  • 일본에서는 학생들의 심각한 학력 저하 문제를 해결하기 위한 논의가 활발하게 전개되고 있다. 초.중.고등학교의 교육과정에 해당하는 새로운 '학습지도요령'이 올 연말에 발표될 예정이다. 과학교육을 중심으로 지금까지 일본에서 논의되어 왔던 내용과 앞으로의 개혁 방향에 대해 살펴본다.

  • The purpose of this study was to examine the effect of neuromuscular electrical stimulation(LFES) during hindlimb suspension on weight and function of rat hindlimb muscles. Sprague-Dawley rats(body weight 300-350g) were randomly assigned to five groups: a HLS(n=5) that were hindlimb suspended for 14 days, a WB(n=5) that kept as control, a ES14 that were hind limb suspended for 14days with pre-application of LFES for 14 days, ES11 that were hindlimb suspended for 14 days with pre-application of LFES for 11 days, a LFES 7 that were hindlimb suspended for 14 days with pre-application of LFES for 7 days. Gastrocnemius muscle weight, stride length were significantly decreased and toe out angle were significantly increased in HLS and ES7 groups, whereas muscle weight, stride length, toe out angle were maintained in ES14, ES11. this indicated that LFES for 14 days, LFES for 11 days could prevent muscle atrophy and retain function.

  • This study was conducted to develop a index for the judgment of suitability of storage conditions by internal gas concentration of 'Fuji' apples under CA storage, and was examined the relationship between the levels of quality characteristics(flesh firmness, titratable acidity and surface green color) and the infernal ethylene and carbon dioxide concentrations of apples. The levels of quality characteristics were not decreased for terms of storage when the infernal ethylene concentration of apples was below 10 ppm, but the levels of quality characteristics were sharply decreased when it was above 10 ppm of Internal ethylene. The high levels of quality characteristics were maintained by the lower internal carbon dioxide concentration of apples, especially at below 2% of internal carbon dioxide. These result showed that the suitable condition for CA storage of 'Fuji' apples was a condition for having below 10 ppm of internal ethylene and below 2% of internal carbon dioxide in apples. The internal ethylene and carbon dioxide concentrations of apples during CA storage can be used as a crucial index for the suitability judgment of storage conditions.

Effects of Tree-spray of Calcium Formate Compound Extracted from Oyster Shell and Active Agent on the Calcium Concentration, Fruit Skin Shape, and Quality of 'Fuji' Apple Fruit (굴 껍데기에서 개미산으로 추출한 칼슘화합물과 활성제의 수관살포가 사과 '후지' 과실의 칼슘농도, 과피 형태 및 품질에 미치는 영향)

  • This study was carried out to investigate the effects of tree-spray of calcium formate compound extracted from oyster shell with several active agents on the calcium concentration, fruit skin shape and quality of 'Fuji' apple. The tree-spray of calcium formate compound extracted from oyster shell (Os-CaF, $52.4\;mg{\cdot}kg^{-1}$) appeared to have more effectiveness on the calcium translocation into leaves, fruit skin and flesh than control. Addition of adjuvants to Os-CaF increased calcium concentration of 'Fuji' apple when sprayed three times before harvest. Among the active agents examined, the treatment ascorbic acid and poly-vinyl alcohol (PVA) in leaves, Ag-colloidal and PVA in fruit skin, ascorbic acid, Ag-colloidal, and PVA in fruit flesh exhibited highest effectiveness. Fruit qualities (fruit weight, firmness, soluble solids, acidity and Hunter value) were not affect by Os-CaF on different concentrations and solutions of active agents.

  • A 5-year-old intact male black gibbon (Hylobates concolor) was referred for evaluation of the right pelvic limb lameness following a fight against other black gibbons. Fractures of the right tibia and fibula were suspected on physical examination and palpation of the right pelvic limb, but no other injuries or abnormalities were detected. While the black gibbon was sedated, pelvic limb radiographs were taken, which revealed diaphyseal oblique fractures of the right tibia and fibula. Open reduction of the fractures was performed. The tibial fracture was repaired by use of an internal fixation technique that included a tubular dynamic compression plate and cortical screws secured along the craniomedial aspect of the tibia. There were no complications during the postoperative rehabilitation period. At 9 weeks, radiographs revealed that bridging callus was well formed over the cortices of the tibial and fibular fracture area. The cast was removed 9 weeks after surgery. The black gibbon exhibited no evidence of lameness and was released back into the group. Presently, there are no published reports of internal fracture fixation in a black gibbon where a tubular dynamic compression plate and cortical screws provided excellent stabilization of the tibia and complete fracture healing allowing normal ambulation.

  • We investigated the effects of both $CaCl_2$ treatment and modified atmosphere packaging (MAP) (compared with non-packaging on 'Fuji' apples from the Young-Joo region of Korea. Apples were dined into 5% (w/v) $CaCl_2$ solution for 15 min and then packaged with or without LDPE film (thickness: 0.025 mm) before cold storage at $0^{\circ}C$. Weight loss of applies in film packaging was lower than that of non-packaging applies, and the apple firmness resulting from $CaCl_2$ treatment and MAP was better than that of apples receiving control treatment. Also, $CaCl_2$ treatment and MAP resulted in improvements in titratable acidity, soluble solid content (SSC), and decay rate compared to control treatments. However, no significant differences in vitamin C content were found amongst apples receiving various treatment. the results suggest that a combination of postharvest calcium dipping and plastic film packaging may effectively preserve 'Fuji' apples, and that the combined treatment are better than either individual treatment.
