  • 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.

  • In order to concludes that human being is in the making, not a being already perfectly made, this paper goes through four steps. The first step raises a question that human being is only a being of reason. The Kant's assertion that human being has a moral capacity of 'good will' seems to be distorted portrait of human being. The second step calls into a question that human being can obey universal moral laws. Any universal moral law can't be obeyed by moral agent, because he can't exclude his external situations which are ceaselessly changing. Nevertheless imperatives of reason which require to obey the universal moral laws seems to be a 'unfortunate legacy' to human being. The third step demonstrates that imperatives of reason are originated from dualism which have dichotomize "mind vs. body" as "internal capacity vs. external situation". According to dualism, imperatives of reason require internal capacity to exclude emotions or desires which are sensitive to external influences. The fourth step discusses that interacting of inner and outer is to be necessary for human being. Then, reason is to be really in one glove with emotions which are beginning form externals, otherwise reason can't stop being powerless to any external situation. Concludingly any human being is to be processing to a new being, not situating any extreme antagonism of "reason vs. emotion". Because of emotional human animal, not a perfect god, humans being is in the ceaseless process into the making a new self.

  • 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.

  • Purpose: This study was conducted to determine cell viability and differentiation capability of human periodontal ligament (PDL) cells and to elucidate the effects of cryopreservation on the activity of human third molar PDL cells by comparing PDL cells with and without cryopreservation. Materials and Methods: Human PDL fibroblasts obtained from immature third molars were cultured and divided into two groups. The experimental group was cryopreserved with a slow freezing rate of $0.5^{\circ}C/min$ from $4^{\circ}C$ to $-35^{\circ}C$ followed by plunging in liquid nitrogen at $-196^{\circ}C$ and cultured after fast thawing. The control group was cultured without cryopreservation. Cell viability, growth capacity and morphology were evaluated in both groups. Bivariate statistics were used to compare 2 groups and linear mixed model analysis was used to investigate the growth trends difference over time. Result: Cell viability and growth capacity were not significantly different between the 2 groups (P>0.05). Cultured cell of both groups showed fibroblast-like in appearance, and there were no significant differences in morphology between 2 groups. The mixed model analysis revealed no significant difference of growth capacity between 2 groups over time (${\beta}=-0.0009$; P=0.138). Conclusion: This study demonstrates that cryopreservation under control does not affect the biological properties of PDL cells, supporting the feasibility of autotransplantation of cryopreserved impacted third molars.

  • This paper reads Mary Shelley's Frankenstein (1818) in light of the 18th-century understanding of 'sympathy' including those of Hume and Smith and also in light of what Michael Hardt in our century has called "affective labor." I argue that the imaginative capacity and "seeing" are crucial in understanding Smith's idea of 'sympathy.' By showing how the monster's ugliness precludes any human character from sympathizing with him, Mary Shelley exposes that Smith's idea of sympathy fails to maintain social harmony. Mary Shelley revises Smith's 'sympathy' and makes it more radical by suggesting that the active affective labor could bridge the epistemological distance lying between the agent concerned and the impartial spectator. I first read Smith's idea of sympathy as an imaginative capacity which is inevitably influenced by 'seeing' and visual perception. Then I analyze the scenes in which the creature in Frankenstein fails to acquire any human sympathy due to his ugliness, and show how the specular nature of 'sympathy' is disrupted when one party is visually ugly and deformed. I conclude that affective labor and active moral reflection on the part of the spectator need to be provided when the agent concerned is 'ugly' and thus challenges our habitual epistemological boundary. Shelley's re-evaluation of Smith's sympathy, thus, suggests that affective labor may not be something that women alone have to perform, but an ethical practice that concerns all human beings and that can transform the otherwise flawed human capacity for sympathy.
