Fast development of ubiquitous technology prompted the broadening of the related application area. Application of ubiquitous techniques and system into the construction sites may give us many benefits. There are always a lot of hazard situations in construction sites, and the falling is known to have the high accident rate. To prevent the falling, there has been a lot of efforts including safety education and use of safety gears. In this study, we designed, fabricated and tested a system that can monitor the worker's safety and location informations in real time by using the wireless technology of TOA and RSSI. We used ATmegal28 that is popular in the industrial equipments as MCU and NanoPan 5357 module from Nanotron and CC2500 chipset from TI for radio circuits. We also used 3-axis accelerometer and pressure MEMS sensors to obtain the environmental information, and therefore to aquire the informations of the worker's movement and altitude. We used Labview software from National Instrument to monitor and control the system. We developed the system to send the warning alarms to the server operator and the workers when the workers in the danger zone did not wear the safety hook.

This study was performed to search for correlation between activity limitation level and participation restriction of children with cerebral palsy by investigating the activity limitation level through the use of the GMFCS E&R and the MACS and by figuring out participation restriction level through questionnaire survey. This study was performed, from May 1, 2010 to August 31, 2010, on 152 children with cerebral palsy ranging from 4 to 12 years, who are receiving rehabilitation therapy in the hospitals and community clinics in Busan and Gyeongnam province. The levels of activity limitation were assessed by using GMFCS E&R and MACS, and a questionnaire survey was conducted for participation restriction of the participating children. Spearman rank correlation was used for correlation analysis with the statistical software, SPSS 12.0. Majority of the children scored level 5 in both GMFCS E&R and MACS which is high frequency of activity limitation levels. Children in these levels also showed severe or complete participation restriction for mobility, education, and social relations. The analysis showed a significantly positive correlation between activity limitation level and participation restriction. Therefore this study may be useful in assessing the functional movement component of participation in children with cerebral palsy and developing the intervention plan for participation.

The purpose of this study is to analyze the effects of target position on the bowling motion. Four female high school athletes with more than four years of bowling experiences were recruited to this study. The major results of this study are as follows; When a subject treats the 1st pin, The spin angle of a coxa for the target position is largely kept from the downswing to the backswing peak point. When a subject treats the 7th pin, As the 7th pin exists at the left side for the right shoulder axis of the thrower, the movement of the ball center of the thrower from side to side is the lowest. In addition, the time required and horizontal speed appear the highest in the release section. The slant angle of a shoulder is largely increased as she moves from the backswing peak point to the release section. The twist angle of a shoulder also appears small as a throw motion is made toward the left side. When a subject treats the 10th pin, The spin angle of a shoulder and the twist angle of a body in motion appear the largest in the release section. So, there are the effects of target position on the bowling motion.

The intent of this paper is to examine the talus in Chon-hwang-san in the southern part of Korean Peninsula, and then analyze its geomorphic feature and origin. The research is summarized as follows; (1) The talus is 220m long and the range of the width from 10 to 75m. The mean gradient is $33^{\circ}$ and the mean block size is $110{\times}59cm$(long axis$\times$short axis). The overall appearance of the talus is tongue-shaped and the geology of the constituent blocks is dacite. (2) This talus has two particular geomorphic landscapes. One is that the talus has not free face as source of blocks back of itself; the free face of the talus has been parallel retreated to disappearance by frost attack. The other is that the upper part of the talus is on the ridge. (3) This talus is classified into rock fall talus type, and the shape of rock fragments is angular. When considered in conjunction with face of being mentioned above, the morphology and lithology of the talus are best explained on the basis of origin under periglacial environment during late pleistocene time. (4) Most constituent rock debris are now lichen-covered, or covered with a mantle of weathering. There is no evidence of appreciable movement and for supplying block. Therefore, the talus appears to be relict or fossil form stage, currently.

This paper has examined the origin of organic fanning, its development stages, its certification program, and its distributional characteristics in South Korea. Organic agriculture in South Korea originated in the late 1970s as several organic farmers' associations started to be formed. However, the certification of organic farm products, based upon the Codex guideline on organic produce as well as the FAO/WHO find standards, was not institutionalized with the year 2001. A majority of organic products are currently certified as farm products grown with low chemical input. Vegetables grown without any chemical input occupy the largest proportion of the certified produce, while fruits take the smallest. The average size of farms practicing organic agriculture is 0.88 hectare, smaller than the scale of conventional farms being 1.39 hectare. These organic farms are concentrated in Gyeonggi, Chungcheongbuk, and Jeju Province, where organic farmers' associations were first founded. The roles of those associations not only in developing and extending organic farming techniques but also in promoting organic agriculture to consumers were most critical in the regional development of organic farming. It would be desirable for local governments to promote organic farming in tandem with a whole environmental movement.

The purpose of this study to provide implications for improvement of Korean voluntary sector, by analyzing of program managers' subjective evaluation of voluntary program management and of their view of the needs for outside supports. For this, researchers selected 600 agencies, which are found to have a staff in charge of voluntary programs, and sent a questionnaire by mail. Those agencies are consisted of the following three. areas: social services, civil movement, public sector. The response rate was 65%, and researchers analyzed 382 respondents out of 391, besides those who did not complete the form in full. One of the results was that program managers' subjective evaluation score of overall voluntary program management was 51 points in the perfect score of 100 points. The voluntary program management was consisted of the following six areas: recruiting, job placement, public relations, education(training), program development, and. information system Specifically, program development and information system appeared to be worse than the other areas, and this fact was true in all three types of agencies of social services, civil movements, and public sector. Moreover, program managers in public sector showed that outside supports for voluntary programs (or activities) was more desperately required. Based on the results, researchers concluded that, toward the improvement of voluntary programs, professionalization as well as legal supporting system, networking, and national supporting institution were required.

The purpose of this study was to examine the effects of rhythmic auditory stimulation (RAS) on gait parameters, with and without the presence of a melody, for adolescents with traumatic brain injury (TBI). Three adolescents with TBI received a total of ten individual RAS training sessions. At pre and posttest, spatiotemporal parameters including cadence, velocity and kinematic parameters were measured using the VICON 370 Motion Analysis System. The results showed no significant difference in gait velocity between the two conditions, thus the presence of the melody condition did not impact the outcome of RAS gait training. On the other hand, all participants showed improvement in gait function after RAS training. The cadence, velocity, stride length, and symmetry were increased and the stride time was reduced after training. The motion analysis demonstrated that the movement patterns of hip and knee joints improved, as they were more similar to normal gait, which indicates that the walkings tance became more stable. The research findings indicate that rhythm is the primary factor in mediating gait functions via RAS training. This study also supports that RAS training can effectively improve the gait function for adolescents with TBI.

The local identity of a female marriage migrant is not fixed to certain boundary or location, but rather comprised flexibly according to geographical movement or new settlement to different place. This research focuses on the local identity and life change of female marriage migrants that are constituted/reconstituted according to spatial transition, or migration. The analysis was conducted to find out traits of changes in the periods of migration and settlement based on the following categorization: multiculturalism and bicultural identity, assimilation and host country identity, exclusion and origin country identity, marginalization and marginal identity. The results are as follows; while having identical experience in terms of a migration, the local identities of marriage migrant women differed according to individual/regional characteristics as well as their respective roles within those traits. In addition, most of females showed passivity in maintaining and exposing their cultural identities of original states. Moreover the life satisfaction change of female marriage migrant that is type of assililation and host country identity is appeared more than others. through this assimilation and accommodation mean adaptation to female marriage migrant lived in Korea. However the intercultural competences of both marriage migrant woman and children in multicultural families facilitate the connection among different cultures. Based on these outcomes, with the transition to multicultural society and space, this research proposes the necessity of fostering global citizenship for mutual recognition of each culture, thus enabling coexistence.

It is very important to establish precisely the historical phases of nursing. We nurses should try to acquire the central social position in the health management system in the near the future, the 21st Century. Therefore my treatise aims to orient the desirable phases of the history of nursing through the feministic survey of the history of nursing from the post medieval epoche to the modern epoche. During the time of the renaissance which gave morning light to the modern epoche, the antique Athenian thinking of sex was again revived. Athenian excluded the women from the public and autonomous regions. All the medical activity, once dominated by the women, was misfortunately regarded as superstition acted by witches. Accordingly, the nursing women were to hunted as witches. In short, in the early modern epoche, women began to be excluded from the history of medical activities. In the middle modern epoche characterized by the enlightenment movement and early capital economic system, capitalistic patriarchal system began to be formed by change in the economic system. The status of women began to be greatly dropped below by the social distinction of the private dimension of home and the Public dimension of job. The woman was deprived of even the occasion to get the official license of medicine and medical institutions were handed to the state or the powerful and rich merchants. Accordingly, nursing acted mainly in the nunnery as the total approach to the patients was destructed wholly and transformed into the means of earning the money. Therefore unprepared low class -women began to engage in nursing only for the money. From then on, nursing activity was tunneled through the dark age for 200 years. In the late modern epoche characterized by the contrast of the accumulated vast capital by industrialization and vast poverty of the peoples, feminism began to float over the surface for the acquisition of equality of men and women from England. A feminist, Nightingale insisted that the women as nurses should be responsible for the healthy life of man. She tried the professional nursing education for women. Accordingly she not only contributed to the intellectual progress of women but also inspired in women the consciousness of the professional job. She tried to realize the ideal of at-that-time-feminists by engaging in nursing all through life. She really paved the road to contemporary nursing. In the near the future, I will write to describe how the late modern epoche nursing has fallen into the dilemma through the 1st and 2nd world wars and matured capitalism and to consider contemporary nursing with the status of women. All these papers aim to give proper recognition of nursing and right orientation of the future 21st Century nursing.

A survey showed that the public perception of the shipping industry's overall image and economic role was relatively positive. The survey revealed that public perception was mixed with respect to the multifaceted role of the shipping industry. Based on the results of this survey, this paper proposes three approaches to improving the public perception of the shipping industry. The organization contact approach includes establishing shipping institutes for city people, holding various events targeted at the public, establishing a shipping memorial hall, developing a shipping-related culture and tourism, reinventing the image of the shipping industry through a shipping-culture movement, and creating new views of the shipping industry by conducting formal education. The goods and services contact approach includes building a brand image for shipping services, providing B2C services, utilizing the national image for the shipping industry, and participating in international cooperation projects. The text contact approach includes B2B advertising, advertisements focused on the national economic and multifaceted role of the shipping industry, package advertisements for the shipping industry and related industries, the Internet and high-technology media, government-initiated PR activities regarding the multifaceted role of the shipping industry, and funding for advertising the shipping industry.
