This study conducted a comparison analysis on the difference in the subjectivity structure of Korean and Chinese consumers based on their types of perception on advertisements of automobiles which has a high degree of self interest. The primary reason for conducting a comparison study of Korean and Chinese consumers was to concretize the characteristics of Chinese consumers who have enormous potential and rapid growth in the global market. In addition, by comparing the characteristics of Korean and Chinese consumers that changed with differences in social systems and socio-economic characteristics, the purpose was to present an advertising strategy idea that is useful for both countries. Furthermore, when taking into consideration the reality that the world must compete in a single market commonly referred to as the global market, understanding the subjectivity structure of perception of Korean and Chinese consumers is critical in establishing a strategy for occupying the upper position of dominance in such competition. Based on the results of the study, subjectivity structures on the perception of advertisements possessed by Korean and Chinese consumers of the same Asian culture differed but were mutually interrelated. Such results suggest that there is a need for further studies of generalization and objectification through a quantitative approach.

Catchments soil erosion, one of the most serious problems in the mountainous environment of the world, consists of a complex phenomenon involving the detachment of individual soil particles from the soil mass and their transport, storage and overland flow of rainfall, and infiltration. Sediment size distribution during erosion processes appear to depend on many factors such as rainfall characteristics, vegetation cover, hydraulic flow, soil properties and slope. This study involved laboratory flume experiments carried out under simulated rainfall in a 3.0 m long ${\times}$ 0.8 m wide ${\times}$ 0.7 m deep flume, set at $17^{\circ}$ slope. Five experimental cases, consisting of twelve experiments using three different sediments with two different rainfall conditions, are reported. The experiments consisted of detailed observations of particle size distribution of the out-flow sediment. Sediment water mixture out-flow hydrograph and sediment mass out-flow rate over time, moisture profiles at different points within the soil domain, and seepage outflow were also reported. Moisture profiles, seepage outflow, and movement of overland flow were clearly found to be controlled by water retention function and hydraulic function of the soil. The difference of grain size distribution of original soil bed and the out-flow sediment was found to be insignificant in the cases of uniform sediment used experiments. However, in the cases of non-uniform sediment used experiments the outflow sediment was found to be coarser than the original soil domain. The results indicated that the sediment transport mechanism is the combination of particle segregation, suspension/saltation and rolling along the travel distance.

Background: Androgen receptors (ARs) are expressed in more than 70% of breast cancers (BCs) and have been implicated in BC pathogenesis. Some triple negative (TN)BC tumors express AR and may benefit from AR-targeted therapies. The aim of this study was to evaluate survival and the prevalence of AR expression and its correlation with other risk factors in triple negative BCs in women from Western Iran. Materials and Methods: In a retrospective study between 2009-2015, 41 patients with TNBC were referred to the Private Clinic of Oncology, Kermanshah city, Iran. ER, PR and AR-positive expression was defined as ${\geq}10%$ nuclear staining and also HER2 (2+), FISH was performed. Nuclear staining was considered representative for Ki67 and P53. The mean follow-up for the patients was 25 months. In this time, 5 patients died and 4 lost to follow-up were censored from survival analysis. Results: The mean age at diagnosis was 46.9 years (range, 24-71 years) and all patients were female. The OS rates for AR-positive and AR-negative patients were 90% and 85.1%, respectively, and the mean OS was 26.3 and 23.2 months. Therefore, there was no significant difference between the two groups (Hazard ratio: 0.580, 95% CI: 0.086-3.893, P=0.575). Conclusions: In TNBC patients, evaluation of AR status may provide additional information on prognosis and treatment. The results of studies showed that the prevalence AR expression may differ in the world and probably ethnicity can be an influencing factor.

Background: Propolis based preparations have a wide range of applications in various specialties of dentistry. The aim of this clinical trial was to test the efficacy of propolis as a mouthwash in the reduction of chemotherapy induced oral mucositis (OM) in a single center. Materials and Methods: In this randomised, controlled study patients undergoing chemotherapy were included consecutively and randomised to an experimental group receiving propolis mouthwash (n = 20) and a control group receiving diluted water (n=20). Oral mucositis, erythema and eating and drink ability were assessed at baseline and after 3 and 7 days using the World Health Organization (WHO) scale and the oral mucositis assessment scale (OMAS). Results: There were significant differences in OM, wound and erythema in propolis group compared to placebo, but no significant difference in eating and drink ability. However, it was interesting that 65% of the patients in the propolis group were completely healed at day 7 of the trial. No significant adverse events were reported by the patients. Conclusions: This study found that oral care with propolis as mouthwash for patients undergoing chemotherapy is an effective intervention to improve oral health. Our findings shouldlencourage health practitioners to apply propolis mouth rinse for the oral care of patients under chemotherapy.

Background: In our study, the LDH, albumin, hemoglobin, neutrophile, thrombocyte, lymphocyte counts and prognostic significance of neutrophile-lymphocyte and thrombocyte-lymphocyte ratios in NSCLC derived from these counts obtained during regular examinations of patients were examined. Materials and Methods: Histopathologically diagnosed non-small-cell-lung cancer patients between 2008 and 2010 were included in the study. Before the treatment, full blood count including routine lymphocyte count, blood biochemistry examinations including liver (AST, ALT, total protein, Albumin), LDH and kidney (BUN, Cre) function tests were performed. Results: A total of 156 patients, 76 of whom (48.7%) were female and 80 of whom (51.3%) were male were included. Mean hemoglobin level was determined as 12. Overall survival was found to be significantly dependent on whether patients were anemic or not (p: 0.005). Mean LDH level was determined as 233.4. There was nosurvival difference between patients with and without high LDH (p: 0.532). In patients where NLR showed systemic inflammatory response, overall survival was 10.8 months whereas this duration was 19.6 months in patients where the systemic inflammatory response was negative (p: 0.012). In patients where TLR showed systemic inflammatory response, overall survival was 13.6 months whereas this duration was 21.9 months in patients where the systemic inflammatory response was negative (p: 0.04). Conclusions: Molecular methods have been changing rapidly in today's world and they manage the treatment besides defining the prognosis of patients. However, easily accessible and cheap laboratory parameters should be considered in the prognosis of patients besides these new methods.

The purposes of this research are to investigate the pollution level of heavy metals due to the urbanization and industrialization in the satellite cities of Seoul, and to assess the chemical species and the sources of heavy metals in highly contaminated soils and dusts. Soil and dust samples were collected from the Uijeongbu and the Koyang cities, which are northern and the northwestern satellite cities of Seoul metropolitan city, respectively. Relatively high pH values($6.3{\sim}9.9$) were found in roadside soils compared with agricultural and forest soils. Difference in pH values of soils was not identified between before and after rainy seasons. In spite of no specific pollution sources in the above cities, the contents of Cu, Pb, and Zn in soils and dusts were much higher than the world average contents. The metal levels in dusts were higher than those in soils, but the metal concentration in dusts was significantly decreased after rainy season. Pollution index was high(> 1.0) in the areas of heavy traffic, industrial complex, and city centres. There is an appreciable proportion of total Zn in exchangeable/water-acid soluble fraction. Copper is predominantly associated with reducible and oxidizable phases, whereas Pb is largely in reducible association. It is concluded that the mobility and bioavailability of metals are high in the order of Zn >> Cu > Pb, on the basis of characteristic particle morphology and chemical composition, Pb-containing particles are originated probably from the automobile exhaust, particularly in heavy traffic areas. The metallic forms and iron-oxide associated forms of Cr, Ni, Cu, Zn, and Pb can be assessed as industrial origin.

People's interest in the environmental problems of the Earth is growing as they come to the modern world, and research is being actively conducted on how to protect the environment. As a result, the automobile industry, one of the causes of environmental pollution, is also affected. Therefore, research is being conducted to improve the fuel economy and light weight of cars, development of pollution-free cars such as electric cars, and aluminium materials that are lighter than ordinary steel sheets and easier to recycle are gaining attention. In this experiment, the material was formed to form a form of aluminium and the material reduction rate of the side wall of the foam was tested according to the amount of side wall. The material used in the experiment was A3003-O, which is less plastic than normal steel plates, but has excellent corrosion resistance, plasticity and weldability compared to aluminium materials, but has poor tensile strength. For tensile testing, a certain array of Forming Shapes was molded and the height of the Forming was set to 5mm, and the height of the Forming was 4.7mm, indicating that the difference between the first 5mm Forming and the height was not large. In addition, the material reduction rate was tested by giving 15, 0, and -0.15 teas, respectively, and was found to be valuable as a product only for -0.15.

With the reduction of contagious diseases throughout the world and prolonged life expectancy has lead into increase of habitual related diseases. Industrial development and better economic situation made people more concerned about their health. As primary illnesses are subdued in the past years, health care system and the public value prevention and well-being more than the treatment itself. Based on this trend, this study focused on the view of life from the perspective of Oriental medicine as it's peculiarities, regimen methods, and the definition of healthy life are evaluated. Following results were obtained: - View of life in Oriental medicine focused on two basic principles of interrelationship between the organs internally, inter-dependency with the natural environment and social surrounding externally as recognition and respect between the medium were valued. - Sustaining and maintaining good health in Oriental medicine are closely related to prenatally healthy pregnancy and fetation, as well as prenatal training. Postnatal maintenance includes accommodation to seasonal changes, adequate food intake, mind control, various regimen methods and avoidance of wrong doings. - Defining health includes body's internal condition and external influences, principles of essence, qi, spirit, and yin and yang, harmony and balance, and individuality. - To conclude, good health in Oriental medicine is defined as 'external adaptation to society and natural environment, and internal balancing of individual difference with accumulation of essence, nurturing and circulating qi, and every material around the body in harmony and balance."

As information and communications technology (ICT) becomes increasingly integrated into the daily lives of people around the world, it is important to know how the technology is influencing the behaviors of individuals and families. This study looked at the ecology of families as it is related to ICT and the changes to processes that occur as ICT devices and services are integrated into the family. A survey of 1084 families was conducted. Five hundred of the families were from the United States and 584 families were from Korea. Significant differences were found in the use of ICT by Korean and American families although the source of this difference was not clearly identified in this study. Three clusters of families were identified based on their use of devices and services. These were labeled as; 'The Tech Savvy', 'The Wireless Users', 'The In-betweeners', 'The Wired', and 'The Just Mobile'. 'The Tech Savvy' used the greatest variety of ICT technologies and 'The Wired' used the fewest. Other clusters fell in the middle with families seemingly using the devices which met their particular needs. Two factors related to ICT integration into the family were identified. These were related to family intimacy and family relationship maintenance. The family cluster identified as 'Tech Savvy' made significantly greater use of ICT in these relationships and 'The Wired' made the least use of ICT in these areas. The other clusters tended to be between the two ends and tended not to be significantly different from each other in their use of ICT. Finally, models for ICT use by families showed that demographics, nation of origin, types of devices and services used, and attitude and interest in ICT all had a significant impact.

The purpose of this study is to help out the settlement of the Green Map in Korea, and to suggest how to map, and help community people and environmental planner systematically take care of their own towns. This study is also to introduce the green mapping and its usefulness, based on the Green Map Movement, which originated from Net York City and has been expanding through the World. Environmental elements shown on the Green map vary between countries and for the Seocho-Gu Green Map, we have decided to indicate the places that we are proud of, and dishonored of. Especially, this paper is focused on finding the hidden environmental resources in our daily lives. Seocho-Gu, one of 25 self-governmental resources. Since the citizens and government officials are open-minded in their environments, it is a suitable area to start the first Green Map in Korea. As a method of locating the environmental resources, the "Foot Sensing Method" by which residents directly research, is the main difference from typical maps by the "Remote Sensing" which focused on the variety participation of the residents such as questionnaires, investigation with youth volunteers, users interviews which may be more meaningful than the Green Map itself. The purpose of application plan is to preserve the environmental resources through the smooth feedback with the residents. Thus, it must be acted as a opening window linking them with the local circumstances. In line with this, this study proposed the trial-version Web Green Map and Green tour plan. Recently, a need for an environmental map has been reflected in the environmental policies of Seoul Metropolitan City, and it is in place now. If environmental experts of different disciplines use the Green Map for landscape architecture, design, and city planning, it will help them make a better understanding of the needs of the community and to practice the user-centered design. Eventually, the Seocho-Gu Green Map will help its residents, tourists, government, and environmental planners continue establishing the healthy city environments. It is expected that the green map will be employed as a useful method for establishing healthy city and town through right way of use and contents.of use and contents.
