SERVICE DESIGN WITH MACHINE LEARNING BASED ON USER ACTION HISTORY (2020)

With the development of IoT techniques, it become easier to collect users' action data. By analyzing and using those data, consumers and producers will mutually exchange their intelligence and better customize product development processes. This study focuses on the users' daily life, examines a proposed system using sensor shoes with several sensor devices embedded in the insoles, collecting action data of users, extracting their action features, and then issuing some advice to help users train more efficiently. As described herein, a service model uses a backpropagation (BP) network to distinguish users' actions and to extract their action features using Self-organization Map from the presented sensing data. Experiments to confirm the feasibility of the proposed methods are undertaken. With the former result indicating an overall accuracy of 89.61% in distinction of 5 actions: sit, stand, walk, run and jump. The latter results showing that SOM is helpful to classify action feature in detail. After the analysing parameters of each cluster numbers, it is possible to make the action feature visualized by providing a colored cluster map, which makes it easier to compare train periods. Results also show the potential of utilization of data collected by devices to provide personal service.
Anticancer effects of diallyl trisulfide derived from garlic. (2008)

Alk(en)yl sulfides are characteristic flavor components of garlic. Several lines of epidemiological study indicate that the risk of a certain cancer can be prevented by consumption of garlic. In this manuscript, we examined the anticancer property of garlic-derived alk(en)yl sulfides, and the molecular basis especially for diallyl trisulfide which is a major constituent of the garlic oil. Alk(en)yl sulfides with different numbers of sulfur atom (i.e., mono-, di-, and trisulfide) were synthesized and purified (>99%). The anticancer activity of the alk(en)yl sulfides was primarily examined using human colon cancer cells HCT-15 and DLD-1. The growth of the cells was significantly suppressed by diallyl trisulfide, but neither diallyl monosulfide nor diallyl disulfide showed such an effect. The number of cells arrested at G2/M phase, the cells with a sub-G1 DNA content, and the cells with caspase-3 activity were dramatically increased by diallyl trisulfide treatment. Diallyl trisulfide disrupted microtubule network formation of the cells, and microtubule fragments could be seen at the interphase. There was a specific oxidative modification of cysteine residues Cys12 beta and Cys354 beta, forming S-allylmercaptocysteines in the tubulin molecule. These results suggest that diallyl trisulfide is responsible, at least in part, for the epidemiologically proven anticancer effect for garlic eaters.
Femtosecond dispersion compensation with multilayer coatings: toward the optical octave (2006)

Dispersive multilayer coatings have found widespread use, particularly in the compensation of material dispersion in femtosecond oscillators and amplifiers. Other than prism or grating sequences, only chirped mirrors allow for the compensation of a much more general spectral dependence of the dispersion. The current state of the art in ultrabroadband mirror design for dispersion compensation is reviewed. Approaches to expand the utility of chirped-mirror coatings toward the coverage of an even-wider bandwidth beyond the optical octave are discussed.
Mesh-based global motion compensation for robust mosaicking and detection of moving objects in aerial surveillance (2011)

Global Motion Compensation is one of the key technologies for aerial image processing e.g. to detect moving objects on the ground or to generate a mosaick image of the observed area. For this task, it is necessary to estimate and compensate the motion of the pixels between the recorded frames evoked by the movement of the camera. As the camera is statically attached to a flying device such as a quadro-copter (also called Micro Air Vehicle, MAV) or a helicopter, the motion of the camera directly corresponds to the plane movements. For simplification, only a planar landscape model is used nowadays to describe the global motion of the scene. However, if objects like buildings or mountains are close to the camera, i.e. the MAV is at a low altitude, this simplification is not valid. Therefore we propose a more complex model by introducing a 2D mesh-based motion compensation technique, also known as image warping, to compensate the global motion. We show the benefits if used for mosaick creation by smaller artifacts due to perspective distortions and smaller drift problems. We also improve a moving object detection system to identify moving objects more reliably. Moreover, the proposed method is also more robust in case of lens distortions.
Hot water flooding and cold water flooding in heavy oil reservoirs (2016)

Murphy Oil’s Seal asset in the Peace River Oil Sands region in North West Alberta, Canada, has a remarkable capacity for implementation of Enhanced Oil Recovery (EOR) processes. Some wells in Seal have shown strong historical production due to excellent permeability and the foamy solution gas drive mechanism. The reservoir characteristics in this portion are highly variable where determining the most suitable EOR method is very challenging. Two of the potential EOR candidates which have been evaluated for this portion include conventional cold waterflooding and hot waterflooding. Results of EOR core analysis, logging, detailed seismic and petrophysical studies, and history-matched reservoir simulation and forecast indicate that cold waterflooding outperforms hot waterflooding. This is surprising as hot waterflooding is believed to outperform cold waterflooding in most medium heavy oil reservoirs.
High Relative Humidity In‐Package of Fresh‐Cut Fruits and Vegetables: Advantage or Disadvantage Considering Microbiological Problems and Antimicrobial Delivering Systems? (2008)

This hypothesis article states that the high relative humidity (RH) of packaged fresh-cut fruits or vegetables that is associated with spoilage can be used as an advantageous way to deliver antimicrobial compounds using cyclodextrins (CDs) as carriers. CDs can function as antimicrobial delivery systems as they can release antioxidant and antimicrobial compounds (guest molecules) as the humidity levels increase in the headspace. Hydrophobic antimicrobial guests can be complexed with CDs due to the amphiphatic nature of the host. Then, at high RH values, due to the water-CDs interaction, host-guest interactions are weakened; consequently, the antimicrobial molecule is released and should protect the product against the microbial growth. Potential antimicrobial compounds capable of forming complexes with CDs are discussed, as well as possible applications to preserve fresh-cut produce and future research in this area.
THE NUMERICAL STABILITY OF THE IMPROVED (2015)

Abstract. The third order interval Gargantini method for the simultane-ous inclusion of polynomial zeros was improved to the fourth order method by Carstensen and Petkovic ́ [An improvement of Gargantini’s simultaneous inclusion method for polynomial roots by Schroeder’s correction, Appl. Nu-mer. Math. 13 (1994), 453–468]. We investigate the numerical stability of this improved method in the presence of rounding errors. The dependence of the convergence rate of the considered method on the magnitude of rounding errors is studied. 1.
Evaluation of lytic activity of staphylococcal bacteriophage Sb‐1 against freshly isolated clinical pathogens (2011)

In recent decades the increase in antibiotic-resistant bacterial strains has become a serious threat to the treatment of infectious diseases. Drug resistance of Staphylococcus aureus has become a major problem in hospitals of many countries, including developed ones. Today the interest in alternative remedies to antibiotics, including bacteriophage treatment, is gaining new ground. Here, we describe the staphylococcal bacteriophage Sb-1 - a key component of therapeutic phage preparation that was successfully used against staphylococcal infections during many years in the Former Soviet Union. This phage still reveals a high spectrum of lytic activity in vitro against freshly isolated, genetically different clinical samples (including methicillin-resistant S. aureus) obtained from the local hospitals, as well as the clinics from different geographical areas. The sequence analyses of phage genome showed absence of bacterial virulence genes. A case report describes a promising clinical response after phage application in patient with cystic fibrosis and indicates the efficacy of usage of Sb-1 phage against various staphylococcal infections.

최근 경영환경 변화로 윤리경영의 필요성은 날로 높아지고 있다. 그리고 윤리경영은 기업의 이해관계자 호응, 이미지 및 조직성과와 깊은 관계가 있다. 그러나 이들 주요변수들 간에 어떤 관계인지를 실증적으로 규명한 연구는 찾기 어렵다. 따라서 본 연구는 기업의 윤리경영, 이해관계자 호응, 이미지 및 조직성과에 관한 연구모형을 설계하고, 이들 간의 관계를 실증연구 하였다. 그 결과 첫째, 윤리경영은 기업의 이해관계자 호응이나 이미지와 부분적으로 관계가 있었다. 특히 윤리경영을 잘하는 기업일수록 고객만족이나 지역사회인정이 높은 경향을 보였다. 또한, 윤리경영의 구성요소들 중 윤리문화는 고객, 투자자 및 지역사회의 호의적인 반응을 유도하는 경향을 보였다. 이는 기업이미지의 경우에도 유사하여 윤리적인 문화를 지닌 기업일수록 사회적 책임이나 경쟁력 관련 이미지가 높은 경향을 띠었다. 또한 윤리시스템의 경우는 고객이나 지역사회의 호응을 높이는데, 그리고 경쟁력이미지를 제고하는데 도움이 되었다. 반면, 윤리강령의 이해관계자 호응이나 기업이미지에 대한 기여는 상대적으로 낮았다. 둘째, 윤리경영은 조직성과 중 구성원자긍심과 정적인 관계가 있었다. 이는 특히 윤리문화와 윤리방침의 경우에 더욱 뚜렷한 경향을 보였다. 한편, 윤리경영은 조직시민행동과는 부분적으로 약한 관계가 있었다. 셋째, 이해관계자 호응과 이미지는 상호관계가 있었다. 이해관계자 호응 중 특히, 고객만족과 지역사회인정이 기업의 사회적책임이미지나 경쟁력이미지와 밀접한 경향을 보였다. 넷째, 기업의 이미지가 좋고 이해관계자 호응이 높을수록 조직성과가 높은 경향을 보였다. 특히 재무성과보다 구성원자긍심이나 조직시민행동의 경우에 더 뚜렷하였다. 마지막으로, 윤리경영을 조기에 도입한 기업의 재무성과가 높게 나타났다. 또한 윤리전담 부서는 윤리경영을 통한 지역사회호응을 얻어내고 경쟁력이미지를 확보하는데 기여하였다. 그리고 기업의 노조유무에 대해 일부 이해관계자들은 민감한 반응을 보였다. 본 연구에서는 이러한 실증연구 결과들의 이론적, 실무적 시사점들을 논한 후 관련 주제에 관한 향후 연구과제들을 제시하였다.
Fundamental Calibrators For Stellar Evolution Models: New Eclipsing Binaries In Young Clusters Identified By K2 (2016)

Double-lined eclipsing binaries serve as fundamental calibrators for stellar evolution models. Benchmark grade calibrators (with mass and radius uncertainties of ~3%) having component masses below 1 solar mass are rare, particularly at pre-main sequence stages. We present the discovery and characterization of new eclipsing binaries in young stellar clusters, all identified by K2. In the 5-10 Myr old Upper Scorpius region, the nearest OB association, we present the lowest mass stellar eclipsing binary to date, with both components close to the hydrogen burning limit. Also in Upper Scorpius, we present evidence for a hierarchical triple with an eclipsing pair of brown dwarfs, only the second eclipsing brown dwarf pair known to date. In the 110-125 Myr old Pleiades cluster, only one eclipsing binary was known prior to the K2 mission. We present three new Pleiades eclipsing binaries, all with system masses less than 1 solar mass. We use these systems to critically assess stellar evolution models at low masses and young ages. K2 data in hand has also revealed new eclipsing and transiting systems in the moderately older (600-800 Myr) Hyades and Praesepe clusters.

Usage control in cloud systems (2012)

Cloud system peculiarities, such as enormous resources and long-lasting accesses, introduce new security and management challenges. This paper presents an advanced authorization framework based on the Usage Control (UCON) model and the OASIS XACML standard to regulate the usage of Cloud resources. Our framework addresses the issue of long lasting accesses and it is able to interrupt accesses that are in progress when the corresponding access rights do not hold any more. We provide the implementation of our framework and its integration with the OpenNebula toolkit.
Biocompatible SuFEx Click Chemistry: Thionyl Tetrafluoride (SOF<sub>4</sub>)‐Derived Connective Hubs for Bioconjugation to DNA and Proteins (2019)

We report here the development of a suite of biocompatible SuFEx transformations from the SOF<sub>4</sub> -derived iminosulfur oxydifluoride hub in aqueous buffer conditions. These biocompatible SuFEx reactions of iminosulfur oxydifluorides (R-N=SOF<sub>2</sub> ) with primary amines give sulfamides (8 examples, up to 98 %), while the reaction with secondary amines furnish sulfuramidimidoyl fluoride products (8 examples, up to 97 %). Likewise, under mild buffered conditions, phenols react with the iminosulfur oxydifluorides (Ar-N=SOF<sub>2</sub> ) to produce sulfurofluoridoimidates (13 examples, up to 99 %), which can themselves be further modified by nucleophiles. These transformations open the potential for asymmetric and trisubstituted linkages projecting from the sulfur(VI) center, including versatile S-N and S-O connectivity (9 examples, up to 94 %). Finally, the SuFEx bioconjugation of iminosulfur oxydifluorides to amine-tagged single-stranded DNA and to BSA protein demonstrate the potential of SOF<sub>4</sub> -derived SuFEx click chemistry in biological applications.
Spectral Effects of LED Forward Lighting (2005)

Light emitting diode (LED) forward lighting systems soon will become a reality on today's roadways. One aspect of LED sources that will differ significantly from tungsten halogen (TH) or high intensity discharge (HID) lamps is their spectral power distribution (SPD). Lamp SPD can have considerable impacts on a driver's visual performance. Recent studies have shown that headlamp sources that have more energy in the short wavelength region of the visible spectrum provide benefits to the vehicle operator for off-axis target detection. Calculations were performed on a series of LEDs to determine their potential advantage to visual performance. The LEDs chosen for this analysis are in chromaticity bins partially or fully contained within the SAE J578 definition of white. Similar calculations were performed on HID and TH sources for comparison. It was found that most of the LED sources analyzed can theoretically result in increased off-axis visual performance over current headlamp technology. The results of these calculations are compared to field studies of headlamp spectra to determine the magnitude of these effects as potentially seen in practice.
Classification of malware using structured control flow (2010)

Malware is a pervasive problem in distributed computer and network systems. Identification of malware variants provides great benefit in early detection. Control flow has been proposed as a characteristic that can be identified across variants, resulting in flowgraph based malware classification. Static analysis is widely used for the classification but can be ineffective if malware undergoes a code packing transformation to hide its real content. This paper proposes a novel algorithm for constructing a control flow graph signature using the decompilation technique of structuring. Similarity between structured graphs can be quickly determined using string edit distances. To reverse the code packing transformation, a fast application level emulator is proposed. To demonstrate the effectiveness of the automated unpacking and flowgraph based classification, we implement a complete system and evaluate it using synthetic and real malware. The evaluation shows our system is highly effective in terms of accuracy in revealing all the hidden code, execution time for unpacking, and accuracy in classification.
Correlation of proton transverse relaxation rates (<i>R</i><sub>2</sub>) with iron concentrations in postmortem brain tissue from alzheimer's disease patients (2006)

Iron accumulates in the Alzheimer's disease (AD) brain and is directly associated with beta-amyloid pathology. The proton transverse relaxation rate (R(2)) has a strong linear relationship with iron concentrations in healthy brain tissue; however, an independent test of this relationship has not been extended to AD brain tissue. In this study in vitro single spin-echo (SE) measurements were made on tissue samples from four human AD brains using a 4.7T MRI research scanner. R(2) values were calculated for 14 cortical and subcortical gray matter (GM) and white matter (WM) regions. Atomic absorption spectroscopy was used to measure iron concentrations in the corresponding excised brain regions. Significant positive linear correlations were observed between R(2) values and iron concentrations in GM regions assessed across individual tissue samples and data averaged by brain region. With the use of a predictive model for R(2), a threshold iron concentration of 55 microg Fe/g wet tissue was determined above which R(2) appears to be dominated by the affects of iron in AD brain tissue. High-field MRI may therefore be a useful research tool for assessing brain iron changes associated with AD.
Deep Multimodal Clustering for Unsupervised Audiovisual Learning (2019)

The seen birds twitter, the running cars accompany with noise, etc. These naturally audiovisual correspondences provide the possibilities to explore and understand the outside world. However, the mixed multiple objects and sounds make it intractable to perform efficient matching in the unconstrained environment. To settle this problem, we propose to adequately excavate audio and visual components and perform elaborate correspondence learning among them. Concretely, a novel unsupervised audiovisual learning model is proposed, named as Deep Multimodal Clustering (DMC),that synchronously performs sets of clustering with multimodal vectors of convolutional maps in different shared spaces for capturing multiple audiovisual correspondences. And such integrated multimodal clustering network can be effectively trained with max-margin loss in the end-to-end fashion. Amounts of experiments in feature evaluation and audiovisual tasks are performed. The results demonstrate that DMC can learn effective unimodal representation, with which the classifier can even outperform human performance. Further, DMC shows noticeable performance in sound localization, multisource detection, and audiovisual understanding.

CLINICAL CASE STUDY (2000)

Anna sought psychotherapy because of a back problem for which no medical causation has been found. In this condition, her spine is bent laterally (but not frontally) at the waist to the left accompanied by severe pain. Anna’s condition first began at age 22, approximately 2 years after her arrival in the United States. She reported struggling with feelings of hopelessness and abandonment since leaving Korea. Anna had longed to launch a satisfying life after her migration with financial and emotional support from her oldest sister, who had lived in the U.S. for nearly two decades and who was working as a saleswoman. However, Anna soon found out that her sister was having financial and marital problems of her own and was not in a position to help her. Furthermore, this sister was authoritarian and unfeeling towards Anna. For example, Anna was expected to do her sister’s household chores. When Anna developed a severe allergic reaction to the sister’s dog, the sister blamed Anna for her skin sensitivity without helping her obtain treatment or making arrangements to minimize the dog’s contact with the patient. Other members of Anna’s family who immigrated with her similarly felt abused by this sister, and after many fights and conflicts, each member went his/her separate way. Anna felt like an orphan and after a few months of living on her own returned to live with her sister, bracing herself for a difficult life.
Multiprocessor synchronization for concurrent loops (1988)

Execution of concurrent loops on multiprocessor computers often requires synchronizing the processors. Synchronization schemes are surveyed that are suitable for automatic problem decomposition. The model of a shared-memory multiprocessor is used, as is the concurrent-loop paradigm, which is to compile a loop so each processor is assigned a different loop iteration. The discussion covers data dependence, removing synchronization points, random synchronization, pipelining, barrier synchronization, and critical sections.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Theoretical proposal for determining angular momentum compensation in ferrimagnets (2018)

This work demonstrates that the magnetization and angular momentum compensation temperatures (${T}_{\mathrm{MC}}$ and ${T}_{\mathrm{AMC}}$) in ferrimagnets can be unambiguously determined by performing two sets of temperature-dependent current switching, with the symmetry reversals at ${T}_{\mathrm{MC}}$ and ${T}_{\mathrm{AMC}}$, respectively. A theoretical model based on the modified Landau-Lifshitz-Bloch equation is developed to systematically study the spin torque effect under different temperatures, and numerical simulations are performed to corroborate our proposal. Furthermore, we demonstrate that the recently reported linear relation between ${T}_{\mathrm{AMC}}$ and ${T}_{\mathrm{MC}}$ can be explained using the Curie-Weiss theory.
Early administration of surfactant in spontaneous breathing with nCPAP: feasibility and outcome in extremely premature infants (postmenstrual age ≤27 weeks) (2006)

Surfactant administration during nCPAP is feasible. First results indicate that early complications are rare. This warrants a prospective randomized trial.
Novel site-specific one-step bromination of substituted benzenes (1996)

Regiospecific bromination of benzene derivatives has been carried out with Me2SO–HBr; this method gives excellent yields of 2-bromobenzaldehyde and 2-bromonitrobenzene; strong ortho- and para-directing monosubstituted benzenes give para-bromo derivatives; a general discussion of the mechanism of these reactions is given.
