Small and micro enterprises are an important part of China’s national economy, and the Chinese government attaches great importance to their important role in promoting supply-side structural reform, promoting high-quality development, and building a modern economic system. The difficulty of financing is the main factor restricting the development of small and micro enterprises. Poor debt financing, lack of shareholder support, operational characteristics of small and micro enterprises, deleveraging policies, Sino-US trade frictions, etc., are the main reasons for the financing difficulties of small and micro enterprises. Measures such as standardizing the operation of small and micro enterprises, improving the financial service system, improving the management system, improving the mortgage guarantee ability, and enhancing the risk identification ability can be taken to alleviate the financing difficulties of small and micro enterprises.

The purpose of this study was to develop a recycling system for ozone off-gas. Although the ozone transmission rate of the injector method differs slightly depending on the ozone injection rate, it reaches approximately 99%, which is very high. During the increase in water inflow to the ozone recycling system from 2 L/min to 10 L/min, the average ozone recycling rate was 99.4% at a 1 ppm ozone injection rate, 98.6% at a 2 ppm ozone injection rate, 98.1% at a 3 ppm ozone injection rate. Ozone treatment facility operating costs can be divided into the costs of pure oxygen production, ozone production, and maintenance. The annual operating costs of ozone treatment facilities in Korea are estimated to be approximately 38.9 billion won. The annual savings are estimated to be approximately 5.8 billion won when the ozone transfer rate of the diffuser method, which is mostly employed in domestic water treatment plants, is 85% and 15% of the ozone is recycled.

Communication scientist McLuhan believes that “media is an important symbol to distinguish different social forms. The emergence and application of each new media heralds the arrival of a new era.” The micro-documentary communication in the context of new media takes the realization of information explosion as the guiding direction, and quickly enters the “micro era”. Chinese micro documentary is the product of the new media era, and has gradually developed into an independent new form of image works. In order to better adapt to the film viewing characteristics of Chinese audiences in the context of new media, China’s Micro-documentaries have made corresponding adjustments in the communication form and creation path, forming creative characteristics with Chinese characteristics.

This study was conducted to propose a way to increase the accuracy and precision of β-ray measurement equipment. Statistical processing results of equivalent evaluation data from 2016 to 2021 confirmed that the concentration of micro dust measured by β-ray measurement equipment was higher than that of micro dust sampler. According to quarterly data, it was confirmed that the data from the third quarter (July to September) showed a different trend from other periods, which is assumed to be due to weather conditions. This study indicates that automatic micro-dust measurement equipment evaluation at air pollution measuring stations during the third quarter should be excluded. The evaluation cycle should be changed from once every two years to quarterly. In addition, when the criterion for determining equivalence evaluation falls within the range of the slope and intercept values of the existing trend line, it is necessary to evaluate the R2 value together and reduce the slope from 0.9-1.1 to 0.9-1.0.

The research aims to analyze the firm-specific and macroeconomic factors that affect insurance company’s financial performance. The research explores the variables that influence the financial performance of the United Arab Emirates (UAE)’ insurance companies. The analysis for determining financial performance considers the following variables: the firm’s age, retention ratio, capital adequacy, underwriting risk/loss ratio, financial-leverage, reinsurance dependency, and macro-economic factors such as GDP per capita, inflation rate considered as independent factors. The return-on-asset (ROA) is the key measuring indicator; it is regarded as the dependent variable for financial performance measures. The research focuses on secondary information obtained from insurance companies’ financial statements. The researcher targeted 18 insurance companies listed on the UAE stock exchanges for study purposes. The research examines the overall factors that influence the financial performance of an insurance company. For analysis of data, software package of social sciences (SPSS version 20) is used. The studies used correlation and multiple linear regression analysis to determine financial performance and their effects. The analysis suggests that there are important and constructive relationships between the size, capital adequacy, and reinsurance dependency, while loss ratio, retention ratio, and financial leverage indicate a major negative relationship. And there’s no link between GDP per capita and inflation.

This work was performed to develop a dip injection wet scrubber (DIWS) system with chlorine dioxide as the oxidant. The exhaust pollutants from a lime kiln of paper-mill were introduced to the system. When NaClO3 was used to oxidize NO into NO2, the oxidation was unsatisfactory and the combination of HNO3 or H2SO4 was required for 100% oxidation. ClO2 is recommended to oxidize NO and SO2 effectively. With the combination of 1st stage of DIWS and ClO2, 57.1% of NOx and 98% of SO2 were effectively removed. In the case of 2nd stage of DIWS and ClO2, 93.5% of NOx and 99% of SO2 were removed. The ClO2+DIWS process was superior to the ClO2+Scrubber process in terms of investment, running cost and NOx removal efficiency.

Seeing the existence of MSME needs that have still not been met although this sector is undeniably important in Indonesian economy, changes in community behaviour and the intensity of the use of technology in the community, financial technology (fintech) has a lot of potentials to become a part of the solution of the problem commonly faced by MSMEs. Therefore this research needs to be done to observe the potential of fintech in integrating MSMEs in terms of the application of technology and knowledge from the community related to fintech. By using Technology Acceptance Model, this research tries to understand the determinant factors of the fintech application used by MSME. Based on the research framework and model, path analysis method used in this research. This research uses primary data gathered by the questioner, which was distributed to MSME. From the analysis conducted, we can conclude that the external factors tested in this research could have an effect on the behaviour intention through perceived usefulness in MSME practice of financial technology. Large variation in MSME educational background, busineess age and size would become a challenge in promoting fintech application, therefore this finding suggests that fintech should be promoted by highlighting what benefits can be obtained by using fintech application.

This paper investigates, in a single equation framework, the effect of bank-specific and macroeconomic determinants on micro-, smalland medium-sized loans by commercial banks in Indonesia. This study uses a sample of 790 observations from 79 commercial banks in Indonesia over the years 2006-2015. This study uses two estimation methods for our panel regressions: static and dynamic generalized method of moments (GMM) panel estimator. In static relationships, the literature usually uses the least square methods on fixed effects (FE) or random effects (RE). I found evidence that all banks, bank profitability and size are positively and significantly related to micro-, smalland medium-sized loans, while the coefficients of liquidity are significantly positive in all specifications, except government banks which is significantly negative. The relationship between risk and credit growth is negative for non-government banks. All estimated equations show that the effect of the capital variable on lending banks to MSMEs is not important in government banks and non-government banks. Finally, macroeconomic variables, such as inflation and gross domestic product, clearly affect the lending of the banking sector particularly non-state banks. The findings have several policy implications to Indonesia government, regulatory authority and bank managers in order to improve bank profitability through bank lending.

This research investigates the role of entrepreneurial leadership in micro-enterprise development in the district of Majalengka in West Java, Indonesia. This study applied a qualitative content analysis method to understand the phenomenon of micro-enterprises comprehensively. The data of this research was collected using surveys, interviews, and a group discussion. The findings indicated that technological information adaptation plays a crucial role in the development of micro-enterprise development. Since the group of millennials dominated the leadership, it has provided more creativity by implementing technological information instead of the previous generation that faced difficulties in adopting the technology. This study noted that inadequate technology adaptation makes micro-business gradually lose customers, and the business was threatened to close. Meanwhile, the role of leadership drives the business development, sales have risen, the number of products has been increasingly diverse, and business capital and number of employees have grown. The establishment of an entrepreneur group could facilitate peer-to-peer contact, knowledge transfer, training, and intervention to enhance leadership and business development. This finding pointed out that the leadership will successfully influence business development when supported by several characteristics such as manage the business, capture opportunities, confidence, firmness, personal integrity, communication, and social and technical expertise.

일반적인 고인성․고성능 시멘트 복합재료의 경우 균질한 재료분포를 위하여 기본적으로 굵은 골재를 배재하는 경향이 있다. 그러나, 굵은 골재를 배재한 섬유 복합 시멘트 모르타르의 경우 재료의 탄성계수가 낮으며 단위시멘트량이 높아 경제성과 효율이 낮은 배합이기 때문에 대량으로 신규 구조물에 적용하기 힘들다. 따라서, 본 연구에서는 적절한 수준의 굵은 골재를 혼입하였지만 여전히 휨인성과 휨강도는 확보하고 있는 동시에, 균열 분산성능도 보유하고 있는 고인성 섬유보강 콘크리트에 대한 개발 연구를 수행하였다. 굵은 골재의 혼입량을 실험 변수로 실험 연구를 수행하였고, 결과에 따르면 고인성 모르타르의 기본 배합에 굵은골재를 잔골재의 25%중량비로 추가한 경우에서 가장 좋은 휨인성 그리고 균열분산 특성을 나타내었다. PVA섬유는 균열분산과 연성 증진에 효과적이었고, 강섬유 섬유의 경우 균열분산보다는 강도 증진에 효과적이었다.

최근 산업 활동에 의해 발생하는 CO2에 대한 처리와 산업부산물에 대한 유효처리 및 자원화 방안이 시급히 요구되고 있다. 본 연구는 콘크리트 혼합재료로 활용이 가능한 산업부산물를 대상으로 탄산화 양생에 의한 건설재료로의 적용성 평가를 목적으로 한다. 이러한 목적을 위해 연구용 시멘트(research cement, RC), 고로슬래그 미분말(GGBFS) 및 유동층 보일러 애시(CFBC)를 대상으로 탄산화 양생에 의한 물리·화학적 변화를 비교 검토하였다. 페이스트 내부의 미세조직 변화를 살펴보기 위해 XRD, SEM 분석을 수행하였다. 실험결과 탄산화 양생을 통해 생성된 반응 생성물인 탄산칼슘은 페이스트 내부의 공간을 채우며 밀도가 높은 미세 구조를 형성함을 확인하였다. 또한, CO2 양생시간이 길어짐에 따라 탄산칼슘 결정이 함께 성장하여 밀실한 미세구조를 이루는 것을 확인하였다.

Background : This study was conducted to develop sustainable and safe ginseng cultivation facilities to cope with climate change and to save labor due to the decrease of labor force in rural areas. Methods and Results : In 2017, we designed the wide-shading facility which was unmanned and labor saving to cope with climate warming and decreasing labor force in farming area for stable and sustainable production of ginseng. The developed model is called model Ⅰ(Slope-shading facility, Gyeongsangbuk-do ARES), model Ⅱ (Slope-shading facility, Gyeonggi-do ARES) and Model Ⅲ (Roof-type shading facility, RDA, NIHHS, Department of Herbal Crop Research). The tested varieties were stem-violet variant, and the transplanting was done by using the 2-years-old seedlings on April 3, 2017 and the planting density was 90 plant/1.62㎡. A thermometer, a light meter, and a rain gauge were installed in the center of the facility on April 13, 2017 to measure the micro-weather in the facility. Micro-weather observations were made from April 14 to October 10, measuring temperature, humidity, light intensity, soil moisture content, water leakage, and wind speed. Surveys were carried out on June 20 and September 29, respectively. The maximum temperature in the facility was 2 to 3℃ lower than the outside, but the relative humidity was 2 - 3% higher in the facility than in the outside. Soil moisture did not show a clear trend among the models. The light transmittance was 5 - 10% and it was the highest in model I, where the height of the shading facility was the highest. Rain leakage was 10 - 36%, the most in model Ⅱ. The amount of leaks increased with the amount of precipitation per hour. In all models, ginseng stem and leaf were damaged due to excessive water leakage. On July 10, stem and leaf were grown well only in wide-shading facility where leakage was adequately blocked with double-sided film. The average wind speed was less than 1.6 m/s during the survey period. The maximum wind speed was 8.8 m/s or less, which did not affect the deformation of the wide-shading facility. In all models, there was no difference in growth of aboveground part and root. Conclusion : As a result, in order to grow ginseng continuously and stably using wide-shading facilities, it is considered that the amount of leakage should be minimized by using material that can prevent leakage in cope with rainfall or heavy rain rather than wind-resistance.

When the reinforced concrete structure is in a high salinity environment, chlorine ions penetrate from the surroundings, resulting in corrosion of the reinforcing bars, resulting in low durability. Therefore, studies on the immobilization of chlorine ions are underway, and anion exchange resin, one of them, was used in this study. In this study, chloride ion fixing ability was confirmed by replacing OPC, conventional bead anion exchange resin, and powder anion exchange resin with mortar and then using an electron probe X-ray micro-analyzer. The bead anion exchange resin replaced 3% of the fine aggregate volume and the powder anion exchange resin 5% of the cement volume. The fabricated specimens were cured for 28 days, immersed in NaCl solution for 28 days, and confirmed by electron probe X-ray micro-analyzer.

The compounds extracted by SDE included 27 alcohols, 13 aldehydes, 22 hydrocarbons, 3 esters, 12 ketones, 1 oxide and 1 N-containing compound, on the other hand, using the SPME method, 7 alcohols, 5 aldehydes, 1 ester, 18 hydrocarbons, 7 ketones, and 1 oxide were extracted. The major volatile flavor compounds of Artemisia annua L. isolated by the two methods were caryophyllene oxide, -caryophyllene, camphor, -selinene, -muurolene, 1,8-cineol, (E)-pinocarveol and pinocarvone. β β γ The sesquiterpene named caryophyllene oxide was the most abundant volatile flavor compound with relative contents of 234.16 mg/kg and 195.44 mg/kg obtained by the SDE and SPME methods, respectively. Among the identified volatiles, sabinene, β-pinene, α-terpinene, γ-terpinene, yomogi alcohol, myrtenol, (Z)-nerolidol, p-cymen-8-ol and eugenol were detected by the SDE method only while (E)-anethole and α-cubebene were detected by the SPME method only. This study confirmed that the composition and contents of the volatile flavor compounds vary between different extraction methods. More volatile flavor compounds were identified using the SDE method than the SPME method.

The safety of the future mankind becomes a world issue due to the climate change driven by global warming. It is inevitable to observe everywhere in daily life the impact of climate change. The level of emergency differs between long-term, mid-term, and short-term, which depends on situation. The impact of climate change in daily life is fairly diverse, and therefore multiple research units of different backgrounds often work together on the measuring and forecasting of the impacts. This paper aims to study the potentially useful methods to analyze and forecast the impact on the changes in transport activities of Canadian Inuit. This is part of the research on the climate change’s impact on the Northern Sea Route area. Either natural or man-made change of external environment forces human to adjust their daily life in order to maintain their utility level of life. Individual or individuals’ group react to the external impact, the way of which differ from others. This fact calls a simulation research on the whole set of input-intermediate process-output. Agents representing individuals or certain subpopulation are given a set of rules to react to stimulus and interact with other agents behave in the realm of simulation. This paper provides methodological discussions on how analyzing and forecasting future change in transport activities in response to climate change. The discussion goes around activity-based approaches that are recently popular in urban planning and transportation planning among available simulation approaches. This paper then discusses the implication and future research agenda.

최근 소득 향상에 따른 레져 생활의 증가로 인해 해안가에 펜션, 리조트등 건축물을 많이 짓는 추세이다. 하지만 바닷가에 건물을 짓는다면 염분으로 인해 철근이 부식되어 건물의 내구성이 저하되기 때문에 이를 방지할 수 있는 새로운 콘크리트의 개발이 필요하다. 일반적으로 라텍스를 콘크리트에 혼입하게 되면 염분 및 수분의 침투에 대해 투수 저항성이 증가하고 수분증발 또는 흡수 등에 의한 건조수축 또는 팽창현상으로 인한 체적변화에 대해 안정성을 가지게 된다. 라텍스란 고무나무로부터 얻어지는 천연제품으로 반투명한 우유빛을 띠는 액체상태로서 콜로이드 같은 작은 구형의 유기체 폴리머입자가 물 속에 분산되어 있는 것을 말한다. 본 연구에 사용된 라텍스는 48%의 폴리머와 52%의 물로 구성된 Styrene-Butadiene계열이다. 라텍스는 유연성을 지니고 있고, 콘크리트 내부의 공극을 충진시켜주며 골재 주위에 필름막을 형성하지만 압축에 의한 파괴가 골재주위의 필름막에서 이루어져 라텍스 혼입률이 증가할수록 압축강도는 감소하는 것으로 판단된다. 이에 미세 강섬유를 보강 하면 콘크리트 내부에 국부적인 인장응력을 발생시켜 입자의 분산을 막아주기 때문에 압축강도가 개선된다. 따라서, 본 연구에서는 바닷가, 해안가에 사용이 가능하고 보통강도를 발현할 수 있는 콘크리트를 개발하고자 한다.
