This study analyzes the processes of change in oral health behaviors induced by oral health education for 23 university students. To this end, we analyzed the changing patterns of the stages of change and motivational components for each oral health behavior. Additionally, we performed an in-depth interview-based investigation of the factors influencing such motivational components. Oral health education was performed twice with a concrete purpose of changing the participants' behaviors in complying with the practice of proper brushing and flossing as the main oral health management, and checking the nutrient facts as a good dietary habit. Upon completion of these two sessions of oral health education, the level of change in oral health behavior was assessed by measuring the stages of change and motivational components for each oral health behavior. In order to gain an in-depth understanding of the reasons for the changes that were demonstrated more markedly during the second education session than during the first session, collective interview surveys were carried out after the second session. The contents of the recorded interviews were categorized into subscales of distinctive concepts on the basis of the items of a health behavior model. The study had the findings as below. First, after the first and second education sessions, some behaviors showed positive changes from lower to higher levels of practice. Second, self-efficacy about oral health behavior was high or perceived barriers were low when its necessity and benefits were clearly perceived. Third, educational features such as the practice and participation-centered education, and examining their own oral conditions influenced the participants' oral health awareness and behavioral changes. There is a need for oral health education capable of leading to practical behavioral changes by establishing concrete strategies of deriving various motivational components at each stage of the processes of change.

This study aims to suggest strategies of development and management for large parks by examining experimental cases of park governance models related to a shift away from public administration. The shifts towards governance as well as public-private partnership in city parks have involved the need for new public management. This study has analyzed two exemplary cases of Presidio Park and Sydney Harbour National Park in the aspects of planning process and management strategies, as the results derived the meaning and effect of park governance management and is also an essential prerequisite for the achievement of the model. There are six dimensions of research frames--namely policy, governance, partnership, finances and funds, design and maintenance-management, and evaluation-monitoring-taken as the basis for this study. Through the analysis, several key characteristics of these cases were elicited. First, the park planning process must be consistent in carrying a policy from planning to implementation, and furthermore, an independent operation body which can properly authorize an execution and uphold its responsibility from the public could serve in adaptable park services. Second, it has been suggested to build various partnerships with PAs and NGOs, private corporations, community groups, and academic institutes that allow it to expand the diversity of the park activities. Third, there has been experimental exploration to achieve a financially self-sufficient model by establishing internal revenue models and hence allow the reduction of reliance on public finances. The result of this type of park management would allow for improving park quality and make the park space a vital part of the local economy. Fourth, the strategies for a local community's participation are needed to allow the community to become a producer as well as a consumer. This study shows that the direction and significance of the park governance model regarding the fact that the plans sought by the two parks are extending the layout of public-centered discussion to the private sector and the third non-governmental sector including to the local community group. This shows both implications and limitations, such as the risk of privatization through non-governmental activities at the park or the violation of essential functions as a public good due to a profit-generating management policy for securing financial self-sufficiency. At the current point in which plans are under way for the development and management of large parks, a park governance model requires continuous study and expansion of discussion in the future.
Purpose : Vascular endothelial growth factor(VEGF) is a key cytokine for controlling vascular permeability and angiogenesis, which is one of the major findings in airway remodeling. However, it is not well known if it is associated with acute lower respiratory tract disease such as lobar pneumonia. The aim of this study is to compare serum VEGF levels in patients with asthma according to its severity and duration of cough, and to compare its levels with children with lobar pneumonia. Methods : Using a sandwich enzyme-linked immunosorbent assay, the serum VEGF levels were measured in 16 mild asthmatics, 14 moderate to severe asthmatics, six children with lobar pneumonia, and 22 control subjects. The asthmatics were also classified into three groups according to the duration of cough. Serum VEGF levels were compared in each group. Results : Serum VEGF levels were significantly increased in the children with moderate to severe asthma and lobar pneumonia compared to the children with mild asthma and control subjects. Serum VEGF levels were higher in children with chronic coughs of more than two weeks than in children with coughs lasting less than two weeks. Serum levels of VEGF showed positive correlations with blood platelet and white blood cell counts. Conclusion : VEGF increased according to the severity of asthma and duration of cough in children with asthma. It may play an important role not only in chronic airway inflammation, but also in the acute inflammation in children with lower respiratory tract disease.

The cDNA of CCF (coelomic cytolytic factor)-like gene (EC 3.2.1.16), a kind of glycosyl hydorlase, was isolated and cloned from the midgut of the earthworm Eisenia anderi. The size of nucleotide sequence appeared to be 1,152 bp and its predicted coding region was composed of 384 amino acid residues including the initiation methionine. The 17 residues at N-terminal end in the deduced amino acid sequence were regarded to be a signal peptide. Based on the amino acid sequence analysis, it appeared that this CCF-like protein could belong to glycosyl hydrolase family 16 (GHF16) and showed a high sequence homology of about 79~99% with CCF and CCF-like proteins from other earthworm species. The CCFs and CCF-like proteins from various earthworm species exhibited a 100% homology in the polysacchride-binding motif and glucanase motif. It has been reported that the CCFs isolated from E. fedita appeared to show a broader pattern recognition specificity than those from other earthworm species because this species resides in decaying organic matter showing very high microbial activity, implying that CCF-like protein isolated in this study from E. andrei might exhibit a broad substrate specificity that is a useful characteristic for industrial application. A phylogenetic analysis using the deduced amino acid sequences of CCF-related proteins through the BLASTX revealed that GHF16 families could be divided into three groups of metazoa, viriplantae and eubacteria subfamily. Subsequently the CCF-related proteins of metazoa subfamily could clearly be subgroup into lophotrochozoan and edysozoan type including a deuterostome origin. Further understanding of the biological properties of E. andrei CCF-like protein should be addressed to regulate the ${\beta}$-D-glucan hydrolysis and production for the industrial uses.

Objectives: To assess the functional outcome of Bankart repair and rotator cuff repair using miniopen technique in patients with recurrent shoulder dislocation(8 cases) with rotator cuff tears and Bankart lesion of over 40 years. Materials and Methods: From May 1991 to January 2002, twenty two patients were available to participate in the study. Mean age was 52 years old(41-67), Follow-up evaluations averaged 50.5months(10-147). Results: The patients(22 cases) were divided into two groups. Group 1: with recurrent shoulder dislocation(8 cases) with rotator cuff tears and Bankart lesion in patients over 40 years old. Group 2: without Bankart lesion(14 cases). In Group 1, mean average of forward flexion and abduction improved from 122 degrees to 154 degrees at the final follow-up and from 115 degrees to 161 degrees respectively. In terms of University of Pennsylvania patient self-assessment of pain score and VAS, scores improved from 11.0 to 5.5 and from 5.4 to 2.5 respectively. In terms of UCLA score & Constant score, scores also improved from 20.2 to 29.6 and from 48.6 to 69.0 respectively. Functional outcome of Group 1: two patients with excellent, four patients with good, and two patients with fair. Functional outcome of Group 2: two patients with excellent, six patients with good, five patients with fair, and one patient with poor. But they had no statistical significance between the two groups. All cases were improved shoulder pain at the final follow up. And six patients were satisfied with the outcome of shoulder function. Conclusions: This study demonstrates the effectiveness of Bankart repair and rotator cuff repair using miniopen technique in patients with recurrent shoulder dislocation(8 cases) with tears of rotator cuff and Bankart lesion older than 40 years. We recommend Bankart repair and rotator cuff repair at the same time.

This study developed an SSI (Socio-Scientific Issue) discussion program that applies a creative technique called six thinking hats, and then investigated the differences in argumentation patterns and effects on the decision-making abilities of each character feature of students between SNS debate and existing face to face debate. There were three SSI themes - Designer Babies, embryonic stem cell study, and legitimacy of abortion. Students were divided into two groups, the debate group using SNS and face to face debate group. The character patterns of students were divided to 'extraversion,' 'agreeableness,' and 'conscientiousness' through test sheets for character features for each student. Both groups were educated for creative discussion methods using six thinking hats and then, the class progressed. As a result of analyzing argumentation patterns used in SNS debate and face to face debate, the most used argumentation pattern was the "cause pattern." But comparing to face to face debate, other patterns (mark, inference, authority, motive) were also used in SNS debate. The study analyzed three factors of decision-making ability for each character feature of students such as complexity, perspectives, and inquiry. As a result, for 'complexity' factor, there was a significant difference between SNS debate group and face to face debate group only in the student group of Agreeableness. For 'perspectives' factor, there were significant differences between SNS debate group and face to face debate group in all three characters. Finally, for inquiry, there were no significant differences between SNS debate group and face to face debate group in all three characters. Accordingly it would be necessary to apply SNS debate using the six thinking hats in SSI education to enhance perspectives.

Purpose : To generate a Korean specific brain template, especially in patients with Alzheimer's disease (AD) by optimizing the voxel-based analysis. Materials and Methods : Three-dimensional T1-weighted images were obtained from 123 subjects who were 43 cognitively normal subjects and patients with 44 mild cognitive impairment (MCI) and 36 AD. The template and the corresponding aprior maps were created by using the matched pairs approach with considering differences of age, gender and differential diagnosis (DDX). We measured several characteristics in both our and the MNI templates, including in the ventricle size. Also, the fractions of gray matter and white matter voxels normalized by the total intracranial were evaluated. Results : The high resolution template and the corresponding aprior maps of gray matter, white matter (WM) and CSF were created with the voxel-size of $1{\times}1{\times}1\;mm$. Mean distance measures and the ventricle sizes differed between two templates. Our brain template had less gray matter and white matter areas than the MNI template. There were volume differences more in gray matter than in white matter. Conclusion : Gray matter and/or white matter integrity studies in populations of Korean elderly and patients with AD are needed to investigate with this template.
Ultramafic xenoliths from southeastern part of Jeju Island can be grouped into two types: Type I and Type II. Type I xenoliths are magnesian and olivine-rich peridotite (mg#=89-91), which are commonly found at the outcrop. Most previous works have been focused on Type I xenoliths. Type II xenoliths, consisting of olivine, orthopyroxene and clinopyroxene with higher Fe and Ti components (mg#=77-83) and lower Mg, Ni, Cr, are reported in this study. They are less common with a more extensive compositional range. The studied Type II xenoliths are wehrlite, olivine-clinopyroxenite, olivine websterite, and websterite. They sometimes show ophitic textures in outcrops indicating cumulate natures. The textural characteristics, such as kink banding and more straight grain boundaries with triple junctions, are interpreted as the result of recrystallization and annealing. Large pyroxene grains have exsolution textures and show almost the same major compositions as small exsolution-free pyroxenes. Although the exsolution texture indicates a previous high-temperature history, all mineral phases are completely reequilibrated to some lower temperature. Orthopyroxenes replacing clinopyroxene margin or olivine indicate an orthopyroxene enrichment event. Mineral phases of Type II are compared with Type I xenoliths, gabbroic xenoliths, and the host basalts. Those from Type II xenoliths show a distinct discontinuity with those from Type I mantle xenoliths, whereas they show a continuous or overlapping relation with those from gabbroic xenoliths and the host basalts. Our petrographic and geochemical results suggest that the studied type II xenoliths appear to be cumulates derived from the host magma-related system, being formed by early fractional crystallization, although these xenoliths may not be directly linked to the host basalt.
This study was carried to investigate the physicochemical and microbiological characteristics of seasonal salted-Kimchi cabbage order to provide basic data for optimal salting and storage condition of seasonal Kimchi cabbage. Generally, fall season samples had slightly higher pH and acidity value than the other seasonal salted Kimchi cabbage. The soluble solids content of spring, summer, fall and winter samples were 5.95%, 6.18%, 6.29% and 7.76%, respectively. The salt content of all the seasonal salted Kimchi cabbage samples were insignificant. The number of microbial bacteria in the summer samples were generally much more significant than spring and winter samples. There was no significant difference in the color of seasonal salted Kimchi cabbage. As for the texture properties, the firmest samples in the surface rupture test were the spring samples (force: 4.92 kg), and the hardest samples in the puncture test were the summer samples (force: 11.71 kg). In the correlation analysis of the quality characteristics of seasonal samples, the soluble solids content and hardness of the seasonal salted Kimchi cabbage was significantly correlated at 1% significance level. Also, in the principal component analysis, F1 and F2 were shown to explain 27.28% and 35.59% of the total variance (62.87%), respectively. The hierarchical cluster analysis of the quality characteristics of seasonal samples, the samples were divided into three groups: spring cabbage group, summer cabbage group and fall and winter cabbage group.
Atopic dermatitis (AD) is a common chronic inflammatory disease associated with a cutaneous hypersensitivity reaction to an allergen. Although the incidence of AD is increasing these days, therapeutics has yet to be developed for its treatment. The aim of this study was conducted in order to compare and investigate the characteristic between the Castanea crenata inner shell extract (CS) and the Castanea crenata inner shell extract fermented by Lactobacillus bifermentans (FCS) for an anti-atopic medication. The total polyphenol and flavonoid contents were similar to CS and FCS. In the DPPH and superoxide anion radical scavenging, the CS and FCS had the potential for antioxidant activities. Both of them did not exhibit cytotoxicity to HS68 cells. The evaluation of the anti-inflammatory activity in Raw264.7 cells demonstrated that the FCS has inhibited the LPS-induced production of nitric oxide as compared to the CS. The anti-atopic dermatitis test was done through the induction of DNCB in AD hairless mice. The FCS has inhibited the development of the atopic dermatitis-like skin lesion by transdermal water loss, melanin and erythema of the skin as compared to the CS. Moreover, the pro-inflammatory cytokine IL-$1{\beta}$ and TNF-${\alpha}$ production in hairless mice were inhibited by the FCS treatment. It indicates that the fermentation of the Castanea crenata inner shell has the potential for the treatment of atopic dermatitis.
