교통망에서 경로의 총 통행비용은 통행비용과 인지비용으로 구분된다. 출발지와 도착지간에 상이하게 인지되는 비용을 고려하여 경로를 탐색하는 것은 전체경로를 열거해야 하는 문제 때문에 현실 적용에 한계가 있다. 따라서 현재 활용되고 있는 첨단교통정보체계(ATIS)에서 경로정보를 제공할 때 통행비용 만을 고려하여 경로를 탐색하는 기법을 적용하는 것이 일반적이다. 본 연구는 경로열거문제 없이 상이한 링크인지비용을 반영하는 최적 및 K 경로탐색기법을 제안한다. 이를 위해 링크를 경로의 최소단위로 정의하고, 따라서 두 링크의 비교가 경로의 비교로 확대되는 링크표지기반경로탐색기법을 활용하며, 도착지를 기반으로 후방향 최적링크인지경로트리를 구축한 후 출발지기반으로 전방향 최적의 링크총비용 경로트리를 구축하는 수식과 알고리즘을 제안한다.

In this study, we analyzed the old`s characteristics for depth perception in comparison with the young`s as a basic study for universal design in field of products or facilities. Twenty three of the old and twenty two of the young had participated and the depth perception apparatus was used in this experiment. Gender, viewing distance, and age were considered as factors and the differences of depth perception were analyzed for each experimental condition. In the result, a significant difference was not detected on gender, but significant differences were detected on age and viewing distance. That is, we can see that the old is remarkably worse than the young on depth perception task. Therefore, it means that these characteristics have to be absolutely considered in user interface design to improve the old`s accessibility for products or facilities.

The purpose of this study was to investigate the effects of youth voluntary on sense of citizenship, positive self-perception, and peer relations, which procedures was conducted by being comparison between middle school students and high school ones. This study also use the data given by 2st of the Seoul Education Longitudinal Study(SELS), which subjects were 7,593 youths(3,566 in middles school students and 4,027 in high school ones). The most significant variable for youth's peer relations was sense of citizenship both middle school and high school student, which indicates not only that it is encouraged by sense of citizenship but also that developing and leading the sense of citizenship for youth should be given by the school welfare policy. Positive self-perception in middle school youth influenced the second effect on their peer relations, but high school student's peer relation was impacted by the voluntary service into a secondary effect.

This study investigates which sound quality indices except SPL raise annoyance response. For investigation, auditory perception experiments for road traffic noise with identical linear SPL were performed by Paired Comparison Method. The numerical results of a Paired Comparison experiment express relative preference about annoyance. So that these relative preference scores are to be correlated to sound quality indices, which are absolute, a transformation is required to go from the relative domain to an absolute and linear scale of preference. The results of the transformation will be the 'merit values,' which quantifies the annoyance(in this case) of the road traffic noise on a linear scale. Using multiple regression, a formula is established that can calculate predicted merit values. Furthermore, This investigation offers a method selecting sound samples that represent various sound quality indices values to use experiment.

Purpose: To develop Pregnancy Risk symptom Perception Scale (PRPS) and evaluate its validity and reliability. Methods: A preliminary 30-item version of PRPS was developed through literature review, in-depth interview, and Content Validity. Each item was scored on a four-point Likert scale. The preliminary scale was developed based on 301 pregnant women who visited a hospital. Date were analyzed using item analysis, factor analysis, confirmatory factor analysis, Pearson's correlation coefficients, and Cronbach's ${\alpha}$ (0.90 for total item, 0.80 to 0.88 for factors). Results: The PRPS consisted of 27 items. Three factors (physical, environmental, and emotional factors) explained 55% of the total variance. Cronbach's Criterion validity was supported by comparison with the Perception of Pregnancy Risk Questionnaire (r=0.34). In reliability test, the reliability coefficient of pregnancy risk symptom perception was high at 0.90. Conclusion: These results suggest that the pregnancy risk symptom perception scale developed in this study comprises items that can assess the level of pregnant women's pregnancy risk symptom perception in Korea. Its validity and reliability were proven. PRPS can be utilized to measure pregnant women's risk symptom perception during pregnancy. PRPS will contribute to the development of systematic prenatal care and effective risk management.

This study is aimed to retain objectivity and generality against consumer perception about seafood of Hebei Spirit oil spill incident area, and analyze gap of consumer perception in according to confidence level of seafood using ordinal logit model. As results, This article have three implications. First, Consumer don't have high confidence level in comparison with previous research. Second, It is important to retain confidence of quality for purchasing seafood of oil spill incident area. Third, Consumer perception is improved positively against seafood of oil spill area. But This study has limits that don't take regional opinion and situation into account.

The purpose of the study is to examine culinary students' perception of the quality of an OJT(on the job training) program and to investigate their satisfaction levels clustered by the differences in it. Through the survey, the data were obtained from 348 culinary students who had experiences of an OJT program. They were analyzed by SPSS 13.0 and divided into four groups based on the differences of perception. As a result, this study showed that the more the students had a positive perception of OJT program, the more they were satisfied with the program. Therefore, this study will be of great use to seek for alternatives for the promotion of OJT program in the future.

This study is to evaluate the risk perception of noise of the ground-crews in the Korean airbases who exposed to noise of jet plane. 1148 ground-crews and 231 pilots of 2 airbases participated in this study. The questionnaires of risk perception with visual analogue scale were completed by the participants. For comparison, the perception of other risks such as beef contaminated with dioxin, AIDS, lung cancer, otitis media, shigellosis, driving, drinking, and smoking were also included in the questionnaire of risk perception. The results of this study suggested the necessity of risk communication about noise and activation of effective hearing conservation program in the Korean air-force.

본 연구는 자아 관여도가 높은 자동차라는 단일 품목의 광고에 대한 한국과 중국 소비자 인식의 유형을 바탕으로 주관성 구조가 어떠한 차이가 있는지를 비교 분석한 것이다. 한 중 소비자 비교 연구를 진행한 이유는 무엇보다 글로벌 시장에서 거대한 잠재력과 빠른 성장력을 가진 중국 소비자의 특성을 구체화시키고자 했기 때문이다. 또한 체제와 사회경제적 특성의 차이에 따라 변화된 한 중 소비자의 특성을 비교함으로써 양국 모두에 유용한 광고전략 아이디어를 제시하고자 했다. 더욱이 세계가 글로벌이라는 단일 시장에서 경쟁해야 하는 현실을 고려할 때, 한국과 중국 소비자의 광고 인식에 대한 주관성 구조를 이해하는 것은 이러한 경쟁에서 우위를 점하기 위한 전략을 세우는 데 유용할 것이다. 연구 결과, 동일한 아시아 문화권인 한국과 중국의 소비자들이 가지고 있는 광고 인식에 관한 주관성 구조는 상이한 결과로 나왔지만, 유사성도 발견되었다. 이러한 결과는 향후 양적 접근을 통해 보다 일반화, 객관화시켜야 한다는 후속 연구의 과제를 안고 있다.

Conspicuous consumption is often investigated in Korea and consumers purchase a product to publicly display economic power or social status. The existing studies argue that brand loyalty and luxury brand preferences escalate conspicuous consumption, and it is important to identify different visual perception to understand irrational consumers' behavior. Car emblem as brands' visual identity represents the brand's image, mission and message. Irrational consumers thus are expected have different visual perception to the emblem or logo. To understand the impact of irrational consumer behavior on visual perception, this study explored how brand loyalty and luxury brand preferences impact on the visual perception of car emblems between Korean domestic brand and imported brand. This study used eye tracking technology to measure the respondents' attention on an emblem of the cars. Eye tracking tools analyze fixations and measure the attention on a specific area of interests (AOI). This study explored the maintaining time and frequency on AOI, as well as explored the size of pupil to identify the respondents' attention on the AOI. In this experiment, the logos of domestic cars (i.e., Hyundai and Kia) and foreign cars (i.e., Mercedes-Benz and BMW) were swapped to see how irrational consumer behavior impact on visual perception of car emblem.
