The analysis of remote sensing data depends on sensor specifications that provide accurate and consistent measurements. However, it is not easy to establish confidence and consistency in data that are analyzed by different sensors using various radiometric scales. For this reason, the cross-calibration method is used to calibrate remote sensing data with reference image data. In this study, we used an airborne hyperspectral image in order to calibrate a multispectral image. We presented an automatic cross-calibration method to calibrate a multispectral image using hyperspectral data and spectral mixture analysis. The spectral characteristics of the multispectral image were adjusted by linear regression analysis. Optimal endmember sets between two images were estimated by spectral mixture analysis for the linear regression analysis, and bands of hyperspectral image were aggregated based on the spectral response function of the two images. The results were evaluated by comparing the Root Mean Square Error (RMSE), the Spectral Angle Mapper (SAM), and average percentage differences. The results of this study showed that the proposed method corrected the spectral information in the multispectral data by using hyperspectral data, and its performance was similar to the manual cross-calibration. The proposed method demonstrated the possibility of automatic cross-calibration based on spectral mixture analysis.

The term "social marketing" was first introduced in 1971 to describe the use of marketing principles and techniques to advance a social cause, idea, or behavior. Social Marketing is a strategy for changing behavior. It utilizes concepts of market segmentation, consumer research, product concept development and testing, directed communication, facilitation, incentives, and exchange theory to maximize the target adopters' response. Social marketing requires knowledge of each target-adopter group, including its 1. social demographic characteristics, 2. psychological profile and 3. behavioral characteristics. To know the target adopters in these three related ways enables social marketer to make more accurate predictions. In addition to differentiating among and selecting target adopter groups, the social marketer will identify influence-holding groups, or influentials, who can affect a program's success. Great changes and opportunities exist to produce changes in the ways that individuals and groups think and behave and in meeting human needs. The balance of the scales of social change, we hope, will shift away from the use of force and violence to the use of persuasion and voluntary action. I trust that this dissertation will be useful highlighting the strategies and means of peaceful, planned social change designed to elevate the quality of life.

Safe underground construction in a rock mass requires adequate ground investigation and effective determination of rock conditions. The estimation of rock mass behavior is difficult, because rock masses are innately anisotropic and heterogeneous at different scales and are affected by various environmental factors. Quantitative rock mass classification systems, such as the Q-system and rock mass rating, are widely used for characterization and engineering design. The measurement of rock classification parameters is subjective and can vary among observers, resulting in questionable accuracy. Geophysical investigation methods, such as seismic surveys, have also been used for ground characterization. Torsional shear wave propagation characteristics in cylindrical rods are equal to that in an infinite media. A probabilistic quantitative relationship between the Q-value and shear wave velocity is thus investigated considering long-wavelength wave propagation in equivalent continuum jointed rock masses. Individual Q-system parameters are correlated with stress-dependent shear wave velocities in jointed rocks using experimental and numerical methods. The relationship between the Q-value and the shear wave velocity is normalized using a defined reference condition. This relationship is further improved using probabilistic analysis to remove unrealistic data and to suggest a range of Q-values for a given wave velocity. The proposed probabilistic Q-value estimation is then compared with field measurements and cross-hole seismic test data to verify its applicability.

This study suggests that Korea - Russia economic cooperation, which has been sluggish in the meantime, should be revitalized as a small, medium sized business that can be practiced at the local level of both countries. Some large scales of national projects were difficult to realize due to some internal and external factors. Therefore, if Russia's Far East region of the complementary economic structure with the Korea's Gyeonggi Province of Korea could form the basis of cooperation by centering on SMEs, it further can be positive for promoting cooperation among South Korea, North Korea and Russia. The trilateral cooperation among two Koreas and Russia is necessary for the balance of political and economic powers in the East Asia. China's retaliation case regarding THAAD (Terminal High Altitude Area Defense) clearly showed that the greater the economic dependence on a particular country, the more threatening it could be. Therefore, it is important for the political and economic security to keep the balance by diversifying economic cooperation counterparts. As China's influence in the global economy grows, building value chains for mutual prosperity with various neighboring countries is gaining great importance. To this end, this paper examined Russia's Eurasian Strategy, New East Policy, and Far East Development Policy which were designed to seek the way to establish Russia's independent economic zone not absorbed by Europe and China.

Currently, there is insufficient research on the construction management performance since the CM system was introduced in Korea. For successful completion of construction projects, active use of construction mangers on projects is necessary by introducing construction management to the projects. In view of this, this study analyzed the annual CM performance from 1996 to 2013 but for the past 5 years from 2009 to 2013, a detailed analysis was carried out. For different sectors, CM performances were divided into public and private sectors, for project types, construction, civil and others, for project phases, pre-design, design, construction and post-construction phases, for contract types, sole and joint contract types, for project scale, the amount of the projects was taken into consideration and they were divided into large, medium and small scales and for the types of projects, they were divided into, shops, department stores, shopping centers, hospitals, government buildings, hotels, accommodation facilities, factories, buildings for workshops, office buildings, stadiums, playgrounds, schools and other construction types and all the data divided into such categories was analyzed. The results in this study can be used as a basic reference for studies in analysing construction management performances.

초지피복 조건에서 사면의 일사수광량 차이가 일 최고기온에 미치는 영향을 파악하기 위해 2007년 하지부터 동지까지 밑면지름 570m, 높이 90m인 원추형 기생화산 "높은오름"의 측면 경사 8 지점에서 일 최고기온을 측정하였다. 8개 지점 평균값을 기준온도로하여 각 지점의 기온편차를 구해 비교한 결과 기온편차는 하지로부터 동지로 갈수록 커지는 경향이었고, 관측기간 평균은 남향사면에서 $1.0^{\circ}C$, 북향사면에서 $-0.8^{\circ}C$로서 그 차이가 평균 $1.8^{\circ}C$에 달했다. 기온편차의 월별 평균은 11월에 가장 크며 남향사면에서 $2.1^{\circ}C$, 북향사면에서 $-1.3^{\circ}C$였다. 일별 기온편차의 최대값은 남향사면에서 $3.8^{\circ}C$, 북향사면에서 $-2.7^{\circ}C$에 달했는데, 이러한 기온편차 변이는 일사수광량 편차에 근거한 지형특성지수와 높은 상관을 보여 복잡지형의 일 최고기온 추정모형 개발에 활용될 수 있을 것으로 기대된다.

본 연구는 도박중독문제를 어떻게 정의하고 접근해야 최선일 것인가에 대한 근본적인 질문에서 시작되었다. 이에 도박중독문제의 본질을 규정하고, 도박중독 발생과 유지에 영향을 미치는 다양한 요인들을 포괄하여 도박문제를 이해하고자 하였다. 이러한 작업이 선행된 후에야 도박의 문제를 정확하게 진단, 분류, 평가하고 나아가 유병률이나 발병률의 균형잡힌 산정도 가능할 것이기 때문이다. 우선 도박중독 개념과 관련하여서는 전문가 간에 상이한 견해를 보이고 있으므로 도박 중독에 대한 광의의 정의와 협의의 정의 등으로 세분하는 것이 의사소통에 혼란을 방지할 수 있을 것으로 생각된다. 또한 도박행동을 중독인가 아닌가, 병적인가 아닌가 등 이분법적으로 구분하기보다 연속선상에 존재하는 것으로서 바라보아야 할 것이다. 이와 함께 최근 등장하고 있는 도박행동에 대한 다원적 및 다층적 관점을 소개하였는데, 이러한 관점의 장점은 도박문제를 개인의 책임으로만 떠넘기는 것이 아니라 도박문제와 관련된 다양한 주체들이 책임을 나누고 문제해결을 위해 공동대처하도록 촉진한다는 점이다. 또한 현재 국내에서 사용되고 있는 도박중독 평가척도들의 제한점을 극복한 척도의 제작이 필요한 바, 새로운 척도 개발 시 필요한 유의사항을 밝혔다. 마지막으로 도박관련 정책 추진시 유병률과 발병률의 산정이 중요한 이슈로 부각되는바, 도박중독문제의 본질에 충실한 유병률과 발병률 추정을 위한 방안을 제시하였다.

Objectives: Literature Study of clinical cases with Traditional Chinese Medicine (TCM) as reference for Korean medicine based treatment of juvenile patients with Down's syndrome. Methods: 4 TCM journals with the highest impact factors were searched and selected among the journals listed in www.cnki.net. The search keywords were "蒙古症", "唐氏症(産生唐氏症)", "唐氏症候群", "先天愚型", "伸舌樣痴呆", "21三体綜合徵", "三染色体症", "Down's syndrome", and "Mongolism". Accordingly, searched papers were analyzed. Results: Total 6 studies were selected: RCT(5), case report(1). Among the RCT related studies, 2 studies tested the effect of Electroacupuncture (電鍼), 1 study tested the effect of Electroacupuncture and Pharmacopuncture (藥鍼) treatment together, and 2 studies tested the effect of Electroacupuncture and Herbal Medicines (藥物) co-treatment. In all the studies, the study groups showed significantly improved intelligence quotient (IQ) in comparison with the control groups. The case report showed improvement of cognitive ability and other clinical parameters as a result of Acupuncture (鍼) and Herbal Medicines co-treatment in juvenile patients with Down's syndrome. Conclusions: Clinical studies testing the effect of TCM for the treatment of Down's syndrome have been conducted in small scales, and all the studies showed a certain level of brain function improvement of the patients in the study groups. These results implicate that the methods in Korean medicine can be highly potential treatment options for the treatment of Down's syndrome. Conduction of accurate and well-controlled studies in large scale would be required to prove the effect of Korean medicine for the treatment of patients with Down's syndrome.

Nutritional status and dietary intake play a significant role in the prognosis of breast cancer and may modify the progression of disease. The aim of this study was to determine the influence of nutritional status on the quality of life of Iranian breast cancer survivors. Cross-sectional data were collected for 100 Iranian breast cancer survivors, aged 32 to 61 years, attending the oncology outpatient clinic at Golestan Hospital, Ahvaz, Iran. Nutritional status of subjects was assessed by anthropometric measurements, Patient-Generated Subjective Global Assessment (PG-SGA) and three non-consecutive 24-hour diet recalls. The European Organization of Research and Treatment of Cancer Quality of Life form (EORTC QLQ-C30) was used to assess quality of life. Ninety-four percent of the survivors were well-nourished, 6% were moderately malnourished or suspected of being malnourished while none were severely malnourished. Prevalence of overweight and obesity was 86%. Overall, participants had an inadequate intake of vitamin D, E, iron and magnesium according to dietary reference intake (DRI) recommendations. Survivors with better nutritional status had better functioning scales and experienced fewer clinical symptoms. It appears important to provide educational and nutritional screening programs to improve cancer survivor quality of life.
