This work was carried out to investigate growth characteristics of the underground water-treated strawberry by different type of film and pot size. The flower bud differentiation of ‘Maehyang’ was taken 27 days after treatment of cold water curtain and 8 hours short-day. Among ‘Maehyang’, ‘Nyoho’ and ‘Akihime’, ‘Maehyang’ and ‘Nyoho’ needed same days for the flower bud differentiation, whereas ‘Akihime’ needed fewer days than the others. Also ‘Maehyang’ and ‘Akihime’ reguired same days for the flower bud development. The white & black plastic film in addition to silver color plastic film were helpful for the flower bud differentiation by short-day condition than the only black plastic film because they kept the low temperature at night. Flower bud differentiation were promoted by pot seedling than that of non-provisional temporary planting. The optimal pot size were 100 mL and 115 mL volumed pots which shows satisfactory root development.

Real Time Kinematic GPS will allow a multitude of monitoring, navigation and engineering applications. Applications inclued real time deformation and movement monitoring and real time automated plant control. In a low dynamic environment, with a short baseline length, it is possible to position a roving receiver to an approximate accuracy of less than 5mm within a few seconds of thestart of the ambiguity. One Engineering application is the monitoring of the movement of cable suspension bridges. Such structures are capable of movements of up to a few meters under adverse wind conditions or heavy traffic loads. The use of relative OTF positioing at strategic points upon the bridge would allow close monitoring of the bridge's movements and calculate deformation and long-term deterioration factors for the bridge. Future bridge designs and traffic management schemes could also benefit from the monitoring system.

The cadastral administration is centered around cadastral maps. It increasing that demand of the public for effective administration and higher quality of service through the development of application program of cadastral maps maintenance. Also, there has been much demands for the digital information of cadastral maps in other systems. Land Information System is the answer to meet with the public for effective administration and higher quality of service. In this study, The graphic and attribute data of cadastral maps were integrated on the same DBMS. Also, pointing out difficulties of database implementation and many experiences in the development of application program will be used effectively for further expansion of the automation of cadastral administration.

Satellite visibility, accuracy, and availability were increased by the combined GPS/GLONASS. But, there are some problems such as differences in the time frame, differences in the coordinate datum, and the problem of solving carrier phase ambiguities in the combined carrier frequency solutions due to different GLONASS frequency. Therefore, the author will access the accuracy analysis of positioning using the combined PGS/GLONASS, and intend to study the characteristics of the combined GPS/GLONASS with considered the rate of data acquisition according to satellite visibility, elevation mask angle and kinematic relative position at the combined GPS/GLONASS.

The aim of our research is to find out how digital photogrammetry responds to image compression. Specially, we wish to know if using JPEG image compression leads to loss of accuracy in DTM derived by digital methods. We first review JPEG compression, and since we use the PCI OrthoEngine Airphoto Edition v6.3 digital phtogrammetry software, we briefly review it's principle of principle of operation. We use knowledge of the effect of JPEG compression on the geometric accuracy of images to predict the influence of compression on DTM accuracy. We then compare this to estimates derived from actual measurements. We find that the actual effect om DTM accuracy is greater than predicted, and consistent with geometric error due to compression in the region of 0.33 pixel.

The blood pressure measuring equipment, which is being supplied and used most widely by being recognized convenience and accuracy now generally, is oscillometric blood pressure monitor. However, a change in blood pressure is basically influenced by diverse elements such as each individual’s physiological status and physical condition. Thus, the measurement of blood pressure, which used single element called oscillation in blood pressure of being conveyed to cuff, is not considered on physiological elements such as cardiovascular system status and blood vessel stiffness index, and on external elements, thereby being quite in error. Accordingly, this study detected diverse bio-signals and body informations in each individual as the measurement subject such as ECG, PPG, and Korotkoff Sound in order to enhance convenience and accuracy of measuring blood pressure in the complex measurement equipment, thereby having extracted regression method for compensation in error of oscillometric blood pressure measurement on the wrist, and having improved accuracy of measuring blood pressure. To verify a method of improving accuracy, the blood pressure value in each of SBP, DBP, MAP was acquired through 4-stage experimental procedure targeting totally 51 subjects. Prior to experiment, the subjects were divided into two groups such as the experimental group for extracting regression method and the control group for verifying regression method. Its error was analyzed by comparing the reference blood pressure value, which was obtained through the auscultatory method, and the oscillometric blood pressure value on the wrist. To reduce the detected error, the blood pressure compensation regression method was calculated through multiple linear regression analysis on elements of blood pressure, individual body information, PTT, HR, K-Sound PSD change. Verification was carried out on improving significance and accuracy by applying the regression method to the data of control group. In the experimental results, as a result of confirming error on the reference blood pressure value in SBP, DBP, and MAP, which were acquired through applying regression method, the results of -0.47±7.45 ㎜Hg, -0.23±7.13 ㎜Hg, 0.06±6.39 ㎜Hg could be obtained. This is not only the numerical value of satisfying the sphygmomanometer reference of AAMI, but also shows the lower result than the numerical value in SBP : -2.5±12.2 ㎜Hg, DBP : -7.5±8.4 ㎜Hg, which is the mean error in the experimental results of Brram’s research for verifying accuracy of Omron RX-M, which shows relatively high accuracy among wrist sphygmomanometers. Thus, the blood pressure compensation could be confirmed to be made within significant level.

This study was conducted to identify quantitative trait loci (QTL) related to grain qualities under high temperature during ripening stage using 187 Korean rice varieties. To analyze grain qualities under high temperature during ripening stage, grain appearance such as head rice and chalky grains percentage and physicochemical characteristics were investigated and SNP genotyping of 187 Korean varieties was conducted for association analysis related with grain qualities under high temperature. Five traits exhibited continuous distributions in the non-glutinous Korean varieties, indicating that these traits are controlled by multiple genes. Association mapping among non-glutinous Korean varieties was conducted using 223 markers showed polymorphism among 384 SNP markers. Six QTLs for chalk grains percentage were mapped to chromosomes 1, 4, 10 and 11. These six QTLs were linked to the SNP marker id1014176 on chromosome 1, id4010924 on chromosome 4, id10000644 on chromosome 10 and id11011505 on chromosome 11, and explained approximately 21, 61, 50, 23, 23 and 21% of the total phenotypic variance. Four QTLs for head rice percentage in chromosomes 4, 10 explained the total phenotypic variance by over 47% and around 20%. Fifteen QTLs for RVA characteristics including hot paste viscosity, peak viscosity and setback viscosity were mapped to chromosome 1, 6, 7, 12 and QTLs were explained around 20% of the total phenotypic variance.
