Structured abstracts have been regarded as an essential information factor to represent topics of journal articles. This study aims to provide an unconventional view to utilize structured abstracts with the analysis on sub fields of a structured abstract in depth. In this study, a structured abstract was segmented into four fields, namely, purpose, design, findings, and values/implications. Each field was compared in the performance analysis of document clustering. In result, the purpose statement of an abstract affected on the performance of journal article clustering more than any other fields. Furthermore, certain types of keywords were identified to be excluded in the document clustering to improve clustering performance, especially by Within group average clustering method. These keywords had stronger relationship to a specific abstract field such as research design than the topic of an article.

This study analyzed features in contemporary men's collection to provide data for characteristics of kitsch in men's collection. The research method was to see background of the concept of kitsch through the domestic and international publications, the Internet, paper. Five designers' collections that have characteristics of kitsch were selected. The range of collection is from the 2000 S/S to 2011 F/W in Men's collection. The results are as follows: kitsch characteristics could be classified by amusements, inappropriateness, satire. First, exaggerative amusements in men's collection appeared exaggerated form, large size, which is ridiculous at the same time. Infantile amusements represents the image of a pure concentric matching accessories such as toys to the children express. sensual amusements reveals the sexual instincts and desires and people can feel satisfaction through sensual amusements. Second, inappropriateness is characteristic of kitsch to escape from normal life. Clothing does not fit the body and destroyed the design or design of this feature appears. It looks clumsy and strange. Inappropriateness characteristic in men's collection can be divided into inadequate performance and sexual inappropriateness. Third, satire can be divided into resistant satire, imitative satire, and popular satire. Resistance satire with anti-social tendencies through their clothing is achieved by expressing their needs. It was affected by sub-culture like Hippie or Punk. Imitative satire is to imitate other culture, customs and race. It is to resolve complaints through the consumption of things in disparities of wealth and materialism in the society. Popular satire is to express emotions that are free using materials that can recycling like can, bottle or paper.

Carbon tips were grown on Si cantilevers by applying an electron beam to them directly with Scanning Electron Microscope. A carbon tip was fabricated by aligning the electron beam directly down the vertical axis of Si cantilever and then irradiating a single spot on the cantilever for a proper time in the dominant atmosphere of residual gases generated by the oil of the diffusion pump. A number of control parameters for SEM, including exposure time, acceleration voltage, emission current, and beam probe current, were allowed to make various aspect ratio feature. The growth of carbon tips was not affected by the surface morphology of substrates. We could acquired the tip whose effective length is 0.5 $\mu\textrm{m}$, bottom diameter is 90 nm and cone half angle $3.5^{\circ}$ The growth technique of the high aspect ratio carbon tips on the tip-free cantilevers is available to reduce the complexities of fabricating sub-micron scale tips on the PZT thin film actuator integrated AFM cantilevers.

This study is to standardize framework data model in facility area. This study focuses on standization of application oriented data model in facility management and other facility applications. In order to outline the framework data model in facility area, building and cultural sub-themes which have been proposed in a previously conducted research have initially been considered. Also various international and domestic standards in framework data for facility area have been analyzed to identify appropriate feature classes and types. In order to avoid future conflicts, many facilities experts from various facility areas including facility database and facility manarement have provided their inputs in this study based on their viewpoints and prospects. As a results of this study, we are developed to features and data model or framework data in facility area.

The aim of this study is m inquire the features of preservation and utilization of traditional buildings landscape through the effort of civics and public institution. Kawagoe is 30km from Tokyo and keeps the history and culture of Edo period. The tourism feature of the Ichibangai area which has the traditional warehouse(Kurazukuri) landscape is that the rate of old tourists from nearby regions is high and the one day trip is majority. The most tourists have visited many times, but they have spent small sum of money. The tourism activation of Ichibangai area is the result of the cooperation and effort of public institution, civic organization, and civics. The public institutions have the institutional support system has established which is including the designation of cultural assets, ordinance enactment, tax exemption, repairing charges support, public hearing, construction of tour network. The residents of the Ichibangai area have contributed to preserving the traditional landscape and activating tourism through their own organizations and meetings for a long time. And the roles of various committees which have leaded close cooperation relations between civics and public institution are activated.

The objective of the research is to automatically recognize railway objects from MLS data in which 9 key objects including terrain, track, bed, vegetation, platform, barrier, posts, attachments, powerlines are targeted. The proposed method can be divided into two main sub-steps. First, multi-scale contextual features are extracted to take the advantage of characterizing objects of interest from different geometric levels such as point, line, volumetric and vertical profile. Second, by considering contextual interactions amongst object labels, a contextual classifier is utilized to make a prediction with local coherence. In here, the Conditional Random Field (CRF) is used to incorporate the object context. By maximizing the object label agreement in the local neighborhood, CRF model could compensate the local inconsistency prediction resulting from other local classifiers. The performance of proposed method was evaluated based on the analysis of commission and omission error and shows promising results for the practical use.

Earlier research works focused on the seasonal patterns and bio-geochemical processes in sand dunes, and the satellite data and aerial photographs have been used only as a backdrop or for the multi-temporal delineation of sand dune area. In order to find the optimal way to extract features' characteristics, Gimnyeong sand dune area was selected as a study site. Field works have been carried out three times to collect ground control points and sand samples for laboratory analyses. The texture of sand dune is classified as fine sand, which has been derived from shell fragments. The sand dune penetrated into the island from northwest to southeast direction. An aerial photograph was re-sampled into one-meter resolution and rectified with software including Erdas Imagine and ENVI. Sub-scenes were chosen as samples for sand dune, urban area and rural area. K-group non-parametric analysis had been done for the geometric and spectral values of enclosed texture patches. Urban areas proved to have significant smaller patches than the others.

Deep Ca,b,y images obtained from the CTIO 4m Blaco telescope are used to investigate the multiple stellar populations of red giant branch (RGB) and sub-giant branch (SGB) in Galactic globular clusters NGC 6656 and NGC 6723. For NGC 6656, confirming the result of Lee et al. (2009), we find two discrete populations of the RGB stars of which mean color separation is about 0.2 mag in hk[=(Ca-b)-(b-y)] index. Furthermore, we also find the bimodel distribution of the SGB stars in (hk, y) color-magnitude diagram. A new finding is that the (hk, y) color-magnitude diagram of NGC 6723 shows two distinct RGB stars with different calcium abundances of which mean color separation is about 0.12 mag in hk index. This multiple stellar feature has not been observed in previous observation, suggesting that NGC 6723 may also be a possible relic of dwarf galaxies that merged into the Milky Way in the past. Thus our result adds further constraints to the merging scenario of the Galaxy formation. Unfortunately, the split of SGB stars in NGC 6723 is not obvious. We will present some statistical results to compare properties of two populations in two clusters.

We propose MBAP(Multi-rate Broadcast Active Probing) technique to get the right measurements for link quality in Wireless Mesh Network (WMN). Most routing protocols for WMN make use of link quality-aware routing metrics, such as ETX(Expected Transmission Count) and ETT(Expected Transmission Time), while the hop count is usually used in MANET (Mobile Ad-hoc NETwork). A broadcast based active proving technique is adopted in the previous studies to get the ETX or ETT of a link. However this technique does not reflect the multi-rate feature of WLAN because it uses a single fixed transmission rate for broadcast which usually differs from the actual rate used in data transmissions. MBAP overcomes this shortage by exploiting various rate broadcast frames for probing. We implement MBAP on linux system by modifying WLAN driver and related kernel sub-systems. Experimental results show that MBAP can capture link quality more accurately than the existing techniques.

Undecided inference could be regarded as a missing data problem such as MARand MNAR. Under the assumption of MAR, undecided inference make use of logistic regression model. The probability of default for the undecided group is obtained with regression coefficient vectors for the decided group and compare with the probability of default for the decided group. And under the assumption of MNAR, undecide dinference make use of logistic regression model with additional feature random vector. Simulation results based on two kinds of real data are obtained and compared. It is found that the misclassification rates are not much different from the rate of rawdata under the assumption of MAR. However the misclassification rates under the assumption of MNAR are less than those under the assumption of MAR, and as the ratio of the undecided group is increasing, the misclassification rates is decreasing.
