One of the problems facing international companies is the question of whether to use standardized international advertising or to adapt advertising messages in each country. This paper provides empirical evidence for whether or not to be able to use standardized advertising based on a comparison of evaluative criteria for automobiles and toothpaste among American, Japanese, and Korean consumers. There appears to be a similar pattern among respondents of the three countries in rank of attribute importance. Especially, the result of toothpaste shows an almost identical pattern. The findings do support the idea that international advertising can be standardized due to the similarities among world-wide consumers.

Slow seedling growth rate and nodulation failure of white clover (Trifolium repens L.) has been limited its good establishment to pastures. The experiment was done to determine the effect of removal of cotyledon and unifoliolate on the shoot, root growth,

균 열전 파 현상은 항상 형상이 변화하는 대표적인 문 제줌의 하나이다. 본 연 구는 준-정적 균열전파 현상올 해석하기 위 하여 듬로네이 특성을 이용한 국지 요소재편 알고리즘을 제시하였다. 이 알고리즘은 요소 재편성 과 세 분 화를 모 두 수행할 수 있도록 준비되었다. 적용예로 M 적분볍올 사용하여 주로 혼합 모우드로 균열이 전파되는 스폴링 현상을 해석하였다.

We investigate the dynamical evolution of globular clusters under the diffusion, the Galactic tide, and the presence of halo black holes. We compare the results with our previous work which considers the diffusion processes and the Galactic tide. We find the followings: (1) The black holes contribute the expansion of the outer part of the cluster. (2) There is no evidence for dependence on the orbital phase of the cluster as in our previous work. (3) The models of linear and Gaussian velocity distribution for the halo black holes do not show any significant differences in all cases. (4) The perturbation of black holes reduces the number of stars in lower energy regions. (5) There is a significant number of stars with retrograde orbits beyond the cutoff radius especially in the case of diffusion and the perturbation of black holes.

The 3mm transitions to CO, 13CO, CS, HCO+, and HCN have been observed toward the compact HII regions in W58 using the 14m Daeduk Radio Telescope (DRT). Some of the observed lines show high-velocity wings resulted from outflowing materials of the compact HII regions. We derive the beam averaged column densities of the observed species and compare their relative abundances. The HCO+ abundance appears to be smaller by about an order of magnitude than those of 'typical' quiet molecular clouds. CS may be a good reference molecule in comparing relative abundances in different physical conditions.

We have observed the emission of HC3N J=4-3, 5-4,10-9 and 12-11 transitions toward the Sgr B2 central region in an area of $150 with resolutions of 16'-48'. The intensities and central velocities of line profiles show significant variations with positions. In contrast to the intensities of the low J-level transitions which gradually increase from the central source toward the outside region, the HC3N emission of the high J-level transition become stronger toward 'the central radio continuum source MD5. Systematic change in the radial velocity of each line profile occurs along north-south direction. There are a few peaks in most line profiles, and these indicate that there are multiple velocity components along the line of sight. Distributions of excitation temperature and column density which were estimated from the excitation calculations show the existence of a small (1 X 2pc), hot (Tex>50K) core which contains two temperature peaks at-15' east and north of MD5. The column density of HC3N is (1-3)X1014cm-2 Column density at distant position from MD5 is larger than that in the central region. We have deduced that this 'hot-core' has a mass of 105M⊙, which is about an order of magnitude larger than those obtained by previous studies.
