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.

함안 묘사리 곡저평야의 하구부 토양층을 대상으로 식물규소체 분석을 행하였다. 분석결과 하부층준에서는 갈대속(Phragmites)과 재배벼(Oryza sativa)가 가장 많이 산출하였고, 기장족과 쇠풀족이 증가하여 저습한 환경에서 활발했던 농경활동을 반영하였다. 또한 고고학 발굴 결과에서도 삼국시대 수전층이 확인되었다. 전체 식물규소체 산출량은 중간층에서 가장 많고, 상부층으로 오면서 점차 증가하였다. 재배벼는 하부층에서 가장 많아서 농경층과 식물규소체 산출량은 비례하지 않았다. 그러나 재배벼는 거의 전 층준에서 연속적으로 출현하므로 전 시기에 걸쳐 농경활동이 있었을 것으로 판단된다.

This study was conducted to examine the interrelations among snack preference, purchasing behavior and intake of fifth and sixth grade students in elementary schools in Gyeongnam province. Frequency of snack intake was the highest in those who reported 'once a day' (45.6%) snack habit. Longer-time television viewers also showed higher frequency of snack intake than shorter-time viewers. Thirty-three percent of students purchased snacks by themselves and the frequency of snack purchasing had a significant positive relationship with TV watching time (p < 0.01). The main reason, place and time of eating snacks were 'hunger' (79.2%), their home environment (50.9%) and 'after school hours' (89.7%). The favorite snack was 'ice cream' and, this snack habit was significantly different by gender of the child (p < 0.01) and TV watching time (p < 0.01). 'Milk and dairy products' scored highest (3.47) in snack intake frequency among longer-time TV viewers (> 2hr) compared to shorter-time TV viewers and this difference was statistically significant (p < 0.001). The snack preference score was correlated positively (r = 0.454) with the intake frequency for snack and its explanation power ($R^2$) was 20.5%. With regard to snack purchase behaviors, the scores of 'checking the expiration date' and 'comparing the price with similar products' were high (in what group?). Female students (p < 0.001) and shorter-time TV viewers (< 2hr) (p < 0.01) had a more reasonable purchasing behavior. The total score of preference was significantly higher (p < 0.05) in shorter-timeTV viewers (< 2hr). In the correlation between snack purchasing behaviors and intake frequency, attractiveness (r = 0.208, p < 0.001) and preference (r = 0.330, p < 0.001) showed significant positive correlations. The result of regression analysis, preference only was selected ($R^2$= 0.108).

This study was carried out to investigate the cadmium level in blood by age, gender, and smoking status among 162 elderly subjects in Gyeongnam Province from September 2006 to February 2007. The cadmium level in blood was analyzed by atomic absorption spectrophotometer. Subjects were classified according to smoking status and divided into smokers and non-smokers, smoking duration, daily smoking habits, age, and gender. Mean blood cadmium levels in male and female were $0.70{\pm}0.41{\mu}g/dL$ and $0.57{\pm}0.32{\mu}g/dL$ respectively, with no significant differences between the two groups. Cadmium levels in the blood of smokers and non-smokers were $0.57{\pm}0.32{\mu}g/dL$, $0.90{\pm}0.44{\mu}g/dL$ respectively, with the cadmium level of smokers being significantly higher than that of non-smokers. In comparison by age, cadmium levels in the blood of subjects over the age 70 years and over the age 80 years were $0.91{\pm}0.44{\mu}g/dL$, $1.02{\pm}0.39{\mu}g/dL$ respectively, showing a significantly higher blood cadmium level than that of non-smokers. when compared by the amount of daily cigarette consumption, there were no significant differences in the blood cadmium level between groups. However when compared by smoking duration, the blood cadmium level for the group of smoking duration of over 10 years was $1.15{\pm}0.38{\mu}g/dL$, significantly higher than $0.67{\pm}0.31{\mu}g/dL$ for the group of smoking duration of less than 10 years. In conclusion, longer smoking duration and older aged group showed higher cadmium level in blood. For more reliable results, further study of the elements that elevate the cadmium level in blood with more subjects and study variables will be needed.

This study was conducted to investigate the eating habits and food preferences of elementary school children belong to multi-cultural families and ordinary families. The data were obtained by interview based on questionnaire from November to December in 2012. The subjects of multi-cultural families and ordinary families were 99 and 376 children, respectively. In comparison with eating habits, the ordinary children showed higher scoring in the items of eating proteins, green and yellow vegetables, and fruits or fruit juice than those of multi-cultural children. The ordinary children ate less midnight-meals than those of multi-cultural children (p<0.05). Furthermore, the ordinary children ate kimchi more frequently than the multi-cultural children. It was significantly different (p<0.05) on the items of 'eating-out types' dietary habits between two groups. Education of mothers correlated with the ordinary children's eating habits more than multi-cultural families. In the investigation of the food preference to Korean foods, 'beef and radish soup', 'pumpkin porridge', and 'wheat flakes noodles' were more preferred by children of ordinary families than by those of multi-cultural families (p<0.05). To conclude, nutritional education for their parents should be done and maintained to keep a right eating habit of children of multi-cultural families even at home.

The seasonal variation of marine algal biomass and community were studied with nondestructive sampling and quadrat method during May 2006 to April 2008 in the intertidal and subtidal zone at Yokjido. As result, total 120 species, 13 Chlorophyta, 34 Phaeophyta, 71 Rhodophyta and 2 Spermatophyta were identified in this study. The major species which contributed significantly to the total biomass were Ulva pertusa, Undaria pinnatifida, Ecklonia stolonifera, Sargassum horneri, S. serratifolium, Gelidium amansii and Prionitis cornea. The mean biomass was 235.5 g wet wt m$^{-2}$ in intertidal, 1,038.9 g wet wt m$^{-2}$ in 1 m, 1,013.1 g wet wt m$^{-2}$ in 5 m, and 19.7 g wet wt m$^{-2}$ in 10 m depths of mean sea level. Seasonal biomass change in intertidal zone, the peak season was in spring, while the lowest was in autumn. The vertical distribution of marine vegetation was characterized by Ulva pertusa - Gelidium divaricatum - Gloiopeltis furcata - Sargassum thunbergii - Hizikia fusiformis at intertidal zone, and Caulerpa okamurae - Gelidium amansii - Chondrus ocellatus - Ecklonia stolonifera - Sargassum horneri - Gracilaria textorii at subtidal zone. These result indicates that the marine algal species and biomass of 1 m and 5 m depths in subtidal zone are greater than intertidal zone, and Ecklonia stolonifera and Sargassum spp. are the dominant species of Yokjido.
