  • A new standard carnation Dianthus caryophyllus 'Pink Beryl' was bred from a cross of red standard cultivar 'Francesco' and purple standard cultivar 'Saturn' in 1996 at the National Institute of Horticultural & Herbal Science. After investigation of the characteristics for 4 years from 1997 to 2000 and registered to the official breeding variety of Rural Development Administration in 2000. 'Pink Beryl' is pink standard cultivar with round edge of petal for cut flower. It has medium resistance to Fusarium wilt. To avoid calyx splitting caused by high temperature, this cultivar is recommended to grow over $8^{\circ}C$ at night and under $25^{\circ}C$ at days during flower bud differentiation period.

  • Currently, the operation rule of agricultural reservoirs in case of drought events follows the drought forecast warning standard of agricultural water supply. However, it is difficult to preemptively manage drought in individual reservoirs because drought forecasting standards are set according to average reservoir storage ratio such as 70%, 60%, 50%, and 40%. The equal standards based on average water level across the country could not reflect the actual drought situation in the region. In this study, we proposed the improvement of drought operation rule for agricultural reservoirs based on the percentile approach using past water level of each reservoir. The percentile approach is applied to monitor drought conditions and determine drought criteria in the U.S. Drought Monitoring (USDM). We applied the drought operation rule to reservoir storage rate in extreme 2017 spring drought year, the one of the most climatologically driest spring seasons over the 1961-2021 period of record. We counted frequency of each drought criteria which are existing and developed operation rules to compare drought operation rule determining the actual drought conditions during 2016-2017. As a result of comparing the current standard and the percentile standard with SPI6, the percentile standard showed severe-level when SPI6 showed severe drought condition, but the current standard fell short of the results. Results can be used to improve the drought operation criteria of drought events that better reflects the actual drought conditions in agricultural reservoirs.

  • The purpose of this study is to do the Somatotype classification according to the type of shoulder-neck and to give the thinkness of shoulder pad according to them. Therefore this study was measurement body size of 201 and the somatotypes were classified as their plumb line. The standard somatotype of this measurement was classified as 9 type according to its angle of shoulder inclination and neck length. Pads which have different thickness (1 cm, 1.5 cm, 2 cm) were attached to the 9 body type and the set-in sleeve blouse and raglan sleeve blouse were made and tring test and sensory test were accomplished. The results of this study were as follows: 1 . Classification of shoulder-neck relationship. Angles of shoulder inclination ($15^{\circ},\;21^{\circ},\;27^{\circ}$), lock lenaths (10 cm, 12.5 cm, 15 cm) were classi- fied as 3 type each and these types were combined as 9 types. II . The result of angle difference of shoulder inclination according to pad thickness. 1) In case of set-in pad. angle is increased $5.75^{\circ}$ per 1 cm of pad thickness. 2) In case of raglan pad. angle is increased $6.45^{\circ}$ per 1 cm of pad thickness. III. The most fit pad thickness to the 9 types. In case of set-in sleeve blouse. 1) High shoulder-long neck, Standard shoulder-long neck Low shoulder-long neck, Stan-dard shoulder·standard neck. Low shoulder-standard neck: 1.5 cm. 2) High shoulder-standard neck, Standard shoulder-short neck, Low shoulder-short neck: 1 cm. 3) High shoulder-short neck: 0 cm(without pad) In case of raglan sleeve blouse. 4) High shoulder-long neck, Standard shoulder-long neck, Low shoulder·long neck, Stan-dard shoulder-standard neck, Low shoulder-standard neck: 1.5 cm. 5) High shoulder-standard neck, Standard shoulder-short neck, Low-shoulder-short neck: 1 cm. 6) High shoulder-short neck: 0 cm(without pad)

  • This study was conducted to investigate nursing students' safety-climate: perception and performance of standard precautions for healthcare-associated infection control. We also identified actors influencing performance of standard precautions. Data were collected from 246 junior and senior nursing students at nine colleges in D city from July to September, 2016. The mean score of performance was significantly lower than that of perception in all areas of standard precautions. The biggest difference between perception and performance was in the usage of personal protective equipment and safe injection practices. We also detected significant positive correlations among safety-climate, perception, and performance of standard precautions. In the regression analysis, performance of standard precautions was influenced by safety-climate and grade accounting for 10.7% of variance. To improve healthcare-associated infection control among nursing students, safer and more supportive practical environments need to be provided, and new training strategies such as simulation education need to be expanded.

  • The author studied the magnification ratio of teeth length in orthopantomogram through intraoral film taken by standardized paral1eing technique. In this study, intraoral radiograph and orthopantomogram were taken in 2 cases of dry skull and 36 adults (504 teeth). 1. The obtained results were as follows: In case of dry skull, the magnification ratio of standard films was 4.6% to 5.9% and that of Orthopantomograph 5 was 15.1% to 33.1%. The magnification ratio of to the standard film was 9.2% to 26.5% 2. In case of adults, the magnification ratio of Orthopantomograph 5 to the standard films was 9.5% to 24.6%. 3. There were no significant difference in magnification between left and right. 4. Anterior teeth had lesser magnification than posterior teeth. 5. It was considered that teeth length showed in Orthopontomograph 5 was magnified 15.4% to 31.3% than actual teeth length.

  • A national standard system for the petroleum field has been developed to calibrate and test the oil flow meters in Korea. The operating system and the uncertainty of the system were evaluated by the peer reviewers of foreign national metrology institutes in 2002. Since the characteristics of the system might be changed by time, the uncertainty of the system is reevaluated with the consideration of the long term stability of the system. It is found that the system has a relative expanded uncertainty of 0.048 $\%$ in the range of $15\~120\;m^3/h$. According to the uncertainty budget, the uncertainties of the fluid density and the final mass measurement, which are temperature dependent, contribute about $94\%$ of the total uncertainty in the oil flow standard system

  • Green Standard for Energy and Environmental Design (G-SEED) is evaluates the eco-friendliness of the building as an abjective means. Study in green building is made actively, and is being developed through constant revision. However, study results of green building have not been fully reflected in the standard. Therefore, this study analyzes the previous studies about G-SEED and checks the reflection of requirements. This study will be a reference of future revision of G-SEED. Score of items are divided into low and high score items. These items should be reflected appropriately in the standard through the score adjustment. Some requirements proposed in previous studies was reflected, while substantial requirements was not reflected. Proposed improvement requirements are classed as to establish specific standards, strengthen standards, propose a new evaluation method to existing items, and add new items.

  • The aims of this study are to evaluate the measurement capability of the electromagnetic power and to understand the current state of standard maintanance of the eight participants among the thirteen national calibration and test organizations. The calibration factors were measured at six test frequencies, 50, 100, 500, 1000, 5000, 10000 MHz by organizations and KRISS on the basis of round robin test. The results were analyzed by calculating the standard deviation of the measured values from the standard values. The analysis shows good agreement within 1.0% for all participants at the measurement frequencies. Therefore, the measurement capability of all participants is good in the frequency range of 50 MHz to 10 GHz. For the four participants which specified standard deviations of repeated measurements in their reporst, the total uncertainties is less than 1.9% at the measurement frequencies.
