Purpose: The purpose of this study is to evaluate the knowledge and attitudes of oncology ward nurses toward cancer pain management and to find ways to improve the educational program for nurses. Method: A total of 209 nurses working at the oncology ward of three hospitals in Seoul and a Gyenggi Province. The survey instrument used was the 32-item scale for evaluating nurses knowledge and attitudes originally developed by McCaffery and Ferrell'(1990). that was by Kim'(1997). Result: In terms of the nurses knowledge of pain management. the result showed that the nurses scored an average of 67.8 out of 100 for phamacokinetics of opioids. 84.8 for classification of analgesics, 60.1 for pain assessment, and 70.7 for drug administration. 18.2% of the nurses hesitate to inject the narcotic agent because of concerns regarding the drug's potential side effects. there was significant difference in the knowledge of pain management according to the general characteristics of pain in terms of the nurses age(p=.001), position (p=.016). years of experiences(p=.002), experience of cancer pain education(p= .001). Conclusion: The also showed that nurses working at cancer ward lack knowledge. It is important to provide intensive education to nurses about cancer pain management.

Comparison of the Metabolic Costs of Gardening and Common Physical Activities in Children
Sin-Ae Park,A-Young Lee,Kwan-Suk Lee,Ki-Cheol Son 한국원예학회 2014 원예과학기술지 Vol.32 No.1
This study investigated the exercise intensity and energy expenditure involved in two gardening activities (planting transplants and sowing seeds in a garden plot) and four common physical activities (running, skipping rope, walking, and throwing a ball) in children. Eighteen children aged 11 to 13 years (mean age, 12.3 ± 0.7 years) participated in this study. The children made two visits to a high tunnel in Cheongju, Chungbuk, South Korea and performed randomly selected activities. Each activity was performed for 10 min, with a 5-min rest period between activities. The children wore a Cosmed K4b² (Cosmed K4b²; Cosmed, Rome, Italy), which is a portable calorimetric monitoring system, to measure indicators of metabolic cost such as oxygen uptake and energy expenditure. The children’s heart rates during the activities were measured by radiotelemetry (Polar T 31; FitMed, Kempele, Finland). We found that the two gardening and four physical activities performed by the 11-13 years old children in this study were moderateto high-intensity physical activities [i.e., 5.4 ± 0.7 to 9.1 ± 1.4 metabolic equivalents (METs)]. Running (9.1 ± 1.4 METs) and skipping rope (8.8 ± 1.1 METs) were high-intensity physical activities, whereas walking (6.1 ± 0.9 METs), planting transplants (5.8 ± 1.1 METs), throwing a ball (5.6 ± 1.1 METs), and sowing seeds (5.4 ± 0.7 METs) were moderate-intensity physical activities. Running and skipping rope were significantly more intense than the other activities (P < 0.0001). The gardening tasks such as planting transplants and sowing seeds in a garden plot showed similar exercise intensities and energy costs as walking and throwing a ball. This study indicates that gardening can be used as a physical activity intervention to provide health benefits similar to more common physical activities such as walking and running.

칼랑코에는 에틸렌에 민감한 식물로 알려져 있다. 운송환경이나 슈퍼마켓의 전시대와 같이 에틸렌이 많은 환경은 식물의 외관과 수명을 단축시킨다. 이 실험에서는 두 종류 에틸렌 억제제(STS와 1-MCP)가 온실재배된 분화 칼랑코에의 모의 수송 후 개화와 수명에 미치는 영향을 조사하였다. 두 억제제는 각각 모의 수송 전에 칼랑코에에 처리되었다(STS: 0.2, 0.5, 1mM, 1-MCP: 50, 100, 200nLㆍL?¹). 5일 동안의 모의 수송환경 처리 후 칼랑코에는 화원과 유사한 환경하에 두었다. 개화수, 화아수, 위조수를 7주 동안 매주 측정하여, 개화율과 위조율을 산출하였다. 두 억제제 모두 대조구에 비해 칼랑코에 주변의 에틸렌을 효과적으로 제거함으로써 개화수와 수명을 연장시켜 분화 칼랑코에 품질을 크게 향상시켰다. 여러 처리 중 STS 0.5mM과 1mM이 개화와 수명 연장에 가장 효과적이었다. 1-MCP의 경우 STS만큼 효과적이지는 못했지만, 대조구에 비해서 확연히 개화율을 향상시켰다. 따라서 이 실험을 통해서 분화 칼랑코에 식물에 대한 이 두가지 에틸렌 억제제의 실용 가능성을 확인할 수 있었다. Ethylene sensitivity has been shown in several studies as a problem in kalanchoe. An ethylenecontaminated environment such as transportation or display stands in supermarkets deteriorates visual appearance and display life. In this study we determined the efficacy of two ethylene inhibitors, silver thiosulfate (STS) and 1-methylcyclopropene (1-MCP), on flower opening and lifespan of Kalanchoe blossfeldiana ‘New Alter’ cultivated in a greenhouse after simulated transport. STS and 1-MCP were applied to kalanchoe plants at similar commercial maturity prior to simulated transport (dark, 12℃ and 60% relative humidity). STS (0.2 mM, 0.5 mM, and 1 mM) was sprayed and 1-MCP (50 nLㆍL?¹, 100 nLㆍL?¹, and 200 nLㆍL?¹) was injected into sealed glass chambers containing kalanchoe plants for 6 hours. After simulated export for 5 days, the plants were immediately moved to a simulated retail room. The number of inflorescence, buds, and dead florets on all inflorescence were counted weekly for 7 weeks. Percentages of open flowers and dead florets were then calculated. Both STS and 1-MCP had significant effects on improving the quality of kalanchoe flowers by inducing flower opening or extending lifespan compared to the control, suggesting the inhibition of ethylene production by these inhibitors. Among the treatments, 0.5 mM and 1 mM STS showed the best results for induction of flowering and extension of lifespan. 1-MCP was not as effective as STS although the inhibitor had significantly better effects on flower opening than the control. Thus, in this study we showed great possibilities for practical usage of these two ethylene inhibitors on potted kalanchoe plants.

This study was conducted to determine the effects of silver thiosulfate (STS) and 1-methylcyclopropene (1-MCP) on flower opening and lifespan of potted Kalanchoe blossfeldiana 'Oriba' for exportation. Ethylene inhibitors, STS and 1-MCP were applied to the kalanchoe plants prior to their export to Japan. STS 0.5 mM with 1% Tween 20 surfactant was directly sprayed (20 mL per plant) to leaves, buds, and flowers and 1-MCP 100 $nL{\cdot}L^{-1}$ was injected into sealed glass chambers containing kalanchoe plants, which were placed on the chambers for 6 hours. After transport to Japan, the plants were immediately transferred to a simulated retail condition room (80 ${\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ for 12 hours of photoperiod at $22^{\circ}C$ and 64% RH) at Toyko University. The numbers of buds, open florets, and wilted florets in the middle inflorescence for each plant were counted right after export, 1 week after export, and 6 weeks after export. The percentages of open florets and wilted florets were calculated from the numbers. STS treatment resulted in 35% more open florets than the control and only 11% of wilted florets at 6 weeks after export to Japan which indicate the extension of lifespan of potted kalanchoe plants. Meanwhile, the plants exposed to 1-MCP before export did not show any significant differences in the numbers of buds and open florets and the percentages of open and wilted florets compared to control plants. In conclusion, STS 0.5 mM treatment strikingly induced better opening florets and lifespan of kalanchoe plants from 1 week to 6 weeks after export than control.

This study aimed to identify the exercise intensity associated with four common physical activities for adults (running, skipping rope, walking, and muscle strength exercises) and two horticultural activities (creating a vegetable bed and garden maintenance). For this experiment, 19 males (mean age: $25.8{\pm}2.3$ years) randomly participated in the activities at a glasshouse at Konkuk University. Each of the six activities lasted for 5 minutes; the subjects rested for 5 minutes during intervals between the activities. A portable metabolic analyzer was used to store the oxygen and energy consumption values obtained upon measurement of each activity. In addition, a wireless heart rate monitor was used to measure the subjects' heart rate. According to the results, the four types of physical activities and two horticultural activities carried out by the subjects are moderate- to high-intensity activities [i.e., $3.8{\pm}0.9$ to $9.9{\pm}2.1$ metabolic equivalents (METs)]. Running ($9.9{\pm}2.1$ METs) and skipping rope ($8.8{\pm}2.2$ METs) were categorized as high-intensity physical activities, whereas creating a vegetable bed ($5.0{\pm}1.2$ METs), walking ($4.9{\pm}0.8$ METs), muscle strength exercises ($4.5{\pm}1.3$ METs), and garden maintenance ($3.8{\pm}0.9$ METs) were classified as moderate-intensity physical activities. The exercise intensities of horticultural activities in this study were similar to those of walking and muscle strength exercises. Therefore, participating in these horticultural activities is expected to garner health benefits similar to those reaped from the physical activities described in the current study.
