This paper attempts to explore the theory of self-cultivation(修養論) for the Unity of Heaven and Man, Mind and Nature(天人心性合一) in the Doctrine of the Mean(中庸). In the unity of heaven and Man, the meaning of the way of Heaven are doctrine of the Mean, sincerity, Nature, Sage, five ways forward, mind of the way, and the meaning of the way of man are thinking to be Cheng(誠之), secularity, the way, education, three methods of excelling, the way of man. The way of Heaven(天道) is the principle of the Universe and give the original Nature to Mankind. The way of Man(人道) is what man should do to accomplish the way of Heaven, and in that process, the unity of Heaven and Man accomplished. The unity of the mand and nature explained by the concept of mind's equilibrium-harmony. When the emotion arise rightly by rectifying mind, the mind unify with the original nature. After the unity of Heaven and Man and the unity of mind and nature, the whole world can governed by nine guidelines(九經) on the base of self-cultivation. There are several methods to get the unity of Heaven and Man and the unity of mind and nature. These are represented by the preserving mind and extending knowledge. In that methods, right timing by watchful when alone, loyalty-sympathetic understanding, selecting Goodness and holding on to it firmly, and fulfilling the mind's equilibrium-harmony

정제두는 조선시대를 대표하는 양명학자라는 평가를 받기는 하지만 구체적 학문경향에 대해서는 다양한 평가가 공존하는데 이와 같은 현상은 말년에 갈수록 양명학보다는 경세론, 예설, 경학으로 그 관심의 무게를 확대한 데에 주요한 원인이 있을 것이다. 한편 경학 연구가 반드시 양명학의 기본정신에 위배된다고는 할 수 없기 때문에 문제의 핵심은 경전 해석에 적용된 관점에 대한 평가가 중요하게 된다. 그의 중용설을 분석해 보았을 때 정제두는 인간을 포함한 만물의 보편적 존재를 규명한 책으로서 "중용"을 이해하기 보다는 인간수양서로서 "중용"을 이해하고 있었다. 이는 그가 경학 연구에서도 도덕실천을 중시한 양명학적 입장에 서 있었음을 잘 보여준다.

The present study was conducted to know the growth and yield of in response to the drought stress at the different soybean growth stage. Drought stress was given to the soybean plants on early vegetative growth at fourth-node stage(FNS), mid-growth at beginning pod stage(BPS) and late growth at beginning seed stage(BSS) for 30 days, which are high availability in soil water stress on climate condition of Korea. Dry weight was decreased severely by water stress at FNS, and BPS and BSS has no difference compared to control. Chlorophyll content of leaf severely decreased at the end of water stress of FNS and BPS, but was recovered at the harvest stage. Drought-stressed root distributed mainly near the soil surface and number and dry weight of root nodule were decreased severely by drought stress at BPS. Number of pod, seed weight and yield were decreased by drought stress and showed the highest yield loss at BPS.

Effect of over flooding moisture levels on the growth and yield of barley and wheat crops was determined. The marked plant height retardation of barley under over saturated moisture treatment was observed at the elongating stage and wheat at the booting stage. The elongating and tillering stage subjected to over flooding moisture level significantly reduced panicle number and grain number per panicle, and 1000-grain weight reduction at the booting stage streated with over saturated moisture level. The highest yield reduction of two row and six row barley stage, under over flooting moisture level. Soil wet resistance observed in decreasing order; wheat<six row barley<two row barley.

Removal of apical ear after silking is a method to increase seed production in corn inbreds. Due to the phenomenon of apical dominance, the subapical ear would develope and produce seeds following the removal of the apical ear. This experiment was conducted to investigate the varietal difference in subapical ear development and seed production. Days to silking of subapical ears were delayed by about 4 days compared to normal apical ears. Cob length and filled ear length of subapical ears across seven inbreds tested were reduced by 21% and 36%, respectively. Those of inbred INV302 decreased less and subapical ear of inbred NC246 were barren, which incicated the varietal defferences. Number of kernel rows, kernels per row, and total kernels per ear also decreased. The mean reduction rates for those characters were 28%, 37%, and 47%, respectively. Weights of ears and kernels were reduced and showed different response among inbred lines. Coefficients of variations for cob and filled ear lengths, number of kernel rows and kernels were greater in subapical ears than in apical ears. Seed production of subapical ears was 40 ~ 80% of apical ears, depending on inbred lines when the apical ear is removed immediately after silking.

This study assessed the manner in which social activities, religious experiences, and spiritual practices related to depression and life satisfaction among 217 Korean elderly individuals, aged 65 to 80. The Social Activities Scale and Brief Multidimensional Measure of Religiosity/Spirituality were employed to assess social activities and six domains of religiosity/spirituality: daily spiritual experiences, values, forgiveness, private religious practice, religious/spiritual coping, and religious support. In addition, depression was assessed with the Geriatric Depression Scale, and life satisfaction with the Satisfaction with Life Scale. After controlling for demographic variables, lower depression scores were predicted by higher levels of religious and spiritual coping, social activities, higher income, and ower daily spiritual experiences. In addition, identifying as female, advanced old age, and lower social activities predicted lower life satisfaction in this study. The implications of this study's findings on social work practice are also discussed, along with some future research directions.

This experiment was conducted for the production of alismatis rhizoma (Alisma plan­tago-aquatica var. orientale Samuelsson) with high root tuber yield and alisol-B monoacetate content by treatment of different fertilizers levels. The results obtained were as follows: Shoot growth tended to in­crease as the fertilizers levels increased. Root tuber yield increased by 25% and 20% with 20-10-20 and 30-15-30 treatment, respectively. Alisol-B monoacetate contents increased as fertilizers levels increased, being the highest in 30-15-30 treatment.

This study was to compare year variations of heritability, phenotypic, genotypic and environmental correlations as well as pathway coefficients for main characters of tea tree to provide useful selection information for improving tea tree. The data collected from the performance yield trials from 1979 to 1981 were used in this study. I. The genetic variance of fresh fruit yielding, dryed fruit yielding and fresh weight of root was not only greatly varied with year, but also the largest among all characteristies studied. Other characteristics showed higher genetic variance than environmental variances, and year variances were not large. 2. Both year and variety x year interaction were highly significant sources of variation for all yield characteristics, and year variances were not large. 3. All characteristics showed high broad sense heritabilities, and the broad sense heritability was not varied with year. 4. The genetic correlation coefficients between fresh fruit yielding and dryed fruit yielding, fresh weight of root and Gigolpi, dryed weight of root and Gigolpi were positive, and the year variation was not large. S. The pathway coefficients of the character was not only greatly varied with year and the fresh weight of root affected directly on the Gigolpi.
