The modern decision environment is characterized by the presence of multiple objectives or goals, which are generally competing or conflicting. Therfore, it has been well established that virtually every decision making problem involves several key criteria. Mathematical programming techniques based on a single objective criterion such as cost minimization or profit maximization are restricted in application to real-world problems. Radford (14) contended that the goal of a global optimum solution should be discarded when considering complex and multiple objective decision problems. Under the modern complex decision environment, it is necessary to simultaneously consider all of the multiple and often conflicting objectives appropriately in selecting a best strategy or policy. Among the various techniques which have been developed to handle multicriteria decision making problems, goal programming is perhaps the most promising approach as it is an appropriate, powerful, flexible, and pragmatic tool. This technique was originally introduced by Charnes and Cooper (2, 3), and further developed by Ijiri (g) and Lee (11). The goal programming model can be solved through the use of a computer program based on an iterative algorithm. Currently, the most widely used computer program is Lee`s program (11) written in Fortran. Another popular algorithm was developed by Ignizio (7). Lee`s and Ignizio`s programs were designed using the modified simplex method. Lee`s and Ignizio`s programs did not consider efficiency in terms of the running time and storage requirements. Computational inefficiency results from unnecessary information being computed from iteration. to iteration. Recently Arthur (1) attempted to design a more efficient algorithm. This algorithm was tested in comparison with Lee`s algorithm in terms of computational time. Arthur`s goal partitioning algorithm is more efficient than the other two algorithms because it reduces the number of computations by modifying the matrix size when the number of subproblems increases and by eliminating unnecessary nonbasic variables. The critical disadvantage of this algorithm is its inability to provide the final optimal simplex tableau required to perform sensitivity analysis. This paper presents a new efficient GP algorithm based on the product represenation of the revised simplex method in order to overcome deficiencies of computational inefficiency on the part of the Lee and Ignizio algorithms and the lack of the final simplex tableau on the part of the Arthur algorithm.

A three-dimensional numerical analysis was carried out on incompressible flows in the refill valve of check valve type containing ball by using commercial code. A numerical simulation is a useful technique to investigate the physical phenomena of the flow field. This study focused on the flow analysis in the tiny gap between valve body and ball in order to prevent pressure drop of refill valve. Characteristics of complex flows including cavitation effect investigated for different gap's size. when length of tiny gap's size become smaller, speed of fluid is rising rapidly and pressure is on the ebb by Bernoulli's theorem. while the pressure fall off below the saturation vapour pressure, we can saw that happening the cavitation phenomenon in this research.

Hwanggumgung (HGG) is a hair-care product which is composed of several plant extracts used in oriental medicine. This study was carried out to investigate effect of HGG on hair regrowth in a shaving model of C57BL6 mice. Five-week-old mice were acclimated for 1 week under 23±3℃, 50±10% relative humidity, and 12h of a light/dark cycle before beginning experiment. There were four experimental groups including distilled water (D.W., control), 10% ethanol (EtOH, vehicle control), a positive control of 3% minoxidil (MXD), and HGG for female and male mice, respectively. Six-weeks old mice were trimmed by electric clippers so as not to damage the skin. The next day, mice without visible scraches were selected, randomized and separated in groups of 11 mice. The test compounds were topically treated with 0.15㎖ per mouse per day for 21 days. The hair regrowth was photographically and histologically determined during the experimental period of 21 days. Enzyme activities of γ-glutamyl transpeptidase and alkaline phosphatase were also determined using a rate assay method. There were no clinical signs in all experimental groups. The topical application of 3% MXD and HGG in female mice promoted hair regrowth earlier and faster than the control groups. In male mice, the topical application of 3% MXD and HGG also accelerated hair growth compared with the controls. Ten percent ethanol also promoted hair growth faster than D.W group. The histology of hair growth in experimental groups was strongly associated with the hair regrowth. 3% MXD and HGG promoted elongation of hair follicles compared with the controls in both female and male mice. Activities of alkaline phosphatase and γ-glutamyl transpeptidase, enzymes related to hair growth, significantly increased after treatments of 3% MXD and HGG for 2 weeks in both female and male mice (p<0.05). These results suggest that HGG has hair growth promoting activities and it can be for treatment for alopecia.
