In this paper, It was describe the processes of development of HiFi speaker system. Woofer and tweeter were fabricated by unskilled students and their 1.5 parameters were identified by known mass method. Based on T-S parameters port enclosure was designed and built by means of software. Acoustic radiation phenomena of port enclosure were simulated and compared to test result. Acoustic pressure difference between lower frequency and higher frequency was flattened by adopting optimal crossover network. Finally, built HiFi speaker system was showed good sound quality and sound pressure and electrical impedance was well agreed with test results each other.

본 연구는 노인들의 주택개조 의지를 측정할 수 있는 도구를 개발하고 그 타당성을 규명하는 것을 목적으로 한다. 본 연구는 계획적 행위이론 모형을 토대로 한 방법론적 연구로, 사전조사를 실시하여 26개의 예비항목을 마련하였다. 개발된 항목의 내용타당도 검정을 위한 1차 조사와 탐색적 요인분석을 통한 구성타당도 검정 및 내적신뢰도 검정을 위한 2차 조사를 순차적으로 실시하였으며, 그 결과는 다음과 같다. 첫째, 전문가를 대상으로 내용타당도 검정을 통해 사전조사에서 개발된 26개 항목 중 일부가 제외되거나 병합되어 총 22개의 항목으로 재조정되었다. 둘째, 쇠퇴지역에 거주하는 만 65세 이상 여성 노인을 대상으로 도구의 구성타당도 검정하여 공통성이나 고유값이 부적합한 것으로 판단된 항목들을 제외하고 총 14개의 항목이 5개의 요인으로 재구성되었다. 이는 총 72.5% 수준의 설명력을 가지고 있었으며, 내적신뢰도 또한 0.75로 신뢰할만한 수준인 것으로 나타났다. 이러한 본 연구는 공공차원에서 쇠퇴지역의 물리적 환경을 개선함에 있어 주택 소유자의 개조의지를 정량화하여 객관적으로 파악할 수 있게 함으로써 지역의 원활한 환경 재생을 도모하는데 기여할 수 있을 것으로 예상된다.

휠체어를 사용하는 장애인은 주거 환경에서 접근성이 부족하여 일상생활활동에 어려움을 겪는다. 다양한 스마트 기술을 이용한 스마트홈은 휠체어 사용 장애인의 일상생활활동에 있어 접근성을 높여줄 수 있다. 본 연구에서는 휠체어를 사용하는 장애인을 위해 스마트홈을 구축하였고, 구축된 스마트홈에 대한 사용성평가를 실시하였다. 사용성평가는 시나리오기반사용경험평가, 도구적 일상생활활동평가, 그리고 심층설문방법을 사용하였다. 지역사회 거주 휠체어 사용 장애인 3명을 대상으로 스마트홈 사용성평가를 실시한 결과, 기존 거주지에 비해 구축된 스마트홈의 사용성이 더 높은 것으로 나타났다. 하지만 심층설문 결과, 스마트홈 내부의 부분적인 개선 요구사항 또한 도출되었다. 본 연구를 통해 스마트홈 구축 시 휠체어 사용 장애인의 주거환경 구축에 고려해야 하는 다양한 요소들을 확인할 수 있었다.

This study investigates residents' living satisfaction with high-rise, mixed-use apartments built in the structures of reinforced concrete construction(RC) and with steel framed, reinforced concrete construction(SRC). The following study results were obtained: 1) Residents expressed below average satisfaction (below 3.0) with the common-area landscape and environmentally-friendly factors, children's playground and its facilities, community service for residents' by the management offices and utility plan. 2) According to the satisfaction of sound environment, residents of the SRC group expressed above average satisfaction. It can be concluded that noise problems around the residential area of the SRC group was well solved in this study. However, the residents of the SRC group expressed low satisfaction with the freshness of indoor air, humidity, and smell in the living quarters. 3) High-rise, mixed-use apartments should accommodate a familial life cycle, be designed as an environmentally friendly resting place in harmony with city life, and provide various communal programs for residents.

The purpose of this study is to examine the relationships among role conflict coping strategy and psychological distress of dual-career wives. In order to achieve the study purpose the theoretical model of this study was built on the basis of relevant theories and previous studies, Especially it was influenced by the ABCX model of family stress proposed by Hill, Data were collected from 229 dual-career wives such as professors doctors lawyers teachers pharmacists and nurses. The results were as follows: 1. Role conflict was negatively correlated to self-esteem and positively correlated to psychological distress. 2) in terms of a main effect coping strategy was positively correlated to self-esteem and negatively correlated to psychological distress. 3) In terms of interaction effect coping strategy did not show any significant effect against the negative impacts of role conflict on self-esteem and it on the whole did not whole a significant effect against the positive impacts of role conflict of psychological distress.

This paper designs and implements the 2 plug type standby power control outlet based on IEEE 802.15.4 using Zigbee and IPv6 network in order to reduce the standby power to the user. The standby power control system is consisted of direct power and standby power plug. Also this system can communicate bidirectionally in wireless because built-in wireless communication modules. One gateway is linked with many standby power control outlet in wireless. Each standby power control outlet executes the operation needed in power control independently. Also each standby power control outlet has its own power can be detected in real time independently of the power can be controlled.

Purpose: This study was attempted to illuminate danger signals through an extensive analysis of factors influencing adolescents' illicit drug use. On this basis, it built predictive factors of adolescents' illicit drug use. Method: A questionnaire was distributed to 1,238 subjects living in Seoul, and of them 1,082 answers were analyzed using the SAS 8.2 program. Also logistic regression analysis was conducted based on the stepwise selection method for constructing the predictive factors. Results: The findings of this study are as follows. Individual-related factors were psycho-somatic symptoms, self-esteem, fortune delinquent experience, and sexual-violence delinquent experience. Home-related factors were insincerity, threatening and the assessment of the parent (rearer)-adolescent communication type. Society-related factors were affection of friends and friends' attitude toward delinquency. Conclusion: These findings of this study suggest that a broad intervention program should be provided to nurture wholesome youth culture related to illicit drug use. It is also recommended that a variety of individual, home and society-related programs should be developed for drug users.

This study attempts to examine the average number of stored items of apartment residents composed of 4 family members and to compare the quantitative differences of the stored items according to the apartment size and the stage of life-cycle. The finding shows that the number of items stored in apartments increases as the size of apartments and the stag of life-cycle of husband and wife living in the apartments of more than 180$m^2$ increase approcimately twice, compared to those in the apartments of less than 83$m^2$. Therefore, the storage space in apartments should be designed more effectively considering the change of the stored items in relation to of the apartment size and their stage of life-cycle. This study suggests the specific design of the built-in closets for clothings, sheets, accessories and shoes based on the number of the items.
