Purpose: The peer review process is essential for maintaining the quality of scientific publications. However, identifying reviewers who possess the necessary expertise can be challenging. In Open Journal Systems (OJS), which is commonly utilized by journals, the most effective method of inviting reviewers is when they are already registered in the system. This study seeks to improve the efficiency and accuracy of the reviewer selection process to ensure high-quality peer reviews. Methods: We introduced a process innovation to analyze users within OJS and obtain recommendations for potential reviewers possessing the relevant expertise for the manuscript under review. This study collected user data from OJS as potential reviewers and utilized information from the Scopus search application programming interface (API). We extracted authors’ data from the Scopus API to obtain their Scopus IDs, which were then used to scrape publication data of potential reviewers. The system matched the previous works of reviewers with the title and abstract of the manuscript using term frequency-inverse document frequency and cosine similarity algorithms. Results: The system was evaluated by comparing its recommendations with the assessments made by the editorial team. This evaluation yielded precision, mean average precision, and mean reciprocal rank values of 0.47, 0.77, and 0.87, respectively. Conclusion: The results clearly demonstrate the system’s ability to provide relevant reviewer recommendations. This system offers significant benefits by assisting editors in identifying suitable reviewer candidates from the existing user database in OJS, particularly for the evaluation of manuscripts.

손끝은 최고의 촉각 센서이자 최고의 운동 기관이다. 많은 기술자들은 손끝의 감각에 의존하여 그들의 정 확하고 숙련된 솜씨로 결과물을 만들곤 한다. 컴퓨터 게임 역시 섬세한 조작을 요구하는 분야임에도 불구하 고 제작과 구현의 어려움 때문에 대부분의 게임 인터페이스들은 촉각이나 손이 나타내는 복잡한 표현들은 고려하지 않는다. 또한 VR이 빠르게 발전하고 있고 여러 종류의 가상 환경 몰입형 입력 장치들이 나타나고 있지만, 그들의 기술 수준은 게임 패드에 각종 센서가 추가된 정도에 머무르고 있다. 본 논문에서는 손가락 의 위치를 통한 3D 인터페이스를 설계하는 방법론을 소개한다. 전통적으로 손을 인식하는 입력 방식에서는 주로 몇몇 제스쳐와 간단한 표현들을 인식하는데 그쳤으며, 상대적으로 미소한 손가락 관절의 움직임이나 손 과 손 사이의 상호작용 등의 복잡한 제스쳐에 대해서는 전혀 고려하지 못하고 있다. 본 방법론은 이러한 표 현들을 어떻게 구현할 것인지 제시하며, 손가락의 위치나 각도 등 복합적인 데이터를 계산하여 의미 있는 정 보들을 도출해낼 수 있게 한다. 또한 실험을 위해 구현된 간단한 프로그램에서는 구체적으로 어떻게 작동하 는지와 무엇을 표현할 수 있는지 보여준다. 이를 통해 3D와 몰입형 가상 환경에서 손이 나타내는 복잡한 표 현들을 구현하는데 적용될 수 있을 것으로 예상된다.

Fingertip is both the best touch sensor and the finest actuator. Many technicians depend on their touch of fingertips to regenerate accurate and well-experienced actions. Although computer game is also the area that delicate control is needed, most of game interfaces have no such considerations because they can’t represent tactile impression. Furthermore, as VRs are rapidly evolving, various input interfaces for immersive 3D environments are emerging but their technical level remains on the same stage of gamepad with some sensors. This paper proposes a methodology to design 3D interface that uses positions of fingers. In traditional methods hand-tracking devices usually recognize some gestures and simple expressions. However, this kind of methods don’t consider about some complicated gestures which include comparatively minute finger joints movement and interactions between hands. Proposed methodology presents how to apply these expressions to 3D applications. To derive meaningful outputs from these small expressive controls, it contains many computations among finger position vectors, angles, etc. Following simple application using the method shows how it works and what can it express with hands. Although the quality of results and visual output is not so adorable because of some technical obstacles and artless processes, in conclusion it is expected that this method can be applied to implement complicated hands expressions in 3D and also immersive environment.

Tour application have a lot of information to offer. Because smart phones’ screen is small, it is necessary to efficiently organize user interface(UI). To have a quantity analysis on human's' attention affected by layout position in tour application UI design, an experiment was proposed and then the data analysis was done. Thirty subjects took part in our experiment and 20 tour application layout images divided into four area of interest (AOI) were taken as the stimulus randomly. Data was recorded by the Tobi Pro X2-30 eye tracker system. The heat maps and gaze plot results were analyzed. And then One-way ANOVA (analysis of variance) statistical method was applied to finding out the significant difference in factor levels. Results show that the active area and eye movements tracking roads within statistic meaning. Moreover, ANOVA (F = 24.28, p = 2.21267e􎂡15 < 0.01) shows that the different positions have significance difference effect on subjects' attention and mean of AOI (4) is a significant difference from other three area. And then the influence degree of AOI (4) (F = 13.90, p = 0.098 > 0.05) is weaker than other regions through the simple test. In conclusion, the tour applications should be considered the layout position effects on improving the attraction for corresponding users.

본 연구에서는 해안침투대의 지질 층서 및 염/담수 영역의 영상화를 위하여 전남 영광군 백수읍 일대 해수침투 지역에서 전기비저항 수직탐사, 2차원 전기비저항탐사, 탄성파굴절법 탐사를 적용하였다. 전기비저항 수직탐사와 2차원 전기비저항탐사는 기존의 광역 등가 NaCl 염분도 분포도의 분해능을 보완하여 보다 고분해능의 염/담수 경계 영상화를 목적으로 적용하였으며 탄성파 굴절법 탐사의 경우 연안 대수층의 암상 경계에 대한 분해능 제고를 위해 적용하였다. 또한 지료 물리탐사 자료의 해석 결과를 토대로 선정된 3개 지점에서 확인 시추와 물리검층을 수행함으로써 해석 결과를 검증하였다. 전기비저항 수직탐사 및 2차원 전기비저항탐사 결과 기존의 염/담수 경계가 연구지역의 북동쪽으로, 기존 광역 탐사결과에 비해 내륙 쪽으로 상향 조정될 수 있음을 확인하였으며, 대수층 하부 기반암부에서 저비저항 이상으로부터 기반암 내부 균열을 따른 고염분 지하수의 유입 가능성을 확인하였다. 또한 탄성파 굴절법 탐사를 복합 적용함으로써 해수침투 환경, 특히 천부에 매우 낮은 저비저항 이상대가 존재하고, 동일 측선 내 동일 암상에서도 지하수의 염분도에 따라 체적 전기비저항의 변화가 존재하는 경우 발생하는 전기탐사에 의한 층서 분해능의 저하를 효과적으로 보완할 수 있었다.

We applied geophysical methods such as vertical electrical sounding, DC resistivity, and seismic refraction method for the delineation of lithology and the saline/fresh water interface in the saltwater region of Baksu-eup, Yeonggwang-gun, Korea. Vertical electrical sounding and DC resistivity were applied to enhance the resolution of existing regional salinity map. Refraction survey was applied to improve the resolution of lithologic identification. We also conducted confirmation drilling and geophysical well logging at three locations selected based on geophysical interpretation, and verified our interpretation. According to our interpretation for electrical data we identified that the saltwater-freshwater interfaces may move toward north-east off-shore direction than regional interpretation. We also identified that the electrical methods provides some ambiguity in delineating lithologic boundary in saltwater-intruded condition, especially, when the electrical resistivity changes within the same lithofacies even in the same survey line, and that adopting integrated approach using other method such as seismic refraction method like in this study may reduce the ambiguity.

의학 지식이 빠르게 변화하는 시대에 전통적인 의학교육 방식은 다양한 도전에 직면하고 있다. 이러한 배경에서 IVR(Immersive Virtual Reality) 기술은 높은 몰입감과 상호작용성을 바탕으로 의학교육의 새로운 대안으로 주목받고 있다. 본 연구는 IVR 기술을 기반으로 한 초음파 의료 교육의 가상 장면 인터페이스 설계 요소를 분석하고, 초음파 의료 사례를 중심으로 이를 심층적으로 탐구하여 의학교육의 질과 효과를 향상시킬 수 있는 핵심 설계 요소를 도출하고 평가하는 것을 목적 으로 한다. 이를 위해 전자 데이터베이스를 통해 선별된 관련 문헌을 분석하고, 몰입감, 상호작용, 현실감, 피드백, 용이성 등 5가지 핵심 설계 요소를 추출하였다. 또한 3개 의료 교육 기업의 IVR 플랫폼을 대상으로 사례 분석을 수행하였으며, 분석은 4단계로 구분하였다. 연구 결과, IVR 기술은 학습자의 학습 경험과 교육 효과를 유의미하게 향상시킬 수 있으며, 특히 이론 지식과 실습 능력 강화에 효과적인 것으로 나타났다. 그러나 현재의 IVR 기술은 현실 환경을 완벽하게 재현하기에는 한계가 있으며, 향후 연구에서는 상호작용, 피드백, 용이성 측면에서의 개선이 필요하다.

In an era of rapidly evolving medical knowledge, traditional methods of medical education are facing numerous challenges. Against this backdrop, Immersive Virtual Reality (IVR) technology has emerged as a promising alternative in medical education, offering high levels of immersion and interactivity. This study aims to analyze the interface design elements of virtual scenarios in ultrasound medical education based on IVR technology and to explore them in depth using ultrasound as a case study. The goal is to identify and evaluate key design factors that can enhance the quality and effectiveness of medical education. To this end, relevant literature was selected and analyzed through electronic databases, from which five core design elements— Immersion, Interaction, Realism, Feedback, and Usability. Additionally, case analyses were conducted on the IVR platforms of three medical education companies, structured into four distinct stages. The findings indicate that IVR technology can significantly enhance learners' educational experiences and outcomes, particularly in strengthening both theoretical knowledge and practical skills. However, current IVR technology still faces limitations in fully replicating real-world environments. Future research should focus on improving interactivity, feedback mechanisms, and usability to better meet the diverse needs of learners across different regions.

In Today’s World, the usage of Web is increased in a very fast manner. The User who is surfing the Web always wants to extract the meaningful information from the resources. As the number of user increased, the Web is diffusing day-by- day. Due to this diffusion, there is enormous lacking in retrieving the relevant information. To overcome this, Semantic Web Technologies such as Resource Description Framework along with Document Object Model are used to bring the clear answers to user queries by taking advantage of the availability of precise semantics of information in the context of the search engines. The Resource Description Framework (RDF) is defined by the World Wide Web Consortium (W3C) which is one of the enrich entity which is mainly used to encode the meaning of the data.

Object oriented (OO) is the most accepted object modeling languages nowadays. Although OO languages are successful in modeling real world entities, nevertheless, there is little to no support for modeling state of object precisely in code. To overcome this problem, a new general purpose programming language is proposed that is built on two paradigms which are typestate-oriented and permission-based. One of the most vital factor for every language to be accepted and effective for users is having an enhanced standard library and clearly one of the most important parts is Input and Output (I/O) Application Programming Interface (API). One of a new programming language is Plaid language. Since the Plaid is at its early stage of development, I/O features provided by the Plaid standard library are very basic and limited. This paper presents I/O API that we have developed for the Plaid based on the features provided by Java I/O API. For the evaluation we used two metrics which are the number of features provided by I/O API, and the number of exceptions eliminated by using Plaid and typestate-oriented programming language.

An Application programming interface or API is a set of routines, protocols, and tools for building software applications. A good API makes it easier to develop a program by providing all the building blocks. A programmer then puts the blocks together. Many companies provide free API services which can be utilized in Control Systems. SCADA is an example of a control system and it is a system that collects data from various sensors at a factory, plant or in other remote locations and then sends this data to a central computer which then manages and controls the data. In this paper, we designed a scheme for Weather Condition in Internet SCADA Environment utilizing data from an external Application Program Interface. The scheme was designed to double check the weather information in SCADA.

Securities and investment services had the most data per company on the average, and used the most data. Investors are increasingly demanding to invest through their own analysis methods. Therefore, securities and investment companies provide stock data to investors through open API. The data received using the open API is in text format. Python is effective and convenient for requesting and receiving text data. We investigate there are 22 major securities and investment companies in Korea and only 6 companies. Only Daishin Securities Co. supports Python officially. We compare how to receive stock data through open API using Python, and Python programming features. The open APIs for the study are Daishin Securities Co. and eBest Investment & Securities Co. Comparing the two APIs for receiving the current stock data, we find the main two differences are the login method and the method of sending and receiving data. As for the login method, CYBOS plus has login information, but xingAPI does not have. As for the method of sending and receiving data, Cybos Plus sends and receives data by calling the request method, and the reply method. xingAPI sends and receives data in the form of an event. Therefore, the number of xingAPI codes is more than that of CYBOS plus. And we find that CYBOS plus executes a loop statement by lists and tuple, dictionary, and CYBOS plus supports the basic commands provided by Python.

In the past year, the northbound interface application has become a hot topic in the Software-Defined Network technology. It offers an opening method and makes people able to develop own business application upper the SDN. In this paper, we propose and evaluate a visual plane based on android phone application to present an explicit watch of the state and working performance of the Openflow-based underlying network topology in Software-Defined Network. The impacts of the designing architecture are evaluated in the form of software simulation and actual operating effects of the android application that we have designed.

So this paper wants to achieve the unified dispatching by elaborated methods and transplants the idea to the android application. By the way of the software programming, we could make the android phone to probe the southbound network resources through the northbound interface whose connotation we will expand. Between the northbound interface and the android application, we introduce a data center and select the mysql database to implement its function. Through the technology framework we built, we are able to use an android phone to access the status of the underlying devices and monitor the software defined network better aiming at providing better service. And we judge its function from the perspective of overall feasibility and stability not only through the system performance but also sound experiment effects. Finally, we can use any android phone to view about the topology of the network effectively and simply.

The single most important concept to master when designing mobile device interfaces is "context". The context in which an application is used and the context of how information is input are both key issues; each must be understood before a well-crafted design may be implemented. When these two notions of context are explored, it becomes clear that designing for a mobile device can lead to a solution that is worlds different than its desktop equivalent. In this paper, we developed a graphical user interface of mobile application to control a digital audio system remotely. Most significantly, this remote control mobile application for the control of digital audio must be able to control many channels simultaneously. The number of input channels is 4 and the number of output is 8. Also, it has a lot of graphical components and has many kinds of components that are controlled by the mobile application. It creates an experience especially for many users of digital audio, allowing the user to interact with the software for digital audio operation in a natural and intuitive way. As a result, we implemented the mobile application interface of digital audio to provide a user-friendly experience. An efficient memory management is also necessary in order to execute the operation for the remote control and hard cording is needed on the mobile application. To solve that problem, a GridLayout was used. As a result, the screen size is not problem in operating the mobile application on android.

인간은 사회적 동물로서 타인과의 접촉빈도나 관계의 질이 행복에 큰 영향을 미치므로 인간의 행복지수를 높 이기 위해서는 공동체 활성화가 필요하다. 공동체 활성화를 위해 해외에서는 이웃들끼리 자연스럽게 만나 사 회적 네트워크를 형성하고, 공동체의 결합과 화합을 증대시킬 수 있는 커뮤니티 가든(community garden)을 주 목해 오고 있으며 우리나라에서도 이와 유사한 형태의 도시농업을 추진하고 있다. 그러나 국내의 도시농업은 아직 대부분이 개인적인 범위에서 이루어지고 있어 본격적인 공동체로 발전하지는 못하고 있는 상황이다. 따 라서 본 연구에서는 도시농업을 활용하여 산업화와 도시화로 인해 잃어버린 도시민들의 공동체 의식을 되살리 기 위하여 소셜 네트워크 서비스 기반 도시농부 커뮤니티 어플리케이션을 디자인하였다. 본 연구는 문헌연구를 통해 공동체와 도시농업에 대해 살펴보고, 선행연구에서 제시하는 공동체 활성화 요인 을 도출하여 미국의 커뮤니티 가든 사례에서 공동체 활성화 요인과 관련된 활동을 정리하였다. 이렇게 정리된 활동들을 중심으로 기능을 도출하였고, 전문가 인터뷰를 통해 주요 기능을 국내실정에 맞게 보완하였으며, 타 겟 유저와의 인터뷰를 통해 공동체를 활성화시킬 수 있는 추가적인 니즈를 발굴하여 최종 기능으로 도출하였 다. 이를 바탕으로 각각의 공동체 활성화 요인별로 1개의 기능을 선정하여 인터페이스 프로토타입을 디자인하 였다.

Vitalizing a community is an important factor to increase the human being’s happiness degree because the relationship quality with others affect to the degree. For such a reason, the community garden was considered as a good way to vitalize a community in other countries and the urban farmers’ community garden has been promoted in Korea. However, the urban farmers’ community gardens have not vitalized the community so far whereas the community gardens in other countries have done. Therefore the authors of this paper designed an SNS-based application to support the vitalizing of the urban farmers' community. First, the authors reviewed literature to understand what the community and the urban farmers’ community garden. Second, the authors collected the factors for vitalizing a community from the previous research and analyzed the cases of community gardens in other countries based on the collected factors. Third, the authors developed functions that might vitalize the urban farmers’ community and enhanced them by the expert interview and target user interview. Finally, the authors designed five user interface prototypes for five functions selected from five factors.

HTML 기반 웹 어플리케이션의 여러 단점을 보완하기 위한 대안으로 RIA 기반의 웹 어플리케이션이 주목받고 있다. 그러나 RIA 기반의 웹 어플리케이션이 제공하는 인터페이스가 실제로 사용자들의 사용성을 향상시키는지에 대한 연구는 미비한 상태이다. 따라서 본 연구에서는 RIA 기반 웹 인터페이스와 HTML 기반 웹 인터페이스에 대한 사용자들의 테스크 수행 속도와 에러 횟수 등을 측정하여 효율성을 평가하고, 사용자들의 감성적 만족도를 측정함으로서 기존 HTML 기반 인터페이스와 비교 하여 RIA 기반 웹 인터페이스의 효율성이 증가하였는지 또한, HTML 기반 인터페이스와 RIA 기반 인터페이스에 대한 사용자들의 감성적인 만족도는 어떠하며 효율성과 감성적 만족도와는 어떤 상관관계가 있는지에 대하여 알아보았다. 이를 통하여 RIA 기반 인터페이스의 가치와 한계를 확인함으로써 향후 구체적인 연구의 방향을 제시 할 수 있었다.

모바일 디바이스의 대중화로 스마트폰과 같은 모바일 디바이스들은 이제 우리 생활에 없어서는 안 될 중요한 디바이스로 자리 잡았다. 이와 동시에 어플리케이션의 개발 열풍으로 다양한 기능들의 어플리케이션들이 쏟아져 나오고 있는 실정이다. 이는 위치기반서비스 어플리케이션인 내비게이션에서도 마찬가지이다. 모바일 디바이스에서 지도 어플리케이션을 비롯해 내비게이션 어플리케이션은 이미 보편화 되는 추세이다. 몇 년 전만해도 자동차 내비게이션 시장에서는 이런 현상을 예상하지 못한 채 이제는 모바일 디바이스에 거의 종속된 상태이다. 이에 따라 기존 자동차 내비게이션에 최적화된 사용자 인터페이스와 사용자 경험은 다시 모바일 디바이스에 최적화되는 문제를 되풀이 하게 되었다. 스마트폰은 특성상 휴대가 용이해야 함으로 스크린의 크기에 제약을 받기 때문에 사용자 인터페이스 디자인과 사용자 경험 디자인은 기존의 차량용 내비게이션과는 다를 수밖에 없다. 특히 내비게이션 어플리케이션에서 색채는 사용자에게 시각적으로 매우 중요한 요소로 작용하고 있다. 이러한 관점에서 본 연구는 스마트폰에서 내비게이션 어플리케이션을 위한 색채 디자인 분석과 사용성 평가를 실시하여 색채 적용성에 관한 연구를 실시하였다.

Mobile devices like a smart phone or smart pad become a very indispensible thing in our common life by becoming popular it. At the same time, a number of applications with various functions for mobile devices are pouring by developing application fever. it is also a same situation in a location based application. This trend is becoming common already not only map application but also GPS navigation for car. Even as recently as several years ago, Nobody could expect this situation and the navigation system was subordinate to mobile devices. For this reason, the user interface design and user experience design that have been optimized in the car navigation have to be optimized to mobile devices again. The smart phone has to be easy to carry, therefore it has a restriction of size. Especially, the color in the navigation application is very important element visually. Thus, we conducted an applicability comparison of the color system in navigation application for the smart phone through the analysis of the color design of the application and user test.
