Objective : To investigate the understanding of breast-feeding in pregnant woman and the proper way of encouraging breast-feeding. Methods : Each questionnaire included items about demographic characteristics and the understanding of breast-feeding. The questionnaires were filled up by pregnant women visiting obstetric clinics in Seoul and its vicinities, Busan, Choongjoo and Chungjoo from July 2001 to August 2001. One thousand, two hundred ninety questionnaires were analysed by Chi square tests and multiple logistic regressions. Results : The majority of pregnant women(87.4%) planned breast-feeding. Forty three percent of them had plans to breast-feed for 4-6 months. There were no differences in the level of education, the family size and the source of information about breast-feeding in planning to breast-feed (P>0.05). The main reasons for not choosing to breast-feed were returns to work(41.3%), previous failures of breast-feeding(17.4%), concerns about insufficient amount of breast milk(10.9%), breast and nipple problems(10.3%) and maternal illness(9.4%). The average score on the test of the understanding about breast-feeding was 59.7/100. The average scores on the understanding about the methods and advantages of breast-feeding were 45.3/100 and 86.1/100, respectively. The maternal status of employment, previous history of breast-feeding, the time of decision to breastfeed, person advocating breast-feeding and the understanding on the advantages of breast-feeding were significant determinant factors in planning to breast-feed(P<0.05). Conclusion : Pediatricians should take steps to make an effort to increase the breast-feeding rate and to encourage breast-feeding by timely education. Beyond the medical field, political and social supports for breast-feeding are urgently needed.

Investigations of underground cavities are required to provide useful information for the reinforcement design and monitoring of the ground subsidence areas. It is, therefore, necessary to develop integrated geophysical techniques incorporating different geophysical methods in order to accurately image and to map underground cavities in the ground subsidence areas. In this study, we conducted geophysical investigations for development of integrated geophysical techniques to detect underground cavities at the field test site in the ground subsidence area, located at Yongweol-ri, Muan-eup, Muan-gun, Jeollanam-do. We examined the applicability of geophysical methods such as electrical resistivity, electromagnetic, and microgravity to cavity detection with the aid of borehole survey results. The underground cavities are widely present within the limestone bedrock overlain by the alluvial deposits in the test site where the ground subsidences have occurred in the past. The limestone cavities are mostly filled with groundwater or clays saturated with water in the site. The cavities, thus, have low electrical resistivity and density compared to the surrounding host bedrock. The results of the study have shown that the zones of low resistivity and density correspond to the zones of the cavities identified in the boreholes at the site, and that the geophysical methods used are very effective to detect the underground cavities. Furthermore, we could map the distribution of cavities more precisely with the study results incorporated from the various geophysical methods. It is also important to notice that the microgravity method, which has rarely used in Korea, is a very promising tool to detect underground cavities.

This study analyzed the influence of the quality of medicinal food on perceived values, repurchase intention and recommendation intention. The objective of this study is to suggest the efficient operating direction for specialized medicinal food restaurants to grow as an axis of the food service industry by showing the future direction of medicinal food and establishing marketing strategies to maintain/secure customers. From June 15th to July 2nd, 2009, the survey was conducted for the customers of medicinal food restaurants, located in Seoul and Gyeonggi-do. After distributing 250 copies of questionnaire, 195 of them were collected and total 192 were used for the analysis after excluding three copies due to lack of showing sincerity. The analysis results of this study can be summarized as follows. First, the quality of medicinal food was found to have a significant influence on 'functional value(t=5.519)' while having no influence on 'social value.' Second, the 'nutritional quality' of medicinal food was analyzed as having a significant influence on 'social value(t=10.954)' and 'functional value'(t=8.237).' Third, the 'medicinal quality' of medicinal food was analyzed as having no significant influence on 'social value(t=1.191)' and 'functional value(t=0.022).' Fourth, it was found that 'social value' had a significant influence on repurchase intention(t=9.743) and recommendation intention(t=9.154). Fifth, the functional value was analyzed as having a significant influence on repurchase intention(t=7.895) and recommendation intention(t=8.143). The results of the empirical analysis shown in this study properly support the theoretical standard system to achieve successful performance and useful information necessary for systematic operation of specialized medicinal food restaurants.

The system of teaching culinary practice needs drastic modification to catch up with dietary life and education curriculum changes. To reflect such changes, it is necessary to instill a strong will and interest as well as educational environment improvement in teachers. In this sense, this study researched the teachers' stages of concerns, levels of use, innovation configuration, and intervention demands, based on the CBAM(Concerns Based Adoption Method) developed by Hord et. al. For the survey, 500 questionnaires sent by mail and 187 were analyzed by SPSS/win 10.0 program. The results are summarized as follows. 1) The teachers stages of concerns on culinary practice is assessed to be in the lowest level of perceptual stage, which indicates a state of indifference. 2) In terms of the levels of use, routine use was the highest, followed by refinement use, integrated use, research use, and reinvent use in descending order. Mechanical use posted the lowest level. Even though the stages of concern showed the beginning stage, the Level of use was relatively high. 3) About the innovation configuration, approximately 30% of the teachers were not accomodate the culinary practice referred to the 7th National Education Curriculum. 4) According to the intervention demands on culinary practice education, it was found that teachers generally wanted more interventions in every component. Among the intervention components, the highest demand was on the support for facility. Demand on the financing is the second highest. Teachers in the level of routine use demanded more information and materials supply and individual encouragement, but teachers in the level of preparation needed study opportunity for training on operation skills more.

The purpose of this study was to examine the oral health behavior and awareness of teachers in community children's centers, the state of oral health care among children in the centers and the opinions of the teachers on child oral health education in a bid to gather information required for the development of oral health education programs geared toward community children's center teachers. The subjects in this study were 178 teachers who worked in 98 community children's centers in the city of Incheon. After a survey was conducted from April 28 to June 4, 2010, the collected data were analyzed. The findings of the study were as follows: The 57.3% of the teachers investigated provided toothbrushing guidance from time to time or couldn't do it at all. As for the reason why toothbrushing guidance was scarcely conducted, the largest group cited shortage of sinks(27.5%) as the reason, and the second biggest group replied they couldn't afford to pay attention to that due to heavy workload(20.6%). The third greatest group was pressed for time(16.7%). The teachers got a mean of 3.27 in oral health behavior, and 87.7% were concerned about children's oral health. The group of teachers who ever received oral health education was significantly better at oral health behavior and showed significant more interest in oral health(p<0.01). The 97.2% of the respondents considered oral health important. Concerning the reason, they replied it was crucial for systemic health (74.2%). The 89.4% of the teachers viewed child oral health education as necessary, and 86.5% had an intention to provide oral health education for children. They hoped to receive education on the oral health control act(4.52) and the prevention of dental caries(4.40). The above-mentioned findings confirmed that in order to step up the oral health promotion of child users of local children's centers, it's necessary to provide secondhand education for them through their teachers who have a great impact on them. Therefore the development of oral health education programs that cater to local children's center teachers is required.

The study, executed with Hallasan National Park, which deserves to be a typical ecotourism destination, aims to provide basic information on park management for early establishment of ecotourism in a national park by assessing its visitors' behavior and satisfaction with a nature trail established as a series of an environmental interpretation program. The questionnaire survey was conducted at Eorimok Square in the weekday and on the weekend for two months of August and September in 2006, and finally 144 valid samples were used for the analysis. As a result of the research, it revealed that the demographic characteristics of the visitors to Hallasan National Park tended to coincide with those of the visitors to other national parks In Korea. On the whole, it showed their low recognition level of nature trails built up in national parks and less experience in using them. However, the visitors' satisfaction level and intention of re-visit, and recommendation to others were comparatively higher after actually using the nature trail at the site of Hallasan National Park, which hints at the possibility of national parks' much weightier role as the ground for ecology education and the functional expansion of the environmental interpretation-related facilities and programs. As for the attributes having effects on users' satisfaction with a nature trail, substantial aspects such as accessibility, safety, uniqueness and interest in environmental interpretation, and educational quality as well as physical facility management were revealed to have equal effects on users' satisfaction level, so there still remain a lot of pending issues over the reality of national parks in the initial stage of ecotourism staying at the level of the introduction and establishment of the facilities for environmental interpretation. This research had surveyed visitors to Hallasan National Park and limited to the nature trail only. For more systematic and practical ecological management of a national park, the in-depth understanding of the attributes affecting satisfaction of ecotourists, including nature trails and other environmental interpretation programs, and more sophisticated measuring tools are needed.

This study was conducted to provide information about the behavioral intentions to diet in adolescent females. To explain the behavior intention to diet, a conceptual framework based on the ' Social Support, Control and the Stress Process Model ' and the ' Theory of Reasoned Actio ' was used. The survey was carried out by self-questionnaires with 463 female high school and college students in Daegu. Analysis of data was done by using mean, correlation and multiple regression analysis with the SAS computer program. Subjects were divided into 3 groups-underweight, normal weight, and overweight-according to their current body size. The most powerful influencing factor related to perceived stress -that is dissatisfaction with body image- was the current figure, regardless of current body size. The fatter the current body size, the higher the score for the behavioral intention to diet. In attitude toward the behavior of dieting, the fatter the current figure, the higher the attitude score, and the belief of behavioral outcome was the main decision variable. For the score of the subjective norm, the overweight group was significantly higher than other groups. The influencing factors for the behavioral intention to diet were perceived stress and attitude toward dieting behavior, especially beliefs of behavioral outcome.

The purpose of this study was to examine the use of dentifrice among preschoolers in an attempt to provide consumers with the right information on the choice of dentifrice and toothbrush for different age groups of children. The subjects in this study were parents who raised preschoolers in Seoul and Gyeonggi Province. A self-administered survey was conducted over approximately three months from May to July 2007 to find out the state of their children's use of dentifrice. After the collected data were analyzed, the following findings were given: The greatest group (51.5%) needed parental help with toothbrushing. The biggest group of the patients (35.6%) considered it necessary for children at the age of 6 and 7 to brush their teeth with the help of their parents. As to dentifrice squeezing and parental outlook on that, the biggest group of the parents (49.4%) replied their children squeezed the dentifrice for themselves, and the greatest group (42.2%) thought that children needed parental help with dentifrice squeezing by the age of five. Regarding dentifrice swallowing and parental perception of it, the biggest group (61.9%) saw their children swallowing the dentifrice, and the greatest group (73.7%) believed that children must not swallow the dentifrice. The biggest group of those who found it okay for children to swallow the dentifrice (62.5%) thought that it would be no problem to swallow the dentifrice for child. Concerning the use of toothbrushes, the biggest group (96.7%) had their children use toothbrushes for child. The above-mentioned findings of the study showed that the children who are at the age of 3 or down should use non-fluoride containing dentifrice or just a small amount of fluoride that is as equal as the size of a pea. Children must brush their teeth under the guidance of their parents, and sustained education should be provided about that.

Objectives: The purpose of this study is to garner useful information through a comparative analysis of health behaviors and health states between the young-old and old-old elderly in a rural Korean area. Methods: We define the young-old elderly as those 65 to 74 years of age, and the old-old as those over 70. The survey was administered in October and November of 2009 at senior citizen centers in Sangju City, Kyongsangbuk-do, South Korea. The number of subjects surveyed approximated the demographics of the aged population of the administrative district of centers of 24 eup, myeon, and dong. Results: Compared with the young-old elderly, the old-old were vulnerable to population sociological characteristics. While there were many cases of contraction of diseases, only a small percentage of old-old elderly were engaged in regular exercise. In addition, the old-old elderly lagged behind the young-old in terms of physical activity, mental and oral health, hearing, and vision. Conclusions: The vulnerability of the old-old elderly in terms of physical and mental health needs to be acknowledged as various characteristics of the elderly that appears according an age group. A variety of disease prevention and health promotion programs that focus on the health behavior and status of the young-old and old-old elderly need to be developed and put into practice.
