We study the impact of loss-aversion and the threat of critical damages from insufficient pollutant abatement, which we jointly call threshold concerns, on the outcome of international environmental agreements. We aim to understand whether concerns for a critical level of damages induce cooperation among countries faced with the well-known free-riding problem, and yield sufficient emission reductions to avoid exceeding the threshold. Specifically, we focus on loss-averse countries negotiating under the threat of either high or low environmental damages. Under symmetry, when countries display identical degrees of threshold concern, we show that such beliefs have a positive effect on reducing the emission levels of both signatories to the treaty and non-signatories, leading to weakly larger coalitions of signatories than in the absence of reference dependence. We then introduce asymmetry, by allowing countries to differ in the degree of concern about the damages. We show that stable coalitions are mostly formed by the countries with higher threshold concerns. When enough countries exhibit standard preferences, the coalition size may diminish, regardless of the degree of concern by the others.

To find out the effect of burn out print finishing for better quality of fabric, examined processing which could make less damages on the fiber because the biggest problem is remained fibers damage after burn out print finishing. Fiber damage examined to the condition of finishing material NaHSO$_4$and H$_2$SO$_4$, 3~10min., 100~13$0^{\circ}C$, glycerin. The fiber damages evaluated the break strength and the surface condition by SEM. Among satin, pile fabric which remained fiber is silk, warp knitted fabric which remained fiber is polyester, the fibers damage level were warp knitted fabric$0^{\circ}C$, glycerin and for 6 minutes by NaHSO$_4$. When carbonized by 20%. 50% and 70% to express textile design, carbonizing rate was not effect on the fiber damage very much. There was almost no damages with glycerine, and almost no damages during 3~6minutes fixation time, 10$0^{\circ}C$ steaming heat fixation by NaHSO$_4$and H$_2$SO$_4$. Without glycerine, there were damage by hydrolysis on polyesters surface and the fiver was broken by fixation time.

This paper presents the approach involving fault detection and diagnosis of gears using pattern recognition and Wavelet transform. It describes result of the comparison between KDI (Kullback Discrimination Information) with the nearest neighbor classification rule as one of pattern recognition methods and Wavelet transform to know a way to detect and diagnosis of gear damages experimentally. To model the damages 1) Normal (no defect), 2) one tooth is worn out, 3) All teeth faces are worn out 4) One tooth is broken. The vibration sensor was attached on the bearing housing. This produced the total time history data that is 20 pieces of each condition. We chose the standard data and measure distance between standard and tested data. In Wavelet transform analysis method, the time series data of magnitude in specified frequency (rotary and mesh frequency) were earned. As a result, the monitoring system using Wavelet transform method and KDI with nearest neighbor classification rule successfully detected and classified the damages from the experimental data.

In this paper a damage imaging technique using pre-stack migration is developed using Lamb (guided) wave propagation in composite structures for imaging multi damages by both numerical simulations and experimental studies. In particular, the paper focuses on the experimental study using a finite number of sensors for future practical applications. A composite laminate with a surface-mounted linear piezoelectric ceramic (PZT) disk array is illustrated as an example. Two types of damages, one straight-crack damage and two simulated circular-shaped delamination damage, have been studied. First, Mindlin plate theory is used to model Lamb waves propagating in laminates. The group velocities of flexural waves in the composite laminate are also derived from dispersion relations and validated by experiments. Then the pre-stack migration technique is performed by using a two-dimensional explicit finite difference algorithm to back-propagate the scattered energy to the damages and damages are imaged together with the excitation-time imaging conditions. Stacking these images together deduces the resulting image of damages. Both simulations and experimental results show that the pre-stack migration method is a promising method for damage identification in composite structures.

As to the sphere of application, Article 78 CISG undoubtedly applies to interest on the purchase price. Furthermore, the provision also applies to "any other sum that is in arrears". This language has been interpreted to encompass expenses that one party had on behalf of the other as well as reimbursements when the purchase price is reduced according to Article 50 CISG. However, it is questionable whether this language also extends to claims for damages. Legal scholars seem to agree that one has a right to interest on damage claims under Article 78 if the amount in question has been liquidated vis-a-vis the other party. Whether this right to interest also applies to unliquidated sums, is controversial, however. In this study, as a result of taking into account the puspose of Article 78, we could find the fact that regardless of whether the exact amount of damages has been specified yet, the breaching party still owes compensation to the other party from the time of the breach and, accordingly, the non-breaching party should be entitled to interest payments on the loss from that time. Consequently, Article 78 applies not only to liquidated but also to unliquidated damages.

In order to account for whether a doctor should indemnify damages resulted from violation of duty of care, the fact that a doctor violated duty of care, that damages were incurred, and the link between violation of duty of care and damages incurred, respectively, should be verified. So even though a doctor violated duty of care to patients, he or she will not bear the responsibility to indemnify damages unless it is not verified. If a doctor's negligence in medical practices is assessed that obviously unfaithful medical practice far exceeds the limit of admission of a patient, it will not go against people's general perception of justice or law and order to constitute a medical malpractice itself as an illegal action that will require liabiliy for damage. However, when the limit of admission is set too low, a patient's benefit and expectation of proper medical treatment can be violated. In contrast, if the limit of admission is set high, it can leave too little room for doctors' discretion for treatments due to a bigger risk of indemnification for damages. Thus, a reasonable balance that can satisfy both benefit and expectation of patients and doctors' right to treatment is needed.

This study attempts to suggest a new approach of the estimation of range and degree of fisheries damages caused by a large scale of reclamation undertaken in coastal area using the central limit theorem(CLT) in statistics. The key result of the study is the introduction of the new concept of critical variation of environmental factor($d_{c}$). The study defines $d_{c}$ as a standard deviation of the sample mean($\bar{X}$) of environmental factor(X), in other words, $\frac{\sigma}{ \sqrt{n}}$. The inner bound of $d_{c}$ could be the area of fisheries damages caused by public coastal undertaking. The study also defines the decreasing rate of fisheries production$\delta_{\varepsilon}$, in other words, degree of fisheries damages, as the rate of change in the distribution of sample mean(($\bar{X}$), caused by the continuous and constant variation of environmental factor. Therefore $\delta_{\varepsilon}$ can be easily calculated by the use of table of the standardized normal distribution.

A number of mode shape-based structure damage identification methods have been verified by numerical simulations or experiments for on-line structure health monitoring (SHM). However, many of them need a baseline mode shape generated by the healthy structure serving as a reference to identify damages. Otherwise these methods can hardly perform well when multiple cracks conditions occur. So it is important to solve the problems above. By aid of the fractal dimension method (FD), Qiao and Wang proposed a generalized fractal dimension (GFD) to detect the delamination damage. As a modification of GFD, Qiao and Cao proposed the approximate waveform capacity dimension (AWCD) technique to simplify the calculation of fractal and overcome the false peak appearing in the high mode shapes. Based on their valued work, this paper combined and applied the AWCD method and curvature mode shape data to detect multiple damages in beam. In the end, the identification properties of the AWCD for multiple damages have been verified by groups of Monte Carlo simulations and experiments.

For the assessment of ultimate longitudinal strengths of damaged hull girders, it is preliminarily necessary to determine the extents and locations of the damages due to severe accidents. This paper deals with the estimation of the damages from collisions and groundings of large-sized vessels where deterministic and probabilistic approaches are investigated. Deterministic damages estimated from MARPOL(or ICLL), ABS and DNV are compared with probabilistic damages from IMO guideline and some references including damage statistic data. Damages from MARPOL show largest one among all the investigated damage estimation, since it was developed not for the residual strength of hull girder but for the damage stability calculation. IMO guideline with high level probability of damage(eg. 95% probability level) also forecasts even severer damage extents than MARPOL. On the other hand, assuming average probability level of damage, the calculated damage sizes are around the one from deterministic approaches.
