This study compared the physicochemical characteristics, proximate composition, taste compound and antioxidant properties of Sikhye prepared with pigmented rice. Proximate composition showed a significant difference depending on the type of pigmented rice except crude fat contents and pH, color was a significant difference depending on the type of pigmented rice. The highest brix degree was $15.07^{\circ}Brix$ in red and black rice Sikhye. Each highest value of reducing sugar and free sugar content showed milled rice and brown rice Sikhye. Titratable acidity and total acidity of the pigmented rice Sikhye were highest for black rice Sikhye, free sugar content were highest for green rice Sikhye. Analysis of their relative antioxidative properties indicated that black rice Sikhye had the highest total polyphenol, flavonoid, and anthocyanin content, the highest levels of DPPH radical scavenging ability, and the highest level of reducing power and ferric reducing ability of plasma scores. Principal component analysis suggested that black rice Sikhye had a strong association with antioxidant properties, brown and red rice Sikhye had the strongest association with the sweetness and unique flavor.

This study was conducted to investigate the effects of dietary quercetin on growth performance, blood biochemical parameters, immunoglobulin, and blood antioxidant activity in broiler chickens. Three hundred twenty one-day old Ross broilers were divided 8 treatments (C(-), basal diet; C(+), basal diet with antibiotics; vitamin E 20 IU; vitamin E 200 IU; quercetin 20 ppm; quercetin 200 ppm; methoxylated quercetin 20 ppm; methoxylated quercetin 200 ppm) with 4 replicates and 10 birds per replicate. Birds were reared for 35 days and their feed intake and weight gain were measured weekly. At 35d, eight birds of average weight from each replicate were selected for blood collection and analysis. Weight gain of birds in the groups fed quercetin was higher when compare to NC but there was no significant difference. In the serum, creatinine, BUN and AST in quercetin groups significantly decreased compared to those of control (NC and PC) (P<0.05). The contents of IgA and IgM were significantly lower in quercetin groups than those of NC (P<0.05). SOD like activity and MDA content tended to decrease in quercetin groups, however, there was no significant difference among treatments. In conclusion, supplemental quercetin to poultry diet could be positive aspect on performance and blood metabolites. Optimum adding levels was more than 20 ppm.

As the need for anti-terrorism legislation has been continuously argued, Anti-terrorism act has been enacted and enforced. On the other hand, there still remain a lot of points to be discussed regarding the definition of the concept of terrorism, matters of human rights violations, strengthening authority of the investigation and intelligence agencies, and mobilization military forces for the suppression of terrorism. Also, reviewing Anti-terrorism act and its enforcement ordinance draft, this legislation seems to regulate terrorist groups like IS. If so, in the case of terrorism of North Korea or domestic anti-government organizations, whether this law would be applied could become an issue. In the case of terrorism of North Korea, Ministry of National Defense has a right of commandership in the military operations, however, it is also possible to apply the article 4 of Natural Security Act a crime of performing objective-or a crime of foreign exchange on Criminal law as legal grounds for not military terrorisms but general investigations. Therefore, it is necessary to involve consideration about this matter. Furthermore, in the view of investigation, Anti-terrorism act and its enforcement ordinance draft do not mention Supreme Prosecutors Office and Ministry of Justice that conduct investigations. In the case of terrorism, the police and prosecution should conduct to arrest criminals and determine crimes at the investigation stage, however, any explicit article related to this content in Anti-terrorism act and its enforcement ordinance draft was unable to be found. Although Anti-terrorism act is certainly toward preventive aspects, considering some matters such as prevention, actions on the scene, maneuver after terrorism, arresting terrorists, investigation direction, cooperation, and mutual assistance, it is necessary to reflect these contents in Anti-terrorism act. In other words, immediately after terrorists attacks, it is possible to mobilize the military operations by Integrated Defense act in order to arrest them in the case of military terrorism. Nevertheless, because both military terrorism and general one are included in the investigation stage, it needs to begin an investigation under the direction of the prosecution. Therefore, above all, a device for finding out the truth behind the case at the investigation stage is not reflected in the current Anti-terrorism act and its enforcement ordinance draft. Accordingly, if National Intelligence Service approaches information at the prevention level in this situation, it may be necessary to come up with follow-up measures of the police, the prosecution, and military units.

This study contemplates the tendency of the examination questions for History of Korean Landscape Architecture. The study targets the questions of 'Landscape Architecture History' which has been set in the written test for National Qualification Test of a landscape engineer for recent 10 years from 2005 to 2014 and derives analyzable items based on the guidelines of question-setting presented by Human Resources Development Service of Korea. The results of the study are drawn as follows. First, among 5 areas composing Landscape History, the proportion of Korean Landscape questions is getting increased while that of Western ones is decreasing. Second, about 30 traditional trees and 11 types of traditional landscape elements including traditional facilities were shown in Korean Landscape questions. Besides, history, geographic, practical science, horticulture, anthology books and the 25 tradition landscape-related historic documents categorized as the garden painting data were found. And the kings from ancient era to Choseon Dynasty who were associated with the time of palace garden building, the builders or owners of the villas, the authors of the document and Chinese scholars also appeared. Third, there were no the questions of prehistoric times and Balhae Kingdom, whereas those of Choseon Dynasty were dominantly focused. Among the traditional sites of Choseon Dynasty, Byeolseo(villas) were set most, followed by Dosung or Gung-gweol(castle towns or palaces), houses, Nu Jeong Dea(pavilions) and Seowon(local schools) in order. Nak-an eupseong and Yong-ju sa were the only cases for a castle town and a temple each. Fourth, being associated with tradition spaces, the questions asked for understanding the detailed contents of time of sites' construction, builders, location features, building structures, ground plan types and the components s of garden. In addition, as a result of checking whether traditional landscape sites were shown in the set questions in 9 Korean Landscape textbooks, Dongchundang, Pungamjeonsa, Simgogseowon did not appeared. As a result of reviewing the tendency of the examination questions for History of Korean Landscape Architecture, the questions which ask minor facts without generality and which include difficult information and site uncomprehended in the textbook should be reconsidered.

How can new media devices and networks provide an effective response to the world's growing sector of cultural and historically-minded travelers? This study emerged from the question of how mobile handsets can change the nature of cultural and historical tourism in ubiquitous city environments. As wireless network and mobile IT have rapidly developed, it becomes possible to deliver cultural and historical information on the site through mobile handset as a tour guidance system. The paper describes the development of a new type of mobile tourism platform for site-specific cultural and historical information. The central objective of the project was to organize this cultural and historical walking tour around the mobile handset and its unique advantages (i.e. portability, multi-media capacity, access to wireless internet, and location-awareness potential) and then integrate the tour with a historical story and role-playing game that would deepen the mobile user's interest in the sites being visited, and enhance his or her overall experience of the area. The project was based on twelve locations that were culturally and historically significant to Korean War era in Busan. After the mobile tour game prototype was developed for this route, it was evaluated at the 10th PIFF (Pusan International Film Festival). After use test, some new strategies for developing mobile "edutainment content" to deliver cultural historical contents of the location were discussed. Combining 'edutainment' with a cultural and historical mobile walking tour brings a new dimension to existing approaches of the tourism and mobile content industry.

The purpose of this study was to investigate the elementary school teachers' perception of science writing. In this study, 10 elementary school teachers who have taught in the 3rd or 4th grade science lesson in 2010 were selected. Researchers constructed interview guide in three parts including the teachers' understanding of science writing, the status of science writing teaching and the difficulties of science writing in their classes. For the investigation, semi-structured in-depth interviews with 10 elementary school teachers were conducted individually. The results showed that the elementary school teachers were unfamiliar with the word ‘science writing’ and considered science writing as a writing using science learning contents. Also, they think that teaching science writing in their science lessons was not needed and didn't assess and provide detailed feedback with the students' written works. Most teachers needed teaching materials and assessment tools for science writing. To develop elementary teachers' understanding of the value and use of writing for learning in science, they will need to participate in science writing programs for in-service teachers and various teaching materials and assessment tools should also be developed.

Modern society has been exposed to various dangers and crimes in the process of globalization, informationization, decentralization etc. along with the development of material civilization under rapid changing societal environment. These factors are exerting a lot of effects in public security environments, as result there are gradual interest about crime and crime prevention. Realization of responsibility who take charge of social safety, from public security to private security, appears important topic at the moment. The positive point of view which private security industry is responsible to cope with security spheres instead of public security has been emerged from the reason that the public security has limitation to solve security problems for themselves. It is the time to make effort to compromise the public security and the private security industry to forecast social change and prevent dangers in the advance. In Korea, there has been close cooperation between public security and private security for decades. Strongly emerging and interesting sphere is "Private Investigation(Private Detective)" in Korea at present. There has been some proposed legislations of private investigation for decreasing burden of public security and social sympathy about possibility of private investigation system is increasing now. In this study, we focused on the introduction of private investigation system through the analysis of bill proposals for last 14 years, for instance historical aspects, contents, the differences among bill proposals. Among these, a comparison on bill proposals of the 19th National Assembly's during 2012 - 2013 were analysed mainly. We examined the importance point at issue items for introduction of private investigation system. Suggestions for introduction of private investigation system is as follows. The necessity of independent bill for developmental private investigation system is needed and the main body should be a juristic person instead of a individual for the public interest and responsibility. For the good service of private investigation and to prevent the unqualified person become a private investigator, the recruiting system and examination of private investigator should be prepared well and take into consideration anticipated problems. Also the necessity of definite jurisdiction department's appointment to divide responsibility in operation.

The objective of this research was to confirm the difference in physiological responses to environmental stresses such as chilling, high temperature, NaCl, and chemical stress (paraquat) in Protox inhibitor resistant-transgenic rice (MX, PX, and AP37) and its non-transgenic counterpart (WT). Transgenic and non-transgenic rice plants were exposed to a chilling temperature of $5^{\circ}C$ for 1 day or a high temperature of $45^{\circ}C$ for 4 days and allowed to recover at $25^{\circ}C$ for 6 days after the chilling treatment or 8 days after the high temperature treatment. Leaf injury, shoot fresh weight, porphyrin biosynthesis substances, and chlorophyll content were investigated in transgenic and non-transgenic rice at 6 days after 0.5% and 1% NaCl treatments or at 5 days after 0~300 ${\mu}M$ paraquat treatments. No significant difference in leaf injury and shoot fresh weight were observed between transgenic and non-transgenic rice during chilling and recovery. Plant height and shoot fresh weight were also similar between transgenic and non-transgenic rice during the high temperature and recovery period (0~5 days). However, plant height and shoot fresh weight in transgenic rice line MX and PX were lower than in non-transgenic rice at 6 days for recovery. Leaf injury, chlorophyll, and Mg-Proto IX ME contents had no significant difference between transgenic rice and non-transgenic rice after NaCl treatment, but Proto IX content for AP37 and shoot fresh weight for PX and AP37 in 0.5% NaCl treatment were significantly reduced compared with non-transgenic rice. There was no difference in leaf injury and shoot fresh weight when comparing transgenic rice and non-transgenic rice after paraquat treatment. Although transgenic rice and non-transgenic rice showed a little difference at a particular measurement period in certain environmental stresses, there was generally no difference in physiological responses between transgenic rice and non-transgenic rice.

This study was designed to evaluate antioxidant activity of low-quality Codonopsis lanceolata treated by fermentation process followed by hydraulic high pressure extraction. C. lanceolata was subjected to 5,000 bar for 30 min at $25^{\circ}C$. The highest phenolics content was observed in the combined treatment of fermentation and high pressure extraction (35.11 mg/100 g), followed by high pressure extraction alone (14.78 mg/100 g) and conventional extraction (14.56 mg/100 g). The content of flavonoids followed the similar pattern as that of total phenolics, showing 280.86 mg/100 g of C. lanceolata treated by the combined fermentation with high pressure extraction whereas 193.05 mg/100 g of C. lanceolata treated by the conventional extraction. The DPPH scavenging activity was 69.32% at 0.6 mg/mL of C. lanceolata treated by the combined process, while the DPPH scavenging activities of C. lanceolata treated by high pressure extraction alone and the conventional extraction were 60.35% and 30.92%, respectively. The highest reducing power of C. lanceolata extract (1.0 mg/mL) was observed at the combined treatment (0.926), followed by high pressure extraction alone (0.881) and the conventional extraction (0.733). The combination of fermentation with high pressure extraction significantly increased the contents of phenolics and flavonoids and also enhanced the antioxidant activity. Therefore, the combined application of fermentation and high pressure extraction can be an alternative technique for the extraction of C. lanceolata. These results provide useful information for enhancing biological properties of low-quality C. lanceolata.
