Objective: This study was conducted to assess the current status of experiential education, by analyzing pharmacy students' satisfaction and evaluation for practice sites and preceptors for 3 years from 2014 through 2016. Methods: Students evaluated the practice sites and preceptors using a 5-point and a 4-point Likert scale, respectively. Analysis was performed based on the types of curriculums and practice sites. In addition, sub-analysis was conducted based on the types of health-system pharmacy and the community pharmacy. Results: Total 203 students responded to the survey questionnaires. The 3-year average score of students' satisfaction with practice sites was 4.25. In the sub-analysis conducted based on the types of health-system pharmacy, the score was higher in the tertiary hospital pharmacies than that of the general hospital pharmacies (4.49 vs. 4.06, P<0.001). For community pharmacy, the difference in the score of the 3-year analysis was not significant, depending on the types (4.51 vs. 4.33, P=0.054). The average score of students' evaluation on the preceptors was 3.37 in the 3-year analysis. The score was significantly higher for the preceptors of tertiary hospital pharmacies than those of general hospital pharmacies (3.61 vs. 3.25, P<0.001). For community pharmacy, no significant differences were found, depending on the types of pharmacy (3.53 vs. 3.43, P=0.309). Conclusion: The students' satisfaction with practice sites and preceptors in pharmacy experiential education was high. However, it varied greatly depending on the types of educational institutions.

The pitch range of the human voice is variable, extending from chest register to falsetto. Although numerous studies have investigated after laryngeal mechanism description of registers, systematic and objective studies were lack. The purpose of this study was to analyze and compare head register with chest register of singers acoustically. Fifteen healthy tenor major students were selected. Fifteen healthy untrained adults were the control group for this study. Long term average(LTA) power spectrum using the Fast Fourier transform(FFT) algorithm and Linear predictive coding (LPC) filter response were made during /a/ sustained in both head(G4, 392Hz) md chest registers (C3, 131Hz). Statistical analysis was performed using Mann-Whitney test. In the LTA power spectrum, head register of singer has increased level(energy gain) in the frequency band of 2.2-3.4kHz(p<0.01), and 7.5-8.4kHz(p<0.01, p<0.05). Chest register of singer has increased level in the frequency band of 2.2-3.1kHz(p<0.01), 7.8-8.4kHz(p<0.05) and around 9.6kHz(p<0.01). LTA power spectrum reveals a peak of acoustic energy around 2500Hz known as the singer's formant and another peak of acoustic energy around 8000Hz in singer's voice.

This study was performed to find out the quality characteristics of Noodles by addition of red ginseng powder(0, 2, 4, 6, 8%). The quality characteristics of the sample were estimated in terms of general com-position, color difference, cookery characteristics(water absorption, volume of cooked noodles, turbidity), texture profile analysis and sensory evaluation. The protein, lipid, ash, Na and water binding capacity did not show significant difference in any of the groups. In red ginseng powder added groups, moisture contents, a and b values significantly increased but L value considerably decreased(p<0.05). The weight, volume, water absorption of the cooked noodles and turbidity of 8% of red ginseng powder added group were significantly higher than the control group(p<0.05). In texture profile analysis, adhesiveness, gumminess, hardness and springiness significantly decreased(p<0.05) with more red ginseng powder added. Chewiness and cohesiveness significantly(p<0.05) increased with the 4, 6, 8% of red ginseng powder added. In sensory evaluation, surface color was very good in the 8% red ginseng powder added group while taste and flavor of red ginseng were very good except the 8% red ginseng powder added group(p<0.05). Appearance and overall quality were highest in the 4% red ginseng powder added group(p<0.05). Therefore, noodles containing 4% red ginseng powder were most preferable.

Objectives : The study was to examine the empirical evidence concerning the effects of massage intervention for the laboring women and to investigate the effect sizes related to the characteristics of intervention. Methods : Meta analysis was performed. A total of 11 trials related to massage intervention between 2000 and 2007 were reviewed. Results : Massage intervention showed a beneficial effect on length of labor(1st stage : U=46.75, p=0.00, 2nd stage : U=6.13, p=0.01), perception of childbirth experience(U=12.57, p=0.00), intensity of uterine contraction at the active(U=6.34, p=0.01) and the transition phases(U=24.83, p=0.00), and interval of uterine contraction at the active phase(U=4.83, p=0.03). Massage decreased systolic(U=10.81, p=0.00) and diastolic blood pressure at the transition phase(U=10.60, p=0.00). However, massage had no effect on subjective and objective labor pain and anxiety. No differences were found in effectiveness of massage according to characteristics of intervention(massage material, massager, and massage site) except for anxiety(QB=4.82, p=0.03) and diastolic blood pressure at the active phase by massage site(QB=4.52, p=0.03). Conclusions :We found that massage intervention for the laboring women had an empirical evidence on improving perception of childbirth experience and shortening length of labor. These results should be interpreted with caution due to the lack of studies. More full-scale randomized clinical trials with reliable designs are recommended to further warrant the effectiveness of massage.

This study was a cross-sectional descriptive investigation study that analyzed the effects of spiritual well-being on stress coping in twenties. Data collection period was from May 1, 2019 to May 20, and 207 people voluntarily participated in the study. The sub-factors of spiritual well-being consisted of religious well-being and existential well-being. The types of stress coping consist of active coping, passive coping, aggressive coping, evasive coping, and social supportive coping. Data was analyzed using frequency analysis, t-test, Pearson correlation and multiple regression analysis using SPSS 18.0. As a result of the analysis, 90 (43.5%) were male and 117 (56.5%) were female. The 71.0% of the participants had no religion, the Buddhists were 14.5%, other religions were 5.8%, Protestants were 4.3%, Catholics were 2.9%, and Won Buddhists were 1.4%. Active coping in stress coping was correlated with religious well-being (r=-.357, p<0.01) and existential well-being (r=.301, p<0.01) under statistical significance. Religious well-being was significantly higher in males (Mean=2.87, SD=.753) than females (Mean=2.49, SD=.772, p<0.01). Existential well-being was also higher in males (Mean=4.25, SD=.841) than in females (Mean=3.95, SD=.694, p<0.01). The religious well-being was significantly higher than active coping (t=6.183, p<0.01), passive coping (t=-3.595, p<0.01), aggressive coping (t=1.991, p<0.05). Existential well-being was significantly higher than active coping (t=5.339, p<0.01), aggressive coping (t=1.659, p<0.05), evasive coping (t=-3.709, p<0.05) at the statistical significance level. Based on the results, it can be suggested that it was necessary to systematically plan spiritual well-being program as a way to cope with stress by knowing that spiritual well-being positively affects active, aggressive stress coping.

Purpose: This study examined the meal-kit consumption practices of adults in their 20s and 30s and analyzed the properties that should be given priority for improvement among the selection attributes to improve the quality of meal-kits. Methods: Statistical analyses were conducted using the SPSS program (ver. 28.0) for χ²-test, t-test, one-way analysis of variance, Duncan's multiple range test, factor analysis, and Importance-Satisfaction Analysis (ISA). Results: Of the 249 subjects surveyed, 85.5% had some experience of purchasing meal-kits, with significantly more females than males (p < 0.01), significantly more married people than single people (p < 0.05), significantly more employed people than unemployed people (p < 0.05). Meal-kits were purchased most frequently for meals (60.6%), from discount stores or supermarkets (44.6%), and priced between 10,000 won and 20,000 won per person (46.9%). The overall satisfaction with meal-kits was 4.1 out of 5.0 points. The frequency of purchases was Korean soup dishes (69.5%), Korean main dishes (47.4%), and Korean street snacks (46.9%). Factor analysis of the meal-kit selection attributes revealed, 4 factors: 'quality of food,' 'packaging and diversity,' 'quality of meal-kit,' and 'convenience and price.' Compared to single-person households, multi-person households placed significantly higher importance on the 'quality of food,' 'packaging and diversity,' and 'quality of meal-kit.' The factor, 'packaging and diversity' were significantly higher in the importance evaluation scores for females (p < 0.01), married people (p < 0.05), and people in their 30s (p < 0.05) among meal-kit consumers. According to the ISA results, a critical aspect that meal-kit manufacturers or sellers should strengthen is 'price.' Conclusion: Meal-kit products will need to be developed for various purposes that offer high value for money that can satisfy the consumers' needs to improve the satisfaction of meal-kit consumers.
