This paper is to aimed to design a model of Korea defense information resource management structure from the viewpoint of system's approach, especially focusing on planning/programming procedures, organizational structure and business process re-engineering. The author analyzed current projects and plans on the field of Korea defense information systems, for finding what kinds of problems and why the problems occurred. The author concluded that many problems came from wrong approach of previous information resource management. Highlights of the proposed model are as follows: 1) Planning and programming structure must be considered as a major information resources and it must be managed as a key role through the whole system life cycle; 2) Organizational structure should be properly set up for managing and implementing information system projects; 3) Business process should also be analyzed thoroughly for re-engineering and innovating current inefficient organizational structure. These three additional viewpoints added to previous model for improving Korea defense information resource management.

Prediction and control of the thermal distortion is particularly important for the design and manufacture of welded thin metal structure. In this study, numerical computations are performed to analyze effect of structure section shape and weld line location on distortion. In addition, this study aims to develop a thermal elasto-plastic simulation using finite element method to predict distortion, with particular emphasis on bending deformation generated in outline welding of a thin box structure. From the numerical analysis, it was revealed that the section shape and weld line location play an important role on the welding distortion. Among 3 types of section shape design proposed in this study, the least deformation remained in the two path welded structure.

Response of harbor structure to environmental loads such as wave load, impact load, ship's contacting load, is a fundamental factor in designing of the structure's optimal configuration. In this paper, typical environmental loads against coastal structures are investigated for designing of the optimal harbor structure. Loads to be considered here are wave load, impact load and contacting load due to ship mooring. Statistical analysis for several harbor structure types under the corresponding loads is carried out, followed by investigation of effect of individual environmental load. Based on these, the optimal configuration for the harbor structure is obtained after considerable engineering process. Estimation of contacting load of the ship is suggested using effective energy concepts for the load, and analysis of structural behavior is done for the optimal designing of the structure in the particular load. A guideline for the design process of the harbor structure is established, and safety of the structure is examined by proposed scheme. For verification of the analytical approach, various steel-piled coastal structures and caissons are chosen and relevant structural analyses are carried out using the Finite Element Methods combined with MIDAS/GTS and ANSYS code. It is found using the Morison equation that impact load cannot be a major load in the typical harbor structure compared with the original wave load, and that configuration shape of the structure may play an important role in consideration of the response criteria.

Purpose - Capital structure adjustment costs influence the test of the standard trade-off theory of capital structure. We investigate whether there exist economically significant capital adjustment costs in the Korean retail industry. Research design, data, and methodology - This paper adopts the model of Leary and Roberts(2005) to obtain the hazard rate of capital structure variations. The retail firms traded in the KOSPI and KOSDAQ markets are analyzed from 2000 to 2016. Results - The empirical analysis shows infrequent capital structure adjustments in the Korean retail firms. The duration analysis emphasizes that the fixed adjustment cost plays an important role in the determination of capital structure adjustments for the Korean retail firms. Yet, even after taking account of infrequent capital structure adjustments, the trade off theory only weakly explains the capital structure variations of the Korean retail firms. Conclusions - This paper confirms the existence of capital structure adjustment costs for the Korean retail firms. Our results argue for the significance of fixed adjustment costs in capital structure adjustments. Such emphasis on the fixed cost is inconsistent with the existing studies. The trade off theory does not successfully explain capital structure policy in the Korean retail firms even after considering adjustment costs.

Active sites and substrate bindings of 1-aminoxyclopropane-1-carboxylate oxidase (MD-ACO1) catalyzing the oxidative conversion of ACC to ethylene have been determined based on site-directed mutagenesis and comparative modeling methods. Molecular modeling based on the crystal structure of Isopenicillin N synthase (IPNS) provided MD-ACO1 structure. MD-ACO1 protein folds into a compact jelly roll shape, consisting of 9 ${\alpha}$-helices, 10 ${\beta}$-strands and several long loops. The MD-ACO1/ACC/Fe(II)/Ascorbate complex conformation was determined from automated docking program, AUTODOCK. The MD-ACO1/Fell complex model was consistent with well known binding motif information (HIS177-ASP179-HIS234). The cosubstrate, ascorbate is placed between iron binding pocket and Arg244 of MD-ACO1 enzyme, supporting the critical role of Arg244 for generating reaction product. These findings are strongly supported by previous biochemical data as well as site-directed mutagenesis data. The structure of enzyme/substrate suggests the structural mechanism for the biochemical role as well as substrate specificity of MD-ACO1 enzyme.

In the ancient Buddhist temple area, various metal artifacts are still excavated. Therefore, the aim of this study is to approach the characteristics of ancient architecture through ancient metal artifacts. First, metal decoration of ancient architecture appears for the purpose of structure, decoration, arson. Then, as the method of wood structure is developed, the application is separated into structural, functional and decorative purposes. In ancient times, metal decoration has reduced the role of structure, but its decorative role has expanded. Second, various metallic ornaments were used on the roof of ancient architecture. As the wooden technology developed, the metal decoration was gradually omitted while applying the curve to the roof. Third, the metal ornaments used on the roof of ancient architectures include the ridge central decoration, roof top decoration, a nine-ring decoration, gable board Ornamental Metal, corner flower decoration, eaves nail, wind bell. And subsequent research requires a terminology that can link the results of archeology and Buddhist art through excavation as a result of architecture.

RalBP1 associated EPS domain containing 1 (REPS1) is conserved from Drosophila to humans and implicated in the endocytic system. However, an exact role of REPS1 remains largely unknown. Here, we demonstrated that mitogen activated protein kinase kinase (MEK)-p90 ribosomal S6 Kinase (RSK) signaling pathway directly phosphorylated REPS1 at Ser709 upon stimulation by epidermal growth factor (EGF) and amino acid. While REPS2 is known to be involved in the endocytosis of EGF receptor (EGFR), REPS1 knockout (KO) cells did not show any defect in the endocytosis of EGFR. However, in the REPS1 KO cells and the KO cells reconstituted with a non-phosphorylatable REPS1 (REPS1 S709A), the recycling of transferrin receptor (TfR) was attenuated compared to the cells reconstituted with wild type REPS1. Collectively, we suggested that the phosphorylation of REPS1 at S709 by RSK may have a role of the trafficking of TfR.

This study was designed to develop and test a model of the theoretical structure of factors influencing womens’ attitudes toward menstruation, specifically, premenstrual discomfort or pain, negative affect, disability and role acceptance. The conceptual framework was built through a review of the literature. For the purpose of testing the model, data were collected from April to June, 1992 with the use of Menstrual Distress Questionnaire, Menstrual Attitude Questionnaire, Sex Role Acceptance Scale. Data analysis was done with the SPSS PC/sup +/ for descriptive statistics and PC-LXSREL 7.13 for covariance structure. The study subjects consisted of 320 women college students in 2 three-year nursing junior colleges and 1 department of nursing of a college of medicine. The mean age of the subjects was 19, the mean age at monarch was 13.7, the mean menstrual cycle was 29.7 days and the mean menstrual duration was 5.3 days. The amount of menstrual discharge was moderate and the menstrual cycle variability was within 3 days. The score for pain, negative affect and disability were higher during the perimenstrual period than intermenstrual period. The fit of the hypothetical model with the six paths and the empirical data was high [X²(df=4)=. 57 (P=.966), GFI =.999, AGFI =.997, RMR=.008]. The hypotheses were supported on acceptable level of significance. 1) The higher the pain and negative affect, the stronger the disability. 2) The higher the pain, negative affect and disability, the more negative the attitudes toward menstruation. 3) The lower the women's role acceptance, the more negative the attitudes toward menstruation. The model was supported by the empirical data, and thus these results may help nurses and nursing scientists to understand and support these phenomena of womens’ health experience.
