This paper investigated the satisfaction of agro-healing and analyzed its willingness to participate in agro-healing in the future. First, a survey of intentions to participate in agro-healing found that the ratio of participation was 55.6% (125 people). It is analyzed that more than half of teenagers who have experienced agro-healing programs are willing to participate again. Second, a survey of satisfaction with agro-healing showed the highest improvement in agricultural awareness, including increased public interest value of agriculture. This can be seen as a way to raise public awareness of agriculture, as well as the effects of mental and physical health recovery, social integration contributions, and social safety contributions. Third, an analysis of the effect of awareness on the willingness to participate in agro-healing showed that the less significant it was, the higher the awareness, the higher the willingness to participate. In other words, various information delivery means, such as public relations measures, should be prepared to raise awareness of agro-healing. Fourth, it can be seen that those with low satisfaction with expected effects such as health recovery, social safety, social integration, and improved agricultural awareness have a clear difference in their willingness to participate in the future. In other words, the higher the satisfaction level of the agro-healing program, the higher the willingness to participate in the agro-healing industry in the future.

Objective: The inhibitory effects of dietary antioxidants, diallyl disulfide (DADS) and quercetin, in marinade were investigated on the formation of carcinogenic polycyclic aromatic hydrocarbons (EPA priority 16 PAHs) in grilled pork. Methods: The formation of PAHs in grilled sirloin pork with different marinades after charcoal-grilling for 2 min/side were evaluated using high performance liquid chromatography with a photodiode array detector (HPLC-DAD). Results: Compared with the control marinade treatment (without antioxidant), the addition of DADS (500 mg/kg meat sample) in marinade significantly decreased benzo[a]pyrene (BaP) (100%) and heavy PAHs (84%) in charcoal-grilled pork, while the addition of quercetin at the same concentration could reduce 23% and 55% of BaP and heavy PAHs, respectively. Conclusion: The results of this study suggested that the addition of DADS in the marinade could be important in decreasing the levels of PAHs in grilled meat.

Nowadays, agro-firms are confronted with competition from global suppliers in both domestic and export markets. Such competition in sustainable agro-operations is expected to intensify. The survival of these firms in developing countries urgently requires a significant transformation to be competitive. This paper discusses the rationale of adopting a national innovation (NI) approach from an industry-wide perspective. In order to attain sustainable agro-operations in developing countries, the approach stresses appropriate scientific and technological applications and effective linkages of technology transfer via the network between public and private institutions, universities and other research institutions. Central to this approach is the development of the agro-industrial sector whereby agri-chains are formed. An illustrated case of the NI approach is presented with respect to a small island developing state, the Republic of Trinidad and Tobago.

농학계열 대학의 역할에 대한 논의들은 주로 농업의 본원적 기능인 농산물생산과 사회적 필요에 의해 새롭게 중요성이 강조되는 기능들로 구분되는데, 녹색혁명과 농업인 노령화가 심한 상황에서 농학계 학문은 현상유지 정도만이 필요한 분야로 바라보는 시각이 강하다. 그러나 농업은 전통적인 농산물 생산중심에서 벗어나고, 그 개념과 내용이 확장되면서, 농학적 배경지식이 필요한 분야는 보다 세밀해지고 확대되고 있다. 하지만 대학평가의 가늠자로 평가받는 취업률 조사에서 농학계열 대학의 역할이 반영된 분야는 영농인 육성으로 보는 시각이 강하다. 영농업종사자를 제외한 농산업부문은 농학계열 학문분야와 다른 모든 학문분야가 한데 묶인 공통의 일반산업부문 범주로 구성되어, 농산업부문에 취업을 해도 전공과 관련 없는 분야에 취업한 것으로 볼 수 있는 문제가 있다. 이러한 배경에서 본 연구는 농학계열 대학 졸업생의 농산업분야 취업상황을 중심으로 인력육성측면에서 농학계열 대학의 갖는 의의를 살펴보았다. 농학계열 학문연구 분야는 국가과학기술표준분류 중분류 16개 분야로 구분하고, 취업분야는 산업연관부문 통합소분류 168개를 활용하여 전국 37개 대학 220개 학과를 대상으로 2013년 졸업생의 취업상황을 조사하였다. 조사결과 전체 취업자 3명 중 1명인 33.0%가 농산업분야에 진출하고 있었고, 이 중 3.6%가 농산업분야에 창업하고 있었다. 특히 영농종사자의 경우 2013년 국내 대학졸업자의 0.1%만이 취업하는 것으로 조사되었으나, 조사결과는 13.3%로 농업인 육성에 농학계열 대학의 기여가 큼을 확인할 수 있었다. 연구결과를 통해 볼 때, 취업률 조사방식의 문제로 제대로 역할을 평가받지 못하고 있는 것으로 보이나, 농학계열 대학의 농업, 농산업분야에 대한 기여를 확인할 수 있었다.

Importance: Over the past decade, catfish farming has increased in Southeast Asia. However, there has been no existing for pharmacokinetic data in the hybrid catfish (Clarias macrocephalus x C. gariepinus). Objective: This study was designed to evaluate the pharmacokinetic characteristics of oxytetracycline (OTC) in the hybrid catfish, following single intravascular (IV) or oral (PO) administration at a single dosage of 50 mg/kg body weight (BW). Methods: In total, 140 catfish (each about 100-120 g BW) were divided into two groups (n = 70). Blood samples (0.6-0.8 mL) were collected from ventral caudal vein at pre-assigned times up to 144 h (sparse samples design). OTC plasma concentrations were analyzed using high-performance liquid chromatography-photodiode array detector. Results: The pharmacokinetic parameter of OTC was evaluated using a non-compartment model. OTC plasma concentrations were detectable for up to 144 and 120 h after IV and PO, respectively. The elimination half-life value of OTC was long with slow clearance after IV administration in hybrid catfish. The average maximum concentration value of OTC was 2.72 ㎍/mL with a time at the maximum concentration of 8 h. The absolute PO bioavailability was low (2.47%). Conclusions and Relevance: These results showed that PO administration of OTC at a dosage of 50 mg/kg BW was unlikely to be effective for clinical use in catfish. The pharmacodynamic properties and clinical efficacy of OTC after multiple medicated feed are warranted.

Objective: Numerous studies have indicated that the apoptosis and proliferation of granulosa cells (GCs) are closely related to the normal growth and development of follicles and ovaries. Previous evidence has suggested that miR-126-3p might get involved in the apoptosis and proliferation of GCs, and phosphatidylinositol 3-kinase regulatory subunit 2 (PIK3R2) gene has been predicted as one target of miR-126-3p. However, the molecular regulation of miR-126-3p on PIK3R2 and the effects of PIK3R2 on porcine GCs apoptosis and proliferation remain virtually unexplored. Methods: In this study, using porcine GCs as a cellular model, luciferase report assay, mutation and deletion were applied to verify the targeting relationship between miR-126-3p and PIK3R2. Annexin-V/PI staining and 5-ethynyl-2'-deoxyuridine assay were applied to explore the effect of PIK3R2 on GCs apoptosis and proliferation, respectively. Real-time quantitative polymerase chain reaction and Western Blot were applied to explore the regulation of miR-126-3p on PIK3R2 expression. Results: We found that miR-126-3p targeted at PIK3R2 and inhibited its mRNA and protein expression. Knockdown of PIK3R2 significantly inhibited the apoptosis and promoted the proliferation of porcine GCs, and significantly down-regulated the mRNA expression of several key genes of PI3K pathway such as insulin-like growth factor 1 receptor (IGF1R), insulin receptor (INSR), pyruvate dehydrogenase kinase 1 (PDK1), and serine/threonine kinase 1 (AKT1). Conclusion: MiR-126-3p might target and inhibit the mRNA and protein expressions of PIK3R2, thereby inhibiting GC apoptosis and promoting GC proliferation by down-regulating several key genes of the PI3K pathway, IGF1R, INSR, PDK1, and AKT1. These findings would provide great insight into further exploring the molecular regulation of miR-126-3p and PIK3R2 on the functions of GCs during the folliculogenesis in female mammals.

The main purpose of this study is to substantiate the theoretical and methodological foundations of the organizational and economic mechanism of development of the agro-industrial complex in modern conditions. Organizational and economic mechanism is presented as a complex organizational structure of the system type, which is aimed at performing specific functions, the characteristic feature of which is the constant support of process changes without which the organizational and economic mechanism can not exist. There are four components of the agro-industrial complex, represented by agriculture and the national economy, which ensure its operation, including industry, processing of agricultural products, its storage and transportation, sale and repair and maintenance of agricultural machinery and more. It is proved that the organizational and economic mechanism of development of agro-industrial complex in modern conditions it is expedient to consider: from the point of view of system and process approaches; as a set of economic levers and organizational measures to influence the agro-industrial complex; constituent components of organizational influence on the development of the complex; a set of components, elements that are integrated into the system of economic relations of the subjects of the agro-industrial complex; a set of purposeful stimulators of agro-industrial complex development. The functions of the organizational component of the mechanism of agro-industrial complex include: redistributive, planning, interaction, control, integration and regulatory functions, the functions of the economic component include consumer, investment and innovation, social, incentive, monitoring functions of the mechanism. The symbiosis of the functions of organizational and economic components ensure the effectiveness of the organizational and economic mechanism of the organizational and economic mechanism through its functionalities as a whole.

Characteristics and properties of gelatin from goat skin pretreated with NaOH solutions (0.50 and 0.75 M) for various times (1 to 4 days) were investigated. All gelatins contained ${\alpha}$-chains as the predominant component, followed by ${\beta}$-chain. Gelling and melting temperatures of those gelatins were $23.02^{\circ}C$ to $24.16^{\circ}C$ and $33.07^{\circ}C$ to $34.51^{\circ}C$, respectively. Gel strength of gelatins increased as NaOH concentration and pretreatment time increased (p<0.05). Pretreatment for a longer time yielded gelatin with a decrease in $L^*$-value but an increase in $b^*$-value. Pretreatment of goat skin using 0.75 M NaOH for 2 days rendered the highest yield (15.95%, wet weight basis) as well as high gel strength (222.42 g), which was higher than bovine gelatin (199.15 g). Gelatin obtained had the imino acid content of 226 residues/1,000 residues and the gelatin gel had a fine and ordered structure. Therefore, goat skin gelatin could be used as a potential replacer of commercial gelatin.
