1인 가구의 쇼루밍 이용 속성, 쇼루밍 태도와 지속적 쇼루밍 의도의 관계

정성광,차경천 한국마케팅학회 2020 마케팅연구 Vol.35 No.3

Multi-channel consumer is defined as a consumer who solves by using various channels rather than a single channel in the purchasing decision process for products. An example of multi-channel choice behavior is show-rooming. The Show-rooming tribe use online distribution channels to purchase products after looking at products in offline stores. This show-rooming phenomenon is taking place more actively through the development of the Internet environment and smart phones and the changes in the life cycle stage such as single-person households. This study used Expectation-Confirmation Model(Bhattacherjee 2001) for show-rooming usage attributes. The effect of show-rooming usage attributes (expectation confirmation, perceived usefulness) on show-rooming attitude (cognitive, emotional) and continuance show-rooming intention was analyzed. In addition, it was analyzed whether the influence of show-rooming use attributes on show-rooming attitude depends on single-person household. Structural equation model was used for data analysis, and the main results are as follows. First, we found that show-rooming usage attributes (expectation confirmation, perceived usefulness) had the significant and positive effect on show-rooming attitude (cognitive, emotional). Second, we found that show-rooming attitude (cognitive, emotional) had the significant and positive effect on continuance show-rooming intention. Third, the impact of show-rooming usage attributes (expectation satisfaction, perceived usefulness) on show-rooming attitude (cognitive, emotional) was more positive in single- person households. Therefore, for making the positive attitude of using show-rooming, it is necessary to strengthen the development of marketing strategies for offline and online stores considering single- person household. 멀티채널 소비자란 제품 구매의사결정과정에서 단일 채널이 아닌 다양한 채널을 이용하여 해결하는 소비자를 의 미한다. 멀티채널 소비자의 경우 오프라인 매장에서 제품을 살펴본 후 실질적인 구매는 온라인 유통 채널을 활용 하는 쇼루밍족이 대표적이다. 이러한 쇼루밍 현상은 인터넷, 스마트폰의 발달과 1인 가구 등과 같은 인구구조의 변화를 통해 더욱 활발히 일어나고 있다. 본 연구는 쇼루밍 이용속성에 대해 Bhattacherjee(2001)의 기대충족이론을 활용하여, 쇼루밍 이용속성(기 대충족, 지각된 유용성)이 쇼루밍 태도(인지적, 정서적)와 지속적 쇼루밍 의도에 미치는 영향을 분석하였다. 이 와 함께 쇼루밍 이용속성(기대충족, 지각된 유용성)이 쇼루밍 태도(인지적, 정서적)에 미치는 영향은 1인 가구 여부에 따라 어떻게 달라지는지 분석하였다. 자료분석은 구조방정식모형을 활용하였으며, 주요결과는 다음과 같다. 첫째, 쇼루밍 이용 속성(기대충족, 지각 된 유용성)은 쇼루밍 태도(인지적, 정서적)에 긍정적인 영향을 유의하게 미치는 것으로 나타났다. 둘째, 쇼루밍 태도(인지적, 정서적)는 지속적 쇼루밍 의도에 긍정적인 영향을 유의하게 미치는 것으로 나타났다. 셋째, 쇼루밍 이용 속성(기대충족, 지각된 유용성)이 쇼루밍 태도(인지적, 정서적)에 미치는 영향은 1인 가구의 경우 더 긍정 적인으로 나타났다. 따라서 쇼루밍 이용 태도 형성의 경우 1인 가구의 영향을 고려한 오프라인, 온라인 매장의 마케팅 전략 개발을 강화할 필요가 있을 것이다.

주관적 지식에 따른 홈 인테리어 서비스 체험 요소와 몰입 및 브랜드 애호도의 관계

정성광,정성진,차경천 한국마케팅관리학회 2019 마케팅관리연구 Vol.24 No.1

오늘날 소비자들은 매장에서의 제품을 통해 공간 인테리어에 대한 아이디어 형성에 도움을 얻고 구매를 하기 때문에 홈 인테리어 서비스 제공기업에 있어서 체험 마케팅은 매우 중요하다고 할 수 있다. 제품의 실용과 편익에 의한 소비 못지않게 제품이 제공하는 상징과 쾌락에 의한 소비가 증가하고 있다. 이에 각 브랜드들은 실용적 뿐 아니라 상징적, 쾌락적 포지션 확보를 위해 브랜드 체험을 통한 마케팅 커뮤니케이션을 지속적으로 실시하고 있다. 따라서 본 연구는 보다 효과적인 홈 인테리어 서비스 전략을 위해 Schmitt(1999)가 주장한 서비스 체험 요소를 감각적, 감성적, 인지적, 행동적, 관계적 체험으로 구분하였으며, 이에 따른 몰입과 브랜드 애호도에 미치는 효과를 분석하였다. 또한 서비스 체험 요소(감각적, 감성적, 인지적, 행동적, 관계적)와 몰입 및 브랜드 애호도의 관계에서 소비자 주관적 지식의 조절적 역할을 검증하였다. 한편 실증분석은 SUR을 통하여 실시하였으며, 결과는 다음과 같다 첫째, 홈 인테리어 서비스 체험 요소 중 감각, 감성, 인지, 행동, 관계적 체험은 홈 인테리어 서비스 몰입에 긍정적 영향을 미쳤다. 둘째, 홈 인테리어 서비스 몰입은 브랜드 애호도에 대해 긍정적인 영향을 미쳤다. 셋째, 주관적 지식의 조절효과는 홈 인테리어 서비스 체험 요소 중 감각적 체험에는 부의 영향을, 인지적 체험에는 정의 효과를 보였다. 이에 대한 연구결과를 바탕으로 실무적, 이론적 시사점 및 연구의 한계점, 향후 연구방향에 대하여 제시하였다. Today, experiential marketing is very important for home interior service companies. Because consumers get and purchase interior ideas through products of store. Therefore, consumers are increasingly consuming the pleasures offered by the products as well as the function and benefit of the products. So, each brand should implement not only position of utilitarian but also marketing communication through brand experience in order to position of hedonic. In this study, we analyzed the impacts of sense, feel, think, act and relate experience as attributes of home interior service claimed by Schmitt(1999) for studying home interior service industry on flow and customer loyalty. In addition, we will examine the control effect of consumer’s subjective knowledge with home interior service experience attributes and flow. In order to achieve the purpose of the study, this study data collection was conducted for actual consumers who had experience using the home interior service. Finally, the data of 268 respondents was used for this study. The empirical analysis of this study was conducted through SUR, and the results are as follows. First, sense, feel, think, act and relate experience among the experience factors of home interior service have a significant and positive impacts on the flow of home interior service. Second, it can be seen that the flow of the home interior service positively affects the brand loyalty. Third, it can be seen that the influence of sense, think in the home interior service depends on consumer’s subjective knowledge. Based on the research findings, the study offered practical and theoretical implications, limits of this research and directions for further research.

반복된 급성 신부전을 동반한 IgA 신병증 1례

정성광,류재춘,정광호,노승현,고행일 인제대학교 1994 仁濟醫學 Vol.15 No.4

IgA 신병증(IgA nephropathy)은 신장의 메산지움에 IgA가 침착하는 질병으로 사구체 기원의 재발성 혈뇨의 가장 흔한 증상이다. 상당수의 환자에서 진단 후 상당한 시일이 지난뒤 만성 신부전으로 진행하지만 드물게는 급성 신부전으로 발현하여 저절로 회복되기도 한다. 저자 등은 반복된 급성신부전으로 발현한 IgA 신병증 1례를 경험하였기에 문헌고찰과 함께 보고한다. During the course of IgA nephropathy self limited and reversible form of acute renal failure may occur, which is often accompanied by episode of massive gross hematuria and frequently preceded by an upper respiratory tract infection. We experienced a 37-year old female without a history of recurrent synpharyngitic macroscopic hematuria present with severe loin pain, macroscopic hematuria and oliguric aute renal failure. Although the patient's renal biopsy showed mild to moderate glomerular change, the extent of glomerular involvement could not explain the severe acute deterioation of renal function. We think that acute tubular lesion secondary to severe glomerular bleeding seemed to play a significant role in the pathogenesis of recurrent deterioration of renal function. We present this case with review of literatures.

Spontaneously Hypertensive Rat에 있어서 Renin-Angiotensin계의 변조에 관하여

정성광,조경우,Chung, Sung K.,Cho, Kyung W. 대한생리학회 1985 대한생리학회지 Vol.19 No.2

Enhanced activity of renin-angiotensin-aldosterone system has been suggested as a cause of the high blood pressure in certain forms of experimental hypertension. In spontaneously hypertensive rats, however, increased activity of the system has not been found, and even suppressed renin angiotensin system has been reported in the spontaneously hypertensive rat. In the present experiments it was attempted to explore the possible alteration of the short loop negative feedback control in the hypertensive rat. Experiments have been done in the anesthetized spontaneously hypertensive rats(SHR) as well as in normotensive Wistar and Sprague Dawley rats as control. Responses of the plasma renin activity to the intravenous L-isoproterenol were dose dependent, in both SHR and normotensive control rats. Hypotensive responses to smaller do sea of L-isoproterenol were more accentuated in SHR than in the normotensive control rats. Angiotensin If given intravenously suppressed plasma renin activity in a dose dependent fashion in both groups. However, these suppressive responses were significantly attenuated in SHR as compared with the normotensive control rats. Treatment with angiotensin I-converting enzyme inhibitor did not correct the attenuated responses of the plasma renin activity to angiotensin II in SHR. Intravenous infusion of arginine vasopressin also produced a dose-dependent suppression of plasma renin activity in both groups. The responses to arginine vasopressin were also significantly attenuated to the normotensive control rats. In the sodium-depleted SHR, arginine vasopressin did not suppress plasma renin activity, whereas the suppressive responses to arginine vasopressin in the normotensive control rats were not different from the untreated control rats. These data suggest that there may be a derangement in the short loop negative feedback control of the renin-angiotensin system in spontaneously hypertensive rat.

주정 중독 흰쥐에서 총담관 결찰이 간의 Mitochondria 및 Microsome의 총 Monoamine oxidase와 혈청의 Benzylamine oxidase활성에 미치는 영향

김여희,안광욱,곽춘식,정성광 啓明大學校 醫科大學 1993 계명의대학술지 Vol.12 No.1

The activities of the hepatic mitochondrial and microsomal total monoamine oxidase(MAO), and serum benzylamine oxidase were studied for cholestasis induced by common bile duct ligation and acute ethanol intoxication developed, or cholestasis after chronic ethanol intoxication for manifestation of the biochemical background of alcohol intoxication in hepatobiliary disease. There were marked increases in the mitochondrial and microsomal total MAO activities of the liver in the rats treated with chronic ethanol intoxication, and showed a significant increase in the mitochondrial total MAO after treatment with acute ethanol intoxication. When common bile duct was ligated in the rats, mitochondrial total MAO activity in the liver significantly decreased. When common bile duct was ligated after chronic ethanol intoxication and acute ethanol intoxication was done after common bile duct ligation, the activity of the mitochondrial total MAO in the liver decreased more significantly than the group only with ethanol intoxication was performed. However, the activity showed a higher degree on the same time points than the groups only with the common bile duct ligation. The serum benzylamine oxidase ectivity in the group with only common bile duct ligation or the ethanol intoxication with cholestasis were measured between the 7th and 14th day, with no difference between two groups. According to the above results, the hepatic MAO seems to be an enzyme in which its activity increases in acute and chronic ethanol intoxicaion. And total MAO in the liver is the enzyme with increased activity in ethanol intoxication with cholestasis more than in cholestasis. The cause of the increase is the development of biosynthesis. Accordingly, these results will be the data supporting that alcoholic drink is enzymologically harmful in hepatobillary disases.
