Results: Firstly, the articles on holiday stress have been increased, showing the rapid increase per year for the last 20 years. It is presumed to be closely related to the socio-economic situation. Second, although there have been 'married women' overwhelmingly as the subject of holiday stress, the frequency of the young generation has been increasing recently including the 'married women'. Third, the 96.7% of the contents from psychological appeal appeared in the case of holiday stress is related to family values. Especially, the holiday stress related to 'value of patriarchy' was the biggest stress. However, there has been increasing holiday stress caused by 'value of kinship' and 'value of marriage' recently. Forth, as a countermeasure against the holiday stress, the 'perception on the change of family values' has been quantitatively suggested and it has become actively appeared in terms of contents after mid-2000s. However, it has been appeared low in terms of quantity and content recently. Conclusions: This study has significance since it has been verified that the holiday stress started from 'married women' but it has been expanded to the young generation and it is related to the change and co-existence of family values of our society.

The purpose of this study is to investigate the ways in which cultural beliefs influence the lifestyles of the residents and environmental activities, especially decorations on the fronts during holiday seasons. The relationship between holiday displays and cultural values are investigated in the study. This research conducts a case study of two ethnic neighborhoods to understand cultural identification, attachments and environmental decoration. The neighborhoods were visited and their activities were observed during the holidays including Easter, Thanksgiving, Halloween and Christmas from 1992 to 1995. Exterior decorations were measured by a field survey of the frontal areas of 200 houses. This study confirms that the fronts are recognized and evaluated as cultural communications. The holiday decorations and celebrations are intimately related to cultural dimensions. Distinctive groups use different environmental elements in the celebration of holidays. Each culture is distinguished by its own rituals constituted by the interweaving of space and activities.

The purpose of this study is to demonstrate empirically whether replacement intervals of mobile phones sold in China online B2C are influenced by purchase points such as holidays. If there is a holiday effect, it is expected that the product replacement interval or interpurchase interval will be short compared to the usual one at holiday time. In order to verify this positively, at TMall, one of the largest B2C sites in China, we explored 5,132 replacement cycle intervals and the point of purchase at which one of the sales records of an agent dealing with all multinational mobile phones had minimum two purchase records. As a result, there was a buyer who had shorter replacement period than usual in holiday season. There was no statistically significant difference in the intervals of interchange between holidays. Based on the results, it was found that the mobile phone vendors were aware that purchasing was occurring due to the holiday.

Objectives: To identify post-treatment prognostic factors for medication-related osteonecrosis of the jaw (MRONJ). Materials and Methods: We evaluated 54 MRONJ patients who visited the Department of Dentistry, Ajou University Hospital, from May 2007 to March 2014. Twenty-one patients were surgically managed with debridement or sequestrectomy and 33 patients were conservatively managed using antibiotics. Correlations of age, sex, stage, bisphosphonate duration and type, and drug holiday with the prognosis of MRONJ were investigated. Correlations were verified by logistic regression analysis and t-tests with a significance level of 0.05. Results: Clinical outcomes were evaluated on the basis of both clinical and radiographic findings. Twelve out of 21 surgically managed patients showed a favorable prognosis and nine patients relapsed. Thirty-one of the 33 conservatively managed patients showed no specific change in prognosis, and two patients worsened. Statistical analyses of the conservative management group did not reveal any correlation of the above factors with the prognosis of conservative management. Drug holiday was the only prognostic factor in the surgical management group (P=0.031 in logistic regression analysis, P=0.004 in t-test). Conclusion: Drug holiday is a prognostic factor in the surgical management of MRONJ. Because the drug holiday in the patients of the poor prognosis group occurred 1.5 to 4 months prior to surgical management, we recommend a drug holiday more than 4 months before surgery.

Objectives: The present study was conducted to investigate associations between eating style and food intake of 45 female college students during Chuseok holidays. Methods: A ten-day food record was obtained and divided into two parts. The first five days (September 20-24, 2015) were considered as a 'Normal Day (ND 1-5)' and the subsequent five days (September 25-29) as 'Holiday (HD6-10)'. The middle three days (September 26-28) of the holidays were considered as the 'Peak Holiday (PD7- 9)'. Eating behaviors were measured using the Dutch Eating Behavior Questionnaire (DEBQ) and anthropometry was assessed in all study participants. Participants were grouped by cluster analysis according to the mean energy intake of the first three days of the Holiday. Results: Participants had a low-normal range of BMI and they were carefully restricting their food intake at Normal Day. Even the food intake did not exceed 2000 kcal per day during the Peak Holiday. External eating was the most prevalent type of eating behavior, followed by restrained eating and emotional eating. Normal energy and fat intake were correlated with the external eating subscale of the DEBQ. Restrained eating was associated with the weight, BMI, fat mass, waist, and hip girth of the subjects. Compared to the Normal Day, they overate during the Holiday with different eating styles including 'restraint', 'disinhibition', and 'fluctuation'. Therefore, neither eating behaviors nor anthropometry was associated with food intake during the Holiday. Although eating behaviors and anthropometric measures were not different among eating style clusters, the food intakes of disinhibition cluster were higher than those of restraint cluster during all the study periods. Conclusions: Subjects can be classified with the restraint, disinhibition, and fluctuation clusters. However, eating behaviors and anthropometry were not different among three clusters.

Objectives: Drug holidays are suggested to reduce the formation of osteonecrosis in patients under intravenous (IV) bisphosphonates (BPs) therapy. The objectives of this study are to evaluate the incidence of medication-related osteonecrosis of the jaw (MRONJ) following tooth extraction in cancer patients using IV BP, and to assess the effect of drug holiday on the development of MRONJ. Patients and Methods: A manuel search of the patient folders of Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Hacettepe University was undertaken to identify cancer patients who used IV BPs and had at least one tooth extraction between 2012 and 2022. Patents' age, sex, systemic condition, the type of BP used, duration of BP used, number of tooth extraction, duration of drug holiday, localization of tooth extraction and incidence of MRONJ were recorded. Results: One hundred nine teeth were removed from 57 jaws in 51 patients. All tooth extractions were performed under perioperative antibiotic prophylaxis and with primary wound closure. The incidence of MRONJ was 5.3%. Stage 1 MRONJ developed in 3 patients (only one had a drug holiday). The median duration of drug holiday was 2 months. No significant difference between the patients with and without a drug holiday and MRONJ development was found (P=0.315). The mean age of patients developed MRONJ was 40.33±8.08 years. A statistically significant difference was found between age and MRONJ development (P=0.002). Conclusion: The effect of a short-term drug holiday on the development of MRONJ may be limited because BPs remain in bone tissue for a long time. Drug holidays should be applied with the approval of an oncologist with other preventive measurements.
