Purpose : The 2020 Dietary Guidelines Advisory Committee specifically noted that meal frequency is associated with risks for cardiovascular disease, type 2 diabetes, and all-cause mortality, although the current evidence on meal frequency is conflicting. As meal frequency itself is affected by various factors, the aim of the study was not only to examine its relationships with cardiometabolic risk but also to identify the mediating effects of dietary quality. Methods : This study used a descriptive correlational design. In all 8,141 healthy adults participated in the study. Measurements included meal frequency, cardiometabolic risk, and diet quality. Data were analyzed using descriptive statistics, Pearson's correlation coefficient analysis, and process macro bootstrapping model 4. Results : The meal frequency was 3.52±0.61 times per day, the risk of cardiovascular metabolic diseases was 0.01±0.61 points, and the diet quality was 62.08±13.87 points. In mediation analysis, the effect of meal frequency on cardiometabolic risk score was completely mediated by diet quality. Conclusion : Improved diet quality in healthy adults should be considered when designing meal frequency interventions aimed at reducing their cardiometabolic risk, as the effect of meal frequency support on cardiometabolic risk was found to be mediated by diet quality.

A subjective index of sound quality when it hit him is required since human listening is very sensitive and complex. Sound quality evaluation it leads consequently rightly in each situation and it composes a sound quality factor. But one of the levels in interest frequency range is substitute we cannot see the tendency of frequency substitute at whole that is executes a clear voice evaluation. Design of experiment is used and dividing 12 equally in frequency domain, the sound quality using sharpness and annoyance is performed by modifying each of frequency domains. Design of experiment method reduces much number experiment very effectively and each main effect of domain solution analysis, such as a case of sharpness and annoyance, the change of domain (increase and decrease of sound pressure level, or change nil) can grasp a type of effect should have influenced to a sound quality, and it will be able to select the objective frequency domain which hits to the sound quality. Through these obtained results the physical changes of level at arbitrary frequency domain sensitivity can be adapted.

Since human listening is very sensitive when the sound hit him, the subjective index of sound quality is required. Therefore, at each situation of sound evaluation its composed with the sound quality factor. But, when substituting the level of one frequency band we could not see the tendency of substitution at whole frequency band during the sound quality evaluation. In this study a design of experiment is used. The frequency domain is divided into an equally 12 parts and each level of domain whether is given increase or decrease due to the change of frequency band based on 'sharp' and 'annoy' of the sound quality is analyzed. By using the design of experiment the number of test is reduce very effectively by the number of experiment and each band the main effect will be as a solution. The case of sound quality for 'sharp' and 'annoy' at each band, the change of band (increase or decrease of sound pressure or keep maintain) which will be the most effects on the characteristics of sound quality can be identify and this will be able to us to select the objective frequency band. Through these obtained results the physical changes of level at arbitrary frequency domain sensitivity can be adapted.

Background: This research was planned with the aim of determining the effect of symptom frequency of children with cancer on the quality of life of their parents. Materials and Methods: In gathering the research data, the Child and Parent Information Form, the Symptom Evaluation Form and the Family Version of Life Quality Scale in Cancer Patients were used. Evaluation was made by using percentage calculations, Kruskal Wallis test, Bonferroni adjusted t-test and Bonferroni adjusted Mann-Whitney U test. The significance level was accepted as 0.005. Results: Some 37.6% of the participant children were female and 62.4% were male, with an average age of $10.2{\pm}4.5$. While 41.0% were newly diagnosed, 46.2% were in remission and 12.8% was in relapse. Highly significant differences were detected according to the symptom frequency with parent physical and psychological health, social anxiety, and spiritual wellness sub-dimensions, as well as total point averages. Conclusions: It is thought that following up the symptoms that might develop depending on cancer diagnosis and treatment and implementing nursing initiatives aimed at reducing the symptoms, knowing the importance of life quality, maintaining measures aimed at life quality and planning initiatives to increase the life quality will play a key role in maintaining and developing the health of Turkish paediatric oncology patients and their parents.

In this letter, the effect of quality factor on center frequency deviation in miniaturized coupled line bandpass filter (BPF) with diagonally end-shorted at their opposite sides and lumped capacitors is theoretically analyzed. The miniaturized BPF of a two-stage structure with two types of quality factors in standard CMOS process was designed and manufactured at 5.5 GHz. The die area of BPF was $1.44{\times}0.41\;mm^2$. The measured center frequency of BPF with a quality factor of 4.9 was deviated from 5.5 GHz to 4.7 GHz. The one with 14.8 was shifted to 5GHz. The theoretical and measured results validate that quality factor influences the center frequency shift of BPF.

Purpose: The purpose of this study is to analyze the trend of quality research by analyzing the entire JKSQM(Journal of the Korean Society for Quality Management). Methods: This study is to analyze the frequency of words used in the abstract of the all JKSQM by applying the text mining processing. We use wordcrowd among text mining techniques. Results: 22 words of high frequency were presented in the abstract of the paper published in the JKSQM for 42 years. The frequency of words was shown on a 10 year basis, and the four important words were plotted on a change graph for each Vol. Frequent words of each Vol. are added in the appendix. Conclusion: The main research results are as follows. First, there has been no significant change in research trends over the last 40 years. Second, the early SQC words have been widely used, and since 1990, many words such as service-oriented words have been used, indicating a change in the times. Third, the use of the words of the 4th industrial revolution since 2010 is weak. In the above analysis, the trend of quality research in Korea is within the quality category and can be considered conservative. Now, it is expected that everything will be changed in the period of the 4th Industrial Revolution, and it is time to study the direction of quality in Korea.

This experiment was carried out to investigate the effects of endophyte staWendophyte-free and -infect) and cutting frequency(3, 4, 5 and 6 timeslyear) on the forage quality of tall fescue(Festuca crnrtzdit~crcerr Schreb.) at the Experimental Field of Grassland and Forage Crops Division. National Livestock Research Institute, Suweon, from 1993 to 1994. 'Ihe results obtained are summarized as follows: CP content of tall fexue was increased with endophyte-free and cutting frequency for two varieties. Crude protein yield(CPY) of tall fescue in 1993 was increased with endophyte-free and cutting frequency for two varieties(P<0.05). In 1994, however. CPY of endophyte-free tall fescue was slightly lower than that of endophyte-infected tall fescue and the higher CPY was observed when tall fescue was harvested 6 times per year. NDF content of tall fescue was not different between endophyte-infected and -free. NDF was decreased with cutting frequency for two varieties in 1993, however. it was not influenced by the endophyte and cutting frequency in 1994. ADF content of tall fescue was not different between endophyte-infected and -free. and it was decreased with cutting frequency for two varieties. IVDMD was not influenced by endophyte, however, it was increased with cutting frequency for two varieties. Based on the results of this experiment, it is suggested that a slight increase in forage quality could be obtained from endophyte-free tall fescue and the quality was increased with frequent cutting.

In this paper, we present a cost effective parallel-branch spiral inductor with the enhanced quality factor and the resonance frequency. This structure is designed to improve the quality factor, but different from other fully stacked spiral inductors. The parallel-branch effect is increased by overlapping the first metal below the second metal with same direction. Measurement result shows an increased quality factor of 12 % improvement. Also, we show an octagonal parallel-branch inductor which reduces the parasitic capacitances for higher frequency applications.

Power system of Jeju is interconnected to the mainland using HVDC and that is also interconnected to three wind farms. It will be difficult to control of Jeju power system if HVDC is disconnected or HVDC is overhauled under large scale wind farms interconnected. We measured and analysed the power quality of two substation and two wind farms to assess that wind farms have an effect on Jeju system during the HVDC overhaul last May. We concentrated on the power quality like frequency, voltage variation, voltage harmonics, current harmonics, flicker. We can found that the frequency of Jeju system is very unstable during overhaul, so the frequency of Jeju system can be variated easily by wind farm's rapid output power variation. There are some benefits and weak points in power quality between two wind farms because each wind farm is consist of different wind turbines.
