  • The purpose of this study was to verify the validation of exercise effect with loading deviation during rowing exercise. We performed evaluation of based physical fitness and joint torque before the experiment for finding muscle unbalance. So we recruited twenty four subjects who have bigger muscle strength in more 20% than average one. Subjects divided two groups. One is dominant upper limbs(DU) and the other was dominant lower limbs(DL). Subjects performed rowing exercise using electric equipment (Robo.gym.Humonic.korea). Exercise is performed four sets a day including 25 times a set, and three days a week. Measurement consist of evaluation of based physical fitness and joint torque using biodex(biodex system3.USA). Evaluation of exercise effect performed each week in joint torque of shoulder, lumbar and knee joint and each month in based physical fitness. Also we adapted 30% of 1RM for muscular endurance and 70% of 1RM for muscle strength as exercise load. The results showed that the difference of maximal peak torque were getting increase significantly during exercise. Also difference of various factor in based physical fitness were getting increase significantly except flexibility and agility. This interpreted that rowing exercise with loading deviation types could provide muscle strength and muscular endurance exercise in same time. These results could be interpret to two ways. One is effect of improving physical fitness for rowing exercise and the other meaned validation of loading deviation in rowing exercise. Our study is going to verify the validation of loading deviation during rowing and we found out that loading deviation could provide muscle strength and muscular endurance exercise for improving muscle unbalance. Our study can be used development of exercise equipment and program for normal people with muscle unbalance. Also that provide effect of whole body exercise to anybody.

  • The purpose of this study were two fold : first, to determine the effect of aerobic exercise on BP, pulse rate, body fat, body weight, symptoms of sterss response: and secondly, to apply the aerobic exercise on nursing practice in the healthy or ill subjects. In an attempt to investigate the physiological and psychological effect of exercise, a quasi -experiment, non-equivalent control group pre-test & post-test design was planned. Experiments were carried out from July 4, through August 30, 1994 with 37 subjects conveniently sampled from K & Y sports center located in Taejon. The 37 research subjects were assigned to experimental(16 subjects) and control(21 subjects) groups. Aerobic exercise was carried out for experimental group from three times to five times a week for 6 weeks in aerobic center. Data were analyzed with t-test, mean, per centage of change using SAS program. Results were obtained as follows: 1) Systolic blood pressure (M=123.75mmHg, % of change=1.12%) and diastolic blood pressure (M=74.38mmHg, % of change=5.79%) was increased on that of experimental group after 6 weeks experiment. But there was no significant difference between experimental group and control group. 2) Body weight was decreased on that of experimental group(M=56.54Kg, % of change=-1.60%) and that of control group(M=52.05, % of change=-0.99%) after 6 weeks. But there was no significant difference between experimental group and control group. 3) Body fat was decreased on that of experimental group(M=30.53%, % of change=-3.60%) and that of control group (M=28.75%, % of change=-3.52%) after 6 weeks. There was no significant difference between experimental group and control group. 4) Pulse rate was decreased on that of experimental group(M=69.19회/min, % of change -8.43%) and that of control group(M=76.0회/min, % change -0.07%) after 6weeks. There was significant difference(t=-2.621, P<0.05) between experimental group and control group. 5) Symptoms of stress response were decreased on that of experimental group(M=0.97) and that of control group(M=1.15) after 6 weeks. There was no significant difference between experimental group and control group. Therefore, adherence to aerobic exercise for 6 week seem to be affected mainly pulse rate of subjects. A futher study is necessary to determine the difference in the effect of variety exercise, programs, to study over 6 weeks, to produce professional educational program for exercise speciality nurses.

  • The purpose of this study is to develop a systematic and efficient curriculum for the rehabilitation nurse specialist program. This research was carried out as a group work of 15 experts in order to share various opinions about the curriculum, and also through literature review. Articles, curriculums of other Clinical Nurse Specialist Programs, medical laws guidelines, as well as Clinical Nurse Specialist Program from the Korean Nurses Association were reviewed, and the issue was discussed throughly via group meetings. The developed curriculum is as follows: 1. Educational philosophy lies in the fact that the rehabilitation nurses support the patients to maximize their potential and functional level, so that they could maintain healthy state and re-adapt to changed environment. Furthermore the rehabilitation nurses are disposed of arbitrary decision power under their own responsibility, thus they take charge of welfare and healthy environment of the local society through the patients(subjects) and local resources. 2. Educational goals are to train rehabilitation nurse specialist, who correspond to the social needs, so to say, those who have the knowledge and skills for nursing practice, education and research. 3. The curriculum consists of 37 credits, of which 24 credits are based on lectures and 13 credits based on clinical practice. General courses are 3 subjects (5 credits) ; nursing theory, nursing research, and laws/ethics. Mandatry courses are 8 subjects with 19 credits; advanced physical assessment, pharmacology, pathophysiology, issues in rehabilitation nursing, advanced rehabilitation nursing intervention I, advanced rehabilitation nursing intervention II, sports physiology, special rehabilitation nursing intervention. As for the clinical practice courses, assessment and evaluation for rehabilitation(64 hours), community and home based rehabilitation nursing(128 hours), hospital based rehabilitation nursing(128 hours), institution based rehabilitation nursing(96 hours) would be treated. 4. Contents of the curses were developed to correspond with the courses' objectives and specific items. 5. Evaluation would be carried out both in the lecture and in the clinical practice. The knowledge and skills of the students would be measured to ensure full validity and credibility. However this developed curriculum should be continuously modified and updated in more desirable direction.

  • Background and Objectives: Iodine is an essential constituent of the thyroid hormones associated with the growth and development of humans and animals as an inorganic nutrition. This element may be accumulated in human blood, tissues and body through the intake of foodstuffs, a beverage, a nutritional supplement and a medicine, among others. The aim of the research is to find out a better medicinal stuff for the thyroid cancer patient who required a low level of iodine diet. Methods: Neutron activation analysis (NAA) used for the iodine analysis is one of nuclear analytical techniques using radiation and radioisotopes and very useful as sensitive analytical technique for performing both qualitative and quantitative multi-elemental non-destructive analysis of major, minor and trace components in variety of environmental and biological materials. In this study, iodine contents in ten kinds of oriental herb medicinal products, which is frequently used to cancer patients are determined by using instrumental neutron activation analysis (INAA) at the HANARO research reactor. The samples prescribed are manufactured as powdered form for taking medicine easily. The analytical quality control is performed to assure an uncertainty of the measurement and to compensate the measured data using a biological certified reference material, NIST SRM 1572, Citrus Leaves. The measured value is $1.89{\pm}0.35mg/kg$, and the relative error is 2.88%, and relative standard deviation is 19 % due to high counting error by small counts of gamma ray spectrum. The standard deviations for other elements such as Cl, K, Mn and Na were in the range of 2 to 8%. Result: The level of iodine contents of Biki-huan, Chungryong-huan and Chungcho-huan, samples detected is less than 6 mg/kg except Hangam Plus sample (more than 210 mg/kg) and six samples were not detected. Iodine in the samples of Shoxiho-tang, Shopunghualhyl-tang, Shocungryong-tang, Banhasaxim-tang, Insampaedox-san and Myunyuk Plus were not measured, but possible level of content can be estimated from the detection limits. In addition, the concentrations of some major elements like Cl, K, Mn, Na, in the samples were determined with the detection limits. Conclusions: Most of samples showed low iodine contents of less than 6 mg/kg but it turned out that most of testing samples can be used to classify the level of iodine diet samples considering the recommended low level of iodine diet 50 ${\mu}g$/day, and a better medicinal stuff for the thyroid cancer patient can be found.

  • We performed a study to obtain kinematic data on the characteristics of spike serving techniques used by volleyball players, including other basic data that will be useful for in-field applications. We used three-dimensional videography to compare good tough serves and serve errors. The subjects were 3 left attackers whose spike serves were videographed (60 fileds/s). The three-dimensional coordinates were calculated using the direct linear transformation method and then analyzed using the Kwon 3D software program version 3.1. There was no difference in time elapsed. However, the vertical displacement of the center of body mass(CM) differed between the 2 types of serves: in successful serves, the CM tended to be lower, as did the maximum ball height at the time of hitting. Further, the higher the level of the hitting hand was at the moment of impact, the higher was the likelihood of scoring points. In good serves, the players tended to accelerate their CM movement just before jumping to hit the ball and descend rapidly at the moment of hitting. The hand speed along with ball velocity during the impact was proven to be higher in successful serves. Moreover, in successful serves, the shoulder angles increased to a greater extent while the elbow angles were maintained constant. This possibly resulted in faster and more precise serves. An important observation was that the angle of trunk inclination during the jump did not increase with the swing of the shoulders, muscle tendon complex.

  • In apparel industry, the production of clothing for the global market, has it#s origin in its characteristics depending on hands on working style, according to the globalization of a fashion industry. These days, however, the globalized production is unable to keep pace with the short cycle of production due to the unpredictable change of the taste or demands in the local area, as a result, the industry has come to take a focus on the production and consumption in the circumscribed region. In this stream, the northeastern area, specially, Dalian which is renowned for a center of fashion was designated as a city of this study as a representative. The cultural, racial and geographical uniqueness, asks for the analysis, based on the individual local area on the part of Korean fashion company desiring to launch into China fashion market. The purpose of this thesis is to analyse the style, color, and items of street fashion in Dalian. I would contribute to the understanding the preference of fashion in northeastern area, thereby, affording a fundamental resources for designing strategies for Korean fashion brands in China. The period of investigation is about 5 weeks from 14 May 2006 until 18 June 2006, with combined use of camcorder and digital camera. The site was Victory Shopping Plaza, in center of city, also with Mycal, Ansung, Dasang department store situated in the Economic Development area. The result of this study are as follows: 1. Preferred clothing styles are casual styles(68%) rather than formal styles(32%). In the casual styles, sports casual(36.0%), character casual(29.5%), jean casual(2.6%) were listed. All kinds of clothes are tightly fitted due to the stretched fabric and knit fabric. 2. Preferred colors are white(31.1%), red(16.6%), black(15.8%) khaki(7.8%) and blue(7.6%) for tops, and black(34.6%), blue(27.2%), white(15.4%), brown(14.6%) for bottoms. 3. Preferred clothing items are T-shirt(36.5%), jumper(33.6%), jacket(20.0%), blouse(8.7%), etc.(1.2%) for tops, pants(91.4%), skirts(8.6%) for bottoms. In the pants, cigarette pants(34.6%), bell bottom pants(21.0%), cargo pants(19.9%), straight pants(15.9%) were listed respectively.

  • Post-Environmental impact investigation(Post-EII) plays an important role in investigating and reducing the environmental impacts of construction operations in South Korea. To date, it has been estimated that the results for Post-EII showed the low reliability; however, understanding those reliability has rarely been studied. We investigated the effect on water qualities by construction operations of the quarry mine, training center, and golf club in South Korea. In addition, the results of water quality analysis in this study were compared and analyzed with those in Post-EII. Treated wastewater in a quarry mine showed high concentrations of biochemical oxygen demand(BOD), suspended solid(SS), total nitrogen(T-N), and total phosphorus(T-P). Compared with the water quality results between this study and Post-EII, the concentrations of BOD, SS, T-N, and T-P in the treated wastewater were higher than the interquartile range(IQR) as well as the range of the results from minimum to maximum in Post-EII(p<0.05). The concentrations of BOD, SS, T-N, and T-P in treated wastewater were high under constructions in a training center. The concentrations of BOD and SS exceeded the consultation standard for the treated wastewater. These concentrations showed the significant difference with the IQR and the range from minimum to maximum of the water quality results in Post-EII(p<0.05). Therefore, the management and monitoring for water quality should be conducted in the treated wastewater by of construction operations. In addition, the alternative to enhance the reliability for the water quality results should be sought in Post-EII.

  • Purpose : Conventional Balance Measurement can only measure the center of gravity and the shaking movement of the body. As a result, it has the disadvantages of not responding to visual changes and blocking functions of variables. This study was carried out to evaluate the performance of new equipment that measures the balance of the body using changes in body segment and pressure using the acceleration sensor to compensate for the disadvantages of the existing equipment. Methods : To this end, balance ability was measured in 43 healthy male/female adults without orthopedic injuries and nervous system damage in the last 6 months. in a situation where the visual information was restricted by Virtual Reality (VR) gear, all subjects measured and evaluated the balance ability utilizing the new equipment. Balance measurement (Prime Medilab, Korea) and Wii fit (Nintendo, Japan) were used to measure the balance ability of the subjects, and the balance ability test was performed in 4 postures using each device for data acquisition. The test duration for each posture was 30 seconds. For data acquisition, the average value of three experiments measured using each equipment was analyzed, and the statistical test was performed using the independent sample and the corresponding sample t-test, and the significance level was set to α=.05. Results : As a result of measuring the balance ability using individual equipment, blocking visual information using VR gear, the average speed, maximum speed, and moving area of the COP increased equally. It was found that the obtained absolute size of the result in Wii was somewhat larger than that of BM. Conclusion : It is considered that in the future research, it is necessary to measure changes in the body's center of gravity through image analysis, etc., to make clear comparison and evaluation of the usability.

By the comparison and the analysis of the different factors during the tennis flat serve motion such as the required time per section, the movement displacement of the racket, the velocity of the upper limbs joints, the physical center of gravity, and the angle and the angular velocity of the upper limbs joints between an ace player and a mediocre player, these following results were drawn. First, the experiment result of the total time required per section in a tennis flat serve motion showed that an ace player was faster than a mediocre player by 0.4 seconds. This result suggested that it was required to increase the speed of the racket head by a swift swing to perform an effective flat serve motion. Second, the experiment result of the movement displacement of the racket in the tennis flat serve motion showed that an ace player greatly moved toward the left side on an x-axis. But both an ace and a mediocre player were shown to be at the similar points on a y-axis at the moment of the impact of the racket. An ace player was also shown to be located at a higher position on a z-axis by 0.23m. Third, the velocity of the center of gravity of an ace player was faster in every phase than that of a mediocre player in a tennis flat serve motion. Fourth, the velocity of the upper limb joints of an ace player was faster in every phase than that of a mediocre player in a tennis flat serve motion. Fifth, the experiment result of the speed of the racket head in tennis flat serve motion showed that a mediocre player was faster than an ace player in the first phase, but the latter was faster than the former in the second, third, and the fourth phases. Sixth, at the moment of impact of a tennis flat serve, an ace player had greater flexion of the angle of the wrist joints by an 11.8 degree than a mediocre player. An ace player also had greater extension of the angle of the elbow joint and the shoulder joint respectively by a 5.2 degree and a 1.4 degree with a mediocre player. Seventh, an ace player had greater angular velocity of the upper limb joints and the hip joints than a mediocre player at the moment of the impact of tennis flat serve. Eighth, an ace player was shown to have a greater change of the forward and the backward inclination (or the anterior and posterior inclination) of the upper body
