Purpose : To investigate the nature of deviant voice physiology in preoperative children with congenital heart disease. Methods : Ninety-four children with congenital heart disease were enrolled. Their cries and related acoustic variables (fundamental frequency, duration, noise to harmonic ratio, jitter and shimmer) were analyzed using a multi-dimensional voice program. Results : The average fundamental frequency showed a significant decrease in patent ductus arteriosus, ventricular septal defect, and tetralogy of Fallot, except in atrial septal defect and pulmonary stenosis. The length of the analyzed sample (duration) did not show a significant difference when compared with the control group. There was a significant increase in jitter percent in ventricular septal defect, patent ductus arteriosus, and atrial septal defect. There was an increase in shimmer in ventricular septal defect, patent ductus arteriosus, and atrial septal defect. The noise-to-harmonic ratio increased in ventricular septal defect, patent ductus arteriosus, and atrial septal defect but there was no significant difference in pulmonary stenosis and tetralogy of Fallot. While analyzing acoustic variables, the voice change was significantly higher, especially in patent ductus arteriosus followed by ventricular septal defect and atrial septal defect. Most of these acoustic variables were deviant in left-to-right shunt lesions in congenital heart disease, especially in patent ductus artriosus. Conclusion : The results of the voice change analysis of preoperative children with congenital heart disease revealed that the acoustic variables differed by each congenital heart disease. Moreover, the acoustic variables were prominently deviant in congenital heart disease with left-to-right shunts.

This study aims to compare and analyze somatotype characteristics in clothing ergonomics as well as Sasang (Oriental physical constitution type classification into 4 kinds: taeyang, taeeum, soyang, soeum) medicine. The subjects were women collegians in their 20s. As a result, a new approach was made in somatotype classification. The following are conclusions: 1. The results of body measurement of the subjects belonged to 1 in most items when they were compared with the average records of female adults in their 20s in the national standard physique report. Thus, the subjects belonged to the average somatotype. 2. According to Sasang physical constitution classification, no subjects belonged to taeyang-type. Taeeum type (28.4%), had lower-body development greatest height and even development in width, thickness and girth. Soeum-type(37.8%) had the smallest physique. Soyang-type(33.8%) showed small values in height but great values in width, thickness and girth. 3. The factor analysis revealed 5 factors of somatotype characteristics: lower body factors including body weight, upper body factors, height factors including stature, belly width factors including waist and belly, and other factors comprising ankle and head size. 4. A cluster analysis by way of factor scores resulted in 3 types: cluster 1 44.6%, biggest values, largest somatotypes; cluster 2 17.6%, average somatotypes; cluster 3 tiniest somatotypes in most items. 5. In the crosstabs analysis, taeeum-type (57.6%) appeared a lot in cluster 1, soyang-type (76.9%) appeared most in cluster 2, and soeum-type (69.9%) was mostly seen in cluster 3. To sum up, the somatotype analysis of clothing ergonomics had something to do with constitution classification suggested in Sasang medicine. For clear justification, more systematic and scientific research should be followed with even more diverse subjects in sex and age.

The shortage of parking lots in aged apartment complexes built from the 1980s to the mid 1990s is serious. When we look at the case of parking lot expansion in the aged apartment complexes, the method of extending the underground parking lot vertically occupies the majority. It is very important to secure the structural safety of the foundations when the existing buildings are enlarged. In the case of underground vertical work, the work space should be narrow, so that a method with excellent safety, environmental and construction properties should be applied. Urban construction is also required to use construction methods and equipment with low noise and vibration. This study analyzed the factors influencing the selection of the foundation reinforcement method for the expansion of the underground parking lot and Weights of influence factors were calculated. The purpose of this study was to analyze the applicability of the foundation reinforcement method. Factors influencing the applicability of the foundation reinforcement method were derived through expert interviews and The AHP technique was used to calculate the weight of the influencing factors. It was evaluated by experts on the applicability of the foundation reinforcement method. It conducted a case study on two types of underground parking lot expansion type and compared the applicability of the foundation reinforcement method.

After the 1980s, as the economy was growing rapidly and the real estate market was active, a large increase in population was supplied to the city. Accordingly, the national apartment housing market is located in the form of Urban Housing Culture. On the other hand, with time, the supply apartment houses became superannuated and the residential environment became poor. Therefore, the environment of old apartment houses has been changed to improve by reconstruction. Despite this, reconstruction incurred not only a lot of construction waste, but also problems of environmental degradation, noise, traffic congestion, increasing number of households, and so on. Recently, the housing law has changed, and vertical extension remodeling focused on Small/Medium Town House is underway. This has been changed in response to the demand. This is one of essential parts in the remodeling field for the future, even though it has some problems in how uses existing buildings. Therefore, this study analyzed occurrence risk factor for each type through research materials and case analysis regarding the vertical extension remodeling of apartment housing. In addition, the relative importance was determined through questionnaires and interviews from constructors, designers, and experts in the field.

OSC is a type of supply chain and value chain that spans the entire process of construction production (planning, design, construction, maintenance, etc.). It is a method of producing the final object by manufacturing it in a factory, transporting it to the site, installing and construction. This research as is the construction cost was compared for each case A, which applied the PC method, and case B, which applied the RC method. In the case of applying the PC method (excluding the PC design cost), compared to the case where only the RC method was applied, the frame construction cost per unit quantity (m³) increased by about 70% (50% based on the total RC construction type). Of the total frame construction cost of PC method application, PC accounted for 90.2%, 'PC manufacturing cost' 54.8%, 'PC assembly cost' 28.5%, and 'transportation cost' accounted for 6.89%. Also a decision-making framework that can consider both costs and benefits was established. In the case of benefits, the construction period, defect repair, disaster occurrence, energy efficiency, noise/dust/waste, and greenhouse gas emission indicators reflecting OSC technical advantages were presented. It can contribute to providing a basis for helping decision-making on the introduction of PC apartment houses using OSC.

Companion animals are increasingly being recognized as members of society in outdoor public spaces. However, the presence of dogs in cities has become a subject of conflict between pet owners and non-pet owners, causing problems in terms of hygiene and noise. This study was conducted to analyze public complaint data using the keywords 'dog,' 'pet,' and 'puppy' through text mining techniques to identify the causes of conflicts in outdoor public spaces related to dogs and to identify key issues. The main findings of the study are as follows. First, the majority of dog-related complaints were related to the use of outdoor public spaces. Second, different types of outdoor public spaces have different spatial issues. Third, there were a total of four topics of dog-related complaints: 'Requesting a dog playground', 'Raising safety issues related to animals', 'Using facilities other than dog-only areas', and 'Requesting increased park management and enforcement related to pet tickets'. This study analyzed the perceptions of citizens surrounding pets at a time when the creation and use of public spaces related to pets are expanding. In particular, it is significant in that it applied a new method of collecting public opinions by adopting complaint data that clearly presents problems and requests.

This study aimed to establish a systematic and comprehensive operational plan for the library to be constructed in the Gwacheon Knowledge Information Town. To achieve this, a survey on the demand for library operations was conducted among actual users of the Gwacheon City Public Library, and plans for the library collection development, user services, and methods to revitalize use were formulated based on the survey results. The findings are as follows. First, the library's construction/space analysis results suggest the need for a multifunctional cultural space accessible to everyone, serving as both a relaxation area and venue for a free information exchange and communication, allowing for a certain level of noise to facilitate an open atmosphere for users. Second, the analysis of the preferred types and forms of library materials revealed that printed materials ranked first, followed by web resources in the second place, and e-books/e-journals in the third. Additionally, there was a high preference for subjects such as literature and history. Third, a high preference was observed for cultural and arts programs, indicating the need for the future Gwacheon Knowledge Information Town Library to strengthen and implement programs focusing on cultural and artistic themes.

The purpose of this paper is aimed at identifying the planting condition of greenbelt axis covering forests located at Sinhyeon-eup, Geoje-si and also establishing improvement plans for the ecological organization. The study was executed with buffer green space designed to mitigate noise, which is located at a halfway point linking Mt. Yukkyo(altitude of 50m) and Mt. Jungmae(altitude of 131m). The number of the biotope patterns was classified into 17 in total: the two are urbanized districts such as a townified district and streets and another 15 are greenbelts and open space such as forest biotope, inland water biotope, and landscaping tree plantations biotope. According to the analysis of biotope types, it was estimated that the making use of already established buffer greens as a linking medium with a foothold of Mt. Yukkyo and Jungmae, whose natural eco-system is well suited for habitation of living organism, is the one and only way to the influx of living organism into the downtown area. The green coverage rate of the base green area, sub-base green area and linkage green area was 160.29%, 128.37% and 44.37% respectively; the green capacity coefficient(i.e. GVZ[$Gr{\ddot{u}}nvolumezahl$]) for base green area, sub-base green area and linkage green area was $4.04m^3/m^2,\;3.95m^3/m^2\;and\;0.65m^3/m^2$ respectively. The base green area has constituted multi-layered vegetation structure and thus played a role as habitats for living organism and supply centre of species, whereas the sub-base green area has destroyed lower layer vegetation, and the linkage green area was in bad shape due to the lack of planting volume and damage of the shrub layer. Accordingly, this research paper intended to suggest detailed implementation plans for the improvement in landscape for city dwellers' use and relaxation; in other words, this paper focused on ecological build-up for the Influx of wild birds into the downtown area for the promotion of bio-diversity of species through the linkage of base green areas and the fostering of nature observing trails for citizens as well as the connecting of green areas through the build-up of roadside greens to make these green areas to be efficiently used as corridors for the influx of wild birds and bio-organism habitation and for citizens' using space.
