The purpose of this study was to identify factors of intrinsic motivation that affect regular breast cancer screening and contribute to development of a program for strategies to improve effective breast cancer screening. Subjects were residing in South Korea Gangwon-Province and were female over 40 and under 69 years of age. For the investigation, the Intrinsic Motivation Inventory (IMI) was modified to the situation of cancer screening and was used to survey 905 inhabitants. Multinominal logistic regression analyses were conducted for regular breast cancer screening (RS), one-time breast cancer screening (OS) and non-breast cancer screening (NS). For statistical analysis, IBM SPSS 20.0 was utilized. The determinant factors between RS and NS were "perceived effort and choice" and "stress and strain" - internal motivations related to regular breast cancer screening. Also, determinant factors between RS and OS are "age" and "perceived effort and choice" for internal motivation related to cancer screening. To increase regular screening, strategies that address individual perceived effort and choice are recommended.

In this paper, we investigate the determinant factors of performance of global standardization experts in their standardization activities. Standards experts of various nationalities were surveyed to assess incentives that may positively influence the performance of standards professionals. As a basis for this study, we make three main assumptions. First, incentives can be important determinant factors of performance among standards experts. Second, standardization is in the public interest, insofar as the efficiency gains resulting from standardization benefit society as a whole. Third, based on this assumption that standardization is in the public interest, we propose that performance determinants for standardization activities tend to be non-monetary in nature rather than monetary. We find that, in order to improve performance among international standards experts, a better understanding of their aspirations and needs must be gained so that appropriate incentives may be proposed to them. Our analysis reveals that the two most important determinant factors of performance are the recognition of the professional status of international standards experts, and an environment providing support systems to help them perform to their fullest potential.

The Purpose of this study was to seek determinant factors through analysis of 65 snatch skill kinematic factors of Athletics participated in 2001 Asian weightlifting competetion. The conclusion were as follows ; 1. In order to enhance snatch skill, when barbell move on knee position, One should be flex knee joint to 105-110 degree, and In pull motion, One should be move powerful extension of knee and hip joint. 2. In last pull motion, One try to make more lock out motion than extra extention motion of hip joint 3. In order to enhance snatch skill, It is inportant that elevate barbell highly by last pull motion through powerful knee extention, poweful hip flextion and One should be make lock out motion fast in the same time. 4. In order to enhance snatch skill, anterior-posterior movement width of shoulder joint should be small. 5. In order to enhance snatch skill, Hip joint should be move vertically on start and lock out phase, but In pull phase, extension motion of hip joint shoulde be performed more largely and powerfully.

In a few years, a variety of mobile devices are expected to be utilized as a necessity for business as well as personal communications. Thus it is needed to conduct a comprehensive study on the acceptance of mobile devices in the mature market like Korea. This paper develops an extended technology acceptance model by including functional attributes of cellular phone and examines the determinant factors causing accepting cellular phones. Our empirical analysis through the internet survey shows that 1) among the determinant factors, perceived usefulness, perceived enjoyment or fun, and social pressure have positive direct impacts on the intention of accepting cellular phone, and 2) functional attributes of cellular phone affect the determinant factors differently.

In Korea, breastfeeding practice has decreased since 1980's. According to the literature review, insufficient milk supply(IMS) is a major reason found by mothers for early termination of breastfeeding practice. Insufficient milk supply syndrome cannot be explained simply. IMS is a complex phenomenon that has never been adequately investigated in Korea. Using the modified IMS conceptual framework by Hill and Humenick(1989), a study was conducted at one well baby clinic located in metropolitan hospital. Approval was obtained from head of nursing service and employees ill the well baby clinic. The study sample was to restricted mothers who initiated breastfeeding and still continuously breastfeeding (n=52) and mothers who initiated breastfeeding but terminated at the time of data collection (n=39). Factor analysis suggested that Potential Determinant factors, maternal psychologic factors were : sociocultural factors, breastfeeding behaviors, breastfeeding frequency, social support, maternal education and prenatal preparation, physical and sibling support, maternal confidence, and maternal physicals which accounted for 71.12% of the variance. Using discriminant analysis those potential determinant factors predicted 72.49% of the cases accurately. These findings of research suggest that the modified IMS model is valid. But additional variables which consider Korea sociocultural factors may need to be included in future studies to determine and develop an IMS model for Korea.

As consumers' alternatives in fashion store selection increase, they select different store types to purchase different product types. Therefore, the probability of patronage mix behavior according to product type increases. Understanding consumers patronage mix behavior, finding out the determinant attributes of fashion stores for each product type are important to retailers and marketers for building a successful merchandising and marketing strategies. Most of the previous researches in store selection and patronage assume consumer behavior as single store patronage, and thus relatively little is known about patronage mix behavior. Also, little attention has been given to product characteristics as an important variable in store patronage behavior. The purposes of this study were to determine the effects of product characteristics in consumers patronage mix behavior. In this study, a theoretical model including product characteristics as an intervening variable between store attributes and patronage behavior was developed. A Questionnaire was developed and data were collected form 464 adult women living in Seoul area in Korea. Factor analysis, paired t-test, ANOVA, Duncan test and discriminant analysis were employed to analyze the data. As a result, the suggested model was partially verified. First, the product characteristic was found to have an effect on perceived importance of store attributes and on determinant attributes of stores. Consumers were found to use different evaluative criteria for store attributes when they purchase different product types. Second, the perceived importance of store attributes was determined by consumer characteristics as well as product characteristics. Third, the determinant attributes in store selection were affected not only by the perceived importance of store attributes but also by the type of product to be purchased.
