The present study was conducted to estimate average weights, and corrlation and regression coefficients among various traits of eggs obtained from Korean native and imported chicken. Data were obtained from 360 layers (180 of Korean native origin, and 180 of imported Decalb Brown) between November 8, 1994 to February 8, 1995. The results obtained are summerized as follows : 1. The mean weights of whole egg, yolk, dense white, thin white, and egg shell of native chicken were lighter (P<0.01) than those of Decalb Brown. 2. The coefficients of variability in each egg trait were lower in native chicken than in Decalb Brown, indicating the higher ability of native chicken to adapt to the local environment. 3. The phenotypic correlation coeffcients between whole egg and weights of yolk, dense white, thin white, and eggshell were 0.842∼0.992(P<0.01) in native chicken, and 0.865∼0.985(P<0.01) in Decalb Brown. 4. The average eggshell thicknesses of native and imported Decalb Brown were 362.5 $\mu\textrm{m}$ and 407.9 $\mu\textrm{m}$, respectively. 5. The regression coefficients of most of the traits of eggs from native chicken were lower than those from Decalb Brown layers, suggesting that Korean native chicken should be improved further in various egg traits measured in this study.

Mi-Am Yu hi-chun(眉巖 柳希春, 1513~1577) was one of the Honam Sarim(湖南士林) with Ha-Sue Kim In-Hoo(하서 김인후) and Go-Bong Ki Dae-Seuing(고봉 기대승) in 16C. But He was condemned to exile and spend 19 years in Jong-Sung, with enthronement of King Sun-jo, was appointed as a gyeong'yeongwan(經筵官), one of the Eulsa sarim(乙巳士林). And at that time, he publicated Jujaeoryu munjip juhae(주자어류문집주해), which is a match for Toegye(퇴계). But due to the shortage of existing work, the study of his learning was not accomplish in depth. Then this article made clear his learning with Mi-Am ilgi (미암일기), which was written for ten years before he die. But a period of yubae literature did not studied. This article present this matter and established the feature.

"관자(管子)" 사편(四篇)은 전국 말 직하황노도가(稷下黃老道家)의 문헌으로 중국철학사에 있어 매우 중요한 위치를 점하고 있다. 하지만 "관자(管子)" 사편(四篇)은 문헌과 저자에 대한 기록이 불확실하고 제자백가의 사상을 포괄적으로 수용 복잡한 사상체계를 형성하고 있기 때문에 오랜시간 사람들의 주목을 받지 못했다. 1940년대 학자들은 중국철학 사료를 다시 정리하였고 이때 곽말약(郭沫若)에 의해 "관자(管子)" 사편(四篇)의 명칭이 처음으로 등장하게 된다. 1994년 "직하황노학파적비판(稷下黃老學派的批判)"과 "송견윤문유저고"에서 곽말약(郭沫若)이 "관자(管子)" 가운데 "심술(心術)" 상하(上下), "백심(白心)", "내업(內業)"의 사편(四篇)를 송견(宋?)과 윤문(尹文)의 저작이라고 주장한 이래 고문헌의 출토와 더불어 "관자(管子)" 사편(四篇)는 다시 학계의 관심을 받기 시작한다. "관자(管子)" 사편(四篇)의 저작 시기는 전국말로 추정된다. 이 시기는 사상의 르네상스라고 불릴 만큼 많은 학자들이 저마다의 독특한 논리들로서 당시의 사회의 문제점을 직시하고 그 해결방안을 모색하였던 시대였다. 농업생산력의 향상과 교통의 발달로 많은 지식인은 제(齊)나라의 직하(稷下)에 모여 전대의 역사적, 철학적 유산을 기반으로 심(心)과 도(道)에 관한 논의를 벌였고, 그 통합적 저작물이 "관자(管子)" 사편(四篇)이다. 때문에 "관자(管子)" 사편(四篇)는 전국시대 제자학(諸子學)을 총정리하는 종합서의 성격을 가진다. 본 연구의 목적은 "관자(管子)" 사편(四篇)에 나타나는 심(心)개념의 연구를 통해 전국말 직하황노도가(稷下黃老道家)의 심(心)에 대한 이해를 살펴보는데 있다. 이를 위해 먼저, "관자(管子)" 사편(四篇)의 중심철학범주인 도(道), 기(氣), 정기(精氣)와 심(心)의 관계에 대하여 살펴보고, 다음으로 "관자(管子)" 사편(四篇)에 보이는 심(心)의 개념분석을 통하여 구체적인 심(心)의 구조와 기능에 대하여 탐색할 것이다. 그리고 마지막으로 심(心)과 그 수양론(修養論)에 대하여 검토할 것이다.

This pot experiment was conducted to find out the effects of slaked lime($L_{0}$ ; 0.00, $L_1$; 3.75, $L_2$; 7.50, $L_3$; 11.25ｇ/pot) and silicate fertilizers($S_1$; 3.75, $S_2$; 7.50, $S_3$; 11.25ｇ/pot) on the seedling growth and yield of grass/clover mired swards on newly reclaimed hilly soil, and it's differences between both the soil improvers. The results obtained are summarized as fellows: Comparing with the $L_{0}$ treatment without soil improver, the seedling vigour and yields of both forages were markedly enhanced by the application of soil improver. The positive offsets of soil improvers tended to be relative higher on ladino clover than orchardgrass in mixed swards. The seeding vigour, botanical composition, and yield of ladino clover were more markedly influenced by the application of silicate fertilizer than slaked line. The yields of ladino clover were increased 75.8% by the 51 over $L_1$, and 32.0% by the $S_2$ over $L_2$, respectively.

This pot experiment was conducted to find out the forage productivity and mineral contents in an orchardgrass sward affected by the compost, lime, and phosphorus applications on the newly reclaimed and arable pasture soils. This 3rd part was concerned with the effect of phosphorus application($P_{0}$ : control, $P_1$=1.25ｇ, $P_2$=2.50g, $P_3$=3.75g $P_2$$O_{5}$ pot). The results obtained are summarized as fellows; There were considerable differences between the newly reclaimed and arable pasture soils in the soil chemical characteristics as follows in general; poor~common in the newly reclaimed soil and common~good in the arable pasture soil in terms of soil fertility standard. Comparing with the arable pasture soil, the contents of available$ P_2$$O_{5}$ / in the newly reclaimed soil at end of experiment were considerably increased by the $P_2$$O_{5}$ applications, These effects in the newly reclaimed soil were positively influenced by the additional application of compost, but were adversely influenced by the additional application of lime. The seedling vigour and yield of orchardgrass were far better in the arable pasture soil than in the newly reclaimed soil. At the $P_{0}$ treatment, those were very poor in 也e newly reclaimed soil, but were good in the arable pasture soil. Comparing with $P_1$ treatment, the above effects of heavy $P_2$$O_{5}$ / applications($P_2$and $P_3$) were not recognized. On the newly reclaimed soil, the above effects were markedly enhanced by the applications of $P_2$$O_{5}$ with compost. The Ca, Mg, and P contents of orchardgrass were relatively higher on the arable pasture soil than on the newly reclaimed soil, whereas ere were no differences in the K contents.

This study carried out on the manufacturing of pidan. The production of pidan can be one of solutions for over-produced eggs and stable egg price. For the alkali-pickling solution for manufacturing of Pidan, the tested concentration of NaOH and NaCl were respectively as 3, 5, 7% and 5, 10, 15, 20%, and examined every 2 days for 14days. According to the results, pH value of alkali-pickling solution was increased by the increment of NaOH concentration and the pickling period, and was decreased by the increment of NaCl concentration. The pH value of egg yolk was increased by the increment of NaOH concentration, but it was not significantly different by the NaCl concentration. By the increment of NaOH and NaCl concentrations, the alkali infiltration in egg yolk and egg white was accelerated. Furthermore, the weight change of the eggs in the alkali-solution has no effects on manufacturing of Pidan. Liquefied albumen showed significant differences by NaOH concentration rather than that of NaCl. There was no liquefied albumen for 14days at 3% of NaOH, but it was found between 11-12days at 5% and 8-10days at 7%, respectively. The pH values of egg white when it was liquefied albumen were between 11.8 and 12.0. Pidan was made by heat treatment after 6-7days dipped in the solution at the concentration of 7%, about 10days at 5%, and 12-14days at 3% of NaOH, respectively. Although, the period of manufacturing of Pidan was saved by the increment of NaOH concentration, liquefied albumen was accelerated and the food preference was decreased by ammonia odor. Therefore, the suitable concentration of NaOH is between 3 and 5%, and that of NaCl is between 5 and 10% due to the effect of salinity by the soaking period. Through this study, optimal pickling solution and dipping time for manufacturing of Pidan was figured out, and also find out that it can save a time about 15days for manufacturing of Pidan.

동굴은 우리의 옛 조상들이 강 가까운 동굴 속에 살면서 바닷가나 냇가에서 물고기를 잡아먹으며 살아가는 등 먼 옛날 석기시대에는 혈거생활의 주거지로 이용되어 왔을 뿐만 아니라 그 후 인류가 발전함에 따라 다양하게 이용되어 왔다. 즉, 때로는 은신처로 이용되어 왔고 때로는 묘지로, 작전기지로, 그리고 물자의 저장고로도 이용되었고 그밖에 수양터와 신앙의 장소 등으로 사용되었었다. 이러한 증거로서 인골화석, 생활을 위해 선조들이 사용하였던 다량의 도구 등 일상용품이 아직도 보존되어 남아있는 것이 발견되고 있다. 우리 나라에서 가장 독특한 문화를 갖고 있는 제주도에서도 여러 개의 동굴이 발견되었다. 이들은 성인상으로는 모두 제주도의 화산 폭발과 관련된 것이어서 용암동굴로 분류되고 있다. 그 중에서 삼성혈은 제주도의 삼성신화, 즉 부족 형성과 관련 있는 것이고, 빌레못동굴은 구석기시대에도 재주도가 주거지로 이용되었음을 인증 받는 중요한 자료로 활용되고 있다. 또한 김녕사굴의 설화는 재주도 설화의 하나로서 제주도 정부와 주민들간의 일치단결에 대한 예를 보여주고 있으며, 산방굴은 제주도 여인들의 기개에 대한 예를 나타내 주는 곳이고, 세계에서 가장 긴 동굴군계인 만장굴은 여인의 한을 전설로 담고 있다. 이렇듯이 동굴은 인류와 매우 밀접하게 관련되어 있음을 확인할 수 있다. 따라서 이제 동굴은 그 학술적ㆍ문화적 가치로서는 물론 최근에 붐이 일고 있는 관광적 측면에서도 그 보전 및 연구ㆍ개발이 시급하다 하겠다.

The Facing Targets Sputtering(FTS) system has several advantages for preparing films over a wide range of working gas pressure on plasma-free substrates. Co-Cr thin films seem to be one of the most promising media for perpendicular magnetic recording system. In this study, the capabillities of the system fordepositing C0-Cr films have been investigated. Under various Ar gas pressure, films with morphologically dense microstructure and good c-axis orientation were deposited, even when the incident angle $\psi_x$ of sputtered part icles to the film plane was below abount $50^{\circ}C$. this may imply that the shadowing effect by obique incidence of particle can be compensated by rapid surface diffusion owing to the high kinetic energy of particles arriving at the growing film. It has been confirmed that the FTS system is very useful for perparing Co-Cr thin films recorging media.
