In Sasang Constitutional Medicine, pine trees have been used as medicines for Taeyangin and a pine-nuts tree for Taeumin. However, there has been some misunderstandings in interpretation as the Koreans referred to back(栢) as pine-nuts tree as well as cheukback(측백) tree. Also, we have disputed over how to translate songback(松栢). Regarding this dispute, 1 came to the following conclusion based on a research with exactitude. 1. Songja (松子), Songjain(松子仁), Songsil(松實) means Pinus Koraiensis(잣), not a pine .one. 2. Backja(栢子) is a fruit of Cheukback(측백) tree, not of a pinus koraiensis(잣). 3. Some part of 'yulsunjun(列仙傳)' quoted to explain pine-nuts in Bonchogangmok(本草綱目) was misrepresented. 4. In regard to the record that a court lady of Chin(秦) Dynasty lived for bundle of years, Galhong(葛洪) made a mistake by saying that she took pine needles and a Pinus Koraiensis in 'Pobakja(抱朴子)', while saying that she took pine needles and leaves of Cheukback(측백) tree in 'Joohoobigeupbang(　後備急方). Also He made a mistake by saying that took pine needles and leaves of cheukback(측백) tree in Bonchogangmok(本草綱目). 5. Songback(松栢), which was referred to in the Analects of Confucius(論語) and the historical annals(史記), should be understood as an old pine tree with a hard quality of the lumber and evergreen, .rather than 'a pine tree and a pine-nuts tree' or 'a pine tree and Cheukback(측백) tree'. 6. Although 'Songback(松栢) mentioned in a book on medicine were sometimes considered as 'a pine-nuts tree' and 'Cheukback(측백) tree' or 'a pine tree and .Cheukback(측백) tree,' it should be regarded as an old pine tree in most cases.

이 연구에서는 고등학교 과학 교과서와 화학 II 교과서에 제시된 황산에 대한 설명을 분석하고, 화학교육을 전공하는 예비 교사 10명을 대상으로 황산에 대한 인식을 조사하였다. 연구 결과, 고등학교 과학에서 황산이 물에서 2개의 $H^+$와 1개의 $SO_4{^{2-}}$로 해리하는 내용을 제시한 교과서들이 많았다. 그러나 황산은 일차 해리를 하여 1개의 $H^+$와 1개의 $HSO_4{^-}$로 존재하므로 이러한 오류는 수정될 필요가 있다. 화학 II 교과서에서는 황산의 단계별 이온화를 언급하였으나, 일부 교과서에서는 과학 교과서와 같은 오류를 가지고 있었고, 일차 해리된 $HSO_4{^-}$의 경우 약산임에도 불구하고 산의 세기가 센 것으로 표현하였다. 황산에 대한 예비교사들의 사고를 조사한 결과, 95% 황산 수용액과 15% 황산 수용액에 존재하는 입자의 형태를 제대로 이해하지 못하는 경우도 있었으며, 이들의 사고는 고등학교 때의 학습으로부터 영향을 받은 것으로 나타났다.

이 논문에서는 운전자(남)와 동승자(여)가 탑승하여 하천 둔치의 공원에 정차 중 차실 내에서 폭발사고가 발생한 승용차에 대해 폭발사고 원인을 분석하였다. 폭발사고가 발생한 직후 운전자와 동승자가 화상을 입고 119구급대에 의해 병원에 이송될 때는 119구급대원에게 시너를 뿌려놓은 상태에서 운전자와 동승자가 다투는 중에 폭발사고가 발생하였다고 진술하였는데, 며칠 경과한 후부터 운전자와 동승자는 플라스틱 병 속에 들어 있던 휘발유가 엎질러져 시거 잭으로 흘러들어가서 시거 잭을 빼려다가 시거 잭을 실수로 눌러서 폭발사고가 발생하였다고 주장하였다. 실수로 인해 폭발사고가 발생하였다면 자동차보험금을 지급받을 수 있고 고의에 의해 폭발사고가 발생하였다면 보험금 지급이 안되므로 폭발사고의 원인이 고의에 의한 것인가 실수에 의한 것인지가 쟁점이 되었다. 폭발한 승용차에 대한 구체적인 조사 분석과 운전자 및 동승자의 진술에 대한 화재과학적 분석을 통해 이 자동차 폭발사고는 운전자의 고의에 의해 발생한 것임을 입증하였다.

High temperature and natural sun light are considered as the core conditions for high quality and large quantity of Phellinus baumii production. However still now on there has been a mistake of excessively cutting off the natural light by spreading the closing nets on the mushroom cultivating house. For an example there are many houses where the closing nets under the roofs be extended to cover the sides of the houses, which way prevents the mushrooms in the houses from receiving sufficient natural sun light and getting the temperature sufficiently to grow so that the quantity and quality of the produced mushrooms are lowered even though the mushrooms can grow in those conditions. In order to avoid this mistake, the closing nets must be placed on the roofs of the houses only without dropping them to cover the sides. Further more when the closing nets are placed triply at the beginning stage of Phellinus baumii's growth in the house, the nets restrain the internal temperature of the house going up and intercept the natural bright light flowing into the house so that the growing tardiness occur to the Phellinus baumii. Therefore the roof only must have been covered by the closing net for 65% cutting off the light until May, and then covered by double folded the net for June, triple folded the net for July and August, double folded the net for September, and the single net for October. When the ventilation in the house has been maintained until the house tightly balloon out through controling lifting force of internal air, the Phellinus baumii can grow well while the bed logs themselves aren't dried out. Marketing is also very much important as well as increasing quality and quantity of Phellinus baumii production.

Purpose - This paper examines the admissibility of restitution as the legal consequence where a contract is frustrated under the Law of Reform (Frustrated Contracts) Act 1943 in comparison with Korean Civil Code (KCC). In order to provide practical guidelines and advice regarding choice of and application of law for contracting parties in international trade, the paper comparatively evaluates requirements and the scope of restitution under the Act 1943 and KCC. Design/methodology - This paper executes a comparative study to analyze whether the parties may claim restitution of money paid or non-money benefit obtained before or after the time of discharge under English law and KCC. To achieve the purpose, it focuses on the identifying characteristics of each statute, thereby providing guidelines to overcome difficulties in legal application and interpretation as to restitution as the consequence of frustration. Findings - Under English law, the benefit may be restituted according to Art 1943 or the common law rule, mistake of fact or law. Under the KCC, restitution is considered based on the principle of the obligation to recover the original obtained regardless of the time when the benefit is conferred. Whilst Act 1943 does not require careful analysis of the grounds of restitution, requirements to justify restitution according to the principle of unjust enrichment, mistake of fact or law, and the KCC should be met. Meanwhile, the KCC may provide more opportunities to award restitution because it does not require the burden of proof related to the defendant's good faith, unlike the principle of unjust enrichment. Originality/value - Where the contract is frustrated by the effect of COVID-19, one legal issue is a consequence of frustration. Therefore, this paper analyzes requirements and the scope of restitution under English law as compared with the KCC in a timely manner. It provides contracting parties with practical guidelines and advice to reduce unpredictability when they choose the governing law in a contract.

본 논문의 목적은 K대학 학생들의 성별에 따른 젠더 관련 이슈에 대한 인식 차이를 살펴보고 대학 교육 체계 내에서의 대응 방안을 제안하는 것이다. 연구 결과 첫째, 남성은 여성에 대한 구조적 차별은 존재하지 않고 역으로 남성이 차별 받고 있다고 생각하는 반면, 여성의 경우 이와는 반대되는 인식을 보이고 있다. 둘째, 여성의 노력 정도 및 소득이 낮은 이유, 취업 후 업무능력등에 대해서도 남녀는 유의미한 인식 차이를 나타낸다. 셋째, 남성들의 경우 여성에 비해 페미니즘에 대해 비우호적인 태도를 보이고 있다. 넷째, 남성들이 여성 할당제와 페미니즘에 대해 적대적 태도를 보이는 이유로는 남성에게 부과되는 전통적인 성 역할 모델의 영향과 구조적 불평등에 대한 남녀의 관점 차이를 들 수 있다. 이와 같은 현실 인식의 남녀 간 격차를 줄이기 위해서는 헤게모니적 남성성에 대한 고찰, 정확한 정보를 바탕으로 한 쟁점 교육, 실수 친화적 공간 마련을 통한 쟁점의 공론화, 그리고 시민 교육의 관점에서 대학 차원의 대응이 필요하다는 점을 제안하였다.

This thesis analyzes the nature of proof in the perspective on the philosophy of mathematics. such as absolutism, quasi-empiricism and social constructivism. And this thesis searches for the improvement of teaching proof in the light of the result of those analyses of the nature of proof. Though the analyses of the nature of proof in the perspective on the philosophy of mathematics, it is revealed that proof is a dynamic reasoning process unifying the way of analytical thought and the way of synthetical thought, and plays remarkably important roles such as justification, discovery and conviction. Hence we should teach proof as a dynamic reasoning process unifying the way of analytic thought and the way of synthetic thought, avoiding the mistake of dealing with proof as a unilaterally synthetic method. At the same time, we should make students have the needs of proof in a natural way by providing them with the contexts of both justification and discovery simultaneously. Finally, we should introduce the aspect of proof that can be represented as conviction, understanding, explanation and communication to school mathematics.

This study is concerned with the bai su(背戍) of Koryo period which recorded in Kei Rim Yu Sa(鷄林類事). Results of this research can be summarized as follows : The record of Bai Su(背戍) in Kei Rim Yu Sa(鷄林類事) was correct. It was not a mistake in writing. Thus, this word(背戍) was used by the people of Koryo. The 背戍 of Koryo was related to Aramaic patash and Japanese byets or bats, バツ. It was found that 背戍 of Koryo was very similar to Aramaic patash, legging. It indicates that 背戍 was derived from Aramaic and it was a transliteration of patash. Thus, 背戍 was a borrowed word from Aramaic. Also it was found that 背戍 of Koryo and Japanese byets(ぺツ) or bats(バツ) showed a very close affininty with each other in phonetic value. These words had the same meanings of 襪 one another. It reveals that 背戍 of Koryo and Japanese byets of bats has the same origins. Japanese byets or bats were transliterations of 背戍 of Koryo and they were borrowed words from 背戍 of Koryo.

The objective of this study is to examine acoustic cues in spoken French for the assessment of pronunciation which is necessary to realization of the multimedia system. The corpus is composed of simple expressions which consist of the French phonological system include all phonemes. This experiment was made on 4 male and female French native speakers and on 20 Korean speakers, university students who had learned the French language more than two years. We analyzed the recorded data by using spectrograph and measured comparative features by the numerical values. First of all, we found the mean and the deviation of all phonemes, and then chose features which had high error frequency and great differences between French and Korean pronunciations. The selected data were simplified and compared among them. After we judged whether the problems of pronunciation in each Korean speaker were either the utterance mistake or the interference of mother tongue, in terms of articulatory and auditory aspects, we tried to find acoustic features as simplified as possible. From this experiment, we could extract acoustic cues for the construction of the French pronunciation training system.

In this paper, we study the subject-matter knowledge related to the problem about rational exponent with negative bases. From the school mathematics point of view, we first investigate the meaning of the extensions of the number systems. We analyze the intrinsic meaning involved in the (-8)$^{1}$ 3) through the natural interpretation of rational exponent with negative bases by the complex number. we explain why it is important for a teacher to have the subject-matter knowledge in order to detect and correct student\`s mistake and misunderstanding.
