The effects of dietary supplementation with the sodium salt of isobutyric acid in a low protein (10% CP) wheat straw based diet on nutrient utilization, blood metabolites and growth performance were studied with male crossbred calves. The calves were divided into two equal groups of 6 each. The animals of the control group were fed a basal diet consisting of wheat straw, concentrate mixture and green oat fodder in 40:40:20 proportion whereas BCFA supplemented group received the basal diet+isobutyric acid at 0.75 percent of basal diet. The duration of study was 120 days. The feed intake between experimental groups did not differ significantly and the average total DMI (% BW) was 1.99 and $1.95kg\;day^{-1}$ in control and BCFA supplemented diets. The dietary supplementation of BCFA improved (p<0.01) the DM, OM, CP (p<0.05), NDF and cellulose digestibilities by 8.50, 9.01, 5.39, 17.78 and 18.44 per cent over those fed control diet. The total N retention on BCFA supplementation was improved (p<0.01) due to the decreased (p<0.05) faecal N excretion. The BCFA supplementation did not alter the blood circulatory levels of glucose, total protein, albumin, urea N and amino acids. However after 120 days of experimental feeding a significant (p<0.05) increase in the concentrations of non-esterified fatty acid was observed in control group. The DCP intake and the DCP content of experimental diets was similar in both groups. However, the TDN content of BCFA supplemented diet was significantly (p<0.01) higher (64.35%) than that of control (59.60%). The total live weight gain in BCFA supplemented diet increased by 15.94% over control. The average daily gain and efficiency of feed conversion were also improved in BCFA fed calves by 13.38 and 26.71% respectively, compared to control. It is concluded that dietary supplementation with isobutyric acid improved the digestibility of nutrients and growth performance of calves.

식물성장촉진 뿌리박테리아(PGPR)을 사용한 생물학적 조절(Biological control)은 최근 몇년 동안에 주목 받게 되었다. PGPR은 산업적으로 중요한 감자, 토마토 그리고 쌀과 같은 경제적으로 중요한 작물의 성장촉진과 관련되어있다. 음식물 쓰레기에서 발견된 Bacillus mojavensis KJS-3은 Aspergillus terreus, A. fumagatus, A. flavus and Fusarium redolense에 대해 항진균작용을 가지고 있는 균주로, 이미 여러 산업적인 측면에서 유용한 가능성이 확인된 균주이다. 본 연구에서는 Bacillus mojavensis KJS-3를 알타리무와 상추에 $0.5{\times}10^9cfu/g$, $1.0{\times}10^9cfu/g$ 및 $2.0{\times}10^9cfu/g$의 3가지 농도로 분무, 재배한 후, 잎의 수, 길이, 무게, 뿌리와 근경의 길이, 넓이 및 무게를 비교함으로써, 이들에 대한 생육촉진작용을 확인해보았다. 그 결과, 처리하지 않은 군에 비하여 Bacillus mojavensis KJS-3를 처리한 군이 더 높은 생육성장을 보였으며, $1.0{\times}10^92cfu/g$농도에서의 재배는 저농도에서의 재배보다 더 높은 생육 성장을 그리고 고농도에서의 재배와 비슷한 생육성장을 나타내었다. 이러한 결과를 토대로 B. mojavensis KJS-3의 생물학적 비료로서의 가능성을 확인할 수 있었으며, 또한 B. mojavensis KJS-3의 다른 작물에 대한 생육조절제의 적용도 가능할 것으로 예상된다.

Annual bluegrass는 종자 생산능력이 뛰어나고 한번 조성이 되었을 때 그 분얼경과 지상부 생육이 뛰어나, 전 세계에 가장 널리 퍼져 서식하는 잔디 초종중의 하나이다. 또한 낮은 예초에 적응하는 능력과 조성이 되었을 때 균일성이 좋은 것으로 알려져 있다. Annual bluegrass의 지상부가 성장하기 가장 좋은 온도 범위가 $16-21^{\circ}C$이며 지하부 성장을 위한 최적의 온도범위는 $13-18^{\circ}C$로 고온과 저온에 취약한 초종이다. Annual bluegrass를 관리하기 위해서는 질소와 인산의 비교적 높은 시비량은 annual bluegrass의 확산을 촉진하며 반대로 낮은 시비량은 방제에 도움이 된다. 질소원으로 ammonium sulfate를 사용했을때 sulfate에 의해서 낮아진 토양 pH는 토양속에 존재하는 인이 용해되는 것을 감소시키고 annual bluegrass에 피해를 주는 aluminum의 양을 증가시켜 방제에 효과적이다. 관수는 light and frequent 보다는 deep and infrequent 관수방법이 방제에 도움이 되며 예초높이는 낮추고 예지물은 회수 하는 것이 annual bluegrass의 방제에 도움이 된다. 우리나라에서는 화학적 방제가 주를 이루고 있는데 발아전 처리제로서 prodiamine, bensulide, dithiopyr등이 있으며 발아후 처리제로는 ethofumesate, bisbyribac-sodium 그리고 최근에 연구가 되고 있는 mesotrione등이 있다. 발아전 혹은 발아후 처리제 이외에 생장조절제가 annual bluegrass 방제에 이용이 되고 있는데 paclobutrazol, flurprimidol 등이 있다. 우리나라에서 많이 사용이 되고 있는 생장조절제인 trinexapac은 오히려 여름철 annual bluegrass에 좋은 효과를 나타내고 있어 방제에 적합하지 않다. Annual bluegrass의 방제 효과를 극대화 하기 위해서는 관리적 방제와 화학적 방제의 두 가지 방법이 동시에 고려되어야 할 것이다.

저면도포 무처리구에서 유기상토에 느타리버섯 폐배지로 생산한 분립 4-6%의 첨가비율에서 벼의 유식물체의 생육이 가장 좋았다. 저면도포 처리구에서는 대조구(유기상토 100%)에서 벼의 유식물체의 생육이 가장 좋았는데, 이는 신장된 뿌리가 토양표면에 시용된 분립으로부터 생육에 필요한 양분을 흡수하였기 때문으로 추정된다 따라서 장기간 육묘할 경우에는 유기상토에 분립을 혼합하지 않고 토양표면에 분립 100%를 시용하는 저면도포 방법이 효율적이라고 생각된다. 느타리버섯 폐배지로 생산한 분립은 중금속 함량이 낮아서 안전성이 높고. 양분공급능력이 높은 유기상토재로서 이웅 가능성이 높다고 판단된다. 유기상토의 양분공급능력을 높여 유식물체의 생육을 촉진하기 위해서는 분립과 같은 상토재의 첨가를 통하여 질소함량은 높이고, 탄질율은 낮추는 것이 필요하다고 판단된다.

This paper empirically examines how controlling strategic goods affects productivity by focusing on Korean industries from 2015 to 2019. We hypothesize that strategic goods control positively affects productivity because it promotes international trade by making up for market failures, building up national credibility, and stabilizing market environment; in turn, international trade contributes to productivity growth. The regression results are congruent with our hypothesis. The effects of strategic goods control on productivity were positive and statistically significant in general. These positive effects were more prominent in the group of industries that include strategic goods and, thus, are technologically intensive. The results also support that international trade is a key medium for the effects of strategic goods control on productivity. Consequently, our empirical results support government policy on strategic goods control, ensuring that strategic goods control can contribute to economic growth by reducing diplomatic friction and stabilizing the global market.

Purpose: The study was attempted to provide basic materials for development of nursing-intervention programs by examining effects of growth hormone therapy on the quality of life, depression and self-esteem. Method: A survey was conducted for 31 adult outpatients as experimental group who have received growth hormone therapy more than 6 months and for 29 adults as control group who have not. A scale developed by Hilditch was used to measure their quality of life and also, the Zung's Self-rating Depression Scale and the Rosenberg's Self-esteem Scale were adopted to measure their depression and self-esteem each. Data were analyzed using one-way and two-way ANOVA Result: 1) there were differences between the two groups in the overall measurement of the quality of life. the growth hormone therapy group was higher in sub-factors 2) There were clear-cut differences between the two groups in depression, so that the control group marked higher score in the measurement of depression. 3) Self-esteem was not identical across the two groups, so that it was more higher for the growth hormone treatment group. Conclusion: Those findings suggest that development of education programs related to growth hormone and nursing-intervention is promising.

This study was carried out to improve rehabilitation effect by hydro-seeding methods on denuded slopes. Lespedeza cyrtobotrya, Indigofera pseudotinctoria, Arudinella hirta, Poa pratensis, and Lolium perenne were used in this study. The results of the germination and growth characteristics by seed coating, slope control and soil mulching treatments are summarized here. Seed coating of those plants had an effect on germination ratio, germination force, $LD_{50}$, and seedling growth of stem, leaf and root. The seed coating effect was highest for I. pseudotinctoria while the seedling growth was best for L. cyrtobotrya. Vermiculite+Talcum was the best coating material for germination and seedling growth of the plants. As the slopes were steeper, germination ratio was lower and seedling growth of stem and root decreased. Lots of seeds and soils were swept away when the slope was steep. Soil mulching was effective for germination, seedling growth of stem and root, and soil stabilization. It was more effective when the slope was steeper. Coir net was the most effective soil mulching material n this study.

This work examines the effect of treatment with Gyukhachukeotang on the growth of uterine myomal cells. Comparisons of cell growth, MAP kinase activity and expression of bcl-2 (apoptosis-related gene) were made between the control and experimental samples. The results as fallows; 1. Any concentration of Gyukhachukeotang above 0.01% yielded growth inhibition. Concentrations of 5% and 10% stopped all cell growth, demonstrating the effectiveness of Gyukhachukeotang as a growth inhibitor on uterine myomal cells. 2. The MAP kinase activity in uterine myomal cells treated with Gyukhachukeotang was decreased to a high degree at the concentration of 10%, and some inhibition of activity was detected at a concentration of 5%. 3. The expression of bcl-2, a Cell Apoptosis-related gene, in uterine myoma cells treated with Gyukhachukeotang was gradually increased with increasing concentration of Gyukhachukeotang. These results indicate the ability of Gyukhachukeotang to control uterine myomal cell growth, with concurrent reduction of MAP kinase activity. Treatment with Gyukhachukeotang appears to trigger a normal apoptosis response, as indicated by increased bcl-2 expression. This observed increase in apoptosis indicates that Gyukhachukeotang is an appropriate prescription to treat uterine myomal cells.
