Heavy snowfall was occurred over the south-western part of the Korean Peninsula called as Honam Districts, on two days from 21 December 2005. The development mechanism of snowfall and its characteristics were analysed using observation and numerical data provided by Korea Meteorological Administration. In comparison with other years Arctic air mass developed and maintained during all December 2005 due to active planetary waves with three branches. And jet streams at lower and higher levels make easy development of snow convection cells. Especially thermal low induced by mesoscale heat and dynamic sources, also help the developments of convection cells in strong ascension. The understanding the relation between synoptic and mesoscale circumstance, therefore, is also important to predict the heavy snowfall and to prevent the disaster.

A stable method for strain distinction using viral RNA 1 structures analyses was developed and compared with the combined RT-PCR and RAPD methods. Seven out of 61 random primers were found to be polymorphic based on RAPD analysis resulting on the differentiation of the 33 BaYMV isolates into four distinct groups according to geographical districts. The first and largest group includes 13 isolate and consists mainly of two-rowed malting barley in Haenam area. The second group had ten collections from inland in west southern. The third group had seven isolates from west southern coastal region, where mainly six-rowed naked barley is cultivated. The last fourth group included three isolates from Gyungnam region in east southern area. Conclusively, RNA 1 analysis proved to be stable and efficient method for strain distinction for Korean BaYMV isolates. Further, results of pathogenicity and RNA 1 structure analyses revealed four groups BaYMV strains and were distributed all over Korea, represented by Naju, Haenam-okcheon, Iksan and Milyang.

이 연구는 지역균열이라는 우리나라의 정치 현실이 국회의원선거구 획정에 개입되었는지를 확인하고, 그에 따른 문제점을 게리맨더링과 투표 등가치성을 중심으로 분석하였다. 제헌의회 이래 국회의원선거구 획정에서 게리맨더링과 투표 등가치성 훼손에 대한 논란은 지속되었고, 더욱이 소선거구 단순다수제 체제로 인해 선거구 획정이 선거 결과와 공정성에 큰 영향을 주고 있다. 특히 제18대와 제19대 총선의 선거구 획정은 부당한 지역균열정치의 간섭이 이루어진 것으로 의심되는데, 지역 그리고 선거구별 인구규모에 비해서 새누리당이 우세한 영남과 민주통합당이 우세한 호남에서 선거구 수는 최대한 확보되었고, 반면 경기도를 비롯한 다른 지역에서는 선거구 증설이 억제되었다. 이처럼 양당이 서로 확실하게 우세한 지역의 기득권을 보장해 주고, 불확실한 지역에서만 제한적으로 경쟁하는 구조의 선거구 획정은 게리맨더링에 담합한 것이라고 할 수 있으며, 결과적으로 투표 등가치성이라는 선거의 평등원칙과 헌법적 가치가 훼손되었다.

Humans are exposed to toxic element arsenic (As) from air, food and water The current study was performed to investigate the levels of arsenic in the internal organs (liver, kidney cortex, lung, cerebrum. abdominal muscle and abdominal skin) and to find out correlation with age and interrelationship between tissues in Korean human bodies who had lived in Seoul or Gyeonggi Province and Honam district. The tissues from 43 Korean cadavers were digested with microwave digestion system and arsenic was determined by inductively coupled plasma mass spectrometer (ICP-MS). The mean recovery percentages of arsenic In liver were about 80％ and artenic concentrations in human tissues were almost uniform. The mean level of arsenic in internal tissues were at follow ; liver 44.556${\pm}$25.199 ppb, kidney cortex 42.652${\pm}$22.082 pub, lung 31.020 ${\pm}$ 17.504 ppb. cerebrum 35.703 ${\pm}$22.191 ppb, muscle 43.413${\pm}$26.619 ppb and skin 42.106${\pm}$25.8,11 ppb. No significant difference was found in the levels of arsenic between sexes. Meanwhile significant differences between districts where they had lived were found in all tissues tested. The levels of arsenic in the tissues of cadavers who had lived in Seoul Gyeonggi Province were higher than those of Honam district. In addition a positive correlation between As concentration and age was observed only in the cerebrum (p < 0.05). A significantly high correlations between tissues were observed in all tissues tested. This result also shows that the distribution of arsenic is uniform in internal tissues.

The authors, to collect some necessary data to promote correcting the toothbrushing method, the most basic home dental care, and to arrest the attention to the dentifrices in Korea, observed and evaluated the cervical abrasion experience rate in 8,000 Korean male and female adults from 19 to 52 years in the age, which had been extracted by the stratified random sampling method. The obtained results were as follows; 1. Cervical abrasion experience rate was 18.6% in Korean adults. 2. Cervical abrasion experience rate in male adults was higher than that in female adults. 3. Cervical abrasion experience rate was gradually increased by ageing. 4. It seemed the cervical abrasion experience rates in the adults in Honam and Youngnam district to be higher than those in the other districts. 5. In Korean adults, the further detail inveatigations into the cervical abrasion were required.

Citizen participation or resident participation is perceived as an effective way to correspond to the diverse urban problems, especially in the area of residential environment improvement projects and community activities. As the leading city of the Honam region and a core middle city leading the development of the southwestern region, Gwangju city is planning and under-developing new Housing Complexes and Urban Renewal Projects. The purpose of this study is to identify the perception of Gwangju citizens on resident participation in community activities to suggest diverse strategies for improving quality of citizen's life and making better living environment. For the research purpose, 1,380 questionnaires were distributed to the Gwangju citizens who live in 5 autonomous districts -Dong-gu, Seo-gu, Nam-gu, Buk-gu, and Gwangsan-gu- and 601 were used in data analysis. Although citizens in Dong-gu showed the lowest settlement consciousness, they required the highest level of need for resident self-help activities. Contrastingly, Seo-gu showed the highest level of settlement consciousness and the lowest need for resident self-help activities. Based on the results, high quality community facility should be provided to promote residential satisfaction and consciousness of residential participation and self-help activity must be improved. And also, diverse strategies for resident participation including development of resident education programs and search for regional resources should be covered in further research.

Heavy metal pollution has become a serious health concern in recent years. Dogs are a very good indicator of the pollution load on the environment. They share people's environment and are exposed to the action of the same pollutants. This study estimated the heavy metal contents in the serum of dogs in domestic districts, and assessed the age, sex, feeding habits, living area, breeding environment and smoking habit of the owners. The findings suggest that dogs can be used to monitor the environmental quality of heavy metals. The mean concentrations of heavy metals in the dog serum from 204 samples (108 male and 96 female) were 0.22${\pm}$0.01 $\mu$g/ml, 0.24${\pm}$0.04 $\mu$g/ml, 0.61${\pm}$0.08 $\mu$g/ml, and 0.50${\pm}$0.06 $\mu$g/ml (for Cd, Hg, Pb, and Cr), respectively. Concentrations of Pb, Cd, Hg, and Cr in the dog serum were higher in Yeongnam including Ulsan, and Seoul higher than those of Chungchong and Honam, especially Pb concentration, which was significantly higher (p<0.01). Concentrations of Cd, Hg, Pb, and Cr in serum, were increased by age (p<0.05). When commercial pet food was provided to dogs, Cd and Cr concentrations were significantly higher in dog serum than dogs fed a human diet (p<0.01 in Cd and p<0.05 in Cr). Heavy metal concentrations of dogs owned by smoking owners, were higher than non-smoking owners although there was no significant difference.
