The human resources of an enterprise is very important to survive in these days of business environment. This study investigates the influence of four behavioral types in MBTI (Myer-Briggs Type Indicator) and working conditions on organizational effectiveness. Job satisfaction and immersion have been regarded as a key conception of organizational effectiveness. The focus of this study is to investigate the effects of R&D employee's four behavioral types in MBTI and working conditions on organizational effectiveness. The results of this study show that organizational effectiveness is influenced by personality types and working conditions. According to the result, First, about the analysis of differences in job satisfaction, EP (Extraversion Perceiving)-type (3.56) and EJ (Extraversion Judging)-type (3.43) are higher than IJ (Introversion Judging)-type (3.07) and IP (Introversion Perceiving)-type (3.03) of four behavioral types in MBTI. So an enterprise makes various efforts to enhance job satisfaction for IJ (Introversion Judging)-type and IP (Introversion Perceiving)-type. Second, For improving the organizational effectiveness that is job satisfaction and immersion, an enterprise must make favorable working conditions to each four behavioral types in MBTI of R&D employees. In order to improve job satisfaction, the enterprise will provide IJ (Introversion Judging)-type with support for collegiality and IP (Introversion Perceiving)-type with good relationships with superiors. and also the enterprise gives autonomic authority to EJ (Extraversion Judging)-type. Finally, in the case of EP (Extraversion Perceiving)-type, the enterprise must admit failure for efforts. In order to improve job immersion, the enterprise will provide IP (Introversion Perceiving)-type with good relationships with superiors, the vision of company and compensation for creative work. and also the enterprise gives autonomic authority to EJ (Extraversion Judging)-type.

Choi et al./sup 1)/ presented the total Lagrangian formulation based upon the degenerated shell element. Geometrically correct formulation is developed by updating the direction of normal vectors and taking into account the second order rotation terms in the incremental displacement field. Assumed strain concept is adopted in order to overcome the shear locking phenomena and to eliminate the spurious zero energy mode. In this paper, for the ultimate strength analysis of stiffened shell structures considering effects of residual stresses, the return mapping algorithm based on the consistent elasto-plastic tangent modulus is applied to anisotropic shell structures. In addition, the load/displacement incremental scheme is adopted for non-linear F.E. analysis. Based on such methodology, the computer program is developed and numerical examples to demonstrate the accuracy and the effectiveness of the proposed shell element are presented and compared with the results in literatures.

This study conducted observations at 72 traffic lights and road signs in Sejong-si, Korea from March to June 2019 in order to analyze nest-site, nest-site characteristics and feeding behavior in Tree sparrow (Passeer montanus) in urban. Feeding behavior during breeding season in 2019 was investigated at 10 Town representing traffic facilities installed on the road located in the center of the city and 10 Riverside Geumgang river's riverside road. We fitted both general linear model and regression model to our field data and estimated the spatial variation of initial date of the first feeding (i.e., being date of breeding) and the total number of caterpillar fed by parents per hour. Our results showed that the frequency of nest building on artificial structures, such as traffic lights, was about 26% higher and about 8 days earlier in the riverside. In particular, the first feeding was significantly faster when the nearest distance between nest to green field as foraging site was shorter whereas there was no significant effect of the number of nest within 50 meters on the first feeding. Number of caterpillars fed by parents was higher in the Riverside than in the Urban, and especially the number in the second brood was sharply decreased in the Urban. As we estimated average amount of caterpillars per hour to 446 traffic safety facilities in Sejong-si, it was estimated that Tree sparrows fed 18,742.8 caterpillars per hour during the breeding season. In this study, we showed that characteristics of nests built in artificial structures and feeding behavior in order to analyze effects of environmental condition in urban on life-history traits during the breeding season. Finally, we discussed the conservation of birds in urban and pest control effects.

Purposes: In this study, we examined the factors which silenced the organizing members and how the factors affects deprivation of employment about the organization culture, the organizational silence, and the turnover intention. Methodology: In order to research, we carry out a survey on 400 employees of small and medium hospitals. Among them, 321 questionnaires were used for actual analysis, excluding insincere respondents, non-responders or duplicate respondents. In order to verify the hypotheses in this study, we conduct the covariance Structural Equation Model(SEM). Finding: We obtained results using following hypotheses. First, ''The organization culture has an effect on the turnover intention.'' Second, ''The organization culture has an effect on the organizational silence'' Third, ''The organizational silence has a influence on the turnover intention.'' Finally, ''When the organization culture mediates the organizational silence, the adaptation relationship of the ornization effectiveness is different.'', as the key hypothesis, showed that the agreement culture, rational culture, and hierarchical culture of the organization culture type were statistically significant. The organizational silence as a parameter has the partial mediating effects(-) because it has direct and indirect effects. Practical Implications: The results of this study showed that the reason for the organizational silence of the organizing members is that the organization culture by a grade of rank is the largest and these the organizational silence affects the turnover intention.

The study analyzed the heat losses and the building energy efficiency grade by the energy simulation using the ENERGY# and ECO2 programs for the three types of Standard design of rural houses. It was calculated the energy efficiency rating by the ECO2 program for the rural housing standard design, and the energy demand and the energy consumption by each factor were compared and analyzed. And it analyzed energy consumption by element of each house by ENERGY # program. As a result, first in the evaluation of the energy efficiency grade of buildings by the ECO2 program, the rating for primary energy requirement for the housing newly built by the standard design of rural house is expected to range from 2 to 4 with 189.3 to $238.7kWh/m^2.a$. Second, the energy loss of each part of standard design of rural housing occurs in the order of ventilation 39%, window 33%, outer wall 14%, roof 9%, bottom 5%, and energy loss through ventilation and window occurs more than 70%. Third, the most beneficial effects on the energy efficiency grade is obtained the lowest grade of all three types by 2 when the lowering of the window and door heat transmission rate and the lowering of the light density, and the heat exchange ventilation device is not installed. Fourth, in the standard design of rural housing, the energy demand is occupied by heating > hot water > lighting order, and the order of the weight is changed in order of heating > lighting > ventilation > hot water. Fifth, building energy efficiency assessment system needs to establish policy for fixing rural housing energy as a practical device to ensure energy performance and quality.

Background: The aim of this study was to investigate the anti-cancer effects and mechanisms of immunochemotherapy of 5-fluorouracil (5-FU) and interleukin-2 (IL-2) on non-small cell lung cancer (NSCLC) A549 cells. Materials and Methods: In order to detect whether 5-FU+IL-2 could effectively inhibit tumor growth in vivo, we established an A549-bearing nude mouse model. The cytotoxicity of natural killer (NK) cells was evaluated using a standard chromium release assay. To evaluate the relevance of NK cells in 5-FU+IL-2-mediated tumor inhibitory effects, we depleted NK cells in A549-bearing mice by injecting anti-asialo-GM-1 antibodies. Effects of 5-FU+IL-2 on the expression and promoter activity of NKG2D ligands (MICA/MICB) in A549 cells in vitro were also assessed. Results: In A549-bearing nude mice, combination therapy significantly inhibited tumor growth in comparison with monotherapy with 5-FU or IL-2 and enhanced the recognition and lysis of tumor cells by NK cells. Further study of mechanisms showed that NK cells played a vital role in the anticancer immune response of 5-FU+IL-2 immunochemotherapy. In addition, the combination therapy synergistically stimulated the expression and promoter activity of MICA/MICB. Conclusions: 5-FU and IL-2 immunochemotherapy significantly inhibited tumor growth and activated NK cytotoxicity in vivo, and these effects were partly impaired after depleting NK cells in tumor-bearing mice. Combination treatment of 5-FU and IL-2 upregulated the expression and the promoter activity of MICA/MICB in A549 cells, which enhanced the recognition of A549 cells by NK cells. All of the data indicated that immunochemotherapy of 5-FU and IL-2 may provide a new treatment option for patients with lung cancer.
