The objectives of this research are to see if the phenomena of "demand following" and "supply leading" exist in the business cycle, as well as to look at how liquidity and output react to changes in credit risk, investment-saving gap, inflation, exchange rate, and growth rate of real national output. Employing quarterly data of Maluku and North Maluku (2008-2019), this study utilizes VAR/VECM for inferential analysis. This research found three important findings. First, liquidity and output growth influenced each other in the long run. Second, the determinants of output growth for Maluku are liquidity, investment-saving gap, and inflation, while the determinants of liquidity are output-growth, the gap of investment-saving, and inflation. Third, the determinants of output growth for North Maluku are liquidity, credit risk, investment-saving gap, inflation, exchange rate, and the national output-growth, while the determinants of liquidity are output-growth, credit risk, investment-saving gap, inflation, exchange rate, and national output-growth. The findings of this study supported the hypothesis of demand following and supply leading theory in the Maluku and North Maluku business cycles. This study concludes that economic development would improve if supported by liquidity adequacy through increased deposit growth.

This study focuses on the analysis of the results of computational fluid dynamics simulations of mist-chemical vapor deposition for the growth of an epitaxial wafer in power semiconductor technology using artificial intelligence techniques. The conventional approach of predicting the uniformity of the deposited layer using computational fluid dynamics and design of experimental takes considerable time. To overcome this, artificial intelligence method, which is widely used for optimization, automation, and prediction in various fields, was utilized to analyze the computational fluid dynamics simulation results. The computational fluid dynamics simulation results were analyzed using a supervised deep neural network model for regression analysis. The predicted results were evaluated quantitatively using Euclidean distance calculations. And the Bayesian optimization was used to derive the optimal condition, which results obtained through deep neural network training showed a discrepancy of approximately 4% when compared to the results obtained through computational fluid dynamics analysis. resulted in an increase of 146.2% compared to the previous computational fluid dynamics simulation results. These results are expected to have practical applications in various fields.

말잘피 게바다말은 우리나라 동해안의 암반조하대에 우점하는 잘피로, 이 곳 연안생태계에서 중요한 기능을 수행한다. 그러나 심한 파도에 노출된 거친 생육 환경으로 인해 지금까지 게바다말의 생태 자료는 미비한 실정이다. 본 조사에서는 동해남부해역에 서식하는 게바다말의 생태적 특성을 알아보기 위해 2017년 8월부터 2018년 7월까지 게바다말 군락지의 환경과 게바다말의 형태적 특성, 밀도, 생체량과 잎 생산성의 변화를 조사하였다. 수중광량과 수온은 봄과 여름에 증가하고 가을과 겨울에 감소하는 뚜렷한 계절 경향을 보였다. 해수의 영양염 농도는 조사 시기마다 유의한 차이를 보였으나, 뚜렷한 계절 변동은 나타나지 않았다. 게바다말의 형태, 밀도, 생체량과 잎 생산성도 가을에 감소하고 봄에 증가하였다. 게바다말의 육수화서는 2월 이후 나타났고, 5월에 최대 비율(15.8%)을 보인 후 8월 이후 탈락되었다. 게바다말의 개체당 및 단위면적당 평균 잎 생산성은 각각 2.1 mg sht^-1 d^-1과 7.5 g m^-2 d^-1이었다. 게바다말의 생장이 가장 활발한 수온은 13-14℃로 조사되었다. 게바다말의 잎 생산성은 수중광량, 수온, 영양염 농도와 유의한 상관관계가 나타나지 않았다. 이는 이 지역이 게바다말 생장에 필요한 충분한 빛, 적절한 수온 범위와 영양염 농도를 제공함을 의미한다.

The notion of green growth emerged in 2009. Since then, policy makers and practitioners have largely adopted the term. Although rather intermittently, there have been academic observations on green growth, with the term often being cited as a paradigm and a policy guide for generating new sources of growth. The most important reasons for the surge in green growth today as a new trend and an international agenda item are the rather unsatisfactory results and pitfalls of sustainable development, which has failed at promoting a tangible international environmental principle or a concrete policy framework. Green growth has been proposed as an alternative simultaneously to foster the dynamics of global environmental governance and to reinvigorate the world economy. This study examines to what extent green growth plays a complementary role in existing global environmental governance. Available evidence provides reasonable grounds for arguing that a positive outcome may well be expected from the evolution of green growth architecture and followed by practical policies. It became a global agenda out of a few influential national governments' control. However, decision makers in the leading countries, both developed and developing must be willing to continue implementing what has been discussed and agreed thus far, beyond changes in political leadership and administrations.

The study investigates the impact of inflation rate on economic growth to find the best-fit model for economic growth in Vietnam. The study applied Vector Autoregressive (VAR), cointegration models, and unit root test for the time-series data from 1996 to 2018 to test the inflation impact on the economic growth in the short and long term. The study showed that the two variables are stationary at lag first difference I(1) with 1%, 5% and 10%; trace test indicates two cointegrating equations at the 0.05 level, the INF does not granger cause GDP, the optimal lag I(1) and the variables are closely related as R2 is 72%. It finds that the VAR model's results are the basis to perform economic growth; besides, the inflation rate is positively related to economic growth. The results support the monetary policy. This study identifies issues for Government to consider: have a comprehensive solution among macroeconomic policies, monetary policy, fiscal policy and other policies to control and maintain the inflation and stimulate growth; set a priority goal for sustainable economic growth; not pursue economic growth by maintaining the inflation rate in the long term, but take appropriate measures to stabilize the inflation at the best-fitted VAR forecast model.

In this paper a brief overview of methods to assess the reliability of mechanical systems and structures is presented. A selection of computational procedures, stochastic structural dynamics, stochastic fatigue crack growth and reliability based optimization are discussed. It is shown that reliability based methods may form the basis for a rational decision making.

In plants, nitrogen is the major component for growth and development. Leaf growth is based on the division, elongation and maturation of cells, which are used for making of epidermis, mesophyll, bundle sheath, xylem, phloem and so on. Dynamics of these tissues with respect to nitrogen are required for better understanding. This experiment was conducted to evaluate effect of nitrogen on the elongation of epidermal and guard cell of two rice (Oryza sativa L.) varieties, Seoanbyeo and Dasanbyeo on May 2000 at Chungbuk national university in Cheongju. After transplaning the 20-day-old seedlings into a/5000 pots, the main characteristics related with cell elongation were investigated and evaluated. A maximum. leaf length reached at 7 or 8 days after emerging from the collar, and also the leaf elongation rates were greatly affected by the increase of N application rate. The initial and final cell length were about $17\mu\textrm{m}$ and $130\mu\textrm{m}$, respectively. Cell divisions occurred within 1.0mm from leaf base. With die higher nitrogen application rate of 22 kg-N $10\textrm{a}^{-1}$, cell division per hour was greater 1.5 to 1.9 and 1.2 to 1.3 fold as compared to the N application rate of 0 and 11 kg-N $10\textrm{a}^{-1}$, respectively. Cell enlargement of epidermal and guard cell under higher N application rate (22kg-N $10\textrm{a}^{-1}$) was finished within about 20 (Seoanbyeo) and 15 hours (Dasanbyeo), while it took much time, about 30 hours.
