In this paper, the difficulties involved in analyzing and designing a management system for product development are discussed with reference to reducing the impact of products on the environment. We propose some models and methods to analyze information behavior in the process of product development based on a fusion model which integrates the assessments of users’ needs, the environment, and available technology. These models and methods are subsequently applied to the development of a new packaging material. The results of this case study allow us to identify effective information for the design of a management system for product development to reduce the impact of products on the environment.

직업재활은 장애인이 직업을 통하여 비장애인과 동일한 삶을 영위하게 돕는 과정으로 정확한 직업평가를 통해 수행된다. 이러한 직업평가의 전통적인 방법은 평가도구를 사용하거나 상담 등을 이용한다. 하지만 전통적인 방법에서 사용되는 평가도구들은 일반 사용자들이 사용하기에는 고가이며, 이러한 평가도구를 사용하기 위해서는 보유하고 있는 장애인시설로 이동해야하는 불편함이 있다. 따라서 최근 꾸준히 보급되어 2011년 이용자수가 1천만명을 돌파할 것으로 예상되는 스마트폰을 사용하여 장애인이 직접 직업평가를 수행하는 경우에 시 공간에 제약을 받지 않아 매우 효율적이다. 본 논문에서는 스마트폰용 운영체제의 일종인 안드로이드환경에서 장애인들을 대상으로 직업평가를 수행할 수 있는 모바일 적성검사 시스템을 설계하고 구현한다. 직업평가 도구로서는 전 세계적으로 진로지도와 상담에서 가장 많이 사용되고 있는 홀랜드 검사를 바탕으로 구현한다.

Assessment of information credibility is a ubiquitous human activity given that people constantly make decisions and selections based on the value of information in a variety of information seeking and use contexts. Today, people are increasingly engaging in diverse online activities beyond searching for and reading information, including activities such as creating, tagging and rating content, shopping, and listening to and watching multimedia content. The Web 2.0 environment presents new challenges for people because the burden of information evaluation is shifted from professional gatekeepers to individual information consumers. At the same time, however, it also provides unprecedented opportunities for people to use tools and features that help them to make informed credibility judgments by relying on other people's ratings and recommendations. This paper introduces fundamental notions and dimensions of credibility, and contends that credibility assessment can be best understood with respect to human information behavior because it encompasses both the level of effort people exert as well as the heuristics they employ to evaluate information. The paper reports on a survey study investigating people's credibility judgments with respect to online information, focusing on the constructs, heuristics, and interactions involved in people's credibility assessment processes within the context of their everyday life information activities. Using an online activity diary method, empirical data about people's online activities and their associated credibility assessments were collected at multiple points throughout the day for three days. The results indicate that distinct credibility assessment heuristics are emerging as people engage in diverse online activities involving more user-generated and multimedia content. A heuristic approach suggests that people apply mental shortcuts or rules of thumb in order to minimize the amount of cognitive effort and time required to make credibility judgments. The paper discusses why a heuristic approach is key to reaching a more comprehensive understanding of people's credibility assessments within the information-abundant online environment.

무기체계는 과학기술의 발전에 따라 S/W 중심으로 변화되고 있으며 다양화 복잡화되고 있다. 무기체계 S/W 사용자의 상황인식 수준은 신속 정확한 판단에 영향을 미치기 때문에 훈련 시 정확한 평가가 필요하다. 그러나 기존 무기체계 S/W 사용자의 상황인식 수준은 단순 상황해결 유무 또는 평가자의 정성적인 판단으로 평가되고 있다. 본 연구는 무기체계 S/W 사용자의 상황 인식 수준을 체계적이고 정량적으로 평가할 수 있는 평가 프로세스를 제안하고자 한다. 본 연구에서는 ACT-R(Adaptive Control of Thought-Rational) 인지아키텍쳐에 인지공학 이론인 SA (Situation Awareness)와 Fitts' Law를 접목하여 사용자의 상황 인식 수준을 정량적으로 나타내는 Cognition Ratio 개념을 제안하였다. Cognition Ratio는 지각(Perception)과 행동(Psychomotor)을 포함한 인지 행동 과정 중 인지(Cognition)의 비율로 구성되었다. 또한, 본 연구는 Cognition Ratio를 활용하여 사용자 상황인식 수준을 정량적으로 평가할 수 있는 평가 프로세스를 개발하였다. 본 연구에서 개발된 평가 프로세스는 다양한 무기체계 S/W 사용자의 상황인식 수준을 효과적으로 평가하는 데 유용하게 활용될 수 있을 것으로 기대된다.

The Rio Grande Compact Commission, in collaboration with local water management entities, water users and universities established a three state Rio Grande The Rio Grande Compact Commission, in collaboration with local water management entities, water users and universities established a three state Rio Grande Salinity Management Program. The objectives of the Rio Grande Project Salinity Management Program are to reduce salinity concentrations, loading, and salinity impacts in the Rio Grande basin for the 270 mile river reach from San Acacia, New Mexico to Fort Quitman, Texasto increase usable water supplies for agricultural, urban, and environmental purposes. The focus of this first phase of the program is the development of baseline salinity and hydrologic information and a preliminary assessment of the economic impacts of salinity. An assessment of the economic impacts of salinity in this region was conducted by scientists at Texas A&M University's AgriLife Research Center at El Paso and New Mexico State University. Economic damages attributable to high salinity of Rio Grandewater were estimated for residential, agricultural, municipal, and industrial uses. The major impact issues addressed were: who is being affected the types of economic impacts the magnitude of economic damages overall and by user category and identification of threshold-effect levels for different types of water use. Salinity concentrations in this 270 mile reach of the river typically range from 480 ppm to 1,200 ppm, but can exceed 3,000 ppm in the lower section of this reach. Economic impacts include reductions in agricultural yields, reduced water appliance life, equipment replacement costs, and increased water supply costs. This preliminary economic assessment indicates annual damages of $10.5 million from increased water salinity. Under current water uses, municipal and industrial uses account for 75% of the total estimated impacts. However, agricultural impacts are based on current crop pattern yield reductions and, salinity leaching requirements and do not account for the impacts of reduced revenue from having to grow salinity tolerant, lower value crops. Actual damages are anticipated to be significantly higher with the inclusion of these additional agricultural impacts plus the future impacts from the growing population in the region. A more comprehensive economic analysis is planned for the second phase of this program. Results of the economic analysis are being used to determine the feasiblity of salinity control alternatives and what salinity reduction control measures will be pursued.

The popularization of smartphones allows people to instantly get the information that they want, through mobile apps, including financial services, movies and public transportation reservations, games and shopping. Furthermore, leisure activities through overseas travel are increasing due to the improvement of the living standards of people. These increases in overseas travel and the use of mobile apps lead to the increased use of mobile travel apps when booking tour packages. Although there are many studies on the usability assessment and user interface improvement for mobile apps, studies on the usability assessment for mobile travel apps are limited. We tested the usability for mobile travel apps to present some suggestions for improvements so that anyone can purchase travel packages easily and simply. We selected the top three mobile travel apps on Rankey.com that have different UIs. The heuristic method was used to evaluate usability. We present a better UI to allow users to use the app functions more easily by analyzing user interaction, ease of learning, readability, efficiency, and satisfaction for the entire use.

Meteorological Joint Frequency Function required indispensably in long-term air quality prediction models were discussed for practical application in Korea. The algorithm, proposed by Turner(l964), is processed with daily solar insolation and cloudiness and height basically using Pasquill's atmospheric stability classification method. In spite of its necessity and applicability, the computer program, called STAR(STability ARray), had some significant difficulties caused from the difference in meteorological data format between that of original U.S. version and Korean's. To cope with the problems, revised STAR program for Korean users were composed of followings; applicability in any site of Korea with regard to local solar angle modification; feasibility with both of data which observed by two classes of weather service centers; and examination on output format associated with prediction models which should be used.

Consumer's switching behavior from incumbent smartphone to new one can be explained by not merely rational assessment but also affective aspects like aesthetic or pleasure and emotional points like attachment. but, in information system field, researches on affective.emotional factors relatively were insufficient and researches which focus on the perspective of the consumer were more scarcity. consumer's attachment to current smartphone brand and perceived aesthetic on new one would influence rational evaluation to switch or not. Therefore, this study investigates relationship between emotional factors on current smartphone and assessment of new one, in turn, we empirically analyzes purchase intention of the consumer. In order to prove the validity of the hypotheses, this study was applied longitudinal study and then conduct a survey of 212 smartphone users. The analysis results by Partial Least Square (PLS) approach showed that all hypotheses in this study were statistically supported.
