Most construction works in a building site are progressed by many work categories and sub-contractors. Therefore there are many difficult things of management of construction-information because variable occurrences are happened to manpower and material resources. For this reason, various management systems are suggested, but the application of these systems are difficult because only construction company manages these systems and sub-contractor's participation, understanding and financial ability are insufficient. In addition to that, there are other problems such as lost information when it is carried, perversion and distrust of information by hand and lots of time and labor are necessary for collection, analysis, and management of information which are offered for daily report. so the purpose of this study is for improvement of reporting process with making an analysis of productivity effects and an analysis of function and problem of daily report. I intend to suggest the direction of improved daily report system for better productivity of construction work through input information and management of cooperation enterprises.

A daily report is one of the critical documents in construction projects, since it helps them keep track of various as-built information. Despite the important role in progress management, the daily reporting process is time-consuming, and the representation of task information on daily reports are not effective enough to accumulate daily as-built information for further use in project management. Task information is composed of a specific work type and a location where the task is performed, which means that the same type of work is repeated over the locations. However, in many cases the task locations are described differently depending on a reporter's preference or experience. Without representing task location information effectively, it is difficult to accumulate and to reuse as-built information. The objective of this research is to build a framework for generating task information which can be efficiently accumulated and reused for progress management. To do so, this research built a task information model with focusing on the representation of task location associated with a work type, and developed an information system that supports automated and interactive generation of task information.

Objectives : The purpose of this study was to analyze the relationships among social participation, self-rated health status, self-esteem and daily life satisfaction of the elderly with disabilities. It especially focused on the mediating effects of self-rated health status and self-esteem on the relationship between social participation and daily life satisfaction. Methods : From the fifth panel survey of employment for the disabled, data for 518 elderly over age of 65 were analyzed with SPSS 22.0, SmartPLS 2.0 M3 and the Sobel test. Results : First, social participation of the elderly with disabilities had a positive influence on the self-rated health status and self-esteem. The direct effect of self-rated health status and self-esteem on daily life satisfaction was statistically significant. However, the influence of social participation on daily life satisfaction was not statistically significant. Second, the self-rated health status and self-esteem had a mediating effect on the relationship between social participation and daily life satisfaction. Conclusions : This study shows that it is important to provide an integrated social participation support program that coincides with a variety of social programs to elderly with disabilities.

It is important to analyze the status of water quality with relation to the stream flow to attain water quality goal more effectively in the unit watersheds for the management of Total Maximum Daily Loads (TMDLs). This study developed a flow duration-water quality distribution graph to figure out water quality appearances on the flow variation and analyzed contributions of water quality observations to the impaired water bodies quantitatively by hydrologic conditions. Factors relating to water quality variation can be analyzed more precisely and assessed on the base of quantified contributions. It is considered that this approach could be utilized to establish a more effective plan for the water quality improvement including the prioritization of pollution reduction options.

The purpose of this paper was to investigate the relations among wife's job and family life structure of couples, and to compare them between Japan and Korea. The data for this study was obtained from a survey of 247 Japanese couples who were risiding in Osaka and 235 Korean couples in Deagu, 1992. The major findings of this study can be summarized as follow: 1. The contents of Household works is classified into three factors-daily routine houseworks, child-rearing, economic-management of household, in Korea, and into two factors-daily routine houseworks, child and economic management, in Japan. The contents of descision making is classified into four factors-husband's personal sphere, family life management, wife's personal sphere, and home economic sphere, in Korea, and three factors-husband's personal sphere, economic life management of family, and wife's personal sphere, in Japan. 2. In Korea and Japan, wife's job have not effect on couple's marital satisfaction, directly. However, wife's job contribute to husband's share of daily routine houseworks.

The management of blood inventory is very important within the medical care system. The efficient management of blood supplies and demands for transfusions is of great economic and social importance to both hospitals and patients. For any blood type, there is a complex interaction among the optimal inventory level, daily demand level, daily supply level, transfusion to crossmatch ratio, crossmatch release period, issuing policy and the age of arriving units that determine the shortage and outdate rate. In this paper, we develop an efficient decision rule for blood inventory management in a hospital blood bank which can support efficient hospital blood inventory management using simulation. The primary use of the efficient decision rule will be to establish minimum cost function which consists of inventory levels, period in inventory, outdate and shortage rate for whole blood and various component inventories for a hospital blood bank or a transfusion service. If the administrator compute the mean daily demand for each blood type, the mean daily supply for each blood type, the length of the crossmatch release period and the average transfusion to crossmatch ratio, then it is possible to apply the efficient decision rule to compute the optimal inventory level, inventory period, outdate and shortage rate. This rule can also be used as a decision support system that allows the blood bank administrator to do sensitivity analysis related to controllable blood inventory parameters.

The management of daily work report is very important due to the variety of work trade and activities. Although various project management systems have been developed to effectively deal with various task in site, they are not in practical use due to the non-coorperative attitude of sub-contractors. This is the reason the system are not developed in the focus of sub-contractors, but main contractors and the detail information about daily work report is omitted or lost in the collection process by contractors. Therefore the purpose of this study was to propose the Web-based coordination system for daily work report between contractor and sub-contractors

Purpose: The purpose of this study was to develop and evaluate a self-management program for community dwelling patients with chronic mental illness so that they could improve their daily living skills and interpersonal relationships. Methods: A nonequivalent control group pre-post test design was used. The participants with chronic mental illness were recruited from a community mental health center. Twenty-two participants were assigned to the intervention group and 19 to the control group. The self-management was provided by 8 trained nursing students, and consisted of 8 sessions including education and practice. Each session was composed of strategies to improve self-care of community dwelling patients with chronic mental illness. Baseline and post-intervention measurements were done using a daily living skill performance scale and interpersonal relationship instrument. Results: Scores for daily living skill performance were not statistically significant, but scores for interpersonal relationship were statistically significant. Conclusion: The results of this study show that the self-management program had a positive impact on patients with chronic mental disorders. Therefore, it is suggested that the program could be used as an effective nursing intervention for patients with chronic mental disorders being cared for in community mental health centers.

Flow duration curve (FDC) can be developed by linking the daily flow data of stream flow monitoring network to 8-day interval flow data of the unit watersheds for the management of Total Maximum Daily Loads. This study investigated the applicable method for the development of long term FDC with the selection of the stream flow reference sites, and suggested the development of the FDC in 4 river basins. Out of 142 unit watersheds in 4 river basins, 107 unit watersheds were shown to estimate daily flow data for the unit watersheds from 2006 to 2010. Short term FDC could be developed in 64 unit watersheds (45%) and long term FDC in 43 unit watersheds (30%), while other 35 unit watersheds (25%) were revealed to have difficulties in the development of FDC itself. Limits in the development of the long term FDC includes no stream monitoring sites in certain unit watersheds, short duration of stream flow data set and missing data by abnormal water level measurements on the stream flow monitoring sites. To improve these limits, it is necessary to install new monitoring sites in the required areas, to keep up continuous monitoring and make normal water level observations on the stream flow monitoring sites, and to build up a special management system to enhance data reliability. The development of long term FDC for the unit watersheds can be established appropriately with the normal and durable measurement on the selected reference sites in the stream flow monitoring network.

The objective of this study is to investigate a perceived discomfort and cause of Korean elderly in various activities such as work and leisure as well as in daily activities. 120 subjects (30 female and 30 male for each age: the young and elderly) participated in the interview type of questionnaire. Each participant answered to 41 items of activities of daily living. The examination of each item was progressed with 3 steps: whether to do the activity or not, degree of activity discomfort, and the reasons or causes of discomfort. Borg's CR10 scale is used to measure the degree of discomfort of daily activities. As a result, there are differences for the proportion of performers between two age groups, except for essential activities such as individual maintenance and housekeeping. The elderly complained about their daily activities more than the young did, and the degree of discomfort of women was significantly larger than that of men with aging. There are seven items, the mean degree of discomfort of which is over three points for the elderly, and they showed significant difference between two age groups. It was the important reason that physical capacities such as muscle strength and suppleness are declined. The results showed the characteristics of Korean elderly in the whole daily activities. These will be used to understand various life styles of them and to propose a field or direction of study related to the aging.
