최근 기업의 비즈니스 프로세스를 혁신하고 효율화하기 위한 다양한 연구가 활발히 진행되고 있는 가운데, 의미 있는 비즈니스 프로세스 모델을 생성하고 분석하는 프로세스 마이닝 연구 분야가 주목받고 있다. ERP (Enterprise Resource Planning) 시스템이나 BPM (Business Process Management) 시스템에서 발생되는 업무 처리 내역이나 이벤트 로그를 분석하여 의미 있는 정보나 규칙을 발견해 낼 수 있는 프로세스 마이닝 기법은 다양한 분야에서 적용되고 있다. 본 연구에서는 프로세스 마이닝 도구인 ProM 시스템을 실제 고장 수리 사례에 적용하여 고장 수리 프로세스를 분석하고 제품의 주요 고장 패턴을 발견하는 방법을 제시한다. 고장 수리 프로세스 분석 결과 단순 통계 분석 결과에서 발견할 수 없었던 연결된 흐름의 빈도 분석이 가능하였으며, 연결된 흐름들 중에서 문제가 되는 프로세스에 대한 업무 향상 방안을 제시할 수 있었다. Recently, studies about process mining for creating and analyzing business process models from log data have received much attention from BPM (Business Process Management) researchers. Process mining is a kind of method that extracts meaningful information and hidden rules from the event log of enterprise information systems such as ERP and BPM. In this paper, repair processes of electronic devices are analyzed using ProM which is a process mining tool. And based on the analysis of repair processes, the method for finding major failure patterns is proposed by multi-dimensional data analysis beyond simple statistics. By using the proposed method, the reliability of electronic device can be increased by providing the identified failure patterns to design team.

Insights into the neurochemical signature of the Innervation of Beige Fat (2018)

These data indicate that, coincident with beiging, there is a shift toward a "brown-like" neurochemical signature of postganglionic neurons projecting to inguinal white fat, an increased expression of POMC, and, consistent with a causative role for this prohormone in beiging, an αMSH-mediated increase in beige gene markers in isolated adipocytes.

Role of Mitochondria in Ischemic Acute Renal Failure (1983)

Ischemic ARF is characterized by progressive mitochondrial accumulation of Ca++ which is inversely correlated with the level of oxidative phosphorylation. At least two possibilities exist which would be compatible with these data 1) depressed respiration leads to Ca++ accumulation or 2) increased mitochondrial Ca++ leads to reduced mitochondrial respiration. We favor the latter hypothesis for the reasons outlined above; furthermore, this conclusion is supported by the observations of Lehninger, made some 20 years ago: first, that either oxidative phosphorylation or mitochondrial Ca++ accumulation can be accomplished by intact mitochondria but that these events cannot occur simultaneously and second, that Ca++ accumulation takes precedence over oxidative phosphorylation. Our observation made during post-ischemic reflow that mitochondrial Ca++ accumulation occurs to a significant degree, strongly suggest a potential role for mitochondrial Ca++ overload in the pathogenesis of ARF. Nevertheless, this is not an irreversible pathogenetic process. Clearly, impermeant solutes, vasodilators and Ca++ membrane blockers will alter the natural history of this injury and prevent the severity of the functional defect. A common mechanism of action may involve direct or indirect modification of cellular Ca++ overload in renal vascular and epithelial tissue. The vascular smooth muscle may then revert to a less constricted state with a subsequent more rapid recovery of renal blood flow and that the renal epithelial cell death may be minimized thereby reducing tubular obstruction.

Neural Stem Cells (2006)

Abstract Neural stem cells (NSCs) may teach us about how cell fate choices are made and which genes regulate these choices. In addition, NSCs might be a source of tissue for cell therapy. Studies focusing on the mechanisms of NSC growth and differentiation suggest they may be more plastic than had been anticipated.
A mass spectrometric study of 1,4‐dioxa‐8‐azaspiro[4.5]decane (1982)

Abstract The mass spectrum of 1,4‐dioxa‐8‐azaspiro[4.5]decane (4‐ethylenedioxypiperidine) showed a prominent peak at m/e 87. Ethylenedioxy ketals commonly give a fragment of m/e 86 and other fragments of higher mass than 87. A mechanism for formation of a m/e 87 fragment was formulated and evidence for this mechanism and the structure of the fragment was obtained by deuterium labelling. Structures and mechanisms of formation of other major fragments were also studied.

<title>Useful nonlinear effects in optical microcavities and their applications</title> (2007)

Nowadays, all optical devices based on nonlinear effects acquire a great importance in optical communications systems and photonic processing. Particularly relevant are the devices that use low-level power pumping in the generation of those effects. These optical devices can be implemented by means of different structures and materials. One of the most significant structure, here described and presented, is the semiconductor semimagnetic microcavity, composed by a Fabry-Perot microcavity with a semiconductor semimagnetic material and a quantum well in the middle. Inside these media nonlinear effects such as four wave mixing and magneto-optical polarisation rotations can be observed and utilised for developing optical amplifiers, wavelength converters and nonlinear magneto-optical based devices. In order to reduce the pumping power needed for obtaining nonlinear effects new structures with different materials can be built. For instance, Fabry-Perot vertical microcavities, whispering gallery based microcavities or hybrid system of photonic crystal microcavities can improve their performance and so make possible a real implementation. A key point in the design of such micro-resonators is the election of the appropriate material inside. A study of the influence of several materials, with a high dispersion and able to provoke electromagnetically induced transparency is, also, presented. The changes of the quality factor of these nonlinear micro-resonators are analysed. Potential applications for optical computing are shown.
Presence and activity of compounds with GnRH-like activity in the ovary of seabream Sparus aurata (1997)

The binding and activity of gonadotropin-releasing hormone (GnRH) were characterized in the mature gilthead seabream (Sparus aurata) ovary by use of an analogue of salmon GnRH([D-Arg6,Trp7,Leu8,Pro9-N(Et)]GnRH, sGnRH-A) as labeled ligand. The binding of 125I-sGnRH-A to the seabream ovarian membrane preparation was saturable, displaceable, reversible, and dependent on time, temperature and tissue concentration. Addition of unlabeled s-GnRH-A displaced the radio-ligand in a dose-related manner, indicating the presence of one class of high-affinity binding sites with an equilibrium dissociation constant of 45.5 +/- 6.2 nM. Addition of other GnRH peptides, including salmon GnRH ([Trp7,Leu8]GnRH) and chicken GnRH-II ([His5,Trp7,Tyr8]GnRH), also displaced 125I-sGnRH-A; all these peptides bound with lower affinities than sGnRH-A to the seabream ovarian binding site. In this study, we also demonstrated the presence of compounds with GnRH-like activity in the ovary of seabream. Seabream ovarian extract stimulated pituitary gonadotropin release from the goldfish pituitary and displaced 125I-sGnRH-A binding in the seabream ovary. Furthermore, addition of sGnRH-A to cultured seabream oocytes directly stimulated reinitiation of oocyte meiosis, as indicated by germinal vesicle breakdown. Overall, the present study characterizes GnRH-binding sites in the seabream ovary and supports the hypothesis that GnRH or compounds with GnRH-like activity play an autocrine/paracrine role in the regulation of ovarian function in the seabream ovary.
Harmonic cancellation by mixing nonlinear single-phase and three-phase loads (2000)

The voltage on the distribution line is, in most cases, distorted even at no load of the transformer. This is due to the "background" distortion on the medium-voltage line caused by the large number of single-phase nonlinear loads, such as PCs, TVs, VCRs, etc. This paper proposes a method to mix single-phase and three-phase nonlinear loads and reduce the harmonic currents significantly. The dependence of the phase angle of the harmonic currents as a function of the short-circuit impedance is investigated using SABER for the three-phase and the single-phase diode rectifier both with and without DC-link inductance. The phase angle of the fifth harmonic current of a three-phase diode rectifier is always in counterphase with the fifth harmonic current of a single-phase diode rectifier. This leads to the conclusion that adding three-phase rectifier load can actually improve the power quality at the transformer. This is also validated by a number of on-site measurements in several applications of three-phase adjustable-speed drives.
Proteasome-Dependent Regulation of p21WAF1/CIP1Expression (1996)

Proteasome-dependent degradation of regulatory proteins is a known mechanism of cell cycle control. We found that the proteasome-specific inhibitor lactacystin (LC) induced expression of the cell cycle inhibitor p21WAF1/CIP1 in human cancer cells regardless of their p53 status. Both wild-type (wt) p53 and p21 protein levels increased by two hours in wt p53 containing cells, whereas mutant (mt) p53 levels decreased and the increase in p21 levels was delayed to 6 hr following inhibition of proteolysis by LC in mt p53 expressing cells. We found that wt but not mt p53 expressing cells increased p21 mRNA and p21-promoter reporter levels following LC exposure, suggesting transcriptional induction of p21. Inhibition of protein synthesis by cycloheximide demonstrated increased p21 protein half-life in the presence of LC in mutant p53 containing cells. p21 induction was correlated with the cytostatic effects of LC. The results suggest that p21 protein expression could be increased by transcriptional mechanisms as well as inhibition of proteolysis by LC.
SUBSTRUCTURE PSEUDO DYNAMIC TEST OF EXISTING RC BUILDINGS WITH SOFT STORY INCORPORATING RESPONSE CONTROL ELEMENTS (2005)

This paper proposes a new technique for structural control of RC buildings with soft story by using ductile short columns as response control devices placed beside the existing columns at the soft story. The objective of the response control is upgrading safety as well as reparability for damage mitigation without partitioning off the spaces at the soft story. This device is made by High Performance Fiber Reinforced Cementitious Composite (HPFRCC), which exhibits multiple cracking and strain-hardening characteristics in the uni-axial tensile stress. It has been found that the HPFRCC device shows a very good ductile structural manner in conjunction with a high resistance capacity against the axial force. The main role of these devices are to increase story shear capacity to reduce response drift of the soft story, and to support axial force due to overturning moment in order to reduce axial force acting on the soft story columns. A substructure pseudo-dynamic test were conducted in order to investigate the advantages by using HPFRCC devices, and to confirm the seismic response analyses. As the result of the experiment, the seismic response of the RC buildings with soft story was successfully controlled by using HPFRCC device, and the reliability of the analytical tool has also been clarified.

Modeling the Resting State of Oxalate Oxidase and Oxalate Decarboxylase Enzymes (2008)

In view of the biological and commercial interest in models for Oxalate Decarboxylases (OxDC) and Oxalate Oxidases (OxOx), we have synthesized and characterized three new Mn (II) complexes ( 1- 3) employing N3O-donor amino-carboxylate ligands (TCMA, 1,4,7-triazacyclononane- N-acetic acid; K (i) Pr 2TCMA, potassium 1,4-diisopropyl-1,4,7-triazacyclononane- N-acetate; and KBPZG, potassium N,N-bis(3,5-dimethylpyrazolyl methyl)glycinate). These complexes were characterized by several techniques including X-ray crystallographic analysis, X-band electron paramagnetic resonance (EPR), electrospray ionization mass spectrometry (ESI-MS), and cyclic voltammetry. The crystal structures of 1 and 3 revealed that both form infinite polymeric chains of Mn (II) complexes linked by the pendant carboxylate arms of the TCMA (-) and the BPZG (-) ligands in a syn-antipattern. Complex 2 crystallizes as a mononuclear Mn (II) cation, six-coordinate in a distorted octahedral geometry. Although complexes 1 and 3 crystallize as polymeric chains, all compounds present the same N3O-donor set atoms around the metal center as observed in the crystallographically characterized OxDC and OxOx. Moreover, complex 2 also contains two water molecules coordinated to the Mn center as observed in the active site of OxDC and OxOx. ESI-MS spectrometry, combined with EPR, were useful techniques to establish that complexes 1- 3 are present as mononuclear Mn (II) species in solution. Finally, complexes 1- 3 are able to model the resting state active sites, with special attention focused on complex 2 which provides the first exact first coordination sphere ligand structural model for the resting states of both OxDC and OxOx.
A novel cyclic AMP response element-binding protein-1 (CREB-1) splice product may down-regulate CREB-1 activity (1995)

In this report we identify novel spliced forms of cyclic AMP (cAMP) response element-binding protein-1 (CREB-1) mRNA. These forms contained an additional 17 nucleotide insert, which we refer to as the beta exon, located between exons 4 and 7 of the delta, and 5 and 7 of the alpha forms of CREB-1 transcript (nomenclature of Ruppert et al. 1992; EMBO Journal 11, 1503-1512). The inclusion of the beta exon led to the generation of mRNAs in which the frame of CREB-1 sequences 3' to the exon was shifted such that the encoded proteins terminate after the transactivation domain, but before the target serine for cAMP-dependent protein kinase. The beta exon-containing CREB-1 mRNAs were more abundant in tissues that respond poorly to cAMP, suggesting that the generation of beta CREB-1 mRNAs may contribute to the down-regulation of CREB-1 activity and cAMP responsiveness.
Exploiting Mechanical Flexure as a Means of Tuning the Responses of Large-Scale Periodic Structures (2015)

We present techniques for designing large-scale, mechanically tunable periodic structures (PSs). Overlapping combined with relative movement, stretching/compression, and flexure are the three mechanical tuning techniques studied in this paper. We demonstrate that all of these mechanical movements may be used to tune the capacitance and inductance of elementary periodic structures with capacitive and inductive surface impedances over wide ranges of values. Analytic formulas for calculating the variable inductance and capacitance of these tunable PSs are also provided. These elementary PSs are the building blocks of a wide range of other PSs with more complicated unit cells and response types. One such structure-a frequency selective surface (FSS) composed of series combination of these inductive and capacitive structures-is also examined to demonstrate the application of the proposed tuning and analysis concepts. The FSS is fabricated on an accordion-like substrate that can be contracted or stretched to change its frequency of operation. The response and tuning properties of this structure are experimentally characterized using a free-space measurement system. A very good agreement between theory and experiment is obtained. This demonstrates that the behavior of such complex mechanically tunable PSs can be analyzed by examining the behavior of their constitutive inductive and capacitive elements.
Diagnosing high-porosity sandstones; strength and permeability from porosity and velocity (1999)

Abstract Nonuniqueness in relating velocity to porosity in core and well-log data complicates interpretation of sonic and seismic measurements. One reason for this nonuniqueness in sandstones is clay (e.g., Han, 1986). Another reason is textural variability among samples. Dvorkin and Nur (1996) examine two relatively clay-free sandstone groups in the same porosity range, but whose velocities significantly differed (Figure 1a). By comparing the data with effective-medium theories, they interpret this velocity difference as resulting from the difference in the position of diagenetic cement. The explanation is that in the "fast" (Oseberg) rocks (contact) cement is located predominantly at the grain contacts, whereas in the "slow" (Troll) rocks (noncontact) cement is located predominantly away from these contacts.
Heterocyclic syntheses with malonyl chloride. Part IX. 2-Substituted 4-chloro-6-pyrimidones from certain nitriles (1968)

Chloroacetonitrile with malonyl chloride yielded 2,3-dichloro-4,6-dihydroxypyridine together with an unexpected product, 4-chloro-2-chloromethyl-6-pyrimidone. Further examples of this new synthesis of 2-substituted 4-chloro-6-pyrimidones were obtained with fluoro- and bromo-acetonitrile, α-bromopropionitrile, and acetonitrile. Propio- and butyro-nitrile each gave a mixture of pyridine and pyrimidine product, whilst various other nitriles gave only the pyridine products. The expected fully substituted pyrimidone was obtained from fluoroacetonitrile and chloromalonyl chloride, and from dibromoacetonitrile with bromomalonyl chloride. Some novel halogen-transfer reactions were encountered in other cases.

Effective jump-pointer prefetching for linked data structures (2003)

Current techniques for prefetching linked data structures (LDS) exploit the work available in one loop iteration or recursive call to overlap pointer chasing latency. Jump-pointers, which provide direct access to non-adjacent nodes, can be used for prefetching when loop and recursive procedure bodies are small and do not have sufficient work to overlap a long latency. This paper describes a framework for jump-pointer prefetching (JPP) that supports four prefetching idioms: queue, full, chain, and root jumping and three implementations: software-only, hardware-only, and a cooperative software/hardware technique. On a suite of pointer intensive programs, jump-pointer prefetching reduces memory stall time by 72% for software, 83% for cooperative and 55% for hardware, producing speedups of 15%, 20% and 22% respectively.
Synthesis of Binuclear Ligands Possessing Two Discrete Multidentate N-Heterocyclic Podand Coordination Sites and Their Bimetallic Nickel(II) Complexes (2001)

Abstract Binuclear ligands possessing two discrete multidentate N-heterocyclic podand coordination sites connected by a flexible propylene spacer and a rigid m-xylene spacer were synthesized. Treatment of the binuclear ligands with Ni(Oac)2 afforded the bimetallic nickel(II) complexes with two discrete nickel centers. The single-crystal X-ray structure determination of the bimetallic nickel(II) complex with a propylene spacer revealed a little distorted square planar geometry at each nickel center.
