Normalized Difference Vegetation Index (NDVI) has been used to measure and monitor plant growth, vegetation cover, and biomass from multispectral satellite data. It is also a valuable index in forest applications, providing forest resource information. In this research, an approach for monitoring forest change using MODIS NDVI time series data is explored. NDVI difference-based approaches for a specific point in time have possible accuracy problems and are lacking in monitoring long-term forest cover change. It means that a multi-time NDVI pattern change needs to be considered. In this study, an efficient methodology to consider long-term NDVI pattern is suggested using a harmonic model. The suggested method reconstructs MODIS NDVI time series data through application of the harmonic model, which corrects missing and erroneous data. Then NDVI pattern is analyzed based on estimated values of the harmonic model. The suggested method was applied to 49 NDVI time series data from Aug. 21, 2009 to Sep. 6, 2011 and its usefulness was shown through an experiment.

Migrant Worker arc rapidly increasing in Korea since 1990. They arc nowadays main sources of laborer groups engaging in medium-sized factories. The purpose of this study is to provide the basic information to establish proper oral health policy. Dental caries and periodontal disese are the most common disease that occur in the mouth. Periodontal disease is the most common disease in humans and the biggest reason for the loss of the teeth in the adult population. The CPITIN has been developed jontly by the international Dental Federation and the World Health Organization. CPITN is now an established index of level, of periodontal condition in populations for which specific intervention might be considered. This study was conducted to obtain the information regarding to CPITN of migrant workers Located in Daegu, Questionaire survey was carried out for 289 workers from July 9 to August 8, 2006. Total survey was 289,224 males and 65 females. The result was as follows: First, The number of nationality was 14. The first majority was China as 31.8% Among 14 nationalities were Cambodia 18.0%, Vietnam 12.8%, Sri Lanka 12.1%, Indonesia 7.3%, Nepal 4.2%, the other 13.8%. those who are aged from 20 to 29 were 43.9%, and salary from 1,000,000 won to 1,490,000 won 51.2%.(as for their residence, those who resided) over 3 years were 42.6% and not insured reached 68.5%. Second, more than 93.4% of the subjects need periodontal treatment. only 4.9% of non-smoker was health periodontal states, four times frequency of tooth brushing per a day was 16.7%. Third. 28.7% of migrant workers had experienced visit of dental clinic, and 22.9% had received treatment of decayed tooth. Fourth, It is difficult for them 65.1% of them to visit dental clinic in korea. the First was a communication problem and the second was time. Fifth. Most of them didn`t have a oral health education but 85.1% of them said that they wish they attend oral health education. We conclude that the situation of migrant workers was very bad considering their working conditions, circumstances, and health condition. According to this study, more than 93.4% of the people need periodontal treatment. Besides they didn`t have accurate knowledge about prevention of periodontal disease. Therefor our considering these fads, the policy of dental health by government should be established for migrant workers.

식빵에 단백질을 보강할 목적으로 눈꽃 동충하초와 번데기 동충하초의 분말을 첨가하여 제조한 식빵의 관능적 특성을 측정한 결과는 대조군과 눈꽃 동충하초 첨가군에서 구수한 맛, 입안에서의 감촉, 향의 기호도가 높게 평가되었다. 수분함량은 대조군에 비해 J2군이 가장 높았으며 M4군이 가장 낮았다. 부피는 대조군에 비해 눈꽃 동충하초 첨가군은 커졌고 번데기 동충하초 첨가군은 감소하였으며, 동충하초 첨가량이 증가될수록 감소하였다. 색도에서 명도 값(L)은 대조군을 기준으로 동충하초 첨가군이 모두 낮았으며 특히 M4군이 유의적으로 낮았다. 적색도 값(a)은 대조군을 기준으로 번데기 동충하초의 첨가량이 많을수록 양의 값을 가졌으며 눈꽃 동충하초의 첨가량이 많을수록 음의 값을 나타내 상반된 결과를 가져왔다. 황색도 값(b)은 대조군과 눈꽃 동충하초 첨가군에 비해 M4군이 유의적으로 높았다. 경도(Hardness)는 M4군이 가장 높았으며(p<0.001), 탄력성은 대조군에 비해 눈꽃과 번데기 동충하초 첨가 식빵의 유의적인 차이가 없었다. 관능과 기계적 검사의 상관관계에서, 명도는 관능항목의 색, 경도와 부의 상관관계(p<0.001), 적색도와 황색도, 경도는 관능항목의 색, 묵은 곡식가루 냄새, 경도를 제외한 모든 항목에서 부의 상관관계(p<0.001)를 보였다. 또한 기계적 검사의 응집성과 탄력성은 관능 항목의 색과 묵은 곡식가루 냄새, 경도와 부의 상관관계를 나타냈다. 이상의 결과 눈꽃 동충하초의 경우 2% 첨가군이 대조군과 유사한 경향을 나타냈으며 특히 기호도, 수분 함량과 부피에서 좋은 특성을 가졌다. 동충하초의 첨가량은 눈꽃 동충하초의 경우 4%까지도 무방하며, 번데기 동충하초의 경우 2%가 적절하였다. Paecilomyces japonica and Cordyceps militaris were added to the materials for DongChungHaCho bread, and sensory and mechanical test were performed. Both control and 2% DongChungHaCho added group were acceptable in taste, mouthfeel and odor. Paecilomyces japonica added groups showed higher moisture and volume than control, and Cordyceps militaris groups showed lower moisture and volume. DongChungHaCho added groups showed lower lightness than control. 2% Paecilomyces japonica added group showed similar tendency to control, and it showed the best estimate especially in acceptance, moisture and volume. The optimal addition ratios of DongChungHaCho were evaluated by concentrations of 2% to 4% Paecilomyces japonica and of 2% Cordyceps militaris.
