Heart rate is a relatively simple and non-invasive method that is used as an important physiological indicator in many studies and has a close relationship with heart structure and function, cardiovascular disease and sudden cardiac death. In general, appropriately low heart rate during resting means effective heart function and cardiovascular fitness; heart rate at recovery is an important indicator of health and disease condition. We found a beagle dog (Dog_1) with a high heart rate in the previous preliminary experiment. Therefore, purpose of this study was to compare the heart rate response of the Dog_1 with the control group during 12 weeks of interval exercise, to evaluate the structural and functional abnormalities of the heart and to verify the applicability of exercise program. Heart rate was checked during 12 weeks of interval exercise, and after the exercise was over, imaging examination and hematological and serum biochemistry were performed. As a result, Dog_1 (165.6 ± 1.5) showed significantly higher heart rate in low intensity session of interval exercise than control group (133.3 ± 0.5, p < 0.01). In addition, Dog_1 (181.2 ± 1.4) showed significantly higher heart rate than control group (155.1 ± 0.9) in high intensity session (p < 0.01). The heart rate (30 sec, 60 sec) during recovery state was higher in Dog_1 (30 sec: 156.8 ± 4.0, 60 sec: 166.8 ± 5.8) than in the control group (30 sec: 111.2 ± 2.5, 60 sec: 104.0 ± 5.1, p < 0.01). The results of the imaging examination of Dog_1 with high heart rate confirmed that the heart had no functional and structural abnormalities. All beagles with the interval exercise program did not show maladjustment, and in the hematological and serum biochemistry results, all the parameter were within the reference range. If the interval exercise program of this study is used in the future, it is expected to be used as an important basic data to achieve the purpose of health, welfare, and physical fitness improvement of dogs.
In this study, SM45C-STKM13B hollow shaft of different thickness was joined by friction welding. After friction welding, we treated to specimen of annealing(post-weld heat treatment). The specimens were tested as-welded and post-weld heat treatment(PWHT). The mechanical properties including tensile test and vickers micro-hardness were examined. And then, the mechanical properties were compared for as-welded and PWHT in SM45C to STKM13B. Microstructure of joining part were examined in the weld interface and weld region and heat affected zone and base metal of weld parts.
The objective of this study was to address the issues associated with the solubility of the pork meat oligopeptide, while maintaining its original nutritional value and improving its digestibility. The pork meat oligopeptide was used to produce an oral liquid supplement that was contained in a 200 ㎖ can. The formulation was designed to satisfy 20% of the daily recommended nutrition intake of an adult male aged between 20 and 29. Analysis of the quality characteristics showed that this formulation was highly homogenized as an oral liquid supplement with advanced solubility. In addition, based on the viscosity, pH, color value, turbidity, and brix, the product was shown to advanced processing quality with great solubility; however, there was some concern that the taste would be deteriorated due to the bitter taste of the peptide. Thus, further studies need to be performed before this formulation can be commercialized.
본 연구는 원예활동이 결혼이주여성의 사회적 적응 및 부부관계 개선에 미치는 영향에 대해서 알아보고자 실시하였다. 원예활동은 다문화 가정의 안정과 이주여성들의 한국 문화 적응을 돕고 정신건강과 부부관계개선을 위해 이들의 고유한 문화를 존중해 줄 수 있는 프로그램을 설계하였다. 또한 원예활동을 통해 이주여성들에게 사회적 공감대를 형성하도록 하였으며 새로운 지식습득으로 자신감을 갖도록 하였다. 그리고 결과물을 부부간의 의사소통 매개체로 활용할 수 있도록 하였다. 원예활동 실시 전·후 대상자들의 사회적 회피와 불편감 척도의 조사결과 대상자들의 사회적 회피와 불편감이 원예활동을 통해 감소되어지는 것을 볼 수 있었고 부부관계의 검사 결과 유의하게 부부관계가 개선되어 지는 것을 볼 수 있었다. 이와 같이 결혼이주여성들을 대상으로 원예 프로그램을 실시한 결과, 원예활동은 이주여성들에게 긍정적인 경험을 제공하여 부부관계 개선은 물론 한국 사회 문화 적응에 효과적인 것으로 판단되었다. 앞으로 본격적인 다문화 사회로 진입하고 있는 한국 사회에서 이주여성들의 문화적 충돌을 완화시켜줄 수 있는 다양한 원예 프로그램이 개발 및 적용이 된다면 이주여성들의 문화적 균형을 통하여 진정한 동화가 이루어질 것으로 생각되었다.
