Objectives : The purpose of this study was to analyze and investigate the effecting factors on the actual condition of dental clinic use of the out patient. Methods : In oder to achieve this purpose, A survey for 302 patients in 6 participating dental clinics located in Daejeon metropolitan city from May 01 to May 30, 2010. The result of this study was as follows. Results : 1. The duration of dental clinic use was reflected in 36.1% of the under 1 year, 34.1% of over 2 years, and 29.8% of over 1 ~ under 2 years in order. Especially, the higher the duration of over 2 years the higher the age was, on married group had a significance. 2. The type of medical examination for samples was 27.6% of periodontal, 26.5% of conservative, 17.2% of prosthodontics, 10.9% of implant, and 7.9% of preventive in order. Especially, the male group the more the prosthodontics, implant had a significance. the higher the monthly income, on married group, the more the periodontal, prosthodontics and implant had a significance. 3. The motive of dental clinic selection was 38.4% of acquaintances' inducement, 33.4% of the superb treatment, 15.6% of easy convenience, and 7.0% of friendliness staff in order. Especially, male group the more the easy convenience, superb treatment, friendliness staff had a significance. 4. The mean of transportation in order to visit a dental clinic was 38.7% of public transportation, 37.5% of the own car, 23.8% of others in order. Especially, there was a highly significant difference on the public transportation in female, the lower education level, lower monthly income, and medical protection group. 5. The duration of time required of dental clinic reflected in 80.1% of the under 30 minute, 16.3% of over 30 minute~under 1 hour, and 3.6% of over 1 hour in order. Especially, the higher the treatment satisfaction, the dissatisfaction the higher the duration of time required under 30 minute had a significance. Conclusions : These results indicate that as medical services upgrade and get more varied, the expectation of medical quality also increases. It is thus considered that the revitalization of this hospital's management strategy can be achieved by providing highly developed medical services, and, more importantly, by better understanding the actual conditions of dental clinic use by the patients themselves.

Our medical care system is trying to diversify in order to meet the client's needs, and to adjust to a medical environment which is changing very rapidly. Because current nursing theory and practice focus on holistic care, health care management, education, and research, contrary to the traditional emphasis on only assisting a physician, more autonomy and specialization for the implementation of nursing are required. Considering these trends and actual needs, the category of clinical nurse specialist should be established as soon as possible. In order to develop strategies for implementing this new professional specialty, the authors conducted a field survey and literature review of the current system in Korea. As a result, various obstacles and constraints were discovered as follows : 1) There are few accredited educational programs for the training of CNS's. 2) Several hospitals already have staff designated as clinical nurse specialist (CNS) even though the term CNS is not yet standardized or adopted in nationwide. 3) The role of the CNS is not clearly understood by the medical societies, or even nursing societies. A nurse who works in specific nursing areas such as central supply, kidney dialysis, intensive care, coronary care, etc. for a long time, considers herself /himself a CNS. Based upon the above findings, the following alternatives are recommended. 1) The role of the CNS should be defined according to specified functions and authority : professional autonomy ; counselling and educating patients and their familes, nurses, and even other medical personnel ; research on improvement of nursing ; and management of the nursing environment including medical resources, information, and cases. 2) the qualification of CNS should be attained only by a nurse who has an RN license and clinical experience of more than 3 years in a specific nursing field: passes a qualifying examination; and contributes to the professional development of peers, colleagues, and others. A master's degree should only be optional, because of the insufficient of graduate programs which are well designed for the CNS. 3) The CNS should initially be a head nurse rather than line staff in order to deal with as wide an experience base as possible. 4) The nursing specialty could be divided into two areas such as a clinical field and a community field. The clinical field could then be categorized by the Styles' classification such as diseases and pathogenics, systems, ages, acuity, skills/techniques, and function/role ; the community field could be classified according to work site.

BACKGROUND : The purpose of this study was to investigate the new effective oriental medical treatments in pediatric diseases and its clinical applicability. METHOD : The study was composed of 1725 new patients who had been treated at the pediatric unit in the Dongguk Bun-Dang Oriental Medicine Hospital for 1 year, from 1 January 1997 to 31 December 1997, and had ages between 0 and 18 years. The chief complaint was mainly categorized by oral examination on patients and their care-givers. RESULT 1. The ratio of male to female was 1.35:1 and the number of each age group and its percentage distribution was 228 patients (13.2%) for the age group between 0 and 1 year, 746 patients (43.2%) between 2 and 6 years, and 751 patients (43.6%) for the age group over 7 years. 2. The chief complaint of the new outpatients was weakness, asthma, common cold, sinustis, skeletal disease, atopic dermatitis, stomach-ache, short stature, diarrhea, nasal blooding, night terror, allergic rhinitis, gastric disorder, enuresis, dermatitis, strabismus in the order of majority.3. The number of patients and its percentage for the most three complaints was 494 patients (28.6%) for weakness, 647 patients (37.4%) for respiratory disease, 144 patients (8.3%) for digestive disease. 4. The digestive disease tended to increase in summer, and appeared mostly in the age group between 0 and 2 years. The respiratory disease increased In inter-season and winter, but decreased significantly in summer. The age group between 1 and 5 years was the largest group of respiratory disease. CONCLUSION 1. The chief complaint in pediatric diseases that needed an oriental medical treatment was mainly the disease that tends to take long time and the weakness, and appeared frequently in digestive and respiratory diseases. 2. The oriental medical treatment was still preferred as a way to improve the weakness by patients, rather than a way to overcome their disease. In particular, the study shows that the oriental medical treatment should be emphasized in terms of preventing the disease. 3. The new diseases, which were developed with the change of human life and environment, (atopic dermatitis, enuresis, short stature, obesity, dysthymic disorder, strabismus), should be investigated as a new field of oriental medical treatment.

The aim of this study was to evaluate anteroposterior oblique(RPO, LPO) and posteroanterior oblique(LAO, RAO) projections of the cervical spine, at various kVp and mA s increments, in order to compare thyroid surface dose. Using Rando phantom, dosimeter was attached to the Cervical spine 4~5 to measure the surface dose in the same thyroid position. As a result, the surface dose was $595.08{\pm}215.01{\mu}Gy$ for anteroposterior oblique(RPO, LPO) projections and $64.21{\pm}33.49{\mu}Gy$ for posteroanterior oblique(LAO, RAO) projections by changing kVp increment. The surface dose was $445.20{\pm}230.90{\mu}Gy$ for anteroposterior oblique(RPO, LPO) projections and $44.51{\pm}22.77{\mu}Gy$ for posteroanterior oblique(LAO, RAO) projections by changing mAs increment. The posteroanterior oblique method could reduce about 90% the surface dose than the anteroposterior oblique method. There were statistically significant differences among the examinations(p<0.001). Change the direction of position to reduce the surface dose at oblique projection of cervical spine. Therefore, we consider posteroanterior oblique projections than anteroposterior oblique projections of cervical spine examination in other to reduce patient surface dose.

background: The prognosis after an aortic valve replacment can be affected significantly by the transprosthetic pressure gradient which is determined mainly by the size of the patients body and the prosthesis used. We analyzed the hemodynamic feature of two relatively new prosthese the ATS and the evensized Medtronic-Hall(M-H) valves by measuring the transprosthetic pressure gradient in the cases where small sizes (23mm or smaller) were used. Material and method: There were 94 patients who received whom aortic valve replacement with prosthesis smaller than 23 mm from October 1994 to June 1998. In these patients the transprosthetic pressure gradient clalculated from the pressure half time during postoperative Dopper echocardiographic examination was compared between the prostheses of different sizes. The body surface area of each patient was also taken into consideration. result: The mean pressure gradient and body surface area in each group were 21.7$\pm$10.2 mmHg and 1.52$\pm$0.14m2 in ATS 19mm 11.4$\pm$6.5 mmHg and 1,57$\pm$0.20m2 in M-H 20mm 15.2$\pm$6.3 mmHg and 1.54$\pm$0.13m2 in ATS 21mm 9.3$\pm$2.5 mmHg and 1.63 $\pm$0.14m2 in M-H 22 mm and 12.9$\pm$5.3 mmHg and 1.69$\pm$0.13m2 in ATS 23mm. Conclusion: The 19mm ATS prosthesis showed significant trasprosthetic pressure gradient which is similar to the values previously reported with other bileaflet prosthesesm Close follow-up was needed in terms of exercise capacity and change in left ventiricular geometry. In patients with small aortic valve annulus the 20mm M-H valve is recomendable as an alternative to 19mm bileaflet valves because it has less pressure gradient with similar outer diameter.

Background: This study was designed to determine etiologic factors for iatrogenic pneumothorax in an era of in-creased use of invasive procedures and to evaluate its impact on morbidity. Material and Method: Subjects were 112 patients (65 men and 47 women ranging in age from 20 to 90 years) who were diagnosed with an iatrogenic pneumothorax between January 2005 and December 2008. We reviewed medical records retrospectively. Result: The leading causes of iatrogenic pneumothorax were percutaneous needle aspiration (50), central venous catheterization (29), acupuncture (14), thoracentesis (8) and positive pressure ventilation (7). The majority of the patients (60 of 114) were treated with chest tubes. The mean duration of hospital treatment was 5.8 $({\pm}4.0)$ days. Hospitalization was prolonged in 24 patients (21.1%). No patient died from iatrogenic pneumothorax. Conclusion: In our study, the most common cause of Iatrogenic pneumothorax was percutaneous needle aspiration. The mortality and morbidity from iatrogenic pneumothorax is not significant. The recognition of pneumothorax, depends on careful examination after completion of an invasive procedure, and should be followed by prompt and definitive therapy.

Chemotherapy-induced nausea and vomiting (CINV) is a debilitating side effect related to activation of substance P (SP). SP activation can result from dysregulation of the gut-brain axis, and also from activation of protein kinase A signaling (PKA) signaling. In this study, we connected these factors in an attempt to unveil the mechanisms underlying CINV and develop new therapeutic strategies. Female rats were injected with cisplatin (Cis) to induce pica. Fecal samples were collected before/after injection, and subjected to lipid metabolomics analysis. In another portion of pica rats, the PKA inhibitor KT5720 was applied to investigate the involvement of PKA signaling in CINV, while fecal microbiota transplantation (FMT) was implemented to verify the therapeutic effect of the lipid metabolite 14(15)-EpETE. Pica symptoms were recorded, followed by ileal histological examination. The targeting relationship between 14(15)-EpETE and glucagon was determined by bioinformatics. SP and glucagon/PKA signaling in rat ileum, serum, and/or brain substantia nigra were detected by immunohistochemistry, enzyme-linked immunosorbent assay, and/or western blot. The results showed a significantly lower level of 14(15)-EpETE in rat feces after Cis injection. KT5720 treatment alleviated Cis-induced pica symptoms, ileal injury, SP content increase in the ileum, serum, and brain substantia nigra, and ileal PKA activation in rats. The ileal level of glucagon was elevated by Cis in rats. FMT exerted an effect similar to that of KT5720 treatment, relieving the Cis-induced changes, including ileal glucagon/PKA activation in rats. Our findings demonstrate that FMT restores 14(15)-EpETE production, which inhibits SP release by targeting GCG/PKA signaling, ultimately mitigating CINV.

Purpose : The diagnosis of the causes of residual pain after ankle fractures and the treatment is not simple. The authors analyzed the clinical results of the patients with residual pain after ankle fracture fur whom ankle arthroscopy was undertaken, for the purpose of evaluating the efficacy of arthroscopic diagnosis and treatment. Materials and Methods : From January 1997 to June 1998, ankle arthroscopy was done for the seventeen patients suffering from residual ankle pain and limitation of motion after ankle fracture. Their symptoms were not improved despite conservative treatment. There were sixteen men and one woman, and their mean age was 37.4 years. Result : Radiological examination revealed loose bodies in two patients, and osteophytes at the anterior rim of the tibia in fourteen patients. By the classification of osteoarthritic change, three ankles were assigned to grade 0, eight to grade I, six to grade II, and none to grade III. On arthroscopic examination, soft tissue impingement was found In thirteen cases, loose bodies in five cases, and osteochondral lesions in four cases. For arthroscopic treatments, removal of soft tissue, abrasion of osteophytes, cartilage shaving and removal of loose bodies were done. Clinical results were evaluated using Evanski and Waugh score. Preoperative overall score of 58.7 points jumped to 74.6 points after the operation, and in fourteen patients$(82\%)$ the symptoms were improved. Conclusion : Ankle arthroscopy is considered to be a very useful diagnostic and treatment method fer the patients with residual complaints after ankle fracture.

Introduction: In Oriental medicine, the status of tongue is the important indicator to diagnose one's health, because it represents physiological and clinicopathological changes of inner parts of the body. The method of tongue diagnosis is not only convenient but also non-invasive, so tongue diagnosis is most widely used in Oriental medicine. By the way, since tongue diagnosis is affected by examination circumstances a lot, its performance depends on a light source, degrees of an angle, a medical doctor's condition etc. Therefore, it is not easy to make an objective and standardized tongue diagnosis. In order to solve this problem, in this study, we tried to design a discriminant function for thick and thin coating with color vectors of preprocessed image. Method: 52 subjects, who were diagnosed as white-coated tongue, were involved. Among them, 45 subjects diagnosed as thin coating and 7 subjects diagnosed as thick coating by oriental medical doctors, and then their tongue images were obtained from a digital tongue diagnosis system. Using those acquired tongue images, we implemented two steps: Preprocessing and image analyzing. The preprocessing part of this method includes histogram equalization and histogram stretching at each color component, especially, intensity and saturation. It makes the difference between tongue substance and tongue coating was more visible, so that we can separate tongue coating easily. Next part, we analyzed the characteristic of color values and found the threshold to divide tongue area into coating area. Then, from tongue coating image, it is possible to extract the variables that were important to classify thick and thin coating. Result : By statistical analysis, two significant vectors, associated with G, were found, which were able to describe the difference between thick and thin coating very well. Using these two variables, we designed the discriminant function for coating classification and examined its performance. As a result, the overall accuracy of thick and thin coating classification was 92.3%. Discussion : From the result, we can expect that the discriminant function is applicable to other coatings in a similar way. Also, it can be used to make an objective and standardized diagnosis.

Purpose The importance of quality control by the error to a minimum, which for the purpose of enhancing the reliability of the examination is not be emphasized excess. Currently, most nuclear medicine laboratory are conducting the internal and external quality control, and they are applying the Levey-Jennings or Westgard Multi-Rules by using the commercialized quality control materials. The reliability of the nuclear medicine blood test which affects the diagnosis of patients and the treatment policy is being secured through this quality control activity. Therefore, researchers will evaluate the utility of the statistic quality control using the population distribution of the nuclear medicine blood test conducted targeting the checkup examinees by the additional technique of the reliability improvement. Materials and Methods A statistic analysis was performed about 12 items of the nuclear medicine blood test targeting 41,341 peoples who used the health screening and promotion center in Asan Medical Center from January, 2014 to December, 2014. The results of 12 items of the nuclear medicine blood test was divided into the monthly percentage of three groups: within reference values, over reference, and under reference to analyze the average value of the population distribution, standard deviation, and standard deviation index (SDI). Results The standard deviation of the population distribution mostly showed a result within ${\pm}2SD$ in all groups. However, When the standard deviation of the population distribution represented a result over ${\pm}2SD$, it was confirmed SDI was showing a result of SDI > -2 or SDI > 2. As a result of analyzing the population distribution of 12 items(AFP, CEA, CA19-9, CA125, PSA, TSH, FT4, Anti-Tg-Ab, Anti-TPO-Ab, Calcitonin, 25-OH-VitD3, Insulin) of the nuclear medicine blood part basic test, when SDI of the monthly percentage which deviated from the reference values was over ${\pm}2.0$, CA19-9 September was 2.2, Anti-Tg-Ab may was 2.2, Insulin January was 2.3, Insulin March was 2.4. It was confirmed these cases were attributed to the abnormality of the test reagent (maximum combination rate of isotope reagent declined) and the decline of the test response time. Conclusion The population distribution includes the entire attribute which becomes the study object. It is expected the statistic quality management using the population distribution which was conducted targeting the checkup examinees by dividing into three groups: within reference values, over reference, and under reference by means of this characteristics will be able to play a role of complementing the internal quality control program which is being carried out in the laboratory.
