User churn in games often arises due to inadequate game difficulty. To address this, non-player characters (NPCs) has been utilized to modulate difficulty according to individual game skill. Nevertheless, the effectiveness of solely NPC-based adjustments is limited since game difficulty is influenced by both NPCs and environmental factors. This paper introduces a novel method for dynamically tailoring game difficulty by adjusting in-game environments based on player behavior patterns in top-down shooter game. Through analysis of diverse user game play data, we find that factors within the game environment, such as the distribution of enemy characters and the arrangement of terrain, have a substantial influence on the level of difficulty. Furthermore, it has been observed that behavioral patterns of players show variations according to changes in the game environment. Using these analytical result, we devise an artificial neural network model that configures an environment that suit player behavior patterns. With the model, we figure out the user player pattern and control the difficulty dynamically by changing the environment factors. Through the experiments, we show that our method provides an appropriate level of difficulty for users to prevent user churn.

산갈치(Regalecus russellii)는 대부분을 심해에서 보내며 가끔 연안에 나타나는데, 그 이유는 명확히 알려져 있지 않다. 우리나라 에서 산갈치는 주로 동해 연안을 따라 출현하는데, 특히 자망 등 어구에 의해 포획되는 경우와 연안에 좌초되어 출몰하는 경우가 높고 그 빈도는 극히 낮다. 또한 발견된다고, 하더라도 산갈치와 형태학적으로 유사한 투라치(Trachipterus ishikawae)로 판별되는 경우가 높다. 산갈 치의 표본을 구하여 분석하는 것은 제한적이기 때문에, 이러한 이유로 우리나라 연안에 출현하는 산갈치의 생태학적 특징에 대해 거의 알려져 있지 않다. 본 연구는 2023년 3월 14일 강원도 앞바다에서 어획된 산갈치의 해부학적 특징을 관찰하였고, 해양 부이 자료를 이용 한 수온 분석을 진행하였다. 분석 결과 산갈치는 수컷이었고, 전장은 320 cm, 전중은 27.52 kg, 체고는 26.62 cm, 생식소 중량은 619.45 g, 간 중량은 218.71 g이었다. 산갈치의 위는 난바다 곤쟁이류로 가득 차 있었고, 산갈치가 어획되기 약 일주일 전부터 15~30 m 수심에서 강한 수온 변동이 있었으며, 저층 수온은 10℃ 미만이었다. 본 기술보고는 우리나라 동해 연안에서 나타날 수 있는 산갈치의 생태학적 특징을 이해하기 위한 기초 자료로 활용될 수 있을 것이다.

Purpose: This study was conducted to understand the ethical climate, nursing practice environment, and ethical sensitivity of hospital nurses, and to investigate the influence of the ethical environment and nursing practice environment on ethical sensitivity. Methods: The subjects of the study were 137 nurses with at least one year of work experience. Date collection was conducted from July to August 2021, using the IBM SPSS Statistics 26.0 for Windows program(IBM Corp. Armont, NY, USA), the frequency and percentage, mean and standard deviation and Independent t-test, one-way ANOVA, Pearson’s correlation, Multiple regression analysis. Results: As a result of the study, the ethical sensitivity of hospital nurses showed statistically significant differences according to age, marital status, position, and ethical educational experience. Ethical sensitivity was found to have a significant positive correlation between all sub-factors of the ethical environment and all sub-factors of the nursing practice environment. Among the sub-factors of the ethical environment, the factor influencing ethical sensitivity in this study is ‘relationship with peers (β=.20, p=.034) ’ and ‘relationship with manager (β=.24, p=.023) and the explanatory power was 42.0%, which was statistically significant (F=8.26, p<.001). Conclusion: This study confirmed that ‘relationship with peers’ and ‘relationship with managers’ influence ethical sensitivity among ethical environments. Therefore, it will be necessary to form a positive relationship between peers and managers to improve the ethical sensitivity of hospital nurses.

One-dimensional MgO nanostructures with various morphologies were synthesized by a thermal evaporation method. The synthesis process was carried out in air at atmospheric pressure, which made the process very simple. A mixed powder of magnesium and active carbon was used as the source powder. The morphologies of the MgO nanostructures were changed by varying the growth temperature. When the growth temperature was 700 °C, untapered nanowires with smooth surfaces were grown. As the temperature increased to 850 °C, 1,000 °C and 1,100 °C, tapered nanobelts, tapered nanowires and then knotted nanowires were sequentially observed. X-ray diffraction analysis revealed that the MgO nanostructures had a cubic crystallographic structure. Energy dispersive X-ray analysis showed that the nanostructures were composed of Mg and O elements, indicating high purity MgO nanostructures. Fourier transform infrared spectra peaks showed the characteristic absorption of MgO. No catalyst particles were observed at the tips of the one-dimensional nanostructures, which suggested that the one-dimensional nanostructures were grown in a vapor-solid growth mechanism.

In the rapidly changing online shopping environment, resulting from the impact of the COVID-19 pandemic, companies are implementing sales promotions, such as offering various discount coupons, to increase consumers' product purchase volume. They are also attracting consumers through low-price appeals, with the expectation of improving sales. However, sales promotions issued by companies have numerous usage conditions, and consumers need to make appropriate efforts to meet the stated conditions. Previous research on promotions and consumer behavior has primarily focused on analyzing monetary promotions (such as full discounts) or non-monetary promotions (such as reward points) individually, with little attention paid to a comparative analysis of the two. Additionally, the type of promoted product can impact consumer behavior.

Today, the ability to engage customers is a key factor of brand competitiveness in global markets. Not surprising, marketers are scrambling to figure how to utilize social media and other digital platforms to motivate customer engagement (CE), defined as brand-focused behavioral manifestations, other than purchases, resulting from individual and group motivational drivers. In this study we adopt consumer investment in trademarks perspective, suggesting that consumers proactively use global brand’s signs to express themselves, affirm values, communicate, and experience pleasure in digital platforms. The brand owners deploy trademarks to protect the symbols, which can distinguish the goods or services of a brand owner from those of other enterprises. We hypothesize that by registering trademarked signs in the host markets, global brands may facilitate CE and achieve superior performance. We empirically test these proposition using data for 125 global brands and trademark finings these brands in the twenty largest economies. The results of model confirm expectations that both trademarking in the host markets and consistency in using protected signs positively affected brand’s market share. The study provides managerial, theoretical, and policy insights in context of global brand protection.

NFTs are touted as revolutionary to market and monetize digital assets. However, critics have questioned NFT value, labeling it as fraudulent. Despite mixed reviews, various firms are leveraging NFTs as a value proposition for customers. In this study, using service-dominant (S-D) logic, we explore how NFTs can help firms in value co-creation and service exchange. We propose and test a conceptual framework using a multi-method approach -1) we investigate NFTs popularity using historical news articles spanning ten years, 2) we use a case study to examine business NFT use in value co-creation and service exchange, subsequently, proposing a conceptual framework illustrating such value exchange, 3) we test our conceptual framework by analyzing data from multiple sources, including surveys, online forums, social media, and transactions. Results from our study, provide business valuable insight into using NFTs as value co-creation and service exchange tool.

As the importance of online virtual spaces increases due to COVID-19, interest in online virtual spaces using 4th industrial technology is increasing. Accordingly, the metaverse that combines virtual and real is becoming an issue. In the fashion industry, marketing using online is gradually increasing, and various attempts are being made by converging with the metaverse to provide new and enjoyable experiences to customers. This study looked at the impact of customer experience of a luxury fashion brand pop-up store on customer satisfaction, affective commitment and brand loyalty in a metaverse environment where utilization is increasing due to COVID-19 and technological development. For the analysis data of this study, a survey was conducted on the users who experienced the metaverse platform Zepeto's ' BVLGARI World'. As a result of examining the effect of the customer experience of a luxury fashion brand pop-up store on customer satisfaction, affective commitment, and brand loyalty in a metaverse environment, some of the customer experiences affect customer satisfaction, and the proposed hypothesis was partially accepted. In addition, it was confirmed that customer satisfaction affects affective commitment and brand loyalty, and affective commitment affects brand loyalty. In this study, we examine the impact of the customer experience of a luxury fashion brand pop-up store on customer satisfaction, affective commitment, and brand loyalty in the metaverse environment, and identify what is needed for more active convergence and activation of the metaverse and fashion brands. Also, we provide practical implications to people who involved in the metaverse and the fashion industry.

Political conflicts and trade tensions affect entrepreneurial activities. This paper qualitatively evaluates the success factors of a B2B company’s marketing management strategies within the context of trade policy changes. Results indicate that a strong brand, personal ties to customers, retailers and competitors, and international manufacturing sites reduce the risk. Companies not only face the challenge of disruptive innovation caused by global digitalization activities. In addition, disruptions in the macro-environment are actually increasing. One example that impedes the growth of industrial activities is the current, still escalating, US-China trade war. Unusual forms of marketing coalitions and networks in trans-organizational systems are considered key constellations to ensure future company success (Achrol, 1991). What are the success factors for a B2B company’s marketing management strategies within the context of disruptive economic market and industry conditions, e.g., international trade policy changes?

The objective of this study is to compare the efficiency of VR and 2D in the tourism industry as marketing tools, using affective forecasting and purchase intention. Accordingly, this study has two primary research aims. The first is to examine if a higher level of mental imagery (resulting from VR) is more effective than a lower level (2D) in a tourism marketing context. To evaluate this, the researchers use experimental method, measuring predicted dominance, predicted pleasure and predicted arousal, as well as purchase intention towards the hotel. Relevant to the tourism industry, tourism products are spatially and temporally distant (vs. near). This study aims to investigate how differently mental imagery, resulting from VR (versus 2D) experience, generates affective forecasting of a tourism product when tourists plan distant (versus near) future trips (temporal distance).

In many situations, consumers have to make a sacrifice (e.g., price premium, loss of personal comfort and efficiency) when choosing a green product over its traditional alternative. Utilizing attribution theory, we offer a set of research propositions as an attempt to explain how consumers may rationalize their perceived sacrifice in making green purchases. First, we posit that consumers’ internal attribution (i.e., individual behaviors cause environmental degradation) enhances their green purchase behavior. Second, internal attribution would generate senses of self-efficacy and guilt, which lead to motivations to accept the perceived sacrifice in purchasing green products. Third, when green purchase indicates a significant sacrifice, consumers tend to develop a coping strategy by switching attribution of responsibility to others, and thus the influence of internal attribution on green purchase will be weakened.
