Objectives : DongUiBoGam is a representative medical literature in Korea. This research intends to structurally grasp how DongUiBoGam understands the human body and review the methods of acupuncture and moxibustion in the NaeGyeong chapter of it using text mining. Methods : The structure of DongUiBoGam was analyzed with specific parts of the book that described contents, major premises of understanding the human body, and processes of treatment. We analyzed characteristics of each acupoints in a relationship with causes of diseases & symptoms in the NaeGyeong chapter using a Term Frequency - Inverse Document Frequency(TFIDF). Results : Three different categories of pattern identification(PI) were formed after structural analysis of DongUiBoGam. Every causes of diseases & symptoms were transformed according to the three categories of PI. After analyzing the relationship between acupoints and causes of diseases & symptoms, 114 acupoints were visualized with TFIDF values of three PI categories. Conclusions : The selection of acupoints in NaeGyeong chapter of DongUiBoGam were linked to causes of diseases & symptoms based on the three PI categories. Through visualization of bipartite relationships between acupoints and causes of diseases & symptoms, we could easily understand characteristics of each acupoint.

The medical treatment is process of collecting symptoms, making a diagnosis and treatment for the diagnosis. The remedy and the efficacy are the important hinge that links the diagnosis to the means of medical treatment. Lots of medical data are stored on database or saved as files in these days. The preferential way to find the efficacy related to the remedy is search all efficacy terms match up to the remedy term. To increase the rate of matching remedy terms with efficacy terms, we study the relation between efficacy terms and remedy terms and research the conversion way of the terms into the representative terms. The rate of matching the raw remedy terms with the raw efficacy terms is below 30%. The rate of matching the disaggregate remedy terms with the disaggregate efficacy terms is about 50%. The rate of matching the representative remedy terms with the representative efficacy terms is almost 70%.

Background: This study examined the relationships of dementia, stroke, and combined multimorbidity with long-term care utilizations among older people in South Korea. Methods: A nationally representative sample of 10,130 older adults who used long-term care services in 2010 were analyzed. We used the 5% sample of aged 65 years or older linked with National Health Insurance Corporation registry data of long-term care insurance system. The sample was categorized into three groups: dementia only (47.6%), stroke only (36.3%), and both dementia and stroke (16.1%). We estimated the use of institutional care, home care, and total expenditure of long-term care services, adjusting for the severity of each function (such as daily life, behavior or cognitive change, nursing care needs, and rehabilitation care needs) and sociodemographic characteristics. Results: Having dementia symptoms was positively associated with the use of institutional care services, on the other hand, having stroke symptoms was positively related with the use of home care. The total long-term care cost was higher in the group of having both dementia and stroke. Conclusion: Older persons with dementia symptoms and stroke symptoms have different patterns of long-term care utilization, and the multimorbidity increased the overall expenditure of long-term care utilization. These findings imply a need for differentiated management strategy targeting physically and cognitively impaired older persons, and special concerning for persons with multimorbidity conditions for long-term care insurance program in Korea.

Unnatural working postures usually cause musculoskeletal problems for workers in work field, especially in traditional industry. Many analysis and survey methodologies have been developed to identify unnatural postures and disorder risks in workplaces. The Ovako Working Posture Analyzing System (OWAS) and Nordic Musculoskeletal Questionnaire (NMQ) are the representative methods and applied widely. This study applied the both tools to investigate the work field of a manufacturing factory of the water heater's case. We divided the manufacturing process into nine workshops, took the pictures of working motions by DV camera and analyzed the postures on OWAS. From the OW AS results, we could identify the risks level of musculoskeletal symptoms as four Action Categories (AC). And from the comparison of OWAS and NMQ results, we could provide the suggestions to improve the working methods and environment. From the results of OWAS, we found that the operators' head/neck and back were above AC3 in some workshops. If the situation continued in long period, the operators might have the risk to get musculoskeletal symptoms. From the investigation of NMQ, we also found that the percentage of aches on neck, shoulders and lower back were higher than other parts of body. The correlation between aches and jobs was more than 75%. So we provided some suggestions to improve: work rotation and adjustment of work surface/height to fit in with Ergonomics. Then the risks of musculoskeletal symptoms would be reduced.

This research aims to find a way to utilize the literature to select the herbs to be added or subtracted according to the condition of the patient after determining the basic prescription to be used for the patient. The study is based on data concerning the herbal composition and application of prescriptions described in the Donguibogam. The composition herbs was expressed as a weight ratio, the standard deviation of the weight ratio was calculated for each prescription, and the case where the weight ratio was greater than the base value (highest weight ratio - standard deviation) was designated as a principal herb. The various expressions of applications were changed to representative terms by the researcher and used to calculate the frequency. Of the 4,373 prescriptions for Donguibogam, 3,307 were able to be expressed in terms of weight ratios with 640 prescriptions using Rehmannia glutinosa, Cnidium officinale, Angelica gigas and Paeonia lactiflora as the principle herb. Of the 640 prescriptions, 508 prescriptions included applied information. Rehmannia glutinosa can also be used for symptoms such as fetal leakage(胎漏), short ingestion(食少), fever(發熱), dazed expression(眼花). Cnidium officinale can also be used for symptoms such as migraine(偏頭痛), stroke(中風癱瘓), tetanus(破傷風). Angelica gigas can also be used for symptoms such as forgetfulness(健忘), incontinence of urination(小便不通), palpitations(驚悸). Paeonia lactiflora can also be used for symptoms such as heart pain and abdominal pain(心腹痛), cough(咳嗽).

Purpose: The COVID-19 pandemic, which emerged in late 2019, had a profound impact on global public health and disrupted the daily lives of people worldwide. Particularly, university students faced a challenging situation as their university life underwent a drastic transformation due to long-term remote learning and isolation measures. This study aimed to investigate the relationship between changes in daily life during the 2020 COVID-19 pandemic and depressive symptoms among university students aged between 19 and 29 in Korea. Methods: We analyzed data from the nationally representative 2020 Community Health Survey (CHS). Among the 229,269 participants, 9,279 university students aged 19-29, either enrolled or on leave, were selected. After excluding 401 cases with missing values, the final sample comprised 8,878 individuals. Using multivariate logistic regression with a complex sample design, we explored the association between daily life changes during the COVID-19 pandemic and depressive symptoms. Results: Changes in daily life during the COVID-19 pandemic was associated with depressive symptoms in Korean university students aged 19 to 29, even after adjusting for sociodemographic characteristics, health-related factors, and COVID-19-related aspects (OR=1.28, 95% CI=1.09~1.50). Conclusion: Our study suggests that when examining the impact of COVID-19 on health issues, it is crucial to consider the changes in daily life caused by the pandemic. These findings can provide insights into the psychological well-being of university students during times of crisis.

Objective and Background : Attempt to express knowledge by IT is the current of the times, knowledge of the oriental medicine have to meet the needs of the times. It takes 'classification system of the oriental medicine terms' and 'system of the predicate' for explaining the relation between concepts to express knowledge by IT technique. Researches for 'classification system of the oriental medicine terms' are in progress already, researches for 'system of the predicate' are insufficient. Subject of study : We proceeded to study of the predicate in Idongwon(李東垣)'s "Biwiron(脾胃論)" has clear theory system and considerable influence upon knowledge of the oriental medicine for studying 'system of the predicate' which expresses knowledge of the oriental medicine in early stage. Method : Acquire Chinese play a predicate part in "Biwiron(脾胃論)", translate the Chinese to answer the context, group the similar predicate, decide representative predicate of group. And attempt to make classification system of the representative predicate with Term management system based on SQL Server 2005. Results and Considerations : I classify the predicate which predicate diagnosis, treatment, symptoms and knowledge of the oriental medicine into existence, condition, cognition and will. This classification seems to be useful to explain factors which have an effect on demonstration and treatment.

Objectives: This article reviewed research on smoking behaviors and smoking-related health problems among university students to suggest evidences for developing smoking control strategies for them. Methods: Domestic research papers were screened through Research Information Sharing Service (RISS), Koreanstudies Information Service System (KISS), Medical Library Information System (MEDLIS), Korean Medical Database (KMbase), and digital national assembly library. International papers were searched mainly via PubMed. Results: Smoking prevalence among male college students were found to be over 50% in majority of Korean studies. While studies on smoking-related health problems were scant in Korea, several recent studies overseas showed possible effects of smoking on health among young adults, including decreased lung function, respiratory symptoms, cardiovascular problems, glucose intolerance, buccal disease, depressive symptoms, and so forth. Besides, smoking behaviors were closely related with other risk behaviors including drinking, and several psychosocial factors. Conclusions: To explore the smoking problem among college students, the first step should be a national representative survey with scientific methods. More research should be focused on the smoking-related problems among college students. To prevent smoking among college students, smoking prevention education, and smoking cessation counseling, and the initiatives of smoke free campus are needed.

Background: Older age is associated with an increase in the incidence of cancer cases. Diagnosis and treatment of cancer in older adults can be stressful because of health decline related to age, comorbidities and inadequate treatment for pain and other symptoms of the disease. This survey is one of the unique studies in Jordan and in the Arab world that aimed at exploring the predictors of older adult individuals awareness towards cancer. Materials and Methods: A stratified random sampling technique was followed to reach a representative sample of 753 participants. The questionnaire of the study consisted of parts regarding demographic variables, awareness about screening tests, and signs and symptoms of cancer. In addition, specific questions related to factors linked to cancer were included. Cross-sectional design was adopted with face-to-face interviews at the interviewees' households. Results: The mean age of the participants was about 63 years; around 44% of them are above the age of 65 years. 'Being convinced that having no health problem makes the individual feel safe and not at risk of getting cancer' was the major reason for not doing a routine health check-up. Conclusions: The low levels of awareness about cancer, as well as the low use of the screening methods were crucial outcomes of this study. Thus, raising the awareness among health care providers and policy makers in the country about older adults' perception of cancer is a high priority.

Reinforcement corrosion can cause serious safety deterioration to aging concrete structures exposed in aggressive environments. This paper presents an approach for reliability analyses of deteriorating reinforced concrete structures affected by reinforcement corrosion on the basis of the representative symptoms identified during the deterioration process. The concrete cracking growth and rebar bond strength evolution due to reinforcement corrosion are chosen as key symptoms for the performance deterioration of concrete structures. The crack width at concrete cover surface largely depends on the corrosion penetration of rebar due to the expansive rust layer at the bond interface generated by reinforcement corrosion. The bond strength of rebar in the concrete correlates well with concrete crack width and decays steadily with crack width growth. The estimates of cracking development and bond strength deterioration are examined by experimental data available from various sources, and then matched with symptom-based lifetime Weibull model. The symptom reliability and remaining useful life are predicted from the predictive lifetime Weibull model for deteriorating concrete structures. Finally, a numerical example is provided to demonstrate the applicability of the proposed approach for forecasting the performance of concrete structures subject to reinforcement corrosion. The results show that the corrosion rate has significant impact on the reliability associated with serviceability and load bearing capacity of reinforced concrete structures during their service life.
