Types of agricultural policy can be catagorized into two general cases: price and income supports. Income supports are any government program designed to provide farmers with higher incomes than they would receive otherwise. These direct cash payments to farmers are known as "deficiency payment" or "direct payment" because they compensate the farmer for the failure of the market to provide farmers with adequate prices. The direct payment to environment-friendly agriculture is a form of income supports for the agriculture production using less pesticides and chemical fertilizers. Because no significant regulation exists on the use of fertilizers substituting chemical fertilizers for crop, the role of the payment on reducing environmental impacts of agriculture is not entirely clear. This uncertainty is likely to be particularly severe in the case that farmers with low-quality land showing greater demand for fertiliser have an incentive to transition to environment-friendly agriculture. The paper shows the case of the current payment system in Korea.

Objective : The purpose of this study was to investigate the effects of the IOPI articulator strength training program on articulator(tongue and lip) muscle strength, numbers of /l, s, ʨ/ articulation accuracy, articulatory numbers, articulation regularity and accuracy in the alternate motion rates, and sequential motion rate changes in patients with spastic dysarthria. Methods : Three cases of patients with spastic dysarthria living in Jeju, Korea, were included in this study. A single subject design was selected to study changes in articulator(tongue and lip) muscle strength, numbers of /ㄹ, ㅅ, ㅈ/ articulation accuracy, articulatory numbers, articulation regularity and accuracy in the alternate motion rates and sequential motion rates. Results : After the articulator strength training program was conducted on patients with spastic dysarthria, there were positive changes in articulator(tongue and lip) muscle strength, numbers of /ㄹ, ㅅ, ㅈ/ articulation accuracy, articulatory numbers, articulation regularity and accuracy on the alternate motion rates and sequential motion rates. Conclusion : Our findings suggest that IOPI articulator strength training program could be very useful for the most representative childeren with cerebral palsy if conducted in various subtypes of dysarthric patients and linked with articulatory function training with IOPI at home.

Objective : This systematic review aimed to investigate the effect of focal muscle vibration in patients with post-stroke spastic hemiplegia. Methods : We searched literature published between April 2009 and October 2017 using PubMed and RISS databases. The main search terms were Vibration therapy, Focal vibration, Somatosensory, Upper limb, and Spasticity after stroke. Based on inclusion/exclusion criteria, 6 articles were selected. Results : Articles on focal muscle vibration intervention ranged from evaluation of application-only vibration to muscle vibration with task-oriented activity. Intervention effects on upper extremity spasticity and function and activities of daily living were assessed. There were significant effects on upper extremity spasticity, function, and cortical excitability. Conclusions : This study can provide information on focal muscle vibration for use by clinical therapists. However, further studies are needed to identify the optimal stimulation site and frequency/amplitude of application to maximize the effects of focal muscle vibration.

This study examined whether there is a difference in cost asymmetry between a corporate listed on KOSDAQ and a corporate listed on KOSPI, and whether there is a difference in cost asymmetry depending on the size of the listed corporate. In the previous study, cost asymmetry was examined only for listed corporate, but the difference in size between KOSDAQ-listed corporate and KOSPI-listed corporate was not examined. However, according to many studies, since the characteristics of corporate and firm risks are different between corporate listed on KOSPI and corporate listed on KOSDAQ, or even for listed corporate, such an impact may affect the decision-making of internal resource allocation. The analysis was conducted that there would be a difference in the impact. For this study, the results of analyzing the KOSPI and KOSDAQ markets from 2011 to 2019 using the cost behavior model of Anderson et al. (2003), There was a difference in cost behavior in the KOSPI and KOSDAQ markets. Overall, as in previous studies, Cost Stickiness was appeared. but in the case of the KOSPI market, Cost Stickiness was mitigated.It was found that corporate with large corporate size made the decision to dispose of idle resources more clearly when sales decreased. In addition, it was observed that the higher the foreign investor's ownership ratio, the KOSPI market, and the larger the corporate size, the more clearly the Stickiness of cost was mitigated. This study expands research on cost asymmetry and reveals that there is a difference between the KOSPI market and the KOSDAQ market, and between the size of the corporate, and has a differentiation from previous studies.

This study was conducted to identify inbreds and hybrids by measuring plant height, root and other characters at early growing stage. Five inbreds and four hybrids were used for the study and results obtained are as follows; 1. Shoot and root length were significantly different between inbreds and hybrids even 5 days after germination. Slight differences within inbreds and hybrids were also observed. 2. Significantly different observations between inbreds and hybrids for stem diameter, fresh weight, and dry matter of root and stem began to show 23 days after germination.

Effect of soil moisture on growth of 2 year old Pan ax ginseng was investigated by pot culture using clay loam and sandy loam soils. In clay loam soil emergence rate of new shoot and stem growth were greatly decreased below 40% of field capacity. In sandy loam soil the growth of stem and leaf were greatly affected below 40% moisture. Root yield showed maximum at 60% moisture and significantly coorelated with stem diameter and root length. Rotten root rate and die back rate of top were least at 60% and gradually increased with either increase or decrease of soil moisture.

The purpose of this study is to analyze how managers' reporting choices affect asymmetric cost behaviors in manufacturing firms in Korea and Japan. In order to analyze the contents, SG&A, COGS, and operating expenses (OE), which were the targets of the previous studies, were analyzed using the operating costs paid in cash (OC) and the operating expenses before depreciation (OEBD) proposed by Shust and Weiss (2014). The differentiation of cost behavior was analyzed. The analysis revealed, first, that both Korea and Japan showed the difference between cost behavior of OE and OC. Specifically, the cost stickiness of OC was higher than that of OE. In particular, it showed that Korea firms have a higher intensity of tangible fixed assets that are weakening the cost stickiness compared to Japanese firms. Second, the occurrence of depreciation costs weakens the cost stickiness in both countries. Lastly, the higher the debt ratio, the more aggressively the cost reduction of Japanese companies. We hope that this study will help to improve the relationship between the two countries at the academic level when the Korea-Japan relationship cools down.

Fourty lines of F4 progenies of an Adzuki bean cross, Jukdoo (Korean local variety) X Nesumimochi (Japanese variety) were used as the material, and these lines were grown in replicated trials in 1967. Phenotypic, genotypic and environmental covariances among all possible traits of eight character are calculated as shown in table 1. Phenotypic, genotypic and environmental correlations among all possible paris of eight characters were calculated as shown in table 2. In general, genotypic correlations were higher than the corresponding phenotypic corresponding phenotypic correlations. The genotypic correlations between seed yield (grain weight per plot) and oter agronomic characters indicated that seed yield was genetically associated with the character of pod number per plant, and grain number per plant, which is closely correlated with pod number pr plant, are affected more in Adzukl bean yield than the other agronomic characteracters.

The purpose of this paper IS to examine the differences of cognition between self-management and corporation in report and payment of Value Added Tax. And then We want to suggest the policy of improvements to reduce the resistance of tax-payer in V.A.T. Data was collected for 250 firms' samples from the self-employed and corporation in Daegu Seongseo Industry District. The main results of empirical study are as follows. First, Value Added Tax is not fair in all companies. But It couldn't find the differences between self-employed a d corporation in statistical meaning. Second, It was found the cooperatives generally think to pay the taxes in rule, but self-employed not do it in the report and payment of Value Added Tax. But we couldn't find the important differences between self-employed and corporation in statistical meaning. We propose to improve the polices of introduction of tax rates of multiples in the charging and to redesign the definition of a tax-payer of value added tax to reduce the resistance in report and payment.
