Childcare related studies have focused on the characteristics of care work, policy aspects, user family satisfaction, and job satisfaction of childcare helpers. But there have been few studies on family system characteristics that support childcare givers. Thus, this study conducted on the topic, "How to characterize the family resilience of long-term childcare givers?" The subjects belong to a healthy family support center in U. City, who belong to a group with an income in the top 20 % of about 20 persons working for more than 3 years. In an interview, qualitative questions were used Walsh's family resilience. The results are as follows. First, they had economic hardship, but their family would stand together and build up a family's power based on the couple's faith. They had a family role model based on their parents' family that included inherited maternity qualities from their mother. Second, the flexibility of the family organization changed to autonomous or co-role type and the connectivity. Especially, they appear as a family's leader. Third, their family communication was active, shared-care, responsible and passionate with family affection and understanding. The conclusions results are as follows. Participants were high school graduates as well as had work experience. They were characterized by positive family energy, a family belief system, family-based resources, flexibility, connectivity, open family communication and expression skills. Therefore, it can be suggested that it is necessary to check the family's resilience during an interview for the reliable, long-term supply of human resources for childcare activities.

Since the protection the of human being from natural disaster and atmospheric factors have become an essential requirement, some attempts have been taken place to provide shelter and create a safe environment to a more comfortable life with welfare. For this purpose, using existing resources in nature and exploiting them in a different manner have been taken into account. Initially, the performed exploitations for construction had the least damage to the environment, but over time and as a result of population growth, aggressive exploitation of nature has led to destroying effects on the environment and resulted in consequences such as pollution and environmental destruction. Thus, the construction industry has been identified as the top pollutant factors of the environment. Among various construction factors, the building materials used in this industry are considered as the most important effective factors on the environment, as they have direct influences on the environment from the beginning of construction of the final steps. This research focuses on the review of the most of the existing green materials definitions and various approaches towards using eco-efficient construction materials. It presents and discusses possible ways of reducing the destructive effects on the environment by selecting and using green materials, review current literature and highlight the necessity of applying such materials in future constructions in all communities. This paper provides a base for this purpose that sustainable development communities and environment is realized by elimination of environmental pollution and approaching the criteria of green building by using sustainable materials.

The principal objective of this study was to assess the nutritional status and dietary quality in low-income elderly individuals residing at home (LH) or in health care facilities (LHCF) with dietitian. This study was conducted via anthropometric measurements, questionnaire interviews, and dietary surveys using a 24 hr recall method with 120 low-income elderly individuals (LHCF=46, LH=74). The average ages of the LH and LHCF group were 76.3 years and 78.6 years, respectively. The LH group evidenced a significantly higher frequency of skipping meals than the LHCF group. The average energy intakes of the LHCF and LH group were 1921.0 kcal and 1443.9 kcal, with a significant difference (p<0.001). Most of the nutrient intake and intake rates for recommended intake were significantly higher among the LHCF group as compared with the LH group. The LHCF group showed significantly higher values for the nutrient adequacy ratio (NAR), the mean adequacy ratio (MAR), nutrient density (ND), and the index of nutritional quality (INQ) by dietary qualitative estimation than in the LH group. The Korean diet diversity scores (KDDS) were 3.66 for LH group and 4.93 for the LHCF group, thus were significantly higher in the LHCF group than in the LH group. The results of the present study demonstrate that the LH group appeared to experience more dietary problems than the LHCF group. It was suggested that nutritional education is needed for low-income elderly individuals living at home, in order for them to learn proper dietary management. This can be achieved via educational programs in social welfare institutions, incentives toward employment as a dietitian, and implementation of community-based support.

The present study has quantitatively assessed the regional production, income and employment impact resulting from the construction and operation of nuclear power plant (NPP) upon the domestic local areas by applying the regional input-output analysis model to the case of Wolsong unit-l site. The conclusions regarding the most likely regional economic impacts upon the wolsong site are summarized as follows: 1. The income multipliers are calculated to be 1.563 for the construction phase and 1.500 for the operation phase. These values are relatively high compared with those of other conventional facilities. 2. The level of total employee's wage induced employment associated with the construction phase has been estimated to be 37,000 while that with the operational phase in 1990 to be 5,610. 3. With relation to the aspect of resident welfare it is found that the industrial sector associated with electricity, gas and water supply have remarkably improved with the construction of the NPP. 4. The NPP siting has induced substantial changes in interindustry (input-output) structures of the Wolsong unit-l site which is one of the rural areas where all the domestic NPPs are sited. Such changes are attributed to the industrial recomposition of the region. 5. With the application of other regional economic analysis models and the use of more sufficient regional data, other detailed studies on the economic impact analysis of domestic NPP-related facility sitings are suggested to be carried out further since the influence of NPP sitings is significant to the national economic impact as well as the regional economic impact.

A biomarker is needed to monitor and manage the health of pigs from heat stress (HS). Therefore, we investigated the effects of HS on growth performance, nutrient digestibility, and blood profiles in finishing pigs. A total of 12 finishing pigs (n = 12) were raised in thermal neutral (TN; 25℃) conditions for a 3-d adaptation period. After the adaption, 6 pigs were exposed to HS at 33℃ (HS33) for 5 d. The pigs were fed the same diet based on corn and soybean meal. Chromic oxide was added to all the diets at a level of 2 g·kg^-1 as an indigestible marker for the determination of the apparent total track digestibility (ATTD) of nutrients and amino acids. Blood samples were collected after the adaptation and heat treatment to verify the blood profiles. The HS33 pigs had a lower (p < 0.01) average daily feed intake (ADFI) and higher (p < 0.05) rectal temperature compared to the TN pigs. However, there was no difference in the ATTD of nutrients and amino acids. The HS33 pigs had reduced (p < 0.05) levels of serum glucose, non-esterified fatty acids (NEFA), total protein, albumin, and calcium compared to the TN pigs. However, the level of total bilirubin was increased (p < 0.05) in the HS pigs. In conclusion, HS reduced the feed intake and had an adverse effect on health. Altered blood profiles as a result of a negative energy balance are expected to be biomarkers of HS in finishing pigs.

Purpose: Number of the old-old elderly is rapidly increasing in Korea, but it is unclear whether there are differences between old-old and young-old elderly in nutritional status, nutrient intakes and health status. The gender differences in Korean elderly in these conditions also remains unknown. This study, therefore, investigated gender-associated differences in nutritional, health status and nutrient intakes and how they are related among young-old and old-old homebound elderly. Methods: Two hundred and eighty elderly who were attending a local elderly welfare center were recruited. Evaluation included demographic, nutritional and health status related data, nutritional intakes, and life style related factors including physical activity. Results: Of the 280 subjects, old-old were 147 (52.5%) and young-old were 133 (47.5%). Male old-old elderly had more often abdominal obesity than female old-old, but male old-old more often had malnutrition than female old-old. There were few differences in nutrient intakes between old-old male elderly and female elderly after energy intakes were controlled. Male old-old more often had less intake of beta carotene and Vitamin A than female old-old. On the other hand, male old-old elderly more often had hypercholesterolemia and hypertension than male young-old. Conclusion: Male old-old may be at a greater health and nutritional risk than female old-old. Targeted nutritional intervention for male old-old emphasizing antioxidant nutritional intakes may be warranted.

This study evaluates a novel scheme to trade sulfur dioxide emission permits subject to non-uniform rates. These rates are based on generators' marginal costs of compliance with environmental policy in a hypothesized least social-cost solution. This scheme is compared against the existing trading program used by the U.S. Environmental Protection Agency, featuring permits tradable one for one. Both policies are modeled to yield identical aggregate emissions. A numerical partial-equilibrium model of the U.S. energy industry is used to infer sulfur dioxide concentrations and health damages, as well as producer and consumer surplus, under the two policies. Regional pollution levels are found to vary across the two policies significantly. The system of exchange rates is estimated to outperform the uniform-trading scheme by $2.2 billion in industry profits and $2.1 billion in health damages, but to reduce consumer surplus by $6.7 billion. Paradoxically, exchange rates are thus estimated to lower total welfare by $2.5 billion. This is due to conceptual mechanism-design problems, as well as empirical issues.

This study was carried out to investigate the nutritional status of physically handicapped children with cerebral palsy in order to contribute to their welfare by studying their healthy status, nutrient intake, daily energy expenditure, and living environment. The survey was conducted at two rehabilitation institutions from May 25 to June 30, 1981. A special questionnaire was designed to investigate the living environment. The 24 hr. recall method was used in evaluation the nutrient intake of 67 children. Anthropometric measurement was made of height, weight, chestgirth, upper-arm circumference, and triceps skinfold thickness. The biochemical status of the children with cerebral palsy was assessed with measurement of hemoglobin and hematocrit. The results may be summarized as follows : 1. The children with cerebral palsy, the intakes of all nutrients except vitamin A, thiamin, and ascorbic acid were lower than Korean recommend dietary allowances (1980). They had significantly higher intakes of vitamin A and calcium than the normal children, but the calcium intake was low as 62% of the Korea RDA. 2. All the children with cerebral palsy were very short and low weight in comparison with the accepted standards, but chestgirth was above the accepted standards for Korean school children. 3. The average hemoglobin value was 12.2gm%, hematocrit 39.3%, and mean corpuscular hemoglobin concentration (MCHC) 31.1%. 4. The possible etiological factors of cerebral palsy were, prenatal factors 16%, natal 44.9%, postnatal 27.5%, and unknown 11.6%. Eighty four percent of the children showed their first symptoms within the first year after birth. 5. Thirty percent of the parents said that the handicapped children lead to marital problems, and 84.1% of the parents mentioned that medical expenses for the children influenced their family finances.

This research is to suggest a method for investigating car number plates among the information managed in parking facilities. The investigation of car number plate is generally used to know how long vehicles are parked. Also, it can provide the information about the parking turnover rate and the mean parking duration of parked vehicles. This research performs the investigation using cameras at a distance of time. That is, the given distance of time from cameras is assigned to each parked vehicle, and then it can find the mean parking time of parked vehicles. Also, it can check the parking turnover rate of parked vehicles at a space unit of parking lot in an hour. The information such as the mean parked duration and the parking turnover rate of parked vehicles taken from this method is helpful to find and understand the inefficient use of parking facilities. With this suggested method, this research attempted to check the mean parking duration and the parking turnover rate of parked vehicles.
