The needs for ecological engineering, which can design ecosystems that integrate human society and their natural environment for the benefit of both, has increased. The Korean Society of Ecology and Infrastructure Engineering (KSEIE) was established for this purpose and has contributed to the research and development of theories and technologies in related fields. However, the current state of educational services and contents of ecological engineering is still needed to be standardized and systematized. In this paper, we outlined the trends of ecological engineering education at international and domestic levels and proposed a sample services and curriculum, brought from the discussions and suggestions made during the forum, Founding the Education for Ecological Engineering, held by the KSEIE. Education of ecological engineering can nurture people who can design and manage ecosystems for the benefits of human and natural society and can restore ecosystems disturbed artificially. The services and curriculum have to meet and cover the challenges facing the future of ecological engineering; a. the ethical interpretation of the balance between human and nature, b. developing and strengthening its relationship with other scientific disciplines and societies - business, policy, education, and practitioners, c. identify and fuse the key ecological engineering principles into other discipline. We proposed a three layers curriculum system, basic (mathematics, physics, chemistry, biology, etc.), core (ecology, hydrology, engineering, etc.), and advanced subjects. The first two can belong to an undergraduate program and the last two can be put into graduate program. The selection of subjects is according to the purpose and needs of the major.

High temperature heat generated during rifle firing not only degrades the performance of the weapon, but also limits the user's operation. In this study, temperature change of handguard according to firing was measured with reference to Human Engineering criteria and the operability according to material was examined. Accordingly, for the firing test, three types of Korean rifle and one overseas model were selected for each material of handguard, and firing test was conducted using a contact type temperature meter. The test result shows that using a plastic handguard with low thermal conductivity and aluminum handguard with high thermal conductivity enabled the rifles to be operated with bare hands even when firing at more than 100 rounds at low atmospheric temperature. However, when firing more than 60 rounds at over 20℃ atmospheric temperature, aluminum handguard use is limited. When firing quickly over 100 rounds, handguard use is restricted regardless of its fabrication material. To eliminate operational limitations by overheating, it is necessary to eliminate direct contact with skin using gloves, vertical grips, etc. This study examined the operability of rifles in terms of thermal risk, and the resulting study results are expected to be used as basic data for Human Engineering of other rifles and munitions.

Rapid urbanization causes a variety of transportation problems, including traffic delay. Then transportation engineers would get involved in trying to solve traffic delay through road constructed and uncongested policy. But lately, traffic policy changed from vehicle-dominated to humandominated and green transportation. Road diet is one of green transportation. Road diets reduce the number of lanes, lane width because supplement space for green transportation including a bicycle road, side-walk, etc. A study on road diets not enough then this study performed a basic study for road diets. This study on lane width reduce for road diets through analyzes sway of moving vehicle. This study results shows lane width of a compacts-size car needs 2.34~2.70m and lane width of a full-size car needs 2.62~2.89m. According to this study lane width can reduce therefore lane width design criterion have to be relieved. This study will be used in a road width reduce including a road diets, road in process of construction and so on.

The purpose of this study is to verify the anthropomorphic design factors of pedagogical agents that can enhance user experience in learning foreign languages (English) through smartphones. In this study, when designing a pedagogical agent that delivers content, the presence or absence of the agent's image, the degree of human nature (HN), and role setting (leader vs. companion) among the anthropomorphic factors that influence facilitating learning, credibility, and engagement perception. As a result of the experiment, HN alone did not show a facilitating learning effect, and images and roles improved not only the facilitating learning effect but also other user experience factors. When HN factors were designed in combination with image and role factors, they were effective in overall user experience effects such as facilitating learning, credibility, and engagement.

Throughout its short history, the discourses of philosophy of technology has been centered around two issues, namely the recovery of human autonomy in technological society and the pursuit of sustainable development. Following the basic subject matters of the discipline, this article suggests to examine the possibility of the 'ethical engineering design,' meaning that ethical consideration should be included in engineering design. This proposal is based on the critique that philosophy of technology has so far focused on the external approach to the problem of technology, neglecting the active role of engineers. By paying attention to engineering design, however, philosophy of technology can offer a more realistic solution for the problems of the technological society. The first section shows the context of the current discussion by surveying the brief history of philosophy of technology. The thesis of engineering design in philosophy of technology will be presented in the second section, together with supporting reasons. The third section will examine theories and efforts that raised the issue of engineering design in the past. They have been suggested in different contexts, but when put together, they can be used for the justification of the current proposal. The fourth section will deal with the possible critiques of this proposal, which will be followed by suggestions for engineers themselves.

In this study, the optimal position for the backrest pivot of an office chair was investigated by evaluating its performance in terms of the lumbar support and sliding distance of the back from the backrest during tilting motions. The simulation was performed using a mathematical model, which included a human body and a chair. Forty-two backrest pivot points were selected on the sagittal plane around the hip joint of a sitting model. A motion analysis study was also performed using a prototype of an office chair (A-type) with a backrest pivot located on the hip joint of a normal Korean model and a typical office chair (B-type) with its pivot located under the seat. The simulation results showed that both the lordosis angle and the slide distance of the back were minimized when the backrest pivot was positioned close to the hip joint. The experimental results showed that the slide distance and gap between the sitter's lumbar and the backrest was smaller with the A-type than the B-type. Based on the simulation and experimental results, it can be concluded that the backrest can support the sitter's lumbar area more effectively as the pivot position for reclining approaches closer to the hip joint. In this position, the sitter can maintain a comfortable and healthy sitting posture. This paper presents the methods and guidelines for designing an office chair with ergonomic considerations.

유비쿼터스 컴퓨팅 환경은 오늘날 인간생활 행태의 변화뿐만 아니라 미래건축 공간에도 큰 변화를 가져오고 있다. 그 중에서도 인간의 가장 기본적인 생활환경인 주거 공간의 변화는 빠르게 이루어지고 있다. 지능형 홈, 사이버 아파트 등의 새로운 미래주거 공간이 나타나고 홈네트워크 시스템을 이용한 다양한 유비쿼터스 서비스가 적용되고 있다. 그러나 거주자를 위한 유비쿼터스 서비스가 공간에 적절히 적용되지 않는 사례가 발생하고 있고 수요자 요구와 관련 없이 서비스가 설계되어 있어 효율성이 떨어지는 문제점도 나타나고 있다. 이는 현재의 홈네트워크가 IT 업계가 제공한 솔루션과 기기 중심으로 서비스가 개발되고, 공급자 위주의 기능의 편리성을 위주로 제공되고 있기 때문이며, 주택을 잘 알고 있는 건설인과의 협업이나 최종 사용자의 기호가 고려되고 있지 않기 때문이다. 더욱 중요한 것은 초기 디자인 단계에서 이러한 문제점들이 수용되고 있지 못하고 공간 디자인과 서비스 개발이 유리화되어 선 시공 후, 서비스를 끼워 맞추기식으로 계획하고 있기 때문이다. 본 연구는 서비스 개발의 관점에서 접근하여 공동 주택의 초기 디자인 단계에서 수요자가 원하는 서비스를 공간에 적용하여 부합되는지를 살펴보고, 이에 따라 적절한 미래공간을 디자인 할 수 있도록 하기 위하여 공간정보 데이터베이스를 기반으로 한 공동주택 유비쿼터스 서비스 개발을 위한 기초 연구에 그 목적을 둔다.

As menu structure of household appliance is complicated, user's cognitive workload frequently occurs errors. In existing studies, errors didn't present that interpretation for cognitive factors and alternatives, but are only considered as statistical frequency. Therefore, error classification and analysis in tasks is inevitable in usability evaluation. This study classified human error throughout information process model and navigation behavior. Human error is defined as incorrect decision and behavior reducing performance. And navigation is defined as unrelated behavior with target item searching. We searched and analyzed human errors and its causes as a case study, using mobile phone which could control appliances in near future. In this study, semantic problems in menu structure were elicited by SAT. Scenarios were constructed by those. Error analysis tests were performed twice to search and analyze errors. In 1st prototype test, we searched errors occurred in process of each scenario. Menu structure was revised to be based on results of error analysis. Henceforth, 2nd Prototype test was performed to compare with 1st. Error analysis method could detect not only mistakes, problems occurred by semantic structure, but also slips by physical structure. These results can be applied to analyze cognitive causes of human errors and to solve their problems in menu structure of electronic products.
