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 Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in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.

신동명,김우식,김용욱 경희대학교 산학협력기술연구원 1997 산학협력기술연구논문집 Vol.3 No.-

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.

『Ilbonseogi』(edited A.D.720) was studied to investigate the medical and pharmaceutical exchange among ancient Korea, China and Japan. It seemed that Korean and Chinese traditional medicine was introduced to Japan through Korea. It was also shown in 『Ilbonseogi』 that Koreans who lived in China and Japan during that time seemed to have active medical idea exchange. From various facts indicated in 『Ilbonseogi』, it was believed that Korean and Chinese traditional medicine was the basis for the foundation of Japanese traditional medicine.

Although there have been many clinical studies about the facial trauma in the recent as well as in the past, severity and frequency of facial trauma are reported multifarious. It seemed to be because of variety of social, cultural, and environmental factors, and the view point of investigators. In this study, we investigated about the patients visiting emergency room during recent 4 years(2004-2007), and compared with retrospective study during former 10 years(1992-1996, 1999-2003) in Dept. OMS Pusan National University Hospital. We assessed the cause, type, demographic, etc, and analyzed alterations of facial bone fractures during past 3 periods. The results were as follows. The total number of patients was increased. 429 patients treated for maxillofacial fractures between January 1992 and December 1996, 466 patients treated between January 1992 and December 1996 and 764 patients treated between January 2004 and December 2007. The male-to-female ratio were 4.6:1, 3.9:1, and 4.16:1, respectively. Patient in the age groups of 10-19 years and 20-29 years increased in the latter two periods. Assaults and falls are decreased gradually, but slip down s are increased. Traffic accidents are still major cause of facial trauma. The mandibular fractures showed the highest incidence thorought three periods. Symphysis fractures of mandible was increased and condyle fractures of mandible was drecreased in the third period.

신주식,김영신 충북대학교 연초연구소 2006 煙草硏究 Vol.20 No.-

본 연구에서는 발아력 향상을 위해 담배품종 Nicotiana tabacum cv. KF109와 cv. KB108 종자에 종자전처리방법 중 하나인 solid matrix priming (SMP)처리를 하여 전처리 효과를 알아보고 전처리과정 중 담배종자 발아시 에너지원으로 사용되는 지방산의 함량 변화를 조사한 결과 아래와 같다. 1. 발아시험결과 전처리에 의한 처리간 발아율 차이는 보이지 않았으나, 발아세, T50은 KF109의 경우 9일처리, KB108의 경우 7일처리에서 가장 높았다. 2. 종자내 지방산을 분석한 결과 처리기간동안 함량의 변화가 큰 지방산의 종류는 palmitic acid, stearic acid, oleic acid+elaidic acid, linoleic acid+linolelaidic acid, α-linole nic acid였다. 3. 지방산 종류에 따라 다소 차이가 있으나 각 지방산의 함량은 KF109의 경우 8일 또는 9일에서, KB108의 경우 6일 또는 7일까지 증가하였다가 이후 감소하였다. 4. 특히 지방산 중 oleic acid+elaidic acid와 linoleic acid+linolelaidic acid 함량의 변화가 가장 컸으며 다른 지방산에 비하여 함량도 높았는데 KF109와 KB108 품종의 경우 8일과 6일처리까지 각각 증가하여 최고에 이른 후 급격히 감소하는 결과를 보여 종자전처리 진행과정을 확인하는 데에 이용 가능할 것으로 판단된다. We studied the effect of SMP(solid matrix priming) treatment, a pretreatment for germination enhancement, to tobacco seeds by measuring of germination rate and fatty acid, energy source for tobacco germination. The results were as follows. In result of germination test, germinative ability was the highest in KF109 at nine day treatment and in KB108 at seven day treatment. The composition of fatty acid in tobacco seed confirmed by gas chromatography were palmitic acid, stearic acid, oleic acid+elaidic acid, linoleic acid+linolelaidic acid, and a-linolenic acid. Palmitic acid, stearic acid, oleic acid and elaidic acid, and linoleic acid and linolelaidic acid were highest in KF109 at eight or nine day treatment and in KB108 at six or seven day treatment. Especially, content of oleic acid + elaidic acid, and linoleic acid+linolelaidic acid were changed largely by treatment, so these might be used for index to examine treatment effect.

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.
