최근에 홀수인 소수 p, n=4k, 그리고 d=((p<SUP>2k</SUP>+1)/2²에 대해서 Seo, Kim, No, Shin<SUP>[1]</SUP>이 m-sequence와 d로 decimation한 부분 수열들 사이의 상관 분포를 유도하였다. 하지만 이러한 상관 분포로부터 수열군이 자명하게 결정되지는 않는다. 본 논문에서는 우선 위의 상관 특성을 유지하는 수열군을 선택하는 방법을 제시한다. 더 나아가서 이 수열군과 동일한 상관 특성을 가지면서도 더 큰 선형 복잡도를 갖는 수열군을 새롭게 생성할 것이다. 끝으로 3진 수열의 선형 복잡도를 특정 경우에 대해서 유도하고 이 경우 원래의 수열군보다 더 큰 선형 복잡도를 가짐을 보일 것이다. For an odd prime p, n=4k, and d=((p<SUP>2k</SUP>+1)/2², Seo, Kim, No, and Shin<SUP>[1]</SUP> derived the correlation distribution of p-ary m-sequence of period pⁿ-1 and its decimated sequences by d. In this paper, two new families of p-ary sequences with family size p<SUP>2k</SUP> and maximum correlation magnitude 2√pⁿ-1 are constructed. The linear complexity of new p-ary sequences in the families are derived in the some cases and the upper and lower bounds of their linear complexity for general cases are presented.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

In this work, effects of total draw ratio change on the mechanical properties of polyester fibers were studied. The process parameter was a total draw ratio and the draw ratios that were used ranged from 6.6 to 7.0. Tensile properties are determined from the tensile tester, and crystallite parameters from the density measurement and X-ray diffraction were discussed with the different total draw ratios. The tenacity, young's modulus and crystallinity were increased to 10.6 g/d, 123.2 g/d and 42.1%, respectively, with increase in the total draw ratio. The relations between total draw ratio and mechanical properties of high tenacity polyester fiber were discussed.

現代生活에 있어서 Recreation의 機能(Ⅱ)

申英植 淑明女子大學校 1978 論文集 Vol.18 No.-

Ⅰ. Perface Now poor, prevailed over the difficult being we put up well living frame and foundation and we could have time to spare and leisure in reserve. But according to this, of course, lack of recognition and knowing about leisure or sports as well as readiness according to leisure or recreation is not putting up. Education is to make higher a nature of mankind. Unless we learned, we could not bearing the man corresponding to new organization. As the planning for the corresponding to the future society, we newly had to recognize the value of a recognition. So we are going to consider about leisure and the role of function and the value of the recreation in this subject. Ⅱ. Modern Living and Recreation ① Characteristic of modern living ② Characteristic of modern living and individual unification ③ Happing of particular strain ④ Labor, play and recreation ⑤ Improvement of human relation and recreation ⑥ Conversion from industrialism to humanism Ⅲ. Psychological result of recreation ① Mental constancy and recreation ② Sincere living and recreation ③ Desiring for various forms and recreation ④ Forming personalty, and recreation Ⅳ. Developing Foundation of Recreation ① Developing foundation of recreation ② Educational progress ③ The reduction of working hours Ⅴ. The problem of present Recreation ① Evading character ② Individualistic tendency ③ Disunion of labor and leisure ④ (conclusion) Groping silution We have described the problem of modern recreation in relation to modern society and the mortal, but if we'll Summarize, the modern leisure can not be made good use as much as expectation. Since the modern society doesn't disply efficient function such as recovery of humanity, exhibition of creation, and reproduction. The causes are a fault of recreational education, public effort, lack of co-operation, labor, and human isolation, etc. In other words modern problem can be solved by improvement of human conditions in labor. As to the first way of improvement, labor itself must reform. We must persuit a plsure of labor in free creative activity. The second, we ourselves need effort to make us delightful. After we consider the reasons why people had to do like that, why people shall do that, and why people follow the way of some another people's living, we must seek for creative pleasure. Therefore an expanding of recreation related to real life and adding function to forming humanity can be expected. The third, for an example, we can say upbringing of new recreation. To do so, plesure of creation as not over activity in itself, but making neigbourhood, co-workers friends, groups, and formative education are necessary Of couse, recrestion as to effort is ideal pleasure which is pursuitted individually, and formation of co-worker in relation to recreation is owing to exhibit function as a breakwater of mass-society, Up-to-date different kinds of camp education is stated to extend actively, This is also a situation as a need of the mor-tal wants. For example, it says that different kinds of camp activity describes the one side of recreation and leisure activity.

오르니틴-아스파테이트의 용해도와 drowning-out결정화에 관한 연구를 수행하였다. 오르니틴-아스파테이트 용액에 알코올을 첨가하면 오르니틴-아스파테이트의 용해도가 극적으로 감소하며, 결과적으로 오르니틴-아스파테이트의 침전이 일어난다. 오르니틴-아스파테이트 침전공정에서 오르니틴-아스파테이트의 회수율과 결정크기는 주입속도, 교반속도 및 주입방식에 크게 영향을 받았다. 또한, 물과 알코올의 혼합액에서 오르니틴-아스파테이트의 용해도는 알코올 분율이 증가함에 따라 감소하는 것으로 나타났다. 알코올-물 혼합용액에서 오르니틴-아스파테이트의 용해도는 Cohn식과 Wilson식들에 의해 성공적으로 예측될 수 있다. Study on solubility and drowning-out crystallization of ornithine-aspartate was carried out. Addition of alcohol to ornithine-aspartate solution reduces dramatically the solubility of ornithine-aspartate and results in the precipitation of ornithine-aspartate. In the process of ornithine-aspartate precipitation the recovery and crystal size of the ornithine-aspartate were significantly affected by the feeding rate , agitation rate and feeding mode. In water and alcohol mixture, the solubility of ornithirne-aspartate was also presented to be reduced as increasing alcohol fraction. The solubility of ornithine-aspartate in solution of alcohol-water mixture can be successfully predicted by Cohn and Wilson equations.
