Through the economic development, people enjoying the camping and demand of camping goods are increasing since they have free time. So they use portable butane gas range outdoor. In addition to that, many restaurants that offer hotpot or meat in Korea use portable butane gas ranges for their convenience. But 19% of gas accidents are using portable butane gas range, 13.7% of them are using oversized cookware. Despite the high accident rate, there is no safety standards about portable butane gas range using oversized cookware. Therefore we conducted to measure temperature and pressure of portable butane gas ranges for reforming safety standards. As a result. we confirmed relation between bottom temperature of the portable butane gas barrel and pressure of the butane gas. Also we confirmed that portable butane gas ranges operate safely when bottom temperature of the portable butane gas barrel is bellow $50^{\circ}C$.

As e-commerce has been activated and internet has been used as usual, higher efficient search engine must be used to promote the value of information and take possession of the market place. all e-commerce user seller and buyer want to competitive goods Although these needs, search results are still much to be desired. In this paper, I will suppose two ideas which are abbreviation result and making blacklist. Abbreviation result is to hide results with common factors and making blacklist is to reduce null links of search results, which makes many useless results. This routine is made of making blacklist, check list, reduce list and append list.

This paper examines the persistence of relative consumer price indices for 15 regions in Korea including 6 metropolitan cities and 9 provinces over the period of 1990-2016. In particular, we ask if relative regional price indices contain a common stochastic trend and find that they are not. We then investigate how quickly these relative prices converge to their long run value and find that a half-life of a deviation from the long run value is in the range of 13 to 22 months for the aggregate consumer price indices and in the range of 7 to 13 months for the tradable goods price indices, which is much quicker than the estimates of previous studies. These estimates suggest that existing monetary models with the realistic duration of price rigidities can generate the persistence in relative price indices.

This study investigates the relationship between size, illumination ,and display of show window. The average width, heigh, and depth of show windows in Taegu area were 341.3, 233.4, and 125.8cm, respectively. As light source, halogen lamp was most frequently used, followed by fluorescent lamp and incandescence lamp. In the actual illumination, however, a combined use of more than 2 light sources was common. Further, a local illumination method, e.g., spot light, was generally adopted. The thought of employers and employees in fashion shops about display and illumination was examined aw well. On the whole, the necessity and importance of display were well recognized but the fact that the illumination should be hamonized with other factors such as color and arrangement of goods was underestimated.

As we know, Incoterms are reflecting only the greatest common measure of practice in int'l trade. Therefore we can think them as the commercial practice most widely used in trade. They contain a number of detail under converse mirror image terms because they connect each other like a thread as to all oversea's commercial transactions between importing buyers and exporting sellers. Therefore they afford convenience to exporters and importers in the world because they tell the parties what to do as to transfer of risk and costs, responsibilities in connection with delivery of the goods. Nonetheless, since Incoterms 1936, they have been periodically revising in order to represent contemporary commercial practice. Therefore, according to change of Int'l trade environment, ICC plans to modify to the 2000 Incoterms. I hope to contribute to revising works by reference of above mentioned revision, that to say, aspects of provision, reflection of prevailing most commonly used, promotion of status as uniform rules, provision of convenience of int'l buyers and sellers. harmony with existing int'l instruments, presentation of criteria in variation of Incoterms.

This paper shows the architecture of IPS(Intermarket Payment System), an implementation of the electronic payment function for internet-shopping merchant system. Because the original purpose of commerce transaction is the exchange of money for goods or services, it is very important to prepare an exchangeable economic value or method. The electronic payment system is the hardware or software or both to process an electronic payment transaction. It has two type, the broker type and the electronic value type. The broker type means an intermediator between real bank network and internet commerce transaction. The electronic value type means a substitute for money in the real world. This paper shows the architecture and the function to implement the broker type electronic payment system. The system has two parts. One is the mediator part to support multiple payment systems and to offer common access methods for merchant system database. The other is the executor part to implement the payment protocol and to process payment transaction.

Simulation modeling has become an extremely important approach to analyzing complex system. In recent years the number of people using simulation as problem-solving aid has increased. In this Paper, we developed a simulation model for analyzing the physical distribution system in ports. we used Arena 2.2 which is a kind of simulation software based common simulation language, SIMAN V. And then, we applied this model to kwangyang port(partially) and analyzed the effect of it upon port system in according to change of the quantity of goods transported.

Normally, suppliers have to decide on what, how much, and when to replenish stocks of goods based on a data flow generated by a vendor managed inventory(VMI) system. But information from supply chain is often misleading. It is common for such data to be distorted by a lack of coordination and synchronization across several business entities managing different supply chain operations. This phenomenon is called the 'bullwhip effect(BwE)'. Many researchers, working over many years, have studied the reasons for the BwE. They have proposed various remedies, but this phenomenon persists. Though overlooked in previous research, this paper reveals that the 'lot size' of a supply chain of distribution is indeed the main cause of the BwE. In addition, some problems in the existing methods of measuring the BwE are identified and a revised much improved method of measurement is suggested.

Common belief in border regions holds that Mexican cross-border shoppers play a larger role in the regional economic base than they do and that NAFTA will provide a bigger stimulus to the regional economy than it is likely. In the regional economy than it is likely. In the first case, price elasticities are implicitly underestimated as highly inelastic and in the latter case, overestimated as highly elastic. This paper provides empirical evidence on the effects of distance and real exchange rates as price proxies on both field survey and population-imputed estimates of cross-border shopping. After estimating both distance-based and real exchange rate-based estimates of price elasticities of Mexican shopper demand for U.S. border-region goods, implications are obtained concerning the relative importance for U.S. border-regon economies of more distant Mexican markets, and the likely impacts of NAFTA.

We proposed electronic catalog document structure which can process information of goods configurationally and electronic catalog standard format to support various catalog document format and structure. using XML. We designed and implemented electronic catalog system that can use by user who takes part in the transaction the electronic catalog document defined in electronic commerce integration style. This system was advantageous in getting useful information as it was having a common electronic catalog document for all business transactions using interoperability of the Web Services.
