Gymnastic activies are an important part of every childs overall experience in physical education. Children learn to move their bodies safely and gracefully, and learn to use their body parts in a variety of ways through gymnastic activities. They improve their strength, agility, balance, and other physical fitness, and they learn the importance of safety. Teachers can develop children's movement abilities through wise guidance and careful planning, but some teachers are hesitant to teach gymnastics for fear of children injuring. If teachers aren't skilled themselves, they won't be able to teach gymnastics effectively. Demonstration is an asset in gymnastics skill teaching. This is especially important for young children, who may have difficulty understanding some of the concept. Spotting encourages children to attempt movements they may not be ready for. Teacher should become a spotter. Teachers must have appropriate gymnastics skill for a good spotters. Therefore, this study aim to know the acquisition of movement skills of elementary school teachers' college students. For this study, subjects were choosen from students of In-Chon National University of Education. Students were devided into students in department of physical education and the rest. Students in department of physical education learned Gymnastics and teaching method, the rest learned Sports Skill 1. For the study, Handstanding against a wall, Freestanding handstanding, Cartwheel and Forward handspring were measured and analized. The results were summerized a follow: 1.Students in department of physical education passed easily in Cartwheel(65.6%) and in Handstanding against a wall or Freestanding handstanding(64.3%), but many students failed in Forward handspring(34.4%). 2.The rest had a low acquisition of movement skills. The results indicated that they should have plenty of time be learned movement skills of gymnastics and need an extracurriculum lecture.

노재희,노영식,이양범 울산대학교 1999 공학연구논문집 Vol.30 No.1
본 논문에서는, 평면상에서 이동하는 물체의 위치를 실시간으로 측정하기 위한 PSD 센서 시스템을 개발하였다. 이동물체에 적외선 광원을 설치하고 이 광원으로부터 적외선광이 PSD 센서에 입사 되도록 한다. 센서로부터 얻은 광원에 대한 위치정보를 이용하여 실제 광원의 위치를 계산하기위한 알고리즘으로 파라미터 켈리브레이션과 신경 회로망을 이용한 방법을 제안하였다. 또한, 이동물체의 위치를 실시간으로 측정하기 위하여 PSD 센서를 이동공간 상부에 고정시키고 이동로봇 상에 적외선 광원을 설치한 후 이동 중에 있는 로봇의 위치를 측정하였다. 결과적으로 개발된 시스템으로부터 얻은 위치 정보는 매우 만족할 만큼 정확성이 있음을 보였다. In this thesis, PSD(Position Sensitive Detector) sensor system that estimates position for moving objects in 2D plane is developed. PSD sensor is used to measure the position of an incidence light in real-time. To get the position of light source of moving target, a new parameter calibration algorithm and neural network technique are proposed and applied Real-time position measurements of the mobile robotwith light source is examined to validate the proposed method. It is shown that the proposed technique provides accurate position estimation of the moving object.

MeV ion implantation has been recently employed in the field of CMOS retrograde well engineering. An issue on MeV ion induced damage is critical especially in forming a buried layer below the well. Defect formation by high energy ion implantation has a significant characteristics in that the lattice damage is concentrated near Rp and isolated from the surface. In a TEM image as-implanted damaged layer appears as a dark band, where secondary defects are formed upon annealing. Si self-implantations were done to reveal the intrinsic behavior of secondary defect formations. Experimental results of B and P implantations were compared to those of Si case. TEM observations showed that interstitial type secondary defects are exclusively formed at around Rp. DCXRD rocking curve analyses indicated that an isolated layer of (+) strain is built up at around Rp after strain relaxation by annealing. SIMS anlayses showed that background impurities are gettered exactly at which secondary defects are formed. Gettering effieciency was found to be much related to the amount of stain field according to DCXRD analyses. A model experiment for the interaction between defects revealed that recombination of point defects with the opposite sign is responsible for defect annihilation instead of mass flow.

Apparatus activities play a large role in the child's overall physical development, especially, horizontal bar exercising benefits the arm and shoulder. In comparizon with activities on other apparatus, activities performed on the horizontal bar extremely difficult for elementary school children. Proficiency on this apparatus depend upon a child's level of arm and shoulder girdle strength and endurance. Movement challanges should be designed to allow children with minimal levels of fitness to perform movements within their own level of ability. The elementary school program with the horizontal bar should be limited simple stunts. To perform many of the more complicated stunts on the bar, sufficient arm strength is necessary to pull the body up and over the bar. Therefore, this study was to suggest the ways of the effective lesson of activities with the horizontal bar for elementary school children. The results were summerized a follow: 1. A quantities be learned is too numerous. 2. Some skills are not established as staircase to their approximate order of difficult between grades. 3, There are in appropriated skills for the children's ability levels, some are too difficult.Activities in the curriculum of elementary school is in appropriated should be regulated

This study aims to know the physical fitness of elementary school teachers' college students. For this study 275 subjects(72male, 203female) were choosen from freshmen of In-Chon National University of Education. Each subjects performed a T. K. Cureton's Physical Fitness Test. This test is composed of 3Balance Test, 3Flexibility Test, 3Agility Test, 3Strength Test, 1Power Test, and 5Endurance Test. The results are as follows; 1. Many male students result out to be good grade(70.83%), but female students not good physical fitness(54.18%) Therefore female students must develop the physical fitness. 2. Male students passed easily in Agility Test(70.83%), but many female students failed in Balance Test(47.22 %) This results indicate that Balance exercise is needed for female students.

Tense-distinction is the chief characteristic of verbs, including the category of grammartical number, person, mood and voice. Frequently we are apt to think tense stands for time, but it is not always true. According to Mr H. Sweet tense is primarily the grammartical expression of distinctions of time. This means, what we call, tense itself is a counterpart of concept of time. As we know tense consists of two kinds, simple present (e.g. he speaks). and simple past (e.g. he spoke). In English there is one tense of the past time, the pretererit. But the use of it has various meanings. When compared with classic grammar, past tense is devided with into perfect and imperfect. Perfect can not be fitted into the simple series. It represents the present state as the outcome of past events. Perfect states the affairs briefly and plainly. On the contray in imperfect we can keep feeling deply imprinted on our memory. Accordingly if we can assume pefect is past of direct and simplicity, imperfect is that of indirect and suggestion. and now we can further study the expanded forms which are called continuity or progressive form. The expanded forms of verbs indicate the progress of a movement or the duration of time as a general rule. But in certain circumstance there are obscure differences between expanded forms and common forms, that is it means incompletion, and contains the meaning of relations with continuity or progressive. In a word if we compare these three forms to some words, perfect will be compared to "see", imperfect "look", and expanded "watch".

In the management of Sexually Transmitted Disease (STD), contact tracing is most important and the knowledge of sexual partners engaged in the transmission of STD is fundamental. In this regard the medical records of the 5002 STD patients at the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul from Jan. 1986 to Dec. 1990 were studied to gain insights in this matter. The results obtained were as follows: 1) As the source of infections for 5002 patients, the so called ‘high risk group ’comprised 72.5%, which includes prostitutes 33.6%, hostesses 22.0%, and call girls 17.0%. Girl friends, acquaintances, casuals, wives and bargershop girls accounted for 9.9%, 4.1%, 3.6%, 3.3%, and 1.3% respectively. Compared to the result of previous study, from 1979 to 1985, increase is marked in girl friends from 4% to 9.9%, and wives from 2.1% to 3.3%, while slight decrease is noted in ‘high risk group ’from 84% to 72.5%. 2) As for the age of patients, the mean age was 27.2 years, and 83.5% of patients belonged to the age group of 16 to 30. In patients under 21 years of age which comprised 8.1% of patients, prostitutes were revealed as the sources of infection in 53.7% of the cases. 3) Previous STD history was 0.94 times the average, with a relatively high score in the group considered to be infected from wife (1.36) and the barbershop girl group (1.06). 4) At the infective contact, some 40.2% of the patients practiced oral sex. In particular, barbershop girl group practiced oral sex most frequently (73%), and the wife group in the least (17.9%). 5) Nongonococcal urethritis (NGU) comprised a statistically significant high percentage of STDs in wife group (70.6%) and the incidence of postgonococcal urethritis rate was also the highest in wife group (57.1%)
