Objectives : The purpose of this research was to find out the efficacy of Castanea crenata Inner Shell (CCIS) on the skin by comparing the difference effect between only MTS (microneedle therapy system) and the CCIS essence application after MTS treatment. Methods : The present author performed once a week and total 3 times of MTS treatment. The treatment time took about 5 ~ 10 minutes and the depth of the needle was adjusted according to the participant's skin condition. In the control group, essence base was applied after MTS and in the experimental group, CCIS powder dissolved essence was applied. One week after each treatment, the change of skin condition was measured. Two weeks after the end of the clinical trial, the skin condition was checked again. Results : In the case of the test group and the control group, there was a significant decrease in thermography temperature and there was a significant increase in skin tone. In the case of pores and pigmentation, there was no significant difference on both group. In the case of moisture, there was a significant increase only in the test group. Conclusion : The MTS treatment itself showed good effects on thermography temperature and skin tone. But in the case of the moisture effect, it was much better when the CCIS essence was applied to the skin after MTS treatment. This study suggests that CCIS essence increases the efficacy of MTS on the point of moisture.

The content of lipid or moisture and index of erythema or melanin on each facial part of 170 urban middle-aged women without dermic disease was measured by non-invasive method. This measurement intended to understand the skin condition on each facial part of middle-aged women, and to determine the correlation between objective measured values and subjective symptom of lipid content/moisture content. The results was summarized as follows. At each facial Part, the order of moisture content was eye rims, forehead, and cheek and that of lipid content was forehead, eye rims, and cheek. The erythema index was in the order oi forehead, cheek and eye rims and melanin index, in the order of eye rims, forehead and cheek. It turned out that the middle-aged women generally lacked lipid content rather than moisture one. The objective measured values of lipid content coincided with subjective symptom of lipid type. The lipid content, erythema index and melanin index showed correlation significantly.

An irrigation scheduling model, IRIS developed to evaluate irrigation demand and irrigation time for upland crops. For IRlS modeling the soil moisture simulation model, SWATRER was adopted and modified. The developed model, IRIS operated under 5 different soil moisture level that is 20%, 40%, 60%, 80% of available soil moisture and optimum soil moisture level, OSML, which is different about the growing stage and no rainfall condition during growing period. As a result for IRIS simulation, irrigation demand for 5 different soil moisture level was 332.3, 409.8, 569.3, 732.2, 539.3mm, irrigation number was 5, 8, 18, 54, 16 times and irrigation interval during peak time of consumptive use was 20, 13, 6, 2, 6 days respectively. It is appeared that the higher soil moisture level the more irrigation demand and irrigation number and the higher soil moisture level the less irrigation interval.

1. Average moisture content of tobacco in BIB silo was about 19: 1% until 4hours conditioned time, and then moisture variation of tobacco after 2hr conditioned was very small. 2. Application of mathematical model for ordering system. 1) The constant K in the exponential equation varies inversely with both relative humidity and equilibrium moisture. 2) Time needed to order blending tobacco leaves with standard moisture from bulking and blending silo was 4 hours. 3) Reconstituted tobacco sheet had higher moisture absorption ratio than Oriental and Burley tobacco. 4) For minimize of conditioning time in BIB silo, the values of K and Mo given in this study can be used in equation(1) to calculate moisture absorption ratio and optimum conditioning time. 3. Average moisture content and water activity of conditioned tobacco for 4 hours in BIB silo was about 20% and 0.65. In this condition. microbial life will inhibite 4. Physical properties of conditioned tobacco in bulking and blending silo for 4hours was virtually no change.

The moisture contents of threshed leaf tobacco during aging storage were very important factor for the improvement or deterioration of leaf quality. Decay and carbonization of leaf tobacco were mainly controlled by moisture contents during storage. The influence of moisture contents on the decay and carbonization of threshed leaf tobacco (Flue-Cured, Var. NC 82. AB3O-1 grade) were examined during 1 year. The moisture contents of leaf tobacco were treated to 3 kg as 12% (controle), 16%, 20% and 24% after redrying, respectively, These tobacco were put into center of carton box containing about 200kg with 12%'s tobacco, and then packed and stored from June, 1988 under natural weather condition in warehouse at Ock-Cheon threshing plant. Samples were taken from dissected carton box at 0, 1, 2, 4, 7 and 12 months after moisture treatment and Racking time, and some chemical properties were investigated at every sampling time. In results of inducement to decay and carbonization of leaf tobaccos during 1 year's storage by moisture treatment. decayed leaf was appeared but carbonized leaf did not. Calorification and decayed leaf occurred at high moisture contents above 20%, and these phenomena were appeared between 30 and 150 days after moisture treatment and packing. High moisture content leaves (above 20%) caused nearby other leaves to be sunk with high moisture content. Nicotine and calcium contents were increased to 20%~30% and 10%~22%, respectively, but total sugar contents was decreased to 40%~60% by moisture treatment(20% ~24% ).

The adsorption of water vapor and equilibrium moisture content(EMC) of the specimens for four softwood species dried by conventional- and high temperature method and equilibrated to 15% of the target EMC condition at 25$^{\circ}C$ were determined by oven drying method and with moisture meters. The amount of adsorption for high temperature dried red pine was significantly higher than that of conventional kiln dried wood, while those of eastern white pine, eastern hemlock and Norway spruce were not significantly different between drying methods. EMCs of these four species determined by oven drying method and with capacitive admittance moisture meter were not significantly different between drying methods. EMC of high temperature dried red pine determined with resistance moisture meter was significantly higher than that of conventional kiln dried wood. But EMCs of other species did not show significant difference between drying methods. EMCs of conventional and high-temperature dried wood determined with electronic moisture meters, especially in the case of the capacitive-admittance moisture meter measurement, were lower than that determined by oven drying method.

There are many problems that occur currently in agriculture industries. The problems such as unexpected of changing weather condition, lack of labor, dry soil were some of the reasons that may cause the growth of the plants. Condition of the weather in local area is inconsistent due to the global warming effect thus affecting the production of the crops. Furthermore, the loss of farm labor to urban manufacturing jobs is also the problem in this industry. Besides, the condition for the plant like air humidity, air temperature, air quality index, and soil moisture are not being recorded automatically which is more reason for the need of implementation system to monitor the data for future research and development of agriculture industry. As of this, we aim to provide a solution by developing IoT-based platform along with the irrigation for increasing crop quality and productivity in agriculture field. We aim to develop a smart garden system environment which the system is able to auto-monitoring the humidity and temperature of surroundings, air quality and soil moisture. The system also has the capability of automating the irrigation process by analyzing the moisture of soil and the climate condition (like raining). Besides, we aim to develop user-friendly system interface to monitor the data collected from the respective sensor. We adopt an open source hardware to implementation and evaluate this research.

The severity of drought could be evaluated by the accumulative rainfall method, soil moisture condition method, storage ratio method, and water supply restriction intensity method, etc. The pattern of drought could be forecast with the most similar pattern of accumulative rainfall out of the file of past rainfall history. The information that how much rainfall should be expected to overcome the present drought could be obtained from the reservoir storage ratio and soil moisture condition.
