In spatial data stream management systems, it is needed appropriate load shedding algorithm because real-time input spatial data streams could exceed the limitation of main memory. However previous researches, lack regard for input ratio and spatial utilization rates of spatial data streams, or the characteristics of data source which generates data streams with spatial information efficiently, can lead to decrease the performance and accuracy of spatial data stream query. Therefore, multi-level load shedding scheme for spatial data stream management systems is proposed to increase the spatial query performance and accuracy. This proposed scheme limits overloads in relation to the input rate and the characteristics of data source first, and then, if needed, query data representing low query participation probability based on spatial utilizations are dropped relatively. Our experiments show that the proposed method could decrease load shedding frequency for previous researches by more than 11% despite query results accuracy and query performance are superior at 0.04% and 3%.

Introduction : In Korea, national attention to the workplace health promotion programs (HPP) for employees began in early 1990s. Governmental supports for the HPP and education programs have given to the employees. The purpose of this study is to find the performance degree of employees' health promoting lifestyle(HPL). Subjects and Methods : For this study, 615 employees who attended governmental educations were selected as research samples. The tool for measuring HPL used in this study was developed for Korean by In-Sook Park in 1995. It is composed of 4-point scaled 60 items and divided into 11 subcategories. The data were collected by self reporting questionnaires from June to December in 1997. Those data were analyzed percentile, mean, standard deviation, ANOVA, t-test with SAS program. Major findings are as follows; 1. The total mean score of the employees' HPL performance was 2.66. The average scores of 'harmonious relationships' category were the highest as 3.11, whereas the one of 'professional health maintenance' were the lowest as 2.02. The remains were 'sanitary life'(2.90), 'emotional support(2.85), 'regular diet'(2.84), 'self achievement'(2.78), 'healthy diet'(2.56), 'rest and sleep'(2.56), 'exercise and activity'(2.54), 'diet control'(2.53), 'self-control'(2.52). 2. The factors affecting HLP were category of industries and sex, age, marital status, education level, major, educational experience of health promotion, among personal characteristics. The employees of service industries, female, older age, married, nurse, educated for health promotion, graduated from junior college performed HLP more than the others. 3. The participation rates of employees for HPP were 12.4%, because of limited time and facilities and equipments. Recommendations; 1. The regulation for performing the health promotion programs in the industries is essential for activating industrial health promoting movement. 2. More governmental supports for educations and services for health promotion programs in the industries are needed. 3. For behavioral changes of the employees, the contents of educations have to consist of exercise and activity, rest and sleep, diet and smoking habits. 4. The evaluating studies for ready made health promotion programs in the industries are expected.

The objective of this study is to suggest a future direction for cultural programs in public libraries by literature review and the investigation of the programs in practice in Seoul Metropolitan City from various perspectives. The programs were categorized by their characteristics, such as subject, users, and managerial aspects based on the literature review. Then we investigated their rates to total number of programs in order to identify trends in years. There were two interesting points as follows: experience-centered and health education programs have been increasing in terms of the subject, and participation-oriented programs in terms of managerial aspects has also been increasing. The results led us to suggest strengthening the programs in those categories for future planning on public libraries' cultural programs.

This study was conducted to investigate pregnant women's experience about nutrition education for pregnant women in order to improve nutrition education programs. The questionnaires were distributed to 185 women with children whose age of under 24 months. About 46% of respondents participated in nutrition education for pregnant women. Major reasons for nonparticipation was 'no information(47%)' and 'lack of time(32%)'. About 40% of women attended to education operated by health centers, 34% maternity hospitals, 26% companies of formula or baby supplies. Participation rate in nutrition education showed significant differences(p<0.05) with age and household income. Women in their forties and with monthly income over three million Won showed higher rates than those of women in other groups. The subjects of education were nutrient supplements for pregnant women(21%), pregnancy complications and health(19%), abnormal symptoms of pregnancy and nutrition (18%), weight gain during pregnancy(17%), dietary guideline and directions for pregnancy (15%), relationship between nutrition of pregnant woman and baby's health(10%) in order. Teaching method which was used most frequently was lecture(35%). About 74% of women were not satisfied with the education. Nutrition management for pregnancy was the subject which pregnant women wanted to learn but not been taught enough. About 80% of women wanted more education and preferred personalized education such as personal counselling (30%), home visitation(26%), telephone(16%) and internet(15%) counselling. These results showed nutrition education for pregnant women was unhelpful for practical life. Therefore, nutrition education programs for pregnant women has to reflected pregnant women's individual needs to heighten the effectiveness of nutrition education.

This study was conducted to investigate and improve experiences regarding breastfeeding education. Questionnaires were distributed to 185 women with children 24 months of age and younger. The period of breastfeeding was about 7.2 months and showed significant differences (p<0.01) according to women's age. About 56% of the respondents participated in breastfeeding education. Women with 3 or more children showed the highest rates of participation compared to the women in other groups(p<0.05). The reason for nonparticipation showed significant differences (p<0.05) according to women's occupation. The biggest reason for nonparticipation was 'lack of time' for housewives and 'no information' for working women. The subjects of education were benefits(20%) and techniques(19%) of breastfeeding, breast care before and after delivery(15%), nutrition care for breastfeeding mothers(11%), etc. The teaching method used most frequently was lecturing(32%). Around 81% of women were not satisfied with their breastfeeding education. The most useful subject was breastfeeding techniques(59%). Thirty percent of women pointed out that 'assessing mother's milk quantity' was the subject which women wanted to learn but were not taught enough about. Around 76% of women wanted more education and preferred personalized education such as home visitation(35%) and personal counselling(27%). Desired education methods showed significant differences(p<0.05) according to women's occupations. 'Home visitation' was the most preferred method for housewives and 'personal counselling' for working women. These results showed breastfeeding education was not helpful for practical life. Therefore, breastfeeding education should reflect women's individual needs to heighten its effectiveness.

Few studies have examined the relationship between social support and stages of adoption of cancer screening. Here we investigated associations between both structural and functional aspects of social support and stages of adoption of gastric cancer screening in the general population of Korea. The study population was derived from the 2011 Korean National Cancer Screening Survey (KNCSS), an annual cross-sectional survey that uses nationally representative random sampling to investigate cancer screening rates. Data were analyzed from 3,477 randomly selected respondents aged 40-74 years. Respondents were classified according to their stage of adoption of gastric cancer screening: precontemplation (13.2%), contemplation (18.0%), action/maintenance (56.1%), relapse risk (8.5%), and relapse stage (4.1%). Respondents with larger social networks were more likely to be in the contemplation/action/maintenance, or the relapse risk/relapse stages versus the precontemplation stage (OR=1.91, 95%CI: 1.52-2.91; p for tend=0.025). Emotional and instrumental supports were not associated with any stage of adoption of gastric cancer screening. However, respondents who reported receiving sufficient informational support were more likely to be in the relapse risk/relapse stages versus the precontemplation, or the contemplation/action/maintenance stage (p for trend=0.016). Interventions involving interactions between social network members could play an important role in increasing participation in gastric cancer screening.

Background: Breast cancer is the most common cancer among women and leading cause of death worldwide, including in Turkey. High perceptions of cancer fatalism are associated with lower rates of participation in screening for breast cancer. This study was conducted to evaluate the effect of breast cancer fatalism and other factors on breast cancer awareness among nursing students in Turkey. Materials and Methods: This cross-sectional descriptive study was conducted at three universities in the Western Black Sea region. The sample was composed of 838 nursing students. Data were collected by Personal Information Form, Powe Fatalism Inventory (PFI) and Champion's Health Belief Model Scale (CHBMS). Results: Breast cancer fatalism perception of the students was at a low level. It was determined that students; seriousness perception was moderate, health motivation, BSE benefits and BSE self-efficacy perceptions were high, and BSE barriers and sensitivity perceptions were low. In addition, it was determined that students awareness of breast cancer was affected by breast cancer fatalism, class level, family history of breast cancer, knowledge on BSE, source of information on BSE, frequency of BSE performing, having breast examination by a healthcare professional within the last year and their health beliefs. Conclusions: In promoting breast cancer early diagnosis behaviour, it is recommended to evaluate fatalism perceptions and health beliefs of the students and to arrange training programs for this purpose.

The kinetics of 2-anthracenesulfonyl chloride in methanol-water, ethanol-water, acetone-water and acetonitrile-water has been studied by electroconductometric method. For media in which water has the same mole fraction, the rate was greater in protic solvent than in dipolar aprotic solvent and it was greater consistently in methanol-water than in ethanol-water over the whole range of solvent composition investigated, while the two rates in acetone-water and acetonitrile-water inverted at about 0.9 of mole fraction of water. Both m value, susceptibility of rate to the ionizing power and n value, solvent participation number in the transition state were much smaller in protic solvent. These values and the activation parameters show that solvolysis of 2-anthracenesulfonyl chloride proceeds by $ S_N2$ mechanism.

Recently rapid changes in the industrial environment require new talents in companies. Flipped learning is drawing attention as an effective teaching-learning method. The existing traditional lecture teaching-learning method have various problems that the dropout rates of the student is high and the creative problem solving ability is hindered. In the case of the IT engineering college, most of the major theoretical courses require prior learning of the prerequisite coursework subjects. Therefore, effective teaching-learning methods must be developed to improve student participation and academic achievement. This paper proposes the flipped learning model consisting of five sets that combine the flipped learning and practice to improve student motivation and self - directed learning. Also, this paper analyzes the learning effect by applying it to the algorithm lecture of computer engineering and presents problem and utilization plan according to the result.
