At present, our society is developing into the intelligent information society in the wave of the 4th industrial revolution, and this change will have the positive effect of innovating all industry fields. However, due to the duality of technology, there will be positive and negative effects. With intelligence, threats to cyber dysfunction such as hacking, terrorism, privacy infringement, and illegal content distribution will become more serious. Until now, the security system of the Internet has been a proactive security system, but in recent years, a proposal for a trust network, a preventive security system, has been introduced. Therefore, this study aims to analyze the possibility of resolving cyber dysfunction of intelligent information society about Bright Internet, one of trust network technologies. This study defines the cyber dysfunction of the intelligent information society and analyzes the perceptions of changes in the cyber dysfunction of the intelligent information society on the introduction of the five principles of the Bright Internet. The change of cyber dysfunction severity of the intelligent information society due to the introduction of the trust network is analyzed to reflect the technical and social demands. This work will guide the structure of the trust network and the direction of practical technological introduction and its influence.

Objectives : The aim of this study was to perform network analysis and analysis using the K-HERB database on inflammatory bowel disease (IBD), to verify the similarity between the derived networks and existing prescriptions, and to explore the possibility of developing new IBD prescriptions preliminarily. Methods : We conducted a comprehensive literature search on July 6, 2024, utilizing databases such as ScienceON, RISS, and OASIS. Clinical studies assessing the efficacy of herbal medicine in treating Crohn's disease and ulcerative colitis were identified and compiled into a structured database. This dataset, which included related prescriptions and herbal formulations, was subsequently analyzed using NetMiner 4 for centrality and Louvain clustering analyses. We then compared the networks derived from the K-HERB database with existing therapeutic prescriptions to assess their similarity. Results : A total of 24 prescriptions and 66 herbs were identified across the surveyed studies on IBD. Paeoniae Radix Alba(白芍藥) emerged as the most frequently utilized herb for both Crohn's disease and ulcerative colitis. Prominent herb combinations included Paeoniae Radix Alba-Angelicae Sinensis Radix (白芍藥-當歸), Angelicae Sinensis Radix-Coptidis Rhizoma (當歸-黃連), and Coptidis Rhizoma-Scutellariae Radix (黃連-黃芩) for ulcerative colitis. Centrality analysis revealed that Poria cocos (茯苓) and Paeoniae Radix Alba (白芍藥) had high centrality in the Crohn's disease, while Angelicae Sinensis Radix (當歸) and Paeoniae Radix Alba (白芍藥) had high centrality in the ulcerative colitis, indicating their prominent roles within the networks. Cohesion analysis resulted in 7 networks for Crohn's disease and 16 networks for ulcerative colitis. After excluding networks with a single herb, three networks related to Crohn's disease and two related to ulcerative colitis were examined using the K-HERB database. Among the 14 derived prescriptions for Crohn's disease and seven for ulcerative colitis, all except Oryeong-san (五苓散) were non-traditional in the context of IBD treatment. Conclusion : This preliminary study may provide a basis for the understanding and application of herbal prescriptions for IBD based on network analysis and the K-HERB database.

Objectives: Studies investigating problematic internet use have increased rapidly and have been focused on its causes, psychopathology, prevalence, characteristics and so on. However, there are few studies concerning the correlation between problematic internet use and youth health risk behavior. Therefore, the purpose of this study was to examine the relationship between problematic internet use and youth health risk behavior. Methods: A community sample of 632 high school students in grades 10 and 11 was collected for the survey. The sample was assessed using the Youth Risk Behavior Surveillance System(YRBSS) and Young's Diagnostic Questionnaire of Internet Addiction(YDQ). The subjects were classified into two groups: normal and problematic internet use, and the problematic internet use group was further divided into at-risk use and addiction groups. Results: There were 56 subjects(8.9%) in the internet addiction group and 56 subjects(8.9%) in the at-risk internet use group. The other 507 subjects were classified as normal. The subjects in the internet addiction group kissed more frequently and ate less fruit than those in the normal group. They also showed a relatively higher tendency to watch TV, ride in a car driven by a drunk driver and to carry a weapon than those in the normal group. There were no differences in health risk behaviors between the subjects in the internet addiction group and those in the at-risk internet use group, except for the possibility of riding in a car driven by a drunk driver. Conclusion: Unlike the normal group, there was very little difference in health risk behavior between the internet addiction group and the at-risk internet use group, which indicates that the addiction group and the at-risk internet use groups are homogenous. It is important to focus on the behavior of individuals in the at-risk group, and preventive measures should be taken in order to reduce the possibility of at-risk adolescents becoming addicted.

The purpose of this study was to examine the relationship among potential job-related risks, emotional dissonance, and job turnover intention of caregivers at the long-term care facilities in South Korea, and to explore the potential mediator role of burnout in this association. For the study, survey data of 434 caregivers at long-term care facilities were collected and analyzed using structural equation modeling method. The results showed that high level of caregivers'perception of the potential job-related risks led to increased burnout and turnover intention of caregivers. Second, caregivers'burnout partially mediated the effect of the potential job-related risks on turnover intention. Third, the more caregivers experience emotional dissonance, the higher the possibility of caregivers'burnout. On the other hand, emotional dissonance of caregivers did not give significant direct impact on turnover intention. Burnout fully mediated the relationship between emotional dissonance and turnover intention of caregivers. Lastly, the more caregivers experience burnout, the higher possibility of turnover intention. Based on the results, researchers suggested possible intervention methods as well as preventive measures to reduce the turnover of caregivers at long-term care facilities.

Aflatoxin $B_1$, a known human carcinogen, is the member of aflatoxin subfamily that is most frequently found in contaminated foods. Epidemiological studies have suggested that aflatoxins may be associated with human liver cancer and acute hepatitis. Recently it was reported that the traditional medical herbs sold in domestic markets are contaminated with aflatoxins. Long-term administration of these contaminated medicines could result in adverse health effects. Therefore, it is important to evaluate the levels of exposure to aflatoxin in people who ingest traditional herbal medicines. Blood samples were collected, before and after the herbal medicine intake, from 151 subjects who visited the hospital. The metabolite of aflatoxin $B_1$ in blood, aflatoxin $B_1$-albumin (aflatoxin $B_1$-lysine), is reportedly an appropriate internal exposure indicator, and its levels in the collected bloods were therefore analyzed using a liquid chromatography-mass spectrometry. The analytical method of aflatoxin $B_1$-lysine in blood was firstly optimized in Korea and the levels were detected below quantification limits (2 pg/mg albumin) in this study population. Consequently, the exposure levels of aflatoxin $B_1$ by ingestion of herbal medicines were low but it is important to monitor routinely due to the possibility of risk on the aflatoxin exposure.

Recently, the oriental medicine industry in Korea has faced much hardship, due to the decreasing number of patients. Therefore, it is essential to investigate the reasons why patients are avoiding oriental medicine, because the percentage of people consuming medical service is an important marker that assesses the value of medical service. The researcher(s), based on theories on factors that affect health, health behaviors, and diseases, sought to find reasons why oriental medicine clinics saw a decline in the number of patients. Also, by proposing the problems inside the oriental medicine, I came to the following conclusion. -Because Koreans have low expectations for oriental medicine, they do not consider it as full medical service. Also, when they get sick, they are reluctant to seek oriental medicine because of reasons such as the limits of oriental medicine and check-ups, expensive medical cost, negative perception of oriental medicine, not enough support from the media, the old image of the oriental medicine and the little power the industry has on the society. -Among the inner problems of the oriental medicine community was the limitations that the science face on incurable and chronic diseases in terms of treatment and management, little professionalism, lack of scientific evidence, the attitude of the oriental medicine society, lack of sophistication in research methodology, and limitations in responding to changes in public health and the surroundings. The purpose of medicine is to eliminate the possibility of shortened life and dangers by treatment of diseases and health maintenance. For this to happen, structural and developed medical theories and means of treatment are necessary. The researcher hypothesizes that the problems that the oriental medicine society is facing mainly come from the lack of efforts and ability to provide such necessities.

A 7-year-old, intact female Yorkshire terrier dog was presented for coughing, anorexia, chest pain and dyspnea. Right lateral thoracic radiograph demonstrated a large mass shape on the heart base with decreased cardiac silhouette and severe right deviation of the trachea with the heart shifted to the left thoracic wall was observed on the ventrodorsal thoracic projection. Echocardiographic examination revealed a large rounded mass compressing left atrium around the heart base without signs of pericardial effusion. On computed tomographic (CT) findings, sagittal CT images depicted the possibility of cranial vena caval invasion and heart base involvement of the mass associated with biatrial compression. Dorsal CT image revealed the right deviation of trachea due to the heart base mass and markedly shrunk lung space was detected on the transverse CT image. Because the dog suddenly had died during the recovery from anesthesia after finishing CT scan, necropsy was performed. On gross findings, a large and lobulated mass was located at the base of the heart. A poorly-demarcated, infiltrative, multilobulated tumor composed of polyhedral cells in solid cellular sheets was confirmed based on histopathologic examination. This dog was diagnosed as a chemodectoma. This case report describes the clinical findings, diagnostic consistency of thoracic radiography, echocardiography and CT, and histopathologic confirmation in a spontaneously occurring chemodectoma with a Yorkshire terrier dog.

This study was designed to investigate the hypoglycemic effects of Benincasa hispida (Wax gourd) in streptozotocin (STZ)-induced diabetic rats. Diabetes was induced in the male rats by intravenous injection of STZ at a dose of 45 mg/kg dissolved in citrate buffer. The diabetic animals then had plasma glucose concentration of above 300mg/dl. The experimental groups were divided into five groups; normal, STZ-control and three Wax gourd groups (5%, 10% and 20% intake groups). Normal and STZ-control groups were fed on a AIN-93 diet and experimental groups were fed a AIN-93 diet with the Wax gourd powder (5%, 10% and 20%/kg diet) for 4 weeks. The body weight, diet intake and feed efficiency ratio (FER) were monitored. The blood glucose and cholesterol levels were determined everyweek. After 4 weeks, the rats were sacrificed and the levels of glucose, insulin, cholesterol, HDL-cholesterol, triglyceride and free fatty acids in plasma and levels of glycogen in liver and muscle were analyzed. Diabetic rats showed the lower weight gain compared to the normal rats. The weight gain and feed efficiency ratios in 15 and 20% Wax gourd groups were higher than in STZ-control group. The plasma glucose levels were significantly lower in all Wax gourd groups than in STZ-control group. The plasma insulin levels in diabetic groups were not significantly different compared to the normal group, but the level of 20% Wax gourd group was higher than other diabetic groups. The experimental diabetic groups showed the higher levels of muscle glycogen compared to STZ-control group. The lower levels of plasma cholesterol were noticed in 20% Wax gourd group throughout the experimental period. The plasma level of triglyceride was elevated in STZ-diabetic control and the levels were slightly decreased in Wax gourd groups. Rats of 10% Wax gourd group showed the lower levels of plasma free fatty acids. It is suggested, from the results, that the possibility of therapeutic or preventive use of wax gourd to the diabetes mellitus.
