  • The crystal structure of the title compound was determined from single crystal X-ray dirt fraction study : C16H16NO3, Mr=271.316, orthorh ombic, Aba2, a=15.750(3), b=13.470(2), c=13.356 (2) A, V=2833A, Z=8, Dx=1.26 Mgm-3, λ(MoK a) =0.71069A, r=0.51mm-2, F(000)=1136, T=291 K, R=0.0414 for 728 unique observed [F≥3e(F)] reflections and 240 parameters. The molecule is nearly planar within 0.2 A with the torsion angle -179(2)°for C(4)-C(7)-C(8)-C(9).The into rmolecular interactions are mainly by van der Waals force with the nearest intermolecular distance 3.647A between O(3) and C(4) translated by half unit along band c-axes.

  • This research is a qualitative based study by using data gleaned from documentary analysis and in-depth interviews of 10 potential stakeholders were involved in the proposed high-speed train project in Thailand. Many perspectives from key informants revealed that this project would bring Thailand sustainable development in the future due to the fact that it is supposed to be an environmentally friendly mode of transportation and timesaving for passengers. Key informants who tend to have negative opinions towards the project feel apprehension due to the huge monetary investment during a time of monetary crisis. However, there was one complaint that the high-speed train is harmful to the environment surrounding the proposed area of this project. Several key informants agreed that ticket fares must be in between the cost of a bus ticket and airfare.

  • Such Hinterland in New Busan-Jinhae Port are so placed as to do harm to their surrounding residential areas due to traffic, noise and dirt, etc. according to the current plan. So they are likely to fail to serve as harbors and residential districts. Because this is responsible for a conflict between harbors and urban functions, plans for the use of such areas should be well planned enough to achieve win-win results by getting rid of a conflict between the harbors and urban functions by creating manufactural and industrial complexes and green parks close to harbor logistics, by consolidating the functions of the cities through exchanges, commercial business and educational facilities and by adding comfort facilities at the hinterland of Ungdong and Myeongji.

  • We have developed a vision based crack detection system and algorithm to inspect base side of bridges. After human operator decides from vision images captured if lines on base side are cracks or dirt, our algorithm finds automatically the length, the width and the shape of cracks. The system has been tested with a robot extender on a truck in real environment and has been proved to be very useful to reduce inspection cost as well as the data management.

  • Science fiction films touch coming-future themes, particularly those referring specifically to futuristic technology and its influence over human life. Dealing with the resistance of the replicants in the approaching millennium, Blade Runner brings the feat of modern civilization into doubt through the image of the dystopian future. In Blade Runner, a city is filled with waste, pollution, and dirt and a corrosive rain falls from the polluted clouds. Adorno criticizes contemporary society and its civilization. Characterizing advanced capitalist society by its total administration penetrating into every sphere of life, he contends that modern society promotes alienation, atomization, conformism, and fatalism. Blade Runner provides a chance to contemplate the problems of modern society, proposed by Adorno's critical works. Therefore, this paper attempts to analyze futuristic characteristics described in the film with Adorno's critique of modern society.

  • This study attempts to research and analyze the khaki color, which is regarded to be the most difficult to be conveyed in general. In so doing, this study aims to contribute to better understanding of the khaki color. First of all, I research definitions of the khaki, which originates from the color of "dirt", and set a boundary of this color. Second, I examine the pigments from plants that produce the color of khaki. In addition, based on the survey results and the color scheme dictionary, I analyze the characteristics of the khaki, from the cognitive perspective, and its attributes as a neutral color.

  • CWM(Coal Water Mixture) is a mixed fuel that consists of coal, water and additives. The main advantages of CWM are reducing the oil consumption and the air pollution materials such as flyash, dirt, and $SO_x$. This paper presented a case study for the economic feasibility analysis of changing an existing coal-oil power plant to a CWM power plant. The economic analysis of changing a coal-oil power plant to a CWM power plant was based on the total annual incremental costs of two power plants. We found that this project was economically and environmentally acceptable.

  • The purpose of this study is to develop a method to evaluate solubility parameter interactions of cosmetic ingredients in formulations. This experimentation relates to the fabrication of new multi-layer cleansing oil which can remove make-up products such as lipstick, foundation, mascara, eye shadow, etc., and also can wash away dirt and sebum from the skin just in one stage process. Solubility parameter and specific gravity of various cosmetic ingredients are measured to explain the cleanliness of interface, detergency of make-up cosmetics on the skin surface. The results suggest that it is possible for cosmetic chemists to use solubility parameter of cosmetic materials for fabrication of new formulation of 3-layer cleansing oil.

  • Management of Swimming pool is focused on Swimming pool samitation in relation with chlorination of swimming water and potable water, disposal of waste and excrement within the boundry of swimming pool that may be summerised as follows: 1. Chlorination of Swimming Water Residual chlorine must be kept within the range of $0.4\~0.6 mg/l$ and in case of chloramine should be $0.7\~1.0mg/l$ while swimming pool is in operation 2. Chlorination of potable Water Residual chlorine must be kept within the rangs of $0.2\~04 mg/l$ at all time 3. Disposal of litters must be kept in the water tight waste bin with fitted lid, and waste should not be overflow -out of the bin. When waste in landfilled, the sufficient amount of cover material should be used daily. 4. Disposal of excrement Toilet must be water-flush type. However, The establishment of pit latrine is unavoidable the excrement must be covered with lime or dirt so that excrement should not be exposed to air.

  • This research aims to study the changes In gastrointestinal function attributed to aging In human. The thresholds for recognition and detection of flavors became elevated and salivary gland acinar cells decreased in the old age. But most esophageal function remained relatively Intact. Although gastric emptying time has been slowed with aging, the total intestinal transit time did not differ. Atropic gastritis due to H. pylori in old man decreased secretion of acid and Intrinsic factor and absorbability of calcium and iron. Pancreatic secretion is droned in older persons. Prevalence of gallstones rised with age. Liver size and portal blood flow decreased significantly with age. Mucosal surface area has been reported to be slightly diminished in the aging man. Glucose transporters decreased and Insulin tolerance Increased. Absorption of aromatic amino acid is diminished with age. Dietary protein In that aging human increased fecal nitrogen excretion. Vitamin A tolerance increased. Vitamin D receptor concentration decreased and resistance to 1,25-(OH)2D3 action increased. Permeability of aging small Intestine Increased. Zinc balance dirt not differ Copper absorption appeared not to be significantly affected by age. Neurotensin secretion decreased thus slowed colonic peristaltic movements and Intestinal mucosal growth.
