This study analyzed the necessity of the tentatively-named "Framework Act on Landscape Architecture" as an umbrella law in the field of landscape architecture regarding legal, industrial, and academic aspects and is intended to provide basic data to suggest the optimal legal system and legislative proceedings to control it. This study can be summarized as follows: First, a form of framework act on landscape architecture is appropriate for a compromise between ideal type and political framework. Some content is suitable for proclamatory character including present and future issue related to the landscape architecture fields. Second, legislative proceedings are more reasonable as motions coming from assembly proposals rather than government. Motions by assembly proposal recommend the following procedure: submission of a legislative bill by an assemblyperson, passing of a permanent commission, review by government, leading approval by emphasis on correspondence with the principle to carry out government affairs, proclamation. Third, a frame based on content and form can be made up of a total of 7 chapters 34 articles. The function must include the following: the suggestion of direction for government policy, the systematization of the institution and what it includes, the control of government administration, a public service system regarding public relations for landscape architecture and so on. The results of this study will form a social consensus about the necessity of a framework act regarding landscape architecture fields and contribute to informing the importance of landscape architecture as related to other industrial fields.

The present study was conducted to establish an effect and a proper concentration for treatment with gibberellic acid ($GA_3$) and thidiazuron (TDZ), resulting with increase berry size and yield in Gaeryangmeoru grapes. Berry size was increased by treatment with $GA_3$, and the fruit clusters obtained for the groups treated with $GA_3$ concentrations of 100 and $200mg{\cdot}L^{-1}$ were bigger. The berry number was also enhanced in $GA_3$ treated groups, but the soluble solid content and acidity was not significantly different. Damage caused by $GA_3$ treatment, such as peel pollination and berry shatter, was observed in the group with $200mg{\cdot}L^{-1}$. The berry size was larger in group treated with a high concentration of $GA_3$ and TDZ respectively than in those treated with low concentrations in the treatment mixed $GA_3$ and TDZ; however, fruit with low soluble solid content and high acidity was harvested after $GA_3$ and TDZ treatment due to delay of berry ripening. The pericarp tissue layers were not changed, but the distance from the epidermis layer to vascular bundle tissue was increased as a result of $GA_3$ and TDZ treatment. Therefore, $GA_3$ and TDZ did not affect an cell division but not cell size, resulting in an enlarged berry size. It is necessary to treat plant growth regulators 2~3 times and immediately after berry set to enhance berry set rate, because the period of berry set is short. This study suggests that the proper concentration for enhancing berry size and set were up to $100mg{\cdot}L^1$ $GA_3$ or $50mg{\cdot}L^{-1}GA_3+1.25mg{\cdot}L^{-1}$ TDZ, and it is necessary to pay attention to harvest mature fruits because of the delay of ripening caused by the usage of TDZ.

The objective of this study was to investigate the effect of restricted feeding to laying performance and egg quality in brown layers. A total of 1,080 brown layer chicks were divided into three treatments; conventional feeding (ad libitum) and two restricted feedings (80% of conventional diet) for 70 weeks. One of restricted feeding started from six to eighteen weeks of age, and the other started from twelve to eighteen weeks of age. Diets were formulated by NRC (1994) recommendation. Overall laying performance and feed intake were the highest in $6{\sim}18 wk$ restricted group. But there was no significant difference among treatment group (P>0.05). Feed intake was higher in $6{\sim}18 wk$ restricted group during maximum production (P<0.05), but there was no difference between treatments after the peak. Egg quality tended to decreased by aging, but there was no significant difference among the treatments (P>0.05). The result of present study indicated that restricted feeding in rearing period of layers is beneficial to improve egg productivity and to reduce feed cost.

This study was conducted to know the optimal supplementary level of spent mushroom substrates (Flammulina velutipes) as an energy source and fermentation period in manufacturing of rye silage. Whole crop rye was harvested at full bloom stage and ensiled with spent mushroom substrates of 20%(S-20), 40%(S-40) and 60%(S-60) as fresh matter basis. Each silage was prepared in plastic buckets included with vinyl bag by three replications and fermented for 3, 6 and 9 weeks, respectively. Moisture contents of whole crop rye at full bloom stage and spent mushroom substrates were 62.3% and 54.3%, respectively, and those of silages was ranged from 58% to 64%. Ether extracts content of silages was significantly (P<0.05) increased in 6 weeks of fermentation period. The pH of silages ranged from 4.46 to 5.05, and fluctuated in the changes by fermentation period beside of decreased with elapsing the period in the S-60. The organic acid content of silages was higher in the order of lactic acid, butyric acid, acetic acid and propionic acid. Lactic acid content was higher when fermented for 6 weeks compared to the other fermentation period. Flieg's score for estimation of silage quality ranged from 63 to 80, and was relatively high level in the S-20 and the S-40 fermented for 6 weeks, and was high level in S-20, and was relatively low level in the silages fermented for 3 week. Hence, we suggest that supplementation of 20% spent mushroom substrates in fresh matter basis and fermentation for 6 weeks are resonable for a good quality of rye silage.

This study was carried out to investigate the changes of physicochemical characteristics of Schizandra chinensis during postharvest ripening for 8 days at various temperatures. The juice yield of S. chinensis, which was 55.7% before postharvest ripening, was unchanged $(55.3{\pm}0.6-56.3{\pm}0.6%)$ at $4^{\circ}C$ storage, but was decreased at the level of 6 and 7% at $25^{\circ}C$ and room temperature (RT), respectively. During storage at $25^{\circ}C$ and RT, the titratable acidities of S. chinensis were the highest at $7.49{\pm}0.03$ and $7.20{\pm}0.03%$ after 6 days of postharvest ripening, respectively. During storage at $25^{\circ}C$ and RT, the soluble solid content of S. chinensis was increased from $8.2{\pm}0.1%$ at initial stage to a peak of $12.2{\pm}0.15%$ at 6-day storage, after which it decreased. L values (lightness) of S. chinensis were increased in all treatments during storage, and a values (redness) of $25^{\circ}C$ and RT treatments were increased from 5.04 initially to 6.77 and 7.65 at 8-day storage, respectively. The major free sugars of S. chinensis were fructose (0.55%), glucose (0.56%), and sucrose (0.50%). During storage at $25^{\circ}C$ and RT, the fructose and glucose contents were continually increased with increasing storage period, while the sucrose contents decreased after 6-day storage. Major non-volatile organic acids of S. chinensis were succinic (1.21%), citric (0.17%), and malic (0.07%) acids. Changes in the organic acids contents of S. chinensis at various temperatures showed a similar tendency to that of the free sugars. We estimated that the best conditions for the postharvest ripening of S. chinensis were 8 days at $4^{\circ}C$ storage, and 6 days at $25^{\circ}C$ and RT.

There are around 7,500 manure tanks to treat the manures from pigs in Korea. In the tank, there are too much sediments deposited on the base and wall, which causes low efficiency of stock capacity and manure fermentation. In order to minimize sediments and to ferment manure effectively, we developed a 2-fluid jet mixer for mixing sediments in liquid livestock manure tank. For developing the prototype, we tested a factorial experimental system with various nozzles, and simulated CFD models with two kinds of nozzle arrangement. From the results of factorial experiment and CFD simulation, we concluded the dia. ratio of primary : secondary nozzle should be 1:2 and the nozzles should be arranged at the same distances toward to the circumferential direction. With this results, we manufactured a 2-fluid jet mixer which is consists of four 2-phase nozzles, centrifugal slurry pump and root's type air blower. And, we carried out the performance test of the prototype in the round shaped liquid manure tank in the farm. The performance test results showed that the uniformity of TS (Total Solid) and VS (Volatile Solid) was raised from 21.3 g/L, 13.3 g/L In steady state to TS and VS to 23.0 g/L, 14.1 g/L in the mixing operation. Therefore, we could conclude that the prototype of 2-fluid mixer could make the solid material which could be sediments in the tank not to be deposited in the tank and to be contacted to air bubbles which could enhance the efficiency of the fermentation of livestock manure.

Background: A retrospective study was conducted to analyze the results of St. Jude Medical mitral valve replacement at the Chonbuk National University Hospital since the initial implant in May 1984. Material and Method: Between May of 1984 and December of 1996, 95 patients underwent MVR with the St. Jude Medical mechanical valve prosthesis at Department of Medical Science of Chonbuk National University Hospital and follow-up ended in May of 2004. Result: Age ranged from 19 to 69 years. Follow-up (mean${\pm}$standard deviation) averaged $10.6{\pm}4.2\;year$. Thirty-day operative mortality was 4.2% (4/95). Nine late deaths have occurred and actuarial survival was $90.5{\pm}3.0%,\;87.9{\pm}3.4%\;and\;83.2{\pm}4.6%$ at 5, 10 and 20 years, respectively. Probability of freedom from valve-rotated death was $95.5{\pm}2.1%,\;94.3{\pm}2.4%\;and\;91.0{\pm}3.9%$ at 5, 10 and 20 years, respectively. Seven patients have sustained thromboembolic events (1,05%/patient-year). Fifteen patients had anticoagulation related hemorrhage (3.56%/patient-year). There was no structural valve deterioration. Probability of freedom from all complications was $82.0{\pm}3.9%,\;71.3{\pm}4.8%\;and\;42.4{\pm}10.5%$ at 5, 10 and 20 years, respectively. Conclusion: We confirm the effective and excellent durability of the St. Jude Medical prosthesis in the mitral position with a low event rate at long-term follow-up. It also demonstrates the commonly encountered practical difficulty of adjusting the anti-coagulation protocol in patients with prosthetic mitral valves.

The process for ethanol production requires lignocellulosic biomass to be hydrolyzed to generate monomeric sugars for the fermentation. During hydrolysis step, a monomeric sugars and a broad range of inhibitory compounds (furan derivatives, weak acids, phenolics) are formed and released. In this study, we investigated the effects of inhibitory compounds on the fermentative performance of Saccharomyces cerevisiae K35 and Pichia stipitis KCCM 12009 in ethanol production, two yeast strains were fermented in the synthetic medium including six inhibitory compounds such as 5-hydroxymethylfurfura (5-HMF), furfural, acetic acid, syringaldehyde, vanillic acid and syringic acid. Ethanol of over 40 g/L was produced by two yeast strains in the absence of inhibitory compounds, respectively. Most inhibitory compounds except acetic acid had a little effect on the ethanol production, but acetic acid showed high inhibition effect on the cell growth and ethanol production.
