  • Background: The incidence of mycoplasmal pneumonia is predominantly at childhood and early adulthood, but in adults, its incidence is low and its symptoms and physical findings are nonspecific. The definite diagnosis of M. pneumoniae pneumonia can be made by sputum culture, but requires several weeks for positive results, and the early diagnosis must initially be based on the serologic tests and appropriate clinical findings. Thus, we evaluated the clinical aspects of M. pneumoniae pneumonia in the adults patients. Method: Among the admitted patients due to pneumonia, the definite diagnosis is anti-M. pneumoniae antibody titer of $\geq$ 1:40 and a single cold agglutinin titer of $\geq$ 1:64. The presumptive diagnosis is anti-M. pneumoniae antibody titer of $\geq$ 1:40 or a single cold agglutinin titer of $\geq$ 1:64 and the clinical characteristics or chest X-ray findings are compatible with M. pneumoniae pneumonia. We studied the age and sex distribution, seasonal distribution, clinical symptoms, physical findings, serologic test, chest X-ray findings, treatment and its progression. Results: 1) The age distribution was even and the ratio of male to female was 1:1. 2) The monthly distribution was most common in January(16.7%) and the seasonal distribution in autumn and winter(autumn: 30%, winter: 33.3%). 3) The cold agglutinin titers were higher than 1:64 in 12 cases(40%), and reached the peak level around 2 weeks from onset and antimycoplasma antibody titers were higher than 1:160 in 5 cases(16.7%). 4) On the chest X-ray, pulmonary infiltration was noted in 28 cases(93.3%) among 30 cases and right lower lobe involvement was the most common(33.3%) and both lower lobe involvement was noted in 7 cases(23.3%). 5) The mean treatment duration was most common(33.3%) in 1 week to 2 weeks after admission and 26 cases(86.7%) were improved within 4 weeks. 6) On admission, there was fever(${\geq}38.9^{\circ}C$) in 17 cases(56.7%), and the fever subsided in 12 cases(70%) within 3 days after treatment using erythromycin. Conclusion: The mycoplasmal pneumonia in adults shows milder clinical patterns than that in childhood and can be completely recovered without complication by early diagnosis and treatment.

  • The growth of a city requires substantial resources, an appropriate environment, and the alignment of several factors. City growth also evolves through changes in its history, culture, economics, societies, groups, and government systems. However, current port city development plans designed to encourage the growth of local businesses fail to provide the support needed for both the city and businesses. The recent actions of urban administrations and federal and local governments have revealed that they have yet to create a mature decentralized management system, or perhaps have ignored the reality of needing one. Taking a clear look at the differences between port regions, such as Gwangyang and Pyeongtaek, and understanding their effect on city growth would be a prudent course of action when preparing for future developments. The purpose of this study is to determine the relationship between ports and cities by analyzing the effect of port characteristics on nearby city growth. This study used a comparison analysis to determine how port characteristics affected the growth of Pyeongtaek and Gwangyang. One result of this analysis showed that an increase in the number of goods being imported or exported had a positive effect on the growth of both port cities, In this respect, an aggressive plan and cooperation between the federal and local government should occur simultaneously. Furthermore, efficient local policies that focus on the increase of personnel and material resources should be pursued as a standard strategy, which would also promote the international status of these locations. The results of this study show the importance of government cooperation. The federal government should lead with aggressive strategies that aim to optimize efficiency, while the local government should provide the necessary assistance and coordination in order to achieve optimal results.

  • This study is to provide basic information regarding photoneutron doses in terms of radiation treatment techniques and the number of portals in intensity-modulated radiation therapy (IMRT) by measuring the photoneutron doses. Subjects of experiment were 10 patients who were diagnosed with prostate cancer and have received radiation treatment for 5 months from September 2013 to January 2014 in the department of radiation oncology in S hospital located in Seoul. Thus, radiation treatment plans were created for 3-Dimensional Conformal Radiotherapy (3D-CRT), Volumetric-Modulated Arc Radiotherapy (VMAT), IMRT 5, 7, and 9 portals. The average difference of photoneutron dose was compared through descriptive statistics and variance analysis, and analyzed influence factors through correlation analysis and regression analysis. In summarized results, 3D-CRT showed the lowest average photoneutron dose, while IMRT caused the highest dose with statistically significance (p <.01). The photoneutron dose by number of portals of IMRT was $4.37{\pm}1.08mSv$ in average and statistically showed very significant difference among the number of portals (p <.01). Number of portals and photoneutron dose are shown that the correlation coefficient is 0.570, highly statistically significant positive correlation (p <.01). As a result of the linear regression analysis of number of portals and photoneutron dose, it showed that photoneutron dose significantly increased by 0.373 times in average as the number of portals increased by 1 stage. In conclusion, this study can be expected to be used as a quantitative basic data to select an appropriate IMRT plans regarding photoneutron dose in radiation treatment for prostate cancer.

  • Purpose: To identify trends in causative bacterial organisms for neonatal sepsis and antimicrobial susceptibilities over 10 years in one neonatal intensive care unit. Methods: We retrospectively reviewed the cases of culture-proven neonatal sepsis between January 1998 and December 2007. The 10-year period was divided into two phases (phase I, 1998-2002; phase II, 2003-2007) to distinguish the differences during the entire period. Results: Total 350 episodes of neonatal sepsis were identified in 315 neonates. The common pathogens of early-onset sepsis were S. epidermidis, S. aureus, P. aeruginosa, and E. cloacae in phase I, and S. epidermidis and E. cloacae in phase II. In cases of late-onset sepsis, coagulase negative Staphylococcus, S. aureus, and K. pneumoniae were isolated frequently in both phases. The incidence of sepsis caused by multi-drug resistant organisms decreased with strict infection control. Gram positive organisms showed 0-20% susceptibility to penicillin, ampicillin, and cefotaxime in both phases. Sensitivity to amikacin for Enterobacter spp. increased, whereas P. aeruginosa showed decreased sensitivity in phase II. Between 50% and 60% of other gram negative bacteria, except P. aeruginosa, were susceptible to cefotaxime in phase II in contrast to phase I. Greater than 80% of gram negative bacteria were sensitive to imipenem except P. aeruginosa and ciprofloxacin in both phases. Conclusion: The trend in causative microorganisms and antimicrobial susceptibilities can be used as a guideline for selection of appropriate antibiotics. A particular attention should be paid to infection control, especially to reduce sepsis caused by multi-drug resistant organisms.

  • The dictionary defines the word 'Design' as planning and designing. Though this is a meaning confined to decorative function, the conception of modern design in this capitalist society of mass production and mass consumption can be said to have reached a new stage of the meeting of industry and the arts. This means the two sides of design' the side of beauty and usefulness The side of beauty should be understood in view of the sense of beauty, and usefulness should also be considered from the viewpoint of consumer's taste and preference This is thought to be the natural problems of design The origin of design can be understood from the background of capitalism. But the capitalism can be said to be the mode of Western thought and action developed based on Western thinking. The capitalism is an economic system derived from the society of industrial capitalism through commercial capitalism. but this economic thinking has been resulted from a mature social system of democracy and civic society. The civic society and democracy are derived from polis of ancient Greece and Rome. and the ancient Greek and Roman society was a society developed from the social system of the nobility and slaves. Polis continued to develop based on the positive territorial expansionism centering around the Mediterranean on the basis of Hellenism. and European countries achieved the intergration of religion. society and politics based on this. thus accomplishing the spirit of capitalism Our design is believed to have been derived from the direct import of Western capitalism. Accordingly. as the original form of Western capitalism has become our economic system. so our design copied that of th West. And our traditional culture and sensitivity which are different in the original form and root of racial disposition seem to breed discord between them. It is. therefore. very important and meaningful for us to exert all possible efforts to seek the root of our disposition and tradition and grope for the appropriate thought and style of design.

  • This study was conducted to find out the optimum container for increasing acclimatization rate of in vitro mass propagated plantlets of Ever-bearing strawberry (Fragaria ${\times}$ ananassa Duch.) via bioreactor. Four types of containers were used such as transparent plastic container (TPC), plug tray (PT), I-pot (IP), and black vinyl pot (BVP). Number of date maintaining soil water content above 10% was five days in TPC, three to four days in BVP, two days in PT, and one day in IP. Survival rate of plantlets was 80% in BVP, 70% in TPC, 55% in IP, and 15% in PT. In TPC, growth increment of plantlets was the greatest among all the tested containers and the lowest in IP. Numbers of runner per plant were 3.3 in BVP, 2.9 in TPC, 1.6 in PT, and 1.2 in IP. Total cost was 44,405,300 won/10 a in BVP, resulting in reducing more 6,659,400 won/10 a than IP's (51,064,700 won/10 a). Around 102,718 plants/10 a were produced by using BVP, suggesting that 30,265.1 plants/10 a more could be produced than IP (72,452.9 plants/10 a). Production cost per plant was 432.3 won in BVP, resulting in reducing 272.5 won than IP's (704.8 won). As a result, BVP was appropriate for acclimatization of in vitro plantlets through bioreactor system.

  • Paulownia species has long been recognized in Korean traditional culture and the values of the species have been researched in various focuses. However, studies on distribution and ecological characteristics of the species are still needed. This study aimed to identify distribution trends and ecological characteristics of two Paulownia species in Busan metropolitan city using the MaxEnt model. The MaxEnt model was established based on the environmental factors such as positioning information of the Paulownia species, topography, climate and degree of anthropogenic disturbance potentiality (ADP), which was collected in the on-site research. The study verified that the accuracy of the model was appropriate as the AUC value of Paulownia coreana and P. tomentosa was 0.809, respectively. In terms of the distribution trends of the two Paulownia species in the research area depending on the distribution model, they were both mainly distributed in downtown where built-up area and bare ground were densely concentrated. The potential distribution area of the two species was identified as $137.4km^2$ for P. coreana and $135.0km^2$ for P. tomentosa. The distribution probability was high in Jung-gu, Dongrae-gu, Busanjin-gu and Yeonje-gu. As a result of the analysis on contribution of the environmental factors, it was turned out that the degree of anthropogenic disturbance potentiality (ADP) contributed to distribution of P. coreana and P. tomentosa by about 50%, and the contribution of the environmental factors had a positive correlation with the degree of ADP. The elevation had a negative correlation with both the two species, which was considered because the species must compete more with native species in natural habitats as the altitude above sea level rises. The research findings demonstrated numerically that the distribution of P.coreana and P. tomentosa depended on artificial activities, and indicated the relevance with the Korean traditional landscape. These findings are expected to provide meaningful information in using, preserving and restoring Paulownia species.

  • The goal of the study is to provide basic information that can be used to come up with environmental interpretation methods that are appropriate to the conditions of urban parks. For this matter, research was conducted to find out whether the environmental interpretation that was provided to the visitors of the World Cup Park Visitor Center encouraged them to become interested in the environment and to understand how such environmental interest was related to the level of satisfaction that the visitors were experiencing from their visits to the park. At the same time, the research was designed to find out whether the park's visitors were affected differently in terms of their environmental interests and their experience depending on the two different types of environmental interpretations; Interpreter's Interpretation and Self-guiding Interpretation. Experimental result showed no statistically meaningful correlation between environmental interpretation and environmental knowledge, though the experimental group subjected to environmental interpretation was found to have higher environmental knowledge than that of the control group, which was not subjected to environmental interpretation. As for the correlation between environmental knowledge, which was acquired through environmental interpretation, and environmental interest, the group, which showed big changes in terms of the volume of environmental knowledge, was found to have higher environmental interest than that of the group, which recorded a low level of changes in the volume of environmental knowledge. Also, the difference in their level of environmental interest was big enough to be acknowledged statistically. Also environmental interest, which was created thanks to environmental interpretation, was found to affect the level of satisfaction visitors feel when visiting the park. Even though the study was intended to find out how environmental interpretation affects park visitors by means of analysis that can be proved based on facts, it was difficult to control some of the variables due to the circumstances under which the experiments were conducted. Despite this, the study can be considered meaningful in the fact that the researches and experiments were conducted at a park that is actually visited by people. It is also believed that as one of the first studies done on the World Cup Park, it could serve as a basis upon which future studies could be carried out.

  • In the Ancient Mesopotamia, Egypt, Judas, Greece, and Rome, Phoenix dactylifera was planted in gardens or orchards to signify life, blessing, and victory. Branches of Phoenix dactylifera, likened to high and precious, were referred to one of the gifts to the king in the second century BC and have been used in the Feast of Tabernacles. And they were engraved on the walls of the temple and along with cherub. Besides, Phoenix dactylifera is compared with a righteous person in the Bible since it grows straight despite strong winds. And, it was used as a symbol of honesty, justice, and right. Churches call the week before Easter Palm Sunday since the crowd laid the leaves of date palm trees on the road and shouted "Hosanna" while waving the date palm branches when Jesus entered Jerusalem. Moreover, pilgrim in the Middle Ages was called 'Palmer' in English due to custom of returning with the leaves and branches of date palm trees as a memorial of the Holy Land pilgrimage. This study analyzes naming issue of Phoenix dactylifera through the old literature and 27 versions of the most influential Bibles in History of Bible Translation in Korea, China, and Japan. Phoenix dactylifera is translated into Chinese as '棕櫚(Trachycarpus fortunei)', a native tree of China. 棕櫚 is similar to Phoenix dactylifera, but its fruit and leaf are quite distinct. This being so, translating Phoenix dactylifera as 棕櫚 has a limit to convey symbolic meaning adequately. In the Japanese Bible, on the other hand, Phoenix dactylifera is translated as 'なつめやし(Natsumeyashi)' meant date palm tree. Most of Protestant Bible in Korea use 'Jongryeo' like Chinese Bible while translation in Korean Catholic Bible(2005) varies from one scripture to another: 'Yaja Namu (Palm Tree)' - 38 times, 'Jongryeo Namu' - 5 times, and 'Daechu Yaja Namu (Date Palm Tree)' - 3 times. Date Palm Tree, 'Jongryeo Tree', and Palm Tree don't grow in Korea. However, they had long been recognized as Haejo(海棗), Jongryeo(?櫚), and Yaja(椰子) respectively through China and Japan. Each of them called by a distinct name correspond with its own characteristic and used separately in Korean Classics as Jongryeo and Haejo were identified in ancient Chinese literatures. It seems that more confusion was raised since 'Palm' was translated as 'Jongryeo' in several books including "?藤和英大辭典 (1915)", "Modern 朝鮮外來語辭典(1938)", and "Latin-Korean Dictionary(1995)". However, the Latin term 'Palmae' is translated into English as either palm tree or date palm. The results of this study suggest that more accurate translation of Phoenix dactylifera in the Bible would be 'Daechu Yaja Namu (Date Palm Tree)' and using different name fit for its own characteristic would be more appropriate.

  • Recently, due to the introduction of high-tech equipment in interactive exhibits, many people's attention has been concentrated on Interactive exhibits that can double the exhibition effect through the interaction with the audience. In addition, it is also possible to measure a variety of audience reaction in the interactive exhibition. Among various audience reactions, this research uses the change of the facial features that can be collected in an interactive exhibition space. This research develops an artificial neural network-based prediction model to predict the response of the audience by measuring the change of the facial features when the audience is given stimulation from the non-excited state. To present the emotion state of the audience, this research uses a Valence-Arousal model. So, this research suggests an overall framework composed of the following six steps. The first step is a step of collecting data for modeling. The data was collected from people participated in the 2012 Seoul DMC Culture Open, and the collected data was used for the experiments. The second step extracts 64 facial features from the collected data and compensates the facial feature values. The third step generates independent and dependent variables of an artificial neural network model. The fourth step extracts the independent variable that affects the dependent variable using the statistical technique. The fifth step builds an artificial neural network model and performs a learning process using train set and test set. Finally the last sixth step is to validate the prediction performance of artificial neural network model using the validation data set. The proposed model is compared with statistical predictive model to see whether it had better performance or not. As a result, although the data set in this experiment had much noise, the proposed model showed better results when the model was compared with multiple regression analysis model. If the prediction model of audience reaction was used in the real exhibition, it will be able to provide countermeasures and services appropriate to the audience's reaction viewing the exhibits. Specifically, if the arousal of audience about Exhibits is low, Action to increase arousal of the audience will be taken. For instance, we recommend the audience another preferred contents or using a light or sound to focus on these exhibits. In other words, when planning future exhibitions, planning the exhibition to satisfy various audience preferences would be possible. And it is expected to foster a personalized environment to concentrate on the exhibits. But, the proposed model in this research still shows the low prediction accuracy. The cause is in some parts as follows : First, the data covers diverse visitors of real exhibitions, so it was difficult to control the optimized experimental environment. So, the collected data has much noise, and it would results a lower accuracy. In further research, the data collection will be conducted in a more optimized experimental environment. The further research to increase the accuracy of the predictions of the model will be conducted. Second, using changes of facial expression only is thought to be not enough to extract audience emotions. If facial expression is combined with other responses, such as the sound, audience behavior, it would result a better result.
