The authors studied on the problems concerning to the establishment of vineyard at 25% slopped land with 50㎝ in soil depth. We investigated on the effects of manure, mulching, physiological disorder and personal expenditures for establishment of the vineyard. The results obtained can be summarized as follows; About thirty person per 10a were required for establishment of planting step. Growth of the vine was not different 50-100㎝ of soil depth from over 100㎝ of soil depth. About 30% of selected vine trees showed boron deficiency on the young leaves and flower cluster during early June and that 70% of the vine trees showed blackish berry caused by boron deficiency during early July. The vine mulched with straw, depth of 7㎝ and 15㎝, showed significantly larger shoot growth than that of control. 15kgr. of manure application per tree showed significant difference in growth than 5kgr.of manure, 5kgr. of hen maunre and control polt.

Mallards(Anas platyrhynchos) and Green-Winged Teal(anas crecca) were studied at Kum River, Kongju, Korea, from 29, December, 1990 to 5, Janury, 1991. There was a wide difference between Mallards(Anas platyrhynchos) and Green-Winged Teal(Anas crecca) in body length but used to same Resting or Feeding area. Resting time was the major activity of mallards(43-45%) and Feeding time was the major activity of Green-Winged Teal(30-34%). Both species increased Resting time as approach of sunset but Locomotion and Comfort decreased. Locomotion(22-24% and 16-24%) and Comfort(16-21% and 14-22%) also were dominant behavioral activities of Mallards and Green-Winged Teal, respectively. Total time spent in Alert, Courtship and Agnoistics behavior was low for both species(>3%). Mallards and Green-Winged Teal rested most on sand bar in River side, while paddy fields were used most for feeding area.

韓國의 흑두루미 Grus minacha Temminck의 越冬生態에 關한 硏究

趙三來,元炳旿 경희대학교 한국조류연구소 1990 연구보고 Vol.3 No.-

The census, food habitat, carrying capacity, energy budgets and time budgets of Hooded cranes(Grus monacha were studied from October 1987 to March 1990 in Korea. Population food and foraging habitat requirements with availability were investigated and compared among 4 wintering areas. About 200-300 population of the Hooded cranes wintered or staged on the paddy fields of western Taegu region from late October to middle February. Waste rice grain in harvested paddy fields was the primary food and the main source of Hooded cranes during the period of their winter and spring migration. Hooded cranes ate >98% rice grains in paddy fields and ate <1% plants tubers and vegetables in upland fields. Time and energy budgets were quantified for the Hooded cranes' wintering behavior in western Taegu region. The Hooded cranes spent more time on gleaning in November(p<0.01) and more time on probing in February(p<0.01). Juveniles spent more time on searching, gleaning, probing and locomotion than adults (p<0.01). In 1989-90, the Hooded cranes spent more time on probing(p<0.01) and less time on gleaning and resting than other years(p<0.01). There were many different kinds of stimuli causing disturbance in cranes. They might be moving objects such as men, cars, cultivators, motor cycles, or running dogs and immovable obstructions to open view such as trees, mountains, green houses and electric transmission towers, etc. Among these the most prominent disturbing stimulus seemed to be men. The mean density of waste rice grain deceased from 3.52g dry wt/㎡ in October to 2.08g dry wt/㎡ in March after the departure of the Hooded cranes(p<0.05). The amount of rice grains necessary to meet daily food requirements was quantified for each wintering area to assist managers in determining carrying capacity of the Hooded cranes and availablity of adequate food supplies besed on crane-use days. Therefore, rice availability of this area is unlikely to affect 400-450 Hooded cranes' use of the wintering areas unless cropping practices or fall tillage reduce the areas of harvested paddy fields. These cranes should be not only preserved but also properly administered with such facilities as feeding stations which artificially provide food which will supplement the lack of natural food in the wintering period for the long-term conservation of the endagered cranes which are natural monuments for all human beings. Accordingly, this area should be strictly prohibited and prevented from environmental devastation and contamination for the wintering ground of Hooded cranes.

The purpose of this study was to investigate an influence of the change of central panoramic curves on the image reconstruction in the dental implant CT. The author designed three experimental groups according to the location of central panoramic curve. In group A, central panoramic curve was determined as the couve connecting the center of roots from the first premolar to the first molar. In group B, central panoramic curve was determined as the line connecting the lingual cortical plate at the level of the mesial aspect of the first premolar with the buccal cortical plate at the level of the mesial aspect of the first molar. In Group C, central panoramic curve was determined as the line connecting the buccal cortical plate at the level of the mesial aspect of the first premolar with the lingual cortical plate at the level of the mesial aspect of the first molar. Twenty four reformatted CT images was acquired from four mandibles embedded in the resin block and twenty four contact radiographs of dog specimens were acquired. Each Image was processed under Adobe Photoshop program analysed by MSPA (mandible/maxilla shape pattern analysis) variables such as MXVD, MXHD, UHD, MHD, and LHD. The obtained results were as follows; 1. The mean of MXVD variable was 19.9, 20.2, and 20.0 in group A, B, and C, respectively, which were smaller than actual value 20.5. But, there was no significant difference among 3 groups(P>0.05). 2. The mean of MXHD, UHD, MHD, and LHD variables in group A,B,and C was 11.9, 12.2, and 12.3; 9.3, 9.5, and 9.6; 10.0, 10.3, and 10.3; 9.2, 9.3, and 9.4 respectively which were equal to or greater than the actual value 11.8, 9.3, 10.0, and 9.2, But, there was no significant difference among 3 groups (P>0.05). 3. The number of noneffective observations with difference over or under 1 mm with comparison to the actual value was 24(20%), 58(48.3%), and 52(43.3%), respectively, in group A, B, and C. 4. In group A, the number of observations over 1 mm and under 1mm was 9 and 15, respectively, but in group B and C, the number of observations over 1 mm was more than under 1 mm.

박태원,유동수,최항문,이삼선,박래정,최순철 大韓口腔顎顔面 放射線學會 1998 Imaging Science in Dentistry Vol.28 No.1

We used five adult dog mandibles embedded in resin block and six different cross-sectional planes for each mandible were choosen. According to the angle of mandibular occulsal plane to vertical plane(mandibular angle)and gantry angle of CT machine, we classified 4 experimental groups and 1 control group. The control group images were taken at the mandibular angel 0˚and gantry angle 0˚. The experimental images were taken at the mandibular angle 15˚and gantry angle 0˚(group 1);30˚and 0˚(group 2);15˚and 15˚(group 3);30˚and 30˚(group 4), respectively, Using the reformatted cross-sectional images, the distance from the mandibular canal to the alveolar crest and the distance from the mandibular canal to the buccal cortex and to the lingual cortex was measured and compared. The obtained results were as follows; 1. The distance from the mandibular canal to the alveolar crest of group 1 and 2 was larger than control group, but the distance of group 3 and 4 was smaller. The distance from the mandibular canal to the buccal cortex and to the lingual cortex of all experimental groups was smaller than control group. 2. The distance from the mandibular canal to the alveolar crest showed the largest difference from control group in all experimental groups, especially in group 2 and 4(p<0.05)> 3. In the distance from the mandibular canal to the alveolar crest, the number of deviation value under 1mm was 20 in group 3 and was 11 in group 2 and 4, respectively. 4. The deviation value of the distance from the mandibular canal to the buccal cortex and to the lingual cortex was under 1 mm in most cases.
