This study was designed to come up with a way of managing a cultural landscape forest by conducting research on the vegetation structure and growth characteristics. This study's target site, which was 45,201㎡ in size, was Pinus densiflora forest for Sugumagi placed at the entrance of Unmun Temple, Sinwon-ri, Unmun-myeon, and Cheongdo-gun in the southernmost part of Gyeongsangbuk-do, Korea. Sugumagi means the water of the valley flows far away, and where no downstream is visible according to feng shui. The historical sources of the Sugumagi Pinus densiflora forest at the entrance of Unmun Temple isn't clear. It waw only found at that location. The Pinus densiflora forest at the entrance of Unmun Temple is located in the waterway in terms of Feng Shui. The present condition of growth was investigated through a grid surveys of 98 trees and Pinus densiflora growth. As a result of the analysis of growth status, Pinus densiflora, Larix leptolepis, Zelkova serrata, Celtis sinensis, and Rhus javanica were distributed in the conopy layer, and 28 species including Ailanthus altissima were grown in the understroy layer, and 92 species, including Ampelopsis brevipedunculata, in the shrub layer. The plant community structure was divided into low, medium and high-density Pinus densiflora forests in the study area, based on the number in the conopy layer and the grade of and the trees analyzed. As a result of the analysis, the Pinus densiflora dominated the low, medium and high-density Pinus densiflora forests, and there were no competitive species. The relative dominance of the low-density Pinus densiflora forests was 46.9% on average, medium-density was 62.6% and 50.2% was found in high-density. The mean species diversity of Shannon in the low-density study was 0.7055, medium-density study was 0.8966 and the average species diversity of Shannon in the high-density study was 0.8317. The analysis of the age and growth of 25 sample trees in the Sugumagi Pinus densiflora forest shows that the distribution of the chest diameter (DBH) of the sample Pinus densiflora is 38 to 77cm with the average chest diameter being 61.1cm. The age was 84-161 years and the average was 114 years. In the Pinus densiflora forest, most(670,659, or 98.3%) of the tree trunk wound was collected for rosins during the Japanese colonia Era, Of the total 670, 659 were Pinus densiflora, 98.3% of the total. 394 were surgically repaired in 2005. For the preservation of the Sugumagi Pinus densiflora forest, dead trees should be replaced with substitute trees appropriate to the middle and south topography. It is demanded that foreign species such as Larix leptolepis in the research area should be removed and Pinus densiflora that underwent surgical operations should be regularly sterilized. It is also emphasized that the management of insecticide is important.

Objective of this research was to investigate the influence of pre-plant nitrogen levels in root media on plug seedling growth of radish cv. Soksungbommu. To achieve the research purpose, a root medium, the mixture of perlite, coir dust, and peatmoss (volume percentage of 30:35:35) was formulated and the N levels incorporated during mixing were controlled to 0, 100, 250, 500, 750, 1,000, and $1,500mg{\cdot}L^{-1}$. Then, the seeds were sown into 72-cell plug trays in which the root medium was packed. The measurements of growth and analysis of tissue and root media were conducted 2 and 4 weeks after sowing. Elevation of pre-plant N levels raised EC and turned down pH of root media. But, as seedling grew, the pH rose and EC get lowered in all treatments. The EC as well as $NH_4-N$ and $NO_3-N$ concentrations of root media declined gradually until week 2, but those declined sharply between weeks 2 to 4. The seedling growth 2 weeks after sowing showed quadratic response to pre-plant N levels with the highest growth in $250mg{\cdot}L^{-1}$ treatment and lagging growth in the treatments of lower or higher N levels than $250mg{\cdot}L^{-1}$. The seedling growth 4 weeks after sowing showed also quadratic response with the highest growth in $500mg{\cdot}L^{-1}$ treatment. The tissue N contents were get higher and those of K, Ca, and Mg were get lower as pre-plant N levels were elevated. Above results suggest that lower than $250mg{\cdot}L^{-1}$ in pre-plant N levels is optimistic for growth of plug seedling and avoidance of toxic injury in very young stage.

Purpose: The purpose of this study was to identify and compare role conflict and job satisfaction between nurses in ICU and nurses in general ward. Method: The subjects of this study consisted of 141 nurses employed at ICU and 201 nurses employed at general ward, who were recruited from 5 university hospitals with 500 beds located in Seoul and Gyeonggido. The instruments included role conflict scale developed by Kim and Park(1995) and job satisfaction scale translated and modified by Lee(1996). The collected data were analyzed using the SPSS WIN 10.0 program for descriptive statistics, t-test, ANOVA, and Pearson correlation coefficient. Result: In the two groups, there was a inverse correlation between role conflict and job satisfaction. In ICU, nurses' role conflict levels differed significantly depending on religion(p<.05), total experience(p<.05), scheduled to work as a nurse(p<.05). And nurses' job satisfaction levels differed significantly depending on total experience(p<.05), working period in current post(p<.001), scheduled to work as a nurse(p<.001), motive of choosing the nursing science(p<.01), and job satisfaction(p<.001). In general ward, nurses' job satisfaction levels differed significantly depending on marital status(p<.05), educational level(p<.01), total experience(p<.001), motive of choosing the nursing science(p<.01), and job satisfaction(p<.001). Conclusion: Summing up, the nurses at ICU showed higher level of role conflict than the nurses ay general ward. Therefore, it is needed to decrease the level of nurse's role conflict and improve their job satisfaction in ICU.

The purpose of this study was to examine the effects of child rearing behavior and child rearing involvement on elementary school children's stress. The subjects were 201 children selected from 2 elementary schools and their parents. Data was collected using the children's stress index, the child rearing behavior questionnaire, and the child rearing involvement questionnaire, and was statistically analyzed using t-test, one-way ANOVA (Duncan test), correlation analysis and multiple regression analysis. The study showed that there were some significant differences in children's stress according to the child's gender, grade, and scholastic achievement. Correlation analysis indicated that the child's stress and the mother's child rearing behavior had significant correlation, especially the warmth acceptance behavior of the mother indicated negative high correlation. Also, the child's stress and father's child rearing behavior had significant correlation, especially the rejection restriction behavior of the father indicated positive high correlation. Correlation analysis indicated that the child's stress and the mother's child rearing involvement had significant correlation, especially the family activities involvement of the mother indicated negative high correlation. As well, the child's stress and the father's child rearing involvement had significant correlation, especially the day to day guidance involvement of the father indicated negative high correlation. It was also found that rejection restriction behavior of the father, permissiveness non-intervention behavior of the father, day to day guidance involvement of the father, family activities involvement of the father, and warmth acceptance behavior of the mother were all significant predictors of the elementary school child's stress.

As the Internet spreads, many people have interests in e-CRM and product recommender systems, one of e-CRM applications. Among various approaches for recommendation, collaborative filtering and content-based approaches have been investigated and applied widely. Despite their popularity, traditional recommendation approaches have some limitations. They require at least one purchase transaction per user. In addition, they don't utilize much information such as demographic and specific personal profile information. This study suggests new hybrid recommendation model using two data mining techniques, association rule and classification, as well as intelligent agent to overcome these limitations. To validate the usefulness of the model, it was applied to the real case and the prototype web site was developed. We assessed the usefulness of the suggested recommendation model through online survey. The result of the survey showed that the information of the recommendation was generally useful to the survey participants.

The anti-inflammatory effects of glycosaminoglycan (GAG) derived from Isaria sinclairii (IS) and of IS extracts were investigated in a complete Freund's adjuvant (CFA)-treated chronic arthritis rat model. Groups of rats were treated orally with 30 mg/kg one of the following: [1] saline control, extracts of [2] water-IS, [3] methanol-IS, [4] butanol-IS, [5] ethyl acetate-IS, or [6] Indomethacin(R) as the positive control for a period of two weeks. The anti-paw edema effects of the individual extracts were in the following order: water-IS ex. > methanol ex. > butanol ex. > ethyl acetate ex. The water/methanol extract from I. sinclairii remarkably inhibited UV-mediated upregulation of NF-${\kappa}B$ activity in transfected HaCaT cells. GAG as a water-soluble alcohol precipitated fraction also produced a noticeable anti-edema effect. This GAG also inhibited the pro-inflammatory cytokine levels of prostaglandin $E_2$-stimulated lipopolysaccharide in LAW 264.7 cells, cytokine TNF-${\alpha}$ production in splenocytes, and atherogenesis cytokine levels of vascular endothelial growth factor (VEGF) production in HUVEC cells in a dose-dependent manner. In the histological analysis, the LV dorsal root ganglion, including the articular cartilage, and linked to the paw-treated IS GAG, was repaired against CFA-induced cartilage destruction. Combined treatment with Indomethacin(R) (5 mg/kg) and IS GAG (10 mg/kg) also more effectively inhibited CFA-induced paw edema at 3 hr, 24 hr, and 48 hr to levels comparable to the anti-inflammatory drug, indomethacin. Thus, the IS GAG described here holds great promise as an anti-inflammatory drug in the future.

Background: Video-assisted thoracoscopic sympathicotomy has been determined to be the best way to treat palmar hyperhidrosis. However, satisfaction with the surgical outcomes decreases with the onset of compensatory hyperhidrosis (CH) over time. The ideal level of sympathicotomy is controversial. Therefore, we compared the long-term results of R3 and R4 sympathicotomy. Methods: We retrospectively reviewed 186 patients who underwent video-assisted thoracoscopic sympathicotomy between September 2001 and September 2015. We analyzed the long-term results with respect to hand sweating and CH, and the overall satisfaction in 186 patients. Results: With respect to hand sweating, significantly more patients complained of overly dry hands in the R3 group (25% versus 3.7%, p<0.001) and of mildly wet hands in the R4 group (2.9% versus 13.4%, p=0.007). There was a significantly increased occurrence rate of CH in the R3 group (97.1% versus 65.9%, p< 0.001). The most frequent site of CH was the trunk area. The overall satisfaction was higher in the R4 group, but without significance (75% versus 85.4%, p=0.082). Significantly more patients reported being very satisfied in the R4 group (5.8% versus 22.0%, p=0.001). Conclusion: T he R4 group had a higher rate of satisfaction than the R3 group with respect to hand sweating. CH and hand dryness were significantly less common in the R4 group than in the R3 group. The lower occurrence of hand dryness and CH resulted in a higher satisfaction rate in the R4 group.

The purpose of this study was to analyse the belief about mathematics teaching of elementary preservice teachers and mathematics teachers. This study involved 100 respondents from the preservice teachers and 114 respondents from the mathematics teachers. The instruments used in this study consist 15 items of mathematical knowledges and 19 items of mathematical activities. The finding showed that preservice teachers emphasized the conceptual knowledge, whereas mathematics teachers emphasized the procedural knowledge in the mathematical knowledges. And preservice teachers emphasized the knowledge representation, knowledge generation, knowledge deliberation, knowledge communication, whereas mathematics teachers emphasized the use of knowledge(syntax) in the mathematical activities. Finally, even though two groups showed the significant difference in some items, preservice teachers and mathematics teachers emphasized the various mathematical knowledges and mathematical activities.
