Brownian-dynamics simulation on highly charged colloidal suspensions is performed by employing Tokuyama effective force recently proposed. The radial distribution function suggests that there exist three novel phases, a gas phase, a liquid droplet phase, and a face-centered cubic (FCC) crystal droplet phase, depending on the minimum values of that potential. The dynamics of droplet growth is also investigated both in liquid droplet phase and in crystal droplet phase. Thus, different types of characteristic growth stages are found.

Objectives : The purpose of this study is to have better data and to make efficient clinical reviews on pre-school children's growth based on two measurements; Body composition for measuring body volume and bone age for potential growth. Methods : The study was conducted with 221 children(118 of boys and 103 of girls) from three kindergartens. Body compositions(soft lean mass, body fat mass, percent body fat) were measured by bioelectrical impedance analysis, bone age was measured by bone density through ultrasonic image of calcaneus. Results and Conclusions : 1. The higher level on weight or BMI, the more averages of soft lean mass, body fat mass, percent body fat. 2. The average bone ages and bone age-chronological age were lower in under 50 percentile's group, but it was higher in upper 50 percentile's group. Also, children with high BMI had older in bone ages and bone age-chronological age. 3. The higher in height percentile based on the bone age; there were more soft lean mass. 4. The averages of bone age and bone age-chronological age were significantly decreased, the more percentiles of height according to bone age were big, they were higher than total average in under 50 percentile's group of height, lower than total average in over 50 percentile's group of height in both boys and girls. 5. The average of MPH were significantly decreased in top percentiles of children's height distribution. Also, in the upper percentiles of height distribution based on bone age were big in only boys. 6. The body compositions(soft lean mass, body fat mass, percent body fat) were related to body volume growth, which can he measured by weight or BMI. The bone age, bone age-chronological age, and MPH were related in terms of hight. The body volume growth was a little hit related with potential growth.

A phosphate-solubilizing bacterial strain isolated from Hippophae rhamnoides rhizosphere was identified as Rahnella sp. based on its phenotypic features and 16S rRNA gene sequence. The bacterial strain showed the growth characteristics of a cold-adapted psychrotroph, with the multiple plant growth-promoting traits of inorganic and organic phosphate solubilization, 1-aminocyclopropane-1-carboxylate-deaminase activity, ammonia generation, and siderophore production. The strain also produced indole-3-acetic acid, indole-3-acetaldehyde, indole-3-acetamide, indole-3-acetonitrile, indole-3-lactic acid, and indole-3-pyruvic acid in tryptophan-supplemented nutrient broth. Gluconic, citric and isocitric acids were the major organic acids detected during tricalcium phosphate solubilization. A rifampicin-resistant mutant of the strain exhibited high rhizosphere competence without disturbance to the resident microbial populations in pea rhizosphere. Seed bacterization with a charcoal-based inoculum significantly increased growth in barley, chickpea, pea, and maize under the controlled environment. Microplot testing of the inoculum at two different locations in pea also showed significant increase in growth and yield. The attributes of cold-tolerance, high rhizosphere competence, and broad-spectrum plant growth-promoting activity exhibited the potential of Rahnella sp. BIHB 783 for increasing agriculture productivity.

본 연구는 한우송아지 모축의 포육능력별 육성률과 밀접한 관계가 있는 혈중 성장면역관련물질, 증체 및 질병 발병율을 조사하기 위해 수행되었다. 시험축은 축산연구소에서 다형성 발굴을 위해 보유중인 계통조성축으로부터 생산된 한우 송아지 40두를 공시하여 모축의 포육능력에 따라 고능력과 저능력구에 각각 20두씩 배치하여 두 개의 처리구를 두었다. 송아지 혈중 IGF-I, RBC, Ca 및 IP 농도는 생후 5일령에서 RBC 농도가 고능력 처리구에서 높게 조사된 것을 제외하고는, 전 시험기간 동안 이들 물질의 농도는 송아지 모축의 포육능력에 상관없이 두 처리구간 유사하였다. 한편, 송아지 혈중 IgG, albumin, total protein 및 GGT 농도는 모축의 포육능력에 상관없이 두 시험구간 유사하였으며, 반면에 이들 물질 중 total protein이 조사 기간 동안 일정 농도를 유지한 것을 제외하고는, IgG, albumin 및 GGT 농도는 송아지 생시 및 생후 일령에 의한 영향을 받았다. 송아지 체중은 모축 포육능력에 의한 직접적인 영향은 없었지만, 고능력 시험구에서 이유후 6개월령까지 체중이 증가하는 경향을 보였으며, 호흡기 질병과 설사 발병율은 고능력 시험구에서 감소되는 경향을 보였다. 따라서 한우의 포육능력은 포유기 및 이유 후 송아지의 성장과 면역에 부분적 영향을 미치며, 질병에 대한 면역력 증진에 영향을 미치는 것으로 사료된다.

마늘 흑색 썩음균핵병인Sclerotium cepivorum에 대한 수분압과 온도의 영향을 얄아보기 위하여 PDA와 PDB에 NaCI, KCI, 설탕 및 polyethylene glyool 6,000으로 수분압을 조절한 수 15, 20, $25^{\circ}C$에서 균사생장 및 균핵 생성량을 조사하였다. 균사신장은 -1,970에서 -2,240 J/Kg까지는 크게 영향을 받지는 않았으나, =2,240 J/Kg 이하에서는 균사신장이 급격히 저하되었다. -450에서 -2,240 J/Kg까지의 수분압에서는 기본배지에서보다 건물중이 약간 증가하였다. 수분압 감소에 따른 건물중에의 영향은 균사신장에서 보다는 작았다. PEG를 이용해 수분압 조절했을 경우 균사신장과 건물중 모두 다른 용질을 사용했을 경우보다 크게 감소했다. 균사신장은 -1,000 J/Kg에서, 건물중은 -2,240 J/Kg에서 약 50%가 각각 감소했다. 수분압 감소에 따른 균핵 형성에 대한 영향은 균사생장에서 보다 더욱 컸다. -450에서 -910 J/Kg 사이에서 균핵형성이 50% 이상 줄었으며, -2,240 J/Kg 이하에서는 균핵이 형성되지 못했다. 균사신장과 균핵형성은 기본배지에서는 $20^{\circ}C$dptj 양호하였으나, 수분압이 감소하면서 $25^{\circ}C$에서 더 좋은 경향을ㄹ 보였다. NaCl, KCI 설탕 및 PEG에 따라 차이는 있었으나, 균시생장과 균핵 형성은 비슷한 경향의 증감을 보였다.

Fatigue crack growth rates(i.e. crack initiation and crack growth of short and long crack) are investigated using commercial plates of high strength Al alloy 7075-T651 for the transverse-longitudinal(T-L) direction in air, water and sea water. Also, the evaluation direct current potential drop(D.C.P.D) method and the fractographical analysis by SEM are carried out. Near threshold region, short crack growth rates were much faster than those of comparable long cracks, and these short crack growth rates actually decrease with increasing crack growth and eventually merge with long crack data. Fatigue crack propagation rates in aggressive media(i.e. sea water) increase noticeably over three times those in air. One of the most significant characters in this phenomenon as a corrosion-fatigue causes an acceleration in crack growth rates. Sea water environment, particularly Cl$^{[-10]}$ solution brings the most detrimental effects to aluminum alloy. The result of fractographical morphology in air, water and sea water by SEM shows obvious dimpled rupture and typical striation in air, but transgranular fracture surface in water and sea water.

Since the advent of growth hormone(GH), children with a wide variety of growth disorders have received GH treatment. In GH deficiency(GHD), Turner syndrome, chronic renal failure, children born small for gestational age, Prader-Willi syndrome, and idiopathic short stature, the therapeutic effects and safety profile of GH are reviewed. GH therapy has been clearly shown to improve height velocity and final adult height in a variety of pediatric conditions in which growth is compromised irrespective of GHD. Early initiation and individualization of GH treatment has the potential to normalize childhood growth. The supra-physiological doses of GH have been shown to increase height velocity during childhood and final height in non-GHD conditions. Adverse events during GH therapy are uncommon and often not drug related. However continued surveillance into adult life is crucial, especially in children receiving supra-physiological doses or whose underlying condition increases their risk of adverse effects.
