The object of this study was to employ effective marketing methods using SNS by determining how food-related SNS usage characteristics have influence on dine-out motivation and restaurant satisfaction and how this affects people's quality of lie. Survey respondents were men and women who have had used some kinds of food-related SNS. The survey included general characteristics of respondents, food-related SNS usage characteristics, dine-out motivation, restaurant satisfaction, and food-related quality of life. Food-related SNS usage characteristics were divided into convenience, effective time-spending, and informative; Dine-out motivation was sorted into entertainment motivation and social motivation by factor analysis. Analysis of the connections between the variables by AMOS showed that among food-related SNS usage characteristics, convenience did not have a significant influence on either entertainment or social motivation. Informative had a positive effect on entertainment motivation (p<0.05), but not on social motivation. On the other hand, effective time-spending through food-related SNS had an impact on both entertainment (p<0.001) and social (p<0.05) motivation. Moreover, the effect of dine-out motivation on restaurant satisfaction showed that entertainment motivation (p<0.05) and social motivation (p<0.01) both have significant influences on restaurant satisfaction. Also, restaurant satisfaction turned out to affect quality of life (p<0.05). As a result of this study, the usage of food-related SNS did not directly influence customers' restaurant satisfaction and quality of life; (p<0.05). As a result of this study, the usage of food-related SNS did not directly influence customers' restaurant satisfaction and quality of life; however, it had an impact on dine-out motivation and gain pleasure of dining out and help improve the quality of life in the long run; thus, it is believed that marketing strategies thorough SNS by restaurant industry are required.

Recent studies have demonstrated that smoking may be one of the most significant risk factors in the development and progression of periodontal disease. Reports have indicated that smoking causes gingival blood flow to be decreased. However, studies on the effects of smoking on gingival blood flow have yielded contradictory results. The purpose of the present study was to determine the effect of smoking on gingival blood flow. One hundred volunteers(fifty non-smokers and fifty smokers) with good general and periodontal health, aged twenties(non-smoker : 22-29 years, mean=25.36, smoker : 23-29 years, mean=26.64) were selected. Laser Doppler flowmetry (floLAB, Moor Instruments Ltd., England) was applied to measure the gingival blood flow of interdental papilla, marginal gingiva, attached gingiva and alveolar mucosa of left and right upper lateral incisors. In smokers, following an overnight abstinence from smoking, gingival blood flow was measured before smoking, immediately after smoking, 1-, 2-, 3-, 4-, 5- and 6- hour after smoking from 9 a.m. to 3:30 p.m. The difference of blood flow in each tissue of non-smokers and that of each measuring time and each tissue of smokers were statistically analyzed by one way ANOVA and Tukey test. And the difference of blood flow between smokers and nonsmokers in each tissue was statistically analyzed by t-test. The results were as follows : 1. Mean blood flow was highest in alveolar mucosa, followed by interdental papilla, attached gingiva and marginal gingiva in both smokers and nonsmokers. There was a statistically significant difference in each tissue(p<0.05) . 2. There was no consistent result between mean blood flow before smoking in smokers and that of nonsmokers in each tissue. 3. There was a statistically significant difference between gingival blood flow at measuring time point and gingival blood flow of smokers in each tissue(p<0.05). The present study suggested that smoking could alter the gingival blood flow, thus might be partly contributed to periodontal destruction.

The purpose of this study was to reveal the effects of internal characteristics, such as fashion involvement, personality characteristics, and customer orientation of fashion brand salespeople on the core sales tasks, and how the core sales tasks and internal characteristics differ depending on differences in the way salespeople are remunerated. The data were collected as a questionnaire to fashion brand salespeople in Gwangju from September to October 2020. Using 235 responses, the data were analyzed with SPSS 21.0 for frequency analysis, reliability analysis, t-test, factor analysis, and regression analysis. The research results were as follows. First, fashion involvement comprises factors such as 'fashion passion and sense'and 'fashion trend interest', and the greater the 'fashion passion and sense', the better the 'sales management'and 'customer relationship management'jobs. Second, 'esthetic openness', 'responsibility' and 'extroversion' of the big five personality characteristics have a positive impact on 'sales management' and 'customer relationship management' tasks. Third, customer orientation comprises factors such as 'customer-centric understanding'and 'gain customer trust', the greater the customer-orientation, the better the 'sales management'and 'customer relationship management'tasks. Fourth, according to the position of the salesperson, the group of professional salespeople at manager level had high responses in core sales tasks, fashion involvement, customer orientation, and characteristics such as 'agreeableness', 'esthetic openness', and 'responsibility'.

During preparation of narrow curved canals, procedural accidents such as, ledge, zipping, and transportation are frequently encountered and may lead to failure of endodontic therapy. To reduce these procedural errors and efficiently manage curved canals, various modifications in instrumentation technique and the design and flexibility of instruments have been advocated. This study compared the maintenance of the original canal curvature, cross sectional canal shape, and preparation time during instrumentation with stainless steel hand (K-Flexo) file, and nickel-titanium rotary files (Profile and Lightspeed). Thirty resin blocks with simulated curved canals of 20~25 degrees were used and divided into three groups of 10 each. In group 1, canals were instrumented using a quarter turn/pull technique with K-Flexofiles. Group 2 canals were prepared with rotary NiTi Profiles. Group 3 was prepared with rotary NiTi Lightspeed instrument. Before and after instrumentation, all canals were scanned using stereo microcope, FlexCam camera, and Photoshop 3.0 computer program. The results were as follows : 1. All groups showed some loss of canal curvature after instrumentation. Average loss of canal curvature was 8.6 degrees for K-Flexofile, 7.7 degrees for Profile, and 5.8 degrees for Lightspeed. Lightspeed exhibited significantly less curvature loss than K-Flexofile (p<0.05). 2. At the apical 1-mm level, Profile produced significantly rounder canals than Lightspeed (p<0.05). At the 3-mm level, Profile and Lightspeed exhibited significantly rounder canals than K-Flexofile (p<0.05). 3. Preparation with Lightspeed was significantly faster than Profile and K-Flexofile, and Profile was faster than K-Flexofile (p<0.05). 4. There was no significant difference in incidence of zipping between the hand K-Flexofile and rotary NiTi (Profile and Lightspeed) instruments. Most of apical canals were slightly widened near the apical foramen. As a results of this study, rotary NiTi instruments are superior to the K-Flexofile in regard to the maintenance of original canal curvature, cross-sectional shape and preparation time. But more investigations and studies should be needed to evaluate the ideal canal instrumentation.

제주 전통된장으로부터 세포외효소(protease, fibrinolytic enzyme, amylase, cellulase, lipase) 분비능이 우수한 세균을 분리한 후 16S rRNA 유전자 분석과 생리적 특성을 분석하여 균주를 확인하고자 하였다. Protease 분비능은 JR14, JR19, JR25, JR32, JR38, JR47과 JR64가 표준균주인 Bacillus subtilis KCCM12027보다 활성이 높았다. Amylase 분비능은 JR6, JR25, JR38, JR56, JR81에서 나타난 반면 표준균주인 KCCM12027에서는 나타나지 않았다. Cellulase 분비능은 JR6, JR14, JR48과 JR65가 다른 분리균주 또는 표준균주보다 높았으며, lipase 분비능은 JR14와 JR48이 높았다. 혈전용해 활성은 positive control인 plasmin의 용해 영역에 비하여 JR19가 192%로 가장 높았고, hemolysis 활성도 높았다. 혈전용해능이 있는 균주인 JR19, JR32, JR47, JR64의 배양액을 zymography한 결과, 25~75 kDa 사이에서 4~5개의 밴드가 확인되었다. 된장으로부터 분리한 균주들의 16s rRNA 유전자 염기서열을 분석한 결과 모두 Bacillus species와 99%의 상동성을 나타내었으며, 혈전용해능이 가장 우수한 JR19는 B. stratosphericus 41KF2aT와 거의 일치하였다. Bacteria strains with high activities of extracellular enzymes (protease, fibrinolytic enzyme, amylase, cellulase, and lipase) were isolated from Jeju traditional fermented soybean paste (Doenjang), and characterized by 16S rRNA gene sequence analysis and physiological properties. Protease activities were higher in JR14, JR19, JR25, JR32, JR38, JR47, and JR64 than Bacillus subtilis KCCM 12027 (standard strain). Amylase activities were shown in JR6, JR25, JR38, JR56 and JR81, while not in KCCM12027. Cellulase activities were higher in JR6, JR14, JR48, and JR65 than those of other isolated strains and KCCM 12027 whereas lipase activities were the higher in JR-14 and JR-48. Thrombolytic activity in JR19 with high hemolysis activity were 192% compared with that of plasmin as a positive control. Zymogram analysis indicated that the thrombolytic active strains had 4~5 bands in the molecular weight range of 25~75 kDa. Gene sequence analysis of rRNA revealed that the isolated stains had 99% homology with Bacillus species, and the thrombolytic active stain JR19 was B. stratosphericus 41KF2aT.

This study explores the daily life of Korean designers in New York. We use in-depth interviews within the daily lives of participants to first reveal the time structure and meaning of everyday life. In this everyday time frame, this study reveals the content and meaning of life in New York, which is especially useful for fashion majors. Participants were 11 single Korean women around 30 years old working as designers in New York. Data was collected from Manhattan, New York, from November 2013 to February 2014 through the use of in-depth interviews and participant observation. Data collected daily life information on time usage, money, and energy that is first summarized into 229 meaning units. In the following, 55 central meanings were derived from stories common to behaviors for study participants and 19 subcategories were compressed into academic language. Finally, the generalized categories are divided into six categories of study life, work life, future life, family life, leisure life and fashion life. As a result of the first study, the daily time structure consisted of customary public time and personal repeat time. Second, the customary public time categories included the studying for `Beginning to jump again to the best`, `Now working as a designer in New York`, and future life expecting `Future growing as a career woman`. Repeated personal time categories include family life: `A single life of a lonely and poor gentile`, leisure life: `Healing life that is supported by abundant advanced culture`, and fashion life: `New York fashion life coexist with harmony`. Third, work was the center of everyday life for study participants versus fashion and leisure that were central to everyday life when not working.
