Factorial experiments are studied in this paper. The Designs, thus, have factorial balance with respect to estimable main effects and interactions. John and Lewis (1983) considered generalized cyclic row-column designs for factorial experiments. A simple method of constructing confounded designs using the classical method of confounding for block designs is described in this paper.

Designs for polynomial approximation to the unknown response function are considered. Optimality criteria are monotone functions of the mean squared error matrix of the least squares estimator. They correspond to the classical A-, D-, G- and Q-optimalities. Optimal first order designs are chosen from the invariant designs and then compared with optimal second order designs.

This study proposes 3D printed shoe designs with patterns made by reinterpreting traditional Korean muntin patterns as customized designs that are unique to individual consumers and different from existing products. In the fashion industry, shoes with diverse designs grafted with 3D printing technology have been introduced. Artistic 3D printed shoes showcase the unique designs of designers. Functional and practical 3D printed shoes that can be worn during daily activities and during exercise have been actively developed. Traditional Korean pattern designs are also being recreated into designs reflecting the aesthetic sense of modern times with our own identity. The uniqueness of the traditional muntin patterns in geometric shapes, such as intersections of lines, rectangles, and octagons, are expressed in shoe designs with modern aesthetic senses by utilizing the traditional patterns that conform well to the modern geometric beauty of forms. This study was intended to develop 3D shoe designs that reinterpreted the motif of muntin patterns from among traditional Korean geometric patterns with a modern aesthetic sense. The octagonal patterns that express the scenery of spring can be seen through the muntins in traditional Korean-style houses were designed on the heels of shoes. Utilizing the Rhino CAD program and ProJet 660 Pro 3D printer, shoes were designed and printed. The processes for making shoes using 3D printing technology proposed in this study are significant because they represent the creation of designs in a new area. The results of this study might help in the development of 3D printed fashion products.

실험계획법의 강의내용은 크게 두 개의 파트인 실험계획과 모형분석으로 대별되는데 시각화 작업은 주로 모형분석 중심으로 이루어져 왔다. 실험계획법의 강의내용에 대한 시각화 작업의 일환으로 우리는 실험계획의 시각화를 라틴 방격법의 시각화, 초포화계획법의 시각화, 불완비블럭계획법의 시각화로 나누어 고려하여 볼 수 있다. 실험계획을 시각화하는 작업을 위하여 우리는 계획그림을 제안 할 수 있고 기존의 산점도나 산점도행렬을 사용할 수 있다. 이러한 실험계획의 시각화를 통하여 우리는 이론 중심의 실험계획법 강의에 그림들을 삽입함으로써 실험계획법 수업에서의 시너지효과를 얻을 수 있다.

A class of block designs for general combining ability comparisons within two groups of inbred lines in diallel crosses is given. These block designs are constructed by using balanced block designs obtained by cyclically developing a single initial block. Also, the efficiencies of block designs are tabulated for number of lines 26 or less.

Confounded row-column designs for factorial experiments are studied in this paper. The Designs, thus, have factorial balance with respect to estimable main effects and interactions. John and Lewis (1983) considered generalized cycle row=column designs for factorial experiments.

It is well known that $L_2(m)$ type PBIB designs have the Property A, so they are BNAS PBIB designs. However, $L_3(m)$ type PBIB designs are not of type of Property A but do have the factorial structure (Cotter, John, and Smith(1973)). In this paper, the properties of the $L_3(m)$ type PBIB designs are investigated. Extended Property A and fractional BNAS are defined and a solution formula for the treatment effects in the $L_32(m)$ type designs is obtained.

In this paper, block designs for control versus test comparisons among the lines for diallel crosses are proposed. These block designs are constructed by using balanced incomplete block designs. Also, the efficiencies of the diallel crosses block designs obtained through this method are tabulated for number of lines 23 or less.

In this paper, orthogonal block designs for partial diallel crosses are proposed. These partial diallel crosses block designs for estimating general combining abilities are constructed by using $\alpha$-resolvable partially balanced incomplete block designs. Also, the efficiencies of the partial diallel crosses block designs obtained through this method are reported in table.
