The Dresden Elbe Valley of Germany was delisted from the World Heritage List after a long dispute amongst the city of Dresden, UNESCO and the World Heritage Committee upon a plan to build a four-lane bridge within the boundaries of the property. The plan was claimed to threaten the Outstanding Universal Value of the heritage embedded in the view of the river landscape. However looking back on the necessity of the bridge in order to maintain the city dynamics and the needs of the local population, it is possible to diagnose that plans for the bridge had a rather different nature from the usual urban 'development' plans appearing in the vicinity of other World Heritage properties. This article examines the process that led to the delisting of the Elbe Valley from the World Heritage List and assesses the problems arising between the entities which determine the value of the heritage and the entities that implement conservation measures. Recognizing the necessity of involving the local residents, this article stresses the importance of the role of communities in heritage conservation. It is also important to set up dependable directions for establishing conservation policies which takes into account the changing dynamics of the living environment, and sound methods for assessing the impact of future projects on the heritage.

Objective: The purpose of this study is to investigate how the child care teachers experience about professional vision development through participating in video clubs with their peers while watching videos about their interactions with children in the classroom. Methods: We selected three child care teachers in a day care center in Seoul area and conducted the qualitative case study. Video clubs were designed to support the quality of teacher-child interaction by developing child-care teachers' professional vision. And the video clubs used the self-reflection process and cooperative self-reflection process as an important educational method. Results: Teachers were able to experience the change of attention in watching their interaction scene through the 4-time video club participation and to have opportunity for educational (knowledge based) reasoning. Particularly, through participation in the video club, the teacher could pay attention to teachers' intention, teachers' decision making process, and child's intention. In addition, through video club participation, the teachers experienced educational interpretation based on children's thinking and interest; and reasoning through reflective thinking about the results of teaching behavior. This change of professional vision was possible through mutual scaffolding through cooperative reflection among participating teachers. Conclusion/Implications: Based on the results of this study we discussed the importance of the professional vision development of the child care teachers and the effectiveness of the video club for supporting their professional vision development.

The purpose of this study is to analyze the relationship between mentor teachers' mentoring characteristics and mentee teachers' reflective practices and to investigate mentor teachers' mentoring methods to enhance mentee teachers' reflective practices based on the analysis. The participants were four beginning science teachers and four mentors who have more than seven years of teaching experience. This study compiled mentor and mentee teachers' journals, records and transcripts from mentee teachers' five periods of classes, lesson plans, evaluation forms of lessons, one-on-one mentoring records and transcripts, questionnaires conducted before, during, and after the mentoring program, and a questionnaire about the effects of one-on-one mentoring. The mentoring characteristics of mentor teachers were analyzed based on mentor's interaction methods and the contents and frequency of the support based on teaching feedback. Mentee teachers' reflective thinking was analyzed by being categorized as voluntary self-reflections of their classes and reflections on the support provided by mentor teachers. Mentee teachers' reflective practices were analyzed by utilizing RTOP. The conclusions of this study are as follows: Mentor teachers could promote mentee teachers' reflective practices by eliciting conversation that helped mentees perceive problems in their teaching practices. Mentors' questions evoking mentees' reflective thinking could elicit mentees' spontaneous self-reflection, and it led to the enhancement of self-reflection on mentors' support and reflective practices. When mentors offered the support based on teaching practices while playing a role as a facilitator to help mentees identify and solve problems by themselves, mentees' reflective practices could be promoted.

As the importance of venture firms has increased as a new growth engine, the South Korea government makes various efforts to establish healthy ecosystems for ventures and start-ups. Especially in order to foster the competitiveness of venture firms, various support policies such as financial and R&D expenses are being expanded and promoted. In this study, the author analyzed the impact of government funding on venture firms' internal competencies and management performance by using the resource-based theory. Moreover, this study tested the moderation effect of firm's growth stages. Unlike previous studies, this study focused on qualitative rather than quantitative aspects of internal competencies and the financial and non-financial performance are used to measure the management performance of the ventures to examine the effects of government funding for venture firms in more details. For the purpose of verifying the hypothesis of this research, "The Research On The Precision Status Of Venture Firms" in 2017 from the Ministry of Small and Medium Business was utilized, which has been compiled since 1999. According to the results of this study, the government funding experience did not significantly affect the company's internal competencies and financial performance, but had a significant impact on the non-financial performance, which in turn seemed to have a significant effect on the financial performance. In addition, it was found that the technology, price, design, and quality competencies affected non-financial performance, while the organizational management and marketing competencies did not. However, the price, design, organizational management, and marketing competencies affected financial performance, while the technology competency was not. Finally, there were no differences in the effectiveness of government funding, depending on the growth stages.

Objective: A trial was conducted to investigate the effects of supplemental levels of Mn provided by organic and inorganic trace mineral supplements on growth, tissue mineralization, mineral balance, and antioxidant status of growing broiler chicks. Methods: A total of 500 male chicks (8-d-old) were used in 10-day feeding trial, with 10 treatments and 10 replicates of 5 chicks per treatment. A 2×5 factorial design was used where supplemental Mn levels (0, 25, 50, 75, and 100 mg Mn/kg diet) were provided as MnSO₄·H₂O or MnPro. When Mn was supplied as MnPro, supplements of zinc, copper, iron, and selenium were supplied as organic minerals, whereas in MnSO₄·H₂O supplemented diets, inorganic salts were used as sources of other trace minerals. Performance data were fitted to a linearbroken line regression model to estimate the optimal supplemental Mn levels. Results: Manganese supplementation improved body weight, average daily gain (ADG) and feed conversion ratio (FCR) compared with chicks fed diets not supplemented with Mn. Manganese in liver, breast muscle, and tibia were greatest at 50, 75, and 100 mg supplemental Mn/kg diet, respectively. Higher activities of glutathione peroxidase and superoxide dismutase (total-SOD) were found in both liver and breast muscle of chicks fed diets supplemented with inorganic minerals. In chicks fed MnSO₄·H₂O, ADG, FCR, Mn balance, and concentration in liver were optimized at 59.8, 74.3, 20.6, and 43.1 mg supplemental Mn/kg diet, respectively. In MnPro fed chicks, ADG, FCR, Mn balance, and concentration in liver and breast were optimized at 20.6, 38.0, 16.6, 33.5, and 62.3 mg supplemental Mn/kg, respectively. Conclusion: Lower levels of organic Mn were required by growing chicks for performance optimization compared to inorganic Mn. Based on the FCR, the ideal supplemental levels of organic and inorganic Mn in chick feeds were 38.0 and 74.3 mg Mn/kg diet, respectively.

The purpose of this study was to investigate the effect of Character-centered instruction model on pre-service science teachers' awareness of both character education and character education in science education. First of all, pre-questionnaires about the sixteen pre-service science teachers' awareness of character education and character education in science education were asked. Through the lectures during a semester, they received an education about CoProC(Collaborative Problem-Solving for Character competence) model using Character-centered instruction model and character education. After the implementation, their changes of awareness were inspected through post-questionnaires. As a result of the study, it was revealed that general pre-service science teachers' pre-awareness of character education was mostly negative. The pre-service science teachers were more aware of character education in science classes than general character education. Even that, there seemed to be a greater tendency to think in connection with specific content and subject matter and character education rather than developing competencies due to the nature of the science subject itself. However, the experiences of the CoProC model changed their perception about character into a competent point of view, and thus influenced the change in their perception of character education. Therefore, education on character education methods for pre-service science teachers at teacher training institutions will increase their expertise in character education and help establish effective character education in school in the long term.

This study selected 127 powerful Korean film producers, directors, and actors whose stable audience drawing power has been proven over the past seven years from 2013 to 2019, and viewed their network through social network analysis(SNA) to explain their power structure. It also explained the changes compared to the results of previous studies conducted on box office hits from 1998 to 2012. The producers who showed the highest audience drawing power over the past seven years were KANG Hae-jung, JANG Won-seok, LEE Eugene, HAN Jae-duk. BONG Joon-ho, KIM Yong-hwa, and RYOO Seung-wan as directors and SONG Kang-ho, HA Jung-woo, and HWANG Jung-min as actors were confirmed to exhibit the most stable audience drawing power. Meanwhile, the network formed by the 127 leading producers, filmmakers, and actors was analyzed based on closeness/ degree/eigenvector/betwenness centrality, and the result discovered a strong network involving JANG Won-seok, HAN Jae-duk, CHO Jin-woong, Don LEE, and HWANG Jung-min. This study is meaningful in that it included producers, the position which has never been discussed in previous local studies to analyze the network influencing star casting, and selected accurate box office hits by checking whether the concerned films actually reached break-even point rather than simply relying on the number of audiences or total revenue they garnered. Nonetheless, it left a hole to be filled in that it did not include the role of the management companies in the network. Therefore, a relevant follow-up discussion would be needed.

Even ordinary-looking plays can have a profound meaning. Based on this assumption, Eugene Pink (1960) has established an analytical model of play with five elements, namely "delight", "meaning", "community", "rules" and "tools." It was an effort to reflect on the true meaning of play beyond the cortical entertaining nature of play. In this study, it was carried out that all the texts containing images and performance from the EBS character "Pengsu" were selected, since he emerged as a new star in 2019. And also his play structure was analyzed by applying the Pink's model. As a result, Pengsu's play structure was confirmed to be systematic and complete as a play prototype because it was well-organized with five elements of play. It was regarded as a successful character that skillfully attracts participants to the play world. Among the components of the play, "fun" was found to be his funny appearance, sudden and unconventional behavior, "meaning" was the elimination of authoritarianism, self-esteeming and energizing, "community" was a multi-platform media user who crossed off-on-line, analog-digital-line, "rules" was to set his concept fixed as a young stranger with an ego to unreveal his identity, and "tools" was shown as his character itself and continual discourse. It shows that until now, Pengsu has a social net function of quite spreading the positive meaning of encouragement and comfort, advice and guide, consideration and forgiveness, introspection and nirvana to all members of our society, including the youth who are struggling with uncertainty and anxiety by showing rather exaggerated and stimulating performance that precisely combines these play elements.

Objectives : The aim of this study was to investigate whether the extract of Coptidis Rhizoma inhibits inflammation in chronic cold stress (CCS)-exposed mice or not. Methods : Coptidis Rhizoma extract (CRE) was made by reflux with distilled water. Male ICR mice (7 weeks old) were divided randomly into 5 groups: (1) control, (2) CCS, (3) CCS+CRE 100 mg/kg, (4) CCS+CRE 300 mg/kg, (5) CCS+CRE 1,000 mg/kg groups. Mice were orally administered once a day for 14 days starting from 1 day before CCS. Group (2)-(5) were exposed to CCS conditions that maintained at $4^{\circ}C$ for 2 h once a day for 14 days. The levels of serum cortisol and hypothalamic prostaglandin E1 (PGE1) and PGE2 were measured by enzyme-linked immunosorbent assay kit. The expression levels of several pro-inflammatory factors like heat shock protein 70 (HSP70), c-fos, and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) were measured by western blot analysis in mouse hypothalamus. Results : Oral administration of CRE 1,000 mg/kg significantly suppressed the increase of serum cortisol levels in mice exposed to CCS. CCS-exposed mice had significantly increased the expression of HSP70, c-fos, and NF-kB in hypothalamus, while CRE treatment significantly attenuated the elevation of these pro-inflammatory factors. The ratio of PGE2/PGE1 was also higher in CCS-exposed mice than control group. CRE treatment significantly reduced the increase of PGE2/PGE1 ratio induced by CCS. Conclusion : These findings suggest that Coptidis Rhizoma may work as a potential agent to modulate inflammatory responses under the condition of cold adaptation formed by CCS.

Understanding and monitoring virus-mediated infections has gained importance since the global outbreak of the coronavirus disease 2019 (COVID-19) pandemic. Studies of high-throughput omics-based immune profiling of COVID-19 patients can help manage the current pandemic and future virus-mediated pandemics. Although COVID-19 is being studied since past 2 years, detailed mechanisms of the initial induction of dynamic immune responses or the molecular mechanisms that characterize disease progression remains unclear. This study involved comprehensively collected biospecimens and longitudinal multi-omics data of 300 COVID-19 patients and 120 healthy controls, including whole genome sequencing (WGS), single-cell RNA sequencing combined with T cell receptor (TCR) and B cell receptor (BCR) sequencing (scRNA(+scTCR/BCR)-seq), bulk BCR and TCR sequencing (bulk TCR/BCR-seq), and cytokine profiling. Clinical data were also collected from hospitalized COVID-19 patients, and HLA typing, laboratory characteristics, and COVID-19 viral genome sequencing were performed during the initial diagnosis. The entire set of biospecimens and multi-omics data generated in this project can be accessed by researchers from the National Biobank of Korea with prior approval. This distribution of large-scale multi-omics data of COVID-19 patients can facilitate the understanding of biological crosstalk involved in COVID-19 infection and contribute to the development of potential methodologies for its diagnosis and treatment.
