Our work empirically investigates the cultural differences of Social Networking Service (SNS) users in China, Korea and U.S. We construct a survey questionnaire from existing literature and test it for reliability, validity, and model fit. Then we collect data and validate the cultural differences of SNS users in three nations. Our results show different rankings from existing literature in cultural dimensions about three nations. In terms of masculinity, we find China > U.S. > Korea, similar to Hofstede. In individualism, we find U.S. > Korea > China, different from Hofstede (U.S. > China > Korea). In power distance, it is shown that Korea > China > U.S., different from Hofstede (China > Korea > U.S.). Uncertainty avoidance is found that U.S. > Korea > China, lowered ranking of Korea from the top among three nations in Hofstede. We find that these outcomes would be useful in updating national culture of the three nations and for future research about cultural impacts on SNS adoption.

The verified results of this study on the selected study assignments are as follows: Brand awareness of the western-style family restaurants in both study assignment One and Two is examined by showing and comparing the restaurants ranked from first to third. The ranking is based on the survey response rate only. And the familiarity of family restaurants' logos is investigated by statistical techniques such as T-test Anova, Duncan's Multiple Range Test, etc. Firstly, the analytical result of study assignment One shows that the brand awareness of the family restaurants can vary depending on how often customers use the restaurants. Secondly, the analytical result of study assignment Two shows that the familiarity and the preference of the restaurants ranked from first to third are identical each other depending on customers' sex, marital status, and income. Besides, the result shows that the brand awareness shows different rankings depending on customers' age, educational background, and occupation. Thirdly, the analytical result of study assignment Three indicates that the familiarity is different depending on customers' age, educational background, occupation, and annual income.

In this study, we attempt to examine the economic impacts of the CCS marine geological storage demonstration project in Korea using Input-Output analysis utilizing the inter-industry relation table issued in 2013. In particular, this study defines the $CO_2$ ocean storage industry and then added the inter-industry relation table and treated the $CO_2$ ocean storage industry as exogenous. In addition, this study assumed two scenarios based on the means of $CO_2$ transport, which are pipe and ship. After defining the industry and scenarios, this study investigates the production-inducing effect, value added inducing effect, and employment-inducing effect of the industries associated with the $CO_2$ ocean storage industry based on a demand-driven model. The results pertaining to the scenarios are estimated as follows: total production-inducing effects, value added inducing effects, and employment-inducing effects are calculated as 1.9044 won, 1.2487 won and 16.7224 people/billion won, respectively. In addition, compared to other industries, the indirect economic impacts of the $CO_2$ ocean storage industry are ranked high: the rankings of production-inducing effects, value added inducing effects, and employment-inducing effects are fourth, second, and fifth, respectively.

The genetic structure and diversity of 15 Chinese indigenous chicken breeds was investigated using 29 microsatellite markers. The total number of birds examined was 542, on average 36 birds per breed. A total of 277 alleles (mean number 9.55 alleles per locus, ranging from 2 to 25) was observed. All populations showed high levels of heterozygosity with the lowest estimate of 0.440 for the Gushi chickens, and the highest one of 0.644 observed for Wannan Three-yellow chickens. The global heterozygote deficit across all populations (FIT) amounted to 0.180 (p<0.001). About 16% of the total genetic variability originated from differences between breeds, with all loci contributing significantly to this differentiation. An unrooted consensus tree was constructed using the Neighbour-Joining method and pair-wise distances based on marker estimated kinships. Two main groups were found. The heavy-body type populations grouped together in one cluster while the light-body type populations formed the second cluster. The STRUCTURE software was used to assess genetic clustering of these chicken breeds. Similar to the phylogenetic analysis, the heavy-body type and light-body type populations separated first. Clustering analysis provided an accurate representation of the current genetic relations among the breeds. Remarkably similar breed rankings were obtained with all methods.

Objectives : This study introduced the healthy life-year(HeaLY), a composite indicator of disease burden, and used it to estimate the burden of major cancers in Korea. Methods : We collected data from the national death certificate database, the national health insurance claims database and the abridged life table. This data was used to create a spreadsheet and estimate the burden of major cancers by sex in terms of HeaLYs. Results : The burden of 10 major cancers for males was 2,248.97 person-year in terms of HeaLYs. Stomach cancer, liver cancer, and lung cancer were responsible for 75.2% of the burden of 10 major cancers. The disease burden of 10 major cancers for females was estimated to be 1,567.58 person-years. About two thirds of HeaLYs lost were from stomach cancer, liver cancer, lung cancer, colorectal cancer, and breast cancer. The rankings among 10 major cancers were somewhat different in terms of both HeaLYs and deaths as the HeaLY method considers both mortality and morbidity. Conclusions : Despite the limitations of the data sources, we conclude that HeaLY can aid in setting policy priorities concerning major cancers by estimating the disease burden of these cancers. Time-series analysis of the disease burden using HeaLY and DALY will elucidate the strengths and weaknesses of both methods.

Background: A unique framework for performance optimization of generation companies (GENCOs) based on health, safety, environment, and ergonomics (HSEE) indicators is presented. Methods: To rank this sector of industry, the combination of data envelopment analysis (DEA), principal component analysis (PCA), and Taguchi are used for all branches of GENCOs. These methods are applied in an integrated manner to measure the performance of GENCO. The preferred model between DEA, PCA, and Taguchi is selected based on sensitivity analysis and maximum correlation between rankings. To achieve the stated objectives, noise is introduced into input data. Results: The results show that Taguchi outperforms other methods. Moreover, a comprehensive experiment is carried out to identify the most influential factor for ranking GENCOs. Conclusion: The approach developed in this study could be used for continuous assessment and improvement of GENCO's performance in supplying energy with respect to HSEE factors. The results of such studies would help managers to have better understanding of weak and strong points in terms of HSEE factors.

The study explores the way professors working in a private university in Korea perceive the recent English-medium instruction (EMI) frenzy in Korean higher education (HE) and the way they respond to its manifestation at their institution. Working within a qualitative research paradigm (Merriam, 2009), I gathered data primarily via one-time semi-structured interviews with ten participants who have offered or are offering EMI at the time of data collection and used a qualitative data analysis method. The findings illustrate that the professors view external factors residing outside individual universities, such as the college rankings and the university evaluation parameters, as the principal drive behind the current EMI boom in Korean tertiary education. Acknowledging the importance of strengthening the international competitive edge of Korean HE in the global era, the professors perceive the EMI policy positively expecting it to be beneficial for both students and institutions. They, however, problematize the blind acceptance of EMI policy and externally forced EMI expansion movement in Korean HE, which they believe will lower the standard of the academic experience of students. Experiencing first-hand the inadequate manifestation of the EMI policy at their university, the professors claim that a systematic long-term implementation plan and context-suitable approaches should be taken at both the national and institutional level for successful future EMI implementation and expansion efforts.

Purpose: This study aimed to identify and prioritize the content needs of patients with osteoarthritis (OA) for developing self-management mobile applications. Methods: A total of 126 participants with OA were recruited from two orthopedic hospitals. They completed the self-report questionnaires after providing written informed consent. The Borich needs assessment model was used to assess the perceived level of competence and perceived level of importance regarding 21 items for self-management of OA. The collected data were weighted and ranked in order of priority. Results: The top five content items needed by OA patients were 'How to avoid excessive use of the joints' (15.03); 'Lifestyle tips on the prevention and management of arthritis' (13.69); 'Exercise types and procedures for OA' (12.54); 'Good and bad exercises for the joints' (9.80); and 'Precautions for exercise (duration, frequency, safety)' (8.88). Need rankings related to causes and treatment of OA were relatively low. Conclusion: OA patients requested self-management competencies that should be practiced in daily activities to reduce the discomfort. The results of this study have practical implications for defining the content of self-management applications for patients with OA. Based on the results, developing a self-management intervention program for OA patients using a mobile is recommended.
