Home health care is one of the important components of health care services. Today, the need and demand for the home health care is increasing. To assess the effects of home visit health services by public health nurses in health center on the stat of health, use of medical services and quality of life by elderly people living at home, a randomized controlled trial was implemented for 65 years or more old people randomly allocated to intervention(93) and control(118) group. Intervention group received 2 visits a month over 6 months. Control group received no home visits. The data was collected in a one-year follow-up survey conducted at Kyongju before and after the intervention which composed of health risk assessment, risk factor education and health related behavior counseling. The prevalence rate of chronic illness was more decreased in intervention group than control group after intervention. The intervention group visited medical facilities less frequently than control group. And the home visit health services encouraged the elderly to practice regular exercise. After the intervention, the score of ADL(activities of daily living), LSI(life satisfaction index) and SSI(social support index) in intervention group were more increased than control group. And the increase of scores was more prominent in 70 years or more old people, female, non-smoker and non-chronic illed elderly rather than others. In conclusion, the regular home visit health services provided by public health nurses were beneficial for the elderly in terms of health promotion and quality of life.

Drought is a major limiting factor that reduces rice production and occurs often especially under recent climate change. Plants have the ability to alter their developmental morphology in response to changing environment, which is known as phenotypic plasticity. In our previous studies, we found that one chromosome segment substitution line (CSSL50 derived from Nipponbare and Kasalath crosses) showed no differences in shoot and root growth as compared with the recurrent genotype, Nipponbare under non-stress condition but showed greater growth responses compared with Nipponbare under mild drought stress condition. We hypothesized that reducing root respiration as metabolic cost, which may be largely a consequence of aerenchyma formation would be one of the key mechanisms for root plasticity expression. This study aimed to evaluate the root respiration and aerenchyma formation under various soil moisture conditions among genotypes with different root plasticity. CSSL50 together with Nipponbare and Kasalath were grown under waterlogged conditions (Control) and mild drought stress conditions (20% of soil moisture content) in a plastic pot ($11cm{\times}14cm$, ${\varphi}{\times}H$) and PVC tube ($3cm{\times}30cm$, ${\varphi}{\times}H$). Root respiration rate was measured with infrared gas analyzer (IRGA, GMP343, Vaisala, Finland) with a closed static chamber system. There was no significant difference between genotypes in control for shoot and root growth as well as root respiration rate. In contrast, all the genotypes increased their root respiration rates in response to mild drought stress. However, CSSL50 showed lower root respiration rate than Nipponbare, which was associated by higher root aerenchyma formation that was estimated based on internal gas space (porosity) under mild drought stress conditions. Furthermore, there were significant negative correlations between root length and root respiration rate. These results imply that reducing the metabolic cost (= root respiration rate) is a key mechanism for root plasticity expression, which CSSL50 showed under mild drought.

Lactoferrin is an 80-kDa iron-binding glycoprotein known to exert many biological activities, such as facilitating iron absorption and having antimicrobial and anti-inflammatory effects. Rice can be a useful target for edible food plants to introduce human lactoferrin, because it has lower allergenicity and is likely to be safer than microorganisms or transgenic animals. A cDNA fragment encoding human lactoferrin (HLF) driven by the maize polyubiquitin promoter, along with herbicide resistance gene (bar) driven by CaMV 35S promoter, was introduced into rice (Oryza sativa L. cv. Dong Jin) using the Agrobacterium -mediated transformation system. Putative transformants were initially selected on the medium containing bialaphos. The stable integration of the bar and HLF genes into transgenic rice plants was further confirmed through polymerase chain reaction (PCR) and Southern blot analyses. The expression of the full length HLF protein from various tissues such as grains and young leaves of transgenic rice was verified by Western blot analysis. Analysis of progeny also demonstrated that introduced genes were stably inherited to the next generation at the Mendelian fashion.

This study aims to provide information about the acute poisoning patients transferred by 119 ambulance service for nurses and emergency medical technicians. The data is based on 119 ambulance services patients charts of Seocho area in Seoul. The results were as follows: 1. Total number of emergency patients all over the country has been nearly fourtimes in 1995 compared to 1991. Total number of emergency patients were 322.051 in 1994. 2. About $35\%$ of total E.R. patients were transferred by 119 ambulance services in Seoul in the last 5years. Acute drug intoxication patients occupied $2-3\%$ of E.R. patients in Seoul. 3. About $4\%$ of E.R. patients in Seoul were transferred by 119 E.R. services of Seocho area in Seoul in 1995. Among them $2.4\%$ patients were drug intoxication patients. 4. Data were collected from available patients of 119 ambulance services from Jan. 1993 to Dec. 1995 in Seocho area. Total poisoning patients were 184. - The female/male ratio was 69.7:30.4 and most of patients$(69.7\%)$ were in the age of 20th and 30th. - The busy time of calling 119 ambulance service was from 6P.M. to midnight$(37.5\%)$ - It took within 10 minutes for patients$(62.8\%)$ from notification to arrival in hospital. - Regarding poisoning substances. hypnotics $(22.8\%)$, tranquilizer$(14.7\%)$, agricultural agents$(6.0\%)$ rodenticide$(27\%)$ and others $(10.3\%)$ were in order and unknown were $43.5\%$. - Most of the patients or protector $(72.8\%)$ chose hospitals. Among them $(87.3\%)$ were general hospital. - The most predominant symptoms were coma$(22.3\%)$. dizziness$(6.5\%)$ and then allergy. vomiting. gastrointestinal cramps etc. - Airway management and oxygen administration together was the main medical control of prehospital emergency medical services$(33.7\%)$. It is proposed that first, a systematic survey of drug intoxication patients must be conducted to give an appropriate prehospital emergency care for the emergency medical technician and second, a wide and regular public education to improve understanding of first aids should be undertaken.

Despite its universal coverage of health insurance, the rural health insurance program(RHIP) stands at the crossroads in Korea. The RHIP has weaknesses in stability of financing, problems of inequities in the provision of health services and has suffered from high cost of running the program. The author has analyzed these problems from the perspective of health insurance policy and presented several options for improvement. First of all, this study urged the importance of a firm Governmental commitment of RHIP with the 50% subsidization of contributions as the Government had promised, instead of the current 40%. This can be justified from the 20% subsidization by the Government for the contributions of private school teachers and their dependents, who belong to richer segments of the population. Second, various cost containment measures ought to be sought curbing the rising demand for medical through strengthening health education and increasing individual responsibility, and tightening the claim review process. Third, this study requires the Government to run a demonstration project on the introduction of case payment system for primary health care. Fourth introducing an income-related cost sharing scheme is another possibility. Reforming the cost sharing formula for large medical expenditures is recommendable for a beginning. This measure can take the form of tax credit for medical expenditures of the poor. Fifth, the degree of financial adjustment among health insurance plans should be levelled up for enhancing stability of RHIP and social solidarity. Sixth, health policy should be redirected toward development of rural health resources and higher priority should be put on relieving difficulties in access to care. Seventh. the insurance plan owned-hospital needs to be developed or provision of health services in the medically underserved areas, and the need of such facilities is particularly acute for geriatric care, rehabilitation and renal dialysis, etc. Eighth, more generous insurance benefits are required of the elderly who are suffering the most : elimination of the maximum 180 days of benefit period and provision of glasses and artificial dentures, etc. Ninth. the economies of scale principle is working for the operating expenses of regional self-employed insurance plan. Thus, measures should be instituted to pursue an optimum size of health insurance plans. Lastly, excessive dependence on exclusion items is an evil so that some radical remedies are urgently required to cut them.

Musculoskeletal disorders are a major cause of occupational disabilities. Approximately thirty percent state that the major reason for an inability to work is a musculoskeletal problem. A farm work is associated with increased stress and trauma to joints. Chronic overuse injuries are a result of stresses that exceed the body's adaptive or healing capabilities. They can occur in bone, tendons and muscle-tendon-bone junctions. The aim of the investigation was to the study the frequency of pain, ache, and discomfort in the musculoskeletal system among farmers, to find possible correlations between these symptoms and various working positions and different working actions. A questionnaire was answered by 138 farmers. Of those who answered the questionnaire 82% had pain and discomfort from back, shoulders, arms in orders, The result showed that musculoskeletal pain predominate in the farming seasons, and of those who had pain and discomfort 89% thought that farm works had a correlation with the pain and discomfort of musculoskeletal system. But only 17% of quationnaire were put to periodic medical examinations, and 50% of those who had pain and discomfort consulted a doctor. Education in effective pain treatment should therefore be intensifide to ascertain that farmers in rural areas have satisfactory knowledge of the musculoskeletal pain as a chronic overuse syndrome.

Objectives: This study was conducted to investigate how willingness to have an additional childbirth was related to mother's general characteristics and various reasons for avoiding an additional childbirth. Methods: By using organized questionnaire, we had face-to-face interviews with 722 mothers who had 12 to 36 months child in a urban-rural area of Chungcheongnam-do from 14 February to 19 February in 2005. Questionnaires included general characteristics composed of age, monthly income, number of children, major carers and mother's job status, and 6 reasons for avoiding an additional childbirth. We performed chi-square test and multiple logistic regression analysis. Results: Of 722 mothers, 66.5% had no willingness to have an additional childbirth. In the multiple logistic regression analysis, old age of mother(95% CI of OR: 1.084-1.190), two or more children(95% CI of OR: 6.97-15.602) and weak norm about need for a child(95% CI of OR: 1.633-29.352) were independent related factors with willingness to have an additional childbirth. Conclusions: In our study, 2/3 women who already had children were appeared to have no willingness to have additional childbirth. Policies about family planning and controlling birth rate should be focused on eliminating barrier to additional childbirths.

This study aims to analyze the housing satisfaction of 55 years and older (55+) single-person householders in U.S. urban communities with the 2011 American Housing Survey Data. Single-person householders younger than 55 years of age (55-) were used as a reference group. Housing Adjustment Theory was used to develop a research framework to depict the relationships of housing satisfaction (dependent variable) with demographic and housing variables (independent variables). The regression analysis revealed that age, health status, government income, race, gender, age of house, housing quality, neighborhood, structure type, and tenure status had a significant effect on housing satisfaction levels of both those aged 55- and 55+. However, for the cohort of 55+, education, census region, housing affordability, and structure size also affected their housing satisfaction. Neighborhood satisfaction had the strongest effect on housing satisfaction of both groups. These variables were discussed in terms of resources and constraints contributing to their housing satisfaction. This study highlights the present and future housing trends and challenges of U.S. single householders in U.S. urban communities.

Objective: The aim of this study was to estimate (co) variance components and genetic parameters for categorical carcass traits using Bayesian inference via mixed linear and threshold animal models in Anglonubian goats. Methods: Data were obtained from Anglonubian goats reared in the Brazilian Mid-North region. The traits in study were body condition score, marbling in the rib eye, ribeye area, fat thickness of the sternum, hip height, leg perimeter, and body weight. The numerator relationship matrix contained information from 793 animals. The single- and two-trait analyses were performed to estimate (co) variance components and genetic parameters via linear and threshold animal models. For estimation of genetic parameters, chains with 2 and 4 million cycles were tested. An 1,000,000-cycle initial burn-in was considered with values taken every 250 cycles, in a total of 4,000 samples. Convergence was monitored by Geweke criteria and Monte Carlo error chain. Results: Threshold model best fits categorical data since it is more efficient to detect genetic variability. In two-trait analysis the contribution of the increase in information and the correlations between traits contributed to increase the estimated values for (co) variance components and heritability, in comparison to single-trait analysis. Heritability estimates for the study traits were from low to moderate magnitude. Conclusion: Direct selection of the continuous distribution of traits such as thickness sternal fat and hip height allows obtaining the indirect selection for marbling of ribeye.

Indonesia is a mega-biodiversity country having at least one trillion US Dollars value of biological resources per year over the next 20 years. Indonesia is home to 11 percent of the world's flowering plant species and 12 percent of all mammals. Many of Indonesia's species and more than half of the archipelago's endemic plant species are found nowhere else on the Earth. This information is just a small portion of all higher plants and animals being found in Indonesia. Former studies described that total number of species in Indonesia is estimated more than 1,000,000 and most of them remain unknown scientifically. Most of lower plants and animals have not been studied yet, so that greatest portion of Indonesia's biological resources has never been assessed with respect to its economic value or conservation status. Many developed countries are building cooperation with Indonesia on resources, mainly in the fields of grant aid, socio-economic services, R & D, researcher exchange, technology transfer, infrastructure, education/training, finance, etc. Indonesia will obtain greater benefits and management of its biological richness via increasing its international capacity to add value and information to its biological diversity. These goals can be achieved by close international collaboration on search of important biological resources and other bioactive products that have potential economic values. Development of biological resource-based technology stands as the industry of the $21^{st}$ century and, therefore, Indonesia has a unique opportunity to lead the process in the world.
