최근 국내외로 각광을 많이 받은 마케팅 개념 중 하나가 바로 체험마케팅이다. 특히 업계에서는 체험마케팅에 대한 많은 관심이 있었기에 체험마케팅의 여러 개념과 적용사례가 부각되고 있다. 본 글에서는 체험마케팅에 관련된 주요 오해가 무엇이고 그 실상이 또한 무엇인지 설명하고자 한다. 체험마케팅의 첫째 오해는 체험마케팅이 획기적인 개념이라는 것인데 사실 체험마케팅의 근원이 되는 소비자 반응의 계층, 감성 마케팅, 그리고 통합마케팅 등은 다른 선행 이론에서 잘 정립되었다. 하지만 체험마케팅의 공헌은 이처럼 분할된 여러 개념을 한 틀 속에 응용할 수 있게끔 체계화시켰다는 점이다. 둘째 오해는 체험마케팅의 뜻이 감각마케팅과 통용된다는 것이다. 체험마케팅의 유수 사례 중에는 오감마케팅만을 강조하는 경우가 많은데 성공적인 체험마케팅을 꾀하는 기업은 소비자의 전체적인 체험의 향상을 지향해야 한다. 셋째 오해는 체험마케팅이 감성마케팅만을 강조하고 이성적 마케팅을 간과한다는 생각이다. 체험마케팅은 실제로 소비자의 상황분석에 근거하여 이성과 감성적 마케팅을 둘 다 포괄하는 접근방식이다. 넷째 오해는 체험마케팅의 개념이 너무 추상적이어서 실무에는 큰 도움이 되지 않는다는 주장이다. 하지만 체험마케팅의 실무적인 프로세스를 충실히 따르면 여러 가지의 마케팅 및 조직상의 긍정효과가 나타난다.

In safety-critical systems (SCS), failure may result in accidents with serious damage to human beings and property. As systems become more complex and automated, the goal of acquiring safety has attracted increasing attention lately in the defense industry, as well as the rail, automotive, and aerospace industries, among others. As such, the Department of Defense and international organizations have established appropriate standards and guidelines for systems safety and design. To this end, there has been research on the processes, methods, and associated tools for safety design. However, those results do not seem to sufficiently utilize system architectural information. The purpose of this paper is to provide a more systematic approach to SCS design. To better identify potential hazards, design information at each level of system hierarchy is exploited. Based on the results, an integrated process model was developed by combining the processes of system design and safety analysis. As a case study, the resultant integrated process model was applied to the safety design of an automobile system, which shows useful results for safety evaluation.

본 연구에서는 대한민국 도시 유역에 대하여 딥러닝 네트워크 기반의 분산형 수문 모형을 개발하였다. 개발된 모형은 완전연결계층(Fully Connected Layer)으로 연결된 여러 개의 장단기 메모리(LSTM-Long Short-Term Memory) 은닉 유닛(Hidden Unit)으로 구성되었다. 개발된 모형을 사용하여 연구 지역인 중랑천 유역을 분석하기 위해 1km² 해상도의 239개 모델 격자 셀에서 10분 단위 레이더-지상 합성 강수량과 10분 단위 기온의 시계열을 입력으로 사용하여 10분 단위 하도 유량을 모의하였다. 모형은 보정과(2013~2016년)과 검증 기간(2017~2019년)에 대한 NSE 계수는각각 0.99와 0.67로 높은 정확도를 보였다. 본 연구는 모형을 추가적으로 심층 분석하여 다음과 같은 결론을 도출하였다: (1) 모형을 기반으로 생성된 유출-강수 비율 지도는 토지 피복 데이터에서 얻은 연구 지역의 불투수율 지도와 유사하며, 이는 모형이 수문학에 대한 선험적 정보에 의존하지 않고 입력 및 출력 데이터만으로 강우-유출 분할과정을 성공적으로 학습하였음을 의미한다. (2) 모형은 연속 수문 모형의 필수 전제 조건인 토양 수분 의존 유출 프로세스를 성공적으로 재현하였다; (3) 각 LSTM 은닉 유닛은 강수 자극에 대한 시간적 민감도가 다르며, 응답이 빠른 LSTM 은닉 유닛은 유역 출구 근처에서 더 큰 출력 가중치 계수를 가졌는데, 이는 모형이 강수 입력에 대한 직접 유출과 지하수가 주도하는 기저 흐름과 같이 응답 시간의 차이가 뚜렷한 수문순환의 구성 요소를 별도로 고려하는 메커니즘을 가지고 있음을 의미한다.

In the network economy, the informatization of Small and Medium enterprises(SME) plays an important role in determining productivity while being competitive in the businesses. Informatization of SME has become important along with the recent trend of the fourth industrial revolution. Based on the IT Business Value Model, this study analyzes the key factors of information service of SME with the structure model. In addition, multi-level model was conducted by dividing the layers according to the size of the SME. The analysis confirmed that complementary organizational resources are a key factor in determining the informatization of SME. In addition, the effect of informatization of SME on the scale of SME varies depending on the type of entry into the industrial complex.

Brick toys, once regarded as one of the most basic formative equipments, have succeeded in increasing user base and more experiments have been made to link with a variety of areas in a creative way. However, previous studies on brick were limited to its role as a tool of play and education, which resulted in relatively less number of studies on endless possibility and variability. In this regard, this study examined what made bricks evolve in the unique and advanced form and how it has developed in detail. This study presented information on the basis of theories regarding fundamental features and characteristics of brick and analyzes actual cases in a systematic way. Finally, VR design based on 3D-brick system was implemented.

FEED (Front End Engineering and Design) is the key area that determines the competitiveness of procurement and construction in the EPC contracts especially in terms of the added value. Nevertheless, previous researches in FEED have been limited to the process and deliverable of design work or the particular management business function (e.g. System Engineering, collaboration, information etc.). In this context, the purpose of this study is to propose a comprehensive FEED structure and its functions from the project management perspective throughout the whole project life-cycle for thermal power plants. Proposed FEED business procedures are classified into three levels; First level is the classification of FEED business phases, the second level defines major FEED management functions, and the third level is detailed FEED functions. A survey using proposed FEED functions and assessment variable was conducted in order to analyze the current status and the areas for future improvement. It is expected that the proposed structure, functions, and evaluation methodology for FEED management will contribute to effective practice of FEED as well as to improvement of competitive capability for engineering, procurement, and construction (EPC) companies.

In this paper, performance of IEEE 802.11 carrier-sense multiple access with collision-avoidance (CSMA/CA) protocols in saturated traffic conditions is presented taking into account the impact of imperfect channel sensing. The imperfect channel sensing includes both missed-detection and false alarm and their impact on the performance of IEEE 802.11 is analyzed and expressed as a closed form. To include the imperfect channel sensing at the physical layer, we modified the state transition probabilities of well-known two state Markov process model. Simulation results closely match the theoretical expressions confirming the effectiveness of the proposed model. Based on both theoretical and simulated results, the probability of detection is concluded as a dominant factor for the performance of IEEE 802.11.

Prior art search is a core process of technology management performed by inventors and applicants, patent examiners, and employees in the patent industry. As a result of insufficient academic research on a systematic prior art search methodology, the process has been often carried out depending on the subjective judgment of researchers. Previous studies on exploring prior arts based on semantics have also have the risk of underestimating the similarity of major prior arts due to the nature of patent documents where the same technical ideas are expressed in various terms. In this study, we propose an effective prior art search methodology based on hierarchical citation analysis, which provides a clear criterion for selecting core prior arts by calculating weights according to the relative importance of the collected patents. In order to verify the feasibility of the proposed methodology, a case study was conducted to explore the core prior art of one patent in the display field. As a result, 10 core prior art candidates were selected out of the 206 precedent patents.

There are currently several workflow software products on the market, and they vary in their capabilities and features. Since there is no single workflow product that dominates others in all aspects, it is difficult to evaluate their superiority. Few methods are available about their selection. This paper suggests a decision support method for selecting the most appropriate workflow software products using the Analytic Hierarchy Process method. We prioritize the importance of four classes of workflow applications as well as 13 commercial products.

무선 센서 네트워크 환경에서는 수많은 노드들이 광범위한 영역에 걸쳐 이벤트 정보를 전송한다. 센서들이 이벤트 정보를 정확하고 빠르게 전송하기 위하여 가능한 경로를 탐색하는 라우팅 프로토콜이 반드시 필요하다. 온도와 같은 주변 환경의 급격한 변화를 잘 탐지하도록 설계된 클러스터 기반 계층적 라우팅 프로토콜인 TEEN(Threshold sensitive Energy Efficient sensor Network protocol)을 채택하여 분석하고 단점을 개선하고자 하였다. 따라서 새로운 개념인 SRS(Self Rescue Signal)를 TEEN 프로세스에 적용하여 이벤트 발생 정보를 알 수 없다는 점을 개선하기 위한 방법을 연구하였다.
