This experimental study was carried out to examine the heat transfer characteristics of impinging air jet on a flat plate with a set of right angled triangle rods. Each right angled triangle rod in the array was positioned normal to the flow direction and parallel to the flat plate surface. The clearances from a right angled triangle rod to flat plate surface (C=1, 2 and 4 mm) and the distance from nozzle exit to flat plate (H=100 and 500 mm) were changed for the pitch between each right angled triangle rods (P=40 mm). As a result, heat transfer shows best performance at the clearance of C=1 mm, in case clearance changed, and the average heat transfer enhancement rate increased up to 47% compared to the result of a flat plate without a right angled triangle rod.

For the last several decades, it has been recognized that technology is a key factor in becoming an ADC and an advanced firm. So many countries and individual firms have been increasing investments on technology development. Especially LDCs including Korea choose technology transfer and transaction as an important alternative of their own technology development. To activate technology transaction and transfer, it is necessary to establish an technology transaction system, namely a Technomart that will make good connections between technology suppliers and technology buyers, and efficient functional linkages of supporting infrastructures including organizations and laws related with technology transactions. Therefore this study reviewed both the characteristics of technology transfer and transaction and a conceptual structure of a Technomart through a literature review. And then, the study analyzed the Technomart related laws including an intellectual property right, a copyright, a patent right, and electric transaction related laws. In conclusion the study proposed the development directions of the Technomart related laws.

Requirement of facilitating electronic trade transactions and efforts to platform on the electronic trade in major countries are link to the interest of Bill of Lading, the major transportation document, to be electronic, namely interest in Electronic Bill of Lading. Regardless of the benefits from replacing paper based Bill of Lading to the electronic form, which are eliminating of the Crisis of Bill of Lading and cost saving of international trade community, it has not been successful so far. Among the three functions of Bill of Lading, evidence of contracts and receipt of goods can be easily transferable to the electronic form. However the most important function, Document of Title, became the hardest work to replicate in electronic form. The purpose of this paper is to clarify what kind of conditions shall be prepared to ensure the transfer of right and negotiability of the Electronic Bill of Lading and propose to ensure the use of electronic bill of lading and its transfer of right and negotiability in the era of the electronic transactions.

LMP based congestion management method is suggested as an effective tool, because network congestion can be handled by energy price. It is now being widely used in the North American Electricity Markets. Among them, FGR(Flow-gate rights) is considered to be appropriate for our system, as power flow through the congested line is unidirectional and congestion occurs in the known place. In the CBP market, hedging through transmission right is not necessary even though location pricing system is adopted, because there are no risks in the energy price. Rut, transmission rights should be adopted in the advanced market. Key issue when implementing FGR is how to decide transmission right issuance quantify. This paper deals with a method to decide transmission right issuance quantity by using power. Transfer Distribution Factor(PTDF).

An improved finite element-transfer matrix method is applied to the transient analysis of plates with large displacement under various excitations. In the present method, the transfer of state vectors from left to right in a combined finite element-transfer matrix method is changed into the transfer of generally incremental stiffness equations of every section from left to right. Furthermore, in this method, the propagation of round-off errors occurring in recursive multiplications of transfer and point matrices is avoided. The Newmark-${\beta}$ method is employed for time integration and the modified Newton-Raphson method for equilibrium iteration in each time step. An ITNONDL-W program based on this method using the IBM-PC/AT microcomputer is developed. Finally numerical examples are presented to demonstrate the accuracy as well as the potential of the proposed method for dynamic large deflection analysis of plates with random boundaries under various excitations.

The purpose of this study was to analyze the weight transfer patterns under the different golf swing types which are full swing control swing and putting stroke. Two women golfers participated in this study, one(165cm, 94.3kg)being classified as a low-handicap(LH)player, the other(165cm, 54.5kg) being classified as a high-handicap(HH) player. Both players are right-handed. Two force plates(Kistler, 9286AA) were synchronized with a motion capture system(Qualisys ProReflex MCU240). Anteriorposterior, mediolateral, and vertical forces were used as an indicator of the pattern of swing. Four discrete positions which are address, top of backswing impact, and finish were identified as an event and three phases which are backswing downswing, and follow-through between he events were also identified. The results showed that, at impact, the total force was 1.24BW ring the full swing 1.17BW during the control stroke, 1.00BW during the putting stroke. Depending on the golf swing types, the differences are existed. At impact, the distribution of forces is different with a low-handicap(LH) player and a high-handicap(HH) player. A LH player has 26% in right foot and 74% in left foot during the full swing 49% in right foot and 51% in left foot during the control swing 49% in right foot and 51% in left foot during the putting stroke. A HH, on the other hand, has 74% in right foot and 26% in left foot during the full swing 62% in right foot and 38% in left foot during the control swing 54% in right foot and 46% in left foot during the putting stroke. From address to top of backswing the amount of vertical forces are changed 43:57(right foot: left foot) to 76:24 during the full swing 47:53(right foot: left foot) to 75:25 during the control swing 50:50(right foot: left foot) to 54:46 during the putting stroke. The biggest weight transfer pattern took place in full swing and the control swing is next, and the putting stroke is the final.

This study examines the seller's liability to transfer the property to the buyer. Even though contracting parties choose CISG as the governing law regulating their obligations and rights by means of their contract, CISG does not concern with the effect generated by the transfer of property. Thus, the issues of the property is settled in conformity with the domestic law applicable by virtue of the rules of private international law. By considering the general rules of the transfer of property in goods under SGA and KCC as the lex rei sitae, the difference of requirements to pass the property between them is analyzed and then the reasons why the transfer of property is importantly considered are discussed. In addition, as CISG does not exclude completely the matters concerning the property and provides the provision like Art 41, the seller's liability to deliver goods free from the third party right or claim is examined under Art 41. Lastly, the practical advice is suggested.

Recently, distribution transfer velocity was extremely lowered by high supply rate of vehicle and low road rate. Therefore expansions of transfer network these were subway, road and railway to recover competitive power as a reform measure of physical distribution traffic were become preference previous subject. For reason of that, an expansion of transfer network is meeting competitive power as selected an elevated road in the ground road network that condition of location calm and get out of the existing urban than the underground road to connect oversensitive a large city and expanded small and medium satellite town. In the meantime, while elevated structures construct, they go through the civilian residential section, agriculture land, etc. The consequence is that it raises a vibration, noise, dust, an infringement of the right to a view and an infringement of the right to a sunshine. In this study, we analyzed Quantitatively sunshine quantity with building 3D simulation model of civil structure. Therefore, we present as planning data to reduce a civilian appeal for dispute of the right to sunshine and an economic and time loss between the government and construction company In addition to that, for the standard of the standard plan of usable sunshine quantity program in the practical business, the building of convenient user interface will be the project to be done.

This study has investigated psychological responses to various TV advertisements by using EEG(electroencephalogram). In particular, it was assumed that the brain wave would show different patterns depending upon the style of the advertisement that could be categorized into two such as 'information transfer' type and 'emotional reaction' type. Ten healthy males participated in the experiment. EEG signal was extracted from six lobes such as right and left frontal, right and left occipital, right and left temporal while the subjects were watching TV advertisements. Alpha and beta relative power spectrum, and beta/alpha parameter were calculated to compare two kinds of advertisement each other. Additionally, subjective questionnaire was used to examine subject's response by using adjective words and preference test. In result, significant differences were found in left frontal and right occipital lobe in terms of beta/alpha between two different advertisements. And, subjects showed different preference between two advertisements. It was shown that the current method could analyze the brain reaction to advertisement quantitatively, that presented the possibility of using it to marketing research.

Today's subway system is packed with various informations such as danger/safety signs, directions, and tightly placed advertisements. All these elements are becoming one big chaos rather than convenient source of information for commuters. To solve this problem immediately, it has to be analysed for systematic character of subway spaces and leaded to constructive improvement for the locating subway signs in correct and convenient spots with right contents. Especially in case of transfer stations, structure is complicated and mazed. At the same time, tremendous amount of commuters are passing through and all these commuting are adding more complications and chaos to the system. Therefore, it is harder to focus on gathering environment informations and finding right directions. Better guiding signage for easier transfer is now essential for new standard of modern commuting with total and logical system. Eventually, it will be great help for setting budget efficiency and advanced subway environment through efficient and Koreanized subway transfer system.
