BACKGROUND: This experiment was conducted to examine the effects of organic Se concentration and the number of foliar applications on growth characteristics and Se content in rice. METHODS AND RESULTS: A series of multiple foliar applications were performed at (1) 3 times (maximum tillering stage + booting stage + heading stage), (2) 4 times I (effective tillering stage + maximum tillering stage + booting stage + heading stage), (3) 4 times II (maximum tillering stage + booting stage + heading stage + grain filling stage) according to the development stage. Each set of the foliar application plots was treated with 0, 10, 20, 40, 60, 100 ppm of Se and with mixed pesticide ($P^*$ + Se 40 ppm) in which the treatment time was the same as that of the treatment 4 times II. The total cultivation period of rice was 184 days. Se contents in rice (brown rice, white rice) were analyzed by ICP. CONCLUSION: The number of grains per head tended to decrease with increasing concentrations of organic Se in all treatments. However, number of panicles per hill did not show statically significant differences between the 3 times and 4 times I treatments. The grain yield decreased with the 3 times and 4 times II, but there was no significant difference in 4 times I. Se content in brown rice was the highest at 100 ppm Se (5268.64) treatment and lowest at 10 ppm Se ($1269.19{\mu}g{\cdot}kg^{-1}$) treatment. Se content in the polished rice was the highest at 100 ppm Se (5047.33) treatment and lowest at 10 ppm Se ($885.05{\mu}g{\cdot}kg^{-1}$) treatment. The higher selenium was treated, the higher Se content was found in the rice (brown rice, polished rice).

A phenylbenzimidazole derivatized sensor (L) that behaves as a ratiometric fluorescent receptor for $Zn^{2+}$ in water has been described. In HEPES buffer at pH 7.4, sensor L displays a weak fluorescence emission band at 367 nm. Upon addition of $Zn^{2+}$, the emission intensity at 367 nm is decreased, concomitantly, a new emission band centered at 426 nm is developed, thus facilitates a ratiometric $Zn^{2+}$ sensing behavior. Sensor L binds $Zn^{2+}$ through a 1:1 binding stoichiometry with high selectivity over other metal cations. Sensor L displays a linear response to $Zn^{2+}$ concentration from 0 to $6.0{\times}10^{-5}M$, sensor L also exhibits high sensitivity to $Zn^{2+}$ with a detection limit of $3.31{\times}10^{-7}M$.

Time-concentration curves of recombinant human interferon alpha$(rIFN-{\alpha}A)$ in the skin and serum of nude mice or rats were studied after topical application of IFN ointment. IFN appeared in the skin and serum in less than 30 minutes and lasted for more than 10-12 hours at high concentration level after the application to nude mice at a dose of $9.0{\times}10^5\;IU/g$ mouse. But in the rats, IFN was not detected in the serum even 7 hours after the application at a dose of $6.0{\times}10^5\;IU/g$ rat. Topical application of IFN might be useful for the topical and systemic treatment if the human skin resembles that of nude mouse in respect to transport characteristics.

PURPOSE: This study was conducted to investigate the effects of Kinesio taping and massage application to the calf muscles on ankle stability. METHODS: The study subjects were 66 healthy adults (male: 32, female: 34) who had no instability in their ankles. Subjects were randomly assigned to a Kinesio taping group or a massage group. The research tool used the Y-balance test to measure instability of the ankle. The distance between the right and left foot was measured from the center in the anterior, posterior-medial, and posterior-lateral directions. Massage was applied to the calf muscles three times over two weeks and Kinesio tape was attached to the calf muscle and tibialis anterior for 10 hours twice during the experimental period. RESULTS: The results showed that application of Kinesio taping resulted in increases in the distance between the feet increased in some directions. After the massage, the distance extended from the anterior and posterior-lateral directions was prolonged, and the ankle stability on the right and left sides was partially improved by massage application. CONCLUSION: Kinesio taping and massage applied to the calf muscles are appropriate interventions for the improvement of ankle stability. Based on the application times of massage, Kinesio taping appears to work more effectively for ankle stability.

The purpose of this study was to examine the application tendency of the western classical style which appears in contemporary performing arts centers. The types of space in performing arts centers were investigated according to the times. There were somewhat fixed stage and auditorium types for each period ; the ancient times had the arena stage and round auditorium, the Renaissance the proscenium stage and the U-shaped auditorium, the Elizabethan period the thrust stage and polygonal auditorium, and the modern times the proscenium and apron stage, the horseshoe and fan type auditorium. Today since the purposes of performance are multiple, a variety of stage types are applied to each performing arts center. They use various spaces and performances of multiple purposes by moving and transforming the stage and auditorium according to the kinds of performance as a variation of the arena and proscenium stage. Recently there appear complex performing arts centers that can plan performing spaces of diverse sizes and forms to fit the functions of a performance in a large building. Since they put on performances in a large space according to the characteristics of the kind of performance, the intentions and goals of the performance are well delivered to the audience.

For continuous laser micro patterning on three-dimensional free form surface, innovative laser system is developed. The two axis galvanometer is combined with the dynamic focusing unit to increase optical distance. Also, it is synchronized with the 3 axis mechanical system. To determine laser machining sequence, laser CAM system is developed. It can make possible of 3D surface micro patterning under $25{\mu}m$ pattern width. The uniformity of pattern width is about 2.8% and it is validated that focal plane is well conserved by the dynamic focusing unit. Velocity and positional information of 1 axis is stage is fed to the scanner control board by the encoder signal and it makes possible real time synchronization. With this system, possible patterning volume is enlarged from $40{\times}40mm^2$ to $40{\times}120{\times}30mm^3$.

A novel electrochemical potentiostatic method has been examined in order to enhance the hole concentration of p-type GaN thin films using KOH and HCl electrolyte. The hole concentration was increased more than 2 times by the electric voltge apply with the mobility of $10{\sim}12cm^2/V.s$. At optimum condition of 3V apply, hole concentration was enhanced more than reference sample from $1.7{\times}10^{-17}cm^{-3}$ to $4.1{\times}10^{-17}cm^{-3}$. Application of this activation method to blue-LED fabrication improved optical output from 18.4mW to 20.6mW, that is ~12% increase. SIMS analysis indicates that nearly 70% of hydrogen atoms could be removed by this method.

This experiment was carried out to study the effects of planting density and amount of fertilizer applied on the morphological, physiological and physical characteristics of barley culm. The results are summarized as follows: 1. Heavy application of fertilizer increased the diameter of the inside and outside thickness of culm, dry weight per unit culm, culm length, spike weight and number of per hill. 2. Thined planting density increased lodging resistance. But lodging resistance in sparse-planted plot of$20{\times}$ 20cm was almost the same as that in the plot of $15{\times}$ 15cm. 3. In the heavy fertilized plot weight of culm at breaking, bending moment of culm atbreaking, secondary moment of inertia and section modulus increased more than those in the standard fertilized one. As a result heavy application of fertilizer gave high lodging resistance. On the other hand thined planting density increased the above-mentioned physical characters of culm. 4. In the case of dense planting lodging index became higher in standard fertilized plot, but in the case of sparse planting over 10 x 10cm there were no significant differences in lodging index as affected by amount of fertilizer applied and planting density. 5. Grain yield was increased by heavy application of fertilizer and proper planting density was $5{\times}$ 5cm or $10{\times}$10cm for the safe maximum yield.

Performance of the mobile devices greatly depends on the efficient resource management because they are usually resource-restricted. In particular, the dynamic storage allocation algorithms very important part of the mobile device's operating system and OS-like software platform. The existing dynamic storage allocation algorithms did not consider application's execution style and the type, life-time, and characteristics of memory objects that the application uses. Those algorithms, as a result, could not manage memory efficiently Therefore, this Paper analyzes the mobile application's execution characteristics and proposes anew dynamic storage allocation algorithm which saves the memory space and improves mobile application's execution speed. The test result shows that the proposed algorithm works 6.5 times faster than the linked-list algorithm[11], 2.5 times faster better than the Doug. Lea's algorithm[12] and 10.5 times faster than the Brent algorithm[14].
