This study explores a value chain structure of TV program including news, drama, and comedy. The purpose of this research focused on factor analysis and the relationship among viewer's program selection motivations. This research explores correlation between personal value and viewing motivation. This study was to identify the value structure of respondent on TV program(news, drama, comedy) based on means-end chain theory. The research used structured APT laddering questions and 251 data was analysed. Through such analysis, category difference by stage and relationship difference were identified and hierarchical value map was compared. There are four different value ladders: first is attributes, functional consequences, psychological consequences, and final value. The result shows that on news program the basic function is viewers are want to visual factor and quickly acquire social news and they pursue a value of personal social relationship. Whereas, on drama program, the viewers are reflected by around person, and they selected a program based on closed related person. In addition, the viewers are influenced by program's social nomination, production's brand in drama, and performer's nomination, producer and program prominence on comedy. The program selection is highly correlated on program selection's credibility, vital energetic life, and social relationship. The results shows that there was no significant difference between low involvement group and high involvement group for main category involvement group respondents.

The Lord of Mayan society was a person who was thought to be able to understand phenomena in the universe. And also the Lord could realize these activities of heaven on Earth through ritual. But the manifested ritual function of lordship was very different depends on Classic and Postclassic period. The Classic Mayan rituals were closely related to personal dignity, specially royal blood tradition meanwhile the Postclassic Mayans focused on public function of ritual. The ritual sacrifices of blood letting from their own body, manifested in Yaxchilan Lintel 24, 25 and 17, were focused on royal family's activity, showing the dignity of royal blood. The same ritual about the birth of family successor was observed at the Structure 5C4 from Postclassic ruin of Chichen Itza. However, this scene in focus, was two representative men and the answer of ancestor, not a special person. Also at the Lintel 1 of Temple of Four Lintels it was observed names of four Lords of Chichen Itza, their relationship, their action of firing to dedicate temple instead of writing long history of great royal family. All above shows that during Postclassic period the lords preferred a public function of their lordship than to dignify some royal persons through ritual.

This study focused on the plane and side drape coefficients of weft knitted fabrics as a function of knit structure, stitch density, and stiffness. Fifteen weft knitted fabrics are produced with five different structures (interlock, single pique, royal interlock, cross miss interlock, and mock royal interlock) and three different gauges (7G, 10G, and 12G). Five knit structures were the application of knit, tuck, and miss stitch on the basis of interlock of the double knit fabric For this purpose, three-dimensional shapes of the draped sample were obtained by using a drapability tester which can record the contour line coordinates of a projected plane drape. Then, projected shapes of the plane and side drape were derived from those three-dimensional ones to review the relationship between plane drape coefficients and side ones. It was found that the theoretical values of plane and side drape coefficients depending on the change of deflection angles fit to their experimental ones. A5 a result of a regression analysis of the relationship between plane and side drape coefficients, the relationship could be expressed as $y=0.5838x-0.0065x^2+9.03{\times}10^{-5}x^3$. In case of mean of drape coefficient, it was increased according to the rule of that the more tuck and miss stitch overlap. A high degree of correlation was found between stiffness and drape coefficient. The regression equation of drape coefficient($y$) can be represented by $y=y=\sqrt[3]{Stiffness}-10.72$.

Purpose: This paper investigated the relationship between market competition and firm valuation error. Furthermore, Additional analyses were made according to the quality of financial reports and the listed market. Through the process we confirm to the impact of competition on the capital market. The purpose of this study is to analyze the impact of competition on valuation errors. The preceding studies did not provide a consistent results of the effects of competing functions on the capital market. One view is that the competition could mitigate the information asymmetry, and the other is that monopolistic lessens the manager's involvement in financial reporting. This study is intended to expand the prior study by analyzing the impact of competition on the capital market and on the valuation of investors. Research design, data, and methodology: The analysis was conducted on 12,031 samples over 11 years from 2008 to 2018 using data from market in Korea. Here the valuation error was measured by the research methodology of Rhodes-Kropf, Robinson and Viswanathan (2005), and competition measured by Herfindahl-Hirschman Index multiplied by (-1), and Concentration Ratio by (-1). Results: We confirm that the positive relationship between competition and the valuation error. In addition, we also found that the positive relation between competition and valuation error was in cases of low discretionary accruals and the KOSDAQ market. This means that the net function of competition does not mitigate valuation errors. Conclusions. This study has the following contributions when compared to prior research. First, the relevance between the level of competition and the valuation of the entity was confirmed. The study by Haw, Hu and Lee (2015) suggested that monopolistic industry of analysts' forecast is more accurate due to lower the variability in earnings. This study magnified it to confirm that monopolistic lessen information uncertainty in valuation. Second, the study on valuation errors was expanded. While the study on the effect of valuation errors on the capital market is generally relatively active, it is different that competition degree has analyzed the effect on valuation errors amid the lack of research on the effect on valuation errors.

To elucidate structure-function relationship of polysaccharide from Angelica gigas, the AGE-2c-I was purified by two successive chromatography steps. AGE-2c-I showed a potent anti-complementary activity in a dose-dependent manner. AGE-2c-I with a molecular weight of 140 kDa comprised four monosaccharides and 13 glycosyl linkages, and strongly reacted with ${\beta}$-glucosyl Yariv reagent. For the fine structure analysis of AGE-2c-I, it was sequentially digested by exo-arabinofuranosidase and endo-galactanase. The results indicated that AGE-2c-I was a typical RG-I polysaccharide with side chains such as highly branched ${\alpha}$-arabinan, ${\beta}$-($1{\rightarrow}4$)-galactan and arabino-${\beta}$-3,6-galactan. To characterize the active moiety of AGE-2c-I, the anti-complementary activities of AGE-2c-I and its subfractions were assayed. It was observed that the anti-complementary activity of AGE-2c-I was due to the entire structure that resembled RG-I. In addition, arabino-${\beta}$-3,6-galactan side chain (GN-I) in AGE-2c-I probably plays a crucial role in the anti-complementary activity, whereas ${\alpha}$-arabinan side chain (AFN-I) consisting of 5-linked Araf and 3,5-branched Araf partially contributes to the activity.

This study proposes a load identification for the safety monitoring of the steel structure based on measured strain data. Instead of parameterizing the stiffness of structure in the existing system identification researches, the loads on a structure and a matrix (the unit strain matrix) defined by the relationship between strain and load on structure are parameterized in this study. The error function is defined by the difference between measured strain and strain estimated by parameters. In order to minimize this error function, the genetic algorithm which is one of the optimization algorithm is applied and the parameters are found. The loads on the structure can be identified through the founded parameters and measured strain data. When the loads are changed, the unmeasured strains are estimated based on founded parameters and measured strains on changed state of structure. To verify the load identification algorithm in this paper, the static experimental test for 3 dimensional steel frame structure was implemented and the loads were exactly identified through the measured strain data. In case of loading changes, the unmeasured strains which are monitoring targets on the structure were estimated in acceptable error range (0.17~3.13%). It is expected that the identification method in this study is applied to the safety monitoring of steel structures more practically.

The structure zone model has been used to provide an overview of the relationship between the microstructure of the films deposited by PVD and the most prominent deposition condition.s. B.AMovchan and AV.Demchishin have proposed it firstls such model. They concluded that the general features of the resulting structures could be correlated into three zones depending on $T/T_m$. Here T m is the melting point of the coating material and T is the substrate temperature in kelvines. Zone 1 ($T/Tm_) is dominated by tapered macrograins with domed tops, zone 2 ($O.3) by columnar grains with denser boundaries and zone 3 ($T/T_m>O.5$) by equiaxed grains formed by recrystallization. J.AThomton has extended this model to include the effect of the sputtering gas pressure and found a fourth zone termed zone T(transition zone) consisting of a dense array of poorly defined fibrous grains. R.Messier found that the zone I-T boundary (fourth zone of Thorton) varies in a fashion similar to the film bias potential as a function of gas pressure. However, there has not nearly enough model for explaining the change in morphology with crystal orientation of the films. The structure zone model only provide an information about the morphology of the deposited film. In general, the nucleation and growth mechanism for granular and fine structure of the deposited films are very complex in an PVD technique because the morphology and orientation depend not only on the substrate temperature but also on the energy of deposition of the atoms or ions, the kinetic mechanism between metal atoms and argon or nitrogen gas, and even on the presence of impurities. In order to clarify these relationship, AI and Mg thin films were prepared on SPCC steel substrates by PVD techniques. The influence of gas pressures and bias voltages on their crystal orientation and morphology of the prepared films were investigated by SEM and XRD, respectively. And the effect of crystal orientation and morphology of the prepared films on corrosion resistance was estimated by measuring polarization curves in 3% NaCI solution.

This paper treated what are congressional records which are one of core fields of national records and what kind of significant records they have. The characteristics of "substantive records" of the institution among public records are as follows: firstly, their contents depend on the inherent function of the institution; secondly, their types differ by the character of basic unit(member); thirdly, their sources are determined by the character of institution. Starting from the above points of view, the contents, characteristics, main sources, and types by sources of congressional records were presented. They are summarized as follows. In Chapter 2, the substantial records, which document the intrinsic function of congress on the basis of analyses of inherent function and structural uniqueness of congress have natures of which the contents are "legislative records", "oversight records", and "political activity records" starting from the inherency of congress as the people's representation. The typical natures of congress records are related with the specialty that the basic unit of congress structure is an individual congressman as an indepent national institution and congress is a council of these congressmen. Firstly, the records of congressmen as basic member of congress are the national records with the type of personal records. Secondly, "council records" produced by the council (commettee and main conference), which have evidencial and informative value for decision making through the process of investigating, discussing and voting bill and policy (item) of the basis for national management, are very special kind of records, such as item records, decision records, journal records, and congress assistant records. Because congressmen and councils composing congress have an equal inter-relationship in the structure of congress, the main sources of congress records are an individual congressman and all the councils. In chapter 3, the contents and sorts of main records are discribed, centering around congressmen and councils as the main sources of congress records. In chapter 4, the management of records of congressmen is issued as an urgent subject for the management of congress records, instead of conclusions.

Starch was isolated from turnip (Brassica rapa L.), and to elucidate the structure-function relationship its structural and physical properties were characterized. Morphological structure of the starch was analyzed by SEM (Scanning Electron Microscopy). Most of the starch granules were spherical in shape with diameter ranging from 0.5-10mm. Apart from larger granules ($<10\;{\mu}m$) which dominated the population size of turnip starch, significant amount of small ($0.5-2\;{\mu}m$) and mid-size granules (${\sim}\;{\mu}m$) were also detected. It was revealed that presumably, erosion damages occurred due to the attack of amylase-type enzymes on the surface of some granules. Branch chain-length distribution was analyzed by HPAEC (High-Performance Anion-Exchange Chromatography). The chain-length distribution of turnip starch revealed a peak at DP12 with obvious shoulder at DP18-21. The weight-average chain length ($CL_{avg}$) was 16.6, and a large proportion (11.8%) of very short chains (DP6-9) was also observed. The melting properties of starch were determined by DSC (Differential Scanning Calorimetry). The onset temperature ($T_o$) and the enthalpy change (${\Delta}H$) of starch gelatinization were $50.5^{\circ}C$ and 12.5 J/g, respectively. The ${\Delta}H$ of the retrograded turnip starch was 3.5 J/g, which indicates 28.2% of recrystallization. Larger proportion of short chains as well as smaller average chain-length can very well explain relatively lower degree of retrogradation in turnip starch.
