As modern buildings grow to become diversified, toxic gases and smoke coupled with characteristics of space during a fire increase the risk of large-scaled disaster. It is now urgent to take measures for evacuation and escape directly linked to personal damage. Existing fixed one-way emergency exit light is not enough for efficient evacuation and rescue. Therefore, to ensure quicker escape and evacuation during a fire, two-way radio data system should be devised, which linked with fire detector, helps people in danger to escape quickly and is able to control by a central control system, and the system was found to enhance the efficiency of escape and contribute to safer escape.

This study intended to develop a motorcycle safe vest that can be prepared against accidents by mounting a smart module (with built-in sensor) on the safe vest in order to emphasize safety among functional aspects of the motorcycle clothing. The research method investigated professional books, prior research, and Internet data to examine the characteristics of motorcycle wear and the theoretical examination of smart wear, and analyzed the functional characteristics of the design by reviewing smart jacket and vest design cases for motorcycles currently on the market. As a results of study an interface device sensor, which contains a sensor with IMU(Intertial Measurement Unit) and CPU(Central Processing Unit), was inserted into a motorcycle top in order to draw attention to the safety of motorcycle riders. The IMU sensor attached to the vest detected the tilting motion of the rider to either left or right side to obtain data on left or right direction, sudden stop, and so forth and displayed left or right turn signal and sudden stop sign on the backplate (back) through the LED module. As for charging the device to operate LEDs, a generator, which is designed to convert the heat energy in the exhaust into electric energy, was used to efficiently self-produce the power required to operate LEDs of the top while riding.

Purpose: This study identified effects of dietary and physical activity interventions including dietary interventions or physical activity interventions alone or combined dietary-physical activity interventions to improve symptoms in metabolic syndrome including abdominal obesity, high triglycerides, low high density lipoprotein cholesterol, elevated blood pressure, and elevated fasting glucose through meta-analysis. Methods: Articles on metabolic syndrome X published from 1988 to 2013 were searched through electronic databases, Google Scholar, and reference reviews. Methodological quality was assessed by the checklist, SIGN (Scottish Intercollegiate Guidelines Network). Results: In the meta-analysis, there were 9 articles reporting 13 interventions with 736 participants. Using random effect models, the dietary and/or physical activity interventions showed a lower mean difference in waist circumference ( - 1.30 cm, 95% CI: - 2.44~ - 0.15, p=.027). The combined dietary-physical activity interventions showed a lower mean difference in waist circumference ( - 2.77 cm, 95% CI: - 4.77~ - 0.76, p=.007) and systolic blood pressure ( - 5.44 mmHg, 95% CI: - 10.76~ - 0.12, p=.044). Additionally, interventions of over 24 weeks yielded a lower mean difference in waist circumference ( - 2.78 cm, 95% CI: - 4.69~ - 0.87, p=.004) and diastolic blood pressure ( - 1.93 mmHg, 95% CI: - 3.63~ - 0.22, p=.026). Conclusion: The findings indicate that dietary and/or physical activity interventions for metabolic syndrome reduce central obesity with no adverse effects. This finding provides objective evidences for dietary and physical activity management on metabolic syndrome as an efficient intervention.

The development of Technopolis and the establishment of innovative ecosystem have made an important contribution in South Korea's latest industrial development and economic growth. Particularly, Daedeok INNOPOLIS which is responsible for the central role in the national science technology advancement was founded as the Science Town in the 1970s. Since then, it has undergone three-phases of development: Science Park, Technopolis and Innovation cluster. As the result of the transition, Daedeok INNOPOLIS currently serve as the leading role for achieving sustainable economic growth, employment promotion, national and regional innovation. In order to accelerate the progress for success, Daedeok INNOPOLIS have arranged an opportunity for 21st century new industry development, improved growth of technology-intensive SMEs, reinforced academic-industrial cooperation, and established innovative ecosystem. Daedeok INNOPOLIS is considered as an outstanding case of endogenous development strategy of Technopolis. This study attempts to consider the endogenous development strategy of Technopolis in Korea through the analysis of development characteristics of Daedeok INNOPOLIS in two different perspectives: changes of spatial structure and establishment of innovation ecosystem. Daedeok INNOPOLIS have experienced a series of endogenous growth that is consisted of advancement strategy and structural changes, which allowed Daedeok research town to grow into an innovative cluster. A sign of growth of Daedeok INNOPOLIS became apparent when its strategy to reinforce the academic-industry cooperation system by promoting participation from universities helped to overcome a functional limitation as a research institute integrated for the establishment of innovative ecosystem. Since then, the center for creative economy and innovation established in cooperation with large enterprise, has a role to build a startup ecosystem and to promote next level of development such as proactive fostering of venture companies for sustainable technopolis development.

Since 2000, severe rots on aerial and underground parts of paprika( Capsicum annum L.) has occurred in most cultivation glasshouses throughout the country. Totally 169 isolates of a fungus were consistently isolated from the diseased plant tissues of fruits, stems, branches, and roots collected from 19 farms in six provinces. Anamorph stage of the fungus was identified as Fusarium solani based on morphological characteristics. However, the fungus readily produced sexual structure of perithecia on infected plant tissues and on agar medium. Since the fungus formed abundant perithecia by single isolate, it was considered as a homothallic strain of Nectria hematococn, the teleomorph of F. solani. Irregularly globose perithecia with orange to red color formed sparsely to gregariously on dead tissues of fruits and basal stems at the 3ate infection stage, which is a diagnostic sign for the disease. Abundancy of perithecium varied among isolates and they sized 125-220$\mu\textrm{m}$ in diam. Asci enveloping eight ascospores were cylindrical and measured 60-80x8-12$\mu\textrm{m}$. Ellipsoid to obovate ascospores are two-celled and measured 11-l8${\times}$4-7$\mu\textrm{m}$. Ascospores are hyaline, slightly constricted at the central septum, and revealed longitudinal striations that is a typical trait of the species. This fungus that has never been reported in Korea previously became a threat to paprika cultivation because of its strong pathogenicity and nationwide distribution.

Purpose: Mycobacterium abscessus belongs to the group of rapid-growing atypical mycobacterium. The organism is ubiquitous and is found in soil, dust, and water. Although it rarely causes disease in humans, Mycobacterium abscessus has been associated with soft tissue infection. To the best of our knowledge, this is the first case report of facial soft tissue Mycobacterium abscessus infection in a healthy child in Korea. Methods: A 12-year-old girl presented with an erythematous skin lesion with serous discharge on her chin, which had been present for 3 weeks. On her history, she had a laceration wound on her chin at public bath and the lesion was repaired at emergency department immediately. Although conventional soft tissue infecton treatment, her lesion remains unhealed state and had serous discharge for 2 months. Moreover, we found a 1 cm sized nodular mass on her chin. Therefore we performed excision operation and referred the specimen to the laboratory for microbial and histopathologic study. Results: Pathology report confirmed the mass was enlarged lymph node with chronic necrotizing granulomatous inflammation with central microabscess. Non-Tuberculous mycobacterium identification test through tissue specimen resulted Mycobacterium abscessus. We prescribed clarithromycin for three weeks by oral administration as well as performed wound debridement and mass excision via previous wound. This way, her lesion appeared to be complete healing with minimal scarring. There were no evidence of inflammation sign or palpable mass. Conclusion: Although the prevalence is rare, Mycobacterium abscessus infections of soft tissue should be considered even in a healthy child with a lesion caused by trauma or which fails to respond to conventional treatment.

We experienced the seven cases of penetrating and non-penetrating cardiac injuries combined with cardiac tamponade from June 1986 to June 1989 at Seoul and Chun-An Hospital of SOONCHUNHYANG medical college. The results were as follows. l. In sex distribution, 7 cases were male. In age distribution, The fourth decades occupied about 58 % of all cases. 2. In mode of injury, 4 cases were stab wounds, 1 case penetration by metallic fragment, 2 cases blunt chest trauma. 3. We routinely checked the CVP with subclavian vein catheterization in case of suspicious cardiac tamponade. Significant increments were showed in 4 cases. 4. Becks triad [low blood pressure, raised central venous pressure, distant heart sound] were recorded in 43 % of the cases with proven tamponades. 5. The sites of injury included RV in 4 cases, LV in 1 case, RA in 1 case and branch of RCA in 1 case. The RV injuries were the most common. 6. Coronary artery damage occurred in 2 cases. LADA was severed in 1 case combined with RV rupture and branch of RCA was torn 1 case. 7. Pericardiocentesis was performed 1 case at another hospital before referring to our hospital. We have never used the procedure because we think that it is potentially dangerous with no clear benefit. 8. Subxyphoid pericardial window was performed in 2 cases of severe cardiac tamponade. We have employed this method to stabilize the patients who had systolic hypotension. 9. Surgical approaches were performed with median sternotomy in 3 cases, thoracotomy in 4 cases. 10. We undertook the simple closure in 6 penetrating cardiac wounds. The removal of impacted metallic fragment was performed under the cardiopulmonary bypass. Simple ligation was performed in 2 cases of coronary artery severance 11. One patient with no sign of life was urgently intubated and undertaken an emergency room thoracotomy on the stretch car without antiseptic preparation. The cardiorrhaphy in 6 cases were performed in the operating theater 12. One patient undertaken emergency room thoracotomy did not survive due to refractory hypovolemic shock. But the remaining 6 patients recovered.

Simulacra theory as propounded by Jean Baudrillard in his seminal treatise, "Simulacra and Simulation," explores the significance of images, media and art in contemporary culture. Its central theoretical premise is the simulacrum, a sign or symbol that plays a crucial role in constructing perceived reality but which lacks a real-world referent. In Michel Gondry creates simulacra in the form of hallucinatory dream imagery by combining stop-motion animation and live-action elements. As experimental film-making that combines analog and minimum digital technologies, the result is a tour-de-force of synchronization. This study analyzes the film's technique and expressive content and, by adopting simulacra theory as a conceptual framework, aims to provide a better understanding of Gondry's work.

Damages on central nervous system induced by the exposure of microwave. However, the effects of microwave on ICP are not studied yet. The ICP affected by the condition of the brain has an significant effect on vital sign. So we investigated the changes of ICP of the rabbits after exposure. Twenty four rabbits were devided into 3 groups depending on the amount of exposure to microwave. One group was composed with 8 rabbits were exposed to microwave for 10 miniutes. Other were composed to microwave for 20 miniutes, 30 miniures, respectively. Intracranial pressure on each group were measured by subdural type ICP monitoring catheter immediately, first day, 3rd day, 5th day and 7th day after exposure of microwave. Results indicates that intracranial pressure of rabbits are not affected with statistical significance by exposure of microwave.

Experimental studies were performed to observe the difference in tolerance of small animals to oxygen poisoning, and also to examine the effects of certain drug for it. The three experimental groups consisted of mature rat group, immature rat group and mouse group. The animals were exposed to 5 atm. of 100% oxygen using hyperbaric chamber, and they were observed for oxygen poisoning by pulmonary and central nervous system manifestation. The tolerance to oxygen poisoning was represented by half fatality time in each experimental group. The drug applied was ammonium chloride $NH_4Cl$ and it was administered intraperitoneally in various dosages for particular attribution of its prophylactic effect. The following conclusions were made; 1. The immature rat group showed the higher degree of tolerance to oxygen poisoning, as evidenced by a more prolonged half fatality time in the group. No significant difference in the half fatality time between the mature rat and the mouse group was observed. 2. The fact that the immature group showed the higher degree of tolerance as compared with the mature rat group represented by delayed onset of convulsion. 3. There was a remarkable difference in the Lung Weight/Body Weight ratio between the experimental and control group. 4. The animals with a shorter half fatality time uniformally displayed an earlier onset of convulsive seizure as the sign of oxygen poisoning and a significant elevated Lung Weight/Body Weight ratio. 5. Ammonium chloride at the dosage of 450mg per kg body weight had the most pronounced prophylactic effect on oxygen poisoning.
