Objectives : The purpose of this study was to examine the relation between stress and temporomandibular disorder(TMD) of first the child. Methods : 500(the first child -250, non first child -250) high school students living in Jecheon city, form November 4th to 5th 2009, were the subjects of this questionnaire. The questionnaire was made up of three contests: sociodemographic characteristic, symptom & dysfunction of TMD and stress of high school students. The data were analyzed by chi-square test, two sample t-test and Pearson correlation. Results : Only 443(the first child -209, non first child - 234) students were evaluated due to inadequate responses. The obtain results was as follow. 1. Subjective symptom of TMD reported by 443 students were joint sound(63.5%), pain on chewing(55.1%), pain on opening the mouth(55.1%). 2. Analysis of subjective symptom of TMD showed the first child group was statistical significantly higher on joint sounds and TMJ pain than non first child group(<0.05). 3. Analysis of bad habit and dysfunction showed the first child group was statistical significantly higher on clenching of the teeth, difficulties of bite, headache than non first child group(<0.05). 4. Analysis of stress showed the first child group was statistical significantly higher on stress with parents than non first child. especially on marks and disagreement(<0.05). 5. Stress were partly related to subject symptom of TMD(<0.05, <0.01). 6. Analysis of relation stress and bad habit & dysfunction showed stress were partly related to bad habit & dysfunction(<0.05, <0.01). 7. bad habit were partly related to TMD(<0.05, <0.01). Conclusions : The first child stress and symptom of TMD were higher than non-first child, also stress and symptom of TMD was positively associated. therefore management of the first child' stress is necessary and related study is necessary in the future.

In images degraded by bad weather, edges representing object boundaries become weak and faint. In this paper we present an image enhancement method, which increases image visibility by making edges as clear as possible. First, we choose edge candidate regions by finding local maxima and minima in an image intensity field, and then build a histogram using image intensities of pixels located at the two sides of candidate edges. Second, we decompose this histogram into multiple modes, which are determined by local minima in the histogram. Once modes are computed, we find modes connected by edges in the image intensity field and build link chains of connected modes. Finally we choose the longest link chain of modes and make the distances between every connected modes as large as possible. The darkest mode and the brightest mode should be within the image intensity range. This stretch makes edges clear and increases image visibility. Experiments show that the proposed method real-time enhances images degraded by bad weather as good as well known time-consuming methods.

Objectives : We investigated to find the relationship between single-nucleotide polymorphism (SNP) of IL4R, IL-10 and bee venom therapy efficacy in patients with RA treated with bee venom for 8 weeks. Methods : Korean RA patients (n=114) and healthy subjects (n=109) were included in this prospective study. Korean bee venom was dissolved in saline (diluted 1:3000) and administrated into acupuncture points. Bee venom therapy was applied twice a week and continued for 8 weeks. The clinical response was evaluated using various assessments before and after treatment. Disease severity was measured by determining the number of tender joints and swollen joints. Laboratory studies included ESR, CRP, and rheumatoid factor. Genotyping for IL-4R and IL-10 polymorphism was done by pyrosequencing analysis. Results : 1. In IL4R genotypes, there was significant difference between RA ptitients tind controls group. 2. In IL4R genotypes, there was significant difference among Good, Mild and Bad responders to in RA patients, but in the frequency of alleles and carriers, there were no significant difference. 3. There was no significant difference between RA patients and controls group in IL-10 gene genotypes. 4. In IL-10 genotypes, there was no significant difference among Good, Mild and Bad responders to in RA patients. 5. There was no significant difference in the improvement of ESR, CRP and KHAQ scores after bee venom therapy in RA patients among the IL4R or IL-10 genotypes. Conclusions : In IL-4R genotypes, there was significant difference between RA patients and control group, and among Good, Mild and Bad responders in RA patients. However, in IL-10 genotypes, there was no significant difference between RA patients and controls group and among Good, Mild and Bad responders in RA patients.

PURPOSES : Visibility of lanes on the road improves as retro-reflectivity rises. This helps reduce traffic accidents at nighttime or in bad weather. This study aimed to evaluate the effects of improved visibility on reduction of traffic accidents when the color of the lane in the median of the highway was changed from yellow to white. METHODS : In order to evaluate the accident reduction effect of the white left shoulder line, Hauer (1997)'s Comparison-Group method was chosen as an analysis methodology. The JungBu-2 highway, which is equipped with the white left shoulder line and is in trial operation, was chosen as a target for analysis. Data of accidents for 10 months before and after installation was collected and analyzed. In addition to the number of accidents, the types of accidents were classified into nighttime accidents, accidents in bad weather, and median collisions. The accident reduction effect of improved visibility of lanes was analyzed. RESULTS : The analysis' finding showed that installation of the white left shoulder line decreased the number of accidents by 28%. Moreover, improvement in visibility was effective in reducing nighttime accidents by 67.63%, accidents in bad weather by 55.19%, and median collisions by 48.55%. CONCLUSIONS : Based on the analysis' results in this study, it was concluded that white left shoulder line on the freeway contributed to reduce traffic accidents, especially nighttime accidents, accidents in bad weather, and median collisions.

We attempted to modulate the overall protein expression rate through the addition of a repressor against the araBAD promoter system of Escherichia coli, in which glucose was used as a repressor. Therefore, 0.5% L-arabinose was initially contained as an inducer in culture medium, and either 2% glucose or 2% glycerol was used as a carbon source, and it was found that the expression of recombinant interferon-${\alpha}$ could be observed at the beginning of the batch culture when glycerol was used as a carbon source. However, when glucose was used, the initiation of recombinant interferon-${\alpha}$ expression was delayed compared with that when glycerol was used. Furthermore, when the addition of 0.5% glucose was carried out once or twice after 0.5% L-arabinose induction during DO-stat fed-batch culture, the distributions of soluble and insoluble recombinant interferon-${\alpha}$ were modulated. When glucose was not added after the induction of L-arabinose, all of the expressed recombinant interferon-${\alpha}$ formed an inclusion body during the later half of culturing. However, when glucose was added after induction, the expressed recombinant interferon-${\alpha}$ did not all form an inclusion body, and about half of the total recombinant interferon-${\alpha}$ was expressed in a soluble form. It was deduced that the addition of glucose after the induction of L-arabinose might lower the cAMP level, and thus, CAP (catabolite activator protein) might not be activated. The transcription rate of recombinant interferon-${\alpha}$ in the araBAD promoter system might be delayed by the partial repression. This inhibition of the transcription rate probably resulted in more soluble interferon-${\alpha}$ expression caused by the reduction of the protein synthesis rate.

The purpose of this study(Part I) was to provide the guidance in more objective and proper clothing design and wearing rule to make good image making by analysis of fashion sensibilities about adult women's town wear in unlimited circumstance. The specific objectives were; 1)to investigate about fashion sensibility of women's town wear at season 2)to investigate about fashion sensibilities of women's town wear of properties which are age, marriage or not, job, average income per month, and schooling. 3)to compare fashion sensibility between Good and Bad women's town wear. The collected photos at shopping mall, department stores, and churches(S/S, F/W:2004.4.28~2005.5.1) were prepared removing face and background that can affect in estimator and attached on gray board. To investigate fashion sensibilities, the stimulus were 80 photos('good':40, 'Bad':40). The questionnaire consisted of bi-polar 25 pairs adjective scale of fashion sensibilities was distributed 60 female(20's~40's) living in Busan. The data were analyzed by t-test, ANOVA, and Scheffe. The results of this study are summarized as follows; For fashion sensibilities at 'Good' and 'Bad' wear, the variances(season, age, marriage or not, job, average income per month, and schooling) are important. Especially, the fashion sensibility at 30's women are very unique and importance age zone to catch both young women's fashion sensibility and old women's fashion sensibility, Through that age zone, we could read women's various fashion sensibility and prospect complicate consumers' fashion mind. This study result will be utilized in the clothing design for target age zone of women's town wear, database of wearing rule and good image making, and planning fashion marketing strategies.

Generally, the Internet Address Resources Act is intended to protect the public from acts of Internet "cybersquatting", a term used to describe the bad faith, abusive registration of Internet domain names. In determining whether a person has a bad faith intent, a court may consider factors such as, (1) the trademark or other intellectual property rights of the person, if any, in the domain name, (2) the extent to which the domain name consists of the legal name of the person or a name that is otherwise commonly used to identify that person, (3) the person's prior use, if any, of the domain name in connection with the bona fide offering of any goods or services, (4) the person's bona fide noncommercial or fair use of the mark in a site accessible under the domain name, (5) the person's intent to divert consumers from the mark owner's online location to a site accessible under the domain name that could harm the goodwill represented by the mark, either for commercial gain or with the intent to tarnish or disparage the mark, by creating a likelihood of confusion as to the source, sponsorship, affiliation, or endorsement of the site, (6) the person's offer to transfer, sell, or otherwise assign the domain name to the mark owner or any third party for financial gain without having used, or having an intent to use, the domain name in the bona fide offering of any goods or services, or the person's prior conduct indicating a pattern of such conduct.

Present research was carried out on the level of exploration to verify that good luck increases probabilistic framing effect but bad luck decrease the effect. And we organized an experiment that designed experience of luck (good luck vs. bad luck vs. control) ${\times}$ probabilistic frame (high vs. low) and observed whether people response based on probabilistic frame or not. As a result, we observed the two-way interaction where experience of good luck increased probabilistic framing effect, while experience of bad luck decreased the effect (Figure 1). We expect to see more studies of contextual framing effect besides probabilistic frame (e.g., positive vs. negative; loss related to context vs. loss irrelevant to context).
