Objectives: This study aimed to examine the frequency of convenience food consumption at convenience stores (CVS) and the CVS usage patterns of middle and high school students as well as to understand students’ attitude toward sodium and sugar reduction. Methods: We used an online questionnaire for data collection. The questionnaire comprised five distinct categories: general characteristics, CVS usage, frequency of consumption according to convenience food menus at CVS, attitude toward sodium and sugar reduction, and adherence to dietary guidelines. Results: A total of 75 students from Seoul (14 middle school students and 61 high school students) participated in the study. Most respondents visit CVS 3-5 times a week. CVS are predominantly used during weekdays, mostly during lunch, and dinner. The students mostly checked the caloric content and expiration date as food labeling information. The participants were aware of the need to reduce their sugar and sodium intake. Among frequent CVS convenience food consumers, there was an increased consideration of the need to reduce their sugar and sodium consumption, despite their actual selection of foods with high sugar and sodium content. Additionally, they did not check the sugar and sodium levels indicated in food labeling. Further, the dietary action guide from the Ministry of Health and Welfare were poorly followed by most students. Conclusions There is a need for nutrition education specifically addressing the sugar and sodium content of the convenience foods predominantly consumed by students. Additionally, educating students with frequent convenience food consumption to actively check the sugar and sodium information on food labels could help promote healthier food choices.

Purpose: The purpose of this study was to understand the meaning of gambling addiction from the perspective of problematic gamblers through their life stories. Methods: A narrative approach was utilized for this study. The data were collected from June 1 to September 30, 2019, from a purposive sample of three participants by using in-depth interviews, observations, and note-taking. Results: The participants told their life stories from childhood, stressing the experiences of being abused physically and emotionally by their own families. Their life stories commonly revealed that they became involved in gambling to escape the influence of the violence they had suffered. Due to their childhood abuse experiences, they had various problems, including distorted values toward money, low self-esteem, ambivalent feelings, and a lack of interpersonal coping skills, which often contributed to their addiction problems. Conclusion This study is meaningful in that it tried to understand the current addiction problem by focusing on the individual life experiences from the past to the present. Addiction recovery involves not only stopping the problematic behavior but also forming a new life meaning to lead a confident and independent future.

Purpose: The purpose of this study was to develop a theory on the gambling addiction process in adults who experienced domestic violence in childhood. Methods: Data were collected from 20 adults from May 1st to August 30th, 2020. Data were analyzed using grounded theory methodology as suggested by Strauss and Corbin. Results: The core category of this study was revealed to be ‘becoming addicted to gambling to avoid the physical and emotional pain caused by childhood domestic violence and be rewarded’. The core phenomenon was ‘struggle from pain’, which was derived from casual and contextual conditions: ‘ruthless physical violence’, ‘intolerable psychological pain’, and ‘bystand of violence’, ‘family addiction problem’. ‘parental immoral attitude’, The action and interaction strategies were ‘making money by any means’, and ‘gambling to forget the pain’. The intervening conditions affecting them were ‘a distorted view of money’, ‘resignation to helpless’, and ‘avoiding emotional distress’. The phases abbreviated through the produced process were the trauma phase, the avoidance phase, and the addiction phase. Conclusion Adults became addicted to gambling as a manifestation of distorted compensation mentality in an attempt to avoid the physical and emotional trauma of domestic violence in childhood.

Background: This retrospective study investigated the incidence rate of accidental foreign body aspiration and ingestion according to patient sex, age, and dental department. This study aimed to verify whether the incidence rate is higher in geriatric than in younger patients and whether it is different among dental departments. Methods: Accidental foreign body aspiration and ingestion cases were collected from electronic health records and the safety report system of Yonsei University Dental Hospital from January 2011 to December 2017. The collected data included patients’ age, sex, medical conditions, treatment procedures, and foreign objects that were accidentally aspirated or ingested. The incidence rate was calculated as the number of accidental foreign body aspirations and ingestions relative to the total number of patient visits. Differences depending on the patients’ sex, age, and dental department were statistically identified. Results: There were 2 aspiration and 37 ingestion cases during the 7-year analysis period. The male to female incidence ratio was 2.8:1. The incidence rate increased with age and increased rapidly among those aged 80 years or older. Seven of the 37 patients with accidental foreign body ingestion had intellectual disability, Lou Gehrig’s disease, dystonia, or oral and maxillofacial cancer. The incidence rate was highest in the Predoctoral Student Clinic and the Department of Prosthodontics. The most frequently swallowed objects were fixed dental prostheses and dental implant components. Conclusion The incidence rate of accidental foreign body aspiration and ingestion differed according to patient sex, age, and dental department. Dental practitioners must identify high-risk patients and apply various methods to prevent accidental foreign body aspiration and ingestion in dental clinics. Inexperienced practitioners should be particularly careful.

Objective: To compare postoperative positional changes in the mandibular proximal segment between the conventional orthognathic surgery (CS) and the surgery-first approach (SF) using intraoral vertical ramus osteotomy (IVRO) in patients with Class III malocclusion. Methods: Thirty-eight patients with skeletal Class III malocclusion who underwent bimaxillary surgery were divided into two groups according to the use of preoperative orthodontic treatment: CS group (n = 18) and SF group (n = 20). Skeletal changes in both groups were measured using computed tomography before (T0), 2 days after (T1), and 1 year after (T2) the surgery. Three-dimensional (3D) angular changes in the mandibular proximal segment, condylar position, and maxillomandibular landmarks were assessed. Results The mean amounts of mandibular setback and maxillary posterior impaction were similar in both groups. At T2, the posterior portion of the mandible moved upward in both groups. In the SF group, the anterior portion of the mandible moved upward by a mean distance of 0.9 ± 1.0 mm, which was statistically significant (p < 0.001). There were significant between-group differences in occlusal changes (p < 0.001) as well as in overjet and overbite.However, there were no significant between-group differences in proximal segment variables. Conclusions: Despite postoperative occlusal changes, positional changes in the mandibular proximal segment and the position of the condyles were similar between CS and SF, which suggested that SF using IVRO achieved satisfactory postoperative stability. If active physiotherapy is conducted, the proximal segment can be adapted in the physiological position regardless of the occlusal changes.

Obesity and type 2 diabetes mellitus are world-wide health problems, and lack of understanding of their linking mechanism is one reason for limited treatment options. We determined if genetic deletion of vimentin, a type 3 intermediate filament, affects obesity and type 2 diabetes mellitus.
