The objective of this study consisted in manifesting on those couples who took part in the dance sport what effects the dance sport had upon their conjugal relations socially, emotionally, domestically, and athletically, and how these factors were on their practical life. For the purposed, 305 subjects were sampled out from those couples who were taking part in dance sport programs carried out by dance schools, the press, and local autonomous entities in the Seoul, Busan and Gyonggi areas of 2006. Among them 303 were finally taken as the real subjects with the exception of those respondents who were thought to have given insufficient responses. Date processing depended upon the SPSS ver 10.0 program, a frequency test was carried out along with a cross analysis on to identify significance among different group. Significance for analysis was based on the level of 5%. As a result of having conducted analysis, as stated above, a conclusion was derived, as follows. First, most of those couples who took part in the dance sport recognized that it was very good for their conjugal relations as leisure activities, expressed a higher satisfaction, as compared with other leisures activiteds. matrimonial complication at an early stage, but most of them did not think that it was a serious trouble after a period of continuous participation. Third, for the participant couples, the dance sport played a very positive role in enhancing the understanding of their conjugal reactions, showing a high satisfaction in considering the other party mutually. Fourth, the participant couples acknowledged that their couples came to take part in a wider range of social activities, along with the manifestation of positive responses from around themselves.

In response to that, maritime leisure sports may be considered as activities that are motivated inherently to help release many negative emotions and desires that people encounter in contemporary society. Therefore, this study is intended to investigate how the degree of participation of club members of maritime leisure sports(period, frequency, degree) influences the wellness index(physical health, mental healthy, social health, intellectual health, emotional health). In this study, members of maritime sports club in Busan city and Gyeongnam were selected as population, and 300 people were selected as the subject of this study by using purposeful sampling which is one of the non-probability sampling, were analyzed through computer program using SPSS/Win 17.0. The findings of this study indicated the followings: First, the period of participation, which is the sub-variables associated with the degree of participation, had a significant effect on all sub-variables of wellness index(physical health, social health, mental health, intellectual health, emotional health), and the effect was the highest in the group that participated for more than 8 years. Second, the frequency of participation, which is the sub-variable pertinent to the degree of participation, had a positive effect on all sub-variables of wellness index(physical health, social health, mental health, intellectual health, emotional health), and the effect was the highest in the group that participated for more than once a week. Third, the intensity of participation, which is the sub-variable relating to the degree of participation, had a positive effect on all sub-variables of wellness index(physical health, social health, mental health, intellectual health, emotional health), and the effect was the highest in the group that participated for more than 3 hours.

The purpose of this study is to examine the effects of the contraction strength of the lumbar extensor upon the kinetic variables on the upper limb joints in a scientific analysis. For this study, 4 Taekwondo athletes from B Univ. with advanced skills and a certain number of black belts from Korea Univ selected as the research subjects. The result of the research is as follows: 1. The total elapsed time of the movement was 0.288±0.028 seconds in the non-athlete group, while the athletes group shows a performance of 0.275±0.016 in the elapsed time for a movement. However, the time elapsed for the segmented events of a move did not show any statistically significant differences 2. For each event of a Momtong Jireugi (or a straight body blow), the joints in elbow, hip (coxa joint), and the knee did not show any significant differences except for in the angular displacements. Especially, the displacement at the hip joints showed statistically significant differences in MKA (p<0.05). Such differences appeared to be caused by the wider bending of the coxa joint of the athlete group compared to the non-athlete group, as the take-back of the left arm and torso was made bigger in the preparatory postures. 3. While taking a Momtong Jireugi move, the displacement of the linear movement per each event was analyzed, and the result showed a significant difference. The linear velocity of the right fist at E3 point of the athlete group was 3.17±0.17m/s, which was faster than 5.11±0.19m/s of the non-athlete group. 4. The analysis on the displacement of the linear acceleration in taking a Momtong Jireugi move also revealed a statistically significant difference. The linear accelerations of the right fist`s linear velocity at E3 were, respectively, 86.43±0.17deg/s(2) for the athlete group and 92.57±15.19deg/s(2) for the non-athlete group, making the athlete group significantly faster. 5. The displacements of the angular velocity and angular acceleration per each event during a Momtong Jireugi were also analyzed with a statistically significant result. The linear velocity of the angular acceleration at the right elbow joint was measured as 126.6±26.45deg/s(2), which was a significantly faster angular acceleration than those of other joints. 6. The muscular strength in the lumbar extensor of the athlete group was 149.80±57.61, while the nonathlete group measured 112.44±21.70, showing a statistically significant difference between the two groups (p<.002). Thus, in conducting a Jireugi move, the contraction of the lumbar extensor appeared to have impacts on the kinetic variables of the upper limbs. That is, in order for the Jireugi to gain more speed and accuracy, it is be- lieved that the torso should be fixed with the muscular tensions around the spine. In the following studies, we intend to examine the effects of muscular fortification training for the lumbar extensor upon the speed of the kicks and changes in the extensor.

이효연(Lee Hyo-Yeon) 한국체육과학회 2006 한국체육과학회지 Vol.15 No.4

The purpose of this study was to offer the basic data regarding the importance of Waltz's fundamental motion "Closed Change Step" to the dance sports club members and the students majoring in dance through the kinetic analysis. Each of 4 male and female subjects who were currently in action as amateur in sports dance field, and who won a prize in national, international competitions, were selected for this study, The angle variable, and 2 angle velocity variables were set for this experimental study, and 2 high speed cameras and 영상 analysis equipment were used. The variable gained from this experiment was computed by the average and the standard deviation. The result for this study was drawn below. First of all, the right shoulder angle by "the closed change step" motion on both men and women dancers increased gradually from E1(male: 166,16 / female: 149.17) to E3(male: 168.19 / female: 152.85), and maintained E1 angle(male: 166,16 / female: 149.17) from E49male: 163,15 / female: 148.93) to E6(male: 165,74 / female: 149.63). As a result, the right shoulder angle showed the minute motion at the "the closed change step. Second, the left shoulder angle by "the closed change step" motion on both men and women dancers showed the minute difference in the same as the right shoulder angle, but it showed the performance in the same shape with the right shoulder angle. The decrease of the left shoulder angle was initiated to E3(male: 151,44 / female: 158.62) due to the sway of body.

The release of genetically modified organisms ($GMO_{s}$) into the environment has the potential risks regarding the possibility of gene transfer from $GMO_{s}$ to natural organisms and this needs to be evaluated. This study was conducted to monitor the possible horizontal gene transfer from herbicide-resistant zoysiagrass (Zoysia japonica Steud.) to indigenous microorganisms. We have first examined the effect of field-released GM zoysiagrass on the microbial flora in the gut of locust (Locusts mlgratoria). The microbial flora was analyzed through determining the 165 rDHA sequences of microorganisms. The comparison of the microbial flora in the gut of locusts that were captured at the field of GM zoysiagrass and of wild-type revealed that there is no noticeable difference between these two groups. This result indicates that the GM zoysiagrass does not have negative impact on microbial flora in the gut of locust. We then investigated whether the horizontal gene transfer occurred from GM zoysiagrass to microbes in soil, rhizosphere and faecal pellets from locusts by utilizing molecular tools such as Southern hybridization and polymerase chain reaction (PCR). When the total DNAs isolated from microbes in GM zoysiagrass and in wild-type zoysiagrass fields were hybridized with probes for bar or hpt gene, no hybridization signal was detected from both field isolates, while the probes were hybridized with DNA from the positive control. Absence of these genes in the FNAs of soil microorganisms as well as microbes in the gut of locust was further confirmed by PCR. Taken together, our data showed that horizontal gene transfer did not occur in this system. These results further indicate that frequencies of transfer of engineered plant DNA to bacteria are likely to be negligible.

청소년과 그들의 보호자를 대상으로 실시한 A형 간염 예방접종에 대한 지식 및 건강신념 연구

윤서희,이효연,김한울,공경애,김경효,Yoon, Seo Hee,Lee, Hyo Yeon,Kim, Han Wool,Kong, Kyoung Ae,Kim, Kyung-Hyo 대한소아감염학회 2013 Pediatric Infection and Vaccine Vol.20 No.3

목적: 최근 과거에 비해 A형 간염 발생률이 감소하고 있으나, 예방접종 도입 이전에 출생한 청소년들은 A형 간염의 대량발생 위험성이 있다. 본 연구는 A형 간염 예방접종을 시행하지 않은 청소년과 그 부모를 대상으로 A형 간염 예방접종에 대한 지식과 건강신념을 조사하였다. 방법: 만 13-19세의 A형 간염 과거력이 없고 예방접종을 시행하지 않은 건강한 청소년들과 그들의 보호자들을 대상으로 건강신념모델에 근거한 구조화된 설문지를 통해 조사를 실시하였다. 설문조사는 대상자들의 일반적 특성과 A형 간염 및 A형 간염 예방접종에 대한 지식과 건강신념을 조사하였고, 건강신념은 민감성, 심각성, 유익성, 장애성의 4가지 항목으로 측정하였다. 결과: 총 314명(157쌍)의 청소년과 보호자들이 모집되었고, 청소년과 보호자의 평균 나이는 각각 $16.0{\pm}1.6$, $45.6{\pm}4.7$세였다. 대상자의 A형 간염 및 예방접종에 대한 지식점수는 청소년, 보호자 각각 18점 만점에 평균 $6.4{\pm}3.7$점, $7.3{\pm}3.4$점이었으며, A형 간염과 예방접종에 관한 건강신념 세부항목들의 평균점수는 청소년과 보호자 각각 다음과 같았다. 민감성 점수(점수범위: 2-10점)는 $5.6{\pm}1.6$점과 $5.9{\pm}1.7$점; 심각성 점수(점수범위: 5-25점)는 $16.3{\pm}4.1$점과 $18.3{\pm}3.6$점; 유익성 점수(점수범위: 5-25점)는 $19.7{\pm}3.3$점과 $20.6{\pm}2.1$점; 장애성 점수(점수범위: 17-85점)는 $41.3{\pm}8.9$점과 $39.0{\pm}9.1$점이었다. A형 간염 예방접종을 시행하지 않은 가장 주된 원인은 청소년과 보호자 모두 'A형 간염 예방접종을 해야한다는 것을 알지 못했다'를 가장 많이 선택하였다. 결론: 청소년층의 A형 간염 대유행의 위험을 낮추고 접종률을 높이는 방안으로서 보호자가 함께 참여하는 반복적인 학교 보건교육이 필요하며, A형 간염 예방접종의 국가필수예방접종 도입도 고려되어야 하겠다. Purpose: Although the overall incidence of hepatitis A in Korea has been decreasing recently, the adolescents born before the introduction of the hepatitis A vaccine remain to be highly vulnerable to outbreak. This study examines the unvaccinated adolescents' and their parents' knowledge and health beliefs toward hepatitis A vaccination. Methods: Healthy adolescents aged 13-19 years old who had no previous history of hepatitis A vaccine and hepatitis A infection, and their parents or legal guardians were the subjects of the study. The survey was conducted using a structured questionnaire based on the Health Belief Model, and examined the subjects' demographics, knowledge, and health beliefs (i.e., perceived susceptibility, severity, benefits, and barriers). Results: We included 157 adolescents and their parents/guardians (mean age: $16.0{\pm}1.6$ and $45.6{\pm}4.7$ years, respectively). The average knowledge item score for adolescents and parents was $6.4{\pm}3.7$ and $7.3{\pm}3.4$ (out of 18), respectively. Similarly, average Health Belief Model item scores were: susceptibility, $5.6{\pm}1.6$ and $5.9{\pm}1.7$ (range: 2-10); severity, $16.3{\pm}4.1$ and $18.3{\pm}3.6$ (range:5-25); benefits, $19.7{\pm}3.3$ and $20.6{\pm}2.1$ (range:5-25); and barriers, $41.3{\pm}8.9$ and $39.0{\pm}9.1$ (range:7-85). The major reason for not undergoing hepatitis A vaccination was lack of knowledge about its importance. Conclusions: Refresher health lectures about hepatitis A and the vaccine are needed by both the adolescents and their parents. Furthermore, the inclusion of hepatitis A vaccine in the national immunization program should be considered to reduce the risk of hepatitis A outbreak and to raise the vaccination coverage among the adolescents in Korea.

In gametophytic self-incompatibility, pollen tubes expressing S-alleles identical to those expressed in the style cease growth in the upper third of the style. The S-allele products of pollen and discriminate between self and cross-pollen. S-allele-associated pistil proteins(S-glycoproteins) have been identified in many Solanaceae. The sequences of a number of Solanaceous S-glycoprotein have been deduced from the corressponding cDNA sequences and compared their primary structure between them. The biological function of S-glycoproteins in the self-incompatibility interactions has not been demonstrated. S-glycoproteins corresponding to the most S-alleles isolated from style extracts of Nicotiana, Petunia, Solanum has a ribonuclease(RNase) activity. But the arrest of pollen tube growth was not simply explained by RNase action, and transcription and glycosylation process is necessary for the expression of self-incompatibility, plural genes or action sites may be involved in an S-gene. There are some unresolved question in RNase hypothesis ; How can be explain S-allele specificity? What is substrate of RNase? What is self-incompatibility related substance in pollen side against style side? Anyhow, at the moment, differences between gametophytic and sporophytic systems are clear, and we are inevitably believe that plants having different structure of flower have obtained respective systems to secure the genetic heteroveneity in the course of evolution.
