This study was conducted to obtain the .basic informations for developing soybean varieties and mechanizing cultivation at the Crop Experiment Station, Rural Development Administration, Suwon, Korea in 1990. Two determinate soybean varieties, Hwangkeurnkong and Jangyeobkong, and two indeterminate soybean varieties, Clark and Williams were planted at three planting densities (33,22,16 plants / $m^2$). Number of branches and number of nodes on branches per unit area ($m^2$) were greater in determinate varieties than in indeterminate ones, and number of nodes on mainstem were greater in indeterminate varieties than in determinate ones. The higher planting density increased those characters. Seed weight per unit area ($m^2$) was higher in determinate varieties than in indeterminate ones, and it was great at the higher planting density. Indeterminate varieties showed greater mainstem dependence rate for yield components than determinate ones did. Harvest index was higher in indeterminate varieties than in determinate ones. The lower planting density increased harvest index. Stem dry weight per unit area($m^2$) was greater in determinate varieties than in indeterminate ones, and it was greater at the higher planting density. Variations among plants were great in the order of branch-related yield characters > total plant-re-lated yield characters > mainstem-related yield characters > morphological characters of mainstem and 100 seed weight. Difference between determinate and indeterminate varieties was significant in branch-related characters. Indeterminate varieties showed greater variations than determinate ones did in branch-related yield characters at different planting densities.

The competitiveness of 7 soybean (Glycine max (L) Men.) cultivars to weeds were studied. The two soybean cultivars that showed the greatest competitiveness to weeds by maintaining their yields were Suweon 83 and Dongbuktae; whereas the least competive were Columbus and Harosoy.

Analysis problems of tunnels whose geometrical dimensions are very small compared with surrounding media can be treated as infinite region problems. In such cases, even if finite element models can be applied, excessive number of elements is required to obtain satisfactory accuracy. However, inaccurate results may be produced due to assumed artificial boundary conditions. To solve these problems, a hybrid model, which models the region of interest with finite elements and the surrounding infinite media with infinite elements, is introduced for the analysis of infinite region. Three-dimensional isoparametric infinite elements with various decay characteristics are formulated in this paper and the corresponding parameters are presented by means of parametric studies. Three-dimensional tunnel analysis performed on a representative example verifies the applicability of hybrid model using infinite elements.

With the objective of analyzing changes in the education and curriculum of library and information science in China, this study conducts the following analyses. First, with respect to library and information science education, this study analyzed changes in terms of library and information science departments and majors being offered for undergraduate, graduate, doctoral, and post-doctoral training institutions from 2001 to 2012. Also, this study examined and analyzed colleges, areas, years of establishments and characteristics of 25 colleges that offers library and information science major. Second, with respect to library and information science curriculum, this study analyzed changes in the curricula of 1997 and 2006, while using China Education Ministry's 2003 main curricula of library science major as criteria and analyzed changes and characteristics of 2012 library and information science curricula of Wuhan University and Beijing University.

The main purpose of these studies was to obtain the basic informations necessary to develop soybean varieties. Two determinate soybean varieties, Hwangkeumkong and Jangyeobkong, and two indeterminate varieties, Clark and Williams were used to study the differences in growth and yield characters. Indeterminate varieties showed 30 days longer in days from intial flowering to terminal leaf stage and increased 7-8 more nodes on mainstem after initial flowering than determinate varieties. Determinate varieties were greater at middle-upper part, while indeterminate varieties were greater in middle part for the dry weight of the pods and stem at maturity. Total dry weight per unit area was greater in determinate varieties than in indeterminate ones from the early growth to maturity. However, the duration of vegetative growth was longer and the ability to keep leaf area index in the late growth stage was higher in indeterminate varieties. Variations among plants were greater in the order of branch related characters > mainstem, total vegetative, and yield related characters > morphological characters of mains tern and 100 seed weight. In general, variations of vegetative characters formed in the early growth stage were greater than those of yield characters formed in the late growth stage. On the other hand, the variations of those characters were greater in indeterminate varieties than in determinate ones. Variation of a seed weight within a plant was much smaller in determinate varieties than in indeterminate ones : i.e. coefficients of variation of a seed weight within a plant were from 13.6 to 13.8% in determinate varieties and were from 18.5 to 21.1% in indeterminate varieties, respectively.
