This study was carried out to investigate the relationship between visitor uses of national parks and economic variables, such as the index of industrial product and the consumer price index. The results from the Granger Causality test showed that the index of industrial product and the consumer price index influenced visitor use at national parks. Also the Impulse Response Analysis showed that the index of industrial product and the consumer price index greatly influenced national park visitor use in the short term as well as the long term. The study showed that national park visitor use was mainly influenced by variance decompositions. These results suggested that economic variables could be used to not only forecast the demand for recreation but also establish recreational policies.

Comprehensive development projects were carried out on the Han River from 1982 to 1986 for the purpose of creating a more serviceable places such as a riverside parks and autoroads and so on. However because of the river development, river ecosystem and function were destroyed. And many local autonomous entity follows comprehensive development projects as if it is a model case. To investigate the impact that the river development effects the river ecosystem, two sites which are Anyangcheon and Sooipcheon were surveyed in the right of around plants ecosystem and structure. Two sites are creek of the Hna River. Sooipcheon maintains the sound ecosystem. It has sufficient carrying capacity for the river recreation activity. The reason is that a hydrophyte absorbs nutrients from the stream and the river ecosystem meets the around terrestrial one neturally. Number of hydrophyte increase from upstream going forward to downstream. Number of hydrophyte increase from upstream going forward to downstream. Anyangchoen is seriously polluted stream out of many branch stream of the Han river. In the upstream various woody plants and hydrophyte appeared. But from the river developed area at midstream, naturalized plants dominated such as Bidens tripartita, panicum dichotomiflorum etc. To manage the creek ecologically, hydrophyts were introduced in partly for natural purification after rehavilitate the riverside, and steadily monitoring is demanded.

Urban parks and open spaces provide the community residents with the most easily accessible source for outdoor recreation, contributing also to the improvement of quality of natural environment in urban area. The demands of urban residents' for more and better green area are ever-increasing. However, the level of most urban open spaces which are easily accessible for residents are not satisfactory to meet the residents' demand in availability and in quality as well. Most existing urban open spaces are simply built of green areas only or have been developed in almost identical design with little consideration for individual uniqueness of the site. When developing neighbourhood parks in urban housing complexes, for example, little consideration is being given to topographical conditions, interrelation with the adjacent green area, or viability of the urban ecosystem. In many cases, urban park development projects are being done with serious negligence of natural properties of the site, by even destroying existing healthy woodlands. for instance. The objectives of this study are; -To survey on the domestic and the overseas cases of regulatory systems, development status and planning methods for urban open space. -To identify underlying issues of residental park developments in urban housing projects and establish appropriate improvement measures thereof, by studing and analyzing current-use data of developed urban parks and management status thereof. -To establish improved standards for urban open space planning, by integrating above surveys and studies, and recommendation for revision of related legislation is also presented to implement these standards.

Methods for determining the instream flow in the stream were explored and examined through careful reviews and evaluations of available literatures. Development of the instream flow estimation method is based on the reviewed results and methods which can be used within the acceptable levels.The newly-developed method was tested on the streams which require maintaining some riverine functions, such as the instream flow and river-management flow at the specific channel reach or representative station of the river. The riverine functions mainly considered in this study are the minimum flow, water quality conservation, fish habitat rehabilitation and conservation, riverine aesthetics, river navigation and recreation, and so on. As a result, the newly-developed instream flow estimation method is expected to be used effectively for determining the instream flow, which is necessary in order to maintain the natural or artificial riverine functions.

Background Human bite wounds in emergency department need evaluation in regard of reconstruction. These are due to occlusive bite injuries over face. Most commonly, human bites over face involve ear and nose, and may lead to avulsion injury. Defects over nose can be reconstructed immediately after debridement or delayed till the wound heals and scar becomes supple. Thorough wash and lavage with broadspectrum antibiotic cover has utmost importance in preventing cartilage infection. Methods We report 20 cases of human bite injuries over nose who presented to us in emergency department between 2018 and 2020. At the time of presentation the wound was assessed for closure. If not possible, patient was planned for delayed reconstruction after 3 months. In case delayed reconstruction was planned, the skin and nasal mucosa were approximated at first presentation. The patients underwent paramedian forehead flap after recreation of defect with conchal cartilage graft. Second stage of flap detachment and insetting was done after 3 weeks. After three weeks of second stage, third stage of flap thinning was done. Patients were followed for 3-6 months and subjective satisfaction was noted. Results Nineteen patients underwent delayed staged reconstruction with paramedian forehead flap and one underwent primary wound closure. The flap survival was 100%. The patient satisfaction was excellent in most cases. Conclusion We recommend delayed reconstruction for human bite nasal injuries. For reconstruction, paramedian forehead flap with conchal cartilage graft, if required, provides excellent reconstructive option with good contour and color match and minimal donor site scar.

The purpose of this study is to establish more rational and practical planning theory for amusement park. It analyze and consider the fluctuation of people who come and use the Tong-Ch'on amusement park. The results drawn from this reserch work are as follows; 1. The main visitors of the Tong-Ch'on amusement park are students in their twenties and thirties, and people whose incomes are below 300,000 Won a month. The purpose of visit is for a rest rather than for amusement and user prefer summer, while the user is so rare in wintertime. Those phenomena observed are somewhat different from the real purpose of a amusement park which is on purpose to make profits by offering entertainments to the users. So planner should pay attention to the three points. They are varieties, seasonable diversification and fantastic character of facilties, in the amusement park. 2. The access time of the Tong-Ch'on amusement park was 41 minutes, the use frequency was 4 times a year and resident time was 164 minutes. The relationship of the three factors are as follows; log Y(F) =1.7832-0.0277(A.T) R$^2$=0.75 Y(R. F)=31.8885+3.3217(A.T) R$^2$=0.53 Y(R. T)=224.8959-87.8309 1og(F) R$^2$=0.38 F;Use frequency(time/year) A.T;Access Time(minute) R.T;Resident Time(minute) 3. In the choice of space, there were much differences according to tole user's age, job, degree of education, companion type and purpose of use. 4. There are considerable correlation between use fluctuation and some factors. The factors are season(summer, winter) as a time, temperature, cloud amount, duration of sunshine, weather(rainy-day) as a climate and a day of the week(weekday, holiday) as a social system. The important variables are temperature, cloud amount, duration of sunshine and a day of the week(weekday, holiday) to estimate the user of amusementpark. 5. 1 can reduce the following two types of regression models. 1) log$\sub$e/ Y1 = 6.9114 + 0.l135 TEM + 0.00002 SUN -0.4068W1 + 0.4316 W3 (R$^2$= 0.94) 2) log$\sub$e/ Y2 = 7.2069 + 0.l177 TEM - 0.0990 CLO + 0.4880 W3 (R$^2$=0.95) Y; Number of User TEM; Temperature CLO; Amount of cloud SUN; Duration of Sunshine W1; Weekday W3; Holiday Those model is in order to estimate the user for management of Tong-Ch'on amusement park and use on the computation of facility sloe for reconstruction. Besides the amusement park, city park and outdoor recreation area could estimate of user through this method. But, I am not sure about the regression models because I did not apply the regression models to the other amusement park, city Park or outdoor recreation area. Therefore, I think that this problem needs to be studied on in the future.

This study was conducted to find out whether persuasive messages with different contents of information (aesthetic, aesthetic+ecological, aesthetic+ecological+economic, aesthetic+ecological+economic +educational) about the consequences of littering influence users' awareness of the consequences of littering, personal norms and littering behaviors in a recreation setting based on the Schwartz's norm activation theory. Data were collected at the Second Campground in the northern managerial district of Chirisan National Park. Of the total 177 questionnaires distributed, 144(85%) were used for the study. In addition to that, in order to find out whether personal norms on littering were changed from 1994 to 1996, data collected at the same campground in 1994 were also partly used. Based on the result of the study, persuasive messages didn't directly affect the users' level of the awareness of the consequences(AC) of littering, personal norms, and littering behavior. People whose awareness of the consequences of littering are higher, however, tended to have stronger personal norms about littering. And also, people whose awareness of the consequences of littering are higher or people whose personal norms are stronger appeared to litter fewer than people whose awareness of the consequences or the strength of personal norms are lower. The extent of personal norms about littering was not changed through 1994 to 1996. The results were discussed and some management alternatives were suggested.

The full grasp of recreation demand and factors affecting on recreation demand can be very important information for park planning and management. The object-tives of this study are to investigate factors affecting the fluctuation of urban park visitors and to analyze the relationship between these factors and the daily parti-cipations. The results were as follows; 1) The peak of monthly participations comes on May, April, August and October in order. And these months are specified as school picnic period and vacation of school children. 2) In correlation analysis, the variables such as ‘Day of a week(D)’, ‘Monthly mean temp.(T)’and ‘Monthly character(M)’have high correlations with ‘No. of visitors’in order. And it is better to categorize months by its charater(picnic period in school, vacation etc) than by seasons. 3) Candidate regression model were established, as for 1984 log U= 1.51 + 0.64D1 + 0.02T + 0.36W1 - 0.23M4 + 0.003SS + 0.24Ml($R^2$=0.5326) where, U=no. of daily visitors D1 = sunday.ho1iday(1), weekday(0) T=monthly mean temperature($^{\circ}C$) W1= weather (sunny.cloudy(1) , rainy (>5mm)(0)> M4=non vacations and non school picnic period(1) , if not (0) SS=monthly sunshining hours M1=summer vacation(1), if not(0) 4) The most important variable was ‘Day of a week’(sunday.holiday or not). And temperature, weather and monthly charcter(especially picnic period of school and vacation) were in turn, hence ‘Children's grand park’shows the use pattern of park.

During the COVID-19 pandemic, social distancing affected daily life and leisure activities, including forest recreational activities. This study identified changes in people's participation in forest recreational activities and factors affecting their participation. It collected data from 1,000 samples through an online survey and analyzed it using a binary logit model with interaction terms. It was observed that there were decreases in the participation in visits to urban parks and green areas, outdoor activities in forests and mountains, and trips to mountain villages after the COVID-19 outbreak. People in their 40s, 50s, and 60s were more likely to decrease their participation in all kinds of forest recreational activities than those in their 20s. Moreover, higher household income earners were more likely to decrease their involvement in outdoor activities in forests and mountains. With respect to the place of residence, the residents in the Seoul metropolitan area were less likely to decrease their participation in trips to mountain villages than those outside this area. Thus, this study suggests that online forest recreation information services and forest management are needed to meet the demands of forest recreation for young generations and diversify the function of forests and rural areas as a safe leisurely space.

The purpose of this study is to analyze college students' perception of national natural heritages, including natural monumentsand scenic sites, in comparison with the similar concepts of national parks and eco-landscape preservation areas, to suggest managerial implications to enhance competitiveness. The first objective of this study is to measure their attitude toward traveling each type of natural heritage and to rate the relative importance of the four types of heritages in terms of preservation. Natural monuments were perceived as the most strongly preserved type, while scenic sites were perceived as the least strongly preserved type. The second objective is to conduct a correspondence analysis to match the concepts of four types of natural heritages with 10 tourist attractions representing the types. It was found that college students have difficulty appropriately identifying the types of 10 tourist attractions. In addition, multi-dimensional scaling (MDS) was implemented to identify the similarities and differences of the four types of natural heritages and to produce a positioning map matching the four types of natural heritages with the six attributes representing each type as a tourist attraction. Natural monuments were perceived very differently from scenic sites and not very differently from eco-landscape preservation areas. There were a few associations between the four types of natural heritages and the six tourism attributes, implying that little effort is made to promote and position each type of natural heritage in terms of tourism. In conclusion, a public awareness program is required to enhance the brand image of natural monuments and scenic sites in comparison to national parks and eco-landscape preservation areas. In addition, local residents who live near the natural heritages should be bolstered to play a managerial role as supporters and contents providers for sustainability.
