Adipose tissue deposited within muscle fibers, known as intramuscular fat (IMF or marbling), is a major determinant of meat quality and thereby affects its economic value. The biological mechanisms that determine IMF content are therefore of interest. In this study, 48 genes involved in the bovine peroxisome proliferator-activated receptor signaling pathway, which is involved in lipid metabolism, were investigated to identify candidate genes associated with IMF in the longissimus dorsi of Hanwoo (Korean cattle). Ten genes, retinoid X receptor alpha, peroxisome proliferator-activated receptor gamma (PPARG), phospholipid transfer protein, stearoyl-CoA desaturase, nuclear receptor subfamily 1 group H member 3, fatty acid binding protein 3 (FABP3), carnitine palmitoyltransferase II, acyl-Coenzyme A dehydrogenase long chain (ACADL), acyl-Coenzyme A oxidase 2 branched chain, and fatty acid binding protein 4, showed significant effects with regard to IMF and were differentially expressed between the low- and high-marbled groups (p<0.05). Analysis of the gene co-expression network based on Pearson's correlation coefficients identified 10 up-regulated genes in the high-marbled group that formed a major cluster. Among these genes, the PPARG-FABP4 gene pair exhibited the strongest correlation in the network. Glycerol kinase was found to play a role in mediating activation of the differentially expressed genes. We categorized the 10 significantly differentially expressed genes into the corresponding downstream pathways and investigated the direct interactive relationships among these genes. We suggest that fatty acid oxidation is the major downstream pathway affecting IMF content. The PPARG/RXRA complex triggers activation of target genes involved in fatty acid oxidation resulting in increased triglyceride formation by ATP production. Our findings highlight candidate genes associated with the IMF content of the loin muscle of Korean cattle and provide insight into the biological mechanisms that determine adipose deposition within muscle.

This survey is focused on analyzing amenity resources for the purpose of offering basic sources for balanced development and the activation of sightseeing in Anmyen-island which has superior landscape resources and the result follows as this. 1. As a result of selecting "Amenities characterized in isles" and comparing their applications in order to choose amenity resource surveying method which is suitable for the isle districts where beaches, tidelands, fishing villages and so on are formed, it was considered that the surveying method of the rural amenity resource in the Korean Society of Rural Planning could be properly used. 2. In spite of a variety of amenity resources besides ten beaches, Anmyeon-island has been developed only focused on beaches. Therefore, it is highly recommended to develop new sightseeing courses which connect beaches with adjacent amenity resources such as theme programs. 3. It proved that compared with Anmyeoneup, Gonammyeon has superior landscape resources and higher special product rates, which is caused by the fact that it doesn't have various kinds of amenities. As diverse fish inhabit the sea and tidelands in Gonammyeon, it is beneficial for activating sightseeing tours to develop fishing village experiencing programs including going fishing. 4. Anmyen-island can be divided into East district and West distict by the national road no,77 and two districts have different distributional features of sightseeing amenity resources. In the west district, amenity resources such as coastal sightseeing routes, large event halls, and resorts have been activated in addition to fourteen beaches which have already been developed while the amenity resources in the east like fishing villages, tidelands, and salt fields have not been activated. Accordingly, for activating balanced sightseeing development in Amyeon-island, it is required to make plans which can incorporate the east amenity resources of sea sightseeing and the west amenity resources of fishing village experiencing programs. As a way, constructing sightseeing routes connecting the west and the east district or making a detour lane connecting beaches in the west, Anmyeon pine trees in the center, and fishing villages in the east.

The purpose of this study was to develop the strategy on activation of village by forest healing. Researcher conducted the questionnaire survey for forest healing village development to classify the mountain's characteristics by the three factors(linkage resource, program, facilities). In result, village characteristics were divided into two types: single element outstanding type(resource), complex element outstanding type(resource+program, resource+facilities). The development of forest healing village have to focused on the forest healing service recipient and mountain village characteristics. In conclusion, relationship between forest healing recipient and mountain characteristics was as follows: single type (resource) - public; complex type (resource+program) - chronic disease, social vulnerable people; complex type (resource+facilities) - severe disease. The detailed guideline for forest healing village needs to be established according to the mountain characteristics.

The purposes of this study were to investigate the realities of community participation of young farmers and to suggest measures to activate community participation. The data were collected from 234 young farmers from rural Korea. With SPSS 13.0 program for Windows, Frequency, t-test, ANOVA, LSD for post-hoc interpretation and Factor Analysis were employed to analyze the data with statistical significance level of .05. The main results of the study and suggestions were as follows: 1) Young farmers were more likely to participate in watching television on community, discussion with others and internet search for community, while, rural youths were less likely to participate in contacting government and parliament. 2) Difficulties of community participations of young farmers were lack of time and insufficient information about participatory activities. The study suggested that young farmers should get more opportunities to participate in diverse types of active opportunities and practical information.

Green tourism is a stay-flow activity between people in urban and rural area, using a natural view, tradition, and life in agricultural area. And green tourism provides rest, recreation, and new experience fur people living in urban area as well as opportunities to increase income for people in rural area. In recently, amenity is rapidly rising as a main factor fur a regional competitiveness. Boseong county shows a typical agriculture industrial structure with a weak independent base, but has a beautiful tea fields in full seasons. Boseong county is making an effort to activate the regional economy, but the result fall short of one's expectation. Several methods to activate the green tourism of Boseong county are as follows: i) introduction of specialized theme relating Boseong green tea; ii) provision of information regarding tourist resort and development of experience-program related to green tea business; iii) establishment of a sales network of products through accommodations in private houses; iv) establishment of networks among regions to achieve systematic sales of tourist experience, accommodations in private houses, and local speciality simultaneously.

Auxin is a group of small natural and synthetic molecules having diverse regulatory functions in plant growth and development. In this review, two auxin binding proteins identified by biochemical experiments to measure their auxin binding activities and biochemical functions are described. ABP1, a 22 kDa auxin binding protein, shows strong auxin binding affinity and possibly plays an important role in plant development, although its biochemical function are still unclear. ABP57, a 57 kDa soluble protein from rice shoots, has both of IAA binding activity and the plasma membrane proton pump activation. Although it is yet to be accomplished, the improvement of agronomic traits using auxin binding proteins is worth to be considered, since auxin is known to be related to such a diverse crop traits.

Southern blight, caused by the soil-borne fungus Sclerotium rolfsii, is a serious disease that affects many economically important crops. In this study, we selected Bacillus subtilis GJ6-14, from a total of 260 strains, to control Southern blight in pepper plants. In both seedling and plant tests, GJ6-14 significantly suppressed disease incidence and severity compared to control, furthermore, GJ6-14 demonstrated efficient colonization in the rhizosphere by maintaining the population from log 5.41 to log 3.92 in the pathogen-inoculated plants, indicating its potential as a biocontrol agent. Molecular analysis revealed up-regulation of defense-related genes, such as a 7.6-fold increase in LOX1 and 15.5-fold increase in PR1, at 72 hr after inoculation of S. rolfsii in GJ6-14-treated plants, suggesting activation of plant defense mechanisms. Overall, our findings highlight the promising role of B. subtilis GJ6-14 as a potential biocontrol agent in sustainable management of Southern blight in pepper plants.
