덕후 기질이 브랜드 태도에 미치는 영향: 지역적 거리 차별에 따른 노력투여의 조절 효과 중심으로

자신이 좋아하는 것에 대해 깊이 있는 지식을 갖추고, 대상에 대한 자신의 취미를 자랑스레 여기며 사회・문화적인 교류에 적극적으로 참여하는 ‘덕후’가 중요한 소비집단으로 떠오르고 있다. 과거 연구들은 덕후들이 좋아하는 제품이나 브랜드에 대해 강한긍정적인 태도를 가진다는 것을 밝혀왔다. 이를 발전시켜 본 연구에서는 덕후들의 덕질과 구매과정 중 노력수준 그리고 브랜드태도와의 관계를 조사하였다. 본 연구의 의의는덕후들의 덕질이 구매과정의 노력수준에 따라 브랜드태도인 재구매의도와 구전의도에영향을 미친다는 것을 발견했다는 점이다. 즉 덕후들은 자신이 노력할수록, 구매과정이어려울수록 재구매의도와 구전의도에 긍정적인 태도를 가진다는 점이다. 본 논문의 결과는 덕후들을 대상으로 하는 기업들의 마케팅 전략 수립에 도움이 될 것이다.

In this study, nitrogen ions were implanted into STS 316L austenitic stainless steel by plasma immersion ion implantation (PIII) to improve the corrosion resistance. The implantation of nitrogen ions was performed with bias voltages of -5, -10, -15, and -20 kV. The implantation time was 240 min and the implantation temperature was kept at room temperature. With nitrogen implantation, the corrosion resistance of 316 L improved in comparison with that of the bare steel. The effects of nitrogen ion implantation on the electrochemical corrosion behavior of the specimen were investigated by the potentiodynamic polarization test, which was conducted in a 0.5 M $H_2SO_4$ solution at $70^{\circ}C$. The phase evolution and texture caused by the nitrogen ion implantation were analyzed by an X-ray diffractometer. It was demonstrated that the samples implanted at lower bias voltages, i.e., 5 kV and 10 kV, showed an expanded austenite phase, ${\gamma}_N$, and strong (111) texture morphology. Those samples exhibited a better corrosion resistance.

To fabricate porous SiC-Si composites for heating element applications, both SiC powders and Si powders were mixed and sintered together. The properties of the sintered SiC-Si body were investigated as a function of SiC particle size and/or Si particle contents from 10 wt% to 40 wt%, respectively. Porous SiC-Si composites were fabricated by Si bonded reaction at a sintering temperature of $1650^{\circ}C$ for 80 min. The microstructure and phase analysis of SiC-Si composites that depend on Si particle contents were characterized using scanning electron microscope and X-ray diffraction. The electrical resistivity of SiC-Si composites was also evaluated using a 4-point probe resistivity method. The electrical resistivity of the sintered SiC-Si body sharply decreased as the amount of Si addition increased. We found that the electrical resistivity of porous SiC-Si composites is closely related to the amount of Si added and at least 20 wt% Si are needed in order to apply the SiCSi composites to the heating element.

The authentication of Sokdan, one of the Korean traditional medicines, was performed with comparative study of morphological feature between Dipsaci Radix, roots of Dipsacus asper Wall. ex C.B. Clarke, and Phlomidis Radix, those of Phlomis umbrosa Turcz. In addition to a sensory observation, a stereoscope was used for more improve the accuracies. The surface of Dipsaci Rdix (DR) had more deeper furrows than it of Phlomidis Radix (PR). And more, the surface patterns of PR were more regular and fine than those of DR. In a section, DR did not have a clear distinction between nearby xylem, but PR did. In a distal section of DR, the color of cortex was dark-brown or dark- green and xylem was lemon yellow. On the other hand, PR was generally lemon yellow. It was discriminable for two herbs by observing pattern of furrows and colors of section.

In our search for medicinal herbs, a total of 35 plants were investigated in Seonyu-do, Munyeo-do, Jangja-do and Daejang-do. Among the identified plants, 10 plants in ⟪The Korean Pharmacopoeia⟫, 16 plants in ⟪The Korean Herbal Pharmacopoeia⟫, 15 plants in ⟪Pharmacopoeia of the People’s Republic of China⟫, 6 plants in ⟪The Japanese Pharmacopoeia⟫, 11 plants in ⟪Taiwan Herbal Pharmacopeia⟫and 17 plants in ⟪The Pharmacopoeia of Democratic People\'s Republic of Korea⟫ were included.

Recently, Ziziphi Mauritianae Semen and Leucaenae Semen, the adulterants of Sanjoin (Ziziphi Spinosae Semen), were distributed in korean herbal markets, although they should not be used as Sanjoin. Therefore, it is necessary to provide a accurate criteria of identification for Sanjoin and the adulterants. For authentication of Sanjoin, morphological characteristics of Sanjoin and the adulterants were compared by a stereoscopic observation. Ziziphi Spinosae Semen showed fine wrinkles on the surface without any patterns, while Ziziphi Mauritianae Semen showed the patterns like leopard skins on the surface. In addition, the shapes of transverse sections of Ziziphi Spinosae Semen and Ziziphi Mauritianae Semen were convex, while that of Leucaenae Semen was flat. These results indicate that the shapes of transverse sections and the characteristic patterns on the surfaces could be the authentic points of discrimination of Sanjoin and the adulterants.

This study was aimed to study medicinal actions of Ephedrae Herba (EH) through actions (效能) and indications (主治) in literature. A hundred or so classics from Qin-Han to Qing dynasty were mentioned in the books and a journal about the lineage of herbology. To select collectible literature in the country, we searched the national library, the national assembly library, central libraries of Wonkwang and Kyunghee university and private collections. Finally, 42 classics were selected as references. In Qin-Han dynasty, EH was recognized to have a diaphoretic and cold-dispersing effect (發汗散寒), and used for the dual disease of the exterior and interior. In Tang-Song dynasty, diseases having pathomechanism of cold-damage were noted in the indication as ever, also medical and nonmedical parts of EH were distinct from each other. In Jin-Yuan dynasty, the actions; diaphoretic action to release the exterior and calming panting action by diffusing the lung, were linked with the meridian tropism, qi and flavor, and the shape of herb to give an account of medicinal actions. In Ming dynasty, the indication was clarified to the exterior syndrome and included edema, while the dispersing action was explained by pungent flavor. In Qing dynasty, the diaphoretic mechanism was suggested as similar as the pharmacological action related to a sympathetic system. Also, diuretic action of EH in formulas was deeper understood. EH has been a sweat-promoting, panting-calming, and water-draining herbal medicine and since Ming dynasty, pungent-bitter flavor (辛苦味) was related with medicinal actions and indications of EH.

To clearly analyze the pharmacological actions of Moutan Radicis Cortex (MRC), we carried out literature review. We selected major herbal books of Qin (秦), Han (漢), Tang (唐), Song (宋), Jin (金), Yuan (元), Ming (明) and Qing (淸) dynasty, and analyzed the efficacy and the main treatments. In Qin and Han Dynasty, MRC was used to disperse blood stasis without application of the deficiency (虛) and excess (實). In Tang-Song Dynasty, although the range of application was expanded but application of the deficiency (虛) and excess (實) was the same as previous dynasty. By the Jin-Yuan Dynasty, the deficiency and excess were applicated but its pharmacological actions was not cleary established. Widely recognized mechanism of MRC for removing pathogenic heat from the blood (凉血) and dispersing blood stasis (散瘀) nowadays was deeply discussed from the Ming Dynasty and established in the Qing Dynasty.
