OBJECTIVES: To improve and promote mobile health monitoring services, this study investigated the perception of various factors influencing the acceptance of services between users and non-users. METHODS: This study drew 9 variables from studies related to mobile health monitoring services and the unified theory of acceptance and the use of technology model. A total of 219 samples were collected by a paper-based survey from users (n = 106) and non-users (n = 113). Analysis was carried out using a two-independent samples t-test. RESULTS: The findings indicate that users have a more positive perception of service benefits than non-users. Although there were difference between users and non-users, all respondents had a positive perception of the service benefits. After users used the service, they were less concerned about the risks involved with it. However, both users and non-users had a high negative perception of service risk. Users also had a more positive perception of intimacy and communication associated with the services than non-users. Both users and non-users had a high behavioral intention to use the services. Finally, this study observed that older subjects tended to recognize the higher value of the services. CONCLUSIONS: This study provides insights to improve and invigorate mobile health monitoring services. This study also offers insights into how to increase the number of users of mobile health monitoring services in South Korea.

Weight loss is physiologically beneficial in treating type 2 diabetes. Losing weight occurs when the body has a negative energy balance. However, many people have trouble in restricting their caloric intake. Strategies such as changing portion sizes, energy density and meal frequency can be useful for weight loss. Further research is needed on controlling food intake in the obese/overweight because of the complexity of eating behaviors.

Objectives: Distributed research networks (DRNs) facilitate multicenter research by enabling the use of multicenter data; therefore, they are increasingly utilized in healthcare fields. Despite the numerous advantages of DRNs, it is crucial to understand researchers' acceptance of these networks to ensure their effective application in multicenter research. In this study, we sought to identify the factors influencing the adoption of DRNs among researchers in Korea. Methods: We used snowball sampling to collect data from 149 researchers between July 7 and August 28, 2020. Five factors were used to formulate the hypotheses and research model: data accessibility, usefulness, ease of use, data security risk, and intention to use DRNs. We applied a structural equation model to identify relationships within the research model. Results: Data accessibility and data security were critical to the acceptance and use of DRNs. The usefulness of DRNs partially mediated the relationship between data accessibility and the intention to use DRNs. Interestingly, ease of use did not influence the intention to use DRNs, but it was affected by data accessibility. Furthermore, ease of use impacted the perceived usefulness of DRNs. Conclusions This study highlighted major factors that can promote the broader adoption and utilization of DRNs. Consequently, these findings can contribute to the expansion of active multicenter research using DRNs in the field of healthcare research.

PURPOSE: To evaluate the usefulness of real-time ultrasound-guided biopsy as an aid in diagnosing pleural attached lung lesions. MATERIALS AND METHODS: Over a 2-year period (March 1992 through February 1994), 52 US-guided diagnostic biopsies were performed in 50 patients with peripheral lung lesions in contact with chest wall. 15 cases were performed with gun biospy and 37 cases with fine needles. Final diagnosis was confirmed by surgery and clinical follow-up. RESULTS: In 44 of 52 cases(84.6%), we obtained histologic or cytologic material by US-guided biopsy. Diagnostic accuracy and tissue type specific accuracy for malignancy were 83.9%(26/31) and 67.7% (21/31), respectively. Eighteen case% were reported to be benign and one of them was proven to be metastatic lesion. We could not find any complications such as hemoptysis or pneumothorax. CONCLUSION: Ultrasound-guided biopsy is a simple, safe and accurate diagnostic procedure for evaluation of peripheral lung lesion attached to the pleura.

OBJECTIVE: The primary purpose of the present study is to determine the diagnostic accuracy of Kernig's sign, Brudzinski's sign, nuchal rigidity, and Jolt accentuation of headache for children suspected of meningitis. This study focuses on the clinical symptoms and signs of meningeal irritation and their relationship to the CSF pleocytosis. METHODS: We examined these meningeal irritation signs before lumbar puncture from the patients who visited Chosun University Hospital and were suspected of meningitis. RESULTS: A total of 70 children(age>4) were enrolled over 12 months. Kernig's sign (sensitivity : 41%, specificity : 77%), neck stiffness(sensitivity : 76%, specificity : 41%), and Jolt accentuation of headache(sensitivity : 76%, specificity : 48%) did not accurately discriminate the patients with meningitis(> or =6 white blood cells/mL of CSF) from the patients without meningitis. But Brudzinski's sign(sensitivity : 64%, specificity : 70%, P< 0.05) was valuable to predict the CSF pleocytosis. Among the clinical symptoms, nausea, vomiting, fever and headache(P<0.05) were shown to have diagnostic values. CONCLUSION: The objectification of neurologic sign is demanded and better bedside diagnostic tests are needed.

Temporal triangular alopecia is a triangular or oval shaped non-scarring alopecia, occurring on the temporal side of the scalp, which was first reported by Sabourand in 1950. It usually occurs in the childhood. There is no treatment for this disorder except for surgery. In this article, we report a case of focal alopecia which was successfully treated with micropigmentation.

To determine the salinity of packaged Kimchi, bulk Kimchi and other common foods, we collected samples of foods from the Gyeonggi province area in October 2006 and determined the salinity levels in one serving portion. The average salinity of all foods was 0.226+/-0.212%. The average salinity of all Kimchi samples was 0.401+/-0.260%. The average salinities of soups, stews, protein containing side dishes, vegetable side dishes and drinks were 0.153+/-0.085%, 0.691+/-0.213%, 0.157+/-0.102%, 0.209+/-0.127% and 0.080+/-0.076%, respectively. The average salt intake of one serving of Kimchi was 0.125+/-0.041 g, while the average salt intakes of one serving of the soups, stews, protein containing side dishes, vegetable side dishes and drinks were 0.306+/-0.170 g, 1.382+/-0.426 g, 0.094+/-0.061 g, 0.146+/-0.089 g, and 0.159+/-0.152 g, respectively. The salinity of packaged Kimchi was significantly higher than the salinity of the bulk Kimchi (p<0.01). In addition, the salinity of the liquid and solid stem portions of the packaged Kimchi was significantly higher than the salinity of the same sized portions of the bulk Kimchi (p<0.01). Furthermore, the salinity in the liquid and solid stem portions of the packaged mustard leaf Kimchi were significantly higher than the salinities of other types of Kimchi (p<0.0001). The salinity of all Kimchi is higher than that of soup, protein containing side dishes, vegetable side dishes or drinks, but the salt content of one serving of Kimchi is lower than those of the soups or stews or vegetable side dishes or drinks (because one serving size of Kimchi is usually smaller than that of the other foods).
