생물서식지 보호나 산림보호 등을 목적으로 한 국제환경협약들은 향후 국내 가용 토지공급계획에 차질을 줄 수 있다. 즉, 토지공급의 제약은 지가상승과 직결되고 이는 우리나라 산업전반에 상당한 영향을 미치게 된다. 특히 우리나라가 최근 지가안정의 한 방법으로 택지개발 및 공급정책을 사용하고 있는 현실을 감안할 때 경제에 미치는 파급효과가 클 수 있다. 따라서 본논문의 목적은 국내 가용토지공급계획에 제약을 줄 수 있는 국제환경협약들을 살펴보고 예상되는 시나리오하에서 국민총생산 등 국내경제에 미칠 파급효과를 구체적으로 계량화하는데 촛점을 맞추고 있다. 이를 위해서는 토지공급과 토지가격, 그리고 각 거시변수들간의 연관관계를 동시에 파악할 수 있는 연립방정식 체계의 거시계량모형의 구축이 필요하다. 이러한 모형의 개발도 본논문이 갖는 의미 중에 하나일 것이다.

종축업 등록제 시행으로 종계장은 큰 폰 증가했지만, 과거 허가제였던 종축업에 대한 법적 자율성을 부여하기 위해 등록제로 전환되면서 영세한 농가들의 참여로 전문성이 떨어지고, 질병에 노출되면서 생산성이 하락하는 결과를 낳았다. 총 509 농가 종계장 가운데 등록종계장은 373 개소 (73.3%)와 미등록종계장중 육성전문농장은 25개소 (4.9%), 성계사육농장은 111개소 (21.8%)를 차지하면서 (2010년 2월 기준) 종계시육시설이 노후화되거나 미비한 농가에 대한 정부차원의 관리가 이루어지지 않는 것이 현실이다. 정부는 국내 양계산업 생산성을 높이기 위한 방안으로 종축장의 위생수준과 종축 능력 향상을 위해 지난해 종돈장에 이어 올해 초 종계장을 대상으로 '우수종계장 종합평가사업'을 진행했다. 주최 농림수산식품부, 주관 국립축산과학원, 시행기관은 종축개량협회(종돈)와 대한양계협회(종계)에서 진행한 이번 사업은 우수농장을 꼽아 시설 및 운영자금에 대한 인센티브를 제공해 1차 산업의 전문화와 청정화를 가속화해 종계장간의 자율경쟁을 유도할 뿐만 아니라 종계장 평가를 통해 양계농가에 종계 선택 지표를 제공한다는 계획이다. 지난해 말부터 대한양계협회를 비롯해 국립축산과학원, 국립수의과학검역원, 한국계육협회, 농협중앙회에서는 신청한 농가를 대상으로 평가에 참여한 32개 농가 중 서류심사를 통과한 16개 농가를 대상으로 실사위원이 현지 점검을 통해 지난 3월 19일 총 7개의 우수종계장을 선발했다. 본지를 통해 종계장의 평가기준에 따라 현장 실시를 통해 선정된 총7개소 농장을 소개해 농가 선택지표에 도움을 주고자 소개하고자 한다.

(사)한국포장협회(회장 신동호)는 지난해 9월 1일부터 총 92개 회원사를 대상으로 '회원사 실태조사'를 추진했다. 회원사의 매출규모를 비롯해 재직 인원, 연구개발 및 품질관리 실태, 또 내수 및 대외 수출 활동 현황, 경쟁력 여부 등을 조사 분석한 후 2017년 5월 '2016년도 (사)한국포장협회 회원사 실태조사 결과 보고서'를 발표했다. 이 보고서는 연포장 가공, 필름 및 시트, 알루미늄박, 그라비어잉크, 제판, 인쇄기계 및 부품, 기타 부자재 생산 및 판매를 조사 분석하여 신뢰성 있는 통계자료를 만드는데 초점을 맞춰 실시했다. 협회 관계자는 "조사사업을 통해 협회 회원사가 국내 패키징산업에서 차지하고 있는 비중을 파악하고, 국내 및 외국 바이어들에게 우리협회 회원사의 생산능력과 생산기술 등을 소개하는 자료로 활용할 뿐만 아니라 도출된 통계 자료를 바탕으로 패키징산업에 대한 대정부 지원을 유도하고, 협회가 추진하고 있는 해외수출사업의 지원 자료를 위한 기초 자료를 만들 계획"이라고 소개했다. 또한 "이 보고서는 회원사는 물론 패키징업계가 공유해 과잉투자, 과당경쟁방지에도 활용할 예정"이라고 말했다. (사)한국포장협회는 2년마다 전 협회 회원사를 대상으로 실태조사사업을 실시하고 그 결과를 발표하고 있다. 다음에 '2016년도 (사)한국포장협회 회원사 실태조사 결과보고서'의 주요 내용을 살펴보도록 한다.

This study on condominium complex will adopt the quantitative assessment of the influence on the environment throughout the entire life cycle of buildings. This paper applies input-out analysis in order to analyse embodied energy regarding input of materials at material production phase. Also, it calculates environment load at use and demolition and destruction Phases of buildings as analysing energy consumption. The study categorises environment load as six impact categories and undertakes environmental impact evaluation. The consequence shows that the environment load of multi-unit dwelling takes up 88.2% out of the entire environment load of condominium complex. Also, as a result of analyzing the environmental impact of the life cycle of condominium buildings, it was found that such environmental impact comprised of about 11.96% of all industries in Korea that had an environmental impact.

This study identified and quantified the hidden flows for steel and iron production in Korea using MIPS (Material Input per Service) methodology. In order to estimate the input orientated impact on the environment caused by the manufacture or services of a product, MIPS indicates the quantity of resources used for this product or service. In 2005, 71 million tons of raw materials were used to produce $17.6 million of added value and 4.8 thousand tons of finished steel. The amount of natural resources extracted from natural environments for the purpose of steel production was 245 million tons of TMR(Total Material Requirement), 1524 million tons of water, and 34 million tons of air. The material intensities for steel production by natural inputs (raw materials and energy) was 4.3 ton/ton of TMR, 28 ton/ton of water, and 0.5 ton/ton of air.

We revisit the impact of oil shocks on the Korean economy and examine how this impact varies depending on a business cycle. First, we estimate the probability of a recession through a logistic probability distribution, and correct the probability to match business cycles announced by the Korea National Statistical Office. We set up a STVAR model to analyze the response of macroeconomic variables to oil shocks according to business cycles. We find that oil shocks during the recession have a negative effect on GDP in the mid- and long-term, but during the expansion, GDP does not show a statistically significant response to oil shocks. We presume that this finding is associated with the factors of both the increase in demand for consumption and the increase in current account during the economic boom. Also, we find that the impact of oil shocks on the price level was also observed differently in terms of the persistence of inflation by business cycle. These results highlight the importance of an application of a regime switching model, which has been widely used in energy economics in recent years.

Using the inter-industry tables over the period 2010-2013 published by the Bank of Korea, this paper attempts to uncover the national economic role of the marine environmental industries through the estimation of their market size and value-added, and to analyze their economic effects through inter-industry analysis. The results show that the market size of the marine environmental industries has increased from 1.34 trillion won in 2010 to 1.97 trillion won in 2013 and their share in total national output went up from 0.04 % in 2010 to 0.05 % in 2013. Moreover, the value-added of the marine environmental industries, 618.5 billion won in 2010, amounted to 841.5 billion won in 2013 and their proportion in total national value-added has grown from 0.05 % in 2010 to 0.06 % in 2013. Three findings emerge to be used demand-driven model from the inter-industry analysis. First, the production-inducing effect of 1.0 won production or investment in the marine environmental industries has decreased from 1.8845 won in 2010 to 1.8115 won in 2013. Second, the value-added creation effect of that has declined from 0.7680 won in 2010 to 0.7063 in 2013. Third, the employment-inducing effect of 1.0 billion won production or investment in the marine environmental industries has went down from 10.17 people in 2010 to 9.18 people in 2013. In short, the market size and value-added of the marine environmental industries show an increasing trend, but their economic effects reveal a diminishing trend.

To evaluate biological activity of honeydew honey produced by Apis mellifera L. in Korea, we measured antioxidant activity by using DPPH (1,1-diphenyl-2-picryl hydrazyl), ABTS [2,2-azobis(3-ethylbenzothiazoline-6-sulfonate)], FRAP (Ferric reducing antioxidant power), and total polyphenol content assays. Korean honeydew honey respectively scavenged 26% and 86% of DPPH and ABTS radicals at the highest concentration of 10 mg/mL. In the result of FRAP assay, Korean honeydew honey showed activity (126 µM of FRAP value) to reduce Fe³⁺ to Fe²⁺. Total polyphenol content was 73.41 mg GAE/kg. Korean honeydew honey exhibited excellent antioxidant activity due to having high radicals scavenging ability and reducing power of ferric ion as well as the presence of phenolic compounds. These findings suggest that Korean honeydew honey has great potential as a functional food material.

In the biopharmaceutical contract manufacturing organization (CMO) business, establishing a production schedule that satisfies the due date for various customer orders is crucial for competitiveness. In a CMO process, each order consists of multiple batches that can be allocated to multiple production lines in small batch units for parallel production. This study proposes a meta-heuristic algorithm to establish a scheduling plan that minimizes the total delivery delay of orders in a CMO process with identical parallel machine. Inspired by biological evolution, the proposed algorithm generates random data structures similar to chromosomes to solve specific problems and effectively explores various solutions through operations such as crossover and mutation. Based on real-world data provided by a domestic CMO company, computer experiments were conducted to verify that the proposed algorithm produces superior scheduling plans compared to expert algorithms used by the company and commercial optimization packages, within a reasonable computation time.
