The purpose of this study was to investigate into common science and Science-Technology-Society education movement which are concerned in newly reformed 6th curriculum. These data were obtained by the survey of 291 high school science teachers who have no experience for the workshop of the common science in Kwangju city and 120 high school science teachers who have experience for the workshop of the common science in Kwangju city and Chollanamdo. The results were as follows: 1) They responded that the physics is more closely subject for the common science and thereby it could be charged for the common science by teacher of physics. 2) The 96.90 percent of the respondents (B-group) have confidence with teaching common science subject. 3) They favored that a device for the application of STS Thoughts is added last part of each chapter, last chapter or adequately introduce to each teaching. 4) They are not concerned about overlap with the contents of common science and each science contents (A-group:74.58 percent, B-group:78.35 percent). 5) They wondered about the various items of teaching and the lack of scientific surrounding Knowledge for solving problems. 6) They responded that if the common science are implicated into the current high school, the sciences will become a interesting. 7) Before the common science have become established, they was demanded a improvement of currently University Entrance Examination systems.

The objectives of this study were to analyze ecological effects on effluents from the Sagok Stream (Chonnam province) as an abandoned mine drainage through necropsy-based health assessments and fish exposure tests, and to conduct In situ field pilot tests for restoration of stream water. Also, we analyzed water quality including general parameters and heavy metals. The tests were performed three times on April 2005, April 2006, and April 2007. Also, we constructed a reactor facility in the outflowing point of the abandoned mine for the remediation of AMD wastewater. In lab test, death rates in all three treatments were ${\geq}50%$ in the experiments. Necropsybased fish tissue assessments using the Health Assessment Index (HAI), indicated that the most frequently damaged tissue was liver (average: 20.8). Values of Health Assessment Index were lower in the control than any other treatments of T1, T2, and T3 and three treatments showed a distinct toxicity impacts by the AMD. In situ lethal test, concentration of Fe, Al and Zn decreased particularly by 85%, 99% and 94%, respectively through the disposal facility. Values of pH, ranged from 3.1 to 7.0, increased by 2.3 fold (mean=5.1) along with the reduction of metal contents. All fishes in P1 cage died 100% on 3 days later after the experimental setting, while all fishes in the P6 died 100% on 9 days later. Overall, these results evidently provide a key methodology for pilot test using the disposal facility and also clarify the toxicity of AMD once again, so this approach used in the pilot facilities here may reduce the acidic and toxic effects in the abandoned mining drainage.

The purpose of this study was to identify the perception between real and ideal body shapes of college students and to investigate the preferred body shape of college students. The research subjects numbered one hundred forty five male and female students, aged 20 to 29, who lived in Gwangju and Chonnam province. The anthropometric data was collected including both direct and indirect measurements. The data was analyzed by mean and standard deviation, t-test, and factor analysis. The results of t-test showed the significant difference($p{\leq}.001$) between real body size and ideal body size. The result showed that male students want to have bigger chest circumference and a taller height than their real body, the research also showed that the female students want to have a narrow bust and hip width along with a taller height than real body. Regarding ideal body shape, male students pursued bigger height and want an inverted-triangle body shape. On the other hand, female students pursued bigger height and slim body shape. This study established the factors(dimension of torso, height, the side shape of torso, and shoulder shape) as the perception between real and ideal body shapes. In terms of real body, the factor analysis shows two contrasting results in which the height is the most important factor for female students, while the torso dimension is the most important factor for male students. In terms of ideal body, the height factor is the most important for both the male and female students.

We observed the osteological development of larval and juvenile red spotted grouper (Epinephelus akaara) in order to generate data for the assessment of skeletal deformities and to inform phylogenetic systematics research. Larvae and juveniles were obtained from a aquafarm in Muan-gun, Jeolla-namdo Province, Korea. The average water temperature at the time of breeding was $23.0^{\circ}C$ and average water salinity was 33.0 psu. Freshly hatched fish larvae had not undergone any ossification, but ossification of the parasphenoid bone, which forms the base of the cranium, occurred as the juveniles reached an average body length (BL) of 2.49 mm. At the same time, ossification of the preopercle and opercle occurred in the operculum, and ossification of the maxilla, which forms the upper jaw, and the dentary bones, which form the lower jaw, began. In addition, ossification of the vertebra occurred by formation of 7 vertebral centra and the neural spine in the abdominal vertebra. When the juveniles reached an average (BL) of 5.22 mm, ossification of the nasal, lateral ethmoid, and alisphenoid bones occurred in the cranium; ossification of the endopterygoid and metapterygoid bones began in the palatine region; and ossification of the hypohyal and interhyal bones occurred in the hyoid arch. At an average (BL) of 20.9 mm, ossification of the basisphenoid bone in the cranium and the suborbital bone in the orbital region occurred. Ossification of the vertebra then occurred by the formation of long pairs of ribs from the third to the ninth abdominal vertebrae, completing osteological development.

The objective of this study is to establish a methodology of bioregional approach for coastal area management as a basis for planning and design. Focusing on the bioregional approach, this study reviewed currently prevailing approaches such as watershed approach and ecological unit approach for planning and management purposes. This research placed its geographical focus on the landward watershed of the Bay of Hampyong located in Chonnam Province, dealing efficiently with shortcomings of existing researches which mainly covered seaward tidal flats without considering outside effects. The main methods of the study are classified into indoor computerized map analysis and field work. For computer analysis, printed maps and digital maps have been analysed, and GIS techniques have been utilized for its synthesis and finalizations. Field work included on-site landscape analysis and verification of a tentative place unit boundary. As a practical step, criteria for classifying bioregion were presented and the selected criteria included : topography & water ways ; roads & administrative boundaries ; habitat types ; and visual enclosure. First, based on the data of topography and water ways, broad classification work was performed and corrections were made based on data drawn out from other criteria. A tentative place unit map was drawn and revised through field visits. This study encompassed an initial but integral part for bioregional approach in landward watershed management of a coastal area. As results of the study, the necessity and efficiency of bioregional approach which considers environmental and cultural components systematically have been presented.

This descriptive longitudinal study was done to identify the ethical value of nursing students and to compare the differences of results with one year interval. The data were collected twice in 1999 and in 2000, from the 82 first year and 64 second year nursing students who have been attending at C college in Chonnam province. The analysis of data was done by frequency, mean, paired t-test, t-test, and ANOVA. The results of data were summarized as follows: 1. The total ethical value score of the first year students was 3.48 (maximum : 5) and, one year later, the score was lowered to 3.26. Especially, the degree of their ethical value was significantly decreased in the sub-areas of human-life and nurse-nursing task. 2. The total ethical value score of the second year students was 3.24 and, one year later, the score was increased to 3.39. The degree of their ethical value was significantly increased in the subarea of nurse- client relationship. 3. In the subarea of human-life, the mean score of ethical value was 3.25 and, one year later, the score was 2.95. The degree of ethical value was significantly lowered among the first year students with an utilitarian position. 4. In the subarea of nurse-client relationship, the mean score of ethical value was 3.39 and, one year later, the score was 3.67. The degree of ethical value was significantly increased among the second year students with a deontological position. 5. In the subarea of nurse-nursing task relationship, the mean score of ethical value was 3.38 and, one year later, the mean score was 3.08. The degree of ethical value was significantly decreased among the first year students. 6. In the subarea of nurse-collaboration relationship, the mean score of ethical value was 3.96 and, one year later, the mean score was 4.08 in second year students. There was no statistically significant difference. 7. The ethical values of nursing students were significantly different depending on their religion, length of study, attitude toward nursing and the experience of dying during their clinical practice.

A calf with derodidymus was delivered from a 3-year old Korean-native cow with abortion last ime at Jangheong area in Chonnam Province. The anomaly with body weight of 35 kg was born t the normal time of parturition. During the parturition, however, the calf with twin head was onfirmed and the complete amputation between fore and hind limb was inevitably carried out or safety of the dam. The calf had normal skeleton and extremities but had two heads and cervical vertebrae divided from upper thoracic part. At necropsy, there were found totally 3 pairs of ore limbs including two pairs of hypoplastic ones hided in the thoracic limb and also found one air of sternum. One head had incomplete torsion or unilateral hypoplasia of mandible with artly hypoplastic skull. There were marked fusion and torsion from cervical to 3rd thoracic vertebra. No abnormality was found on all organs in the pleural and abdominal cavities except a rectal stricture formed at 5 cm away from the atresia ani.

This study was conducted to select promising green manure crops, providing sufficient amount of nutrients for satisfying fruit tree growth, with the overwintering cover crops grown in organic orchards in 2009. The cover covers were investigated in 13 organic orchards in Chonnam province in April and June. The dry matter in cover crops observed in April and June was the highest for Lolium multiflorum Lam. and Bromus japonicus Thunb., respectively. Total N and K production in April was the highest for Lolium multiflorum Lam, Vicia hirsuta (L.) S. F. Gray and Vicia angustifolia var. segetilis (Thuill.) K. Koch., respectively, with Bromus japonicus Thunb. in June. This study showed that the leguminous crops, Vicia hirsuta (L.) and Vicia angustifolia, would be the prospective cover covers as the both crops provided sufficient amount of N and $K_2O$ into the soil. Amount of $P_2O_5$ producing from all cover crops provided less than nutrient levels than those of recommended nutrient requirement for satisfying 10- to 15-year-old fruit tree growth.

In this study, we visualized the regional migration in Korea from 2001 to 2015 using the Chord diagram which can represents amount of migration and flows at the same time. In addition, we constructed a migration network and analyzed the degree centrality of each region for identifying the main regions linking to various regions. In 2001~2005, most of population moved into Geonggi from various regions. However, the capital function was transferred to Sejong in 2011~2015, and population moving into Sejong and Chungnam was increased significantly. The main outflow of population in migration network were shown at the regions in Jeonbuk and Gyeongbuk province in 2001~2004, and recently the regions in Gyeongnam, Gyeonggi, and Seoul were identified as the main nodes in terms of outflow of population. We also focused on migration in rural area through degree centrality, and cord diagram in Chungnam, Jeonbuk, and Jeonnam where include the representative crop area. In 2015. there was the significant increase of migration from Gyeonggi to Chungnam, and internal migration within Jeonbuk increased rather than cross-border migration. In addition, migration from Jeonam to capital area decreased in 2015 but migration among cities within Jeonman increased. In particular, Yesan-gun showed the significant migration to other cities in Jeonnam. Population is necessary to develop community and sustain economic growth in rural regions. Therefore, migration is important for the transfer of manpower. The strength of this study is to approach the temporal change of migration from the viewpoint on quantitative and structural characteristics.

This study was designed to identify the relation between Self-care Agency and mental health in vocational high school students of a rural area. The subjects for this study were 210 students living in Chonnam province: the breakdown of first, second and third grade students were 74, 78 and 58 respectively. The data were collected from April 1 to 4, 1997. The instruments used in this study were the Self-Care Agency Questionnaire developed by Deneys (1981) and the simplified SCL-90 developed by Lee, H. K. (1986) for measuring Mental Health. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation using the SAS $PC^+$ Program. The results were as follows: 1. The mean score of the Self-care Agency was 2.43. 2. The mean score of Mental Health was 2.11. 3. There were significant differences in sex (t=6.13, p= .014), religion (t=4.65, p= .032), the educational level of the father (F=3.62, p= .032), economic status (F=5.90, p= .003), and school performance (F=5.94, p= .003) with respect to selfeare agenecy. 4. There were significant differences in dwelling place (t=3.18, p= .025), economic status (F=4.55, p= .012), school performance (F=6.72, p= .002) and health problems (t= 5.41, p= .021) with respect to mental health. 5. The relationship between self care agency and mental health revealed a significant correlation (r=- .24, p= .005). The results showed that a low level of self care agency has an effect on mental health. We need an effective health education program to promote mental health.
