These days the aged have to live 30 or 40 years beyond the day they quit their day jobs. The quality of life for the elderly is a keen concern for the young people. We need to have a correct understanding of the age problem and the effort of a government or local government in order to bless the average life expectancy and not perceive it as a disaster. The number of the elderly living alone is increasing. Various types of support are needed to ensure that these people do not become socially isolated and are able to live alone. Supporting them includes activities to prevent social isolation that take their unique difficulties into consideration, which are different from the difficulties of supporting elderly people living with their families. In this research examined the current status of support activities for elderly people living alone and the unique difficulties involved in supporting them.

Accidental ingestion of caustic substance is one of the common problems among children around the world. Acid intake accounts for a mere 5% of all reported cases of corrosive ingestion in the West. Because of the esophageal sparing effect of acid, clinically significant esophageal involvement after acid ingestion occurs in only 6 to 20 percent of the instances. Despite effort of prevention, 7% to 15% of children sustaining caustic esophageal burns develop esophageal strictures. If balloon dilatation or bougie dilatation fails to resolve the esophageal strictures, successful outcome following replacement by colon or stomach has been reported in children. But the complications and morbidity following these operations are still relatively high. Seven patients with corrosive-acid induced esophageal strictures who were operated upon at the Department of Pediatric Surgery, Seoul National University Children's Hospital from 1991 to 1995 were reviewed. Primary resection and anastomosis was performed in all of 7 patients. The stricture involved short segments of the esophagus at the level of the lower cervical and the upper thoracic vertebra. The operations were approached through a left cervical incision or a left thoracotomy. In one patient, operative repair of anastomotic leakage was done, and three patients required re-resection of anastomotic strictures postoperatively, and one patient required a third operation(reversed gastric tube) due to an anastomotic stricture. The other anastomotic leaks, strictures or pulmonary complications were resolved with conservative treatment. In conclusion, primary resection and anastomosis of the esophagus was performed successfully on the 6 of 7 children with acid induced corrosive esophageal strictures. This approach is physiologic, especially in children who should have a long life expectancy, and recommended for the treatment of short-segment acid induced corrosive esophageal strictures.

Recently, as the non-face-to-face environment has developed due to COVID-19 and environmental pollution, the importance of online digital healthcare is increasing, and venture start-ups and activities such as health care, telemedicine, and digital treatments are also actively underway. This study conducted the impact on the acceptability of digital healthcare smartwatches with an integrated approach of the expanded integrated technology acceptance model (UTAUT2) and the behavioral inference model (BRT). The most advanced integrated technology acceptance model for innovative technology acceptance research was used to identify major factors such as utility expectations, social effects, convenience, price barriers, lack of alternatives, and behavioral intentions. For the study, about 410 responses from ordinary people in their teens to 60s across the country were collected, and based on this, the hypothesis was verified using structural equations after testing reliability and validity of the data. SPSS 23 and AMOS 23 were used for research analysis. Studies have shown that personal innovation has a significant impact on the reasons for acceptance (use value, social impact, convenience of use), attitude, and non-use (price barriers, lack of alternatives, and barriers to use). These results are the same as the results of previous studies that confirmed the influence of the main value of innovative ICT on user acceptance intention. In addition, the reason for acceptance had a significant effect on attitude, but the effect of the reason for non-acceptance was not significant. It can be analyzed that consumers are interested in new ICT products and new services, but purchase them more carefully and selectively. This study has evolved from the acceptance analysis of general-purpose consumer innovation technology to the acceptance analysis of consumer value in smartwatch digital healthcare, which is a new and important area in the future. Industrially, it can contribute to the product's purchase and marketing. It is hoped that this study will contribute to increasing research in the digital healthcare sector, which will play an important role in our lives in the future, and that it will develop into in-depth factors that are more suitable for consumer value through integrated approach models and integrated analysis of consumer acceptance and non-acceptance.

The purpose of PMO (Project Management Office) systems implementation in public sectors is to prevent the potential risks of IT projects with the project management for the electronic government, and to improve the quality of the project. As a leading country in software areas, PMO systems will play an important role to lead the best smart electronic government in the global world. This study suggested an operating model of PMO systems in public sectors in advance to use the PMO systems in public sectors by conducting a research investigating the key organizational role as the major factor which affects the behavioral intention of PMO systems implementation. We tested a hypothesis that Effort Expectancy factors and Facilitating Condition among the interested party groups will influence the Behavioral Intention of PMO systems implementation, and the result have given no difference to the Control Effect among the interested party groups. This study have shown that the interested party groups have common recognition about the Behavioral Intention of PMO systems implementation in the public sectors.

Puroose: In order to find out whether stereotactic radiation therapy (RT) using CyberKnife (CK) could improve survival rate and lower acute toxicity compared to conventional RT. Materials and Methods: From April 2003 through April 2004, 19 patients with Eastern Cooperative Oncology Group (ECOG) performance status ${\leq}3$ and locally advanced pancreas cancer without distant metastasis, evaluated by CT or PET/CT, were included. We administered stereotactic RT consisting of either 33 Gy, 36 Gy or 39 Gy in 3 fractions to 6, 4 and 9 patients, respectively, in an effort to increase the radiation dose step by step, and analyzed the survival rate and gastrointestinal toxicities by the acute radiation morbidity criteria of Radiation Therapeutic Oncology Group (RTOG). Prognostic factors of age, sex, ECOG performance score, chemotherapy, bypass surgery, radiation dose, CA 19-9, planning target volume (PTV), and adjacent organ and vessel invasion on CT scan were evaluated by Log Rank test. Results: The median survival time was 11 months with 1-year survival rate of 36.8%. During follow-up period (range $3{\sim}20$ months, median 10 months), no significant gastrointestinal acute toxicity (RTOG grade 3) was observed. In univariate analysis, age, sex, ECOG performance score, chemotherapy, bypass surgery, radiation dose, CA 19-9 level, and adjacent organ and vessel invasion did not show any significant changes of survival rate, however, patients with PTV (80 cc showed more favorable survival rate than those with PTV>80 cc (p-value<0.05). In multivariate analysis, age younger than 65 years and PTV>80 cc showed better survival rate. Conclusion: In terms of survival, the efficacy of stereotactic radiation therapy using CK was found to be superior or similar to other recent studies achieved with conventional RT with intensive chemotherapy, high dose conformal RT, intraoperative RT (IORT), or intensity modulated RT (IMRT). Furthermore, severe toxicity was not observed. Short treatment time in relation to the short life expectancy gave patients more convenience and, finally, quality of life would be increased. Consequently, this could be regarded as an effective novel treatment modality for locally advanced, unresectable pancreas cancer. PTV would be a helpful prognostic factor for CK.
