  • The purpose of this study was to determine the inheritance of chlorosis under low temperature at seedling stage of rice. The expression of chlorosis among 21 rice cultivars treated at $18^{\circ}C$ showed in one Tongil type cultivar, Milyang 23, and two Indica type cultivars, IR 36 and Dular. The sign of chlorosis was not appeared in all of the japonica type cultivars under the same treatment. The reduction of chlorophyll content under the low temperature was differed from varietal group and cultivars. The $F_2$ population from a cross between Toyohatamochi and Dular segregated 3:1 ratio for normal and white phenotypes of third leaf. From the result, it was suggested that the chlorosis was controlled by a single recessive gene. The chlorosis rice detected from this study will be used as a good material for the genetic study related to photosynthetic ability of rice.

  • It is essential to record maxillomandibular relationship accurately for the harmony of esthetic and function in complete denture. Gothic arch tracing visually demonstrates the movement of the mandible, and is useful to establish accurate and reproducible centric relation. Proper retention and stability of complete denture in patients with severe alveolar bone resorption is difficult to attain. In such case, the closed mouth impression technique might be recommended. The denture border and impression are determined by patient's physiologic movement in the closed mouth impression technique. And, denture peripheral border is entirely closed with oral mucous membrane. This report presents satisfactory complete denture restoration using closed mouth impression technique and gothic arch tracing in patients with mandibular condyle fracture and severe absorption of mandibular alveolar ridge.

  • The Gothic arch tracing method using a Gothic arch tracer which is one of the centric relation recording methods can reproduce mandibular movement more accurately by describing the path of mandibular curvilinear motion. This case reports that we have satisfactory results by recording reproducible centric relation using a gothic arch tracing method in a patient who has difficulty to induce centric relation by operator due to parafunctional movement.

  • 남미 Venezuela국에 있는 면적 약 $26.6\;km^2$, 수심 약 6m의 함수호인 Restinga Lagoon에서 1979년 9월, 10월 2개월간 그곳 자연산 굴인 Crassostrca rhizophorae의 채묘시험을 실시하였다. 채묘성적은 St.2(Fig.2)에서 우수하여 채묘기 $100cm^2$당 약 45개체가 발견되었는데, 부착치패는 조차범위인 약 30cm중 중간 10cm 부분에서 가장 많았고 저조선하에선 각종 부착생물이 다량 부착되었을 뿐 굴 치패는 거의 발견되지 않았다. 따라서, Restinga Lagoon에서의 채묘적지는 St.2가 적합하였고 채묘기 설치위치는 약 4시간 노출선인 저호선위 $15\~10\;cm$가 최적이었다.
