Overleaf is a cloud-based LaTeX editor, allowing users to easily create and collaborate on documents without the need for separate LaTeX installation or configuration. Thanks to this convenience, users from various fields worldwide are writing, editing, and collaborating on academic papers, reports, and more via web browsers. However, the caching that occurs during the process of converting documents written on Overleaf to PDF format poses risks of exposing sensitive information. This could potentially lead to the exposure of users' work to others, necessitating the implementation of security measures and vigilance to caution against such incidents. This paper delves into an in-depth analysis of Overleaf's security vulnerabilities and proposes various measures to enhance the protection of intellectual property.

To understand the synergy of collaboration and to apply this understanding to education, an analysis of how a team solves a problem and the sharing of their mental models is needed. This paper analyzed two things qualitatively to find out the source of synergy in a collaborative problem-solving process. First, the sharing contents in team mental model and second, the process of sharing the team mental model. Ten gifted middle school students collaborated to solve an ill-defined problem called sunshine through foliage problem. The gifted students shared the following results after the collaboration: First, scientific concept prior to common idea or the idea that all group members have before the discussions; second, unique individual ideas of group members; and third, created ideas that were not originally in the personal mental model. With created ideas, the team model becomes more than the sum of individuals. According to the results of process analysis, in the process of sharing mental model, the students proposed and shared the most important variable first. This result implied that the analysis of the order of sharing ideas is important as much as finding shared ideas. Also, the result shows that through their collaboration, the gifted students' shared mental model became more refined and expanded as compared to their individual prior mental models. It is recommended that these results can be used to measure shared mental model and develop collaborative learning models for students.

최근 질병 분석 및 신약을 개발하기 위한 단백질에 대한 연구는 생명 공학의 큰 테마 중 하나이다. 질병 및 단백질 데이터를 분석하기 위한 연구는 대용량의 데이터 처리를 요구하기 때문에 과거 실험을 통해 접근하던 방식에서 벗어나 최근 IT 기술의 결합을 통해 다양한 실험 데이터를 공유하고, 연계함으로써 연구를 가속화하고 있다. 하지만 생명 공학 연구자에게 있어서 IT 지식을 기반을 둔 단백질 분석 도구를 다루는데 많은 어려움이 있다. 이러한 문제를 해결하고자, IT 연구자와 생명 공학 연구자의 협업을 통한 데이터 분석 도구를 개발이 폭넓게 시도되고 있지만, 연구자 간의 협업을 도울 수 있는 통합 인프라는 전무한 실정이다. 본 논문에서는 IT 연구자와 생명 공학 연구자의 협업을 위한 인프라로서 컴포넌트 기반의 질병 및 단백질 데이터 분석 시스템을 설계하고 구현한다.

This study is focused on analyzing the tourism social media channel importance of Trytoursumer. On the basis of previous studies, the factors were divided into tourism communication, tourism cooperation, tourism contents sharing, tourism entertainment. As a result of the empirical analysis using AHP, Analytic Hierarchy Process, tourism communication relatively appeared as the most important factor. And order showed that the high importance of such tourism content sharing, tourism entertainment, tourism cooperation. Also, there was the highest priority of social networking in the area of tourism communication among 14 types of total evaluation factors regarding priority, followed by social news in the area of tourism cooperation, and micro-blog in the area of tourism communication. Analysis result, may contribute to the increase of social media channels effectiveness and strategy of application in social media channel of Trytoursumer.

A design collaboration system for a plant project is a set of complicated multidisciplinary processes in which a large number of various engineering fields are involved. Each subsystem is related to each other as they depend on information that other subsystems create, which leads to inefficient design iterations. This study presents an optimal design collaboration system for a plant project using Design Structure Matrix (DSM). Data regarding design subsystems, parameters, etc. were obtained by expert surveys and workshops. An automatic analysis program for DSM was developed using Visual Basic Application and Matlab to provide a partitioned DSM. A case study was conducted on a furnace project; consequently, the optimal design collaboration system with five crucial iteration groups was derived.

This study proposed a customer preference estimation model for production recommendation and a method to enhance the performance of product recommendation using the estimated customer preference information. That is, we suggested customer preference estimation model to estimate exactly customer's product preference with his behavior. This model shows the relationship of customer's behaviors with his preferences. The proposed estimation model is optimized by learning the relative weights of customer's behavior variables to have an effect on his preference and enables to estimate exactly his preference. To validate our proposed models, we collected virtual book store data and then made a comparative analysis of our proposed models and a benchmark model in terms of performance results of collaborative filtering for product recommendation. The benchmark model means a prior preference weighting model. The results of our empirical analysis showed that our proposed model performed better results than the benchmark model.

This study provides an overview of instruments for mobile contents start-up companies promotion that are currently available in Seoul. It includes a brief description of several different types of start-up companies and development processes for each of those companies so that it can analyze and figure out critical success factors for sustainable growth. In addition, the case studies of five mobile contents related companies are used to obtain more detailed insights into the development processes. The study focuses on mobile contents startups promotion used as a public policy for encouraging more productive and knowledge-intensive ventures, with the aim of upgrading management activities and creating more startups-friendly business environment. Consequently, the key target groups of the measures discussed in the study include mobile contents start-ups and start-ups that exploit new business opportunities in Seoul.

Recently mother company-driven informatization projects have been widely launched for the suppliers. Setting up a proprietary evaluation system for the level of informatization of the suppliers, a mother company provides both financial and consulting supports for the suppliers in order to enhance the utilization level of the ERP(Enterprise Resource Planning) system. With the utilization level enhanced, the whole collaboration network will create a competitive advantage to win over global competition. This paper investigates critical success factors for ERP operational performances through a Samsung Electronics case study. The result of the case study may provide valuable feedback to the strategic decision making and fundamental insights for these collaboration efforts.

Not only Enterprise Application Integration (EAI) within a company but also business-to-business integration (B2Bi) should be achieved for companies to collaborate seamlessly through the Internet. There have been great efforts in this area of EAI and B2Bi, resulting in lots of solutions in the market. However, EAI and B2Bi systems have been designed and operated in independent platforms and environments causing a serious problem of integrating EAI and B2Bi systems. In this paper we have proposed a business integration platform for connecting EAI and B2Bi systems in a uniform architecture and also coping with changes in business environments. In the integration platform proposed in this work, collaboration processes between B2B companies can be performed using Web Services technology widely considered as B2B integration platform. Especially, we have defined basic business execution elements based on a thorough analysis of various business integration standards and developed an efficient and extensible business process engine for B2B collaboration process management. A Web-based order processing system is developed for validation of our integration platform. It is expected that the level of B2B collaboration can be enhanced using the integration platform and furthermore it will contribute to more collaborative B2B commerce.
