However, outsourcing is an area where it is difficult to be successful without systematic and strategical approach. Therefore, an object of the present study is to build a basis for an enterprise to grow and develop into a going concern through increase in the productivity by reviewing the concept and actual status of introduction of outsourcing for Korean enterprise, and presenting concrete methods of improvement and strategies of promotion.
[Molecular genetics of the human brain]. (1992)

The review discusses the contribution of molecular genetic studies to the understanding of human brain performance and defines three genetic objectives: 1) to reveal structural or functional features of brain genes specific merely to man; 2) to outline the complete spectrum of genes involved in brain activity and their regulation; 3) to search for genes and genetic defects resulting in common mental disorders. The plasticity and great variety of brain functions are shown to be based on the unique diversity of genes actively transcribing in the brain and the molecular mechanisms of various genetic products of the same gene: alternative splicing, "antiparallel" coding, regulation of gene activity by signal DNA sequences. Gene search policies are described for common mental disorders such as schizophrenia, manic-depressive psychosis, Alzheimer's disease. The attempts to map defective genes by "reverse" genetics have proved that there is a genetic heterogeneity of these diseases. The novel directions in the study of the brain molecular genetic apparatus can be examinations of chromosomal behavior in the cells in various brain regions and genome imprinting.
원보 : HPLC-DAD를 이용한 사물탕 중 3종 성분의 동시분석법 확립 (2009)

Samultang is one of traditional medicine composed of Paeonia lactiflora, Angelica gigas, Rehmannia glutinosa and Cnidium officinale. To develop simultaneous determination of paeoniflorin, decursin and 5-HMF in Samultang, a high performance liquid chromatography with diode array detector was used. To separate three marker components, Dionex C 18 column (5 μm, 120 A, 4.6 mm×150 mm) was used with a gradient elution system of water and methanol. UV wavelength of detector set at 230 nm and 280 nm. This method was validated by linearity, precision test and recovery test. Calibration curves of three standard components were showed good linear regression (R2>0.9973). LOD and LOQ ranged from 0.08 μg/ml to 0.38 μg/ml and 0.25 μg/ml to 1.16 μg/ml, respectively. The relative standard deviations (RSDs) of data of the inter-day and intra-day experiments were less than 0.54% and 0.89%, respectively. The measured results of recovery test were varied from 93.36 to 107.79 with RSD values 0.01~1.45%. The established method was applied for separation of bio-conversion Samultang sample and compared with control sample.
2017 Calibre Essay Prize (winner): 'Salt Blood' (2017)

It is quiet and cool and dark blue. At this depth the pressure on my body is double what it is at the surface: my heartbeat has slowed, blood has started to withdraw from my extremities and move into the space my compressed lungs have created. I am ten metres underwater on a breath-hold dive, suspended at the point of neutral buoyancy where the weight of the water above cancels my body's natural flotation. I turn head down, straighten my body, kick gently, and begin to fall with the unimpeded gravitational pull to the heart of the Earth.
Mass Fashion as Threat in Context and Concept (1991)

During the latter part of the 18th century in Scotland, especially in rural areas, there was a dramatic shift from relatively stable and unchanging dress forms to fashion in dress, the ongoing substitution of existing forms with new ones. From an analysis of primary sources it is clear that these changes were often perceived as threatening. This paper addresses the conceptual relevance offashion as threat, it explores fashion as an ideal symbolic medium for venting perceptions of threat posed by other domains in the social/cultural system, and it addresses the symbolic power of dress and fashion in conserving the perception of social order and stability at the same time that it facilitates cultural change.
4. Characteristics of cellulose acetates 4.1 Characterization and physical properties of cellulose acetates (2004)

Abstract An overview is provided of the basic features of cellulose acetate of various degree of substitution in the solid and liquid crystalline state as well as in solution. These features represent a necessity for an understanding of the properties of these cellulose derivatives and further for mixed esters, which are not presented in this paper. Specifically, the crystal structure of cellulose triacetate will be addressed as well as structures in dilute and semi‐dilute solutions. Thermal, viscoelastic and further properties in the solid state are discussed as well as flow behavior of solutions and their application in molecular weight determination, including false viscosity of commercial 2.5 cellulose acetates.
Influence functions of the Spearman and Kendall correlation measures (2010)

Nonparametric correlation estimators as the Kendall and Spearman correlation are widely used in the applied sciences. They are often said to be robust, in the sense of being resistant to outlying observations. In this paper we formally study their robustness by means of their influence functions and gross-error sensitivities. Since robustness of an estimator often comes at the price of an increased variance, we also compute statistical efficiencies at the normal model. We conclude that both the Spearman and Kendall correlation estimators combine a bounded and smooth influence function with a high efficiency. In a simulation experiment we compare these nonparametric estimators with correlations based on a robust covariance matrix estimator.
Clinical spectrum of levodopa‐induced complications (2014)

The first years of Parkinson disease (PD) treatment are marked by good and sustained responses to dopaminergic therapy. With disease progression and longer exposure to levodopa (l-dopa), patients develop a range of l-dopa-induced complications that include motor and non-motor symptoms. Motor complications include motor fluctuations, characterized by periods of reduced benefit from the medication, and l-dopa-induced dyskinesia, characterized by emergence of hyperkinetic involuntary movements. Dyskinesia can occur at peak effect of l-dopa, at the beginning and end of dose, or between doses. These motor complications are often associated with fluctuations in non-motor symptoms, particularly fluctuations in neuropsychiatric, autonomic, and sensory symptoms. Recognizing such complications and understanding their relationship with the timing of l-dopa doses is essential for adequate diagnosis and management. Society.
On strong irregularities of the distribution of {nα} sequences (1983)

Let U={u n be a sequence in [0, 1] k and $$\Delta _N^U = \mathop {\sup }\limits_l |\Delta _N (I)| = \mathop {\sup }\limits_l \left| {\sum\limits_{\mathop {u_n \in l}\limits_{1 \leqq n \leqq N} } {1 - N|l|} } \right|$$ (l a subinterval of [0, 1] k ). By Schmidt’s theorem Δ N > c 1 log N for any N if k = 2 while for k = 1 only $$\overline {\lim } \frac{{\Delta _N }} {{\log N}} > c_2 > 0$$ holds and we have sequences (e.g. {n α} sequences) for which Δ N ≦1 for infinitely many N. Inspite of this fact we have the following Theorem: Let u n = {nα}. With a suitable δ∈(0, 1) and for every N>N 0 $$\Delta _n > c_3 \log N$$ holds for all but at most N δ values of n, 1≦n≦N. (Here c 3>0 is an absolute constant.
Gene therapy for mucopolysaccharidosis (2007)

Mucopolysaccharidoses (MPS) are due to deficiencies in activities of lysosomal enzymes that degrade glycosaminoglycans. Some attempts at gene therapy for MPS in animal models have involved intravenous injection of vectors derived from an adeno-associated virus (AAV), adenovirus, retrovirus or a plasmid, which primarily results in expression in liver and secretion of the relevant enzyme into blood. Most vectors can correct disease in liver and spleen, although correction in other organs including the brain requires high enzyme activity in the blood. Alternative approaches are to transduce hematopoietic stem cells, or to inject a vector locally into difficult-to-reach sites such as the brain. Gene therapy holds great promise for providing a long-lasting therapeutic effect for MPS if safety issues can be resolved.

The effect of lactulose, pectin, arabinogalactan and cellulose on the production of organic acids and metabolism of ammonia by intestinal bacteria in a faecal incubation system (1990)

An in vitro faecal incubation system was used to study the metabolism of complex carbohydrates by intestinal bacteria. Homogenates of human faeces were incubated anaerobically with added lactulose, pectin, the hemicellulose arabinogalactan, and cellulose, both before and after subjects had been pre-fed each carbohydrate. Fermentation of added substrate was assessed by the production of short-chain fatty acids (SCFA) and suppression of net ammonia generation over 48 h of incubation. Control faecal homogenates to which carbohydrate was not added yielded an average increment of SCFA of 43 mmol/l, equivalent to 172 mmol/kg in the original stool. The addition of lactulose, pectin and arabinogalactan each increased the yield of SCFA by a similar amount, averaging 6.5 mmol/g carbohydrate or 1.05 mol/mol hexose equivalent; organic acid yield was not increased by pre-feeding these substances for up to 2 weeks. Acetate was the major SCFA in all samples at all times and, after pre-feeding with extra carbohydrate, butyrate concentrations exceeded propionate in all samples. Faecal homogenates incubated with cellulose showed no greater SCFA production than controls over the first 48 h, but there was a slight increase when samples from two subjects pre-fed cellulose were incubated for 14 d. Net ammonia generation was markedly suppressed by addition of lactulose to faecal incubates with an initial period of net bacterial uptake of ammonia. Pectin and arabinogalactan also decreased ammonia generation, but the reductions were not significant unless subjects were pre-fed these materials; cellulose had no effect on ammonia generation.

Dolphin skin as a natural anisotropic compliant wall (2006)

Although the success of compliant walls in mimicking dolphin skin is well known, the drag-reducing properties of a dolphin's skin are still unclear. Moreover, little is known about the relation between the 3D structure of the skin and the local flow conditions. To study the role of a dolphin's skin in reducing the drag the skin morphology parameters were compared with the parameters of an anisotropic compliant wall and a possible flow-skin interface was considered. The 3D structure of skin from different locations was modelled using serial histological sections of the skin. The hydrodynamics of the dorsal fin of the harbour porpoise was studied by means of computer simulation of the flow around virtual models of the fin. It was found that the distribution of the skin morphology parameters is correlated with the local flow parameters on the fin surface. The skin structure appears to allow the flow-skin interface to behave similar to an anisotropic compliant wall in the regions of favourable and adverse pressure gradients on the fin. The relation founded between the skin morphology and the local flow parameters could be useful in the design of multipanel anisotropic compliant walls.
Surface passivation of Cu(In,Ga)Se2 using atomic layer deposited Al2O3 (2012)

With Al2O3 passivation on the surface of Cu(In,Ga)Se2, the integrated photoluminescence intensity can achieve two orders of magnitude enhancement due to the reduction of surface recombination velocity. The photoluminescence intensity increases with increasing Al2O3 thickness from 5 nm to 50 nm. The capacitance-voltage measurement indicates negative fixed charges in the film. Based on the first principles calculations, the deposition of Al2O3 can only reduce about 35% of interface defect density as compared to the unpassivated Cu(In,Ga)Se2. Therefore, the passivation effect is mainly caused by field effect where the surface carrier concentration is reduced by Coulomb repulsion.
School Rituals and Educational Practice (2002)

This study on school rituals, based on an socio-anthropology view, has arisen from the hypothesis of the anthropologist Roberto Da Matta. This hypothesis supports the theory that rituals are useful, particularly in a complex society, to promote its social identity and develop its character. Da Matta observes that it is as if the ritual domain were a privileged area from whence to enter the cultural kernel of a society, its main ideology, its system of values. This is the reason why we have put forward the proposal that to enquire about rituals at schools can result in a useful contribution to the analysis of this institution in its reproductive dimension or in the construction of a determined social structure. This research was carried out in three schools in the city of Posadas, Misiones, Argentina. In two of them, the research was pursued as a sustained, long-term and ethnographic observation: students, parents, teachers and the managing staff were interviewed. In the third school, just the teachers and the managing staff were interviewed by means of a probing survey; in both cases, strategies, sources and techniques were combined.
Calcium dicarboxylates nucleation of β‐polypropylene (2002)

Abstract Seven dicarboxylates of calcium were synthesized. The effect of dicarboxylate on the formation of β‐form polypropylene was investigated by X‐ray diffraction. Calcium pimelate, calcium suberate, calcium phthalate, and calcium terephthalate have been found to be an effective β‐nucleator. The K x values of the isotatic propylene samples with 0.5 wt % of the nucleators above are 0.95, 0.96, 0.93, and 0.62, respectively. Calcium succinate, calcium adipate, and calcium sebacate behave invalidly on the nucleating of the β‐phase. We conducted an investigation on the affect of particle shape, crystal form, and crystallinity upon the level of the β‐form. The X‐ray diffraction of the effective nucleators reveals a common character that their first reflection locate at the d‐spacing between 10 to 13 Å, indicating structural similarity of the nucleators with β‐polypropylene. The nucleation mechanism is explained by the cooperative effect of the nonpolar and polar part of nucleating agents in the crystallization of polypropylene. © 2002 Wiley Periodicals, Inc.

A Local, High-Density, Single-Nucleotide Polymorphism Map Used to Clone Caenorhabditis elegans cdf-1 (1999)

Ras-mediated signaling is required for induction of vulval cell fates during Caenorhabditis elegans development. By screening for suppressors of the multivulva phenotype caused by constitutively active let-60 ras, we identified the mutation n2527. To clone the gene affected by n2527, we developed a method for high-resolution mapping. We took advantage of the genomic DNA sequence of the N2 strain by using DNA sequencing to scan for single-nucleotide polymorphisms (SNPs) at defined genomic positions of the RC301 strain. An average of one polymorphism per 1.4 kb was detected in predicted intergenic regions. Because of this high frequency, DNA sequencing is an efficient method to scan for SNPs. By alternating between identifying SNPs and mapping n2527 using selected recombinants, we generated an SNP map of progressively higher density. An intensive search for SNPs resulted in a local map with an average marker spacing of approximately 4 kb. This was used to map n2527 to a 9.6-kb interval. The small size of this interval made it feasible to use DNA sequencing to identify the molecular lesion. In principle, this approach can be used for high-resolution mapping of any C. elegans mutation. Furthermore, this approach can be applied to other species as the genomic sequence becomes available. The n2527 mutation affects a previously uncharacterized gene that we named cdf-1, as it encodes a predicted protein with significant similarity to members of the cation diffusion facilitator family.
Enhancement of 5-Hydroxytryptamine 3A Receptor Function by Phorbol 12-Myristate, 13-Acetate is Mediated by Protein Kinase C and Tyrosine Kinase Activity (2002)

The effects of phorbol 12-myristate, 13-acetate (PMA) on 5-hydroxytryptamine (5-HT)-evoked ion currents in the mouse 5-HT3A receptor were examined. Perfusion with PMA caused a concentration dependent potentiation of 5-HT mediated currents and increased both potency and efficacy of 5-HT at the 5-HT3A receptor expressed in Xenopus oocytes. Enhancement of receptor function was partially blocked by injection of oocytes with PKCI, the peptide inhibitor of protein kinase C (PKC). Mutation of all 12 intracellular serine and threonine residues to alanine was without effect on PMA-induced potentiation of 5-HT elicited currents. Mutation of tyrosine 458 in the 5-HT3A receptor lacking intracellular serines and threonines reduced the PMA-induced potentiation of 5-HT evoked currents by approximately 55%. In contrast, mutation of tyrosine 458 in the wild-type receptor did not alter PMA-induced enhancement. The tyrosine kinase inhibitor, lavendustin A, reduced the enhancement of 5-HT3A receptor mediated currents by PMA in the mutant 5-HTA3A receptor containing no intracellular serine or threonine residues, but not in the wild-type receptor. Thus, the role of intracellular serines and threonines is redundant with that of tyrosine, suggesting that these two components act through a similar pathway in response to PMA treatment.
SIMULTANEOUS ASSESSMENT OF CHANGES OCCURRING DURING BATCH FERMENTATION (1966)

Detailed study of the fermentation of wort by Saccheromyces cerevisiae on a pilot scale showed that all the oxygen and considerable quantities of certain amino acids present in the wort were absorbed by the yeast before active fermentation commenced. The pH fell rapidly after pitching and reached a constant level after 32 hr. The α acids and iso α acids in the wort diminished in parallel with the decrease in pH and the increase in concentration of suspended yeast, respectively. Esters and higher alcohols appeared as the carbohydrate content of the wort diminished. Their production did not parallel the uptake of amino acids or changes in the amount of suspended yeast. The level of diacetyl reached a maximum when valine was fully taken up from the wort. Distillation of fermenting wort caused production of diacetyl.
Concept Representation and Its Role in Artifact Development (2015)

In this progress report of our System Comprehension research, we present how one of our requirements is fulfilled. The requirement is translating one Artifact Type to other, with less depend on its type. For example we need two diagram type from a C Language source code. The source code is translated to a Sequence Diagram, and then the source code translated to other. When translating the source code into other diagram, we may reuse several part of previous translation solution (source code to sequence diagram). It reduces recurrent activities. One of its reusable component is called Concept Representation. In this paper we present two types of Concept Representation. It may use several Level of Abstraction instances, instead of use a certain Level of Abstraction. It is more sophisticated, more complex to implement in a digital system.
Optimal Power Flow based Congestion Management Methods for Competitive Electricity Markets (2010)

Congestion management is one of the major tasks performed by system operators to ensure the operation of transmission system within operating limits. In the emerging electric power market, the congestion management becomes extremely important and it can impose a barrier to the electricity trading. In the present paper, a concept of transmission congestion penalty factors is developed and implemented to control power overflows in transmission lines for congestion management. Three methods based on optimal power flow are proposed to alleviate congestion in transmission lines and tested. The first two methods require re-dispatching of generators and changes in capacitors' reactive support only. They can be differentiated on the basis of economic cost involved in making required changes to above variables. The third method deals with load curtailment scheme based on willing to pay charges paid for different transactions in the system to avoid congestion. The formation of different categories for charging willing to pay charges from pool consumers is new feature of this scheme.
Wettability switching between high hydrophilicity at low pH and high hydrophobicity at high pH on surface based on pH-responsive polymer (2008)

Surfaces obtained by modifying poly(N,N'-dimethylaminoethyl methacrylate) (PDMAEMA) on rough silicon substrates are highly hydrophilic at low pH and highly hydrophobic at high pH; such surfaces effectively supplement the research on the wettability of solid surfaces based on the pH-responsive polymers.
