This paper is an integrated system with Manure Pallet Pool System(MPPS) and Agricultural products Pallet Pool System(APPS). This is an management tool that helps to successfully reduce logistics cost and improve pallet availability. It allows enterprise leaders to create profit through system structure improvement. Already traditional PPS is implemented by pallet rental company, but it is irrationally. In the integrated system proposed MPPS-and-APPS, this describes how to combine and implement and measure rental pallet rate. Using a newly developed management technique for MPPS-and-APPS, i.e., 2-dimensional contract, this system can motivate manager and employee to develop their company Furthermore, this paper is useful of performance measure and application in operational unit.

As a futuristic construction model, building information model (BIM) based project management system (PMIS) and mobile BIM simulator apps have been showing visible sign. However, researches on the BIM based 3D simulator using mobile device are hard to find result from limitation of mobile device (slow speed at huge 3D file, display size, and etc.) and undefined standard of business processes. Therefore, this research aims at studying application of mobile BIM apps based on cloud computing. Total 8 BIM cloud apps were selected and analyzed in the 5 application feasibility characteristics (speed, view, inquiry, markup, and usability). This research would be essential phase to construct BIM based mobile project management system using cloud computing in the future.

Medication adherence is a basic and important element in diabetes management, and it has been known the adherence rate should be keep over 80% to get positive result in diabetes management. In order to increase medication adherence, there have been smart phone apps that record medication, exercise, and diet. However, diabetes patients are generally over 50s, and most of them do not use smart phones. Therefore, in this paper, we propose a medication adherence help system that support both smart phone apps and feature phone SMS. Furthermore, we introduce system architecture for the system. Our work will help ICT-based diabetic management system developers to consider some issues for mobile based diabetic management systems..

Web applications typically interact with databases. Therefore, it is very crucial to understand which web components access which database resources when maintaining web apps. Existing research identifies interactions between Java web components, such as JavaServer Pages and servlets but does not extract dependencies between the web components and database resources, such as tables and attributes. This paper proposes a dynamic analysis of Java web apps, which extracts such dependencies from a Java web app and represents them as a graph. The key responsibility of our analysis method is to identify when web components access database resources. To fulfill this responsibility, our method dynamically observes the database-related objects provided in the Java standard library using the proxy pattern, which can be applied to control access to a desired object. This study also experiments with open source web apps to verify the feasibility of the proposed method.

As malicious apps vary significantly across Android malware, it is challenging to prevent that the end-users download apps from unsecured app markets. In this paper, we propose an approach to classify the malicious methods based on permissions using Long Short Term Memory (LSTM) that is used to embed the semantics among Intent and permissions. Then the malicious method that is an unsecured method will be removed and re-uploaded to official market. This approach may induce that the end-users download apps from official market in order to reduce the risk of attacks.

Cars have become a necessity in modern life. It is widely used to transport people or products to a destination conveniently. However, the addition of a navigation service that provides route information and more makes driving more convenient and safer. Recent developments in the mobile app ecosystem encourages people to adopt not only an installation-type car navigation, but also a mobile app navigation, supporting connected car concepts. It should be noted that mobile apps with mobile Internet can be a significant linkage between information acquired online and offline business. This study demonstrates the impact of the app use experience for a driver in the context of applying artificial intelligence service. As a result, the introduction of artificial intelligence services has a statistically significant moderating effect on the use of mobile navigation apps. This seminal research is valuable as it evaluates the role of artificial intelligence applied to mobile navigation apps.

Recent studies have indicated that mobile markets harbor applications (apps) that are either malicious or vulnerable, compromising millions of devices. Some studies indicate that 96% of companies' employees have used at least one malicious app. Some app stores do not employ security quality attributes regarding authorization, which is the function of specifying access rights to access control resources. However, well-defined access control policies can prevent mobile apps from being malicious. The problem is that those who oversee app market sites lack the mechanisms necessary to assess mobile app security. Because thousands of apps are constantly being added to or updated on mobile app market sites, these security testing mechanisms must be automated. This paper, therefore, introduces a new mechanism for testing mobile app security, using white-box testing in a way that is compatible with Bring Your Own Device (BYOD) working environments. This framework will benefit end-users, organizations that oversee app markets, and employers who implement the BYOD trend.

Purpose The purpose of this study is to examine the variables affecting user satisfaction through previous studies and to examine the differences between apps. Differences are based on factors that determine the quality of real estate service apps and derived by the topic modeling results. Design/methodology/approach This study conducts topic modeling to find factors affecting user satisfaction of real estate service apps using user reviews. Sentiment analysis is additionally conduct on the derived topics to examine the user responses. Findings Users give high sentiment scores for services that can manage factors such as usefulness of information, false sales, and hype. In addition, managing the basic services of app is an important factor influencing user satisfaction.

본 논문에서는 최근 주요시설의 경계에 주로 사용되기 시작한 라이다 센서를 여러대 사용할때 보다 효율적으로 사용하기 위해서 통합된 3차원 좌표계에서 시각화하는 방법에 대해 설명한다. 주로 카메라 기반 CCTV의 경우 정확성은 높지만 시야각(Field of View)이 좁기 때문에 레이더(RADAR)센서와 같은 센서와 함께 혼용되는 경우가 많다. 레이더 센서의 데이터는 넓은 범위에 대한 감지를 할 수 있지만 노이즈가 많고 물체의 형상을 정확하게 측정하기 힘들다. 라이다(LiDAR) 센서는 레이져를 이용하여 멀고 넓은 범위를 정교하게 측정할 수 있다. 이러한 라이다 센서는 정교한 만큼 처리해야할 데이터의 양이 많으며, 다수의 센서를 이용하더라도 하나의 화면에서 처리하기 힘들다는 단점이 있다. 제안하는 논문은 여러개의 라이다 센서에서 측정한 데이터를 실시간에 하나의 좌표계로 통일하여 하나의 영상을 보일 수 있도록 통합 뷰잉 환경을 제공한다.
