Choi, K-J and Kwon, H-J. Sport biomechanical comparative analyses between general sporting shoe and functional walking shoe. Korean Journal of Sport Biomechanics, Vol. 13, No. 2, pp. 161-173. This study was performed to investigate the kinematic and kinetic differences between functional walking shoe(FWS) and general sports shoe(GSS). The subjects for this study were 4 male adults who had the walking pattern of rearfoot strike with normal feet. The movement of one lower leg was measured using force platform and 3 video cameras while the subjects walked at the velocity of 2/1.5 m/s. The findings of this study were as follows : 1. The angle of lower leg-ground and angle of knee with FWS was greater than with GSS at the moment of strike the floor and the moment of second peak ground reaction force. The decreasing rate of angle of ankle was smaller in FWS from the strike phase to the second peak ground reaction force. These mean upright walking and round walking along the shoe surface. 2. The maximal increased angle of Achilles tendon and the minimal decreased angle of rearfoot were smaller in FWS very significantly(p<0.001). Thus FWS prevent the excessive pronation of ankle and have good of rear-foot control. 3. The vertical ground reaction force and the rate of it to the BW were smaller in FWS statistically(p<0.001). The loading rate was smaller in FWS, too, and thess represent the reduction of load on ankle joint and prevention of injuries on it.

Seven cultivars of tomato were exposed to 0.15μL/L ozone for 20 hours to determine differences in sensitivity. Based upon the degree of foliar injury, the highest degree of sensitive cultivars were 'Daehyongboksu' and 'Goangsu'. Four cultivars, 'Goangmyong', 'Pungyoung' and 'Pinkglory' including 'Pinkforcer' were separated into intermediate sensitive group. 'Neabyongjangsu' was the least sensitive of the 7 tomato cultivars tested. The degrees of ethylene production and epinasty of leaves were relatively consistent with the differences of sensitivity to ozone. However, stomatal and trichome density, transpiration rate, and activities of peroxidase and superoxide dismutase were not clearly related to the ozone sensitivity of cultivars.

The purpose of this study is two-fold. One is to provide the teachers of Home Economics with the basic reference data ofthe relevance betwen Home Economics and other subjects taught in the middle schools for the purpose of bringing out more efficient classroom teaching. The other is to help the teachers, the textbook writers, and the curriculum reformers improve the curricula ofthe middle school on the basis of this research. The conclusions drawn from this study are as follows: 1) The units of Human development and Family Relationship should be teught with reference to Korean Language, Ethics, and Music. 2) The unit of Adolescence Development is dealt with in Physical Education and in Ethics as well, which seems to indicate that there was no interdisciplinary consideration and cooperation beefore/when the curricula were made. 3) The unit of Nutrition which appears in the first grade in Home Economics has a close second grade in Natural Science. It is thought that the interdisciplinary themes ought to be organized cooperatively among subjects for efficiency of study. 4) Since the unit of Clothing is not dealt with in the other subjects, it can be developed in Home Economics on its own. 5) As the unit of Housing is closely related to Teachnology, it should be taught on the basis of Technology. 6) The textbooks of all subjects should be written based on the interdisciplinary research and cooperation. They should be organized in order not to overlap or repeat the same topic in the same level if it is not necessary.

This paper focuses on the actual conditions of the local women's organization. These organizations are regarded as the best vehicle for improving women's status in local areas. However, the survey results of current situation of local women's organization reveals the organization is to a large extent in a very poor condition. The survey covered all the women's organization located in the six biggest cities and six seats of the provincial government. Among the 1,082 organizations, survey questionnaires were delivered to the 1,054 organizations, and 422 questionnaires were returned from August 23 to September 15 in 1999. 400 questionnaire were included in the field analysis. If we briefly examine the results, 78.0% of the organizations are "registered", 61.5% are "chapters of the Center", 74.5% are "members of the Women's Organization Council" and 16.0% are "member of the Women's Organization Union". The size of the organization varies from very small one having less than 30 members with only one person in charge to huge one having more than 10,000 members with 16 board members. And 59.8% of the organizations have no paid staff. In case of facilities, only 52.8% of these organizations have their own office, 56% have their own telephone number, 39.6% have a fax machine, and 36.2% own a computer. Only 28(7%) of these organizations have a homepage. In terms of working expenses, there is a great dispanity among these organization. 48.3% of the organizations spend less than 5 million won costs of operation. 95% of the organizations depend heavily upon their membership fees to manage the organization. The main purposes of these local women's organizations are as follows; 'Community development and volunteer work'(66.5%); The enhancement of 'women's status'(13.8%), The improvement in 'the quality and well-being of its members'(9.8%) and 'Cultivating mutual friendship'(4.3%) etc.. In the second part of this study the problems which is supposed to be experienced by most local women's organization are analyzed. For the convenience of this analysis, we have divided our analysis into four sections: First, among the organization-related problems, 'the lack of administrative and financial support'(mean value 3.29) was pointed out as the most serious problem, then 'the members' activities for the organization do not pay back'(mean value 2.88), and 'lack of independence and self regulation of the local women's organization'(mean value 2.63), and so forth. Second, in regards to problems of the membership and leadership, the style of 'leadership'(mean value 3.07) was recognized as the most difficult problem, followed by 'underestimation of the leader's activities'(mean value 3.04), and the burden of role playing by members'(mean value 2.82) was regarded as the third barrier to activate the local women's organization etc.. Third, in regards to problems relating to organizational activities & program-related issues, 'too much emphasis on the volunteer work' and 'the lack shortage of the program satisfying members' cultural needs'(mean value 3.01) are selected at the same time as the most urgent problem the organization needs to solve. Another problem was the 'lack of programs dedicated to the improvement women's status' and a 'lack of public relations vis-a-vis organizational activities'(mean value 2.97). Fourth, in the area of the other activities, the mean value(3.29) of 'the financial support increased' shows the highest, and 'the space for the women's activities should be secured'(mean value 3.06) shows the second highest. In order to activate these local women's organizations, "The organization should continue to make an effort'; "The government should offer administrative and financial support'; 'Gain understanding and cooperation firm family members as well as the local community', 'Gain social rewards in their organizational activities' etc. are suggested.

In order to examine the effect of the combination of fermented temperature and time on Baechu kimchi in a kimchi refrigerator, Baechu kimchi was fermented at four different modes of the fermentation temperature and time for 16 weeks and analyzed the properties of Baechu kimchi. The pH, Baechu kimchi fermented at 20℃ for 24 hours/stored at -1℃, decreased rapidly during first week and then decreased very slowly. The hardness and the chewiness of Baechu kimchi fermented at high temperature were higher and the values were decreased when the fermentation continued. In sensory evaluation, carbonated flavor in Baechu kimchi fermented at 20℃ for 24 hours/stored at -1℃ was the best after 4 weeks, and Baechu kimchi fermented at 5℃ for 3 days or 6 days/stored at -1℃ was the best after 8 weeks. The scores for sourness were the highest on 8 weeks and 12 weeks in kimchi fermented at 20℃ for 24hours/stored at -1℃ and 5℃ for 3 days or 6 days/stored at -1℃, respectively. Total microbial count was increased as the temperature of fermentation increased. Counts of Leuconostoc spp. reached to the highest after 6 days and counts of Lactobacillus spp. seached to the highest after 5 days in kimchi fermeted at 20℃ for 24 hours/stored at -1℃. From these results, it was concluded that it required 4 weeks to eat most edible Baechu kimchi in kimchi refrigerator 20℃ for 24 hours/stored at -1℃, and 8 weeks to eat edible Baeche kimchi refrigerator fermented at 5℃ for 3 days or 6 days/stored at -1℃.

Follicular lymphoma (FL) is the most common indolent or low-grade non-Hodgkin's lymphoma. Histologic transformation of high-grade lymphoma, generally to diffuse large B-cell lymphoma, occurs in 25-35% of cases. Although t(14;18), the cytogenetic hallmark of FL, has been found in ~85% of these cases, multiple secondary cytogenetic and molecular genetic changes underlie the transformation process We describe a case of follicular lymphoma with histologic documentation of transformation to Burkitt lymphoma within a single lymph node.

The purpose of present study was to identify the associated probelm behaviors of Attention-Deficit Hyperactivity Disorder (ADHD) children and to examine the differences in probelm behaviors across situation. The subjects of survey research consisted of 228 preschool children(147 boys and 136 girls aged from 3- to 7-year-old) drawn from five Child Care Centers in Chung-Ju. Data were analyzed by the frequency, percentages, Cronbach α coefficient, F-test, Tukey post-hoc test, and Pearson correlation using SAS program. The results were as followings: ADHD was highly correlated with externalized problem behaviors such as oppositional, immatural, and aggressive behaviors. It also was significantly associated with internalized problem behavior such as emotional instability. Correlations between ADHD and other problem behaviors were from .14 through .63. There were significant differences in problem behaviors across situation. Among groups, ADHD-School group was more likely to link to problem behaviors than other groups. Children of pervasive ADHD groups were more likely to have externalized behaviors than other groups.

목적 : 아단위 인플루엔자 백신 접종 후 백신의 인플루엔자 예방효과, 인플루엔자 방어 항체형성, 인플루엔자 백신의 안전성을 조사하고자 하였다. 방법 : 총 571명을 대상으로 인플루엔자 백신 접종을 하였고, 이들 접종자에서 인플루엔자 양질환의 이환을 조사하여 인플루엔자 백신의 인플루엔자예방효과를 알아보았고, 백신의 접종 전 및 접종 4주 후 혈청에서 혈구응집억제물(Hemagglutination Inhibition : HAI) 항체 검사를 실시하여 백신의 방어항체생성을 조사하였고, 백신의 안전성을 알아보기 위해 백신접종 후 1주일 이내의 부작용을 조사하였다. 결과 :백신 접종군과 백신 비접종군에서 인플루엔자 양 질환의 이환을 조사한 결과 접종군 28.35%, 비접종군 35.88%으로 나왔으며, p 값이 0.001로 통계적으로 접종군에서 유의하게 낮았고, 인플루엔자 양 질환의 예방 효과는 20.97%를 보였다. 백신의 방어항체 형성의 평가를 위해 유럽의 인플루엔자 백신 허가 기준을 조사하였는데 B/Guangdong/5/94균주의 백신접종 후 항체가 40이상의 비율을 제외한 다른 기준은 모두 만족 시켰다. 부작용은 전체 조사자 521명중 149명(29%)으로 주로 접종 부위의 국소 부작용을 호소했고, 전신 부작용은 2% 내외였으며 특별히 심각한 부작용은 발견되지 않았다. 결론 : 분편 인플루엔자 백신은 인플루엔자양질환의 예방과 방어항체생성에 효과 있으며 안전한 것으로 사료된다. Background : The safety and effectiveness of influenza vaccine are well known in developed country. The influenza vaccination has been recommended as one of the tentative immunization schedule for indicated persons since 1997 in Korea. But there are still no available data about them, even though nearly 5 million doses of influenza vaccine were used in 1997-1998 season. So it is immediately needed to investigate the safety. efficacy and immunogenicity of influenza vaccine among Korean. Methods : We studied the clinical efficacy of influenza vaccine by monitoring Occurrence of influenza-like illness in influenza risk group(vaccination ; 300, non-vaccination; 215) from December in 1997 to March in 1998. We used the split quadrivalent influenza vaccine containing 15 microgram of hemagglutinin of A/Beijing/262/95(HlNl), A/Wuhan/359/95(H3N2), B/Mie/1/93 and B/Guangdong/5/94. Hemagglutination inhibition(HA1) antibody titers were determined before immunization and 1 months after vaccination And we evaluated adverse effect of influenza vaccination at 7 days after vaccination. Results : Influenza vaccination was associated with si@icant reductions in influenza-like spptoms(vaccination group; 28.35%, non-vaccination group, 35.88%, p=0.001). The preventive effect of influenza-like i3lne.s among influenza risk goup was 20.97%. And immunogenicity of influenza A and B exceeded all of the European licensure criteria for immunogenicity except postvaccination proportion of titers 240 of B/Guangdong/5/94 strain. And the adverse effects were mainly local injection site problem and no serious adverse effect was noted. Conclusion : Split influenza vaccine is safe, inmunogenic and eff'tive in influenza risk group in Korea.
