Purpose: This study was conducted to examine the level of physical activities at time points of pre-illness and current treatment, and the differences in body mass index (BMI), anxiety, depression and fatigue according to their physical activity in cancer patients undergoing chemotherapy. Methods: The survey was used with 126 cancer patients undergoing daily chemotherapy at injection room, cancer clinic of C University Hospital in G city. Data were collected from June to September, 2009 using a structured questionnaire. The data were analyzed by descriptive statistics, chi-square, Fisher's exact test and t-test using SPSS/WIN15.0. Results: The significant increase in physical activity was reported from pre-illness to the time in treatment (${\chi}^2$=69.027, p<.001). The anxiety level of the group with increased physical activity was significantly lower than those who did not (t=-2.218, p =.028). There were no significant differences in BMI, depression, and fatigue according to physical activity. Conclusion: The level of physical activity was significantly associated with the anxiety level of the cancer patients undergoing chemotherapy. Cancer patients should been encouraged regular physical activity during chemotherapy treatment. And an appropriative nursing intervention should be established in order to motivate cancer patients to increase physical activity.

Objective: This study aimed to explore the experience and meaning of pre-service early childhood teachers who practiced health promoting activities for themselves. Methods: Research participants were 115 pre-service early childhood teachers enrolled in the health education for children course at one college in G region. The reports of activity records of their eight-week long health promotion activities were collected as qualitative data followed by content analysis being implemented. Results: First, the experience of the health promoting activities the participants took part in was categorized into 'Early phase of experience: A mix of worries and anticipation, and success and failure', 'Mid phase of experience: Being motivated by physical changes and records', and 'Late phase of experience: Continuous execution through habituation.' Second, the meaning of health promotion activities the participants took part in was categorized into 'A great opportunity for introspection', 'A meaningful start of college life', and 'A valuable chance to consider desirable roles of a teacher for early childhood health education.' Conclusion/Implications: The results of this study suggest that pre-service early childhood teachers should pay close attention to their health management, and that contents that emphasize the importance of teachers' health should be included in health education.

IL-33 is a member of the IL-1 cytokine family and plays a role in the host defense against bacteria, viruses, and fungi. In this study, we investigated the function of IL-33 and its receptor in in vitro macrophage responses to Candida albicans. Our results demonstrate that pre-sensitization of isolated peritoneal macrophages with IL-33 enhanced their pro-inflammatory cytokine production and phagocytic activity in response to C. albicans. These macrophage activities were entirely dependent on the ST2-MyD88 signaling pathway. In addition, pre-sensitization with IL-33 also increased ROS production and the subsequent killing ability of macrophages following C. albicans challenge. These results indicate that IL-33 may increase anti-fungal activity against Candida through macrophage-mediated resistance mechanisms.

This study was intended to investigate the effects of nutritional, physical and environmental conditions on the bone status of 102 pre and post menopausal women living in Ulsan area. The results of this study are summarized as follows : when subjects were classified into two groups by bone status, there were significant differences in age, calcium index, serum estrogen and physical activity between two groups. Average daily calcium intake of subjects was 682.9 (149.2)mg, which is almost same as RDA, but 41.1% of the subjects consumed calcium below RDA. Calcium index(p<0.05), serum estrogen(p<0.001), physical activity(p<0.001) of poor bone group were significantly lower than those of good bone group. Although there was not a significant difference between bone status and other influential factors, such as family type, skip meal, alcohol drinking, smoking and BMI, each has been shown to have an effect, if slight, on the bone status.

Antioxidative effects of rice hull extracts pre-treatment with various organic acids were evaluated. After incubating rice hull in 50 mM of five different organic acid solutions (acetic, citric, lactic, phosphoric, and tartaric acid) for 18 hours at room temperature, hydrothermal treatment at $121^{\circ}C$ for 30 min was carried out. Antioxidant activity of the rice hull extract was evaluated by determining total phenol contents (TPC), DPPH radical scavenging activity (RSA), reducing power (RP), and ABTS RSA. Pre-treatment with 50 mM phosphoric acid significantly increased TPC, DPPH RSA, and RP, while it decreased ABTS RSA. The effect of phosphoric acid concentration was also determined. TPC and DPPH RSA of rice hull extract increased with concentration of pre-treated phosphoric acid; in contrast, RP showed the reverse pattern. The results indicated that pre-treatment of rice hull with organic acid was very effective for increasing phenolic compounds and antioxidant activity of rice hull extract.

As a food ingredient, the extract has been proven of its antioxidant properties and safe to be consumed. It's increased antioxidant activity was evaluated by comparing its activity to the complex extract of fruits and vegetables, which is known to exhibit both antioxidant and physiological activities. In this experiment, after pre-heat treatment process, the increased antioxidant extract showed 41% of DPPH radical scavenging activity. The remarkable antioxidant activity of the produced extract will become useful in creating cosmetic or health products.

The purpose of this study is to empirically compare statistical models for pre-service teachers' help networks. We identified similarities and differences based on the results of the binary and valued ERGM. Research questions are as follows: First, what are the similarities of factors influencing the binary/valued help network for pre-service teachers? Second, what are differences of factors influencing the binary/valued help network for pre-service teachers? We measured 42 pre-service teachers with focus on their help and friend networks, happiness, and personal characteristics. Results indicated that, first, the similar factors influencing the binary and valued help network of pre-service teachers were local dependencies (reciprocity, transitivity), similarity (major, gender), activity (early childhood education, negative emotion), popularity (early childhood education) and multiplicity (friend network). Second, the difference between factors affecting pre-service teacher's binary and valued help network was the effect of activity (physical education) and popularity (GPA, negative emotion). Based on these findings, we presented implications.

Pre-pentration activity of Pyricularia oryzae Cav. from the stage of conidia germination to appressorium formation was examined on rice leaf epidermis under light and scanning electron microscopes to determine the causes· for differences in blast susceptibility between plants grown under three different soil moisture conditions in the greenhouse. No significant differences were found in the external shape of leaf epidermal cells including bulliform cells between plants grown under different soil moisture conditions. Growth and orientation of germ tube and morphology and size of appressorium of P. oryzae did not vary with soil moisture treatment. Site of appressorium formation was consistent over soil moisture treatment with the highest frequency of bulliform cell $(35\~48\%)$, followed by short cell $(19\~27\%)$, and long and guard cells $(13\~20\%)$. No appressorium was formed on trichome. This result suggests that the observed differences in blast susceptibility between plants grown under different soil moisture conditions were not due to the differences in the pre-pentration activity of P. oryzae on those plants.

This study examines the effects of Evening primrose on colors, color fastness, and the antimicrobial activity of dyed fabrics. The results are as follows. The dyeing conditions of Evening primrose on cotton and mercerized cotton were optimized at $50^{\circ}C$, 60 minutes, and 200% (o.w.f.). In addition, Evening primrose dyeing on silk was determined at $90^{\circ}C$, 60 minutes and 200% (o.w.f.). The pre-mordant concentration of chemicals of cotton, mercerized cotton and silk was optimized at 1% (o.w.f.). The post-mordant concentration on mercerized cotton, silk and cotton was determined at 1% (o.w.f.) and 3% (o.w.f.), respectively. The mordant methods (such as pre-mordant and post-mordant) were slightly affected on the hue of dye-fabrics. Wet cleaning fastness of cotton was improved by post-mordant; otherwise, the wet cleaning fastness of mercerized cotton and silk was improved by a pre-mordant. The dry cleaning fastness of cotton and silk was excellent regardless of mordant methods. The dry cleaning fastness of mercerized cotton was improved by a post-mordant compared to a pre-mordant. The antimicrobial activity of Evening primrose-dyed fabrics was shown at 99.9%. The excellent antimicrobial activity of dyed fabrics remained after the mordant as well as wet and dry cleaning.
