Due to recent climate change, increased traffic volume, and the aging of road infrastructure, the occurrence of potholes has been on the rise, posing significant risks to driver safety and vehicle operation. Accordingly, the importance of technologies that can detect and repair potholes quickly and accurately is gaining attention, as they are recognized as a key task for ensuring traffic safety and improving the efficiency of road maintenance. Conventional pothole detection technologies have evolved based on vibration sensors, laser measurement, and image recognition; however, most of them are limited to detecting the mere presence of potholes without providing quantitative information on their depth or risk level. To address this issue, this paper proposes a deep learning-based real-time pothole detection system that combines YOLOv5-based pothole detection with a depth estimation model. Furthermore, by utilizing a Large Language Model(LLM) to generate user-friendly warning messages and delivering them via voice guidance, the system enables drivers to immediately recognize dangers without relying on visual information.

티몬․위메프 사태의 재무관리적 분석: 유동성 관리 실패와 도덕적 해이

이지윤 한국재무관리학회 2024 재무관리연구 Vol.41 No.5

본 연구는 최근 이커머스 업계에서 발생한 대규모 미정산 사태인 티몬․위메프 사건을 재무관리적 관점에서 분석하고 그 대책을 모색한다. 본 사태의 주요 원인으로 유동성 관리 실패와 경영진의 도덕적 해이를 제시한다. 이러한 문제는 이커머스 업계만의 특수한 문제가 아니기 때문에 대책의 마련에 있어 이커머스 업계 전반에 대한 규제 강화보다는 재무관리적 접근이 효율적일 것임을 강조한다. 유동성 관리 실패로 인한 피해 확산 및 도덕적 해이 문제를 방지하기 위한 대책을 제안하나, 규제는 재무 건정성이 취약한 곳에 집중할 것을 권장한다. 본 연구는 이커머스 업계의 신뢰성 확보를 위한 규제가 필요할 수 있으나 업계의 혁신을 저해하지 않는 유연한 경영 환경 마련의 필요성을 강조하며, 해외 기반 이커머스 기업에 대한 법적 책임 문제에도 주의를 기울여야 함을 지적한다.

Objectives This study aims to analyze the current state of educational research related to the Socratic Dialogue method, particularly in the context of the upcoming implementation of the revised 2022 curriculum. Methods The study involved analyzing 130 scholarly articles and thesis related to the Socratic method in education, published between 2015 and December 2022. Initially, the research classified by the types of studies according to school grades and research methods to analyze their current state. For a more comprehensive analysis, the study further categorized research types based on content, examining the status of applied subjects, research topics, and the use of literature and models. Results Firstly, the research types were predominantly literature studies. In particular, literature studies were prevalent in joint or elementary and high school-targeted research, while quantitative studies were common for early childhood and qualitative studies for middle school. Secondly, out of 130 studies related to the Socratic method, 72 were classified as basic research, mainly focusing on ‘general education’ and ‘moral’ subjects. In practical research, ‘moral’ and ‘philosophy’ subjects were commonly applied, especially ‘philosophical (community of inquiry activities)’ for early childhood education. Thirdly, upon reviewing the literature and models used in the research, basic research most frequently utilized ‘Dialogues’, focusing on educational implications like ‘teaching methods’⋅’teacher's role’⋅‘educational objectives’⋅‘content’. They emphasized educational objectives such as ‘truth-seeking’⋅‘knowledge’⋅‘unity of knowledge and action’⋅‘wisdom’, using key concepts from the ‘Dialogues’ and frequently analyzing the Elenchos method of Socratic dialogue. In practical research, over 50% reported results from conducting philosophical inquiry community activities. Conclusions This study is significant as it reviews the current state of educational research related to the Socratic method since the 2015 curriculum revision, in anticipation of the implementation of the revised 2022 curriculum (in 2024). It provides foundational research material for the qualitative improvement of subsequent studies and suggests future directions.

Purpose This study evaluates the Korean Cancer Study Group Geriatric Score-7 (KG-7) frailty screening tool’s effectiveness in elderly multiple myeloma (MM) patients to prevent under and overtreatment. Materials and Methods This prospective pilot cohort study included 100 elderly patients aged 70 and older with newly diagnosed MM who had not undergone transplantation from August 2020 to January 2022. Results The median age was 77 years, and 73.0% of patients were classified at International Staging System stages 2 or 3. Using a 5-point cutoff on the KG-7 index (non-frail, score ≥ 5; frail, score < 5), 31% were categorized as frail. After a median follow-up of 26.8 months, the 3-year overall survival rate was 73.0%. There was no statistically significant association between any frailty index and the risk of death. However, frail patients defined by the simplified frailty index (hazard ratio [HR], 2.49; 95% confidence interval [CI], 1.09 to 5.95; p=0.030) and by KG-7 (HR, 2.43; 95% CI, 1.03 to 5.86; p=0.043) had a significantly higher risk of grade 3-4 non-hematologic toxicity, whereas the International Myeloma Working Group definition did not. Over a 24-month tracking period, vulnerability as measured by KG-7 either improved or deteriorated. Conclusion The pilot study, which had a limited number of participants, did not demonstrate KG-7’s effectiveness in predicting survival; however, it successfully predicted severe non-hematologic toxicities. We plan to conduct larger studies in elderly MM patients to determine whether KG-7 can help tailor their treatment regimens.

This study examined teacher and child perceptions about teacher attitude and child behavior problems with children who were identified as being at risk for behavior problems by their homeroom teachers. By comparing the teacher and child perceptions regarding each other's attitudes and behaviors and examining the nature and extent of their relationship, the present study proposed to investigate the nature of teacher and child perceptions. It also aimed to exam ine whether perceptual gap in the teacher-child relationship may be a potential risk factor for child behavior problems. A total of 239 subjects(N=239) including 172 children (n=I72) in the 3rd, 4th, 5th, and 6th grade and their homeroom teachers (n=67) participated in the study. Findings indicated that teacher and child perceptions about teacher attitude and child behavior problems showed statistically significant differences, Age specific findings suggested that the interpersonal perceptions are moderated by individual characteristics. Teacher and child reports of the child behavior problems (externalized & internalized behavior problems and overall emotional symptoms) also showed statistically significant differences while the relationship between child reports of teacher attitude and the child behavior problems did not. The greater the difference in the child and teacher perception regarding teacher attitude, the more increased were the child emotional symptoms. Gender and age specific findings added to the complexity of the nature of perceived child behavior problems and its relationship with perceived teacher attitude.

향기 제품의 브랜드 네임이 제품 선호도에 미치는 영향: 흥미의 매개효과 및 제품유형의 조절효과를 중심으로

이지윤,박지환 한국상품학회 2014 商品學硏究 Vol.32 No.6

본 연구에서는 첫째, 향기 제품의 브랜드 네임 유형이 제품 선호도에 미치는 영향을 살펴보고, 둘째, 애매모호한 브랜드 네임과 제품 선호도 간 흥 미의 매개효과를 검증하고, 셋째, 브랜드 네임 유형과 제품 선호도 간 제품유형의 조절효과를 검증하고자 한다. 본 연구목적의 달성을 위해 2(브랜드 네임의 유형 : 애매모호한 브랜드 네임 vs. 명확한 브랜드 네임) x 2(제품유형 : 쾌락제품 vs. 실용제품), 집단 간 변인(between subject factor)으로 설 계하였고, 이에 부합하는 설문지를 통해 K대학교 대학생 총 147명(남70명, 여77명)을 대상으로 자료를 수집하였다. 분석결과, 향기 제품의 명확한 브랜드 네임 보다 애매모호한 브랜드 네임에서 소비자의 제품 선호도가 높게 나타나 가설 1은 지지되었다. 둘째, 향기 제품의 애매모호한 브랜드 네임이 제품 선호도에 영향을 미치는 과정에서 흥미가 매개한다는 것을 검증하였다. 셋째, 실용제품은 브랜드 네임 의 유형에 따른 제품 선호도의 차이가 나타나지 않은 반면에, 쾌락제품은 명확한 네임보다 애매모호한 네임에서 더 높은 제품 선호도를 나타냈다. 따라서 향기 제품의 브랜드 네임 유형과 제품 선호도 간의 관계에서 제품유형은 조절효과가 있는 것으로 확인되었다. 본 연구는 향기 제품에 대해 소비자가 향기를 직접 맡아보지 못하는 경우, 브랜드 네임이 단서적인 정보역할을 할 수 있다는 것을 실증하였다는 점에서 학술적 의미가 있다. 실무적으로 본 연구는 마케터나 또는 브랜드 관리자에게 향기 제품에 대해서 브랜드 네이밍을 할 경우, 제품의 유형을 함께 고려할 필요가 있다는 시사점을 제공한다. 향기 제품의 브랜드 네임 유형이 제품 선호도에 영향을 미치는 과정에서 개인차 변수를 포함한 다양 한 조절변수에 대한 탐색이 필요하고, 아울러 본 연구는 향기 제품 범주에 음료제품만 포함시켰는데, 추후에는 보다 다양한 제품들을 대상으로 재검 증해 볼 필요가 있을 것이다. 본 연구는 Miller and Kahn (2005)이 제시한 브랜드 네임의 분류 기준에 입각해서 브랜드 네임의 유형을 나누고 이를 선 행연구(브랜드 네임을 맛이나 색상표현 적용)와 달리 향기 제품에 적용하여 제품 선호도에 미치는 효과를 실증하였다는 점에서 차별점을 갖는다. 아울러 애매모호한 브랜드 네임과 제품 선호도 간의 관계에서 흥미의 매개효과를 검증하였다는 점이다. This study aims to investigate effects of brand name of scented products on product preference. In addition, we attempt to verify the mediating effect of interest on the relationships between ambiguous brand name and product preference as well as the moderating effect of product types between brand name types of scented products and consumer's product preference. we randomly assigned 147 consumers(male: 70, female: 77) to one of four conditions following a 2(brand name types: ambiguous brand name vs. common descriptive brand name) x 2(product types: utilitarian product vs. hedonic product) between subject design. To test hypotheses in our study, a total of 147 individuals of data was collected by K-university students. Data were collected using a questionnaire and processed with program SPSS. The results of this study are summarized as follows. First, the product preference of consumers was greater for ambiguous brand name than for common descriptive brand name of scented product. Second, interest have turned out to have a full mediation effect on the relationship between ambiguous brand name and product preference. Third, the results of examining the effects of the interaction between product types(utilitarian product vs. hedonic product) and brand name types(ambiguous brand name vs. common descriptive brand name) showed that, with hedonic product, consumers' product preference was greater for ambiguous brand name than for common descriptive brand name. This study is theoretically meaningful in presenting the effects of brand name types of scented products on product preference when it is very difficult for the consumer himself/herself to smell scented products. Practically, this study suggests some useful implications for marketers and brand managers. Nevertheless, this study did not test moderators except for product types. Future study to test diverse moderating variables including individual variables in the relationship between brand name types and product preference will be promising. This study has made contributions to the literature on the relationship between brand name types and product preference in that this study has extended the prior studies by measuring effects of brand name of scented products on customer's product preference. In addition, mediating effect of interest between ambiguous brand name and product preference was verified.

수면 오지각이 불면증 심각도에 미치는 영향: 우울의 매개 효과

이지윤,주은연,최수정,서수연 대한수면연구학회 2020 Journal of sleep medicine Vol.17 No.2

Objectives: Sleep misperception is the underestimation of perceived total sleep time compared to actual total sleep time. It is observed in approximately 50% of patients with insomnia. Insomnia patients with sleep misperception report significantly higher depression than those without sleep misperception. Depression is one of the most consistent risk factors for predicting insomnia. Therefore, this study attempted to confirm the mediating effect of depression in exacerbating insomnia. Methods: This study included 77 male and female aged 18–40 years who met diagnostic criteria for insomnia disorder based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Depression and insomnia severity were measured using self-report questionnaires, and actigraphy data were collected for 1 week. The sleep misperception index was calculated using the sleep diary and actigraphy. Results: The Pearson correlation analysis was performed to examine the relationships between sleep misperception, insomnia, and depression. Sleep misperception was positively associated with depression (r=0.399, p<0.01). There was also a significant positive correlation between depression and insomnia severity (r=0.591, p<0.01). However, there was no significant correlation between sleep misperception and insomnia severity (r=0.210, p=0.07). Depression was found to have a full mediating effect on the relationship between sleep disturbance and severity of insomnia (n=77, B=6.1688, 95% confidence interval=2.9960, 10.4562). Conclusions: This study verified the mediating effect of depression on the relationship between sleep misperception and insomnia severity. The results highlight the importance of considering depression and sleep misperception in insomnia treatment.
