OBJECTIVES: This study aimed to investigate the association between levels of physical activity (PA) and low handgrip strength in Korean adults. METHODS: Our cross-sectional study design included 24,109 Korean adults older than 19 years of age who participated in the Korea National Health and Nutrition Examination Survey 2014–2019. Low handgrip strength is described as hand strength less than the cut-off value of the 20th percentile of handgrip strength from a healthy population in each gender and age group. PA was categorized into three levels (inactive, active, and highly active) according to the World Health Organization’s global recommendations on PA for health. Multivariable logistic regression analysis was used to examine the association between levels of PA and low handgrip strength. RESULTS: Odds ratios (ORs) for low handgrip strength were significantly higher in middle-aged women who were active (adjusted odds ratio [aOR], 1.40; 95% confidence interval [CI], 1.15 to 1.69) and inactive (aOR, 1.47; 95% CI, 1.23 to 1.76) than in those highly active in walking exercise. Most of older people had significantly higher ORs for low handgrip strength in active compared to highly active in the context of aerobic, muscle strengthening, and walking exercise. CONCLUSIONS: Walking exercise was associated with a lower risk of sarcopenia in middle-aged women and older individuals. However, further studies are necessary to confirm the causal relationship between levels of PA and low handgrip strength.

Incentive systems provide a means by which trade-offs can be carried out between the community and developer. Unlike other flexible zoning techniques, the terms of the trade-offs are usually stated in detail in the zoning ordinance. Incentive systems allow the relaxation of certain zoning requirements in exchange for the provision of specified amenities that benefit the public. This study looks into four cases which are applied on incentive systems.

As public design has been more actively introduced in Korean society for the last few years, recently, the works of renowned global architects and designers - Urban Folly - have been installed in Gwangju as well. But, although the public design installation in Gwangju is in the early stage, many people are suggesting that we should measure the direct effect of introduction of urban design on city image enhancement or urban regeneration from the perspective of residents, effective participants in the project, as substantial costs will be invested in about 100 installments in the future in Gwangju. Therefore, the result of analysis based on such necessity is as follows. First, the result of multiple regression analysis of the effect of Gwangju Urban Folly public design on city brand image shows that there is significant correlation among cultural, environmental, recreational, and aesthetic images. Second, the result of multiple regression analysis on the effect of Gwangju Urban Folly public design on urban regeneration shows that there is partly significant correlation among environmental, social, and economic aspects. Therefore, this study made suggestions on the strategic improvement that can be applied to urban regeneration of Gwangju based on the basic data.

This investigation addresses a necessity of industrial use of regional resources on the basis that the local and regional development should be a top priority for the balanced national development. Accordingly, this study focuses on how regional resources proper to these native districts has been industrialized and what parts the main participatory agents(public sectors and private sectors) have played in the process of regional industrialization. For this, a Japanese apricot industry of Gwangyang, on the South of Jeola Province, and a bamboo industry of Damyang, on the south of Gwangju, respectively, were investigated and analyzed through the qualitative analysis method. Through the case study, the main participatory agents' roles in the success of regional industrialization are as follows: Firstly, in the case of Research and Development, a leading role of public sectors is much required because the pubic sectors can make the support of research funds or the practical use of research workers available. Secondly, in the case of production, the private sectors should play their leading part, while the public sectors need to cater to free concession of state-owned/public lands or administrative and financial incentives. Thirdly, in the case of marketing, the private sectors should perform the active marketings such as the establishment of distribution companies and the practical use of the existing distribution networks. On the other hand, the public sectors will have to perform the marketing supply including external public relations and promotion activities. In conclusion, only in collaboration with the public and private sectors can the regional industrialization make progress.

본 연구는 택지개발사업지구에서 조성되는 보행자전용도로가 적정하게 이용되고 있는지를 파악하고, 이를 토대로 향후 보행자전용도로 계획에 필요한 시사점을 제시하는 것이 목적이다. 이를 위하여 광주광역시상무택지개발사업지구를 사례대상지로 선정하고 보행량 조사결과를 토대로 단계적 회귀분석을 실시하였다. 현황조사 및 분석결과를 정리하면, 첫째, 보행자전용도로 활성화에 영향을 미치는 가장 중요한 요인은 보행자전용도로에 접하고 있는 건축물의 출입구 방향인 것으로 분석되었다. 따라서 향후 보행자전용도로 활성화를 위해서는 보행자전용도로변 출입구 설치 의무화 및 건축물 파사드에 대한 고려가 있어야 한다. 둘째, 보행자전용도로에 접하고 있는 건축물 용도가 중요한 변수로 도출되었다. 보행유발용도의 적극적 도입과 보행미유발용도(숙박시설 등)에 대한 입지제한 등이 이루어져야 한다. 셋째, 보행자전용도로간 연속성 확보가 활성화에 영향을 미치는 요인으로 분석되었다. 이를 위해서는 개발초기 입체교차로의 적극적 설치나 평면교차로의 설치가 이루어져야 한다. This investigation aims to examine whether there is currently the proper use of pedestrian malls created in the Land Development Project areas and to come up with some suggestions for the upcoming plan to build them. The Project areas were designated as the subject of a case study to this end and, on the basis of the findings on the pedestrian movement, Stepwise Regression Analysis was performed. These can be summed up as follows. Firstly, the most important factor which had a decisive effect on the activation of pedestrian malls turned out to be the directions of the exits to the buildings adjoining the pedestrian walkways. Hence, careful consideration should be given to the facade of buildings and the obligation to install the exits to the pedestrian malls for the activation of the pedestrian walkways. Secondly, according to the findings, the use of the buildings adjoining the pedestrian malls could be a second-mostimportant variable. The introduction of the facilities that encourage walking and the location restriction on the facilities(accommodation facilities) that do not encourage walking should be done aggressively. Thirdly, securing the continuity between the pedestrian malls could affect the reinvigoration of the pedestrian malls. To achieve this, the crosswalks should be actively built in the early stage of development.

The hybrid phase shifting device is consist of general phase shifter in sub-array and the true time delay inter sub-array. This configuration for phased shifting can be efficiently improved the beam squint according to frequencies. However, when an appropriate array configuration is not selected, a gain variation of main lobe for a phased array antenna is occurred. In order to solve these problems, a simplified formula for constructing efficient array based on the system design requirements, such as the fractional bandwidth, the maximum beam steering angle, and limit criterion of the gain variation, was presented. 복합 위상천이기 구성은 배열안테나를 부 배열로 구성한 후, 부 배열 내부에는 일반적인 위상천이기를 사용하고, 부 배열 단위에는 실시간 지연 위상천이기를 사용하는 구성이다. 상기 구성은 빔 편이 현상을 효율적으로 개선할 수 있으나, 배열 구성이 적절하지 않으면 위상배열안테나 주 빔의 주파수 별 이득 편차가 발생하게 된다. 이와 같은 문제를 해소하기 위해 시스템 설계 주요 요구사항인 비 대역폭, 최대 빔 조향 각도 그리고 최대 이득 편차 제한 기준을 기반으로 효율적인 배열을 구성할 수 있는 간소화된 수식을 제시하였다.

With respect to the growth and development of innocity from improvements in leisure environments, this research examines the factors that affect the level of satisfaction of innocity leisure environments to propose political implications. In order to do so, 43 leisure activities were chosen, and the level of importance of those activities to the residents prior to moving to the innocity was compared to the level of satisfaction the residents felt regarding the activities after moving. As a result, 13 activities, including literature attendance, had greater levels of satisfaction after moving than the levels of importance prior to moving. The rest (30) activities showed the opposite results. We deduced the factors that affect the level of satisfaction by performing logistic regression analysis on 3 dependent variables. As a result, the static and passive leisure activities had higher satisfactory levels, whereas the dynamic and active had lower satisfactory levels. Thus, innocity must develop culture facilities quickly, expand exercise facilities to support sports activties, and promote tourism by improving and networking with tourist attractions in order to improve future satisfactory levels of leisure activities. 본 연구는 혁신도시 여가환경 개선이 혁신도시의 발전과 성장에 기여한다는 측면에서, 혁신도시 여가활동 만족도에 영향을 미치는 요인을 분석하고 이를 통해 정책적 시사점을 제시하고자 하였다. 이를 위하여 43개 여가활동을 선정하고 이를 대상으로 혁신도시로의 이주 전 중요도와 이주 후 만족도를 비교분석하였다. 이주 전 중요도에 비해 이주 후 만족도가 더 높은 여가활동은 문학행사 참여 등 13개 여가활동으로 조사되었다. 나머지 30개 여가활동은 중요도에 비해 만족도가 낮은 것으로 조사되었다. IPA분석결과, 문화예술관람활동과 사회 및 기타여가활동이 중요도는 높으나 만족도가 낮은 것으로 분석되었다. 전반적인 만족도(3개 문항)를 종속변수로 하여 로지스틱 회귀분석을 통해 여가활동 만족도에 영향을 미치는 요인을 도출하였다. 전반적으로 정적인 여가활동들은 만족도에 유의한 반면, 동적인 여가활동들은 만족도에 영향을 미치지 못하는 것으로 분석되었다. 향후 혁신도시 여가활동 만족도를 높이기 위하여 동적여가활동이 가능한 문화시설용지의 조속한 개발, 스포츠참여활동이 가능하기 위한 운동시설 확충, 주변 관광지와의 네트워크 강화를 통한 관광활동 활성화 등의 정책적 제안을 하였다.
