The purpose of this paper look at the basis of the cultural differences of Korea and Japan by comparing the view about the death. Firstly, in terms of language to express the death, Korea can be summarized 'doragada (go back) Japan can be summarized sayonara(goodbye). Koreans' view about the death is that life and death are not separated and death is the start of another life not the end of existence through 'doragada' Japanese accept death as the order of the universe and the order of nature with resignation. At this time resignation means that Japanese accept the sad feeling to sublimate aesthetically while mourning the death Secondly The view about the death of Sunbee in the Joseon era and Japanese Samurai who were the traditional ideal figures is compared. The Sunbee dies from a justification and the Samurai die from the honor on the other hand. Unconditionally, the sunbee was not loyal to an individual but they thought significantly of the fidelity about the joint value. Unlike this, Japanese Samurai laid stress on the loyalty toward their lord and sacrifice. They selected the death conclusively when this fidelity was suspected. Thirdly the view about the death of Korea and Japan is summarized to the aesthetics of the survival and the aesthetics of the death. Korean saw the death negatively and regard exceedingly the extension of life, they preceded to survive in all kinds of difficulties. On the contrary, Japanese see it positively. They beautified the death and sublimated with the aesthetics. they pursue the nature of the life through the death. Finally, the basic difference of the korean and Japanese culture originate from the view about the death that is, the difference of the values about the life and death.

태양열을 냉방에 이용하기 위한 시스템은 집열기,열교환기,냉동기 등으로 구성된다. 집열기는 난 방시와 마찬가지로 볼 때 냉난방을 병용하는 집열기를 사용하면 유리하다. 열교환기는 집열기에 서 수집한 열을 냉방기에 전달시키는 기능을 가지는데 용도에 따라 이것을 사용하지 않는 경우도 있다. 냉동기로는 보통 흡수식 냉동기를 사요하나 그외 개방식, 분사식 등의 냉동기도 사용된다. 그러나 분방식 냉동기는 취급은 용이하나 흡수제의 재생조건이 까다로워 높은 습기를 갖는 경우 재생온도가 역시 높아져야 하므로 우리나라의 경우에는 여름철의 습도가 높기 때문에 재생온도가 높아져야 하므로 태양열 냉방에는 부적당하다. 또 분사식 냉동기의 경우 성적계수(Coefficient of Performance) 가 다른 냉동기에 비해 낮고 증기압력이 낮으면 이것이 극히 낮아지기 때문에 태양 열 냉방에 많이 사용하지 않는다. 그래서 태양열 냉방에 있어서 냉동기는 거의 흡수식을 사용하 고 있으며, 여기에서도 주로 흡수식 냉동기를 사용한 냉방에 대하여 논하고져 한다.

A series of experiment was conducted to investigate the effects of the level of dietary Protein (soybean meal) and carbohydrate (sucrose) on the growth rate, feed efficiency, nutrients digestibility and amylase activity of larvae at 5th instar. The results obtained from the experimentation are summarized as follow： (1) It was found that the body weight gain, cocoon quality and feed efficiency of the 5th instar larvae were significantly affected by the level of protein and carbohydrate in the artificial diet. Present data revealed that the proper level of dietary protein and carbohydrate would be the most important factor for the optimum growth of larvae. (2) In the amount of diet consumption, the group of larvae gained more body weight consumed more diet than the group gained less amount of body weight. (3) Digestibility of nutrients was improved as the level of protein in the diet increased, although the level of dietary carbohydrate did not exert any positive results. (4) It was observed that the amylase activity in digestive juice was stimulated by the increasement of dietary carbohydrate. However, no correlation between the level of dietary protein and carbohydrate was detected in the amylase activity. (5) Analytical data indicated that the amount of protein or carbohydrate excreted through feces and urine was proportional to the content of protein or carbohydrate in artificial diet. The group o( larvae consumed the diet contained high protein excreted more protein and less nitrogen free extract than did the group received low protein diet. Likewise, the group of larvae fed high dietary carbohydrate excreted more nitrogen free extract and less protein through excreta than the group consumed low carbohydrate diet group. (6) Although the amylase activity of the larvae received the artificial diet was higher than the larvae received natural diet (mulberry leaf), the rate of body weight gam and the quality of cocoon produced from the natural diet group was better than the artificial diet group. It is, thus, concluded that feeding the larvae by the artificial diet may net be recommendable. (7) It was determined that the best level of protein (soybean meal) and carbohydrate (sucrose) in artificial diet was found to be 40g and 0g, respectively when it was fed to the 5th instar larvae. (8) It may be concluded from the results obtained that the artificial diet that could stimulate the activity of amylase nay not be recommendable for the practical larvae feeding Purpose due simply to the Poor economic return from this diet than natural diet.

The important results which have been obtained in the investigation can be recapitulated as follows. 1. As demonstrated by the experimental results and analyses concerning their effects in the on-ground type mushroom house, the constructions in relation to the side wall and ceiling of the experimental house showed a sufficient heat insulation on effect to protect insides of the house from outside climatic conditions. 2. As the effect on the solar type experimental mushroom house which was constructed in a half basement has been shown by the experimental results and analyses, it has been proved to be effective for making use of solar heat. However there were found two problems to be improved for putting solar house to practical use in the farm mushroom growing: (1) the construction of the roof and ceiling should be the same as for the on ground type house, and (2) the solar heat generating system should be reconstructed properly. 3. Among several ventilation systems which have been studied in the experiments, the underground earthen pipe and ceiling ventilation, and vertical side wall and ceiling ventilation systems have been proved to be most effective for natural ventilation. 4. The experimental results have shown that ventilation systems such as the vertical side wall and underground ventilation systems are suitable to put to practical use as natural ventilation systems for farm mushroom house. These ventilation systems can remarkably improve the temperature of fresh air which is introduced into the house by heat transfers within the ventilation passages, so as to approach to the desired temperature of the house without any cooling or heating operation. For example, if it is assuming that X is the outside temperature and Y is the amount of temperature adjustment made by the influence of the ventilation system, the relationships that exist between X and Y can be expressed by the following regression lines. Underground iron pipe ventilation system. Y=0.9X-12.8 Underground earthen pipe ventilation system. Y=0.96X-15.11 Vertical side wall ventilation system. Y=0.94X-17.57 5. The experimental results have 8hown that the relationships existing between the admitted and expelled air and the $CO_2$ concentration can be described with experimental regression lines or an exponent equation as follows: 5.1 If it is assumed that X is an air speed cm/sec. and Y is an expelled air speed in cm/sec. in a natural ventilation system, since the Y is a function of the X, the relationships that exist between X and Y can be expressed by the regression lines shown below: 5.2 If it IS assumed that X is an admitted volume of air in $m^3$/hr. and Y is an expelled volume of air in $m^3$/hr. in a natural ventilation system, since the Y is a function of the X, the relationships that exist between X and Y can be expressed by the regression lines shown below. 5.3 If it is assumed that expelled air speed in emisec. and replacement air speed in cm/sec. at the bed surface in a natural ventilation system are shown as X and Y. respectively, since the Y is a function of the X. the relationships that exist between X and Y can be expressed by the following regression line: GE(100%)-CV (50%) ventilation system. Y=-0.54X+0.84 5.4 If it is assumed that the replacement air speed in cm/sec. at the bed surface is shown as X, and $CO_2$ concentration which is expressed by multiplying 1000 times the actual value of $CO_2$ % is shown as Y, in a natural ventilation system, since the Y is a function of the X, the relationships that exist between X and Y can be expressed by the following regression line: GE(100%)-CV(50%) ventilation system. Y=114.53-6.42X 5.5 If it is assumed that the expelled volume of air is shown as X and the $CO_2$ concencration which is expressed by multiplying 1000 times the actual of $CO_2$% is shown as Y in a natural ventilation system, since the Y is a function of the X, the relationships that exist between X and Y can be expressed by the following exponent equation: GE(100%)-CV(50%) ventilation system. Y=$127.18{\times}1.0093^{-x}$ 5.6 The experimental results have shown that the ratios of the cross sectional area of the GE and CV vent to the total cubic capacity of the house, required for providing an adequate amount of air in a natural ventilation system, can be estimated as follows: GE(admitting vent of the underground ventilation) 0.3-0.5% (controllable) CV(expelling vent of the ceiling ventilation) 0.8-1.0% (controllable) 6. Among several heating devices which were studied in the experiments, the hot-water boilor which wasmodified to be fitted both as hot-water boiler and as a pressureless steam-water was found most suitable for farm mushroom growing.
