현대 사회는 인터넷 사용자의 증가와 제반 기술의 비약적인 발전으로 사회활동 전반에 대한 인터넷 기반 서비스가 이루어지고 있다. 이런 과정에서 발생한 중요한 문제중의 하나가 불특정 다수가 자유로이 통신을 하기 위해 개발된 인터넷상에서 사용자의 보안을 보장해주는 것이다. 최근에 와서 인터넷상에서 개인 정보유출로 인한 많은 피해가 발생하면서 정보보호에 대한 관심이 더욱 증가하고 있다. 현재 이 문제를 해결하기 위하여 많은 보안 관련 시스템들이 개발되고 있으며, 세계 각 국의 표준 기구에서는 이러한 시스템에 대한 등급을 평가하고 있다. 각 등급을 살펴보면, 시스템 개발 초기부터 정형기법을 이용하여 개발되어진 시스템들이 고등급을 획득하고 있다. 국내에서도 한국정보보호센터(KISA)에서 보안 시스템에 대한 등급을 평가를 수행하면서 정형기법을 이용하여 땅세 검증된 시스템에게 K5이상의 고등급을 부여하고 있다. 이러한 등급을 살펴보면, 시스템의 기능을 정형명세언어를 이용해서 명세하는 부분을 공통적으로 요구하고 있다. 본 논문에서는 높은 보안 등급의 IPSec 관련 시스템을 개발하기 위해서 정형명세언어인 Z를 이용해서 IPSec의 동작을 명세하였다. The modern community is moving across the whole areas based on Internet with the growing Internet users and the great technological development. One of the important things that can be problem in this community is that the Internet should assure secure networking and security mechanism for the many security-ignorant users. Recently, Due to a lot of damages like a personal drain, security concerns is growing very rapidly. Now, many security application system is developing to solve this problem and each of the world standard organizations is evaluating these security application systems. Considering the each levels, we found that system using formal methods from the initial system development process acquired the high-level. In domestic, KISA manages the evaluation of security system and gives the higher than K5 to the system that specified and verified using formal methods. In this all levels, it should be required the system specification part. In this paper, we specified IPSec using formal specification language Z to develope the high-level IPSec system.

The authors experienced a patient with insulinoma presented with neuropsychiatric symptoms. It was demonstrated that Whipple's triad is highly suggestive of the presence of an insulinoma. Therefore physicians and/or psychiatrists, who refer patients with insulinoma to third institution, always have a alertness to neuropsychiatric symptoms of insulinoma and Whipple's triad. This case also illustrated the persistence and cooperation between psychiatric and medical teams including the involvement of a neurologist, endocrinologist, and surgeon for diagnosis and treatment planning of patient with insulinoma.

Background and Objectives : Palindromic rheumatism (PR) is known to be triggered without any obviously inciting events in most patients, although, in a few cases, attacks have been noted to relate to another events such as weather change, childbirth, ingestion of certain foods, or over-exercise. The aim of this study was to characterize the triggering factors on palindromic attacks. Materials and Methods : We evaluated sixty-four patients with PR for the presence of triggering factors and the relationship between attacks and triggering factors by interview of patients. We considered that there was an probable association between episodes and PR, if episodes within 24 hours prior to PR had triggered at least 50% of all attacks and a definite association between episodes and PR, if episodes within 24 hours prior to PR had triggered 100% of all attacks. Results : In 15 patients (35.9%), there was a possible association between episodes of PR and initiating events. In 8 patients (12.5%), there was a definite association between episodes of PR and initiating events. The triggering factors were physical over-activity including exercise (19/64: 29.7%), foods, such as rawfish, crab, and chicken, including alcohol (19/96: 19.8%). However, there were no difference between the groups with and without the triggering factor in sex ratio, duration and onset of PR, the positive rate of rheumatoid factor and involved sites. Conclusion : Our observations showed that PR was triggered by physical over-activity more than in previous reports and hypersensitivity to foods was a causative factor in some patients with PR. However, patients with triggering factors had a similiar clinical profile to patients without triggering factors.

The Purpose of the study is to investigate the effect of body flexibility for competitive swimming performance. The subjects were twenty male and female of elite swimmers who were divided into four competitive swimming style. They were tested about anthropometrics and flexibility which consisted of horizontal shoulder flexibility, vertical shoulder flexibility, forward trunk flexibility, ankle plantar flexibility, and dorsiflexion. This experiment was done 10 months from Sep. 15 in 1982 to May, 31 in 1983. As the results of this experiments, conclusions were made as follows; 1. Korean elite competitive swimmers showed lots of individual difference in their body flexibility. 2. Elite swimmers showed almost the higher level of body flexibility. 3. Horizontal shoulder flexibility had significantly shown correlations to female back stroke, and male backstroke and female butterfly was related to the pulling times. 4. Vertical shoulder flexibility had shown negative correlations to female butterfly, and its correlations also had shown freestyle, backstroke, and breaststroke in male. 5. Ankle plantar flexion was related to freestyle, backstroke, breststroke, and its pulling correlations had shown male freestyle. 6. Dorsiflexion was linearly related to female butterfly, while female freestyle had shown it negative correlations.

This study investigated that the effect of rewetting agent on dentinal microtensile bond strength (μTBS). Human molars were sectioned to expose the superficial dentin surfaces. Samples were divided into two groups according to type of adhesives-Single Bond (S) and One-Step (0)], and again subdivided into five groups by different dentin surface treatment-dry for 15s (D) , blot dry (BD) or dry for 15s, and rewet with different rewetting agents[distil1ed water (DW), Gluma Desensitizer (GD) and Aqua-Prep (AP)]for 30s. After application of adhesive, composite resin was built up on the bonding surface. Each tooth was sectioned to obtain stick with 1mm^(2) cross sectional area and the μTBS was determined by EZ test. In the S group, the mean μTBS of GD, AP and BD group was significantly higher than that of DW and D group (p < 0.05). In the 0 group, the mean μTBS of AP, GD, BD and DW group was significantly higher than that of D group (p < 0.05). The data suggested that Gluma Desensitizer and Aqua-Prep could be successfully used as rewetting agents, and Distilled water could be acceptable in aceton based adhesive system only.

An epidemiological survey was conducted to estimate the prevalence of and identify the risk factors of dementia and depression in the elderly between December 1997 and August 1998 in Yonchon County, Korea. A total of 1,037 elderly aged 65 years and over underwent a two phase diagnocstc procedure. Multiple stage, random cluster sampling method was used to select the subjects. Response rate was 85.4%. For the Ist stage screening survey, the Korean Psych-ogeriatric Assessment Scale was used as a primary screening tool, which had already been standardized in Korea, and functioning and social support were assessed by ADL, IADL and APGAR. At the 2nd stage, diagnoses were confirmed according to the DSM-Ⅲ-R. And several other scales were used as supporting information for differential diagnoses and for evaluating severity. 1) Age-sex adjusted prevalence(%)[95% C.I] of dementia was 6.83[6.12-7.54](male 6.34 [5.29-7.40], female 7.09[6.14-8.04]). Prevalence of the dementia of the Alzheimer's type was 4.17[3.61-4.74](male 2.42[1.76-3.08], female 5.31[4.48-6.14]) and that of the va-scular dementia was 2.38[1.95-2.81](male 3.46[2.67-4.25],female 1.63[1.16-2.10]). 2) Age-sex adjusted prevalence(%)[95% C.I.] of depressive disorder was 10.99[10.11-11.87](male 7.59[6.44-8.73], female 1346[12.20-14.73]. Among depressive disorders, prev-alence(%)[95% C.I.] of major depressive disorder was 7.50[6.76-8.26](male 4.42[3.54-5.31], female 9.78[8.68-10.88]), that of dysthymic disorder was 2.02[1.62-2.42](male 1.37[0.86-1.87], female 2.46[1.88-3.03]) and that of depressive disorder NOS was 1.49[1.15-1.83](male 1.85[1.47-2.23], female 1.28[0.96-1.60]). 3) Five statistically significant risk factors of the dementia of the Alzheimer's type were identified : age over 85(O.R. = 10.27), illiteracy (O.R. = 4.01), alcohol abuse (O.R. = 2.98), smoking [0 < pack year ≤30(O.R. = 3.11), pack year>30(O.R. = 4.60)] and family history of dementia (O.R. = 4.85). 4) Three statistically significant risk factors of the vascular dementia were identified : illiteracy (O.R. = 3.78), history of CVA(O.R. = 26.76) and smoking over 40 pack year(O.R. = 11.15). 5) Three statistically significant risk factors of the depressive disorder were identifed : age between 75 and 79(O.R. = 2.87), past history of CVA(O.R. = 3.33) and family history of depressive disorder(O.R. = 7.16).

In order to show the effect of a vast point pollutant source on air quality of Pusan Thermoeletric Power Plant and its surrounding area, air quality around Pusan Thermoeletric Power Plant was simulated by ISCLT-2 which was supplied by EPA. For this purpose the emission amount of SO_2, NO_2 and TSP was calculated and atmospheric stability was classified for a recent decade(1985~1994) in Pusan. A result of the emission amount showed that much amount of NO_2, NO_2 and TSP are emitted from industrial area. It was clear that NO_2 is much emitted from line source and industrial area. And as a result of classification of atmospheric stability, neutral, stable and unstable state were 58%, 24.1% and 17.9%, respectivly. The result of ai quality simulation by ISCLT-2 showed that Pusan Thermoeletric Power Plant is affecting on the increse of 2.0ppb, 3.0ppb and 5.0㎍/㎥, SO_2, NO_2, and TSP respectively at its surrounding area, site A-3 which was located westward 2.2㎞ distance from Plant

합병증이 동반된 Meckel씨 게실 2례 보고

합병증이 동반된 Meckel씨 게실을 가진 환자의 치료에 대한 필요성은 과정이 문제이다. 하지만 우연히 만나는 게실의 처치는 논란 중이다. 부수적인 게실 절제술(incidental diverticulectomy)의 제안자는 증상이 있는 게실의 외과적 처치는 중요한 이환 및 사망률은 지적한다. 이를 반대하는 사람들은 전 생애를 통해 합병증의 위험성이 낮게 나타나므로 필요가 없다고한다. 게실의 예방적 제거는 개복술시 우연히 발견 될 때 시행한다. 이는 남아있는 게실이 나중에 합병증을 일으키는 것보다 술후 합병증의 위험성이 매우 적음을 알 수 있다. 저자들은 합병증이 동반된 Meckel씨 게실 2예를 경험하였기에 문헌 고찰과 더불어 보고하는 바이다. The necessity for therapy with complicated Meckel's diverticular is a matter of course.However, management of the incidentally encountered diverticulum is controversial. Proponents of incidental diverticulectomy point to the significant morbidity and mortality rates of surgical treatment of symptomatic divenicular. Other authors base their opposition to incidental diveniculectomy on the low risk of complications developing during lifetime. Prophyillctic removal of the diveniculum is indicated when it is found incidentally at laparotomy, because there are few postoperative complications and the risk exists that the remaining diverticulum may be the cause of later complication. The 2 cases of complicated Meckel's diverticulum are reported with a brief review of literature.
