This study was designed to identify and characterize the mechanism of macrophage activation by AAP, an acidic polysaccharide fraction isolated from the roots of Angelica sinensis (Oliv.) Diels. As a result, AAP significantly enhanced nitric oxide (NO) production and cellular lysosomal enzyme activity in murine peritoneal macrophages in vitro and in vivo. Furthermore, L-NAME, a specific inhibitor of inducible nitric oxide synthase (iNOS), effectively suppressed AAP-induced NO generation in macrophages, indicating that AAP stimulated macrophages to produce NO through the induction of iNOS gene expression and the result was further confirmed by the experiment of the increase of AAP-induced iNOS transcription in a dose-dependent manner. To further investigate, AAP was shown to strongly augment toll-like receptor 4 (TLR4) mRNA expression and the pretreatment of macrophages with anti-TLR4 antibody significantly blocked AAP-induced NO release and the increase of iNOS activity, and tumor necrosis factor-$\alpha$ (TNF-$\alpha$) secretion.

Purpose: Health care professionals represent an immediately available resource to promote smoking cessation. However, the content in smoking cessation intervention courses in most institutions is insufficiently covered due to the limited number of class hours. The purpose of this study was to develop a comprehensive tobacco cessation-web-based, multimedia, educational program for a range of medical professionals. Methods: Based on Jung's Teaching and Learning Structure Plan Model, a development process was proposed comprising four stages: (1) analysis, (2) planning, (3) production, and (4) operation/evaluation. The effectiveness of the program was tested using quasi-experimental design, and the participants in experimental group were required to complete the program. Changes in the level of knowledge and attitude were measured. Results: The educational program developed includes nine topics and 26 sub-topics. A total of 180 storyboards, 15 videos, and 27 pictures were made. After the education, the level of knowledge was significantly increased in the experimental group. Conclusion: This web-based program can be recommended as a potential medium for health care professionals to use in counseling smoking cessation. The study findings also indicated that the program may be either offered as a teaching aid or utilized concurrently with lectures for students studying health care-related topics.

College is a component of local community, which is not separated from the community, seeks the local development through the extension of opportunity for the local students to enter higher schools, improvement of local culture and environment, extension of production education, research on local community, supply of side job manpower and lecture attendance system and affects the local community with the increase of young population. It is found that after the College is founded in the research area, the whole image of physical and psychological evolution of College according to the change factors like the change of use of neighboring regions and business items is relatively active, has the connection to the region and shows the strong continuous image. Accordingly, College must seek the mutually organic relationship which local community and be a foundation for the local development by leading to the formation of neighboring region around campus.

The aims of this study were three. First, to examine the degree of deviation from dictionary prescribed symbols and actual speech made by American English speakers. Second, to measure the frequency of vowel and consonant production of American English speakers. And third, to investigate gender differences in the segmental sounds in a speech corpus. The Buckeye Speech Corpus was recorded by forty American male and female subjects for one hour per subject. The vowels and consonants in both the phonemic and phonetic transcriptions were extracted from the original files of the corpus and their frequencies were obtained using codes of a free software R. Results were as follows: Firstly, the American English speakers produced a reduced number of vowels and consonants in daily conversation. The reduction rate from the dictionary transcriptions to the actual transcriptions was around 38.2%. Secondly, the American English speakers used more front high and back low vowels while three-fourths of the consonants accounted for stops, fricatives, and nasals. This indicates that the segmental inventory has nonlinear frequency distribution in the speech corpus. Thirdly, the two gender groups produced vowels and consonants similarly even though there were a few noticeable differences in their speech. From these results we propose that English teachers consider pronunciation education reflecting the actual speech sounds and that linguists find a way to establish unmarked segmentals from speech corpora.

The purpose of this study was to make ramyon from Korean cultured wheat by adding with hot water extract powder from safflower seed in order to add the value of it. The cooking quality, instrumental texture and sensory characteristics of ramyon were analyzed. The ramyons with 0.1%, 0.3%, 0.5%, and 0.7% of hot water extract powder(HEP) from safflower seed, control, and those with 3% and 5% of dried powder(DP) from safflower seed were compared. The yield of HEP was 7.8%. Lightness, redness, Max. weight, strength, hardness, adhesiveness, cohesiveness and springiness were measured. As the amounts of HEP and DP was increasing, ramyons smelled stronger and was getting harder and chewier, while became less transparent and had no difference in elasticity and adhesiveness. In overall acceptability, both control and ramyon with HEP had similar points. From three important factors, appearance, color and smell to make ramyon more acceptable, addition of 0.3～0.5% of hot water extract powder from safflower seed was found to be the best. However, further studies on smells are needed to make processed foodstuffs with safflower seed.

This study identified the characteristic and meaning of flow experience through the experiences related to fashion models' role performance; subsequently, the following findings were obtained. First, fashion models' flow experience could be divided into characteristics such as temporality, spatiality, relationality, physicalness and pleasure. Second, the process of this flow experience ultimately led to the complete moment. The complete moment can be said to be the aesthetic experience that provides both the meaningful experience and the aesthetic pleasure; it is the experiential knowledge at the dimension of mysterious integration that their body and mind are integrated into one. The beauty that fashion models exercise at the aspect of this aesthetic experience is that of performance and is an individual physical movement where they perceive their role and exercise their inner ability to express their costume most beautifully. Accordingly, the beauty of performance can be said to mean that the fashion show was successfully held by inducing both the performer and the audience into an aesthetic response. The process of specialized planning and preparation is required for fashion models to exercise the beauty of performance at the complete movement reached through flow experience and a successful fashion show. Diverse elements of the fashion show should be more organically constituted through such a process. Fashion models should exert efforts to embody acts such as walking, posing and turning through the performance of their excellent role as well as develop a training program to complete it.

The genetic polymorphism and relationships of Muscovy, Cherry Valley Meat ducks, Partridge ducks and their crossbreds $F_1$ and $F_2$, respectively, were studied using a random amplified polymorphic DNA (RAPD) technique. The results showed that RAPD markers were effective for the analysis of genetic relationships among ducks. Amplification with 20-primers gave 760 reproducible amplified fragments. The percentage of polymorphic marker band was 74.70%, which indicates that the RAPD technique had higher efficiency of polymorphism detection and sensitivity in studying the genetic variations among ducks and showed that the genetic polymorphism was abundant between two species of duck populations. The average index of genetic distance in hybrid $F_2$ was 0.2341 and higher than that of its parents, which indicates that the genetic diversity was improved by crossbreeding with Muscovy.

Asexual benthic polyp reproduction plays a major role in the jellyfish bloom. Recent studies found that temperature is the most important factor to regulate the budding rate of the polyps. We established a simple dynamic model to count the number of polyps depending on the variation of temperature with two data sets from different places. The population of polyps was counted through the budding rate and the number of budding times by Fibonacci sequence. It is assumed that the budding rate depends on the temperature only. The budding rate of the asexual reproduction shows very sensitive to the distribution of the seawater temperature. The model was tested to the temperature data of Ansan located in the west sea of Korea. The results indicate that this model can be useful to predict the blooms of Aurelia aurita polyps, which may have considerable influence on the bloom of medusa. The shape of temperature curve plays a key role in the predicting the bloom of Aurelia aurita polyps.

In the production of industrial fabric, it needs automatic real-time system to detect defects on the fabric for assuring the defect-free products flow to the market. At present, many visual-based methods are designed for detecting the fabric defects, but they usually lead to high false alarm. Base on this reason, we propose a Sobel operator combined with patch statistics (SOPS) algorithm for defects detection. First, we describe the defect detection model. mean filter is applied to preprocess the acquired image. Then, Sobel operator (SO) is applied to deal with the defect image, and we can get a coarse binary image. Finally, the binary image can be divided into many patches. For a given patch, a threshold is used to decide whether the patch is defect-free or not. Finally, a new image will be reconstructed, and we did a loop for the reconstructed image to suppress defects noise. Experiments show that the proposed SOPS algorithm is effective.
