  • Purpose - This study examines the changes in the mobile MMORPG market in recent years and the factors affecting the performance of mobile games through flow experience according to the characteristics of game content. Research design, data, and methodology - This study focuses on the fact that the cause of game use behavior changes is the flow experience which influences the duration of mobile game continuation. The flow experience and the influencing factors are divided into the relationship between first, second-leading factors, and lagged factors. Results - The user's sense of challenge, skillfulness, concentration, and reality influenced the flow experience as a leading factor influencing the performance of MMORPG games. On the other hand, fun and preference were found to be the outcomes of the flow experience. This is because the game content is experienced not through passive enjoyment but by intentionally enjoying the game content. The flow experience has a positive effect on the intention of continuous use as in the previous study. Conclusions - This study found that the flow experience of game users is necessary for continuous use by organizing relationships of flow experience in mobile MMORPG users' gaming behavior.

  • 본 논문은 퍼지와 의미특징을 이용한 새로운 스니핏 추출의 성능향상 방법을 제안한다. 제안방법은 문장집합의 의미특징을 이용하여 대표문장을 생성하고, 대표문장과 문장집합의 퍼지관계를 이용함으로써 질의를 잘 나타내는 스니핏을 추출한다. 또한 의사연관 피드백을 이용하여 질의를 확장함으로써 사용자의 의도가 의미적으로 더 잘 포함되는 스니핏을 추출할 수 있다. 실험결과 제안방법이 다른 방법에 비해서 스니핏 추출에 더 좋은 성능을 보인다.

  • XML은 데이터와 문서를 표현하기 위한 표준화된 메타언어고서 점차 많은 분야에서 사용되고 있지만, 각 분야에서 XML 문서론 올바르게 처리하기 위해서는 XML 컴파일러를 작성해야 한다. XML 컴파일러를 작성하는 많은 시간과 노력을 필요로 하기 때문에 XML 컴파일러를 자동적으로 생성할 수 있는 방법이 필요해진다. 논문에서는 XML 문서를 의미에 맞게 처리할 수 있는 XML 컴파일러를 자동으로 생성할 수 있는 XCC라는 XML 컴파일러 생성기를 소개한다. XCC는 XML문서의 DTD를 입력으로 받고, XML 원소(element)들 간의 관계를 이용해서 상속과 컴포지션 관계를 갖는 자바 클래스들을 생성한다. XCC는 또한 의미 규칙을 입력으로 받아서 XML 문서를 의미에 맞게 처리하기 위한 XML 컴파일러를 생성한다. XCC는 XML, 컴파일러를 자동적으로 생성함으로써 XML문서 처리를 위한 소프트웨어 개발에서 비용을 절감시킬 수 있다

  • 유비쿼터스 컴퓨팅 기술을 기반으로 주변 상황을 인식하고 그에 따른 상황인지 서비스를 실현하기 위한 많은 연구가 진행되고 있다. u-City에서는 도시의 곳곳의 센서 등을 통해 상황 정보가 수집되고, 개인들은 자신의 모바일기기와 도시의 정보 통신 인프라를 통하여 상황인지 서비스를 제공 받게 된다. 본 논문에서는 u-City의 네트워크에 연결된 센서나 디바이스에서의 정보를 구조화하는데 유용하고 상호 관계성 및 부분적인 상황의 정보를 표현할 수 있는 OWL(Web Ontology Language)을 사용한 온톨로지를 설계하고, 수집된 상황정보와 사용자의 의도를 기반으로 서비스를 추론하는 맞춤형 u-City 서비스 제공을 위한 상황인지 추론 시스템을 제안한다.

  • Objective: The aim of this study is to suggest three-dimensional(3D) hand gesture taxonomy to organize the user's intention of his/her decisions on deriving a certain gesture systematically. Background: With advanced technologies of gesture recognition, various researchers have studied to focus on deriving intuitive gestures for commands from users. In most of the previous studies, the users' reasons for deriving a certain gesture for a command were only used as a reference to group various gestures. Method: A total of eleven studies which categorized gestures accompanied by speech were investigated. Also a case study with thirty participants was conducted to understand gesture-features which derived from the users specifically. Results: Through the literature review, a total of nine gesture-features were extracted. After conducting the case study, the nine gesture-features were narrowed down a total of seven gesture-features. Conclusion: Three-dimensional hand gesture taxonomy including a total of seven gesture-features was developed. Application: Three-dimensional hand gesture taxonomy might be used as a check list to understand the users' reasons.

  • The purpose of this study is to understand how the factors related to quality in child care services effect decision making of parents to use such services again, using the parameter of parental satisfaction as a measure. In order to support the researcher's hypothesis, data was gathered from 566 households who send their children to one of the child care facilities in Goyang-Shi, Gyeonggi-Do. The collected data was then analyzed by means of structural equation modeling. The results of the analysis showed that the higher the level of assurance, service tangibility and empathy were, the more the parents were satisfied with the service. The more they were satisfied, the possibility of using the service again increased relatively. In conclusion, various political and practical implications were also addressed and discussed on the basis of these results, with the aim to improve the factors of quality in child care services and parental satisfaction.

  • Technological developments facilitate payment transactions. In 2020, Bank Indonesia issued a regulation that supports QR payments using the Indonesian Standard Quick Response Code (QRIS). PT ABC is one of the banks that launched a QR payment feature on mobile banking with QRIS standards to make it easier for customers to make payment transactions at various merchants. In its implementation, the interest of QR payment users still tends to be small, so an analysis of the interests of QR payment users is carried out. The purpose of this study is to analyze the factors that influence user interest by using a modified UTAUT model. The UTAUT model was modified by adding variables to perceived trust, perceived risk, perceived regulatory support, and promotional benefits. The population taken is the company's customers in the DKI Jakarta area and it takes 403 samples for this case study. The results of empirical analysis show that 8 out of 12 hypotheses are considered proven where business expectations, social influence, perceived trust, perceived risk, perceptions of regulatory support, promotion benefits, age-moderated performance expectations, and age-moderate effort expectations have a significant effect on behavioral intentions, while performance expectations, facilitation conditions, business expectations are moderated by experience and social influence.

  • Pilot operated control valve for $CO_2$ refrigerant is a valve that can perform various functions according to the user's intention by replacing pilot units, widely used for flow rate, pressure, and temperature control of refrigeration and air conditioning systems. In addition, $CO_2$ refrigerant, that requires high pressure and low critical temperature, can be installed and used in all positions of the refrigeration system, regardless of high or low pressure. In this paper, response characteristics are modeled and analyzed based on behavior of the main piston of the pilot-operated control valve. Although various factors influence operation of the main piston, this paper analyzes the effect of equilibrium pressure depending on valve installation position and application, and inlet and outlet orifice size of the load pressure feedback chamber to determine feedback characteristics of the main piston. As a result, it was possible to quantitatively analyze the effect of change in equilibrium and load pressure feedback chamber flow path size on the change in main piston dynamic and static characteristics.

  • Improving work efficiency and satisfying customers through personalized services is becoming more important in an increasingly competitive hair industry. Wearables may help to improve hair designers' work efficiency and customer satisfaction by analyzing customer and hair designers' conditions and provide hair stylingrelated data. However, there is limited research on developing wearables for hair designers (WHDs), and many existing wearables were developed without understanding user needs and perceptions. This research investigated preferences, perceptions, and intentions on WHDs based on hair designers in the U.S., which is the largest hair market. Specific design options that hair designers preferred and possible options to meet requirements that hair designers expect for wearables were identified and suggested in WHD design guidelines. Second, most people preferred a WHD design of a black-colored bracelet/watch that can be a necklace designed with preferred functions; in addition, 3D virtual images and 3D printed models were prototyped. Third, developed designs were evaluated. More than 70% of users were satisfied and considered it as useful and easy to use, with an intention to purchase. The results are expected to provide insights to designers when developing WHDs.
