Costume plays have been of interest to young people in the recent years. The much increased interest in costume plays has prompted many researchers to verify the behavior characteristics of costume players Despite the importance of the costume play, there has been no systematic study of it. The purpose of this study is to demonstrate the influence of life style on behavior characteristics of the costume player. The subjects of this study were members of the web sits(wwwcosmakercom). A total of 155 subjects responded to the questionnaires and the 143 responses were used for further data analysis. The data was analyzed by factor analysis, cluster analysis, and one-way ANOVA. These were the results of the stud: First, costume player groups are classified into three sub-dimensions: other people-oriented, show-off oriented, and exclusive ego oriented. Second, the behavior characteristics of costume player are significantly shown among those groups.

The objective of this thesis is to investigate the influence of the initial residual stress on the fatigue crack growth after the distribution of the initial residual stress is measured when the crack is growing from the compressive residual stress to the tensile residual stress field. In the case of as welded material, respective of load ratio, the span of the fatigue is the shortest in base metal, while in weld metal and HAZ, the crack growth was retarded due to the effect of the compressive residual stress at the crack tip as well as the span of the crack is longer than base metal. In region II that is in stable growth state of the fatigue crack, da/dN=C(ΔK)^m of power law was satisfied. Also, it was considered that the value of m is not affected by residual stress. Superimposing welding residual stress intensity factor K_res on ΔK, the value of ΔK_eff calculated was lower than ΔK in the same value of da/dN, while the ΔK_eff is almost the same at the high ΔK.

This study was conducted to reduce children`s fat intake and to establish healthy dietary lifestyles. To achieve these goals, we searched, collected, and analyzed the materials related to the fat education, based on which the research personnel-professors and graduate students in nutrition and child education and elementary school teachers- discussed to figure out major topics, objectives, and detailed contents and activities appropriate for fat intake reduction. We also organized an advisory committee composed of 15 professionals in related fields to discuss the adequacy and validity of the specific contents. Finally, we systematically organized the contents and developed children`s textbooks and teacher`s guidebooks. Considering the different cognitive development stages of junior and senior elementary students we developed two different textbooks for each of them which are easy to read and understand, fun to play with lots of activities, and designed to practice into daily life. The contents cover three major topics-the concept of lipid, lipid in food, lipid in life and are composed of 6 units in total. To help teachers understand and and to instruct, teacher`s guidebooks contain an overview of the education, specific information and practical guidelines for each class. We developed these education materials with the aim of lowering children`s fat consumption and eventually promoting their health welfare; hopefully we expect these materials would be useful for children`s nutritional education in the field.

Diapause duration of Paratlanticus ussuriensis is prolonged as an egg that enter both initial and final diapause stgaes. Environmental conditions, such as temperature, can modify the duration of initial diapause. Eggs enter initial diapause at 20℃, but continued early embryonic development at 30℃. Final diapause at a fully developed embryonic stage is obligatory regardless of temperature conditions. To determine temperature effects on initial diapause mechanism of P. ussuriensis eggs, we compared weights, DNA and RNA amounts of eggs incubated at either 20℃ or 30℃ for 50 days after oviposition. We identified small heat shock protein (shsp), heat shock protein 90 (hsp90) and three heat shock protein 70 (hsp70a, hap70b, hsp70c) genes of P. ussuriensis and determined those expression levels at different temperature conditions. The levels of shsp, hsp70a, hsp70b and hsp90 was not detectable until 20 days after oviposition at both temperature conditions, but highly increased at 50 and 60 days when incubated at 30℃. In contrast, hsp70c level was rapidly peaked at 20 days after oviposition, which is the time of initial diapause entrance. We analysis of temperature sensitivity of P. ussuriensis eggs. Hsp70a is expressed after the first cold treatment of mature eggs. Hsp70b is highly expressed just before hatching. Both shsp and hsp70c was highly expressed at the heat shock condition into immature egg stage. Our results suggest that high temperature breakdown initial diapause and one hsp gene, such as hsp70c, may be involved into the mechanism of initial diapause of P. ussuriensis eggs.

<P>During embryonic and cancer development, the Hedgehog family of proteins, including Sonic Hedgehog, play an important role by relieving the inhibition of Smo by Ptc, thus activating the Smo signaling cascade. Recently, a purine compound, purmorphamine, has been reported to target the Hedgehog signaling pathway by interacting with Smo. Interestingly, both Sonic Hedgehog and purmorphamine were found to promote the osteogenic differentiation of mouse chondroprogenitor cells. However, there is insufficient information as to how the activation of this seemingly unrelated signaling pathway, either by Sonic Hedgehog or purmorphamine, contributes to osteogenesis. Using alkaline phosphatase assays, we screened 125 purmorphamine derivatives from the Korea Chemical Bank for effects on the differentiation of preosteoblast C2C12 cells. Here, we report that two purine derivatives modulate ALP activity as well as the expression of genes whose expression is known or suggested to be involved in osteogenesis.</P>

To find prognostic factors for intensive care unit (ICU) days in patients with acute eosinophilic pneumonia (AEP). Method: Consecutive patients who were diagnosed as AEP were enrolled. Clinical parameters of patients were collected. The diagnosis and treatment was according to standardized protocol. Result: From May 2007 to October 2010, 138 patients were diagnosed. Ninety-eight percent of patients were smoking related. Mean age was 20.21±0.09 (mean±SEM) years. The initial PaO2/FiO2 (PF) ratio was 281.94±6.22. Peripheral blood (PB) eosinophil was 4.37±0.39 % and bronchoalveolar lavage (BAL) eosinophil was 44.98±1.23 %. C-reactive protein (CRP) level was 9.64±0.46 mg/dL. Radiologic findings were ground glass opacity (97.1 %), air-space consolidation (37.0 %), poorly defined centrilobular nodules (51.4 %), interlobular septal thickening (68.1 %), thickening of bronchovascular bundle (17.4 %), and pleural effusion (88.4 %). One hundred nine (79.0 %) patients were admitted to the ICU, and the mean duration of ICU stay was 2.50±0.13 days. Correlation between ICU days and other clinical parameters were examined. ICU days were significantly correlated with the PF ratio (r=-0.287, p=0.002) and CRP (r=0.361, p<0.0001). However other clinical parameters (BAL eosinophil, PB eosinophil, and age) were not correlated with ICU days. Also, there was no significant difference in ICU days according to radiologic findings. In a multivariable linear logistic regression analysis, PF ratio and CRP level were significant prognostic factors to determine ICU days. Conclusion: PF ratio and CRP were prognostic factors for predicting ICU days in patients with AEP. Further study about the prognostic factor in patients with AEP is needed.

Background Facial laceration is the most common injury encountered in the emergency room in the plastic surgery field, and optimal treatment is important. However, few authors have investigated this injury in all age groups or performed follow-up visit after repair. In the present study, the medical records of patients with lacerations in the facial area and underwent primary repair in an emergency room over a 2-year period were reviewed and analyzed. Methods Medical records of 3,234 patients with lacerations in facial area and underwent primary repair in an emergency room between March 2011 and February 2013 were reviewed and identified. Results All the 3,234 patients were evaluated, whose ratio of men to women was 2.65 to 1. The forehead was the most common region affected and a slip down was the most common mechanism of injury. In terms of monthly distribution, May had the highest percentage. 1,566 patients received follow-up managements, and 58 patients experienced complications. The average days of follow-up were 9.8. Conclusions Proportion of male adolescents was significantly higher than in the other groups. Facial lacerations exhibit a 'T-shaped' facial distribution centered about the forehead. Careful management is necessary if a laceration involves or is located in the oral cavity. We were unable to long term follow-up most patients. Thus, it is necessary to encourage patients and give them proper education for follow-up in enough period.

합병 문제는 정렬된 두 개의 리스트 A=(a₁, a₂,..., a₁)와 B=(b₁, b₂,..., b_m)가 주어질 때, 이 두 리스트를 합병하여 하나의 정렬된 리스트 C=(c₁, c₂,..., c_n), n=l+m,로 만드는 문제이다. 지금까지는 √n×√n 메쉬 상에서 odd-even 합병을 재귀적으로 수행하는 O(√n)시간 합병 알고리즘이 주로 사용되었는데, 이 재귀적 합병 알고리즘은 그 기본정책은 간단하나, 메쉬 상에 구현될 때 라우팅과 같은 복잡한 연산이 필요하게 된다. 따라서 본 논문에서는 간단한 행, 열 연산 만을 사용하여 메쉬 상에서 쉽게 구현가능한 O(√n)시간의 최적 분할 합병 알고리즘을 제안한다.
