Mass customization meets various needs of customers as well as produces various products and service in low cost like mass production. However, low cost and product diversity have conflicting concepts. Therefore, in order to solve this problem, we need standardization methods. In this paper, we suggest a method for determining the product platform which is a set of common parts in a product family. To achieve the method, we used the Contradiction Analysis of TRIZ (Theory of Inventive Problem Solving), Using this approach, we found a model that obtains various products within limited resources and conditions. Also, we suggest another method that increases the flexibility of our method by Design Structure Matrix.

New towns and large multi-family housing complexes are being built in the capital region of Korea, with the goal of creating safe and pedestrian-friendly cities. Traffic accidents in such residential complexes, however, is on the rise, creating social problems. While there have been many previous studies on problems with pedestrian environment; there is a dearth of studies that take design-based approach to ensure safety in pedestrian environment within residential complexes. Therefore, this study aims to prevent traffic accidents by properly planning pedestrian environment within multi-family housing complexes, in addition to emphasizing theories related to planning safer pedestrian environment in general. This study found the following design directions required to improve the design theory of pedestrian safety in multi-family housing complexes: (1) Linking traffic facilities and residential complex spaces in Korea; (2) Considering implementation of United Kingdom road systems; (3) Establishing appropriate objectives for each residential complex based on case study. In response to these findings, the study selected the A84BL complex in Hwaseong Dongtan 2 Complex located in Dongtan-myeon, Hwaseong-si in Gyeonggi Province, Korea. Items that can be implemented, as well as spatial design directions, were discussed with a focus on private vehicles, pedestrians, and service vehicles.

미국사회는 미혼모들의 문제를 개인적 뿐만 아니라 사회적 그리고 국가적 문제로 인식하므로 이들을 위한 다양한 사회복지 정책과 서비스, 그리고 프로그램들을 제공하여 이들이 스스로 자활할 수 있는 토대를 마련하여 왔다. 특히 십대미혼모들은 학교를 중퇴하고 직업을 갖지 못하며 빈곤한 환경에서 아이를 키우기 때문에 심리적 정신적으로 불안한 상태에 있다. 이들에 대한 서비스는 국가적으로 미혼모뿐만 아니라 어린아이들까지도 돌보는 것으로 가정과 사회의 안정을 가져오며 인적자원을 잘 보존하는 것이다. 한국의 경우도 현대화/산업화된 사회로 발전하며 청소년들의 문제가 특히나 십대 미혼모의 문제가 사회적으로 이슈화되고 있다. 따라서 이 연구는 미국의 상황을 분석하고 미국의 복지 정책, 프로그램, 자원봉사자들을 이용한 서비스들을 살펴보고 한국에 적용 가능한 복지프로그램과 지원서비스를 제안하고자 한다. 미국의 미혼모를 위한 대안 학교차원의 교육/직업훈련/부모교육 등과 가족지원프로그램은 미혼모뿐만 아니라 사회와 가족이 모두 혜택을 받을 수 있는 서비스며 프로그램이므로 한국사회에 적용하면 효율적으로 미혼모들의 어려움과 사회문제를 해결 할 수 있다고 본다. 또한 자원봉사의 서비스 체계가 미혼모를 위한 사회복지 프로그램 등에 적극적으로 활용되면 미혼모들은 믿고 따를 수 있는 롤 모델을 갖게 되며 국가적으로는 인력의 활용과 자원 절약의 효과를 기대할 수 있다.

This study examined the retirement adaptation process for middle-aged and elderly couples. Twelve couples who had experienced retirement were recruited by theoretical sampling. Data were collected through in-depth interviews and analyzed through the grounded theory approach of Strauss and Corbin (1998). This study showed the results of 124 concepts, 41 sub-categories and 17 categories indicated through an open coding process. As a paradigm in axial coding, the causal conditions in the adjustment procedures of elderly couples whose spouses are retired were 'retirement preparation,' 'retirement acceptance,' and 'marital satisfaction.' A central phenomenon was 'crisis and conflicts of twilight couples.' The contextual conditions that correspond to this phenomenon were 'psychological separation from adult children,' 'division of household labor,' and 'economic status.' The action/interaction strategies to control the phenomenon were 'recognition of marital relationships,' 'conflicts coping,' 'resolution methods,' and 'self-reflection.' The intervening conditions that facilitate action/interaction strategies were 'attitudes of husbands,' 'mutual awareness of couple,' 'health status,' and 'support systems.' The consequences were 'readaptation of marital relationships,' and 'unresolved conflicts,' and 'trying alone.' This research classified middle-aged and elderly couples' adaptation into three types such as mutual effort, separation & resignation, and conflicts vestige. The findings provide basic information to develop a retirement adaptation program for the middle-aged and elderly.

Purpose: The purpose of this study was to explore the stress-coping process used by elderly people. Method: This study was based on the grounded theory methodology of Strauss & Corbin. The participants were 15 elders selected by theoretical sampling. Over a period of 3 months, in-depth interviews using audiotape recording were used to collect the data. The data were analyzed simultaneously by a constant comparative method in which new data were continuously coded in categories and properties according to Strauss and Corbin's methodology, Result: Stress in elderly people is caused by illness, family conflict, and loss of economic power. Stress occurred in connection with aging and limitation of social activity. The central incidents for stress were fear, alienation and anxiety. It was found that action/interactional strategies of stress-coping behavior were related to social support and mobility disorders. Action/interactional strategies to stress-coping in elderly people were dependent on medical treatment, mind control, participation of social activity, and renunciation of offensive behavior. Stress-coping in elderly people resulted in stability or instability in body and mind. Conclusion: It is suggested that the results of this study may contribute to the development stress-coping strategies for elderly people. There is need to develop social support systems and a positive environment to avoid negative coping strategies.

Objectives : Functional Cerebrospinal Therapy (FCST) is a new physiologic therapeutics developed in Korea as a meridian yinyang balance approach. The theory of yinyang balance has been at the core of health enhancement approach of meridian and acupuncture medicine ever since its start. Methods : Introductory overview of FCST is presented in relation with meridian yinynag balance theory. Results : As the temporomandibular joint (TMJ) and related tissues have direct interconnection with brainstem proprioceptive or motor systems and the face is where all the meridians converge, FCST applies a fine adjustment of the posture of TMJ as a treatment tool for neurologic conditions or meridian imbalances. Conclusions : Highly sophisticated diagnostic and therapeutic techniques to adjust various subset aspects of yinyang balance are developed within FCST, which is supposed to be one of major contributions to natural healing.

We study the structure of an arbitrary graded Lie triple system $\mathfrak{T}$ with restrictions neither on the dimension nor the base field. We show that $\mathfrak{T}$ is of the form $\mathfrak{T}=U+\sum_{j}I_j$ with U a linear subspace of the 1-homogeneous component $\mathfrak{T}_1$ and any $I_j$ a well described graded ideal of $\mathfrak{T}$, satisfying $[I_j,\mathfrak{T},I_k]=0$ if $j{\neq}k$. Under mild conditions, the simplicity of $\mathfrak{T}$ is characterized and it is shown that an arbitrary graded Lie triple system $\mathfrak{T}$ is the direct sum of the family of its minimal graded ideals, each one being a simple graded Lie triple system.

The purpose of this study was to improve the understanding of the essential experience of Separated Families in South and North Korea in a socio-cultural context and to explore their post-separation adjustment process from the perspective of the families. Major findings in this study are summarized as follows. First, 'han' was the central phenomenon that the participants experienced following their separation. Second, the core issue in the process of post-separation adjustment was 'accepting the separation and rearrangement of reality for reunion', and over time the participants went through four stages in their adjustment process: the stage of being overwhelmed, the stage of conflict, the stage of awareness, and the stage of acceptance. Third, the main factors affecting the participants' adjustment were supportive systems, available resources(individual variables) and interaction with other separated families. fourth, four types were observed in the typology of adjustment and reunion of the participants.

Phase-type distributions are the distributions of the time to absorption in finite and absorbing Markov chains. They generalize, while at the same time, retain the tractability of the exponential distributions and their family. They are widely used as stochastic models from queuing theory, reliability, dependability, and forecasting, to computer networks, security, and computational design. The ability to fit phase-type distributions to intractable or empirical distributions is, therefore, highly desirable for many practical purposes. Many methods and tools currently exist for this fitting problem. In this paper, we present the results of our investigation on using orthogonal-distance fitting as a method for fitting phase-type distributions, together with a comparison to the currently existing fitting methods and tools.

We consider the robust control problem for non-minimum phase(NMP) systems with parametric uncertainty. First, a new method that translates such an uncertain NMP system into a interval family of minimum phase(MP) transfer functions followed a time delay term in the form of Pade' approximation is presented. The controller to be proposed consists of a compensator with Smith predictor structure, so that it can compensate the time delay behaviour due to NMP plant. Therein, the main feedback controller for a family of MP plants has been designed by using quantitative feedback theory(QFT) such that satisfies the robust stability against the structured uncertainty. The stability and performance of overall system are examined through an illustrative example.
