공태경,김도완 대한통증학회 2013 The Korean Journal of Pain Vol.26 No.1

Compensatory hyperhidrosis or reflex hyperhidrosis is the increase in sweating in the postoperative stage of thoracic sympathectomy or lumbar sympathectomy. It shares several features with anxiety disorders and has a negative impact on a patient’s quality of life. Oralglycopyrrolate is one of the treatment options available. This study reviewed case notes in a series of 19 patients with compensatory hyperhidrosis. We made a comparison between the Milanez de Campos score of a pre-glycopyrrolate medication group and the Milanez de Campos score of a post-glycopyrrolate medication group. The Beck Depression Inventory (BDI) score, Beck Anxiety Inventory (BAI) score, and autonomic nervous system (ANS) scale score were also compared between the pre-medication and post-medication groups. In the post-glycopyrrolate medication group, there was decrease in the Milanez de Campos score, BAI score, and BDI score (P < 0.05). But no meaningful change was seen in the ANS score in the post-glycopyrrolate medication group (P > 0.05). Glycopyrrolate is an effective medication in the treatment of compensatory hyperhidrosis that, can alleviate anxiety and improve patients’ quality of life.

공태경,문현주,김대일 한국전기전자재료학회 2016 Transactions on Electrical and Electronic Material Vol.17 No.2

ZnSnO3 (ZTO)/Ag/ ZnSnO3 (ZTO) trilayer films were prepared on glass substrates by radio frequency (RF) and direct current (DC) magnetron sputtering. The electrical resistivity and optical transmittance of he films were investigated as a function of the Ag interlayer thickness. ZTO films with a 15 nm thick Ag interlayer show the highest average visible transmittance (83.2%) in the visible range. In this study, the highest figure of merit (2.1×10-2 Ω cm) is obtained with the ZTO 50 nm/Ag 15 nm/ZTO 50 nm films. The enhanced optical and electrical properties of ZTO films with a 15 nm thick Ag interlayer are attributed to the crystallization of the Ag interlayer, as supported by the distinct XRD pattern of the Ag (111) peaks. From the observed results, higher optical and electrical performance of the ZTO film with a 15 nm thick Ag interlayer seems to make a promising alternative to conventional transparent conductive ITO films.

Recently, numerous enterprises are proceeding various promotions of donation due to the expansion of the worldwide symbiosis culture. However, it is true that there is an inadequacy of psychological mechanisms researching the consumer's donation behavior, and the collisions occurring between these theories. According to the previous studies research, it has shown that the mind of supporting the weak, which it is called the underdog effect, is affecting the consumers’ donation behavior, i.e., there is a strong increase of intention to donate where the majority yet didn't donate. On the contrary, this result has the incompatibility between the tendency to imitate what the majority have chosen, which is called the conformity effect. In the conformity effect, check the moderating variable about involvement and self-construal if the consumer has interdependent self-construal(vs. independent self-construal) under the low involvement circumstance, there was an increment of conformity. Therefore, the purpose of this research is to confirm which option has more strength between the underdog effect and the conformity effect to demonstrate the mechanism of the consumer’s donate-selection. Furthermore, it has been conducted to analyze the moderation of self-construal and the degree of involvement which can affect the acceptability. To be specific, this study has analyzed consumers donate-selection behavior by proposing a virtual scenario franchise coffee shop-conducted donation campaign for COVID-19 relief activity to 79 participants. As a result, it has revealed that the underdog effect was effective than the conformity effect. Also, this tendency has become more clear in those who have a high involvement. Yet, the moderating effect of self-construal was irrelevant to this consequence. Therefore, this study has discussed the theoretical, operational implications on the basis of the analysis result. 최근 공생의 문화가 확산되면서 다양한 기부 프로모션이 진행되고 있다. 하지만 소비자의 기부행동에 대한 심리적 매커니즘을 분석한 연구는 미흡하며, 이론간 충돌이 발생하고 있다. 기존 연구결과에 따르면 약자를 응원하는 언더독 효과(underdog effect)가소비자의 기부행동에 영향을 미치는 것으로 나타났다. 하지만 이는 소비자가 일반적으로 여러 사람들이 많이 선택한 것을 따라하려는 경향을 의미하는 동조행위(conformity) 와 상반된다. 동조효과(conformity effect)에 관한 연구에 따르면, 소비자는 관여도가낮은 상황에서 상호의존적 자아해석을 가진 경우 동조행위가 증가하는 것으로 확인되었다. 따라서 본 연구는 소비자의 기부 선택 매커니즘을 설명하는 이론 중 어떤 것이 더설득력이 있으며, 이에 영향을 줄 수 있는 관여도와 자아해석의 조절효과를 분석하려는목적을 가지고 진행되었다. 구체적으로 코로나 기부캠페인의 가상시나리오를 제시한 후소비자의 기부선택 행위를 분석하였다. 그 결과, 남들이 많이 기부하지 않은 곳에 기부하려는 언더독 효과가 소비자의 기부선택에 대한 설명력이 더 높은 것으로 나타났다. 또한 언더독 효과는 고관여인 경우 더 커지는 것으로 확인되었다. 하지만 예상과 달리자아해석의 조절효과는 유의하지 않았다. 본 연구는 이러한 분석결과를 토대로 이론적, 실무적 시사점에 대해 논의하였다.

Background: Farnesylacetone compounds that dilate blood vessels by blocking calcium channels in sargassum siliquastrum have been reported. And this study was done to demonstrate the effect of YJ-7, a synthetic material derived from these compounds,on vessel dilation and blood pressure control. Methods: We used vasoconstricted basilar and carotid artery of rabbits. Changes in blood pressure were measured in vivo at 15,30, 45, and 60 minutes after intravenous injection of YJ-7 3 μM,EC50 value from in vitro experiment, and nimodipine 10 μM through the tail vein of 20 rats. Spontaneous hypertensive rat (SHR) has its blood pressure higher than 190 mmHg. Measurements of blood pressure were done 6 times and the mean values were used for data analysis. Results: Systolic and diastolic blood pressure before the injection of YJ-7 were 194.2 ± 6.1 mmHg and 140.2 ± 6.4 mmHg. Blood pressure were decreased with time, 157.2 ± 2.6 / 120.8 ± 4.2 mmHg at 15 minutes, 161.8 ± 18.3 / 123.2 ± 13.9 mmHg at 30 minutes,and 156.0 ± 4.1 / 112.4 ± 1.7 mmHg at 45 minutes. The blood pressure lowering effect lasted until 45 minutes. However, the blood pressure increased to 182.2 ± 16.4 / 149.0 ± 20.4 mmHg at 60minutes reaching similar levels of before the injection (P < 0.05). Conclusions: We could see YJ-7 has vasorelaxation effect and would be helpful to control blood pressure with short recovery period than nimodipine.

Effect of a Cu Buffer Layer on the Structural, Optical, and Electrical Properties of IGZO/Cu bi-layered Films

문현주,공태경,김대일,최동혁,손동일 한국전기전자재료학회 2016 Transactions on Electrical and Electronic Material Vol.17 No.1

Transparent and conducting IGZO thin films were deposited by RF magnetron sputtering on thin Cu coated glass substrates to investigate the effect of a Cu buffer layer on the structural, optical, and electrical film properties. Although X-ray diffraction (XRD) analysis revealed that both the IGZO single layer and IGZO/Cu bi-layered films were in the amorphous phase, the IGZO/Cu films showed a lower resistivity of 5.7×10-4 Ωcm due to the increased mobility and high carrier concentration. The decreased optical transmittance of the IGZO/Cu films was also attributed to a one order of magnitude higher carrier concentration than the IGZO films. From the observed results, the thin Cu layer is postulated to be an effective buffer film that can enhance the opto-electrical performance of the IGZO films in transparent thin film transistors.

Effect of Brand Popularity in a Foreign Market on Consumer Behavior in a Franchise Cosmetic Retailer's Online Shop

김지헌,공태경,안소정 한국프랜차이즈경영학회 2020 프랜차이즈경영연구 Vol.11 No.2

Purpose: As consumers have difficulty in brand choice due to excessive information, using brand popularity as an advertising cue (e.g., Sales No. 1, Hit Product) has been getting more attention as an effective curation strategy for decreasing consumers’ cognitive efforts. Accordingly, recent studies empirically demonstrate that consumers tend to prefer and choose a brand with a popularity cue and offer a useful information regarding how to use a popularity cue in marketing communication. However, extant research has mainly focused on investigating the impact of “brand popularity in a domestic market” on consumer behaviors. Thus, little is known about the effect of “brand popularity in a foreign market” on local consumers’ decision-making process. Given that domestic consumers tend to purchase imported products from overseas countries, it can be meaningful information for global companies. Therefore, this research derives and tests the five hypotheses to examine how local consumers respond to brand popularity in a foreign market as an advertising cue. Specifically, it tests the three hypotheses regarding the direct and indirect effects of brand popularity in a foreign market on risk perception and purchase intention. Then, it tests two additional hypotheses about moderating effects of psychic distance on the relationship between brand popularity and risk perception as well as on the relationship between brand popularity and purchase intention. Seventy participants are exposed to an advertisement for an Indian cosmetic brand using a popularity cue in Indian market and answer the questions about brand evaluation. For data analysis, regression analysis is employed. The findings of this research show that perceived brand popularity lowers local consumers’ perceived risk with a foreign brand. However, perceived brand popularity does not have a direct impact on purchase intention while it has an indirect effect through perceived risk. Meanwhile, psychic distance moderates the effect of perceived brand popularity on perceived risk level, but it has no impact on the relationship between brand popularity and purchase intention. This research is one of the first studies that demonstrate the positive impact of brand popularity in a foreign market on a local consumer’s purchase decision, and it shows the effect can be moderated by psychic distance.
