This study examines the relationship of the industry-specific factors that effect innovation of manufacturing technology and the market share within the defense industry. Since the establishment of the basic defense industry framework in 1973, there were numerous interactions of the industry-specific factors of the defense industry structure with the technological innovation and market organization of the defense industry. During last three decades, the domestic defense industry has achieved the considerable level but the framework of the basic system has not developed much in areas of the military science and the defense manufacturing technology. Industry-specific factors were formed in the process and appeared in a variety of behavioral characteristics as subsystems. Currently, there IS a growing trend where the management of defense industry is gradually deteriorating due to limitation of the domestic industry-specific factor (e.g. defense technologies, amount of demand, etc.). If there is a prominent imbalance of the industry-specific factors. it can trigger the potential problem of conflict, lack of cooperation and control, slowing the growth of the manufacturing technology thereby diminishing the market and deteriorating the defense supply/demand relationship. In a research conducted by Joe S. Bain, Bain analyzed the relationship of the traditional industrial organization where industry-specific factor(S) not only impacts the conductor(C). And, conductor(C) influences the shaping of the performance(P) of relationship of the traditional industrial organization. Consequently, the researcher has identified the demand monopoly, barriers to entry, and market competition with comparison of defense industry issues. These defense issues were three industry-specific factors identified, which are 1) The demand monopoly and The entry barriers to new market competition, 2) the industrial technical factor to a production technical competitiveness and a market sharing competitiveness, 3) the probability factor to revolution for military affairs(RMA) and a R&D production. According to baseline with these factors, the following research model is established from the special companies group(Group A), the systematization companies group(Group B), and the general companies group(Group 0. The hypothesis is that if there are more industry-specific factors, then there will be more relationships of defense industry relation statutes. This research is an empirical study on the relationship that the industry specific factors effects the innovation of manufacturing technology and the shaping of the market in the defense industry. Moreover, the existing models to evaluate the industry specific factors of the defense industry IS much to be desired with the controlled statistical analysis of the result. It is vital to study on current situation with suggesting alternative strategy to the efficient strategy. The descriptive analysis approach analysis is conducted with SPSSWIN to conduct reliability test, factor analysis, correlation analysis, cross-tabulation analysis, one-way ANOVA, and multiple regression analysis. However, there were some limitations of the survey such as the rigidity of concept about the technical factors and various market management factors. The wishes is that the decision-maker could be utilized these defence industrial factors to formulate efficient defence policy and strategy in the future.

The purpose of this study was to compare communication and mother-child interactions of reactive attachment disordered children with normal children. The subjects were 24 children and their mothers participated in this study'12 reactive attachment disordered children and mothers, 12 normal children and mothers. The mother and her child were brought into a p]lay room and the mother was instructed to play with her child as she normally would at home. The play situations were videotaped. Tapes were transcribed and transcribed data was analyzed with 13 mutually exclusive categories encompassing pragmatic functions represented in communication form the early stage of multiword speech in childhood. The tapes were analyzed with 10 behavioral mother-child interaction patterns. As the statistical method, t-test and correlation was calculated. The results of this study were as follows : 1) Reactive attachment disordered children used significantly fewer 'filler', 'information', 'requests', 'describes' and 'disscus self'. 2) Reactive attachment disordered children's mother used significantly fewer 'filler' and 'names'. 3) Reactive attachment disordered children used significantly more 'independent play', fewer 'intiates interaction', 'responsiveness' and 'answer' Reactive attachment disordered children's mother used more 'control play', 'observe' and fewer 'initiates interaction'. 4) Children's communication patterns were related lo mother·'s communication and mother-child interaction types. Children's 'filler', 'information requests', 'describes' and 'disscus self' were consistantly related to mother's 'filler' and 'names', (Children's 'filler', 'information requests', 'describes'. 'disscus self' and mother-child's intiates interaction 'responsivness' were significantly positively correlationed and 'independant play', 'control play', 'observation' were significantly negatively correlationed. The results of reveal that communication and mother-child interaction pattern of reactive attachment disordered group was different from normal group and children's communication pattern were influenced by mother's communication and interaction patterns.

Objective: The purpose of this study was to investigate the clinical utility of the Korean Wechsler Intelligence Scale for Children-Fourth Edition (K-WISC-IV) and General Ability Index (GAI) in children with attention-deficit hyperactivity disorder (ADHD). Methods: The GAI and Full Scale IQ (FSIQ) in K-WISC-IV were compared for a group of 79 children with ADHD and 234 normal children. The mean differences within each group were testified by the t-test and Cohen's d. The Wechsler's descriptive classifications for each GAI and FSIQ score were analyzed in the children with ADHD. Additionally, the critical value for the difference between the means of the FSIQ and GAI was calculated in the normal children. Results: The score on the GAI was higher than that on the FSIQ in the children with ADHD, with a mean difference of 2.19 points. The implications of these findings are discussed regarding the cognitive characteristics of the children with ADHD. According to Wechsler's descriptive classification, the application of the GAI showed a lower (7.59%), equal (61.65%) or higher (60.76%) prevalence of ADHD compared to the application of FSIQ. Conclusion: The implications of these findings are discussed regarding the cognitive characteristics of the children with ADHD. The GAI reflecting the attention and behavioral problems in children with ADHD could be utilized as an alternative global intelligence estimate that considers their potential for development.

Objectives : The present study was conducted to evaluate the effects of automatically controlled rotating acupuncture (ACRA) on thermal allodynia in neuropathic pain rats, and to examine whether the endogenous opioid system mediates the effects of ACRA. Methods : For the neuropathic surgery, the right superior caudal trunk was resected at the level between S1 and S2 spinal nerves innervating the tail. Two weeks after the nerve injury, ACRA stimulation with 4 different stimulation conditions (i.e., angle and frequency of rotation: 90o+1Hz, 90o+1/4Hz, 360o+/1Hz, and 360o+1/4Hz) was delivered to the Zusanli (ST36) acupoint for 15 min. The behavioral signs of thermal allodynia were evaluated by the tail immersion test (i.e., immersing the tail in cold $(4^{\circ}C)$ or warm $(4^{\circ}C)$ water and measuring the latency to an abrupt tail movement) before and after the stimulation. In an additional set of experiments, we examined the effects of naloxone (opioid Results : ACRA stimulations under all of the conditions above significantly relieved thermal antagonist, 2mg/kg, i.p.) on the action of ACRA stimulation. allodynia. There is no difference in the anti-allodynic effects among the 4 stimulation conditions. In addition, the effect of ACRA on thermal allodynia was reversed by naloxone pretreatment. Conclusion : These results indicate that ACRA stimulations have relieving effects on thermal allodynia in neuropathic pain rats, irrespective of stimulation parameters, and that this is mediated by the endogenous opioid system.

In this study, we intend to test whether experience variables such as sense, feel, think, relate, and action experiential activities of farming village can be usefully applied to revisit intention. As a result, we found that the sense, relate, and action experiences were adopted, while the feel and think variables were rejected, leading to the conclusion that Schmitt's (1999) experiential marketing theory was also applied to 6th industry experience marketing activities in rural areas. Therefore, the significant effect of rural experience activities on revisiting intention is thought to be related to the fact that they stimulated sensitivities by drawing attention and interest of consumers during the 6th industrial experience configuration, and to the environmental facilities connected to the experience site. The Feel experience has been rejected due to limitation of development of emotional element from the 6th industry certification business experience program, leading to the necessicity for development of a program that can stimulate the consumer's emotions. The reason why the Think experience was rejected is that the experience of the rural area 6th industry did not create surprises or curiosity, and thus does not meet the expectations of consumers. In case of relational experience, experiential marketing through social organizational relationship formation is expanding, and in case of behavioral experience, experience of 6th industry constitutes experience related to interaction with others and lifestyle.

The time for evacuation of residents in emergency planning zone(EPZ) of Uljin nuclear site in case of a radiological emergency was estimated with traffic analysis. Evacuees were classified into 4 groups by considering population density, local jurisdictions, and whether they ate residents or transients. The survey to investigate the behavioral characteristics of the residents was made for 200 households and included a hypothetical scenario explaining the accident situation and questions such as dwelling place, time demand for evacuation preparation transportation means for evacuation, sheltering place, and evacuation direction. The microscopic traffic simulation model, CORSIM, was used to simulate the behavior of evacuating vehicles on networks. The results showed that the evacuation time required for total vehicles to move out from EPZ took longer in the daytime than at night in spite that the delay times at intersections were longer at night than in the daytime. This was analyzed due to the differences of the trip generation time distribution. To validate whether the CORSIM model fan appropriately simulate the congested traffic phenomena assumable in case of emergency, a benchmark study was conducted at an intersection without an actuated traffic signal near Uljin site during the traffic peak-time in the morning. This study indicated that the predicted output by the CORSIM model was in good agreement with the observed data. satisfying the purpose of this study.

Recently, there are an increasing number of studies on the method of wrapping the outer wall of granular piles with geosynthetic fibers such as geotextile or geogrid that has a certain level of tensile strength as an alternative method for the ground improvement techniques. In this study, triaxial compression tests are performed on the sand and clay specimen encased with various textiles to evaluate the reinforcing effect with regard to the tensile strength of the textile. Furthermore, triaxial compression tests are performed on the clay specimen inserted by sand only and sand encased with geosynthetics to compare behavioral differences between the conventional sand compaction pile and geosynthetic encased sand pile with regard to the replacement ratio, ${\alpha}_s$ and the tensile strength of the geosynthetics. Based on the experimental results, the strength enhancement due to the textile is affected by the longitudinal tensile strength rather than the transverse one of the applied textile. The effect of the confinement by the textile encasement results in the large increase of the cohesions. The overall behaviors, such as shear strength, pore pressure parameter at failure and stress ratio, of the geosynthetic encased sand pile is quite different from those of the conventional sand compaction pile.

This study is to investigate the effect of music therapy Program on Problem Behaviors and Social Skills Children with ADHD. The participants of the study were first and second graders in B elementary school in J city. They were observed in unsuitable behavioral patterns in school life by their homeroom teachers. Fifteen participants were divided into control and experimental group: The control group was eight and the experimental group was seven. Group music therapy was conducted two times a week for seven-week period. It took 35-40 minutes per therapy after school. Child Behavior Checklist-Korean, Social Skills Rating System, Social Acceptance were administered in pre- and post-stages. For the analysis of the data, Mann-Whitney U test was used. The findings from the research are summarized as follows: 1) The experimental group who was treated in music therapy showed a positive effect on problem behaviors. That is to say, the participants in the experimental group improved in emotional and cognitive stability while they significantly decreased attack behaviors; 2) The experimental group statistically showed significant improvement in their social behaviors compared to the control group. The music therapy group significantly increased social skills such as cooperation, self-assertion, and self-control. However, they did not improve responsibility as social skills in a significant manner; and 3) The experimental group showed higher degree of social acceptance than the control group. However, the result did not show a significant difference between the groups. In conclusion, the study proved positive effects of music therapy on ADHD children's uncarefulness, attack behaviors, and social skills for seven-week experimental period.

Experimental and analytical studies on the behavioral characteristics of a pre-stressed (PS) steel girder are conducted to investigate the effects of deviators on the non-linear inelastic properties of the PS system. In this regard, 4 test specimens consisting of a steel H-beam, a straight cable with eccentricity, anchorages, and deviators are built and failure tests are performed under two-point loading. In addition, in-plane elastic deformation theories for the PS system without a deviator, and with three deviators at regular intervals are analytically formulated and solved using a symbolic calculation technique. To verify the validity of the experimental and the proposed analytical theories, the results obtained using FEM models composed of beam elements, rigid beam elements, and truss cable elements, are compared to the experimental results and the analytical solutions. As a result, it is determined that externally installed un-bonded deviators inhibit flexural deformation of the deformed beam to such an extent that their elastic stiffness, and failure strength are significantly improved compared to those of the PS system without deviators.

The cyclic behavior and energy dissipation mechanism of short coupling beams with various reinforcement layouts were studied. For numerical analysis of coupling beams, nonlinear truss model was used. The results of numerical analysis showed that the coupling beams with conventional reinforcement layout showed pinched cyclic behavior without significant energy dissipation, whereas the coupling beams with diagonal reinforcement exhibited stable cyclic behavior without pinching. The energy dissipation of the coupling beams was developed mainly by diagonal reinforcing bars developing large plastic strains rather than concrete which is a brittle material Based on this result, simplified equations for evaluating the energy dissipation of coupling beams were developed. For verification, the predicted energy dissipation was compared with the test results. The results showed that the simplified equations can predict the energy dissipation of short coupling beams with shear span-to-depth ratio less than 1.25 with reasonable precision, addressing various design parameters such as reinforcement layout, shear span-to-depth ratio, and the magnitude of inelastic displacement. The proposed energy equations can be easily applied to performance-based seismic evaluation and design of reinforced concrete structures and members.
