Many of the world's large ecosystems are severely stressed due to population growth, water quality and quantity problems, vulnerability to flood and drought, and the loss of native species and cultural resources. Consequences of climate change further increase uncertainties about the future. These major societal challenges must be addressed through innovations in governance, policy, and ways of implementing management strategies. Science and engineering play a critical role in helping define possible alternative futures that could be achieved and the possible consequences to economic development, quality of life, and sustainability of ecosystem services. Science has advanced rapidly during the past decade with the emergence of science communities coalescing around 'Grand Challenges' and the maturation of how these communities function has resulted in large interdisciplinary research networks. An example is the River Experiment Center of KICT that engages researchers from throughout Korea and the world. This trend has been complemented by major advances in sensor technologies and data synthesis to accelerate knowledge discovery. These factors combine to allow scientific debate to occur in a more open and transparent manner. The availability of information and improved communication of scientific and engineering issues is raising the level of dialogue at the science-policy interface. However, severe challenges persist since scientific discovery does not occur on the same timeframe as management actions, policy decisions or at the pace sometimes expected by elected officials. Common challenges include the need to make decisions in the face of considerable uncertainty, ensuring research results are actionable and preventing science being used by special interests to delay or obsfucate decisions. These challenges are explored in the context of examples from the United States, including the California Bay-Delta system. California transfers water from the wetter northern part of the state to the drier southern part of the state through the Central Valley Project since 1940 and this was supplemented by the State Water Project in 1973. The scale of these activities is remarkable: approximately two thirds of the population of Californians rely on water from the Delta, these waters also irrigate up to 45% of the fruits & vegetables produced in the US, and about 80% of California's commercial fishery species live in or migrate through the Bay-Delta. This Delta region is a global hotspot for biodiversity that provides habitat for over 700 species, but is also a hotspot for the loss of biodiversity with more than 25 species currently listed by the Endangered Species Act. Understanding the decline of the fragile ecosystem of the Bay-Delta system and the potential consequences to economic growth if water transfers are reduced for the environment, the California State Legislature passed landmark legislation in 2009 (CA Water Code SS 85054) that established "Coequal goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the Delta ecosystem". The legislation also stated that "The coequal goals shall be achieved in a manner that protects and enhances the unique cultural, recreational, natural resource, and agricultural values of the Delta as an evolving place." The challenges of integrating policy, management and scientific research will be described through this and other international examples.
This study reviewed the research in China on music interventions for adult brain injury patients. Eighty-three studies that met the inclusion criteria were included for analysis. Our review revealed that the number of intervention studies using music with adult brain injury patients has been on the rise since 2012, and random control research design methods have been dominant. Studies focused on the physical domain and emotional domain together were most common. Researchers in fields outside of music therapy conducted 43 of the studies, and music therapists carried out 14 of the studies as intervention providers. Most of the studies carried out by experts in fields other than music therapy used listening activities involving preexisting recorded music. However, most of the studies conducted by music therapists adopted reconstructed music and played it live during their intervention. The specificity of the described content of the interventions and level and relevance of stated rationale to the target goal of the intervention suggests that high quality of intervention was conducted with a therapist/investigator who has completed adequate professional education/training, which would emphasize the importance of music therapy professionalism. This study provides the baseline data for how music intervention research has been implemented in China and presents implications for future clinical practice and research.
Purpose: As the internet use of teenagers become more common, the need for research on the relationship between the internet and youth depression has emerged. The purpose of this study is to investigate the relationship between internet use and adolescent depression. Methods: The subjects of this study were youth attending elementary($6^{th}$ grade), middle($2^{nd}$ grade), and high schools($2^{nd}$ grade) belonging to the Busan Metropolitan City Office of Education. Depression was assessed using the BDI depression scale. Internet functions were classified into 10 categories, and the degree of use by Internet functions was examined. The most frequently used Internet sites were surveyed. Univariate analysis using $X^2$ test and multivariate analysis using logistic regression analysis were conducted to find out the difference of internet and smartphone media function on depression according to elementary, middle and high school students. Results: Depression was higher of 13.2 times for students who use online transactions (goods purchase), 0.07 times for students who use 'bulletin board' activities in elementary students. Depression was higher of 1.55 times for those who use online transactions (purchasing goods), and 2.3 times for those who use adult sites for middle school students. Depression was higher of 2.1 times when using e-mail and 1.9 times when using other information retrieval for high school students. Conclusion: It is necessary to consider characteristics of internet utilizing pattern by school class in policy regulation and prevention program to reduce youth depression.

Japanese sumac (Rhus javanica) is one of the common herbaceous plants growing over the country. This study was conducted to investigate the extraction characteristics and physiological activities inluding nitrite scavenging ability of the water extracts from leaf, fruit and bark of Japanease sumac. Extraction yield was 6.62~13.84%, free amino acids were detected as 24 kinds with 37.9 mg/100g in leaf extract, 23 kinds with 27.0 mg/100g in fruit extract and 27 kinds with 39.0 mg/100g in bark extract, respectively, and seven kinds essential amino acids were detected. Total contents of flavonoids equivalent to naringin were 587.2 mg/100g in bark extract, 557.3 mg/100g in fruit extract and 379.9 mg/100g in leaf extract, respectively. Total contents of phenolics equivalent to gallic acid were 111.2 mg/100g in leaf extract, 108.4 mg/100g in fruit extract and 80.4 mg/100g in bark extract, respectively. The nitrite scavenging ability of extracts was order of 61.93% in bark extract>57.38% in fruit extract>55.49% in leaf extract, and was 78.1~100% of those of BHT (butylated hydroxytoluene) equivalents at pH 1.2. The electron donating ability was order of 47.38% in fruit extract>43.06% in leaf extract>38.55% in bark extract, and was compared to 65.6%, 58.8% and 53.6% of those of BHT equivalents, respectively. The reduction power was evaluated to 37% higher in leaf extract, 43% higher in fruit extract and 46% higher in bark extract than those of BHT equivalents. The metal chelating ability of extracts was considerably low and was order of 27.3% in bark extract>20.6% in leaf extract>11.2% in fruit extract.

This study aims to analyze the direction of the reading education programs based on the 2015 revised curriculum and to seek the plans for the school library and the teacher librarian to be able to contribute them. For this purpose, the types of school-based reading education programs in the report of 100 excellent school curriculum in 2016, which was first applied by the amended curriculum were analyzed through multiple intelligences. Upon the analysis results, the reading education programs in the schools showed to be operated with interpersonal Intelligence. Community-aligned reading was the most frequently operated in the primary schools while student reading club activities were the most common in the middle and high schools. In case of reading education program related to linguistic intelligence, the most commonly operated ways were reading books, writing with literatures, and writing book report, in primary, middle, and high schools, respectively. In case of reading education program related to spatial intelligence, media production type showed the most commonly operated in all types of schools. However, there was no reading program related to naturalist intelligence. Based on these analysis results, the plans to contribute the activation of reading education programs by school libraries under the 2015 amended curriculum were suggested in the aspects of development of connection programs with teachers, students and parents as the center of education community, installation and operation of maker spaces and enhancement of program management and inquiry-based learning competency of teacher librarians.

Purpose: Upper respiratory tract infections are major causes of the common cold throughout the world. Cordyceps militaris (C. militaris) is a well-known functional food for its anti-fatigue and immunomodulating activities. On the other hand, there are no reports on the protective effect against upper respiratory tract infections (URI). This study was a 12 week randomized, double-blind, and placebo-controlled trial in healthy volunteers. Methods: A total of 100 subjects 20 ~ 70 years of age with a history of at least two colds in the year were enrolled in the study. The participants were required to record any adverse events and rate any cold-related incidents in a diary during the investigation period. The efficacy end point was the symptoms and incidence of URI, and changes in cytokines, IgA and natural killer (NK) cell activity. Results: The Cordyceps militaris group over 12 weeks showed no significant impact on the incidence and symptomatology of URI compared to the placebo group. On the other hand, the experimental group showed significantly higher NK cell activity (p = 0.047) and IgA level (p = 0.035) compared to the placebo group. The NK-cell activity and IgA level were increased significantly by Cordyceps militaris over 12 weeks. Conclusion: The results suggest the possible beneficial immunomodulating effects, but the protective effects on URI could not be demonstrated under these conditions. Additional research will be needed to determine the efficacy and mechanisms of Cordyceps militaris function.
This study examined the meanings of the disability education of the mothers who reared their children with brain lesions. For this purpose, Rennie's hermeneutic grounded theory was applied and the consented 7 mothers participated in this study. With the in-depth interviews, 53 meaning units, 16 subordinate categories and 7 hermeneutic categories were classified. These 7 hermeneutic categories were 'wailing miserably everyday', 'social mobilization of the surroundings', 'straight forward', 'smash rock with the eggs', 'looking at a faraway', 'learning together' and 'subjectivation of disability education.' The experience of disabled children education process was concurrent experience of frustration and hoping that moving toward a big hope through the resignation stage, the chasing stage, the vision stage, the challenge stage, and the small achievement stage. Repetitive common patterns of behavior revealed three types: wishy-washy type, realistic-strategy type, and indomitable-challenge type. Moreover, the core category of educational experience was concluded to be 'a pedagogical process of turning despair from severe disabilities into hope through education.' Based on the analysis results, concrete intervention plans for social welfare practice were suggested to support the disabled children's lives with high quality of education.
Wound care is a health industry concern affecting millions worldwide. Recent increase in metabolic disorders such as diabetes comes with elevated risk of wound-based complications. Treatment and management of wounds are difficult practices due to complexity of the wound healing process. Conventional wound dressings and treatment applications only provide limited benefits which are mainly aimed to keep wound protected from external factors. To improve wound care, recent developments make biopolymers to be of high interest and importance to researchers and medical practitioners. Biopolymers are polymers or natural origin produced by living organisms. They are credited to be highly biocompatible and biodegradable. Currently, studies reported biopolymers to exhibit various health beneficial properties such as antimicrobial, anti-inflammatory, hemostatic, cell proliferative and angiogenic activities which are crucial for effective wound management. Several biopolymers, namely chitosan, cellulose, collagen, hyaluronic acid and alginic acid have been already investigated and applied as wound dressing agents. Different derivatives of biopolymers have also been developed by cross-linking with other molecules, grafting with other polymers, and loading with bioactive agents or drugs which showed promising results towards wound healing without any undesired outcome such as scarring and physiological abnormalities. In this review, current applications of common biopolymers in wound treatment industry are highlighted to be a guide for further applications and studies.
Since the establishment of the Korean Society of Plant Taxonomists (KSPT) on Dec. 13, 1968, the professional manpower training and research activities have been analyzed. The survey method was based on the homepage of the KSPT and the Korean J. Pl. Taxon, and on data provided by each university about professional manpower. Over the past 50 years, a total of 680 specialists in plant taxonomy have been trained, consisting of 537 master's degree holders (274 males, 263 females) from 30 universities and 143 PhDs (97 males, 46 females) from 26 universities, and the number has increased significantly since 1998. With regard to changes in the field of research over the last ten years, revision papers were the most common in the period of 1988-1997 (72%), but this rate has decreased to 51% over the last ten years, while the number of unrecorded papers has increased to 28%. In the 629 revision papers on taxa, 49% of the taxa belong to Asteraceae, Ranunculaceae, Cyperaceae, Liliaceae, Rosaceae, Fabaceae, Apiaceae, Lamiaceae, Orchidaceae, Oleaceae, Euphorbiaceae, Polygonaceae, and Amaryllidaceae. With regard to changes in research methods, the number of morphological papers increased from 6% to 51%, while pollen papers have decreased from a rate of 20% to only 2%. Chromosome studies account for 3-4%, chemotaxonomic studies 2%, and DNA studies remain low at 3-16%. The percentage of papers in English now stands at 43%, mainly due to the increased number of papers on unrecorded species.
Common issues in research and policy on cultural heritage can be extracted among Eurasian countries although countries in the region show different colors of policies and studies. Among them one thing peculiar to Central Asian countries is that in general they do not have well delineated laws and regulations on the protection of cultural heritage. It may be because they had no enough time and experience to legislate and implement relevant laws and regulations ever since they got independence. Research on cultural heritage in Central Asian countries is often made in cooperation with foreign institutions. As shown in archaeological excavation projects in Central Asian countries, cooperative projects exceed noncooperative ones in terms of size and longevity. UNESCO, through its projects on the Serial and Transboundary World Heritage Nomination of the Silk Roads in Central Asia, also supports countries in Central Asia and others along the Silk Road in order to facilitate inclusion of their cultural heritages in the Tentative List of the World Heritage. With regard to activities on the protection of cultural heritage, while respective countries in Central Asia have made good efforts, they could not produce effective outcomes due to short of budget and specialized manpower. They have rich resources of cultural and documentary heritage but their registered heritages on the UNESCO's World Heritage List and Memory of the World are under-represented because of short of technology and experience among other things. A new trend in cultural heritage studies that combined cultural heritage with tourism has merged in recent years. While some critics have raised some negative questions, this new fashion became popular and will continue with the support of governments of Silk Road countries. In conclusion, Korean institutions are further encouraged to organize cooperative networks for research and policy with respective Eurasian countries.
