The Unites States has been plagued with soaring health care costs and an alarmingly large number of uninsured population. The Patient Protection and Affordable Care Act of 2010 ushered in the most sweeping health care reform in the United States since the introduction of Medicare and Medicaid in 1965 to address these issues. The law's requirement for individuals to purchase health insurance (the so-called "individual mandate"), however, not only caused a political stir but also prompted constitutional challenges. Some questioned whether the federal government, lacking general police power, could require its citizens to buy unwanted insurance based on its enumerated powers under the U.S. Constitution. This paper summarizes the decision of the U.S. Supreme Court on the constitutionality of individual mandate, and explores how the decision relates to Korea's own universal health care.

Owing to a tremendous progress of information technology we have faced a great change of a society. This change has happened to almost all of a society. As a result intangible goods are also included as a major concern in international trade. We may say U.S. is one of the countries transaction of software is the most flourishing. I have tried to classified the cases of software transaction in U.S. into five groups. As a result I have known the UCC had been applied to the almost transaction of standard software. However UCC had not been applied to custom software and data processing. In these days UCITA which is very similar to a previous proposal UCC 2B has been presented. This is a contract law that would apply to computer software, multimedia products, and databases. It has been designed to create a uniform commercial contract law for those products. Now therefore we should make observation of a tendency about transaction of software in U.S. The reason is that we pay attention to the symbol and dormant power of U.S. in international trade.

Whenever a noise problem of a product is concerned, a first step is to identify the energy transmission path whether it is an air-borne or a structure-borne. Depending on the characteristic of the noise path, tools on the noise reduction are different. In this paper. an important aspect of the “mass law” in a noise transmission has been investigated. Since an air-borne has 20 dB/Decade, and a structure-borne 10 dB/Decade of a sound transmission loss due to a mass, an engineer who aims to have a light product design should have an enough knowledge on the mass law, especially, the sensitivity of the weight itself. A honeycomb plate is examined as a sample of a light structure to implement a mass law.

The modern society is changed into mass production, complicated circulation society and mass consuming society because of the development of the fast science technology since the occurrence of the industrial revolution. Also, the human life style is changed into the abundant consumption society because of the appearance of the various products. The society change like the above provide comfortable life to us. but We are facing with danger for the bad food, illegal medicines and bad products. So, To solve the danger like the above, The Product Reliability Law be made. The both The enterprise and consumer need The Product Reliability Law to protect one's own interest. The consumer is claiming to use the product of safety of the resonable price and good quality in modern society, So, 1 studied on countermeasures of domestic enterprise to increase the competitive power of the enterprise according to Product Reliability Law

The basic stance of the Republic of Korea Ministry of Foreign Affairs was 'quiet diplomacy'. However, there had been demands for specific plans for practical protection of Dokdo. In 2011, Prime Minister Kim Hwang Sik mentioned that they are reviewing measures of stationing marines on Dokdo, while on August 10th, 2012, former president Lee Myung Bak visited Dokdo. The visit itself was meaningful as he was the first supreme commander to visit Dokdo. This paper studies on the necessity of naval power on Dokdo to maintain its effective control. The effective control must be done by a national organization in a peaceful and unimpaired method. If so, can stationing naval power, whether directly or indirectly, on Dokdo be considered a violation of 'peaceful' method? A 'peaceful' effective of control meas the right of sovereignty over a territory without other country's protest. In such terms, protecting a territory falls under practicing the right of sovereignty, and therefore does not violate 'peaceful'. In addition, looking at international cases such as Ligitan/Sipadan Case and Pedra Blanca Case, evidences such as 'navy activity', 'flyng ensign', and 'military communication facility installation' was used. In ter case of Yemen-Eritrea dispute over Hanish, methods on effective control over island and sea was also ruled by the installation of military posts and military surveillance activities. Thus, stationing naval power on Dokdo can be a way of maintaining effective control per international law. To station naval poer on Dokdo, Presidential Instruction 24 integrated Defense Guideline Enforcement Ordinance, which is domestic law, must be revised. Reason being, the Enforcement Ordinance states that the navy area of responsibility excluded Ullundo, where Dokdo is under jurisdiction of Ullungdim thus excluding navy control. In addition, considering the diplomatic situation, it is more fut to install navy radar site on Dokdo rather than 'stationing marines'. In other words, enforcing surveillance in the vicinity of Dokdo and installing radar site instead of stationing direct combatants is one way of practicing effective control without stimulating diplomatic disputes.

The high temperature creep properties of the generating plant's high temperature tube, pipe and header and such are very significant in accordance with long-time exposure to the high temperature and pressure environment. Not only this, but as the welding procedure is compulsory for the cohesion of components, the creep properties regarding the local microstructures of steel weldment are very important. In order to understand the creep properties regarding the local microstructures of steel weldment, the SP-Creep test which is easy to get sample from the field component was conducted. The local microstructure of steel weldment, that is, W.M. and B.M.'s microstructures were observed using the SEM. The rupture time of W.M. was longer as 110 % averagely in a same condition, which is the consequence of the difference of the microstructure. Each lethargy coefficient of B.M. and W.M. is evaluated by the relation among the temperature, load and the rupture time from SP-Creep Test. The life estimation equation can be induced by the transformation of Power-law. B.M. and W.M. for each $550\;^{\circ}C$ and $575\;^{\circ}C$, the very similar to normal temperature of the domestic thermal power generation in working, are estimated.

There are many software reliability models that are based on the times of occurrences of errors in the debugging of software. It is shown that it is possible to do likelihood inference for software reliability models based on finite failure model and non-homogeneous Poisson Processes (NHPP). For someone making a decision about when to market software, the conditional failure rate is an important variables. The infinite failure model are used in a wide variety of practical situations. Their use in characterization problems, detection of outlier, linear estimation, study of system reliability, life-testing, survival analysis, data compression and many other fields can be seen from the many study. Statistical process control (SPC) can monitor the forecasting of software failure and thereby contribute significantly to the improvement of software reliability. Control charts are widely used for software process control in the software industry. In this paper, proposed a control mechanism based on NHPP using mean value function of Musa-Okumo and Power law type property.
