  • Sometimes, it is more convenient to use paint-type and spray-type EM wave absorbers than bulk-type or sheet-type. Thus, in this paper, we prepared paint-type and spry-type EM wave absorbers. The proportion of ferrites to paints, particle size of magnetic material, and kinds of paint should be considered to prepare a superior paint-type EM wave absorber. There is no big gap between spray-type and paint-type in EM wave absorption of EM wave absorbers prepared with same composition.

  • Types (over parameters) in the theory of atomless random variable structures correspond precisely to (conditional) distributions in probability theory. Moreover, the logic (resp. metric) topology on the type space corresponds to the topology of weak (resp. strong) convergence of distributions. In this paper, we study metrics between types. We show that type spaces under $d^{\ast}-metric$ are isometric to Wasserstein spaces. Using optimal transport theory, two formulas for the metrics between types are given. Then, we give a new proof of an integral formula for the Wasserstein distance, and generalize some results in optimal transport theory.

  • This paper provides a fine-grained analysis of Korean serial verb constructions within the HPSG framework, and covers major descriptive characteristics of the phenomena. This paper discusses constraints on serial verb constructions in terms of four aspects; transitivity, argument structure, semantic properties, and complementizers. As a result, 17 constraints have been built, which support the type hierarchies for Korean serial verb constructions. This paper also presents a sample derivation on the basis of on the constraints and the type hierarchies.

  • If the completely observed data are assumed to have full information, the censoring causes the loss of information. Previous studies have introduced the indices of information loss via measuring relative changes between the data with censoring and without censoring. In this paper, the comparisons are made for the information loss between type I and type II censoring in two sample problems.

  • This study was to examine the occurrence of geographic song variation and its pattern of transitional direction among bush warbler populations distributed in Korea and Japan, Bush warbler songs (n=283) of 25 males from Cheongwon and Jeju, Korea, and from Chiba, Japan were analyzed. Chiba individuals had more song types and had the higher dominant frequency and longer duration of the introductory whistle portion than Cheongwon and Jeju individuals. In measure of eight song parameters, the parameters constantly showed a decreasing or increasing tendency. The constant tendency showed direction related with the geographic location from Chiba to Cheongwon. The difference in song parameters between Cheongwon and Chiba populations was the greatest in comparison to that of other sets of geographic populations. The degree of discrimination among the three populations was 92.00%. These results indicate that there is a geographic song variation between bush warblers of Japan and Korea, and that the song transition has been directed from Chiba (Japan) through Jeju to Cheongwon (Korea).
