This study was carried out to investigate the effects of nitrogen rate on major agronomic characters and feeding value of sorghum x sudangrass hybrid on volcanic ash soil of Cheju-do. Application rates of nitrogen were 0, 10, 15, 20, 25, 30 and 35㎏/10a. The results obtained are summarized as follows: 1. Plant height, leaf length, leaf width, leaf number, stem diameter, internode length increased as nitrogen rate was increased from 0 to 30㎏/10 a, but slightly decreased at 35㎏ N/10a compared to control treatment (0㎏/10a). 2. Fresh forage yield per 10a and fresh weight of leaves and stem per plant were greatest at 30㎏ N/10a and decreased with decreasing nitrogen rate. 3. Heading of sudan grass hybrid was earliest at 30, 35㎏ N/10a and delayed at intervels of 2∼3 days with decreasing nitrogen every 5㎏/10a. 4. Crude fat and crude protein significantly increased but crude ash and nitrogen free extract decreased as nitrogen rate was increased from 0 to 35㎏/10a. Crude fiber response to nitrogen rate was variable. 5. The were highly positive correlations between fresh forage yield and plant height, leaf length, fresh weight of leaves, stem and panicle, crude protein, but negative correlation between fresh forage yield and crude ash.

ABSTRACT This study was accomplished to look into the response of main growth characters, yield and chemical composition of Cheju local cowpea on Cheju Island based on the difference between seeding rate. The study took place between May and September, 1998. Number, of days to flowering tended to be delayed as the seeding rate increased. Plant length was the longest at 6kg/10a treatment and the next one was at 5kg/10a treatment. The shortest came from 2kg/10a treatment, 275 cm, 271 and 220cm respectively. Number of branchs and stem diameter became weaker as the seeding rate increased. Fresh forage yields per lOa was the heaviest which weighed 6,073kg at 6kg/10a treatment and 5,840kg at 5kg/10a treatment respectively. The rest decreased gradually. Dry matter yields per lOa, crude protein yields per lOa and total digestible nutrient yields per lOa showed a similar tendency to fresh yields per lOa. The percentage of crude protein and crude fat got higher as the seeding rate increased, but the percentage of crude ash and crude fiber rather tended to decrease. Nitrogen free extract and total digestible nutrient percentages were similar to the change of crude protein percentage. SPAD reading values were the highest at 6kg/10a and 5kg/10a treatment.

ABSTRCT Four rape cultivars were grown at 1 to 5 plants per hill to investigate the effects of the number of plants per hill on major agronomic characters of forage rape in Cheju volcanic soil. Days to flowering of Sparta was 191 days, those of Ramon and Youngsanyuchae were 189 and 188 days, respectively. And that of Hallayuchae was 180.3 days. Days to flowering decreased as number of plants per hill was increased. Sparta was tallest (153.6cm), while Hallayuchae was shortest (131.8cm). Plant height with three plants per hill( 155.3cm) was longest, while with 5 plants per hill(131.8cm) was shortest. The number of branches, stem diameter, leaf length and leaf width gradually decreased as the number of plants per hill were increased. Sparta had the greatest fresh and dry matter, total digestible nutrient (TDN) and crude protein yields, while Hallayuchae had the least. Fresh yield were greatest (7,544 kg) at the three plants per hill. Dry matter TDN, and crude protein yields were also greatest (7,544 kg) at the three plants per hill. Ramon had the greatist SPAD reading (44.7) while Youngsanyuchae had the lowest (40.7). SPAD reading were highest (44,1) in the one plant per hill plot but decreased as the number of plants per plant was increased. Sparta had greater contents of crude fiber and crude ash, but Hallayuchae and Youngsanyuchae had lower contents. The content of crude protein, crude fat, nitrogen free extract(NFE) and TDN were increased as number of plant per hill were increased. But the contents of crude fiber and crude ash were decreased as the number of plants per hill was increased.

버섯 갈변병 유발세균인 P. tolaasii에 길항성을 가진 P. fluorescens의 대량배양을 위하여 배지조성 및 배양의 최적조건을 확립하였다. 세포성장에 있어서 carbon 및 energy source인 glucose의 경우 30g/l일 때 세포농도가 가장 높았으며, yeast extract의 최적농도는 10g/l였다. 또한 균체의 구조합성에 있어 중요한 nitrogen source인 NH_(4)Cl과 (NH_(4))_(2)SO_(4)는 각각 1.0g/l와 0.1g/l일 때 세포성장이 가장 좋은 것으로 나타났고, sulfur source인 MgSO_(4)·7H_(2)O의 최적농도는 1.0g/l였다. 그리고 KH_(2)PO_(2)와 CaCl는 각각 1.0g/l와 0.1g/l일때 세포농도가 가장 좋았고, 온도 30℃, pH 6.0 그리고 초기 D.O가 68일 때 세포성장이 가장 높았으며, 균체 비증식속도(μ)와 생산성(P)도 높았다. P. fluorescens was studied in both batch and continuous culture in order to find out optimum conditions for cultivation. p. fluorescens is an aerobic bacteria and antagonistic to p. tolaasii which causes blotch disease on the mushroom cap. Cells of P. fluorescens were grown well on medium containing 30 g/ℓof glucose, whereas the growth was inhibited with the glucose concentration at higher than 30g/ℓ. The highest values of specific growth rate and productivities were obtained when using 10 g/ℓ of yease extract. Optimum concentrations of NH_(4)Cl and (NH_(4))_(2)SO_(4) for culture were found to be l.0g/ℓ and 0.1 g/ℓrespectively. The culture of MgS0_(4)·7H_(2)O was mostly about l.0g/ℓ as a sulfur source. It was also found that the cell concentrations were at the maximum level when grown on the medium containing l.0g/ℓ of KH_(2)PO_(4) and 0.lg/ℓ of CaCl_(2). Also, the optimum culture conditions were 30℃ and pH 6.0. Cultivation of P. fluorescens at high initial D.O value led to a decrease of bacterial productivity in batch culture. Maximum productivity was achieved at 68 for the initial D.O. value.

The purpose of this study was to investigate the health behaviors and affecting factors on the job satisfaction of pharmacists working at community pharmacy and hospital pharmacy. Subjects served for this study consisted of 1,180 pharmacists including 844 pharmacists working at community pharmacy and 336 hospital pharmacists. Data were collected through questionnaire survey for 4 months from 1st May to 31st August in the year 1998. The results were as follows: (1) The general characteristics among the subjects showed that the pharmacists working at community pharmacy were predominantly more male(M : F ratio = 54.1 : 45.9), higher age, and higher married status than hospital pharmacists who are predominantly more female(M : F ratio = 9.2 : 90.8). Also the pharmacists working at community pharmacy described that they have more concerns on their own health status, exercises and drug medications for healthy life, but showed higher frequency of smoking and alcohol drinking rather than hospital pharmacists. (2) The job satisfactions of the pharmacists working at community pharmacy were influenced by several factors such as their own healths, family-member, good residential environment, good relationship with their neighborhood, and community activities. On the other hand, the job satisfactions of hospital pharmacists were increased according to higher age, married status, and the longer working career. The comparison of the job satisfactions between two groups showed that hospital pharmacists responded positively to the levels of self-developments, work loads, working times, and incomes, but they were negative to acknowledgements to their job professional levels from others. (3) The positive factors related to job satisfactions among the pharmacists working at community pharmacy were higher incomes, proper work loads, speciality perceived by themselves, the levels of self-developments, and good acknowledgements to their job professional levels from others. But those among hospital pharmacists were the levels of self-developments, work loads, speciality perceived by themselves, working times, and incomes in these orders. (4) The comparison of the correlations between job satisfactions and the factors of two groups showed that in case of the pharmacists working at community pharmacy, the important factors were incomes, the levels of self-developments, work loads, speciality perceived by themselves, etc. in these orders, but in case of hospital pharmacists, those were work loads, the levels of self-developments, working times, acknowledgements to their job professional levels from others and age levels. And incomes was lower-level factor on job satisfactions. (5) Pharmacists who always managed their physical fitness showed the higher levels in job satisfactions than the pharmacists who did not. From the results of this study, it was found that the job satisfactions of the pharmacists working at community pharmacy and hospital pharmacists were influenced by working loads, the levels of self-developments, speciality perceived by themselves and acknowledge-ments to their job professional levels perceived by themselves. And it was recommended that the managing authorities should build up the facilities for physical fitness and welfare facilities for the employee, and offer the employee chance of self-actualization through education and information supply of clinical pharmacy.

The purpose of this study was to investigate the conceptual similarity between attitude and intrinsic motivation. Psychologically diverse concepts have been investigated and reviewed in the field of education as well as physical education in order to understand the learners' perspective in the teaching-learning process, and to know how those concepts are applied to learners' achievement. However, a number of studies for each psychological concept became lack of holistic view for students' learning. although in-depth understanding of each concept has been accomplished. Therefore. this study reviewed the constructs of attitude and intrinsic motivation, since these two concepts have been indicated in many educational studies as the most powerful psychological factors conducive to learners' academic achievement in physical education as well as in the other subjects. In this study, it was revealed through review of various studies that there are conceptual similarities between these two concepts. Thus, the relationship between these two of academic specification in physical education, but to be understood an attempt to integrate diverse psychological concepts for the purpose of learners' achievement in physical education.

Oryoungsan which first recorded in Sanghanron, the clinical medical book consists of treating acute febrile disease according to its change, is one of the frequently used oriental medicines. these days, it has been prescribed in symptoms accompanied by edema mostly. therefore it is easy to consider it as a type of diuretics. In Sanghanron it was originally used in the symptoms of perspiration, decreased urine volume, thirsty, flatulence, these symptoms indicate loss of body fluid and the prescription which orders "taking warm water sufficiently" supports this. On this background, it is supposed that Oryoungsan treats dehydration after providing water and electrolytes. To consider that herbal medicines consisted of Oryoungsan make electrolytes go out of the body, The healing mechanism of dehydration doesn't meet this. Because Oryoungsan was used in condition of fever or in similar condition, it is more resonable to understand that restoration of increasing blood flow to the subcutaneous venous plexus regulating body temperature in febrile condition into body circulation, resulting into maintaining main blood volume and into treating decreased urine volume and thirsty is Oryoungsan's function in the dehydration or febrile condition. That is, symptoms are decreased or disappeared through restoring unbalance of internal body fluid. The other target is pain controls, especially chronic headache, facial pain and trigeminal neuralgia, it is suggested that the funciton of pain control of Oryoungsan is related to 5-HT(5-hydroxytrypamine), nerve transmitter in the endogenous analgesic system. Moreover it is also suggested that Oryoungsan is relate to 5-HT, considering the fact that gastroparesis, a symptom of cyclic vomiting syndrome treated with 5-HTID receptor agonist is similar to the 'bi(??)', symptoms appeared in the Oryoungsan-related disease.

ABSTRACT Four cultivars of rape were grown at 5 planting densities in Cheju volcanic soil to investigate the effects of planting density on major agronomic characters of forage rape. Hallayuchae flowered earliest (180 days) while Sparta latest(191 days). Days to flowering was reduced as planting density was decreased. The average plant height of Sparta was 162.2cm and that of Ramon and Youngsanyuchae was 158.4 and 138.6cm, respectively. In 10 X 10cm planting density plot, plant height was 152.5cm and it was gradually decreased as planting density was decreased. The number of branches, stem diameter, leaf length and leaf width of Ramon was greatest, while those of Hallayuchae were least. These variables were increased as planting density was decreased. Fresh forage yield (5,719kg/10a) and dry matter yield (1,229kg/10a) for lOxlOcm planting density plot, were greatest, but those were gradually decreased as planting density was decreased and those for 30 X 30cm planting density plot were 4,232kg/10a and 906kg/10a respectively. Crude protein yield and total digestable nutrient (TDN) per lOa was positively correlated with fresh forage yield and dry matter yield. Sparta produced the greatest fresh forage, and Hallayuchae produced the smallest. Sparta had the highest SPAD reading value, and Hallayuchae had the lowest. SPAD reading was reduced in proportion to increased planting density. Sparta had greater crude protein yield, and crude fat, nitrogen free extract (NFE) and TDN contents and Youngsanyuchae and Hallayuchae had lower contents while Youngsanyuchae and Hallayuchae had greater crude fiber and crude ash contents and Sparta had lower contents. Crude protein yield, and crude fat. NFE and TDN contents were decreased as planting density was decreased, while crude fiber and crude ash contents were increased as planting density was decreased.

We have investigated physicochemical characteristics and behavior of chlorpyrifos(CPF) in the agricultural soil, soil + dry waste food(DWF) and soil +manure. Experiments were accomplished biological degradation of samples loaded with chlorpyrifos in incubator at 27℃ during 30days in laboratory. In this study, Sample containing soil + manure has shown to be better biological degradation than sample of soil + DWF. The kinetics of chlorpyrifos oxidation catalyzed by agricultural soil, soil + DWF, and soil + manure can be described by Henri-Michaelis-Menten equation, V=(Vmax)/( Km+ C), where Vmax is the maximum velocity and Km the concentration of the substrate(C) corresponding to an initial(V) half of Vmax. The value of Vmax and km is 0.0588㎍CPF/g.soil.hr and 7.3529㎍CPF/g.soil in agricultural soil, 0.0601㎍CPF/g.soil∙hr and 4.4117㎍CPF/g.soil in the soil loaded DWF and 0.0890㎍CPF/g.soil∙hr and 4.2818㎍CPF/g.soil in the soil added manure. Therefore the order of Vmax. were Manure> DWF> Agricultural soil.
