The purpose of this study is to investigate the relationship between post - employment job satisfaction and both short-term (4-12 weeks) and long-term (12+weeks) on-site training. For this purpose, 405 graduates who had completed on-site training (205 short-term, 200 long term) during the school year were surveyed. The results of the comparative analysis of both short-term and long-term on-site training participants are as follows: In both short-term and long-term on-site training, it was found that on-site performance during the school year did not directly affect post-employment job satisfaction. In the case of short-term on-site training participants, job match and organizational commitment were found to have no mediating effect on the correlation between on-site training performance and job satisfaction. On the other hand, in the case of long-term on-site training participants, the analysis showed that job match and organizational commitment had mediating effects on the correlation between on-site training performance and job satisfaction. These effects are not solely attributable to differences in duration of training; the differences in operating systems and the degree of preparation derived from these systems also affect the level of on-site training for students, businesses, and schools. This paper summarizes these findings and suggests the following improvement plans for on-site training in the future: First, short-term on-site training is required to establish a systematic basis in order to enhance students' preparedness level. Second, both short-term and long-term on-site training should improve the skills and field understanding for students' majors through systematic quality management during the training period. Third, it is necessary for universities to increase expectations and quality of short-term on-site training for all involved while simultaneously reducing the gap between educational goals and practice in this field.

본 연구의 목적은 생태체계이론을 적용하여 노인장기요양보험제도라는 거시체계가 가족관계라는 미시체계에 미치는 영향을 살펴보는 것이다. 이를 위해 『한국복지패널(KWPS: Korean Welfare Panel Study)』 2차년도(2007년)와 4차년도(2009년) 데이터를 활용하여 노인장기요양보험제도의 이용자 및 그 가구원(실험집단)과 비이용자 및 그 가구원(통제집단)으로 구분한 후, 노인장기요양보험제도 이용 전후의 가족관계의 변화를 살펴보았다. 이중차이모델(difference-in-difference model) 분석결과, 생태체계이론은 노인장기요양보험제도와 가족관계를 설명하는 이론이라고 할 수 있다. 주목할만하며 새로운 발견은 우리나라의 노인장기요양보험제도가 소득 효과(income effect)가 아닌 독립효과(independent effect)를 갖는다는 것이다. 이러한 결과는 무엇보다도 점점 더 가족의 의미가 퇴색되어 가족관계가 약화되고 있기 때문이다. 또한 한국의 노인장기요양보험제도가 사회보험으로서의 특징을 온전히 갖추지 못하였기 때문으로 추정된다. 노인장기요양보험은 제도의 포괄성, 급여대상의 보편성, 급여의 적절성, 서비스 접근성 측면에서의 제도개선이 필요하며, 가족친화적 사회복지제도로의 변모가 절실히 요청된다.

Purpose - The purpose of this study was to examine the effects of privatization of Chinese state-owned enterprises (SOEs) on their initial returns and long-term performance after initial public offering(IPO). Design/methodology/approach - This study used 1,599 Chinese IPO firms, some of which were SOEs. The multivariate regression analyses were implemented to analyze their effects. Findings - First, the privatization of SOEs does not have any statistically significant effect on the initial return of IPO firms. Second, the shareholdings of government prior to IPOs for both privatizing of SOEs and non-privatizing firms and for both exchanges of Shanghai and Shenzhen have a statistically significant positive effect on the initial return of IPO firms. Third, the privatization of SOEs has statistically significant negative effect on the long-term returns of IPO firms. Fourth, the state-shareholdings prior to IPOs have statistically significant negative effects on the long-term return of IPO firms. Fifth, the state-shareholdings of the privatizing SOEs prior to IPOs have statistically significant positive effects on the long-term return of IPO firms. Research implications or Originality - The results imply that the higher shareholdings and ownership of the Chinese government on SOEs reduce the information asymmetry for the investors of IPO shares or maybe due to inefficiency of SOEs prior to IPOs lead to lower offer prices or higher opening prices leading to severe underpricing and relatively lower stock market returns in the long-run both for the privatizing firms and for the higher state-shareholding firms, while both factors interactively improve their long-term stock market returns.

Long-term deformation of a steel-reinforced concrete (SRC) column is different from that of a reinforced concrete (RC) column due to the different moisture distribution. Wide-flange steel in an SRC column obstructs diffusion and makes long-term deformation slower. Previous studies analyzed the characteristics of long-term deformation of SRC columns. In this study, an additional experiment is conducted to more precisely investigate the effect of wide-flange steel on the long-term deformation of SRC columns. Long-term deformation, especially creep of SRC columns with various types of wide-flange steel, is tested. Wide-flange steel for the experiment is made of thin acrylic panels that can block diffusion but does not have strength, because the main purpose of this study is to exclusively demonstrate the long-term deformation of concrete caused by moisture diffusion, not by the reinforcement ratio. Experimental results show that the long-term deformation of a SRC column develops slower than that in a RC column, and it is slower as the wide-flange steel hinders diffusion more. These experimental results can be used for analytical prediction of long-term deformation of various SRC columns. An example of the analytical prediction is provided. According to the experimental and analytical results, it is clear that a new prediction model for long-term deformation of SRC columns should be developed in further studies.

The paper presents a finite element model for studying timber-concrete composite beams under long-term loading. Both deformability of connection system and rheological behaviour of concrete, timber and connection are fully considered. The creep of component materials and the influence of moisture content on the creep of timber and connection, the so-called "mechano-sorptive" effect, are evaluated by means of accurate linear models. The solution is obtained by applying an effective step-by-step procedure in time, which does not require storing the whole stress history in some points in order to account for the creep behaviour. Hence the proposed method is suitable for analyses of composite beams subjected to complex loading and thermo-hygrometric histories. The possibility to accurately predict the long-term response is then shown by comparing numerical and experimental results for different tests.

The IPC(Incremental Prestressed Concrete) which is gradually introducing the tensile force by tendons has been recently developed for reducing the effective depth of PSC bridges. As well known, concrete experiences long-term deformation such as creep and drying shrinkage, and the prediction of the long-term behavior of concrete bridges is essential for both safety and serviceability aspects. This paper was analysed the long-term behavior of a continuous 2-span IPC girder bridge taking into consideration of creep, drying shrinkage and the time of tensile force introduction. As results, the shrinkage of slab concrete increases the negative moment at interior support, and the The difference of concrete ages between slab and girder increases the camber. The effect of initial tensile force is larger than the effect of secondary tensile force in the tendons.

It is necessary to Investigate long-term behavior of vertical members such as column and shear wall because the long-term behavior induces the serviceability problem of reinforce-concrete structures. However, the long-term behavior on shear wall has not been fully studied. Experimental works are performed to understand the time dependent behavior of shear wall, especially the effect of loading area in this research. Three different types of cross sections are adopted, i.e., 10$\times$10 cm, 10$\times$30 cm, and 10$\times$50 cm with the same loading area of 10$\times$10 cm. The creep strains were different from point to point in the section of the shear wall specimen because of the nonlinear stress distribution. The effect of the nonlinear stress distribution was larger in the specimen with the larger width.

The reduction behavior of silver ions to silver nanoparticles is an important research topic in polymer/silver salt complex membranes for facilitated olefin transport, because it has a significant effect on the long-term stability of membrane performance. In this study, the effects of solvent on the formation of silver nanoparticles and long-term membrane performance in polymer/silver salt complex membrane were investigated. This effect was assessed for the complexes of poly(N-vinyl pyrrolidone) $(PVP)/AgBF_{4}$ with the use of ionic liquid (IL), acetonitrile (ACN) and water as a solvent. Membrane performance test shows that long-term stability is strongly dependent on the kind of solvent and arranged: IL > ACN >> water.
