This study was conducted to determine the effects of amino acid-enriched ruminally protected fatty acid (AARPFA) on plasma fatty acids and amino acids, growth performance and carcass characteristics of Korean native steers (Hanwoo) by simultaneous supply of fatty acids and limiting amino acids (methionine and lysine). Eighteen finishing Hanwoo steers, 18 months of age and weighing an average of $459.0{\pm}38.9\;kg$, were used for studies of the metabolism of plasma fatty acids and amino acids during supplementation of AARPFA. Also, 45 finishing Hanwoo steers, 16 months of age and weighing an average of $408.6{\pm}26.5\;kg$, were used for growth performance and carcass characteristics during supplemention of AARPFA. There were three treatments which comprised a basal diet supplemented with AARPFA at 0 g (T1), 50 g (T2) or 100 g (T3), respectively. Concentrations of saturated, unsaturated and total fatty acids in plasma were increased in T3 compared with other treatments (p<0.05). Concentrations of methionine and lysine in plasma were linearly increased with increasing levels of AARPFA (p<0.01). Average daily gain, dry matter intake and feed conversion ratio were not different among the treatments. Marbling score measured by ultra-sound scanning was higher in T3 than in T1 at 24 months of age (p<0.05). Rib eye area, back fat thickness, yield index and yield grade score were similar across the treatments. Marbling score and quality grade score were higher in T3 compared with other treatments (p<0.01). Thus, plasma fatty acids, methionine and lysine metabolism were affected by supplementing with 100 g of AARPFA which also had positive effects on marbling score and meat quality grade of finishing Hanwoo steers.

Pancreatic pseudocysts were complicated in 10-27% of acute pancreatitis and 11-41% of chronic pancreatitis. Asymptomatic pseudocysts require no treatment, but symptomatic pseudocysts should be decompressed. Surgical management had been the traditional approach to treating pancreatic pseudocysts. Endoscopic transpapillary or transduodenal cystoenterostomy were recently suggested as an alternative to surgery in order to avoid surgical complications. The success rates of endoscopic treatment was 65-94%, procedure related morbidity was 6-21% and mortality was 0-5%. We reported two cases of patients with pancreatic pseudocysts which were treated with endoscopic cystogastrostomy and proceeded to drain through stent and ENPD catheter.
Strategies for Oral Delivery of Macromolecule Drugs

Advances in biotechnology, gene manipulation, and protein engineering for macromolecule drugs, such as insulin, parathyroid hormone (PTH), calcitonin, human growth hormone, erythropoietin (EPO), and peptide YY (PYY) allow commercial production in large scale for diverse therapeutic uses. Other macromolecules, such as mucopolysaccharide heparin, have expanded markets through improvements in their pharmacokinetic and pharmacological effects. However, most products are available only as injectable forms and are limited to patients with no alternative therapeutic choices. Orally available macromolecule formulations are still unmet needs for improving patient compliance and expanding administration paradigms and indications. Oral delivery technologies including carrier systems, absorption enhancers, protease inhibitors, and modification by conjugating transporter or receptor recognition molecules have been developed and some are undergoing clinical studies. In this review, we discuss major obstacles for oral absorption of macromolecule drugs and summarize recent strategies to overcome the huddles related to enhancing intestinal permeation.

This study was conducted to determine the effects of dietary multi-nutritional targeted supplementation according to different growth stages on performance, blood metabolites and carcass characteristics of Korean native Hanwoo steers. Thirty two Hanwoo steers, 6 months of age and weighing $159.2{\pm}24.1\;kg$, were distributed into 2 groups: control group without any supplements, and multi-nutritional targeted supplementation (MNTS) treatment group supplied with wheat bran and catechins (WBC, 8 to 16 months of age), ruminally protected amino acid-enriched fatty acid (RPAFA, 17 to 28 months of age) and ruminally protected choline with vitamin E (RPCV, 22 to 28 months of age), respectively. Average daily gain was not significantly different between the two groups. During the late fattening period, concentrate, rice straw and dry matter intakes were relatively lower in MNTS than in the control group. Rib eye area, back fat thickness and yield index were similar between the two groups. Meat color was relatively lower in MNTS compared with the control group. The appearance rate of high quality grade ($1^{++}$, $1^+$ and 1) tended to be higher in MNTS compared with the control group. Thus, the present results indicate that dietary multi-nutritional targeted supplementation at different growth stages could be recommendable to increase income according to production of high quality Hanwoo beef without any negative effects on growth performance and carcass characteristics.

This paper examined consumer behaviors and attributes importances, and satisfaction of international fast food restaurants in Busan area, Korea. Through an questionnaire survey, 279 samples were completed. Results showed that convenience motive was dominant in the consumption of fast food restaurant and consumers mainly accompany their friends. The mean frequency of visit per month was 5.79 and the mean purchase amount per visiting was ₩5.512. This study found the most important attribute of fast food restaurant as food taste, followed by cleanness, kindness, quick service, and facilities. The most preferred brand was Mcdonald and KFC got highest score in repatronage intentions. The significant factors influencing the overall satisfaction of fast food restaurant were food taste, quick service and store facilities. The fast-food restaurant marketing implications of the study were discussed and further researches were suggested.

On the basis of the historical context of the Grid, this study defines the immanent attribute of the grid to view the role which coincidence's to the current historical sequence. Referring to the "Emerging Grind" of Toyo Ito. The "Emerging Grid" of Toyo Ito is to be understand as a dialectic result of the conflict against the grid of the modern era, and could imply a new order which in uniquely different from the present order. Because the existence of the limit of being applied to the majority, which was occured from a formal and structural complexity, it still has a limited opportunity to arouse the arrangement of the times
