  • Necessity has compelled man to improve upon the art of tapping wind energy for power generation; an apt reliever of strain exerted on the non-renewable fossil fuel. The power generation in a Wind Farm (WF) depends on site and wind velocity which varies with time and season which in turn determine wind power modeling. It implies, the development of an accurate wind speed model to predict wind power fluctuations at a particular site is significant. In this paper, Box-Jenkins ARIMA (Auto Regressive Integrated Moving Average) time series model for wind speed is developed for a 99MW wind farm in the southern region of India. Because of the uncertainty in wind power developed, the economic viability and reliability of power generation is significant. Life Cycle Costing (LCC) method is used to determine the economic viability of WF generated power. Reliability models of WF are developed with the help of load curve of the utility grid and Capacity Outage Probability Table (COPT). ARIMA wind speed model is used for developing COPT. The values of annual reliability indices and variations of risk index of the WF with system peak load are calculated. Such reliability models of large WF can be used in generation system planning.

  • Background: Stomach cancer is an aggressive malignancy that is difficult to detect at an early stage and therefore is characterized by poor survival rates. Over the last two decades, there has been no report of gastric cancer survival in Khon Kaen province, Thailand. The aim of this retrospective cohort study was to provide up-to-date information about the survival of gastric cancer patients in this province. Materials and Methods: Data from Khon Kaen population-based cancer registry, Faculty of Medicine, Khon Kaen University were newly obtained on 650 patients who were diagnosed with stomach cancer during the period 1 January, 2000 to 31 December, 2012. These were then followed up until death or the end of the study (31 December 2014). We calculated the observed survival with the actuarial life table method, and relative survival, defined as the ratio of observed survival in the group of the stomach cancer patients to the expected survival in the entire Thai population from the estimated generation life tables for Thailand of five-year birth cohorts from 1900 - 2000. Results: The 5 year observed and 5 year relative survival rates were 17.2 % (95% CI: 13.54-21.14) and 18.2 % (95% CI: 14.3-22.4), respectively. The highest 5 year relative survival rates were demonstrated among patients aged 45-65, with stage I or II lesions, with adenocarcinomas, with a body of stomach location, well differentiated and receiving surgery and/or chemotherapy. Conclusions: The observed and relative survival rates were close to each other. Our findings provide basic information beneficial to development of an effective treatment system and appropriately improved population-based cancer registration.

  • The purpose of this study was to provide basic information for developing nutrition education programs for preschool children and their families. The subjects were 291 parents whose children went to daycare centers in Uiwang. The questionnaire contained 15 items for children's dietary habits and six items for parents' nutritional attitudes. The results of frequency analysis of children's dietary habits were as follows: 63.9% of children ate meals regularly, however breakfast (46.4%) was usually skipped; 44.0% of children ate a snack more than twice per day; 56.7% did not have late night meals; 49.5% ate out once to twice per week; 89.7% had dinner with family more than three times per week; and 43.6% had picky eating habits. The percentage of children who did not eat vegetables and seaweed was the highest among other food groups. Intake frequencies were low in fatty foods, instant foods, and fast foods. Some correlations were observed between picky eating habits and other dietary habits by cross-tabulation analysis. Intake frequency of non-picky eating children was lower for late night eating and fatty foods but higher for vegetables and seaweed compared to picky eating children. Parents answered that their nutritional knowledge level was normal (72.2%), and nutritional information was collected using the Internet (36.0%). Nutritional value was the most considered point in meal preparation of parents (43.3%), and the most difficult factor in child's diet management was lack of time due to working (36.1%). Parents cited method of creating a menu (27.0%) and table manners (25.3%) as topics of nutrition education by professionals. Therefore, various nutrition education programs need to be developed to improve healthy dietary habits for children and their families.

  • The objective of this study was to analyze the influences of forest management activity on the diameter distribution of Larix kaempferi Carriere stands in South Korea. We used 232 managed stands data, 47 unmanaged stands data of National Forest Inventory for this study. We employed the Weibull distribution function for estimating diameter based on percentiles and parameter recovery method. The results revealed that the average diameter breast height movements and growth of tree in the managed stands higher than the unmanaged stands according to the scenario: age, site index, and tree density change. The finding shows the percentage of the total amount of large class diameter was also high in the managed stands. The results of this study could be apply for the estimation of multi-products of timbers per diameter classes and stand structure development for Larix kaempferi Carriere stands in South Korea.

  • This paper deals with risk assessment of life in a landslide-prone area by a GIS-based modeling method. Landslide susceptibility maps can provide a probability of landslide prone areas to mitigate or proper control this problems and to take any development plan and disaster management. A landslide inventory map of the study area was prepared based on past historical information and aerial photography analysis. A total of 550 landslides have been counted at the whole study area. The extracted landslides were randomly selected and divided into two different groups, 50% of the landslides were used for model calibration and the other were used for validation purpose. Eleven causative factors (continuous and thematic) such as slope, aspect, curvature, topographic wetness index, elevation, forest type, forest crown density, geology, land-use, soil drainage, and soil texture were used in hazard analysis. The correlation between landslides and these factors, pixels were divided into several classes and frequency ratio was also extracted. Eventually, a landslide susceptibility map was constructed using a logistic regression model based on entire events. Moreover, the landslide susceptibility map was plotted with a receiver operating characteristic (ROC) curve and calculated the area under the curve (AUC) and tried to extract a success rate curve. Based on the results, logistic regression produced an 85.18% accuracy, so we believed that the model was reliable and acceptable for the landslide susceptibility analysis on the study area. In addition, for risk assessment, vulnerability scale were added for social thematic data layer. The study area predictive landslide affected pixels 2,000 and 5,000 were also calculated for making a probability table. In final calculation, the 2,000 predictive landslide affected pixels were assumed to run. The total population causalities were estimated as 7.75 person that was relatively close to the actual number published in Korean Annual Disaster Report, 2006.

  • Objective : This study grasps specific task on paramedics who plays a great role in the emergency scene, thereby eliciting definition of job called paramedics and analyzing occupation by DACUM method. Thus, the aim is to suggest working-level guidelines on the task of paramedics. Methods : It targeted paramedics who are working at hospitals, fire stations, and industries in Seoul and Gyeonggi area from Oct. 11, 2010 to Nov. 30. A total of 608 copies of questionnaire were analyzed by DACUM method. A research tool on occupational analysis consisted of 8 pieces for duty, 43 pieces for task, and 149 pieces for task elements. In order to survey performance frequency, importance, and difficulty by element, each task was developed by this research team, and each task was analyzed and finally elicited through workshop of DACUM method. Results : The occupational definition of paramedics, which was defined through this DACUM, was elicited as 'professional job of performing emergency medical care on the scene, during transferring, or within medical institution in order to maintain life and prevent wound deterioration, targeting a person who is put in emergency situation.' Task element, whose performance frequency was indicated to be the highest, was in order of checking mental status($2.76{\pm}0.497$), checking vital signs($2.70{\pm}0.578$), and airway/c-spine immobilization($2.69{\pm}.546$). Especially, defibrillation stood at $2.23{\pm}.655$ points. Task element, whose performance frequency was low, was in order of caring sexual abuse victims($1.32{\pm}0.563$), performing cricothyrotomy($1.36{\pm}0.618$), and caring cardiac arrest victims($1.40{\pm}0.636$). Importance of task was in order of airway/c-spine immobilization ($2.88{\pm}0.338$), maintenance of respiration($2.88{\pm}0.351$), caring cardiac arrest victims($2.87{\pm}0.349$), and performing CPR($2.87{\pm}0.361$). Task element, whose importance is low, was indicated to be in order of enema($2.29{\pm}0.736$), urinary catheterization($2.35{\pm}0.664$), and nasogastric intubation($2.35{\pm}0.667$). Task element, whose difficulty was shown to be the highest, was indicated to be in order of caring cardiac arrest victims during pregnancy ($2.60{\pm}0.559$), caring cardiovascular injury($2.59{\pm}0.546$), and labor management($2.53{\pm}0.533$). Conclusion : Based on the results of this study, the job performance work table(Dacom chart) of paramedics is suggested to be used, thereby being applied to development in education and curriculum of paramedics. It is necessary to evaluate usefulness of the job performance work table by estimating effect of education for paramedics based on the job performance work table of paramedics.
