The project of desalinization in the new reclaimed land should be executed above all, because the damage of salinity in the paddy fields is due to the excess of salinity. Open ditch one of the most important methods of desalinization for expulsion of salinity by the irrigation water as well as decreasing the ground Water contained salinity. In this research, the effects of open ditch and of desalinization by irrigation water during the period of paddy plants growing, and changes of saline content in reclaimed land which is located in Kang-Hwa-Goon, Kyung-Ki-Do, were investigated. The results obtained in this research are summarized as follows: 1. The depth of saline expulsion by supplying of irrigation water was approximately 30cm to 50cm under the ground surface, but saline expulsion was hardly done in case of the depth which is deeper than the above mentioned, because the moisture and saline content hardly change in such a condition. 2. Infiltration speed of the Horizontal drainage was more rapid than that of vertical drainage in soil of Kang-Hwa reclaimed land. 3. In open ditch, we could make a good condition for the growth of rice plants, because the desalinization was not only rapid but also effective up to the subsoil layer. 4. The reasonable interval of open ditch was about 18m, and we could set limits approximately 30cm to 90cm in the depth of open ditch. 5. Saline changes of the soil in the reclaimed land was sensitive to weather condition and discharge of irrigation water, and changes of the monthly saline content was extreme in case of drying seasons and non-supplying of irrigation water, and saline content of surface layer seemed to be higher than that of subsoil. 6. The saline content of soil and the rate of disalinization showed a tendency to decrease according to cultivating years of rice plants. Rice plants was not nipped by salinity after 3 years cultivating in the conditin of open ditch by 18m iterval on the new reclaimed land.

From September 2, 1995 through October 31, this questionnaire was made by the 1,200 industrial workers who work for 15 enterprises of 5 types of business. And it was for helping to devise a policy and to develop a program for industrial workers' health promotion by understanding the consciousness behavior level of industrial workers in our country and the related factors which are under the influence of it and health promotion behavior. The summary and conclusions are as follows. 1. In health promotion score level by related factors, the health diagmosis level score was 7.37(31.9/100) of the perfect score 9, nutrition level score was 7.00(77.8/100), health education behavior level score was 6.00(66.7/100), exercise behavior level score was 6.01(66.8/100), occupational disease knowledge level score was 6.00(66.7/100). 2. Health diagnosis behavior level was significantly high when the age is older, when the occupation term is longer, when the economic status is better. And wjem tje satosfoed degree for vocational aptitude, working environment, and the education contents. 3. Nutrition (dietary habit) status level was high in men, in the age group of 40 over, in the group of having their spouse, in the group of being paid over one million won a month, in the upper economic classes(P<0.001). It was also high in graduates middle school and in daytime workers(P<0.05). 4. Health education behavior level was high in the older ahe hroup, in a single life (separation by death, divouce, separation) and in the longer occupation term(P<0.001). 5. Exercises behavior level was high in men, in the workers who are paid 500∼990 thousand won a month, in the better economic classes(P<0.01). 6. Knowledge level on an occupational disease was high in men, in the older age group, in the group of having a spouse, in the workers who are paid 500∼990 thousand won a month, in group of having a longer occupation term, and in the residents living not in a large city(P<0.01). 7. When health status was higher, health promotion behavior level, health diagnosis (P<0.001), nutrition(P<0.05), health education behavior(P<0.05), exercise behavior (P<0.01)and the knowledge level on an occupation disease was high. 8. The main factors which are under the influence on the degree of practicing healthy life were the level of knowledge and behavior, sex, his/her health status, and the satisfied degree of working environment. These variables could explain it 18.0%. 9. The factors which are under the influence on health promotion behavior and behavior levels were the variables of the satisfied degerr of education contents, sex, health knowledge, economic status, health status, occupation terms, monthly income, working tiredness. These variables could explain it 21.3%. By these results, it is important for industrial workers' health promotion to level up the health diagnosis behavior, dietary habit considering nutrition, behavior on health education, behavior for exercise, and knowledge on an occupational disease. Especially we should develop the proper program considered sex, health status, satisfied degree of working environment and education contents, economic status, eccupation terms, knowledge on health, and behavior level. Because health promotion business gies in gear with productivity promotion.

제주도 연안해역을 중심으로 한 DMS 농도의 관측

강창희,허철구,이강웅,김기현 濟州大學校 基礎科學硏究所 1997 基礎科學硏究 Vol.10 No.1

The concentrations of dimethylsulfide (DMS) were determined using samples collected from a station located at Kosan, Cheju Island during two field campaigns held in December 1996 and January 1997. The atmospheric DMS concentrations measured at 6-hr intervals during the entire campaign periods, after excluding a few extreme values, spanned in the range of 14 to 410 pptv with mean and 1 SD value of 127±94 pptv (N=42). Between two month periods during which the field campaigns were conducted, a notable reduction in DMS levels was observed which was comparable to the dramatic shift in air temperature. A considerable difference was also noted in DMS levels, when data were grouped by day/night basis. The cause of unexpected, high day-to-night DMS ratios is best explained in terms of high efficiency of daytime source processes relative to low efficiency of nighttime sink processes due to the characteristics of the study location. The surface water DMS of the study site, although scarcely measure, also behaved similarly to its atmospheric counterpart with its range from 0.3 to 19 nM (N=11). When correlation analysis was conducted between the atmospheric DMS concentration and other concurrently determined parameters, significant correlations were observed from most basic meteorological parameters such as windspeed, relative humidy, and air temperature. However, the existence of "not-so-strong" correlations between air temperature and DMS concentrations relative to other ones indicated that the effect of temperature on DMS behavior must be reflected in more complicated manners at the study site. The sea-to-air flux of DMS was approximated through an application of the mass-balance flux calculation method of Wylie and de Mora(1996) under the assumption that sink mechanism within the marine boundary layer is in steady-state condition with its counterpart, source mechanism. Based on this estimation method, we reached a conclusion that oceanic DMS emitted from the southwest sea of the Korean Peninsula can amount to approximately 9~36GgSyr-1.

In order to understande the relationship the fourth grade students' stress and environmental noise, the authors surveyed 421 persons and the sound environment of eleven classrooms and their surroundings of five elementary schools in Pusan area. Both questionnaire and 1/3 octave band noise measuriment were administrated. Each sound level at class room (10-minute recess), corridor, classroom (lesson), playground, and gate was highest mostly at 800Hz, appeared to be 71.70.2 dB, 65.78.7dB, 57.57.9dB, 53.91.2 dB, and 53.52.6 dB respectively. Sound levels at frequencies less than 4,000 Hz were in range of 46.7 dB to 71.7dB, while those over 10,000 Hz were background level of 14.3 dB to 39.6 dB.Noise in corridor was higher than play ground and gate, this fact supports that school buildings seemed to bo little affected on environment sound but the sound proof of most classrooms wall was very poor. In order to grasp how sound affects on stress, multiple regression analysis using backward variable elimination method was conducted, and the resulting equation was as follows(R = 0.186, R2 = 0.035, adjusted R2 = 0.027); Stress = 2.221 + 0.459*(study disturbance due to home noise) + 0/607*(home noise) + 0.227*(sound in lesson).

Background: Some cases of QT interval, corrected QT interval (QTc), QT dispersion (QTd) and corrected QT dispersion (QTcd) have been reported in ESRD, but these results are variable and the influence of a hemodialysis is still controversial, In this study, we investigated the effect of hemodialysis on QT and QTc interval and QT and QTc dispersion in patients with ESRD 15 min before and 15 minute after each hemodialysis. Methods: Sixty-seven patients with ESRD (men 33 & women 34) on three-times stable hemodialysis (>3 months) were randomly enrolled. Fifty control subjects with a similar age and normal renal function were enrolled from this hospital. Routine biochemical studies were measured pre- and post dialysis, at the time of the ECG. Plasma Na+, K+, BUN, creatinine, ionized calcium and phosphate were checked. Twelve-lead electrocardiographs were performed at 10㎜/mv and 50㎜/s using a HewIett-Packard Pagewriter 100, before and after a single hemodialysis session.The QT interval was measured from the onset of the QRS complex to the end of the T wave. If the end of the T wave was not clear in a particular lead then it was excluded from analysis. When U waves were present, the end of the T wave was taken as the nadir between the T and U waves. Each QT interval was corrected for heart rate using Bazett's formula (QTc==QT/√(RR)) (ms). The difference between maximal and minimal QT interval duration was defined as QT dispersion (QTd) in each of the 12 leads. Result: This study demonstrates that QT, QTd, QTcd is higher in hemodialysis patients compared with control subjects, and QT and QTd rise postdialysis to levels comparable to those seen acutely following myocardial infarction, when patients are at greatly increased risk of potentially fatal ventricular arrhythmias, Conclusions: QT interval and QT dispersion, markers of risk for arrhythmias and sudden death, are elevated in hemodialysis patients, and rise postdialysis. QT interval and QT dispersion is an easily obtainable, noninvasive, simple, inexpensive, and widely available method of risk stratification in uremic patients receiving chronic dialysis. Additional studies are needed to clarity whether increased postdialysis QT dispersion results in an increased occurrence of arrhythmias.

The purpose of this study is to investigate body composition of Korean juveniles and later adolescences. The subjects were 188male and divided by five groups, each subjects was tested by underwater weight method. and the skin-fold thickness indirect mesuring method and then the body density, % fat, fat and LBM were calculated. 1. The result shows in height a great increase at 12-17 age and a gradual increase at 12-21 age in weight and vital capacity. This period is thought to be most appropriate for a systematic training. 2. The research also shows body density are 1.0666±0.0150g/ml at 12-13 age, 1.0559±0.0094g/ml at 15-17 age, 1.0626±0.0112g/ml at 19-21 age, 1.0604±0.0090g/ml at 23-25 age, 1.0643±0.0095 g/ml at 27-30 age. 3. A % fat is estimated to be 14.35±6.17% at 12-13 age, 18.63±3.83% at 15-17 age, 15.92±4.55% at 19-21 age, 16.78±3.69% at 23-25 age. In the 15-17 age (second group) the high % fat indicates that the amount of physical activites are not great because this time is to be prepared for a college entrance. The low % fat in the 19-21 age (3rd group) indicates that this time is approaching to an adult period and the amount of subcutaneous fat is decreasing; the amount of muscle is increasing; and the physique conditions are completed in this time. 4. A weight in fat shows 6.25±3.92kg at 12-13 age, 10.26±2.40kg at 15-17 age. 9.91±3.94kg at 19-21 age, 10.96±2.65kg at 23-25 age 9.40±2.83k at 27-30 age. From 15-17 age, the amount of fat is approaching to the steady state level because this time is included in adolescent phase which the amount of subcutaneous fat is decreasing and the amount of muscle is increasing. 5. The amount of LBM is 35.43±5.51kg at 12-13 age, 44.60±4.05kg at 15-17 age, 50.98±5.68kg at 19-21 age, 51.97±5.55kg at 23-25 age, 51.88±4.81kg at 27-30 age with relation to the sport, it is desirable to learn motor skill and systematic process because the muscle development is completed during this time centering the age level of 19-21.

To provide the basic data for improving of curative measures in oriental medicine and for developing of health education and preventive program after understanding of classification of diseases in oriental medicine users, questionnaire interview was carried out with city dwellers, over 20 years old, selected randomly in big cities from 2nd Oct. to 11th Nov. 1995. The results were summarried as follows: 1. In the general characteristics of subjects, the highest portion of each part was 61.2% of female, 25.5% of thirties, 28.5% of high school graduate, 63.3% of middle class and 11.8% of lower class in economic status. 31.9% was housewife, 73.5% was merried and 55.1%, 38.1% came from big or small cities each. 2. By 21 classification of diseases, 19.7% was blood disorders, 17.6% was pregnancy & delivery complications and 15.2% was endorine & nutritional disorders. 3. As for age 22.6% of endocrine & nutritional disorders in twenties, 20.8%, 28.1%, 27.8% of blood & defence mechanism disorders in thirties, forties, sixties each and 24.9% of pregnancy & delivery complications in fifties were the higher than the other groups. 4. By educational level, 47.8%, 30.5% of blood & defence mechanism disorders in uneducated and middle school graduate were the higher than the other groups. 5. As for occupation, 20.8%, 32.9% of blood & defence mechanism disorders in housewives and sales each, were the higher than the other groups. 6. By economic status, 20.2% of blood & defence mechanism disorders in middle and high class, were the higher than the other groups. 7. By marital status, 21.3% of endocrine & nutritional disorders in singles, 22.0%, 25.7% of blood disorders in having partners, were the higher than the other groups. 8. As for living areas, 18.2% of pregnancy & delivery complications in big city dwellers, 21.3% of endocrine & nutritional disorders in town dwellers were the higher than the other groups. The distribution of diseases in oriental medicine users wes very different by chracteristics according the results. So It's important and essential project to improve curative technics and to develop.
