H.S. Lee,J.H. Chang,S.K. Ku
European Journal of Histochemistry , 2012, DOI: 10.4081/ejh.2012.e5
Abstract: The regional distribution and quantitative frequency of pancreatic endocrine cells were demonstrated in the Korean golden frog (Rana plancyi chosenica Okada), which is known as a Korean endemic species, for the first time, by immunohistochemical methods using specific mammalian antisera to insulin, glucagon, somatostatin and human pancreatic polypeptide (PP). In the pancreas of the Korean golden frog, all four endocrine cell types were demonstrated. Insulin- and glucagon-positive cells were located in the pancreas as single cells or islet-like clusters with frequencies of 85.90±18.28 and 54.30±8.77/1,000/1,000 cells, respectively. Somatostatin-containing cells were also dispersed in the pancreas as single cells or clusters but in the case of clusters, they are exclusively situated in the marginal regions of insulin- or glucagon-positive cell clusters. Cells stained for somatostatin cell frequency was 15.50±3.10/1000 cells. PP-containing cells were also distributed as single cells or clusters with frequency of 53.40±11.96/1,000 cells. Clusters consisted of PP-positive cells are distributed as a core type and a marginally distributed type. Overall, there were 40.84±3.81% insulin-, 26.02±1.71% glucagon-, 7.63±2.09% somatostatin- and 25.51±3.26% PP-IR cells.

Abstract: brazilian systems for raising bullfrogs (concrete enclosure, concrete enclosure with feed dispenser and shelter, flooded enclosure) do not use enough water to keep temperature stable, and the low rate of water renewal hinders water quality. in this article we propose raising frogs in cages placed in fish ponds having high thermal stability. the experiment consisted in evaluating the productive performance of bullfrogs housed in 1 m3 cages at the densities of 28, 56 or 84 animals/ cage, fed a ration delivered by an automatic dispenser. each pond was 72 m2 large. two fish densities were used (200 or 300 tilapias/pond). the experimental period lasted 105 days for tilapias (may-august) and 60 days for frogs (july-august). no significant differences among densities were observed for frog performance. using 200 tilapias/ pond improved fish weight gain and dissolved oxygen concentration, as compared to 300 tilapias/ pond. this new rearing system provided an adequate environment for frogs, as there was weight gain and zero mortality during winter.

The Application of the Korean Dietary Pattern Score; KNHANES (Korean National Health and Nutrition Examination Survey) 2007  [PDF]
Kyung Won Lee, Ji Eun Oh, Mi Sook Cho
Food and Nutrition Sciences (FNS) , 2012, DOI: 10.4236/fns.2012.312221
Abstract: The aim of this study was to apply the Korean Dietary Pattern Score (KDPS) to Korean subjects based on traditional Korean-style meals. The KDPS is based on the 3-Chup Bansang (the traditional Korean daily table setting) and considers the intake of 6 major food groups according to the Korean Dietary Reference Intakes (KDRIs). The KDPS consists of 2 parts: the Korean-Style Meal Score (KSMS) and the Food Group Score (FGS). The KDPS was applied dietary data collected during the Korean National Health and Nutrition Examination Survey (KNHANES) in 2007. Socio-demographic status, gender, age, and body mass index are all factors that have been shown to be meaningful predictors for the KDPS. When the effect of the KDPS on risk of disease was evaluated, a higher total KDPS was associated with a decreased risk of elevated systolic blood pressure (p < 0.05) and hypercholesterolemia (p < 0.05). In addition, as the KSMS increased, the risk of central obesity (p < 0.05) and hypertension (p < 0.01) significantly decreased. A higher total KDPS suggests a greater diversity of food intake, and therefore greater dietary diversity appears to lower the risk of disease. The KDPS is relevant because it integrates scores for Korean-style meal patterns and meal evaluation from a nutritional perspective. In conclusion, the KDPS is appropriate for evaluating the quality of diet, adherence to Korean-style meal patterns, and risk of related diseases. These results will be useful for evaluating the nation’s dietary patterns, nutrition, and health status when planning nutrition policies and programs.

Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2018, DOI: 10.4236/jcdsa.2018.84021
Abstract: The aim of our study was to recognize different skin conditions of the face and neck using six biophysical parameters and to show the changes after the application of ultrasonic stimulation (US). We assessed the differences in the sebum, moisture, pores, wrinkles, pigmentation, and elasticity of the skin in the face and neck regions. A total of 30 healthy men in their 20s were enrolled. We used a skin diagnosis meter to assess the state of the skin. The sebum and pores of the face were more significant than in the neck. The amount of moisture in the U-zone was significantly higher than in other areas. Statistical differences were found between the pre-and post-measure-ment values in the sebum, moisture, wrinkles and pigmentation. Wrinkles and pigmentation were positively correlated. Our data showed that the changes in skin condition are associated with external stimulants. The effect of US on skin may differ depending on the part of the body, and some biophysical properties of skin vary depending on the location on the body.

Art and Design Review (ADR) , 2015, DOI: 10.4236/adr.2015.33009
Abstract: Whether the golden ratio is the favorite ratio for people is a controversial research issue until now. The purpose of this study is to investigate whether oriental people in Taiwan have the preference to the western culture originated golden ratio and to find out how the personality affects ratio preference by using the MBTI (Myers-Briggs Type Indicator) test to classify people into different personality types. First, 120 participants classified into 16 identified personality types by the MBTI test were screened out from 195 participants recruited in this study. After that, they were asked to estimate the preference to 15 horizontal and 15 vertical rectangles with varied ratios, respectively. The results of the study were summarized as follows: 1) The most popular personality types of the participants were ISTJ and ISFJ types, while ENTJ and ESTP types were much less popular; 2) The tendency of preference to varied ratios could be divided into three classes: people tended to like the ratio of a square, the preference to golden ratio was fair, and when the ratio increased to exceed the golden ratio would be gradually disliked; 3) The personality would affect the preference to golden ratio. The V6, H7 and H8 ratios were liked by people with different types of personality, I type and T type people preferred V6, people of S type and J type preferred H7 and people of F type and J type preferred H8; 4) Women with non-designer background liked golden ratio, but men disliked it. Most designers preferred golden ratio. This result could be used as guidelines for product design and market position setting.

American Journal of Analytical Chemistry (AJAC) , 2013, DOI: 10.4236/ajac.2013.49063
Abstract:

The concentrations of seven heavy metals (Pb, Cu, Zn, Cr, Fe, Cd and Mn) were determined in the organs of Rana esculenta (frog) obtained from River Guma, Benue State of Nigeria using Atomic Absorption Spectrophotometer. The analysis of the triplicate experiments showed that the intestine contained the lowest concentration (25.9%) of all the heavy metals detected, followed by the skin (30.5%), while the liver contained the highest concentration (43.6%). In all the frog organs, Fe had the highest concentration in the liver, followed by skin and lowest in the intestine. The trend of the heavy metals concentration in the organs can be represented as: Fe > Mn > Pb > Zn > Cu > Cr > Cd. The concentrations of all the metals in the liver, skin and intestine of the frog were found to be statistically significant. Generally, the levels of Pb, Fe, Cr and Mn in all the samples were analyzed above the tolerance limits by the WHO with exception of Cd, Cu and Zn that were below the permissible limits in the samples.

Splash Formation Due to a Frog Diving into Water  [PDF]
Yoshihiro Kubota, Osamu Mochizuki
World Journal of Mechanics (WJM) , 2015, DOI: 10.4236/wjm.2015.57014
Abstract: Herein, we present the results of our experimental investigation of splashes formed by a frog diving into water from the ground or from a leaf and the accompanying sound generated by the impact of the frog on the water. The experiments are performed by visualizing the flow with a high-speed camera. In addition, we used physical models comprising hydrophilic bodies made from hydrogel or acrylic resin to experimentally study how hydrophilicity affects the splash. In these experiments, we use the degree of swelling to define the hydrophilicity degree. The results show that different splashes are caused by the increase in water-film velocity upon an increase in hydrophilicity. For a body with strong hydrophilicity, at a relatively high film velocity, the water film forms when the body impacts the water surface separates from the body surface. In addition, an aircavity forms when the film separates from the body. We empirically examine the relation between the hydrophilicity degree and film velocity. The results indicate that increased hydrophilicity does not reduce the splash. Therefore, we conclude that reducing of the formation of water from the biomimetic point of view is related to the shape of body.

Open Journal of Preventive Medicine (OJPM) , 2013, DOI: 10.4236/ojpm.2013.33040
Abstract:

This study compared characteristics of Korean American men in two studies: a telephone survey with a random sample of Korean American men who reported daily smoking versus a smoking cessation clinical trial with a convenience sample of Korean American men who reported smoking at least 10 cigarettes a day. Guided by the Theory of Planned Behavior (TPB), both studies attempted to explain how much its theoretical variables (attitudes, perceived social norms, and self-efficacy) would explain quit intentions in Korean American men. Participants in the cessation study were less likely to have health insurance coverage (χ2 [2, 271] = 138.31, p = 0.001) than those in the survey study. The cessation group was more likely to smoke in indoor offices (χ2 [1, 231] = 18.09, p = 0.003) and had higher nicotine dependence than the survey group (t269 = 3.32, p = 0.001) but these differences became insignificant when only those who smoked 10 or more cigarettes were compared. Participants in the cessation study had more positive attitudes towards quitting (t267
