The Purpose of this study was to investigate the peer acceptance of mainstreamed students with mild disabilities in elementary schools. To assess peer acceptance, A sociometric scale was group-administrered to each student of participating 55 classes(grade 2-6). The peer status and peer acceptance of 459 nondisabled students and 55 disabled students were examined and compared. The relationship between teacher preference ratings of disabled students and sociometric ratings was explored. Compared to nondisabled students, more mainstreamed disabled students were rejected and isolated and fewer were popular. Disabled rejected students were more rejected and less acceptance of 459 nondisabled students and 55 disabled students were examined and compared. The relationship between teacher preference ratings of disabled students and sociometric ratings was explored Compared to nondisabled students, more mainstreamed disabled students were rejected and isolated and fewer were popuar. Disabled rejected students were more rejected and less accepted than nondisabled rejected students. Three quarters of disabled students were nominated as victims of bullying. Teacher preference scores for disabled students were not related to peer acceptance.

The purpose of this study was to investigate the influence of the various knee angles and ground state on the muscular activities and fatigue of the ankle muscles by integrated electromyograms (iEMG) and median frequency of tibialis anterior (TA), peroneus longus (PL), flexor digitorum longus (FDL) and gastrocnemius (GC). Ten healthy male subjects were participated into stable and balance ball sessions at four angles of knee joint. The surface electromyograms (sEMG) were recorded from the TA, PL, FDL and GC on stable and balance ball with full weight bearing at four knee angles of 0˚, 15˚, 30˚ and 45˚. The time serial data of the surface electromyographic signals were transformed into integrated and frequency serial data by fast fourier transformation. On the stable ground, the iEMG signals of the TA, PL, FDL and GC were significantly higher at 45˚ and 30˚ of knee angles than 0˚ and 15˚ of knee flexion (p<0.05). On the balance ball, the iEMG of the TA, PL, FDL and GC were significantly higher at 45˚ and 30˚ of knee angles than 0˚ and 15˚of knee flexion (p<0.05). The median frequency of the TA, PL, FDL and GC were significantly lower at 45˚ and 30˚ of knee angles than 0˚ and 15˚ of knee on the stable ground (p<0.05). On the balance ball, also the median frequency of the TA, PL, FDL and GC were significantly lower at 45˚ and 30˚ of knee angles than 0˚ and 15˚ of knee flexion (p<0.05). The iEMG of the TA, PL, FDL and GC were significantly higher on the balance ball at 0˚, 15˚, 30˚ and 45˚ of knee angles compared with stable ground. The median frequency of the TA, PL, FDL and GC were significantly lower on the balance ball at 0˚, 15˚, 30˚ and 45˚ of knee angles compared with stable ground. These results indicate that the ground conditions and angles of the knee joint involved to muscular activities and fatigue of ankles muscles, may performed at first on stable ground and then balance ball in order to 0˚, 15˚, 30˚ and 45˚ of knee flexion.

Abstract – Aberrant crypt foci (ACF) are early imorphological changes observed in rodents after administration of colon-specific carcinogen such as azoxymethane (AOM). ACF are considered to be putative preneoplastic lesions and are widely used as a surrogate biomarker to rapidly evaluate chemopreventive potential of compounds. The size of colorectal cancer was evaluated after administration of three anticancer drugs, 1 parent drug and 2 prodrugs. The body weights of mice were measured daily and considered as a surrogate for evaluation of general wellbeing. Colons were removed, cut along the longitudinal axis and flushed with phosphate-buffered saline. Each colon was cut into three equal lengths and fixed flat between filter papers. The fixed colon sections were stained with methylene blue. The number of ACF per colon, the number of aberrant crypts observed in each focus and the location of each focus were recorded. After single administration of AOM and multiple doses of anticancer drugs, no significant changes in the body weights of the mice was observed which was recorded for 52 days. However, an expected ACF was not observed in any treated groups. These findings suggest the induction of ACF in mice requires the promotion by dextran sulfate sodium as well as the initiation by AOM.

본 논문은 발달장애유아 언어행동발달 컨텐츠 개발에 요구되는 기초연구로써 연구의 이론적 바탕을 확립하고자 하였다. 연구에 사용된 방법은 문헌조사 방법 및 현장 인터뷰기법을 병행하였다. 본 연구의 주된 목적은 크게 3가지로 구분된다. 첫째, 발달장애유아의 가정 내 교육 욕구를 분석하고자 하였다. 둘째, 발달장애유아의 언어발달 양상을 검토하고자 하였다. 세 번째 목적은 유아의 언어행동발달 컨텐츠 구성의 주요 지침을 설정하고자 하였다. 이상의 연구목적에 따른 연구결과를 요약하면 다음 몇 가지로 제시된다. 1.가정 내 부모-유아간 관계형성이 우선 고려 되어야하고, 이에 따른 상호작용은 발달적 애착형성이 가능한 방향으로 정립되어야한다. 2.발달장애유아의 언어행동발달양상을 검토한 결과에 따르면, Piaget는 언어행동발달에 있어 감각운동기적 환경탐색 기능을 강조하고 있고, 이는 현재까지 중요한 유아 발달의 기저로 정착되었다. 따라서, 발달장애유아의 언어행동발달을 위한 컨텐츠 개발 내용에 있어서도 이러한 기저에 충실함이 합리적이다. 3.발달장애유아들에게는 언어행동 양상의 갈래가 크게 운동장애 및 감각결함으로 나누어질 수 있으므로, 이 두 가지 갈래의 각기 다른 특성이 컨텐츠 구성에서 충분히 고려되어야한다. 4.자폐성과 같은 중증 전반적 발달장애 유아를 위한 언어행동발달 컨텐츠 구성에서 특히 고려해야 할 두 가지 요소는 모방행동기능과 반복단순훈련기능 향상으로 결론지을 수 있다. This article planed to establish the theoretical foundations of the research as a basic study needed for developing the contents of verbal(language) behavior development for the infants with developmental disabilities. The methods used in the study was previous literature researches and interviews with subjects. The purposes of the study were divided into three parts. First, it was to analyze the educational needs of the infants with developmental disabilities in home settings. Second, it was to review and discover the language patterns of the infants with developmental disabilities. The third purpose was to devise the major guidelines of their language development's contents. The results of the study were described as the followings. 1.The relationships between the infants with developmental disabilities and their parents and their interactions should move to build the developmental attachments between them. 2.According to the literature findings of their language development patterns, Piaget concentrated on the functions of sensory motor environmental exploring in the language behavior development. The functions have been settled down into the important foundation for the infants' development. Thus, it was resonable that the content's development of the language behaviors for the infants with developmental disabilities should based on the function addressed by Piaget. 3.The language behaviors' patterns of the infants with developmental disabilities generally were classified into motor disabilities and sensory defect(deficiency). Therefore, the two factors should be considered for the constructions of the contents. 4.Constructing the contents of the language behavior developments for the infants with severely pervasive developmental disabilities such as autism, the improvements of two functions, imitative behavior and repetitive simple training should be considered.

T lymphocytes are thought to play a central role in cell mediated immune response. To Study the T lymphocyte proliferative response to 30-kDa antigen purified from Mycobacterium tuberculosis H37Rv, peripheral blood lymphocytes isolated from healthy subjects were stimulated with the 30kDa antigen, crude antigen or PHA. Healthy subjects were divided into three groups so that PPD(+), PPD(±) and PPD(-). The proliferations of lymphocytes were measured by the incroporation of ^3H-thyrnidine. The results were summarized as follows: 1. For the PPD(+) person, at concentration of < 1 ㎍/ml, the proliferative response to 30-kDa antigen resulted in a mild reduction but crude antigen showed relatively rapid reduction. For the PPD(-) person, decreasing the concentration of the both antigens showed rapid reduction of proliferation 2. The lymphocytes proliferations to 30-kDa antigen and crude antigen were significantly increased in PPD(+) group when compared to those in PPD(-) group, but PHA response was no significant difference. 3. The sensitivity and specificity of lymphocyte proliferation assay to 30-kDa antigen and crude antigen when compared with skin test results were 92.3%, 100% and 76.9%, 50%, respectively.

Abstract – The objective of this study was to prepare ketoprofen-loaded buccal adhesive patch. The adhesive patch was formulated by casting method using aqueous soluble polymer povidone K17 (PVP 17PF) as film-forming agent and hydroxypropylmethylcellulose (HPMC) as adhesive agent. To compare the effect of HPMC type, different molecular weight of K4M and K15M HPMC was used. The physicochemical properties of patches such as appearance, thickness, in vitro release, and adhesiveness were investigated. The concentration of ketoprofen was determined spectrophotometrically at a wavelength of 233 nm. The appearance of prepared patches was semi-transparent, light-yellow or almost colorless, and odorless. Thickness of each patches (n=6) was 0.895 ± 0.033 mm for K4M patch and 0.727 ± 0.036 mm for K15M patch. In vitro release test, both K4M and K15M patches showed over 20% release within 30 min. At 120 min, K4M and K15M patches demonstrated 95% and 67.5% release of ketoprofen, respectively, and up to 240 min, both patches released drug completely. Maximum adhesive force of K4M and K15M patches was 6.571 ± 2.703 gf and 2.735 ± 1.151 gf, respectively. Moreover, it took 28.29 ± 0.38 sec and 28.30 ± 0.34 sec for K4M and K15M patch to peel off them after adhesion, showing no significant difference. In conclusion, thickness, in vitro release, and maximum adhesive force could be modulated by alteration of polymer types.
