We prepared polymethyl methacrylate (PMMA) beads with a particle size of 80 nm to improve the energy conversion efficiency (ECE) by increasing the effective surface area and the dye absorption ability of the working electrodes (WEs) in a dye sensitized solar cell (DSSC). We prepared the TiO2 layer with PMMA beads of 0.0~1.0 wt%; then, finally, a DSSC with 0.45 cm2 active area was obtained. Optical microscopy, transmission electron microscopy, field emission scanning electron microscopy, and atomic force microscopy were used to characterize the microstructure of the TiO2 layer with PMMA. UV-VIS-NIR was used to determine the optical absorbance of the WEs with PMMA. A solar simulator and a potentiostat were used to determine the photovoltaic properties of the PMMA-added DSSC. Analysis of the microstructure showed that pores of 200 nm were formed by the decomposition of PMMA. Also, root mean square values linearly increased as more PMMA was added. The absorbance in the visible light regime was found to increase as the degree of PMMA dispersion increased. The ECE increased from 4.91% to 5.35% when the amount of PMMA beads added was increased from 0.0 to 0.4 wt%. However, the ECE decreased when more than 0.6 wt% of PMMA was added. Thus, adding a proper amount of PMMA to the TiO2 layer was determined to be an effective method for improving the ECE of a DSSC.

Oat! It entices us with its awesome components such as β-glucan and unsaturated fatty acid. This study was performed to investigate the changes of flour size distribution, pH, moisture content, Hunter color value, polyphenol, protein, flavonoid, lipid rancidity, β-glucan content and sensory evaluation of covered and naked oat flour that heated at 80, 120, 160 and 200℃. It was roasted for 5min to begin with, followed by complete cool, and for 10min at the second time. There was some difference in flour size distribution before and after of roasting. With increasing temperature, oat was more broken finely. For the Hunter b value representing the blackish color of the surface, after oats went through a roasting process, one went through until 160℃ showed same color statistically. Moisture content declined more as the roasting temperature became higher. As for pH, its range of variation was small from 6.2 to 6.6. While a polyphenol was on the reduction, protein was on the rise by the increase of temperature. In total, a flavonoid was declined at 80℃ but increased from 120 until 200℃ compared to control. A MAD (malonaldehyde) related with lipid acidification was statistically identical until 160℃ and sharply risen at 200℃. Roasting conditions had significant effect on β-glucan content. A covered oat’s β-glucan was declined as opposite to naked oat’s β-glucan with temperature being increased. Variation in sensory evaluation such as color, taste, smell and preference was observed. There is no statistically significant difference in specimens heated at 160℃ and 200℃ of covered and naked oat in sensory evaluation(p<5%). All things considered including MDA, β-glucan content and sensory evaluation, a optimum temperature for roasting oat to develop processed goods was verified as about 160℃.

This study was performed to investigate the content of carotenoid (α-carotene, β-carotene, β-cryptoxanthin, capxanthin, lutein, lycopene, zeaxanthin) and physicochemical characteristics (size, color, dietary fiber, total tannin content) of unripen and ripen persimmons (Diospyros kaki) by seven cultivars. The length of the unripen and ripen persimmons ranged from 40.87-64.75 and 48.80-80.29 cm, the width were from 44.03 to 66.73 and 57.65 to 91.53 cm, respectively. Ripen persimmons were showed in the highest Hunter’s L, a and b values. Total tannin content were resulted of unripen- and ripen persimmons ranged from 7.58 to 19.80 and 2.36 to 5.85 mg/g. Total carotenoid content were from 1.09 to 6.45 and 7.46 to 29.46 μg/g, respectively. From the above results, unripen- and ripen persimmon fruit could be useful for the health functional food.

Biological control has been tried for integrated pest management. It is often comparable, safe, and environment-friendly, making itself an alternative for chemical agents. Filamentous microorganisms, i.e., fungi and streptomystes, produce many kinds of useful metabolites, and some of them have been developed as a biocontrol agent. However, they still have a long way because of the concern of manufacturing cost. Therefore, process development was intensively studied to meet cost-effectiveness. Operating conditions of bioreactor, e.g., agitation and aeration, had an effect on biological and physiological responses such as mycelial morphology, oxygen and nutrient transfer. Understanding relationship between operating parameters and microbial responses in terms of growth, substrate and oxygen consumption, and production yield was critical for process development. This study dedicated to build strategies for mass production of biological control agent using aerobic filamentous microorganisms.

The present in vitro study was conducted to examine the effect of buffer solubility of eight protein feeds (coconut meal, distillers grain, sesame meal, perilla meal, soy source cake, rape seed meal, soybean meal and lupine) on the fermentation characteristics, degradability of dry matter (DM) and crude protein (CP), and methane (CH4) production by rumen microbes. Buffer extraction increased pH (P<0.05 ~ p<0.001) of the culture solution but tended to lower ammonia- N concentration for all protein feeds. Total volatile fatty acids(VFAs) and each VFAs concentrations in all incubation was decreased by buffer extraction (P<0.01 ~ P<0.001). Also, molar proportion of acetate in 1h (P<0.001), 3h (P<0.01) and 12h (P<0.05) incubations and molar proportion of propionate in 1h (P<0.001), 3h (P<0.01), 6h (P<0.05) and 12h (P<0.05) were decreased by buffer extraction. But molar proportion of butyrate in 1h (P<0.001), 3h (P<0.01) and 6h (P<0.05) were increased by buffer extraction. The in vitro effective degradability of dry matter (P<0.001) and CP (P<0.001) was decreased by buffer extraction. The methane production (P<0.01~P<0.001) in all incubation was decreased by buffer extraction. The results from in the current study might be useful for diet formulation to improve the feed efficiency of the ruminant animals without massive loss of major nutrients.

This study investigated the potential associations of dog characteristics with serum serotonin (5HT) concentration in dogs with degenerative mitral valve disease (DMVD). Client-owned dogs were prospectively recruited at the Veterinary Medical Teaching Hospital of Chungnam National University between 2010 and 2011. Forty-two dogs (22 females and 20 males) were enrolled in this study. DMVD dogs included Maltese (n=12), followed by Shih-tzu (n=10), mixed breed (n=5), Chihuahua (n=4), Miniature schnauzer (n=3), Miniature poodle (n=3), Miniature pinscher (n=1), Pomeranian (n=1), Yorkshire terrier (n=2), and Spitz (n=1). As inclusion criteria for the study, dogs had to show either direct or echocardiographic evidence of DMVD. Platelet count significantly differed among the three groups, as the moderate (P<0.05) and severe groups (P<0.05) showed significantly higher platelet counts than the mild DMVD group. Additionally, significantly higher LVIDd, LVIDs, fractional shortening (FS), and LA:Ao ratios were observed in dogs with moderate (P<0.05) and severe (P<0.05) DMVD compared to the mild group, respectively. Significant positive correlations between serum 5-hydroxytryptamine (5HT) concentration and platelet count (r=0.273, P=0.03), LA:Ao ratio (r=0.459, P=0.001), and LVIDd (r=0.319, P=0.013) were observed in DMVD dogs. Therefore, serum 5HT concentration may be a potential cause of DMVD progression.

This study examined the effects of learner-initiated noticing through comparison and teacher-initiated noticing through grammar instruction on EFL middle school learners' English writing process and uptake. For the study, 18 second-year middle school students with intermediate-high English proficiency were divided into three groups. After the first writing composition, one group (Group C) underwent a comparison stage, in which they compared their original writings and reformulated versions. Another group (Group I) received reactive grammar instruction on the four most frequent types of grammar errors, while the other group (Group IC) underwent both stages. All three groups revised their original writings in the next stage. To examine the learners' cognitive processes, think-aloud protocols were analyzed. The results showed that Group IC performed better in uptake than the other two groups, while no major differences were found between Groups I and C. This suggests that a mixture of learner-initiated noticing and teacher-initiated noticing influenced the learners' uptake.

Glucose is universal and essential fuel of energy metabolism and in the synthesis pathways of all mammalian cells. Glucose is the one of the major precursors of lactose synthesis using glycolysis result in producing milk fat and protein. During the milk fat synthesis, lipoprotein lipase (LPL) and CD36 are required for glucose uptake. Various morecules such as acyl-CoA synthetase 1 (ACSL1) activity of acetyl-CoA synthetase 2 (ACSS2), ACACA, FASN AGPAT6, GPAM, LPIN1 are closely related with milk fat synthesis. Additionally, glucose plays a major role for synthesizing lactose. Activations of lactose synthesize enzymes such as membranebound enzyme, beta-1,4-galactosyl transferase (B4GALT), glucose-6-phosphate dehydrogenase (G6PD) are changed by concentration of glucose in blood resulting change of amount of lactose production. Glucose transporters are a wide group of membrane proteins that facilitate the transport of glucose over a plasma membrane. There are 2 types of glucose transporters which consisted facilitative glucose transporters (GLUT); and sodium-dependent transport, mediated by the Na+/glucose cotransporters (SGLT). Among them, GLUT1, GLUT8, GLUT12, SGLT1, SGLT2 are main glucose transporters which involved in mammary gland development and milk synthesis. However, more studies are required for revealing clear mechanism and function of other unknown genes and transporters. Therefore, understanding of the mechanisms of glucose usage and its regulation in mammary gland is very essential for enhancing the glucose utilization in the mammary gland and improving dairy productivity and efficiency.

농촌사회의 소득수준 및 생활수준 향상과 더불어 농촌 공공공간 및 시설향상에 대한 요구는 지속적으로 제기되어 왔으며 이에따라 정부도 최근 다양한 방식의 농촌개발과 예산지원을 추진해오고 있다. 그러나 이러한 농촌 공공공간 및 시설의 지원 시 시설의 종류 및 입지 선정이 적절하지 않아 시설의 중복투자, 이용부족으로 인한 시설방치 등 다양한 문제점들이 제기되고 있다. 본 연구는 농촌마을에 분포하고 있는 다양한 공공공간 및 시설의 분포를 분석하고 이들에 대한 농촌마을의 유형별 중요도를 이해하는데 그 목적이 있다. 주요 연구방법으로는 100명을 대상으로 한 전문가 설문과 AHP(Analytic Hierarchy Process)를 이용하였으며 이를 통해 세 개의 농촌마을 유형 즉 거점면, 권역, 마을단위의 유형별로 주요 공공시설들간의 상대적 중요도를 분석하였다. 50개 마을을 분석한 결과 농촌마을에서 가장 일반적으로 발견되는 공공시설은 마을회관, 쉼터, 체험센터, 마을진입부, 안내시설로 나타났다. AHP는 세 단계의 비교로 이루어졌는데 첫 번째 마을유형별간의 쌍대비교에서는 거점면, 권역, 마을 순으로 중요도가 나타났다. 농촌 공공공간과 마을유형간의 쌍대비교에서는 모든 마을유형에서 기초생활시설, 문화 복지시설, 농촌관광시설, 소득시설의 순으로 중요도가 나타났다. 마을유형과 공공공간, 공공시설 등 각각의 가중치를 종 합한 중요도에서는 거점면의 경우 공동주차장의 중요성이 가장 높은 것으로 나타났고 다음으로 상수도시설, 공동화장실, 마을회관 순으로 나타났다. 권역에서는 공동주차장의 중요성이 가장 높았으며 다음으로 상수도시설, 체험센터, 마을회관 의 순으로 나타났다. 마을단위에서는 버스정류장이 가장 중요한 시설로 평가되었으며 다음으로 저수지, 하수처리장, 체 험센터의 순으로 나타났다. 본 연구는 비록 마을의 독특한 사회문화적 환경을 고려한 공공시설의 중요도 평가에는 한계를 안고 있으나 농촌마을에서의 공공시설 계획 시 마을유형의 특성을 고려한 시설의 상대적 중요도를 이해하고 이를 바탕으 로 적절한 시설을 선정하는데 도움을 줄 것으로 기대된다

Cultural content industry, which has its basis on sensitivities and creative activities of humans, is a newly rising industry, and its importance is getting more and more recognition. In order help it develop a different approach from those to other industries is needed. What should be noted about it is that, unlike other conventional manufacturing industries it values humans’ cultural creativity and that it is a high value-added industry. The cultural content industry is now positioning itself as an important axis of the drive for economic growth of South Korea. For this reason, it is necessary to systematically rearrange studies on the need for cultural content industry. For this the followings should precede: understanding of its development directions and a thorough knowledge about its characteristics, a close examination on the South Korean government’s promoting policies for cultural content industry, and effective policy establishment.

As a results of this study, Hold-Relax of PNF group are effective in improving muscular activity and gait factors

Importance-Performance Analysis(IPA) holds the assumption that the degree of physical fulfilment of quality attributes and the satisfaction of that attribute is linear. Therefore, IPA can be applied to the traditional one-dimensional attributes, not to other quality elements such as attractive or must-be attributes. To overcome this problem, several articles introduced methods that integrate IPA into the concept of two-dimensional quality. However, these articles are rather conceptual focusing on the differentiation of quality attributes depend on quality elements in IPA. To provide empirical evidence of the dependent relationship between attribute importance and satisfaction in IPA, this study introduces a weighted importance approach and provides validation method using Bacon(2003)’s priority model, a regression model. For this, the current research investigates 23 quality attributes of TV set for the results of Kano’s model, which are adopted from Kim et al.(2013), and conducted a survey of 118 university students for the results of the importance/satisfaction and improvement priority. The result of the proposed approach shows better result than those using the conventional way, based on R-square of the regression model.

Spectra of re ected sunlight from Mars and Jupiter are presented. They were obtained from an educational 1-D array spectrograph covering almost a full range of visible wavelengths, 200 ~ 900 nm with 1 nm spectral resolution. The question was whether a spectral difference could be obtained between that of terrestrial planets and gas planets with an educational spectrograph. It was installed in a 12-inch re ecting telescope at the Korea Science Academy of KAIST in Busan. Both spectra show clear absorption lines of re ected sunlight. They shows differences oin line presence, but are not very significant. This work means that the spectrograph successfully observed the re ected spectra of planets and can detect dierences in spectra in terms of the absence and presence of absorption lines of planets.

We present a color-magnitude (CM) diagram of M35, an open cluster. A DSLR camera was used for measuring the color index with the RGB channels. It is cost-effective and has relatively easy controls compared to astronomical CCDs for educational environments. The 8-inch refracting telescope was used at the Korea Science Academy of KAIST in Busan. The B-G color index was obtained from observations and the magnitudes from publications in order to draw CM diagram. The linear correlation of B-G to B-V is found. The RGB channel of the DSLR camera can be easily represented on the CM diagram for astronomical education with aid of easy controls.

Colors have been derived from the observed optical spectrum of Mars and Jupiter. It is known that the planets and the Moon emit re ected sunlight and thus their spectra are similar to the spectrum of solar radiation. The question was then why is the color of Mars different from that of other planets, i.e. red, although it would share the same spectrum of re ected sunlight. Can one derive color from the spectrum? Therefore, we observed the optical spectra of the scattered sunlight in day time for the Moon and Mars using a 1-D array spectrograph on the 12-inch reflecting telescope in the Korea Science Academy of KAIST in Busan, Korea. We adopted the International Commission on Illumination (CIE) in 1931 of three spectral sensitivity peaks for the human eye in short, medium and long wavelengths in visible light. The observed spectra were imposed on CIE sensitivities and the color detected by the human eye was derived. The Mars spectrum represents red color and the Moon white. It is a similar color to that which a human would see. This result means that color is easily derived from astronomical spectra. The appearance of the planets surface can be determined for Mars, which is the result of iron oxide.

I use a common educational spectrographic device (SV2100R) in order to obtain astronomical spec- tra after inventing a new adaptor for telescopes. Experimental classes and learning projects in schools and public outreach are well established regarding imaging and photometry observations. However, ex- periments using astronomical spectrographs are rather hard to find because the procedures of spectral extraction and wavelength calibration is less convenient. SV2100R is a 1D CCD array and thus has the advantage of not requiring spectral extraction. In addition, basic wavelength calibration is preformed by the the provided software. It was adapted to a 12-inch re ecting telescope in the Korea Science Academy of KAIST in Busan and a spectrum of the bright object, Arcturus, was successfully obtained. This means one can provide educational programs on the topic of astronomical spectra. A few suggested projects are presented.

The bdelloids collected from various terrestrial habitats such as mosses, lichens, mushrooms on tree trunks, leaf litter and soil at four different locations in Korea were investigated. Five bdelloids new to Korea were identified: Macrotrachella inermis Donner, 1965, Macrotrachela magna Schulte, 1954, Macrotrachela oblita Donner, 1949, Habrotrocha eremita (Bryce, 1894) and Habrotrocha schultei Donner, 1965. All these rotifers except M. inermis are new to Asia as well. Remarkably, these five Korean new records included four rare species with poorly known distributions. M. magna and H. schultei are recorded outside their type localities for the first time. M. oblita has been reported only from five European countries, and M. inermis has been known from three European countries and Eastern Turkey before the present study. The taxonomy and distribution of each rare bdelloid are discussed here.

Three growing wethers were used to investigate the differences in nitrogen (N) retention, blood plasma metabolite concentration and energy-yielding nutrient supply to muscle and adipose tissue. The wethers were fed one of three diets: timothy hay with concentrate (THD), Italian ryegrass with concentrate (IRD), and rice straw with concentrate (RSD) for 11 days. The experimental diets were adjusted to the animals to provide 100 g of daily gain. The triglyceride (TG) concentration of blood plasma in arterial and portal veins was higher with THD and IRD than with RSD. Conversely, the available amount of TG in tissues was higher with IRD. The daily amount of glucose and non-esterified fatty acids (NEFA) supplied to muscle tissue and adipose tissue was numerically higher with THD than IRD or RSD. Although N retention did not differ among the diets, it was numerically higher with THD than with IRD or RSD. The results suggest that the difference in the amount of glucose and NEFA delivered to muscle tissue may reflect the N retention in response to forage based diets.
