속성기반 암호화를 이용한 원격 헬스케어 모니터링 시스템

송유진,도정민,Song, You-Jin,Do, Jeong-Min 한국정보처리학회 2012 정보처리학회논문지 C : 정보통신,정보보안 Vol.19 No.1

원격 헬스케어(e-Healthcare) 서비스에서 취급되는 의료정보는 개인의 프라이버시를 침해할 수 있으므로 암호화 등의 보안기술 도입이 필수적이다. 민감한 의료정보를 보호하기 위해서 접근 권한을 위임받은 사용자만 데이터에 접근 가능하며 또한, 위임된 접근 권한을 철회하는 기능이 필요하다. 이러한 요구사항에 근거하여 속성기반 암호화가 제안되었다. 본 논문에서는 안전한 원격 헬스케어 서비스를 위해서 의료데이터의 접근 권한에 대한 위임 및 철회기능을 수행할 수 있는 속성기반 암호화를 원격 헬스케어 모니터링 시스템에 적용한다. 그리고 속성기반 암호화를 이용하여 원격 헬스케어 모니터링 시스템을 구성한다. 마지막으로 시스템 이용에 장애가 될 수 있는 사용자간의 공모 공격에 대해서 분석한다. To ensure privacy of individual information in remote healthcare service, health data should be protected through a secure technology such as encryption scheme. Only user who delegated decryption right can access to sensitive health data and delegator needs capability for revocating access privilege. Recently, in ubiquitous environment, CP-ABTD(Ciphertext-Policy Attribute-Based Threshold Decryption with Flexible Delegation and Revocation of User Attributes) which extends CP-ABE(Ciphertext-Policy Attribute-Based Encryption) has been proposed for these requirements. In this paper, we construct remote healthcare monitoring system with delegation and revocation capability for attribute in CP-ABTD. Finally, we analyze collusion attack between users in our system.

쇼핑 챗봇에 대한 소비자 반응 연구: 에이전트와 메시지 유형 효과를 중심으로

송유진,김민희,최세정 한국에이치씨아이학회 2019 한국HCI학회 논문지 Vol.14 No.2

As AI technology develops, its application has been extended to diverse fields. In particular, AI-enabled Chatbot services have garnered growing attention and such services are more important as a tool of communication in mobile shopping. However, research on chatbots is in its early stage and the understanding of chatbots in the context of mobile commerce is very limited. The purpose of this study is to empirically investigate consumer responses to a shopping chatbot with a focus on the effects of chatbot agent types and message types. Specifically, a 2×2 between-subjects experimental design, with the agent type (secretary/friend) and the message type (factual/evaluative) as the independent variables, was employed. The results show that although main effects of chatbot agent and message types are not found, interaction effects between chatbot agents and message types on consumer responses are significant. Specifically, when the agent type was a secretary, consumer responses to product recommendation with a factual message were more positive. On the other hand, in the case of the friend agent, the evaluative message led to more positive responses. The findings suggest that communication elements are important in the understanding of consumer responses to chatbots in mobile shopping and effective strategies for utilizing chatbots for mobile commerce should be considered. 인공지능(AI) 기술이 발달함에 따라 다양한 영역에서 활용되고 있다. 인공지능을 활용한 챗봇(Chatbot)의 이용도 여러 분야로 확대되고 있으며, 특히 모바일 쇼핑 이용이 증가하면서 챗봇 서비스의 소비자와의 소통 기능이 주목 받고 있다. 그러나 챗봇에 대한 연구는 초기 단계이며 모바일 커머스에서 이용하는 챗봇에 대한 선행연구는 아직미비하다. 따라서 본 연구는 쇼핑 챗봇에 대한 소비자 반응을 실증적으로 살펴보고 의인화된 챗봇의 에이전트로서의유형과 메시지 유형이 어떠한 영향을 주는지를 검증하고자 하였다. 구체적으로 챗봇 에이전트 유형(비서/친구)과 메시지 유형(사실/평가)을 독립변수로 2×2 집단 간 실험을 수행하였다. 연구 결과, 챗봇 에이전트 와 메시지 유형이소비자의 챗봇에 대한 지각된 인식 및 반응에 미치는 주효과는 발견되지 않았지만, 에이전트 유형과 메시지 유형의간 상호작용이 나타났다. 구체적으로 에이전트 유형이 비서일 때에는 사실적 메시지로 상품 추천을 하였을 때 긍정적인 영향을 미치는 반면, 친구일 경우에는 평가적 메시지 유형이 보다 긍정적인 반응을 얻는 것으로 나타났다. 이결과는 챗봇 서비스에 대한 소비자 반응을 이해하기 위해서 커뮤니케이션 요소들을 고려해야 하며 이를 적절하게 활용하여 긍정적인 경험을 유도할 수 있다는 학문적, 실무적 시사점을 제공한다.

영유아기 자녀의 건강⋅영양 및 안전에 대한 어머니의 인식

송유진,김희진 미래유아교육학회 2019 미래유아교육학회지 Vol.26 No.1

The purpose of this study was to explore the perceptions of mothers of young children about health, nutrition and safety, in the context of the various concerns and anxieties about these topics that are spreading in society nowadays. The participants of this study were 316 mothers of children aged 1 to 5 who attended kindergarten or daycare in Seoul, Incheon and Gyeonggi province. The researcher designed a questionnaire tailored specifically to the purposes of this study. The results indicated that mothers generally had a high sensibility to the health, nutrition and safety of their young children. Furthermore, there was a diverse array of reasons behind contrasting perceptions of mothers. The results of this study suggested that it was important for the mothers to give their best when it came to the health, nutrition and safety of their children. However if the mothers reacted with an excess of sensibility, their childrearing could be less effective. It would be useful to assist mothers who focused their attention exclusively on one side of the spectrum to consider diverse opinions of scholars and specialists, and to make rational decisions. 본 연구의 목적은 건강⋅영양 및 안전에 대해 다양한 걱정과 불안이 사회적으로 만연한 현 시점에서 영유아기 자녀의 건강⋅영양 및 안전 문제에 대한 어머니의 인식을 알아보는 것이다. 서울, 인천, 경기 지역의 유치원과 어린이집에 다니는 만 1∼5세 자녀를 둔 어머니 316명이 연구에 참여했고, 연구목적에 맞게 연구자가 직접 제작한 설문지를 사용하였다. 연구 결과 어머니는 전반적으로 영유아기자녀의 건강⋅영양 및 안전 문제에 대한 민감성이 높은 것으로 나타났다. 또한 영유아기 자녀의 건강⋅영양 및 안전에 대해 어머니가 가지고 있는 상반된 인식의 기저는 다양한 것으로 밝혀졌다. 본 연구의 결과는 어머니가 자녀의 건강⋅영양 및 안전을 위해 최선을 다하는 것은 중요하나, 지나치게 민감하게 반응하는 것은 부정적인 결과를 낳을 수 있다는 것을 시사한다. 또한 영유아의 건강⋅영양 및안전 문제에 대한 상반된 의견 중 한 쪽 의견에만 주의를 기울이는 어머니에게 전문가의 다양한 의견을 폭넓게 듣고 합리적인 판단을 할 수 있도록 도와야 할 필요성을 시사한다.

While, the females were higher in the case group of participating in sports than in the case of group of nonattendance in sports. 3. With regard to their depression, fatigue, confusion it was revealed that the males were lower in the case of group of nonattendance in sports than in the case of group of participating in sports. While, the females were little higher in the case of group of participating in sports than in the case of group of nonattendance in sports. 4. In regard to their vigor, males and females were higher remarkably in the case of group of participating in sports than in the case of group of nonattendance in sports.

Effects of γ-Irradiation on Antioxidant and Antimicrobial Activities and Color of Ecklonia cava

송유진,김아람,김꽃봉우리,이소영,Jin Gyu Park,김재훈,최종일,이주운,변명우,안동현 한국식품과학회 2011 Food Science and Biotechnology Vol.20 No.3

Ecklonia cava (EC) was irradiated with γ-rays at doses of 3, 7, and 20 kGy. The extraction yields, total polyphenol content (TPC), DPPH radical scavenging activity, antimicrobial activity, and color of the EC extracts were assessed. The results showed that irradiation caused an increase in the extraction yields of ethanol and water. TPC was found to be significantly increased when EC powder was subjected to irradiation, followed by ethanol and water extraction. However, DPPH radical scavenging and antimicrobial activities were stable under all irradiation conditions. In the heat and pH stability tests, the DPPH radical scavenging activities of EC ethanol extracts were not influenced by irradiation. Irradiation caused an increase in the lightness and redness of EC extracts and decreased the yellowness. In conclusion, γ-irradiation increased the extraction yield and TPC and brightened the color, while maintaining the antioxidant and antimicrobial activities.

리듬체조 난이도 콤포지션에 관한 이론적 고찰

송유진,김지희 부천대학 2004 論文集 Vol.25 No.-

본 연구는 리듬체조 지도자와 선수들의 훈련 및 지도 과정에 난이도 구성에 대한 어려움을 도와주기 위하여 각종 문헌에 따라 이론적으로 정리한 결과는 다음과 같다. 리듬체조의 난이도와 콤포지션의 문제들은 아주 중요하고 복잡하여 여러 관계성의 측면에서 완벽한 학문적 정립, 규정되어 있지 않다는 것을 알 수 있었다. 선수들 육성 과정과 심판들이 생각하고 있는 동작에 대한 난이도의 개념 정리도 여러 관련 문헌에서는 명확하고 구체적인 정의가 부족함을 볼 수 있으며, 경기 규칙 집에 있는 난이도는 일정한 운동동작에 대해 의무적으로 등급 적인 것만을 보여준다는 것을 알 수 있었다. 난이도는 법치적 성격을 띠고 있지만 과학적으로 증명되어 있지는 않으나, 리듬체조에 관련된 여러 문헌에서는 난이도의 개념을 명백히 하려는 많은 연구가 이루어지고 있으며, 그 연구를 규정하기 위하여 실제적 난이도와 주어진 난이도라는 이론까지 도입되고 있다. 그리고 난이도에 대한 실천적인 관념과 경기규칙에 대한 난이도 평가 사이에 일정한 상호관계성에 대해서도 부족함을 볼 수 있으며, 일부 문헌에서는 난이도에 강한 주관성을 띄고 있음을 볼 수 있었다. 콤포지션과의 관련 문헌 또한 일반적인 기술의 성격만 나타나고 있으며 리듬 체조와 예술과의 관련된 연구는 현저하게 부족함을 알 수 있었다. 따라서 리듬체조의 콤포지션은 예술성과 난이도와의 상호작용 성을 잠시라도 망각해서는 안 될 것이다. This study was intended to help understand the difficulty of element difficulty composition in the process of training and coaching rhythmic gymnastics directors and athletes. As a result of the literature review, the following findings were obtained : It could be found that the issues of the difficulty elements and composition of rhymic gymnastics have not still been academically fully defined and established in terms of several relations as they are very important and complicated. It was found that the process of training and educating athletes and the establishment of the concept of motion difficulty have not still been clearly and specifically defined and established in several related literature materials. It could be found that the degree of difficulty in rhythmic gymnastic motions in the book of game rules shows something of their dass in a given motion. The degree of difficulty in rhymic gymnastic motions may take on a character of rule but is not scientifically proved. But many studies have been conducted about the clarification of the concept of the degree of difficulty in rhymic gymnastic motions in several literature related to rhymic gymnastics. To define those studies, even the theory of actual difficulty and given difficulty is introduced. And it could be found that there was a lack of the mutual relationship between the practical idea of difficulty and the evaluation of difficulty in the game rule, and that there was the strong subjectivity of difficulty in the literature at large. The literature related to composition showed only the nature of general skills, and research related to rhythmic gymnastics and arts was remarkably insufficient. Accordingly, interactivity between artistry and difficulty should be borne in mind the composition of rhythmic gymnastics.

Gender and Attitude to Fair Trade: Examination of the Mediation Effect by Consumer Social Mindedness

송유진 한국마케팅과학회 2011 마케팅과학연구 Vol.21 No.1

公平交易是一种可选择商业模式,其特点于“生产商和买家之间的直接交易,对生产商来说更价格相对更高更公平,是买家和生产者之间的长期保证,依赖于信用体系,更高的劳动标准,而且更环保(Golding, 2010)。它开始是为了缩小贫富差距(主要是北半球的消费者与南半球的小规模农户和劳动者之间),因为在传统市场体系中,穷人没法提高生活质量。据美国Transfair报道,传统的咖啡豆农民卖出3美元拿铁只能获利2美分(公平交易联盟, 2010)。其基本思路是,生产者应至少赚够生产成本,并且即使价格高于市场价格,买家也应支付。没有中间商就确保了这个“高于正常市场价格”,也就是所谓的公平价格,不会很高。例如,根据公平交易标签组织的标准,传统公平交易保证咖啡农民每公斤咖啡豆最高可赚取的价格的百分之十(公平交易联盟, 2010). 最近,随着全球销量和消费者对公平交易的认识的快速上升,理解的消费者购买公平交易产品变得更加重要。以往研究主要调查了欧洲和北美消费者对公平交易产品的购买动机,以及他们的人口特征。有趣的是,消费者人口统计变量,如性别,对公平交易产品消费的影响好坏参半。一些研究表明,女性消费者对公平交易产品更感兴趣,并且这点和在其他地方研究中得出的有关道德消费(e.g., Kwong, Yau, Lee, Sin, and Tse 2003) 和商业环境中的道德抉择 (e.g., Bampton and Maclagan 2009)基本一致。然而,其他研究指出,在公平交易无性别差异(Doran 2009)。对于性别影响好坏参半的其中一个解释也许是消费者性别和性别认同之间的差异。通常情况下,社会科学中,sex是指生物学上男性和女性的区别,gender则更多与心理范畴有关((Fischer and Arnold, 1994)。普遍认为,消费研究采用性别认同作为变量比默认性别更容易解释(Fischer and Arnold, 1994)。具体实施方法之一是使用消费者男性/女性的价值取向,其与个人成长所处的文化有关,可能与生物性别一致但也可能不然(Hofstede, 2001)。虽然没有直接聚焦于女性交易,Doran研究的消费者的价值观和他们对公平交易消费的影响表明,公平交易产品的消费者往往表现为更多关注他人利益,也就是,公平交易的农民。因此,建议更在乎他人利益的女性消费者,更加关注遥远国家贫困农民的利益。因此,提出假设1如下:假设1a:女性消费者在公平交易中更积极。假设1b:个人价值取向上偏女性化的男性消费者在公平交易中会(否)更积极。如前所述,一些公平交易的研究表明,消费者人口统计数据的影响好坏参半。对于这种差异,有人认为,和其他更主要的变量相比,消费者和非消费者的人口统计学差异显得微不足道(Doran, 2009, 2010)。Doran(2010)指出,价值普遍性与公平交易消费有关。另一项研究也表明,道德消费水平影响消费者对公平交易的态度(Kim et al., 2009)。这些研究说明,一些高阶变量会影响消费者的社会责任行为,比如对公平交易更加积极的态度。此外,另一假设认为,消费者的社会意识可能会调解消费者性别取向和公平交易态度之间的关系。这个假设的原理基于男性化/女性化的价值取向的范围比较广泛,它还包括许多其他的概念,如性别平等,这就本研究课题没有直接关系(Minkov and Hofstede, 2011)。因此,与其说消费者的男性化/女性化价值取向直接影响消费态度,不如说起有更多类型的特定值。因此,提出如下假设:假设2:消费者社会意识和消费者公平交易态度正相关。假设3:个人价值取向上偏女性 ... Currently many research reported that more and more consumers consider ethical factors as one of the more critical cues in their decision making (Bray, Johns, and Kilburn 2011). This study is interested in one particular area of ethical consumption, purchasing fair trade products. Fair trade is an alternative business model which is characterized by “direct trade between producers and buyers, relatively higher and fair price for producers, long-term commitment between buyers and producers, reliance on credit system, higher labor standards, and upholding environmental concerns (Golding, 2010). It started as an effort to narrow the gap between the haves (mainly consumers of the northern hemisphere) and the have-nots (small scale farmers and laborers of the southern hemisphere) who have little chance of improving the quality of life in the conventional marketing system. According to Transfair USA, conventional coffee bean farmers receive only two cents from the sale of $3 latte (Fair Trade Federation, 2010). The basic idea is that producers should earn at least the cost of production and buyers should pay as much even though the price is higher than the market price. Having few middlemen ensures this higher-than-regular market price, which is called the fair price, not very high. For example, typically fair trade certified coffee farmers can earn ten cent premium on top of the per kilo price of coffee beans, according to Fairtrade Labeling Organization standards (Fair Trade Federation, 2010). As the global sales volume and consumers’ awareness of fair trade is increasing rapidly recently, understanding consumers who buy fair trade products gets more important. Previous research which mainly performed in Europe and North America has investigated consumers’ purchasing motivation of fair trade products, as well as their demographic characteristics. It is interesting that the effect of consumers’ demographic variables, such as gender on the consumption of fair trade products has been mixed. Some research suggested that female consumers were more interested in fair trade products in general and that was in line with the result from the research on other venues of ethical consumption (e.g., Kwong, Yau, Lee, Sin, and Tse 2003) and ethical decision making in business settings (e.g., Bampton and Maclagan, 2009). However, other studies pointed out that there were no gender differences in fair trade consumption (Doran, 2009). One possible explanation for the mixed results of gender effects might lie with the difference between sex and gender identity of consumers. Typically, in social sciences sex refers to biologically based distinction of male and female, and gender is more about the psychological aspects related to sex (Fischer and Arnold, 1994). It has been argued that gender identity has more explanatory power than sex and should be used in consumer research instead of the default sex as a variable (Fischer and Arnold, 1994). One way to operationalize gender is using consumers’ masculine/feminine value orientation, which individuals internalized growing up in their culture and might or might not be consistent with ones’ biological sex (Hofstede, 2001). While not directly deals with the focal topic of femininity, Doran’s study of consumer values and their influence on fair trade consumption indicated that consumers of fair trade products tend to exhibit higher concerns of the welfare of out-group members, that is, fair trade farmers. Thus, it is suggested that consumers with higher level of femininity, who care more about other people’s welfare, will be more interested in welfare of poor farmers in faraway countries. Thus, hypothesis 1 is proposed as below. H1a. Female consumers will show more positive attitude toward fair trade. H1b. Consumers who are more feminine (masculine) in their personal value orientation will show more (less) positive attitude toward fair trade. As mentioned earlier, several fair trad...

Management Method of Planted Plants and Immigration Plants through Monitoring on Wildflower Garden - Case Study on Seoul Samgaksan Elementary School -

송유진,진혜영,이정희,전윤창,남춘희 인간식물환경학회 2017 인간식물환경학회지 Vol.20 No.3

This study was conducted to analyze the relationship between planted plants and immigration plants by monitoring the wildflower garden constructed at Seoul Samgaksan Elementary School. The results of this study are as follows: First, plants planted in the garden 32 taxa, except for weakened only 1 taxa (Clematis patens), the remaining plants maintained or increased their populations. Among maintained Plants, that did not volume growth were 6 taxa and volume growth on the spot were 5 taxa. 15 taxa were spread around the planting area and 5 taxa spread sporadically to unpredictable areas other than the planting area. Although most of the planted plants show good growth, no special management is required, but Lonicera japonica needs the density management that cuts off the stem in the early spring and 5 sporadically spreading taxa, the planting intent of garden is attenuated, so remove the root when new leaves come out in spring. Second, the total number of plants transferred after 2 years of wildflower garden constructed were 83 taxa total, which is 2.6 times that of planted plants. The seed disseminule form was analyzed as 52% barochory, 27% anemochory&hydrochory, 16% autochory and 5% zoochory. Also about 43% of the transferred plants were estimated to been imported from soil seed bank. Third, we classified immigration plants into largely native plants and naturalized plants. The native plants were transferred to more than naturalized plants: 65 native plants, 1 cultivated plants and 17 (22%) naturalized plants. The results of the monitoring of the rooftop garden ‘Choroktteul’ in Seoul City Hall showed that there were differences in the type and number of the immigration plants depending on the distance and quality of the surrounding greenery. Fourth, the management method of immigration plants is divided into three categories: elimination, transplantation, and utilization. The 39 taxa were selected for the elimination: Invasive alien plants among naturalized plants, fast spreading plants, plants that expand sideways with rhizomes, and plants that interfere with the growth of planted plants: grow to over 1 meter in height and climbing plant. The elimination period should be dry, clear, windy day, remove the root without any residue. The transplanted plants are 18 taxa, tree, plants not suitable for habitat, and in elementary school textbooks. It is a group of 26 taxa which are used in the garden: for landscape that plants have ornamental values (flowers, leaves, and autumn colors etc.) but do not attenuate the intent of the garden, and for groundcover that plants have low plant height and fast spread. It is also possible to prevent immigration plants when you are mulching or planting plants densely populated areas when making a garden.
