This paper investigates the tail asymptotic behavior of the severity of ruin (the deficit at ruin) in the renewal model. Under the assumption that the tail probability of the claimsize is dominatedly varying, a uniform asymptotic formula for the tail probability of the deficit at ruin is obtained.

In this paper, we consider a continuous time risk model involving two types of dependent claims, namely main claims and by-claims. The by-claim is induced by the main claim and the occurrence of by-claim may be delayed depending on associated main claim amount. Using Rouch$\acute{e}$'s theorem, we first derive the closed-form solution for the Laplace transform of the survival probability in the dependent risk model from an integro-differential equations system. Then, using the Laplace transform, we derive a defective renewal equation satisfied by the survival probability. For the exponential claim sizes, we present the explicit formula for the survival probability. We also illustrate the influence of the model parameters in the dependent risk model on the survival probability by numerical examples.

The Housing Lease Protection Act was enacted from March 5, 1981 as Law No. 3379 to guarantee the stability of residential life and legal status. After then, there were many problems, but through several times revision, it had improved insufficient part. However, in order to give guarantees actually the position strengthen for homeless poor people many issues still need to be solved and it has been raised. Along the way, with the introduction of the tenant renewal claims, in February 14, 2015, the National Assembly planned to discuss current issues by operating the Special Committee for housing welfare of ordinary people in the extra session. In the current, however, the conflict of the pros and cons is shown clearly. Meanwhile, because the contract renewal claim of tenant was not guaranteed, if the minimum duration of the lease will be lapsed, contract renewal is dependent on the intention of landlord. Thus, the residential stability of homeless poor could become unstable. Therefore, in this paper, to stabilize the residential living for tenants who are in poor status, analyze our term of existence regulation and through the compared to the national legislation about the term of existence, it will try to propose the specific legislative approach to the problem.

As international trade and commerce increases among the nations in the world, it is inevitable fact that disputes rise as well. As these transactions grow more complex, it becomes increasingly important to resolve disputes and conflicts as quickly, efficiently and formatively as possible. In practical commercial affairs, we call a variety of international commercial troubles ‘trade claims’, Trade claims consist of disputes, controversies, or differences which may arise between the parties, out of, or in relation to, or in connection with their contracts, or for the breach thereof. Trade claim should be instituted promptly, otherwise it may be barred by prescription. Also, the other party will not accept the claim by reason of loss of evidence. In this connection, it should be noted that how long the claim prescription would continue. Trade claim should be settled reasonably and amicably between the parties concerned. And if both parties do not reach an agreement through their negotiation, then the claim shall be settled finally by binding arbitration. For the purpose of managing trade claim and arbitration, the trading parties insert in their contracts claim and arbitration clauses. This paper will examine some judicial precedents concerning claim clauses which are closely connected with a time limit of the claim It will also review some famous precedents rendered by the competent courts in connection with the wording, scope and implied renewal of arbitration clauses.
