The seed spray technology prepares for landscape by spraying seeds, fertilizers and other materials but does not consider the relationship of the germination time and temperature of seeds for construction. The purpose of this study is to develop a functional formula that shows the relationship of germination and temperature for using the Papaver orientale L. seeds for the spray technology. The germination test in a chamber was progressed from March to April 2014 and the verification experiment proceeded in a greenhouse in May 2014. After culturing each 100 seeds of Petri dish and Papaver orientale L. seeds on filter beds 4 repetitive times, each 10mL of the first distilled water was sprayed to treat temperature at level 7 and the light source was maintained at 4~4.5μmoles/m²/s. The germination rate was investigated at two-day intervals, and the germination was based on the emergence of 3mm radicles. For experimental verification, seeding was implemented in a greenhouse and daily mean temperatures and germination periods were investigated. As a result of the treatment, based on a 50% germination rate, the functional relation between the temperature and germination period was found to be y = 1/-0.0004x²+ 0.0224x-0.0398, R2 = 0.9441. As the result of the analysis of the cardinal temperature from using graphs of functions, the lowest temperature was 2°C and the optimum temperature was 28°C and the highest temperature was 54°C, but in the actual test, normal germination was made at 5°C and the unusual germination of the final germination rate was below 50% at 35°C. In the experimental verification, as a result of substituting the daily mean temperature with functional formulas, it was found to be 4.4 days and the lapse of time for actual foliation was investigated to be 5.5 days.

의료환경에서 환자의 생채정보를 효율적으로 전송하기 위해 실시간으로 수집한 정보를 통해 응급환자의 정보를 신속하고 정확하게 전달하고, 주기적인 의료데이터와 비주기적인 CE응용 데이터의 전송 시 전송지연을 최소로 할 수 있어야 한다. 본 논문에서는 IEEE 802.15.4를 통해 긴급데이터만을 신속하게 처리 할 수 있는 EP구간을 설정하고, 주기적인 데이터만을 보낼 수 있는 CFP 구간과 비주기적인 데이터를 받아 경쟁하여 보내는 순서정보를 통해 Inactive구간을 활성화시켜 스케줄링 방식으로 데이터를 보내주어 다양한 데이터들이 신속하고 정확하게 전송지연 없이 보낼 수 있도록 한다. In order to transmit bio-data of patient efficiently under medical environment, information of emergency patient is required to be transmitted rapidly and correctly through information being collected in real time and transmission delay should be minimized at the time of transmitting regular medical data and irregular CE application data. In this study, diversified data was designed to be rapidly and correctly transmitted in a scheduling mode without trransmision delay in a way of activating Inactive section through order information of transmitting data under contention access including CFP data section that may send regular data only and irregular data section after setting EP section in which only emergency data could be sent rapidly through IEEE 802 15.4.

A research related to a growth characteristic according to attach or not in accordance with wall materials and growth direction of 5 kinds of vine plants used in green-wall was proceed. Test was proceed from May to September 2010. Materials of wall used in the test are 6 kinds of timber, adobe, grass, brick, concrete and aluminum, and the vine plants used in the test are Euonymus radicans cv. aueonmarinata Rehd., Euonymus radicans Sieb. var. argenteo-marginatus Rehd., Campsis grandifolia (Thunb.) K. Schum., Schizophragma hydrangeoides Siebold & Zucc., Hedera rhombea (Miq.) Bean. Growth of the vine plants is high in a sequence of Campsis grandifolia (Thunb.) K. Schum., Hedera rhombea (Miq.) Bean, Euonymus radicans cv. aueonmarinata Rehd., Euonymus radicans Sieb. var. argenteo-marginatus Rehd., Schizophragma hydrangeoides Siebold & Zucc., and sheath rate of the vine plants is high in a sequenc of Campsis grandifolia (Thunb.) K. Schum., Euonymus radicans cv. aueonmarinata Rehd., Hedera rhombea (Miq.) Bean, Euonymus radicans Sieb. var. argenteo-marginatus Rehd., Schizophragma hydrangeoides Siebold & Zucc. However, Euonymus radicans Sieb. var. argenteo-marginatus Rehd., Schizophragma hydrangeoides Siebold & Zucc., Hedera rhombea (Miq.) Bean, are has a lower sheath rate compared to the growth rate. Difference of the growth according to north and south directions of the vine plants is that ampsis Hedera rhombea (Miq.) Bean., is high in the south direction, Campsis grandifolia (Thunb.) K. Schum., Schizophragma hydrangeoides Siebold & Zucc. and Euonymus radicans Sieb. var. argenteo-marginatus Rehd. has high growth rate in the north direction. And Hedera rhombea (Miq.) Bean. has high growth rate in the south direction on May~July and in the north direction on August~September. Attach or not according to materials of wall is that Campsis grandifolia (Thunb.) K. Schum. can be attached to timber, adobe, brick and concrete, Euonymus radicans Sieb. var. argenteo-marginatus Rehd. can be attached to brick and adobe, and Euonymus radicans cv. aueonmarinata Rehd., Schizophragma hydrangeoides Siebold & Zucc., Hedera rhombea (Miq.) Bean., can be attached to timber. However, all vine plants can not be attached to grass and aluminum.
