License Plate Detection (LPD) is a key component in automatic license plate recognition system. Despite the success of License Plate Recognition (LPR) methods in the past decades, the problem is quite a challenge due to the diversity of plate formats and multiform outdoor illumination conditions during image acquisition. This paper aims at automatical detection of car license plates via image processing techniques. In this paper, we proposed a real-time and robust method for license plate detection using Heuristic Energy Map(HEM). In the vehicle image, the region of license plate contains many components or edges. We obtain the edge energy values of an image by using the box filter and search for the license plate region with high energy values. Using this energy value information or Heuristic Energy Map(HEM), we can easily detect the license plate region from vehicle image with a very high possibilities. The proposed method consists two main steps: Region of Interest (ROI) Detection and License Plate Detection. This method has better performance in speed and accuracy than the most of existing methods used for license plate detection. The proposed method can detect a license plate within 130 milliseconds and its detection rate is 99.2% on a 3.10-GHz Intel Core i3-2100(with 4.00 GB of RAM) personal computer.

The increased diversity in designs, colors, and materials of children's clothing these days call for extra caution in care of these garments; however, the lack of customer's trust and efforts in complying with the care label combined with the enterprises's inadequate label attachments have led to various problems and disputes. This research attempts to examine customer's recognition, perception, and attitude towards the care labels on children's clothing. This research used the data collected from a total of 292 housewives raising children less than 7 year old. Descriptive statistics such as means, standard deviations, frequencies were calculated and ANOVAS followed by Duncan tests were carried out using SPSS 10.0. The results are as follows: First, 84.3% of the housewives admitted that they know about care labels; individuals with higher education level reported higher recognition. Second, as for the perception/attitude toward care labels, 46.9% perceived that care labels 'require additional knowledge for washing clothes' and 30.2% answered that they trust care labels. Third, 51.7% answered that they 'check the symbol instruction'; this tendency was higher among those with higher education levels. Fourth, 31.5% answered they comply with the instructions on care labels. Fifth, as for the reasons for not complying, 60.3% answered they neglect care labels because 'based on my experience, no major problems would occur'; this tendency was higher for those with greater personal income. Sixth, when asked whether any information on the care label kept them from buying a particular garment, 59.2% responded they did not purchase a garment because 'laundry costs appeared to outweigh the product price'; this response was higher among individuals with a higher level of income or education.

The development of personal computers and the Internet led to changes of instructor-student and student-student relationships in design education. New resources of design education with proper materials and tools have to be offered for teaching and learning. The purpose of this research is to develop Basic Graphic Tools(BGTs) on screen that help students to practice the design principles, and to evaluate the BGTs' usability to enhance the credibility of extra tools for online design learning. The BGTs has to be developed to minimize the gap between the online and traditional classroom settings and to maximize the diverse advantage of lecture content driven from technology. Students were given certain design requirements to explore BGTs and a learning guide/performance test after the lecture to evaluate the tools. The test was performed under the e-learning program serviced by C college. This research has presented some encouraging results and raises questions toward future work: how do BGTs impact the feasibility of an online design lecture.

In this paper, we present a hardware structure and new features of a smart antenna BTS (Base Transceiver Station) for CDMA2000 1X system. The proposed smart antenna BTS is a composite system consisting of many subsystems, i.e., array antenna element, frequency up/down converters, AD (Analog-to-Digital) and DA (Digital-to-Analog) converters, spreading/despreading units, convolutional encoder/Viterbi decoder, searcher, tracker, beamformer, calibration unit etc. Through the experimental tests, we found that the desired beam-pattern in both uplink and downlink communications is provided through the calibration procedure. Also it has been confirmed that the adaptive beamforming algorithm adopted to our smart antenna BTS is fast and accurate enough to support 4 fingers to each user. In our experiments, commercial mobile terminals operating PCS (Personal Communication System) band have been used. It has been confirmed that the smart antenna BTS tremendously improves the FER (Frame Error Rate) performance compared to the conventional 2-antenna diversity system.

The present study was performed to evaluate the job training needs of school nutrition teachers in order to enhance their specialty. Three hundred and forty questionnaires were distributed to school nutrition teachers working at primary and high schools in the Gyeongbuk area while 45 were distributed to professors during 2010~2011. Three hundred and two questionnaires from school nutrition teachers and 33 from professors were returned and analyzed. The rate of teachers practicing nutrition education was 54%, and the educational content was obtained mainly from the internet. The top three problems the teachers encountered were 'lack of standardized educational materials', 'inexperience of teaching', and 'insufficiency of expert knowledge'. The teachers recognized 'training program' as the best solution. However, the job training program operated immediately after teachers were appointed scored only 3.03 out of 5.00. Important contents of the training program ranked highly by the teachers were 'development of education materials', 'nutrition counseling', and 'teaching method'. The professors included 'expert knowledge' in their top three contents. Both the teachers and professors agreed to increase the frequency of 'practice' in training methods. Other factors the teachers considered to be important were high quality, diversity, ability of the instructor, training cycle, and the institution in charge. From these results, it can be concluded that efficient job training programs are needed for school nutrition teachers according to the importance of the education contents and training methods. It is therefore suggested that a cooperation committee be composed of an educator, educatee, and related personal in a local education office in order to operate the program.

The objective of this study is to plan a space for senior citizens using digital contents as the measures for securing the cultural diversity by paying attention to culture of senior citizens. For this, this study theoretically examined digital contents as physical/social/psychological aging of senior citizens, space only for senior citizens, and culture of senior citizens. The research method used an in-depth interview. The results of this study are as follows. The senior citizens wanted the new play culture besides cultural programs operated by the existing spaces for senior citizens, and they also showed high preference of digital contents such as personal media and game. Especially, the senior citizens had an expectation that such digital contents would be helpful to smooth communication between family members. Based on such results, this study suggested a digital based culture spaces for senior citizens.

The childbearing process is not only a biological phenomenon of a woman who gives birth to a child but also a sociocultural phenomenon which is reflected on her value, belief in the sociocultural context according to social change and acculturation. The familial relation and sociocultural context in the multigravidas are more complex and intermingled than in the primigravidas. The purpose of this ethnographic research study was to explore the experience of identity from the first trimester of pregnancy to the third trimester of pregnancy in the Korean multigravidas and to understand deeply the perspectives of pregnant women reflected on Korean sociocultural values, beliefs, norms and familial culture. The participants of 10 pregnant women in Seoul, Korea were observed for 10 months from January to October 2000 and interviewed in their homes and comfortable place. Data analysis was accomplished 'line by line method' and significant concepts were classified according to themes, categories, and domains. The results of this study were as follows : The participants experienced 4 categorized subjects : understanding the oneself - mother to be, performing the dual role, drifting the emotion, and living disheartened during pregnancy. The participants were showed universality and diversity pattern in the self understanding process. The universal pattern were 'mother to be' showing maturation, life along family and priority on motherhood between being a mother and a woman. The diverse pattern were taking the dual role in working mothers having the higher self actualized value and personal identity rather than maternal identity, drifting emotion in resigned mothers, and living disheartened in mothers who have two daughters and no son. In conclusion, the Korean multigravidas experienced womanhood as well as motherhood through the self understanding process with familial connections during pregnancy. Therefore it is suggested that if the harmony and the balance between a mother and a woman is accomplished, the woman will lead a healthy and high quality of life. Also, this study sought to confirm the sociocultural factors affecting during pregnancy in the perspectives of the women with children. Therefore, the health care providers have to divert their attention from biomedical perspectives to biocultural perspectives integrating bio-psycho-sociocultural aspects of pregnant women in a clinical setting.

With the spread of Internet, web users express their daily life by articles, pictures and cartons to recollect personal memory or to share their experience. For the easier recollection and sharing process, this paper proposes diverse cartoon generation methods using the landmark lists which represent the behavior and emotional status of the user. From the priority and causality of each landmark, critical landmark is selected for composing the cartoon scenario, which is revised by story ontology. Using similarity between cartoon images and each landmark in the revised scenario, suitable cartoon cut for each landmark is composed. To make cartoon story more diverse, weather, nightscape, supporting character, exaggeration and animation effects are additionally applied. Through example scenarios and usability tests, the diversity of the generated cartoon is verified.

The aim of this study was to categorize and analyze the patterns of the observation type in the experiential learning through the science museum for elementary gifted students in science. Ten science-gifted students were included and analyzed in this study and during experiential learning in the science museum, the participants freely expressed their observation of their own languages and all observations and dialogue were recorded. The results are listed below. The cognitive aspect, especially question and response activity without their personal opinion, was the most frequently used item. Among the affective aspects, item for 'recommendation' was often used. In accordance to observation type, most participants overall observed single object independently of time. Also, participants mostly observed objects visually using qualitative method without manipulation. Therefore verbal interaction through question might have a positive effect on frequency and diversity of observation. Project learning, such as particular exhibition hall, exploratory time of concentration by students, or study paper will be capable of creating a effective observation learning in order to induce a variety of observation of science gifted students in the experiential learning through the science museum.

A station is not only the public space where socially diverse classes get together and cultural interchanges occur but also the personal and emotional space where the meeting and parting occur for each individual. Thus, it is necessity to consider this dual point from the beginning of the plan to make the simple, comfortable, intuitive and friendly environment for the users in the station. Also, it should be capable of active life style of moderner according to the change of the city environment. Furthermore, as a station is not just a single-purpose space anymore but the versatile space where fulfills the user's needs for the multi-function and the desire for diversity. As the station in these days opened 24 hours for users with the modern, commercial and cultural facilities, the interior design for a station needs to be designed to be easy to use, functional and able to vitalize the environment. In order to make a desirable interior environment in a station, first of all, it is required to grasp the characteristic of the space by analyzing the phenomena of an individual or a group act in a existing space formed by the interrelation between the human and the environment. To reduce the resistance against the new environment from the user, in other words, to increase the satisfaction, it is necessity to induce the behavior of the users to the desirable way toward to the new environment. Consequently, positive methodology with recognitive approach through cognitive psychology, spatial behavior research is required.
