The insect industry in Korea has been supported by the Act of Fostering and Supporting Insect Industry since 2010. Based on the Act, insect breeders are entitled as farmers. However, the insect industry is not included in the Fundamental Act of Agriculture, Rural Community and Food Industry which defines all concepts, such as agriculture, farmers, and agricultural products. Legally and strictly speaking, there is no method to defense the insect industry when an argument is raised that insect industry is not included into agriculture, so persons who breed insects are not eligible for all agricultural supports and subsidies of the government. Thus, it is necessary to clear the legal status of insect industry by revising the related laws and regulations.

This study was performed to figure out the recognition on forest certification by consumption propensity and socio-economic characteristics of wood cabinet consumers. The mean score of recognition on SFM and FSC showed comparatively low, 2.25 and 2.20(5-point likert scale), from the analysis result on 88 valid questionnaires of 90. The respondents rate of eco and non eco-friendly group formed 80.7% and 18.2%, there is a significant gap between two groups on total questionnaires. The percentage of respondents recognizing on SFM and FSC was about 31% (eco-friendly), 5.6%(non eco-friendly, SFM) and 2.8%(non eco-friendly, FSC) within each group. It showed that the socio-economic characteristics on eco-friendly respondents were higher than the others about more 1.3 times in the married rate, average age and monthly householding income.

The value of a statistical life (VSL) plays a very important role in estimating the benefits of environmental policy. It is used, for example, as a unit of monetization of health benefits resulting from the reduction of air pollutants, which is the basis of cost-benefit analysis of policies. The VSL can be defined as the value that people of each society are willing to pay to reduce the risk of death, so the value should reflect the characteristics of its members. In this study, we apply a choice experiment with 3,081 respondents collected through a web survey were divided into two samples according to the type of questions. Among the various estimates, the most appropriate estimate of the VSL is about 1.3 billion won from 1,528 sample, which is similar to the results of the meta-analysis using estimates from prior studies conducted in Korea. In addition, this study shows that a private prevention program is preferred to reduce the risk of death from cancer rather than a public program.

급격한 도시화와 이로인한 불투수면의 증가는 유역의 물순환을 왜곡시키고 있다. 직접유출의 증가와 침투량 감소로 이어지며 이는 지하수 함유량의 감소와 하천건천화를 유발한다. 환경부는 더 이상의 물순환 왜곡을 막기위해 물환경보전법상의 물순환율을 정의하고 물순환 관리목표를 설정하였으며, 제3차 강우유출 비점오염원관리 종합대책에서 물순환 사업 추진을 위한 소권역 별 우선순위산정을 과제로써 제시하고 있다. 대표적인 물순환 사업은 저영향개발기법 설치이다. 저영향 개발기법은 토지 및 공간을 이용해야하기 때문에 설치비용이 높고 위치선정에 제약이 많으며 유지관리도 어렵다. 이에 물순환 사업에는 단순 불투수면 뿐만아니라 사회, 경제적 요소까지 고려하여야한다. 본 연구에서는 물순환 우선순위를 산정하기위해 불투수면뿐만 아니라 사회, 경제적 요소까지 고려한 종합적인 우선순위를 산정하였다. 유역 물순환 평가를 위해 PSR framework을 이용하였다. PSR framework는 OECD가 개발한 지속가능성 평가 개념이며, Pressure, State, Response 세 가지 요소로 구분해 평가하게된다. PSR framework의 기본 개념은 인간의 활동들이 환경에 압력 (P)를 주고, 이로 인해 자연의 질과 영향 (S)을 미치며, 이에대한 회복을 위해 인식과 행동을 통해 정책과 제도 등을 통해 반응 (R)한다는 것이다. 본 연구에서는 PSR framework의 평가요소 Pressure는 불투수면 및 강우, State는 물순환, 하수관거, 수질, 수생태계, Response는 협력, 인식, 재정, 토지로 구분하여 평가하였다. 최종적으로 불투수면적 감축 대상 소권역('30년 무대책 불투수면적률 25% 이상)소권역에 대하여 최종우선순위를 산정하였다.

In the contingent valuation method (CVM) survey, we employed double-bounded discrete choice (DBDC) question to investigate the willingness to pay (WTP). The estimation results for the bivariate logit model show that respondents are willing to pay 329,256 won per year. The model with covariate variables suggests that the covariate effects help describe behavioral or preference tendencies. Double-bounded models increase efficiency over single dichotomous choice models, because the answers yes-no or no-yes yield clear bounds on WTP.

This study aimed at analyzing the economic value of 'Fuyu' sweet persimmon. For the analysis, the raw data of the latest 9 years were collected from 707 farmers in major sweet persimmon area and from 47 farmers surveyed in the field. These data include receipt price per kilogram, costs, yields per tree, etc. The findings are as follows: The break-even tree age of sweet persimmon was 85 years. The trees reach the maximum harvest at age of 65. 'Fuyu' sweet persimmon's economic value was 10,488 thousand won in income approach, 9,249 thousand won in cost approach, respectively.

The success or failure of aquaculture heavily depends on how effectively to manage aquatic animal diseases. The paper is to estimate the direct effects of economic benefits on aquatic animal disease prevention program using economic surplus analysis. The economic benefits include changes in consumer and producer surplus owing to a reduction effect of aquatic animal mortality and the consumption recovery effect. The annual changes in producer surplus for flounder, rockfish and others cultured is estimated as 2.33 billion won totally (0.87 billion won, 1.01 billion won and 0.45 billion won respectively) and the annual changes in consumer surplus 10.15 billion won totally (6.36 billion won, 1.85 billion won and 1.94 billion won respectively). Therefore, total annual economic benefit is 12.5 billion won.

This study looked into estimation of variance component over swine's economic traits by multiple animal model and maternal effect model using on-farm test data of total 31,455 swine of Duroc, Landrace and Yorkshire species that were born between 2000 and 2008. Heritability by estimated additive genetic effect showed higher than one by maternal genetic effect using multivariate maternal animal model in each trait examined by each breed and most heritability when considering only additive genetic effect in multiple traits animal model was estimated to be higher than one by estimated additive genetic effect in multivariate maternal animal model. In correlation between breeding value by estimated maternal genetic effect and phenotypic value using multivariate maternal animal model, rank correlation and simple correlation of breeding value and phenotypic value by maternal genetic effect also showed low positive correlation or strong negative correlation, which can be considered that if correlation with phenotype were increased properly considering maternal genetic effect in each trait by each breed, even better improvement could be promoted.

가금산업은 국민소득 증가와 식생활의 서구화로 생산액과 소비량이 증가하여 우리 농업에서 매우 중요한 위치를 차지하고 있다. 그러나 세계 각지에서 나타난 고병원성 조류인플루엔자로 인하여 많은 경제적 피해가 발생하고 있으며, 질병의 인체감염으로 인간의 소중한 생명도 위협을 받고 있다. 우리나라의 경우도 예외가 아니어서 그동안 모두 3차례에 걸쳐 고병원성 조류인플루엔자가 발생하여 많은 피해를 입었다. 고병원성 조류인플루엔자의 발생으로 인한 경제적 피해는 가금생산농가에만 국한되는 것이 아니다. 질병 발생으로 인한 경제적 피해는 생산농가와 직간접적으로 연관된 사료업체, 부화업체, 가공업체, 유통업체, 외식업체, 및 기타 관련 산업에서 골고루 발생하며, 손실보전을 위한 정부의 재정지출 증가로도 이어진다. 이번 연구에서는 고병원성 조류인플루엔자(HPAI) 발생이 미치는 경제적 영향을 계측하고 이와 관련하여 현행 질병 방역체계의 개선 방향을 도출하였다. 근래 들어 고병원성 조류인플루엔자의 연중 발생 가능성이 우려되기 때문에 질병예방과 확산방지를 위한 방역체계의 검토에서 개선 방안에 이르기까지 포괄적으로 다루었다.
