Water binder ratio combine high-performance concrete shrinkage of less than 0.4 to determine the transformation to a total shrinkage of water to move outside and internal consumption of moisture due to drying shrinkage and autogenous shrinkage, and then, the relative humidity changes and strain to be approached by surface physics describe the relationship between self-desiccation and autogenous shrinkage was set. To verify the self-desiccation in the humidity shrinkage and humidity measurements performed, and the research model, Tazawa, CEB-FIP model than to let the measure and the most similar results in this study based on self-desiccation model, autogenous shrinkage didn't represent the linear shrinkage by the drying shrinkage of the external moving but exponential relationships, unlike with the nature and rapid in the early age properly describes the attributes in shrinkage could see. After this research to move moisture and to reflect the shrinkage model, temperature, moisture transfer, strain analysis by multi-physics model is very similar to the results of mock-up specimen measurements performed for this research, the value measured by the internal consumption of moisture, therefore self-desiccation and a multi-physics model considering autogenous shrinkage might be relevant.

The needs for independent 'lifelong learning' is on the rise for the individuals living in today's fast-paced society. As a result, the significance of 'information literacy' as the core requirement for lifelong learning has become widely recognized. Some countries have even established standards for information literacy at the national level, and introduced programs to improve the overall level of information literacy in the school curriculum. In Korea, various studies have been done to identify the importance of information literacy, and also there are increasing offerings of information literacy programs in regular curriculum. Based on the result of self-efficiency assessment by the students who attended the information literacy courses, this study tries to examine the effects of those programs. It consequently confirms that these curriculums resulted in improvement of the information literacy of the students, and also provide some suggestions and guidelines for the design of the curriculum for information based on the findings.

Purpose: We recruited 118 women in their early 20's to examine the relationship between sodium intake and salty taste thresholds and preference. We also examined the association of salty taste preference with sodium-related dietary behaviors and major dishes contributing to sodium intake. Methods: Daily sodium intake was estimated using a 127-item dish-frequency questionnaire. Salty taste thresholds and preference were measured using rating scales using water solution of NaCl and a self-administered questionnaire based on a Likert scale, respectively. Results: Salty taste preference showed positive correlation with daily sodium intake and sodium intake-increasing behaviors, and inverse association with sodium intake-decreasing behaviors, including salt and soy sauce use at the table, the frequency of eating out and home delivery of foods, broth consumption of soup, stew or noodle soup, the use of ready-to-serve or processed foods, fresh vegetable intake, and the accommodating attitude toward bland food. Intake of sodium-contributing dishes, including ramen, spicy soft-tofu stew, radish kimchi, and dishes containing kimchi, also showed positive association with salty taste preference. Unexpectedly, detection and recognition thresholds of salty taste showed no association with salty taste preference, sodium intake, and sodium-related dietary behaviors. Conclusion: These findings suggest that salty taste preference could reflect sodium intake of individuals rather than thresholds of saltiness, and may be used as a simple and effective proxy for usual sodium intake.

The concept of self efficacy, originally theorized by Bandura, has been applied to a wide variety of fields including education, psychology, and business. There has been steady effort to develop relevant scales to operationalize and measure self efficacy. This article reports on the results from an analysis of Kurbanoglu's ILSES (Information Literacy Self-Efficacy Scale), the only reported such scale in the area of information literacy. Over 400 university students responded to the ILSES survey consisting of 40 items grouped in six categories. The main analysis used was factor analysis. The results show high degree of internal consistency of the items included. However, the factors derived from the study differ significantly from the factors in the original study. Overall, these factors seem to reflect the heuristic nature of students' information seeking and use patterns, favoring Internet resources and instant gratification.

Relationship marketing has been dealt with as an effective strategy for customer loyalty in prior research. It seems to be essential that organizations should make efforts to develop successful relationship between the organizations and the customers. However, a customers' voluntary efforts are also needed to strengthen the relationship meaningfully. Relationships are built on the foundations of mutuality. In other words, customers' efforts are necessary for relationship development, as well as an organization's efforts. Hereby, the role of customers for the development of a relationship with an organization has been overlooked in previous research so far. This study applied the Self-Determination Theory (SDT) to explain the role of customer motivation in developing customer relationship. Thus, the author chose customers who have experienced medical service recently as survey participants. Then, this paper verified the path relationships between self-determination factors (autonomy, perceived competence, relatedness) and relational factors(shared responsibility, commitment, relationship retention). It suggested that role of customers is inevitable in developing the relationship. In conclusion, this research has several implications on relationship marketing. For service providers, they should understand that the customer's perceived self-determination can improve tangible and intangible performance in relationship development.

The increasing trend of the five violent crimes (murder, robbery, rape, violence, theft) in Korea is not independent of social and economic factors. Several social science research have discussed about this issue but most of them do not properly reflect the nature of the time-series data. Based on several time series models, we studied about the endogenous factors (time, seasonal and cycle factors) and exogenous factors (economical, social change and crime control factors) on violent crime occur in Korea. Autocorrelation were also taken into account. Through this study, we want to help to make preventive policy by explaining the cause of violent crime and predicting the future incidence of it.
