Studies on diagnosis and treatment of tumor . abscess . ulcer in intestinal carbuncle were carried out. The result of studies were summerized as follows: 1. By Nai-Gyung carbuncle-tumor arose from disharmony between nutrient and defensive because of cold, abscess arose from fever victory between cold and fever, ulcer arose from decreasing function of Bi-Kam year. By latter literature Bi-Kam year could be interpreted that spleen stomach was invaded evil influence from unattainable vital force of the earth. 2. Sites of intestinal carbuncle were large intestine, small intestine, intestinal inside or outside between large and small intestine, Intestinal carbuncle was common name of a disease about large intestinal carbuncle, small intestinal carbuncle, pelvic intestinal carbuncle, shrink leg intestinal carbuncle etc.. Pain appeared Chunchu-Hyul in large intestinal carbuncle, and Gwanweon-Hyul in small intestinal carbuncle. 3. On abdominal diagnosis tumor had indistinct pain of Gwanweon Chunchu, edema and heary feeling in low abdomen, no excessive pain by hand press and intestinal boiling sound. In abscess pain descended from right side of low abdomen to huckle, and there was rejection against press, feeling about fever,water sound with flank movement. In ulcer hand approach was difficult since excessive pain diffuse to whole abdomen, and perforating ulcer sometimes caused a serious symptom of umbilical pus. 4. On fecal and urinary diagnosis in tumor urine was yellowish red pollakiuria like gonorrhoea and occasional constipation. In abscess uncomfortable rough pain short red early urine like gonorrhoea appeared during urination, and constipation with stinging pain appeared during defecation. In ulcer red rough pyuria appeared, and stinging and pain with puruloid blood appeared during defecation. 5. On treatment in tumor Daiwhang-Tang Daisenggi-Tang Dangui-Jun by dissipation method, calming down method, interior reliance maturation method, in abscess Mokdan-San Euiiin-Tang Jeokduiin-Tang by the method of water repelling pus discharge, acute breaking, in ulcer Takridanggui-Tang Paljin-Tang Bojungikki-Tang were each used by the method of interior reliance, virulence astriction, supplement vital force and blood, supplement spleen stomach. 6. On treatment patient may have to be careful of excessive moving and suprising anxiety. Abuse of acupuncture and moxibustion made patient worse, misuse of analgesics purgative intestinal irrigation etc. could provoke difficult diagnosis and perforation. So you must treat after exact diagnosis. 7. Prognosis of ease tumor ease abscess ease ulcer and ease astriction was good. If the intestinal carbuncle were not to promote to abscess and ulcer for a long time, its prognosis was bad and it could metastasize to cancer because of dark purple with hardness. So tumor abscess ulcer in intestinal carbuncle may be significant of precancerous lesion.

This research was conducted to establish appropriate methods to prune tomato side stems during summer. Cherry tomatoes "Unicorn" (Monsanto Korea, Korea) were grown in the coir based growing medium, and irrigation was controlled time based system. There were three pruning treatments: 1) removing all side stems (ACUT), 2) remaining two leaves on the side stems right below any cluster (PCUT), and 3) remaining two leaves on all side stems (LEFT). Experimental results showed that the occurrence of swollen stems, a symptom of nutrient excess, was influenced by side stem pruning due to blocking of consumption of photosynthetic products. The photosynthetic rate was not different between leaves on main stem and those on side shoots. Therefore the differences in the total amounts of photosynthetic products seemed to come out from the differences in leaf areas on each treatments, influencing on fruit yield difference. The yields and harvesting rates were better in ACUT treatment when tomato plants were harvested until $5^{th}$ cluster, however tomato yield was higher in LEFT treatment when more then $5^{th}$ clusters were harvested.

This study was conducted to suggest proper water management practices after and before broadcasting of rice seed on flooded paddy surface at reclaimed saline soil with two different saline levels in Gyehwado Substation of Honam Agricultural Research Institute (HARI) NICS, RDA for two years from 2004 to 2005. The stable seedling stand in low saline soil of 0.1% salinity was obtained by one time of water exchange after soil rotary Whereas in medium saline soilof 0.3% salinity, three times of water exchange was required for the stable seedling stand. Milled rice yield was not affected by frequency of water exchange in low saline soil, while it decreased sharply in one and two times of water exchange compared with three times of water exchange in medium saline soil. Irrigation water immediately after direct seeding increased the number of seeding stand in low saline soil. With the increase in the interval of water exchange after direct seeding, the milled rice yield decreased. Although the continuous water flowing showed the most number of seedling stand and was increased milled rice yield compared with the others interval of water exchange in medium saline soil, the number of seedling stand and milled rice wasn't significantly different up to exchange of two days interval compared with the continuous water flowing.

Water is critically important for Tricholoma matsutake(Tm) growth because it is the major component of the mushroom by over 90%. The mushroom absorbs water through the below ground hyphal colony. Therefore, the objectives of our study were to investigate spatio-temporal water changes in Tm colonies. This study was carried out at Tm fruiting sites in Sogni Mt National Park, where the below-ground mushroom colonies have been irrigated. To identify spatial water status within the Tm soil colony soil moisture and ergosterol content were measured at six positions including a mushroom fruiting position on the line of the colony radius. To investigate temporal soil moisture changes in the soil colony, Time Domain Reflectometry(TDR) sensors were established at the non-colony and colony front edge, and water data were recorded with CR10X data logger from late August to late October. Before irrigation, whereas it was 12.8% at non-colony, the soil water content within Tm colony was 8.0% at 0-5cm from the colony front edge, 6.2% at 10-15cm and 6.5-7.5% at 20-40cm. And the content was 12.1% at 80cm distance from the colony edge, which is similar to that at the non-colony. In contrast, ergosterol content which is proportional to the live hyphal biomass was only 0.4${\mu}g$/g fresh soil at the uncolonized soil, while 4.9 $\mu\textrm{g}$/g fresh soil at the front edge where the hyphae actively grow, and 3.8 ${\mu}g$/g fresh soil at the fruiting position, l.1${\mu}g$/g at 20cm distance and 0.4${\mu}g$/g in the 40cm rear area. Generally, in the Tm fungal colony the water content changes were reversed to the ergosterol content changes. While the site was watered during August to October, the soil water contents were 13.5∼23.0% within the fungal colony, whereas it was 14.5∼26.0% at the non-colony. That is, soil water content in the colony was lower by 1.0∼3.0% than that in the non-colonized soil. Our results show that Tm colony consumes more soil water than other parts. Especially the front 30cm within the hyphal colony parts is more critical for soil water absorption.

In case of the domestic condition, as the initiating from Sumjin River Dam, total 14 units of multipurpose dams had been constructed in 1965 for the roles of flood control, waterpower generation, irrigation, water supply, industrial water supply. In the case of such multipurpose dam, it produces electric energy by converting the potential energy utilizing its head and quantity of the water into kinetic energy. However, in this process, since during the time when the turbine connected to the hydraulic turbine dynamo revolves and there occurs a loud noise, it brings the physical, mental bad influences to those people also a decline of an effective working efficiency. On such point of view, after selection of various 16 measurement points, this study has measured and analyzed the travelling characteristics of noise generated at the hydraulic turbine dynamo in Daechung Dam, and also has evaluated the degree of indoor noise using the evaluation index such as PSIL, NC. As the result of noise-evaluation, in case of Daechung Dam, since the noise damage grade appears very seriously at various spaces, it is considering that its soundproof measure would be necessitated keenly. Also, it is considered that such data could be utilized as the valuable material hereafter for establishment of an efficient noise-reduction countermeasure and a comfortable working environment for the hydraulic turbine dynamo plant.

This study was carried out to investigate the effect of air humidity and water content of medium on the growth and physiological disorder of paprika in summer hydroponics. Treatments were composed of air humidity of control (over 90%) and dehumidification (low 90%) and water content of 80% and 50%. Time domain reflectometry (TDR) sensors and dehumidifier were used in a drip irrigation system and control system of air humidity, respectively. The early growth of paprika was not affected by air humidity but increased by high water content (80%) of medium. Mean fruit weight was reduced at high air humidity and low water content (50%) of medium, but the fruit number per plant and yield were increased at low air humidity. The incidence of brown fruit stem increased with increasing air humidity and water content of medium. Rate of blossom end rot increased in the low water content medium compared with the high water content medium. The nitrogen (N) was higher content in brown fruit stem than normal stem, but calcium (Ca) was lower.

Environmental and growth factors such as light intensity, vapor pressure deficit, and leaf area index are important variables that can change the transpiration rate of plants. The objective of this study was to compare the transpiration rates estimated by modified Penman-Monteith model and artificial neural network. The transpiration rate of paprika (Capsicum annuum L. cv. Fiesta) was obtained by using the change in substrate weight measured by load cells. Radiation, temperature, relative humidity, and substrate weight were collected every min for 2 months. Since the transpiration rate cannot be accurately estimated with linear equations, a modified Penman-Monteith equation using compensated radiation (Shin et al., 2014) was used. On the other hand, ANN was applied to estimating the transpiration rate. For this purpose, an ANN composed of an input layer using radiation, temperature, relative humidity, leaf area index, and time as input factors and five hidden layers was constructed. The number of perceptons in each hidden layer was 512, which showed the highest accuracy. As a result of validation, $R^2$ values of the modified model and ANN were 0.82 and 0.94, respectively. Therefore, it is concluded that the ANN can estimate the transpiration rate more accurately than the modified model and can be applied to the efficient irrigation strategy in soilless cultures.

Water quality model applicable paddy field was developed using field experiment during 1999 ${\sim}$ 2002. This model involves inputs from fertilization and sediment release as dirac delta function and continuous source function, respectively, and can simulate various processes such as ponded depth, surface drainage, total nitrogen concentration and total phosphorus concentration in a daily basis. The model was calibrated using data collected from field experiments which was irrigated with ground water and validated from field experiments which was irrigated with surface water. The nutrient concentration of surface water depended on the fertilization and dirac delta function can efficiently explain the valiance of nutrient concentration of surface water by fertilizer. As a result of calibration and validation, this model demonstrates good agreement. The model fit efficiencies ($R^2$) of ponded depth, surface concentration of TN and TP were 0.93,0.98 and 0.95, respectively for calibration, and those of TN and TP were 0.99 and 0.70, respectively for validation. We can apply lake and reservoir model to analysis paddy field considered with shallow ponded system, but it will need so many parameters and have much uncertainty. Fortunately, paddy field have a series of cultural practices yearly basis, such as irrigation-fertilization-forced drain-harvest with a similar time , so simple model may explain the mechanism for paddy field. Water quality model for paddy field developed in this study is simply, needs little parameters, but appeared high applicability to evaluate paddy filed drainage. We recommend this model to estimate nutrient loading from paddy field and establish best management practice.

The self-diffusion coefficients of chloride and tritiated water ranged from 4.8 $\times$ 10-7 to 7.2 $\times$ 10-7 cm2/sec and 5.5 $\times$ 10-5 to 1.6 $\times$ 10-4 cm2/sec for three different depths of soil constituents at about 50% water content by volume, respectively Mobility of solute and water was conducted under steady-state flow conditions in a field soil consisting of 70 cm of clay to silty clay over a medium sand. A steady-state water flow conditions was maintained by applying irrigation water at a constant flux of 2cm per day. The water labeled with chloride and tritium was leached into the plot during the steady-state condition for 87 days. The positions of tritium and chloride as a function of soil depth and the time was measured by extracting samples of the soil solution with suction probes. Extremes in solute displacement occurred at equal and different depths within the plot. An analysis of these measurements indicated the observations of the pore-water velocity and the apparent diffusion coefficient were log normally disturbed. Twenty-four soil suction probes, used to identify the rate at which a solute was displaced in the soil, will yield an estimate of the mean pore-water velocity of this soils within a range of approximately 5% of its true value providing the effects of potential solute-soil interaction are taken into account.
