This study was conducted to obtain information relevant to resolving problems related to artificially introduced plants in ecological restoration projects. We investigated artificially introduced plants and plants growing naturally from its surroundings in the active restoration sites of the Ecosystem Conservation Fund Return Project (ECFRP) of the Ministry of Environment and the Civilian Control Zone Forest Restoration Project (CCZFRP) of the Korea Forest Service. We also analyzed the characteristics of native, exotic, and cultivated plants in addition to their Raunkiaer's life forms. Furthermore, we compared the planted areas and inhabited areas, as well as the characteristics of the habitats of native plants among the planted plants. We found that among the plants planted in the ECFRP, 50.4% were native, 6.8% were exotic, and 42.9% were cultivated. Meanwhile, in the CCZFRP, 78.6% were native, 21.4% were exotic. We also noted that many native plants were found in the planted areas that were far from their habitats. In addition, we identified many native plants that were planted in areas judged to have characteristics different from that of their natural habitat. In the case of Raunkiaer's life forms, the planted plants showed high ratios of megaphanerophytes (MM) and microphanerophytes (N), while the invasive plants showed high ratios of therophytes (Th) and hemicryptophytes (H). When restoring the ecosystem, the ratio of planting native plants should be higher than that of exotic or cultivated plants. Moreover, the habitats and ecological characteristics should be considered when selecting native plants to enhance the effect of ecological restoration.

The purpose of this study is to examine the present problems relating to the legislation and execution of adornment of buildings in the provinces, and to explore ways to improve the role and function of adornment of buildings in terms of public art. In order to do that, the related national law and enforcement decree and the local regulations and rules were analysed. In addition the catalogues on the adornments of buildings that are managed by 31 cities and counties of Gyeonggi-Province were also compared and analysed. As a result of our survey, it has been determined that the reform of the adornments of buildings must be executed on the national and local levels. On the local level, the revision of regulations must occur simultaneously with the changes of national law and enforcement decrees. In many local self-governing bodies, there are quite a lot of discrepancies between their regulations and the upper law. Therefore, people can be confused regarding the sensitive problems such as the types of buildings that are required to display adornments and the proportion of the cost to the construction cost. In addition the effects of the improvements to national laws are often delayed. For example, the updated national law requires committee members to be appointed on the basis of merit, the announcement of the deliberation results, and the establishment of provisions regarding the management of existing structures. Unfortunately, improvements to the national law are not followed through on a local level. Concerning national legislation, the following improvements are necessary to minimize these problems. First, the western concept of‘public art’must be imported to Korea and applied to future legislation regarding adornment of buildings. Second, the perception of the purpose of adornment of buildings must be changed from‘art promotion’to‘improvement of the urban environment’Third, it is impractical to require private citizens to fund public worts of In. Korea requires an organized federal funding system for the commission of public art, which is to be controlled by committee. Finally, the definition of public artwork must be enlarged to include a more broad range of art, such as landscape architecture. In addition, continuing care of existing public worts of art must be managed systematically and strengthened.

The Ecosystem Conservation Levy (formerly known as the Ecosystem Conservation Cooperation Fund) system has been in place for 20 years, and it can be said that it has now entered the settlement stage. Based on an analysis of publicly available project implementation data from 2014 to 2020, we found that: 1) As the number of return projects increases, the targets of restoration technologies are also strengthening, and it is necessary to frame a series of processes from application, creation, and monitoring for some detailed projects to improve the effectiveness and efficiency of utilizing the levy. 2) Most of the implemented projects are applied as micro-ecosystem creation, but there are many cases where the contents of the project can be seen as other project categories. This shows that the purpose of the return project needs to be approached more clearly and suggests that institutional complementation is needed from the project application stage. 3) The detailed technologies applied tend to be gradually expanding, but most of them are technologies that are not differentiated from general development projects. It is urgent to secure a more technical identity, such as a range and list of utilized technologies suitable for the characteristics and purposes of return projects. 4) It is necessary to establish a relevant evaluation system or framework to utilize the monitoring results of restoration projects. 5) There have been few cases of application of single restoration technologies since the beginning, but the content and scope of the complexity tend to expand in recent years. Even if the objectives are not comprehensive and diverse, it can be seen that many parts of the projects are oriented toward convergence, so it is necessary to conduct separate research on this. 6) As for the direction of improvement of the return project, it is possible to consider expanding the restoration and conservation focus to partially accommodate the complexity of the natural environment and human ecology. It seems that the expansion of restoration technologies that consider the role and function of humans in the natural environment should be explored.

In addition to the measurement of the concentration of soil contaminants, the new idea of indicative parameters was proposed to validate the remedial works through the monitoring for the changes of soil characteristics after applying the clean up technologies. The parameters like CFU (colony forming unit), pH and soil texture were recommended as indicative parameters for land farming. In case of soil washing, water content and the particle size distribution of the sludge were recommended as indicative parameters. The sludge is produced through the particle separation process in soil washing and it is usually treated as a waste. The parameters like water content, organic matter content, CEC (cation exchange capacity) and CFU were recommended as indicative parameters for the low temperature thermal desorption method. Besides the indicative parameter, sampling methods in stock pile and the optimal minimum amount of composite soil sample were proposed. The rates of sampling error in regular grid, zigzag, four bearing, random grid methods were 17.3%, 17.6%, 17.2% and 16.5% respectively. The random grid method showed the minimum sampling error among the 4 kinds of sampling methods although the differences in sampling errors were very little. Therefore the random grid method was recommended as an appropriate sampling method in stock pile. It was not possible to propose a value of optimal minimum amount of composite soil sample based on the real analytical data due to the dynamic variation of $CV_{fund{\cdot}error}$. Instead of this, 355 g of soil was recommended for the optimal minimum amount of composite soil sample under the assumption of ISO 10381-8.

As the Construction Technology Promotion Act was revised in 2015, the term of Supervision was removed and Construction Management was included instead. The consideration of Construction Management shall be based on the cost plus fee method specified in the Criteria for the Cost of Construction Technology Services of the Ministry of Land, Infrastructure and Transport. Nevertheless, it is based on the construction cost ratio in accordance with the Economy and Finance Ministry's Detailed Guidelines for Preparing the 2018 Budget Plan and Fund Management Plan (Manual for Business Type and Item). As a result, it has been expected that Construction Management consideration will be calculated according to a single government standard and that the Criteria will be applied reasonably. In addition, although the change in the Labor Standard Act has a significant effect on the working environment of the construction site, the nature of the construction site is not considered in this Act. Based on these problems, the study suggested that the government should apply a single standard after consultation with the relevant agencies when calculating the consideration for Construction management, that the scope of the Criteria for the Cost of Construction Technology Services should be clear, that the amount of input by the Construction Manager should be considered for the capability of engineers and the number of working days, and that construction characteristics should be considered when determining the number of working days and hours.

The purpose of this study was to investigate the sanitation affairs of general restaurants. The questionnaire survey on the attitude and knowledge toward sanitation, the attitude for sanitary administration and the sanitary education was conducted against new 600 restaurateurs who were educated from June 20 to July 11, 1996, at the administration hall's division of Kyungsangbook-do in charge of food industry that offered regular sanitary education to new restaurateurs annually. And the visit survey on sanitary practice was also conducted over 93 restaurateurs who obtained the commercial license for food service business. The findings from the survey were as follows; In regard to food sanitation, some 87.1 to 88.3% got the right knowledge about the reason and precaution of food poisoning, food's frozen or cold-storage, and the disposal of products after expiration of validity term. But it was about 20.8% to 50.0% who knew right about major precaution, storage temperature in refrigerator, fermented milk product's storage temperature and validity term. There was therefore a necessity for education in food sanitation. 38.2% of the subjects placed an emphasis on sanitary storage of foodstuffs as the most important thing in sanitary management. 33.8% emphasized cooking sanitation. The environmental sanitation was counted as the most important thing by 19.2%, and personal sanitation of worker was counted by 8.8%. There was differences in what they thought the most important thing was, according to the respondent's educational level and cooker. 86.6% replied it necessary to improve the sanitary level. The respondents who were younger or had better educational level emphasized more the need for it. Concerning health examination, 90.2% replied it necessary. 81.4% answered the reason was because there was a potentiality Quests might be infected with contagious disease. 78.5% pointed the need for sanitary education, but respondents with higher educational level less emphasized its needs. As the reason for poor sanitation, restaurateur's poor awareness about it was most frequently pointed out, by 46.9%. Cooking sanitation was most frequently counted, by 38.5%, as the first thing to be improved. As the most critical point in sanitary education, 34.5% indicated food's sanitary Quality control 30.9% mentioned sanitary treatment of kitchen facilities and peripheral environment, and 27.1% emphasized the summary of the general food sanitation. 77.7% answered to correct immediately in case of violating the Food Hygiene Law, and 12.0% replied to correct in the same case if they would get the order from public official or administrative action would be taken. Respondents with higher educational level answered more to correct immediately. What they wanted the government office to do toward sanitary improvement was a fund aid an facilities and management which was pointed out by 38.9%, a periodical sanitary education by 26.3% and a on-the-spot guidance of sanitary officials by 22.3%. In view of the food service business's sanitary practice, the rate of wearing a sanitary clothes was 32.9% in city and 35.0% in county. The rate of hand-washing without soap or non-washing at cooking was 73.9%, 85%, respectively. The rate of personnel sanitation was 34.2% in city and 50.0% in county. These things indicated the sanitation was not well practiced. To improve the poor sanitary conditions of the food service businesses, it is recommended to offer institutional backing and financial aid from administrative office, and encourage restaurateurs to take pride in their job. and conduct the sanitary education effectively by sanitary education institution.
