Definition and Classification of Healthy Foodservice for Business and Industry
This study was designed to provide useful information for South Korean foodservice management in developing and implementing healthy menus. Using in-depth interviews and data from previous studies, this study was conducted to characterize and classify healthy food. In-depth interviews were conducted with six people in charge of menu management at six different foodservice companies in South Korea. A healthy menu was defined as “a menu with increased nutrition value and/or decreased unhealthy factors by changing to ingredients or cooking methods.” Under the definition, four categories of healthy menus were defined as containing: “nutritionally-fortified food,” “natural food,” “organic food,” and “medicinal food.” Examples of unhealthy food or products included additives such as “MSG,” “use bad fats,” and “over processed foods.
Video-Based Stylized Rendering using Frame Difference
In this paper, we suggest video based stylized rendering using frame difference. Stylized rendering using video frame has a temporal problem that occurs a difference between the previous and current frame. To reduce the temporal problem, we generate reference maps using temporal frame difference in correction and rendering steps. A correction method using reference maps can be reduced flickering effect caused by frame difference between the previous and current frame. We use a background map, an average map, and a quadtree-based summed area table as reference maps. Among these reference maps, the method using quadtree based summed area table can completely remove a flickering and popping effect. Also, a post-blurring method using bilateral filtering can be represented smooth, stylized rendering by removing unnecessary noise. Suggested stylized rendering system can be used in various fields such as visual art, advertisement, game and movie for stylized image contents generation
Measurement of the Background Activities of a 100Mo-enriched powder sample for AMoRE crystal material using a single high purity germanium detector
The Advanced Molybdenum-based Rare process Experiment (AMoRE) searches for
neutrino-less double-beta (0{\nu}\b{eta}\b{eta}) decay of 100Mo in enriched
molybdate crystals. The AMoRE crystals must have low levels of radioactive
contamination to achieve low background signals with energies near the Q-value
of the 100Mo 0{\nu}\b{eta}\b{eta} decay. To produce low-activity crystals,
radioactive contaminants in the raw materials used to form the crystals must be
controlled and quantified. 100EnrMoO3 powder, which is enriched in the 100Mo
isotope, is of particular interest as it is the source of 100Mo in the
crystals. A high-purity germanium detector having 100% relative efficiency,
named CC1, is being operated in the Yangyang underground laboratory. Using CC1,
we collected a gamma spectrum from a 1.6-kg 100EnrMoO3 powder sample enriched
to 96.4% in 100Mo. Activities were analyzed for the isotopes 228Ac, 228Th,
226Ra, and 40K. They are long-lived naturally occurring isotopes that can
produce background signals in the region of interest for AMoRE. Activities of
both 228Ac and 228Th were < 1.0 mBq/kg at 90% confidence level (C.L.). The
activity of 226Ra was measured to be 5.1 \pm 0.4 (stat) \pm 2.2 (syst) mBq/kg.
The 40K activity was found as < 16.4 mBq/kg at 90% C.L.Comment: 20 pages, 6 figures, 5 table
Volumetric Lung Nodule Segmentation using Adaptive ROI with Multi-View Residual Learning
Accurate quantification of pulmonary nodules can greatly assist the early
diagnosis of lung cancer, which can enhance patient survival possibilities. A
number of nodule segmentation techniques have been proposed, however, all of
the existing techniques rely on radiologist 3-D volume of interest (VOI) input
or use the constant region of interest (ROI) and only investigate the presence
of nodule voxels within the given VOI. Such approaches restrain the solutions
to investigate the nodule presence outside the given VOI and also include the
redundant structures into VOI, which may lead to inaccurate nodule
segmentation. In this work, a novel semi-automated approach for 3-D
segmentation of nodule in volumetric computerized tomography (CT) lung scans
has been proposed. The proposed technique can be segregated into two stages, at
the first stage, it takes a 2-D ROI containing the nodule as input and it
performs patch-wise investigation along the axial axis with a novel adaptive
ROI strategy. The adaptive ROI algorithm enables the solution to dynamically
select the ROI for the surrounding slices to investigate the presence of nodule
using deep residual U-Net architecture. The first stage provides the initial
estimation of nodule which is further utilized to extract the VOI. At the
second stage, the extracted VOI is further investigated along the coronal and
sagittal axis with two different networks and finally, all the estimated masks
are fed into the consensus module to produce the final volumetric segmentation
of nodule. The proposed approach has been rigorously evaluated on the LIDC
dataset, which is the largest publicly available dataset. The result suggests
that the approach is significantly robust and accurate as compared to the
previous state of the art techniques.Comment: The manuscript is currently under review and copyright shall be

The Rhizomes of Acorus gramineus and the Constituents Inhibit Allergic Response In vitro and In vivo
The rhizomes of Acorus gramineus have frequently been used in traditional medicine mainly for sedation as well as enhancing brain function. In this study, the anti-allergic activity of A. gramineus was investigated. The 70% ethanol extract of the rhizomes of A. gramineus was found to inhibit the allergic response against 5-lipoxygenase (5-LOX)-catalyzed leukotriene (LT) production from rat basophilic leukemia (RBL)-1 cells and β-hexosaminidase release from RBL-2H3 cells with IC50's of 48.9 and >200 μg/ml, respectively. Among the 9 major constituents isolated, β-asarone, (2R,3R,4S,5S)-2,4-dimethyl-1,3-bis (2',4',5'-trimethoxyphenyl)tetrahydrofuran (AF) and 2,3-dihydro-4,5,7-trimethoxy-1-ethyl-2-methyl-3-(2,4,5-trimethoxyphenyl)indene (AI) strongly inhibited 5-LOX-catalyzed LT production in A23187-treated RBL-1 cells, AI being the most potent (IC50=6.7 μM). Against β-hexosaminidase release by antigen-stimulated RBL-2H3 cells, only AI exhibited strong inhibition (IC50=7.3 μM) while β-asarone and AF showed 26.0% and 39.9% inhibition at 50 μM, respectively. In addition, the ethanol extract of A. gramineus showed significant inhibitory action against the hapten-induced delayed hypersensitivity reaction in mice by oral administration at 200 mg/kg. Therefore, it is suggested that A. gramineus possesses anti-allergic activity and the constituents including β-asarone and AI certainly contribute to the anti-allergic activity of the rhizomes of A. gramineus.This study was financially supported by the research fund of Studies on the Identification of the Efficacy of Biologically Active Components from Oriental Herbal Medicines from Korean Food and Drug Administration (2009-2011) and post-BK21 project from the Ministry of Education, Korea.OAIID:oai:osos.snu.ac.kr:snu2013-01/102/0000001731/23SEQ:23PERF_CD:SNU2013-01EVAL_ITEM_CD:102USER_ID:0000001731ADJUST_YN:NEMP_ID:A000864DEPT_CD:371CITE_RATE:.794FILENAME:bt_asarone.pdfDEPT_NM:제약학과EMAIL:[email protected]_YN:YCONFIRM:
Significance of Brainstem Auditory Evoked Potentials as an Initial Evaluation for Dizziness
The authors performed brainstem auditory evoked potential (BAEP) studies
on 207 patients with dizziness symptoms, and evaluated the significance of BAEPs in
differentiating among various causes of dizziness.
The results showed abnormal BAEPs, which were suggestive of brainstem dysfunction,
in 20 of 106 of the probable vertebrobasilar transient ischemic attack (VB TIA)
group (18.8%), and in 12 of 101 of the vague dizziness (VD) group (11.8%). Additionally,
there were abnormal BAEPs, which were suggestive of the end-organ dysfunction,
in 4 of 101 of the VD group (3.9%). When we analysed 32 abnormal BAEPs
suggestive of brainstem dysfunction, the most frequent BAEP abnormality was the prolongation
of I-III interpeak latency OPt) (53.1%). Prolonged I-V IPL was the second
most common abnormality (28.2%), with III-V IPL prolongation occurring less commonly
(18.7%). The follow-up studies of abnormal BAEPs showed that the initial abnormal
BAEPs reverted to normal in three of six patients, but in the remaining three
the abnormality persisted during follow-up period of one to four years.
Therefore, it is concluded that BAEP tests would be useful in differentiating the
dizziness as one of those symptoms of brainstem dysfunction from non-brainstem syndrome
which mimics it
Closed Strings Interacting with Noncommutative D-branes
Closed string dynamics in the presence of noncommutative Dp-branes is
investigated. In particular, we compute bulk closed string two-point scattering
amplitudes; the bulk space-time geometries encoded in the amplitudes are shown
to be consistent with the recently proposed background space-time geometries
dual to noncommutative Yang-Mills theories. Three-point closed string
absorption/emission amplitudes are obtained to show some features of
noncommutative Dp-branes, such as modified pole structures and exponential
phase factors linearly proportional to the external closed string momentum.Comment: 18 pages, 3 figures; v2. references added, minor corrections; v3.
