This study was conducted 1) to compare the nutrient content and mineral composition of the Philoppine indigenous sheep and goats diets when grazed in common pasture during rainy season, 2) to determine the influence of sampling methods on nutrient content and mineral composition of upland (UP) and lowland (LP) native pastures, and 3) to compare these two pasture types in terms of nutrient and mineral composition. Experiment 1 used sis esophageally fistulated animals, three each for sheep and goats. Weekly extrusa collection was done for a period of three months. Experiment 2 was conducted in UP and LP; these were sampled thrice by three methods, plucking, clipping and use of three esophageally fistulated sheep. Results of Experiment 1 indicated that the diets of sheep were greater in crude protein(CP; p < 0.01) and ether extract(EE; p < 0.05) but lower in crude fiber (CF) and acid detergent lignin (ADL; p < 0.05) than that of goat diets. All other nutrient fractions including mineral composition were not significantly different from each other. Significant findings of Experiment 2 were: CP content of UP was in the order fistulated > plucked > clipped (p < 0.05); CP content of LP was greater (p <0 .05) in fistulated and plucked samples; and ash content was greater (p < 0.05) in fistulated samples of both pastures. The CP of UP was different (p < 0.05) from each sampling method but the CP of LP and ADL of both pastures were greater (p < 0.05) in clipped samples. Most minerals either macro or microminerals were greater in fistulated samples of both pastures. Pooled data of the two pastures showed that LP had better nutrient characteristics and greater mineral composition. Based from this study, there were few differences between the diets of indigenous sheep and goats when grazed in common pasture. Also, sampling methods influenced the nutrient composition of indigenous sheep diets.

The Japanese type combine harvester has adopted rubber crawlers for the driving mechanism from first production . However, combine harvesters with movable track rollers in the rubber crawler system have been adopted recently for the purpose of stability at the time of climbing over the footpaths between rice fields, as the results of the machines becoming large. However, the dynamic characteristics of movable track rollers have not been clarified. For this reason, the design of movable track rollers depends on trial and errors. It is known that vibration characteristics of the vehicle with movable track rollers are different from the vibration characteristics of the vehicles with fixed track rollers even though the track roller arrangements are the same. Therefore, the theoretical analyses of movable track rollers must be hurried in order to formulate a reasonable track roller arrangement design. the authors have studied the vibration characteristics of the rubber crawler ve icle with fixed track rollers. in this study, the dynamic model of the vehicle with movable track roller sis compared with the dynamic model of the vehicle with fixed track rollers. Next, motions are simulated to analyze the movable track rollers by expanding the motion equation which were constructed for the dynamic model of the fixed track rollers.

The purpose of this study was to investigate the relationship among urn leptin, nutritional status, and urn lipids, glucose of 99 middle school girls residing in Kyluggi-do, Korea. Subjects were assigned to one of three groups such as underweight(BMI < 20, n=38), normal(20$\leq$BMI<25, n=36) and over weight(BMI$\geq$25, n=25) groups. The nutritional status of the subjects was evaluated by anthropometric measurements, questionnaires, 24-hr dietary recalls and blood anal),sis. The results were as follows : The mean age, body weight, height and BMI were 13.93 years, 55.19kg, 158.40cm and 21.96kg/㎡ respectively. The mean menarche age of the subjects was 12.64 years and the mean daily energy intake was 94.22% off RDA for Koreans. The energy ratio from carbohydrate fat and protein was 63: 24: 13. Underweight group showed the lowest intakes of oils and fats among three groups(p<0.05). The mean serum levels of leptin, glucose, total cholesterol, HDL-cholesterol. LDL-cholesterol and triglyceride were 10.57ng/ml 78.80mg/dl, 12.29mg/dl, 48.07mg/dl, 93.50mg/dl and 78.61mg/d1, respectively. The mean atherogenic index was 2.37. There were significant increases in serum leptin, glucose, LDL-cholesterol, triglyceride and atherogenic index of subjects with increases in their BMIs. Serum leptin showed a significantly positive correlation with BMI(p<0.001), body fat percent(p<0.001). When BMI was adjused, serum leptin showed a significantly positive partial correlations with intakes of animal protein(p<0.05), milks and animal foods(p<0.05), Serum leptin showed a significantly positive correlation with serum glucose(p<0.05) total cholesterol(p<0.01), LDL-cholesterol(p<0.001), triglyceride(p<0.001) and atherogenic index(p<0.001), however, it had significantly negative correlations with HDL-cholesterol(p<0.05). Therefore, these results suggest that the increase of serum levels of leptin may elevate the risk of cardiovascular disease and lipids and some nutrient intakes may be related with serum leptin levels.

Biepitaxial Y$_1Ba_2Cu_3O_{7-x}$ (YBCO) and La$_{0.2}Sr_{0.8}MnO_3$ (LSMO) thin films have been prepared on SrTiO$_3$ buffer layer and MgO seed layer grown on Al$_2O_3$(11${\bar{2}}$0)substrates by dc-sputtering with hollow cylindrical targets, respectively. We charaterized Josephson properties and significantly large magnetoresistance in YBCO and LSMO films with 45$^{\circ}$ grain boundary junction, respectively. The observed working voltage (I$_cR_n$) at 77 K in grain boundary junction was below 10${\mu}$V, which is typical I$_cR_n$ value of single biepitaxial Josephson junction. The field magnetoresistance ratio (MR) of LSMO grain boundary juncoon at 77K was enhanced to 13%, which it was significant MR value with high magnetic field sensitivity at a low field of 250 Oe. These results indicate that inserting the insulating layer instead of the grain boundary layer with metallic phase can be possible to apply a new SIS Josephson junction and a novel magnetic device using spin-polarized tunneling junction.

The grain morphology, the changes in morphology and Jc with the thermo-mechanical treatment (TMT) history, the field dependence of Jc and the nature of intergranular bonding were studied in $T_{10.8}$$Pb_{.2}$$Bi_{0.2}$$Sr_{1.8}$$Ba_{0.2}$$Ca_{2.2}$$Cu_{3}$$O_{z}$/Ag tapes. As a result, incorporation of intermediate rolling during the final heat-treatment resulted in of plate-like TI-1223 grains, and thus enhanced Jc. Jc's near 2.5$\times$104 A/cm2 at 77 K and 0 T were obtained in just rolled tapes with an excellent reproducibility. The high Jc's seem to grain-connectivity easy recovery of excellent grain-connectivity during final heat-treatment after inter -mediate rolling, probably due to retarded T1 evaporation and excessive Ca content in the present composition. The strong field dependence of Jc even in low fields, however, indicated that there still existed significant weak-links and the degree of directional grain-alignment was far from the desired one. The intergranular binding in the tapes seemed to be mainly dominated by SIS junctions.

The purpose of this study was to defined mothers perception of their infants when the babies were high - risk babies, and to describe the feelings and responses of the mothers following on the birth of high - risk babies and on their hospitalization. The subjects of the study were 30 mothers of high-risk infants at D and M Hospital of E University. Data were collected between August 1993 and June 1994. Using the Neonatal Perception Inventory(NPI ) devised by Broussard to determine the perception of mothers and an open-ended, semi-structured interview which was conducted in the nursery room within 24 to 72 hours after delivery And NPI tested 1 month after the babies were discharged from the NICU also. Data were analyzed using SAS and content analy-sis. The results of this study are as follows ; 1. The mothers tended to perceive their infants positively, regardless of the condition of the infant. Mothers who perceived their infant negatively were slightly increased at 1 month after the babies were discharged from the NICU, but the difference was not statistically significant. 2. Mothers reported that they thought that the newborn can see and hear well, and also they can ex-press themselves. 3. There were many types of response noted such as anxiety, fear, helplessness, pity, resentment, guilt, resignation, hope, relief, appreciation, and feelings of being able to overcome the situation. These were differentiated into positive and negative responses. The finding of positive responses being expressed by mother of high -risk infants while their infants were in NICU was a unique finding especially, appreciation and feelings of being able overcome the situation. The results suggest the need for replication studies and for research on nursing interventions directed at improving the quality of life of high-risk infants and their mother.

이 논문에서는 한국 과학기술정책의 시기별 특성과 전체적 특성을 검토하였다. 과학 기술정책의 발전단계는 형성기, 성장기, 전환기로 구분하였다. 한국에서는 과학기술의 진홍을 위한 제도적 기반이 공업화의 초기 단계부터 갖추어졌고, 1980년대 이후에는 정부연구개발사업이 전개되는 가운데 민간 부문의 기술혁신활동이 급속히 증가했으며, 1990년대 후반에는 과학기술정책에 대한 새로운 이념이 모색되면서 관련 법령 및 계획이 정비되기 시작하였다. 과학기술정책의 전체적 특성은 정책레짐이란 개념을 바탕으로 분석하였다. 지금까지 한국의 과학기술정책은 산업발전을 가장 중요한 정책목표로 삼아왔고, 정책수단의 측면에서는 외형적 투입요소가 증가하는 양상을 보였으며, 관료 중심의 정책문화가 지배적이어서 경제문화, 학문문화, 시민문화는 충분히 발전하지 못했다.

The consumer affair is one of the rapidly evolving problems in the process of recent economic growth. As the society and its economy changes, the nature and the scope of the consumer affairs also changes. while the main concept of the consumer affaires originated from the market mechanism, it is now expanding beyond the market mechanism to include everyday lives of consumers. In solving the problems which arise form the status difference between the manufacturer and the consumer the manufacturer's action is no less important the consumer's self-improvement of its status. The manufactures with the purpose of getting maximum profits from the consumers are conducting the consumer oriented managerial marketing, but this sis done form the manufacturer's point of view with the consumer's position being neglected. It is the purpose of this paper to investigate the nature and direction of the marketing from the consumer's position being neglected. It is the purpose of this paper to investigate the nature and direction of the marketing from the consumer's point of view. For this study a couple of pre-investigations were done. First, I surveyed the changing consumers with economic growth the developing process of marketing, and the cause and characteristics of the today's consumer affaires. Second, I studied the concept change of the modern marketing, and the concept of the consumerism which was materialized by this concept change. I further studied, with the consumer's point of view, the socioecological marketing which is based on the consumerism. The conclusion of this investigation is that the manufacturers should convert the in humanized marketing to the more human and environment conscious socioecological marketing because the consumer affairs which arise from the mass consumption of the modern days are expanding to include everyday's problems. This conversion naturally should be based on the human concept based consumerism. To be more effective, the manufactures should assume more social responsibilities and conduct the socioecological marketing voluntarily and willingly.

We map two molecular clouds located in the exact anticenter region emitting in the (J = 1-0) transition of $^{12}CO$ and $^{13}CO$ using the 3-mm SIS mixer receiver on the 14-m radio telescope at Taeduk Radio Astronomy Observatory. The target clouds with anomalous velocities of $V_{LSR}{\sim}-20km\;s^{-1}$ are distinguished from other clouds in this direction. In addition, they are located in the interarm region between the Orion Arm and the Perseus Arm. Sizes of the clouds are estimated to be about 8.6 and 10.8 pc, respectively. The total mass is estimated to be about $4{\times}10^3$ $M_{\odot}$ using CO luminosity of the clouds. Several cores are detected, but no sign of star formation is found according to the IRAS point sources. Their larger linewidths, anomalous velocities, and their location at the interarm region make these clouds more distinguished, though their physical properties are similar to the dark clouds in the solar neighborhood in terms of mass and size.
