In this paper we proposed the alternative analysis of reliability design using redundancy technique. First, we presented the process for establishing the reliability design alternative analysis process considering the active redundancy and the standby redundancy. and then, the case analysis of A driving equipment was performed in accordance with the reliability design alternative analysis process presented. In case the series reliability design result is not met with the reliability target value. so, the target item for redundancy design of A driving equipment were selected as items with a severity of two or higher. The redundancy design applied with active and standby redundancy techniques were analyzed using BlockSim software. As a result, it was analyzed that reliability design to active redundancy with one of two elements required for A driving equipment is the most efficient compared to the target value of reliability. The results of this study can be usefully used before the reliability design is performed.

The ROK Army must detect the enemy's location and the type of artillery weapon to respond effectively at wartime. This paper proposes a radar positioning model by applying a scenario-based robust optimization method i.e., binary integer programming. The model consists of the different types of radar, its available quantity and specification. Input data is a combination of target, weapon types and enemy position in enemy's attack scenarios. In this scenario, as the components increase by one unit, the total number increases exponentially, making it difficult to use all scenarios. Therefore, we use partial scenarios to see if they produce results similar to those of the total scenario, and then apply them to case studies. The goal of this model is to deploy an artillery locating radar that maximizes the detection probability at a given candidate site, based on the probability of all possible attack scenarios at an expected enemy artillery position. The results of various experiments including real case study show the appropriateness and practicality of our proposed model. In addition, the validity of the model is reviewed by comparing the case study results with the detection rate of the currently available radar deployment positions of Corps. We are looking forward to enhance Korea Artillery force combat capability through our research.

This paper recognized a need in the architecture, engineering, and construction industry for new programs and methods of producing reliable energy simulations using BIM (Building Information Modeling) technology. Current methods and programs for running energy simulations are not very timely, difficult to understand, and lack high interoperability between the BIM software and energy simulation software. It is necessary to improve on these drawbacks as design decision are often made without the aid of energy modeling leading to the design and construction of non-optimized buildings with respect to energy efficiency. The goal of this research project is to develop a new methodology to produce energy estimates from a BIM model in a more timely fashion and to improve interoperability between the simulation engine and BIM software. In the proposed methodology, the extracted information from a BIM model is compiled into an INP file and run in a popular energy simulation program, DOE-2, on an hourly basis for a desired time period. Case study showed that the application of this methodology could be used to expediently provide energy simulations while at the same time reproducing the BIM in a more readably three dimensional modeling program. With the aid of an easy to run and easily understood energy simulation methodology, designers will be able to make more energy conscious decisions during the design phase and as changes in design requirements arise.

러시아-우크라이나 전쟁이 진행중인 상황에서 2023년 10월 7일 하마스의 기습공격으로 전쟁이 발발하였다. 이스라엘과 하마스는 2021년에 비슷한 원인과 양상으로 충돌이 있었고 곧바로 평화협정을 맺고 일단락되었다. '인류의 역사는 전쟁의 역사'라고 해도 과언이 아닐 정도로 전쟁은 인류사의 상당 비중을 차지한다. 케네스 월츠에 의하면, 인간의 폭력적이고 이기적인 본성과 국가의 자국 이익 추구의 속성, 그리고 국제체제가 전쟁의 원인으로 동시에 작용한다고 하였다. 본 연구의 목적은 이스라엘-하마스 전쟁의 원인을 케네스 월츠의 3가지 이미지 이론으로 분석하여 시사점을 도출하고 한국의 군사전략에 미치는 함의를 제공하고자 한다

In this study, we conducted a survival analysis on battalion-level commanders(leaders), focusing on infantry battalion defensive operations using the big data of brigade-level KCTC(Korea Combat Training Center) training results. Unlike previous studies, we utilized the brigade-level KCTC training results data for the first time to conduct a survival analysis, and the research subjects were battalion-level commanders(leaders), which can affect the battle. At this time, the battle results were defined, and through cluster analysis, infantry battalions were divided into excellent, average, and insufficient units, and the difference in the survival rate of the commanders was analyzed through the Kaplan-Meier survival analysis. This provided an opportunity to objectively compare the differences between excellent and insufficient units. Subsequently, factors affecting the survival of commanders were derived using the Cox proportional hazard model, and it was possible to confirm the influencing factors from various angles by also using the survival tree model. Significance and limitations confirmed in the research process were presented as policy suggestions and future research directions.

This study was conducted by the questionnaires to 323 undergraduate students in fashion related departments. Questionnaires were designed to ask total 23 questions including possibility of halfway dropouts, establishment of goals, self-improvement, entrance motives, satisfaction ratings of academic subjects, job prospects and path planning, amelioration of ways to instruct, desires for the integrated lessons and intense academic courses, wishes of field project education carrying out tasks, desired lecturers, and others. Results in this research were summarized as follows. To begin with, it was appeared that respondents with possibility of halfway dropouts showed considerable percentage (25.4%) and the reasons left out were various including joining the army, the poor economic conditions in family, a major not corresponding with one's aptitude. Secondly, in the extent of establishing goals and improving oneself, there was the difference between people with possibility of halfway dropouts and people without that, and it was judged that the extent of establishing goals and improving oneself as good parameters could explain halfway omission. Thirdly, the ways to teach for getting classes interesting were to make instruction according to one's capabilities, to progress systematically, and to take lessons with specific goals. Fourth, many respondents answered to want the integrated lessons, intense academic courses, and field project education carrying out tasks. Fifth, an overwhelming majority of respondents hoped instructors with a outstanding ability in business. For improvement of the ways to instruct and the role of professors, it is suggested as follows. First, students are given intelligible lessons focused on fundamental subjects fitted to their levels and also need gradual intense academic courses classified by their way directions and interests. Second, creative and individualized teaching methods depending on the majors and levels are developed to help students have strong interest in schoolwork. Third, professors are constantly to learn practical techniques and skills related to industries in step with the education goals of college. Fourth, it is desirable to adopt instructors with practical business talents rather than theoretical capabilities.

Hwangrong Temple was the center of the Buddhist culture of Silla dynasty. It was built in the 14th year of King Jinheung in Silla dynasty, and completely burnt out when the Mongol Army invaded the Korean peninsula during the reign of King Gojong of Koryeo dynasty. 8-year excavation of the site from 1976 as part of the Gyeongju Tourism Comprehensive Plan revealed many things about the Hwangrongsaji. Recently, a book introduced 'Geumdongnanganpyeon' among relics found in the site, but omitted in the Excavation Report published at that time. Though 'Palgak Geumdongnanganpyeon' has numerical signs 六, 七(six, seven), there was no clear explanation of the signs. Thus, this paper examines it. We can guess, through the remaining iron fragment, that the side of Geumdongnanganpyeon is octagonal, and the width of the side S13 fragment belongs to is about 400mm. The overall form of the face is similar to the Geumdong Palgaktop stored in the Museum of Dongguk University, but, in detail, it is similar to the Zhuanlunzang Pavilion of Longxing Temple and the Sakyamuni Pagoda of Fogong Temple in China. And, numerical signs can be understand to designate the numbers of story and face. The reason why the number might indicate the number of story is that fragments which are presumed to be used for the same purpose contain different measurement values, and the basis of the concept of face can be found in efficiency of manufacturing and manufacturing techniques of artifacts of the time. The two aspects mentioned above cannot be confirmed because of not sufficient relics and related researches. But, the overall form may have been multi-story tower of at least two stories. If more studies in various fields are done in the future, it is expected that the original form will be recovered more accurately.
