This study aims to find out the argument structure which appears in the type of argument class (teacher- and student-centered) of the high school. The argument structure was compared and analyzed according to analyzing the study achievement and verified the academic achievement related to climate change. The results are listed below. First, the student-centered class is more effective method through the result that analyzed the class type of the teacher in argument-centered class. This result is to suggest more effective method to revitalize the argument activity of students-centered class which students plan for themselves and find more various materials. Second, teacher-centered class is more effective in contrast with argument analysis in the academic achievement test. While this is why the teacher-centered class utilizes an essential data necessary to curriculum in the argumentation, the elements to form the argument increased because students utilized the materials with their interest and concern in the process of proving in the student-centered class. Through the results of the research, it is necessary to develop the argument-centered programs for the science class and the curriculum-centered materials for argument class activity.

$Bi_{2}Te_{3}-Sb_{2}Te_{3}$, $Bi_{2}Te_{3}-Bi_{2}Se_{3}$ solid solutions are of great interest as materials for thermoelectric energy conversion. One of the key technologies to ensure the efficiency of thermoelectric device is to obtain chemically homogeneous solid solutions. In this work, the new process with rapid solidification followed by hot pressing was investigated to produce homogeneous thermoelectric materials. Characteristics of the materials were examined with XRD, SEM, EPMA-line scan and bending test. Property variations of the materials were investigated as a function of variables, such as excess Te quantity and hot pressing temperature. Quenched ribbons are very brittle and consisted of homogeneous $Bi_{2}Te_{3}$, $Sb_{2}Te_{3}$ solid solutions. When the process parameters were optimized, the maximum figure of merit was 3.073$\times$$10^{-3}K^{-4}$. The bending strength of the material, hot pressed at 45$0^{\circ}C$, was 5.87 kgf/${mm}^2$.

This research examined children's perception of parental authority within three different types of rules : moral, social-conventional, and personal issue. Specifically, two major aspects of parental authority-legitimacy and obedience-were explored. The subjects of this study were 120 children from an elementary school in Kwangju. There were 40 subjects (20 males and 20 females) in each of three age groups: 7-, 9-, and 11- year-olds. The subjects were administered an interview individually. Based on Tisak (1986) open-ended questions concerning three family rules (moral rule, social-conventional rule, personal issue) were administered. Responses to the assessment questions were coded as positive or negative. Responses to the judgment conception questions were coded into 7 categories : Other's Walfare, Social Coordination, Personal choice, Deservedness of Punishment for Wrongdoing, Existence of Authority, Conflicting Personal Interest and Authority, and Personal Development. Statistical analysis of obtained data was by percentage and ${\chi}_2$ test using log linear procedure. The results were as follows : (1) There was a significant main effect of type of rule on the children's assessment regarding legitimacy and obedience of parental authority. The children (average 96%) stated that it was all right for parents to make rules prohiliting an act when it pertained to moral and social conventions. However, the majority of the children (average 40%) stated that it was not right for parents to regulate personal issues. (2) There was a significant interaction effect between type of rule and age. (3) There was a significant main effect of rules on the children's judgment conception of parental authority. (4) There was a significant interaction effect between rules and ages on children's judgment conception of parental authority.

Diamond-like carbon(DLC) films are considerable research interest because of their widespread applications as protective coatings in areas such as optical windows, magnetic storage disks, car parts, biomedical coatings and as micro-electromechanical devices(MEMs). DLC films were deposited on WC-Co by PECVD using Ar, $C_2H_4$ gas. Tribological tests were conducted using a ball-on-disk type tribometer in dry air. Three kinds of counter-bodies balls were used. The counter-bodies balls are SM45C, SUJ2 and $ZrO_2$(3.17mm in diameter). Wear rate of the samples were calculated after measuring the worn-out volume of the wear track. As results wear test, the higher hardness of counter-bodies, friction coefficient low. As result of XPS estimation, wear debris generated as an oxide lower the friction coefficient.

The interest in the dynamic properties of soils has increased strongly because of earthquake, heavy traffic, and foundations undergo high amplitude of vibrations. Most of soils in Korean peninsula are composed of granite soils, especially the decomposed mudstone soils are widely spread in Pohang areas, Kyong-buk province. Therefore, it is very important to investigate the dynamic properties of these types of soils. The most important soil parameters under dynamic loadings are shear modulus and material dampings. Furthermore, few definitive data exist that can evaluate the behavior of unsaturated decomposed mudstone soils under dynamic loading conditions. The investigations described in this paper is designed to identify the shear modulus and damping ratio due to a surface tension for the unsaturated decomposed mudstone soils under low and high strain amplitude. For this purpose, the resonant column test and the cyclic triaxial test were performed. Test results and data have shown that the optimum saturated degree of decomposed mudstone soils under low and strain amplitude is $32{\sim}37%$ which is higher than that of decomposed granite due to the amount of fine particles as well as the type and proportion of chief rock-forming minerals.

This study was carried out using personal measurement for female college students who have a great interest in fashion at 20-24 age, and examined somatotype character. As a means of a character type test, the grades were laid by using MBTI which proved to be objective, and relativity between character types was laid by conducting correlation analysis. The conclusions which can be drawn from this study are as followed. 1. In 4 preference index, which was classified by MBTI, Sensing(S) type was the highest of 17.27% at the average and 68.5% at the distribution rate each. The average of Extraversion(E) type was 14.56% and it's distribution rate was 64.5%. Index of types were : Intuition(N) 12.49%, Introversion(I) 11.75%, Perceiving(P) 12.50%. Average distribution rate of each types were : N 31.5%, I 35.5%, P 40.3%. And average of Sensing(S) type was the lowest, 11.09%. Like American Students, the subjects of this study showed higher in the E type than in the I type. The distribution rate of 16 character types of MBTI were : ESTJ 18.5%, ESFP 13.7%, ISTJ and ESFJ 9.7%. But INTP and INFP were low, 2.4% and 0.8%. 2. Average sizes of subjects for this study were : height 160.49cm, weight 51.83kg, bust 83.22cm, waist 65.49cm, hips 90.70cm. As compared with measurement of women at 20-24 age of Size Korea(2004), the subjects of this study showed less, about 0.2-5cm in height, 0.2-2cm in circumference except in waist, and 0.5-3.6cm in length. 3. After examining the relativity between personal measurement categories of the subjects and character type through the MBTI, Extraversion(E) type showed inverse correlation in stature, height, biacromial breadth, and subcutaneous fat thickness of posterior iliospinale. Contrary to the E type, the Introversion(I) type showed positive correlation. Sensing(S) type showed inverse correlation only in biacromial breadth, Intuition(N) type showed positive correlation in most categories including height, width and the subcutaneous fat thickness. Thinking(T) type showed positive correlation in bust point-bust point, chest depth and hip width. Feeling(F) type, on the other hand, showed inverse correlation. The Judging(J) type showed inverse correlation in stature, height, length and the parts of chest. In contrast, Perceiving(P) type showed positive correlation in other categories including biacromial breadth, same as the J type.

This study investigates the effects of information type, direction of information, method of suggestion, tie strength, and interactions among these variables on the acceptance and diffusion of fashion product information in the mobile Facebook environment. Two subsequent studies were conducted to test the relationships among mobile SNS WOM factors. Two independent on-line surveys were implemented. Six hundred forty consumers aged between 20 and 39 were recruited for Study 1, and four hundred and eighty for Study 2. We manipulated the WOM delivery situation by information type (factual/evaluative), information directionality (positive/negative), tie-strength (strong/weak), and information presentation method (text/image/rink). Eight scenarios were developed and randomly assigned to the research participants. Frequency analysis, reliability, factor analysis, regression analysis, and ANOVA were implemented using SPSS 18.0. The Analysis of experiment data produced interesting results. Most WOM factors (including the information type, information presentation method, and tie strength) influence WOM acceptance; however, only the tie strength effected WOM activity. It was also proven that people are prone to accept information that is more realistic, objective, and negative, and they tend to accept information with visual factors, such as images and video clips rather than a simple text message. In this study, we offer a practical perspective to fashion industry and marketers who have an interest in SNS marketing. We have defined the distinct characteristics of mobile WOM that have been formed by a combination of former on/off-line WOM characteristics. To examine the moderating roles of two types of consumer innovativeness, fashion innovativeness and technology innovativeness were also measured and found to have significant moderating effects between mobile SNS WOM factors and their consequences. The paper concludes with a discussion on managerial implications and limitations.

Purpose: The purpose of this study is to recognize the role and necessity of public data visualization through prior research, investigation, and data verification processes. In addition, this study intends to check what factors should be considered in order to visualize data on the mobile web. Through this process, by identifying the cognitive load affecting information visualization by type, as a result, I would like to propose an effective information visualization method to effectively deliver public data related to government policies. Research design, data and methodology: In this study, we analyzed the case of information visualization according to infographics, which has been widely used in the public field among various visualization methods. For this study, a questionnaire survey was conducted for young people in their 20s and 30s with the highest mobile usage rate. Results: Based on the results, IPA (Importance Performance Analysis) was performed to conduct cognitive load test tools for information visualization of public data and confirmed the implications for each type of infographics. Conclusions: As a result of research, in order to efficiently deliver public data on the mobile web, first, it is necessary to construct a visual screen that can be easily identified through clear data. Appropriate graphic elements can be used according to the type to make it easier for users to acquire and understand information. Second, it is necessary to provide useful content in visualizing information. Third, in order to efficiently transmit information and increase understanding of data, it is necessary to visualize information that can induce interest in data and form metaphors. Fourth, it is necessary to visualize information to reduce cognitive load in terms of physical and mental aspects in order to accommodate users' comfortable information. Fifth, in order to effectively deliver public data, it is necessary to compose contents and information that are easy for users to understand. This study examines effective information visualization methods to increase the communication effect of public data in response to changes in the data-based intelligent information society and suggests implications for each type considering cognitive loads to help future public institutions to communicate and accept information.

The purpose of this study was to identify the relationship between lifestyles and clothing purchasing behavior. The questionnaire was administered to 644 females aged 30∼40 in Taegu during April 21 to April 26 of 1997. Data was analyzed by frequency, percentage, mean, standard deviation, factor analysis, reliability test, MANOVA, and ANDVA by suing SPss package. 1. The lifestyles of the respondents were classified into fived types such as consumption oriented, economics-oriented, achievement-oriented, family-oriented, and conservative-oriented type. And clothing purchasing behavior was classified into six categories such as individuality, convenience, economy, ostentation, decorums, and practicality. 2. The results of lifestyle and clothing purchasing behavior analysis were as follows ; 1) All of five positive groups of consumption·economics·achievement·family and conservative-oriented type had an inclination for economy and individuality. And some differences were found according to the consumers, interest even in the same lifestyle. 2) The positive groups of consumption oriented type thought much of individuality and ostentation but on the other hand the passive group thought much of practicality. 3) The positive groups of consumption oriented, and family-oriented types except economics oriented and conservative oriented types took up a strong attitude toward ostentation, and ostentation was found in passive group of the conservative-oriented type. 4) The positive group of economics-oriented, achievement-oriented and conservative-oriented types except consumption-oriented and family-oriented types had great concern for practicality in the case of clothing purchasing behavior. But also the passive group of conservative-oriented types had an inclination for practicality. 5) Generally five types of lifestyles and clothing purchasing behavior showed that all types had the greatest concern for economy and individuality, and common for practicality and ostentation. And all of five types had partial concern for convenience and showed no differences for decorums.
