The purpose of this study is to construct a substantive theory that described and explained how pregnant women are seeking information in context of pregnancy. A qualitative design based on the method of grounded theory was utilized. In-depth interviews were conducted with 16 pregnant women, selected by theoretical sampling who receiving antenatal care 3 different university hospitals. The interview data were transcribed and systematically analyzed according to the open coding, axial coding and selective coding. 'Increasing Sense of Self-Control over Pregnancy' was the core category for describing and guiding the process of seeking information during the pregnancy. To construct a theory of 'Increasing Sense of Self-Control over Pregnancy' in this study, eight hypothetical statement were generated from the relationships among the core category and the other categories, thus four patterns were derived as follows: 'Desperately Seeking', 'Actively Seeking', 'Unconcernedly Seeking', 'Resignedly Seeking'. The implications of the findings are discussed in terms of development of LIS theory in Korea, theory development of information behavior, education for LIS, and information service practice. The suggestions for further research are provided.

The microcapsules containing rosmarinic acid were prepared in this research. Rosmarinic acid is known that it is effective to care the winkles. Chitosan was used as a wall material, and glutaraldehyde was used as a crosslinking agent, and the microcapsules were prepared by the water-in-oil (W/O) emulsion method. In this method Span80 was used as an emulsifier, and mineral oil was used as a medium material. Perfectly spherical microcapsules were obtained in the size range of $0.5{\sim}0.9{\mu}m$. The effects of emulsifier concentration and stirring speed on the average particle size and distribution, and encapsulation efficiency were investigated. The release behavior of the microcapsules with different amount of the crosslinking agent and different emulsifier concentrations were also investigated.

The shut-in pressure calculated in common hydrofracturing test for vertical borehole equals generally to the minimum horizontal principal stress, so it should be considered as an essential parameter for determining the in-situ stress regime around the rock mass. It shows usually an ambiguous value in pressure-time history curves, however, because of the relationship between the behavior of hydraulic fractures and the condition of remote stress regime. In this study, a series of numerical analyses have been carried out to compare several methods for determining the shut-in pressure during hydrofracturing. The hydraulic-mechanical coupling has been applied to numerical analysis for simulating the fracture propagation by hydraulic pressure, and the different discontinuity geometry has been considered in numerical models to examine the effect of numerical element shape on fracture propagation pattern. From the numerical simulations with the four different discontinuity geometries, it was revealed that the shut-in pressure obtained from graphical methods rather than statistical method was relatively small. Consequently a care should be taken in selecting a method for determining the shut-in pressure when a stress anomaly around borehole and a fracture propagation with complicate mechanism are considered.

The purpose of this study is to investigate correlation between experience of visiting the dentist and oral symptoms with 10,701 high school seniors in the research data of the 8th juvenile online health behavior carried out in 2012. The results of this research showed that the lower academic grades, the more tooth crack they experienced, and the lower economic conditions, the more toothache they tended to experience. The main reasons they visited the dentist were because their teeth ached, tingled or throbbed with pain. Scores of oral symptoms, sex, economic conditions and the number of experience of visiting the dentist were found to have a significant correlation. In order to improve high school students' dental health continually, we need to install the school dental health room and need to systemize continuous dental health care system for high school students, along with development of various school dental health education programs, by vitalizing prevention based school dental health education.

Purpose: The purpose of this study was to investigate the factors that influenced the health-related quality of life of young-old (65-74 yr) men, old-old (75-84 yr) men, and oldest-old (85 yr or above) men in vulnerable aged received home care from public health center. Methods: The participants for this study were 318 aged Korean men living in D city. The data was collected from August to October, 2009 using structured questionnaires. Chi-square, One way ANOVA, Duncan test, Pearson's Correlation Coefficient and multiple regression with the SPSS WIN 14.0 program were used to analyze the data. Results: There were statistically significant differences among young-old, old-old, and oldest-old men regarding the health-related quality of life, health promoting behavior, IADL (Instrumental Activities of Daily Living), rehabilitation, depression, and social support. The model including variables related to physical, psychological, and social aspects of life, explained variance of the health-related quality of life of aged men differently, such as 39.6% of young-old, 35.4% of old-old, and 47.0% of oldest-old. Finally, IADL and social support were predictors in explaining the level of health-related quality of life among vulnerable old men regardless of age. Conclusion: Based on the findings of the study, nursing interventions should be developed to improve health-related quality of life of vulnerable aged men according to age differences.

Background: According to recent statistics, the breast cancer rate is growing fast in developing countries. In North West of Iran, the incidence of breast cancer after esophageal and gastric cancers has the highest rate. Previous studies have also indicated that women in this region show reluctance to do breast cancer screening. There is a great need for change to promote breast cancer screening among women. Social marketing is a discipline that uses the systematic application of commercial marketing techniques to promote the adoption of behavior by the target audience. Materials and Methods: In the present qualitative study, thirty-two women with breast cancer were interviewed about their experiences of breast cancer screening. A semi-structured interview guide was designed to elicit information specific to the 4 P's in social marketing. Results: Three main categories emerged from the analysis: price, service and promotion. Subcategories related to these main categories included factors effective in increasing and decreasing cost of screening, current and desirable features of screening services, and weakness of promotion. Conclusions: Screening programs should be designed to be of low cost, to meet patients' needs and should be provided in suitable places. Furthermore, it is essential that the cultural beliefs of society be improved through education. It seems necessary to design an executive protocol for breast cancer screening at different levels of primary health care to increase the women's willingness to undergo screening.

Purpose: Community child centers (CCCs) were introduced to provide after-school activities and care, including meal services to children from low-income families. The assistant cooks, who have the main responsibility for making and serving food at CCCs, are a major factor influencing the eating habits of children using CCCs. In this study, we tried to identify and understand who the assistant cooks are, what their job responsibilities are, and what they need in order to be able to provide children with healthy meals. Methods: Three focus group interviews were held with 17 workfare program participants who worked as assistant cooks at CCCs, and content analysis methods were applied using the NVivo 12 qualitative data analysis software. Results: The assistant cooks reflected on their perceptions of the children's health at the CCCs, their own cooking style, and their role at the CCCs. Additionally, barriers to the optimal provision of their services were pointed out, and improvements were suggested. Conclusion: The results of this study can be used as a fundamental resource for the development of tailored interventions that consider a child's unique environment to address health disparities, specifically with respect to childhood obesity.

Purpose: This study examined the influencing factors for metabolic syndrome and the annual medical expenditures of metabolic syndrome among public officials. Methods: The National Health Insurance data in 2009 were collected for 364,932 public officials and the heath examination results and annual medical expenditures were analyzed using PASW 18.0 program. Results: The prevalence of metabolic syndrome is 17.6%, and it was higher in male officials than that of females in all age groups. In men, the influencing factors for metabolic syndrome were: age, family history of stroke, cardiovascular disease, hypertension, and diabetes mellitus, smoking, alcohol consumption, exercise, and obesity. However, in women, health-related behaviors such as smoking, alcohol consumption and exercise did not affect metabolic syndrome. People who had metabolic syndrome showed significantly higher medical expenditures than those without metabolic syndrome. The odds ratios of having the highest quartile in medical expenditures were 1.372 (95% CI 1.252~1.504, p<.001) in women with metabolic syndrome and 1.213 (95% CI: 1.184~1.243, p<.001) in men. Conclusion: The results implied that health-related behaviors were associated with metabolic syndrome, and resulted in higher medical expenditures. In order not only to decrease the risk of metabolic syndrome but also reduce medical expenditures, nurses should plan health promotion strategies to educate public officials about healthy life strategies.
