Abstract1)Recent scandals of milk additives in several developing countries provoked controversy about quality issue of dairy products, grapping academic attention to the dairy supply chain. In this paper, we first focus on moral hazard problem of self-interested entities about the quality across the dairy supply chain, due to unobservable and unverifiable quality management efforts of all entities – including dairy producers, stations, and a final producer – and high inspection cost for the quality. Based on the identified moral hazard problem, we understand why the adoption of IoT-based tracking systems about quality produced from each entity is a must, different from RFID-based tracking systems.

A robust adaptive control approach is proposed for underactuated surface ship linear path-tracking control system based on the backstepping control method and Lyapunov stability theory. By employing T-S fuzzy system to approximate nonlinear uncertainties of the control system, the proposed scheme is developed by combining “dynamic surface control” (DSC) and “minimal learning parameter” (MLP) techniques. The substantial problems of “explosion of complexity” and “dimension curse” existed in the traditional backstepping technique are circumvented, and it is convenient to implement in applications. In addition, an auxiliary system is developed to deal with the effect of input saturation constraints. The control algorithm avoids the singularity problem of controller and guarantees the stability of the closed-loop system. The tracking error converges to an arbitrarily small neighborhood. Finally, MATLAB simulation results are given from an application case of Dalian Maritime University training ship to demonstrate the effectiveness of the proposed scheme.

HNS사고는 대규모 화재와 폭발을 수반하며, 다수의 인명사고와 주변지역에 극심한 환경오염을 야기함으로 신속한 의사결정을 통하여 광범위한 확산을 막아야 한다. 본 연구는 국내 HNS사고사례를 해상이라는 특수성이 반영된 표준코드를 바탕으로 고품질, 표준화, 디지털화된 HNS사고 데이터베이스를 구축하여 사고발생 시 신속하고 합리적인 의사결정을 지원하고, 체계적인 통합관리 및 공유가 가능한 HNS사고이력관리시스템(HATS)을 설계하고 구현하였다. 또한 개발된 시스템을 활용하여 23년간 수집된 국내 HNS사고데이터 76건에 대해 각 항목별로 통계분석을 수행하여, 국내에서는 매년 평균 3.3건의 사고가 일어나며, 주요 HNS사고요인은 춘계기간 (41%), 계류장 (51 %), 케미컬운반선 (49 %), 승무원에 의한 과실 (45 %), 자일렌류 (12 %)인 것으로 확인되었다.

For several years, keyboard and mouse have been used as the main interacting devices between users and computer games, but they are becoming outdated. Gesture-based human-computer interaction systems are becoming more popular owing to the emergence of virtual reality and augmented reality technologies. Therefore research on these systems has attracted a significant attention. The researches focus on designing the interactive interfaces between users and computers. Human-computer interaction is an important factor in computer games because it affects not only the experience of the users, but also the design of the entire game. In this research, we develop an particle filter-based face tracking method using color distributions as features, for the purpose of applying to gesture-based human-computer interaction systems for computer games. The experimental results proved the efficiency of particle filter and color features in face tracking, showing its potential in designing human-computer interactive games.

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.

Uganda is a country blessed with the biggest number of mountain Gorillas in the whole world. These animals contribute at least 12% in revenue generation to the Tourism sector through tracking by both local and foreign tourists who pay for the tracking permits. However, Gorilla tracking is also a big challenge even in the presence of highly skilled and well-trained game rangers. Development and implementation of a secure Computer and Mobile based Gorilla Tracking (GT) system that uses GIS and GPS technologies would be the most ideal technology to use. Therefore, this study aimed to find out the critical factors that would affect the Behavioral Intention of the would-be users to successfully decide to use such GIS/GPS-GT system. We used the existing UTAUT model to integrate six factors such as Performance Expectancy, Effort Expectancy, Employee Peer Influence, Facilitating Conditions, Behavioral Intention and System Use. However, Infrastructure Availability and Non-Technical Facilitating Conditions were added to reflect Ugandan ICT context. This amended UTAUT model was used to carry out the survey. The questionnaire was emailed to 220 government employees in the fields of ICT, Tour and Travel, Environmental Groups officials and Farmers who garden near the game reserves. A total of 133 were obtained fully completed, whereas 127 were deemed usable thus yielding a response rate of 58%. The analysis results show that except for non-technical facilitating conditions, effort expectancy, peer influence, performance expectancy and infrastructure availability positively affects behavioral Intention to use GIS/GPS-GT. This indicates that people in Uganda don’t bother about regulations and rules in regard to using information system. As long as the system does what they want it to, anything else does not matter. As an employee in an organization is told to use a system by their supervisor, they have no objection to otherwise they risk losing their job. This implies that, supervisors have a great responsibility in the process of developing, implementing and using the system in Uganda.

As well as all other branches of trade, so retail trade itself undergoes various changes and trends with regard to the development of information and communication technologies which affect not only traders themselves but also their customers. It is the retail store environment itself which is one of the decisive aspects of purchase because more than 70% of consumer decisions take place directly at the point of sale. It is the last place which can reverse the purchasing decision. A final customers´ decision is influenced not only by price, quality but also by in-store communication and visual aspects of each store. That is the reason for continuous gathering of feedback on the effectiveness and efficiency of these means of communication in real environment. Besides traditional research techniques there are situations which require the involvement of relatively new research methods. Thanks to the innovative interdisciplinary approach with the use of neuromarketing, it is possible to create effective marketing strategies and thus stimulate the customer attention and emotions. By these emotions, it is possible to achieve better motivation toward purchase and an increase in the number of sales and subsequent raise in income. The paper deals with a complex, interdisciplinary examination of the in-store communication impact on customer visual attention, emotions and related spatial behaviour of customers in grocery stores. Research integrates measurements of mobile eye camera (Eye tracker), mobile electroencephalograph (EEG), face reading technology (FA) and internal position system in real conditions of retail store. The purpose of this research is to recognise the attention, emotional response and spatial customer preferences by means of selected in-store communication tools. At the end of the paper we explain how the neuromarketing methods can be used for better understanding of consumer behaviour at the point of sale.

본 연구는 혁신적 기업에서 감성에 대한 인식 및 활용에 대해 기업의 연차보고서의 내용분석을 통해 밝히고자 하였다. 연차보고서는 현재 기업이 제공하는 상품(제품 및 서비스)에 대한 설명과 기업의 성과 및 방향에 대해 기술하였 기 때문에 기업의 감성에 대한 관심 및 활용을 파악하기 위한 내용분석에 적합한 데이터이다. 감성에 대해서는 그 용어가 국내외에서 혼재되어 사용되고 있어, 연관 단어인 ‘감각’, ‘감성’, ‘정서’와 해당 영단어인 ‘sensibility’와 ‘sense’, ‘emotion’, ‘feeling’, ‘affection’의 사전적 정의를 분석하여 서로의 관계를 분석하였고, 본 용어들을 모두 내용분석에 포함하였다. 혁신적 기업을 선정을 위해 경제 학술지 Fast company에서 발표하는 2009년과 2014년의 ‘The world’s 50 most innovative companies’의 리스트에 포함된 기업으로 추출하였다. 그 기업의 연차보고서를 바탕으로 상호 비교 하여 2009년과 2014년 사이의 감성의 인식 및 활용에 대한 기업의 변화를 추적하였다. 내용분석의 정량적인 결과에서는 혁신성과 감성의 관련성이 강하지 않다고 판단되나, 정성적인 결과에는 5년 사이에 ‘감각(sense)’과 ‘감정(feeling)’에 대한 관심이 증대되고 있음을 확인하였다. 결론적으로, 기업에서 전략적으로 추구하는 혁신성의 방향이 기술 선도 및 차별화에서 사용자 경험 만족으로 옮겨지고 있으며, 사용자의 감각 및 감정을 측정, 평가, 표현하고자 하는 기업의 수가 증대되고 있음을 밝혔다.

해역에서의 체류시간은 제한된 영역을 채우는 수체나 오염물질이 잔류하는 시간을 의미하며, 서로 다른 수체간의 물리적 특성을 비교하는 데 사용되고 있다. 거제만으로 유입되는 육상기원 또는 양식기원 입자물질의 잔류시간을 알아보기 위해 입자추적모델이 포함된 EFDC를 이용하여 입자물질 체류시간을 계산하였다. 계산된 입자물질의 체류시간은 내만에서 약 65일이었는데, 이 결과는 거제만 내측으로 유입되는 입자물질이 외해에 도달하기까지 약 2달 이상의 시간이 소요됨을 의미한다. 이 체류시간은 거제만 전역에 걸쳐 조석의 흐름에 따라 다르게 나타났으며, 해역에 유입된 입자물질의 거동이 해역의 물리적 특성에 의해 결정됨을 의미한다. 입자물질 체류시간의 공간적인 분포특성을 통해 거제 내만의 해수교환이 원활하지 않은 것을 알 수 있으며, 이로 인해 수질오염문제에 취약할 수 있다는 것을 알 수 있다.

최근 국내 의류 시장에서 SPA 브랜드의 급격한 성장을 기반으로 관련 업체들이 기존 의류 이외에 다른 종류의 다양한 제품(SPA 브랜드 확장)을 출시하는 추세이다. 이와 같은 추세 이면의 심리적 기제를 알아보기 위해서 본 연구는 SPA 브랜드 확장에 대한 소비자 정보 처리 과정을 개념적으로 (1) SPA 브랜드 확장과 원 SPA 브랜드 간의 유사성 지각과 (2) 평가(태도와 구입의향)로 구분하였다. 이후 가상의 3종류 SPA 브랜드 확장(저, 중, 고 유사성 조건)에 대한 소비자의 유사성 지각 과정과 평가를 각각 아이트래커와 자기 보고식 설문지를 이용해 측정하였다. 통계 분석 결과, SPA 브랜드 확장의 유사성 지각 과정에서 외적 정보 탐색량과 정보 처리 수준은 ‘중>저>고 유사성 조건’ 순으로 차이를 보였다. 또한 SPA 브랜드 확장에 대한 태도와 구입의향은 ‘고=중>저 유사성 조건’ 순으로 높은 것으로 나타났다. 이와 같은 결과는 SPA 브랜드 확장에 대한 평가가 유사성 지각 정도와 유사성 지각 과정에서 투입된 인지적 노력량에 영향을 받는다는 점을 제안한다.

This study has performed a comparative analysis between groups based on Time To First Fixation, Fixation Duration, Fixation Count and Total Visit Duration, which are eye-tracking analysis indicators on what visual attention is shown compared to the e-magazine produced as regular images related to e-magazines in which experiment subjects have applied cinemagraph images as eye tracking research on the e-magazine produced with cinemagraph images and e-magazines produced with regular images. The experiment sample used e-magazines composed of nine pages while AOI (area of interest) has been set up on each page by classifying image and text regions. A combined 30 people took part in the experiment, which was performed by randomly assigning 15 to the experiment group and 15 to the control group. According to the results of the analysis, the experiment group recorded a shorter time than the control group on the e-magazine produced with cinemagraph images through Time To First Fixation. Though no significant difference was found between the experiment and control groups in Fixation Duration, a substantial difference did appear between Fixation Duration and Total Visit Duration.

태양광 패널로부터 출력을 최대로 얻기 위해서는 신뢰성이 높은 태양광 추적 장치가 설계되어야 한다. 본 논문에서는 LabVIEW 프로그램을 이용하여 퍼지 제어를 기반으로 구현한 2축 태양광 추적 장치 시스템을 제작하여 그 성능에 대해서 알아보았다. 태양광 패널의 움직임을 제어하기 위한 구현된 퍼지 의사결정 시스템의 사용자 인터페이스를 통하여 모든 파라미터를 제어하고 확인할 수 있는 지능제어기와 기계적인 구동부분의 설계가 연구의 중심이 되고 있다. 실제 태양광 추적시스템을 개발하여 환경, 날씨, 계절 및 빛 상태와 같은 영향에 대해서 분석하였다. 태양광 추적장치는 실제 상황에서 시험하였고 시스템 동작과 관련된 모든 변수들은 기록되고 분석되었다. 제안한 태양광 추적시스템을 활용할 경우 고정식 패널에 비해 날씨에 따라 다르지만 최대 약 38% 정도의 더 높은 효율을 얻을 수 있어 자동으로 추적할 때 매우 좋은 결과를 얻을 수 있었다.
