Science and technology (S&T) is one of the most important elements in a nation's competitiveness. In an effort to strengthen their national competitiveness, all countries are focusing on upgrading the level of eir S&T. With these factors in mind, Korea has increased its support of national research and development (R&D). In recent years, this added support has resulted in an increased interest in the effectiveness of R&D. We have made continuous efforts to enhance the accountability and effectiveness of R&D by strengthening performance evaluation and considering R&D evaluation results during the budget review (appropriation) process. In order to change to a performance based system, we need to develop objective and scientific indicators to measure and evaluate the quality of the research performance of R&D programs. One of the primary research outcomes is publications. The impact factor of publications is widely used to evaluate overall journal quality and the quality of the papers published therein. However, the use of impact factors has been criticised because they can vary greatly when works from different subject areas are compared. In order to overcome this limitation, we have developed three kinds of qualitative indicators, which are functions of the impact factor. Two of these qualitative indicators, Modified Rank Normalized Impact Factor and Ordinal Rank Normalized Impact Factor, are based on order statistics (rank) for all journals from a specific specialty. The third qualitative indicator, Relative Field Impact Factor, uses the average impact factor of all journals within a subject category. We also suggest a quantitative indicator, Percentage of Contribution. In this study, we suggest 4 indicators and use them to evaluate the performance of outcomes from three R&D programs supported by the Ministry of Education, Science & Technology. We also perform a simulation study to verify the effectiveness of the proposed indicators. It can be shown that the proposed Ordinal Rank Normalized Impact Factor is the most reliable and effective indicator for comparing research performance across subject categories. However, we recommend using previous indicators in combination with the proposed indicators in this study for the research evaluation of R&D programs.
Purpose - The purpose of this paper is to provide a political registration point for analyzing the economic impacts on the national economy from the REITs distribution industry in our country. The REITs distribution industry was introduced in 2001 to accelerate the corporate restructuring process and advance the real estate market. During its establishment, the REITs distribution industry faced difficulties; however, the industry grew rapidly through interest from institutional investors, thus mitigating the establishment problems by 2006. In Korea, more than 108 REITs were operating as of the end of June 2015. REITs contribute significantly to the national economy. The economic impacts on the national economy of the REITs distribution industry was analyzed using input-output (I-O) analysis with respect to production, imports, value-added, and employment. Research design, data, and methodology - The research used an I-O analysis of the activities of the REITs distribution industry in the national economy. The I-O analysis methodology analyzes the economic effects that influence other industries with respect to one unit of external investment. The data for this analysis were the I-O table of 2013 as published by the Bank of Korea in 2014. Results - The findings of this study are as follows. First, if an external input to the REITs distribution industry is 1 won, the overall impact of the product is 1.3869 won, the import induction is 0.0002 won, and the value-added induction is 0.7656 won. A new investment of 659.9 billion won into the REITs industry was estimated to produce a gross effect of 915.2 billion won. Second, if an external input to the REITs distribution industry is 1 billion won, the employment-inducing effects are estimated at 19.6394 individuals. The employment-inducing coefficient of 19.6394 for the REITs distribution industry indicates that the industry created significant employment-more than other industries-because the coefficient was 2.2 times the 2013 industry average employment-inducing coefficient of 8.8. Third, the investment effects of the REITs distribution industry on production induction, value-added induction, and employment induction are assumed to be large in business support services, financing, communications and broadcasting, and professional, scientific, and technical services. Conclusions - The REITs distribution industry was analyzed as having a strong employment inducing, high value added effect. The REITs distribution industry is an excellent alternative for the government authority to create multilateral jobs. Because the REITs distribution industry has a significant positive impact on the national economy, it should be developed. However, the I-O methodology has restrictions with respect to the fixation and timing of the input coefficient. Follow-up research is expected to supplement the analysis method at a specific point in time.

This study investigated the current tendency of the middle school student's use of the food and nutrition information from the internet web site. The research employed web survey for the national middle school students. Middle school students usually searched the internet information to do homework and to solve the own curiosity. Forty percent of respondents had experience to get food and nutrition information from tile internet, and 74% of them were girl. Cooking method and world cooking exploring were the most wanted information among food and nutrition information. Professional cooking site and tips of food and nutrition from study aiding sites and monthly magazine sites were tile resources of food and nutrition information. The mai or reasons for searching the food and nutrition information were to know the cooking method and out of curiosity. The most unsatisfied problems were unnecessary information, too much advertisement and too difficult contents when the users approached the site to get the food and nutrition information. Students who have been not interested in and had no homework about food and nutrition, had no visiting experience of web sites for food and nutrition information. Therefore, to provide food and nutrition information for teenagers through internet, web sites were developed to have easy contents linked to study aiding site or other sites that teenagers frequently visit. Since teenager's interest about health issues is not as high as adult's one, the contents of sites must be easy for teenagers to follow and fun, however, should be based on scientific facts on food, nutrition and disease.
Background: Because of climate change, interest in the development of carbon pools has increased. In agricultural ecosystems, which can be more intensively managed than forests, measures to control carbon dioxide ($CO_2$) emission and absorption levels can be applied relatively easily. However, crop residues may be released into the atmosphere by decomposition or combustion. If we can develop scientific management techniques that enable these residues to be stocked on farmland, then it would be possible to convert farmlands from carbon emission sources to carbon pools. We analyzed and investigated soil respiration (Rs) rate characteristics according to input of carbonized residue of red peppers (Capsicum annuum L.), a widely grown crop in Korea, as a technique for increasing farmland carbon stock. Results: Rs rate in the carbonized biomass (CB) section was $226.7mg\;CO_2\;m^{-2}h^{-1}$, which was 18.1% lower than the $276.9mg\;CO_2\;m^{-2}h^{-1}$ from the red pepper residue biomass (RB) section. The Rs rate of the control was $184.1mg\;CO_2\;m^{-2}h^{-1}$. In the following year, Rs in the CB section was $204.0mg\;CO_2\;m{-2}h^{-1}$, which was 38.2% lower than the $330.1mg\;CO_2\;m^{-2}h^{-1}$ from the RB section; the control emitted $198.6mg\;CO_2\;m^{-2}h^{-1}$. Correlation between Rs and soil temperature ((Ts) at a depth of 5 cm) was $R^2=0.51$ in the RB section, which was higher than the other experimental sections. A comparison of annual decomposition rates between RB and CB showed a large difference, 41.4 and 9.7%, respectively. The results showed that carbonization of red pepper residues reduced the rates of decomposition and Rs. Conclusions: The present study confirmed that the Rs rate can be reduced by carbonization of residue biomass and putting it in the soil and that the Rs rate and Ts (5 cm) were positively correlated. Based on the results, it was determined that approximately $1.2t\;C\;ha^{-1}$ were sequestered in the soil in the first year and $3.0t\;C\;ha^{-1}$ were stored the following year. Therefore, approximately $1.5t\;C\;ha^{-1}year^{-1}$ are expected to be stocked in the soil, making it possible to develop farmlands into carbon pools.

The purpose of this study was to analyze pre-service teachers' reflective discussion on their practical work-based teaching by focusing on the components of instruction and the connectivity of discussion. Eight after-class discussions were recorded and transcribed, and finally analyzed in terms of theoretically driven categories such as aims, teacher knowledge and learner response which also respectively reflect the actual flow of planning, implementation and evaluation of the teaching practice. The result showed that in their discussion about students, conceptual understanding and scientific skill components were most emphasized, while teaching method and strategy were most frequently addressed in the discussion about teacher knowledge. But this also revealed problems in their discussions such as the lack of discussion about inquiry and student interest, difficulties in clarifying theoretical terms and the lack of discussion about instructional models and theories. Meanwhile, pre-service teachers' discussions were limited in terms of connectivity between the components of instruction, meaning that their discussion tended to deal with each component separately rather than occurred in connection with each other. Furthermore, when connections were made during the discussion, only few components of instruction appeared. Based on this result, the paper suggests the need to develop tools to facilitate effective reflection in ways that incorporate various components of instruction and enhance connectivity between the components and between the instructions.
Objectives : Currently, it is being reported that new health technology (HT) is introduced and spread throughout Korea at a very fast rate. However, the current status of new HT related to dentistry has not been known or studied. Therefore, this study aims to understand the present state and awareness on dentistry-related domestic new HT via surveys and research, and thus apply this as a reference to construct an effective new HT-related system in the field of dentistry. Methods : The assessment status of New Health Technology Assessment (nHTA) committee was searched on the website for any updates on new HT5). The cases were searched in the range between Jan 1 2012 and Jul 31 2016 by submission date and were analyzed by year, division of technology, progress and major operating practitioner. Among those, technologies utilized by dentists were additionally analyzed. The survey result was obtained by combining responses of 25 participants from the workshop for new HT application and 11 members of Korean Association of Oral and Maxillofacial Surgeons (KAOMS). The workshop was co-hosted by KAOMS and Clinical Translational Research Center for Dental Science (CTRC) under Seoul National University Dental Hospital (SNUDH). Results : Most of the respondents to the survey have heard of new health technology but were unaware of the application procedure. 'Safety and effectiveness' was selected the most for things to consider when introducing new HT, followed by 'scientific evidence of the technology.' For new dental HT status, submissions between 2012 and Jul 31 2016 were analyzed by major operating practitioner, including cases where there are multiple practitioners. Yet, only 19 cases (17 %) of dentists were reported. Among 385 cases approved by nHTA, only 2 cases included dentists. Conclusions : Active publicity by the government on new HT and its application procedure, and continued interest and research in the dental and medical community is likely to be required for the development of dentistry.

This study aims to provide basic materials for marketing strategies of cosmeceuticals by investigating customers' recognition and satisfaction about cosmeceuticals targeting 161 adult men and women in their 20s to 50s and living in Seoul, Korea and then analyzing what should be improved for customers. According to the survey, many customers prefer cosmeceuticals due to the professionalism recognized by hospitals, the recommendation by doctors and the scientific image, though the recognition about cosmeceuticals is low among customers in their 40s or older because they are unfamiliar with the term. The survey also shows that the satisfaction about cosmeceuticals is very high in that 94.41% out of 49.85% total users said they were willing to repurchase them, while 72.22% out of 50.15% total nonusers said they wanted to purchase them. The greater knowledge about skin, the higher the interest in cosmetics and the aesthetic practice rate. When it comes to comparing cosmeceutical users and nonusers in choosing cosmetic products, the greater knowledge about skin, more nonusers consider brand recognition (r=.222, p<.05) and cosmetic ingredient (r=.245, p<.005); and more users convenience (r=.162, p<.05). Now that total customers' awareness of cosmeceuticals remains low yet, therefore, it is considered necessary to steadily promote them, enhance repurchase factors, and come up with strategies differentiated from ordinary cosmetics.
