This study was conducted to analyze the productivity and economic feasibility of truss-limited tomatoes (Lycopersicon esculentum L.) grown at a high density in Cambodia during the rainy season. During the rainy season in Cambodia, due to excessive rain and very high temperature, tomatoes cannot grow well in an open field, leading to a greatly reduced yield. High density truss-limited cultivation (HDTLC) of tomatoes can shorten the growing season and increase yields. In conventional cultivation (control), tomatoes were transplanted at a spacing of 70×40 cm and harvested up to the 4th fruit cluster. In HDTLC, tomatoes were transplanted at a spacing of 20×20 cm or 25×25 cm and harvested up to the 2nd fruit cluster. Plant heights in HDTLC were higher than those in the control at 22 days after transplanting (DAT). At 39 DAT, plant heights did not differ between 25×25 cm and control. At 60 DAT, plant height, stem diameter, leaf length, and leaf width of the HDTLC were lower than those of the control. Fruit length and width were also lower in HDTLC compared to those of the control. However, sugar content was more than 19% higher in HDTLC compared to that in the control. Yield per plant of the control was the highest, but yields per ha in HDTLCs were 99% (20×20 cm) and 38% (25×25 cm) higher, respectively, compared to that of the control. No pesticides were used for disease control in this experiment. However, to ensure yield, it is recommended to observe the disease status of plants and spray pesticides at the appropriate time. The disease index (1: disease-free; 5: all leaves were disease-infected) of late blight (Phytophthora indestans) was significantly higher for 20×20 cm (4.5) and 25×25 cm (3.6) groups compared to the control (2.0). Income with 20×20 cm (5,668 thousand KRW) and 25×25 cm (1,863 thousand KRW) were 4.9 and 1.6 times higher, respectively, compared to that with the control (1,149 thousand KRW). So, we want to spread the HDTLC technology, which transplanting of tomato seedlings at 20×20 cm intervals and harvests up to 2nd fruit cluster, to Cambodian farmers.

Background: Low back pain (LBP) is a representative disease, and LBP is characterized by muscle dysfunction that provides stability to the lumbar spine. This causes physical functional problems such as decreased posture control ability by reducing the muscular endurance and balance of the lumbar spine. Pelvic compression using instruments, which has been used during recent stabilization exercises, focuses on the anterior superior iliac spine of the pelvis and puts pressure on the sacroiliac joint during exercise, making the pelvis more symmetrical and stable. Currently, research has been actively conducted on the use of pelvic compression belts and non-elastic pelvic belts; however, few studies have conducted research on the application effect of pelvic compression using instruments. Objects: This study aimed to investigate whether there is a difference in trunk muscular endurance and dynamic and static balance ability levels by applying pelvic stabilization through a pelvic compression device between the LBP group and the non-LBP group. Methods: Thirty-nine subjects currently enrolled in Daejeon University were divided into 20 subjects with LBP group and 19 subjects without LBP (NLBP group), and the groups were compared with and without pelvic compression. The trunk muscular endurance test was performed with 4 movements, the dynamic balance test was performed using a Y-balance test, and the static balance test was performed using a Wii balance board. Results: There was a significant difference the LBP group and the NLBP group after pelvic compression was applied to all tests (p < 0.05). In the static and dynamic balance ability test after pelvic compression was applied, there was a significant difference in the LBP group than in the NLBP group (p < 0.05). Conclusion: These results show that pelvic compression using instruments has a positive effect on both those with and without LBP and that it has a greater impact on balance ability when applied to those with LBP.

본 연구의 목적은 아일랜드 Senior Cycle과 한국의 고등학교 수학교육과정의 학습내용요소를 비교·분석하여 한국의 학습 수준에 대한 방향설정이나 교육 내용의 전개 및 유도 방법 등 교수학습 전반에 대한 교육적 시사점을 찾는 것이다. 학습내용요소를 대수, 해석, 기하, 확률과 통계 영역으로 구분하여 영역별 학습내용요소를 비교하고 두 나라 사이의 유사점과 차이점을 비교하였으며 공통된 학습내용요소 중에서 이차방정식, 미분의 단원에 대해 내용전개 및 설명방식을 비교하였다. 이를 통해 아일랜드의 경우 보통과정과 심화과정에서 학습내용요소 및 문제의 난이도, 형식적 수준이 다르며 단원의 도입부터 본문의 학습내용요소가 체계적이며 논리적으로 구성된 한국과 달리 직관성과 도구적 의미를 강조하여 교과서를 구성하고 있음을 확인 할 수 있었다. 한국의 교과서에도 이와 같은 구성에 대한 효과 분석을 통하여 시사점을 얻는다면 교과서의 질 향상에 도움이 될 것이라는 제안점을 도출하였다.
