The innovation of enterprises allowed firms to promote technological innovation as an important choice to improve sustainable competitiveness. This study aims to investigate the relationship between absorptive capacity and innovation performance of Chinese high-tech enterprises and focuses on the mediating role of innovation culture in high-tech enterprises. Data came from surveying high-tech enterprises in China, and the reliability analysis, factor analysis, and correlation analysis, path analysis (SEM) were analyzed using SPSS23, AMOS. The results show that intellectual capital composed of human capital, structural capital, and relational has a significant impact on acquisition performance; intellectual capital is composed of human capital; structural capital has a significant influence on innovation performance; and absorptive capital has a significant impact on innovation performance. In addition, innovative culture plays a partial mediating role between absorptive capacity and innovation performance. The findings of this study suggest that, to ensure the better absorption and operation of knowledge, high-tech enterprises can accumulate more knowledge, promote the transformation of knowledge into technology, and strengthen the capability of knowledge absorptive capacity, and at the same time, create an innovation culture atmosphere and encourage employees to develop new products to achieve enterprise goals in order to promote the improvement of innovation performance.

[Purpose] Skeletal muscle glycogen is a determinant of endurance capacity for some athletes. Ginger is well known to possess nutritional effects, such as anti-diabetic effects. We hypothesized that ginger extract (GE) ingestion increases skeletal muscle glycogen by enhancing fat oxidation. Thus, we investigated the effect of GE ingestion on exercise capacity, skeletal muscle glycogen, and certain blood metabolites in exercised rats. [Methods] First, we evaluated the influence of GE ingestion on body weight and elevation of exercise performance in rats fed with different volumes of GE. Next, we measured the skeletal muscle glycogen content and free fatty acid (FFA) levels in GE-fed rats. Finally, we demonstrated that GE ingestion contributes to endurance capacity during intermittent exercise to exhaustion. [Results] We confirmed that GE ingestion increased exercise performance (p<0.05) and elevated the skeletal muscle glycogen content compared to the nonGE-fed (CE, control exercise) group before exercise (Soleus: p<0.01, Plantaris: p<0.01, Gastrocnemius: p<0.05). Blood FFA levels in the GE group were significantly higher than those in the CE group after exercise (p<0.05). Moreover, we demonstrated that exercise capacity was maintained in the CE group during intermittent exercise (p<0.05). [Conclusion] These findings indicate that GE ingestion increases skeletal muscle glycogen content and exercise performance through the upregulation of fat oxidation.

Distribution and binding properties of sodium salicylate the human red blood cells were studied under various experimental conditions. The effect of tonicity and hemolysis on the steady state level of the drug within the human red blood cells were accounted for in this study. When the washed cells were suspended in normal saline solution, the drug was so rapidly permeated into red cells. Since the pH of the system forces nearly complete ionization of the drug, ionic diffusion through aqueous pores is thought to be the mode of salicylate transport. Human red cell binding capacity and association constant for salicylate were estimated. This work supports the view that the red cells act asan important reservior of salicylate.

Land resources should be managed not only for human utilizations but also for environmental preservation. Based on that, environmental capacity should be estimated in both environmental and developmental ways. This study was performed for developing an estimation model for relative environmental capacity, considering both Development Tolerance Index(DTI), which shows environmental and ecological conservation value and is based on national environmental assessment indicators of the Korea Ministry of Environment, and Development Attractiveness Index(DAI), which shows topographical characteristics and geographical accessibility. The relative environmental capacity in this study can be helpful to coping with the conflict in planning and managing the use of land resources. The relative environmental capacity in this study, however, did not include either environmental or ecological sensitivity of land resources. This limitation should be solved through further research.

In the 2015 revised curriculum, "creative and convergent talent prize" was presented as a human resource to be pursued by current curriculum. The core competencies that future talent should have are self-management capacity, knowledge information processing capacity, creative thinking capacity, aesthetic capacity, communicative competence, and community competence. The researcher believes that among the six core competencies, the ability to have more attention today is aesthetic capacity and that mathematics education should pursue it. The mathematical teaching methods based on Rudolf Steiner's anthroposophy education theory is an education that actively raises the aesthetic sensitivity of students. Therefore, this study investigates the features of educational methods based on the Steiner's anthroposophy and examines mathematics education methods based on them.

This paper discusses the merits of the community capacity and capacity building concepts, the strategies used for building community capacity and their implications for community health nursing. Community capacity is defined as the interaction of the human capital, organizational resources, and social capital existing within a given community that can be used to improve or maintain the health of the community. Community capacity building is one approach to promoting community health. This approach takes a comprehensive, dynamic, and multidimensional view of community needs and circumstances and places an emphasis on asset development, collaboration among community organizations, and community participation. The major strategies for community capacity building involve activities such as facilitating the development of an asset-based approach to community, developing leadership, establishing partnership, organization development, utilizing community resources, and developing public relations. The implications of community capacity for community health nursing are addressed in terms of the need for community health education and practicum, long-term commitment, partnerships, and a paradigm shift. The author suggests that the concept of community capacity building may be useful for improving the health of both the entire community and its individual residents.

To evaluate the factors that determine the transmission level of vivax malaria using vectorial capacity, entomological surveys were conducted from .lune to August, 2000. From 6 nights of human-bait collection in Paju, the human biting rate (ma) was counted as 87.5 bites/man/night. The parity of Anopheles sinensis from human baiting collections fluctuated from 41% to 71% (average 48.8%) of which the rate gradually increased as time passed on: 35.2% in Jun. ; 55.0% in July; 66.2% in Aug. From this proportion of parous, we could estimate the probability of daily survival rate of An. sinensis to be 0.79 assumed with 3 days gonotrophic cycle and the expectancy of infective life through 11 days could be defined as 0.073. Blood meal analysis was performed using ELISA to determine the blood meal source. Only 0.8% of blood meals were from human hosts. We could conclude that An. sinensis is highly zoophilic (cow 61.8%) Malaria is highly unstable (stability index < 0.5) in this area. From these data, vectorial capacity VC) was determined to be 0.081. In spite of a high human biting rate (ma), malaria transmission potential is very low due to a low human blood index. Therefore, we could conclude that malaria transmission by An. sinensis is resulted by high population density, not by high transmission potential. For this reason, we need more effort to decrease vector population and vector-human contact to eradicate malaria in Korea.

이 논문은, 외부 세계와 관계를 맺고 살아가는 터라, 사람이란 이미 완성된 어떤 존재가 아니라, 지금도 만들어지는 중이다, 라는 결론을 내린다. 이 결론에 이르기까지 다음 네 단계를 거친다. 첫째, 인간이 오로지 이성 존재일 수 있는가를 묻는다. 칸트처럼 인간을 '선의지'를 가진 도덕 행위자로만 묘사하는 것은 왜곡된 자화상처럼 여겨진다. 둘째, 오로지 '선의지'만을 발휘하여 보편 도덕법칙을 따를 수 있는가를 묻는다. 현실에서 보편 도덕법칙을 따르기가 불가한 것은, 도덕 행위자가 끊임없이 변화하는 외부 상황을 배제할 수 없는 처지이기 때문이다. 그럼에도 이성 명령에 따라 보편 도덕법칙을 지키라는 요구는 인간에게 지워진 '불운한 유산'이다. 셋째, 인간에게 '불운한 유산'이 지워진 것은, 마음과 몸을 '안'과 '밖'으로 나누는 이원론 때문임을 밝힌다. 이성 명령이란 '안'을 '밖'으로부터 지키라는 요구로서, 외부 환경에 민감한 감성을 일체 배제하라는 명령이다. 넷째, 삶이란 본래 '안'과 '밖'이 서로 상호작용하는 과정이다. 그렇다면 이성과 감성은 서로 분리될 수 없으며, 이성만으로는 살아가는 인간은 무기력할 따름이다. 결론은, 인간은 이성 아니면 감성 어느 한 극단으로 살지 않는다는 것이다. 인간은 '이성 존재'로 이미 완성된 어떤 자아가 결코 아니다. '인간적 동물'은 외부 세계와 상호작용으로 '만들어지는 자아'일 따름이다.

The stability of four hemoglobins (Hb) in dimer forms (low concentration) were investigated by the kinetics of denaturation. The rate constants of denaturation were obtained by variation of 280 nm absorption versus time in 10 mM Tris-HCl, 10 mM EDTA, pH 8.0 at $45^{\circ}C$ in the absence and presence of 0.5 M ethanol, dimethyl sulfoxide (DMSO), formamide, and glycerol. The results show the trend of rate constants in different co-solvents in the following order: chicken hemolysate < human hemolysate and chicken Hb D < chicken Hb A. The buried surface area was calculated for Hb samples in the absence of cosolvents. Accordingly, the trend points out that: chicken Hb D > chicken Hb A > human Hb A. These results suggest that both chicken hemolysate and chicken Hb D are relatively more stable than human and chicken Hb A, respectively. However, the denaturation rate constants of Hb in different co-solvents have designated the following order: ethanol > DMSO > formamide > glycerol. As a matter of fact, this phenomenon is an indication of an increase in the denaturation capacity (DC) and hydrophobicity, and a decrease in the surface tension of the solution in the preceding co-solvents.

Oxidative stress has been associated with a number of diseases in human. Among the sources that can generate oxidative stress, it has been reported that iron can generate reactive oxygen species (ROS)with thiol. In iron overload state, increased thiol levels in plasma appeared to be associated with human mortality. In this study we examined whether iron could interact with thiols in plasma, generating ROS. In human plasma, unlike with Fe(III), Fe(II) increased lucigenin-enhanced chemiluminescence in concentration-dependent manner, and this was inhibited by SOD. Boiling of plasma did not affect chemiluminescence induced by Fe(II). Hovever, thiol depletion in plasma by pretreatment with N-ethylmaleimide (NEM)decreased Fe(II)-induced chemiluminescence significantly, suggesting that Fe(II) generated superoxide anion by the nonenzymatic reaction with plasma thiol. Consistent with this findings, albumin, the major thiol contributor in plasma, also generated ROS with Fe(II) and this generation was inhibited by pretreatment with NEM. Treatment with Fe(II) to plasma resulted un significant reduction of oxygen radical absorbance capacity (ORAC) value, suggest that total antioxidant capacity could diminished in iron overload state. In conclusion, In iron overload state, plasma may be affected by oxidative stress mediated by nonenzymatic reaction of Fe (II)with plasma thiol.
