Comparison study on the land surface temperatures, which are calculated from four different algorithms for MODIS data, was carried out and the characteristics of each algorithm on land surface temperature estimation were also analysed in this study. Algorithms, which are well used for various satellite data analysis, in the comparisons are proposed by Price, Becker and Li, Ulivieri et al., and Wan. Verification of estimated land surface temperature from each algorithm is also performed using observation based regression data. The coefficient of determination ($R^2$) for daytime land surface temperature estimated from Wan's algorithm is higher than that of another algorithms at all seasons and the value of $R^2$ reach on 0.92 at spring. Although $R^2$ for Ulivieri's algorithm is slightly lower than that for Wan's algorithm, the variation pattern of land surface temperature for two algorithms are similar. However, the difference of estimated values among four algorithms become small at the region of high land surface temperature.

In the radically changing market situation, surface materials of student furniture are a very important element to decide the consumption pattern and the market price. Thus, this study examined the characteristics of surface materials by classifying the student furniture into children's, juniors', and seniors' furniture while accessing the features of such surface materials through Glulam, veneer, poly paper, finishing foil, high pressure melamine (HPM), and low pressure melamine (LPM), and PVC vinyl. When taking a look at the surface materials that were most frequently produced in each domestic furniture company, the combined materials that used more than 2 elements (31.88%), LPM (23.19%), and Glulam (20.29%) were introduced at the market in the order. Regarding the analysis made on colors, the combination colors took more than half (55.32%) followed by brown (13.83%) and beige (11.7%) in the order. Based on the results derived from the analysis, the study suggests to stress more importance to surface materials when developing student furniture and to exert efforts for the consistent development of new materials and quality improvement, as a way to accelerate the development of the furniture industry in Korea.

The purpose of this study compares determinants of eldery medical cost inflation with those of other age groups by analysing aggregated data with a deterministic model. The deterministic model of per capita medical cost inflation consists of increases in price, intensity of services, and medical utilization. We used a time series data($1985{\sim}1991$) from National Medical Insurance and analyzed by age groups. In total population, the average increase rates of inpatient and outpatient medical costs were respectively 9.5% and 8.8% during 6 years and the major cause of inflation was the increase in service intensity in both of inpatient and outpatient cases. But in the population of 65 years old and over, the average increase rates of inpatient and outpatient medical costs were respectively 13.8% and 14.8% and the major cause of inflation was the increase in per-capita medical utilization in both of inpatient and outpatient cases. Also, the increase in service intensity of 65 years old and over was the highest of other age groups. This pattern was similar during study periods. We concluded that the level of medical cost-inflation and the determinants in eldery was the highest-especially in per capita medical utilization, therfore, the inflation of medical costs in eldery will be higher than other age groups for the furture in Korea.

Recently, it is one of the popular fashion and cultural events that people of the younger generation put on a hanbok and take a picture together with communicating by SNS. For this reason, the rent-hanbok market takes a big part of the Korean traditional costume market. Therefor, the recognition of hanbok is changed from the style of uncomfortable and ceremonial clothes, to becoming popular as everyday dress in the younger generation. The various designs of the rental hanbok show two different opinions. One is the increasing popular and general public interest and demand for wearing and showing off traditional hanbok fashions in a positive outlook. Another is the case of the wrong stereotype and knowledge for traditional costume which results in a negative outlook for this type of fashion statement. This study is to look into renting hanbok jeogori for women in Seoul and in Junju. There are 39 styles available in joegori. That being noted, the traditional jeogori has seop and git with dongjung. But it is seen that rental jeogoris do not have the seop, or have the dongjung position as similar to the Po as seen on the men's coat. The showy and colorful materials feel bad and are poorly ventilated. And excessive price competition causes a decreased quality of renting hanbok. Now the rental hanbok business needs to change; to have to make renting hanbok with the correct historical understanding, and it is necessary to have to stop the indiscriminate acceptance of foreign culture.
