As an attempt to view Chason costume from a aesthetic perspective, the aesthetic values of the Choson people, as expressed through the aesthetic characteristics of costumes, are pursued in this study. To appreciate the beauty of the traditional Korean costume, the following aesthetic characteristics of Choson costumes are investigated: form, color, pattern, material and ornament. From the view point of aesthetics, this study shows that Choson costume had comfortable and voluminous forms with beautiful curved lines and rhythm. The most favored colors were white and natural colors of materials. However unusual combination of colors such as the contrast of black and white, the harmony of the primary and rainbow colors were often used. Patterns revealed two aspects : while subdued patterns generally prevail, at times the unexpected beauty of primary colored patterns draws our attention. Smooth natural materials were preferred. Ornaments both for practical and decorative purposes were used together with certain colors and patterens, indicating wearer's status and warding off the evil's spirits. The aesthetic values in costumes as expressed through the aesthetic characteristics can be classified into the following categories: the beauty of nature, the beauty of personality, the aesthetics of evil's eye and the beauty of tradition. The beauty of nature, as appreciated by the Chason people through their prevailing nature, the "Pung-rew Spirit" and through their Worship of Heaven, produced aesthetic characteristics in harmony with nature. The beauty of personality influenced by the ethical standard of Confucianism produced aesthetic characteristics in costumes, through which the appropriate personality was shown for the appropriate social status. On the other hand, the aesthetics of evil's eye, rooted deeply in Folk religion and Shamanism, contributed to various aesthetic characteristics, which strongly inclined to sorcery and symbolism through choice of patterns, colors and ornaments. Finally, the beauty of tradition, which was based on the ethics of Confucianism and the Choson people's conservative tendencies, demonstrated the strong tendency to adhere to the external characteristics of the Choson costume. These aesthetic values were the yardsticks of the aesthetic judgment of the Choson people. These values influenced Chason people in designing costumes and in appreciating the beauty of costumes. The aesthetic experience and attitudes of the Chason people, which were based on these aesthetic values, represented their aesthetic consciousness and desires.

The rising trend of breast cancer both in developed and developing countries is a real threat challenging all efforts to screening, prevention and treatment aspects to reduce its impact. In spite of modern preventive strategies, the upward trend of breast cancer has become a matter of great concern in both developed and developing countries. Chittaranjan National Cancer Institute is a premier regional cancer institute in eastern region of India catering to a large number of cancer patients every year. A pilot case control study of fifty breast cancer patients and 100 matched controls was conducted during 2013 to evaluate the effects of habitual factors like working in night shift, not having adequate sleep, and not sleeping in total darkness on breast cancer of women. The study revealed that not sleeping in total darkness was associated with higher odds of outcome of breast cancer of women. This positive correlation can play a vital role in formulation of preventive strategies through life style modification.

The purposes of this study are to comprehend the internal meaning and the external form in style of Greek statue's clothing in the light of linked solution, and to compare the characterizations of style of Greek statue's clothing with those in Greek Art. For these purpose, the theoretical studies about Greek art are preceded as a framework of this research, and then plastic characteristics of Greek statue's clothing and Greek art are analyzed by the documentary studies, For sources, photographs of Greek statue in Archaeological Museum and Louvre museum are used. The result is as follows. It is demonstrated that the characters of internal meaning in style of Greek art and Greek statue's clothing. The internal meaning of style of Greek art and Greek statue's clothing are as follows 1) Beauty of vital is subject that possessed life and movement and embodied dynamics or inherent power. 2) Beauty of moderation is subject that achieves some of its most impressive and practise a similar economy and restraint. 3) Beauty of character is subject that reveals the character of its wearer and has its own charm and distinction The Greeks clarified beauty by looking for mathematical proportions. It is the interrelation of part with one another, and with the whole, together with the additional element of good colour, which constitutes beauty as perceived by the eyes. The beauty in style of Greek statue's clothing consists of a sense of geometrical pattern, oder, symmetry, proportion, and rhythm.

The current study observes the durational interaction of tautosyllabic consonants and vowels in the word-initial position of English and Korean child-directed speech (CDS). The effect of phonological laryngeal contrasts in stops on the following vowel duration, and the effect of the intrinsic vowel duration on the release duration of preceding stops in addition to the acoustic realization of the contrastive segments are explored in different prosodic contexts - phrase-initial/medial, focal accented/non-focused - in a marked speech style of CDS. A trade-off relationship between Voice Onset Time (VOT), as consonant release duration, and voicing phonation time, as vowel duration, reported from adult-to-adult speech, and patterns of durational variability are investigated in CDS of two languages with different linguistic rhythms, under systematically controlled prosodic contexts. Speech data were collected from four native English mothers and four native Korean mothers who were talking to their one-word staged infants. In addition to the acoustic measurements, the transformed delta measure is employed as a variability index of individual tokens. Results confirm the durational correlation between prevocalic consonants and following vowels. The interaction is revealed in a compensatory pattern such as longer VOTs followed by shorter vowel durations in both languages. An asymmetry is found in CV interaction in that the effect of consonant on vowel duration is greater than the VOT differences induced by the vowel. Prosodic effects are found such that the acoustic difference is enhanced between the contrastive segments under focal accent, supporting the paradigmatic strengthening effect. Positional variation, however, does not show any systematic effects on the variations of the measured acoustic quantities. Overall vowel duration and syllable duration are longer in English tokens but involve less variability across the prosodic variations. The constancy of syllable duration, therefore, is not found to be more strongly sustained in Korean CDS. The stylistic variation is discussed in relation to the listener under linguistic development in CDS.

The objective of this study is to develop naturalistic knit designs inspired by Yann Arthus-Bertrand's works. For this purpose, we examined the present style of naturalism and history of naturalism though literature research, and then developed designs. The results are as follows: First, as scientific realism originated from a philosophical concept was adopted in literature and other genres, its meanings have been altered and comprehensively expanded according to the genres of which the term is being used. Naturalism of the modern times carries strong message of ecology and environmental protection. Second, the modern naturalism in fashion is manifested in expressing the image of nature and plasticity, instead of a mere use of the natural materials. As the aspects of ecology become more significant, elements of retro, recycle, or grunge are additionally integrated in fashion. Third, Naturalism expressed in knitwear is similar with that of other clothing in terms of color and textile, however, silhouette in knitwear is unique in its general naturalness and flowing effects. Embroidery, knitting of Jacquard and Intarsia, or crochet is used to express forms of objects from nature. Visual effects regardless of the contents of yarn, and pattern effects after knitting by using yarn, have influences on the material. Forth, the eight knit designs in expressing naturalism presented in this study took a motif from the works of Yann Arthus-Bertrand. They were created by rendering rhythm of the landscape with emphasis on brown color. Contour and surface touch were expressed through yarn and the structure of knit.

The purpose of this study is to observe the brain activity patterns during visual oddball tasks with two difficulty levels by the analysis of high-density event-related potential (ERP). Along with conventional statistical analysis of averaged ERP waveforms, we applied independent component analysis (ICA) for the individual, single-trial analysis and verified its effectiveness. We could identify multiple ERP components such as early visual components (P1, N1), and two components which seem to be important task-related components and showed difficulty-dependent variability (P2, P300). The P2 was found around central region at $180{\sim}220ms$, and the P300 was found globally at $300{\sim}500ms$ poststimulus. As the task became difficult, the P2 amplitude increased, and the P300 amplitude decreased. After single-trial ERPs were decomposed into multiple independent components (ICs), several ICs resulting from P2 and P300 sources were identified. These ICs were projected onto scalp electrodes and the projected ICs were statistically compared according to two task difficulties. For most subjects, the results obtained from single-trial/individual analysis using ICA gave the tendencies of amplitude change that are similar to the averaged ERP analysis for most subjects. The temporal pattern and number of ICs corresponding to ${\mu}$ rhythm was not dependent on the task difficulty. It seems that the motor response was not affected by the task difficulty.

BACKGROUND: G protein-coupled receptors (GPCRs) are widely distributed in various organisms. Insect GPCRs shown as in vertebrate GPCRs are membrane receptors that coordinate or involve in various physiological processes such as learning/memory, development, locomotion, circadian rhythm, reproduction, etc. This study aimed to identify GPCRs expressed in fat body and compare the expression pattern of GPCRs in different temperature conditions. METHODS AND RESULTS: To identify GPCRs genes and compare their expression in different temperature conditions, total RNAs of fat body in Plutella xylostella larva were extracted and the transcriptomes have been analyzed via next generation sequencing method. From the fat body transcriptomes, genes that belong to GPCR Family A, B, and F were identified such as opsin, gonadotropin-releasing hormone receptor, neuropeptide F (NPF) receptor, muthuselah (Mth), diuretic hormone receptor, frizzled, etc. Under low temperature, expressions of GPCRs such as C-C chemokine receptor (CCR), opsin, prolactin-releasing peptide receptor, substance K receptor, Mth-like receptor, diuretic hormone receptor, frizzled and stan were higher than those at 25℃. They are involved in immunity, feeding, movement, odorant recognition, diuresis, and development. In contrast to the control (25℃), at high temperature GPCRs including CCR, gonadotropin-releasing hormone receptor, moody, NPF receptor, neuropeptide B1 receptor, frizzled and stan revealed higher expression whose biological functions are related to immunity, blood-brain barrier formation, feeding, learning, and reproduction. CONCLUSION: Transcriptome of fat body can provide understanding the pools of GPCRs. Identifications of fat body GPCRs may contribute to develop new targets for the control of insect pests.

Melody is defined as adding spatial dimension to the rhythm which is temporal concept. Being able to understand melodic pattern and to reproduce the pattern also requires cognitive skills. Since 1980, there has been much research on the relationship between academic skills and music cognitive skills, and how to transfer the skills learned in music work to the academic learning. The study purported to examine various research outcomes dealing with the correlational and causal relationships between musical and academic skills. The two dominating theories explaining the connection between two skills ares are "neural theory" and "near transfer theory." The theories focus mainly on the transference of spatial and temporal reasoning which are reinforced in the musical learning. The study reviewed the existing meta-analysis studies, which provided evidence for positive correlation between academic and musical skills, and significance of musical learning in academic skills. The study further examined specific skills area that musical learning is correlated, such as mathematics and reading. The research stated that among many mathematical concepts, proportional topics have the strongest correlation with musical skills. Also with reading, temporal processing also has strong relationship with auditory skills and motor skills, and further affect language and literacy ability. The study suggest that skills learned in the musical work can be transferred to other areas of learning and structured music activities may be every efficient for children for facilitating academic concepts.

BACKGROUND: In patients with acute heart failure (AHF), diastolic dysfunction, especially pseudonormal (PN) or restrictive filling pattern (RFP) of left ventricle (LV), is considered to be implicated in a poor prognosis. However, prognostic significance of diastolic dysfunction in patients with ischemic heart disease (IHD) has been rarely investigated in Korea. METHODS: We enrolled 138 patients with IHD presenting as AHF and sinus rhythm during echocardiographic study. Diastolic dysfunction of LV was graded as ${\geq}2$ (group 1) or 1 (group 2) according to usual algorithm using E/A ratio and deceleration time of mitral inflow, E'/A' ratio of tissue Doppler echocardiography and left atrial size. RESULTS: Patients in group 1 showed higher 2-year mortality rate ($36.2%{\pm}6.7%$) than those in group 2 ($13.6%{\pm}4.5%$; p = 0.008). Two-year mortality rate of patient with LV ejection fraction (LVEF) < 40% ($26.8%{\pm}6.0%$) was not different from those with LVEF 40%-49% ($28.0%{\pm}8.0%$) or ${\geq}50%$ ($13.7%{\pm}7.4%$; p = 0.442). On univariate analysis, PN or RFP of LV, higher stage of chronic kidney disease (CKD) and higher New York Heart Association (NYHA) functional class were poor prognostic factors, but LVEF or older age ${\geq}75$ years did not predict 2-year mortality. On multivariate analysis, PN or RFP of LV (hazard ratio [HR], 2.52; 95% confidence interval [CI], 1.09-5.84; p = 0.031), higher stage of CKD (HR, 1.57; 95% CI, 1.14-2.17; p = 0.006) and higher NYHA functional class (HR, 1.81; 95% CI, 1.11-2.94; p = 0.017) were still significant prognostic factors for 2-year mortality. CONCLUSIONS: PN or RFP of LV was a more useful prognostic factor for long-term mortality than LVEF in patients with IHD presenting as AHF.

In order to determine the seasonal prevalence and population density of vector mosquitoes in Kyungpook Province, a survey based on average numbers of female mosquito per trap-night, were carried out during the period from May to November in 1984. Among the 34, 571 mosquitoes collected in Kyungsan county in animal shelters and human dwellings by light traps, approximately 45.0 per cent were Culex tritaeniorhynchus, 34.0 per cent Culex pipiens pallens, and 19.0 per cent Anopheles sinensis. By comparison, distribution of mosquito species in Ankang town, in which Japanese encephalitis had been reported in the past, were quite different and A. sinensis was the most abundant species, being constituted in 75.8 per cent, followed by C. tritaeniorhynchus(23.2 per cent), and C. pipiens pallens(O.6 per cent). In the general pattern of seasonal prevalence, C. tritaeniorhynchus first appeared in mid-June, and trapped in large numbers during the periods from mid-August to early September, showing a simple sharply pointed one-peaked curve, while C. pipiens pallens was found to be active through almost the entire season showing irregular curves with several peaks. The trend of seasonal distribution of A. sinensis was similar to that of C. tritaeniorhynchus, but the earliest dates of appearance and disappearance differed from that of C. tritaeniorhynchus. The results of hourly catches of mosquitoes by human baited traps have clearly shown the differences in the biting rhythm among the vector mosquitoes of this Province, such as the facts that C. tritaeniorhynchus and A. sinensis are rather constantly active all through a night with more or less inconspicuous peaks twice a night, while C. pipiens pallens exhibits an irregular curve, and the numbers of A. vexans nipponii, C. vagans and Armigeres subalbatus are very small and are not sufficient for estimating the biting rhythm. Four genera and fourteen species of larval mosquitoes collected from eighteen kinds of habitats which classified according to the categories followed by Bates (1949). The main breeding sites contributing to peak C. tritaeniorhynchus adult densities in this surveyed areas were evidently ricefields, ground pools, puddles and swamps and marshes, etc. Summarizing the results, this study indicated that the highest population density of C. tritaeniorhynchus was encountered in late August and early September, showing a simple sharply pointed one-peaked curve.
