With the recent increasing interest in preventive medicine, observation has been made regarding the positive relationship between a routinized place that includes activity and health improvement. This study evaluates the effective value of a designed landscape for seeing a healing environment and sees the difference of the effective value of classified physical settings regarding Evidence Based Design. Therefore, the study evaluates the perceived restorativeness scale of Cheonggyceheon's 1.5km section and five type settings in the same section regarding how much it works as a healthy urban park. The research methodology used to study sub-settings' and the research site's restoration effects was observation and questionnaires. A PRS (Perceived Restorativeness Scale) questionnaire survey was the research tool employed. The study drew two major results. Firstly, PRS 6.12 is the score of the whole research site, so the study identifies that Cheonggycheon has a mental fatigue restoration function. Secondly, the sub-setting named 'Near Sidewall' was the most attention restorative, according to the ANOVA results. In conclusion, this study suggests significant information support regarding the reasons for creating green areas in urban settings by identifying a particular designed healing sit.
Bujeonghangamtang(扶正抗癌湯) has been used for cure of tumor as a traditional medicine without any experimental evidence to support the rational basis for its clinical use. This study was carroed out to evaluate the possible therapeutic or antitumoral effects of Bujeonghangamtang extract against tumor, and to carry out some mechanisms responsible for its effect. Some kinds of tumor were induced by .the typical application of 3-methylcholanthrene (MCA) or by the implantation(s.c) of malignant tumor cells such as leukemia cells(3LL cells) or sarcoma cells(Sl80 cells). Treatment of the Bujeonghangamtang water-extract (dailly 1mg/mouse, i. p.) was continued for 7 days prior to tumor induction and after that the treatment was lasted for 20 days. Against squamous cell carcinoma induced by MCA, Bujeonghangamtang decreased not only the frequency of tumor production but also the number and the weight of tumors per tumor bearing mice (TBM). Bujeongmngamtang also significantly suppressed the development of 3LL cell and S180 cell-implanted tumors in occurence-frequency and their size, and some developed tumors were regressed by the continuous treatment of Bujeonghangamtang extract into TBM. In vitro, treatment of Bujeonghangamtang extract had no effect on the growth of some kinds of cell line such as FsaII, A431 strain but significantly inhibited the proliferation of 3LL, S180 cells and augmented the DNA synthesis of mitogen-activated lymphocytes. Bujeonghangamtang also stimulated the migrative ability of leukocyte, the MIF and IL-2 production of T lymphocytes, but not IL 6 production of B cells. Bujeonghangamtang-administration to mice enhanced NK cells attivities. These results demonstrated that Bujeonghangamtang extract exhibited a significant prophylactic benefits against tumors and its antitumor activity was manifested depending on the type of tumor cells. And these results also suggested that effect of Bujeonghangamtang might be chiefly due to nonspecific enhancement of NK cell activities and cell-mediated immune responses.

This study attempted to analyze the relationship between school life satisfaction and acculturation of elementary students of north Korean refugees in Daegu and Gyeongbuk region. The socio-demographic characteristics of elementary students in Daegu and Gyeongbuk were different from in capital territory or other parts of Korea. The acculturation of students living in Daegu and Gyeongbuk was distinctive. The proportion of assimilation was slightly higher than that of integration. However, 42 percent of students belonging to separation and marginalization passively accepted south Korean culture, so that they would have a difficult time in adjusting to new culture. Students getting older and being used to school life strongly inclined to accept south Korean culture; while, students born in north Korea tended to resist acceptance of south Korean culture. Most students were satisfied with school life. The satisfaction level was high in the relationship with teachers and school environment; while, the satisfaction level in learning activity was relatively low. In the relationship between school satisfaction and types of acculturation, students actively accepting new culture were relatively highly satisfied with their school life. A standardized short-term education oriented program for north Korean adolescents refugees living in south Korea should be shifted into the long-term support policy reflected in class and attribute in terms of acculturation.
To support the fermentational superiority of Korean nuruks and maintain the various domestic nuruks, the optimal nuruk production of Andong-Soju, which was designated as an intangible cultural asset of Gyungsangbukdo province from 1987, was investigated. Different thickness of nuruks ($2.2{\sim}5.5\;cm$) were manufactured based on traditional Andong-Soju nuruk method, while the size of round form of nuruk was set to 23 cm. During the 3 weeks maturation, changes of water content, weight, pH, brix, the amount of reducing sugar, sac-charifying activity, viable cell and major microorganisms were determined, Also, ethanol fermentation abilities of the manufactured nuruks were evaluated using 20% glucose medium or 16% starch medium, respectively. Our results indicated that the production of high quality of Andong-Soju nuruk needs $4.0{\sim}5.5\;cm$ thickness and 3 weeks maturation without extraneous yeast addition. These results would be applied to production of homogeneous, and high quality of Andong-Soju nuruk.

Reaction characteristics of simultaneous removal of SOx and NOx have been investigated in a thermogravimetric analyzer and tubular fixed bed reactor using the $CuO/{\gamma}-Al_2O_3$ sorbent/catalyst. Sulfur removal capacity of $CuO/{\gamma}-Al_2O_3$ sorbent/catalyst is largely enhanced above both the temperature of $450^{\circ}C$ and the loading of 6wt% due to the participation of alumina support in a sulfation reaction. The NO reduction efficiency of 8wt% $CuO/{\gamma}-Al_2O_3$ sorbent/catalyst shows the maximum value at $370^{\circ}C$ and then decreases with the increase of reaction temperature due to the oxidation of $NH_3$ gas. The presence of sulfate on the surface of sorbent/catalyst enhances the optimum reaction temperature showing the maximum deNOx efficiency. In the simultaneous removal of SOx and NOx at $250^{\circ}C$. deNOx activity of $CuO/{\gamma}-Al_2O_3$ sorbent/catalyst is rapidly decreased due to the formation of ammonium salts such as $NH_4HSO_4$. In the simultaneous removal reaction of SOx and NOx, the optimum temperature showing the maximum deNOx efficiency increases to $400^{\circ}C$ due to the presence of $SO_2$ gas.
With a sample of 147 Korean small and medium size companies, this study examined the relationships among degree of information orientation, corporate culture, degree of information management implementation and selected business performances in the process of implementing IMS(Information Management System). Information orientation is defined as company-wide understanding and implementation of the underlying philosophy, principles, approached, and tools of information improvement programs. It is assumed that successful implementation of information improvement programs requires a information-oriented mind-set of the employees. It is also assumed that successful implementation of information improvement programs require strong support from s corporate culture that emphasizes continues improvement. Adopting the competing values model of Quinn and McGrath(1985), corporate culture is classified into 'flexible' versus 'controlled culture' and 'outer-directed' versus 'inner-directed culture'. This study examined how such fitness influenced the implementation of information innovation programs and business performance. Implementation of information innovation programs was measured through various factors, such as leadership, strategic information planning, human resources focus, customer and market focus, process management, and information analysis and application. Business performance was measured through non-financial performance measuresm such as employee results, process results, information results, and customer results, and through perceived financial performance measures.
The purpose of this study is to investigate the perception and actual condition of early childhood teachers about the activities of cooperative art in early childhood education institutions. The subjects of the study were 280 teachers of early childhood education institutions in Y city. The research method was a questionnaire survey on the perception and actual condition of the cooperative art activities. For the research problems, frequency, percentage, and average were calculated by using descriptive statistics, and t - test, F - test, and ${\chi}^2$ - test were conducted to examine the differences according to background variables of early childhood teachers. In conclusion, this study showed that the need for cooperative art activities of early childhood education institutions was highly perceived, and there were significant differences according to the background variables of teachers in educational goals, contents and method. There were significant differences according to the teachers' background variables in the actual cooperative art activities in terms of frequency, method, time, evaluation method, teacher training and support. Based on the results of this study, various supporting methods such as activities plan and method, teacher education and training appropriate for the cooperative art activity program and the presentation of young children are sought so that more desirable and efficient cooperative art activities can be operated in the field of early childhood education suggesting that it should be done.
Objectives The present study aimed to investigate the change in marker compounds, anti-oxidative and anti-inflammatory effects of salt-water processed Cortex Eucommiae. Methods To evaluate the influence of processing on anti-oxidant effect of Cortex Eucommiae, changes in total phenol, total flavonoid, 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) free radical scavenging, and ferric reducing antioxidant power (FRAP) between processed and raw Cortex Eucommiae were assessed. In addition, nitrite assay was conducted to determine the influence of processing on anti-inflammatory effect of Cortex Eucommiae. Cell viability was also examined as to elucidate whether processing affects cytotoxicity of Cortex Eucommiae. Finally, high-performance liquid chromatography (HPLC) analysis was conducted to monitor changes in pinoresinol diglucoside amount of processed and raw Cortex Eucommiae. Results Salt-water processed Cortex Eucommiae showed higher total phenol and flavonoid amount, compared to raw Cortex Eucommiae. Furthermore, anti-oxidative activity of processed Cortex Eucommiae was improved as discovered in DPPH, ABTS, and FRAP assays. Anti-inflammatory effect of Cortex Eucommiae was also enhanced following salt-water processing, as evidenced in nitrite assay. HPLC analysis found that the amount of pinoresinol diglucoside, widely known as the marker compound of Cortex Eucommiae, increases through salt-water processing. All experiments were performed with non-toxic concentration of Cortex Eucommiae; processing did not affect the cytotoxicity of Cortex Eucommiae up to the currently adopted concentration. Conclusions The present results support that salt-water processing of Cortex Eucommiae is beneficial in terms of marker compound amount, anti-oxidative, and anti-inflammatory activities. Additional investigations are needed to standardize the processing method of Cortex Eucommiae.
The earliest reports of the use of electrical energy to directly stimulate bone healing seem to be in 1853 from England, the techniques involved the introduction of direct current into the non-united fracture site percutaneously via metallic needles, with subsequent healing of the defect. One endpoint of the periodontal therapy is to generate structure lost by periodontal diseases. Several procedural advances may support regeneration of attachment, however, regeneration of alveolar bone does not occur consistently. Therefore, factors which stimulate bone repair are areas for research in periodontal reconstructive therapy. Effects of cytokines or growth factors on bone repair are examples of such areas. Another one is electrical current which occurs in bone naturally, so that such bone may be particularly susceptible to electrical therapy. The purposes of this study were to observe the effects of electrical stimulation on the normal periodontium, to determine whether the electricity is the useful means for periodontal regeneration or not. Forty rats weighted about 100 gram were used and divided into 4 groups, the first group, there was no electrical stimulation with the connection of electrodes only. In the second group, there was stimulated by the 10 mA during 10 minutes per a day, in the third group was stimulated by the 25 mA , and the fourth by the 50 mA. At 3, 5, 10 and 15 days post-appliance , two rats in each group were serially sacrificed. and the maxillae and the mandible processed to paraffin, and the specimens were prepared with Hematoxylin-Eosin stain for the light microscopic evaluation. The results of this study were as follows : 1. There was the distinct reversal line on the lingual alveolar crest, whereas a little changes in the labial alveolarcrest to the duration and amount of currents. 2. In 50 mA group, the cells were highly concentrated at the apex of anterior teeth, and was observed the necrotic tissue. In posterior root apex, the hypercementosis was appeared, and newly formed cementum layer has been increased continuously with the time. 3. The periodontal ligament fiber and Sharpey's fiber were arranged in order, and the bone trabeculae were increased as the experiment proceeded by, relatively the bone marrows were decreased. 4. In the pulp tissue, the blood vessels were increased with blood congestion in the experimetal specimens remarkably, and the dentinal tubules were obstructed . 5. The osteoblasts in alveolar bone proper had been showed highly activity, and also observed the formation of bone trabeculea. In the conclusion, it was suggested that the electrical stimulation has influence on the periodontium and the pulp tissue. However, there might be the injurious effects.
