A physically based semi-distributed model, SWAT was applied to the Chungju Dam upstream watershed in order to investigate the spatial and temporal characteristics of watershed sediment yields. For this, general features of the SWAT and sediment simulation algorithm within the model were described briefly, and watershed sediment modeling system was constructed after calibration and validation of parameters related to the runoff and sediment. With this modeling system, temporal and spatial variation of soil loss and sediment yields according to watershed scales, land uses, and reaches was analyzed. Sediment yield rates with drainage areas resulted in $0.5{\sim}0.6ton/ha/yr$ excluding some upstream sub-watersheds and showed around 0.51 ton/ha/yr above the areas of $1,000km^2$. Annual average soil loss according to land use represented the higher values in upland areas, but relatively lower in paddy and forest areas which were similar to the previous results from other researchers. Among the upstream reaches, Pyeongchanggang and Jucheongang showed higher sediment yields which was thought to be caused by larger area and higher fraction of upland than other upstream sub-areas. Monthly sediment yields at the main outlet showed same trend with seasonal rainfall distribution, that is, approximately 62% of annual yield was generated during July to August and the amount was about 208 ton/yr. From the results, we could obtain the uniform value of sediment yield rate and could roughly evaluate the effect of soil loss with land uses, and also could analyze the temporal and spatial characteristics of sediment yields from each reach and monthly variation for the Chungju Dam upstream watershed.

This study is a case study examining how research-based 'authentic' science education program contextually facilitates students' learning on NOS as a process. We developed 'Becoming a Scientist' mentor-mentee program and applied it to six Korean 7th graders for 8 months. A mentor, who is also a researcher, provided scaffolding and coaching, and her mentees were to perform the whole process of science research, including selecting the research subject and questions, planning research design, doing experiments, collecting and analysing data, writing research paper, and experiencing poster presentation at an academic conference. The research questions are 1) What would the students experience at every step of their research process?, and 2) Which perceptions would they construct NOS as a process? Data include classroom observations, interview, mentor's journal, and students' learning products. The results show that the mentees have experienced their views of NOS as a process in various ways such as role of research question and purpose, validity of measured value, researcher's subjectivity in interpreting data, experience of making public and peer review, and significance of academic conference. This study has shown that students' actual experience in scientific research enhanced their views about NOS as process without explicit and reflective approaches. We defined 'authenticity' associated with not only with its similarity to what scientists do but to learner's identity as scientific researcher. Based on the situated learning theory, this study sheds light on the necessity of reconsideration about the meaning of authenticity and embodying authentic context in science education for better NOS learning.

This study examines whether and how ages of child affect accessibility experiences of women and men differently. Space-time accessibility measures based on Time-geographic framework with activity-travel diary datasets in Portland Metro, US were calculated using GIS-based geocomputation, and spatial-temporal patterns of accessibility of dual-earner couples by ages of their youngest child were compared. The results are as follows. (1) Although more women than men work part-time, which would render women more spatial-temporal autonomy, accessibility levels of women are not higher than men's. It implies that there exists another constraint placed on women which largely stems from gender inequality. (2) It is distinctively women with child under age 6 of which accessibility spaces are found to be restricted doser to home compared to men. Women with no child or with child aged over 6, however, show more or less similar spatial-temporal patterns of accessibility with men's which are quite unvarying regardless of parental status and their child age. Women's accessibility experiences characterized by spatial-temporal entrapment, thus, can be seen as problems associated with gender rather than sex. (3) Intensified spatial-temporal entrapment of women with young child are associated with the significant spatial pegs shaping their accessibility spaces, which are located much closer to home compared to men's: workplaces and child's daycare centers.

The present study aims to analyze the extent of the use of STS contents in the areas of 'Evolution of Life' and 'Health of Humanity and Scientific Technology' in 'Science' textbooks and to determine whether they meet the goals of the curriculum revised in 2009. The analysis of the 7 types of textbooks according to the STS topics areas indicated big differences between textbooks as little as 16.67% and as much as 58.33%. Also, among the topics associated with STS, 'Space Development and National Defense' and 'Environmental Problems' were not included. In the STS activity areas, the areas of 'Structured Debate,' 'Interpretation of Data,' 'Research and Investigation' showed great frequency. On the other hand, the STS activity areas of 'Field Activities,' 'Problem-solving and Decision-making,' 'Role Playing,' 'Simulation,' 'Case Study,' and 'Research Design' showed small frequency. Analysis of the STS contents for each area indicated 67.57% for the contents relevant to 'the applicability of science' accounting for the largest part whereas 'Understanding of Occupations related to Science' accounted for 1.63%, showing a great difference in their frequency. Seven standards except 'the applicability of science' were included each contents beyond 10% or less than 10% proportion. The STS contents included in the life science area of the 7 types of convergence-style 'Science' textbooks for the high-school accounted for an average of 20.75%, from as little as 12.35% to as much as 26.90%, depending on the publishes.

The purpose of this study is to define the teachers' perception for technology leadership when utilizing the Digital Textbook (DT). The subjects of this study were 97 elementary school teachers (40 males and 57 females) working in digital textbook research schools that implemented digital textbooks in 2009. Needs assessment instrument was revised based on previous instruments. Perception was calculated using Borich formula. According to the results, teachers of digital textbook research schools recognized 'teachers' instructional methods' as the most important area, while the least recognized area was 'support by the school'. The highest technology leadership needs by categories included 'role setting between members when implementing digital textbooks', 'instructional methods to cultivate creativity when using digital textbooks', 'troubleshooting digital textbook problems', 'additional staff support in case of problems', 'development of various assessment tools for measuring the effect of the digital textbook', and 'support of digital textbook resources for students with disabilities'. Based on these results, the study proposed specific methods to enhance technology leadership for the successful introduction of digital textbooks in schools.

Directly converting the focal depth and image size of computer-generated-hologram (CGH), which is obtained by calculating the interference pattern of light from the 3D image, is known to be quite difficult because of the less similarity between the CGH and the original image. This paper proposes a method for separately converting the each of focal length of the given CGH, which is composed of multi-depth images. Firstly, the proposed technique converts the 3D image reproduced from the CGH into a Light-Field (LF) image composed of a set of 2D images observed from various angles, and the positions of the moving objects for each observed views are checked using an object detection algorithm YOLOv5 (You-Only-Look-Once-version-5). After that, by adjusting the positions of objects, the depth-transformed LF image and CGH are generated. Numerical simulations and experimental results show that the proposed technique can change the focal length within a range of about 3 cm without significant loss of the image quality when applied to the image which have original depth of 10 cm, with a spatial light modulator which has a pixel size of 3.6 ㎛ and a resolution of 3840⨯2160.

This overview study of mass culture is based on an academic point of view and based thereon an investigation of mass culture from a psychological standpoint follows. This study reviewed previous studies of mass culture that have been done so far divided into Producer-oriented, Text Decoding-oriented, and Recipient Theory, according to subjects of the study. The studies were also reviewed from the viewpoints of industry, consumer science, education, and developmental psychology. Further, it was discussed how trends and limitations in research were covered according to each viewpoint on mass culture. Based on the analysis, this study aims to promote overall psychological interest in studies of mass culture; to present the necessity of analysis and measurement of emotional experience on mass culture; to increase the roles of industrial and consumer science approaches in terms of planning and culture; to change the viewpoint of developmental psychology that accepts youth culture positively; and, to present interdisciplinary studies related to mass culture. Mass culture has already penetrated deeply into real life but there are few analyses and interpretations of mass culture in terms of psychology. This study is meaningful from the aspect that discussion of mass culture has been placed in a position that recognizes the entity of and interest in mass culture. Through this study, I hope that the scope of interest in psychology will expand and that approaches to mass culture will become more diversified.

Recently, I presented Gagok(歌曲) Collection Yeong-eon永言 to learned circles. Yeong-eon is very similar to Yukdang-version六堂本 CheongGuYeongeon靑丘永言. Compared with Cheong- Yuk, it is the same age or little bit early time of Cheong-Yuk in culture Icon. This paper paid attention to the considerable difference between Yeong-eon and Cheong-Yuk in the way of the distribution of Yisakdaeyap二數大 葉's Woo mode羽調 and Ke-myeon mode界面調. There was the way of gathering ‘real name’+‘namelessness’ in Yisakdaeyap, which is the feature of the 18th century Gagok Collection. I found this way just put on the 19th century Gagok Collection way which is the distribution of Yisakdaeyap's 'Woo mode and Ke-myeon mode' in CheongYuk. Then I proved in this paper that the way of gathering Yisakdaeyap in Cheong Yuk didn't correspond to an actual singing in the early 19th century when 'Woo mode and Ke-myeon mode' was fixed. In case of Yeong-eon, however, it was not written any writers' names at all, when it was researched retroactively, I knew it was distributed evenly both the works of 'real name' and 'namelessness' in Yisakdaeyaps 'Woo mode and Ke-myeon mode'. Consequently, I found Yeong-eon is the good Gagok Collection for an actual singing at that time. In addition, there was discord in the mode or key distribution among many Gagok Collections. I found this issue of the application had kept on make Gagok Collections edit during 2 centuries. Because the actual Gagok enjoyment in the specific time is connected the way of the mode application directly.

Makoto Shinkai, an animated film maker in Japan, has been featured as a one-person production system and as a 'writer of light', but his 2016 release of "Your Name" was a departure from the elements that characterize his existing works. At the same time, by the combination of the traditional musubi(むすび) story, ending these, it was a big hit due to its rich narratives and attraction of open interpretation possibility. As it can be guessed from the title of this work, this work shows the encounter between the Japanese ancient language and the modern language in relation to the 'name', and presents the image that the role of the name(language) is repeatedly emphasized with various variations in events for the perfect 'encounter'. In this work, the interpretations of $Signifi\acute{e}$ for characters and objects are extended and reserved as a metaphorical role of the similarity, depending on the meaning of the subject which they touch. The relationship between words and objects analyzed through the structure of Signifiant and $Signifi\acute{e}$ is an epoch-making ideological discovery of modern times revealed through F. Saussure. Focusing on "the difference" between being this and that from the notion of Saussure, Derrida dismissed logocentrism, rationalism that fully obeyed the order of Logos. Likewise, dismissing the center, or dismissing the owner had emerged after the exclusive and closed principle of metaphysics in the west was dismissed. Derrida's definition of 'deconstruction' is a philosophical strategy that starts with the insight on the nature of language. 'Dissemination,' a metaphor that he used as a methodological concept to read texts acts as interpretation and practice (or play), but does not pursue an ultimate interpretation. His 'undecidability' does not start with infinity, but ends with infinity. The researcher testifies himself and identifies that we can't be an interpreter of the world because we, as a human are not the subject of language but a user. Derrida also interpreted the world of things composed of Signifiant and $Signifi\acute{e}$ as open texts. In this respect, this study aimed to read Makoto's works telling about the meeting of a thing and a thing with name as a guide, based on Derrida's frame of 'deconstruction' and 'dissemination.' This study intends to re-consider which relationship the Signifiant and $Signifi\acute{e}$ have with human beings who live in modern times, examine the relationship between words and objects presented in this work through Jacques Derrida's destruction and dissemination concepts, and recognize that we are merely a part of Signifiant and $Signifi\acute{e}$. Just as Taki and Mitsuha confirm the existence by asking each other, we are in the world of things, expecting musubi that a world of names calls me.

비록 부정경쟁방지법의 제정 목적이 부정경쟁행위 등의 방지를 통하여 건전한 거래질서를 유지한다는 의미의 경쟁체제 확립에 있기는 하지만, 우리나라의 경우는 법 제정 당시와는 달리 사실상 산업스파이에 대한 영업비밀의 보호나 주지의 상표 영업표지의 보호와 같은 지적재산권의 보호 법률로서의 역할로 점차 변화하고 있고, 특히 부정경쟁방지법이 주지의 상표에 대한 출처의 혼동에 대한 규제뿐만이 아니라 별도로 저명상표의 희석화(稀釋化) 방지라는 법익, 이에 더 나아가 도메인 네임(Domain Name)의 선점과 원산지 및 품질의 오인(誤認) 야기행위, 주지 저명한 타인의 디자인(Design), 캐릭터(Character)와 같은 상품의 표지에 이르기까지 지적재산권과 관련된 보다 넓은 법익의 보호까지 수행하게 되면서 그 기능은 날로 강화되고 있는 상태이다. 이에 반하여 부정경쟁방지법상의 부정경쟁행위 자체에 대한 규제는 사실상 주지 저명한 타인의 상표나 상품표지의 식별력이나 출처표시기능 등의 보호라는 의미의 분쟁수준을 넘지 못하고 있어, '경쟁법'으로서의 역할은 상대적으로 미약해지고 있는 것 또한 현실이다. 또한, 공정거래법 제23조 제1항 제8호를 비롯하여 현행 공정거래법상의 불공정거래행위에 대한 규정체제를 살펴보면, 해석 여하에 따라서는 부정경쟁방지법상의 부정경쟁행위가 대부분 공정거래법상의 불공정거래행위의 범위 내로 포섭될 수도 있는 상황이기도 하다. 이에 양 법률의 성격과 역할, 앞으로 나아가야 할 방향을 고민하지 않을 수 없고, 이와 같은 논의는 발전적 입법론으로서의 가치를 갖는다. 물론 불공정거래행위(부정경쟁행위)에 대한 규제에 있어서 반드시 독일법체계에 따를 것인지 아니면 미국의 경우를 따를 것인지에 대한 선택 자체가 논리적으로 양립 불가능한 것은 아닐 것이지만 우리나라의 경우는 1980년 "독점규제 및 공정거래에 관한 법률"이 제정되는 과정에서 당시 부정경쟁방지법에 담겨 있던 기존의 부정경쟁행위에 대한 규정과 공정거래법상의 불공정거래행위와의 경합이나 중복문제는 마땅히 검토되었어야 했음에도 불구하고 공정 거래법의 제정과정에서 사실상 부정경쟁방지법의 존재 자체가 간과되어 오늘에 이르고 있다. 그동안 양 법률상의 규정 중복이나 충돌을 정식으로 문제 삼았던 바는 없었지만 '발전적 입법론' 이라는 차원에서 살펴 보면 부정경쟁방지법상의 부정경쟁행위에 대한 규제는 앞으로 공정거래법체계 내의 불공정거래행위로 포섭할 필요가 있고 이를 통하여 경쟁정책의 전문 전담기구로서 불공정거래행위에 대한 규제의 중심에 서 있는 공정거래위원회를 중심으로 효율적이고 통일적인 경쟁정책을 확립을 기대하여 볼 수 있을 것이다. 이 과정에서 공정거래법의 변화 또한 뒤따라야 하는데, 부정경쟁방지법상의 부정경쟁행위의 편입에 따라 불공정거래행위에 대한 규정 일부를 알맞게 다시 수정하는 것에 그치지 않고, 기존 부정경쟁방지법이 인정하고 있었던 사인간(私人間) 금지 또는 예방청구권 또한 공정거래법으로 그대로 편입되는 방향으로의 입법 개선이 이루어질 필요가 있으며, 그동안 '부정경쟁방지법의 공정거래법으로의 편입문제'와는 전혀 무관하게 공정거래법의 사적 구제 및 사소(私訴)의 활성화 차원의 논의로서 공정거래법상 사인간 금지청구권의 도입 여부가 검토되어 왔지만, 앞으로 이 문제는 부정경쟁방지법상 부정경쟁행위의 공정거래법체계 내로의 편입문제와 함께 이를 포함한 더욱 큰 논의로서 다시 적극적으로 검토될 필요가 있다고 본다. 이를 통하여 앞으로 부정경쟁방지법은 특허청을 중심으로 산업스파이에 대한 규제나 영업비밀의 보호와 기타 지적재산권의 보호에 온 힘을 다하고, 공정거래법은 공정거래위원회를 중심으로 불공정거래행위 (부정경쟁행위에 대한 보다 포괄적이고 통일적인 규제를 담당하여 '선택과 집중' 이라는 차원의 각 법률체계의 한 차원 높은 발전 또한 기대해 볼 수 있을 것으로 확신한다. 이러한 합의점을 시작으로 미시적인 다음 단계의 논의에 해당하는 사인간 금지청구권의 허용범위나 허용요건, 남용을 방지하기 위한 제도적 장치, 단체소송 등의 허용 여부 등의 논의도 함께 하여야 할 것이고, 이 과정에서 미국의 클레이튼법(Clayton Act)이나 가까운 일본의 입법례를 참고하여 우리의 실정에 맞는 규제의 틀을 마련함이 타당할 것이고, 이를 통하여 궁극적으로 그동안 공정거래법의 사적 집행의 활성화를 통한 경쟁질서의 확립의 강화라는 이상에 더욱 가까워질 수 있는 좋은 입법적 변화의 모습을 볼 수 있을 것이라 생각한다.
