The present study was conducted to assess the effect of freezing treatment of spring greens, herbs cultivated in spring (so called ‘bomnamul in Korean), on antioxidant activities and antigenotoxic activities. The antioxidant activities of ethanol extracts of nine spring greens (bud of aralia elater: BA, butterbur: BB, fragrant edible wild aster: FA, japanese hogfennel: JH, mugwort: MW, sedum: SE, shepherd spurse: SS, veronicastrum sibiricum: VS, wild garlic: WG) were investigated by 2,2-diphenyl-1-picryl hydrazyl (DPPH) radical scavenging activity and oxygen radical absorbance capacity (ORAC) assay. The total phenolic contents of seven spring greens extracts except JH and WG increased significantly by freezing treatment (24.7∼342.5%). Freezing significantly increased the DPPH radical-scavenging activity of BB, SE, SS and ORAC value of BA, FA, MW, VS and WG at 50 μg/ml. The CAC of SS and WG against AAPH- induced oxidative stress in HepG2 cells were significantly increased after freezing. The antigenotoxic effect of ethanol extracts of nine spring greens on DNA damage was evaluated by comet assay. The antigenotoxic effect of JH was significantly increased after freezing. It is widely believed that natural antioxidants found in common vegetables and herbs lost its activities during frozen storage. However, our study demonstrated that frozen spring greens ethanol extracts may retain or increase their antioxidant activity.

This study aims to comprehensively explore and compare pet-inclusive tourism and hotel experiences in South Korea and the United Kingdom from an anthrozoological perspective. The detailed objectives are as follows. First, it examines and contrasts the perception of pets as family members in both societies. Second, the study conducts comparative analyses of preparations for and experiences during pet-accompanied travel and hotel stays, investigating how these differences manifest. Third, it explores the influence of each culture's socio-cultural and institutional frameworks on pet-inclusive tourism and accommodations. The study employs a micro-ethnographic-based qualitative methodology, combining observational techniques with individual in-depth interviews. Pet-friendly hotels, restaurants, and museums in Gangneung, South Korea, and Cornwall, UK, were chosen for observation. After this, individual in-depth interviews were individually conducted with 22 adults who have pets and have experienced domestic travel involving overnight stays. The data, which was analyzed using thematic analysis, revealed four themes: ‘pets’ roles as family members’, ‘travel focus: pets vs. owners’, ‘determinants of travel satisfaction: pets vs. owners’, and ‘diverse attitudes towards pet-related policies.’ A key finding is that in South Korea, ensuring the comfort and pleasure of pets constitutes the primary objective of travel, which frequently leads to the selection of pet-friendly destinations and accommodations. Conversely, in the UK, travel plans predominantly revolve around the preferences and interests of the pet owners. These variations are shaped by each country's cultural backdrop, values, and policies and regulations concerning pets. The results of this study provide substantial foundational data for enhancing pet-accompanied travel services from a global perspective, illustrating its potential to augment satisfaction in pet-inclusive travel and foster growth in related industries.

This study examines the impact of virtual influencers, acting as service ambassadors, on the trustworthiness of digital tourism content based on construal-level theory. Specific objectives are as follows: (1) to investigate perceived competency differences in digital tourism content among Generation Z tourists as influenced by virtual influencers (hyper-realistic vs. animated), (2) to validate the interaction effects of virtual influencers(hyper-realistic vs. animated) and construal level(high vs. low) on the perceived competency of generation Z tourists and consequently on the trustworthiness of digital tourism content. (3) to examine the mediating effect of perceived competency on the relationship between virtual influencers and the trustworthiness of digital tourism content. This study employed a 2 (virtual influencer: hyper-realistic vs. animated) × 2 (construal level: high vs. low) between-group experimental design. Data were collected in January 2023 from 350 Generation Z European tourists via an online platform. The findings reveal that hyper-realistic virtual influencers elicited higher perceived competency in digital tourism content among Generation Z tourists than their animated virtual influencers. Notably, hyper-realistic virtual influencers exerted a greater influence when paired with low-level construal than high-level construal. Conversely, animated virtual influencers demonstrated a stronger impact when combined with high-level construal than low-level construal. Finally, perceived competency acted as a mediator in the relationship between virtual influencers and the trustworthiness of digital tourism content. This research enriches our understanding of how the format of virtual influencers influences Generation Z tourists’ perceived competency and trust in digital tourism content.

최미주,유승현,김금래,배유미,안선희,김성신,민성아,최진선,이승은,문여진,이은정,박철영,이원영,오기원,박성우,김선우 대한당뇨병학회 2011 Diabetes and Metabolism Journal Vol.35 No.6

Background: Diabetes self-management education and reinforcement are important for effective management of the disease. We investigated the effectiveness of interactive small-group education on glycemic, blood pressure, and lipid levels. Methods: For this study, 207 type 2 diabetes patients with suboptimal glycemic control (HbA1c levels >6.5%) were enrolled. The conventional education group received an existing education program from April to November in 2006, and the interactive education group received a new small-group education program from December 2006 to July 2007. The two groups were comparatively analyzed for changes in blood sugar, glycated hemoglobin, lipid, and blood pressure at baseline, 3, 6, and 12 months and the proportion of patients achieving target goals at 12 months. Results: After 12 months of follow-up, HbA1c levels in the interactive education group were significantly lower than in the conventional education group (6.7% vs. 6.4%, P<0.001). Fasting and 2 hour postprandial glucose concentrations, total cholesterol, and low density lipoprotein cholesterol were significantly lower in the interactive education group than in the conventional education group. The proportion of patients that achieved target goals was significantly higher in the interactive education group. Conclusion: The small-group educational method improved and re-established the existing group educational method. This finding suggests that the importance of education appears to be related to the method by which it is received rather than the education itself. Thus, the use of small-group educational methods to supplement existing educational methods established for diverse age levels should be considered in the future.

최미주 ( Choi Mi Joo ),이영애 ( Lee Young Ae ) 한국놀이치료학회 2017 한국놀이치료학회지(놀이치료연구) Vol.20 No.2

본 연구에서는 아동이 지각한 부모의 자율-통제 양육태도가 심리적 안녕감에 미치는 영향에서 스트레스 대처행동의 매개효과를 규명하였다. 이를 위해 경기도 및 경상도에 위치한 초등학교 5, 6학년 489명을 대상으로 아동용 부모 양육태도 척도, 스트레스 대처행동 척도, 심리적 안녕감 척도를 사용하였다. 수집된 자료는 SPSS 22.0을 사용하여 분석하였다. 각 변인의 관계를 확인하기 위해 상관분석과 중다회귀분석을 실시하였으며, 아동이 지각한 부와 모의 자율-통제 양육태도와 심리적 안녕감의 관계에서 스트레스 대처행동의 매개효과를 검증하기 위해 Baron과 Kenny(1986)가 제안한 매개효과 검증 절차를 사용하였다. 또한 Sobel의 검정방식으로 매개효과의 통계적 유의성을 검증하였다. 본 연구결과를 요약하면 다음과 같다. 첫째, 아동의 지각된 부·모의 자율-통제 양육태도 총점은 심리적 안녕감 총점과 유의한 정적 상관관계를 나타났다. 지각된 부의 자율-통제 양육태도 총점은 스트레스 대처행동의 하위요인(적극적, 공격적)과 유의한 상관관계가 나타났다. 지각된 모의 자율-통제 양육태도 총점은 스트레스 대처행동의 하위요인(적극적, 공격적, 사회지지 추구적)과 유의한 상관관계가 나타났다. 또한, 스트레스 대처행동의 각 하위요인들은 심리적 안녕감과 유의한 상관관계가 나타났다. 둘째, 부모의 자율-통제 양육태도와 심리적 안녕감의 관계에서 스트레스 대처행동의 매개효과를 검증한 결과, 아동이 지각한 부의 자율-통제적 양육태도는 스트레스 대처행동(적극적, 공격적)을 부분매개로 하여 아동의 심리적 안녕감을 유의하게 설명하는 것으로 나타났다. 또한 아동이 지각한 모의 자율-통제적 양육태도는 스트레스 대처행동(적극적, 공격적, 사회지지 추구적)을 부분매개로 하여 아동의 심리적 안녕감을 유의하게 설명하는 것으로 나타났다. 이와 같이 본 연구를 통하여 아동이 지각한 부와 모의 양육태도가 스트레스 대처행동에 미치는 영향력에 차이가 있다는 점을 규명하였고, 심리치료에서 아동의 심리적 안녕감을 증진시키기 위해서는 스트레스 대처행동과 같은 내적변인을 다루는 것의 중요함을 확인하였다. This study examined the meditating effects of stress-coping behavior on the relationship between the paternal and maternal autonomic-control attitude and children`s psychological well-being. Survey data from 489 children in the 5th and 6th grades in elementary schools were harvested for analysis. To examine possible mediating effects, Baron and Kenny`s(1986) model was applied together with the SPSS 22.0. Sobel`s(1982) test was used to verify the significance of the mediation effects. The study revealed the following results. First, perceived parent`s autonomic-control attitude showed a significantly positive correlation to that of psychological well-being. Perceived paternal autonomic-control attitude showed a significantly correlation with stress-coping behaviors (active, aggressive), and perceived maternal autonomic-control attitude showed a significantly correlation to the stress-coping behaviors (active, aggressive, social support). Stress coping behaviors showed a significant correlation to psychological well-being. Second, the children`s stress coping behaviors(active, aggressive) exerted a partial mediating role on the perceived paternal autonomic-control attitude and psychological well-being, and children`s stress coping behaviors (active, aggressive, social support) had a partial mediating role on the perceived maternal autonomic-control attitude and psychological well-being. This study confirmed the difference of paternal and maternal influences on stress-coping behavior, and the importance of internal variables such as stress-coping behaviors, in order to improve children`s psychological well-being in psychotherapy.
