  • The film House of Hummingbird intersects Korean modern history and personal history through the eyes of a teenage girl, and closely explores how patriarchy and Korean capitalism leave traces and internal impressions on the growing up of the female subject. This film is a meaningful text in terms of showing what changes can occur when the subject is transformed from a boy to a girl in the narrative of growth and when a feminist point of view is entered. House of Hummingbird reveals the weakness of the patriarchal symbolic order through the gaze of a teenage girl in the episodic narrative composition, and also discovers the possibility of close relationships and bonds between women in the gaps. In particular, Yeong-ji, the main character girl Eun-hee's Chinese language school lecturer, is a new female character that has never been seen in Korean teenage films. As a result, in House of Hummingbird, we meet a new female subject who negotiates the pain of growth in a 'good enough' condition.

  • Rare earth elements, which are important components of motors, are in high demand and thus constantly get more expensive. This tendency is driven by the growth of the electric vehicle market, as well as environmental issues associated with rare-earth metal manufacturing. TC 298 of the ISO manages standardization in the areas of rare-earth recycling, measurement, and sustainability. Korea, a resource-poor country, is working on international standardization projects that focus on recycling and encouraging the domestic adoption of international standards. ITU-T has previously issued recommendations regarding the recycling of rare-earth metals from e-waste. ISO TC 298 expands on the previous recommendations and standards for promoting the recycling industry. Recycling-related rare earth standards and drafts covered by ISO TC 298, as well as Korea's strategies, are reviewed and discussed in this article.

  • Wireless earphones are products that are consumed together with smart devices (mobile phones, etc), and there is no twisting and convenience compared to general earphones. However, due to the lack of information on the quality of wireless earphones, consumers tend to purchase products based on brand awareness, and manufacturers deliver information to consumers based on different standards for each product due to the lack of standards for measurement methods for quality evaluation. In particular, the playback time of wireless earphones is a factor that can directly affect consumers' purchases, so it is necessary to prepare a standardized test method to properly measure it. This paper introduces the current status of wireless earphones and related standard trends, and proposes a method for measuring the audio playback time of wireless earphones developed through this. In addition, this measurement method will be proposed as an international standard (IEC) after being established as the national standard, the Korean Industrial Standard (KS).

  • This article focuses on the period from the beginning of Twentieth, the period commonly regarded as the Enlightenment Period in Korea. Questioning Daehan-Sin-Gygi( 問答大韓新地誌) textbook consists of contents of physical geography aimed at rational and objective perception of the nature, within the frame of Sirak(實學) and Progressive Thoughts. In terms of contents organization, there are too wide range of facts and knowledge covered, with mechanical imitation of statement style of systematic and regional approach. Particularly, Geography textbook in this period attached greater importance to contents of physical geography than any other times. It is possible to conclude that real outcomes of geography education at the time contributed significantly to enlightenment of people and integration of the society. I consider that statement style of question-response used at the time is very worth-while.

  • The kinetic study of rifamycin B production in batch culture of Nocardia mediterranei was undertaken in part of our endeavor to optimize the fermentation condition. The growth parameters such as $\mu$$_{m}$ and Ks values for nitrogen source were evaluated by employing Monod equation. From the experiments, $\mu$$_{m}$ and Ks were 0.15hr$^{-1}$ and 8.35g/1, respectively. The growth kinetics in batch culture was found successfully interpreted by logistic law, i.e., the initial specific growth rate and the maximum cell mass concentration were determined as function of pH and both found to have maxima. For the production of rifamycin B, a non-growth associated production kinetics was employed and the specific productivity as a function of pH was found to have two maximum points. The yield coefficient and the specific productivity were calculated as mean values in production phase. Utilizing these experimental data as a function of pH, the optimal condition for the rifamycin B production was discussed with regad to the pH effect on the cell growth and production of the antibiotic. As a result, growth phase at pH 6.5 and production phase at pH 7.0 were found to be recommended.ded.

  • Teacher interventions in science classrooms are important because they can have a major impact on students' practices. This study qualitatively analyzed what kinds of utterances teachers used to intervene in students' practices of constructing scientific explanations. Two elementary school teachers, L and K, participated in the study, and their lessons in the sixth-grade science unit, 'Structure and Function of Plants' were reorganized for students to engage in the scientific practice of constructing explanations. In each lesson, the two teachers were asked to support students' practices as part of responsive teaching. The results of the study showed that the two teachers mainly utilized empathetic and disciplinary utterances, respectively, which were used to support emotional, processual, and conceptual aspects of students' scientific practices. The empathetic utterances were employed to support students' practices in the order of noticing, actively accepting, and offering alternatives. By contrast, the disciplinary utterances were used in the order of finding deficiencies, evaluating, and urging to improve students' practices. The reasons the teachers made use of empathetic and disciplinary utterances, respectively, were discussed, and implications for science education were suggested.

  • Sonoluminescence (SL) is the light emitting phenomenon accompanied with ultrasonic cavitation in liquid. It attracts many interests because physics behind it remains uncertain and few applications have appeared. It has been known that the color of SL changes in solutions which include metallic ions. In the present work, colors of SL in alkali metallic and alkaline earth metallic ions were considered. RGB component was used to analyze the color of SL. By using RGB component, it was found that color of SL in metallic solution can be resolved into color of SL in pure water and flame color of metal which is different from high intensity color of line spectrum of alkaline earth metal. From this result, influence of metallic ion on SL and the temperature on violent collapsing of cavitation bubble was discussed.

  • Since the endosaccular coil embolization technique was introduced as an alternative for treating selected patients with aneurysms, it has become a mainstay of treatment for cerebral aneurysms. In lesions with a neck larger than the aneurysmal body, an irregular shape, or arterial branches incorporated within the sac, endovascular treatment using detachable coils are traditionally contraindicated because of technical difficulties. Coil embolization has evolved as a result of both the development of related devices and the introduction of technical improvements using various devices. Use of various technical and device options can make endovascular treatment of cerebral aneurysms safer and can widen the treatment indications. Various technical options, including the technical modification of device-assisted techniques, will be presented, and the related practical points will be discussed in this issue.

Recognition and Narrative Aspects of the History of Korean Classic Literature from Two Korean Literature History Works Written in China (중국 한국문학사 2종의 한국고전문학사 인식과 서술 양상: 남북한문학사와 자국문학사의 수용과 변용을 중심으로)

  • This study focuses on two specific history of Korean literature in Chinese: the outline of The History of Joseon Literature (2010) by Li Yan and The History of Joseon Literature (1988, 2008) by Wei Xu-sheng; it was conducted to compare narrative viewpoints to the history of South and North Korean literature and therefore identify distinguishable characteristics. As a result, the following was concluded. First, The History of Korean Literature by Cho Dong-il and The History of Korean Literature in North Korea (15 volumes) include thorough discussions on division of historical eras, concept of genres as well as individual literary works and applied such discussions on writing literary history. However, Wei Xu-sheng and Li Yan's The History of Korean Literature did not illuminate theoretical discussion of South and North Korea. Li Yan's outline of The History of Joseon Literature was published in 2010 and the first edition of Wei Xu-sheng's The History of Joseon Literature was published in 1986 and later was published as revised editions in 2000 and 2008. Regarding published dates, it is a matter of course to reference Cho Dong-il's The History of Korean Literature, published in the 1980s, or The History of Korean Literature in North Korea (15 volumes), published in the 1990s; nevertheless, neither Wei Xu-sheng nor Li Yan used those texts in their works. Their works were heavily influenced by the narrative tradition of the history of national literature and therefore, entailed unsophisticated discussion on the division of historical eras or the concept of genres. Second, those two texts also emphasized external factors such as politics, society, economy and culture and explicitly mention these factors in historical overview of each chapter. Such an approach is commonly used in narratives of literary history under socialist regimes, including The History of Korean Literature in North Korea (15 volumes). Accordingly, evaluations based on 'political standards' - stress of people, nationality, practicality and so forth - in main texts are particularly accentuated, akin to narratives of literary history under socialist regimes. Finally, since those two Korean literature history works are written by Chinese scholars, they focus on correlation between Chinese literature history and Korean literature history. However, several genre-related terminologies such as Xiaopin (a kind of essay), Yuefu (a kind of popular song/poem), Yuyan (fable), Shuochang (telling of popular stories with the interspersal songs), Shizhuan (biography or/and memoirs in history) were adopted directly from Chinese literature. In analyzing Korean literature using terminologies introduced from Chinese literature, differences between original and alternative definitions were not examined in detail. While some terminologies and concepts were adopted directly without further consideration as to state of the two nations, it is also interesting to note that dichotomy, mainly used in Korean literature history, was used to discuss the genre of Cheonki (romance tale), relevant to Suyichon and Keumosinhua, rather than follow traditions of Chinese literature history.
