Results obtained from this research showed that the anaerobic contact process was applicable to pear waste with COD removal efficiencies of up to $95\%$ depending on conditions, provided ammonium and phosphate salts were added as well as other nutrients, present in the commercial fertilizer, Milorganite or in yeast extract. These latter materials were required in minimum concentrations of 5 and 1.5 g/L, respectively, in the feed independent of HRT and volatile solids loading rate, with part of the effect due to the mineral fraction. Digestion was satisfactory over the whole range of volatile solids loading rates and liquid retention time of 30 to 0.5 days tested, although treatment efficiency dropped off noticeably between 1 and 0.5 day liquid retention time because of poorer flocculation and separation of anaerobic bacteria. Settling of anaerobic bacteria including methane producing bacteria was related to settling of mixed liquor suspended solids only at 1 to 5 days liquid retention times, at other liquid retention times anaerobic microorganism settled markedly less efficiently than mixed liquor suspended solids. Further studies are being made to provide information of practical and basic interest. Data on the composition of the active fraction of yeast extract might solve many practical nutrient problems encountered with the anaerobic contact process and improve its economics. Further improvement in the flocculation and settling of anaerobic bacteria as well as other bacteria would improve overall performance and allow the use of shorter liquid retention times with dilute waste. Knowledge about the numbers of methane formers present would allow a degree of understanding and control of the process not presently attainable.

Purpose: The purpose of this study was to develop a smartphone application and evaluate it's effectiveness and usability for promoting bone health in Korean young adult women. Methods: A smartphone application was developed covering exercise, nutrition, and health habits related to bone health. A pilot testing was conducted using a one-group pre/posttest design. A total of 22 female college students with low bone mass participated in the 8-week use of a pilot testing. Results: The "Strong bone Fit body (SbFb)" application was developed using Android platform. In the pilot testing, bone mineral density, serum CTX, and 25 (OH)Vit.D were significantly decreased. There is no significant change in serum osteocalcin and calcium. Serum phosphorus concentration, nutrient intakes (fiber, VitB6, and pantotenic acid), and all bone composition profiles were significantly increased. Bone-health knowledge was significantly increased but no change in health belief and self-efficacy. Conclusion: The results of this pilot testing suggest the effectiveness of the SbFb application to enhance and promote self-managing abilities for bone health. It can provide continuous feedback and high-quality bone health information. However, some contents and working methods of the application need to be modified and its effectiveness on bone health requires further investigations.
This study is proposed to research the rural clothing, dietary and housing style of living in order to adapt a basis which is supposed to improve the quality of rural life. The sample in this research comes from Daehang 1 Li, Bubuk Myun, Miryang Gun, Kyungnam, and the results are as following; Generally rural housewives are unconcerned with fashion or its information, instead, they care for the casual wear which represents economic and active life style. Because of their financial problems, inpurchasing, they spend only a small money without plan. When they launder Clothes, they use washing bat and pannel which is easy to break fabrics, and they ineffectively use to dry it by hands twisting. The total food intake per person in a day is 1170.6gram, and all nutrients intakes except fat and calcium exceed the recommended dietary allowances. But 90.3% of the food intakes are plant food, and the average food items taken per day per househod is 11.9items which are not so various, which represents the shortage of the nutrient quality. Both the nutrition knowledge score and the food habit score are very low. Therefore, in order to enhance the quality of clothing and diet in rural life, they need to learn clothing and nutrition management for their enlightment. The most comprehensive type of farmhouse site plan take the shape of ㄱ and ㄴ, and for the most part main building is the floor plan which includes 3-4 spans in front of the change from the type of traditional house, throught the revised one, to the type of newly built house. In main building of the farmhouse, kitchen, Kunbang and Chakunbang are extended to their real space, and both utility and the bathroom are added to build, and Malu is transformed into the living space.
A significant proportion of the African continent is conducive for animal agricultural production, due to its historical experience and available resources to accommodate and nurture various indigenous and exotic animal species and breeds. With food security being a global challenge, animal products can play an important role as nutrient dense food sources in human diets, particularly in Africa. However, this does not seem to reach its full potential in practice, due to numerous reasons that have not been adequately addressed. Animal welfare reservations can be highlighted as one of the major contributing factors to the curbed progress. The consequences have been scientifically proven to affect product quality and market access. However, in the African community, the concept of animal welfare has not been fully embraced. While there are international animal welfare standards in the developed world, there are inherent factors that hinder adoption of such initiatives in most developing regions, particularly among communal farmers. These include cultural norms and practices, social ranking, socio-economic status, available resources, information dissemination and monitoring tools. Therefore, there is need to harmonize what is internationally required and what is feasible to accommodate global variability. The protocols followed to ensure and evaluate farm animal welfare require regular investigation, innovation and a sustainable approach to enhance animal productivity, efficiency and product quality. Additionally, investing in animal wellbeing and health, as well as empowering communities with significant knowledge, has a potential to improve African livelihoods and contribute to food security. This review seeks to highlight the concept of animal welfare in relation to livestock and food production in African conditions.
Water motion is one of the main drivers in morphological variability in species within de order Laminariales, and most of our current knowledge is based on subtidal populations. $Eisenia$$arborea$ is a dominant kelp species in the North Pacific, widely distributed along the Baja California Peninsula from mid intertidal down to subtidal areas. This species presents great variability in the intertidal zone but it has not been yet evaluated such variability according to wave exposure. The present work also identifies the spatial / temporal variation, particularly respect to the presence of stipes without medulla (hollow stipes) a feature common among other brown seaweeds. We evaluated the effects of wave action in morphological variation of intertidal $Eisenia$$arborea$ (Laminariales, Ochrophyta) at Punta Eugenia. The spatial and temporal variation sampling was surveyed between February, May, July, and August 2004 in the intertidal of Punta Eugenia, Baja California Sur. Our results have shown that exposed sites correlate with increased length and width of stipes as compared to more protected sites. Hollow stipes frequency changed more in association with temporal variation than with spatial heterogeneity suggesting nutrient limitation for thalli development. Our results suggest that $Eisenia$$arborea$ compensate by morphological modifications the stress of living in the intertidal zone by showing larger stipes. Hollow stipes might be are also a mechanical adaptation to increase survival in high energy environments.
This study examined the relationship between mothers' consciousness of diet and their infant feeding methods and weaning practices. Consciousness of diet analyzed from 17 questions concerning the attitudes and opinions of diet was classified into 6 categories using the factor analysis. These categories were the faithfulness of diet, the health-directed dietary practices, the application of health information, the application of information about food and nutrition, the sincerity to meal preparation, and dietary habits. The 400 mothers selected randomly from Wonju area were surveyed. The results obtained from the study were summarized as follows. Weaning was implemented earlier by the group with better education career and with the exact knowledge of weaning. Factors associated with infant feeding methods included some sociodemographic characteristics such as birth order, mothers' employment state and income level and mothers' effort toward faithfulness of diet. The use of health-foods and nutrient supplements were prefered by the groups used bottle-feeding method. The health condition of the infants was influenced by mother's will to carry out the health information rather than infant feeding methods and weaning foods used. Mothers who perceived the importance of diet for health and consumed more milk had healthier babies, and their dietary habits were more favorable. The subjects who self-recognized the meaning of weaning and who believed that earlier weaning was good for baby or delayed weaning was the cause of anemia and poor appetite, took advantage of the information about food and nutrition as well as prefered the health-directed dietary practices. Mothers who retried to feed the weaning food rejected by baby before, applied the dietary information to the real meal management more actively and had a more desirable dietary habits. In those cases the baby had improved health condition. Those who were interested in the meaning of weaning and the nutritious effect of weaning foods, revealed significantly higher tendency on the performance of cooking information and the more confidence to the health information from advertisement.
Numerous methods can be employed to teach students and farmers on soil science and fertilizer. The cartoon is one of the most effective teaching aids both for instructors and students. Instructor becomes a director of the cartoon to organize the framework of story based on the chapter of lecture. Director should adapt the regular sentence on soil science into the short and concise scenario suitable for the visual expression of the cartoon, followed by the selection of the scene for drawing. Next is to cast the instructor for the role of actor or sometimes supporter. After casting, the director starts to draw each cut of the cartoon in sequence. I published the cartoons in weekly serials in the farmer's newspaper for three years. Each cartoon was composed of eighteen cuts and formatted with the introductory, main and conclusive issues. Cartoon started with dialogues between the cast on subject to stimulate the interest by farmers, inserted the tables and graphs for the scientific knowledge and summarized the chapter. Major contents covered in the cartoons were glossary, nutrient uptake, pH, salt accumulation, moisture, pollution, chemical fertilizer, compost and other general aspects of soils. Cartoons had been very popular serial of the newspaper and are archived in the web for reviewing.
The nutritional balance of the menu plans prepared according to the target pattern was examined. Total of 81 home economics teachers throughout the nation and 161 3rd-grade middle-school girls in Chungnam area participated. The data was collected by questionnaire and analyzed by using SPSS WIN 12.0. Although both teacher and student groups had fairly good knowledge on preparing menu plans related concepts, they rarely make use any menu planning currently. More than 85% of menu plans investigated exceeded their energy goal in the target pattern. The energy contribution ratios of carbohydrate: protein: fat were 56.1%: 17.4%: 26.5% in teachers' menu plan and 55.1%: 17.2%: 27.7% in students' menu plan. The NAR of the protein, phosphorous, iron, zinc, vitamin A and C, thiamin, riboflavin, niacin, B6 was 1 or near 1. But in case of calcium, 56.5% of the menu plan prepared by the students was less than 1, and in case of folate 75.3% of teachers', and 85.1% of students' were less than NAR 1. The MAR of the 12 nutrients examined were 0.98, 0.97, and the DVS were 51, 49 for menu plan prepared by teachers and students, respectively.
This study was conducted to compare the awareness, satisfaction, and usage patterns of female-consumers for food-nutrition labeling in Busan. The survey was conducted from April 15 to June 10, 2018 by questionnaire. Degree of perception of food-nutrition labeling was higher among individuals in their 30s, 40s and 50s than those in their 20s, 60s and 70s. The score of verification degree was highest among respondents in their 40s and lowest among those in their 20s and 70s. Degree of demand of individuals in their 70s was lower than that of those in their 60s. Degree of reliability of individuals in their 30s, 40s and 50s was higher than that of those in their 20s, 60s, 70s. Satisfaction degree did not differ significantly among groups. Overall the most common reason to review food labeling was 'to confirm expiry date' (30.8%). Among those in their 20s, the main reason for reviewing nutrition labeling was 'weight control', while it was 'nutrients' among those in their 30s, 40s, 50s, and 60s, and 'health improvement' among those in their 70s. Additionally, 51.3% of the subjects reported that the major reason for difficulty understanding the labeling was 'small letter, various form'. The demand for nutrient contents was highest in sodium. Age was negatively correlated with perception of food-nutrition labeling, demand, need for education and publicity, and nutrition knowledge (P<0.01), whereas it was positively correlated with dietary attitude (P<0.01). There was a strong correlation between demand for food-nutrition labeling and the need for education and publicity regarding food-nutrition labeling (r=0.546). Therefore, education materials and improvement plans based on age should be developed and implemented to inspire individuals to choose more nutritious food and develop a healthy dietary life.
In this study elementary school children's food purchasing and consumer competency for a healthier diet were compared by their attitude toward the meal management. The subjects were 779 sixth grade elementary school children (417 boys and 362 girls) in Busan. They were classified into three groups: 'High' was composed of 226 subjects who had more than the mean +1/2 SD of attitude toward the meal management; 'Medium' was composed of 343 subjects who had the mean ${\pm}1/2$SD; and 'Low' was composed of 210 subjects who had the less than the mean -1/2 SD. The results were as follows. The high group had less pocket money than the low group, and thought that their allowances were adequate to their needs. They also had a habit of entering amounts into an account book. The children in the low group purchased mostly snacks without making or practicing a budget. The high group purchased yogurt, fruit, or bread as snacks more frequently than the low group. More children checked the nutrient facts on the package in high group than in the low group. There were no significant differences in the consumer's knowledge of a healthy diet among the groups; but there were significant differences in the consumer's skill, and the consumer's attitude toward a healthy diet among the groups. The high group had higher skills and more positive attitudes than the low group. This research suggests that education can elevate interest and can help develop more positive attitudes toward healthy diets among children. The education can help them to develop planned food purchasing habits, and improve their consumer competency for a healthy diet.
