  • This study aims to describe the vowel system of present-day American English and to discuss some of its phonetic variations due to regional differences. Fifteen speakers of American English from various regions of the United States produced the monophthongs of English. The vowel duration and the frequencies of the first and the second formant were measured. The results indicate that the distinction between the vowels [c] and [a] has been merged in most parts of the U.S. except in some speakers from eastern and southeastern parts of the U.S., resulting in the general loss of phonemic distinction between the vowels. The phonemic merger of the two vowels can be interpreted as the result of the relatively small functional load of the [c]-[a] contrast, and the smaller back vowel space in comparison to the front vowel space. The study also shows that the F2 frequencies of the high back vowel [u] were extremely high in most of the speakers from the eastern region of the U.S., resulting in the overall reduction of their acoustic space for high vowels. From the viewpoint of the Adaptive Dispersion Theory proposed by Liljencrants & Lindblom (1972) and Lindblom (1986), the high back vowel [u] appeared to have been fronted in order to satisfy the economy of articulatory gesture to some extent without blurring any contrast between [i] and [u] in the high vowel region.

  • The purpose of this study is to analyze the moderating effect of health privacy information on the relationship between the factors that affect the behavioral intention of the usage of u-health system have. Therefore, as a research hypothesis in TRA (Theory of Reasoned Action), self-efficacy and perceived usefulness will have a positive effect on the behavioral intention of the u-health system, and in the path, that personal information factors have an effect on each path. This study used the PLS-SEM methodology to verify the proposed research model. As a result of the analysis, this study showed that the moderating effect of health personal information in the presented model affects to some extent by the increase of R2 explanatory power. However, it was found that it was more consistent with the role of the independent variable rather than the moderating influence on the perceived usefulness.

  • Interest on ocean environment has increased with the development of industrialized activities. Public marine resorces are defined broadly to include fish stocks, beaches, marine waters, recreational fishing, biota, waterfowls, shorebirds, seabirds and marine mammals But, it is not easy to analyze compensation for injury to publicly owned marine resources because the claimants do not exist clearly and the economic methodology of damage on public goods is not developed fully. This paper introduces basic idea of welfare economic theory and environmental legislation to the research question : How the economics and law can be applied to the case of damage on publicly owned marine resource. The paper discusses the concepts of willingness to pay (WTP) and willingness to accept (WTA). It is accepted generally that WTA is correct concept of welfare change in the case of damaged public goods. Four methods (compensating variation, equivalent variation, compensating surplus, equivalent surplus of measuring welfare changes are compared. Compensating variation(CV) is the best measure of welfare changes are compared. Compensating variation(CV) is the best measure of welfare changes caused by environmental damage. Vartia (1983) showed CV could be measured from the ordinary demand function using the differential equations. This paper also provides an overview of the emerging U.S. and Korea legal system for compensation for natural resource damages, with particular emphasis on U.S. legal system under Comprehensive Environmen-tal Response Compensation and Liability Act (CERCLA). These regulations are to include two different types of standardized procedures for assessing natural resources injury : Type A or simplified assessment techniques for small releases ; and Type B protocols that would include detailed and extensive assessment methodologies for major releases. Type A procedures are specified by Natural Resources Damage Assessment Model for Coastal and Marine Environment (NRDAM/CME) of the U.S. CERCLA provides a legal 'legitimization for the use of economic-based nonmarket valuation in the courts and have introduced appropriate and accurate nonmarket valuation methods based on willingness to-pay for damage assessment. By briefly reviewing economic theory and environmental legislation, we hope to help provide a better understanding of the compensation process and the economics of publicly owned marine resources in the U.S. and to integrate the economics and law of natural resources valuation into a single comprehensive package in Korea.

  • In western, aromatherapy uses essential oils to prevent and treat disease, and is one of the ways to stay healthy. In oriental medicine, there was also a similar medical treatment using aromatic herbs for a long ago. The exisiting research of oriental medical herbs is mainly focused on the theory of qi and flavor(氣味論). But on aromatherapy used with aromatic herbs, it is necessary to study the aromatic herbs by aroma. So "xi$\bar{a}$ng p$\check{u}$, 香譜" and "b$\check{e}$n c$\check{a}$o g$\bar{a}$ng m$\grave{u}$, 本草綱目" mainly contain the study about clinical effects of aromatic herbs. And "b$\check{e}$n c$\check{a}$o p$\check{i}$n hu$\grave{i}$ j$\bar{i}$ng y$\grave{a}$o, 本草品彙精要"mainly explains the effects of medical herbs with five aroma classification of x$\bar{i}$ng(腥), sh$\bar{a}$n(膻), xi$\bar{a}$ng(香), ch$\grave{o}$u(臭), xi$\check{u}$(朽). The former one makes more clinical uses of medical herbs, and the latter one grows up the theory of medical herbs. This study is expected to have a good influence on aromatherapy and classification of oriental medical herbs.

  • In this study, the variation in excess pore pressure during dissipation is estimated by using successive cavity expansion theory and finite difference technique based on axisymmetric uncoupled linear consolidation theory with separate consideration of magnitude and initial distribution $\Delta{u}_{oct}$induced by changes of octahedral normal stress, and $\Delta{u}_{shear}$ induced by changes of octahedral shear stress. The coefficient of consolidation is also estimated by trial and error procedure until the predicted dissipation curve matches the measured curve at a typical degree of dissipation. The proposed method is applied to the results of miniature piezocone tests at Louisiana State University calibration chamber system. Based on the results of interpretation and the comparison with experimental measurements and those from other solutions, the prediction dissipation curves show a good match with those measured during dissipation tests and the values of coefficient of consolidation estimated by proposed method are more close to the range of laboratory measurements than those of other theories.

  • In 1976, the Dalkon Shield-intrauterine device injured several thousand women in U.S.A. which caused the changes of medical deivce regulation. The Medical Device Regulation Act or Medical Device Amendments of 1976 (MDA) was introduce. As part of the process of regulating medical devices, the MDA divides medical devices into three categories. The class II, and III devices which have moderate harm or more can use the section 510 (k), premarket notification process if the manufacturer can establish that its device is "substantially equivalent" to a device that was marketed before 1976. In 21 U.S.C. ${\S}$ 360k(a), MDA introduced a provision which expressly preempts competing state laws or regulations. After that, the judicial debates had began over the proper interpretation and application of Section 360(k) In February 2008, the U.S. Supreme Court ruled in Riegel v. Medtronic that manufacturer approved by the Food and Drug Administration (FDA)'s pre-market approval process are preempted from liability, even when the devices have defective design or lack of labeling. But the Supreme Court ruled in Medtronic Inc. v. Lora Lohr that the manufactures which use the section 510 (k) process cannot be preempted and in Bausch v. Stryker Corp. that manufactures which violated the CGMP standard are also liable to the damage of patient at the state courts. In 2009, the Supreme Court ruled in Wyeth v. Levine that patients harmed by prescription drugs can claim damages in state courts. This may cause a double standard between prescription drugs and medical devices. FDA Preemption is the legal theory in the United States that exempts product manufacturers from tort claims regarding Food and Drug Administration approved products. FDA Preemption has been a highly contentious issue. In general, consumer groups are against it while the FDA and pharmaceutical manufacturers are in favor of it. This issues also influences the theory of product liability of U.S.A. Complete immunity preemption is an issue need to be more declared.

  • Since the U.S. government officially accepted North Korean(NK) as refugees starting in 2006, about 120 North Koreans have come to and been living in the United States. However, little is known in regard to what the North Korean refugees need for a qualify life. This study aims to explore the essential experiences of North Korean defectors who have settled in the United States after escaping North Korea. Research inquiries are why North Korean refugees have chosen the United States for their settlement, and how they are living in the United States. Data were collected from in-depth interviews with eight NK refugees. For data analysis, grounded theory approach by Strauss and Corbin(1998) was employed. The data analysis identified the central phenomenon, protective and risk factors, and core actions and consequences of NK refugees' adjustment in the U.S. The central phenomenon was "voluntary choose to come to the U.S." The core action and consequences in the process of their adjustment were 'searching for the meaning of life,' and 'achieving acculturation.' The findings may provide deeper understanding on the situation of North Korean refugees in the U.S. and implications for how to help them adjust well in the society.

  • This paper deals with the behavior of positive solutions to the following nonlocal polytropic filtration system $$\{u_t=(\mid(u^{m_1})_x{\mid}^{{p_1}^{-1}}(u^{m_1})_x)_x+u^{l_{11}}{{\int_0}^a}v^{l_{12}}({\xi},t)d{\xi},\;(x,t)\;in\;[0,a]{\times}(0,T),\\{v_t=(\mid(v^{m_2})_x{\mid}^{{p_2}^{-1}}(v^{m_2})_x)_x+v^{l_{22}}{{\int_0}^a}u^{l_{21}}({\xi},t)d{\xi},\;(x,t)\;in\;[0,a]{\times}(0,T)}$$ with nonlinear boundary conditions $u_x{\mid}{_{x=0}}=0$, $u_x{\mid}{_{x=a}}=u^{q_{11}}u^{q_{12}}{\mid}{_{x=a}}$, $v_x{\mid}{_{x=0}}=0$, $v_x|{_{x=a}}=u^{q21}v^{q22}|{_{x=a}}$ and the initial data ($u_0$, $v_0$), where $m_1$, $m_2{\geq}1$, $p_1$, $p_2$ > 1, $l_{11}$, $l_{12}$, $l_{21}$, $l_{22}$, $q_{11}$, $q_{12}$, $q_{21}$, $q_{22}$ > 0. Under appropriate hypotheses, the authors establish local theory of the solutions by a regularization method and prove that the solution either exists globally or blows up in finite time by using a comparison principle.

  • Arbitration is contractual by nature. One cannot be required to submit to arbitration any dispute which he has not agreed to so submit. As commercial transactions become increasingly complex, involving multiple parties and numerous contracts for a single transaction, however, limiting the parties who are subject to arbitration to only those who have signed a contract containing an arbitration clause would frustrate the purpose of such arbitration clause and might lead to injustice among the relevant parties. Therefore, U.S. courts have recognized a number of theories under which non-signatories may be bound to the arbitration agreement of others: (1) incorporation by reference; (2) assumption; (3) agency; (4) veil-piercing/alter ego; and (5) estoppel. Incorporation by reference and veil-piercing theories have already been recognized by Korean courts. Agency theory and estoppel theory are not recognizable under Korean law. However, the same or similar result may be achieved by applying the third party beneficiary theory or assumption by third party theory. Although a couple of Supreme Court cases appear to be at odds with the assumption theory, on the basis of the recent amendments to the Arbitration Act, such court precedents can be and should be reversed.

  • Human resource theories of becoming entrepreneurs or self-employed rather than finding employment are compared as applied to fit the occupational data of technological entrepreneurs and technology jobs. The human capital theory posits that technological entrepreneurs are prepared to become a jack-of-all-trades with a variety of fields of education. Hobo theory of entrepreneurship assumes that entrepreneurs have strong taste against concentrating on a few activities, which tend to drive entrepreneurs away from employed jobs depressing their expected income. Another theory assumes that entrepreneurs have some unobserved productive qualities and abilities over employed people. Immigrant entrepreneurs could presumably be pressured out of employment under racial discrimination. Since technology jobs are mostly filled by those educated in the science and technology fields, and they presumably offer great reward to professional concentration, technological entrepreneurs may not benefit from becoming jacks-of-all-trades compared to finding employment in technological jobs income-wise. Asian immigrants in the 2000 US Census data are compared to white immigrants in technological jobs to test alternative human resource theories of entrepreneurship. Using English language ability as a proxy for the variety of education, I find in the white immigrant technological entrepreneurs support for the jack-of-all-trades theory, while in the Asian immigrant technological entrepreneurs hobo theory is supported. In the Asian technological workers only there appears the significant self-selection or comparative advantage component, while at the same time discriminatory components are significant.
