This study attempts to make a constructive contribution to the debate on which WTO rules accommodate trade measures for environmental purposes. Does trade undermine the regulatory efforts of governments. However, the theoretical dimensions are partly addressed on the several key questions. For instances, is economic integration through trade and investment a threat to the environment? to control pollution and resource degradation? Will economic grow driven by trade help us to move towards a sustainable use of the world's environmental resources? The growing world economy has been accompanied by environmental degradation including deforestation, losses in bio-diversity, global warming, air pollution, depletion of the ozone layer, overfishing and so on. The sheer number of us obviously put pressure on natural resources and ecological systems, and this pressure will counting to rise as we grow towards 10 billion in the next century. What is more, there is no indication that consumption per capita is slowing. The perceived costs of acting alone in terms of lost investments and jobs often take the stream out of regulatory initiatives. In the worst case scenario environmental community is fearful that international trade will magnify the effects of poor environmental polices in the world Generally, economic growth drive by trade may speed up the process of environmental degradation unless sufficient environmental safeguards are put in place. Under these circumstances, this paper attempts to make a constructive contribution to the study on which WTO rules accommodate trade measures for environmental purposes.
This study was conducted to determine the interaction of dietary wheat bran and dietary calcium levels n)n calcium utilization in post-breeding female rats. It was designed to compare the effects of four different levels (2.5, 5, 10 and 20%) of wheat bran and two different levels (0.5 and 1%) of calcium on bone and calcium balance in post-breeding female rats over a ten-week period. The effects of diet on animal weight gain, serum calcium, femur weight, femur calcium concentration, bone mass and calcium balance were determined and statistically analyzed. The addition of 20% wheat bran significantly (p$\leq$0.05) decreased the weight gain of rats. Serum calcium and bone calcium contents were more affected by dietary calcium level than by dietary wheat bran level. There was no significant difference in fat-free solid, ash, percentage of ash to fat-free solid and percentage of calcium to ash among groups. Groups fed the 1% calcium diet had a higher percentage of calcium to fat-free solid. All rats were in positive calcium balance during the three-4ay experimental period. The average calcium balance of the rats fed 1% calcium diet ranged from 25.34 to 53.90mg and the average calcium balance of the rats fed the 0.5% calcium diet ranged from 26.71 to 32.90mg. In rats receiving 2.5% wheat bran, the difference in calcium balance between the group fed the 1% calcium diet and the group fed the 0.5% calcium diet was only 1.37mg, which was not significantly (p$\leq$0.05) different. In rats receiving 20% wheat bran, the difference in calcium balance between the group fed the 1% calcium diet and the group fed the 0.5% calcium diet was 19.S7mg, which was significantly (p$\leq$0.05) different. The addition of wheat bran caused an increase in the calcium balance of the rats adminslesed the 1% calcium diet. On the other hand, the addition of wheat bran had no effect on the calcium balance of the rats adminislesed the 0.5% calcium diet. In conclusion, calcium utilization of rats wire more positively affected by the interaction of both dietary wheat bran levels and dietary calcium levels than either dietary wheat bran levels or dietary calcium levels alone. Moderate wheat bran consumption did not interfere with the calcium metabolism of rats when calcium intake was high enough.
Coffee consumption in Korea has been currently growing every year, and as a result, approximately 0.2 million tons of Spent Coffee Grounds (SCG) are being created every year. SCG, which is waste organic material, is often classified as food waste and an annual amount of 0.27 million ton is discarded while containing moisture and provoking serious environmental issue. Physico-chemical characteristics of SCG were analyzed in this study and medium and long-term growth experiments were conducted in order to evaluate its utilization potential. According to the experiment results, mixing SCG into the previous base material resulted in accelerated germination and growth in the mid-term compared to previous base material alone, despite slower germination or growth in early stage. Especially, it showed lower withering rate and decrease in various symptoms that are caused by nutrition shortage in case of discontinued sprinkling, etc., compared to the previous base material. Hence, while SCG has a feature of hindering early development due to its feature of waste organic material that is rich in nitrogen, its benefit for long-term growth coming its moisturizing ability and supply of organic matter was confirmed in the study. On balance, SCG is believed to be a material that can replace or complement the previous base materials.

Two experiments were conducted to determine the effects of Leucaena leucocephala (leucaena) and Gliricidia sepium (gliricidia) supplementation on intake, digestion, outflow rates, microbial protein yield and live-weight changes in sheep fed with ammoniated rice straw (ARS). In experiment 1, three rumen cannulated Japanese Corriedale wether (mean body weight of 35.6 kg) in $3{\times}3$ Latin Square Design were used. Animals were fed ad libitum ARS alone, or supplemented with 200 g of either leucaena or gliricidia. In experiment 2, twenty-four growing native Philippine sheep with average body weight of $13.5{\pm}0.25kg$ were used in a completely randomized design (CRD) and offered similar diets to those of experiment 1. Supplementation increased total dry matter intake and nutrient digestibility except for fiber (p<0.05) without affecting ARS consumption. Nitrogen balance revealed that absorbed and retained N was significantly higher in leucaena and gliricidia. The significant improvement in N utilization and more digestible OM intake brought about by the inclusion of leucaena and gliricidia to ARS resulted in increased (p<0.05) microbial N yield. Efficiency of microbial N supply in supplemented group was not significantly different, but higher (p<0.05) than the 24.92 g N/kg DOMR for ARS group. Liquid outflow rate was 7.8 and 6.8 %/h, while the solid phase of rumen digesta was 4.4 and 3.8 %/h for the leucaena and gliricidia group respectively, which were significantly higher than 5.30 and 2.50 %/h in the control diet. The increase in total DMI resulted to higher (p<0.01) growth performance and efficient feed utilization. Average daily gain (ADG) was 19.3, 34.6 and 33.9 g/d for the ARS, leucaena and gliricidia respectively. It is therefore concluded that addition of leucaena and gliricidia to ARS in could increase nutrient intake and digestibility, subsequently improving N utilization and livestock performance.
In 2008, baby formula containing melamine was found to be responsible for a large outbreak of renal failure in infants in China. A total of 294,000 infants were hospitalized, and at least 6 babies died due to ingestion of the tainted formula. Melamine contains high levels of nitrogen (>60%), which is used as an indicator of protein content. Therefore, high levels of melamine in infant formula were thought to be the result of deliberate contamination m an attempt to increase its apparent protein content. Following inspections by China's national inspection agency, assorted products from at least 22 dairy manufacturers across China were found to have varied levels of melamine (range: 0.096196.61 mg/kg). Melamine co-exposure with cyanuric acid can induce acute melamine-cyanurate crystal nephropathy, which can lead to renal failure at much lower doses than if either compound were ingested alone. However, currently, there are very few data on melamine analogues other than cyanuric acid. At an expert meeting of the WHO and FAO held to review toxicological aspects of melamine and cyanuric acid on December 14, 2008, a new tolerable daily intake (TDI) of melamine was established that could be applied to the entire population, including infants. Therefore, a risk assessment of the various theoretical melamine contamination levels in infant formula and selected representative foods (other than infant formula and sole-source nutrition products) is urgently needed for Korean babies and children up to 7 years of age. Although the undetectable level regulation for infant formula may be low enough to guarantee the safety of babies under the age of 1 year (including premature babies), the melamine standard of 2.5 ppm for foods other than baby formula could be insufficient to protect the 95th percentile population aged 1~2 years because of this demographic's high consumption of milk, yogurt, and soy milk (hazard index = 1.79). Because TDIs are chronic values intended to protect an individual over his/her lifetime, occasional modest ingestion in excess of the TDI is not likely to be a health concern. However, children aged 1~2 years may have renal systems that are comparatively more sensitive to the crystallization of melamine and its analogues. Therefore, governmental jurisdictions may need to practice more prudent management of food items that could raise the melamine exposure for this population.

This study was performed to investigate the repeated-dose toxicity of Leuconostoc citreum GR1 (Leuc. citreum GR1), a lactic acid bacterium isolated from kimchi, in male and female rats. Sprague-Dawley male and female rats were divided into four group (ten animals in each group) and Leuc. citreum GR1 was administered daily by gavage to rats at dosage levels of 0, 500, 1,000, or 2,000 mg/kg/day for four weeks. There were no bacterial-related deaths or abnormal clinical signs in either gender of rats during the observation period. Furthermore, no differences were found between the control and treatment groups in terms of body weight, food intake, and water consumption. Hematological parameters, serum biochemical analysis, and histopathological examination also showed insignificant dose-dependent alterations. There were also no alterations in organ weights upon administration of Leuc. citreum GR1 alone. These results suggest the oral application of Leuc. citreum GR1, up to a dosage level of 2,000 mg/kg, causes no adverse effects in both male and female rats.
Pregnant CD-1 mice were exposed to methylmercury in the drinking water at concentration of 20ppm with subcutaneous treatment of thiaminHCl(vitamin $B_1$) (100mg, 200mg or 300mg/ kg b.w.) or BAL(5.0 mg/kg b.w.) under the alone or combined base at the therapeutic agents from day 6 to 15 of gestation. Fetal growth parameters, including body weight and crown-rump length in the mice exposed to mercury, were reduced as placental weight compared to those in the control group(no treatment). The incidence of dead fetuses/resorption and malformed fetuses(especially cleft palate) was also increased even in the group treated with thrapeutic agents as well as in the mercury only treated group. However, all kinds of alteration indicated above, possibly induced by mercury, reduced/or decreased significantly compared to those of control. A subtle indication of maternal toxicity was noted in most experimental animals as evidenced by decreased water consumption and increased relative liver weight. The present study confirmed that methylmercuric chloride is embrytoxic and teratogenic in CD-1 mice when administered during organogenesis and that thiamin administration may have therapeutic application for the treatment or prevention against of deleterious effects induced by mercury during gestation period.
Objectives: The rise of one-person households may have consequences for food consumption patterns, and eating habits. This study investigated the home meal replacement (HMR) use and eating habits among adults in their 20s-30s living in one-person households. Methods: A total of 247 adults aged 26-39 years participated in this study. The subjects were divided into three group according to the household type; one-person households (n=80), two-person households (n=49), and multi-family (three and more members) households (n=118). Their use of HMRs (classified as ready-to-eat, ready-to-cook, and fresh convenience foods) and their eating habits were all compared. Results: The mean age of the subjects was 30.5 years, 47.8% were male, and there was no significant difference in age, gender, occupation, and monthly income according to the type of household. The intake frequency of total HMR and ready-to-eat foods was significantly higher in one-person households among the three groups. People in one-person households consumed more HMRs alone, and spent more money to buy HMRs. Undesirable dietary habit scores like unbalanced eating (p<0.05) and eating salty foods (p<0.05) were significantly higher in the one-person households. Among the total subjects, the unbalanced eating scores showed a significant positive correlation with the intake frequency of ready-to-eat foods, while the unbalanced eating scores showed negative correlation with the preference of fresh convenience foods. The scores for eating salty foods showed a significant positive correlation with the intake frequency and preference of ready-to-eat foods and ready-to-cook foods, while there was negative correlation with the intake frequency and preference of fresh convenience foods. Conclusions: Adults in their 20s-30s in one-person households consumed more ready-to-eat foods than those in multi-family households. In addition, people with one-person households had more unbalanced diets and ate more salty foods, and these undesirable eating habits showed a significant positive correlation with the use of ready-to-eat or ready-to-cook foods. These results should be addressed for producing healthier ready-to-eat/ready-to-cook foods and implementing nutrition education for making healthy food choices of one-person households, which are steadily increasing.
Obesity has become a worldwide health problem. Orlistat, an inhibitor of pancreatic lipase, is currently approved as an anti-obesity drug. However, gastrointestinal side effects caused by Orlistat may limit its use. In this study the inhibitory activities of dandelion (Taraxacum officinale) against pancreatic lipase in vitro and in vivo were measured to determine its possible use as a natural anti-obesity agent. The inhibitory activities of the 95% ethanol extract of T. officinale and Orlistat were measured using 4-methylumbelliferyl oleate (4-MU oleate) as a substrate at concentrations of 250, 125, 100, 25, 12.5 and $4\;{\mu}g/ml$. To determine pancreatic lipase inhibitory activity in vivo, mice (n=16) were orally administered with com oil emulsion (5 ml/kg) alone or with the 95% ethanol extract of T. officinale (400 mg/kg) following an overnight fast. Plasma triglyceride levels were measured at 0, 90, 180, and 240 min after treatment and incremental areas under the response curves (AUC) were calculated. The 95% ethanol extract of T. officinale and Orlistat, inhibited, porcine pancreatic lipase activity by 86.3% and 95.7% at a concentration of $250\;{\mu}g/ml$, respectively. T. officinale extract showed dose-dependent inhibition with the $IC_{50}$ of $78.2\;{\mu}g/ml$. A single oral dose of the extract significantly inhibited increases in plasma triglyceride levels at 90 and 180 min and reduced AVC of plasma triglyceride response curve (p<0.05). The results indicate that T. officinale exhibits inhibitory activities against pancreatic lipase in vitro and in vivo. Further studies to elucidate anti-obesity effects of chronic consumption of T. officinale and to identify the active components responsible for inhibitory activity against pancreatic lipase are necessary.

Focusing on increasing of single-person households this study aims to develop a scale to measure the healthiness of lifestyle among single-person households. The concept of healthiness of lifestyle is based on the theories of family strength and family ecology. We draw 50 items that encompass basic needs, individual, familial, and social aspects of single-person life. Using a sample of 317 persons who live alone, this study examined a factor structure of the items and selected 44 items based on the results of factor analysis. Reliability and criterion- and construct validity were also examined. The final scale consists of four domains; basic needs (finance, housing, consumption, and future plan), work·life balance (time management, health, and stress), family relations, and social participation (social network, social interests, and community participation). This scale can be used as an assessment measure of the healthiness of lifestyle of single persons who participate in programs in Healthy and Multicultural Families Support Centers.
