As architectural forms tend to be large-scaled, high-storied and complicated, use of computer for processing design information has been generalized. However, CAD use in the process of developing architectural design has been neglected greatly in the educational field of architectural field due to the surging of recognition that it may limit the essential property of architectural design. It may be resulted from the limitation of CAD system, that is, it is because of tardy speed of application development for the related areas with the lack of simplicity and clarity of flexibility to be secured on the drawing and user interface. Recent CAD systems, however, overcome such a limitation, convert into object-based design from entity-based drawing, drafting and modeling for implementing design concept of architects and it connects with internet linked to superspeed information communication network and changes process and stream of architectural design. Therefore, this study deals with utility of object based CAD system with products of Autodesk Co. and consequently obtain the following conclusions. First, it expands architect's design areas by supporting cooperative design system based on model-based architectural design and internet. Second, it reduces consumption of personal and material resources and time in the process of drawing production for improving architectural design works. Third, it can reduce the frequent design changes by improving understanding of architectural space with visualization of immediate 3D information, escaping from traditional methods to deliver design information to building owner through 2D drawing or model and perspective drawing requiring much cost and time. Fourth, it keeps exactness without omission or duplication of design information and generate and renew information of all related drawings on a drawing. Fifth, it is possible to change difficult and boring architectural design work into a pleasure owing to immediate modeling and drawing of design idea. In addition, digital drawing generated by using object-based CAD system can playa role of establishing Urban Information System to be used for protecting from building in disaster and urban disasters in connection with GIS numerical map and be used for reference of all kinds of information required fro post-management of buildings. However, what is more important is that surplus time from introduction of object-based CAD system should be used for consideration to be recognized as a good space and building built as a product of this project for comfort to urban people.
The purposes of this work were to assess the cognition of the registered nurse(RN) on oral and maxillofacial emergency treatment and to compare cognition of the RN with that of the 119 emergency medical technician(EMT). 450 RNs who were working at each of secondary hospitals in Jeju province had responded to the questionnaire. Independent sample t-test and chi-square test were used to assess the state of RN on dental emergency treatment and to compare RN with EMT. The question 'education time on dentistry in formal education' that marked '0 hour' and '1-3 hours' were 73.3% and 20.0%, respectively. The question 'refresher training class on dentistry' that marked '0 hour' and '1-3 hours' were 92.9% and 6.7%, aggregately 99.6%. The results showed low score in the question 'reduction of temporo-mandibular joint(TMJ)'($1.67{\pm}0.857$), 'fixation of dislocated TMJ'($1.70{\pm}0.853$) and 'post-avulsed tooth treatment'($1.78{\pm}0.774$) by 5-point Likert scale. Likewise, the scores were $2.02{\pm}0.806$ in the question 'treatment of maxillofacial trauma', $2.76{\pm}1.061$ in the question 'emergent care of avulsed tooth', $2.70{\pm}1.095$ in the question 'treatment time of avulsed tooth' and $2.79{\pm}1.056$ in the question 'mouth guard', respectively. Compared to EMT, results of RN showed a statistically lower figure(p<0.05) in all items compared except the question 'medicine control', and the question 'doctor care in emergency room' was borderline(p=0.069). From this study, it is necessary for RN and student of nursing science to be educated on the oral and maxillofacial emergency treatment for the initial management of injuries. Authors suggest further co-study and nation-wide research with nursing care.

Purpose: The purpose of the study was to develop an emotional self-regulation program for obese children and to examine the program's effectiveness on depression, eating habits, and body mass index. Methods: The emotional self-regulation program was developed from theory-based strategies and a pre-post pilot study was conducted with 46 children (19: intervention, 27: control). The program included 6 weekly group sessions over 2 months. The embedded experimental model of concurrent mixed methods was used to better understand research outcomes by converging both quantitative and qualitative data. Anthropometric measurements and surveys were performed before and after the intervention. Three focus group interviews were conducted with all participants after intervention to explore their experiences. Results: The intervention group displayed decreased depression levels in the quantitative outcomes. The participants also expressed positive outcomes such as improvements in confidence, impulse management, intimacy, happiness, and losing weight. Conclusion: These findings suggest that emotional self-regulation skills are crucial factors for obese children not only to manage their emotional problems but also to control their weight. Further research is needed with a larger sample size and randomized controlled trials.
As a result of technical advances and industrialization, the characteristics of domestic and industrial wastes are becoming more complex. Accordingly, improved treatment and disposal systems are being continuously sought to take account of complex characteristics and to comply with economic restrictions. In this study, an application of pyrolysis to the treatment of industrial wastes, including waste scrap rubber, waste raw material used in making the slipper bottom and waste PVC pipe, and the effectiveness of pyrolysis in resource recovery from these wastes were investigated. Batches of wastes were pyrolysed by external heating to a temperature of 400-800$\circ$C in a 32 mm diameter x 0.9 m long silica tube to produce combustible gases, oils and chars. Before the start of pyrolysis runs, the entire system was purged with nitrogen gas to exclude the air. The temperature inside the retort was controlled by the thermocouple in the gas stream, and referred to as the pyrolysis temperature. Under these conditions three products were separately collected and further analyzed. The results were summarized as follows. 1. More gases and less chars were produced with higher pyrolyzing temperature and with higher rates of heating, but the yields of oils tended downwards at temperatures above 700$\circ$C. Accordingly, operating conditions of pyrolysis should be varied with desired material. 2. Calorific values and sulfur contents of produced oils were sufficient and suitable for fuel use. Chars from waste rubber had high heating values with low sulfur contents, but calorific values of chars from waste PVC and waste slipper were as low as 3, 065-4, 273 kcal/kg and 942-2, 545 kcal/kg, respectively. Therefore, char from these wastes are inappropriate for fuel. 3. Soluble contents of Pb, Cd, Cu and Zn in chars from waste rubber and waste slipper were below the Specific Hazardous Waste Treatment Standards. However soluble contents of Pb and Cd in chars from waste PVC were one or two times and five or seven times exceedingly the Specific Hazardous Waste Treatment Standards, respectively. 4. Post high heating is desirable for treatment method of waste PVC which generates toxic hydrogen chloride. 5. The proportions of hydrogen, methane and ethane in produced gases were in the range of 3.99-35.61% V/V, 18.22-32.50% V/V and 5.17-5.87% V/V, respectively. 6. Pyrolysis is a useful disposal method in case of waste slipper, which was hardly combustible, and thus investigations of this kind of materials are required for effective management of industrial waste. 7. Based upon the possible market development for products, overall pyroly economics to take account of treatment values of noncombustible or hazardous materials should be evaluated.
This study was aimed to analyze the variables measuring stress and immune responses, to identify the relationship between stress and immune responses, and to find out the effect of nursing interventions associated with stress and immune responses by reviewing thirty-four published articles since 1970 in Korea. The articles were selected in the field of nursing, stress management, and masters or doctoral dissertations and limited to human subject. Among these, the thirty-one articles were published since 1996 and mainly distributed in nursing (44.1%) and medicine(44.1%). The prevailing research design was nonequivalent control pre-post experimental design(41.1%). The research subjects were 55.9% for patients and 44.1% for healthy general persons including 20.6% of university students. To evaluate stress, both physiologic and psychosocial measures were adapted together in 35.3% of the articles. The most frequent two variables measuring stress and immune response were cortisol level(15.9%) and number or activity of natural killer cell(25.9%). The relation between stress and immune responses was positive in 4 articles, negative in 9 cases, and none in 12 cases. Decreased stress and enhanced immune function have been found when massage, abdominal breathing, exercise, relaxation, and touch were provided as nursing interventions. The articles to investigate the relationship between stress and immune function were limited and the tested variables were diverse. Also there was no consistent evidence to correlate the stress and immune function at present. Further studies are needed to construct a valid research design and to investigate the relationship between stress and immune responses. Nursing interventions to decrease stress should be developed to result in the increased immune function and the effect of these interventions would be verified.

Among the fintech businesses that are actively developing around the world, payment and settlement are the most prominent. Korea has a well-developed IT industry and a good existing card payment environment, however, its innovative movement is overwhelmingly slower than that of other countries in the fintech. In this study, we try to assess the regulations on fintech and their impacts on the startup ecosystem by comparing the cases of U.S., China, and Korea. We have found that both the United States and China have lowered barriers to entry for the newly launched fintech industry, allowing startups and IT companies to start fintech businesses at the existing financial sector. Particularly the implementation of predictable regulations in U.S., and the failure to apply the financial regulations in China, help start-up companies' growth in the fintech industry. This finding provides us with a lesson that current positive regulations in Korea should gradually change into negative regulations, and predictable regulations that strictly enforce post-management except major items rather than pre-approval. The policy implications are discussed with the perspective of start-ups in fintech industry.
We discovered various sides of Lee Jema's tenure as the governor of Jinhae by looking at recently found historical materials of the central government of Joseon. Lee Jema went to his appointed post in Jinhae in February of 1887 and was replaced before the termination of his office in June of 1888. Since his replacement did not immediately arrive at Jinhae, Lee Jema continued to perform his duties until the first half of 1889. The difference between the date of his resignation and the arrival of his replacement reveals why various historical materials disagree about when he left office. After Lee Jema's official resignation in June of 1888, he was appointed to the honorary posts of Naegeumjang and Cheomji, which indicates the termination of his career as an official. Two superior officials conducted job assessments on Lee Jema three times during his service (once every six months) and these are the rare evaluations which were performed during his lifetime. Lee Jema was highly regarded in terms of job competency by two superiors in succession, which was unique for a local government official in the late Joseon dynasty. One of the job assessments referred to the potential of his performance as an official which usually implied that he was a suitable candidate for higher rank. This might have derived from Lee Jema's study of statecraft. Lee Jema's love for the people as an official was also mentioned in one of the job assessment reports. This is borne out by his quelling the revolt of Hamheung Province in 1896.

Recently, there are many studies related aerial mapping project and 3 dimensional shape and model reconstruction using UAV(unmanned aerial vehicle) system and images. In this study, we create 3D reconstruction point data using image matching technology of the UAV overlap images, detect shape change of structure and perform accuracy assessment of area($m^2$) and volume($m^3$) value. First, we build the test structure model data and capturing its images of shape change Before and After. Second, for post-processing the Before dataset is convert the form of raster format image to ensure the compare with all 3D point clouds of the After dataset. The result shows high accuracy in the shape change of more than 30 centimeters, but less is still it becomes difficult to apply because of image matching technology has its own limits. But proposed methodology seems very useful to detect illegal any structures and the quantitative analysis of the structure's a certain amount of damage and management.
A study was conducted to examine the effect of precooling (2, 4, or $8^{\circ}C$) and storage (4, 8, or $10^{\circ}C$) temperatures on the storage life of 'Maehyang' and 'Soogyeong' strawberries for export. Fruits at a 70% ripe stage were harvested from a commercial greenhouse in Jinju on March 16, 2010. Fruits were precooled by a forced draft cooling for 3 hours, transported for about 30 minutes to a lab., and then stored. For precooling, small precoolers set in the farm were used. During storage, fruits were examined for their changes in weight, hardness, color (hunter value), soluble solid content, incidence of gray mold (Botrytis cinerea), and marketability at a two days interval from March 16 to March 30. In both cultivars, hardness, sugar content, and hunter value were higher in 'Soogyeong' than 'Maehyang'. The greatest hardness and soluble solid content were obtained after storage at $4^{\circ}C$ in both cultivars. As the ripening stage progressed, hardness and soluble solid content decreased. Also, fresh weight decreased during storage at all temperatures. Gray mold was the greatest at $10^{\circ}C$ storage temperature. The results indicate that effectiveness for keeping the freshness was best achieved by precooling at $2^{\circ}C$ and storage at $4^{\circ}C$ in both cultivars.

There is a need to develop diverse cultivation species with reference to the favorites and farming experiences of allotment garden participants, in addition to the crops being cultivated in the gardens. In this study, therefore, a survey on the status of cultivation and the demand for herb crops for the garden participants was conducted. Current trend of the programmes related to allotment garden for city dwellers, executed by various relevant organizations was analyzed. A questionnaire was accomplished by adult participants experiencing farming in allotments. Likewise, interview with farm proprietors was conducted. The results showed that the number of crop species cultivated in allotments was about ten species. The purchase of seeds and nursery plants was mainly dependent on the farmland proprietors. The selection of the crops was made by both wife and husband. The status of herb utilization indicated that 5.7% of participants were cultivating or had cultivated herb plants. Sixty-two percent of participants were not cultivating herb plants because they did not know how. The purposes of using herbs were for medicine and beauty (22.0%), for spices (22.0%) and for enjoyment (29.0%). Thirty-four percent (34.0%) of participants were interested or would like to use the herbs in the future for medicine and beauty, 39.0% for spices and 31.7% for enjoyment. It is expected that the demand for herbs would increase. Also, 78.3% of participants had the intension or had taken into consideration to cultivate the herb plants, if the farmland proprietors would provide the plants. And, they had interest in planting, management and post harvest utilization and if a reference material would be provided as well. An approach to plant new crops might be possible to those who have more than four years of farming experience and possess relatively high level of cultivation techniques. In conclusion, the favorable crop cultivation strategy corresponding to the participants' abilities; and rental process were essential for the sustainable operation of allotment gardens and expanded number of participants. Moreover, there is a need to pay attention to the city dwellers who have a lot of farming experiences in allotment gardens to maintain agriculture and rural community. This is so, because they are interested in agriculture and rural community and most of them replied that they had intentions to move to rural areas in the future.
