The higher valence state of iron i.e., Fe(VI) was employed for the treatment of Cu(II)-EDTA in the aqueous/waste waters. The ferrate(VI) was prepared through wet oxidation of Fe(III) by sodium hypochlorite. The purity of prepared Fe(VI) was above 93%. The stability of Fe(VI) solution decreased as solution pH decreased through self decomposition. The reduction of Fe(VI) was obtained by using the UV-Visible measurements. The dissociation of Cu(II)-EDTA complex through oxidation of EDTA using Fe(VI) and subsequent treatment of organic matter and metal ions by Fe(III) reduced from Fe(VI) in bench-scale of continuous flow reactor were studied. The removal efficiencies of copper were 69% and 79% in pH control basin and reactor, respectively, at 120 minutes as retention time. In addition, Cu(II)-EDTA in the reactor was decomplexated more than 80% after 120 minutes as retention time. From this work, a continuous treatment process for the wastewater containing metal and EDTA by employing Fe(VI) as muluti-functional agent was developed.

The purpose of this study was to examine the professionalism of estheticians in gusan and jeonju city, jeollabuckdo province. Total 290 questionnaires were collected. The period of research was from april 1 to 20, 2009. The findings of the study were as follows: First, when their professionalism was checked in light of the selected variables, their age, education and work years at current job made no statistically significant differences, but that was different according to life satisfaction and job satisfaction. By life satisfaction, the estheticians who found their lives satisfactory professionalism better than the others who didn't(t=2.77, p<.01) By job satisfaction, the estheticians who were contented with their job took the most positive professionalism, and those who found their job just not to be bad looked at it less positively than the others who were discontented(F=6.06, p<.01). Second, when the correlation of their professionalism of the sub-factors was investigated, there was a statistically significantly positive correlation among faith in autonomy(r=.595, p<.001), use of professional organization(r=.428, p<.001) and sense of mission(r=.492, p<.001). Their faith in services(r=-.634, p<.001) had a statistically significantly negative correlation to faith in self-control(r=-.485, p<.001).

The purpose of this study was to analyse the gait characteristics of stroke patients walking on a Zebris system, through quantitative three-dimensional biomechanical analysis. They underwent a continuous rehabilitation training program (RTP). A comparison was made between 3 month and 6 month RTP participants. Their ages were between 60 and 65. The data were analyzed by t-test. The result of comparative analysis of the two groups can be summarized as below. Temporal-spatial data, sagittal plane angular kinematics data, and peak ground reaction force and max pressure data showed that there were no significant differences between the 3 month RTP group and the 6month RTP group (Table 2, Table3, Table 4). It can be suggested that patients with hemiplegia after stroke can improve their walking function through continuous RTP participation.

Lots of geographic phenomena have dynamic spatial patterns with time changes, and there have been lots of researches on exploring these dynamic spatial patterns. However, most of these researches focused on the static pattern analysis in a given period, rather than dealing with dynamic changes in the spatial pattern over time with the continual or cumulative perspective. For this reason, investigation of the inertia of spatial process in terms of temporal changes is needed. From this background, the purpose of this paper is to propose the methodology to explore the changes in spatial pattern cumulatively by considering the inertia of the spatial statistics over time, and to apply it to the case study That is, we introduce the new spatial statistic, and produce the z-values of the statistic using Monte Carlo Simulation, and then to explore the changes in spatial patterns over time cumulatively. To do this, the method to combine the J statistic with CUSUM statistic for exploring spatial patterns, and to apply it to the changes in the commercial landuse in Erie County, New York State. Through the proposed method for spatio-temporal Patterns, we could explore continual changes effectively in the spatial patterns reflecting the statistics by temporal spot cumulatively.

In order to live up to public expectations, universities dedicate their best efforts to cultivating all Essential Competencies for outstanding individuals, especially reorganizing and improving their general education curricula and methods of teaching and learning, in light of the fact that a cutting-edge technology in a specific field does not bear a long span in the modern society. Through a Grounded Theory approach, the aim of this research is to study undergraduates' Experience Process of Action Learning designed to foster their Essential Competencies. With broadly selected 15 students from the courses for Essential Competencies, the method of theoretical sampling was employed so as to secure the diversity of the subjects' characteristics and backgrounds. After in-depth interviews, the data from the subjects were analyzed on the basis of Grounded theory approach of Strauss and Corbin. The conclusions of this analysis are as follows; Firstly, a learning coach should play a different role depending on the levels of Action Learning. Secondly, some time for introspection should be taken for the effective operation of Action Learning. Thirdly, learners ought to solve the problems faced during the learning process on their own. Fourthly, the aims of courses for Essential Competencies are also needed to be focused.

The purpose of this study was to evaluate the knowledge level of pressure ulcer among hospital nurses through a cross-sectional survey by using the pressure ulcer knowledge assessment tool of Beitz et al.(1998). The total of subjects was 160 voluntary participants (60 were from Hospital A and 100 were from Hospital B) working at adult patients' units in two university hospitals located in the same city. None of the hospitals had expert nurses of pressure ulcer nor provided a regular pressure ulcer education program during the past one year. The survey tool consisted of 32 true-false items which were grouped into the risk factors knowledge category(13 items), the wound assessment knowledge category(4 items), and the treatment methods knowledge category(15 items). An internal consistency reliability test of the tool yielded an overall coefficient of 0.72; the coefficient for the risk factors knowledge category was 0.40, that for the wound assessment knowledge category was 0.33; that for the treatment knowledge category was 0.54. The main findings of the study are as follows. 1) Demographic characteristics of the two hospital nurses were similar except for the educational level(p=0.029) and the work units(p=0.001). These observations were maintained even if Hospital A and B were separately compared. 2) The knowledge level of the subjects about pressure ulcer in general was low as indicated by 53.3 points(of 100 possible points) on average. The knowledge level about treatment methods of pressure ulcer was the lowest as indicated by 47.0 points on average. 3) No correlation between the knowledge level of the pressure ulcer and the demographic characteristics of nurses was found except that the knowledge level of I.C.U. nurses was significantly higher(p=0.0003) than that of nurses in other units(p=0.2926) in the case of Hospital A. 4) The knowledge level of nurses in Hospital B was higher than for nurses in Hospital A. The reason was not identified, but it seems that it is related to the role of the I.C.U. or some other factors. The study results confirmed the existing literature that knowledge level of nurses about pressure ulcer is low regardless of age, educational level, or work experience. However, the working place(unit) affected the knowledge level. Further research on the exact reason for the differences in the knowledge level is needed in the future.

This paper has focused on the geographical patterns of migrations and the influence of housing value(apartment) per pyung on the migrations within the one city(Seoul) for 1995$\sim$2003. The migration flows which are composed of the origin, the destination and the number of migrants, are examined at the administrative gu and dong level. As most migrations occur among adjacent gus and dongs, short-distance migration is prominent But there is a tendency for the short-distance migrations to occur between specific regions. Since the economic crisis of 1997 out of which Korea was rescued by IMF, differentiation of housing price is so evident that residental relocation is selective among dongs. It seems that the differentiation of housing price has begun to facilitate the relocation of households. Certain social groups are excluded from high-quality residences, as they cannot afford the high price. The number of migrants between dongs is closely related to the variation of the housing value per pyung within dongs. The short-distance migration may reflect this phenomena simultaneously. It seems that the intra-urban migrations in Seoul play a important role to produce and reinforce the residential segregation.

Purpose: This study examined the effectiveness of a hand massage combined with analgesics on pain control in hospice patients with terminal cancer. Methods: This study is a quasi-experimental study with a single group time series design. The study included 25 terminal cancer patients who were admitted to a hospice ward. Each patient's pain level was measured after analgesics use only (control group). When patients complained of pain again, the pain level was assessed after administering a combination of hand massage and analgesics (experimental group). As for the experimental treatment, the participants were provided with oil hand massage on each hand for 5 minutes. Results: The experimental group and the control group showed no significant differences in the changes of pain score (F=0.74, P=0.3939). Conclusion: Although the pain level of the experimental group did not significantly improve compared with the control group, their pain levels tended to be low to begin with. Thus, a complementary utility value of hand massage cannot be completely excluded in terminal cancer patients. Since the pain level significantly changed according to the dosage of analgesic, nurses need more education and research on analgesic drug therapy for terminal cancer patients.
