The wasabi was planted in glasshouse to investigate the effect shade level (0, 10, 30, 70%) on growth and photosynthetic response. The net photosynthetic rate and stomatal conductance were the highest under 10% shading rate in greenhouse. The lowest transpiration rate was in the non-shading treatment. 70% shading rate significantly reduced in photosynthetic characteristics. The number of leaf was decreased with increasing of shading rate. Leaf and petiole weight was the highest 10% shading and then followed by the non-shading treatment. Number of leaves, leaf, petiole and total weight were severely declined in 70% shading treatment. Shading rate (0%, 10%, and 30%) did not significantly influenced on the leaf length, leaf width and root growth. 10% shading level was the most effective for wasabi leaf production in hydroponics.

This study was conducted to obtain practical information on the efficient drying of animal manure under the sunny dry condition. The effects of the height of manure pile (5, 10, 15, and 20cm), stirring times (0, 1, 2, and 4 times/day), the addition of dried manure (30%, w/w), and the type of drying bed on the removal of water from fresh pig manure were investigated in a plastic house. Pig manure was dried very well by lowering the height of manure pile and the drying efficiency was the highest at 10cm height. Water evaporation rate was the greatest at the twice stirring per day treatment. The addition of dried manure as bulking material enhanced the water evaporation rate of wet pig manure. The amounts of water removed for 19 days under the condition of 10cm height of manure pile and twice-stirring in spring, summer, autumn and winter were 75.6, 73.3, 54.6 and $32.6kg/1.2m^2$, respectively.

To provide the basic data essential for developing varieties of broad-leaved tree, the study investigated the utmost growth requirement for the growth characteristic and biomass production in accordance with planting density of Styrax obassia. The planting density of seedling can be a significant factor in contributing growth of seedling for tree growing in general. While growth of tree according to $1m^2$ planting density of Styrax obassia showed an excellent growth in tree height and the root collar diameter from $49no./m^2$, those low planting density showed decreased tendency with tree height growth while increasing the root collar diameter growth. As similar to the growth characteristic, the biomass production showed significant and statistic difference in $49no./m^2$, showing high volume of biomass production which is $3.12{\pm}0.80g$ compare to other processing section and high figure with T/R ratio which is 1.59. The special trait of photosynthetic also showed relatively high photosynthetic rate in $49no./m^2\;and\;64no./m^2$ of Styrax obassia and as the density increase, photosynthetic efficiency decreased. The plant showed stable and physiological planting pattern, displaying the best photosynthetic rate, which was the final metabolism through reserving proper space in the growth and development environment condition. This obstacle of required space essential for growth substantially deteriorated planting and ultimately, it demonstrated lower tendency of photosynthetic rate, which is the highest level of metabolism.

Purpose: Although several chemotherapy regimens used against advanced gastric cancer (AGC) have been studied extensively in an attempt to further improve the prognosis of patients, to date, no standard chemo-therapeutic regimens have been established. The aim of this study was to determine the anti-tumor efficacy and safety of TS-1 or TS-1 plus cisplatin (CDDP). Material and Methods: We treated 78 patients with AGC either with $80\;mg/m^{2}$ of TS-1 for 28 days, which was followed by a 2-week rest, or with $80\;mg/m^{2}$ of TS-1 for 21 days and $80\;mg/m^{2}$ of CDDP on day 8 every 5 weeks. Results: Tumor response rates in the neoadjuvant chemotherapy group and in the recurrent or post-palliative surgery group were 87.5% and 32.4%, respectively, and they were 28.6% and 48.4%, respectively, in the TS-1 group and the TS-1 plus CDDP group. The survival rates in the recurrent and the post-palliative surgery group were significantly different according to the degree of tumor response (P=0.0016), but the one-year survival rates according to the kinds of regimens (TS-1 or TS-1/CDDP group) were not significantly different. The incidences of grade 3 or 4 adverse effects in the TS-1 and the TS-1/CDDP groups were 14.3% and 36.8%, respectively. Conclusion: The anti-tumor efficacy and safety of TS-1 and TS-1 plus CDDP in Korean patients with AGC seemed to be high with modest adverse effects, thus suggesting the possible use of this regimen as a standard chemotherapy for gastric cancer.

Oriental melon and watermelon plants were cultivated in the soil treated with bioceramics in a greenhouse during summer season from June 1st to August 20th, 1995. Two application methods were employed, one was a mixed treatment of soil and bioceramics, and the other was a spray treatment of bioceramic solution on the stems and leaves. And two types of bioceramics were also stopped by five levels. In order to analyze the bioceramic effect on oriental melon and watermelon, the growth rate of stems, leaves and fruits were measured in the greenhouse. After harvest, the sweetness of fruits was measured and the freshness of fruits based on the storage period was tested by human taste and smell sense. The results are summarized as follows. 1. The growth rates of stems, leaves and fruits of oriental melon and watermelon were the largest in the bioceramic treatment of No. 3. 2. The density of oriental melon and watermelon was the largest in the bioceramic treatment of No. 3 and No. 2 respectively. 3. The Brix number of watermelon was 10.6 in non-bioceramic treatment and 11.5 in the bioceramic treatment of No. 2, and that of oriental melon was 8.6 in non-bioceramic treatment and 12.3 in the bioceramic treatment of No. 2. 4. The storage duration of watermelon treated with bioceramics was about 50 days in the condition of the ambient temperature of 25-3$0^{\circ}C$.

Biological and chemical characteristics and trophodynamics in the frontal zone were investigated in the southern waters of Korea, Temperature, nutrients (dissolved inorganic nitrogen, $PO_4^{3-}-P$, and $SiO_2^{-}-Si$) chlorophyll a and zooplankton were collected and analyzed along the two transects, the frontal zone and the non-frontal zone, in April, 1994. Nutrients were higher in the non-frontal zone than in the frontal zone. But chlorophyll a concentration was high in the frontal zone, particularly at the 20 m depth of the main frontal station (St. TII-2), where was located at the junction between the stratified layer and the non-stratified layer with the lowest nutrients. Zooplankton was more abundant in the frontal zone than in the non-frontal zone, particularly at the innermost station of the frontal zone. Copepods showed high composition rate more than $90\%$ at all stations except the main frontal station (St. TII-2). At the main frontal station (St. TII-2), euphausiids and siphonophores were dominated. Chlorophyll a revealed a significant relationships with $SiO_2^{-}-Si$ in both transects and copepods in the non-frontal zone. Copepods also showed very close relationship with siphonophores in the frontal zone. This suggests that the abundance of copepods could be controlled as bottom-up in the non-frontal zone and as top-down in the frontal zone.

In order to increase network lifetime, duty-cycle MAC protocols which can reduce energy consumption caused by idle listening is proposed for WSNs. In common duty-cycle MAC protocols, each sensor node calculates its duty-cycle interval based on the current amount of residual energy. However, in WSNs with the capability of energy harvesting, existing duty-cycle intervals based on the residual energy may cause the sensor nodes which have high energy harvesting rate to suffer unnecessary sleep latency. Therefore, a duty-cycle scheduling scheme which adjust the duty-cycle interval based on both of the residual energy and the energy harvesting rate was proposed in our previous work. However, since this duty-cycle MAC protocol overlooked the performance variation according to the change of duty-cycle interval and adjusted the duty-cycle interval only linearly, the optimal duty-cycle interval could not be obtained to meet application requirements. In this paper, we propose three methods which calculate the duty-cycle interval and analyse their results. Through simulation study, we verify that network lifetime, end-to-end delay and packet delivery ratio can be improved up to 23%, 44% and 31% as compared to the existing linear duty-cycle scheduling method, respectively.

This Experiment was conducted to determine the effects of light shield materials when melon grown inside a plastic greenhouse in summer season. The average temperatures were 36.6℃, 34.5℃ and 34.0℃ respectively for the control(non-shield), coating agent, and the white net. The light transmittances were 69% and 75%, respectively inside the greenhouse treated with the coating agent and white net immediately after applicants, compared with that inside the control greenhouse. At the 40 and 80 days after treatment, the light transmittances for the coating agent were 92% and 98%, respectively, indicating it was slowly decomposed and removed, but there was no change in the transmittance for the white net. While the leaf number did not differ among the treatments, the plant height was higher in the white net and shading agent than in control. The weight of the leaves, fresh-weight and dry-weight were no different from that of shading, but it became heavier in the later stages. The marketable fruit yield was increased by 6% for white nets and 5% for the coating agent compared to control, there was no statistical significance. Therefore, coating agent is considered as an effective method to lower temperature during high temperature period, but it is preferable to use it in consideration of cultivation period, because the coating agent is gradually removed.
