  • In this study, we fabricated a fiber-optic phantom dosimeter by arraying square type of plastic optical fibers in a PMMA phantom for measuring relative depth doses of therapeutic photon beams. To minimize the cross-talk between fiber-optic dosimeters, we selected appropriate septum by measuring leaked scintillating lights according to the various kinds of septa. In addition, we measured percentage depth doses of 6, 15 MV photon beams using a fiber-optic phantom dosimeter.

  • Purpose: The purpose of this study was to compare health literacy levels of Asian immigrant women and factors associated with health literacy focusing on Korean-Chinese and other Asian immigrants in Korea. Methods: Data were drawn from 258 immigrant women, comprising 56 Korean-Chinese and 202 other immigrants from the Philippines, Vietnam, Japan, Cambodia, Thailand, Uzbekistan, Taiwan, and Han-Chinese. The Rapid Estimate of Adult Literacy in Medicine - Short Form (REALM-SF) was used to assess health literacy, which consisted of seven medical words in Korean (behavior, exercise, menopause, rectal, antibiotics, anemia, and jaundice). Data analysis was performed using descriptive statistics, t-test, ANOVA with $Sch{\acute{e}}ffe$ post hoc test, and hierarchical regression. Results: Korean-Chinese women showed significantly higher levels of health literacy ($M=6.41{\pm}1.07$), compared to their other immigrant counterparts ($M=4.55{\pm}2.15$). While Korean-Chinese women with longer time since immigration (p=.048) reported higher health literacy, for other immigrants, those living with children (p<.001), longer time since immigration (p=.011), and greater Korean language proficiency (p=.004) showed an association with higher health literacy. Conclusion: When providing health care services and health education, health care professionals should consider differences in levels of health literacy and factors associated with health literacy among Korean Chinese and other immigrants.

  • Purpose: The purpose of this study was to obtain data that can be utilized in the planning of oral health education plan, by surveying the correlation between oral health knowledge, attitude, and behavior among high grade students elementary school in some regions of the metropolitan. Methods: The subject of this study through the survey of the recognition of the oral health, a questionnaire survey was conducted for 548 male and female students who were in the 4th, 5th, 6th grade of elementary school in some regions of the metropolitan. Statistical analysis was conducted using the SPSS 12.0 with t-test, ANOVA, and correlation. Results: Knowledge of oral health was very high. Correct attitudes and positive behavior were indicated. There was a significant difference in oral health knowledge according to school year and parents' dental condition(P<.05). The student one recording oral health behavior degree where the oral health knowledge is high appears highly, considers statistically the difference which it was visible. Positive correlation was significantly observed among oral health knowledge, attitudes, and behavior. Especially, attitudes and toothbrush method were highly correlated(r=.853). Conclusion: Oral health program through the elementary school students and their parents for the development of proper oral health care education programs continue to be made should be considered.

  • This article concerns the labeling guideline for health benefits of livestock products. In recent years, livestock products with health benefits have emerged as a key market for livestock product industries. However, the current labeling regulation for functional foods severely prohibits livestock product industries from attaching most of the health benefits claims to the products. Also, manufacturers have some difficulties in labeling the health benefits of certain livestock products because of a lack of guidelines on health benefit claims for livestock products. Therefore, some livestock product industries and scientists have strongly demanded a revision of labeling regulation, Appended Chart No. 14 provided by Article 52 (2) of Enforcement Regulation of the Processing of Livestock Products Act, so they could mark the health benefits on their products. To support the 'revision of labeling regulation', the goals of this article were as follows; 1) to assess the current situation on nutrition labeling and nutrition claims on foods, 2) to determine the current situation on health claim regulatory systems used in foreign countries (CODEX, USA, Japan, EU, and Australia/New Zealand), 3) to assess the current situation on the health claim or health benefit claim regulations for functional foods, conventional foods, and livestock products in Korea, and 4) to determine the need for complement in health benefit claim for livestock products. In conclusion, guidelines for the use of health benefit claims on livestock products should be prepared as soon as possible and the guidelines should be viable and easy for manufacturers and control authorities to understand. Also, nutrient profiles should be developed to identify whether the livestock products are eligible to bear health benefit claims and to help consumers make the right choices.

  • In Italy, buffalo mozzarella is a largely sold and consumed dairy product. The fraudulent adulteration of buffalo milk with cheaper and more available milk of other species is very frequent. In the present study, Fourier transform infrared spectroscopy (FTIR), in combination with multivariate analysis by partial least square (PLS) regression, was applied to quantitatively detect the adulteration of buffalo milk with cow milk by using a fully automatic equipment dedicated to the routine analysis of the milk composition. To enhance the heterogeneity, cow and buffalo bulk milk was collected for a period of over three years from different dairy farms. A total of 119 samples were used for the analysis to generate 17 different concentrations of buffalo-cow milk mixtures. This procedure was used to enhance variability and to properly randomize the trials. The obtained calibration model showed an R2 ≥ 0.99 (R2 cal. = 0.99861; root mean square error of cross-validation [RMSEC] = 2.04; R2 val. = 0.99803; root mean square error of prediction [RMSEP] = 2.84; root mean square error of cross-validation [RMSECV] = 2.44) suggesting that this method could be successfully applied in the routine analysis of buffalo milk composition, providing rapid screening for possible adulteration with cow's milk at no additional cost.

  • Soy proteins have been extensively studied because of its multiple health benefits. However, the effects of soy proteins on human cervical cancer cells are still unclear. Therefore, this study investigated the effects of soy proteins on HeLa cells and human fibroblasts by using soybean peptides (SPs). SPs selectively increased the generation of reactive oxygen species and apoptosis in HeLa cells but not in fibroblasts. In addition, SPs suppressed the migration of HeLa cells. Although the molecular mechanisms underlying the effects of SPs on human cervical cancer cells need to be investigated further, our findings provide insights on the therapeutic effects of soy protein on cervical cancer.
