With the launching WTO, the world economy has been changing new competitive environment. Agricultural exports should be pursued actively in the market of opening era to develop the foreign agricultural product market and to improve the domestic agribusiness quality and strengthen its competitiveness. The purpose of this is paper is to understand agricultural export status of Korea to detect challenges and matter for improvement, to find new measures of export strategy for the foreign market, recent emerging export promotion with high potential growth, and to increase Korea agricultural export to new world market by using a new method. The profit and loss status is volatile since the agricultural export is in its infancy. However, we have learned lessons from previous success and failure that prior analyzing of agricultural export feasibility, phased-in expansion of agri-food export volume, connection of agri-food export and agri-food market policy. In relation to this, this paper introduces Efficient and Effective Utilization of Communal Facilities in agri-food export. Consequently, First, Export promotion scheme for agri-food is to precise analysis of import countries and to collection agri-food export procedure and agri-food market system. Second, In order to expand export agricultural products to new world market, we need to direct 3rd support program to enhancing competitiveness in expanding export of agricultural export.

Greenhouse-gas emission factors are widely used to estimate emissions arising from a defined unit of a specific activity. Such estimates are used both for international reporting to the United Nations Framework Convention on Climate Change (UNFCCC) and for myriad national and sub-national reporting purposes (for example, European Union Emissions Trading Scheme; EU ETS). As with the other so-called 'Kyoto protocol GHGs', the Intergovernmental Panel on Climate Change (IPCC) provides a methodology for national and sub-national estimation of $N_2O$ emissions, based on the sector from which the emissions arise. The objective of this study was to develop a integrated emission factor to estimate the direct $N_2O$ emission from an agricultural field cultivated with the red pepper, soy bean, spring cabbage, autumn cabbage and potato in 2010~2012. Emission factor of $N_2O$ calculated using accumulated $N_2O$ emission, N fertilization rate, and background $N_2O$ emission over three year experiment was $0.00596{\pm}0.001337kg$ $N_2O-N(N\;kg)^{-1}$. More extensive studies need to be conducted to develop $N_2O$ emission factors for other upland crops in the various regions of Korea because $N_2O$ emission is influenced by many factors including climate characteristics, soil properties, and agricultural practices.

This study establishes a safe and healthy farm certification system for Korean farmers and presents the certification system and assessment items. Existing certification systems for safety and health were compared through a review of local and international studies as well as an examination of advanced examples. Then the certification system and assessment items were objectively verified through an expert evaluation process. As a result, four domains of certification participation, implementation, certification evaluation, and post management were identified as components of the certification system. For assessment measures, 6 categories, 21 factors, and 96 items were derived. The results are expected to be used as basic data in establishing a foundation for the implementation and operation of a certification system appropriate for distinct characteristics of the Korean agricultural sector.

The food source of white-spotted flower chafer, Protaetia brevitarsis is important to economical performance. The P. brevitarsis larva were feed by mulberry and oak fermented sawdust. The effect of additional additives, Korean black raspberry (called bokbunja) marc and blueberry marc to fermented sawdust feed on the development and oviposition characteristics were investigated. The development periods of P. brevitarsis was decreased from 165.7 d to 40.0 d (mulberry sawdust) and 169.3 d to 39.0 d (oak sawdust), but the survival rate of larva was not affected by the addition of Korean black raspberry marc to fermented sawdust. However, blueberry marc addition to the fermented sawdust did not significant effect on the development period and survival rate of P. brevitarsis. The percentage of larva weight over 2.5 g was tend to increase by addition of Korean black raspberry marc and/or blueberry marc. The number of oviposition was also tend to increase by adding additional feed to sawdust but there was no significant different.

Silkworms have recently attracted attention as healthy functional foods. Different varieties of silkworms have functional differences; thus, there is an emerging need for variety identification. In this study, we sequenced complete mitochondrial genomes (mitogenomes) of ten government-recommended silkworm varieties (BaekHwang, BaekOk, DaeBaek, DaeBak, DaeHwang, GoldenSilk, HanSaeng, JooHwang, KumKang, and KumOk). Comparison of these sequences allowed us to select the single nucleotide polymorphisms (SNPs) in 34 sites that are specific to six silkworm varieties: 13 in DaeBak, 8 in GoldenSilk, 9 in KumKang, 2 in BaekHwang, 1 in BaekOk, and 1 in DaeHwang. Among these each one SNP per variety was amplified by preparing variety-specific primers and then using tetra-primer amplification refractory mutation system PCR (T-ARMS-PCR). As a result, it was possible to identify these six varieties among the ten silkworm varieties, evidencing that SNPs developed from mitogenomes are useful marker for the discrimination of genetically closer silkworm varieties.

This study was performed to investigate the temperature-dependent development, longevity and oviposition of an indigenous larval parasitoid, Meteorus pulchricornis, on tobacco cutworm, Spodoptera litura. M. pulchricornis were reared at nine constant temperatures between 15 and $35^{\circ}C$. The developmental times of each three developmental stage decreased from 38.7 to 16.3 d between 15 and $30^{\circ}C$. However, M. pulchricornis showed longer developmental time at $32.5^{\circ}C$ (9.5, 7.7 and 17.2 days for each three developmental stage) than at $30^{\circ}C$ (8.9, 7.3 and 16.3 days for each three developmental stage). Immature M. pulchricornis could not develop any more at $35^{\circ}C$. The lower developmental threshold estimated by linear regression equation for the egg to cocoon, cocoon to adult emergence and egg to adult emergence were 5.1, 4.6 and $4.5^{\circ}C$. The thermal constant for each of the three stages were 217.2, 176.2 and 403.8 degree-days, respectively. When no food or 50% honey solution as a food source is provided for M. pulchricornis, the parasitoid survived for 8.3 and 55.9 days at $25^{\circ}C$, respectively. M. pulchricornis females laid 5.2 eggs daily and total of 131.6 eggs at $25^{\circ}C$ until it died. Peak age-specific fecundity was observed on $14^{th}$ day (9.6 cocoons) after parasitoid emergence and gradually decreased thereafter.

Agricultural extension services in Korea are faced with increasing demands for more efficient production and managerial technology according to globalization and free trade system. At the same time, three steps of organizational restructuring in 1998 and 1999 resulted in decreased number of organization and manpower, thus, resulting confusion in implementing extension services. To cope with the international and national challenges, Korean agricultural extension services should try paradigm shift including the followings; 1. To establish identity of agricultural extension services in Korea through making laws and regulations in terms of concept, roles, principles. implementation and methods. 2. To implement vitalizations plan through enhancement of national extension service such as food production. raising local specialty products for domestic consumption and producing strategic agricultural products for export. expanding capability of rural women, increasing opportunity for management consultation, supporting digital technology information, and promoting morale and capability of extension educators. 3. To reform agricultural extension system through adjusting the functions of extension service of the Rural Development Administration, regionalizing city and county extension center to provincial level, and changing the status of directors of extension centers from city /county to national government.

The purpose of this study is to analyze the effectiveness of an agriculture and rural development ODA project in southern Nepal's Terai region to improve food security, and to suggest appropriate project approaches to improve food security. The subject of the analysis is the KOICA-funded 'Inclusive Rural Development project', and a framework for analyzing food security was established based on the FAO's four pillars of food security, and indicators were proposed to measure the food security of project farmers. The data for this study were obtained from a survey of project beneficiary farmers and their control group, and the effects of the project on food security were measured using a a t-test analysis, difference-in-difference analysis, propensity score matching-linear regression combined model (PSM-OLS) and a propensity score matching-difference-in-difference combined model(PSM-DID). The results showed that, in general, the ODA project treatment group had significant improvements in each of the four pillars of food security (food availability, access, utilization, and stability). In addition, cooperative membership had a positive impact on food security improvements, and there were also differences in outcomes among different ethnic groups in the Terai region. The implications of this study are that the Korean government's ODA policy should set aside the food security sector and incorporate food security indicators to contribute to the improvement of food security in ODA partner countries, and that agricultural and rural development ODA projects should include food security indicators as performance indicators in their pre-planning to contribute to securing food security for vulnerable groups as food insecurity is higher among vulnerable groups.

The Joseon Dynasty lasted for 618 years, from 1392 to 1910, and is regarded as one of the development periods of Korea in various areas, including politics, culture, economy, and society. During this period, the government undertook various measures to try to change the state of the economy and generally transform people's living standards. These were some of the strategies founded on Confucianism, which focused on the right way to govern and manage the economy to attain prosperity for the society. The present study explores government development strategies for improving the economy in Joseon Dynasty period using comprehensive literature analysis via Kci, Scopus, Web of Science databases. Indeed, agricultural transformations during the Joseon dynasty clearly show that knowledge and innovation were critical for encouraging agricultural growth. Therefore, today's South Korean government can implement technological advancement and research to improve its agricultural value chain and food security. Many farmers lack knowledge about improved methods of practicing agriculture or have inadequate capital to invest in research and development; these issues can be dealt with by the relevant government agencies putting in place necessary policies and creating awareness through educational programs and articles.
