DEM (Digital Elevation Model) is a useful dataset which represents the earth surface. Beside many applications, production and frequent update of DEM is a costly task. Recently global satellite based DEMs are available which has huge potential for application. To check the accuracy, this study compares two global DEMs: AW3D30 (Advanced Land Observing Satellite World 3D 30m) and SRTM30 (Shuttle Radar Topography Mission Global 30m) with reference resampled LiDAR DEM 30m in a test area around Chuncheon, Korea. The comparison analysis was based on statistics of each DEM, their difference, profiles, slope, basin and stream orders. As a result, it is found that SRTM30 and AW3D30 were much similar but inconsistent in the test area compared to the LiDAR30 DEM. In addition, SRTM30 shows less difference with LiDAR30 compared to the AW3D30 DEM. But, DEMs should be very carefully examined for area which has temporal or season changes. For basin and stream analysis, global DEMs can be used only for regional scale analysis not local large scales.

The current study developed the analysis program by employing the Polygon Clipping Algorithm to calculate the open area on the court when players try to spike a ball. The program consists of two kinds of output screen. First, on the main output screen, it is possible to calculate both blocked area by net and blockers, and opened area to avoid the blocked area when players spike the ball. Additionally, the secondary output screen shows the moving path of setter and the location of set. Main output screen indicates hitting points of spiking, blocking, and open area. Also, it is possible to analyze the movement of setter, location of set, and hitting point of attacker. The program was tested by comparing real coordinate value and location coordinate value which is operated on the program. To apply this program in the field, future study needs to develop the program that can calculate three dimensions coordinate fast by tracking the location of players or ball in real time.

This paper is results of analyzing the characteristics of rainfall triggering landslides and geometry of slopes, caused by the heavy rainfall and antecedent precipitation by Typhoons Ewiniar and Bilis at Chuncheon area in Gangwondo around July in 2006. As results of analyzing the characteristics of rainfall, landslides in 131 sites were found to happen due to the heavy rainfall having the maximum intensity of rainfall in an hour during July 15 and antecedent precipitation during July 12 to 14 causing the ground to be weak by increasing the degree of saturation previously. From results of analyzing the geometrical characteristics of 131 slopes where landslides occurred, the slope width were in the range of 6~10m. The average slope length and angle were 46m and $51.8^{\circ}$, which was relatively steep slope, respectively. Landlises occurred in the elevation of 400 - 500 m with the most probable frequency.

We report a very rare case of a rapidly calcified chronic epidural hematoma (EDH) in a neonate. A 26-day-old female infant was referred to us from a regional hospital because of drowsy mentality and a seizure attack. She was delivered through caesarian section because normal spontaneous vaginal delivery was prolonged and failed. At birth, mild scalp swelling was found on the right frontal area. Scalp swelling was spontaneously resolved and she was discharged without any problems. On the 25th day after her birth, the baby presented with drowsiness and hypotonia following a generalized tonic-clonic seizure. Magnetic resonance imaging (MRI) and a computed tomography (CT) scan revealed a chronic EDH that had a thick layer of calcification. A small burr-hole trephination was performed and a single silastic drainage catheter was inserted. After the operation, a total of 12 ml of liquefied hematoma was drained, and the patient's mentality improved from drowsiness to alertness. The patient was asymptomatic when discharged.

This study investigated and analyzed the current status and operations of tourism farms in the Chuncheon area. By adopting the GIS, an analysis was made of whether the five old tourism farms utilized suitability and how they could open a new one in a suitability. The following results were drawn from the analysis of natural and social suitability factors and accessibility. Time requirements were analyzed taking into account that a majority of tourists came from Seoul and Gyeonggi, area. Four of the five tourism farms were within one hour travel, from these areas but it seemed impossible that they could be reached within one hour considering the actual road conditions and traffic. The natural and social suitability factors of a tourism farm were overlay-analyzed. The land of the first and second class that was considered to be suitable for a tourism farm was $17.12km^2$, which accounted for 1.38% of the entire area examined in the study and 11.50% of the entire agricultural land. The area that was evaluated to be suitable for a tourism farm will be able to attract new tourism farms in the future.

Objective : To evaluate the incidence of postsurgical sensory complications in patients with scalp masses and classify the locations of them from a surgical standpoint according to anatomical considerations. Methods : A total of 121 patients who underwent surgery for scalp mass were included in this study. The authors reviewed medical records and preoperative radiologic images. We investigated the complications related to sensory changes after procedure. Enrolled patients have been divided into three groups. Group A included patients with tumors above the superior nuchal line (SNL), Group B with tumors within the trapezius muscle area and patients who had tumors on the lateral trapezius muscle area were assigned to Group C. We compared the incidence related to postoperative sensory complications and summarized their additional treatments for these with clinical outcome. Results : There were 12 patients (10%) with sensory complications related on the mass excision site (Group A : 1 patient, Group B : 2 patients, Group C : 9 patients). Six patients were affected with lesser occipital nerve (LON), 2 patients on greater occipital nerve (GON) and 4 patients on GON and LON. Over 6 months after surgery, two of the twelve patients with sensory complications did not have complete recovered pain in spite of proper medications and local chemical neurolysis with 1.0% lidocaine and dexamethasone. Conclusion : Occipital neuropathy should be considered as a complication related excision of scalp mass. The sensory complications are more frequent in Group C because of the anatomical characteristics of the occipital nerves and there were no statistical difference for other variables.

Rural Development Administration has recently developed mid-late maturing rice cultivars with high quality. This study was conducted to select suitable mid-late maturing rice cultivar in major cultivation areas of Gangwon Province among domestic breeding cultivars for 2 years from 2013 to 2014. The average air temperature during the experiment in 2013 and 2014 was higher $0.6{\sim}1.1^{\circ}C$ in Chuncheon, $1.0{\sim}1.3^{\circ}C$ in Gangreung, and $0.1{\sim}0.7^{\circ}C$ in Cheolwon than normal year. Precipitation in ripening period was higher 52.5 mm in 2013, but lower 176.4 mm in 2014 than normal year in Chuncheon, lower 103.1 mm in 2013 and higher 42.9 mm in 2014 in Gangreung, lower 225.9~322.7 mm in Cheolwon. Duration of sunshine in ripening period was higher 142 hours in Chuncheon, 108 hours in Gangreung, and 94 hours in Cheolwon than normal year in 2013, higher 20~21 hours in Chuncheon and Gangreung, and 82 hours in Cheolwon than normal year in 2014. Milled rice yield of 'Samgwangbyeo' and 'Daebobyeo' was 594 kg per 10a, and 578 kg for 'Jinsumibyeo' in Chuncheon in plain area. For Gangreung in east coastal area, the yield of 'Daebobyeo' was 555 kg per 10a, 'Hopumbyeo' was 554 kg, and 'Chilbobyeo' was 546 kg. For Cheolwon in mid-mountainous area, the yield was 504 kg per 10a for 'Daebobyeo' and 489 kg for 'Haiamibyeo'. But there was no difference in milled rice yield among cultivars tested in the study at each area. Head rice ratio of 'Haiamibyeo', 'Jinsumibyeo', and 'Mipumbyeo' in Chuncheon was 94.2~95.6% higher than the other cultivars. In Gangreung head rice ratio of 'Hopumbyeo', 'Haiamibyeo', and 'Samgwangbyeo' were 85.2~88.3% but there was no difference among cultivars except 'Gopumbyeo' and broken rice ratio of 'Haiamibyeo', 'Samgwangbyeo', and 'Mipumbyeo' were low as 7.5~8.5% and palatability of 'Mipumbyeo' was higher than the other cultivars. Head rice ratio of 'Daebobyeo' was the highest as 89.2% and there was no difference in broken and chalky rice ratio and palatability among cultivars in Cheolwon. Considering rice yield and quality in major cultivation areas of Gangwon Province, suitable mid-late maturing rice cultivars were 'Samgwangbyeo', 'Haiamibyeo', and 'Jinsumibyeo' in Chuncheon, 'Daebobyeo' and 'Chilbobyeo' in Gangreung, and 'Daebobyeo' and 'Haiamibyeo' in Cheolwon. The results obtained in the study imply that the selected cultivars with high yield and quality and suitability to Chuncheon, Gangreung, and Cheolwon, respectively could be recommended to rice cultivating farmers in the regions with high priority.

The effects of a four-week weight control program including nutrition, exercise, behavior modification and meditation were studied in 15 obese children who resided in the Chuncheon area. There were no differences in anthropometric value, health perception, self-esteem and nutrition knowledge before and after the nutrition education program. Food behavior significantly improved after the program, especially in the area of binge eating (p〈0.05). Consumption of ramyon and fried chicken significantly decreased (p〈0.05). These results showed that short-term nutrition education programs did not do enough to change the anthroppometric value of study subject. These results suggest that it is necessary to include parents in nutrition education programs for greater effectiveness. And there is a need to develop an apply systematic nutrition education programs to reduce the weight of obese children.
