This study is on Yoshimasu Todo's thought of medicines. Conclusions are as below. Medicines are poisons. Therefore, they don't have the ability to restore the vital energy. Medicine-processing(法製) can only be done for doubling the toxicity, since the poison itself is the very effect of a medicine. One poison has an ability to treat only one main symptom. If the poison strikes the main symptom right, it doesn't harm the human body. Since warm-heat-cool-cold(溫熱凉寒) of a medicine can't be known by human ability, it can't be used as the standard of judgment when selecting a medicine.

Big accidents of flyings, vessel, subways, gas equipments, buildings and bridge happens frenquently. Therefore many people are suffering harm of property. The destruction cause of macaine components is almost accused by fatigue. This study is test for STS304 specimen using pure and cantilever bending state. Rounded specimen and notched specimen including fracture surface investigation was comparatively experimented, fatigue life according to degree of surface finishing was examined. Fatigue fracture probability of notched canilever specimens were predicted by P-S-N curve, median rank and Weibull distribution. And at the relation with the rotational speed and stress, the fatigue life of the test specimen was higher at high speed than low speed.

The samll-medium sized cities do not have enough infrastructure for the construction work, especially in terms of concrete supply. This research surveyed the capacity of remicon companies in Gunsan related with production and delivery. Their production capacity is bigger than the daily quantity required, however the delivery capacity is not enough to supply the daily quantity required and it is inevitable to use the several remicon using different admixture. It might cause the harm to the structure. This research studied the way to remove the quality risk when using different admixture at the same time.

The present study is aimed at understanding the flow physics associated with a safety valve applied to LNG ship engines. One-dimensional gasdynamic analyses and axisymmetric, compressible Navier-Stokes computations have been carried out to provide a qualitative and quantitative knowledge base for an effective design of the safety valve. Gasdynamic forces and thrust coefficients are obtained regarding a change in chamber pressure and distance between the nozzle exit and valve sheet which are major parameters to offer a variation in the flow feature. The present results show that the control of the passage area between the nozzle exit and valve sheet can attenuate the strength of shockwave generated in front of the valve sheet, which causes harm to stable system operation.

Crop Protection Products (CPPs) are a useful weapon in our fight against the pests, diseases and weeds that harm or destroy our food. To be effective CPPs need to exhibit some persistence. The consequence of this is that residues of the original material or its metabolites may remain on food and thus there is a potential for the intake of such residues. The issue of CPP residues in food is an emotional subject and is rarely debated rationally or supported by scientific facts. Media headlines like “Poison in our food” or “These days enough Pesticides (CPPs) are sprayed onto vegetables to turn you into one” are testimony to the high level of emotion that surrounds the subject of CPP residues in food. Recent surveys of consumers have indicated that more than 80 percent view CPP residues in food as a “serious hazard”. This significantly exceeds concerns over drugs, hormones in meat, nitrates in food, irradiated foods, food additives, or artificial colours.

The complement system is part of the innate immune response and as such defends against invading pathogens, removes immune complexes and damaged self-cells, aids organ regeneration, confers neuroprotection, and engages with the adaptive immune response via T and B cells. Complement activation can either benefit or harm the host organism; thus, the complement system must maintain a balance between activation on foreign or modified self surfaces and inhibition on intact host cells. Complement regulators are essential for maintaining this balance and are classified as soluble regulators, such as factor H, and membrane-bound regulators. Defective complement regulators can damage the host cell and result in the accumulation of immunological debris. Moreover, defective regulators are associated with several autoimmune diseases such as atypical hemolytic uremic syndrome, dense deposit disease, age-related macular degeneration, and systemic lupus erythematosus. Therefore, understanding the molecular mechanisms by which the complement system is regulated is important for the development of novel therapies for complement-associated diseases.

The purpose of this study and report is to provide, to the MND, an independent cost analysis of modernizing software of F-16 fighter fleets to support the use of several weapon system options, including JDAM, AIM-9X and HARM Targeting System etc. The study analyzed each options with software sizing, software cost, enabling hardware cost, flight test cost, system engineering cost, and 3 strategies. And the study proposed and analyzed some alternative strategies: strategy1 is to modernize software only within existing electronic processing capability; strategy2 is a full upgrade of weapons avionics with plug compatible electronics; strategy3 is an approach defined to mirror the USAF Common Configuration Implementation Approach (CCIP). The recommended alternative is strategy2.

This work is described as an fresh effort to study environmental sustainable management in organic products retailing markets. Sustainable management means creating value for business, nature and society. The main point of this thesis is about the concept, the content and the target of environmental sustainable management, and the technical method and basis to achieve it. Also this thesis shows the strategy of sustainable management as well as the realization of sustainable development by carrying out organic agricultural production. The main content of sustainable management is that: - Rationalize the utilization of resource and energy. - Maximize economic benefit. - Minimize harm to humans and the environment. Examines business strategies that have successfully targeted markets, such as advertising, labeling, gaining consumer trust, partnerships, and diversifying operations. These included management skills, and marketing organic and other sustainably grown products to determine strategies for developing new markets for these products. Suggests that consumers are becoming more aware of the importance of environmentally sound methods for growing food, the health benefits of wholesome food, and are willing to pay more for these products.

윤리적 또는 경제적 이유 때문에 임상실험(Clinical Trials)의 연구자들은 실험중간에 새로운 치료방법이나 약이 효과가 있는지 또는 해로운지를 반복해서 검정한다. 하지만 각 검정마다 정해진 유의수준을 반복해서 사용하면 전체 유의수준이 상당히 커지게 된다. 임상실험에서 발생하는 이러한 문제를 해결하기 위하여 많은 집단측정검정법 (Group Sequential Testing Procedure)들이 개발되어 왔다. 본 논문에서는 이러한 집단측정검정법들을 간략하게 비교분석하고자 한다.

'Navigable airspace' means an airspace at and above the minimum safe flight level, including airspace or flight procedures needed for safe takeoff and landing. Airspace may be established as needed and may be abolished, and in some cases may be limited to airspace management. These are absolutely based on risk assessment. Safety is the state in which the risk of harm to persons or of property damage is reduced to, and maintained at or below, an acceptable level through a continuing process of hazard identification and risk management. 'Risk' is the assessed potential for adverse consequences resulting from a hazard and 'Risk assessment' involves consideration of both the frequency and the severity of any adverse consequence. This paper proposed 'risk assessment procedure' for the structural changes of Navigable Airspaces through literature reviews relevant to manuals on airspace management and risk management.
