A study was conducted to obtain acid tolerant and superior Rhizobium meliloti strain for alfalfa on hilly acid soils. With host plant, eight isolates of R, meliloti selected in the vicinity of Milyang were evaluated for their ability to establish symbiotic effectiveness in acidified tube culture medium and vermiculite pot with different urea levels. Among isolates "YA03" was characterized for the ability to manifest to acid tolerance in three different soils of which pH were 5.0, 6.0, and 7.5. The results obtained were summarized as follows: 1. Of eight isolates "YA03" and "YA09" performed nodule in the tube medium of pH5.0, and in the symbiotic effectiveness YA03 was superior to others. 2. Alfalfa growth and $N_2-fixing$ activity by the inoculation of "YA03" isolate were better than others at the level of urea 1.25mM as well as nonurea. 3. Application of urea with inoculation of "YA03" islate to alfalfa was one of the effective factors for symbiotic effectiveness. 4. In infertile soil of pH5.0 inoculation of R. meliloti "YA03" to alfalfa caused the increase of shoot dry matter of 320% as compared to the control, and the total amount of yield was 131% as much yield in moderate fertile soil of pH7.5. Finally R. meliloti "YA03" isolate was selected as an acid tolerant strain.

The purpose of this study is the evaluation of the degree of post injection soreness, symptom duration, factor and autonomic symptoms after trigger point injection in patients with trigger points. We devided the subjects of the study into four groups Such as, only dry needling, needle-TENS, with massage-stretch, massage-stretch only, including 100 patients, and measured the visual analog scale before treatment and after treatment. Before treatment, The VAS mean scores were $6.2{\pm}1.03$ in needle-TENS with massage-stretch group ; $6.2{\pm}1.75$ in needdle-TENS group, and $6.3{\pm}1.85$ in dry needling group, and $6.8{\pm}1.03$ in massage-stretch group. In post injection 3rd day, The VAS mean score were $0.9{\pm}1.78$ in needling-TENS with massage-stretch group, $1.1{\pm}1.52$ in needling-TENS group, $1.7{\pm}1.10$ in dry needling group, and $3.9{\pm}3.01$ in massage-stretch group. As for a causative factor of activities for trigger were overload with 37.0%, overwork with 35.0% and fatigue with 13.0%. Symptoms for trigger were tenderness with 28.0%, numbness and tingling with 24.0%. ROM limit with 17.0% and tightness with 17.0%. As a result, needling-TENS with massage-stretch group showed less soreness and effect than other group.

The effect of CuO and CdO addition on the microwave dielectric properties of $BiNbO_4$, ceramics were investigated. As the content of CdO increased, sintered density and quality factor decreased. With increasing sintering temperature, both the dielectric constant and quality factor increased. In the case of specimen sintered at $960^{\circ}C$ with addition of 0.03 wt% of CuO and CdO, respectively. the microwave dielectric properties obtained were dielectric constant of 41.2, quality factor ($Q{\times}f_0$) of 6,500 (at 5.6GHz), temperature coefficient of resonant frequency of $3ppm^{\circ}C$.

The effect of Milliwrap and Uniwrap attached to the lid on the growth and acclimation of lily growing in vitro was investigated. Milliwrap treatment increased the plant height 1.6 and 1.2 times higher than control in 'Dame Blanche' and '94-36', respectively, plant height of 'Dame Blanche' was 6.1㎝ and '94-36' line was 13.4 ㎝. Two treatments slightly inhibited the fresh weight in 'Dame Blanche', whereas Milliwrap and Uniwrap enhenced the fresh weight more than 30% in '94-36'. Leaf width (1.0 ㎝) of Milliwrap treatment was most wide, which was 2.5 times higher than that of control. In the fresh weight of bulblets, the fresh weight per bulblet of treatment was higher than control in '94-36', but the number of bulblets per scale were few in the treatment to control. In the air composition of culture vessel, ethylene content (0.03 ppm) was low in the Milliwrap treatment compared with the control. CO₂ content of control was higher than treatments as 0.11% and it was about 3 times to air condition of out side. The acclimation ratio of Milliwrap treatment was higher as 85.1% and control was similar with Uniwrap treatment.

Budgets of fresh water, salt, DIP and DIN in the Youngsan river estuary were estimated seasonally in order to clarify the characteristics of material cycling and flux of nutrients with a simple box model. Inflow volumes of freshwater into system was approximately $36.481{\times}10^6{\sim}663.634{\times}10^6m^3/month$ and existing water mass of freshwater in system calculated by salt budget was approximately $2.515{\times}10^6{\sim}5.812{\times}10^6m^3$. Mean residence time of freshwater was calculated to be about 0.26~2.03 day. water exchange $1,248{\times}10^6{\sim}9,489{\times}10^6m^3/month$ assumed with salinity between estuary and adjacent ocean. Inflow mass of DIN and DIN were approximately 76.63~1,149.91 ton/month and 2.91~61.22 ton/month, respectively. Residence times of DIP and DIN were calculated to be 0.45~1.10 day and 0.28~1.92 day, respectively. The ratio of water residence time versus DIP, DIN residence time was calculated that freshwater residence time was longer than DIP, DIN residence time except for summer season. Thus, We assume that circulation of Nutrients in the system will happen rapidly except for summer season. Specially DIP in Winter could assume to outer input source existence because of seawater inflow in system and high DIP concentration in open sea.

The gibberellins (GAs) play important roles in plant growth and development. Twenty three fungi were isolated from the roots of Lindera obtusiloba and Vaccinium koreanum. The numbers of GA-producing fungi were six strains from Lindera obtusiloba and four strains from Vaccinium koreanum. The fungi with GAs-producing activity were incubated for seven days in 40 ml of Czapek's liquid medium at $25^{\circ}C$, 120 rpm, and the amount of each GA in the medium was measured by gas chromatography-mass spectrometer (GC-MS) to determine the productivity of GAs. Penicillium griseofulvum KNU5379 produced more GA in case of $GA_{3}$ than Neurospora crassa known as a GAs-producing fungus. P. griseofulvum KNU5379 was shown to produce $GA_1\;9.79\;ng,\;GA_3\;133.58\;ng,\;GA_4\;2.64\;ng,\;GA_7\;7.80\;ng\;and\;GA_{53}\;0.73\;ng$ in 25 ml of liquid medium. Bioassay using culture fluid of GAs-production fungi was performed on rice sprout.
