Background: The appropriate use of drugs is very important for a healthy life, as appropriate medication must be taken correctly for successful treatment of a disease. The purpose of this study was to investigate the self-efficacy between health status and drug abuse behavior. Methods: The subjects of this study were selected from 15 workshops located in Seoul, Incheon, Daejeon, and Chungnam, and, convenience sampling was conducted for each employee between September, 2017 and October 2017. A total of 204 questionnaires were analyzed. The questions evaluated health status, self-efficacy, drug abuse behavior, and general characteristics. Results: First, there was no difference in health status according to the general characteristics of the subjects. The self-efficacy varied according to gender, educational background, and monthly income, but not by marital status and residence area. In addition, drug abuse behaviors differed according to gender, residence area, and monthly income, but not by marital status and education level. Second, drug abuse behavior negatively correlated with health status and self-efficacy. Third, regression analysis showed that the self-efficacy between the health status and drug abuse behavior had a partially mediating effect. Conclusion: In patients with poor health status, it is necessary to increase their self-efficacy to reduce reduce drug abuse. Therefore, regular education programs targeting efficacy and drug knowledge are required in the community.

It may be said that ancient wild Chinese garden had been founded during Qin dynasty and completed through Han, Sui and Tang dynasties. At first used as hunting areas for kings, the ancient resort forests began to take forms of garden. They dug a pond in the garden and made a simulated mountains with the soil that came from the excavations for the pond and suc pavilions has Gyong, Ru, Gak etc. were built around the pond. The ponds were different in size from those in Korea, being of the lake-like size. they made three island in the pond, which were the islands of Taoist hermits with supernatural powers, called Bong-lae, Young-ju and Band-jang respectively. the traditional of making those islands began in the Qin era and were completed in the Han era, being descended to posterity as a traditional garden structure of 'three islands in one pond' garden style. Such style was brought to Korea and first appeared as Kung-Nam-Ji in Back-jae kingdom and then brought to Japan, becoming the tradition of constructing ponds from early Heian era. Those lake-like huge Chinese ponds constituted the core of ancient garden where various feasts took place. Such ponds were also placed at the center of the gardens and played the roles of feasting garden ponds. Through the above-mentioned studies of the ancient Chines garden, the origin of them and the influence of the ancient Chinese ponded garden upon those of Korea and Japan were investigated.

It has been reported that there are many cases of chronic shoulder injuries of golf players, however acute injuries at dominant tide are relatively rare. In this paper, we show a case of acute rotator cuff tears at dominant side due to bad swing in middle-aged woman. We suggest that golfers should be cautious with playing at winter to prevent acute rotator cuff tears by starting with a warm-up and correcting faulty swings.

This study was focused on the use of cationic PAM (Polyacrylamide) as a surface sizing additive to improve the surface sizing properties of paper. Effects of the ionic property, viscosity and charge density of PAM on bending stiffness of surface sized papers were investigated. Use of cationic PAM as a surface sizing additive improved bending stiffness while addition of anionic PAM did not show any effect. Increase of starch holdout with the addition of cationic PAM was attributed as a prime reason of stiffness increase. Viscosity of PAM was one of the most important factors affecting surface sizing due to its influence on the interaction between cationic PAM and oxidized starch solution. Greater improvement of bending stiffness of paper was obtained when high charged PAM was used as an additive. The order of addition was found to have significant influence on the effect of additives since it influences the formation of network structure among starch, cationic PAM, and SA (styrene acrylic acid copolymer). Investigation on the penetration of starch solution was carried out with CLSM (Confocal Laser Scanning Microscopy), and it was shown that the addition of cationic PAM to oxidized starch solution made starch molecules stay on the paper surface rather than penetrating into the paper structure because of the electrostatic interaction between negatively charged fibers and positively charged cationic PAM.

In this study, some of the model verification results of STREAM (Spatio-Temporal River-basin Ecohydrology Analysis Model), a newly-developed hybrid watershed model, are presented for the runoff processes of nonpoint source pollution. For verification study of STREAM, the model was applied to a test watershed and a sensitivity analysis was also carried out for selected parameters. STREAM was applied to the Mankyung River Watershed to review the applicability of the model in the course of model calibration and validation against the stream flow discharge, suspended sediment discharge and some water quality items (TOC, TN, TP) measured at the watershed outlet. The model setup, simulation and data I/O modules worked as designed and both of the calibration and validation results showed good agreement between the simulated and the measured data sets: NSE over 0.7 and $R^2$ greater than 0.8. The simulation results also include the spatial distribution of runoff processes and watershed mass balance at the watershed scale. Additionally, the irrigation process of the model was examined in detail at reservoirs and paddy fields.

Swelling is a body's natural reaction to foot and ankle injury to mount a healing inflammatory response. To some degree, swelling is necessary for healing and is something that cannot be avoided following injury. However, post-traumatic swelling may have an adverse effect on wound healing and surgery can often be delayed due to preoperative swelling. We report on a unique technique of making multiple meshed stab incisions around the site of injury to reduce soft tissue swelling and promote wound healing.

As the minimum feature size decreases, techniques to avoid contamination and processes to maintain clean wafer surfaces have become very important. The deposition and detachment of nanoparticles from surfaces are major problem to integrated circuit fabrication. Therefore, cleaning technology which reduces nanoparticles is essential to increase yield. Previous megasonic cleaning technology has reached the limits to reduce nanoparticles. Megasonic cleaning is one of the efficiency method to reduce contamination nanoparticle. Two major mechanisms are active in a megasonic cleaning, namely, acoustic streaming and cavitation. Acoustic streaming does not lead to sufficiently strong force to cause damage to the substrates or patterns. Sonoluminescence is a phenomenon of light emission associated with the cavitation of a bubble under ultrasound. We studied a correlation between sonoluminescence and sound pressure distribution for the minimum of pattern damage in megasonic cleaning.
