Background: With the recent rapid industrialization, occupational safety and health (OSH) has become an important issue in all industrial and human activities. However, incidents of injuries and fatality rates in the Ghanaian industry sector continue to increase. Despite this increase, there is no evidence regarding the element of OSH management in transport activities in Ghanaian industries. Thus, this study aims to examine the perceptions regarding the importance of safety and health in work-related transport activities in Ghanaian industries. Methods: A survey data collection technique was used to gather information on best safety practices over a 5-month period. We randomly selected 298 respondents from industries to answer structured questionnaires. The respondents included drivers, transport managers, and safety engineers. Standard multiple regression model and Pearson product-movement correlation were used to performed the analysis. Results: The result shows that for interventions to improve safety and health, concentration has been on drivers' safety practice with less attention to safe driving environments and vehicle usage. Additionally, the respondents are aware of the importance of OSH in transport activities, but the level of integration does not measure up to the standard to reduce operational accidents and injuries. Finally, strong commitment to changing unsafe practices at all levels of operations appears to be the effective way to improve safety situations. Conclusion: OSH culture is not fully complied in industries transport activities. This study, therefore, supports the use of safety seminars and training sessions for industry workers responsible for transport operations for better integration of safety standards.

목적 : 본 연구에서는 노인들의 신체적 활동을 일 관련 신체활동, 운동 및 여가 신체활동, 이동 관련 신체활동, 앉아서 하는 활동으로 나누어 신체적 활동 유형 별 참여 여부가 노인들의 건강 관련 삶의 질과 정신건강에 어떤 관계가 있는지 알아보았다. 연구방법 : 본 연구는 2016년에 수행된 제7기 1차년도 국민건강영양조사(The 7^th Korea National Health and Nutrition Examination Survey KNHANES VII-1)에서 건강 설문조사에 응한 65세 이상 978명을 대상으로 수행되었다. 신체활동유형, 건강관련 삶의 질(EQ-5D), 우울지수(PHQ-9), 스트레스 인지수준, 수면시간 등의 관계성을 복합표본설계선형회귀분석으로 알아보았다. 결과 : 신체활동은 건강 관련 삶의 질과 정신건강에 있어, 강도 높은 일이나 가사활동에 참여할 경우는 부정적인, 중강도 이상의 여가에 참여하는 경우 긍정적인 영향을 주고 있음을 알 수 있었다. 앉아서 하는 활동의 시간이 많을수록 건강 관련 삶의 질에 부정적 영향을 준다는 다른 연구 결과와는 다르게 노인들의 앉아서 하는 활동은 건강 관련 삶의 질과 정신건강에 긍정적 영향을 주었다. 결론 : 연구 결과, 우리나라 노인은 여가 관련 신체활동과 앉아서 하는 활동은 건강 관련 삶의 질에 긍정적이며, 일과 관련된 신체활동은 삶의 질을 낮추는 부정적 요인으로 작용한 것으로 해석할 수 있었다. 이러한 국내 노인들을 대상으로 한 신체활동의 수준과 건강 관련 결과를 바탕으로 노인 대상의 의미·목적있는 작업중심 활동 프로그램을 수립할 때 참고하도록 해야 할 것이다.

When plants are exposed to subfreezing temperatures ice crystals are forming within extracelluar space in leaves. The growth of ice crystal is closely related to the degree of freezing injury. It was shown that an antifreeze protein binds to an ice nucleator through hydrogen bonds to prevent growth of ice crystal and also reduces freezing damage. The antifreeze proteins in plants are similar to PR proteins but only the PR proteins induced upon cold acclimation were shown to have dual functions in antifreezing as well as antifungal activities. Three of the genes encoded for CLP, GLP, and TLP were isolated from barley and Kentucky bluegrass based on amino acid sequence revealed after purification and low temperature-inducibility as shown in analysis of the protein. The deduced amino acid of the genes cloned showed a signal for secretion into extracellular space where the antifreezing activity sup-posed to work. The western analysis using the antisera raised against the antifreeze proteins showed a positive correlation between the amount of the protein and the level of freeze tolerance among different cultivars of barely. Besides it was revealed that TLP is responsible for a freeze tolerance induced by a treatment of trinexapac ethyl in Kentucky bluegrass. Analysis of an overwintering wild rice, Oryza rufipogon also showed that an acquisition of freeze tolerance relied on accumulation of the protein similar to CLP. The more direct evidence for the role of CLP in freeze tolerance was made with the analysis of the transgenic tobacco showing extracellular accumulation of CLP and enhanced freeze tolerance measured by amount of ion leakage and rate of photosynthetic electron transport upon freezing. These antifreeze proteins genes will be good candidates for transformation into crops such as lettuce and strawberry to develop into the new crops capable of freeze-storage and such as rose and grape to enhance a freeze tolerance for a safe survival during winter.
