  • 본 연구는 딜레마구간 제거를 위한 기초연구로서, 황색신호 등화시 신호교차로에 접근하는 차량들의 운전자 행태를 분석하는데 그 목적이 있다. 이를 위해 도시부 2개 지점(송탄, 수원 영통)과 지방부 1개 지점(용인)의 신호교차로를 대상으로 차량들의 정지 감속률과 운전자 인지반응시간, 그리고 딜레마 구간과 정지율과의 관계를 고찰하고 이를 바탕으로 신호교차로의 정지율과 이에 따른 딜레마구간의 범위를 도출하였다. 본 연구를 통해 우리나라 운전자들의 정지감속율과 운전자인지반응시간(PRT)은 각각 1.61m/sec$^2$과 1.27초를 보였다. 이러한 값들은 그동안 우리나라에서 사용되어왔던 ITE 기준보다 큰 값들로서 향후 신호교차로에서의 안전을 고려한 설계시 매우 중요하게 다루어야 할 것으로 보여진다. 또한 본 연구는 향후 조사 대상 범위를 더욱 확대하여 다양한 운전자 행태에 대한 자료를 수집하여 향후 신호교차로 안전시스템 개발시 적극 활용될 수 있으리라 판단된다.

  • 본 연구는 대중교통을 이용하는 여성통행자가 차내에서 발생하는 성범죄로부터 안전하게 이동할 수 있도록 성범죄피해 현황을 파악하고 개선방안을 제시하기 위하여 수행되었다. 대중교통내에서 발생하는 성범죄 피해현황을 파악하였으며, 이러한 경험이 성범죄를 예방하기 위한 정책을 도출하는데 어떠한 영향을 미치는지 분석하였다. 분석방법은 경기도 직장여성들을 대상으로 심층면접조사를 수행하여 성범죄 피해실태를 파악하고 적절한 대응방안을 모색하기 위하여 구조방정식 모형으로 인과관계를 분석하였다. 그 결과, 여성들은 CCTV와 경고음 설치, 경찰인력의 추가 배치는 성범죄예방에 효과적으로 판단하고 있으나, 여성전용칸 설치는 실효성이 낮은 것으로 평가하였다. 이러한 결과에는 각 개인의 주관적 규범과 지각된 행동통제가 중요하게 영향을 미치는 것으로 나타났다. 이러한 분석결과에 근거하여 대중교통 성범죄 예방을 위한 정책적 대안을 제시하였다.

  • 에이전트가 지각이나 행위의 표상을 이해할 수 없는 이유는 의미론적 자질을 문자열로 변환하는 구문론적 표상방식에 의해서 일어난다. 자율적으로 학습하는 인지 에이전트를 구현하기위해 코헨은 에이전트가 sensor와 effector를 사용하여 주위환경과 물리적으로 직접적인 상호작용을 통하여 물리적 스키마의 의미 표상을 학습하는 의미론적 방법을 제안하였다. 본 논문에서는 부정(negation)은 그러한 물리적 스키마를 인식하게 하는 메타 스키마임을 제안한다. 최근에 Graphplan은 계획 시스템의 성능을 향상하기 위하여 inconsistency를 이용하는 제어규칙을 사용하지만, 구문론적으로 접근하여서 부정의 의미 개념을 이해하지 못하고 중복표현의 문제를 야기한다. IPP는 부정 함수인 not을 도입하여 중복문제를 해결하지만 여전히 구문론적으로 접근하며 또한 시간과 공간에서 비효율적이다. 본 논문에서는 의미론적인 접근법을 도입하여 부정을 위해서 반대 개념이라는 긍정 아톰(atom)을 사용하는 것이 지능 에이전트를 구현의 효율적 기법이라고 제안하고, 이 가설을 지지하는 실험적 결과를 제시한다.

  • This research investigated the consumption of various rice-based processed foods of 279 housewives in Daegu. 70% of the housewives that responded to the question graduated from a high school or college, was 30∼40 years old and full-time housewives. The main places for purchasing the rice-based processed foods were large size discount store and supermarkets, as other industrial products and the family′s preference was the most critical factors in choosing the products. The fact that the main reason of purchasing the rice breads and cookies, instead of wheat, was "They may be good for health” indicated many housewives have a positive perception of rice-based foods. Among the rice-based processed foods, the using frequency of rice cake (dduk) was the highest, with rice cookies and rice drinks being the next most frequent. However, the frequencies of cooked rice (bob) and rice flour were very low. An analysis of the correlation for the using frequency of 15 rice-based processed foods showed that the use of rice cookies and breads, instead of wheat, was highly correlated to another 13 foods. The critical reasons why they do not consume cooked rice and rice flour were uncertainty of the purity of the rice and the addition of preservatives, and that with rice bread and noodles there was no information available about the products, and hey have a poor taste. The most common reasons of using cooked rice were no time to cook and simple curiosity about the products. However, the consumers were suspicious of containers, which were a potential cause of environmental hormones, and the high price of the products. Packed rice flour was mainly used as an ingredient to give the viscosity to a product. The advantages of using rice flour were that it was available to control the amount of buying and the convenience to buy. However, it was pointed out that the taste of products containing packed rice flour were poorer than that of rice flour ground at a mill.

  • Purpose: The purpose of this study was to identify the influence of nursing organization culture on resilience of new nurses. Methods: Participants were 1,033 new nurses with careers of less than 12 months and who were from 43 general hospitals located in Seoul, Incheon, other metropolitan cities and provinces in Korea. The data were analyzed using t-test, ANOVA, Pearson correlation coefficient and multiple regression with SPSS/WIN 24.0 program. Results: Relation-oriented culture was scored highest for perception of organizational culture by new nurses (3.35), followed by hierarchy-oriented culture (3.19), innovation-oriented culture (3.12), and task-oriented culture (2.73). The score for resilience of the new nurses was 3.49, and the first subcategories were interpersonal relationship ability 3.66, self-positivity 3.45, and self-control ability 3.36. Relation-oriented culture (${\beta}=.30$, p<.001) was the most significant factor influencing resilience of new nurses, followed by innovation-oriented culture (${\beta}=.14$, p=.001), hierarchy-oriented culture (${\beta}=.12$, p<.001), task-oriented culture (${\beta}=-.10$, p=.003) in that order ($R^2(adj. R^2)=.16$, F=47.04, p<.001). Conclusion: Findings show that for improved resilience in new nurses it is necessary to develop relation-oriented culture to provide a cooperative work environment(friendly interpersonal relation and dialogue) for new nurses and to encourage involvement of these members in the hospital culture.

  • Objectives: The purpose of this study was to explore the effects of injection laryngoplasty (IL) with hyaluronic acid in patients with vocal fold paralysis (VFP). Methods: A total of 50 patients with VFP participated in this study. Pre- and post-IL assessments were performed, which included analyzing the sustained vowel /a/ phonation, and the patient reading 1 Korean sentence from the "Walk" passage that comprised 25 syllables in 10 words. To investigate the effect of IL on vocal fold function, acoustic analysis (acoustic voice quality index, cepstral peak prominence, maximum phonation time, speaking fundamental frequency) was conducted and auditory-perceptual (grade and overall severity), visual judgment (gap), and self-questionnaire (voice handicap index-10) assessments were performed. Results: The patients with VFP showed statistically significant differences between pre-and post-IL assessments for acoustic and auditory-perception, visual judgment, and self-questionnaire assessments. Conclusion: The patients with VFP showed positive change in vocal fold function between pre- and post-IL measurements. The findings showed that IL with hyaluronic acid is an effective method to improve vocal fold function in patients with VFP.
