  • The objectives of this study were finding out some methods about development of oversea agriculture in Korea. It is a tough task that faces us now. China is a big agricultural country, most agricultural investment country and the nearest located in Korea. So this study researches on the quality of farmers and characters of rural human resources in China. In China, agriculture industry is the basic industry among national economy developments. The majority of populations in China are living in rural region. Agriculture, villages and farmers are main issues in China. From this point, An analysis of Chinese farmers' characters and qualities; general conditions of farmers' knowledge of science and technology, their education level, quality of minds and sprit, and rural public health service situation in China. The result of this study is following; First, Chinese farmers' factors that low education level, big cultural differences between cities and country sides affect the development of China's agriculture as obstruction factors. Second, Practice conditions of farmers' science knowledge and technology are low level, output of higher rural human resources, low quality of minds and sprit and problems of agricultural extension service. It is negative influenced of agriculture and farmers economic development in China. Third, unsociable culture of the peasantry influences Chinese farming in the negative ways. Also, conventional notions of family are getting weaker, it makes connection of the kinship weaken. But, Chinese think that this kind of kinship is the most important thing in their life. Fourth, in the case of situations that the farmer's sanitation and health, low level of the medical service is getting worse than before relatively. And there are a lot of discordances between a planned childbirth policy and personal recognitions. Also, lacking of nourishment makes labor productivity falling tendencies. The medical industry falls short of the standard as compared to the number of farming people. Fifth, in the peasantry's consciousness of the legal system, this causes difficulties to farmers in the market. Shortage of the legal knowledge exerts a bad influence upon rural economy.

  • The present study was conducted to assess the status of vitamin C among healthy young adults in relation to serum antioxidant parameters [glutathione (GSH), thiols, and total antioxidant capacity, (TAC)], and oxidative stress markers [malondialdehyde (MDA), and nitrites plus nitrates (NN)]. A prospective study included 200 young adults, and their dietary intake was assessed by using food diaries. Fasting plasma vitamin C, serum levels of GSH, thiols, TAC, MDA, and NN were measured using biochemical assays. It was observed that 38% of the enrolled subjects, n=76, had an adequate dietary intake of vitamin C (ADI group). Meanwhile, 62%, n=124, had a low dietary intake of vitamin C (LDI group) as compared to the recommended dietary allowances. The fasting plasma level of vitamin C was significantly higher in the ADI group as compared to the LDI group. Oxidative stress in the sera of the LDI group was evidenced by depletion of GSH, low thiols levels, impairment of TAC, an elevation of MDA, and increased NN. In the ADI group, positive correlations were found between plasma vitamin C and serum antioxidant parameters (GSH, thiols, and TAC). Meanwhile, the plasma vitamin C was negatively correlated with serum MDA and NN levels. This study reveals a significant increase of oxidative stress status and reduced antioxidant capacity in sera from healthy young adults with low intake of the dietary antioxidant, vitamin C.

  • The health function food law has been carried into effect from January 31, 2004 just after the proposal of 'a draft of a proposed law concerning the health function foods for the promotion of a nation health' on November 29, 2000 in Korea. After enforcement of health functional food law, there have been difficult market penetration with overall stagnancy of business activities and the current of health functional food within the country divided two groups. In standardized health functional foods the present condition, nutrition supplementary products (938 items) and red ginseng products (351 items) are prevalent and total 32 products are registered containing lactobacilli (297 items), glucosamine (295 items), ginseng (182 items), yeast(136 items) so on. In 2005, five products (products containing green tea extract, soybean protein, plant sterol, fructooligo sugar and Monascus sp. products are newly notified and raw material or component of total 21 products containing xylitol, teanin extract, sardine peptide are recognized as individual authorized health functional foods. Efficacies of ginseng are studied in many-sided researches but benefits of the ginseng in the health functional food law limited to 3 items (staminaresume, immune enhancement, nourishment robustness). To enlarge functionalities of ginseng it needs raw material and ingredient approval through data application to Korea Food and Drug Administration and this procedure acts as barrier of the functional food development in the ginseng industry. It is necessary to develop the authorized health functional foods for leading health functional food market in the future.

  • Rice(Oryza stiva L.) is a major cereal food providing nourishment to over half of the world's populations and was considered only as a source of energy. However, The recent many researches have been made to suggest that rice may relate to prevention chronic disease and health-promoting properties such as postprandial glucose response, hypocholesterolemic effect and blood pressure-lowering effect. There has been numerous observation supporting that rice has hypocholesterolemic effect. Rice, rice bran, rice bran oil and unsaponifiable matter of rice bran oil reduced plasma cholesterol in rat, hamster as well as human. Components of rice showing hypocholesterolemic effect include dietary fiber(hemicellulose, phytic acid). protein, ${\gamma}$-oryzanol, $\beta$-sitosterol, and tocotrienols. Crapo et al has been studied that the effect of various of starchy foods on the postprandial blood glucose and insulin responses in healthy and diabetic humans. The results showed that rice had lower blood glucose and insulin responses compared to potato, bread and dextrose. The different physical forms in the same starch also produce the different postprandial glucose and insulin responses. In recent years, several studies have shown that some components of rice have potent antioxidant activity against Fe$^{2+}$ -ascorbate induced lipid peroxidation in rat liver microsomal membranes. Cell culture and animal studies have shown that some components of rice have inhibitory effect on the growth and proliferation of several types of human cancer cell. It was also reported that the methanol extract of brown rice has antimutagenic activity against various mutagens. In addition, the pepsine hydrolysate from rice protein is reported to inhibit angiotensin converting enzyme activity. GABA (${\gamma}$ - aminobutyric acid) and GABA enriched rice germ is also effective for lowering blood pressure and triglyceride levels.s.

  • BACKGROUND/OBJECTIVES: The level of serum albumin is an index of nourishment care and management. However, the distribution and correlates of serum albumin levels among individuals with motor disorders have not been reported until now. Therefore, we examined the distribution and correlates of serum albumin levels among individuals with motor disorders. SUBJECTS/METHODS: A cross-sectional study on 249 individuals with motor disabilities (144 men, mean age: 51.4 years; 105 women, mean age: 51.4 years) was conducted at five institutions in Ibaraki Prefecture, Japan in 2008. The results were compared with data from the National Health and Nutrition Survey. RESULTS: The mean serum albumin levels were $4.0{\pm}0.4g/dL$ for men and $3.8{\pm}0.5g/dL$ for women. Overall, 17 (11.8%) men and 25 (23.8%) women had hypoalbuminemia (serum albumin level ${\leq}3.5g/dL$); these proportions were greater than those among healthy Japanese adults (${\leq}1%$). Low serum albumin level was related with female sex, older age, low calf circumference, low relative daily energy intake, low hemoglobin (Hb), low blood platelet count, low high-density lipoprotein cholesterol (HDL-C), low $HbA_{1c}$, and high C-reactive protein (CRP) levels. The strongest correlates, based on standardized betas, were Hb (0.321), CRP (-0.279), and HDL-C (0.279) levels. CONCLUSIONS: These results indicate that the prevalence of hypoalbuminemia is higher in individuals with motor disabilities than in healthy individuals and that inflammation is a strong negative correlate of serum albumin levels. Therefore, inflammation should be examined for the assessment of hypoalbuminemia among institutionalized individuals with motor disabilities.

  • This research is to observe the shoreline changes in Jinha beach over the 50 years with aerial photographs and satellite images. The shoreline image feature was retrieved from the corrected images using wet and dry techniques and analyzed by DSAS from the statistical point of view. From 1967 to 1992, the mouth of Hoeya River was severely blocked and the northern shoreline off Jinha beach was eroded. The blockade of river mouth seemed to have been eased along with the completion of the dike, but soil continued to be deposited along the high sea away from the river month. Compared to the past, a layer of sediment has been formed off the northern coastline while the southern coastline has eroded. At least in the region subject to this research, the construction of a training dike is to blame. On top of that, a mere combination of dredges and artificial nourishment is not enough to take under control the changing shorelines properly. Thus, it is necessary to devise a more fundamental solution by taking into account reasons behind sediment from the river area that could change the shorelines besides the costal environment.

  • From the 1997 to January, 2004, a groin 156m long was constructed at the mouth of the Heoya river-mouth as a protection and barrier. To understand the changes to Jinha beach from the blockade of the river mouth, several aerial photographs, etc., were compared, which showed that the changes were significant. Comparing these results to the state of the area before construction of the groin, the blockade of the river was relaxed, but the formation of the tombolo, in the middle groin area was accelerated and the total Jinha beach erosion and especially the erosion of the southern part of Jinha beach was developed. But according to statements by residents and some current documents, the blockade of the Heoya-river mouth is still underway at the surrounding areas of the groin and chronic dredged sand has been used for littoral nourishment at the northern part of the middle groin and on Jinha beach. The result of numerical simulation based on the present state shows that if this sort of dredging is stopped, the sand accumulation will progress near the river mouth groin and the existing tombolo at the middle groin will progress to the north and severe erosion will occur at the southern coastline near the middle groin and the farthest southern part of Jinha beach, and Jinha beach itself will experience a gradual erosion. The main reason for these erosions should be the typhoons that are happening during the summer season. To provide protection from these kinds of undesirable erosions, a total of 23 numerical simulations have been done. It has been shown that submerged breakwaters at the front area of the beach will be efficient to protect from main beach erosion, but there should be alternative proposals for the influence of the river mouth blockade.

  • Rapid development in the upper reaches of the Mekong River, in the form of construction of large hydropower dams and reservoirs, large irrigation schemes, and rapid urban development, is putting water resources under stress. Many scientific reports have pointed out that cascade dams along the Mekong River lead to serious problems: not only hydrologically but also a decline of agricultural productivity due to a decrease of sediment supply in the Mekong Delta and a change of fish amount due to drastic change of the water environment. Cambodia and Vietnam, located in the lowest Mekong basin, are gravely affected by radical changes of hydrologic regime due to Mekong River developments. In particular, the Tonle Sap Lake in Cambodia is very sensitive to the flood cycle and flow variation of the Mekong River as well as inflow water quality from the Mekong River. More than 50% of Cambodian GDP depends on the primary industries such as agriculture, fishing, and forestry, and the Tonle Sap Lake plays an important role to support the national economy in Cambodia. In addition, Cambodian people usually take nourishment from the fish of Tonle Sap Lake. This research aims to assess the impacts of the Mekong river flow alternation on the hydrologic regime of the Mekong River - Tonle Sap Lake. We carried out rainfall-runoff-inundation simulation using CAESER-LISFLOOD for integrated water resource management in the Tonle Sap Basin and then analyze flood inundation variation of the Tonle Sap Lake due to the scenarios. Furthermore, the simulated inundation maps were compared to MODIS satellite images for model verification and hydrologic prediction.

  • The aim of this study is to find out the correlations between heaith behaviours of young people and the relationships with social factors, which can be helpful for the development of health promotion programmes for youths. The main socializing arenas influencing children's development of health and health behaviour are school, peers and parents. In this study, the selected social factors are based on these arenas. And the following seven health-related behaviours were selected: smoking, drinking alcohol, drinking coffee, irregularity of taking main meals, regular exercise, brushing teeth, and use of medicine for nourishment or restoratives. These health behaviours categorized into two groups; health- promotiong and health-damaging behaviours. The results were summarized as follows; Significant positive correlations were found between health damaging behaviours-drinking alcohol, coffee, smoking, irregularity of main meals, drinking alcohol. But, No consistently significant correlations were revealed among health promoting behaviours and between health promoting and health damaging behaviours. If total group were devided into four groups by gender and grade, these correlations were a little weak. Although such division, the correlations among health damaging behaviours were still significant. The result is also found that health behavious and various social factors were strongly correlated. Particulary, health damaging behaviours showed a consistent correlation with social factors. This consiatensy was simillar to the figure of other contries in Europe. In conclusion, a more comprehensive explanation on health behaviour bacame possible if the analysis on the correlations were made by dividing health behavious into "health-promotion" and "health- damaging". And the health promotion programmes can be more effective when they focus on the correlation of health behavious and inter-relationships between health behavious and various social factors, rahter than focus on individual behavious.

  • T'oegye placed great emphasis on the cultivation of quiet-sitting. His idea of quiet-sitting, like Zhu Xi's, had various therapeutic effects as well. This can be highlighted as a real-life practice and a diverse application of the "abiding by Gyong" that he stressed; it is also associated with the treatment of physical diseases, composure in the mind, the benefits of reading, meditation in solitude, and many other areas. And We can easily infer that T'oegye would have set some premises before referring to Hualin Simbang. First, he would have been wary of quiet-sitting being the goal of cultivation: Too much obsession with and emphasis on Toinsul would actually obstruct the practice of "abiding by Gyong" and mislead one's effort for the "preservation and nourishment of the mind" and "reflection and examination." T'oegye would have probably used the physical and breathing exercises in Hualyin Simbang mainly as a reference to treat his physical illnesses. Also, his Toinsul would have been employed independently and partially as a sort of supplementary practice-without being used in parallel with quiet-sitting as one of the methods to achieve reverent seriousness.
