  • 리더십에 관한 연구는 리더십 특성요인연구, 리더십 contingency 연구, 특성이론적 접근, 행동적 접근, 상황이론적 접근 등이 있으나, 이러한 접근방법이 언제나 긍정적인 리더십을 유발하는 것은 아닌 것으로 나타나고 있다. 따라서, 긍정적이고 일관된 리더십을 만들어 내기 위해서는 리더십에 대한 새로운 접근이 요청된다. 리더십에 대한 연구는 매우 다양하게 나타나고 있으나, 문헌연구에서 볼 때 리더십은 파워라는 공통 요소를 가지고 있다. 파워는 사람으로 하여금 목적지향적인 행동을 유발하는 능력이며, 문헌에 나타난 리더십의 개념은 조직구성원으로 하여금 목적지향적인 행동을 하게하는 능력이다. 따라서, 리더십은 권력의 한 유형으로 볼 수 있다. 그러므로, 본 연구에서는 리더십을 power process에 기초한 권력순환적 관점에서 연구하고자 한다. Power process는 권력요소, 가치, 욕구, 환경, 관계의 다섯 가지 권력결정요소들의 상호작용 과정이다. 이러한 상호작용을 통해서 power process는 권력의 원천을 창출하는데 이 원천에 의한 권력행사는 긍정적인 결과를 유발한다(이경환, 2001). 앞에서 지적한 바와 같이 리더십은 권력의 한 유형이므로, power process에 의한 리더십 행사를 실증연구를 함으로서 지식경영시스템 구축을 위한 요인을 제시하고자 한다. 본 실증적 연구에서 리더는 자신의 권력요소(타고난 능력, 소질, 경험 등=경영자특성)와 욕구, 가치(경영철학) 관계성 및 환경과 같은 파워결정요소(리더십 결정요소)의 상호작용을 통해 자신의 리더십 원천을 창출할 때 즉, power process를 통해 리더십을 행사할 때 이러한 리더십은 경영성과에 긍정적인 결과를 유발하는 것으로 나타났다. 그러므로, 리더십 성과 향상을 위한 지식경영정보시스템은 파워결정요소적 측면에서 고려되어야 할 것이다. 모델과 독립성 모델에서는 시스템 등급에 영향을 준다. 향후에는 더욱 더 다양한 상호의존 모델들이 정량화될 필요성이 있다고 본다. 진행하였다. 줄여서 보다 더 정확하고, 지능적인 규칙구성요소 추출 방법론을 제시하고 구현하여 지식관리자의 규칙습득에 대한 부담을 줄여 주고자 한다. 도움을 받을 수 있게 되었다.을 거치도록 되어있다. 교통주제도는 국가의 교통정책결정과 관련분야의 기초자료로서 다양하게 활용되고 있으며, 특히 ITS 노드/링크 기본지도로 활용되는 등 교통 분야의 중요한 지리정보로서 구축되고 있다..20{\pm}0.37L$, 72시간에 $1.33{\pm}0.33L$로 유의한 차이를 보였으므로(F=6.153, P=0.004), 술 후 폐환기능 회복에 효과가 있다. 4) 실험군과 대조군의 수술 후 노력성 폐활량은 수술 후 72시간에서 실험군이 $1.90{\pm}0.61L$, 대조군이 $1.51{\pm}0.38L$로 유의한 차이를 보였다(t=2.620, P=0.013). 5) 실험군과 대조군의 수술 후 일초 노력성 호기량은 수술 후 24시간에서 $1.33{\pm}0.56L,\;1.00{\ge}0.28L$로 유의한 차이를 보였고(t=2.530, P=0.017), 술 후 72시간에서 $1.72{\pm}0.65L,\;1.33{\pm}0.3L$로 유의한 차이를 보였다(t=2.540, P=0.016). 6) 대상자의 술 후 폐환기능에 영향을 미치는 요인은 성별로 나타났다. 이에 따른 폐환기능의 차이를 보면, 실험군의 술 후 노력성 폐활량이 48시간에 남자($1.78{\pm}0.61L$)가 여자($1.27{\pm}0.45L$)보다 더 높게 나타났으며 (t=2.170, P=0.042),

  • The application of the Life Cycle Impact Assessment (LCIA) methodology to analyze the environmental burden of appling the digestates to corn field including different swine waste treatment systems was investigated. The first part of LCA is an inventory of parameters used to emissions released due to the system under investigation. In the following step, the Life Cycle Impact Assessment, the inventory data were analyzed and aggregated in order to finally get one index representing the each environmental burden. Each corn field applied with the aerobic and anaerobic digestates including different swine waste treatment systems was used as an example for the life cycle impact analysis. With analyzing the agricultural environmental burden, it observed that the effect of corn field applied aerobic digestate including digestion system was 7.6 times higher at eutrophication effects, but global warming potential effect was 0.9 times less than its applied anaerobic digestate.

  • This study applied aquatic and land-based exercises to breast cancer patients for comparative analysis and elucidation of their effects on the rehabilitation of cancer patients. Participants included 40 breast cancer patients who were divided into two groups: 20 participants in the experimental group using aquatic exercise and 20 participants in the control group using land-based exercise. After the addition of aquatic or land-based exercises five times per week for eight weeks, differences in each group's shoulder and pulmonary functions as well as their quality of life were compared and analyzed. The results showed a statistically significant difference (p<.001) for shoulder dysfunction, with the experimental group showing a greater improvement than the comparison group. Statistically significant differences (p<.05 and p<.001, respectively) were also observed for forced vital capacity (FVC) and forced expiratory volume in one second (FEV1), with the experimental group showing greater improvements. Finally, a statistically significant difference (p<.001) was observed for change in the quality of life, with greater improvements in the experimental group than in the control group. The results of further research in this field are expected to indicate the most efficient method for the recovery and management of physical, psychological, and social health impacts of breast cancer on patients. Furthermore, the research aims to provide fundamental resources for breast cancer rehabilitation in South Korea by conducting studies on patients with lung cancer or colorectal cancer and the application of various aquatic exercise methods.

  • This study was attempted to identify the health-related quality of life of Chronic Obstructive Pulmonary Disease (COPD) patients and factors influencing the quality of life, focusing on Health-related quality of life with 8 items (HINT-8). The subjects of this study were 451 adults aged 40 years or older who performed lung function tests and whose ratio is less than 0.7 by measuring forced respiratory volume in 1 second [FEV1] to forced vital capacity in the 2019 National Health and Nutrition Examination Survey, It was analyzed using SAS program. As a result, both the HINT-8 index and EuroQol five-dimensions 3-level version (EQ-5D-3L) index were appropriate as tools to measure the health-related quality of life in COPD patients, and the factors affecting the health-related quality of life were age, gender, income, and smoking status, comorbidities, stress, and subjective health status. Therefore, in order to improve the health-related quality of life of COPD patients, an individualized management program suitable for the characteristics of subjects such as the low-income class and the elderly, including smoking cessation education and stress management, should be developed and applied.

  • Disposal of high amount of coal combustion by-products, such as fly ash and bottom ash, is of a great concern to the country, due to the huge treatment cost and land requirement. On the other hand, those coal-ash wastes are considered to have desirable characteristics that may improve physical, chemical, and biological properties of soils. Especially, compared with fly ash, bottom ash has a larger particle size, porous surface area, and usable amount of micronutrients. In the present study, we examined bottom as a soil amendment for mitigating $CO_2$ emission and enhancing carbon sequestration in soils fertilized with organic matter (hairy vetch, green barely, and oil cake fertilizer). Through laboratory incubation, $CO_2$ released from the soil was quantitatively and periodically monitored with an enforced-aeration and high-temperature respirometer. We observed that amendment of bottom ash led to a marked reduction in $CO_2$ emission rate and cumulative amount of $CO_2$ released, which was generally proportional to the amount of bottom ash applied. We also found that the temporal patterns of $CO_2$ emission and C sequestration effects were partially dependent on the relative of proportion labile carbon and C/N ratio of the organic matter. Our results strongly suggest that amendment of bottom ash has potential benefits for fixing labile carbon as more stable soil organic matter, unless the bottom ash contains toxic levels of heavy metals or other contaminants.

  • In this study, various influent sludge pre-treatment methods and the internal recirculation of thickened sludge from effluents using a liquid/solid separation unit were adopted to investigate their effects on the sludge digestion and methane production in a combined mesophilic anaerobic and thermophilic aerobic sludge digestion process. A lab-scale combined sludge digestion process was operated during 5 phases using different feed sludge pre-treatment strategies. In phase 1, the feed sludge was pre-treated with a thermal-alkaline method. In contrast, in phases 2, 3 and 4, the internal recirculation of thickened sludge from the effluent and thermal-alkaline, thermal, and alkaline pre-treatment (7 days) were applied to the combined process. In phase 5, the raw sludge without any pre-treatment was used to the combined process. With the feed sludge pre-treatment and internal recirculation, the experimental results indicated that the volatile suspended solid (VSS) removal was drastically increased from phases 1 to 4. Also, the methane production rate with the thermal-alkaline pre-treatment and internal recirculation was significantly improved, showing an increment to 285 mL/L/day in phase 2. Meanwhile, the VSS removal and methane production in phase 5 were greatly decreased when the raw sludge without any pre-treatment was applied to the combined process. Considering all together, it was concluded that the combined process with the thickened sludge recirculation and thermal-alkaline pre-treatment can be successfully employed for the highly efficient sewage sludge reduction and methane gas production.

  • For examination, amaranth was first dried its surface after sufficient soaking in water. Dried amaranth was roasted when the moisture contents reached 30∼50%, its nasty smell disappeared and its color turned to yellow and it was puffed. Pretreated amaranth was added to biscuit for the improvement of apparence and merchandise value. The maximum expansion was reported at the moisture percentage of 130∼160% according to the examination of expansion and moisture percentage. In order to compare gelatinization of different processing, three different amaranth were prepared as follows ; Raw amaranth, steamed/dried amaranth, and roasted amaranth. The degree of gelatinization was increased as the percentage of moisture was increased and the degree of gelatinization of roasted amaranth was higher than the one of steamed/dried amaranth, their moisture contents were 62.10% and 57.59%, respectively In addition, the hardness($\times$10$\^$5/dyn/㎠) of roasted amaranth was showed lower values than that of steamed amaranth and raw amaranth were showed the large values. After examining biscuits containing each amaranth, raw amaranth had problem with nasty smell and bad texture, and streamed/dried amaranth were able to remove viscosity but turned brown. Biscuits containing roasted amaranth had good smell and texture, and besides the color of biscuits became bright because roasted amaranth turned white. Biscuits tasted best when it contained 5% of roasted amaranth. The rancidity of biscuits with 5% roasted amaranth were proceeded slowly while roasted amaranth itself had high acid value and peroxide value. For the safety from oxidation, it was fairly safe for about 6 months.

  • Background : Patients with locally advanced non-small cell lung cancer are often treated with radiation alone or in combination with chemotherapy. Both modalities have a potentially damaging effect on pulmonary function. In order to examine changes in the cardiopulmonary exercise function of patients with locally advanced non-small cell lung cancer before and after conventional radiotherapy, we conducted a prospective study involving patients with such cancer, that had received radiation therapy. Method : Resting pulmonary function test, thoracic radiographic finding and cardiopulmonary exercise test(CPET) were assessed prior to and 4 weeks following radiation therapy in 11 male patients with locally advanced non-small cell lung cancer. Patient with endobronchial mass were excluded. Results : The forces vital capacity (FVC), forced expiratory volume in 1 second ($FEV_1$ and maximal voluntary ventilation (MVV) did not decreased between before and 4 weeks after radiation but the diffusing capacity (DLCO) had decreased by 11% 4 weeks after radiation, which was not statistically significant. No changes in maximal oxygen consumption ($VO_2$max), carbon dioxide production ($VCO_2$), exercise time and work load were attributed to radiation therapy. Follow up cardiopulmonary exercise testing revealed unchanged cardiovascular function, ventilatory function and gas exchange. No difference in cardiopulmonary exercise test performance was observed between pre- and post-radiation. Conclusion : Cardiopulmonary exercise function did not decrease within the short-term after the radiation of patients with locally advanced non-small cell lung cancer.
