The purpose of this study was to investigate several aspects of eating out behaviors especially in relation to Chinese food. Self-administrated questionnairs were completed by 556 food-related major college students in Kangwon-do area. The results were as follows: 1. The frequencies of eating out were not significantly different by gender, type of residence, and the amount of spending money per month of the subjects. 2. Korean foods had a tendency to be selected as a first choice of eating out with both family and friends. The subjects preferred Korean foods, Western foods, Chinese foods and Japanese foods in order with their family but flour based foods, western foods and chinese foods in order with their friends. Japanese foods were not selected at all when they ate out with friends. 3. The 80.7% of male subjects and the 58% of female subjects liked Chinese foods. High calorie food was the feeling about Chinese foods for the male subjects and greasy food was for the female subjects. Taste was the most considered factor for choosing Chinese foods. 4. The 80% of subjects answered that Chinese food culture affected that of Korea. The 77% of subjects thought Chinese noodles were settled down to Korea. 5. Using MSG to Chinese foods was recognized as health-concerning factor for 67% of male subjects and 72% of female subjects.

This study examines knowledge, attitudes and behaviors toward sexual activity among 412 college students in Seoul. An 127-item questionnaire is used in order to understand and consider alcircumstances involved in decisions about sexual activity, and to reflect to the course on healthy sexuality. The major findings are as follows: 1. ‘Books/media’ and ‘friends’ are the primary source of sexual knowledge. 2. Despite the increased number of sxeducation programs, peers apparently remain the major source of information and the counsellor of the sexual problems(71.6%). 3. About ninety percent of males and 14.2 percent of females masurbate. Although mastubation is anormal response to pleasurable bodily feelings, students feel ‘unnatural’, ‘bad’ or ‘guilty’. 4. For some students, sexual intercourse is perceived as the natural outgrowth of love. More than thirty oercent of males and 8. 1 percent of females are engaged in inter -course. 5. Asking parents or teachers to be specific in talking about sex makes it uncomfortable to discuss sex. 6. Sex education should begin in the family and in school in early childhood and continue throughout life. 7. Sexual feelings and emotions are stirred up differently between male and female by sexual sensations. 8. Half of the intimate relationship with opposite sex shows a love relationship with sexual closeness and pleasure. Unguided reading or peers remain the primary source of information about topics like masurbation and sexual technique. Thus, schools should be responsible for the more value-laden subjects (such as birth control, homosexuality, and sexual techniques). And inclusionof a peer education componebt that modified college students' perceived peer norms may be the intervention method of choice. The prevention of health problems is far more desirable than treatment. The earlier the knowledge and skill to make healthful decisions are instilled, the greater the chance a healthful lifestyle will be adopted. School is the logical place in our society to provide the college students learning opportunities essential to developing the knowledge and skills to choose a healthful life course.

In the past, commercial advertisements were produced mainly by advertisements that introduced functions, descriptions, or brands that the product had. However, the current advertising market appeals to the product by projecting emotion into the product in line with the consumer's expanded role of storytelling. Nudge effects can help you make the right choice in an economic and behavioral sense. Storytelling, which includes these nudge effects, allows people to communicate with people, thereby allowing consumers and businesses to move in the direction they want. This study understands the concept of nudge effect through commercial advertisement of Seoul Milk and studies the impact of corporate commercial advertisement on the analysis of the interactions between nudge effect and storytelling on the company's perception change as a consumer. The purpose of this study is to study the influence of the nudge effect. The results of this study have affected the perception of the entity, affected by the ripple effect of the nudge effects.

Among all serious diseases globally, diabetes (type 1 and type 2) still poses a major challenge to the world population. Several target proteins have been identified, and the etiology causing diabetes has been reasonably well studied. But, there is still a gap in deciding on the choice of a drug, especially when the target is mutated. Mutations in the KCNJ11 gene, encoding the kir6.2 channel, are reported to be associated with congenital hyperinsulinism, having a major impact in causing type 1 diabetes, and due to the lack of its 3D structure, an attempt has been made to predict the structure of kir6.2, applying fold recognition methods. The current work is intended to investigate the affinity of four phytochemicals namely, curcumin (Curcuma longa), genistein (Genista tinctoria), piperine (Piper nigrum), and pterostilbene (Vitis vinifera) in a normal as well as in a mutant kir6.2 model by adopting a molecular docking methodology. The phytochemicals were docked in both wild and mutated kir6.2 models in two rounds: blind docking followed by ATP-binding pocket-specific docking. From the binding pockets, the common interacting amino acid residues participating strongly within the binding pocket were identified and compared. From the study, we conclude that these phytochemicals have strong affinity in both the normal and mutant kir6.2 model. This work would be helpful for further study of the phytochemicals above for the treatment of type 1 diabetes by targeting the kir6.2 channel.

American charter schools are independent public schools of choice, freed from rules but accountable for results. Charter schools have celebrated the 25th anniversary of its creation in 2017 and become part of landscape of public education in America. However, little research has been conducted on an individual charter school. This study aimed to examine the major factors of a successful charter school. A qualitative approach was employed. Seven one-hour in-depth interviews were conducted with semi-structured interview questions. And four teachers were participated. The conclusions are as follows: First, there is the combination of system and cultural factors as major successful factors of the Dayton Early College Academy. Second, system factors are the gateways and the advisory that is a twin at the charter school. The findings are considered to be applied for Korean educational settings and the implications can be used for policy development in Korea.

The results are summarized as follows. First, it is necessary to improve class time of SW education for the college students and revise the SW curriculum to improve SW education capacity for teacher students. Second, in the liberal arts course, it is necessary to develop the teaching and learning materials and the textbooks using various software. Third, in the major course, the Subject Pedagogy programs should be expanded rather than the subject content programs. Fourth, in the specialization course, the programming language education focusing on the Entry and EPL should be strengthened so that it can be linked with the elementary school curriculum. In addition, it is necessary to expand the choice of subjects for the students by reducing the number of required courses and increasing the number of elective courses.

Reduction of weld distortions and increase in productivity are some of the major goals of the shipbuilding industry. To address these issues, many researchers have attempted to apply new welding processes. In the shipbuilding industry, steel is the candidate material of choice owing to its good weldability. However, conventional welding techniques are not feasible for avoiding welding problems. Tip-rotating arc welding is one of the high-efficiency welding process that has several advantages, such as high welding speed, high melting rate, low heat input, and less distortion. The present study investigates the influence of the welding variables on the weld characteristics of tip-rotating arc welding. Welding was performed using EH36 as the base metal and SM-70s as the filler metal, which are widely used in shipbuilding. Basic experiments were conducted to understand the effects of the major welding variables, such as welding and tip-rotating speeds. The distortion and mechanical properties of the optimal welding conditions were used to evaluate the tip-rotating arc welding performance. Consequently, the feasibility of the tip-rotating arc welding process for joining steel components was investigated, so that the optimized welding conditions could be applied directly to ship body welding to enhance the quality of the welded joints.

Background: This study aims to improve dental hygiene education by investigating the relationship between metacognition, learning flow, and problem-solving abilities in dental hygiene majors. Methods: A survey was conducted on 2nd to 4th-year students from dental hygiene programs, with 132 responses analyzed. Data analysis involved t-tests and ANOVA to examine the differences in metacognition, learning flow, and problem-solving abilities based on the general characteristics. Multiple regression analysis was employed to investigate the factors influencing the dependent variable, which is problem-solving abilities. The collected data were analyzed using SPSS. Results: First, when comparing metacognition, learning flow, and problem-solving abilities based on the general characteristics of the study participants, statistically significant differences were observed in common factors such as major satisfaction, subjective academic performance, GPA (grade point average), and reason for major choice (p<0.05). Second, it was found that there is a significant positive correlation between metacognition, learning flow, and problem-solving abilities in dental hygiene students (r≥0.79, p<0.05). In other words, higher levels of metacognition and learning flow were associated with better problem-solving abilities. Third, factors influencing problem-solving abilities were identified, with both metacognition and learning flow having a statistically significant positive impact. It was also noted that metacognition had a greater influence on problem-solving abilities compared to learning flow (adjusted R²=0.815, p<0.05). Conclusion: To enhance the core competency of problem-solving abilities, it is essential to improve metacognition and learning flow. To enhance metacognition and promote learning flow, strategies such as goal setting, utilizing effective learning methods, boosting self-efficacy, managing the learning environment, choosing activities that foster immersion, stress management, self-assessment and feedback integration, improving focus, and utilization a variety of learning experiences will be necessary.
