문충식,김범기 한국교원대학교 과학교육연구소 1998 청람과학교육연구논총 Vol.8 No.1

선그래프는 과학에서 정보를 전달하는 수단으로써 뿐만 아니라 실험의 결과를 해석하는 수단으로 유용하게 활용된다. 그러나 학생들은 그래프의 시각적이면서도 추상적인 특징 때문에 해석이나 이해에 상당한 어려움이 있다. 따라서 선그래프 이해의 지각ㆍ인지 과정을 분석하는 것이 매우 중요하다. 본 연구의 목적은 선그래프 해석과 이해에 관한 지각ㆍ인지 과정에서의 한 모형을 제시하는 것이다. 이 모형은 Pinker의 그래프 도식 이론과 Fisher의 정보 처리 이론에 기초를 두고 있으며, Lohse, Shah, Winn 등의 연구를 참고하여 제시하였다. 그리고 이 모형의 특징은 선그래프 문제를 해결하는 과정을 내용 독립적인 선그래프 해석과정과 내용 의존적인 선그래프 이해과정으로 나누었다. Line graphs are particularly effective in communicating relationships. They can convey vast amounts of information that cannot be communicated effectively by words or numbers alone. Thus, line graphs allow us to communicate scientific information and to see scientific data analyses. However, students are weak in their ability to comprehend line graphs because the features of line graphs are visual and abstract. McDermott et al. (1983) have shown that this is a problem even for many university students in the sciences. Then, it is very important to analyze the perceptual and cognitive processes in the comprehension of line graphs. The purpose of this study is to propose a model of line graph comprehension that includes perceptual and cognitive processes. This model is based on the graph schema theory of Pinker (1990) and the information processing theory of Fisher (1992). The major processes are the interpretation process and the comprehension process. In the interpretation process of line graphs, defined that the visual information of graphs is assimilated with the graph schema and is simultaneously accommodated to graph schema. The comprehension process of line graphs is one in which the result of the graph interpretation is assimilated with the existing conceptual schema on graphs and is simultaneously accommodated to the existing conceptual schema on graphs.

This study was conducted to examine middleㆍhigh school 720 students in seven regions of middleㆍsmall city and town, Myon for 2 months from March 2 through April 30, 2002 in order to realize a side of school health education in middleㆍhigh school and health education need as well as health education specialist in school in the future. The results of this study can be summarized as follows. 1. Health condition is now 'normal' is 51.0%, 'good' is 45.0%, 'not good' is 4.1% and health condition of children is good as much as education level of mother is higher. 2. Experience to learn health education in school for one year recently is 'no' is 39.6%, 'don't know' is 32.6%, 'yes' is 27.8% and it represents health education in school doesn't work well and experience to learn health education is lower and lower in town and Myon. 3. Health education ways to work in school now are 'Movie, Video, Slide' is 40.7%, 'education as groups of nurse-teacher' is 38.6%, 'to distribute health education material and book' is 7.7%, 'education by setting an example' is 3.4%, 'the others' is 9.7%. 4. Time of appropriate health education for one time is 'about a hour' is 56.7%, 'about 30 minute' is 33.8%, 'about two hour' is 7.6%, it represents this situation is because of what students' time is lack and burden about a curriculum in an education administratin and school classed of a focused school score. 5. The average score of satisfaction of health education in school is 16.99±0.58, 'men' is 1.79±0.60, 'women' is 1.61±0.55 as the distinction of sex, satisfaction level of men is higher than women. 6. Learning route about health information is 'through mass media' is 59.9%. 'through family, friend' is 15.0% 'health education lecture' is 7.2%, 'printing media' is 6.1%, 'medical institution' is 5.6%, 'the others' is 5.1%, 'public health center' is 1.0%, 'through mass media' is the highest percent as each 59.1% and 60.6% in all of men and women. 7. The most efficient education way of health education is 'movie, video, slide' is 32.6%, 'health education specialist who works school' is 21.9%, 'school health education by nurse-teacher' is 16.0%, 'way through mass communication' is 11.6%. 8. The appropriate health education specialist in the future is 'health education specialist who has qualifications' is the highest as 64.5%, 'nurse-teacher' is 12.4%, 'medical personnel(doctor, a physician of oriental medicine etc.,)' is 11.0%, 'staff in public health center' is 7.2%, people in other regions(health and medical professor etc.,) is 7.0%, it represents school health education is not actual and is formal now in second hand. 9. The most necessary health education program is 'program of stress solution' is the highest as 24.9%, 'program of no smoking' is 22.7%, 'sexual education program' is 19.8%, 'school violence program' is 8.8%, 'isolate from their friends prevention program' is 8.0%, solution program of stress which gives student by school score was very necessary. Therefore, school health education is formal and inefficient because school education focuses on an entrance exam, so middleㆍhigh school students decrease concern and interest about health education. Furthermore, reliance is gotten down about nurse-teacher who takes charge of school health, a charged person of school health education wants more chargeable health education staff. And a solution program of stress that gives students by school score was very necessary. According to active concern and planned, systematic school health education is necessary to give right health knowledge, health maintenanceㆍpromotion and setting of appropriate health education specialist is very urgent.

This study was conducted to examine aspects of health and safety education and demand level of safety education in construction job sites in order to provide direction of safety education development. The subjects of this study were 566 workers who were working in construction job sites located in Daegu City and Kyungbuk Province. Data were collected from June 1, 2002 to August 30, 2002. The results of this study can be summarized as follows. 1. According to safety education by experience methods, the proportion of education by lecture was highest (90.6%). The proportion of education by field practice was 13.1%. 2. Among the education methods which they thought as the most desirable method, the proportion of audio-visual education was 39.4% and the proportion of education by experience was 37.5%. Those who had more monthly income and higher education level preferred audio-visual education, while those who were younger and less educated preferred education by experience. 3. In the case of the contents of the safety education which they thought as the most important one, the proportion of enhancement of safety awareness and education of risk factors was highest (24.7%). The groups of older workers, having longer working period, and belonging to higher education level preferred these contents. 4. According to the factors which were most important to increase effectiveness of the safety education were workers' voluntary participation (27.7%), 40 to 49 years old (27.7%), and monthly income of one million, five hundred thousand won to one million, nine hundred ninety thousand won (32.0%). The proportions of lower educated workers and working as daily workers were also high. 5. The variable which most influenced the safety education was age. The safety awareness of construction job sites was the second highest influential variable. From above results, it is clear that the workers' participation in the safety education was low since most of the safety educations were formal education by lecture. Although they participated in the education, the education was also not effective because they compulsorily participated in it. Therefore, it can be concluded that effective alternative policies must be formulated.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Transcriptome Profiling and Characterization of Drought-Tolerant Potato Plant (Solanum tuberosum L.)

Moon, Ki-Beom,Ahn, Dong-Joo,Park, Ji-Sun,Jung, Won Yong,Cho, Hye Sun,Kim, Hye-Ran,Jeon, Jae-Heung,Park, Youn-il,Kim, Hyun-Soon Korean Society for Molecular and Cellular Biology 2018 Molecules and cells Vol.41 No.11

Potato (Solanum tuberosum L.) is the third most important food crop, and breeding drought-tolerant varieties is vital research goal. However, detailed molecular mechanisms in response to drought stress in potatoes are not well known. In this study, we developed EMS-mutagenized potatoes that showed significant tolerance to drought stress compared to the wild-type (WT) 'Desiree' cultivar. In addition, changes to transcripts as a result of drought stress in WT and drought-tolerant (DR) plants were investigated by de novo assembly using the Illumina platform. One-week-old WT and DR plants were treated with -1.8 Mpa polyethylene glycol-8000, and total RNA was prepared from plants harvested at 0, 6, 12, 24, and 48 h for subsequent RNA sequencing. In total, 61,100 transcripts and 5,118 differentially expressed genes (DEGs) displaying up- or down-regulation were identified in pairwise comparisons of WT and DR plants following drought conditions. Transcriptome profiling showed the number of DEGs with up-regulation and down-regulation at 909, 977, 1181, 1225 and 826 between WT and DR plants at 0, 6, 12, 24, and 48 h, respectively. Results of KEGG enrichment showed that the drought tolerance mechanism of the DR plant can mainly be explained by two aspects, the 'photosynthetic-antenna protein' and 'protein processing of the endoplasmic reticulum'. We also divided eight expression patterns in four pairwise comparisons of DR plants (DR0 vs DR6, DR12, DR24, DR48) under PEG treatment. Our comprehensive transcriptome data will further enhance our understanding of the mechanisms regulating drought tolerance in tetraploid potato cultivars.

Pseudolite/Ultra-low-cost IMU Integrated Robust Indoor Navigation System Through Real-time Cycle Slip Detection and Compensation

Kim, Moon Ki,Kim, O-Jong,Kim, Youn Sil,Jeon, Sang Hoon,No, Hee Kwon,Shin, Beom Ju,Kim, Jung Beom,Kee, Changdon The Institute of Positioning 2017 Journal of Positioning, Navigation, and Timing Vol.6 No.4

In recent years, research has been actively conducted on the navigation in an indoor environment where Global Navigation Satellite System signals are unavailable. Among them, a study performed indoor navigation by integrating pseudolite carrier and Inertial Measurement Unit (IMU) sensor. However, in this case, there was no solution for the cycle slip occurring in the carrier. In another study, cycle slip detection and compensation were performed by integrating Global Positioning System (GPS) and IMU in an outdoor environment. However, in an indoor environment, cycle slip occurs more easily and frequently, and thus the occurrence of half cycle slip also increases. Accordingly, cycle slip detection based on 1 cycle unit has limitations. Therefore, in the present study, the aforementioned problems were resolved by performing indoor navigation through the integration of pseudolite and ultra-low-cost IMU embedded in a smartphone and by performing half cycle slip detection and compensation based on this. In addition, it was verified through the actual implementation of real-time navigation.
