The decommissioning project of the KRR 1 & 2 was started in January 1997. The actual decommissioning activity was started at the RI production facility and was finished at the end of 2002. The dismantling works of all components including the reactor structure of the KRR-2 was started in January, 2003 and will be carried out for 2 years till the end of 2004. The project schedule is estimated to delay for 4∼5 months beyond the original plan because of delaying on the cutting of thermal column nose and removal of the graphite bricks, but it may be caught up during the removal working of concrete from biological shielding structure. This paper summarizes the general status of the KRR 1 & 2 and decommissioning activities.

The purpose of this study is to investigate the nutritional status and dietary intake of gastrectomized cancer patients. For this study, from 1993. 1 to 1993. 8, 50 postoperative gastric cancer patients were selected to examine anthropometric and laboratory data(Body Weight, Body Fat, serum Albumin, Total Lympocyte count), and dietary intake related symptoms. The results were 1) All anthropometric and laboratory data were significantly deteriorated by gastrectomy(s-Albumin, TLC. Body Fat : p<0.001). Weight loss of gastrectomized patients was 8.23$\pm$3.72% from admission to discharge. 2) In many gastrectomized cancer patients, preoperative dietary intake was decreased by abdominal discomfort, indigestion, early satiety, and anorexia. 3) Postoperative energy intake was 602$\pm$158㎉, and it is correspond to 31.18$\pm$.90% of daily energy requirement(1918$\pm$236㎉). The cause of poor oral intake is mostly fear, abdominal distension and fullness, and early satiety. In consideration of the fact that an inadequate energy intake was the main cause of the decreasing nutritional status, a careful nutritional care and dietary education is necessry after gastrectomy.

The influences of depression and health anxieth on the elderly's drug use and nutritional status were evaluated by interviews with questionaire from August to October in 1996. One hundred and thirty-one male and 231 female elderly in Chung-buk area were the sample for this study. Men's depression score was 22.3 and 25.2 for women, respectively out of 27. Women showed a significantly higher score for depression and health anxiety than men. Gender, age, marital status, number of family, education, income, medical insurance, and mobility and region significantly affected the health anxiety score. The higher depression score the elderly had, the more frequently they took drugs. Conversely. the higher depression score the elderly had, the less frequently they took nutritional supplements. For women, the higher depression score the elderly had, the more they smoked. More depressed elderly showed a significantly smaller BMI compared to the less depressed ones. A negative correlationship existed between the depression score and the elderly's nutrient intakes, especially energy intake which showed a significant negative correlation. There were no significant differences between health anxiety score and nutrient intakes of men. Women who had a higher health anxiety score consumed more energy significantly. The depression score did not affect the elderly's blood biochemical indices. Women who had a low health anxiety score showed a significantly higher HDL-C level.

The number of abnormal operation procedures (AOPs) for mitigating a plant abnormal status amounts to about one hundreds for the most of 1000MWe optimized power plant (OPR1000) and it is expected that the number of AOPs would be increased to cope with an abnormal status occurred newly. However, it is not well organized for operators to select a proper AOP from alarms occurred in main control room (MCR) during a plant abnormal status. It may be a burden to operators since the selection of AOP to respond an abnormal status is authorized by operators. When multiple alarms occur in MCR, it would take more time to respond them than a single alarm. To reduce the efforts, various MCR operation support systems have been developed. The purpose of this study was to develop a multi-alarm pattern card to select an appropriate AOP effectively when multiple alarms occurs in a single upper layout (UL) of MCR. It can be applied for an operation support tool as well as an education tool.

Offshore wind farms (OWFs) should be promoted as part of global efforts to respond to climate change, and efforts to preserve biodiversity in terms of climate change adaptation should also be considered. However, the ecological status of marine birds related to OWFs on the Korean Peninsula, such as habitat and reproduction, are not well known. In this study, ecological reasons for the reproductive status of Black-tailed gulls in Korea and representation related to OWFs, the evaluation direction of marine birds related to OWFs was presented. In a review of the techniques for monitoring marine birds, it was confirmed that Korea also needs to provide basic status information on marine birds at the national level. In addition, this study analyzed the reproductive status and related research status of Black-tailed gulls, an important indicator and dominant species on the Korean Peninsula, in relation to marine development projects including OWFs. Furthermore, the direction of environmental impact assessment preparation and impact prediction for various development projects promoted in the ocean, such as OWFs, was considered.
