The shortage of nursing personnel was become one of the most serious problems in operating pediatric oncology nursing unit which was the first pediatric oncology nursing unit in Korea. The purpose of this study was to estimate the optimal number of nursing personnel by calculating nursing care hours. The subjects were 13 staff nurses and inpatients of pediatric oncology nursing unit at Seoul National University Hospital during the period of May 20, 1996, to June 2, 1996. The number of nurses' duty was 132, the number of patients treated was 1288 for these 2 weeks. The tools used for this study were pediatric patient classification indexes and direct & indirect care indexes. Each nurse measured the time that they spent for their activities by self record under the supervision of their nurse manager. The method used to calculate the number of nursing personnel was multiplication of the average number of nursing care hours per patient per day with the number of patients. Percentage, average, t-test, F-test were used for data analysis. The results of this study were as follows : 1) The distribution of patient class : Class I & II none, Class III 86.8%. Class IV 12.9% 2) Direct nursing care hours for a patient per shift according to patient classification: Class III : 27.64 minutes, Class IV : 54.64 minutes The average direct nursing service hours for a patient per shift(3 shift) was 31.54 minutes(94.62 m/day). The average indirect nursing service hours for each patient per duty(3 shift) is 21.3 minutes (63. 91 m/day). 3) The average nursing hours for a patient per duty was 52.80 minutes(2.64h/day). 4) The group of administering medications in direct care activities showed the highest percentage (38.9%). Checking vital signs among observation took the most time am.ong each direct care activity (6.88 minutes for a patient per duty). 5) Charting took the most time of each indirect care activity(52.53 minutes/ duty/nurse). 6) The average personal time per duty is 29.40 minutes, which 'was below 30 minutes of this hospital regulations. 7) The average nursing hours that a nurse provided for a duty was 8.60 hours, which meant that a nurse worked 1.10 hours overtime. 8) Standardizing to a 33 bed to a unit, 17 nurses were needed at the present nursing level.

Recently some Korean feminists have reported the family management agreement (FMA) can contribute to enhance the women farmers' legal status and to improve their farm management. The FMA is a formal document written each rights and responsibilities on the farm management, income allocation, and labor condition such as working time and work-off days agreed among family members. Since 2004, 161 farmer couples have signed and practiced the FMA after two-day workshop scheduled for the agreement. The purpose of this study is to analyze the effects of FMA on the increase of participation in (am management among women farmers. Data were collected from 204 FMA couples through the structured questionnaires. Also interview and participating observation were carried out. Paired t-test were conducted using SPSS 12.0 for Windows program. Major findings were as follows. Women farmers' participation in decision making of farming activities has significantly increased after than before the FMA. However, husbands' participation in decision making is higher than women farmers even after the FMA. After the FMA, labor compensation, regularly or irregularly, for women farmers has increased to 53.3%, 35.3% higher than 18% of the previous study and women farmers' ownership of their farm assets has increased to 48.1% from 29.1%. Also, there is a tendency women farmers' role as a representative of their farm has increased. In conclusion the FMA makes women farmers participate more in farm management as decision maker, income beneficiary, farm asset owner, and farm representative, which encourage them to get the legal status as a farmer and to control their farm management risk. It is suggested that the FMA be selected as a program in order to strengthen the agricultural competitiveness.

우리나라에 있어서 사일리지용 옥수수(Zea mays L.)는 널리 재배가 되고 있지만 실제로 농가의 포장에서 옥수수의 사초로서 이용에 관한 연구 보고가 없는 실정이다. 따라서 경기도 여주 및 이천에서 1988년에 8개 농가 1989년에 13개 낙농가를 선정하여 사일리지용 옥수수의 재배 실태를 연구 조사하였다. 1988년에 농가생산 옥수수의 암이삭 착생주율은 75.3%. ha당 재식밀도는 75,826주, 암이삭 비율은 38.3% 그리고 수확시 건물률은 23.8%. ha당 건물수량은 12,661kg이였으며 1989년도의 암이삭 착생주율은 79.5%, ha당 재식밀도는 79.981주. 암이삭비율은 41.1%. 건물률은 20.7%. ha당 건물수량은 16.152kg 였고 흑조위축병 이병률은 11.9%였다. 그러나 농가가 제조한 옥수수 사일리지의 Flieg's score는 70∼100으로 평균은 91이 되어 품질은 우수한 편이었다. 본 연구조사 결과에 따르면 낙농가는 표준보다 훨씬 높은 재식밀도하에서 만생품종의 옥수수를 재배하고 있었으며 이러한 결과 농가 재배 옥수수의 생산성은 시험기관이 재배하는 옥수수의 생산성 보다 낮았다. 따라서 중·북부지방에서는 현재보다 더 조생품종의 옥수수를 재배하여야 하고 옥수수의 재식 밀도도 낮추어야 할 것이다.

In this study, the adsorption of $Cu^{2+}$ from aqueous solution by the biochar derived from woody biomass at different pyrolysis temperatures has been investigated. The woody biomass wastes used in this study were branch of willow ($Salix$ $koreensis$ $Andersson$) and bark of chestnut ($Castanea$ $crenata$ $var.$ $dulcis$). Three biochar samples prepared by heating each biomass at temperature of $300^{\circ}C$, $500^{\circ}C$, and $700^{\circ}C$were tested for the adsorption capacity of Cu. Also the physicochemical properties of the developed biochars were studied using different characterization techniques such as FT-IR, SEM, BET surface area, and cation exchange capacity (CEC). The adsorption of Cu could be well described by Langmuir model for both willow and chestnut biochars with $R^2{\geq}0.98$. The maximum adsorption capacities of the biochar produced at $700^{\circ}C$ from the Langmuir equation were found to be 12.5 mg $g^{-1}$ and 16.9 mg $g^{-1}$ for willow and chestnut, respectively. Chestnut biochar was found to interact more effectively with the active sites available for Cu, resulting higher removal of Cu(II) than wiloow biochar. Ion exchange and surface complexation found to be the main mechanisms involved in the adsorption process. This study demonstrated the feasibility of the biochars derived from woody biomass to be as a low-cost potential adsorbent for heavy metals as Cu(II) removal in aquatic system.

This study has been conducted to assess blackish-water phenomena in Dam reservoir. To searching for the reason, we survey physical changes in reservoir and analyze metal and organic content in particulate materials and water. The blackish-water phenomena in lake A are occurred with turbidity increases in turnover season irregularly. It was reported on 6 Jan. 2005 weakly and the water column mixed with 35~40m depth and water temperature shows $7^{\circ}C$. The turbidity of AD and AM site increased up to 20NTU. Especially, AN site shows 27NTU, such a result makes that Dam manager conclude it to blackish-water phenomena. The results of sequential extraction analysis show that over 80% of Al, Cr and Fe is existed in residual form in sediment. On the other hand, the most part of Mn shows exchangeable and carbonates form, which have a good possibility of release to water column. Mn contents in pore waters of the sediment samples are also found to be ~4 times higher than Fe contents. The metal contents in pore water of different dam sites are in order of AN (Fe: 9.98, Mn: 40.6) > AD(8.33, 37.5) > DD(1.91, 2.55). According to the results of extracted organic materials from sediment, humic substances is occupied with over 85% in total organic carbon including 23~45% of humic acid (HA) and 0.9~8.5% of fulvic acid (FA). However, HA content in pore water is not detectable while FA contents, acid-soluble humic fractions is higher than that of sediment(10~15%). which indicating that FA is a main humic components affecting water color. The color unit per DOC of FA in pore waters of different dam sites are found to be higher in lake A than lake D. From the results, it could be suggested that blackish-water phenomena of lake A are mainly arise from higher concentration of Mn and water soluble organic fractions (e.g., FA) released from sediments as well as the strength of turnover in Dam reservoir.

The purpose of this study is to examine current foodservice management practices at free congregate meal service for elderly people. Forty seven meal service centers as well as randomly selected Seoul and Kyunggido area were surveyed and interviewed and results were summarized as follows: The cost of each meal(lunch) was ranged from 1,300 won to 1,500 won and 68% of target centers were severed over 100 meals per day. Meal time for lunch begins from 10:30 am to 12:00 because great portion of elderly didn't take breakfast frequently. 52.3% of centers severed meal 5 times per week, just weekdays. 21.3% of centers employeed dietitian, 63.8% of center employeed cook. 95.7% of center were supported labor force by volunteers. Volunteer was important contribution to free meal service. Utilizing the labor force more effectively is thus a major challenge facing manager in each center. Ideal supporting system of free foodstuff, foodbank was still minor source of securing foodstuff. Most of centers(46 centers)served lunch, only one of them served breakfast and lunch. Government was the major financial sponsor, the second of them was religious organization. The large portions of financial support provided only food cost of total meal service budget. Most of center adapted self-service system. Standardized recipes were not developed and meal preparation was controlled under the experience of volunteers. Recording system of nutrition management, production control, storage and inventory control was not adapted by most of sites. It is suggested that in order to meet the change of the patterns of social and family structure, the service of the center should be offended in urban area and it is necessary to develop systematic management models for the center. It was suggested that not only financial support but also systematical support on management by the local government may be necessary to meet the goal of supply nutritionally balanced food at center.
