The Studies were conducted to provide the state of mulberry cultivation and it's development in Banguet province (high land) of Philippines. Philippines initiated the sericulture industry with the technical asistance of Japan in 1974 and established mulberry field and sericultural facilities with technical asistance of Korea in 1990 and 1995. The required average of 100 to 150mm per month is not available during the dry season from December to March. Therefore mulching with grass which is available abundantly in the Philippines should be established to conserve moisture, to control soil erosion, surface ran-off and also to increase the humus content in the soil. In chemical properties of mulberry field, the pH value of soil is 4.7, organic matter 1.6%, and available phosphorus 6ppm. Therefore, all fields should do liming and be applied compost. To improve leaf yield for mulberry planted under partial shade area of pine trees, more pruning of pine tree should be done for good sunshining of mulberry, more liming and compost should be applied to improve acidic soil. To control the leaf roller, DDVP and KAFIL are able to be used. When spraying insecticides to control mulberry insect pests, care should be taken to consider the residual effects of chemicals on the leaf. Leaf should be fed to silkworms only after the leaves are free of any residual effects.
The ultimate goal of total artificial heart is permanent substitute for a failed heart in a patient without any other therapeutic modality. Until now, infection has been the main problem related to the mechanical circulatory support system. The best way to solve this catastrophic complication and to improve the quality of life of TAH patients in terms of tethering must be implantation of TAH totally. The EH-TAH has been developed in NCVC from 1987 for this purpose. The system consists of an energy converter and pumps, which are designed to be placed in abdomen and pericardial space separately for a good anatomical fit. To evaluate the anatomical fit and hemodynamic performance of the EH-TAH, in vivo test was done. General condition of the animal and hemodynamic status had been stable until the TAH stopped on the 11th pumping day. The estimated cardiac output was about 7.7L/min. The values of mean aortic pressure, left and right atrial pressure were 93$\pm$10, 19$\pm$3 and 15$\pm$4 mmHg, respectively. The correlation coefficient between left and right atrial pressure was 0.96, which represents the dynamic function of the interatrial shunt in controlling left-right imbalance of cardiac output. During pumping days, the temperature on the surface of actuator had been maintained at 39.7$\pm$0.4$^{\circ}C$, less than 1$^{\circ}C$ higher than the rectal temperature. The TAH stopped on the 11th day due to mechanical problems. We concluded that the EH-TAH possessed satisfactory basic performance including anatomic fit and hemodynamic adequacy, although there were several mechanical problems to be solved yet.
This study aims to investigate smoking patterns in high school student and to give student smoker effective information. The sample of 250 male highschool students out of two different schools in Tae-Jon was questioned from July 10th to 15th. 1995. In analyzing these date. the statistics shows the realities by means of number of students. The results are summarized into 17 items as follows. Regarding the level of smoking. 140 students out of 250 admit that they have ever smoked. 52.1% of smoking students say that the motivation of beginning smoking is mainly curiosity. The survey shows that 22.9% of smoking students feel very good when smoking. It also shows that 30.0% of smoking students began smoking in the first grade of high school. With regard to the volume of smoking per day. 41.4% of smoking students smoke variably. 42.1% drink when smoking. 15.0% spend more than W 70.000 a month. About the question who knows the fact of their smoking. 51.5% answer that their friends know the fact of their smoking. In regard to the resaltionship between smoking and school per-formance. 18.2% of non smoking students make poor grades as compared with 40% of smoking students. 9.3% of smoking students say that they are satisfied with the school life. but 35.7% of them are not satisfied. Regarding the attitude to smoking teachers. 35% of smoking students state that they are affected by them. 69.3% of smoking students say that they will stop smoking. while the remaining 30.7% say that they will keep smoking. The reason of 63.9% to stop smoking is that smoking is bad for the health. The reason of 46. 5% to keep smoking is the acquired habit of smoking. 97.2% know the fact that the major element of cigarettes is nicotine and it is very harmful to the health. 40.8% recognize the harmful effect of smoking by TV and radio programs. 97.2% know that smoking could cause lung cancer. From the above results. I propose as follows We should make specific plan to keep smoking by simple curiosity from being developed into habitual smoking. We should teach them how harmful smoking is and make them stop smoking by themselves. It is very essential for family members and teachers to give continuous interest since childhood. As the teacher affect the students very much, they should give up smoking first. The incidence of smoking should be identified in each of the middle and high schools. smoking prohibition programs relevant to each school should be developed and implemented. The local community should ban cigarette vending machines. Cigarettes should not be sold to adolescents. By setting every place where adolescents gather including schools nonsmoking area. we should decrease their impulse to smoke. then smoking opportunities. and harmful effects to them caused by passive smoking.
In order to study the changes of pregnancy rates according to the factors, age, season, repeated utilization, synchrony, of recipients (29 holstein heifers, one Korean native heifer and 3 holstein cows) were transfered one embryo (from morulae stage to advanced blastocyst) to each, and the results are as follows ; 1. The effect of age of recipient on pregnancy rate in cows and 18-24months of aged group are 100% and 78%, respectively. Under 14months of aged group recorded the worst, 67%. 2. In winter (Nov.-Jan.) and spring (Feb.-Apr.), the pregnancy rate were better than others 100%, 83%, respectively. In the autumn (Aug.-Oct.), it was only 50%, the worst. 3. Among 31 recipients which were utilized at the first, 25 were pregnanted (80.7%), but in the second utilization after the failure of the first transfering, 2 heifers, none of pregnancy was obtained. 4. Pregnancy rates related to synchronization of estrus between donor and recipients are;-(before donor)12hrs. (100%), -6hrs. (86%), +( after donor)6hrs. (67%), + 12hrs. (79%), and +over 12hrs. (50%), respectively. 5. Differences in the pregnancy rate of the recipients +over 12hrs. were significantly large, so in order to ger good pregnancy rate in embryo transfer, the differences of the synchronization must be reduced inner ${\pm}12hrs$. In general, recipients estrus before donor showed better pregnancy rate than estrus after donor.
This study was carried out to examine the effects of seasonality, age, abnormalities of reproductive tract and the frequency of superovulatory treatments on the superovulatory responses and rate of pregnancy in repeat breeder for embryo transfer. Thirty eight eggs were obtained from 6 donors by flushing the uterine horns and 33 embryos were transfered to 33 recipients. (29 holstein heifers, 3 holstein cows and 1 Korean native heifer). From this study, the following results could be obtained: 1. It seemed that spring (Feb.-Apr.) was the better season than any others to produce good embryos. Rate of pregnancy decreased significantly after August because of low heating rate. 2. Rate of pregnancy in the cows with normal reproductive tract showed much better superovulatory responses (80%) than the cows with abnormal reproductive tract (33%), as expected. 3. 8 years old cows produced higher rater of pregnancy than 4 years old cow (79.3 vs 50), and also in superovulatory responses, 8 years old cows showed slightly better results than 4 years old cow. 4. The number of ovulated eggs and rate of pregnancy in the repeated superovulatory treatment more than once were 41 eggs and 85.7%, and those of the donors treated the first superovulatory treatment were 32 eggs and 68.4%, respectively. 5. These results are showing the possibility that utilizing the repeat breeders as donors in embryo transfer could be able to elevate their economic values.
To isolate and identify degradation products of propanil in solution which propanil concentration was 2000ppm with a certain temperature, degradation products and pathway were investigated every 2 weeks for 12 weeks. Extracted mixture was developed with benzene on TLC plate, and Rf values of isolated DCA and TCAB were 0.65 and 0.94 respectively. At the GC analysis, propanil and its degradation products could seperate at the column temperature $200^{\circ}C$, but in order to more good resolution, the column temperature of DCA and TCAB was $140^{\circ}C$ and $250^{\circ}C$ respectively. Functional group of OCA was determined by IR spectrum $3400cm^{-1}$ and $800cm^{-1}$. Proton peaks of OCA were NMR spectrum $6.7{\delta}$ and $3.7{\delta}$. As the results, the major degradation products of propanil in solution were seperated on TLC plate, and thus identified by the analysis of GC, IR and NMR. Proposed degradation pathway of propanil in solution was from DCA to TCAB.
In this study, hydroxypropyl methylcelluloses (HPMCs) were added to prepare the rice noodle and the effects of water dosage, HPMC content, and viscosity level of HPMC on the noodle-making properties of rice dough were examined. As the water dosage was increased, the rice dough after roller pass became more flat and homogeneous. However, when the water dosage was over a certain range, the rice noodle became more waved. In the test result of various HPMC contents, 3% HPMC addition was turned out to be an optimum condition for the best noodle-making properties of rice dough. As the viscosity level of HPMC decreased, the rice dough after roller pass became inhomogeneous. However, the lowest viscosity level HPMC (PMC 40H) did not show any waved rice noodle at even high water dosage indicating the improved noodle-making properties of rice dough. On the whole, it seems that 56~58% water dosage, 3% HPMC content, and high viscosity HPMC (PMC60U) were the optimum condition for preparation of good rice noodle.

This study examined the improvement of bread quality with Curcula longa and Glycyorrhiza uralensis extract (CGE). When counted, the viable cell number in bread with 5% of CGE dramatically was decreased by about 1 log cycle as compared to that of bread without CGE. With regard to oxidation, the content of malonaldehyde diminished in breads with increasing amounts of CGE. Breads with 1 and 5% of CGE were shown to have the highest antioxidative effect. The moisture contents of bread with CGE and bread without CGE were not much different during the early storage period. After six days of storage, however, the moisture contents of bread without CGE and bread with 0.5% of CGE decreased about 16%. On the other hand, the moisture contents of bread with 1% and 5% of CGE did not change dramatically. Their moisture content was decreased by only 4% during the same storage period. Although color, lightness and redness gradually diminished with increasing amounts of CGE in bread, conversely yellowness increased. In the sensory evaluation, bread with 0.5% and 1% of CGE scored the highest: 3.66 and 3.67 out of 5, respectively. Bread with 5% of CGE scored the lowest of the various bread tested. From these results, the addition of 1% CGE in bread had a good effect on improvement of preservation and development of quality.

The preservative effect of cellophane film packing on the quality of semi-salted and dried mackerel was studied. The product(P) of semi-salted and dried mackerel was prepared from raw mackerel by filleting, cleaning, soaking in 15%9v/w) salt solution for 30min, draining, packing with cellophane film (PT# 300, thickness:$20{\mu}{\textrm}{m}$) and drying for 4 hrs at $40^{\circ}C$ in hot air dryer. The product (C) was also prepared without cellophane film packing after draining. The product (C) and (P) were stored at $5.0{\pm}0.5^{\circ}C$. After processing and during storage, moisture content of product (P) was higher than that of product (C), but contents of VBN(volatile basic nitrogen), amino nitrogen and TMA of product (P) on dry basis were lower than those of product (C). Viable cell count, TBA value, peroxide value and decreasing rate of polyenoic acid of product (P) were also lower than those of product (C). In sensory evaluation, the shelf life of product (C) was about 9 days and that of product (P) was about 14 days. From the results of chemical and sensory evaluation, it was concluded that cellophane film packing was a good condition for preserving the quality of semi-salted and dried mackerel.
This study was performed to investigate about sleep quality and orofacial pain pattern between experimental and control group. 101 subjects with temporomandibular disorders without any psychologic and neurologic problem were selected from the patients presented to Wonkwang University dental hospital. Routine clinical examination for TMD was carried out, especially for the frequency of headache and the craniocervical muscles were also done by the author in the first visit. All the subjects filled out the questionnaires, that was, for the evaluation of sleep quality using Pittsburgh sleep quality index(PSQI), and for the analysis of behavioral pain scale questionnaires. Data obtained were statistically processed by the SPSS Windows program and the results of this study were as follows: 1. Subjective sleep index, sleep latency, sleep disturbance, global score in control group were significantly lower than 2. Subjective sleep index, sleep disturbance, global score in subject with headache were significantly lower than subject without headache(P<0.05). 3. Medicine taker have sleeping drug. Caffeine drinkers was significantly higher in daytime dysfunction, global score than no drinker. 4. It have more frequent head and neck pain, pain spreading, daily life difficult in poor sleeper than good sleeper.
