  • Purpose: Even with excellent surgical outcome, recurrence of early gastric cancer (EGC) after a curative resection is not declining because the incidence of EGC is increasing. The aim of this study was to propose an appropriate treatment strategy by assessing the risk factors for recurrence of curatively resected early gastric cancer. Materials and Methods: Of 3662 patients who had undergone gastric resections for gastric cancer from 1987 to 1996, the cases of 1050 curatively resected EGC patients were reviewed retrospectively. Among those 1050 patients, 50 patients ($4.8\%$) were diagnosed as having recurrent cancer, which was confirmed by clinico-radiological examination or re-operation. The risk factors that determined the recurrence patterns were investigated by using univariate and multivariate analyses. Results: The mean time to recurrence was 30.9 months, and hematogenous recurrence was the most frequent type ($32.0\%$). Among the 50 recurred patients, peritoneal recurrence showed the shortest mean time to recurrence ($18.5\pm17.7$months). Between the recurred and the non-recurred patients, there was no statistically significant difference with respect to age, sex, operation type, tumor size, tumor location, gross appearance, or histological differentiation. However, depth of invasion (submucosal invasion) and nodal involvement were significantly different (P<0.001) between the two groups. Using logistic regression analyses, nodal involvement was the only significant risk factor for recurrence in early gastric cancer (P<0.001). The median survival after the recurrence had been diagnosed was 4 months. Conclusion: Although the prognosis for EGC patients is excellent and recurrence of EGC after a curative resection is rare, the time to recurrence and the patterns of recurrence in EGC patients were diverse and unpredictable, and the result after recurrence is dismal. Considering the impact of lymph node metastasis on recurrence of EGC, a systematic lymphadenectomy, rather than limited surgery, should be performed if lymph node involvement is confirmed pre- or intraoperatively. Also if the postoperative pathologic findings reveal lymph node involvement, adjuvant chemotherapy is recommended.

  • The purposes of this study were to understand how franchisor's influence strategies influenced franchisee's boundary spanning behaviors and how franchisor's entrepreneurship influenced franchisee's boundary spanning behaviors. This study also analyzed whether franchisor's entrepreneurship played a moderating role in the causal relationship between franchisor's influence strategies and franchisee's boundary spanning behaviors. Based on a total of 698 self-administered questionnaires obtained from franchisees(food-service unit owners or managers) in Korea, frequency analysis, exploratory factor analysis, reliability analysis and hierarchical regression analysis were conducted. The research findings showed results that firstly, promise (${\beta}$=0.292), threat (${\beta}$=-0.256), recommendation (${\beta}$=0.200), information exchange (${\beta}$=0.359), request(${\beta}$=-0.097) and legalistic plea(${\beta}$=-0.137) had a significant effect on franchisee's boundary spanning behaviors and secondly, franchisor's entrepreneurship had a significant positive effect on franchsee's boundary spanning behavior. In addition, the effects of franchisor's promise(${\beta}$=0.168) and threat(${\beta}$=-0.075) on franchisee's boundary spanning behaviors were found to be partially moderated by franchisor's entrepreneurship. Franchisees wanted franchisors to execute a high level of entrepreneurship and deliver a promise in an influence strategy. Limitations and future research directions were also discussed.

  • A study was conducted on dietitians in the Gyeonggido area to analyze the effect of purchase decision and attitude related factors regarding environmental-friendly agricultural products. The results of the factor analysis, correlation analysis and a multiple regression analysis are as follows. Many dieticians prefer environmental-friendly agricultural products, but they are reluctant to pay more money to purchase them. It was found that purchasing decision factors were 'loyalty' at 0.920, 'perceived quality' at 0.791, 'awareness' at 0.862, and 'brand' at 0.801. To conclude, the research result shows a statistically very close and positive correlation between the dieticians' attitude on environmental-friendly agricultural products and purchase decision. Other factors of quality(r=.296, p<.01), brand(r=.350, p<.01), loyalty(r=.558, p<.01), and awareness (r=.496, p<.01) acted as the most meaningful and significant variables. In short, of the dieticians surveyed in Gyeonggido province, the more favorably disposed to organic products, the more likely they are to purchase them. Accordingly, it is necessary for dieticians to be educated so that they may have greater awareness of environmental-friendly agricultural products. Furthermore, there is a need for more follow-up studies in order to gain an understanding of how to improve dieticians' attitudes on using organic products.

  • This study analyzed the effects of Employee Value Proposition (EVP) and the impotance of a job rotation system on the subjective career success. The total 379 samples were surveyed from employees engaging in domestic hotel enterprises located in Seoul using convenient sampling method. The result of this research is as followings. First, EVP has total 5 factors('career development,' 'affiliation,' 'work environment,' 'work content' and 'pay & reward') and job rotation has total 3 factors('individual capacity improvement,' 'procedural justice,' and 'career development'). Second, the results of hypotheses test using a series of multiple regression analysis indicate that EVP factors including 'career development,' 'affiliation,' 'work environment,' and 'work content' influence subjective career success. However, EVP factor of 'pay & reward' does not influence subjective career success. Similarly, EVP factors excluding 'pay & reward' affect a job rotation system. Lastly, a job rotation system positively affects subjective career success. Based on the analysis results, we could draw the importance of the non-financial reward instead of financial reward in the perception of employees' subjective career success. As a research implication, the importance of the creative organization culture was suggested in the conclusion section.

  • In recent years, Korean society has witnessed an increased interest in the observance of everyday life proprieties, building healthy families, and psychological well-being of family members. The main purpose of this research was to examine the relationships among the practice of everyday life proprieties, dynamics of family systems, and psychological well-being of Korean married couples. A self-report Questionnaire was used to collect data from married couples with a child over four-years-old who are currently residing in Seoul. 513 couples(1026 individuals) were used for the final data analysis. Statistical analyses were conducted using frequencies, percentages, means, standard deviations, Cronbach'α, Pearson correlation, paired t-test, factor analysis, and multiple regression. The findings of this study are as follows: First, the level of the practice of everyday life propriety was relatively high in both husbands and wives, and no significant gender difference was found in the level. Yet, there were some statistically significant differences in certain sub-dimensions. Wives showed a higher degree of performance in public decorum and social etiquette, whereas husbands exhibited a higher degree of performance in family decorum and communication manners. The family systems were highly dynamic, according to both husbands and wives, and there was no difference between husbands and wives. As for the sub-dimensions, the extent of communication was found to be higher among husbands than among wives. Psychological well-being was again relatively high for both husbands and wives, with husbands significantly higher than wives. Second, the findings indicate that the causal model did fit the data well, and that a myriad of background variables had direct and indirect impacts on psychological well-being, and these relationships were mediated by several variables in the sub-dimension of proprieties observance, family adaptability, and the degree of communication. The implication is that the practice of life propriety, an intervening variable, is crucial in improving psychological well-being of married couples. The findings of this research demonstrate that there are significant causal relationships among the practice of everyday life propriety, family systems dynamics, and psychological well-being. In addition, the observance of proprieties is shown to be a concept that can be used as an important predictor in the area of family resource management. Further research is needed to expand its focus on the practice of proprieties in the family resource management. More concrete and specialized family life education programs should be developed to help build healthy families. Lastly, the results indicate that proprieties education needs to be incorporated in family policies in order to promote the quality of family life.

  • This paper of descriptive-correlative design determined the effects of health perception, need of exercise and self-efficacy on the frequency of exercise among diabetic patients. A total of 86 questionnaires were retrieved from these groups of diabetic patients, who regularly visits endocrinology clinics and accomplished voluntarily the major instrument distributed from two university hospitals in A city, during June to July, 2018. The result was a significant positive relationship that existed between health perception (r=.215, p=.043) and self-efficacy (r=.440, p<.001) with frequency of exercise respectively. Regression analysis revealed that the factor affecting the frequency of exercise is self efficacy (β=.440, p<.001) which illustrated to have a significant effect in the model's explanatory power at 18.4%(F=20.836, p<.001) results. This suggests that diabetic patients with a high positive health perception increase self-efficacy, their self-efficacy will help increase the frequency of exercise if further developed. Therefore, if an intervention program is developed to improve the health perception and self-efficacy education program for diabetics, it will help improve the frequency of exercise, namely diabetes management exercise.

  • Customer participation in the service encounter plays an important role in the interaction process. In addition, customer participation is affecting the development of relationships between customer-service provider. Previous researches revealed the role of customer participation through a fragmented and cross-sectional approach, however, given the dynamics of the relationship, it is necessary to identify the role of customer participation from a longitudinal perspective. In addition, it is necessary to determine the cause of the overlap between the antecedent variables and consequent variables. This study aims to identify the relational role of customer participation by clarifying how customer participation affects relationship development from a longitudinal perspective, focusing on trust and commitment variables which are keys to relationship marketing. The related role of customer participation is analyzed through a regression analysis through long-term data. The results of the study showed that commitment(t1) directly had a positive effect on customer participation. However, trust(t1) has been shown to have a direct positive effect on the sub-dimensions of customer participation, such as personal interaction and responsible behavior. Customer participation(t2) affected by this trust(t1) and commitment(t1) again turned out to have a positive effect on trust(t3) and commitment(t3). In conclusion, although customer participation is affected by the relational variables, it can be seen that customer participation is a major factor that can improve the relational variables again through the interaction process. For this reason, a service firm can seek to develop relationships with customers by drawing and utilizing their needs to exchange information and to interact in the service encounter.
