The Korean government introduced a private-initiative park project to prevent further environmental damage caused by the abolition of parks. The private-initiative park project is expected to affect the connectivity of the green space system by creating a part of the park site as a non-park facility. The purpose of this study is to analyze the change in the connectivity of the green space system in relation to the private-initiative park project. The spatial scope of this study is in Cheongju, Korea. There were 8 private-initiative park projects selected as research subjects. The IIC indicator and d_IIC indicator, which are widely used in the analysis of green space connectivity, were used as analysis methods. Changes in connectivity according to four scenarios were simulated. Upon analysis, the results revealed that private-initiative park projects can reduce the overall connectivity of green spaces. The connectivity of private-initiative park projects can be improved compared to the situation of unplanned development while maintaining the current state. Lastly, changes in connectivity due to private-initiative park projects vary by region. This study was meaningful as an early study that analyzed private-initiative park projects in terms of the connectivity of green areas and is expected to be used for the improvement of the park and green space system in the future.

Background: Micafungin, a potent inhibitor of 1,3-β-D-glucan synthase, is a novel antifungal agent of the echinocandin class. In vitro study showed that micafungin was effective against Aspergillus species as well as Candida species, but clinical data on the prophylactic efficacy against invasive fungal infections (IFIs) other than candidiasis are still lacking. Materials and Methods: We identified 60 consecutive adult hematopoietic stem cell transplantation (HSCT) recipients who received at least 3 doses of micafungin during neutropenic period. Micafungin was started as an alternative in patients who were intolerant or had adverse events (AEs) to primary prophylactic antifungal agents. We retrospectively reviewed the medical records and analyzed the efficacy and safety of micafungin for prophylaxis against IFIs. Results: The patients either had autologous (n=9) or allogeneic (n=51: 1 syngeneic, 24 sibling, 26 unrelated donor) HSCT. Itraconazole oral solution (n=58) was the most frequently used first line antifungal agent for prophylaxis and was administered for median 11 days. The most frequent cause of switch to micafungin was vomiting (n=42). The duration of neutropenia and micafungin administration was median 13 and 12 days, respectively. A successful outcome was achieved in 45 (75%) patients. Empirical antifungal therapy was initiated in 13 (22%) patients. There were 2 cases (3.3%) of breakthrough fungal infections which comprised a probable invasive pulmonary aspergillosis and a possible invasive fungal sinusitis. There was no case of invasive candidiasis. A total of 53 (88%) patients experienced at least one AE regardless of causality during micafungin administration. The most frequent AEs were hypokalemia, vomiting, diarrhea, and elevated serum aspartate aminotransferase or alanine aminotransferase. Among the aforementioned AEs, only 1 case of diarrhea could be classified as a probable relation with micafungin when causality was assessed. There was no AEs that caused discontinuation of micafungin. Conclusions: Micafungin seems to be a safe and effective agent for prophylaxis of IFIs including aspergillosis as well as candidiasis in HSCT recipients. However, further large, prospective, and randomized comparative studies are warranted for aspergillosis.

The biological surveys were performed at seven sites in the Gangjin bay from February, 1998 to November, 2001. In order to analysis of environmental variation, numbers of heterotrophic bacteria, general fungus and fecal coliforms were enumerated in each sample. The result showed that variation range of heterotrophic bacteria, general fungus, and fecal coliforms were 2.9 x 10^(3)~9.6 x 10^(3) CFU/ml, 17.2~80.1 CFU/ml, and 6.3~682.5 CFU/100ml for four tears(1988~2001), respectively. Density of heterotrophic bacteria and general fungus were gradually decreased for four tours, while fecal coliforms were suddenly increased. Specially, numbers of fecal colifoms were increased the more 100 times in 2001 than that 1998. We think that it was probably caused a little rainfall in February, 2001. There result suggests that ecosystem of Gangjin bay were mainly regulated by 2~3 factors, which were inflow of fresh water, salinity and variation of water temperature.

This study suggests solutions to the problem of consolidation settlement or lateral movement, which may occur when roads or civil structures are constructed on soft clay. It also presents a proposal to determine appropriate height and time of embankment for early construction of abutment, on the basis of soil parameters in terms of reverse analysis. The following shows the summary of the study. (1) The Hyperbolic method was applied to the field measurement to compute a predictable final settlement. (2) The field measurement was analyzed by Asaoka method and a reverse analysis was carried out on the coefficient of consolidation of the vertical drain method. (3) The target amount of settlement was determined by the try and error method, which considered consolidation settlement to form the planned height. (4) Appropriate heigh and time of stepped embankment was determined to reach the target amount of settlement. (5) Slope stability of the step embankment was examined.

The rates of absorption of carbon dioxide into water were measured in a stirred cell with plane interface in the presence of fine solids such as activated carbon, white carbon and fused alumina at 25℃ and 1 atm. Experiments for slurries of activated carbon and white carbon showed that the absorption rates increase significantly, which could be explained by the adsorption capacity of these fine particle. Meanwhile, the absorption rates for slurry of fused alumina without adsorption capacity of dissolved gas in slurry were less than those for water. The enhancement of gas absorption into slurries of activated carbon and white carbon could be explained by the diffusion equation based on penetration theory of dissolved gas.

Inherent merits fabricating thin wafers motivated the development of laser dicing machines. In this study, the dynamic characteristics of the prototype of a laser dicing machine has been evaluated using ANSYS based modal and harmonic analysis. The computation shows that the supporting structure of the laser tube which is a guide of laser beams is stable in terms of the dynamic stiffness. But, the thickness of the beams supporting the upper structure of a laser dicing machine has to be increased.

In this study, a systematic design scheme was developed to reduce a subjective design of micro/mesoscale machine tools. Based on this developed method, the optimization of the size of micro/mesoscale machine tools was performed. These computations include individual mathematical modeling of key parameters such as volumetric error, machine working space, and static, thermal, and dynamic stiffness. In case of dynamic stiffness, it was supplemented with a hammer impact test to identify the dynamic characteristics of the joints.
