  • The rising value of software developers has made corporations, including IT companies, to focus on recruitment of software developers. However, the domestic software industry, where SMEs represents quite a large proportion of the industry, is facing problems of low rate of human resources and high rate of job turnover. These problems have not been solved until today. This study hypothesizes that software developer's job satisfaction has an effect on organizational engagement and intention to job transfer. The purpose of this study is to provide implications on desirable human resources management and work environment, that lowers intentions to job transfer by elevating job satisfaction of the software developers. The results of the study reveal that among job satisfaction factors, recognition, autonomy, work-life balance, work environment have significant effects on fob satisfaction. Also, the software developer's job satisfaction elevates organizational engagement and lowers intention to job transfer. In addition, job satisfaction is has partly has mediating effect between job satisfaction and intention to job transfer. Several practical implications are discussed.

  • The development of histomorphometric and histodynamic investigations has permitted the description of a specific and complex osteopathy in hyperthyroidism. The increased bone turnover rate in hyperthyroid patients may be accompanied by a considerable bone loss. These features are associated with both inclosed osteoclastic bone resorption and increased osteoblastric bone formation, with an accelerated calcification rate. Conventional biochemical markers of bone metabolism, i.e. serum calcium and alkaline phosphatase and urinary hydroxyproline and calcium are normal in most patients with hyperthyroidism. However, the correlation between serum BGP and serum concentration of thyroid hormon suggests that serum BGP may be a sensitive marker of increased bone formation due to the hypersecretion of thyroid hormones. Any increase in bone turnover, whether focal or diffuse, will result in an increase in $^{99m}Tc-methylenediphosphonate$ uptake (MDP). The measurement of this uptake in hyperthyroid patients by bone provides a sensitive and objective means of quantifying skeletal metabolism. Using a standard shadow-shield whole-body monitor and radioimmunoassay kit, we have measured whole-body retention of $^{99m}Tc-MDP$ up to 24hr and concentration of serum Osteocalcin in 20 patients with hyperthyroidism and in 42 normals. The results were as follows; 1) The average of serum Osteocalcin level in 42 patients with normals was $9.90{\pm}4.87(ng/ml)$ and in 20 patients with hyperthyroidism was $19.54{\pm}5.7(ng/ml)$. Both the averages of serum Osteocalcin and 24hr $^{99m}Tc-MDP$ uptakes in hyperthyroid patients were higher than those in normals. 2) $^{99m}Tc-MDP$ uptakes in skeletal system increased in proportion to normal ageing after 40 yrs old in 42 patients with normals. The average of $^{99m}Tc-MDP$ uptakes in hyperthyroid patients were higher than those in normals without related ageing. 3) A significant relationships between the $^{99m}Tc-MDP$ uptakes and serum Osteocalcin level were peformed (r=0.55, $y=17.58+6.7\times$). From the above results we concluded that the measurement of serum Osteocalcin and 24hr $^{99m}Tc-MDP$ uptakes can be used for evaluation of bone turnover as a specific marker in hyperthyroid patients.

  • The purpose of this study is to seek out effective policy measures for improving the working environment and improving the supply and demand of nursing manpower in Korea, thereby improving the quality of nursing and creating a high-quality work environment to present a plan to secure adequate supply and demand for nursing manpower. To this end, we have looked at ways to secure effective nursing manpower through literature related to Japanese nursing manpower policy, which has similar health systems to Korea. Japan has established a nursing manpower supply policy since 1974, and is making efforts to improve the working environment and re-employment of idle nursing personnel due to frequent turnover and retirement. As a result of these efforts, the turnover rate of new nurses less than one year in Japan decreased to 7.5%, while the rate of new nurses in Korea was 33.9%. In addition, it is possible to consider ways to encourage medical institutions that have actively promoted and hired idle personnel through various incentives and financial support at the central and local levels.

  • Optimal conditions of electroless nickel plating in acid baths has been studied for industrial applications of a developed EN solution. The phosphorus content in the deposition ranges from 8 to $12\;wt.\%$. The investigated EN plating parameters are ion concentrations of nickel and hypophosphite, concentration of reducing and complexing agent, temperature, and pH. The average plating rate of Ni-P deposition was ca. $14{\mu}m/h$. The EN solution used shows a deposition rate of $10{\mu}m/h$ up to seven metal turnovers.

  • Ageing induces huge dramatic change of society and economy rather than simple change of population structure. Ageing causes the decrease of working age population and production capable population, thus this brings growth slowness and long-term stagnation. In addition, progress in ageing decreases saving rate, consequently low saving rate brings about the decrease of country-wide investment resources. This ageing problem which is progressive rapidly needs core competence and implementation of human resource professionals to overcome this kind of environment change. First of all, it needs turnover in thinking way toward talents. Secondly, we need innovation one team to pursue innovation and creativity. Thirdly, it should be considered in a new way with the number of workers and efficiency of personnel expenses. Fourthly, employees should make effort for self-advancement. Under the environment with newly change human resource personnels' function and role should be emphasized to maintain sustainable growth and overcome the change of management environment. Therefore, human resources should be emphasized to become competitive personnel and organization with leading the change master and creating the value of the organization.

  • The breakdown rate of NAD in Salmonella typhimurium was investigated both in aerobic and anaerobic conditions. After NAD is broken down to nicotinamide ring containing moiety, almost all the nicotinamide ring containing moiety recycles back to NAD pool. However almost none of the adenine containing moiety recycles back. We pulse-label the endogeneous NAD with [$\^$14/C]-adenine and [$\^$3/H]- niacin. The remaining [$\^$14/C]-radioactivity in NAD pool at each time was regarded as unbroken portion of NAD, WHERE AS THE OF [$\^$3/H] was served as a total amount of NAD to start with. Under aerobic condition, the half-life of NAD was around 2 hours. However, the breakdown rate was significantly reduced (around 3-5 fold) under anaerobic condition. The observation that under aerobic conditions, NAD turnover is considerably faster than under anaerobic conditions suggests that oxygen has important effect in NAD breakdown.

  • Phosphorus dynamics in terms of specific absorption rate, inflow and outflow rates. turnover rate, demand and supply, and utility index of a high yield Zea mays L. cv. Bokgyo field were evaluated using an analysis of successive production structures. The analysis was adopted for measuring quantitative changes in the population by stratified clip technique on every two weeks during the growing season. The seasonal trends of specific absorption rate (2. 4 mg P/g/day in maximum) and specific absorption efficiency (0. 03) closely correlated with that of relative growth rate of the population. The overall inflow and outflow of phosphorus was 3.41 g P/$m^2$/yr showing the maximum inflow of 2.99 g P/$m^2$/month in July. While the maximum phosphorus standing crop was 1.4 g P/$m^2$ showing the maximum turnover rate of 178% in late June. The accumulation of phosphorus along plant height declined monotonically in stems and roots but increased in foliage after heading. The proportions of the total annual demand of phosphorus were 24.4% for leaves, 22.5% for stems, 49.6% for fruits and 3.5% for roots. These demands were met with internal (18.2 %) and external (81.8 %) supplies. The seasonal highest phosphorus utility index was 1,091 in early June, while the average value was 655.
