Vietnam has proceeded the gradual reform without radical political change since launching the 'Doi Moi', the comprehensive reform policy adopted in late 1986. Vietnam has been evaluated as a country to perform the economic growth for 30 years successfully, although there were economic recessions for a short time. Through looking at the process of reform, while the state economic sector and foreign-invested sector have contributed to the economic growth in the initial stage of reform, the domestic private sector and foreign-invested sector's economic roles have increased and the state sector's role has been decreased, as the reform has been proceeded. As the state's developmental role has been revealed prominently in the reform process and state's involvement into economic affairs in Vietnam, it is reasonable, in part, to categorize Vietnam as a developmental state like East Asian developmental states. However this evaluation is tentative, as it seems that Vietnamese state's industrial policies have contributed economic growth partly and remarkable economic growth has been shown in the sectors that the government has not focused. In conclusion, Vietnam has changed into a mixed country which has the characteristics of East Asian developmental state formally and the features of Southeast Asian countries which have focused more on the foreign-invested developmental strategy.

This paper investigates the causal impact of the increase in institutional distance between two geographic regions on the flow of cross-border Venture Capital (VC) between the regions. While cross-border VCs are believed to have competitive advantages at identifying and managing promising startups in a local market compared to local counterparts, the discrepancy in institutional characteristics between two markets exacerbates the difficulty of credible information exchange and negotiation, significantly increasing transaction cost related to a cross-border venture capital investment. This study conducts a difference-in-difference analysis to examine the relationship between institutional distance and the flow of cross-border VC investment using the fact that the official adoption of the Euro currency by member countries of the European Union except the UK created an institutional chasm between the UK and other EU member countries. The outcomes of the analysis suggests that UK-based VCs significantly decreased the VC investment into EU-based startups and that EU-based VCs reduced the investment into UK-based startups. The results have meaningful implications for understanding the impact of the change in institutional difference on cross-border VC investment, which seems to increasingly take place with the recent trend of de-globalization and the rise of protectionism.

The PhotoAcoustic Microscopy (PAM) has been proved to be a useful tool for biological and medical applications due to its high spatial and contrast resolution. PAM is based on transmission of laser pulses and reception of PA signals. Since the strength of PA signals is generally low, not only are high-performance optical and acoustic modules required, but high-performance electronics for imaging are also particularly needed for high-quality PAM imaging. Most PAM systems are implemented with a combination of several pieces of equipment commercially available to receive, amplify, enhance, and digitize PA signals. To this end, PAM systems are inevitably bulky and not optimal because general purpose equipment is used. This paper reports a PA signal receiving system recently developed to attain the capability of improved Signal to Noise Ratio (SNR) and Contrast to Noise Ratio (CNR) of PAM images; the main module of this system is a low noise, wideband signal receiver that consists of two low-noise amplifiers, two variable gain amplifiers, analog filters, an Analog to Digital Converter (ADC), and control logic. From phantom imaging experiments, it was found that the developed system can improve SNR by 6.7 dB and CNR by 3 dB, compared to a combination of several pieces of commercially available equipment.

This study investigates the impact of supply chain collaboration on performance in social economy in Korea. Collaboration is an effective method to overcome the disadvantages of newness and smallness of domestic social economy organizations. Nevertheless, most research on social economy examined conceptual relationship between collaboration and performance. Hence, this study focuses on empirically demonstrating the relationship between supply chain collaboration and performance in social economy. We identify two steps of supply chain collaboration structure, i.e., collaboration culture and collaboration implementation, and establish a research model to analyze the impact of collaboration of social economy organization on performance. Based on responses to a survey of 99 social economy organizations, we test the hypotheses in the theoretical model using PLS structural equation modeling. The result shows that both the effect of collaboration culture on collaboration implementation and the effect of collaboration implementation on performance are significant. This study contributes to the social economy literature by empirically investigating the impact of collaboration in social economy organizations on performance based on supply chain theories, and by expanding the application scope of supply chain theories to social economy organizations.

This paper explores the academic topography of the discourses on the anthropocene to delve into how the humanities can insightfully respond to the ecological crisis of the Earth through the lens of environmental humanities proposed in a 2020 book, The Anthropocene and the Humanities: From Climate Changes to a New Age of Sustainability by a scientific philosopher, Carolyn Merchant. By publishing her latest book, The Anthropocene and the Humanities, Merchant, a pioneering scholar of ecofeminism, has recently started into inquiring into the discourses on the anthropocene, meaning a geological age led by anthropos/humans. In one of her most distinguished works of 1980, The Death of Nature: Women, Ecology, and the Scientific Revolution, Merchant has revealed that the modern Western perception of nature, often identified with women, have been figuratively killing nature as well as women. Arguing in The Anthropocene and the Humanities that the anthropocene has been enacting a "second death of nature," which has been practically and technially killing nature, Merchant calls for the insight of the environmental humanities that help us to build a "sustainable livelihood" based on the "partnership" between human and nonhuman nature. This paper contemplates on what humanities can do in the era of anthropocenic planetarian crisis with the environmental humanistic alternatives in ecofeminist perspective to overcome the anthropocenic crisis aggravated by the covid-19 occurred at the point when the climate change was viscerally felt by the humans in the twenty first century.

This article aimed to looked back at the 1960s, which were assessed to be 'the age of essays', to survey denotations of essays, amplified by the discourse antagonism surrounding 'essays' and the writings of philosophers. Kim Hyeong Suk, Ahn Byeong Uk, and Kim Te Gil were philosophy professors of Yonsei University, Soongshil University, and Seoul National University and writers of numerous essay collections of the 1960s. However, there have been very few studies conducted on them. This is because of old prejudices within literary history that primarily undervalue essays and practices that try to limit them as 'Literariness'. Essays of the 1960s became the flavor of the times based on democratic demands that attempted to objectify individual experiences and grounds that passed through the war and the April 19 Revolution. The language of philosophers was expropriated through the various senses of first person writing to readers of the times, which lacked civil culture and national morality. Deficits in public spheres of the 1950s and 1960s were filled by Kim Hyeong Suk's narrations of comfort and conquest based on historic experiences, Ahn Byeong Uk's logic of self-discipline and knowledge based on democracy, and Kim Te Gil's humor and introspection that objectified the lives of the petit bourgeois. However, as the essays of philosophers failed to connect with the public discourse of the age, they were unable to go as far as sparking or serving as a medium for civil culture in the 1970s. Regardless, as essays rose historically in the 1960s, thought was given to the characteristics of the 'essay' genre and in connection, to the merits and demerits of cultural history that possesses the language of philosophers.

Quality is an important factor influencing organizational performance, so it should be possible to accurately and effectively measure the quality perceived by members. The Consumer Cooperative can be seen as a retail industry by industry classification, and there are various studies based on the dimension of retail quality, but compared to the general retail industry, few studies have been conducted based on the quality level perceived by members. The purpose of this study is to develop quality dimensions and sub-attributes by analyzing in detail and elaborately how the quality of cooperative is viewed from the perspective of members who are both consumers and owners. To this end, the quality dimension of cooperative quality is needed to be newly developed and quality components are demonstrated based on previous studies on the quality dimension. The quality dimension of the cooperative was developed through prior research to suit the value of the cooperative in product, service, and social responsibility, and a survey was conducted to demonstrate the four major cooperative members in Korea. Through this, sub-dimensions were constructed and the quality dimension of the high-order model was demonstrated through exploratory factor analysis and confirmatory factor analysis. It aims to discover key management elements in terms of quality management and provide practical implications to management.

In this paper, we propose speech enhancement algorithm as a pre-processing for robust speech recognition in noisy environments. Auxiliary-function-based Independent Vector Analysis (AuxIVA) is performed with weighted covariance matrix using time-varying variances with scaling factor from target masks representing time-frequency contributions of target speech. The mask estimates can be obtained using Neural Network (NN) pre-trained for speech extraction or diffuseness using Coherence-to-Diffuse power Ratio (CDR) to find the direct sounds component of a target speech. In addition, outputs for omni-directional noise are closely chained by sharing the time-varying variances similarly to independent subspace analysis or IVA. The speech extraction method based on AuxIVA is also performed in Independent Low-Rank Matrix Analysis (ILRMA) framework by extending the Non-negative Matrix Factorization (NMF) for noise outputs to Non-negative Tensor Factorization (NTF) to maintain the inter-channel dependency in noise output channels. Experimental results on the CHiME-4 datasets demonstrate the effectiveness of the presented algorithms.

In this paper, we present the Korean menu-ordering Sentence Text-to-Speech (TTS) system using conformer-based FastSpeech2. Conformer is the convolution-augmented transformer, which was originally proposed in Speech Recognition. Combining two different structures, the Conformer extracts better local and global features. It comprises two half Feed Forward module at the front and the end, sandwiching the Multi-Head Self-Attention module and Convolution module. We introduce the Conformer in Korean TTS, as we know it works well in Korean Speech Recognition. For comparison between transformer-based TTS model and Conformer-based one, we train FastSpeech2 and Conformer-based FastSpeech2. We collected a phoneme-balanced data set and used this for training our models. This corpus comprises not only general conversation, but also menu-ordering conversation consisting mainly of loanwords. This data set is the solution to the current Korean TTS model's degradation in loanwords. As a result of generating a synthesized sound using ParallelWave Gan, the Conformer-based FastSpeech2 achieved superior performance of MOS 4.04. We confirm that the model performance improved when the same structure was changed from transformer to Conformer in the Korean TTS.

The purpose of this study is to verify the practical validity of financial sanctions, which has recently emerged as the most powerful form of economic sanctions preferred by U.S. foreign policy tool. Based on the theoretical discussion, analyse this study the trend of de-dollarization appearing in connection with financial sanctions and argue that the effectiveness of financial sanctions erode the dollar financial hegemony, which is the source of its power can be degraded, so that its effectiveness could not be so great as most people likely think about. After World War II, there has been an increasing tendency in the international community to favor economic sanctions over the use of military force as an effective means of foreign policy. Among these economic sanctions, a distinct feature that has recently appeared is the remarkable increase in the frequency of use of financial sanctions. The country that favors financial sanctions most is the United States. The reason is that they believe that the power of their own dollar financial hegemony can exert deadly pressure on other countries. Financial sanctions favored by the United States are said to have increased the effectiveness of sanctions by upgrading the pressure of sanctions to the next level. Nevertheless, financial sanctions have a side that underestimates the cost. This problem is found in the signs that the backlash from not only countries subject to financial sanctions but also many countries with interests in these countries is leading to a tendency to de-dollarization. This study will try to see how likely this de-dollarization trend is to offset the effectiveness of financial sanctions.
