The purpose of this study was to provide the basic data required for the development and operation of high-quality education programs for newly married couples. The subjects were 60 education programs for newly married couples that were performed by 30 Healthy Family Support Centers in Seoul and the Gyeonggi area. The collected data were analyzed by applying appropriateness, efficiency, and effectiveness on the basis of program plan, execution, and evaluation. The results were as follows. First, the appropriateness of the program plans was no center that performed need survey. As for program advertisement, on-line, off-line, and person -to-person advertisements were used. Second, the education goals and contents were classified according to healthy family life, the essence of the marriage, gender equality, conflict management, problem prevention, relationship improvement, understanding of mutual similarities or differences, financial plan and management, and parenting. Each session lasted 2 hours, and the total number of program hours was 5 to 6 hours. The education methods were activities, lectures, and discussions.

We present a noble method to determine BH mass of many AGNs directly through reverberation mapping using a small telescope with wide-field of view. In 2017 August we installed five medium-band filters to a 0.25m diameter $5deg^2$ FOV telescope at the McDonald observatory. The width of these filters (FWHM ~ 50nm) are matched to the broad line width of type-1 AGNs at various redshifts. From recently obtained data, about r ~ 19 magnitude AGNs can be detected in line component with 150s exposure. With this magnitude limit, about 20~30 AGNs can be studied in one field. We plan to carry out at one day cadence observation over 20~30 fields, enabling us to monitor up to ~1000 AGNs over a wide range of variability. This poster presents out plan and early results from test observation.

The display market has been replaced by the FPD (Flat Panel Display) from the CRT (Cathode-Ray Tube) since the late 1990s. In the FPD production line, the most equipment has high price. Thus, when the equipment has multi-function, the repetitive process is arranged for the equipment. However, such disposition of equipment results in more complicated process flow owing to repetitive operations. This reduces the production capacity and increases lead-time in turn. In this paper, we develop an AutoMod simulation system that derives to information about the quantity, production lead-time, utilities of facilities, and occupation rates of racks. In this simulation system, we consider the situation where the equipment might be broken and suspended randomly. For the developed system, we first evaluate a production plan with current layout and then, propose a revised alternative plan. Using the same simulation scheme, we investigate comparing the production quantity and lead-time with the two plans. In addition, for a proposed alternative, we try to forecast the most adequate rule between the two job dispatching rules which are FOR (Fewest Operation Remaining) and FCFS (First Come First Serve) through simulation.

This paper describes a method for generating an initial hull form by using form parameters. As a mathematical representation of curves, B-spline curves are used as well as the polynomials used by Durand et al. The five basic control curves and the centerline contour are defined to give the boundary conditions for body plan by using above mentioned mathematical models. From these curves body plan is determined. Two additional curves which are concerned the position of matching point between the cylindrical form and the water line are proposed to get the preliminary faired water lines.

B2C 쇼핑몰 시스템의 경우 사용자 인터페이스에 관련된 부분에서만 차이를 보일 뿐 시스템의 기능적인 요구사항과 아키텍처는 유사하며 재사용 가능한 컴포넌트나 COTS 제품을 사용하여 시스템의 많은 부분을 구축할 수 있다. 따라서 쇼핑몰 시스템 구축 시 매번 각 기능들을 설계하고 구현하는 것은 중복 투자를 하는 것과 같다. 이에 본 논문에서는 B2C 소핑몰 시스템의 공통 요구사항을 기반으로 B2C 쇼핑몰 시스템 구축을 위한 프로덕트 라인을 제시한다. 쇼핑몰 시스템 구축에 프로덕트 라인을 적용한다면 중복 투자를 줄이고 미리 준비한 COTS 제품이나 컴포넌트를 사용하여 좋은 품질의 시스템을 빠르게 구축할 수 있다. B2C 쇼핑몰 시스템의 프로덕트 라인을 제시하기 위해 프로덕트 라인의 Core Asset Development 프로세스를 수행하여 쇼핑몰 시스템에 특화된 Product Line Scope, Core Assets, Production Plane을 정의하였다. B2C 쇼핑몰 시스템의 Product Lien Scope는 웹 상에서 물건 판매, 주문 정보 접수, 고객 정보 관리 등의 공통점과 가격의 고정 여부, 검색 등 기타 기능, 공동구매 기능 등의 차이점으로 정의할 수 있다.

First phase section of line 9 which had been constructed by first private capitalization business of Seoul city was opened on July 24, 2009. There are 25 stations of 25.5km operation distance between Gaehwa and Sinnonhyeon, running regular and express trains on the same track. The number of daily passenger demand has risen to above 200thousand passengers with record above 90% of anticipatied transport demand in 2010. The construction of second phase section(Sinnonhyeon~Bohoon Hospital : 14km, 13 stations) is currently under construction for opening in 2016. This study aims to suggest optimal operating patterns taking into consideration theoretical operating headways for regular and express trains, demand of rolling stocks mainly analyzed on record of first phase demand of line 9 and anticipated transport demand of second phase basic plan.

Turnout is a mechanical installation enabling railway trains to be guided from one track to another at a railway junction. A movable nose crossing frog is a device used at a railway turnout to eliminate the gap at the common crossing (High manganese, block, assembly crossing)which can cause impact damage, noise and vibration. Our government has a plan speed up of conventional line to 250km/h semi-high speed. We had already developed flexible turnout with fixed crossing(High manganese) and SFC fastening system can cover in the semi-high speed line In this study is about development of the movable nose crossing turnout available Semi-high speed line on concrete track. This paper describes about geometry, attack angle, bending stress at the nose, switching force, safety of continuous welded long rails. This movable nose crossing turnout is expected greatly increases passing speed of turnout in national railway.

The aim of this paper is to find an adequate method to study declination in Korean. In previous studies of declination in Korean, maximum and minimum pitch values in an accentual phrase were measured. But this method is inadequate when an accentual phrase is located at the intonational phrase. So in order to exclude the final tone of an intonational phrase, we propose to measure pitch values of the first and second tone in an accentual phrase when the tonal pattern of the accentual phrase is 'LHLH'. In this case, the line that connects every first tone of an accentual phrase is the baseline, and the line that connects every second tone of an accentual phrase is the topline. By a comparison of declination between focused and neutral utterances, we will show that the topline of declination is more direct to the speaker's plan than the baseline.
