The purpose of this study is to improve and present the convection experiment box to understand the principle of the land and sea breeze effectively and to apply it to science lessons. Based on a survey of teachers' perceptions of convection experiments, we have improved the convection experiment box in three aspects: the structure of the convection box, the visualization of the convection flow, and the application of the inquiry functions. For the verification of the revised experiment, 84 fifth graders of four classes in Seoul were applied to two classes for experimental group and two classes for comparative group to evaluate the usefulness of the improved convection experiment box and the effectiveness of teaching and learning of convection. The results showed that the students’understanding level of the land and sea breeze in the experimental group was significantly higher than that in the comparative one. Both teachers who observed the lessons and the students responded to the questionnaire asking the usefulness of the improved convection experiment box that the improved experiment box was more effective than that in the current 2009 revised textbook. The improved experiment box can help students understand better the land and see breeze principle. Also, teachers expect that this improved experiment box can increase students interest and use inquiry skills as well as be utilized with ease in the lessons. 본 연구는 해륙풍 원리를 효과적으로 이해할 수 있도록 대류실험상자를 개선하여 제작하고, 이를 수업에 적용하는 데에 목적이 있다. 연구를 위해 대류실험에 대한 교사들의 인식을 조사하고, 이를 바탕으로 대류실험상자의 구조, 대류 흐름의 시각화, 탐구 기능의 활용의 3가지 측면에서 대류실험상자를 개선하였다. 개선된 실험의 효과를 검증하기 위해 서울 소재 초등학교 5학년 4개 학급 총 84명을 각각 2개의 실험반과 비교반으로 선정하였고, 해륙풍 관련 개념 검사와 실험에 대한 설문조사를 실시하였다. 학생들에게 적용한 결과, 실험반의 해륙풍 관련 개념의 이해 정도가 비교반에 비해 유의하게 높았다. 개선된 대류실험상자에 대한 평가를 묻는 설문 조사에서 학생들은 해륙풍 원리 이해에 효과적인 것으로 조사되었다. 참관 교사들은 학생들의 흥미, 탐구 기능 활용 정도, 준비의 편리성 등의 측면에서 개선된 실험이 효과적이라고 응답하였다.

Purpose : Stabilization exercise and respiratory muscle training are used to train trunk muscles that affect postural control and respiratory function. However, there have been no studies that combine stabilization exercise and respiratory muscle training. The purpose of this study is to investigate effects of stabilization exercise with and without respiratory muscle training on respiratory function and postural sway. Methods : Fifteen healthy adults were recruited for this experiment. All the subjects performed stabilization exercise with and without respiratory muscle training. For stabilization exercise with respiratory muscle training, the subjects sat on a gym ball wearing a stretch sensor. The subjects inspire maximally as long as possible during lifting one foot off the ground, alternately for 30 seconds. The stretch sensor was placed on both anterior superior iliac spine (ASIS), and the stretch sensor was used to monitor inspiration. For stabilization exercise without respiratory muscle training, the subjects sat on a gym ball and lifted one foot off the ground, without respiratory muscle training. Kinovea program used to investigate postural sway tracking during exercise. The maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP) were measured using a spirometer to investigate changes of respiratory muscle strength before and after exercise. A paired t-test was used to determine significant differences postural sway tracking, MIP, and MEP between stabilization exercise with and without respiratory muscle training. Results : There were significantly lower a distance of postural sway tracking during stabilization exercise with respiratory muscle training, compared with stabilization exercise without respiratory muscle training (p<.05). The MIP and MEP were significantly increased after stabilization exercise with respiratory muscle training compared with before stabilization exercise with respiratory muscle trianing (p<.05). Conclusion : The results of this study suggest that stabilization exercise with repiratory muscle training would be recommended to improve postural control and respiratory muscle strength.

KOH와 CO₂ 활성화에 의한 카본에어로젤의 기공특성 및 EDLC 전극재로서의 전기화학적 특성

서혜인(Hae Inn Seo),김상길(Sang-Gil Kim),정지철(Ji Chul Jung),김명수(Myung-Soo Kim) 한국고분자학회 2016 폴리머 Vol.40 No.4

카본에어로젤(CA)의 KOH와 CO₂ 활성화를 진행하여 기공특성 및 전기화학적 특성에 끼치는 영향을 조사하였다. KOH로 활성된 CA는 높은 비표면적과 높은 EDLC 전극 비용량을 나타냈지만, 미세기공보다 중기공이 더 발달하였고, 고전류에서 상대적으로 비용량의 감소폭이 크며, 활성화과정에서 결정성을 대부분 잃어버려 전기전도도가 낮았다. 한편, CO₂ 활성화된 CA는 KOH 활성화된 CA에 비해 1/2 수준의 비표면적을 갖지만, 80% 전후의 비용량을 나타냈다. CO₂ 활성화된 CA의 기공분포는 1 nm 근처의 미세기공이 상대적으로 더 많이 발달하였고, 적절한 기공구조로 인해 고전류에서 용량의 감소폭이 상대적으로 작았으며, 활성화 후 결정성을 유지하여 전기전도도가 상대적으로 높았다. CO₂ 활성된 CA의 전기화학적 특성을 향상시키기 위해 활성화온도를 850에서 1000 ℃로 변화하였을 때, 활성화온도의 증가에 따라서 비표면적과 비용량이 증가하였다. 하지만, 활성화수율 및 단위면적당 비용량을 고려하여 최적의 활성화온도는 950 ℃로 결정하였다. A resorcinol-formaldehyde (RF) carbon aerogel (CA) was activated with KOH and CO₂. The effect of KOH and CO₂ activation on the textural properties and the electrochemical properties of CA was investigated. The KOH activated carbon aerogel (KOHACA) had higher specific surface area and specific capacitance as an electric-double-layercapacitor (EDLC) electrode than the CO₂ activated carbon aerogel (COACA), but the COACA exhibited better electrochemical performance at a high current than the KOHACA. The COACA had more uniform pore structure of around 1 nm and higher electrical conductivity due to increased micro-crystallinity as compared to the KOHACA. As the activation temperature increased in the range of 850~1000 ℃, the specific surface area and specific capacitance per mass of COACA increased. However, the optimal activation temperature was determined as 950 ℃ considering activation yield and specific capacitance per area.

서기원 소설 연구 : 『혁명』을 중심으로

서혜지 배재대학교 주시경교양교육연구소 2019 대학교양교육연구 Vol.4 No.1

서기원은 한국전쟁체험에서 나온 50년대의 시대성을 표현한 작가이다. 서기원의 소설은 단순히 전쟁의 현장을 전면으로 내세우기보다는 그 시대를 살아온 개인의 삶을 다루고 있 어 주목할 만하다. 전쟁이라는 상황에 직면한 개인의 의식과 행동에 초점이 맞추어졌던 그의 전후 소설과 는 달리 60년대 역사소설에서는 그 역사를 이끌어 가는 민중에 관심을 두고 있기도 하다. 따라서 본고에서는 서기원의 전기와 후기 소설의 분기점이라 할 수 있는 혁명을 토대 로 그 시대의 현실인식과 그의 문학관을 함께 살펴보았다. 또한 ‘동학’이라는 ‘혁명’을 통해 작가가 당대현실에서 말하고자 하는 바가 무엇인지 이 시대에 주목해야 할 점이 무엇인지 에 대해서 분석하였다. Seogiwon is a writer who expresses the times of the 50s from the Korean War experience. It is noteworthy that Seo Gi-won’s novel deals with the life of an individual who lived in the era rather than merely putting the battle scene at the foreground. Unlike his post-war novels, which focused on the consciousness and actions of individuals facing the situation of war, the 60’s history novels have also focused on the people who lead the history. Therefore, in this paper, based on the "revolution" which can be considered as a turning point of the first and second novels, In addition, through the ‘Revolution’ called ‘Donghak’, I analyzed what the artist is trying to say in the current reality and what should be noted in this era.

교양교육으로서의 문학읽기 : 방현석의 「내일을 여는 집」을 중심으로

서혜지 배재대학교 주시경교양교육연구소 2017 대학교양교육연구 Vol.2 No.2

방현석은 1980년대 노동소설의 중심에 있는 작가이다. 그가 쓴 노동소설은 그 시대 노 동자들의 실상을 면밀히 파악할 수 있는 중요한 연구자료이다. 민중을 역사의 주체로 파악 하고, 노동 현장의 부당함과 열악함을 바꿀 사람은 그 누구도 아닌 노동자 자신들이라는 사실을 노동소설은 말해 줄 수 있다. 노동자들이 부당함을 깨닫고 앞으로 나아가야만 현실 을 변혁할 수 있는 것이다. 「내일을 여는 집」에서 보이는 현실은 노동자들을 그저 하나의 도구로써만 사용하는 자 본가들과 이에 맞서는 노동자들의 대립이다. 이들의 투쟁의 목적은 월급을 더 받기 위한 것만이 아닌 비인격적인 처우에 대한 투쟁으로 발전한다. 투쟁과정과 갈등을 겪는 과정을 통해 의식이 성장하는 노동자들은 미래에 긍정성을 부여하기도 한다. 본 논문에서 다룬 소 설은 노동자 계급의 입장에서 삶과 현실을 그린 문학작품으로 노동자들의 부당함은 노동자 들의 손으로 해결해야 성공할 수 있고 가치가 있는 일이 된다는 발전하는 의식에 대해 분 석하였다. The “A House that opens tomorrow” by Bang Hyun Suk has a process of struggle for reinstatement after being dismissed after claiming the unfairness of the capitalists. Through this work, they show what they want and what they are transforming. Through this novel, Bang, Hyun Seok shows that the liberation movement of the working class throughout Korea should solve the broader democratic tasks in a comprehensive way. In the course of struggle to transform the reality, we saw a meaningful struggle by seeing the process of knowing that the master of history is the workers themselves.

가난한 사람들의 유랑과 가족의 해체 : 공선옥의 『유랑가족』을 중심으로

서혜지(Seo Hye-ji) 韓國批評文學會 2009 批評文學 Vol.- No.34

A modern person is a life of a consumption and corresponds an order of a capital. A richer people can stand up in the center of a world, because the money is a way to actualize a desire for surviving in the modern capitalism society. The poor people always possess themselves of the outside from a center of a minority to the outside in the orderly moving society by the capital. The work's characters that this study treats are treated distantly by the society and live a circumstance of a society. A family who staying in the outside world is risky. The nomadic family follows up the poor's trace through his sight of a documentary photographer 'Han'. Due to poverty, the family aren't dissolved and aren't settled down. “The poverty isn't guilty. But poor people are a nomadic people for wandering who doesn't prepare a site of a life.” As the writers would say, poor people live a reality that are forced out of the outside society because of an underdeveloped area's development according to industrialization. This work shows various ways that money make poor people getting out of the present's situation though their life separately differs in the world which is estimating everything by money. Because of a poverty, women passed over the boundary and family's boundary. Because People don't free themselves from the family's dismantlement and poverty's the yoke, they didn't settle down on the rove. So therefore this work looks into a meaning of the poverty through a wondering characters in this age. Most people think that poor people have no regard for other people's pain, giving way in the edge city. But a writer states that this world have a little hope. Then the purpose of this study is analyzing together about an affirmative concept presenting a writer.

2-furoyl kraft lignin-polypyrrole copolymer mats by surface doping with iodine were prepared by electrospun 2F-KL/PPy copolymer. The 2F-KL/PPy copolymer were synthesized by interfacial polymerization of pyrrole with acylated 2-furoly kraft lignin. The structural properties were analyzed by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscope (SEM) and thermogravimetric (TGA) analysis. In addition, electrochemical properties of the 2F-KL/PPy were evaluated by cyclic voltammetry test using coin cell. The iodine-doped 2F-KL/PPy electrode coin cells exhibited specific capacitance of 34 F · g<SUP>-1</SUP> at a scan rate of 2 mV · s<SUP>-1</SUP>. The specific capacitance of iodine-doped 2F-KL/PPy electrode coin cell was higher than that of 2F-KL/PPy electrode without doping iodine. According to the electrochemical properties, the iodine-doped 2F-KL/PPy copolymer could be suitable for energy storage device electrode. However, the specific capacity of iodine-doped 2F-KL/PPy and 2F-KL/PPy electrode decreased gradually at a high scan rates. Since water-soluble electrolyte could not react with the electrode, the specific capacity of the coin cell decreased.

서혜지(Hye-Ji, Seo) 어문연구학회 2008 어문연구 Vol.58 No.-

Every man is difficult to free oneself from an age and class's cultivation. So writers work each individual which existence is disclosed historically as a text. As Each individuals is small dots, Each individuals buried alive historically. But Each individuals maintained the axis of history. Like this, characters who took charge of the axis of history expressed a section of various daily life in Iee-hyun Jung's Today a Lie : a book of stories. A women character leaves a false afternote in internet site and A divorce appear in this story : He imagines dropping dog which divorced former wife keeps. Also in the past confining dangerous fille appears. As their lives are unusual, various as they adapt themselves to distorted society and they live variously. As far as I can remember, lively experience is used by stamped memory's layout and memory's rediscovery. This study manages Iee-hyun Jung's story Today a Lie. This story appears those characters : at the same time by the subject of consumer and consumer target, they take up oneself position that young generation's feature and fleshly outlook on life. Also they show a communication in capacity's relation which run deep between society, individual and men. Also this story that reveals modern problem : unemployment, non-regular worker, poverty variously shows a personal aspect of the capitalism society. For such an aspect and fetishism of the capital, family and personal everyday affairs keep an outward calm. But this study bitterly reappear that they keep shaking form a deep root. This study examines how this story recognizes the reality and daily life for a past experience which remembers each individual character in the story. Also this study examines how each individual persons are neglected in the society for a communication incapacity's relation and fetishism of the capital.
