개인이 기업을 창업한 후 건전한 경영관과 경영이념에 입각하여 지속적인 성장.발전을 이룩하기란 결코 쉬운일이 아니다. 특히 기업의 내부환경과 외부환경은 정확한 예측이 불가능하므로 이를 극복하면서 기회로 인식하기에는 기업들의 자생력이 매우 미약한 실정이다. 최근 고임금, 고물가, 고금리, 고물류비의 4고는 기업을 더욱 어려운 상황으로 이끌고 있다. 그러나 현재 우리나라의 기업이 처해 있는 여건이 불안하다고 하지만 매년 새로운 기업이 창업하여 지역경제 및 국민경제에 일익을 담당하고 있음은 주지의 사실이다. 정부에서도 국내기업의 경쟁력.생산력 약화의 현상을 직시하면서, 일연의 기업의 활성화 방안 및 창업기업(벤처기업 포함)에 대한 범정부적인 지원을 위해 1997년 8월 개통을 목표로 현재 종합기업서비스지원(Inno-NET)시스템 구축을 준비중에 있어, 향후 창업을 희망하는 사람들은 자기가 계획한 사업과 관련된 자료나 정보를 쉽게 수집할 수 있게 되었으며, 과연 어디에서부터 시작을 해야 되는지? 하는 과제를 해결할 수 있게 되었다. 물론 그동안 전혀 창업희망자에게 창업관련 자료나 정보를 제공하는 기관이나 단체가 없었던 것은 아니나 다만, 이를 통합, 일원화하겠다는 것이다.

부정교합과 구강영역의 악습관과의 관계를 구명해 보고자 본 저자는 구내 악습중 비교적 발생빈도가 높으며 부정교합에 미치는 영향이 크다고 생각되는 tongue-thrusting에 대한 다음과 같은 일연의 조사를 시행하였다. 1. Tongue-thrusting의 빈도와 부정교합의 유형과의 관계를 조사하였다. 2. 서울대학교 치과대학 부속병원에 내원한 263명의 부정교합 환자로부터 tongue-thrusting의 유무, 수유방법, 구내악습 및 상기도병변상태를 관찰하였다. 결과는 다음과 같았다. 1. 15세 내실 17세 남학생 1,356명중 tongue-thrusting을 보인 사람은 $12.7\%$였다. 2. Angle씨 3급 불정교합이 tongue-thrust swallowing과 가장 밀접한 관계가 있었다. 3. 인공 수유가 tongue-thrust swallowing의 원인이 된다는 명확한 근거는 없었다. 4. 상기도의 만성 병변은 tongue-thrust swallowing과 무관하였다.

A series of consolidated-undrained cubical triaxial tests was performed to investigate the three- dimensional strength characteristics of anisotropic overconsolidated clay. All specimens sampled in field were loaded under conditions of principal stress directions fixed and aligned with the directions during sampling. A sufficient number of tests It was performed to deter.mine the three- dimensional failure surface in the octahedral plane. The adjusted effective friction angles obtained by the stress state projected on the same octahedral plane did not show anisotropy, while the measured effective friction angles showed considerally difference according to the axes of speccimens. Therefore, Lade failure criterion proposed fort isotropic materials could be also used practically for anisotropic overconsolidated clay. The direction of the plastic strain increment wrectors superimposed on the principal stress space was nearly perpendicular to the traces of the failure surface in the octahedral plane.

Considering the flood problem in urban areas, it is important to estimate disaster risk using accurate numerical analysis for inundation. In this study, it is carried out to calculate inundation depth in Samcheok city which suffered from serious flood damage in 2002. The urban flood model was developed by cording Manning n, elevation, and building's rare on ArcGIS for reducing error on data exchange, and applied for estimating flood damage by grid. This paper describes the extraction of sewer lines and buildings area, estimates its influence on flood inundation extent, and integrated 1D/2D flow to simulate inundation depth in high-density building area. This paper shows an integrated urban flood modeling including rainfall-runoff, inundation simulation, and mathematical flood damage estimation, and will serve drainage design for reducing its damage.

An inulase from Streptomyces chibaensis was purified about 120-fold with the yield of 38 by ethanol precipitation, DEAE-cellulose chromatography and Sephadex G-200 gel-filtration. The purified enzyme showed the maximal activity at pH 6.5 and was fairly stable between pH $5.0{\sim}9.0$ The enzyme was slightly activated by $Mn^{++},\;Mg^{++}\;and\;Co^{++}$, and markedly inactivated by $Hg^{++}\;and\;Ag^{+}$. The inulase was characterized as a typical endo-inulase which hydrolyzed inulin in a random manner and Km for the inulin was $4.54{\times}10^{-4}M$.

An experiment was conducted to evaluate relative biopotency of tri-iodothyronine ($T_3$) and thyroxine ($T_4$) to induce oxygen consumption in young chicks. Four experimental groups of 3 chicks were injected with $T_3$ or $T_4$ at a dose of 500 or 1000mg per kg body weight, and thereafter oxygen consumption was measured by indirect calorimetry using a respiration apparatus. Oxygen consumption was significantly increased at 2 and 4 hour in the $T_3$ or $T_4$ treated chicks at 500mg at 2 hour. From coefficient of a multiple regression equation of oxygen consumption on $T_3$ or $T_4$, it was concluded that $T_3$ was shown to be two to three times as biologically active as $T_4$.

An experiment was conducted to establish the appropriate tranaplanting method of sesame seedlings. Covering of polyethylene film on nursery bed resulted in more adventitious roots and better growth after transplanting. Nursery soil showed the best results when it was mixed with the equal amounts of soil, sand and compost. The most healthy seedlings were raised by spot seeding of 5${\times}$5 cm distance and 4 cm bed-depth. Compared to direct seeding on June 15, sesame seeded on June 10 followed by transplanting on June 30 flowered 4 days earlier and produced more capsules per plant and 18% more seed yields.

Formulation and production performance of proposed high nutriton-low cost (HNLC) supplementary foods for children in Korea were studied for Wonseong County Comprehensive Nutrition Program. The basic formulas recommendable from the experimental results on the nutritional value, organoleptical qualities and mechanical performance using MFM-KIST extrusion cooking system were considered as CSS-3, CSS-4 and BSS-4. Initial priority of application soybean was with CSS-4(68% corn flour, defatted soybean flour 20%, sesame 2%, corn oil 4%, sugar 4%, salt 1%, vitamins, mineral and other additives 1%). All these formulas as on rioted snack type-HNLC supplementary foods were found in the acceptable range of mechanical, organoleptical and economical point of view.

The followings are some results obtained from a series of experiments for the culture of eels from the elver stage in the laboratory from April 1973 to June 1974. 1. The optimum temperature turned out as 30t in the early stage culture. 2. The exponential curve of growth rate for a ten day period at the temperature between $20^{\circ}C$ and $30^{\circ}C$ was represented by the following equation: $$R=0.0056296\;T^{1.80740}$$ 3. The elvers and small eels that were kept improperly for a long time before this experiment also showed the same growth rate, compared with other healthful eels captured directly from the estuarine areas. 4. Those that showed retarded growth among a group of eels during the culture recovered the normal growth rate if graded out and kept in the other aquarium. 5. Feeding rate was not affected when the content of ammonia was less than 5 ppm, but it decreased by half when the content exceeds 6 ppm. 6, The elimination of fecal stuffs and uneaten dispersed feed was very important for the maintaining the water in quality.

The effects of vernalization and darkness on flower initiation were reviewed by using naked barley varieties. The dark effects were pronounced on flower induction even at 25$^{\circ}C$. There were no differences in flowering responses among varieties. The effects of vernalization and darkness combined with 25$^{\circ}C$were 100% and 60% respectively which showed a significant difference. When the alternation of darkness with light was taken as first and last the flowering rate was 92 percent. When it was intercalated by light treatments the flowering rate was 91 per cent. Thus the effects of vernalization and darkness seems to differ.
