In order to obtain the genetic information on the quantitative characters of black seeded soybeans, which would be needed to improve selection efficiency for breeding high yielding genotype, 45 varieties of black seeded soybeans collected in Chonnam, Korea were grown and variations of several important characters were observed. Heritability of each observed character, phenotypic and genotypic correlations among the characters and contribution of each yield component on grain yield through path coefficient analysis were estimated. Both number of pods per plant and 100-seed weight showed not only high heritability but also highly significant phenotypic and genotypic correlation with seed yield, and hence it was desirable to select plants with more number of pods per plant and higher 100-seed weight than raise seed yield of black seeded soybeans collected in Chonnam. In addition, number of pods per and 100-seed weight were proved to be the most influential variables on the viability of seed yield by path coefficient analysis. Since these showed the high heritability of number of pods per plant, selection of plants with higher 100-seed weight would be more efficient for breeding high yielding genotype.

Analysis on the Value Chain Structure of Musical Satisfaction Using Path Analysis Kim, Haw-rye/Kwon, Byung-woong/Kim, Youn-tae Path analysis is a form of statistical analysis used to examine therelationships betweenvariablesand its advantage is to enable direct effect, indirect effect and spuriouseffect which are hard to identify by regression analysis. Using path analysis, this study examined the value chain structure of musical elements such as distribution, planning, production and consumption which are expected to affect musical satisfaction. The selected population was Seoul Citizens who watched musicals at least one time and, through random sampling, 250 were selected as sample at eight musical theaterslocated in Daehakro, Chungmuro, etc. in Seoul. Among the questionnaires collected from the 250 samples, 212 were used for this study except 38 unfit for analysis. Survey is composed with total of 24 questions which include 6 demographic questions, 17 audience tendency questions and 18 satisfaction questions. We made value chain structure analysis by dividing each level of satisfaction in planning, manufacturing, distribution and consumption and executing subsequent factor analysis in those satisfaction questions. Study results after reliability analysis of 18 satisfaction level questions showed high level of 0.893 reliability coefficient and therefore, we can tell there exists high level of internal consistency in each factor.

The development of flexible automation in the manufacturing industry is concerned with production activities performed by unmanned machining system. A major topic relevant to metal-cutting operations is monitoring tool wear, which affects process efficiency and product quality, and implementing automatic tool replacements. In this paper, the measurement of the cutting force components has been found to provide a method for an in-process detection of tool wear. The static components of cutting force have been used to detect flank wear. To eliminate the influence of variations in cutting conditions, tools, and workpiece material, the force modeling is performed for various cutting conditions. The normalized force disparities are defined in this paper, and the relationships between normalized disparity and flank wear are established. Finally, artificial neural network is used to learn these relationships and detect tool wear. According to the proposed method, the static force components could provide the effective means to detect flank wear for varying cutting conditions in taming operation.

權錫杞,南允基 홍익대학교 산업기술연구소 1995 産業技術 Vol.5 No.-

Several types of blocking reactions between diisocyanates and blocking reagents have been tried to obtain better raw materials for polyurethane varnishes. The existence of catalyst have been found to be the most important factor for the NCO blocking reactions of TDI and MDI. For blocking reagents. aliphatic alcohol showed better reactivity than aromatic because of less steric hindrance. All most all of the NCO groupes have been blocked very easily with any types of catalyst such as base amine and organometallics. Among them. Dabco and N.Nidimethyl cyclohezylamine were jound to be best catalysts for the these types of NCO blocking reations.

Background : The application of the delta check in tests in general chemistry detects both random and clerical errors, thus enhancing the reliability of tests. However, since this approach adds the burden of confirming the results to the laboratory, it has the disadvantage of lengthening the turn around time of tests. We speculated that an online delta check system needed to reduce the turn around time. We developed delta quality control system and evaluated its effectiveness of quality control in clinical chemistry. Methods : We developed an online delta check system based on the client-server paradigm. We used IBM PentiumⅢ PC as server and as clients. The database system used was powerbuilder 6.0. Results : In the system we developed, delta screening was performed when test results were input to the computer. The decision over the delta screening was made by comparing it against patient's clinical information and cumulative results within the same screen. Conclusions : The developed delta check method made it available to reduce the turn around time previously spent on delta screening by eliminating the batch processing of tests which was needed in previous approaches separate query cumulative results and patient's clinical informations for screening purposes.

A method of state assignment for CMOS synchronous finite state machines is described, which is effective for minimizing power dissipation in flip-flops. The method is based on a model that power dissipation in flip-flops is assumed to be proportional to average frequency of flip-flops' output states change. The minimum state code assignment obtained in this method is such that the Hamming distance of state codes, for a pair of states with a transition, is one. A minimum algorithm for the state code assignment is described along with examples. Results of this method becomes a criterion of state code assignment for reducing power dissipation of CMOS circuits. Finally, the topics in this paper are overviewed and several future problems are discussed.

The present study was carried out to investigate the potential acute toxicity of safflower seed by a single oral dose in ICR mice. Twenty animals of each sex were randomly assigned to four groups of 5 rats each and were administered singly by gavage at dose levels of 0, and 2,500 mg/kg bodyweight. Mortalities, clinical findings, and body weight changes were found and complete gross postmortem examinations were performed. Throughout the study period, no treatment-related deaths were observed. There were no adverse effects in clinical signs, body weight, and gross findings at any dose tested. The results showed that the single oral administration of safflower seed did not cause any toxic effect at the dose levels of 2,500 mg/kg in rats and the minimal lethal dose was considered to be over 2,500 mg/kg body weight for both sexes.
