The purpose of this study is to investigate the effects of home informatization on the family resource management. For this purpose we analyze the level of home informatization focused on the Internet use and it's effects on the family resource management through time management and financial management. Data were collected from 582 housewives who use the Internet at home. The results show that home informatization through the Internet use has changed family resource management totally. It contributes to improve planning and efficiency of resource management, but simultaneously it causes the imbalance of resource management. And the Internet use of housewives also affects time allocation and household expenditure. These changes depend on socio-demographics variables, home informatization related variables, and personal resource variables. The results show that the ability to manage time and finance have much more importance to improve the level of planning and efficiency and to decrease the level of imbalance in managerial subsystem. The results of this research suggest several implications for public policy.

The purpose of this study is to investigate the family resource management problems caused by the Internet use. The family resource management problems are composed of time management problem, money management problem and interpersonal resource management problem. And time management problem is perceived as most serious of the three. The perception of family resource management problem is influenced by socio-demographics variables and Internet related variables. Based on the findings, we suggest several implications for education and public policy.

The purpose of this study is to measure the resource use of the elderly in long-term care services and to examine the effects of patient and facility characteristics on their use of resources. The data were collected from 510 old people over sixty years of age, residing in five long-term care hospitals and two skilled nursing homes during the period between December 1, 2000 and February 28, 2001. For a full sample, when the first level of RUG(Resource Use Group)-III categories were employed as the proxy of patient severity, facility characteristics, such as location, size and ownership, have large effects on the resource use measured by service intensity, whereas patient characteristics such as severity have little or no effect. The resource use is significantly high if the facility: (1) is located in rural areas (gun): (2) has mare than 200 beds; (3) is a long-term care hospital; (4) is private; and (5) has a low percentage of medical aid patients. The analysis of the resource use in each RUG-III categories, for which ADL(Ability of Daily Living) were employed as the prosy of patient severity, shows a similar result. The loose relationship between the needs of residents and the resource use seems to be closely associated with the ineffective reimbursement system for providers. The current reimbursement system has no provision for quality improvement and reimburses facilities simply according to their types: fee-for-service for long-term care hospitals, and monthly-flat-rate or full-coverage-national-aid for skilled nursing facilities. It will be necessary to develop a more reasonable reimbursement system that takes patient's severity into account and gives incentives for long-term care providers to offer cost-effective services.

The PERT/CPM are considered as the base procedures for the most successful project scheduling programs. Unfortunately, it is not easy to apply these procedures to real-life projects. This is due to the fact that PERT/CPM assume an infinite number of resources for each activity in project networks. Obviously, the completion time under no constraints is less than when constraints are imposed. One way of approaching this problem is to use heuristic solution techniques. In this paper, we present three heuristics; MRU (Maximum Resource Use) rule, STU (Shortest Time Use) rule, MRUP (Max Resource Use and Period) rule for allocating resources to activities of projects under multiple resource constraints. Comparisons of the project durations show that these heuristic rules are superior to AG3 rule that has been widely used in practice (Elsayed and Boucher, 1994).

Purpose: This study was to classify elderly in long-term care hospitals for using Resource Utilization Group(RUG-III) and to consider feasibility of payment method based on RUG-III classification system in Korea. Method: This study designed by measuring resident characteristics using the Resident Assessment Instrument-Minimum Data Set(RAI-MDS) and staff time. The data were collected from 382 elderly over sixty-year old, inpatient in the five long-term care hospitals. Staff time was converted into standard time based on the average wage of nurse and aids. Result: The subjects were classified into 4 groups. The group of Clinically Complex was the largest(46.3%), Reduced Physical Function(27.2%), Behavior Problem(17.0%), and Impaired Cognition(9.4%). The average resource use for one resident in terms of care time(nurses, aids) was 183.7 minutes a day. Relative resource use was expressed as a case mix index(CMI) calculated as a proportion of mean resource use. The CMI of Clinically Complex group was the largest(1.10), and then Reduced Physical Function(0.93), Behavior Problem(0.93), and Impaired Cognition(0.83) followed. The difference of the resource use showed statistical significance between major groups(p<0.0001). Conclusion: The results of this study showed that the RUG-III classification system differentiates resources provided to elderly in long-term care hospitals in Korea.

Purpose: The purpose of this study was to classify the elderly in long-term care facilities using the Resource Utilization Group(RUG-III) and to examine the feasibility of a payment method based on the RUG-III classification system in Korea. Method: This study measured resident characteristics using a Resident Assessment Instrument-Minimum Data Set(RAI-MDS) and staff time. Data was collected from 530 elderly residents over sixty, residing in long-term care facilities. Resource use for individual patients was measured by a wage-weighted sum of staff time and the total time spent with the patient by nurses, aides, and physiotherapists. Result: The subjects were classified into 4 groups out of 7 major groups. The group of Clinically Complex was the largest (46.3%), and then Reduced Physical Function(27.2%), Behavior Problems (17.0%), and Impaired Cognition (9.4%) followed. Homogeneity of the RUG-III groups was examined by total coefficient of variation of resource use. The results showed homogeneity of resource use within RUG-III groups. Also, the difference in resource use among RUG major groups was statistically significant (p<0.001), and it also showed a hierarchy pattern as resource use increases in the same RUG group with an increase of severity levels(ADL). Conclusion: The results of this study showed that the RUG-Ill classification system differentiates resources provided to elderly in long-term care facilities in Korea.

Total Economic Value (TEV) provides a framework to estimate the economic value of water resources including groundwater with multiple applications to natural resource economics and environmental economics. Crucial to the application of economic analysis to natural resources are techniques to value the resources as an economic value that is expressed in monetary terms. On the other hand, the aim of TEV estimation is to determine the economic value of water resources including 'use' with production and recreation and 'non-use' such as existence values. TEV is used to assess the economic value of water resources for the multiple goods, and environmental 'services' that are provided by a water resource and also used to assess options for water use, for example balancing production values provided by water resource use against the cost of resource degradation by that use. The value of TEV can be assessed over time where pollution or unsustainable use may reduce the economic value of an environmental asset. Therefore, values are used to assess options of resource use, sometimes leading to policies on resource conservation or allocation. In conclusion, the application of TEV would be well adjusted over Jeju Island where groundwater resources account for more than 98% water resources and the budget of water demand/supply shows disparity over the Island.

IoT devices frequently require input resources to communicate with various sensors or IoT platforms. IoT device wastes a lot of time as idle time or waiting time to check the data of the input resource and use the input resource. In addition, IoT devices use various input resources. We compares and analyzes input idle time and input waiting time generated from hardware serial input resource, software serial input resource, digital port input resource, and analog port input resource using Arduino widely used as IoT device. In order to design the IoT device framework, it is necessary to understand the characteristics of input resources and to design them to minimize unnecessary input idle time and input waiting time. The analog input wait time has a much larger input wait time than the digital input wait time, so it must be designed to receive analog information periodically at the appropriate timing. The characteristics of the input resources analyzed in this way help to design an efficient IoT device.

With the increasing concern about natural resources that is being devastated and lost its reproductivity, Non-use value of resources for future use is considered more important than the present use value in the resource valuation. This study aims to measure Total Non-use value in Namsan Park, Kwanak and Paldal Mountain with CVM(Contingent Valuation Method). CVM is the method which can evaluate Non-use value of tourism resource to find the future value of the given resource. This study is carried on the assumption that respondents give answers not to real situation but to imaginary circumstances. After analysing benefit value by estimating conservation value and separate use value, we can conclude that conservation value of tourism resource is given much weight.
