The world demand of ethanol as an alternative fuel for gasoline is increasing rapidly because of high oil price and global climate change. Most of ethanol is currently produced from corn grain or sugars in sugarcane and sugar beet. Because these sources compete with foods and animal feed and are not expected to be enough for future demand of ethanol. Thus, cellulosic ethanol from agricultural residues or wood has to be commercialized in near future. Typical cellulosic ethanol production consists of pretreatment, enzyme hydrolysis, fermentation and product separation. This paper reviews the principles and status of each step and discusses issues for cellulosic ethanol production.

Korean lawn, Zoysia japonica STEUD, is the type of a perennial warm-season lawn grass that has a naturally green period during 5 months from May to September. This study was carried out to detect the effects of N-P-K fertilization, regrowth capacity after mowing and chlorophyll contents on prolongation of the green period in Zoysia japonica grasslands. The results obtained are summarized as follows: 1. The effects of nitrogen fertilizer application on Zoysia japonica grasslands were affected on regrowth capacity after mowing, green color of leaf canopies and chlorophyll contents, respectively. 2. A the experimental plots which applied 45g/$m^2$/10 weeks of $N_3$ fertilizer, there were high significant effects on prolongation of the green period and the plots of phosphorus and potassium had additive effects. 3. Prolongation of the green period to the last ten days of October was obviously possible by slow degrees in proportion to increment of N-P-K fertilization. 4. However, it is interpreted that more prolongation of the green period is impossible with N-P-K fertilization and irrigation treatments, unless the intermediate turfgrasses between $C_3$ and $C_4$ plants must be found and bred.

In Lentinus edodes(oak mushroom) cultivation, commonly are logs and sawdusts of oak and some other broadleaved tree species used. Recently oak trees have been substantially diminished due to extensive logging. Thus, to develop comparable synthetic formula using other tree species for the cultivation of Lentinus edodes, we investigated the effect of various nutrients and pretreatment on L. edodes mycelial growth in coniferous sawdusts(i.e., Pine and Larch). We found that 1.5 hr pretreatment of sawdust with hot water and adding 10% rice bran, 3% charcoal, 0.02% $NH_4CI$ and 0.5-1% lignosulfornic acid were effective for the growth of L. edodes in pine sawdust media. In larch sawdust pretreatment with acetone for one hr and adding 20% rice bran, 3% charcoal and 0.02% $NH_4CI$ increased L. edodes mycelial growth. We also analyzed the components of oak and coniferous sawdusts and found oak has higher content of xylose and lower content of lignin, arabinose and mannose than conifers. Rice bran, compared with BITEL(HOKKEN Co.) known for better commercial substitute for rice bran, has lower content of xylose and galactose, but the similar C/N ratio.
Background : A continuous healthcare quality improvement is needed to provide high quality healthcare service as well as to maintain trust in terms of satisfying the needs of the patients. Recently it also became an essential issue. in hospital management, recognized for it's competitive potentiality among healthcare organization groups. This study was conducted to analyze patient complaints and issues received by the Quality Improvement Department. Its purpose is to improve healthcare qualities within the hospital, as well as establish policies and appropriate strategies in hospital management. Method : From July 1st to September 30th of the year 1999, we analyzed all complaints and issues made by various patients and their families, which were received through 24 hour phone consultation, numerous suggestion boxes, letters and E-mails, The issues were classified into 16 different categories based on a Patient Satisfaction Assessment Tool. All data were segregated according to the departmental frequencies and their contents. To come up with for environmental and patient satisfaction improvement, all complaints or issues were communicated with hospital administrators, medical and nursing staff and employees. Comprehensive customer satisfaction activities including improving phone etiquette were discussed in Customer Satisfaction Team, CQI Team and each Department. All opportunities for improvement were implemented. Feedback actions were discussed. Results : A total of 317 cases were collected. Issues regarding parking and other accommodation facilities were most common complaints that were 14.5% of total. Issues regarding admission rooms (10.7%), admission procedures (10.7%), waiting room environment (8.8%), nurses and nurse assistants (7.6%), physicians (6.6%) and others (23%) followed. Thirteen of 45 departments received more than 8 complaints. The Nursing Department had the most complaint, receiving 9.8% of total complaints. Complaints regarding the Nursing Department were predominantly related to the environment of patient rooms. The Department of Psychiatry for phone etiquette (4.7%), Department of Otolaryngology for the nursing staff's attitude and phone etiquette (4.4%), and the Admission Department followed. As a part of efforts to improve patient satisfaction, a new parking structure was built and reallocation of the parking space was done. Renovation of other accommodation facilities were carried out by hospital administration, Monthly phone call and answering attitude survey was done by QI Department. Based on this survey we made a phone etiquette manual and distributed throughout the hospital. Compare to the last year, Patient Satisfaction Index measured by Korea Productivity Center using National Customer Satisfaction Index was improved 7 points. According to our organization's own study, we confirmed the phone etiquette was improved 11% than last year. Conclusions : Issues related to parking and other accommodation facilities ranked first followed by complaints made regarding the patient care area, the admission and cashier process, and nurses' and doctors' attitude. The Nursing and Psychiatry Departments need improvement regarding phone etiquette. Results were shared and played a vital role in policymaking and strategic planning of the hospital. It is imperative that we keep our database updated by listening to and solving the needs of each patient. The CQI activities can be achieved only by full commitment of the hospital top management supported by related personal.

In order to establish highly efficient gene transfer condition at early stage of soybean transformation, various experiments were performed and compared their efficiencies by transient GUS analysis; those conditions are genotype determination of Korean soybean cultivars for amenability to Agro-infection, appropriate agar and selective agent concentration, orientation of explant placement, hormone pre-culture, and liquid selection condition. In the genotype screen of Korean soybean varieties, 14 amenable genotypes were selected. For efficient Agrobacterium washing, cefotaxime was chosen and hygromycin at the concentration of 10 and 15 ppm was used as selection agent in the media. Agar concentration was slightly better in 0.6% and 0.8% for both shoot and callus formation, and explant placement with adaxial side down showed high frequency of GUS expression. For wounding treatment, oriental needle was efficient than scalpel for shoot formation and gene transfer. To increase the frequency of gene transfer, hormone pre-treatment was applied. BA at the concentration of 5 and 10 ppm resulted in better survival at the late stage of selection in shoot elongation media. Selection in liquid media after hormone pre-treatment seemed to be effective to remove the escaped non-transformants at early stage of procedure. Considering the results obtained, Eunhakong could be the first choice as a material for soybean transformation among Korean soybean genotypes.
The five fish meal kojis which contained various ratios of barley were prepared and processed to produce six different fish-soy sauces. The chemical compositions including enzyme activities during fermentation were determined and sensory evaluation was done and changes of absorbance during heating process were also measured. The contents of reducing sugar increased until 12 hours, then slightly decreased and maintained constant level after 36 hours during koji making. The contents of total nitrogen were proportional to the amount of fish meal used in koji. The activities of amylase and protease were increased until 48 hours and then were not changed during koji making. The contents of reducing sugar were increased until 50 days and then were not much changed during koji making. The contents of nitrogen and amino nitrogen in sauces were increased gradually during fermentation. The total acid contents of sauces were increased until 70 days, after which it was constant during fermentation. The absorbances of sauces were increased with time during heating process. In sensory test, the fish-soy sauce the ratio of fish meal: barley of which was 10 : 16 received the highest score for flavor of sauce and the conventional soy sauce, for color and taste in a soup test. Fish-soy sauce resulted good quality when the ratio of fish meal to barley was 10 to 13 and 10 to 16.

This study was carried out to investigate growth characteristics, yield, chemical compositions and nutrients yield of corn hybrids for silage in the newly reclaimed hilly land. The experimental design was arranged in a randomized block design with three replications. The seeding time was at May 6. The harvest time of four treatments was milk stage (97 days), dough stage (105 days), yellow stage (112 days) and late yellow stage (119 days after seeding). Plant height, ear height, leaf numbers and ear length were highest in yellow stage (p<0.05, 0.01), but dead leaf, stem hardness and sugar degree (Brix) were higher in late yellow than other treatments. Leaf width, tip filling degree and fresh yield were not significantly different. Dry matter yield increased as the maturity stage progressed (p<0.01). Crude protein and crude fat were not significantly different. NDF and ADF decreased as the maturity stage progressed (p<0.01). Ca content was the highest at milk stage (p<0.05), Fe and P were the highest at dough stage (p<0.05, 0.01). However another minerals were not significantly different. Essential amino acid (EAA), nonessential amino acid (NEAA) and total amino acid were highest at yellow stage, but no significant differences were found among the treatments. Total free sugar contents were higher in the order of Milk > dough > yellow > late yellow stage, but no significant differences were found among the treatments. Crude protein yield was the highest at yellow stage, but crude fat yield, amino acid yield and TDN yield were highest at late yellow stage (p<0.01). Total mineral yield showed no significant difference. Based on the above results, yellow and late yellow stage compared to other maturity stage have been shown to increase dry matter yield and nutrients yield, when silage corn grow cultivate in the newly reclaimed hilly land.

The formation of brown-colored precipitates is one of the serious problems frequently encountered in the development and supply of groundwater in Korea, because by it the water exceeds the drinking water standard in terms of color. taste. turbidity and dissolved iron concentration and of often results in scaling problem within the water supplying system. In groundwaters from the Pajoo area, brown precipitates are typically formed in a few hours after pumping-out. In this paper we examine the process of the brown precipitates' formation using the equilibrium thermodynamic and kinetic approaches, in order to understand the origin and geochemical pathway of the generation of turbidity in groundwater. The results of this study are used to suggest not only the proper pumping technique to minimize the formation of precipitates but also the optimal design of water treatment methods to improve the water quality. The bed-rock groundwater in the Pajoo area belongs to the Ca-$HCO_3$type that was evolved through water/rock (gneiss) interaction. Based on SEM-EDS and XRD analyses, the precipitates are identified as an amorphous, Fe-bearing oxides or hydroxides. By the use of multi-step filtration with pore sizes of 6, 4, 1, 0.45 and 0.2 $\mu\textrm{m}$, the precipitates mostly fall in the colloidal size (1 to 0.45 $\mu\textrm{m}$) but are concentrated (about 81%) in the range of 1 to 6 $\mu\textrm{m}$in teams of mass (weight) distribution. Large amounts of dissolved iron were possibly originated from dissolution of clinochlore in cataclasite which contains high amounts of Fe (up to 3 wt.%). The calculation of saturation index (using a computer code PHREEQC), as well as the examination of pH-Eh stability relations, also indicate that the final precipitates are Fe-oxy-hydroxide that is formed by the change of water chemistry (mainly, oxidation) due to the exposure to oxygen during the pumping-out of Fe(II)-bearing, reduced groundwater. After pumping-out, the groundwater shows the progressive decreases of pH, DO and alkalinity with elapsed time. However, turbidity increases and then decreases with time. The decrease of dissolved Fe concentration as a function of elapsed time after pumping-out is expressed as a regression equation Fe(II)=10.l exp(-0.0009t). The oxidation reaction due to the influx of free oxygen during the pumping and storage of groundwater results in the formation of brown precipitates, which is dependent on time, $Po_2$and pH. In order to obtain drinkable water quality, therefore, the precipitates should be removed by filtering after the stepwise storage and aeration in tanks with sufficient volume for sufficient time. Particle size distribution data also suggest that step-wise filtration would be cost-effective. To minimize the scaling within wells, the continued (if possible) pumping within the optimum pumping rate is recommended because this technique will be most effective for minimizing the mixing between deep Fe(II)-rich water and shallow $O_2$-rich water. The simultaneous pumping of shallow $O_2$-rich water in different wells is also recommended.
