국제인쇄산업대전 - "한국 인쇄산업의 동향과 수출전략"

김남수,Kim, Nam-Su 대한인쇄문화협회 2011 프린팅코리아 Vol.10 No.11

한국인쇄산업은 전반적으로 외형의 감소세를 보이고 있다. 이는 수년째 사업체수 및 종사자수가 감소한데 따른 것이다. 이에 비해 인쇄시설의 고급화와 IT시대를 맞아 자연스러운 구조조정이 진행된 결과로 출하액과 부가가치는 지속적인 증가세를 보이고 있다. 국제인쇄포럼에서 김남수 대한인쇄문화협회 회장이 발표한 내용을 요약 정리한다.

The frequeney of fasting hyperlipidemia increases in most hypothyroid patients. However, the cause and mechanism of hyperlipidemia in primary hypothyroidism is not known. In this study, the genetic factor of the hyperlipidemia in primary hypothyroidism patients by the apolipoprotein E(Apo E) gene polymorphism was investigated. Apo E gene polymorphism of the 51 primary hypothyroidism patients and healthy control persons was analysed by modified Amplification Refractory Mutation System(ARMS) technique. Concurrently, total cholesterol, triglyceride, HDL cholesterol and total T₃, free T₄, TSH were measured by standard laboratory methods. The apo E gene allele and phenotype frequency in hypothyroid patients were similiar with those in healthy control person. The ap E3 allele frequency of hypercholesterolemic group was slightly decreased and the apo E4 allele frequency showed the increasing tendency. The apo E3/3 phenotype of hypercholesterolemic group was decreased and apo E2/4 and apo E3/4 phenotype of hypercholesterolemic group was increased. In conclusion, there was no difference in Apo E polymorphism between hypothyroid patiesnts and healthy control. Apo E polymorphism seemed to be associated with hypercholesterolemia in primary hypothyroidism. Further investigation is needed for the another cnadidate genes and apolipoprotein analysis in primary hypothyroidism and environmental factors.

레일레이 페이딩 하에서 CSI 지연이 있는 DOT 협동 릴레이 시스템의 오수신율

김남수 청주대학교 2012 産業科學硏究 Vol.29 No.2

Recently, the cooperative relay system which reduces the power consumption and increases the system performance with simple deployment of the network has been studied widely. Usually, the system selects the maximum signal-to-noise ratio(SNR) relay for simple realization and for performance improvement, however, the effect of the system delay of the channel state information(CSI) has been neglected. The performance degradation caused by the delayed CSI has been researched the other system, but the effect to the double opportunistic transmit (DOT) cooperative diversity system which is more recently proposed has not been studied. In this paper, we derive the closed form expression which includes the effect of the delayed CSI, that causes inevitably for the selection of the maximum SNR relay, to the system performance and reviewed with numerical examples in DOT system. Numerical results show the performance degrades as the number of the relay reduces. Also when the channel gain of the direct path, source-relay path, is greater than that of the indirect path, relay-destination path, it is noticed that the performance degradation caused by the delay of CSI is reduced. As we expected, the less delay of CSI increases the correlation coefficient, consequently improves system performance. It is necessary to minimize the delay of CSI because that affects directly to the system performance.

General mobile environments in urban areas does not exist the direct path between a source and a destination, caused by the interception from the buildings and mobile vehicles. In that case, we introduce a relay to deliver the source information to a destination. There are many relays between a source-destination path, however the introduction of many relays causes the inefficient use of the communication resource. Recently, the best single relay is selected among them for the performance improvement and better utilization of the resource. Unfortunately, there are no studies for the performance comparisons between the relay selection rules. In this paper, we derive the outage performance of Max-max, max-min, and Max relay selection rules analytically. We noticed that the Max-max rule denotes the best performance and the Max rule has worst performance. On the other hand the location of the selected relay affects the system performance; when the relay locates on the middle between the source-destination path, the lowest outage probability is noticed. When the relay approaching to the source or the destination the outage probability is increasing. By applying the Max selection rule to the source-relay path, the performance is decreasing as the relay approaching to the destination.

The aim of this study was to evaluate the effect of swimming exercise during 12 weeks on body fatness and fat distribution. Subjects consisted of a total of 60 adult, women as the control and 30 adult, women as the swimming exercise subjects. The control subjects did not have histories of ongoing or vigorous exercise and they agreed not to participate in any regular exercise while serving as control subjects in this study. Swimming exercise was treated as a single type of exercise .Swimming exercise subjects participated in structured swimming classes at K University swimming pool which offered three days per week for approximately one hour per session for 12 weeks. Subjects were tested before and after 12 weeks of exercise training Anthropometric variables included: body mass, height, chest , upperarm, waist, hip, thigh and calf circumferences, skinfolds at the triceps, subscapular, abdominal, suprailiac, thigh and medital calf sites. The body mass index was calculated as body mass (kg) divided by stature (m) squared . Body composition parameters were assessed by bioelectrical impedance analysis (Model 310, Biodynamics, Seattle, U.S.A.) There body fat distribution indices were calculated by the ratio of waist to hip circumference(WHR) and the ratio of waist to thigh circumference(WTR), and ratio of averaged central to averaged peripheral skinfolds(CPR)=(subscapular+suprailiac )/(triceps +thigh). All these indices are known to have been used in the literature. The results showed that no significant differences were found in anthropometric characteristics for control subjects between pre and posttests. However, there were significant mean differences(p<0.05)for triceps(26.0mm vs 23.9mm). abdominal (41.8mm vs39.3mm). suprailiac (35.0mm vs 31.2mm) and thigh (34.9mm vs 31.8mm) skinfolds between pre and posttests in swimming exercise group. Between the pre and posttests, control subjects increased in body fatness and fat distribution indices as evidenced by an increase in percent fat(+0.8%) and WHR(+0.04) On the contrary, swimming exercise subjects decreased significantly(p<0.01) in sum of skinfolds (-18.6mm) and WTR(-0.04)

The purpose of the study was to estimate body composition, physical fitness on three somatotype groups. Sample consisted of 653 middle school boys in Kyunggi-do. The subjects were divided into three somatotype groups. Anthropometric measurements included Height, Weight, Sitting-height, 6 Circumferences, Humerys & Femur dia-meters, 5 Skinfolds taken at Triceps, Subscapular, Suprailiac, Thigh and medial calf. Percent Body fat, Fat mass, Fat-free mass, Total body water included were computed by bio-electrical impedance analysis. Physical fitness included Flamingo balance, Plate tapping, Sit & reach, Standing broad jump, Grip strength, Bent arm hang, 50m Shuttle run and Endurance run. All data were analysed by SAS personal software program. Mean and standard deviations were calculated for each parameters. ANOVA was applied for the comparison of Body composition & Physical fitness among somatotype groups. Duncan's multiple range were used for the significance of parameters between groups. The result of the study were as follows: 1. In factor of percent fat, fat mass, fat-free mass, basal metabolic rate, total body water, body mass index, waist/hip ratio appeared Endomorphy average the highest in three groups and waist/thigh ratio appeared Ectomorphy average the highest in three groups. 2. In factor of flamingo balance, sit and reach and grip strength appeared Endomorphy average the highest in three groups and standing broad jump, bent arm hang, shuttle run 50m and endurance run appeared Ectomorphy average the highest in three groups. 3. The correlation coefficient between grip strength and fat-free mass, basal metabolic rate, total body water were revealed as the highest correlation in Mesomorphy.
