본 연구는 보호동기이론, 기술수용모델, 계획된 행동이론에 기반하여 사회적 특성요인(지각된 심각성, 지각된 취약성), 기술적 특성요인(지각된 유용성, 지각된 이용용이성), 개인적 특성요인(태도, 주관적 규범, 지각된 행동통제)이 비대면 식품구매서비스 이용의도에 미치는 개별적 영향과 상대적 영향을 밝히고, 이에 대해 한국과 중국 소비자 간에 어떠한 차이가 있는지를 살펴보았다. 이를 위해 비대면 식품구매서비스 이용경험이 있는 한국 서울과 중국 베이징에 거주하고 있는 소비자를 대상으로 온라인 설문조사를 진행하였으며, 총 618명(한국 300명, 중국 318명)으로부터 수집된 자료를 바탕으로 SPSS 26.0프로그램을 이용하여 기술통계분석, 신뢰도 및 타당도 분석, t-test, 다중회귀분석, Chow-Test 등을 실시하였다. 본 연구를 통해 도출된 결과는 다음과 같다. 첫째, 한국과 중국 소비자 모두 팬데믹 상황으로 인해 비대면 식품구매서비스를 더 많이 이용하게 되었고, 한국 소비자보다 중국 소비자들의 비대면 식품구매서비스 이용 증가의 비중이 더 높았다. 둘째, 한국과 중국 소비자의 비대면 식품구매서비스 이용 관련 요인의 수준은 모든 변수에서 보통 수준보다 높게 나타났고, 한국과 중국 소비자 간에 통계적으로 유의한 차이가 있었다. 셋째, 양국 소비자에 대한 다중회귀분석을 실시한 결과, 사회적 특성요인, 기술적 특성요인, 개인적 특성요인 모두 개별적으로 비대면 식품구매서비스 이용의도에 유의한 영향을 미치는 것으로 나타났다. 다만, 융합모델에서는 사회적 특성요인의 영향력이 상실되거나 약화되었다. 영향요인들의 개별적 영향력은 한국 소비자의 경우 기술적 특성요인, 개인적 특성요인, 사회적 특성요인의 순으로, 중국 소비자의 경우 개인적 특성요인, 기술적 특성요인, 사회적 특성요인의 순으로 나타났으며, 융합모델에서의 상대적 영향력도 이와 같았다. 구체적으로 한국의 경우 지각된 유용성, 태도, 지각된 이용용이성, 주관적 규범, 지각된 행동통제 순으로 나타났으나 중국의 경우 태도, 주관적 규범, 지각된 유용성, 지각된 취약성, 지각된 행동통제 순으로 나타났다. 또한 Chow-Test 결과, 한국과 중국 소비자 두 집단의 회귀모형은 유의한 차이가 있었으며, 이 차이는 사회적 특성요인과 기술적 특성요인에서 나타났다. Based on the Protection Motivation Theory, Technology Acceptance Model, Planned Behavior Theory, this study aims to identify how intentions to use non-face-to-face services are formed in the context of social factors (perceived severity, perceived vulnerability), technical factors (perceived usefulness, perceived ease of use), personal factors (attitude, subjective norm and perceived behavioral control), and to examine whether there were significant differences between Korean and Chinese consumers. To this end, an online survey was conducted on consumers who had used non-face-to-face food purchase services, of whom 300 were from Seoul, Korea, and 318 were from Beijing, China. Using SPSS 26.0 program, descriptive statistical analyses, t-test, multiple regression analysis, and Chow-Test were performed. Major research findings are as follows. First, it showed that both Korean and Chinese consumers used non-face-to-face services more frequently because of the outbreak of COVID-19, while the proportion of the increase in the use for Chinese consumers was higher than that of Korean consumers. Second, the level of social, technical, and personal factors and intention to use non-face-to-face services was higher than the average level, and there was a statistically significant difference between Korean and Chinese consumers. Third, it was found that social, technical, and personal factors significantly influenced the intention to use non-face-to-face food purchase services individually. However, in the convergence model, the influence of social factors was lost or weakened. The effects were in the order of technical, personal, and social factors for Korean consumers and personal, technical, and social factors for Chinese consumers. Specifically, for Korean consumers, it was influential in the order of perceived usefulness, attitude, perceived ease of use, subjective norm, and perceived behavioral control. Meanwhile, for Chinese consumers, their influence was in the order of attitude, subjective norm, perceived usefulness, perceived vulnerability, and perceived behavioral control. Furthermore, it was confirmed that there was a significant difference in the regression models between the two countries, which were mainly rooted in social and technical factors.

Nowadays, with the increasing number of automobiles, there are more and more traffic accidents. Even though with many safety devices installed, careless and inexperienced drivers often fail to take uses of advanced technologies built in the devices. One type of unfortunate and avoidable traffic accidents is when drivers in an emergency situation either forget or have no time to turn on the hazard lamps which play an important role in noticing other drivers to pay their attentions, in the result, a great number of follow-up-accidents happened. We have developed a system that is capable to keep trucking the condition of the automobile, and turn on the hazard lamps automatically when an emergency has occurred. The system is reliable, cheap, and no design changes required for the automobile.

국제 원유 가격이 중국물가에 미치는 영향

위위(Wei, Wei) 한중경제문화학회 2015 한중경제문화연구 Vol.4 No.-

This paper investigates the impact of oil price shock on three domestic price indices such as import price index(IPI), producer price index(PPI) and consumer price index(CPI). According to the results of estimated 5-variable VAR model which utilized monthly data from 2000.1 to 2014.7, international oil price does Granger-cause IPI and PPI, but the lags of oil price do not enter into the equation for CPI. The accumulated impulse response analysis shows that the responses of one standard deviation shock of oil price result in 1.435%, 0.319% and 0.107% increases in import, producer and consumer price index after three years, respectively. The results of variance decomposition indicate that the influence of oil price to producer price index is much bigger than the import and consumer price indices.

The paper investigates the impact of terms of trade shock on real GDP, consumer price index (CPI) and real effective exchange rate. Based on VAR model, this paper analyzes the impact of terms of trade on macroeconomic volatility before and after the exchange rate regime reform in China. Before the second quarter 2005, the impulse response analysis shows that the responses of 1% shock of terms of trade result in 0.147%, 0.472% and 0.061% decrease in real effective exchange rate, real GDP, and consumer price index, respectively. After the exchange rate regime reform, the shock leads to 0.181% increases in real effective exchange rate, and 0.068%, 0.082% decrease in real GDP and consumer price index, respectively. The results of variance decomposition indicate that after the exchange rate regime reform, the influence of terms of trade to real GDP has been declined sharply, but as to consumer price index the influence has been bigger than before the reform.

This is a report of a feasibility study on the reduction of harmful substances such as particulate matters and nitric oxides emitted from diesel engines by using a plasma reforming system that can generate hydrogen-rich gas. In this paper, an exhaust reduction mechanism of the non-thermal plasma reaction was investigated to perform its efficiency and characteristics on producing hydrogen-rich gas. Firstly, we explain briefly the chemistry of hydrocarbon reforming. The experimental system is showed in the second part. Finally, we demonstrate the feasibility of producing hydrogen using non-thermal plasma. The experimental results are focused on the influence of the different operating parameters (air ratio, inlet flow rates, voltage) on the reformer efficiency and the composition of the produced gas.

Nowadays, ionizers are used very popular for producing negative oxygen ions, which is good for human being health. However, most of the ionizers in the present market are using needle-plate structure in which corona discharge occurs. Comparing with corona discharge, surface discharge is much more compact in the configuration and produces less ozone. For the purpose of finding out the best reactor structure, four types of surface dielectric barrier discharge (DBD) reactors were examined to produce negative oxygen ions at the conditions of 4.24 ㎸ and 356 ㎐. Then influence of frequency (50 ㎐ to 400 ㎐) on the performance of this reactor was also examined on keeping operation voltage and waveform in constant. The results indicated that the surface DBD reactor showed better characteristics for generation of negative oxygen ions when frequency was between 100 ㎐ and 200 ㎐.

To generate negative ion, a small dielectric barrier discharge (DBD) plasma reactor was used in this study and operated by high AC voltage. With increasing of voltage, we can get more negative ions. However unfortunately, if the input voltage is too high, it will also cause formation of ozone which is very harmful to human being health. So the work of finding out the best condition of Voltage and frequency was carried out firstly. After several times of measurement, operating at 20 ㎑ frequency is the best condition generating high ion concentration without ozone. For the purpose of finding out the best reactor structure, two types of surface dielectric barrier discharge (DBD) reactors were examined to produce negative oxygen ions at the conditions of 20 ㎑ frequency. The results indicated that the surface DBD reactor with several small tips showed better characteristics for generation of negative oxygen ions at the same condition.
