Special nutritional foods are one category of processed foods. In this category, 5 different food standards are defined in the current rule of the Korean Food Code ; that is, infant formulae, complementary foods for infants and young children, foods nutrient supplementation, processed dietary fiber-based foods, and foods for special dietary uses. The major differences between the special dietary uses. The major difference between the special nutritional foods and the other processed foods is that the special nutritional foods are characterized by their dietary uses for specific population groups rather than food ingredients or manufacturing and processing techniques which characterize and distinguish most of other processed foods. Although several countries establish similar standards for this type of foods, they use different legal names such as foods for special dietary uses(U.S.A., CODEX, Japan), foodstuffs intended for particular nutritional uses(EC), or special purpose foods(Australia). In addition, there are some other differences in the definitions for these food types and categorization of food types among countries. The major difference in the definitions is the description of 'special dietary uses' by specifying certain population groups whose nutrient requirements are different from those of ordinary men due to physiological or physical conditions and therefore may not be sufficiently met by consuming ordinary foods. The categorization of this type of foods is based on the type of dietary uses in the other countries, whereas we include foods simply supplemented with nutrients or foods having certain components such as dietary fibers even if these foods types do not have special dietary sues. Recently, a revision of standards for special nutritional food has been proposed. However, the description of 'special dietary uses' is not clearly indicated in the definition, and some food types which should not be categorized into the special nutritional foods still remain in this category. In order to correct these problems, the standard of food labeling in the Food Safety Law needs to be revised along with revision of food standards in the Food Code.

This study was designed to compare the incidence and severity of premenstrual syndrome (PMS) between normal (N = 85) and overweight or obese (N = 28) college female students and investigated correlation between PMS, nutrient intake, hematological index and psychological index (depression, anxiety, stress). Each subject was asked a Menstrual Discomfort Questionnaire (MDQ) for PMS by 5 Likert scale. The PMS scores of women in the normal weight subjects ranked in order of severity were water retention (2.71), followed by behavioral change (2.58), negative affect (2.46), pain (2.31), autonomic reaction (2.27), decreased concentration (2.16). The symptoms of 'pain' and 'behavioral change' of overweight or obese subject were significantly higher than those of normal subject (p < 0.05). And total cholesterol concentration of overweight or obese subjects was significantly higher than in normal subject (p < 0.05). There was a significant positive correlation (p < 0.05) between the symptoms of 'negative effect' and BMI. And the triglyceride concentration was positively related with 'water retention (p < 0.01)'. The symptoms of 'decreased concentration' were negatively correlated with calcium (p < 0.01) and vitamin B6 intake (p < 0.05). The depression score were positively related with symptoms of 'behavioral change (p < 0.05)', 'negative affect' (p < 0.01), and the anxiety score was positively correlated with 'behavioral change (p < 0.05)' and 'decreased concentration (p < 0.05)'. The stress score was positively correlated with 'decreased concentration (p < 0.01)', 'behavioral change (p < 0.05)' and 'negative affect (p < 0.05)'. This suggests that PMS represents the clinical manifestation of a calcium, vitamin $B_6$ deficiency and psychological disorder. Therefore we concluded that nutrient supplementation, depression and stress management may help to relieve PMS symptoms.

This study was designed to identify how the incidence and severity of premenstrual. syndrome (PMS) correlate with the nutrient intakes and exercise habit of women. The subjects of this study were 299 women residing in Busan metropolitan city. Each subject was asked to complete a menstrual discomfort questionnaire (MDQ) for PMS and nutrient intakes. PMS symptom scores of women in their twenties ranked in order of severity were: behavioral change (2.45), followed by pain (2.36) and water retention (2.28), negative effects (2.20), autonomic reaction (1.91), arousal (1.87), decreased concentration (1.76) and decreased control (1.74). For Women in their thirties, the symptom of pain was the most dominant (2.93) followed by autonomic reaction (2.69) and behavioral change (2.54), and for those in their forties, negative effect (3.06) was highest, followed by pain (2.97) and autonomic reaction (2.86). The overall symptoms of PMS significantly increased with age (20': 2.07 points, 30': 2.34 points, 40': 2.47 points). There was no correlation of the BMI of the subjects with the symptoms of PMS, but there was a significant negative correlation between the symptoms of PMS and exercise frequency for women in their thirties and forties. Subjects in their twenties exhibited a significant negative correlation for PMS symptoms with the intake of carbohydrate (p < 0.05), calcium (p < 0.05) and vitamin E (p < 0.05). For subjects in their thirties, PMS symptoms were negatively correlated with the intake of calcium (p < 0.05) and vitamin C (p < 0.05); and in women in their forties, calcium (p < 0.01) and carbohydrate (p < 0.05) intakes were negatively correlated with PMS symptoms. This suggests that PMS represents the clinical manifestation of a nutrient deficiency state, especially calcium. Therefore, we concluded that nutrient supplementation and exercise management are likely to be of benefit in relieving PMS symptoms.

A 33-year-old woman visited the emergency department presenting with fever and dyspnea. She was pregnant with gestational age of 31 weeks and 6 days. She had dysuria for 7 days, and fever and dyspnea for 1 day. The vital signs were as follows: blood pressure 110/70 mmHg, heart rate 118 beats/minute, respiratory rate 28/minute, body temperature $38.7^{\circ}C$, and oxygen saturation by pulse oximetry 84% during inhalation of 5 liters of oxygen by nasal prongs. Crackles were heard over both lung fields. There were no signs of uterine contractions. Chest X-ray and chest computed tomography scan showed multiple consolidations and air bronchograms in both lungs. According to urinalysis, there was pyuria and microscopic hematuria. She was diagnosed with community-acquired pneumonia and urinary tract infection (UTI) that progressed to severe sepsis and acute respiratory failure. We found extended-spectrum beta-lactamase producing Escherichia coli in the blood culture and methicillin-resistant Staphylococcus aureus in the sputum culture. The patient was transferred to the intensive care unit with administration of antibiotics and supplementation of high-flow oxygen. On hospital day 2, hypoxemia was aggravated. She underwent endotracheal intubation and mechanical ventilation. After 3 hours, fetal distress was suspected. Under 100% fraction of inspired oxygen, her oxygen partial pressure was 87 mmHg in the arterial blood. She developed acute kidney injury and thrombocytopenia. We diagnosed her with multi-organ failure due to severe sepsis. After an emergent cesarean section, pneumonia, UTI, and other organ failures gradually recovered. The patient and baby were discharged soon thereafter.

The purpose of this study was to compare the elements of anti-discrimination laws on disability in major OECD countries. This study used the analysis framework for the elements of the anti-discrimination law on disability presented in the national report of Chopin et al.,(2018). In addition, It was analyzed including the Anti-Discrimination Act on Disability, the General Anti-Discrimination Act including Disability, the Equality Act in the UK, and the Human Rights Act in Canada. The research results were as follows. In Austria, Belgium, France and Sweden, it were found that the countrys satisfied all of the provisions of the Act on 'Direct discrimination', 'Indirect discrimination', 'Harassment', 'Legal standing to act on behalf of victims', 'Legal standing to act in support of victims' and 'Prohibition of victimisation'. In particular, in Korea, 'Legal standing to act on behalf of victims' and 'Legal standing to act in support of victims' were not included. However, it was a country that satisfied the provisions of the Act on 'Direct discrimination', 'Indirect discrimination', 'Harassment' and 'Prohibition of victimisation'. Finally, this study suggested legal and institutional supplementation.

Recently, quality control of the Liquefied Natural Gas Carrier (LNGC) cargo hold and block-erection interference areas using 3D scanners have been performed, focusing on large shipyards and the international association of classification societies. In this study, as a part of the research on LNGC cargo hold quality management advancement, a study on deep-learning-based scaffolding system 3D point cloud object detection and post-processing were conducted using a LNGC cargo hold 3D point cloud. The scaffolding system point cloud object detection is based on the PointNet deep learning architecture that detects objects using point clouds, achieving 70% prediction accuracy. In addition, the possibility of improving the accuracy of object detection through parameter adjustment is confirmed, and the standard of Intersection over Union (IoU), an index for determining whether the object is the same, is achieved. To avoid the manual post-processing work, the object detection architecture allows automatic task performance and can achieve stable prediction accuracy through supplementation and improvement of learning data. In the future, an improved study will be conducted on not only the flat surface of the LNGC cargo hold but also complex systems such as curved surfaces, and the results are expected to be applicable in process progress automation rate monitoring and ship quality control.

This study was carried out to investigate the effects of supplementation with a Bifidobacteria enhanced yogurt (BE0623 yogurt), which includes Bifidobacterium lactis BB12, Lactobacillus acidophilus, Streptococcus thermophilus, and Bifidobacterium lactis, in the management of irritable bowel syndrome (IBS) using animal models and clinical trials. In a rat study, a loperamide-treated group (LOP) showed reduced water content in fecal pellets but showed an increased number of fecal pellets in the distal colon. In addition, the BE0623 yogurt (L-BE0623Y) group had the fewest fecal pellets in the distal colon. Regarding the serum lipid parameters, the LOP group had a high-density lipoprotein (HDL)/total cholesterol ratio that was 43% lower than that of a normal water group (NOR), but the outcome for the L-BE0623Y group was 27% lower than the NOR group. In a human study, 116 adults with IBS were sampled as subjects and fed 300 mL of yogurt per day for an eight week period. There was an IBS improvement in the L-BE0623Y and commercial yogurt (L-CY) groups, though flatulence, stool consistency and frequency of defecation outcomes were also noted. Specifically, the L-BE0623Y treatment group showed significant effects with regard to defecation duration and urgency after the consumption of the yogurt used in this study. These results suggest that the Bifidobacteria-enhanced yogurt has superior effects with regard to relieving loperamide-induced constipation in rats and that regular consumption of L-BE0623Y is effective to improve IBS in humans.

This study investigated the effects of replacing fish meal (FM) with a mixture of four protein sources (wheat gluten, soy protein concentrate, tankage meal, and poultry byproduct meal) in an extruded pellet (EP) diet for olive flounder Paralichthys olivaceus. Five experimental diets were formulated with alternative proteins replacing 0%, 20%, 30%, 40%, and 50% of FM. Taurine and betaine were added as attractants in the diets. Triplicate groups of fish (initial body weight: $196{\pm}2g$) were fed the diets to apparent satiation. Over the course of a 6-month feeding trial, there were no significant differences between the groups in growth performance, feed utilization, survival, or villus height. The dry matter and protein digestibility of FM50 diet were significantly lower than those of the control diet at water temperatures below $18.5^{\circ}C$ in months 4 and 6. This is a highly significant first report on FM replacement in an EP diet given to olive flounder over a 6-month-long feeding period. It shows that the proper mixture of protein sources can replace up to 50% of FM in olive flounder EP diets with taurine and betaine supplementation. It also shows that 40% of FM could be safely replaced in EP diets during periods of low water temperature.

Key areas of digital contents, the games and animation industries are increasingly expanding. Therefore, training of a specialized workforce is required in accordance with these enterprises' growing demand. Education in the field of games and animation lies in cultivating talents with creative thinking, collaboration, and problem-solving skills. Thus, this paper aims to propose a PBSL teaching model for creative convergent talent through game and animation projects. The study will focus on the characteristics of creative convergence talents, project teaching, and related job competencies for game and animation education. Based on literature research, a 'Project Based Self Learning' instructional model is presented, in which creative thinking and collaboration competencies are explained in a way they can be performed by the learner. As a case study, D University's class was applied with PBSL. A survey showed that the autonomy aspects were higher than the creativity and convergence attitudes, indicating that the students improved their autonomy and motivation. However, the team composition needs further supplementation.

Today, energy bars are consumed not only as snacks but also as meal replacement foods. Convenience and nutritional supplementation are the main factors accounting for the increasing use of energy bars. Two hundred Chinese customers who attended the China Fisheries & Seafood Exposition in China, and had no inhibitions about consuming cereal bars were selected. The questionnaire was composed of CATA choices that selected both the reasons for liking and disliking four different types of cereal bars, namely topokki flavor (hot pepper paste), seaweed flavor, kimchi flavor, and ginseng flavor cereal bars with 10% of dried anchovy content produced by BadaOne Co. (Seoul, Korea). The purpose of the study was to investigate Chinese consumer's attitudes and acceptance of different flavored cereal bars containing protein and calciumrich anchovy. For the selected Chinese customers, the acceptance score for the seaweed flavor was the highest, followed by topokki, red ginseng, and kimchi. The acceptance for the topokki flavor was higher than for seaweed for the attributes of color except for general acceptance, flavor, aroma, and texture. The results of the survey showed that the acceptance of kimchi was the lowest, contrary to earlier predictions. The results of the Check All That Apply (CATA) analysis showed that the reasons for liking the seaweed & anchovy flavor were the most diverse, and there was no reason chosen for disliking this flavor. The reasons for liking this flavor were listed as sweet flavor, healthy, seafood flavor, malty flavor, texture, new/unique, and umami. In the case of topokki and kimchi, the reason for disliking the flavor was umami, and in the case of red ginseng, the ginseng flavor was the reason for both likes and dislikes. CA analysis showed that both the flavor and emotional factors were positive for seaweed & anchovy and topokki, but negative for red ginseng. As a result, seaweed & anchovy flavor, which is familiar to the Chinese people, should be the first cereal bar considered for a launch.
