A drop weight impact test was conducted in this study to analyze the mechanical and thermal properties caused by the changes in the ratio of carbon fiber reinforced plastic (CFRP) to ethylene vinyl acetate (EVA) laminations. The ratios of CFRP to EVA were changed from 10:0 (pure CFRP) to 9:1, 8:2, 6:4, and 5:5 by manufacturing five different types of samples, and at the same time, the mechanical/thermal properties were analyzed with thermo-graphic images. As the ratio of the CFRP lamination was increased, in which the energy absorbance is dispersed by the fibers, it was more likely for the brittle failure mode to occur. In the cases of Type 3 through Type 5, in which the role of the EVA sheet is more prominent because it absorbs the impact energy rather than dispersing it, a clear form of puncture failure mode was observed. Based on the above results, it was found that all the observation values decreased as the EVA lamination increased compared with the CFRP lamination. The EVA lamination was thus found to have a very important role in reducing the impact. However, the strain and temperature were inversely propositional.

This paper aims to identify the impact on self-satisfaction of shopping tendencies and purchase behaviors for luxury goods. The research was conducted by survey method using questionnaires. The subjects of this study were female consumers from 20 to years old with a high pusrchasing capability for luxury goods. Using the statistics program SPSS 21.0, factor analysis, reliability analysis, one-way ANOVA, and multiple-regression analysis were executed. The analysis results are summarized below. For shopping tendency depending on ages, pleasure pursuit tendency showed insignificant difference in 40~50s, but significant difference in 20~30s. For the self-satisfaction, the interpersonal satisfaction showed the difference by age group, which was much higher in the respondents in 30~50s than those in 20s. Individuality pursuit tendency and rational shopping tendency had impact on self-satisfaction and rational shopping tendency on interpersonal satisfaction in 20s. Pleasure pursuit tendency and rational shopping tendency had impact on self-satisfaction and interpersonal satisfaction and pleasure pursuit tendency on the economic satisfaction in 30s. Pleasure pursuit tendency had impact on self-satisfaction and economic satisfaction and rational satisfaction on interpersonal satisfaction in 40s. Pleasure pursuit tendency and rational shopping tendency had impact on self-satisfaction and interpersonal satisfaction in 50s. High quality had impact on self-satisfaction and economic satisfaction and practicality on interpersonal satisfaction in 20s. High quality had impact on self-satisfaction and interpersonal satisfaction in 30s. High quality had impact on interpersonal satisfaction in 40s. High quality had impact on all elements of self-satisfaction for the respondents in 50s, practicality had negative impact on interpersonal satisfaction.

The purpose of this study was to compare dietary self-efficacy for sodium intake reduction and dietary behaviors by eating areas. Subjects (797 males and 767 females) were classified according to perceived dietary habit levels related to sodium intake (lowest: ≤10 (n=434), low: 11~≤13 (n=471), high: 14~≤15 (n=360), highest: 16≤ (n=299)) using an online survey with a sample that was geographically representative of the population. The highest group was significantly younger and had a higher student proportion than the lowest group. Dining contexts regarding home led to a significantly higher sodium intake in the highest group, but it was eating out for the lowest group. The highest group had a significantly lower intention to reduce sodium intake compared to the lowest group. In the home cooked meals, the highest group displayed a significantly lower cooking frequency, less effort with respect to a low sodium diet and cooking habits related to sodium intake as compared to the lowest group. Also, regarding eating out and food service, the highest group exhibited significantly lower efforts and dietary behaviors to reduce sodium intake than the lowest group. The dietary score for sodium reduction behavior in the highest group was significantly lower compared to the lowest group, for home cooked meals, eating out, as well as food service. Thus, dietary guidelines and nutrition education for the reduction of sodium intake by eating areas need to be developed and provided.

PURPOSES : The purpose of this study is to investigate the fundamental behaviors such as stresses and deflections of the middle slab in a double-deck tunnel for the development of a middle slab design guide. METHODS : The middle slab has been divided into the following three different sections as according to its structural differences: the normal section, expansion joint section, and emergency passageway section. The normal section of middle slab represents the slab supported by brackets installed continuously along the longitudinal direction of tunnel lining. The expansion joint section refers to a discontinuity of middle slab due to the existence of a transverse expansion joint. The emergency passageway section has an empty rectangular space in the middle slab that acts as an exit in an emergency. The finite element analysis models of these three sections of middle slab have been developed to analyze their respective behaviors. RESULTS: The stresses and deflections of middle slab at the three different sections decrease as the slab thickness increases. The emergency passageway section yields the largest stresses and deflections, with the normal section yielding the smallest. CONCLUSIONS: The stress concentrations at the corners of the passageway rectangular space can be reduced by creating hunch areas at the corners. The stresses and deflections in the emergency passageway section can be significantly decreased by attaching beams under the middle slab in the passageway area.

In this study, we report the microstructure and the high-temperature oxidation behavior of Fe-Ni alloys by spark plasma sintering. Structural characterization is performed by scanning electron microscopy and X-ray diffraction. The oxidation behavior of Fe-Ni alloys is studied by means of a high-temperature oxidation test at 1000oC in air. The effect of Ni content of Fe-Ni alloys on the microstructure and on the oxidation characteristics is investigated in detail. In the case of Fe-2Ni and Fe-5Ni alloys, the microstructure is a ferrite (α) phase with body centered cubic (BCC) structure, and the microstructure of Fe-10Ni and Fe-20Ni alloys is considered to be a massive martensite (α’) phase with the same BCC structure as that of the ferrite phase. As the Ni content increases, the micro-Vickers hardness of the alloys also increases. It can also be seen that the oxidation resistance is improved by decreasing the thickness of the oxide film.

This study aimed to analyze the beverage usage behavior according to the food-related lifestyle in Seoul, Gyeonggi province area. Group 1, named ‘health & safety seeking’ group, consists of high percentage of women in their 40s, as well as a high percentage of high income and highly educated. Group 2, was group of ‘high interest in dietary life’, consists of a high percentage of women in their 30s, highly educated, earned 3~5 million won. Group 3, named ‘convenience seeking’ group, had a high percentage of men and of those in their 20s who earned less than 2 million won. In verifying the difference between food-related lifestyle groups in terms of their behaviors and attitudes towards the usage of beverage specialty shop, group 1 showed significantly high score in the number of visit beverage specialty shops, the intention to spend higher average expenditure per visit per person, importance of selection attributes of beverage specialty sho

The purpose of this paper is to examine the effect that Chinese tourists’ perceptions of beauty products and their friendliness toward Korean culture have on beauty tourism, particularly on Chinese tourists’ intent to purchase, re-purchase, and recommend beauty products. Between the 10th and 21st of June, 2016, a total of 277 questionnaires were distributed in Seoul, Busan, and Daegu using SPSS 21.0. Cronbach’s α was undertaken to test the reliability of the questions and an analysis of the frequency, factors, t-test, and Sobel test used in the study. Korean beauty was derived from two factors: “product favorability” and “product excellence and credibility.” Product favorability had a significant effect on the intent to purchase, as did participants’ friendliness toward Korean culture. Re-purchases and the intent to recommend beauty products were also significantly affected. In the relationship between the perception of beauty products and the intent to purchase, the study revealed partial mediation effects of the participants’ friendliness toward Korean culture on product favorability and complete mediation effects on product excellence and credibility. Friendliness toward Korean culture had partially mediated the effect that product favorability had on the intent to re-purchase and recommend. Tourists’ friendliness toward Korean culture had complete mediation on the effect that product excellence and credibility had on the intent to re-purchase and recommend. According to the Gender Equality and Family Act, the difference between buying and selling beauty depends on the difference between purchase and intentions. Friendliness toward Korean culture has become an important variable thanks to product superiority and reliability.

This study was performed to investigate the nutrition knowledge, dietary attitudes, and dietary behaviors among high school students by gender. The subjects were 275 students (127 male, 148 female) in Incheon metropolitan area. Selfadministered questionnaires consisted of general characteristics and anthropometric data, nutrition knowledge, dietary attitudes, and dietary behaviors. The average score of nutrition knowledge was significantly higher in female subjects (9.4) compared to male subjects (8.2) (p<0.01). Male subjects had a higher score for dietary attitudes than female subjects (p<0.001). Frequency of meals was significantly higher in male subjects compared to female subjects (p<0.05). Duration of meal time in male subjects was significantly higher (‘5-10 minutes’) compared to female subjects (p<0.001). Unbalanced diet was significantly higher in female subjects (66.3%) compared to male subjects (48.9%) (p<0.01). Male subjects showed significantly higher consumption frequency of ‘dairy’ (p<0.001) and ‘beans’ (p<0.001) compared to female subjects. For snack consumption, male subjects showed higher consumption frequency of ‘nuts’ (p<0.001), ‘soda’ (p<0.05), ‘fast foods’ (p<0.001), and ‘ramyeon’ (p<0.01), but lower consumption frequency of ‘biscuits and bakery’ (p<0.01) compared to female subjects. Therefore, it is necessary to develop a systemic nutrition education program for high school students by gender.

This study examined how Chinese tourists’ beauty tour preferences and attitudes toward Korean culture impacted their purchasing behaviors, repurchasing intentions, and the likelihood that they would recommend the products and services they received. Between the 10th and 21st of June, 2016, a total of 277 questionnaires were distributed in Seoul, Busan and Daegu using SPSS 21.0. On the surveys, beauty tour preferences were divided into the following categories: human service, high quality service, convenience․accessibility & cost, and facility & atmosphere. The study found that high quality service and convenience & accessibility significantly affected respondents’ purchasing intentions, with high quality service showing the higher standardized beta value. Friendliness to Korean culture also had a significant impact on beauty tour purchasing intentions. Preference for human service, high quality service, and facility & atmosphere significantly affected the purchasing intentions and the likelihood o f respondent recommendations, with higher standardized beta values shown (from high est to lowest) in the preference for facility & atmosphere, and preference for human service and high quality service respectively. Concerning perceptions of beauty products, preference for quality had a significant impact on the repurchasing intentions and intentions of respondents to make recommendations, as did the respondents’, friendliness toward Korean culture. This study suggests that, to be most effective, beauty tours should emphasize human service and facility & atmosphere, as well as high quality service. In addition, preference for beauty services or products, and friendliness to Korean culture must be considered.

The purpose of this study was to determine the health behaviors and nutritional status related to dyslipidemia in Korean middle-aged adults (between 50 and 64 years old) from the Korean National Health and Nutrition Examinations Survey data (2007~2010). A total of 4,721 subjects were analyzed in this study. The subjects were divided into three groups (normal, borderline, and dyslipidemia) according to serum lipid levels. Parameters included in this study were drinking and smoking, anthropometric parameters, blood and nutritional parameters. The latter parameter included food/nutrients intake. All data was adjusted by sex, region, education level, and age. General linear model and logistic regression model were used for statistical analysis. The dyslipidemia group was comprised of more men than women. By contrast, the borderline group was comprised of more women than men (p<0.001). No significant differences were observed for other general characteristics. There were more smokers and drinkers(drinking per time) in the dyslipidemia group (p<0.05). Anthropometric data showed significant difference, ie, height (p<0.05), weight, body mass index, waist circumference, percent body fat, and blood pressure were higher in the dyslipidemia group (p<0.001). Only blood urea nitrogen showed no significant difference among groups. The HbA1c (p<0.01), fasting blood glucose, GOT, GPT, creatinine levels were higher in the dyslipidemia group (p<0.001). So it is required for the management of obesity in dyslipidemia group. The dyslipidemia group ate less sea food (p<0.05). The nutrients intake of energy and protein, thiamin, riboflavin, niacin, calcium, phosphorus were lower in the dyslipidemia group (p<0.05). Therefore, to lower dyslipidemia prevalence rates, it is necessary to increase the intake of foods containing ω-3 fatty acids. We also suggest a meal management program and nutritional education to recognize the risk of dyslipidemia, especially for people such as the individual in the borderline and dyslipidemia study groups. Key words: dyslipidemia, Korean middle-aged adults, nutritional status, health behaviors

This study aimed to examine the health-related lifestyle habits and eating behaviors according to gender, ethnicity, and residence type of university students in Yanbian, China. Self-administered questionnaires were collected from 302 university students. Of the male students, 12.1% and 42.0% were in the underweight and overweight groups, respectively, and of the female subjects, 21.3% and 16.3%, were in those respective groups. More male than female students preferred the overweight body somatotype. In contrast, about 49.4% of female students were hoping to be underweight, and female students had more obvious difficulties with body somatotype perception, whereas their exercise frequency and time spent exercising per day were much less than those of male students. More Chinese than Korean-Chinese subjects exhibited regular eating habits, which included eating at the same time everyday and at the same frequency per day; these habits were, accompanied by generally healthier lifestyle habits regarding regularity of activity and exercise time. Self-boarding students had a significantly higher BMI (23.7±5.1 kg/m2) and were more likely to be overweight (43.5%) as compared to students who lived in a dormitory or with family. Salty taste was preferred by Chinese students more than Korean-Chinese students, and greasy taste was preferred by Korean-Chinese students as compared with Chinese students. This study found that inherent and environmental factors are related with the dietary behaviors of university students in Yanbian, China. Further studies are required to elucidate the structural elements of family life and the sociocultural factors associated with dietary behaviors in Yanbian.

The growing pace of market globalization has enabled firms to find it increasingly attractive to exploit growth opportunities abroad. To this end, predicting firms’ success and growth in foreign markets has become an important issue to international business researchers and managers. The international business literature suggests that different internal firm and foreign market specific environment factors drive internationalization of firms including firms’ structure, strategy, orientations, capabilities and nature of foreign market competition. Researchers interested in the field of international entrepreneurship have also given attention to firms’ international entrepreneurial orientation (IEO) as a potential driver of firms’ internationalization behavior, with few recent studies reporting investigations into the relationship between IEO and internationalization scope. The entrepreneurship literature suggests that variations in entrepreneurial behaviors may lead to exploitation of “new entry” (Oviatt & McDougall, 2005; Cavusgil & Knight, 2015). Within the international entrepreneurship discipline, international new entry is construed to entail identification and exploitation of new product-market opportunities abroad, or a pursuit of internationalization scope (Dai et al., 2014). Internationalization scope is defined as the process of seeking new market opportunities across multiple foreign markets, and is operationalized variously with indicators that tap the percentage of overseas revenue to total revenue, and the number of foreign countries and geographic regions from which a firm receives its sales. Thus, internationalization scope is viewed to be inherent and essential to the exhibition of an IEO, and may be driven by firms’ entrepreneurial proclivity. While a few studies have looked at how IEO impacts percentage of revenue firms obtain from foreign markets (Dai et al., 2014), little studies have studied how and when IEO drives regional expansion. This is notwithstanding the fact that traditional internationalization theory points to regional expansion as an antecedent to global expansion. Indeed, international business scholars have argued that a combination of increasing informal exporting activities, rising liberalization of regional economies, colonial bias, regional economic blocs and the emergence of middle class in many regional markets has created opportunities for firms to internationalize within neighboring geographical regions. Additionally, it has been argued that the benefits and costs of regional protection can motivate firms to pursue regionalization strategy as an antecedent or an alternative to globalization strategy. In drawing insights from earlier works, therefore, the present study focuses on the regional expansion of exporting firms in a Sub-Sahara African economy – Ghana, and examines how international entrepreneurial-oriented behaviors drive the firms’ intra-Africa expansion. African markets are noted for their diversity in national laws, cultures, geography, and infrastructural development. Particularly relevant to internationalizing African firms is the diversity and imperfection of marketing channels across African markets. An important implication for African firms, therefore, is how they can leverage their comparative advantage of handling diversity and imperfection of marketing channels in their home African market to successfully compete in overseas host markets with similar conditions. Accordingly, we further empirically examine how a firm’s ability to manage heterogeneous and imperfect marketing channels moderates the effect of IEO behaviors on regional expansion. We posit that the extent to which firms develop managerial and organizational capabilities to successfully compete in conditions of high market channel diversity and imperfection is a major contingency factor that can help explain when entrepreneurial behaviors influence regional expansion. By empirically examining these questions, this study brings new insights to IEO research by showing that IEO behaviors are differentially related to regionalization strategy depending on firms’ capability to manage heterogeneous and imperfect regional marketing channels. Specifically, findings from our study of small and medium sized firms in Ghana doing business in regional African markets show that regional expansion increases when levels of product innovation intensity, competitive aggressiveness and autonomous behavior are high and when regional channel management capability increases in magnitude. Additionally, the study provides evidence to show that increases in risking-taking behavior decrease regional expansion when regional channel management capability is high. Furthermore, the study demonstrates that although product innovation novelty and proactiveness are directly related to regional expansion their effects are cancelled out when levels of regional channel management capability are high.

The tourism industry in Hong Kong is a substantial pillar of Hong Kong’s economic development because it has been a beneficiary of tourism revenues and employment opportunities. According to the Hong Kong Tourism Board, Hong Kong accommodated 60.8 million ever-high visitors flow in 2014 (Hong Kong Tourism Commission, 2014). As three major inbound markets Mainland China, Japan, and the United States have been among the top five inbound visitors since 2003. A report of the Hong Kong Tourist Satisfaction Index (Tourist Satisfaction Index, 2014) indicated that Japanese and Korean tourists’ overall satisfaction with Hong Kong decreased from 70.11% in 2012 to 66.98% in 2014. Americans recorded the highest satisfaction level concerning experience in Hong Kong as a tourist destination, awarding it 81.8%. Moreover, the tourism industry in Hong Kong has recently relied heavily on mainland Chinese tourists as the major target group; this group comprises nearly 70% of all overnight visitors (Hong Kong Tourism Board, 2015). These three oversea markets have played an essential role towards Hong Kong tourism industry in past decade.

Charismatic public figures are often associated with personal magnetism, a captivating aura, and an ability to influence their counterparts. Over the last 25 years, the concept of charisma has gained considerable interest among social scientists, and its positive effects on performance have been reported in multiple research areas (Vercic & Vercic, 2011). Nevertheless, there exists scarce research on charisma in marketing and little is known about specific nonverbal behaviors that predict charisma (Heide, 2013). Additionally, for decades a substantial body of sales research has been focusing on identifying characteristics of sales personnel that predict performance (Bauer & Martin, 2009). Therefore, the aim of this paper is to identify nonverbal behaviors that lead to a salesperson’s charisma in a personal selling context by posing the following research question: Which aspects of body language differentiate salespersons from each other and are such differences antecedents for perceived charisma?Charismatic public figures are often associated with personal magnetism, a captivating aura, and an ability to influence their counterparts.

This study was executed to deduce the factors affecting eco-friendly behaviors and attitudes, to analyse the difference of eco-friendly behaviors and attitudes between countries, and to draw the variables affecting clothing recycling behavior. The sample comprised people from the UK, China, South Korea. The results were as follows. The four factors related to eco-friendly behaviors and the five factors related to eco-friendly attitudes were derived from the results of factor analysis. In the case of eco-friendly behaviors, four eco-friendly behavior factors showed a significant difference all according to gender and country. In the case of eco-friendly attitudes, saving of natural resources for eco-friendly life, recycling for eco-friendly life, and individual preference for eco-friendly life showed a significant according to gender, also recycling for eco-friendly life, individual preference for eco-friendly life, social awareness for eco-friendly life, and company’s awareness for eco-friendly life showed a significant difference according to country. All of the variables related to clothing recycling behaviors showed the significant difference according to gender and countries. It was verified that the stronger the behaviors or attitudes for waste recycling and environmental protection, individual preference for eco-friendly life, saving of natural resources, buying eco-friendly products, and separate collection for recycling, the more positive the action to clothing recycling. The results of this study will be helpful to establish a marketing strategy for each country and to deduce a plan to attract clothing recycling form people.

In a wide spectrum of pavement rehabilitation techniques, the application of thin asphalt overlay on existing concrete pavements have shown its ability to restore the functional capacity of the pavement system as well as maintain structural capacity. Although, prior researches stated that it does not add to the structural capacity of the existing pavement, the insulation generated by the asphalt overlay can affect the behavior of the discontinuities in the continuously reinforced concrete pavement (CRCP) system by reducing the magnitude of its movement. The investigation of crack movement behaviors of the CRCP in Chungbu Expressway was conducted in 2-phases: without overlay and with overlay. Crackmeters were installed at selected crack locations and measurements were collected. In the second phase of the investigation, crackmeters were installed at the concrete layer of the CRCP before a 2-inch asphalt overlay was applied. Results have shown that the crack movements under a thin asphalt overlay have reduced by 80% which indicates an effective insulation of the CRCP.
