In this paper we propose nonparametric tests using optimal weights for umbrella alternatives in a randomized block design. We obtain the optimal weights by maximizing the asymptotic relative efficiency of the proposed test statistics with respect to Mack and Wolf(1981) type test statistic, and investigate asymptotic relative efficiencies of the proposed test statistics using these optimal weights relative to Mack and Wolfe type statistics and linear rank statistic. Throughout simulations for small samples, the proposed test statistic has good powers rather than the other two tests when the block sizes are different.

A nonparametric test for the parallelisim of k regression lines against ordered alternatives is proposed. The test statistic is weighted Jonckheere-type statistic applied to slope estimators obtained from each lines. The distribution of the proposed test statistic is asymptotically distribution-free. From the viewpoint of efficiencies, the proposed test desirable properties and is more efficient than the other nonparametric tests.

3대 문학상을 주관하고 수상소설집을 발간해온 3사와 가람기획간의 출판권 침해에 관한 공방은 법적인 송사로 번지기 직전의 첨예한 대립양상을 보인다. 이번 사건은 표면적으로는 출판사 사이의 분쟁으로 보이지만 그 이면에는 저자와 출판사간의 저작권 계약문제가 잠복해 있다.

정부가 잇따라 부동산 대책을 발표하고 있지만 시장에는 여전히 찬바람이 분다. 국회에서도 여야가 부동산 규제 완화안에 대해 날카롭게 대립하고 있다. 하지만 여야 모두 결국 부동산 시장 정상화라는 대명제 아래 세부 시행 방안에 대한 이견이 있을 뿐이다. 국회에 바라는 각계의 의견을 들어보자.

세계가 미·소양국으로 나뉘어져 냉전 상태로 대립되어 있을 당시 동서 양진영은 경쟁적으로 군비를 확충하고 새로운 성능을 가진 항공기나 무기를 개발하는데 치열한 우위다툼을 전개했었다. 서로 조금이라도 선두에 서기 위하여 한걸음을 두고 맞선 결과는 먼저 전투기 분야에서 괄목할만한 진보를 가져왔다.

Isozyme variations in 4 enzyme systems in Pinus densiflora for. multicaulis in 31 individual trees collected throughout the country were studied by starch gel electrophoresis using haploid megagametophyte tissue to compare with those of Pinus densiflora. A minimum of 7 loci were found to code for isozymes of the enzyme systems. No variation was found at locus GOT-A; at the remaining 6 variable loci(GDH-A, GOT-B, GOT-C, IDH-A, LAP-,A, LAP-B) and 2 to 4 alleles were identified. We could not find any marker alleles to distinguish Pinus densiflora for. multicaulis from Pinus densiflora at the isozymes studied here. Allele frequency distributions at each loci were almost all the same as those of P. densiflora. The percentage of polymorphic loci(99% level), the number of alleles per locus, the observed and expected heterozygosities were 85.7, 2.3, 0.165 and 0.186%, respectively. The level of genetic diversity in Pinus densiflora for. multicaulis seemed to be less than that of P. densiflora.

To find ideal leaf types for soybean breeding program, we examined the relationships among leaf anatomical and morphological characteristics and $\textrm{CO}_2$ assimilation on the different leaflet shape of soybean (Glycine max). In anatomical characters of leaf, palisade and spongy cells were thicker in both small seed cultivars with narrow leaflet and large seed cultivars with wide leaflet than others. $\textrm{CO}_2$ uptake per plant and leaf thickness were significantly associated with seed yield per plant, showing difference among the soybean cultivars. Although the leaf area was lower for narrow leaflet cultivars, which had a significantly higher photosynthetic rate per plant comparable to the wide leaflet cultivars.
