현재 통신용 강관전주는 상, 하로 2 분할된 강관을 조립하여 대부분 사용하고 있다. 콘크리트전주에 비해 가볍고, 길이가 짧기 때문에 도심지 등 협소한 지역에서도 시공이 가능하며 특히 소규모 인력으로 시공이 가능하다. 하지만 전주의 단면이 작아 별도의 기초 보강을 하지 않고서는 지반의 지지력이 부족하여 전주가 기울어지거나 전도되는 현상이 빈번히 발생하고 있으며, 또한 운반을 용이하게 하기 위하여 2 분할한 강관의 조립 부분에서의 꺽임 현상이 발생하여 도시 미관을 해치고 있는 실정이다. 통신전주의 안정성을 확보하기 위해서는 전주 자체가 보유한 강도를 발휘할 수 있도록 충분한 지반지지력이 확보되어 있어야 한다. 강관전주의 휨강도 실험 및 현장 지반지지력 실험을 통해 충분한 지반지지력을 확보할 수 있는 공법을 도출해 내고, 현재 강관전주의 지반지지력 보강을 위해 사용하는 콘크리트블록 설치 방식이 아닌 시공 편리성 및 안정성을 개선한 기초콘크리트 방식을 제시하고자 한다.

본 연구는 도시와 농촌거주 결혼이주여성들의 결혼적응도가 삶의 질에 미치는 영향에서 배우자 및 가족지지의 조절효과가 거주지역별로 차이가 있는지 분석하여 결혼이주여성들의 삶의 질을 향상시키기 위해 거주지역 특성에 맞는 중재전략을 마련하는데 기초자료로 활용하고자 시도되었으며, 본 연구결과 결혼적응도와 삶의 질 사이의 영향관계에서 배우자 및 가족지지의 조절효과가 있었고, 도시보다 농촌에서 더욱 중요한 것으로 나타났다. 본 연구결과를 근거로 농촌과 도시의 특성에 맞는 거주지역별 특성을 고려하여 배우자지지, 가족지지를 향상시킬 수 있는 맞춤형 중재전략을 개발하여 적용해 볼 것을 제언한다.

본 연구는 교각운동시 불안정한 지지면과 안정적인 지지면을 제공하여 체간 및 하지의 근 활성도의 변화를 알아보고자 하였다. 이 연구의 대상자는 20대 남, 여 14명이었다. 실험방법은 일반적 교각자세와 다이나믹 에어쿠션을 이용한 교각자세를 실시한 후에 무선 8채널 표면근전도 검사기를 이용하여 체간부의 척추기립근, 복직근, 대퇴의 대퇴직근, 외측 슬괵근, 하퇴부의 전경골근, 비복근 외측두에서 근활성 정도를 측정하였다. 체간부의 척추 기립근, 대퇴이두근, 가자미근은 불안정한 지지면에서 근활성도가 높게 나타났다(p<.05). 따라서, 교각운동에서 불안정한 지지면의 제공은 신체의 배측에 위치한 근육의 활성화를 나타내어, 교각운동시 지지면의 안정성의 변화만으로도근육활성도의 변화가 가능함을 알 수 있었다.

The purpose of this study was to investigate effect of feedback methods and ambulatory assistive aids on accuracy of partial weight bearing in healthy adults. Twenty subjects were recruited and trained to 30% weight bearing of body weight (BW) using 3-point gait crutches and wheeled walker pattern. Dynamic feedback group (n=11) was received dynamic postresponse feedback and static group (n=9) received static feedback. Force plate was used to measure %BW and GAITRite used to measure gait parameters in immediately and after 3 days of training. Immediately after training, there was not significantly at 30%BW target load in dynamic group with crutch gait (p>.05). There were significantly differences in %BW according to feedback methods and ambulatory aids (p<.05). There was not significant difference between immediately and after 3 days of training (p>0.05). There were significantly differences in gait velocity and stance ratio between crutches and wheeled walker gait (p<.05). Thus, it was suggested that if possible, use crutches, training for partial weight bearing via dynamic feedback is necessary.

The purposes of this study were to identify influence of social networks and social support on depression among older women in rural area on agricultural off-season. The sample consisted of 112 women aged 65 years or over who lived in rural areas of Chung-Nam. Some variables related to depression in older women, including depression, social network, social support were measured using reliable instruments. Pathway analysis was used to test the proposed conceptual model designed to explain the direct, indirect and total effect between social networks and social support on depression. Result, direct effect of satisfaction with kin network and instrumental support on depression was found. And indirect effect of network size with kin, satisfaction with kin network on depression was found. Based on these results, it is necessary to develop supportive system to reduce depression and to improve satisfaction with kin network and instrumental support.

The purpose of this study is to examine factors influencing adolescents' suicidal ideation and provide foundational data to reduce adolescents' suicidal ideation and prevent their suicide based on that. According to the research results, there was no significant difference found in demographic characteristics. And depression, stress, and social support exerted significant influence on suicidal ideation. As depression and stress became higher, suicidal ideation increased. When other factors were controlled, suicidal ideation increased if social support was provided less. Based on the study results, the study has made political suggestions as follows: first, regarding the family support system, it is needed to adopt institutional approaches so that they can participate in many different types of education to improve relationship between parents and children. Second, about the school support system, it is necessary to develop programs to form teacher and peer support relations and build the friend support resource system. Third, in terms of the community support system, it is required to build an integrated support system to form diverse local networks.

This study examined the status of and factors associated with drinking experience, smoking experience, and internet addiction among elementary school students. Cross-sectional data were collected by questionnaire from 1,061 children among the fifth and sixth grades in public elementary schools in Gyeonggi province. The prevalence of drinking and smoking experience, internet addiction of participants was 22.7%, 2.9%, and 4.2% respectively. Multiple logistic regressions showed that the likelihood of drinking and smoking experience, and internet addiction was commonly higher with those who was a male and had higher aggression level. The likelihood of drinking experience was lower with those who had higher family support, while was higher with those who had higher friend support. That of internet addiction was lower with having higher friend and teacher support. Prevention strategies to prevent drinking, smoking, and internet addiction among elementary school students should consider student's gender, control aggression, and enhance social support in family and school environments.

Stone column is one of the soft ground improvement method, which can enhance ground conditions such as the settlement reduction and the increasement of bearing capacity with applying the crushed stone instead of sand. In recent, general construction material, sand is in short of supply. Therefore, the bearing capacity improvement by the stone column is considered as the alternative method needed in many cases so the bearing capacity estimation is considered as important point. Nevertheless, adequate estimation methods to predict bearing capacity of stone column considering stone column and improvement effect of ground is not yet prepared. For the analysis of above mentioned points, the behavior of stone column were simulated as numerically on various property cases of crushed stone and surrounded ground. Through the numerical analysis of simulation results, the formula for the bearing capacity estimation of stone column was suggested. This formula was verified by comparing the prediction result of in situ test.

New PHC piles, where short steel pipes are attached to the pile toe, are developed to increase the base load capacity of bored pre-cast piles embedded in weathered rock. In this study, new bored pre-cast piles using the new PHC piles are installed at 7 test sites with different soil conditions, and static and dynamic pile load tests are performed to investigate quantitative characteristics on the base load capacity of new bored pre-cast piles. In addition, based on the static pile load test results, a new empirical equation for estimating the base load capacity of new bored pre-cast piles is proposed. A comparison between predicted and measured base load capacities shows that the proposed empirical equation produces conservative predictions for the new bored pre-cast piles. However, the existing design criterion significantly underestimates the base load capacity of new bored pre-cast piles.

This study was performed to determine the levels of depressive symptoms among community elderlies and to reveal its related factors, specifically aimed at revealing factors such as social support, family support and physical function. The interviews were performed, during the period from April 1st, to June 30th, 2010, to 995 elderlies in Daejeon city. As a results, social support, family support, ADL and IADL was found to be in a positive correlation with depressive symptoms. With the analysis of covariance structure, social support was more influential on the level of depressive symptom than family support and physical function. It was found to have the inter-relational effects that the greater the social support, family support and physical function, the lower the level of depressive symptoms.
