This study conducted surveys of 88 eldery people over 100 years in Gyeongnam on April to June, 2011 during 90 days. It was intended to find the factors of longevity, Activity Daily of Living (ADL), and Instrumental Activity Daily of Living (IADL). Major results of this study were as follows: The factors of longevity are getting enough sleep over than seven hours(95.5%), taking in less salty food (69.8%), optimism without even thinking about suicide (86.9%), nonsmoking habit (92%), and moderation in drink (86.4%). The most difficult part of Activity Daily of Living (ADL) is taking a bath, and that of Instrumental Activity Daily of Living (IADL) is taking a bus or subway alone. All items of ADL and IADL, female was higher than the male, but not statistically significant(p<0.05). Therefore, further study is expected to develop the supplementary policy to support the elderly people with declining to carry out physical activities. It is also expected to develop the public welfare programs and policies for the aged, allowing them to take responsibility and to participate as a member of the society.

Early detection of schedule delay in field construction activities is vital to project management. It provides the opportunity to initiate remedial actions and increases the chance of controlling such overruns or minimizing their impacts. This entails project managers to design, implement, and maintain a systematic approach for progress monitoring to promptly identify, process and communicate discrepancies between actual and as-planned performances as early as possible. Despite importance, systematic implementation of progress monitoring is challenging: (1) Current progress monitoring is time-consuming as it needs extensive as-planned and as-built data collection; (2) The excessive amount of work required to be performed may cause human-errors and reduce the quality of manually collected data and since only an approximate visual inspection is usually performed, makes the collected data subjective; (3) Existing methods of progress monitoring are also non-systematic and may also create a time-lag between the time progress is reported and the time progress is actually accomplished; (4) Progress reports are visually complex, and do not reflect spatial aspects of construction; and (5) Current reporting methods increase the time required to describe and explain progress in coordination meetings and in turn could delay the decision making process. In summary, with current methods, it may be not be easy to understand the progress situation clearly and quickly. To overcome such inefficiencies, this research focuses on exploring application of unsorted daily progress photograph logs - available on any construction site - as well as IFC-based 4D models for progress monitoring. Our approach is based on computing, from the images themselves, the photographer's locations and orientations, along with a sparse 3D geometric representation of the as-built scene using daily progress photographs and superimposition of the reconstructed scene over the as-planned 4D model. Within such an environment, progress photographs are registered in the virtual as-planned environment, allowing a large unstructured collection of daily construction images to be interactively explored. In addition, sparse reconstructed scenes superimposed over 4D models allow site images to be geo-registered with the as-planned components and consequently, a location-based image processing technique to be implemented and progress data to be extracted automatically. The result of progress comparison study between as-planned and as-built performances can subsequently be visualized in the D4AR - 4D Augmented Reality - environment using a traffic light metaphor. In such an environment, project participants would be able to: 1) use the 4D as-planned model as a baseline for progress monitoring, compare it to daily construction photographs and study workspace logistics; 2) interactively and remotely explore registered construction photographs in a 3D environment; 3) analyze registered images and quantify as-built progress; 4) measure discrepancies between as-planned and as-built performances; and 5) visually represent progress discrepancies through superimposition of 4D as-planned models over progress photographs, make control decisions and effectively communicate those with project participants. We present our preliminary results on two ongoing construction projects and discuss implementation, perceived benefits and future potential enhancement of this new technology in construction, in all fronts of automatic data collection, processing and communication.

Purpose: The purpose of this study was to analyze effects of a community-based case management program for clients with hypertension living in the community. Methods: The research design was a one group pre and post-test design with 30 participants with hypertension who agreed to participate in the 8-12 week case management program provided by case managers from the National Health Insurance Corporation in 2002. Data were collected three times, before and after the case management services, and 6 months later. Outcomes included changes in blood pressure, knowledge of hypertension and daily life practices, including alcohol consumption, smoking, exercise, and medication adherence. Results: Repeated-measures ANOVA and post-hoc tests of means revealed significant differences before and after service for systolic blood pressure, daily life practices (monitoring body weight and BP, low salt and cholesterol and high vegetable diet, and stress-relief practices), and exercise. The goal for medication adherence was attained after service. Significant improvements from baseline to 6 months after service were observed in measures of salt and vegetables in diet. There were no significant differences on hypertension knowledge, alcohol consumption or smoking behavior between before service and after, and at 6 months. Conclusion: The findings provide preliminary evidence that case management intervention can have positive outcomes on BP control, daily life practices, exercise, and medication adherence for clients with hypertension. However, additional interventions are needed to sustain long-term effects.

Objective : The purpose of this study was to investigate the effects of yoga program on depression, quality of life, and difficulty of daily activities in community elders. Methods : A Nonequivalent control group pretest-posttest design was used for this study. Elderly people who agreed to participated in the study were assigned to a experimental group(n=17) or a control group(n=17). The yoga program conducted 90minutes, 2times a week for 1 year. Study outcomes were measured by structured questionnaires from March, 2012 to Feb., 2013. For data analysis, Chi-square test, t-test, and Mann-Whitney U test were performed using SPSS version 17.0. Results : Depression was not significant difference between the two groups in pretest and posttest. But there was significant differences between the two groups in quality of life (t=3.984, p<.001), and difficulty of daily activities (t=-3.083, p=.004). Therefore, the experimental group showed significant improvement in quality of life and reduce difficulty of daily activities. Conclusion : The yoga program was effective in increasing quality of life and decreasing difficulty of daily activities in community elders. When developing exercise program to improve health in older adults, it is important to consider physical exercise plus general health management.

I conducted extensive analyses of daily weather data of precipitation and temperature monitored from the Surface Synoptic Meteorological Station in Seoul from 1 October 1907 to 31 December 2009 to understand how the climate is changing and the ecological implications for Seoul, Korea. Statistical analyses of the data, including the lengths of seasons and growing degree-days (GDD), showed a clear warming trend in the Seoul area over the study period. The mean daily temperature in Seoul increased by $2.40^{\circ}C$ over the period of one hundred years, which was about three times faster than the global trend and it was striking to notice that mean daily temperature in Seoul in recent 30 years was increasing with the rate of $5.50^{\circ}C$ per hundred years, which is an extremely fast rate of increase in temperature. In the last 100 years, an increase in the number of summer days was apparent, coupled with a reduction in the average number of winter days for about 27 to 28 days based on the analysis of mean daily temperature. Although the lengths of spring and autumn have not changed significantly over the century, early initiations of spring and late onsets of autumn were quite apparent. Total annual precipitation significantly increased at the rate of 2.67 mm/year over the last 100 years, a trend not apparent if the analysis is confined to periods of 30 to 40 years. The information has the potential to be used not only for better understanding of ecological processes and hydrology in the area, but also for the sustainable management of ecosystems and environment in the region.

Both direct and indirect courses are studied in this research to study the effect of fathers' daily stress, child-rearing involvement and marital conflict on children's emotional intelligence. The participants were 281 parents of children aged between 3 to 5 attending 9 kindergartens in Seoul and the Gyeonggi-do, Jeolla-do, and Gyeongsang-do areas. The data was collected by the questionnaire method. Collected data for the study was analyzed using the Structural Equation Model with the AMOS 16.0 program. The main points of this research are as follows: First, the direct course of fathers' daily stress did not appear to have a significant effect on children's emotional intelligence. Second, fathers' daily stress has an indirect effect on children's emotional intelligence through marital conflict. That is, the higher level of stress in the father's daily life, the deeper marital conflict that is found. And the deeper the marital conflict that exists, the lower child's emotional intelligence that is shown. Third, the direct course of the fathers' child-rearing involvement did not appear to have a significant effect on children's emotional intelligence. Fourth, the father's child-rearing involvement has an indirect effect on children's emotional intelligence through marital conflict. That is, marital conflict decreases as the father becomes more involved in child rearing. In addition, the lower level of marital conflict that exists, the higher child's emotional intelligence.

In the daily multi-reservoir operating problem, monthly storage targets can be used as principal operational guidelines. In this study, we tested the use of a simple back-propagation Artificial Neural Network (ANN) model to derive monthly storage guideline for daily Coordinated Multi-reservoir Operating Model (CoMOM) of the Han-River basin. This approach is based on the belief that the optimum solution of the daily CoMOM has a good performance, and the ANN model trained with the results of daily CoMOM would produce effective monthly operating guidelines. The optimum results of daily CoMOM is used as the training set for the back-propagation ANN model, which is designed to derive monthly reservoir storage targets in the basin. For the input patterns of the ANN model, we adopted the ratios of initial storage of each dam to the storage of Paldang dam, ratios of monthly expected inflow of each dam to the total inflow of the whole basin, ratios of monthly demand at each dam to the total demand of the whole basin, ratio of total storage of the whole basin to the active storage of Paldang dam, and the ratio of total inflow of the whole basin to the active storage of the whole basin. And the output pattern of ANN model is the optimal final storages that are generated by the daily CoMOM. Then, we analyzed the performance of the ANN model by using a real-time simulation procedure for the multi-reservoir system of the Han-river basin, assuming that historical inflows from October 1st, 2004 to June 30th, 2007 (except July, August, September) were occurred. The simulation results showed that by utilizing the monthly storage target provided by the ANN model, we could reduce the spillages, increase hydropower generation, and secure more water at the end of the planning horizon compared to the historical records.

PURPOSE: To investigate the validity of a smartphone application for post-stroke daily living activity management based on an evaluation by users and experts. METHODS: The study design adhered to the analysis, design, development, implementation, and evaluation ADDIE (Analysis-Design-Development-Implement-Evaluation) model. We downloaded the application onto the smartphones of 33 users and 30 experts, taught them how to use it, and asked them to use the application for four weeks. The users' daily lives before and after using the application were compared based on the K-MBI (Korean Version of Modified Barthel Index) to evaluate the usability of the application. For the expert group, we investigated the content validity and reliability of the application and evaluated the usability of the application. Data were analyzed using the SPSS 21.0 software. Users' general characteristics and experts' evaluation scores were analyzed using descriptive statistics. Content validity was tested using the content validity index (CVI), and reliability was tested with Cronbach's alpha. Users' K-MBI scores before and after using the application were compared with the paired sample t-test. RESULTS: Users gave an average rating of 2.93 out of 4 for the application for managing the daily lives of stroke patients, while experts gave an average score of 3.14. With regard to the K-MBI scores, only the dressing score improved significantly (p<.005) after using the application, and scores for other categories slightly improved but not to significant levels. CONCLUSION: The results of this study suggest that the STROKECARE application is usable and could help stroke patients manage their daily lives.
