This paper describes the traditional Ondol medical care, the specific combination of ancient and contemporary examples to be articulated. As a traditional Korean culture, to be extracted from the historical perspective, it described the relationship and origins between them, From a health perspective, in accordance with the logic and pharmacologyit introduced Ondol as the important principle of health care equipment. The modern architecture of some common harmful to the body, from the perspective of Ondol, it should be improved and based on scientific proof to the theory.

Effect of the ratio of mixing length to the pressure scale-height α =l/HP on the effective temperature has been investigated under some simplifying assumptions. The result is compared with that of the existing model calculations. The role of convection zone in the stellar evolution is briefly summarized.

We have investigated the structure of the general relativistic polytrope(G.R.P.) of n=5. The numerical solutions of the general relativistic Lane-Emden functions υ a n d θ for the ratio of the central pressure to the central density σ = 0.1 , 0.3, 0.5 and 0.8333 are plotted graphically. We may summarize the results as follows: 1. As the invariant radius ¯ ξ increases, the numerical value of the mass parameter υ does not approach toward the assymptotic limit, as it does in the classical case ( υ ∼ √ 3 ) , but it increases continuously with progressively smaller rate as compared with the classical case. 2. When ¯ ξ is less than ∼ 5.5 , the value of the density function θ drops more rapidly than the classical one, whereas when ¯ ξ is greater than ∼ 5.5 , θ becomes greater than the classical value. For the greater values of σ these phenomena become significant. 3. From the above results it is expected that the equilibrium mass of the G.R.P. of n=5 must be larger than the classical masse ( √ 3 ) and the mass is more dispersed than the classical configuration (i.e. equilibrium with infinite radius).

환성진화(桓星進化)의 최종단계(最終段階)에서 이루어지는 고밀도성(高密度星)(백색왜성(白色矮星), 중성자성(中性子星))의 평형(平衡)의 한계질량(限界質量)은 현재(現在)까지 태양질량(太陽質量)의 0.6 ∼ 2 배(倍)로 알려졌다. 이 값의 차이(差異)는 가정(假定)한 상태방정식(狀態方程式)에 따르고 있으나 그 어느것이나 모두 태양(太陽)의 질량(質量)과 대차(大差)없다는 사실(事實)은 주목(注目)할 일이다. 또 관측(觀測)된 보통(普通)의 별의 질량(質量)도 태양질량(太陽質量)의 1 10 ∼ 60 배(倍)의 범위에 있다. 이 두 사실(事實)을 종합(綜合)하여 태양(太陽)의 질량(質量)이 가지는 특정(特定)한 자리의 물리적(物理的)인 근거(根據)로서 Polytrope 기체(氣體)의 지수(指數) ( γ = 4 3 ) 와 ( ℏ c G m H 2 ) 3 2 의 지수(指數)사이의 연관성(聯關性)을 고찰(考察)하였다.

The spermatogenesis is the process by which spermatozoa are generated in the testes. The spermatozoa travel male reproductive tract during which they meet many substances secreted from reproductive organs. One of the substances is epididymal protease inhibitor (EPPIN) that is involved in the post-testicular maturation including capability of fertilizing the eggs. The expression of EPPIN gene was investigated in various tissues of sexually mature and regressed male Syrian hamsters by reverse transcription polymerase chain reaction (RT-PCR). The EPPIN gene was identified in the testis and epididymis of the male Syrian hamsters and compared to the genes reported previously. There was no expression of EPPIN gene in reproductively and completely regressed testes of Syrian hamster. These results suggest that the expressions of the EPPIN gene are associated with the reproductive capability in the Syrian hamsters.
