The variances of atomization characteristics with the misalignment of injectors defined as the fraction of skewness for various angles of impingement and pressure conditions were studied using the doublet impinging injectors with a like-on-like arrangement. Water was used as simulant and the spray characteristics along with the changes in the skewness were analyzed using the methods of spray image photography. Experiment was carried for the impinging nozzles of orifice diameter of 1.2 mm within Reynolds numbers ranging from $9{\times}10^3-4.5{\times}10^4$ and the fraction of skewness considered for the experiment ranges from 0.0 to 0.9 at ambient temperature condition. Flat sheet with a distinct rim produced perpendicular to the plane of impinging jets goes ondisappear and sheet appears comparatively shorterwith the increase in fraction of skewness resulting the atomization of fluid droplet very close to impingement point with decrease in breakup length and increase in spray angle up to certain extent. The maximum allowable skewness was found as the result. The skewness up to the certain extent can be considered as the parameter to control the atomization characteristics of simulant inside the combustion chamberproviding the high economic performance of fuel and time.

Post-stroke spasticity is a common complication that can be deleterious to the daily living function and quality of life of stroke survivor. This case report was conducted to introduce the use of miniscalpel-acupuncture as a novel method for the treatment of post-stroke spasticiy in three patients with chronic stroke. Patients received miniscalpel-acpuncuture treatment for 4~7 session. The flexor digitorum brevis, pronator teres, pronator quadratus, brachioradialis, tibialis posterior, gastrocnemius on the affected side were needled. The main outcome were the Modified Ashworth Scale (MAS) muscle spasticity score and the range of motion. The evaluation indices were measured after the initiation of treatment and after treatment. After miniscalpel-acupuncture session, three patients improved as indicated in the MAS grade and range of motion. This retrospective case report presents miniscalpel-acupuncture as a potentially effective approach in Korean medicine rehabilitation treatment of post-stroke spasticity. Further research is needed to confirm these findings.

The present study was investigated the oviposition characteristics of Protaetia brevitarsis seulensis with a focus on winter larvae to improve the utilization of insect resources. The average oviposition tendency and average cumulative number of eggs laid during a 7-week period were measured in adults emerging from larvae that had hibernated for 4 months in five farmhouses. The study covered five zones: Gimje, Jangsu, Wanju, Iksan and Yeoju. The average oviposition tendency over a 7-week period showed increased egg laying between 2 to 3 weeks and 5 to 6 weeks. Overall, it was found that the average cumulative number of eggs laid during the 7-week period was initially low and increased proportionally with time. Our results suggest that using adults that have emerged from hibernated larvae is effective in increasing the oviposition rate and utilization of the insect.

In recent years, South Korea has often witnessed damages by gusts caused by thunderstorms in summer. The Korea Meteorological Administration defines that a gust happens when the maximum instantaneous wind velocity is 10m/s or more and draws up hourly observation reports. When a cumulonimbus develops due to an ascending current and reaches the height of 12~16 km, the temperature of the cloud top drops and a lightening happens, which causes a gust accompanied by a thunderstorm and further regional meteorological damage. It's difficult to predict a regional gust with the mesoscale prediction model at the administration. Thus this study set out to analyze the damage cases by a gust accompanied by a thunderstorm and to make a contribution to the prediction and understanding of a gust by a thunderstorm. A gust by a thunderstorm happens where potential equivalent temperature converges or is higher than the surrounding areas. The convergence area of potential equivalent temperature matches the track of thunderstorm cells. The Kimje gust took place where high potential equivalent temperature converged, and the Jangsu gust did as the area of high potential equivalent temperature approached. There should be a good amount of vapor supply with the moisture flux converging at the bottom layer in order to bring instability. In addition, it should collide into a dry and cold atmosphere at 700 hPa. The moving track at the center of the low dew point spread corresponds to that of a gust.
