낮은 상관 특성과 큰 선형 복잡도를 갖는 새로운 p-진 수열군
김영식(Young-Sik Kim),정정수(Jung-Soo Chung),노종선(Jong-Seon No),신동준(Dong-Joon Shin) 한국통신학회 2008 韓國通信學會論文誌 Vol.33 No.7C
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.

From the Chinese crude drug shin-i, the flower buds of Magnolia fargesii, four sesquiterpene, oplopanoe (1), oplodiol (2), homalomenol A (3) and $1{\beta},4{\beta},7{\alpha}$-trihydroxyeudesmane (4) were isolated. These structures were elucidated and the ${13}^C-NMR$ chemical shifts of these compounds were revised by means of various 2D-NMR techniques.

GIS-based management information system including graphic and attribute data was studied on selected 4 tree and 8 herbs in Mt. Sobaek. G.I.S. with IDRISI software was applicated. The results were as followed ; 1.The use of G.I.S. system made easy to store, manage and update data. It would save time and effort as well as prevent the data lost. Therefore it would make easy to hand over the duty between natural park manager. 2.Overlay method and three- dimensional spatial analysis by DTM would give the better chance to grasp the location of natural resources and to understand environmental information in Mt. So-baek. 3.This method would give necessary information for establishment of management plan. The user would easily understand spatial details by output of overall analysis. 4.Overlay and DTM's analysis could be utilized for management of natural resources and establi-shment of developmental plan in the Mt. Sobaek National Park.

Acute intermittent porphyria is a disorder that results from partial porphobilinogen deaminase deficiency and accumulation of overproducted porphyrin and its precusors. This makes variable manifestations such as abdominal pain, nausea, vomiting, contipation, peripheral neuropathy, seizure, psychotic symtoms, respiratory failure, tachycardia, and hypertension. When acute paroxysmal hypertension presents, it is difficult to differentiate from pheochromocytoma. We experienced a case of young female with acute intermittent porphyria presenting paroxysmal recurrent headache, palpitation, chest discomfort and paroxysmal hypertension. Initially blood pressure was 160/100 mmHg and checked high paroxysmally on follow up. Rhythm was sinus tachycardia. She did not complain any other specific symptoms. Although her clinical manifestations were suspicious for pheochromocytoma, laboratory findings were not compatible to it. In searching other causes of secondary hypertension mimickng ph대chromocytoma, elevated urine porphobilinogen level was detected and we could make diagnosis of acute intermittent porphyria. If AIP was not beared in mind as a cause of secondary hypertension, diagnosis would be delayed more.

Objectives : This study aimed to investigate the prospective associations of premenstrual dysphoric disorder (PMDD) with quality of life, socio-occupational function and disability. Methods : 170 nurses were recruited 6om two general hospitals. Interviews were made at baseline and at four follow-up points (two mid follicular phases and two late luteal phases ofthe two consecutive menstrual cycles). The baseline evaluation Consis-ted of sociodemographic characteristics and menstmal history. PMDD was diagnosed by DSM-IV criteria after observation of the two menstrual cycles. The follow-up evaluations were consisted ofthe World Health Organization Quality of Life-Brief form, the Social and Occupational Functioning Assessment Scale, and the World Health Organization Disability Assessment Scale-II. Results : PMDD was detected 15 (8.8%) of 170 participants. The PMDD group showed significantly worse quality of life and socio-occupational functioning than the none-PMDD group particularly at the late luteal phases. No significant differences were found in sociodemographic characteristics and menstrual history between those with and without PMDD. Conclusion : PMDD was prospectively associated with worse quality of life and socio-occupational functioning in this study group.

Background : Nowadays, it is possible to prolong the life. And to improve the quality of life of the dying patients, they need to receive not only the physical, pscychological, social and spiritual care but also comprehensive and continuous care. Also, doctors have to consider many ethical issues especially in the dying patients. The purpose of this study is to analyze the doctors' attitude of those ethical issues and emphasize the importance of hospice. Methods : During September 1996, doctors who worked for a university hospital participated in this study by responding to the pre-made questionnaire. It dealt with the most suffering pain, the preferred death place, the use of life maintaining equipments, the application of cardiopulmonary resuscitation(CPR) to terminal patients and the doctors' experience and attitude euthanasia. Results : ① The most suffering symptom in dying patients was pain(60.0%). ② The death place was recommended by doctors was home(58.8%) and hospital (15.4%) in order. ③ 56.9% of doctors answered 'the life maintaining equipments isn't needed', 29.2% of doctors answered' according to the case', and 'needed' was 12.3%. ④ The application of CPR to the terminal patients, without the DNR chart, the only 15.4% of doctors answered "Do not CPR." But with the DNR chart, the percents of 'Do not CPR' was increased to 69.2%. The resident group did more CPR than specialist group(p<0.01). ⑤ The 50.8% of doctors agreed with the passive euthanasia. Conclusions : Many doctors follow the family member's opinion in the ethical issues of the dying patients. Euthanasia is forbidden by the law in Korea, but many doctors agree with the passive euthanasia. Hospice can solve the debating ethical issues including the euthanasia.

The purpose of this study is to analyze the visual variation of skilled and unskilled people, and to obtain data necessary for skill improvement of effective handball penalty throw. An eye tracker was used to collect eye movements, concentration points, directions, and paths during penalty throws. The results are as follows: 1) For skilled players, the place where they threw and the place where their eyes were focused matched. 2) There is no difference in the presence or absence of eye contact with the goalkeeper.
