This study aimed to determine the effects of floral fragrances on human brain waves and moods. A total of 44 subjects participated in this experiment. Group 1 consisted of 11 male and 14 female college students with a mean age of 24.5 years (${\pm}2.23$) and Group 2 consisted of 10 males and 9 females with a mean age of 54.3 years (${\pm}2.98$). Subjects were exposed to floral fragrances of Rosa hybrida, 'Hera' (hereafter referred to as "rose"), Cymbidium faberi (hereafter referred to as "orchid"), or odorless control flowers (hereafter referred to as "control"). Experiments took place in three rooms (rose, orchid, and control). Electroencephalographs (EEGs) were recorded during exposure to the odors and the data were processed using quantitative electroencephalographic (QEEG) techniques. The changing EEG patterns were analyzed by brain mapping and compressed spectral arrays, and the subjects' preferences (hedonic evaluations) were quantified with an A1 index. Increased activation of absolute alpha waves was verified on six of the eight EEG channels, with the right frontal and left occipital lobes exhibiting no changes and the left parietal region showing the greatest activation. According to the QEEG measurements in the electrode sites over the frontal, temporal, parietal, and occipital lobes, the strongest absolute alpha waves were induced in the parietal lobes, followed by the temporal lobes, with the other lobes showing no significant changes. On brain maps, the orchid fragrance induced greater absolute alpha and absolute mid-beta activities compared with the rose and control fragrances, and the rose fragrance induced high absolute mid-beta activation. To identify emotional responses to floral fragrances, the subjects were requested to fill in a questionnaire and the resulting odor-related emotional descriptors were analyzed using semantic differential and factor analysis. Principal component analysis identified "elegant" as the first principal component describing the floral fragrance, followed by "refreshing" and "aromatic." The subjects gave orchid higher scores for "elegant" and "refreshing," while finding rose more "aromatic." Differences in hedonic evaluation revealed by the A1 index appeared in the 65-115 sec range of scent exposure time. The subjects with ages of around 50 years showed olfactory preferences throughout the entire experimental time of 160 sec, most markedly in the later time segment (115-165 sec), showing an increasing preference with increasing exposure time. We conclude that rose fragrance can improve concentration by creating an aromatic environment conducive to a concentrated and calm state of mind, and orchid fragrance can make people feel pampered and relaxed by creating an elegant and refreshing environment.
A pen name Chuman(秋巒; a mountain of Fall), Jeong Ji-wun(1509-1561) is a famous person wrote "Cheonmyeong-Doseol" which made two men, Yi Hwang and Ki Dae-$s{\breve{u}}ng$ dispute Sachil-Nobyeon(traditional argument about heart/mind). But except this point, few people of nowadays know who Jeong Ji-wun was. Therefore this paper is made for understanding Jeong Ji-wun in the point of view in history of thought. "Cheonmyeong-Doseol" by Jeong Ji-wun had systemized traditional theory of Cheonil-Habil(sky and human are an organic body), through this theory, Jeong Ji-wun had taken an important role who developed the Neo-Confucian theory in the field of political thought at that time. All Neo-Confucian literati used the theory of heart/mind as a sole useful method in political field from after King Myeonjong and Seonjo. "Cheonmyeong-Doseol" by Jeong Ji-wun was a first step to this scene. Especially "Cheonmyeong-Doseol" was got famous by arguments of Yi Hwang and Ki $Dae-s{\breve{u}}ng$, great scholars in the history of Chosun Dynasty. They firstly developed Sachil-Nobyeon, Sandan(pure morality) comes from li, Chiljeong(emotions) comes from Ch'i, is it right or not? This argument with "Cheonmyeong-Doseol" raised up the level of Neo-Confucian theory at that time. Like this, "Cheonmyeong-Doseol" was on the first step for Neo-Confucian literati to study and develop their theory of political thought which covered politics in Chosun Dynasty.

A joke (才談, 재담) is "the most interesting and witty language unit" in our speech. However, the search of a joke is still starting. Although joke are related to the witty and interesting talks, stories, songs and plays, the actual object of a joke is only the witty and interesting talk. A joke is witty talk that is interesting or laughter-inducing. Many Jokes can be found in the traditional Korean funny performing arts (演戱, 연희). This is because these art forms are performed in open yards, which necessitated amusing the audience, amusement, in its turn, required jokes. Jokes in the traditional funny performing arts can generally be classified as follows: 1) Jokes related to a situation: These include right words at a given situation, exaggerating words, diminishing words, deviancy words, and cause-effect words. 2) Jokes related to discourse: These include enumerating words, amplificatory words, contrasting words, fluently lying words, undeniable words, purposely unknowing words, and deliberately incorrect words. 3) Jokes related to vocabulary: These include synonym, similar words, changed word-ordering words, and incorrect words. 4) Jokes related to pronunciation: These include homonyms, and anti-homonyms. Although there may be other jokes, those presented above are typical ones. A joke is "the result that human being can achieve when he/she has overcome natural and social difficulties and is left with only a free and creative spirit." Jokes are necessary in all ages and everywhere. Today, more varied and high-level jokes can be created by developing the diversity of jokes in traditional funny performing arts. Also, I expect new sorts of jokes, because a joke always demands a creative spirit.

Harnesses are used in a variety of industries, such as rescue operations, medicine, and entertainment. However, conventional harnesses have problems as they are uncomfortable to wear and causes continuous pain. Therefore, in this study, the load and pressure applied to the body in the flying state when using a conventional harness were measured in real time and the distribution change was observed. Load and pressure were measured using a modified corset harness, a pressure sensor, and a human mannequin to measure the maximum and average pressure on the waist. As a result, it was confirmed that the load concentrated on the waist in the flying state was 104 N, and the pressure was applied to the left and right sides was 800 kPa or greater. The pressure distribution showed a pressure of 3-45 kPa in 73% in all measurable pressures. The results of the load and pressure distribution are presented as basic data for improving the wearability and reducing the discomfort of harnesses in the future, aid in the development of a harnesses that can minimize discomfort for various activities, and increase the concentration on experiential activities. In addition, using the CLO 3D program, which is a 3D virtual wearing system, a harness was put on a virtual model, and the compression level was checked and compared with the actual pressure distribution. As a result of comparing the measured pressure values in the flying state with the clothing pressure wearing the harness in the CLO 3D program, the total pressure value was found to be about 68% of the actual measured value. This helps develop a harness that can minimize discomfort during activities by predicting the load and pressure on the body by first applying new designs to a virtual wearing system during development. These new harness patterns can solve the problems of conventional harnesses.

Recently, We are carrying out a policy of physical distancing of at least 1m from each other to prevent the spreading of COVID-19 disease in public places. In this paper, we propose a method for measuring distances between people in real time and an automation system that recognizes objects that are within 1 meter of each other from stereo images acquired by drones or CCTVs according to the estimated distance. A problem with existing methods used to estimate distances between multiple objects is that they do not obtain three-dimensional information of objects using only one CCTV. his is because three-dimensional information is necessary to measure distances between people when they are right next to each other or overlap in two dimensional image. Furthermore, they use only the Bounding Box information to obtain the exact coordinates of human existence. Therefore, in this paper, to obtain the exact two-dimensional coordinate value in which a person exists, we extract a person's key point to detect the location, convert it to a three-dimensional coordinate value using Stereo Vision and Camera Calibration, and estimate the Euclidean distance between people. As a result of performing an experiment for estimating the accuracy of 3D coordinates and the distance between objects (persons), the average error within 0.098m was shown in the estimation of the distance between multiple people within 1m.

Purpose : Tourmaline, a natural ore material, was applied to the entire eyeglasses to observe changes in intraocular pressure (IOP), one of the factors related to human ocular metabolism. Methods : After making eyeglass frames by mixing TR-90, which is the main material of eyeglass frames and 7wt% of tourmaline, The changes of intraocular pressure before and after wearing of tourmaline spectacle frames were divided into low, middle and high groups according to the intraocular pressure in 90 normal subjects (46 men and 44 women) in their 20s. Results : Total intraocular pressure was a significantly decreased to -4.14% (p<0.000) in the right eye after wearing tourmaline frames, and significantly decreased to -6.39 % (p<0.000) and -4.64 % (p<0.017) in the High and Middle groups, respectively. Total intraocular pressure was a significantly decreased to -2.74 % (p<0.004) in the left eye, and -4.58 % (p<0.000) in the High group only showed statically significant value. Conclusion : In this study, the spectacle frame containing 7wt% tourmaline was used and it was confirmed that the intraocular pressure was significantly decreased after wearing the spectacle frame, and it became close to the average value of the normal intraocular pressure range. The results of this study showed that tourmaline, which has the effect of promoting the metabolism and blood circulation of the body, has an effect on the normalization of the intraocular pressure by attaching it to the spectacle frame.
Under the principle of subsidiarity, the German family policy formed in the 1950s and 1960s minimized the role of the state while maximizing the role of the parents. The German Constitutional Court, however, ruled that the level of compensation for the financial burden of child support costs must follow the basic rights, not the principle of subsidiarity. The Federal Constitutional Court has taken the duty of protecting the human dignity of the state under Article 1 of the Constitution as the starting point of the judgment. The Federal Constitutional Court held that the dignity of a child is guaranteed only if the level of the child's allowance or deduction is equal to or higher than the level of the child standard benefit under the Social Assistance Act established by Congress. The Federal Constitutional Court also regarded the state to compensate parents for child support costs as much as the level of child standard benefit under the Social Assistance Act as a family protection obligation of the state under Article 6, Section 1 of the Constitution. In addition, the Federal Constitutional Court ruled that the right to equality declared by Article 3 of the Constitution can be realized by compensating all parents for child support costs at the level of child standard benefit under the Social Assistance Act.
Korean society is now in the 2017 system. The zeitgeist is now hoping to move into a society where the right to pursue happiness centered on democracy, human rights, and peace is recognized, and to the era of the fourth industrial revolution. The paradigm shifts in the education arena began before the start of this socio-political system. The educational autonomy centered on the progressive education superintendent is accelerating the influx of alternative education, which is part of the civic education movement, through public school reforms. It can be seen that not only the progressive camp but also the conservative government emphasized educational policies such as the liberal semester system, which was gradually adopted by the government. For education that is appropriate for a rapidly changing society, it is necessary to discuss about educational grand-discourse that can alternate current public education. Although it does not mean only one discourse, it is a necessary process to systematically consider alternate education of public education and to suggest the direction for future education. In this regard, this study aims to introduce the discourse that can produce critical consciousness and creativity that emphasize the praxis and practice through critical pedagogy and bricolage.

A splint is one of assisting devices for the disabled with hemiplegia or contracture and is manually made by an experienced expert. Heated thermoplastic materials are continuously fitted to the affected part. This traditional method has a possible risk of low-temperature burn, quality variance of the splint due to the proficiency of maker. etc. While various approaches has been made using 3D printing technology in order to redeem those disadvantages, they still carry high cost issues with 3D scanners or accuracy issues with manual measurement. This research begins with symmetrical characteristics of human body and focuses on the preliminary study for the possibility of splint manufacturing with 3D printing technology based on geometric characteristics of unaffected arm. 3D right and left forearm models of healthy male adults were created by photogrammetry software and a series of digital images in order to measure the circumference and cross-sectional area of the forearm models at every 20mm from the elbow. The circumference and cross-sectional area showed tolerable levels of differences between both sides within subjects; The circumference and cross-sectional area showed very strong correlations between both sides within subjects. From these findings, the possibility of splint manufacturing with 3D printing technology could be confirmed based on the geometric characteristics of unaffected side.
This Study is to propose the archival description in accordance with the paradigm shift of the archival science. The academic world of archival science in North America treated the electric record in 1990 and the authenticity of electric record in the beginning of 2000, the flow of Study recognizing the microscopic and the cultural discussion appeared recently. This may be called the paradigm shift of archival science. This may be according to the influence of the informatization and the technology. However, the community archives, the everyday life archives recognizing the microscopic and the cultural discussion, etc. Namely, the everyday life, the village, the community archives are the effort to leave the excluded and the neglected voices from the existing discussion of archival science on record. However, the currently existing methodology to archive the community archives based on the perception of these switched recognition is limited. Especially the description of the various standards being used in the public territory is being adapted as it is. The characteristic and the individuality of the community and the community archive cannot be reflected through the archival description standard. We should understand the community archive in accordance with the paradigm shift, need the archival description method capable of expressing this suitably. The post-standard not the existing archival description method has been necessary. This should be carried out together in accordance with the view point of the paradigm shift and the view point of the objective and the direction of community. Hence, first the archival description and the paradigm shift have been examined theoretically and the archival description of community archive being operated currently has been analyzed. The archival description is to be proposed in accordance with the paradigm shift capable of calling 'the archival description of Korean Human Right' by pointing out the limit of archival description standard through the analysis and further by investigating the archival description of the fraternity archive project.
