Purpose : The purpose of this study was to know the relationship of stress and aggression of children with physical disability. The study also tried to search the factors affecting aggression and offer the information to the department of occupational therapy for intervention. Method : We distributed questionnaire to 105 children who have disability grades from hospitals in Gyeongsangbukdo, Gyeongsangnamdo, Daegu, and Busan and collected the data. We used descriptives for analysis of general characteristics, t-test and one-way ANOVA for stress and aggression according to characteristics, and Pearson correlation coefficient and stepwise regression for stress and aggression. Result : The first, stress score was 2.65, aggression was 2.53, and physical aggression was 3.01 that is the highest score in the items. The second, there was a significant difference of physical aggression(p=.021) in comparison of the grades. There was a significant difference of stress(p=.048), total aggression(p=.040), and physical aggression(p=.047) in comparison of gender. There was significant difference of stress(p=.035) and total aggression(p=.042) in satisfaction of school. The third, there was a significant correlation of total aggression(r=.475), physical aggression(r=.568), language aggression(r=.311), anger(r=.397), and hostility (r=.491) quantitatively in correlation of stress and aggression. The fourth, the factors affecting aggression of children with physical disability were stress, male, and satisfaction of school(F=61.187, p<.01). Conclusion : We knew that factors affecting aggression of children with physical disability were their stress and some of general characteristics.

The purpose of this study was to verify the impact of cognitive and emotional factors on artificial intelligence speakers on the intention of using artificial intelligence speakers. The method for this study was online surveys of people with physical disability. The recognition and necessity of artificial intelligence speakers were also identified, the perceived intimacy, joy, and intention to use them, and a multiple linear regression analysis was conducted to check the influence of each variable on the intention of the disabled to use artificial intelligence speakers. This study have shown that the perceived enjoyment of AI speakers in people with disabilities has shown a significant static effect on their intended use. However, the recognition and necessity of artificial intelligence speakers of the physically handicapped, as well as the perceived intimacy, do not have a statistically significant impact on the intention of using artificial intelligence speakers, according to the analysis. The results of this study suggest that it is necessary to strengthen the elements of enjoyment in order to improve the intention of the disabled to use artificial intelligence speakers, and it is meaningful in that it provides basic data to develop artificial intelligence products and customized services for people with disabilities.

생산일정계획 수립 시스템을 통하여 수립된 생산계획을 현장에서 실천하고자 할 때, 일반적으로 계획수립 후 얼마 지나지 않아 계획수립시 고려할 수 없었던 기계고장 또는 자재조달 지연, 작업 지체, 주문 취소 등과 같은 요인으로 생산일정을 계획대로 실천할 수 없는 경우가 발생한다. 이런 상황에서는 기존의 생산계획을 계속 실행할 수 없으므로 손쉽게 대처할 수 있는 방안이 필요하다. 본 연구에서는 일정계획편집기를 이러한 문제점을 해결할 수 있는 대안으로 제시한다. 일정계획편집기를 GUI, 객체지향적 설계를 통해 구현하므로서 이상상황과 일정변동에 효과적으로 대처할 수 있다. GUI환경을 통해, 수립된 생산일정과 이상상황, 작업진척, 수행도 등을 화면에 Gantt 도표로 표시해 주어 현장 파악을 용이하게 하고 작업추가, 삭제, 작업시간 변경, 대체공정으로의 이동 등의 편집을 mouse와 icon을 이용, 편리하게 수행할 수 있다. 편집작업시 자동으로 생산일정의 타당성을 만족시켜 줄 수 있는 지능화를 위한 기초 단계로서 객체지향설계를 이용한 규칙기반 일정계획 편집기를 설계한다.

Alternative computer access devices are one of the ways for the physically disabled to meet their desire to participate in social activities. Most of these devices provide access to computers by using their feet or heads. However, it is not easy to control the mouse by using their feet, head, etc. with physical disabilities. In this paper, we propose a computer access system for the physically disabled. The proposed system can move the mouse only by the user's gaze using the eye-tracking technology. The mouse can be clicked through the external button which is relatively easy to press, and the character can be inputted easily and quickly through the voice recognition. It also provides detailed functions such as mouse right-click, double-click, drag function, on-screen keyboard function, internet function, scroll function, etc.

Work zone traffic control is of keen interest because both traffic operations and safety performances are directly affected by traffic management methods. In particular, work zone traffic on two-lane roads needs to be managed in more efficient and safer manners due to its unique characteristics of alternative right-of-way assignment. This study developed a dynamic control algorithm that can be used for real-time operations of two-lane work zone traffic. The performance of the developed algorithm was evaluated by VISSIM microscopic traffic simulator. An applied programming interface (API) based program was developed to plug-in the control algorithm onto the simulator. The results demonstrated the feasibility of the proposed control algorithm for two-lane work zone.

현장에서는 주공정과 예산관리를 중심으로 공사진행을 하고, 공정이 90% 이상 달성되었거나 또는 잔여공기가 9개윌 정도 남아 있으면 모든 공정을 재검토하기 바란다. 우선 하청시로부터 잔여 공사에 대한 공정표를 받아, 잔여공시 1개월 전에 준공될 수 있는지 검토한다. 9개월 정도 앞서 준공기일을 검토하는 것은, 자재납기가 장기간(7개월 정도) 소요되는(플랜트 Control Panel 등) 자재의 발주여부를 검토하고, 잔여공기 내에 정상 작업으로 공기 내 준공이 불가하다고 예측될 경우, 3개월 또는 6개월 돌관작업 계획을 세우기 위함이다. 잔여공기가 3개월 정도 남아 있을 때, 시설물을 인계(Hand Over) 하기 위해 본격적인 준비를 한다. 준공이란 "계약적으로 발주자가 실제적으로 계약서에 의도된 목적으로 사용할 수 있는 상태(표준계악일반조건 48. 1)"를 말하므로, 이 점에 착안하여 발주자가 시설물을 제때에 사용하지 못함으로써 발생되는 지체보상금(Liquidated Damage)을 물지 않도록 작전을 세운다.

Delay schedule coming about duration extension is happening essentially because public construction project consist of many sub contractor. The method which can calculate delay day is suggested by many studies in case of happing delay schedule, but It is difficult to apply to real construction project because there is no mention about the control of The law of contract according to delay schedule. The law of Contract which is cost of account has more uncertain problem than FIDIC condition of contract. This study suggests method which can make extension of duration procedure clear in case of happing the reason of design change related with activity duration during carrying on construction, and a submission process of the reason of duration extension and modify schedule making way about section which is basis of calculating contract amount clear.

Many people with disabilities have shown interest in artificial intelligence speakers that serves as the main hub of the smart home. Therefore, the purpose of this study was to identify the intention of people with disabilities to use such speakers. The focus is on those with physical disabilities, a segment that accounts for the largest number of disability types. Based on the theoretical model of technology acceptance, the effect of perceived ease of use and perceived usefulness of artificial intelligence speakers by people with disabilities was analyzed using Structural Equation Modeling (SEM). Research has confirmed that the technology acceptance model is suitable for identifying the intention to use artificial intelligence speakers by people with disabilities, and specifically that the perceived ease of use has a significant impact on usefulness. Furthermore, the perceived ease of use for people with disabilities did not have a statistically significant effect on their intent to use whereas the perceived usefulness was shown to have a significant effect on the same. This study is meaningful as a foundation for developing customized artificial intelligence speaker services and improving the use of artificial intelligence speakers by people with disabilities.

신호교차로의 서비스수준은 미국의 HCM 방식을 전세계적으로 준용하고 있으며, 우리나라도 1985년 미국 HCM을 기본으로 하여 우리나라의 특성을 반영한 보정계수 값들을 수정하여 지금까지 사용하고 있는 것이 현실이다. 하지만 한국 도로용량편람의 모태가 된 미국 HCM은 이미 94년 1차 수정판에 이어, 이를 더욱 보완해서 HCM 2000을 발간하여 실용화 단계에 있는 반면 92년에 발간된 한국도로용량편람은 발간 이후 빠른 속도로 변화해온 국내의 교통, 도로, 차량 특성과 다양해진 도로시설 유형의 변화를 신호교차로 서비스수준 분석에 적절히 반영하지 못하고 있다. 이에 본 연구는 신호교차로 서비스수준 결정에 관한 연구의 기초작업으로 기존의 신호교차로 서비스수준 분석방법의 문제점을 보완하기 위한 새로운 분석방법론을 제시하였다. 이를 위해 한국 도로용량 편람과 미국 HCM 2000의 서비스수준 분석방법론 부분을 면밀히 비교 분석하고 두 나라의 지체식에 포함된 공통적인 변수(주기(C), 포화도(v/c), 용량(c), 녹색시간비(g/C))에 대한 민감도 분석과 미국 HCM 2000에 추가로 도입된 변수들에 대한 민감도 분석을 수행함으로서 한국 도로용량 편람의 문제점을 고찰하고 운전자의 행태나 도로의 기하조건이 외국의 경우와는 다른 우리나라 실정을 반영한 한국형 신호 교차로 서비스수준 정립 방안의 필요성을 제시하였다.
