This study was to identify HCl design factors for increasing information processing and attention for mentally retarded children. Several factors such as size, location, moving distance were varied for three experiments operated by the amount of information. The results showed that the larger size of target, the greater moving distance of target, and the less amount of information increased mentally retarded children's sensitivity. Also, when the target was displayed at upper left of computer screen, sensitivity of mentally retarded children was high, compared other locations of screen.

Recently, the status of public education has fallen and instead, the fever of private education has caused various social problem. Because of this private education, the polarization of education has become more serious. Under this circumstances, this study has focused on the effect of NIE (Newspaper in Education) which is expected to bring about some positive educational results. In foreign countries such as North America and European countries, NIE has already been introduced to schools. The educational effects of NIE has also been recognized. Korea also accepted NIE and expect positive educational effects. Therefore, the experimental study has been performed to prove the educational effect of NIE. Both for the middle school students and high school students, experimental group and control group were divided. After that, with the same study plan, experimental group studied with NIE method and control group studied with regular method. The results revealed that NIE method was effective to raise test scores. However, the subject interest and study attitude were not found to be related with the study methods. Implications were discussed.

In spite of increasing women migrants, proper social programs based on human rights are hardly found. In this paper, with the implication of 'diaspora', the essential term of multi-culturalism from the perspective of migrant women is briefly discussed. Also, social programs for migrant women are suggested through looking into the experiences of EU. EU policies and social programs are reorganized through data analysis and policy contents analysis. EU has longer history of immigration, and has provided the proper and long-term programs to accept migrant women as the qualified social member. EU social programs are based on the principles of non-discrimination, full employment, human rights and citizenship. Social programs should imply long-term inclusive policy for migrants, and help migrants to experience empowerment in the society. By looking into some examples of social programs of employment, education and general knowledge, useful social programs are to be suggested.

감성(sensitibility)은 반사적이며 직관적으로 발생하고, 인위적인 조정이 불가능하며 명확한 표현이 어렵고 모호하다고 한다. 또 감정(emotion)이 주어진 대상에 따라 동일한 반응을 보이는 공통성을 갖지만, 감성은 동일한 대상에도 개인에 따라 다양한 반응을 보이며, 시간과 환경에 따라 변한다고 본다. 이는 반응 형성의 두 가지 요소인 외부의 자극이나 대상과 반응하는 주체의 양자에서, 감정이 감성에 비해 외부의 자극이나 대상의 영향을 더 받고, 감성은 상대적으로 외부 상황보다는 반응 주체의 다양한 내부 상황에 따라 결정된다는 것을 의미할 수 있다. 이러한 감성의 특징들은 Freud가 말한 무의식의 특징과 비슷한 점이 많다. 따라서 무의식의 작용양상을 살펴보는 것이 감성의 연구에 도움이 될 수 있다고 생각한다. 무의식이란 우리의 마음에 항상 작용하고 있지만, 일상적인 상태에서는 분명하게 알아 볼수가 없고 확실하게 드러나지도 않는 어떤 힘을 말한다. 이는 개인의 다양한 과거 경험이 포함되어 있어서 사람에 따라 각기 다르게 나타나게 된다. 우리가 항상 경험하고 있는 의식은 확실하게 서로 구분되는 대상과 확인율(the principle of identity), 구분논리(bivalent logic), 모순율(the principle of formal contradiction), 상반율(the principle of incompatibility), 가감율(the operation of substraction)을 수용하여 작용한다. 무의식은 의식활동의 이러한 명료함과 정연함을 벗어나 활동한다. 대상간의 구분이 모호해지고 정연한 논리가 흐트러진다. 일상에서는 꿈의 내용과 어린이의 생각, 감정에 치우칠 때 무의식의 특징이 나타난다. Freud는 꿈을 관찰하여 무의식의 작용양상을 다음과 같이 설명하였다. 서로 상반되는 것들이 다음과 같이 설명하였다. 서로 상반되는 것들이 부딛힘이 없이 공존하고 일상의 논리가 무시된다. 부정, 의심이 없고 확실한 것이 없다. 한 대상에 가졌던 생각이 다른 대상에 옮겨간다(displacement). 한 대상이 여러 대상이 갖고 있는 의미를 함축하고 있다(condensation). 시각적인 순서가 무시된다. 마음속의 생각과 외부의 실제적인 일을 구분하지 못한다. 시간 상의 순서가 있다가 없다가 한다. 차례로 일어나야 할 일이 동시에 한꺼번에 일어난다. 대상들이 서로 비슷해지고 동시에 있을 수 없는 대상들이 함께 나타난다. 사고의 정상적인 구조가 와해된다. Matte-Blance는 무의식에서는 여러 독립된 대상들간의 구분을 없애며, 주체와 객체를 하나로 보려는 대칭화(symmetrization)의 경향이 있기 때문에 이런 변화가 생긴다고 하였다. 또 대칭화가 진행되면 무한대의 느낌을 갖게 되어, 전지(moniscience), 전능(omnipotence), 무력감(impotence), 이상화(idealization)가 나타난다. 그러나 무의식에 대칭화만 있는 것은 아니며, 의식의 사고양식인 비대칭도 어느 정도 나타나며, 대칭화의 정도에 따라, 대상들이 잘 구분되어 있는 단계, 의식수준의 감정단계, 집단 내에서의 대칭화 단계, 집단간에서의 대칭화 단계, 구분이 없어지는 단계로 구분하였다.

We propose control mechanism of UAV(Unmanned Aerial Vehicle) group for making the communication network to the base station after the target is found. We assume UAVs can communicate to each other by wireless LAN without existing communication infrastructure. UAVs started to fly in linear formation, after finding target, UAVs move to the base station to send the information about the target. At least one UAV stays the position that the target is found. This paper explains the mechanism supporting reliable connectivity during UAV group's flying. We verify the proposed scheme and evaluate the performance through NS-2 simulation. The proposed scheme can be applied to the disaster area and war zone, which the existing communication infrastructure cannot be worked.

This study attempts to identify the problems in applying the deliberative polling method within the Korean cultural context. The deliberative polling method uses information distribution and group discussion to encourage the poll participants to be informed on and deliberate the issues, so that they may express their elaborate informed opinions when surveyed after discussion. One of the criticisms is that having all the poll participants assemble in one location may result in lower level of poll participation and accordingly a less representative sample. Also, the assumption that group discussion will bring about deliberation has not been tested. Some research suggests that in certain Asian cultures, group discussion is not widely used for conflict resolution or consensus building. Thus this study proposes that the mere utilization of a group discussion method does not necessarily imply that the participants have actually deliberated the issues. A telephone survey of one thousand Koreans over the age of 20 was conducted. The survey results show that group discussion is not a common way to discuss controversial issues in Korea, and would contribute to a low participation rate. It is the conclusion of this study that alternative deliberation methods need to be developed.

An automated lifting vehicle(ALV) used in an automated container terminal is a type of unmanned vehicle that can self-lift a container as well as self-transport it to a destination. To operate a fleet of ALVs efficiently, one needs to be able to determine a minimum-time route to a given destination whenever an ALV is to start its transport job. To find a route free from any collision or deadlock, the occupation time of the ALV on each segment of the route should be carefully scheduled to avoid any such hazard. However, it is not easy because not only the travel times of ALVs are uncertain due to traffic condition but also the operation times of cranes en route are not predicted precisely. In this paper, we propose a routing method based on an ant colony optimization algorithm that takes into account these uncertainties. The result of simulation experiment shows that the proposed method can effectively find good routes under uncertainty.

With the rapid spread of smartphones, it has become common to listen to music everywhere, just like background music in life, so it is necessary to create a music database that can make recommendations according to individual circumstances and conditions. This paper proposes a music recommendation model through social media. Since emotions, situations, time of day, weather, etc. are included in hashtags, it is possible to build a social media-based database that reflects the opinions of various people with collective intelligence. We use web crawling to collect and categorize different hashtags from posts with music title hashtags to use real listeners' opinions about music in a database. Data from social media is used to create a music database, and music is classified in a different way from collaborative filtering, which is mainly used by existing music platforms.

People who spend more time alone tend to report higher levels of loneliness. However, whether people experience loneliness in solitude can differ The current research investigated the role of a sense of power as a predictor of loneliness among people who lack social interaction. investigated factors predicting loneliness in people with little social time large-scale survey data. As a result of discriminant analysis, a sense of power was verified as a factor that lonely non-lonely groups. a sense of power As a result, a causal relationship between a sense of power and social loneliness was confirmed. When people feel alone, a high sense of power can work as a buffer against loss of belongingness and the experience of social loneliness. This research focused on psychological rather than situational factors to alleviate loneliness in the current situation where social encounters are limited due to the increase of single-person households and the 19 pandemic.

This study was conducted to design and apply simulation-based problem-based learning classes, and then analyze the effects of class management using focus group interviews. In paramedicine, practical learning that can respond to various emergency situations based on major knowledge is important. In the case of problem-based learning classes, it is suitable for operating various topics covered by the Department of Paramedicine as it can improve capabilities such as problem-solving strategies, skills, and teamwork by providing practicality related to field situations for learning. This study developed a PBL module focusing on patients with dyspnea and applied it to medical emergencies and practice courses taken by 16 third graders of S University's Paramedicine department. Overall class satisfaction was high from 4.76 to 4.92. In particular, by resetting the learning strategy through PBL classes and experiencing cooperative learning, positive learning outcomes could be obtained and self-efficacy was experienced.
