본 연구는 역사적 제도주의의 경로진화 모형을 통해 중국 의료위생정책의 진화경로를 확인해 보는 것에 목적이 있다. 분석 결과 의료위생 정책 변동 패턴은 가겹, 가겹, 표류, 전환이 뒤섞인 역동적 과정을 통해 진화해왔다. 의료서비스 공급부족에 따른 문제를 해결하기 위해 각종 조치들이 추가되는 과정과 시장화에 따른 규제개혁의 조치는 가겹으로 해석된다. 이후 합작의료가 와해되고 자비 의료가 증가되는 표류, 공공성 강화를 위한 각종 조치들이 시행되는 전환의 과정을 거친 것이다. 행위자들의 관점에서 정책변동은 단순한 환경 변화만을 뜻하지 않는다. 이들은 전략적 행동변화를 통해 자신들의 이익을 최대화 하고, 이 과정에서 예기치 못한 정책 표류의 현상이 나타날 수 있음을 확인했다. The object of this study is to examine the progress of evolution in Chinese medical and sanitation service policies through the path evolution model of historical institutionalism. The result of the analysis shows that the variation pattern of medical and sanitation service policy has been evolved with dynamic progress including layering, drift and conversion. Both the process of various measures are added in order to solve the problem derived from deficient medical supply and regulatory reform according to marketization could be interpreted as layering. Policy has been gone through the drift which refers to the increase of medical treatment that patients pays by themselves after cooperative medical treatment and conversion that various kinds of measures were executed to enforce the public nature. From the actors' point of view, fluctuation in policy does not mean only the environmental change. They verified that through the strategic change in behavior, they could maximize their benefits, and also drift of policy could occur in this process.

劉俊榮,張勝成 대구대학교 특수교육재활과학연구소 2006 再活科學硏究 Vol.24 No.2

The hearing impairment happened extensively in the elderly and often resulted in the hearing handicap. A lot of study confused the hearing impairment with the hearing handicap and replaced the score of quality of life by the hearing handicap score to calculate the quality adjusted life years and analyzed the cost-utility of aural rehabilitation. In this study, the confusion of hearing impairment and hearing handicap was clarified, and the relevance between hearing handicap and quality of life was explored in order to examine the fitness of replacing the score of quality of life by the hearing handicap score. The result of this study indicated that the correlation between the hearing handicap and the quality of life. The fitness of correlating model of the hearing handicap and the quality of life was not accepted. So, it was not suggested that replacing the score of quality of life by the hearing handicap score. The inventory of disease-specific quality of life should be developed. Secondly, the poor fitness of correlating model of the hearing handicap and the quality of life could be resulted from the other variables that shall be included in the model. It was proposed to include relevant variables into the model in the future. 청각손상은 노년기에 광범위하게 발생하는 문제이다. 심각한 청각장애를 자주 일으킨다. 많은 연구는 청각손상과 청각장애를 혼돈하는 것 뿐 만아니라 자주 청각장애 검목표의 득점으로 피실험자의 생활 품질을 대표한다. 심지어 청각장애 검목표의 득점으로 생활 품질 조정년을 계산한다. 이것으로 청각 재활의 성공 효과를 분석한다. 본 연구는 청각 손상과 청각장애의 다른 점을 밝히는 것 외에도 주요 목적은 청각장애와 생활 품질의 관련성을 이해하고자 하는 것이다. 이것으로 청각장애 검목표를 생활 품질을 삼는 정당성을 관찰한다. 연구결과에 나타나는 것은 청각 표현과 생활품질의 관련성은 높지 않은 결과를 얻었다. 이 두 가지의 관련 양식은 일반화 하기는 제한점을 갖는다. 그래서 이론적 개념에서 청각 표현과 생활품질은 각자 다른 내용을 갖추고 있다. 자료 통계의 분석 결과도 이 두 가지의 관련 양식에 대해서 유의한 결과를 얻지 못했다. 그래서 청각표현 능력으로 피실험자의 생활 품질을 대신할 수 없다. 마땅히 청각 손상자에게 맞는 적합한 생활 품질 설문지를 발행해야한다. 그 다음에 두 가지의 관련 양식의 관련도 적다. 아마도 청각 손상자의 청각 표현과 생활 품질 간에는 많은 변인의 영향이 존재하기 때문이다. 미래의 연구는 더 많은 상관 관련 인소를 귀납해서 이 이론구조를 검증해야한다는 것을 건의한다.

Evaluation of the susceptibility of coal to spontaneous combustion by a TG profile subtraction method

Yulong Zhang,Sheng Xue,Junfeng Wang,Yue Wu,Zhengfeng Li,Liping Chang 한국화학공학회 2016 Korean Journal of Chemical Engineering Vol.33 No.3

−It is imperative to have an in-depth understanding of the intrinsic reaction between coal and oxygen during low-temperature oxidation, as the reaction is the main source responsible for the self-heating and spontaneous combustion of coal. As low-temperature oxidation of coal involves a series of physical and chemical process and many parallel reactions, it is difficult to directly investigate the intrinsic reaction between coal and oxygen by conventional analytical method. Thermogravimetric analysis (TGA) was used to investigate the intrinsic reaction between coal and oxygen based on the mass change. By means of the subtraction analysis method of TGA, the TG-subtraction curves were obtained by subtracting the TG-N2 curves from the TG-air curves. The results indicate that a TG-subtraction curve can better reflect the intrinsic reaction of coal oxidation than a TG-air curve by eliminating the influence of evaporation of water and thermal decomposition of inherent oxygen-containing groups. In terms of the rate of mass increase, the intrinsic reactions can be divided into three stages: slow oxidation stage, advanced oxidation stage and rapid oxidation stage. The activation energy at each of the stages, obtained by Coats and Redfern’s model, can be used to as a technical parameter to evaluate the proneness of coal spontaneous combustion. The optimum experiment conditions were also developed to study low-temperature coal oxidation with the subtraction method of TGA.

Two-Dimensional ZnO Nanowalls for Gas Sensor and Photoelectrochemical Applications

Sheng-Po Chang,Chen-Hua Wen,Shoou-Jinn Chang 대한금속·재료학회 2014 ELECTRONIC MATERIALS LETTERS Vol.10 No.4

Zinc oxide (ZnO) nanowalls were vertically grown on a glass substrate through a fast, low-temperature, catalystfree process in a tube furnace. The morphology and microstructure of ZnO nanowalls were characterized by field-emission scanning electron microscopy, x-ray diffraction analysis, transmission electron microscopy, and photoluminescence measurements. The ZnO nanowall films showed strong UV emission and preferential c-axis orientation, with a hexagonal structure. Potential applications of the ZnO nanowalls were further investigated through experiments. The sensitivity of ZnO-based carbon monoxide gas sensors increased with increasing temperature and reached a maximum value at 300°C. In photoelectrochemical experiments, direct photoelectrolysis of water to generate hydrogen was performed using the ZnO nanowalls as the working photoelectrode. For an external bias of 1.2 V, the photocurrent densities reached 0.037 A/cm2 under Xe lamp illumination.

The Effect of Technical Innovation on Producer Services Industry Development in China: Evidence from Fujian Province*

Chang Sheng LIAO 한국유통과학회 2022 The Journal of Asian Finance, Economics and Busine Vol.9 No.3

The effect of technological innovation on the high-quality development of the producer services industry depends on whether or not technical innovation efficiency plays a key role. This study looks at the impact of technological innovation and financial technology (fintech) on the development of high-quality producer services in Fujian Province from 2010 to 2019. The efficiency of technological innovation is measured using Data Envelopment Analysis (DEA) and the Malmquist productivity index. The mean overall innovation efficiency score is 0.639, meaning that Fujian accounts for 36.1% of resource utilization inefficiencies and that there are significant differences in technological innovation efficiency between cities. The findings show that high-quality producer services industries benefited from innovation efficiency, but that the influence of technological innovation efficiency is insignificant. This demonstrates that financial innovation has not been able to completely enhance the development level of the producer services industry. This may be due to the unreasonable output structure of technological innovation and the low industrial transformation rate of technological achievements. This study advocates that the R&D fund allocation structure be optimized. That technological innovation can improve the high-quality development of the producer services industry is a consensus within the academic community.

Changes in fermentation pattern and quality of Italian ryegrass (Lolium multiflorum Lam.) silage by wilting and inoculant treatments

Liu, Chang,Zhao, Guo Qiang,Wei, Sheng Nan,Kim, Hak Jin,Li, Yan Fen,Kim, Jong Geun Asian Australasian Association of Animal Productio 2021 Animal Bioscience Vol.34 No.1

Objective: This study was conducted to investigate the effects of wilting and microbial inoculant treatment on the fermentation pattern and quality of Italian ryegrass silage. Methods: Italian ryegrass was harvested at heading stage and ensiled into vinyl bags (20 cm×30 cm) for 60d. Italian ryegrass was ensiled with 4 treatments (NWNA, no-wilting noadditive; NWA, no-wilting with additive; WNA, wilting no-additive; WA, wilting with additive) in 3 replications, wilting time was 5 hours and additives were treated with 106 cfu/g of Lactobacillus plantarum. The silages samples were collected at 1, 2, 3, 5, 10, 20, 30, 45, and 60 days after ensiling and analyzed for the ensiling quality and characteristics of fermentation patterns. Results: Wilting treatment resulted in lower crude protein and in vitro dry matter digestibility and there were no significant differences in acid detergent fiber (ADF), total digestible nutrient (TDN), water-soluble carbohydrate (WSC), ammonia content, and pH (p>0.05). However, wilting treatment resulted in higher ADF and neutral detergent fiber content of Italian ryegrass silage (p<0.05), and the WNA treatment showed the lowest TDN and in vitro dry matter digestibility. The pH of the silage was higher in the wilting group (WNA and WA) and lower in the additive treatment group. Meanwhile, the decrease in pH occurred sharply between the 3-5th day of storage. The ammonia nitrogen content was significantly lower in the additive treatment (p<0.05), and wilting had no effect. As fermentation progressed, the lactic and acetic acid contents were increased and showed the highest content at 30 days of storage. Conclusion: The wilting treatment did not significantly improve the silage fermentation, but the inoculant treatment improved the fermentation patterns and quality of the silage. So, inoculation before ensiling is recommended when preparing high quality of Italian ryegrass silage, and when wilting, it is recommended to combine inoculation for making high quality silage.

System Identification of Structures with Severe Closely Spaced Modes Using Parametric Estimation Algorithms Based on Complex Mode Indicator Function with Singular Value Decomposition

Chang-Sheng Lin 대한토목학회 2020 KSCE JOURNAL OF CIVIL ENGINEERING Vol.24 No.9

The modal-interference phenomenon usually makes difficulty of parametric estimation, especially for some structural systems with severe modal interference caused from close or even repeated modes. The existence of severe modal interference will degrade the effectiveness of system identification, and may lead to the problem of insufficient model order due to the existence of repeated modes. Multiple input/multiple output modal estimation is therefore usually conducted effectively to meet the sufficient number of measurement channels. In this paper, the Complex Mode Indicator Function (CMIF) is introduced to estimate the number of significant modes of a structure with severe modal interference, and then the singular value decomposition (SVD) is employed to parametric estimation of the major modes of a structural system without additionally evaluating enhanced frequency response function. Numerical simulations and experimental validation of a practical rectangular steel plate confirm the effectiveness of the presented method for parametric estimation of systems with severe closely spaced modes under noisy conditions.

Response-only modal identification using random decrement algorithm with time-varying threshold level

Chang-Sheng Lin,Tse-Chuan Tseng 대한기계학회 2014 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.28 No.6

Modal Identification from response data only is studied for structural systems under nonstationary ambient vibration. The topic of thispaper is the estimation of modal parameters from nonstationary ambient vibration data by applying the random decrement algorithm withtime-varying threshold level. In the conventional random decrement algorithm, the threshold level for evaluating randomdec signatures isdefined as the standard deviation value of response data of the reference channel. The distortion of randomdec signatures may be, however,induced by the error involved in noise from the original response data in practice. To improve the accuracy of identification, amodification of the sampling procedure in random decrement algorithm is proposed for modal-parameter identification from the nonstationaryambient response data. The time-varying threshold level is presented for the acquisition of available sample time history to performaveraging analysis, and defined as the temporal root-mean-square function of structural response, which can appropriately describea wide variety of nonstationary behaviors in reality, such as the time-varying amplitude (variance) of a nonstationary process in a seismicrecord. Numerical simulations confirm the validity and robustness of the proposed modal-identification method from nonstationary ambientresponse data under noisy conditions.
