The use of fluoride and other preventive methods caused a dramatic decline in dental caries and the need for restorative dentistry. In our modern society that places a high value on appearance, emphasis is now shifting towards esthetic dentistry which has experienced a high popularity with the development of bonding techniques and materials including porcelain and composite. To satisfy patients wanting whiter teeth and a better looking smile, there are many treatment options ranging from full crown coverage to conservative procedures such as bleaching. Whether bleaching should be combined with other esthetic procedures or used alone depends on the type of discoloration and the patient's willingness to accept the various treatment options. Therefore, in order to obtain a successful esthetic outcome, careful diagnosis and treatment planning followed by consultation with the patient is of utmost importance.

Dementia with Lewy bodies (DLB) is the second most common causes of dementia. It can exhibit a variety of clinical symptoms including cognitive decline, cognitive fluctuation, visual hallucinations, parkinsonism, REM sleep behavior disorder, hypersensitivity to neuroleptics and autonomic dysfunctions. Despite more well-known criteria for DLB, there are often misdiagnosis and inappropriate treatment. It gives a lot of clinical burden to the clinician as well as to patients and families. When reducing the misdiagnosis, the burden of all will be reduced. The special concern and solicitation are needed in order not to miss the diagnosis when the cardinal features of DLB may not be volunteered by patients and the caregivers. To control the symptoms, clinicians must find and reduce drugs that can have the negative effects on DLB symptoms. There is limited evidence about specific interventions but available data suggest cholinesterase inhibitors improve the cognitive and behavioral symptoms and menmantine slightly improves the global impression.

Nowadays new water supply projects have been on the decline as the water-power constructions have saturated, which means that the existing power equipment have slowly aged and they require more efforts to maintain the system performance. An effective asset management method of power equipment has become a great necessity from both economical and technical aspects. To be balanced, the asset management should look into all three parts: management, engineering, and information. The purpose of this paper is to study a Risk-Based Maintenance (RBM) matrix method through the deterioration evaluation algorithm for an efficient reliability assessment of oil-immersed power transformers by considering both asset management and technical evaluation. Make use of this result, the equipment will be decided to be replace or repair otherwise on service.

Epidemiological evidences and clinical as well as experimental observations have suggested a link between asthma and occupations. This relationship also involves other aspects like nonimmunologic exposures in the environment that can increase the chance of developing work related asthma and respiratory diseases. The purpose of this pamphlet is to supply information of work related diseases, which will give patients suffering with asthma, an intelligent understanding of their disease, and thus stimulate their interest so that they will cooperate more readily with their allergist. Recognizing the symptoms, causes, risk factors, diagnosis and treatment is an important part of managing occupational asthma and related diseases, so that it helps in decline of this rapidly increasing prevalence throughout the world.

Vascular dementia is a very frequent form of dementia. Debates over classification and diagnostic criteria, and controversy over identifiable treatment targets will continue until distinct pathophysiological mechanism of vascular dementia is found. Clinical diagnostic criteria are sufficiently strong to be useful for clinical trials, but need further refinement. Cognitive changes in vascular dementia are more variable than other disorders, and are dependent on the vascular pathology. Accurate diagnosis of vascular dementia is known to need the presence of reliable cerebrovascular disease on brain imaging. Although it seems obvious that cerebrovascular disease causes pathological damage and impaired cognition, it is very difficult to find the accurate contribution of cerebrovascular pathology to cognitive decline. Most studies have shown a small but significant benefit of cholinesterase inhibitors on cognition, the significance of this effect has been slight and benefits on global functioning, activities of daily living, and behaviour have not been consistently reported. Management of vascular dementia should focus on identifying and managing vascular risk factors.

Purpose: The physical deficits after stroke have been well documented, but there is little information on the sexual functions of stroke patients. This study examined the associations of the general characteristics with the poststroke changes in sexual functions. Methods: A survey was conducted on 200 stroke patients from November 2008 to February 2009. Among the 200 submitted questionnaires, 147 responded, and the results were analyzed by SPSS for windows version 14.0. Results: A majority of the stroke patients reported a marked decline in all the measured sexual functions, i.e., frequency of sexual intercourse, frequency of kissing and romantic touching, thinking about sex with interest or desire, ability to become sexually aroused and the overall level of sexual satisfaction. Significant differences were observed in age (p<0.01), years since diagnosis (p<0.05), and educational level (p<0.01). There were no significant gender differences (p>0.05). Conclusion: Decreased sexual function is a common problem after stroke. These finding demonstrate a need to develop sexual adaptation programs that can be effective in improving the sexual functions reported by stroke patients.

To examine the cognitive function of elderly, the study examined the performance of Korean normal elderly population whose age over 65 using neuropsychological instruments. It was predicted that the performance of the Korean population would be different from the U, S. mainly due to their difference in language, culture, and education. Korean elderly people from the Chungchung and Daejeon Metropolitan city(n=97) participated. Two age scores were developed: below 74 years and over 75 years. The effect of age, gender and education was examined, which yield significant age, gender and education effect. The score of DSF, DSB, TMTA, and TMTB are expected to be utilized for research purposes, such as basic, clinical, epidemiological studies, as well as practice purposes such as diagnosis and assessment of the progression of cognitive decline and dementia with MMSE-K.

Purpose: The purpose of this study is to propose a method to calculate the optimal preventive maintenance cycle of radar used in the aviation weapon system of ROKAF. Methods: A hybrid model is used to estimate the optimal preventive maintenance cycle in a system that can perform condition based predictive maintenance (CBPM) through continuous diagnosis. The failure data of the radars operating in the military were used to calculate the reliability. Results: According to the research results, the reliability threshold of the radar began to decrease after 5 flights, and decreased rapidly after 12 flights. Since the second check, costs have continued to decline. Conclusion: A method is proposed to determine the cycle of optimal preventive maintenance of radar within operational budget through modeling results between reliability limit and cost for radar. The results can be used to determine the optimal preventive maintenance cycle and frequency of various avionics equipment.

Purpose: To investigate the clinical characteristics and outcomes among infants and toddlers with failure to thrive (FTT). Methods: This retrospective study was done with 123 patients who had visited Pusan National University Children's Hospital during their first two years of life and had received an FTT diagnosis. We compared the clinical characteristics of the patients based on the causes of their FTT and their ages at the time of first hospital visit. We investigated triggering factors, feeding practices, and outcomes in 25 patients with nonorganic FTT (NOFTT). Results: Eighty cases (65.0%) were NOFTT. The gestational ages, birth weights, and weights at the first visits were significantly lower in patients with organic FTT (OFTT) (p<0.05). Infants who had first visited the clinic at age <6 months had the least z-score. The percentage of patients with severe weight decline was higher in OFTT than in NOFTT (60.0% vs. 17.3%). The z-scores at the follow-up visits were improved after treatment in both of the groups. Preceding infection was the most common triggering factor of NOFTT and persecutory feeding as abnormal behavior of caregiver was observed in 22 cases (88.0%). After treatment with feeding method modification, all patients with NOFTT showed normal growth. Conclusion: Weight decline is more severe in OFTT patients and in younger patients at the first visit. Infants with FTT can attain normal weight gain growth by treating organic diseases and supplying proper nutrition in OFTT, and by correcting abnormal dietary behavior of caregiver in NOFTT.

The harbor back area is not a planned space, but rather a space created by harbor space development. For this reason, the residential environment in the area behind the port has been very poor from the past to the present. Recently, the redevelopment has been increasing in accordance with the function of the port space. However, the development of the domestic port space is limited to the port space, and there is still little preparation for improvement of the residential environment in the port area. In this study, the degree of decline of the port area was diagnosed and analyzed for the purpose of deriving urban regeneration scenarios to improve the residential environment of port - backed areas. The urban regeneration factor to improve the livability of the port - backed area, which has been declining since then, was derived, and the scenarios in which each factor was applied were constructed.
