Papert [17] introduced the LOGO environment in which we make a curve using LOGO commands (FORWARD, ROTATE). We call this geometry as turtle geometry. This environment has influenced many researchers and designers of computers and mathematics education. But the curve that we can make using LOGO command is elementary or too difficult. Polygon and circle is elementary and making other curves is difficult. In this paper, we introduce the method of drawing some other curves mediating new command. First, we study epicycloid and hypocycloid in the historical and the physical context. And we introduce the method of making epicycloid and hypocycloid using vector addition. Next we study the polygon patterns of this curve. Finally, we extend the method for making more general curve and we improve the computer environment using this metaphor.

Recently, various geographic information systems have been used based on spatial information of geographic information systems. Accordingly, it is essential to produce a large-scale map as a small-scale map for various uses of spatial information. However, maps currently being produced have inconsistencies between data due to production timing and limitations in expression, and productivity efficiency is greatly reduced due to errors in products or overlapping processes. In order to improve this, various efforts are being made, such as publishing research and reports for automating domestic mapping, but because there is no specific result, it relies on editors to make maps. This is mainly done by hand, so the time required for mapping is excessive, and quality control for each producer is different. In order to solve these problems, technology that can be automatically produced through computer programs is needed. Research has been conducted to apply the rule base to geometric generalization. The algorithm tolerance setting applied to rule-based modeling is a factor that greatly affects the result, and the level of the result changes accordingly. In this paper, we tried to study the effectiveness of mapping according to tolerance setting. To this end, the utility was verified by comparing it with a manually produced map. In addition, the original data and reduction rate were analyzed by applying generalization algorithms and tolerance values. Although there are some differences by region, it was confirmed that the complexity decreased on average. Through this, it is expected to contribute to the use of spatial information-based services by improving tolerances suitable for small-scale mapping regulations in order to secure spatial information data that guarantees consistency and accuracy.

Kim You Jung was a stammerer to be internalized. His work was a better communicative way than a stammerer`s speaking word. As for him, the novel was a kind of way to express his thought about the outer world, His stammer was potential in his novels. His novel had many kinds of noises, many strange vocabularies and fluency. Kim You Jung`s stammer is a kind of way to make fluency and humor in his works. The clean imagination for fluency was expressed by a wordplay, laugh and humor which could have been the identity of Kim You Jung`s novel. The potential for the handicap over the stammer could have been expressed through a person to be ordinary and comprehensive, not a person to be handicapped and individual in his works. These interested wordplay and humorous conversation were expressed and made unique moody in his works. The writing for curing his handicap, stammer has been a way of comforting and diverting readers` mind by these days.

OECD 교육지표와 PISA를 이용한 수학 수업 시간 국제 비교

김화경(Kim, Hwa Kyung),송민호(Song, Min Ho),정인우(Chung, In Woo),최인용(Choi, Inyong) 이화여자대학교 교과교육연구소 2021 교과교육학연구 Vol.25 No.1

수업 시간의 양은 교사의 수업과 평가, 학생의 학업 성취에 영향을 주는 중요한 요소 중 하나로 교육과정이 현장에서 수업으로 잘 구현되기 위해서는 적당한 수업 시간이 확보되어야 한다. 본 연구에서는 OECD 국제 지표를 이용하여 우리나라 수학 수업 시간이 국제적으로 어느 정도 수준인지 비교하였다. 그리고 PISA 자료와의 연계를 통해 국가가 보장하는 의무 수학 수업 시간과 수학 성취도 사이의 상관관계를 살펴보았다. 분석 결과, 우리나라는 OECD 소속 23개국 중 초등 저학년, 초등 고학년에서 수학 수업 시간이 가장 적었으며, 중학교에서는 헝가리 다음으로 수업 시간이 적었다. OECD 평균은 학년이 올라갈수록 수학 수업 시간이 감소하지만 우리나라는 정반대의 경향을 나타냈고, 초등 저학년, 초등 고학년, 중학교의 수학 수업 시간은 각각 OECD 평균 대비 64%, 70%, 81% 수준 밖에 되지 않았다. 개별 국가의 의무 수학 수업 시간은 수학 성취도 평균과는 정적 상관을 나타냈으며, 1수준 미만 비율과는 부적 상관을 나타냈다. Instruction time is one of the important factors affecting the teaching and evaluation of teachers, and academic achievement of students. For successful implementation of curriculum in classes, adequate instruction time should be secured. In this study, the researchers compared the degree of mathematics instruction time in Korea to other nations across the world, using OECD education indicators. In addition, the correlation between the compulsory mathematics instruction time guaranteed by the country and mathematics achievement was examined, based on PISA data. The result of the analysis showed, among 23 OECD countries, Korea has the lowest instruction time for mathematics in elementary schools and the second lowest in middle schools. It is the OECD average that mathematics instruction time decreased as students advanced on to higher grades but Korea showed the opposite trend. Mathematics instruction time in the lower elementary, upper elementary, and middle schools in Korea is only at 64%, 70%, and 81% of the OECD average, respectively. The compulsory mathematics instruction time of each country indicated a positive correlation with the average of mathematical performance, and negative correlation with the ratio of below level 1.

한국사상(韓國思想)(문학(文學)) : 바리공주 신화의 연구

김화경 ( Hwa Kyong Kim ) 한국사상문화학회 2009 韓國思想과 文化 Vol.46 No.-

본 연구는 진오귀굿에서 구송되는 바리공주 신화에서 바리공주가 어떤 신격을 가지고 있으며, 왜 그녀가 무조신이 되어야만 했던가? 그리고 이 신화가 진오귀굿에서 구송되는 이유는 무엇인가 하는 문제를 구명하기 위해서 마련되었다. 그리고 이런 문제의 해명을 위해서 이 신화가 여신 신화라는 것을 전제로 하였다. 이런 전제로부터 문제를 해명하려고 한 이유는 여신에 대한 숭배가 남신의 그것보다 앞서 형성되었다는 종교학에서의 연구 성과를 받아들여, 바리공주 신화도 이와 같은 전제를 충족시키고 있으므로 그 역사가 매우 오래 되었다는 것을 증명하기 위해서였다. 다시 말해 바리공주 신화가 비록 구전되는 것이기는 하지만, 상당히 이른 시기에 한국에 전래되었다고 보았다는 것이다. 그리고 이렇게 일찍 한국에 들어온 이 신화는 지모신 사상을 바탕으로 하고 있기 때문에, 바리공주가 농경신·지모신적 성격을 지녔을 것이라는 상정을 하였다. 또 바리공주가 저승에 가서 부모를 살려내는 약수를 구해온 것은, 수메르의 이난나 신화와의 비교를 통해 원래부터 이 신화가 가지고 있는 것이라는 추정을 하였다. 이런 추정은 이 신화가 불교나 도교의 영향을 받아 만들어졌다는 종래의 연구 성과를 재고하기 위한 것이었다. 또 무당이 저승에 가서 사람을 살려내는 약수를 구해온다는 것은 무당이 수행하는 역할의 한 단면을 표현한 것으로 보았다. 그러면서 영웅담의 구조적 모델로 된 바리공주 신화가 진오귀굿에서 구송되는 것은 무조신인 바리공주로 하여금 죽은 사람의 영혼을 좋은 곳으로 천도하지 않을 수 없게 만들기 위한 수단이라는 사실을 밝혀냈다. The aim of this thesis is to clarify what kind of divinity Princess Bari has in the myth of Princess Bari which is recited in Jinokwi-gut, why she becomes a founder of shaman, and why this myth is recited in Jinokwi-gut. To elucidate such questions, the premise that this myth is a goddess myth is set forth. The reason this study is to elucidate the questions from the premise is that this study accepts the research achievement of Religious Studies, which is, the goddess worship is formed more earlier than the god worship. And also as the myth of Princess Bari suffices the premise, it is possible to prove that the myth of Princess Bari has a very long history. In other words, even if the myth of Princess Bari has been handed down orally, it was introduced in Korea in much earlier period. As the myth of Princess Bari which was introduced in such early period is based on the thoughts of Earth Mother, it can be possible to have a presumption that Princess Bari has a quality of farming god·Earth Mother. And also, through the comparative study between the Inanna myth of Sumer and the story that Princess Bari goes to the Underworld, and brings the Yaksu, it is suggested that originally the myth of Princess Bari has the story. This suggestion is for reconsideration of the previous study achievement that the myth of Princess Bari is made up under the influence of Buddhism or Taoism. And then, the story that the shaman brings the Yaksu which can save a person from death is considered as an expression of a phase of the shaman`s activities. And it is found out that the recitation of the myth of Princess Bari, which becomes a structural model of heroic episode, is a method to get the founder of shaman, Princess Bari, to transfer the soul of the dead to a better place.

의례적 행위와 삶의 진지함: 비트겐슈타인의 인류학적 사유에 대한 고찰

김화경 ( Kim Hwa-kyung ) 한국동서철학회 2016 동서철학연구 Vol.0 No.82

본 논문은 비트겐슈타인의 1930년대 초기의 저술들을 중심으로 그의 `인류학적 고찰방식`이라는 하는 새로운 사유의 흐름을 다루고 있다. `인류학적 고찰방식`은 철학적 주제나 문제들을 언어와 세계 사이의 논리적인 형식만으로 다루던 방식에서 벗어나서 인간의 삶과 관련된 모든 방면에서 다루는 것을 의미한다. 이런 점에서 비트겐슈타인의 인류학적 사유는 철학적 문제들에 대한 통시적, 다학문적, 통합적, 재생산적인 사유의 방식으로 문화비평으로서의 비트겐슈타인의 철학을 자리매김하는 새로운 전망을 제시한다. 비트겐슈타인은 언어로 표현될 수 없는 문제들은 그 문제들이 뿌리를 내리고 있는 언어 이전의 삶과의 연관성 속에서 고찰되어야 하고, 이런 고찰을 통해 말할 수 없는 것들은 인간의 본능적 행위 안에서 드러날 수 있음을 밝힌다. 따라서 우리에게 필요한 것은 전(pre)-언어적 행동방식과 삶의 문제들 사이의 연결고리들의 발견이다. 이러한 연결고리들은 주술이나 의례적 행위로 표현되는 원초적 반응, 즉 상징들이다. 의례적 행위는 그것을 수행하는 공동체 안에서 그 `의미심장함`이 공유됨으로써 설명의 대상이 아닌 세계관으로 주어진다. 이때의 `의미심장함`은 `놀라움에로 깨어남`이란 특별한 인간 정신을 요청한다. 세계와 인간의 삶 사이의 소통의 다리를 놓는 `놀라움에로 깨어나는 인간 정신`은 비트겐슈타인의 인류학적 사유의 연구 정신이며 그가 생각하는 진정한 학문의 정신이라고 할 수 있다. 따라서 비트겐슈타인의 인류학적 사유의 여정은 인간 조건으로서의 세계와 삶의 관계맺음이라는 삶의 진지함을 찾아 가는 심도 깊은 철학적 성찰의 과정이다. This essay on Wittgenstein`s anthropological consideration uncovers a new train of thought by Wittgenstein with special emphasis on his writings in the early 1930s. The study on anthropological consideration escapes from a conventional way of dealing with a logical form between language and the world; it discusses philosophical problems from all aspects related to the lives of human beings. The anthropological thinking by Wittgenstein is a way of thinking which is diachronic, multidisciplinary, integrated, and reproductive, and it suggests to reconsider the philosophy of Wittgenstein as a cultural criticism. According to Wittgenstein, issues that cannot be expressed by language must be thought about in their relation with live as it exists before language. Through this kind of consideration the unspeakable can be revealed in instinctive actions by human beings. Therefore, in order to understand how language and the world is related, we have to discover connections between pre-linguistic modes of behavior and the issues in our lives. These connections are expressed by magic and ritual, in other words, by symbols. The essay demonstrates that rituals appear as a view of the world as their `meaningfulness` is shared within the community where they are performed. The `meaningfulness` demands a special human spirit which is called `awakening to wonder.` `Awakening to wonder` takes charge of the role as a way by which human beings can communicate with the world `which cannot speak`. For that reason, `awakening Human Spirit to wonder` may be called the core of Wittgenstein`s studies on anthropological thinking and the spirit of true study that he thinks of. In this regard, Wittgenstein`s voyage of anthropological thinking culminates in a deep philosophical introspection of the seriousness of life: the relationship between world and life as a human condition.

논문(論文) : 안용복의 정문에 대한 연구

김화경 ( Hwa Kyong Kim ) 대구사학회 2012 대구사학 Vol.107 No.-

This paper aims to refute the content of Japan side material paper of 「A reiew on Ahn Yong-bok Event」 which has been delivered on Dec.02, 2011 by Ikeuchi Satoshi((池內敏) at the ``A Symposium for Ulleungdo·Dokdo in view point of Korea·Japan`` in Ahn Yong-bok Research Center of Daegu Hanui University. Ikeuchi assumed that Ahn Yong-bok`s document was aimed to protest the unfair treatment for him by Dottori regional government when Ahn Yong-bok was abducted by fishermen of Oya Family(大谷家) in 1693 and transferred to Tsushima. However, this paper assumedmen Ahn Yong-bok`s protest for ``Ulleungdo belonging`` issue at Dotori regional government based on the records 「A Record Concerning One Choseon Ship Landed(朝鮮舟着岸一卷之覺書)」 and 『Gosaihunitski(Diary of Central Government Office(御在府日記)』 from materials of the regional government. This assumption was proved it`s validity by the article about discussion on criminal of Ahn Yong-bok at 『Seungjeong-won Diary(承政院日記)』 on September 27, 1696. Also this paper assumed one more matter which was raised by Ahn Yong-bok at Dottori regional government was ``Ulleungdo Belonging`` and ``False Action of Tsushima Governor(對馬島主) Concerning Reduction of Present Quantity and Question of An Intention to Acquire Ulleungdo``. To say, Dottori tried to reduce quantity of present from Chosen government to report to Edo Bafuku by gaining interest and distorting Bafuku Order to acquire Ulleungdo. Though this Ahn Yong-bok`s document matter was known to Tsushima but it is a vague issue why there is no more record still. This issue should be proved by more active material collection and obvious verification of it.

가야문화축제의 관광 특성과 활성화 방안에 관한 연구

김화경 ( Hwa Gyeong Kim ),최화열 ( Hwa Yeol Choi ) 한국사진지리학회 2015 한국사진지리학회지 Vol.25 No.1

본 연구는 김해 지역의 지역축제인 가야문화축제를 대상으로 그 경남의 가야축제, 김해 가야축제의 관광특성을 사진을 이용하여 고찰하였다. 가야문화축제는 역사적 중요성에 비해 상대적으로 일반인들의 관심에서 벗어나 있던 고대 가야시대에 대한 관심을 부각시켜 제 4제국인 가야 역사적 중심지인 김해를 널리 알리는 계기를 마련했다. 가야문화축제가 경남의 문화축제로서 뿐 아니라 전국민의 지지를 얻는 관광문화축제로 자리매김하고 국제적 문화축제로 성장하기 위해서는 축제의 양적 확대와 함께 질적 성장을 이루어야 하며, 적극적 홍보와 가야문화권 연계 프로그램 전략을 도입할 필요가 있다. 따라서 본 연구는 김해 가야문화문화축제의 관광 특성을 살펴보고 이를 활성화 할수 있는 방향을 알아보고자 한다. This study, mainly based on Gaya Cultural Festivals especially in Gimhae and Kyungnam area, researched and analyzed Tourism characteristics by using the photos of the area. Given the historic importance of the area, Gaya Cultural Festival is a bit away from the public attention. Boosting an interest in the area through highlighting Gaya as an ancient historical center can be a big opportunity for the locals. To make Gaya Cultural Festival not only for Kyungnam province but also as an international Festival as well as a national one, it is very important to tremendously pursuit both qualitative and quantitative growth with the expansion of the festival at the same time. In addition, it is very necessary to strategically introduce the associated Gaya Cultural program and actively promote the festival.
