본 연구는 콩나물의 물성에 미치는 콩나물 성장시 세포벽 다당류를 구성하고 있는 비섬유성 중성당의 변화를 조사하였다. 자엽부 세포벽의 중성당 조성은 rhamnose, fucose, arabinose, xylose, mannose, galactose, glucose 등이었고 주요 중성당은 galactose, arabinose, xylose 이었다. 배축부의 구성 중성당의 조성은 자엽부와 동일하였고, 성장함에 따라 대부분의 당이 감소하였고, 그 중에서도 galactose는 성장에 따라 현저히 감소하였으며, 성장 4일과 6일에는 오히려 galactose보다 arabinose 함량이 높았다. 배축부의 총 비섬유성 중성당 함량은 성장함에 따라 감소하였다. Pectin질의 중성당은 rhamnose가 CBP보다 IAP에서 많았고, galactose는 CBP에 많았으며, 성장함에 따라 IAP와 CBP의 arabinose는 자엽부와 배축부에서 다같이 증가하였다. Hemicellulose의 주용 중성당은 자엽부에서는 glucose, rhnmnose, galactose,xylose이었고 알칼리가용성 hemicellulose의 rhamnose 함량은 산가용성 hemicellulose에 비해 낮았으며, 성장중 galactose의 함량이 현저히 감소하였다. This study was carried out to changes and composition of the non-cellulosic neutral sugars in soybean sprouts during growth. The composition of non-cellulosic neutral sugars in cell wall of soybean sprouts were rhamnose, fucose, xylose, arabinose, mannose, galactose and glucose. The galactose contents of cell wall were higher than other non-cellulosic neutral sugars, and was remarkly decreased during growth. The major non-cellulosic sugars of pectic substances were rhamnose, arabinose, and galactose. The arabinose contents of pectic substance were increased in cotyledon and hypocotyl during growth. The contents of non-cellulosic neutral sugars were in hypocotyl during growth. The galactose contents of pectic substance were higher in cotyledon than those in hypocotyl associated pectic substances than those in covalently bounded pectic substances, arabinose and galactose. The galactose of hemicellulose was decreased remarkably during growth.

Ocjective : Sabaeksan has been used for the purpose of prevention and treatment of bronchial asthma and allergic asthma in korea. Methods : To investigate the biological effect of Sabaeksan, the author examined cytotoxicity and inflammatory cytokines secretion with human leukemic mast cell line, HMC-1. HMC-1 was stimulated with phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187. Sabaeksan by itself had no effect on viability of HMC-1. Result : The effects of Sabaeksan on the secretion of tumor necrosis factor-alpha (TNF-α) and interleukin (IL)-6 from HMC-1 were evaluated with enzyme-linked immunosorbent assay. Sabaeksan (1 mg/㎖) inhibited PMA plus A23187-stimulated TNF-α and IL-6 secretion, by 43.86 ± 5.26%, 56.39 ± 3.65%, respectively. Sabaeksan also inhibited the NF-κB (p50/p65) expression. Conclusion : Taken together, these results suggest that Sabaeksan inhibit the production of inflammatory cytokines in HMC-1 cells through blockade of NF-κB activation.

VPI occurs when the velum and lateral and posterior pharyngeal wall fail to separate the nasal cavity from the oral cavity during deglutition and speech. There are a number of congenital and acquired conditions which result in VPI. Congenital conditions include cleft palate, submucous cleft palate and cogenital insufficiency (CPI). Acquired conditions include carcinoma of the palate or pharynx and neurologic disorders. The speech characteristics of VPI is characterized by hypernasality, nasal air emission, decreased intraoral air pressure, increased nasal air flow, decreased intelligibility. VPI can be treated with various methods that include speech therapy, surgical procedures to reduce the velopharyngeal gap, speech aid prosthesis, and combination of surgery and prosthesis. This article describes four cases of VPI treated by speech aid prosthesis and speech therapy with satisfactory result.

이 연구는 컴퓨터 작업시 의자 등받이 위치가 근육활성도에 미치는 영향을 알아보기 위해 36명의 근골격에 문제가 없는 성인 남녀가 참가하였으며 대상자들은 등받이가 뒤에 있는 의자와 등받이가 없는 의자, 등받이가 앞에 있는 우리들 의자를 무작위로 배정하고 동일한 컴퓨터 작업을 실시하게 하였다. 실험 중, 표면근전도기를 사용하여 의자에 따른 위등세모근, 머리널판근 그리고 척주세움근의 근활성도 변화를 측정하였다. 이 연구의 결과를 종합해보면 등받이가 앞에 있는 의자는 허리 근육의 부담을 줄이지만 목근육에 부담이 늘어나고 등받이가 뒤에 있는 의자와 없는 의자는 허리근육에는 다소 무리가 가지만 목근육에는 부담이 덜하다는 것을 알 수 있었다. 이러한 결과로 환자의 증상에 다라 컴퓨터 작업을 하는 동안 의자 등받이의 위치를 조절하여 치료에 도움이 될 수 있다고 생각되어진다. Objective : In this study, we checked and observed people's change of body muscle and muscle activity who do computer work on different chairs. We set three kind of chairs which one is a stool and another one is the back is fixed, and the other one is the back is fixed in front of chair. Subject : Accounting for 36 health men and women, we divided these people to 3 groups and put them on the three cases(position 1, position 2, position 3). We measured muscle activity of upper trapezius, Splenius Cervics, Erector Spinae from the groups by using surface electromyogram system. Methods : The standard of the electromyogram was 'reference voluntary contraction', and we carried out 'one way anova' to compare muscle activity of three groups. Results : In position 1, reference voluntary contraction of upper trapezius muscle activity was 123.2821%, Splenius Cervics was 141.7526%, and Erector Spinae was 254.5233%. In position 2, reference voluntary contraction of upper trapezius muscle activity was 132.9395%, Splenius Cervics was 141.7526%, and Erector Spinae was 246.6540%. In position 3, reference voluntary contraction of upper trapezius muscle activity was 190.6487%, Splenius Cervics was 270.2332%, and Erector Spinae was 182.1021%. Both upper trapezius and Splenius Cervics muscle activity of position 3 group was higher than the others groups. In position 1 group, Erector Spinae muscle activity was hight than the other groups. And either was position 2 group's(p<0.05). Conclusion : Therefore the chair which is the back is fixed in front is more comfortable for waist muscle but it's not good for neck. And the other chairs are better in waist muscle but not in neck muscle. So far, when we do a computer work, it's prefer to sit on the group 1&2's chairs to reduce neck muscle's stress and sit on group 3's chair to reduce waist muscle's stress.
