Generating rate of food waste in Korea is relatively high as 11,793ton/day corresponding 26.5% of municipal solid waste(USA 25%, England 19% and Germany 28%). Food waste is now separated from other solid wastes by solid waste management law and efforts of NGO. Thus, there is a need to develop effective and efficient technologies of food waste treatment. In this study, vermicomposting was applied to food waste mixed with sludges from a pulp and paper industry. Lumbricus rubellus grew and reproduced favorably in mixtures of organic sludge containing up to 70% of food waste. The casting was rich in nitrogen and phosphorus with 19.9 ~ 20.6 of C/N ratio.

營利經營面에서 본 私有林營林計劃의 實踐性에 대한 硏究

權雷澤,李相植 東國大學校 1967 論文集 Vol.3-4 No.-

1. According to the 8th article of forest law, a owner of forest land of 100 chong-bo or more should prepare by himself a forest management plan as a specific working section and get the approval of is from the concerned local governor to manage an enterprise on the forest. The government forest policy of requiring each specific working section to prepare it's working plan within 3years between 1965-1967 and enforce it is an epoch-making one for cultivating the forest recources, promoting the land productivity and enterprising the forestry. 2. Among the private forests, the professional and reasonable working plan of the specific section plays a vital role, and its achievement would become the barometer for successfully leading the management of other general private forest 3. The collision of the permanent benefit of the public and private interest could be seen most often in the forest management. Encouraging the forest enterprise of the specific working sections of private forests fits to the public benefit and the better national economy, Therefore positive assistance with finance and technology should be provided for them. 4, Cho-Kye san specific working section. location: Sung Joo Gun, Chun-Nam. area: 300. 00chung-bo. owner: Dongguk university foundation. The forest stock in this section have been completely devasted by illegal and uneconomic cuttings, and it's devastation represents many other private forest as we see. Ultimately it's forest working plan consists of only planting plan, in other word, without cutting plan. For the first management period, we can't expect production of woods and must only invest for silviculture. For enforcing the working plan of such forest land, a consideration must be given for the following matters. a) The forest enterprise is a long range project for return, compared to other product enterprises, the forest enterprises produces a law profit. Most of forest land owners are financially poor, so capital investment can't be expected to them. Especially for a proprietor for poor capital, his courage is likely to be killed by the prospect of poor economic loan, and the high interest of loan and so forth. Therefore, a government loan of low interest is urgently needed. b) For the first management period where no production of woods and timbers can be expected and the investment silviculture only require, a financial subsidy policy is needed to enable the preparation and enforcement of the working plan. c) Present principle of organizing the forest working plan fits to the production of wood and timber only thus, a long rage investment is invitable. A Multiple forest working plan of long rage, middle rage and short rangemust be born, combining forestry, agriculture, and pasturage. d) For those forest lands which had been bought or rent with the actual purpose, of managing an enterprise, a special measure of diminishing the financial burden, such as, tax, and registration fee from the preparation of forest working plan should be provided. 5. Un-Mun San specific working section. location: chungdo gun, Kyung-puk. area: 570.40 chung-bo. owner: Dong guk university foundation. This section has the most prospective conditions for the forest management. It's site is good, and it has he forest volume stock approximately 64 cubic meters(㎥)per chung bo. It is one of the bests among the private forest through the country. To develop such prospective working section, a consideration must be given to the following situations. a) Present principle of preparation of working plan regulates to adapt the allotment method for continnal volume yield, and thus, an unreasonable financial sacrifice is inevitable and the properietor is not allowed the using of his own ideas. The insect, desease and forest fire or over-grown trees should be cut immediatelly, and the incomes from them should be invested for the establishing of second growth. A system of inspection over the resources building with such special forest budget system is more needed than the cutting control under inspection only for the purpose of continual volume yield, b) The system of designating the use of produced log should be conducted in accordance with the quality of log, and so an unreasonable financial sacrifice on the part of propretor should be aboided. c) The specific working section should be managed by the professional forest propretor engaging in the whole forest production process.―such as, nursery practice, establishing, developing, protecting and logging. The government subsidy for seedling should be used for the direct benefit of such professional proprietor, and the system of mechanically allocating the seedlings should be avoided. 6. The Dongguk University foundation owns several specific forest working sections over the country. For such big owner, the government should directly control and guide them so that the management could be conducted harmoniously with a creative approach.

골분진과 섬유소 접합물을 이용한 두안면부 골결손의 치료

권성택,박양수,김진환 대한성형외과학회 1992 Archives of Plastic Surgery Vol.19 No.3

In the field of plastic surgery, various forms of craniofacial bone defects may be encountered under such conditions as trauma, congenieal defect, and postoperative condition. Until now, autogenous bone graft, processed homograft or heterograft, and alloplastic implants have been used for the reconstruction of those defecrs. Although each method has its own pros and cons, autogenous bone graft is most widely used because of its high survival rate, low postoperative complication rate, and longterm stability, Recently, the calvarium has become the favorite source of autogenous bone graft since it has many advantages. However, it is not easy to fabricate bone graft to fit in the defect accurately, paricularly for cystic or irregularly shaped depressions of craniofacial bone defects. In 1970, Shehadi reported the use of calvarial bone dust in reconstruction of cranial defects. Bone dust is harvested easily and in reasonably sufficient amount, but has not been used widely due to problems in fixation and survival rate. In our previous study, authors experimentally proved that a miture of fibrin sealant and autogenous bone dust plays an effective role to form a new bone in bone healing process. Fibrin controls bleeding, serves as a surface for adherence and degranulation of platelets, and accelerates would healing in general. In the healing process of bone grafting, fibrin trellis is known to contribute to osteoconduction and osteoinduction by supplying moving channels for undifferentiated mesechymal cells and bone morphogenic protein. Clinically, authors successfully treated 7 cases of craniofacial bony defects using bone dust and fibrin sealant and concluded as follows ; 1. Bone dust is easy to harvest in sufficient amount and is useful in reconstruction of various forms of bony defects. 2. Bone dust can be easily fixed when mixed with fibrin sealant. 3. Fibrin sealant stimulates bone union of bone dust graft. 4. Bone dust can also be harvested simultaneously when harvesting calvarial bone graft and be used in various craniofacial reconstruction as mixture with fibrin sealant.

탈석회화골분진과 폴리에틸렌을 이용한 대용골에 관한 실험적연구

권성택,이윤호,김진환 大韓成形外科學會 1993 Archives of Plastic Surgery Vol.20 No.6

Advances in craniofacial surgery have stimulated the interest in physiology of osseous transplantation. Numerous works have been made to understand physiology of bone graft. In the bone graft, many researches have been focused to solve the following problems; First, the shortage of donor site. Second, variable degree of resorption. Third, limitation of shaping of bone graft. This study was undertaken to evaluate the morphogenic properties of bone substitute and its fate after 6 months of implantation to the back of experimental animal. Bone substitutes were prepared by filling of demineralized bone power to the inner space of porous polyethylene block. Size of the porous polyethylene block was 10 ×10 ×7mm and that of inner space was 7 × 7 × 4mm. Experimental group consisted of implantation of bone substitute into the musculatoure of back of adult New Zealand White rabbits. Control groups were divided into 2 groups : namely group 2 which has inner space of porous polyethylene block without demineralized bone powder and group 3 which has neither innerspace nor demineralized bone powder but only porous polyethylene block. Rib bone between each implant was considered as an another group (group 4) for a reference of isotope uptake. ????Tc-MDP uptake and histomarphometric evaluation with light microscope showed induced osteogenesis of demineralized bone powder within the inside of porous polyethylene. At 1 month after implantation, composites didn't make significant difference from control groups. From 2 months to 6 months, radioisotope uptake increased with sharp curve(1.69 at 2 months, 3.35 at 4 monts and 4.53 at 6 months) and number of osteocytes, osteoblasts, chondrocytes and chondroblast also increased with steep line(3.3 at Zmonths, 27.6 at 4months, 95.4 at 6 months), while control groups could not show any evidences of induced osteogenesis and better incorporartion. The results of this study suggested that creation of osteogenic composites of porous materials and osteoinductive bone powder can be one of the rational approach to solve the problems of bone graft.

Fibrin Scalant 를 사용한 골자가이식에서 혈관신생에 관한 실험적 연구

권성택,김병건,김진환 大韓成形外科學會 1993 Archives of Plastic Surgery Vol.20 No.3

The effect of fibrin to wound healing has been studied and well documented : homostatic and adhesive effect and stimulatory effect on proliferation of fibroblast, formation of granulation tissue and neovascularization has been well known. In the process of bone healing, action of fibrin has been reported to stimulate the formation of granulation tissue, new vessels and new bone, but there have been many reports contrary to the effects of fibrin. Authors used New Zealand white rabbit as an experimental animal. Bone grafts were harvested from right and left parietal bone and onlay grafts were performed to both sides of frontal bone. Fibrin sealant was applied to experimental group and was not applied on the control group. Both groups were sacrificed after 1, 2, 3, 4, and 8 weeks respectively and results were examined and compared after H&E stain and Masson's trichrome stain by light microscope. The group using fibrin sealant showed new bone formation on 1st week and new vessel formation on 2nd week, and vessels were numerous and had thick walls. And there were dense bony connections between donor bone and recipient bone. In calvarial bone graft which is most commonly used in plastic and reconstructive surgery, especially in infected and extensively injured wound which might compromise blood supply, we believe that bone graft using fibrin sealant can stimulate vascularization and new bone formation and therefore enhance the survival of bone graft.

The purpose of this study is to determine whether movement strategies affect functional forward reach distance in a standing position. Forty-seven healthy subjects were selected for this study: 23 men and 24 women, with an average age of 22.3. Functional forward reach distances were measured as hip strategy and squat strategy(included knee and ankle movement strategy) in a standing position, respectively. The mean values of functional forward reach distance in hip strategy, squat strategy were 33.57㎝, 29.48㎝, respectively. There was significantly difference in functional forward reach distance between hip strategy and squat strategy(p<.001). There was no difference of functional forward reach distance between male and female in hip strategy, but there was significant difference in other strategy(p<.05). These results suggest that movement strategies should be considered during functional forward reach test in standing. Further study is required to determine whether movement strategies affect functional reach distance in elderly and disabled groups.

The Milyang River in one of the tributaries which affects the water qualify of the Nakdong river. The STREAM(Segment Travel River Ecosystem Autograph Model) was applied to estimate the purification capacity of the Milyang river. The entire study area(23 ㎞) was divided into 13 reachs. Each reach was then subdivided into uniform reaction cell of 0.1 ㎞. Field data were obtained from two field sampling surveys during Summer(Agust, 1993) and Fall (November, 1993) periods. The model was calibrated by the August survey data and verified by the Fall survey data. The computed values by the model were in good agreement with the measured values. The concentrations of BOD_(5), COD, total suspended solids(TSS), orthophosphate (PO₄-P), and ammonia nitrogen(NH₃-N) were increased by stair style at the segment of 7.0~11.0 ㎞ where input waste loads were directly coming from the downtown of Milyang City. The water quality of downstreams after this stair-style increase was not recovered as before. The increases of carboneous organic, nitrogen and phosphorus showed the limitation of purification capacity downstreams before joing to the Nakdong River.

1. The forest owned by 964 temples belonging to Korean Buddhism Jo-Gye order and registered as of 21 May, 1969 according to the special Act for Transferring of the forest is 85,605ha in area. The temple forest has, as its first and foremost purpose, a religious purpose to maintain scenic beauty and to glorify the temples to increase the Buddhistic faith in those who visit the temples. Therefore, any economical consideration, such as timber production, should be secondary. 2. The protect forest in Korea designated by the article 18 of forest Act is 747,373ha in area and of it, the protect forest for Recreation, public health, and forestscape is 93,132ha, 26.5% of which (24,809ha) is the temple forest. (Table No:2) Furthurmore of all the temple ferest of 85,605ha, 24,809ha (28.9%) is protect forest for forestscape which implies that The Temple forest is of vital importance to the health and recreation of the nation. if we investigate the figur by the forest area of each Temple, the result is as follows: The numbler of Temples whose forest is completely disignated as the Protect forest for forestscape:30(7,768ha) The number of temples more than 70% of whose forest is designated as the protect forest for forestscape: 17 (6,781ha) The figure suggests that both the temple forest and the protect forest for forest scape have the same and common purposes and should be treated with the same technique based upon the asthetic value. 3. The developed and developing nations, including Korea, face such problems as population, urbinization, and pollution while welfare and recreoction problem of the people resulting from the forestscape development became acute and vital. It is incresingly evident that the ideal working plan and praticial method of protect forest fer forestscape was aimed in this study. 4. The guide line--species, silviculture system, rotation, and cutting year--for the management of the forestscape was studied in the view of the aesthetic value. 5. The authers worked out the forestscape working plan based upon the foregoing idea, selecting 646.67ha of the Jik-ji sa. temple of Kyung Sang buk-do, Korea. the forestscape working plan (1) the selection of tree species. (2) Silviculture system. (3) Rotation and cutting year. (4) plan of reforestation and tending 6. The Korean buddhist order must work out the policy of the temple forest management to create and maintain the scenic beauty and all the temples belonging to the order are storongly recommended to organize the special staffs and appropriate the special budget for that nearest future 7. It is also strongly suggested for the government in establish the policy of the management of protect forest for forest scape to increase its economic Value, systematizing the aesthetic Value.
