  • This paper investigates the consumer arbitration practices In the U.S. The key issue in consumer arbitration is how to protect the individual consumers from the loss of their legal rights stemming from the arbitration agreement with the business. In the U.S., the major legal doctrines to protect individual consumer include the voluntary-knowing-intelligent doctrine, unconscionability doctrine, and void contract. Even though the US courts are favorable to the enforceability of arbitration agreement, they strictly apply the contract law theories in deciding the existence of arbitration agreement, providing a strong common law protection for the consumers in arbitration. However, the practices for protection of consumers in arbitration in Korea are not mature yet. If consumer arbitration is widely adopted into B to C contracts, a protective measure for individual consumer can be found in the Act of Clause Regulation providing that the business has duty to explain the relevant clause in the adhesive contracts.

  • On the hyperbolic space $D^n$, codimension-one totally geodesic foliations of class $C^k$ are classified. Except for the unique parabolic homogeneous foliation, the set of all such foliations is in one-one correspondence (up to isometry) with the set of all functions z : [0, $\pi$] $\rightarrow$ $S^{n-1}$ of class $C^{k-1}$ with z(0) = $e_1$ = z($\pi$) satisfying |z'(r)| ${\leq}1$ for all r, modulo an isometric action by O(n-1) ${\times}\mathbb{R}{\times}\mathbb{Z}_2$. Since 1-dimensional metric foliations on $D^n$ are always either homogeneous or flat (that is, their orthogonal distributions are integrable), this classifies all 1-dimensional metric foliations as well. Equations of leaves for a non-trivial family of metric foliations on $D^2$ (called "fifth-line") are found.

  • John Harer conjectured that the canonical map from braid group to mapping class group induces zero homology homomorphism. To prove the conjecture it suffices to show that this map preserves the first Araki-Kudo-Dyer-Lashof operation. To get information on this homology operation we need to investigate the image of braiding under the Harer map. The main result of this paper is to give both algebraic and geometric interpretations of the image of braiding under the Harer map. For this we need to calculate long chains of consecutive actions of Dehn twists on the fundamental group of surface.

  • The purpose of this study is (1) to develop the teaching plan based on Practical Problems solving on the area of food habits in home economics class and (2) to investigate the participation of teaching, the attitude of teaching method and food life. The subject of this study was two classes consisted off 66 students(male 26. female 40, 33 for each class) who are the first grade of middle school. The comparison group was taught by lecturing. while the experiment group by cooperative learning. The period of this experiment was three weeks: from June 7th to Jun 23th. 1999. The experiment was conducted through 5 classes. First of all students identify the problem of food habits and seek and evaluate information. Students evaluate actions and reflect on decision and evaluate action. The statistical method for the study was a paired T-test. The results of this study are as follows: 1. After experiment, the participation of teaching(p<.05) and the attitude of teaching method(p<.01) in the experiment group showed a statistically significant difference. Therefore the students in the class based on the practical problems solving took an active part in teaching 2. The practical problems solving is more effective than the lecturing in doing guide the positive attitude of teaching. 3. Through the experiment the attitude of food life in the experiment group showed a statistically significant difference(p<.05) Therefore the practical problems solving is more effective than the lecturing in changing positive attitude of food life.

  • This paper studied tangible interaction design of VR platform and its applications that are economic In development process and cost, flexible by contents and installation conditions, and that has business potential for consumer market. The design solution uses video based virtual world and tangible interaction by motion tracking. Our platform enables a user to monitor their action and to collaborate with other users of remote place within attractive interaction feedback. We developed two design applications, Glass Xylophone 2003 and VR Class, in our platform. Glass Xylophone 2003 provides interactive music performance and helps self practice of glass xylophone. VR Class gives more serious distance learning experience with tutoring and group collaboration. They are presented in public exhibitions and tested by exhibition visitors. They showed application potential of this design solution in interactive game, distance learning, and entertainment field.

  • Metformin is widely used for T2D therapy but its cellular mechanism of action is undefined. Recent studies on the mechanism of metformin in T2D have demonstrated involvement of the immune system. Current immunotherapies focus on the potential of immunomodulatory strategies for the treatment of T2D. In this study, we examined the effects of metformin on the antigen-presenting function of antigen-presenting cells (APCs). Metformin decreased both MHC class I and class II-restricted presentation of OVA and suppressed the expression of both MHC molecules and co-stimulatory factors such as CD54, CD80, and CD86 in DCs, but did not affect the phagocytic activity toward exogenous OVA. The class II-restricted OVA presentation-regulating activity of metformin was also confirmed using mice that had been injected with metformin followed by soluble OVA. These results provide an understanding of the mechanisms of the T cell response-regulating activity of metformin through the inhibition of MHC-restricted antigen presentation in relation to its actions on APCs.

  • The purpose of this study is to develop the Clinical Kinesiology Class Contents(: CKCC) by utilizing movies and investigate the effects of its application to clinical kinesiology learning. The developed CKCC were applied to the clinical kinesiology classes for 47 second year student of physical therapy and occupational therapy in K college in G City. CKCC includ movie scenes that can demonstrate the action of muscles effectively, for better student understanding, as has already been shown widely. The interest and understanding of CKCC by the class was analysed. The results show that the developed CKCC is very effective implement for stimulating students' interest(p<0.05) and understanding(p<0.05) of clinical kinesiology classes.

  • This paper aims to examine distribution and patterns of Women(我們) on Chinese conversation textbook, and also suggest that Chinese class need to impose pragmatic perspective. For this purpose, this paper explores 35 Womens in 42 conversation units on three Chinese textbooks Hanyu Kouyu vol.1~3 at first. Women is more contributed on 'exclusive Women' among three categories (inclusive, exclusive, borrowed) than other two categories, is also contributed on 'symbolic usage' than 'gestural usage'. Second, this paper examines patterns of Women on the three categories. It shows: first, 'inclusive Women', 'exclusive Women', 'borrowed Women' all show up on the textbooks even though on the textbook vol.1(for beginner) surprisingly; Second, 'exclusive Women' may be a primary one of three categories in terms of the coverage of Women. Women covers those who are related with the speaker regardless of being on the spot, and also covers those which the speaker belongs to, for example, nationality, ethnicity etc. Consequently, the results show that Chinese speaking course, from now on, needs to consider pragmatic factors including existing semantic and syntactic factors, and from the pragmatic perspective, impose 'action'(including speech act, body gesture etc.) on Chinese conversation class for the learners' improvement in Chinese speaking.

  • J.Milnor[Mi2] has introduced the notion of directional entropy in his study of Cellular Automata. Cellular Automaton map can be considered as a continuous map from a space $K^Z^n$ to itself which commute with the translation of the lattice $Z^n$. Since the space $K^Z^n$ is compact, map S is uniformly continuous. Hence S is a block map(a finite code)[He]. (S is said to have a finite memory.) In the case of n = 1, we have a shift map, T on $K^Z$, and a block map S and they together generate a $Z^2$ action.
