The purpose of this study was to investigate whether a web-based nutrition counseling could lead to beneficial outcomes in food intake and serum lipids of patients with hyperlipidemia. Forty hyperlipidemic patients, twenty of them were hypercholesterolemia and the other twenty were hypertriglyceridemia, participated in a web-based nutrition counseling program. At the first nutrition counseling, the patients were counselled through interview and then follow up nutrition counseling was accomplished four times during eight weeks through a web-based internet program. Various markers of disease risk including anthropometric indices, food intakes and serum lipid levels were measured before and after the web-based nutrition counseling. After nutrition counseling, body mass index significantly decreased in both groups and waist to hip ratio significantly decreased in male hypercholesterolemic patients (p<0.05). Total-cholesterol decreased from 262.2 mg/dL to 234.9 mg/dL, LDL-cholesterol decreased from 186.8 mg/dL to 160.5 mg/dL in hypercholesterolemic patients, triglyceride decreased from 288.6 mg/dL to 211.9 mg/dL and total-cholesterol decreased from 217.2 mg/dL to 198.7 mg/dL in hypertriglyceridemic patients after nutrition counseling. Anthropometric value and nutrient intakes were improved after nutrition counseling. Energy, fat and saturated fatty acid intakes decreased significantly in both groups (p<0.05). Therefore, this study shows that the web-based nutrition counseling is effective in improving food habit and influences positively in serum lipid levels of the patients. In addition, these results indicate that internet presents us with potential as a new medium for nutrition counseling in informationized society.

Control independence has been put forward as a new significant source of instruction-level parallelism for superscalar processors. In branch prediction mechanisms, all instructions after a mispredicted branch have to be squashed and then instructions of a correct path have to be re-fetched and re-executed. This paper presents a new branch misprediction recovery mechanism to reduce the number of instructions squashed on a misprediction. Detection of control independent instructions is accomplished with the help of the static method using a profiling and the dynamic method using a control flow of program sequences. We show that the suggested branch misprediction recovery mechanism improves the performance by 2~7% on a 4-issue processor, by 4~15% on an 8-issue processor and by 8~28% on a 16-issue processor.

The current study was carried out to investigate the effect of oral administration for 30 days of the Jijang kimchi extracts on prevention of diabetes, alcoholic liver injury and reduction of blood lipids in laboratory rats with alcoholic liver injury and diabetes induced by streptozotocin. In a diabetic model animals, the blood lipid profile, ALT, and AST levels were lower in kimchi extract groups compared to DC (diabetes control) group, and blood glucose level of DCJK (DC+oral administration with Jijang kimchi extracts) group was lower than that of DCCK (DC+oral administration with commercial kimchi extracts) group. Insulin levels were increased in order of NC (normal control), DCJK > DCCK > DC groups. In alcoholic liver injury model animals, ALT, AST and bilirubin were lowed in order of AC (alcohol group received 1 bottle of soju) > ACCK (1 bottle of soju plus oral administration with commercial kimchi extracts) ACJK (AC plus oral administration with Jijang kimchi extracts) > NC groups. In the clinical pathologic findings of liver tissue, AC group was severely injured, and tended to be improved in groups eating a 1 bottle of soju plus oral administration with kimchi extracts, especially Jijang kimchi extract group. The results suggest that eating Jijang kimchi can improve insulin secretion ability while lowering blood lipid profile, blood sugar and ALT, AST, and bilirubin levles in diabetic and alcoholic liver injury model animals.

The purposes of this study were to: (a) identify students' patronage behaviors on university foodservice, (b) evaluate customers' perception and detect complaints on food service quality, and (c) recommend new design of food service operation by identifying relative importance of university foodservice attributes. The questionnaire was developed and distributed to 400 undergraduates. Statistical data analysis was completed using SPSS/Win 12.0 for descriptive analysis and conjoint analysis. The results of this study were summarized as follows: Students were patronizing university foodservice 3.4 times per week because of 'a short distance', 'a low price' and 'speedy meals' and evaluated overall satisfaction and value as low level. Customers were dissatisfied with eight among twelve food service attributes including handling customer's complain ASAP, According to conjoint analysis, price $(37\%)$ was considered as the most important factor and atmosphere $(30\%),\;food\;(22\%)$ and distance $(11\%)$ were the next factors. Profile 2, which had 4 attributes of a location within 6-10 min, comfortable circumstances, a meal served with 4 side-dish and dessert and a meal price of \2,000 firstly, were recommend as new food service operation model.

The recent announcement of the EPUB3.0 e-book standard with enhanced features is expected to bring about much development and change to the production and circulation of e-books. This study thus set out to implement an EPUB3.0-based e-book containing various layout screens and interactive functions to stimulate readers' interest and investigate the production method considering the simultaneous publication of paper book and e-book. As for methodology and content, the investigator completed an edition and layout design and added an interactive function to it with Adobe Indesign CC(2014) and saved it as an EPUB3.0 file. She then opened the save EPUB file in the Sigil program, checked its specific codes and errors, and made revisions for its completion. The completed EPUB3.0 file was put to the test by installing four EPUB viewers, which were capable of implementing the EPUB3.0 features well based on the fitness results of epubtest.org and uploading files, in desktop and mobile devices. The present study claims its significance by implementing an EPUB3.0-based e-book capable of fixed layout and interactive features, cutting down the time and costs to make an e-book considerably by linking and using a production program, and proposing the possibility of simultaneous publication of paper book and e-book.

Nowdays, Most of Internet Contents delivered as a compressed file. It gives many advantages like deduction of communication bandwidth and transmission time etc. In case of JPEG Compression, Quantization is the most important procedure which accomplish the compression. In general signal processing, Quantization is the process which converts continuous analog signal to discrete digital signal. As you known already, Quantization over JPEG compression is to reduce magnitude of pixel value in spatial domain or coefficient in frequency domain. A lot of Data Hiding algorithms also developed to applicable for those compressed files. In this paper, we are going to unveil the influence of quantization table which used in the process of JPEG compression. Even thought most of algorithm modify frequency coefficients with considering image quality, they are ignoring the influence of quantization factor corresponding with the modified frequency coefficient. If existing algorithm adapt this result, they can easily evaluate their performances.

A noticeable amount of Kirkendall voids formed at the Sn-3.5Ag solder joint with electroplated Cu, and that became even more significant when an additive was added to Cu electroplating bath. With SPS, a large amount of voids formed at the $Cu/Cu_3Sn$ interface of the solder joint during thermal aging at $150^{\circ}C$. The in-situ AES analysis of fractured joints revealed S segregation on the void surface. Only Cu, Sn, and S peaks were detected at the fractured $Cu/Cu_3Sn$ interfaces, and the S peak decreased rapidly with AES depth profiling. The segregation of S at the $Cu/Cu_3Sn$ interface lowered interface energy and thereby reduced the free energy barrier for the Kirkendall void nucleation. The drop impact test revealed that the electrodeposited Cu film with SPS degraded drastically with aging time. Fracture occurred at the $Cu/Cu_3Sn$ interface where a lot of voids existed. Therefore, voids occupied at the $Cu/Cu_3Sn$ interface are shown to seriously degrade drop reliability of solder joints.

Gamrosu is a modified fasting therapy beverage (431 kcal/d). A retrospective observational study was conducted to investigate the detoxification feasibility of Gamrosu. Three cases were reviewed which participants have finished the fasting with Garmrosu for 10 consecutive days. Detoxification profiles of Gamrosu were reviewed at pre- and post-fasting sessions. Post-Gamrosu session, -6.3% of average weight, -6.5% of average body fat mass and -6.6% of average muscle mass were reduced with the nutrition indices being improved. The inflammation indices showed the significant diminished profiles. Liver/kidney functions and the standard of electrolytes were maintained within normal range in stable manners, however, marginal elevation of total bilirubin and mild ketoacidosis were observed. The indices of oxidative stress decreased and those of antioxidative activity increased. The fatigue scale scores indicated lower scores except insomnia symptom. Taken together, detoxification profiles of Gamrosu were sufficiently feasible and the observed findings should be considered for further clinical studies.

This paper proposes an adaptive resource self-management system that collects system resources, user information, and usage patterns as context information for utilization in self-configuration. This system ill ease the system maintenance burden on users by automation of large part of configuration tasks such as install, reconfiguration and update, and will also decrease cost and errors. Working from the gathered context information, this system allows users to select appropriate components and install them for user's system context. This also offers a more personalized configuration setting by using user's existing application setting and usage pattern. To avoid the overload on central server to transfer and manage related files, we employ Peer-to-Peer method. h prototype was developed to evaluate the system and a comparison study with the conventional methods of manual configuration and MS-IBM systems was conducted to validate the proposed system in terms of functional capacity, install time and etc.
