The purpose of this study was to investigate whether the orientation of the head position across different categories affect reaction time and accuracy of object recognition. Fifty four right handed undergraduate students were participated in the experiment. Participants performed the word-picture matching tasks, which were different in terms of head direction of object (i.e., Left-headed or Right-headed) and object category (i.e., natural : animal or artificial : tool). Participants were asked to decide whether each picture matched the word which was followed by the picture. For accuracy, no statistically significant difference was found for both animal and tool pictures due to the ceiling effect. Interaction effect of category and orientation were statistically significant, whereas only the main effect of category was significant. In the animal condition, faster reaction times were observed for left to right than right to left presentation, while no statistical significant difference was found in the tool condition. The orientation of the object's canonical representation was different across different categories. The faster RT for the animal condition implies that the canonical representation for animal is left-headed. This could be due to the orientation of the face.

The Pansori is a Korean traditional vocal music that has a unique story and melody which converts deep emotion into art. It has both verbal and emotional components. which can be coordinated by large-scale neural network. The purpose of this study is to illustrate the cortical network activated by a Korean traditional opera, Pansori, with different emotional valence using functional MRI (fMRI).Nine right-handed volunteers participated. Their mean age was 25.3 and the mean modified Edinburgh score was +90.1. Activation tasks were designed for the subjects to passively listen to the two parts of Pansories with sad or hilarious emotional valence. White noise was introduced during the control periods. Imaging was conducted on a 1.5T Siemens Vision Vision scanner. Single-shot echoplanar fMRI scans (TR/TE 3840/40 ms, flip angle 90, FOV 220, 64 x 64 matrix, 6mm thickness) were acquired in 20 contiguous slices. Imaging data were motion-corrected, coregistered, normalized, and smoothed using SPM-96 software.Bilateral posterior temporal regions were activated in both of Pansori tasks, but different asymmetry between the tasks was found. The Pansori with sad emotion showed more activation in the light superior temporal regions as well as the right inferior frontal and the orbitofrontal areas than in the right superior temporal regions as well as the right inferior frontal and the orbitofrontal areas than in the left side. In the Pansori with hilarious emotion, there was a remarkable activation in the left hemisphere especially at the posterior temporal and the temporooccipital regions as well as in the left inferior and the prefrontal areas. After subtraction between two tasks, the sad Pansori showed more activation in the right temporoparietal and the orbitofrontal areas, in contrast, the one with hilarious emotion showed more activation in the left temporal and the prefrontal areas. These results suggested that different hemispheric asymmetry and cortical areas are subserved for the processing of different emotional valences carried by the Pansories.

This study examined 24 right-handed amateur baseball players. Twelve who had played baseball for more than 6 years were grouped as skilled players, while 12 who had played for 1-3 years were the unskilled player group. The swing motion was divided into four event phases: stance, backswing, impact, and follow-through. The mean and maximum plantar pressure, center of pressure, and ground reaction force were measured during each event phase. The mean and standard deviations for each variables were calculated and differences were validated with the independent sample t-test. A p-value <0.05 was considered statistically significant. The results were as follows. 1)The ideal stance is a stable, balanced position with more than 65% of weight on the right foot. There was significant difference in mean left plantar pressure, while the maximal plantar pressure and mean right plantar pressure did not differ significant. 2)The effective backswing of a skilled player is comprised a rightward shift in weight to build maximum energy. More than 90% of the weight was on the right foot. There was a significant difference in the mean left plantar pressure, while the maximal plantar pressure and mean right plantar pressure did not differ significantly. 3) For an effective impact, a rapid shift in weight to the left foot is essential, so that a power hit is obtained. Significant difference in the mean and maximum plantar pressures of both feet were observed. 4)Follow-through requires wight balance, more on the right than the left, without leaning leftward. There was no significant difference in the mean or maximum plantar pressure. 5)The center of plantar pressure should move from the center of the foot to the toe. 6)The analyses of the ground reaction force suggest that a good swing involves a gradual shift in weight to the right side and a rapid leftward shift at impact. Good balance, with the center of gravity on the right side at follow-through, is also required.

An ad endorser's gaze direction is a salient nonverbal cue that consumers use in responding to advertisements. The gaze direction influences consumers' social perceptions (e.g., attractiveness, credibility) of the endorser and advertising effectiveness (e.g., advertising attitudes, brand attitudes). Especially, the cerebral emotional asymmetry hypothesis suggests that an ad endorser's left-averted gaze can produce more positive social perceptions and advertising effectiveness than the right-averted gaze for right-handed consumers. This study examined the effects of three gaze directions (direct, left-averted and right-averted gaze directions) of unknown female ad endorser on Korean males' advertising responses (attractiveness-, credibility- and ad-effectiveness-related responses), using online experimental method. The results indicated that the ad endorser's direct gaze was more likely to increase both positive (correspondence bias) and negative (suspicion, deceptiveness) social perceptions of her than the right-averted gaze. The direct gaze also created more positive advertising effectiveness (advertising attitudes) than the right-averted gaze. However, the study failed to find consistent differences in responses between left-averted gaze and either direct or right-averted gaze.

In this paper, a switchable circularly polarized microstrip patch antenna using PIN diodes and corner slots on ground plane is proposed at 2.4 GHz. The proposed antenna has a square microstrip patch and ground plane that consists of two pair of slots and PIN diodes. The electrical lengths of the slots are adjusted by using the switching characteristic of the PIN diode, so the polarization of the proposed antenna can be switchable between linear, left-handed(LH) and right-handed(RH). By separating the ground plane for the DC bias, the size reduction effect is also obtained. When the proposed antenna is operated as linear polarization, the return loss and impedance bandwidth are 15 dB, 59 MHz, and when operated as LH and RH polarization, the minimum axial ratio and 3-dB axial ratio bandwidth are 1.17 dB, 1.67 dB, 28 MHz, and 32 MHz, respectively.

Three kinds of hydroxypropyl cellulose (HPC) derivatives: 6- (cholesteryloxycarbonyl) pentoxypropyl celluloses(CHPCs) with degree of esterification(DE) ranging from 0.6 to 3, 6-[4-{4'-(nitrophenylazo)phenoxycarbonyl}] pentoxypropyl celluloses (NHPCs) with DE ranging from 0.4 to 3, and fully 6-(cholesteryloxycarbonyl) pentanoated NHPCs (CNHPCs) were synthesized, and their thermotropic liquid crystalline properties were investigated. All the CHPCs and NHPCs with $DE{\leq}1.7$ formed enantiotropic cholesteric phases, whereas CNHPCs with 6-(cholesteryloxycarbonyl) pentanoyl DE(DEC) more than 1.6 exhibited monotropic cholesteric phases. On the other hand, NHPCs with $DE{\geq}2.4$ and CNHPCs with $DEC{\leq}1.3$ showed monotropic nematic phases. NHPCs with $DE{\leq}l$, as well as HPC, formed right-handed helices whose optical pitches (${{\lambda}_m}'s$) increase with temperature, while all the CHPCs formed left-handed helices whose ${{\lambda}_m}'s$ decrease with temperature. In contrast with these derivatives, NHPCs with $1.4{\leq}DE{\leq}1.7$ and CNHPCs with $DEC{\geq}1.6$ did not display reflection colors over the full cholesteric range, suggesting that the helical twisting power of the cellulose chain and the cholesteryl group highly depends on the chemical structure and DE of mesogenic group.

In this article, the elements usually included in the official documents issued by the Chosun Governor General office, the process of a certain document being put together and legally authorized, and its path of circulation and preservation are all examined. In order to create an official document of the Governor General office with legal authorization, a draft of a bill had to go through several discussions and a subsequent agreement before it was finally approved. Personnels involved in the discussion stage had the authority to ask for modifications and retouching of the draft, and the modifying process were all recorded in order to make clear who was responsible for a certain change or who objected to what at any given stage of the process. The approved version of an official document was called the 'Completed one(成案), and it was issued after the contents were turned into a fair copy by the office that originated the draft in the first place. With the original finalized version left in custody of that office, the fair copy was handed over to the Document department which was responsible for issuing outgoing documents. After the document was issued and the contained orders were carried out, the originally involved offices began to classify the documents according to their own standards and measures for safekeeping, but it was the Document department that was mainly responsible for document preservation. The Document department classified the documents according to related offices, nature of the documents(편찬류별), and most suitable preservation methods(보존종별). The documents were made into books, and documents to be permanently destroyed were handed over to the Account office where they would be demolished. The manners of document processing of the Chosun Governor General office was in fact a modified version of the manners of the Japanese government. Modifications were made so that the process would be more suitable to the situations and environment of the Chosun society. The office's managing process was inherited by the Chosun government after the Liberation, and cast a significant impact upon the document managing manners of the Korean authorities. The official document administration of the Chosun Governor General office marked both the beginning of the colony document administration, and also the beginning of a modernized document managing system.

Objective : The aim of current investigation was to standardize the grip strength of elders and to examine the correlation between grip strength, anthropometric parameters, depression and quality of life. Method : The researchers used Korea national health and nutrition examination surveys (2016) for analysis and analyzed the data of 919 elders who had completed the screening test among right-handed elderly without activity limitation. The researchers classified the age of the elders as 65~69, 70~74, 75~79, and 80 years old for standardization of grip strength. Anthropometric parameters are height, weight, body mass index, and waist circumference. Depression was measured by PHQ-9(Patient Health Questionnaire-9) and quality of life was assessed by EQ-5D. Result : The ratio of right handedness of the elderly was 87.8%, left handed 4.9%, and both handles 5.7%. In the standardization and correlation analysis, the grip strength decreased with age (p<.01, r=-.308~-.305). The grip strength showed a strong correlation with height (p<.001, r=.747~.741). There was a significant correlation between depression (p<.01, r=-.172~-.163) and quality of life (p<.01, r=.285~.267). Conclusion : The findings of this investigation suggest that height, depression, and quality of life need to be considered when assessing the level of grip strength in the elderly.

In the 1640's and 1650's, Milton wrote many prose works on a variety of topics such as education, church polity, divorce, censorship, regicide, tithing, civil liberty, and blindness. Much of his prose shows us turbulent decades of English history. In this period, he also published his first collection of poems and wrote sonnets. He wrote 23 sonnets in his life, and many sonnets Milton wrote after he had become Latin secretary are occasional poems in historical time. Milton's sonnets, as Annabel Patterson says, are a marker in his personal development, in his life, in his career as a writer, and in the history of his time. Four sonnets (15, 16, 17, 23), written between 1648 and 1655, were not published in the collected edition of Milton's poem in 1673. These sonnets, addressed to leaders of the Parliamentary party during the English revolution, Thomas Fairfax, Oliver Cromwell, and Henry Vane, and to his friend Cyriack Skinner, have been known as "commonwealth" sonnets. They are also called as "heroic sonnets" because they have the common style and theme with his later heroic epic poems. These sonnets were finally published in 1694 by Milton's nephew John Phillips. Milton was interested in religious, domestic, and political liberty for his lifetime, and his heroic sonnets also deal with these ideas of liberty. Milton asks civil liberty from Fairfax, freedom in religion from Cromwell, and from Vane for the reconciliation of both. The aim of this article is to examine how the rhetorical strategies of his "left-handed" prose interact with those of his "right-handed" poetry. This paper explores the relationship between Milton's heroic sonnets and his prose works, such as The Second Defense of the People of England, A Treatise of Civil Power, and The Likeliest Means to Remove Hirelings. Milton deals with the critical issues of religious tolerance, the separation of church and state, liberty of conscience and defense of his blindness, and attempts to define the statesman's role in peacetime England in these heroic sonnets and prose works.

Objectives: The objective of this study was to assess bra in activation and difference by LI11 or ST36 acupuncture stimulation using functional MRI (fMRI). Methods: A total of 10 healthy right-handed volunteers were studied. LI11 acupuncture and ST36 acupuncture stimulations were applied in order on the left. The block design paradigm of RARARA was used for the task, with R representing rest and A representing stimulation, and each period lasted 30 seconds. fMRI data were analyzed using SPM2. Results: The left LI11 acupuncture stimulation activated both sides of the inferior parietal lobule, the left side of the extra-nuclear, culmen and inferior semi-lunar lobules. On the right side, the nodule and midbrain regions were activated by the left LI11 acupuncture stimulation. The left ST36 acupuncture stimulation activated the right side of the superior frontal gyrus, middle frontal gyrus, superior parietal lobule, inferior semi-lunar lobule and pyramis. On the left side, the sub-gyral, middle temporal gyrus, fusiform gyrus, supramarginal gyrus, extra-nuclear, cingulate gyrus and fastigium regions were activated by the left ST36 acupuncture stimulation. Besides, both sides of the paracentral lobule, inferior parietal lobule, culmen, cerebellar tonsil and midbrain regions were activated. Conclusions: In conclusion, brain signal activation patterns according to acupoints were observed to differ, and ST36 acupuncture stimulation activated more regions than LI11. It is supposed that LI11 and ST36 acupuncture stimulations have an influence on motor function and sensory aphasia, and these stimulations thus represent potential for ocular motor dysfunction, discriminative touch or position sense disorder. Moreover, ST36 acupuncture stimulation activated the cingulate gyrus of the limbic system, so it seems to have an influence over autonomic functions.
