21세기를 사는 우리에게 디자인은 더 이상 산업적 부가 가치로서 생산과 소비를 활성화하는 행위가 아니라 보다 넓은 사회적 문화적 실천행위로 인식되고 있다. 본 연구의 목적은 문화생산의 주체적 발신자로서 디자인 역할의 확대와 디자인 그 자체가 문화로서의 자족성을 가져야 함을 주장하는 것이다. 연구문제는 문화산업의 중심에는 무엇보다도 디자인 행위가 있어야 할 것이라는 가정으로부터 출발한다. 연구의 범위는 거시적으로 문화산업과 디자인 정책에 대한 문헌연구 및 현황과 사례분석, 그리고 미시적으로 한국 미국 영국이라는 3개국 디자이너의 정책인식에 대한 비교조사 및 분석으로 진행하였다. 조사의 방법은 한국 미국 영국에서 양적연구(quantitative research)로서 설문조사를 실시하였으며, 디자인 정책의 과거 사실뿐만 아니라 현재의 현상에 대해서도 설명하고자 질적연구(qualitative research)로서 심층면접(intensive interview)을 병행하였다. 설문조사는 3개국의 디자인 전문가를 대상으로 비교하였으며, 심층면접은 한국에서 의사결정권을 가진 관리자급의 디자인 전문가 및 정책담당자들을 대상으로 하였다. 조사를 위한 설문지가 적절하게 설계되었는지를 알아보기 위해, 3차에 걸친 예비조사(pilot study)와 사전검사(pre-test)를 실시하였다. 연구문제 검증에서도 확인하였듯이, 한국이 20세기의 꽃으로 등장했던 문화산업 등에서 도구적 이성의 견제 없는 질주가 여전히 역사성을 넘어서지 못하고 현재성을 지니게 된다면, 우리는 정신의 시대에 진입하지 못하고 낙후된 주변국이 될 수밖에 없을 것이다. 21세기 문화산업에서 우리가 판단하게 될 디자인의 가치는 계몽의 원리에 대한 '역사성'과 '현재성'의 변증법에 달려있는 것이며, 새로운 철학, 새로운 문명, 새로운 세계를 열어가는 것이다.

The purpose of this study was to investigate i) the current state of washing knowledge and washing habits ii) the effect of washing behaviors on washing satisfaction. A survey questionnaire was developed and implemented to married women in their 30's or 40's. A total of 210 responses were analyzed by frequency analysis, t-test and ANOVA with PASW18.0. The results are as follows. First, the ways in which women do the laundry was analyzed. Married women in their 30s and 40s usually do the laundry at home and are familiar with washing symbols and do not rely on common sense. Most of them like to rely on the washing machine guidelines for detergent concentration and use the right amount for environmental protection. They also adjust the washing machine setting effectively considering laundry time, water temperature and care label. Second, the groups divided by demographic variables showed meaningful results about washing knowledge. Particularly, there is no significant difference on washing knowledge between housewives and career women. Third, the groups divided by the levels of washing habits showed suggestive results about washing satisfaction. The groups who have correct washing habits generally a indicated high degree of washing satisfaction. Finally, marketing implications for the businesses of laundry, laundromat and the manufacturers of washing machine are suggested.

Location-based services (LBSs) have become popular in recent years due to the ever-increasing usage of smart mobile devices and mobile applications through networks. Although LBS application provides great benefits to mobile users, it also raises a sever privacy concern of users due to the untrusted service providers. In the lack of privacy enhancing mechanisms, most applications of the LBS may discourage the user's acceptance of location services in general, and endanger the user's privacy in particular. Therefore, it is a great interest to discuss on the recent privacy-preserving mechanisms in LBSs. Many existing location-privacy protection-mechanisms (LPPMs) make great efforts to increase the attacker's uncertainty on the user's actual whereabouts by generating a multiple of fake-locations together with user's actual positions. In this survey, we present a study and analysis of existing LPPMs and the state-of-art privacy measures in service quality aware LBS applications. We first study the general architecture of privacy qualification system for LBSs by surveying the existing framework and outlining its main feature components. We then give an overview of the basic privacy requirements to be considered in the design and evaluation of LPPMs. Furthermore, we discuss the classification and countermeasure solutions of existing LPPMs for mitigating the current LBS privacy protection challenges. These classifications include anonymization, obfuscation, and an encryption-based technique, as well as the combination of them is called a hybrid mechanism. Finally, we discuss several open issues and research challenges based on the latest progresses for on-going LBS and location privacy research.

Purpose - The current study examines the shopping behavior of Chinese tourists who purchase Korean cosmetics when visiting Korea, based on expectancy-disconfirmation of shopping satisfaction and brand attitude toward Korean cosmetics. A moderating effect of consumer conformity on the relationships between cosmetics selection factors and two dimensions of disconfirmation - expectation and performance is also examined. Research design, data, and methodology - We conducted a survey with 250 Chinese tourists who visited Jeju, Korea and had purchased Korean cosmetics during their stay. Excluding 43 respondents' inputs because of incomplete answers and missing values, 207 responses were used in the final analysis. All hypotheses were tested using structural equation model (SEM). Results - We found that the Chinese tourist expectations had positive impact on their satisfaction, and the factors for cosmetic selection had a positive effect on shopping satisfaction and brand attitude. A moderating effect of consumer conformity was found to be significant. Conclusions - Given the significantly increased demand for Korean cosmetics from Chinese tourists, Korean cosmetics firms need to better understand cosmetics selection attributes and preference of Chinese tourists, which can provide a guideline to develop retail stores and distribution outlets for Chinese tourists.

Security has been considered one of the most critical issues for managing IT resources in many organizations. Despite a growing interest and extensive research on security at various levels, little research has focused on the comparison of security knowledge levels between different cultures. The current study investigates and compares the security knowledge level between Korea and the U.S. Based on the literature review of spyware, Hofstede's cultural dimensions, and security knowledge, this study identifies three constructs (i.e., security familiarity, spyware awareness, and spyware knowledge) to examine the difference of security knowledge levels between Korea and the U.S. Six hundred ninety-six respondents from Korea and the U.S. participated in the survey, and an in-depth analysis based on analysis of covariance (ANCOVA) was carried out. The results show that the levels of security familiarity, spyware awareness, and spyware knowledge are significantly lower in Korea than in the U.S., as expected. These findings present a significant association between national culture and security knowledge, and the degree of individualism (or collectivism) plays an especially critical role in the perception of security. A number of implications for academia and practitioners emerge. Limitations and future research directions are discussed in the conclusion.
