An automatic transmission of construction equipment is controlled by hydraulic and electronic system for doing in various functions like as shifting and operation. The shifting is operated by the engaged and disengaged clutch motion from hydraulic power. On the shifting process, suitable pressure control to the clutch is required for smooth shifting. Hydraulic control system in the automatic transmission is divided by the pilot control type and the direct control type greatly. The direct control type has an advantage than the pilot control type. Because the structure is simple, the design and the manufacture are having less troubles and the system can be maximized precision pressure control. However, the excellent performance proportional control valve should be used to achieve proper control-ability. In this study, the dynamic analysis model composing the automatic transmission and hydraulic system for forklift truck is presented to simulate the characteristics of hydraulic system about the direct control type. That model is verified the validity compared the results of the testing examination. Parameters of input signal are analyzed to reduce the output torque according to input control signal is affected in shifting characteristic.

This paper presents the ballistic armor performance examination and thickness estimation for the latest naval ship structure materials in the Republic of Korea. Up to date, research regarding methods of ballistic experiments establishing database on the latest hull structure materials as well as a precise method of estimating required thickness of armor against specific projectiles have been rarely researched. In order to build a database and estimate proper thicknesses of structure materials, this study used four structure materials that have been widely applied in naval ships such as AH36 steel, AL5083, AL5086, and Fiber Reinforced Plastics (FRP). A $7.62{\times}39mm$ mild steel core bullet normally fired by AK-47 gun was considered as a threat due to its representativeness. Tate and Alekseevskii's penetration algorithm was also used to calculate a correction factor (${\alpha}$) and then estimate the armor thickness of naval ship hull structure materials with a given impact velocity. Through live fire experiments, the proposed method performance difference was measured to be 0.6% in AH36, 0.4% in AL5083, 0.0% in AL5086, and 8.0% in FRP compared with the experiment results.

Purpose: The purpose of this study is to investigate how much continuous investment in human capital contributes to increasing labor productivity at not only individual companies but also at the national level, and causes fundamental as well as increases for labor-management conflicts. The current research aimed to empirically demonstrate the importance of human capital investment and furthermore, based on the effect of human resource investment on labor productivity, also re-examine the role of the Labor Commission as well. Research design, data, and methodology: This study was conducted by the Korea Information Service-Financial Accounting System (KIS-FAS) using representative panel data operated by countries to measure whether long-term investment in corporate human resources affects labor productivity. Results: Two distinctive summarized results of the analysis in the Korea Credit Ratings data showed that there was a high positive correlation between corporate human resource investment and economic performance for a ten-year period from 2009 to 2018. Conclusions: The present study concluded that the role of the labor committee should be effectively formed by the labor as a mediation agency and that the role of the mediation committee members should focus more on how to strengthen the human resources management of the union.

This paper delves into the crucial realm of support structures in metal additive manufacturing (AM) processes and their direct impact on the stiffness of printed components. With the continuous evolution of AM technologies, optimizing support structures has become imperative to enhance the overall quality and performance of manufactured metal parts. Therefore, in this study, tensile specimens were manufactured using various representative support design variables such as support type, spacing, and penetration depth, and the differences in displacement-load curve were analyzed though tensile test. Using additively manufactured support shaped tensile specimen, the paper presents a comprehensive examination of the effect of support parameters on their stiffness. The findings contribute to advancing the understanding how to design supports to suppress thermal deformation of metal parts during AM process, thereby paving the way for enhanced design freedom and functional performance in the ever-expanding field of AM.

Purpose: The purpose of this study was to develop a maternal nursing competency reinforcement program for nursing students and assess the program's effectiveness in Korea. Methods: The maternal nursing competency reinforcement program was developed following the ADDIE model. This study employed an explanatory sequential mixed methods design that applied a non-blinded, randomized controlled trial with nursing students (28 experimental, 33 control) followed by open-ended interviews with a subset (n=7). Data were analyzed by both qualitative and quantitative analysis methods. Results: Repeated measures analysis of variance showed that significant differences according to group and time in maternal nursing performance; assessment of and intervention in postpartum uterine involution and vaginal discharge (F=24.04, p<.001), assessment of and intervention in amniotic membrane rupture (F=36.39, p<.001), assessment of and intervention in delivery process through vaginal examination (F=32.42, p<.001), and nursing care of patients undergoing induced labor (F=48.03, p<.001). Group and time improvements were also noted for problem-solving ability (F=9.73, p<.001) and emotional intelligence (F=4.32, p=.016). There were significant differences between groups in self-directed learning ability (F=13.09, p=.001), but not over time. The three main categories derived from content analysis include "learning with a colleague by simulation promotes self-reflection and learning," "improvement in maternal nursing knowledge and performance by learning various countermeasures," and "learning of emotionally supportive care, but being insufficient." Conclusion: The maternal nursing competency reinforcement program can be effectively utilized to improve maternal nursing performance, problem-solving ability, and emotional intelligence for nursing students.

In order to prepare future green hospital architecture authentication system, this study is a comparative year report to Korean, the United States, Japanese, British, Canadian and Australian green building authentication systems. Also, the United States and Australian Green hospital authentication systems were examined, and the authentication items of hospitals were compared with those of civil architecture. Though the examination and analysis, the portion of indoor environmental quality section commonly shows the average of 20.7 percent in all 6 countries. Especially, IAQ(Indoor Air Quality) among inside IEQ(Indoor Environment Quality) is overwhelmingly much treated in Korea, the U.S.A, Canada and Australia. In Japan, heat, light and sound are the important factors for authentication evaluation, while in the U.K light are more emphasized for the authentication. 'LEED for Healthcare' as a hospital evaluation authentication system subdivided currently most. The system includes the detailed and extensive evaluation items ranging from hospital management, traffic, emission, water resources utilization to integrated design and furnishing. These overseas systems should be carefully investigated, researched and analyzed for an appropriate improvement of domestic green hospital authentication system. Also the current evaluation method of IEQ section of Korean GBCC needs to be modified. That's why the method puts too much importance on IAQ in IEQ section.

This paper presents the effects of different phone-like-unit (PLU) sets in order to propose an optimal PLU set for the performance improvement of Korean automatic speech recognition (ASR) systems. The examination of 9 currently used PLU sets indicates that most of them include a selection of allophones without any sufficient phonetic base. In this paper, a total of 34 PLU sets are designed based on Korean phonetic characteristics arid the effects of each PLU set are evaluated through experiments. The results show that the accuracy rate of each phone is influenced by different phonetic constraint(s) which determine(s) the PLU sets, and that an optimal PLU set can be anticipated through the phonetic analysis of the given speech data.
