The main goal of construction projects from the past has been enhancing efficiency by reducing cost and time. but, seeing the current condition of safety management of many construction companies nowadays, it is true that not much attention has been paid to safety management for a long time. However, there are paradigm shift from the cost and term of works to safety management in the construction industry, from this circumstance the safety management is evaluated more importantly. Though less accident happens compared to past, the accidents are getting greater because construction projects nowadays are bigger and more complex and monetary loss from the accidents are increasing. Also, the severity is getting greater and even fatal. For this reason, more improved safety management is very necessary. Therefore, we are to propose more efficient system for safety management in this thesis. Technical parts for developing system include many technique such as Real Time Locating system, and other techniques like Monitoring module based on BIM, Data Mart, Alarm are also applied together. Through this system, in the construction site, safety management is performed more effectively and widely because the system can manage the human resource and fluid situation. Also, safety manager can conduct more systematically and advanced safety management through human resource dominated safety management.

Customized medical care and services timely providing effective prevention and treatment by collecting and using individuals' biomedical data are recently possible and utilized for users' health care. They are developed as the real-time health care services and information is provided to individuals by using smart phones, PC, tablet, etc. Interactive communication is supported by informing managers of analysis data and results, through collected data. It is therefore the time for constructing health care. This study attempts to prepare for patent applications of technical development at this time, by analyzing the tendency of smart wearable health care technologies, including biological signal-based health care devices and real-time health care system. Patents regarding smart wearable health care technologies were reported to have the relatively higher concentration of research development. Korea focuses on patent activities for real-time health care systems across the intervals of analysis, while U.S and European countries actively make efforts for patent activities regarding health care devices Japan conduct patent activities across health care devices and systems, based on bio-technologies. Korea has recently dominated the market of patents for bio-technologies-based health care devices and real-time health care devices and also appears to secure patents for the technologies and the market, so entry barriers to the market of smart wearable health care technologies are determined to be higher in Korea. It is important to establish the portfolios of patents, by securing patent rights for the figures of products, manufacturing methods and other related technical systems, if technologies are planned to be commercialized.

In this study we analysed time allotment and the contents of a health textbook and its teacher's guide book of the 7th elementary curriculum. We intended to offer the basic data needed to establish the single health education. So the analysed results are as follows according to the health education model developed by the korean nursing association and health teachers' meeting and the teaching time allotment presented by the teacher's guide book. It's goal is practice in regular class time of the subjects for the time and contents of health education in the 7th elementary curriculum. The total class periods of health education of the 7th elementary curriculum are 229 hours and annual periods of health education per year are an average of 38 hours. The health education of the 7th elementary curriculum is separated into the 9 following subjects: Wise life, Pleasant life, Righteous life, We are 1st grade, Physical education, Science, Social studies, moral education and Practical course. The health education of the 6th elementary curriculum was combined with the units of physical education, but in the 7th curriculum it must be separated by a single, required health subject. The contents of health education of the 7th elementary curriculum is mostly dominated by units of community and environmental health with a total of 55 hours (24%). Therefore, the units of home health and social health, development of physical strength are fairly insignificant. The newly added contents in the 7th curriculum are "pregnancy and child birth, the protection and counterplan from rape, the reasons and prevention of stress, the reasons and the treatment of obesity, the damage of smoking and drinking, etc. According to the result above, we must establish the criteria for each year's health education in the 8th elementary curriculum. The contents of mental health, home health and social health should be revised and added new items. The health education that is separated in some subjects now must be established as a systematically integrated health education.

Influences of orographic and ocean effect, which depend on the detailed geographic characteristics, upon winter time (December-February) precipitation in the Yeongdong region are investigated. Most of precipitation events in the Yeongdong region during the wintertime are associated with moist northeasterly (coming from the northeast direction) winds and also the spatial distribution of precipitation shows a great difference between Mountain area (Daegwallyeong) and Coastal area (Gangneung). The linear correlation coefficient between the meteorological variables obtained from NCEP/NCAR Reanalysis Data and precipitation amount for each precipitation type is calculated. Mountain type precipitation is dominated by northeasterly wind speed of the low level (1000 hPa and 925 hPa) and characterized with more precipitation in mountain area than coastal area. However, Coastal type precipitation is affected by temperature difference between ocean and atmosphere, and characterized with more precipitation in coastal area than mountain area. The results are summarized as follows; In the case of mountain type precipitation, the correlation coefficient between wind speed at 1000 hPa (925 hPa) and precipitation amount at Daegwallyeong is 0.60 (0.61). The correlation is statistical significant at 1% level. In the case of coastal type precipitation, the correlation coefficient of temperature difference between ocean and 925 hPa (850 hPa) over the East sea area and precipitation amount at Gangneung is 0.33 (0.34). As for the mountain type precipitation, a detailed analysis was conducted in order to verify the relationship between precipitation amount at Daegwallyeong and low level wind speed data from wind profiler in Gangneung and Buoy in the East Sea. The results also show the similar behavior. This result indicates that mountain type precipitation in the Yeongdong region is closely related with easterly wind speed. Thus, the statistical analysis of the few selected meteorological variables can be a good indicator to estimate the precipitation totals in the Yeongdong region in winter time.

This study probed into the fashion of modern girls between the 1920's and the 1930's who led the mentality and fashion of women as the progenitor of the alpha girl in Korea. For this, the fashion of actual people who received attention as modern girls in various occupations and that of modern girl heroines reinterpreted in films were examined. Methods included the theoretical study based on fashion related newspaper articles at the time, specialized publications, advance researches, and internet data and the empirical study that involved contents analysis centering on visual data. The Western women's fashion between the 1920's-1930's was dominated by the garçonne look to promote women's entry into society and competition against men and the practical and mature long and slim look due to the influence of economic recess. Korean people also adapted Western clothes following Western fashion while also modified the traditional clothes and wore modified Korean clothes. The fashion of 5 actual modern girls of Korea and that of 3 film heroines were examined. The fashion of actual people most well represented the fashion trends at the time and that they used fashion as the means to express their mentality and their artistic propensity and professionalism were expressed through fashion. On the other hand, the fashion of film heroines substantially expressed various occupations of the characters in the film and reflected trendy clothes and cosmetics, and it showed sexy and romantic fashion trend due to the influence of modern trends and reinterpretations.

Discharge or water level predictions at tidally affected river reaches are currently still a great challenge in hydrological practices. This research aims to predict water level of the tide dominated site, Jamsu bridge in the Han River downstream. Physics-based hydrodynamic approaches are sometimes not applicable for water level prediction in such a tidal river due to uncertainty sources like rainfall forecasting data. In this study, TensorFlow deep learning framework was used to build a deep neural network based LSTM model and its applications. The LSTM model was trained based on 3 data sets having 10-min temporal resolution: Paldang dam release, Jamsu bridge water level, predicted tidal level for 6 years (2011~2016) and then predict the water level time series given the six lead times: 1, 3, 6, 9, 12, 24 hours. The optimal hyper-parameters of LSTM model were set up as follows: 6 hidden layers number, 0.01 learning rate, 3000 iterations. In addition, we changed the key parameter of LSTM model, sequence length, ranging from 1 to 6 hours to test its affect to prediction results. The LSTM model with the 1 hr sequence length led to the best performing prediction results for the all cases. In particular, it resulted in very accurate prediction: RMSE (0.065 cm) and NSE (0.99) for the 1 hr lead time prediction case. However, as the lead time became longer, the RMSE increased from 0.08 m (1 hr lead time) to 0.28 m (24 hrs lead time) and the NSE decreased from 0.99 (1 hr lead time) to 0.74 (24 hrs lead time), respectively.

The present research analyzed the social meaning of Korean clothing in women's magazine. The data were included the advertisements and publicity related to Korean clothing in two women's magazines and condensed at 5 year intervals with content analysis. The identified 276 advertisements and publicity were categorized into four areas. The categories were the trend of exterior growth of advertisements and publicity, appeals and approach, the elements of advertisements and publicity including background, the relation of models, situations, and styles of Korean clothing over times. The results of the study were as Follows: 1. In conjunction with external growth of advertisements and publicity of Korean clothing, the social meaning of Korean clothing has changed from ceremonial clothing to daily-wear clothing. Especially since 1980, the theme of advertisement and publicity of Korean clothing were changed form the beauty of traditional Korean clothing such as grace of dignity to the individuality which was the typical value of western Clothing. 2. The trends of appeals related to Korean clothing and applied Korean clothing have reflected the changing time and society. Since 1980, the emotional or mixed approach with metaphor have increased, whereas factual or situational approach were dominated in 1960s and 1970s. 3. The styles including silhouette, detail, textile and pattern of Korean clothing and applied Korean clothing also reflected the changing trends of Korean society. Especially since 1980, the applied style of Korean clothing has adopted the trends of western clothing. Implications for the future research were suggested.

In this paper, the light emitting efficiency, spectrum, and the lifetime of the phosphorescent devices, whose emission characteristics are strongly dominated not only by the energy transfer but also by the charge carrier trapping induced by the emissive dopant, are explained by differences in the energy levels of the host, dopant, and nearby transport layers. On the basis of our finding on device performance and photocurrent measurement data by time-of-flight (TOF), we investigated the effect of the difference of carrier trapping dopant and properties of the host materials on the efficiency roll-off of phosphorescent organic light emitting diode (OLED), along with a physical interpretation and practical design scheme, such as a multiple host system, for improving the efficiency and lifetime of devices.

The primary objective of this research is to explain how to implement the Service Oriented Architecture (hereafter SOA) enabled Enterprise Resource Planning (hereafter ERP) system successfully for service industries. An implementation of the ERP system help many organizations to alleviate the difficult job of supporting inflexible or legacy systems that in most cases result in cost increases, data redundancy and inaccuracy, and various inefficiencies. However, the ERP system is losing its market share rapidly to the cloud computing system which utilizes the Software-as-a-service (hereafter SaaS) and SOA. The SOA is an approach to integrate various types of IT resources to leverage existing ERP system, while at the same time building an infrastructure that can readily respond to new business environment and offer new dynamic applications. The companies that implement this system have less of a need for the kinds of all-in-one ERP system that have dominated the back office for decades and can move freely to best-of-breed applications. This research will identify the benefits and costs of the SOA enabled ERP system through case studies and its impact on competitive priorities such as cost, quality, delivery, and flexibility.

Cochlodinium polykrikoides red tides have caused great economic losses in the aquaculture industry in many countries. To investigate the roles of metazooplankton in red tide dynamics of C. polykrikoides in the South Sea of Korea, the abundance of metazooplankton was measured at 60 stations over 1- or 2-week intervals from May to November 2014. In addition, the grazing impacts of dominant metazooplankton on red tide species and their potential heterotrophic protistan grazers were estimated by combining field data on the abundance of red tide species, heterotrophic protist grazers, and dominant metazooplankton with data obtained from the literature concerning ingestion rates of the grazers on red tide species and heterotrophic protists. The mean abundance of total metazooplankton at each sampling time during the study was 297-1,119 individuals $m^{-3}$. The abundance of total metazooplankton was significantly positively correlated with that of phototrophic dinoflagellates (p < 0.01), but it was not significantly correlated with water temperature, salinity, and the abundance of diatoms, euglenophytes, cryptophytes, heterotrophic dinoflagellates, tintinnid ciliates, and naked ciliates (p > 0.1). Thus, dinoflagellate red tides may support high abundance of total metazooplankton. Copepods dominated metazooplankton assemblages at all sampling times except from Jul 11 to Aug 6 when cladocerans and hydrozoans dominated. The calculated maximum grazing coefficients attributable to calanoid copepods on C. polykrikoides and Prorocentrum spp. were 0.018 and $0.029d^{-1}$, respectively. Therefore, calanoid copepods may not control populations of C. polykrikoides or Prorocentrum spp. Furthermore, the maximum grazing coefficients attributable to calanoid copepods on the heterotrophic dinoflagellates Polykrikos spp. and Gyrodinium spp., which were grazers on C. polykrikoides and Prorocentrum spp., respectively, were 0.008 and $0.047d^{-1}$, respectively. Therefore, calanoid copepods may not reduce grazing impact by these heterotrophic dinoflagellate grazers on populations of the red tide dinoflagellates.
