This paper reports on studies carried out regarding noise and vibration on a tractor and a binder which are the most commonly used for agricultural purposes. 1) The sound levels on both of a tractor and a binder were over 100 dBA, and the level on binder was larger about 6 dB than that on tractor. The 1/3 octave band sound pressure levels on a tractor exceeded the permissible criteria for 8 hr in the frequency range of 315 Hz and those on a binder exceeded it for 2 hr in the range of 630 Hz. 2) The vibration level on the handlebars of a tractor was the highest in the Y direction (117. 5 dB) and that under the seat was the highest in the vertical direction (97.5dB). The 1/3 octave band vibration acceleration levels for a tractor in the Y direction exceeded the exposure guideline for 4 hr in the frequency range of 16 to 50 Hz and those under the seat in the vertical direction exceeded the permissible criteria for 8 hr in the frequency range of 31.5 Hz. 3) The vibration level on the handlebars of a binder was the highest in the Z direction (114.1 dB) for the metal handlebars and (112. 1 dB) for the rubber grips. The band levels on a binder in the Z direction exceeded the guideline for 4 hr in the frequency range of 50 Hz and from 16 to 25 Hz. 4) We confirmed that there was sufficient danger of to hearing due to noise and vibration hazards in using both a tractor and a binder continuously for long periods of time in comparison with the exposure guideline and permissible criteria.

The purpose of this study is to make clear comprehensive relationship between Thymol turbidity test values (TTT) and the dietary intakes of nutrients. The subjects of this study were 287 young healthy people in Tokushima prefecture.
The results of the survey were as follows:
1) In males, multiple regression analysis showed that variables which correlated best with the TTT values were dietary intakes of sugar energy and vegetable protein aged 30-49 years, and dietary intakes of animal fat and energy aged 50-69 years.
2) In females, multiple regression analysis showed that variables which correlated best with TTT values were dietary intakes of animal protein and vegetable fat aged 50 69 years, but there were no statistically significant correlation between TTT values and the dietary intakes of nutrients aged 30-49 years.

The purpose of the present paper is to explore the relationships between the activity and fraction ratio of serum γ-GTP and the dietary intake of nutrients through three groups (lean, normal and overweight) by Broca's index. Broca's index in each groups was under 89 for the lean group, from 90to 109 for the normal group and over 110 for the overweight group. The subjects of study were 249 young healthy men except alcoholic.
Results of the survey were as follows:
1) There were statistically significant correlation between serum total γ-GTP activity in normal group and vitamin C intake (P<0.05).
2) High negative correlations were observed between the fraction ratio of serum γ-GTP (1) and the vitamin B 1 intake (P<0.01), between the fraction ratio of serum γ-GTP (1) and vitamin C intake (P<0.01), and between the fraction ratio of serum γ-GTP (1) and the protein intake/kg of body weight (P<0.01) in the lean group. High negative correlations were observed between the fraction ratio of serum γ-GTP (1) and the protein intake (P<0.01), between the fraction ratio of serum y -GTP (1) and the vitamin B 1 intake (P<0.01), between the fraction ratio of serum γ-GTP (1) and vitamin C intake (P<0.01), and between the fraction ratio of serum γ-GTP (1) and the protein intake/kg of body weight (P<0.01) in the normal group. High negative correlation was observed between the fraction ratio of serum γ-GTP (1) and the vitamin C intake (P<0.01) in the overweight group.
3) Multiple regression analysis showed that the variables which correlated best with the fraction ratio of serum γ-GTP (1) were dietary intakes of the energy, the vitamin C and the protein intake/kg of body weight in the lean group. The fraction ratio of serum γ-GTP (1) related to the vitamin C intake and the protein intake/kg of body weight in the normal group. In the overweight group, the fraction ratio of serum γ-GTP (1) related to the vitamin C intake and the animal protein intake.

This paper reports the changes in the activity and isozyme pattern of serum LDH in healthy young men given a low protein diet (0.73-0.75/kg body weight; 40-50g/day) for 21 days.
Serum total LDH activity showed no significant change in eight healthy young volunteers who received low protein diet for 21 days. However, the percentages of LDH-5 and LDH-4 increased significantly (P<0.01) from basal levels of 5.9±2.3 and 7.1±1.4 to 10.6±2.9% and 10.1±0.9%, respectively on day 14.
These results suggest that measurements of the percentages of LDH-4 and LDH-5 isozymes can be used to evaluate the protein intake, but serum LDH activity cannot be used as an index of nutrition.

The purpose of this study is to make clear a comprehensive relationship between two groups of blood properties and nutrient intakes. The first group of measurement include hemoglobin contents, hematocrits and blood specific gravity and the second group of measurements includ energy, protein, fat, carbohydorate, vitamin A, B₁, B₂, C, animal protein, animal fat, iron, animal iron and age.
These figures are taken from the epidemiological survey of Tokushima prefecture, including 301 males and 379 females, investigated from 1975 to 1980.
Appling the canonical correlation analysis, we found the following results.
1) In male, only canonical correlations were statistically significant. The hematocrit related strongly to carbohydorate, animal protein, fat intakes and age.
2) In female, only canonical correlations were statisticall significant. Both hemoglobin contents and blood specific gravity effected carbohydorate and energy intakes.

Five long-distance runners and five non-athletes were examined on lipoprotein metabolism at rest, during, and after pedaling exercise (60% of the maximal oxygen uptake) . At rest, the concentrations of the cholesterol (Cho.), triglyceride (TG), and phospholipid (PL) of very low density lipoprotein (VLDL) were kept at low level in the longdistance group compared with the non-athletes. The difference is significant (p<0.01) . On the other hand, the levels of the Cho, and PL of high density lipoprotein (HDL) were maintained high (p<0.05) . The concentrations of the TG of VLDL are in negative correlation with those of the Cho. (p<0.01) and PL (p<0.001) of HDL at rest. A positive correlation between Cho. and PL of HDL was also noted (p<0.001) . The TG of the VLDL decreased gradually with pedaling exercise in the long-distance group, reaching about 12 percent below the resting value just after exercise. However, no apparent change was noted in the non-athletes.
The results obtained indicate that the long-distance runners, compared with nonathletes, tends to use lipids in order to produce energy for exercise. There is little possibility of transferring from the Cho. and PL of VLDL to the lipoprotein during exercise for the results of no change in concentrations of the Cho. and PL of low density lipoprotein (LDL) and HDL. We concluded that the Cho, and PL of VLDL could gradually transfer to HDL by a heap of the endurance exercise for long period.

The purpose of this study is to make clear a comprehensive relationship between two groups of serum enzyme activity and nutrient intakes. The first group of measurement include serum GOT, GPT, ALP activity and the second group of measurements include protein, fat, carbohydorate, vitamin A, B1, B2, C, animal protein, animal fat, age, and weight.
These figures are taken from the epidemiological survey of Tokushima prefecture, including 252 males and 383 females, investigated from 1975 to 1980.
Appling the canonical correlation analysis, we found the following results.
1) In male, only two canonical correlations were statistically significant. The serum GOT and GPT activity related to body weight, further serum GOT activity was effected quality of food intakes.
2) In Female, three canonical correlations were statistically significant. Both serum GOT and GPT activity related to protein intakes. High correlations were observed between serum GOT activty and vitamin B1, between serum GPT activity and vitamin C, between serum ALP activity and age.

For the security of water quality in rural areas, adsorption removal of phenol which is one of disinfectants for excretions by six kinds of commercial activated carbon was investigated.
At equilibrium concentration of 1 and 10 ppm, activated carbon indicated pH 10.19 adsorbed phenol as much as 2.17 and 1.84 times compared with activated carbon indicated pH 3.06, respectively. At low equilibrium concentration of phenol, the amount adsorbed was significantly influenced by surface pH of activated carbon (p <0.05).
These results suggest that the difference in amount of phenol adsorbed onto activated carbon is due to the interaction between phenol and surface oxygen groups on the adsorbent. Therefore, it is concluded that the activated carbon of which surface is basic suitable for the adsorption removal of phenol in the agricultural waste waters.

This survey was conducted in a local city, Tokushima for its 23 administrative sections, which were classified into rural, non-rural and mixed districts based on the data related to agriculture. Complaints of public nuisances in these districts have been examined and the following findings have been obtained.
1. Complaints about water pollution and offensive odor in the rural district and those about offensive odor and noise in the mixed district have been raised more often, respectively. While, in the non-rural district more complaints about noise have been raised. Thus, it is recognized that possible pollution phenomena vary depending on regional patterns.
2. In time-serial comparison between the first half (1977-1980) and the second half (1981-1984) of survey period, it is found that total complaints of public nuisances have been reduced and the complaints in the rural district have been increased for all the types excepting dust. Therefore, it is suggested that regional environment in suburban farm villages has been deteriorating.

For the preservation of health in rural areas, this paper reports on the variation of human serum lipids by intaking lentinus edodes.
Serum lipids levels showed no significant change by intaking lentinus edodes that amounts of 20, 40 and 60g per day each for 5 days. From data of correlationship between serum lipid levels and nutrition intake of experimental diet, it was recognized that high-density-lipoprotein cholesterol level was directly proportional to carbohydrate-fat ratio significantly (p< 0.02), and was inversely proportional to fat intake, fat-protein ratio and carbohydrate-protein ratio significantly (p< 0.05), respectively. Triglycerides level was inversely proportional to protein intake significantly (p< 0.05).
These results concluded that the decrease of serum cholesterol level by intaking of lentinus edodes in healthy young men whose serum cholesterol levels were in normal range was not recognized.
