The titled study has been conducted by collecting questionnaires from 146 secondary school science teachers. The results analysed are as follows. 1. More than half of the science teachers think that they have too much loads on teaching and other works. They hope to teach 15 hours a week or less and also to be waived from extra works not related with teaching. 2. Most of the science teachers think that they are not paid enough salary. And more than half of them feel their economic and social status are below average. 3. Science teachers think that they have good relations with their colleagues but many of them are not much satisfied with the attitudes of students and their parents. 4. Science teachers want better facilities for teaching and for their office. 5. Science teachers feel difficult in teaching laboratory class. They pointed out that it is time-consuming to prepare for experiments and clean up the laboratory and that evaluation of experimental work is not easy. 6. Science teachers appeal that they have difficulties in teaching inquiry skills due to the crowded class and also lack of teaching materials for this purpose.

The future society will demand that enables one to solve in many fields by connecting various informations in many fields and then creating his own information. In the coming society, creativeness will be regarded much important. This ability can be developed with materials through group activities experimental class in math classes. This classes using these materials are not teacher-oriented, explanatory classes but student-oriented ones. They offer students opportunities to think by themselves and expand their potential abilities. They are suitable for rising and keeping student's interests. Therefore experimental classes through group activities enable students to think mathematically and make them recognize the importance of mathematical approach by letting them work connecting other subjects or things in real life. They can develop not only expressive, communicative ability and cooperative spirit, but also the ability to transcend the class itself and then reorganize facts in new insights. Besides, math classes with experiments can arouse student's curiosity familiarizing them with mathematics. Moreover, they can expand student's originative and problem-solving abilities.

A najor current challenge and constraint in cervical cancer research is the development of vaccines against human papilloma virus (HPV) epitopes. Although many studies are done on epitope identification on HPVs, no computational work has been carried out for high risk forms which are considered to cause cervical cancer. Of all the high risk HPVs, HPV 16, HPV 18 and HPV 45 are responsible for 94% of cervical cancers in women worldwide. In this work, we computationally predicted the promiscuous epitopes among the E6 proteins of high risk HPVs. We identified the conserved residues, HLA class I, HLA class II and B-cell epitopes along with their corresponding secondary structure conformations. We used extremely precise bioinformatics tools like ClustalW2, MAPPP, NetMHC, Epi,Jen, EpiTop 1.0, ABCpred, BCpred and PSIPred for achieving this task. Our study identified specific regions 'FAFR(K)DL' followed by 'KLPD(Q)LCTEL' fragments which proved to be promiscuous epitopes present in both human leukocyte antigen (HLA) class I, class II molecules and B cells as well. These fragments also follow every suitable character to be considered as promiscuous epitopes with supporting evidences of previously reported experimental results. Thus, we conclude that these regions should be considered as the important for design of specific therapeutic vaccines for cervical cancer.

The ethical issue is one of the most important themes in both science and environmental education. Especially related to the right of other species, animal dissection has been brought about two contradictory attitudes. In spring 1996, a survey was conducted to assess the status of animal dissection in secondary schools and the awareness of 94 biology teachers and 422 secondary students toward animal dissection. And the meaning of animal dissection in biology class was discussed in terms of environmental education. The findings were as follows: First, most of students(96.6%) had participated once or twice to animal dissection experiments(eg. fish, frog, shellfish, cuttlefish and chicken). And about half of teachers (57.4$\sim$64.9%) and some students(41.9%) felt ethical conflict in animal dissection. Second, many teachers(81.0%) and students(87.1%) thought that animal dissection was effective method to achieve the goal of biology education, but they needed more consideration on the respect for life in animal dissection experiment. Third, many teachers(88.3%) had students, who objected to animal dissection, participate obligatorily or passively. Fourth, teachers and students thought that audio-visual media such as video(teachers 63.5%, students 39.7%), computer simulations(teachers 31.7%, students 28.1%) and models(teachers 22.2%, students 24.1%) could be effective as alternatives. These findings suggest that animal dissection experiment, although it is needed to achieve the goal of biology education, requires careful consideration on the rights of animal and the respect for life, and alternatives for students who object to animal dissection in biology class.

The purpose of this paper is to investigate how the English classes in secondary schools in Korea are in terms of communicative nature. After literature study, COLT parts A and B were used to analyze three kinds of English classes: a common class type taught by a school teacher who had won 1st prize at TEE contest, a team teaching class taught by NNS and NS, and a model class taught by a pre-service English teacher. Their communicative English classes were videotaped and transcribed for analysis by COLT. The results of the study revealed that students participated in the classes mostly as a unit and, therefore, did not get many meaningful chances to speak English. Second, creative language-use opportunities were barely found during classes. Third, the group work seemed to be prepared before the class, not to be done during the class. Therefore it is likely to be learned from memorization rather than meaningful communication. These results suggest English classes in schools be more communicatively oriented for successful English learning. Further study should be conducted in order to make English classes more communicative to help students communicate their genuine messages in English and to help teachers teach English efficiently.

G protein-coupled receptor(GPCR) family is a cell membrane protein, and plays an important role in a signaling mechanism which transmits external signals through cell membranes into cells. Now, it is estimated that there may be about 800-1000 GPCRs in a human genome. But, GPCRs each are known to have various complex control mechanisms and very unique signaling mechanisms. GPCRs are involved in maintaining homeostasis of various human systems including an endocrine system or a neural system and thus, disorders in activity control of GPCRs are thought to be the major source of cardiovascular disorders, metabolic disorders, degenerative disorders, carcinogenesis and the like. As more than 60% of currently marketed therapeutic agents target GPCRs, the GPCR field has been actively explored in the pharmaceutical industry. Structural features, and class and subfamily of GPCRs are well known by function, and accordingly, the most fundamental work in studies identifying the previous GPCRs is to classify the GPCRs with given protein sequences. Studies for classifying previously identified GPCRs more easily with mathematical models have been mainly going on. Considering that secondary sequences of proteins, namely, secondary binding structures of amino acids constituting proteins are closely related to functions, the present paper does not place the focus on primary sequences of proteins as previously practiced, but instead, proposes a method to transform primary sequences into secondary structures and compare the secondary structures, and then detect an unknown GPCR assumed to have a same function in databases of previously identified GPCRs.

The purpose of this study is to identify the types of professional teaching practice of Home Economics teachers who are working at Korean secondary school for changing their professional teaching practice and developing home economics curriculum. A mail questionnaire, Professional Teaching Practice(PTP) was used to survey randomly selected 525 Home Economics teachers. The professional teaching practices examined were customary-instrumental, interactive and reflective practices. Customary-instrumental practice was the predominant type of professional teaching practice used by Home Economics teachers. About 26% of the teachers used reflective practice, and 14.67% used interactive practice. Only the number of students was significantly related to their professional teaching practices. Five influential factors on teaching practices identified by Home Economics teachers emerged in the following order: examination-centered educational system, lack of class hours, lack of resource materials and facilities, demands from the Ministry of Education, school administrators, or parents, and large class sizes.
