According to the revised law of survey, all the geographic information data including 1/1,000 digital topographic maps have to be converted to world geodetic reference system by the end of 2009. National Geographic Information Institute (NGII) formulated the policy to promote the conversion from local geodetic reference system to world geodetic reference system. However, the current conversion rate is lower than planned due to some impeding factors. Therefore, in this paper, those impeding factors are investigated and then efficient conversion strategies are established and provided. The research involves the validation of affine transformation, the determination of critical value for outlier detection and optimal number of common control points for coordinate conversion, and the treatment of old and new control points.

Old train carriages have been used to create artificial reefs (AR) as part of programs to enhance ocean fisheries and recreational resources. This study conducted hydraulic modeling experiments to estimate the structural stability of a train carriage AR. By applying fixed- and movable-bed conditions and Froude similitude, theoretical and hydraulic experiments revealed major design forces(e.g., water waves and currents). The results of this study showed that some dimensionless design parameters (e.g., surf similarity parameters, water particle velocity, scouring, and deposition) also affect the stability of an AR under various wave and current field conditions. In the fixed-bed condition, movement of the AR occurred when dimensionless water particle velocity based on the surf similarity parameter was larger than about 0.32. In the moveable-bed condition, the settlement depth (field values) of the AR ranged from 6 to 30 cm. The results indicated that characteristics of the sediment/bed condition and the direction of external forces acting on an AR should be considered when selecting AR sites.

Noises from the helicopter rotor model are calculated numerically at various pitch angles. The aerodynamic data are calculated by using prescribed wake model and unsteady panel method. The distribution of aerodynamic loads on the blade surface are obtained from $0^{\circ}$ to $9^{\circ}$ pitch angles with equiangular increments of $1.5^{\circ}$. Although thickness noise is not related to the change of pitch angles, loading noise level increases about 3~4dBA every $1.5^{\circ}$ increment of pitch angle. The additive noise level shows sufficient value to perceive the loudness. From the result of directivity pattern the sound level at the lower region of the blade disc plane is higher than that of the upper region.

The purpose of this study is to demonstrate moderating effect of communications on job satisfactions by an emotional intelligence and conflict-relations of employees and to investigate the influence on job satisfactions by an emotional intelligence and conflict-relations of employees in a long-term care facilities. The results were analyzed from the final responses of 379 employees who are working in a long-term care facilities in Gyeong-Gi Province by SPSS 18.0. The method used in this study were factor analysis, t-test, ANOVA, hierarchical regression analysis, moderated regression analysis. The results of this study are as in the following. First, these consequences showed that an emotional intelligence is positively related with job satisfaction among others' emotional appraisal, use of emotion, regulation of emotion and self emotional appraisal. Second, these results are observed that the conflicts of client's protector and superior is negatively related with job satisfaction. Third, these data are convinced that the communications have a partial effects among conflict, relationship and compensation.

Hotel employees' emotional exhaustion, depersonalization, and decreased sense of accomplishment lead to the Hotel Employees' Burnout Phenomenon(HEBP). Specifically, a higher stress level leads to an increased incidence of burnout among employees. This high level of burnout results in a decreased desire to work, and ultimately results in decreased service provision levels. In order to resolve the phenomenon, a healing program linked to psychotherapy may be introduced. This program would serve at the company level. In addition, encouragement and advice from seniors and colleagues are also needed. The psychological burden should be minimized by encouragement and compliments, rather than by the pressure for service quality improvement. Further, the employees' personal will to overcome the problem must be present.

It is possible to study the load characteristics of full-scale hingeless rotor with the changing of physical smallscaled configurations such as rectangular and paddle blades, and metal and composite hubs. In this study, a static test, and a ground and wind-tunnel test were carried out using small-scale rotor models. The static test was carried out to confirm structural stiffness, characteristics of inertia, natural frequency, and damping ratio of rotors, and the ground and wind-tunnel test was carried out to confirm the stability and aerodynamic characteristics under hovering and forward flight conditions. According to the test results, the vertical load in the case of a combination of a small composite hub with paddle blades was higher than that in the case of a metal hub with paddle blades at same condition. Further, it was confirmed that the restraint of the combination of composite hub can be more flexible than the metal hub for the motion of paddle blades.

The purpose of this study was to research the relationships among ethical climate, trust, organizational identification and turnover intention of employees in travel agency. Ethical climates the prevailing perceptions of typical organizational practices and procedures that have ethical content. Ethical climate involves the perceptions of rightness or wrongness present in the organization's work environment, and establishes the norms for acceptable and unacceptable behavior within the company. To accomplish this study, it was determined that the analysis derived from a hypothesis and literature reviews and data collected from 231 employees in travel agency. The results of empirical analysis showed as follows. First, Perceived ethical climate has a significant effect on trust, organizational identification and turnover intention. Second, Organizational identification has a significant effect on turnover intention while trust has no relationship with it. In addition, the mediating role of organizational identification is examined in the relationship between ethical climate and turnover intention. Based on these findings, the implications and limitations of the study were presented including some directions for future studies.

The successful oil storage in the underground cavern is dependent on how to keep the water-tightness around the cavern by the groundwater. If the water-tightness is not secured, gas bubles will leak out and oil migrate to the adjacent empty cavern. An electrical analogy method was employed in studying the influences of the position of horizontal and vertical water curtains, the head of water curtain and the intervals of the cavern spacings and boreholes on the gas leakage and the oil migration into the adjacent empty cavern. The result shows that if the cavern spacing is narrow, the vertical water curtain should be established and if the cavern spacing is more than twice the cavern height, its establishment is not necessary. All the detailed factors required to prevent the oil migration are shown on graphs.
