Sensors of Landsat detect different objects with different waves, so the range of water quality conditions can be accurately checked, and their images can be displayed in colors. The present study was conducted to measure the degree of clearness and depth and to detect elements from the surface water of Hwajinpo Lake. Based on these results, water quality of the lake was analyzed, and the range of water quality was drawn graphically. According to comparison outcomes, the new technique of detecting water elements from DN of Landsat TM images and drawing the range of water quality produced a far more accurate pattern for a wide area than the direct measurement. To display the pattern more clearly, the stretching technique in particular was very effective in the pattern analysis.

In this paper, a new energy recovery circuit for AC PDP(Plasma Display Panel) is proposed to decrease a sustain voltage and voltage stress on switching elements. In the proposed circuit, two auxiliary capacitors are connected directly to the power source through switching elements and inductors when ground potential is supplied to the panel. Therefore, the voltage across auxiliary capacitors can be increased by turns over the half of the source voltage. Because the intrinsic capacitance of PDP is charged sufficiently from the auxiliary capacitors, the level of sustain voltage and the voltage stress on the switching devices are decreased. To verify the validity of the proposed energy recovery circuit, computer simulations using PSpice program are carried out.

Using the modified DEM (Discrete Element Method), which we proposed in order to improve the accuracy of the simulation, soil behavior and reaction by lugs of rotating wheel and a soil cutting process by a high speed blade were calculated and compared with experimental data. The DEM is one of computational mechanics, where the object body is supposed as an assembly of small particles called elements and not a continuum as in the case of FEM. We can easily treat some discrete phenomena such as cracking, separating and sliding by the DEM. We had to modify the original mechanical model, which induced too free movement of elements, adding a tension spring, which would display the role of soil adhesion. The results of DEM simulations were successful from both the soil behavior and reaction points of view.

Effects of aging treatment of doped-MgO electron emission layer on luminance efficiency of ac-PDP were investigated in this study. Morphological and luminance efficiency with aging treatment were examined, especially with emphasis on the effects of doping elements. The results indicate that the luminance efficiency of test panels depends on the type of doping elements used for MgO and that may be due to the redeposition of MgO during glow discharge.

The space is generally the discontinuation space without being understood agreed by some people. In this time, expressing transparency has various significances in furniture design because modern people want transparence and space due to the complication, numerous unreasonable facts and the lack of honesty in the society. Philip Johnson's Glass House in 1946 influenced architecture, interior, furniture and life article to use transparent materials and space that is being until currently development. The transparency which comes to be preferred clearly means to develop the society continuously. It can be more liberal, honest, and transparent society. The trend appeared in furniture design has meaning as the representative product. This research has perceptional transparency(visible transparency), abstract transparency through space(phenomenal transparency), overlap of surface element, display of line element, image using dot, and changing the image of various spaces.

The FISPACT-II inventory simulation platform is a modern computational tool with advanced and unique capabilities. It is sufficiently flexible and efficient to make it an ideal basis around which to perform extensive simulation studies to scope a variety of responses of many materials (elements) to several different neutron irradiation scenarios. This paper briefly presents the typical outputs from these scoping studies, which have been used to compile a suite of nuclear physics materials handbooks, providing a useful and vital resource for material selection and design studies. Several different global responses are extracted from these reports, allowing for comparisons between materials and between different irradiation conditions. A new graphical output format has been developed for the FISPACT-II platform to display these "global summaries"; results for different elements are shown in a periodic table layout, allowing side-by-side comparisons. Several examples of such plots are presented and discussed.

Quality is distinguished from the other important management indicators, cost and profitability, by the features of its far longer history and of common concern to both manufacturer and customer. We may say from this that quality has a far more human aspect than either cost or profitability. We stress the importance of establishing “quality culture.” But we do not commonly use the terms of “cost culture” or “productivity culture.”In addition, we know from our experiences that improving quality by creative methods can lead to lower cost and higher productivity, although the converse is not necessarily true. In the Maslow's hierarchy of human needs, it is known that the character of human needs changes from extrinsic and material ones at lower levels to intrinsic and mental or spiritual ones at higher levels. We know from our experience that employee satisfaction is closely linked with quality, which is of more human nature and can further be deployed into the detailed elements of quality. The leaders and managers should positively display leadership and respond to the efforts of the subordinates. Without these managerial leadership and efforts, it is almost impossible to provide essential and true customer satisfaction. They are the indispensable elements for business excellence.

Functional interpretation of noncoding genetic variants associated with complex human diseases and traits remains a challenge. In an effort to enhance our understanding of common germline variants associated with lung cancer, we categorize regulatory elements based on eight major cell types of human lung tissue. Our results show that 21.68% of lung cancer-associated risk variants are linked to noncoding regulatory elements, nearly half of which are cell type-specific. Integrative analysis of high-resolution long-range chromatin interactome maps and single-cell RNA-sequencing data of lung tumors uncovers number of putative target genes of these variants and functionally relevant cell types, which display a potential biological link to cancer susceptibility. The present study greatly expands the scope of functional annotation of lung cancer-associated genetic risk factors and dictates probable cell types involved in lung carcinogenesis.

The present study is focused on investigating the subjective viewpoint of users favoring Galaxy phones as an element for emotional experience designs, and Q methodology used for the study of subjectivity has revealed 3 types. The first type is a type pursuing reasoned actions with high expectations for the emotional quality through direct and indirect experiences of Galaxy phones. They were shown to place an emphasis on portability and usability while having a low preference for the shape of external forms and materials. The second type is a type pursuing planned actions with an emphasis on individual subjective perceptions as well as both of physical sensation and usability. They were distinguished as a type preferring pleasure and efficiency experienced by its use. The third type is a type pursuing differentiated personalities with an emphasis on messages they want to deliver to other people through the products owned by an individual. They were identified as a type emphasizing display of personalities through differentiation in aesthetic elements.

Using the theoretical model of Auger electron emission, effects of MgO properties which include band gap energy, escape probability, gas ion, and doping elements on the yield of secondary electron emission were examined. The results indicated that the band gap of MgO must be decreased and escape probability must be enhanced in order to increase the yield of secondary electrons from Xe ions and that may proved to be a critical for achieving high luminance efficacy in ac-PDPs.
