The purpose of this study is to examine the association between resistance exercise frequency, muscular strength, and health-related quality of life in Korean cancer patients. We performed complex sample general linear model and logistic regression analysis using data from a total of 647 cancer patients in the 2014~2016 Korean National Health and Nutrition Examination Survey (KNHANES). Participants who were participating in resistance exercise 0~1 day per week had lower EQ-5D index (0.852±0.016 vs. 0.890±0.020; p=0.006) and a significantly higher risk of having problems in mobility (Odd ratio[OR]=4.07; 95% confidence interval [CI]=1.31-12.63) compared to those who were participating in resistance exercise ≥ 5 days per week. Participants with low hand-grip strength had lower EQ-5D index (0.850±0.018 vs. 0.911±0.016; p<0.001) and a significantly higher risk of having problems in mobility (OR=4.94, 95% CI=2.14-11.41), usual activities (OR=5.18, 95% CI=1.56-17.14), and pain/discomfort (OR=2.46, 95% CI=1.33-4.55) compared to those with high hand-grip strength. This study showed that resistance exercise frequency and muscular strength were associated with health-related quality of life in Korean cancer patients.

The purpose of the study was to examine the effect of resistance training on joint flexibility and muscle strength of upper extremities of institutionalized elderly with impaired cognition. The study design was pretest-posttest control group study and inclusion criteria were elderly aged 65-year older, MMSE score 23 or less, ones who had no serious physical and/or mental problem except impaired cognition, and were capable to carry out resistance training. After consents were obtained participants were randomly assigned. Pre-post evaluation was performed by staff nurses trained beforehand. Among those 4-week study period, experiment was carried out during 5 consecutive days a week for 3 weeks. ROM and extension range of shoulder joints and muscle strength of shoulders and hands for both sides were measured. Flexion, extension, abduction range of right shoulder joint was significantly improved. Flexion and extension muscle strength of left side shoulder and abduction muscle strength of both sides of shoulder were significantly improved. With the study result, it could be concluded that resistance training has therapeutic effects on joint flexibility and muscle strength. More studies adopted longer experimental period to evaluate timing of effect and extinction to refine the protocol are called for.

This research, with the participants of the female elderly using a home-visit bath among long-term care services, made an in-depth analysis of what they experience while getting a home-visit bath. We conducted in-depth interviews with 8 elderly people. According to the result, the female elderly experienced the absence of a caregiver, difficulty in carrying out daily life due to physical diseases, getting what they need by themselves, getting comfortable in body and mind, accepting their given situation though feeling shame at getting a bath, and expressing their desires. In addition, they had a close relationship with a care helper. On the basis of the results, a systematic training system which could intensify the professionalism of care helpers was suggested. For the enhancement of the elderly's emotional stability in a long-term care, an integrated case management system was also suggested, which supports the family by organizing an integrated network by region between a long-term care service, home-visit care service, welfare center, and the National Health Insurance Corporation.

This study was conducted to investigate the types of personality of North Korean female refugees, which were extracted from the T-scores of SPFQ(scales of the Sixteen Personality Factor Questionnaire) and psychological adaptation. For this, The data of 158 North Korean female refugees located in Seoul Yangchun-Gu and Gayang-Gu was analyzed. The results were as follows. Firstly, the ratio of over 65T in ego-strength, self-control, social-boldness, anxiety scales and under 34T in abstractedness and openness to change scales was higher than in other scales. Secondly, there were statistically significant differences in personality characteristics based on the demographic variables especially age and the term of residence in South Korea. Thirdly, three distinct groups were extracted from the K-means cluster analysis. The first group was characterized with emotional-unstability and negative emotionality. And the North Korean female refugees in the second group hesitated to enter into and maintain proper relationships with south korean, while they were unlikely to accept norms and rules in South Korea. The third group, characterized by higher emotional stability, ego-strength, and agreeableness, was met normal range in all the scale of SPFQ. Finally, each three groups were showed statistically significant differences in psychological adaptation scales(self-identity and resilience). We expected that these results contributed to explore the psychological and the political plans for North Korean female refugees' settlement in South Korea.

We report an unusual case of postoperative early gastric cancer with liver metastasis mimicking pancreaticobiliary carcinoma. A 73-year-old man with early gastric cancer was transferred for endoscopic treatment. The patient underwent endoscopic submucosal dissection for the treatment of the early gastric cancer. The pathological diagnosis was adenocarcinoma with extension to the deep submucosa and some lymphatic invasion. Therefore, subsequent a subtotal gastrectomy was performed. The histological results demonstrated residual adenocarcinoma confined to the mucosa. The resection margin and lymph node metastasis were negative. Thus, he was closely monitored for recurrence every 6 months. After 2 years, he was suddenly suspected of developing liver metastasis and local recurrence. He received a liver biopsy, and the pathological result was poorly differentiated adenocarcinoma. Immunohistochemical staining suggested pancreaticobiliary carcinoma rather than metastatic adenocarcinoma from the stomach or colon, but primary focus was not found. We were sure that the recurrent stomach cancer metastasized to the liver because stomach cancer can show heterogeneous cytokeratin (CK) expression pattern with various histological features. Therefore, no single CK expression pattern has diagnostic value for distinguishing gastric carcinoma. The patient underwent chemotherapy for metastatic stomach cancer.

Many studies have demonstrated that family plays a crucial role in health and wellbeing in life. There has been little research, however, examining the relative importance of activities together with family members in middle-aged adults. The goal of this study was to examine the effect of family meal, phone conversation with family, and family leisure activities on happiness, health, and family relationship. Total 286 middle-aged adults (M=50.13) participated in this study. Dependent variables were happiness (SWB), physical and psychological illness symptoms, family satisfaction, sex satisfaction, and parenting sense of competence. This research showed that (1) frequency of meal with family was positively correlated with happiness, family relationship, and negatively physical/psychological illness symptoms; (2) high frequency of talking on the phone with family resulted in that high level of happiness, family satisfaction, sex satisfaction, and parenting sense of competence, and lower illness symptoms; (3) the more participants spent leisure time with family, the happier and the more family satisfaction they feel. Findings suggest that activities together with family members in middle-aged adults may enhance their happiness, health, and quality of family relationship. The implication for current study were discussed.

The development of information and communication technology and the improvement of the development and dissemination of smart devices have caused changes in the form of tourism, and the concept of smart tourism has since emerged. In this regard, researches related to smart tourism has been conducted in various fields such as policy implementation and surveys, but there is a lack of research on application reviews. This study collects Trip Advisor application review data in the Google Play Store to identify usage of the application and user satisfaction through Latent Dirichlet Allocation (LDA) topic modeling. The analysis results in four topics, two of which are positive and the other two are negative. We found that users were satisfied with the application's recommendation system, but were dissatisfied when the filters they set during search were not applied or that reviews were not published after updates of the application. We suggest more categories can be added to the application to provide users with different experiences. In addition, it is expected that user satisfaction can be improved by identifying problems within the application, including the filter function, and checking the application environment and resolving the error occurring during the application usage.

The progressive wear of teeth is a physiologic process of aging, but excessive wear can lead to occlusal disharmony, tooth sensitivity and pulp exposure, decreased masticatory efficiency, and aesthetic problems. It should be treated by evaluating the cause of tooth wear and establishing a stable centric relation with appropriate vertical dimension of occlusion and occlusal plane. The present case report successfully rehabilitated a full-mouth case of a severely worn dentition with the use of digital facebow transfer and virtual articulator.

In modern society, blind people face difficulties in navigating common environments such as sidewalks, elevators, and crosswalks. Research has been conducted to alleviate these inconveniences for the visually impaired through the use of visual and audio aids. However, such research often encounters limitations when it comes to practical implementation due to the high cost of wearable devices, high-performance CCTV systems, and voice sensors. In this paper, we propose an artificial intelligence fusion algorithm that utilizes low-cost video sensors integrated into smartphones to help blind people safely navigate their surroundings during walking. The proposed algorithm combines motion capture and object detection algorithms to detect moving people and various obstacles encountered during walking. We employed the MediaPipe library for motion capture to model and detect surrounding pedestrians during motion. Additionally, we used object detection algorithms to model and detect various obstacles that can occur during walking on sidewalks. Through experimentation, we validated the performance of the artificial intelligence fusion algorithm, achieving accuracy of 0.92, precision of 0.91, recall of 0.99, and an F1 score of 0.95. This research can assist blind people in navigating through obstacles such as bollards, shared scooters, and vehicles encountered during walking, thereby enhancing their mobility and safety.
