This study examined the nutritional components and physicochemical properties of small colored potatoes and small regular potatoes as a natural health food source. To accomplish this, the general and antioxidative contents of small colored potatoes and small regular potatoes were measured. Total contents of carbohydrates, crude protein, crude lipid, and ash were 88.1%, 4.9%, 0.9%, and 6.4%, respectively. Small colored potatoes contained 76.5 kcal, while their total dietary fiber was 4.0%. Total proteins consisted of 17 different kinds of amino acids. Regarding their mineral contents, K was the most abundant mineral, followed by P, Mg, and Ca. Total phenol contents of the 70% ethanolic extracts of small colored potatoes were $48.2{\pm}1.2$ mg GAE/g. Total flavonoid contents of the 70% ethanolic extracts were $13.1{\pm}0.3$ mg RE/g. Overall, small colored potatoes had higher amounts of nutrients and physicochemical properties than small regular potatoes. The general nutrients and other antioxidant bioactive materials in small colored potatoes were also potential materials for good health food. It is expected that follow up studies of small colored potatoes through developing processed food and evaluation of their functional properties would provide useful information as a source of functional foods.

This study was conducted to provide the basic data about the health effects of pesticide exposure among farmers for agricultural health study. We analyzed 412 self-administered questionnaires collected from the male farmers who spray pesticides in Kyoung-ju area, Korea. Survey questions were about chronic symptoms, acute symptoms while pesticide spraying, pesticide intoxication accident, safety rules, protective equipments etc. The correlations among the variables related to pesticide exposure and the factors in acute pesticide poisoning and chronic symptoms of farmers were also analyzed. For chronic symptoms, the prevalence of 'tiredness and languor', 'lumbago', 'nocturia', 'shoulder pain', 'numbness', and, for acute symptoms while pesticide spraying, the experience rate of 'itching sense of skin', 'dizziness/headache', 'fatigue', 'eye glaring' were high compared with other symptoms. For 'experience of intoxication accident by pesticide in family', 7.1% of the subjects experienced the accident and the causes were pesticide spraying, food contamination by pesticide, suicide etc. Among safety rules, 'take a bath after spraying', 'change clothes after spraying' were kept relatively well, and, for protective equipments, hat, boots, mask, gloves, protective clothes(lower) were put on relatively well. The factors associated with acute pesticide poisoning were the extent of keeping safety rules, spraying time, orchard cultivation, agricultural area and spraying days per year etc. And the factors associated with chronic symptoms were acute symptoms while pesticide spraying, agricultural area, farming career, extent of keeping safety rules, extent of agricultural work and the pesticide exposure index etc. From these results, it is suggested that to reduce the health effects by pesticide exposure among farmers, the education to promote to keep safety rules and wear protective equipments, and information services should be recommended. And further studies on the long term health effects of pesticide exposure among farmers are required.

The growth characteristics and the Germanium (Ge) uptake of rice plant (Hopyungbyeo) in soil with Ge were investigated under different soil textures to obtain the basic information for agricultural utilization of Ge. This study was carried out in the Wagner pot ($15,000^{-1}a$). Ge concentration in soils such as clay loam, silt loam, loam and sandy loam for rice plant cultivation was treated at $8mg\;kg^{-1}$. The growth status of rice plant was almost similar in all soil texture, and rice yield was higher in the order of silt loam > clay loam > loam > sandy loam. In rice bran, the Ge uptakes in silt loam, clay loam, loam and sandy loam were 980, 868, 754 and $803{\mu}g\;pot^{-1}$, respectively. The Ge uptakes of brown rice and polish rice were greater in the order of silt loam > sandy loam > clay loam > loam. In silt loam, the Ge uptake rates in leaf, stem, root, rice bran and brown rice were 19.7, 2.3, 0.03, 3.1 and 0.44%, respectively. Therefore, under the given experimental condition the optimum soil texture for production of functional rice with Ge is a silt loam.

The purposes of the study were to identify satisfaction and achievement of learning by female learner's characteristics, and to suggest measures to improve quality of education in internet education programs. In order to determine the educational effectiveness associated with the characteristics of learners, this study attempted to employ two way approaches by observing the degree of achievement for learning, which represents an instructor-oriented approach, and the degree of satisfaction for education, which represents a learner-oriented approach to enhance the quality of internet education for female learners. As an approach to evaluate the educational effectiveness, the degree of achievement in learning(Tyler's classical approach), and the degree of satisfaction for education (Scriven's consumer-oriented evaluation model) were utilized. A survey form was developed by the researcher after reviewing the various tools originated from Boshier, Cross, Gagne and Choi, and distributed to a panel of judges that examined the content validity of the instrument. The sample for the study consisted of 160 female learners from three universities in Seoul and capital area, and the survey form was used to collect data for this study. The SPSS WIN program was used in analyzing the data and a series of statistical tests were conducted including frequency, percentile, t-test, ANOVA, correlation, multiple regression, and factor analysis. The statistical significance level was 0.05. The following conclusion were drawn from this study of female internet education. First, it was evident that female internet learners tend to utilize information from internet, and this can be interpreted as participants' positive attitude, and voluntary participation. Second, educational facilities and services should be improved in the future, because the level of satisfaction was low in these areas compared to curriculum and educational methodology. Third, the participating factors influenced by the level of satisfaction for education of learner characteristics were the 'formation of inter-personal relationship and willingness to change' and the 'needs for education on internet', thus appeared that both social and educational needs influenced the level of satisfaction for education. Fourth, the degree of achievement in learning was higher in the order of 1) attitude 2) function 3) knowledge, thus, attitude change was the most important in achievement of learning. Fifth, the individual background that influenced the level of achievement in learning were age and educational experience. As for the individual level of achievement for learning, the younger and more educated group were more satisfied.

Purpose - Increasing sales of PB rice products can hinder the growth of domestic brands of rice, notwithstanding that the government is promoting domestic brands of rice. This analysis evaluated the influencing relationship among the variables of PB image, product credibility, and purchase intention of consumers who have never bought PB rice, to know the factors influencing consumers' decisions to purchase PB products. Research design, data, and methodology - PB products' brand image was analyzed as the factor that has a direct effect on purchase intention. The mediation effect of credibility on PB products is also analyzed, in terms of influencing the relationship between PB products' brand image and purchase intention. The analysis is performed on consumers that have not purchased a PB product and consumers who have purchased PB products from major distributors. Data is collected through questionnaires, from 389 of responders, and the AMOS 19.0 statistics package is used as a statistical tool. Results - It is proven that brand image has direct effects on the credibility of the product, and the credibility of product has a direct effect on purchase intention. However, it is revealed that brand image does not directly affect purchase intention, but that brand image indirectly affects it through the credibility of the product. Although the customers' recognition about PB image is low, the result shows that PB products' external attributes have effects on customers' purchase intention relating to the PB product. Therefore, it is important to establish the credibility of the PB product more than other products in terms of marketing. Conclusions - The following are the implications of the study. First, in a rice brand promotion, the credibility of the product should be ensured by a uniform brand image. To ensure the credibility of a product, the RPC brand and other brands should be unified, and the unified brand image should be applied to every product. Second, the package must possess a design as well as contents that could build consumers' perception of product credibility. Products' external attributes contribute to their credibility, which leads the consumers to purchase the products, including those consumers who have never bought PB rice products. Therefore, the products' credibility and sales can be reinforced by applying information about consumers' considerations when buying the PB rice product in different colors, font sizes, and packaging designs. This study is meaningful in two ways. First, it seeks to identify an NB revitalization strategy by exploring the purchasing behavior of customers who have no experience in buying PB rice products. Second, the results of previous studies about general brands are considered and applied in this study in order to investigate the influencing relationship among different factors of PB products. However, this study is a consumer awareness investigation; therefore, its results only have limited meaning to the relationship between brand image and purchase intention.

Field validation of PBcast, an infection risk model for Phytophthora blight of pepper, was conducted through a designed field experiment in 2012 and 2013. Conduciveness of weather conditions at 26 locations in Korea in 2014-2017 was also evaluated using PBcast. The PBcast estimated daily infection risk (IR) of Phytophthora capsici based on weather and soil texture data. In the designed filed experiment, four treatments including routine sprays at 7-day intervals (RTN7), forecast-based sprays when IR reached 200 (IR200) and 224 (IR224), and no spray (CTRL) were compared in terms of disease incidence and number of sprays recommended for disease control. In 2012, IR had reached over 200 twice, but never reached 224. In 2013, IR had reached over 200 three times and once higher than 224. The RTN7 plots were sprayed 17 and 18 times in 2012 and 2013, respectively. Weather conditions throughout the country were generally conducive for Phytophthora blight and 3-4 times of fungicide sprays would have been reduced if the PBcast forecast information was adopted in the decision-making for fungicide sprays. In conclusion, the PBcast forecast would be useful to reduce fungicide applications without losing the disease control efficacy to protect pepper crop from Phytophthora blight.

Objectives: The research was aimed at analyzing the contents of university intranet for systematically execution of the healthy information provision and healthy consultation services from 2000 January to 2004 December. Methods: We have analyzed 300(28.3%) the instances of accomplished health consultation cases from the whole 1,059 instances which were the replied in a university intranet. Results: According to the contents of health consultation in ICPC code, a general symptom 91 cases(30.3%) was most, muscle-skeletal system 44 cases(14.7%), and digestive system 43 cases(14.3%) in order of cases of health counselling. The symptoms and complaint with 155 cases(51.7%) were most in the distribution of the health counselling contents by 17 charter of ICPC. The most common reason of counselling by 17 charter of ICPC were as follows; questions about the symptom and diagnosis(118 cases, 39.3%), the preventive and treatment methods(91 cases, 30.0%), and medical fee(20cases, 6.7%) in order. We mainly answer on the content of health counselling were as follows; make an offer of medical information and knowledge(48.3%), recommend visit clinic or hospital(23.7%), guide to treatment(12.7%), and so on. Conclusions: This research showed that the program of health counselling may not meet completely the high quality and adequate distribution of health counselling by the intranet in a university by content analysis. The finding suggests that health counselling by intranet in a university may be used to supplement of systemic improvement on the intranet Q/A format from current lack of essential health information and security for the quality of the health counselling.
