Purpose : This study evaluated the effects of transcranial direct current stimulation and a virtual reality program on the depression, hand functions, cognitive function, and activities of daily living of patients with mild cognitive impairment by dividing 20 patients with mild cognitive impairment and depression. The 20 patients were divided into a treatment group (transcranial direct current stimulation + a virtual reality program) and a control group (placebo transcranial direct current stimulation + a placebo virtual reality program). Methods : This study allocated ten subjects to the treatment group and ten subjects to the control group. The treatment was given five times per week for six weeks (30 sessions), and each session was 30 minutes. This study screened depression by using SGDS-K, a short geriatric depression scale, to examine depression before and after treatment intervention. This study also used the box and block test, NCSE, and FIM to evaluate hand functions, cognitive function, and activities of daily living, respectively. Results : The results showed that depression significantly decreased, hand functions significantly increased, cognitive function significantly improved, and activities of daily living significantly increased after intervention in the treatment and control groups. The magnitude of changes in depression, hand functions, cognitive function, and activities of daily living was significantly different between the two groups after intervention (p>.05). Conclusion : The results showed that the application of transcranial direct current stimulation and a virtual reality program could improve cognitive function, hand functions, and activities of daily living by decreasing depression. Therefore, it can be concluded that the simultaneous application of transcranial direct current stimulation and a virtual reality program is an intervention method, which can be applied for decreasing depression, enhancing hand functions, improving cognitive function, and increasing activities of daily living in patients with mild cognitive impairment.

The purpose of this article was to review the changes in translucency of direct esthetic restorative materials after curing, aging and treatment. As a criterion for the evaluation of clinical translucency changes, visual perceptibility threshold in translucency parameter difference (${\Delta}TP$) of 2 was used. Translucency changes after curing were perceivable depending on experimental methods and products (largest ${\Delta}TP$ in resin composites = 15.9). Translucency changes after aging were reported as either relatively stable or showed perceivable changes by aging protocols (largest ${\Delta}TP$ in resin composites = -3.8). Translucency changes after curing, aging and treatment were perceivable in several products and experimental methods. Therefore, shade matching of direct esthetic materials should be performed considering these instabilities of translucency in direct esthetic materials.

This experiment was conducted to evaluate effects of wilting and additives on fermetation characteristics, quality and aerobic stability of silage of rye(Seca1e cereale L.) harvested at the early heading stage. Harvested rye was wilted or mixed with beet pulp and then treated with formic acid or lactic acid bacteria(LAB) inoculant. Treatments were consisted of direct cut(DC), wilted(WT), beet pulp added(BP), direct cut and formate applied(DF), wilted and formate applied(WF), beet pulp and formate applied(BF), direct cut and LAB inoculated(DL), beet pulp added and LAB inoculated(BL), and wilted and LAB inoculated(WL) silages. Afler 70 days of ensiling period, the silages were opened and exposed to air for 7 days, and the silages of opening day(0 day) were compared with the silages exposed to air for 7 days(7 day). 1. LAB inoculated rye silages(DL, WL, BL) lowered pH values effectively eom the third day of ensiling and showed most stable pattern of pH changes during the initial fermentation process. Direct cut and formate applied(DF), beet pulp and formate applied(BF) and beet pulp added(BP) silages were also effective in lowering pH from the seventh day thai direct cut treatment(DC). 2. pH was low below 3.7 in all treatments of 0 day. After 7-day period of aerobic exposure, DL and WL showed considerable increases in pH from 3.5 and 3.4 to 8.3 and 6.4, respectively. 3. Direct cut rye silages(DF, DC, DL) and beet pulp and formate treatment(BF) produced effluent of 121.2, 85.9, 80.3 and 34.2 mlkg, respectively and these were greater than others(P<0.01). Beet pulp retained 1.61 I/kg of effluent at the application rate of 50 kg/t in comparing BP with DC, and formate application increased the amount of effluent in comparing DF and BF with DC and BP, respectively(P<0.01). 4. Beet pulp and LAB treatment(B1) was highest in content of lactate as 3.1% and formate treated silages(DF, WF, BF) showed lower content of lactate and total acid than others. LAB inoculated(D1, WL, BL) and wilted (WT) silages were graded to be good quality as a second group by the Flieg's score. Formate applied silages (DF, WF, BF) were graded as a foum group lower than DC by one. 5. Residual content of WSC of rye silage was higher in BP, BF, DL and BL than direct cut treatment(M3) (P< 0.01). Formate application had a tendency to increase the content of residual content of WSC. 6. For the ratio of NH3-N to Total N, wilted and LAB inoculated(W1) and direct cut and LAB inoculated(D1) silages were lowest on 0 day as 8.9 and 9.3% respectively. But after 7-day period of aerobic exposure, WL and DL showed largest increase of the ratio of $NH_3-N$ to Total N from 0 day(P<0.01). 7. On 0 day wilted(WT), beet pulp and formate treatment(BF), and beet pulp and LAB treatment(B1) were lower than direct cut treatment(DC) for NDF and ADF concentrations consistently. Formate applied silages (DF, WF, BF) made little change in ADF and NDF concentrations during 7 day period of aerobic exposure. DL and WL showed a large increase in ADF and NDF concentrations under aerobic condition(P<0.01). 8. IVDMD values of wilted(WT), beet pulp added(BP), wilted and LAB inoculated(W1) and beet pulp added and LAB inoculated(B1) silages were higher than direct-cut treatmentPC) as 84.7, 84.7, 84.4 and 83.0%, respectively on 0 day. But during 7-day period of aerobic exposure, a great decreae in IVDMD of WL was showed(P<0.01). The experimental results indicate that wilted silage(WT) could be recommended as the most effective treatment for reducing efluent and increasing quality and feed value of rye silage without deteriorating aerobic stability more than direct cut treatment(DC). Additionally, under unfavorable weather condition beet pulp added and LAB inoculated treatment(T3L) might be the possible alternative for successful ensiling of forage rye.

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation method that delivers 1-2 mA of current to the scalp. Several clinical studies have been conducted to confirm the therapeutic effect of major depressive disorder (MDD) patients with tDCS. Some studies have shown tDCS's antidepressant effect, while the others showed conflicting results in antidepressant effects. Our aim of this review is to understand the biological bases of tDCS's antidepressant effect and review the results of studies on tDCS's antidepressant effect. For the review and search process of MDD treatment using tDCS, the US National Library of Medicine search engine PubMed was used. In this review, we discuss the biological mechanism of tDCS's antidepressant effect and the existing published literature including meta-analysis, systematic review, control trial, open studies, and case reports of antidepressant effects and cognitive function improvement in patients with MDD are reviewed. We also discuss the appropriate tDCS protocol for MDD patients, factors predictive of response to tDCS treatment, the disadvantages of tDCS in MDD treatment, and side effects.

Cotton fiber and NaOH-mercerized cotton fiber had been treated by liquid ammonia and were dyed with two direct dyes, C.I. Direct Red 2 and Blue 1. The effect of the treatment on the rate of dyeing, dye adsorption isotherm, and affinity were studied. The rate of dyeing was increased in the order of NaOH-mercerized> NaOH/liquid ammonia-treated > liquid ammonia-treated>Untreated cotton irrespective of kind of dyes. The rate of dyeing for NaOH-treated fiber considerably increased, whereas liquid ammonia-treated or NaOH/liquid ammonia-treated did not because the structural transformation was not enough for the dyes to penetrate easily into the liquied ammonia-treated cottons. The time of half-dyeing was considerably reduced by mercerizing with NaOH, but lengthened by liquid ammonia treatment because of increased equilibrium dye exhaustion especially in dyeing with C.I. Dierect Red 2. In spite of a short time of the ammonia treatment for 4 seconds, the equilibrium exhaustions of both of direct dyes, C.I. Direct Red 2 and C.I. Direct Blue 1, were increased in proportion to internal volume of treated cotton under a condition of fixed affinity.

This is a study through survey with the purpose of analysing of treatment cost for arthritis. Treatment cost can be devided Into two characteristics, one is the direct cost and the other is the indirect cost. Direct cost contains fees of medical treatment Including cost of self treatment & purchsing price of herb durg. On the other hand indirect cost means the using money of tansportation, lodging charge & labor-losing-time cost. For the succession of medical treatment of chronic diseases patients have to control themselves to go shopping around for the cure remeadies. And also it is important that the cost for unefficient or probably hamful folk remeadies should be reduced in order to distribute appropriatively the limited financial resources. As the result of this study, the fees for self treatment & herb drug are two times as much as those of regural medical treatment. Within the direct cost, there are the mean cost of regural medical treatment 59,630 won/mon., self-treatment 42,790 won/mon., and herb drug 78,380won/mon. therefore total mean direct cost is 180,800won per month. Moreover patients intermittently pay the cost of prostheses If folk remedies, these are added to the direct cost as above mentioned. Attributes of folk remedies are various from cure & analgesics to nutrients and their virtues as medicine are not clear in view of scientific knowledge. But 56% of arthritis patients have ever been experienced folk remedies. the cost for these remedies has wide ranges from 40,000 won to 1,000,000won. Total mean indirect cost including the transfortation fee, lodging charge & labor-losing-time cost has the range from 82,825won/month to 106,150won/month. Among these cost, labor-losing-time cost has a mojority because the waiting times are too long for seeing a doctor. In conclusion those patients having arthritis have a large burden against the treatment cost for continuous care. Therefore health professional should make effort to guide the patient to determine themselves informed choice about the treatment process.

This study was carried out to investigate a heat treatment condition and suitable drying schedule of bamboo material(Phyllostachys nigra var. henonis) for a vertical flute with small-notched bamboo. It is very important to prevent drying defects during its drying process. We investigated the effort of heat treatment the most suitable drying schedule for small-notched bamboo vertical flute without drying defects in this research. A direct heat treatment method and drying conditions of 3($20^{\circ}C$ 65%, $40^{\circ}C$ 40%, and dry at air condition) were applied to the Bamboo specimen that felled in several areas for a month. The result suggested that the most suitable drying schedule with the less split and the shortest time was to dry at $40^{\circ}C$, 40% condition and it was useful to direct heat-treatment because of reducing the number and size of split during drying bamboo.

Cotton fabric md nylon fabric were chosen as base fabric specimens for dyeing using Japanese pagoda tree colorants through chitosan, treatment. With the chitosan treatment, the dye-uptake of the treated fabric increased. This treatment is also expected to be effective in terms of environment-friendliness. The effect of the dyeing methods, mordanting or non-mordanting, and chitosan treatment on the dye-uptake and air permeability of the treated fabrics was investigated. In case of cotton fabric, Al mordanted dyeing resulted in higher dye-uptake through the chitosan treatment. Therefore, the chitosan treatment is effective in this case. Japanese pagoda tree seems to have direct affinity for nylon fabric without the mordanting treatment. In case of cotton fabric, it seems that the cellulose molecules, colorants, and the chitosan make a complex, thereby reducing the air permeability. In case of nylon fabric, due to the fact the Japanese pagoda tree colorant molecules form direct physical bonding with the nylon molecules, it seems that there is not much of air permeability reduction.
