In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Purpose: The aim of this study was to evaluate the normal values of regional cerebral blood flow (rCBF) and cerebrovascular reserve (CVR) in normal children to aged volunteers using Tc-99m HMPAO. Materials and Methods: Thirty four right-handed normal volunteers (20 males, 14 females, mean age 40.3±24.9 years, range 4 to 82 years) were underwent rest/acetazolamide (ACZ) brain SPECT using Tc-99m HMPAO and the sequential injection and subtraction method. rCBF was estimated on the basis of a semiquantitative approach by means of right/left ratio, region/cerebellum and region to whole brain ratios in frontal, parietal, temporal, and occipital lobes, basal ganglia, thalami, and cerebellum. CVR was measured by means of % perfusion increase calculated as % mean count change compared to rest rCBF in each regions. Results: Mean values of right to left ratios range from 1.004 to 1.018. rCBF was highest in cerebellum and lowest in basal ganglia and thalami. Frontal and temporal rCBF decreased while occipital and thalami rCBF increased according to age. No sexual difference of rCBF was noted. Mean CVR was 29.9±12.9%. Mean CVR significantly increased to late teens, and declined thereafter. After 6th decade, CVR in both frontal lobes, left parietal lobe and right basal ganglia decreased significantly with advancing age. There was no sexual difference of CVR. Conclusion: Quantitative assessment of CVR was possible by ACZ Tc-99m HMPAO brain SPECT. It revealed that rCBF and CVR changed according to age in normal Korean volunteers. There was no sexual difference.

Y. J. Moon, J. H. Song, J. S. Kim. A Kinematic Analysis of Snatch Technique in Weight-Lifting. Korean Journal of Sport Biomechanics, Vol. 14, No. 2, pp. 41-55, 2004. This study analyzed snatch technique in weight-lifting performed by female gold, silver, and copper medalists at the 75kg level in the 2002 Pusan Asian Games and obtained the following conclusions. 1. KSH used more extensor in the waist than those in ankles, knees, or hip joints during the second pull, So further training is required to manifest both each of joints and waist extensor effectively and thus for the line from shoulders through barbell to hip joints to form a smooth vertical pattern. 2. Contrary to those in other countries, Korean athlete KSH tended to be swift in starting but slow in the second pull section, showing less effectiveness in movement during the second pull; therefore, they must try to exert a swift movement in lockout. 3. KSH showed slowdown in the speed, which was a factor interfering with performance during second pull, despite the great maximum speed of moving barbell. It is important to use barbell sufficiently not to reduce the speed of vertical movement but rather to keep the speed increasing. 4. KSH, who kept doing inefficient movements such as failure to perform swift lockout after lifting the heel at the maximum angle of lower limbs, needs to reduce this meaningless extension of ankles, knees, or hip joints to exert energy effectively.

Many full searchblock matching (FSBM) architectures have been proposed for the motion estimation. However, the FSBM architectures need many computations and a lot of external memory accesses which are the main source of the power consumption. We propose an efficient low-power architecture for the full search block matching (FSBM) motion estimation by eliminating unnecessary computations and data reuse. Implementation results show the proposed motion estimator can save maximally about 9.3% power dissipation than a previous motion estimator.

This study examined the effects of the gender and the cognitive style which contribute to cooperative learning of elementaiy school children's competence in the observation of living things. The purpose of this study was to provide a basis for the effident teaching and learning in cooperative learning of elementary school children through careful analyses of children's observation. Results showed characteristic patterns of cooperative observation according to the gender and the cognitive style of children. The findings indicated that the field-independent groups reported more kinds observation than the field-dependent groups. The findings indicated that the girl's groups reported more kinds observation than the boy's groups except on animals. The effects of the gender on the observation of animals was not significantly different. Results of the analysis on the degree of focused observation showed that the field-independent groups reported more the degree of focused observation than the field-dependent groups and the girl's groups reported more the degree of focused observation than the boy's groups. As a result, the cognitive style and the gender could be one of the factor involved in the observation oh living things, therefore the further research of teaching methods and learning strategies should be encouraged in relation to this factor.

본 연구는 부산지역의 주요기업 변화를 살펴보기 위해 매출액 기준 전국 상위 1,000대 기업에 속하는 부산기업을 조사하여 비교분석을 실시하였다. 분석결과 2005년에 전국 1,000대 기업 중 46개 기업이 부산에 소재하였는데, 2019년에는 12 개가 줄어든 34개 기업만이 전국 1,000대 기업에 포함되었다. 또한, 전국 상위 1,000대 기업의 매출액 기준으로 부산지역 기업의 매출액 비중은 2005년 1.6%에서 2019년 1.4%로 줄어든 것으 로 나타났다. 이는 수도권 집중현상이 점차 강화되고 있기 때문이다. 한편, 부산지역 매출액 기준 상위 10대 기업은 많은 변화가 있었는데, 2005년 상위 10대 기업 중 2019년에도 상위 10대 기 업에 포함된 기업은 ㈜한진중공업, 르노삼성자동차(주), ㈜부산은행, ㈜서원유통 등 4개뿐인 것 으로 나타났다. 통계적 인과 관계는 확정할 수 없으나 지역 대기업의 쇠퇴 및 유출과 지역의 쇠퇴가 동시에 이루어지고 있어 지역 경제의 침체와 대기업의 쇠퇴 및 유출이 상당한 관계가 있음을 유추해 볼 수 있다. 특히 2011년 이후 지역 주력 제조업 기업들이 1000대 기업 진입에 실패하였다는 점을 주목해 볼 필요가 있다. 지역 제조업 대기업의 이탈 또는 쇠퇴는 지역 생산성 하락에 영향을 미 쳤을 가능성이 높고, 낮아진 지역 산업 생산성이 지역 경제성장률 둔화에도 영향을 미칠 가능성 이 있다. 따라서 지역의 경제활력 저하 문제를 제고하기 위해서는 지역 산업구조 개편 문제와 생 산성 향상 방안에 대한 고민이 필요하다.

This study proposes a technique utilizing virtual information instead of real information in a teleoperated wiping operation. A teleoperation system composed of a master manipulator, a slave manipulator, and a real-time control system is used for this study. Both the master and slave manipulator have a kinematic structure effectively conveying and following the operator’s command respectively. The master manipulator uses DC servo motors to do a major role for counter balancing. A force sensor attached at the end of the slave manipulator’s end effector is used to measure a contact force. MATLAB/xPC Target is used for real-time control of the teleoperation system in Windows OS. This study proposes algorithms for generating the virtual force and the virtual velocity. They are generated as the master manipulator’s grip moves up and down, and back and forth. A force-force control technique proposing in this paper uses the virtual force as a reference input for the contact force control, and uses the virtual velocity as a reference input for control the slave manipulator’s horizontal movement. A PID controller is used as a local controller for the contact force control. In order to show the effectiveness of the proposing force-force control technique, experiments are performed on a plastic plate with two bumps.

The annual air pollution emissions from construction and agricultural equipments were estimated from 1987 through 2000. The annual numbers and operation hours of 5 major construction equipments (Excavator, Bulldozer, Loader, Fork lift, Crane) and 3 major agricultural equipments (Power Tiller, Agricultural Tractor, Combine) were investigated for emission estimation. And monthly variation factors of operation hours of construction equipment were investigated too. The NOx emission from construction equipment have been gradually increased since 1987 to 1997, but sharply decreased as -45% in 1998 due to economic crisis in Korea. The NOx emission was estimated as 64,300 ton/year from construction equipment, and as 23,300 ton/year from agricultural equipment in 2000.
