The focus of the study was to maximize the output data for Korean cuisine. This study evaluated the nutritional retention factor for different cuts of Korean beef (Hanwoo beef) subjected to various cooking methods. Five cuts (short rib, sirloin, chuck roll, tenderloin, and fore shank) of Korean Hanwoo beef were prepared and used in this experiment. Two different cooking methods (dry-heat cooking and moisture-heat cooking) were applied to each cut. The sodium contents of dry-heat cooked short rib (86.44), sirloin (76.81), tenderloin (86.65), and fore shank (85.89) decreased. Potassium contents of dryheat cooked sirloin (94.99), chuck roll (89.19), and fore shank (92.66) decreased. Calcium contents of dry-heat cooked sirloin (61.49), chuck roll (73.97), and fore shank (91.46) decreased. Iron contents of dry-heat cooked chuck roll (79.71), and tenderloin (90.79) decreased. Phosphorus contents of dry-heat cooked sirloin (87.87), and tenderloin (99.88) decreased. Mineral contents of all cuts cooked by moisture-heat decreased. Finally, the nutritional retention factor represents output data of each cooking method with yield % of each item.

Air voids in hardened concrete have an important influence on concrete durability such as resistance of freezing and thawing, permeability and surface scaling resistance. Linear traverse method and point count method in ASTM standard method have been widely used to estimate the air void system in hardened concrete. However, these methods are not used at present time, because they are is exhausted much time and effort. In previous study, air voids system of concrete was estimated by spacing factor. The purpose of this study organizes image analysis method by analyzing air contents, air voids distributions by diameters, air voids system as well as spacing factors after hardened concrete. The experimental variables institute of depth of specimen(top, middle, bottom), air contents(AE contents 0, 0.01, 0.03%).

The study explored the key factors(content satisfaction factor, functional satisfaction factor, inertia factor and situational factor) that influence OTT users' continued use from the perspective of Behavioral Economics. In addition to rational factors that make OTT users feel satisfied after experiencing the contents and functions by the platform, we assumed that it would also affect habitual factors from the 'status quo bias'. To verify this, an online survey was conducted on 523 adults in 20s and 40s who have subscribed to the Top3 OTT platform(Netflix, Wavve, and Tving). As a result of regression analysis, 'content satisfaction factor', 'functional satisfaction factor' and 'inertia factor' were significant in OTT continued use. 'Inertia factor' did not affect domestic OTT users. Unlike previous studies that supposed OTT service users as beings with complete rationality, this study is meaningful to explain OTT continued use by applying 'bounded rationality'.

Among 179 specimen diagnosed with ASCUS but did not go through biopsy or other tests, 26 cases (14.52%) showed positivity in HPV Hybrid Capture II Test. There were 25 cases of HPV high risk factor(+), marking 13.96%, and 3 cases of low risk factor(+) at 1.67%. According to cytology manifestation, patients with over LSIL can increase their complete recovery rate with continuous tests, but most patients diagnosed ASCUS do not go through any tests at all. It is considered that in order to prevent and start early treatment on cervical cancer, the HPV Hybrid Capture II Test must be enforced to patients diagnosed with ASCUS. Negative patients should go through routine screening, and positive patients should receive treatment after colposcopy.
