The purpose of this study was to compare kinematics of the skilled group with the corresponding of the unskilled group during the leap of the mordern dance and to investigate the effective movement patterns of the leap. The kinematic and temporal variables examined using the DLT(Direct Linear Transformation) method of three-dimensional cinematography were leap time, leap distance, leap height and body segment angles at the instants of take off, peak height and touch down. Four skilled and four unskilled groups were selected as the subjects. Two 16mm high speed cameras were used to monitor the subjects’movement patterns. T-test was used to determine if there is any significant (p<0.05) differences on kinematic variables between the skilled and unskilled groups. The conclusions obtained from the analyzed data were as follows; (1) There were not any significant differences between two groups for the angles of body segment at the instant of take off and leap distance. (2) At the instant of peak height, the leap angle and the left ankle angle for the skilled groups were larger than for unskilled groups. (3) At the instant of touch down, the trunk angle in the sagittal plane for the skilled groups were larger than for unskilled groups. (4) The flight time and height for the skilled groups were longer and higher than for the unskilled groups.

We have studied on the curriculum to develop the communication department of the inter-related fisheries and marine junior college groups and abridged them as follows. (1) A vessel communication has the special characteristics compared with general communication field and also it has an aim to protect the lives and the property from dangerous navigation. For these reasons we must educate many competent graduates who are versed in business and accustom themselves to necessary knowledge of communication and can be adapted them selves to the advanced communication method, techniques and international information on the communication. (2) Training goal and way of thinking of students were rearranged and the occupational cluster in the electronic-communication field was fractionated to develop the curriculum. Especially regarding operator's duty served the above purpose as a occupational cluster, we analyzed their job in accordance with it. (3) International convention on standards of training certification and watchkeeping for seafarers, 1978 was reflected, also international telecommunication convention was referred so that it might be satisfied with the condition to be observed. (4) Developing the curriculum, we responed and analyzed the questions from scientific world, industrial organizations and graduates and provide their advice and suggestions form consultive committee and reflected them to develop the curriculum

It is reported that alcohol drinking by pregnant mothers often leads to abnormal fetal development including fetal alcohol syndrome(FAS) in both humans and experimental animals. The FAS is characterized by prenatal and postnatal growth retardation, distinct craniofacial dysmorphology, and central nervous system dysfunctions such as mental retardation. However, molecular mechanisms for FAS is not completely elucidated as yet. In this study, developmental toxicity of ethanol and its metabolite, acetaldehyde were evaluated using whole embryo culture. In addition genes inducing FAS were investigated by the technique of cDNA microarray. Embryos treated with ethanol showed growth retardation, abnormal tail torsion, open neural tube, open caudal neural tube and abnormal somite at concentrations of 0.1∼0.5%. Also embryos treated with acetaldehyde showed growth retardation including allantois, open caudal neural tube, reduction number of somite and abnormal tail torsion at concertrations of 5×10^(-4)∼2.5×10^(-3)%. RNAs from embryos of control and ethanol treatment were reverse transcribed into cDNA tagged with Cy3 or Cy5 and hybridized with cDNA probe of rat in 'toxicology chip'. Ethanol 0.5% treatment resulted in alteration in expression of several genes including 'serum deprivation response', 'Cide-b' and 'check point suppressor 1'. Northern blot analysis is conducted for identification of genes related to FAS.

이 연구는 트레드밀 운동과 키네시오 테이핑의 효과에 따른 폐활량의 변화를 알아보기 위해 26명의 비흡연자가 참가하였으며 키네시오 테이핑을 적용하지 않은 그룹과 키네시오 테이핑을 적용한 두 그룹으로 무작위로 배정하고 각 군들을 주 3회 6주간의 트레드밀 훈련을 실시하였다. 실험 전과 후, 스파이로미터를 사용하여 키네시오 테이핑의 적용 따른 폐활량 변화 효과를 측정하였다. 이 연구의 결과를 종합해보면 키네시오 테이핑을 적용 그룹에서 적용하지 않은 그룹에 비해 FVC, FEV1에서 유의한 증가를 보였다. 이러한 결과는 건강한 성인에서 키네시오 테이핑을 적용한 경우 키네시오 테이핑을 적용하지 않고 트레드밀 운동을 한 경우보다 폐활량의 향상에 효과적이라고 생각되어진다. The purpose of this study was to investigate the variation of vital capacity(VC) according to the effects of kinesio taping with treadmill exercise. Twenty-six non-smokers were participated in this research and these subjects were randomly assigned into two groups. To measure the VC variation effects of kinesio taping, spirometer was used. The collected data were analyzed statistically by using a paired Mauchly test and repeated measure ANOVA. The results of this study were as follows; A group: treadmill with kinesio taping B group: treadmill without kinesio taping. Between A and B, there were significant differences. In the case of A group, there was 11.66% increase of VC, during 3 weeks experiment(p<.01). In the case of B group, there were significant differences, 3.35% increase of VC, during 3 weeks taping intervention(p<.01). After 6 weeks experiment, the improvement of VC shown a significant difference with intergroup (p<.05). From this result, it was revealed that treadmill exercise with kinesio taping was effective to improve VC to healthy adult than treadmill exercise without kinesio taping.

Effects of salt concentration and C/N ratio on pollutants removal efficiencies were investigated in treatment of seafood wastewater by sequence batch reactor(SBR). The synthetic seafood wastewater containing salinity from 3,000 to 10,000 mg/L NaCI and C/N ratio of 2 and 4 was treated by SBR. Removal efficiencies of COD_(Mn), T-N, and T-P decreased with increasing salt concentration, but eventually reached a pollutants removal a platrau. As systems adapted in salts until salts concentration of 8,000mg/L, the time required to reach the pollutants removal efficiencies at steady state was reduced. However, the removal efficiencies of pollutants sharply decreased and the time require to reach steady state was increased as salt concentration rose to 10,000mg/L, Removal efficiencies of COD_(Mn) were higher for C/N ratio of 4 than for 2. Effects of salt on the nitrogen removal were not faster than the organic removal but the time required to the nitrogen removal at steady state was ncreased. The removal efficiencies of phosphorus also were redueed as salt concentration increased, which inhibited the release of phosphorus than the uptake.
