The Korean Society of Nephrology (KSN) end-stage renal disease (ESRD) registry was established in 1985 in which all KSN members are participating voluntarily: the 'Insan Prof. Byung-Suk Min Memorial ESRD Patient Registry'. The ESRD registry committee of KSN has collected the data through the internet online program that was opened in 2001 and revised in 2013. The registry internet program has c...

The Korean Society of Nephrology (KSN) launched the official end-stage renal disease (ESRD) patient registry in 1985, and an Internet online registry program was opened in 2001 and revised in 2013. The ESRD Registry Committee of KSN has collected data on dialysis therapy in Korea through the online registry program in the KSN Internet website. The status of renal replacement therapy in Korea at...

For sustained performance in a dynamic market environment, individuals within an organization must operate in a social network (SN) that promotes knowledge exchanges, encourages knowledge acquisition, and facilitates dissemination of domain knowledge pertinent to the execution of job-related tasks. Research on Knowledge Social Networks (KSN) has hitherto focused on interpersonal social network ...

For given graphs G and H, the Ramsey number R(G,H) is the smallest natural number n such that for every graph F of order n: either F contains G or the complement of F contains H. In this paper we investigate the Ramsey number R(∪G,H), where G is a tree and H is a wheel Wm or a complete graph Km. We show that if n ≥ 3, then R(kSn, W4) = (k+1)n for k ≥ 2, even n and R(kSn,W4) = (k+1)n−1 for k ≥ 1...

Nutrition and doping issues are rarely studied in the sport of tennis. The aims of this investigation were to determine knowledge on doping (KD) and knowledge on sport nutrition (KSN), and corresponding socio-demographic-, sport-, and sport-nutrition- and doping-factors among an international sample of high-level tennis players of both sexes (43 females; 22 years old on average). In the first p...

Abstract Tuntang watershed is one of the national priority watersheds in Jratunseluna river basin that has a big potential for water availability. The development strategic area causes changes land cover which can result reduced catchment areas. purpose this study was to simulate effect change on annual discharge trends and analyze balance projection based change. This uses data 2019 Kedungsepu...

If/ is an irreducible character of Sn, these functions are known as immanants; if/ is an irreducible character of some subgroup G of Sn (extended trivially to all of Sn by defining /(vv) = 0 for w$G), these are known as generalized matrix functions. Note that the determinant and permanent are obtained by choosing / to be the sign character and trivial character of Sn, respectively. We should po...

The sport nutrition and doping are known to be important issues in sports, but there is evident lack of studies which investigated those issues in swimming, especially with regard to parallel analysis of coaches and athletes. The first aim of this study was to compare knowledge of swimming coaches and their athletes about nutrition and doping. Also, we have identified interrelationships between...

The number of patients with end-stage renal disease (ESRD) is rising very rapidly as the number of elderly and patients with diabetes increases in Korea. ESRD Registry Committee of the Korean Society of Nephrology (KSN) collected dialysis therapy data in Korea through an online registry program on the KSN website. The status of renal replacement therapy in Korea at the end of 2009 was as follow...
