In the process of designing pareto optimal insurance contract, it is necessary to assume that insurance contract conditions are endogenous to build a model. The expected utility, the non-expected utility and the state-dependent utility function can be applied as a insurance decision making principle. The insurance costs may have the linear, convex, and concave ralationship with the indemnity schedule. However, the sunk cost and fixed cost must be recognized. The deductible which decides whether an insurance contract to be a full or partial insurance contract can exist in the forms of straight deductible or diminishing deductible. Indeciding the level of deductible, the types of the insurance and the risks to be insured should be the deciding factors. Especially for recall insurance, there is relatively high chance that the recalling company being bankrupt. Therefore, the possibility of bankrupcy should be the considering factor in deciding the policy limit. The existence of the incomplete market and uninsurable background risk should be understood as restricting conditions of the pareto-optimal insurance contract.

Benign symmetric lipomatosis, also known as Madelung's disease, Launois-Bensaude syndrome and multiple symmetric lipomatosis is a cutaneous condition characterized by extensive symmetric fat deposits in the neck, shoulders, and upper trunk. But symmetrical lipomatosis of the tongue is very rare and characterized by involvement exclusively of the tongue, invasiveness, and absence of encapsulation of the adipose tissue. A 75-year-old man presented with about a year history of painless tongue masses on both lateral border. Bilateral partial glossectomy was performed and subsequently was confirmed as symmetrical lipomatosis pathologically. We report this case with a review of the literatures.

The arguments exist that private health insurance(PHI) policy holders tend to use the health care services more than non-policy holders due to their little out-of-pocket spending, resulting in the adverse effects on the finances of National Health Insurance. This study aims to increase the objective understanding of the issue and to draw a direction of further research, by reviewing the articles, reports and statistics which examined the effects of purchasing PHI policies on health care utilization. Significant differences in healthcare utilization, except for the very partial increase of utilization in outpatient settings, have been not found. The similar trends of the results have existed in a few previous studies which tried to control the endogeneity of medical use and health insurance with latent variables which affect the decision on medical use and health insurance. However, we can not exclude the potential change of healthcare utilization patterns because the portion of the insured of indemnity PHI is becoming rapidly larger in the market. For further research, we should try to obtain the objective information of subjects' past medical history, health status, health related behavior, and income affecting purchase of PHI and utilization of healthcare services. And the efforts of controlling the endogeneity of medical use and health insurance with latent variables which affect the decision on medical use and health insurance, are very considerable.

Essential documents for proof of correctness of dental treatment covered by NHI are dental records and the receipt book. Summary of regal regulation about them is as follows 1. Chief complaints of patients, diagnosis, progress, and act of treatment, drugs and materials of treatment, doctor's sign, date and hour should be placed accurately on dental record 2. Dental clinic should collect patients sharing of the dental cost covered by NHI. 3. Dental clinic should keep the receipt as proof of purchase of dental drugs or materials.

Liver is an oragan which has various functions. For this functions in liver disease change variously, many methods of examination of them are invented. Each liver disease impairs these functions diversly rather than uniformly, thus it is possible to differentiate each disease by using various methods of testing it. Liver has high reproductive capacity and despite partial impairment of its function localized disease may not show any abnormality in liver function test due to compensation of remaining intact tissue of the liver. Thus the result of liver function test should be interpreted under adequate clinical investigation with other test, not depending on the liver function test only. This thesis deals with the composition, distribution in living body and clinical significance of liberating enzyme, GOT, GPT, and LDH which are included in serum enzyme that show abnormality in liver disease.

The study tests resilience and work ethics as mediators between charismatic leadership and affective commitment to change. Many organizations, such as banking, insurance companies, and financial institutions, face strong competition and consequently need to effect considerable change within the organization. Many variables have a significant impact on the success of organizational change, and people (resilience and work ethics) as well as change leaders are primary variables in this research. This study, using structural equation modeling, was conducted on a sample of 355 employees from banking and insurance companies. In this study, the inventory of affective commitment to change, the Conger-Kanungo charismatic leadership scale, resilience, and work ethic inventory was used. The results showed that resilience is a partial mediator between charismatic leadership and affective commitment to change. Meanwhile, work ethic was not a mediator between the two variables. The results showed that charismatic leadership can have a direct, positive, and significant impact on affective commitment to change without mediators, and that resilience can act as partial mediator. Furthermore, work ethic had a significant and positive effect on affective commitment to change through resilience. In other words, resilience is a full mediator for the impact of work ethic on affective commitment to change.

Underwriting refers to the process that the insurance company measures the potential risk of the future clients and decide whether insuring them with current premium. Although the traditional underwriting system used in Korean automobile insurance market is easy to understand, it is not based on a reliable statistical procedure. In this paper, we propose to apply the generalized additive model into construction of underwriting system, which is based on statistical analysis. We use automobile insurance data in Korea and apply our approach to the data. The results from the empirical analysis would be useful even for determining the significance of each variable in calculating automobile insurance premium.

Purpose. To investigate the differences in the frequency of post-fitting denture check-ups based on gender, age, insurance status, denture arch, and type among patients aged 65 and above. Methods. This research analyzed 988 patients from National Health Insurance Service Ilsan Hospital's Department of Prosthodontics, who had denture fittings over the last 10 years. Variables including gender, age, insurance status and type, denture arch, and denture type were assessed. Statistical analyses were performed at a 5% significance level. Results. The study incorporated 988 dentures, revealing a median of 3 check-ups post-fitting. Male patients significantly had more visits than females (P = .017), and those with full metal dentures visited significantly more than those with partial dentures (P = .005). Other variables were not significantly influential on the post-fitting check-up frequency. Conclusion. Within this study's confines, an increase in denture adjustment sessions was observed for male patients and those with full metal dentures.

Lamotrigine is a newer anti-epileptic drug for adjunctive treatment of refractory epilepsy, partial seizures, generalized tonic-clonic seizures, and bipolar disorder. Lamotrigine overdose causes serious central nervous and cardiovascular problems, but reports are uncommon. Few lamotrigine overdoses have been described because anti-epileptic drug use is limited and usually used with combination of other anti-epileptic drugs. In addition, most patients visit emergency departments with multi-drug overdoses, so few cases of lamotrigine poisoning alone exist. We had a female patient visit our emergency department a couple of hours after a lamotrigine overdose treated with intravenous hydration and urine alkalization by NaHCO3. She recovered successfully without any evidence of renal injury. However, she developed profound rhabdomyolysis, a previously unreported complication of this medication. We suggest that serial creatine kinase levels should be measured after lamotrigine poisoning.
