The organizational ambidexterity has been emerging as the way to gain competitive advantage in turbulent environment. The concept of ambidexterity is simultaneously accomplishing the balance between the activities of exploration and exploitation, and overcoming their conflicting tension. The beneficial merits of ambidexterity has been investigated in innovation, financial performance, strategic management, and etc. Our study focused on the impact of ambidextrous activities on creative performance. Although three ambidextrous modes-structural ambidexterity, contextual ambidexterity, and sequential ambidexterity-have been already acknowledged, scant studies suggested the specific mechanisms to achieve ambidexterity in practice at the operating level. To address the issue we performed the semantic network analysis on the basis of the previous literatures prescribing ambidexterity theory. We took interview with 21 teams to explore behaviors of teams from the ambidextrous perspective, and then interpreted the relationship among words which appeared in the interview. This study found the appropriate mechanism which alleviate tension revealed by exploitation and exploration exist as practical reality. We demonstrated how these ambidextrous mechanisms can be used to generate the creative performance as well as examined various antecedents. These findings would contribute to the more fine-grained understanding of organizational ambidexterity, especially in conjunction with organizational creativity.

Amongst society's transitional presuppositions towards the future, population aging is the most critical issue in Korea. Immediate attention to devise a countermove is required. One of the major trends appeared in retirement communities of advanced countries is social integration which has been considered as a promising future direction of elderly housing development. This study aims to find out social integration characteristics and to categorize local engagement types of recent retirement communities through the characteristics of sharing common facilities and programs. Data were collected through mainly web site and literature reviews. Contentent analysis technique was used. Ten CCRC cases were selected through web search using the major key words such as 'intergenerational'. As a result, community engagement types were classified into six categories by the degree of sharing both physical and program resources between the retirement community and local area. This type can be utilized to develop alternative housing and retirement community for the older adults as a new model which activates the resident and vitalizes the retirement community through local engagement by physical and social resources.

The Covid 19 pandemic officially broke out in Jan 2020 and ended in Mar.2023, following the WHO, claiming 7 million lives. For the three years, while the world made concerted effort to fight against the deadly virus, South Korea was praised as a model country in that the country effectively contained the spread of the virus. Given this, the paper aims to figure out how South Korea's story was quoted by looking at six editorials in the New York Times and the Washington Post. For this aim, we have analyzed linguistic expressions within White (2003)'s appraisal theory and then conducted a key word frequency analysis. The analysis results as follows: first South Korea's story was quoted to criticize the U.S. government of its wrong management to the Covid-19, also giving some lessons to the world; second, both newspapers attribute the South Korea's success to its swift and rapid response to the pandemic; and third, the Washington Post showed more positive attitude to South Korea than the New York Times by quoting the country's success more frequently with more positive words in evaluating the country's responses to the pandemic while both newspapers showed negative attitudes to the U.S. government to the issue. Thus, it can be concluded that linguistic expressions in quotations are effectively used in showing the newspapers' attitude toward South Korea and the U.S.

This study aimed to express the experiences of the parents who lost their children by suicides in their own words from their own perspectives by van Manen(2000)'s hermeneutic phenomenological approach. The analysis of the words expressed by the research participants led to the following five fundamental themes. These are 'broken heart, sinner's grief, land of exile and time stood still, pains to be comforted, and days ahead with half-stitched wounds'. Several distinctions are found due to cultural differences from Korean parents. First, whereas the Western parents see the cause of their child's suicide as his/her independent issue, the Korean parents blame themselves entirely. This may have stemmed from the overly inter-dependency between the parents and the child. Second, whereas the Western perspective views the suicide as a type of illness from the individual's depression. The Korean perspective views the suicide as a shame that disgraces the parents or the family. This negative social perspective intensifies the self-blame and social isolation. Third, the Westerners recognize the prevention and responsibility of suicide resting with the society and government, but the Korean society recognize suicide as personal or family matter. Based on the finding above, I proposed a number of practical measures to aid the surviving parents who belong to a group with extremely high suicidal rates.

The purpose of this study was to review the agreement and disagreement logics on privatization of health care to bring quality enhancement of medical service and alienated area without medical services at the same time, to identify the core keywords through language network analysis a kind of contents analysis on the editorials dealing with privatization of health care and hospitals for profit published on the major daily newspapers for the recent three years, and to find out what is the core of the controversy through the connection centrality analysis of core keywords. Conclusively, it was found from the centrality analysis that "medical service," "hospital," "privatization," "privatization of health care," "hospital for profit" and "Government" were situated in the center of the controversy. It is natural that keywords such as "medical service," "hospital," "privatization," "privatization of health care"and "hospital for profit" were located in the center because this study reviewed the editorials published on major newspapers for the recent three years regarding the privatization of health care or hospital for profit. Next important keywords (words) were "people," "health"and "health insurance." It shows that privatization of health care was not simply seen as the opening of medical service market but as an important issue related to health of people and health Insurance. Next words with high centrality were "objection" and "allowance." Through the contents analysis of editorials for the last three years, it was found that the opinions for and against the privatization were equally matched according to the centrality analysis result. On the other hand, there is one noticeable result in centrality analysis, which is the keywords such as "US," "Korea US" and "FTA" showed centrality to some extent. It shows privatization is handled relating US and Korea US FTA by editorials.

Often a network becomes complex, and multiple entities would get in charge of managing part of the whole network. An example is a utility grid. While the entire grid would go under a single utility company's responsibility, the network is often split into multiple subsections. Subsequently, each subsection would be given as the responsibility area to the corresponding sub-organization in the utility company. The issue of how to make subsystems of adequate size and minimum number of interconnections between subsystems becomes more critical, especially in real-time simulations. Because the computation capability limit of a single computation unit, regardless of whether it is a high-speed conventional CPU core or an FPGA computational engine, it comes with a maximum limit that can be completed within a given amount of execution time. The issue becomes worsened in real time simulation, in which the computation needs to be in precise synchronization with the real-world clock. When the subject of the computation allows for a longer execution time, i.e., a larger time step size, a larger portion of the network can be put on a computation unit. This translates into a larger margin of the difference between the worst and the best. In other words, even though the worst (or the largest) computational burden is orders of magnitude larger than the best (or the smallest) computational burden, all the necessary computation can still be completed within the given amount of time. However, the requirement of real-time makes the margin much smaller. In other words, the difference between the worst and the best should be as small as possible in order to ensure the even distribution of the computational load. Besides, data exchange/communication is essential in parallel computation, affecting the overall performance. However, the exchange of data takes time. Therefore, the corresponding consideration needs to be with the computational load distribution among multiple calculation units. If it turns out in a satisfactory way, such distribution will raise the possibility of completing the necessary computation in a given amount of time, which might come down in the level of microsecond order. This paper presents an effective way to split a given electrical network, according to multiple criteria, for the purpose of distributing the entire computational load into a set of even (or close to even) sized computational loads. Based on the proposed system splitting method, heavy computation burdens of large-scale electrical networks can be distributed to multiple calculation units, such as an RTDS real time simulator, achieving either more efficient usage of the calculation units, a reduction of the necessary size of the simulation time step, or both.

UNIDROIT Principles of International Commercial Contracts(PICC) was published in 1994. PICC has been functioned as a guideline of international commercial contracts, an applicable law to govern a contract by the agreement of the parties to a contract, general principles of law and lex mercatoria. In addition, PICC has a role of interpreting or supplementing international uniform law instruments as well as domestic laws, and also has served as a model for national and international legislations. PICC has been accepted as a authoritative source of knowledge of international trade usages of international commercial contracts to the arbitral tribunal rather than domestic court because it excluded the characteristics of hard law at the drafting stage. This article dealt with the rule on gross disparity of validity which fall outside the scope of UN Convention on Contract for the International Sale of Goods(CISG), which has obtained a leading legal position of uniform law in international sales of good. In other words, PICC suggests a series of meaningful solutions to the issue of gross disparity of contract which is the most complicated among legal disputes occurring during the process of conclusion of contact and also extremely different and diverse between legal systems. This article covered the issue of gross disparity of contract at the conclusion of contact and suggested the legal basis of several rules related to the gross disparity by analysing gross disparity rule of PICC. Furthermore, this article suggested legal check points or implication as well as interpretation and evaluation on doctrine of laesio enormis and undue influence or unconscionability. This article also dealt with a comparative analysis with Principles of European Contract Law(PECL) and Common European Sales Law(CESL) which have important legal positions in the area of international commercial contract as well as in terms of close relationship to PICC by linking with recent court or arbitral tribunal rulings.

In this study, we analyze and forecast quantum computer technology trends. Previous research has been mainly focused on application fields centered on technology for quantum computer technology trends analysis. Therefore, this paper analyzes important quantum computer technologies and performs future signal detection and prediction, for a more market driven technical analysis and prediction. As analyzing words used in news articles to identify rapidly changing market changes and public interest. This paper extends conference presentation of Cha & Chang (2022). The research is conducted by collecting domestic news articles from 2019 to 2021. First, we organize the main keywords through text mining. Next, we explore future quantum computer technologies through analysis of Term Frequency - Inverse Document Frequency(TF-IDF), Key Issue Map(KIM), and Key Emergence Map (KEM). Finally, the relationship between future technologies and supply and demand is identified through random forests, decision trees, and correlation analysis. As results of the study, the interest in artificial intelligence was the highest in frequency analysis, keyword diffusion and visibility analysis. In terms of cyber-security, the rate of mention in news articles is getting overwhelmingly higher than that of other technologies. Quantum communication, resistant cryptography, and augmented reality also showed a high rate of increase in interest. These results show that the expectation is high for applying trend technology in the market. The results of this study can be applied to identifying areas of interest in the quantum computer market and establishing a response system related to technology investment.

This study is regarding what motion modality has influences on aspects of genre and media. Nowadays, motion modality becomes an element which is actively manipulated in live actions as well as animations. And, it has been generally accepted that a strategy on manipulation of motion depends on matters of genre or medium. As respected, can we say the premise is correct? if it is, can we refine the premise more theoretically, without using the words, 'genre' or 'media' which have not been are not been defined on an academic aspect. I intend to discuss on this issue. I will speculate the issue of manipulation of motion modality on theoretical bases. According to McLuhan's hot/cool media theory and Bolter's oscillation theory, the effect of it turns out to be same as manipulation of sentience ratio of media readers, and the ideal result will be examined by an example analysis. In the analysis, I will explore what effects manipulation of motion has on several examples. Then, by examining what kind of correlation these effects has with media/genre positioning, I ultimately will evaluate the genre/medium-based determinism of motion modality, which is represented by a typical premise like "Animation is most realistic when it has the most animation-like movement." Conclusively I suggest a refined premise like the following. Modality of motion is a strategy depending on issues of genre, with no regard to issues of medium, and the issue of genre is a category which is positioned considering mixture ratio of sentience. With this reason, A strategy of modality of motion depends to sentience a certain sequence needs. So, motion modality becomes a strategy which has to be approached in functionality of genre rather than economic values which spring from technical devices like a motion capture.
