오늘날 네트워크의 급속한 발전에 더불어 정보화의 가속화는 보안 문제가 크게 부각하고 있다. 이에 마그네틱 카드, IC 카드 등을 이용하여 개인을 식별하는 다양한 보안 시스템들이 개발되고 있으나 분실, 복사, 고의적 양도에 의한 부정사용 등의 문제로 인해 그 해결책이 되지 않고 있으며 이에 대한 해결책으로 생체인식(Biometrics)을 이용한 개인식별 시스템[1]이 제안되어 연구가 진행되고 있다. 본 논문은 기존의 생체인식 시스템 중 가장 활발하게 활용되고 있는 지문인식 시스템이 가지고 있는 환경적인 요소나 물리적 요소에 의한 인식률 저하를 보안할 수 있는 시스템을 새롭게 제안한다. 지문인식은 사용의 편리함과 저가의 초기 투자비용, 그리고 소형화의 가능으로 생체인식 중에서 실생활에 사용되기 가장 적합한 기법으로 여겨져 다양한 응용 범위에 널려 사용되고 있다. 따라서, 제안 시스템은 기존의 지문인식 시스템을 기반으로 하여 손가락에서 추가적인 생체정보를 이용함으로써 지문인식 시스템이 갖은 단점을 보안하면서 인식률 향상과 효율적인 활용이 가능한 시스템을 제안한다.

The purpose of this study was to research the opinion and acknowledgement about the clinical chronic disease care system subject to Medical Practitioners that copied the internal medicine and family medicine as a treatment subject and was fulfilled in the purpose of providing a basic data for the improvement and stable establishment of the chronic disease care system and the high blood pressure and diabetes mellitus patient's promotion of health. Results from the research the internal medicine was 79% and the subject's average age was 52.3 years, the proportion that the high blood pressure and the diabetes mellitus took was average 28% and the interest about the system was 65.9%. In the chronic disease care system expansion status the opposition was 75.7%, and the detail field knowledge level was 56.9%. In the opinion field about the system, all fields were shown negative. The chronic disease care system is an important government policy enforcing purposed to effectively manage the yearly increasing chronic disease, but the due to the cold attitude of Medical Practitioners that must actively accept it, the stable establishment of the system is being concerned. Therefore even if it's a good policy if it cant gain the support and agreement of the accepter, in the future when trying to implement a system there should be no idleness in the effort to gain cooperation and understanding to relevant involved ones.

The effect of gamma irradiation on physico-chemical properties of salted sea mustard (Undaria pinnatifida) was investigated. Chlorophyll and carotenoid pigment of salted sea mustard were partially decreased by irradiation. However there was no significant difference in the retention rate of pigment between control and 2 kGy-irradiated samples after six months of storage at around $10^{\circ}C$, ranging values of 74 to 77% in chlorophyll and 54 to 56% in carotenoid. Total organic acids and volatile acids associated with the organoleptic quality of sea mustard increased in the samples of lower salt concentrations and of higher storage temperatures. The softening of sample tissue by irradiation was shown to be correlated with the extraction properties of alginic acid.

This study is to make legal suggestions concerning the legal status of the physical therapists and the their clinics io Korea. This study compares the legal status of the physical therapists with that of the optical and dental technicians, and reviews the current system of the American physical therapeutic clinic. 1. Under the supervision of the doctor or dentist' in Article 1 of Law concerning the Medical Technician should be deleted or changed into 'by the request of the doctor or dentist'. A new independent law should be mode only fer the physical therapist from the general law that stipulates the legal status of other similar medical technicians. 3. The legal status of the physical therapeutic clinic should be stipulated in the regulations for the application of the law as that of the dental technician does. The modification of the medical services, the medical expences, waiting time, the easy access to the clinic of farmers, fishermen, urban laborers, and handicapped people, and the development of the area of the physical therapy.

The aim of ear operation is to cease otorrhea and to restore hearing. The ceasation of otorrhea and the graft of tympanic membrane are reached to successful stage, and yet hearing restoration process still remains further to need a matter of development. Authors carried out 67 cases hearing restoration operation among 154 patients who had been undertaken mastoid-tympanoplasty during period of Feb. 1978 through March 1979. 54 cases have been followed for this study among 67 cases hearing restoration operation. The used material of operation are almostly incus and some cases with TORP. This paper is dealing with its surgical method and postoperative audimetric study.

여느 기업들과 마찬가지로 농장을 운영하는 목적은 이윤창출이다. 높은 이윤을 창출하기 위하여 농장은 우선 생산성을 극대화하기 위한 노력을 기울인다. 지난 8개월 동안 '잘되는 농장은 잘되는 이유가 있다.'라는 제목으로 생산성 향상을 이루기 위한 요인들로 습도관리, 환기관리, 물 관리, 차단방역관리, 사료관리, 계군 모니터링, 기록관리, 그리고 혹서기 관리에 대하여 연재하였다. 생각하는 각도에 따라서는 생산성 향상을 위해 제시된 요인들이 '너무나 당연한 사항들 아닌가?' 라고 쉽게 말 할 수도 있을 것이다. 그러나 필자의 경험상 그것은 그리 간단한 문제들이 아니다. 농장의 생산성을 향상시키기 위한 이들 요인들 가운데 각 농장별로 적합한 요인들을 분석하여 농장별 맞춤형 사양관리를 적용하여 농장의 생산성이 향상되는 결과를 얻을 수 있었지만 이러한 요인들을 농장에 적용하는 과정이 모두 원활하게 이루어진 것은 아니기 때문이다. 때로는 짧은 시간 내에 필자에 의해 제시된 방법들이 받아들여지기도 했지만, 생산성을 올릴 수 있는 좋은 방법들이 농장에 정착되기까지 수년이 걸리기도 했다. 양계전문병원 개원 첫해부터 현재까지 13년간을 되돌아볼 때 농장에 수의서비스를 제공하는 사람의 입장에서는 제시된 요인들이 농장에 적용되면서 생산성이 향상될 때 보람을 느끼게 된다. 보다 긍정적인 마인드를 가지고 잘 되는 농장의 잘 되는 이유를 다시 한 번 생각해보고 농장에 도움이 되는 방향으로 적용해 보길 바란다. 이번 호를 끝으로 잘되는 농장 시리즈를 마감하면서 농장의 생산성에 영향을 미치는 기타 요인들에 대해서 점검해 보기로 하자.

Nowadays, Cone-Beam CT is widely supplied in dental clinics, the distribution rate in south korea is highly ranked worldwidely. Recently, The number of Cone-Beam CTs reached 10 thousands according to national healthcare system report. Also, dental manufacturers released many kinds of In-house 3D digital printers, the distribution rate of which rises rapidly in dental clinics. Accordingly, using Cone-Beam CT data and Intraloral scan data, the application of implant guide surgery is widespread in a unit of private clinic. Through the previous articles, the latest methods of computer-guided implant surgery are reviewed, and also the considerations for precise and reliable guide surgery are summarized.

The open Hospital Attending Physician System has been discussed and operated for developing the efficiency and the substitutes for an increase in medical expenses, for overlapping investment in medical resources, and for normalization of medical delivery system. This study assessed the related factors to the acceptance and introduction of Attending Physicians on ophthalmologist. Data was collected mail response to 179 ophthalmologists in 2005. Applying multilevel logistic regression, we examined the relationship between their acknowledgment, attitude and acceptance of the open Hospital Attending Physicians System. The percentage of participation in Hospital Attending was indicated to be 3.9%. The 44.7% of all participants agreed to adopting the Hospital Attending, 33.5% of doctors are willing to participate in the future. The positive and normal attitude of physician toward the Hospital Attending is 6.6 times (95%CI 1.315, 33.138) and 55.2 times(95%CI 11.352, 268.347) more than that of negative after adjustment for other variables. Attitude was found to be the important factor influencing physicians' participation in the Attending Hospital. Thus, it is need to development and implication for the strategies that lead the practical necessity and positive attitude toward the Attending Hospital.

전반적인 피부세포의 생리적 지능 자하로 인한 자연노화와 더불어, 여러 피부 스트레스 요인들이 다양하게 작용하여 발생하는 외인성노화를 방지하거나, 개선할 수 있는 항노화소재로서의 개발 가능성을 알아보기 위해, 예로부터 항염활성이 있다고 알려진 oleanolic acid(OA)를 포함한 ursolic acid(UA), betulin, betulinic acid(BA) 등의 triterpenoids가 어떻게 피부에서의 항노화 활성을 나타내는지를 알아보았다. 시험 결과, OA는 자외선에 의한 각질형성세포에서의 PGE$_2$ 생성과 섬유아세포(NHF)에 의한 matrix metalloproteinase-1(MMP-1) 분비를 억제하였다. 그리고, NHF의 procollagen 생성을 촉진하였으며, 이런 procollagen 생성촉진활성이 in vivo에서도 발현되는 것을 무모생쥐의 실험을 통해서 확인하였다. 또한 OA는 각질세포의 증식과 분화를 촉진하여 표피세포로 하여금 세라마이므와 필라그린 생성을 증가시키도록 하는 작용도 있음을 보여주었다. 더불어 실험한 UA, betulin, BA 들은 비록, betulin, BA의 경우 세포 독성이 다른 물질 들에 비해 높았고, UA가 각질세포의 분화를 오히려 억제하는 양상을 보이기는 했지만, 대부분의 기능은 OA와 유사하였다. 피부세포보호작용과 진피 기질물질에 대한 작용, 그리고, 표피의 장벽기능과 보습기능에 대해 시험한 본 연구는, 식물성분인 triterpenoids가 피부를 위한 항노화소재로서의 개발 가능성이 있음을 확인하는 계기가 되었고, 그 중에서도 OA가 보다 우수한 항노화 소재가 될 수 있음을 시사하고 있다.
