  • Objectives: Hyungsang medicine (HM) is an inspection which emphasizes the relationships between pathological patterns and one's facial or bodily shape, color and movement. The purpose of this study was to review previously published study results of the HM. Methods: The authors reviewed a total of 51 HM-related studies published from 2000 to 2012 found on PubMed and various domestic Oriental medicine journals. Each study was classified into theoretical, diagnostic, or treatment-related category. Results: Theoretical studies were mostly based on the Nei-Ching and Dong-Eui-Bo-Gam texts, and dealt with differences in form between types such as masculine and feminine, the five organ image types, the four-type categorization of body essence, vital energy (Qi), mentality, and Blood, Gallbladder and Bladder, the four-type categorization of fish, bird, horse, and turtle types, and the six meridian types. Research on diagnosis has been performed on diagnostic characteristics of HM, correlation between HM and general coordinative manipulation (GCM), and Hyungsang medicine and ante-disease pattern (未病類型). Studies on treatments could largely be classified as treatments for specific diseases using certain acupuncture or herbal prescriptions based on HM. Treatments were mostly evaluated solely through subjective symptom improvement of patients. Conclusions: Our review results suggest that HM-related studies were focused on the constitutional characteristics and clinical utility of HM. To strengthen the theoretical basis of HM and its clinical utility, clinical trials including randomized, treatment-placebo and blind methods are needed.

  • This paper is a theoretical inquiry of the changing roles of digital technologies in the representation of risk. Critically examining existing perspectives on risk society and risk communication, this paper argues that digital technologies and images in risk communication have been relatively understudied. Having said that, this paper suggests that Actor-network Theory provide useful theoretical tools for current studies on how digital technologies affect contemporary risk communication practices. Furthermore, this paper examines varied recent studies investigating how digital technologies of visualization are at play in risk communication practices. In doing so, this paper demonstrates how digital images and technologies interrupt the processes that scientific evidence is presented and facts are constructed in varied contemporary scientific reasoning. It will focus on the emerging mode of seeing and visual regime made possible by the increased usage of digital image and technologies, which are characterized by networked connection, sensor, computerized algorithm, and increased storage space. Finally this paper will discuss on the implications on future studies on the roles of digital images and technologies in risk communication practices in Korean context.

  • Such is an elective affinity between literary studies and psychoanalysis that the latter sometime serves as a form of literary pedagogy. The affinity mainly consists in their shared concern for language. The signification of language in psychoanalysis is much similar to that of literature. Many of psychoanalytic terms and theoretical tenets bear witness to its dependence clinically on speech phenomena and theoretically on language in general. It is most true of Sigmund Freud, for whom the unconscious is in effect the linguistic unconscious. The Freudian unconscious, compressing and displacing through images and ideas, works as a text for psychoanalysis, which approach has not only paved one of the ways to poststructuralist anti-essentialism but with which literary studies also feel uncanny familiarity. Freudian psychoanalysis, starting empirically from clinical observations, discovers that words exist independent of meanings in the form of things in the unconscious system. Out of the various sensory elements of a word-thing, in psychoanalytic terms, the auditory is central. Now with the auditory imagination cultivated in the clinic, Freud figures out compression and displacement as the chief unconscious works, of which my main argument is that they are based phonetically on heteronym and homonym associations respectively. Compression and displacement work to be masks, which excites Freud's sense of challenge: his is a kind of poststructuralist approach, in the sense that the closed interrelatedness of words without external referents determines the signification in a given situation. But the works of compression and displacement, viewed in auditory terms rather than mapped on to metaphor and metonymy, can provide a new insight for a literary reading of Freud. Pursuing Freud's auditory imagination is not only an attempt to read his writing as literary text rather than for theoretical discussion, but also an experiment with the possibility of literary reading of a theoretical text in the age of after-theory.

  • We review the literature on the effectiveness of capital controls and macroprudential measures. First, we explain the purposes and examples of capital controls and macroprudential policies. We then analyze various theoretical models and empirical findings from prior studies that investigate the effectiveness of each instrument. Moreover, we review several studies that directly compare the two instruments and discuss whether policymakers should implement capital controls or macroprudential measures to overcome financial crises. Finally, based on a discussion of the findings of previous studies, we suggest several possible avenues for future research.

  • Purpose: This review aimed to integrate the results of studies related to job embeddedness of clinical nurses and suggest directions for future research. Methods: A search for relevant studies was conducted using six databases according to the predetermined index terms "nurse" and "job embeddedness." A total of 28 studies that met the inclusion criteria were selected and analyzed. Results: The definition of job embeddedness was consistent in the articles, but the terms, scope, and use of tools to determine job embeddedness were not. In addition, no article suggested a theoretical framework. In all the studies except one, the tool used to measure job embeddedness was one revised from Mitchell et al. (2001). In 15 articles, a negative correlation was found between job turnover and turnover intention. Job embeddedness was also found to be associated with nurses' work environment, organizational citizenship behavior, and organizational commitment, and it had a positive impact on these variables. Conclusion: Job embeddedness can be used as a major variable to explain nurses's turnover intention. Job embeddedness is multidimensional, and a theoretical framework is needed to explain the job embeddedness of clinical nurses. Tools specific to Korea should be developed to measure the job embeddedness of Korean clinical nurses.

  • Housing Adjustment is a set of creative human activities that take place to meet various housing needs. Thus far, numerous studies have given attention to speculate a typology of those activities on an empirical base. Overall, though, little is known about its theoretical underpinning, due to the independent nature of each individual study in interpreting differences in conclusions. This study examines and compares results from two previous studies on housing adjustment. Previous research on housing adjustment suggests that, other than household and housing characteristics, housing satisfaction as an intervening variable is deeply associated with the choice of housing adjustment involved in mobility, home improvement, or cognitive adaptation. The two studies used similar theoretical schemes, asked similar questions, yet one sample consisted of Korean American residents and the other sample was poor housing residents in Korea. This study shows that differences in sample characteristics lead to a strong discrepancy in interpreting Speare's (1974) satisfaction theory of housing adjustment. For Korean Americans, housing satisfaction turned out to be a good predictor of housing adjustment preference, while it is not the case for poor housing residents in Korea. This implies that findings of any Single study can not be generalized directly to the population as a whole. Thus, continued effort should be made to compare specific findings from various research studies, seeking explanations for differences in conclusions. Theory can be legitimately built and strengthened in this integrated manner.

  • These days the interest of quality leads to the necessity of control charts for monitoring the process in various fields of practical applications. The $\overline{X}$ chart is one of the most widely used tools for quality control that also performs well under the normality of quality characteristics. However, quality characteristics tend to have nonnormal properties in real applications. Numerous recent studies have tried to find and explore the performance of $\overline{X}$ chart due to non-normality; however previous studies numerically examined the effects of non-normality and did not provide any theoretical justification. Moreover, numerical studies are restricted to specific type of distributions such as Burr or gamma distribution that are known to be flexible but can hardly replace other general distributions. In this paper, we approximate the false alarm rate(FAR) of the $\overline{X}$ chart using the Edgeworth expansion up to 1/n-order with the fourth cumulant. This allows us to examine the theoretical effects of nonnormality, as measured by the skewness and kurtosis, on $\overline{X}$ chart. In addition, we investigate the effect of skewness and kurtosis on $\overline{X}$ chart in numerical studies. We use a skewed-normal distribution with a skew parameter to comprehensively investigate the effect of skewness.

  • This paper contains results of the theoretical studies of the electrical breakdown properties in sulfur hexafluoride. Since the strong interaction of high-energy electrons with the polyatomic sulfur hexafluoride molecule causes their rapid deceleration to the lower energy of electron capture and dissociative attachment, the breakdown is only possible at relatively high field strengths. From the breakdown voltage curves, the effective yields that characterize secondary electron productions have been estimated. Values of the effective yields are found to be more consistent if they are derived from the experimentally determined values of the ionization coefficient and the breakdown voltages. In addition, simulations were performed using an one-dimensional Particle-in-cell/Monte Carlo collision code. The obtained simulation results agree well with the available experimental data with an error margin of less than 10% over a wide range of pressures and the gap sizes. The differences between measurements and calculations can be attributed to the differences between simulation and experimental conditions. Simulation results are also compared with the theoretical predictions obtained by using expression that describes linear dependence of the breakdown voltage in sulfur hexafluoride on the pressure and the gap size product.

  • Analytical studies were conducted to develop the Spectral-Analysis-of-Surface-Waves (SASW) method for underwater use. For the precise estimation of the in-situ soil stiffness profile from SASW measurements, it is essential to determine economical and reasonable theoretical dispersion curves reflecting various experimental conditions. In this paper, therefore, analytical methods are mainly discussed, which were developed to determine theoretical dispersion curves of surface waves propagated along the soil-water interface. Application of the analytical methods is then illustrated by an example involving estimation of a stiffness profile through a forward modeling process of SASW measurements. Applicabilities of the SASW method as well as the developed analytical methods are evaluated, respectively, from the example.

  • The role of interaction in second language (L2) classrooms has been examined from different angles, ranging from early studies of foreigner talk to the studies of the teacher- and task-based talk. However, most of the research on L2 classroom interaction has been based on a traditional psycholinguistic view of language and learning, failing to reconceptualize a broad and holistic understanding of L2 learning. Currently, many researchers have attempted to explore and describe classroom interaction in L2 classrooms from a sociocultural perspective. The purpose of this paper is to discuss Vygotsky's theoretical framework in terms of L2 classroom interaction and research from a sociocultural perspective, by describing three key concepts (zone of proximal development, private speech, and activity theory) in Vygotsky's theoretical framework and relating them to L2 classroom interaction. The results demonstrated the importance of social interaction for second language acquisition with the review of the related research study. It was also suggested that the dynamic and interactive processes of second language learning in the classroom should be valued by L2 researchers as well as L2 teachers. Finally, implications for the concepts for L2 classroom research and pedagogy are presented in the conclusion.
