This study evaluated the feasibility of the location for PM-10 Monitoring Stations utilizing through GIS analysis. In addition, optimal sites were investigated to properly manage PM-10 which are closely related with public health. There are 11 PM-10 monitoring stations in Daegu area and the PM-10 data monitored at these stations are utilized to understand the overall status of PM-10 pollution. However, there are contrastive issues on the locations of current monitoring stations. Thus, this study prepared the map of PM-10 concentrations in Daegu area using IDW and Kriging techniques. Furthermore, average PM-10 concentrations were calculated using zonal statistical methods according to legal divisions and then, the current monitoring stations were evaluated whether their location is appropriate or not for PM-10 pollution distribution. It was found that, on the basis of yearly, seasonal and daily concentration analysis, the location of current PM-10 monitoring stations were not appropriate, particularly as they could not represent regional PM-10 pollution characteristics. In order to supplement this deficiency, seven sites(Namsandong, Namildong, Dongildong, Buksungro 1, Jongro 1, Hyangchondong and Haejeondong) commonly selected from each analytical step are suggested as additional PM-10 monitoring sites. It is further suggested that this kind of scientific evaluation for the location of PM-10 monitoring stations are needed in order to properly manage public heath in other cities as well as Daegu area.

This study was aimed at suggest a proper planning method to select a optimal forest road network in mountains forest using GIS(Geographic Information System). To examine the field applicability, the method was applied to the National Forest at Mt. Kumsan in Namhae-gun, Gyungsangnam-do. The main results from altogether six alternative road route plans were derived from these criteria obtained the alternative route plan No.2 has two layout criteria, longitudinal gradient and earth work volume, and it showed similar pattern of existing forest road network which was designed mainly ground slope and longitudinal gradient. The alternative route plan No.6 has four criteria, longitudinal gradient, earth work volume, investment effect and landscape impact. It was different for the lowest forest road density among the alternatives and the pattern of the forest road layout was radial form, which was also quite different to other alternatives. For optimal forest road network planning, GIS provide the efficient and resonable solutions for decision making to provide the support for evaluation about various alternative road networks. If detailed inventory and relevant data are provided and also clear and objective indicators for evaluations are set up, it could be applied to preliminary analysis and detail planning stage to prevent undesirable effect such the land slide and soil erosion due to inadequate planning for forest road network.

The object of this study was to analyze the speciality of Korean traditional waterscape and unique landscape formed with reflection of the phases of the time sat the area of Juhabru(宙合樓) in Changdeok Palace as a basic research to find the prototype of Taeaek pond at Changdeok Palace and restoration of the palace. Originally, Taeaek pond at Changdeok Palace was constructed in KingInjo(仁祖) period as a name of Yongji(龍池), later it called Taeaek pond after King Sukjong(肅宗). There is an island as a symbol of the immortal isle, and Chungseojeong(淸署亭), Taiksujae(澤水齋) and Buyongjeong(芙蓉亭) which were built to view the waterscape in Taeaek pond. Buildings were built asymmetrical balance around Taeaek pond because of the morphological character of tetragonal pond. Arrangement of this area has a definite form of axial structure. Yeolgokwan(閱古觀) Gaeyuwa(皆有窩), pavilions, bridges, islands, Osumoon(魚水門) and Juhabru are located on the north and south axis, and island and Osumoon play a role as a intersection and form an east of west axis. In this study, manual of construction for an island and pavilions is provided by analyzing transformational process of island and pavilions at Taeaek pond. Furthermore, kings and officials used to statically enjoy the view around Taeaek pond area, but dynamic fishing and boating activity happened in King Jungjo(正祖) period. These historical backgrounds have an influence on the spatial organization of Taeaek pond. For instance, bridge between Taeaek pond and island was destroyed with the increase of the importance of boating. Symbolic structure around Taeaek pond means 'fish changes to dragon' and 'both of king and officials become one'. Taiksujai, carving fish, Osumoon and Juhabru are provided as a related spatial factors.

Purpose: This study intends to determine how disaster prevention characteristics of important state-designated wooden cultural properties in Gyeongsangnam-do vary according to the surrounding environments and to examine disaster prevention measures for wooden cultural properties that fit their surrounding environments accordingly. Method: The designation status and characteristics of cultural properties in Gyeongsangnam-do and Gyeongsangbuk-do were identified, and the damage status of cultural properties in Gyeongsangnam-do and Gyeongsangbuk-do was reviewed based on the history of disasters. Also, the disaster prevention environments for 58 state-designated wooden cultural properties in Gyeongsangnam-do and Gyeongsangbuk-do were analyzed separately into mountainous area, rural area and urban area, topographic characteristics were drawn. Results: For cultural properties located in urban areas, it was found that security guards were arranged properly and disaster prevention training was carried out well. In addition, access condition to the cultural properties was adequate; prompt access to such properties was possible. In rural areas, flame retardant works have been undertaken properly and many cultural properties were found to be located on a flat ground. Mountainous areas had highly inadequate access condition to cultural properties and disasters occurred most frequently in these areas in the past. Conclution: First, for wooden cultural properties located in urban areas, it is necessary to secure the self-defense fire service manpower for an initial response and reinforce the disaster prevention education. Second, for wooden cultural properties located in rural areas, prevention projects such as insect control project and disaster prevention insurance should be carried out in order to protect the cultural properties. Third, as for wooden cultural properties located in mountainous areas, it is necessary to prepare establish to reinforce self-response capability.

This study presented the criteria for analyzing the corrosion of the powder extinguisher storage container according to the useful life, and conducted an experiment on the market area, the factory area, and the apartment building area to ensure proper performance at all times and drew the following conclusions.First, the experimental value for the degree of corrosion of external contact storage containers was found to be unsuitable in the factory area in 2014. In 2012, the experimental value for the degree of corrosion of external contact storage containers in apartment complexes was found to be inappropriate. Second, the experimental value for the dropout of the external paint in the storage container was found to be inappropriate in the factory area in 2014. In 2012, the experimental value of the degree of coating of the external paint storage container in the apartment building area was found to be inappropriate. It was analyzed that the useful life of the fire extinguisher is 10 years, and if it passes the sample test only once, it will be used for up to 13 years, but in fact, the difference varies greatly depending on the surrounding environment of the fire extinguisher place. Since the degree of corrosion of the storage container of the fire extinguisher from 8 years of the fire extinguisher's useful life is clearly decreased, it is judged that 5 years of the fire extinguisher is appropriate.

In order to study the effects of probiotic and antibiotic on the performance of the chickens and the population of microfloras in the intestine, a feeding trial was conducted for a period of seven weeks. One hundred eighty hatched male chickens of layer attain were fed one of the following three experimental diets; nonmedicated control, antibiotic supplemented diet(virginiamycin 5 ppm) and probiotic supplemented diet. Birds fed probiotic supplemented diets were heavier and consumed more feed than those fed other diets but the differences were not statistically significant. Antibiotic supplemented group showed significantly (P〈0.01) better feed efficiency than other groups. Availabilities of dry matter, crude protein, crude fat, NFE, Ca and P were not significantly different between treatments but antibiotic supplemented group showed significantly(P〈0.05) lower availability of crude fiber than other groups. The weight of small intestine of the birds fed antibiotic supplemented diet was significantly (P〈0.05) lighter than those of other groups. The population of Bacillus subtilis and Lactobacilli in the intestinal content of the birds fed probiotic supplemented diet were significantly (P〈0.01) larger than those of other groups. On the other hand, the population of Coliforms in the probiotic group were significantly (P〈0.01) smaller than those in the nonmedicated control group.

In order to study the effect of feeding moldy corn in the feed and to compare the efficacy of several antidotical treatments, a feeding trial was conducted using broiler chickens. Ground yet low corn was adjusted to contain 20% moisture and then incubated at 35$^{\circ}C$ for 20 days. The number of fungi increased from 11${\times}$10$^4$/g to 42 10$\^$7/g on incubation but aflatoxins (B$_1$, B$_2$, G$_1$, G$_2$) were not detected by TLC test. Moldy corn was included in the experimental diets at the level of 7% with various treatments. Thirty six hatched male broiler chickens were divided into 6 groups and each group was placed for 4 weeks on one of the following treatments: Fresh corn, Moldy corn, Ammoniated (1.5%) moldy corn, Moldy corn＋BHT (0.1%), Moldy corn CTC (100ppm) and Moldy corn＋Probiotics. Weight gains of the birds fed Ammoniated moldy corn diet, Moldy corn＋Probiotics dist and Moldy corn＋CTC diet were greater by 6.1%. 7.6% and 3.9% respectively than those fed Moldy corn diet. The feed efficiencies of Moldy corn＋Probiotics diet and Moldy corn＋CTC diet were better than those of Moldy corn diet. Dry matter contents of the livers of the birds fed Ammoniated moldy corn diet, Moldy corn＋BHT diet and Moldy corn diet were lower than those of other treatments. Proteion contents of the livers of the birds fed Moldy corn diet, Moldy corn ＋CTC diet and Moldy corn＋BHT diet were lower than those of other treatments. Moldy corn tended to increase fat content of the livers.

This study investigated the recognition of Koreanesss, preference factors and the difference of recognition from adjacent Chinese and Japanese gardens for foreign visitors of Seoul gardens, a Korean traditional garden located within the Marzahn garden in Berlin, Germany. Overall, the Chinese garden and the Japanese garden were better known to most visitors than the Seoul garden due to their earlier construction. The awareness of the specialty to the Korean garden was at an average level indicating most visitors did not recognize the difference among the traditional gardens constructed from other countries. These less awareness on the Korean garden was because the traditional gardens of the three countries are located adjacent to the park in a continuous landscape with similar plant species created through natural planting techniques. This means the Korean garden is required for considering diversity and representativeness of planting species, uniqueness in space composition and recognition of Korean oriental garden culture in an initial design project stage. Visitors without prior information has better understanding on Korean garden and higher revisit intention resulting in increasing publicity and understanding of Korean traditional garden. Among the preference factors representing Koreaness of the Seoul gardens, the waterfall, stream, pavilion and natural stone within the water landscape were visitors favorite interests due to design concept with a representative Korean stream scenery of Dokrack-dang and Byeolseo garden resulting in differences from the landscape displaying technique for other oriental gardens. These stylistic differences in the dominant landscaping of garden architecture from surrounding the physical environments, the garden displaying technique derived from Korean natural landscape can be recognized as an unique garden element for foreign visitors.

The purpose of this study is to investigate the effect of emotional labor and job stress on patient safety management activities in emergency room nurse. Data were collected using self-report questionnaires from 143 nurses working in the emergency room of small and medium-sized hospitals. As factors influencing patient safety management activities, emotional labor, job stress, demographic characteristics, and work characteristics were investigated. Stepwise multiple regression analysis were used for factors affecting patient safety management activities. There were significant differences in patient safety management activities by age, experience in emergency room, position, work pattern, and intention to move to another department. In the regression analysis, the factors that had a significant effect on patient safety management activities were job stress and choice to work in the emergency room, and the explanatory power of these variables was 27%. It was found that the higher the job stress, the lower the patient safety management activity. In conclusion, it is necessary to manage job stress arrange departments according to individual needs to improve patient safety management activities of nurses in the emergency room of small and medium-sized hospitals.

This work was carried out to assess the effect of microbial phytase (MP) on the performance, retention and excretion of phosphorus, and nutrients availability in broiler chicks. Two hundred and sixteen one day old Ross strains broiler chicks were used to investigate on performance for 5 weeks (earlier $(0{\sim}2wk)$, finisher $(3{\sim}5wk)$) and were divided 3 treatments, three cages per treatment and 12 birds per cage. Treatments are P0 (basal diet), P1 (microbial phytase 300 FTU/kg), and P2 (microbial phytase 600 FTU/kg). After 5 weeks, three diets containing 0, 300, 600 FTU/kg of microbial phytase were fed to 5-wk-old broilers to assess the digestibility. Twenty seven broilers were divided into 3 treatments (9 birds per treatment) to investigate on the absorption and retention of phosphorus and nutrient digestibility. Body weight gain and feed efficiency were highly significant at P1 and P2 treatments compared to those of P0 (P<0.05), however, feed intake was no significant difference among all treatments (P>0.05). The excretion of phosphorus decreased in P1 and P2 compared to P0 (P<0.05). The digestibility of nutrients and amino acid was high in P1 and P2 treatments compared to P0 (P<0.05). Ileal digestibility was lower about $1{\sim}2%$ than feces digestibility (P>0.05). Finally, microbial phytase influenced on the performance, the retention and excretion of phosphorus and ileal and feces digestibility in broilers.
