The Internet has made a huge impact on the way we, as humans, communicate. During the last decade a series of new communication mediums have emerged and communication protocols have come and gone. This puts new requirements on the development process and architecture of the communication platforms, operated by communities, in order to proactively ensure support for future communication protocols. Even further, additional requirements are added when the software itself will be maintained by a community. In this paper we explore the world of Open Source Software. We present our suggestions of usable design-principles and our process in developing a sustainable information system.

With the development of the Internet of Things, the use of flexible displays has become widespread. In particular, the use of curved, bendable, and rollable displays is increasing. Flexible display production processes include various important components such as lamination material, flexible substrates, and adhesives. Among them, improvement of the lamination process comprises a large proportion of efforts for further development. In this paper, we attempt to improve the transmittance of the display substrate by performing a bubble removal process after adhesion. The transmittance of the glass substrate with the bubble removal process was 5~12% higher than that of the substrate without the bubble removal process. The fill-strength after the bubble removal process was improved by 21.4%, and the shear-strength was improved by 43.9%.

Adversarial attack is a technique that causes a malfunction of classification models by adding noise that cannot be distinguished by humans, which poses a threat to a deep learning model. In this paper, we propose an efficient method to detect adversarial images using Gaussian process regression. Existing deep learning-based adversarial detection methods require numerous adversarial images for their training. The proposed method overcomes this problem by performing classification based on the statistical features of adversarial images and clean images that are extracted by Gaussian process regression with a small number of images. This technique can determine whether the input image is an adversarial image by applying Gaussian process regression based on the intermediate output value of the classification model. Experimental results show that the proposed method achieves higher detection performance than the other deep learning-based adversarial detection methods for powerful attacks. In particular, the Gaussian process regression-based detector shows better detection performance than the baseline models for most attacks in the case with fewer adversarial examples.

입법안은 법률조문 자체로 이해하기 보다는 입법 주체간의 정치사회적 관계 속에서 파악할 필요가 있다. 입법안은 국회의원이나 공무원의 고유권한이라기 보다는 정당, 시민단체, 이익집단, 미디어 등 다양한 입법 주체간의 참여와 역동적 커뮤니케이션을 통해 달성된다. 이 연구는 입법과정에서의 커뮤니케이션 특징과 기능을 살펴보기 위해 국내 입법 현장 전문가들을 대상으로 포커스그룹 인터뷰와 개별 심층 인터뷰를 실시했다. 연구결과는 다음과 같다. 첫째, 국내 입법형성 과정은 입법주체 간의 역동적 상호소통 관계 축에서 이루어졌다. 그러나 그 과정에 커뮤니케이션의 난맥으로 효율적이고 생산적인 입법의제를 산출하고 있다고 보기는 어려웠다. 둘째, 국내 입법형성 과정이 제한적이긴 하지만 과거에 비해 행정부라는 폐쇄적인 공간에서 국회라는 정치적 공론장으로 점차 옮겨가고 있음을 발견했다. 셋째, 입법과정에 전문가 집단의 영향력 확대와 시민단체들의 세력화가 두드러지게 강화되는 특징을 보였다. 국회 입법 보좌관을 비롯해 국회 입법조사관, 국회 전문위원, 국회입법 심의관 등 입법 실무자들이 법안 형성과정에 보이지 않게 영향을 미치는 '인사이더(insider)' 역할을 했으며, 동시에 과거 입법형성 과정에 소외됐던 NGO 등 시민단체들의 부상은 주목할 만한 변화였다. 넷째, 의제형성 과정에서 미디어는 국회에 대해서는 공적이슈 개발의 주체이자 입법의제의 전달자로 그 영향력이 컸지만, 정부에 대해서는 입법의제 형성에 미치는 기능이 매우 제한적이었다. 이 논문은 국내 입법안 과정에 커뮤니케이션이 왜 중요하며, 그 과정에 촉진요인과 장애요인이 무엇인지에 대한 함의를 중심으로 논의했다.

The aim of this paper is to discuss how designers lead and direct 'technology-driven society' using their creative communication skill. To this end, it is required for communication designers to take conscious steps to recognize the future direction of their profession. Despite the advancement in technology, there is a human being at the center of all design activities. From a certain point of view, contemporary communication design takes an open-ended exploration of the subject matter, rather than a finished output. The notion of creative leadership may potentially expand more in terms of improving the methodology of today's visual culture. The paper will examine creative leadership that could be proposed by the challenge of discourse upon the upcoming industrial revolution. Today, communication designers are confronted by new leadership opportunities and challenges. Some leading designers seem to focus on brand new media technologies to prepare the 4th industrial revolutions. However, communication design cannot be discussed in the medium but can be understood as a process. Top-down and bottom-up process is always a concerned about the relationship since the focus of leadership has changed. In the top-down process, the leadership has existed between 'designer and client' because designers have played their role as a problem solver. On the other hand, there is a different model of leadership between 'design and technology' based on bottom-up process, which stem from the design authorship. In this regard, the new definition of creative leadership in the $4^{th}$ industrial revolution proposes a designer as a problem-finder based on the relationship between the 'designer and the public'.

Although precise temperature control in the heat treatment process is a key factor in process reliability, there are many cases where there is no separate heat source control optimization system in the field. To solve this problem, the program monitors the temperature data according to the heat source change through sensor communication in a recursive method based on multiple variables that affect the process, and the target heat source value and the actual heat treatment heat source to match the internal air temperature and material temperature. A control optimization system was constructed. Through this study, the error rate between the target temperature and the atmosphere (material surface) temperature of around 10.7% with the existing heat source control method was improved to an improved result of around 0.1% using a process optimization algorithm and system.

While previous studies argue that BIM-based assembling collaboration promotes the communication and process management among participants in architectural design projects, it is still unknown which communication and socio-psychological factors are more and less activated in use of BIM-based collaboration. To investigate this research aim, in authentic BIM-used architectural retrofitting projects, the participants (N=36) collaborated and assessed the communication factors on (1) perceiving design results, (2)understanding partners'design intention, (3) proposing and converging opinions, the interpersonal design process management factors on (1) managing design process, (2) managing collaboration schedule, and the complementedness factors on (1) understanding partners' expertise, and comradeship. Statistical analyses reveal that the factor relevant to perceiving design results is better activated than the other factors (p<0.05), but all other factors are not much activated compared to perceiving design results. Deduced from the previous BIM studies and interviews, a reason roots in the shared forms and semantics of BIM. The shared semantics represent collaborators' information and allow the participants to perceive design changes explicitly. Meanwhile, BIM-based assembling collaboration is limited to represent observable, experience-able processes of design, and thus, several key socio-psychological factors, such as proposing and converging opinions and managing design process, are less activated.

In this paper, big free standing metal structures for electrostatic MEMS switches are easily fabricated using photoresist sacrificial layer. The entire process sequence, through the removal of the sacrificial layer, is kept below 150 $^{\circ}C$ to avoid curing problem of photoresist sacrificial layer. Metal structure is fabricated by thermal evaporator and a self test electrode is fabricated underlying metal suspended structure for testing by electrostatic force. The new wet release process is considered using methanol rinse, general wet release process cause stiction problem by capillary force during drying, and the yield is dramatically improved than previous wet release process using DI water rinse. The fabrication becomes much simpler and cheaper with use of a photoresist sacrificial layer.

This study examines group process patterns when Instant Messaging is used for decision-making, and examines how these patterns are associated with creative solutions to problems. Our research suggests that certain communication behavior of a group, when appropriately organized, can enhance creative production of outcomes. A qualitative analysis is conducted on communication patterns based on text-based conversation protocols. Specifically, this research tries to extend existing studies on group-work by focusing on the interactive communication process among participants. Study results include that the production of creative outcome depends on the temporal sequence of discussion pattern among group members. (1) Appropriate control of the discussion process is essential to obtain a high level of performance. (2) It is also important to set up discussion rules and rules for the use of communication medium in the early stages of the discussion . (3) Active participants use various protocol types while less-active members rely mainly on 'cognitive' protocols.
