The purpose of this study was to provide basic data for maintenance and repair of the forest road surfaces using the light drop weight test (LDWT), density test, and grain size analysis at four sites in Yeongyang-gun Mt. (2011y, 2014y, 2016y, and 2017y). In terms of the density test results, the opening density in 2011 was the highest at $2.0694g/cm^3$, and the opening density in 2017 was the lowest at $1.7443g/cm^3$. The grain size analysis showed that the proportion of large aggregates was highest at the opening in 2017, and the proportion of large aggregates decreased with the delay of opening date. From the LDWT results, $E_{vd}$ (the dynamic deformation coefficient) of the 2011y forest road was $35.7MN/m^2$, 2014y was $30.5MN/m^2$, 2016y was $28.6MN/m^2$, and 2017y was $23.5MN/m^2$. The $E_{vd}$ value for the oldest forests opened with the 2011y forest road was the highest, the average $E_{vd}$ value of the center portion was $21.45MN/m^2$, the average $E_{vd}$ value of the wheel portion of the banking part was $31.31MN/m^2$, and the average $E_{vd}$ value of the wheel portion of the cut part was $36.71MN/m^2$.

This study was carried out to examine the process of plant succession through vegetation invasion and to select appropriate endemic plant species for rapid stabilization and good visual effect on cut-slopes of forest roads. Establishing total of sixty $1m{\times}1m$ sample plots. fifteen for each forest road constructed in the year of '93 (six-year-old), '95(four-year-old), '97(two-year-old), and '98(one-year-old), the ecological attributes of invading vegetation on cut-slopes were analyzed. The results are summarized as follows: 1. The rate of vegetation coverage was highly associated with soil hardness and aspect of cut-slope. Higher rate of vegetation coverage was caused by larger number of invading plant species. 2. The dominant woody species were Rubus crataegifolius, Rhus chinensis, Lespedeza bicolor, Salix hulteni, Alnus hirsuta, and Pinus densiflora. The visual attractive for the fruit of Rubus crataegifolius and the autumn coloration of Rhus chinensis was noteworthy. The dominant herbaceous species were Youngia sonchifolia, Spodiopogon sibiricus, and Lysimachia clethroides in all study forest roads. Spring flower of Potentilla freyniana and Viola rossii: summer flower of Lysimachia clethroides, Commelina communis, Glycine soja. Persicaria sieboldi, and Oenothera odorata: and autumn flower of Artemisia stolonifera and Impatiens textori were abundant and remarkable. 3. The diversity index of woody species tended to be increased as years passed after construction, and that of herbaceous species were decreased. 4. The dominance of Th of dormancy form was early high in the first year of construction, getting decreased thereafter. And that of MM + M + N was increased as years passed after construction. but that of Ch+H+G+Th+HH was decreased. 5. The degrees of succession were estimated by 359, 111, 97, and 87 for the construction year of '93, '95, '97, and '98. respectively, increased as years passed after construction.

Objectives : The purpose of this study was to examine the participation attitude of students toward pre-clinical practicums, their satisfaction with the practicums and related stress, and to investigate the influential factors for their participation attitude to practicums. Methods : The subjects in this study were three different groups of students who took pre-clinical practicums at different times. One group of students who entered college in 2008 took a practicum in December, 2009, and another group of students who entered college in 2009 took a practicum in June, 2010. The third group of students who entered college in 2010 took a practicum in June, 2011. Results : 1. As for participation attitude, the students who completed a practicum before they underwent field training in the second semester of their sophomore year got a higher mark of 3.44(p<0.05). 2 Concerning the operation of practicum, they felt a lot of stress when they took a practicum before they underwent field training in the first semester of their sophomore year and when they had no dental experience(p<0.001). 3. Regarding satisfaction with practicum, they scored higher when they took a practicum before they underwent field training in the second semester of their sophomore year(p<0.05). And the students who were more gratified with dental experience expressed better satisfaction(p<0.001). 4. As to the influential factors for the participation attitude of the students, those who were more satisfied with the content of practicum, the operation of practicum and evaluation took a more positive participation attitude(p<0.001). More stress about the operation of practicum and more stress about evaluation exerted a greater negative influence on participation attitude(p<0.05). Conclusions : Given the findings of the study, a pre-clinical practicum should be offered before field training is provided in the second semester of the sophomore year in order to ensure the efficiency of education, and a wide variety of information should be offered so that students could gain dental experience before they take a practicum.

The purpose of this study was to examine the state of convenience facilities for the disabled in dental institutions in an effort to provide some information on the improvement of the accessibility of disabled people to dental institutions. A survey was conducted on the licensed dental institutions in the city of Cheongju, North Chungcheong Province, from March to April, 2011. The findings of the study were as follows. The dental offices were the majority of the dental institutions investigated, and for the establishment of the dental institutions. Some of the offices were established before 1990, and some were established in 2011. The time period of establishment varied within the offices. As for the location of the dental institutions within the buildings, they were mostly on the second or third floor. Regarding the convenience facilities for the disabled, the most installed convenience facilities were boardwalks and elevators, and the least installed ones were parking lots and restrooms for the disabled. The hospitals and public dental centers were equipped with all the convenience facilities investigated in this study. Overall, the dental institutions that were established in and after 2006 were equipped with more convenience facilities than the dental institutions that were established before 1990. And the dental clinics that were on the third or higher floor were more equipped with elevators and outdoor slope ways than those that were on the first or second floor. Therefore the revision of the law is required to urge even the primary dental institutions to compulsorily install the convenience facilities. The findings of the study are expected to make a contribution to the improvement of the accessibility of disabled people to dental institutions.

90년대 이후 국내에는 국립중앙박물관을 포함하여 많은 박물관 관련시설이 건립되었거나 건립 중에 있으며, 앞으로도 지역적 여건과 특수성에 부합하는 미술관, 전시관, 홍보관 등 다양한 전시 관련시설들이 요구될 것으로 예상된다. 양적인 면에서 보더라도, 아직 선진외국의 수준에는 미치지 못하지만 현재 약 400여개(등록,미등록 포함)의 박물관이 전국적으로 개설되어 있다. 이러한 현상은 우리가 다양한 사회문화적 욕구를 수용해야 하는 시기에 이르렀으며, 동시에 단순히 보여주기만 하는 소극적 자세의 박물관으로부터 보다 다양하고 의미 있는 경험을 제공해주는 적극적 자세의 공공박물관으로의 인식전환이 요구되는 시점에 이르렀다는 것을 의미한다. 특히 현대적 개념의 박물관은 시대적 변화에 따라 그 사회적 역할이 달라지고 있다. 즉 과거 고전적 의미의 박물관이 수집과 보존을 중심으로 이루어져서 사실상 일반대중과의 관계는 그다지 중요하게 고려되지 않았던 것이 사실이다. 반면에 오늘날의 박물관은 이러한 기본적인 기능과 함께 전시와 문화적 교육에 보다 중점이 주어지는 방향으로 전환되는 진정한 의미의 공공문화시설로서의 역할이 강조되고 있는 것이다. 이 글은 박물관건축의 세계적 성공사례들의 특성을 파악하고 분석하여 국내의 박물관건축의 발전에 도움을 주고자 한다.
