  • Currently, since the black-white QR (Quick Response) codes have limited storage capacity, color QR codes have been actively being studied. By multiplexing 3 colors, the color QR codes can allow the code capacity to be increased by three times, however, the color multiplexing brings about the possibility of crosstalk and noises in the acquisition process of the final image, incurring the decrease of bit-recognition rate. In order to improve the bit recognition rate, while keeping the storage capacity high, this paper proposes a new type of color QR code which uses the pattern information as well as the color information, and then analyzes how to increase the bit recognition rate. For this aim, the paper presents an efficient system which extracts embedded information from color QR code and then, through practical experiments, it is shown that the proposed color QR codes improves the bit recognition rate and are useful for commercial applications, compared to the conventional color codes.

  • The groundborne vibration from moving train loads in tunnels could cause damages on structures and make people uneasy. With an aim at developing basis for effective screening measures, this paper attempts to study the characteristics of propagation and attenuation of groundborne vibration from moving train loads in tunnels considering the effect of joints. The wave propagation problem is modeled by a commercial code FLAC and the results are compared to those from using a finite-element-based code DIANA. It is shown that the groundborne vibration is affected significantly by the location and direction of joints.

  • Currently, it is the general trend that the party's autonomy principle is applicable in determining the applicable law for the international private law and the international commercial arbitration. The purpose of this article is to make research on the party's autonomy principle for the international commercial arbitral awards. For this purpose ist to analyse regal issue the applicability of the lex mercatoria and the possibility of $d\acute{e}pe\c{c}age$ relating to the party autonomy. In this Article ist dealt with Art. 29 para. 1 of the Korean Arbitration Act in comparison with Art. 28 para. 1 UNCITRAL Model Law and Art. 1051 para. 1 of the German Code of Civil Procedure. The Art. 28 para. 1 UNCITRAL Model Law and Art. 1051 para. 1 of the German Code of Civil Procedure provides equally. "The arbitral tribunal shall decide the dispute in accordence with such 'rules of law' as chosen by the parties as applicable to the substance of the dispute. Any designation of the law or legal system of a given State shall be construed, unless otherwise expressed, as directly referring to the substantive law of that State and not to its conflict of laws rules." The term 'rule of law' used to describe the applicability of the lex mercatoria and the possibility $d\acute{e}pe\c{c}age$. Unlike Art. 28 para. 1 UNCITRAL Model Law and Art. 1051 para.1 of the German Code of Civil Procedure. Act, Art. 29(1) of the Korean Arbitration Act provides that the arbitral tribunal shall decide the dispute in accordence with the 'law' chosen by the parties as applicable to the substance of the dispute. However the majority view in Korea takes the position that the term 'law' should be interpreted broadly so as to encompass 'rules of law' at UNCITRAL Model Law and the German Code of Civil Procedure.

  • This study gives the vertical motion analysis in multi-directional irregular waves using a commercial code(MAXSURF v.16) based on linear strip theory for a training ship. To verify the commercial code prior to the analysis, we guarantees the reliability of this paper's results using the commercial code by comparing with the results(Flokstra, 1974) of same hull and experimental conditions on a Panamax container. The analysis conditions are Beaufort wind scale No. 5($\bar{T}=5.46$, $H_{1/3}=2m$) based on ITTC wave spectrum, encounter angle Head & bow seas($150^{\circ}$) and Froude number Fn=0.257. Finally, we calculates heave RAO, pitch RAO and obtains the result of ship's response spectra for heave and pitch motions. In the motion response spectrum under the multi-directional irregular waves, heave motion reacts slightly high in short-crested waves and pitch motion reacts high in long-crested waves.

  • This paper describes a computational approach to the quantification of primary damage under irradiation and demonstrates the effect of neutron energy spectra on the formation of the displacement cascade. The development of displacement cascades in ${\alpha}-Iron$ has been simulated using the MOLDY code - a molecular dynamics code for simulating radiation damage. The primary knock-on atom energy, key input to the MOLDY code, was determined from the SPECTER code calculation on two neutron spectra. The two neutron spectra include; (i) neutron spectrum in the instrumented irradiation capsule of the high-flux advanced neutron application reactor (HANARO), and (ii) neutron spectrum at the inner surface of the reactor pressure vessel steel for the Younggwang nuclear power plant No.5 (YG 5). Minor differences in the normalized neutron spectra between the two spectra produce similar values of PKA energy, which are 4.7 keV for HANARO and 5.3 keV for YG 5. This similarity implies that primary damage to the components of the commercial nuclear reactors should be well simulated by irradiation in the HANARO. Moreover, the application of the MD calculations corroborates this statement by comparing cascades simulation results.

  • Two MIMAS MaX fuel rods base-irradiated in a commercial PWR have been reinstrumented and irradiated at a test reactor. The fabrication data for two MOX roda are characterized together with base irradiation information. Both Rods were reinstrumented to be fitted with thermocouple to measure centerline temperature of fuel. One rod was equipped with pressure transducer for rod internal pressure whereas the other with cladding elongation detector. The post irradiation examinations for various items were performed to determine fuel and cladding in-pile behavior after base irradiation. By using well characterized fabrication and re-instrumentation data and power history, the fuel performance code, COSMOS, is verified with measured in-pile and PIE information. The COMaS code shows good agreement for the cladding oxidation and creep, and fission gas release when compared with PIE dad a after base irradiaton. Based on the re-instrumention information and power history measured in-pile, the COSMOS predicts re-instrumented in-pile thermal behaviour during power up-ramp and steady operation with acceptable accuracy. The rod internal pressure is also well simulated by COSMOS code. Therfore, with all the other verification by COSMOS code up to now, it can be concluded that COSMOS fuel performance code is applicable for the design and license for MaX fuel rods up to high burnup.

  • The Uniform Commercial Code (UCC) sets the standards of good faith in a commercial transaction for the sale of goods. With every sales contract, there is an implied obligation for both the seller and the buyer to negotiate the contract and perform under the terms of the contract in good faith. The agreement between both parties and the customs in the industry determine how the good faith standard should be applied to a particular transaction. Generally, the meaning of good faith, though always based on honesty, may vary depending on the specific context in which it is used. A person is said to buy in good faith when he or she holds an honest belief in his or her right or title to the property and has no knowledge or reason to know of any defect in the title. In section 1-201 of the UCC good faith is defined generally as "honesty in fact in the conduct or transaction concerned." Article 2 of the UCC says "good faith in the case of a merchant means honesty in fact and the observance of reasonable commercial standards of fair dealing in the trade." The sales contract will generally determine which party is required to perform first. This provision helps to determine if the buyer or the seller is in breach of the agreement due to failing to perform as stated by the contract. Either the seller must deliver the items before the buyer is required to accept and pay or the buyer must pay for the items before the seller has the duty to act in good faith and deliver the items in a reasonable manner. If the contract does not specifically define who is required to perform, industry customs and fair trade may determine what is acceptable for the transaction. Under the UCC, the buyer is required to pay for the goods when they are delivered, unless the contract states otherwise. Therefore, the UCC imposes an obligation of good faith on the performance of every contract or duty under its purview. The law also generally requires good faith of fiduciaries and agents acting on behalf of their principals. This article discusses problems of the principles of good faith under the UCC. Specifically, this paper focuses on the interpretation of UCC sections and analysis of various cases. By comparing, also, UCC and Korean law, the paper proposes some implications of good faith issues for Korean law.

  • It has been over seven years since Maritime Code of the Peoples Republic of China (hereinafter called the Code) came into force on July 1st 1993. During this period it has played a very important roll in governing Chinas ocean shipping. However, owing to the defects of the Code, many problems have arisen in the performance of the Code, among which is the problem related to delay in delivery. Therefore, it is necessary and inevitable to revise the Code. This study is limited to a rough study on the regulations related to delay in delivery in the Code, such as the definition of delay in delivery, the carriers responsibility for delay in delivery, the carriers exemption from responsibility for delay in delivery, the limitation of responsibility, the procedures of claims for delay in delivery and the difference of the Code from the Korea Commercial Law, the Hague Rules, the Hague-Visby Rules and the Hamburg Rules. Furthermore, some defects in the Code are pointed out and suggestions are provided for the revision of the Code.

  • The Unified Modeling Language(UML) became the standard object oriented modeling language approved by Object Management Group(OMG). However, C++ codes which are generated by some CASE tools supporting UML do not reflect the correct semantics of one-to-many relationship and aggregation relationship. Additionally, since the commercial CASE tools support too many programming languages on one UML class diagram, they do not support efficiently the characteristics of C++ language. Our C++ code generator supports one-to-many relationship, aggregation relationship, code patterns and design patterns. In this paper, we describe design and implementation of the efficient C++ code generator based on UML class diagram.
