The purpose of this study was to investigate the effect of short terms weight reduction period on body composition and body fluid. Seven Judo athletes (21±1.21 yrs) were matched and randomly placed. Body weight reduction period consists of 7 day. Each groups reduced body weight by 3%(2th day from pre weight reduction), 5%(4th day from pre weight reduction, 7%(7th day) and investigated the recovery period on 3 hour after breakfast, lunch, and 1day, 2day after 7% body reduction. Weight reduction reduced weight during weight reduction period then returned to baseline during recovery(p<.05) and decreased LBM, electrolyte, and immune function and then increased in recovery period to baseline. In conclusion, weight reduction of Judo athletes caused the change biological variable and performance and STWR may detrimental effects body' homeostasis.

Ovarian pregnancy is an uncommon form of the ectopic pregnancies. The ovarian vascularity results in maternal hemorrhage early in the first trimester, which disrupts the pregnancy and usually ruptures the ovary with sufficient hemoperitoneum to require emergency operation. This report presents 10 cases of ovarian pregnancy by retrospective review between January 1986 and December 1995 at the Department of Obstetrics and Gynecology, Soonchunhyang University Hospital. There was 19,849 deliveries and 637 ectopic pregnancies during same period. It showed that the incidence of ovarian pregnancy was 3.21 % of all ectopic pregnancies. The clinical features of ovarian pregnancy revealed that abdominal pain was the major symptom, and history of amenorrhea was obscure. Because of life-threatening course, the early diagnosis and treatment of ovarian pregnancy is important. The clinical diagnosis of ovarian pregnancy was more difficult than that of tubal pregnancy.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about ‘Table etiquette’, ‘Reasons for eating fruits and vegetables’ (78.7%), ‘Food waste and environment’ (72.3%), ‘Healthy snacks’ (55.7%), ‘Food sanitation’ (52.3%), ‘Food culture of foreign countries’ (48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about ‘basic food preperation’ (p < 0.01). They had learned ‘Nutrients for body’ and ‘Food waste and environment’ in school, ‘Healthy weight loss’, ‘Food culture of foreign countries’, ‘Food circulation’ on television, Most content (‘Table etiquette’, ‘Simple cooking’, ‘Food sanitati n’, ‘Eating behaviors for health’, ‘Reasons for eating fruits and vegetables’, ‘Healthy snacks’) was learned from parents. The practice after nutrition education was higher in ‘Table etiquette’ (2.14), ‘Eating fruits and vegetables’ (2.07) than others compared with education experience. The most reason of non-practice on nutrition information was ‘Troublesome’. In ‘Nutrients for body’, a boy answered ‘Difficult for practice’ 20.0%, a girl answered ‘Difficult to understand’ 32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the ‘Nutrients for body’ (49.6%), ‘Food sanitation’ (44.5%) because of ‘important content’,‘Basic food preparation’ (40.6%), ‘Food culture of foreign countries’ (36.3%) because of ‘interesting content’, ‘Healthy weight loss’ (52.0%), ‘Eating behavior for health’ (44.5%) and ‘Healthy snacks’ (33.7%) because of ‘need for my health’.

This paper presents adaptive equalizer using LMS(least mean squares) algorithms for adaptive nonlinear filters equipped with bilinear system models. Bilinear models are attractive for adaptive filtering applications because they can approximate a large class of nonlinear systems adequately, and usually with considerable parsimony in the number of coefficients required. The severity of the ISI is directly related to the spectral characteristics of the channel and not necessarily to the time span of the ISI. This paper reduces ISI of the nonlinear channel. This paper generated a nember of data from a received signalwaveform with a symbol and proposed a new adaptive equalizer to update adaptive parameter from this data and method to use protocol analyzer.

VoIP 서비스를 위한 SIP 서버의 설계 및 구현

We can foresee the rapidly growing of users by development of VoIP Service what can transmit a voice signal with low cost among a lots application using internet. VoIP need a standardized protocal that is able to do signaling for offering a high quality of service such as mobility, universal number, multiparty conference, voice mail, automatic call distribution. At the present time, A base composition elements of SIP are developing for offering VoIP based SIP(Session Intiation Protocal) in the inside and outside of the country, because SIP of IETF which has a strength from ´fast connection´, ´parsing´& ´easy to compile´ points of view. This paper suggests a ´Type of Hybrid SIP Server´ for providing some services as ´a reducing load of SIP Server that process a request method from users´, ´efficiency of managing networks´, ´offering services to many users´.

ATM 망에서 MARS와 RSVP를 이용한 효율적인 IP 멀티캐스팅

김진수,양혜권 국립7개대학공동논문집간행위원회 2001 공업기술연구 Vol.1 No.-

Various multi-media applications are occured as Internet expanded. Real-time Internet multi-media service, for example audiovisual-conference, Internet-broadcasting and VOD, require fast data transmission, QoS, IP multicast. MARS is porposed to support IP multicast in the ATM Networks based on Internet, and RSVP is proposed to guarantee QoS in the Internet which is originally based on only best-effort service. In this paper, we propose two mechanisms to support IP multicast service involving QoS support over the ATM networks with MARS architecture based on multiple MCSs. In the first mechanism, when an ATM host requests joining into a specific multicast group, the MARS selects a proper MCS among the multiple MCSs to minimize the average time of transfer delay between the sender and the group members. In the second mechanism, when the RSVP reservation message from group member arrive at the MARS, the MARS which can process the RSVP reservation message select again the MCS with using the MCS management table. Fially, we recommend the mechanism to keep the QoS of Internet service and to reduce the the processing-overhead between MARS and MCS.

This paper suggests a contingent perspective for analyzing critical success factors of information systems by organizational characteristics in Korean firms. The contingent perspective includes such corporate characteristics as industry, strategy, value-added application, and corporate culture. The information technology should be introduced for firms to cope with the environment and in the introduction of information technology means that the infrastructure or ability for organizational characteristics is established. But whether the firm is successful to the introduction of information technology or not depends on its specific corporate culture. This research analyzed 25 firms in various industries, and that the domestic small and medium firms consider some issues-support of top management, for malization of standard architecture, user involvement, high quality software, etc.- as the necessary ones. It also found through ANOV A that organizational characteristics highly influences the critical success factors of IS the corporations face.

Authors report a first Korean case of polyneuropathy in an acrylamide producing factory together with an environmental and epidemiologic survey for the ten workers of the same workplace and 46 workers in the production and manufacturing acrylamide in Ulsan, Korea. The case is 30 years old man who worked in the production of the acrylamide for two years. In August, 1997, he had a weakness of the lower extremity with loss of body weight of 15 Kg which progressed to paresthesia of the limbs, the loss of vibration sense, difficulty in walking, speech disturbance, dysuria, constipation, difficulty in erection and swallowing difficulty. Neurologic examination showed a complete loss of vibration and position sense, and loss of deep tendon reflex in all the limbs. There was a contact dermatitis-like skin lesion on the feet. Electrodiagnostic test showed a generalized polyneuropathy of moderate degree involving motor and sensory component of peripheral and cranial nerves. After 8 months' cessation from exposure and supportive care, his symptoms were completely resolved, but abnormality in electrodiagnostic test and vibrotactile perception threshold still persisted, although much improved than before. There were 11 workers in the same workplace of the case, producing acrylamide by microorganism as a catalyst. Environmental monitoring of the workplace revealed air borne concentration of the acrylamide to be from 0.05 to 0.23 mg/m3 by personal sampling and from 7.65 to 11.65 mg/m3 by area sampling during filter exchanging process, which far exceeds TLV-TWA of 0.03 mg/m3. However, acrylamide was not detected from the plasma of the workers. Symptom questionnaire showed a markedly higher complain of neurologic symptoms, compared to the workers of the other acrylamide producing companies. Electrodiagnostic test showed a several workers are in the lower normal range without definite abnormality. Vibrotactile perception threshold by Vibratron Ⅱ showed a significantly increased threshold in the workers of the same workplace compared to the other acrylamide workers and significantly decreased test score of color vision compared to normal controls. After improvement of the production process and strict wearing of the protective device, most workers reported the improvement of clinical symptoms, but vibrotactile perception threshold was not improved. These result suggests the need for the effective environmental monitoring together with a periodic biological monitoring. Development of effective screening test is urgently needed to control and assess the skin absorption of acrylamide.
