Since the advent of Linked Data (LD) as a method for building webs of data, there have been many attempts to apply and implement LD in various settings. Efforts have been made to convert bibliographic data in libraries into Linked Data, thereby generating Library Linked Data (LLD). However, when memory institutions have tried to link their data with external sources based on principles suggested by Tim Berners-Lee, identifying appropriate vocabularies for use in describing their bibliographic data has proved challenging. The objective of this paper is to discuss the potential role of Linked Open Vocabularies (LOV) in providing better access to various open datasets and facilitating effective linking. The paper will also examine the ways in which memory institutions can utilize LOV to enhance the quality of LLD and LLD-based ontology design.

I. Objectives In order to examine the immunoresponse of host cells to Enterococcus faecalis, this in vitro study monitored the production of Interleukin-2(IL-2), Interleukin-4(IL-4) and Transforming growth $factor-{\beta}1(TGF-{\beta}1)$ in human lymphocytes. II. Materials and methods Enterococcus faecalis(ATCC29212) strains were used in this study. Strains were grown in 1-liter cultures in 85% N2-10% H2-5% $CO_2$chamber for 3 days at $37^{\circ}C$. The medium used was 3.7% brain heart infusion broth. Bacterial cells harvested from 1-liter cultures were washed, suspended in 20ml of phosphate-buffered saline(PBS). Suspensions of bacterial cells were disrupted by sonication on ice for 5 min. Protein concentration was determined by the Bicinchoninic acid(BCA) protein assay.(omitted)

본 논문에서는 PCA에 의한 특징추출과 k-NN과 SVM에 기반을 계층구조의 분류기에 의한 유도전동기의 고장진단 알고리즘을 제안한다. 제안된 방법은 k-NN에 의해 선형적으로 분류 가능한 고장패턴을 분류한 후, 분류가 되지 않는 부분을 커널 함수에 의해 고차원 공간으로 입력패턴을 매핑한 후 SVM에 의해 고장을 진단하는 계층구조를 갖는다. 실험장치를 구축한 후, 다양한 부하에 대하여 몇몇의 전기적 고장과 기계적 고장 하에서 획득한 데이터를 이용하여 제안된 방법의 타당성을 검증한다.

A total of 47 beer samples, produced in Korea. Were analyzed for their N-nitrosamine levels by gas chromatography-thermal energy analyzer. N-nitrosodimethyamine(NDMA) was detected in 35 of 47 sam-ples analyzed. The range of levels was 0~7.2$\mu\textrm{g}$/kg while the average was about 0.9mg/kg. The identity of NDMA was confirmed by mass spectrometry. Samples which were found only NDMA before nitrosation were detected to include N-nitrosopyrroidine(45$\mu\textrm{g}$.kg) and N-nitrosomorpholine(4$\mu\textrm{g}$/kg) as well as NDMA(837$\mu\textrm{g}$/kg)

In this paper, fabricated is a motion capture and attitude detection system for Head Mounted Display HMD composed of three low-price and low-grade micro gyroscopes and a micro-controller, To calculate attitude of a body, modified INS algorithm is used. Because the micro gyroscope has much bias drift error, scale factor error, and run-to-run bias error, the motion of a body can not be measured exactly if the general INS algorithm and micro gyroscopes are used. To reduce the errors, three accelerometers can be used. In this case, however, the size and power consumption become too large to use in HMD system. The modified INS algorithm use the grid map and the characteristics of the human motions.

Long-term nonstationary oscillations (NSOs) are commonly observed in hydrological and climatological data series such as low-frequency climate oscillation indices and precipitation dataset. In this work, we present a stochastic model that captures NSOs within a given variable. The model employs a data-adaptive decomposition method named empirical mode decomposition (EMD). Irregular oscillatory processes in a given variable can be extracted into a finite number of intrinsic mode functions with the EMD approach. A unique data-adaptive algorithm is proposed in the present paper in order to study the future evolution of the NSO components extracted from EMD.

Previously, we reported that the n-butanol fraction of Lonicera japonica showed anti-flammatory activity in mice and rats. Several constituents such a loniceroside A and B, flavonoids and iridoids were isolated from this fraction. In this investigation, the anti-inflammatory activity of the major constituents of L. japonica was studied. Loniceroside A, lonicerin and loganin showed anti-inflammatory activity comparable to aspirin.

The dioxygen transfer reaction from $N^5$-ethyl-4a-hydroperoxy-3-methyllumiflavin anion (4a-FlEtOO-) has been extended to isomeric aminophenol systems (1a-4a). O-aminophenol (o-AP, 1a & 2a) and p-aminophenol(p-AP, 3a & 4a) were turned out to be good substrates, whereas m-aminophenol(m-AP, 5a) was not. This is due to the charge location which is not on the carbon bearing the amino group. o-AO's react with 4a-FlEtOO- to give isophenoxazine derivatives (6 & 7) and with p-AP's to produce p-benzoquinone derivatives (8 & 9). The partition coefficients $(k_2/k_3)$ of 1a & 2a were $4.84{\times}10^{-4}\;&\;1.66{\times}10^{-5}M$, respectively and those of methylated aminophenolates, 2a & 4a were 4-10 times greater than nonmethylated substrates, 1a & 3a.
