Currently, 54 kinds of digital maps are provided by National Geographic Information Clearinghouse and the majority of those maps are based on aerial photographs or satellite image. The digital maps which symbolize and simplifies the topography and objects from ortho-photos does not reflect the objects 'shapes and facilities' changes. Especially, underground structures and complex building shapes are not correctly identifies by ortho-photos. Furthermore, the 1/1,000 and 1/500-1/2,500 maps for urban area produced by some local government or public organizations have detailed information with high precision, it is not easy to update the information due to the frequent changes of structures in the city. Although some efforts to solve this problem such as conducting field survey and shorten the survey period were tried, it is not the fundamental solution due to the high cost. Therefore, in this study, a realtime renewal and update of digital map using general survey are suggested. By assigning absolute coordinates to the general survey products and matching with digital maps, it is possible to update the digital map economically and rapidly. In addition, it is suggested that the construction of DB for general survey and sharing among survey companies to solve the duplicated survey.

The purpose of this study is to provide the ideal forecasting model of cadastral survey work load through the Economeatric Analysis of Time Series, Granger Causality and VAR Model Analysis, it suggested the forecasting reference materials for the total amount of cadastral survey general work load. The main result is that the derive of the environment variables which affect cadastral survey general work load and the outcome of VAR(vector auto regression) analysis materials(impulse response function and forecast error variance decomposition analysis materials), which explain the change of general work load depending on altering the environment variables. And also, For confirming the stability of time series data, we took a unit root test, ADF(Augmented Dickey-Fuller) analysis and the time series model analysis derives the best cadastral forecasting model regarding on general cadastral survey work load. And also, it showed up the various standards that are applied the statistical method of econometric analysis so it enhanced the prior aggregate system of cadastral survey work load forecasting.

The purpose of this study is to investigate the current status of claim management process of general contractors in South Korea. As the claim management becomes more important nowadays, maintaining the process for claim management systematically and consistently becomes more important as well. To improve the claim management process, it is necessary to diagnose the current status of claim management process so companies establish their targets for improvement. This study develops a survey to identify the current status of claim management process that major general contractors in South Korea have. Questions in the survey are classified into four categories including entitlement check, potential claim event check, time bar check, and tasks for substantiation. By conducting a series of statistical analyses with 94 survey data collected from employees working in the general contractor companies in South Korea, this study examines and analyzes their claim management process in terms of the several categories. It is expected that the results contribute to diagnosing how practitioners maintain their claim management, which will help them establish the direction of management enhancement.

Purpose: This study investigated the relationship between allergic diseases, general anxiety disorder, and depressive symptoms among Korean adolescents. Methods: A secondary analysis was conducted on the findings of the 18th Korea Youth Risk Behavior Survey (2022). The study included 51,850 adolescents and analyzed the relationships among allergic diseases, general anxiety disorder, and depressive symptoms using complex samples logistic regression analysis. Results: Among the Korean adolescents, 12.7% experienced general anxiety disorder, while 28.7% experienced depressive symptoms. The prevalence of allergic diseases was 5.7% for asthma, 36.3% for allergic rhinitis, and 22.2% for atopic dermatitis. General anxiety disorder was associated with asthma and allergic rhinitis but not atopic dermatitis. Depressive symptoms were associated asthma, allergic rhinitis, and atopic dermatitis. Conclusion: Examining the correlation among allergic diseases, general anxiety disorder, and depressive symptoms in adolescents underscores the need for implementing suitable strategies. Moreover, when addressing general anxiety disorder and depressive symptoms in adolescents, it becomes crucial to consider the presence of allergic diseases.

A general hospitals change continuously and rapidly, the way of growth and change becomes an important factor in the interior design. For this purpose, it compares and analyzes the image between different general hospital's ultrasonography with content level in the interior design to aspect investigating the preferences of the patient. Also the field survey on the real users was carried out, asking what kind of interior design you like in the general hospital ultrasonography. These research materials can be utilized for the practice application in the interior design of general hospital ultrasonography with the analyzing each available space. In the survey result, the point on the users needs things which are considered as the most important aspect for the fundamental data for the reasonable design planning and the basic principles of the modeling plan in the hospital's ultrasonography. So this study is to investigate and analyze the characteristics of the waiting area, way finding, color, lighting, counter design. This study would apply to interior design for the modeling of general hospital's ultrasonography.

Background: Dental treatment under outpatient general anesthesia is an option for disabled person, children and dentally disabled person who have the difficulty of cooperating voluntary with dental care. The aim of this study was to access the patients who had dental management under general anesthesia at Chungnam dental clinic for the disabled. Methods: This survey is consisted of 114 severely disabled and dentally disabled person who undergone dental treatment under general anesthesia from January to June 2011. Data were collected by individual dental and anesthesia records. Results: Of the 114 patients studies, the 45 patients was the dentally disabled and the 69 patients was the severely disabled. Rate of dental treatment among male patients was higher than among female patients. The dentally disabled was an similar age distribution. In the severly disabled, above 13-year-old was higher than below 12-year-old. The most popular induction method of general anesthesia was sevoflurane inhalation after induced sedative effect of nitrous oxide inhalation. The severly disabled who had definitely negative behavior was applied inhalation of high concentration sevoflurane.

Purpose: The present international survey among healthcare providers aimed to collect data on theoretical knowledge and clinical practices in the diagnosis and management of cow's milk protein allergy (CMPA) and lactose intolerance (LI) in infants. Methods: A global survey was conducted in several countries with diverse health care settings. The survey consisted of multiple-choice questions in 3 main domains: (1) understanding and clinical practices around CMPA and LI; (2) case scenarios; and (3) disease-specific knowledge and potential educational needs. Results: Responses were available from 1,663 participants. About 62% of respondents were general practitioners or general pediatricians, and the remainder were pediatric allergists/gastroenterologists (18%) or other health practitioners (20%). The survey identified knowledge gaps regarding the types of CMPA (IgE-mediated vs. non-IgE-mediated) and the clinical overlap with LI. The survey suggested diverse clinical practices regarding the use of hypoallergenic formulas, as well as misconceptions about the prebiotic benefits of lactose in extensively hydrolyzed formulas in non-breastfed infants with CMPA. Responses to the two case scenarios highlighted varying levels of awareness of the relevant clinical practice guidelines. While respondents generally felt confident in managing infants with CMPA and LI, about 80% expressed an interest for further training in this area. Conclusion: The current survey identified some knowledge gaps and regional differences in the management of infants with CMPA or LI. Local educational activities among general and pediatric healthcare providers may increase the awareness of clinical practice guidelines for the diagnosis and treatment of both conditions and help improve clinical outcomes.
