Periodontal surgery can be directed to remove the irritants from the tooth surface and reduce the periodontal pocket. The purpose of this study is to compare the clinical effects after between modified Widman flap and modified flap in periodontal patients. Ninety six molar area teeth of 9 patients were used. One of sextants performed a modified Widman flap, while the other side performed a modified flap. After initial periodontal therapy, the following measurements prior to surgery(baseline) were taken : pocket depth, gingival recession, clinical attachment level, tooth mobility, bleeding on probing. Also these measurements were taken at 4 weeks, 8weeks, and 12 weeks after surgery. Significant decrease of pocket depth was shown in both techniques, and the degree of decrease was significant in modified flap than modified Widman flap at 12 weeks. Significant increase of gingival recession was shown in both techniques, and the degree of increase was significant in modified Widman flap than modified flap at 4 weeks, 8 weeks, and 12 weeks. Significant attachment gain was shown in both techniques, and the degree of increase was significant in modified flap than modified Widman flap at 4 weeks, 8 weeks, and 12 weeks. Significant increase of tooth mobility was shown in both techniques at 4 weeks, but the decrease of tooth mobility was shown at 12 weeks. Greater decrease of bleeding on probing was shown in both techniques at 4 weeks. Modified flap was better than modified Widman flap in the decrease of gingival recession and the attachment gain. These results indicate that modified flap operation is better than modified Widman flap operation in the effect of periodontal treatment.

The purpose of this research is to obtain and analyze dynamic responses from human volunteers for the development of the human-like mechanical or mathematical model for Korean males in automotive rear collisions. This paper focused on the introduction to a low-speed rear impact sled test involving Korean male subjects, and the accumulation of the motion of head and neck. A total of 50 dynamic rear impact sled tests were performed with 50 human volunteers, who are 30-50 year-old males. Each subject can be involved in only one case to prevent any injury in which he was exposed to the impulse that was equivalent to a low-speed rear-end collision of cars at 5-8 km/h for change of velocity, so called, ${\Delta}V$. All subjects were examined by an orthopedist to qualify for the test through the medical check-up of their necks and low backs prior to the test. The impact device is the pendulum type, tuned to simulate the crash pulse of a real vehicle. All motions and impulses were captured and measured by motion capture systems and pressure sensors on the seat. Dynamic responses of head and T1 were analyzed in two cases(5 km/h, 8 km/h) to compare with the results in the previous studies. After the experiments, human subjects were examined to check up any change in the post medical analysis. As a result, there was no change in MRI and no injury reported. Six subjects experienced a minor stiffness on their back for no more than 2 days and got back to normal without any medical treatment.

The purpose of this study is to analyze empirically the regional impacts mainly in the fields of demographic and industrial structure by the Seohaean highway which was constructed in the end of 2001. In general, the construction of highway often causes the impacts on adjacent regions to highway over demographic configuration, industrial structure, land use and financial condition, etc. In this sense, this empirical study analyzes the impacts of 13 regions as experimental groups and other 13 regions as comparison groups in 3 provinces(Chungnam, Cheonbuk, Cbeonneur-do), The finding of this empirical analysis is that the regional impacts on the demographic and industrial structure brought from the Sehaean highway construction has been drawn differently over regions and data units.

Although penicillin still remains the drug of choice in the treatment of gonorrhoea in many countries, treatment failures are becoming more and more coramon. Recently, the prohlem cauaed, by antibiotic resistant strains of N. gnorrhoeae has been aggravated by appearance of penicillinase producing N. gonorrheeae. Good results were reported with the use of spectinomycin, cefuroxime and efotaxime. These drugs are, as yet, quite expensive. A lower cost regimen has to be sought. In this study, the effect of fortified penicillin G was compared with kanarnycin in the treatment of uncomplicated male gonorrhoeae. The subjects were 446 rnale patients with uncomplieated gonocoacal urethritis at VD clinic of ChoongKu Public Health Center in Seoul between June and November, 1981. The patients are assigned randomly to one of the regimens. Among 181 patients treated with kanamycin, 2. 0 gm, IM, 148 recovered with 27 (19%) postgonococcal urethritis (PGU) and 39(21,6%) failed. Among 168 patients treated with fortified penicillin G, 6 mega-units IM, plus probenecid, l. 0 gm, PO., 100 recovered with 31(81%) PGU and 68(40. 5/o) failed. -countinue-

일반논문 : 고려말,조선전기 하동지역 왜구 방어체계 고찰

홍성우 ( Sung Woo Hong ),강영수 ( Young Su Kang ) 경남대학교 가라문화연구소 2012 加羅文化 Vol.24 No.-

고려말~조선전기는 왜구(倭寇)의 침입이 극심한 시기였다. 이를 방어하고자 조선 개국 이후 읍성·산성·봉수 등을 축성(築城)하였다. 이러한 방어체계를 갖추면서 어떠한 방법으로 방어 했는지를 하동지역으로 한정하여 왜구의 침입루트 및 방어체계에 대하여 고찰해보았다. 먼저 침입루트를 해안-섬진강 루트와 해안-육지 루트로 나눈 뒤, 침입 루트상에 설치된 방어시설인 읍성·산성·봉수대의 현황에 대해 살펴보았다. 문헌검토를 통해 하동지역은 다른지역에 비해 왜구의 침입 횟수가 적었고, 규모도 작았을 것으로 추정하였으며 침구(侵寇)시기는 겨울과 봄에 집중되었음을 알 수 있었다. 이러한 침입 루트와 방어시설을 살펴본 결과 지형 및 주변 유적을 통해 왜구 침입시 4단계의 방어선을 설정해 보았다. 하동지역 방어선 설정과정에서 하동지역의 방어상 몇 가지 특징을 살필 수 있었다. 첫째, 방어시설의 배치관계이다. 하동읍성을 중심으로 5km 내에 대부분의 방어시설이 존재한다는 것이다. 둘째, 하동읍성의 견고성을 뽑을 수 있다. 셋째, 산성의 규모를 보아 둘레가 1000m를 넘지 않는다. 이는 왜구가 침입시 소규모로 침입한 경우를 대비해 쌓았을 것으로 판단된다. 넷째, 산성과 봉수와의 배치관계를 보면, 봉수대는 대부분 산성 내에 위치하거나 산성 주변에 위치하는 것을 알 수 있다. 다섯째, 봉수대 배치 구도의 중요성이다. 각 방어선 마다 배치된 봉수대가 삼각형 구도를 갖추어 남해안으로 출몰하는 왜구를 효과적으로 감시할 수 있었음을 알 수 있다. The late Koryo through the early Chosun Dynasty was the period during which Japanese invasion was at peak. To defense the Japanese pirates, town walls, mountain fortress walls and beacons has been built since the foundation of Chosun Dynasty. This study attempted to know how ho these defense systems were used against the Japanese attack, the invasion routes of Japanese pirate and the defense system of the Dynasty, focusing on Hadong area. First of all, this study segmented the invasion routes into the seashore to Sumjin River and the seashore to the shore and then examined the current status of the defense systems (town walls, mountain fortress walls and beacons) built in each route. Through the investigation, this research could reach the assumption that Hadong area was less offended by the Japanese pirate than any other areas and the scale of the Japanese attack was not significant. In addition, it was thought that the periods of the attack were concentrated in winter and spring. As the result of looking into the invasion routes and the defense system through the related topographies and confirmed remains, we could picture the defense lines against the attack. Some characteristics of the defense system in Hadong area were found in the process of setting the lines. First, the arrangements of the defense system are located within 5 km from Hadong town walls. Second, the town walls are firm. Third, judging from the shape of the mountain fortress walls, they are shorter than 1000 meter in circumference. This short circumference allows thinking that they were built against small scale of offense. Fourth, the arrangement of the mountain fortress and beacons guides us to picture that most of beacons were positioned inside the fortress or around it. Fifth, the spatial composition of the beaconshas importance. The beacons, which were built on each defense line, were planned in a triangular composition. It was the effective lineup in defending the Japanese pirate landing on the southern coast.

According to the statistical annual reports in the Fair Trade Commission '06, it needs to improve that accounts for nearly 45.2% to the cases of violation of the subcontract law 18,306 of the total cases of unfair trade 40,525. It recognized that a relationship between a contract and a subcontract was not a cooperative relationship. Construction work's competition is the more cost-down and business profit than another firms through quality guaranteed and technique development during the preferable term of work, but recently to evaluate a value of firm are also reasonable factors that are a business clearness, social responsibility, moral management therefore, if you need to improve construction work's competition, you should need to improve the market economy system through establishment of the fair and free competitive system. Accordingly, this study aims to present the problem of law in conjunction with subcontract dealing, to survey a questionnaire, to present improvement plans for relative system of subcontracting, to analyze the relationship between normal construction work and special construction work.
