본 논문은 유비쿼터스 의료를 위한 의료영상의 무선전송의 개발을 목적으로 한다. 컴퓨터 시스템의 발달로 인해 의료 장비와 의료 기록 체계에 대한 많은 변화가 일어났다. 그 중 병원내의 진료 및 의무기록을 자동화하고 관리하는 HIS(Hospital Information System) 시스템과 환자에게서 촬영된 영상에 대한 관리 체계인 PACS(Picture Archiving Communication System)은 대표적인 예라할 수 있다. 이러한 자동화된 진료 시스템은 병원 내에 있지 않을 경우 이용이 곤란하며, 응급상황이나 의사 부재시에 신속한 영상 판독이 요구되는 경우 이를 즉시 수행하기는 곤란하였다. 이러한 이동에 따른 단점을 보완하기 위하여 각 의사마다 지급된 PDA를 사용하여 병원내의 영상 획득 장치로부터 생성된 환자 영상을 원격에서 CDMA 망을 사용하여 검토할 수 있는 시스템을 구현하였다. 이를 위하여 의사 및 환자의 계정 관리와 환자 영상을 영상획득 장치로부터 수신 받아 각 의사별로 할당하도록 하는 서버 시스템을 구현 하였으며, PDA를 사용하여 서버에 접속하여 환자의 영상을 검토할 수 있도록 구현하였다. 개인별로 시스템 사용에 대한 인증을 위하여 PDA에서는 데이터베이스 RDA(Remote Data Access) 방식을 사용하여 서버 데이터베이스를 엑세스하였으며, 환자 영상을 서버로부터 다운로드 하기 위하여 FTP(File Transfer Protocol)를 사용하였다. 실험 결과 한 파일의 크기가 0.37Mbyte 인 832x488*24 영상 30매를 보낸다고 가정하였을 때 약 90초 정도의 시간이 걸렸으며 이는 긴급히 또는 원격에서 영상의 수신과 검토에 문제가 없음을 나타낸다.

Objectives: Early intensive interventions are very important for children with autism spectrum disorder. We examined the actual conditions of hospital-based early intensive interventions for autism spectrum disorder in Seoul, in order to help develop and implement an evidence-based early intensive intervention model for use in Korea. Methods: Nine hospital-based institutes running an early intensive intervention program for children with autism spectrum disorder responded to a questionnaire in September 2014. They provided a brief introduction to their program, explained its theoretical bases, and reported the number of children, their age, intervention time, duration and so on. Results: In the majority of the institutions, the intervention was provided for over 20 hours every week, and the theoretical bases included various applied behavioral analysis (ABA) methods and other therapies (language and occupational therapy). The therapist-child ratio ranged from 1:1 to 5:3. Various types of therapists were involved, including behavioral analysts, special education teachers and (or) language pathologists. There was only one clinic where the behavioral analyst was the main therapist. Usually, the intervention was terminated just before the child entered elementary school. The main merit of the hospital-based intervention in our survey was the effectiveness of the multi-disciplinary intervention plan and its other merits were the accuracy of the diagnosis, its ability to be combined with medicine, and so on. Conclusion: The current hospital-based early intensive intervention programs provide interventions for over 20 hours per week and employ multidisciplinary approaches. However, there are very few institutes for children with autism and very few intervention specialists and specialist education courses in the country. We need more educational programs for intervention therapists and have to try to develop policies which encourage the implementation of an evidence-based early intensive intervention program nationwide.

Pilon fractures involving distal tibia remain one of the most difficult therapeutic challenges that confront the orthopedic surgeons because of associated soft tissue injury is common. To introduce and describe the diagnosis, current treatment, results and complications of the pilon fractures. In initial assessment, the correct evaluation of the fracture type through radiographic checkup and examination of the soft tissue envelope is needed to decide appropriate treatment planning of pilon fractures. Even though Ruedi and Allgower reported 74% good and excellent results with primary open reduction and internal fixation, recently the second staged treatment of pilon fractures is preferred to orthopedic traumatologist because of the soft tissue problem is common after primary open reduction and internal fixation. The components of the first stage are focused primarily on stabilization of the soft tissue envelope. If fibula is fractured, fibular open reduction and internal fixation is integral part of initial management for reducing the majority of tibial deformities. Ankle-spanning temporary external fixator is used to restore limb alignment and displaced intraarticular fragments through ligamentotaxis and distraction. And the second stage, definitive open reduction and internal fixation of the tibial component, is undertaken when the soft tissue injury has resolved and no infection sign is seen on pin site of external fixator. The goals of definitive internal fixation should include absolute stability and interfragmentary compression of reduced articular segments, stable fixation of the articular segment to the tibial diaphysis, and restoration of coronal, transverse, and sagittal plane alignments. The location, rigidity, and kinds of the implants are based on each individual fractures. The conventional plate fixation has more advantages in anatomical reduction of intraarticular fractures than locking compression plate. But it has more complications as infection, delayed union and nonunion. The locking compression plate fixation provides greater stability and lesser wound problem than conventional implants. But the locking compression plate remains poorly defined for intraarticular fractures of the distal tibia. Active, active assisted, passive range of motion of the ankle is recommended when postoperative rehabilitation is started. Splinting with the foot in neutral is continued until suture is removed at the 2~3 weeks and weight bearing is delayed for approximately 12 weeks. The recognition of the soft tissue injury has evolved as a critical component of the management of pilon fractures. At this point, the second staged treatment of pilon fractures is good treatment option because of it is designed to promote recovery of the soft tissue envelope in first stage operation and get a good result in definitive reduction and stabilization of the articular surface and axial alignment in second stage operation.

The Korean government achieved the universal coverage of health insurance in July 1989, and concomitantly introduced a new measure of regulated health care delivery system in using medical care. There are three reasons why the government took the new health care delivery system. Firstly, there was ample room for improving the allocative efficiency in the use of medical facilities. And the second one was to constrain the dramatic increase of medical demand under health insurance. Thirdly, and the most important reason was to alleviate the patient crowdedness in big general hospitals, particularly tertiary hospitals. There are essentially two different ways to control the use of health care : one is to cut the demand for health care, and the other to regulate behaviors of providers through the use of incentives/disincentives, demand-side approach or supply-side approach. The objective of this study is to examine whether or not medical care utilization behaviors under health insurance scheme have been changed among medical facilities such as clinic, hospital, general hospital and tertiary hospital in comparison with those before and after the introduction, particularly whether the patient crowdedness in tertiary hospitals has been alleviated or not. In order to conduct this study, the insurance claim data during the period of January 1989 and July 1992 were analyzed by focusing on diagnosis of both inpatients and outpatients, and especially the fifteen most frequent diseases in ambulatory care and the seven most frequent diseases in hospitalizatio. In addition, the same analyses were made on the changes in medical care utilization by specialty department. This was because the five departments, such as family medicine, ENT, eye, dermatology and rehabilitation, were exempted from applying the regulated health care delivery system in tertiary hospitals. The study revealed that a remarkable alleviation effect in the crowdness was noted for tertiary hospitals. This effect was most conspicuous for the most frequent mild diseases of both inpatient and outpatient care. For example, the fifteen most frequent OPD care at tertiary facilities have decreased as much as by 40%, of which 34% belonged to the cut in initial visits. Meanwhile, the proportion of those who used general hospitals and private practitioner's clinics have increased due to the shift of patients. The cases from the five special departments were also decreased, but not so much as other departments. A problem was noted that, as time passed by, the decreasing tendencies of crowdness at tertiary hospitals due to the regulated system became slightly smaller. Therefore, through complementary remedies are needed for the future implementation.

바이러스성 출혈성 패혈증 바이러스(VHSV)는 넙치를 포함한 어류 양식의 막대한 피해를 일으키는 바이러스 병원체이며, VHSV가 생성하는 6개의 바이러스 단백질들 중에서 NV 단백질이 병원성에 관여하는 것으로 알려져 있다. VHSV-감염 넙치를 이용한 전사체 마이크로 어레이의 선행 분석 결과에 의하면 VHSV 감염이 해당과정 효소들의 mRNA 발현을 억제함으로써 넙치 세포에서 ATP 생성을 감소시켰음을 알 수 있었다. 이들 결과를 토대로, 본 연구에서는 VHSV NV 단백질이 해당과정 효소인 glucokinase의 발현에 미치는 영향을 검토하였다. 본 연구의 결과에 의하면, NV 단백질은 넙치 세포에서 glucokinase의 mRNA 발현을 감소시켰으며, 새롭게 동정한 glucokinase의 유전자 프로모터의 활성 실험결과, NV 단백질이 glucokinase의 프로모터 활성을 저해함을 알 수 있었다. 이와 같은 작용 결과들로 인하여 VHSV NV 단백질의 발현이 세포 내로의 포도당 흡수 또한 감소시켰다. 이러한 결과들은 VHSV NV 단백질이 유전자 발현의 전사 수준에서 음성적으로 해당과정의 효소 발현을 조절함을 의미하며, 결국 세포 내 에너지의 결핍으로 넙치의 폐사로 이어질 가능성을 보여주는 것이다.

The tuberculin test have been widely utilized to diagnose tuberculosis of the dairy cattle. It was reported that approximately 70% of the dairy cattle with positive tuberculin reaction in Korea had been non-pathogenic lesion. So the studies on the specific method to diagnose tuberculosis of them is really need in Korea. Therefore this study investigated upon the diagnostic method for cattle tuberculosis in the aspect of cellular-immunology. The results obtained in this investigation are summarized as follows: 1. All the tuberculin tests to the swine inoculated with BCG.(B group), Mycobacterium avium (A group) and Mycobacterium smegmatis (S group), respectively, were represented high positive reaction and were no differences in the species of inoculated bacteria. 2. In the migration inhibition test using Iymphocyte in circulating blood of the swine inoculated with three species of acid-fast bacteria respectively, the test to A group was represented slight positive for migration in the presence of $15{\mu}g/ml$-PPD and the other reaction were clear and total positive for migration inhibition in the presence of $25{\mu}g/ml$-PPD or more, and the test to B group was the same results as to A group approximately. The test to S group was represented slight positive for migration inhibition in the presence of $15{\mu}g/ml$-PPD, but the results were the same in the presence of $25{\mu}g/ml$-PPD and $35{\mu}g/ml$-PPD. These results showed that there were remarkable differences between group A, B and group S in the presence of $25{\mu}g/ml$-PPD and $35{\mu}g/ml$-PPD. 3. The transformation rates of lymphocyte in PPD treated tissue culture had no significance without any relation between PPD treatment and non-treatment but A group and B group showed significance. And A group and B group showed high significance in comparison with N group and S group in the LSD examination. 4. The infection rated in lymphocyte of BCG inoculated after 3 days tissue culturing were represented those of high infection but its cellular degeneration rates almost did not change. The infection rates in bacilli in N group and S group were low but after 3 days inoculation it shewed higher cellular degeneration.

The relationship between palpable ovarian structure and milk progesterone levels were determined in 144 dairy cows. Depending on the ovarian structure and diseases were divided into two groups, Group I (absence of functional luteal tissue in ovary and <2ng/ml in milk progesterone levels) and Group II(presence of functional luteal tissue in ovary and ${\geq}2ng/ml$ in milk progesterone levels) 1. Among 69 cows of group I, dysfunction of ovary, atropy of ovary, follicle is ovary, follicular cyst and corpus luteum albicans were 17(11.8%), 19(13.2%), 14(9.7%), 3(2.1%) and 16 cows(11.1%), and among 75 cows of group II, corpus luteum A, B and C were 16(11.1%), 17(11.8%) and 42 cows(29.2%), respectively. 2. In Group I, milk progesterone concentrations were <1ng/ml in 55 cows(79.9%). Conversely in Ggroup II, milk progesterone concentrations were ${\geq}4ng/ml$ in 55 cows(73.3%). 3. The mean(${\pm}SE$) concentrations of milk progestsrone in the Group I and II were $1.62{\pm}0.45$ and $7.64{\pm}0.68ng/ml$, respectively, and CR test showed the difference in milk progesterone concentrations between the two groups to be statistically significant(p<0.01). 4. The mean(${\pm}SE$) concentration of milk progesterone in cows with corpus luteum A, B and C were $8.11{\pm}1.83$, $8.48{\pm}1.30$ and $7.12{\pm}0.82ng/ml$, respectively, there was no significant relationship between palpable corpora luteum structure and milk progesterone concentration. 5. The accuracy of ovarian diagnosis was 82.6 and 20.2% in the Group I and II, respectively, and Chi-square test showed the difference in accuracy between the two groups to be statistically significant (p<0.001). 6. The agreement between the rectal palpation and milk progesterone concentrations in ovarian disease was 50%.
