From the perspective of corporate governance, we examine the acquirers' performance of mergers and acquisitions. The empirical results of our study show that outside active shareholders, such as block shareholders or institutional shareholders, affect acquirers' performance in M&A's : the ownership of outside active shareholders is positively correlated with the performance of acquirers. However, the ownership of insiders, such as that of encumbent manners or major shareholders, does not have any significant effect on the performance of M&A's. We also found that the ownership of foreign investors increased its explanatory power after the financial crisis of Asia. Since the current literature concludes that the improvement of corporate governance would enhance the shareholders' wealth, the results of our study implies that outside active investors, rather than insiders, are playing an important role in the corporate governance.

The concept of the sharing economy, which has shifted the economic paradigm from possession to access to resources, is consistent with the traditional and current roles of public libraries. Thus, this research empirically analyzed the influence relationships between public library use and the sharing economy. Results showed that participation in public library programs serves as a motivational factor for satisfaction with and trust in the sharing economy, while the use of public library facilities and equipment is correlated with attitudes toward and participation in the sharing economy. The use of library collections positively influences sharing intangible resources such as knowledge, information, and personal experience. By contrast, checking out library resources negatively influences the recognition of economic benefits from sharing, which is contrary to claims of library communities. Based on these results, public libraries should aim to have a complementary effect on the sharing economy founded not only on information networks but also human networks grounded in social relationships.

As the consumption paradigm shifts from 'possession' to 'subscription', the subscription economy market is growing rapidly. The subscription economy is characterized by the fact that consumers can pay for and purchase products and services and use them limitedly for a limited time. Therefore, this study examined the effect of subjective perception of the time (duration) of consumers' subscription service use on subscription intention according to the time presentation method (duration/date) of subscription service use. In addition, the effect of differences in time presentation methods according to the type of subscription service (utility/hedonic) on subscription intention was examined. As a result of the study, the willingness to subscribe was higher when offering by date than when offering by date. In addition, for subscription services consumed for practical purposes, there was no difference in the effect on subscription intention according to the time presentation method. appeared to be Based on these results, the theoretical significance and practical implications of this study were presented.

최근 도시화 및 불투수면의 증가와 지하수의 과다한 사용으로 직접유출이 증가하고, 침투량이 감소하며, 하천의 건천화가 발생하고 있다. 이에 환경부에서는 이러한 물순환의 왜곡을 막기위해 물환경보전법상의 물순환율을 정의하고 물순환 관리목표를 설정하였다. 하지만 지역 별 물순환 특성을 반영한 관리계획이 부족하고, 현재 제한된 재원의 효율적 활용을 위해서는 물순환 관리지역에 대한 우선순위 결정도 필요하다. 본 연구에서는 PSR framework를 통해 유역 물순환 평가방법론을 만들고 이를 활용한 지역별 관리계획 및 우선순위를 결정하고자하였다. PSR framework는 지속가능성을 위해 OECD가 개발한 개념 모형이며, Pressure, State, Response 세 가지 요소로 구분해 평가하게된다. PSR framework의 기본 개념은 인간의 활동들이 환경에 압력 (P)를 주고, 이로 인해 자연의 질과 영향 (S)을 미치며, 이에대한 회복을 위해 인식과 행동을 통해 정책과 제도 등을 통해 반응 (R)한다는 것이다. 유역 물순환을 4가지 그룹 (기후, 수문학적, 사회경제학적, 환경적)으로 구분하고 각 그룹 별 평가요소에 대하여 도출하였다. 기후그룹은 강우, 수문학적 그룹은 증발산, 토지이용, 유출특성을, 사회경제학적 그룹은 재정, 사회구조, 기반시설, 정책을, 환경적 그룹은 수질, 수생태계를 선정하였다. 이후 각 요소 별 평가를 위해 다양한 지표를 고려하여 선정하였으며, 각 지표를 PSR framework에 맞춰 재분류하였다. 각 지표를 하나의 점수로 통합하기 위해 지표 별 가중치를 산정하였으며, 이때 연구자의 주관이 반영되지않는 엔트로피 기법을 이용하여 산정하였다. 구한 식을 통해 우리나라 소유역구분을 기준으로 모든 지표를 계산하였으며, 각 지표에 가중치를 적용해 유역 종합점수를 산정하고 유역 별 취약지역 및 취약요소를 평가하였다.

Deep Learning is a useful method for classifying and recognizing complex data such as images and text, and the accuracy of the deep learning method is the basis for making artificial intelligence-based services on the Internet useful. However, the vast amount of user da vita used for training in deep learning has led to privacy violation problems, and it is worried that companies that have collected personal and sensitive data of users, such as photographs and voices, own the data indefinitely. Users cannot delete their data and cannot limit the purpose of use. For example, data owners such as medical institutions that want to apply deep learning technology to patients' medical records cannot share patient data because of privacy and confidentiality issues, making it difficult to benefit from deep learning technology. In this paper, we have designed a privacy preservation technique-applied deep learning technique that allows multiple workers to use a neural network model jointly, without sharing input datasets, in multi-party system. We proposed a method that can selectively share small subsets using an optimization algorithm based on modified stochastic gradient descent, confirming that it could facilitate training with increased learning accuracy while protecting private information.

In light of the COVID-19 incident, organizations have recognized the importance of systematically managing knowledge resources to enhance work efficiency and performance within the organization. We have adopted the perspective of knowledge hoarding, which entails the ownership of individual knowledge, and aim to elucidate the underlying mechanisms that contribute to knowledge hoarding by considering the organizational environment, personal characteristics, and task characteristics. To test our hypothesis, we conducted a survey among employees working in companies that have implemented knowledge management policies or systems. We obtained a total of 381 samples, which were analyzed using AMOS 22.0 and Process 3.1 macros. Our findings reveal that distributive injustice leads to conflicts relationships and subsequently increases individual knowledge hoarding. Furthermore, we found that sensitivity to incentive interacts with distributive injustice, further exacerbating knowledge hoarding. Conversely, task interdependence mitigates knowledge hoarding by interacting with distributive injustice and relation conflict. These results contribute to the development of effective organizational knowledge management strategies aimed at curbing knowledge hoarding within the organization.

Toponyms are located not only in the site between human cognition and the physical environment but also in the name of cultural heritage. Accordingly, certain identities and ideologies for which human groups and community have sought, their holistic way of life, and all cultural symbols and cosmos, such as sense of place and genius loci, are included in their toponymic heritage. Denoting, symbolizing, integrating and representing the culture and nature belong to the human community. Based on these perceptions of the toponymic heritage, the aims of this article are to examine the values of a toponym as an Intangible Cultural Heritage (ICH) and to suggest the application methods using the toponymic functions for governing of tangible cultural heritage. This article discusses the multivocality, diversity, and non-representational theory of landscape phenomenology intrinsic to the terms of culture and cultural landscape and then the domestic and international issues on the toponymic heritage in the first chapter on the values of toponym as a part of the ICH. In particular, it analyzes the preceding research in the field of toponymy, as well as the Resolutions of UNCSGN and UNGEGN on "Geographical names as culture, heritage and identity" including indigenous, minority and regional language names since 1992, which is related to the UNESCO's Convention for the Safeguarding of the Intangible Cultural Heritage in 2003. Based on this, I suggest that the traits of toponymic cultural heritage and its five standards of selection, i.e., cultural traits of toponyms, historical traits, spatial traits, socio-economic traits and linguistic traits with some examples. In the second chapter discussing on the methods using the toponymic denoting functions for creating and governing of the tangible cultural heritage, it is underlined to maintain the systematic and unified principle regarding the ways of naming in the official cultural heritage and its governing. Lastly, I introduce the possible ways of establishing a conservative area of the historical and cultural environment while using the toponymic scale and multi-toponymic territory. Considering both the spatial and participatory turns in the field of heritage studies in addition to the multiple viewpoints and sense of cultural heritage, I suggest that the conservative area for the cultural heritage and the historical and cultural environment should be set up through choosing the certain toponymic scale and multi-toponymic territory.

The purpose of this study is to investigated and differences per lifestyle type according to characteristics of participation in eco-tourism by classifying lifestyle types of university student consumers. Also, the influences exerted on characteristics of participation in eco-tourism by the variables of demographical characteristics, lifestyle types and characteristics of eco-tourism were analyzed. The results indicated by the research can be summarized as follows. First, significant differences were found in terms of sociability inclination factors and leisure inclination factors. In other words, the group of people who had participated in eco-tourism were more of sociability-inclined and leisure-inclined lifestyle types than the group of people who had not participated in eco-tourism. Second, logistic analysis on the types of influences exerted on participation in eco-tourism by demographical characteristics, characteristics of eco-tourism and lifestyle types, it was found that significant influences were exerted by such variables of propensity of learning in eco-tourism, leisure inclination factors and school year. Third, regression analysis on the types of influences exerted on intention to participate in eco-tourism by demographical characteristics, characteristics of eco-tourism and lifestyle types, propensity of awareness on eco-tourism, tendency of preferring eco-tourism, sociability inclination factors and progress inclination factors were selected as significant variables.

The purpose of this study is to consider the appearance of the global generation transnational identity and forming process, existence aspect, functional role, and on the actuating mechanism, and etc. The results about the transnational identity of Diaspora and diversity are as follows. First, as to the transnational identity, the emigrants had been being determined by the relation with the accreditation and how type had been deal with one's decision about the self-identify. Second, the individual experience of the emigrant, interaction, and unstable status political support etc. various factors were combined and the diversity of the Diaspora identity showed. Third, the identity concept had been performing the function in the more expanded meaning called the nation and nation through the continuous meaning expansion than the individual as the national ideology. Fourth, the transnational identity of Korean-Chinese was specialized into the nation identity, double identity, and 'the identity of the third' etc. Fifth, the transnational identity of the Nikkei-Brazilian appeared for Japanese identity, Brazilian identity, and Nikkeijin identity etc. in Japan. In conclusion, the Transnational identity of the Diaspora is reproducing the identity of the emigrant, it suggests through the differentiation in the settlement and exclusion.
