This study was attempted to seek the garden enjoyment of the Yang Un-geo etc., in the head house(宗宅) of Namwonyang's family and Jongho in Sunchang Gumiri through literature and field research. Admirers of Jongho were "six old Taoist hermit", including Cholo(楚老) Yang Un-geo(楊雲擧, 1613-1672) and Yangjindang Haman-ri, the author of Jongho-palgyeong, who was very close friends of Yang, as well as his son-in-law or out-law. Jonghojeong Pavilion, overland rock and nearby Takyeongjeong, which were built around a stone island shaped like a helmet, and a pool along the river, are known as 'Imcheonwonrim(林泉園林)' as the center of the custom that was conducted based on head house, which is up to 2km away from Jongho. Jongho-palgyeong is found to share the characteristics of Jeongja Palgyeong, which is based on Jonghoam, overland and Takyeongjeong, and the characteristics of the town's township of Namwonyang, Gumi-ri. The number of rock letters identified by the Mansutan members is a total of nine points, which clearly indicates that the scene was a scene where the custom of call to create poetry·fishing·playing musical instruments and drinking, as well as the scenery and landscape structure of the Jongho Palgyeong. Jongho Palgyeong, its customs and surrounding rock writing are highly suggestive and valid cultural views to remind or direct the old landscape of Mansutan Jongho and suggest to modern traditional landscapes as well as the "Noblesse oblige landscape enjoyment case."

South Korean broadcasting industry has been under a significant level of structural change since the permission of new general programming channels in the end of 2010. One of the most characteristic features of the change may be the exodus of core manpower from the in-house productions of major terrestrial broadcasters which have been maintaining their dominant power over broadcasting content market based on their systems of tight vertical integration. This paper sheds light on the presence of a purposeful 'mechanism design' that aims to the expansion of market logics in South Korean broadcasting sector by promoting commercial media conglomerates, and analyses how this external design has been actualized while being interlocked with various internal factors of the broadcasting industry. This paper shows that on the backdrop of the mechanism design, some of new media conglomerates has successfully provided various incentives in contrast with those disincentive of terrestrial broadcasters, which in turn, has facilitated the exodus of elite producers. This paper, however, raises a set of questions about whether this relocation process of creativity led by commercial media conglomerates would, in the long term, guarantee more opportunities and potentials for the producers, as promised. As part of conclusion, inherent problems of present mechanism design are highlighted.

This study aimed to develop a measure of professional identity for Korean dental hygienists and to analyze the factors and characteristics of professional identity of these dental hygienists. In this study, 890 dental hygienists completed a self-administered survey. The final analysis was conducted with a total of 880 responses, excluding 10 questionnaires with unreliable responses and partial responses. A systematic literature review was conducted to establish the definition of professional identity, while content validity, exploratory factor, confirmatory factor, and reliability analysis were conducted to establish the constructive factors. Descriptive statistics, independent sample t-test, and one-way ANOVA were used to identify the level of each factor. Authors conceptualized the professional identity for Korean dental hygienists and item generation, item reduction, and questionnaire formatting. The developed measure of professional identity for dental hygienists consisted of five factors, with 15 items. "Sense of calling," "need for academic capacity building," "performance of delegated authority," "compliance of code of ethics," and "usage of professional organizations" were the constituent factors. Based on these factors, the level of professional identity was the highest in the "performance of delegated authority" and lowest in the "usage of professional organizations." These finding indicated that dental hygienists with higher education levels have higher professional identity levels. The dental hygienists working at the general/university hospital had the highest level of professional identity. Thus, further research is needed to establish a model that consists of factors affecting and influencing the professional identity of dental hygienists.

A biodegradable polymer poly((R) -3-hydroxybutyric acid) (PHB) was conjugated with a hydrophilic polymer poly(ethylene glycol) (PEG) by the ttansesterification reaction to form the amphiphilic block copolymer. PHB with low molecular weight ($3000{\sim}30000$) was appropriated for the drug delivery materials. High molecular weight PHB was hydrolyzed by an acid-catalyst to produce the low molecular weight one. Amphiphilic block copolymer was formed the self-assembled polymeric micelle system in the aqueous solution that the hydrophillic PEG was wraped the hydrophobic PHB. Generally, polymeric micelle forms the small particle between $10{\sim}200nm$. These polymeric micelle systems have been widely used for the drug delivery systems because they were biodegradable, biocompatible, non-toxic and patient compliant. The hydroxyl group of PEG was substituted with carboxyl group which has the reactivity to the ester group of PHB. Amphiphilic block copolymer was conjugated between PHB, and modified PEG at $176^{\circ}C$ which was higher than the melting point of PHB. Transesterification reaction was verified with DSC, FTIR, $^1H-NMR$. In the aqueous solution, critical micelle concentration (CMC) of the mPEG-co-PHB copolymer measured by the fluororescence scanning spectrometer was $5{\times}10^{-5}g/L$. The shape and size of the nanoparticle was taken by dynamic light scattering and atomic force microscopy. The size of the nanoparticle was about 130 nm and the shape was spherical. Our polymeric micelle system can be used as the passive targeting drug delivery system.

The fire accident is a representative type of disaster that can largely impact on business. Therefore, precautionary measures and rapid initial response is very important when a disaster occurs. The storage of porous combustibles is inevitable in coal yard, plywood processing industry, and others that are currently operating. Initial fire fighting of fire and identifying the ignition point in such a porous combustible storage space are so difficult that if the initial response is failed, being led to deep-seated fire, surface fire is likely to result in secondary damage. In addition, deep-seated fire can cause personal injuries and property damage due to a large amount of toxic gases and reignition. Therefore damage reduction measures is required around the storage space to handle a porous flammable. Improving the penetration performance of the concentration of the surfactant is carried out as underlying study, which is about an deep-seated fire extinguishing efficiency augmentation when using wetting agents. The porous materials used in the experiments is radiata pine wood flour, which occupies more than 75% of the domestic wood market. Fire fighting water is selected as Butyl Di Glycol (BDG), which is being used for infiltration extinguishing agent, and the experiment was carried out by producing a standard solution. The experiment was carried out on the basis of the Deep-Seated Fire Test of NFPA 18. The amount of watering, porous material to the internal amount of penetration, and runoff measurement out of the porous material was conducted. According to experimental results, as the surface tension is reduced, the surfactant concentration macroscopic penetration rate decreases, but infiltration to a porous material is shown to have growth characteristics.

In the present study, the influences of the fire curtain and natural vent in a theater fire were investigated through the numerical simulation of a reduced-scale model of a theater fire using the Fire Dynamics Simulator (FDS). Based on a previous experimental study using the reduced-scale model, the 1/14 reduced-scale model and its conditions were constructed according to the law of similarity with a real-scale theater. Through a series of numerical simulations, the smoke movements were visualized, and the temperatures in the stage and auditorium, mass flow rate of the outflow through natural vent, and time at which smoke started moving toward the auditorium were measured and analyzed. The general trends on the effects of the fire curtain and natural vent during the theater fire predicted by the present numerical simulation were similar to the previous experimental results. For quantitative comparison of the present numerical simulation and previous experimental results, the mean percentage errors of temperatures in the stage and auditorium, and the mass flow rate of outflow through the natural vent were calculated. The present numerical simulation results showed good agreement with previous experimental results with reasonable accuracy.

As the importance of first responses for fire accidents has grown in the safety management of nuclear power plants, a systematic approach to measure firefighters' psychological states and competence is needed. The current study investigated the construct of the risk perception of the firefighters working near nuclear power plant sites, and then developed and validated a new scale to measure firefighters' risk perception regarding nuclear power plant accidents. The scale items were developed on the basis of literature review and interviews with the firefighters working near nuclear power plant sites. In order to validate the new scale, we recruited 180 firefighters from five fire stations in the vicinity of the nuclear power plants in Jeonnam Province, Gyeongbuk Province, and Busan. The results of exploratory factor analyses revealed that the scale consisted of five factors: "manual" reflecting a lack of response guidelines and manuals for fire incidents and radioactive material release; "fear" reflecting a fear of fire incidents in the nuclear power plants and their catastrophic consequences; "resource" reflecting a lack of protective equipment and manpower for responding to fire incidents in the nuclear power plants; "trust" reflecting trust and cooperation with the counterpart institutions for firefighting in the nuclear power plants; and "knowledge" reflecting the knowledge of radioactivity and firefighting in the nuclear power plants. Further analyses provided statistical evidence supporting for the 15-item scale's internal consistency and construct validity. Finally, We discussed the implication and limitations of the current research.
