Fiberglass may be a pulmonary toxin and carcinogen because it imitates asbestos, as do other man-made mineral fibers. A 5-months-old Jind dog was accidentally exposed to fiberglass extensively for 3 months in a site of apartment construction. Canine acute clinical pneumoconiosis caused by fiberglass was diagnosed by history, ezamination of environment, physical examination, and chest x-ray check of patient. The main signs were anorexia, dyspnea, increased irregular opacities and air trapping in lung field of chest x-ray films. Because the fiverglass which is used for several purpose are dangerous for health of animal and human. fiberglass dust must be controlled to minimize the adverse effects of fiberglass in the environment.

A lot of data, particularly in the medical field, contain variables that have a measurement error such as blood pressure and body mass index. On the other hand, recently smoothing methods are often used to solve a complex scientific problem. In this paper, we study a Bayesian curve-fitting under functional measurement error model. Especially, we extend our previous model by incorporating covariates free of measurement error. In this paper, we consider penalized splines for non-linear pattern. We employ a hierarchical Bayesian framework based on Markov Chain Monte Carlo methodology for fitting the model and estimating parameters. For application we use the data from the fifth wave (2012) of the Korea National Health and Nutrition Examination Survey data, a national population-based data. To examine the convergence of MCMC sampling, potential scale reduction factors are used and we also confirm a model selection criteria to check the performance.

The fundamental goal of dental treatment is rehabilitation of oral health thus various dental treatment are done. Most of the dental procedures are not life threatening but patients who are medically compromised are exceptional. Fortunately systemic disease can be easily diagnosed by medical insurance(medicare) or annual medical check examination in Korea. Diseases which were fatal at the past are successfully treated nowadays and consequently the population of the elder increases. As the population of elder increases, patients who need medical care as well as dental patient with compromised medical condition increases. It is essential to find out if the patient has any systemic disease. Consultant to the appropriated physician of medically compromised patients? is demanded and also for a successful dental treatment, deep knowledge of the systemic disease is necessary.

Rhinoliths are foreign bodies composed of mineralised deposits in the nasal cavity that are rarely encountered in routine dental practice. The current report presents a case of a 77-year-old female patient who visited a dental treatment centre for a routine dental check-up and prophylaxis. On the clinical examination, the patient did not report any breathing difficulty, nasal obstruction, or any form of discharge. Panoramic radiography showed a horizontally magnified radiopaque structure in the right nasal fossa region. Cone-beam computed tomography (CBCT) revealed a hyperdense entity with a laminated presentation in the right nasal fossa. The hyperdense entity was diagnosed as a rhinolith based on the radiographic findings. Although the patient was asymptomatic, a referral was made to an ear, nose, and throat surgeon for a further evaluation. This report highlights the importance of CBCT imaging in the diagnosis of soft-tissue calcifications.

An eight-year-old, 28-kg male bull terrier who showed signs of lethargy and cough was referred for further evaluation of congestive heart failure. On presentation, physical examination revealed a systolic murmur at the left apex of the heart. Moreover, chest radiograph evaluation confirmed the mild alveolar and interstitial patterns in the caudal lung lobes and a grossly enlarged left atrium and left ventricle. Electrocardiography showed atrial fibrillation with a wide QRS complex, and transthoracic echocardiography revealed marked enlargement of the left atrium with abnormal morphology of the mitral valve. The thickened, hammer-like appearance and abnormal diastolic motion of the mitral valve leaflets were characterized by decreased leaflet separation and doming of the valve. The diagnosis was mitral stenosis with congestive heart failure and atrial fibrillation. The owner declined interventional valvuloplasty. Medical treatment included furosemide, pimobendan and diltiazem. Regular health check-ups have shown that vitality and clinical signs have improved considerably, and the dog have remained stable for 6 months after the presentation.

The major findings of this investigation on radiographic works in 125 medical institutions around Seoul and Kyung-Ki area, from March 1983 to February 1984, are summarized as follows. 1. The number of references provided on radiographic techniques were 3 to 5 in general hospitals (52.1%), in hospitals (58.5%), and clinics (44.5%), and only the 10.4% of general hospitals had 11 or more. 2. The relatively high percentages of 75.0% of general hospitals and 68.3% of hospitals have established the standardized radiographic methods for regions examined, but most clinics (61.1%) have not. 3. As a log system for the radiographic request, the method of "routine study, or all the x-ray examinations are marked as 0 on a printed form" was most commonly used by general hospitals (62.5%) and hospitals (51.2%), and "the doctors employ their own methods" in most clinics (44.6%). 4. In the 85.4% of general hospitals, the 68.3% of hospitals and the 38.9% of clinics, the data such as diagnosis, clinic history, purpose of x-ray examination were recorded on a radiographic request at all times, or at least in part. 5. On a scale of hardness and easiness of order of doctors, the greatest response was "fairly easy to understand", and the 37.5% of general hospitals responded as "sometimes hard". 6. In determining the standards for radiographic factors, the general hospitals (62.5%) and hospitals (65.9%) adapted mostly "a departmental check list", and the clinics (61.1%) used mainly "a personal decision". 7. In using the immobilizing devices, angligner, and radiographic accessories, the Percentages were high in general hospitals and hospitals on the one hand, and were low in clinics on the other. 8. A consideration with regard to the devices for an improvement of examination of the same patients was totally ignored by the 50.0% of clinics, the 26.8% of hospitals and the 20.8% of general hospitals. 9. The causes of re-examination were due largely to patients (33.6%), and followed proportionately by incorrect exposure (22.8%), errors in positioning (22.0%), film processing faults (9.2%), conditions of x-ray equipments (8.8%), and quality of x-ray films (3.6%). 10. The conference on radiography was conducted regularly or irregularly by the 87.5% of general hospitals, the 56.1% of hospitals, and the 27.7% of clinics, and the meeting was proceeded only by radiologic technologists.

BACKGROUND/OBJECTIVES: The elderly are reported to have a high prevalence of nutritional anemia when they have lower intakes of nutrients or chronic diseases. This study was conducted to compare nutritional status according to nutritional anemia and to determine associations between nutritional anemia and chronic diseases in Korean elderly. SUBJECTS/METHODS: This study utilized data on 3,258 elderly aged ${\geq}65$ years gathered during the $6^{th}$ Korea National Health and Nutrition Examination Survey 2013-2015. Subjects were divided into nutritional anemia (NA) group (n = 415) and non-NA group (n = 2,843) by hemoglobin concentration. Nutrient intakes were assessed using dietary intake data obtained using the 24-hour recall method. The odds ratios (ORs) for nutritional anemia by chronic diseases were determined. Statistical analysis was performed using SPSS Ver. 23.0. RESULTS: Of 3,258 subjects, 12.7% had nutritional anemia. Intakes of potatoes, pulses, and mushrooms by males and potatoes, fruits, meats, eggs, and seafood by females were significantly lower in NA group than in non-NA group. The proportion of the subjects whose intakes of protein, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin, and iron less than estimated average requirement (EAR) were significantly higher in NA group compared to non-NA group. After adjusting for age, the number of family members, energy intake, and alcohol drinking, ORs for nutritional anemia in the subjects with diabetes and myocardial infarction or angina pectoris were significantly higher by 1.74 times and 1.59 times as compared to the subjects without those diseases, respectively. However, ORs for nutritional anemia in the subjects with obesity, abdominal obesity, and hypertriglyceridemia were significantly lower by 0.64 times, 0.60 times, and 0.59 times as compared to the subjects without those diseases, respectively. CONCLUSIONS: The results of this study suggested that nutritional management should be done to enable the Korean elderly to consume foods with high hematopoietic nutrients density to prevent nutritional anemia. Korean elderly need to make regular efforts to check for nutritional anemia.

1,281 male subjects who had been examined more than 3 times for regular check-up in one human dock center of the university hospital were studied between 1990-1995, to evaluate the effect of health counselling with life style and $\gamma-GTP$ value between 1054 normal group without intervention and 227 abnormal group with intervention, ages from 30 to 69 years old. Total mean value of $\gamma-GTP$ was $45.7{\pm}40.7$ unit with highest $\gamma-GTP$ value in age group 50-59 on initial examination. Total abnormal rate was 17.7% with the highest abnormal rate of 18.6% in age group 50-59. Initially, the value of $\gamma-GTP$ was significantly different according to the degree of alcohol intake, relative weight and smoking in normal group(p<0.01) not in abnormal group. In conclusion, the value of $\gamma-GTP$ were significantly increasing in normal group without intervention and significantly decreasing in abnormal group with intervention(p<0.05), which suggests the effect of health counselling, such as the recommendation to change the health behaviour.
