본 연구는 중년 여성의 일상생활스트레스가 건강과 우울에 미치는 영향과 이 관계에서 영적 안녕과 대처기제의 매개효과와 조절효과를 검증하고자 하였다. 이를 위하여 서울 시내와 수도권에 소재하고 있는 10여개 교회에서 40-50대 여성신도들을 대상으로 조사를 실시하였다. 전체 응답자 중 230명의 자료를 최종분석에 활용하였고, 구조방정식 모형으로 분석하였으며, 구체적으로 경로 분석, 조절효과 분석 등을 실시하였다. 연구결과, 일상생활스트레스는 신체적으로나 정신적인 건강을 해치는 원인으로 작용하고 있고, 우울 수준을 높이는 원인으로 작용하고 있는 것으로 나타났다. 일상생활스트레스는 건강과 우울에 직접적인 영향을 미치며, 동시에 일상생활스트레스는 영적 안녕을 매개로 하여 영향을 미치는 부분 매개 효과를 하고 있었다. 즉 일상생활스트레스는 영적 안녕을 저해하고, 저해된 영적 안녕은 신체 건강과는 연관성이 분명하지 않지만 정신건강을 해치고, 우울 수준을 높이는 것으로 나타났다. 일상생활스트레스가 건강과 우울간의 관계에서 대처기제들의 조절효과를 분석한 결과, 12개 대처기제 중에서 자기비판, 긍정적 해석, 자제 등 3개의 대처기제가 유의한 조절효과가 있는 것으로 나타났다. 이러한 연구결과를 바탕으로 중년 여성의 일상생활스트레스 원과 건강특성 간의 관계에의 부적 영향을 최소화하기 위한 실천에의 함의와 정책 방안을 제시하였다.

The purpose of study is to examine the effects of family support on the life satisfaction of elderly with disabilities and provide a ground necessary to improve it. Research was conducted on 167 elderly with hearing, visual and physical disabilities aged over 60 who were living in Seoul and Pusan. Telephone survey, sign language and interview, in accordance with types of disability, were adopted to collect data effectively. That is telephone survey was used for elderly with visual impairment whereas face-to-face interview for physical impairment and sign language for hearing impairment by volunteers. Collected data were analyzed, using hierarchical regression analysis. This study utilized two different models, direct effect model and buffering effect of social support in order to examine the effects of familial support on the life satisfaction of elderly with disabilities. Research findings suggest that the level of life satisfaction appeared to be low in general among elderly with disabilities and emotional family support exerted a positive effect on life satisfaction. In addition, it is empirically supported that emotional family support buffered the negative effect of economic limitations on life satisfaction. In other words, the effects of economic limitations as stress factor decreased with the increase in the frequency of emotional support, however, the level of life satisfaction decreased at a mercy of the stress factor of economic limitations with the decrease in the frequency of emotional support. Finally, this paper attempted to provide some alternatives to effectively improve life satisfaction among elderly with disabilities based on empirical findings.

Purpose - The current paper not only investigates the intermediating process of the association between job insecurity and organizational performance, but also tries to find a factor which mitigates the negative influence of job insecurity. Design/methodology/approach - By conducting structural equation modeling(SEM) analysis with survey data from 351 employees, this study tried to identify the mediating effect of organizational trust, as well as the moderating influence of ethical leadership in the job insecurity-organizational trust link. This paper built hypotheses that job insecurity decreases the level of employee's organizational trust, then the level of the employee's organizational trust would influence organizational performance. In addition, ethical leadership would function as a buffering factor between the association between job insecurity and organizational trust. Findings - This paper found that job insecurity had a negative influence on employee's organizational trust, and the employee's organizational trust had a positive influence on organizational performance. The ethical leadership mitigated the negative impact of job insecurity on organizational trust. Research implications or Originality - By empirically delving into the importance of ethical leadership and organizational trust to increase organizational performance, this paper may provide top management and leaders in an organization with important insights that they should adequately monitor and manage the level of ethical leadership and organizational trust.

We decided Miomotegawa river was the object of our investigation since it is one of the most important salmon rivers in Japan. A great number of salmonshave returned to the river, and it was expected to contain relatively lower cation concentrations since granite is widely distributed in the river catchment area. The concentration of calcium and magnesium were less than a half of that of other major rivers. The concentration of analyzed parameters indicating water quality effect on salmons, $NO_{3},\;SO_{4}\;and\;NH_{4}$, were 1.37, 4.08 and 0.01mg/l, respectively. Most parameters down stream were greater in concentration than in the upper stream.

Calcium is a vital second messenger for signal transduction in neurons. Calcium plays an important role in almost every part of the human body but in neuronal cytosol, it is of utmost importance. In order to understand the calcium signaling mechanism in a better way a finite element model has been developed to study the flow of calcium in two dimensions with time. This model assumes EBA (Excess Buffering Approximation), incorporating all the important parameters like time, association rate, influx, buffer concentration, diffusion constant etc. Finite element method is used to obtain calcium concentration in two dimensions and numerical integration is used to compute effect of time over 2-D Calcium profile. Comparative study of calcium signaling in two dimensions with time is done with other important physiological parameters. A MATLAB program has been developed for the entire problem and simulated on an x64 machine to compute the numerical results.

Effects of various monosodium glutamate(MSG_ concentration (0-400mg%) on the quality of Korean cabbage kimchi during fermentation at 2$0^{\circ}C$ were investigated. The growth of lactic acid bacteria titratable acidity pH content of thiamine ascorbic acid $\beta$-carotene and sensory evaluation were observed in the presencve of MSG. Titratable acidity was increased in the kimchi contained MSG during the fermentation.l Wheeas the changes of pH in the kimchi contained MSG were similar to those in control, Maximum growth of lactic acid bacteria was observed after 49 hour of fermentation in kimchi contained with 200mg MSG. The might be due to the fact that MSG was given optimum pH for acid bacteria growth because of its buffering action. Therefore the periods of kimchi fermentation were reduced by addition of MSG, MSG also affected on the stability of ascorbic acid thiamine and $\beta$-carotene. According of MSG. MSG also affected on the stability of ascorbic acid thiamine and $\beta$-carotene. According to sensory evaluation MSG reduced sour taste in kimchi which increased edible periods.

We discuss simulation results concerning the performance of the TCP protocol when running over high-speed HFC networks. Hybrid Fiber Coaxial are likely to provide fast and cost effective sup-port to a variety of applications including Video on demand, interactive computer games, and internet-type applications such as Webbrowsing, ftp, and telephony. Since most of these applications, use TCP as the transport later protocol, the key to their success largely depends on the effectiveness of the TCP protocol. In all simulation scenarios the TCP traffic is maxed with some background traffic whose level is taken as a variable parameter. Both the background traffic and TCP traffic are either unshaped, or shaped according to the GCRA algorithm. The effect of the background traffic on the TCP protocol performance is discussed varying the buffering capacity with nodes as well as the peak bit rate that each TCP connection is allowed to use.

The pathophysiology of Gastroesophageal reflux disease (GERD) has been known that it is developed when the offense-primarily the gastric acid-pepsin content of the refluxate-overcomes a 3-tiered esophageal protective defense. consisting of antireflux mechanisms, luminal clearance mechanisms, and tissue resistance. Laryngopharyngeal reflux (LPR), which is known as an extraesophageal variant of GERD, has been considered to be developed by transient lower esophageal sphincter relaxation (TLESR), direct mucosal injury by gastric contents, more sensitive mucosa compared to esophagus, and absence of buffering effect and aggravation of the injury due to pepsin. However, hypothesis of the pathophysiology in both entities are numerous and still lack of understanding for being a theory. There is no conflict that understanding the pathophysiology is necessary for resolving the problems of these diseases and numerous studies and results have been releasing. This review could provide clinicians dealing with GERD and LPR with applicable new information and help for overcoming the clinical obstruction.
