This study investigated associations between healthy dietary practices and the odds of prediabetes among Korean adolescents. The data of 1,624 adolescents aged 12 to 18 who participated in the 2017-2021 Korea National Health and Nutrition Examination Survey were analyzed. Healthy dietary practices were defined according to Health Plan 2030 criteria, and prediabetes was defined as a fasting blood glucose level of 100-125 mg/dL. After controlling for confounders, adjusting odds ratios and 95% confidence intervals (CIs) for prediabetes were determined for different healthy dietary practices using multivariable logistic regression analysis. Compared with adolescents who engaged in healthy dietary practices, those who did not had a 1.63-fold (95% CI: 1.12-2.37) higher odds of prediabetes. In addition, adolescents who did not consume ≥500 g of fruit and vegetables daily and those who refrained from reading nutritional fact labels, which are both sub-indicators of healthy dietary practices, had a 1.66 (95% CI: 1.05-2.62) and 1.58-fold (95% CI: 1.06-2.37) higher odds of prediabetes, respectively, than those who did. Increasing the proportion of adolescents engaging in healthy dietary practices, such as consuming ≥500 g of fruit and vegetables daily and reading nutritional fact labels when selecting food, is imperative.

Purpose: Falls are one of the most frequent health events in medical institutions, however, they can be predicted and prevented. The Quality Improvement Nurse Society clinical practice guideline Steering Committee developed the Clinical Practice Guideline for the assessment and prevention of falls in adult people. The purpose of this study was to assess the risk factors for falls in adults aged 19 years and older, to present an evidence for preventing falls, formulate a recommendations, and indicators for applying the recommendations. Methods: This clinical practice guideline was developed using a 23-step adaptation method according to the Handbook for clinical practice guideline developer (version 1.0) by National Evidence-based Healthcare Collaborating Agency. Evidence levels and recommendation ratings were established in accordance to SIGN 2011 (The Scottish Intercollegiate Guidelines Network). Results: The final 15 recommendations from four domains were derived from experts' advice; 1) assessment of risk factor for falls in adult 2) preventing falls and reducing the risks of falls or falls-related injury 3) management and reassessment after a person falls 4) leadership and culture. Conclusion: This clinical practice guideline can be used as a basis for evaluation and prevention of fall risk factors for adults, to formulate recommendations for fall risk assessment and fall prevention, and to present monitoring indicators for applying the recommendations.

4차 산업혁명시대의 도래로 인해 현대사회는 과거와 다르게 경제, 경영, 문화 등 다양한 요소들이 변화하고 있다. 그 중 경영적 측면에서 나타나는 주된 특징은 유형재화 중심에서 무형재화 중심으로 변화하는 것이며 이에 기업들은 새로운 경영방식 도입, 제조에서 서비스로의 전환, 기술의 확장 등 혁신을 추구하기 위해 노력 하고 있다. 하지만 변화하는 시대 지속적 가치창출을 위해 가장 중요성이 높아지고 있는 인적자원에 관해서는 아직까지 단순한 방식의 전환에 머무르고 있어 실질적인 혁신을 가능케 하는 노력이 부족한 실정이다. 이에 본 연구에서는 서비스경제시대 새로운 인재상에 대한 기업에서의 활용성을 검증하고자 인재요소에 대한 중요성을 인식하고 기존 도출 된 서비스경제시대에 변화된 인재상 요소들이 조직문화와 조직구조의 유형에 따라 어떠한 관계와 차이가 있는지를 연구하였다. 최근 연구에서 도출, 검증 된 서비스경제시대 인재상요소를 활용하여 구성원들의 생각과 행동에 영향을 주는 요소인 조직문화와 조직구조의 유형으로 나누어 관계를 검증하였으며 그 결과 조직문화와 조직유형별로 유의미한 인재상에 다소 차이가 있었으나 두 가지 요소를 결합하여 해석하였을 경우에는 새로운 인재상이 모두 유의미한 것으로 나타났으며 이는 서비스경제시대 인재상이 실제 기업에 적합하다는 것으로 해석될 수 있다. 다만 본 연구의 지표가 한정적 이었다는 한계를 극복하기 위해 향후 다양한 요인들이 고려 된 표본과 체계화 된 조직유형 및 업종별 산업별 분류를 통한 연구가 지속적으로 이어져야 할 필요가 있다.

Purpose - The objective of this research is to investigate whether national culture influences consumers' service evaluations. The services industry is receiving increasing attention from academia and practitioners as its position grows in global markets. Standardization or localization is a traditional managerial decision in global business. As the boundaries of services expand across national borders, firms are required to decide whether to standardize services or adjust to local needs. Though it is imperative to reflect global perspectives in marketing theories, these perspectives are mostly based on Western conceptualization of the world. Through a comparison of consumer groups from two culturally remote countries, service quality evaluation mechanisms are examined based on similar stimuli. The study tries to expand service marketing perspectives across national borders. Research design, data, and methodology - Eastern and Western countries are known to be culturally distinct. One Eastern and one Western country were chosen: an Anglo-Saxon country (the U.S., England, and Australia) and South Korea. In Hofstede's cultural dimensions, the differences between the two are pronounced. The Anglo-Saxon based countries share many similarities. Samples of the same sites are targeted. Questionnaires using a service quality scale (SERVQUAL) and a customer satisfaction scale were distributed. Utilizing Hofstede's typology of culture, the service evaluation mechanisms of the respondents from the two groups are evaluated. Three hypotheses are proposed from the review of the literature. These are service evaluation habits, importance of service quality dimensions for the individualistic/collectivistic countries, and strong/weak uncertainty avoidance cultures. Consumers from the individualistic countries are considered to care about themselves and demand a higher level of responsiveness and assurance. On the other hand, consumers from high uncertainty avoidance cultures are assumed to rely more on tangible questions of service quality, as these are the only predictable service quality indicators. A t-test and regression analysis are applied to validate the constructs. Results - The respondents from the Anglo-Saxon countries are more generous on service evaluations than Koreans. Researchers have indicated that Americans tend to give higher service evolution scores than European, Mexican, and Korean counterparts. The tendency is the same here. The sample from Anglo-Saxon countries demonstrated higher service evaluation scores on every dimension of SERVQUAL. For the second hypothesis, the respondents from the collectivistic culture rely less on core service dimensions (assurance and responsiveness) due to their tendency to place more value on group harmony than individual interest. However, the third hypothesis was not validated. Conclusions - The study attempted to expand the scope of service marketing to reflect cross-national perspectives. Service quality is known to have a strong influence on customer satisfaction and loyalty behavior. However, this research demonstrated that individuals from different cultural territories respond heterogeneously to the same stimuli. Scholars argue that national cultures are main factors in such deviated behavior. Scholars and global managers should be aware of differences in consumer value judgment mechanisms such as satisfaction, expectations, and perceptions.

Leaf color and plant vigor are key indicators of crop health. These visual plant attributes are frequently used by greenhouse managers, producers, and consultants to make water, nutrient, and disease management decisions. Remote sensing techniques can quickly quantify soil and plant attributes, but it requires humans to translate such data into meaningful information. Over time, scientists have used reflectance data from individual wavebands to develop a series of indices that attempt to quantify things like soil organic matter content, leaf chlorophyll concentration, leaf area index, vegetative cover, amount of living biomass, and grain yield. The recent introduction of active sensors that function independent of natural light has greatly expanded the capabilities of scientists and managers to obtain useful information. Characteristics and limitations of active sensors need to be understood to optimize their use for making improved management decisions. Pot experiments involving sand culture were conducted in 2003 and 2004 in a green house to evaluate corn and red pepper biomass. The rNDVI, gNDVI and aNDVI by ground-based remote sensors were used for evaluation of corn and red pepper biomass. The result obtained from the case study was shown that ground remote sensing as a non-destructive real-time assessment of plant nitrogen status was thought to be a useful tool for in season crop nitrogen management providing both spatial and temporal information.

The article assesses the functioning of the DE system or a separate educational institution, where it can be carried out on the basis of developed criteria or on a regulatory basis. The assessment was carried out on the basis of a qualitative and quantitative nature by comparing the actual state of affairs with a certain "ideal" (educational standard), which must be defined and used as a kind of benchmark against which the assessment is made. Conducted an assessment based on a regulatory framework that represents an alternative approach. It has been emphasized that the exceptional difficulty in determining the ideal indicators (norms) of the activities of universities, it has been found that the normative approach, in which the activities of traditional and open universities are compared, taking into account the differences in social, cultural and economic conditions, is the most acceptable.

It has been reported that tight sportswear could have complicated influence on physiological function of human body. The purpose of this present study was to investigate the effect of wearing gradient compression tights (GCT) on muscle strength and EMG activity during repeated isokinetic muscle contractions. Four healthy male undergraduate students performed maximal voluntary isokinetic concentric muscle contractions on biomechanical test and training systems with GCT and loose pants as control (Cont) respectively. During each test, the peak torque of extensor and flexor contractions and the surface electromyography (sEMG) of the rectus femoris and medial gastrocnemius was recorded simultaneously, the peak torque was recorded as an indicator of muscle strength, and the average amplitude and mean power frequency of sEMG were calculated as indicators of EMG activity. The results showed that: the peak torque decreased gradually during continuous muscle contractions both when the Cont and GCT were worn, average sEMG and mean power frequency declined along with the repetitions of muscle contractions for both wearing conditions, and the change tendency was consistence with that of peak torque. There was no obvious difference between the peak torque recorded wearing the Cont or wearing GCT, but when GCT were worn, average sEMG was lower and mean power frequency was higher than the Cont condition. In 24 samples obtained from four subjects, 80% of results showed the same trend. So we could make a conclusion that wearing GCT had no obvious effect on the improvement of muscle strength, but it would affect the EMG activity positivly.

This study intended to propose an improvement plan to improve user satisfaction by establishing a park and green space masterplan by comparing its current status and surveying the residents' perception of green park services in two regions. The study results showed that the residents are aware of the physical and qualitative aspects of the green park environment. In addition, the quality level of the green park that people may actually use in everyday life was considered a factor for evaluation of satisfaction. In addition, it was found that the residents, who are actual users of the green park services, evaluated the satisfaction of use considering the qualitative characteristics of the green park, such as 'quality of green park' and 'availability of green park.' As a result, efforts are required to create and improve the quality of green parks efficiently based on establishing qualitative indicators, a survey of residents' perception, and quantitative analysis to develop policy directions and guidelines of the park and green space masterplan.

The purpose of this study was to analyze the current operating management practices and tourist royalty of restaurants at the tourism provinces in Donghae city. Forty restaurants were surveyed for sales status, customer management, menu management, advertising, marketing strategy and seventy seven tourists replied to the attitudinal and behavioral aspects of customer royalty for regular visiting restaurant. Statistical data analyses were completed using the SPSS/WIN pact(age program for descriptive analysis, paired difference test, t-test, ANOVA, and pearson correlation. The results of quantitative analysis indicated that the average sales per day on a high-demand season were 1,571 thousand won and one on a slack season were 614 thousand won. The average check on a high-demand season(109 persons) and a slack season(38 persons) were significant difference(t=6.834, p<.001). A total of 93.5% of the restaurateurs answered that menu pricing was decided by the owner and 21.7% of the subjects used the only restaurant homepage in the advertising method. A total of 40.6% of the restaurants utilized the only kind service for regular customers and 35.1% of the subjects had no method for them. The results suggest that systematic management policies and marketing strafes for regular customer is very necessary. Also, the correlation between tourists' attitudinal and behavioral aspects of customer royalty for regular visiting restaurant was found out. High correlation was existed between the overall tourists' satisfaction on regular visiting restaurant, the intention to revisit(BCL 1, p<.001), the intention to recommend(BCL 2, p<.001), and indicators of customer royalty. Finally, restaurateurs at the tourism provinces should focus on marketing strategy to keep and improve current customer to rise the tourist royalty.
