Recently, Korean construction industry is moving from quantitative growth to qualitative growth. Among the changes in the construction industry, the competency of the project manager who represents the construction project as well as the construction company has been referred to as a factor that effects qualitative growth. This research utilized previous research analysis and expert interview in order to extract essential competency factors of a construction project manager. DEMATEL method was utilized to analyze the quantitative and objective causal relationship between the competency factors. The causal relationship of the competency factors were visualized through Digraph (directed graph) and competency areas of the project manager that requires strengthening were also suggested. Analysis result showed that the important competency categories of a project manager were Internal & External Communication, Project Management Body of Knowledge, and Inspirational Leadership. The analysis results of this research can be utilized in developing competency enhancement method for future project managers and as a basic data in developing an education program.
The purpose of this research was to investigate the impact of brand prestige on luxury marketing variables (patrons' perception of well-being, favorable inequity, affective commitment, and dedicational behaviors) in the luxury restaurant industry. Based on a thorough literature review, the clear definitions of each construct were established and theoretical causal relationships between the seven constructs were proposed (brand prestige, perception of well-being, favorable inequity, affective commitment, enhancement, advocacy, and brand consciousness). During this process, the moderating role of brand consciousness was also suggested. Integrating the proposed theoretical hypotheses, a structural model was created. This model was tested using the data collected from 527 luxury restaurant patrons in the United States. Data analysis revealed that brand prestige is a key determinant of favorable inequity and patrons' perception of well-being, thereby inducing two types of dedicational behaviors (enhancement and advocacy). More importantly, during this process, brand consciousness played a moderating role in the relationship between brand prestige and patrons' perception of well-being. Based on the data analysis results, the theoretical/practical implications were discussed.
This study investigated relationship between secondary electrons produced from single gold nanoparticle as a result of its interaction with radiation and particle size and incidence energy, provided basic data related to the dose enhancement effect based on gold nanoparticles. Monte Carlo simulation was applied by using MCNPX MC code, 50, 100, 150 kV and 6, 15 MV x-ray energy was used. In a water phantom, single gold nanoparticles that are 30, 50, 70, 90, and 110 nm in diameter were placed and the tally volume was designated at every 10 nm. Difference in electrons produced from gold nanoparticles was normalized based on absence of nanoparticle. When the X ray energy decreased and the diameter of gold particles increased, more electrons were produced. When the energy was lower, in the linear formula related to nanoparticle size and electron production, the gradient was higher. And, in comparison to the MV X-ray, at kV X-ray, significantly more electrons were produced. This study can be used as data to understand the dose enhancement effect based on gold nanoparticles, and further research related to various materials that dose enhancement including gold nanoparticles needs to be conducted.
The purpose of this study is to examine a relationship between the headquarters and the sales offices of a car manufacturing company by comparing their channel types. It examines how the level of communication and commitment of sales offices on their headquarters differently affects some mediating effects between participation and relationship performance. It also tries to find out what kind of mechanisms are needed in order to improve the relationship. Through the data analysis of a total of 200 sales offices which are directly managed stores and agency stores by a domestic car manufacturing company, the following conclusions were reached: Participation, one of the variables in bureaucratic structuring, influences all dimensions of communication. Also, it has found that communication dimensions influence commitment dimensions differently by the type of channels, and commitment dimensions influence relationship performance by the type of channels. Recently, import car makers are accelerating their moves in the domestic market, and the importance of a customer-oriented retail innovation and a relationship management in an auto manufacturing industry is increasing. This study will give an useful suggestion on how to improve a long term relationship of distributors through an enhancement of communication and commitment.

Purpose : To evaluate the relationship between the speed of enhancement of hepatic hemangiomas on gadolinium-enhanced MRI and ADC values by using various parameters, including the D, f, $D^*$ and $ADC_{fit}$ on intravoxel incoherent motion (IVIM) MR Imaging. Materials and Methods: The institutional review board approved this retrospective study. A total of 47 hepatic hemangiomas from 39 patients were included (20 men and 19 women). The hemangiomas were classified into three types according to the enhancement speed of the hepatic hemangiomas on gadolinium-enhanced dynamic T1-weighted images: rapid (Type A), intermediate (Type B), and slow (Type C) enhancement. The D, f, $D^*$ and $ADC_{fit}$ values were calculated using IVIM MR imaging. The diffusion/perfusion parameters and ADC values were compared among the three types of hemangiomas. Results: Both the $ADC_{fit}$ and D values of type C were significantly lower than those of type A (P = 0.0022, P = 0.0085). However, for the f and $D^*$, there were no significant differences among the three types. On DWI with all b values (50, 200, 500 and $800sec/mm^2$), the ADC values of type C were significantly lower than those of the type A (P < 0.012). For b values with $800sec/mm^2$, the $ADC_{800}$ values of the type C hemangiomas were significantly lower than those of type B (P = 0.0021). We found a negative correlation between hepatic hemangioma enhancement type and $ADC_{50}$ (${\rho}=-0.357$, P = 0.014), $ADC_{200}$ (${\rho}=-0.537$, P = 0.0001), $ADC_{500}$ (${\rho}=-0.614$, P = 0.0001), and $ADC_{800}$ (${\rho}=-0.607$, P = 0.0001). Therefore, four ADC values of $ADC_{50}$, $ADC_{200}$, $ADC_{500}$, and $ADC_{800}$ were decreased with decreasing enhancement speed. Conclusion: Hepatic hemangiomas had variable ADCs according to the type of enhancement, and the reduced ADCs in slowly enhancing hemangiomas may be related to the reduced pure molecular diffusion (D).
Purpose - Because creativity, which is an intangible resource embedded within the company, can offer a competitive advantage, most companies have an interest in promoting creativity among their employees and division(e.g., marketing organization). Creativity renders a sustainable competitive advantage to a firm because it is a strategic resource that is valuable, flexible, rare, and imperfectly imitable or substitutable. Although most companies broadly recognize the importance of creativity, the methods for developing creativity remain elusive. Therefore, the present study investigates how to structure incentives to motivate employees to be more creative and how to develop tools to facilitate creativity. In detail, the present study aimed to examine the relationship between the regulatory focus of marketing organizations(e.g., promotion focus vs prevention focus) and creativity of marketing organizations. In addition, the present study set out to examine the moderating role of interaction of financial reward and creative training in addition to investigating the direct relationship between creativity and regulatory focus in New Product Development(NPD) context. Research design, data, and methodology - The data used to test the hypotheses are drawn from a survey of full time NPD project members(including project manager, designer, engineer, and marketer). The present study utilized data obtained mainly from a database compiled by the Korea Investors Service-Financial Analysis System which provides comprehensive corporate and financial information on firms listed on the Korea Stock Exchange. A study population comprising 1,000 South Korean firms was obtained from this database. We selected 864 firms from the database, and the firms have experiences of new product development project. We collected a total of 162 responses, for a 18.8% response rate. After we excluded 14 questionnaire because of incomplete responses, a total of 148 questionnaire remained(final response rate: 17.1%). Working with a sample of 148 responses in South Korea, hierarchical moderated regression is employed to test research hypotheses(
The relationship between promotion focus and creativity of marketing organization,
The relationship between prevention focus and creativity of marketing organization,
The moderating effect of joint influences(interaction between financial rewards and creativity training) on the relationship between promotion focus creativity of marketing organization,
The moderating effect of joint influences(interaction between financial rewards and creativity training) on the relationship between prevention focus creativity of marketing organization). SPSS 18.0 and AMOS software were used in the data analysis. Results - The empirical study confirmed that promotion focus of marketing organization is positively related to creativity of marketing organization. Also, prevention focus of marketing organization is positively affected to creativity of marketing organization. In addition, the interaction between financial rewards and creativity training moderated the relationship between regularity focus(e.g.), promotion focus vs prevention focus) and creativity of marketing organization. These results suggest that managers can improve the performances of their creative efforts by providing the use of financial rewards and creativity training in combination. Conclusion - Based on results of this study that examine the effects of regulatory focused creative efforts on creativity of marketing organization, promotion focus is helpful with marketing organizations to enhance their service innovation and performance. Prevention focused organization should allow monetary rewards and creativity training to increase their creativity for innovation of new products.

This study examined the relationship between professional self-concept, interpersonal relationship, coping, and clinical practice satisfaction of nursing college students. This was a descriptive study. The survey participants were 355 students in M city and I city. The data were collected from May 29 to June 16, 2017 and self-report questionnaires, including the Professional Self-concept Scale, Interpersonal Relationship Scale, Coping Scale, and Clinical Practice Satisfaction Scale. The data were analyzed by descriptive statistics, independent-samples t-test, ANOVA, and stepwise multiple regression. Professional self-concept showed significant differences according to religion, income, and school records. Interpersonal relationships showed significant differences according to gender, income, and school records. Coping showed significant differences according to the school records. Professional self-concept had a statistically positive correlation with interpersonal relationship, clinical practice satisfaction, and approach coping. Stepwise multiple regression analysis showed that the predictor of professional self-concept was interpersonal relationships, approach coping, religion, school records, and avoidant coping, which accounted for 45.2% of the variance. These results highlight the need for enhancement programs of nursing college students' professional self-concept that consider their interpersonal relationships, coping, religion, and school records.
Medical communication has the effect of increasing the patient's medical treatment satisfaction and medical facility revisit rate through better understanding of the patient, and decreasing the medical law suit rate. One of the methods to enhance medical communication is through doctor coaching. Doctor coaching is a series of coaching procedure that helps the doctors have a better understanding with the patients by enhancing the communication skills of the doctors. The current study analyzed the effect 'coach and coatee's relationship', 'coaching per se', and 'coaching activity' have on coaching satisfaction. As the result, 'coaching activity' related to the coaching program showed the most influence on the coaching satisfaction On the other hand, 'coach and coatee's relationship' and 'coaching per se' did not show any significant influence while 'coach and coatees relationship' even showed negative correlations. Such result gained agreement amongst the doctors about the medical communication enhancement and necessity of doctor coaching and it also implies that intensifying the coaching qualifications and professionalism is necessary for the doctor coaching model. The coach should not only have knowledge regarding the doctor(medical??) communication, but also should endeavor to obtain understanding and knowledge about coaching strategies.
This study examined how walking moderates the influence of depression on quality of life in elderly. Data of the study were analysed using the sixth Korean National Health and Nutrition Examination Survey (KNHANES V-2, 2014). The subjects were elderly aged 65 years or more and the number of the sample was 1,263. Using hierarchial regression analysis, walking as a moderator of the depression and quality of life relationship was examined. Quality of life for elderly showed significant differences according to sex(t=8.26, p<.001), age(t=5.19, p<.001), number of chronic disease(F=37.88, p<.001), depression(t=9.62, p<.001) and walking per week (t=47.36, p<.001). Walking moderated the relationship between depression and quality of life in elderly. Based on these findings, the enhancement of walking in depressed elderly is recommended to promote the quality of life.

Objectives: The purpose of this study was to find out the relationship between academic burn out and the quality of life of college students of health and medical science, and to examine the mediating effects of self-efficacy on the relationship between them. Methods: The data of 379 college students of health and medical science in the Department of Korean Medicine and Nursing located in A and D cities were collected from March to July 2018, and were analyzed using SPSS 24.0 Statistics Program. Results: There was no mediating effect of self-efficacy on the Physical Component Score(PCS), which indicates the physical health index of quality of life in relation to academic exhaustion and quality of life of university students. However, the Mental Component Score(MCS), which indicates the mental health index, had a significant effect on the parameter of self-efficacy (β = .382, p <.001). Although the β value for the school exhaustion and MCS decreased from -.382 to -.209, the effect remains significant (β=-.209, p<.001). Conclusions: It is considered that the development and the application of a self-efficacy enhancement program is necessary to improve of self-efficacy and reduce academic burn out of college students of health and medical science.
