Value Engineering(VE) is an organized effort to create the most value through a functional analysis and creation of alternatives. Depending on the VE job plan, a VE Workshop must be performed in a certain place within a certain period of time. A VE Workshop, which is an organized activity that aims to create the best value through functional analysis and creation of alternatives, should be held in a certain place and at a scheduled time according to the VE job plan. In the Pre-Study, VE Study and Post-Study phases of VE, functional assessments, performance evaluations and idea evaluations are driven by variable management techniques and analysis methods, respectively. Generally, VE is executed for about 3 to 5 days in a particular place to create value. However, there are many problems associated with limiting all VE processes to a specific place and schedule. Moreover, in Korea, VE teams are required to finish all VE processes in a limited time because of the short duration of VE workshops, the necessity of which has been overlooked. Therefore, an efficient VE support system is required to resolve the problem of time and space limitations. In this study, a VE support system based on the Mobile environment was developed to support the VE Workshop process. This VE support system enables participants to review design documents, drawing sheets and all VE-related documents using mobile devices. After the Workshop, participants can conveniently rearrange the result(evaluation of function and ideas) at the workshop. Not only can the members of VE team can review the design documents, drawing sheet and all VE-related documents in the step before the workshop, but also the result(evaluation of function and ideas) of the workshop can be easily rearranged in the phase after the workshop under the developed supporting system using mobile devices.

The purpose of this study is to elucidate the impact of authenticity on experience value and subjective well-being among visitors who have participated in direct experiential activities in experiential fishing villages. The research method used literature research methods and empirical research methods using questionnaires, and this questionnaire was composed by determining three major variables and seven constituent factors for each variable through factor analysis and conducting prior research and preliminary surveys. The survey was conducted from February 5, 2023 to April 5, 2023 among experimental fishing villages with excellent ratings for scenery (environment), service, experience, accommodation, and food, and four villages that can experience tidal flats and manage customers online. The survey was conducted from February 5, 2023 to April 5, 2023, among experimental fishing villages with excellent ratings for scenery (environment), service, experience, accommodation, and food, and four villages that can experience tidal flats and manage customers online. The results of this study are as follows. First, the factors of authenticity in experiential fishing villages include three sub-factors: objective authenticity, constructive authenticity, and existential authenticity. The factors of experience value include two sub-factors: emotional values and functional values. Subjective well-being is derived from positive emotion and life satisfaction. Second, upon examining the importance of authenticity in experiential fishing villages, it was found that existential authenticity and objective authenticity, in that order, have a significant impact on emotional values. However, constructive authenticity did not have a significant impact on emotional values. Third, in terms of functional values, constructive authenticity, existential authenticity, and objective authenticity, in that order, had a significant impact. Fourth, experience value, in the order of emotional values and functional values, had a significant impact on positive emotion and life satisfaction of subjective well-being. Therefore, it was confirmed that the authenticity of experiential fishing villages is important as a strategy to enhance experience value and subjective well-being. Especially, considering that the majority of visitors to experiential fishing villages are family-centered (86.5%), applying marketing management strategies to develop programs that enhance existential authenticity and improve emotional values could elevate the subjective well-being of experiential visitors.

Rice ageing describes the changes in physical and chemical properties of rice grains during storage that alter the eating quality of rice. The prevention of deterioration in palatability of rice during storage is important for stable supply. In this study, We conducted to select the variety with superior palatability after storage at room temperature. 'Yeonghojinmi' had much higher head rice ratio of milled rice than that of 'Ilmi', 'Junam'and 'Hwayeong'at similar moisture content of approximately 15%. Grossiness and stickiness were higher in 'Yeonghojinmi' than that of the others. Meanwhile, yellowness(b value) of cooked rice was lower in 'Yeonghojinmi' than that of the others. Of the four varieties, Yeonghojinmi was maintained good eating quality after storage in room temperature, which also contributed to differences in palatability, such as protein content, glossiness, stickiness and color of cooked rice.

This study was carried out to compare the physicochemical characteristics of Korean traditional wine fermented from proso millet and nuruk at different mixing rate. The alcohol contents of the fermented wine ranged from 12.36 to 13.21%. Two kinds of nuruk, SH and BS nuruks were used. The brix degrees of proso millet wine fermented by SH and BS nuruks were 21.6 and 22.4 $^{\circ}Bx$, respectively. The pH, total acidity, and turbidity the wines fermented by SH and BS nuruks were 3.74 and 3.40, 1.40 and 1.51%, and 0.441 and 0.149, respectively. With increasing the addition amount of proso millet, brix degree, pH, turbidity L-value decreased, and total acidity and avalue increased. Total color difference (${\Delta}Eab$) parameter of the wine fermented by SH nuruk were 4.33, 6.63 and 26.13, and by BS nuruk were 4.08, 5.29 and 10.59 in 30, 70 and 100% addition rates of proso millet. With increasing the addition amount of proso millet, glucose content decreased. The organic acids such as lactic acid and acetic acid were predominantly detected in the fermented wine. Finally, based on sensory evaluations, the wine fermented by SH nuruk showed the best overall quality at 30% addition rate of proso millet.

Purpose: To evaluate the correlation between colon transit time (CTT) test value and initial maintenance dose of polyethylene glycol (PEG) 4000 or lactulose. Methods: Of 415 children with chronic functional constipation, 190 were enrolled based on exclusion criteria using the CTT test, defecation diary, and clinical chart. The CTT test was performed with prior disimpaction. The laxative dose for maintenance was determined on the basis of the defecation diary and clinical chart. The Shapiro-Wilk test and Pearson's and Spearman's correlations were used for statistical analysis. Results: The overall group median value and interquartile range of the CTT test was 43.8 (31.8) hours. The average PEG 4000 dose for maintenance in the overall group was $0.68{\pm}0.18g/kg/d$; according to age, the dose was $0.73{\pm}0.16g/kg/d$ (<8 years), $0.53{\pm}0.12g/kg/d$ (8 to <12 years), and $0.36{\pm}0.05g/kg/d$ (12 to 15 years). The dose of lactulose was $1.99{\pm}0.43mL/kg/d$ (<8 years) or $1.26{\pm}0.25mL/kg/d$ (8 to <12 years). There was no significant correlation between CTT test value and initial dose of laxative, irrespective of the subgroup (encopresis, abnormal CTT test subtype) for either laxative. Even in the largest group (overall, n=109, younger than 8 years and on PEG 4000), the correlation was weak (Pearson's correlation coefficient [R]=0.268, p=0.005). Within the abnormal transit group, subgroup (n=73, younger than 8 years and on PEG 4000) correlation was weak (R=0.267, p=0.022). Conclusion: CTT test value cannot predict the initial maintenance dose of PEG 4000 or lactulose with linear correlation.

Objectives: The aim of this study was to develop a Phlegm Pattern Questionnaire for Functional Dyspepsia (PPQ-FD) by modifying a previously developed Phlegm Pattern Questionnaire (PPQ) and to verify its reliability and validity. Further objectives were to obtain the optimal cut-off value for the PPQ-FD for standardization and for clinical use. Methods: The PPQ-FD was developed by extracting the major symptoms of the phlegm pattern in functional dyspepsia and by using the Delphi method to administer a requested importance survey to experts. The reliability, validity, and optimal cut-off value of the PPQ-FD were analyzed by enrolling a total of 60 subjects in this study. Thirty patients were diagnosed with both functional dyspepsia and phlegm pattern and thirty patients were diagnosed with only functional dyspepsia. All participants were requested to fill out the PPQ-FD. Results: No statistically significant differences were detected in the two groups for sex distribution, age, or body mass index. Five of the survey questions negatively affected its reliability; therefore, we decided to exclude those five questions on further inspection. The Cronbach's α coefficient of the revised PPQ-FD was 0.853, and clinical validity was verified. Construct validity was analyzed by factor analysis and identified four factors. Statistically significant positive correlations were found between the revised PPQ-FD and other dyspepsia scales, such as the SQDQ, SSQD, VAS, NDI-K, and FD-QoL scales. The VAS had particularly strong positive correlations with the PPQ-FD. Conclusions: The PPQ-FD developed in this study has fundamental reliability and validity for use as a pattern-diagnosis questionnaire. The PPQ-FD can help to diagnose the phlegm pattern in patients with functional dyspepsia.

Objectives: Several pattern diagnosis questionnaires have been developed to objectify the process of pattern diagnosis in Korean medicine. In this context, this study aimed to develop a food retention questionnaire for functional dyspepsia (FRQ-FD) by modifying the previously developed food retention questionnaire (FRQ) and to verify its reliability and validity. Furthermore, this study aimed to identify the optimal cut-off value of the FRQ-FD for standardization and use in clinical situations. Methods: To develop the FRQ-FD, we extracted the major symptoms of food retention pattern for functional dyspepsia from Chinese/Korean medicine textbooks and requested an importance survey from experts using the Delphi method. The first draft of the FRQ-FD was composed of 25 questions comprising 8 questions from the textbooks and the Delphi method and 17 questions from the FRQ already developed in 2013. To analyze its reliability, validity, and optimal cut-off value, 60 subjects were enrolled in this study from June 25 to August 13, 2018. Thirty patients were diagnosed as both functional dyspepsia and food retention pattern, and 30 healthy participants were not. All participants were requested to fill up the FRQ-FD, Stomach Qi Deficiency Questionnaire (SQDQ), Scale for Stomach Qi Deficiency pattern (SSQD), visual analog scale (VAS) for dyspepsia, Nepean Dyspepsia Index-Korean version (NDI-K), and functional dyspepsia-related quality of life (FD-QoL). Results: No statistically significant differences were found in sex distribution, age, and body mass index between the patient group and the control group. As five questions affected the reliability negatively and three questions affected the clinical validity negatively, we decided to exclude the eight questions upon further investigation. The Cronbach's ${\alpha}$ coefficient of the revised FRQ-FD (17 items) was 0.899, and its clinical validity was verified. Construct validity was analyzed by factor analysis and produced five factors. Statistically significant positive correlations were found between the revised FRQ-FD and the other dyspepsia scales, namely, SQDQ, SSQD, VAS, NDI-K, and FD-QoL. VAS and NDI-K especially had strong positive correlations with FRQ-FD. Conclusions: The FRQ-FD developed in this study can provide fundamental reliability and validity for a pattern diagnosis questionnaire. FRQ-FD can help to diagnose food retention pattern in functional dyspepsia patients. Further studies are required to inspect several statistical factors.
