Objective To provide the off -loading knee brace was designed relief for the pain associated with osteoarthritis by reduce loads on the degenerative compartment of the knee. This study examined the eff ects of the off -loading knee brace on activation of femoral muscles during squatting, slow and fast walking exercise in healthy young individuals. Method Ten healthy male subjects without a history of knee pain were recruited. Each subject was asked to do squatting, slow and fast walking exercises with a brace secured to the dominant leg. The same exercises were repeated without the brace. Surface electromyographic (sEMG) data was collected from the vastus medialis oblique (VMO), vastus lateralis (VL) and biceps femoris (BF) muscles from the dominant side of the leg. All dynamic root mean squre (RMS) values of sEMG were standardized to static RMS values of the maximal isometric contraction and expressed as a percentage of maximal activity. Results We found that VMO activity was signifi cantly decreased with application of the off -loading knee brace during squatting and fast walking exercise. However there were no signifi cant diff erences in VMO activity with application of the off -loading knee brace during slow walking exercise. Conclusion These results suggest that the external moment of the brace which effectively stabilized the patella in the movement in which the knee joints become relatively unstable. Th e brace could be useful in the short term,but for long-term use, weakening of the VMO is predicted. Therefore the program of selective muscular strength strengthening for the VMO should be emphasized.

연구의 목적은 아동평가 중 관찰의 유형과 기능에 대해 알아보고자 하는 것이다. 다른 분야와 마찬가지로 아동의 평가에는 관찰, 면담, 표준화된 평가 방식들이 다양하게 이용된다. 감각통합 치료접근을 사용하는 치료사들의 경우, 아동 평가 중 특히 초기평가에서 기본적으로 관찰법을 이용한다. 명확한 관찰은 평가의 신뢰성과 타당성을 높이는 근간이 된다. 따라서 관찰의 기본적인 방법들과 요소에 대해 알아봄으로써, 향후 치료사의 관찰능력을 제고하는데 활용할 수 있을 것이다. The purpose of this study is to investigate the types and functions of observations at the stage of child assessment. We can use various methods of evaluation. It includes observation, interview, and standardized tests. Most of occupational therapist using sensory integrative approach usually evaluate their clients based on observations especially in the period of initial assessment. The accurate observation is closely connected with reliability and validity of the assessment. Here present some types of observation and the things we should check in ordinary observing moments. It will be considerable aspect when we study how to improve observation ability of the therapists in the future.

In order to effectively manage the reservoir, reservoir water quality management should be based on physicochemical and configurational characteristics. In this research, correlation between factors affecting the reservoir water quality was examined. Chl-a and COD shows the highest positive correlation. Chl-a and T-P also has a high positive correlation, however Chl-a and T-N show lower correlation relatively. Even though T-N is an important factor for phytoplankton growth which increase Chl-a concentration, corelation of Ch1-a and T-N shows that enough nitrogen in the reservoir isn't no longer limiting factor. The age of reservoir can cause of increasing COD and SS. Embankment height and elevation of reservoirs shows strong negative correlation to water quality. That means reservoir which is higher embankment height and locate in higher elevations is less contaminated. Regression expression was derived with Chl-a and water quality parameters, and height of reservoir. Finally Chl-a was simulated using regression expression and it was a good approach to predict the Chl-a concentration.

The 21 livestock farms considering future installation of biogas systems were studied. These farms were examined how to raise the livestock, to treat manure, to operate facility with respect to manure characteristics. The 15 farms out of 21 farms have applied to the marine dumping and consignment treatment for treating manure and even farms which have equipped liquid fertilizing system have less capacity facility than legal standards. Characteristics of manure were affected by the scale of swine barn, clean water usage, frequency of cleaning, cleaning method, feces-urine separating method, etc. Retention time in storage (over 20 days) has resulted in lower concentration of organic matter which could reduce biogas production. This indicates that systematic barn management system is required. Inhibition tests showed that disinfectant and citric acid did not affected digestion rates at 10 times higher concentration than recommendation. However hypochlorous acid is likely to affect the anaerobic microbial activity.

This study was carried out to evaluation of biomass generation mechanisms and to propose the estimation method of biomass generation. Agricultural by-product biomass is generated during crops cultivation and after harvest. However these are not uniformly generated yearly and these depending on the seasons. For planning of biomass utilization, accurate information of the biomass resources is needed, especially characteristic and productivity of biomass are necessary. Agricultural by-product biomass are generated in a wide area being scattered and it is one of the major reason why agricultural biomass utilization is not activated compared with other waste biomass. In this study, estimation and evaluation biomass generation is achieved in specific spatial and temporal boundary, A-city in Gyeongi-do and september to November respectively. Quantity and quality of by-product biomass show big difference depending on the crop species and cultivation periods and these difference bring up that accurate biomass estimation should be considered during planning of biomass utilization and technology selecting for biomass converting to energy and other forms.

Objectives : The aim of this study was to compare the effect of needle retention(NR) and electro-acupuncture of low(EA(L)) and high(EA(H)) frequencies at $SP_6$ and Sham point in rats. Methods : Intestinal hypermotility was induced by feeding carbachol and experimental groups divided mainly into 7 groups which were normal, holder, control, acupuncture in normal state of rats, pre-treatment of acupuncture(NR, EA) in hypermotility, post-treatment of acupuncture(NR, EA) in hypermotility. We fed charcoal to them after the treatment and measured the travel rate of charcoal in the gastrointestinal track so that which treatment affected more in intestinal hypermotility. Results : As the following study, each acupuncture ways of EA(L) had significant effect of decreasing travel rate on intestinal hypermotility than EA(H) and NR. The comparison between pre-treatment and post-treatment, pre-treatment had slight more effect than post-treatment but not significantly. There was more affected at $SP_6$ than Sham point on this study. Conclusions : There were 21 groups to find out which treatment was best to slow down the intestinal motility and $SP_6$-EA(L)-C had significant effect compared with control group at the figure than any other groups. That meant $SP_6$ had effect on gastric disorder such as intestinal hypermotility and its' effect had more prevention than cure. Further study was needed to have more precise effect of EA and $SP_6$.

Purpose: The purpose of this study was to test the predictive validity of the Fall Assessment Scale-Korean version (FAS-K) and to find the most appropriate cutoff score to screen high-risk fall groups in adult patients in general hospitals in Korea. Methods: We performed a prospective evaluation study in medical and surgical ward patients at two major general hospitals in Seoul. Data were collected from Nov. 1, 2018 to Feb. 28, 2019, nurses performed 651 observation series. The researcher measured the fall risk assessment score by applying FAS-K, MFS (Morse Fall Scale), and JHFRAT (Johns Hopkins Hospital Fall Risk Assessment tool) to the patients twice a week between 10 am and 12 noon. Data were analyzed using Pearson's corelation coefficients, and the sensitivity, specificity, predictive value, and the area under the curve (AUC) of the three tools. Results: The FAS-K was positively correlated with the MFS (r=.70, p<.001) and the JHFRAT (r=.82, p<.001). According to the receiver operating characteristics (ROC) curve analysis of the FAS-K, sensitivity, specificity, and positive and negative prediction values were 85.3%, 49.4%, 8.5%, and 98.4%, respectively, when the FAS-K score was 4. Therefore, the cut-off score of the FAS-K to identify groups with high fall risk was 4. Conclusion: The FAS-K is a valid tool for measuring fall risk in adult inpatients. In addition, the FAS-K score, 4, can be used to identify high-risk fall groups and know specific points in time to provide active interventions to prevent falls.

글로벌 금융위기를 겪고 난 이후, 주요 선진국에서는 가계부채/GDP 비율이 하락하는 경향을 보이고 있으나, 우리나라는 여전히 상승추세에 있으며, 가계부채 중 제일 큰 비중을 차지하는 주택담보대출은 최근 주택가격 하락으로 하우스푸어를 양산한 결과를 초래하였다. 본 연구는 최근 사회적 문제로 대두되고 있는 하우스푸어의 규모를 분석하는 한편, 하우스푸어의 형성배경에 주목하였다. 이는 하우스푸어의 문제가 일차적으로 개인과 금융기관 간의 금융거래에 기인하는 문제임에도 불구하고, 다양한 사회경제적 요인이 내재하고 있음을 간과할 수 없기 때문이다. 또한 이들 하우스푸어 문제를 해결하기 위해 사회적으로 어떠한 정책 방향을 설정해야 하는지 공적 개입 측면에서 현황과 향후 방향을 제안해보고자 한다. 우선 재무적관점에서 하우스푸어 규모를 추정하기 위한 판단지표로 DSR, LTA를 활용하였다. 재무적 위험을 판단하기 위한 임계치로 DSR은 40%, LTA는 100%로 가정하였다. 한편 LTA 산정과정에서 부동산자산의 평가액은 조사가격의 60%와 100%의 두가지 경우를 가정하였다. 다음으로 하우스푸어의 형성배경으로 사회 경제적 여건변화에 따른 가계의 차입의존도 증가, 금융기관의 과잉 대출경쟁, 부동산 시장의 장기침체, 주택담보대출 관련 제도적 문제 등이 원인인 것으로 파악되었다. 이처럼 하우스푸어의 발생에 대한 책임소재는 개인적인 문제 뿐 아니라 구조적 요인과 정책실패요인도 존재하고 있으며, 주택시장과 국민경제에 미치는 영향을 간과할 수 없다는 점에서 공적 개입의 필요성이 존재한다. 공적개입의 기본 방향은 공적 자금 부담을 최소화하고 시장기능을 활성화하는 차원에서 이루어져야 할 것이다. 또한 현재 하우스푸어 관련 정책으로 수행되고 있는 희망임대주택 리츠사업의 경우, 장기적으로는 대출거래 당사자인 대출기관도 책임을 부담하는 방식으로의 개선이 필요하다. After global financial crisis, the ratio of household debt to GDP was decreasing in other advanced countries such as the U.S., and the U.K. and so on. But, in Korea, household debt (of which residential mortgage loan account for a large part) ratio is still increasing. This paper focuses on the scale and characteristics of households in negative housing equity (those are called House-poors in Korea), and also the socio-economic backgrounds of the formation process. In financial perspective, the problem of negative housing equity depends on financial debt repayment capability. We used DSR (Debt Service Ratio) and LTA (Loan to Asset ratio) as financial indicators to evaluate the debt repayment capability. The critical value of DSR is assumed as 40%, and LTA 100%. The socio-economic backgrounds of the House-poors are as follows : increasing households debt dependency, over lending competition of financial institutions and unreasonable loan in household economy, instability of real estate market, week regulation on mortgage loan. Finally, this paper suggests some implications about the range and the target of public intervention.

수도권 보금자리주택 대상계층의 지불가능성 분석: 공공분양, 10년임대, 분납임대주택을 중심으로

최은희,김옥연,이종권,Choi, Eun-Hee,Kim, Ok-Yeon,Lee, Jong-Kwon 한국토지주택공사 토지주택연구원 2013 LHI journal of land, housing, and urban affairs Vol.4 No.4

본 논문의 목적은 대상계층을 설정하고 유형별 공공주택을 공급하는 보금자리주택을 평가해 보기 위한 것이다. 특히 수도권 보금자리지구가 지정되고 보금자리주택 공급이 발표되면서, 정책대상계층의 접근성에 대한 논의가 불거졌는데, 본 연구에서는 등장한 여러 논의 중에서 두 가지에 주목하였다. 하나는 주변시세애 비해 과도하게 낮게 책정된 분양가 혹은 임대료로 인해 청약에 당첨된 입주자에게 역시 과도한 개발이익 수혜가 돌아가는 것이 아니냐는 것이고, 다른 하나는 그렇게 낮게 책정된 분양가 혹은 임대료라고 하더라도 일부 지역의 경우 주변 시세가 워낙 높아, 저소득층이나 무주택 서민인 정책대상계층이 접근하는 것이 쉬울 것인가 하는 것이다. 두 가지 논의는 완전히 다른 것 같으면서도 다르지 않다. 상대적인 가격에서는 우위를 점하지만, 절대적인 가격에서는 여전히 낮지 않다고 보는 것이기 때문이다. 본 연구는 이 두 가지 논의에 착안하여 분석을 시도하였다. 특히 보금자리주택은 저소득층을 위한 장기공공임대주택(국민임대주택, 영구임대주택 등) 뿐 아니라 공공분양주택과 유사한 역할을 하는 10년임대주택과 분납임대주택도 존재하는 점을 감안하여 이 세 가지 유형에 대해 정책대상계층의 지불가능성이 어느 정도인지 파악하고자 하였다. 유형별, 지역별, 면적별 지불가능성의 차이를 비교해 봄으로써 기존의 논의에 대한 의문을 어느 정도 해결해 보려고 했으며, 향후 공공주택 공급 프로그램과 관련한 정책적 시사점도 도출해 보고자 하였다. The purpose of this paper is to appraise Bogeumzari Housing Program(BHP) which is providing public housing of different types for the target brackets on a matching system basis. Especially, on government's announcing BHP plan with the designation of several Bogeumzari districts in Seoul Metropolitan area, they raised a question about target groups' receiving the benefits of BHP plan and this paper focuses on the question. We tried to analyze two topics. First one is about the exorbitant windfall profits to the future potential residents derived from low price or rental cost of Bogeumzari Housing in comparison with neighborhood's market price. Second one is the low possibility of low-moderate income household's access to absolutely high price Bogeumzari Housing that is because the market price is so high in some area. BHP includes not only long-term public rental hosing(Permeant rental housing, National rental housing) for low income households but also other types of public rental housing(10-year rental housing, shared-ownership rental housing) for moderate income households. So, in this study we tried to find out the affordability of each bracket in three public housing types, which are public sales housing(condominium), 10-year rental housing and shared-ownership rental housing. Through analyzing the housing affordability by types, regions, size, we tried to seek the answer to the controversy and propose policy implications related to the future public housing programs.
