This study shows the floor plan types and the space composition of multi-used toilets in public-toilets of Choongchung-Do. The areas of multi-used toilets are various from 4.8m2 to 10.5m2 And there Is usually one multi-used toilet in one public-toilet, but some public-toilets have two multi-used toilets. Multi-used toilets have several equipments such as toilet stool, urinal, washstand, change diaper, chair for baby-care, toilet stool for child, urinal for child, so on. All the multi-used toilets have toilet stool and washstand, but urinal and change diaper were used restrictively, and chair for baby-care, toilet stool for child, urinal for child were used in few cases. There are six types how the multi-used toilets are located in public-toilets, five types of multi-used toilet forms, and five types how the equipments are installed in multi-used toilets. The dotted blocks are installed partially in line type, and partially in spot type. But some cases, there was no installation of dotted block. Auto-sliding door were usually applicated, and some other types of door system were used restrictively. This study offers not only the present conditions, but also the appropriate planning directions of the multi-used toilets.

Increased multi-cultural families over the recent decade have led to more studies on the current situations and problems they face. Fathers in multi-cultural families are supporters who can help their migrant wives adapt their new surroundings; however, it is difficult to find studies on them as their roles as fathers in multi-cultural families have been overlooked. This study develops educational programs for fathers in multi-cultural families and analyzes the effect of the educational programs. The educational program development for fathers in multi-cultural families was based on consideration of related articles, studies, and reports. The effect analysis for the educational program for fathers in multi-cultural families was performed through the investigation of 'self-esteem' and 'parent self-confidence' about educated fathers in multi-cultural families. The educational program for fathers in multi-cultural families was composed of 5 themes which can improve their self-esteem, understand the father's role and function, learn the skills of playing and conversation with their children and express the father's thoughts for his own family using positive methods. We educated 12 fathers in multi-cultural families through the development of the program over 5 weeks to verify the effect of educational programs for fathers in multi-cultural families. The results showed the following : The level of father's self-esteem in multi-cultural family increased 124% and the level of parent self-confidence increased 141%. In conclusion, the educational effect for fathers in multi-cultural family exists and their desire for a successful multi-cultural family increased through the educational programs.

본 연구에서 R410A를 사용하는 멀티에어컨 시스템의 성능(성능계수, 용량, 소비전력 등)을 정상 상태에서 모사할 수 있는 Multi_Cycle이라 명명된 컴퓨터 모사 프로그램을 개발하였다. 컴퓨터 시뮬레이션 프로그램을 검증하기 위해서 일련의 사례 연구를 수행하였으며, 이에 대해서 설명하였다. Mulli_Cycle은 실내기, 실외기, 압축기와 팽창 밸브 모사를 위한 부프로그램 및 냉매와 습공기의 열역학적 물성치와 전달 물성치 예측을 위한 부프로그램으로 구성되어있다. 멀티에어컨 사이클을 구성하고 있는 각 유닛의 복잡한 조자조건과 다양한 종류의 냉매를 고려해야 하는 멀티에어컨의 성능 분석시 Multi_Cycle의 사용은 많은 도움이 될 것이다. 나아가, Multi_Cycle은 멀티에어컨 시스템을 최적화하고, 경제적이고 효율적인 운전 조건을 확립하는데 매우 유용한 도구가 될 수 있을 것이다. Multi_Cycle의 주시뮬레이션 코드는 Digital Visual Fortran으로 프로그램 되었으며 그래픽 사용자 인터페이스(GUI)는 Visual Basic으로 프로그램 되었다.

A novel variant of full multi-modulation applications to diode-clamped and cascade multilevel inverter-termed single carrier multi-modulation is presented. The proposed PWM-technique is advantageous for its simple implementation. The correlation between multi-carrier and single-carrier multi-modulations is deduced. For the PWM methods, a mathematical model of voltage source inverter and general algorithm for the multi-modulating modulator are proposed. The theory is demonstrated by simulation results

In the current paper, the intuitionistic fuzzy normed space version of Hyers-Ulam stability for multi-additive, multi-cubic and multi-additive-cubic mappings by using a fixed point method are studied. Moreover, a few corollaries corresponding to some known stability and hyperstability outcomes in intuitionistic fuzzy normed space are presented.

We have developed a Monte Carlo (MC) simulator for electron beam lithography in multi-layer resists and multi-layer substrates in order to fabricate and develop high-speed PHEMT devices for millimeter- wave applications. For the deposited energy calculation to multi-layer resists by electron beam in MC simulation, we modeled newly for multi-layer resists and heterogeneous multi-layer substrates. Using this model, we simulated T-gate or r-gate fabrication process in PHEMT device and showed our results with SEM observations.

In this study, the effect of multi-step purification or functionalization on physicochemical properties of multi-walled carbon nanotubes (MWNTs)/epoxy (EP) nanocomposites was investigated. The nanocomposites containing multi-step purified MWNTs showed a stronger influence on $T_g$ and increased in mechanical properties in comparison to nanocomposites containing the same amount of only purified MWNTs. Consequently, the multi-step purification of MWNTs led to an improvement of thermomechanical properties of nanocomposites, resulting from improving the intermolecular interaction of MWNTs in epoxy matrix resins.

This paper deals with a design problem of simulation for MIME (multi indenture and multi echelon) with lateral transshipment. Especially, we consider lateral transshipments in case that (S-1, S) ordering policy is used in multi echelon repair system. Some rules for ordering spare parts in lateral transshipments between the lowest-level units are studied and are implemented by an activity diagram in object-oriented method. By numerical examples, we compare regular (S-1, S) ordering policy and (S-1, S) policy with lateral transshipment.

본 논문에서는 다중경로 페이딩 환경에서 하이브리드 SC/MRC-Lc/L 다이버시티 수신기법을 이용하여 Multi-Carrier DS-CDMA 시스템의 성능 개선을 알아보고, 광대역 DS-CDMA 시스템과 비교, 분석하였다. 결과적으로 Multi-Carrier DS-CDMA 시스템에서 부분대역간섭에 대한 영향은 성능 열화정도가 전체 주파수 대역 중 일부대역에서 만 받았다. 또한, 하이브이드 SC/MRC-Lc/L 다이버시티 수신 시 Multi-Carrier DS-CDMA 시스템은 입력 다이버시티 가지의 수를 적절히 선택함으로서 시스템의 복잡성과 성능 대 비용을 결정할 수 있다.

Multi-radio multi-channel Wireless Mesh Network requires an effective management policy to control the assignment of channels to each radio. We concentrated our investigation on modeling method and solution to find a dynamic channel assignment scheme that is adapted to change of network traffic. Multi-path routing scheme was chosen to overwhelm the unreliability of wireless link. For a particular traffic state, our optimization model found a specific traffic distribution over multi-path and a channel assignment scheme that maximizes the overall network throughput. We developed a simple heuristic method for channel assignment by gradually removing clique load to obtain higher throughput. We also presented numerical examples and discussion of our models in comparison with existing research.
