The purpose of this study is to investigate eye fatigue and analyze symptoms of visual discomfort according to near work in young adults. A survey was conducted on 347 young adults aged 25.37 years (142 male and 205 female participants). The eye fatigue using Conlon questionnaire were surveyed and near work was investigated amounts of daily computer and smartphone. The score of eye fatigue was $13.65{\pm}7.11$ in less than 2 h/d, $16.83{\pm}6.77$ in 2~4 h/d, $18.88{\pm}6.60$ in 4~6 h/d, and $18.83{\pm}5.62$ in more than 6 hours(p=0.001). Also, headache(p<0.030), re-reading(p<0.036), and movement and fading(p<0.001) symptoms increased according to amounts of near work.

This study was performed in order to identify nutritional factors affecting on skin sebum content with 131 female university undergraduates in 2003. We measured the sebum contents of 4 facial spots to classify their skin types. Daily energy and nutrient intakes of the subjects were not deficient except in calcium and iron, which were 466.2 mg (66.6% RDA) and 8.5 mg (53.4% RDA) relatively. We observed no significant difference of energy and nutrient intakes among the 3 skin types. But significantly higher consumption of grains and slightly higher frequencies of several food groups (excepting starches) were shown in oily skin types, so they might have higher nutrient intakes. Serum indices and food preferences mostly revealed no difference among the 3 skin types. But in the oily skin type, serum phosphorus levels were significantly lower than others, suggesting phosphorus-rich food consumption like soft drinks and pains could lead to a dry skin type rather than an oily one. Also in the oily skin type, sweet taste preference was slightly tower than others; more-over, sweet intake was lower samely significantly. There was mostly no significant relationship between facial sebum contents and nutrient intakes, dietary behavior, food frequency and food preference except in some factors. Animal protein intake showed a significant negative relationship toward facial sebum content. On the other hand, in normal skin type, Fishes consumed was slightly higher than others, so that higher animal protein consumption presumably leads to normal skin type. Frequency of fried food and bacon and preference of fried foods showed slightly negative relationships toward facial sebum content. Regular meal times showed significantly increased facial sebum content.

Oxygen is an essential element for human beings' physical and mental activities, and in particular, plays an important role in brain functions. The present study attempted to investigate the effects of supply of highly concentrated (30%) oxygen on human ability of visuospatial cognition, compared to air of normal oxygen concentration (21%). This study sampled eight male university students (the average age: 23.5) as subjects. An equipment that supplies 21% and 30% oxygen at a constant rate of 8L/min was developed. Two types of questionnaire containing 20 questions were developed to measure the ability of visuospatial cognition, and accuracy and reaction time were calculated from the result of task performance. The average accuracy was $50.63{\pm}8.63$ [%] and $62.50{\pm}9.64$[%] for 21%and 30% oxygen respectively, and a statistically significant difference was found in the accuracy between the two types of oxygen. The average reaction time was $6.60{\pm}O.77$ [sec] and $7.23{\pm}0.69$ [sec] for 21%and 30% oxygen respectively, and a statistically significant difference was not found in the reaction time. The results showed that there is no difference in the average reaction time but the average accuracy rises with the supply of highly concentrated (30%) oxygen, indicating that the supply of highly concentrated oxygen has a partially positive effect on the ability of visuospatial cognition.

Objectives : Increasing evidence suggests the presence of neurobiological bases for temperamental characteristics in humans. Brain correlates of harm avoidance(HA) have been most extensively studied using functional and structural brain imaging methods due to its potential link with anxiety and depressive disorders. To date, however, we are not aware of any reports that have examined the potential relationship between HA levels and regional cortical thickness. The aim of the current study is to examine the cortical thickness which is associated with HA temperament in healthy young subjects. Methods : Twenty-eight young, healthy individuals(13 men and 15 women, mean age, $29.4{\pm}6.3$ years) were screened for eligibility and administered the Korean version of the Cloninger's Temperament and Character Inventory and underwent high-resolution structural magnetic resonance imaging scanning. Results : HA was associated with cortical thickness in the right superior frontal cortex and in the left parietal cortex, adjusted for age and sex and corrected for multiple comparisons using the permutation testing method. Conclusion : Individual temperamental differences in HA are associated with structural variations in specific areas of the brain. The fact that these brain regions are involved in top-down modulations of subcortical fear reactions adds functional significance to current findings.

Internet-only bank is one of the promising areas of Fintech industry. Kbank and Kakaobank launched services since 2017 in Korea. Experts estimated the younger generation including undergraduate students as target customers in the initial stage of the Internet-only bank in Korea. Thus, it is necessary to investigate factors influencing intention to use the Internet-only bank. Data were collected from undergraduate students studying in Seoul, Pusan, and Gyeongbuk province. The empirical study showed the evidence that four factors such as convenience, social influence, perceived privacy, and unverified risk had a significant influence on intention to use the Internet-only bank. However, economic benefit has no significantly influence on the intention. The present study focused on the influence of convenience and social influence and discussed the issues regarding convenience and social influence in more detail.

What has been rapidly changed and developed is not only technology, but also language and culture, of which the diverse consensus has been speedily formed between generations and spread throughout all the social grades. Therefore, Neologisms need to be understood as part of the cultural history that is created at each period. We cannot keep neologisms, initially formed among the youths, from spreading all over the generations, not just for their enjoyment, convenience, and familiarity, but more for the fact that they are impossible to be replaced in use. Another reason is that a community is created according to language. The youths would like to make distance from the existing community by building an invisible wall of new language. This paper is intended to deal with neologisms, centered on visual pun. The characteristics of the Neologisms are the result of the tendency of the younger generation to avoid interference and to enjoy adding ingenuity to the existing order.That is why in all ages Neologisms are created, and although they differ in form, the principles of new word generation are old. We will also consider the historical characteristics of neologism in this paper.

Purpose: Kimura's disease is an uncommon benign lymphoproliferative inflammatory disorder with an unknown etiology. The recurrence rate after surgical excision is relatively high and renal involvement is its only systemic manifestation. The condition mainly involves the head and neck, and peripheral involvement is extremely rare. Materials and Methods: We encountered the case of a 28-year-old man who had a non-tender mass with mild brownish skin color changes and pruritus around the medial side of the distal arm and elbow. Results: The peripheral blood investigation revealed peripheral eosinophilia and elevated serum IgE levels. Magnetic resonance imaging showed an isointensity signal relative to the muscle on the T1-weighted images and hyperintensity signal relative to the muscle on the T2-weighted images. Conclusion: A marginal resection of the lesion was performed and there was no recurrence at 2 years postoperatively.

A 'Readymade' is an everyday object selected and designated as art. The term was coined by Marcel Duchamp to describe his artistic process based on the attempt to destroy the notion of the uniqueness of the art object: his influence went for beyond the art world affecting all design activities based on creativity. The purpose of this study is to investigate the ready-made technique from an educational point of view. Starting from Duchamp experience and his further influence on the design world, the study aims to demonstrate the value of the ready-made technique as a basic element in the education of young designers. The research method is based on the empirical observation of the results of the same project assigned to forty different students in different universities. The collected results were grouped in four families according to each specific generative method: constructive, conceptual, aggregative and elaborative. These four categories, derived by the observation of the results, represent tangible variations of the same disciplined technique. This flexibility demonstrates the value of the ready-made process as a foundation practice particularly indicated for young designers. These are the main skills students developed through its application to design projects; exploring and reconsidering attitude, recycling issues, new identity to familiar objects, focus on ideas.

The purpose of this study was to analyze the gait characteristics and interaction between lower extremity joints according to shoe's heel heights in young women. Participants were selected as subject consisted of young and healthy women (age: $23.71{\pm}1.49yrs$, height: $165.92{\pm}2.00cm$, body weight: $54.37{\pm}3.46kg$) and walked with 3 types of shoe's high-heel (0, 5, 9 cm). The variables analyzed consisted of the displacement of Y axis in center of mass ([COM]; (position, velocity), front rear(FR) and left right(LR) angle of trunk, lower extremity joint angle (hip, knee, ankle) and asymmetric index (AI%). The displacement of Y axis in COM position showed the greater movement according to increase of shoe's heel heights, but velocity of COM showed the decrease according to increase of shoe's heel heights during gait. The hip and knee angle didn't show significant difference statistically according to increase of shoe's heel height, but left hip and knee showed more extended posture than those of right hip and knee angle. Also ankle angle didn't show significant difference statistically, but 9 cm heel showed more plantarflexion than those of 5 cm and 0 cm. The asymmetric index (AI%) showed more asymmetric 9 cm heel than those of 0 cm and 5 cm. The FR and LR angle in trunk tilting didn't show significant difference statistically according to the increase of shoe's heel height during gait in young women.
