In the current field of Medical Informatics, the information increases, and changes fast, so we can access the various data types which are ranged from text to image type. A small number of technician digitizes these data to establish database, but it is needed a lot of money and time. Therefore digitization by many end-users confronting data and establishment of searching database is needed to manage increasing information effectively. New data and information are taken fast to provide the quality of care, diagnosis which is the basic work in the medicine. And also It is needed the medical database for purpose of private study and novice education, which is tool to make various data become knowledge. However, current medical database is used and developed only for the purpose of hospital work management. In this study, using text input, file import and object images are digitized to establish database by people who are worked at the medicine field but can not expertise to program. Data are hierarchically constructed and then knowledge is established using a tree type database establishment method. Consequently, we can get data fast and exactly through search, apply it to study as subject-oriented classification, apply it to diagnosis as time-depended reflection of data, and apply it to education and precaution through function of publishing questions and reusability of data.

Pyogenic liver abscess with metastatic septic complications is a rare and serious infectious disease if not treated properly. Pyogenic liver abscesses are caused by bacterial, fungal, or parasitic organisms. Escherichia coli used to be the predominant causative agent, but Klebsiella pneumoniae emerged as a major cause in the 1990s. Liver abscesses are caused by hepatic invasion via many routes, such as, the biliary tree, portal vein, hepatic artery, direct extension, or penetrating trauma. Furthermore, diabetes mellitus and malignant conditions are established important risk factors of K. pneumoniae liver abscesses and of septic metastasis, and several recent studies have asserted that K. pneumoniae liver abscess might be a presentation of occult or silent colon cancer. We report a case of K. pneumoniae liver abscess, metastatic septic pulmonary embolism, and endophthalmitis associated with diabetes and advanced gastric cancer.

The results are as follows. 1. Oriental medical terms which express abnormal sensations are Bulin, Mamok, Mamokbulin. 2. Bulin, Oriental medical terminology, was used from Naegyeong's era to the Song Dynasty era and expressed as one of the symptoms in Jungpung(Stroke), Bi syndrome(Obstruction syndrom of Gi and Hyeol), Wi syndrome(Flaccid paralysis of the limbs), Hyeolbi(One of the Bi syndroms). But since the Keum Dynasty era, Mamok or Mamokbulin were more used than Bulin and that was refered as seperated disease. 3. Ma is paresthesia or dysthesia on the skin and the limbs, and the symtoms are not itchy, patients are felt like insect's crawling or bite. Mok is a stubborn symptom , the patients are felt like tree, which don't know pain and itching sensation. And therefore Ma is similar to positive phenomena and Mok is similar to negative phenomena in clinical aspect. 4. Mamok is GiHyeol(Gi is functional activities, Hyeol is blood) and Gyeonglak(Meridian system)'s disease. It's main causes are Giheo(Deficiency of Gi) and Hyeolhel(dificiency of Blood) and inducing tactors are Pung-Han-Seub(pathogenic wind-cold-dump) and Damtak(Phlegm-turbity), Eohyeol(Stagnated blood). 5. Mamok is induced from mononeuritis, multiple mononeuritis, polyneuropathy in the peripheral nervous lesions and also induced from cervical spondylosis, spinal tumour, multiple sclerosis, cerebrospinal vascular disease in central nervous systems.

Purpose: This study was done to examine the effects of oral care with essential oil in improving the oral health status of hospice patients with terminal cancer. Methods: The participants were 43 patients with terminal cancer admitted to K hospital in G city, Korea. Twenty-two patients were assigned to the experimental group and 21 to the control group. Participants in the experimental group received special mouth care with essential oil (application of essential oil mixture consisting of geranium, lavender, tea tree, and peppermint). The control group received special mouth care with 0.9% saline. The special mouth care was performed twice daily for one week in both groups. The scores for subjective oral comfortness, objective oral state, and numbers of colonizing Candida albicans were measured before and after the treatment. Results: The score for subjective oral comfortness and objective oral state were significantly higher in the experimental group compared to the control group. The numbers of colonizing Candida albicans significantly decreased in the experimental group compared to the control group. Conclusion: Oral care with essential oil could be an effective oral health nursing intervention for hospice patients with terminal cancer.

This paper describes the effect of a robot cognitive rehabilitation program on cognitive functions for the elderly with mild cognitive impairment, and compares it with traditional cognitive therapy programs. Three experiment groups including cognition therapy group, robot cognitive rehabilitation group, and hybrid group have been sampled and one comparative group has been organized for this research. 32 old people whose ages are between 61 and 88 with mild cognitive impairment participated in the programs with an admission of W care hospital. According to the program results, the cognitive therapy program alone had shown a positive effect on the attention function, and the robot cognitive rehabilitation program alone had a positive effect on the total intelligence and memory function. However, a simultaneous operation with both programs had shown a positive effect on the three intelligence areas such as total, basic, and management quotients as well as attention and memory functions as subsidiary factors. This paper has verified that the proposed robot cognitive rehabilitation program makes a positive effect on a cognitive function and plays a complementary role with traditional cognitive therapy programs.

A colonoscopy is important because it detects the presence of polyps in the colon that can lead to colon cancer. How often one needs to repeat a colonoscopy may depend on various factors. The main purpose of this study is to determine personalized surveillance interval of colonoscopy based on characteristics of patients including their clinical information. The clustering analysis using a partitioning around medoids algorithm was conducted on 625 patients who had a medical examination at Korea University Anam Hospital and found several subgroups of patients. For each cluster, we then performed survival analysis that provides the probability of having polyps according to the number of days until next visit. The results of survival analysis indicated that different survival distributions exist among different patients' groups. We believe that the procedure proposed in this study can provide the patients with personalized medical information about how often they need to repeat a colonoscopy.

Penetrating neck trauma by gunshot injury involving tracheobronchial tree is rare in Korea. Extensive tissue damage by cavitation, tissue fragmentation and shock wave transmission of high-velocity projectile along with associated organ injury renders high rate of mortality and morbidity. A 28 year old man in military service with gunshot wound in left cervical area presented initial symptoms of severe dyspnea and subcutaneous emphysema. Computed tomography of chest and cervical region as well as bronchoscopic evaluation was performed to confirm highly suspected injury to cervical trachea. Surgical exposure was established through a low collar incision; the damaged segment of 3.5 cm length including 2-4th tracheal rings was resected out and end-to-end anastomosis was performed. Bleeding from lacerated anterior jugular vein was controlled by ligation of both ends and a K2 bulllet was found upon inner border of body of first rib, medial to right carotid sheath and removed out. Cervical esophagus, carotid artery, internal jugular vein and recurrent laryngeal nerve were spared. Extubation was done on the first postoperative day and postoperative course until discharge on nineth postoperative day remained uneventful.

Purpose: The study aimed to investigate the factors associated with long hours of smartphone usage and to identify the characteristics of the high-risk group among female middle school students in South Korea. Methods: The study analyzed the data of 13,648 female middle school students using their own smartphone extracted from the 13th Youth Health Behavior Online Survey (2017). The factors related to using smartphones for a long time was analyzed by binomial logistic regression. The characteristics of the high-risk group was defined by a decision tree analysis. Results: The average hours spent on smartphone usage was 269.54 minutes per day. The significant factors associated with the long hours of smartphone usage were grade, living with parents, perceived household economic status, perceived academic achievement, stress, sadness and hopelessness, the main purpose of smartphone usage, drinking, body mass index, breakfast, and satisfaction with sleep quality. The subjects showing low academic performance and having breakfast four times a week or less were more likely to use their smartphone for a long time. Conclusion: Based on the results of the research, we need to establish intervention strategies focusing on the factors influencing long-time usage of smartphone. Particularly, the subjects who show poor academic performance and skip breakfast frequently should be considered as the high-risk group for spending long hours on smartphone usage.

Congenital web formations are extremely rare anomalies of the extrahepatic biliary tree. We herein report a case of common bile duct septum combined with multiple intrahepatic bile duct strictures in a 74-year-old female patient who was successfully treated with radiological intervention. The patient initially visited the hospital because of upper abdominal pain. Imaging studies revealed multifocal strictures with dilatation in both intra- and extrahepatic ducts; the final clinical diagnosis was congenital common bile duct web combined with multiple intrahepatic duct strictures. Surgical treatment was not indicated because multiple biliary strictures were untreatable, and the disease was clinically diagnosed as benign. The multiple strictures were extensively dilated twice through bilateral percutaneous transhepatic biliary drainage (PTBD) for 2 months. After 1 month of observation, PTBD catheters were successfully removed. The patient is doing well at 6 months after completion of the radiological intervention, with the maintenance of normal liver function. Congenital web of the bile duct is very rare, and its treatment may vary depending on the patterns of biliary stenosis. In cases where surgical intervention is not indicated for congenital web and its associated disease, radiological intervention with balloon dilatation can be a viable therapeutic option.
