Dry sand specimens for both normally consolidated and overconsolidated triaxial compression tests were prestressed on the path with five different coefficients of earth pressure 1.0, 3/4, 0.55, $K_0$ and 1/3. Deformation resistance of normally consolidated sand increased with increasing the initial stress for all coefficients of earth pressure during consolidation, and the deformation modulus at a certain initial stress showed a tendency to increase with increasing the coefficient of earth pressure. And deformation moduli($E_i$, $E_{50}$), were found to be proportional to the $n_{th}$ power of initial stresses[${\sigma}_{m0}{^{\prime}}$, ${\sigma}_{10}{^{\prime}}$, ${\sigma}_{30}{^{\prime}}$, $({\sigma}_1-{\sigma}_3)_0$] for both isotropically and anisotropically normally consolidated samples, where n varied from 0.37 to 0.92. Overconsolidated sand with the higher overconsolidation ratio showed the higher deformation modulus. It is concluded that the $K_0$-anisotropically consolidated triaxial compression test is necessary to obtain the more accurate value of in-situ deformation modulus.

The wave and hydrologic climate at a beach location are everchanging and coastal engineers have always been interested in the deformation of the natural beach caused by wave action over short or long interval of time. The drift of sand on a beach particulary manifests itself when blocked construction of seawalls, jetties, breakerwaters and groins etc.${\cdots}$ For this reason, the understanding and evaluation of littoral drift has been especially important to the coastal engineers. The resulting of the sand drift movement, such as the type of beach profile, width of beach, storage volume of the littoral sand over the profile are rapid everchange. We have studied the geological changes due to the littoral drift on a beach with field investigation and model tests in laboratory. But, it is impossible to make quantative correct analysis because of the factors are everchange and complicate. And then, most of study are incline to qualitative analysis. In this paper, authors studied mainly on the transition of beach profile and sediment storage on the profile using statistical field data as qualitative analytical method. The used theoretical beach transition model by Sonu and Beek have developed to obtain the change of HAEUNDAE beach backed with seawall. Results of this study indicate that the transition model are useful in the analysis of beach profile changement and the littoral drift movement on the beach. Qualitative analysises for HAEUNDAE beach are as follows. 1) Transition sequence of profile has 4 major transition for one cycle. 2) Storage sediment model of beach profile by Sonu and Beek well coincided with HAEUNDAE beach. 3) Seasonal cycle has ill-balanced process for the 5-yr. investigation.

This experiment was conducted to study the relationship between the energy value and the nitrogen content in the rat urine. Thirteen rats for ad libitum feeding group and 16 rats for two-meal group were employed in this experiment. The experimental period consisted of 22 days with a preliminary period of 10 days. During the last eight days of the experiment the urine was collected quantitatively. The rats fed two-meal per day excreted significantly (p<0.005) more nitrogen and energy in the urine than those fed ad libitum. A linear relationship between the energy concentration and nitrogen content was found. The urinary energy value was increased as the urinary nitrogen content was increased. A prediction equation was derived to compute the energy value from the content of nitrogen as follows: Y=8.924X+0.182 $S_{y{\cdot}x}=0.788$ where Y=urinary energy(kcal/100 ml) X=urinary nitrogen(gm/100 ml) Since the standard deviation of estimate is in small magnitude (0.788 kcal) when it is compared with the amount of intake of gross energy, digestible energy or metabolizable energy, this equation can be used safely to estimate the energy value from nitrogen content. Consequently, considerable amound of time and labor for the actual determination of energy can be saved. The ratio of energy to nitrogen was found to be 9.4 for ad adlibitum group and 8.6 for two-meal group. No significant difference between two group in this respect was observed.

This article looks at the thought of Oh Jae-soon's seonggong sasangin Jeongjo period while focusing on his Seonggongdo and Seonggong doseol. his thought will be explained as seen below. First, he gave more emphasis on seonggong, not seonghak, which is a concept abbreviated from Seonginjihak.He actually gave more importance to practice than to scholarly work. Therefore, the essential concepts provided in his work are most related with drills and practices. Second, he focuses on dotong(characters). Looking at Yosunwoosangjeonsimhakdo, he presents dotong ((Yo-Sun-Woo)-Kongtzu-Chengtsu-Jasa-Mengtsu-Chungtzu), while presenting himself to such a scholarly inheritance. Third, he intended to provide his interpretation based on his consistent thought. He actually classified and analyzed all the characters and classics based on the principles of knowledge, practice, self-esteem, bitter words, diligence. In addition, all things are classified with these five items as shown above. Fourth, he analyzed classics and presented his ideas in simple terms and concepts. Fifth, he deals with the seven Chinese Classics and particularly he emphasizes Shizing and Shujing. He did not mention Chunqiu (the Spring and Autumn Annals) and Liji (The classic of Rites),both of which he did not consider as adequate. Sixth, Sunam's thought was inherited to Ganjae Jeonwoo's soonamhakgyeol.

Adsorption experiments were carried out with several clay minerals and PCP hexane solution in order to clarify the status of adsorbed PCP on the clay surface. The amount of PCP adsorption on clay minerals was much greater in the clay-hexane system than in the clay water system. Among the clay minerals, allophane and imogolite ($SiO_2/Al_2O_3$ ratio of about 1) were the most efficient adsorbents of PCP. The PCP adsorption from hexane solution was greatly hindered by the presence of water, suggesting the occurrence of adsorption by a dipole-dipole interaction. PCP adsorption is dependent upon the nature of the clay surface and the exchangeable cations rather than the total surface area.

"난경(難經)"의 오유혈(五兪穴) 이론(理論)이 가장 많이 제기되는 문제는 '육십팔난(六十八難)'의 오유혈(五兪穴)의 주치작용(主治作用)이다. "영추 본수편(靈樞 本輸篇)"에서는 다만 오유혈(五兪穴)의 명칭과 위치에 대해서 소개하고 있지, 계통적인 주치에 대한 설명이 없고, '육십팔난(六十八難)'에서 명확히 5가지 종류의 질병에 대해서 귀납(歸納)하고 오유혈(五兪穴)이 주관하는 병증(病證)을 분별하여 후세의 모범이 되고 있다. 그러나 "난경(難經)"에서 오유혈(五兪穴)에 대해서 물이 흐르는 형상을 비유하여 사지(四肢)에서 체간(體幹)으로 향하는 노선으로 설명하고 있는데, 이는 "내경(內經)"의 십이경맥(十二經脈)이 여환무단(如環無端)하는 체계와 전혀 부합하지 않아서 학문과 임상에 있어서 지금까지도 혼란을 야기하고 있다. 그동안 "갑골문자(甲骨文字)"를 해독하기 위한 심도 있고 다양한 연구가 진행된 결과 고문자(古文字)의 해독(解讀)잘못된 계산식을 위한 공구서(工具書)들이 많이 개발되었는데, 본 논문은 그러한 고문자(古文字) 해독(解讀)의 연구방법(硏究方法)을 통해 "난경(難經)"의 오유혈(五兪穴) 이론(理論)의 난제(難題)를 해결하고자 한 것이다. 예를 들어 정형수경합(井滎輸經合)에 대해서 "난경(難經)"의 '육십팔난(六十八難)'에서 "소출위정(所出爲井), 소류위형(所流爲滎), 소주위유(所注爲兪), 소행위경(所行爲經), 소입위합(所入位合)"이라고 설명한 그 것 중에서 출(出), 류(流), 주(注), 행(行), 입(入)과 정(井), 형(滎), 유(兪), 경(經), 합(合)의 글자를 고문자(古文字) 해독(解讀)의 측면에서 재해석함으로써 이를 의학적(醫學的)으로 활용할 수 있도록 그 실마리를 제공하였다.

A study was made to investigate the effect of L-lysine fortification on the quality of rice protein by albino rat-feeding trials. Five subjects fed diets providing 1) rice protein only, 2) rice protein+0.25% L-lysin HCI, 3) rice protein+0.5% L-lysin HCI, 4) rice protein+0.75% L-lysin HCI and 5) rice protein+1.0% L-lysin HCI for 28 days respectively. Protein efficiency ratio(PER) indicated that 0.25% lysine fortified diet had highest value. Lower PER values were shown in the higher fortified diets(0.5% through 1.0% L-lysine) comparing to 0.25% fortified diet. However, there was no adverse effect on the protein quality by the given fortificaton level($0{\sim}1.0%$ L-lysin HCI addition).

This experiment was carried out to investigate the change in protein of pasteurized whole egg with or without added 1% of sugar during fermentation S. lactis, L. casei and S. faecalis were used in this fermentation test. Whole egg showed no phenomenen of coagulation by heating at $58^{\circ}C$ for 30 min, but the patterns in polyacrylamide gel of pasteurized whole egg without sugar added were changed by fermentation, especially in the egg fermented with L. casei. Polyacrylamide gel electrophoretic patterns of pasteurized whole egg added 1% of sugar changed more significantly by fermentation than pasteurized whole egg without sugar added and the most significant change was observed in the bands of conalbumin, preconalbumin, globulin and postalbumin by S. faecalis.

The development of eggs and larvae, and minute tubercles on the skin surface of the larvae in Acheilognathus lanceolatus (=Acheilognathus intermedia intermedia) from Korea were observed. The ripe eggs of A. lanceolatus from Korea were nearly spindly. The shape was distinguishable from that of Japan. And then the embryonic development of this specimen from Korea was faster than that from Japan. As regards larval development and morphology and distribution of the minute tubercles, however, A. lanceolatus in both Korea and Japan were same except for the mentioned above two characters. These findings suggested that the two formes should be separated at subspecies level.
