The blending effects of surfactants on the polystyrene emulsion polymerization were studied. The blending of Triton X-100 and SDS affects to the interfacial properties of the styrene monomer and water phases, and finally, the properties of the polystyrene latex particles. As the blending ratio of SDS/Triton X-100 increases, the interfacial tension and CMC of the blended surfactants were decreased and results in a reducing the size of the latex particles. It was found that the interfacial tension was reduced when the surfactant were blended. By increasing the SDS content, the interfacial tension was reduced, and, at a certain condition, the interfacial tension was reached to an extremely low value to form micro-emulsion and the nano-sized latex particles (80∼110 nm).

박아름,구할본,Park, A-Reum,Jin, En Mei,Gu, Hal-Bon 한국전기전자재료학회 2012 전기전자재료학회논문지 Vol.25 No.4

In general, a photoelectrode in DSSC(dye sensitized solar cell) are fabricated by using the $TiO_2$ (Titanium dioxide) to realize high efficiency and the efficiency of DSSC is affected by the size, the shape and the property of $TiO_2$. We synthesized the crystalline $TiO_2$ by sol-gel method. In spite of many merits, only weakness for the sol-gel method is taking many process times. To solve this problem, we reduced the fabricating processes. The reduced process is the making process that is $TiO_2$ sol to $TiO_2$ powder with including of two heat treatment and two mixing. We could simplify the process by preparing $TiO_2$ sol to $TiO_2$ paste directly. As a result, DSSC fabrication process is simplified and we have obtained the efficiency best result 3.88% with $V_{OC}$=0.71 V, $J_{SC}=8.70\;mA/cm^{-2}$, and FF=62.37%, respectively.

The aim of this study was to examine how customers perceive storytelling at a real local restaurant and to understand how consumption reflects their evaluation by understanding their values. Participants received information from a real local restaurant in the Gangneung area to examine the effects of storytelling and to evaluate their affective attitudes towards local restaurant stories, word-of-mouth intentions, and purchasing intentions using a seven-point Likert scale. A total of 310 consumers were used. A factor analysis was performed to identify consumption value characteristics and factor structure, which consisted economic value, emotional value, and epistemic value. To test whether local restaurant consumers could be classified into homogenous groups based on their consumption values, a three cluster solution was selected, and a Kmeans cluster analysis was performed. As a result, three groups were identified and labeled appropriate for their scores based on each of the consumption values; emotional value-oriented consumers to cluster 1, epistemic value-oriented consumers to cluster 2, and economic value-oriented consumers to cluster 3. An analysis of variance was used to examine the differences in the affective attitudes towards storytelling at the local restaurant, purchasing intentions, and word-of-mouth intentions across the three clusters. The epistemic value-oriented consumers had the highest score for all three variables. In contrast, economic value-oriented consumers had the lowest scores for the three variables. A regression analysis revealed that affective attitudes towards storytelling were significantly affected by these three consumption values. It also showed that positive affective attitudes towards storytelling were associated with higher purchasing intention and word-of-mouth. The significance of this study was to show how customers perceive storytelling at a real restaurant and reflect on their evaluation by understanding their consumption values. As a result, this study examined the potential power of storytelling as an effective marketing communication tool for local restaurants.

박아름 ( Park A Reum ),전종설 ( Chun Jong Serl ) 한국보건사회연구원 2014 保健社會硏究 Vol.34 No.1

본 연구의 목적은 알코올중독자의 대인관계와 자살생각 간의 관계에서 우울이 어떤 역할을 하는지를 파악하는 것이다. 연구대상자는 서울 및 경기 지역에 위치한 정신병원 6곳에 알코올중독 또는 알코올남용으로 입원한 환자 총 151명이며, 다중회귀분석과 Baron&Kenny(1986)의 방식을 통하여 매개효과를 검증하였다. 본 연구의 결과는 다음과 같다. 첫째, 연구대상자들의 자살시도 횟수는 일반성인의 자살 시도율과 비교하면 약 13배 높았고, 자살생각은 평생 유병률보다 약 3배 높게 나타났다. 둘째, 우울과 대인 관계, 자살시도횟수, 음주심각성, 소득, 연령은 자살생각에 직접적인 영향을 미치는 것으로 나타났다. 셋째, 매개효과 검증에서 우울은 대인관계와 자살생각 간의 관계에서 완전매개역할을 하는 것으로 나타났다. 이러한 연구결과를 토대로 알코올중독자의 자살 위험성을 사정하고 개입할 수 있는 실천가들의 교육 및 훈련, 자살 고위험군에 대한 관리체계구축 등과 같은 사회복지영역에서의 실천적 함의를 논하였다. The purpose of this study was to investigate the role of depression in the relationship between interpersonal relationships and suicide ideation among alcoholics. The study subjects included a total of 151 patients hospitalized at six psychiatric hospitals in Seoul and Gyeonggi Province for alcoholism or alcohol abuse. For data analysis, mediating effects were tested with multiple regression analysis and the Baron&Kenny (1986) method. The study findings were as follows: first, the suicide attempt rate of the subjects was approximately 13 times higher than that of non-alcoholic adults, while the subjects` suicide ideation rate was about three times higher. Secondly, depression, interpersonal relationships, number of suicide attempts, alcohol problem, income, and age had direct influence on suicide ideation. Finally, the test results of mediating effects showed that depression had full mediating effect between interpersonal relationships and suicide ideation. Based on these findings, the study discusses practice implications for the field of social welfare such as the need for educating and training practitioners capable of considering suicide risk of alcoholics, as well as the need for tailored intervention programs and their management systems for the high suicide risk group.

박아름 ( Park Ah Reum ),박일우 ( Park Il Woo ) 서울교육대학교 초등교육연구소 2018 한국초등교육 Vol.29 No.2

본 연구에서는 초등학교 2학년을 대상으로 화재 안전을 지도하였으며 화재 안전교육의 직ㆍ간접체험 시간을 확보하고 학생 중심의 수업을 실천하기 위해 거꾸로 교실 수업을 적용하였다. ‘화재 원인과 예방’, ‘화재 대피 방법’, ‘소화기 사용방법’, ‘화재 신고 방법’의 네 영역의 수업을 개발하고 창의적 체험 활동시간을 활용하여 5차시 수업을 실시하였다. 학생들에게는 사전에 학습할 내용의 동영상 주소와 학습지를 제공하고 수업 중에는 화재와 관련된 다양한 영역을 직접 체험해보고 경험할 수 있도록 학생 중심의 활동으로 구성하였다. 수업 적용 후 학생들의 변화된 화재 안전의식 정도를 파악하기 위해 각 영역에 맞는 화재 안전의식 검사를 실시하였다. 그 결과 거꾸로 교실 수업을 적용한 화재 안전교육 후 화재의 원인과 예방 및 화재 대피 방법 영역에서의 화재 안전의식이 향상되었다. 화재가 발생할 수 있는 상황을 찾아 안전하게 고치고 실천할 수 있는 화재 예방 방법을 말할 수 있었다. 수업 후 대피 방법을 표현하는 방법이 보다 세밀해졌으며, 대피 시 주의 점과 주어진 화재의 상황에서의 대피 방법을 구체적으로 설명할 수 있었다. 화재 신고 방법 영역에서는 역할놀이를 통해 화재 신고를 해보며 신고 시 유의해야 할 점을 이해하였고 화재 신고에 필요한 구체적 항목을 추가로 제시할 수 있었다. 거꾸로 교실 수업에서 가장 많이 흥미를 느끼고 재미있었다고 답변한 것은 몸을 직접 움직이는 ‘공 전달하기 게임’과 ‘역할놀이’이었다. 이를 통해 저학년 학생들은 몸을 움직이는 활동에 흥미를 느껴 적극적으로 참여한다는 것을 확인할 수 있었다. 거꾸로 교실 수업을 적용한 화재 안전 수업에 대한 학생들의 만족도가 높은 것으로 조사되었다. 이러한 내용을 바탕으로 초등학교 저학년에서 거꾸로 교실 수업을 활용한 더 나은 화재 안전 지도를 위해 화재 안전을 비롯한 안전 교육의 특성을 고려한 다양한 콘텐츠가 개발되어야 하며, 교사의 역량 강화가 필요하다는 것을 제안한다. The purpose of this study was to apply the flipped learning to the second grade elementary students to teach fire safety. Four areas of classes were developed : " Cause and Prevention of Fire ", " How to Evacuate Fire ", " How to Use Fire Extinguisher " and " How to Report Fire ", and five classes were conducted using the time of creative activities. Students were provided with video URL internet addresses and learning materials to learn in advance, and student-centered activities during the class. After applying the class, we conducted a fire safety consciousness test for each area in order to investigate the changed degree of fire safety consciousness of students. After fire safety classes by applying flipped learning, the cause and the prevention of the fire and fire escape methods in the awareness of fire safety were improved. The method of expressing the evacuation method after the class has become more detailed, and the precautions in the evacuation and the evacuation method in the given fire situation can be explained in detail. In the fire reporting method area, it was also possible to present specific items necessary for fire reporting and to understand the precautions to be taken when reporting a fire through role-play. The students in the lower grades were interested in the activity of moving the body and satisfied with a fire safety classes applying the flipped learning. Based on these findings, it is suggested that various contents should be developed considering the characteristics of safety education including fire safety for better fire safety guidance. Also the capacity of teachers is needed to be strengthened.

1985년 `조-소 국경조약` 분석

박아름 ( Park Ah Reum ) 서강대학교 동아연구소 2017 東亞 硏究 Vol.36 No.2

1985년 북한은 소련과 국경에 관한 조약을 체결하고, 다음해 해양과 관련된 조약을 체결하였다. 본 연구는 1980년대 이뤄진 `조-소 국경조약`의 발생 원인과 배경, 내용, 그리고 영향에 대하여 분석하였다. 이를 통해 사회주의권 붕괴 이전의 동북아 정세와 북한의 대응을 이해하는 데 의미 있는 관점을 제공하고자 하였다. 첫째, 1980년대 동북아의 신냉전이라는 배경 하에 조·소 협력이 높아졌으며, 소련의 제안으로 국경조약이 체결되었다. 둘째, 국경 조약의 내용은 비교적 간단했으며, 체결과정에서 양국이 기존에 갖고 있던 국경선 길이에 대한 차이를 확인하고 국경선과 해양경계의 설정을 명확히 하였다. 한편 조약문 자체에 영공과 영해에 대한 군사적 이용을 포함한 상호 이용 여부는 존재하지 않았다. 셋째, 국경조약이 발생한 시기 북한에서 해양분야의 활성화와 대외군사관계의 확장, 대외무역의 성장이 확인되었다. 이는 `조-소 국경조약`의 원만한 합의가 만들어 준 우호적인 분위기를 바탕으로 이룩된 성과들이었다. 이후 북한은 대(對)중동 미사일 수출 증대와 개도국과의 무역 증대를 통해 사회주의권 몰락의 충격을 완화하였다. In 1985, Democratic People`s Republic of Korea(DPRK) concluded a treaty on the border with the Soviet Union and entered into an agreement on the ocean in the following year. This study analyzed the cause, background, contents, and effects of the `The Border Treaty between Democratic People`s Republic of Korea and the Soviet Union` in the 1980s. Through this, this study was to provide a meaningful perspective to understand the situation of Northeast Asia before the collapse of Communist Nations and DPRK`s response. First, under the background of new cold war era in Northeast Asia in the 1980s, the cooperation of DPRK and the Soviet Union was enhanced and the border negotiations were concluded with the proposal of the Soviet Union. Second, the contents of the border treaty were relatively simple and identified the difference in the length of the border between the two countries in the process of conclusion and clarified the setting of the border line and maritime boundary. On the other hand, there was no information on mutual use including military use in the airspace and territorial waters in the Treaty itself. Third, during the period when the border treaty occurred, the activation of the maritime sector, expansion of foreign military relations, and growth of foreign trade were identified in DPRK. These were accomplished based on the favorable atmosphere created by the amicable agreement of `The Border Treaty between Democratic People`s Republic of Korea and the Soviet Union` for DPRK. Since then, DPRK has eased the impact of the collapse of Communist Nations through increased exports of missiles toward Middle East and increased trade with developing countries.
