The purposes of this study were to determine the actual state of indoor environments of solitary elderly houses in the rural district during winter and to analyze the relationship between the influencing factors and indoor physical elements. Field surveys consisted of measurements of physical elements, observations of living factors, and resident's responses in interviews. Field surveys were carried out in 4 houses from $28^{th}$ of February to $2^{nd}$ of March 2008. The elements measured were air temperature, relative humidity, floor temperature, seating-place temperature, CO2 concentration, CO concentration, and illumination. The results showed that the average indoor temperature for houses was $13.5{\sim}22.5^{\circ}C$, relative humidity was 30.6~55.4%, floor temperature was $13.9{\sim}24.0^{\circ}C$, temperature when seated was $27.6{\sim}51.1^{\circ}C$, $CO_2$ concentration was 1434.6~3305.5 ppm, CO concentration was 2.8~8.4 ppm, and illumination was 31.0~96.7 lux. The residents' clothing values were 1.10~1.78 clo. The environment was evaluated as being in an unsuitable state, and it was revealed that the main reason was the lack of heating and ventilation.

Fish is an extremely perishable food product which requires proper handling soon after harvest. The present study was aimed at assessing post-harvest fish losses and preservation practices in Siavonga district, Southern Zambia. Structured and semi-structured questionnaires were used to collect data on post-harvest fish losses and preservation practices from aquaculture producers, artisanal, and commercial fishers. All the fishers who landed on the lakeshore were interviewed, while aquaculture producers were randomly selected based on the information provided by the local department of fisheries. The results of the study revealed that all the fishers experienced post-harvest fish losses at varying degrees with those losing up to 10% of the total catch being in the majority. In contrast, aquaculture producers did not report any post-harvest fish losses. Most aquaculture producers commonly used chilling as preservation practice contrary to artisanal and commercial fishers who commonly used smoking and sun sun-drying respectively. Furthermore, fish product safety and quality control were poorly practiced in the district. Lack of cold storage facilities and fluctuating weather conditions were the major challenges impacting fish post-harvest activities. Therefore, to curb the loss of revenue due to post-harvest fish losses, we propose the introduction of new technology, self-development skills for fishing communities, and enhanced access to refrigeration facilities.

We arrive at the conclusion as follows as for the connection between dietary life, hours of exercise and growth of body, based on the survey of their height, this circumference of the breast and their body weight, and the questionnaires to the pupils of 36,547 in totals (contained the primary and middle school boys and girls) in four districts(named A, B, C and D district) of Jeonlla Bug Do from April, 1970 to March, 1973. (1) The growth in height. The boys from 6 to 7 years old are nearly same in all districts, but as age increases, those of A district grow more rapidly than those of B, C and D districts, while those of B, C and D districts grow almost samely. The girls already from 6 years old on are different between A district and B, C, D district. The average of height in Jeonlla Bug Do is not different from that of Gyungi Do and whole nation in the pupils from 6 to 11 years old, and that of Japan from 6 to 7 of age, while it falls behind them as age increases. (2) The growth in the circumference of the breast. The boys from 6 to 9 years old show nearly the same tendency in all districts, after that age the boys in A district tend to grow rapidly, those in B district most fall behind, and those in C, D districts show the same tendency. Contrasted with height the growth in the circumference of the breast does not show the difference in each district so far as 14 of age, but after 15 years old it shows a little difference by falling behind of pupils in A district, while those B, C, D districts show almost the same tendency. The average of the circumference of the breast in Jeonlla Bug Do of the pupils from 10 to 11 of age is almost same to that of Gyungi Do, whole nation and Japan, but shows difference after that age. (3) The growth of body weight. The body weight of boys over-all the investigated whole age shows the superiority in A district and a little lowness in D district which is almost same to that of B, C districts. In that of girls, A district is superior in from 6 to 9 of age, and all districts are nearly same after that age. The average in Jeonlla Bug Do is one and the same to those of Gyungi Do, whole nation and Japan as in the height, but shows the great difference as years grow. (4) The dietary life of the pupils in Jeonlla Bug Do depends chiefly upon a carbohydrate and is very low in the intake of fat and protein. Connected with a view point of districts, the intake of protein is a little more in A district than in the other districts, and is nearly same in the other districts. They tend more to eat mixed food, but about 40% of them do not yet eat it. The contents and taking of lunch is bad in the highest degree, to which their parents are entirely indifferent. As far as the hours of exercise are concerned with, about 40% of all pupils must go to the school from very far, which gives them the heavy physical suffering, and especially it is remarked that the middle school boys and girls should attend school from farther than the primary school boys and girls.
