The aim of this study is to develop a simple and rapid field method for the determination of chloride content in tobacco green or cured leaves. To set up a practical process, several factors such as the proper sampling position of each leaf, the size of leaf lamina pieces for blending, the substitution of deionized water fur the extracting solution, 0.1N $HNO_3$, the submerging durations before blending, and the standing times before measuring were studied using flue-cured and burley tobacco with a stable and reproducible Chloride Meter, KRK CL-2Z. From the results, chloride contents of tobacco leaves could be analyzed with the Chloride Meter(CL-2Z) using the suspension of 14 mm diameter leaf disks after soaking in distilled water for 30 min., blending with a mini-blender for 30 seconds. The chloride contents measured in this way showed highly significant correlations with ones by the conventional potentiometric method using an ion meter-chloride electrode and $AgNO_3$ titration. In our method, the procedures such as drying, powdering and weighing samples, and using chemical reagents for extraction (0.1N $HNO_3$) and titration(0.028N $AgNO_3$) could be eliminated. These results suggest that the newly constructed method using the Chloride Meter is more efficient to determine the chloride content of tobacco leave in comparison with the one by the Ion $Meter:AgNO_3$ titration.

묘삼을 분재배하여 인공기상실 $15^{\circ}C$ 자연광실에서 여러가지 색의 셀로판지를 차광재로로 5~10%의 투광율로 재배하였다. 상대근중9최종생근 중/최초 생근 중)은 청>녹>백>황>적의 순서였다. 지상부 생육 특히 경장은 청색 광하에서 가장 저조하였다. 상대근중은 경장과 부상관을 보였으며 이 관계에서 각 광질은 특수한 영역을 보여 청과 녹이 한 군, 적과 황이 다른 한 군으로 분리되었다. 경장은 주당엽 면적과 전체 또는 각개의 광질내에서 정상관을 보였는데 적색 광에서만 유의성이 없었다. 잎중의 엽록소 a 및 b의 함량 또는 엽록소 a/b 비율은 백>청>녹>적>황의 순이었으며 엽록소 a와 b간, 전엽록소와 a/b 비율간 a/b 비율과 엽록소 a간에 모두 고도의 유의 정상관을 보였다. 이상의 사실들은 청색 차광자재가 인삼생산에 유리할 것임을 보여준다. Ginseng plants in the 2nd year were grown under the shade (90-95%) of colored cellophane films at $15^{\circ}C$ in a natural light phytotron. Relative root grown (final/initial) was in decreasing order of blue, green, white, yellow and red. The growth of aerial part, especially stem length was poorest in blue light with relative root growth negatively correlated with stem length. In this relation each color showed specific domain. Stem length showed positive linear correlation with leaf area per plant in each and among light though it was not significant in red light. The content and ratio of chlorophyll a and b in leaf were in the decreasing order of White, Blue, Green, Red and Yellow. There is positive correlation between chlorophyll a and chlorophyll b, and between total chlorophyll and chl:a/b ratio. Blue color shade is expected to be beneficial for ginseng production.

Studies on effect of Decyl alcohol EC and Butralin EC on tobacco sucker control were conducted in the tobacco field of Agro-tech Research Group of KT&G Central Research Institute, in 2004. Control effects of two chemicals were highest at the sucker length of 1$1\~2cm$. This indicates that the first application of Decyl alcohol should be conducted before button stage in the flue-cured and at the button stage in the burley tobacco. Effects of Decyl alcohol and Butralin on sucker control were $89.6\%\;and\;90.7\%$, respectively at 14 days after application in the variety KF118. But that of sequential application of two chemicals was $81.9\%$ at 30 days after application in the variety KF118 and $86.1\%$ in the variety KB303. Effect of two applications of Yellow ribbon or Butralin was highest in two varieties. The central downward spray showed a little higher control effect than the pouring of two chemicals. There was not significant difference of sucker control effect between forty and fifty times solution of Decyl alcohol in the variety KB303.

N/A The odor problem around sewage and wastewater treatment plants has started to be realized while large-scale public wastewater treatment systems were being built. So all the recently constructed sewage and wastewater treatment plants contain a separate deodorization facility. However, currently deodorization technologies which were already developed and put to practical use to control odors at the treatment plants include physical technologies which adsorb and dilute odor substances and chemical technologies which neutralize, flush, or mask those substances. The main objective of this process, HBR-II, was to develop an oder-free advanced treatment process capable of removing odors and nutrients simultaneously and efficiently in a single sewage and wastewater treatment process using soil origin microorganisms. The results showed that this odor-free advanced treatment process removed 90, 70, and 80% of the influent organics, total nitrogen, and total phosphorus, respectively. At the same time, odor causing compounds were also efficiently removed, i.e., 60, 90, and 90% of influent hydrogen sulfide, methymercaptan, and dimethyl sulfide, respectively.

This study was conducted to examine middleㆍhigh school 720 students in seven regions of middleㆍsmall city and town, Myon for 2 months from March 2 through April 30, 2002 in order to realize a side of school health education in middleㆍhigh school and health education need as well as health education specialist in school in the future. The results of this study can be summarized as follows. 1. Health condition is now 'normal' is 51.0%, 'good' is 45.0%, 'not good' is 4.1% and health condition of children is good as much as education level of mother is higher. 2. Experience to learn health education in school for one year recently is 'no' is 39.6%, 'don't know' is 32.6%, 'yes' is 27.8% and it represents health education in school doesn't work well and experience to learn health education is lower and lower in town and Myon. 3. Health education ways to work in school now are 'Movie, Video, Slide' is 40.7%, 'education as groups of nurse-teacher' is 38.6%, 'to distribute health education material and book' is 7.7%, 'education by setting an example' is 3.4%, 'the others' is 9.7%. 4. Time of appropriate health education for one time is 'about a hour' is 56.7%, 'about 30 minute' is 33.8%, 'about two hour' is 7.6%, it represents this situation is because of what students' time is lack and burden about a curriculum in an education administratin and school classed of a focused school score. 5. The average score of satisfaction of health education in school is 16.99±0.58, 'men' is 1.79±0.60, 'women' is 1.61±0.55 as the distinction of sex, satisfaction level of men is higher than women. 6. Learning route about health information is 'through mass media' is 59.9%. 'through family, friend' is 15.0% 'health education lecture' is 7.2%, 'printing media' is 6.1%, 'medical institution' is 5.6%, 'the others' is 5.1%, 'public health center' is 1.0%, 'through mass media' is the highest percent as each 59.1% and 60.6% in all of men and women. 7. The most efficient education way of health education is 'movie, video, slide' is 32.6%, 'health education specialist who works school' is 21.9%, 'school health education by nurse-teacher' is 16.0%, 'way through mass communication' is 11.6%. 8. The appropriate health education specialist in the future is 'health education specialist who has qualifications' is the highest as 64.5%, 'nurse-teacher' is 12.4%, 'medical personnel(doctor, a physician of oriental medicine etc.,)' is 11.0%, 'staff in public health center' is 7.2%, people in other regions(health and medical professor etc.,) is 7.0%, it represents school health education is not actual and is formal now in second hand. 9. The most necessary health education program is 'program of stress solution' is the highest as 24.9%, 'program of no smoking' is 22.7%, 'sexual education program' is 19.8%, 'school violence program' is 8.8%, 'isolate from their friends prevention program' is 8.0%, solution program of stress which gives student by school score was very necessary. Therefore, school health education is formal and inefficient because school education focuses on an entrance exam, so middleㆍhigh school students decrease concern and interest about health education. Furthermore, reliance is gotten down about nurse-teacher who takes charge of school health, a charged person of school health education wants more chargeable health education staff. And a solution program of stress that gives students by school score was very necessary. According to active concern and planned, systematic school health education is necessary to give right health knowledge, health maintenanceㆍpromotion and setting of appropriate health education specialist is very urgent.

박훈,이미경 한국농화학회 1987 Applied Biological Chemistry (Appl Biol Chem) Vol.30 No.2

Relationship between the contents of ginsenosides in root and minerals (N,P,K,Ca,Mg) in leaf and root of and year Panax ginseng grown with solutions of various N,P,K levels was investigated by simple, multiple and partial regressions. In root K,N, and P in decreasing order showed significant negative correlation with each ginsenosides. In leaf K,N, and P in decreasing order showed significant positive, negative and both correlation with root ginsenosides, respectively. Relationship between K and root ginsenosides in the minus K plot did not follow that in other plots. The ratios of K,N, and P, in leaf to root in decreasing order showed positive correlations that were greater than in leaf or root. Mg was negatively while Ca was positively correlated in root but these were reverse in leaf and always non-significant in both parts. Ginsenoside Rd, Re and Rb₁were most affected by mineral contents. The effect of minerals on PT/PD was least.
