The purpose of this research to improve old age for marriage and the effect the development of the program is to validate. This program of eight to 60 years old elderly couple in 2008 was 8 in the 10 weeks. To verify the effectiveness of the program prior to the inspection of post-verification. According to the results of analysis, old age in conjugal relations, the area between the pre-post meaningful communication efficiency, the couple agreed, and the couple satisfaction, couple came to feel affection, and expression did not show a meaningful difference. The study on the future social welfare and family welfare-related practices and more effective old age, researchers developed a program to improve the couple relationship is important to emphasize is this.

26 bacterial strains capable of growing on Terephthalic acid (TPA) in minimal medium were isolated from soil and wastewater by selective enrichment culture, and among them, one isolate which was the best in the cell growth and TPA degradation was selected and identified as Pseudomonas sp. T-1 by its characteristics. Cell growth almost revealed a stationary phase at 24 hrs after cultivation. Cell growth dramatically increased in a minimal medium containing 0.1% of TPA as a sole carbon source and TPA was not detected any more at 80 hrs after cultivation. Therefore, it is suggested that Pseudomonas sp. T-1 could be effectively used for the biological treatment of wastewater containing TPA.

This study focused on the validity of Imago couple therapy's contents and the effects of application of the Imago couple therapy model. The participated subjects were 38 graduate students and their spouses. The major findings of this study were as follows. First, the types of couple relations that formed and sustained marital relations after growth could be predicted by the early childhood relationships between the subjects when they were children and their parents. Second, the marital conflicts and frustrations could be healed by the 'parent-child dialogue' and 'guided imagery'. Third, Imago couple therapy was effective for couple counseling to improve the areas of marital relationships, especially marital intimacy, marital communication, communication skills for marital conflicts, mutual respect, gender role, sexual satisfaction, time together, and decision-making. Fourth, Couple's Dialogue was a powerful tool for couple and parent-child relationships as well as general counseling practices.

The present paper explains some advancement made by the authors for the compressible flow computation of the Euler equations based on the unstructured grid and vertex- centered finite volume method. Accurate solutions to the unsteady axisymmetric shock wave propagation problems and three-dimensional airplane flows have been obtained by a high-order upwind TVD and FCT schemes. Unstructured grid adaption is made for the unsteady shock wave problems by the dynamic h-refinement/unrefinement procedure and for the three-dimensional steady flows by the Delaunay point-insertion method to generate three-dimensional tetrahedral mesh enrichment. Some physics of the shock wave diffraction phenomena and three-dimensional airplane flow are discussed.

A feruloyl esterase encoding gene (designated fae6), derived from a leachate metagenomic library, was cloned and the nucleotide sequence of the insert DNA determined. Translational analysis revealed that fae6 consists of a 515 amino acid poly-peptide, encoding a 55 kDa pre-protein. The Fae6 primary structure contained the G-E-S-A-G sequence, which corresponds well with a typical catalytic serine sequence motif (G-x-S-x-G). The fae6 gene was successfully over-expressed in E. coli and the recombinant protein was purified to 8.4 fold enrichment with 17% recovery. The $K_M$ data showed Fae6 has a high affinity to methyl sinapate while thermostability data indicated that fae6 was thermolabile with a half life ($T_{1/2}$) < 30 min at $50^{\circ}C$. High affinity for Fae6 against methyl sinapate, methyl ferulate and ethyl ferulate suggest that the enzyme can be useful in hydrolyzing ferulated polysaccharides in a biorefinery process.

The National Health Insurance Corporation has been retrieving from health care providers the payments made to them by insured patients as a result of the health care providers' arbitrary denial of coverage under the National Health Insurance, and has been disbursing such retrieved monies back to the patients, pursuant to Article 57, Sections 1 and 4 of the National Health Insurance Act. However, such practice is an application of the law that lacks legal exactitude. Another problem with such practice is that there is no legal provision under any laws or notices that expressly prohibits arbitrary denial of coverage. A legislative solution, therefore, is called for to address these issues.

We report the distribution of $^{210}$ Pb and various metallic elements (Al, Fe, Mg, Ca, Ti, Mn, Sr, Ba, Zn, V, Cr, Zr, Ni, Cu, and Y) in the sediment cores from six shellfish-farming bays in the South Sea of Korea. The $^{210Pb}$ inventories in Deukryang, Gwangyang, and Goseong Bay cores were comparable to those expected from the known fallout input. However, the $^{210}$ Pb inventories were two times higher in Jinju, Gangjin, and Hansan-Koeje Bay cores, suggesting an important role of other sources such as fluvial inputs. Based on the enrichment factor analyses, non-detrital fractions of all the measured elements were found to be insignificant. The Mn was highly enriched only in the surface sediments of the Jinju and Goseong Bay, which implies that the surface-sediment environment of these bays is efficiently oxidizing Mn remobilized from either pore waters or bottom seawaters. These data set provides the sources of heavy metal in sediment around shellfish farms and the current level of metallic elements for the future monitoring.

Applying a direct formulation for the enrichment of the displacement field an extended finite element (XFEM) scheme for modeling of cohesive crack growth is developed. Only elements cut by the crack is enriched and the scheme fits within the framework of standard FEM code. The scheme is implemented for the 3-node constant strain triangle (CST) and the 6-node linear strain triangle (LST). Modeling of standard concrete test cases such as fracture in the notched three point beam bending test (TPBT) and in the four point shear beam test (FPSB) illustrates the performance. The XFEM results show good agreement with results obtained by applying standard interface elements in FEM and with experimental results. In conjunction with criteria for crack growth local versus nonlocal computation of the crack growth direction is discussed.

A method has been described for the determination of Cu(Ⅱ), Pb(Ⅱ), Ni(Ⅱ), Cd(Ⅱ), Mn(Ⅱ) and Fe(Ⅲ) by flame atomic absorption spectrometry (FAAS) after preconcentration on Amberlite XAD-16 resin, using hexamethyleneammonium-hexamethylenedithiocarbamate (HMA-HMDTC) as a chelating agent, and NH3/NH4Cl buffer solution (pH 9). Influences of various analytical parameters such as pH, concentration of nitric acid, amount of analytes, diverse ions and sample volume were investigated. The relative standard deviation (RSD) and the detection limit (LOD) were found in the range of 0.8-2.9% and 0.006-0.277 ㎍/mL,respectively. Recoveries obtained by the column method were quantitative ( >95%) at optimum conditions.The method was applied to the determination of some metal ions in seawater and wastewater samples. A high preconcentration factor (about 150 for seawater and 75 for wastewater samples) and simplicity are the main advantages of this suggested method.

Work-related musculoskeletal disorders (WMSDs) are recognized as leading causes of significant human suffering, loss of productivity, and economic burdens on our society. WMSDs are associated with work patterns that include fixed or constrained body positions, continual repetition of movements, force concentrated on small parts of the body, cold environment and vibration. Main effort to protect workers from WMSDs should focus on avoiding repetitive patterns of work through engineering controls which may include mechanization, ergonomic design of tools and equipment, and workplace layout. Where elimination of the risk factors is not practical, administrative controls involving job rotation, job enlargement and enrichment, teamwork should be considered.
