The purpose of this study was to find out the effect of fashion information source in the stage of purchase decision-making and difference by stage of purchase decision-making and difference by stage of the effect extend, and to analyze the difference by fashion information source. For this study, the data were collected through the questionnaire distributed to 337 female students from five universities. The results are as follows: 1) There was significant difference among the effect to fashion information source according to the purchase decision-making stage. At the adoption stage, fashion information source have the most effect on clothing purchase. 2) The effect of Impersonal Source in the purchase decision-making stage was gradually decreased fro the initial (awareness, interest) sage to the late stage. 3) The effect of Personal Source in the purchase decision-making stage was gradually increased from the initial (awareness, interest) stage to the late stage. 4) Addition stage was highly influenced by friend and family that was Personal Independent Source than other fashion information source. However the final selection on clothing purchase was not influenced by friend and family. 5. There was significant difference among the effect of fashion information source according to the grade. Low garde students were highly influenced by Personal Source on clothing purchase, but high grade students were highly influenced by Impersonal Sources on clothing purchase. 6) There was significant difference among the effect of fashion information source according to the major. The students a majored clothing & textile-design were highly influenced by Impersional Source. These results suggest that fashion information source was significantly different according to purchase decision-making stage and was influenced by grade and major of subjects.

Higher yield in rice paddies is greatly dependent on adequately balanced and timely supply of water. A majority of rice paddy in Korea is generally irrigated by rainfall, but in many cases it has to be supplemented by artificial irrigation for optimum rice culture. Although the water requirement of rice plant is for higher Than that of athec crops, submerged condition of rice paddy is not Necessarily required. The moisture requirement of rice plant varies with its growing stages, and it is possible to increase the irrigation efficiency through reduction of water loss due to percolation in rice paddies. An experimental plots were set up by means of sandomized block design with three duplication; (a) All time submerged, (b) Economically controlled, and (c) Extremely controlled. Three different irrigation periods Were (a) Initial sage, (b) Inter-stage, and (c) Yast stage. The topsoil of the three plots were excavated to the depth of 30 cm and then compacted with clay of 6 cm thickness. There after, they were piled up with the excavated top soils, leveled and cored with clay of 6 cm thickness around footpath in order to prevent leakage. The results obtained from the experiments are as follows, 1. There is no difference among the three experiments plots in terms of physical and chemical conditions, soil properties, and other characteristics. 2. Culm length and ear length are not affected by different irrigation methods. 3. There is no difference in the mature rate and 1, 000 grain weight of rice for the three plots. 4. The control plot which was irrigated every three days shows an increased yield over the all the time submerged plot by 17.8 percent. 5. The clay lined plot whose water holding capacity was held 5 days long, needs only to be irrigated every 7 days. 6. The clay lined plot shows an increased yield over the untreated plot ; over all-the-time submerged plot by 18 percent ; extremely controlled plot by 18 percent, and economically controlled plot by 33 percent. 7. It may be saved in water requirement about one Thirds.

This writing, focused on by Tarkovsky and by Song, Il-gon, examines moments of sage which is what Eliade described as 'hierophanic time'. These productions, which can be seen as movies that seek after the truth, show important paradoxical ideas and expressions in those moments. This is because symbolic messages from unrealistic and out of ordinary images are specifically shown. If they had to be compared, through the film by Tarkovsky, the technical civilization of contemporary society in an apocalyptic view is criticized and saved, or the prophetic will to not give up the desire for salvation is shown. In the process, the short shots which forces to show hierophanic time not only diversely visualized the author's ideological self-consciousness towards the conversion of the new world, but it also fulfills the metahistorical meanings mentioned by Eliade. However, in the film by Song, Il-gon, the realistic personal sufferings of three women is specifically shown first in extreme. They overcome their unsolvable problems through mysterious rituals and belief in miracles. In the scenes that include hierophanic time, there are many cases that cover Christian faith and the meaning of salvation. In other words, we can say that hierophanic time in , are related to conviction which led to moments of miracles in order to overcome reality. Therefore, even though there is a difference in the way authors use hierophanic time, the scenes that show it in the two movies display individuality of mythical imaginations disclosed by Eliade. This is because the general hope for reproduction, or meaningful symbols related to the ideal conversion of affairs are revealed.

Old age is often compared as climbing mountains which requires walking out of breath, yet with wider vision. And it is also likened to the estuary where the river flows slowly and broadly into the open sea. Socially, old age has been regarded as a symbol of wisdom and reflection, and elderly people often take the role of sage who leads the community. On the other hand, the dementia, gray hair and wrinkles of old age were sometimes perceived as the decline of intellect and vitality. Especially, in the digital age in which technology makes people more sensitive to physical artificiality, the evaluation of the old age becomes more complex and obscure. In other words, some elderly people can not escape from Confucious convention of the elders first, which causes the denouncement by younger generations. On the other hand, some elderly people are becoming more adaptable to the trend of young people, emerging as the new elderly people. The anti-aging movement, early adaptation of IT, bioengineering regimen also strong for the advanced age. However, as the new elderly people are active in many fields of society, they also face intergenerational conflicts in some areas where remains the overlap between young people and them due to the limited openings in economy and culture. This study is a transdisciplinary research which can be called old age humanities. First of all, this paper looks at the aspects of lifestyles and intergeneration conflicts in old age in four Korean and Western literary works about the old people, and also searches how to improve the quality of the later life of old people, Overall, this paper aims to explore the way the old people can achieve the full life with the help of intergenerational dependency through building aging humanities and new communities for old people.

Heat treatment is an important step for tool manufacture, but unavoidably generates dimensional distortion. This study investigated the continuous dimensional change and the anisotropic behavior of STD11 tool steel during austenitizing and tempering heat treatment especially using quenching dilatometer. Dilatometric results represented that the dimensional change along longitudinal direction was larger than that along transverse direction. Anisotropic phase transformation strain was produced in forged STD11 tool steel during heat treatment. Anisotropic dimensional change increased with increasing austenitizing temperature. After tempering, anisotropic distortion was partially reduced. FactSage thermodynamic equilibrium phase simulation and microstructural observation (FE-SEM, TEM) showed that large ($7{\sim}80{\mu}m$) elongated $M_7C_3$ carbides could be formed along rolling direction. The resolution of elongated carbides during austenitizing was found to be related with the change of martensite transformation temperature after heat treatment. Anisotropic size change of STD11 tool steel was mainly attributed to large elongated carbides produced during rolling process. Using dilatometric and metallographic examination, the possible mechanism of the anisotropic size change was also discussed.

Biotin is a water-soluble vitamin used as a skin conditioning agent and promotes the formation of intercellular lipid layers through increased lipid synthesis, which improves the skin's natural barrier function. The anti-inflammatory effects of biotin have been investigated using in vitro assay models, such as MTT assay, measurements of concentrations of nitric oxide(NO), prostaglandin E2(PGE$_2$), and inhibition rate of 5-lipoxygenase(5-LOX). In comparison with biotin, other plant extracts were tested at the same time which were kudzu vine extract, sage extract, paeonia extract, and dipotassium glycyrrhetinate. Nitric oxide is a signal molecule with functions such as neurotransmission, local vascular relaxation, and anti-inflammation in many physiological and pathological processes. NO can cause apoptosis and necrosis of target cells such as keratinocytes and is generated from L-arginine by nitric oxide synthase (NOS). Prostanoids, including prostaglandins and thromboxanes, are generated by the phospholipase $A_2$/cyclooxygenase(COX) pathway, and leukotrienes are generated by the 5-lipoxygenase pathway from arachidonic acid. Prostaglandin E2 recently have been shown to be beneficial in the resolution of tissue injury and inflammation, also has been implicated as an immunosuppressive agent and plasma levels of PGE$_2$ are elevated in patients sustaining thermal injury. Lipoxygenase metabolites from arachidonic acid have been implicated in inflammation, anti-inflammatory activity of the raw materials was evaluated in vitro by the offered inhibition of lipoxygenase.

Purpose: The goal of this systematic review was to compare the use of cone-beam computed tomography (CBCT) with that of computed tomography (CT) for volumetric evaluations of the tongue and oral cavity. Materials and Methods: A search for articles was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-analyses guidelines. The PubMed, Scopus, ScienceDirect, and SAGE Journals databases were searched for articles published between 2011 and 2021. Articles were screened and assessed for eligibility. Screening involved checking for duplication, reading the title and abstract, and reading the full text. Results: The initial search retrieved 25,780 articles. Application of the eligibility criteria yielded 16 articles for qualitative analysis. Multiple uses of CBCT were identified. In several studies, researchers assessed the volumetric correlation between tongue and oral cavity volumes, as well as other parameters. Post-treatment volumetric evaluations of the oral cavity were also reported, and the reliability of CBCT was assessed. The use of CT resembled that of CBCT. Conclusion: CBCT has been used in the evaluation of tongue and oral cavity volumes to assess correlations between those volumes and with the upper airway. It has also been used for volumetric evaluation after surgical and nonsurgical procedures and to assess the relationships between tongue volume, tooth position, occlusion, and body mass index. Participants with obstructive sleep apnea and malocclusion have been evaluated, and the reliability of CBCT has been assessed. In the included studies, CT was utilized for similar purposes as CBCT, but its reliability was not assessed.

This study investigated the process of how adolescents get caught into a net of online prostitution and get out of it. An in-depth interview was done with 43 adolescents who experienced online prostitution. It was found that 38 of 43 interviewees(88%) had an experience of running away from home and that 23 adolescents(53%) among them got involved in online prostitution for living expenses. Leaving home was a major route to prostitution. Fifty six percents experienced prostitution at the ages of 16 or 17 for the first time. The age group of 13-15 took 35%, which provided an evidence that most prostitutes experienced young. Moreover, the frequency of prostitution was shocking. Those who prostituted themselves 'more than 10, but less than 50 times(40%)' were more than those who did 'less than 10 times(37%).' Those who did 'more than 100 times' or even countlessly were 21%. Violation of human rights such as perverted sex, violence, sexual violence, threat, abduction, fraud, extortion by threats, and infection of sexually transmitted disease(STD) occurred quite often. In addition, the process of adolescent online prostitution categorized into the three stages: vulnerable stage, chaotic stage, and stabilized(out-of-prostitution) stage. It was possible that the three stages moved back and forth. The process shifted from the vulnerable stage to the chaotic one, and could get back to the vulnerable one. Or the speed of moving forward to the next sage could be accelerated if the individual management skills were coupled with support from many people and institutions.
