Increase in greenhouse gas emissions during the last century has led to remarkable changes in our environment and climate system. Many policy measures have been developed to reduce greenhouse gas emissions across the world, many of which require our lifestyle changes from energy-intensive to energy-saving. One of the changes in our living patterns is to consider food miles. A food mile is the distance food travels from where it is produced to where it is consumed. Providing information of food miles will help people choose low mileage food, helping promote a "green consumption" action and lead to a low carbon society with emission reduction systems. In this study, 10 items are selected from 23 Harmonized commodity description and 2-digit coding system (HS) to estimate their food miles, and $CO_2$ emissions released in the transportation of imported food. For the estimation, four countries are chosen-Korea, Japan, United Kingdom (UK) and France, with Korea and Japan's 2001, 2003, and 2007 trade statistics and UK and France's 2003 and 2007 trade statistics used. As a result, Korea showed in 2007 the highest level of food miles and $CO_2$ emissions per capita among 4 countries. That suggests that Korea should make an effort to purchase local food to reduce food miles and use low-carbon vehicles for food transport, contributing to reducing greenhouse gas emissions.

Culture is being created and consumed as several form by human development. Populace is forming through movement of mass of people to specific place which influenced by urbanization and industrialization. Since cultural products are created on base of economic principles cultural content makers are make culture products after lot of study and analyze. In early days popular culture was accepted only by the meaning of the text which has settled already via country or company which was holding the capital. But today we can apply culture products freely by the power of public opinion and media art's growth. Especially fandom is giving the opportunity to consume the image of cultural products actively and offering the good influence to make it by several ways of activities to the culture producers. In this study, consumption as a cultural group formed by the fandom in public will be transformed into participatory groups by the influence of cultural activities with fan art reproduction. These changes in the consumption of culture products will make it in positive way. Thereby culture creator who thinks fandom as a group of culture capital maker only use it now for the indicator for predicting success of culture products. Will find out in this study how culture consumption is accomplishing by fan fiction and fan illustration in the fandom culture and how reproduced fan art is affects to culture creators.

1. Objective: This study was designed to analyze the characteristics of each Sasang constitutional type using the Temperament and Character Inventory (TCI). 2. Methods: A total of 135 healthy subjects (age 19-30) participated in this study, consisting of 35 Soyang-type, 66 Taeeum-type, 30 Soeum-type, and 4 Taeyang-type subjects. A Sasang Constitutional Medicine specialist determined each subject's Sasang constitutional type based on the Two Step Questionnaire for Sasang Constitution Diagnosis (TS-QSCD) and comprehensive constitutional assessment. The subjects were also asked to complete the TCI. 3. Results: Among the four temperament dimensions, the Soyang- and Taeeum-type subjects showed significantly higher scores than the Soeum-type subjects in Novelty Seeking (NS). The Soeum-type subjects showed significantly higher scores than the Taeum- and Soyang-type subjects in Harm Avoidance (HA) (Soeum type > Taeeum type > Soyang type). The Soyang-type subjects showed significantly higher scores than the Soeum-type subjects in Reward Dependence (RD). The Soyang- and Taeeum-type subjects showed significantly higher scores than the Soeum-type subjects in Persistence (P). Among the three character dimensions, the Soyang-type subjects showed significantly higher score than the Taeeumand Soeum-type subjects in Self-Directedness (SD) (Soyang type > Taeeum type > Soeum type). The Soyang-type showed significantly higher scores than the Taeeum-type in Cooperativeness (C). 4. Conclusions: Differences in temperament and character were discovered across the Sasang constitutional types. The Sasang constitutional characteristics should be investigated in larger studies in the future. Similar studies could add to the growing knowledge of Sasang constitutional typology and contribute to a more accurate Sasang constitutional diagnosis.

Poly (ethylene glycol)(PEG) - Poly (${\varepsilon}-caprolactone(CL)$) - Poly (D,L lactide(LA) (PCLA-PEG-PCLA) was synthesized by ring-opening polymerization to form temperature sensitive hydrogel triblock copolymer. The triblock copolymer was acrylated by acryloyl chloride. ${\beta}-amino$ ester was used as a pH sensitive moiety, in this study ${\beta}$- amino ester obtained from 1,4-butandiol diacrylate, and 4, 4' trimethylene dipiperidine, it have pKb around 6.6. pH/temperature sensitive penta-block copolymer (PAE-PCL-PEG-PCL-PAE) was synthesized by addition polymerization from acrylated triblock copolymer, 1,4-butandiol diacrylate, and 4, 4' trimethylene dipiperidine. Their physicochemical properties of triblock and penta-block copolymers were characterized by $^1H-NMR$ spectroscopy and gel permeation spectroscopy. Sol-gel phase transition behavior of PAE-PCL-PEG-PCL-PAE block copolymers were investigated by remains stable method. Aqueous media of the penta-block copolymer (at 20 wt%) changed from a sol phase at pH 6.4 and $10^{\circ}C$ to a gel phase at pH 7.4 and $37^{\circ}C$. The sol-gel transition properties of these block copolymers are influenced by the hydrophobic/hydrophilic balance of the copolymers, block length, hydrophobicity, stereo-regularity of the hydrophobic of the block copolymer, and the ionization of the pH function groups in the copolymer depended on the changing of environmental pH, respectively. The degradation and the stabilization at pH 7.4 and $37^{\circ}C$, and the stabilization at pH 6.4 and $10^{\circ}C,\;5^{\circ}C,\;0^{\circ}C$, of the gel were determined. The results of toxicity experiment show that the penta block copolymer can be used for injection drug delivery system. The sol?gel transition of this block copolymer also study by in vitro test ($200{\mu}l$ aqueous solution at 20wt% polymer was injected to mouse). Insulin loading and releasing by in vitro test was investigated, the results showed that insulin can loading easily into polymer matrix and release time is around 14-16days. The PAE-PCL-PEG-PCL-PAE can be used as biomaterial for drug, protein, gene loading and delivery.

Perineal hernia occurs spontaneously in older male dogs after idiopathic weakening of the pelvic diaphragm A 14-year-old uncastrated male shih tzu dog with right-sided perineal swelling was referred to the Veterinary Medical Teaching Hospital of Konkuk University. He had sign of perineal swelling for three years. Plain radiography documented the extent of rectal and colonic dilation in the herinal sac. During surgery, external anal sphincter muscle, coccygeus muscle and levator am muscle were weakened due to the three years of herniation. Internal obturator muscle transposition method was not enough for large defect, so mesh was applied to reduce the hernial sac. Internal obturator muscle transposition combined with using of polypropylene mesh was successfully performed in this dog.

Purpose: The purpose of this study is to understand what kinds of chemical substances have been used annually and to investigate incidents that occurred due to chemical hazard release and to analyze statistically clinically chemical injury patients who visited one regional emergency medical center in Gumi city with documented references review. Methods: Annual chemical waste emission quantity (Kg/Year) (Cwep) was reproduced using national web site data governed by the Ministry of Environment and 5 years (from 1 .Jan. 2010 to 31. Dec. 2014) of medical records of chemical injury patients who visited our emergency department were reviewed retrospectively. By applying exclusion criteria, 446 patients of 460 patients were selected. Results: Dichloromethane, Toluene, Trichloroethylene, and Xylene were always included within Top 5 of Cweq. Six cases of chemical incidents were reported and in 3 of 6 cases involving Hydrogen fluoride were included during the study period. Male gender and twenties were the most prevalent group. Injury evoking chemicals were Hydrogen fluoride, unknown, complex chemicals (over 2 substances) in sequence. The most frequent site of wounds and injuries was the respiratory tract. Gas among status, intoxication among diagnosis, and discharge among disposition was most numerous in each group. Conclusion: There have been no uniform clinical protocols for chemical wounds and injuries due to various kinds of chemicophysical properties and ignorance of antidotes. Therefore conduct of a multicenter cohort study and experiments for ruling out chemicals according to chemicophysical priority as well as development of antidotes and clinical protocols for chemical injury patients is needed.

We compared the long-term metabolic effects of equal amounts of carbohydrate from potato, rice and buckwheat on glycemic indices and blood lipids in healthy subjects. Nine healthy volunteers-2 men and 7 women were studied. All subjects ate diets based on the same-7-day rotating menu differing only in that the major source of carbohydrate (about 50% of daily total calories) came either from buckwheat, rice or potato. The study was conducted with a triple crossover design over three 7 day periods. On the morning of the 8th day, fasting blood was drawn from each subject to determine serum glucose, insulin, triglycerides, total and HDL-cholesterol. Subjects were then asked to eat breakfast with their respective carbohydrate within a 20 min period. Blood samples were drawn at 30, 60, 120 and 180 min after the start of breakfast to determine glucose and insulin levels. At 30 min the glucose response to the rice meal(7.15mmol/L) and potato meal(6.71mmol/L) were greater than the response to the buckwheat meal(5.855mmol/L) (P < 0.05). The mean area under the glucose response to the curve following the rice meal was greater than that following the buckwheat meal(P < 0.05). The insulin responses to the potato and rice meals at 30 and 60 min were greater than those to the buckwheat meal (P < 0.05). The mean area under the serum insulin response curve after the rice meal was greater than of buckwheat. Blood lipids, uric acid and glycosylated hemoglobin were not affected by the three meals. The study shows that the buckwheat meal has more beneficial effects on glycemic indices than either the rice meal or potato meal in healthy subjects.

Background: Several studies have reported the role of the miR-146a rs2910164 G > C polymorphism as a susceptibility factor for several digestive cancers. However, the results have been controversial. Therefore, we conducted the present meta-analysis to obtain the most reliable estimate of the association. Methods: PubMed, Embase and Web of Science databases were searched. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were extracted and pooled to assess the strength of the association between miR-146a rs2910164 G > C polymorphism and digestive cancer risk. A total of four eligible studies including 3,447 cases and 5,041 controls based on the search criteria were included. Results: We observed that miR-146a rs2910164 G > C polymorphism was not significantly correlated with digestive cancer risks when all studies were pooled into the meta-analysis. While we found that miR-146a rs2910164 polymorphism was not associated with gastric cancer, it was significantly linked with hepatocellular cancer risk (the homozygote codominant model: OR = 1.40, 95% CI = 1.04-1.87). In the stratified analysis by ethnicity, significant associations were observed in Chinese population for the allele contrast model (OR = 1.25; 95% CI = 1.12-1.38), for the homozygote codominant model (OR = 1.62; 95% CI = 1.28-2.04), and for the recessive model (OR = 1.38; 95% CI = 1.16-1.64). However, studies with Asian groups presented no significant association for all genetic models. Conclusions: This meta-analysis suggests that the miR-146a rs2910164 G > C polymorphism is a low-penetrant risk factor for digestive cancers in Chinese.

Purpose of this study was to investigate correlation between blood pressure(systolic and diastolic) and dietary Na, K intake pattern in the family members of normal and hypertension disease patients, besides patients themselves. Mean values of $systolic(126.6\pm18.0$ vs $119.3\pm17.2mmHg)$ and diastolic $(77.6\pm14.6$ vs $71.6\pm12.5mmHg)$ blood pressure in the family members of hypertension patients were significantly higher than those of normal subjects. Systolic blood pressure in normal subject group was positively correlated with age, body weight, sodium in soybean paste, and was negatively correlated with potassium in hotpepper paste, soybean paste and meats. Systolic blood pressure in the family member of hypertension patient was positively correlated with age, body weight, sodium in soybean Paste, and table salt intake, but urinary potassium excretion was negatively correlated. Diastolic blood pressure was positively correlated with age, body weight, and table salt intake, and was negatively correlated with potassium in hotpepper paste and soybean paste in normal subjects groups. In the family members of hypertension patients group, diastolic blood pressure was positively correlated with age, body weight, and table salt intake, and was negatively correlated with sodium in hotpepper Paste and soybean paste and urinary potassium excretion. In total, tendency of negative correlation between Na intake pattern and systolic blood pressure in normal subjects was much obvious than that in the family members of hypertension patients. Urinary potassium excretion in the family members of hypertension patients was also negatively correlated with both systolic and diastolic blood pressure.
