대부분의 함정 전투체계의 교전 시뮬레이션은 필수적으로 운용자(통제관 및 대항군)가 포함될 수밖에 없음으로 인해 시뮬레이션은 실시간 정도의 저속이며, 시뮬레이션 결과도 객관적인 평가가 어렵다. 이러한 문제를 다루기 위해 본 논문에서는 인간 대신 다중 에이전트 시스템을 이용하는 에이전트 기반의 함정전투 M&S 시스템을 제안한다. 에이전트기반 M&S 시스템은 인간의 개입을 배제하고 자율적 추론기능을 제공함으로써 전투체계의 효과도 분석 및 운용전술개발 등께 대한 효과적인 지원을 가능하게 해준다. 본 논문에서는 이를 위하여 첨단 M&S 프레임워크와 자율 에이전트 설계 원칙을 도입함으로써 인간 미개입형 M&S 시스템 설계 개념과 방법론을 제시하였고, 서해교전상의 함정전투 사례연구를 통해 그 타당성을 검증하였다.

Efficient space plans are built upon relations of both human and physical compositions, and the standard of the interaction is basically the human scale. Especially in medical areas, the character of the users within human scale design environment is quite significant. Unlike large hospitals with great plans and scalability performed by experts, mid-sized clinics tend to have limited space, designed by non-specialists who highlight aesthetics over functionality in floor plans which leads to poor quality in medical service. For this reason, this study will include the application of human scale based therapy rooms within the clinic from a physical standpoint and will further analyze and pinpoint any room for improvement to further enable more efficient ergonomic space planning. In this study, theoretically will contemplate over human scale, mid-sized clinic, therapies, and therapists, while the case study will include status of the recent human scale based mid-sized clinic from a physical viewpoint, classification and analysis amongst human and physical compositions chosen by discretion from either a newly opened or a newly re-modeled clinic within the last 2 years, which has 15 beds or more, minimum 3 physical therapists, with more than 5 different therapy facilities in the metropolitan area in order to measure the human scale of therapy rooms in a mid-sized clinic. As a result, the area where improvement can practically be applied is the physical composition, which does not include human scale like human composition factors as therapists and patients, and hence, I suggest the human scale applied efficient medical space plan become the base of this study and look forward to subsequent improvement in the quality of medical services.

Industrialization and development of technology satisfied various humanly needs and lay the basis of numerous benefit and profit. New technologies like these mostly required large amounts of fossil Fuel, Fossil energy depletion rate was increasing rapidly. However, technical development for Human race required absolute sacrifice of the environment. Especially, 'City' which had been focused as stage of human activities, allowed to continue to have fossil energy dependent activities, and it shows in many data that the city is responsible for the 75-80% of the green house gas by human. In order to solve the problem relating climate changes and energy, European countries already made progress studies on many of the low carbon green city and pilot case construction. Especially, Germany, Austria, Holland, Sweden who had been playing leader role on environmental awareness and ecological concept, are actively constructing low carbon green city project based on Ecological city planning scheme. These projects positively utilize planning scheme that limits carbon emission using Urban Metabolism concept. Therefore, throughout this study, I would like to present planning and direction of future domestic low carbon green city by analyzing theories relative theories and best practices in Europe.

In Anthropology, ceremonies which human should pass in lives are difined as ‘Rites of Passage’. Each Rite has its own Clothing style, which is little different from general Clothing in shape, composition, color, meaning, etc. This Study shows composition and characters on Birth Ceremony Clothing through Documents and Survey around Chonnam Area. Survey Area is subdivided into 3 parts : Koksung(A Basin of Sumjin River-Eastern Area of Chonnam), Na-ju( A Basin of Yeongsan River-Western Area of Chonnam), and Kangjin(Southern Area of Chonnam). This Study analyses characters on Baenaet Jogori, 100th-day Clothing and First-birthday Clothing in Chonnam Area. In case of Baenaet Jogori, its shape in Survey is similiar to that of documents. In case of 100th-day Clothing, New Jogori and Baji have been made usually. First-Birthday(called “Dol”) Clothing shows difference between male and female infant. Male clothing consists of Pungcha Baji, Jokki, Magoja, Doltti while Female clothing consists of Pungcha Baji, Chima, Jumoni, and Doltti. In making of infant Clothing, 5-colors(Blue. Red, Yellow, White, Black) which consists of basic color in the Theory of the cosmic dual forces and Shape of Letters such as 壽ㆍ福ㆍ亞ㆍ卍 are used usually. This kind of colors and Shape of letters symbolize longevity and fortune. As a result of study, I find what Ritual Clothing in Birth has many symbolic meaning which reflects life-style culture. This study lay meaning on that deals infant clothings as a kind of Ritual Clothing.

We propose a new method of masking cloud-affected pixels in satellite ocean color imageries such as of GLI. Those pixels, mostly found around cloud pixels or in scattered cloud area, have anomalous features in either in chlorophyll-a estimate or in water reflectance. This artifact is most likely caused by residual error of inter-band registration correction. Our method is to check the pixel-wise 'soundness' of the spectral water reflectance Rw retrieved after the atmospheric correction. First, we define two spectral ratio between water reflectance, IRR1 and IRR2, each defined as RW(B1)/RW (B3) RW (B3) and as RW (B2)/RW(B4) respectively, where $B1{\sim}B4$ stand for 4 consecutive visible bands. We show that an almost linear relation holds over log-scaled IRR1 and IRR2 for shipmeasured RW data of SeaBAM in situ data set and for GLI cloud-free Level 2 sub-scenes. The method we propose is to utilize this nature, identifying those pixels that show significant discrepancy from that relationship. We apply this method to ADEOS-II/GLI ocean color data to evaluate the performance over Level-2 data, which includes different water types such as case 1, turbid case 2 and coccolithophore bloom waters.

Energy consumption has been increased world widely, and the energy retain is one of the most important economic alternatives. These tendencies expand the nuclear power plants not only quantitatively but also qualitatively. Despite of the increasing construction of nuclear power plants and related facilities, every system in main control room(MCR) has been designed and administered solely based on the safety-first principles because of the specificity of nuclear industry. However, recent main control rooms started with the concept that the operators' performance could be optimized though the organic interrelation between human, machine, and environments. Now, it has been recognised in the scope of Ergonomics and Space Design which acknowledge our living spaces as Man-Environment Interface and this change connotes the MCR spaces should be special spaces rather than ordinary spaces. This research investigated domestic and foreign nuclear power plants' MCRs to suggest basic alternatives which can be applied to future MCR. With the review of characteristics of MCR, an integration of interior design, lighting and Ergonomics was explored and classified as types. Futhermore, the classification of environmental characteristics within the relationships between human, machine, and environments was developed through the case analysis of nuclear power plants. The results of this study will provide a basis of space design for system environments that the high level of safety and function are extremely important.

An extensive research was undertaken to study the vibration serviceability of a long-span and light-weight floor subjected to human loading experimentally and numerically. Specifically, heel-drop test was first conducted to capture the floor's natural frequencies and damping ratios, followed by jumping and running tests to obtain the acceleration responses. In addition, numerical simulations considering walking excitation were performed to further evaluate the vibration performance of a multi-panel floor under different loading cases and walking rates. The floor is found to have a high frequency (11.67 Hz) and a low damping ratio (2.32%). The comparison of the test results with the published data from the 1997 AISC Design Guide 11 indicates that the floor exhibits satisfactory vibration perceptibility overall. The study results show that the peak acceleration is affected by the walking path, walking rate, and adjacent structure. A simpler loading case may be considered in design in place of a more complex one.

Poor children are a field of causing of various Issues and become a subject of sympathy, concern and anger, against adult's poor such as sleeper outdoors and unemployed to be made a subject of discussion. This study has theoretically investigated the poverty concept, family trait around poor children. And also for understanding the above status, poverty circumstances have been focused children family and shelter-care children. The conclusions are as follows. First, the family of children head was formed with children under fifteen years of age. It was reported that solo families were 26.4% and living together families with relatives were 64.7%. As status of producing causes, parents death was shown the most rate as 49% and abscondence or missing was 31.9%. Second, In the shelter-care aspect, the highest case is a parents-divorce with 42.5%, while children-head case is just shown 0.5%. Therefore, in a child right viewpoint, it needs more systematical/long-range study on children poverty, and some policies for protecting the poverty-children must be established in social policy.

Pay-for-performance plans are some of widely used human resource practices in many firms, including shipbuilding, for productivity and motivational improvement purposes. Such plans play an important role in industries that are highly labor-intensive, and where effective management of human resources is critical to business operations, such as the shipbuilding industry. Those practices can have large impact on employee performance and ultimately company competitiveness. Research studies that show how such incentive plans improve productivity and reported pattern of adoption by firms have spurred the use and adoption in many firms. However, there are also researchers who point out that there are negative consequences to using incentive plans. Therefore it is important for companies to carefully consider the practices they use. In this paper, I discuss research findings that support the practices and critical viewpoints related to pay-for-performance plans. Research findings from Korean literature are, then, discussed. The shipbuilding industry is chosen because proper human resource management is critical in reducing turnover and increasing employee satisfaction. Through a shipbuilding company case, problems related to using pay-for-performance incentive plans and how they affect work-related issues of employee morale, cooperation, and teamwork will be discussed. While positive aspects have been emphasized to drive greater adoption among firms, the resulting consequences of the pay plans need to be seriously considered and improvements upon the plans made by firms. Improvement suggestions are discussed in the conclusions and implications.

The friction behavior of human skin is determined by the complex interplay of the material and surface properties of the skin, as well as the contacting material, and strongly depends on the contact parameters (e.g., pressure and sliding velocity) and the presence of substances such as water, sweat, or skin surface lipids at the interface. Including a study on the effect of a surface's physical roughness for skin sliding over the surface, various studies have been conducted to understand human tactile sensibility. However, to investigate products in relation to human tactile sensibility, more objective research is needed. This study performed sliding experiments between the skin and the surfaces of phone cases to understand how the texture, friction, and stick-slip characteristics are related. Eight phone case surfaces with different topologies and chemical (or mechanical) compatibilities with skin were prepared and tested multiple times.
