Birth weight and subsequent weight gain is of critical importance in the survival and performance of piglets on a commercial swine farm setting. Oropharyngeal microbiome could influence immunity, and feeding behavior thus impacting health and weight gain. We used 16S rRNA gene sequencing to profile the composition and predicted metabolic functionality of the oropharyngeal microbiota in 8 piglets (4 with a birthweight ≤ 1.0 kg and 4 with a birthweight ≥ 1.7 kg) at 11, 26, and 63 days of age. We found 9 genera that were significantly associated with average daily gain (ADG) at 11 days (false discovery rate, FDR < 0.05) and 26 days of age (FDR < 0.1), respectively. The microbial functional profile revealed several pathways associated with ADG (FDR < 0.05). Among these, pathways related to degradation of catechols showed a positive association with ADG at 11, 26, and 63 days of age, implying a potential to breakdown the host-derived catecholamines. We also noted that pathways related to the biodegradation of nucleosides and nucleotides increased with ADG during the pre-weaning phase, while those involved in their biosynthesis decreased. Our findings provide insights into the oropharyngeal microbial memberships and metabolic pathways that are involved in a piglet's weight gain. Thus, providing a basis for the development of strategies aimed at improving weight gain in pigs.

Global climate change can be solved only through international cooperation. Climate change can be caused by natural and anthropogenic causes. An important policy responding on the climate change is to reduce the emission of climate change-affecting substances caused by anthropogenic causes. This research was conducted to suggest the direction of Korea's LULUCF(Land Use-Land Use Change and Forestry) policy by comparing Germany's LULUCF policy, which is considered as a good case for establishing the EU's greenhouse gas reduction response policy. Germany's LULUCF policy concerns with various sectors for synergy effects, while Korea's LULUCF policy is biased towards the forest sector. Although Korea's LULUCF policy focuses on forests, basic research is still insufficient and the linkage with existing environmental policies is low. Therefore, Korea's LULUCF policy needs more expansion into many different sectors such as agricultural, environmental, and other fields.

Natural gas is the world's fastest-growing fossil fuel, with consumption increasing from 113 trillion cubic feet(Tcf) in 2010 to 185Tcf in 2040. While conventional natural gas streams from the earth relatively easily, unconventional gas finds are more difficult to develop and more costly to produce. Right now, there are six main types of unconventional gas, including deep gas, gas-containing shale, coalbed methane(CBM), geopressurized zones, Arctic and subsea hydrates, and tight gas. Tight gas refers to natural gas reservoirs locked in extraordinarily impermeable, hard rocks(sandstone, siltstone or carbonate sedimentary rocks). In this study, we analyzed total 375 papers(2000-2014) of tight gas by country, institution, international cooperation etc.

The purpose of this study was to compare the visitor's satisfaction factors and causal relationships among the 2010, 2012, and 2016 Korea International Exhibition of Machinery Equipment, Science and Technology for Agriculture. A total of 17 variables to evaluate the level of satisfaction were divided into three factors: contents, publicity and guidance, and environment of convenience facilities. The results were as follows. First, from 2010 to 2016, the Expo showed quantitative and qualitative growth in terms of the number of visitors, firms, and performances. Second, in 2016, the number of visitors aged below 20, foreigners, and new visitors increased year-on-year. Third, the contents, publicity and guidance, and satisfaction were higher than in the last two cases, but the environment of convenience facilities showed no difference among the years. In addition, the revisiting intention in 2012 was higher than that of 2016. Lastly, all three factors had a significant impact on the level of satisfaction in 2016, but publicity and guidance and environment of convenience facilities in 2010 and 2012 were not significant factors on satisfaction. Furthermore, the satisfaction of all three expos was confirmed to be a significant factor for the visitor's revisiting intention.

The objective of this study was to investigate the influence of ambient temperatures on carcass characteristics of lambs fed concentrate diets with or without $NaHCO_3$ supplementation. A slaughter study was carried on 12 male Black Belly Barbados lambs randomly drawn from a growth trial (35 weeks). The lambs were divided into four equal groups and allotted in a $2{\times}2$ factorial design. The lambs were allotted at random to two dietary treatments of a basal diet (35:65 roughage:concentrate) or basal diet supplemented with 4% $NaHCO_3$ at different ambient temperatures ($20^{\circ}C$ and $30^{\circ}C$) in an environment controlled chamber for 10 days. Lambs were slaughtered for carcass evaluation at about 262 days of age (245 days of growth trial, 7 days adaptation and 10 days of experimental period). Ambient temperature had significant (p<0.05, p<0.05, p<0.01, and p<0.001) effects on meat color from the ribeye area (REA), fat, leg and longissimus dorsi muscles with higher values recorded for lambs in the lower temperature group than those from the higher ambient temperature group. Significant differences (p<0.05) in shear force value ($kg/cm^2$) recorded on the leg muscles showed higher values (5.32 vs 4.16) in lambs under the lower ambient temperature group compared to the other group. Dietary treatments had significant (p<0.01, p<0.01, and p<0.05) effects on meat color from the REA, fat, and REA fat depth ($cm^2$) with higher values recorded for lambs in the $NaHCO_3$ supplementation group than the non supplemented group. Similarly, dietary treatments had significant differences (p<0.05) in shear force value ($kg/cm^2$) of the leg muscles with the $NaHCO_3$ groups recording higher (5.30 vs 4.60) values than those from the other group. Neither ambient temperature nor dietary treatments had any significant (p>0.05) effects on pH, and water holding capacity on both muscles. These results indicated that $NaHCO_3$ supplementation at low ambient temperatures had caused an increase in carcass characteristics leading to significant effect on meat quality.

Objectives: South Korea's occupational safety and health legislation appears on the surface to have stronger regulations than any other country, but it is criticized for having many problems when viewed from the perspective of the effectiveness and universality of these regulations. Therefore, it is necessary to consider the validity of the regulatory content and the methods for contract work in South Korea. Methods: The main issues in contract work are compared and analyzed in terms of the occupational safety and health laws systems in South Korea and other developed countries. Based on this, problems related to contract regulation are derived from the perspective of legal policy studies. In addition, effective improvement measures for the derived problems will be proposed. Results: Other developed countries impose obligations suitable for the status and role of persons who entrust work in consideration of the fact that they do not directly manage risks and in terms of the effectiveness of industrial accident prevention. These countries generally impose obligations such as management of facilities and machinery, cooperation and coordination with subcontractors, cooperation and coordination obligations between subcontractors, and guidance obligations on a person who entrusts a work. Conclusions: It is difficult to achieve effectiveness in preventing accidents with based on unreasonable regulations that do not conform to safety principles or legal theory. Regulations on contract work need to be converted to rational cogent regulations based on science and rationality, not ideology and emotion. To this end, the legal system for contract work must have international universality.

This research was conducted to make suggestions for the promotion of research activities in the field of animal resources sciences, and we evaluated the research funding trend and the present status of research funding offered by KOSEF in this field. Comparative portion of the number of research projects and grants in this field to other fields has a tendency to be decreased year by year except recent few years. Researchers in this field have received more research funding from the group-based program than from the individual-based program. Also, they have received less money(per project) than did researchers in the fields of general agricultural sciences and other science and technology. Researchers in this field ranges from 43 to 51 years of age and showed 48 years of average age. It was found that researchers who has been funded in the field of animal resources sciences have showed tendency of publication of more articles to SCI journals in recent 5 years. The strong points of the animal resources of agricultural sciences field in South Korea include: lots of researchers, the establishment of research infra-structure, the excellence in research competitiveness and technology level. However, its weaknesses are: a lack of leadership in relevant societies and institutes, a predicted shortfall of researchers in the next generation and insufficient research productivity. The opportunities include: increasing the importance of the biotechnology industry, activating international cooperation researches and exploring the multitude of possible research areas to be studied. However, some concerns still exist, such as threats from developed countries for the government to open the agricultural market, the reduction of the number of full-time farms and intensification of needs for economic and social effects. The diverse actions and systems based upon the strongpoint, weakness, opportunity and threats above-mentioned are required to encourage research activities in the field of animal resources of agricultural sciences in Korea In addition, researchers in this fields would make an effort to keep pace with international society as well as domestic demands.
