One might have a retrospect on the relationship between the forest and human being from the viewpoint of ecological perspective. It is no doubt that most of the fossil humans should have lived on the forest and the latter provided foods and shelters for humans from their beginning stages, Since the so-called agricultural revolution, humans have extensively started to exploit the forest which had beer, their cradle. The industrial revolution has created another situation against the forest in terms of the quality of ecosystem. These two revolutions have set up the so-called civilization which seems to have been based on the sacrificial oblation of the forest. The cradle for human being has been kept exterminating for the shake of "economic development and miracle." This might be a synoptic history of relationships between the forest and human beings in a sense. designates the behavioral aspects of human being against the forest and people consider the forest only as exploitable resource in this context, and the latter means that people live on the forest and strive to adapt the order of forest ecosystem. The resourcism has developed a strategy of colonialism to exploit the forest and provided a winner's position for the human beings against the forest, This idea and behavioral perspective seems to have started the backfire against the exploiter who is the owner of the civilization. However, there are different philosophies and ideas to view the relationship between the forest and human beings. People within the forest who are mostly considered as "primitives" still keep their idea of the ontology of the forest. There is a theoretical assumption of the "socionatural system" to look into the ecosystem. The forest could be viewed in the above frame of analysis. There are five variables : environment, resource, technology, organization, and ideology. Ideological aspect of the forest can be explained in the context of belief systems. Forest has a meaning of religion and rituals and people within the forest should admire it in anyway of religious reasons. This aspect of the forest cannot be separated from the environmental aspect of the forest. People within the forest acknowledge and practice the above idea. People outside the forest have lost the idea, however, at the cost of acquiring the civilization. They have expelled themselves from the forest and divided the socionatural system of the forest by way of colonialism. The efforts like agroforestry and social forestry would be strategies for recovering the idea of ontology of the forest as well as the sense of community including the forest and human being. People within the forest will be a prospective model for the future socionatural system of the forest for the people outside the forest. At this point, an ecological anthropologist can work with the forest specialists.

하천의 수리 및 하도의 특성으로 대표되는 물리적 환경(하도 및 수리 특성)은 생태계 기반으로서 수질특성과 더불어 생물에 미치는 영향이 아주 크다. 따라서 하천의 물리적 환경을 진단하고 평가하는 경우에는 상 중 하류의 위치에 따른 하도의 지형학적 특성과 하천의 규모 및 유량의 크기 등에 따라 하천의 유형을 분류하고 그 유형별 특성에 따라 하천환경의 평가시스템을 구축할 필요가 있다. 1980년 후반 이후에는 세계 각국에서 환경보전, 하천복원 및 하천관리 등 종합적인 하천공학적 관점에서 적용할 수 있는 하천분류체계가 제시되었으며 1990년대 이후 선진국들은 정성적 또는 정량적인 하천의 서식환경 평가시스템을 구축하여 적용하고 있으며 대표적으로 정량적 평가시스템을 운영하는 국가는 독일과 미국이고, 정성적 평가시스템을 운영하는 국가는 영국이며, 호주는 영국과 미국의 평가시스템을 통합한 시스템을 운영하고 있다. 한편, 국내에서는 하천환경에서 생태계 기반인 하천의 물리적 특성(구조)에 대한 평가 및 진단 절차도 없이 시행되고 있는 사례가 대부분이다. 또한 지금까지는 하천의 자연도 평가 연구 등에서 선진국들의 하천환경평가시스템을 여과 없이 적용함으로써 국내의 하천특성을 제대로 반영하지 못하는 문제점을 노출하고 있다. 따라서 국내 하천의 물리환경 평가시스템에서는 생물 서식의 기반이 되는 하천의 하도지형 특성 및 수리특성을 반영할 수 있어야 한다. 하천평가에 앞서 하천유형 분류에 따른 하도특성은 하상경사에 따라서 급경사 하천(high-gradient stream), 중경사 하천(mid-gradient stream), 완경사 하천(low-gradient stream)으로 구분하였으며 하천의 물리환경 평가시스템의 평가영역 및 평가지표는 정량적 평가시스템을 운영하는 독일(LAWA, 2004)과 미국(EPA, 2004)의 연구결과를 참고하여 공통지표를 추출하고, 우리나라의 하천이용 및 정비현황을 반영하여 하천유형을 3가지로 분류하고 각 하천유형에 대하여 3개 영역 10개 평가지표를 5개 등급으로 구분하여 평가시스템을 구축하였다. 하천에 대한 하천 지형특성과 현황을 조사할 항목은 수리 및 하도영역의 6개 항목, 하안영역의 2개 항목, 하천교란 영역 2개 항목으로 3개 영역으로 구분해서 평가하고 그 점수에 따라 1등급은 매우좋음(1등급)상태의 $20>{\sim}18{\geq}$점, 좋음(2등급)상태의 $18>{\sim}14{\geq}$점, 보통(3등급)상태의 $14>{\sim}8{\geq}$점, 나쁨(4등급)상태의 $8>{\sim}14{\geq}$점, 매우나쁨(5등급)상태의 4>점으로 등급을 산정하였다. 매우 좋음의 1등급은 참조하천이며 좋음~매우나쁨의 2등급~5등급은 비교하천으로 구분하였으며 보통보다 높은 경우는 자연하천, 낮은 경우는 인공하천으로 나누어 서식처 기반에 따라 평가체계를 구축하였다. 한국형 하천환경 물리평가 체계가 확실히 구축되기 위해서는 각자의 평가 등급이 적절하게 평가 되는지를 검증해야 하기 때문에, 본 연구에서는 하천유형별 자연하천과 인공하천을 비교 분석하였고 평가 영역별 평가지표를 기준으로 상관분석을 통한 상관성을 분석하고 더 나아가 가중치의 적절성 및 각각의 등급에 미치는 영향을 검토하고자 한다.

This review paper discussed the decadal fluctuations in the catch of the common squid, Todarodes pacificus (T. pacificus) by focusing on migration and distribution patterns. Since 1980s, changes in T. pacificus catches were due to climate regime shift in Korean waters. Fluctuation patterns of catches were different between the East Sea and the Yellow Sea. Generally PDO (Pacific Decadal Oscillation) phase shows a negative correlation with strength of warm current to the East Sea. In 1980s when PDO was positive phase (+), T. pacificus catch was higher in the Yellow, but it was lower in the East Sea. In 1990s when PDO was negative phase (-), T. pacificus catch showed opposite trend compared with 1980s. Such spatial and decadal fluctuations of T. pacificus catch were due to its northward migration along with the warm current or southward movement against the current. In the East Sea, strong (weak) warm current period, the current path has been shifted toward the East Sea coast of Korea (central East Sea or the coast of Japan). It has a correlation with PDO. In the positive PDO phase (1980s), the fishing ground was located on the eastern side of Ulleungdo, whereas during negative PDO phase (1990s), they were situated near the southeastern coast of the Korean peninsula. In the 1980s, volume transport passing into the Yellow Sea increased, whereas volume transport in the East Sea decreased. This is one of major reason increasing T. pacificus larvae in the Yellow Sea.

This research was executed to select beneficial antagonists from digestive organ of Allomyrina dichotoma larva that can be put on environment friendly control against phytopathogenic fungi. We screened 38 bacterial strains inhibiting mycelial growth against eight plant pathogens through dual culture assay. The 10 strains among 38 bacterial strains were selected as beneficial microbes showing antifungal activity against Botrytis cinerea, Plasmodiophora brassicae, Colletotrichum acutatum and Phytophthora capsici through under greenhouse pot trials. The 10 bacterial strains that shown strongest antifungal activity were classified into 3 genera and 10 species, and identified as the genus Bacillus (DM146, DM152, DH2, and DH16), Paenibacillus (DF30, DH14, and DM142) and Streptomyces (DF137, DM48, and DH92) by morphological characteristics and 16s rRNA gene sequence. The 10 bacterial strains had solubilizing activity of insoluble phosphates, production of IAA (indole-3-acetic acid), β-1,3-glucanase and protease. Among the 10 bacterial strains, DM152 strain was produced significant enhancement of all growth parameters of chili pepper and tomato seedlings under greenhouse condition. Thus, this study demonstrated that gut microbes of Allomyrina dichotoma larva will be useful as a potential biocontrol agent against plant pathogens and biofertilizer.

It's the situation that modern technological civilization shakes the life environment fundamentally without a serious reflection on the dangers. The sense of crisis' brought the rise of modern Ecology in awareness of survivability of the humanity. Because the serious reflection is not just a campaign for environmental protection, but is to establish the values which is possible to coexist and to make harmony between the nature and man, man and man, and to form a healthy relationship through philosophical thought and practice has intrinsic value for human and nature. Under these circumstances, if Yulgok lives now and he is questioned by the ecological theorists of the 21st century that "What do you think about the serious environmental problem of present times?", what really would be his explanation? In the presentation methods of the explanation, will question first what contents western ecologists who study Theory of the environment in technology, Deep Ecology, and Social Ecology propose, then will compare and introduce what similarities and differences from theirs. As a result, we'll be found that Yulgok's thought, moral consciousness, about the nature and humanity as a confucian scholar.

This thesis investigates the cultural meanings of the first optical instrument, Camera obscura, in the pre-modern age, while it explains the development as well as the use of the Camera obscura in Europe and Korea. For this purpose the thesis traces the significant phases of the historical developments of the Camera obscura from L. da Vinci, G. B. della Porta, D. Barbaro, A. Kircher to J. Zahn etc. The Camera obscura was not only the symbolic instrument of the modernism in the sense that human being wanted to observe the outer world by himself and to be freed from the viewpoint of the christianity, but also was the forerunner of the modern visual culture, because it first time reproduced the artificial image of the natural world. Since the second half of the 17th century the box-type reflex Camera obscura had been produced, it began to be used as aid to drawing for painters like J. Vermeer, A. Canaletto and J. Reynolds etc. throughout Europe. It tells the evidence of the close relation between art and technology in the pre-modern age. Around the end of the 18th century the Camera obscura was brought to Korea, the closed country of the Fareast, by the scholars of the so-called 'Realist school' (Silhak-pa) who went to Beijing to acquire knowledges on the Western science from the European priests. In 1780s Yak-yong JUNG, one of the representative scholars of the Realist school, experimented the Camera obscura, and then, it was used for sketches of higher aristocrats' portraits by the supreme portrait painter of that time, Myoung-ki LEE. Those were possible only under the reign of the culturally liberal and reformative King, Jung-jo (ruled 1776-1800), and after his retreatment the inquiry of the Camera obscura had been dimished. It is not a historical coincidence that the Camera obscura could be examined and used in the period of the Enlightment both in Europe and Korea.

The monthly news and culture magazine, 'Sasanggye,' established by Jang Jun-ha from 1953 to 1970, served as a platform for government criticism and intellectual representation. The magazine created photographic-essays covering a variety of topics and utilized images as a visually impactful tool with news value. This paper aims to critically examine the photographic-essays within 'Sasanggye' as archival records, shedding light on their intrinsic value. Before delving into this assessment, the paper thoroughly explores the developmental process and characteristics of these photographic-essays. And based on the content divisions within the main text, the paper categorized the themes captured in the photographic essays into politics, economics, society, culture, and miscellaneous topics. It then introduced representative photographicessays. From an archival perspective, looking at photographs involves elucidating that photographs carry meanings beyond mere data. The photographic essays in 'Sasanggye' serve as photographic records providing evidence of 1960s Korean society and encapsulating crucial visual information. Furthermore, the photographic essays in 'Sasanggye' hold a historical significance in the aspect of Korean magazine documentary photography. The photo-essays in 'Sasanggye' carry worth in the history of photography and encompass evidential and informational values as photographic records.

This study aimed to determine whether middle school students could understand global warming and the greenhouse effect, and explain them in terms of global radiative equilibrium. From July 13 to July 24 in 2021, 118 students in the third grade of middle school, who completed a class module on 'atmosphere and weather', participated in an online assessment consisting of multiple-choice and written answers on radiative equilibrium, the greenhouse effect, and global warming; 97 complete responses were obtained. After analysis, it was found that over half the students (61.9%) correctly described the meaning of radiative equilibrium; however, their explanations frequently contained prior knowledge or specific examples outside of the presented data. The majority of the students (92.8%) knew that the greenhouse effect occurs within Earth's atmosphere, but many (32.0%) thought of the greenhouse effect as a state in which the radiative equilibrium is broken. Less than half the students (47.4%) answered correctly that radiative equilibrium occurs on both Earth and the Moon. Most of the students (69.1%) understood that atmospheric re-radiation is the cause of the greenhouse effect, but few (39.2%) answered correctly that the amount of surface radiation emitted is greater than the amount of solar radiation absorbed by the Earth's surface. In addition, about half the students (49.5%) had a good understanding of the relationship between the increase in greenhouse gases and the absorption of atmospheric gases, and the resulting reradiation to the surface. However, when asked about greenhouse gases increases, their thoughts on surface emissions were very diverse; 14.4% said they increased, 9.3% said there was no change, 7.2% said they decreased, and 18.6% gave no response. Radiation equilibrium, the greenhouse effect, and global warming are a large semantic network connected by the balance and interaction of the Earth system. This can thus serve as a conceptual system for students to understand, apply, and interpret climate change caused by global warming. Therefore, with the current climate change crisis facing mankind, sophisticated program development and classroom experiences should be provided to encourage students to think scientifically and establish scientific concepts based on accurate understanding, with follow-up studies conducted to observe the effects.

The study began in recent years with the aim of grasping the nation's medical status following the fast-growing trend of international medical tourism and attracting foreign patients, among other things, Busan, which ranks second in attracting foreign patients after the nation's capital, Seoul, has been highly active in the past eight years, with foreign patients rising by about 426 percent, and Russian patients entering the sea. In addition, Gimhae and Changwon, the Busan-based Gyeongsangnam-do region, ranked first and second in number of foreign residents, and are inhabited by a variety of foreign workers. Medical institutions, such as hospitals, should be able to find directions within hospitals. It is also a space where information in various languages, including Korean, English, Chinese, or Russian, must be delivered in a single medium. Based on this research, the purpose of this research is to provide converged information that helps foreigners who are not familiar with Korean language easily understand the proposed recognition system when visiting hospitals. Therefore, this paper is applied to a multi-language survey of six medical institutions (A, B, C, D, E, F) at the university hospital in Busan, and 10 medical institutions (R, J) in Gimhae, South Gyeongsang Province with high foreign residents. Research results and contents are as follows. First, the results of analyzing the design of the sinusoidal system show that the font uses colorless Gothic fonts, arrows, and pictograms to introduce the design of a typical hospital sign system. Second, the results of the multi-lingual situation were found to have only two languages in the system, such as Korean and English, and to have four languages, including Korean, English, Chinese, and Russian, according to their geographical location. However, it was judged that most medical institutions currently have only two languages (Korean, English) that may cause some discomfort in terms of language for foreign patients in non-English speaking countries. Based on these findings, it is necessary to propose designs that are considered by Koreans as well as foreign users in the use of multilingual hospital sign systems.
