The aims of this research study is to clear the differences of the learning effects and the cognition of Home Economics by sex in the middle school and to collect the future-oriented educational datas, after implementing the 6th education curriculum. The results of the study are as follows ; 1. Most of students had the cognition that Home Economics is a subject matter of a needful knowledge and skill for the family life, half students a cultural subject matter for the modern life. The former was supported by female students, the latter by male students. 2. Most of students were interested in actual training fields of cooking and hand-sewing, had a strong interest about a field of physical and social-psychological growth. The differences by sex were statistically significant in these fields. 3. Most of students had positive responses in the learning effects of Home Economics. The most useful field was cooking and the worst was the structure and method of sewing machine. 4. The shortage and the dissatisfaction in the learning of Home Economics were lacking of the actual training hours, the old-fashioned teaching methods and the shortage of teaching materials etc.

Purpose: Dynamic Myofascial Release(DMFR) was conducted as it was expected to be effective improving body movements and Chronic Low Back Pain when the MFR and joint mobility were mobilized in a direct or indirect manner to approach the problematic area. Methods: 30 patients with non-specific low back pain were selected and randomly divided into DMFR group (N = 15) and control group (N = 15). The control group was received treatment with limited of trunk's ROM and DMFR group was received DMFR. Dynamic Myofascial Release is a separate therapeutic area from joint mobilization. Because Dynamic Myofascial Release is a therapeutic method for myofascial that is the connective tissue that connects the whole human body. And because the patient and the therapist are involved in the treatment at the same time, and the patient's active posture or participation includes low intensity movements that can be released only by breathing. The other is that the therapeutic action that causes movement around the fixed axis is extremely restrained as if it reminds of slow video and static energy therapy Results: The results showed that the mobility and standing balance of the trunk increased significantly compared to the control group (Lee Dong-woo et al, 2019). Dynamic Myofascial Release is expected to help improve trunk movement and non-specific low back pain, and should be used properly with Myofascial Release (P<.05) Conclusions: Dynamic Myofascial Release(DMFR) was effective. These of direct or indirect methods to access problematic areas, including MFR and joint mobility, was effective in improving body movements and lumbar pain.

The Binary Scheduling Wheel(BSW) algorithm was proposed to carry on manage buffer efficiently at implementing of WRR scheduler. But, BSW algorithm cause serous performance degradation of cell delay and maximum queue length because it allocates more weight than the weight allocated actually in VC and could not serve cell if the VC queue is empty. In this paper, we propose new BSW of the old BSW structure. Also, we develop a cell scheduling algorithm which is suitable for the new BSW structure. The proposed BSW structure and the developed algorithm are capable of maintaining the allocated weight of each VC correctly, and decrease average cell delay and average buffer length by serving other VC cell when the selected VC queue is empty, and increase cell service ratio as a whole. The evaluation results show that the proposed structure can implement WRR algorithm more efficiently than the old BSW.

Fumonisin에 대한 효소면역측정법(ELISA)을 개발하기 위하여 특이항체를 생산하고, 분석조건을 확립하여, 인위적으로 오염시킨 옥수수 시료의 분석을 행하였다. Fumonisin B_1 (FB_1)을 cholera toxin (CT)에 결합시킨 FB_1-CT conjugate를 면역원으로 하여 Freund's adjuvant와 함께, 또는 단독으로 두 군의 토끼에 면역하고 특이항체를 생산하였다. 항혈청을 ELISA로 분석한 결과 그 adjuvant와 함께 면역한 경우 항체역가(titer)가 높게 나타났다. 가장 높은 항체역가(1 : 16,000)를 나타낸 항혈청 및 그로부터 정제한 항체를 이용하여 간접법 및 직접법에 의한 경합적 ELISA(ciELISA 및 cdELISA)를 각각 확립하였다. 이 항체의 유사독소와의 교차반응을 ciELISA로 조사하였을 때, FB_3에 대한 교차반응율은 2%로 매우 낮았으나, FB_2에 대한 것은 179%로 다소 높았다. FB_1의 검출한계는 ciELISA에서 0.03ppb, cdELISA에서 0.3 ppb로 각각 나타났다. 실제 곡물시료의 분석에 ELISA 활용가능성을 조사하기 위하여 인위적으로 FB_1을 오염시킨 옥수수를 75% methanol로 추출하고 그 회수율을 측정한 결과, 분석이 불안정하여 회수율이 일정하게 나타나지 않았다. 그러나 방해물질의 제거를 위하여 시료추출액을 strong anion exchange(SAX) cartridge를 거쳐 세척한 다음 분석하였을 때, 3~10 ppm 범위의 FB_1 오염 옥수수에서 평균 34%(CV의 평균, 8.2%)의 안정된 회수율을 보였다. In order to develop enzyme-linked immunosorbent assay (ELISA) for fumonisins, production of specific antibodies, establishement of ELISA conditions, and quantitation of the toxin from spiked corns by ELISA were performed. Fumonisin B_1 (FB_1) conjugated to cholera toxin (CT) with or without Freund's adjuvant was subcutaneously injected into 2 groups of rabbits. When the titer of the antisera produced by each rabbit tested, higher titer was observed in case of the immunization with the adjuvant. By use of the antiserum showing the highest titer (1 : 16,000) and its purified antibodies, competitive indirect and direct ELISA's (ciELISA and cdELISA) were established, respectively. When the cross-reactivity of the antibody against fumonisin analogs was investigate by the ciELISA is was very low against B_3 (2%) but high against fumonisin B_2 (179%). The sensitivity of the ELISAs was also very high, because the detection limit for FB_1 was 0.03 ppb in ciELISA and 0.3 ppb in cdELISA. When the ELISA's were applied to the spiked corns after extraction with 75% methanol, the assay recovery of FB_1 was too unstable to assay. However, when cleanup by strong anion exchange (SAX) cartridge was introduced to remove interfering materials, the mean ELISA recovery of FB_1 from corns spiked to 3~10 ppm was found to be 34.0% and stable (mean of CV, 8.2%).

고위인지기능 중 시자극에 대한 지각적 관계를 파악하고 유추에 의해서 추론하는 능력을 측정한다고 알려진 SPM(Standard Progressive Matrics)검사를 통해, 추론 기능의 취약성이 예측되는 정신과 환자 집단(기질적 뇌손상, 우울증, 정신분열병)과 정상통제집단에, 추론 기능을 중심으로 고위 인지 기능 손상의 특징적 양상을 비교해 보고자 한다. 방법: 정신분열병 환자 29명, 우울증 환자 22명, 뇌손상 환자 32명을 대상으로 SPM을 실시하여, 집단간의 수행 양상의 차이를 비교하되, SPM 총점과 5개의 소검사 점수를, 변량분석 및 사후 검증을 통해 비교하였다. 정상 집단과 뇌손상 집단간 SPM 소검사의 판별분석을 시행하였다. 결과: 정신과 환자 집단의 SPM 수행 결과에 있어 뇌손상환자, 우울증환자, 정신분열병환자 세 집단 모두 정상집단에 비해 유의미하게 낮았으며, 특히 뇌손상환자는 우울증환자, 정신분열병환자보다도 유의미하게 낮은 수행을 나타냈다. B,E 소검사가 뇌손상 집단과 정상 집단을 가장 잘 변별해주는 소검사로 판별되었다. 정신분열병환자와 우울증환자간에 유의미한 차이는 관찰되지 않았으며, 모양의 배열과 조합을 추론해야하는 D 소검사에서는 우울증환자와 뇌손상환자간에 유의미한 차이를 나타냈으나, 정신분열병환자와 뇌손상환자간에 유의미한 차이를 보이지 않았다. 결론: 추상화 추론 기능을 중심으로한 고위인지기능 저하가 예상되는 우울증, 정신분열병, 및 뇌손상환자간에 인지적 손상의 특징적 양상을 SPM 검사가 잘 변별해 줌을 보여주었다. 뇌손상 환자의 인지적 손상은 정신분열병 및 우울증 환자의 인지적 손상과는 질적으로 차이가 있음을 시사하는 것이며, SPM이 지능 검사의 대체 검사뿐만 아니라 신경 심리 검사로서 활용될 수 있음을 확인한 것이다. Objectives: This study was aimed to compare abstract reasoning in patients with mental disorders ; Depression, Schizophrenia, Organic Brain Syndrome(OBS), and normal control group using Standard Progressive Matrices(SPM), known as a test measuring visual pattern matching ability and reasoning ability by analogy. Method: SPM test in Vienna Test System□ was administered to 82 normal adults, 29 schizophrenic patients, 22 depression patients, and 32 OBS patients. SPM total score and 5subtest scores in four groups were compared, using ANOVA and post-hoc comparison. SPM subtest scores in OBS and normal group were compared, using discriminant function analysis. Results: SPM total score and all subtest scores in mental disorders group(schizophrenia,depression, OBS) were lower than in normal control group. SPM total score and all subtest scores in OBS group were lower than in schizophrenia and depression group. No difference between SPM total score in Schizophrenia and depression group was found. Discriminant function of B, E subtest was the hightest. Conclusions: The impairment of higher cognitive function, especially abstract reasoning impairment in OBS, was qualitatively defferent from that of schiophrenia and depression. SPM can differentiate specific pattern of abstract reasoning impairment in mental disorders, so SPM can be used not only as a substitute for intelligence test but also as a neuropsychological test.

김동한,신용서,전승호,백승화,이갑상 圓光大學校 1992 論文集 Vol.26 No.2

두부의 저장성 향상을 위해 보존료를 첨가하여 저장중 두부의 미생물상과 이화학적 변화를 검토하였다. 보존료 첨가에 의한 두부의 기호도 변화는 큰 차이가 없었으며 부패가 진행될 수록 적정산도와 amino태 및 ammonia태 질소량은 증가하였다. 두부는 acetic acid로 응고시키는 것이 CaCl₂보다 보존료에 의한 저장성 향상에 효과적이어서, acetic acid에 0.05% K-sorbate와 3% NaCl을 혼합첨가한 구는 저장중 이화학적 변화 및 호기성, 혐기성 세균수가 ?? cell/g수준인 점을 고려해 볼 때 30℃에서 48시간까지 저장이 가능하였다. In order to improve the shelf life of Tofu, the effects of preservatives on Tofu were investigated for microbiol and physicochemical changes during its storage. The sensory evaluation was not deteriorated by preservatives (0.05% K-sorbates). According to the progression of spoliage of Tofu, titratable acidity, and amino and ammonia nitrogen contents were increased. The effect of chemical preservatives on the shelf life of Tofu was shown to be stronger in the Tofu by acetic acid than in that by CaCl₂. The presence of 0. 05% K-sorbate and 3% NaCl as a preservative in Tofu by acetic acid extended it's shelf life upto 48 hrs at 30℃.

환기정도에 따른 수술실용 신발 종류가 수술실 오염에 미치는 영향 : How to Choose Suitable Shoes?

Background : Various types of protective footwear have been used to minimize bacterial contamination in operating rooms. In recent years, debate has arisen concerning the need for use of such protective footwear. This study was designed to provide useful data about choosing shoes most suitable for the surgical environment. Methods : Between November, 1999 and January, 2000, we performed this experimental study by comparing effect of three types of shoes (i.e., disposable shoescover, operating room-restricted shoes, and ordinary shoes) on bacterial contamination of operating rooms equipped with two different ventilation systems (i.e., high air-change, low air-change) respectively. Data were collected during two-hour sham operations in which subjects and their activities were strictly standardized. Bacterial flora were sampled from the study area floor and air colony-counts were measured. Results : In experiments involving high air-change ventilation system, there was a significant difference of floor contamination between three types of shoes, but no difference of air contamination. Under low air-change system, there was a significant difference of both floor and air contamination between three types of shoes. Conclusion : The results show that protective footwear would be unnecessary in the operating room with high air-change ventilation system, but it is important to choose suitable shoes carefully under low air-change system. Therefore, the use of outdoor shoes can be considered under high air-change system, but it would seem sensible to apply their first use in less bloody operations at the day surgery center or out-patient department to prevent transfer of body fluid into the outside environment.
