This study was undertaken to improve the perceived value of halophytes and contribute to the activity of the local economy by analyzing the antioxidant activity and mineral content of Suaeda japonica, Tetragonia tetragonoides, and Spergularia marina that grow wild on the mud flats and coastal areas. The total phenolic compound content found in each order is as follows: Suaeda japonica (3.674∼5.989 mg TAE/g dry wt.), Tetragonia tetragonoides (2.515∼4.471 mg TAE/g dry wt.), and Spergularia marina (2.450∼4.067 mg TAE/g dry wt.); DPPH radical scavenging and ABTS cation radical scavenging activities were also recorded in the same order. In the case of minerals, Iron(Fe) was relatively high in Suaeda japonica (960.1∼1,346.7 mg/kg), Manganese(Mn) in Tetragonia tetragonoides (197.1∼574.8 mg/kg), and Zinc(Zn) was relatively high in Spergularia marina (63.19∼216.56 mg/kg). It was confirmed that the mineral content of Suaeda japonica, Tetragonia tetragonoides, and Spergularia marina was significantly higher than that of Chinese cabbage, lettuce, leek, and spinach.

The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

The purpose of the study designed a simulational instructioil mode1 for problem solving learning applying the situational simulation and process simulation to the technique for developing situational learning coursewares based on constructivism. The follow conclusions were obtained from the results of the study. First, there's require simulation model based constructivism instructional theory. Second, we first studied and analyzed characteristics of infants. Third, we established a learning model with which infants might effectively learn numerical concept and developed a courseware in the basis of it. Fourth, in this model, the learner can explore his own path for himself. Fifth, the numeric concept simulation model consists of one simulators, such as polygon classfication, comparison, seriation, a helping room. Sixth, simulation model should be designed to be self- directed learning. Finally, the simulators are designed for a learner to get experiences just like in a real world. The helping room provides the basic concepts needed for simulation.

흡착에 의한 식염폐수의 처리

박영태,도갑수 慶北工業專門大學 1980 論文集 Vol.18 No.-

식품공장에서 배출되는식염폐수는 주로 채소를 소금물에 절이는 과정에서 생겨나며, 이 폐수는 생물학적으로 분해 불가능한 염과 유기고체의 혼합물로 되어 있으므로 응접 및 생물학적 처리만으로는 좋은 결과를 얻을 수 없다. 또한 소금의 농도가 10% 이상을 유지하므로 이 소금을 재생시키는 것이 바람직하다. 본 연구는 식염폐수를 공장에서 직접 채취하여 모래 층에서 여과한후 흡착질용액으로 하고 흡착제로 zeolite와 입상활성탄을 사용하여 회분흡착실험을 통하여 흡착평형과 흡착능 및 식염폐수의 재상용 능성을 조사하였다. 평형에서의 흡착량은 입상활성탄이 6.1㎎/g adsorbent, zeolite가 5.5㎎/g adsorbent가 되었다. 실제 공장에서 쓰여질 흡착탑의 설계를 위하여 fixed bed에서 연속실험을 했으며 유량과 폐수의 초기농도 및 흡착제 종류에 따른 break through curve 를 얻어 설계를 위한 제반인자를 설정하고 흡착 process를 제안하였다. 제안한 process의 고정투자비를 각 흡착제별로 계산하고 경제적인 타당성을 고찰한 결과 폐수의 량을 20㎥/day로 가정했을때 고정투자비 기준으로 약 0.12원/liter SPB 이 되어서 경제성이 있음을 알았다. A continuous process ofr recovery of spent pickle brine(SPB) by preliminary filteration on a sand bed to remove suspended solids, followed by adsorption treatment in an granular activated carbon and zeolite-sand micture column to remove colour and odor causing organic compounds is investigate. Batch isotherm adsorption experiments revealed that the adsorption capacity of the SPV-adsorbent system is respectively 6.1㎎ total organic carbon per gram granular activated carbon and 5.5㎎ total organic carbon per gram zeolite a t25℃. It is estimated that a low capital investment of 0.12 won per liter of recycled treated SPB is required for a 20㎥/day capacity. This cost is much lower than that of fresh salt, and thus will be defrayed by savings on recycled salt.

박영홍,백낙환,김현찬,김상효,홍관희,김기태,이기영 인제대학교 1994 仁濟醫學 Vol.15 No.2

인체 대장암 20례와 자궁경부암 10례의 암조직을 대상으로 c-Ki-ras 유전자 codon 12와 13에서의 점돌연변이를 알아보고자 polymerase chain reaction(PCR)과 single-strand conformation polymorphism(SSCP) 검사법을 시행하였다. 대장암의 경우 20례중 9례(45%)에서, 자궁경부암의 경우 10례중 1례(10%)에서 양성으로 나왔다. 대장암에서는 codon 12에서 GGT가 TGT로의 치환이 4례로서 가장 많았으며, AGT, CGT로의 치환이 각 1례였고 codon 13에서는 GGC가 GAC로의 치환이 2례, TGC로의 치환이 1례인 것으로 나타났다. 자궁경부암의 경우 codon 12에서 GGT가 AGT로의 치환이 1례인 것으로 나타났다. In an attempt to clarify the role of genetic alteration in the genesis of human colorectal and cervical cancers, tissue specimens from 20 patients with colorectal cancer and 10 patients with cervical cancer were examined for the presence of point mutation in K-ras2 exon 1 by single strand conformation polymorphism analysis of PCR product. Exon I of c-Ki-ras2 was amplified by polymerase chain reaction(PCR) and comparison was made between the normal and mutated genes by nondenaturing polyacrylamide gel electrophoresis(PAGE) of PCR product and nucleotide sequence analysis using asymmetric PCR with direct sequencing. Genomic DNA from white blood cells were used as normal control and those from A427 cell line were used as mutated control. 1.PCR product from A427 cell line showed a distinct migration shift pattern compared to the normal control in PAGE and the direct sequencing indicated that nucleotide sequence of codon 12 was mutated from GGT to GAT. In addition, there was a loss of normal allele in A427 cell line. 2.PCR product from 9 cases(45%) out of a 20 colon cancer patients showed migration shifts in PAGE, and all of these 9 patients invariably demonstrated mutation of ras gene, either in codon 12(6 cases:30%) or 13(3 cases:15%). The base substitutions in codon 12 were: from GGT to AGT(1), CGT(1), or TGT(4). Base changes in codon 13 were from GGC to TGC(1) or GAC(2). 3.PCR product from 1 cases(10%) out of a 10 cervical cancer patients showed migration shrifts in PAGE, Invariably demonstrated mutation of ras gene in codon 12. The base substitutions was from GGT to AGT(1) TQE incidence of point mutation of c-Ki-ras in colon cancer was high, however, it was low in cervical cancer, which showed the relation of ruts gene mutation with colon cancer. PCR -SSCP analysis is a simple, rapid and efficient method of detection of point mutation, especially when dealing with multiple samples.

A series of experiments were conducted to investigate the distribution ratio of the biotypes of brown planthopper(BPH), Nilaparvata lugens Stal, migrated into the rice field of Korean peninsula from southern Chinese continent during the rice crop growing season, the feeding amount, and the emergence rate of BPH biotypes fed on 60 to 70-day-old rice cultivars with different resistance genes. The percent biotype distribution of the female BPH collected in southern coastal regions of Korean peninsula showed that in 1986, 1987, and 1988 the BPH biotype-1 was predominant species accounting for 61.2%, 59.7%, and 52.4%, respectively. Whereas biotype-2 was 21.9%, 29.7%, and 26.2%, and biotype-3 was 17.0%, 12.6%, and 21.4%, respectively. Since Indonesian rice cultavars, IR 36, Cisadane, and Krueng Aceh, to the BPH female adults collected in southern coastal regions of Korean peninsula were shown partially susceptible reaction, the primary source seems to be migrated from the tropics to Korea by way of southern China and the subtropics. The feeding amount of biotype-2 on Cheongcheongbyeo with resistant Bph 1 gene and biotype-3 on Milyang 63 with resistant bph 2 gene was as high as Milyang 23 with no resistant gene. But Gayabyeo with resistant Bph 1 and bph 2 gene was highly resistnat to biotype-1,2,and3. The emergence ratio of the three BPH biotypes on Milyang 23 was higher than on the other rice cultivars, and that of biotype-2 on Cheongcheongbyeeo and biotype-3 on Milyang 63 was as high as on Milyang 23.

朴英泰 東亞大學校 學生生活硏究所 1993 學生硏究 Vol.21 No.-

The purpose of this study is to analyze the interactive instruction and learner's motivation, and to develop CAI program for improving the attractiveness of instruction based on the interactive instruction and learner's motivation. To improve the interactive instruction, it is necessary to activate the learner's control and learner's regulation. For activating the learner's control, program needs to be composed of a variety of branches, and learners should have opportunities of a wide range of choices. For activating the learner's regulation, program needs to be guided by metacognition. To improve the learner's motivation, it is needed to consider the elements of motivation: attention, relevance, confidence, and satisfaction which are proposed by Keller. The characteristics of CAI program for improving the attractiveness of instruction based on the interactive instruction and learner's motivation are as follows: 1. This program proceeds through seven steps: identifying the content, prediction, planning, executing, formative evaluation, general evaluation, and self reinforcement. 2. The movement among steps is free, and is carried away at learner's will. 3. At the step of identifying the content, the learner decides the contents and amounts of learning. 4. At the step of prediction, the learner predicts the degree of achievement and the time required for learning the tasks. 5. At the step of planning, the learner selet the method of presentation of contents and the method of learning the tasks. 6. At the step of executing, the learner learns the tasks in accordance with program. 7. At the step of formative evaluation, the learner is examined about the contents which is learned a moment ago. 8. At the step of general evaluation, the learner is examined about the contents which has been learned before. 9. At the step of self reinforcement, a variety of feedback and knowledge of results are presented.

Abstract The purpose of this thesis is to investigate the age differences in motivation related to Maslow's need hierachy. For this, 437 students, age 8 years to 30 years(216 Females, 221 male) were sampled. They were divided four age groups(8-12, 13-17, 18-22, 23-30). Using the Scale, they ranked statements representing Maslow's five needs on 11 life components. Analysis of Variance(Age×sex) yielded significant age differencs for four needs (self-actualization, esteem, safety, Physiological needs).The findings of this thesis are summerized as below; ① Self actualization needs are the highest than any other needs at every age class, and the older, the higher. ② Esteem needs peak at age 18∼22, but safety needs are are reversed. ③ Love needs are alike at every age class and higher than any other needs except self actualization needs ④ Physiological needs are the lowest at every age class .
