The current location based services provide maps and nearby information, or provide a route to a specific destination. A route recommendation system recommends the best route that suits the evaluation criteria for each user. The existing personalized path recommendation system recommends the route under the assumption that the user’s preference is constant regardless of the change of the time zone. However, there is a problem in that it does not reflect requirements that important factors to users can be different for each time zone, such as importance of moving distance in morning time and importance of risk in late time. In this paper, we propose a Dijkstra algorithm considering time attributes to overcome this limitation. In addition, we suggest an efficient algorithm that can search the path reflecting the change of the weight of the preference factor according to the time zone using the G-tree index structure that effectively expresses the road network.

Collaborative consumption (CC) occurs in organized systems or networks in which participants conduct sharing activities in the form of renting, lending, trading, bartering, and swapping of goods, services, transportation solutions, space, or money. Information and communications technologies (ICTs) that have emerged with CC. CC is expected to alleviate social problems such as hyper-consumption, pollution, and poverty by lowering the cost of economic coordination. In this study, we investigate the influence of educational experience and expected benefits of CC participation (intended to using and providing CC) of Adolescent Consumers. The subjects for the study were 418 high school students. Data was analyzed through frequency analysis, mean, standard deviation, t-test, ANOVA, Pearson`s correlation, and hierarchical multiple regression analysis using SPSS Win 21.0. The results of this study are as follows. First, the significant positive relationship found between CC participants (intent to use and provide CC), educational experience (home education, school education, and mass media) and expected benefits (social benefit, economic benefit, enjoyment, community effect, and reputation). Second, enjoyment, mass media, reputation, social benefit, home education and school education values were variables that influenced the using participation intention for CC. Third, the major variables influencing the providing participation intention CC were home education, enjoyment, gender, community effect, and mass media values.

The purpose of this study was to identify the factors, which influence impulsive buying at duty-free shops. This involved an investigation into the effects of demographic characteristics, the types of purchased items, and the situational and emotional factors affecting impulsive purchasing behaviour in consumers, who had bought items from duty free shops in the past three years. The findings are as follows. Firstly, while beverage and cosmetic items were found to encourage impulse buying, in general demographic variables and type of product had only a slight influence. Secondly, the situational factors of price benefits, overseas luxury branding, and ease of access in the duty free shopping area all had a definite positive influence. Thirdly, with regard to emotional factors, positive emotion was found to have strong augmenting effect on impulsive purchasing. The findings can be used in the development of educational materials to prevent impulsive purchasing and promote sensible consumer behaviour.

몸의 소비문화적 의미와 현상에 대한 고찰

정주원(Jung Joo Won) 한국소비문화학회 2006 소비문화연구 Vol.9 No.1

본 연구는 몸에 대한 관심이 급증하고 있는 현대 소비사회에서 현대인의 몸의 의미가 어떻게 소비의 관계 속에서 위치하는가를 살펴보고자 하였다. 이를 위해 기존 연구들과 2차 자료들을 중심으로 소비대상이 되고 있는 몸의 소비문화적 의미와 대표적인 몸 소비현상을 소비문화적 관점에서 분석해 보았다. 분석결과 현대 소비사회에서 몸은 내면이 아닌 외형에 치우쳐 끊임없이 관리되어져야 하는 소비대상으로 간주되고 있었으며, 각종 소비재로 둘러싸인 몸은 자신의 욕구를 드러내는 역할을 함으로써 구별짓기와 차별화를 위한 기제로 작용하고 있었다. 또한 외형적인 몸이 소비자의 정체성을 나타나는 상징이자 기호로 작용함으로써 소비자는 계속적으로 몸에 대한 관심을 가지고 소비를 하는 것으로 나타났는데, 이는 각종 미용 산업의 성장과 이미지를 생산해내는 대중매체의 영향력에 의해 촉진되고 있었다. 이러한 측면은 특징적인 몸에 대한 소비현상들 즉 얼짱ㆍ몸짱에 대한 지나친 관심과 다이어트 열풍, 각종 미용관련 용품과 확대되어지는 성형수술에서 잘 반증되고 있었다. 이와 같이 소비사회는 소비자에게 몸과 관련된 상품의 선택 폭을 다양하게 해 주었지만, 정형화된 획일적 아름다움을 사회적으로 확대 재생산하고 있으며, 소비자의 몸은 상품의 소비에 길들어지며 심각한 병폐를 낳고 있다. 이러한 현상은 몸에 대한 근본적인 자아를 상실해가는 것으로 이상적인 이미지를 추종하고자 상품을 소비하고 이를 통해 타인에게 인정받고 타인과 구별되고자 하는 현대 소비문화의 특징이자 문제점이라 할 수 있다. 이에 사회 전반적으로 외형적인 몸 소비문화에 빠져 있는 현상에 대한 자성이 요구되어지며 건강한 몸 소비문화의 정착을 위해 소비자 자신 뿐 아니라 기업, 미디어, 정부와 학계의 개선 노력이 절실히 필요하다. 몸은 단순히 보여 지는 것이 아니라 나의 정신과 주체를 담고 있는 것이라는 몸에 대한 본질적이고 온전한 이해와 함께 건강하고 바람직한 소비 가치관의 지침과 대안적 규범들이 제시되어야 할 것이다. This study was carried out to assess how the bodies of modern consumers have become related with consumption in the modern society. Based on existing studies and additional materials, we taken a look at the consumer cultural significance of the body together with main body consumption phenomena from a cultural perspective. As a result, we could see that the body in the modern day consumer society was considered as an outer asset and a subject of consumption that needed to be continuously taken care of. The body decorated from head to toe in a variety of consumer goods shows the wants of that individual as a means of social distinction and differentiation. In addition, the outer appearance of one’s body acts as a symbol or sign of the consumer’s identity, which is why consumers persistently pay attention to their bodies when buying goods, and this phenomenon is being accelerated by the growth of various beauty industries and the outer images portrayed by the influential mass media. This tendency is shown in many areas of body consumption, especially in the current trends of ‘perfect face, perfect body complex’, slimming diets, various beauty and cosmetic supplies, and the expansion of plastic surgery. Our consumer society has provided a wide and varying range of body products, but at the same time has portrayed and reproduced a certain criteria of beauty, making the consumers’ bodies adapt to product consumption. An introspective look is required of the social trends of pursuing outer body consumption cultures, and efforts on the part of not only the individual consumers but also companies, the media, the government, and the academic field are needed for the establishment of a healthy body consumption culture. Healthy and appropriate consumer value regulations and alternative methods as well as a fundamental and wholesome recognition of the body are needed for the body to be properly seen as a vessel of one’s soul and identity.

정주원(Joowon Jung),조소연(So Yeon Cho) 한국환경교육학회 2021 環境 敎育 Vol.34 No.2

본 연구의 목적은 코로나19 전후 환경의식과 친환경소비행동 변화를 살펴보고, 환경의식과 친환경소비행동의 관계에서 환경보호비용지불의사의 상호작용 효과(interaction effects)를 검증하는 것이다. 이를 위해 온라인 설문조사를 실시하여 전국 20∼69세 이하의 성인 443명을 최종분석에 활용하였으며, 기술통계, Paired t-test, K-medians 군집분석, 위계적 중다회귀분석, 단순 기울기검증(simple slope)을 실시하였다. 연구결과는 다음과 같다. 첫째, 코로나19 전후 환경의식과 친환경소비행동 변화를 살펴본 결과, 코로나19 이전에 비해 코로나 이후가 모두 유의미하게 높게 나타났다. 둘째, 환경보호비용지불의사 수준이 낮은 집단에 비해 높은 집단에서 환경의식과 친환경소비행동 변화수준이 높게 나타났다. 셋째, 환경의식과 친환경소비행동 관계에서는 구매행동 및 처분행동에서 환경보호비용지불의사가 높은 집단의 의미 있는 상호작용 영향력이 나타났다. 이를 통해 환경보호비용지불에 대한 호혜적 환경교육을 통한 친환경소비행동으로의 실천적 방안이 요구된다. The purposes of this study lie in investigating the changes in environmental consciousness and environment-friendly consumption behavior before and after the COVID-19 pandemic, as well as verifying the interaction effects that the willingness to pay environmental protection expenditures has in the relationship between environmental consciousness and environment-friendly consumption behavior. An online survey was conducted, through which responses from 443 adults between 20∼69 years of age were collected and used in the final analyses. Paired t-tests, k-medians cluster analyses, hierarchical multiple analyses, and simple slope analyses were performed. The results are as follows. First, upon investigating the changes in environmental consciousness and environment-friendly consumption behavior before and after the COVID-19 pandemic, there were significant increases in both factors after the pandemic, as compared to before the pandemic. Second, the levels of change in environmental consciousness and environment-friendly consumption behavior were larger in groups that were more willing to pay environmental protection expenditures, compared to groups that were less willing to do so. Third, in the relationship between environmental consciousness and environment-friendly consumption behavior, meaningful interaction effects in purchasing and selling behaviors were observed in groups more willing to pay environmental protection expenditures. This suggests that it is necessary to develop practical measures that increase environment-friendly consumption behavior through reciprocal education on paying the environment protection expenditures.

인간 배아줄기세포 임상적용을 위한 배양환경으로서 feeder-free 및 xeno-free 조건에 대한 연구 동향

정주원 ( Ju Won Jung ),오선경 ( Sun Kyung Oh ),최영민 ( Young Min Choi ) 서울대학교 인구의학연구소 2011 人口醫學硏究論集 Vol.24 No.-

The developmental potential of human embryonic stem cells (hESCs) makes them an useful tool in clinical research and important role in the future of regenerative medicine. Because traditional hESC culture systems have been relied on animal derived products and mouse feeder layers, they can cause expose to potential immunogenicity and contamination with pathogens. For clinical applications, hESCs must be cultured in chemically defined, xeno-free culture systems that support self renewal and directed differentiation. We reviewed methods for establishment and efficient propagation of hESCs under feeder-free and xeno-free culture conditions for cell therapy applications.

정주원 ( Juwon Jung ),이봉우 ( Bongwoo Lee ) 한국과학교육학회 2016 한국과학교육학회지 Vol.36 No.3

본 연구의 목적은 예비과학교사들의 수업설계와 실제수업의 불일 치내용을 분석하고 그 발생 원인을 고찰하는 것이다. 이를 위해서 2015년 4월부터 5월까지 실시된 교육실습에 예비과학교사 20명이 참여하였고, 예비과학교사들이 작성한 수업지도안과 수업을 분석하여 불일치한 내용을 추출하고, 면담을 실시하였다. 주요 연구 결과는 다음과 같다. 첫째, 도입 단계에서는 ``주의집중 및 동기유발`` 영역에서 가장 많은 불일치 사례가 발견되었으며, 예비과학교사들은 동기유발 요소를 다른 형태로 수정한 경우가 많았다. 둘째, 전개 단계에서는 가장 많은 불일치 사례가 발견되었는데, 특히 ``학습내용제시`` 활동에서 학습내용을 추가적으로 제시하여 수업을 하는 경우가 많았다. 셋째, 마무리단계에서는 시간의 부족으로 ``학습내용요약`` 활동이 누락된 사례가 많았다. 넷째, 예비과학교사들의 수업계획과 실제수업의 불일치 발생원인은 내부요인과 외부요인이 비슷하였으며, 외부요인 으로는 지도교사의 피드백과 학생반응에 의한 변화가 가장 많이 발생 하였다. 추가적으로 예비과학교사의 수업전문성 신장과 관련하여 반성적 멘토링 프로그램, 지도교사의 중요성, 시간 관리의 중요성 등과 관련된 시사점을 논의하였다. The purpose of this study is to analyze the mismatch between instructional design and teaching practice of pre-service science teachers and to investigate the cause of these mismatches. Twenty pre-service science teachers took part in teaching practicum for four weeks from Apr. 2015 to May 2015 and we analyzed their lesson plans and videos of these lessons. After that, we interviewed the pre-service science teachers in order to know the cause of these mismatches and additional informations. The main findings are as follows. First, in the introductory stage, we found more mismatch in the "attention and motivation stimulation" area than any other area. Many pre-service science teachers corrected their ``motivation practice`` in different forms. Second, we found out that the most mismatch occurred in the evolving stage. Many pre-service science teachers added learning contents in "learning content presentation" area. Third, in the closing stage, many pre-service science teachers omitted the "leaning content summary" area in the lack of time. Fourth, the number of mismatches by internal factors is similar of by external factors. The mismatches by external factors were mainly by feedback of guidance teacher and change by students` response. In addition, we discussed the implications related to reflective mentoring program, importance of guidance teacher, importance of time management etc.

성인기이전의 부정적 생활사건 경험이 성인기 우울에 미치는 영향

정주원(Jung, Joo Won) 한국생활과학회 2014 한국생활과학회지 Vol.23 No.6

The purpose of this study is to examine depression in adulthood caused by the influence of negative life events (disaster·accident, physical violence and emotional abuse) in pre-adulthood and explore the mediator effect of interpersonal maladjustment. To carry out such task, 974 people who have had negative life event experiences before the age of 18 were chosen based on the data from the 2012 Korean General Social Survey(KGSS) and Stata 10.0 was used to do the analysis. As a result, it was found that there was a direct relationship between negative life events in pre-adulthood and depression in adulthood. Specifically, experiences from an accident or disaster had a direct impact on depression. Moreover, experiences of physical violence and emotional abuse not only had a direct influence on depression, but also through maladjustment, it had an indirectly partial mediator effect that increases the chances of depression. Through this result, it was evident that negative life events from pre-adulthood had a negative effect on continuous interpersonal maladjustment as well as psychological welfare throughout the adulthood. Therefore, there needs to be thorough prevention measures on negative life events in pre-adulthood and strongly take post treatment into consideration. Through building a safe life environment, great deal of social support from social organizations should be prepared systematically.
