The purpose of this study was to assess and evaluate salty taste preferences. Samples for the salty taste test were made by adding sodium chloride to soybean sprout soup at five different concentrations: 0.08% (unsalty) ; 0.16% (slightly unsalty) ; 0.31% (neither unsalty nor salty) ; 0.63% (slightly salty) ; and 1.25% (salty). Over 4,210 subjects were randomly selected and tested over a three-year period from 2005 to 2007 in Daegu. The results of the taste test were as follows: Forty-five percent of the subjects preferred soup with a salty taste and slightly salty taste. Most subjects preferred soup with a 0.31% concentration of sodium chloride. There were positive relationships between intensity and preference in 0.08%, 0.16%, and 0.31% concentrations, but there were negative relationships between intensity and preference in 0.63% and 1.25% concentrations (p<0.01). Upon examining a relationship between the taste assessment results and salty eating attitude scores, it was found that the subjects who preferred slightly salty and salty taste showed higher total scores in terms of habitual preference for/enjoyment of eating salty foods than the other groups. Comparing the taste test results with the subjects' stated preference, it was found that 70.3% of the subjects who were classified as preferring salty taste recognized this preference and 53.3% of the subjects who were classified into the population than tends to eat slightly salty food responded that they also tend to prefer a salty taste. Based on these results, this salty taste assessment study can be used as a practical and useful nutrition education tool for assessing and possibly reducing salt intake.

This study was conducted to develop and evaluate food safety training program for employees in foodservice operations. The developed CD-ROM was consisted of 5 parts: foodbome illness, personal hygiene, food handling in food production steps, HACCP system, and sanitary facilities. It has made slides for all contents, the animation and movie to raise interests and concentrations, and illustrations and pictures to understand. The evaluation checklists were developed 15 questionnaires including understanding(5), information(3), concentration(4), recommendation(2), and the most important factor(1) and measured by Likert 5-point scale. Fifty-four dietitians in Daegu and Gyeongbuk schools, hospitals, and industries foodservice operations responded to the surveys. The results are as follows; The most important part in the CD-ROM was personal hygiene(33.3%). The total mean was $3.95{\pm}0.41,\;3.91{\pm}0.46$ on understanding, $3.89{\pm}0.50$ on information, $3.87{\pm}0.55$ on concentration and $4.29{\pm}0.49$ on recommendation. The score was significantly higher in the recommendation part than others. Overall, as the developed CD-ROM has achieved fine score, a study on the effect of education needs to be followed. Moreover, consistent and organized education by developing a variety of sanitation education methods should be conducted.

Bronchial artery embolization (BAE) is a well accepted and effective treatment for massive and recurrent hemoptysis. However, several complications of BAE have been reported. Cortical blindness is defined as a loss of vision caused by bilateral occipital lobe lesions with normal pupillary light reflexes and a normal fundus. The reported incidence of transient cortical blindness(TCB) after cerebrovertebral angiography is approximately 1%. Two cases of TCB after BAE were found from a Medline search. Here, we report another case of TCB who was treated with BAE for a massive hemoptysis.

The purpose of this study was to evaluate changes in the microbiological safety of food ingredients supplied to elementary school food services during processing. For this purpose, fifteen food ingredients and twelve factories were chosen in the provinces of Daegu and Gyeongbuk. Total plate counts and coliform counts were reduced in the ingredients after washing, but they increased after packing. After packing, the following levels of total plate counts and coliforms were detected, respectively: peeled bellflower roots ($1.2{\sim}3.6{\times}10^6$, $3.1{\sim}4.6{\times}10^5$ CFU/g), blanched vegetables ($5.6{\times}10^3{\sim}2.0{\times}10^5$, <5~$1.5{\times}10^4$ CFU/g), soybean curd (<5~$5.4{\times}10^3$, <5~$2.2{\times}10^3$ CFU/g), buckwheat starch jelly (<5, <5 CFU/g), soybean sprouts ($1.2{\times}10^6{\sim}1.8{\times}10^7$, $2.4{\times}10^5{\sim}4.3{\times}10^6$ CFU/g), mackerel ($2.2{\times}10^2$, $1.3{\times}10^2$ CFU/g), chicken ($3.8{\times}10^4$, $6.7{\times}10^2$ CFU/g), pork ($6.7{\times}10^2$, <5 CFU/g), and beef ($9.4{\times}10^2{\sim}5.2{\times}10^4$, <5~$2.1{\times}10^3$ CFU/g). Generally, the microbiological safety of the food ingredients was better during the processing stage than during the other stages, with the exception of packing. Staphylococcus aureus, E. coli, and Bacillus cereus were detected in small amounts on the peeled bellflower roots, chicken, and pork, respectively. These results indicate that peeled bellflower roots, chicken, and pork need to be sanitized at the washing stage and cross contamination must be prevented at the packing stage.

The present study was conducted to investigate the effect of nutrition education program on nutrition knowledge, eating behaviors, food habit, nutrient intakes in obese children and their parents who live in Gumi city. The subjects were 16 obese boys, 20 obese girls with obesity index over 130% and 36 of their parents. The nutrition education for the subjects was carried out by the professional personnel such as doctors, professors, and dietitians. The children were provided with well-balanced lunch meals and had 40 min-lectures on the reasonable weight management, 40 min-games and also had regular exercises (stretching, swimming) for 90 mins everyday during 2 weeks of the program. The parents had 90 min-lectures on childhood obesity, diet therapy, behavior modification, and exercise for 6 times. The nutrition knowledge, eating behaviors and food habits were surveyed by using questionnaires before and after the education. The nutrition intakes of the children were surveyed before and after the education by 3-day food record method. The nutrition intakes of the parents were surveyed before and after the education by using semi-quantity questionnaires. After the education, the mean nutrition knowledge scores were significantly improved compared with the pretest scores in both children and parents. After the education, all subjects' eating behaviors were significantly changed positively and calorie and carbohydrates intakes were significantly decreased and vit. C was significantly increased in obese children. The food habits of the parents were significantly improved after the education. These findings show that the well-designed nutrition education program for obese children and their parents can be an effective approach to help them to improve their nutrition knowledge and to establish desirable food habits and eating behaviors.

In this paper, we propose a novel neural relighting that infers a relighted rendering image based on the user-guided specular highlight map. The proposed network utilizes a pre-trained neural renderer as a backbone network learned from the rendered image of a 3D scene with various lighting conditions. We jointly optimize a 3D light position and its associated relighted image by back-propagation, so that the difference between the base image and the relighted image is similar to the user-guided specular highlight map. The proposed method has the advantage of being able to explicitly infer the 3D lighting position, while providing the artists' preferred 2D screen-space interface. The performance of the proposed network was measured under the conditions that can establish ground truths, and the average error rate of light position estimations is 0.11, with the normalized 3D scene size.

This paper proposes a portable 3-D scanning technique using a laser pointer. 3-D scanning is a process that acquires surface information from an 3-D object. There have been many studies on 3-D scanning. The methods of 3-D scanning are summarized into some methods based on multiple cameras, line lasers, and light pattern recognition. However, those methods has major disadvantages of their high cost and big size for portable appliances such as smartphones and digital cameras. In this paper, a 3-D scanning system using a low-cost and small-sized laser pointer are introduced to solve the problems. To do so, we propose a 3-D localization technique for a laser point. The proposed method consists of two main parts; one is a fast recognition of input images to obtain 2-D information of a point laser and the other is calibration based on the least-squares technique to calculate the 3-D information overall. To verified our method, we carry out experiments. It is proved that the proposed method provides 3-D surface information although the system is constructed by extremely low-cost parts such a chip laser pointer, compared to existing methods. Also, the method can be implemented in small-size; thus, it is enough to use in mobile devices such as smartphones.

The purpose of this study was getting information to set up the new roles focused on nutrition education for school dietitians as nutrition teachers. One hundred thirty nine school dietitians and 1169 elementary school children residing in Daegu city and Gyeongbuk province were surveyed for this study. Sixty eight percent of the school dietitians perceived 1st-3rd year of the elementary school is the most proper time to start nutrition education, and 59.0% of them wanted to practice nutrition education as a discretion teaching time. The largest proportion(79.1%) of the school dietitians expected that nutrition education is helpful to get good dietary habit. School dietitians responded that major contents that should be included in the nutrition education was balanced diet, diet and habit, managing healthy weight, dining etiquette, food safety and problems of environmental contamination. Fairly large proportion of the students(64.4%) responded nutrition education is urgently needed. The contents of the nutrition education students wanted most were cooking and healthy diet. Forty six percent of the students perceived school dietitians are responsible for nutrition education and they wanted to have nutrition education as a part of special activity class. The most preferred frequency of nutrition education was 1 hour/week and 46.2% of the students responded they wanted to participate cooking camp.

The purpose of the study was to examine the adolescents' awareness and practice of Dietary Action Guide for Adolescence, which was developed by the Ministry of Health & Welfare. Subjects were middle and high school students, selected one class each from all of the 16 provinces in Korea, which were 32 schools and 998 students all together. The subjects were asked to self-evaluate the degree of awareness and practice of Dietary Action Guide using the 5 point-Likert scale from July to September, 2010. On average, 55.1% of the students responded that they were aware of the Dietary Action Guide and 49.4% answered that they put Guidelines into practice. The average score of awareness and practice were $3.54{\pm}0.24$ and $3.42{\pm}0.33$, respectively. The awareness score was higher than those of practice score in all the questions in the 6 categories. Awareness score of female students was higher than those of male students but there was no difference by residence area. Awareness and practice of the nutrition education-experienced were higher than those of the inexperienced. Practice score was higher among middle school-students compared to high school students, which reflected the opportunity of taking nutrition related classes. This finding shows that nutrition education for adolescents is important to change their dietary behaviors regardless of gender, residence area and school level.

We evaluated the sanitation management practices in food delivery companies that supply food and food ingredients to school food-service establishments. We examined the practices 38 food delivery companies located in the Daegu and Gyeongbuk areas of Korea. Sanitation management practices were self-evaluated using a Likert 5-point scale. The total mean score for delivery company sanitation performance was 4.45. Scores for perceived sanitation management performance of the delivery companies were: food ingredient storage and management (4.47); delivery worker (4.47); and management of delivery van (4.38). The personal hygiene score was significantly higher than those of other sanitation inspection items evaluated (p<0.05). Delivery company managers believed that their sanitation management programs kept food hygienically and that the food was delivered to a high level of safety and at optimal quality. However, the managers thought that food quality standardization was needed to ensure transparency in delivery. Food delivery companies wish to obtain sanitation and supply certifications if they meet certain criteria.
