Cooked spaghetti soaked in 10%, 20%, and 40% aqueous glycerine solutions for ten minutes absorbed sufficient glycerine to plasticize that spaghetti during and after subsequent drying. The plasticizing action of the glycerine prevented fissuring(checking) and surface corrugation of the spaghetti at elevated drying temperature and large wet-bulb dry-bulb temperature difference. The drying temperature and the wet-bulb dry-bulb differences up to which such protection was provided as the glycerine soak concentration increased. Despite the reduction in drying rate, the drying time required to produce spaghetti with a water activity of 0.65 (the level normally required for stability) decreased as glycerine content increased. At high frying temperatures glycerine addition increased the extent of browning and shortened the period required to induce detectale browning, but in all instances browning started well after the product $a_w$ reached the 0.65 value required for the completion of drying. Because glycerine addition reduced drying times at any given set of drying conditions and permitted the use of higher drying temperatures, relatively low levels of glycerine addition (e.g. 0.15 kg glycerine/kg dry spagetti) can shorten spagnetti drying times by roughly 80% and perhaps by as much as 93%.

This study compared the texture characteristics and consumer acceptance of cooked wheat noodles produced in four countries, which were Korea, Japan, China, and Italy. Noodle types were selected after FGI (focus group interview). Eleven noodles were studied, and they were categorized into four types: udon, fried udon, oriental noodles of various thickness, and pasta. Color was measured as L (lightness), a (redness), and b (yellowness) values using a colorimeter. Lightness decreased when noodles were cooked, whereas redness and yellowness of cooked noodles were unchanged. Texture properties of wheat noodles in terms of hardness, springiness, cohesiveness, and chewiness were measured using the Rheometer. Italian spaghetti (spgt_IL), Korean fried udon (yk_udng_KR) had highest values for hardness. Korean udon had the highest value for springiness, whereas Chinese medium noodle (mid_CN) had the lowest value (p<0.05). Chinese thick noodle (thick_CN) and fettuccine (fettc_IL) showed lower hardness but higher springiness. Cohesiveness was significantly higher for Japanese udon (udng_JP), Chinese medium noodle (mid_CN), and Chinese thick noodle (thick_CN), whereas values for Korean thin noodle (thin_KR) and Korean fried noodle (yk_udng_KR) were significantly low (p<0.05). Spaghetti (spgt_IL) showed significantly high values for chewiness (p<0.05). For overall acceptability, thick Korean noodle showed the highest score with a level of 'slightly like'. Taste and texture attributes were highest among all noodles, and its high scores for chewiness and smoothness might contribute to its overall acceptance. Korean thick noodle, Korean udon, and Japanese udon were not significantly different from Korean or Japanese thin noodles. Japanese fried noodle (yk_udng_JP) showed the lowest acceptance among noodles in terms of color, flavor, taste, and texture. Chinese thick and medium noodles showed lower scores for overall acceptability, whereas chewiness was not significantly different from other noodles. Spaghetti and fettuccine showed lower scores in terms of overall acceptability, taste, texture, springiness, and chewiness.

The purpose of this study was to examine sodium intakes from soup, stew and noodle in school lunch using sodium content database separately developed for the solid part, liquid part of soup and stew (liquid based dishes) in middle school students. Two hundred fifty two middle school students in Seoul were asked about awareness towards reducing sodium intake and soup/stew intake provided in school lunch in September 2015. Only 68% of students were aware of the 'Day without soup/stew' event and why those events were held. Girls tend to consume more all solid and liquid parts of soups than boys in Miso soup (50.0% vs 36.2%), Bean sprout soup (56.6% vs 44.8%), Seaweed soup (61.8% vs 45.7%), Beef Radish soup (61.8% vs 59.5%), and Korean pasta soup with Kimchi (58.1% vs 46.6%). Average sodium intake from soup/stew/noodle dishes in school lunch was $379.6{\pm}183.9mg$ if behaviors of eating solid or liquid parts were considered and $556.8{\pm}190.6mg$ if behaviors of eating solid or liquid parts were not considered. Based on the results, the difference of sodium intake depends on the consuming behaviors of liquid parts of soup and stew dishes. It is necessary to establish and use a sodium database for each solid part and liquid part separately in soup, stew and noodle dishes to assess more accurate sodium intake. Education on the reduction of sodium intake through proper behaviors is salient in the achievement of a healthy diet.

Insects have long been consumed by humans as a supplemental protein source, and interest in entomophagy has rapidly increased in recent years as a potential sustainable resource in the face of environmental challenges and global food shortages. However, food neophobia inhibits the widespread consumption of edible insects, despite their high nutritional and functional value. The own characteristics of edible insect protein such as foaming properties, emulsifying properties, gelling properties and essential amino acid ratio can be improved by drying, defatting, and extraction. Although nutritional value of some protein-enriched bread, pasta, and meat products, especially essential amino acid components was increased, replacement of conventional food with edible insects as a novel food source has been hindered owing to the poor cross-linking properties of edible insect protein. This deterioration in physicochemical properties may further limit the applicability of edible insects as food. Therefore, strategies must be developed to improve the quality of edible insect enriched food with physical, chemical, and biological methods. It was presented that an overview of the recent advancements in these approaches and highlight the challenges and prospects for this field. Applying these strategies to develop insect food in a more familiar form can help to make insect-enriched foods more appealing to consumers, facilitating their widespread consumption as a sustainable and nutritious protein source.

In this paper, we propose a decision tree-based machine learning model that leads to food exchange table renewal by classifying food groups through machine learning for existing food and food data found by web crawling. The food exchange table is the standard for food exchange intake when composing a diet such as diet and diet, as well as patients who need nutritional management. The food exchange table, which is the standard for the composition of the diet, takes a lot of manpower and time in the process of revision through the National Health and Nutrition Survey, making it difficult to quickly reflect food changes according to new foods or trends. Since the proposed technique classifies newly added foods based on the existing food group, it is possible to organize a rapid food exchange table reflecting the trend of food. As a result of classifying food into the proposed model in the study, the accuracy of the food group in the food exchange table was 97.45%, so this food classification model is expected to be highly utilized for the composition of a diet that suits your taste in hospitals and nursing homes.

Purpose: To evaluate the clinical and radiologic results of the arthroscopic rotator cuff repair for partial articular surface tendon avulsion lesion. Materials and Methods: Twelve patients with symptomatic, partial articular surface tendon avulsion underwent arthroscopic rotator cuff repair between Mar. 2006 and Sep. 2008. The mean follow-up period was 18.3 months(12~36 months), and the mean age at the time of surgery was 46.9-year-old(19~64 years). Three cases had underwent rotator cuff repair after conversion to full-thickness tear and nine cases had transtendon repair with preserving bursal side cuff. Results: The mean VAS during motion was 6.2 before treatment and 2.0 at final follow-up (p<0.001). The passive forward flexion improved from $163.3^{\circ}$ preoperatively to $169.8^{\circ}$ postoperatively (p=0.038). The mean UCLA score improved from 18.4 preoperatively to 30.1 with 2 excellent, 8 good and 2 fair results at final follow-up. The mean KSS improved from 61.8 preoperatively to 76.8 at final follow-up. By examining the postoperative MR images of 5 patients, complete healing was observed in all of them. Conclusion: Arthroscopic rotator cuff repair may be an effective procedure for partial articular surface tendon avulsion in pain relief and improvement of the range of motion. If the remaining bursal side cuff fibers are intact, transtendon repair procedure with preserving the intact bursal layer of the tendon can be considered. If the remaining bursal side cuff fibers are friable or little, completion from partial-thickness to full-thickness tears with subsequent cuff repair can be considered.

Whole spine scanography (WSS) is a radiological examination that exposes the whole body of the individual being examined to x-ray radiation. WSS is often repeated during the treatment period, which results in a much greater radiation exposure than that in routine x-ray examinations. The aims of the current study were to evaluate the patient dose of WSS using computer simulation, image magnification and angulation of phantom image using different patient position. We evaluated the effective dose(ED) of 23 consecutive patients (M : F = 13:10) who underwent WSS, based on the automatic image pasting method for multiple exposure digital radiography. The Anterior-Posterior position(AP) and Posterior-Anterior position( PA) projection EDs were evaluated based on the PC based Monte Carlo simulation. We measured spine transverse process distance and angulation using DICOM measurement. For all patient, the average ED was 0.069 mSv for AP position and 0.0361 mSv for PA position. AP position calculated double exposure then PA position. For male patient, the average ED was 0.089 mSv(AP) and 0.050 mSv(PA). For female patient, the average ED was 0.0431 mSv(AP) and 0.026 mSv(PA). The transverse process of PA spine image measured 5% higher than AP but angulation of transverse process was no significant differences. In clinical practice, just by change the patient position was conformed to reduce the ED of patient. Therefor we need to redefine of protocol for digital radiography such as WSS. whole spine scanography, effective dose, patient exposure dose, exposure direction. protocol optimization.

Our Korean cuisine, due to growing interests in Korean culture along with outstanding performance of K-pop stars, is attracting worldly attention. As the worldly food pursuit tendency is changing from"fast food" to "slow food", preference for our Korean cuisine, which is well-known for its healthiness, is growing. However, our Korean cuisine, in terms of the world citizen's preference, as receiving evaluation for being lacking behind of Sushi of Japan, Dimsum of China, pizza and pasta of Italy, rice noodle of Vietnam, even to Indonesian and Middle-East foods, has not been achieving drastic advancements despite the cosmopolitan's attention. The previous studies were suggesting that, failure of a localization strategy that changes our traditional taste and aroma adaptive to foreigners' preference, is a cause for this. This study, through case studies of Korean food businesses in the US which have achieved a success through localization strategy, attempts to propose the following global entrepreneurial strategy of Koran food at the US dining out market. As a global entrepreneurial strategy for success, we propose, first a sales strategy not for Koreans but for local people as main customers, second a customization strategy which is not our traditional way but that meets local standard, and finally a committed entrepreneurship.
