Kaempferia parviflora (Krachaidam, Zingiberaceae) is used as a traditional Thai medicine for treating various ailments, including allergy, fatigue, sexual dysfunction, and ulcer. Moreover, it is also used to promote longevity and as a nerve tonic. The aim of this study was to develop functional yoghurt containing Kaempferia parviflora and to examine the physicochemical characteristics of yoghurt supplemented with different concentration of K. parviflora. To this end, we examined the pH and sensory evaluation of yoghurt containing K. parviflora. The pH of this yoghurt decreased whereas the TA increased with incubation time (up to 5 h) without altering the amounts of K. parviflora added. In the sensory evaluation, the taste, flavor, color, and overall acceptability decreased in proportion to the amount of K. parviflora added. Among the experimental group, high scores were achieved by yoghurt containing 1% K. parviflora compared with that by the control group. We conclude there is an urgent need for additional research on the production of this multi-functional yogurt (with properties including anti-obesity and anti-inflammatory), using an optimum concentration of K. Parviflora.

Background: The purpose of the study was to analyze the contents and importance of clinical practicum education in adult health nursing. Methods: This is a descriptive study using content analysis for identifying the items of clinical nursing checklists gathered from 13 university nursing programs accredited by Korean Accreditation Board of Nursing Education. Items in the checklist were standardized in accordance with the Nursing Intervention Classification (NIC) and categorized into simple-technical skill, complex-technical skill, and disease-specific care. The perceived significance of each item was examined by surveying nurses who in charge of nurse education from various clinical setting. Results: A total of 182 items in the clinical practicum contents were analyzed, and the terminologies of each item were variously described among nursing schools. Fifty percent of the total items were categorized into simple-technical skill. In terms of clinical importance, expert validity results showed that nurses considered infection control, infection protection, and fall prevention as the most significant items, which was not the same as the most common items in the clinical nursing checklist. Conclusion: These findings suggest that standardized nursing terminologies are needed to describe a nursing practicum checklist. Clinical importance of each item in the checklist should be taken into consideration in developing a clinical nursing checklist to assist the students in achieving the competencies as a clinical nurse.

Purpose: We aimed to identify collaborative disaster governance through the demand and supply analysis of resources recognized by nurses during the COVID-19 pandemic. Methods: We used a descriptive study design with an online survey technique for data collection. The survey questions were developed based on focus group interviews with nurses responding to COVID-19 and expert validity testing. A 42-question online survey focusing on disaster governance was sent to nurses working in COVID-19 designated hospitals, public health offices, and schools. A total of 630 nurses participated in the survey. Demand and supply analysis was used to identify the specific components of disaster governance during a pandemic situation and analyze priority areas in disaster governance, as reported by nurses. Results: Demand and supply analysis showed that supplies procurement, cooperation, education, and environment factors clustered in the high demand and supply quadrant while labor condition, advocacy, emotional support, and workload adjustment factors clustered in the high demand but low supply quadrant, indicating a strong need in those areas of disaster governance among nurses. The nurses practicing at the public health offices and schools showed major components of disaster governance plotted in the second quadrant, indicating weak collaborative disaster governance. Conclusion: These findings show that there is an unbalanced distribution among nurses, resulting in major challenges in collaborative disaster governance during COVID-19. In the future and current pandemic, collaborative disaster governance, through improved distribution, will be useful for helping nurses to access more required resources and achieve effective pandemic response.

Although ready meals have recently increased their market share in the Korean food industry, a literature review found that the use of ready meals triggers feelings of guilt in homemakers. Such guilt arises as a result of several factors apparently related to consumers' health. Consequently, levels of guilt might be expected to vary depending on consumers' perceived health locus. The present study aims to examine (a) how health locus affects guilty feelings about ready-meal consumption, (b) how the effect varies in relation to the consumption of different types of ready meal, and (c) the relationship between consumers' guilty feelings and willingness to buy ready meals. Three dimensions of health locus of control (HLC) -internal HLC (IHLC), powerful-others HLC (PHLC), and chance HLC (CHLC)- were presumed to influence consumers' feelings of guilt in association with ready meals. Data were collected via an online survey, and participants were randomly assigned to either of two groups: one group was instructed to heat meals in a microwave (ready-to-heat [RTH] group, n=104) and the other cooked using a pan with additional ingredients (ready-to-cook [RTC] group, n=101). The study found that guilty feelings about consuming RTH meals increased in line with increased external HLCs, namely, PHLC and CHLC. For the RTC group, guilt increased in line with increased PHLC. IHLC had no significant effect on guilty feelings in either group. Willingness to buy ready meals decreased for both groups as consumers' feelings of guilt increased. Even RTC meals, which require more time and energy in food preparation, did not reduce guilty feelings among consumers with higher PHLC. RTC meals are preferable for consumers with higher CHLC, since their sense of greater involvement in the cooking process alleviates their feelings of guilt. Cooking with already prepared and uncooked ingredients brought fun and joy, both for the participants and their significant others. This interpretation may be developed into a strategic plan by ready-meal producers to strengthen their marketing strategy.

The purpose of this study is to evaluate the reduction effect of microbially activated peat on odor generated by livestock farms. The odor gas was measured by stirring the livestock manure sample with the existing litter and the microbially activated peat (Healtha Peat) was developed by this research team. In outdoor farm experiment, the measurements were performed by comparing broilers farm using rice husks and microbially activated peat as litter. The weight, mortality, shipment date, and odor levels (NH₃) were measured before and after experiment. The result showed that NH₃ levels were reduced by 100% in the Healtha Peat mixed group, Healtha Peat and rice husks mixed group. In the peat mixed group, Healtha Peat and saw dust mixed group showed reduce value at 99.6% and 99.1%, respectively. However the rice husks mixed group and saw dust mixed group showed a relatively weak NH₃ reduction effect with values of 57.5% and 84.8%, respectively. After 3 months, the Healtha Peat mixed group and Healtha Peat and rice husks mixed group showed the highest NH₃ reduction effect persistence. In the outdoor farm experiment, NH₃ was present in farms using rice husks, but not in farms using Healtha Peat. In farms using Healtha Peat, the mortality and NH₃ were reduced by 75% and >90%, respectively. The average body weight increased 18% and resulted to 10% decrease in the shipping date. These results implied that microbially activated peat has a clear effect on farm NH₃ reduction and affects the productivity of farm animals.
