Purpose: This study aimed to develop a motivational interviewing pulmonary rehabilitation program based on self-determination theory to maintain pulmonary rehabilitation-related health behaviors in patients with chronic obstructive pulmonary disease. The program was developed by reviewing the literature on pulmonary rehabilitation guidelines, drawing on the self-determinism theory to establish its contents, recruiting experts to test its validity, and conducting a preliminary survey. Methods: A quasi-experimental design was used to confirm the effect of the program. The participants were outpatients diagnosed with chronic obstructive pulmonary disease at three general hospitals in Busan. There were 33 subjects: 15 in the experimental group and 18 in the control group. The experimental group performed a motivational interviewing pulmonary rehabilitation program which comprised 11 sessions delivered over 10 weeks. The outcomes were measured using basic psychological needs, dyspnea, 6-minute walking distance, and functional status. Intervention effects were analyzed using repeated-measures ANOVA. Results: The analysis revealed significant differences between the experimental and control groups in competence among the subdomains of basic psychological needs, dyspnea during exercise, and functional status. Conclusion: The developed program affects physical conditions and can be applied as an effective clinical nursing intervention to continuously improve the pulmonary rehabilitation behavior of patients with chronic obstructive pulmonary disease.

In this study, STS316L produced by a double-melting process involving vacuum induction melting (VIM) and vacuum arc remelting (VAR) was subjected to extrusion and drawing to form a tube and was subsequently electrolytic polished (EP). The grain size of the obtained STS316L without EP was approximately 55 ㎛, with no difference found after EP. The thickness of the EP layer was measured by AES and TEM, showing values of approximately 10 nm and 15 nm, respectively. After EP, the Cr/Fe and CrO/FeO ratios of the passive layer increased from 1.48 to 1.62 and from 2.15 to 2.26, respectively, while the surface roughness decreased significantly from 0.255 to 0.024 ㎛. Consequently, the corrosion rate decreased in both NaCl and HCl solutions after the EP process. Additionally, the amounts of eluted Cr and Fe ions were reduced from 1.2 to 0.8 ppb and 10.3 to 0.8 ppb, respectively. Furthermore, polarization tests revealed that STS316L treated with EP required a lower current density to reach a passive state, indicating that corrosion behavior was retarded.

Purpose: Although many studies have addressed destination marketing concepts, the relationship between beach tourists' memorable tourism experience (MTE), revisit intention and electronic word of mouth (eWOM) remains unknown. To address this issue, the authors established a model to investigate the effects of MTE's dimensions on revisit intention and eWOM. Research design, data and methodology: Drawing on 581 questionnaires from domestic beach tourists in Vietnam, a quantitative study approach was administered to empirically analyze a partial least squares path model in PLS-SEM. Results: The findings revealed that four dimensions of MTE including hedonism, local culture, meaningfulness and involvement have positive influence on beach tourists' revisit intention. Besides, meaningfulness and knowledge directly affect eWOM. It is worth noting that beach tourists' revisit intention significantly and directly influence their eWOM. The findings also confirm the indirect effects of hedonism, local culture, meaningfulness and involvement on eWOM through the mediating role of revisit intention. Conclusions: This study will be important to determine beach tourists' behavior through each dimension of MTE. This study also emphasizes on the direct effect of beach tourists' revisit intention on eWOM, as well as confirms its mediating role in the relation between MTE and eWOM. The findings will assist policymakers and destination marketers with strategies and effective future actions.

Purpose: This study aimed to examine the influence of private label cues, including store image, product design, price promotion, and origin image, on consumers repurchase intention by mediating consumption value from a distribution perspective. Additionally, it explored nationality's moderating role in the relationship between consumption value and repurchase intention. Research design, data and methodology: Drawing on the SOR model, data were collected from 246 consumers who had purchased private-label products in the past month. Structural equation modeling analysis was employed to test hypotheses using AMOS and SPSS. Results: Findings revealed that cues significantly impact consumers' perception of consumption value, influencing repurchase intention. Price promotion directly affected repurchase intention, while other cues indirectly influenced it through consumption value mediation. Nationality moderated the relationship between consumption value and repurchase intention, with Korean consumers showing a higher propensity to repurchase than Chinese consumers. Conclusions: Theoretical implications of the study contributed to understanding consumer behavior by confirming the impact of private label cues, elucidating their differential effects on repurchase intention, and integrating theoretical frameworks. Managerial implications underscored the significance of leveraging cues to enhance consumption value perceptions, tailoring marketing strategies to accommodate cultural nuances, and utilizing cues to bolster consumer repurchase intentions, ultimately enhancing distribution channel effectiveness.

본 연구에서는 기존연구들이 OCB의 선행요인들에 대한 지속적인 연구를 해 오고 있음에도, 환원주의적 회귀모형 혹은 이변량적 접근에 치중함으로써, 그 수행동기를 충분히 설명해 내지는 못하고 있다는 비판에 착안하고 있다. OCB는 본질적으로 지극히 주관적이고, 가변적인 속성을 띠기에, 구성원들이 자신의 관점과 입장에서 OCB를 어떻게 인식 및 해석하고 또 수행하는 지를 탐구할 필요가 제기되는 바, 그 속성상 이에 매우 부합하는 특성을 지닌 Q방법론을 적용하며, 두 가지 연구과제, 즉, 첫째, OCB의 수행동기에 대한 구성원들의 인식유형을 파악하고, 둘째, 파악된 인식유형별로 그 구체적 특성을 비교분석한다. 17명의 P표본을 대상으로 분석한 결과 모두 4가지 유형의 OCB수행의 주관적 동기가 도출되고 있는 바, 각기 그 특징에 부합하도록 규범기반형, 수단기반형, 기질기반형, 그리고 회피기반형이라는 명칭들을 부여하였다. 이 유형들은 대부분 기존연구들에서 이론적으로 논의되어 왔던 OCB의 수행동기들에 부합하는 특징 들을 드러냄과 동시에, 서로 분명하게 구분되는 차별성을 보여주고 있어 매우 흥미롭다. 한편 본 연구에서 회피기반형이라 명명된 마지막 유형의 경우에는 기존의 연구들에서는 전혀 논의된 바 없는 OCB의 새로운 수행동기유형으로서, 차후 집중적인 연구가 필요한 부분이라 할 것인데, 이는 가설생성적인 Q방법론의 특징을 여실히 보여주고 있다할 것이다.

Wet-spun silk fibers have attracted the attention of many researchers because of 1) the unique properties of silk as a biomaterial, including good biocompatibility and cyto-compatability and 2) the various methods available to control the structure and properties of the fiber. Cellulose nanofibrils (CNFs) have typically been used as a reinforcing material for natural and synthetic polymers. In this study, CNF-embedded silk fibroin (SF) nanocomposite fibers were prepared for the first time. The effects of CNF content on the rheology of the dope solution and the characteristics of wet-spun CNF/SF composite fibers were also examined. A 5% SF formic acid solution that contained no CNFs showed nearly Newtonian fluid behavior, with slight shear thinning. However, after the addition of 1% CNFs, the viscosity of the dope solution increased significantly, and apparent shear thinning was observed. The maximum draw ratio of the CNF/SF composite fibers decreased as the CNF content increased. Interestingly, the crystallinity index for the silk in the CNF/SF fibers was sequentially reduced as the CNF content was increased. This phenomenon may be due to the fact that the CNFs prevent ${\beta}$-sheet crystallization of the SF by elimination of formic acid from the dope solution during the coagulation process. The CNF/SF composite fibers displayed a relatively smooth surface with stripes, at low magnification (${\times}500$). However, a rugged nanoscale surface was observed at high magnification (${\times}10,000$), and the surface roughness increased with the CNF content.

This study was performed to develop dietary education programs for children, by researching the actual conditions of dietary education and its demand aimed at teachers in child centers in Masan. Most of the interviewed teachers were in their 20s(71%) with under 5 years teaching experiences(56.8%), and working in a kindergarten environment(34.9%). The rate of doing dietary education on mealtime was 96.4%. The main items taught pertained to 'not leaving food(20.6%)' and 'washing hands before meals(20.5%)'. The primary teaching method for students with unbalanced eating habits was 'eating after teaching them to understood(76.8%). The primary reward for good behavior was 'using food(76.8%)', usually as 'candy'(50.8%) or 'cookies'(25.8%). The desirable dietary education type was 'during spare moments(52.6%)' and 'at mealtime (23.5%)'. The concepts taught were 'balanced eating(23.2%)' and 'food hygiene(21.2%), and the students were interested in 'the roles of foods and nutrients'(34.5%), 'balanced eating(20.9%)', and 'food hygiene(19.1%)'. Educational activities encompassed 'pictures and drawing(25.7%)', 'fairy tales(23.4%)', 'songs(19.4%)', and 'play(14.1%)'. Also, the activities of most interest were 'fairy tales(29.4%)', 'play(24.4%)', and then 'songs(23.1%)'. The greatest difficulties during dietary education were 'attracting interest from the children(37.8%)' and 'making and purchasing materials(33.9%)'. Approximately, 44.2% of the teachers had experiences in dietary education, and 96.4% stated teachers had the intention to participate in dietary education. They want to address 'child meal direction(23.0%)', 'health problems(22.7%)', and then 'child nutrient requirements (17.3%)'. Also the majority wanted it two times per year(57.6%) or one time per year(30.9%). This study indicated that proper dietary education must be established in child centers by developing various practical dietary education programs and then implementing them.
