Three-dimensional sound is a technique for generating or recreating sounds so they are perceived as emanating from locations in a three-dimensional space. Three dimensional sound has the potential of increasing the feeling of realism in music or movie soundtracks. Three-dimensional sound effects depend on psychoacoustic spectral and phase cues being presented in a reproduced signal. In this paper we propose an effective algorithm for the sound image expansion in television system using stereo image enhancement techniques. In this algorithm, a lower frequency band sound is expanded by phase control and a higher frequency band sound is expanded by cross-talk cancelation. Compared to the other techniques of three-dimensional sound, the proposed algorithm use only two speakers to enhance the sound image expansion, while maintaining the original sound characteristics.

The purpose of this research was to evaluate and to examine the substitutional feasibility of paper sludge extender instead of wheat flour. As the extending materials, taro flour, paper sludge, wood flour and wheat were selected and dried at 103±2℃ during 24 hours in the drying oven and pulverized into three levels(-50∼+100, -100∼+200, -200∼mesh). The extenders were mixed with urea formaldehyde resin in the ratio of 10, 20 and 30%. After plywoods were manufactured by the above extended ratios, dry and wet shear strength were examined. The results obtained at this research were summarized as follows : 1) In 10% extionsion on -50∼+100 mesh particle size, paper sludge showed the highest dry and wet shear strength among the extenders. 2) As 20% extension, wheat showed the highest value. 3) the shear strength was affected by the particle size and extending ratios, and the shear strength extended by paper sludge powder was sensitively varied with particle sizes and extending ratios. 4) The shear strength extended by taro and wheat flour were less affected by the particle size of extender. Therefore, the particle size of extender would be considered along the extention ratios and extender types.

1. Problems Our people and nation are in serious ordeal and also aur concentration of attention and effort to overcome the ordeal are, we can say, very praisable. The violent changes in the aspects of politics, culture, society and economy are at last exposed of the danger of loss of our values. In such changing social phenomena, we with no exception are all experiencing the morbidness caused by them. It is exactly the Yu-Shin (Revitalizing Reform in 1971) and Saemaul(New Community Movement) that supplied and showed the direction of nation-state as r revolution in climate of unestablishment of new values with loss of old ones. It can be true tht we have reaped great fruits in political, economic, social and cultural fields in such hard environments. Then it is very useful project not only in academic and policy-reponse fields, but also in education areas that we try to survey and analyze the Juvenile's response to the national mevements and the changes of concious-structures. 2. Purposes The purposes of the study are: ① to grasp the reality of the Juveniles' view of value by sex, region, age etc., ② to review their responses to government's achievements, policy and its direction, ③ and to diagnose their approach to desirable view of values and degree of achievement. We belive in that concious-reality whcih we can find in process the study will be very important materials to education-policy. 3. Study-methods ① We did survey and analysis of juvenile's veiw of values. ② We set the juveniles of whole nation as the mother group, however, excluding bipolar ones such as Seoulities and the juveniles living in islands and remote hamlet, finally selected the objects of three regions such as Kyeong sang, Chung Cheong and Cheol Ra regions and compared them by various dimensions. Except for detail-survey of Kyung Buk province, we set the objects of students of 3rd grade of sr. high school, professional school (Jr. College) and college in other regions, and surveyed subregionally by large city, medium size city and ruralfishing villages, and by sex. ③ Total number of the surveyed is 3,229 and by regionally, they are 1,725 in Kyung Sang, 616 in chung cheong and 888 in Cheol Ra. ④ The questionairs are handed directly by surveyers and colloected on the spot as soon as they are filled out. ⑤ The view of value by social strata and response degree to policy are tested by %² including the differences among regions, sexes, ages and ect., and to the question required quantitative evaluation, we gave +10, +5, 0, -5, -10 pionts as consent-dissent continuum and calculated the mean number and to other questions, the responses were shown by %. 4. the Juvenile's social and collective life ① Social and collective life of the Juvenile is relatively good in social-conciousness. The view or moral-order was shown 5.31 of f(R)/N. Generally juveniles are answered "waiting for one's turn" in the line at the station of public transit. Girls are shown to be a little better-observer in public order than boys, and teenagers better than the twenties. The view on law-abiding is shown 3.97 of f(R)/N and generally in case of minor offence, they expressed around "be shame". Criminal conciousness is getting stronger from large city to rural and fishing village. There are great differences between the two. Girls are stronger in the conciousness than boys and teenagers stronger than twenties. It is particularly a problem that twenties' f(R)/N is less than 1.72 and theyt are inclining to "may commit so". To the degree of success in the Reform of General Administrative Affairs by our government, f(R)/N is shown 4.94, responding generally "there are a bit fruitful". To the question, degree of recognition is getting stronger to rural-fishing village. Male is stronger than female and teenagers stronger than twenties. And in the hot-bed of corruption, enterprises and tax office are shown 29.63%, and politician 23.27%. General administrative office, judicial and police offices are high in distrust in rural-fishing villages, and tax office, enterprises and politician are getting higher in distrust to larger cities, however, educational institutions are high of trust in medium-size city. Judicial office, enterprises, tax-office, education instution and politician are in high ofdistrust by female, and general administrative office is in high of distrust by male. Teenagers are in side distrust in judicial, police, enterprise and education institutions, and twenties are in side of distrust in general administration and politician. And degree of trust in shamanism is low of 4,76, generally selecting"almost deny", rural-fishing village, female and twenties are higher trust on superstition than large city, male and teenager respectively. The view on national value is shown 2.42. In the village, female, and twenties, cohesion is shown stronger than in city, male and twenties respectively. ② In measurement of juvenile's conciousness on inter-relationship, they are strong in degree of participation of family and community affairs, but in conciousness on collective life, unsatisfactory. They degree of satisfaction in family life is 4.68, generally "in side of satisfaction". It is getting more satisfaction from the villages to large cities. Juveniles in the villages seem to be much unsatisfied with their family, and females than males and twenties than teenagers are higher in satisfaction. Participation degree in community affairs is shown 8.00, generally close to "active participation". Villager than city-dweller and teenagers than twenties are higher in conciousness of participation. The degree of non-alienation from collective life is 2.71 showing the response of "relativelly no particular alienation" and "so on so" generally. Villager than citizen, male than female and twenties than teenagers are higher in alienation. The degree of acception of individual idea in collective life is shown 1.81, close to "so on so". Male's unsatisfaction is higher a little. Their preferable occupations are in priority of production enterprises(28.73%), public service(26.32%) and agriculture-forestry(19.23%). The popular occupations are agriculture-forestry and public service in rural-fishing villages, production-enterprises in medium -size cities and commerce-industry in large cities. Males are favorable to take agriculture-forestry, production and free enterprise and females are to bublic servidce. For teenager, agriculture-forestry and public service are high in priority and for twenties other areas of occupation are high. ③ In conciousness on traditional culture and identity, they are supporting the thought of "loyalty and filial piety", showing 5.36 and generally selected "It is great view on social order though required a lot of revision". females and teenagers are more active on the though required a lot of revision". Females and teenagers are more active on the thought than males and twenties respectively. The capability of foreign affairs in aspects of independent diplomacy was measured to 2.25 barely approaching to "be seen independent efforts". Trust was seen in females, teenagers and the villagers. In cultural conciousness, national superiority was shown very apparently as 28.67%. ④ In aspects of democratic and national conciousness, they showed the degree of satisfaction at democratic society. It was measured through the fruits of Yu-Shin Reform and resulted in 2.17, responding better in females, teenagers and the rural than in males, tweenties and the urban. On 6 years of current term of congressmen, 45.46% responded on "too long", 38.24% on "ordinary" while in rural-fishing villages, they showed high support of 48.90% selecting"appropriate". Many urbans are on "too long" (49.51% in large cities and 49.62% in medium). 44.04% out of females showed the response of "appropriate" while 47.22% of males did that of "too long". 44.43% of teenagers responded "appropriate" while 53.13% of twenties did "too long". National conciousness measured through "degree of confident explanation on national flag" was shown 2.87, responding "can explain to a certain extent" and "can explain" as medium quantity. The villagers, males and teenagers are shown high confidence of it. To the present big increase in national power, juveniles resopnded high motive of "people's self-conciousness" and "great leader" while female showed relatively hgh response on "New Community Movenment" and "Result of education" and so on. teenagers showed "great leader" and twenties did "Result of Education". The view of ideal nation measured through "approach to welfare state" showed 3.87, close to "be seen the effort for welfrare state". The villager, female and teenager showed high response to the positive side. as the way of education how to plant Korean Democracyh among the people they replied "Explaining Korean particular environments" is most useful as 41.40%. Juveniles in medium-size cities, males and twenties showed mainly the above answer. The patriotic attitudes measured through participation of nationa defense showed 8.47, responding close to "participate battle immediately". It can be said very active response that significant number of females selected the attitudes of "support in rear theater". The villagers, males and teenagers are strong in loyalty. If we consider females' particularity, we cannot say they are weaker in loyalty. However it is very considerable that there are responses of "may decide on the scene then", "immigrate abroad" and "negociate with enemy and live together though a few. We are sure that our goverment be required educate and enlighten them immediately. 5. Juvenile's view of Security and National Unification ① Through the measurement of conciousness on communism the surveyer saw that critical ability and attitudes of it is the nearest short cut to anti-communism a key to victory over it. In this dimension, the surveyer analyzed sources of knowledge from masscom 971.47%) and exposed the weak points on lectures and those on government's activities of public information, while rising of masscom's importance. The comparison of South-North living standards showed that 51.34% responded "South Korea is much superior" and 35.08% "superior". Then total 87% of juveniles are on our superio9rity and the rest (13%) showed "equal" or "don't know". In large cities "superiority" was low in % of males and twenties. The confidence in pursuading North Korean on our democratic society's strong points was shown 73.55% of "be confident". However it is very insufficient in education on communism that out 87% of "Our superiority", some 13% are not confident in pursuasion. 13.47% are shown "will decide on the spot to meet" and 5.85% "need not pursuade". The villager, male and teenager have strong response to the above 7.6% of "national symbols". Legality of national foundation" for the urbans and males and twenties "legitimacy of the country" for villagers, and "national culture" for females and teenagers are shown as the grounds of the legitimacy. ② The conciousness of national security measured through the question on aug. 18 Incident(1976) at Pan Mun Jeom appeared following; the causes of the Incident are shown in order of "domestic unstability of North Korea" 928.92%) "shifting responding dissent, 48.77% are on " a little humiliating" and 21.12% are on "utter humiliating". Only 23% showed satisfaction at the counteraction. They showed youthful active counteraction of purnishment, however, it also may cause some anti-American or uncredibility over United States. By region, sex and age, the re3sponses were diffeent greatly. Juvenile's predictions on the possibility of Sino-Soviet Support in case of total war are following; some 80% calculate psychologically that both China and Russia will surely support North Korea militarily and materially, 45.09%, "material support by both". To the way of spritutal militarization, they responded in order of "introduction of North Kjorean affairs" (29.48%), "explanation of N. K's attitudes"(26.20%), "education on N.K's strategy to the South"(20.50%), "to criticize communist thory"(17.96%) and so on. Different responses among regions, sexs and ages are apparent. The Juvenile's pride to foreigner is shown 0.92% of f(R)/N, a little higher to "equality". Villagers are relatively high, medium-size urbans are lowest, and females and teenagers are high in pride to foreigners. ③ To the question on Unification time as one of the conciousnesses of Unification, they responded in order of "impossible forever" (40.16%), "in 30 years"(23.59%) and "in 10 years" (17.99%). It is very undesirable that possibility of Unification is renounced gradually among juveniles. Juveniles are in deadly need of education and enlightenment on increase of Unification conciousness. Differences among the given variable are very apparent. In large city, females and twenties, the re3nunciation is shown greatly. The reasons of Unification are shown in order of "single-nation" (36.38%), "political stability"(32.48%), "preferable to international competition"(20.53%) and so on. Urbans of large cities, males, twenties responded "preferable to Int'l competition", female did "political stability" and teenagers did "single-nation". To "the factors of obstacles to Unification" are shown "antagonistic ideologies" (64.16%), interest situations among Big Four" (18.14%), "North Korean reluctance"(9.60%)and so on. "Interest Situation among Big Four" is shown in large cities and twenties, "N.K's reuctance" in males and teenagers. and "antagonistic ideologies" in females. The ways of Unification are appeared in "economic development"(46.67%). "South-North Dialogue" (26.72%) and so on. "S.N Dialogue" in the villagers, females and teenagers, "Military March for Unification" in males, and "none available" in twenties are expressed relatively high. 6. Conclusion As mentioned above, social conciousness among juvenile is generally good, however, their alienation may be problematic a bit and capabbilty to foreign countries and national conciousness on democratic society are insufficient. However, defence conciousness is highly praisable. That the main sources on communism appeared to be masscom is required to reconsider. Juvenile's view of superiority in living to the North is very confident attitudes and their demandes of more information on North Korean reality and their attitdes toward S. N. Talk as a way of spiritual strengthening is needed to consider by goverment, and some policy-arrangements must be required. Renunication of Unification possibility as "impossible forever" is terrible and therfore, we need to educate and enlighten them for increase of the condiousness. "Military march for Unification"(11.30%) and "no way available"(3.37%) on Unification are surely problematic. In these re3spects, the education on Unification and anticommunism should be strengthended more. To the idea of "loyalty and filial piety", our juveniles are very positive, but indicated "requring a lot of revisions" Then the idea is required significant study and analysis in order to establish as a new value.
