It has been approximately 40 years since $Br{{\aa}}nemark$ first introduced osseo-integration for implants in the early 1960s. Unlike crown and bridge or denture treatment, implant treatment helps preserve existing bone and improve masticatory functions. Thus, the awareness of implant treatment has grown rapidly among dentists and patients alike in Korea, as it becomes a widely accepted treatment. The following results on patients type and implant distribution were compiled from 1814 implant cases of 640 patients treated at the periodontal dept. of Y University Hospital during 1992 to 2001. 1. There are no dissimilarities between men and women, with patients in their 40,50s accounting for 49% of patients and 56% of implant treatments; the largest share of patients and implant treatments. 2. Mn. posterior area accounted for 59% of implant treatments followed by Mx. posterior area(21%), Mx anterior area(l4%) and Mn anterior area 2%. 3. Partial edentulous patients treated by single crown and bridge-type prosthesis accounted for 98% and fully edentulous patient accounted for the remaining 2% 4. The major cause of tooth loss is periodontal disease, followed by dental caries, trauma and congenital missing. Compared to women, men are more likely to suffer from tooth loss due to periodontal disease. Also, older people are more likely to suffer from tooth loss due to periodontal disease rather than dental caries. 5. The distribution of bone quality for maxillae was 52% for type III, followed by 23% for type II, 20% for type IV and 0% for type I. As for mandible, the distribution was 52% for type II, followed by 37% for type III, 7% for type IV and 4% for type I. 6. The distribution of bone quantity for maxillae was 49% for type C, followed by 34% for type B, 14% for type D, 3% for type A, and 0% for type E. As for mandible, the distribution was 52% for type B, followed by 35% for type C, 6% for type D, 3% for type A and 0% for type E. 7. The majority of implants were those of 10-14mm in length (80%) and regular diameter in width (79%). The results provided us with basic data on patient type, implant distribution, bone condition, etc. We wish that our results coupled with other research data helps assist in the further study for better implant success/survival rates, etc.

An in-line wet etch/cleaning system was established for the research and development in wet etch process. The system was equipped with a reverse moving system for the reduction in the size of the in-line wet etch/cleaning system and it was possible for the glass substrate to be moved back and forth and alternated in a wet etch bath. For the comparison of the effect of the normal motion and that of the alternating motion on the in-line wet etch process, indium tin oxide(ITO) pattern was obtained through both wet etch process conditions. The results showed that the alternating motion is not inferior to the normal motion in etch rate and in etch uniformity. It is concluded that the alternating motion is possible to be applied to the in-line etch process.

Lateral eyebrow mass with primary skull lesion are rare in pediatric population. Although epidermoid cyst and dermoid cyst are the most commonly encountered skull lesions in pediatric population, Langerhans cell histiocytosis (LCH) is rarely reported. We report a case of LCH arising from the lateral eyebrow with osteolytic lesion involving the frontal bone. A 5-year-old boy was presented with a hard, fixed mass in his lateral eyebrow. Contrast magnetic resonance imaging revealed inhomogeneous enhancement of the mass with direct invasion of the frontal bone and adjacent dura mater. Under general anesthesia, linear incision at the lateral eyebrow region was made. Intraoperative evaluation revealed hard, fixed and well-defined soft tissue mass. The final extirpated mass was $2.5{\times}2.4cm$ in size, and was accompanied by a $1{\times}1cm$ sized defect on the frontal bone with intact dura mater. The surgical wound was closed primarily by a layer-by-layer fashion. Histologic examination was later performed for definite diagnosis. The histologic examination revealed abnormal proliferation of Langerhans cell with granuloma formation. Radionuclide bone scan and positron emission tomography was taken and revealed free of multi-organ involvement. At 3 months after surgery, natural looking contour at the lateral eyebrow region was observed with no tumor recurrence. Differential diagnosis of the hard and fixed mass at the lateral eyebrow region affecting the primary skull lesion from pediatric population includes epidermoid cyst, dermoid cyst and LCH. Generally, brief physical examination with plain X-ray view can be performed for clinical evaluation, but for a definite diagnosis, contrast MRI may be helpful.

계약상 의무위반과 구제법리

홍성재(Sung-Jae Hong) 한국재산법학회 2010 재산법연구 Vol.27 No.2

A party in a contract should perform the duty of the contract. The duty of contract consists of main performance obligation, collateral obligation and protective obligation. Main performance obligation corresponds to the duty which determines the substance and nature of a contract. In case when main performance obligation is infringed, it can enforce the performance of the contract, and the compensation for the breach of contract and cancellation of the contract are admitted. And collateral obligation is the duty for the purpose of protecting benefits of a contract. Although there is an argument whether to classify performance obligation into main performance obligation and collateral obligation or not, these are distinguished from each other in this study. That is because unlike infringing main performance obligation, violating collateral obligation is not allowed to enforce to perform or cancel the contract. It is only allowed to claim damage reparations. Also, a duty of safety is not based on the party’s will, but on forcd obligation in accordance with good faith and fair dealing. And unlike the collateral obligation, the duty of safety aims at protecting another party’s integrity or existing interest. But, in case of violating the duty of safety, it is not allowed to force the performance of duty, but is only allowed to claim for damage reparations. This kind of duty of safety holds good from the process after the extinguishment of the contract. Also, a third party beside the party involved in the contract can the person concerned of protective obligation. However, even though these have the same substance, a duty to give attention to and protective obligation should be distinguished. The reason is that among the duties to give attention to, there is a case which belongs to performance obligation that entails a certain legal relation like labor contracts. Also, even if both of them accompany legal benefits, the transit security duty of tort law and the protective obligation of contract law should be distinguished. The party who is damaged by violating duty of safety, rather than the party who is damaged by infringing transit security duty, is able to receive remedy for the right according to legal principles of contract liability, which is superior in aspects of responsibility for proof or extinctive rescription. In the meantime, the obligation of contract as above belongs to the substance of a obligation, so violating it is applicable to non-fulfillment. Then it takes different remedies according to the case of non-fulfillment; delay in performance, non-impossibility and imperfect performance. Also it takes different requirement according to the ways of remedy for the right; forcing the performance of obligation, claiming compensation for the damage or canceling a contract. Especially, in case that excessive damage beyond benefits of a contract is incurred because of non-impossibility and imperfect performance, there is no room for claiming forced performance or canceling a contract. And unlike forced performance, in order to claim compensation for the damage, the damage due to the breach of contract should be incurred because of the reason that obligor can be blamed of. Besides, in case of canceling the contract, obligor should be responsible forthat. However, in occasion of delay in performance, it is allowed to cancel the contract only when it doesn't perform the obligation of contract within a grace period. Of course, in case that obligation of a onerous contract is imperfectly performed, damaged party can claim responsibility about warranties liability of non-negligence. of negotiating a contract, through the process of realization of the contract, obligor should be responsible for that.

도급계약에서의 계약이행보증금의 성질에 관한 판례의 검토

홍성재(Hong, Sung Jae) 전북대학교 법학연구소 2015 法學硏究 Vol.43 No.-

이 글에서는 다양한 목적을 가지고 행해지는 위약금 약정의 실태를 반영하기 위해서는 위약금 개념을 보다 유연하게 해석할 필요가 있는 것으로 보았다. 즉, 위약금에는 그 감액이 인정되는 손해배상액의 예정과 그것이 인정되지 않는 위약벌의 성질을 가진 것이 있음은 물론이고, 그 밖에 특수한 손해배상액의 예정이라든가 손해의 담보의 성질을 가진 위약금, 또는 손해배상액의 예정과 위약벌을 겸유하는 위약금의 유형이 있을 수 있다고 보았다. 물론 민법은 특별한 사정이 없는 한 위약금을 손해배상액의 예정으로 추정한다. 이러한 입장은 도급계약의 경우, 계약이행보증금에 관한 판례의 검토를 통해서 확인 되었다. 첫째, 귀속약정이 없는 계약이행보증금은 계약금의 성질을 가진다. 따라서 그 보증금만 지급한 상태에서는 민법 제565조에 따라 도급계약을 해제할 수 있다. 그리고 이 경우 계약이행보증금은 위약금으로 하기로 하는 특약이 없는 한 손해담보 내지 손해보증금의 성질을 겸유할 수 있다. 이 경우 도급인은 손해의 발생과 범위를 입증하여야 비로소 손해배상을 받을 수 있다. 둘째, 도급계약에서 그에 관한 귀속약정만 있는 계약이행보증금은 손해배상액의 예정의 성질을 가진다. 판례는 도급계약에서 계약이행보증금과 아울러 지체상금의 약정을 한 경우에도 그 보증금은 손해배상액의 예정의 성질을 가진 것으로 보고 있다. 이 경우 도급인은 초과손해의 배상을 받을 수는 없고, 오히려 법원은 계약이행보증금이 부당히 과다한 경우에는 그 보증금을 감액할 수 있다. 셋째, 계약이행보증금이 계약의 이행을 압박하고 위약하였을 때에는 사적인 제재를 가하는 것을 목적으로 교부된 경우에는 그것은 위약벌의 성질을 가진다. 즉, 도급계약에서 계약이행보증금의 귀속약정 외에 별도로 실손해 전부에 대한 배상을 인정하는 경우에 그렇다. 이 경우 법원은 계약이행보증금을 감액할 수 없고, 오히려 도급인은 실 손해 전부를 별도로 청구할 수 있다. 넷째, 도급계약에서 계약이행보증금의 귀속 외에 초과손해의 배상을 청구할 수 있는 것으로 정한 경우에, 그 계약이행보증금은 특수한 손해배상액의 예정(내지 손해담보)의 성질을 가질 수 있다. 이 경우 도급인은 계약이행보증금의 귀속 외에 초과손해를 입증하여 그 배상을 청구를 할 수 있다. 다섯째, 계약이행보증금은 손해배상액의 예정의 성질과 위약벌의 성질을 겸유하는 경우도 있다. 이 경우 계약이행보증금은 손해배상 기능을 가지는 손해배상액의 예정의 부분과 계약불이행에 대한 제재의 기능을 가진 위약벌의 부분으로 구분된다. In most cases, the agreement of cancellation charge is performed to compel the performance of contract, to simplify compensation for damage, or to lynch for breach of contract. In this thesis, the concept of cancellation charge is interpreted with more pliability to reflect the actual condition of contract. It means that cancelation charge can be admitted as not only a kind of liquidated damages with accepted reduction or penalty for breach of contract, but also a kind of security deposits, security damages, or both. Sure, it is presumed that a cancellation charge is a liquidated damages by article 398(4) of korean civil law, so a cancellation charge is a liquidated damages unless a specific agreement has been made between the parties. This view on cancellation charge is applied in the Supreme Court about the contract deposit in case of contract for work. First, without agreement reverted, the contract deposit has nature of down payment. In the situation where the only deposit is provided, the contract for work can be cancelled according to article 565 of korean civil law. Second, the contract deposit is considered as security deposits or security damages without specific agreement that contract deposit is regarded as cancellation charge. In this case, the orderer has responsibility to examine occurrence and range of damage to get security damage from contractor. Third, the contract deposit only with agreement reverted in contract work is admitted as liquidated damages. Also, with agreement of delay damage and contract deposit in contract work, the contract deposit has been considered as liquidated damages in the precedents. In this case, the orderer could not take fixed excess damages from the contractor, and the deposit can be reduced by courts when it is unfairly excessive. Forth, the contract deposit has nature of penalty for non-performance of contract when it is used to pressure performance of contract and to lynch the contractor in breach of contract. This case occurs when compensation of actual damage is admitted other than agreement reverted of contract deposit. On this occasion, Courts cannot reduced the contract deposit and the orderer can claim indemnification of actual damage separately. Fifth, the contract deposit is considered as specific liquidated damages or security damages with agreement that compensation of fixed excessive damages would be demanded besides reversion of contract deposit in contract work. The orderer can charge the contractor the compensation other than reversion of contract deposit by proving fixed excess damages. Sixth, the contract deposit has nature of both liquidated damages and penalty for breach of contract. In this case, the contract deposit is divided between liquidated damages for compensation of damages and penalty for breach of contract to restrain defaults on contract.
