Objective: To evaluate the impact of surgical simulation training using a three-dimensional (3D)-printed model of tetralogy of Fallot (TOF) on surgical skill development. Materials and Methods: A life-size congenital heart disease model was printed using a Stratasys Object500 Connex2 printer from preoperative electrocardiography-gated CT scans of a 6-month-old patient with TOF with complex pulmonary stenosis. Eleven cardiothoracic surgeons independently evaluated the suitability of four 3D-printed models using composite Tango 27, 40, 50, and 60 in terms of palpation, resistance, extensibility, gap, cut-through ability, and reusability of. Among these, Tango 27 was selected as the final model. Six attendees (two junior cardiothoracic surgery residents, two senior residents, and two clinical fellows) independently performed simulation surgeries three times each. Surgical proficiency was evaluated by an experienced cardiothoracic surgeon on a 1-10 scale for each of the 10 surgical procedures. The times required for each surgical procedure were also measured. Results: In the simulation surgeries, six surgeons required a median of 34.4 (range 32.5-43.5) and 21.4 (17.9-192.7) minutes to apply the ventricular septal defect (VSD) and right ventricular outflow tract (RVOT) patches, respectively, on their first simulation surgery. These times had significantly reduced to 17.3 (16.2-29.5) and 13.6 (10.3-30.0) minutes, respectively, in the third simulation surgery (p = 0.03 and p = 0.01, respectively). The decreases in the median patch appliance time among the six surgeons were 16.2 (range 13.6-17.7) and 8.0 (1.8-170.3) minutes for the VSD and RVOT patches, respectively. Summing the scores for the 10 procedures showed that the attendees scored an average of 28.58 ± 7.89 points on the first simulation surgery and improved their average score to 67.33 ± 15.10 on the third simulation surgery (p = 0.008). Conclusion: Inexperienced cardiothoracic surgeons improved their performance in terms of surgical proficiency and operation time during the experience of three simulation surgeries using a 3D-printed TOF model using Tango 27 composite.

Subsidiary welfare facilities in an apartment complex are one of the most important factors for consumers when they buy an apartment due to an increase of consumers' consciousness level, increase of leisure time, and increase of cultural life. This study aims to analyze layout types and characteristics of subsidiary welfare facilities at the apartment complexes in the second phase new towns, investigate the current situation and find out the improvement direction. For this purpose, this author investigated three "second phase new towns" which were designated as a new town at similar time, and selected a total of 15 apartment complexes by selecting 5 complexes in each of the three new towns. Literature survey, case visit, photo shoot, user observation survey were used as study methods. The results of the study are as follows. First, it was found that a mixed type was the most common type of plane layout types in the subsidiary welfare facilities. This type improves accessibility and equity of the residents as the facilities are appropriately placed based on the functions and the user characteristics. Second, it can be considered that a distributed type for senior citizen centers and daycare centers may give independence to specific users, but it may give a sense of alienation to the elderly. Moreover, it does not have enough community so that it is necessary to make proper supplementation. Third, there were two lay out types. The first one is that the subsidiary welfare facilities are placed with step difference and the second one is that they are placed in sunken places using the underground space. Fourth, all layout types of outdoor facilities are distributed types, and it is considered that measurements for a proper balance of accessibility and equity are required.

Korea is facing various social problems including single elderly household, increase in the number of disabled people and poverty rate and a difference in the proportion of males to females between urban areas and rural areas along with the advent of rapid aging society. Especially, the ratio of poor households in rural areas residing in housing which falls below the minimum housing level and most of them are in the dead zone of housing welfare. In addition, if it is impossible for them to move (relocate) to new housing, the house remodeling is the only measure for improving their housing welfare. However, we don't have enough prior relevant academic and practical experience, and house remodeling requires a series of process including prior planning construction and post-occupancy evaluation, but almost no fundamental research that provides relevant insight has been carried out. Therefore, the purpose of this study is to describe all field situations that occur in the whole customized house remodeling process for disabled female senior citizens living alone in a rural area. The remodeling process was classified into initial planning stage, field verification and adjustment stage and construction stage as the method to participate in the field directly, and any change in the remodeling plan and its causes at each stage were analyzed. As a result, some remodeling items were changed from the main viewpoint of participating parties before the beginning of construction and for reasons such as the deterioration level of housing site, limitation in building equipment and rearrangement of housing, etc., and the remodeling method and its details were developed. It was identified that constant change that occurred in the remodeling process resulted from 1) unique poor characteristics of existing housing and 2) physical condition of residents and their unique lifestyle characteristics that were two aspects required to be emphasized by customized remodeling.

This research is a follow-up study of the analysis of satisfaction and preference rates in bathroom design relevant to age variable. This project examines the satisfaction and preference rates relevant to the variety a family type. Mid-sized apartments most favored by the mid-class families were selected as the objects of the research so that they represent the present conditions in Korean bathroom designs most comprehensively. In order to maintain consistency in research objects, this article limited them to the top five brand-name apartments in the metropolitan area based on the brand popularity and construction capability. The method of the research was surveys; we were able to retrieve and analyze 427 copies through internet. The data were processed by SPSS PC+ windows version 15.0 program and were analyzed using the means, crosstabs statistics, One-way ANOVA. The results are as follows: 1) The most significant factor that determines the variety a family type is the existence of senior citizens in the household. 2) The preference of families with young children is mostly determined by elements related to the safety of the children. 3) The satisfaction and preference rates are closely related to family types of each household. We sincerely hope that this article will provide guidelines for customized bathroom designs based on the ages, life cycles, and socioeconomic status of the residents so that the desings will answer to the needs of each household.

The purpose of this study is to examine the change of inner roads responding to the street system and to examine the how to influence to communal space of village focused on 22 existing old settlements in downtown Cheong Ju. This study examined the types of inner roads based on advanced research. For the research on communal space, interviews with the residents living in the village were conducted to figure out the location and function of it. Also, it was analyzed comparatively with the present communal space. The results are as followings: the width of an inner road has a effect to function of an inner road when flow of an inner road has kept. The function of inner road has been kept when the width of an inner road expanded as pedestrians should be given priority to vehicular traffic. However, the function of inner roads has been changed and the community has been separated when the width of inner roads expanded for vehicular. Because the location of the communal space in the village is affected by the change of the inner road, when the inner road is maintained, the location of the communal space is also maintained, but when the inner road is changed, the location of the communal space is also changed. The communal spaces such as public wells and wash spaces have lost and they have been substituted with senior citizen centers or community centers.

Concerns about paid-facilities for the elderly with dementia from middle and upper class families have been discussed lately in Korea. Small-scale, home-like group homes for the elderly with dementia were developed in Sweden in the 1980, but they have not been effectively introduced in Korea where they remain a comparatively new concept. The group home, however, would provide a good alternative to Koreans who feel guilty when they have to leave their frail parents in large-scale facilities or hospitals instead of caring for them at home. The aim of this paper is, first, to define the care of the demented elderly who come from upper and middle class families in Korea and, secondly, to discuss the need for group homes to help care for them. A survey was done by questionnaire and was answered by 577 respondents who belonged to middle and upper class families living in Korea in December 2000. Methods of analysis were frequency, mean, and Chi-square. The results of this study were as follows: 1) the traditional notion that the eldest son should be burdened with the primary responsibility for a demented parent has weakened remarkably; 2) a small-scale long-term care facility was considered the most desirable living environment for the demented elderly; 3) the facilities families needed for professional hospitals for victims of dementia, senior citizen centers, large and small-scale long-term care facilities, day-care centers, and short-stay and service housing. The study also revealed that there was low awareness of the group home. The most preferred type of structure for group homes was a single-family detached house, and the most preferred management system was small-scale that could create home-like atmosphere. Additionally the respondents wanted group homes to consist of 6-8 residents with 2-4 persons per room. The results of this study strongly suggest that policy makers should encourage the development of smallscale group homes as an alternative form of housing for the elderly with dementia.

Presently, there is no legal regulation pertaining to the installation, maintenance, management and operation of fire-fighting facilities in single housing in Korea, relying instead on the awareness of the residents which hopefully will prevent fire. Likewise, accident prevention effort is very limiting and weak. Accordingly, this research examines current situation in which fire results, identifies root causes and studies application of regulations and develop design measures centered on the single housing that is most afflicted with fire. As part of the measure to prevent fire that afflict housing, it is necessary to classify single housing as specific target for fire fighting just like the joint housing among the types of the building structures that are classified according to the usage on the "Appendix Chart I of the Enforcement Ordinance of the Construction Law" for management purpose. Moreover, it is necessary to make the installation of fire-fighting facilities such as simple sprinkler facility for residential area, fire extinguisher, warning system and others for the sake of the senior citizens and disabled people who reside in single housing, mandatory.

Purpose: The purpose of this study is to assess the priorities of health promotion for older adults in the rural community. The study attempts to display demographic characteristics subjective health status and chronic diseases status of the older adults. Methods: We surveyed 384 senior residents in a community via face-to-face interviews in their homes, who were selected by proportional random sampling. We analysed the frequency, multiple responses and $X^2$ by SPSS 12.0K. Results: The mean of subjective health status was $54.04{\pm}21.69$ with a maximum of 100. Our study found that the high priorities in health promotion for older adults were prevention and management of hypertension and diabetes, strengthening of joint and muscles, cancer screening and physical exercise. Prevention of depression and social activities were low priorities. Strengthening of joints and muscles was a high priority among women while smoking cessation and social activities were high priorities of men. Conclusion: In conclusion, health promotion priorities of older adults differed by gender and subjective health status. Disease-related priorities received more attention than psycho-social health priorities. This study suggests comparing the priorities regionally and nationally.

Purpose: This study was conducted to investigate the effects of a cognitive behavior program on cognition, depression, and activities of daily living in elderly with Cognitive Impairment. Method: The research design was a nonequivalent control group pretest-posttest design. There were 21 subjects in the experimental group and 19 in the control group among 40 senior residents in a Hall for the elderly in the city of S. The subjects scores ranged from 15 to 23 on the MMSE-K(Korean Version of Mini-Mental State Examination) over age 65. The length of time for data collection and intervention was from Jun 26 to September 1, 2006. The cognitive behavior program consisted of 'Facing problem behavior', 'Searching for a coping skill', and 'Training in the coping skill'. It was applied to the experimental group twice a week, fifty minutes per session for six weeks. Result: Cognition(t=-4.232, p< .001) and IADL(t=-2.939, p< .01) in the experimental group were significantly higher than those of the control group. Depression in the experimental group was significantly less than the control group(t=3.870, p< .01). However, ADL in the experimental group was not significantly higher than the control group. Conclusion: These findings confirmed that a cognitive behavior program contributed to improving cognition and IADL, and to reducing depression in the elderly with Cognitive Impairment.

The objective of this paper is to examine the proportion and characteristics of non-emergent patients at emergency departments. The observational survey was conducted using a structured form used by emergency medicine specialists or senior residents on June 7-20, 2005. 1,526 patients at ten emergency centers took part in this study. The structural form contained type of insurance, route and means of emergency department (ED) visit, triage based on the Manchester Triage Scale(MTS)-modified criteria, emergency level based on the government defined rule, type of emergency centers (Regional Emergency Medical Center; REMC, Local Emergency Medical Center; LEMC, Local Emergency Agency; LEA), as well as patient's general information. Data were analyzed using SAS statistical program(V.8.2). Descriptive analysis was performed to describe the magnitude of non-emergent patients. ${\chi}^2-analysis$ and logistic regression analysis was performed to identify the nonurgent patients' characteristics. In the MTS-modified criteria, we found a 15.3% rate of non-emergent patients. This rate differed from that of non-emergent patients obtained using government's rule. In particular, there were inaccuracies in the definition of government rule on non-emergent patients, so it is necessary to apply the new government rule regarding classification of non-emergent patients. There were significant differences in the rate of non-emergent patients according to type of ED, means of ED visit, time to visit, and insurance. Non-emergent patients are more likely to visit a D-type ED(LEA having less than 20,000 patients annually), not to use ambulance, to have 'Automobile Insurance, Industrial Accident Compensation Insurance, or pay out-of-pocket'. Non-emergent patients tend to visit ED due to illness rather than injury. Further studies on the development' of triage scale and reexamination of the government's rule on emergency visits are required for future policy in this area.
