The purpose of this study was to develop a skirt pattern drafting method for korean women between the ages of $18\~24$ on the basis of their physical charcteristics which differs from those of other races in its size and figure. The study procedures and results were as follows; 1. Ten types of convantional skirt patterns were collected and compared to determine the essential measuring items for skirt construction, and to discover what problems are involved. 2. Fourteen items of KIST measurement data were analysed for correlation coefficients, to establish representative items and independent ones. 3. Front waist length and back waist length were additionally measured for supplementary data. 4. A new skirt drafting method was developed based on the results of the pattern comparison and the data analysis. 5. A sensory evaluation was applied to evaluate the new method comparing it with the most widely accepted conventional pattern. An original rating scale was developed for the evaluation and an expert panel consisting of five members judged each shell from 12 subjects by random selection. According to a statistical analysis of the result of the 17 items on the rating scale, 14 items showed significant differences (${\alpha}\leqq$0.01 or ${\alpha}\leqq$0.05) between the two, with the new pattern having better fit. The new pattern drafting method proved to be superior to the conventional one especially in the fitness at the back hip, dart length, side seam balance, and the ease for daily activities.

The porpose of this research is helping product developments and establishment men's marketing strategies. This contents are divided into two parts; the dress shirt's wearing condition and the dress shirt's buying condition. The subjects of the research were male that aged 25-50 and their company is resided in Seoul. The conclusion of this research is summarized as below ; 1. Many consumers have wrong term recognition of dress shirt. Most of men know their dress shirt's sizing designation as casual method(ex, $\cdots$95, 100$\cdots$). Therefore it is happened fitness complains. Dress shirt's wearing frequency for a week is 1-2 days or 5days mostly. A number of dress shirt’s wearing period for one is 6-12 months. Dress shirt‘s wearing frequency fand wearing period varies according to their age, unmarried or married situation, scholarship, occupation. So the manufacturer of men's dress shirt grasps the factor's for their character. 2. The conclusion of dress shirt's buying motivation is need better than impulse buying. If company planning season event, the selling will be improved. Most of men buy their dress shirt by themselves. It means a lot of men are interested in their clothes comparing to old days. And men's favorite purchase place is a department store and agent. when they purchasing, the color and size is very important factor. But dress shirt's sizing designation is not yet established. Therefore the dress shirt's sizing designation is needed as possible.

일련의 새로운 3-benzylidenemyosmine 유도체들의 구조 변화와 미국 바퀴벌래(Periplaneta. americana L.)의 nicotin acetylcholine 수용체 (nAChRs) 사이의 결합 친화력 상수에 관한 정량적인 구조와 활성과의 관계를 분자 홀로그램(H) QSAR 방법으로 검토하였다. 친화력 상수에 관하여 가장 양호한 HQSAR 모델은 분자조각 크기 5${\sim}$8 bin 조건에서 유도된 모델(IV-2)이었다. HQSAR 모델(VI-2)은 높은 예측성(q$^2$=0.507)과 상관성(r$^2_{nev.}$=0.944)에 근거하여 양호한 통계값들을 나타내었다. 그리고 HQSAR 기여도로부터 결합 친화력 상수는 분자내 anabaseine 고리에 의존적이었으며 결합 친화력성이 높은 화합물들이 최적화된 모델(VI-2)에 의하여 설계되었다.

Lee[15] examined quantity discount contracts between a manufacturer and a retailer in a stochastic, two-period inventory model where quantity discounts are provided based on the previous order size. During the two periods, the retailer faces stochastic (truncated Poisson distributed) demands and he/she places orders to meet the demands. The manufacturer provides for the retailer a price discount for the second period order if its quantity exceeds the first period order quantity. In this paper we extend the above two-period model to a k-period one (where k < 2) and propose a stochastic nonlinear mixed binary integer program for it. In order to make the program tractable, the nonlinear term involving the sum of truncated Poisson cumulative probability function values over a certain range of demand is approximated by an i-interval piecewise linear function. With the value of i selected and fixed, the piecewise linear function is determined using an evolutionary algorithm where its fitness to the original nonlinear term is maximized. The resulting piecewise linear mixed binary integer program is then transformed to a mixed binary integer linear program. With the k-period model developed, we suggest a solution procedure of receding horizon control style to solve n-period (n < k) order decision problems. We implement Lee's two-period model and the proposed k-period model for the use in receding horizon control style to solve n-period order decision problems, and compare between the two models in terms of the pattern of order quantities and the total profits. Our computational study shows that the proposed model is superior to the two-period model with respect to the total profits, and that order quantities from the proposed model have higher fluctuations over periods.

Some CMP gathers acquired from shallow marine seismic reflection survey in offshore Korea do not show the hyperbolic trend of moveout. It originated from so-called swell effect of source and streamer, which are towed under rough sea surface during the data acquisition. The observed time deviations of NMO-corrected traces can be entirely ascribed to the swell effect. To correct these time deviations, a residual statics is introduced using Genetic Algorithms (GA) into the swell correction. A new class of global optimization methods known as GA has recently been developed in the field of Artificial Intelligence and has a resemblance with the genetic evolution of biological systems. The basic idea in using GA as an optimization method is to represent a population of possible solutions or models in a chromosome-type encoding and manipulate these encoded models through simulated reproduction, crossover and mutation. GA parameters used in this paper are as follows: population size Q=40, probability of multiple-point crossover P$_c$=0.6, linear relationship of mutation probability P$_m$ from 0.002 to 0.004, and gray code representation are adopted. The number of the model participating in tournament selection (nt) is 3, and the number of expected copies desired for the best population member in the scaling of fitness is 1.5. With above parameters, an optimization run was iterated for 101 generations. The combination of above parameters are found to be optimal for the convergence of the algorithm. The resulting reflection events in every NMO-corrected CMP gather show good alignment and enhanced quality stack section.

Queen honey bees (Apis cerana) can be reared artificially on demand by the use of grafting technique. The technique consists of grafting young worker larvae into queen cell cups and raising in a queenless strong colony. As the age of grafted larvae for queen rearing exhibited several aspects related to quality and reproductive potential of queen, this study were conducted to investigate the influence of age of grafted larva on morphological characteristics and lifespan of queen, and the growth of colony she headed. Our results demonstrated that queens reared from young worker larvae (i.e., less than 1-day old larvae) were significantly larger in size (i.e., body weight and thorax width) than that of queens reared from 2-day old worker larvae. Moreover, queens reared from younger worker larvae initiated egg-laying earlier, stored more spermatozoa in spermatheca and had a longer lifespan compared to queens raised from older worker larvae. We also found a significant positive effect of queen grafting age on the production of worker and drone brood, adult worker population in colonies headed by queens reared from younger larvae. These findings suggested that rearing queens from brood grafted at the earliest possible age could increase the reproductive potential of queen as well as fitness of colony she head.
