This study is based on data from the food consumption survey on 727 members of 125 farm households from 7 different provinces. The survey was conducted in May, 1975 in cooperation with the O.R.D. The results obtained in this study are summarized as follows. 1. The average consumption of the basic food groups per capita per day was 563 g for cereals and grains(398g of rice and 129g of barley), 87.6g for meats and legumes, 317.8g for fruits and vegetables, 25.7g for milks and small fishes, 9.1g for fats and oils, and 45.1g for other group. 2. The average daily consumption of calories and nutrients was 2256 cal and 11.7g for animal proteins, 70.5g for total proteins, 21.6g for fats, 537.4mg for calcium, 18.1mg for iron, 5375lU for vitamin A, 1.27mg for thiamine, 1.05mg for riboflavin, 15.5mg for niacin, 77.7mg for ascorbic acid. When these figures are compared with the recommended allowances for Korean, the calories and nutrients intakes were satisfactory, except for the intakes of animal protein which was below two third of the recommended allowance. 3. The diets of the projected villages differed from those of the non-projected villages in the following respect: (a) The amounts of animal proteins and fats were larger in the projected villages than in the non-projected villages. (b) The percentage contribution of fats to the total amount of calories from three nutrients, carbohydrates, proteins and fats was higher in the projected villages than in tile non-projected villages. (c) The percentage contribution from carbohydrates to the total amount of calories was higher in the non-projected villages than in the projected villages. 4. Certain physical and clinical symptoms were observed among the people in the rural areas, which can be related to the shortages of animal proteins and fats in their diets. It is recommended to pay special attention to the nutrition of school children in the Korean rural areas.

The General program evaluation guide is intended for use by managers of both deployment and R&D programs within the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE), although most of the examples of evaluations pertain to deployment programs(EERE,2006). It could help managers determine what kinds of timely adjustments may be needed in program design or implementation to improve the rate or quality of achievement relative to the committed resources. To consider the adaptation of the method in Korea, we have studied the evaluation case for solar america initiative using cost-benefit evaluation. The President's Solar America Initiative (SAI) was launched in January 2006 as part of the administration's Advanced Energy Initiative. The SAI has a goal of installing 5-10 GW of photovoltaic (PV) systems in the U.S. by 2015 and 70-100 GW of PV systems in the U.S. by 2030. The evaluation report presents estimates of the potential benefits should the SAI PV installation goals be achieved. For this analysis, the areas researched include energy, economic, and environmental benefits. As a result, research suggests that 500 MW of PV may have been enough to avoid lackout. The ability of PV to prevent specific blackouts will depend on very specific information on where the PV installations are installed and their ability to relieve pressure on the high stress points on the grid. While this level of detail is outside the scope of this study, it appears that there will be some potential benefit for blackout prevention should the SAI PV goals be achieved.

This study presents the impact of natural flow patterns on downstream fish habitat and economic outcomes in the Dal Stream, Korea. The study reach is 3.35 km long, located downstream form the Goesan Dam. To assess such impact, this study performed physical habitat simulations. The River2D model was used for the computation of the flow and the HSI model for the habitat simulation. Two physical habitat variables, flow depth and velocity, were used. The Zacco platypus, Zacco temminckii, Coreoleuciscus splendidus, and Opsariichthys bidens were selected as the target species in the study area. Using the building block approach (BBA), the scenarios for the hydropeaking mitigation were presented. Scenario 1 and scenario 2 were proposed by using the magnitude - duration concept and averaged the hydrologic data over the each month, respectively. Simulation results indicated that the scenarios effects significantly increased by about 18.6% for the weighted usable area (WUA). In addition, hydroelectric power benefits with both scenarios were investigated. It was revealed that the change of storing and releasing water decreased by about 27% for hydroelectric power benefits. In order to increase economic benefits, the scenario was modified with the discharges corresponding to the hydropeaking condition except the flood season. As a result, the hydroelectric power benefits were almost the same, however the aquatic habitat for the target species increased by about 5%. The change of dam re-operations through natural flow patterns provides an opportunity to minimize environmental and economic benefits in order to balance water management.
