Internationalization of SMEs has gathered pace in recent times with falling trade barriers and rising world trade encouraging small firms to seek profits and growth in foreign markets. This has attracted the attention of researchers, and several studies have been conducted in Western nations on the factors influencing the process of SME internationalization. However, hardly any study has been done on SME internationalization in the Gulf Cooperative Council (GCC) region, thus leaving a gap in the literature. This study investigates the influence of four factors, namely, human capital, network competency, entrepreneurial orientation, and market volatility on the degree of internationalization of SMEs in Oman. The study employs survey data collected from 150 SME owners and managers using a structured questionnaire having 27 items, and has been analyzed using correlation and logistic regression, as the dependent variable is binary in nature. The results reveal the impact of the chosen variables on the degree of internationalization of SMEs. The findings of the study suggest that network competency has the highest impact on degree of internationalization of Omani SMEs, followed by human capital and entrepreneurial orientation, while market volatility, though insignificant, moderated the relationship between entrepreneurial orientation and degree of internationalization of Omani SMEs.

The purpose of this study was to examine the effects of a child's demographic variables and maternal perceptions of the conditions of happiness on their happiness for mothers. The participants of this study comprised 916 mothers of young children, school-aged children, and adolescents. The results revealed that a child's age and the numbers of children influenced maternal happiness when mothers' demographic variables were controlled. In addition, mothers who exhibited high degree of need in terms of the conditions of happiness regarding existence, relatedness, and growth were more likely to be happy than mothers who exhibited low degree of needs. Finally, the expectations regarding growth, which refers to the pursuit of self-accomplishment and meaning, was the most important predictor of maternal happiness. These findings have implications for parent education programs for mothers of young children, school-aged children, and adolescents.

The aim of this study was to bring light on the effect of permeability to yield weight of paddy rice on the compressed soil. a) The percolation volume during the growth of paddy rice reduced, while the degree of compression on soil column increased and varied by the evaporation and absorption volumn. b) The percolation volume in the natural soil column was notably low compared with that of in the artificial and had little influence to the variation of permeabilty by compression. c) The results in growth of paddy rice were best on the section of low compression and the yield weight reduced, while the degree of compression on the soil column increased. d) The relationship between the yield weight and percolation volumn, under the condition when percolation volume is 1mm/day, had little difference in the yield weight but immediately reduced under $0.5{\sim}1.0mm/day$. The consequences of investigation are not so perfect, but have done my best to get some new data for effect on additional yield by inquiring into influences of permeability to the yield weight of paddy rice on compressed paddy field. I will have a great pleasure if treatise helps investigaters or the men of affairs in this field.

For high quality bread wheat production in Korea, it is necessary to develop optimal nitrogen (N) fertilizer methods. For optimal N fertilizer, we evaluated the alteration of growth, yield, yield components and end-use qualities according to the treatment of N fertilizer amounts and timings at heading stages. Growth, yield, yield components, and end-use quality weren't altered by various timings of N fertilizer treatment conditions whereas, 1,000 grain weight and lodging degree was increased by increasing amounts of N fertilizer treatment conditions at 7 days after heading (7 DAH). Especially, lodging degree was significantly increased by 6kg/10a of N fertilizer treatment conditions at 7 DAH. The flour protein contents increased by various amounts of N fertilizer treatment conditions. However, SDS-sedimentation and bread loaf volumes were decreased by exceeding 6kg/10a of N fertilizer treatment conditions at 7 DAH. When considering the quality of bread, 6kg/10a N fertilizer treatment is best, but 3kg/10a N fertilizer treatment is more suitable for both quality and lodging at 7 DAH. Therefore, it is preferable to fertilize 3kg/10a of nitrogen at 7 DAH in addition to standard fertilizer when cultivate bread wheat.

A mathematical model has been developed for predicting kinematic, thermal, and solidification histories of atomized droplets during flight. Liquid droplet convective cooling, recalescence, equilibrium-state solidification, and solid-phase cooling were taken into account in the analysis of the solidification process. The spherical shell model was adopted where the heterogeneous nucleation is initiated from the whole surface of a droplet. The growth rate of the solid-liquid interface was determined from the theory of crystal growth kinetics with undercooling caused by the rapid solidification. The solid fraction after recalescence was obtained by using the integral method. The thermal responses of atomized droplets to gas velocity, particle size variation, and degree of undercooling were investigated through the parametric studies. It is possible to evaluate the solid fraction of the droplet according to flight distance and time in terms of a dimensionless parameter derived from the overall energy balance of the system. It is also found that the solid fraction at the end of recalescence is not dependent on the droplet size and nozzle exit velocity but on the degree of subcooling.

The purpose of this study was to examine the tissue response to experimental furcation perforations immediately treated with Super EBA, Ketac Silver, MTA and Emdogain using surgical microscope. Forty experimental furcation perforations were created in the mandibular and maxillary premolars and molars of 4 adult dogs and immediately repaired with experimental materials. The animals were sacrificed after 16 weeks and radiographic and histologic results were evaluated. The results were as follows. 1 All materials tested in this experiment revealed a certain degree of extrusion of the filling materials and infiltration of inflammatory cells into the periodontal space. Except MTA group, epithelial down-growth of the surrounding gingiva was found in all experimental groups. 2. Both Ketac Silver and Emdogain group showed the greatest degree of inflammatory reaction and bone resorption. 3. Super EBA group showed moderate inflammation and newly bone formation under the perforation area. 4. MTA group showed minor inflammation, new bone regeneration toward restorative materials and partially cementum growth onto the surface of the material. This group demonstrated a favorable prognosis.

These studies were conduced to investigate the effects of temperatures on development of each stage and distribution within tree and overwintering of mulberry scale, Pseudaulacaspis pentagona Tar. & Tozz. Growth ratio of each stage with different temperatures was not significant within range of optimum temperatures of growth. Developmental threshold and effective temperatures of each stage were $12.3^{\circ}C$ and 46.9 degree day in eggs, $10.8^{\circ}C$, and 183.8 degree day in first nymph, $9.8^{\circ}C$ and 188.2 degree day in second nymph, $10.3^{\circ}C$ and 383.0 degree day in gross nymphal stage, respectively. Longevity of female adults were 39.6 days in $18^{\circ}C$, 28.4 days in $22^{\circ}C$, 18.1 days in$26^{\circ}C$, and 15.7 days in$30^{\circ}C$. Average number of eggs in ovary and laid by individual female were 83.3 and 75.7, respectively. Optimum temperatures of growth were $22^{\circ}C$-$26^{\circ}C$ but all the eggs were not hatched at $35^{\circ}C$. Distribution of each stage within tree in summer was great at lower part of branch and overwintering adults was dominantly located in NE-SE followed by SE-SW, SW-NW and NW-NE. Percent mortality due to cold weather was 36.2.

This study was conducted to investigate the effect of environment factors on full bloom stage and fruit width in four peach cultivars. The average temperature in March was the main factor to determine the date of full bloom in 'Kurakatawase'($-0.6871^*$) and 'Changhowon Hwangdo'($-0.5270^*$). The fruit growth curve after 35 days from full bloom was the double sigmoid shape in 'Changhowon Hwangdo' cultivar. Environmental factors affecting fruit width were mean diurnal range(BIO2) and temperature annual range(BIO 7) in 'Kurakatawase', growing degree days(GDD) after 30 days from full bloom and July precipitation in 'Yumyeong', and annual mean temperature(BIO1), BIO7, and July precipitation in 'Kawanakajima Hakuto'. Of these, major environmental factors affecting fruit width in more than two cultivars were BIO7 and July precipitation.
