제품 디자인의 심리사회적 의미 연구

이주원,성영신,조경진 한국소비자·광고심리학회 2010 한국심리학회지 소비자·광고 Vol.11 No.1

The purpose of this study is to examine the psychological meaning of product design. Consumers' subjective experiences were collected by qualitative methods such as in-depth interviews. Analyzing their verbal protocol and classifying them through interpretive analysis showed that the product design has an aesthetic meaning as well as various psychological and social meanings to consumers. The results show four aspects of the design: functional meaning, aesthetic meaning, psychological meaning, and social meaning. First, consumers focus on products depending on the design which forms the first impression. Using the information derived from the design of the product, consumers presume the contents and quality of the product. Second, they enjoy looking at the design itself and tend to possess and appreciate it like other artworks. Third, the design forms the identification of the consumer whom owns the product. Consuming product designs is a way to express one's thoughts. It also provides psychological stability similar to which generated by social intercourse. Last, the design is a way to express one's self image to the society. It helps form sympathy among the people who lives the same age. Owning a product with great design can make that person socially superior then others. This study has extended the domain of consumer psychology by examining the depth of consumer experience which concerns product designs. Also, designers and marketers will be able to apply the results of this study. 본 연구에서는 제품의 디자인(product design)이 소비자에게 어떤 의미인지를 알아보기 위해 심층면접(in-depth interview)을 실시하였다. 그 결과 제품의 디자인이 소비자에게 단순히 미적 역할 뿐만 아니라 다양한 심리사회적 의미를 가진다는 것을 확인할 수 있었다. 디자인의 의미는 구매적 의미, 심미적 의미, 심리적 의미, 사회적 의미로 나누어 볼 수 있다. 첫째, 사람들은 제품의 디자인을 통해 제품에 주의를 기울이고, 디자인을 하나의 정보로 이용해 제품에 대한 첫인상을 형성하며, 제품의 내용과 질을 예상한다. 또한 실제로 디자인이 좋은 제품이 사용하기에도 편하다고 생각한다. 둘째, 사람들은 제품의 디자인을 보는 것 자체를 즐기고 그림을 감상하듯 소장하여 늘 감상하길 원한다. 셋째, 디자인은 자기 자신을 제품과 동일시하게 하고 자기표현의 수단이 되며, 마치 친구처럼 정서적 안정감을 주는 심리적 의미를 가진다. 마지막으로, 디자인은 사회적 자기 이미지를 표현하는 하나의 수단이 되고 한 시대를 살아가는 사람들 속에서 공감대를 형성하게 해주며, 사회적으로 자신을 좀 더 우월하게 만들어 주는 의미를 가진다는 것을 밝혀냈다. 본 연구는 소비자의 심층적인 심리를 끌어내어 소비자 관점에서 제품의 디자인을 이해하였다는 데에 그 의의가 있다. 이는 디자이너와 마케터들의 디자인 경영과 광고 전략에도 활용 가능할 것이다.

As elaborate attack methods on cyber-physical systems have been developed which utilize knowledge of model and control design parameters, research on securing such information using homomorphic encryption has recently been conducted. Homomorphic encryption enables direct operation on encrypted data that leads to the notion of encrypting the controller itself. Although there has been significant progress on encrypting linear controllers, the encryption of nonlinear controllers still remains challenging. This is due to the fact that homomorphic operation is either addition or multiplication and is limited to finite time horizon. In this paper, the design procedure for encrypting nonlinear controllers using the idea of feedback linearization is presented.

Effect of Guibi-tang on Neuronal Apoptosis and Cognitive Impairment Induced by Beta Amyloid in Mice

이주원,조동국,조우성,안형규,이현준,신정원,손낙원 대한한의학회 2014 대한한의학회지 Vol.35 No.4

Objectives: This study evaluated the effects of Guibi-tang (GBT) on neuronal apoptosis and cognitive impairment induced by beta amyloid (Aβ), (1-42) injection in the hippocampus of ICR mice. Methods: Aβ (1-42) was injected unilaterally into the lateral ventricle using a Hamilton syringe and micropump (2 ㎍/3 ㎕, 0.6 ㎕/min). Water extract of GBT was administered orally once a day (500 mg/kg) for 3 weeks after the Aβ (1-42) injection. Acquisition of learning and retention of memory were tested using the Morris water maze. Neuronal damage and Aβ accumulation in the hippocampus was observed using cresyl violet and Congo red staining. The anti-apoptotic effect of GBT was evaluated using TUNEL labeling in the hippocampus. Results: GBT significantly shortened the escape latencies during acquisition training trials. GBT significantly increased the number of target headings to the platform site, the swimming time spent in the target quadrant, and significantly shortened the time for the 1st target heading during the retention test trial. GBT significantly attenuated the reduction in thickness and number of CA1 neurons, and Aβ accumulation in the hippocampus produced by Aβ (1-42) injection. GBT significantly reduced the number of TUNEL-labeled neurons in the hippocampus. Conclusion: These results suggest that GBT improved cognitive impairment by reducing neuronal apoptosis and Aβ accumulation in the hippocampus. GBT may be a beneficial herbal formulation in treating cognitive impairment including Alzheimer’s disease.

본 연구에서는 뇌졸중 초기증상의 분석으로 뇌졸중 진단을 웹상에서 간단하고 편리하게 제공하고 일반인들의 뇌졸중에 대한 지식향상으로 뇌졸중을 사전에 예방할 수 있는 뇌졸중 진단 전문가 시스템 서버를 개발하였다. 또한 신경학을 전공하는 의대생들에게도 새로운 학습용 진단 시뮬레이터를 제공하도록 하였다. 전문가 시스템의 구현 방법은 여러 가지가 있으나 본 연구에서는 인공 신경회로망과, ASP(active server page)라는 웹 프로그래밍을 이용하여 뇌졸중 진단 전문가 시스템의 추론 엔진과 서버를 설계하였다. An expert system for stroke diagnosis was designed in this study. The causes of stroke in the central nervous systems are very diverse, symptoms may not appear in the early stage, so diagnosis ran be difficult. Also, doctors who treats patients with stroke must have expert knowledge for the quick and correct impending diagnosis. Therefore, an expert system for assisting the impending diagnosis of stroke has needed to be developed. In addition, the diagnosis system can be used as an simulator for medical students who study neurology. In this study, and diagnosis expert system was developed. It serves a pathological data bus provided by an interface. An inference engine makes an impending diagnosis of stroke possible. We implemented the system using Windows2000 Server, IIS5.0 and ASP.

ATP bioluminescence method is recommended to be one of simple and rapid analysis techniques for microbial monitoring. The purpose of this study was to evaluate the performance of ATP bioluminescence method for microbial monitoring and disinfection inactivation. Two different commercial ATP bioluminescence assays were compared with heterotropic plate counts(HPC) method for microbial in rainwater tank. For disinfection performance evaluation, experiments were carried out using E.coli culture. ATP bioluminescence assay and HPC method showed a significant correlation. These results showed that ATP bioluminescence gives more reliable tool for microbial monitoring. But, there are no clear correlation between inactivation of disinfection(UV, chlorination) and ATP content of the cells.
