This study was conducted to evaluate the effects of seeding time of ryegrass+hairy vetch on the nutrient contribution and growth of the crops. in order to develop utilization of cover crops as an organic nutrient source in a pear orchard. The study was conducted at a diligent farmer in Boseong in Chonnam, and the both ryegrass and hairy vetch applied on 1) 27 September, 2) 15 October, 3) 8 November, and 4) 10 December of 2008 as a cover crop treatment. Sod culture was refereed as a control. Growth of ryegrass was not affected by seeding time, but hairy vetch had fewer leaf and shoot number as seeding time advanced from September to December, and the similar trend was observed for the dry weight of the crops by seeding time. Seeding of cover crop on September was 2.6 times greater dry weight than those of the sod culture (362 kg/10a). Higher N concentration in cover crops occurred on early seeding time, and estimated N contribution from the cover crops was 16.9 kg/10a, which was 2.6 times greater than those of sod culture. $P_2O_5$ production from the cover crops was the greatest on seeding of October, and $K_2O$ production increased at earlier seeding time.

Objective: Initial consequence of inbreeding is inbreeding depression which impairs the performance of growth, production, health, fertility and survival traits in different animal breeds and populations. The effect of inbreeding on economically important traits should be accurately estimated. The effect of inbreeding depression on growth traits in sheep has been reported in many breeds. Based on this, the main objective of the present research was to evaluate the impact of inbreeding on some growth traits of Iranian Baluchi sheep breed using quantile regression model. Methods: Pedigree and growth traits records of 13,633 Baluchi lambs born from year 1989 to 2016 were used in this research. The traits were birth weight, weaning weight, six-month weight, nine-month weight, and yearling weight. The contribution, inbreeding and co-ancestry software was used to calculate the pedigree statistics and inbreeding coefficients. To evaluate the impact of inbreeding on different quantiles of each growth trait, a series of quantile regression models were fitted using QUANTREG procedure of SAS software. Annual trend of inbreeding was also estimated fitting a simple linear regression of lamb's inbreeding coefficient on the birth year. Results: Average inbreeding coefficient of the population was 1.63 percent. Annual increase rate of inbreeding of the flock was 0.11 percent (p<0.01). The results showed that the effect of inbreeding in different quantiles of growth traits is not similar. Also, inbreeding affected differently on growth traits, considering lambs' sex and type of birth. Conclusion: Quantile regression revealed that inbreeding did not have similar effect on different quantiles of growth traits in Iranian Baluchi lambs indicating that at a given age and inbreeding coefficient, lambs with different sex and birth type were not equally influenced by inbreeding.

One of the characteristics of the neurons that distinguishes them from other cells is their complex and polarized structure consisting of dendrites, cell body, and axon. The complexity and diversity of dendrites are particularly well recognized, and accumulating evidences suggest that the alterations in the dendrite structure are associated with many neurodegenerative diseases. Given the importance of the proper dendritic structures for neuronal functions, the dendrite pathology appears to have crucial contribution to the pathogenesis of neurodegenerative diseases. Nonetheless, the cellular and molecular basis of dendritic changes in the neurodegenerative diseases remains largely elusive. Previous studies in normal condition have revealed that several cellular components, such as local cytoskeletal structures and organelles located locally in dendrites, play crucial roles in dendrite growth. By reviewing what has been unveiled to date regarding dendrite growth in terms of these local cellular components, we aim to provide an insight to categorize the potential cellular basis that can be applied to the dendrite pathology manifested in many neurodegenerative diseases.

Small ruminants form an important economic and ecological niche in small farm systems and agriculture. Their current low level of contribution is dismal, and is not commensurate with the potential capacity for higher levels of production. The context for productivity enhancement and increased socio-economic contribution relates to large sizes of small ruminant populations; wide distribution across various agro-ecological zones and production systems; and diversity of breeds, where 66% of all goat and 57% of sheep breeds in Asia are found in China, India and Pakistan. The advantages and disadvantages of small ruminants over larger ruminants are enumerated with reference to adaptation and environment, small size, production systems and products and interactions with the environment. Discussion focuses especially on efficiency of meat production and niche markets for higher-priced goat meat, and inefficient marketing systems given an estimated 40-45% loss of income to farmers presently. Increasing the quantity of meat produced is related to live weight and the total number of animals at Slaughter, which in turn, depend on the total number of offsprings weaned and lifetime productivity. At the national level, priority attention is essential to build up numbers in concerted breeding programmes, selection for efficiency of reproduction and meat production, and improvements to make traditional markets and marketing systems to respond to the changing environmental and consumer preferences. Post-production systems are neglected and improvements are associated with collection, handling, marketing, slaughter facilities and consumer requirements. Potential opportunities to expand and benefit from integrating small ruminants into annual and perennial cropping systems remain largely unexplored. Important development imperatives include choice of species and better use of available breeds, appropriate production systems that match available feed resources, and linkages between production, products and by-products to markets. Affirmative action is necessary, backed by official policy support, institutional commitment and increased resource use, that can target poverty and directly benefit the poor, and shift subsistence production to a more market-oriented opportunity. These efforts together constitute the challenges for both the owners and producers of small ruminants in the immediate future, as also the will to accelerate increased productivity, improve their livelihoods and promote rural growth.

On the process of Korean last half century's condensed economic growth, the contribution of quality management was very important. But if we continued the way in which U.S.A. developed and Japan revised, we would not be able to catch up the developed country. This paper says allegedly that we'd better introduce Korean Quality Management system, which is based on Korean traditional thought.

In this study, the LINC project is finished and a new LINC+ has begun. For the settlement of mutual cooperation in universities and corporations, the main agenda of LINC+ project, this research attempts to find factors that are important to industries rather than the measurement of performance closely related to universities. From the companies' perspective, it is not easy to measure how much they are benefiting from mutual cooperation, although there are quantitative performance determinants such as sales, employment and export growth. Therefore, while estimating the satisfaction of industrial-educational cooperation and simultaneously estimating the satisfaction's effect to the development of companies, we try to estimate the contribution of satisfaction towards company development through subjective indicators. Through these efforts, we will raise the credibility of government policies through the cultivation of talented individuals who are customized to the industry through the cultivation of "Industry-Leading Universities" that we intend to pursue through the implementation of LINC+ business, and small and medium enterprises. Innovative support and the cooperation of industry-universities will increase job creation and ensure consistent industry. We will contribute to the mutual development of universities and industries.

The agricultural sector has an important contribution to the economic development of Vietnam in particular and other countries in general. The growth of enterprises in the industry is an important bridge in promoting the economic development of the country. Currently, the policies of the Government of Vietnam always create favorable conditions for enterprises to conduct business, especially enterprises in the agricultural sector. The study aims to assess factors influencing the profitability of listed firms in Vietnam's stock market. Using 40 enterprises in the agricultural industry listed on the Ho Chi Minh City Stock Exchange and the Hanoi Stock Exchange and using advanced econometric modeling, dealing with defects in the regression model, the research results show that large-scale firm has higher economic efficiency than small-scale firm. In addition, a firm with higher use of loan capital is associated with a more efficient firm, reflected in the relatively good debt management ability of enterprises in the agricultural sector. Adversely, growth and age do not have any impact on firm performance. Macroeconomic factors do not impact profitability. Finally, the study has some policy implications for developing agricultural businesses in the case of Vietnam.
