Considering that the world population is expected to total 9 billion by 2050, it will clearly be necessary to sustain and even accelerate the rate of improvement in crop productivity. In the 21st century, we now face another, perhaps more devastating, environmental threat, namely climate change, which could cause irreversible damage to agricultural ecosystem and loss of production potential. Enhancing intrinsic yield, plant abiotic stress tolerance, and pest and pathogen resistance through agricultural biotechnology will be a critical part of feeding, clothing, and providing energy for the human population, and overcoming climate change. Development and commercialization of genetically engineered crops have significantly contributed to increase of crop yield and farmer's income, decrease of environmental impact associated with herbicide and insecticide, and to reduction of greenhouse gas emissions from this cropping area. Advances in plant genomics, proteomics and system biology have offered an unprecedented opportunities to identify genes, pathways and networks that control agricultural important traits. Because such advances will provide further details and complete understanding of interaction of plant systems and environmental variables, biotechnology is likely to be the most prominent part of the next generation of successful agricultural industry. In this article, we review the prospects for modification of agricultural target traits by genetic engineering, including enhancement of photosynthesis, abiotic stress tolerance, and pest and pathogen resistance associated with such opportunities and challenges under climate change.

The purpose of this study was to provide basic data for development of a recipe for muslim-friendly halal Korean foods through investigation of awareness of Korean foods, taste evaluation, and menu preferences. After Korean foods' menu range and standard were set up for the survey and in-depth interviews with three halal food experts were conducted, 35 kinds of halal Korean foods were examined. The present study conducted a survey on 205 foreign Muslims living in Jeonju-si, Jeonbuk and Gimpo-si, Gyeonggi who ate Korean foods. Foreign Muslims were male workers in their 20's residing in company housing, and their monthly mean income was 1.01~2 million KRW. The majority of subjects responded that meal problems were the most difficult in everyday life. Concerning the taste of Korean foods, the response rate of 'sweet' and 'spicy' was high while 'Korean food is healthy' and 'Korean food ingredients is fresh' were high for awareness of Korean foods. 'Bulgogi' was the most preferred among the selected Korean foods, which was in line with the results of previous research. There is a need to provide information on Korean foods that can be made with food ingredients certified as halal and their recipes through various media for foreign Muslims who have limitations on in meals due to religious factors.

To find the prevalence of the Farmer's syndrome and the related factors, we investigated 909 farmers who and older than 30 years and live in Choongju area. The farmers were interviewed individually with a questionnaire from July 18 through 31, 1997. The results are as follows; The prevalence of Farmer's syndrome was 21.0% in male and 45.1% in female. The age prevalence of Farmer's syndrome was higher in thirties and forties than fifties and over sixties in both sex. Farmer's syndrome was significantly higher in low educational status, low income, low family members and more than 20 years of farming group. However, Farmer's syndrome was significantly higher in non smoking and non alcohol intake group, there were no significant differences according to smoking and alcohol intake after stratification by sex. The most frequent symptom in male was lumbago(60.5%), the second was numb limb(49.8%), the third was shoulder stiffness(43.2%) and the fourth was dizziness(31.5%). In female, the most frequent symptom was lumbago(81.3%), the second was numb limb(70.2%), the third was dizziness(62.2%) and the fourth was shoulder stiffness(55.9%). All of these four symptoms are significantly higher in female than in male. With multiple logistic regression for Farmer's syndrome, sex(OR of female=3.3) number of family(OR of <=1.9) and duration of farming(OR of $\geq$2.0 yr=1.5) were turned out to be significant variables.

The purpose of this study was to find out the dietary attitudes and behaviors, intake frequencies of food groups, health-related opinions and practices, and sociodemographic characteristics of housewives in Wonju-Gun rural area. Interviewers asked 413 housewives about obove informations and then recorded. The results were as followes : Using the factor analysis processing, 17 questions about dietary attitudes and behaviors were categorized into 5 groups such as fidelity of diet, the healthful dietary attitudes, the eating practices concerning about items and amount, eating speed and the extent of coincidence in food preference within a family. The role of the housewives was a major factor affecting the dietary attitudes and behaviors. Those who work as housewives and farmers concurrently had good dietary practices concerning about items and amount, but they were interested about health-directed dietary attitudes at a significantly lower level. Food frequencies of 9 groups, animal protein food, fruits and vegetables, milk and milk products, small fishes such as anchovy, soybean curd and beans, seaweeds, vegetable oil, frying food, soybean paste were significantly associated with subjects' age, role, and education and income level. Whether or not intake of soybean paste was considered. protein food intake was altered, and the difference between two situations increased much more as age was higher. We noticed that intake of soybean paste improved the status of protein nutrition. Our subjects ate calcium sources and dishes using vegetable oil insufficiently. Those who had much interests for good health, revealed to be an active practitioner in the aspects of healthful dietary attitudes, but fidelity of diet, eating practices concerning about items and amount showed significant association with balanced life style.

An exploratory study was conducted in Gopalganj, a southern district of Bangladesh to explore the role of wild date palm (Phoenix sylvestris Roxb.) husbandry in the rural economy. A total of 36 households in the study area were interviewed using a semi-structured questionnaire. A multistage sampling method with 10% intensity and a semi-structured questionnaire were used for the study. Based on the land holding capacity of the households, the farmers were categorized into five groups as landless, marginal, small, medium, and large. The date palm was distributed over seven different habitats of which roadside support the highest value (31%) followed by agricultural field and orchard (25% each). Though the large category farmers own most of the palms (43%), a considerable portion (562 individuals out of 1980) of it is managed by the landless farmers, who earn a substantial livelihood from the palms. The farmers manage the palm mainly for juice production; juice is either used fresh as drink or after some sort of processing as molasses and/or alcoholic beverage. Date palm husbandry contributes 32,601 Tk., 21,107 Tk., 20,626 Tk., 29,574 Tk. and 35,335 Tk. respectively to the five group seasonally and 50,980 Tk., 77,556 Tk., 90,208 Tk., 112,560 Tk., 140,675 Tk. respectively annually (1 US$ = 70 Tk.). Date palm trees contribute 65.48% of mean annual income to landless farmers followed by 27.21% to marginal farmers. However the poor marketing system result in decreasing the annual return from palm trees. Palm husbandry could be a promising source of rural incomes in Bangladesh if the farmers' traditional management knowledge was linked to more scientific management practices.

This study aims to examine the effect of healing program using insect. For the insect resources, the program uses 3 species of emotional insects. The subjects were a total of 29, the elderly with mild dementia and adults with developmental disabilities in the facility. The activities are 9 programs in total and each program takes 2 hours once a week. For data collection, we measured a blood pressure, stress level using autonomic nervous system activity, and scale of happiness, depression and insomnia by a survey. The datas were collected every week before and after the program. As a result of paired-sample t-test analysis, the participants of the agro-healing program using insects had positive effects as follows: reducing a depression, relieving a symptom of insomnia and stabilizing a blood pressure. Through the results of this study, it was possible to confirm the positive effects of the agro-healing program using insects. If farms lead agro-healing program using insects on their own, it could be expected to contribute to improve the quality of life through agriculture as well as to improve the farms' income.

Recently, there has been increased attention to the development of new plant cultivars with enhanced resistance to biotic and abiotic stress. To develop ginseng cultivars with such traits, systematic breeding programs and comprehensive field studies are prerequisites. In this study, we applied a pure-line selection method to identify a ginseng cultivar with enhanced stress resistance. Phenotypic and agronomic characteristics, seed yield, and physiological responses to biotic and abiotic stresses were investigated according to the guidelines of the International Union for the Protection of New Varieties of Plants (UPOV). In the newly developed 'Kowon' cultivar, the time of emergence, flowering, and berry maturity were intermediate between those of the controls, 'Yunpoong' and 'Chunpoong'. The stem length of 'Kowon' was intermediate, whereas the root length was shorter and the main root diameter was greater than those of 'Chunpoong'. In local adaptability tests conducted in three regions, the yield of 'Kowon' was $666kg{\cdot}10a^{-1}$; 27% and 4% higher than that of 'Chunpoong' and 'Yunpoong'. Diseases such as Alternaria blight, Phytophthora blight, mulberry mealybug, and nematode infestation did not occur in 'Kowon'; and it also exhibited moderate resistance to damping-off and anthracnose. In these cases, yellow spots occurred on aerial parts and the rusty skin of the root, and it exhibited moderate resistance at high temperatures. Our study demonstrates that 'Kowon', which has a high root weight and enhanced biotic/abiotic stress resistance, is a superior cultivar that could increase farmers' income.

In spite of rapid sociocultural changes and an increase in the number of nuclear families in recent years, quite many families in Korea still have taken the extended family form where daughter-in-law provides care for the elderly parents. Even though the nature of the inter-generational relationship in Korea is reciprocal in many regards, most of the studies looked at the burden or costs of coresidence with the elderly parents while relatively little attention has been given to the positive side of the coresidence. This study is an attempt to fill this gap in the area. The purpose of this study is to examine not only the costs but also benefits of the coresidence with the elderly parents. We also explore whether there is a rural-urban differences in costs and benefits of coresidence and related factors. For the purpose, data were gathered from 876 daughters-in-law of three generational family both in rural and urban area, using structured questionnaire. The statistical methods used for data analysis were descriptive statistics, cross tables, and regression analysis with SPSS/PC+ program. The major findings of this study were as follows: Marital and economic status of the elderly parents, age, job status and filial responsibility attitude of caregiver, sibling support, and coresidence duration were the significant variables predicting the level of perceived benefits. Marital status of elderly parents, income, job status, educational level, and filial responsibility altitude of caregiver, residence region affected the level of perceived costs. Rural-urban differences are found in many aspects of coresidence experiences and related factors. Rural caregivers receive higher level of the sibling support, have more traditional final responsibility altitude and perceived less costs and more benefit than urban caregivers. There also are differences in the factors influencing the level of perceived costs and benefits between rural and urban area. Level of sibling support and final responsibility attitude have significant impact on both the perceived costs and benefits. But there are differences in terms of that perceived costs and benefits of urban caregivers are affected by job status of caregivers while those of rural caregivers are affected by educational level of caregivers and marital status of elderly. The results confirm that Korean caregivers experience both positive and negative aspects of coresidence and shows that the nature of the inter-generational relationships differ between rural and urban Korea.
