음료 패키지디자인에 적용된 컬러의 기능에 관한 연구 -2013년 국내 출시 글라소 비타민워터를 중심으로- (2013)

소비자가 구매에 미치는 영향중 시각이 87%를 차지한다. 그 중 컬러는 상품에 있어서의 가장 중요한 요소이다. 본 연구는 ㈜코카콜라의 음료 브랜드인 글라소 비타민워터의 패키지디자인에서 표현된 10가지 제품 컬러의 기능을 통해 적합성을 연구해 보았다. 컬러의 기능은 심리 기능, 심미 기능, 상징 기능, 식별 기능, 안전 기능, 소통 기능의 6가지 나눌 수 있다. ``영양성분``이 들어간 물이라는 개념의 글라소 비타민워터의 2013년도 대한민국에서 출시된 제품을 연구대상으로 삼았다. 그 결과 ‘멀티브이’가 39.4%로 컬러의 기능을 잘 반영하였다. ‘멀티브이’는 흰색 반투명한 물의 컬러가 순수하고 깨끗하고 순수성으로 표현됐고, 영양성분에 대한 기대감에 옥색이 치유의 컬러로 가장 많이 선택 되었다. 반면 ‘플래시’ 2.1%, ‘리스토어’2.4%, ‘포커스’3.5%가 가장 낮게 조사, 컬러의 부적합 여부도 ‘트리플엑스’와 ‘리스토어’가 18%로 조사되었다. 레드 계열은 사람들의 무의식 속에 음료로서는 포함하지 말아야 할 위험, 흥분, 분노의 이미지를 잠재의식 속에 있기 때문에 낮은 평가를 받았다. 또한 92%가 시음 경험이 있었음에도 68%가 코카콜라 브랜드임을 모르고 있었다. 코카콜라의 블랙 이미지가 물의 순수함을 표현하기에 한계를 갖고 있었기 때문에 글라소 비타민워터만의 우회적인 전략적인 접근으로 보인다. 패키지디자인에 있어 전략적으로 컬러를 수용하되 컬러의 기능을 소비자 입장에서 반영해야 팔리는 디자인을 만들어 낼 수 있다.
Performing PSK demodulation using six-ports (1994)

A six-port junction is used to perform demodulation of PSK signals directly at RF frequencies. The proposed direct phase demodulator is capable of demodulating various digital modulations such as BPSK, QPSK, etc. The hardware imperfections are readily eliminated by software. Due to the absence of the frequency conversion stages the receiver becomes very simple. Measurements have been performed at mm-wave frequencies (40GHz) on DBPSK demodulation. The results outline a promising new direct digital receiver.
Supervised Machine Learning Methods Applied to Predict Ligand- Binding Affinity (2017)

Experimental biophysical techniques were able to determine the structures of over 120,000 macromolecules. Considering also the evolution of binding affinity information, we may say that we have a promising scenario for development of scoring functions, making use of machine learning techniques. Recent developments in this area indicate that building scoring functions targeted to the biological systems of interest shows superior predictive performance, when compared with other approaches.
Correction: Functional Analysis of the ComK Protein of Bacillus coagulans (2013)

The genes for DNA uptake and recombination in Bacilli are commonly regulated by the transcriptional factor ComK. We have identified a ComK homologue in Bacillus coagulans, an industrial relevant organism that is recalcitrant for transformation. Introduction of B. coagulans comK gene under its own promoter region into Bacillus subtilis comK strain results in low transcriptional induction of the late competence gene comGA, but lacking bistable expression. The promoter regions of B. coagulans comK and the comGA genes are recognized in B. subtilis and expression from these promoters is activated by B. subtilis ComK. Purified ComK protein of B. coagulans showed DNA-binding ability in gel retardation assays with B. subtilis-and B. coagulans-derived probes. These experiments suggest that the function of B. coagulans ComK is similar to that of ComK of B. subtilis. When its own comK is overexpressed in B. coagulans the comGA gene expression increases 40-fold, while the expression of another late competence gene, comC is not elevated and no reproducible DNAuptake could be observed under these conditions. Our results demonstrate that B. coagulans ComK can recognize several B. subtilis comK-responsive elements, and vice versa, but indicate that the activation of the transcription of complete sets of genes coding for a putative DNA uptake apparatus in B. coagulans might differ from that of B. subtilis.
Need for Immunization Against Hepatotropic Viruses in Children With Chronic Liver Disease (2014)

A total of 90.8%, 39.1%, and 19.7% of children with CLD from the developing world are exposed to hepatitis A, B, and E infections, respectively. Selective hepatitis A vaccination (patients younger than 5 years of age) and universal hepatitis B vaccination are required to protect children with CLD. Sanitation improvement and HEV vaccine trial are needed for prevention against HEV.
Different Types of Nanosized Carbon Materials Produced by a Metal Dusting Process (2008)

Preparation of carbon nanorods, multiwall nanotubes, single-wall nanotubes, and nanoballs, depending on reaction conditions, is demonstrated by a metal dusting process, in which a blasted 304 L stainless steel coupon and CO−CO2 mixed gas are reacted in the 500−800 °C temperature range. During the process, fresh Fe−Ni nanoparticles, which catalyze formation of the nanosized carbon materials, are produced spontaneously. This process is simple and easily scaled up; therefore, mass production of the nanosized carbon materials is realizable. The formation mechanism for each nanostructure is also proposed in this paper.

Highly Reliable Operation of High-Power InGaAsP/InGaP/AlGaAs 0.8 µ m Separate Confinement Heterostructure Lasers (1995)

We report the high-power and reliable operation of InGaAsP/InGaP/AlGaAs 0.8 µ m separate confinement heterostructure single-quantum-well laser diodes. High output power of 1.8 W is achieved from an anti-reflection- and high-reflection-coated device with stripe width of 50 µ m and cavity length of 1.25 mm. This device has high characteristic temperature of 164 K and low threshold current density of 300 A/cm 2 . No catastrophic failure in the laser with 0.75 mm cavity length is observed during 1000 h aging test at 50° C under an automatic power control of 500 mW. The effect of cavity length on laser characteristics is also discussed.
The Effects of In Flow during Growth Interruption on the Optical Properties of InGaN Multiple Quantum Wells Grown by Low Pressure Metalorganic Chemical Vapor Deposition (2001)

In 0.2 Ga 0.8 N/In 0.03 Ga 0.97 N 3-period multiple quantum wells (MQWs) were grown by low pressure metalorganic chemical vapor deposition and the effects of pre-In flow prior to QW growth on its overall optical property were investigated. Pre-In flow did not change the structural property of the MQW structure such as In composition and period but strongly influenced its optical properties. MQW samples grown with pre-In flow exhibited longer peak wavelength and stronger peak intensity. CL measurement revealed more uniform and smaller emission centers in pre-In flow samples, implying a reduction of non-radiative defective regions and more In-rich regions. These results indicate that the In source introduced prior to QW growth preferentially gets incorporated around defect sites such as threading dislocations to inhibit their propagation while forming seeds for In-rich regions.
Compact optical trapping microscope using a diode laser (2000)

Single beam gradient force optical trapping (laser tweezers) is increasing in importance as a technique for microparticle and cell manipulation and for the measurement of piconewton forces in aqueous media. An optical trap constructed using an optical microscope and a diode laser is described here. The system incorporates novel beam steering optics allowing the positioning of the trapping spot within the field of view of the microscope. Despite its full functionality the system is compact, portable, relatively inexpensive and easy to construct and operate. A new scheme for trapping force calibration is also reported and measurements compared to theoretical results. The trapping efficiency is found to be similar to that obtained when using other trapping systems.
Peach, Control of American Plum Borer and Sesiid Borers with Chemical Insecticides and an Ento-Mopathogenic Nematode, 1995 (1996)

Abstract Trials were conducted in a 25-year-old commercial block of peaches severely infected with a canker disease, providing openings through the bark attractive to borers. Most cankers were filled with gum. Five single-tree replicates of each treatment were selected based on likelihood of borer infestation. All materials were applied as a coarse spray with a handgun sprayer at 400 psi. The spray stream was directed into openings in the bark, as well as covering the entire trunk, from ground level up to, and including, the first scaffold limbs. Spray dates for Lorsban were 7 Jun (petal fall) or 7 Jun + 13 Jul (APB 2nd flight start). Spray dates for Asana were 7 Jun, or 7 Jun + 13 Jul + 15 Aug (postharvest). The nematode tested was Steinernema carpocapsae (Scanmask). Spray dates for Scanmask were 27 Jun (1st generation larvae present) or 27 Jun + 15 Aug (2nd generation larvae present). Trunks and lower scaffolds were sampled in the fall (28 Sep-4 Oct) by peeling back bark with a hammer and long screwdriver to slightly beyond the edge of the living cambium and counting all living larvae.
Enzyme technologies for alleviating lactose maldigestion / Tecnologías enzimáticas para aliviar la mala digestion de la lactosa (1997)

Lactose reduction in milk by β-galactosidase prior to consumption is one of the current modali ties of alleviating lactose maldigestion. However, hydrolysis of lactose results in flavour changes in milk: glucose and galactose are between three and four times sweeter than lactose, and many lactose maldigesters do not like the taste of lactose-hydrolysed milk. The addition of exogenous β-galactosidase to meals has been shown to alleviate lactose maldigestion adequately, and so β-galactosidase could be added to milk if the lactose could be protected from the hydrolytic action of the added enzyme. Liposomes, which have recently shown potential as carriers of enzymes, could be good vehicles for the addition of β-galactosidase to milk. β-galactosidase can be successfully encapsulated in liposomes which have been shown to be very stable when suspended in milk stored at refrigeration temperature. Lactose hydrolysis is minimal when liposomal β-galactosidase is added to milk. In vitro digestibility studies have shown that the liposomal β-galactosidase is available for digesting lactose in milk. Stable blends of β-galactosidase and dry milk powders have also been used. Results have shown that up to 95% of the original activity of the fungal lactase was retained in blends of the enzyme and milk powder when stored under nitrogen at 45 °C for 6 months.
Dihydropyrimidines and related structures. I. <i>N</i><sup>2</sup>‐substituted 2‐pyrimidinamines and dihydro‐2‐pyrimidinamines by reaction of phenylbutenones and monosubstituted guanidines (1984)

Abstract The reactions of monosubstituted guanidines 2 with phenylbutenones 7 and 10 exclusively yield N 2 ‐substituted 2‐pyrimidinamines 8 and 9 . The structure of the reaction products is proved and their differing stability is discussed. Action of methyl‐ and benzylguanidine respectively ( 2b, c ) on 4‐phenyl‐3‐buten‐2‐one ( 7 ) and of 2c on l‐phenyl‐2‐buten‐1‐one ( 10 ) under atmospheric oxygen affords aromatic N 2 ‐substituted 2‐pyrimidinamines 9b and c . The dihydropyrimidines 8b and c, probable intermediates of the reactions, could not be isolated. In contrast, heating of arylguanidines 2d , e with 7 leads to stable dihydropyrimidinarnines 8d and e, which can be isolated as bases. Addition of methanol to 8d yields 6‐methoxy‐2‐pyrimidinamine 11d , boiling of 8d in DMF affords 9d . Under nitrogen, guanidine adds to 7 to yield aminopyrimidinol 13a , which is transformed by heating in benzene into pyrimidine 9a . The low stability of 8a‐c is attributed to their strong basicity, the greater stability of 8d and e to their lower basicity. The structural formulae of 8d , e and 9b‐d and their salts respectively were established partly ( 8e ) by nmr and partly ( 9b‐d ) by comparison of the corresponding picrates with authentic samples [17].
Simple determination of the herbicide napropamide in water and soil samples by room temperature phosphorescence (2005)

A new, simple, rapid and selective phosphorimetric method for determining napropamide is proposed which demonstrates the applicability of heavy-atom-induced room-temperature phosphorescence for analyzing pesticides in real samples. The phosphorescence signals are a consequence of intermolecular protection and are found exclusively with analytes in the presence of heavy atom salts. Sodium sulfite was used as an oxygen scavenger to minimize room-temperature phosphorescence quenching. The determination was performed in 1 M potassium iodide and 6 mM sodium sulfite at 20 degrees C. The phosphorescence intensity was measured at 520 nm with excitation at 290 nm. Phosphorescence was easily developed, with a linear relation to concentration between 3.2 and 600.0 ng ml(-1) and a detection limit of 3.2 ng ml(-1). The method has been successfully applied to the analysis of napropamide in water and soil samples and an exhaustive interference study was also carried out to display the selectivity of the proposed method.

Novel cellulose derivatives. III. Thermal analysis of mixed esters with butyric and hexanoic acid (1995)

Abstract Cellulose derivatives with low degrees of substitution (i.e., DS < 1.5) often fail to reveal glass transition temperatures ( T g ) by virtue of their tenacious adherence to moisture, thus preventing systematic analysis of substituent effects (size and DS) on T g and T m transitions. On the other hand, cellulose triesters have T m s that decline with acyl substituent size except when the substituent size becomes very large (i.e., > C 6 ), and they have T g s within 5–20°C of their T m s. This proximity is unusual for a semicrystalline material, and it interferes with the crystallization process that occurs between T m and T g . Triesters of cellulose with mixed acyl substituents (one smaller and one larger) allow not only unambiguous observation of T g s and T m s but also an adjustable Δ( T m − T g ) window that depends upon the size and the DS of the larger substituent. The materials studied including cellulose acetate butyrate triesters (DS bu 0.8–2.6), cellulose acetate hexanoate triesters (DS hex 0–3.0), and cellulose acetate (DS ac 2.44), revealed that only the mixed esters, in which the bulkier acyl group is in the range of DS 0.3–1.0, had a Δ( T m − T g ) value in excess of 40°C. Although the T m of cellulose acetate hexanoate declined by ca. 150°C per unit of DS hex as DS hex rose from 0 to 1, this was only ca. 25°C between DS hex of 1 and 3. Frequently observed dual‐melt endotherms were attributed to two separate crystal morphologies. ©1995 John Wiley & Sons, Inc.
BitTorrent Sync: Network Investigation Methodology (2014)

The volume of personal information and data most Internet users find themselves amassing is ever increasing, and the fast pace of the modern world results in most people requiring instant access to their files. Millions of these users turn to cloudbased file synchronisation services, such as Dropbox, Microsoft SkyDrive, Apple iCloud and Google Drive, to enable "alwayson" access to their most up-to-date data from any computer or mobile device with an Internet connection. The prevalence of recent articles regarding invasion of privacy issues and data protection breaches in the media has caused many to review their online personal data security practices. To provide an alternative to cloud-based file backup and synchronisation, BitTorrent Inc. released an alternative cloudless file backup and synchronisation service, named BitTorrent Sync in April 2013. BitTorrent Sync's popularity rose dramatically throughout 2013, reaching over two million active users by the end of the year. This paper outlines a number of scenarios where the network investigation of the service may prove invaluable as part of a digital forensic investigation. An investigation methodology is proposed outlining the required steps involved in retrieving digital evidence from the network and the results from a proof of concept investigation are presented.
Effect of Enteric Coating on Antiplatelet Activity of Low-Dose Aspirin in Healthy Volunteers (2006)

Equivalent doses of the enteric-coated aspirin were not as effective as plain aspirin. Lower bioavailability of these preparations and poor absorption from the higher pH environment of the small intestine may result in inadequate platelet inhibition, particularly in heavier subjects.
YOHIMBINE FOR ERECTILE DYSFUNCTION: A SYSTEMATIC REVIEW AND META-ANALYSIS OF RANDOMIZED CLINICAL TRIALS (1998)

The benefit of yohimbine medication for erectile dysfunction seems to outweigh its risks. Therefore, yohimbine is believed to be a reasonable therapeutic option for erectile dysfunction that should be considered as initial pharmacological intervention.
Ultrafast nonlinear refraction in an active MQW waveguide (1993)

The first assessment of a fast and relatively strong refractive optical nonlinearity in a MQW active waveguide operated at its material transparency current is presented. A large nonlinear figure of merit together with large phase shifts are demonstrated, indicating considerable promise for all-optical switching at speeds approaching 1 Tbit/s.
Molecular cloning and biological characterization of the human excision repair gene ERCC-3. (1990)

In this report we present the cloning, partial characterization, and preliminary studies of the biological activity of a human gene, designated ERCC-3, involved in early steps of the nucleotide excision repair pathway. The gene was cloned after genomic DNA transfection of human (HeLa) chromosomal DNA together with dominant marker pSV3gptH to the UV-sensitive, incision-defective Chinese hamster ovary (CHO) mutant 27-1. This mutant belongs to complementation group 3 of repair-deficient rodent mutants. After selection of UV-resistant primary and secondary 27-1 transformants, human sequences associated with the induced UV resistance were rescued in cosmids from the DNA of a secondary transformant by using a linked dominant marker copy and human repetitive DNA as probes. From coinheritance analysis of the ERCC-3 region in independent transformants, we deduce that the gene has a size of 35 to 45 kilobases, of which one essential segment has so far been refractory to cloning. Conserved unique human sequences hybridizing to a 3.0-kilobase mRNA were used to isolate apparently full-length cDNA clones. Upon transfection to 27-1 cells, the ERCC-3 cDNA, inserted in a mammalian expression vector, induced specific and (virtually) complete correction of the UV sensitivity and unscheduled DNA synthesis of mutants of complementation group 3 with very high efficiency. Mutant 27-1 is, unlike other mutants of complementation group 3, also very sensitive toward small alkylating agents. This unique property of the mutant is not corrected by introduction of the ERCC-3 cDNA, indicating that it may be caused by an independent second mutation in another repair function. By hybridization to DNA of a human x rodent hybrid cell panel, the ERCC-3 gene was assigned to chromosome 2, in agreement with data based on cell fusion (L. H. Thompson, A. V. Carrano, K. Sato, E. P. Salazar, B. F. White, S. A. Stewart, J. L. Minkler, and M. J. Siciliano, Somat. Cell. Mol. Genet. 13:539-551, 1987).
