The major purpose of this study was to develop the nutrition education contents and material through the basic data from the service provider and the consumer. And also, to find out the differences of attitude and needs between the service provider (SP breastfeeding specialist), present consumer (PC, pregnant or lactating women) and future consumer (FC, college women). There were types of questionnaires, which consisted of needs and attitudes toward child and maternal nutrition, as well as the personal characteristics of the study subjects. The subjects consisted of 113 breastfeeding specialists who served at medical related institutions, 197 pregnant or lactating women and 309 college women. The self-administered questionnaires from subjects were collected from October to November 2005 in Seoul and Kyunggi Province. The data was analysed by SPSS Win 12.0, ANOVA and Kruskal-Wallis test. The results of this study were as following: 1) The most Important determining factors on breastfeeding was 'medical specialist's support' (3.51) and the next one was 'knowledge of maternity care practice' (3.39). And the importance score of determinating factors on breastfeeding was significantly different between each group (p < 0.001). The groups of consumer (3.50 at PC and 3.59 at FC) considered the service provider (3.32) more important. The service providers considered a more effective determining factor to be 'husband and family support' and 'peer support' than the others (p <0.001). 2) To compare the effective factors of breastfeeding practices between the three groups, the service providers were more significantly considered than the otters such as 'attendance of intervention program' (p < 0.001). But the PC group considered the most effective factors wis 'mother's job after delivery'. 3) The self-evaluated score of the breastfeeding knowledge was the most high in SP; the score was significantly different between groups. The knowledge score of nutritional aspects in human milk was most highly evaluated. But maternity care practice and public acceptance marked the lower evaluation score than other issues. 4) The desirable types of educational material was mass media, and the next was printed matter such as booklets. Two kinds if consumers preferred DVD or VCR tapes than and the service provider group (p < 0.001). 5) The priority contents of nutrition service PC group wanted the information about infant care more than maternal care (p < 0.05), but FC group's priority was significantly different compared with PC group (p < 0.001). The priority of SP group pointed out the information of practical child care methods. The results showed the needs of nutrition service, education channels, and perception toward effective factors on consumer behavior changes were significantly different between each group. Thus the result of this study may suggest that consumer oriented nutrition service programs must be developed.

Objectives: This study was conducted to examine the preferences and needs of typical Korean females adults for food and nutrition information provided by the mass media. Methods: A total of 343 females (77 in their 20s, 85 in their 30s, 88 in their 40s and 93 in their 50s) residing in the Seoul/Gyeonggido area was surveyed on general characteristics, main sources of food and nutrition information and needs for sources and contents of nutrition information. Results: The survey showed that typical Korean females obtained knowledge of food and nutrition mainly through the Internet (30.4%) and broadcasting (29.0%). Typical Korean females were interested in 'dietary management for weight control' (21.9%), 'the prevention and treatment of disease' (20.0%), 'food safety' (16.8%), 'proper dietary habits' (14.6%), 'cookery' (11.8%), 'functional foods' (9.6%), 'restaurant details' (3.5%) and 'life-cycle-specific dietary guideline' (1.6%). Needs for food and nutrition program forms on TV were 'educational programs' (34.3%), 'documentaries' (20.8), 'expert lecture-style' (13.0%), 'entertainment programs' (11.9%), 'expert conversation' (11.4%), 'news-style' (4.6%) and 'public campaign advertisements' (4.0%). On the Internet, 38.6% of the respondents preferred to get information provided by food and nutrition-related institutions (38.6%) while 26.1% preferred webtoons for nutritional information. The favored forms in mobile applications were 'monitoring their diets' (29.5%), 'data-based texts information' (21.4%), 'experts feedback' (20.6%), 'communities' (15.1%) and 'games' (13.1%). The rates of the preference to obtain information from experts such as nutritionists and dietitians and doctorsor dietitian turned reporters increased markedly with older ages. Conclusions: Since the mass media is a main source of food and nutrition information for the general public, the effectiveness and accuracy of the information provided should be enhanced by taking the needs of the public into account. The quality of information should be improved by involving more nutrition experts.

I think this will be valuable reference for assuring consistency and homogeneity of clarity and managing dental radiation equipment by experimentation of dental radiation equipment permanent which based on KS C IEC 61223-3-4 standard and KS C IEC 61223-2-7. Put a dental radiation generator and experiment equipment as source and film(sensor) length within 30 em, place the step-wedge above the film(sensor). Tie up tube voltage 60 kVp, tube current 7 mA and then get an each image through CCD sensor and film by changing the exposure time as 0.12sec, 0.25sec, 0.4sec. Repeat the test 5times as a same method. Measure the concentration of each stage of film image, which gained by experiment, using photometer. And the image that gained by CCD sensor, analyze the pixel value's change by using image J, which is analyzing image program provided by NIH(National Institutes of Health). In case of film, while 0.12sec and 0.25sec show regular rising pattern of density gap as exposure time's increase, 0.4sec shows low rather than 0.12sec and 0.25sec. In case of CCD sensor density test, the result shows opposite pattern of film. This makes me think that pixels of CCD's sensor can have 0~255 value but it becomes saturation if the value is over 255. The way that getting clear reception during decreasing human's exposed radiation is one of maintaining an equipment as a best condition. So we should keeping a dental radiation equipment's condition steadily through cyclic permanent test after factor examination. Even digital equipment doesn't maintain a permanent, it can maintain a clarity by post processing of image so that hard to set it as standard of permanent test. Therefore it would be more increase the accuracy that compare a film as standard image. Thus I consider it will be an important measurement to care for dental radiation equipment and warrant homogeneity, consistency of dental image's clarity through comparing pattern which is the result from factor test against cyclic permanent test.

The objectives of this study were to investigate the antihyperglycemic and hypolipidmic effects of sea oak(Eisenia bicyclis, EB) in the diabetic state and to examine the appropriateness of formulated EB pill for the effects. The various test materials obtained from EB were included in the experimental diets with 15% fat/0.5% cholesterol and fed to streptozotocin-induced diabetic mice weighing $35.0{\pm}0.7$ g for three weeks but not in the control diet having the same composition. The test materials were EB dry powder, water and ethanol extracts, viscozyme-treated EB water extract(EB enzyme-TR) and formulated pill containing dry powders of the EB, two kinds of seaweed, black soybean, sesame, onion and garlic. BG was measured during feeding period and serum insulin, lipids and thiobarbituric acid reactive substances(TBARS) and intestinal disaccharidase activities were measured at the end of the three weeks of the feeding. BG increase was lower in the EB enzyme-TR group after 10 days of the experimental diet but lower in EB pill group after 15 days compared with the control group. Serum insulin levels were higher in the EB enzyme-TR and EB pill groups. Intestinal maltase but not sucrase activity was higher in EB enzyme-TR fed group than the control group. Serum levels of total cholesterol and triglyceride were reduced by the EB enzyme-TR and EB pill compared with the control diet. HDL-/total cholesterol was increased by all EB test materials. Serum TBARS levels were lower in the EB ethanol extract and EB pill groups than in the control group and tended to be lower in the other EB groups. It is concluded that the EB enzyme-TR is the best among the EB preparations to be utilized as a functional component for improving blood glucose and lipid profile in diabetic subjects in the future. However, the pill containing low level of the EB powder is also regarded as effective and readily usable when formulated with the several other ingredients of the proper composition.(Supported by the RIC Program of MOCIE, Korea).

Purpose: After a traffic accident, first-aid performed within the first few minutes is important for the injured in terms of survival, future health, and quality of life. Taxi drivers have more possibility of witnessing traffic accidents because they spend much time on the road. If taxi drivers are well trained and can perform first-aid in a correct manner, they will play an important role in pre-hospital emergency medical services. We investigated the effect of first-aid training on taxi drivers' willingness to perform emergency care. Methods: We provided first-aid training for 600 deluxe taxi drivers in Busan in 2012. The subjects were given a questionnaire to answer at the beginning and at the end of first-aid training. Results: 427 out of 600 deluxe taxi drivers answer our questionnaire completely. 93 out of 427 deluxe taxi drivers answered that they had first-aid training within past 3 years(21.8%). 323 taxi drivers have witnessed a traffic accident(76%). 45 out of 323 deluxe taxi drivers who witnessed a traffic accident answered that they provided first-aid to victims(14.0%). After first-aid training, taxi drivers' willingness to perform emergency care was increased compared to that before training. The failed group of taxi drivers that had same or decreased willingness after first-aid training had a low level of education than the successful group that had increased willingness after first-aid training. Conclusion: First-aid training increased taxi drivers' willingness to perform emergency care. So Taxi drivers should be encouraged more to undertake and maintain first-aid training. For more volunteering of first-aid training and improvement in the effect of first-aid training, a graded education program for taxi drivers with a low level of education should be developed, and a policy on giving credit for completing first-aid training course and for carrying out first-aid needs to be formulated.
