The study is to suggest a management method for improvement of natural and cultural landscape of Hwayang valley which is degraded in Songnisan National Park. It was carried out to study original shape of landscape of it and analyse nine major properties of Hoayang Gugok, based on old literatures. The landscape of Gugok was composed of rocks and small ponds, Pinus densiflora community and most of them were degraded by the situation of covered rocks by growth of vegetation, destructed small ponds by sedimented sands and degradation of natural landscape by artificial forest. Vegetation landscape of artificial forest composed of Populus tomentiglandulosa, Robinia pseudo-acacia, Pinus koraiensis in periphery of the valley was not matched with natural landscape. The goal of landscape management was established to conserve natural and cultural landscape in Joseon Dynasty. For this, It was needed to protect landscape values of gugok through the management of vegetation and visitors. In addition, it was required to provide opportunity to easily access to the landscape of Gugok. As a management method of vegetation, it was suggested to maintain P. densiflora community and to restore artificial forest to natural forest through the density management.

We classified the forest type and figured out the ecological characteristics for each of the types in order to provide the basic informations for being induced ecologically efficient forest practice plan by vegetation units in the natural forest of Songnisan. We established the 250 sample points and collected the vegetation data of vertical distribution for each sample. A variety of multivariate statistical methods were applied to classify the forest types. The species diversity index were analyzed to estimate the stability and maturity for forest vegetation in each the type. The types were divided from two to ten clusters by cluster analysis. The appropriate number of clusters was estimated five clusters by indicator species analysis. It was verified through the multiple discriminant analysis that the estimated number of clusters had been suitable. Based on the species composition for each the type, this study site was classified into five forest types: 1) Quercus serrata and 2) mixed mesophytic forest in the valley area, 3) Q. mongolica forest in the main ridge, 4) Pinus densiflora forest in the sub-ridge extending from the main, and 5) Q. variabilis-P. densiflora forest between the sub-ridge and valley. The species diversity index of the pine forest that had been a simple species composition was the lowest while that of the mixed mesophytic forest of which the composition had been diverse was the highest. As the forest vegetation was more varied, the index showed a tendency to increase.

The purpose of this study is to survey and analyze of the visitor's cognition of admission fee collection system in National Park. To accomplish the purposes, a questionnaire survey was employed in Songnisan National Park. The contents of questionnaire consist of the socioeconomic characteristics and the types of visiting, the activity, the cognition of admission fee collection system.339 samples of total 345 respondents were used for final analysis. As a result of the analysis, the socioeconomic characteristics and the types of visiting, the visiting purpose were showed similar trends with results from other National Park visitors survey. Most of respondents didn't recognize the raise of admission fee and how to use the admission fee. And they recognized that it is too expensive. Most of respondents recognized the joint collection of admission fee but they were strong against it. About the range of cultural assets in National Park, the cognition of 'Only Buddhism's assets in temple' was almost equal with the cognition of 'It includes not only cultural assets of inside and outside temple but also thick forest in National Park'. But most of respondents were strong against the collection of admission fee of cultural assets.

By relating mineralogy, petrology and geochemistry to observed magnetic properties, an understanding of the geological factors that control magnetic signatures is obtained. Magnetic susceptibility measurements and geochemical analyses were carried out for 160 samples in the Jurassic to Cretaceous granitoids, which is distributed to Pocheon, Jipori, Geumsan, Namwon, Songnisan, Yongdam, Masan, Jindong, and Taebaeksan areas. The magnetic properties of igneous infusion in these granites reflect bulk rock composition, reduction-oxidation state, hydrothermal alteration which are controlled by tectonic setting, composition and history of the source region, depth of emplacement and nature of wall rocks.

The Response to Intervention(RTI) approaches is the method to help students who are at risk for learning difficulties in advance and provide an appropriate level of intervention. In this article, the characteristics of model RTI were reviewed for students with achievement of below basic proficiency level. We considered RTI as supporting system to document students' progress and its applicability for the general educational setting in Korean school. The tier of RTI make it possible the evidence based individual instruction and counseling, differentiated step-by step approach for students with achievement of below basic proficiency level. In conclusion, RTI can be used as educational tools for dealing with improvement of academic subjects learning, behavioral and emotional problem for students with achievement of below basic proficiency level. For building high quality implementing for RTI it is needed the collaboration of teachers, counselors and learning consultants and related educators.

Purpose: This study aimed to examine the effects of premenstrual syndrome (PMS) symptoms and coping strategies on the health-related quality of life in elementary and secondary schools female teachers. Methods: 140 female teachers in C province were recruited using a correlational study design. The measurements used were the PMS symptoms scale, the PMS coping scale and the Korean version of health-related quality of life scale. Results: The higher quality of life were predicted by the lower PMS symptoms, the higher PMS coping, the better the quality of sleep, the lower the job and life stress, and the lower work disturbance due to the PMS symptoms. These variables explained 53% of the total variance. Conclusions: For better female teachers' health-related quality of life, health care programs for managing the PMS symptoms need to be developed by considering those identified variables. For health education practice, school health teachers need to distribute health educational materials for female teachers and to provide small-group health counselling services for PMS self care.

Korean fir(Abies koreana E.H.Wilson 1920), endemic tree species of Korean peninsula, is considered as vulnerable and endangered species to recent rapid environmental changes such as land use and climate change. There are limited activities and efforts to find natural habitats of Korean fir for conservation of the species and habitats. In this study, by applying SDMs (Species Distribution Models) based on climate and topographic factors of Korean fir, we developed Korean fir's predicted distribution model and explored novel natural habitats. In Mt. Shinbulsan, Youngnam region and Mt. Songnisan, we could find korean fir's two novel habitat and the former was the warmest($13^{\circ}C$ in annual mean temperature), the driest(1,200mm~1,600mm in annual rainfall) and relatively low altitude environment among Korean fir's habitats in Korea. The result of SDMs did not include mountain areas of Gangwon-do as habitats of A. nephrolepis, because there were different contributions of key habitat environment factors, summer rainfall, winter mean temperature and winter rainfall, between A. koreana and A. nephrolepis. Our results raise modification of other distribution models on Korean fir. Novel habitat of Korean fir in Mt. Shinbulsan revealed similar habitat affinity of the species, ridgy and rocky site, with other habitats in Korea. Our results also suggest potential areas for creation of Korea fir's alternative habitats through species reintroduction in landscape and ecosystem level.

Population characteristics of Zacco koreanus were investigated at 4 stations in three National Parks of Korea from April to October 2012. Total length ranged 47mm~160 mm and weight ranged 0.50~41.50 g. Parameter b values in length-weight relationships ranged 2.883~3.497, which represent favorable conditions for habitation. Condition factor (K) had the range from 0.689 to 1.012. In relationships with sympatric fishes, the length-weight relationship (b) revealed inverse proportion to the number of species and populations. It is suggested that these differences resulted from the various factors including sympatric fishes, water temperature, seasonal changes, and surveyed stations.

The Palsangjeon Pagoda is a five-story wooden building in the Beopjusa Temple area in the Songnisan national park in Chungcheongbuk-do, Korea. According to historical records, it was constructed in either AD 1605 or AD 1626. To specify the construction year more precisely, we took 41 wood samples for tree-ring analysis during repair actions in 2013; 28 from red pine (Pinus densiflora S. et Z.), 12 from oak (Quercus spp.), and 1 from fir (Abies spp.). The tree-ring boundaries became clearly visible by smoothing their cross-sectional surface and the tree-ring widths were measured under a stereo microscope. All tree-ring series were compared with each other to establish mean chronologies, which we then compared with local master chronologies established using tree rings collected from wooden elements of the Daeungjeon Hall which is the main building in the Beopjusa Temple area. As a result, it was verified that the red pines were felled in AD 1624 and in AD 1851. Moreover, it was verified that the oaks were also felled in AD 1624 based on cross-dating with the red pine chronology. We concluded that the Palsangjeon Wooden Pagoda was constructed in AD 1626, as mentioned in the historical record (Daeungdaekwangmyeongjeonbulsangki, 1630) and the letters on a purlin on the $4^{th}$ story, using oak and red pine felled in AD 1624 and repaired later on using red pine felled in AD 1851.

The purpose of thin paper is to test difference of the two question formats, open-ended and dichotomous choice formats, in the contingent valuation method using the estimated recreational benefits. The data were collected from the visitors at the Songnisan National Park. The recreational benefit based on the equivalent variation. The two question formats, but the same content, were asked of the same individuals. In this analysis, it was used travel cost and monthly income as the exogenous variables, which assumed a linear functional form for the WTP equation. The model assumed a bivariate normal distribution on the basis of the probit and tobit model concerning the censored zero WTP. The result showed no differences in the recreational benefits from the different question formats under a same respondent. The mean benefit was estimated 25.556 Won per 5 years per visitors.
