In the evaluation of Broadband-ISDN, the main issue is to interconnect existing LANs and MANs to B-ISDN based on Asynchrous Transfer Mode. However, LANs provide connectionless services, whereas the ATM network provides connection-oriented services. So some problem arises from accessing ATM switchs to transparently transmit connectionless data via B-ISDN. Two methods then were recommended by ITU-TS to support the connectionaless services. In the paper, we do the numerical analysis, using the stochastic fluid flow method, of dynamic bandwidth allocation sheme with two class traffics in the virtual path established between Interworking Units(JWUS) interconnecting LANs to an ATM network and Connectionless Servers(CLSs). The loss mechanism of each traffic is controlled by the contents of buffer. The vandwidth which the IWU requests the CLS is estimated by the number of On-Off sources in the On state. We use the stochsastic fluide flow method which is to find the steady-state joint probability in each level of the IWU buffer. The length of the IWU buffer as the real random variable is changed by traffics entering the IWU.

In this paper, the investigation about the elevation control and the formation of the free surface of magnetic fluids is carried out theoretically and experimentally on the basis of magnetic fluids is carried out theoretically and experimentally on the basis of Rosensweig' Ferrohydrodynamic Bernoulli Equation. Governing equations of magnetic fields are solved using the concept of vector potential. While applied magnetic fields are induced by 4$\times$4 electromagnet located under the magnetic fluid, the fee surface of the magnetic fluid is formed the balance of surface force, gravity, pressure difference, magnetic normal pressure and magnetic body force. The results of numerical simulation and experiment show the formation of the free surface of the magnetic fluid. Using PID control, an experiment for the elevation control of the free surface of magnetic fluids is performed.

This study on the influence of the brand value and consumption tendency of a catering company on customer satisfaction and behavioral intention. It is demonstrated to contribute to the creation of a competitive corporate brand by using it as an internal marketing data of a catering company following the overflow of many brands. It was analyzed, and through this, we tried to find an efficient way to manage the brand. Through theoretical considerations on the brand value of food service companies, the economic, quality, and social value factors were selected as the independent variables of the pursuit plan, the impulse pursuit, and the pursuit variables. Also, as a dependent variable, satisfaction and behavioral intentions were used in the selection study. Afterwards, a hypothesis and a research model that can confirm the causal relationship between brand values, consumption tendencies, and satisfaction and behavioral intention factors were used for empirical analysis. As a result of verifying all hypotheses, the catering industry is a special sector in which the growth of a company is measured according to brand values. In this aspect, it is time to develop a system that can enhance brand value. Through the results of this study, it was found that the differentiation of the brand value of a catering company would develop each company's brand value well, which would be a great sketch of corporate performance.

Business environment has changed rapidly in the 21st century and the speed is unimaginable. In the quickly altering age, it is the most important for many enterprises to promptly make a decision and immediately deal with changes. These alternations lead to reorganization and new employment environment of enterprises. As a result, people cannot secure lifetime jobs anymore and career cycle shortens as product life cycle does. Based on the above findings, This study on organizational culture in hotel kitchen was conducted on the assumption that a variety of organizational cultures can exist in an organization, and the organizational culture were divided into two categories. Independent variables were dual commitment and career change intention. hotel enterprises can make practical suggestions to effectively use and manage their employees who play a significant role in competitive strategies. Furthermore, this study is meaningful for hotel enterprises finding qualified workers who will be committed to them in the quickly transformed business environment.

This study conducted a statistical analysis on the reliability of self-reported responses regarding decisions on future occupations made by middle school students when participating in a survey related to career choices. The research data comprised 997 responses from a survey conducted among the entire student population of eight middle schools in the Y district of P Metropolitan City in South Korea. The results of implementing multiple logistic regression using career maturity, gender, and grade as independent variables showed that among these factors, only career maturity was significant in predicting the classification of groups. Among the three groups of respondents who answered the survey with decisions made, uncertain, and undecided regarding career choices, 47.3% of the decision-making group, 75.8% of the uncertain group, and only 22.9% of the undecided group matched the predictive classification. Based on the research results, implications for career studies targeting middle school students were drawn, and the limitations of the study as well as directions for future research were suggested.

This study confirmed the necessity and possibility of using Augmented Reality content in real estate services. The characteristics of AR content were categorized according to device and recognition technology, in order to present AR contents that are optimized for the real estate industry. In addition, a survey was conducted to identify the awareness and necessity of real estate AR content among real estate service users. The survey found that overall, there is a high degree of discomfort with the current real estate service. Users reported significant levels of inconvenience, particularly related to scheduling visits with real estate agents and the discomfort they experienced when customizing interiors. Second, the degree of use of immersive media and digital services currently launched by real estate services was investigated. The adoption of web-based and immersive content in real estate, apart from applications, was generally low. Additionally, the usage rate of the recently added 360-degree VR content was also found to be low. Thirdly, real estate AR contents that are likely to be useful in the future were investigated. The results were found to be related to the inconvenience of the current real estate service investigated earlier. Respondents indicated that AR content that enables them to view and interact with real estate information in an actual environment and allows users to customize the space would be highly useful. Lastly, it was shown that expectations for real estate AR content were generally high. Respondents stated that real estate AR content is necessary for the real estate industry, specifically for traders and interior decorators. Respondents expressed a high willingness to use AR content in real estate. Overall, these results suggest that AR content has the potential to overcome the problems associated with the current real estate service. Therefore, it is crucial for real estate services to actively consider developing and utilizing AR content in the future. 본 연구는 다양한 분야로 발전되고 있는 증강 현실 콘텐츠를 부동산 서비스에서 사용해야 할 필요성과 가능성에 대해 확인하였다. AR 콘텐츠를 기기별, 인식 기술별로 특성을 정리하여 부동산에 최적화된 콘텐츠를 제시하였고, 설문 조사를 통해 부동산 AR 콘텐츠에 대한 부동산 서비스 이용자들의 인식과 필요성을 파악하였다. 조사 결과, 먼저 현재의 부동산 서비스에 대한 불편도는 전반적으로 높은 것으로 나타났다. 특히, 이용자들이 중개업자와일정을 맞추어 함께 방문해야 하는 부분에서 그 불편도가 높게 나타났고, 인테리어 커스터마이징 부분에서도 이용자들의 불편함을 알 수 있었다. 두 번째로는 현재 부동산 서비스에서 출시한 실감 미디어 및 디지털 서비스의 이용도를 알아보았다. 애플리케이션을 제외한 웹과 실감 콘텐츠의 이용률은 전반적으로 낮게 나타났으며, 최근 부동산 서비스에 추가된 360도 VR 기술 또한 높은 이용률을 보이지 못했다. 세 번째로는 미래에 유용하게 사용될 부동산 AR 콘텐츠에 대해 조사하였다. 결과는 앞서 조사한 현재 부동산 서비스의 불편함과 연관성 있는 것으로 나타났으며, 중개업자 없이 부동산 내용을 실제 환경에서 볼 수 있는 AR 기능과 공간을 커스터마이징할 수 있는 AR 콘텐츠에 대한 유용성이 높을 것으로 예측했다. 마지막으로는 부동산 AR 콘텐츠의 기대감이 전반적으로 높은 것을 확인하였다. 이용자들은 부동산 AR 콘텐츠가 부동산 산업을 위해 필요하며, 특히 거래자와 인테리어업자를 위한 서비스라고 인식했다. 최종 소비자의 개별 사용 희망률 또한 높은 것으로 나타났다. 위의 결과로 본다면 현재의부동산 서비스의 문제점은 AR 콘텐츠로 극복할 수 있을 것이라는 긍정적인 자료로 해석된다. 따라서 앞으로의 부동산 서비스는 AR 콘텐츠의 개발과 활용을 적극적으로 고민해야 할 것이다.
