This paper briefly reviews the history of the Korean geophysics and analyze the current status of geophysical researches. And the future prospects of geophysics are discussed based on social demands for the science and technology in Korea. About thirty universities offer geophysics courses in their academic curricula. Although the number of Ph.D. graduates in geophysics had been small until the year of 1990, but is rapidly increasing. In recent years about $7{\sim}8$ Ph.D's are produced every year. The major geophysical methods used in Ph.D. theses are seismic, electrical and electromagnetic methods, and earthquake waves and research themes are computational geophysics, which involve data processing, modelling, inversion and tomography, geological structures, and paleomagnetic studies in the order of numbers. The Solid Earth Geophysics is generally distinguished in two categories such as "Global Geophysics" and "Exploration Geophysics". However, they are intimately connected, and overlap in many sectors, especially in large scale research projects. The global geophysics has a more academic and general scientific meaning, and several research groups in Korean universities are carrying out the earthquake seismology and paleomagnetic studies. On the other hand the exploration geophysics focuses on practical application of geophysical concepts, and the public research institutes conduct large projects for exploration of energy and mineral resources and to cope with environmental and natural disaster problems. The geophysical studies for local geology and regional crustal structure utilize various survey methods and usually cover both academic and exploration purposes. The computational geophysics constitutes the indispensable theoretical backgrounds for all geophysical sectors. Many young Korean geophysicists, who have strong background in mathematics and physics, devote to the computational geophysics and several groups have made the internationally highest level achievements. But, Korean geophysicists have to expand their research interests to include more global-scale, high-tech researches and collaborative works with various other science groups.

This study was designed to provide basic visiter information for establishing effective park management strategies. A questionnaire survey was at major entry points in Hallasan National Park(Eorimok and Youngsil). 237 random samples among the visitors on the way back home from their visit were chosen to represent general visitor population. As for the results, visitors' recreational satisfaction level with the area was relatively high. The majority of the visitors were satisfied with 20 uses and management related attributes provided by Hallasan National Park system. However, considering lack of sense of hygienic sanitary facilities, consequential deterioration of natural and cultural resources, and entrance fees as well as other costs, there needs to be a managerial priority on visiter service.

The genes encoding non-specific lipid transfer proteins (nsLTPs), members of a small multigene family, show a complex pattern of expressional regulation, suggesting that some diversification may have resulted from changes in their expression after duplication. In this study, the evolution of nsLTP genes within the Poaceae family was characterized via a survey of the pseudogenes and unigenes encoding the nsLTP in rice pseudomolecules and the NCBI unigene database. nsLTP-rich regions were detected in the distal portions of rice chromosomes 11 and 12; these may have resulted from the most recent large segmental duplication in the rice genome. Two independent tandem duplications were shown to occur within the nsLTP-rich regions of rice. The genomic distribution of the nsLTP genes in the rice genome differs from that in wheat. This may be attributed to gene migration, chromosomal rearrangement, and/or differential gene loss. The genomic distribution pattern of nsLTP genes in the Poaceae family points to the existence of some differences among cereal nsLTP genes, all of which diverged from an ancient gene. The unigenes encoding nsLTPs in each cereal species are clustered into five groups. The somewhat different distribution of nsLTP-encoding EST clones between the groups across cereal species imply that independent duplication(s) followed by subfunctionalization (and/or neofunctionalization) of the nsLTP gene family in each species occurred during speciation.

Purpose: The purpose of this study was to identify influencing factors on rehabilitation adherence in stroke patients. Methods: This study was a descriptive survey. A structured questionnaire was used for face-to-face interviews with a convenient sample of 192 subjects, who were admitted in 5 rehabilitation hospitals located in G metropolitan city. Results: The score of rehabilitation motivation in the subjects was a mean of $2.04{\pm}0.35$, self-efficacy $6.22{\pm}2.32$, family support $3.40{\pm}0.82$ and rehabilitation adherence $3.08{\pm}0.41$. The rehabilitation adherence was a statistically significant difference according to the education level (F= 3.40, p= .035), marital status (F= 4.04, p= .019), number of personal insurance policies (K= 9.80, p= .020), location of paresis (F= 2.72, p= .046), and status of current smoking (M = 657.00, p= .001). There was significant correlation among degree of rehabilitation adherence, rehabilitation motivation (r= .30, p< .001), self-efficacy (r= .14, p= .046) and family support (r= .18, p= .011). Rehabilitation motivation (${\beta}=0.19$, p= .007), self-efficacy (${\beta}=0.14$, p= .035), marital status (${\beta}=0.14$, p= .038), number of personal insurance policies (${\beta}=-0.15$, p= .045) and location of paresis(${\beta}=-0.15$, p= .028) were identified as significant predictors. This model explained 22.6% of variance in rehabilitation adherence (F= 5.92, p< .001). Conclusion: There is a need to develop an effective intervention for rehabilitation adherence improvement considering the identified variables in this study.

This study is to suggest landform and environmental problems of border region of N. Korea and China by analyzing results of field work for the Dumangang and the Amnokgang from year 2000 up to year 2016. By the social system in North korea, access of study material is possible with satellite image and published statistical data, but impossible direct data collection. We gathered field work data on landform and environment in border Region of N. Korea and China. Before field survey, we analysed geometrical landform and geology using DEM and digital geology map. We analyzed landform and environmental problems occurring in upper, midstream, and downstream region of the Dumangang and the Amnokgang using field work data. Resultingly, this study will be expected to support as basic data for resonable management on natural resources and empirical research activities on North Korea.

This study dealt with the Kogi River, located in Kaizuka City, Osaka, which has experienced different improvements from the upper through the lower regions, aimed at revealing temporal relations between residents and the river, as well as probing future problems and directions regarding the river in the suburban area, by conducting a survey of local residents. The result showed that, in the upper region where nature remains in its natural state and the good water quality has been maintained, the relations between the residents and the river continued until around 1965; meanwhile in the middle region the relations have been disappearing since about 1955, and in the lower region where the stream has been repeatedly rehabilitated since 1955, there are fewer involvements of the people with the river. It also revealed that the weaker the relations between people and the river became, the larger the number of residents, even in the upper region, who became concerned over the deteriorating river environment after about 1975, and that in the middle and lower areas, about a decade earlier than in the upper area, the number of those who were aware of the environmental deterioration began to increase. Consequently, with an eye to resuming the relations between people and the river in an suburban area, their future challenges would be the space improvements depending on the environmental characteristics of the area; for example, the recovery of grassy banks for the purpose of protection in the lower region; the preservation and maintenance of many waterside woods as well as the creation of open spaces utilizing the river banks in the middle area; and throughout the whole region, the establishment of a system in which the relations between man and the river can be passed down to future generations, by utilizing the local human resources including those who know the former river landscapes or about the playing in and around the river.

In this study, warmth and cold-indices were calculated from the climatic records for 30 year from 1931 to 1960 observed at the 80 weather stations as illustrated in Table 1 and Figs. 4 and 5. Iso-warmth index and iso-cold index lines were carefully tracked. However, subjectivity might be involved in this delimitation. The well recognized phenomena of phenology, the natural distribution of specified tree species and potentially cultivable zones of some species of economic importance were discussed with regard to these indices. It is seemed that the forest zones of Korea accepted commonly by foresters and researchers were more rationally matched with the cold indices rather than warmth indices. The forest improvement works by introduction, planting works and other related fields could be refered to these data.

We report previously unrecognized flowering plants of Lao PDR found during a botanical survey of Lao PDR in 2015-2016. We found Phyllagathis tuberosa (C. Hansen) Cellinese & S. S. Renner (Melastomataceae) and Tolypanthus pustulatus Barlow (Loranthaceae) in the Phou Khao Khouay National Biodiversity Conservation Area (PKKNBCA), previously only known from type localities in Thailand. This is the first report of Phyllagathis tuberosa and the genus Tolypanthus in the Lao PDR. We also found Lonicera bournei Hemsl. (Caprifoliaceae) in the proposed Phosabous National Protected Area (PNPA) of Xiangkhoang, neglected with regard to the flora of Laos since its initial report in early 20th century. The current report will augment our understanding of the floristic relationships among SE Asian countries and will help elucidate the biodiversity of Lao PDR.
