Due to the social atmosphere that neglects sexual communication, young people are having difficulty in sexual self-assertion, such as not being able to demand active contraception. These difficulties cause social problems such as unwanted pregnancy, experience of artificial abortion, and the occurrence of sexual mediated diseases due to unprepared sexual intercourse. To solve this problem, the purpose of the study was to establish correct sexual values of young people and improve their ability to make healthy sexual decisions. In this study, the theoretical review of youth sex culture, the current status and limitations of sex education at home and abroad were analyzed, and based on this, surveys, in-depth interviews, and co-creation workshops were conducted to set the problem of sex culture and desirable direction of sex culture. In addition, through in-depth interviews with experts, specific areas for improving youth sex culture were confirmed. By synthesizing the previous survey, five personas were designed according to behavioral mapping and a journey map was produced. Based on the pain points of the persona derived from the travel map, a four-step process was established to diagnose, establish, practice, and plan. The results and contents of the study are as follows. First, a ‘Couple Growthtalk.’ toolkit in the form of a workbook was produced. The toolkit consists of four stages: activities to establish sexual values and activities for sexual decision-making, and was produced with an emphasis on improving sexual communication between lovers. Second, through the support of the Seoul Metropolitan Government’s governance project, the ‘Couple Growthtalk.’ toolkit in the form of an easy-to-access mobile web has been actually implemented, and it can be expected to spread through the Kakao Talk sharing function. Third, for the ‘Couple Growthtalk.’ toolkit, we tried to increase the participation of young people by producing promotional videos in collaboration with companies. Based on the previous text, This study has theoretical significance in that it discovered sexual communication problems of youth sex culture that were not covered in previous studies and derived solutions through service design methodology, and has practical significance in that a real prototype for a healthy youth sex culture was implemented by the collaboration of government-company-individual through the Bottom- Up method that young people work as a main body. This is expected to help the growth of a society of healthy sex culture where the happiness and safety of young people are realized in the future. 성적 의사소통을 금기시하는 사회적 분위기로 인해 청년들은 적극적인 피임을 요구하지 못하는 등 성적 자기주장의 어려움을 겪고 있다. 이러한 어려움은 원하지 않은 임신과 인공유산 경험, 준비되지 않은 성교로 인한 성매개성 질환 발생 등의 사회적 문제를 야기한다. 이를 해결하기 위해, 본 연구는 청년의 올바른 성적가치관의 형성과 건강한 성적 의사 결정을 내릴 수있는 능력 향상을 목적으로 한다. 이를 위해 청년 성문화의 이론적 고찰과 국내외 성교육 현황을 분석하였고, 이를 바탕으로 설문조사, 심층 인터뷰 그리고코크레이션 워크숍을 진행하여 수요자가 생각하는 현성문화의 문제점과 바람직한 성문화의 방향성을 설정하였다. 또한, 전문가 심층 인터뷰를 통해 구체적인청년 성문화의 개선 필요 영역을 종합하여 행동 매핑에 따라 5명의 퍼소나를 설계하고 여정 맵을 제작하였다. 여정 맵에서 도출한 퍼소나의 페인 포인트를 바탕으로 진단하기, 확립하기, 연습하기, 계획하기 4단계의 프로세스를 구축하였다. 연구 결과 및 내용은 다음과 같다. 첫째, 워크북 형태의 ‘성장톡’ 툴킷을 제작하였다. 툴킷은 성적 가치관을 성립하기 위한 활동과 성적 의사 결정을 위한 활동으로 총 4가지 단계로 구성되며, 연인 간 성적 의사소통 향상에 중점을 두어 제작하였다. 둘째, 서울시거버넌스 사업의 지원을 통해 접근성이 용이한 모바일 웹 형태의 ‘성장톡’ 툴킷을 실제 구현하였으며, SNS 공유기능을 통해 확산을 기대할 수 있다. 셋째, ‘성장톡’ 홍보영상을 제작하기 위해 기업과 협업하여청년들의 참여를 높이고자 하였다. 본 연구는 선행연구에서 다루어지지 않았던 청년성문화의 성적 의사소통 문제를 발견하고 서비스 디자인 방법론을 통해 솔루션을 도출했다는 점에서 이론적 의의가 있다. 또한, 정부-기업-개인이 협업하여바텀-업(Bottom-Up) 방식으로 청년이 주체가 되어건강한 청년 성문화를 위해 실제 프로토타입을 구현했다는 점에서 실무적 의의가 있다. 이는 향후에 청년의 행복과 안전이 구현되는 건강한 성문화 발전에 기여할 것으로 기대된다.

Strategies for Minimizing Glial Response to Chronically-implanted Microelectrode Arrays for Neural Interface

이예나,전상범 대한의용생체공학회 2014 Biomedical Engineering Letters (BMEL) Vol.4 No.2

For several decades, the intracortical penetrating microelectrodearrays have been widely employed for the purpose of neuralrecording and stimulation in nervous system. However, thelong-term application is limited due to the tissue reaction tothe implanted electrode array. The tissue response includesthe degeneration of nerve cells as well as the formation ofdense glial sheath adjacent the implanted electrode calledgliosis. The glial encapsulation deteriorates the capacity ofelectrodes to communicate with neurons by electricallyisolating the devices from the neighboring brain regions. Toexamine and overcome these critical obstacles of microelectrodearray for chronic applications, a number of studies have beenperformed to date including the reduction of electrode geometry,the use of flexible materials for electrode substrates, thepharmacological suppression of the cellular reaction, and theoptimized surgical techniques. In this review, the studies toclarify the mechanism of the glial response in central nervesystem (CNS) will be described and a variety of strategiesfor minimizing the glial responses in CNS will be examined.

이예나,김지명,이경옥,Visanou Hansana,김유리 한국영양학회 2018 Journal of Nutrition and Health Vol.51 No.6

Purpose: The purpose of this study was to evaluate the food insecurity status and dietary behavior and examine the association between the food insecurity status and consumption of processed beverage for secondary school students in Vientiane, capital city of Lao PDR. Methods: The study subjects are 714 students (boys = 307 and girls = 407) in four secondary schools (Chao_Anouvong, Phiavat, Saysetha, and Chansavang) of Vientiane, Lao PDR. Data on study subject’s demographic characteristics, dietary behavior, food insecurity, and Mini Dietary Assessment (MDA) index were collected. A “Self-Administered Food Security Survey Module for Children Aged 12 Years and Older” developed by the United States Department of Agriculture (USDA) was used for the food insecurity assessment. Results: As a result, 72.7% of the subjects were in a state of food insecurity, and food security was associated with higher socioeconomic status (higher life satisfaction, higher parent’s education attainment, higher item ownership, fewer number of siblings, and having more lunches at the school restaurant than at home). Compared to the food insecurity group, the frequency of breakfast, self-rated diet, and the total score of MDA index were higher in the food security group. On the other hand, multiple logistic regression analysis showed that ‘food security’ was also associated with a higher consumption of processed beverages (OR 1.544; 95% CI 1.078-2.213; p = 0.018). Conclusion: Improving the quality of the diet is essential for adolescents in both the food insecurity and food security groups in Lao PDR. Therefore, it is necessary to provide well organized nutrition education and establish adequate nutrition policy for adolescents in Lao PDR. 본 연구는 라오스 비엔티안 지역 일부 청소년을 대상으로 식품 불안정 상태를 파악하고, 이에 따른 식행동 및 가공 음료 섭취를 비교하고자 진행되었다. 미국 농무부에서개발한 식품 안정 조사 모듈을 통해 조사한 결과, 전체714명의 대상자 중 519명, 즉 72.7%가 식품 불안정 상태로 나타났다. 식품 안정군 (Food Security, FS)이 식품 불안정군 (Food Insecurity, FI)에 비해 ‘삶에 대한 만족도’, ‘부모의 교육 수준’, ‘가정 내 소유하고 있는 물품의 수’가더 높았고 ‘형제자매 수’는 더 적었던 것을 통해 식품 불안정이 낮은 사회 경제적 상태 (socioeconomic status, SES)와 유의한 관계가 있음을 확인할 수 있었다. FI군보다FS군의 가공 음료 섭취 및 점심 식사를 밖에서 사 먹는 비율이 유의적으로 더 높게 나타난 것 역시 FI군의 낮은SES가 반영된 결과라고 생각할 수 있다. 본 연구에서 가장 주목할 만한 결과는 FS군이 FI군에 비해 ‘아침 식사 섭취 빈도’ 및 ‘스스로 평가한 식사의 질’, ‘간이 식생활 진단’을 통해 평가한 결과의 총점이 더 높게 나타났으나, ‘식품 안정’에서 높은 수준의 가공 음료 섭취 가능성 또한1.544배 증가하였다는 것이다. 이는 낮은 식사의 질이 단지 식품 불안정에 따른 문제가 아님을 의미하므로, 라오스청소년을 대상으로 한 체계적인 영양 교육 및 정책 마련은추후 빠르게 진행되어야 할 것으로 사료된다.

이예나,최은정,김명주 한국디지털정책학회 2018 디지털융복합연구 Vol.16 No.2

Smartphones and PCs have become essential components of our daily life. People are expressing their opinions freely in SNS by using these devices. We are able to predict public opinions on specific subject by analyzing the related big data in SNS. In this paper, we have collected opinion data in SNS and analyzed reputation by text mining in order to make a prediction for the will of the people before 19th presidential election in South Korea. The result shows that our method makes more accurate estimate than other election polls. 최근 스마트폰과 PC 이용이 대중화됨 따라 웹상에 데이터가 기하급수적으로 축적되고 있다. 특히 SNS를 통해서 자유로운 의사소통은 물론 간편한 정보공유가 가능하여 다양한 의견들이 대량 데이터 형태로 축적된다. 이러한 데이터들을 분석하여 특정 주제에 대한 여론을 예견하는 빅데이터 기반의 여론분석기술이 주목받고 있다. 본 논문에서는 SNS 상에 표현된 사용자들의 의견을 수집하고 분석하여 대한민국 19대 대통령 후보자들에 대한 유권자들의 숨어있는 표심을 분석해보았다. 이를 위해 19대 대선 후보에 관한 SNS상의 정보를 수집한 후 텍스트 마이닝 기법과 오피니언 마이닝 기법을 적용하여 언급 빈도수와 관련 키워드를 통한 평판 분석을 실시하였다. 본 논문에서 제시한 SNS를 통한 19대 대선후보의 평판분석결과가 기존의 여론조사결과에 비하여 더 정확하게 예측했음을 확인할 수 있다.

The Effect of Storytelling Constructs on Consumer Attitude and Purchase Intention in Consumer Cooperatives

이예나,이상훈 한일경상학회 2014 韓日經商論集 Vol.65 No.-

In marketing field, story can be used as an effective communication tool conveying information of the company. This study aims to explore the potential of storytelling methods as a marketing communication tool for consumer cooperatives, and to analyze the effect of storytelling on consumer - as well as a member of cooperatives - attitude and purchase intention using an empirical study. Generally, consumers recognize that primary products producers have many difficulties in the process of production. This cognition can be basis to elicit consumers’ emotional attitude such as sympathy or empathy. Especially, consumer cooperatives in Korea have various policies to build a close relationship between producers and consumers. Therefore we assume that members of consumer cooperatives develop distinctive producer-consumer relationship and this could serve as a one of conditions under which storytelling–especially emotional one - appeals to consumers more effectively. For these purposes, we set three constructs of storytelling - main character of storytelling, message appealing type, and the object type of the message - as independent variables. We conduct five type of survey, each of which has a different test ad that includes differently combined elements of independent variables. We can summarize the results of the survey as follow. First, any kind of producer’s emotional storytelling has more influence on consumer attitude than producer’s rational one. Second, consumers feel friendlier toward producer’s emotional storytelling of primary product than that of processed product. Third, the relation between consumer attitude and purchase intention was shown positively. By finding conditions to utilize storytelling effectively, this study provides insights to consumer cooperatives and other organizations facing similar marketing condition.

Sintering of porous ceramic of diatomite according to molding pressure and PEG content

이예나,안석환,남호석,남기우 한양대학교 세라믹연구소 2018 Journal of Ceramic Processing Research Vol.19 No.6

Diatomite powder, a naturally occurring porous raw material, was used to make ceramic materials with porosity and highstrength. The sintering behavior of the diatomite powder at various sintering temperatures suggests that diatomite monolithswith a high porosity and strength can be prepared at 1100 oC. The compressive strength of the sintered diatomite monolithsincreased as the sintering temperature increased, and the molding pressure of 2MPa and the binder of 18.6 wt.% wereexcellent. When the sintering temperature rises, the diatomite powder is melted, and its pores gradually disappear. SEMimages show that strengthening begins with the formation of inter-particle bonds at a low sintering temperature.

3차원 Arbitrary Lagrangian-Eulerian 기법을 사용한 자유 대기 중 폭발 해석의 최적 격자망 크기 산정

이예나,이태희,박다원,최영준,홍정욱,Yena Lee,Tae Hee Lee,Dawon Park,Youngjun Choi,Jung-Wuk Hong 한국전산구조공학회 2023 한국전산구조공학회논문집 Vol.36 No.6

폭발 수치해석 기법 중 Arbitrary Lagrangian-Eulerian(ALE)는 구조물의 파괴뿐만 아니라 폭발 이후 충격파의 전파 과정까지 관찰할 수 있는 장점이 있다. 그러나 동적 해석 시 유한요소 모델의 격자망 크기가 일정 수준 이하로 감소하게 되면 해석 결과의 신뢰도가 부정확해진다. 본 연구에서는 ALE 수치해석 기법을 활용하여 대기의 격자망 크기가 해석의 정확도에 미치는 영향을 조사한다. 다양한 조건의 격자망 크기와 폭발 중량을 갖는 대기 중 폭발모델을 구축하고, 폭발 중심으로부터 거리에 따른 폭발압력을 관찰한다. 수치해석과 실험에서 얻은 최대 폭발압력 결과에 대해 평균 제곱 오차를 계산하여 최적의 격자망 크기를 제안하고, 제안된 크기를 바탕으로 폭발물 중량과 대기의 최적 격자망 크기에 대한 상관관계를 분석한다. 본 연구는 다양한 중량을 가진 폭발물 해석에서 최적의 격자망 크기를 제공함으로써 신뢰성이 향상된 폭발 수치해석 모델 개발에 도움이 될 것으로 기대한다. The arbitrary Lagrangian-Eulerian (ALE) method has been extensively researched owing to its capability to accurately predict the propagation of blast shock waves. Although the use of the ALE method for dynamic analysis can produce unreliable results depending on the mesh size of the finite element, few studies have explored the relationship between the mesh size for the air domain and the accuracy of numerical analysis. In this study, we propose a procedure to calculate the optimal mesh size based on the mean squared error between the maximum blast pressure values obtained from numerical simulations and experiments. Furthermore, we analyze the relationship between the weight of explosive material (TNT) and the optimal mesh size of the air domain. The findings from this study can contribute to estimating the optimal mesh size in blast simulations with various explosion weights and promote the development of advanced blast numerical analysis models.
