies shortening the length of an article into 346 or 633 syllables as a basic format to meet the neEds of mobile era.
