A research team from the Center for Health Promotion (CHP) at the University of Toronto published a book entitled “Quality of Life in Health Promotion and Rehabilitation” in 1996. In this paper we will introduce the conceptual models of QOL made up of the components of QOL and the QOL field presented by the CHP researchers. They defined QOL as “the degree to which a person enjoys the important possibilities of his or her life” and proposed a QOL model comprised of nine measurable areas, which are grouped into three broad categories of “Being, ”“Belonging” and “Becoming.” The “Being” cluster encompasses the most basic aspects of human beings as individuals, consisting of such three sub-components as physical, psychological and spiritual being. The “Belonging” cluster is concerned with the fit between individuals and their environment, consisting of social, community and ecological belonging. The “Becoming” cluster focuses on the purposeful activities in which individuals engage in an attempt to realize their goals, aspirations and hopes, consisting of practical, leisure and personal growth becoming. In the QOL field as a conceptual model of comprehensive health and well-being and QOL framework, QOL is viewed as the result of identifiable determinants, divided into environmental and personal categories in interaction with such moderating conditions as control, potential opportunities, resources, support systems, skills, life events, political changes and environmental changes. Recently the importance of understanding health issucs at community level from the ecological and phenomenological viewpoints and of directing our attention to the people's living has been recognized anew. The conceptual models presented by the CHP team are considered to have great potential for guiding health and social policy and for implementing various health promotion practices in the community.

In our department, we use Jinnaka's Rehabilitation method as a means of aftertreatment of patients who underwent surgery to repair fresh Achilles tendon ruptures. In this paper, we compared the results of tendon ruptures in farmers with those in other occupational workers, who visited our hospital for surgical treatment from April 1990 to December 1996. The data required in this study were collected by interviewing each patient by telephone.
We repaired 22 tendons in farmers, another 22 tendons in manual, laborers, and 36 tendons in non-manual laborers (office workers, 32 tendons and housewives, 4 tendons.) The average period of follow-up was 4 years and 3 months. Re-rupture was observed in only one of the non-manual laborers. The average age of the farmer group was 50.4 years, which was higher than those of the other two groups-43.0 years for the manual laborer group, and 38.4 years for the non-manual laborer group. 83.3% of the patients in the non-mnual laborer group could return to engaging in sports. However, a smaller number of patients, 50.4%, look part in sports in either the farmer group or the manual laborer group respectively.
This low rate of comeback to sports in the farmer group may reflect their belief that physical exercise is unnecessary in light of the farmer's life style.
There are some reports that claim that farmers should engage in some kinds of sport, repeatedly and at regular intervals, to promote and maintain their health, because physical activity in farming is not necessarily sufficient or appropriate from the view point of health preservation.
It is good to promote the idea that farmers, who perform physical labor, should also take part in some kind of sport.

We have checked into the function of konjak, or the devil's-tongue (Hydrosme vivieri) to reduce cholesterol in order to cast light on its significance as a health food. We processed chipped glucomannan into crackers (hereinafter referred to as “mannan crackers”) and examined its impacts on lipid metabolism. Enrolled for this study were hospital staff members whose total cholesterol exceeded 200mg/dl and students boarding in the hospital's nursing college.
The findings attested to the fact that the intake of mannan crackers may serve to reduce the values of total cholesterol. The higher the value of total cholesterol before this study, the greater the drop. Since we could not detect any effect on either HDLcholesterol or triglyceride, the mannan crackers were considered capable of specifically reducing LDL-cholesterol. We observed no numerical changes in the complete blood cell count (CBCC) and blood chemistry, either. Some of the subjects had abdominal swelling, diarrhea and other digestive problems but theirs were not serious cases. Yet in another aspect, there was no difference in body weight between before and after this study, but the intake of energy and lipid dropped during the period, suggesting that the intake of mannan crackers would produce an effect on the dietary pattern. Having said that, konjak (mannan crackers) may be considered capable of directly or indirectly reducing cholesterol, particularly LDL-cholesterol, suggesting that mannan crackers are of significance as a health food.
The significance of this study for agriculture and rural community must not go unmarked. This study will contribute to the development of agriculture as an industry, while the farm product by the name of konjak has something to do for health, and will be instrumental in protecting the rural environment, not to mention the lives of farm workers engaged in its production. It is a task for us to grapple with by associating itself with farm work and rural villages with the close collaboration of those farm producers.

Before the introduction of high density barium for contrast studies of the upper gastrointestinal tract, we conducted a survey concerning the adverse reactions to a swallow of barium and barium concentration.
The incidence of side effects rose as the density of barium increased but the effects were transient. There were no cases requiring medical treatment.
Furthermore, the constipation group and the normal group were examined separately.
The ratio of adverse reactions was high in the constipation group even when the barium density was low. In this group stool hardening and delayed excertion were also noticed.
The constancy of barium stool excretion was basically normal, and the barium density had little effect.
The effects of a laxative on the excretion consistency were investigated. The administration of a laxative did not always have a positive affect on excretion. The timing of the administration of the laxative and the amount of water intake should be examined in the future.
We also investigated how the patients feel when they are swallowing barium. We found that whether feel uncomfortable or not depended on the properties of barium rather than its density.
From these results it appears that appropriate guidance is necessary about the use of high density barium, in order to supress the occurrence of side effects, especially in the constipation group.

Dialysis hypotension is one of the most common complications observed during hemodialysis. As it may be due to vasodilatation, vasoconstrictors are usually given to patients to control blood pressure. Howerver, there are some patients who are resistant to the medication with vasoconstrictors. Recently, it has been reported that as one of the treatments of dialysis hypotension, the cooling of dialysate is effective in inducing vasoconstriction via stimulating the sympathetic nerve system. Also, the application of the interaction of citrus juices with some kinds of drugs to the treatment of dialysis hypotension has been reported effective. In the present study, we examined the effectiveness of those two methods in nine hemodialysis patients in whom dialysis hypotension had not been improved with vasoconstrictors. Dialysate temperatures were lowered from 36.0 to 35.0 C during hemodialysis and/or 100m1 of citrus juice (grapefruit juice) were given to the patients before hemodialysis in addition to vasoconstrictors. Lowering dialysate temperaturse reduced the incidence of intradialytic hypotension and helped improve the patients' quality of life after hemodialysis therapy. Body temperature remained unchanged between before and after hemodialysis. However, we observed cramps in two patients and an impairment of consciousness in one patient during hemodialysis. Thus, we concluded due caution should be exercise against the side effects during hemodialysis when dialysate temperatures are lowered. Meanwhile, the intake of grapefruit juice before hemodialysis was not effective for the improvement of intradialytic hypotension and the patients' quality of life.

Since 1993, our hospital has been entrusted by the Gifu Prefectural Government with the operation of the home health care system in the region. Hospital healthnurses, keeping in close contact with other medical institutions and self-goverinig bodies, have endeavored to support the health and medical care of home patients.
Initially, there was much to be desired in the way some government offices were addressing to home health care and care coordination for patients when they were discharged from hospital. These inadequacies have largely been corrected and in 1998 a comprehensive home care system came into being.
Our effort to restructure the home care system has been crowned with success in many ways. Formerly there were many cases in which individual organizations rendered services separately, but now hospitals, local medical associations and government offices have come to play on the team, which has made it possible to provide home care effectively and efficiently. Moreover, the hospital staff have become fully aware of the importance of home care.

In Japan, the number of people 65 and over is increasing while the number of children is decreasing. A greater number of senior citizens live by themselves or husband and wife alone than before.
To realize comfortable and independent life for aged people, it is important to prepare housing and environment which have special services for them.
We would like to explain two housing projects which were planned and are being put into execution in Japan. One is ‘Silver Housing’ multiunit dwellings for the aged built by the Ministry of Construction and the Ministry of Health and Welfare since 1987. The other is ‘Silver Peer’ project which has been pushed forward by the Tokyo Metropolitan Government since 1987.
