The purpose of the present study was to investigate the relationship between isokinetic muscle function and muscle cross-sectional area (CSA). Twelve women participated in the present study, divided young (n=6, 23.7±1.9 year) and elderly women (n=6, 60.3±6.8 year). Isokinetic strength (power, strength, endurance) and CSA (psoas major and thigh muscles) measured with dynamometer and computerized tomograph, respectively. Cross-sectional area of psoas major muscle in elderly group revealed markedly smaller than in young group, but thigh muscle was not the case. Muscle CSA in young women correlated between power and endurance and psoas major muscle, as well as between muscle strength and CSA of thigh muscle. But no correlation occurred between strength and cross sectional area, except endurance which was highly correlated between CSA and endurance. In conclusion, aging decreases muscle function and CSA. Partially muscle strength correlated with muscle CSA in young women, but no correlation occurred in elderly women. Further study needed to elucidate the exact mechanism related to aging muscle with muscle density and neuromuscular function.

Structures, Nanomechanics, and Disintegration of Single-Wall GaN Nanotubes: Atomistic Simulations

Jeong Won Kang,황호정,Jun-Ha Lee,Ki OH Song,Ki Ryang Byun,Oh-Keun Kwon,Won Young Choi 한국물리학회 2003 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.43 No.I

We have investigated the structural, mechanical, and thermal properties of single-walled GaN nanotubes by using atomistic simulations and a Tersoff-type potential. The Tersoff potential for GaN eectively describes the properties of GaN nanotubes. The nanomechanics of GaN nanotubes under tensile and compressive loadings have also been investigated, and Young's modulus has been calculated. The caloric curves of single-walled GaN nanotubes can be divided into three regions corresponding to nanotubes, the disintegrating range, and vapor. Since the stability or the stiness of a tube decreases with increasing curving sheet-to-tube strain energy, the disintegration temperatures of GaN nanotubes are closely related to the curving sheet-to-tube strain energy.

In this paper. the Γ type eqivalent circuit is used to analyze the steady state characteristics of induction motor driven by inverter source. The base tests for equivalent circuit parameters of induction motor are a no-load test by rated frequency (60Hz) and a blocked rotor test by 25% of rated frequency (15Hz) which are perfomed with inverter source. and measurement of the de resistance of the stator winding. To determine more accurate parameters, four simultaneous equations obtained from equivalent circuit of the no-load test and blocked rotor test are solved by using initial values which are evaluated from simplifed equivalent circuits. The induction motor performances are computed by using these parameters and compared with measured values of the tested motor. Then it is found that the compared results show good agreement between them.

SBCD(School Based Curriculum Development)에 따른 교육과정 개발 방법의 고찰

정영근 한국교육과정학회 2000 교육과정연구 Vol.18 No.2

본 연구의 목적은 교육과정 개발이 갖는 역동성에 주목하여 SBCD의 특성을 검토하고 학교 수준에서 교육과정을 개발하는 데 필요한 방법에 대해서 고찰하는 데 있다. 여기서 말하는 방법이란 특정 교육과정 개발의 목적 및 의도를 달성하기 위한 수단과 그것을 실시하는 절차 및 기술을 말하는 것이다. 본 연구자는 SBCD에 대한 당위론적 주장을 극복하기 위해서는 방법적 논의가 필요하다고 보고, 교육과정 개발의 역동성이라는 측면에서 SBCD에 따른 교육과정 개발 방법에 대해서 고찰하여 우리나라 학교교육 상황에서 그 실천가능성과 문제점을 검토해 보고자 한다. 이와 같은 연구목적에서 이루어진 고찰을 바탕으로 보면, 먼저 SBCD는 각 학교의 현실에 맞는 교육과정 개발에 목적 및 의도를 두고 60년대의 RDD에 따른 국가 수준의 교육과정 개발의 대안으로 OECD가입국을 중심으로 하여 70년대에 등장한 것임을 알 수 있다. 그러나 SBCD에 따른 교육과정 개발의 방법은 단순히 학교에만 한정시키는 것이 아니라, 그 국가의 사회·문화적 특성에 따라 형성된 전체적인 교육 시스템 하에서 논의되어야 한다고 생각한다. SBCD의 목적 및 의도를 달성하기 위한 방법은 종래의 교육과정 패캐지 또는 자료, 문서작성과 같은 활동에서 벗어나 역동적 교육과정 개발관을 필요로 한다. 왜냐하면 SBCD가 갖는 상호작용적 특성 때문이다. 즉 국가 교육과정과 SBCD간 및 교사를 중심으로 한 참가자들간, 개발단계간, 개발에 다른 교육과정 구성요서간의 상호작용이 이루어진다는 것이다. 이러한 상호작용은 교육과정 개발의 역동성을 유지·지속시키는 원천이 된다. 본 연구에서는 이것을 위해서 '수업상황을 기반으로 한 교육과정 개발'과 '상황분석을 기반으로 한 교육과정 개발', '교육과정 개발의 지원 시스템의 구축을 제시하고 있다. 또한 SBCD에 따른 교육과정 개발에서 교사에게 요구되는 전문성의 하나로 '상황분석의 역량'을 제안하고 있다. The purposes of this study are examining; 1) the characteristics of the SBCD by considering the dynamism of curriculum development, and 2) the method for curriculum development in school level. The method includes means for achieving the purpose of a curriculum development, and process and skill for implementing the curriculum in this study. This study consists of four main topics for the purposes, which are 1) the dynamism of curriculum development, 2) the change of curriculum development theory by the SBCD, 3) the point of dispute in the method of curriculum development of the SBCD, and 4) the framework of the SBCD. According to the study, it is proved that the SBCD appeared for curriculum development by each school in the 1970s mainly from the OECD members instead of using national curriculum in the 1960s. However, the relationship between the SBCD and the national curriculum is interdependent. So that the method of curriculum development of the SBCD should consider both each school situation and education system formed by social and cultural characteristics of the country. To achieve the purpose and intention of the SBCD, it is necessary to have a view of dynamic curriculum development because the SBCD has an interdependent relationship with the national curriculum. According to the dynamic curriculum development, there is interaction not only between the national curriculum and the SBCD but also within curriculum development steps, participants and curriculum elements. This interaction keeps the dynamism of curriculum development. This study shows 'curriculum development based on class situation', 'curriculum development based on situation analysis', 'construction of supporting system for curriculum development' and 'support system of curriculum development'. And this study suggested capability of situation analysis as a teacher's professionalism for curriculum development.

이재영,윤성호,서유진,최정희,서창희,남동호,김윤근,민경업,박해심 대한천식 및 알레르기학회 2004 천식 및 알레르기 Vol.24 No.1

Background : The common whelk (Buccinum undatum) is one of the largest and most common snails in the North Atlantic. In Korea and Japan, common whelk is a popular eatable shellfish. Although shellfish has been known as the one of the most common causes of food allergy, there has been no published report on allergenecity and clinical significance of this sea snail. In this study, we determined the sensitization rate to common whelk and its relationship with other food allergens in allergy patients. Method : We carried out the skin prick test (SPT) with commonly consumed food stuffs in Korea including common whelk in 1700 patients over 1 year. The specific IgE to common whelk were detected by enzyme-linked immunosorbent assay (ELISA). ELISA inhibition test using sensitized sera was conducted. Results : SPT to common whelk was positive (≥2+) in 83 (4.9%) patients studied. Twenty-four (38.7%) of 62 SPT-positive patients had high serum specific IgE to common whelk. ELISA inhibition test showed significant inhibitions by abalone as well as by common whelk and, minimal inhibition were noted by shrimp. Significant correlation was also noted in specific IgE levels between common whelk and abalone (r=0.58, F<.05). Conclusion : IgE-sensitization rate to common whelk was 4.9% in allergy patients. Further stuides are needed to evaluate the clinical significance of sensitized patients to common whelk, and to confirm a cross reactivity with abalone. (J Asthma Allergy Immunol 24 : 77-84, 2004)

Ankylosing Spondylitis is a chronic progressive inflammatory disorder of unknown etiology involving principally the axial joints of the spine, chiefly the sacro-iliac apophyseal and costovertebral articulations resulting in not only deformity but also functional disability in terms of cardiopulmonary dysfunction and activities of daily living. The purpose of this study is to find out the effects of the therapeutic massage applied to the patients with Ankylosing Spondylitis by measuring, assessing and analyzing the changes muscle pains before and after Patient Education and Therapeutic Massage. In the therapeutic massage program, such methods as effleurage, petrissage and deep transverse friction were selected as traditional massage treatments frequently used for muscles with pain and spasticity. Effleurage and petrissage were applied for 20 minutes in total before and after deep transverse friction treatment. We assessed the effects of patient education and therapeutic massage in ankylosing spondylitis. The subjects of this study were 23 patients with confirmed ankylosing spondylitis by New York criteria who had visited J Sports Massage Clinic from January, 2001 to August, 2002. We have made two sessions of patient education and therapeutic massage for 4 weeks. The major findings from this study are as follows; 1. There were significant improvements in pain, nocturnal awakenings, morning stiffness, functional status, forward flexion of trunk, and lateral flexion of trunk. 2. The treatment outcomes were poor as the disease duration increase. 3. There was significant decrease in the numerical values of VAS, VRS and MPQWL after Therapeutic massage(p<.05). 4. There was significant decrease in the intensity and unpleasantness of pains after Therapeutic massage(p<.05). 5. From the analysis into chronological changes in the intensity and unpleasantness of pains before and after Therapeutic massage with ANOVA, it became evident that the longer the period of treatment was, the higher the pains decreases drastically, while significant difference was shown in the intensity and unpleasantness of pains(p<.05). Summed up, it can be generally concluded that Patient Education and Therapeutic Massage is an effective treatment to rid the patients with Ankylosing Spondylitis of pains safely and promptly.

진상근,김일석,송영민,허선진,박기훈,정기종,김동훈,노정만 진주산업대학교 산업과학기술연구소 2006 산업과학기술연구소보 Vol.- No.13

Berkshire를 이용하여 70일간 산삼 배양액 급여 시 육의 이화학적 특성에 미치는 영향은 다음과 같다. 산삼 배양액의 급여에 의해 육의 수분, 조단백, 조지방, 회분, pH, 가열감량, 콜레스테롤 함량, 육색, 조직감의 응집성과 검성, 포화지방산 및 불포화지방산의 비율은 차이를 보이지 않았다. 보수력, 지방색 L^(*)값, 지방산 중 linoleic acid(18:2), arachidonic acid(20:4), 필수지방산의 함량, 아미노산 중 threonine, glutamic acid, valine, isoleucine, leucine, histidine, lysine 및 총아미노산 함량은 산삼 배양액의 급여에 의해 감소하였다. 전단가, 조직감의 표면경도, 경도, 씹힘성, 지방산 중 stearic acid(18:0), oleic acid(18:1) 함량, 아미노산 중 serine, glycine, cystine, methionine, tyrosine 및 phenylalanine의 함량은 산삼 배양액의 급여에 의해 증가하였다. 본 연구결과를 종합하면 산삼 배양액의 급여는 돈육의 경도를 증가시키는 효과 외에 뚜렷한 이화학적인 차이를 나타내지 않았다. 이러한 이유는 급여된 산삼 배양액 내에 함유된 생리활성 물질의 함량이 낮고, 급여수준이 낮은 결과로 사료되어진다. A total of 60 pigs (Berkshire) were used to investigate the effect of dietary artificial culture medium of wild ginsengs (CMG) on physico-chemical characteristics of pork. About 60 kg pigs were randomly alloted into one of two experimental diet groups (C:commercial diet feed; T:commercial diet + 1 L CMG per day for 70days). Pigs were slaughtered at approximately 110 kg live weight, and chemical composition and physico-chemical characteristics were measured in pork loin. Moisture, crude protein, crude fat and ash were not significantly different by dietary artificial culture medium of wild ginsengs. Water-holding capacity was decreased by dietary artificial culture medium of wild ginsengs, while shear force was increased. However, pH, cooking loss and cholesterol contents were not significantly different between two different treatments. In color, L^(*) of fat was decreased by dietary artificial culture medium of wild ginsengs. Brittleness, hardness and chewiness were increased in dietary artificial culture medium of wild ginsengs group. In fatty acid, stearic acid (18:0) and oleic acid (18:1) were higher in dietary artificial culture medium of wild ginsengs group, whereas linoleic acid (18:2) and arachidonic acid (20:4) were higher in control group. In amino acid, serine, glycine, cystine, methionine, tyrosine and phenylalanine were higher in dietary artificial culture medium of wild ginsengs group, whereas threonine, glutamic acid, valine, isoleucine, leucine, histidine and lysine were higher in control group.
