The study entitled “A Case Study: Patterns of Freshman Welcoming Activities at Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon” a mixedmethod research aims to investigate the patterns effects and students ’attitudes towards freshman welcoming activities. The participants in this study were the first- to the fourth-year university students from four majors including Applied Thai English for International Communication Hotel Management and Tourism. The participants can be divided into two groups: the participants of freshman welcoming activities (the first-year university students N = 132) and the organizers (the second-year to the fourth-year university students N = 65). The participants were 197 university students in total. The research instruments used for data collection were questionnaire and depth interview questions. For the questionnaire it can be divided into four parts: Part I concerning general information Part II and III related to types of welcoming activities and students’ attitudes towards the freshman welcoming activities organized in the Faculty of Liberal Arts at Rajamangala University of Technology Phra Nakhon and Part IV providing suggestions. Thirty voluntary participants were asked to provide in-depth information about freshman welcoming activities organized the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. The data obtained from the questionnaires were analyzed by using descriptive statistics: frequency percentage means and standard deviation. The data obtained from the in-depth interview were transcribed and analyzed by using textual analysis. Most participants in this study were female university students whose age group was 19 years old. The participants filled in their answers from 1 to 5 that is 5 strongly agree 4 agree 3 neutral 2 disagree and 1 strongly disagree to report their attitudes towards the freshman welcoming activities organized in the Faculty of Liberal Arts at Rajamangala University of Technology Phra Nakhon. The results of the study show that the participants highly agreed with the appropriateness and the types of freshman welcoming activities responding to the goals. The participants also added that they wanted to have a welcome feast (71.6%) followed by Baisri Sukwan welcome ceremony (64%) and booming activity for welcoming the new first-year university students (55.8%) respectively. The results of the study showed the participants ’awareness of security and willingness while taking part in the freshman welcoming activities. The students mostly agreed with positive effects of participating these kinds of activities: building relationship unity and responsibility. However they also moderately agreed that these activities could provide negative effectives: individual and organizational damage (for example losing publica image) According to the descriptive analysis and textual analysis the results showed that these university students were willing to take part in freshman welcome activities indicating that the activities were suitable supervised by related departments. They also suggested that there should be welcome activities based on their interests and suggestion box to achieve the goal. However one of the limitations of the study was the widespread of coronavirus resulting in the average score and standard deviation in some questionnaire items.

This research aimed to 1) To analyze the basic understanding and awareness of household waste separation. 2) To study the guidelines for the development of activities to raise awareness of waste separation in the household and 3) To practically benefit to raising social awareness from group activities. The sample used for this research was school students with education level lower than bachelor’s degree in Bangkok and vicinity. In-depth Interviews were used to collect data from 35 students. The research found that Attitude – According to comments from students during group activities they had the attitude towards the household waste separation at the highest level because the waste separation behavior reduces pollution and makes the environment cleaner. Personal Norm to follow all the survey questions was at a moderate level as 1) parents expected them to engage in waste separation behavior 2) friends expected them to engage in waste separation behavior and 3) friends placed importance on engaging in waste separation behavior. Perceived behavioral control to put into practice was at a high level due to 1) waste separation is easy and 2) being confident that waste can be separated on a regular basis. Intention – Students had a high level of intention to practice 1) Students were willing to separate the waste if there is an appropriate waste separation spot. 2) Students planned to separate the waste if appropriate waste separation spots are available. 3) Intended to separate their household waste on a regular basis. The results were used as a guideline for the development of activities activity development creating interest in activities. All of which were necessary to be environmentally focused and to lead to the storytelling to create continuity of activity. Recommendations – If possible the development of activities to raise awareness in the household for students and for parents should be integrated because parents have a significant influence in setting an example for target students.

The potential health benefits attributed to mulberry leaf and its bioactive compounds have led to a huge increase of mulberry leaf products in the food market. The objective of this research was to determine total antioxidant activities ( FRAP and DPPH assays) and polyphenol compounds in 4 snack products i.e. loaf-bread puifai (Thai steamed cupcakes) peakpoon (Green coconut sweet pudding) and snow skin mooncake fortified with 10% mulberry leaf powder from “ Buri Rum 60” cultivar. The result showed that antioxidant activities and polyphenol contents increased in 4 products fortified with mulberry leaf powder. Ferulic acid was the only phenolic compound found in all original products. Kaempferol quercetin and caffeic acid were significantly increased whereas ferulic acid was reduced in the modified formulas. Therefore these bioactive compounds properties of mulberry leaf powder suggested their possible use for fortifying the healthy foods.

This study investigated the effects of partial replacement of wheat flours with Hom Nil rice flour on the physicochemical characteristics antioxidant activities and sensory acceptance of chinese steam bread (Mantou). Mantou was made with wheat flours partially substituted with Hom Nil rice flour at the level of 0% 10% 20% and 30%. Colour parameters (lightness (L*) redness (a*) and yellowness (b*)) of Mantou were measured using a Hunter colorimeter and found that L* andb* values of Mantou decreased while a* value increased with increase in level of Hom Nil rice flour from 0 to 30%. Physical characteristics including hardness springiness and cohesiveness of Mantou were significantly affected with substitution due to the disruption of dough structure. The hardness of Mantou increased with the increasing of the Hom Nil rice flour substitution (0%-30%) in contrast with springiness and cohesiveness. The total phenolic/anthocyanin contents and antioxidant activities (DPPH FRAP and ABTS) of Mantou increased with increasing Hom Nil rice flour level up to 30%. These results suggested that the substitution of 20 % Hom Nil rice flour would produce healthy and acceptable Mantou with higher total phenolic/anthocyanin contents and antioxidant activities.

The aim of this research was determine total phenolic content total flavonoid content and antioxidant activity by DPPH and ABTS assay from leaves flower and stem of Crateva adansonii DC. subsp. trifoliate (Roxb) Jacobs that was extracted by Soxhlet method using ethanol dichloromethane and ethyl acetate as solvent. Leaves extract showed the highest total phenolic content and antioxidant activity. Ethanolic leaf extract showed the highest total phenolic content (157.13±0.32 mg GAE/g extract) and antioxidant activity by DPPH assay (53.64±3.78% (IC50 = 1.49±0.02 mg/ml)) and ABTS assay (76.51±0.97% (IC50 = 0.84±0.01 mg/ml)).When we considering solvent effect found that ethanolic extract showed the highest total phenolic content and antioxidant activity. Total flavonoid content ethyl acetate extract showed the highest total flavonoid content. Total phenolic content significantly correlated with antioxidant activity.
