In this study the stem analysis program, which can be operated with personal computer was developed to reduce time and cost of calculation, and to increase accuracy of analysis. The stem analysis method used in this program was compared with other methods. The results obtained were as follows : The value, 1/100mm measured from the latest annual ring measurement machine (Jahrringme${\beta}$geraete Johan Type II) was automatically inputed to the computer and saved into given file name. Turbo Pascal program was written to do this. The measured data was analyzed by stem analysis calculation program written by Fortran-77. Volume and height increments were approximated by spline function, and diameter of the stem disk was calculated by quadratic mean method. The increment values calculated by the programs were printed annually and in every five-year. Stem analysis diagram and several increment graphs were also easily printed. The result compared between those analysis methods showed that quadratic mean could reduce the error caused from eccentric pith. When the stem taper curve method, approximated by spline function, was used in the calculation of tree height and volume, increments would be more exactly calculated.

For debugging effectively the shared-memory programs with nested parallelism, it is important to detect efficiently the first races which incur non-deterministic executions of the programs. Previous on-the-fly technique detects the first races in two passes, and shows inefficiencies both in execution time and memory space because the size of an access history for each shared variable depends on the maximum parallelism of program. This paper proposes a new on-the-fly technique to detect the first races in two passes, which is constant in both the number of event comparisons and the space complexity on each access to shared variable because the size of an access history for each shared variable is a small constant. This technique therefore makes on-the-fly race detection more efficient and practical for debugging shared-memory programs with nested parallelism.

This study was undertaken to investigate the effect of cognitive rehabilitation program (CRP) using virtual content, for recovering patients with cerebrovascular disease (CVD). A total of 34 patients with CVD were divided into a control group and an experimental group, and subsequently subjected to a virtual content based CRP, followed by cognition, ADLs, and upper limbs. The control group completed a universal rehabilitation program (URP), and the experimental group was provided a URP and a virtual content based cognitive rehabilitation program. For both groups, respective programs were conducted twice a day, 5 times a week for 4 weeks. Both groups showed significant improvement in ADLs (p<0.05); but the amount of change in the experimental group 5 point improved significantly (p<0.05). Cognition was significantly different for both groups (p<0.05). However, the experimental group showed a greater change (2 point) than the control group when considering the amount of change (p<0.05). Comparing the amount of change in the upper extremity, the experimental group showed a significant change (0.7 point) than the control group (p<0.05). This study confirms that compared to URP, CRP using virtual content significantly improves ADLs and cognition.

The purpose of this study was to develop a web-based internet program for nutritional assessment and diet management of patient having hyperlipidemia. Hyperlipidermia were classified by hypercholesterolemia and hypertriglyceridemia. The program consisted of four parts according to their functions and contents. The first part explained the metabolism of lipids and defined the hyperchotesterolemia and hypertriglyceridemia. The second part is to assess the general health status such as body weight, obesity index, basal metabolic rate and total energy requirement by the input of age, sex, height, weight and degree of activity. This part also provides the Patient with menus lists and 1 day menu suitable to his weight, activity and the status of hyperlipidemia and offers the information for food selection, snacks, convenience foods, dine-out, behavioral modification, cooking methods, food exchange lists, and information on energy and nutrients of foods and drinks, and top 20 foods classified by nutrients. The third part is designed to investigate diet history of patient, that is, to find out his inappropriate dietary habit and give him some suggestions for appropriate dietary behavior. This part also offers on-line counseling and frequently asked Questions. The fourth part is evaluating their energy and nutrients intake by comparing with recommended dietary allowance for Koreans or standardized data for patient with hyperlipidemia. In this part, it is also analyzing energy and nutrients of food consumed by food group and meals, and evaluating the status of nutrient intake. These results are finally displayed as tabular forms and graphical forms on the computer screen.

The purpose of this study was to examine the comparison of physique with physical fitness according to TBS (Talented-Educational in Sport) program by H University in 2009-2011. For this study, 668 elementary students (2009: 297, 2010: 194, 2011: 177 or 1st: 506, 2nd: 104, 3rd: 58) were collected who aged 7 to 13 living in Seoul and Gyeonggi area. The subjects were measured on physique variables (5) and physical fitness variables (7). Mean comparisons (ANOVA) were conducted for each gender in order to compare the mean differences among attendance number. For association analysis, Pearson correlation coefficient was used to find association between the physique and physical fitness variables. Some physical fitness variables (sit up, half squat jump, side step, standing long jump, flexibility in male children; sit up, half squat jump, side step in female children) increased significantly in the attendance number but the physique variables did not. The results show that TES program was effective on the physical fitness variables (muscle endurance & agility) in sports talent children.

This study has developed an interactive WBI to enhance learning effects on 'the Moon motion' for middle-school students. The quality of this examined by applying it to 20 science teachers and 49 middle school students 49. As a result, over 85% of the test subjects gave an affirmative response in the interest induction, the curiosity solving, and the degree of learning participation category, the degree of difficulty item. Response of the students with negative perception on science have changed positively(p<.05) after this WBI learning. In addition, we compared the learners' of knowledge prior and subsequent to 'the Moon motion'. As a result, it was found that the case of 'no concept' was enhanced more than the case having 'partly or ambiguously concept' for 'the Moon motion'.

Purpose: In this study, we developed a new software tool for the analysis of renal scintigraphy which can be modified more easily by a user who needs to study new clinical applications, and the appropriateness of the results from our program was studied. Materials and Methods: The analysis tool was programmed with IDL5.2 and designed for use on a personal computer running Windows. For testing the developed tool and studying the appropriateness of the calculated glomerular filtration rate (GFR), $^{99m}Tc$-DTPA was administered to 10 adults in normal condition. In order to study the appropriateness of the calculated mean transit time (MTT), $^{99m}Tc-DTPA\;and\;^{99m}Tc-MAG3$ were administered to 11 adults in normal condition and 22 kidneys were analyzed. All the images were acquired with ORBITOR. the Siemens gamma camera. Results: With the developed tool, we could show dynamic renal images and time activity curve (TAC) in each ROI and calculate clinical parameters of renal function. The results calculated by the developed tool were not different statistically from the results obtained by the Siemens application program (Tmax: p=0.68, Relative Renal Function: p:1.0, GFR: p=0.25) and the developed program proved reasonable. The MTT calculation tool proved to be reasonable by the evaluation of the influence of hydration status on MTT. Conclusion: We have obtained reasonable clinical parameters for the evaluation of renal function with the software tool developed in this study. The developed tool could prove more practical than conventional, commercial programs.

When designing photovoltaic power plants in Korea, the prediction of photovoltaic power generation at the design phase is carried out using PVSyst, PVWatts (Overseas power generation prediction software), and overseas weather data even if the test site is a domestic site. In this paper, for a comparative study to predict power generation using weather information, domestic photovoltaic power plants in two regions were selected as target sites. PVsyst, which is a commercial power generation forecasting program, was used to compare the accuracy between the predicted value of power generation (obtained using overseas weather information (Meteonorm 7.1, NASA-SSE)) and the predicted value of power generation obtained by the Korea Meteorological Administration (KMA). In addition, we have studied ways to improve the prediction of power generation through comparative analysis of meteorological data. Finally, we proposed a revised solar power generation prediction model that considers climatic factors by considering the actual generation amount.
