The resolution of the 1993 Uruguay Round and the opening of Korea's construction market in '97 marked the beginning of the globalization of Korea's domestic construction market. Consequently, the process led to changes in contracting procedures, as well as disputes in construction management. With globalization came a rapid realization of reasonable values, which forced the hierarchical vertical relationship between the owners, constructors, and subcontractors into a more equal, horizontal relationship. Once the hierarchical relationship was altered, the late 1990's witnessed a dramatic increase in managerial disagreements, in addition to escalating legal disputes and expenditures. The horizontal relationship was a new concept and brought forth many complexities. Unfortunately, because all of this was new, management of construction disputes was elementary at best. Anticipation of disputes is the key to effective dispute management. This includes thorough reviews of contract documents, document management, construction records, and checklists. Also necessary is the education of owners and contractors with pertinent knowledge concerning dispute management. The following paper focuses on the importance of observing construction disputes in order to facilitate management thereof.

In this paper, we propose a method of cooperative control(T-cell modeling) and selection of group behavior strategy(B-cell modeling) based on immune system in distributed autonomous robotic system(DARS). Immune system is living body's self-protection and self-maintenance system. Thus these features can be applied to decision making of optimal swarm behavior in dynamically changing environment. For the purpose of applying immune system to DARS, a robot is regarded as a B cell, each environmental condition as an antigen, a behavior strategy as an antibody and control parameter as a T-call respectively. The executing process of proposed method is as follows. When the environmental condition changes, a robot selects an appropriate behavior strategy. And its behavior strategy is stimulated and suppressed by other robot using communication. Finally much stimulated strategy is adopted as a swarm behavior strategy. This control scheme is based of clonal selection and idiotopic network hypothesis. And it is used for decision making of optimal swarm strategy. By T-cell modeling, adaptation ability of robot is enhanced in dynamic environments.

This paper describes research about the realization of a diagnosis system for the surgical operation of the acupuncture. The system consists of the Munjin, Bokjin and Makjin software. The Munjin system diagnoses the pain spots or each Kyoungnats of the hands, root and neck. The Bokjin system diagnoses pressure-pain spots of the twelve Kyoungnak at chest and abdomen by following the displayed positions on the monitor in sequentially. The Maekjin system diagnoses radial pulse or inyoung and chongu according to the Inyoung-Chongu comparison in ethod. Compound diagnosis verifies the results which obtained from each diagnosis routine by the interface rule. This developed system contains the database which for the paitents diagnosis and treatment process recoding.

The article presents the recent research development in polymer ferroelectric non-volatile memory. A brief overview is given of the history of ferroelectric memory and device architectures based on inorganic ferroelectric materials. Particular emphasis is made on device elements such as metal/ferroelectric/metal type capacitor, metal-ferroelectric-insulator-semiconductor (MFIS) and ferroelectric field effect transistor (FeFET) with ferroelectric poly(vinylidene fluoride) (PVDF) and its copolymers with trifluoroethylene (TrFE). In addition, various material and process issues for realization of polymer ferroelectric non-volatile memory are discussed, including the control of crystal polymorphs, film thickness, crystallization and crystal orientation and the unconventional patterning techniques.

This paper proposes a novel analysis method for calculating inverter DC bus capacitance and line reactor parameters. In the realization process, DC bus capacitance parameter, and ripple current, life of DC bus capacitor, interaction between DC bus capacitance can be calculated by using Newton-Raphson procedure. The design scheme of DC bus capacitor and line reactor, specific parameters such as capacitance, loss, ripple current, central average temperature, life, ripple current, loss, size, central temperature of the reactor were given. Simulation results show that this scheme can accurately calculate the DC bus capacitance and line reactor parameters. Compared with calculation result of references, cost and volume are half. The indicators meet the demand of practical engineering. It had affirmed precision of the analytical method and verified correctness and feasibility of this method.

We design and fabricate a widely tunable laser diode made of InGaAsP-InP. The diode is monolithically integrated with a wavelength-selective coupled-ring reflector and semiconductor amplifiers. For realization of a compact size device, deeply etched multi-mode interference couplers and square ring resonators composed of total-internal-reflection mirrors are adopted and fabricated using a self-aligned process. It is demonstrated that the laser diode exhibits single mode operation and 16 nm tuning range with side-mode-suppression-ratio exceeding 20 dB.

Deuterium-tritium reaction is the most promising one in term of the highest nuclear fusion cross-section for the reactor. So it is one of urgent issues to develop materials and components that are simultaneously resistant to high heat flux and high energy neutron flux in realization of the fusion energy. 2.45 MeV neutron production was reported in D-D reaction in KSTAR and regarded as beam-target is the dominant process. The feasibility study of KSTAR to wide area neutron source facility is done in term of D-D and D-T reactions from the empirical scaling law from the mixed fast and thermal stored energy and its projection to cases of heating power upgrade and DT reaction is done.

It is inevitable to control the systematic failure to obtain the software safety integrity of embedded software installed in rolling stock. Because it is not possible to assess systematic failure integrity by quantitative methods, SILs are used to group documentation, methods, tools and techniques throughout software development lifecycle which, when used effectively, are considered to provide an appropriate level of confidence in the realization of a system to a stated integrity level. Normally, safety approval process is through generic product, generic application and specification application for. For safety approval on generic application of software based system, it is required to apply the certified software processes from the planning stage for the assigned SIL. As such, we will develop project specific application with high safety integrity within time limit of contractual delivery schedule through software assessment to the modified area with the re-use of certified software module and documentation. At this point, Hyundai Rotem has developed software processes applicable to support SIL 4 based on EN50128 which was assessed and certified by TUV SUD. This paper introduces the Hyundai Rotem's detailed approach and prospective action to achieve software safety integrity level.

Recent developments in underwater image recognition methods have received large attention by the ocean engineering researchers. In this paper, an improved bi-dimensional empirical mode decomposition (BEMD) approach is employed to decompose the given underwater image into intrinsic mode functions (IMFs) and residual. We developed a joint algorithm based on BEMD and Canny operator to extract multi-pixel edge features at multiple scales in IMFs sub-images. So the multiple pixel edge extraction is an advantage of our approach; the other contribution of this method is the realization of the bi-dimensional sifting process, which is realized utilizing regional-based operators to detect local extreme points and constructing radial basis function for curve surface interpolation. The performance of the multi-pixel edge extraction algorithm for processing underwater image is demonstrated in the contrast experiment with both the proposed method and the phase congruency edge detection.
