The Purpose of this study is that self-growth program searches effect self-concept and peer-relationship with elementary school student, and advance following assumption to achieve this purpose and achieved study. First, self-concept point of experiment group students who execute self-growth program will be improved is meaning than self-concept point of control group students. Second, peer-relationship point of experiment group students who execute self-growth program will be improved is meaning than peer-relationship point of control group students. Third, effect that self-growth program gets to self-concept may be meaning difference according to sex. Fourth, difference that impact that self-growth program gets in peer- relationship is meaning according to sex may join. Chose fifth-year student 2 class 68 people (experiment group n=34, control group n=34) in I primary school locating to Jeonrabuk-do Iksan-si to verify above construction for study target. Disposal about experiment group executed over 10th for 60-80 minute 2 times in a week because investigator uses reconstructing self-growth program with virtue research paper such as learning program for own growth of Lee-Hyeong-Deuk (1998). In order to verify the effect after experiment, 1 collected materials for estimation by providing the subject children with questionaires about self-concept and peer-relationship before and after the experiment, and then analyzed the average differences in number of marks between the experiment group and the control group before and after the experiment through and by using One-Way ANOVA, and SPSS 11.0 program. The following is the result what I obtained from the above study. First, there was significant difference is between average difference before and after of experiment group and control group which execute self-growth program in self-concept elevation ($F_{(1,66)} =28.734$, p <.001). From the sub-variable, there was significant difference in academic self ($F_{(1,66)}=6.423$, p<.05), Social Self ($F_{(1,66)}=48.331$, p<.001), Physical Self ($F_{(1,66)}=11.074$, p <.01), sentimental self ($F_{(1,66)}=9.402$, p <.01) Second, there was significant difference is average difference before and after of experiment group and control group which execute self-growth program in peer-relationship promotion ($F_{(1,66)}=24.109$, p <.001). From the sub-variable there W3S Significant difference in trust ($F_{(1,66)}=14.507$, p<.001), respect ($F_{(1,66)}=15.271$, p <.001). Third, there was expose that significant difference does not exist in average self-concept before and after by sex of experiment group which executes self-growth program, and was not shown significant difference in sub-vairable. Fourth, there was expose that significant difference of whole peer- relationship and in respect of sub-variable in average peer-relationship before-after by sex of experiment group which execute self-growth program, but significant difference did not appear in trust. Could get conclusion that self-growth program is effect in elementary school student self-concept elevation and peer-relationship promotion according to these study finding, and confirmed possibility that self-growth program may contribute to change emotional special quality of children positively in education spot.

The heading date is known to be controlled by two kinds of genetic constituent, photosensitivity and basic vegetable phase. For the latter, the effect of temperature in early growth period is critical to determine the shortness of vegetative growth periods in plant's life. A phytotron experiment on 55 rice cultivars, consisting of two ecotypes of rices, indica and japonica, was conducted at high and low temperature treatments at early growth stage to investigate the possible role of plant growth stimulus by high temperature to associate with shortening of heading date. The high temperature during the early growth stage stimulated the rice growth as measured by plant height with much difference of the growth response between indica and japonica. The conclusive finding that these growth stimulus in early growth stage was highly correlated with the acceleration of heading is, more or less, correlated with the heading of the late growth stage although we could not conclude the genes for early plant growth stimulus by high temperature is the same genes as the genes for accelerating of heading in the late growth stage of plants.

[ $\bigcirc$ ] In the growth simulation without changing of module with ORYZA2000, dry matter, LAI and leaf nitrogen content(FNLV) were estimated well under high nitrogen applicated condition, but overestimated under low nitrogen applicated condition. $\bigcirc$ Nitrogen stress factor on the SLA was introduced into ORYZA2000 because especially overestimated LAI under low nitrogen applicated condition was originated from SLA decrease with leaf nitrogen(FNLV) decrease. $\bigcirc$ In the growth simulation with modified SLA modified module, LAI was estimated well under even low nitrogen applicated condition, but dry matter was hardly changed compared with default. $\bigcirc$ Simulated plant nitrogen content and dry matter have no clear difference between modules, but compared with observed values, panicle weight(WSO) and rough rice yield(WRR14) were overestimated under high nitrogen applicated because of lodging, pest, disease and low nitrogen use efficiency.

Growth characteristics and changes of pigment content of purple sweet potato (PSP) during growth were investigated. Vine length of PSP was increased to the maximum length of 130 cm after 100 days of growth. Numbers of branches and nodes were increased to the maximum of 21and 550, respectively, after 120 days of growth. Vine weight was also increased to the maximum of 4,384 kg/10a after 120 days of growth, while the weight of marketable root was increased continuously to the end of the growth period of 150 days to reach the production of 1,875 kg/10a. Uniquely considerable amount of anthocyanin pigment has been developed in both skin and flesh of young roots harvested after 40 days of growth. The pigment content was increased slowly until 140 days of growth then decreased. This fact indicates that the best time for harvesting of PSP is 140 days after planting.

This study was conducted to find out environment conditions in order to increase of growth and yield of tuberlets in pinellia ternata (Thunb.) Breit. The optimal temperature conditions for the growth of tuberlets were good rather temperature fluctuations than constant one and the optimal photoperiod was a 6hr-photoperiod. The growth of tuberlets to the kinds and concentration of growth regulators was good for 0. lppm 2.4- D, 10ppm kinetin and 50ppm gibberellin treatment. In colchicine soaking treatment, the growth of tuberlets was bad, but bulblets formation was good for 0. 05% colchicine treatment for 48hr. -soaking. In colchicine dropping treatment, dry tuber yield was good for 0. 1% colchicine treatment with once dropping for one day.

Pot experiment was conducted to find out the effect of decomposing degree of rice straw on growth characteristics of flue-cured tobacco, NC82. Tobacco growth was hindered by fresh straw of rice application. Generally, it was known that if organic matter of high Carbon/Nitrogen ratio had applied in soil, there was temporary nitrogen deficiency in plant caused by soil microorganism utilized nitrogen contained organic matter. In pot experiment, it was supposed that tobacco growth hindered by fresh straw of rice application was not nitrogen deficiency by soil microorganism, but gas toxicity by fresh straw of rice application.
