A sine with dwell test is well known as a test scenario for evaluation of performance of electronic stability control(ESC) on passenger vehicles and heavy commercial vehicles. However, when it comes to ESC for medium commercial vehicles, the test scenario has not been established yet. In this paper, the sine with dwell test was modified considering characteristics of medium commercial vehicles. The three main modifications of the original test scenario are the steering angle level, steering frequency, and loading condition of the vehicle. These modifications are derived from simulation study for different medium commercial vehicles. From simulation study, it was shown that the ESC system for medium commercial vehicle is objectively evaluated by the proposed test scenario. A clear improvement on vehicle stability was seen in the results when ESC system was used.

In this paper, we assessed the growth of rice seedlings(Chucheong variety) in commercial organic growth medium that was substituted with different ratios of vermicast of oyster mushroom waste grown under potting alone, and potting and floor layering treatment. The commercial organic growth medium was substituted with vermicast at ratios of control, 2%, 4% and 6%, respectively. The control consisted of commercial organic growth medium alone without vermicast. Incorporation of $4%{\sim}6%$ vermicast of oyster mushroom waste into a commercial organic growth medium enhanced the growth of rice seedlings significantly as compared to commercial organic growth medium alone(control), and 2% amended with vermicast in potting treatment. This results demonstrate that substitution with low ratios of vermicast($4%{\sim}6%$) will promote growth of rice seedlings. The growth of rice seedlings in commercial organic growth medium alone without vermicast was enhanced significantly as compared to the substituted with vermicast in floor layering treatment, it may due to nutrient uptake by elongated root from the vermicast when applied to on the floor layering. Floor layering treatment is an effective method for potting processing of vermicast. The vermicast of oyster mushroom waste should have a high safety and great potential as materials of growth media for increasing plant growth, either as soil conditioner, or as substitution or amendments to commercial organic growth medium. For the enhanced growth of rice seedlings, demand to increase with total nitrogen, and decrease with the carbon and nitrogen ratio(C/N) of commercial organic growth medium supplied by such as vermicast.

Domestic automobile companies have adopted drum type brake system for commercial vehicles. However recently those companies have been applying disc-brake system to solve vehicle control-instability and inefficient heat discharge performance of conventional drum brake system for a medium commercial vehicle. Because the kinetic energy of a running commercial vehicle is relatively high, the brake system should discharge lots of heat energy while braking. A ventilated type brake disc has been used to increase heat discharge performance of a brake system. The vent structure of a disc highly affects cooling efficiency. This paper compares thermal characteristics of three types of vent structure in JASO C421 braking condition. It is found that the slant bend type disc has the lowest temperature and thermal stress distributions in the braking condition.

To remove excess nitrate from the agricultural environments, Enterobacter amnigenus GG0461 has been isolated as a bacterial strain having high capability of nitrate uptake activity. This strain was able to remove nitrate more than 3,000 ppm (50 mM) in the Pseudomonas agar F (PAF) medium. Therefore, it could be a candidate strain for a nitrate scavenger in the various contaminated environments, such as agricultural soils, livestock sewage, and industrial wastewater. In order to develop medium for the large-scale production of the strain GG0461, each component of PAF medium was replaced with the corresponding commercial product and the optimal conditions for bacterial growth and nitrate uptake activity were measured. Glycerol was replaced with the commercially available product and the nitrogen source was substituted with commercial tryptone, yeast extract, soybean meal, and fermented fish extract. Bacterial growth and nitrate uptake activity were maximal in the media containing 2% tryptone, followed by yeast extract, soybean meal, and fermented fish extract. The pH of the growth medium containing 2% tryptone was decreased by the bacterial nitrate uptake, suggesting that the nitrate uptake is mediated by a nitrate/proton antiporter. This result shows that the medium containing commercial tryptone was good enough for the physiological activity of the strain GG0461. Each component of PAF medium was successfully replaced with the corresponding commercial product except peptone. In conclusion, the composition of medium for the cultivation of the strain GG0461 was determined as 2% tryptone, 1% glycerol, plus required salts according to the composition of PAF medium.

This research improved the growth potential of Bifidobacterium animalis subsp lactis strain JNU306, a commercial medium that is appropriate for large-scale production, in yeast extract, soy peptone, glucose, L-cysteine, and ferrous sulfate. Response surface methodology (RSM) was used to optimize the components of this medium, using a central composite design and subsequent analyses. A second-order polynomial regression model, which was fitted to the data at first, significantly lacked fitness. Thus, through further analyses, the model with linear and quadratic terms plus two-way, three-way, and four-way interactions was selected as the final model. Through this model, the optimized medium composition was found as 2.8791% yeast extract, 2.8030% peptone soy, 0.6196% glucose, 0.2823% L-cysteine, and 0.0055% ferrous sulfate, w/v. This optimized medium ensured that the maximum biomass was no lower than the biomass from the commonly used blood-liver (BL) medium. The application of RSM improved the biomass production of this strain in a more cost-effective way by creating an optimum medium. This result shows that B. animalis subsp lactis JNU306 may be used as a commercial starter culture in manufacturing probiotics, including dairy products.

A depth filter medium was newly designed in order to achieve high collection of dust and low pressure drop in this work. Multilayer depth filter media consist of an upstream layer of highly porous structure which allows particles to pass through and to follow by one or more downstream layers to hold the particles inside the media. For each filter media, flat sheet and pleated module were made of newly developed depth filter media and filter media of commercial products. Commercial depth filter cartridge for gas turbine air intake cleaning were used as reference for filtration area and pleat geometry of pleated modules. This work attempts to evaluate and compare the newly developed depth filter medium and two commercial filter media in terms of filtration parameters such as air permeability, initial pressure drop, particle retention and pressure drop variation with dust loading. According to the close examination the newly developed depth filter showed better performance compared to the commercial depth filter media.

This paper investigates, in a single equation framework, the effect of bank-specific and macroeconomic determinants on micro-, small- and medium-sized loans by commercial banks in Indonesia. This study uses a sample of 790 observations from 79 commercial banks in Indonesia over the years 2006-2015. This study uses two estimation methods for our panel regressions: static and dynamic generalized method of moments (GMM) panel estimator. In static relationships, the literature usually uses the least square methods on fixed effects (FE) or random effects (RE). I found evidence that all banks, bank profitability and size are positively and significantly related to micro-, small- and medium-sized loans, while the coefficients of liquidity are significantly positive in all specifications, except government banks which is significantly negative. The relationship between risk and credit growth is negative for non-government banks. All estimated equations show that the effect of the capital variable on lending banks to MSMEs is not important in government banks and non-government banks. Finally, macroeconomic variables, such as inflation and gross domestic product, clearly affect the lending of the banking sector particularly non-state banks. The findings have several policy implications to Indonesia government, regulatory authority and bank managers in order to improve bank profitability through bank lending.

This study was conducted to investigate the effect of supporting material and ionic strength of the MS medium on growth of strawberry plantlets cultured in vitro for the rapid mass production. Explants of $Fragaria$ $ananassa$ 'Houkouwase' in vitro were planted in the agar or Tosilee (commercial plug medium) medium as the supporting material and supplied with 1/4 MS, 1/2 MS or basal (as the control) MS medium in an autotrophic micropropagation. Plant height and root length were significantly greater when they were cultured in 1/2 MS medium as compared to those grown in the agar medium. Also, shoot fresh and dry weights, and leaf area in the 1/2 MS medium were greater than in 1/4 MS or basal MS medium. When plantlets were cultured in Tosilee medium and fed with the basal MS medium, plant height, root length, shoot fresh and dry weights, root fresh and dry weights, and leaf area were promoted and greater than those in plantlets cultured in the agar medium.

Commercial transactions, one of the pillars of the capitalist economy, are occurring countless times every day, especially small and medium-sized businesses. However, small and medium-sized enterprises are bound to be the legal underdogs in contracts for commercial transactions and do not receive legal support for contracts for fair and legitimate commercial transactions. When subcontracting contracts are concluded among small and medium-sized enterprises, 58.2% of them do not apply standard contracts and sign contracts that have not undergone legal review. In order to support small and medium-sized enterprises' fair and legitimate contracts, small and medium-sized enterprises can be protected from legal threats if they can reduce the risk of signing contracts by analyzing various risks in the contract and analyzing and informing them of toxic clauses and omitted contracts in advance. We propose a risk prediction model for the machine reading-based legal contract to minimize legal damage to small and medium-sized business owners in the legal blind spots. We have established our own set of legal questions and answers based on the legal data disclosed for the purpose of building a model specialized in legal contracts. Quantitative verification was carried out through indicators such as EM and F1 Score by applying pine tuning and hostile learning to pre-learned machine reading models. The highest F1 score was 87.93, with an EM value of 72.41.

This study was conducted in a commercial plug glasshouse in Sacheon to examine the possibility of producing tomato plug seedlings using various growing media containing cellular glass foam (CGF)and carbonized chestnut woodchips (CCW) as medium components. Plug seedlings of 'Seogun' tomato were grown in media containing 50% CCW＋50% peatmoss, 33% CGF＋67% peatmoss, and 50% peatmoss＋50% granular rockwool. A commercial plug medium (Tosilee) was used as the control. All seeds were sown in 200 cell plug trays on November 28, 2001. Seedling growth was measured at 31 days after sowing. Each treatment showed a similar growth result as compared to the control. Plant height, root grade, fresh weight, and air space and bulk density of the medium were significantly greater in the 33% CGF＋67% peatmoss treatment than those in the other media. However, growth was slightly suppressed in the 50% CCW＋50% peatmoss. pH and EC of the media were the highest in the control treatment, although no toxicity symptoms had been observed. The results suggest that perlite can be replaced with a new material such as CGF in the commercial scale production of plug seedlings of 'Seogun' tomato.
