This study aims to analyze the current status of timber production operation and the effects of the forestry mechanization projects on timber production. In order to increase the domestic timber production, it is necessary to propel forestry mechanization project, improve policy and institution, broaden forest-road network, enlarge the number of forest workers, enhance timber production and supply system, provide forestry machines, establish forest operation system, and train forest workers. In addition, the reestablishment of policy goals, the consistency of policy, and the rearrangement of laws and institution are considered more important. To improve the results and effects of forestry mechanization project, it is necessary to drive of forestry mechanization project, the spread of forestry machines, the cultivation of trainer ability, the development of training materials, and the teaching of field skill. In order to meet timber buyersí preference, timber needs to be produced through whole tree logging operation system. Expanding the proportion of domestic timber among total timber demand in Korea requires price competitiveness, and the supply ability of high quality product from the perspective of length and width.

The purpose of this study is to investigate the current status, including the maintenance problems and removal efficiency, of small sewage treatment facilities in Chung-nam province(Asan, Buyeo, and Gongju city). Our results showed that inflow water quality of Asan city was 19.1 mg/L of BOD, 29.0 mg/L of COD, 13.4 mg/L of T-N and 1.5 mg/L of T-P, respectively, which was much higher than any other site. Among the factors known to be an important index of water quality, the SS and BOD removal efficiency was about 70% and 50% respectively. However, the nitrogen removal efficiency was less than 10%. The total removal efficiency of pollutant was 71.1% of SS, 52.6% of BOD, 46.2% of COD, 9.2% of T-P and 4.6% of T-N respectively. Therefore nitrogen removal processes are required to prevent serious eutrophication of small river. Removal efficiency for BOD and SS of high-efficient sewage treatment facilities (STFs) and contact oxidation process was much higher than another process. Performance of these sewage treatment facilities(STFs) is not optimal due to ineffective planning for the inflow water quality. To improve these facilities, it is proposed that a technical expert analysis of water quality at these facilities is periodically required.

Fintech, a new form of financial industry that converges IT, is developing rapidly in developed countries such as the US and China. The U.S. and China lowered barriers to entry through deregulation to develop and expand the fintech industry, and, for example, encouraged startup companies to incorporate various ideas through negative regulations that are more relaxed or do not apply regulations for a certain period of time. The U.S. and China did not apply existing financial regulations to the fintech industry, providing an environment where fintech startups could grow more easily. Currently, in Korea, fintech technologies such as 'Samsung Pay', 'Toss' and 'Kakao Pay' have been developed and are being activated, and also their scale is expanding. Although various systems are being reorganized and regulated for the development of Fintech, Fintech's growth rate is slow due to unfriendly and unopened regulations in the financial sector and various markets. This paper examines the status of fintech, focusing on advanced fintech and Korea, and examines fintech-related regulations that hinder the development of the fintech industry. We propose a more flexible way of easing excessive regulation in the financial sector, such as post-regulation.

This research analyzed the status and problems of civilian expert programs for landscape architects to suggest alternatives to improve the current system. Literature research focused on the issues of the legal definition of civilian experts, the background of the program, and related regulations. Based on the understanding of the legal system, the research analyzed the operation status, structure, roles of the civilian expert program of local governments where landscape architects were delegated as civilian experts. Currently, 50 local governments are running the civilian expert program, and landscape architects are working as civilian experts in 11 institutions. The majority of landscape architects are working as MA or general architects. Only SMG runs an independent general landscape architect program. Based on the literature research and interviews with 16 experts, the research examined four main issues related to the program. First, the legal system issues of the civilian expert programs are related to the regulations assuming architects as experts. Revising the current legal system is a better alternative than promulgating a new law for landscape architects. Second, the compensation issue was a main problem related to operation. Securing a sufficient budget and more effective administration is required to solve the problem. Third, related to the role, the tasks being limited to consultation were regarded as the main problem. Although landscape architects wanted more opportunities to directly participate in the project's design, the fairness of the public project contracting system needed to be considered. Fourth, the competence issue is related to the number of available landscape architects. This issue can be solved by expanding the pool of civilian experts to adjacent disciplines, such as public design or landscape management.

The influence of land use and pollutant source on water quality was investigated using 3-yrs monitoring data major influent stream in Hwaong reservoir watershed. The seven water quality station (N1, N2, J1, J3, J4, E2, E3) were used analysis of land use and pollutant effect, and six water quality station (N3, N4, J2, J5, E1, E4) were used analysis of waster quality status. Water quality parameter were positively correlated with residential and forest, negatively with paddy and upland especially during dry period. During wet period, correlation between land use and water quality was less apparent. Population and livestock density was correlated well to water quality parameter than just number of population and livestock. The watersheds studied are mainly non-urban and their land uses are similar to typical watershed of other estuarine reservoirs, therefore, the correlation developed in this study might be helpful to manage other estuarine reservoir watersheds.

This research has conducted historical data analysis and on-site investigation on Chungam Pavilion and Seokchun Valley in Bonghwa. Based on the results, the original planting form was identified, and the vegetation management were drawn up. The results of this study can be summarized as follows. First of all, The Book of Seokchun states that there used to be forest trees such as pine tree, saw-leaf zelkova and maple tree, and flowering trees such as peony, royal azalea, rose, chrysanthemum, and lotus, planted around Chungamjeong. Around Seokchunjeongsa, there used to be boxwood, bamboo, maple, peach, gooseberry and peony planted in the area. Through this discovery it can be realized that the vicinity of Chungam Pavilion and Seokchunjeongsa provided not only the grand aesthetics of four clear seasons, but also planting landscapes with various symbolistic significance and meanings. The description of the planting situation in the historical records offers a useful reference for future vegetation management in Chungam Pavilion, Seokchunjeongsa and surrounding valleys. Furthermore, it holds critical value in the identification of planting pattern in late Chosun dynasty. Second, the planting landscape in and around Chungam Pavilion and Seokchunjeongsa will have to be maintained as described in the historical records The Book of Seokchun. Also, the once famous colony of pine trees in the area is gradually reducing in its scale, which calls for active management measures such as elimination of broadleaf trees.

It is usually proposed that job security of old age workers is hampered by the structure of wage increasing with age. This paper sets forth a model to comprehend the characteristic of the old age workers' labor market and policy implications derived from it. In order to stimulate demand for old age workers, policy initiatives should be taken as follows : the wage criteria should be simplified which apply differently from one institution to other; incentives relatively favorable for employing old age workers' in manufacturing sector should be also given to service sectors; employment subsidy or other tax incentives should be given for labor contract after the retirement age; licensing and evaluation system for job ability should be introduced based on occupation & job analysis. To lower the reservation wage of workers, mortgage loan for house and long-term low interest loan for tuition fees should be developed together with stabilization of housing cost. Wedding culture which requires high expense should be amended. Above all, it is necessary to install reasonable social security system. Policy orientation should also pay attention to reduce labor supply of the old aged via aiding old age workers' firm opening and voluntary civil service together with developing various honor programs for members of civil corps.

Real-time oceanographic information system was developed using platforms of aquaculture farms to examine causes of mass mortality of hatchery fishes, and to reduce the damage of mass mortality which has been occurred frequently off coast by abnormal change of ocean conditions. The system had the advantages of direct data distribution to fishermen at the farm and instant maintenance of equipments due to easy access to the farms and residents at the farms in comparison with offshore mooring buoy system. To avoid discontinued measurement of the system, repairs caused by malfunction of equipments, bimonthly preventive maintenances and daily monitoring of measured data were systematized. Confidence intervals calculated by a statistical method using accumulated data were applied to data management. Such activities could minimize discontinuance of measurement and keep information more trustful. In addition, the system has various ways of data distribution. Through homepage and e-mail in the internet, information was provided to public. Display units which were connected to equipments at the farm gave the measured data directly to fishermen, which guided them to run their farm scientifically. Finally large display unit was installed at a fish market and showed the measured data at the nearest station with tide and weather information. Proper region for aquaculture and wintering region were studied using temperature data obtained by the system in 2006. The system will contribute to reduce economic damage of coastal fishery and to understand coastal marine environment.
