This paper examines South Korea's past developmental experience and its current strategy and policy initiatives to overcome global and domestic challenges and sustain economic growth in the twenty-first century, the digital and global era, to explain how the country became a high-income economy. The findings of this research highlight the following three factors: First, the most significant factor in rapid industrialization was the adoption of an outward-looking strategy, with the help of a highly skilled workforce and the development of high-tech manufacturing and services sectors, which was supported by the government plans. Second, the high R&D intensity helped South Korea become a global leader in information and communication technologies, which has emerged from a top-down innovation system that promotes close collaboration between government, industry, and the academic community. Third, according to the recently released Global Entrepreneurship Index, South Korea tops the region in entrepreneurship environment. Among the list of criteria, South Korea dominates in the ease of starting a business and enforcing contracts. They all play a significant role in encouraging investment, production, communication, and, eventually, economic growth. Finally, this paper suggests forward-looking developments promoting transformation and diversification into high-tech manufacturing and digital and green technologies.

Objectives: In this study, an analysis was performed on local government adaptation plans for climate change focusing on the health sector. The limitations of past study results have been summarized and new research subjects for preparing for the advanced second period (2018-2022) of the local government adaptation plan for climate change have been suggested. Methods: First, a review of the literature related to vulnerability assessment and adaptation plans was performed. Next, a comparison among the 16 metropolitan governments' vulnerability assessment results and adaptation plans was made. Lastly, a classification of the adaptation policy and budgets to compare with their real budget amounts was performed. Results: The results show that there is a categorizing discrepancy between vulnerability assessment and adaptation policy. In addition, their adaptation budget amounts turned out to be too large in comparison with the actual budget amounts. Conclusion: The first period (2013-2017) local government adaptation plans for climate change had some limitations. This is because there was a rapid driving force for establishing adaptation plans under the green growth strategy in Korea. Now, we are confronting a risk of adaptation to climate change. By expanding this approach, the government would be able to set up a detailed policy to improve the plans during the second period.

Today, various activities to save energy are being conducted around the world. Even in our country, carbon reduction policy is being conducted for low carbon green growth and with this movement, effort to replace energy sources by recognizing the problems on environment pollution and resource exhaustion due to the indiscrete usage of fossil fuel is being made. Therefore, active study on renewable energy is in progress as part of effort to replace the energy supply through fossil fuel and solar ray industry has rapidly developed receiving big strength of renewable energy policies. The conclusion of this study measuring the surface temperature change of single crystal and polycrystalline PV module in green roof system and non-green roof system aspect are as follows. There was approximately $4^{\circ}C$ difference in PV module temperature in green roof system and non-green roof system aspect and this has the characteristic to decrease 0.5% when the temperature rises by $1^{\circ}C$ when the front side of the module is $20^{\circ}C$ higher than the surrounding air temperature following the characteristic of solar cells. It can be concluded that PV efficiency will be come better when it is $4^{\circ}C$ lower. Also, in result of temperature measurement of the module back side, there was $5^{\circ}C$ difference of PV module installed on the PV module back side and green roof system side on the 5th, $3^{\circ}C$ on the 4th, $2^{\circ}C$ on the 5th to show decreasing temperature difference as the air temperature dropped, but is judged that there will be higher temperature difference due to the evapotranspiration latent heat effect of green roof system floor side as the temperature rises. Based on this data, it is intended to be used as basic reference to maximize efficiency by applying green roof system and PV system when building non-green roof system flat roof.

본 연구에서는 농촌진흥청에서 개발한 LED Chamber System을 이용하여 명기시간 동안 광질과 광조사 방법 제어가 단절단엽의 국화 배양소식물체(Dendranthema grandiflorum L., cv. 'Cheonsu')의 생장에 미치는 영향을 검토하였다. 실험은 청색, 적색 및 녹색의 단일광질 또는 청색+적색, 청색+녹색 및 적색+녹색의 혼합광질 조건하에서 이들 광질을 명기 16시간 동안 연속적으로 또는 초당 50회 간격과 분당 20초간격으로 간헐적으로 제어하면서 42일간 수행하였다. 총 일장을 4시간 단축한 분당 20초 간격의 간헐조사는 관행의 형광등 연속조사에 비해 국화의 절간길이 신장에 의한 신초신장을 촉진하였으나, 배양소식물체의 양적생장은 연속광 처리에 의해 유의하게 증가하였다. 한편, 명기동안 녹색광을 초당 50회 간격으로 간헐제어한 경우 연속조사에 비해 건물중이나 엽면적 증대와 같은 양적생장은 억제되었으나 형태적인 면에서의 절간신장은 촉진되었다. 따라서, LED Chamber System을 이용한 광질이나 광조사 방법의 제어는 관행의 형광등 이용 연속조사에 비해 명기시간 단축에 의한 전력소모량 감소 및 기내 배양소식물체의 생장이나 형태제어에 효과적인 배양기술로 이용 가능할 것으로 판단된다.

지속적인 증가추세를 보이는 화석연료 사용은 지구온난화라는 심각한 환경적, 경제적 문제를 발생시키고 있다. 이에 따른 대비책으로 국제사회는 기후협약과 같은 국제 협약을 통한 온실가스 감축 노력을 경주하기 시작했다. 우리나라도 "녹색성장"을 정책의 주요 패러다임으로 하는 온실가스 감축노력의 일환으로 미래 60년 비전인 "저탄소 녹색성장"의 실천적 목표를 제시한 바 있다. 동시에 이를 달성하기 위한 핵심전략으로 온실가스 감축목표 설정의 필요성을 절감하고 2050년까지의 "녹색성장 국가전략"과 이를 이행하기 위한 "녹색성장 5개년계획"에 온실가스 감축목표를 포함한 바 있다. 최근 들어 정부는 녹색성장위원회의 건의를 수용하여 온실가스 저감 시나리오 중 가장 적극적 대안인 시나리오 3, 즉 2020년까지 2005년도 발생량 대비 4%저감을 정부의 온실가스 감축목표로 설정하였다. 본 연구는 이러한 정부의 정책 목표달성을 지원하기 위하여 교통부문 온실가스 배출량 저감을 위한 교통수요관리 방안 전략을 수립하고 동 전략의 시행에 따른 온실가스 감축효과를 측정하였다. 그 결과 고강도 교통수요관리 방안 전략을 시행할 경우 매년 국가 온실가스 저감목표 중 3.1%에 해당하는 7.59백만t$CO_2eq$를 교통부문에서 저감할 수 있을 것으로 분석되었다. 따라서 정책적 필요 정도에 따라 교통수요관리 방안 전략을 수준별, 단계별로 구분 시행할 경우 저탄소 녹색성장이라는 정부정책 목표달성에 기여할 수 있는 효과적 정책도구로 활용될 수 있으리라 기대한다.

This study was conducted to find optimum mixed sowing ratio of green manure crops to reduce the use of chemical fertilizer as well as to increase the crop yield potential which will foster the utilization of green manure crops in the upland field in view of environment friendly agriculture. According to the study, the mixed ratio, 50:50, of hairy vetch and green barley showed highest nitrogen production yield in the soil due to the relatively higher organic nitrogen supply from the hairy vetch plant as well as nitrogen fixation from the air rather than other mixed ratio. In the 50:50 mixed ratio of hairy vetch and green barely total nitrogen amount in the soil showed 17.2kg per 10a, but in the other treatment ratio such as 75:25, 25:75. total nitrogen fixation amount were 16.7, 16.9 respectively. We also conducted the experiment to compare the effect of the mixed sowing treatment of green manure crops on the production of corn cultivated as a succeeding plant of hairy vetch. According to the result, the mixed ratio, 50:50, of hairy vetch and green barley treatment showed highest yield potential of corn as 153kg per 10a in seed weight which is due to the relatively higher organic nitrogen supply from the hairy vetch plant as well as nitrogen fixation from the air rather than other mixed ratio. In the mixed sowing treatment of hairy vetch 100 and barley 0 ratio, the corn production showed 148kg per 10a which is 5kg lower than that of hairy vetch 50 and barley 50 ratio, but showed statistically no difference between those two treatment. Otherwise, different treatments, such as hairy vetch 75 and barley 25, 25 and 75, 0 and 100 showed statistically different each other. Therefore, it was concluded that green manure crops, such as hairy vetch, green barley and rye were very effective crops to increase the soil fertility and gave the positive effect to the crops to give vegetative and propagative growth condition and, in turn, increased the yield potential. We have to make policy to enhance the utility of green manure crops in the upland crops as well as faddy field for the soil fertility and crop yield production which will guarantee prominent quality of environment friendly agriculture products.

To elucidate the mechanisms by which algal food quality affect Daphnia growths, we measured carbon incorporation rates and respiration rates of Daphnia magna with Cryptomonad Rhodomonas minuta, green algae Scenedesmus acutus and cyanobacteria Synechococcus sp. with varying physiological states as food. Carbon assimilation rates were high with R. minuta and S. acutus and low with Synechococcus sp. showing a similar pattern to the growth rate pattern. There was no clear difference among respiration rates of three algal species. Carbon assimilation rates and respiration rates of D. magna appeared to be independent on Molar C:P ratios in algal foods. Carbon growth efficiencies (incorporated carbon per assimilated carbon amount) were lower when D. magna fed with Synechococcus sp. than fed with R. minuta or S. acutus. Analysis of variance results show that carbon assimilation rates which were sum of incorporation and respiration rates and carbon growth efficiencies were only dependant on species affiliation. Overall, our results showed that algal species with varying ${\omega}3$ polyunsaturated fatty acid content led different carbon incorporation rates and overall carbon assimilation rates of D. magna.

The integration of products and services is being expanded in both manufacturing and service companies such as in Apple's iPod & iTunes, Amazon's Kindle, and Hyundai Motor Company's Mozen. This phenomenon has recently accelerated due to multiple factors including market change, lessening of differences in quality of products or services, the paradigm of participation and sharing, and deindustrialization and evolution toward becoming a service economy. The objective of this paper is to investigate and analyze the status and characteristics of integration of products and services in Korean firms and to suggest policy directions promoting this integration. Towards this purpose, income statements from the Korea Listed Companies Association (KLCA) database of companies listed on the Korea Stock Exchange are analyzed regarding the servitization of manufacturing firms as well as the productization of service firms. In addition, this research investigates the Korean Innovation Survey 2011 database for the service sector and 2010 database for the manufacturing sector in order to evaluate R&D activity in each. In the manufacturing sector, the average ratio of service sales (servitization) was low at 0.208, with bias in the level and distribution of ratios associated with the manufacturing sector. 18 out of a total of 23 sectors (78%) have low servitization, showing there's a long way to go for servitization in the Korean manufacturing sector. In the service sector, the average ratio of product sales (productization) was 9.53%, which is relatively high compared to that of the manufacturing sector. However, the distribution of ratios is also biased, as with the manufacturing sector. Based on this analysis, policy directions are proposed in terms of 1) R&D, 2) concept boost, 3) R&D result spread, 4) statistics, 5) infrastructure and 6) green growth.
