This study aims to examine Mark Twain's criticism of American capitalistic ideals in the late nineteenth century. During this second industrial revolution, industry showed rapid growth and capitalism established an order, while America suffered under the monopolization of capitalistic conglomerates. This resulted in the widening gap between the rich and the poor and the dehumanization caused by rapid industrialization. In A Connecticut Yankee in King Arthur's Court, Hank Morgan, the protagonist--who represents nineteenth-century America's industrialism, individualism, and capitalism--is sent back in time to the sixth century of Arthurian England. Hank attempts to introduce nineteenth-century technologies and machines to build a capitalistic system in the middle ages. However, Hank's efforts lead to disaster in which the country and civilization he worked to build is completely destroyed. Although Twain does not deny capitalistic ideals, he criticizes the "governmentality" that operates Hank's reform system to the extreme. Hank values efficiency and utilizes human beings as capital. Hank's economic reason not only transforms the Round-Table knights into speculators but also transforms their religious acts and abstract ideals into moneymaking businesses. The destructive ending anticipates the World Wars and the Great Depression in the first half of twentieth century and even serves to predict the dangers that follow.

The present study investigated the influence of parental behavior on their children's dating violence and the pathways by which parental behavior affected their children's violent acts in their respective dating relationships. The related variables in parental behavior were marital violence, child abuse, and parental support. This study identified whether parental violence and support behavior effected dating violence, and if that dating violence was in any way mediated by conflict resolution skills, depression, or delinquency. In addition, the study examined any differences between males and females that were affected by parental behavior. Subjects included 760 students from 14 of the universities in and around Seoul. The Structural Equation Model(SEM) was employed to fulfill the study objectives. The SEM results were the following: The experience of child abuse was associated with severe forms of dating violence, and was only mediated by delinquent acts. Such outcomes were consistent across genders. In this data set, in contrast to the previous studies, the observation of parental violence was not related to children's violent behavior. According to the analysis of SEM, parental support rather than parental violence was more likely to influence their children's dating violence. The lower the level of parental support the greater the negative affect on children's conflict resolution skills, depression, and delinquency, which in turn had an influence on their dating violence. More specifically, an attitude of parental neglect adversely affected women's conflict resolution skills, and increased the frequency of male delinquent behavior. In the light of these findings, practical implications for decreasing dating violence were discussed.

In this paper, a 16${\times}$16-bit Multiplier and Accumulator (MAC) is designed using a Redundant Binary Adder (RBA) circuit so that it can make a fast addition of the Redundant Binary Partial Products (RB_PP's) by using Wallace-tree structure. Because a RBA adds two RB numbers, it acts as a 4-2 compressor, which reduces four inputs to two output signals. We propose a method to convert the Redundant Binary (RB) representation into the 2's complement binary representation. Instead of using the conventional full adders, a more efficient RB number to binary number converter can be designed with new conversion method.

According to growing of the plant cultivation in a greenhouse environment, the demand of a system to control the greenhouse easier has increased. Currently, the methods to control by the mobile App represent the information in a greenhouse environment with a simple numerical data or compose only the contents with a limited degree of freedom. In order to solve these problems, this paper presents a system that can be viewed or controlled greenhouse conditions in near / remote distance using augmented reality and MQTT communication protocol, RTSP media streaming protocol. The proposed method is implemented in Android smartphone environment and acts monitoring the information (temperature, humidity, illuminance) obtained by greenhouse's sensors and transmits the real time greenhouse's video using RTSP in the remote distance, and controls the values of temperature, humidity, illuminance for the greenhouse using the augmented reality in the near distance.

In Korea, buckwheat has historically held a very important position because it has been used as a food and traditional medicine. The objectives of this report were to mainly review the up to present papers includings 75 references about buckwheat's rutin, functional ingredients and their variations. Buckwheat provides an abundance of such nutrition as protein, amino acids, vitamin($B_1,\;B_2$, E, P), minerals(Fe, Zn, Mn, Mg, P, Cu, Ca, Se) and dietary fiber. Buckwheat's essential amino acid, lysine, is notably higher amount than cereals. Rutin(vitamin P), one of a group of flavonoids, is abundant in buckwheat and noted for its beneficial function of reducing every kinds of radiation and vascular diseases, diabetes mellitis and retinal hemorrhage, etc. Rutin also acts as a pigment stabilizer and acetone extracts of buckwheat have a potent tyrosinase inhibitory activity.

This study presents the eigen ethnic function and mathematical processing method of human information. Human information can be definded as the overlap area taking the superposition property composed of intuition and sensory in stimulus/response (S/R) model, In S/R model, the intuition and sensory eigen ethnic function acts on the forming of perception. Perception process by the superposition property of intuition and sensory analogy to the basic neural network model. This analogy model extends to the analysis method. As an analysis method, optimal ratio number induced to the golden section ratio. Golden section ratio drived out by diverse source and implicated to the sensory and intuitive context such as beauty, harmony, optimality etc. This numerical orders can be applied to analysing the Perception process and extended to pursue the Potential human behavior, On the basic of proposed applying method, an illustrative mathematical examples are presented.

Purpose: The purpose of this study was to analyze metacommunicative episodes comprised of nurses' metacommunicative behavior and children's responses occurring in the dyads of nurse-child within the context of an inpatient pediatric unit. Methods: Twelve dyads of nurses and children were videotaped for four hours each day over a two-day period as they interacted with each other on the inpatient unit. The metacommunicative episodes were recorded from the videotapes. The metacommunicative behavior was categorized within Shin's metacommunicative behaviors. Results: The total number of episodes between the nurses and children included in this study was 242. The most frequently used metacommunicative behavior was 'reflection', followed by tagging, baby talk, approaching, mediating eye level, friendly demand, encouraging, description of acts, symbolization, turnabouts, touching, and mimic voice, respectively. The most common response to the nurses' metacommunicative behavior was agreeing, followed by tension release. Conclusion: Young children responded positively to metacommunicative behavior by the nurses. Understanding metacommunicative behavior may help nurses approach their young patients more easily and with confidence.

Effects of particulate size and frictional characteristics were examined on the melting behavior of PP(polypropylene) in a twin screw extruder. Powder and pellet types of PP were used and each component was blended with PE(polyethylene) wax and clay, respectively. It was observed that small size particulates, 1.e. powder systems exhibit accelerated melting behavior; and it was also found that the abrasive auditive acts as an effective agent for fast melting of PP powder. Retardation of melting due to the reduced friction was observed in both types of PP, contrary to the result found in a batch mixer. The tendency observed in variation of torque and exit temperature was explained in terms of frictional effect and length of compacted region formed during evolution of melting.
