  • This paper exploited the data reported in BK21 program of professors' research performances and analyzed the effects of reputational concerns on professors' research performances. According to the established theory of reputation effects in incentive provision, a professor's research incentive gets stronger if one's ability is less known, and one's colleagues' abilities are better known. We confirmed this theoretical hypothesis of reputation effects. Moreover, we found that a professor's research incentive was larger under inter-generational grouping in terms of age distribution and homogeneous grouping in terms of ability uncertainty.

  • This work is concerned with the investigation of end effects of a cylinder on a structure where a circular plate is attached to a solid circular cylinder. Three-dimensional elasticity solutions are used in a cylinder whereas the classical thin plate theory is employed for a plate. The end effect of the cylinder on the flexibility and the structural response is demonstrated by several numerical examples.

  • Exposure measurement data with parallel plate ionization chambers were known to depend on the polarity ($k_{pol}$) effect. In this work, the polarity effect were investigated for three parallel plate ionization chambers with different volume. The ionization chamber was fabricated using acrylic plate for the chamber medium and printed circuit board for electrical configuration. The various sizes of the sensitive volumes designed so far were 0.9, 1.9, and 3.1 co. High voltage generator was fabricated using the conventional 9 V batteries to apply the high voltage (300-500 V) to the electrode of the parallel plate ionization chamber. The gap between two electrodes ranged from 3, 6, and 10mm. As the result of our experiment, the polarity effect was within 0.5% in photon beam and 1% to 3.5% in the electron beams. Among electron beams, 16 MeV beam, which had highest energy, showed less polarity effect than electron beams with other energies.

  • Structural model of laminated composite plate based on the first order shear deformation theory and subjected to a combination of piezoelectric, electromagnetic and thermal fields is established. Coupled equations of motion are derived via Hamilton's principle on the basis of electromagnetic and piezoelectric equations which are involved in constitutive equations. Proportional control and velocity feedback control logics are applied via boundary control moments and forces. Variations of dynamic chasracteristics of composite plate with collocated piezoelectric sensor and actuators, electromagnetic field and temperature gradient are investigated and it reveals that dynamic characteristics of structure can be effectively controlled by utilizing the piezoelectric effect and ply angles of fiber reinforced composites.

  • 본 연구에서는 유한요소법을 사용하여 이방성으로 적층된 평판의 고유모드 를 예측하고, 이론적인 예측의 정확성을 연구하기 위해 사변 단순지지의 다 양한 각도로 적층된 정사각형 CFRP평판의 8번째 진동모드까지 실험적인 결 과와 비교하였다. 이 연구에서 사용된 모든 평판은 중앙면에 대칭이며, 이것 은 Bundling-stretching coupling을 제거하기 위해서이다. 그러나 만일 비대 칭적으로 적층된 평판이라면 이 효과를 포함한 해석이 되어야 할 것이다.

  • The combined convective heat transfer from vertical parallel plates with constant temperature has been studied by numerical method. The governing equations for the system are solved by the finite difference method and successive over relaxation scheme for Re$_{L}$ = 50 - 500, Gr = 10$^{4}$, Pr = 0.7. Results for various plate spacings and plate lengths are as follows ; For various plate spacings, the mean Nusselt number increases and then decreases as the dimensionless plate spacing increases. The optimum plate spacing for maximum mean Nusselt number decreases with increasing Reynolds number and can be expressed as a function of Reynolds number. For various plate lengths, the mean plate Nudest number increases as the dimensionless plate length decreases and Reynolds number increases.

  • 최근 주로 일본 해안공학자인 Hattori와 Matsumoto(1977), Aoyama 등(1900), Yu 등(1990)에 의하여 잠재평판(submerged plate)이 항만의 외곽 구조물로서 파랑 에너지의 저감에 미치는 영향에 대한 연구가 수행되어 왔다. Hattori와 Matsumoto(1977)에 의하면 장파에 대하여 평판구조물은 방파제로서의 역할을 못하는 것으로 판명됐으며 그리고 Yu 등(1990)의 실험결과에 의하면 평판의 길이가 전수심에 의한 파장과 동일하고 핑판위의 수심이 전수심의 0.2인 경우 0.8초의 단파에 대하여 투과율이 30%까지 감소되었다. (중략)

  • This paper analyzed the impact of nation and celebrity reputation on purchase intention in Kazakhstan. Kazakhstan people aged 10 to 30 years were surveyed. The study proved that the national reputation has positive impacts on the purchase intention of Korean products. However, the Korean celebrity reputation has not statistically affected the intention of purchasing Korean products. In other words, it confirmed that the country of origin effect of Korea is affecting purchases of products from the countries concerned. Therefore, based on the country's reputation for Korea in Kazakhstan, it is believed that the promotion activities of Korean products will encourage consumers to make purchases.
