하향주의 제조에 이용되는 누룩으로부터 젖산균을 분리하고, 배양학적 특성과 생리적 특성을 검토하였다. 분리된 총 11균주를 이용하여 알코올 10%와 pH 4.0에서 생육이 억제되는 양조학적으로 적합한 5균주의 젖산균을 분리하였고, 16S rRNA의 염기서열을 분석하여 동정한 결과 Lactobacillus plantarum 1균주, Lactobacillus sakei 1균주 및 Lactobacillus curvatus 3균주로 나타났으며 모두 젖산 간균으로 확인되었고, 이들을 각각 L. plantarum L-3, L. sakei L-10 그리고 L. curvantus L-8, 11, 12로 명명하였다. L plantarum L-3이 배양 초기 pH 4.0일 때 0.78%의 산도를 나타내어 나머지 4균주에 비해 약 10배정도 높은 산을 생성하였다. 분리된 5균주는 모두 $30^{\circ}C$에서 가장 산생성능이 우수하였고, L. sakei L-10을 제외한 모든 균주는 $45^{\circ}C$에서 생육이 정지되었으나, L. sakei L-10은 $40^{\circ}C$에서 생육이 저해되었다. 그리고 에탄을 농도가 6%일 때 산의 생성이 급격히 감소되었으며 L. curvatus L-8, 11, 12는 8% 에탄올에서 거의 생육이 이루어지지 않아 에탄올에 대한 내성이 낮았으며, L. plantarum L-3과 L sakei L-10은 10% 에탄올에서 생육이 정지되었다.

Purpose - The purpose of this paper is to analyze the net effect of the green total factor productivity (GTFP) of China's manufacturing industry from the China-Korea Free Trade Area (China-Korea FTA) quantitatively. Design/methodology - Firstly, the Global Malmquist-Luenberger (GML) index based on the SBM directional distance function is used to measure the GTFP of China's manufacturing and analyze the driving force for its growth. Secondly, the regression discontinuity quantitative analysis is used to determine the impact of the China-Korea FTA on China's manufacturing GTFP. Findings - Our main findings can be summarized as follows: the China-Korea FTA has promoted the GTFP of China's manufacturing with an effect evaluation mainly resulting from green technology progress. And there is industry heterogeneity in the policy effect on the manufacturing GTFP due to the China-Korea FTA. Namely, policy promotion from the China-Korea FTA is more effective on the GTFP of equipment manufacturing than it is on those of other industries. Originality/value - First, an evaluation and analysis of the GTFP development of China's manufacturing that employs GML index based on SBM directional distance function. Second, a quantitative estimate of China-Korea FTA's net effect on China's manufacturing industrial GTFP that uses regression discontinuity analysis, which is considered to be the closest method to natural experiments and superior to other causal inference methods. Third, an in-depth discussion of the practical steps that China's manufacturing can take to improve GTFP development and integrate China-Korea FTA construction into economic development.

본 전 세계적으로 연구개발투자는 꾸준히 증가하고 있다. 2010년 기준 우리나라의 연구개발비는 43.8조로 GDP 대비 3.74%에 해당하고, 이는 세계 3위권의 수준이다. 기업에 있어서 연구개발의 중요성이 강조되는 것은 기술 진보나 기술혁신으로 생산성제고 효과가 발생하고 이것은 기업에 있어서는 미래의 수익률 상승과 시장가치 상승으로 이어질 것이기 때문이다. 더 나아가 한 나라에 있어서는 GDP를 증대시키는 역할을 하기 때문에 그 중요성이 높아지고 있다. 이에 본 연구에서는 산업연관분석을 이용하여 기업 내 연구개발투자가 국민경제에 미치는 파급효과들을 다년도에 걸쳐 분석하고자 한다. 분석은 기업 내 연구개발투자를 외생부문으로 다룸으로써 기업 내 연구개발투자를 중심으로 이루어지게 된다. 1995년과 2000년도의 분석결과 생산유발효과, 부가가치유발효과, 취업유발효과가 1995년에 비해 소폭 하락하다가 2000년부터 2009년도 기간에는 시간의 흐름에 따라 증가하는 것을 확인 할 수 있었다. 이는 1997년 외환위기로 인해 기업의 연구개발투자 비중이 작아졌음에 있을 것으로 판단된다. 또한 외환위기는 기업 내 연구개발투자에 의한 산업별 파급효과에도 변화를 야기했는데 이는 외환위기 이후 우리나라의 산업구조적변화를 반영한 것으로 사료된다.

Microalgae, as photosynthetic organisms, possess the ability to produce a diverse array of bioactive compounds. This study focused on the transformant Chlamydomonas reinhardtii dZL and subjected it to cultivation under varying light intensities (60, 120, 180, and 240 µmol/m²/s). Our aim was to assess the impact of light intensity on both microalgal biomass and carotenoid production. The cultivation took place in 80 mL bubble column photobioreactors, specifically the Multi-cultivator. Notably, the culture exposed to 240 µmol/m²/s exhibited the most rapid cell growth, surpassing even the cell concentration achieved at 180 µmol/m²/s by day 8. A detailed analysis of the specific irradiance rate over time unequivocally revealed a sharp decline in growth rates when the rate fell below 2 × 10^-10 µmol/cell/s. Although the culture with 60 µmol/m²/s yielded the highest carotenoid content (1.2% of dry weight), the culture exposed to 240 µmol/m²/s recorded the highest carotenoid concentration at 8.9 mg/L owing to its higher biomass. Our findings reveal the critical importance of maintaining a specific irradiance rate above 2 × 10^-10 µmol/cell/s to enhance biomass and carotenoid productivity. This study lays the groundwork for defining optimal light intensity conditions applicable to mass culture systems, with the objective of augmenting C. reinhardtii biomass and optimizing carotenoid productivity.

Seaports play a vital role in the economic development of countries, especially for countries having long coastlines such as Vietnam Seaport industry in Vietnam has witnessed an impressive development in recent years. The national cargo throughput in the period 2013-2017 achieved a compounded annual growth rate (CAGR) of 11.8%/year, higher than that of the world (5.1%). However, the differences in planning policies and infrastructure systems has led to the differences in port performance efficiency of regional ports. Therefore, it is necessary to have a general and accurate view of the picture of Vietnam's seaport. The objective of this study was to analyze the relative efficiencies of 26 Vietnam container terminals using traditional output-oriented CCR and BCC DEA model. Malmquist P roductivity Index (MP I) was also applied to evaluate changes in container terminals productivity over time.

Abalone aquaculture has developed very rapidly in Korea. Until the mid 1990s it has annually produced about 100 tons. Since then the yield has increased to about 9,000 tons in 2012. The amount accounts for 20% of the global abalone yield. About 86% of produced abalone is consumed domestically and the rest is exported. 100 tons for export seemed as an unattainable goal back in 2003. However, the export rose up to 1,333 tons in 2012. Despite its rapid growth, Korean abalone industry is faced with some problems. The first is the slowdown of yield increase rates. Abalone production increased by 50~60% until the mid 2000. However, the rate continued to drop to below 10%. Reasons behind the slow increase are deteriorating aquaculture grounds and worsening market problems. Constant aquaculture aggravated productivity and overcrowded facilities at a limited space made matters worse. Moreover, abalone export has stalled and so did domestic consumption. In the meantime, rising mortality of young abalone has lowered productivity at abalone breeding places. The mortality rates of abalone remained below 5% in the early 2000s but rose to 30~40% these days. This translates into rising abalone prices. The market problems imply stagnant or shrinking export as well as domestic consumption. The export increase rates took a nosedive from 200 to below 50 between the early 2000s and the late 2000s. Moreover, the increase rates of domestic consumption have become remarkably sluggish. According to, it stood at 50~60% in the mid 2000s but continued to decrease after 2008. These problems, in turn, affected the size of abalone. The usual abalone size for market was 10~12 shells per kg, but recently the size became smaller and smaller to 15~16 shells per kg. The change of size implies shift in consumption patterns: Consumers not only eat live abalone but also they cook soup with it. The size of abalone for uncooked dish is usually very big, like 10~12 shells per kg. In contrast, smaller abalone, such as 20~25 shells per kg, are used for making soup. Increasing use of smaller abalone leads to lower income of abalone aquaculture households. This is partly because that the size determines the price and the price gap between big abalones and smaller ones is extreme in Korea. For the sustainable growth of Korean abalone industry, we need to come up with strategies. First, a reasonable production system needs to be in place, especially for better management of abalone aquaculture grounds. Management of abalone licenses is also necessary because local governments issue relevant licenses as well as supervising abalone grounds. Second, abalone export destination need to be diversified. Japan, the major importer of Korean abalone, takes up a lion's share of export, at 95%. Third, new consumption style of abalone needs to be developed. Abalone used to be consumed as 'raw type' or Sashimi in Korea. This sole type of consumption hampers the growth of abalone market. Moreover, more strategies are needed to encourage and distribute home cooking of abalone rather than eating-out at restaurants. Last but not least, distribution system should be improved for better delivery of live abalone.
