Ju-Hua Wang,Xiu-Heng Xue,Jie Zhou,Cai-Yun Fan,Qian-Qian Xie,Pan Wang 대한기생충학열대의학회 2015 The Korean Journal of Parasitology Vol.53 No.3

Cryptosporidium andersoni ATP-binding cassette (CaABC) is an important membrane protein involved in substrate transport across the membrane. In this research, the nucleotide binding domain (NBD) of CaABC gene was amplified by PCR, and the eukaryotic expression vector of pEGFP-C1-CaNBD was reconstructed. Then, the recombinant plasmid of pEGFP-C1-CaNBD was transformed into the mouse intestinal epithelial cells (IECs) to study the iron transportation function of CaABC. The results indicated that NBD region of CaABC gene can significantly elevate the transport efficiency of Ca<SUP>2+</SUP>, Mg<SUP>2+</SUP>, K<SUP>+</SUP>, and HCO₃<SUP>-</SUP> in IECs (P<0.05). The significance of this study is to find the ATPase inhibitors for NBD region of CaABC gene and to inhibit ATP binding and nutrient transport of CaABC transporter. Thus, C. andersoni will be killed by inhibition of nutrient uptake. This will open up a new way for treatment of cryptosporidiosis.

Perfect Manipulation of Open Stochastic Quantum Systems with Imperfect Detection

Ju-Ju Hu,Qiang Ke,Ying-Hua Ji 제어·로봇·시스템학회 2022 International Journal of Control, Automation, and Vol.20 No.3

Utilizing the homodyne-based feedback control, this paper studies the influence of quantum detection efficiency on the state transfer control of open quantum systems. Under steady state, we give the relations between the feedback control coefficient, detection efficiency and measurement strength. On this basis, we investigate the state transfer under three typical categories of noise: depolarizing channel, amplitude damping channel and phase damping channel in detail. Moreover, we proposed the control strategy which can completely manipulate the stochastic quantum system from an arbitrary initial state to the target eigenstate with fast convergence for the lower or larger detection efficiency in the absence of additional control. We also find that the state transfer of the system can be realized by no-knowledge quantum feedback. Numerical simulation experiments further verify the control scheme can be extended to multi-quantum bit systems.

Body Position Adjustment May Facilitate Capsule Endoscopic Real-Time Examination in Patients with a Large Amount of Food Retention in the Stomach

Ju-Hua Gou,Bing-Qiang Zhang 대한소화기내시경학회 2014 Clinical Endoscopy Vol.47 No.3

A patient with acute obscure gastrointestinal bleeding was found to have a large amount of food retention in the stomach after fasting for>12 hours. We tried to adjust the patient’s body position to facilitate capsule endoscopic examination. The patient laid on the bed on hisright side, which is the position required for a normal procedure, and then his hip was raised while his upper body was lowered graduallyuntil the pylorus appeared at the center of the screen of the real-time monitor. It took 15 minutes of body position adjustment to make thepylorus appear at the center of the monitor and another 5 minutes for the capsule endoscope to enter the duodenum. The lesion was ultimatelyfound at the terminal small intestine.

對中國地方政府環境責任及環境行政失靈原因硏究 -以地方政府利益趨向爲分析中心-

이국화 ( Ju Hua Li ) 대한정치학회 2015 大韓政治學會報 Vol.23 No.4

環境保護是中國政府一貫堅持的基本國策之一,更是地方政府不可推사的責任。진管如此,中國的現實是政府決策不當或行政失靈被認爲是中國環境오染嚴重的最爲直接和最具作用力的因素之一。現實中,相當多的環境問題根源于地方政府長期以來的經濟增長導向。在經濟利益導向之下,在環境決策與行政執行過程中由于有意无意或難以克服的環境不確定性因素造成的各類近視眼式的短期行爲導致了如今的環境行政失靈甚至環境오染惡化。本文通國對地方政府環境行政特征及環境責任困境的原因分析,探討幷展望提高地方政府環境行政效率和環境責任感的可實現途徑。首先探討了中國環境境行政規制的總體情況,其次考察了環境問題的特征以及中國國內外學者對環境行政的理論與硏究,再次從地方政府作爲環境責任的主體如何執行環境政策方面着手,主要對中央政府、地方政府與環境保護部門、地方政府的環境投資等角度進行分析,檢討了中國環境行政責任失靈的原因到底在何處,最后提出有關政策建議。地方政府的環境行政失靈表明,緊緊依고傳統的經濟增長方式已經使中國的經濟面臨着發展的"병頸",而傳統的發展模式向技術進步,結構轉型轉換是時代的需求和黨務之急。由于環境資源的公共性與外部性,更由于地方政府的利益趨向與環境行政責不明確、地方政府跨區域信息不對稱、環境意識尙不간不上經濟發展等原因,地方政府的環境境行政出現失靈,亦卽地方政府在環境治理活動中, 不能有效地通過其制定的各種環境保護政策和法律法規措施來改善地區環境質量和保護地區環境資源,진管需要增加環境投資但環境投資市場也出現了失靈現象。 Local government environmental responsibility is defined as responsibilities of local government and its employees on its role in environmental protections and to bear the adverse consequences in failure to perform corresponding duties appropriately. Environmentalproblems have become an increasing general concern, which reflects the ineffectiveperforming of local government``s duties on environment protection. And in this “governmentfailure”, the local government``s incomplete responsibility is the most fundamental issues. Constrained local government action relatively less in current environmental laws and regulations, laws about local government environment responsibility less, only a few more and principles, specific content about local government environment responsibility. Environmental responsibility of the oversight mechanisms, penalty mechanism to fails to fulfill environmental responsibility. The current environmental protection policies of China did not make specific practical rules, this thesis studies, under the existing environmental legislation, which aspects the local government should further improve. And through analysis the defects of local government environment responsibility in existing environmental laws and policies, proposed specific ideas about consummate local government environment responsibility. The environmental protection responsibilities of illegal or inappropriate behavior responsibility shall be investigated for administrative system. Its purpose lies in the adjustment of government environmental responsibility accountability legal relations, standardize the government environmental responsibility accountability activity, improve the efficiency of government environmental responsibility accountability. This article focuses on government environmental responsibility, such as lack of accountability subject, accountability object unclear, incomplete accountability procedures, accountability, narrow and from consciousness. In view of the problem of government environmental responsibility system of China put forward the corresponding countermeasures of perfecting China``s environmental responsibility system.

全球環境治理的困境與中國的對應策略

이국화 ( Ju-hua Li ) 대한정치학회 2018 大韓政治學會報 Vol.26 No.3

21世紀以來,中國參與了安全、經濟、社會、環境等各個領域的全球治理活動。經過十多年的發展,中國在上述各個領域參與活動的特征都發生了變化。全球環境治理是隨着環境汚染在全球范圍內的加劇而逐步發展起來的。由于環境的公共性與外部性,全球合作的環境治理已毋庸置疑地被認爲是最必要的和有效的應對途徑。本文首先通過分析環境的公共産品特征,明確了全球環境治理是在无政府狀態下各國爲應對全球環境變化與危机而采取的集體行動。各國在環境治理的國際合作上從推卸責任到負責合作的態度轉變過程是自然的過程。中國在全球環境治理領域,已從早期的强調經濟發展的單一標准、差別性國際責任的問題意識轉變爲注重經濟發展與環境保護的二元標准、共同性國際責任的問題意識。然后本文結合對中國參與全球環境治理起到重要影響的最新因素(卽“2030年可持續發展戰略”)分析了中國參與全球環境治理活動的作用與困境,幷對全球環境治理中的"中國方案"的特征進行了檢討。最后闡述了中國作爲大國,在全球環境治理中應該發揮擧足輕重的作用,展望中國與國際社會携手超越全球環境治理的困境,共同加强環境合作達到雙赢效果。 The frequency of global environmental crisis and the deepening of the global environmental cooperation, drives the global environmental governance from scratch, participating countries from a few to several, participating way from passive to active, and also driving the global environmental governance presenting the characteristics such as unconventionality, self-consciousness, unboundedness, contradictoriness and multidimensionality. Because there are cooperation and competition, consensus of global environmental improvement and individual differences, lack of supervision and poor coordination among different countries, so the global environmental governance is in contradictions and dilemmas. In the future global environmental governance system, it is necessary to adhere to the principle of “common but differentiated responsibilities”, to give full play of power mechanism, market mechanism and social mechanism, advocate inclusive concept, and to encourage various participation, so that we can achieve the goals of the global environmental governance. Through process tracing method,the paper analyzes how the environmental objectives become a pillar of‘the 2030 Agenda for Sustainable Development’as equally important as social and economic goals. From the perspective of global governance, the importance of the environment in the global development agenda is increasing. Environmental issues in ‘the 2030 Agenda for Sustainable Development’will be of great importance in global and China’s environmental governance. The global implications for future environmental governance are mainly reflected in: first,the importance of environmental governance will be significantly increased; second,new partnership will strengthen the roles of environmental NGOs and civil society; third, to achieve environmental goals, governance system will increasingly depend on data-driven reviews; fourth, the role of environmental institutions within the UN system will be further strengthened, esp. the UNEP; fifth, environmental along with climate change financing and technology transfer may be further diversified; sixth,climate change and other environmental issues at the global and national levels will be more integrated. Meanwhile,implications on China are: first, it will offer China’s economic transformation and sustainable development a powerful new force; second, China will significantly enhance its public environmental awareness; third, China will play a key role in global governance with a unique focus; fourth, it will require better environmental management system and capacity of China; fifth, China’s future regional cooperation will be greener. However, in the new norms of the economic situation, these environmental goals increase the pressure and responsibility for China’s governance. At the same time,there are also a series of problems and shortcomings in the 2030 Agenda: First, the targets are too many, vague, and difficult to implement. Second, there may be some conflicting targets in the agenda. Third, environmental goals are lack of quantitative standards. Undoubtedly, the environmental objectives in‘the 2030 Agenda for Sustainable Development’are more integrated, comprehensive and systematic than the Millennium Development Goals, demonstrating international community’s collective efforts to address environmental issues. Therefore, we must attach great importance to observe and research.

대암산 용늪의 유출 패턴에 관한 연구

주국화 ( Ju Hua Zhu ),박종관 ( Jong Kwan Park ) 한국지형학회 2011 한국지형학회지 Vol.18 No.4

본 연구는 용늪의 강우에 대한 유출 패턴을 알아보기 위한 것으로 용늪의 수문곡선을 증수부와 감수부로 나누어 지표수의 유출 반응을 파악해 보았다. 그 결과 다음과 같은 사실을 얻어냈다. 강우강도와 증수부 기울기와의 상관관계에 있어 제1증수부보다는 제2, 제3증수부의 기울기가 더 높은 상관관계를 갖고 있는 것으로 나타나 증수부 시작점의 유출량이 양자 간의 관계에 크게 작용하고 있는 것으로 밝혀졌다. 또한 감수부의 유량감소량은 변곡점의 유량 값이 10ℓ/sec 이상일 경우 첨두유량으로부터 변곡점까지의 경과시간과 유량감소량 사이에 높은 상관관계를 지니고 있는 것으로 조사되었다. 관측기간 동안의 용늪의 평균유출률은 0.54, 평균 직접유출률은 0.14로 분석되었다. 또한 선행강우일수가 짧을수록 기저유량은 크게 나타나고 있었으며 기저유량이 클수록 유출률도 크게 나타났다. 용늪에서 1년간 유출된 지표수량은 41만톤이었으며, 월 최고유출량은 총 유출량의 21.5%를 차지한 9월에, 그리고 월 최저유출량은 1.9%를 차지한 3월에 나타났다. 계절별 최고유출량은 총유출량의 37.7%를 차지한 여름에, 계절별 최저유출량은 9.4%인 겨울에 나타났다. The purpose of this study is to clarify the discharge patterns of Yongnup, Daeam-san. Many hydrographs were analyzed by the types of rising and falling stages, and the slope of those stages with the semi-log graph paper was a key point to distinguish the discharge patterns during rainstorms. The correlation between rainfall intensity and slopes of the second or third rising stage was higher than that between slopes of the first rising stage and rainfall intensity. Also, the coefficient of correlation between discharge decrement and the lapsed time from the peak to inflection point of hydrograph, during high water stages, was better than that during low water stages. The annual average discharge rate of Yongnup was 0.54 and the average direct runoff ratio was 0.14. The total discharge amount from Yongnup was about 410,000 tons for a water year, the monthly maximum amount emerged in September and the minimum amount was occurred in March. In summer, 37.7% was a seasonal maximum runoff ratio; on the other hand, 9.4% was a seasonal minimum runoff ratio in winter.

국제환경규제에 대한 중국 경제외교와 대응전략연구

이국화 ( Ju Hua Li ) 대한정치학회 2015 大韓政治學會報 Vol.23 No.2

중국은 지난 30여 년 간 저렴한 노동력과 풍부한 자원이라는 비교우위를 이용해 경 제규모를 키우면서 대량의 외환을 보유하게 되면서 경제 강국으로 자리매김하게 되었다. 하지만 중국은 경제의 고속 발전과 함께 심각한 환경오염과 자연자원의 비합리적 인 개발로 인한 일련의 환경문제에 직면하게 되었다. 중국입장에서, 환경문제는 국가성장에 필요한 경제성장을 지속 가능하게 하기 위한 중요한 구성부분이 되었으며, 중국정부는 환경문제해결의 주요행위자이며, 국제환경협 약과 규범을 국내 환경정책에 수용하고 반영해 나가고 있다. 즉 환경요소를 국가발전 전략의 중요한 부분으로 제정한 중국정부는 처음부터 친환경적 발전을 선호했던 것은 아니었지만, 국제적 및 지구환경의 변화로 인해 점차 중국 국내의 환경정책을 변화시 키게 되고 새롭게 구성해나가고 있는 것이라고 볼 수 있다. 기존의 연구는 중국이 경제발전을 우선시하고 경제적 이익을 최고로 삼고 국가발전 전략을 선택하였기에 환경정책이 유명무실했음에 초점을 맞추어 진행되었다. 본 연구는 중국이 국제무역에서의 환경규제에 대해 어떻게 인식하고 있는지에 대한 의문에서 출발하여, 국제환경규제에 대한 중국의 대응을 분석하였다. 본 연구의 결과 중국은 대외무역에 있어서 “지속 가능한 발전”을 강조하면서도 구체적인 대응책을 망 설이거나 여전히 근시안적인 대안제시도 적지 않다. 하지만 중국의 대외환경정책은 경 제적 현실주의적 행보만을 보이는 것이 아니라 국제환경 협력에 대한 참여도를 높이면서 국제규범을 국내 환경정책에 반영하려고 하고 있다. 왜냐하면, 중국은 무역관련 환경조치에 효과적으로 대응하기 위하여 무역관련 환경조치에 대한 WTO 및 다자간 환경협약상의 규정 및 취지를 전반적으로 이해함과 동시에 자국의 환경 관련 법제를 개선하고 적절한 무역관련 환경조치를 도입해야 할 필요성을 절실히 느끼고 있기 때문이다. 향후 중국의 환경장벽에 대한 정책과 대응은 경제적 실리만을 추구하기 보다 는 세계화라는 큰 틀 속에서 지속 가능한 경제개발이라는 중국의 국가 목표 하에 대외환경정책을 수립할 것으로 보인다. As international community today has become more dependent on the interdependence between countries due to rapid advances in globalization, there has been a growing need to cope with environmental problems and resource depletion cooperatively. Along with the need for international cooperation in dealing with environmental problems, there has arisen a move to tighten controls on environmental pollution mostly in advanced countries. China has achieved a dramatic economic growth and emerged as the second largest economic power in the world through its domestic economic reform in 1978 and foreign open-door policy. Especially, China entered the system of world economy by joining WTO in December, 2001. Even under the U.S. financial crisis of 2008, it continued to grow to become a member country of G2 and the biggest holder of foreign currencies in the world. However, China is now facing a lot of environmental problems due to severe environmental pollution and irrational exploitation of natural resources, along with its rapid economic growth. Especially, as many advanced countries got to regulate environment, China got damaged a lot, struggling to take measures. Conclusively, international trade conditions have significantly improved, but enforced environmental regulations of international community are a big barrier against China``s international trade and economy. International community today applies global standards to every area. Chinese government is expected to make new strategies and policies and reset the targets and identity of the nation within the large frame of global regime and governance of international environmental cooperation.

Lyapunov-based States Transfer for Open System with Superconducting Qubits

Ying-Hua Ji,Ju-Ju Hu,Qiang Ke 제어·로봇·시스템학회 2018 International Journal of Control, Automation, and Vol.16 No.1

We design control fields to realize states transfer for open quantum system by Lyapunov stability theory, and investigate the states transfer of superconducting qubits in Markovian channels with phase relaxation and energy dissipative relaxation. The numerical simulations indicate that arbitrary state (eigenstate, superposition state or mixed state) transfer and maintenance for Markovian system can be realized under Lyapunov control function by an external steady control field of proper amplitude. Moreover, proper increase of proportional coefficients can accelerate the qubits flip and reduce the vibration frequency of control function.
