  • Twenty-nine wetlands (20 river type and 9 lake type wetlands) in Gyeongsangnam-do were investigated to understand the characteristics of fish assemblages by the wetland type and to suggest management strategies. As a result, $10.3{\pm}4.8$ species were collected from river type wetlands on average (${\pm}SD$) and $9.1{\pm}4.1$ species from lake type wetlands. Thus, there was no significant difference in the number of species between them (Mann-Whitney U test, P>0.05). However, the species that constitute the fish assemblage showed statistically significant differences between the two wetland types (PERMANOVA, Pseudo-F=2.9555, P=0.007). Furthermore, the species that contribute the most to each type of fish assemblage were Zacco koreanus (river type, 28.51%) and Lepomis macrochirus (lake type, 23.21%), respectively (SIMPER). The results of the NMDS analysis using the fish assemblage by place classified the species into three groups (river type, lake type, and others). The current wetland management is only focused on endangered species, but this study shows a difference in fish assemblage by wetland type. Therefore, a management system based information on endemic species, exotic species and major contribution species should be provided. Furthermore, the classification of some types of wetlands based on the present topography was found to be ambiguous, and wetland classification using living creatures can be used as a complementary method. This study has limitations because only two types of wetlands were analyzed. Therefore, a detailed management method that can represent every type of wetland should be prepared through the research of all types of wetlands in the future.

  • This study was to analysis perception about Teaching & Learning Support System of the school of Rural Areas in Korea. In order to accomplish the study purpose, the study conducted a research through Web Survey method and examined their recognition. Major findings of this study were as follows: First, Student was satisfied with TLSS of the school of Rural Areas in Korea. Students would like to 'using e-learning with Electronic board and Tablet PC' among program contents. But the system' utilization was low. However, 90% of the students wanted that teacher usually using the FASTEL. Second, Teacher satisfaction was lower compared to the students is relatively. Teachers prefer 'various after school program' to 'using e-learning with Electronic board and Tablet PC'. However, learning effective of using FASTEL system was a 73.8% of teachers are effective is aware and had. Third, 35% Students recognized that are using the pastel system, frequently, On the other hand, the teachers are 60% and to recognize that there was. The reason doesn't the system to good use is slow wireless. Still, e-learning classroom infrastructure for satisfaction was high. Fourth, Teachers recognized students and the pastel system interaction than other e-learning system high. FASTEL System used in the most uncomfortable things on e-learning classroom Wireless Internet phenomena and lost content lacking, in order, I was told. Therefore, there is an urgent need to improve to include Wireless Internet speed improvements and various content added support, easy-to-use instructional tools Add support order selected.

  • This study is designed to examine the effects of information source effects of the word mouth have on the formed expectations for the private institution and to explore the formed expectations' effects on the actual sales of the educational service. Moreover, its purpose is in analyzing what medication effects the pre-conceived expectation has on selecting the educational service. After testing hypothesis, the results showed that the source effects of the information from word of mouth had a significant effect on the expectation factors, in terms of expertise, similarity, likability and familiarity expectation factors. However, it was found that effect was not significant for the truthfulness. The significant result was found on the expectation factors before visiting the private institution on selecting educational service, indicating a positive effect. As for the influence of source of the word of mouth information on selecting educational service, the results from the mediation effects of the expectation factors on selecting the educational service showed that for expectation factors, expertise had the partial mediation effect, truthfulness, perfect mediating effect, similarity, partial mediation effect, likability, perfect mediating effect, and familiarity, perfect mediating effect. A test of the mediating role of attribute expectations in the influence of WOM message source attributes on educational services choices showed the following: 1) It was proven that attribute expectations played a partial mediating role in the influence of expertise and similarity, respectively, on educational services choices. 2) On the influence of trustworthiness, likability, and familiarity on educational services choices, respectively, attribute expectations had a full mediation effect. This research differs from the previous ones, which focused only on consumer satisfaction with educational services offered by private educational institutions in that it covers not only the influences of both WOM source attributes and key component factors of educational services on both educational services choices and satisfaction with such services but also the influence of WOM source attributes on attribute expectations prior to the first visit to a particular private educational institutions, and in turn the influence of such attribute expectations on educational services choices. Most particularly, the significance of this study lies in the fact that in an effort to more clearly explain the causal relationship between WOM source effects and educational services choices a test of the mediating role of attribute expectations was conducted. Although the research seems simple, some theoretical implications can be drawn as follows: WOM message source effects on educational services choices were positive and moreover these positive impacts are likely to be reinforced by means of the mediating variable of attribute expectations.

  • Gangnam-gu, where the survey of residents' consciousness has been made in this study, is the district shows the highest rate of the energy consumption and greenhouse gas emission per unit area except some industrial districts such as Gwangyang, Ulsan, and Pohang. The greenhouse gas emission amount of Gangnam-gu is 4,863,765 $tCO_2$ which accounts for 10 % of the total discharging amount of Seoul, 50,330,356 $tCO_2$, which is ranked the top greenhouse gas emission rate in the commercial category and the 2nd place in the household category. The average recognition rate for the 5 subjects of the global warming phenomenons has indicated to be 83.58%. A survey questioning about the main agent to reduce the greenhouse gas, in all age groups except 20s have replied that it should be done by themselves, the residents of Gangnam-gu. For the question of the role of local government to respond to the climate change, the necessity of establishing infrastructure which is suitable for walking and biking. For the other question about the educational facilities to cope with the climate change, many answered the relevant education should be processed from the middle and high schools. For the practical activities in daily life to respond to the climate change, many replies have shown that the energy and resource conservation has been practiced pretty well broadly, but the ecomileage (former carbon mileage) has not been practiced well. Also, many replies have pointed that there were no benefits or rewards for the people who practiced the eco-mileage in their daily lives, which indicates that a kind of incentive is necessary for the efforts to respond to the climate change from the local government to execute the policy substantially and effectively. This study has the purpose to search the political countermeasures to improve the potentiality to reduce the green house gas emission rate through the residents conscious survey about climate change and the political solution by the local government to improve the certain items which showed the lower awareness rate.

  • This study aimed to investigate the tectonic setting of the volcanic edifice at Mt. Baekdu by analyzing petrochemical characteristics of Holocene felsic volcanic rocks distributed in the Baekdusan stratovolcano edifice and summit of the Cheonji caldera rim, as well as Pleistocene mafic rocks of the Gaema lava plateau and Changbaishan shield volcano edifice. During the early eruption phases, mafic eruption materials, with composition ranging from alkali basalt to trachybasalt, or from subalkaline (tholeiitic) basalt to basaltic andesite formed the Gaema lava plateau and Changbaishan shield volcanic edifice, whereas the Baekdusan stratovolcano edifice and Holocene tephra deposits near the summit of the Cheonji caldera comprises trachytic and rhyolitic compositions. Analysis results revealed bimodal compositions with a lack of 54-62 SiO2, between the felsic and mafic volcanic rocks. This suggested that magmatic processes occurred at the locations of extensional tectonic settings in the crust. Mafic volcanic rocks were plotted in the field of within-plate volcanic zones or between within-plate alkaline and tholeiite zones on the tectonic discrimination diagram, and it was in good agreement with the results of the TAS diagram. Felsic volcanic rocks were plotted in the field of within-plate granite tectonic settings on discrimination diagrams of granitic rocks. None of the results were plotted in the field of arc islands or continental margin arcs. The primitive mantle-normalized spider diagram did not show negative (-) anomalies of Nb and Ti, which are distinctive characteristics of subduction-related volcanic rocks, but exhibited similar patterns of ocean island basalt. Trace element compositions showed no evidence of, magmatic processes related to subduction zones, indicating that the magmatic processes forming the Baekdusan volcanic field occurred in an intraplate environment. The distribution of shallow earthquakes in this region supports the results. The volcanic rocks of the Baekdusan volcanic field are interpreted as the result of intraplate volcanism originating from the upwelling of mantle material during the Cenozoic era.

  • This study was performed to investigate the performance state and improvement countermeasure of Primary Health care Posts(PHPs). The operation reports of PHPs(1996 330 PHPs, 1999 313 PHPs) located in Kyongsangbuk-Do and data collected by self-administered questionnaire survey of 280 community health practitioners(CHPs) were analyzed. The major results were as follows: Population per PHP in 1999 decreased in number compared with 1996. But population of the aged increased in number. The performance status of PHP in 1999 increased compared with 1996. A hundred forty one community health practitioners(50.4%) replied that the fiscal standing of PHP was good. Only 1.4% replied that the fiscal standing of PHP was difficult. For the degree of satisfaction in affairs, overall of community health practitioners felt proud. The degree of cooperation between PHP and public health institutions was high and the degree of cooperation of between PHP and private medical institutions was high. The degree of cooperation between PHP and Health Center was significantly different by age of CHP, the service period of CHP, and CHP's service period at present PHP. Over seventy percent of CHPs replied that they had cooperative relationship with operation council, village health workers, community organization. CHPs who drew up the paper on PHP's health activity plan were 96.4 % and only 11.4% of CHPs participated drawing up the report on the second community health plan. CHPs who grasped the blood pressure and smoking status of residents over 70% were 88.2%, 63.9% respectively and the grasp rate of blood pressure fur residents were significantly different according to age and educational level of CHP. CHPs received job education in addition continuous job education arid participated on research program in last 3 years were 27.5%, respectively. CHPs performed the return health program for residents in last 3years were 65.4%. Over 95% of CHPs replied that PHPs might be necessary and 53.9% of CHPs replied that the role of PHPs should be increased. CHPS indicated that major reasons of FHPs lockout were lack of understanding for PHP and administrative convenience, CHPs were officials in special government service governors intention of self-governing body. CHPs suggested number of population in health need such as the aged and patients with chronic disease, opinion of residents, population size, traffic situation and network in order as evaluation criteria for PHP and suggested results of health performance, degree of relationship with residents, results of medical examination anti treatment, ability for administration and affairs in order as evaluation criteria for CHP. CHPs replied that the important countermeasures for PHPs under standard were affairs improvement of PHPs and shifting of location to health weakness area in city. Over 50% of CHPs indicated that the most important thing for improvement of PHPs was affairs adjustment of CLIP. And CHPs suggested that health programs carried out in priority at PHP were management of diabetes mellitus and hypertention. home visiting health care, health care for the aged. The Affairs of BLIP should be adjusted to satisfy community health need and health programs such as management of diabetes mellitus and hypertention, home visiting health care, health care for the aged should be activated in order that PHPs become organization reflecting value system of primary health care.

  • 1997년 IMF 경제위기 이후 한국사회의 뚜렷한 변화의 하나는 빈부격차의 확대와 함께 사회계층의 양극화가 진행되고 있다는 점이다. 이 논문의 목적은 사회적 양극화의 주요 원인은 무엇이며, 사회적 양극화가 공간적으로는 어떻게 나타나는가를 서울을 사례로 하여 규명하는 데 있다. 서구 선진자본주의 국가에서 사회적 양극화에 대한 논의는 이미 1990년대 초 세계화 또는 세계도시가 주요한 연구주제로 등장하면서 시작되었다. 1980년대 이후 선진자본주의 국가를 중심으로 한계에 도달한 포드주의 축적체계가 포스트 포드주의로 급속히 전환되면서 사회적 양극화가 자본의 유연화 및 세계화 전략과 맞물리는 현상으로 인식되었기 때문이다. 이런 점에서 최근 전개되고 있는 한국의 사회적 양극화는 서구 선진국과 유사하다. 1997년 경제위기 이후 세계화가 급속히 진행되는 가운데 지식기반경계의 대두로 고소득 전문직이 등장하는 반면, 중산층의 몰락과 더불어 임시적 고용이 확대되고 실업이 만성화되는 등 자본의 세계화와 유연화 과정에서 나타나는 양극화 양상이 보이기 때문이다. 이와 같은 맥락에서 한국의 사회적 양극화는 이미 1990년대 초부터 진행되어 왔으며, IMF 경제위기는 단지 그러한 사회적 양극화를 급속히 진행시키는 방아쇠 역할을 하였다고 할 수 있다. 그러나 양국의 사회적 양극화는 직업구조와 임금소득의 격차만으로 설명하기 어려운 또 다른 특성을 갖는다. 왜곡된 시장구조에서 무엇보다도 부동산과 같은 자산소득의 격차가 큰 역할을 하기 때문이다. 서울은 이와 같은 한국의 사회적 양극화가 한 도시 내에서 전형적으로 전개되는 곳이라고 할 수 있다. 한국 내 어떤 도시보다도 세계화되어 있고 전문지식을 기반으로 하는 산업이 발달하고 있기 때문이다. 서울의 사회적 양극화는 공간적으로도 나타난다. 일반적으로 서울은 크게 주거지로서는 공동화되고 있는 중구 종로구 용산구 등 사대문안의 구도심지역, 강남구 서초구 송파구 등을 중심으로 한 1970년대 이후 계획적으로 계발된 이른바 강남의 신흥주택 및 신산업 지역, 영등포구 구로구 금천구 성동구 동대문구 등 제조업 중심의 구 산업 및 저소득층 주거지역 그리고 그 나머지 강북 강서 강동 등의 전형적인 주거지역 등 4개 유형으로 지역이 구분된다. 그러나 IMF 경제위기 이후에 강남구 서초구 송파구를 중심으로 하는 고소득증의 주거지와 그 나머지 주거지로 공간적 양극화가 이루어지고 있다. 사회적 양극화의 이와 같은 공간화 과정에는 자산소득의 격차를 확대하는 강남구 서초구 송파구의 높은 지가 및 아파트 가격이 중요한 역할을 하고 있다. 높은 부동산 가격이 이 지역에 대한 일종의 진입장벽을 참음으로써 고소득층에 의한 공간독점을 가능하게 하기 때문이다. 공간적 양극화를 촉진하는데는 지하철 및 문화복지시설의 집중 둥 불균형적인 공공투자와 강북에서 이전한 명문고등학교를 중심으로 형성된 8학군 등 양호한 교육환경 또한 중요한 역할을 하고 있다. 서울의 사례에서 확인할 수 있듯이, 한국에서의 사회적 양극화는 직업구조와 임금소득이라는 일반적인 요인 외에도 부동산 가격 및 소득 그리고 생활인프라의 격차를 통해 공간적 양극화물 야기하고 있다. 이러한 현상이 한국내 다른도시에서도 전개되고 있는지, 공간적 양극화로 인한 도시문제는 무엇이고 대처방안은 무엇인지 등에 대해서 후속연구가 요구된다.

  • Residential differentiation is an academic theme which has been given enormous attention in urban studies. This is due to the fact that residential segregation can be seen as one of the best indicators for socio-spatial dialectics occurring on urban space. Measuring how one population group is differentiated from the other group in terms of residential space has been a focal point in the residential segregation studies. The index of dissimilarity has been the most extensively used one. Despite its popularity, however, it has been accused of inability to capture the degree of spatial clustering that unevenly distributed population groups usually display. Further, the spatial indices of segregation which have been introduced to edify the problems of the index of dissimilarity also have some drawbacks: significance testing methods have never been provided; recent advances in spatial statistics have not been extensively exploited. Thus, the main purpose of the research is to devise a spatial separation measure which is expected to gauge not only how unevenly two population groups are distributed over urban space, but also how much the uneven distributions are spatially clustered (spatial dependence). The main results are as follows. First, a new measure is developed by integrating spatial association measures and spatial chi-square statistics. A significance testing method based on the generalized randomization test is also provided. Second, a case study of residential differentiation among groups by educational attainment in major Korean metropolitan cities clearly shows the applicability of the analytical framework presented in the paper.

  • Lichen thalli of Dirinaria applanata heavily colonized on the twigs of dead or dying Rhododendron trees in Solok island, Jeonnam province in Korea. Pathogenesis of the lichen on the trees was investigated to find out the possibility of lichen as a causal agent. Histological examination of the lichen colonized twigs was attempted with differential staining technique. Lichen-forming fungus colonized only on the surface of bark and there was no direct penetration of fungal hyphae into the plant tissues. Symbiotic algae of the lichen was also examined. The isolated algal cells were inoculated on artificially induced wounds of the healthy trees. Histological examination of the inoculated tissues showed that some algal cells were successfully colonized inside the tissues without any pathogenic symptoms, even 2 months later, The extract of the lichen thalli was also examined using 10% of DMSO solution. Treated tissues showed no pathogenic symptoms, even 4 weeks later. The results suggested that the lichen was not directly involved in the death of the trees.

  • As the public Japanese art, print can be said to have started from Ukiyo-e print of Edo period(江戶時代, 1603~1867). Ukiyo-e(浮世繪) print, which 3 persons jointly produce, henceforth has gradually declined since the meiji period(明治時代, 1868~1912) due to the development of new print technique and introduction of western art. Since then, during the daiso period(大正時代 1912~1926), creative print movement grew up. Creative print is, differently from Ukiyo-e print, to be produced by one person, from the original picture to print, focusing on creating the artist's own work by being the main agent of the work. During before and after 1900s, print was evaluated low in Japan, compared to western painting, sculpture, etc. Nevertheless, the facts that several Japanese print artists received awards from international exhibits since 1950s became a big topic internationally, which became an opportunity to hold Tokyo International Print Biennale in 1957 in Japan, the first international art festival. From then on, print was recognized as an art genre while new recognition on it was gradually accepted also in Japan. In 1970, a controversy on it arose, while the characteristic of print as a medium of modern art became strong, accordingly, a controversy on it arose. However, in 1980, it firmly established itself as an art genre by overcoming the crisis through various efforts in the dimension of print artists and university education. Since then, print artists who produce new works with completeness by applying traditional technique and modern expression mode emerged, and until now Japanese modern print art is highly recognized by the world through the continuous overseas activities, research on print art, and cultivation of young print artists. This research looked back on the historical process when Japanese modern print art was created, which represents Asia, and investigated the cause that it could have win an international fame.
