In this paper, a method of estimating hand and elbow movements using electrocorticogram (ECoG) signals is proposed. Using multiple channels, surface electromyogram (EMG) signals and ECoG signals were obtained from patients simultaneously. The estimated movements were those to close and then open the hand and those to bend the elbow inward. The patients were encouraged to perform the movements in accordance with their free will instead of after being induced by external stimuli. Surface EMG signals were used to find movement time points, and ECoG signals were used to estimate the movements. To extract the characteristics of the individual movements, the ECoG signals were divided into a total of six bands (the entire band and the ${\delta}$, ${\Theta}$, ${\alpha}$, ${\beta}$, and ${\gamma}$ bands) to obtain the information entropy, and the maximum likelihood estimation method was used to estimate the movements. The results of the experiment showed the performance averaged 74% when the ECoG of the gamma band was used, which was higher than that when other bands were used, and higher estimation success rates were shown in the gamma band than in other bands. The time of the movements was divided into three time sections based on movement time points, and the "before" section, which included the readiness potential, was compared with the "onset" section. In the "before" section and the "onset" section, estimation success rates were 66% and 65%, respectively, and thus it was determined that the readiness potential could be used.
A number of organizations have had big interests in studies concerning leadership and not only academia but also psychological areas do also. Until now, leadership has been accentuated by managers or team leaders especially. Recently, however, the concept of self-leadership directing one's own activities through self-control or self-management is being focused on in practices and in academia. This study is to investigate the influence between self-leadership strategies as predictors and learning performance in IT classes as dependents variables mediated by attitude of attendance focused on the social science students in two universities (Korea(116 samples) and India(36 samples)). And this research tried to compare difference between two university students. As a result of empirical analysis, Korean learners making an effort by themselves show a tendency to think constructively. Namely, even though the level of difficulty may be high, by positive self-talk, respondents usually make an effort to get high academic performance. In case of Indian respondents, students who are in behavior-oriented show higher academic performance. Research results can give us direction of task-taking attitudes in firms or learning attitudes in teaching organizations and implications to human resource managers who are in charge of improving learning performance or productivity.
A human being makes a constant effort to find out what he really is. We try to do a great deal in self-culture to know his own self-nature with miscellaneous ways as Buddhism, Taoism and Confucianism. When we are faced with a difficult problem in life, We utilize own knowledge and wisdom to solve them. Thus there are many result of answer what self-confidence is throughout the devoting oneself to the study of man's life which is expressed poetry and prose. We can see the aspect of liberty life in their poetry and prose which is escaping from their restraints as they are willing to find out their own self-nature and want to attain a state of perfect self-nature in every day life. And they are anxious to be born again in spiritual value and to be a man in liberty with removing the narrow-mindedness, the stupidity, the anger and the absolute ego in their mind. That's what we are want to achieve man's purpose understanding of the human being's life. Here, I have a good such example who is Tao yuan ming. It is not easy to give up fame and wealth for maintaining his doctrines. So We have a high regard for this wisdom between entering into politics and withdrawing from his office. It needs a self-conquest and more courage than entering into politics. Retiring from his office, he returns to the place where is native place everything lives and let live without moral pressure in daily life. Because there is real liberty life and immutable truths.
We designed optical systems for a mobile phone camera using a spherical SELFOC lens and an aspherical plastic lens. Since the radial index distribution gives an additional design parameter for optical design, an aspheric lens could be replaced by a spherical lens. The imaging performances of the design were compared with conventional 2P design composed of two aspherical plastic lenses. In the first stage of study, we designed 1GRIN 1P lenses by using commercially available SELFOC materials. But, the conventional 2P lenses had better performance than the 1GRIN 1P lenses. In the 1GRIN 1P designs, the performance depends on index variation of GRIN material, the larger variation gives the better performance. Hence, we tried to design by using fictitious GRIN materials which have large index variation. We found if the index variation could be increased to about 3 times that of currently available SELFOC materials, the 1GRIN 1P lens will have equivalent or better performance than the conventional 2P design.
In order to reveal the differentiation of Nietzsche's justice theory, this paper attempted an intrinsic analysis of the political act of establishing a social contract with others through the fundamental concept of "will to the power", and the politics of modern nation including utilitarianism, liberalism and democracy. I will deal with criticism of ideology. In other words, it will be a work to clarify the fictitiousness and errors by digging out the ground of the value of justice as 'genealogical psychology' which strips off the psychological layers hidden behind the name of universal truth called 'virtue'. By dismantling the notion of self-righteous justice based on 'virtue' from 'immorality' as well as 'out of morality', it aims to reveal a new emotional dimension based on love, not retaliation. When Nietzsche emphasizes the role of positive emotions such as 'mercy' and 'forgiveness' rather than negative emotions such as revenge, retaliation, and grudge, while analyzing justice in the dynamics of power relations, By allowing exception rule, we will critically analyze whether universality and consistency are lost.
The purpose of this study is to identify the influence of users' satisfaction with the Automatic Writing Evaluation(AWE) on learners' sense of learning achievement through self efficacy in English writing class. AWE is a tool that automatically provides feedback on writing outputs by AI technology. College students were asked to write essays for each topic and use AWE to get feedback on their drafts, and finally revise them referring to the feedback. A questionnaire survey was conducted for the data collection. The data was analyzed using SPSS, and smart PLS-SEM along with bootstrapping techniques, The results of the study reveal the followings: 1) the convenience and usefulness of AWE had a positive effect on the willingness to reuse it; 2) the satisfaction with AWE had a positive effect on self-efficacy; 3) self-efficacy had a positive effect on learning achievement in terms of emotional and linguistic aspects. With the development of the 4th industry and A.I. technology, it is recommended to introduce new materials or programs such as AWE in English education.
The current study investigates how Malaysian ESL learners' L2 (English) speaking fluency is reflected in advanced L2 reading and what difficulties they encounter in reading comprehension. Nine Malaysian students attending a Korean university participated in qualitative research using in-depth and semi-structured interviews. The data revealed that L2 was a very familiar language, and their speaking fluency in L2 reduced the anxiety of L2 reading in general. However, it did not play a significant role in reading at an advanced level. Their difficulties in reading were mainly due to a lack of vocabulary knowledge. However, insufficient background knowledge and interest also frustrated their reading tasks. These factors lowered their reading comprehension, causing inaccurate interpretations or discouraging their endeavors to find messages from the given text. Thus, these findings should be carefully addressed in reading classes for Korean L2 learners as well as international students.

This study aims to identify petit bourgeois desires through the characters in "Oksosun Stories" from Cheonyerok, an eighteenth-century Yadam anthology. The desires and motivations of the characters are quite secular and egocentric. Because of this, their shared characteristics are similar to those of the petit bourgeois, as neutral existence begins to emerge during the transition from feudal to modern society. The concept of petit bourgeois generally means the public and the working class of modern society. The main character's behavior in the story differs little from general petit bourgeois attitudes. An important belief in petit bourgeois is not the ruling ideology in society but the achievement and stability of realistic and ordinary desires to fulfill their lives' satisfaction. Also selfish or antisocial attitudes and boundary characteristics appear in the process, depending on whether subject having any desire. However, the character's actions are limited in the governance system of a huge reality. And It is characterized by end goal being to meet their upward mobility and stability. This corresponds with Seang's (書生) actions of turning his back on his family and country as well as promising Jaran his love; and, he redeems himself with his family and society by acquiring stability after he passed the state examination. Furthermore, the contemporary significance of this work demonstrates Seang (書生) discovering his desires for human love; therefore, in order to affirm and gratify this desire, he endures the societal state of semi-feudalism against filial duty (不孝), disloyalty (不忠), and non-chastity (不烈), and he acts independently. In addition, on the strength of his pursuit of his desires, Oksosun frees herself from the caste restraint called gisaeng (妓生) and affirms her desire to become a subject of love, but she then deviates from the social system. Moreover, the limitations and achievements of the petit bourgeois are indicated in the actions of recognizing the social threshold of their past in the process, making independent efforts using their capabilities, fulfilling success in the state examination with their intellectual capacity, and re-entering society. From the late Chosun Dynasty to modern times, there is not only the type of contemporary people who hunger for fulfillment of their personal desire and live in free will, but there is also the feudal type that is still lacking in the understanding of independent life. This is not as different as in these present times. This literature asserts the meaning of awakening one's self-existence and assigning great value to the fulfillment of self-desires against the odds that are created by socio-political, cultural, economic norms of the era. "Oksosun Story" affirms the small efforts and successes of private individuals in reality. It also validates the search for life happiness through positivity. In this sense, even the contemporary reader would derive valid meaningfulness from this literature.

This study aimed at carrying out a semantic interpretation of the core Design language that seemed to influence deeply in the creation of the ChwuiseokJeong wonlim of Gochang. Especially, this paper aimed at inferring how the spiritual culture of seclusion of the 16th century influenced the creation of the wonlim by understanding the metaphor and symbolism by grasping the transmission meaning and reception meaning of the creators and the people concerned with keywords like Eunil(隱逸: seclusion), Chwuiseok(醉石), and Chilseongam(七星巖). 'Building up a wall' was intentionally carried out in order to represent 'Seven Stars(The Big Dipper)' inside of the wonlim. This is a kind of two-dimensional 'enframement', and a result of active creation of a meaningful landscape. From Chilseongam that was created by assembling, we presumed that Kyung-Hee Kim, Nohgye(蘆溪), the creator showed the recognition and thoughts of astronomy as a Confucian scholar that the ChwuiseokJeong Wonlim where he secluded is the center of the universe. The interpretation of words in Nohgyezip, an anthology, showed that the articles and writtings of Nohgye, his decsendants, and the people of ChwuiseokJeong included alcohols, Chwuiseok, Yeon-Myung Do, and Yuli(栗里) where Do secluded; this means that Nohgye ranked himself with Do because Nohgye also lived in peace by drinking alcohols and enjoying nature like Do did. 'Drinking' was what expressed the mind of Nohgye who wanted to be free and have the joy of enjoying mountains, water, and their landscape like Do did. In other words, 'Drinking' is the symbol of freedom that makes him forget himself and equate himself with nature. These are the representation, imitation, and mimesis of respecting Yeon-Myung Do. As the alegory of 'speaking something with other things' suggested, it is possible to read 'Chwuiseok', came from the story of Yeon-Myung Do, in multiple ways; it superficially points out 'a rock on which he laid when he was drinking', but it also can be interpreted as 'an object' that made him forget his personal troubles. In addition, it means freewill protecting unselfish mind with the spiritual aberration of drinking, 'Chwui(醉)', mentally; also, it can be interpreted metaphorically and broadly as a tool that makes Nohgye reach to the state of nature by the satisfied mind of Yeon-Myung Do. 'Chwuiseok' was a design language that showed the situation of Nohgye by comparing his mind with the mind of Yeon-Myung Do from the Confucian point of view, and a kind of behavioral mimesis based on his respect to Do and 'aesthetic representation of objective reality.' It is not coincidental that this mimesis was shown in the engraved words on Chwuiseok and the creation of ChwuiseokJeong that has the same name with Chwuiseok in Korea and China.
