In this study, we investigated the effects of perceived health and ageism experience of the elderly on successful aging, which were respectively presumed as predictors of biomedical model and psychosocial model of the successful aging. As important research results, firstly, negligence among ageism experience constructs appeared higher than other discriminatory experiences. Secondly, male showed significantly higher discriminatory experience than female in the area of 3 constructs such as property, negligence and employment ageism. Also there were some different discriminative experiences in the area of perceived health and ageism in terms of age, wealth and education. Finally, the results of hierarchical multiple regression hired to find out factors influencing successful aging showed that the factors such as sex, wealth, perceived health and property discrimination of ageism affected successful ageing. Based on the analytic results, we verified that perceived health, i.e., predictor of biomedical model had higher effect on successful aging than ageism experience, i.e., predictor of psychosocial model of successful aging. Thus, it was suggested that health promotion policy should be considered with priority and also combating ageism as well for successful aging.

Background: Hapcheon-gun, Gyeongsangnam-do, is designated as an emergency medical vulnerable area, facing significant challenges in transporting and treating emergency patients. A detailed analysis of the regional emergency medical system is required to identify effective solutions. Methods: This study employed a mixed-methods approach, combining quantitative data from the National Emergency Medical Information System and emergency activity logs with qualitative data from focus group interviews involving 24 stakeholders, including medical staff, paramedics, civil servants, and local residents. Results: Quantitative findings indicated an aging population in Hapcheon-gun, with a growing number of elderly emergency room users. Despite the utilization of local emergency medical institutions, a lack of trust and preference for urban hospitals led even patients with mild conditions to seek care at higher-level facilities. Following the COVID-19 pandemic, transport distances and times for patients using 119 emergency services increased. Qualitative analysis identified several issues: limited capacity of local institutions, challenges in patient transport due to misaligned emergency medical zones, an increase in severely ill patients, and the absence of a coordinated emergency medical consultative body. Recommendations include strengthening local institutions through government support, realignment of emergency zones, legal reforms, the establishment of a continuous consultative body, and enhancing the capacity of medical staff, paramedics, and residents. Conclusion: Improving the emergency medical system in Hapcheon-gun will require targeted efforts in institutional strengthening, legal and administrative support, and capacity-building initiatives.

Glandular odontogenic cyst (GOC) is a rare, potentially aggressive jaw lesion. The common radiographic features include a well-defined radiolucency with distinct borders, presenting a uni- or multilocular appearance. A cystic lesion in the posterior mandible of a 78-year-old female was incidentally found. Radiographs showed a unilocular lesion with a scalloped margin, external root resorption of the adjacent tooth, and cortical perforation. This lesion had changed from a small ovoid shape to a more expanded lesion in a period of four years. The small lesion showed unilocularity with a smooth margin and a well-defined border, but the expanded lesion produced cortical perforation and a lobulated margin. The provisional diagnosis was an ameloblastoma, whereas the histopathological examination revealed a GOC. This was a quite rare case, given that this radiographic change was observed in the posterior mandible of an elderly female. This case showed that a GOC can grow even in people in their seventies, changing from the unilocular form to an expanded, lobulated lesion. Here, we report a case of GOC with characteristic radiographic features.

Since most of the urban railway operating agencies are established and operated by local governments, Public Service Obligation(PSO) is given priority. Therefore, free riding is carried out based on individual laws and regulations. In Korea, as the aging population goes, the increase in the number of elderly passengers on the urban railways is leading to a free rider as a big part of the fiscal deficit of the city railway operators. However, there have been no previous researches on free pass riding, and especially, it is necessary to study free ride on private investment projects. Several alternatives including a full charge case, free-ride for 70 years old over case, and separate fare charge (900won) are considered. Separate fare charge (900won) was selected as the optimal alternative since there is no fare income adjustment between operating agencies and no subsidy from government.

Vibrio spp. and Streptococcus spp. have caused a considerable disease of farmed fish and economic loss in fish farming and seafood industry. In this study, the efficacy of an aquatic disinfectant tablet composed to calcium hypochlorite was evaluated against V. anguillarum and S. iniae. A bactericidal efficacy test by broth dilution method was used to determine the lowest effective dilution of the disinfectant following exposure to test bacteria for 30 min at $4^{\circ}C$. An aquatic disinfectant tablet and test bacteria were diluted with distilled water (DW), hard water (HW) or organic matter suspension (OM) according to treatment condition. V. anguillarum on the DW, HW and OM condition was completely inactivated with 16,000 15,000 and 13,000 fold dilutions of the disinfectant, respectively. On the DW, HW and OM condition, S. iniae was absolutely inactivated with 17,000 16,000 and 14,000 fold dilutions of the disinfectant, respectively. As an aquatic disinfectant tablet possesses bactericidal efficacy against fish pathogenic bacteria such as V. anguillarum and S. iniae this disinfectant solution can be used to control the spread of fish infective bacterial diseases.

Four cases of human infection by Echinochasmus japonicus (Trematoda; Echinostomatidae) were proven by the recovery of adult worms after a treatment with praziquantel (10mg/kg in single dose) and purgation in February 1984 in Korea. The patients were 3 middle-aged men and 1 elderly woman residing in a riverside village of Kangjin-gun (Tamjin river), Jeonranam-do, an ever-known endemic area of metagonimiasis. The treatment revealed numerous M. yokogawai worms together with 1-43 (total 54) specimens of E. japonicus and/or a few number of other kinds of trematodes or cestodes. The patients had gastrointestinal troubles such as indigestion and abdominal discomfort, probably due to these fluke infections. They have been eating some raw flesh of fresh water fishes such as cyprinoid ones or sweet fish caught from the river. This is the first record of human E. japonicus infection in the literature.

Objectives: In the past few years, herbal medicines have gained popularity over synthetic drugs because of their natural source and minimal side effects which has led to a tremendous growth of phytopharmaceuticals usage. With the development of nanotechnology, it provides alternative approaches to overcome several limitations using nano-formulations. In spite of considerable quantity of antianemic preparations with different iron forms available, currently additives are used and represented in modern pharmaceutical market. Iron deficiency anemia is a major global public health problem which particularly affects pregnant women, children and elderly persons. The situation is complicated because of disadvantages and drug side effects from existing antianemic medicines. There is a great demand for the development of new antianemic preparations. Green synthesis of iron oxide nanoparticles, possess high potential in this field. Methods: Our study focuses on developing green synthesis of iron oxide nanoparticles (IONPs) of 10-50 nm with spherical shape where different dosages were used -1 mg/kg, 10 mg/kg and 100 mg/kg for exposure in Wistar albino female rats for 28 days. The toxicity was assessed using various parameters such as measurements of the rat body and organ mass, hematology, biochemical evaluation and histopathological examinations. Results: No significant differences were observed in body and organ weights. Hematological indices also indicated no significant differences whereas biochemical factors showed increase in levels of direct bilirubin and globulin of medium as well as high dose and SGPT levels were increased only in high dose. The major organs (heart, kidney and liver) showed histopathological alterations in 10 and 100 mg/kg whereas brain showed only in 100 mg/kg. Conclusion: The toxicity of IONPs was found to be more significant when the concentration was increased; however, low doses can be used for further investigation as an antianemic preparation.

Background: This study aimed to reveal the clinicopathologic features and causes of bleeding in older patients with postmenopausal bleeding (PMB) and to investigate the correlation between the ultrasonographic findings and etiology of PMB. Methods: We retrospectively analyzed the causes and clinical characteristics of PMB in 498 patients who were diagnosed between January 2007 and December 2017. The population with PMB was divided into 2 groups according to age: Group A (n=204) included individuals more than 65 years of age and group B (n=294) included those less than 65 years of age. Clinical characteristics such as age, parity, underlying conditions, previous surgical history, and previous menopausal hormone therapy were compared between the groups. Cervical cytology testing and transvaginal ultrasonography were performed in all patients with PMB. Endometrial biopsy was performed in all cases of endometrial thickness ${\geq}5mm$. Results: We examined 498 patients with PMB. In group A, atrophic endometrium (n=125, 61.27%) was the most common cause of PMB. Twenty-three patients had gynecological malignancy (cervical cancer: n=12, 5.88%; endometrial cancer: n=8, 3.42%; ovarian cancer: n=3, 1.46%), and 30 patients had benign gynecological disease (endometrial polyp: n=10, 4.90%; submucosal myoma: n=6, 2.94%; uterine prolapse: n=7, 3.42%; cervical dysplasia; n=5, 2.45%; cervical polyp: n=2, 0.98%). Forty patients had endometrial thickness ${\geq}5mm$. Eight patients were diagnosed with endometrial cancer. All cases of endometrial cancer were diagnosed with endometrial thickness >10 mm. Conclusion: Atrophic endometrium was the most common cause of PMB in both groups, and approximately 12% of cases were associated with gynecological malignancy in older patients.

The purpose of this study was to examine the effectiveness of group forgiveness program for female elders who had deep and unfair personal hurt experiences from their social relationships. Subjects were divided into 2 groups. The sample was comprised of 20 elders, capable of verbal communication. Experimental and control groups composed of elders, each 2 elders dropped out of each group due to personal reasons. Experimental group completed a total of eight consecutive group forgiveness program sessions that combined listening and supportive techniques. Additionally, qualitative investigations were also done through interviews and observations. Following the intervention, experimental group experienced a significant improvement in degree of forgiveness(t=3.05, p<.01), anger(t=3.78, p<.01), anxiety(F=5.93, p<.05), depression(F=16.73, p<.01). Qualitative analysis also resulted that the elderly relationships were changing positively. This study implies that group forgiveness program was effective in improving elder's degree of forgiveness and reducing anger, anxiety and depression so that the participants were to value their whole life more.
