This feeding trial was conducted to investigate the effects of Mentha arvensis (MA) and Geranium thunbergii (GT) in drinking water on physicochemical attributes, sensory qualities, proximate analysis and oxidative stability of broiler leg meat. One hundred and twenty broiler chicks were assigned to 1 of 4 dietary treatments for 5 weeks. The dietary treatments were 1) control, 2) T1 (0.1% 1 MA:1 GT), 3) T2 (0.1% 1 MA:4 GT), 4) T3 (0.1% 4 MA: 1 GT). The water holding capacity and cooking loss were improved (p < 0.05) in T2 and T3. The flavor, texture and acceptability of leg meat by consumers were significantly increased in T2 relative to the control (p < 0.05). The crude protein content was increased in T3 while the crude fat decreased in T2 (p < 0.05). Moreover, broilers supplemented with plant extracts had the lowest leg meat TBARS (thiobarbituric acid reactive substances) values after 2 weeks of storage as compared with the control. Total phenolic contents and 1-1-diphenyl 2 picrylhydrazyl (DPPH) activity were also better in the T2 group (p < 0.05) compared with the control, whereas 2,2-Azinobis-3 ethytlbenzothiazoline-6-sulfonic acid (ABTS⁺) remained unaffected. Overall, these results demonstrate that broiler drinking water with the inclusion of plant extract combination can be used to enhance the oxidative stability, shelf life and quality characteristics of broiler leg meat without compromising the growth performance.

With the dynamically changing environment of society, managing change is the vital element of organizations's survival and growth. Health care organizations have expended enormous resources to restructure patient care delivery. Despite the growing literature describing these organizational innovations, there is a paucity of credible data that reflects systematic measurement and evaluation of such changes. This study examined the nurses' psychological response toward the work process redesign, newly introduced by the nursing department in a acute care hospital. The aim of the study was to figure out how nurses's general perception of change and perceived attributes of change affected their acceptance of change during the organizational transition. This was descriptive- correlational. The sample for the study included 50 head nurses and 135 staff nurses. Data was analyzed using SPSS PC+, version 10.0. The major findings of the study were as follows: First, the mean score of the perception of change was 71.2(SD=13.8) with the range of 0-100, which means nurses generally perceived change positively. There were significant differences in perception of change by gender and education level. Head nurses perceived change more positively than staff nurses. The higher education level showed the more positive view of change. Second, among the perceived attributes of change, trialability had the highest mean score, which means nurses perceived the change more positively if it is testable on a limited basis. Relative advantage was perceived the most negatively. Finally, factors influencing the acceptability of the work-process redesign were perceived comparability, complexity, relative advantage, and observability, which accounted for 43.7% of the variance in the acceptability of change. This study evaluated the preliminary effects of the nursing process for reengineering, focusing on nurses' acceptability towards change. The usefulness of this research study was to determine the factors influencing acceptance of organizational members during transitional periods of change and to suggest effective strategies for increasing adoption as well as for decreasing resistance to change.

Advances in healthcare technology and rapid economic growth lead to the increased life expectancy and consequently the size of elderly population. Korea is one of the countries that are rapidly aging. Thus, it is particularly important to prepare for the aging society. Recently, the number of healthcare institutions for the elderly citizens has increased. The purpose of selecting a hospital for the elderly is, in general, maintenance of health rather than improvement of health receiving proper treatment. Unlike choosing a hospital for treatment, customers of a long term care hospital have a different set of factors to consider. Especially, when choosing a long term care hospital, the influence of patient's family is greater than the patient. This study examines the factors they consider for long term care hospital. A total of 198 questionnaires were collected from the families of actual patients of long term care hospitals. Twelve questionnaires were found to be non-usable because of missing and unsatisfactory responses. Consequently, 186 questionnaires were used for the analyses. Findings of this study are as follows. First, seven factors have been identified to consider when choosing a long term care hospital for the elderly. They include convenience of facilities, costs variety of facility programs, service hours, reputation, accessibility, quality of medical staff, medical facilities, and facility size. Second, This study measured both importance and satisfaction with these attributes and analyzed the difference between them. Satisfaction was lower than importance in the categories of convenience of facilities, costs, and programs, and accessibility. On the other hand, satisfaction was higher in terms of service hours, reputation, and quality of medical staff. Finally, the current study found positive impact of accessibility and quality of medical staff on reuse intention of a long term care hospital.

This study analyzed what premium features significantly affect customer satisfaction and their recommendation, and what factors significantly affect product attributes. In the process, first, the loyalty program and the customer compensation program were studied to determine the impact of the customer satisfaction and recommendation. The study analyzed that quality and design of product properties had significant effects on all factors, but the brand was not significantly affected. Second, while superiority, differentiation and scarcity of luxury items are significant to customer satisfaction but superiority is only significant in relation to recommendation intention. Third, the preceding study shows that the customer compensation program has a significant impact on sales growth, but the study found that it was not for imported luxury car customers. Fourth, if the royalties program is low in awareness, it has been analyzed that the scarcity and customer satisfaction relationships among luxury goods have been adjusted. On the contrary, if there is a high level of awareness, it is analyzed that there is a control effect customer satisfaction and differentiation among luxury brands. In the conclusion, in order to satisfy customers at the import luxury car market, the differentiation of luxury goods by standard index must be strengthened and the brand must be strengthened among the attributes of the product. In addition, by raising awareness of the royalties program, the relationship between differentiation and customer satisfaction can be enhanced.

The online fashion market in the 21st century has shown rapid growth. Against this backdrop, using consumer activity data to provide customized customer services has emerged as a viable business model that draws attention. Algorithm-based personalized recommendation services are a good example. But their application in fashion products has clear limitations. It is not easy to identify consumers' perceptions of the attributes of fashion, which are various, hard to define, and very sensitive to trends. So there is a need to compile data on consumers' underlying awareness and to carry out defined research to increase the utilization of such services in the fashion industry and further engage consumers. This research aims to classify the attributes and types of fashion products and to identify consumers' perceptions of a given situation where a recommendation service is offered. To find out consumers' perceptions of and satisfaction with recommendation services, an online and mobile survey was conducted on women in their 20s and 30s, a group that uses recommendation services frequently. A total of 455 responses were used for analysis. SPSS 28.0 was used, combined with Conjoint Analysis and multiple regression, to analyze data. The study results could provide insights into a better understanding of recommendation services and be used as basic data for companies to identify consumers' preferences and draw up a detailed strategy for market segmentation.

조기 초관폐쇄성(rapid canopy closure, RCC) 또한 벼의 유전적인 잠재수량성을 향상시킬 수 있는 생리적 특성 중 하나이다. EGV(early growth vigor)가 상이한 22개 품종을 선정하여 EGV와 초관의 조기폐쇄성(RCC)과의 관계, RCC와 생육 및 수량간의 관계를 평가하고자 포장실험(이앙재배)을 실시하였다. 초관이 폐쇄되기 전의 생장은 $y\;=\;{\alpha}{\cdot}{\exp}({\beta}{\cdot}t)$와 같은 지수생장함수로 표현되는데, y는 엽면적지수(LAI) 또는 지상부건물중(DW)이고, t는 적산온도이며, $\alpha$는 지수생장초기의 LAI나 DW 값이고, $\beta$는 지수생장이 일어나는 시기의 LAI 또는 DW의 상대생장률(relative growth rate, RGR; $^{\circ}C^{-1}$)이다. 1. 벼의 지수생장 초기단계에는 품종의 LAI나 DW가 $\alpha$와 높은 정의 상관이 있었고 또한 종자 무게(천립중)와 정의 상관이 있어 종자무게에 의하여 생육이 크게 영향을 받았으며, 그 후의 시기는 품종의 LAI 및 DW가 $\beta$와 높은 상관을 보였다. 2. $\alpha$와 $\beta$는 모두 품종간에 유의적인 차이가 있었다. 3. $\beta$는 단위면적당 영화수 및 수량과 높은 정의 상관을 보였다. 4. 결론적으로 EGV 및 RCC는 상호 밀접한 관련이 있고, EGV가 크면, RCC도 커서 수량에 정의 방향으로 영향을 하는 것으로 판단되었다.

Drought is a major abiotic factor and has drastically reduced crop yield globally, thus damaging the agricultural industry. Drought stress decreases crop productivity by negatively affecting crop morphological, physiological, and biochemical factors. The use of drought tolerant bacteria improves agricultural productivity by counteracting the negative effects of drought stress on crops. In this study, we isolated bacteria from the rhizosphere of broccoli field located in Daehaw-myeon, Republic of Korea. Sixty bacterial isolates were screened for their growth-promoting capacity, in vitro abscisic acid (ABA), and sugar production activities. Among these, bacterial isolates YNA59 was selected based on their plant growth-promoting bacteria traits, ABA, and sugar production activities. Isolate YNA59 highly tolerated oxidative stress, including hydrogen peroxide (H₂O₂) and produces superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) activities in the culture broth. YNA59 treatment on broccoli significantly enhanced plant growth attributes, chlorophyll content, and moisture content under drought stress conditions. Under drought stress, the endogenous levels of ABA, jasmonic acid (JA), and salicylic acid (SA) increased; however, inoculation of YNA59 markedly reduced ABA (877 ± 22 ng/g) and JA (169.36 ± 20.74 ng/g) content, while it enhanced SA levels (176.55 ± 9.58 ng/g). Antioxidant analysis showed that the bacterial isolate YNA59 inoculated into broccoli plants contained significantly higher levels of SOD, CAT, and APX, with a decrease in GPX levels. The bacterial isolate YNA59 was therefore identified as Variovorax sp. YNA59. Our current findings suggest that newly isolated drought tolerant rhizospheric Variovorax sp. YNA59 is a useful stress-evading rhizobacterium that improved drought-stress tolerance of broccoli and could be used as a bio-fertilizer under drought conditions.
