${\beta}-PbO_2$ electrode, which was electrodeposited on Ti madras, was prepared and for the decomposition of cyanide in electroplating wastewater. After the investigation of temperature and pH conditions for no hydrogen cyanide evolution during the decomposition of cyanide, the optimum current densities of ${\beta}-PbO_2$ electrodeposition and cyanide decomposition were determined in 500ppm NaCN solution, and durability of ${\beta}-PbO_2$ electrode was also investigated. Hydrogen cyanide was actively generated above $40^{\circ}C$ and was not evolved above pH 13. ${\beta}-PbO_2$ electrode electodeposited at $5A/dm^2$ showed the best cyanide decomposition efficiency The decompostion efficiency was about 70% at low decomposition current density ($0.08A/dm^2$), and it decreased gradually to about 10% as the decomposition current density increased up to $4A/dm^2$. The film of ${\beta}-PbO_2$ electrodeposited was corrosive at $20A/dm^2$ and was broken at $50A/dm^2$.

This study, collaborated Gifu University, Japan, was performed to analyze chemical pollutants and microorganism and to clarify the distribution of sulfate-reducing bacteria and their insolubilization of heavy metal ions in leachates sampled seasonally between 1994 and 1996 from Nanjido waste landfill site, sampled 4 times between 1995 and 1996 from Pusan and Daejeon waste landfill site, and sampled 1 time between 1992 and 1994 from Hokkaido, Nagoya, Osaka and Hukuoka waste landfill site in Japan. The results were as follows: 1. The temperatures of internal leachate and leachate effluent were 40$\circ$C and 30$\circ$C, respectively, and the pH values of both leachates were about 8.0 at Nanjido waste landfill site. The concentration of SO$_4^{-2}$ gradually increased with the degree of stabilization and that of NO$_3$-N was detected in a part of sampling sites at one and half years, and in all sampling sites at 3 years after completion of landfill. 2. The organic substances in leachate of Nanjido waste landfill site decreased with the degree of stabilization and they were very fluctuated with measuring point and time. The concentration of organic substance and heavy metals in internal leachate were higher than in leachate effluent and those of Cd, Hg, and Pb were lower than detection limit except a part of samples in 1996. 3. APCs in internal leachate and leachate effluent were not much different and the minimum of APCs in internal leachate and leachate effluent were $1.0\times 10^4$/ml and $4.0\times 10^1$/ml, respectively. 4. The maximums of SRBs in Nanjido, Pusan, and Daejeon waste landfill site were 9180 MPN/ml, 24000 MPN/ml, and 348 MPN/ml, respectively and the maximum of SRBs in Japan waste landfill site was 9300 MPN/ml. 5. During 2-week-SRB culture, the values of MPN were high at 50$\circ$C for initial culture period and at 30$\circ$C for last culture period. MPN started to appear at first day and rapidly increased between 7th day and 9th day. 6. Cadmium and copper were insolubilized by SRB within 6 hr and iron and zinc were done within 48 hr. The rates of insolubilization of Cd, Cu, Fe, Zn, T-Cr were 100%, 99.5%, 95.0%, 99.8%, 16.1% after 48 hr treatment with SRB, respectively.

The purpose of this study was to measure and determine the relationship of femoral neck and lumbar bone mineral density with their and related factors. It were measured and determined the relationships among bone mineral density, bone mineral content in the lumbar and femoral neck, muscle strength (arm, back, leg), muscle endurance, instrumental activity of daily living (IADL), quality of life, cognitive perceptual variables(self efficacy, perceived health status), age, age at menopausal period. The twenty five subjects participating in this study consisted of twelve males and thirteen females at a C-institution in Chung Buk province. The mean age of subjects was 73.64 years. The data was collected from August, 1993 to September, 1993. The data was analyzed with $x^2-test$, t-test, Correlation, multiple regression using a SPSS pc+ program. 1. The mean femoral neck bone mineral density was $0.636g/cm^2$, 66.7% of young bone mineral density, the mean lumbar($L_2-L_4$) bone mineral density was $0.807g/cm^2$, 79.86% of young bone mineral density. The mean fermoral neck bone mineral content was 2.906g and the mean lumbar bone mineral content was 36.898g. 2. The mean muscle strength was 17.14kg(grip strength), 32.05kg(back lift strength), 17.14kg (leg lift strength) and the mean muscle endurance was 9.92times. 3. Men showed a significantly higher score (p<0.01) in muscle strength and muscle endurance than women, as well as a significantly higher score on self efficacy and perceived health status(p<0.05). 4. The femur neck bone mineral density had a significant correlation(p<0.0l) with leg lift strength, back lift strength, and their was a significant correlations (p<0.05) with arm strength and muscle endurance. Lumbar ($L_2-L_2$) bone mineral density had a significant correlation(p<0.05) with muscle endurance, grip strength and IADL. 5. With the multiple regression analysis the most significant predictor for lumbar bone mineral density were IADL, the most significant predictor for femoral neck bone mineral density was leg strength. This study concluded: As the mean bone mineral density and bone mineral content were low, the aged showed osteopenia. Bone mineral density, muscle strength and IADL were correlated. The aged could pro mote muscle strength, bone mineral density and IADL through Leg Press exercise which was safe and efficient for the aged. This Leg Press exercise contributed to prevention of osteoporosis and promoted the health of the aged.

The purpose of this study is to promote health for young female workers. It is based on questionnaires collected from 215 female workers in Incheon area. This study includes health condition (fatigue scores), occupational disease, knowledge of abused drugs and the actual condition of drug use. The results are summerized as follows: - $47.4\%$ visited their health center and were treated with diseases like cold and headache $(34.9\%)$, gastroenteric disease $(6.5\%)$, trauma $(7.9\%)$ and chronic disease such as diabetes and hypertension $(3.3\%)$ - $44.7\%$ received regular health education and $4.7\%$ among them received education on abused drugs. - $20.5\%$ were suffering from work related diseases such as gastroenteric disease, headache, trauma, repiratory disease, skin problem, arthritis, low back pain, shortsightness and tuberculosis. - Total mean fatigue score as an indication of health status was $9.0\pm5.4$ points out of 30 points. Physical mean score (group I) was $3.92\pm2.2$ points and psychological mean score was $2.5\pm2.3$ points and neurosensory mean score was $2.6\pm2.1$ points out of each 10 points. - They recognized analgesics $(55.0\%)$ and the next are laxatives $(49.8\%)$, inhalants $(40.0\%)$, narcotics $(24.2\%)$, stimulants $(24.0\%)$, antihistamines$(5.9\%)$, diuretics $(3.0\%)$, tranquilizer $(2.4\%)$ and sedatives $(1.4\%)$ - They used analgesics $(37.2\%)$ the most and then laxatives $(6.0\%)$, stimulants$(5.6\%)$, diuretics $(1.9\%)$, antihistamines$(0.5\%)$, And nobody used tranquilizer, sedatives, narcotics and inhalant. - The relationship between career, drug abuse education, health center utilization and and the actual condition of drug using was examined. The longer the career and the more educated with drug abuse, the less drug used. And those who utilized health center rarely used more drugs. - The relationship between career, health center utilization, the score of fatigue and use of analgesics was also examined. Those group who have a longer career above 3 years and the group who have never used health center used more analgesics. And the group of fatigue score above 11.0 points used a little more analgesics than the other group. These results indicate that analgesics are the most frequent used drugs among female workers. Those analgesics such as geborin, penzal, saridon, aspirin, tyrenol should be used properly. These basic data is submitted for the education and consultation which are carried out by industrial nurses for promoting health of industrial workers.

Effects of dietary protein levels on the manifestations of the toxicity of gramoxone, a bipyridine herbicide, in the liver of rats were investigated. The addition of gramoxone, with regard to the body weight and feed efficiency ratio of rats, had a move dramatic effect on animals fed a low or intermediate protein diet than for those similarly treated among rats fed a relatively high protein diet. Lipid content in the rat liver tended to increase with the addition of gramoxone into each protein diet, with the exception of the high protein-gramoxone diet. The addition of gramoxone tended to increase hepatic TBA value significantly in rats, especially among those fed the low protein-gramoxone diet or the control-gramoxone diet. Significant morphological changes, including fat changes of hepatic cells and increases in the number of Kupffer cells, were found both in rats fed the low protein diet and those fed any of the gramoxone-treated diets. fat changes within hepatic cells were found to be especially severe in rats fed the low protein-gramoxone diet. Distributions of glycogen in rat liver appeared to increase in rats fed any of the diets to which gramoxone had been added.

An alkaline pretense Producing microorganism was isolated from Korean traditional soy sauce and identified as Bacillus subtilis CCKS-111. The optimum culture condition of Bacillus subtilis CCKS-111 for the production of alkaline pretense was as follow: 2% soluble starch, 0.2% peptone, 0.1% (NB$_4$)$_2$S$_2$O$_{8}$ , 0.2% MgSO$_4$, pH 7.0, 35$^{\circ}C$ and 24hrs. The optimum pH and temperature for the enzyme activity of alkaline pretense producing Bacillus subtilis CCKS-111 were pH 9.0 and 5$0^{\circ}C$, respectively. The enzyme was relatively stable at pH 6.0~11.0 and at temperature below 4$0^{\circ}C$. The activity of the enzyme was inhibited by $K^{+}$ and Hg$^{2+}$, whereas Cu$^{2+}$ exhibited rather activating effects on the enzyme activity. Ethylenediaminetetraacetic acid and phenylmethanesulfonyl fluoride inhibited the enzyme activity. This indicates that this is serine pretense which requires metal ion group for the enzyme activity. Km value was 2.313$\times$10$^{-4}$ M/L, V$_{max}$ value was 39.216$\mu\textrm{g}$/min. This enzyme hydrolyzed casein more rapidly than the hemoglobin.lobin.

Some sugars and proteins were mixed with yellow corvenia lipids, soybean lipids or see yolk lipids to study the influence of the sugars or proteins on lipid oxidation and browning in dry and wet system during kept at $40^{\circ}C$. In the yellow corvenia lipids mixed with various food components, peroxide value(POV), carbonyl value(COV) and brown pigments were much higher than the case that soybean lipids or egg folk lipids were mixed. In terms of the food components, they appealed high in glucose, sucrose and starch but low in albumin and casein. When the soybean lipids were mixed, POV appeared low in all these maxture. COV and brown pigments appeared high in glucose, sucrose and starch but low in albumin and casein. In the case of egg york lipids, POV appeared lower than that of soybean lipids but COV and brown pigments were similar. In the starch mixture of three lipids in wet system, POV and COV in yellow corvenia lipids appealed lower, but appeared higher in soybean lipids and egg yolk lipids than those in dry system. Brown pigments appeared similarly with the case in dry system. And the all mixtures of casein in wet system, POV and COV appealed lower thanthose of the dry system, but brown pigments appeared high.

Studies were carried out to determined the optimal conditions of processing and changes in trypsin indigestible substrate(TIS) and in vitro protein digestibility of paddy grasshopper(Oxya chinensis formosana) under various drying conditions. The multienzyme assy and amino acid compositions were used to predict the quality changes of dried products. The in vitro protein digestidility of defatted products were higher than that of sun and hot air dried products. This results indicated that heat processing is decreased the digestibility, but is increased the TIS contents of dried samples. Amino acid composition of the products was comparable to the ANRC casein scoring pattern. The protein was espeoially low in the amount of lysine, tryptophan and methionine, but high in the quantity of aspartic acid, glutamic acid and arginine indicating that it could be a difference of the dry processing. C-PER and DC-PER were 2.65 and 2.44, respectively, in the defatted and freeze dried products and 2.49 and 2.30, respectively, in hot air dried products. From the these results, it could be confirmed that defatted and freeze dried products might be utilized with feed or foodstuff, unless the toxic substances were no longer detectable.

As a professional occupation, landscape education focuses on fostering professional human resources and is one of the major axes of the landscape industry. In this study, a survey of landscape students on their learning and pedagogics was conducted with the aim to present basic information for the improvement of teaching on landscape construction. A total of 348 people answered 14 questions in the category of the impression of landscape construction classes included in the questionnaire. The results showed that the students found landscape construction classes academically important and recognized the necessity for completing these classes, but they were not satisfied with the learning environments and pedagogics used in these classes. They found what they learned not readily applicable to actual practice and saw these classes as part of their preparations for the landscape engineer qualification test. Their demands in relation to the classes included field practice-oriented teaching and participation in various programs for field practice, which highlights the necessity for human resource management-oriented classes that cover planning, design, construction, and management. Challenges in relation to field practice included the provision of environment, for example offering a variety of opportunities and improving treatment in practice. This study has significance in that it analyzed the views of students and discussed directions for future improvement since there is a lack of studies and discussions about education in the field of landscape construction. This study also has a limitation that only four-year universities were included in the study. Comprehensive studies including investigating junior college and graduate school curricula and case studies of landscape construction curricula overseas are needed in the future.
