This study aimed to analyze the effect of demographic characteristics of consumers and quality recognition factors on purchase intention of organic wine, and to provide preliminary data necessary for the development of wine industry. By factor analysis of collected surveys, quality recognition factors of both the experienced and non-experienced group of organic wine environment/health, varieties of grapes, price, and four brand elements. First, among demographic characteristics, only income level hae a significant influence on the changes in quality recognition causes. Each of quality recognition causes of organic wine had a significant relation with purchase intent. The result of our analysis suggested that 'environment/health' was most influential for the experienced group, and 'health' was most influential for the non-experienced group. Therefore, this hypothesis is supported.

Rebar corrosion in concrete is one of the main causes of reduction of service life of reinforced concrete buildings. This paper presents the influence of rebar corrosion on the structural behavior of reinforced concrete (RC) buildings subjected to strong earthquake ground motion. Different levels of rebar corrosion scenarios were applied on a typical four story RC frame. The deteriorated conditions as a result of these scenarios include loss in cross-sectional area and loss of mechanical properties of the reinforcement bars, loss in bond strength, and loss in concrete strength and its modulus of elasticity. Dynamic analyses of the frame with different corrosion scenarios are performed with selected strong earthquake ground motion records. The influences of degradation in both concrete and reinforcement on structural behavior are investigated by comparing the various parameters of the frame under different corrosion scenarios with respect to each other. The results show that the progressive deterioration of the frame due to rebar corrosion causes serious structural behavior changes such as change in failure mode. The intensity, propagation time, and extensity of rebar corrosion have very important effects on the level of degradation of steel and concrete, as well as on the earthquake behavior of the structure.

The purpose of the present study was to investigate the degree of awareness toward child abuse behaviors, causes of child abuse, and the necessity of the parent education for child abuse prevention in the parents of elementary school students. Four hundred fifty parents of elementary school students participated for this study. The results were as follows. First, the parents generally were aware of emotional abuse and physical abuse, but not aware of neglect. In the comparison, according to parental education level and family income, highly educated parents and high-income parents were more aware of both emotional abuse and neglect. Second, most of the parents agreed on the causes of child abuse presented in the survey except the cause of having an unexpected child. Third, most parents agreed on the necessity of parent education programs for child abuse prevention. The discussion for the results and strategies for child abuse prevention was provided.

Evaluation of construction claims history can provide insights to improvement opportunities in a capital project portfolio. This study analyzed construction litigation claims extracted from the U.S. Court of Federal Claims (COFC) history involving the U.S. Naval Facilities Engineering Command (NAVFAC) from 1995-2004. Twenty-four total cases were examined over this period. Both "primary" causes and "root" causes were identified and compared to 666 litigation cases reviewed by the Armed Services Board of Contract Appeals (ASBCA). Based on the analysis, strategies for resolving future disputes are recommend using a 'hybrid' process prior to litigation.

Mengzi's biological analogies of man's moral tendency need to be analyzed in order to understand his ethical perspective because he uses lots of analogies to advocate his own moral naturalism. The biological analogies he uses are composed of human body, plant's seeds and sprouts. First, Mengzi thinks that human beings have inborn moral nature as if our bodies are given and plants can be grown from their seeds. His ethical approach to define morality in terms of natural properties such as the Four Sprouts(四端) causes a philosophical debate with Gaozi who thinks that morality cannot be described by natural property. Second, we have a moral preference as if we have a physical desire. This kind of moral sentimentalism emphasizing the preference is continued to Jeong Yakyong's ethical theory that nature is a preference(性嗜好說). Third, if we examine our preference and desire, then we can find that the moral preference is more valuable than the physical desire. Fourth, the biological analogies accepts monism that mind and body are composed of material force(氣). For this reason, the innate moral tendency is manifested on body such as a facial expression, a visceral reaction, and affect. Finally, Mengzi's theory of Four Sprouts causes two different interpretation. One is Zhuxi's interpretation that Duan端 is the visible end(緖) of a thread out of pack, the other is Jeong Yakyong's interpretation that Duan端 is a starting point(始) to cultivate virtues. While Zhuxi considers the Four Sprouts as a clue to find virtues in one's mind, Jeong Yakyong believes that we can cultivate our virtues by preserving the Four Sprouts.

Four leguminous crops grown in greenhouses and fields in Korea were surveyed from 2000 through 2002. Sclerotinia rot most severely occurred up to $60\%$ in Phaseolus vulgaris grown in greenhouses but occurred as low as $0-0.5\%$ in that grown in fields. Incidence of the disease in Pisum sativum grown in greenhouses ranged $1-5\%$, and that in Vicia Java and Vigna sinensis grown in fields was $0.8\%$ and $2\%$, respectively. Symptoms of Sclerotinia rot commonly developed on stems and pods of the crops. A total of 59 isolates of Sclerotinia species were obtained from diseased stems and pods of the crops. All of the isolates were identified as Sclerotinia sclerotiorum based on their morphological characteristics. Eight isolates of the fungus were tested for their pathogenicity to four host crops by artificial inoculation. All of the isolates induced rot symptoms on stems of the host crops tested, which were similar to those observed in the fields. The pathogenicity tests revealed that there was no significant difference in the susceptibility to the isolates among the leguminous crops tested This is the first formal report that S. sclerotiorum causes the Sclerotinia' rot of the four leguminous crops in Korea.

The taxonomy of Acanthamoeba spp., an amphizoic amoeba which causes granulomatous amoebic encephalitis and chronic amoebic keratitis, has been revised many times. The taxonomic validity of some species has yet to be assessed. In this paper, we analyzed the morphological characteristics, nuclear 18s rDNA and mitochondrial 16s rDNA sequences and the Mt DNA RFLP of the type strains of four Acanthamoeba species, which had been previously designated as A. divionensis, A. parasidionensis, A. mauritaniensis, and A. rhysodes. The four isolates revealed characteristic group II morphology. They exhibited 18S rDNA sequence differences of $0.2-1.1\%$ with each other, but more than $2\%$ difference from the other compared reference strains. Four isolates formed a different clade from that of A. castellanii Castellani and the other strains in morphological group lion the phylogenetic tree. In light of these results, A. paradivionensis, A. divionensis, and A. mauritaniensis should be regarded as synonyms for A. rhysodes.

An expert system is developed which can diagnose the causes and remedies of the failures of power transmission gears. The basic components of the expert system are knowledge base, inference engine, and working memory. The knowledges in knowledge base are classified into the knowledges for determining the failure types and for diagnosis of causes and remedies of the failures. The former is represented hierarchically into the main category of eleven groups by rules and the sub category of twenty four groups by facts, while the later is represented by facts according to the each group of knowledges. In the inference engine some considerations are implemented, i.e., the backward chaining method and depth first search to determine the category of the failures, the meta-knowledges to shorten the search space, the certainty factor to evaluate the reliability of result, and the unification strategy to diagnose the causes and remedies of the failures. The working memory is established to hold the results during inference temporarily. In addition, knowledge acquisition facility, explanation facility, and user interface are included for the usefulness of user. This expert system is written with the PROLOG programming language on IBM-PC compatible computer operated by MS-DOS and be executed alone.
